摘要:
A ride-on vehicle (10) for children having a chassis (12), a plurality of wheels (14) attached to the chassis (12), and a steering mechanism (18), the vehicle includes a molded plastic footrest (40) having a body portion (44) and an end portion (50). The footrest being laterally slidable between a retracted position wherein the body portion is situated substantially within the chassis (12), and an extended position wherein at least part of the body portion is laterally disposed with respect to the chassis (12). In the extended position, the end portion (50) is a greater lateral distance from the chassis (12) than when the end portion (50) is in the retracted position. The vehicle (10) also has a detent mechanism (54) arranged to releasably hold the footrest in the retracted position and the extended position. The chassis (12) can include a channel (20) in which the footrest is laterally slidable.

摘要:
A scalable high-performance bouncing apparatus provides convenient access to an internally mounted compound tension spring (180). Semi-mounted internal storage of disengaged tension elements may be provided. The tension elements (180) may be engaged or disengaged through an access feature (320) such as a slot in the apparatus frame. A user's finger or tool (2020) may be employed to effect engagement/disengagement. Alternatively, the apparatus may include mechanical components capable of effecting engagement/disengagement. The tension elements may also be part of a cartridge unit (2200) that can be wholly removed from the apparatus for engagement/disengagement. The assembly may also include a torque-transmitting bearing (170) for improved high performance operation.
摘要:
The invention relates to a device for improving the spinal column muscles by training said muscles with oscillations without extreme swinging movements. Said device has a seat carrier (16) which is mounted to provide movement about at least one pivot (5, 6) in a number of dimensions, and the device has drive means used to supply multidimensional movement pulses (the frequency and amplitude thereof being adjustable) to the seat carrier (16). According to the invention, the seat carrier (16) is supported to be tiltable laterally about its longitudinal axis (2) as well as forwards. The seat carrier (16) can also be swivelled about a pivot (6) forwards and upwards along a circular path, the seat carrier (16) remaining horizontal, and can be rotated about its vertical axis (4).
