BACKGROUND OF THE INVENTION This invention relates to an abdominal platform.

[0002]

2. Description of the Related Art The abdominal muscle table is a muscle strength training machine configured to improve the abdominal muscle strength. However, in the conventional abdominal muscle table, the buttocks receiving sheet stands vertically at one end of the bench seat where the exerciser lies supine. In addition, the leg receiving pad and the ankle receiving pad are fixed at a constant height from the buttocks receiving sheet, and the foot table is hooked and fixed to the ankle receiving pad, and the undulating motion is repeatedly performed on the bench seat. Is.

[0003]

However, according to the conventional abdominal muscle stand, since the leg receiving pad and the ankle receiving pad are fixed at fixed positions, the back of the upper limb may be different depending on the height of the exerciser. However, since it does not adhere to the buttocks receiving sheet, and therefore the ankle is loaded, the load on the abdominal muscles is reduced and effective training cannot be performed.

Also, when raising or lowering the leg to or from the leg receiving pad, an unnatural state may occur, which may cause back pain.

Therefore, an object of the present invention is to provide an abdominal muscle platform that enables effective abdominal muscle training.

[0006]

This invention is a bench seat
A buttock receiving sheet is erected vertically at one end of the
The leg receiving pad and the foot are located above the buttocks receiving sheet.
A neck support pad is provided, and the foot surface is pulled on the ankle support pad.
It is fixed by hanging it and repeatedly undulating on the bench seat.
In the abdominal muscle stand, the buttocks receiving sheet was fixed.
The inner tube can be axially moved to the outer tube and can be locked at the desired height
Is installed vertically, and the leg support is attached to the upper end of the inner pipe.
Fix the pad and attach the arm diagonally upward to the inner tube.
The ankle pad is connected to the upper end of the arm.
While fixing the ankle support pad and the leg support pad
Vertically install a safety grip on the arm between
Characterized in that it comprises Te.

[0007]

[Operation] By extending and locking the inner tube from the outer tube
The height of the ankle pad can be adjusted. Then, when the ankle is hung on the ankle pad or the leg is removed from the ankle pad, the safety grip is sandwiched between the two legs, which serves as a guide for preventing an unnatural state of the body.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described with reference to the drawings. 1 is a front view and FIG. 2 is a side view, in which 1 is a bench seat, 2 is a buttocks receiving seat, 3 is a leg receiving pad, 4 is a safety grip formed integrally with the leg receiving pad 3, 5 Is an ankle receiving pad integrally formed with the leg receiving pad 3.

The height of the leg receiving pad 3 is adjustable. That is, in the center of the back of the buttocks receiving sheet 2,
The outer pipe 7 connected to the frame 6 of the bench seat 1 is vertically erected, the inner pipe 8 is axially movably inserted into the outer pipe 7, and the leg receiving pad 3 is attached to the upper end of the inner pipe 8. It is fixed. As shown in FIG. 3, a block 9 is internally fitted and fixed to the lower end of the inner pipe 8, and a pole 10 penetrating the center of the block 9 is erected on the frame 6 at the center of the outer pipe 7. It is fixed. A stopper 11 is provided at the upper end of the pole 10 for preventing the pole 10 from coming off, and a compressed coil spring 12 is mounted between the block 9 and the frame 6.

Further, an arm 13 which is orthogonal to the upper end of the inner pipe 8 and projects obliquely upward is provided, and a central portion of a shaft 14 is connected and fixed to the upper end of the arm 13 and the arm 13 is fixed to the shaft 14. Ankle pad 5 is attached to each of the left and right sides centering around. A safety grip 4 is vertically erected and fixed on the base of the arm 13 in front of the ankle pad 5.

As shown in FIG. 3, the outer tube 7 and the pole 8 are locked by fixing the cylindrical body 15 orthogonally to the upper end of the outer tube 7 and screwing the threaded portion 16 on the inner periphery of the cylindrical body 15. The inner cylinder 17 provided and screwed into the inner cylinder 17 is inserted, and the inner cylinder 17 and the lock pin 1 are inserted.
A spring 19 is mounted between the springs 8 to urge the lock pin 18 through a washer 21 that presses against the inner pipe 8.
Grip 20 attached to the outer end of the lock pin 18
And the inner end of the lock pin 18 is engaged with holes 22 formed in the pole 8 at regular intervals in the height direction. When the grip 20 is pulled outward, the inner tube 8 is automatically raised by the force of the compressed coil spring 12.

To explain the operation of the above-mentioned embodiment, as shown in FIG. 4, the training person 23 lies on the bench seat 1 and puts the buttocks on the buttocks receiving sheet 2 so that both upper limbs are vertical and the grip 20 By pulling outward to adjust the height of the leg receiving pad 3 according to the height (length) of the upper limb, and sandwiching the safety grip 4 between the lower limb and the leg receiving pad 3
And place them on the ankle pad 5, and fix them by hooking them on the ankle pad 5. In this state, by placing both hands on the head and undulating the body around the buttocks, the abdominal muscles are trained.

[0013]

According to the present invention described above, since the height of the ankle pad can be adjusted, the pad can be used according to the height of the exerciser, so that proper and effective abdominal exercises can be performed. Also, with ankle pad and leg pad
Since the safety grip was erected vertically on the arm between the two, when putting the leg on the leg receiving pad or lowering it,
Hold the lower limb with the safety grip in between
By guiding to the pad, it is easy to take the abdominal posture,
At the end, you can support your body safely,
As a result, it is possible to prevent the risk of an unnatural state resulting in injury such as low back pain.
