Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention mainly relates to both arms,
The present invention relates to a telescopic-type exercise assisting device that can be used to perform opening / closing motions of both legs and the like to perform training of each related body part.

[0002]

2. Description of the Related Art Conventionally, as a telescopic type exercise assisting device of this type, a plurality of spring members are arranged between locking members at both ends, and a grip portion is provided on each outer side of the locking members at both ends. An instrument called an expander that is configured to be known is known.

In this device, the grips at both ends are usually grasped by both hands, and the spring material is extended by expanding between the arms, and after the maximum expansion, the spring material acts to the original size. The distance between both arms is reduced while allowing the reduction, and by repeating the above cycle, it is used for training the arms and chest. Of course, in addition to this, fix one grip part with one foot, grasp the other grip part with the corresponding one hand, pull up the grip part with this hand to extend the spring material, and after extension, the spring There is also a method of training the corresponding arm by repeating the cycle of pulling down the hand while allowing the material to shrink.

According to such an expander, as described above, the training is performed mainly by utilizing the acting force of the spring material in one direction, so that the training for the expansion side is performed. The training does not work on the contraction side, and since the spring material is used, the acting force gradually increases as it extends, etc. It is possible to change the magnitude of the acting force by increasing or decreasing the number of spring members arranged between the locking members. It is impossible to let them do it. Other than the expander, there are telescopic type exercise assisting tools, but the above is almost the same.

Therefore, first of all, the telescopic type exercise assist of the present invention
The outline of the operation of the tool is as follows. First, the lower end of the hose member is put in a liquid, for example, water, and then fixed to each of the arms by attaching means at both ends, or the grip member is grasped by each of the both hands, and the both arms are grasped. By performing the opening / closing operation of, both arms and chest can be trained.

First, by moving both arms in the direction of reducing the space between them, the elastic member is contracted to the minimum extent, and then moving both arms so that the space between them expands. Water is introduced through the hose member. After that, when the extension and contraction between both arms is repeated, water is discharged from the elastic member or introduced into the elastic member, and this is repeated, and the action caused by the flow resistance at the time of introducing and discharging water. The power will be available for training.

In this case, the water only reciprocates through the hose member, and the control means is inserted in the middle of the water flow.
Incoming and outgoing flow resistance must be controlled separately
For example, since the flow resistance is the same in both reciprocating directions, the acting force is the same in both directions of expanding and contracting both arms. However, it is possible to effectively perform the movement in the direction of reducing the distance between the arms, which is not possible with the conventional expander or the like.

In the above description, only the lower end of the hose member is put into water and used for exercise.
The telescopic type exercise assisting tool of the present invention can be used by a person who uses the same after putting it in a pool, a bath or the like, and putting the whole in the pool or the bath as well. Its own weight is reduced by buoyancy, making it easier for people without physical strength to use.

In the above description, only the case of using for expanding / reducing the distance between the arms is explained, but it can also be used for similar motions of both legs or other similar motions, and the mounting means or grips. If one of the members is fixed to something, it can be used to exercise only one arm or leg.

Therefore, according to the telescopic type exercise assisting tool of the present invention, it is expected that the use of the same will enhance the muscle strength of the arms and legs, the beauty effect such as bust up and hip up, and the medical effect such as exercise for incontinence. be able to.

Further, each characteristic structure of the present invention will be described below.

It

[0015]

A control means for controlling the resistance of the flow of liquid flowing in the hose member is inserted in the middle of the hose member.
In that case, it is possible to appropriately adjust the amount of exercise required for expanding and contracting the elastic member.

[0017] Then the above control means, by constituting so as to be respectively independently controlled for resistance of the inflow direction and the outflow direction of the flow, to be adjusted separately momentum required for extension direction or reduction direction of the elastic member it can. Therefore, for example, when performing the exercise of expanding and contracting both arms,
It becomes possible to perform an operation in a narrowing direction rather than a widening direction with a weak force.

The control means includes two passages arranged in parallel between the two inlets and outlets, a check valve arranged to allow only flows in opposite directions to the passages, and the both passages. The flow resistance of the liquid can be changed for each flow direction with a simple configuration by configuring the flow path cross-sectional area changing means arranged to change the cross-sectional area in the middle of each.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail based on examples with reference to the accompanying drawings. Figure 1
3 shows Embodiment 1 to which the present invention is applied.
2 is a partially cutaway front view thereof, FIG. 2 is a vertical cross-sectional front view of the controller, and FIG. 3 is a cross-sectional view taken along the line AA of FIG. FIG. 4 is a partially cutaway front view of the second embodiment to which the present invention is applied.

(Embodiment 1) As shown in FIG. 1, a stretchable portion (stretchable member) 1, mounting belts 2 fixed to both ends thereof, and a hose (hose member) connected to the central portion of the stretchable portion 1. ) 3 and a controller (control means) 4 interposed in the middle of the hose 3 constitute a telescopic type exercise assisting tool as a basic constituent element.

As shown in FIG. 1, the expandable portion 1 is constructed as a bellows-shaped tubular body with both ends closed, and each of the bellows-shaped tubular bodies has a pair of closed support bellows on the outer end side. Cylinder 1
a, 1a, and a coupling cylindrical body 1b interposed between the inner ends of the pair of support bellows-shaped cylindrical bodies 1a, 1a. The coupling cylinder 1b is used to couple the pair of supporting bellows-shaped cylinders 1a, 1a via the same.

As shown in FIG. 1, by connecting the upper end of the hose 3 to the coupling cylinder 1b, as described above,
The hose 3 is communicated with the central portion of the stretchable portion 1.

As shown in FIGS. 2 and 3, the controller 4 has two doorways 4 formed in a case body 4a.
b and 4c, connection spaces 4d and 4e formed inside the respective entrances and exits 4b and 4c, and two flow paths arranged in parallel between the two entrances and exits 4b and 4c through the connection spaces 4d and 4e, respectively. 4f and 4g, and the corresponding connection space 4 so as to allow only flows in opposite directions to the flow paths 4f and 4g.
Check valves 4h and 4i arranged in d and 4e, and the both flow paths 4
Edge-shaped pressing members 4j, 4g arranged so as to be capable of advancing and retracting in a direction orthogonal to these with respect to f and 4g, respectively.
k and nut members 4n and 4o coupled to the rear portions of the respective edge-shaped pressing members 4j and 4k, which move forward and backward by the rotation of the screw members 4l and 4m.
Nuts 4n and 4o for pushing and retracting j and 4k, and a dial 4 for rotating the screw members 4l and 4m.
p and 4q.

Both ends of the two flow paths 4f and 4g are rigidly formed integrally with the case body 4a, but they are made of a pipe material having elasticity in the middle thereof. The edge-shaped pressing member 4
j and 4k are in contact with each other, and if necessary, they can be advanced to recess the relevant part and reduce the cross-sectional area of the part.

When any one of the dials 4p and 4q is rotated in a predetermined direction, the screw members 4l and 4m rotate in the corresponding direction, the rotation is restricted, and the nut member arranged so as to move back and forth. 4n, 4o advance or retreat accordingly, and naturally, the edge-shaped pressing members 4j, 4k advance or retreat in the transverse direction from the side surfaces of the flow passages 4f, 4g, thereby cutting off the site. The area can be reduced or increased (returned to the original cross-sectional area). Needless to say, by performing different operations for each of the dials 4p and 4q, the flow path 4
It goes without saying that the cross-sectional areas of f and 4g can be different from each other.

The flow of liquid from the former to the latter of the inlets / outlets 4b, 4c, and from the latter to the former is respectively confirmed by check valves 4h and 4h.
By the action of 4i, it is performed through different flow paths 4f and 4g. That is, the flow of the liquid from the inlet / outlet 4b to the inlet / outlet 4c is performed through the flow passage 4g, and the flow of the liquid from the inlet / outlet 4c to the inlet / outlet 4b is performed through the flow passage 4f.

The inlet / outlet 4b of the controller 4 is connected to the upper side of the hose 3, and the inlet / outlet 4c is connected to the lower side of the hose 3. Further, an annular weight 5 is externally fixed to the outer periphery of the hose 3 immediately before the lower end.

As shown in FIG. 1, the attachment belts 2 and 2 are fixed to the outer ends of the expansion and contraction portion 1, respectively, and a large number of hooks are provided on the outer surface of one end and the inner surface of the other end. Each of the planted coupling means is constituted. The mutual coupling means can be coupled by pressing the coupling means face to face. Further, the connection can be easily released by peeling it off from any one of the edges.

Therefore, according to the telescopic type exercise assisting tool of the first embodiment, at least the lower end of the hose 3 is immersed in a liquid, for example, water, and then the attachment belts 2 and 2 at both ends are attached to each other. It is possible to perform training on both arms and the chest by wrapping around the arm, fixing the wrapping state by the connecting means, and then opening and closing the both arms. Alternatively, the attachment belts 2 and 2 may be respectively wound around the legs, the wound state may be fixed by the coupling means, and then the legs may be opened and closed to train the muscle strength around the legs. It goes without saying that training of other regions can be performed in the same manner.

First, the case where the attachment belts 2 and 2 are fixed to both arms and exercise is performed in a pool will be described as an example. In this case, first, when both arms are moved in a direction to reduce the distance between them to reduce the stretchable portion 1 to the minimum extent, the air inside thereof is expelled through the hose 3, and then,
When both arms are moved so as to expand between them to extend the stretchable portion 1, the inside thereof is depressurized and the water in the pool is introduced through the hose 3.

After that, when the expansion and contraction between both arms are repeated, the water in the expansion / contraction part 1 is discharged into the pool or introduced into the expansion / contraction part 1, and this is repeated to introduce water. The action force generated by the flow resistance at the time of discharge can be used for training. The flow resistance of water is generated in all parts where the flow occurs, but it is particularly large in the thin flow paths 4f and 4g in the controller 4, and in the controller 4, the flow paths 4f and 4g are large.
By changing the cross-sectional area of g, change the flow resistance of water,
The amount of exercise can be adjusted appropriately.

For example, by turning the dial 4q, the flow path 4
When the cross-sectional area of g is reduced, the resistance of the water flow in the direction of contracting the expansion / contraction part 1 can be increased, and the momentum in this direction can be increased. Conversely, when the dial 4p is turned to reduce the cross-sectional area of the flow path 4f, the resistance of the water flow in the direction of extending the expansion / contraction portion 1 is increased, and the momentum in this direction can be increased.

If the flow resistance is adjusted to a constant value by the dials 4p or 4q, the resistance is increased in all strokes in the direction of expanding or contracting the expansion / contraction portion 1 in any direction of flow. Does not change. Therefore, the movements for expanding and contracting the distance between the arms can be performed with corresponding constant forces, and the movements do not gradually increase or decrease.

Therefore, according to the telescopic-type exercise assisting tool of the first embodiment, first, since there is flow resistance in both the direction of expanding and contracting the elastic part 1, the distance between the arms is increased. It can be used for training in both directions such as the expansion and contraction directions. In addition, since the required momentum can be adjusted by adjusting the resistance of the corresponding flow of the liquid in each of the extension direction and the contraction direction of the elastic portion 1 as described above, for example, the distance between the arms can be adjusted. It is possible to adjust each required amount of exercise in accordance with the exercise ability in the expansion direction and the exercise capacity in the reduction direction.

As described above, when the telescopic exercise assisting device of the first embodiment is used in a pool (the same applies to a bathtub etc.), the weight of the device itself is reduced by buoyancy, and the person who has no physical strength. However, it is already easy to use.

In addition, in the above, only the case of using for expanding and contracting the space between the arms has been described.
It can be used for similar movements of both legs or other similar movements, and if one attachment belt 2 is fixed by the foot, it can be used for movement of one arm, and one attachment belt 2 is fixed by some fixing means. If fixed, it can also be used to exercise only one arm or leg.

Therefore, according to the expansion-contraction type exercise assisting tool of the first embodiment, it is utilized to strengthen the muscle strength of the arm or leg,
It can be expected to have beauty effects such as bust and hip up, and medical effects such as incontinence exercise.

(Embodiment 2) As shown in FIG.
In the expansion-contraction type exercise assist tool of FIG. Is only different from. All other components are the same as those of the first embodiment, and the same components are designated by the same reference numerals.

Therefore, only the structure different from that of the first embodiment will be described here. As shown in FIG. 4, the expansion / contraction part 11 is configured as a bellows-shaped tubular body with both ends closed. The bellows-shaped tubular body is formed with a pair of closed support bellows-shaped tubulars on the outer end side. The bodies 11a and 11a, each of which has a tapered bellows-like tubular body 11a, 11a having a larger diameter toward the inner end side, and a pair of the branching bellows-like tubular bodies 11a, 1a.
It is composed of a coupling cylinder 11b interposed between the inner ends of 1a. Needless to say, the connecting cylinder 11b is for connecting the pair of supporting bellows-shaped cylinders 11a, 11a via the pair of supporting bellows-like cylindrical bodies 11a, 11a.
11a has a large diameter corresponding to the large diameter of the inner end.

Therefore, it can be used in exactly the same manner as the telescopic type exercise assisting tool of the first embodiment, and the same action and effect can be obtained. When it is expanded and contracted with both arms fixed to, it can be expanded and contracted while maintaining a linear state without being bent in the middle.

[0042]

Therefore, according to the telescopic type exercise assisting tool of the present invention, at least the lower end of the hose member is immersed in a liquid, for example, water, and then the attaching means or the grip members at both ends are required to move. For example, by attaching to each of both arms and performing an opening / closing operation between the both arms, the elastic member can be expanded / contracted, and training of the exercise-required parts such as both arms and chest can be performed.

More specifically, both arms are moved in a direction in which the space between them is contracted to contract the elastic member to the minimum extent,
Then move both arms so that the space between them expands,
The inside of the elastic member is decompressed, and water is introduced through the hose member having at least its lower end immersed in water. After that, when the stretching between the arms is repeated, the water is discharged from the elastic member or introduced into the elastic member.
This is repeated, and the action force generated by the flow resistance at the time of introducing and discharging water can be used for training.

When the control means is not used, the water in the elastic member only reciprocates through the hose member in response to expansion and contraction, and the flow resistance is the same in both directions of reciprocation. -The action force will be the same in both directions of contraction. However, it is possible to effectively perform the movement in the direction of reducing the distance between the arms, which is not possible with the conventional expander or the like.

By the way, the telescopic type exercise assisting device of the present invention can be used by a person who uses the same after putting it in a pool, a bathtub or the like and putting the whole in the pool or bathtub. In this case, the weight of itself is reduced by the buoyancy, and it becomes easy for a person without physical strength to use.

The telescopic type exercise assisting tool of the present invention is
It can be used not only for expanding and contracting the space between the arms but also for similar motions of the legs or other similar motions, and if one of the attachment means or the grip member is fixed to something, one arm or It can also be used to exercise only one leg.

Therefore, according to the telescopic type exercise assisting tool of the present invention, it is expected to be used for strengthening the muscle strength of arms and legs, beauty effects such as bust up and hip up, and medical effects such as incontinence control exercise. can do.

In the present invention as described above, when the bellows-shaped tubular body having both ends closed is used as the elastic member, the elastic member can be easily constructed.

The above-mentioned closed bellows-shaped cylinders are arranged such that a pair of closed support bellows-shaped cylinders on the outer end side and the pair of support bellows-shaped cylinders are arranged between their inner ends. In the case of adopting a structure in which the hose member is connected to the connecting cylinder by connecting the hose member to the connecting cylinder, the liquid to the bellows cylinder forming the elastic member is It can be introduced and discharged appropriately.

[0050]

When a control means for controlling the resistance of the flow of the liquid flowing through the hose member is inserted in the middle of the hose member, the momentum required for expanding and contracting the expansion / contraction member can be appropriately adjusted.

[0052] The above control means, because there was each configured to be separately controlled <br/> the resistance of the inflow direction and the outflow direction of flow, to individually adjust the extension direction or movement amount required for the reduction direction of the elastic member can do. Therefore, for example, in the case of expanding / reducing the movements of both arms, it is possible to make the movement in the direction of narrowing the direction of widening with a weak force or vice versa.

Specifically, the control means includes two flow passages arranged in parallel between the two inlets and outlets, and a check valve arranged to allow only flows in opposite directions to the both flow passages. , The flow passage cross-sectional area changing means arranged to change the cross-sectional area in the middle of each of the both flow passages, so that the resistance of the liquid flow can be changed for each flow direction with a simple configuration. You can

[0054] Also, the two flow paths are constituted by a pipe material having flexibility, the flow path cross-sectional area changing means for pipe member constituting the two flow paths, each said pipe member from the outside An edge-shaped pressing member arranged so as to be capable of advancing and retreating in a direction orthogonal to, an advancing / retreating operation mechanism for advancing / retreating a pressing member by advancing / retreating a nut by rotating the screw member, and a screw member of the advancing / retreating operation mechanism. since configured in the dial for rotational operation, it is possible to constitute very easily the flow path cross-sectional area changing unit, usability is good.
