Description

{MUSCLE STRENGTHENING CANE}

The present invention relates to a cane for strengthening muscular strength capable of applying a load to a user's upper arm by an elastic body provided in the cane body.

From the past, when the lower body is weakened and the body is abnormal, a walking stick is used to assist the walking. In addition, many exercise canes are used, such as downhill ski stock, cross-country ski stock, and Nordic walking poles. In such a cane, a cane having stretching means is used to absorb the impact transmitted from the ground to the body.

For example, Patent Document 1 discloses a walking aid walking stick 101 provided with a stretching means as shown in Fig. The upper portion of the intermediate pipe 130 is inserted from the lower end of the upper pipe 120 in the walking assistant walking stick 101. A bolt 131 is provided at the upper end of the intermediate pipe 130 and a coil spring 150 is provided between the upper pipe 120 and the bolt 131. One end of the coil spring 150 is fixed to the upper pipe 120 and the other end is fixed to the upper end of the intermediate pipe 130.

Therefore, when the lower end of the walking aid walking stick 101 is brought into contact with the ground, the coil spring 150 is compressed, and the shock from the ground is absorbed.

In this way, training is used to reinforce the strength of the upper arm using the action of the repulsive force against the force pressing the ground. Particularly, it is considered that the walking assistant walking stick 101 is improved and used for training of the downhill skiing, the cross country skiing, and the Nordic walking.

The point to be changed to make a cane for strengthening muscles is to lengthen the stretching length (stroke). In the walking assistant walking stick 101, only a few centimeters of the stretching length suffices because it is only intended to absorb the impact from the ground. If you stretch it longer than that, the walking becomes unstable. On the other hand, it is considered that a stroke about 20 centimeters is suitable for a muscle strengthening cane.

Thus, in the walking assistant walking stick 101, the extension and contraction length was determined to be about 20 centimeters. However, in order to compress the coil spring 150 by about 20 centimeters, the length of the coil spring 150 before compression is required to be several tens of centimeters, and the length of the bolt 131 becomes long. Therefore, it has been found that the weight of the whole of the walking assistant walking stick 101 is considerably increased in the structure similar to the walking assistant walking stick 101.

It is preferable to use a light weight stick as much as possible for the strength training for strengthening the force to suppress the cane on the ground. In the case of a heavy cane, the strength of the cane lifting force training is to train the muscles different from the purpose. Therefore, it has been found that the cane for strengthening muscles for achieving the object of the present invention needs to have a completely different structure from that of the cane for walking augmentation and to be lightweight.

In addition, it has been found that the length (stroke) to be stretched or shrunk must be easily adjustable by the user.

In addition, it has been found that the intermediate pipe 130 of the walking assistant walking stick 101 needs to be improved because the surface of the portion entering and leaving the upper pipe 120 is easily damaged by repeated sliding.

11, the walking assistant walking stick 101 includes an adjusting member 170 for inserting the lower pipe 140 from the lower end of the intermediate pipe 130 and adjusting the insertion length thereof . The adjusting member 170 is composed of a cap 171 and an adjusting ring 172. The lid 171 is provided with a female screw 175 and is screwed to a male screw 132 formed at a lower end of the intermediate pipe 130. The adjustment ring 172 has a vertical slit (not shown) and is capable of reducing the diameter, and is interposed between the lower pipe 140 and the lid 171.

A ring-shaped protrusion 176 is formed on the inner wall of the adjusting ring 172. A plurality of ring-shaped grooves 141 are formed on the outer surface of the lower pipe 140. When the cap 171 of the lid 171 is screwed to the male screw 132 of the intermediate pipe 130 so as to tightly tighten the lid 171, the adjusting ring 172 is contracted, (Not shown). At this time, the insertion length of the lower pipe 140 with respect to the intermediate pipe 130 can be adjusted by selecting the insertion groove 141.

However, the intermediate pipe 130 needs to be thicker in wall thickness in order to install the male screw 132. [ Therefore, the weight of the entire can is increased by the attachment of the adjusting member 170. That is, in the cane for reinforcing muscle strength of the present invention, it is necessary to develop a control member different in structure from the control member 170 to make the entire cane lighter.

Fig. 1 is a schematic view of a strength-building stick 1 as an example of the present invention. The cane body 10 of the strength reinforcing cane 1 is constituted by an upper pipe 20, an intermediate pipe 30 and a lower pipe 40. A grip portion 91 is attached to an upper end portion of the cane body 10 and a water tail portion 92 is attached to a lower end portion of the cane body 10. [

In the figure, an upper part of the intermediate pipe 30 is inserted into the upper pipe 20. The substantially entire length of the intermediate pipe 30 can be inserted into the upper pipe 20 by holding the gripper 91 and pressing the ground surface with the water tail 92. [ The stroke adjustment ring 80 can adjust the stroke length. A handle 93 is provided at the lower end of the intermediate pipe 30.

Fig. 2 shows a case where the characteristic configuration of the present invention is applied to the upper pipe 20 and the intermediate pipe 30. Fig. The upper pipe 20 is referred to as an outer pipe 11 and the intermediate pipe 30 is referred to as an inner pipe 12 in order to simplify the explanation.

The present invention is characterized in that an upper portion of the inner tube 12 is inserted from the lower end of the outer tube 11 and an elastic body 50 is provided between the inner wall of the outer tube 11 and the outer wall of the inner tube 12 . One end of the elastic body 50 is attached to the lower end of the outer tube 11 and the other end of the elastic body 50 is attached to the upper end of the inner tube 12. [ Due to this configuration, when the inner tube 12 is pushed into the outer tube 11, the elastic body 50 extends and acts on the returning reaction force.

The present invention is characterized in that a gap is formed between an outer tube (11) and an inner tube (12) and an elastic body (50) is provided in a narrow gap. In this figure, the clearance between the outer tube 11 and the inner tube 12 is largely described in order to clarify the structure, but it is preferable that the gap be as small as possible, preferably about 1 millimeter.

As the elastic body 50, a rubber cord or the like is preferable. In addition, for example, a coil spring can be used, but there is a possibility that the inner diameter of the coil is reduced due to the tensile force, so that the coil may come into contact with the outer surface of the inner tube 12. [ In order to prevent generation of a reaction force, it is necessary to increase the gap.

As a rubber cord, for example, a rubber cord is used as a core and the periphery thereof is threaded and formed into a string or a band. By using a strong thread made of resin, the elastic body 50 having a small frictional resistance on the outer surface and having abrasion resistance can be obtained. When the inner tube 12 is slid in the outer tube 11, the cord-like or band-shaped elastic body 50 smoothly moves between the tubes to provide a pleasant feeling of use.

Since the inner tube 12 comes into contact with the outer tube 11 through the elastic body 50 as well as the problem of the portion of the inner tube 12 coming into and out of the outer tube 11, The problem is solved.

Figs. 3A to 3C are sectional views taken along the line X-X in Fig. 2. Fig. 3A shows a case in which a pair of band-like elastic bodies 50 are used. 3B shows a case in which one tube-shaped elastic body 50 is used. 3C shows a case in which eight string-like elastic bodies 50 are used. In either case, a gap is formed between the inner wall of the outer tube 11 and the outer wall of the inner tube 12, and the elastic body 50 is provided in the gap.

The strength reinforcing cane 1 shown in Fig. 1 will be described in detail. 4 and 5, the upper pipe 20 and the intermediate pipe 30 are connected to each other by a connecting member 60 (hereinafter, referred to as " inner pipe portion ") composed of an inner ring portion 61 and an outer ring portion 62 . 4, an inner ring portion 61 of the connecting member 60 is attached to the lower end of the upper pipe 20 by adhesion or the like. 5, the intermediate pipe 30 is inserted into the shaft hole 64 of the foreign-exchange portion 62. In this case, The male screw 65 provided on the inner ring portion 61 and the female screw 66 provided on the outer ring portion 62 are screwed together so that the upper pipe 20 and the intermediate pipe 30 are stretchable .

4 shows that one end of the elastic body 50 is attached to the lower end of the upper pipe 20 and the other end of the elastic body 50 is attached to the upper end of the intermediate pipe 30 . 4, an elastic body 50 is provided at its one end with an engaging portion 51. A notch 63 provided at the lower end of the inner ring portion 61 is engaged with an engaging portion 51 can be interlocked. The engaging portion 51 can be inserted and fixed between the outer surface of the upper pipe 20 and the inner surface of the foreign body portion 62 when the foreign body portion 62 is screwed to the internal portion 61. [

5 shows a band-shaped elastic body 50 provided at the upper end of the intermediate pipe 30. As shown in Fig. As described above, by using one strand of the elastic body 50 reciprocally, two strands of the elastic body 50 can be formed. That is, one end of each elastic body 50 is attached to the lower end of the upper pipe 20 with the engagement portion 51. The other end is attached to the upper end of the intermediate pipe 30. The upper end of the intermediate pipe 30 has a stopper member 35 and is capable of attaching the elastic body 50 by the washer 36 and the screw 37.

As described above, in the strength reinforcing cane 1 of the present invention, the elastic body 50 is disposed in a narrow gap between the outer tube 11 (upper tube 20) and the inner tube 12 (intermediate tube 30) have. The elastic body 50 is lightweight by using a rubber cord. A thin aluminum-based alloy may be used for the outer tube (11) and the inner tube (12). The inside of the outer tube 11 and the inner tube 12 are almost hollow. A connecting member 60 is provided at the lower end of the outer tube 11 for attaching one end of the elastic body 50, but it is possible to use a resin to make it lightweight. As a result, the entire strength-building cane 1 can be considerably reduced in weight.

6A and 6B, the strength reinforcing cane 1 has a length capable of expanding and contracting by attaching / detaching the stroke adjusting ring 80 to the outside of the inner pipe 12 (intermediate pipe 30) Stroke) can be adjusted. The stroke adjusting ring 80 is formed with a slit 81 in the axial direction on the cylindrical member. The width of the slit 81 is set to 60% to 70% with respect to the outer diameter of the inner pipe 12 (intermediate pipe 30).

FIG. 6B shows a state in which the inner pipe 12 (intermediate pipe 30) is stretched to the maximum length in a no-load state. The dimension S1 from the lower end of the connecting member 60 to the upper end of the handle 93 is a length S1 capable of expanding and contracting without attaching the stroke adjusting ring 80. [ In addition, by attaching the two stroke adjusting rings 80, it is shown that the length S2 becomes as short as the stretchable length S2. In addition, by attaching a large number of stroke adjusting rings 80, the length of S 1 can be set to zero to be used as a normal walking pole.

As such, the stretchable length can be adjusted by varying the number of stroke adjustment rings 80. Alternatively, the length may be adjusted by using a stroke adjusting ring 80 having a different length.

7 shows a regulating member 70 whose length can be adjusted at the junction of the intermediate pipe 30 and the lower pipe 40. As shown in Fig. The adjusting member 70 is constituted by a shaft member 71 attached to the upper end of the lower pipe 40 and an adjusting ring 72 screwed and attached to the shaft member 71. When the lower pipe 40 is inserted into the intermediate pipe 30 and mutually rotated, they are mutually fixed at the position. A retaining ring 79 is provided at the tip of the shaft member 71 so that the adjustment ring 72 does not come off from the shaft member 71. Further, a handle 93 is provided at the lower end of the intermediate pipe 30, and a strong force can be applied when the handle 93 is fixed.

8 shows the structure of the adjusting member 70. Fig. The shaft member 71 has a male screw 73 at the upper end and a slope 75 at the lower pipe 40 side. The adjusting ring 72 is provided with a female screw 74 on one side and a braking body 76 formed by dividing a cylinder into four parts by a slit 78 on the other side. The diameter of the fuselage 76 is enlarged by the inclination 75 when the female screw 74 is screwed to the male screw 73 and the fuselage 76 is brought into contact with the tilt 75. [

7, the upper portion of the lower pipe 40 is inserted into the lower end portion of the intermediate pipe 30 and the both are rotated in the direction in which the screws are tightened. At this time, the adjustment ring 72 is lightly fitted to the intermediate pipe 30 and is not slid. The fuselage 76 extends along the slope 75 and is expanded so that the outer periphery thereof is strongly pressed against the inner wall of the intermediate pipe 30 so that the intermediate pipe 30 and the lower pipe 40 are fixed . At this time, the insertion length is free, and the insertion length can be adjusted and fixed.

The adjustment member 70 is a small component that is simple in structure and is inserted into the intermediate pipe 30. The shaft member 71 and the adjustment ring 72 can be made lightweight by resin. The intermediate pipe 30 and the lower pipe 40 may be made of a thin aluminum-based lightweight alloy. Therefore, the adjustment member 70 can be made light in weight.

2, the elastic body 50 is disposed between the inner wall of the outer tube 11 and the outer wall of the inner tube 12 and has one end attached to the lower end of the outer tube 11 and the other end connected to the inner tube 12, As shown in Fig. The method of attaching the elastic body 50 is not limited to this, and one application example is shown in Fig.

9, a plurality of openings 15 (for example, 15a, 15b, 15c ...) are provided at the lower end of the outer tube 11 and a plurality of openings 16 , 16a, 16b, 16c, ... along the circumference. One strand of elastic body 50 can be sequentially attached to the openings 15 and 16.

For example, one strand of elastic body 50 can be inserted from the outside of the opening 15a inward, from outside the opening 16a, from the inside of the opening 15b, out of the inside of the opening 16b, And finally both ends of the elastic body 50 can be fixed outside the outer tube 11 to be fixed. A plurality of elastic bodies 50 are disposed between the inner wall of the outer tube 11 and the outer wall of the inner tube 12 and one end of each elastic body 50 is attached to the lower end portion of the outer tube 11, (Not shown).
