Josef Ben-Alexander ( the Inventor ) 50 Aluf David Str. Ramat - Chen 52232 ISRAEL The present invention relates to roller skates and more particularly to an accelerating mechanism for such skates.

The evolution of roller skates during the past few years has changed from four wheeler heavy metal skates to shoe skates and on-line skates with better bearings, plastic wheels and other accessories.

The changes are mainly due to the increasing use of such skates. Regardless of the improvements in the skates, the standard motions of legs and body while skating have not changed.

Fast and powerful movements result in fast movement of the skates, however, fast and powerful movement cause quick fatigue to the skater.

It is thus an object of the present invention to provide an accelerating mechanism for roller skates.

C:\2main\D67\67856a.Doc - - It is a further object of the present invention to provide a mechanism which would assist and ease the use of roller skates.

According to the invention at least one wheel of the roller skate is provided with a free wheel gear being engaged with a toothed member which is fixedly connected to the skate in such a manner that by activating the foot the said toothed member would drive said wheel with the free wheel. Reciprocating movements of said member would accelerate the movement of the roller.

The toothed member could be of different configuration adapted to transfer the linear movement thereof to pivoting movement of the driving wheel.

The invention will now be described with reference to the annexed drawings in which: Fig. 1A is a side view of a roller skate provided with the accelerating mechanism according to the invention.

Fig. IB is likewise the roller skate demonstrating the manner of operating the mechanism.

C:\2main\D67\67856a.DOC - - Figs. 2A and 2B demonstrate a configuration of said mechanism.

Figs. 3A, 3B and 3C illustrate a further embodiment of said mechanism.

Figs. 4A and 4B illustrate yet a further embodiment of said mechanism.

Turning first to Figs. 1A and IB, a common roller skate which is normally made of two main parts, the upper part 1 which is the shoe and the lower construction 3 for the wheels of the roller.

As can be seen there is connected a tooth member 7 to the heel of the shoe 5 which is engaged with the gear 9 of the rear wheel 10 of the roller.

In the present embodiment the shoe part and the construction of the wheels are pivotally connected at 11 so that the heel part could be lifted and pushed down again in a reciprocating manner. Due to the fact that the tooth member is engaged with the gear, a pivoting motion will occur when the heel is pushed down. Spring 12 will cause and ease the lifting of the heel. Such lifting action could be performed even though member 7 and gear 9 are engaged, due to the free wheel mechanism of the rear wheel 10.

C:\2main\D67\67856a.DOC - - At the rear part of the shoe there is provided a fastener or hook 14 which enables immobilizing the shoe part and the roller skate is used in the usual common manner.

As can be seen in Figs. 2A and 2B of the drawing, the construction differs slightly from the one depicted in Figs. 1A and IB, nevertheless, the mode of operation is almost the same.

In the embodiment seen in Figs. 3A, 3B and 3C the tooth member is stationary, while the rear wheel 10 of the roller is so mounted to enable its up and down movement within a slot 15 provided in the support of the wheel.

Fig. 3C illustrates the mechanism of the spring which enables the reciprocating movement of the wheel.

Figs. 4 A and 4B illustrate a further embodiment where like the one seen in Figs. 3A, 3B and 3C the rear wheel is mounted on suspension member 17 pivotally connected at 19 while toothed member 7 is connected at 20. The mode of operation is similar to the other embodiments. The reciprocating movement of the wheel will be caused by the mere lifting of the heel.

C:\2main\D67\67856a.DOC - - It has been found that the rear wheel is the preferred one for mounting the accelerating mechanism, however, it is within the scope of the invention to mount the mechanism in any other wheel, or more than one.
