Abstract

A spring comprising a spring itself and end seat plates and a mount. In the spring seat plates are mechanically connected (constantly, variably, or actuable to connect) to each other and to the mount, so when a force or moment is applied to one of those seat plates its movement induce the movement of other seat plate as well, changing the total movement of the spring. Furthermore, there are provided mechanical means (a cams, a gears, a levers etc.) for changing the linkage between the end seat plates and the mount, which result in increasing, remaining the same (constant spring) or decreasing the spring constant. So, the spring constant of the spring can be controlled as to be adjustable.

Claims2

Dependent claims

A spring comprising:

(a) a first end seat plates;
(b) a second end east plate with a hole in the center;
(b) a spring mount (load supporting member);
(c) a spring coil, located between said first and said second end seat plates;
(d) a gear rack fixed to said first seat plate and going through the hole in said second seat plate;
(e) a cams with cogs, gears, or gears with arms, located between said second seat plate and said spring mount and pivotally connected to said spring mount and engaged to the cogs of said gear rack
so when a force or moment is applied to one of said seat plates its movement induces the movement of said second seat plate as well, changing the total deflection of said spring coil, so by controlling the linkage between said first and second seat plates and said spring coil the spring constant can be controlled as to be adjustable.
