Abstract
This perdurable composite cylinder methodology allows for the inclusion of load cushioning or shock absorbing at the primary site of the generation of the disturbance. This is accomplished because the core to covering interference fit of the composite cylinder form a perdurable mechanical bond between the two parts and the bond is of a different resiliency at different sections of the resultant cylinder assembly. This feature can be used to provide cushioning capability in the rollers for applications where none was present heretofore. This feature may also function to augment or eliminate existing auxiliary shock absorbing mechanisms.
Description
- None.
- The federal involvement with this nonprovisional utility patent application is; null.
- Not Applicable.
- In prior art, any cushioning which was provided in the rolling elements of roller skates was, or is either ineffectual or devoid of this feature.
- A flexible tube of polyurethane or equivalent material has its' internal diameter forced over a perdurable rigid nylon core or equivalent material, that present a complex series of rigid longitudinal convex and concave diameters, to the flexible tube. This series of rigid core obstruction over which the flexible tube must be forced, present their greatest test initially and there after, their innate intensity is diminished in steps. Until the leading edge of the flexible tube encounters an impassable core wall. At which point the longitudinal advance of the flexible tube over the rigid core is halted. The completed composite cylinder can now providing supplemental cushioning to an existing shock absorbing system or eliminate the need for such an auxiliary mechanisms.
- FIG. 1 is an end view of the of the composite cylinder with section arrows only through the core covering. FIG. 2 is a plan view of the composite cylinder with only the core covering shown in section.
- The nylon or equivalent core of the composite roller skating cylinder can be molded from appropriate resin or machined from rod stock. While the covering, for best results, should be sliced from polyurethane or equivalent tubing stock. The appropriate longitudinal flexible polyurethane tubing section is then forced to fit longitudinally over the series of complex peaks and valleys of the rigid nylon core's outer diameter.
- This interference fit forms a perdurable mechanical bond between the rigid core and the flexible tube section. With the unique capability of providing a wide range of firmness characteristics at a given tubing section.
- This composite cylinder when fitted with application appropriate bearing, shaft and chassis will cushion a transported weight.
Claims (6)
1. A perdurable composite roller skating cylinder with a rigid nylon or equivalent core (A), with provisions for the mounting of anti-friction ball bearings (H).
2. A perdurable composite roller skating cylinder with a dual function initial obstruction (F), for the flexible polyurethane or equivalent tubing (B), that provides initial guidance for the flexible outer shell (B), and also serves as a back stop when the flexible outer shell has reached its' final longitudinal core position (G).
3. A perdurable composite roller skating cylinder with a permanent rigid core barricade (G), at the termination point of the outer flexible shell (B).
4. A perdurable composite roller skating cylinder with a series of rigid core diametral concave grooves (C), (E), to accommodate the natural stress relieving of the material of the flexible polyurethane or equivalent tube (B).
5. A perdurable composite roller skating cylinder with rigid core diametral convex peaks (J), (D), that provide a mechanical interference fit of progressively diminishing intensity for the flexible outer shell (B).
6. A perdurable composite roller skating cylinder with a nylon or equivalent core (A), that has a flexible outer shell of polyurethane or equivalent tubing (B), that is inextricability bound by interference fit on three levels, that of complex diametral mechanical interference of diminishing longitudinal intensity, with positive physical obstacles at the longitudinal termination points (L), of the flexible outer shell (F), (G), and diametral concave core grooves (C), (E), for the natural stress relieving of the material of the outer shell (B).
