Abstract

PURPOSE: A hula-hoop having several protrusions for applying pressure is provided to facilitate the fastening and the separation of each units of the hula-hoop, to elastically compress the abdominal region, and to increase the fastening force of the protrusions. CONSTITUTION: The hula-hoop is constructed by separably assembling several unit members into a ring form, and comprises a pressure protrusion(30) arranged at regular distances along the inner peripheral of the hula-hoop. The pressure protrusion is formed by coupling an empty hemispherical upper member(31) and an empty hemispherical lower member(32) facing each other. A recess is formed along the inner peripheral on the coupling end of the upper member, and an inclined convex portion is formed along the inner peripheral on the coupling end of the lower member. A rubber magnet(34) made of rubber and magnet powder is fitted on the apex portion of the upper member to absorb the shock generated when the pressure protrusion compresses the body of a user.

Description

Hula hoop having acupressure projections {A HULA-HOOP HAVING PROTRUSION FOR APPLYING PRESSURE}

The present invention relates to a hula hoop, and more particularly, to improve the structure of the hula hoop in which divided units having a plurality of protrusions are joined to each other along the inner circumference to form a ring, and each end of the divided end is capable of adjusting the diameter of the ring. It is easy to disassemble and assemble, and it has a stable bonding force, and the acupressure protrusions can be partially replaced, while stimulating the acupuncture points and the meridians of the human body when the hula hoop rotates, and at the same time, it has a beautiful structure. It relates to a hula hoop having acupressure projections to have.

In general, a hula hoop is a ring-shaped tube made of a pipe-like plastic material, and when it is rotated in a state of being worn around the waist of the human body, and a constant recoil is repeatedly applied to the waist, the hula hoop generates a rotational centrifugal force, Pressed repeatedly, it is used as an exercise device to solve waist flexibility and strength and abdominal obesity.

However, the hula hoop is made of a simple ring-shaped pipe structure is rotated to contact the waist of the human body at the time of rotation, with a slight amount of pressure, the hula hoop is made of a slippery outer surface of the beginner or athletic nerve is dull When used by people, the hula hoop often slips from the waist, making it easy to give up or demonstrate hula hoop exercise.

In addition, in order to increase abdominal obesity and waist flexibility using the hula hoop, as the slippery outer surface of the hula hoop repeatedly rotates in a state of wrapping the waist, the amount of exercise may be solved.

In addition, the above-described hula hoop is made of an integral ring type having a larger diameter than the waist of a general person, so that the transport of the hula hoop is difficult when transporting to a playground or a park in a mountain and a narrow road. .

In order to solve such a conventional problem, a hula hoop provided with acupressure protrusions on the inner circumferential surface and a splitable hula hoop have been proposed by the present applicant as Utility Model Registration No. 98-6042 and Patent Application No. 98-43087. 1, the ring-shaped body 1 is divided into a plurality of units 2 and each end of the units 2 is fitted to each other, so as to disassemble the hula hoop during movement, as shown in FIG. It becomes possible, and during exercise to enjoy the hula hoop after assembly by fitting these units (2).

In addition, the inner circumferential surface of the hula hoop having a plurality of projections (3) along the circumference, the plurality of projections (3) during the hula hoop movement due to the back reaction by pressing the menstrual blood and the jugular part of the lower back to have the effect of acupressure It is to be.

The hula hoop, because the projections support the waist portion during rotation is solved the problem of slipping from the waist during exercise, and also increases the centrifugal force during rotation by increasing the weight of the projections, as well as the rotation of the lumbar spine and Strong pressure on the menstrual blood will be able to achieve a greater acupressure effect.

However, the above-described hula hoop is also divided into the unit of each other by the interference fit method, so that the joint parts that are bonded to each other when the use of a long time or impact occurs loses the elasticity, and also when foreign matter is caught in the joint part, disassembly is There is a problem that becomes difficult.

In addition, if the protrusions formed along the inner circumferential surface of the hula hoop are integrally formed and one of the protrusions is broken, there is a problem that the whole unit or the hula hoop is divided.

Accordingly, the present invention has been made to solve the above problems, by rotating the coupling provided in the connecting end of each of the plurality of divided units, the purpose is to enable a stable coupling force and easy disassembly.

Another object of the present invention is to allow the acupressure projections to elastically press the back of the exerciser during the hula hoop movement by fitting the rubber magnet to the ridge apex of the protrusion provided on the inner circumferential surface of the ring-shaped body.

Still another object according to the present invention is to allow the acupressure projection to be fitted to the inner circumferential surface of the hula hoop while having a stable fixing force.

Another object of the present invention is to allow the acupressure projections to be made up of a pair of upper and lower projection members, so that only the upper projection members can be replaced to variously change their appearance.

In order to exercise with the assembled hula hoop, the hula hoop is rotated in a certain direction while the waist is worn on the waist, and the recoil is repeatedly applied to the waist, causing the hula hoop to generate centrifugal force continuously around the human waist. The jam will rotate.

At this time, the acupressure protrusions 30 provided on the inner circumferential surface of the hula hoop are repeatedly rotated in a state of pressing around the waist to stimulate the menstrual blood and the cervical veins of the waist and at the same time provided on the upper protrusion member 31 of the acupressure protrusions 30. The rubber magnet 34 is repeatedly contacted around the waist while penetrating the drug such as magnetic fields contained in the rubber magnet 34 into the human body to obtain a therapeutic effect such as low back pain.

Therefore, the hula hoop using the acupressure projections and the projections according to the present invention, each unit constituting the hula hoop is formed to a predetermined size to be able to adjust the size of the hula hoop to suit the user's taste, and also Since the respective units are tightened and fixed by the coupling, there is an effect of preventing twisting or detachment during use.

In addition, the acupressure protrusions provided along the inner circumference of the hula hoop prevent the slipping and increase the centrifugal force during the rotation of the hula hoop. The effect of enjoying the exercise by selecting the back, that is, it is possible to replace acupressure protrusions having a variety of colors or shapes, so that the user can enjoy the exercise without feeling proof.

In addition, by combining rubber magnets at the apical peaks of the acupressure protrusions, which repeatedly press the periphery of the waist, while touching the human body during the rotation of the hula hoop, the acupuncture points and the meridians of the waist area are pressed and oxygen is supplied to the blood circulation. It has the effect of promoting this.
