Abstract

Improved roller skates which would be provided with means enabling only unidirectional movement of the skates. At least one roller of the skates is provided with such means which would enable only forward movement of the skate and would prevent rolling back.

Description

IMPROVED ROLLER SKATES

The present invention relates to skates and more particularly to in-line skates known as "Rollerblades" (T.M.) .

Skates of the kind mentioned were developed as an off¬ season training tool for hockey players but were quickly adapted by all kinds of skaters for their training and shortly thereafter by the public for recreation, fitness and leisure time occupation.

Today, in-line skating sports such as in-line hockey, in¬ line racing and street style skating are rapidly gaining popularity.

It is an object of the present invention to provide improved in-line roller skates.

It is a further object of the present invention to provide in-line roller skates which would enable the skater to advance quicker and better.

It is yet a further object of the present invention to provide in-line roller skates which would enable the skater to skate uphill without difficulty.

According to the invention the rollers will be provided with means enabling only unidirectional movement of the skates thus achieving the following advantages: The skater will skate in a more convenient manner.

The power invested by the skater for forward movement will be lessened. No energy for preventing back rolling will be wasted.

The forward rolling could be faster. Uphill skating will be easier as no effort will be required for the prevention of rolling back. On the whole, the learning of skating would be easier.

iv

In accordance with the invention there being provided^in- lii'β skates at least one wheel (roller) is provided with me ns adapted to enable unidirectional revolving of said wlieel.

Tlie invention will now be described with reference to the nnexed drawings in which:

Fie 1 is a side schematical illustration of an in-line roller skate provided with means enabling only u; idirectional revolving of the rear wheel (roller) of t.,-j skate.

Fig. 2 is an embodiment where two wheels are provided with such means.

A conventional roller skat comprises a shoe proper 1 to the sole of which there is rigidly connected the skate 2 which comprises a plurality of wheels (rollers) 3. As can be seen in the accompanying schematical Fig. 1 the wheels, preferably the rear one, is provided with ratchet-like means 4 which would prevent the anti-clock¬ wise rotation of said wheel namely only clockwise rotation is possible. Said means includes a toothed wheel 5 connected to wheel 3 a tongue member 6 i.e., in contact with toothed wheel 5 and would prevent the anti-clockwise rotation.

The embodiment illustrated in Fig. 2 comprises the shoe 1 to the sole of which is fixedly connected a plate member 7 provided with two hook-like extensions 8. There is further provided a second plate 9 to which the rollers 3 are connected. Intermediate plates 7 and 9 are placed ball bearings 10.

Plate 9 is slidably mounted to plate 7 and shorter than plate 7 which enables linear movement of one plate relative to the other. The smooth movement of said plates is achieved by means of ball-bearings 10.

During the forward movement of the skate, plate 9 abuts against plate 7 at 11, while when the skate tends to move backwards plate 9 will abut against plate 7 at 12 and consequently hook member 8 would engage toothed wheel 5 and prevent back revolving of the wheel.

The above example of unidirectional revolving means is given only by way of example. It is within the scope of the invention to provide the wheel of a given skate with different means adapted to be used with such rollers.

Claims

CLAI S :

1. A roller skate of the in-line kind, at least one wheel (roller) of which is provided with means adapted to enable only unidirectional revolving of said wheel.

2. A roller sake as claimed in claim 1 where at least one roller is provided with a toothed wheel.

3. A roller skate as claimed in claim 1 and 2 where a ratchet-like arrangement enables only unidirectional rotation of said roller.

4. A roller skate as claimed in claim 1 and 2 where the sole of the roller shoe is made of two parts slidingly connected.

5. A roller skate as claimed in claim 4 where ball¬ bearings being provided intermediate said two part sole.

6. The roller skate as claimed in any of the above claims substantially as hereinbefore described and illustrated.
