Embodiment Construction

[0057] [0043] While specific embodiments of the invention will now be described with reference to the accompanying drawings, it is to be understood that these embodiments are exemplary only and are but a few of the many possible embodiments that may represent applications of the principles of the invention. Various changes and modifications apparent to those skilled in the art to which the invention pertains are deemed to be within the spirit, scope and contemplation of the invention as further defined in the appended claims.

[0058] [0044] Referring to FIG. 1, which is a partial front elevational view in cross section, there is illustrated a fork 100 incorporating an adjustable progressive coil spring system 50 of the present invention within a first fork leg 200. The first fork leg 200 is constructed by combining a set of two matched telescopic hollow rods (first inner telescopic hollow rod 202 and second outer telescopic hollow rod 204 ). Similarly, the second fork leg 201...

Abstract

An adjustable coil spring system placed within a leg of a vehicle such as a mountain bicycle fork. The spring system comprises an adjustable first soft spring seated on top of a second firm spring having greater length than the first soft spring. A coupler assembly is positioned between two springs comprised of a threaded bolt threadedly received within a coupler. A spring adjustment means may comprise a knob connected to the threaded bolt through a non-round shaped shaft, wherein the threaded bolt is disposed within the first soft spring. As the knob rotates, the coupler is moved up along the threaded bolt, decreasing the length of the first soft spring, thereby increasing firm spring characteristics of the spring system. As the knob rotates in an opposite direction, the coupler moves down, increasing the length of the first soft spring, thereby increasing soft spring characteristics of the spring system.

Description

technical field [0001] [0001] The present invention relates to the field of vehicle suspension systems, such as those used in bicycles and motorcycles, which are designed to improve the compressibility of the spring system in response to riding conditions and rider weight. Background technique [0002] [0002] Spring and damping systems for varying the spring characteristics of mountain bike forks according to riding conditions or rider weight are generally well known. In the prior art, one way of changing the spring characteristics is to change the whole spring assembly to a different spring assembly. Generally speaking, the rider wants the suspension spring to be soft during normal driving, but harder if the rider hits a bump so the rider gets a minimum amount of protection. In the prior art, another variant is to have a spring with both properties. Also, another variation is to have one spring inside the other, with the softer spring on the outside and the harder spring ...
