Abstract

Claims (29)

1. An accessory attachment system comprising:

a mounting rail comprising a plurality of protrusions and recesses, wherein the protrusions and recesses alternate in a repeating pattern along the mounting rail;

an accessory configured to be mounted on the mounting rail;

a friction plate configured to hold the accessory in a position on the mounting rail, wherein the friction plate comprises a friction feature configured to interact with the plurality of protrusions and recesses to create a friction force that holds the accessory in the position, wherein the friction feature is configured to cause a deflection of the friction plate in a deflection direction when interacting with the plurality of protrusions and recesses, wherein the friction plate and the friction feature are formed from the same piece in a unitary construction, wherein the friction plate is configured to temporarily deform, wherein the friction force is created by the interaction of friction features with the plurality of protrusions and recesses of the mounting rail; and

wherein the accessory attachment system allows for movement of the accessory along the rail with an application of force, wherein the applied force is greater than the friction force.

2. The accessory attachment system of claim 1 , wherein the accessory is shaped to receive a portion of the mounting rail.

3. The accessory attachment system of claim 1 , wherein movement of the accessory along the rail comprises movement substantially only along an axis parallel to a length of the rail.

4. The accessory attachment system of claim 1 , wherein the temporary deformation is in a direction perpendicular to a length of the rail.

5. The accessory attachment system of claim 1 , wherein the friction feature is “V-shaped” or “U-shaped”.

6. The accessory attachment system of claim 1 , wherein the friction feature extends partly into a protrusion of the mounting rail.

7. The accessory attachment system of claim 1 , and further comprising a second friction feature.

8. The accessory attachment system of claim 1 , wherein the friction plate is made of spring steel.

9. The accessory attachment system of claim 1 , wherein the friction plate is a uniform thickness throughout.

10. The accessory attachment system of claim 1 , wherein the friction plate is bent and contoured to form the friction feature.

11. The accessory attachment system of claim 1 , wherein the wherein the friction plate is attached to the accessory at more than 2 corners of the friction plate.

12. A method for attaching an accessory to a rail system, the method comprising:

providing an accessory attachment system, comprising:

a mounting rail comprising a plurality of protrusions and recesses, wherein the protrusions and recesses alternate in a repeating pattern along the mounting rail;

a friction plate configured to hold the accessory in a position on the mounting rail, wherein the friction plate comprises a friction feature configured to interact with the plurality of protrusions and recesses to create a friction force that holds the accessory in the position, wherein the friction feature is configured to cause a deflection of the friction plate in a deflection direction when interacting with the plurality of protrusions and recesses, wherein the friction plate and the friction feature are formed from the same piece in a unitary construction, wherein the friction plate is configured to temporarily deform, wherein the friction force is created by the interaction of friction features with the plurality of protrusions and recesses of the mounting rail; and

wherein the accessory attachment system allows for movement of the accessory along the rail system with an application of force, wherein the applied force is greater than the friction force;

coupling the friction plate to the accessory;

aligning the accessory on the rail system, wherein aligning comprises causing the accessory to receive a portion of the rail system such that the accessory is limited to movement along an axis parallel to a length of the rail, and wherein aligning the accessory on the rail system comprises a friction feature of the friction plate engaging a first rail feature of the rail system, generating a first friction force, wherein the friction feature causes a deflection of the friction plate in a deflection direction when the friction feature engages the first rail feature of the rail system;

applying a force to the friction plate, wherein the applied force is greater than the first friction force, and wherein applying a force allows the accessory to move along the rail system; and

positioning the accessory in a position on the rail system, wherein positioning the accessory comprises releasing the applied force, and wherein releasing the applied force causes the friction feature to engage a second rail feature of the rail system, generating a second friction force.

13. The method of claim 12 , wherein the second friction force is substantially the same as the first friction force.

14. The method of claim 12 , wherein coupling the friction plate to the accessory comprises coupling the friction plate to a module coupled to the accessory, wherein the module is adapted to receive the friction plate and wherein aligning comprises the module receiving the portion of the rail system.

15. The method of claim 12 , wherein coupling the friction plate to the accessory comprises a mechanical coupling.

16. The method of claim 12 , wherein the method is accomplished toollessly.

17. The method of claim 12 , wherein the applied force can be applied by a single user operating one-handed.
