Abstract
By way of example, a cam assembly and strap based closure system using a spiral is configured for bringing two sides of an article together. When the user inserts the strap into the cam assembly and turns a knob, the strap is driven into the cam assembly and the strap pins engage one or more cam spirals. The system is configured such that strap pins are engaged at a constant angle which may be self-locking. The system is infinitely adjustable and the torque felt by the knob is constant. The system is configured to be a quick release system and allows rapid insertion of the strap for faster operation.

A reel and strap based system for bringing two sides of an article together, the system comprising:
- a housing adapted to receive a strap, the housing comprising a track insert provided in the housing, the track insert configured to receive the strap;
- said strap adapted to feed into the housing and track insert, the strap comprising strap pins configured to engage in a cam;
- said cam comprising at least one spiral, the cam configured to pull the strap pins, wherein the at least one spiral comprises a logarithmic spiral;
- and
- a knob configured to rotate said cam.
A method for drawing two objects towards each other, the method comprising:
- providing a housing adapted to receive a strap, the housing comprising a track insert provided in the housing, the track insert configured to receive the strap;
- adapting said strap to feed into the housing and track insert, the strap comprising strap pins configured to engage in a cam;
- configuring said cam to pull the strap pins, the cam comprising at least one spiral, wherein the at least one spiral comprises a logarithmic spiral;
- providing a knob configured to rotate the cam;
- positioning the housing, the cam, and the knob on a first object;
- positioning the strap on a second object;
- and
- rotating the knob to drive the strap into the housing to pull the first object and second object towards each other.
A method for drawing two objects away from each other, the method comprising:
- providing a housing adapted to receive a strap, the housing comprising a track insert provided in the housing, the track insert configured to receive the strap;
- adapting said strap to feed into the housing and track insert, the strap comprising strap pins configured to engage in a cam;
- configuring said cam to pull the strap pins, the cam comprising at least one spiral, wherein the at least one spiral comprises a logarithmic spiral;
- providing a knob configured to rotate the cam;
- positioning the housing, the cam, and the knob on a first object;
