Description

  The present invention relates to an underwater walking pole that assists walking in water, and more particularly to an underwater walking pole that is self-supporting in water.

  Conventionally, underwater walking movements have been actively performed in pools and the like. Underwater walking is performed for the purpose of rehabilitation effects and exercise effects for middle-aged and elderly people because it can reduce the burden on the hips and knees. In addition, since calorie consumption is higher than walking on land, it is performed for the purpose of combating obesity. However, when walking underwater, the posture tends to become unstable, and it is difficult for middle-aged and beginners to perform for a long time, so a leader is often required to perform effective exercise. In other words, it is not something that can be done easily like a walk on land.

  In order to solve such a problem, Patent Document 1 proposes a rehabilitation-only pool. The pool includes a circulation generator that generates a circulation along the outer periphery of the pool, a walking training section including a pedestrian handrail and a gently inclined floor, a suspension training section including a suspension bar, and the like. Further, Patent Document 2 proposes a personal underwater walking apparatus that can perform underwater walking alone. However, installation of equipment for underwater walking that is different from a normal pool requires high costs, so it cannot be made inexpensive and easy to use.

  Therefore, there is a demand for means that allows even a middle-aged beginner to easily start underwater walking in a normal pool. The inventors of the present invention have come up with an underwater walking pole based on the experience of manufacturing a ski pole and a land walking pole for many years, and decided to make a prototype and a practical application test thereof.

  As a result of trial manufacture and trial use of an underwater walking pole, it was found that the use of the pole stabilizes the posture in water and facilitates walking, and can be an effective assisting means for rehabilitation and exercise for middle-aged and elderly people. And it was possible to confirm the items necessary to make a better auxiliary means. In other words, it was found that the form should be greatly changed, not the same as a pole for walking on land.

And it is possible to perform underwater walking according to each person's purpose, from rehabilitation walking with reduced load on the waist and knees to powerful walking against water resistance. Moreover, since the rehabilitation effect and the exercise effect can be realized, it is performed continuously for a long period of time.

  The underwater walking pole of the present invention has a structure in which it floats in water and the gripping part is located in the vicinity of the water surface. For this reason, even when the hand is released from the gripping part, the gripping part is not far from the hand. Further, by increasing the buoyancy and causing the gripping portion to protrude from the water surface, the gripping portion can be visually observed even from a position far away. For this reason, it can be used without feeling the stress of possessing extra items.

It is the schematic which shows the internal structure of a pole main body. It is the schematic which shows an example of the attachment method of a weight. It is the schematic which shows another example of the pole for underwater walking. It is AA arrow sectional drawing in FIG. 3A. It is the schematic which shows another example of the pole for underwater walking. These are explanatory drawings which show the relationship between a user and a pole.

  FIG. 1 is a schematic view of an underwater walking pole 10 which is an example of the present invention, and shows a state in which the pole is left in water. The underwater walking pole 10 includes a cylindrical pole body 20, a grip portion 30 located at the upper end of the pole body 20, and a stone thrusting portion 40 located at the lower end of the pole body 20.

  The underwater walking pole 10 has an overall specific gravity of less than 1 and does not sink into the water. Further, the pole body 20 is configured by an upper portion 21 having a specific gravity of 1 or less and a lower portion 22 having a specific gravity of 1 or more, so that the position of the center of gravity is sufficiently below. Accordingly, when left in sufficiently deep water as shown in FIG. 1, the stone thrusting portion 40 is positioned toward the water bottom 82 and the gripping portion 30 is positioned in the vicinity of the water surface 81. That is, the underwater walking pole 10 is self-supporting in water.

  In addition, when left in shallow water, the whole is inclined, the stone thrusting portion 40 is attached to the water bottom 82, and the grip portion 30 is positioned in the vicinity of the water surface 81. With such a configuration, even when the user releases the hand from the grip part 30, the grip part 30 does not sink into the water, and the grip part 30 is not far from the hand.

  2A to 2C show a specific structure of the underwater walking pole 10. 2A shows the main components, FIG. 2B shows the internal structure of the pole body 20, and FIG. 2C shows an example of how to attach the weight 50. As shown in FIG.

  As shown in FIG. 2A, the underwater walking pole 10 includes a grip portion 30 and a stone thrusting portion 40 at the upper and lower ends of the cylindrical pole body 20, and a rod-like shape is provided inside the lower side portion 22 of the pole body 20. Weight 50 is provided. As a material of the pole body 20, a high-strength aluminum alloy pipe can be used as in the case of ski poles.

  As the grip portion 30 and the stone thrusting portion 40, those used for ski poles or the like can be used. That is, the gripping part 30 and the stone thrusting part 40 are provided with mounting holes for inserting the pole body 20 and can be fixed with screws or the like as necessary. In addition, the grip part 30 uses what has clear directionality in the poles 11 and 12 for underwater walking mentioned later.

  The underwater walking pole 10 is used underwater, and has an overall specific gravity smaller than 1 so as to float in water. Further, it is necessary to configure so that water does not enter the inside of the pole body 20. For this reason, when using a commercially available pipe as a raw material of the pole main body 20, the upper and lower sides must be sealed.

The underwater walking pole 10 has a specific gravity of 1 or more by inserting a rod-like weight 50 into the lower side portion 22 of the cylindrical pole body 20 in order to be independent in the water. Moreover, the specific gravity is set to 1 or less by making the inside of the upper part 21 into a space. In this way, the underwater walking pole 10 has its center of gravity located sufficiently below.
Note that the upper side portion 21 and the lower side portion 22 do not have a clear boundary, and are simply used to distinguish the upper and lower sides of the pole body 20.

As shown in FIG. 2B, the opening of the upper portion 21 of the pole body 20 is sealed with a stopper 61 using an elastic material. The opening of the lower side portion 22 of the pole body 20 is sealed with a sealing material after the weight 50 is inserted, and is fixed by caulking. Alternatively, the weight 50 can be bonded to the inside of the pole body 20 using an adhesive. As the weight 50, for example, a stainless steel round bar can be used.
The weight 50 is not limited to being inserted into the lower side portion 22 but may be attached to the outside or the end portion of the lower side portion 22.

  The upper portion 21 is hollow to make the specific gravity 1 or less. However, the upper part 21 does not necessarily need to be hollow, and can be filled with, for example, polystyrene foam. By adopting the filling configuration, even when water enters the inside of the upper portion 21, the specific gravity can be maintained at 1 or less, and there is no need to perform sealing. That is, the upper part 21 has a specific gravity of 1 or less, and it is only necessary that the specific gravity of the underwater walking pole 10 as a whole can be 1 or less by providing a sufficiently large volume.

  The walking pole 10 left in the water has an overall specific gravity of 1 or less, and therefore can obtain a buoyancy equivalent to the entire gravity. Further, buoyancy greater than gravity acts on the upper portion 21 having a specific gravity of 1 or less, and gravity greater than buoyancy acts on the lower portion 22 having a specific gravity of 1 or more. Therefore, the underwater walking pole 10 floats in a substantially vertical state in water, and the grip portion 30 is positioned in the vicinity of the water surface and becomes independent.

  As shown in FIG. 2C, the weight of the underwater walking pole 10 can be adjusted by making the weight 50 exchangeable. That is, a screw hole 58 is provided at the lower end of the weight 50, and a stopper 62 made of an elastic material is attached with a bolt 71 and a washer 72. The stopper 62 is provided with a mounting hole 63, and the diameter of the stopper 62 is increased by tightening the bolt 71. For this reason, the weight 50 can be fixed to the pole body 20 in a state of providing a sealing property. If the weight is light, it is easy for beginners to use and is suitable for rehabilitation and exercise for middle-aged and elderly people. Moreover, if the weight is adjusted to be heavy, the state is suitable for muscle training.

  3A and 3B show an underwater walking pole 11 which is another example of the present invention. 3A is a schematic view thereof, and FIG. 3B is a cross-sectional view taken along the line AA in FIG. 3A. The underwater walking pole 11 is formed by forming a portion having a large cross-sectional area in the upper portion 21 of the pole body 20 and thereby increasing the buoyancy. For example, when the pole body 20 is formed of a pipe-shaped material, a large-diameter pipe may be used as a part of the upper portion 21.

  By increasing the buoyancy, the grip portion 30 of the underwater walking pole 11 protrudes greatly from the water surface 81 when left underwater. That is, when the length of the grip portion 30 is L1, the length L2 of the protruding portion can be about half of L1. By doing in this way, the underwater walking pole 11 becomes more conspicuous than the underwater walking pole 10, and the grip portion 30 can be visually observed even from a position far away.

  As shown in the cross-sectional view of FIG. 3B, the portion having a large cross-sectional area is not a circular cross section but a flat cross-sectional shape. When the cross-sectional area of the pole body 20 is increased, the resistance of water received when the user walks increases, and the posture of swinging the arm may become unstable. Therefore, the flat cross section is formed by reducing the width W that receives the water resistance so that the water resistance is reduced.

  The pole body 20 having a flat cross section is preferably used together with the directionality with the grip portion 30 having directionality. In other words, in the state of use, it is preferable that the traveling direction of the pole body 20 is determined by the shape of the gripping portion 30, and the width W is the smallest in the traveling direction.

  4A and 4B show an underwater walking pole 12 which is still another example of the present invention. FIG. 4A is a schematic view thereof, and FIG. 4B shows a use state. The underwater walking pole 12 includes a refracting portion 26 at a portion near the grip portion 30 of the pole body 20 and is used together with the grip portion 30 having directivity.

  That is, in the state of use, the traveling direction of the pole body 20 is determined by the shape of the grip portion 30, and the lower portion of the pole body 20, particularly the stone thrusting portion 40, can be formed away from the user. As a result, the stone thrusting portion 40 and the like do not hit the user's leg, and the user can use it without feeling excessive stress. The pole body 20 moves in parallel above and below the refracting portion 26, and the moving distance L <b> 3 is not less than the length corresponding to the outer diameter of the pole body 20.

  By using the underwater walking pole 10 of the present invention, it is possible to easily walk underwater using a general pool. Since it is possible to walk underwater in a stable posture, even middle-aged beginners can easily start walking and continue to do it. And it is possible to easily obtain the rehabilitation effect and the exercise effect of middle-aged and elderly people, and it is also effective as a measure against obesity.
