The present invention relates to an attachment for a horseshoe,
which horseshoe possesses two legs, and the attachment possesses basic components,
which by means of a connecting part are connected with each other at an adjustable
distance, and the attachment is provided with a peg or is designed for fitting a
Such attachments for improving the grip of the hooves of
a riding animal, in particular a horse, are known. Such grip-improving attachments
are necessary in particular when riding on a slippery surface, such as grass that
may be or not may be wet, concrete and ice. US 1,454,999 describes an attachment
that as connecting part possesses a central hub, whose ends are threaded. The threads
at the two ends of the central hub have opposite pitches. Both ends of the central
hub are provided with basic components, which basis components can be placed at
an adjustable distance from one another with the aid of the central hub. In order
to prevent the attachment becoming detached, each basic component comprises two
basic component segments, with each leg of the horseshoe being clamped between the
two basic component segments of a basic component by means of screwing. Each basic
component also comprises a peg, which peg improves the grip for the riding animal.
A problem of the known attachment is that it is relatively
heavy. Moreover, fastening is difficult and time consuming, because two pairs of
screws are needed to fasten the two basic components to the horseshoe. The screw
heads are necessarily located at the side facing away from the hoof, that is to
say, in practice they are directed towards the surface on which the riding animal
walks. This means that these screws may become damaged, with all its consequences.
It is the object of the present invention to provide an
attachment of the above-mentioned kind that can be fastened and detached easily,
while there is the guarantee that the attachment cannot become loose whereby the
animal would no longer have an improved grip. Loosening could result in mal no longer
enjoying an improved footing. Loosening could cause injury to the animal and/or
To this end the device according to the invention is characterised,
in that the attachment is designed to be braced against the inner rim of the horseshoe
against its two leg portions, the attachment comprises at least two basic components,
each basic component comprising a flat plate portion and the plate portions, fastened
to the horseshoe, each face towards the underside of a respective leg portion of
the horseshoe, and the basic component comprises a raised edge, which raised edge
is provided with at least one tapering element, which tapering elements can be moved
up against the inner side of the horseshoe by increasing the distance between the
basic components, with the tapering elements being embodied such that they are able
to penetrate into the horseshoe and in this manner brace the attachment against
both leg portions.
It has been shown that an attachment braced in this manner
against both leg portions, can be fastened very securely to the horseshoe. This
reduces the risk of a riding or pack animal, such as a horse, loosing its footing.
The attachment according to the invention is very light. Although it is thinkable
that the connecting part is, or can be provided with a calk, it is preferred that
at least one flat plate portion on its side facing away from the horseshoe is, or
can be provided with a calk.
A suitable embodiment is characterised, in that the connecting
part for varying the distance between the basic components is a connecting part
that is rotatable in relation to the basic components, wherein a first basic component
is provided with either a male or a complementary female element, and the rotatable
connecting part at the respective end is provided with the other element, in that
the male and female elements are provided with thread, and in that the connecting
part is rotatably connected with a second basic component.
In the case of, for example,
- the rotatable connecting piece having a polygonal shape so that it can be engaged
with a pair of pliers or open-end spanner or
- having a hole into which a rod-like tool can be inserted, the distance between
the first and the second basic component can thus be varied in a simple manner.
An attractive embodiment is characterized, in that the
second basic component is provided either with a second male element or a second
complementary female element, which second male and female elements are provided
with threads whose pitch is counter to that of the male and the female element,
and that the other second element is provided at the end of the rotatable connecting
part, where it is connected with the second basic component.
In this way, the distance between the two basic components
can be adapted more quickly with one single rotation.
According to a preferred embodiment, the connecting piece
is reduced near its midpoint.
The reduction helps to avoid that the frog of the horse's
hoof can touch the connecting piece.
According to an important embodiment, the points are tapered
and so sharp and hard that they are able to penetrate the material of the horseshoe.
This avoids the necessity for complementary openings in
the horseshoe for the accommodation of the points, and affords a greater degree
of freedom when placing the attachment.
The present invention will now be elucidated by way of
the drawing, in which
- Fig. 1 shows a bottom view of an attachment according to the invention;
- Fig. 2 shows a top view of the attachment illustrated in Fig. 1; and
- Fig. 3 shows a front view of a variant of the attachment illustrated in Fig.
The attachment 1 illustrated in Fig. 1 comprises two basic
components 2, 2', each of which is formed from a plate. During use of the attachment,
a respective end of a leg portion of a horseshoe A (indicated with broken lines)
rests on each plate. The basic components 2, 2' are connected via means 3, which
make it possible to vary the distance between the basic components 2, 2'. In the
embodiment illustrated in Fig. 1, the means 3 are formed by the two threaded male
elements 4, 4' (forming in this embodiment part of the basic components 2, 2') and
an elongate hexagonal body 5 equipped with the male elements 4, 4', which male elements
4, 4' can be screwed into complementary female elements (indicated with a dot-dash
line) at the two ends 11, 11' of the elongate body 5. The pitches of the two male
elements 4, 4' run counter to one another. By turning the elongate body 5, it is
thus possible to vary the distance between the basic components 2, 2'.
In the illustrated embodiment, the attachment 1 is provided
with two calks 6, 6', which in effect ensure that the horse's footing on the surface
is improved. The calks 6, 6' may be detachable calks, in which case the basic components
2, 2' may, for example, be provided with thread (not shown) to allow the calks 6,
6' to be screwed into the basic components 2, 2'. Alternatively, the calks 6, 6'
may in accordance with the illustrated embodiment also form an integral part of
the attachment 1, in particular of the basic components 2, 2'.
The plates of the basic components 2, 2' are provided with
a raised edge 7, 7' (Fig. 1). Each of these is provided with hard-steel points 8,
8'. These are sufficiently sharp and hard to be able to penetrate into the iron
of the horseshoe. This ensures that the basic components 2, 2' engage the respective
leg portions of the horseshoe A without the attachments 1 being able to move out
of place. If the horseshoe A is provided with complementary openings for the points
8, 8', the hardness of the points is of minor important. However, this solution
is considered to be less attractive.
To fit the attachment 1, the basic components 2, 2' are
braced against the respective leg portions of the horseshoe. By turning the hexagonal
body 5 in relation to the basic components 2, 2', the distance between the two basic
components 2, 2' is caused to increase and the points 8, 8' penetrate the inner
rim of the respective leg portions of the horseshoe. Thanks to the use of thread,
a very considerable force can be exerted with little effort. The penetration of
the points 8, 8' into the iron of the horseshoe A, makes it substantially impossible
for the attachment to move non-coaxially in relation to the connecting piece. This
ensures that notwithstanding the very considerable forces exerted on the hooves
while riding the horse, the attachment will not come loose.
Since the components 2, 2', 5 are able to turn in relation
to each other, it is preferred that means 10 be provided for producing a slight
amount of friction, so that the influence of gravity will no longer cause the components
2, 2', 5 to turn in relation to one another. This facilitates fitting the attachment
to the horseshoe A. In the embodiment shown, the means 10 are springs 10, 10'. These
also provide some protection for the threads of the male elements 4, 4'.
To remove the attachment, the hexagonal body 5 is rotated
in the opposite direction, which brings the basic components 2, 2' closer together
When a body 5 having a hexagonal cross section is used,
it can simply be tightened or loosened with an open-end spanner. The body 5 is preferably
provided with a reduced portion 9, which makes it lighter as well as affording room
for the frog of the hoof when the horse is standing on the respective hoof.
In Fig. 2 a top view of the above-described attachment
1 is shown. In the embodiment shown, raised edges 7, 7' are provided that preferably
have a narrow and thin edge portion, which at the side of the hoof projects over
the horseshoe A.
Instead of a polygonal, e.g. hexagonal body 5, it is also
possible to use a body that is not polygonal such as a cylindrical body 5, in which
case the cylindrical body 5 is perpendicular to its longitudinal direction provided
with a hole (not shown). By means of a pin that can be inserted into the hole, the
distance between the basic components 2, 2' can be varied in the same manner as
with a hexagonal body 5. This is not preferred, because the hole will quickly become
clogged with dirt.
The means 3 are preferably placed such that when fitted
to the horseshoe of a horse, they are positioned under the concave part in the hoof
such that they do not come into contact with the horse and unnecessary discomfort
The present invention is elucidated by way of a preferred
embodiment of the attachment according to the invention. It goes without saying
that other embodiments are possible, without departing from the scope of the appended
claims. For example, the basic components 2, 2' may engage holes in the horseshoe.
Also, the attachment may engage additional positions on the horseshoe, such as the
front inner side of the horseshoe. If the inner rim of the horseshoe is provided
with notches or cavities, they may also be used to enable the attachment to engage
The term connecting part refers to a portion of the attachment
that can at least be functionally connected with the basic components. That is to
say, it is conceivable that one or both basic components together with the connecting
part form a unit composed of separate elements. According to the invention it suffices
if the basic components and the connecting piece rotatably engage one another. Thus
it suffices that either of the elements chosen from basic component and connecting
piece functions as stop for the other element. In principle, it is possible to vary
the length of the connecting piece. To this end, the connecting piece has to consist
of (at least) two components that can be rotatably connected with one another via
thread. Since in such a case the two components have to be rotated in relation to
each other, two tools will be needed to implement this, which makes fitting more
awkward and therefore does not merit preference.
