Description

Underwater walking pole

The present invention relates to an underwater walking pole that assists walking in water, and more particularly to an underwater walking pole that is easy for a middle-aged beginner to be familiar with and can easily tackle, and that can also be used as an aid for stretching exercises.

Conventionally, underwater walking movements have been actively performed in pools. 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 beginners to perform for a certain period of 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. This 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.
Patent Document 2 proposes a personal underwater walking apparatus that can perform underwater walking alone.

However, the installation of equipment for underwater walking, which is different from a normal pool, is expensive and 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.

JP 7-259363 A JP-A-8-206251

The inventors of the present invention have made trials and practical tests of underwater walking poles based on the experience of manufacturing ski poles and land walking poles for many years.

An object of the present invention is to provide an underwater walking pole that is easy for a middle-aged beginner to get close to and can easily start underwater walking. And it is to make underwater walking as easy as walking, so that it is attractive to continue walking. Another object is to use a pole that can be used as an auxiliary tool for stretching exercises.

In order to achieve the above object, the present invention is an underwater walking pole for assisting walking in water, and is provided with gripping portions at both ends of a cylindrical pole body. It is a feature.

And both the said holding parts can be set as the structure which is the same material and is provided with the same shape.
Moreover, the said holding part and the said pole main body can be set as the structure provided with the same axis line.

When the walking pole is positioned underwater without being constrained, the walking pole can be positioned in a horizontal state in the vicinity of the water surface.
Moreover, when it is located in water without being restrained, it can be set as the structure which a part of said pole main body is located above a water surface.

Also, the pole body may have a shape in which the outer diameters at both ends are narrower than the other parts.

Moreover, the said holding part can be set as the structure provided with the cylindrical holding | maintenance main part which a user hold | grips, the holding bottom part to which a little finger contacts, and the holding top part to which an index finger contacts.
Moreover, all the cross sections orthogonal to the axis line of the said holding | grip part can be set as the structure which is circular.

Moreover, the upper surface of the said grip bottom part can be set as the structure formed in the concave surface.
Further, the gripping part may be configured to include a constricted part between the gripping main body part and the gripping top part.

The underwater walking pole of the present invention includes gripping portions at both ends of a cylindrical pole body.
For this reason, it is safe to use it in the water where there are many people in swimsuits, and both the users themselves and those around them can devote themselves to their own exercises with peace of mind.
In other words, it is possible to freely walk underwater using two poles and to perform stretching exercises with one pole held horizontally.

And, by using an underwater walking pole with grips at both ends, it becomes possible to add an excellent configuration as shown below, and even middle-aged beginners can use it freely and randomly.

That is, by making the two gripping portions the same material and the same shape, it is possible to walk underwater with the same sensation regardless of which one is gripped.
Further, since the two gripping portions and the pole main body are provided with the same axis, it can be made easier to use.

For example, when performing underwater walking or stretching exercises under the instructor, the user may simply hold any one of the gripping portions, and does not need to care about the gripping position or direction.
Therefore, middle-aged beginners are easy to get close to and can easily start walking underwater.
However, it can be used for advanced users by slightly bending both sides of the pole body to give directionality.

Further, the underwater walking pole can be configured to be positioned in a horizontal state in the vicinity of the water surface when placed underwater without being constrained, that is, when left underwater. Thereby, loss in the pool can be prevented.
In addition, since a part of the pole main body is positioned above the water surface in water, it can be recognized from a distance, which makes it easier to find.

The pole body may have a configuration in which the outer diameters at both ends are narrower than the other parts. For this reason, it becomes easy to insert the end part of the pole body into the grip part and to integrate them.
Moreover, since it becomes possible to enlarge the outer diameter of another part, the resistance force in water can be enlarged. Further, the buoyancy can be increased, and the portion located above the water surface can be increased.

By increasing the resistance in water and walking underwater, muscles around the wrist and upper arm will be trained. That is, the force to hold the pole in the water against the buoyancy is required, and the muscles around the wrist are trained. Further, in order to advance the pole forward underwater, it is necessary to have a force to move forward against the resistance of water, and to train muscles around the upper arm.

The gripping portion may be configured to include a cylindrical gripping main body portion gripped by the user, a gripping bottom portion with which the little finger abuts, and a gripping top portion with which the index finger abuts. This makes it possible to obtain a soft and stable grip even when gripping without any effort.

The gripping part can be configured such that the cross section perpendicular to the axis is all circular. Thereby, the directionality at the time of gripping is completely eliminated, and the gripping can be performed easily.

The upper surface of the grip bottom (the surface on which the little finger abuts) can be configured to be concave. This makes it possible to obtain a softer and more stable grip.

The grip portion can be configured to include a constricted portion between the grip body portion and the grip top portion. This increases flexibility when the gripping portion functions as a stone thrusting portion and enables soft grounding, so that it is possible to walk underwater for a long time without damaging the wrist or elbow.

Further, in the case of walking underwater, the durability of the stone thrusting part is important. However, since both gripping parts are used as the stone thrusting part, the durability is doubled.
Further, by increasing the flexibility of the gripping part, walking exercise can be performed without damaging the floor surface in an indoor corridor or the like.

The present invention can be used as an assisting device for underwater walking and stretching exercises, and is superior in all respects, such as purchase costs, utilization efficiency, and storage location, compared to the case of using different assisting devices. become.

FIG. 1 is a schematic view showing an example of an underwater walking pole. FIG. 2-A shows a state when the underwater walking pole of FIG. 1 is located underwater. FIG. 2-B is a partially enlarged view of FIG. 2-A. FIG. 3 is a schematic view showing another example of the underwater walking pole. FIG. 4-A shows a state where the underwater walking pole of FIG. 3 is located in the water. FIG. 4-B is a partially enlarged view of FIG. 4-A. FIG. 5 is a schematic view showing a grip portion of the underwater walking pole of FIG.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic view of an underwater walking pole 10 which is an example of the present embodiment, and shows a vertical state when used in walking. The underwater walking pole 10 is a pair of two, and walks with one in both hands.

The underwater walking pole 10 is characterized in that

grip portions

30 and 30 are provided at both

end portions

21 and 21 of a cylindrical pole body 20, respectively.
For this reason, it can be safely used even in a normal pool. Moreover, when walking, the grip part 30 on either side may be gripped, and even a middle-aged beginner can use it without any effort. Moreover, by this, in addition to the original use which assists walking in water, it can be used also as an auxiliary | assistance tool of stretch exercises.

Both the upper and lower

gripping portions

30 and 30 can be made of different materials and different shapes to change the feel when gripped. However, it is preferable for middle and old beginners to use the same material and the same shape. This is because it can be handled more easily if it can be used casually, rather than selecting either one.

Moreover, it is preferable that both the holding

parts

30 and 30 and the pole main body 20 are provided with the same axis line. In other words, considering the central axis of each gripping part 30, it is preferable that the extension line coincides with the central axis of the pole body 20.

The lower gripping portion 30 has a tip 34 at the tip 34. By making each axis line the same axis line, it becomes easier for the upper gripping portion 30 to grasp the feeling that the lower gripping portion 30 (stone thrust portion) catches the floor surface. And even if the pole main body 20 is formed thick and the resistance of water is increased, walking in water can be facilitated.

FIG. 2-A shows a state where the underwater walking pole 10 is located in the water without being constrained, and FIG. 2-B shows an enlarged part thereof.

The underwater walking pole 10 can be positioned in a horizontal state near the water surface WL when left underwater. That is, the underwater walking pole 10 can be positioned in the vicinity of the water surface WL if manufactured so that the overall specific gravity is 1 or less, and if manufactured so that the entire center of gravity is the center of the pole body 20, It is possible to be located at.

Further, when the underwater walking pole 10 is positioned underwater without being restrained, a part of the pole body 20 can be positioned above the water surface WL.
When the outer diameter of the pole body 20 is relatively small and the outer diameter of the grip portion 30 is relatively large, such as the underwater walking pole 10, it is necessary to manufacture the entire specific gravity to be about 0.75 or less. is there.

Returning to FIG. 1, the grip 30 of the underwater walking pole 10 will be described.
The gripping part 30 includes a cylindrical gripping main body part 31 that the user grips, a gripping bottom part 32 on which the user's little finger abuts, and a gripping top part 33 on which the user's index finger abuts.
As described above, the distal end 34 of the grip portion 30 is projected to form a stone thrust portion.

The grip portion 30 is manufactured so that the cross section perpendicular to the axis is all circular.
That is, the three-dimensional shape of the underwater walking pole 10 is a rotating body centered on the axis in FIG. 1, and the same holds for the grip portion 30.
For this reason, when grasping the grasping part 30, it is not necessary to rotate around the axis to determine the direction, and the object can always be grasped with a constant feeling by simply grasping it.

FIG. 3 shows a schematic view of an underwater walking pole 11 as another example of the present embodiment in a vertical state. The underwater walking pole 11 is different in shape from the underwater walking pole 10 in each part.
The underwater walking pole 11 is a pair of two, and walks with one in both hands.

The underwater walking pole 11 includes gripping

portions

30 and 30 at both

end portions

Both the upper and lower

gripping portions

Moreover, it is preferable that both the holding

parts

In the underwater walking, the lower grip 30 is a stone bump. By making each axis line the same axis line, it becomes easier for the upper gripping portion 30 to grasp the feeling that the lower gripping portion 30 (stone thrust portion) catches the floor surface. And even if the pole main body 20 is formed thick and the resistance of water is increased, walking in water can be facilitated.

The pole body 20 is formed such that the outer diameters of both

end portions

21 and 21 are narrower than other portions.
For this reason, it becomes easy to insert the end part 21 of the pole main body 20 into the holding part 30, and to integrate. Moreover, while increasing the outer diameter of parts other than both ends 21 and 21, the buoyancy can be increased, and the resistance force in water can be increased.

FIG. 4-A shows a state where the underwater walking pole 11 is positioned in the water without being constrained, and FIG. 4-B shows an enlarged part thereof.

The underwater walking pole 11 can be positioned in a horizontal state near the water surface WL when left underwater. That is, it is easy to make the whole specific gravity 1 or less than the underwater walking pole 10 and to make the whole center of gravity the center of the pole body 20 easier.

And by increasing the buoyancy, the specific gravity of the whole can be easily reduced to 0.5 or less as well as to 0.75 or less. Thereby, about half of the pole body 20 can be positioned above the water surface WL. In this state, it is possible to recognize the own underwater walking pole 11 even from a distance, so that it is not lost.

Moreover, the underwater walking pole 11 can be used as a tool for strengthening muscular strength, not just an underwater walking aid, by increasing the resistance in water.
That is, a force to hold the entire underwater walking pole 11 underwater against the buoyancy is required, and muscles around the wrist are trained. Further, in order to advance the underwater walking pole 11 forward, a force to move forward against the resistance of water is required, and muscles around the upper arm are trained.

FIG. 5 shows an enlarged cross-sectional view of the grip portion 30 shown in FIG.
The grip portion 30 includes a cylindrical end main body portion 31 that the user grips, a grip bottom portion 32 on which the user's little finger abuts, and a grip top portion 33 on which the user's index finger abuts.
Moreover, the front-end | tip of the holding part 30 located in the lower part forms a stone thrust part.

The grip portion 30 is manufactured so that the cross section perpendicular to the axis is all circular.
That is, the three-dimensional shape of the underwater walking pole 11 is a rotating body centered on the axis in FIG. 3, and the same holds for the grip portion 30.
For this reason, when grasping the grasping part 30, it is not necessary to rotate around the axis to determine the direction, and the object can be always grasped with a constant feeling simply by grasping it.

The upper surface 36 (the surface on which the little finger abuts) of the grip bottom portion 32 is formed as a concave surface. For this reason, when grasped, the little finger and the palm are wrapped in the upper surface 36, and a soft and stable grip feel can be obtained.

Further, a constricted portion 35 is formed between the grip main body portion 31 and the grip top portion 33. For this reason, the peripheral edge of the grip top 33 is easily deformed up and down.
Therefore, when the index finger comes into contact with the gripper, the peripheral edge portion is deformed upward, and a soft grip feel can be obtained.

In addition, the grip top portion 33 of the grip portion 30 located on the lower side functions as a stone thrusting portion during underwater walking. Will be deformed. As a result, soft grounding is possible, and long-time underwater walking can be performed without hurting the wrist or elbow.

The

underwater walking poles

10 and 11 can be used as an aid for stretching exercises in addition to the original use of assisting walking in water. Gymnastics can be performed underwater or on the floor in the home.

Stretching exercises performed by holding the

underwater walking poles

10 and 11 in both hands can be performed on land or in water, similar to the exercises conventionally performed using walking poles or ski poles on land.

The

underwater walking poles

10 and 11 can perform stretch exercises using only one on land or in water.
At this time, the relationship between both hands and both gripping portions 30 is opposite to the case of walking, in which the user's index finger contacts the grip bottom portion 32 and the user's little finger contacts the grip top portion 33.

And while holding both the gripping parts 30 with both hands, it is in a state where it is raised above the head, a state where it is positioned behind the neck, or a state where it is positioned behind the waist be able to.
In these states, it is possible to stretch by tilting the upper body back and forth, tilting left and right, and twisting left and right.

The embodiments of the present invention have been described in detail above with reference to the drawings. However, the specific configuration is not limited to these embodiments, and design changes that do not depart from the gist of the present invention are not limited thereto. Included in the invention.
In particular, as the user becomes more skilled, it is necessary to have a directional aspect or a heavy aspect, and various modifications are possible.
For example, the aspect which makes the cross section of the pole main body 20 or the holding part 30 an ellipse can be considered. Moreover, the

end parts

21 and 21 of the pole main body 20 are bent a little, and the aspect which the pole main body 20 does not have a fixed axis line can be considered. All of these embodiments modified for advanced users are also included in the present invention.

By using the underwater walking pole 10 of the present invention, it is possible to easily perform underwater walking using a general pool. Since it is only necessary to grip the grip portion 30 in a casual manner, even a middle-aged beginner can easily start and can continue. 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.
