Adjusting exercise device

Adjusting exercise device description/claims

1. Field of the Invention

The present invention relates to an adjusting exercise device, and more particularly to an elliptical exercise device including an arrangement for allowing the exercise device to have changeable or adjustable or different moving strokes.

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. 5,290,211 to Stearns discloses one of the typical exercise devices also 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 handles, and a pair of force resisting device pivotally coupling the foot supports to the upwardly extending frame member for allowing the foot supports to be stepped or moved up and down relative to the base support device.

However, normally, the middle portion of the foot supports is pivotally coupled to the upwardly extending frame member such that the middle portion of the foot supports is pivoted relative to the base support device but may not be moved cyclically or in reciprocating relative to the base support device, and such that the moving stroke of the typical exercise devices may not be suitably increased. In addition, the moving stroke of the typical exercise devices may not be changed or adjusted.

U.S. Pat. No. 5,499,956 to Habing et al. discloses a typical articulated lower body exercise device comprising a pair of foot supports pivotally coupled to the upwardly extending frame member of a base support device with a pair of vertical linkage arms, and a device for swinging the vertical linkage arms and the foot supports relative to the upwardly extending frame member of the base support device for allowing the foot supports to be stepped or moved elliptically relative to the base support device.

However, the middle portion of the foot supports is only pivoted relative to the base support device but may not be moved cyclically or in reciprocating relative to the base support device, and such that the moving stroke of the typical exercise devices may not be suitably increased. In addition, the moving stroke of the typical exercise devices may not be changed or adjusted.

U.S. Pat. No. 5,577,985 to Miller discloses a typical stationary exercise device comprising a pair of guide links or handles pivotally attached to an upright support, and a pair of foot supports each pivotally coupled to the handles, and a pair of cranks pivotally coupled to the handles and the foot supports with an intermediate link and a control link, for swinging the handles and the foot supports relative to the base support device and for allowing the foot supports to be stepped or moved elliptically relative to the base support device.

However, the middle portion of the foot supports is only pivotally coupled to the handles, and may not be moved cyclically or in reciprocating relative to the base support device such that the moving stroke of the typical exercise devices may not be suitably increased or adjusted. In addition, the moving stroke of the typical exercise devices may not be changed or adjusted.

U.S. Pat. No. 5,595,553 to Rodgers, Jr. discloses another typical stationary exercise device also comprising a pair of handles pivotally attached to an upright support, and a pair of foot supports each pivotally coupled to the handles, and a pair of cranks pivotally coupled to the foot supports with a reciprocating member for swinging the handles and the foot supports relative to the base support device and for allowing the foot supports to be stepped or moved elliptically relative to the base support device.

However, similarly, the foot supports is only pivotally coupled to the handles, and may not be moved cyclically or in reciprocating relative to the base support device such that the moving stroke of the typical exercise devices may not be suitably increased or adjusted.

U.S. Pat. No. 5,769,760 to Lin et al. discloses a further typical stationary exercise device comprising a pair of foot supports including a front portion pivotally coupled to an upright support, and a pair of handles also pivotally attached to the upright support, and a pair of cranks pivotally coupled to the handles for swinging the handles and the foot supports relative to the base support device and for allowing the foot supports to be stepped or moved elliptically relative to the base support device.

However, the handles are located closer to the users, and are pivotally coupled to the upright support and may also be moved cyclically relative to the upright support of the base support device such that the handles will also be moved cyclically relative to the upright support and such that the handles may not be suitably or easily grasped and handled by the users. In addition, the moving stroke of the typical exercise devices may not be changed or adjusted.

U.S. Pat. No. 6,022,296 to Yu discloses a further typical stepping exercise device comprising a pair of handles pivotally coupled to an upright support with a pair of cranks, and a pair of foot supports including a middle portion pivotally attached to the base support and including a front portion pivotally coupled to the handles.

However, the foot supports are only coupled to the upright support or the base support such that the foot supports may only be stepped or moved up and down relative to the base support device, but may not be stepped or moved elliptically relative to the upright support of the base support device. In addition, the moving stroke of the typical exercise devices may not be changed or adjusted.

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 an adjusting exercise device including an arrangement for allowing the exercise device to be adjusted to different moving strokes.

In accordance with one aspect of the invention, there is provided an adjusting exercise device comprising a base including an upright support extended upwardly from the base, a spindle disposed on the upright support, two cranks rotatably coupled to the rear portion of the upright support with a shaft which is spaced away from the spindle, the cranks each including a pivot rod attached to the crank and spaced away from the shaft, two handles including a middle portion attached to the spindle for allowing the handles to be pivotally coupled to the front portion of the upright support with the spindle and for allowing the handles to be pivoted and swung relative to the upright support of the base, the handles each including a hand grip provided on an upper portion for being grasped or held by a user and each including a lower portion, two foot supports each including a front portion pivotally coupled to the lower portion of the handles, and each including a foot pedal disposed on a rear portion for supporting the user's feet, and each including a middle portion pivotally coupled to the pivot rod of the cranks with a link for allowing the middle portions of the foot supports to be moved cyclically relative to the upright support by the cranks, two levers each including a first end pivotally coupled to the pivot rod of the crank, and each including a second end adjustably coupled to the middle portion of the handle and spaced away from the spindle for forming a changeable polygonal coupling structure together with the handles and the foot supports and the links, and for allowing the foot pedals of the foot supports to be moved with changeable and elliptical moving stroke relative to the upright support of the base, and a moving device for moving the second end of the lever along the middle portion of the handle and toward and away from the spindle for adjusting a moving stroke of the foot pedals of the foot supports.

The second ends of the levers are each coupled to the middle portions of the handles respectively with a securing device. The handles each include a channel formed in the middle portion of the handle for slidably engaging with the securing device. The levers each include a bracket provided on the second end of the lever for supporting the securing device.

The moving device includes a threaded member rotatably supported in the middle portion of the handle for engaging with the securing device and for moving the securing device along the middle portion of the handle when the threaded member is rotated relative to the middle portion of the handle.
