Description
- 1. Field of the Invention
- The present invention relates to a stationary exercise device, and more particularly to an elliptical or stationary exercise device including a braking or resistive device for braking or resisting the elliptical movement of the exercise device, and for suitably controlling the elliptical movement or the actuation or the working or the operation of the elliptical exercise device.
- 2. Description of the Prior Art
- Typical exercise devices, such as stepping exercisers comprise a pair of handles pivotally attached to an upwardly extending frame member of a base support device, and a pair of foot supports pivotally coupled to the handles and arranged for allowing the foot supports to be stepped or moved up and down relative to the base support device.
- For example, U.S. Pat. No. 7,485,072 to Chuang et al., U.S. Pat. No. 7,556,591 to Chuang et al., U.S. Pat. No. 7,608,018 to Chuang et al., and U.S. Pat. No. 7,611,446 to Chuang et al. disclose several of the typical elliptical or stepping or stationary exercise devices each comprising a pair of handles pivotally attached to an upwardly extending frame member of a base support device, and a pair of foot supports pivotally coupled to the upwardly extending frame member and the base support device and also coupled to the handles for allowing the foot supports to be stepped or moved up and down relative to the base support device by the user.
- However, the movement of the foot supports relative to the upwardly extending frame member and the base support device may not be resisted or braked, i.e., the typical elliptical or stepping or stationary exercise devices have no brake or resistive devices provided for braking or resisting or retarding the movement of the foot supports relative to the upwardly extending frame member and the base support device such that the movement of the foot supports may not be suitably controlled.
- The present invention has arisen to mitigate and/or obviate the afore-described disadvantages of the conventional elliptical exercise devices.
- The primary objective of the present invention is to provide a stationary or elliptical exercise device including a braking or resistive device for braking or resisting the elliptical movement of the exercise device, and for suitably controlling the elliptical movement or the actuation or the working or the operation of the elliptical exercise device.
- The other objective of the present invention is to provide a stationary exercise device including an adjustable arrangement for suitably adjusting the braking force or resistance applied to the elliptical exercise device.
- In accordance with one aspect of the invention, there is provided a stationary or elliptical exercise device comprising a base, a pair of foot supports, a support device for supporting the foot supports above the base and for allowing the foot supports to move cyclically and elliptically relative to the base, and a resist device coupled between the foot support and the support device for applying a resistive force to the foot support and for braking an elliptical movement of the foot support relative to the support device, wherein the resist device includes a first member and a second member slidably coupled together and moveable linearly relative to each other for applying a frictional and resistive force between the first and the second members and for resisting a linear movement between the first and the second members, and thus for resisting the elliptical movement of the foot support relative to the support device.
- The first member includes a cylindrical structure having a bore formed therein for slidably receiving and engaging with the second member. The resist device includes a brake element engaged into the bore of the first member and contacted or engaged with the second member for applying a frictional and resistive force between the first and the second members.
- The first member includes two casings, and the brake element includes two shoe segments attached to the casings respectively and contacted or engaged with the second member for applying the frictional and resistive force onto the second member and thus for resisting the linear movement between the first and the second members.
- The resist device includes at least one spring member engaged with the casings for applying a spring biasing force onto the casings and for biasing the shoe segments of the brake element toward each other and to engage with the second member and to apply the frictional force onto the second member.
