Description

[Detailed explanation of the idea] The present invention relates to horseshoes used for racehorses and the like.

In general, when replacing a racehorse's horseshoes with new ones, it is said to be appropriate to do so at the same time as the horse's hoof (nails) have grown and the old parts are shaved off, which is called hoof trimming. ing.

The period of hoof trimming is approximately 25 to 30 days for a standard horse, and therefore the horseshoes are worn out so that they will need to be replaced after 25 to 30 days. is considered ideal.

Furthermore, if a horseshoe made entirely of a material that hardly wears, such as steel, is attached, it often adversely affects the horse's limbs and muscles.

By the way, current horseshoes for racehorses are made only from light alloys such as aluminum alloys, so they are subject to rapid wear, and the front part of the ground contact surface decreases diagonally after about 15 days for horses walking normally. I end up.

Therefore, horseshoes must be replaced with new horseshoes before the hoofs (claws) have outgrown the hoof trimming period.

For this reason, the distance between the nail holes in the old horseshoe and the nail holes in the new horseshoe is too close, making the hoof more likely to crack and causing damage to the hoof.

In this way, horseshoes made only of light alloy are light and reduce so that they can be easily walked against the horse's hooves, so they are very good for the hoof and limbs. It becomes a drawback.

For this reason, in some countries overseas, a single steel strip is embedded in the front part of the light alloy horseshoe, which is subject to severe wear, to reduce the rapid wear and tear.

However, even if only one steel strip is embedded in a light alloy like this, the light alloy part will be reduced first and the steel strip will stick out, making the hoof less stable and causing fractures or sprains. It has the disadvantage of being the cause.

The purpose of the present invention is to provide a horseshoe that has moderate wear and does not affect the horse's limbs.

The present invention prevents excessive wear and stabilizes the entire hoof by arranging at least two wear-resistant members on the ground surface of the horseshoe body made of light alloy or the like and shaped into a substantially arcuate, so-called horseshoe shape. In this way, the aim is to achieve the above objective.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

FIG. 1 shows a bottom view of the horseshoe according to the present invention as seen from the ground surface side, and FIG. 2 shows a sectional view of the central part thereof.

In these figures, two trapezoidal protrusions IA and 1B are in contact with the ground side of the horseshoe body 1, which is made of an aluminum alloy such as duralumin, or other light alloy, and has a substantially semicircular arc shape and a so-called horseshoe shape. It is formed integrally over almost the entire circumference on the ground side, and a groove 1C is formed between these protrusions IA and IB.

A plurality of nail holes 1D are provided in the middle of this groove 1C, that is, in the left and right portions in FIG.

Furthermore, the protrusions 1A on the inner circumferential side are shaped slightly lower than the protrusions 1B on the outer circumferential side.

A first wear-resistant member 2 made of steel or the like is disposed on the protrusion IA on the inner peripheral side of the horseshoe main body 1 over substantially the entire length of the protrusion 1A, that is, almost the entire circumference of the horseshoe main body 1.

This first wear-resistant member 2 is approximately 3 m from the inner circumference of the horseshoe body 1.
It is installed at a position about m inside, and has a thickness of 1.5 mm.
A member with a height of 4 mm is extended over the entire length of the horseshoe body 1.
It is inserted into the forging with about 1 mm protruding from the ground plane of A.

Further, as shown in an enlarged view in FIG. 3, the first wear-resistant member 2 may have a serrated uneven portion 2A on the end surface of the horseshoe body 1 on the side protruding from the protrusion 1A. .

A second wear-resistant member 3 made of steel or the like is disposed at a predetermined length on the front side of the protrusion 1B, that is, at the center of the protrusion 1B on the side opposite to the horseshoe-shaped opening. It is set up.

This second wear-resistant member 3 is approximately 3 m from the outer circumference of the horseshoe body 1.
A member that is installed at a position approximately 100 m inward and is forged into the horseshoe body 1 with a member 3 mm thick, 6 mm high, and 50 mm long protruding approximately 1 mm from the ground surface of the protrusion 1B. It is.

According to this embodiment configured in this way, the second
The wear-resistant member 3 can reduce wear on the front part of the horseshoe and improve the hoof's turn, while the first wear-resistant member 2 on the inner circumferential side can maintain stability of the entire hoof.

In addition, by providing the two inner and outer wear-resistant members 2 and 3, as the horseshoe body 1 made of light alloy decreases, the grass (
It can properly bite into turf, sand, soil, etc., preventing skidding and making fractures, sprains, etc. less likely to occur.

Furthermore, the uneven portion 2A provided on the ground contact side of the first wear-resistant member 2 can also better prevent skidding.

In addition, since the entire horseshoe wears out approximately on average due to the first and second wear-resistant members 2 and 3, the period of hoof trimming, that is, 25
They wear out to the point that they need to be replaced after about 30 days, and have little effect on the horse's hooves.

Furthermore, since the horseshoe main body 1 is shaped by forging, it can be strengthened.

In addition, in actual practice, the first and second wear-resistant members 2 and 3 are not limited to being integrally formed as shown in the drawings, but may be divided into several pieces.

Further, the first and second wear-resistant members 2 and 3 are not necessarily limited to one thread each, and may be provided with two or more threads each. In short, the wear-resistant members 2 and 3 are not necessarily provided in two or more threads at different positions in the radial direction for the entire horseshoe. Bye.

According to the present invention as described above, it is possible to provide a horseshoe that is less abrasive and less harmful to a horse's limbs.
