Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a reinforced strength stock and a grounding component thereof.

[0002]

[Prior art]

 Dumbbells, expanders, and the like are known as exercise equipment for strengthening arms.

[0003]

[Problems to be solved by the device]

 Most of the conventional strength-enhancing exercise devices are intended to be used indoors, and most of them have been designed to strengthen the muscular strength of the arm by exercising while standing upright, for example. An object of the present invention is to provide an inexpensive and simple arm strength strengthening stock and a grounding component for the arm strengthening arm muscles mainly for outdoor walking exercises.

[0004]

[Means for Solving the Problems]

 The arm strength reinforced stock of the present invention has, as a basic structure, a shaft, a grip provided at an upper end portion of the shaft, and a grounding portion made of an elastic body provided at a lower end portion of the shaft. However, the ground contact portion is provided with a ground contact surface that is at least larger than the cross-sectional area of the shaft.

In addition, the grounding component for the arm strength stock of the present invention has, as a basic structure, an elastic body, a hole for receiving the tip of the shaft on the upper surface, and a grounding surface on the lower surface. However, the ground contact surface is larger than the opening area of the hole.

[0006]

[Action]

 The strength-enhancing stock of the present invention is used by holding the grip with a hand and holding a stock in one or both hands. That is, when walking, the user swings his arm from the front to the rear by the side of his body in accordance with the movement of his legs, attaches the ground contact part of the stock to the ground in front, and keeps his arm pressed while pushing the ground. The action of sending it backward and kicking the ground is repeated for each walking step. This can strengthen the arm muscles. At the same time, the force of kicking the ground with the legs adds the force of kicking the ground with the arms, increasing the reaction force and doubling the walking speed. Since the ground contact surface is larger than the cross-sectional area of the shaft, it is less likely to slip between the ground contact surface of the stock and the ground, compared to grounding with a small cross-sectional area of the shaft like a normal cane, and the stock from the arm The force applied to effectively produces a reaction force without waste. Also, because the grounding part is made of an elastic body, while the arm is being sent from the front to the back while pressing the grounding part against the ground, the grounding part is flexibly deformed to ensure a sufficient grounding area and to secure the contact of the stock. Sliding between the ground is less likely to occur.

The overall shape of the ground contact portion is not particularly limited, but in order to ensure the slip prevention of the stock, it is preferable to use a long ground contact surface such as a rectangle in the front and rear. In order to effectively bend and deform the ground contact portion, it is desirable to form a recess in the intermediate portion sandwiched between the front end portion and the rear end portion of the ground contact surface. According to this, the concave portion acts like the arch of a person's foot, effectively flexing and deforming the ground contact portion, and the ground contact surface follows the vibration of the stock to make sure contact with the ground. In order to make the ground contact surface less slippery, depending on the condition of the ground surface, for example, when moving on grassland, in the front-back direction at the middle part sandwiched between the front end and the rear end of the ground contact surface. It is also possible to provide an undulating sawtooth-like shape so that the sawtooth can bite the grass. Further, a slip-prevention groove may be formed in a portion which comes into direct contact with the ground like an automobile tire.

[0008] The grip is preferably continuous from the upper end of the shaft to the middle part so as to cope with the height difference of the user. If the grip is formed separately from the shaft and can be connected, the grip can be replaced.

The shaft can be made of any material such as steel, light alloys and the like. Further, it is desirable that the weight or balance can be appropriately selected according to the user's physical strength or physical strength. Therefore, the shaft and the grounding portion may be detachable. Various modes are conceivable as a configuration example in which the shaft and the grounding part can be attached and detached, but the simplest configuration is that the shaft and the grounding part are configured separately and a hole is formed on the upper surface of the grounding component. It is necessary to insert the tip of the shaft into this hole. In this case, a single grounding component may be provided with a plurality of holes having different sizes and shapes so that a walking stick, ski pole, etc. can be used as a shaft.

The ground component has two thick main surfaces, three side surfaces, and three top surfaces by cutting out the vertices of each triangle of a triangular plate material having a thickness. All of them can be used as a ground plane. In this case, it is necessary to provide a shaft insertion hole on each top surface. When there are two or more ground planes, if the ground planes have different shapes as described above, it is possible to select and use a ground plane having a shape corresponding to the ground condition. If the diameters of the holes are made different, shafts having different diameters can be appropriately selected and used, and canes, ski poles, etc. can be used as the shafts.
