A cycle frame includes an upper tube joined at one end to a lower tube by a frontal part and joined at an opposing end to stays by a continuously formed connecting part. A front fork pivot housing is attached to a reduced thickness, core portion of the frontal part and a seat post housing, having a forked base, is secured to the connecting part. The core portion and the front fork pivot housing have complementary mating surfaces to enhance the structural integrity of the assembly. In a similar f...

A holding arrangement includes a pair of elongated branch members forming, for example, a support for a cycle rack, with a pair of links being arranged in a vicinity of lower ends of the branch members for connecting the branch members so as to enable a relative displacement between the branch members. An arrangement is disposed between the lower end portion and the upper end portion of the branch members for displacing the branch members from a closed position to an opened position and for appl...

A lockable toggle joint (4, 5) for a cycle rack with pair of scissor shaped branches (2, 3) and scissor joint (7, 71, 72) comprising suitably shaped holding means (8A, 8B) for the holding of the rack to a conventional trailer ball hitch (1) at the rear of an automobile and carrying means (2A, 3A) for the bicycles comprises a snaplock and interlock means (6) which is lockable.

Recumbent cycle (12) is supported by a pair of forward steerable wheels (16) and a single rear drivewheel (18) mounted on rear end portion of a frame structure (14) by a hub assembly (50) having an integral transmission and brake. A pair of side-mounted gimbal assemblies (170L, 170R) may be conveniently tilted laterally to steer wheels (16) in the same corresponding direction. The gimbal assemblies (170L, 170R) may be individually or in unison tilted in the forward direction to actuate the brake...

A refrigeration system is described in two preferred embodiments. In both embodiments, the refrigeration cycle includes a conventional compressor, condenser, expansion valve and evaporator. The receiver is not in the loop normally. In one embodiment, a pressure differential valve diverts subcooled refrigerant to the receiver only in response to a predetermined difference in pressure between the saturation pressure caused by the ambient surrounding the condenser, plus spring pressure and the pres...

A lockable toggle joint (4,5) for a cycle rack with pair of scissor shaped branches (2, 3) and scissor joint (7, 71, 72) comprising suitably shaped holding means (8A, 5 8B) for the holding of the rack to a conventional trailer ball hitch (1) at the rear of an autombile and carrying means (2A, 3A) for the bicycles comprises snaplock and interlock means (6) which is lockable.

It consists of a pair of brake arms provided with brake shoes, the distance between which can be freely widened or narrowed, arm mounting plates provided with support shafts to support brake arms and attached to a bicycle body, return springs which energize brake arms constantly in spreading directions so as that aforementioned brake shoes are separated apart from each other, and spring caps and tightening bolts. A return spring storage recess is formed around the support shaft and in the bossed...

To facilitate manufacture of lightweight bicycle carriers, in particular the attachment of supporting struts (6, 7) to a frame (1) having longitudinal support rods (3) for example formed of aluminum, the longitudinal support rods have injection-molded attachment elements (12) molded thereof, made of resiliently expandable material, with an open slit (18) extending to an opening (17) therein, permitting cross elements (10, 11) of the support struts (6, 7) to be snapped therein, the projecting por...

This invention concerns a derailleur for a cycle, comprising a yoke provided with a chain-guide pinion and a chain-tensioning pinion

The derailleur comprises a finger member which bears on a cam surface. The finger member is carried by an arm of a parallelogram structure. The cam surface is provided on the support of the derailleur. Preferably, the cam achieves a tri-dimensional guiding of the finger member which carries a rotary roller.
