Abstract

This invention is directed to in-line roller skates. More particularly, this invention pertains to shock absorbent in-line roller skates wherein the wheels are resilient mounted to navigate over rough, bumpy surfaces. An in-line roller skate comprising: (a) a boot with a heel and toe adapted to receive a foot of a skater; (b) a first wheel supporting rail means secured to an underside of the boot and extending from the heel to the toe; (c) a second wheel supporting rail means secured to an underside of the boot, and extending from the heel to the toe adjacent and generally parallel to the first rail means; (d) a plurality of wheel means mounted in tandem in a line between the first and second rail means, the wheel means being respectively connected to the first and second rail means by respective axle means and bearing means; and (e) a plurality of resilient shock absorbing means located between the respective axle means and bearing means and the rail means to enable the respective wheel means to move under force individually upwardly or downwardly relative to the first and second rail means.

Claims

1. An in-line roller skate comprising:

(a) a boot with a heel and toe adapted to receive a foot of a skater;

(b) a first wheel supporting rail means secured to an underside of the boot and extending from the heel to the toe;

(c) a second wheel supporting rail means secured to an underside of the boot and extending from the heel to the toe adjacent and generally parallel to the first rail means;

(d) a plurality of wheel means mounted in tandem in a line between the first and second rail means, the wheel means being respectively connected to the first and second rail means by respective axle means and bearing means; and

(e) a plurality of resilient shock absorbing means located between the respective axle means and bearing means and the rail means to enable the respective wheel means to move under force individually upwardly or downwardly relative to the first and second rail means, said resilient shock absorbing means being arranged in pairs for each wheel, axle and bearing means, and the resilient shock absorbing means being mounted in respective vertical elongated cavities in the first and second rail means, each resilient means having a crescent shape, the axle means fitting in the concave curves of the crescents whereby the axles are positioned at a first elevation when the concave sides of the crescents face upwardly and are positioned at a second lower elevation when the concave sides of the crescents face downwardly.

2. A roller skate as claimed in claim 1 wherein there are at least three wheel means and the first rail means and the second rail means include at least three respective resilient means and the at least three wheel means are rotationally mounted in the respective resilient means.

3. A roller skate as claimed in claim 1 wherein the resilient shock absorbing means are removable and invertible resilient plugs which are positioned in the respective cavity means in the first rail means and the second rail means, the resilient plugs impinging on the axle and bearing means for each respective wheel means, and absorbing compression force when the respective wheel means moves upwardly, and dispensing compression force when the respective wheel means moves downwardly.

4. A roller skate as claimed in claim 3 wherein the first rail means and the second rail means have formed therein, in association with the respective cavity means, axle wells, which permit the axles to move upwardly or downwardly in relation to the first and second rail means.

5. A roller skate as claimed in claim 1 wherein the respective resilient means are held in place by respective removable washer means which fit about the respective axle means.

6. A roller skate as claimed in claim 5 wherein the respective resilient means are held in place by respective spacer sleeves which fit about the respective axle means on a side of the resilient means opposite to the washer means.

7. A roller skate as claimed in claim 1 wherein at least one reinforcing web is located between the first and second rail means.

8. A roller skate as claimed in claim 1 including a releasable wheel stop located between the underside of a toe of the boot and the top of a front wheel of the plurality of wheels.

9. An in-line roller skate comprising:

(a) a boot adapted to receive a foot of a skater;

(b) a wheel mounting means secured to the underside of the boot, longitudinal with the boot, and having an elongated longitudinal wheel receiving Cavity therein;

(c) a plurality of wheels rotatably mounted in series within the wheel receiving cavity and longitudinal alignment with one another;

(d) a releasable wheel rotation stop means located between the underside of a toe of the boot and above a forward wheel of the plurality of wheels, said wheel rotation stop means being movable so that it can impinge against a wheel to retard rotation of the wheel.

10. A roller skate as claimed in claim 9 wherein the wheel stop means is movable between a first position wherein the stop means is free of the forward wheel and permits the forward wheel to rotate and a second position wherein the stop means abuts the forward wheel and prevents rotation of the forward wheel.

11. A roller skate as claimed in claim 10 wherein the wheel stop means has releasable lock means which enables the stop means to be locked in a first or second position.

12. A roller skate as claimed in claim 9 wherein the wheel rotation stop means is slidably mounted on the underside of the toe and is movable horizontally between a first forward position whereby the wheel rotation stop means does not impinge on a front wheel, and a second rear position whereby the wheel rotation stop means impinges on the front wheel and thereby stops rotation of the front wheel.

13. A roller skate as claimed in claim 12 wherein the wheel rotation stop means has a protrusion on each lateral side thereof, said protrusions slideably moving in respective horizontal slots on each lateral side of the wheel mounting means.

14. A roller skate as claimed in claim 12 wherein the wheel rotation stop means has a releasable lock means which enables the stop means to be releasably locked in a forward wheel-free position or releasably locked in a second rear position whereby the front wheel is prevented from rotating.
