DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(8) The following description is disclosed to enable any person skilled in the art to make and use the present invention. Preferred embodiments are provided in the following description only as examples and modifications will be apparent to those skilled in the art. The general principles defined in the following description would be applied to other embodiments, alternatives, modifications, equivalents, and applications without departing from the spirit and scope of the present invention.

(9) Referring to FIGS. 1 to 4 of the drawings, a universal mounting assembly for a pistol is illustrated, wherein the pistol, which comprises a pistol armrest 1, can be embodied as a hand gun such as, Glock, or a rifle such as CZ Scorpion Evo 3. The universal mounting assembly comprises a connecting extension 10 and a universal mounting device.

(10) The connecting extension 10, which has an elongated structure, has a front end 11 adapted for detachably coupling to the pistol armrest 1 of the pistol. Accordingly, the front end 11 of the connecting extension 10 has a threaded structure rotatably coupled to the pistol armrest 1, such that the connecting extension 10 is rearwardly extended from the pistol. Preferably, the connecting extension 10 has a circular cross section to have a uniform outer diameter size. It is worth mentioning that the connecting extension 10 can be a part of the pistol, wherein the front end 11 of the connecting extension 10 is designed to have a particular size in order to couple the connecting extension 10 to the pistol armrest 1 of the pistol.

(11) As shown in FIGS. 1 to 4, the universal mounting device comprises a buttstock body 20 and a locking mechanism 30. The universal mounting device is embodied as a universal pistol brace or a universal pistol stabilizer so as to allow the user to hold the pistol stably.

(12) The buttstock body 20 has an elongated holding channel 201, wherein the connecting extension 10 is slidably coupled at the holding channel 201 of the buttstock body 20 at a position that the front end 11 of the connecting extension 10 is frontwardly extended from the buttstock body 20. Accordingly, a diameter size of the holding channel 201 is slightly larger than the diameter size of the connecting extension 10, such that the connecting extension 10 can be freely slid along the holding channel 201. Preferably, a distance of the holding channel 201 is shorter than a length of the connecting extension 10. It is worth mentioning that the diameter size of the holding channel 201 is adjustable.

(13) The locking mechanism 30 is provided at the buttstock body 20 to selectively adjust the diameter size of the holding channel 201 thereof, wherein when the connecting extension 10 is slid along the holding channel 201, the locking mechanism 30 is actuated to reduce the diameter size of the holding channel 201 to lock up at least a portion of the connecting extension 10 at the holding channel 201. In other words, the buttstock body 20 is moved between an unlocked position and a locked position. At the unlocked position, the connecting extension 10 is able to freely slide along the holding channel 201 to selectively adjust a protruding length of the front end 11 of the connecting extension 10 being frontwardly extended out of the buttstock body 20. At the locked position, the diameter size of the holding channel 201 is reduced to lock up the connecting extension 10 at the holding channel 201.

(14) According to the preferred embodiment, the buttstock body 20 comprises a tubular holding member 21 defining the holding channel 201 therealong. The holding member 21 comprises a stationary edge 211 integrally extended from the buttstock body 20 and a free edge 212 spacedly extended along the stationary edge 211 side-by-side to define an adjustment clearance 213 therebetween. The holding member 21 generally has a C-shaped cross section, wherein the holding member 21 further comprises a circular shaped channel member 214 that the stationary edge 211 and the free edge 212 are extended along two opening edges of the channel member 214 of the holding member 21. Preferably, a thickness of the stationary edge 211 is different from a thickness of the free edge 212. In particularly, the stationary edge 211 is thicker than the free edge 212. Accordingly, at the unlocked position, the adjustment clearance 213 should be wide enough for configure the diameter size of the holding channel 201 for allowing the connecting extension 10 being freely slid along the holding channel 201. At the locked position, the free end 212 of the holding member 21 toward the stationary edge 211 thereof that the adjustment clearance 213 should be narrow enough for reducing the diameter size of the holding channel 201 to tightly press an inner wall of the holding channel 201 at an outer wall of the connecting extension 10.

(15) As shown in FIG. 5, each of the stationary edge 211 and the free edge 212 are formed as two elongated edge members spacedly extended side-by-side to define the adjustment clearance 213 therebetween, wherein the adjustment clearance 213 is embodied as an elongated gap between the stationary edge 211 and the free edge 212.

(16) According to the preferred embodiment, the locking mechanism 30 is actuated to press the free end 212 of the holding member 21 toward the stationary edge 211 thereof to reduce the diameter size of the holding channel 201 so as to lock up at least a portion of the connecting extension 10 at the holding channel 201. It is worth mentioning that when the free end 212 of the holding member 21 is pressed toward the stationary edge 211 thereof, a width of the adjustment clearance 213 is reduced, such that the diameter size of the holding channel 201 will be substantially reduced. Therefore, the inner wall of the holding channel 201 is tightly pressed at the outer wall of the connecting extension 10, i.e. an outer circumferential wall thereof, so as to lock up the connecting extension 10 at the holding channel 201.

(17) As shown in FIGS. 2 to 4, the holding member 21 comprises two spaced apart holding rings 215 to define a holding window 216 therebetween. Particularly, the holding rings 215 are constructed to form the channel member 214. The stationary edge 211 is integrally extended from two corresponding ends of the holding rings 215 while the free edge 212 is integrally extended from another two corresponding ends of the holding rings 215. It is worth mentioning that when the free end 212 of the holding member 21 is pressed toward the stationary edge 211 thereof to reduce the diameter size of the holding channel 201, the inner wall of the holding channel 201 is tightly pressed at the outer wall of the connecting extension 10. Therefore, by configuring two spaced apart holding rings 215, a contact area between the inner wall of the holding channel 201 and the outer wall of the connecting extension 10 will be reduced to reduce the pressing pressure against the connecting extension 10 so as to prevent any damage of the connecting extension 10 and/or the holding member 21. It is worth mentioning that the connecting extension 10 can still be tightly locked at the holding channel 201 via the holding rings 215. It is worth mentioning that the buttstock body 20 is able to fit different diameter sizes of the connecting extensions 10 for different pistols by selectively adjusting the diameter size of the holding channel 201 to fit the diameter size of the connecting extension 10.

(18) According to the preferred embodiment, the buttstock body 21 comprises a stock base 217, a front retention member 218 having a front channel 202 and a rear retention member 219 having a rear channel 203.

(19) The stock base 217 has a triangular shape and is arranged for biasing against a user's shoulder during a shooting operation of the pistol. The holding member 21 is upwardly extended from the stock base 217 at a position that the stationary edge 211 of the holding member 21 is integrally and upwardly extended from the stock base 217.

(20) Accordingly, the front and rear retention members 218, 219 are two tubular members to define the front and rear channels 202, 203 therewithin respectively. Preferably, a diameter size of each of the front and rear channels 202, 203 are slightly larger than the diameter size of the connecting extension 10, such that the connecting extension 10 can be freely slid along the front and rear channels 202, 203.

(21) The front and rear retention members 218, 219 are integrally and upwardly extended from the stock base 217, wherein the front and rear channels 202, 203 are coaxially aligned with each other. Particularly, the front and rear retention members 218, 219 are integrally and upwardly extended from front and rear portions of the stock base 217 respectively, wherein the holding member 21 is supported between the front and rear retention members 218, 219. Accordingly, the stationary edge 211 of the holding member 21 is integrally and upwardly extended from the stock base 217 between the front and rear retention members 218, 219 at a position that the holding channel 201 is aligned between the front and rear channels 202, 203, such that the connecting extension 10 is slid along the front and rear channels 202, 203 and is tightly locked at the holding channel 201. In other words, when the connecting extension 10 is slid along the front channel 202, the holding channel 201, and the rear channel 203, front and rear portions of the connecting extension 10 are received within the front and rear channels 202, 203 while a mid-portion of the connecting extension 10 is locked within the holding channel 201. Therefore, the connecting extension 10 can be securely and stably coupled at the buttstock body 20.

(22) According to the preferred embodiment, the locking mechanism 30 comprises at least a first locking slot 31 formed at the stationary edge 211 of the holding member 21, at least a second locking slot 32 formed at the free edge 212 of the holding member 21 to coaxially align with the first locking slot 31, and an actuation locker 33 extended to the first locking slot 31 through the second locking slot 32 to move the free end 212 of the holding member 21 toward the stationary edge 211 thereof.

(23) As shown in FIGS. 2 to 4, two first locking slots 31 are spacedly formed at the stationary edge 211 of the holding member 21 and are positioned below two corresponding ends of the holding rings 215. Correspondingly, two second locking slots 32 are spacedly formed at the free edge 212 of the holding member 21 and are positioned below another two corresponding ends of the holding rings 215. Two actuation lockers 33 are extended through the second locking slots 32 to the first locking slots 31 respectively in order to adjust the diameter size of the holding channel 201 via the adjustment clearance 213.

(24) As shown in FIG. 5, the actuation locker 33 comprises a locking nut 331 positioned at the stationary edge 211 of the holding member 21 and a locking bolt 332 extended from the second locking slot 32 through the first locking slot 31 to rotatably engage with the locking nut 331 so as to press the free edge 212 of the holding member 21 to the stationary edge 211 thereof. In other words, an outer threaded portion of the locking bolt 332 is rotatably engaged with an inner threaded portion of the locking unit 331 to selectively control the width of the adjustment clearance 213 so as to selectively adjust the diameter size of the holding channel 201. The locking bolt 332 has an elongated bolt body and an enlarged pressing head, wherein the bolt body of the locking 332 is extended through the first and second locking slots 31, 32 to engage with the locking nut 331 until the pressing head of the locking bolt 332 is pressed against the free edge 212 of the holding member 21. It is worth mentioning that the locking bolt 332 has a non-circular tool slot formed at the pressing head, wherein a tool T is used for engaging with the tool slot in order to drive the locking bolt 332 to rotate.

(25) Accordingly, the actuation locker 33 further has a nut cavity 333 indently formed at the stationary edge 211 of the holding member 21 to coaxially align with the first locking slot 31, wherein the locking nut 331 is received in the nut cavity 333 to engage with the locking bolt 332. In one embodiment, two nut cavities 333 are formed at the stationary edge 211 of the holding member 21 below two ends of the holding rings 215, wherein two locking nuts 331 are received in the nut cavities 333 to engage with the locking bolts 332 respectively. It is worth mentioning that the nut cavity 333 has a non-circular shape corresponding to the shape of the locking nut 331, such that when the locking unit 331 is disposed in the nut cavity 333, the locking unit 331 cannot be rotated within the nut cavity 333.

(26) Correspondingly, the actuation locker 33 further has a bolt cavity 334 indently formed at the free edge 212 of the holding member 21 to coaxially align with the second locking slot 32, wherein the pressing head of the locking bolt 332 is received in the bolt cavity 334 when the locking bolt 332 is engaged with the locking bolt 332. In one embodiment, two bolt cavities 334 are formed at the free edge 212 of the holding member 22 below two ends of the holding rings 215, wherein two pressing heads of the locking bolts 332 are received in the bolt cavities 334 respectively. It is worth mentioning that the bolt cavity 334 has a circular shape corresponding to the shape of the pressing head of the locking bolt 332.

(27) FIG. 6 illustrates an alternative mode of the locking mechanism 30A which comprises at least a first locking slot 31A formed at the stationary edge 211 of the holding member 21, at least a second locking slot 32A formed at the free edge 212 of the holding member 21 to coaxially align with the first locking slot 31A, and an actuation locker 33A extended to the first locking slot 31A through the second locking slot 32A to move the free end 212 of the holding member 21 toward the stationary edge 211 thereof.

(28) Accordingly, the actuation locker 33A comprises a locking bolt having an outer threaded portion extended from the second locking slot 32A to rotatably engage with an inner threaded portion of the first locking slot 31A. Preferably, the actuation locker 33A is a hand screw that no tool is required for driving the actuation locker 33A, such that the user is able to rotate the actuation locker 33A by hand. The differences between the locking mechanism 30 and the locking mechanism 30A are that, in FIG. 5, no inner threaded portion is formed each of the first and second locking slots 31, 32, wherein the locking bolt 331 is engaged with the locking nut 332 to selectively adjust the diameter size of the holding channel 201. In FIG. 6, the inner threaded portion is only formed at the first locking slot 31A, wherein the locking bolt of the actuation locker 33A is engaged with the first locking slot 31A without the locking nut to selectively adjust the diameter size of the holding channel 201.

(29) FIG. 7 illustrates a method of mounting the universal mounting device to the pistol, comprising the following steps.

(30) (1) Couple the front end 11 of the connecting extension 10 to a rear end of the pistol at the armrest 1 thereof.

(31) (2) Slide the connecting extension 10 along the holding channel 201 of the buttstock body 20. In one embodiment, the connecting extension 10 is slid from the front channel 202 to the rear channel 203 through the holding channel 201.

(32) (3) Lock up at least a portion of the connecting extension 10 at the holding channel 201 via the locking mechanism 30 by reducing the diameter size of the holding channel 201 in order to tightly press the inner wall of the holding channel 201 at the outer wall of the connecting extension 10.

(33) It is worth mentioning that the connecting extension 10 can be coupled to the pistol after the connecting extension 10 is locked at the buttstock body 20 via the locking mechanism 30. Preferably, the connecting extension 10 is coupled to the pistol before the connecting extension 10 is locked at the buttstock body 20.

(34) According to the step (3), in one embodiment, the locking nut 331 is placed at the stationary edge 211 of the holding member 21 and is disposed within the nut cavity 333. Then, the locking bolt 332 is extended through the first and second locking slots 31, 32 to engage with the locking nut 331 until the pressing head of the locking bolt 332 is received in the bolt cavity 334. Through the engagement between the locking nut 331 and the locking bolt 332, the adjustment clearance 213 is adjustably reduced to adjustably reduce the diameter size of the holding channel 201. Therefore, the inner wall of the holding channel 201 is tightly pressed at an outer wall of the connecting extension 10 to lock up the connecting extension 10 at the holding channel 201

(35) Alternatively, the hand screw of the actuation locker 33A can be extended through the second locking slot 32A to rotatably engage with the first locking slot 31A to adjustably reduce the diameter size of the holding channel 201.

(36) One skilled in the art will understand that the embodiment of the present invention as shown in the drawings and described above is exemplary only and not intended to be limiting.

(37) It will thus be seen that the objects of the present invention have been fully and effectively accomplished. The embodiments have been shown and described for the purposes of illustrating the functional and structural principles of the present invention and is subject to change without departure from such principles. Therefore, this invention includes all modifications encompassed within the spirit and scope of the following claims.
