Description

MULTI-FUNCTION SPORTING EQUIPMENT

The present invention relates to a multifunctional exercising apparatus, and more particularly, to a multifunctional exercising apparatus that provides an elastic force to a pivotal center of an abdominal exercising apparatus.

Modern people who live in a modern society that is complicated and diversified are experiencing a phenomenon that the stress is accumulated due to the surrounding factors such as heavy work, smoke, noise, etc., and the mental and physically weakening phenomenon is observed.

In addition, as a temporary measure to relieve the mental and physical stress accumulated in this way, too much of the favorite foods such as alcohol and tobacco are brought in close proximity, which not only solves the stress but also adversely affects the body and mind.

However, it takes a lot of time and space to do other sports such as walking or jogging.

Therefore, it is necessary for the modern people to use various devices such as a gym or athletic facility to perform various exercises in the room as a way to maintain a healthy mind and physical body.

Especially, as the number of people who want to have sex pack abs and raise a hot body recently has been increasing, a lot of exercise equipment that can perform the exercise to tighten the abdominal muscles in the narrow room is coming out.

In general, there are athletic athletic apparatus (a sit-up athletic apparatus) that strengthens abdominal muscles. Such a sit-up exercise apparatus is a device for training the muscles of the body such as the abdominal muscles by repeatedly folding back and forth around the waist in a bent state of the knee after supporting the back of the plate-type backrest by supporting the foot on the cushion .

On the other hand, in the case of exercise equipment used for exercising the abdominal muscles in addition to the exercise equipment, a exercise device equipped with a holder capable of holding the ankle is used. In such a exercise device, , Abdominal muscles, obese people, elderly people, and children tend to reject it because of the difficulty in performing abdominal exercises. Abdominal athletic apparatuses known to the public can only perform abdominal exercises, and various stretching exercises and whole body exercises There are many problems such as inability.

In the conventional art, the abdominal exercising exercise device, which is disclosed in Korean Utility Model Registration No. 20-0302525, includes a frame supported by front and rear legs; A buttress support plate fixed on the upper surface of the frame; A pushing bar having one end fixed by a pivoting bracket protruding from a bottom of the buttock supporting plate and inclined at an opposite end to the backrest plate; An elastic restoring mechanism fixed to a bottom portion of the buttock supporting plate to elastically drive the pushing bar and having a spring along a support shaft inserted through the pushing bar and an elastic adjustment nut for adjusting the elasticity of the spring; And a foot fixture installed at the front of the frame to fix the foot; And a control unit.

In such a conventional art, there is a problem that a spring for providing a compressive elastic force is disposed at a lower portion of the backrest plate, and therefore, the spring is required to be increased in length to provide an elastic force.

In addition, since it is used only for the abdominal muscle training, the usability of the exercise machine is very limited. Therefore, in order to stretch, for example, other than abdominal muscles, or to train the waist or lower body, another exercise machine should be purchased and used .

In addition, since it is a exercise device that only strengthens the abdominal muscles, there is no exercise effect in other parts, and since it is a simple repetitive exercise, it does not induce an interest, so that the exercise can not be continued for a long time.

In addition, since the abdominal exercise training apparatus is not folded, there is a problem that it takes up a lot of space when stored in the room.
