Abstract

A connecting device for a weapon accessory has a seat having a sliding rack that removably connects the longitudinal groove of a weapon, and one or more gripping blocks disposed adjacent corresponding side walls of the seat. The gripping block assumes a first position where the gripping block extends inwardly towards the sliding rack to engage a selected transverse groove of the weapon, and a second position where the gripping block extends outwardly away from the respective side wall of the seat to release the longitudinal groove of the weapon. The connecting device also includes a control mechanism operatively coupled to the gripping block. The control mechanism assumes a normal position with the control mechanism controlling the gripping block to maintain the gripping block in the first position, and actuation of the control mechanism causes the gripping block to assume the second position.

Claims

1. A connecting device for a weapon accessory, comprising:

a seat having a sliding rack that removably connects a sliding groove of a weapon, the seat having two opposite side walls;

two gripping blocks disposed adjacent opposing side walls of the seat, each gripping block assuming a first position where the gripping block extends inwardly towards the sliding rack, and a second position where the gripping block extends outwardly away from the respective side wall of the seat;

a control mechanism operatively coupled to each gripping block;

wherein the control mechanism assumes a normal position with the control mechanism controlling each gripping block to maintain the gripping block in the first position; and

wherein actuation of the control mechanism causes each gripping block to assume the second position.

2. The device of claim 1, wherein each gripping block has an angled top surface that communicates with an angled side surface, with the inclination of the angled surfaces extending from an outer side of the gripping block to an inner side thereof.

3. The device of claim 1, wherein the sliding rack of the seat has a front angled surface.

4. The device of claim 1, wherein the control mechanism includes a button and a first elastic component disposed between the gripping blocks.

5. The device of claim 4, further including a second elastic component disposed between the button and the seat, and normally biasing the button away from the gripping blocks.

6. The device of claim 4, further including a second elastic component disposed between the button and the seat, and normally biasing the button towards the gripping blocks.

7. The device of claim 4, wherein the button has a rear end having two outwardly-extending angled surfaces, and wherein each gripping block has an inwardly-extending angled surface that engages one of the two outwardly-extending angled surfaces, such that actuation of the button pushes the gripping blocks away from each other.

8. The device of claim 4, wherein the button has a rear end having two inwardly-extending angled surfaces, and wherein each gripping block has an outwardly-extending angled surface that engages one of the two inwardly-extending angled surfaces, such that actuation of the button causes the outwardly-extending angled surfaces to disengage the inwardly-extending angled surfaces.

9. The device of claim 1, wherein the control mechanism comprises:

two crossing bars that are pivoted with respect to each other about a pivot point, each bar having a first end that carries one of the gripping blocks, and a second end; and

elastic components that are provided between each second end of the bars and the seat.

10. The device of claim 1, wherein the control mechanism comprises:

two adjacent bars that are pivoted with respect to each other about a pivot point, each bar having a first end that carries one of the gripping blocks, and a second end; and

elastic components that are provided between each second end of the bars and the seat.

11. The device of claim 1, wherein the control mechanism comprises:

two adjacent rods that move in opposite directions, each rod having a first end that carries one of the gripping blocks, and a second end; and

an elastic component that couples the two rods adjacent the first end to normally bias the gripping blocks towards each other.

12. The device of claim 1, wherein the control mechanism comprises:

a threaded screw having opposing first and second ends; and

wherein each gripping block is threadably engaged to one of the first or second ends of the screw, and threadably manipulated along the screw to adjust the distance between the two gripping blocks.

13. A weapon assembly, comprising:

(a) a weapon having longitudinal groove and a plurality of transverse grooves provided along the longitudinal groove;

(b) a connecting device, comprising;

a seat having a sliding rack that removably connects the longitudinal groove of the weapon, the seat having two opposite side walls;

two gripping blocks disposed adjacent opposing side walls of the seat, each gripping block assuming a first position where the gripping block extends inwardly towards the sliding rack to engage a selected transverse groove of the weapon, and a second position where the gripping block extends outwardly away from the respective side wall of the seat to release the longitudinal groove of the weapon;

a control mechanism operatively coupled to each gripping block;

wherein the control mechanism assumes a normal position with the control mechanism controlling each gripping block to maintain each gripping block in the first position; and

wherein actuation of the control mechanism causes each gripping block to assume the second position.

14. The assembly of claim 13, wherein the control mechanism includes a button and a first elastic component disposed between the gripping blocks.

15. The assembly of claim 14, further including a second elastic component disposed between the button and the seat, and normally biasing the button away from the gripping block.

16. The assembly of claim 14, further including a second elastic component disposed between the button and the seat, and normally biasing the button towards the gripping blocks.

17. The assembly of claim 14, wherein the button has a rear end having two outwardly-extending angled surfaces, and wherein each gripping block has an inwardly-extending angled surface that engages one of the two outwardly-extending angled surfaces, such that actuation of the button pushes the gripping blocks away from each other.

18. The assembly of claim 14, wherein the button has a rear end having two inwardly-extending angled surfaces, and wherein each gripping block has an outwardly-extending angled surface that engages one of the two inwardly-extending angled surfaces, such that actuation of the button causes the outwardly extending angled surfaces to disengage the inwardly-extending angled surfaces.

19. The device of claim 13, wherein the control mechanism comprises:

a threaded screw having opposing first and second ends; and

wherein each gripping block is threadably engaged to one of the first or second ends of the screw, and threadably manipulated along the screw to adjust the distance between the two gripping blocks.
