This application relates to a treadmill. In one aspect, the treadmill includes a frame structure, a track part configured to rotate with respect to the frame structure, and a rotation unit disposed in the frame structure and rotatably supporting the track part. The track part may include a plurality of slats arranged in a rotation direction and a track belt disposed at both end portions of the plurality of slats and connecting the plurality of slats. The rotation unit may include first rotation members disposed in front and rear of the frame structure. At least one of the first rotation members includes a plurality of grooves arranged apart from each other on an outer circumferential surface of the at least one of the first rotation members in a circumferential direction, to have a surface shape different from an inner circumferential surface of the track belt.

A motor-less leg-powered curved treadmill produced that allows people to walk, jog, run, and sprint without making any adjustments to the treadmill other than shifting the user's center of gravity forward and backwards. A closed loop treadmill belt running between front and rear pulley rollers is formed with a low friction running surface of transverse wooden, plastic or rubber slats attached to each other in a resilient fashion, wherein each transverse slat has at least one continuous fin descending downward therefrom.

The invention relates to the field of treadmill technology, and more particularly to the low noise type direct drive type treadmill. It has solved the technical problems such as large output power loss and large noise. The low noise type direct-drive type treadmill comprises a running platform, an endless running belt is arranged on the running platform, a rotating roller is arranged at one end of the running platform and a tubular motor is arranged at the other end. Mentioned above rotary roller and tubular motor being arranged parallel to each other and provided with a running belt fixed to the running platform between the rotating roller and the tubular motor, mentioned above annular running belt being arranged between the rotating roller and the tubular motor and mentioned above annular running belt is located on the periphery of the running belt when the tubular motor is operable to drive mentioned above endless running belt. Compared with the prior art, the invention has the advantages that the noise is small and the running energy consumption is greatly reduced and the cost is low.

A computerized treadmill is provided. The treadmill may include a walking layer, a middle layer fully suspending the walking layer via a plurality of air suspension elements, and a foundation layer. The air suspension elements, such as bellows, may be pressurized by a computer-controlled compressor feeding a central air reservoir to which each bellows is connected via air hose. The air suspension elements may be dampened to control expansion. One or more alignment elements, such as double hinge structures, may be used to control lateral movement and reduce lateral load on the bellows.

A curved manual treadmill for the physical exercises of a user, comprising: a frame extending along a longitudinal direction; a first rotation shaft adapted to rotate around a respective first rotation axis transversal to the longitudinal direction of the frame; a second rotation shaft adapted to rotate around a respective second rotation axis transversal to the longitudinal direction of the frame; a physical exercise surface operatively connected to the first rotation shaft and to the second rotation shaft, so as to generate an endless closed physical exercise path, and a device for resisting the movement of the upper portion of the physical exercise surface operatively associated with at least either the first rotation shaft or the second rotation shaft.

The present invention relates to an exercise apparatus. The exercise apparatus includes a platform with an endless belt. The endless belt defines an exercising space above it. A restricting device has a retaining portion, a left restricting portion and a right restricting portion. The two restricting portions are elongated and flexible, such as straps. The left restricting portion is connected to a left end of the retaining portion from a left rear of the exercising space. The right restricting portion is connected to a right end of the retaining portion from a right rear of the exercising space. The restricting device maintains the retaining portion at an appropriate position to make the retaining portion naturally abut against a waist of the user for resisting forward movement of the user toward a front side of the exercising space and allowing the user to sprint or quick run on the platform.

Some embodiments of the present disclosure include a system for rotatably and horizontally suspending a running/walking surface over air without being supported by a deck and a treadmill including the same. The system may include a belt rotationally suspended between a pair of rails, the belt configured to support a user; a plurality of pairs of grommets spaced along a length of the belt proximate to an edge of the belt; a bracket attached to a corresponding pair of grommets by a cable, wherein the bracket and the pair of grommets are positioned in a triangular relationship; a transporter bolt extending from the bracket; and a roller rotatably attached to the transporter bolt, wherein the roller is configured to engage with the rail.

A motor-less leg-powered curved treadmill produced that allows people to walk, jog, run, and sprint without making any adjustments to the treadmill other than shifting the user's center of gravity forward and backwards. A closed loop treadmill belt running between front and rear pulley rollers is formed with a low friction running surface of transverse aluminum, wooden, plastic, rubber or carbon fiber slats attached to each other in a resilient fashion. An essential feature of treadmill is the concave shape of the upper portion of the belt running surface, the treadmill configurations ensure that this shape is maintained during actual use. These configurations prevent the concave upper running surface portion from being pulled taut into a flat shape between the front and rear pulley rollers. The slats of the treadmill each have an end view crossectional I-beam shape, for strength and stability of the slat positioned upon the treadmill belt.

A treadboard and a treadmill includes two first elastic strips of same structure arranged abreast with the lengths disposed along the moving direction of the belt of the treadmill and a plurality of solid support strips; the first elastic strips are arc structural, the center of the arc structure is higher than two ends of the arc structure; either end of each first elastic strip is once formed with buffer portion that is flexible along the length direction, so that the buffer portions buffer the arc structure of the first elastic strip after fixedly connected to the base of the treadmill; the solid support strips is of straight strip structure respectively connected vertically between the two first elastic strips, two ends of each solid support strip are respectively connected to the corresponding upper sides of the two first elastic strips.

A differential air pressure system has a pressure bag with windows and preferred folding configuration such that when the bag is folded no window is folded. The pressure bag is supported by a lift support that is proximal to a user control panel and adjacent to or nearly adjacent to the user who is coupled to the pressure bag. A treadmill base for use with differential air pressure equipment is provided. There are various improvements provided to adapt the operations of the DAP system via the use of separate pressure volume and non-pressure volume portions of the treadmill base. Various improvements to serviceability and repairs are provided by placement of components outside of the pressure volume portion or by providing one or more pressure volume access points.
