Description

FIELD OF THE INVENTION

[0001] This invention relates to the field of firearms, and more speciflcally to removable trigger-blocking devices.

BACKGROUND OF THE INVENTION

[0002] Firearm users often need a device with which to lock or guard the trigger on their gun. Such devices can prevent children from being able to access the trigger on the gun and accidentally or purposely shooting the gun. The devices also prevent the trigger from unexpectedly being pulled while the gun is stored or jostled around.

[0003] In the past, trigger locks or trigger guards have been used to perform this purpose. These devices consist of at least two separate pieces which are placed on either side of the trigger of the gun and then locked together into fixed position. Most present firearm trigger locks and guard devices consist of a pair of guard pieces, a locking bar, and a key.

[0004] These devices have disadvantages. For instance, if any of the parts of the device is lost, the device cannot be used and must be totally replaced. Moreover, if a key is lost, the device cannot be opened in a emergency. Furthermore, some trigger guards are only designed for a certain size gun, such as a pistol, a rifle, or a shotgun.

[0005] Thus, there is a need for a removable trigger guard that has a minimal number of separate pieces, that can be opened without a key, and that can fit onto a variety of firearms.

SUMMARY OF THE INVENTION

[0006] The present invention provides a removable trigger guard including a one-piece housing having a gap for situating the housing around the trigger of a gun, a lock member integrally and slidably coupled to the housing, and a lock mechanism attached to the housing for locking the lock member into a position partially within the gap.

[0007] In further embodiments, the housing includes a first guard member and a second guard member connected by a linking member having a fixedly sized gap therebetween. The locking mechanism is a combination lock. In another embodiment, the lock member is U-shaped, having a first shaft with a latching section and a second shaft parallel to the first shaft.

[0008] The present invention provides a removable trigger guard that has a minimal number of removable, separate pieces so that it can be attached and removed from a gun without losing any parts. In one embodiment, the removable trigger guard includes a combination lock and therefore can be opened without a key, thus providing a complete one-piece mechanism. The present invention also provides a removable trigger guard that can interchangeably fit onto a variety of firearms.

DESCRIPTION OF PREFERRED EMBODIMENTS

[0014] In the following detailed description of the preferred embodiments, reference is made to the accompanying drawings that form a part hereof, and in which are shown by way of illustration specific embodiments in which the invention may be practiced. It is understood that other embodiments may be utilized and structural changes may be made without departing from the scope of the present invention.

[0015] The leading digit of reference numbers appearing in the Figures generally corresponds to the Figure number in which that component is first introduced, such that the same reference number is used throughout to refer to an identical component which appears in multiple Figures.

[0016] FIGS. 1-5 show an embodiment of a removable trigger guard 100 according to the present invention. FIG. 1 shows removable trigger guard 100 in position attached to an exemplary gun 110. As will be clear from the following description, trigger guard 100 can also be interchangeably used to block the access to the triggers on an assortment of guns such as rifles, shotguns, and/or pistols. Trigger guard includes a housing 103. Housing 103 has a one-piece, unitary structure when assembled, as shown in FIG. 2. Housing 103 has an approximate rectangle shape with a rounded portion disposed on one of its sides. The shape of removable trigger guard 100 and its rounded portion are adapted to cover and block access to a trigger 211 of gun 110. The shape is larger than the size of the gun's trigger guard section 210. In the present embodiment, the trigger guard is sized so that it will cover the trigger on a large gun such as a shotgun and also will cover the trigger of a relatively smaller gun such as a pistol without being excessively large.

[0017] Housing 103 includes an integral first guard member 220 and an integral second guard member 230. First guard member 220 and second guard member 230 are separated by a gap 240, which runs through a central section of housing 103. Gap 240 is sized to permit housing 103 to be disposed around trigger 211 so that first guard member 220 and second guard member 230 each block access to trigger 211 on the side they are disposed on.

[0018] First guard member 220 and second guard member 230 are connected by a linking member such as a crossbar 208 that permanently links the guard members after guard is assembled. In this embodiment, crossbar 208 has a hollow cylindrical shape and extends from first guard member 220 to second guard member 230 at an attaching hole 405. Removable trigger guard 100 can be assembled by attaching crossbar 208 to second member 230 by means of a threaded attachment, friction fitting, glue, or welding. Crossbar 208 provides a unitary structure for housing 103 while preventing the guard members 220 and 230 from coming apart. Alternatively, a linking member such as a hinge or other permanent connector can be used to connect guard members 220 and 230. This unitary structure allows removable trigger guard 100 to be disposed around the gun's trigger guard section 210 with crossbar 208 on the outside of trigger guard section 210 of the gun and a section of a lock post or lock member 201 on the inside of trigger guard section 210 of the gun. Removable trigger guard 100 can be attached to the gun without having to add or remove any pieces therefrom. The one-piece structure provides that no parts or members of trigger guard 100 can be misplaced when using the device.

[0019] Removable trigger guard 100 also includes lock post or lock member 201. Lock member 201 is slidably situated within housing 103. As shown in FIG. 4, lock member 201 has a first, or open, position such that lock member 201 is not within gap 240. This permits housing 103 of removable trigger guard 100 to be freely removed from and/or positioned around gun trigger guard section 210. In this embodiment, lock member 201 is forced into the first, or open, position by a forcing means such as a spring 301, which is located between housing 103 and lock member 201.

[0020] As shown in FIG. 3, lock member 201 has a second, or closed, position such that a portion of lock member 201 is at least partially within gap 240. When in this position, housing 103 remains firmly attached to gun 110 and cannot be pulled off in a direction along the length of the gun.

[0021] In this embodiment, lock member 201 is approximately U-shaped. It includes a first shaft 402 having a holding or locking section such as latching section 403 and a second shaft 401 which is slightly shorter than the first shaft. First shaft 402 is disposed to be slidably positioned within crossbar 208 while second shaft goes through a hole 404 in first guard member 220.

[0022] Linking member or crossbar 208 has a notch or slit 206 running down at least one side of the crossbar. A post 207 is attached to a section of first shaft 402. Post 207 is slightly longer than the diameter of crossbar 208 so that it catches against slit 206, causing lock member 201 to be retained in position within the crossbar. Those skilled in the art will recognize that other shapes for the lock member can be utilized as long as the lock member provides a locking function and is integrally coupled to the housing. Moreover, lock member 201 could be held in position by other catching means. For example, an outer retaining ring can be attached to an outer section of housing 103 to retain lock member 201 from falling out of the housing. The important thing is that the lock member forms an integral structure with the housing so that no parts of removable trigger guard 100 need be removed when attaching it or removing it from a gun.

[0023] Removable trigger guard 100 also includes a locking mechanism 104, such as a combination lock, attached to housing 103 for locking lock member 201 into the closed position. If a combination lock is employed, the complete trigger guard is a one-piece unit without a key that can be lost. Such a design greatly reduces the chances of rendering the trigger guard useless from the loss of only a part of it. Alternatively, the locking mechanism can include a key lock. This would mean that the unitary trigger guard 100 would only have to rely on one separate part that could get lost.

[0024] In this embodiment, locking mechanism 104 is a conventional combination lock sandwiched between a first section 231 and a second section 232 that comprise second guard member 230. Those skilled in the art will appreciate that many variations of combination locks can provide the same function of providing a locking mechanism that does not need a separate key.

[0025] Locking mechanism 104 includes a holding or latching section 408 for engaging with opposing lock member latching section 403 when lock member latching section 403 is pushed into contact with latching section 408. Locking mechanism 104 also includes a lockshaft 407 located beneath latching section 408. Lockshaft 407 includes three grooves 410-412 running around a surface of the lockshaft. A spring 406 is disposed around lockshaft 407 for forcing lockshaft 407 and latching section 408 in an axial direction against lock member latching section 403. A locking wheel mechanism 420 encircles lockshaft 407. Locking wheel mechanism 420 includes three combination indexing wheels 202-204. Each indexing wheel 202-204 needs to be turned to a correct number for lockshaft 407 to become disengaged from within locking wheel mechanism 420. A set/release button 102 is disposed under locking wheel mechanism 420. When set/release button 102 is pressed the user can turn index wheels 202-204 to their proper positions. When not pressed, set release button 102 keeps pressure on the wheels so that they will not turn unexpectedly.

[0026] A latch releasing means such as a button 101 is also slidably disposed within housing 103. Button 101 is adapted for releasing lock member 201 from the closed position to the open position. When locking mechanism 104 is in a locked state, button 101 cannot be depressed and the trigger guard 100 stays in a locked position. When locking mechanism 104 is in an unlocked state, button 101 can be depressed. This forces latching section 408 to disengage from lock member latching section 403. Spring 301 forces lock member 201 out of gap 240 and removable trigger guard 100 can be removed from the gun. This provides that even if the locking mechanism 104 is unlocked, the lock member 201 will not spring loose into an open position until button 101 is pushed. This allows the guard to be grasped firmly before it is released from its locked position so that it will not be lost or dropped while releasing it.

[0027] Second section 232 of second guard member 230 includes a cavity 205 for receiving a portion of first shaft 402 when it is in the closed position. Second section also includes three slits for exposing indexing wheels 202-204 so that a user has access to them to unlock the trigger guard.

[0028] To put removable trigger guard 100 onto a gun, a user opens it to an open position as shown in FIG. 4 by pushing button 101. The device is then placed around the trigger guard section 210 of the gun as shown in FIG. 1. The user then presses on the outer end of lock member 201 until second shaft 401 is substantially within gap 240 and latching section 403 of first shaft 402 has become engaged with the latching section 408 of lock mechanism 104, as shown in FIG. 3. To remove removable trigger guard 100, the user dials the combination of the lock mechanism and then depresses button 101. Spring 301 forces lock member 201 into an open position, and the device can be removed from around the trigger guard section of the gun.

[0029] The present invention provides a removable trigger guard that has a minimal number of removably separate pieces that need to be attached and/or removed from a gun. In one embodiment, the removable trigger guard includes a combination lock and therefore can be opened without a key, thus providing a one-piece mechanism. The present invention also provides a removable trigger guard that can interchangeably fit onto a variety of firearms.
