EQUIPMENT FOR ABDOMINAL MUSCLES SPORTING [0002]

The present invention relates to an abdominal exercise apparatus, and more particularly, to an abdominal exercise apparatus capable of doubling the exercising effect of the abdominal muscles in spite of a small volume and a simple structure, and being able to exercise abdominal exercises easily and happily at any time, The present invention relates to an abdominal exercise apparatus capable of proceeding.

In modern people, abdominal muscles such as abdominal muscles and spinal muscles are weakened due to lack of exercise and excessive sedation, which causes chronic back pain, spinal diseases and abdominal obesity.

Therefore, interest in abdominal exercise is increasing recently. Dead lift and back extension are known as typical abdominal exercise methods for healing back pain and spinal diseases and abdominal obesity.

However, these exercises require a trainer's guidance. In other words, if the abdominal exercise is performed without the correct guidance of the trainer, the risk of injury may follow.

Thus, the majority of people prefer sit-ups as the simplest method of abdominal exercise. Sit-up is a typical abs-exercise method that can be carried out without a trainer, and the exercise is performed by overcoming the self-weight of the upper body using the abdominal muscles of the body in a state in which the feet are fixed.

On the other hand, although sit-up raising is effective for the abdominal muscle exercise, sit-up raising has a disadvantage in that it is difficult to carry out sit-ups, outdoors, or in the company, for example.

Recently, a variety of abdominal exercises have been developed to replace sit-ups, such as sit-ups, so that the abdominal exercises can be intensively performed.

However, the conventional abdominal exercise machines currently available on the market have a relatively complicated structure or have a large volume, so that manufacturing and purchasing costs are inevitably increased. In addition, the abdominal exercise machines occupy a lot of space and are not easy to handle or handle, It is troublesome and difficult to use, so there is a need for a new concept of abdominal exercise apparatus which is not known.

Referring to these drawings, the abdominal muscle exercising apparatus 100 according to the present embodiment can double the exercise effect of the abdominal muscles in spite of the small volume and simple structure, and can easily and at any time easily and happily, Exercise, and further contribute to resolving chronic back and spine diseases and abdominal obesity.

The abdominal exercise device 100 according to the present embodiment for providing such an effect is provided with a waist support unit 110, an arc type rail unit 120, a connection block 170, a sliding movement unit 130, A first elastic connecting unit 140, a second elastic connecting unit 150, and a grip unit 160. [

The waist supporting unit 110 is a part in which a user places a waist for supporting a user to perform exercise. And the abdominal muscle movement can be performed with the waist support unit 110 as a support shaft.

The waist supporting unit 110 is applicable as a plastic ring or a belt. That is, the waist supporting unit 110 may be manufactured in the form of a plastic ring like a hula hoop, or the waist supporting unit 110 may be applied in the form of a waist belt used in a gym.

 In the case of this embodiment, the waist supporting unit 110 is applied by an electronic plastic ring, and the scope of the right of the present invention is not limited to these matters.

The arc-type rail unit 120 is an arc-shaped injection structure connected to the waist supporting unit 110. An arc-shaped rail 121 is formed on the arc-shaped rail unit 120.

The connecting block 170 serves to connect the waist supporting unit 110 and the arm type rail unit 120.

The connecting block 170 may be made of a shock-absorbable rubber material so that the waist supporting unit 110 is not impacted during abdominal muscle exercise.

The sliding unit 130 is coupled to the rail 121 of the arc-type rail unit 120 and is slidably moved along the locus of the rail 121. I.e., from the initial (P) position of FIG. 3 to the one side P1 of FIG. 4 or the other side P2 of FIG.

Components such as rollers and bearings may be mounted on the sliding unit 130 so that the sliding unit 130 can be slid along the locus of the rail 121, .

The first elastic connection unit 140 includes a first elastic string 141 elastically connecting one side of the sliding movement unit 130 and one side of the waist support unit 110, Has a second elastic string 151 for elastically connecting the other side of the sliding unit 130 and the other side of the waist supporting unit 110. [

The first elastic ribs 141 and the second elastic ribs 151 may be fixedly coupled to one side and the other side of the sliding unit 130 by means of hooks or the like.

In this embodiment, the first elastic connection unit 140 and the second elastic connection unit 150 have the same structure.

2, each of the first elastic connection unit 140 and the second elastic connection unit 150 includes a first elastic string 141 and a second elastic string 151, (143), and an annular hook (144) connected to the unit coupling aperture (143). Although the detailed structure of the second elastic connection unit 150 is not shown, the detailed structure of the second elastic connection unit 150 is considered to be the same as the detailed structure of the first elastic connection unit 140, do.

In order to engage the annular hook 144 of the first and second elastic connecting units 140 and 150 having such a structure, a plurality of annular hooks 144 are detachably coupled to the outer wall of the waist supporting unit 110 A hooking member 115 is provided.

The hooking member 115 may include a hooking neck 115a and a hooking ball 115b formed at an end of the hooking neck 115a. The annular hook 144 of the first and second elastic connection units 140 and 150 can be caught by the boundary line between the engagement neck 115a and the engagement ball 115b.

6, when the annular hooks 144 of the first and second elastic connection units 140 and 150 are moved to the far side of the plurality of hooking members 115, And the elasticity of the second elastic strands 151 can be strengthened. Therefore, the force applied to the abdominal muscles can be fine, which is advantageous for the exercise of the skilled person.

 As a result, by selectively engaging the annular hook 144 of the first and second elastic connection units 140 and 150 with the hooking members 115, the elasticity of the first elastic string 141 and the second elastic string 151 So that it is possible to control the degree.
