BACKGROUND OF THE INVENTION

1. Field of Invention

This invention relates to firearms and more particularly to devices for ejecting magazine cartridges from 22 caliber rifles.

2. Description of Related Art

The present invention relates generally to a .22 semi-automatic rifle magazine release. Particularly, the present invention relates to a device that when integrated into a Ruger 10/22 semi-automatic rifle, it allows for a quick ejection of the magazine.

The .22 semi-automatic rifle is very popular for target practice and for small-game hunting. One of the most common complaints about the .22 semi-automatic rifle is regarding the removal of the magazine to reload the weapon. Removing the magazine is often difficult and time consuming.

In order to reload the weapon, the magazine must be removed. With the conventional magazine release, the user must push the magazine latch with one hand and then wiggle the magazine with the other hand to remove it. This process is inconvenient and takes unnecessary time. For competition shooting it is necessary for the competitor to reload as fast as possible.

Often the user of a .22 semi-automatic rifle wears gloves when using the weapon. With the conventional magazine release it is difficult to grasp the magazine and wiggle it out. The user often needs to set the weapon down and remove his gloves prior to removing the magazine, and then put his gloves back on prior to using the weapon again. This causes inconvenience to the user who wants to continue shooting.

Therefore, there remains a need for a faster, quicker, and effective magazine release for the .22 semi-automatic rifle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 1 shows a trigger housing 1 for a firearm. The trigger housing 1 is preferably configured to the trigger housing for a 22 caliber rifle.

The trigger housing includes a variety of conventional components found in a conventional 22 trigger housing, such as those made by Ruger. This trigger housing includes a trigger 2 and a hammer 4, which is operated by the trigger 2. The housing also includes a magazine ejector lever 20 having a free end 22 and an engagement end 24. The trigger housing 1 further includes a plurality of pins, such as pins 15, 17 and 19, that extend from one side of the housing to the other. The pins hold internal components of the housing 1, such as the hammer 4 in place and/or allow them to rotate relative to the housing 1.

FIGS. 1-6 display a magazine ejection device 100 made in accordance with the present invention. The ejection device 100 includes a spring 102 and an actuator 110, as shown in FIG. 2. Note, the spring 102 is not shown in FIGS. 3 and 4 for clarity purposes.

The actuator 110 includes a main body having an action arm 120 and spring engagement member 130. The actuator 110 is preferably made of one integral piece of material. The engagement member 130 and the action arm 120 are preferably at about opposing ends of the actuator 110, as shown. The engagement member 130 includes a notch 132. The notch 132 is operably configured to receive an end of the spring 102.

Actuator 110 further includes an alignment slot 140 and portions 142 and 150. Slot 140 is defined by portions 142 and 150, as shown. Portion 150 is disposed along the length of the actuator between the action arm 120 and the engagement member 130. Portion 150 includes an edge 152, which is an opposing edge to the edge that forms a portion of the slot 140. Portion 150 further includes a bottom edge 154. Bottom edge 154 is angled relative to engagement member 130. The bottom edge 154 extends from a point 155, where it is adjacent to the engagement portion 130 to a point 156. Point 155 is relatively closer to the slot 140 than the point 156 and this difference creates the angled edge 154. The edge 154 is preferably angled so as to provide space within the housing 1 for the spring 102 when the device is in use as will be detailed further below.

The actuator 110 further includes leg 160 having a bottom edge 162. Leg 160 is preferably disposed adjacent the action arm 120 and spaced along the length of the actuator 110 from the portion 150. The leg 160, portion 150 and the portion of the action arm 120 that accounts for the spacing between the leg and the portion 150 defines a void 164 beneath the arm 120, as shown.

The actuator 110 preferably is substantially planar along its length, such that the action arm 120, leg 160 and portions 142 and 150 generally fall within the same plane. Engagement member 130 is preferably disposed substantially perpendicular to the other portions of the actuator 110, as shown in FIG. 4. The engagement member 130 in this embodiment is integral with the portion 150 and is made from the same material. However it should be appreciated that in other exemplary embodiments, the engagement member is not integral and is affixed to the actuator body by any conventional means, such as but not limited to welding, epoxy and the like.

FIGS. 5 and 6 illustrate the device 100 in operation. The device 100 is operably configured to assist with the ejection of a magazine 90, partially shown for clarity purposes, that is engaging a receiver of a rifle, not shown. FIG. 5 illustrates an engaged state, wherein the magazine is inserted in the rifle. FIG. 6 illustrates a disengaged state, wherein the magazine had just been disengaged.

It should be appreciated that in operation, it is the ejector lever 20 that holds the magazine in the engaged state of FIG. 5. Activation by the user of the ejector lever 20, enables the operation of the device and the switching of the states from engaged to disengaged. The engaged state is achieved again when another magazine or the same magazine is reinserted into the rifle such that the ejector lever 20 is activated so as to engage and hold the magazine in the engaged state again.

In this operation, it will be appreciated that ejection device 100 of the present invention acts to forcibly eject the magazine away from the rifle in a downward fashion as illustrated in FIG. 6. The amount of force exerted upon the magazine is determined by the spring 102 that is employed.

While in the engaged state, as shown in FIG. 5, the device 100 is exerting a downward force upon the magazine 90. The force is being generated by the spring 102 pulling upon the notch 132 of the engagement member 130 and hence the entire actuator 110 including the arm 120. The other end of the spring 102 engages the pin 19. The arm 120 is operably configured to engage a groove 92 of the magazine. However, even though the arm 120 is applying a downward force upon the magazine 90, the engagement end 24 of the ejector lever 20 is disposed under a stud 94 on the magazine 90 when in the engaged state. With the engagement end 24 under the stud 94, the magazine is prevented from being ejected from the rifle.

A spring 26 is disposed between an upper portion of the ejector lever 20 and an internal wall 30 of the housing. The spring 26 is biased to provided a force against the upper portion of the lever 20 to keep it from inadvertently disengaging the stud or tab 44 of the magazine 40. When the operator of the rifle desires to eject the magazine, the lever 20 is activated by moving the free end 22 of the lever 20 in the direction of arrow 2, as shown in FIG. 6. This causes the lever 22 to rotate about pin 17 in a counter clockwise direction and it also compresses spring 26. The user will have to apply enough force to the lever 20 to overcome the force applied to the lever 20 by the spring 26.

The disengaged state is achieved once the lever 20 rotates enough so that the end 24 is no longer disposed beneath the stud 94 of the magazine 90. At that moment, the device 100 of the present invention will still be applying a downward force upon the magazine (in the direction of arrows 3 and 4) and the magazine will be automatically ejected without the user having to pull or wiggle the magazine free from the firearm.

The actuator 110 translates downward when in operation and going between the engaged and disengaged states. The actuator translates upwards when in operation and going from the disengaged to the engaged state. The alignment slot 140 is operably configured to receive pin 15. As the actuator translates up and down, the pin 15 within the alignment slot 140 assists with keeping the actuator within the correct position within the housing during operation. The pin 15 stops the upward movement of the actuator when the pin engages the bottom of the slot 140. The trigger housing 1, includes an internal wall 30. Further edge 152 is operably configured to slide along the wall 30. It is preferable to have edge 152 slide along the wall 30 to provide stability to the movement of the actuator within the housing. The longer edge 152 is, the more stability it will provide. The dimensional length of the edge 152 is constrained by the internal limitations of the components of the trigger housing. The bottom edge 162 acts as a stop for the actuator 110. The bottom edge 162 limits the downward travel of the actuator 110 within the housing as the bottom edge 162 will not travel past a portion of the wall 30, as shown in FIG. 6. The spring 102 is a tension spring in this exemplary embodiment. It should be appreciated that in other exemplary embodiments the spring may be other types of spring, such as a torsional spring and arranged differently within the housing so long as it applies a spring bias against the actuator such that the actuator applies the downward force upon the magazine.

FIG. 6A displays such an embodiment. FIG. 6A shows the use of a torsional spring 102′ rather than the spring 102. The spring 102′ has legs 103 and 104. Spring 102′ is disposed about another pin 21, which extends through the housing. Leg 103 engages the engagement member 130 and leg 104 engages another pin 11, which extends through the housing. It should be appreciated that leg 104 could press against other components within the housing. With this arrangement, the torsional spring 102′ is biased such that the leg 103 applies a downward force against the actuator 110.

Referring now to FIGS. 7 and 8, wherein an ejection device 200 is shown. The device 200 is an alternative embodiment of an ejection device made in accordance with the present invention. The device 200 includes a spring 210 and a recess 220 within the trigger housing. The device 200 can be utilized in conjunction with the device 100 referenced above and as shown in FIGS. 7 and 8. However, it should be appreciated that in other exemplary embodiments, the device 200 is utilized without an additional ejector device similar to the device 100. Moreover, it should be appreciated that in this embodiment, the device 200 is disposed on a single side of the trigger housing. It should be appreciated however that in other exemplary embodiments, the device 200 is disposed on both sides of the trigger housing.

The spring 210 has first and second legs 212 and 214. The spring is disposed within the recess 220. Further, coils 216 of the spring 210 are disposed about the pin 15. It is preferred that the recess be of a depth that allows coils 216 to be flush with the end of pin 15. In this exemplary embodiment, the spring 210 is a torsional spring, wherein at least the end of second leg 214 is disposed against a wall of the recess 220 and at least the end of first leg 212 is disposed against the top surface of the magazine 90 when in the engaged state, as shown in FIG. 7. Preferably, the first leg 212 is curved downward to engage the magazine. Further, the second leg 214 is preferably completely disposed within the recess 220. The first leg 212 is of such a length that it extends out from the recess past the housing so as to be engageable with the magazine as shown in FIG. 7. The first and second legs 212 and 214 with their engagements against the magazine and the wall of the recess, respectively, are biased against one another so as to exert a downward force upon the magazine. The recess 220 has a shape to accommodate a portion of the spring 210. The recess 220 includes a coil recess portion 221 and a leg recess portion 223. The coil recess portion 221 is operably configured to receive the coils 216 and the leg recess portion 223 is operably configured to receive the second leg 214 as shown in FIGS. 7 and 8. With this arrangement, the first leg 212, which is not in the recess 220, is allowed to move along the trigger housing in a radial direction from a compressed stage in the engaged state (FIG. 7) to a less compressed stage in the disengaged state (FIG. 8). Further, the biased nature of the spring 210 pressing against the walls of the recess 220 and the coils 216 being disposed about the pin 15, keeps the spring 210 in position on the trigger housing and prevents it from becoming dislodged. In one exemplary embodiment, it is preferred that the first leg of the spring 210 be about 1.35 inches long and that the second leg be about 0.75 inches long. Further, in a preferred exemplary embodiment, the wire size of the spring 210 is about 0.041 inches in diameter. It is also preferred that that spring 210 have about three coils, and more preferably just one coil. It should be appreciated that the number of coils will depend upon the wire size used for the spring. In a preferred embodiment, the outside diameter of the coil is less than 0.312 inches in diameter and the inside diameter of the coil is greater and 0.2185 inches.

FIG. 7 illustrates the engaged state of the magazine and FIG. 8 shows the disengaged state. When the magazine is disengaged, the spring 210 will force the magazine down away from the firearm. Further, although in this exemplary embodiment, the magazine release mechanism is the mechanism discussed above with reference to device 100, other magazine release mechanisms can be utilized with device 200 including the release device that is standard from a conventional manufactured Ruger 10/22, or other after-market mechanisms.

It should be appreciated that the device 200 can be added to an existing trigger housing. The invention includes a method of modifying a trigger housing to include an ejection device made in accordance with this invention. The method of this invention will enable conventional or existing Ruger 10/22 firearms to be modified to include a spring loaded ejection mechanism. The method of the present invention includes acquiring a firearm. It is preferred that this step include acquiring an existing trigger housing having first and second sides, an internal cavity defined by the first and second sides, and a pin spanning the internal cavity.

The action end 820 is operably configured to engage and apply a force upon a magazine 890. The engagement member 830 is disposed adjacent an end of the spring 802. The engagement member 830 has a diameter that is larger than the diameter of the housing 803, such that the actuator will stay physically adjacent to the spring 802 and the housing 802 when the spring is in an expanded state when the magazine 890 is in a disengaged state. The magazine 890 is ejected from the receiver when an ejection lever is moved to disengage the magazine stud 894, similar to the embodiment for the device 100 discussed above. The device 800 acts basically as a spring-loaded plunger located within the receiver 809 of the firearm. As in the other embodiments, the firearm also includes a trigger housing 801. The device 800 is spring biased so as to apply a downward force upon the magazine 890. FIG. 16, shows the device 800 positioning state when the magazine 890 in a disengaged state.

Referring now to FIG. 17, wherein an ejection device 900 is shown. The device 900 is an alternative embodiment of an ejection device made in accordance with the present invention. The device 900 is similar to the device 100 referenced above, in that it includes a spring 902 and an actuator 910. The firearm includes, among other things, a trigger housing 901 and a receiver 909. The receiver 909 includes a spring housing 903. The spring housing in this embodiment is a void in the receiver 909 shaped to receiver the spring 902. The spring 902 is disposed in the spring housing 903. The spring 902 is different however as it is a compression spring rather than a tension spring. Further actuator 910 is similar to actuator 110 in that it includes an action arm 920, and an engagement member 930. The engagement member includes an orifice. The pin 915 is disposed through the orifice when the device is in use. Further, rather than translating in just the vertical direction, the actuator 910 in this embodiment rotates about the pin 915. The compression spring 902 is disposed above the actuator 910 and biased to exert a force upon the engagement portion 930 of the actuator 910 such that the actuator 910 will rotate counter clockwise about the pin when a magazine 990 is in a disengaged state. FIG. 17, shows the device 900 positioning state when the magazine 990 in a disengaged state.

Referring now to FIG. 18, wherein an ejection device 1000 is shown. The device 1000 is an alternative embodiment of an ejection device made in accordance with the present invention. The device 1000 is nearly identical to the device 900 shown in FIG. 17, and it includes identical components, as shown. The firearm includes a trigger housing 1001 and a receiver 1009. The device 1000 includes a spring 1002 and an actuator 1010 having an engagement member 1030, and action arm 1020. The receiver 1009 includes a housing 1003, which is operable configured to receive the spring 1002. The difference is that the device 1000 is disposed forward of a magazine 1090 rather than aft as with the device 900, relative to the barrel of the firearm. The device is also disposed within the receiver of the firearm, rather than the trigger housing. With this orientation difference, the actuator will rotate clockwise about the pin 1013 when the magazine is being disengaged. FIG. 18, shows the device 1000 positioning state when the magazine 1090 in a disengaged state.

Referring now to FIGS. 19-20, wherein an ejection device 1100 is shown from a right side. The device 1100 is an alternative embodiment of an ejection device made in accordance with the present invention. FIG. 19, shows the device 1100 positioning state when the magazine, not shown, in a disengaged state. The device 1100 is similar to the device 900 and it includes similar features and characteristics, such as the actuator 1110 rotating about a pin 1115 to eject the magazine. One difference between the embodiments is the spring. Spring 1102 is a tension spring rather than a compression spring and further, the spring 1102 is also disposed below the actuator 1110 rather than above it, relative to the firearm. As the magazine is inserted into the receiver (not shown), the actuator 1110 is rotated counter clockwise about pin 1115. This rotation of the actuator expands the spring 1102, making the tension spring apply a downward force upon the actuator 1110 at the engagement member 1130. The engagement member 1130 is disposed at a distance along the length of the actuator 1110 from the pin 1115, so that when the magazine is disengaged, the tension spring 1102 will pull the actuator, forcing it to rotate about the pin 1115 and hence the action arm 1120, of the actuator 1110, will apply a force upon the magazine forcing it to automatically eject from the receiver. The disengaged state of the magazine is shown in FIG. 19, wherein the actuator 1110 comes to rest against a pin 1133 in the housing. The pin 1133 acts as a stop to limit the radial movement of the actuator.

Referring now to FIGS. 21-22, wherein an ejection device 1200 is shown. The device 1200 is an alternative embodiment of an ejection device made in accordance with the present invention. FIG. 21, shows the device 1200 positioning state when the magazine, not shown, in a disengaged state. The device 1200 is very similar to the device 1100 and includes similar features and characteristics, including a tension spring 1202 and an actuator 1210. The actuator 1210 includes an engagement portion 1230, an action arm 1220. The actuator 1210 rotates about a pin 1215 when in use. One difference between the device 1200 and the device 1100 is the overall shape of the actuator 1210. Another difference is the inclusion of a loop section 1245 on the actuator 1210. The loop section 1245 is operably configured to be disposed about a pin 1233 and is shaped to allow for the rotation of the actuator 1210 about pin 1215. The width of the loop section 1245 is configured to just slightly greater than the diameter of the pin 1233. The length of the loop section is configured to be the desired radial translation of the actuator within the housing, not shown. The loop section 1245 will limit the radial translation of the actuator about the pin 1215.

Referring now to FIGS. 23-24, wherein an ejection device 1300 is shown. The device 1300 is an alternative embodiment of an ejection device made in accordance with the present invention. The ejection device 1300 includes a block 1380 a plurality of actuators 1310 and at least two springs 1302. The block is preferably plastic. Formed within the block are two holes or cavities 1382. A spring 1302 is disposed in each of the holes 1382. Actuator 1310 includes an action arm 1320 and an engagement member 1330. The action arm 1320 in this embodiment is a plunger. The engagement member 1330 is disposed against one end of one of the springs. An engagement member 1330 of a different actuator engages an opposing end of the same spring, so as to form pairs of plungers as shown. The diameter of the engagement member is preferably larger than the diameter of the hole 1382 so as to prevent the spring from escaping from the hole. The springs 1302 are preferably compression springs. The actuators and springs in this embodiment operate much like the plungers described above in connection with the ejection device 800. Attached to opposing sides of the block are conventional magazines 1390. A difference between this embodiment and the embodiment 800 is that the actuator and spring is located within the block and not the receiver.

Referring now to FIGS. 25-26, wherein an ejection device 1400 is shown. The device 1400 is an alternative embodiment of an ejection device made in accordance with the present invention. The device 1400 is similar to the device 1300 in that it includes a block 1480 for holding magazines 1490 on opposing sides of the block. However, rather than having the actuator and spring design as many of the embodiments above have, it has a spring 1410 and recess 1420 type design as many of the embodiments above have. The recess in this embodiment is a slot or hole for the spring to be fitted through. The spring 1410 is a biased wire, which acts like a torsion spring.

Referring now to FIG. 27, wherein an ejection device 1500 is shown. The device 1500 is an alternative embodiment of an ejection device made in accordance with the present invention. The device 1500 is and functions similar to the device 800, in that it includes a similar plunger type design of the actuator 1510 and spring 1502. In this embodiment a magazine 1590 includes an extended magazine 1598. A difference between this embodiment and the device 800 is that the ejection device 1500 is disposed in the extended magazine 1598 and not the receiver. Otherwise the ejection device functions in a similar manner.

While this invention has been described in conjunction with the specific embodiments outlined above, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, the preferred embodiments of the invention, as set forth above, are intended to be illustrative, not limiting. Various changes and combinations thereof may be made without departing from the spirit and scope of this invention.
