Abstract

The present invention is a slip grip device, which permits a cord to be adjusted to any given position or length. It adjusts through a tension mechanism, while allowing the cord to break apart at a pre-determined pressure, thus ensuring safety in the event that the cord is inadvertently caught. An interference fit within keyways and keyway cavities of the mechanism allowing for anchoring a cord and adjusting its length. This mechanism serves as an anchor for the end of various types of cord, while enabling the cord to slip with a set resistance, while providing enough grip to hold at any desired length or location. The cord length can be readjusted and reset countless times. The device consists of two parts designed to fit together around the cord. The invention contains no moving parts and there is no glue, springs staples, wire, wax, nor heat used in assembly.

Claims

1. A slip grip cord adjustment device, comprising:

a first body;

a second body;

a tapered interior defined by at least one of the first body or the second body, the tapered interior being adapted to receive both an anchored cord and a sliding cord in side by side relation with full length interior contact, the sliding cord sliding during usage to permit cord adjustment;

means for anchoring one end of the anchored cord to one of the first body or the second body;

a first compression member on the first body;

a second compression member on second body, the first compression member and the second compression member being adapted to cooperatively exert a compressive force solely upon the anchored cord;

first engagement means on the first body; and

second engagement means on the second body, the second engagement means being adapted to engage the first engagement means to hold the first body and the second body together and cause the first compression member and the second compression member to exert a compressive force upon the anchored cord positioned in the tapered interior, thereby causing the anchored cord to spread outwardly and exert an interference force along a portion of a length of the sliding cord in full length interior contact with the anchored cord to resist sliding movement of the sliding cord until a predetermined force threshold is reached.

2. The slip grip cord adjustment device as defined in claim 1, wherein the first engagement means is one of a male member or a female receptacle and the second engagement means is the other of the male member or the female receptacle.

3. The slip grip cord adjustment device as defined in claim 1, wherein the engagement means is a friction fit locking engagement and at the predetermined force threshold, the engagement means holding the first body and the second body together separate, thereby releasing the anchored cord.

4. The slip grip cord adjustment device as defined in claim 1, wherein the means for anchoring one end of the anchored cord is an upstanding cord engaging member and at the predetermined pressure threshold, the upstanding cord engaging member bends and releases the anchored cord.

5. The slip grip cord adjustment device as defined in claim 4, wherein the cord engaging member is secured to one of the first body or the second body and a pressure member is provided on the other of the first body and the second body to maintain the anchored cord in engagement with the cord engaging member.

6. The slip grip cord adjustment device as defined in claim 1, wherein the means for anchoring one end of the anchored cord includes a first prong on the first body and a second prong on the second body, the anchored cord being clamped between the first prong and the second prong when the first engagement means and the second engagement means are engaged.

7. The slip grip cord adjustment device as defined in claim 1, wherein an end stop impinges into the tapered interior to enclose the one end of the anchored cord and create a narrowing which increases friction upon the sliding cord.

8. The slip grip cord adjustment device as defined in claim 1, wherein the tapered interior has radiused end portions, thereby reducing chafing of the sliding cord.

9. The slip grip cord adjustment device as defined in claim 1, wherein a sliding cavity is provided in the tapered interior to accommodate sliding cord, the sliding cavity being formed from a first recessed cavity on first body and a second recessed cavity on second body.

10. The slip grip cord adjustment device as defined in claim 9, wherein the sliding cavity is of substantially the same cross-sectional dimension as the sliding cord.

11. The slip grip cord adjustment device as defined in claim 1, wherein the tapered interior is tapered in two dimensions.

12. A slip grip cord adjustment device, comprising:

a first body;

a second body;

a tapered interior defined by at least one of the first body or the second body, the tapered interior tapered in two dimensions and being adapted to receive both an anchored cord and a sliding cord in side by side relation with full length interior contact, the sliding cord sliding during usage to permit cord adjustment;

means for anchoring one end of the anchored cord including a pressure member on the first body and an upstanding cord engaging member secured to the second body;

a first compression member on the first body;

a second compression member on second body, the first compression member and the second compression member being adapted to cooperatively exert a compressive force solely upon the anchored cord;

a sliding cavity is provided in the tapered interior to accommodate sliding cord, the sliding cavity is of substantially the same cross-sectional dimension as the sliding cord and is formed from a first recessed cavity on first body and a second recessed cavity on second body;

first engagement means on the first body; and

second engagement means on the second body, the second engagement means being adapted to engage the first engagement means to hold the first body and the second body together, cause the pressure member to force the anchored cord into engagement with the cord engaging member, and cause the first compression member and the second compression member to exert a compressive force upon the anchored cord positioned in the tapered interior, thereby causing the anchored cord to spread outwardly and exert an interference force along a portion of a length of the sliding cord in full length interior contact with the anchored cord to resist sliding movement of the sliding cord until a predetermined force threshold is reached.

13. The slip grip cord adjustment device as defined in claim 12, wherein the first engagement means are male members on the first body and the second engagement means are female receptacles on the second body.

14. The slip grip cord adjustment device as defined in claim 13, wherein the male members and the female receptacles are engaged in a friction fit locking engagement.
