Abstract

An exerciser includes a board, a frame, a swing rod, an upper foot rest, a lower foot rest and a resilient rope. An upper end of the swing rod is articulated to an upper end of the vertical support and a lower end of the swing rod is fixed to a central portion of the lower foot rest. The resilient rope is connected between the swing rod and the vertical support. The board is fixed on the lengthwise beam of the frame. The lengthwise beam and the vertical support of the present invention form a triangular support. The board installed on the lengthwise beam is arranged obliquely. When the pin is inserted in the pin holes of the upper portion of the vertical support and the upper end of the swing rod, the swing rod won'"'"'t swing relative to the vertical support of the frame for doing sit-ups. When the pin is pulled out from the pin holes of the upper portion of the vertical support and the upper end of the swing rod, the swing rod will swing relative to the vertical support of the frame. The resilient rope provides a damping force for doing exercise to get stronger leg muscles. The present invention has a simple structure and multiple functions.

Claims

1. An exerciser, comprising a board, a frame, a swing rod, an upper foot rest, a lower foot rest and a resilient rope, the frame comprises a lengthwise beam, a vertical support, a front bottom bracket and a rear bottom bracket, a front end of the lengthwise beam being perpendicularly fixed to a central portion of the vertical support and a rear end of the lengthwise beam being perpendicularly fixed to a central portion of the rear bottom bracket, an upper end of the vertical support being fixed to a central portion of the upper foot rest and a lower end of the vertical support being fixed to a central portion of the front bottom bracket, the lengthwise beam and the vertical support forming a triangular support, an upper end of the swing rod being articulated to an upper end of the vertical support and a lower end of the swing rod being fixed to a central portion of the lower foot rest, the resilient rope being connected between the swing rod and the vertical support, the board being fixed on the lengthwise beam of the frame.

2. The exerciser as claimed in claim 1, wherein an inner end of the resilient rope is fixed to a lower portion of the vertical support, a central portion of the resilient rope winds through a first pulley on an upper portion of the vertical support, a second pulley on the lower portion of the vertical support and a third pulley on the lower end of the swing rod, and an outer end of the resilient rope is connected to a central portion of the swing rod.

3. The exerciser as claimed in claim 1, wherein the swing rod has a plurality of slots thereon, the resilient rope has a hook at an outer end thereof, and the hook is connected to one of the slots of the swing rod.

4. The exerciser as claimed in claim 1, wherein the upper portion of the vertical support has a pin hole for insertion of a pin.

5. The exerciser as claimed in claim 1, wherein the upper end of the swing rod has a pin hole for insertion of a pin.

6. The exerciser as claimed in claim 1, wherein the frame further comprises an armrest pipe and the armrest pipe is transversely connected to the lengthwise beam.
