BACKGROUND Field of the Disclosure Examples of the present disclosure are related to semi-automatic firearms and/or accessories for semi-automatic firearms including a new firearm system and/or conversions of existing firearms to the system.
Background Firearms are a common tool in America for self-defense, hunting, and recreation. Self-loading firearms are particularly useful in defense of one's life because, as opposed to single shot or manually reloaded firearms, it allows more shots to be made in less time greatly increasing the opportunity for the defender to stop a threat. Self-loading firearms are very useful for other lawful purposes as well. Disabled persons may not have the required body parts or dexterity to pull a trigger but wish to be able to use a firearm for self-defense and lawful purposes. Or, disabled persons, may have one arm and hand with normal dexterity, but lack a second hand capable of supporting a larger firearm designed for two handed use, but they would still like the benefit of being able to comfortably support and fire such firearms. Or, fully able-bodied users may wish to use a self-loading firearm in a way that can increase their rate of fire in lawful situations such as self-defense where the increased rate of fire is beneficial or potentially life-saving for the users. Some ordinary triggers can have pull weights requiring 5 to 12 pounds of force to activate the trigger in order to fire the firearm. These forces are small for the stronger muscles of the arms and torso, but can be burdensome, prohibitive, or painful for disabled persons with low dexterity in their hands or missing one or more fingers or hands. Current triggers and operating mechanisms do not allow for the user to use the stronger muscles of their body to activate the trigger or fire hand held self-loading firearms.
Current semi-automatics firearms largely use a trigger that is pulled with a single finger to fire the gun, requiring fine motor skills. A pushing movement would utilize gross motor skills requiring less fine motor skills, benefitting disabled shooters and increasing a person's ability to more quickly fire a self-loading gun. Slam fire guns exist that are usually rudimentary firearms consisting of two parts where a round of ammunition is manually loaded into the front half of the firearm containing a barrel and chamber, and a second half of the firearm containing a firing pin slides over the first half and is slammed into the round striking the primer and firing it. Such weapons are not self-loading making them poorly suited for self-defense. Some firearms are fired using a paddle like trigger that is pushed with the thumb(s), somewhat similar to an embodiment of this invention, where while holding nearby grips for control with the other fingers from the rear of the firearm, the thumbs can be pushed into a trigger. Such firearms as a M2 Browning machine gun are usually heavy and mounted on a stand in front of the shooter where the trigger and/or grip is at the rear far end of the gun. These trigger systems and their host firearms still require a good degree of fine motor skills, and are ill suited for portability such as firing while carrying the gun without mechanical supports or mounts.
Slidefire Solutions markets a patented system where two sections of the gun are pulled away from each other and a finger held on a ledge pulls the trigger designed to facilitate an almost automatic like bump fire sequence of firing. This invention works in the opposite direction allowing the user to push into the trigger rather than pull which is an important distinction because pushing allows for firing with the larger more capable muscles of the body, and this invention is not designed to bump fire, where the recoil impulses here are the opposite direction needed to aid in bump firing. That distinct difference allows for controlled firing of the self-loading firearm where each shot must be intentional. A company, Ironhorse Arms, may have filed a patent application on a trigger operated by a thumb for an AR-15 style of firearm. Their trigger is a paddle not unlike that of the Browning M2 Machine Gun that is positioned inside of the grip and is positioned inside of the grip in the center of the gun and in line with the barrel. Thumb paddle triggers aren't new. Our thumb triggers are designed to be positioned where the user's thumb would normally lie when firing a conventional pull trigger, that is, off to the side of the grip where the thumb of the shooting hands starts to wrap around the grip allowing for a stronger grip and ease of converting existing firearms.
BRIEF SUMMARY OF THE INVENTION The firearm has two sections or has been modified to have two sections that can move independently of each other in opposite directions, in line with the barrel. One section contains the barrel and a trigger that can be pushed forward to activate the gun. The second section contains a trigger activating rod, edge, or object or it positions or supports a body part such as a finger or thumb and may contain a hand grip or shoulder stock for support and/or leverage. A shooter holds the firearm up using up to two hands and optionally shouldering it for support and aims to shoot. The front portion of the gun is held steady by a shooters support arm or rested in place on a ledge, surface, or mount. The shooter then uses their shoulder or hand to push the second section forward relative to the first. If the shooter is using a trigger activating device in the second section, as the second section moves in the direction of the first, the second section drives the trigger activator into the push activated trigger. If the shooter is using their finger, thumb, other body part in lieu of a mechanical trigger activator, the body part can rest still on a ledge or support around the grip, and as the second section is pushed into the first, the body part is pushed into the push activated trigger without a need for an independent movement of that same finger, thumb, or body part. When the activator object or body part pushes into the push activated trigger, it activates the next step in the firing sequence of the self-loading firearm such as the release of a hammer, striker, or other object or impulse that ultimately causes the cartridge or round in the gun to be fired. Once fired, the self-loading gun cycles, typically ejecting the used ammunition, resetting internal mechanisms of the trigger, and loading a new round of ammunition to be fired. When the shooter retracts the first and second portions of the firearm from each other, the trigger will return to its starting position under spring pressure and the firearm is ready to be fired again, assuming a new round was chambered, with a new push of the second part into the first.

FIGS. 1, 2, and 3 show, with no innovations, a side and two perspective views of an example of a typical semi-automatic firearm receiver, also known as a frame, from the left side FIG. 1, bottom right FIG. 2, and bottom left FIG. 3, with a receiver extension tube (5) that is threaded into a tower structure in the receiver (9). The receiver extension tube in this particular firearm is needed for internal components to move and operate, but also notably acts as a possible frame to attach a rifle stock or other stabilizing device to. This example receiver shares much in common with many modern semi-automatic firearms. Many other semi-auto firearm frames and receivers may not utilize a receiver extension tube, but may use a sturdy stock with or without an accompanying stock frame that serves the same purpose as the receiver extension tube in securing a stock or other contact point aid such as a cheek piece or stabilizing arm brace with or without the need to thread such stock or frame into the receiver. This firearm is shown setup to receive very common types of semi-automatic fire control group layouts with a hammer secured inside the receiver via a pin at (2), a trigger and disconnector secured via pin at (6) down and to the right of the hammer pin hole from the left side view, and an opening (3) in the receiver usually somewhere above the trigger pin hole that will secure a safety selector that can be toggled to put the firearm in safe, or ready to fire positions utilizing at least two different positions. Many firearms have a permanently connected trigger guard, the example semi-auto receiver shown has a removeable trigger guard (13) utilizing mounting point pin holes (7) and (12) to be secured to the gun. Many semi-automatic firearms allow for a near vertical handgrip (8) that can be removed and/or replaced on the firearm. Some attach using panels via screws to the side of a grip frame, this example has a feature for the user to secure a removeable grip through a diagonally secured screw (10) through a threaded hole (14). Some semi-auto receiver frames are one central piece, this example firearm consists of a lower receiver that can attach to an upper receiver (not pictured) that holds other vital semi-auto components such as a barrel, locking lugs, bolt carrier group, return springs, and gas operating system and other components. This example firearm receiver known as the lower receiver will attach to an upper receiver via removeable pins through pin holes in the front (1) and the back (4). A trigger opening (11) allows the trigger to extend out from inside the receive to outside the receiver into the trigger guard area.
Fires 4-19 show the main parts of an example typical semi-automatic firearm's fire control group, presented without innovation. This example shows a typical fire control group layout that could be utilized in the system of innovations for this invention. The safety, FIG. 11 has a cylindrical body with smooth outer diameters on both ends (20)(21) that allow the safety to be placed through the safety hole and rest and rotate with those ends on each side of the receiver. It also has a lever to assist in applying rotational force and the lever has a flat bottom wider than the cylinder to stop the safety from being over inserted in the receiver. The hammer, FIG. 5, is secured via pin at position (2) inside the firearm receiver. The trigger, FIG. 8, is secured via pin inside the firearm at position (6) which is also shared with the disconnector, FIG. 6 all in line with the hammer. From the left side view, the hammer is under pressure from the hammer spring, which wraps around the pin holding the hammer in place at (6) exerting a force to rotate counter clockwise about, as viewed from the left. The trigger is under pressure from trigger spring, which wraps around the pin holding the trigger to rotate clockwise about position (6). The disconnector shares the same pin/pivot position as the trigger but rotates independently from the trigger. The disconnector fits in a channel in the top of the trigger (17) and a small disconnector spring that fits in a spring channel (18) exerts pressure from the trigger onto the disconnector spring face (16) which rotates the disconnector counter clockwise about position (6).
With the system at rest, as shown in FIG. 14, the trigger is pressured to rotate clockwise and the hammer is pressured to rotate counter clockwise. The trigger has a sear face (28) that pushes into the hammer's locking face (27) so that neither can rotate as shown in FIG. 16, an enlarged view of a marked section of FIG. 14. When the firearm user pulls on the trigger pull face towards the rear of the firearm with their finger, it causes the trigger to rotate counter clockwise which drops the trigger sear face below the hammer's lock face. This new position of FCG Assembly is shown in FIGS. 17-18. At this point the hammer has been released and will rotate counter clockwise to strike a firing pin starting the firing sequence of the firearm. A hammer is used in this example, but the trigger could possibly also release a striker or other mechanism that would lead to the firing of the firearm with most of the operating mechanism remaining largely the same. Depending on the semi-automatic firearm, gas pressure, inertia, or recoil or other energy source will cause the bolt carrier or similar mechanical device to travel rearward which pushes back on the hammer's strike face (24) rotating it clockwise from the left side view back towards it's starting position. Eventually the hammer rotates clockwise far enough that it's hook faces (25) comes into contact with the hook faces (26) of the disconnector. The hammer's hook faces push the disconnector to rotate clockwise until the disconnector's hook faces are cammed over the hammer's hook faces, at which point the disconnector spring forces the disconnector to move counter clock wise and the disconnector hook faces slide over the hammer's hook faces which catches the hammer and locks the hammer and disconnector together.
As the shooter releases pressure from their finger on the trigger pull face, the trigger starts to rotate clockwise. The trigger disconnector channel (17) has a curved cam surface (19) near its front that will push up on the disconnector's lever surface (16) which causes the disconnector to rotate counter clockwise releasing it from the hammer. The geometry of the hammer and disconnector hook faces are such that by the time the hammer is released from the disconnector, it can start to rotate counter clockwise toward striking the firing pin. The trigger sear face (28) is above the hammer lock face (27) and the hammer rotates counter clockwise a very short rotation until it locks into its resting position against the sear and the whole system is at rest and ready to be shot again. The safety selector FIG. 11 at this point can be toggled to its safe position where cams block the trigger from moving counter clockwise preventing the gun from being able to be shot, or kept in the fire position or other positions that allow the system to be fired. Other possible safety mechanisms could be used in lieu of the example safety operating principles, FIG. 11.
FIGS. 20-28 show an example of a novel push trigger, FIG. 20, that can be facilitated by the addition of a new pin hole to semi-automatic firearms, in this example, by use of a novel trigger guard, FIG. 22, that is a frame for the new hole. The trigger guard is an example of an innovative removeable trigger guard that adds a new pin hole (31) for a push style trigger for a semi-automatic firearm and like the example trigger guard (13) shown in FIG. 3, can be installed as the trigger guard. In this example, the trigger guard is pinned in to place at and rotated about [9] and secured by pin at [8] resulting in a finished position shown attached to a receiver like FIG. 1 in the view of FIG. 24. A new style of “push trigger” like FIG. 20 can be inserted in between the tines (32) of the trigger guard, FIG. 23, where a pin is pushed through the new hole (31) securing the new push trigger in place. Example rotating push trigger, FIG. 20, is a rotating style trigger with rounded push face that works by using a trigger activating device such as a finger, body part, or object to push into the trigger on the push face (30) towards the front of the firearm. This push movement is as opposed to a non-innovative or traditional trigger like FIG. 9 that is pulled towards the rear of the gun. This rotating trigger could have a lever (29) or other mechanical device that interacts with a transfer trigger like FIG. 25. The transfer trigger can be very similar to a traditional or non-innovative trigger, but includes at least one additional feature that interacts with a push style trigger, likely located in front of the transfer trigger. This particular push trigger lever FIG. 20, shown at rest in in the view of the assembled hammer, disconnector, transfer trigger, and rotating push trigger in FIG. 27 and the enlarged view of the sear/hammer relationship in FIG. 28 marked from FIG. 27, will fit into or over a cavity such as the transfer trigger cavity (33) or a ledge, surface, other feature such that when pressure is applied to the push surface of the example rotating push trigger shown in FIG. 20, the lever (29) rotates down hitting the surface inside the cavity (33), which also pushes the sear surface down through downwards via rotational movements until it gets to its new position shown in FIG. 29 and in FIG. 30, an enlarged view marked from FIG. 29, releasing the hammer, striker, or activating any other firing mechanism which starts the firing sequence of the firearm. A trigger spring will push the sear face and example transfer trigger surface (33) back up which pushes the push trigger lever back up returning the push trigger back to its rest position, FIG. 27. The push trigger FIG. 20 is shown as being curved, but can also have a flat push surface such as FIG. 31. The replacement trigger guard can also just simply be parts that snap together over the firearm and/or existing trigger guard serving the same purpose. The perspective view of FIG. 33 shows how the push trigger can reach into the transfer trigger and FIG. 44 shows the assembly of FIG. 24 with the push trigger added.
FIGS. 35-51 show an example of an alternative to the rotating push trigger where the push trigger has directional movement versus rotational movement. The example directional push trigger FIG. 35 is shown in FIG. 38 at rest, from a left side view. The example directional push trigger moves in the direction of the elongated pin slot (37) with the trigger having been fitted by pin into the same new pin hole (31) from FIG. 22 where the trigger moves directionally only towards the front of the barrel of the firearm when pushed, and moves back towards the rear of the gun when released. The directional push trigger has a cam face arm or similar mechanical feature that reaches through a trigger port of the receiver and fits in with or into a transfer trigger like the example transfer bar trigger FIG. 40 which is mounted in the receiver via pin through the pin hole. The example transfer trigger has a cam surface (39) which in this example is a rounded extrusion or pin where cam surface (34) of the example push trigger slides into the directional transfer trigger and interacts with the cam surface (39). In this example, when pressure is applied by the user's finger, body part, or other device against the push face (36), the directional push of the push trigger forward toward the front of the gun also moves cam surface (34) in the same direction forward. As the cam surface (34) moves forward in contact with cam surface (39), it rotates the transfer trigger counter clockwise, moving the sear surface down relative to the hammer. When the directional push trigger system has been moved far enough to reach the position illustrated in view FIG. 43 and FIG. 44, the hammer or striker has been released from the sear and will continue the firing sequence of the firearm. When pressure on the push face is lessened or released, pressure from a trigger spring will rotate the transfer trigger clockwise about the trigger pin which pushes cam surface (39) up into cam surface (34) which pushes the directional push trigger back into its rest position and the system is reset and ready to be activated again. Surfaces like (38) which will rest against the receiver or other body and surfaces like (34), (39), (35), and (40) which interact with each other will prevent lateral directional push trigger from rotating about the pin, in the new pin hole in the trigger guard area which it is connect to, while it translates directionally via the elongated pin slot back and forth during operation of the firearm and invention system.
A foam padding like FIG. 45 or padding of any suitable construction can be applied to any of the push trigger surfaces, possibly with an adhesive backing (41), as depicted in view FIG. 48 to make shooting while using the invention system more comfortable while using a finger or body part as the trigger activator.
The features of the translating push trigger can be incorporated directly into the sliding grip, described later, to remove the need for that trigger as a part in the system.
FIGS. 52-75 show an example of a slam stock assembly and depicts examples of components that would work for the invention and its systems. FIG. 52 shows a firearm receiver and extension tube equipped with the push trigger system like the example covered earlier in FIG. 27 and a grip screw. FIG. 53 and FIG. 55 are an example of a slam grip which can be used by itself, and FIGS. 54 and 56 is an example of a Unified Slam Stock body that could work. These are meant to be able to slide back and forth and this embodiment of the Unified Slam Stock body includes a lug (42) that can be used to limit travel movement when the front hits a fit object and/or the rear hits a fixed object in the system when sliding. Such a lug or similar interface could be on the grip, stock, or both portions of the sliding bodies. The Unified Slam Stock Body could be divided into two or more parts, including a Slam Grip and Slam Stock and then connected together permanently as in being welded, epoxied, glued, melded, etc. together, or mechanically attached through pins, latches, joints, etc. It could have been molded or machined as a single piece as well. The grip could feature a female rail slot (43) to be made to only move back and forth linearly. The Unified Slam Stock body [05b] can be slid over the receiver extension tube like through an opening (44) or with rails for an appropriate other stock frame connected to the receiver and then for additional support can be slid over a railed grip plug FIG. 59 which in this example has a square rail (45) that interacts with a female rail slot (44) in the Slam Grip A finger, body part, or object is utilized as a trigger activator and placed towards the front of the Slam Grip in a way that it is in front of the push trigger push face and the firearm user will hold the firearm steady while pushing on the Unified Slamstock Body, Slam Grip [07a] and/or Slam Stock [08a] such that the trigger activator is pushed into the trigger push face starting the firing sequence of the firearm. The unified Slam Stock body slides back and forth directionally along axis of its mounting body(s) which as shown here are an extension tube and grip plug.
This example receiver, FIG. 52, has an integral threaded grip nut that fits through inside the inside of the grip plug slot (46). In this example, the grip plug is secured to the receiver via a grip screw fed through the bottom of the grip plug through a diagonal hole (47) into the threaded grip nut of the receiver. FIGS. 64-67 show the sample grip plug without the screw coming through the diagonal hole. FIG. 64 shows the plane moving down the middle from front to back for the cutaway FIG. 65 where you can see the diagonal hole more clearly. Other methods of attaching the grip plug can be adapted to various other firearm designs including using specialized grip panels that attach to the sides of fixed grip frames, etc.
A limiter device such as this example limiter FIG. 69 is used to restrict the movement and travel distance of the unified Slam Stock body, both forward and rearward. It uses a clamp body (48) that holds hooks (49) where the clamp body slides over the extension tube or stock frame or is placed ahead of the Slam Stock and secured in place which limits the unified Slam Stock Body's forward movement and then the hooks protrude out from the clamp body and can catch onto the lugs (42) in the Slam Stock to prevent it from travelling any farther back by the rear of the lugs hitting the hooks and the front of the lugs running into the clamp bodies (48). The importance of a limiter is to limit the pressure from being applied to the trigger push face by the activator. For example, some conventional triggers can be rated for pulls of 5-12 lbs of force. They've been designed to be pulled by the relatively weak fingers where maximum pull strength of the associated finger muscles and tendons involved are not too much more than the trigger pull weight. In the case of the invention system, major muscles are being used from the more massive body parts such as the arm, chest, and shoulders where forces could possibly exceed 100 lbs of pressure. With a conventional and non-innovative trigger, in most cases you're using the fleshy portion of the underside of a finger to pull on the trigger which acts as a natural padding and shock absorber. When using a finger as the activator in the systems of this invention, you'll likely be using the bony and trim top surface of the finger for pushing against the trigger. Pads like the foam pad that was shown in FIG. 45 will surely prevent some discomfort, but if you can slam a finger too far into the trigger or with enough force, it can still result in serious pain or injury. So, the user will necessarily need to be able to adjust the forward movement of the unified Slam Stock body so that over travel into the push trigger is prevented and limiting rearward travel so that the stock body doesn't fall off of the firearm is also helpful and this example of a limiter is one such way of achieving those goals. FIGS. 72-74 are alternate views of a stripped lower receiver showing the assembly of the grip plug on the receiver. FIG. 75 shows FIGS. 52-74 assembled together with miscellaneous other parts previously covered for reference.
FIGS. 76-84 are alternate views of FIG. 53, an example of a Slam Grip portion of a Unified Slam Stock body. The Slam Grip contains a hollowed inside body (50), as can be seen in FIG. 76, that can wrap around the grip plug and the trigger guard region of a firearm. This particular example of a slam grip also has the female slot that interacts with the rail of the grip plug. Other versions of a Slam Grip are possible, this is just one version. A common feature to most is some feature provisioned to allow or assist a trigger activator such as a finger, body part, or object to interact with the push face of a push trigger. This Example Slam Grip features a ledge (51) that the shooters finger can wrap across. There is at least one such ledge on each slam grip, but it could also be designed as shown with two such ledges, one on the left and one on the right. The finger can be draped across just one such ledge, but can be draped across both such ledges to act as the trigger activator where draping the finger across both ledges gives the highest chance of the finger activating the trigger. The feature of a rail or guide system aiding in preventing rotation of the slam grip and unified slam stock body will be common, where the slam stock systems are only meant to be directional in one linear dimension towards the front and back of the firearm in line or parallel with the barrel.
FIGS. 85-89 show more views of the Slam Stock body that could work for the inventions system and FIG. 90 is a full assembly of the entire system. An opening in the front of the stock body allows the slam stock body to slide over the receiver extension tube or a stock frame, until it is stopped by the limiter which in this example is clamped to the tube. This particular example is meant to be made as one piece with the Slam Grip but is pictured separate for detail and would be connected at the t-spine face (52) of the slide stock body with the rear of a slam grip. There are other ways to increase strength of the connecting bridge between the end of the slam stock body and the grip frame, but a t-spine is used here because of it's thin, light, and mechanically strong support cross-section.
FIGS. 91 and 92 are perspective views of the assembly in FIG. 90. FIGS. 93-100 show the clamp on example limiter system in more detail. FIGS. 93-96 are the bare two half bodies of the clamp shown from the left side with projected views around it. This particular example of a limiter is shown as a bolt-on clamp where friction holds the device in place across and along the receiver extension tube The limiter in this example has a top and bottom where screws are used to tighten the bottom to the top and hold them against the receiver extension tube, locking the limiter in place on the tube through friction, where. The lower body has two holes (53) that hooks can slide into. The back-side face (((((54) of the limiter stops the forward travel of the stock body. FIGS. 97-100 show an assembly of the clamp bodies on the receiver extension tube, and the screws and hooks. The hooks can be adjusted for length and are secured in place in this example by friction via set screws under the bottom limiter body. The hooks have a stop surface (55) which interact with the stop surface of the lugs of the slam stock body. These hooks can be adjusted for length to allow greater or lesser possible rearward travel of the stock body or even lock the stock system into zero allowable movement and prevents the stock body and firearm from sliding off of each other. The limiter can take many shapes and forms, but function is to limit either forward, rearward, or both forward and rearward travel and can be integral to another component of the system or built in another way such as a quick release clamp, series of locking and selectable solid steps, etc. and while this example used hooks as the rearward stop, the rearward stop can take many forms as well including a second separate limiter or feature built into another component of the system.
FIGS. 101-108 are alternate views of FIG. 76, a non-innovative receiver; FIGS. 109-112 are a non-innovative safety for the receiver; FIGS. 113-116 are a non-innovative safety detent for the receiver; FIG. 117 is a spring for the safety detent; FIG. 118 is an assembly of a non-innovative buffer detent for the receiver and shown with a spring; and FIGS. 119-121 are more views of the buffer detent. FIG. 102 is shown as a mirror image across the back side of FIG. 101. FIG. 105 is an enlarged view marked in FIG. 103 from the cross section marked in FIG. 101 and shows a cylindrical cavity (56) that's used to house a buffer detent. FIG. 106 is an enlarged view of the area marked in FIG. 104 of the cross section marked in FIG. 102 and it shows a two section through hole (57) that a safety detent will fit into. The safety, FIG. 109, is shown from the left hand side in it's ready to fire vertical position. A safety detent is inserted into the safety through hole and is fed into contact with the detent cam path (58) feature of the safety which has at least two lobes (59) along the path that can lock the detent and safety into a particular position. In this case, the two positions 90 degrees apart representing safe and ready to fire and there is a flat section (60) cut across the safety that allows room for the trigger to rotate enough to release when in this position. The safety detent spring will be locked into the receiver from the bottom of the detent through hole by items like the grip or grip plug. The spring pressures the detent into the lobes locking the safety in a position by friction. The user can toggle the switch, and with enough rotational force applied to the safety, the lobe will cam the detent downwards and into the detent cam path and the user can continue to rotate the safety into its next position where the detent is pushed into the next lobe locking the safety into the next position. This particular example firearm has a mechanical device called a buffer (not pictured) that under spring pressure from rear of extension tube moves linearly in alignment with the barrel. It needs to be held in place inside the receiver extension tube and it is held in place with a buffer detent, FIG. 118. The buffer detent has a cavity (64) that a buffer detent spring (63) is fit into and both the buffer detent and its spring are inserted into the blind buffer detent hole in the receiver. The receiver extension tube is inserted and turned into the threaded tower of the receiver until it can no longer move forward without running into the buffer detent pin stop (61) where surface (62) pushes against the front bottom side of edge edge of the receiver extension tube.
FIGS. 122-132 are an example of another possible layout of the slam stock system but built around an innovative Slam Receiver firearm receiver frame that could make several components of the semi-automatic slam fire system integral to the receiver or frame or better implement the system in general versus using only external parts to convert a firearm to use the system. FIGS. 122-128 show a stripped Slam Receiver; FIGS. 129 and 130 are views of just the slam grip portion, FIG. 131 shows a modified receiver extension for this example of a Slam Receiver system, and FIG. 132 is an example assembly of a complete Slam Receiver system. The stripped Slam Receiver is an example of how a receiver with various components of the invention's system could work when made integral with the receiver. It could share many features in common with existing semi-automatic firearm receivers and frames and the example firearm receiver Similarities could include the placement of a hammer pin hole, trigger pin hole, safety opening, front and rear pin, a threaded tower, and new pin hole for the push triggers that would negate the need for a removeable trigger guard acting as a frame for that hole. This example Slam Receiver also has a slide lock opening (65) for features that would negate the need for at least part of the clamp on slide limiting system, its own version of a safety detent hole (72), and a detent passage for the slide lock (73). The new Grip frame has slide lugs (81); a t-spine rear profile instead of being a flat black and that mates with a corresponding slotted grip passage (78), and a catch tower (77) that could also help to mostly replace the need for an external limiter like described in Page 9, where the example slam grip and the new example slide stock body (84) are attached as part of the new unified slam stock body, is slid into place with the receiver by having the sliding lugs pass through the outside of the opening (67) on the left side and opening (69) on the right side of the receiver where once the slide lugs have passed into the trigger guard area (70), the whole unified slide stock assembly can be lifted up and the catch tower moves into the catch cavity (76) of the example slam receiver and t-spine fits into the spine passage (75) of the example slam receiver. The threaded grip nut area of the prior reviewed example receiver and the prior reviewed grip plug are removed from this example of the invention system and the grip attachment area (78) and that area now interacts directly between the example slam receiver and the example slam receiver grip frame and it's hollow (82). When the unified slam stock body has been set into its correct position relative to the slam receiver, the cylindrical receiver extension tube is passed through the slide stock opening and threaded into the receiver tower. At this point, the unified slam stock body has now been locked into its vertical up and down position and rotational axis relative to the firearm, but can move linearly front to rear along the same axis as the receiver tube. The slide lugs fit into the slide lug recess (66) of the receiver which provides support preventing the unified slam stock body from rotating about the axis of the extension tube, and also acts as a limiter preventing the unified slam stock body from travelling any farther back than the reach of the recess. The catch surfaces (71), (80), and (83) of the grip frame interact with contact the surfaces in the catch cavity which acts as a maximum possible movement limiter for both forward and rearward travel of the unified slam stock body. The forward catch surfaces need not be identical. The flat ledge (68) of the grip area extends down from the safety opening as well as the safety detent hole. The safety detent hole's path upwards is seen starting at the bottom of the grip area ledge and terminating where it extends into the receiver's safety opening. The trigger guard (71) on this example receiver is fixed in place but could just as well be made to be removeable with corresponding alterations.
FIGS. 133-138 show additional alternative views of a slam receiver compatible slam grip. FIGS. 139-142 show some detents used in the system, and FIGS. 143-151 show a slide lock that can be added to the system that installs and rotates in similar way as the safety allowing or restricting movement of slam grip and slam stock bodies. FIGS. 134 and 135 are crosssection views of the grip frame cut in half to a right and left side. FIGS. 136 and 138 are alternative perspective views allowing us to see better in the grip. The internal flat surface (85) of the slam receiver grip frame, despite being a moving surface, covers the safety detent hole in its fixed position to block its detents and spring from falling out. FIGS. 139-142 show detents and detent springs used with this receiver. One way to make the safety detent system work in this example receiver setup is to use two detents (86) and (88) facing opposite directions with safety detent spring (87) sitting between them. The top detent is being pushed by spring pressure into the safety as described in the prior example, and the bottom detent is getting pushed through the bottom of the safety detent hole into the flat internal horizontal of the grip which slides along parallel with the corresponding flat surface of the receiver. Both detents are locked in place by being sandwiched between the internal horizontal flat ledge of the slam grip on one side and the safety with the spring sandwiched between the two detents and exerting pressure on both in opposite directions. When the unified slam stock body is positioned and locked in place from moving up and down vertically, the bottom detent drags along flat surface as the grip moves back and forth while the firearm is operated. FIG. 142 shows the slide lock's detent (90) and spring (89) added to the system that's placed through the detent hole from the rear of the receiver. The detent points towards the rear of the receiver and is placed through the hole backwards with spring backing up against the safety and pushing the detent into the slide lock when the slide lock is placed into the receiver. A longer than normal buffer tube detent is shown in FIG. Because a lot of material is removed internally to fit the grip, the buffer tube detent uses the slide lock to keep it in place and must be longer so the bottom of the detent can't come more than halfway up the slide lock. FIG. 143 is an example slide lock that could be used in this invention system pictured in its released position, in the center, from the left side, with views projected out from that in the center comprising the rest of FIGS. 143-151. The slide lock in this example has a near identical detent cam path (91) and detent cam lobes (92) as the safety. In this example a detent is identical to safety detent is used to lock the slide lock into a particular rotational selection position. With the safety not yet installed in the receiver, the slide lock detent and slide lock detent spring are fed horizontally through the slide lock detent passage until the detent no longer obstructs the slide lock opening. The spring and detent will not slide out the safety opening. The slide lock is then slid into place from the left side of the receiver towards the right side. This particular slide lock example is made for one sided operation, but an ambidextrous version is possible. When the safety is also installed, the slide lock detent spring will rest on the smooth face of the safety in contact with the safety opening on the left side of the receiver. A small ball bearing can be placed at the end of the spring to reduce friction on the safety by the spring. At that point, spring pressure is going to force the detent into the cam path and lock into the lobes to secure the slide lock in a particular rotational position and selection. There are two positions and selections for this particular example slide lock. One is locked, and the second is released. Slide lock is shown in the released position. The slide lock has two catch release ledges, one on the left (93) and one on the right (94) sides to the slam grip's corresponding catch surfaces on its catch tower. When the slide lock is in its released position, the catch release ledges are horizontal and the vertical catch surfaces of the slam grip's catch tower can pass right under them until they run into the slam receiver's catch cavity surfaces. If the grip is pulled and slid towards the rear of the gun, the firearm user can rotate this example of a slide lock 90 degrees counter clockwise after applying enough pressure to cam the detent. After the 90 degree rotation, the slide lock's catch release surfaces will be vertical and parallel with [the vertically oriented catch surfaces of the slam grip's catch tower and squeezes into them and the slam grip's rear catch surface is squeezed into the rear of the catch cavity of the slam receiver such that the grip will be locked in place, unable to move forward or backward. At this point, the user can still push on the trigger and fire the gun so long as the safety is in fire position, however the user cannot use the sliding function of the slam fire system in firing the weapon. When the user wishes to put slide lock back into the released position, they need simply to rotate the slide lock 90 degrees clock wise and the slide function of the slam fire system is restored. Because of the depth of the detent cam path in this example, the slide lock would likely not be adequately secured from falling out the side of the firearm from just the detent. The elongated buffer detent could be used with its accompanying buffer detent spring and inserted what would be the buffer detent hole on the non-innovative receiver and in through the slide lock's buffer detent path. In metal machining, the buffer detent passage could start out much like the blind hole of the non-innovative receiver but with a deeper bottom and then the slide lock opening into the receiver is machined through much of the the detent hole that had already been machined. When the slide lock is installed in the receiver in any correct selection position, the buffer detent can be dropped through the top of the slam receivers buffer detent passage where the top part of the buffer detent ends up being completely surrounded by the receiver, and then towards the middle and bottom of the buffer detent, the detent fits jointly into the slide lock buffer detent path (95) on one side and the buffer detent passage and receiver on the opposite side. On this particular example, the slide lock buffer detent path is offset 6 degrees to match the cant of the buffer detent passage, and extends 270 degrees around the slide lock so that there is a 180 degree opening when the slide lock is in a particular position, and then an additional 90 degrees so that when the slide lock is rotated 90 degrees to the next position, there's still a 180 degree channel holding the buffer detent in place. This possible design for a slide lock would satisfy the needed buffer detent passage for this particular example firearm receiver and the buffer detent would also serve to lock the slide lock from being able to fall out the side of the firearm receiver. There are several ways to achieve the objectives of the slide lock to lock the slam stock system in place, this is just one such design. Previously we showed how the example limiter [09a] clamp on limiter with hooks had hooks that could be adjusted to prevent any movement forward or rearward of the unified slam stock body. Other designs could move the slide lock to an external location outside of the receiver, or be incorporated into the safety such that the safety fills the role of the slide lock and safety and could use other methods of performing the lockup.
FIGS. 152-159 are more alternate views of the stripped with various cross-sections exposed to better show internal features. FIG. 152 marks two cross-sections. A line that vertically splits the safety detent hole in half along the axis of the slide lock detent passage and then cuts out the right side of the model before the end of the receiver's fire control group pocket marks the cross-section view shown in FIGS. 153 and 154. A line parallel with that mark also rights on the opposite side of the receiver flush with narrowest part of the slam receiver's left side lug opening into the trigger guard area and then cuts out the left side of the receiver before the end of the receivers fire control group pocket and marks the cross-section views shown in FIGS. 155 and 156. We can see the safety detent passage leading from the flat slide surface on the right side of the slam receiver and terminating into the safety opening hole. A vertically running rounded male catch surface (96) is visible in FIG. 154 that correlates with a corresponding female rounded catch surface on the slam grip that limits travel of the slam grip and slam stock bodies. In FIG. 155, a vertically running flat catch surface (97) can be seen on the slam receivers left side inside of the catch cavity of the receiver. A similar surface is on the right side and the correlate with the vertical flat surface on the front of the slam grip's catch tower to limit maximum forward motion. FIG. 157 marks the cross section for FIGS. 158 and 159 that splits the receiver equally down the center of the receiver from front to back. The buffer detent entrance opening (98) and the buffer detent hole bottom (99) are visible from FIGS. 158 and 159.
FIGS. 160-164 show an example of a slam stock portion of a slam receiver compatible unified slam stock body. the slam stock body's opening (100) that goes from the rear coming out the front towards the front of the gun. If the hole was made slightly oversized, ribs (101) could be added the length of the hole that minimize surface area contact and friction with the receiver extension tube for the slam stock to slide back and forth on and increasing reliability of the system. FIGS. 165-168 show an example limiter that can be clamped onto the receiver tube in front of the stock body to fine tune the amount of forward travel possible by the unified slam stock body. While the particular slam receiver being shown in this context has been shown with internal limiting features, fine tuning the forward movement still ensures that too much pressure is not placed on the trigger which can cause damage to the firearm components and/or pain and injury in the case the trigger activator being used is a finger or body part. Particularly since human finger sizes can change drastically from person to person or with or without gloves, etc. This particular example limiter is shown as a two piece bolt on clamp that clamps on to the tube via friction and is secured by the bolts. However, various quick release lever clamp mechanisms including clam shell designs or integral mechanical feature modifications to the receiver, stock body, and/or stock frame could achieve the same purpose.
FIGS. 169-171 are alternate perspective views of FIG. 132, the complete slam receiver slam stock system. FIGS. 172-178 are more alternate views of FIG. 132, the complete slam receiver slam stock system. FIG. 172 marks the cross-section for FIG. 176 which cuts through the middle of the safety detents. FIG. 173 marks the cross-section of FIG. 177 which cuts down the middle of the firearm including the buffer detent, and it also marks the cross section of FIG. 174 which cuts along the example slide lock detent. Springs are omitted.
FIGS. 178-189 show more possible design and feature variations of slam stock and slam grip bodies. FIGS. 178-180 are an example of a stabilizer, that while not a stock, serves the same purpose of the slam stock bodies and in the invention system, just that it is not intended to be shouldered. This device is a stabilizer where weight to the rear helps stabilize the firearm which is front heavy and/or allows for the shooter to rest their cheek against the stabilizer, but the length of the device and surface area of rear are not designed for shouldering. This example shows that the slam stock bodies are applicable to more than just stocks. Other variations could include integrating an arm stabilizing brace instead of a rifle stock. These alternative slam stock bodies would be useful to place on firearms that are not considered “rifles” under statute, but that may be considered a pistol or other miscellaneous firearm that cannot have a rifle stock while under such legal classifications. FIGS. 181-183 show an example of another type of design the grip frames can take on, whereas other grip frames could have ledges to place a finger across partially or wholly, this example design has a retaining feature (102), in this case a hole, that either a finger, body part, or physical object can be placed through to act as the trigger activator. FIGS. 185-189 show an example of how a physical object activator (103), in this case a cylinder, can be placed in the path of the trigger to act as the trigger activator. Alternative object-based trigger activators could be a mechanical feature suck as a spike, ledge, edge, surface, cam, lobe, or any number of appropriate physical features that could be used to press into the trigger.
FIG. 190 shows an example of a possible dual trigger setup. This particular trigger system is very similar to the example trigger system in the assembly of FIG. 27 with the same push trigger, hammer, disconnector, and springs (not shown) but with hybrid transfer trigger (104) which combines the features of the example transfer bar trigger with an example traditional trigger like shown in FIG. 8. The hybrid transfer trigger contains the appropriate features to be activated by the push trigger, but has its own pull face surface to activate the transfer trigger directly without the push trigger. In this setup, when you push forward on your grip frame or unified slam stock body, it pushes the activator into the push trigger and when you release the trigger and move back to the neutral position you started, as the user, you have the option to push forward again to shoot, or you could pull back on the grip frame to pull the trigger activator into the hybrid trigger. At any point once the trigger system is reset, you have the option of pushing forward or pulling back to fire the weapon including continuing to push forward and pull back repeatedly. This is just one of many possible examples of a dual trigger setup where there must be appropriate space in between triggers area (105) to fit the trigger activator and allow for a reset of the trigger system before pushing or pulling again.
FIGS. 191-206 show an example thumb pushed trigger that is based on the directional push like FIGS. 20 and 35, but that are thumb activated. The thumb pushed triggers can utilize the same overall mechanism with the difference is that the directional push trigger has been replaced with a thumb activated push trigger that has a long arm (107) extending out of the trigger guard area of the receiver and extends back towards the grip where the user could use their thumb to press on push surface (109) to activate the trigger. It is shown here with a directional push trigger style setup like FIG. 35 but the arm could just as easily be adapted to the rotational push trigger system like FIG. 35 where you′d be able to press into the thumb push surface or push down on (106) the top surface of the extended arm to rotate and activate the trigger and fire the firearm. It is shown here in a right-handed configuration, but could be adapted to left hand, or even ambidextrous use. As an example of what's possible, as presented in this example, if a ledge or surface (108) were extruded down from the trigger system near where it would drop out of the trigger hole in the receiver, then the user could both push on the trigger with their right thumb on the left side of the grip, or move their index finger in from the right side of the grip to activate the trigger with their index finger from within the trigger guard area. FIGS. 197-201 show an assembly of a thumb activated push trigger with a transfer trigger bar, disconnector, and hammer.
FIGS. 202-206 show how a grip frame could be altered to compliment the thumb push trigger system. It has a shroud (110) that acts like a secondary trigger guard with an opening (111) that the long arm fits through so that the grip can continue to slide back and forth during the slam fire operations without the grip bumping the trigger itself. The user's thumb can be placed on ledge while also wholly or partially cover the opening from the rear such that each time the grip frame and/or unified stock body is pushed forward the thumb contacts push surface and activates the trigger without the need for a separate movement of the thumb itself. The slide lock catch release surfaces of the slam grip in this example could be used to lock the grip to the rear using the slide lock, but a new carve out locking feature (112) could be utilized to also lock the grip forward. In this case, it would be advantageous to lock the slam grip forward as opposed to rearward so that you could manually use your thumb to activate the thumb push trigger surface whereas if the grip were locked to the rear, the shroud would block access to the push trigger surface. An adjustable length of pull thumb trigger is a possibility to customize the fit for individual shooters.
FIGS. 207-218 show the possibility of an extended shroud (113) that could be placed on the thumb grip frame to further protect the thumb trigger from being activated by the accidental or unintentional intrusion of external objects including extending out the thumb rest ledge and extending the shroud opening forward and rearward and covering various sides of it to prevent intrusions. FIG. 211 near the center is shown from the left side, and projections are made from the middle outwards to show different views of the shroud.
The system may be purpose built as a novel firearm or may be a system or set of components to convert an existing semi-auto or self-loading firearm to use the invention system. The components of push triggers, sliding bodies, locks, limiters, and other components mentioned here that comprise the invention system and systems to allow semi-automatic firearms to be slam fired using major muscles as opposed to fine motor skills may be separable from each other. Major design parameters of the system were described here, but countless variations are possible. For instance, slam grip bodies could be designed around many types of needs for people with different disabilities, or the slam grip could be removed completely in favor or just slamming the stock directly. A removeable trigger guard containing a necessary pin hole for some examples of a push trigger was discussed and it relied on existing pin slots of an example receiver to install, however bolt on trigger guard bodies like it could achieve the same effect, or a component containing the new pin hole could just be welded or otherwise permanently affixed to an existing firearm.
The components of the system can be made from appropriate metal, polymer, and other materials, either machined, forged, molded, or fabricated with other appropriate manufacturing techniques.
Individual components need not be separate parts. Features could be combined into other parts that serve the same purpose, and could be made integral to the receiver frame instead of existing outside the frame or vice versa.
Rotating transfer triggers have been used, but they can be changed to also be directional transfer triggers. For instance the push trigger can be designed to be pushed which causes a directional movement such that the hammer or striker is mechanically released for firing.
Besides interacting with hammers or stikers strikers, the push triggers can also be used to activate an electric or electronic firing device or any other type of firing device. Rather than just a single transfer trigger, multiple transfer triggers could be utilized in the push or pull sequence.
