A swing machine includes a casing having a sliding member movably engaged with a rail and the sliding member is driven by a block eccentrically connected to an output shaft of a motor. A support member is connected to a top of the sliding member. A first protrusion extends from a side of the sliding member and a limitation member located in the casing has a wave-shaped slot in which the second protrusion is movably engaged.

A swing arm for moveably fitting wheels onto a support element, comprising at least two hollow arm parts, hollow-moulded using the internal high pressure moulding method. One of the arm parts has a connecting projection which is inserted into and fixed in an end section of an other of said arm parts. An exterior peripheral surface of the projection corresponds to an interior peripheral surface of the end section of the other arm part so that the one arm part can be connected to the other arm par...

There is disclosed an infant sling which is formed as a generally U-shaped band of flexible sheet material having its upper ends attached to a support. The support can be a vest worn by an adult to provide an infant carrier, or can be a support ring which is suspended from a supporting structure to provide an infant swing. The support ring has substantially the same diameter as the lateral dimensions of the infant. The support ring protects the infant's head, and supports the sides of the sling ...

A motorized swing is set forth including a spaced plurality of support bases and posts with support shafts horizontally oriented between the posts and securing a child's swing in a suspended fashion therefrom. Adjacent each post and spaced from the swing along the support shaft is a motor housing including a drive motor and gear drive with a downwardly depending pivot control arm directed orthogonally therefrom. Each pivot control arm is formed of a lower "L" shaped arm and an upper linear link,...

A swing-in-swing-out chair apparatus for a bathtub-showerstall unit, or the like, and comprising a bar adapted to be disposed on the floor adjacent the outer periphery of the bathtub, an upright post extending from the bar to a position above the upper edge of the bathtub and pivotal about its own longitudinal axis, a seat support arm assembly secured to the upright post and movable therewith, a seat member secured to the support arm assembly and movable between an exterior position with respect...

A training aid for teaching batters how to swing properly. The aid resembles a baseball bat which has a front portion which has been flattened, and an angled device has been attached to the handle. The angled portion has a flat portion which is not quite parallel with the flat portion on the front of the bat.

This invention is for someone who wants to exercise, self-teach or teach the golf swing. The object is to make contact with the "sweet spot" portion center of the club head. Using this will tone the rhythm of his or her body to a consistent swing posture. The results will lead to straighter, longer drives. This unit can be used as a warm up prior to the golf course or driving range. What helps make this a reality is the ball will project a material that will leave a mark on the club head, indica...

A swing exerciser especially suitable for golf exercise uses a handle and cord arranged to move a resistance trolley down a track positioned on the golfer's back swing side. A spring and pulley arrangement resists movement of the trolley down the track, and movement of the handle by the golfer through the curve of a golf swing forces the trolley down the track so that the golf exerciser must overcome the resistance while swinging the handle to strengthen the muscles needed for powerfully hitting...

An apparatus for use in training proper swing mechanics, for use in connection with golf, baseball, tennis, or similar sports. The device includes a sheath, which has an cushion member attached to a concave inner surface for user comfort. The apparatus is releasably attachable to a user's legs or hips by a pair of straps incorporating hook and loop fastening material, and includes a projecting rigid support member extending normal to the sheath outer surface with a weight member having a soft ou...

A linkage assembly includes a first link connected at a first point to a translation mechanism attached to a support structure. The translation mechanism is arranged to allow the first point of the first link to translate along a substantially straight axis. A second link is pivotally connected at a first point to the support structure, and at a second point to the first link. A second point of the first link travels on or near an arc of substantially constant finite radius when the first link p...
