Abstract

PROBLEM TO BE SOLVED: To provide a stick as a walking assistant, by which the fatigue of the wrist can be reduced for weak old or sick person. SOLUTION: A position of the center of gravity A of a stick 12 is close to a grip by more than 70% from a point of the ferrule 4, so that the moment of inertia is remarkably reduced in comparison with that of a conventional stick, when the stick is shaked around the grip 3 as a fulcrum. Thereby the fatigue of the wrist can be reduced even when a person uses the stick 1 for a long time. As a means for realizing the stick, a rod part 2 of the stick 1 is manufactured by a filament winding method while using the carbon fiber and epoxy resin as the material. The total weight of the stick 1 is preferably not more than 150g.

2. Description of the Related Art Conventionally, as a general configuration of a walking stick commercially available as a walking aid, a grip is set at one end of a rod-shaped portion, and a ram is set at the other end. There are various types of rods, such as wooden, metal, and plastic. When the position of the center of gravity is measured, the rod is uniformly at a gripping position of about 60% of the entire length from the tip of the butt. See Table 1).

In the case where a weak or elderly person or a sick person uses a walking stick as a walking aid and walks for a long time, it is better that the wrist holding the walking stick has less burden. As a means of reducing the burden on the wrist, it is of course to reduce the weight, but it is important to reduce the moment of inertia when swinging around the grip portion. Since the moment of inertia is obtained by multiplying the total weight by the distance from the fulcrum to the center of gravity, in order to reduce this, it is important to reduce the distance from the fulcrum to the center of gravity.

By reducing the weight of the bar, not only the overall weight is reduced, but if the members and structure of the grip are considered the same as the conventional product, the lighter the bar, the more the center of gravity will be located on the grip side. Stop by. As a result, the distance from the grip to the center of gravity with the fulcrum as a fulcrum is reduced, and the moment of inertia is significantly reduced in combination with the weight reduction effect.

The total weight of commercially available walking sticks is 17
It is about 0 g to 250 g, and the position of the center of gravity is about 60% of the total length from the tip of the butt. In contrast,
The stick made by the filament winding method using the carbon fiber of the present invention has a total weight of about 125 gr.
The weight ratio is 74% lighter than the lightest walking stick of the conventional product. In addition, the position of the center of gravity has moved significantly closer, and the position has been closer to about 80% of the total length. As a result, when the moment of inertia was calculated using the grip position as a fulcrum for a walking stick having a total length of about 85 cm, it was reduced to about 40% of a commercially available product. Therefore, when swinging around the grip, the burden on the wrist was greatly reduced.
