The present invention relates to a whey sphere that combines waist movement.

In general, it is known as a hula hoop (HULA HOOP) as a back exercise equipment. The structure of this hula hoop is a circular trajectory with a circular cross section whose diameter is larger than that of the waist, and is shaped like a donut, and its diameter is such that it is sufficiently sized to maintain sufficient inertia for rotation when it is located at the user's waist (about IM Inside and outside), and has been used for sports and social activities. Such a conventional hula hoop has a lack of exercise effect, and at the same time, there is no wandering effect due to a simple repetition of exercise, and the situation is avoided. That is, as described above, the hula hoop is rotated around the waist by wearing a circular ring larger than the waist and having a large circular ring on the waist, and simply swinging the waist. You can't expect your back, so you'll get tired of using it for a short period of time with a certain sense of speed, so you won't get a lasting exercise and a wandering effect. In view of the above problems and inconveniences in use, as I have revealed in Korean Utility Model Registration Application No. 92-10204, the inertial body is installed by means of inertia by installing the inertial body by the connecting means outside the circular ring body. Or it has been proposed that the inertial body is made to operate by rotating with the ring body. According to this structure, the ring body has a size slightly larger than the waist size of the user, and connects the inertia body by the connecting means to the outside thereof, and the connecting means and the joint of the ring body are provided with a rotation means to the body by the swing of the waist. In the proximate position, the ring body and the inertial body relatively far from the body by the connecting means are rotated, respectively, so that it is possible to enjoy entertainment and exercise together. However, this requires highly skilled and repeated practice to rotate the two rotors at different circumferential speeds, or to perform back swings at the same circumferential speed, such as infants and housewives. Difficult to use for users with relatively weak exercise nerves have been followed. In addition, depending on the physical condition of the wearer, there was also the inconvenience of having to produce and distribute several finishes for each diameter size.

The purpose of the present invention is to provide a wandering exercise equipment that can be widely used for both housewives and infants, as well as adults and young adults with a lot of athletic nerves.

Another object of the present invention is to provide a waist exercise gyrus that can be used by anyone with any physical condition (waist size).

Another object of the present invention is to provide a process for wearing in a solid state, and a waist exercise wedge which can be easily disassembled from the body.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The present invention has a circular donut shape and is connected to the hinge means 60 to be rotated in a state where one end is coupled to each other, and the left side is worn outward of the body waist in a state where the separation boundary of the other end is separated from each other. A ring portion 10 in which a rail hole 13 is dug in the cross section of the right pair of ring bodies 11 and 12 and the guide groove 15 is opened outward; An inertial portion 20 which is guided to the upper ring portion 10 to be rotated and provided with a weight body 21 having a predetermined weight to gradually add inertia and centrifugal force; A connection part 30 connecting the ring part 10 to prevent the separation of the inertia part 20 during rotation; A rotating part 40 performing rolling motion to reduce frictional resistance when the weight body 21 connected by the connecting part 30 is rotated along the trajectory of the ray hole 13 by the guide of the ring part 10; The ring body 11 and 12 are coupled to form a circular trajectory to the position of the other separation boundary on which the hinge means 60 of the ring bodies 11 and 12 are installed, and the hook ring 33 is formed to disassemble. In the configuration consisting of the binding unit 50 is installed and the male body 53; The inertia part may be disposed in the ring part 10 by placing a separate hoop 15 having a diameter larger than that of the ring bodies 11 and 12 between the connection parts 30 connected to the inertia part 20 to the outside thereof. The hoop 15 is installed to be rotated together, and the weight 21 is characterized in that the configuration is configured so that the air passes through the sound when the sound is rotated through the vocal holes 24 of different sizes.

The ring part 10 has a corresponding inner diameter in consideration of the waist size of the user, and is a structural part that is worn in a state of being hung on the waist by connecting the ring body 11 having a predetermined cross section in an annular shape.

The ring body 11 is formed of a synthetic resin material, the shape of the cross section is hollow in the state that the hole 13 is formed in the inside in consideration of the user's desired design such as square, circle, other hexagon, octagon The shape is set and molded.

Since the ray hole 13 is excavated along the ring bodies 11 and 12 leading to the same cross section, the rail holes 13 abut the same position while the pair of ring bodies 11 and 12 are coupled. The rotating part 40, which is connected to the rail hole 13 and assembled to the molded position, may rotate around the ring part 10.

In addition, the guide hole 15 is opened to the lay hole 13 to the outside, the rotating part 40 is connected to the connecting portion 30 in the state fitted to the rail hole 13 to be rotated outwards. To help.

The opened position of the guide groove 15 is formed to be symmetrical about the center of the ring bodies 11 and 12, and FIGS. 2 and 5 are provided to reinforce the ring bodies 11 and 12. As shown in the figure, it is preferable to mold the vertical flesh 16 to have an integral vertical cross section because durability is increased.

The ring portion 10 having such a configuration is different in size in consideration of the size of the user's waist size in order to maintain a close contact force not to rotate with the inertial portion 20 in a state worn on the waist of the user's body For example, the maximum waist size and the minimum waist of a person that can be used to produce the inner diameters of the three ring portions 10 such as large, medium, and small, or to have a more accurate and comfortable wearing state. It is necessary to shape the size into approximately five to six different types.

Therefore, the smallest size is worn by infants and women, the middle size is matched to the size of the average person, and the size of the size is available to the ship's ships and, if necessary, large, medium and small. It is good to produce the median size again in the size-divided state so that the user can select the appropriate one for his waist size and wear it in the proper state to use for exercise.

Thus, it is difficult to install the ring portion 10 formed in consideration of the dimensions that are in close contact with the waist of the user to fit through the upper or lower part of the body.

That is, compared to the size of the waist, the shoulder portion located on the upper side and the size of the buttocks located on the lower side are larger than the size of the waist, so that the ring portion 10 is a pair of left and right rings at the waist position. (12) to be separated so that the ring body (11) (12) at one end to the mutual flow is made around the hinge means (60), the other end of the state worn by the binding portion (50) To keep it.

As shown in FIG. 4, the hinge means 60 extends the ring body 11 and 12 integrally with the method of allowing the hinge pin 61 to be fitted into the engaged position so that the hinge pin 61 can rotate about the hinge pin 61. As shown in FIG. In the bending position of the joint portion 63 formed so that the hinge operation is made using the characteristics of the synthetic resin material having good toughness, and although not shown, the ring body 11, 12 may be attached even if a normal hinge is attached to the outside of the boundary portion. The opening and closing operation can be performed in the state that the joints of the two parts are not completely separated from each other.

The inertial portion 20 is a structural portion that is connected to the ring portion 10 to impart inertia to the ring body 11 at the time of back swing to cause strong back swing with increasing rotation speed.

Therefore, the weight body 21 constituting the inertial portion 20 is rotated together with the ring body 11 in a state in which a certain distance from the ring body 11, and has a centrifugal force in the outward direction from the center of the ring portion 10 As a result of having the velocity component in the direction of rotation of the centrifugal force, the velocity component is a cause of gradually increasing.

The weight 21 is a rubber material or a synthetic resin material suitable for the material having a flexible and elastic surface in order to prevent the danger occurs when in contact with other people or objects around the use, the spherical shape commonly used a lot It is good to make a ball-like shape with a little weight.

In addition, the weight of the weight 21 is selected to have an inertial force by the guide of the ring portion 10 and obtained by the experiment to have a proper rotation speed when rotated, the inertial force required according to the user's ability is different Since it is, it is preferable to make a plurality of different types of weights in equal parts, so that the user can select a suitable weight to be used in combination with the connection portion 30.

The weight 21 has a weight that affects the centrifugal force and the inertia force, and its size and shape are independent of operation, but in consideration of storage, the weight 21 corresponds to the size between the tennis ball and the handball ball. It is suitable.

In addition, if the weight body 21 drills the vocal holes 24 in a number of different sizes, when it is rotated rapidly, the surrounding air passes through a hole of a size suitable for the corresponding speed, and it is like blowing a flute. In addition, the sound of the sound, such as whistle blowing, it is effective to feel the novelty during exercise.

The connecting portion 30 is a structural portion connecting the ring portion 10 and the inertial portion 20 to rotate together.

Therefore, the inertial portion 20 is fixedly connected to the members that are not separated from each other in a state where the inertia portion 20 is maintained from the ring portion 10, as shown in the drawing. One end of the 31 is pivotally fitted to the ring portion 10 so as to rotate, and the other end is fixed to one side of the weight body 21, respectively.

In the case of using the string 31 as the connecting portion 30, the rib 43 is integrally formed on the support 41 of the pivot 40, and the rib 43 and the string 31 are woven together. It is fixed by the method, and the end is to be directly bonded to the spherical weight body 21, or to make a connection by punching a hole through the work to be woven.

Also, as shown in FIG. 8, the weight body 21 also has a separate support piece 22 integrally formed so that the same effect can be obtained even when the string 31 is woven together.

At this time, the hook ring 33 is provided at the end of the string 31 so that the support piece 22 is hooked to the hook ring 33, which is convenient at the time of replacing the weight 21.

The structure of the locking ring 33 is inserted into the hole drilled in the support piece 22 by the moving piece 34 to elastically move and intercept the opened ring portion to maintain the locking state, the other weight 21 If it needs to be replaced by the moving piece 34 by moving the one side of the ring to open it in the state to be coupled to the support piece 22 of the other weight body 21 is to be replaced quickly It can be.

The string 31 is not normally deformed in the longitudinal direction, which is always maintained at a constant distance from the waist position of the centripetal axis during the rotation of the weight body 21 and the weight body 21 of the inertia portion 20 is It will be effective to rotate.

The connecting portion 30 may be a rod that does not stretch in the longitudinal direction, and always maintains a given shape and length without flexibility, and also uses a string 31 having good elasticity and elastic force, and also changes in acceleration force. It is desirable to be able to expect.

That is, when the rotational speed of the weight body 21 is increased and the centrifugal force is increased by using a spring elastically deformable in its longitudinal direction or a spring wound in a coil shape having a relatively small diameter although not shown, the connection is increased. The result is that the length is increased proportionally.

Therefore, since the distance from the waist position to the weight body 21 is variable and the increase in centrifugal force can be expected at this time, the change can feel a variety of rotational speed and feeling of regret.

In this way, if the change in rotational speed is added by inertial force, the waist motion can be more effectively performed, and the positional reinforcement effect such as not only the exercise effect but also the weight of the waist can be obtained.

And, between the connecting portion 30 and the ring body 11, 12 is provided with a rotating portion 40 to reduce the rotational friction with the ring portion 10 is stopped, the centrifugal force of the inertial portion 20 In the perpendicular direction, the weight 21 makes the rotation operation more smoothly.

This makes it possible to obtain a desired rotational speed by oscillation of the waist so that it can have more dynamic movement and wandering effect.

That is, the inertia part is provided in the state in which the spherical roller 42 is installed up and down freely on the support body 41 so as to be in contact with the inner wall of the rail hole 13 which is dug into the ring bodies 11 and 12. When the 20 and the connection part 30 is rotated, the rolling operation is performed in a state where there is almost no resistance.

Accordingly, the connecting portion 30 and the weight 21 connected thereto are rotated by the guides of the ring bodies 11 and 12 in response to the operation of the oscillator to perform the rocking motion, and the rail hole 13. The inertia portion 20, the connecting portion 30, and the rotating portion 40 are rotated together in a substantially straight line along a circular trajectory.

12 shows a state in which the roller 42 is rotatably fitted around the center pin 44 to the pivot 40.

That is, two rollers 42 are installed on both sides of the support 41 in a symmetrical manner with respect to the center position where the string 31 of the connecting portion 30 is connected, and four rollers 42 having the same structure up and down, respectively. The rotational movement is performed in the state of contacting the inner wall surface of the rail hole 13 at the same time, so that the two points are stably formed in the rotational direction as well as the balance between the upper and lower sides in the rotational direction without noise or vibration. It is possible to perform the rotation operation of the weight body 21.

The roller 42 installed for the rolling contact has an outer surface shape of a spherical ball shape, but may be provided with a cylindrical roller shape.

In this way, when the coupling between the ring body 11 and the connecting portion 30 freely rotated by the rotating portion 40, the ring portion 10 is worn in a position corresponding to the length of the connecting portion 30 to the outside The weight 21 of the inertia portion 20 sags by its own weight.

When operating for the first time in this state, the user lifts up the weight 21 and at the same time sets the desired rotational direction of the weight 21 at the same time so that the rotation is performed with a slight force, and then continues the back swing By the moment of inertia is gradually added to the motion is to be stopped without stopping.

In addition, conditions in which the rotational speed of the inertial part 20 may be different, for example, frictional resistance between the rotating part 40 and the ring body 11, the weight of the weight body 21, the swinging speed of the waist, etc. The skill of the skilled person is required for the operation to rotate properly at a desired speed due to the difference of, and in spite of these conditions, if the swing position of the waist coincides with the rotational position of the weight body 21, the rapid rotation is gradually accelerated by the force. There is a number.

In addition, when decelerating this speed, even if the rotation of the waist stops, the rotating part 40 coupled to the rail hole 13 of the ring bodies 11 and 12 reduces the frictional resistance of the inertia part 20. Rotating motion can be continued to some extent, so that the speed can be adjusted slowly.

As shown in FIG. 7 as the configuration of the rotating part 40, the cross section of the ring bodies 11 and 12 is hollowed so that the ray hole 13 is dug, and the center of the outer direction thereof is centered. The guide groove 15 is formed to be opened so that the rollers 42 rotatably coupled up and down of the support body 41 make rolling contact with the ring body 11 and smoothly rotate.

In this case, by splitting the ring bodies 11 and 12 symmetrically by the method of forming the guide grooves 15 in the ring bodies 11 and 12 and then screwing them using screws 18, In addition, the assembly is made smoothly by the method of bonding by an adhesive or heating, so as to facilitate the assembly work.

According to another embodiment as shown in FIG. 14, the connecting portion connected to the inertia portion 20 by positioning the hoop 14 having a diameter slightly larger than the ring bodies 11 and 12 outside the ring portion 10. An embodiment in which 30 and the rotating part 40 can be rotated together with the inertial part 20 is illustrated.

In this case, the string 31 of the connecting portion 30 positioned outside the hoop 15 is woven to the hoop 15 to be fixed, and the inner surface of the hoop 15 and the rail hole of the ring portion 10. The weight of the inertial portion 20 in a state in which a predetermined distance from the ring portion 10 is always connected to the connecting rod 32 by connecting rods 32 which are not deformed in length with the pivoting portion 40 coupled to (13). When the sieve 21 is rotated, the hops 15 may be rotated together.

Therefore, since more skilled technique and effort are required as compared to only the weight 21 of the inertia portion 20 being rotated around the ring portion 10, it is suitable for a user who has accumulated many economic wheels.

The binding part 50 is a structural part detachable by a simple operation so that the ring part 10 having a dimension suitable for an entity can be firmly coupled in a state in which the ring part 10 is decomposed into a pair of ring bodies 11 and 12.

That is, the ring portion 10 is manufactured by dividing the circumference to have a size of about 1/2 of the circumferential length in consideration of the manufacturability, and to be worn on both sides of the waist in a separated state, wherein the pair is separated The ring bodies 11 and 12 are to be coupled to each other at the boundary position and to be separated again.

2 and 3 show an embodiment of the fastening part 50. Hooks 51 are formed at opposite ends of any one of the ring parts 11 of the ring part 10 such that the hooks 51 face outwardly and are coupled thereto. The other ring body 12 is made to be engaged by making the hook 51 to be hooked up and down at the same time by drilling the catching hole 52 to a position where the hook 51 can be caught. It shows what to do.

It is molded when the hook 51 is formed of a resin material and elasticity meets the inner surface of the ring body 12 at the position of the inclined surface is crushed, and is caught when it is unfolded by the restoring force at the position of the locking hole 52 In order to release the binding state as necessary, it is possible to separate the locking position by applying an artificial force inward from the position of the locking hole 52 so as to shift the locking position.

Since the ring portion 10 is divided into two structures, the boundary is formed at both ends, so that the ring portions 10 are installed in the same formation and structure.

The hook 51 and the engaging hole 52 is the support body of the rotating part 40 at the position of the rail hole 13 when the vertical bar 16 is integrally molded to the ring bodies 11 and 12. Since the 41 is rotated, the rail hole 130 is formed to be positioned on the other side where the rail hole 130 is positioned, that is, the rear surface of the vertical bar 16.

In addition, even though the centrifugal force is strongly acted upon by the swinging of the inertial part 20, the hooks 51 are formed up and down so that the ring bodies 11 and 12 are not separated in the bound state and can be supported. It is good to form the support piece 55 integrally.

The support piece 55 maintains a balance therebetween when the hawks 51 elastically flow inward and outward, and increases the bearing force.

10 is a view showing another embodiment of the fastening part 50, and a separate male body 53 formed to protrude the hooks 51 and the support piece 55, and the hook 51 can be caught. Each of the arm bodies 54 to which the catching holes 52 are inserted so as to be separately screwed to each joint boundary of the ring bodies 11 and 12 using bolts, or applied to heat to bond in a molten state Fixing and installing by the method of thermal fusion, or by the method of triad using an adhesive so that the binding and disassembly is made in the separation surface of the ring bodies (11, 12) as above.

According to the structure in which attachment and detachment are performed by the binding unit 50 at both boundary portions of the ring bodies 11 and 12 divided in this manner, the ring bodies 11 and 12 are completely separated, and thus any There is a risk of losing one ring body (11, 12), and there is a possibility of causing inconvenience in the method of operating so that the hook 51 is fixed and disassembled on both sides at the same time.

Therefore, it is preferable that the hinge means 60 is installed at any one of the joints of the ring bodies 11 and 12 so as to be rotated about one support point in the already coupled state.

4 shows that the ring bodies 11 and 12 are swung around the hinge pins 61 by inserting the hinge pins 61 into the connection position.

FIG. 5 shows that the joint 63 is formed in a continuous state without separating the outer wall flesh members of the ring bodies 11 and 12, and the hinge operation is performed without installing a separate paper pin for the use of the flexibility of the synthetic resin material. It shows what is being done. The material needs to be formed of a tough material having flexibility and toughness in the synthetic resin material, and the joints 63 are repeated by repeating the ring bodies 11 and 12 extending beyond the elastic limit of the material. It is good to install the intermittent member 19 to prevent cutting).

That is, as shown in FIG. 9, the slit 17 'is made to have a thickness corresponding to the intermittent member 19 on the support body 17 with the intermittent member 19 of the letter “I” of the English letter. By being fitted, the ringing members 11 and 12 are interrupted so as not to be held apart from the position of the locking jaw 19 'protruding downward from the yarn end of the intermittent member 19.

Therefore, since the length of the locking projections 19 'protruding on both sides of the intermittent member 19 sets the limit in which the ring bodies 11 and 12 can be opened, the ring body formed of synthetic resin is calculated for this dimension ( 11) It is designed so that the joint part 63 will not be damaged even by repeated use in consideration of the elastic limit and the fatigue limit of (12).

In addition, as a means for preventing the breakage of the hinge joint 63, it is preferable that the flexible member is made of a synthetic resin material having a good thickness so that the plate member 62 is formed with a thin thickness so as to be reinforced on the outer side.

Thus, the hinge means 60 is provided on one side of the ring bodies 11 and 12, and the binding unit 50 is installed on the other side of the ring body 11, 12, and the body is worn and separated by a quick and convenient method in one operation. To make things work.

In addition, by fixing the elastic band 71 holding the elastic force into the ring portion 10, the tightening portion 70 to be worn by varying the tightening size elastically corresponding to the waist size of the body. It is good to install.

That is, since the size range of the waist that can be worn is determined according to the inner diameter of the ring portion 10, the ring portion 10 is made larger in order to direct the manufacture of the ring portions 10 for each of several sizes. The elastic band 71 is elastically fixed to the body by fixing the elastic band 71, which is elastically deformed, in a triangular shape, or a quadrilateral shape or a quadrilateral shape, after fabricating the shape of the branch. It is to be tightened so as to be worn by a user having any waist dimension.

The elastic band 71 is a rubber material or urethane rubber having excellent elasticity, as shown in FIG. 6, or a string of a certain thickness, or a wide band section as shown in FIG. 13. In addition, it is more efficient in terms of tightening effect and stability to select the same wide band type as the latter for tightening in the state worn on the body.

11 is an elastic band 71 is fastened to the two loops 72, both ends are fixed to the female body 54 and the male body 53 of the fastening portion 50, respectively, the overall tightening portion 70 of the square Shows a state in which is formed.

This state is a state that is not worn on the body, the distance distance that is opposed in the state of maintaining the straight line of the elastic bands 71 has a width smaller than the user's smallest waist size.

And, when worn on the body as shown in the imaginary line is elastically opened so that the wear is made in a tightened state.

The elastic band 71 is to be opened and tightened together by the detachable operation of the binding unit 50, the user can be made to wear a variety of waist dimensions in a single model form, Very advantageous in terms of

The present invention having such a structure can obtain a waist movement effect by swinging the waist by wearing on the waist.

In addition, by holding the ring portion 10 with both hands and swinging the arm in an extended state, the arm and shoulder movement effects can be obtained.

In addition, after placing the ring portion near the neck, both hands are placed inside the ring portion to maintain a solid wearing state, and thus the neck movement effect can be obtained.

Then, by placing the ring portion between the two feet in the state of lying down the upper body, by slowly swinging the foot can also have the effect of foot movement, as well as the waist, the effect of the whole body movement can be obtained.

The present invention as described above, first, to maintain a certain distance from the center of the ring portion can be added centrifugal force and inertial force according to the rotational speed, so that the user feels a variety of speed and amusement with proper rotation control. Secondly, the centrifugal force generated at this time acts on the waist to provide the body's balance effect such as making the waist more flexible and stronger. Also, since the third ring does not flow down while being worn on the body, only the weight rotates around it. Anyone who has relatively dull exercise nerves can use it, so both children and adults can use it as a full-body exercise. Fourth, the elastically deformable tightening portion is installed in the ring portion can be worn by any wearer having any dimension, the fifth is a very useful design, such that it can be made easy to wear and detach the ring portion. .
