Abstract

To provide a fall prevention tool for a cane, a tool that improves handleability of a user.SOLUTION: The fall prevention tool for a cane has a plurality of blade-shaped members 4 which are installed with equal spaces apart on the outer peripheral surface of a cylindrical part 5. The tool prevents the cane from slipping down and falling by friction between an object to lean the cane against and the blade-shaped members 4. By a roughly stream-lined shape and the hardness of a material, the blade-shaped members 4 are deformed to increase the friction, thereby suppressing slipping down and falling of the cane. The plurality of blade-shaped members 4 installed with equal spaces apart on the outer peripheral surface of the cylindrical part 5 facilitate grip by expanding a gap between the body frame and a surface when the cane is placed flat.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a cane fall prevention tool attached to a cane for assisting walking.

  When a typical cane user leaves the cane, there are methods such as leaning on the corner of a wall, desk or chair, hooking the grip on the corner of the desk or chair, or placing it flat on the ground. The general cane shown in FIG. 2 is provided with a grip 1 that is gripped by a user and a stone protrusion 3 that contacts the main body frame 2. When a cane is left to stand temporarily, it is often leaned against a wall, a desk, or a chair corner with the cane tilted in order to make it easier to hold it at the next use and to avoid the danger of itching.

If there is no suitable object to be hooked or stood, leave it flat on a desk, floor, seat, or other flat surface.

When standing against a wall, it tries to suppress the fall by the frictional force between the grip 1 that touches the wall and the wall. However, since the frictional force is small, the fall is often weak against peristalsis.

As shown in FIG. 3, when standing and standing using the corners of a desk or chair, the surface of the main body frame may be coated although it tries to suppress slipping by the frictional force between the main body frame 2 and the object. Many of them have low frictional force, so they are weak against sliding and often slide down.

In addition, when left on a flat surface such as a floor surface or a seating surface, as shown in FIG. 4, the grip 1 and the stone protrusion 3 serve as a contact point with the flat surface, and the gap between the main body frame 2 and the flat surface is narrow. There was a problem that it was difficult to grasp when picking up.

Japanese Patent Application Laid-Open No. 2008-295989 discloses a conventional tipping prevention tool in which a protrusion having an adhesive portion provided on the lower surface is attached to the main body frame 2, and the object and the stick are brought into close contact with each other by the adhesive force and the weight of the main body to prevent the tipping over. However, it is difficult to use because the height of the object is limited because it cannot be attached below the center of gravity, or the position of the tool needs to be adjusted, and JP 2003-102525 uses rubber on the entire surface of the cane. Although it is intended to prevent overturning by sticking with tape, it is difficult to use due to its small contact area with the object and low frictional force and difficulty in mounting.

  At present, it is easy to grip a cane that is placed flat on a flat surface such as a floor surface or a seat surface by using a friction force with an object that contacts a main body frame by tilting a general cane and preventing slipping off. Tools that have a function that can be used are not widespread. Therefore, the present invention has the above-mentioned functions to increase the choice of the cane place, reduce the psychological stress of getting lost in the place of the user, and facilitate the picking up of the cane that is placed flat or falls down. The purpose is to improve the convenience of walking sticks.

In order to solve the above-described problems, the present invention is a cane fall prevention device characterized in that a resilient resin is used as a material and a plurality of blade-like members are provided on the outer peripheral surface of a cylinder.
The blade-shaped member is a cane tipping prevention device characterized in that one end is narrow and the other end is substantially streamlined.
Furthermore, the blade member is an overturn prevention device, wherein the blade members are arranged at equal intervals on the outer peripheral surface of the cylinder.

  According to the present invention, at least one of the plurality of blade-like members provided on the outer peripheral surface of the cylindrical portion comes into contact with an object such as a desk or a chair and is deformed by the weight of the cane, thereby increasing the contact area and causing friction. When the user temporarily leaves the cane because the coefficient increases, slipping is suppressed and the cane is kept in a stable state, the cane is left standing on a desk or chair with various heights. Can do.

  In addition, users of general walking aids often have problems with their lower limbs, and bending and squatting are physically burdensome. For this reason, when the user temporarily leaves the cane, he always uses his nerves to fall the cane and has a fear of giving anxiety to the surroundings due to the sound of the fall. The effect eliminates anxiety about falls and reduces psychological stress.

  In addition, when the user picks up a cane that is placed flat on the floor surface or falls down, according to the present invention, the gap between the main body frame and the floor surface is widened by 5 to 8 mm compared to non-wearing, so that the user can easily insert a finger. The physical burden can be reduced by shortening the time required for the gripping.

  Further, when the user of the cane sits down and holds the cane, the frictional force between the hand and the substantially streamlined wing-shaped member that is provided in plural in all directions and is easy to grip increases and the cane slips down. And can prevent falls.

  Further, when a user of a cane is used in combination with a wheelchair, the cane is often sandwiched and held between both lower limbs when the wheelchair is used, but a plurality of substantially streamlined blades provided in all directions according to the present invention By increasing the frictional force between the lower limbs with the shaped member, the cane can be prevented from slipping or falling.

  The convenience of a general walking aid cane can be improved by the cane fall-preventing device according to claims 1, 2, and 3 of the present invention.
