Abstract

A therapeutic roller apparatus that includes a rigid plastic roller member and a soft foam material sleeve that is adapted to fittingly mount about the rigid plastic roller member. The rigid plastic roller member preferably also has an inner tubular passage for fittingly receiving a vibration assembly. The vibration assembly includes, inter alia, an energy driven motor, preferably driven from an array of batteries and a weight that is coupled with the motor. The weight and motor together, when operated, provide a vibratory effect that is transferred through to the outer soft foam material sleeve.

Claims

1. A therapeutic roller apparatus comprising:

a rigid plastic roller member;

a soft foam material sleeve that is adapted to fittingly mount about said rigid plastic roller member;

only one off center axis weight;

a vibration assembly including an energy driven motor coupled with said off center axis weight that together, when operated, provides a vibratory effect at the soft foam material sleeve;

said rigid plastic roller member including an outer tubular member having a predetermined length, an inner tubular member having a predetermined length that is substantially the same as the length of the outer tubular member, and separate spoke pieces disposed respectively at opposite ends of the tubular members and each including a plurality of radially extending spokes having respective ends fixedly secured to the outer tubular member and the inner tubular member opposite ends and constructed and arranged so that the inner tubular member is coaxially disposed within and relative to the outer tubular member;

said vibration assembly including a main tubular body that is constructed and arranged to be fittingly received within the inner tubular member of the rigid plastic roller member, and that has inner ribs that separate the interior of the main body into separate compartments;

wherein the main tubular body of the vibration assembly includes a pair of semicircular main body halves that are joined to form the separate compartments and that have respective one and other ends;

said main body halves having an enclosing end cap at the one end thereof adjacent to the off center axis weight and for enclosing the off center axis weight;

said main tubular body having a length less than the length of the rigid plastic roller member so as to dispose the motor that is within the main tubular body member substantially at a midpoint of the rigid plastic roller member;

said vibration assembly further including a shaft that intercouples the weight and motor, a plurality of series connected batteries, and a switch assembly for selectively operating the motor;

at least one bushing disposed in the main body and a bushing holder for supporting the bushing from the shaft;

said bushing holder received between the main body halves, supported on the vibration assembly shaft and disposed between the motor and off center axis weight;

said switch assembly including an end cap disposed at the other end of the main tubular body, a switch, a switch holder, and a switch actuation button comprised of a two pole on/off switch having a first selected position hit to turn the motor on and a second selected position subsequently hit to turn the motor off.

2. The therapeutic roller apparatus of claim 1 wherein the ribs include ribs for supporting the bushing holder.

3. The therapeutic roller apparatus of claim 2 wherein separate compartments are defined by a rib that separates a battery compartment from a motor and weight compartment.

4. The therapeutic roller apparatus of claim 1 wherein the weight has a center hole therein and an off center weight distribution.

5. The therapeutic roller apparatus of claim 4 including a pair of bushings and associated bushing holders.

6. The therapeutic roller apparatus of claim 5 wherein the series connected batteries are disposed adjacent to the switch assembly end cap.

7. The therapeutic roller apparatus of claim 6 wherein the bushings support the shaft and are spacedly disposed between each other and also spacedly arranged between the motor and weight.

8. The therapeutic roller apparatus of claim 7 wherein the weight is spacedly disposed relative to the end cap along the shaft.

9. The therapeutic roller apparatus of claim 8 wherein the switch holder includes holder halves.

10. The therapeutic roller apparatus of claim 9 wherein the switch assembly also includes a contact plate and spring for biasing the switch to a more distal position.

11. The therapeutic roller apparatus of claim 1 wherein the soft foam material sleeve comprises a neoprene sleeve.
