Fig. 9 is an end elevational view of another portion of the horseshoe of Fig. 1,
Fig. 10 is a side elevational view of another portion of the portion of the
horseshoe of Fig. 9, and
Fig. 11 is a top plan view of a detail of the horseshoe of Fig. 1.
Referring to the drawings, there is illustrated a horseshoe according to the invention,
indicated generally by the reference numeral 1, for securing to the hoof of a horse
(not shown), although it will be readily apparent to those skilled in the art that the
horseshoe according to the invention may be adapted for securing to any other
animal with a similar type hoof to that of a horse. The horseshoe 1 comprises an
arcuate shoe element 3 of forged metal. A pair of studs 4 also according to the
invention are secured to respective free ends 5 of the shoe element 3.
Each stud 4 is of metal and comprises a ground engaging element 6 which tapers to
a distal point 7 for gaining grip in soft ground for the horse. A shank 9 extends
axially from the ground engaging element 6 of each stud 4 for engaging a
corresponding receiving bore 10 extending through the shoe element 3. The
receiving bore 10 extends from a ground engaging face 11 of the shoe element 3 to
a hoof engaging face 12 of the shoe element 3. and is counter-bored at 13 from the
hoof engaging face 12 as will be described below.
A pair of bayonet members 14 extend sidewardly from the shank 9 on respective
opposite sides thereof for engaging corresponding bayonet receivers provided by
bayonet receiving grooves 15 formed into a circumferentially extending bearing
surface 16 formed by the counter-bore 13. Bayonet member accommodating slots
18 extend axially along the receiving bore 10 and radially into the shoe element 3
from the ground engaging face 11 to the bearing surface 16 for accommodating the
bearing members 14 as the shank 9 is being urged into the receiving bore 10. The
bearing surface 16 extends between each bayonet receiving groove 15 and the two
bayonet member accommodating slots 18 and is inclined from the bearing member
accommodating slots 18 to the bayonet receiving grooves 15, so that as the shank 9
is being rotated through a predetermined angle of 90° for urging the bayonet
members 14 from the bayonet accommodating slots 18 along the bearing surface 16
to aiign with the corresponding bayonet receiving grooves 15, the shank 9 is drawn
into the receiving bore 10 from the ground engaging face 11.
A spring loaded washer 20 is located between an abutment surface 20 of the ground
engaging element 6 of each stud and the ground engaging face 11 of the shoe
element 3, and accommodates the shank 9 of the corresponding stud 4 into the
receiving bore 10, so that as the shank 9 is being rotated in the receiving bore 10
through the predetermined angle of 90° for aligning the bayonet members 14 with
the corresponding bayonet receiving grooves 15, the washer 20 is compressed,
thereby urging the bayonet members 14 into engagement with the corresponding
bayonet receiving grooves 15 with a snap-fit action for releasably retaining the
bayonet members 14 in the bayonet receiving grooves 15, and in turn the
corresponding stud 4 in the shoe element 3. The incline on the bearing surface 16
can most ciearly be seen in Figs. 7, 8 and 11 and inclines upwardly from the bayonet
member accommodating slots 18 to the bayonet receiving grooves 15 in the
direction of the arrows A of Fig. 11. The spring loaded washer 20 in this
embodiment of the invention is a disc ‘washer of dome shape of the type which will
be weii known to those skilled in the art.
As can be seen in Figs. 5 and 6, the length of the shank 9 is less than the depth d of
the shoe element 3, so that clearance is provided between the end of the shank 9 of
each stud 4 and the hoof engaging face 12. This permits ready and easy securing
and removal of the studs 4 in and from the shoe element 3.
In use, to secure a pair of studs 4 to the shoe element 3, the shank 9 of each stud 4
is inserted through the corresponding washer 20 and into the receiving bore 10
through the ground engaging face 11 with the bayonet members 14 aligned with and
slideable through the bayonet member accommodating slots 18. When the bayonet
members 14 arejust clear of the bayonet member accommodating slots 18, the
shank 9 is rotated in the bore 10 by a spanner engaging a hexagonal portion 22 of
the ground engaging element 6 of the stud 4, and rotated through 90°. As the shank
9 is being rotated through 90° in the receiving bore 10, the bayonet members 14
bear on the bearing surface 16, which in turn causes the shank 9 to be drawn further
into the receiving bore 10, thus compressing the washer 20 between the ground
engaging element 6 and the ground engaging face 11 of the shoe element 3. As the
bayonet members 14 are poised on the edge of the bayonet receiving grooves 14,
the compressive force acting on the washer 20 is at its maximum, and when the
shank 9 is rotated through the full 90°, the bayonet receiving members 14 engage
the corresponding bayonet receiving grooves 15 with a snap-fit action. Thus, the
studs 4 are securely engaged and retained in the shoe element 3 of the horseshoe
1. To remove each stud 4 from the shoe element 3, a spanner is again engaged on
the hexagonal portion 22 of the ground engaging element 6, and the shank 9 is
again rotated through 90°, thus disengaging the bayonet members 14 from the
corresponding bayonet receiving grooves 15, and aligning the bayonet members 14
with the bayonet member accommodating slots 18. Once the bayonet members 14
are aligned with the bayonet member accommodating slots 18, the shank 9 can be
withdrawn from the receiving bore 10, thus disengaging the stud 4 from the shoe
element 3.
While the receiving bore 10 and the counter-bore 13 which defines the bearing
surface 16 and the bayonet receiving grooves 15 as well as the bayonet member
accommodating slots 18 have been described as being formed in the shoe element,
in certain cases, it is envisaged that inserts may be provided for engaging
corresponding bores in the shoe element, and the receiving bore 10, the counter-
bore 13, the bayonet receiving grooves 15 and the bayonet member accommodating
slots 18 would be formed in the insert. Suitable securing means would be provided
for securing the insert in the shoe element.
