An apparatus 1 to aid walking, the apparatus 1 comprising a base unit 3, housing a motor; and further comprising first and second horizontally orientated foot supports 6,7, mounted for back and forth parallel motion relative to the base unit 3; the foot supports 6,7 each being operably connected to the motor; a foot support comprising a plurality of planar members 5, including a base plate 41, an intermediate plate 44 and a foot plate 45 having an upper surface to receive a user's foot, the intermediate plate 44 being pivotally linked at a first end to the base plate 41 and at a second end to the foot plate.

A stationary exercise bike has an exercise bike body assembly and a desk plate assembly. The desk plate assembly includes a desk plate and a fixing seat for the desk plate. The desk plate is in slide connection with the fixing seat for the desk plate. The fixing seat for the desk plate is connected with the stationary exercise bike body assembly through a lifting assembly. The fixing seat for the desk plate can be lifted up and down relatively to the stationary exercise bike body assembly due to the connection of the lifting assembly.

A stationary exercise device having variable footpaths is disclosed. The exercise device includes a frame, a pair of supporting members that have a first end to rotate about an axis and a second end to move along a reciprocating path, a pair of pedals joined to the supporting members, and a guider assembly for adjusting an incline angle of the reciprocating path.

A dynamic belt-tensioning apparatus for a treadmill includes a base having a first end and a second end spaced from the first end. A foot-striking platform is movably supported by the base so as to allow vertical movement of the platform during operation of the treadmill. A drive belt has a fixed circumference and is positioned above a top portion of the platform. A drive roller is pivotally mounted adjacent to the first end of the base and engages the drive belt. A tensioning roller is pivotally mounted to the base and is capable of a range of movement to provide substantially constant tension to the drive belt in response vertical movement of the platform.

The present disclosure relates, in one embodiment, to an unstable surface training apparatus. The apparatus may include a platform that is pivotally connected to a support member about the pivot axis. The apparatus may include at least one user handle that is adjustably connected to the platform. The platform may be freely pivotable about the pivot axis up to a maximum degree of rotation. Some embodiments of the exercise apparatus may include an base upon which the support member is connected. The base provides the exercise apparatus with increased stability. Other embodiments of the exercise apparatus may include a rotational restriction assembly disposed between the support member and the platform for limiting the maximum degree of rotation.

An exercise machine is for performing a striding exercise motion. The exercise machine has frame; first and second pedal members; first and second foot pads on the first and second pedal members, respectively, each of the first and second foot pads being configured to move in an elliptical path during the striding exercise motion; first and second rocker arms pivotally coupled to the frame; and first and second adjustment devices configured to actively adjust and set a position of the first and second pedal members relative to the first and second rocker arms, respectively, which thereby changes a shape of the elliptical path.

The invention relates to a device for posturography having a measuring platform, which comprises a standing surface for a test person having a base element on which the measuring platform is tiltably supported by means of a tilting apparatus, and having an air cushion means with which an air cushion bearing the base element is formed, wherein a damping member having a damping material is arranged between the measuring platform and the base element, by which damping member a tilting movement of the measuring platform is damped.

Disclosed is a moving cyclic machine which is implemented to perform an elliptical motion or interpolating curve motion independently from pedal rotation in a mechanical aspect so as to remedy boredom and improve a difficult exercise process of existing cycle exercise and to provide interest and motivation by increasing a level of a sense of immersion such that a user can continuously do lower body exercise and aerobic exercise for a long time everyday.

A dynamic belt-tensioning apparatus for a treadmill includes a base having a first end and a second end spaced from the first end. A foot-striking platform is movably supported by the base so as to allow vertical movement of the platform during operation of the treadmill. A drive belt has a fixed circumference and is positioned above a top portion of the platform. A drive roller is pivotally mounted adjacent to the first end of the base and engages the drive belt. A tensioning roller is pivotally mounted to the base and is capable of a range of movement to provide substantially constant tension to the drive belt in response vertical movement of the platform.

An exercise machine which provides a continuously variable exercise path for a user, based on the use of a first crank which rotates about a primary axis, and a second crank which is user-rotated about a second axis on the first crank and which is linked to a stationary cog so that the first and second cranks counter-rotate.
