An exerciser chair in accordance with the present invention comprises a main frame with a rail, a seat assembly slidably mounted on the rail of the main frame, a stop formed on the rail to limit sliding movement of the seat assembly. A front end of the main frame selectively combines with a bicycling device, footrest device or lifting device. The seat assembly has arms for gripping and further has a pivotal backrest to provide a back-extending movement. Thereby, the exerciser chair has various combinations and operational selections in use.

A seat assembly 30 rotatably mounted on the rail 18 of the main frame 10 and comprising a seat 31 and sliding mount 32. The sliding mount 32 is attached under the seat 31 and is a rectangular collar correspondingly and slidably engaged the rail 18. The sliding mount 32 has a front and rear ends respectively having multiple wheels 321. By driving the wheels 321, the sliding mount 32 enables to smoothly slide along the rail 18. An ear 323 is formed at a bottom of the sliding mount 32 and has a hook 324 thereon. At least one resilient element 20, spring with end hooks for example, engages the hook 171, 324 on the ears 17, 323 of the rail 18 and the sliding mount 32 to provide a training resistance force and a restitution force to the seat assembly 30 (as shown in
A backrest assembly 40 mounted on the seat assembly 30 and comprises a backrest 41, two arms 43 and two supporting tubes 42. Each supporting tube 42 is L-shaped and attached to a backside of the backrest 41. The two supporting tubes 42 are pivotally and respectively attached to two sides of the pivoting block 322 on the sliding mount 32 so that the supporting tubes 42 with the backrest 41 can be adjusted to different inclined angles. A resilient element 44, such as a resilient rope, has one end attached to a middle section of each supporting tube 42 and another end attached to the sliding mount 32 to provide the backrest 41 with the training resistance force and the restitution force. Moreover, the backside of the backrest 41 has a soft pad 411 operationally clamped between the backrest 41 and the wheel 321 when the backrest 41 leans against the seat assembly 30.
A foot-mounting assembly is attached to the front end of the main frame 10 and selectively modified into a bicycling device, a footrest device or an extending device.
The bicycling device 50 is attached at the front end of the main frame 10 and comprises a connecting rod 51, a wheel assembly 55, two cranks 52, two pedals 53 and a resistance-adjusting element 54. The connecting rod 51 is secured on the front end of the main frame 10 and has a free end. The wheel assembly 55 is mounted on the free end of the connecting rod 51 and covered by a shell that contains the resistance-adjusting elements 54 inside to control the exercising levels of bicycling device. The two cranks 52 are oppositely connected to the wheel assembly 55 to drive the wheel assembly 55. The two pedals 51 are attached to two distal ends on the two cranks 52 respectively for resting user's feet. Moreover, the wheel assembly 55 further has knob 541 thereon to control the resistance-adjusting element 54. Particularly, the resistance-adjusting element is a belt (now shown) attached to a periphery of the wheel assembly and selectively strangling the wheel assembly by the knob to provide different resistance. Because the bicycling device is a well-known structure in exercising equipments, redundant descriptions about the wheel assembly 55 and the resistance-adjusting element 54 are obviated here.

According to above description, the exerciser chair in the present invention has the following advantages:
1. The exerciser chair has various operational modes such as sliding, back-stretching, bicycling, foot-extending movements for exercise selection and can replace a lot of exercising equipments. Therefore, equipment cost is correspondingly reduced and indoor space is sufficiently saved.
2. The exerciser chair of the present invention has simple structure so that malfunction on elements is avoided. Moreover, the product price and maintain fee of the exerciser chair are low.
Although this invention has been described in its preferred form with a certain degree of particularity, it is understood that the present invention of the preferred form has been made only by way of example and that numerous changes in the details of construction and the combination and arrangement of parts any be resorted to without departing from the spirit and scope of the invention.
