Abstract
Abstract The object of the invention is a horseshoe, which includes a flat sandwich construction component that essentially corres-ponds to the form of a horse's hoof and well as devices (3, 9) for attaching the sandwich construction component to the hoof, when the sandwich construction component includes a flexible layer (5) which absorbs impacts and which is attached to an essentially stiff support layer (4). In order for the horseshoe to reduce the stresses on the horse's legs as wells, as being simultaneously light and easily and firmly attached to the horse's hoof, it is characteristic that the flexible layer (5) is located between the aforementioned stiff support layer (4) and a second essentially stiff layer (1) in such a way that the stiff layers (1, 4) are completely separated by the flexible layer (5) while making possible the movement of the stiff layers in every direction in relation to each other by means of the flexible layer. The stiff layer (1) of the sandwich con-struction component that lies away from the hoof includes holes (2) for horseshoe nails (3).
Description
2l~7 ~ ~ti HORSESHOE
The obj ect of the invention is a horseshoe, which includes a flat, sandwich construction componsnt that corresponds essen-tially to the form of the horse's hoof as well as devices forattaching the sandwich component to the hoof, in which case the sandwich component includes a flexible layer that absorbs impact, which is attached to an essentially stiff support layer that comes immediately against the horse's hoof and which is located between this and a second essentially stiff layer in such a way that the stiff layers are inseparable from the flexible layer.
Diseases in, and injuries to locomotory organs are the most usual reason for the interruptiGn and termination of the com-petition careers of horses involved in equestrian sport. A hard practice or competition surface will increase the impact ir-ritation to legs. Leg problems have been found to be general even in horses that are not involved in sport or competition, such problems being often due to the horse's legs being subject to too great an impact loading. Attempts have been made to reduce the stress problems by placing various kinds of absorbers between the shoe and the hoof: one well known example makes a traditional horseshoe made from iron flexible by using various kinds of absorbers between the shoe and the hoof, which have all, however, had unfavorable effects on the hoof. For example US patent publication 4 5~5 068 presents such a horseshoe, which consists of a rubber piece in a frame, which is directed towards the surface, i.e. road. The rubber piece operates effectively as an absorbing member, but being a soft material it is also liable to rapid wear.
The intention of the invention being presented is to form an improved horseshoe, which does not have the defects of the known horseshoes. In order to achieve this goal it is essentially characteristic of the horseshoe in accordance with the invention that the stiff layer of the sandwich construction away from the hoof includes holes for horseshoe nails, the diameter of the holes exceeding the diameter of the head of the nail by at least 1 mm.

accordance with the invention is presented in the accompanying Patent Claims 2 - 7.
The basic idea behind the invention presented here is based on the idea that by sufficiently altering its construction a horseshoe can be made in such a way that it removes the defects of a traditional horseshoe.
The most important advantages of a horseshoe in accordance with the invention are that it reduces the stress on the legs of the horse while it is also light, sufficiently durable, and can be easily and securely attached to the horse's hoof without re-quiring special nails or other devices. Further, due to its simple construction, its manufactùre is relatively cheap.
In what follows the invention is illustrated with the aid of one of its advantageous forms of application described in greater detail by reference to the accompanying drawings, in which in Figure 1 the horse shoe is shown from above, and 0 in Figure 2 the horseshoe is in longitudinal section along line II - II of Figure 1.
In Figure 1 a sandwich construction horseshoe in accordance with the invention is seen from above, in which case it shows the layer 1 that is on the opposite side from the hoof and which comes in contact with the surface, as well as the holes 2 formed in it together with the shoe nails 3. Layer 1 is made from wear-resistant, stiff plastic, such as large-molecule polyethene, or other wear-resistant and light, but relatively stiff material.
Metals, such as e.g. steel or aluminium, can also be considered.
In order to improve the wear-resistance of the base layer 1 the areas in it most subject to wear are encased with a very thin layer of hard metal, which is illustrated by the shaded areas in Figure 1 and which is in principle created in the same way as the surface of sandpaper.
Figure 2 shows the sandwich construction of the horseshoe in greater detail. The sandwich construction consists of three 3 2~ P)~
layers arranged so that between the stiff layer 1 and the essentially stiff support layer 4 that comes against the hoof of the horse there is a flexible rubber layer 5, which completely separates the stiff layers 1 and 4 from one another. Layer 4, which lies against the hoof, can be made from glass-fibre plastic or from the same material as layer 1. The thicknesses of layers 4, 5, and 1 are about 2, 4, and 3 mm in the same order.
In order for the middle layer to have good impact absorption it must be sufficiently thick. The sandwich construction shown makes it possible for the stiff layers 1 and 4 to move relative to each other by means of the flexible layer 5, this being very important in order that in practice the horseshoe reduces the stresses on the legs of the horse. Figure 2 also shows that there is a certain amount of empty space around the heads 6 of the shoe nails 3, which permits the aforementioned movement. In practice this is realized by making the diameter of the hole 2 in layer 1 for nail 3 about 1 - 3 mm greater than the diameter of the head of the shoe nail 6. A depression 7 is made in the flexible middle layer and extends nearly to layer 1 that lies against the hoof. The depression 7 thus does not extend to layer 1, instead a distance of 1 mm remains between the base of the depression and layer 4, because it is intended that the flexible layer 5 gives support to the shank ~3 of the shoe nail 3 at the point which is close to layer 4 lying against the hoof. It is important to support nail 3 at this point, which is highly stressed in use, in which case the nails can easily begin to loosen. In order that nail withstands both the shear and tensile stresses on it, an ordinary washer 9, which provides good support in the base of the depression 7, is set around it. It is probable that an excellent joint can be achieved by means of the washer 9, which deforms permanently to corrrespond to the nail shank 3 when the shoe nail is hammered home. By reducing the depth of the depression 7 from that shown in Figure 2 a joint is created in which the head 6 of the shoe nail 3 protrudes slight-ly from the level surface of the layer 1. A protruding nail 3 ofthis kind may be considered to act in the manner of a non-slip device.

It can also be seen from Figure 2 that the internal edges 10, 11 of layers 1 and 4 are bent against the elastic layer 5. The bent edges improve the attachment of layers 1 and 4 to middle layer 5 when shear stresses arise in normal circumstances in the shoe in the direction of layers 1 and 4. It should be noted that the opposing edges do not touch one another, as this would make effective flexibility between layers 1 and 4 impossible.
The invention is described above with the aid of only one of its advantageous forms of application. By means of this it is desired not to limit the invention, which in its details can be adapted in many ways within the framework of the accompanying Patent Claims. This being the case, layers 1 and 4 need not be plastic but may be made of e.g. carbon fibre or some other suitable material. It is important, however, that the surface of layer 1 is highly resistant to wear. The mutual thicknesses of the layers can be altered in accordance with the material being used. It is also possible to imagine that there would be more than the aforementioned three layers in the sandwich construc~
tion.
