Abstract

Locking systems and method of manufacturing the same are provided. A locking system for fall protection includes a braking lever. The braking includes a shock absorber. The shock absorber includes a plurality of coils. The shock absorber also includes a plurality of breakaway interfaces coupling the plurality of coils together. Each of the plurality of breakaway interfaces are configured to decouple two of the plurality of coils at a different force. At least one of the breakaway interfaces defines at least one deformable finger defined on one of the plurality of coils of the shock absorber interfacing with another coil of the shock absorber.

Claims (16)

1 . A method of manufacturing a locking system for fall protection, the method comprising providing a shock absorber on a braking lever, the method comprising:

creating a plurality of coils by bending a material, each coil of the plurality of coils including a bending portion of the material; and

coupling the plurality of coils together by coupling a plurality of breakaway interfaces, wherein each of the plurality of breakaway interfaces are configured to decouple two of the plurality of coils at a different force, wherein at least one of the breakaway interfaces defines at least one deformable finger defined on one of the plurality of coils of the shock absorber interfacing with another coil of the shock absorber.

2 . The method of claim 1 , further comprising providing a housing, wherein the housing defines a guide path through which the housing is slideably attached to a guide member.

3 . The method of claim 1 , wherein the method of manufacturing the braking lever further comprises a braking end that is configured to engage the guide member.

4 . The method of claim 1 , wherein at least one breakaway interface comprises a clipping mechanism configured to increase the force at which the shock absorber deforms.

5 . The method of claim 4 , wherein the clipping mechanism is configured to fit around at least one coil of the shock absorber, such that the clipping mechanism resists the opening force of the shock absorber.

6 . The method of claim 4 , wherein the at least one breakaway interface comprising the clipping mechanism further comprises a clip aperture configured to receive the clipping mechanism.

7 . The method of claim 4 , wherein the clipping mechanism is removable.

8 . The method of claim 1 , wherein the plurality of coils are made out of a single coiled material.

9 . The method of claim 1 , wherein at least one of the breakaway interface comprises two hooks defined on adjacent coils, such that each of the two hooks are configured to withstand a predetermined force at which the hook decouples.

10 . The method of claim 1 , wherein the shock absorber comprises at least:

a first breakaway interface defines at least one deformable finger defined on one of the plurality of coils of the shock absorber interfacing with another coil of the shock absorber;

a second breakaway interface defines two hooks on adjacent coils, such that each of the two hooks are configured to withstand a predetermined force at which the hook decouples; and

a third breakaway interface defines a clipping mechanism configured to increase the force at which the shock absorber deforms, wherein each of the first breakaway interface, the second breakaway interface, and the third breakaway interface are configured to decouple at a different force.

11 . The method of claim 1 , wherein the another coil of the shock absorber includes a finger receiving aperture to receive the least one deformable finger therein.
