Field of the Invention The present invention relates to a cage for breeding medium-sized animals which are bred as pets for medical or pharmaceutical experiments or the like, and more particularly to cleaning the inside, opening and closing a front door, supplying food, and the like. The present invention relates to a cage for breeding medium-sized animals capable of facilitating the operation of the above, cleaning the inside of the cage and reducing noise, and improving the breeding environment of medium-sized animals such as dogs, cats and rabbits.

[0002]

BACKGROUND OF THE INVENTION Generally, medium-sized animals such as dogs, cats, rabbits and the like for medical or pharmaceutical experiments or as pets are housed individually in box cages individually.

[0003]

2. Description of the Related Art Conventionally, as these box-type cages, as shown in FIG.
Since medium-sized animals such as dogs generally prefer dark places, the left side plate, right side plate (53), rear plate (54), and ceiling plate (55) are each formed on a plate material, and manure is caged. There is a configuration in which a lattice-like floor nest (57) is arranged on the lower surface so that the floor nest (57) can be easily discharged below the main body (56).

A latch lock (58) is attached to the front door (51) so that a pin (59) fixed to the cage body (56) can be engaged with a pin tip of the latch lock (58). It is composed. Also,
A feeding window (60) is formed in the front door (51), and a feeder (61) is installed when feeding, and a metal belt (62) is provided from the front and rear.
It is configured to be fixed with.

On the other hand, a water supply nozzle (64) is provided on the rear plate (54).
Is installed so as to protrude into the cage body (56), and the accommodated medium-sized animal is configured to drink water by touching the water supply nozzle (64).

As shown in FIGS. 6 and 7, the floor nest (57)
Is a stainless steel pipe (65) having a circular cross-section, formed in a lattice shape by arranging it side by side with its length direction facing forward and backward, to a support frame (66) provided at the lower part of the cage body (56). It is configured so that it can be attached to the lower part of the cage body (56) by being inserted from the front. The support frame (66) is configured to support two floor nests (57, 57) vertically, and one of the floor nests (57) is detached after the other floor nest (57) is attached. Washed. At this time, since each of the stainless steel pipes (65) is configured to be rotatable, feces and the like adhered between the stainless steel pipes (65) can be easily washed.

[0007]

The above prior art has the following problems. (1) Left side panel, right side panel (53), rear panel (54) and ceiling panel (5
Since each of 5) is formed of a plate material, contaminated air easily stays in the cage, which adversely affects the housed medium-sized animals and the workers who breed and observe them.

(2) As shown in FIG. 7, the left and right side plates (5
At the lower end of 3), a support frame (66) for supporting the floor nest (57) from the left and right and guiding the insertion and removal of the floor nest (57) and a frame of the cage body (56) are arranged. There is also a problem that manure easily accumulates above 66), etc., and that the inside of the cage is contaminated and that the contained animals eat feces.

(3) The left side plate, the right side plate (53) and the rear plate (5
4) and the ceiling plate (55) are fixed to each other by welding or the like, and it is not easy to wash every corner in the cage, and it is difficult to maintain a good breeding environment for the housed animals.

(4) Since there is a relatively large space under the floor nest (57) for accommodating a waste tray or the like,
The lower nest of the nests (57) can be pulled out relatively easily.
, The upper nest cannot be easily pulled out, and it is not easy to replace the nest at the time of cleaning or the like.

(5) The locking operation by the latch lock (58) is performed by gripping the handle (68) protruding from the pin (67), moving the pin toward the distal end, and engaging the pin distal end with the receiving metal (59). It is necessary to stop and rotate the handle (68) to engage the guide (63) of the latch lock (58), which makes the operation complicated. Moreover, the latch lock
Since there is a play between (58) and the receiver (59) and the front door (51), when the contained animal places the forelimb on the front door (51), the cage body (56) and the front door (51) Noise occurs between the two.

(6) Feeding window (6)
Since the metal belt (62) for fixing the feeder (61) to the feeder (61) is easily pressed or released by the housed animal, the feeder (61) is fixed by the metal belt (62) to feed securely. Must be securely tightened, which makes the feeding operation complicated.

(7) When the feeder (61) is not attached, the housed animal may come out of the feeding window (60) with a head or the like, and the metal belt (62) may be damaged or the housed animal may be injured. There is a fear that.

(8) The housed animal normally takes a posture facing the front door (51) from which the outside can be checked, and the stainless steel pipes (65) constituting the lattice of the floor nest (57) are in the longitudinal direction. The stainless steel pipe (65) is easily pinched between the fingers of the housed animal, and the housed animal may suffer from interdigital inflammation.

(9) Further, since the stainless steel pipe (65) constituting the lattice has a circular cross section and is rotatable, the house animal riding on the floor nest (57) has a foot between the pipes. The stainless steel pipes (65) need to be arranged with a small interval so as not to be injured by sneaking in and to give a sense of stability to the contained animals. As a result, there is a problem that the feces of the housed animal do not fall smoothly from the gap of the lattice, and the inside of the cage body (56) is contaminated.

The present invention solves the above-mentioned conventional problems, and facilitates operations such as cleaning the inside, opening and closing the front door, and supplying food.
It is an object of the present invention to provide a cage for breeding medium-sized animals, which can clean the inside of the cage and reduce noise and improve the breeding environment of medium-sized animals.

In addition, since the lock is made by using the spring elasticity of the gripping part, the front door can be prevented from rattling during locking, noise can be reduced, and when the front door is completely closed, it is always locked and locked Otherwise, since the upper and lower insertion pins do not engage with the receiver, the front door is in a half-open state, so that the presence or absence of locking can be easily confirmed from the state of the front door.

(E) According to the third aspect of the present invention, the feeding of the housed animal can be achieved by simply placing the bowl-shaped feeder containing the feed into the feeding window from above the push-out preventing piece and placing the feeder on the mounting table. Can be prevented from jumping out and falling outside, so that the fixing operation with the metal belt as in the prior art is not required, and it can be performed extremely easily with one hand. In addition, since the projection prevention frame is fixed above the feeder, the accommodated medium-sized animal cannot come out of the feeding window through its head, etc. Can be prevented.

(F) In this case, the above-mentioned table is attached to the lower edge of the feeding window at an angle to the inside of the cage body so as to be inclined downward. Since the feeder returns to the inside and is always received at the predetermined position by the receiving member, it is possible to more reliably prevent the feeder from jumping out and falling outside.

(G) In the present invention 4, the floor nest has the respective wires constituting the lattice arranged side by side in the longitudinal direction, and the upper surface of each wire is formed in a substantially horizontal plane. In addition, the wire is hardly caught between the fingers of the housed animal, and it is possible to prevent suffering from interdigital inflammation. In addition, since the upper surface of each wire is formed in a substantially horizontal plane, the excrement can be easily dropped downward by expanding the lattice spacing, keeping the cage body clean and giving a feeling of stability to the housed animals. Can be.

(H) In the fifth aspect of the present invention, the same effects as those of the first to fourth aspects of the present invention are provided.
(A) to (g) can be performed together, and medium-sized animals can be bred in a better breeding environment.
