Slip grip device
First Claim
1. A slip grip cord adjustment device, comprising:
- a first body;
a second body;
a tapered channel in at least one of the first body or the second body, the tapered channel being adapted to receive an anchored cord and a sliding cord;
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 upon the anchored cord;
first engagement means on the first body;
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 channel, thereby causing the anchored cord to spread outwardly and exert an interference force upon the sliding cord to resist sliding movement of the sliding cord until a predetermined force threshold is reached.

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.

15. A slip grip cord adjustment device, comprising:
-
a first body;
a second body;
a tapered channel in at least one of the first body or the second body, the tapered channel tapered in two dimensions and being adapted to receive an anchored cord and a sliding cord;
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 upon the anchored cord;
a sliding cavity is provided in the tapered channel 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;
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 channel, thereby causing the anchored cord to spread outwardly and exert an interference force upon the sliding cord to resist sliding movement of the sliding cord until a predetermined force threshold is reached. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22)

23. A slip grip cord adjustment device, comprising:
-
a first body;
a second body;
a tapered channel formed when the first body and the second body are connected, the tapered channel tapered in two dimensions and is adapted to receive an anchored cord and a sliding cord, the tapered channel having radiused end portions, thereby reducing chafing of the sliding cord;
means for anchoring one end of the anchored cord including a pressure member on the first body, an upstanding cord engaging member secured to the second body, a first clamping member on the first body and a second clamping member on the second body;
an end stop impinges into the tapered channel to enclose the one end of the anchored cord;
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 upon the anchored cord;
a sliding cavity is provided in the tapered channel 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 the second body;
first engagement means in the form of male members on the first body;
second engagement means in the form of female receptacles on the second body, the second engagement means being adapted to engage the first engagement means in a friction fit locking engagement to hold the first body and the second body together, cause the anchored cord to be clamped between the first clamping member and the second clamping member, 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 channel, thereby causing the anchored cord to spread outwardly and exert an interference force upon the sliding cord to resist sliding movement of the sliding cord along the sliding cavity until a predetermined force threshold is reached at which time either the upstanding cord engaging member bends or the first engagement means and the second engagement means holding the first body and the second body together separate, thereby releasing the anchored cord.
