Description of the Related Art Conventionally, a strength training chair has been known as an instrument that allows elderly people, rehabilitation trainers, and the like to increase their strength indoors such as at home or in a facility (for example, Patent Document 1). In the chair of Patent Document 1, a plurality of rubber tubes (rubber bands are also possible) that fix the muscles of the upper limbs, the lower limbs, and the trunk muscles are fixed to a predetermined position of the body of the chair so as not to be detached. .
At the time of training, the user trains the upper limbs, the lower limbs, or the trunk by stretching or loosening the rubber tubes for the upper limbs, the lower limbs, or the trunk against the elastic force of each rubber. Thus, each part of the body can be trained comprehensively using a single chair.
JP 2005-334602 A

However, in the chair of Patent Document 1, a large number of long rubber tubes are connected to the chair main body so as not to be detached so that the upper limbs and lower limbs of the user can be trained with one chair in this way. For this reason, the adjacent rubber tubes are entangled and difficult to use, and a rubber tube that is not used has to be always provided in the chair body, and the cost is increased by the number of rubber tubes used.
An object of the present invention is to provide a training chair that can be used in a simple manner, trains a plurality of muscles with a single chair, prevents entanglement between elastic bands, and reduces costs. Yes.

According to the first aspect of the present invention, there is provided a string-like or belt-like elastic band in which a handle having both ends of a connecting belt fixed to both ends in the axial direction of a rod-shaped or cylindrical grip is connected to at least one end thereof. A training chair used for muscle training, having a chair body in which a seat supported by legs is connected to a backrest, and each surface of the front, back and both sides of the chair body A plurality of screw holes are provided at different positions in the vertical direction and the horizontal direction, and a locking projection is attached by screwing a bolt into these screw holes. almost a post of the same or polyhedron having it longer length, is formed at the distal end of the strut, for training a flange for hooking the elastic bands or the grip It is a child.

According to the first aspect of the present invention, after the elastic band is hooked on the predetermined hooking projection, the elastic band is trained on the body while the user is sitting on the chair, standing near the chair or sitting, for example. Hang on the part you want (arms, legs, etc.). Next, the elastic band is stretched or loosened against the elastic force of the elastic band. Thereby, desired muscles can be trained.
When it is desired to change the muscle to be trained, the elastic band is removed from the latching projection, and the newly selected muscle is latched on the latching projection. Thereafter, for example, the user sits on a chair and similarly stretches or loosens the elastic band against the elastic force of the elastic band to train the newly selected muscle.

  Thus, using one chair, each part of the body can be trained comprehensively with a simple method of use. In addition, it is possible to eliminate the entanglement between adjacent elastic bands, which has frequently occurred in the past. Furthermore, the unnecessary elastic band does not need to be always provided in the training chair as in the prior art. For example, when training different parts of the body, it is possible to use the same elastic band. In this case, the number of elastic bands used can be reduced and the cost can be reduced.

The training chair can be used to increase the muscular strength of, for example, elderly people, rehabilitation trainees, and people who want to train their bodies.
The body part (muscle group) trained by the training chair is arbitrary. Examples include upper psoas muscle, iliac muscle, rectus abdominis muscle, external oblique muscle, internal oblique muscle, spine standing muscle, latissimus dorsi muscle, deltoid muscle, biceps and triceps. In addition, lower quadriceps, hamstrings, triceps, etc. can be mentioned.

The shape of the chair body is arbitrary. For example, a seating part may be provided on four leg parts, and a backrest part may be connected thereto. Moreover, the thing which does not have a backrest part and may not have a leg part may be sufficient.
As materials for the chair body, for example, various trees (cedar, bamboo, pine, cherry, paulownia, cocoons, etc.), various synthetic resins (polypropylene, ABS resin, polyethylene, polyvinyl chloride, polyetheretherketone, acrylic, ethylene) Vinyl acetate, methacrylic resin, polyurethane, epoxy resin, phenol resin, etc.), various metals (iron, steel, aluminum, bronze, brass, nickel, these alloys, etc.), various ceramics (including tourmaline) are used. be able to.
The exposed surface of the chair body may be a surface of the chair body that is exposed to the outside. For example, the outer surface of a leg part may be sufficient and an inner surface may be sufficient.

The elastic band is freely bendable and can be elastically deformed when an external force is applied. For example, the string (for example, width 1-50 mm) with the intensity | strength and length which can perform muscle training of the desired part of a body may be sufficient, and a belt | band | zone (for example, width 50-300 mm) may be sufficient.
The material of the elastic band is arbitrary. For example, elastic materials such as various natural rubbers, synthetic rubbers, thermoplastic elastomers, and styrene butadiene elastomers can be employed.
A suitable elastic band is, for example, a ceraband manufactured by The Hygienic Corporation. Ceraband is configured to have different intensities depending on its color (yellow (-1), red (0), green (+1), blue (+2), black (+3), silver (+4), gold (+5)). Yes (from yellow to gold, the strength in parentheses is the contrast value).
The strength and length of the elastic band are appropriately selected depending on the physical strength of the user, the part where the body is trained, and the like.
The number of elastic bands used may be one or plural.

  The material of the latching protrusion is arbitrary. For example, any of those listed as materials for the chair body can be adopted.
  The attachment position of the latching protrusion to the chair body is arbitrary. Further, the number of the hooking protrusions attached to the chair body is arbitrary as long as it is two or more. Each latching protrusion may be separated from each other or may be close to each other.

The latching protrusion is attached by a screwed structure with bolts and nuts.

According to the first aspect of the present invention, when the elastic band is hooked to the hooking protrusion (hereinafter, when the band is hooked), for example, the grip is applied to the support column and the handle is hooked to the hooking protrusion. The elastic band can be indirectly hooked on the hooking protrusion. At this time, the support column is a polyhedron. Therefore, the rod-shaped or cylindrical grip has its peripheral side surface pressed against one side surface of the column by line contact. Therefore, the stability of the elastic band at the time of training is higher than when the column is cylindrical or cylindrical (the column and the grip are in point contact).

The material of the grip is arbitrary. For example, any of those listed as materials for the chair body can be adopted.
The grip may be rod-shaped or cylindrical.
The material of the connecting belt is arbitrary. For example, it may be a fabric (woven fabric, nonwoven fabric, knitted fabric), various soft synthetic resins, or various metals. The connecting belt may be changed to a linear member such as a wire or a rope.

Only one handle may be connected to only one end of the elastic band, or one handle may be connected to each end of the elastic band.
The polyhedron refers to a three-dimensional structure including a large number of surfaces, such as a triangular prism, a rectangular parallelepiped (including a cube), a pentagonal prism, a hexagonal prism, and an octagonal prism.
The length of the support column is approximately the same as or longer than the grip diameter. The length of the support column is such that the grip can be inserted between the chair body and the flange. It means that there is.
The flange may be formed directly on the tip of the column. Further, for example, the outer peripheral portion of a disc fixed to the tip end portion of the support and having a diameter larger than the diameter of the support may be used as the flange.
An elastic band or a grip may be hooked on the flange according to the user's choice.

According to a second aspect of the present invention, the front legs and the rear legs of the leg portions are respectively provided upright at both ends in the length direction of a pair of parallel connection frame frames installed on the floor. 2. The training according to claim 1, wherein a footrest having the hooking projections disposed on both side surfaces of the front end portion and a rubber non-slip sheet disposed on the lower surface is horizontally mounted on the front end portion of the front end portion. It is a chair.

  According to the first aspect of the present invention, since the elastic band is hooked to the plurality of hooking protrusions disposed on the exposed surface of the chair body, one chair is used, and simple Each part of the body can be trained comprehensively with usage. In addition, it is possible to eliminate the entanglement between adjacent elastic bands, which has frequently occurred in the past. Furthermore, the unnecessary elastic band does not need to be always provided in the training chair, and the same elastic band can be reused when training different parts of the body. As a result, the number of elastic bands used can be reduced and the cost can be reduced.

In addition, a handle having a rod-shaped or cylindrical grip is connected to at least one end of the elastic band, the length of the hooking protrusion is approximately the same as or longer than the diameter of the grip, and a flange is attached to the tip of the column. Since it is configured to be provided, when the band is hooked, for example, the grip can be applied to the support of the polyhedron, the handle can be hooked on the hooking protrusion, and the elastic band can be hooked indirectly on the hooking protrusion. Thereby, a grip and a support | pillar will be in a line contact state, for example, compared with the case where a support | pillar is a column shape or a cylindrical shape, stability of the elastic band at the time of training can be improved.

  Examples of the present invention will be specifically described below.

  1 to 3, reference numeral 10 denotes a training chair according to Embodiment 1 of the present invention. The training chair 10 includes a chair body 11, an elastic band 12 having a strip shape for muscle training, and an exposed surface of the chair body 11. And a plurality of latching protrusions 13 capable of latching the elastic band 12.

  The chair body 11 has a height of 140 cm and includes a leg portion 14, a seating portion 15, and a backrest portion 16. Specifically, a front leg 18 and a rear leg 19 are erected on both ends in the length direction of a pair of parallel connecting frame 17 installed on the floor. A rubber anti-slip sheet 17 a is attached to the lower surfaces of the two connecting stand frames 17. A rectangular footrest 20 in a plan view is horizontally mounted on the front end portions of the two connecting platform frames 17. Leg frames 20a are disposed on the lower surfaces of both sides of the footrest 20, and rubber anti-slip sheets 20b are adhered to the lower surfaces of both leg frames 20a. On both side surfaces of the front end portion of the footrest 20, latching protrusions 13 are provided. Instead of the footrest 20, a tread board (not shown) may be employed. A plurality of treads may be stacked so that the height can be adjusted. Both rear legs 19 are approximately twice as long as the front legs 18. The upper portions of both rear legs 19 form a pair of backrest side frames 21 that constitute a part of the backrest portion 16. The lower ends of the left and right front legs 18 are connected by a beam frame 22 for reinforcement. Similarly, the lower ends of the left and right rear legs 19 are also connected by another beam frame 22.

On the left and right sides of the chair, the upper end of the front leg 18 and the intermediate position in the height direction of the rear leg 19 are connected to each other by a horizontal armrest plate 28 constituting a part of the seating portion 15. In addition, on the left and right sides of the chair, the front legs 18 and the rear legs 19 are respectively reinforced by the side beam frames 23 at a height position of approximately two-thirds of the front legs 18. Further, between the four front legs 18 and the rear legs 19, a rectangular seating plate 24 is fixed in a horizontal state at a height position of approximately two thirds of the front legs 18 in a plan view.
An upper beam frame 25 is laid across the upper ends of the backrest side frames 21. A pair of upper and lower waist pads 26 that are gradually inclined rearward toward the upper side are horizontally mounted below the backrest side frames 21. A beam bar 27 is horizontally mounted at a position slightly above the waist pad 26 of the backrest side frames 21.

Further, the front legs 18, the rear legs 19, the backrest side frames 21, the two beam frames 22, the two beam frames 23, the upper beam frames 25, the upper waist plate 26 and the both armrest plates 28 are respectively provided at predetermined positions. In addition, a number of screw holes 29 for attaching the latching protrusions 13 are provided (FIG. 1).
The specific positions where the screw holes 29 are formed will be described. In the case of the front legs 18, the rear legs 19, and the backrest side frames 21, there are three locations, an upper portion, an intermediate portion, and a lower portion. Further, in the case of the two beam frames 22, the two beam frames 23, the upper beam frame 25, and the upper waist plate 26, there are two locations at both ends in the length direction. Furthermore, in the case of both armrest plates 28, it is the tip.

As the elastic band 12, a yellow sera band (a predetermined thickness, a width of 14 cm, a length of 2 m, and an intensity value of −1) manufactured by The Hygienic Corporation is employed (FIG. 3). The elastic band 12 is used by being hooked or gripped on the latching protrusion 13.
Handles 30 are detachably connected to both ends of the elastic band 12, respectively. The handle 30 is a thick non-woven fabric that is attached to both ends in the axial direction of the grip 31 and is connected to the elastic band 12 via the buckle 32 by a thick cylindrical grip (grip handle) 31 made of synthetic resin. And a short connecting belt 33 made of The handle 30 may be used by gripping the grip 31 or may be used by hooking the grip 31 on the latching protrusion 13. The buckle 32 employs a known structure capable of adjusting the length of the hooked elastic band 12.

Next, each latching protrusion 13 is demonstrated with reference to FIG.
The latching protrusion 13 has a column 34 having a rectangular cross section (polyhedron) perpendicular to the length direction, and a thick latching disc 35 in which the center of the back side is fixed to the tip of the column 34. (FIG. 4A). The length of the column 34 is slightly longer than the diameter of the grip 31. Further, the diameter of the retaining disk 35 is slightly longer than the width of the support column 34 (long rectangular side). As a result, a portion of the hooking disc 35 that protrudes in an annular shape from a portion connected to the column 34 forms a flange on which the elastic band 12 is hooked directly or the grip 31 is hooked. Instead of the column 34 having a rectangular cross section, a column 34A having a hexagonal cross section may be used (FIG. 4B), or a column 34B having an octagonal cross section may be used (FIG. 4C). Each strut 34 has a corresponding strut 34 in a direction substantially perpendicular to the pulling direction of the elastic band 12 so that the stability of the grip 31 applied to the latching protrusion 13 selected according to each training event is enhanced. You may comprise so that the length direction of the elongate side may be arrange | equalized (FIG. 5 and FIG. 6).

Each latching protrusion 13 is formed with a screw insertion hole 13 a penetrating through both end surfaces in the length direction of the column 34 along the axis of the latching disk 35. Here, a total of 28 latching protrusions 13 are used, and each latching protrusion 13 passes a bolt 36 through the screw insertion hole 13a, and screwes the tip of the bolt 36 into a predetermined screw hole 29. Thus, it is detachably fixed to the chair body 11. The structure for changing the mounting position of the latching protrusion 13 is constituted by the screw insertion hole 13 a, the screw hole 29, and the bolt 36.
The mounting positions of the latching protrusions 13 are as follows: the lower outer surfaces of the front legs 18, the lower outer surfaces of the rear legs 19, the intermediate outer surface and the upper outer surface of the backrest side frames 21, and both beams They are the outer surface of the both ends of each length direction of the frame 22, the both side beam frame 23, the upper beam frame 25, and the upper waist plate 26. However, in the case of the rear beam frame 22, the inner surface of the rear beam frame 22 is slightly positioned at the intermediate position in the length direction of the beam frame 22 slightly from the attachment position of the latching protrusions 13. A pair of latching protrusions 13 are attached.

  Next, a method for using the training chair 10 according to the first embodiment of the present invention will be described with reference to FIGS. Here, a knee lift exercise (FIG. 5), which is a kind of upper body strengthening exercise performed by a user such as an elderly person sitting on the seat 15, and a leg extension exercise (FIG. 6), which is a kind of lower body strengthening exercise. Will be explained. In addition, the rowing exercise (FIG. 7), the abdominal exercise (FIGS. 8 and 9), and the pull-down exercise (FIGS. 10 and 11) will be described.

  As shown in FIG. 5, in the knee lift movement, the grips 31 of the handles 30 are respectively applied to the lower surfaces of the columns 34 at the pair of hooking projections 13 disposed on the front beam frame 22, and the handles 30 are moved. It latches to the corresponding latching protrusion 13 in a press-fit (insertion) state. As a result, the elastic band 12 is indirectly hooked to the hooking protrusions 13 via both the handles 30. At this time, since the column 34 is a rectangular parallelepiped with a rectangular cross section, the cylindrical grip 31 having a horizontal axis is pressed against one side of the column 34 by line contact. Therefore, the stability of the elastic band 12 at the time of training is increased compared to the case where the support column 34 is a latching protrusion 13 having a columnar shape or a cylindrical shape (the contact between the support column 34 and the grip 31).

  Thereafter, the user sits on the seating plate 24, pulls up the middle portion in the length direction of the elastic band 12, and inserts both closed thighs directly into the inner space of the elastic band 12. When the looseness of the elastic band 12 is large, the elastic band 12 is tightened using the buckle 32 until the elastic band 12 becomes about 70 cm, for example. Then, one leg (right leg in FIG. 5) is slowly lifted against the elastic force of the elastic band 12. When you reach the top position, take a breath (rest for a few seconds) and slowly drop your foot. Thereafter, the same exercise is performed on the other leg. Thereafter, 3 sets of 10 times each for the right foot and left foot are performed. By such knee lift exercise, mainly the iliopsoas muscle (general name of the psoas muscle and iliac muscle) and the quadriceps femoris can be strengthened. The iliopsoas muscle is a muscle that lifts the thighs, and is used to lift legs when climbing stairs or to rise during running. Training this makes it easier to go up and down the stairs.

Next, a method for performing the leg extension exercise will be described with reference to FIG.
First, the grips 31 of the two handles 30 are hooked on the pair of hooking protrusions 13 disposed at the lower portions of the front legs 18 in the same manner as in the knee lift movement. However, the axes of both grips 31 are in a vertical state. The length of the elastic band 12 after the length adjustment is 70 cm. Thereafter, a middle part in the length direction of the elastic band 12 is twisted to form a ring, and one foot tip is hooked here. Then sit deep in the chair and keep your back straight and your legs so that your knees won't leave your chair. Then take a breath and slowly return. Thereafter, the same exercise is performed on the other leg. Do this 3 times for 10 times each for the right and left foot. Such leg extension exercise mainly reinforces the quadriceps muscles, as well as the iliopsoas muscles. As a result, the burden on the knee during walking can be reduced and the stride can be widened.

Next, a method for performing a rowing exercise will be described with reference to FIG.
First, the intermediate portion in the length direction of the elastic band 12 (about 60 cm in length) is hooked over the pair of hooking protrusions 13 disposed on the inner surface of the rear beam frame 22. Thereafter, the user sits down on the floor behind the training chair 10, aligns both feet, and presses the sole against the surface of the intermediate portion in the length direction of the rear beam frame 22. In this state, the grips 31 of both the handles 30 are grasped, both sides are tightened, and both the handles 30 are slowly pulled so as to row the boat with both hands against the elastic force of the elastic band 12. At that time, stretch your chest and straighten your back. Then pull until the elbow reaches a position behind the back. Since this buttocks rub against the floor, it is preferable to perform this exercise with a mat or cushion. This is a set of 10 times, and 3 sets are performed. Such rowing exercises can mainly strengthen the latissimus dorsi muscle, as well as the deltoid, trapezius, and rhomboid muscles. As a result, the muscle weakness around the scapula and the lack of exercise can be resolved, and the back of the circle can be prevented and improved.

Next, a method for performing the abdominal motion will be described with reference to FIGS.
First, the intermediate portion in the length direction of the elastic band 12 adjusted to a length of 90 cm is hooked on the both hooking protrusions 13 of the upper waist plate 26. Then, both the handles 30 are arranged above the upper waist plate 26 and in front of the chair. Thereafter, the user seated on the seating plate 24 grips both grips 31 and holds them firmly while crossing both grips 31 in front of the chest (FIG. 8). After that, while rolling the back, the upper body is slowly tilted forward so as to look into the navel against the elastic force of the elastic band 12 (FIG. 9). When you reach the maximum tilt position, take a breath and slowly return. This exercise is also performed 3 times, with 10 times as one set. Such abdominal exercise mainly reinforces the rectus abdominis muscle, as well as the external abdominal oblique muscle, the internal abdominal oblique muscle, and the spinal column standing muscle. As a result, the abdominal pressure is increased, and the spine can be firmly supported from the inside, and a posture in which the abdominal muscles and the back muscles are balanced is less likely to cause back pain.

Next, a method for performing a pull-down exercise will be described with reference to FIGS. 10 and 11.
Here, auxiliary rods (length: 90 cm, diameter: 30 mm) 37 each having hooking projections 13 protruding at both ends in the axial direction are used (FIG. 10).
As shown in FIG. 11, the lengthwise intermediate portion of the elastic band 12 adjusted to a length of 90 cm is hooked to both the hooking protrusions 13 of the upper beam frame 25. Then, the grips 31 of both handles 30 are hooked on both hooking protrusions 13 of the auxiliary rod 37. As a result, the auxiliary rod 37 is held behind the backrest 16 with its axis line horizontal. Thereafter, the user sits down on the floor behind the training chair 10 with his back facing the backrest 16. Then, the both ends of the auxiliary rod 37 are grasped with the back hand, and the auxiliary rod 37 is slowly pulled down. When you reach the maximum lowering position, take a breath and slowly return. This exercise is performed 10 times, one set and three sets. By such a pull-down exercise, mainly the latissimus dorsi muscle, as well as the great circular muscle, the biceps brachii muscle, and the upper arm muscle can be strengthened. Thereby, the effect of preventing the back of the circle and maintaining the correct posture can be obtained.

Thus, using one training chair 10, each part of the body can be trained comprehensively with a simple method of use. In addition, it is possible to eliminate the entanglement between adjacent elastic bands, which has frequently occurred in the past. Further, the unnecessary elastic band 12 does not need to be always provided in the training chair as in the prior art. For example, when training different parts of the body, the same elastic band 12 can be used. Thereby, the usage number of the elastic band 12 can be reduced and cost reduction can be aimed at.
Moreover, in Example 1, the connection position of the latching protrusion 13 on the chair main body 11 can be changed easily by changing the screw hole 29 to which the latching protrusion 13 is attached. As a result, muscles existing in other parts of the body can be trained.
