A lifting and folding mechanism for treadmill includes a base, a platform, a lifting mechanism, and a linkage mechanism. An armrest rack and a control panel are assembled at the base. A front end of the platform is pivotally assembled with the armrest rack. The lifting mechanism includes a supporting rack and a driving device. One end of the supporting rack is pivotally assembled with the platform, and the driving device is connected between the supporting rack and the platform for driving the supporting rack abutting against the ground, so that the platform is lifted and the slope of the platform is changed. The linkage mechanism is connected to the base and the platform. The linkage mechanism is in a connection state or a disconnection state. In the connection state, the base is connected with the platform, and the base is lifted upward with the lifting of the platform.

A treadmill may include a lock mechanism operative to selectively lock a deck assembly in one or more positions relative to a base frame. The lock mechanism may include an engagement member that locks the deck assembly in an operating position while allowing incline adjustment of the deck assembly relative to the frame during use of the treadmill.

A treadmill may include a lift assistance mechanism operative to assist movement of a deck assembly between one or more positions relative to a base frame. A portion of the lift assistance mechanism may translate along a length dimension of the treadmill when inclining the deck assembly. The lift assistance mechanism may assist a user in moving the deck assembly into a storage position and may also assist a deck assembly lift motor in inclining the deck assembly.

Person support apparatuses having exercise features are disclosed herein. In various embodiments, a person support apparatus includes a support surface, a footboard, a sensor, and a passive resistance mechanism. The support surface has a foot end and a head end, and the footboard is located near the foot end of the support surface, extending above the support surface. The footboard may include a pressure surface positioned to receive a pressing force. The footboard is freely slidable from an extended position to a retracted position with respect to the foot end of the support surface. The sensor provides a signal indicative of a magnitude of the pressing force incident on the pressure surface of the footboard. The passive resistance mechanism is coupled to the footboard, and resists a motion of the footboard to the extended position.

A foldable treadmill includes a treadbase having two short sides and two long sides, a base frame extended in the extending direction of the short sides of the treadbase and supported on a supporting surface, a linkage unit coupled between the treadbase and the base frame, and a retractable unit including a pivot-connection portion pivotally connected to the base frame and a retractable member interlocking with the linkage unit and movable relative to the pivot-connection portion between a retracted position where the long sides of the treadbase are disposed in proximity to the supporting surface and an extended position where the long sides of said treadbase are disposed far from the supporting surface and the position of the linkage unit is shifted with the retractable member to reduce the clearance between the linkage unit and the treadbase to minimize space occupation.

A retractable wall mounted exercise rack system for providing an exercise rack that may be easily and compactly stored when not in use. The retractable wall mounted exercise rack system generally includes one or more brackets attached to a wall, a pair of support members, and a plurality of arms pivotally extending from the brackets and pivotally connecting to the support members. One or more actuators are connected between the brackets and the arms to assist in lifting the structure into a compact retracted position for storage.

The present invention concerns a gymnastic machine of the type having a sliding belt comprising a base structure, having a frame, on which a closed circuit sliding belt is installed for gymnastic exercises, a supporting structure rotatably coupled with said base structure, characterized in that said gymnastic machine comprises a closing and moving group, comprising a trolley, rotatably coupled with said frame of said base structure, capable to assume a first position, corresponding to the opening position of said gymnastic machine, wherein said trolley is substantially parallel to said base structure, and a second position, corresponding to the closing position of said gymnastic machine, wherein said trolley is rotated with respect to said base structure, so as to lift and rotate it with respect to said supporting structure, arranging close to it; and actuator means, capable to allow the moving of said trolley from said first position to said second position and vice versa.

An exercise apparatus includes a frame with at least 3 vertical legs and transverse cross braces connecting the legs. The frame also has a horizontal cross-section of at least 3 sides. Horizontal platforms are coupled to a first side of the frame and transverse to a first pair of the vertical legs. The horizontal platforms have a stepped configuration such that an upper platform is recessed compared to a lower platform. Horizontal bars are coupled to a second side of the frame and transverse to a second pair of the vertical legs. The horizontal bars have a stepped configuration such that an upper bar is recessed compared to a lower bar. The surface area of each of the horizontal platforms is at least 3 times greater than the surface area of each of the horizontal bars.

A lifting and folding mechanism for treadmill includes a base, a platform, a lifting mechanism, and a linkage mechanism. An armrest rack and a control panel are assembled at the base. A front end of the platform is pivotally assembled with the armrest rack. The lifting mechanism includes a supporting rack and a driving device. One end of the supporting rack is pivotally assembled with the platform, and the driving device is connected between the supporting rack and the platform for driving the supporting rack abutting against the ground, so that the platform is lifted and the slope of the platform is changed. The linkage mechanism is connected to the base and the platform. The linkage mechanism is in a connection state or a disconnection state. In the connection state, the base is connected with the platform, and the base is lifted upward with the lifting of the platform.
