Description

  The present invention relates to an auxiliary tool used for easily moving a hip joint.

  While being said to be a super-aged society, there are many people who have low back pain and knee pain, especially middle-aged and elderly people who lack exercise. There are various reasons for this, but it is said that back pain and knee pain can be reduced or prevented by appropriately stretching (stretching) the hip joint. Hip stretching exercises are said to be particularly effective in preventing falls of elderly people, leading to fracture prevention and health maintenance.

Various methods have been proposed for hip joint stretching exercise. For example, exercises that stretch the hip joint by sitting on the floor and opening both legs forward and bending forward, and exercises that extend the hip joint by opening and closing both legs greatly with a training device such as a gymnasium are known. ing.
However, for middle-aged and elderly people who lack exercise regularly, these trainings are difficult to implement, so it is desirable that they can be done more easily and easily at home and in nursing care facilities.

Things you can easily do at home are sitting on a chair, opening and closing your legs a few times and closing them multiple times, or holding a slightly softer ball between your knees and holding them down from both sides. It may be possible to repeat maintaining several seconds for several times.
However, if you hold the ball between your knees for several seconds and then spread your legs a little, the ball will fall. It is somewhat troublesome to put the ball between the knees each time, and it becomes a factor that hinders the willingness to exercise.

  On the other hand, if both legs are opened too much while sitting down, the posture becomes worse and accompanied by a feeling of fatigue. If both legs are too open, the back and back may hurt. In order to prevent such a situation, the present inventor has proposed an open leg restraining tool in Patent Document 1. Even with the leg-opening restraint described in Patent Document 1, it is not inconvenient, although the ball cannot be sandwiched between both legs.

Utility model registration No. 3201770

  Therefore, the problem to be solved by the present invention is that it can be used easily when sitting on a chair or the like. The ball is sandwiched between the thighs of both legs (near both knees), and both legs are directed toward the center of the ball. Therefore, it is intended to provide a tool for assisting in the exercise of repeatedly applying force so as not to drop and repeatedly opening both legs so as not to open too much. In addition, an object of the present invention is to provide a device that can suppress excessive leg opening when sitting on a chair or the like.

In order to solve the above-described problem, a hip joint exercise aid according to one aspect of the present invention includes a left leg wound around a left leg, a right leg wound around a right leg, the left leg, and the right leg. And a ball storage portion configured to hold or store the ball, and at least the vicinity of the ball storage portion is configured to be stretchable in the longitudinal direction. It is characterized by.
The “near the ball storage portion” is a portion of the left leg portion and the right leg portion that is close to the ball storage portion, and is a portion that is located between both legs when used.

  In this specification, the “storage” of the “ball storage unit” does not necessarily mean “stood” so that the ball is completely invisible, and a part of the ball may be visible. In the state of use, when both legs are opened (when both legs are not holding the ball), the lower part of the ball may be supported so that the ball does not fall.

  By providing the ball storage portion between the left leg portion and the right leg portion, the ball can be sandwiched between both legs, and the ball can be prevented from falling when both legs are opened. Since at least the vicinity of the ball storage portion is configured to have elasticity in the longitudinal direction, both the legs can be opened and closed by storing the ball in the ball storage portion. In other words, it is possible to easily perform a hip joint stretching exercise that repeatedly suppresses both sides and slightly opens both knees. Therefore, according to the present invention, the hip joint stretching exercise can be easily performed even at home.

  By wrapping each leg part generally connected to the ball storage part around each leg, it is possible to prevent the legs from opening too much when the legs are opened and closed. Therefore, according to the present invention, excessive leg opening can be suppressed.

  In the hip joint exercise assisting device according to one aspect of the present invention, the ball storage portion is made of a belt-like member provided with a fastening member at both ends, and can be held in an annular shape by being wound according to the size of the ball. You may be comprised so that it may become.

  In the hip joint exercise assisting device according to one aspect of the present invention, the ball storage portion is made of a stretchable material, is configured in advance to be annular, one end is connected to the left leg, and the other end is the right leg. When connected, it may be characterized by spreading to a size that can accommodate one ball.

  In the hip joint exercise assisting device according to one aspect of the present invention, the ball storage portion is divided into two parts, and each of them may be of a size that can store one smaller ball.

  Further, as a constituent requirement of the hip joint exercise assisting device according to one aspect of the present invention, the ball is not essential, but the ball to be used is assumed to be pressed near the knees of both legs and thighs. Balls having moderate elasticity such as urethane and resin are preferable, and hard balls are not suitable. What is marketed and can be normally obtained can be utilized suitably.

  Since the configuration as described above is adopted, according to the present invention, it is possible to provide assistance for easily performing hip joint stretching exercise and suppressing excessive open legs. In other words, the ball can be sandwiched between both knees and force can be applied to the inside so that it does not drop and the movement of opening both legs can be assisted, and excessive leg opening can be suppressed. Can do.

(First embodiment)
A first embodiment for carrying out the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a schematic view of a use state in which the hip joint exercise assisting device of the present embodiment is wound around the thighs of both legs and the ball is stored, as viewed from the front. FIG. 2 is a schematic perspective view seen obliquely from above with the hip joint exercise assisting device of the present embodiment opened.

  In FIG. 2, the area | region which attached | subjected the thin some line has shown that the part has the stretchability of a longitudinal direction at least. For example, it is composed of a cloth containing urethane or the like (spandex or the like) or a stretchable material such as rubber. The area | region which attached | subjected the fine dots or mesh has shown that the part is a fastening member (for example, a hook_and_loop | surface fastener, a hook, etc.).

  As shown in FIGS. 1 and 2, the hip joint exercise assisting device 1 according to an embodiment of the present invention has a long and narrow band shape (band shape) as a whole, and a left leg portion wound around the left leg and a right leg portion. A right leg portion to be wound, and a ball storage portion 2 between them, that is, in the central portion. The hip joint exercise assisting tool 1 is made of a flexible material such as cloth or rubber so as to be wound around a leg or a ball. The substantially center (reference numeral C) in the longitudinal direction is firmly fixed by, for example, canning or crimping in the lateral direction. As shown in the drawing, both sides of the center C are divided into two forks (in FIG. 2, a portion 3 on the upper side of the drawing and portions 4, 8 and 9 on the lower side of the drawing). The upper band (symbol 3) in the drawing is further divided into two forks from the middle of each of the left and right sides (symbol 7).

  The band 3 on the upper side of the drawing in FIG. The belt 3 serving as the ball storage portion 2 has fastening members 6a and 6b at both ends, and is configured to be annular by fitting the fastening members 6a and 6b to each other. Specifically, a hook-and-loop fastener 6b (B surface: loop surface) is stitched to the surface of one end (the left side in the drawing) of the belt 3 that is outside when wound, and the other end (the right side in the drawing). ), The surface fastener 6a (A surface: hook surface) is stitched to the inner surface when wound. Thereby, the ball storage part 2 (band 3) can wind the ball and store the ball inside, and is firmly fixed in an annular shape by fitting the A and B surfaces of the hook-and-loop fasteners at both ends. Is done. The length of the belt 3 serving as the ball storage portion 2 is appropriately selected according to the size of the ball stored inside. Further, the belt 3 serving as the ball storage portion 2 may be made of a material having elasticity in the longitudinal direction as shown in the drawing, for example, rubber so as to expand and contract to some extent in accordance with the opening and closing movements of both legs. It is not necessary to have.

  That is, the substantially central portion (reference numeral 2) in the longitudinal direction of the hip joint exercise assisting tool is a ball storage portion that can store a ball therein. The ball storage portion is configured to prevent the ball from falling when the ball is repeatedly sandwiched between both legs and the legs are opened repeatedly. The ball storage portion of the present embodiment is made of a belt-like member provided with fastening members (6a, 6b) at both ends, and can be wound around in accordance with the size of the ball to hold the ball. It is comprised so that.

  In FIG. 2, the lower band (portions 4, 8, 9), the band 7 branched from the upper band 3, and the band 3 of the part until branched are right-handed around the right leg. It is a band which becomes a leg or a left leg wound around the left leg. The right leg and the left leg are long enough to wrap and fix the left and right thighs (near the knee).

  The member indicated by reference numeral 4 (stretchable material) and the member indicated by reference numeral 8 (material that is difficult to expand and contract) are connected so as not to be separated from each other by sewing. The member shown by the code | symbol 7 is a raw material which is hard to expand / contract. A hook-and-loop fastener (B surface: loop surface) is provided on the surface that becomes the outside (upper side in the drawing) when wound around the leg, and serves as a fastening member. As long as the loop surface is attached to the outside, the entire member 7 may be formed of a hook-and-loop fastener. A member indicated by reference numeral 9 is a hook-and-loop fastener (A surface: hook surface), and is sewn and fixed on the member indicated by reference numeral 8.

  By fitting the surface fastener A surface of the member 9 to the surface fastener B surface of the member 7 on each of the left and right sides, each becomes an annular shape and can be wound around the thigh of one leg. As shown in the drawing, it is configured to be wound from the lower side of the thigh to the upper side and fixed on the upper surface of the thigh. This is because it was considered easier to attach and detach. In addition, by doing so, the part that is wound and joined (the part where the hook-and-loop fastener 7 and the hook-and-loop fastener 9 are combined) is located on the upper surface of the thigh, and the part located on the side becomes the member 8 having poor stretchability. This is because there is an advantage that it is difficult to come off when both legs are opened.

  The width (short direction) is not particularly limited, but it is a width that is not too thin and not too thick in consideration of the thickness of the leg of the user, the size of the ball sandwiched between them, and the like. This is because if the left leg and the right leg are too thin, they will bite into the thigh when wrapped, and if it is too thick, it will be difficult and tight to wind. Further, if the ball storage portion is too narrow, the ball may jump out. For example, if it is a middle-aged and elderly person with general exercise | movement deficiency, the width | variety of the hip joint exercise assistance tool 1 has the preferable about 7 cm thru | or 15 cm.

  As described above, the hip joint exercise assisting device 1 includes a left leg portion wound around the left leg, a right leg portion wound around the right leg, and a space for storing a ball between the left leg portion and the right leg portion. A ball storage portion. The ball storage portion is made of a belt-like stretchable material provided with fastening members at both ends, and is configured to be wound in accordance with the size of the ball so as to hold the ball. The vicinity of the ball storage portion is made of a stretchable material that can open and close both legs appropriately. Each of the left leg portion and the right leg portion is configured so that it can be easily attached and detached.

  Near the center of the hip joint exercise assisting tool 1, that is, a region corresponding to a portion between the left leg and the right leg is made of an elastic material. The other regions are made of a material that hardly has stretchability. This makes it possible to stretch the hip joint appropriately by holding the ball between both legs while sitting, repeatedly opening and closing the legs, suppressing muscle weakness, and excessively open legs. Can be suppressed.

  Although it is possible to configure the entire hip joint exercise assisting tool 1 from an elastic material, when it is attempted to open both legs, the entire leg stretches and the force for suppressing the opening leg is weakened. For this reason, it is preferable that the elastic material is used only in the vicinity of the central portion, that is, around the portion between both legs.

Next, how to use the hip joint exercise assisting tool 1 of the present invention will be described.
When wearing (wrapping) the hip joint exercise assisting device 1, sit shallowly on the chair, and one of the lower leg portions (portions 4 and 8) of the hip joint exercise assist device 1 is under the thigh of one leg. And the other leg is placed under the thigh of the other leg so that the center C is substantially at the center of both legs, and the hook-and-loop fasteners 9 of the left leg and the right leg are placed on the hook-and-loop fastener 7. Fix them together and fix them lightly. Thereafter, the ball is placed in the center, the belt 3 that becomes the ball storage portion 2 is wound around the ball, and the ball is fixed by the hook-and-loop fasteners 6a and 6b. If possible, the position should be adjusted so that the thickest part of the ball hits the inside of the knees of both legs and thighs. Then, the hook-and-loop fastener 9 is firmly fixed to the hook-and-loop fastener 7 so that the position of the holding state is just right. Thereby, it is wound and fixed to each of the left leg thigh and the right leg thigh.
As the order of wearing, in the above description, it is wound around the ball after being wound around the leg, but it may be wound around the leg after being wound around the ball. Regardless of the order, the left leg and the right leg are each wrapped around the leg and fixed, and the ball is housed (wrapped) in the ball housing 2 so that it can be sandwiched between both legs (preferably near the knee). It only has to be.

  If you can wear the hip joint exercise assisting tool 1 with the ball stored in the ball storage part 2, while wearing it, close both legs a little, hold the ball from both sides, wait for a few seconds, and open both legs a little, Repeat several times. That is, while wearing, appropriately move both legs to open and close slightly to the left and right. By doing so, the hip joint can be stretched appropriately, and muscle strength can be prevented from being lowered while the legs are restrained to some extent. The hip joint exercise assisting device 1 of the present invention includes the ball storage portion 2 and the portion between both legs is made of an elastic material, so that the legs can be moved lightly by slightly opening and closing both legs.

  When ending the wearing of the hip joint exercise assisting tool (when removing it), it is only necessary to remove the fitting (hook fastener) of each leg part and remove it from the leg. Further, the ball may be taken out from the ball storage unit. The removed hip joint exercise assisting tool 1 is made of a flexible and foldable material (cloth, rubber, etc.), so it can be folded compactly and is light and easy to carry.

(Second Embodiment)
A second embodiment for carrying out the present invention will be described with reference to FIGS. FIG. 3 is a schematic view of the hip joint exercise assisting device of the present embodiment wound around the thighs of the right leg and the left leg and the ball stored in the ball storage unit as viewed from the front (knee side). is there. FIG. 4 is a schematic perspective view seen obliquely from above with the hip joint exercise assisting tool of the present embodiment opened. FIG. 5 is a schematic top view of the hip joint exercise assisting device viewed from the upper side (front side), and FIG. 6 is a schematic bottom view viewed from the opposite side (lower side, back side) of FIG. FIG. 7 is a schematic front view. It is. 5 to 7, the two lines of the waveform indicate that the space between them is omitted. In FIG. 4, the area | region (code | symbol 2 thru | or 4) which attached | subjected the thin several line is comprised by the cloth (spandex etc.) in which the part included the elastic material, for example, rubber | gum, urethane, etc., It shows that it has stretchability in the longitudinal direction.

  As shown in FIG. 3 to FIG. 7, the hip joint exercise assisting tool 10 of the present embodiment is elongated and has a band shape (band shape) as a whole. A substantially central portion (reference numeral 2) in the longitudinal direction is a ball storage portion. The ball storage portion 2 is configured such that both end portions (reference numeral 5) are firmly fixed by, for example, can-stop sewing or pressure bonding in the short direction, and are annular when opened. Each of the two sides has a bifurcated structure (portions 3, 6, 7 on the upper side of the drawing and portions 4, 8, 9 on the lower side of the drawing). The hip joint exercise assisting tool 10 as a whole is composed of a flexible material such as a cloth so as to be freely wound.

  A substantially central portion (reference numeral 2) in the longitudinal direction of the hip joint exercise assisting tool 10 is a ball storage portion that can store a ball therein. The ball storage portion 2 is made of a material having elasticity in at least the longitudinal direction so that the ball can be stored. For example, it is made of a cloth such as rubber or a mesh bandage, a cloth containing urethane or the like. Thereby, even when a slightly larger ball is put inside, the ball storage portion 2 can be extended to store the ball. A material having elasticity in the short direction is more preferable because the ball can be easily stored even if it is slightly narrower than the diameter of the ball. Further, when the ball is not accommodated, it is not stretched, so that the structure is compact.

  It is preferable that the ball storage portion expands to a size that can store one large ball. In this case, the “large ball” is a relatively large ball as long as it is sandwiched between the thighs of both legs and is not burdened. Although it depends on the thickness and length of the user's thigh, for example, the diameter is about 10 to 20 cm, preferably around 20 cm. If it is too large, it will be more burdensome to open both legs and pinch the ball.

This embodiment is mainly different from the first embodiment in that the configuration of the ball storage portion is not a wrapping shape, but is a configuration in which both ends are fixed in advance and become annular when opened. Other configurations are the same as those in the first embodiment, and thus are omitted.
The usage is the same as in the first embodiment except that the ball is stored by expanding the ball storage when storing the ball.

(Third embodiment)
A third embodiment for carrying out the present invention will be described with reference to FIGS. FIG. 8 is a schematic view of the usage state in which the hip joint exercise assisting device 20 of the present embodiment is wound around the thighs of the right leg and the left leg and the ball is stored as viewed from the front (knee side). FIG. 9 is a schematic perspective view of the hip joint exercise assisting device 20 according to the present embodiment viewed obliquely from above with the state opened. In FIG. 9, the area | region (code | symbol 2 thru | or 4) which attached | subjected the thin some line is comprised by the cloth (spandex etc.) containing the elastic material, for example, rubber | gum, urethane, etc., at least, It shows that it has stretchability in the longitudinal direction.

  As shown in FIGS. 8 and 9, the hip joint exercise assisting device 20 according to the third embodiment is entirely configured in a band shape (band shape), and its substantially longitudinal center (reference numeral C) is in the short direction. For example, it is firmly fixed by being sewn or crimped, and both sides thereof are symmetrically divided into two forks (reference numerals 3, 6 and 7 on the upper side of the drawing, and reference numerals 4 and 8 on the lower side of the drawing). , 9). In each of the left and right portions, the first member indicated by reference numeral 3 on the upper side of the drawing and the second member indicated by reference numeral 4 on the lower side of the drawing are third at the position of reference numeral 5 so that the ball can be accommodated therein. The member 11 is sewn and connected.

  The first member 3, the second member 4, and the third member 11 are all made of a stretchable material having flexibility such as a cloth such as rubber, a mesh bandage, or a cloth containing urethane. However, these are not necessarily the same material, and a stretchable material suitable for each location can be appropriately selected. When expanded as shown in the figure, a substantially annular space is formed, and the ball can be accommodated therein. Removing the ball makes it compact.

  That is, the hip joint exercise assisting tool of the third embodiment is elongated and band-like (band-like) as a whole, as in the first and second embodiments, and the substantially central part in the longitudinal direction is the ball storage part. However, the ball storage portion is divided into two parts on the left and right. The ball storage portion of the present embodiment is composed of the first member 3 at the upper end, the second member 4 at the lower end, and the third member 11 at the left and right ends, and each member is stretchable at least in the longitudinal direction. have.

  As shown in the drawing, the balls that can be stored in the third embodiment are arranged one by one on the right and left, and two in total, so they are smaller than the balls of the first embodiment, and the size is For example, one fist or the size of a tennis ball, that is, a diameter of about 5 cm to 10 cm. This is because if it is too large, it will be difficult to place two pieces side by side between both legs (both knees). If it is about a table tennis ball or smaller, it is too small to be suitable for exercises that are sandwiched between both legs.

In the third embodiment, since the size of the ball to be stored is about several centimeters in diameter, the width (length in the short direction) of the hip joint exercise aid 20 may be about several centimeters. That is, the hip joint exercise assisting device of the present embodiment is narrower than that of the first and second embodiments that are assumed to accommodate relatively large balls (about 15 to 25 cm in diameter). It is possible.
Since other points are the same as those in the first and second embodiments, description thereof will be omitted. The method of use is the same as that of the first embodiment except that the balls are stored one by one on the left and right, and the description thereof will be omitted.

Since the hip joint exercise assisting device of the present invention adopts the configuration as described above, it can easily perform hip joint stretching exercise and suppress excessive leg opening. That is, according to the present invention, it is possible to assist the hip joint stretching exercise in which a ball is sandwiched between both knees and force is applied to the inside so as not to be dropped and both legs are opened repeatedly. Excessive leg opening can be suppressed.
Even in a living environment where sitting time is long and back pain is likely to occur, repeated opening and closing movements of both legs can prevent posture deterioration and contribute to prevention of back pain. By making it possible to exercise the hip joints appropriately at home, it is possible to contribute to the maintenance of the health of middle-aged and elderly people who lack exercise, especially the elderly.

In addition, instead of wrapping around the thighs of both legs including the ball as a whole, the part between the legs (the part connecting the left leg part and the right leg part) is sewn and firmly fixed. The left leg thigh and the right leg thigh can be wound separately, so that a better fit can be felt.
In addition, by using stretchable material for the part between both legs and using material with poor stretchability for the other parts, while opening and closing both legs while sitting down, it is moderately appropriate It can be exercised and muscular weakness can be suppressed.

The above configuration is an example, and the present invention is not limited to the above configuration. The present invention can be freely configured without departing from the spirit of the present invention.
For example, depending on the thickness, thickness, and length of the user's thighs, the width and length of the member and finish may be inappropriate for the above width and length. An appropriate width and length can be selected depending on the situation without departing from the spirit of the invention.
Moreover, about the member which has a stretching property, also about the member which hardly has a stretching property, a raw material can be suitably selected from a commercially available thing so that the objective may be met.
As for the connection fixing method, in the above description, the cloth is used as the material, so that the connection is fixed. However, depending on the material, the connection fixing may be performed by thermocompression bonding.
