Description

[Detailed description of the invention] The present invention relates to a method of manufacturing a horseshoe with a cushioning material.

As is well known, horseshoes are worn to protect the hoof, but since the horseshoes used in the past are only made of metal, the impact of landing is directly transmitted to the hoof, causing damage to the hoof and legs. There is a problem with adverse effects on joints, etc.

In view of this problem with conventional horseshoes, the present invention aims to protect the hooves and legs by embedding an elastic cushioning material such as rubber in one or both of the lower and upper surfaces of the horseshoe body to alleviate the impact that occurs when landing. The purpose of the present invention is to provide a hoof and a method for manufacturing the hoof.

In addition, the present invention provides a cushioning material buried in the lower surface of the horseshoe body to improve the grip on the ground when landing, preventing slippage and ensuring a stable landing. It is an object of the present invention to provide a horseshoe that can prevent groove-like wear due to the action of a tightening machine, can be worn for a long period of time, and can effectively prevent damage to the hoof, especially to the lower surface of the heel wall.

Embodiments illustrating the present invention will be described below, and its features will be described in detail. FIG. 1 is a plan view of a horseshoe according to the present invention, FIG. 2 is a bottom view, and reference numeral 1 shows the horseshoe. 2 and 3 show cushioning materials embedded in the lower surface (ground plane) 4 and upper surface 5 of the horseshoe main body, respectively.

As will be described later, the horseshoe main body 1 in the embodiment is molded from an aluminum alloy material, and during molding, recesses 6 and 7 are formed in the lower surface 4 and upper surface 5 for embedding the cushioning materials 2 and 3. It will be done.

The recesses 6, 7 are located on the surfaces 4, 5 as shown in the drawings, particularly in FIG.
A cushioning material 2 which is located in the center of each of the horseshoes and is provided in a groove shape over the entire length along the length direction of the horseshoe body, and each of which is embedded with a substantially dovetail-shaped cross section whose width expands at the bottom. , 3, and furthermore, in this embodiment, recesses 6, 3 provided on the upper and lower surfaces are provided.
Through-holes 8 are bored at appropriate intervals between the bottoms of 7...
Please contact me.

The cushioning materials 2 and 3 are made of a strong material with moderate elasticity and rigidity, such as natural rubber or synthetic rubber, and are embedded over the entire length of the groove-shaped recesses 6 and 7.

This cushioning material may be molded in advance into a shape that matches the shape of the recesses 6, 7 and then embedded in the recesses, but in this embodiment, in order to facilitate manufacturing, the recesses 6, 7 are formed on the upper and lower surfaces. After forming the provided horseshoe body 1, the above-mentioned material is filled in the recess in a molten state and solidified to form the material, and at the same time, the embedding is completed. By advancing the molten material filled from one recess into the other recess through the through hole 8, the cushioning materials on the upper and lower surfaces are integrally connected to each other, and the attachment to the horseshoe body is made firm. .

The cushioning materials 2 and 3 are provided so as to be equally aligned with the respective surfaces 4 and 5, or to be exposed from the surfaces so as to protrude somewhat.

In the drawing, 9 is an iron layer provided on the front edge of the upper surface of the horseshoe body,
10... is a nail hole for attaching the horseshoe body to the hoof;
The iron layer 9 is formed integrally with the horseshoe main body 1 when it is formed by the method described later, and the nail holes 10 are formed at predetermined positions and intervals after the cushioning materials 2 and 3 are attached to the horseshoe main body. The holes are drilled along the center of the horseshoe body.

By the way, in the product of the present invention having the above structure, the horseshoe main body 1 is molded, then the recesses 6 and 7 are provided on the upper and lower surfaces of the horseshoe main body, and the separately molded cushioning materials 2 and 3 are further fitted into the recesses. However, an easier method is to form a recess 6°7 in conjunction with the molding of the horseshoe body, and then fill the recess with a molten cushioning material and allow it to solidify. Yes, and good quality horseshoes can be obtained.

In addition, in manufacturing this, aluminum alloy is used as the material for the horseshoe body, and it is satisfactory in terms of rigidity, and the concave portion 6
, 7, the horseshoe main body in the above embodiment is manufactured from this aluminum alloy.

FIG. 4 shows an aluminum alloy base material 1' that makes up ten horseshoe bodies.The shape of this base material and the order of manufacturing the horseshoes of the present invention from this base material will be explained below. The material is formed into a thick strip by extrusion molding, and groove-shaped recesses 6' and 7', which become the recesses 6 and 7, are formed on the lower surface 4' and upper surface 5' of the material by extrusion molding. It will be set up over the period.

A piece 9' forming the iron layer 9 is integrally provided on one edge (front edge) of the upper surface 5' so as to stand obliquely upward.

This base material is formed as a long material with the above shape, but this base material is then cut to the required dimensions to match the length of the horseshoe, and the base material is placed approximately at the center of the cut length. The above-mentioned piece 9' is attached to the front edge of the upper surface of the base material (indicated by a two-dot chain line), leaving a semicircular portion.

) to form the iron layer 9, and then the recess 6'
, 7', through holes 8 are bored at required intervals to allow the two to communicate with each other.

The base material cut into a predetermined size and made into a unit length of a horseshoe is bent and formed into a well-known horseshoe shape to form a horseshoe body 1, and then each of the base materials is provided on the lower and upper surfaces of the horseshoe body. Recess 6'
, 7', that is, the recesses 6 and 7 are filled with molten synthetic rubber 1
．． This is solidified to form the cushioning material 2.3, and then nail holes 10 are bored at predetermined positions to complete the manufacture of the horseshoe.

The horseshoe manufactured as described above is attached to the underside of the hoof in the same manner as conventional horseshoes, and nails are driven through the nail holes 10.

In this case, as is commonly done in hoof dressing work, the hoof that comes into contact with the upper surface 5 of the horseshoe main body 1 has its circumferential edge touching the upper surface 5.
The outer edge protrudes outward from the periphery of the hoof, and the hoof is placed in such a way that it comes into contact with the cushioning material 3 that is buried in the upper surface of the hoof, so as to be in a position slightly inward from the outer edge of the hoof. After the horseshoe is fitted, the parts are removed with a file so that the outer shape of the horseshoe main body 1 when the hoofing is completed matches the outer shape of the hoof.

As explained above, since the present invention has a cushioning material embedded in the metal horseshoe body, this cushioning material absorbs and cushions the impact that occurs when landing, thereby reducing the impact transmitted to the hoof and legs. This has the great effect of avoiding damage caused by landing impact.

In addition, the cushioning material provided on the underside of the horseshoe body not only cushions the impact, but also securely grips the ground, which prevents the horseshoe from slipping and ensures stable landings and kickoffs. The cushioning material provided on the top prevents the hoof from coming into direct contact with the metal horseshoe body.
Effectively prevents groove-like wear caused by hoof clamp action,
This will prevent damage to the hoof itself.

In the above embodiment, a case was explained in which the cushioning material was buried in the upper and lower surfaces of the horseshoe body 1, but even if the cushioning material was buried in either the lower surface or the upper surface, a cushioning effect at the time of landing can be expected. Of course it can be done.

5 and 6 show the case where cushioning materials 2 and 3 are provided on the lower surface 4 and upper surface 5 of the horseshoe body 1, respectively.
If the cushioning material is provided only on the lower surface, it can absorb and alleviate the impact that occurs between the horseshoe body and the ground when landing, and if the cushioning material is provided on the upper surface, it can absorb and alleviate the impact between the horseshoe body and the hoof.

When a cushioning material is provided on the bottom surface, it improves the engagement with the ground and prevents slipping as described above, while when it is provided on the top surface, it prevents the hoof from collapsing. This means that it can be expected to be effective in preventing damage.

In short, the horseshoes manufactured by the method of the present invention have a resilient and strong cushioning material embedded in either the lower surface or the upper surface of the horseshoe body, or both, so that the impact upon landing is cushioned by this cushioning material. Therefore, the metal material of the horseshoe body, the recesses, and the specific formation of the cushioning material are at the discretion of the manufacturer to the extent that does not deviate from the spirit of the present invention.
