Background of the Invention
The invention relates to an exercise device. More particularly, the invention relates to an exercise device for various exercising purposes.
Most conventional exercise devices have simple training functions and purposes. One type of exercise device cannot be converted to the other type of exercise device. If an exercise device provides many different training functions, the exercise device should have complex structure. Thus the complex exercise device may be very expensive. It is very difficult to familiarize the operation of the complex exercise.
Summary of the Invention
An object of the invention is to provide an exercise device for various exercising purposes.
Accordingly, an exercise device comprises a first handle, a second handle, a hollow outer pipe, a hollow inner pipe, an elastic ring, and a first, second and third hollow elastic pipes. A curved plate is positioned on a rear middle portion of the first handle. A first, second and third recesses are formed on an upper middle portion of the first handle. A hollow stud is positioned on a center of the first handle. A round through hole is formed on the hollow stud. A first and second foam casings enclose a right and left portions of the first handle, respectively. A hollow box is disposed on a center of the second handle. A first, second and third grooves are formed on an upper portion of the hollow box. A first and second foam housings enclose a right and left portions of the second handle, respectively. A circular through hole is formed on a rear end of the hollow inner pipe. A first, second and third notches are formed on a front end of the hollow inner pipe. Each of the first, second and third hollow elastic pipes has a first and second balls disposed at a front and rear ends of each of the first, second and third hollow elastic pipes, respectively. A rear end of the elastic ring is inserted in the hollow stud. The hollow stud is inserted in the rear end of the hollow outer pipe. A first fastener positions the hollow stud in the hollow outer pipe and the elastic ring in the hollow stud. A front end of the elastic ring is inserted in the hollow inner pipe. The hollow inner pipe is inserted in the front end of the hollow outer pipe. A second fastener positions the hollow inner pipe in the hollow outer pipe and the elastic ring in the hollow inner pipe. Each of the first, second and third hollow elastic pipes is inserted in the corresponding recess and the corresponding groove, respectively.

Detailed Description of the Invention
Referring to FIGS. 1 and 2, an exercise device comprises a first handle 1, a second handle 2, a hollow outer pipe 3, a hollow inner pipe 4, an elastic ring 5, and a first, second and third hollow elastic pipes 6, 6' and 6". A curved plate 13 is positioned on a rear middle portion of the first handle 1 to abut the belly of the user. A first, second and third recesses 12, 12' and 12" are formed on an upper middle portion of the first handle 1. A hollow stud 14 is positioned on a center of the first handle 1. A round through hole 141 is formed on the hollow stud 14. A first and second foam casings 11 and 11' enclose a right and left portions of the first handle 1, respectively. A hollow box 22 is disposed on a center of the second handle 2. A first, second and third grooves 23, 23' and 23" are formed on an upper portion of the hollow box 22. A first and second foam housings 21 and 21' enclose a right and left portions of the second handle 2, respectively. A circular through hole 42 is formed on a rear end of the hollow inner pipe 4. A first, second and third notches 41, 41' and 41" are formed on a front end of the hollow inner pipe 4. Each of the first, second and third hollow elastic pipes 6, 6' and 6" has a first and second balls 61 disposed at a front and rear ends of each of the first, second and third hollow elastic pipes 6, 6' and 6", respectively. A rear end of the elastic ring 5 is inserted in the hollow stud 14. The hollow stud 14 is inserted in the rear end of the hollow outer pipe 3. A first pin 1411 positions the hollow stud 14 in the hollow outer pipe 3 and the elastic ring 5 in the hollow stud 14. A front end of the elastic ring 5 is inserted in the hollow inner pipe 4. The hollow inner pipe 4 is inserted in the front end of the hollow outer pipe 3. A second pin 421 positions the hollow inner pipe 4 in the hollow inner outer pipe 3 and the elastic ring 5 in the hollow inner pipe 4. Each of the first, second and third hollow elastic pipes 6, 6' and 6" can be inserted in the corresponding recess 12, 12' or 12" and the groove 23, 23' or 23", respectively. If the user has a strong force, each elastic pipe 6, 6' or 6" can be inserted in the corresponding groove 23, 23' or 23" and the notch 41, 41' or 41", respectively (as shown in FIGS. 3 and 4). The belly A of the user abuts the curved plate 13. Two hands of the user grip the first and second foam housings 21 and 21' and press the second handle 2 toward the belly A.
The feet of the user can touch the first and second foam casings 11 and 11', and the knees of the user can lift the second handle 2 upward.
The invention is not limited to the above embodiment but various modification thereof may be made. Further, various changes in form and detail may be made without departing from the scope of the invention.
