Abstract

A cord lock has a housing with an interior cavity and an opening extending between the front and the back for receiving a cord, and an actuator having two legs that are configured to slide within the interior cavity of the housing. A spring is disposed between the housing and the actuator to bias the actuator in a raised position relative to the housing. There is a cam disposed in the interior cavity of the housing. The bottom of the cam is rotatably connected to the housing and the top is rotatably connected to the legs of the actuator. In a resting position, the spring presses the top of the cam against the housing such that when a cord is extended through the opening, the cam locks the cord in place between the cam and the housing. Depressing the actuator compresses the spring and rotates the cam.

First claim

What is claimed is:

1 . A cord lock comprising:
a housing having two side walls, a top surface, a bottom surface, a front, a back, an interior cavity and an opening extending between the front and the back for receiving a cord, a cam disposed in the interior cavity, the cam having a channel therethrough, an actuating hook and a gripping portion; a post extending through the channel in the cam and being rotatably connected to the side walls of the housing; a spring connected to the post and being configured for biasing the cam in a locked position, such that a cord extending through the opening is pressed against the housing by the gripping portion of the cam; and an actuator having a cross-bar configured for arrangement in the actuating hook, and a handle arranged opposite the cross-bar, such that pressing the lever moves the cam out of the locked position to release the cord from the housing.

2 . The cord lock according to claim 1 , further comprising protrusions extending from the side walls of the housing, wherein the side walls of the actuator rests on the protrusions when the cross bar is arranged in the actuating hook, such that protrusions form a pivot point for the handle.

3 . The cord lock according to claim 1 , wherein the spring is a torsion spring that extends around the post.

4 . The cord lock according to claim 3 , wherein the channel has a slot that is configured for accommodating an end of the torsion spring.

5 . The cord lock according to claim 1 , wherein the gripping portion contains a plurality of teeth.

6 . The cord lock according to claim 1 , wherein the post extends through apertures in the side walls of the housing.
