MODULAR SYSTEM FOR MOUNTING FIREARM ACCESSORIES AND METHOD FOR ATTACHING FIREARM ACCESSORY TO FIREARM

1 . A modular system for mounting firearm accessories, comprising:

a first mounting member capable of receiving a firearm accessory;

a second mounting member capable of engaging with the first mounting member; and

a joining mechanism for releasably engaging the first and second mounting members to a mounting site,

wherein the joining mechanism is rotatable about an axis perpendicular to a longitudinal direction of a firearm.

2 . The system of claim 1 , wherein the joining mechanism comprises a column and a grip pivotably coupled to an end of the column.

3 . The system of claim 2 , further comprising a locking member on the second mounting member, the locking member being capable of engaging with the grip to maintain the grip at a stationary position.

4 . The system of claim 3 , wherein the locking mechanism comprises a hook such that, when the locking mechanism is engaged with the grip, the hook is engaged with a central portion of the grip.

5 . The system of claim 1 , further comprising:

an adjustment mechanism coupled to the joining mechanism for adjusting engagement tightness of the first and second mounting members with the mounting site.

6 . The system of claim 5 , wherein the adjustment mechanism comprises a sprocket wheel defining a plurality of teeth positions and a detent device coupled to one of the teeth positions.

7 . The system of claim 6 , wherein an angle between neighboring teeth positions ranges from about 10 degrees to about 30 degrees.

8 . The system of claim 6 , wherein the sprocket wheel is engaged with the joining mechanism.

9 . The system of claim 6 , wherein the detent device is movably disposed in the first mounting member.

10 . The system of claim 6 , wherein the detent device is retractable into the first mounting member to allow rotation of the sprocket wheel.

11 . A method for attaching a firearm accessory to a firearm, the method comprising:

A) providing a modular system for mounting firearm accessories, the system comprising:

a first mounting member capable of receiving a firearm accessory,

a second mounting member capable of combining with the first mounting member, and

a joining mechanism for releasably combining the first mounting member with the second mounting member;

B) attaching the first and second mounting members to a mounting site of a firearm; and

C) joining the first and second mounting members by rotating the joining mechanism about an axis perpendicular to a longitudinal direction of a firearm.

12 . The method of claim 11 , further comprising:

D) attaching a firearm accessory to the first mounting member of the modular system.

13 . The method of claim 18 , wherein C) comprises rotating the joining mechanism through an angle of approximately 180 degrees.

14 . The method of claim 11 wherein the modular system for mounting firearm accessories further comprises:

an adjustment mechanism movable coupled to the joining mechanism for adjusting engagement tightness of the first and second mounting members with the mounting site.

15 . The method of claim 14 further comprising:

D) adjusting engagement tightness of the first and second mounting members with the mounting site using the adjustment mechanism.

16 . The method of claim 15 , wherein the adjustment mechanism comprises a sprocket wheel defining a plurality of teeth about a perimeter thereof and wherein D) comprises:

D1) rotating the sprocket wheel of the adjustment mechanism to adjust the relative position of the first and second mounting members to a mounting site.

17 . The method of claim 16 , wherein the plurality of teeth of the sprocket wheel are disposed about the perimeter thereof at predetermined angle ranging from approximately 10 degrees to approximately 30 degrees wherein D1) comprises:

D1a) rotating the sprocket wheel comprises rotating the sprocket wheel incrementally for a predetermined angle in each step.

18 . The method of claim 16 , wherein the adjustment mechanism comprises a detent device engagable with one of the plurality of teeth of the sprocket wheel and wherein D) comprises:

D2) engaging the sprocket wheel with the detent device to fix the relative position of the first and second mounting members to each other and the mounting site.
