Abstract

The invention relates to a brake for inline skates using an additional wheel mounted at the rear. This additional wheel can be moved upwards and when placed under pressure, presses against a brake block (8). The wheel moves along grooves or slots (5) provided in the underframe, pullback springs (6) also being provided in said grooves or slots (5). It is also possible to arrange this brake block so that it too is moveable, so that when the additional wheel is placed under pressure said brake block also presses on the wheel second from the rear at the same time, or presses an additional brake block onto the wheel second from the rear via a connection or a lever. A rim braking action in the wheel interior is also a viable alternative to the braking action on the periphery of the wheel, that is the wheel tire.

Claims

7 CHANGED CLAIMS [received by the International Bureau on 8 October 1998 (08.10.98); original claims 1-12 replaced by amended claims 1-10 (2 pages)]

1. brake for inline skates in the form of an additional, brakable wheel, which is provided behind the normal, usually three to four wheels, characterized in that the latter wheel is displaceable against the top and selective load by depressing the Shoe in the heel area with simultaneous increase of the toe area as a result of the shift occurring thereby presses on a brake pad (8) or a brake pad, so that at least in this wheel, a braking effect occurs; that the axis or the hubs (3) of this rearmost wheel is (are) supported on both sides in parallel slots provided in the chassis, so that it is guided and the displacement is in a precisely defined direction he follows; that this wheel is pushed back into the starting position with relief by means of two return springs (6); and that the recoil springs (6) are provided within the slots (5).

2. Brake according to claim 1, characterized in that the brake pad or the brake pad is displaceable at the rearmost wheel and acts in addition by braking in addition either directly on the second-most rear wheel or via a direct connection or a lever another brake pad or brake pad against pushes the second-most distant wheel.

3. Brake according to at least one of claims 1 and 2, characterized in that the brake pad is a total of something compressible by the wheel not directly contacting part another, compressible material is provided as in the contact area to the wheel, or that he on another Is steamed or hard sprung, so that the brake pressure is not transmitted directly, but with distance-dependent strength.

4. Brake according to at least one of claims 1 to 3, characterized in that the braking at the periphery of the wheel 8 and the wheels takes place by the brake pad presses on the tire.

5. brake according to claim 4, characterized in that the brake pad in the contact area to the wheel is formed around and this somewhat adapted and that this rounding has a slightly larger radius than the wheel.

6. brake according to at least one of the Asprüche 4 and 5, characterized in that the brake pad or the brake pads

Metal, preferably made of aluminum.

7. Brake according to at least one of claims 4 and 5, characterized in that the brake pad or the brake pads consist of a rubber-like material.

8. Brake according to at least one of claims 1 to 3, characterized in that the braking takes place in the interior region of the wheel or the wheels by the latter rims, preferably made of metal, and a circular cavity are provided and by a Brake pad presses on these rims.

9. brake according to claim 8, characterized in that the brake pad from the inside outwards, so towards the Radperipherie out, presses.

10. Brake according to claim 8, characterized in that the brake pad from the outside inwards, ie towards the wheel center, presses.

DECLARATION REFERRED TO IN ARTICLE 19

Based on the research, it has been found that individual ideas according to the invention are already known, but that they are not provided for in the combination according to the invention. As a result, the main claim 1 had to be restricted by integrating the original claims 2 and 3. Accordingly, the description or its reference to the prior art to modify.

Known according to US Pat. 5,551,712 namely brake wheels whose axes are slidable within slots or grooves against above and provided with return springs. As is apparent from the description, however, the return springs are provided there laterally of the chassis and not within the slots or grooves.

The same applies to WO 93/16773, where indeed a possibility is also mentioned to provide two return springs pressing directly onto the axle of a brake wheel (FIGS. 12-14). However, these are appropriate within separate submissions. In addition, there is the braking device as a whole rather complicated and does not suggest the proposed invention in any way.

Although the attachment of springs within the slots or grooves provided for displacement of the wheel axle is known from US Pat. No. 5,511,803, the spring pressure only takes place in the opposite direction, ie not away from the brake pad, but towards the brake pad (FIG ).

In US Pat. No. 5,478,094, on the other hand, there is no displaceable, but a pivotably arranged brake wheel, which does not correspond to the principle according to the invention

The idea according to the invention makes possible an extremely simple device which obviously can not be deduced from the ideas already known, since it can not be found among the published design possibilities.
