Rabbit box apparatus for laboratory rabbits, comprising a box having:
- a bottom wall;
- a pair of opposed side walls;
- and a front wall having a rabbit neck-receiving opening, said front wall being connected to said bottom and side walls to define a rabbit enclosure;
- a top wall hinged to one of said side walls to open or close said enclosure in rabbit receiving and restraining relation respectively;
- and box back plate means for engaging the hind leg feet of a rabbit restrained in said box, said back plate means including a bar extending transversely of said enclosure opposite said front wall, said box back plate means further comprising a three-sided frame longitudinally interfitting said box bottom and side walls, and including also fasteners securing said frame to said box walls in back plate bar positioning and enclosure extension-delimiting relation.
Rabbit restraining apparatus for laboratory animals, said apparatus comprising a box and an adjustably interfitting frame defining a longitudinally variable rabbit enclosure;
- said box being formed of sheet metal shaped to define a bottom and an integral pair of opposed upstanding side walls having raked leading edges;
- said box further having:
- a front wall secured to said bottom wall and to said side walls along said raked edged thereof;
- a top wall;
- said top wall and said front wall being cooperatively relieved to define a rabbit neck-receiving opening;
- rounded means lining said opening and including a metal bead enclosing the opening edges on both sides thereof;
- said top wall being hinged along one longitudinal side margin to one of said side walls, said top wall having a downwardly directed flange at the other of its longitudinal side margins to interfit the opposite box side wall;
- latch means including a male latch element having a movable button and detent ball actuable by said button, said male latch element being carried on said top wall inwardly adjacent said top wall flange, and a female latch element supported by said opposite side wall registrable with said male latch element and adapted to receive said male latch element in detented locked or detented unlocked relation responsive to detent ball actuation by said movable button;
- said frame being formed of sheet metal into bottom and side walls;
- said frame side walls and said box side walls carrying cooperating pin and slot means for guided longitudinal adjustment of said frame and box;
- fasteners securing the relative adjustment of said frame and box, said frame side walls having vertical slots beyond said box, and a transverse bar mounted on said frame sidewalls at said vertical slots;
- fastening means securing said bar to said frame side walls in vertically adjusted relation, said bar being pivotable in its vertically adjusted relation to delimit the longitudinal extent of said rabbit enclosure independent of the frame adjustment relative to the box.
