Abstract

A skate having a damping mechanism secured thereto to reduce the harmful vibrational stress from being transmitted through the skate to the wearer'"'"'s leg.

Claims

1. A roller skate that includes

a boot that further includes a shell for embracing the foot and lower leg of a wearer and a sole plate secured to the bottom of the shell,

a wheel frame secured to the sole plate for rotatably supporting a plurality of wheel whereby the skate can move in rolling contact over a contact surface,

a damping system that includes an elongated flexible member that is secured at one end to the boot and a weight means of predetermined mass secured to the opposite end of the flexible member so that the weight means is caused to vibrate at the end of said member as the wheels move over a rough surface to reduce the effects of contact surface induced oscillations.

2. The roller skate of claim 1 wherein the weight means is removably secured to the free end of said flexible member whereby the mass of the weight means may be changed to increase or decrease the effect of damping.

3. The roller skate of claim 1 that further includes adjustable means for securing the weight to the free end of said flexible member so that the weight can be selectively positioned along the length of the flexible member to change the damping effect of the system.

4. The roller skate of claim 1 wherein said one end of the flexible member is secured the sole plate of the boot.

5. The roller skate of claim 1 wherein said one end of the flexible member is secured to the shell of the boot.
