JPH0965915A - Ferrule of umbrella - Google Patents

Abstract

PROBLEM TO BE SOLVED: To enlarge the area of a ferrule of an umbrella to touch the ground so that it will not slip on the ground by forming the ferrule as a cylinder with a bottom consisting of outer and inner layers, making the outer layer of elastomer and the inner layer of thermoplastic resin. SOLUTION: This ferrule 1 is a cylinder with a bottom and its thick part has two layers; the outer layer 2 and the inner layer 3. The inner layer 3 is made of cheap material which can be easily formed, such as, for example, thermoplastic polypropylene resin or ABS resin. The outer layer 2 is made of rubber which is cheap and has a high binding capacity with thermoplastic resin or thermoplastic elastomer such as ethylene propylene rubber or ethylene propylene diene rubber. The top of the shank of the umbrella is engaged in a hollow part 3a inside this ferrule 1. When the umbrella touches the wet ground or floor, the top of the umbrella touching the ground/floor is sunk because of the elasticity of the outer layer 2 of the ferrule 1, and the area touching the ground is widened, so that the umbrella will not easily slip on the ground.

可塑性エラストマーのエラストマーからなる。Reference numeral 1 denotes a stake attached to the tip of the umbrella,
The butt 1 is a bottomed, substantially cylindrical body, and the thick portion thereof is composed of two layers, an outer layer 2 and an inner layer 3, and the inner layer 3 is inexpensive and has good moldability, for example, a heat treatment of polypropylene resin or ABS resin. The outer layer portion 2 is made of a plastic resin, and the outer layer portion 2 is made of an inexpensive rubber or a thermoplastic elastomer such as ethylene / propylene rubber or ethylene / propylene / diene rubber, which has a good binding property with the thermoplastic resin and is inexpensive.

【００１１】そして前記石突き１をその内孔部３ａにお
いて図２で示す様に傘の先端の傘軸Ａに嵌着する。Then, the pebbles 1 are fitted into the inner shaft portion 3a of the umbrella shaft A at the tip of the umbrella as shown in FIG.
