The disclosure herein relates to a rotational connection assembly. More specifically, the present disclosure relates to a rotational connection assembly that has at least three layers of support. The disclosure herein may be used to connect two objects while allowing for a 360 degree rotation between the two objects. For example, the rotational connection assembly may be used to attach handlebars, fork, or headtube to a scooter, a bicycle, an elipticycle, a unicycle, a motorcycle, all terrain vehicles (ATV), quads, jet skis, or snow mobiles. The disclosure herein also relates to a convertible wheel assembly. More specifically, the present disclosure relates to a wheel assembly that can be converted from one wheel to two wheels or to three wheels. For example, the convertible wheel assembly may be used on a scooter, a skateboard, a skate, or a bi/tri-cycle.

An adjustable handlebar riser assembly has an outer member, an inner member, a pin, a retainer member and a locking member. The inner member and the outer member have mating flat-bottom V-shaped faces. The inner member slides at least in part within the outer member. Each of the outer and inner members has at least one aperture through their flat-bottom V-shaped faces. The pin is inserted in an aperture of the outer member and in an aperture of the inner member. The retaining member is connected to the pin at one end while the locking member is connected to an opposed end of the pin. The locking member can exert a tension on the pin, pressing the outer member onto the inner member for locking these members at a selected position relative to one another.

A wheel hub assembly for a scooter of the type having a handle bar, front and rear wheels and a rider's platform extending therebetween, the hub assembly (comprising; a first part comprising an annular body and a second part comprising an annular body and opposing the first part. An annular ri.ro is insertable in an internal space defined by a wheel, and having an. internal space which receives and retains therein a wheel bearing. The annular body of the first part and annular body of the second part mutually engage in opposing relationship via an opening in the bearing. The wheel hub is characterised in that it leaves a clear opening through the central axis of the wheel without requiring a wheel axle.

A structure of a bicycle (10) comprising a frame (1), a rear wheel (3) pivotally connected to the frame (1), a front fork (4) rotatably arranged about a steering axis (4'), a front wheel (5) rotatable with respect to the fork (4), a handlebar (6) integral to the fork (4) and configured for being gripped by a rider. The handlebar (6) comprises a rider-propelled mechanism (20) that can be operated by the rider by one's own arms in order to rotate the front wheel (5), comprising a shaft (21) rotatable with respect to the handlebar (6), a transmission means (30) for transmitting the rotational movement from the shaft (21) to the wheel (5); a first and a second crank (24,25) integral to respective ends (22,23) of the shaft; two handles (26,27) rotatable with respect to the cranks (24,25), so that the rider, gripping the handles (26,27), can cause the shaft to rotate (21) by rotating the cranks (24,25), and can cause the fork (4) to rotate about its steering axis (4'). The bicycle (10) also comprises a brake (60) associated with at least one handle (26,27) comprising a brake element (61) for one of the two wheels (3,5), in order to block the wheel (3,5) by switching from a release configuration to a configuration of friction with the wheel (3,5); a cable (63,64) for operating the brake element (61) and a pull means of the cable (63,64). In a first aspect of the invention a means is provided (40) for causing a relative rotational movement of crank (24) with respect to the shaft (21) in order to bring it from a first configuration (A) shifted by 180° with respect to the other crank (25) to a second configuration (B) substantially aligned with the other crank (25), through a rotatable joint (95,45) arranged between the shaft (21) and the crank (24), and through unlock/lock means (41) of the joint (95,45), which can be operated by the handle (26) and to unlock/lock the rotation between the shaft (21) and the crank (24), so that the rider can bring the crank (24) from the first to the second configuration and vice-versa, by acting on the handle (26) only, In another aspect, a first a second cable (63,64) are provided, and the pull means comprises a first and a second pull means (80,73) connected to each other to respective ends of the second cable (64), which has another end (64a) pivotally connected to the first pull means (80); the cables comprise engagement means (74) arranged on the handles (26,27) and configured to pass from a normal riding configuration (E), where the handle (26,27) is disengaged from the pull means (73), to a braking configuration (F) where the handle (26,27) is integral to the pull means (73), whereby rotating the handle (26,27) is operate the second pull means (73) and so pulls the second cable (64),
摘要:
The present invention relates to a front-wheel-drive bicycle. The front-wheel-drive bicycle according to the present invention also enables rear-wheel-drive using pedals, and enables front-wheel-drive to be carried out by enabling a rider to repeat the rotation of handlebars in the right and left directions. The rightward and leftward rotation of the handlebars is delivered to the front wheel via a front-wheel-drive unit to thus rotate the front wheel in the forward direction. The position of a joint-adjusting unit is adjusted so as to implement the operation of the handlebars for the front-wheel-drive or for changing direction. According to the present invention, front-wheel-drive may be performed without a separate auxiliary driving apparatus, and the operation of handlebars for front wheel drive and the operation of the handlebars for changing direction may be performed independently from one another.
