The present disclosure discloses a vertical-column folding mechanism and a foldable treadmill. The vertical-column folding mechanism includes a first arm and a second arm; the first arm and the second arm are rotatably connected; a supporting member mounting cavity is arranged in the second arm; a retractable supporting member is arranged in the supporting member mounting cavity; two ends of the supporting member are respectively rotatably connected to the first arm and the second arm; and a rotatable connection point of the first arm and the second arm and rotatable connection points of the two ends of the supporting member are in a triangular distribution. The foldable treadmill includes the vertical-column folding mechanism.

An improved exercise machine has a stationary longitudinal monorail structure that extends between front and back end stationary exercise platforms, and an exercise platform mounted on a levitated carriage that is reciprocally movable along the monorail between the stationary platforms. Magnetic elements arranged on various opposing surfaces of the carriage and monorail generate magnetic forces that levitate and stabilize the carriage as it moves relative to the monorail thus substantially eliminating contact friction. Springs selectively attachable to the movable platform provide a resistance force for exercising. Pseudo-levitation and eddy brake elements on the carriage and monorail structure further stabilize the carriage and platform.

A weight plate includes a first section having an annular shape with a passage extending axially through the first section and configured to receive an elongated member therethrough, and a second section having an annular shape and positioned radially outward of the first section, where the second section includes first and second outer surfaces on opposite axial sides of the weight plate with an axial thickness defined between the first and second outer surfaces. The second section has a plurality of recesses each extending axially inward from the first and second outer surfaces at least partially through the axial thickness of the second section.

Disclosed is a weightlifting disc (1) which comprises a disc part (10) of elastomeric material, wherein the disc part (10) comprises an outer edge (11) and an inner edge (12), wherein the inner edge (12) is arranged close to a center (13) of the disc part (10) and the outer edge (11) of the disc part (10) is distal from the center (13) of the disc part (10). The weightlifting disc (1) further comprises at least one reinforcing device (20), arranged into the disc part (10) circumferentially around the center (13), between the outer edge (11) and the inner edge (12) of the disc part (10), wherein the reinforcing device (20) is arranged at a distance (a) from the inner edge (12) of the disc part (10) such as elastomeric material is arranged between the inner edge (12) of the disc part (10) and the reinforcing device (20).

A rehabilitation system using an artificially intelligent horseback-riding apparatus for hippotherapy, the system comprising: an artificially intelligent horseback-riding apparatus which is ridable; a smartphone which can communicate with a cloud server and has installed an application for controlling the operation state of the artificially intelligent horseback-riding apparatus and operating the horseback-riding apparatus; a diagnostic device which is for diagnosing the state of a patient by means of a brain wave signal of the patient; an operating unit which is for operating the artificially intelligent horseback-riding apparatus; and a cloud server which is for storing, in the smartphone, treatment program and data, necessary for a patient treatment, and for transmitting same.

The present invention relates to siding/covering materials (20) which are made of composite materials to be covered over metal posts (10) or horizontal bearing members (50) with angular or circular cross-section and which comprise reinforcing cells (25). Said composite material is composed of materials such as wood, plastics or a derivative thereof, pressed wood and paper, pressed plastics etc.

A fitness machine operable by a user. The fitness machine includes a base that extends in a length direction, a width direction, and a height direction that are perpendicular to each other. A mobile portion is configured to support the user during operation of the fitness machine. A resilient body is configured to provide a resistance against the mobile portion moving towards the base in the height direction. A frame is moveable in the length direction relative to the base to adjust the resistance provided by the resilient body. A fastener assembly moveably couples the frame to the base, where the fastener assembly is configured to expand in the width direction to prevent the frame from moving in the width direction relative to the base during operation of the fitness machine.

In one example in accordance with the present disclosure, a jump rope handle assembly is described. The jump rope handle assembly includes a handle having a longitudinal axis. A shaft assembly is disposed within the handle. The shaft assembly is to receive a jump rope section and is to rotate and slide within the handle. The shaft assembly includes a collet to retain the jump rope section. The jump rope handle assembly also includes a spring to compress between the shaft assembly and an interior impact surface of the handle.

A weight stack isolator comprises an impact damper having a rail void therein configured to receive a guide rail of a selectorized machine. The impact damper is shaped to at least partially surround a section of the guide rail when received in the rail void, to secure the weight stack isolator to the selectorized machine. The weight stack isolator may include a slit extending from its outer perimeter to the rail void or the rail void may extend to the outer perimeter, to removably receive the guide rail in the rail void. The weight stack isolator can be positioned under a weight stack of the selectorized machine to absorb or dampen noise and vibration.
