Description
本発明は、競走馬用の蹄鉄に関するものである。
The present invention relates to a horseshoe for a racehorse.
従来、競走馬の蹄には蹄鉄が取着されており、同蹄鉄により蹄の保護及び競争能力の向上が図られている。調教時には調教用の蹄鉄が使用されるとともに、競争時には競争用蹄鉄に打ち替えられる。また、打ち替えの負担を軽減するために、調教時及び競争時に兼用可能とした兼用蹄鉄も使用されている。調教用蹄鉄は、極軟鋼で形成され、競争用蹄鉄及び兼用蹄鉄はアルミニウム合金で形成される。
In the past, horseshoes have been attached to the horseshoes of race horses, and the horseshoes have been used to improve whale protection and competitiveness. In addition to training, horseshoes for training are used, and at competitions, they are replaced with competition horseshoes. Also, in order to reduce the burden of replacement, dual purpose horseshoe that can be used at the time of training and competition is also used. The training pig iron is formed of extremely mild steel, and the competition pig iron and dual purpose pig iron are formed of an aluminum alloy.
このような蹄鉄は、蹄に対して釘あるいは接着剤を用いて装蹄され、蹄の蹄機作用を阻害しないように、蹄踵部に当接する蹄鉄の鉄尾部は蹄に固定されない。
また、走行時には、蹄踵部から着地するため、蹄踵部にかかる荷重が増大する。この荷重は、走行速度が上昇するにつれて大きくなる。そこで、競走馬の蹄肢を保護するために、蹄鉄の鉄尾部には、クッション機能を備えることが好ましい。 Such a horseshoe is mounted on the heel using a nail or an adhesive, and the iron tail of the horseshoe that abuts on the heel is not fixed to the heel so as not to inhibit the mechanical action of the heel.
In addition, when traveling, the load applied to the buttocks is increased because landing from the buttocks. This load increases as the traveling speed increases. Therefore, in order to protect the limbs of the racehorse, it is preferable to provide the iron tail portion of the horseshoe with a cushioning function.

In addition, when traveling, the load applied to the buttocks is increased because landing from the buttocks. This load increases as the traveling speed increases. Therefore, in order to protect the limbs of the racehorse, it is preferable to provide the iron tail portion of the horseshoe with a cushioning function.
こうしたクッション機能を備える蹄鉄としては、主に蹄肢の弱い馬を対象としたものであり、蹄が接触する面である接蹄面にゴムなどの緩衝材が貼り付けられたものがある。しかしながら、こうした蹄鉄の場合、蹄が接触することによって緩衝材が摩耗しやすい。そのため、装蹄用の釘が緩みやすく、蹄からの蹄鉄の落下、すなわち落鉄が発生するおそれがある。
The horseshoe having such a cushioning function is mainly intended for horses with weak limbs, and there is a horseshoe in which a shock absorbing material such as rubber is stuck on a contact surface which is a surface with which a heel is in contact. However, in the case of such a pig iron, the shock absorbing material is apt to be worn by the contact of the crucible. Therefore, the nail for fitting is easily loosened, and there is a possibility that the dropping of the pig iron from the beard, that is, drop iron may occur.
一方、特許文献１には、競走馬の蹄肢を保護するために、鉄尾部から鉄側部にかけての外周部に周方向に沿って延在する溝状の凹部を形成し、同凹部にゴムなどの緩衝材を埋設した蹄鉄が開示されている。
On the other hand, in Patent Document 1, in order to protect the limbs of the racehorse, a groove-shaped recess extending along the circumferential direction is formed on the outer periphery from the iron tail to the iron side, and rubber is formed in the recess A pig iron having a buffer material embedded therein is disclosed.
ところで、特許文献１に開示された蹄鉄では、凹部が、鉄尾部から鉄側部にかけての外周部に周方向に沿って延在しているため、鉄尾部及び鉄側部の強度を確保することが難しく、割れが生じるおそれがある。更に、溝状の凹部に緩衝材を充填する構成であるため、凹部の最深部まで緩衝材を充填することが難しい。そのため、クッション機能を安定して確保する上で改善の余地を残すものとなっている。
By the way, in the case of the horseshoe disclosed in Patent Document 1, the strength of the iron tail portion and the iron side portion is secured because the concave portion extends along the circumferential direction to the outer peripheral portion from the iron tail portion to the iron side portion. Is difficult and may cause cracking. Furthermore, since the groove-shaped recess is filled with the buffer material, it is difficult to fill the buffer material to the deepest part of the recess. Therefore, there is room for improvement in securing the cushion function stably.
この発明はこのような事情に鑑みてなされたものであり、その目的は、落鉄の発生を抑制することができるとともに、鉄尾部のクッション機能を安定して確保することのできる蹄鉄を提供することにある。

According to such a configuration, the shock absorbing property of the iron tail portion is improved because the shock absorbing material is filled over the entire width direction of the iron tail portion. Further, since the through hole penetrates the iron tail in the width direction, the shock absorbing material is easily filled in the entire inside of the through hole.

Therefore, on the inner circumferential surface of the first through hole 10, a helically extending projection is formed. Each first through hole 10 is filled with a buffer material 11 made of EVA resin (ethylene-vinyl acetate copolymer resin).
図３及び図４（ｂ）に示すように、各鉄側部３には、各釘溝８の底部と蹄鉄１の外周面との間を貫通する複数（本実施形態では５つ）の第２の貫通孔１２が上記延在方向に互いに等間隔をおいて設けられている。各第２の貫通孔１２は雌ねじ孔である。したがって、第２の貫通孔１２の内周面には、螺旋状に延びる突起が形成されている。各第２の貫通孔１２には、第１の貫通孔１０と同様に、ＥＶＡ樹脂からなる緩衝材１１が充填されている。ただし、第２の貫通孔１２の直径は、第１の貫通孔１０の直径よりも小さく設定されている。
As shown in FIG. 3 and FIG. 4 (b), each of the iron side portions 3 includes a plurality of (five in the present embodiment) of penetrations between the bottoms of the nail grooves 8 and the outer peripheral surface of the horseshoe 1. Two through holes 12 are provided at equal intervals in the extending direction. Each second through hole 12 is a female screw hole. Therefore, on the inner circumferential surface of the second through hole 12, a helically extending projection is formed. Each second through hole 12 is, like the first through hole 10, filled with a shock absorbing material 11 made of EVA resin. However, the diameter of the second through hole 12 is set smaller than the diameter of the first through hole 10.
第１の貫通孔１０及び第２の貫通孔１２に充填される緩衝材１１は、第１の貫通孔１０及び第２の貫通孔１２の一端側から他端側（例えば蹄鉄１の外周側から内周側）に向かって充填される。
The cushioning material 11 filled in the first through hole 10 and the second through hole 12 is from one end side to the other end side of the first through hole 10 and the second through hole 12 (for example, from the outer peripheral side of the pig iron 1) It is filled toward the inner circumference).
次に、蹄鉄１の作用について説明する。
蹄鉄１の上面を蹄の接地面にあてがい、複数本の釘を各釘溝８内の釘孔９から蹄に打ち込むことにより、蹄鉄１が蹄に固定される。また、鉄頭部２及び鉄側部３を接着剤で蹄に固定することも可能である。 Next, the action of thepig iron 1 will be described.
By applying the upper surface of thehorseshoe iron 1 to the ground contact surface of the eyebrow and driving a plurality of nails from the nail holes 9 in each nail groove 8 into the eyebrow, the horseshoe iron 1 is fixed to the eyebrow. It is also possible to fix the iron head 2 and the iron side 3 to the crucible with an adhesive.

馬の走行時には、蹄が蹄踵部から蹄尖部に向かって順次着地する。このとき、鉄尾部４の第１の貫通孔１０に充填された緩衝材１１により蹄踵部に作用する衝撃が緩和される。また、第２の貫通孔１２に充填された緩衝材１１により、蹄側部に作用する衝撃が緩和される。
When the horse is running, the heels land sequentially from the buttocks to the cusp. At this time, the shock acting on the buttocks is mitigated by the shock absorbing material 11 filled in the first through holes 10 of the iron tails 4. Further, the shock absorbing material 11 filled in the second through holes 12 reduces the impact acting on the heel side.
鉄尾部４は蹄に固定されないので、蹄の蹄機作用を阻害することはない。

Also, according to the above configuration, unlike a conventional horseshoe where a cushioning material such as rubber is attached to a contact surface, not only horses with weak limbs but also healthy horses with no limb problems. Can also be used for the purpose of prevention of failure. In addition, since the cushioning material does not undergo large elastic deformation as in the above-described conventional horseshoe, the ground can be strongly kicked up, which contributes to the improvement of the traveling speed.
