Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention [0001]
  • The present invention relates to a fixture for a pistol accessory, and in particular to a sliding sheath type fixture for securing a pistol accessory to a pistol. [0002]
  • 2. Description of the Prior Art [0003]
  • The conventional fixing rack for a pistol accessory is normally used to secure a pistol accessory on the trigger guard of a pistol. Referring to FIGS. 1 and 2, a conventional fixing rack comprises a fixing base [0004] 12, a fixing sheath 16 and a connecting plate 14. The fixing base 12 has an L-shaped base plate 122 and an arc body 124 that are connected by a bridge element 126. A space 123 is disposed between the L-shaped base plate 122 and the arc body 124. A plurality of threaded holes 125 are positioned at the flank sides of the L-shaped base plate 122 and the arc body 124, and another threaded hole 127 adapted to receive a short bolt 128 is also positioned at the short edge of the L-shaped base plate 122. A plurality of round holes 145, aligned with the threaded holes 125 that are positioned at the flank sides of the L-shaped base plate 122 and the arc body 124, are positioned on the connecting plate 14 in order to connect and fix the connecting plate 14 to the fixing base 12. A circular through hole 162, having a longitudinally cut groove 164 therein, is disposed in the fixing sheath 16, with one end of the cut groove 164 transitioning to a curved groove 166 that is perpendicular to the cut grove 164. A plurality of threaded holes 168 and 167 are positioned along the bottom of the fixing sheath 16. A laser sight (not shown) can be inserted in the circular through hole 162, and a bolt 184 can be screwed into the hole 168 to secure the laser sight tightly in the circular through hole 162 because the existence of the cut hole 164 allows the cylindrical body of the sheath 16 to be flexed inwardly to clamp the laser sight when the bolt 184 is screwed tightly inside the hole 168. In addition, the sheath 16 can be secured to the fixing base 12 by securing bolts 182 through the holes 167 and into aligned holes 125 on the L-shaped base plate 122.
  • In use, the trigger guard [0005] 25 of a pistol 20 is inserted into the space 123 of the fixing base 12, and then the connecting plate 14 is secured to the L-shaped base plate 122 via the bolts 182, the openings 145 and the holes 125. After that, the short bolt 128 is screwed into the hole 127 to press tightly against the trigger guard 25 so that the arc body 124 and the short bolt 128 can clamp the trigger guard 25 so as to prevent the fixing rack from shaking.
  • Unfortunately, the fixing base [0006] 12 of the conventional fixing rack described above is locked on the trigger guard 25 of the pistol 20. This makes it not only inconvenient to assemble and disassemble, but also limits the space inside the trigger guard, hindering a user's finger during operation of the pistol. Additionally, not all front ends of trigger guards of pistols are perpendicular and smooth, so the axial line of the fixing base 12 will deviate from the sight line, making it difficult obtain an accurate aim.
  • SUMMARY OF THE INVENTION
  • It is an object of the present invention to provide a fixture for a pistol accessory that is easy to assemble and disassemble from the pistol. [0007]
  • It is another object of the present invention to provide a fixture for a pistol accessory that assures that the axial line of the fixture is aligned with the sight line of the pistol. [0008]
  • It is yet another object of the present invention to provide a fixture for a pistol accessory that can be tightly secured to the pistol during use to prevent the fixture from shaking or misalignment. [0009]
  • The objects of the present invention can be accomplished by providing a fixture for attaching a pistol accessory to a pistol. The fixture has a seat having a holding hole for retaining the pistol accessory, the seat having a generally U-shaped body with two flank sides connected by a bottom surface, and with each flank side having an inner surface and a fixing hole. The seat further includes a sliding track disposed on the inner surface of each flank side, with each sliding track slidable along one of the longitudinal grooves along the bottom edge of the pistol barrel. The fixture further includes a fixing rod extending through the fixing holes in the two flank sides, and an elastic mechanism provided adjacent the bottom surface of the seat and engaging the fixing rod to bias the fixing rod into a transverse groove at the bottom edge of the pistol when the fixture is attached to the pistol.

  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • FIGS. 3, 4, [0019] 5A and 5B illustrate one embodiment of a fixing rack 30 according to the present invention, which includes a seat 32, a fixing rod 36 and an elastic mechanism 34.
  • The seat [0020] 32 has a holding hole 322 at its lower side for receiving a pistol accessory 40. A U-shaped sliding sheath 324 is disposed at the upper side of the seat 32, and a sliding track 325 is disposed at each inner side of each flank side 321 of the sliding sheath 324, and adapted to be inserted into a sliding groove at the bottom edge of a pistol barrel. A through fixing hole 326 is provided at each flank side 321 of the seat 32. The fixing rod 36 is positioned through the fixing holes 326 of the seat 32 and can be moved up and down inside the fixing holes 326. The elastic mechanism 34 is installed at the bottom of the sliding sheath 324 to support the fixing rod 36 and to supply an upward elastic force so as to keep (i.e. bias) the fixing rod 36 at an upper position inside the fixing holes 326 without the need to exert any external force. Therefore, referring to FIGS. 6A-6B, after the sliding tracks 325 are wedged into the longitudinal grooves 52 at the bottom of the pistol barrel, the fixing rod 36 can be moved upward to be seated into a transverse groove 54 of the pistol 50 to secure the fixing rack 30 to the pistol 50. The elastic force of the elastic mechanism 34 maintains and biases the fixing rod 36 securely in the transverse groove 54. To remove the fixing rack 30 from the pistol 50, the fixing rod 36 is pressed downwardly to counter the elastic force of the elastic mechanism 34, and the sliding sheath 324 (i.e. the tracks 325) can be slid off the longitudinal grooves 52 of the pistol 50.
  • An inclined plane [0021] 362 may be provided at the inner side of the fixing rod 36, so that the inclined plane 362 can easily slide up or down into or out of the transverse groove 54 when either an upward or downward force is applied to the fixing rod 36. In addition, a two-sided or L-shaped wedging surface 364 can be positioned at the outer side of the fixing rod 36 and adapted to be seated inside the transverse groove 54 to more effectively secure the fixing rod 36 inside the transverse groove 54 when the fixing rack 30 is secured to the pistol 50. A groove 366 may also be disposed at the lower side of the fixing rod 36 opposite from the wedging surface 364, and is adapted to allow the elastic mechanism 34 to be wedged and fixed therein to prevent the fixing rod 36 from sliding inside the fixing holes 326.
  • The elastic mechanism [0022] 34 can be provided in the form of elastic plates or springs. In addition, another elastic element may also be installed at the bottom of the sliding sheath 324 to prop against the bottom of the pistol barrel after the fixing rack 30 is secured to the pistol 50 so as to supply a second fulcrum, to prevent the fixing rack 30 from shaking even if a gap exists between the sliding sheath 324 and the bottom edge of the pistol barrel. In this embodiment of the present invention, a fixing elastic plate 342 and a supporting elastic plate 344 are provided on the elastic mechanism 34. The fixing elastic plate 342 supports the fixing rod 36 by providing an elastic force to bias the fixing rod 36 upwardly, and the supporting elastic plate 344 provides the function of the second fulcrum. A longitudinal groove 328, corresponding to the configuration of the elastic mechanism 34, is disposed at the bottom of the sliding sheath 324 so as to retain and secure the elastic mechanism 34 therein. The elastic mechanism 34 can be secured to the groove 328 by a threaded bolt 346 that can be screwed into aligned holes 348 (on the elastic mechanism 34) and 323 (in the groove 328).
  • A clamping ring [0023] 38 can also be provided at a front end of the seat 32 of the fixing rack 30. The clamping ring 38 has a longitudinal slot 386, and a threaded hole 382 is provided through each of the two flank sides of the slot 386 in the body of the seat 32, the two holes 382 being aligned with each other and extending transverse to the slot 386. The pistol accessory 40 can be inserted into the holding hole 322 of the seat 32, and then secured in the holding hole 322 by screwing a bolt 384 through the holes 382 to bring the holes 382 closer together (i.e., reducing the width of the slot 386) so as to clamp the clamping ring 38 against the pistol accessory 40.
  • FIGS. 6A and 6B illustrate how the fixing rack [0024] 30 can be mounted on to the pistol 50. The sliding tracks 325 of the sliding sheath 324 are slid on to the longitudinal grooves 52 of the pistol 50 until the fixing rod 36 is biased into the transverse groove 54 and secured therein. To dismount the fixing rack 30 from the pistol 50, the fixing rod 36 is pressed down to release the fixing rod 36 from the transverse groove 54, and then the fixing rack 30 can be slid forwardly out of the pistol 50. Since the longitudinal grooves 52 are disposed along the bottom edge of the pistol barrel and are parallel thereto, the axial line of the fixing rack 30 coincides with the axial line of the pistol barrel so that the laser sight line can be consistently maintained with respect to the axial line of the fixing rack 30.
  • As indicated above, the present invention uses a sliding sheath [0025] 324 and a biased fixing rod 36 to mount a fixing rack 30 onto a pistol 50, enabling a pistol accessory 40 to be mounted on and dismounted from a pistol 50 quickly and conveniently.
