Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a hula hoop, and more particularly, to a hula hoop capable of obtaining a sufficient exercise effect.

[0002]

2. Description of the Related Art Generally, a hula hoop is an exercise tool that trains the body by repeating a certain rotation using the waist of a human body, and has been spotlighted as an exercise tool that can be enjoyed by all people regardless of gender. .

As shown in FIG. 11, a conventional hula hoop 1 is formed by molding a plastic tube into a circular shape and connecting both ends to form a ring as a whole. Much bigger.

[0004] The usage of the hula hoop is as follows. First, while the hula hoop 1 is placed on the waist of the user, the rotation is repeated while giving elasticity to the waist of the user, and the hula hoop 1
Is continuously rotated by centrifugal force, but at this time, if the waist is moved without giving elasticity to the waist, the diameter of the hula hoop is larger than the waist line of the user, so the hula hoop does not rotate due to centrifugal force As a result, continuous movement cannot be performed, and the effect of exercise is not sufficiently obtained. Therefore, the user can naturally exercise by rotating the hula hoop by centrifugal force while continuously giving elasticity to the waist. Exercise using such a hula hoop is a beneficial exercise such as strengthening the user's waist muscle strength and cultivating the waist flexibility.

[0005]

The conventional hula hoop is:
There is a problem that the user is apt to get tired of the simple ring shape and gradually loses interest despite being a useful exercise means.

[0006] Further, since the hula hoop is a light-weight body having an empty interior, there is a problem that if the skill level is reduced, continuous rotation is difficult and the user is easily bored.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and a hula hoop capable of improving the structure and providing a more excellent exercise effect, and at the same time, allowing the user to fully enjoy the exercise. The purpose is to provide.

[0008]

The hula hoop of the present invention comprises:
It comprises a ring-shaped body and a number of projections provided on the inner peripheral surface of the ring-shaped body. The hula hoop of the present invention can be formed by dividing the ring-shaped main body into a plurality of unit bodies and assembling the unit bodies. In the hula hoop of the present invention, it is preferable that the protrusion provided on the ring-shaped main body has its tip portion directed toward the center of the ring-shaped main body. In the hula hoop of the present invention, the ring-shaped main body and the projection are separately formed, and the projection can be fixed to the inner peripheral surface of the ring-shaped main body with an adhesive or can be detachably attached.

[0009]

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 10 denotes a hula hoop of the present invention. The hula hoop 10 has a ring-shaped main body 10A formed by connecting a plurality of arc-shaped unit bodies 11. A plurality of V-shaped projections 20 are formed on the inner peripheral surface of each arc-shaped unit body 11 along the circumferential direction.

As shown in FIG. 2, each unit 11 has an outer diameter d at one end S smaller than an inner diameter D at the other end L.
A groove 12 is formed on the outer peripheral surface of one end S at a predetermined portion along the length direction, and the groove 1 is formed on an inner peripheral surface of the other end L.
A concave portion 13 that can be inserted into the groove 2 is formed along the insertion direction.

One end S and the other end L of each unit 11
Form a wrinkled tube and maintain a firm fastening when interconnected. This is because, at the time of assembling a large number of unit bodies 11, the fastening force of the connecting portion of the unit bodies 11 is reduced and the unit body 11 is not twisted.
This is for maintaining the neat ring-shaped main body 10A.

Each of the unit bodies 11 constitutes a ring-shaped main body 10A by connecting the required number of unit bodies by the user.
Each unit body 11 is generally formed of a relatively soft material. Therefore, since each unit is easily bent, it is possible to easily adjust whether the diameter of the hula hoop 10 is made larger or smaller than the reference.

Each projection 20 is substantially V-shaped in FIGS. 2 and 3, but may be U-shaped shown in FIG. 4, W-shaped shown in FIG. 5, or UU-shaped shown in FIG. That is, if the protrusion 20 has a shape that stimulates the area around the waist, the protrusion 20 has a V shape, a U shape,
It is not limited to a shape such as a W shape or a UU shape. Each projection 20
It is preferable that the tip is pointed toward the center of the hula hoop 10. By rotating the hula hoop 10, the area around the waist of the user can be stimulated.

Further, the projections 20 having various forms as described above are provided.
May be provided entirely along the inner peripheral surface of the hula hoop 10 or may be provided at regular intervals along the inner peripheral surface of the hula hoop 10. The projections 20 are preferably arranged symmetrically with respect to the center of the hula hoop 10.

Each projection 20 can be formed integrally with the unit body 11. However, in this case, the mold is very complicated,
Since the mold cost is too high, it is more preferable that the projections 20 are formed separately from the unit body 11 and connected to the unit body 11.

Furthermore, if the user gets tired of the shape of the projections or breaks any one of the projections when the projections 20 having a specific shape are combined with the hula hoop 10 and used for a long period of time, It is more effective to construct it in an assembled manner so that it can be easily replaced. Of course, the size of the projection 20 must be appropriately adjusted so as not to hinder the rotation of the hula hoop 10.

The ring-shaped body 10A and the projections 20 increase the effect of exercise when the projections 20 are heavy enough to give sufficient stimulation to the skin around the waist during rotation.

As in the prior art, both ends of the hula hoop 10 may be integrally formed so as to be in a ring shape by abutting both ends. However, it is more preferable to form the hula hoop 10 into a plurality of unit bodies 11 so as to be divided. .

The division of the hula hoop 10 into a plurality of unit bodies 11 facilitates storage and transport of the produced product, and also enables packaging, so that a higher-grade product is required. When hula hoops are not used, the storage space is minimized, and the user's physical condition (adults, children,
There are various advantages, such as adjusting the diameter of the hula hoop depending on the person who is fat or thin.

Hereinafter, the hula hoop 10 is divided into a plurality of unit bodies 1.
The connection between the unit bodies 11 in the case where the unit bodies 11 are formed by being divided into ones will be described.

In each unit 11, one end S and the other end L form a wrinkled tube, the outer diameter d of the one end S is smaller than the inner diameter D of the other end L, and a groove is formed on the outer peripheral surface of the one end S. 2 and a recess 13 is formed on the inner peripheral surface of the other end L.
As shown in the figure, the ring-shaped main body 10A formed by inserting one end S of the unit body 11 into the other end L of the adjacent unit body 11 has a state in which the adjacent unit bodies 11, 11 are firmly fastened. Maintain the unit 1 when assembling the multiple units 11
The fastening force of the connecting portions 1 and 11 is reduced, so that a proper ring shape is maintained without being twisted. When the required number of units 11 are combined by the user in the process of combining the units as described above, one ring-shaped hula hoop 10 can be formed. By making each unit body of a soft and easily bendable material, adjustment for making the diameter of the hula hoop 10 larger or smaller can be easily performed.

Hereinafter, the operation of the hula hoop of the present invention is as follows.

First, in the same manner as the conventional method of using the hula hoop, the hula hoop 10 is continuously rotated by centrifugal force while repeatedly rotating while giving elasticity to the waist while the hula hoop 10 is in contact with the waist. In this case, in use, it is better to exercise in a state of wearing thin clothes as much as possible so that the projection 20 can easily stimulate the area around the user's waist.

As described above, the hula hoop 10 rotated by the motion of the waist of the user has a plurality of projections 2 on its inner peripheral surface.
Since 0 is formed, the projections 20 apply a constant pressure together with stimulation to the skin while rotating along the waist of the user during rotation, thereby exhibiting a kind of acupressure effect. This acupressure effect utilizes the effect of rubbing a part of the muscle with a finger to loosen the hard muscles at that part.

Accordingly, in the hula hoop 10 of the present invention, the tip of the projection 20 is pointed like a finger. Stimulates and produces a relaxing effect. At this time, the projection 20 has a pointed tip at the point of direct contact with the skin, and the hula hoop is a weight body having a constant weight. Therefore, the effect of the projection 20 stimulating the skin is sufficient.

The hula hoop 10 according to the present invention has a protrusion 20
May be provided entirely along the inner peripheral surface, or may be partially symmetrically disposed along the inner peripheral surface at a fixed interval with respect to the center of the hula hoop 10 so that the weight of the projection 20 during rotation is reduced. And smooth rotation is possible.

[0028]

The above-mentioned hula hoop of the present invention has the following effects by having a plurality of projections with sharp points on the inner peripheral surface.

1. When the user exercises, the protrusion formed on the inner peripheral surface of the hula hoop stimulates the skin by the rotation of the hula hoop, thereby increasing the exercise effect such as obtaining an acupressure effect.

2. It is possible to prevent the user from getting tired easily by a simple form, and to make the user enjoy the exercise.

3. When the hula hoop is divided into a plurality of parts, storage and transportation are easy, and packaging is possible, so that a high-grade product is realized.
