Strap attachment device
View Patent ↗A strap attachment device includes a main body with a lower body end that has an opening suited for a strap. Based on its position, a cam lever at the opening of the lower body end holds or releases the strap, permitting adjustment of the length of the strap that enters the opening. Extending upward from the lower body end is an upper body end that is curved into a hook or any other shape appropriate for connection to an object. A flexible or translatable gate may extend from the main body so as to prevent the upper body end from inadvertently becoming detached from the object. Slip-resistance on the upper body end resists slippage between the upper body end and the object during side-to-side movements. Ends of the strap may include a loop or handle or connect to other devices.
1. A cam hook device, including:
a) a main body, including:
1) a lower body end, including:
(i) a rectangular opening between opposing sides, wherein each of the opposing sides includes a lower hole and an upper hole; and
(ii) a base including a face, wherein the base is situated below the rectangular opening;
2) an upper body end extending from the lower body end, the upper body end including a curved hook portion having a concave side and an opposing convex side;
b) a cam lever situated at the rectangular opening of the lower body end, the cam lever including:
1) an irregular lower face;
2) a handle opposite the lower face; and
3) a cylindrical bearing situated between the lower face and the handle, wherein the cylindrical bearing is interrupted by a bearing gap situated between opposing ends of the cylindrical bearing;
4) wherein:
(i) a first pin is received within the cylindrical bearing and through the lower holes of the opposing sides of the rectangular opening, and
(ii) the cam lever is rotatable on the first pin, such that the handle of the cam lever covers the rectangular opening of the lower body end to varying degrees as the cam lever rotates;
c) a torsion spring spring-loading the cam lever, the spring including a central hole, wherein:
1) the spring is situated in the bearing gap, and
2) the first pin is inserted through the central hole of the spring;
d) a gate extending from the lower body end toward the upper body end, the gate including a fixed end having two opposing lower holes and two opposing upper holes, wherein:
1) the first pin is inserted through the two opposing lower holes, and
2) a second pin is inserted through the two opposing upper holes and the two upper holes of the opposing sides of the lower body end; and
e) a strap inserted through the rectangular opening of the lower body end, wherein:
1) the strap is held in place by being pressed between the toothed face of the cam lever and the irregular face of the base of the lower body end, and
2) the strap is released from the base of the main body by rotating the cam lever on the lateral axis.
2. The cam hook device of claim 1 , wherein the strap further includes:
a) a first end having a loop or a handle; and
b) a second end, wherein the second end attaches to a fitness product selected from a group including a handle, a cuff, and an elastic cable.
