Description

[Detailed Description of the Invention] The present invention relates to an improvement of an auxiliary device used during extension and flexibility exercises.

Stretching and flexibility exercise refers to stretching the muscles and tendons of various parts of the body by gradually applying reasonable force to them, thereby removing tension from the muscles and tendons, massaging them, and making them flexible. It is a purposeful exercise, and is commonly referred to today as stretching exercises. This stretching exercise is
If you do this as a warm-up exercise before playing sports, you can prevent accidental injuries such as strained muscles during sports, and if you do it as a refreshing exercise after finishing sports, it will calm down the excitement of the muscles and tendons that have been overworked during sports and quickly relieve fatigue. It has the effect of removing
In addition, this stretching exercise is supported by health and physical education theory that it increases the flexibility of the body, maintains youth and health, and is even useful for beauty. In recent years, it has become popular not only in the sports world but also in general.

The present invention was devised to further enhance the effects of such extension and flexibility exercises, and is particularly useful for exercises that stretch the Achilles tendon and calves. It is an object of the present invention to provide an auxiliary device for extension and flexibility exercise that can perform flexible exercises and diversify flexibility exercises.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows an auxiliary device for extension and flexibility exercise (hereinafter simply referred to as the auxiliary device) 10 according to the present invention. This auxiliary tool 10 includes a support stand 20 that is placed directly on the floor or the like, a step stool 30 assembled to this support stand 20, an angle adjustment member 40 that is inserted between the support stand 20 and the step stand 30, and a support stand. A stopper 50 provided at the rear of the footrest 20 and a semicylindrical member 60 attached to the step stool 30 are provided.

The support stand 20 has a size sufficient to hold the step stool 30 on which a person stands, and in this embodiment, the support stand 20 and the stopper 50 are integrally formed. Further, as shown in FIG.
A recess 21 for storing the angle adjusting member 40 is provided on both left and right sides of the recess 21.
A toothed portion 22 is formed in which the teeth 2 engage with each other. Each of these teeth 22 is connected to the front part of the support base 20 (stopper 5
0), and as shown in FIG. 3, it has a sawtooth shape with the front side facing the vertical surface 22a. Furthermore, each of these tooth portions 22
A guide groove 23 for guiding the protrusion 41 of the angle adjusting member 40 is formed on the support base 20 located on the outside of the support base 20 .

The step stool 30 has a size that allows a person to stand on it, and has a non-slip pattern on its upper surface. Further, on the upper surface of this step 30, guide grooves 31 and 3 are provided vertically (in a direction perpendicular to the stopper 50) and laterally (in a direction parallel to the stopper 50).
2 is formed. These guide grooves 31 and 32 in this embodiment, as shown in FIG. 5, for example, are designed so that they can be dovetail-grooved to an engaging portion 61 formed on the lower surface of a semicylindrical member 60. It holds the mold member 60 in a detachable manner. Further, at the rear end of this step stool 30, a fourth
As shown in the figure and FIG. 5, protrusions 33, 33 are formed. These protrusions 33, 33 are fitted into engagement holes 51, 51 of a stopper 50, which will be described later, and as shown in FIG. The upper surface thereof is formed into a circular arc surface 35 centered on a fulcrum 34. Furthermore, a recess 36 corresponding to the recess 21 of the support base 20 is formed on the lower surface of the center of the step stool 30, and this recess 36 and the recess 21 of the support base 20 support the step stool 30. The size is such that the angle adjustment member 40 can be reliably accommodated when it is brought into close contact with the table 20. The angle adjustment member 40 has a thickness that is strong enough to support the weight of a person, and its top 43 is cut into an acute angle, as shown in FIG.

The stopper 50, which is integral with the support stand 20, stands upright at the rear end of the support stand 20, and has an engagement hole 5 at the lower front thereof as shown in FIGS. 2 and 6.
1,51 are formed. As shown in FIG. 6, the upper part of each engagement hole 51 is an arcuate curved surface 52, and this curved surface 52 corresponds to the arcuate surface 35 of the protrusion 33 on the step stool 30. Further, a cushioning material 53 is attached to the upper front surface of the stopper 50.

As shown in FIG. 6, the semicylindrical member 60 is a semicylindrical member having a curved surface 62 corresponding to the arch of a human foot, and a large number of small protrusions 63 to 63 are formed on the curved surface 62. There is. This semi-cylindrical member 60 has an engaging portion 61 formed on its lower surface that is connected to the vertical or horizontal guide grooves 31 and 3 of the step stool 30.
By fitting into the step board 30, it can be attached to the step stool 30 in any direction.

The support tool 10 configured as described above is assembled in the following manner. That is, each projection 33 of the step stool 30 is fitted into each engagement hole 51 of the stopper 50. As a result, the step stool 30 will be attached to the support stand 20 side, but this step stool 30 will be attached to the support stand 20 side.
As shown in the figure, only rocking is possible in which the arcuate surface 35 of each protrusion 33 is in sliding contact with the curved surface 52 of the engagement hole 51 about the fulcrum 34 of each protrusion 33 . Therefore, the support base 2
0 and the step 30 does not require a hinge or the like, but it is preferable that each engagement hole 51 of the stopper 50 is formed slightly smaller than each protrusion 33 of the step 30. Further, an angle adjustment member 40 is inserted between the step stool 30 and the support base 20 assembled in this way. In this case, the protrusion 41 of the angle adjustment member 40 is fitted into the guide groove 23 of the base 20, and each of its teeth 42 is meshed with an arbitrary position of the tooth 22 of the base 20. After that, the top portion 4 of this angle adjustment member 40 is
If you place the step stool 30 on top of 3, the step stool 30 will become the support platform 2.
0, therefore it can be fixed to the floor etc. at any angle.

To perform stretching exercises using the auxiliary device 10, as shown in FIG.
If the person performing the gymnastics steps on the step stool 30 and performs forward bending or lateral bending movements as shown in the figure, it is possible not only to massage the tendons and calf muscles in particular, but also to fully stretch the back muscles. You can massage and loosen muscles throughout your body. At this time, if the semicylindrical member 60 is fitted into the vertical guide groove 31 of the step stool 30, when a person steps on the step stool 30, his or her feet will be shaped like a semicylindrical shape as shown in FIG. They will naturally lie parallel to each other along member 60. In this way, if the position of the feet is always parallel, the effect of stretching exercises will not change depending on the person, and the effect is that the feet can always be placed in the correct or appropriate position for stretching exercises. . Therefore, this semicylindrical member 60
can make stretching exercises more effective by always guiding the feet of the person doing stretching exercises to the appropriate position without being conscious of them. Furthermore, if this semicylindrical member 60 is fitted into the guide groove 32 on the side of the step stool 30, and a person performing stretching exercises places his or her feet on this semicylindrical member 60 (see Fig. 6), Since you will be bending your toes, you will be able to fully stretch your Achilles tendon.
This not only makes it possible to diversify stretching exercises, but also further enhances the effectiveness of the exercises.
Furthermore, by moving the angle adjustment member 40 back and forth, the angle of the step stool 30 can be changed arbitrarily, and gymnastics tailored to the person can be performed. That is, for people with flexible bodies, the effect of stretching the Achilles tendon etc. will not be enhanced unless the step stool 30 is set at a fairly steep slope; on the other hand, for people with stiff bodies, a steep slope should be used. This is because unreasonable force will be applied to the Achilles tendon, etc., and it is necessary to adapt the stretching exercises to the condition of the person performing the stretching exercises.
Also, considering the case where the same person uses this auxiliary device 10, the starting point of the exercise is the step stool 3 with a gentle slope.
This is because it is more effective to use the steeply sloped step stool 30 to further stretch the body after the body has gotten used to it and the muscles have loosened up to a certain extent in order to increase the effectiveness of the stretching exercises. In addition, support stand 2
If a scale corresponding to the angle of the step stool 30 is attached near the tooth portion 22 of 0, the angle of the step stool 30 can be immediately determined from the position of the angle adjustment member 40, and the strength of the stretching exercise (the angle of the step stool 30 is large You can select at a glance whether it is a high-intensity exercise or not.

In addition, in this embodiment, since the recesses 21 and 36 are formed in the support stand 20 and the step stool 30, when the auxiliary tool 10 is not used, the angle adjustment member 40
is stored in the recess 21 of the support stand 20, and then the step stool 3
0 is brought into close contact with the support base 20, the angle adjustment member 4
0 is accommodated in both recesses 21 and 36. Therefore,
This auxiliary tool 10 can be packed compactly when not in use, and does not take up much space. Furthermore, in the present invention, since the cushioning member 53 is attached to the upper front surface of the stopper 50, it goes without saying that a person's heel will come into contact with it during gymnastics for positioning, and the heel will not hurt when it comes into contact with it. Even if the heel moves up and down a little during exercise, it will not cause any scratches or the like.

Incidentally, the semicylindrical member 60 in the present invention
has a large number of small protrusions 63 to 63 on its upper surface, so it goes without saying that during the stretching exercises shown in FIG. 60, these small protrusions 63 to 63 stimulate the soles of the feet, especially the arches, and improve blood circulation.
It is also possible to achieve an effect equal to or greater than that of so-called green bamboo stomping.

The extension/flexibility exercise aid 10 according to the present invention has the above-mentioned configuration, and its size is such that a person can easily take a posture such as forward bending or side bending while standing on the step stool 30. good. In addition, the strength of the step stool 30 etc. may be sufficient as long as it can support the weight of a person.
Any material such as plywood or plastic may be used as long as the strength requirements are met. Further, the semicylindrical member may be fixedly provided either vertically or horizontally of the step.

As described in detail above, the extension/flexibility exercise aid 10 according to the present invention is not only useful for exercises that stretch the Achilles tendon, calf, etc., but also allows anyone to use it without being consciously aware of it. It is possible to meet the above requirements and also allow for diversification of flexibility exercises.
