Abstract

A mount adapter device is disclosed which utilizes a spring-loaded push system that employs a dual locking mechanism to releasably, consistently, and securely lock accessories to a weapon accessory rail. The mount adapter device generally includes a first base member, a second base member, a push rod member, and a resilient member. The push rod member slidably connects the first base member and the second base member. The first base member is linearly slidable into engagement with the second base member in a first direction, and the second base member is linearly slidable into engagement with the first base member in a second direction which is opposite the first direction. The first base member includes a first clamping member for engaging one edge of the rail. The second base member includes a second clamping member for engaging an opposite edge of the rail. The resilient member provides a spring force and is arranged to force the first clamping member to move in the first direction into locking engagement with the first edge of the rail while simultaneously forcing the second clamping member to move in the second direction into locking engagement with the second edge of the rail. A knob on the push rod member may be rotated down the push rod member to provide the device with a second locked position.

Claims

1. A mount adapter device for releasably attaching an accessory to a rail attached to a structure, said rail including a plurality of mounting projections extending perpendicular along a longitudinal axis of the rail and separated by a plurality of transverse grooves spaced along the longitudinal axis of the rail, each of said mounting projections including an upper mounting surface and opposite transverse edges defining first and second inclined proximal surfaces on opposite sides of the upper mounting surface, a first inclined distal surface adjacent to said first inclined proximal surface, and a second inclined distal surface adjacent to said second inclined proximal surface, said mount adapter device comprising:

a base including a first base member and a second base member, said first base member being linearly slidable into engagement with the second base member in a first direction, said second base member being linearly slidable into engagement with the first base member in a second direction which is opposite said first direction;

said first base member including a first clamping member for engaging a first edge of the rail; and

said second base member including a second clamping member for engaging a second edge of the rail which is opposite said first edge;

a push rod member slidably connecting said first base member to said second base member; and

a resilient member being received around said push rod member, said resilient member providing a spring force and arranged to force the first clamping member to move in said first direction into locking engagement with the first edge of the rail while simultaneously forcing the second clamping member to move in said second direction into locking engagement with the second edge of the rail.

2. The mount adapter device according to claim 1, wherein said base further includes an upper portion configured to receive and retain said accessory.

3. The mount adapter device of claim 1, wherein said resilient member is a coil spring.

4. The mount adapter device of claim 1, further comprising at least two said push rod members.

5. The mount adapter device according to claim 1, wherein said first base member further includes a first lateral surface having a first aperture therein for slidably receiving said push rod member.

6. The mount adapter device according to claim 1, wherein said second base member further includes a second lateral surface having a second aperture therein for receiving and retaining an end of said push rod member.

7. The mount adapter device according to claim 1, wherein said device is attached to the rail by depressing said push rod member in a direction which is transverse to the longitudinal axis of the rail, positioning the device on the rail, and releasing said push rod member.

8. The mount adapter device according to claim 7, wherein said device is detached from the rail by depressing said push rod member in a direction which is transverse to the longitudinal axis of the rail and removing the device from the rail.

9. The mount adapter device according to claim 1, wherein said base further includes a lower mounting surface configured to engage said upper mounting surfaces of the mounting projections.

10. The mount adapter device according to claim 9, wherein said device is configured to maintain at least three points of contact with said plurality of mounting projections of the rail upon attachment of the device to the rail.

11. The mount adapter device according to claim 10, wherein at least three points of contact are maintained among said first clamping member with said first inclined distal surfaces of the plurality of mounting projections, said second clamping member with said second inclined distal surfaces of the plurality of mounting projections, and said lower mounting surface of the base with said upper mounting surfaces of the plurality of mounting projections.

12. The mount adapter device according to claim 10, wherein said first clamping member does not bear against said first inclined proximal surfaces of the plurality of mounting projections, and said second clamping member does not bear against said second inclined proximal surfaces of the plurality of mounting projections.

13. The mount adapter device according to claim 9, further comprising at least one projection disposed on said lower mounting surface, wherein said at least one projection engages an elected transverse groove of the rail upon attachment of the device to the rail.

14. The mount adapter device according to claim 13, wherein a portion of the push rod member protrudes from the bottom mounting surface thereby acting as one of said at least one projections.

15. The mount adapter device according to claim 1, wherein said push rod member includes a knob and a shaft, said knob being attached to a first end of said shaft.

16. The mount adapter device according to claim 15, wherein said resilient member is interposed between the knob of the push rod member and the first base member.

17. The mount adapter device according to claim 15, wherein a first end of said shaft has external helical threads which engage complimentary internal threads inside a central aperture in said knob for selectively advancing the knob along the shaft when the knob is rotated down the shaft in a direction toward the first base member and for selectively retracting the knob along the shaft when the knob is rotated up the shaft in a direction away from the first base member.

18. The mount adapter device according to claim 15, wherein said device is attached to said rail in a second locked position by depressing said push rod member in a direction which is transverse to the longitudinal axis of the rail, positioning the device on the rail, releasing said push rod member, and rotating said knob down the shaft of the push rod member in a direction toward the first base member until the knob is adjacent to the first base member and the push rod member can no longer be depressed.

19. The mount adapter device according to claim 15, further comprising a sealing member disposed around a lower portion of said knob so as to be interposed between the knob and the first base member when the mount adapter device is in a second locked position wherein the knob is adjacent to the first base member.
