Abstract
An abdomen exerciser includes a main frame and a support frame which is pivotally connected with the main frame. The main frame and the support frame can be placed on the ground stably. The main frame has an inclined section which is pivotally connected with a dual link rod to support a back rest and to link a seat platform. The seat platform is connected with a rotatable seat. The support frame is pivotally connected with a foot frame which is disposed in front of the support frame and confined by a resilient rope or a spring. When the user lies down and sits up, the back rest is returned to the original position by the seat platform and the dual link rod, without using the spring or the resilient rope. The foot frame can be used for leg exercise.
Description
- 1. Field of the Invention
- The present invention relates to an abdomen exerciser, and more particularly to an abdomen exerciser which can exercise the abdomen muscles, stretch the back and exercise the leg muscles.
- 2. Description of the Prior Art
- A conventional abdomen exerciser is used for sit-ups, which can exercise waist and abdomen muscles. However, it cannot help the motion to stretch the waist. After the user lies down and sits up, the back rest is returned to its original position by means of a spring for the user to exercise the abdomen muscles. The conventional abdomen exerciser has the following shortcomings.
- 1. The back rest of the abdomen exerciser is pulled upright by the spring. The additional spring increases the cost and is dangerous because it is exposed.
- 2. The foot frame at the front end of the abdomen exerciser is fixed, which cannot be used for leg exercise.
- 3. The height of the seat is in a fixed way. The effect to stretch the back is limited. The restore force of the spring assists the user in sit-ups, which influences the effect to exercise the abdomen muscles.
- Accordingly, the inventor of the present invention has devoted himself based on his many years of practical experiences to solve this problem.
- The primary object of the present invention is to provide an abdomen exerciser. The abdomen exerciser of the present invention comprises a main frame and a support frame which is pivotally connected with the main frame. The main frame and the support frame can be placed on the ground stably. The main frame has an inclined section which is pivotally connected with a dual link rod to support a back rest and to link a seat platform. The seat platform is connected with a rotatable seat. Both sides of a rear end of the seat platform are connected with a pair of grasp rods for the user to grasp thereon when sitting on the seat to swing his/her lower body. The support frame is pivotally connected with a foot frame which is disposed in front of the support frame and confined by a resilient rope. The main frame has a turning section which is pivotally connected with the support frame. The seat platform has a front end which is pivotally connected to the main frame through a first shaft. The seat platform comprises a transverse stop rod which is located under the seat platform to straddle on the main frame to keep the seat platform in a level state. The seat is connected to the seat platform through a rotation shaft so that the seat can be rotated freely. The seat platform has a rear end which is pivotally connected with the front ends of left and right pull rods through a second shaft. The rear ends of the left and right pull rods are pivotally connected to the lower end of a middle post of the back rest through a third shaft. The back rest is provided with a pivot seat close to the lower end thereof. The upper end of a support rod is pivotally connected to the pivot seat through a fourth shaft. The lower end of the support rod is pivotally connected to a fixing seat on the main frame through a fifth shaft. The upper ends of left and right driving rods are pivotally connected to the middle sections of the left and right pull rods through a sixth shaft. The lower ends of the left and right driving rods are pivotally connected to the front ends of left and right driven rods through a seventh shaft. The rear ends of left and right driven rods are pivotally connected to the inclined section of the main frame through an eighth shaft. The seventh shaft is located under the inclined section of the main frame and has a distance from the inclined section of the main frame. The user sits on the seat and leans against the back rest, with his/her feet to hold against a foot rod of the foot frame. When the user lies down, the middle post has the fourth shaft of the support rod as the pivot to move the left and right pull rods upward through the third shaft and the left and right driven rods are also moved upward. The seventh shaft is stopped by the inclined section of the main frame to raise the seat platform. In another word, the seat is to raise the hip of the user for the user to stretch his/her waist and back. When the user sits up and the back rest returns to the original position, the seat platform is lowered until the stop rod gets contact with the inclined section of the main frame so that the seat is moved to the level position. The left and right pull rods are pressed downward by the seat platform to link the left and right driving rods to pull the back rest back. By repeating the aforesaid action, the user can exercise the abdomen muscles without using the restore force of a spring or a resilient rope. The present invention can enhance the effect to stretch the back.
- Preferably, the support frame at the front end of the main frame comprises a first joint at a rear end thereof. The first joint is fitted on the front end of the main frame and connected by a pivot shaft inserting through the front end of the main frame. A lock bolt is vertically inserted in the first joint and the front end of the main frame to position the first joint and the front end of the main frame. When the lock bolt is loosened, the support frame can be bent or detached from the main frame. Through the pivot shaft, the main frame can be steadily connected in the first joint or bent for storage.
- Preferably, the support frame comprises a leg rod at an upper end thereof and a second joint at the front end of the leg rod. The foot frame is connected to the second joint through a positioning shaft inserting in the second joint and the upper end of the foot frame. The foot rod is transversely connected to the lower end of the foot frame. A first pulley is provided on the foot frame above the foot rod. A second pulley is provided on the support frame, corresponding in position to the first pulley. The resilient rope winds around the first pulley and the second pulley. One end of the resilient rope is fixed to a first positioning seat on the front side of the foot frame, and the other end of the resilient rope is fixed to a second positioning seat on the rear side of the support frame. The foot frame can be turned up and down with the positioning shaft of the second joint as a pivot, cooperating with the elastic rope, for lifting leg exercise.
- Preferably, the second joint of the support frame has a first through hole, and the foot frame has a second through hole corresponding to the first through hole. A pin is inserted into the first through hole and the second through hole to position the foot frame in place. When the pin is taken out, the foot frame can be turned up and down for lifting leg exercise.
- The present invention has the following advantages.
- 1. The abdomen exerciser of the present invention not only facilitates the exercise to raise the hip but also enhances the effect to stretch the user's back and to exercise the abdomen muscles.
- 2. When the user lies down and sits up, the back rest is returned to the original position by the seat platform and the dual link rod, without using the spring or the resilient rope. The abdomen exerciser of the present invention is cost-effective and has no risk of damaging the user.
- 3. The foot frame of the present invention can be used for leg exercise.
