Description

  The present invention relates to a strength training tool for training a back strength and abdominal strength to make a healthy body, and more particularly to a back strength training tool mainly for training the back strength effectively even by elderly people with minimal exercise.

  In order to prevent lifestyle-related diseases and lead a healthy life, consideration for diet and appropriate exercise are necessary, but maintaining a certain level of muscle strength according to age is also important. For middle-aged and older people, weakening of the trunk muscles such as the abdominal muscles and back muscles not only causes internal strain and nerve burden due to worsening posture, but also slows down all life movements and promotes deterioration of physical functions due to aging Cause. In particular, the back muscles are the most important muscles in basic daily activities such as posture maintenance, up and down stairs, and lifting and lowering things, and their continuous training is necessary to maintain a healthy life for the elderly. Is desirable.

Therefore, various exercise methods and exercise equipment have been proposed for the purpose of creating a healthy body. For example, an abdominal muscle exercise assisting tool that can be used in the bed described in Patent Document 1, a back muscle strength training tool described in Patent Document 2, a sitting chair type training device described in Patent Document 3, an abdominal muscle table described in Patent Document 4, There are exercise equipment, exercise equipment having a plurality of functions described in Patent Document 6, training equipment described in Patent Document 7, abdominal muscle exercise equipment described in Patent Document 8, health equipment described in Patent Document 9, and a bed.

  However, many of these prior arts mainly focus on the support of abdominal exercises, mainly because of emphasizing a cosmetic viewpoint such as maintaining and improving body shape, and training of the back muscles is an incidental position. Tend. Patent Document 2 and Patent Document 8 disclose usage methods for back muscle movement, both of which fix the user's ankle, specifically, the vicinity of the Achilles tendon. Moreover, the form which exercise | moves in the state which the tip was not fixed especially from the ankle or the toe was forcibly extended is taken. In addition, the back muscle exercise method described in Patent Document 2 has an extremely large stroke of the reciprocation of the upper body, which is an exercise with a considerable burden on the elderly.

The so-called back muscles refer to multiple muscles along the spine of the back, collectively called the spine upright muscles. Nervous. At this time, compared to the case where the tip of the ankle is left in the released state, the case where the anterior tibial muscle is contracted along the so-called opposite shin by attracting the tip of the foot toward the shin direction extends from the leg to the buttocks. The tension on the back increases, and the lower back, which is the fulcrum of the back movement, stabilizes. As a result, even if the stroke of the reciprocating motion of the upper body is small, the load on the spinal column standing muscle becomes large, and the efficiency of the back muscles increases.

Also, during back muscle exercise, it is necessary to prevent the lower body, particularly the legs, from jumping upward in balance with the weight of the upper body, and the ankle portion is generally fixed in some form. Here, in order to prevent the ankle part from jumping upward, it is sufficient to hold the heel part from above, but if the Achilles tendon is fixed as in the prior art, the toe is directed toward the shin as described above. It becomes difficult to attract.

  The present invention has been made in order to address the above-mentioned problems, and does not fix the Achilles tendon during back muscle movement, but by tensioning the tip of the foot toward the shin direction, the stroke of the reciprocating movement of the upper body It is possible to apply an effective load to the spine standing muscle without increasing the size, and as a result, it is possible to train the spine efficiently with a short exercise even for elderly people with poor muscle strength in the first place. The purpose is to provide a back strength training tool.

  Further, the present invention can be used not only for the back muscle exercise but also for the abdominal muscle exercise as it is, and the predetermined part can be appropriately adjusted according to the height, body shape and size of the foot of the user. Accordingly, it is an object of the present invention to provide a simple and low-cost back strength training tool that anyone can use with an optimal setting.

In order to solve the above-mentioned problem, the spine strength training tool according to claim 1 is a spine strength training tool including a bench part and a leg fixing part attached to one end of the bench part via a support girder. The leg fixing part includes a substrate, an instep holding part, a heel holding part, and a side plate.

When the user exercises the back muscles, the user becomes hungry on the bench portion, and uses both ankles inserted into the leg fixing portion. In the leg fixing part, both soles are brought into close contact with the substrate, and the both insteps are held by the instep holding part, while the both toes are pressed by the heel holding part, and the outer sides of both legs, specifically, the little finger Press the outer surface near the base against the side plate. The heel holding part comes into contact with the back of both footpads, but the Achilles tendon is not fixed. As a result, the user's feet are fixed so as not to be displaced in any of the front, rear, left, right and up directions by the three points of the instep, the heel and the little finger base.
In this state, the user strokes the upper body up and down with the waist as a fulcrum, and at this time, the both insteps are strongly pressed against the instep holding part by attracting both toes in the shin direction. The anterior tibialis muscle, rectus femoris muscle, and greater gluteal muscle are integrally tensioned and the lower body is fixed, so that the spine standing muscle is effectively trained.

During abdominal exercise, the user lies on his back on the bench, and uses both feet inserted in the gap between the heel holding part and the footrest plate attached to the upper surface of the support girder. When the soles of the feet are placed against the footrest plate, the heel holding portion fixes both insteps from above, and the user holds the feet so that they do not lift when performing abdominal exercises by stroking the upper body up and down.

  Next, the invention described in claim 2 is the spine strength training tool described in claim 1, wherein the leg fixing portion is configured such that the foot holding portion is at an arbitrary angle and distance with respect to the substrate. It is attached so that it can be fixed, and the hook holding part is attached so as to be fixed at an arbitrary position of the substrate.

  The instep holding part is held at a predetermined distance from the substrate surface by the side plate. The mounting part between the instep holding part and the side plate is provided with an adjustment mechanism capable of appropriately adjusting the angle and distance of the instep holding part with respect to the substrate surface, and the instep holding part according to the size and height of the user's foot To adjust the angle and position. The structure of the adjusting mechanism is arbitrary, but a structure that can be easily finely adjusted by the user and that does not loosen or shift inadvertently during exercise is desirable.

  On the other hand, the heel holding portion is held in a shape that rises in a vertical direction with respect to the substrate from the upper part of the substrate, and is provided with an adjustment mechanism that can move up and down on the substrate as it is. The position and angle can be adjusted accordingly. The structure of the adjusting mechanism is arbitrary, and a structure that can be easily fine-tuned by the user and that does not loosen or shift unintentionally during exercise is desirable.

  Next, the invention described in claim 3 is the spine strength training tool described in either claim 1 or claim 2, wherein the attachment part between the bench part and the support beam is a movable structure. Thus, the leg fixing portion can be fixed at an arbitrary distance from the bench portion.

  The support girder is attached to an appropriate location on the back of the seating surface at one end of the bench portion, and an adjustment mechanism is provided that can move back and forth in the longitudinal direction of the bench portion at the attachment location. Since the distance between the end of the bench part and the leg fixing part can be arbitrarily adjusted by moving the support beam back and forth, an optimal setting can be made as appropriate according to the height of the user and the leg length. The structure of the adjusting mechanism is arbitrary, and a structure that can be easily fine-tuned by the user and that does not loosen or shift unintentionally during exercise is desirable.

  Next, the invention described in claim 4 is the spine strength training tool according to any one of claims 1 to 3, wherein when the back muscles are exercised, the upper surface of the bench part and the abdomen of the user It further has a cushion used by being sandwiched between arbitrary positions in between, and the angle of the trunk axis of the user with respect to the bench top surface can be arbitrarily set.

  During back muscle exercise, when the user holds the cushion under the abdomen, the trunk axis of the lower body of the user takes an upward angle with respect to the upper surface of the bench, increasing the stroke of the upper body during exercise. Thus, the load on the back muscles can be appropriately strengthened. The elevation angle can be arbitrarily changed according to the position and thickness of the cushion, but is preferably around 7 degrees with respect to the bench top surface. During back muscle exercise, the user's body is supported at two points: the ankle fixed by the leg fixing part and the abdomen held by the cushion, so that both knees are on the bench top when the upper body is bent upward Do not touch.

  If the back muscle strength training tool of the present invention is the means described in the above claims, the upper body reciprocates by tensioning the toes toward the shin direction without fixing the Achilles tendon during back muscle movement. Even if the stroke is not increased, it is possible to apply an effective load to the spine standing muscle, and as a result, even the elderly with poor muscular strength can efficiently train the back muscles with a short exercise. It becomes possible. In addition, it can be used for abdominal muscle exercises as well as back muscle exercises, and it is possible to adjust the predetermined part according to the user's height, body shape, and foot size, so anyone can use the optimal setting. A simple and low-cost back strength training tool that can be used can be provided.

  Hereinafter, specific modes for carrying out the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of an embodiment of a back muscle strength training tool according to the present invention. This back strength training tool mainly includes a bench portion 10 and a leg fixing portion 20, and the bench portion 10 includes a seat surface portion 11 and a leg portion 12 with a soft pad on the upper surface. On the other hand, the leg fixing unit 20 includes a base plate 22, an instep holding unit 23, a heel holding unit 24, and two side plates 25 for fixing them, and the bench is interposed via a support girder 21 attached to the base plate 20. Connected to the unit 10. It is desirable that both the instep holding part 23 and the heel holding part 24 protect the foot by using a flexible member having elasticity on at least the surface that contacts the user's foot. On the other hand, the cushion 15 is an independent member and has a thickness of at least 70 mm. During back muscle exercise, the user's trunk axis is installed below the abdomen so that the elevation angle of about 7 degrees with respect to the seat surface portion 11 is used. In addition, the leg fixing | fixed part 20 is provided with the support leg 28 in which a lower end contacts a floor surface.

  FIG. 2 is an enlarged perspective view in which a connection portion between the bench portion 10 and the leg fixing portion 20 in FIG. 1 is enlarged, and an end portion of the bench portion 10 is a perspective view to show the structure of the connection portion. The support girder 21 to which the leg fixing part 20 is attached is connected to the bench part 10 by a support member 13 provided at the lower part of the seat surface part 11 while being held horizontally. The support member 13 has an adjustment mechanism 14 and can be fixed at an arbitrary position by horizontally moving the support beam 21 in the axial direction. With this mechanism, the distance between the end portion of the bench portion 10 and the leg fixing portion 20 can be freely adjusted within a certain range, and can be appropriately set according to the height of the user and the length of the foot.

The support beam 21 is bent upward in the middle toward the leg fixing portion 20 side. For this reason, the surface of the base plate 22 of the leg fixing portion 20, that is, the surface where the user's feet are in contact with each other during back movement is inclined leftward in the figure by the angle of bending with respect to the vertical direction. The horizontal movement by the adjusting mechanism 14 is limited to the horizontal portion between the end on the bench 10 side and the bending point. When the support girder 21 is connected and moved to the bench portion 10 while keeping the elevation angle without bending, the height of the leg fixing portion 20 from the ground is changed due to a change in the distance between the bench portion 10 and the leg fixing portion 20. Although the inconvenience that changes occurs, if the support girder 21 is moved horizontally by being bent and limited to the horizontal portion up to the bending point, the height of the leg fixing portion 20 is kept constant and the distance from the bench portion 10 is maintained. The above-mentioned inconvenience can be solved.

  FIG. 3 is a side view showing a state in which the back muscle strength training tool according to the present embodiment is used for back muscle exercise. The user becomes prone on the seat surface portion 11 of the bench portion 10 and inserts both ankles into the leg fixing portion 20 for use. In the leg fixing portion 20, both foot soles are brought into contact with the substrate 22, and the both insteps are pressed by the instep holding portion 23, while the both toes are pressed by the heel holding portion 24, and further, The entire ankle is fixed by pressing both little finger bases on the sides of both feet. Thereby, since a user's both feet are fixed in three places, an instep, a heel, and a little finger base, it does not shift | deviate in any direction of front-back, left-right, up-down. The instep holding part 23 and the heel holding part 24 are attached to the side plates 25 via an adjusting mechanism 26 and an adjusting mechanism 27, respectively. By the adjustment mechanism 26, the instep holding part 23 can be held and fixed with respect to the substrate 22 at an arbitrary angle and distance. Further, the collar holding portion 24 can be held and fixed to the substrate 22 at an arbitrary position by the adjusting mechanism 27. As described above, both ankles can be appropriately held according to the size of the user's foot, the height of the foot, the shape of the heel, and the Achilles tendon of the user is not fixed. During back muscle exercise, the user adjusts the fixing position of the support girder 21 so that his / her knees are positioned slightly outward from the end of the seating surface portion 11 on the leg fixing portion 20 side. When both knees are on the seating surface portion 11, when the upper body is bent upward, a large load is prevented from being applied in the opposite direction to bending the knees at both knee joints.

The user performs back muscle movement by stroking the upper body up and down using the waist as a fulcrum. At this time, because both ankles are held without fixing the Achilles tendon by the above structure,
When the upper body is bent upward and a load is applied to the back muscle, the user pulls both toes in the shin direction and strongly presses them against the instep holding portion 23. This operation contracts the user's front tibialis and rectus femoris, and further contracts the greater gluteal muscle, so that the entire lower body is tensioned and fixed together. As a result, the spine standing muscle extending from the waist to the neck is effectively trained. In the conventional spine training tool, the Achilles tendon is fixed, but both the toes are in a released state. Therefore, the user does not actively try to attract both toes in the shin direction. For this reason, the anterior tibialis and rectus femoris were not fully tensed, and mainly the greater ankle muscles were tightened, so to speak, using the muscles "just above the hips", the back muscles were exercised. According to the spine strength training tool according to the present invention, as described above, the spine standing muscles are trained while interlocking the muscles of the entire lower body during the spine exercise, so that more effective spine exercises can be performed. Even users who lack back strength can expect a certain effect with limited exercise.

  Further, the figure shows a state in which the cushion 15 is sandwiched between the seat surface portion 11 and the user's abdomen to perform back muscle exercise. By sandwiching the cushion 15 at an appropriate position, the angle of the trunk axis in the lower body of the user with respect to the seat surface portion 11 can be arbitrarily set. Thereby, the stroke of flexion and extension of the upper body during back muscle exercise can be adjusted, and the load on the spine standing muscle can be adjusted. The cushion 15 has an elevation angle of about 7 degrees with respect to the horizontal of the user's trunk, and when the user stretches the spine in that state, the user's chest is separated from the seat surface 11 by about 15 cm, It is preferable to install and use at a position where the whole body is supported by two points, the foot and the abdomen.

FIG. 4 is a plan view of a state in which the back muscle strength training tool according to the present embodiment is used for back muscle movement as viewed from above.

FIG. 5 is a side view showing a state in which the back muscle strength training tool according to the present embodiment is used for abdominal muscle exercise. The user lies on his back on the seat surface portion 11 and places both feet on the upper surface of the support beam 21. As a result, the portion from both insteps to the ankle is fixed in close contact with the lower surface of the heel holding part 24, so that the user can bend the upper body with the waist up as a fulcrum while keeping the knees up. Do. Since the heel holding portion 24 is attached to the inner surface of the side plate 25 through the adjusting mechanism 27 as described above, the user uses the adjusting mechanism 27 to adjust the heel holding portion 24 according to the height of his / her instep. You can adjust the position and fix the toes appropriately.

The back muscle strength training tool according to this embodiment can also be used for training of the pectoral muscles and upper arm muscles using dumbbells as shown in FIG. As shown in FIG. 1 and FIG. 4, the width of the portion near the head of the seating surface portion 11 is reduced because of the conflict between the user's shoulder and upper arm portion and the seating surface portion 11 when used for such dumbbell movement. This is to alleviate.

In the above embodiment, it is appropriate to use a steel material having excellent strength and durability as the main structural material of the bench portion 10, the leg fixing portion 20, and the support beam 21 connecting them. In order to implement a back strength training tool for households at low cost, wood can be used as a material. Depending on the physique of the user, the force with which the leg fixing unit 20 is lifted upward during use increases, and the structural load on the support member 13 and the adjustment mechanism 14 that connect the support beam 21 and the bench unit 10 is increased. In the case where there is a possibility of overloading, a weight 29 that can be attached / detached and replaced with an appropriate weight may be attached to the leg fixing portion 20 as shown in FIG.

As described above, the configuration and use state of the embodiment of the spine strength training tool according to the present invention have been described in detail. However, the present invention is not limited to the above embodiment, and the scope of the technical idea of the present invention. Can be improved or modified within the scope of the present invention.

  The present invention can provide a spine strength training tool that can easily train the back muscles and abdominal muscles with a simple and low-cost structure. In particular, during back muscle exercise, by tensioning the toes toward the shin direction, an effective load can be applied to the spine standing muscle without increasing the stroke of the reciprocating movement of the upper body. In addition, even an elderly person who has poor muscle strength in the first place can efficiently train the back muscles with a short exercise.
