Abstract
A roller skate or skate board that has a steering and shock absorbing suspension for the wheels (57, 58), characterized by an axle and pivot unit (24, 38, 39) that is partially embedded in a shock absorber (2, 13, 23, 27) that extends longitudinally in the direction of the pivot axis, held in a bracket that is mounted to the roller skate or skateboard with the pivot at an acute angle to a sole plate of the roller skate or skateboard.
Description
- This invention lies in the field of roller skates and skateboards.
- Several designs have been attempted that allow skates to both run on a curved path under control of the skater and to improve the “feel” of the skate by absorbing shocks from the skating surface. Examples of these are described in U.S. Pat. No. 2,086,557, U.S. Pat. No. 3,087,739 and the present inventor's published
patent application GB 2 416 313 A. Similarly designs have been made for skate boards, for example described in U.S. Pat. No. 4,194,752 and U.S. Pat. No. 6,474,666. These designs have generally been based on support of the wheel axles by resilient means which is constrained to allow movement of the axles upon compression of the resilient means in a direction inclined from the vertical which introduces a component of horizontal movement and hence a steering effect of the axles. - A roller skate or skate board in accordance with this invention is characterized by the assembly of a unit including a rigidly joined axle and pivot, a shock absorber extending co-axially with the pivot and substantially wholly embedding the pivot and a bracket, the bracket mounting the shock absorber and axle and pivot unit on a sole plate of the skate or skateboard with the pivot at an acute angle to the sole plate.
- Further in accordance with the invention there is provided an assembly adapted for mounting on a roller skate or skateboard consisting of a unit comprising a rigidly joined axle and pivot, a shock absorber extending co-axially with the pivot and substantially wholly embedding the pivot and a bracket.
- Generally there will be two such assemblies in a skate or skateboard, one for a front axle and the other for a rear axle, which will provide a steering effect on both axles, however, the invention may be implemented with only one such assembly.
- The assembly may conveniently be mounted on a sole plate for the skate but alternatively the bracket may be mounted directly to a sole of a boot of the roller skate or a sole plate may be incorporated in the boot.
- In accordance with one embodiment of the invention a pair of side plates are added to the assembly, designed to hold the shock absorber with embedded axle and pivot unit in the bracket. The side plates may have flanges to enhance their holding action.
- In accordance with a preferred embodiment of the invention dual side plates are provided that span between two assemblies, each assembly being of a unit comprising a rigidly joined axle and pivot, a shock absorber extending co-axially with the pivot and substantially wholly embedding the pivot and a bracket, each bracket mounting the shock absorber and axle and pivot unit.
- In accordance with another embodiment of the invention the bracket may have a split that allows the bracket to be partially opened to facilitate insertion of the shock absorber with embedded axle and pivot unit with a bolt to then close the split.
- In accordance with another embodiment of the invention the bracket mounts an upper region of the shock absorber with embedded axle and pivot unit with a lower bracket mounting a lower region of the shock absorber with embedded axle and pivot unit, the bracket and lower bracket fixed to the sole plate of the skate or skateboard.
- In accordance with another embodiment of the invention a dual lower bracket is provided that spans between two assemblies, each assembly being of a unit comprising a rigidly joined axle and pivot, a shock absorber extending co-axially with the pivot and substantially wholly embedding the pivot and a bracket, each bracket mounting the shock absorber and axle and pivot unit on a sole plate of the skate or skateboard with the pivot at an acute angle to the sole plate and the dual lower bracket mounting the lower regions of the shock absorber and axle and pivot unit.
- In accordance with a still further embodiment of the invention two brackets are integrally formed as one component forming also the sole plate, each bracket mounting a shock absorber and axle and pivot unit with the pivot at an acute angle to the sole plate.
- The assembly may incorporate a brake pad or provision for attachment of a brake pad.
- In accordance with a preferred embodiment of the invention the unit including an axle and pivot also incorporates a flange oriented orthogonally to an axis of the pivot.
- The pivot may be formed as a solid rod, a tube or a folded sheet metal.

FIG. 1 shows an assembly of a unit “A” including a rigidly joinedaxle 6 andpivot 5, ashock absorber 2 extending co-axially with the pivot and substantially wholly embedding the pivot, a bracket 1 and the unit including theaxle 6 andpivot 5 also incorporates aflange 4 oriented orthogonally to the axis of the pivot. -
FIG. 2 shows the separated parts of the assembly, the axle and pivot are made of a high strength metal such as a suitable grade of steel, the shock absorber is a resilient material such as a natural or synthetic rubber such as a butadiene polymer or a suitable grade of polyurethane etc and the bracket may be cast from a light alloy such as an aluminium alloy or a suitable hard and shock resistant polymer or engineering plastic such as acrylonitrile butadiene styrenes, polycarbonates or polyamides. The assembly is achieved by pushing the shock absorber into therecess 7 of the bracket and then the pivot is inserted into the bore 2 a of the shock absorber until the axle slides over theprotrusions 8 of the bracket. - The bracket is to be mounted on a sole plate of a roller skate or a skateboard with the pivot at an acute angle to the sole plate (a sole plate is shown in
FIGS. 13 and 14 , for example). - The assembly may conveniently be mounted on a sole plate for the skate but alternatively the bracket may be mounted directly to a sole of a boot of the roller skate or a sole plate may be incorporated in the boot, an example is shown in
FIGS. 19 and 20 . -
FIG. 3 shows an assembly andFIG. 4 the separated parts which are similar to those shown inFIGS. 1 and 2 and the same reference numerals are used for these.

The side plates haveflanges 10 a to enhance their holding action. Another difference is that thepivot 3 instead of being formed as a solid rod is formed as a folded sheet metal and theflange 14 has minor differences from theflange 4. (In the view ofFIG. 3 the shock absorber and embedded axle and pivot are not shown assembled for illustration value). The side plates span between two assemblies, and thus also set the two assemblies ready for mounting at the surfaces 11 a of the brackets to a sole plate or sole of a roller skate boot. The recess 12 in each bracket set the acute angle of the pivot to the plane in which the surfaces 11 a of the brackets lie and the plane of the sole plate/boot sole. The angle faces one way in one bracket and the other in the other bracket so that the axles turn in opposite directions when the skater leans into a turn and flexes the sole into the turn. -
