Description

[Detailed Description of the Invention] The present invention relates to a breeding cage for breeding experimental animals, especially cats.

Generally, the bottom of laboratory animal cages is made of slats so that the animal's excrement can fall down through the slats, but if a cat stays on the slats all day, it can hurt their feet and cause stress. It accumulates and causes mental abnormalities. Therefore, as shown in Fig. 1, there is a cage a in which a step is made of a flat plate b at the back of the cage a so that the cat can normally climb onto the step and rest. On the other hand, when observing cats in captivity or administering injections,
I want to hold the cat near door c at the front of the cage so it doesn't move, so I hold the cat near door c as shown in Figure 2.
A frame plate e is provided inside the cage a so as to be able to move back and forth, and the frame plate e is usually kept close to the rear wall d, but in case of an emergency, the frame plate e protrudes forward from the cage a. There is a device in which a cat can be clamped and fixed between the door c and the frame plate e by pulling out the operating rod f and bringing the frame plate e closer to the door c. However, if it is attempted to install both the stepped portion shown in FIG. 1 and the frame plate shown in FIG. 2 in one cage, there is a problem that they interfere with each other and are useless.

In order to solve the above-mentioned problems, the present invention divides the frame plate shown in FIG. The lower half of the frame plate is horizontal when it is located in the back, and when the frame plate approaches the door, the lower half can be rotated to a vertical position. It is intended to provide a cage.

Embodiments of the present invention will be described below with reference to the drawings.
3 to 5 schematically show the cage of the present invention. The cage 1 has a front opening with a grid-like second
It can be opened and closed with , and the bottom is covered with 3 drainboards. Each operating rod 5 is fixed to the left and right sides of the upper frame plate 4.
protrudes forward of the cage 1, and is fitted and supported in a tube 6 protruding forward from the front opening edge of the cage 1 so as to be movable back and forth. The lower frame plate 7 has its base end pivotally connected to the upper frame plate 4 by a hinge 8 so as to be able to swing vertically.
The tip is extended and the extended portion is formed into a four semicircular curved surface portion 9 centered on the hinge axis. cage 1
A crosspiece 11 is provided protruding from the inner surface of the left and right side walls 10 at the deep part of the cage 1, and the lower frame plate 7 is connected to the crosspiece 11 at the deep part of the cage 1.
When the upper frame plate 4 is brought closer to the door 2, the lower frame plate 7 comes off the crosspiece 11 and rotates downward under its own weight, causing the rear surface of the upper frame plate 4 to be maintained horizontally. When it hits a stopper 12 protruding downward, it becomes vertical and cannot be rotated beyond the vertical position. Usually the third
Since the upper frame plate 4 is located at the inner part of the cage 1 as shown in the figure, the lower frame plate 7 is placed on the crosspiece 11 and maintained horizontally. Therefore, the cat is slatted 3
and the lower frame plate 7. When observing a cat or administering an injection, when the upper frame plate 4 is moved forward as shown in Fig. 4, the lower frame plate 7 comes off the crosspiece 11 and rotates downward under its own weight. . As the upper frame plate 4 is brought closer to the door 2, the lower frame plate 7 further rotates due to the cat's body, but eventually it hits the stopper 12 as shown in Figure 5 and becomes stuck in the vertical position.
The cat is pressed against door 2 and cannot move.

FIGS. 6 and 7 are a detailed sectional view and a rear perspective view of the main parts of another embodiment of the cage of the present invention. In this figure, the four sides of the upper frame plate 4 are bent rearward at right angles, and the lower side piece 13 has a notch at the part where the hinge 8 is attached, and the remaining part allows the rotation of the lower frame plate 7 to be perpendicular. It also serves as a stopper to stop it in certain situations. The left and right sides and the proximal end of the lower frame plate 7 are bent at right angles to the back surface to form left and right side pieces 14 and a base end piece 15, which protrude from the inner surfaces of the left and right side walls 10 at the deep part of the cage 1. The left and right side pieces 14 and a part of the proximal end piece 15 near the left and right side pieces 14 stand on the provided crosspiece 11, and the lower frame plate 7
becomes horizontal, and when the lower frame plate 7 is removed from the crosspiece 11, it rotates downward due to its own weight, and when pushed from the front, the base end piece 15 (part of which is cut out for attachment of the hinge 8) ) comes into contact with the side piece 13 of the upper frame plate 4 and is in a vertical state. Note that a reinforcing rod 16 is bridged between the tip of the four semicircular curved surface portion 9 centered on the axis of the hinge 8 and the base end of the lower frame plate 7. Further, the operating rod 5 can be fixed with a push bolt hinged to the tube 6. Further, a wooden board or the like may be pasted on the surface of the lower frame plate 7.

The present invention is as explained above, and the lower frame plate is pivoted to the upper frame plate so as to be able to swing vertically, and the lower frame plate normally serves as a comfortable seating surface for the cat at the back of the cage. , near the door, it can fulfill the original role of holding the cat against the door, and is easy to use, making it extremely useful for managing the breeding of laboratory cats.

Claims (1)

[Scope of utility model registration request] The frame plate that can move forward and backward in a cage with a door on the front and holds the animal in the cage against the door is divided into two halves, vertically, and the lower frame plate is pivoted to the upper frame plate so that it can swing vertically. The tip of the lower frame plate is extended to form a four semicircular curved surface centered on the axis of the pivot, and the lower frame plate is attached to the inner surface of the left and right side walls of the cage at the back of the cage. A protruding crosspiece is provided to support the plate horizontally, and a stopper is provided on the upper frame plate to prevent the lower frame plate from rotating downwardly beyond the vertical position when it is removed from the crosspiece.
