Abstract

PROBLEM TO BE SOLVED: To provide a lower body expander mainly used for exercise and correction of the lower body, which is easy to house and carry and easily usable by any one at home, and can simultaneously attain the prevention of low back pain, the sufficient traction and correction of the lumber part, the muscular reinforcement of the leg and abdominal parts, and the finger pressure of soles by generating a composite force of a lateral force necessary for holding the lumber part and a vertical force necessary for drawing the lumber part by one operation. SOLUTION: This expander comprises a lumber band 1 having corresponding fasteners 2 and 2 of Velcro (R) (hook-and-loop) fasteners and a sole plate 6 having both foot insert parts 3 and 3. A band-like elastic cord 7 is inserted in a woven shape around substantially the latter half part of the band 1, and the elastic cord 7 comprises both extended ends 7a and 7a vertically connected to the extension middle parts thereof through connecting tools 8 each formed of a connecting ring 9 and a hook 10, and the ends 7a and 7a are connected to the side parts 6a and 6a of the sole plate 6 so as to be capable of adjusting the elasticity.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lower body expander which can be easily used by individuals at home and the like, and which is capable of simultaneously performing traction correction of the lumbar spine and preventing muscles in the legs and abdomen at the same time to prevent back pain.

[0002]

2. Description of the Related Art Household exercise aids such as hanging health devices, walkers, rolling devices, and cyclists, and health devices are commercially available. Apart from the case where a gym is provided, I hate it because it has become a hindrance when not in use due to recent housing conditions and is too expensive in terms of price. Of course, it doesn't fit into a cell phone. In addition, you can see the scene that you are tired and left alone if you continue to use it for a while. The same can be said for health equipment for preventing low back diseases such as tight back. No one has been able to simultaneously perform traction stretching of the lumbar region and muscle strengthening of the legs and abdomen, which is necessary for prevention, so far.

On the other hand, registered utility model No. 20818
No., Jikkai 55-72971, Jikkai 57-12316.
As shown in Fig. 7, a device for training the waist and legs by tightening the belt around the waist has been proposed. In these, the waist belt is just a fixed belt, and the movement of the legs is the main body. . When the legs are exercised, only the downward force (the force of slipping) is usually added to the waist. That is, a sufficient traction effect on the lumbar region cannot be obtained.

[0004]

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above-mentioned conventional circumstances, and is mainly intended to simultaneously perform traction and correction of the lumbar spine and muscle strengthening of the abdomen and lower limbs for storage and It is an object of the present invention to provide a lower body expander that is easy to carry and easy for anyone to use at home to prevent back pain.

[0005]

In order to achieve the above object, the present invention provides (a) a lumbar spine band 1 having corresponding fasteners 2 and 2 and a sole pad on which insertion portions 3 and 3 of both feet are mounted. Board 6
And (b) inserting the elastic cord 7 around the substantially rear half of the lumbar band 1, and (c) extending both ends 7a, 7 of the elastic cord 7.
It is a lower body expander configured by connecting a to the side portions 6a, 6a of the sole pad 6.

Further, in the above structure, the lower half body expander is configured so as to be vertically connected to the extension intermediate portion of the elastic string 7 via the connecting tool 8.

That is, structurally, the double structure of the bed for fixing to the lumbar region and the elastic string rounded to the lumbar region is integrated into one belt to enable stable operation. There is. More specifically, the elastic string rounded to the lumbar region produces a combined lateral force required for holding and a longitudinal force required for pulling on the lumbar region during towing, thereby squeezing the lumbar region. , The mechanism is such that traction is performed while performing twist correction.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In FIG. 1, reference numeral 1 is a lumbar band having corresponding fasteners 2 and 2 of Velcro Fastener, and 6 is a sole pad 6 on which insertion portions 3 and 3 of both feet are attached. A strip-shaped elastic cord 7 is inserted in a woven shape around the substantially rear half of the lumbar spine band 1, and the elastic cord 7 is connected to a connecting ring 9 at an intermediate portion of the extension.
The extension both ends 7a, 7a are elastically adjustably connected to the side portions 6a, 6a of the sole support plate 6 so as to be vertically connected via a connecting tool 8 including a hook 10 to form a lower body expander.

[0009]

As shown in FIGS. 2 and 3, a. Rotate the lumbar band 1 to the upper lumbar region and use the corresponding fastener 2
Fasten (Fig. 2 (a)). B. Insert both feet into the insertion part 3 and apply the soles to the contact plate 6 (FIG. 2 (a)). C. Sleep on your back (Fig. 3 (a)). D. The elastic action of the elastic string 7 (combination of pulling action and restoring action) is used to repeat horizontal and vertical bending movements of the leg and vertical and horizontal pulling of the waist ((a) of FIG. 3 and (b) of FIG. 3). .

During the above-mentioned operation (d), by extending the leg in the horizontal direction, it is necessary to hold the waist in the lumbar vertebra through the lumbar spine band 1 in which the elastic cord 7 wrapping around the lumbar region is woven. The lateral force and the longitudinal force required for traction are combined to generate squeezing and twisting of the lumbar region, and comfort is imparted to the entire lumbar region. As a result, it is effective for preventing back pain such as tight back. By expanding and contracting the elastic cords by the legs in this manner, the strength of the legs and the abdomen and the effects of pressing the back of the legs and acupressure can be simultaneously achieved by one operation.

The above horizontal and vertical bending movements are repeated
This leads to increased muscle strength in the legs and abdomen. Furthermore, the arch muzzle inserted from the insertion portion 3 is pressed by the sole pad plate 6 to improve blood circulation and promote the activation of multiple organs. Since both feet are aligned and exercised in a stable state, the forces are evenly distributed to the left and right, so that you can perform a well-balanced traction operation according to the basics of Oriental medicine, without being disappointed.

[0012]

As described above, the present invention is compact, can be folded and stored when not in use, and does not take up much space for carrying. Since it has a simple structure, it can be obtained at a relatively low cost. It can be easily used by anyone at home, and contributes to good health by pulling and correcting the lumbar spine, positively strengthening the muscles of the legs and abdomen, and acupressure of the sole at the same time.

Especially in the lumbar region, the lumbar band 1 in which the elastic cord 7 is woven is not tightened simply by the waist band. This is a major feature in that the lumbar region is comfortable as a whole because the forces of are generated in a combined manner to squeeze and correct the lumbar region. As a result, it is effective for preventing back pain such as tight back. Since the operation is performed in a supine state, there is no excessive fatigue during use, and pleasant fatigue is obtained after use. The elastic action of the expander can be freely changed by adjusting the elastic cord 7.
