Includes walking stick stone

Abstract

To provide a walking stick having a ferrule at the lower end thereof, which is not easily slippery even on a road surface with a low coefficient of friction. [Solution] This walking stick has a handle 1, a cane shaft 2, and a ferrule 3. The ferrule is made from a mixture of natural and synthetic rubber, and a glass fiber section is provided at the bottom of the ferrule, which is the contact area 6. On road surfaces with a low coefficient of friction, the glass fiber makes the ferrule even less slippery, and on general roads with a high coefficient of friction, the contact area of ​​the ferrule ensures stability when walking.

Description

[Technical Field]

[0001] This invention relates to a ferrule for a walking stick that is attached to the bottom end of a walking stick or the like to protect the bottom end of the walking stick and provide an anti-slip effect on road surfaces with a low coefficient of friction, such as frozen roads. [Background technology]

[0002] Conventional walking sticks have a ferrule for a walking stick of the shape described in Patent Document 1 at the bottom end of the walking stick or the like. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Design Registration No. 1682652 [Patent Document 2] Utility Model Registration No. 3182054 [Patent Document 3] Patent Publication No. 2008-272421 Summary of the Invention [Problem to be solved by the invention]

[0004] Conventional walking sticks have a ferrule shaped like that described in Patent Document 1, and by using ferrules such as those described in Patent Documents 2 and 3 to protect the lower end of the walking stick, they have an anti-slip effect on frozen roads, etc. However, when using the ferrule for walking sticks described in Patent Document 1 and configured as described in Patent Documents 2 and 3, the coefficient of friction is low on icy roads, and the ferrule for walking sticks often slips, hindering walking. Therefore, the object of this invention is to provide a walking stick with a ferrule at the bottom that does not interfere with walking on icy or normal road surfaces. [Means for solving the problem]

[0005] According to this invention, there is provided a ferrule for a walking stick that is attached to the lower end of the walking stick to protect the lower end of the walking stick, the ferrule being made of a mixture of natural rubber and synthetic rubber, and the bottom surface of the ferrule further comprising a glass fiber member. [Effects of the Invention]

[0006] According to the invention of claim 1, a ferrule for a walking stick is provided that is attached to the lower end of the walking stick to protect the lower end of the walking stick, and is made of a mixture of natural rubber and synthetic rubber, and the bottom surface of the ferrule further comprises a glass fiber member, making it possible to provide a ferrule for a walking stick that does not interfere with walking on icy roads or normal road surfaces. [Brief explanation of the drawings]

[0007] [Figure 1] This is a walking stick with a ferrule according to the present invention. [Figure 2] This is a walking stick with a ferrule according to the present invention. [Figure 3] 1 shows the structure of the bottom part for a walking stick with a ferrule according to the present invention. DETAILED DESCRIPTION OF THE INVENTION

[0008] The cane with a ferrule according to the present invention will be explained with reference to the accompanying drawings. [Example]

[0009] FIG. 1 is a front view of a cane stand for a cane with a ferrule according to the present invention. The structure of the cane, which is composed of a cane shaft 2 connecting a cane handle 1 and a ferrule 3 on the ground surface, is disclosed in Patent Document 2. and the same structure as that of Patent Document 3. In this invention, the ferrule 3 is made of a mixture of natural rubber and artificial rubber, and the ferrule 3 Glass fiber material is further mixed into the bottom contact portion 6 that comes into contact with the ground. Generally, natural rubber has excellent elasticity, extensibility, adhesive properties, and is highly resistant to abrasion and breakage, but when used for cane tips, the high elasticity of the tip means that it does not have a good affinity with the ground. Therefore, by mixing synthetic rubber into the tip material, the strength of the tip can be increased, thereby improving the affinity of the tip with the ground. Styrene-butadiene rubber (SBR) is a typical synthetic rubber, and has excellent abrasion resistance and aging resistance. In this invention, the ferrule 3 is made from a mixture of natural and artificial rubber, which improves the moldability of the ferrule 3 and allows it to deform like a shoe, whether it is thrust vertically into the ground as in Figure 1 or diagonally forward as in Figure 2, providing a high level of anti-slip performance.The elasticity of the upper part of the ferrule 4 makes it easy to walk on both icy and normal road surfaces.

[0010] Figure 3 is a bottom view of the lower ferrule (5) of the present invention, showing the area where the bottom contact surface (6) made of a mixture of glass fiber and the ground surface comes into contact with the ground. The bottom contact surface (6) is made of multiple wavy rubber elements, a mixture of natural rubber, artificial rubber, and glass fiber. Furthermore, grooves of approximately 2 mm are formed between adjacent wavy rubber elements. By providing the bottom contact portion 6 having a glass fiber member, the glass fiber of the ferrule lower portion 5 comes into contact with the road surface almost perpendicularly in a spike-like state. These glass fiber spikes provide anti-slip properties on frozen surfaces due to the scratching effect of the glass fibers, but are harder than glass fibers found in mirror-finish ceramic tiles that have the same hardness as tempered glass. On wet floors, when a load of approximately 1 Newton is applied, the microscopic glass fiber spikes retract and transform into rubber with strong adhesive friction, providing anti-slip properties. This anti-slip property is achieved by utilizing the flexibility unique to the natural rubber base. This phenomenon is thought to be a dewetting phenomenon in which an energetically unstable thin liquid film stabilizes; when the thin liquid film stabilizes from an unstable state, the droplets separate and contract, preventing the formation of a water film on road surfaces with a low coefficient of friction, thereby providing anti-slip properties and preventing the ferrule 3 from slipping. Regarding the material composition, the base rubber is natural rubber with synthetic rubber (SBR) added to adjust the hardness, with the composition ratio being in the 80% range, and the rubber to glass fiber composition being 30-40% glass fiber.
