Description

The present invention relates to an improvement of a stretchable tilting table that sits on a tilting table and performs forward bending movement of the upper body, stretching of the lower limb rear muscles, and the like.

If for some reason the muscles in the back of the thigh (back thigh muscles) are continuously excited abnormally and the muscles contract, the movement of the pelvis is restricted. . In the orthopedic field, the frequency of such diseases is high.

In the treatment of such diseases, stretching of the back thigh muscles and anteroposterior movement of the pelvis are effective. However, since the back thigh muscles are large, it is difficult to perform sufficient stretching manually. For this reason, an inclined table as shown in FIG. 5 is often used. When the tilting table is used, it is possible to perform a forward bending exercise using the weight of the upper body, so that the leg muscles can be effectively stretched.
In many cases, there is an abnormality in the muscle group in the back of the lower leg (back leg), but the tilt table can also be used for this stretch.

A conventional tilting table for stretching is a tilting plate (seat surface) provided with an inclined surface, and a sole plate is provided, and a forward bending motion is performed by sitting on the inclined plate and applying the sole to the sole plate (for example, patent) References 1 and 2). Some use the weight of the weight to assist the forward bending motion (see, for example, Patent Document 3). In some cases, the inclined plate is provided only on a part of the inclined surface (for example, see Patent Document 4).
These techniques are described below with reference to the drawings.
56-152676 61-21079 Patent No. 3052130 JP 10-155935 A

FIG. 3 (A) shows an embodiment shown in Patent Document 1, in which a foot plate (2 in the figure) is provided at one end of an inclined plate (1 in the figure) at an angle of 90 °, and a support leg (see FIG. 3). No. 4) is provided to form a tilting table.
Sitting on an inclined plate, placing the sole on the sole plate, and bending the upper body forward, the back and thigh muscles can be stretched.
FIG. 3B shows an embodiment shown in Patent Document 2, which is substantially the same in structure and usage as Patent Document 1, but is characterized in that the angle of the sole plate can be adjusted. However, this is also used after the angle of the sole plate is adjusted.

FIG. 3 (C) shows an embodiment shown in Patent Document 3, in which an arm arm is provided on an inclined base, a weight is provided on the arm arm, and the arm arm is provided to assist the weight of the weight to bend forward. It is intended to exercise. Again, the angle of the soleplate is fixed.
FIG. 3 (D) shows an embodiment shown in Patent Document 4, in which a chair is tilted, and a tilting base is formed together with a foot pad (3-1 in the figure).

As described above, the sole plate of the conventional stretching ramp has a fixed angle and receives the entire sole. In other words, the ankle joint was fixed during training. For this reason, when the restriction of the pelvic movement is strong, it is difficult to bend forward, so stretching of the back thigh muscles and the back leg muscles cannot be performed well, and the effect may not be obtained.

In addition, the conventional apparatus is not manually rubbed. The tilt table is used by people with lower limb rear muscle group tension, pelvic movement limitation, low back pain, etc., but such people also have problems with standing balance, so there is a risk of falling when getting on and off the tilt table was there. Moreover, there was a risk of falling and falling when exercised on a tilt table.

In addition, when the knee joint is deformed, the knee floats when sitting, and it cannot sit stably on the tilting table, so there is a risk of falling, and effective forward bending exercises and muscle stretching are difficult. there were.

In order to solve these problems, in the invention described in claim 1, the seat surface 1 on which the trainee sits is provided on the inclined surface, and the foot support 3 is provided below the seat surface 1. In the tilting table for stretching that puts the foot on the foot support 3 and performs the forward bending motion of the upper body, etc.
Sitting on the seat surface 1, with the soles touching the foot support 3, provide the foot support 3 away from the seat surface 1 to the extent that ankle joint movement is possible, and move the heel toward the sole with the foot support 3 as a fulcrum Ankle joint movements can be performed, and muscle groups can be stretched in the rear thigh muscle group and the lower leg thigh.

Further, in the invention described in claim 2, hand-rubbing is provided so that it can be held by hand when sitting on the tilting table, and it is possible to safely get on and off the tilting table and exercise on the tilting table.

Furthermore, in the invention described in claim 3, a pillow is placed behind the knee of a person sitting on a tilting table so that exercise can be performed with the knee slightly bent.

According to the first aspect of the present invention, not only can the body bend forward in the same manner as in the past, with the foot resting on the seat surface 1 and the foot support 3, Even if it does not perform, it is possible to stretch the posterior thigh muscle group and the posterior thigh muscle group simply by performing an ankle movement so that the heel protrudes downward with the foot support 3 as a fulcrum.

With the conventional device, it was not possible to stretch the lower limbs muscles without performing forward flexion of the upper body, so those who have strong pelvic movement restrictions and cannot perform forward flexion of the upper body are recommended. I could not stretch. Even so, when I tried to stretch, I forced myself to bend forward and had little effect on my efforts.

On the other hand, when the tilt base according to the present invention is used, when it is difficult to bend the upper body due to abnormal tension of the lower limb muscle group, first, the ankle joint exercise is performed to stretch the muscle group of the lower limb rear part. This can alleviate pelvic movement limitations. Once the pelvic movement restriction is relaxed, the upper body can be bent forward, so when the upper body is bent forward, the muscles of the lower limbs are also stretched, and the pelvic movement restriction is further relaxed. If you continue, you can effectively relieve problems such as back pain.

In the invention of claim 2, since the slope is provided with hand-rubbing, it can be caught by hand-rubbing when getting on and off the slope base or exercising on the slope base, there is no risk of falling or falling, and it is safe. You can focus on training safely. For this reason, it is possible to more effectively perform the forward bending motion of the upper body and the stretching of the rear leg muscle group.

In the invention of claim 3, since a pillow is placed behind the knee of a person sitting on a tilting table so that the exercise can be performed with the knee slightly bent, Even when the joint is contracted while being deformed, it is possible to stably sit on the tilting table, so that it is possible to perform stretching and forward tilting motion safely and effectively. In addition, when the lower limb muscle group is stretched, joint deformation may be corrected.

In the invention of claim 1, the trainee sits on the seating surface 1 and places the sole on the foot support 3, so that the heel is slightly lifted from the seating surface 1, and the foot support 3 is used as a fulcrum. The ankle joint movement can be performed by moving in the direction of the sole, that is, in the direction of the arrow F shown in FIG. When this exercise is performed, the distance from the sitting position to the heel increases, so that the muscle group in the rear part of the lower limb can be effectively stretched. In other words, according to the present invention, the muscles of the rear part of the lower limbs, i.e., the rear thigh muscle group and the lower back part of the thigh, can be obtained simply by performing the ankle joint movement on the tilt table without performing the forward bending motion of the upper body. The muscle group can be stretched. As a result, the pelvic movement restriction is eased and diseases such as back pain can be alleviated.

An embodiment of the claimed invention is shown in FIG. 1A is a perspective view of the apparatus, FIG. 1B is a front view, and FIG. 1C shows a state where training is actually performed using the apparatus. In the figure, reference numeral 1 denotes a part where the trainee sits on the seat surface, 2 denotes a support leg constituting the inclined surface of the tilt table, and 3 denotes a foot support on which the trainee's foot is placed.

As shown in FIG. 1 (B), the foot support 3 is rotatably provided at a position of the axis O away from the inclined surface (seat surface 1 in the illustrated example). The axis O is an axis parallel to the transverse direction of the inclined surface. In this example, the distance from the seat surface 1 to the foot support 3 is about the size of the foot (length from the heel to the toe). In this embodiment, the foot support 3 is a plate and is provided so as to be rotatable about the axis O. The width of the foot support 3 is such that both feet can be placed together.

When the user sits on the seating surface 1 and touches the toes to the foot support 3, the heel is slightly lifted from the seating surface 1, as shown in FIG. For this reason, the ankle joint can freely perform dorsal flexion movement in this state. In this state, as shown in FIG. 1 (C), when the heel is projected in the direction of the sole (the direction of the arrow F in the figure), the ankle joint is in a dorsiflexion position where the foot is warped. Since the foot support 3 is provided so as to be rotatable about the axis O, this ankle joint movement can be performed smoothly. At this time, the sitting position does not change, and the heel is pushed forward, so that the back thigh muscles and the back leg muscles are stretched, and these muscle groups can be effectively stretched.

In the conventional device, the sole plate is fixed and supports the entire sole, so the ankle joint is fixed, and only the upper body can bend forward, and this exercise can be used to stretch the back thigh and back leg muscles. It was something to do.
For this reason, when the pelvic movement is strongly restricted due to abnormalities in the back thigh muscles, the forward bending movement cannot be performed, and therefore the muscles in the rear part of the lower limbs cannot be effectively stretched.

According to the apparatus of the present invention, even if the forward bending movement of the upper body is not performed, the sole is applied to the foot support, and the heel is protruded toward the sole, that is, in the direction of the arrow F shown in FIG. When exercise is performed, it is possible to stretch the back thigh muscles and the back leg muscles. This is the greatest feature of the invention described in the claims.

Stretching the muscles at the back of the lower limbs also relaxes the pelvic movement restrictions, allowing for forward bending of the upper body. If the upper body can bend forward, the lower limb muscles can be stretched more effectively. In this way, the muscles can be effectively stretched, the pelvic movement restriction can be relaxed, and the resulting back pain can be alleviated.
That is, stretching of the lower limb muscle group when there is a strong pelvic movement restriction that has been difficult in the past can be effectively performed in the invention described in the claims.

In the invention according to claim 2, in order to safely get on and off the ramp and to perform training on the ramp, a hand rub 4 is provided in the vicinity of the seat as shown in FIG. In the figure, the handle of the round pipe is provided almost horizontally. However, any shape, mounting position, mounting angle, material, etc. may be used as long as it can be held and stabilized.

When a patient with a deformed knee joint, such as knee osteoarthritis, rests on the tilt table, the knee floats and becomes unstable, and there is a risk of falling, etc., and training cannot be performed with confidence.
The invention according to claim 3 is to allow such a patient to sit stably and to perform training safely, and to use the pillow 5 at the position of the knee of the seat surface 1. I made it. This may be fixed using a hook-and-loop fastener or the like, or may not be fixed.

In the first aspect of the present invention, the size and shape of the seating surface 1 are not limited as long as the user can sit on the seating surface 1 and support the sole with the foot support 3 to perform ankle joint movement. As shown in FIG. 3D, the seat surface 1 may be provided on a part of the inclined surface.

Further, since the invention according to claim 1 only needs to be able to perform an ankle joint movement while the sole is in contact with the foot support 3, the foot support 3 may be brought close to the inclined surface to about half the size of the foot. Good. As shown in FIG. 3D, when the seating surface 1 is provided on a part of the slope, the ankle joint can be exercised regardless of the position of the foot support 3 on the sloped surface, and the muscles of the rear part of the lower limbs are stretched. It can be performed.
That is, the attachment position of the foot support 3 is not limited, and in short, an ankle joint motion may be made possible.

The foot support 3 is shaped like a plate in the embodiment of FIG. 1, but it can be rotated around the axis O as shown in FIG. 1 using a round bar, a polygonal bar, or a sole plate like a conventional tilt margin. Any shape, such as a provided one, may be used.
Further, although the foot support 3 is provided so as to be rotatable about the axis O, it may be fixed so as not to rotate. In short, it is only necessary that the ankle movement is possible.

It is an Example of this invention, (A) is a perspective view of an apparatus, (B) is a front view of an apparatus, (C) is a figure which shows a mode that it sits on an apparatus and stretches back thigh muscles and back leg muscles It is. A mode that training is performed by the invention of claim 3 is shown. It is an example of a conventional tilting table, (A) is an embodiment described in Japanese Utility Model Publication No. 56-152676, (B) is an embodiment described in Japanese Utility Model Publication No. 61-21079, and (C) is Japanese Patent No. 3052130.
