DESCRIPTION:
BRIEF SUMMARY
This invention relates to livestock leg restrainers.
It is an object of the invention to provide a live stock leg restrainer which may be used with live stock to hold two or more legs of an animal in order to restrain the animal during husbundary procedures, transportation or inspection.
In one form the invention resides in a livestock leg restrainer comprising a first member formed with a set of at least two open ended recesses located in side by side relationship and a second member pivotally mounted to one end of the first member and movable to a first position closing each recess, a retaining means adapted to engage the first and second members when the second member is in the closed position.
According to a preferred feature of the invention the pivotal interconnection between the first and second members permits selective slidable movements between the members to vary the area of the spaces defined in the recesses when the second member is in the closed position.
According to a further preferred feature of the invention said recesses are substantially U-shaped in configuration.
According to a further preferred feature of the invention the open faces of adjacent recesses are directed in opposed relation to each other.
According to a further preferred feature of the invention the second member is formed with recesses of a complementary configuration to the recesses of the first member.
The invention will be more fully understood in the light of the following description of one specific embodiment. The description is made with reference to the accompanying drawings of which:
FIG. 1 is a plan view of the livestock leg restraining means of the embodiment in the closed position;
FIG. 2 is an isometric view of the leg restraining means of the embodiment in the open position; and
FIG. 3 is a sectional view along the line 3--3 of FIG. 1.
The embodiment is directed towards a leg restraining means for use with livestock and in particular sheep. The leg restraining means provides a means of engaging all four legs of an animal simply and effectively.
The embodiment comprises a first and second member 11 and 12 which are pivotally interconnected by a hinge 13 at one end. The other end of the first member supports a locking means 14 which is capable of engaging with the second member 12 when it is engaged in the closed position with the first member 11. The first member 11 has a convoluted configuration whereby it defines four U-shaped recesses 15 each having an open face whereby the open face of adjacent recesses is directed in opposed opposite directions. The second member 12 also has a convoluted configuration, between the hinge 13 and the other end which is engageable with the locking member 14, to define recesses 16 which are substantially complementary with the recesses 15 of the first member. It is the complementary nature of the recesses 15 and 16 of the first and second member 11 and 12 respectively by which a space is defined which conforms substantially to the configuration of the leg of an animal.
To accommodate for a variation in leg dimensions the second member 12 is slidably adjustable on the first member 11 through the hinge 13 to vary the dimensions of the space defined by the recesses 15 and 16. The hinge 13 comprises a slot formed on the one end of the second member 12 which receives the one end portion of the first member 11. The end 18 of the end portion of the first member 11 is enlarged to prevent disengagement of the end portion from the slot 13 while a lug 19 is fixed to the end portion on the side of the slot 17 remote from the end 18 to prevent movement of the slot along the first member 11.
The slot 17 is formed with three spaced notches 21 the dimensions of which corresponds substantially with the external dimensions of the one end portion which is substantially circular. One side 20 of the end portion is flattened such that the transverse dimensions between the one side and the opposite side corresponds substantially to the minimum dimensions of the slot between the notches 21.
