DESCRIPTION:
BRIEF SUMMARY
This invention relates to a horseshoe. The object of the invention has been to provide a heavy load shoe which offers as to its design and function the support, protection and cooperation which all the mechanisms of the hoof should be offered; outdoors, indoors, summer and winter.
To this end the horseshoe according to the invention includes a plurality of sub-portions in accordance with the disclosure in the opening section of the accompanying claim 1, and according to the invention these portions are arranged as disclosed in the characterizing clause of said claim. In subclaims advantageous detail designs within the scope of claim 1 are disclosed.
Horseshoes, which besides the usual "horseshoe form portions" have portions located as defined in the opening section of claim 1, are known from U.S. Ser. Nos. 786,763 and 808,436. Said first mentioned specification relates to a horseshoe having longitudinal and transverse portions intended to hold and carry a releasable calk device, and the last mentioned specification relates to a shoe having tract portions pivotally secured to side portions of the shoe, said tract portions being resiliently held by longitudinal and transverse portions. Per se, these known designs have thus nothing in common with the invention.
Extensive tests, and shoe wear images showing the cooperation hoof/shoe obtained at such tests, have shown that when employing the shoe according to invention in extremely hard foot work the hoof will be loaded in a way which is very much more favourable to the hoof than if correspondingly loaded while using horseshoe designs for the same purpose, hitherto known.
The general design of the horseshoe according to the invention will become apparent from the following description thereof when considered together with the accompanying drawings in which FIG. 1 shows a plan view of a shoe, FIG. 2 shows the same shoe in a cross section along line C--C in FIG. 1, and FIG. 3 is a photo of the surface, facing the hoof, of a shoe according to the invention after having been used, to a certain extent, under heavy load.
In a principal embodiment in accordance with the invention the shoe has essentially plane-parallel top and bottom sides (FIG. 2). It can thus be cut or punched from a plate having a thickness adjusted to the size of the shoe in its plane of treading and to the properties of material, the thickness usually being of the order of between 3 and 7 mm, but of course the shoe can also be cast to shape.
As shown in FIGS. 1 and 3 the shoe is of the kind which has a curved part which covers from below, in use of the shoe, the supporting rim of the hoof along the toe part thereof and the side and tract portions located on either side of that toe part. In FIG. 1 the corresponding portions of the shoe are indicated by dashed lines. As already seen from the reference above to claim 1 there is between the two tract portions 1c a cross portion 2 extending essentially at right angles to the longitudinal direction C--C of the shoe, in addition to which a longitudinal portion 3 located essentially centrally extends in a longitudinal direction of the shoe, between the toe portion 1a and the cross portion 2.
Between the side portions 1b and the transverse and longitudinal portions 2 and 3, respectively, there are thus openings 4 on either side of the longitudinal portion, through which openings the radius groove is accessible for cleaning and clay packing.
The hoof radius will receive indirect ground contact through the medium of the substantially T-shaped shoe portion, according to the invention integral with the remaining portions of the shoe, which T-portion the transverse and longitudinal portions 2 and 3, respectively, form together. Said contact takes place in a manner thoroughly improving the supporting capacity of the shoe in comparison with shoes which cover essentially only the supporting rim of the hoof. Hereby formation of bolus and a narrow tract hoof is prevented.
In order to offer in a shoe according to the invention the best possible support surface on th
