Abstract

A loadable cord lock comprising an outer telescoping member and an inner telescoping member slidable within the outer telescoping member, each telescoping member having an aperture extending therethrough. The inner and outer members are biased against each other so that the apertures are not aligned, to pinch a cord threaded through the apertures. There is at least one leg having an L-shaped free end attached to the inner telescoping member and extending into the interior cavity of the outer telescoping member. There is at least one leg retainer located within the outer telescoping member to lock the inner telescoping member into first and second locking positions. In the first locking position, the apertures on the inner and outer telescoping members are aligned for feeding a cord therethrough, and in the second locking position, the apertures are not aligned to pinch the cord.

Claims

1. A loadable cord lock comprising:

an outer telescoping member having at least two side walls defining an interior cavity, and an aperture extending through said two side walls;

an inner telescoping member slidable within the cavity of said outer telescoping member and having an aperture extending therethrough;

means for biasing said inner and outer members so that said apertures are not aligned, to pinch a cord threaded through said apertures;

at least one leg attached to the inner telescoping member and extending into the interior cavity of the outer telescoping member, said leg having an L-shaped free end; and

a longitudinally-extending ramp connected at an upper end to the outer telescoping member and disposed within the cavity of the outer telescoping member, said ramp having a front side and a rear side and being angled toward the front side so as to bias the leg when said inner telescoping member is pressed into said outer telescoping member and said leg slides along the ramp, said ramp further comprising;

a first ledge forming a first locking position disposed at an intermediate point along the front side of the ramp for receiving the L-shaped portion of the leg when said inner telescoping member is pressed into said outer telescoping member;

a flexible lower foot portion extending below the slot; and

a second ledge positioned on the rear side of the ramp above the slot, wherein further pressing on the inner telescoping member causes the leg to slide out of the first ledge and around the lower foot portion and catch on the second ledge in a second locking position;

such that in the first locking position, the apertures on the inner and outer telescoping members are aligned for feeding a cord therethrough, and in the second locking position, the apertures are not aligned to pinch the cord.

2. The cord lock according to claim 1, wherein the L-shaped free end of the leg extends toward an inner portion of the cord lock.

3. The cord lock according to claim 1, wherein the leg is not biased when it resides in the slot or under the ledge.

4. The cord lock according to claim 1, wherein the biasing means comprises a spring coupled between the inner and outer telescoping members, said spring being compressed when said inner telescoping member is positioned into the first locking position.

5. The cord lock according to claim 1, further comprising means for preventing the inner telescoping member from returning to the first locking position once the second locking position has been attained.

6. The cord lock according to claim 1, wherein the inner telescoping member has a top surface that extends beyond the circumference of the outer telescoping member.

7. The cord lock according to claim 1, further comprising at least one shoulder element disposed at a lower section of a side wall of the outer telescoping member, said shoulder element having a sloped surface directed toward the rear side of the ramp, said shoulder element contacting the L-shaped free end of the leg as it slides down the ramp, and pushing said foot toward the rear side of the ramp while bending the lower foot portion of the ramp.

8. A loadable cord lock comprising:

an outer telescoping member having at least two side walls defining an interior cavity, and an aperture extending through said two side walls;

an inner telescoping member slidable within the cavity of said outer telescoping member and having an aperture extending therethrough;

means for biasing said inner and outer members so that said apertures are not aligned, to pinch a cord threaded through said apertures;

at least one leg attached to the inner telescoping member and extending into the interior cavity of the outer telescoping member, said leg having an L-shaped free end; and

a longitudinally-extending ramp located within the cavity of the outer telescoping member and connected to a side wall of the outer telescoping member, said ramp having a front side and a rear side and being angled toward the front side so as to bias the leg when said inner telescoping member is pressed into said outer telescoping member and said leg slides along the ramp, said ramp further comprising;

an indentation forming a first locking position disposed at an intermediate point along the front side of the ramp for receiving the L-shaped portion of the leg when said inner telescoping member is pressed into said outer telescoping member;

a flexible lower foot portion extending below the slot; and

an upwardly-extending slot positioned near the rear side of the ramp above the indentation, wherein further pressing on the inner telescoping member causes the leg to slide out of the indentation and around the lower foot portion and into the slot to form a second locking position;

such that in the first locking position, the apertures on the inner and outer telescoping members are aligned for feeding a cord therethrough, and in the second locking position, the apertures are not aligned to pinch the cord.

9. The cord lock according to claim 8, wherein the L-shaped free end of the leg extends toward an inner portion of the cord lock.

10. The cord lock according to claim 8, wherein the leg is biased when it resides in the indentation.

11. The cord lock according to claim 8, further comprising at least one shoulder element disposed at a lower section of a side wall of the outer telescoping member, said shoulder element having a sloped surface directed toward the rear side of the ramp, said shoulder element contacting the L-shaped free end of the leg as it slides down the ramp, and pushing said foot toward the rear side of the ramp while bending the flexible lower foot portion of the ramp.

12. A loadable cord lock comprising:

an outer telescoping member having at least two side walls defining an interior cavity, and an aperture extending through said two side walls;

an inner telescoping member slidable within the cavity of said outer telescoping member and having an aperture extending therethrough;

means for biasing said inner and outer members so that said apertures are not aligned, to pinch a cord threaded through said apertures;

at least one leg attached to the inner telescoping member and extending into the interior cavity of the outer telescoping member, said leg having an L-shaped free end; and

a longitudinally-extending ramp disposed within the cavity of the outer telescoping member and connected at an upper end to the outer telescoping member, said ramp having a front side and a rear side and being angled toward the front side so as to bias the leg when said inner telescoping member is pressed into said outer telescoping member and said leg slides along the ramp, said ramp further comprising;

an indentation forming a first locking position disposed at an intermediate point along the front side of the ramp for receiving the L-shaped portion of the leg when said inner telescoping member is pressed into said outer telescoping member;

a flexible lower foot portion extending below the indentation; and

a ledge positioned on the rear side of the ramp above the indentation, wherein further pressing on the inner telescoping member causes the leg to slide out of the indentation and around the lower foot portion and up to the ledge to form a second locking position;

such that in the first locking position, the apertures on the inner and outer telescoping members are aligned for feeding a cord therethrough, and in the second locking position, the apertures are not aligned to pinch the cord.

13. The cord lock according to claim 12, wherein the L-shaped free end extends toward the exterior of the cord lock.
