  • Patent number: 4671506
    Abstract: An amusement device comprises a portable rotary carrousel which is occupant propelled. More particularly, the device comprises a housing anchored angularly on a base and an axle extending upwardly therefrom to accept and support an inclined carrousel. Individuals seated at opposite ends of the carrousel cause the axle to rotate by shifting their weight. Alternatively, the device may include a conventional automobile rear end differential to transmit rotary motion for operation of an external structure. The differential is anchored angularly on the base which has the housing and axle extending upwardly therefrom to accept and support the inclined carrousel. The differential may be operatively connected by a drive shaft, transmission, and universal joint to transmit rotary motion produced by the inclined carrousel for operation of the external structure.

  • Patent number: 4666147
    Abstract: An invert diving platform affixed to the structure of a common pool ladder anchored to the deck of a pool for providing an elevated platform above the water level for diving. The platform is rigidly attached to the parallel railings of the ladder in a generally horizontal position. The platform is rigidly attached to the curved rungs by two pair of opposed clamps attached to opposed ends of the platform. The clamps are vertically adjustable on the railings of the ladder to allow adjustment of the height of the platform. The clamps attach to railings having various shapes, dimensions and angles to provide rigid support for the platform. An incline plane may be attached to the platform at an angle descending into the pool to provide a slide. A bracing member is connectable to the steps of the pool ladder to provide horizontal stability.

  • Patent number: 4665388
    Abstract: A signalling device for weight lifters performing exercises involving bending of the knees. The signalling device is provided with mercury switch for sensing deviation of the axis of the portion of the leg to which the device is attached and a buzzer or other signalling device which signals the lifter when that portion of the leg has deviated from the vertical by a preselected amount. The amount of deviation from the vertical required to activate the signalling device may be varied by an optional angle adjustment. The signalling device allows a weight lifter to exercise properly, but effectively, without risking injury.

  • Patent number: 4640301
    Abstract: A locking assembly is disclosed which is suitable for releasably locking two articulated pivoting members in a fixed position with respect to each other. The locking assembly comprises a spring biased reciprocating latch, a plunger attached to the latch, and a catch plate adapted to rotate into locking engagement therewith. The plunger and latch are preferably integral with each other, so that the latch contains a minimum number of moving parts. The latch is designed so that simple palm pressure will cause it to disengage from the catch plate, to permit the pivoting members to move with respect to each other. The present locking assembly is of simple design and inexpensive manufacture, and is durable in use. The locking assembly is particularly applicable for use in invalid appliances such as collapsible walkers, where the users have limited manual dexterity.

  • Patent number: 4640508
    Abstract: A precessional exercising device utilizing a housing containing a spinning mass which forms the rotor of a motor for spinning the mass. The housing is coupled to a remote handle by a linkage permitting rotation of the handle about two mutually orthogonal axes. When the handle is rotated about one or both of said axes, the corresponding angular movements are transmitted to the spinning mass and its spin axis is rotated accordingly, causing the generation of precession torques which are coupled back to the handle via the linkage to produce an exercise effect when the handle is held so as to resist said torques.

  • Patent number: 4630626
    Abstract: An improved crutch tip construction. The crutch tip is formed of a resilient material and has an upper tubular stem portion formed with an axial recess and a lower enlarged head. A concave metallic socket with a reversed upper lip portion is disposed at the bottom of the recess and the lower end of the crutch bow is engaged with the socket. The lower surface of the head of the tip is generally convex and is formed with a plurality of concentric grooves. The combination of the metal socket with the convex lower surface of the head provides a greater surface area of contact between the tip and the supporting surface during use, thereby achieving greater safety for use of the crutch.

  • Patent number: RE32815
    Abstract: A height adjustable crutch having a bow comprised of a pair of hollow tubular vertical members which are angled downwardly toward each other with their lower extremities aligned in spaced-apart parallel relationship in their hollow tubular condition. A hollow tubular carrier is disposed between and in abutment with these tubular extremities and the three members are secured, as by bolt through them in the upper area where they are in abutment, and by an integral encircling element at their lower extremities, the encircling element being pinned at externally diametrically opposite points of abutment of such element with the extremities of the tubular members. The tubular carrier is orificed at selective intervals and receives an orificed telescoping foot member provided with at least one radially outwardly spring biased detent. This detent serves to lock the foot member in any disposition relative to the carrier when the detent is passed through any registering orifices of the carrier and foot member.
