JPH1085385A - Brake for in-line type roller skates and skates provided with the brake - Google Patents

Abstract

PROBLEM TO BE SOLVED: To avoid transmission of vibration to skater's legs at the time of braking, by installing a shock absorbing member between the load bearing structure and the pad in the in-line type roller skates having a brake pad and a load bearing structure to which the pad is fitted. SOLUTION: The in-line type roller skates are fitted to the wheel fittings for front/rear wheels, having a brake at the rear side. This brake includes a load bearing structure 5 to where the brake pad 6 is fitted. This load bearing structure 5 is provided with two arms 5a and 5b connected to the structure via a curved wall 5c to form a U-shape. Each arm 5a and 5b is fitted to each free end in a joint fashion with the rear wheel shaft as a center which is then fixed to the wheel fittings via a fixing member, respectively. The shock absorbing member 15 is inserted into between the load bearing structure 5 and the pad 6. This has a layer 16 provided with the surfaces 17a and 17b facing each other, forming a U-shape together with the arms 18a and 18b.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a skate shoe brake specially designed for in-line roller skate shoes as defined in the general part of the independent claim.

[0002]

BACKGROUND OF THE INVENTION There are two types of pads in this particular field of technology, one with a load bearing fixed to a wheel mount for a skate and one with a structure that pivots on the mount. Brakes are known.
The disadvantage encountered with both types of brakes lies in the unwanted vibrations that occur on the pads during braking of the skate. This unwanted vibration is generated primarily due to the non-uniformity of the braking surface of the pad, which is biased toward the ground during braking and wears out over time as it is used. These vibrations are transmitted through the pads to the load-bearing structure and from there to the skater legs, which is quite troublesome.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a brake for a skate designed to overcome any disadvantages raised in the prior art.

[0004]

SUMMARY OF THE INVENTION This problem is solved by the present invention by a brake formed according to the claims.

[0005] The features and advantages of the present invention will become more apparent by describing in detail preferred embodiments, with non-limiting examples illustrated in the accompanying drawings.

[0006]

DETAILED DESCRIPTION OF THE INVENTION In FIG. 1, a brake, generally designated by the reference numeral 1, is mounted on a wheel mount 2 of an inline roller skating shoe 3, only a part of which is shown. The front and rear wheels 4 having a single row and having parallel rotation axes are rotatably mounted on the wheel mounting body 2.

The brake 1 includes a load supporting structure 5 to which a brake pad 6 is attached.
Has a surface 6a that is biased toward the ground to brake the skate, and the brake pad 6 is mounted to the load-bearing structure 5 in a detailed manner described below.

The load-bearing structure 5 comprises two arms 5a, 5b provided side by side and connected by a curved wall 5c and is substantially U-shaped. Each arm 5a, 5
b are articulated by their respective free ends around the axle of the rear wheel 4 and are fixed to the wheel mount 2 at a third point by fastening members 7. The brake 1 is a patent application of the applicant for adjusting the rotation of the load-bearing structure 5 with respect to the rear wheel mounting body 2.
It has a device of the type described in O.PD96A000118. The device has an adjusting strut screwed at one end into the rear wheel mount 2 and at the opposite end into a ring nut 8, which is housed in a fastening member 7. A detailed description of the adjustment device is contained in the aforementioned patent application.

The load-bearing structure 5 also comprises a lip 9, preferably formed integrally with said structure. Lip 9
Has a U-shape, and is provided at its free ends with protrusions 10 whose function will be described in detail below.

The pad 6 has a partial element 11 for attaching the pad 6 to the load supporting structure 5, and the partial element 11
A set of grooves 12, oppositely symmetrical channel cross-sections, for interlocking engagement with two juxtaposed arms of the lip 9 for removably connecting the load bearing structure 5 to the pad 6; 13 inclusive.

One shock absorbing member indicated by reference numeral 15 is:
It is inserted between the load supporting structure 5 and the pad 6. The shock-absorbing member 15 has a layer body 16 provided with facing surfaces 17a, 17b, and has a horseshoe shape with two arms 18a, 18b.

Each arm 18a, 18b of the layer body 16 is accommodated in a groove 12, 13 respectively, with the surfaces 17a, 17b facing the lip 9 and the pad 6, respectively.

The grooves 12, 13, the lip 9, and the layer body 16
Has a cross-sectional dimension such that the pad 6 is forced to undergo incidental deformation due to the flexibility of the layer body 16. This allows the pad to be clamped to the structure 5. The two projections 10 which engage the corresponding recesses of the grooves 12, 13 when the lip 9 is fully fitted in contact with the pad 6 also cooperate with this clamp.

[0014]

The shock absorbing member 15 is made of an elastic material having a larger elastic modulus than the pad. Thus, it serves to absorb or at least dampen the vibrations that occur on the pad 6 during skating, mainly due to the non-uniformity of the braking surface 6a, which wears constantly with use. The shock absorbing member 15 can be formed from a variety of materials having different elastic properties, depending on the specific requirements of the user or the nature of the running surface intended for the skate.

It should be noted that both the shock absorbing member 15 and the pad 6 can be changed quickly and easily by the user himself by providing the interlocking connection described above.
