Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION The present invention is applied to the bottom of the heel of a shoe, particularly,
The bottom of the high-heeled heel for ladies an improvement of install them top lift.

[0002]

2. Description of the Related Art A conventional top lift of this type is
There are roughly two types. One is that a disc at one end of the pin to be fitted in the bottom of the heel of the shoe is surrounded aluminum formed integrally with the metallic core material such as iron outside body made of hard resin, The other one is that the disc of the core material is surrounded by an outer body made of a soft resin.

[0003]

[Problems to be Solved by the Invention] By the way, the above-mentioned 1
One eye In the top lift, since the outer body is made of hard resin, since the integration of the core material takes place firmly, with Kunar such that the outer body or detached from the core material Although that have a advantage of excellent wear resistance, and they happen to wet road surface, and has a risk of such injury and slippery.

[0004] Further, in the second top lift described above, since the outer member is made of soft resin, but that have a advantage that hardly slipping large frictional resistance between the road surface, and the core and has a outer member is liable to leave against core material weak integral strength between the outer member, there is a problem that abrasion resistance is also inferior.

The present invention is intended to solve the above-mentioned problems, and its purpose is to interpose a core material and a core material.
The possibility of withdrawal of the outer member is rather name Ru frictional resistance Ah is provided a large have difficulty sliding top lift <br/> between the road surface.

Another object of the present invention is to:
The protrusion of the core material made of hard resin is exposed from the outer material made of soft resin
By doing so, it is possible to improve the wear resistance of the external material.
It is possible, appropriate frictional resistance obtained, further, if the outer member is worn, since the core material is out collision from the outer member, to provide a top lift that can be quickly determine replacement timing of the outer member
It is something .

[0007]

Means for Solving the Problems The present invention top lift is for St achieve the object, one end of the pin to be fitted in the bottom of the heel of the shoe, is a disc having a plurality of holes and metallic steel core which is integrally formed, surrounding said circular plate of the core material, a hard resinous core material respectively on the upper and lower surfaces to have a plurality of projections, soft surrounding the core material It consists of a resin outer material, and the protrusions on the top and bottom surfaces of the core material
It is exposed from outside materials.

[0008]

Embodiments of the top lift according to the present invention will be described below with reference to the drawings. 1 to 3 show a method of manufacturing a top lift of an embodiment, in FIG. 1, 1 is aluminum, indicates core material formed of a metal such as iron, a pin 1a whose tip is formed in acute angle form , One end of the pin 1a, that is,
The opposite end the acute-angled portion is constituted by a disc 1b having a plurality of holes 1b ₁ which is integrally formed.

The core material 1 thus constructed is surrounded by a hard resin such as thermoplastic polyurethane elastomer E564 or E568 (manufactured by Nippon Miractolan Co., Ltd.) by means such as a mold as shown in FIG. .
As a result, a part of the pin 1a and the entire disc 1b are surrounded by the hard resin, and a part of the pin 1a and the disc 1b are surrounded.
The formed part becomes the core material 2.

At the time of molding, this core material 2 enters into the hole 1b _{1 of the} disc 1b and is firmly integrated with the core material 1. A plurality of protrusions 2a and 2b (six pieces each) are formed on the upper and lower surfaces of the core material 2 during molding.

In this way, the core material 2 surrounding the core material 1
By means of molding or the like as shown in FIG. 3, for example, thermoplastic polyurethane elastomer E59.
The outer material 3 is surrounded by a soft resin such as 0 (manufactured by Nippon Miractolan Co., Ltd.) and the core material 2 is surrounded . At this time,
Protrusion 2a of the lower faces of the core material 2 so as to expose the 2b, forming the outer member 3. Needless to say, the outer material 3 has the same shape as the heel bottom of the shoe.

In the top lift constructed as described above, the core material 1 fitted and fixed to the heel bottom of the shoe is surrounded by the core material 2 made of hard resin, so that the core material 1 and the core material 2 are /> becomes rigid, no Rukoto the core material 2 is Dassu away from the core 1, moreover, the core material 2, the upper and lower surfaces projections 2a, 2b
Since the outer material 3 is exposed and surrounded by the outer material 3 made of a soft resin, the outer material 3 does not separate from the large core material 2,
Therefore, replacement of the top lift due to breakage is almost eliminated , and since the outer material 3 is made of soft resin, friction resistance with the road surface is large and it is difficult to slip.

[0013] Then, expose the projections 2b from the lower surface of the outer member 3
By causing, while maintaining the magnitude of the frictional resistance of the road surface, the wear due to friction with the road surface of the outer member 3 is soft resin is thus reduced to the protrusion 2 b is a hard resin, the outer member 3
It can improve wear resistance and moderate friction.
Resistance is also obtained, and if the outer material wears out, the core material 2
Since it protrudes from the outer material 3, it is possible to replace the outer material quickly.
It can be judged .

[0014]

[Effect of the invention The present invention, as described above, the core material surrounding the core material made of hard resin, the core material, the upper and lower surfaces projections
2a, by which expose the 2b and surrounded by the outer member made of soft resin, a possibility of withdrawal of the outer member relative to the core material is such Kunar and <br/> both difficulty potatoes slipping large frictional resistance between the road surface So
Oh Ru.

[0015] In addition, it provided on the lower surface of the hard resin of the core material
By Rukoto the projection is out Ritsuyu by imported timber made of soft resin, road
While maintaining the amount of frictional resistance with the surface,
Abrasion due to friction can be reduced by the protrusions, the wear resistance of the outer material can be improved, moderate friction resistance can be obtained , and if the outer material is worn, the core material is
Since al projecting a shall be quickly determine replacement timing of the outer member.
