Description

[Detailed description of the invention] [Industrial application field] The present invention relates to horseshoes.

[Conventional Technique #] In order to protect the hooves, horseshoes are widely worn on the hooves of horses, regardless of whether they are used for cargo handling or horseback riding, and horseshoes made only of iron have been used for a long time.

Horseshoes made of iron are rigid and have no shock absorbing properties, so it is no exaggeration to say that they are used exclusively to protect the hoof from wear and direct damage.

In view of these defects in iron horseshoes, various attempts have been made, such as pasting elastic cushioning materials such as rubber on the underside of the horseshoes, and covering the horseshoes themselves with elastic materials to absorb the impact when they land. However, none of these examples have been put into practical use because they lack durability, such as the difficulty in fixing the cushioning material to the horseshoe body and the cushioning material easily coming off due to a strong impact when landing.

In view of the above-mentioned circumstances, the present invention has developed a highly durable horseshoe having a shock-absorbing portion on the lower surface of the horseshoe body, which was first disclosed in Japanese Patent Publication No. 5B-23047.

This horseshoe has a horseshoe main body made of aluminum alloy with dovetail-like grooves formed on the underside, which are filled with an elastic cushioning material such as soft synthetic resin.

In addition to forming a buffer part, a through hole is provided at the bottom of the groove, and the buffer material is also filled in the through hole to improve the adhesion to the horseshoe body, and to provide a stable horseshoe with a buffer part. It was successful and is now in practical use.

[Problems to be Solved by the Invention] In this horseshoe, the shock absorbing part absorbs the impact upon landing, and at the same time, the buffer part recedes from the bottom surface of the main body to form a concave part where dirt and sand can enter, thereby preventing slips. The cushioning part has elasticity and absorbs the shock when landing. However, since it expands and contracts inside the groove, and there is some movement, even the holding structure with dovetail grooves and through holes cannot completely suppress this movement, and further improvements are needed in terms of durability. Ta.

In addition, when the cushioning part retreats when landing, a depression is formed on the underside of the horseshoe body, which is expected to bite the ground, but when the ground is hard, especially in cold regions in winter, the In the case of freezing and easy-to-freeze conditions, the formation of this depression alone cannot prevent slipping.

In consideration of horseshoes used under such harsh conditions, the present invention further improves the horseshoes according to the above-mentioned proposals, forms a stronger buffer section, and provides horseshoes with excellent durability. In addition, it is an object of the present invention to provide a horseshoe that effectively prevents slipping upon first landing and further enhances the protection of the hoof.

[Means for Solving the Problems] The present invention was developed based on the above-mentioned purpose, and is characterized by a dovetail that extends the width of the bottom over the entire length of the horseshoe body at the center of the bottom surface. A groove-shaped groove is formed, and a strong cushioning material having elasticity, such as rubber or soft synthetic resin, is filled in the groove to form an abutment, and a groove is formed along the length of the groove. The present invention relates to a horseshoe in which a coiled metal spring material is inserted and embedded integrally in the slow-impact portion, and a method for manufacturing the same.

In the present invention, the spring material has a substantial outer diameter larger than the narrowest groove width part of the dovetail groove in a normal state, and when inserted into the groove, the spring material is stretched to have its outer diameter. is inserted into the groove in this state and laid down, and then relaxed so that part of the circumference engages with both side wall surfaces of the groove as the outer diameter expands. In this state, a part of the spring material protrudes over the entire length from the opening of the groove, and then protrudes at a distance from the surface of the buffer part formed by the buffer material to be filled, so that the buffer part is connected to the groove. It is characterized by its ability to be fixed internally and to function as a slip prevention 11: spike.

Hereinafter, embodiments illustrating the horseshoe of the present invention will be described in detail.

[Example] FIG. 1 is a plan view of a horseshoe according to the present invention.

FIG. 2 is a bottom view, and FIG. 3 is an enlarged vertical sectional view taken along the line m--■ in FIG. 1.

In the drawing, l is the horseshoe body, 2 is the lower surface 3 of this horseshoe body
4 is a dovetail-shaped groove formed along the entire length along the central part of the road surface. 5, numeral 5 designates a spring material which is also inserted into the groove and buried in the buffer section.

The horseshoe main body 1 is formed by extrusion molding an aluminum alloy into a bar shape, which is then cut to a predetermined length and curved into a horseshoe shape.
12 will be integrally formed.

Reference numeral 6 denotes an iron lip raised at the tip of the upper surface 7 of the horseshoe main body l. In this embodiment, a rib-shaped wall is raised along one end of the upper surface 7 during extrusion molding, and this It is formed by removing a portion of the mold after forming it.

The groove 2 is formed into a substantially dovetail groove shape by widening the depth, that is, the bottom, and narrowing the area near the opening. A through hole 8 is provided, and nail holes 9 for hoof dressing are formed at appropriate intervals avoiding the through hole 8.

The through hole 8 is for penetrating and fixing a buffer material to prevent the movement of the buffer part 4, and the opening facing the upper surface 7 is enlarged in diameter to form a retaining part 10.

The spring material 5 is first inserted into the groove 2 formed along the entire length together with the horseshoe body 1, and then the buffer material is filled in a molten state, and the buffer material 4 is formed by hardening. The spring material will be embedded in this buffer section.

The spring material 5 used here is a steel wire formed into a coil shape, and its substantial outer diameter in the relaxed state is larger than 14@ of the narrowest part of the groove 2. When inserting the spring material, first, as shown in FIG. After that, the enlargement is loosened and the outer diameter is returned to the original diameter.

By expanding the outer diameter of the spring material that has been unstretched after being inserted in this way, the grooves 2 are formed on both sides of the periphery over the entire length.
The elastic force is applied to both inner walls of which the diameter has been reduced, causing them to engage with each other, and the object stays inside the binding due to its own restoring force (see Fig. 5).

In addition, this spring material may have a space between the pitches of the spiral in its original form, but when it is in its original form, the space is closed, and when it is inserted into the groove, the pitch of the spiral is opened and it constantly contracts. A strong retention state can be obtained by applying force to engage the side wall portion.

In this embodiment, as shown in No. 3 UgJ, this spring material has a substantially triangular shape from the end face direction and fits in the bottom of the groove 2 which has an enlarged diameter, thereby further stabilizing the attachment to the side wall part, and at the same time The grooves protrude from the opening and extend from the lower surface 3 at intervals along the length of the groove.

The buffer portion 4 is formed by filling a resilient yet strong buffer material such as rubber or soft synthetic resin 1, such as urethane resin.

This buffer portion is formed by inserting the spring material 5 into the groove by the above-described method.
It is formed by filling the entire length of the groove with the buffer material in a heated and melted state after inserting the buffer material, and at this time, it is also poured into the through hole 8 to integrally form the retaining part IO. At the same time, the spring material 5 inserted earlier is embedded and hardened to be integrated and fixed inside the groove.

FIG. 6 shows another embodiment in which a part of the embodiment described above is modified.

In this embodiment, the spring material 5 to be inserted into the groove 2 has a circular shape when viewed from the end face direction, and the groove 2 is also formed deeper than the previous embodiment to stabilize the fit of the spring material. This is what is shown.

In addition, No. 7.8 shows still another embodiment, in particular, in this embodiment, the protruding portion 5a exposed from the lower surface 3 of the spring material 5 embedded and fixed in the buffer portion 4 is cut in the middle,
This figure shows the case where it is made into a needle shape.

The present invention is constructed as described in the above embodiment, and the horseshoe main body 1 has a buffer portion 4 formed in the groove 2 formed on the lower surface 3 thereof, and a spring inserted into the groove due to the formation of the buffer portion. The material 5 is fixed and a part of it is attached to the lower surface 3.
A protruding portion 5a having a spike base is formed to protrude further.

[Effects of the Invention] As explained above, according to the present invention, the cushioning portion 4 having elasticity is formed in the rigidity of the horseshoe main body l made of metal, in the above embodiment, aluminum alloy, so that when landing In addition to being able to alleviate the impact of landing, the cushioning part retreats into the groove when landing, forming a concave part that allows the ground to dig into the ground, thereby effectively preventing slips. At the same time, in the horseshoe according to the present invention, the spring material 5 embedded in the buffer section engages with both side walls of the groove 2 and fixes the buffer section 4 inside the groove, so a firm fixation is expected. There is an effect that can be done.

Moreover, as mentioned above, the buffer section 4 is made of an elastic material and expands and contracts each time it lands on the ground, and is forced to move somewhat within the groove, so when driving a nail, etc., it does not move at all. If a fixing method that does not allow this occurs, the cushioning material itself will be damaged and broken, but the spring material 5 in the present invention expands and contracts together with the cushioning portion 4 due to its elasticity.

Since the horseshoe still maintains engagement with the strings while moving and its movement is not restrained, it is possible to provide a strong and extremely durable horseshoe without stressing and damaging the buffer section.

On the other hand, in the horseshoe of the present invention, a part of the spring material 5 embedded in the buffer portion 4 protrudes from the lower surface of the horseshoe main body to form a spike-shaped projection i5a, so that slipping of the horseshoe can be effectively avoided. In addition to protecting the hooves, it has the effect of reducing the burden on the legs. In particular, the hardness of the protrusion 5a can be increased by using a hard metal spring material with high wear resistance.
It is even more effective when used on frozen land, and is effective in protecting hooves and legs from stress caused by slips.

As described above, the horseshoe of the present invention is a horseshoe that has a highly durable buffer section, and at the same time, the horseshoe that has this buffer section is inserted by stretching the spring material into the groove formed on the lower surface of the horseshoe body. However, it can be manufactured by subsequently filling and curing the buffer material, which has the advantage of excellent productivity.
