2. Description of the Related Art Cages for breeding animals for research are required to be clean, and washing and sterilization are usually required when replacing animals. Also, for cleaning and sterilization work and animal replacement work,
It is always necessary to keep spare animal cages.
In a commonly used box-forming animal breeding cage, labor is required for cleaning and sterilization, and the storage space must be wide. Therefore, there is a demand for facilitating washing and sterilization work and reducing the storage space by making the animal breeding cage an assembly type. Then, conventionally, the following two animal breeding devices (a) and (b) have been proposed in response to the above-mentioned demand. (A) As shown in FIG. 13, cylinders that are alternately superposed in a concentric state along the vertical direction on each of adjacent side edges of each side plate 50 made of metal that defines the periphery of the animal breeding cage S. A connecting cylinder 51 having a shape of
The connecting pins 52 are connected to each other by inserting the connecting pins 52 from above over the connecting cylinders 51 provided on the adjacent side edge portions thereof, and are L-shaped provided on the upper portions of the inner surfaces of the respective side plates 50. A metal rectangular reinforcing frame 54, which blocks the upward movement of each connecting pin 52 inserted into the connecting cylinder 51, is detachably fitted and held over the fitting piece 53 of FIG. Further, the side plates 50 facing each other in the left-right direction
Each of the upper ends of the above is bent outward to form a suspension piece 55 that is placed and supported in a suspended state so that it can be inserted into and removed from the rearing frame (not shown) in the front-rear direction. In addition, each of the lower end portions 50a of the side plates 50 is bent toward the animal breeding cage S side, and the bottom plate 56 made of a metal net is placed and supported over the bent lower end portions 50a (for example, Jikken Sho 63. -25
981).

(B) As shown in FIG. 14, a breeding frame 60 capable of compartmentalizing a plurality of animal breeding cages S in the left-right direction.
The four first rail members 60A extending in the left-right direction, the four second rail members 60B extending in the front-rear direction, and the four second rail members 60B extending in the vertical direction.
A front side plate 61 that forms a framework from a column support member 60C, and that forms a partition around the animal breeding cage S across both the first rail members 60A on the upper side and the first rail members 60A on the lower side, respectively. Of the side plate 62 and the left and right lateral side plates 63, a guide member 64 having a guide groove 64a for inserting and guiding the lateral side plate 63 from the front-rear direction is fixed, and at the bottom of the guide member 64 located on the lower side. A support plate 65 for mounting and supporting the lateral side plate 63 inserted at a predetermined position in the guide groove 64a is fixed to each of them. In addition, on the guide member 64 located on the upper side, a receiving plate 67 that mounts and supports a top plate 66 so that the top plate 66 can be inserted and removed in the front-rear direction.
And a pair of left and right projecting pieces 62a projecting from the lower end edge of the rear side plate 62 are inserted into and supported by the first crosspiece member 60A located at the lower rear portion.
And a rear side plate 6 is formed on the rear end edge of the top plate 66.
A pair of left and right support pieces 66a for receiving and supporting the upper end portion of 2 are formed to project downward. Further, a fitting support plate 70 for fitting and placing a bottom plate 68 made of a metal net and a hooker 69 for dropping and guiding animal excrement in an overlapping state is fixed to the guide member 64 located on the lower side, The front side plate 61 is rotatably and pivotally connected to the front end edge of one of the lateral side plates 63 in a detachable state (for example, Jikho Sho 63-4).
3898).

[0004]

In the conventional animal breeding apparatus, since each of the plurality of side plates and the bottom plate partitioning and forming the periphery of the animal breeding cage S can be disassembled, for example, a plurality of side plates are integrally formed. Compared with existing and foldable structures, even when exchanging animals and excrement of the animals that were raised last time and residual slag of food, etc. are washed and sterilized, each side plate and Although it is possible to completely clean and sterilize each of the bottom plates, there is still room for improvement in the following points.

That is, in the case of the former former animal breeding apparatus, in addition to the plurality of side plates 50, the adjacent side plates 50 are used.
Since a plurality of connecting pins 52 for connecting each other and a rectangular connecting frame 54 that blocks the upward movement of each connecting pin 52 are impeded, the number of component parts is large and A lot of labor is required for assembly / disassembly work and cleaning / sterilization work. Moreover, the plurality of side plates 50 are preliminarily assembled in a box shape by the connecting pins 52 and the connecting frames 54 with the bottom plate 56 placed and supported over the lower end portions 50a thereof, and then the box bodies are used as a breeding frame. Since it is suspended, when it is necessary to remove only the bottom plate 56, which is easily soiled in a short period of time as compared with the side plate 50, for cleaning and sterilization, the step of extracting the box from the breeding frame, the connecting frame 54 of each side plate 50 A step of removing from the fitting piece 53 and a step of pulling out the connecting pin 52 connecting the adjacent side plates 50 are necessary, and a lot of labor is required for the attachment / detachment work of the bottom plate 56. Further, since each of the plurality of side plates 50 is made of a metal material, each side plate 50 becomes heavy and requires a great deal of labor to handle the side plates 50, resulting in a decrease in efficiency of assembly / disassembly work and cleaning / sterilization work. easy.

Also, in the case of the latter conventional animal breeding apparatus, the rear side plate 62 and the left and right lateral side plates 6 are provided on the breeding frame 60 side.
3. Since the support portion for supporting each of the bottom plate 68 is provided, the number of components is smaller than that of the former, and the assembling and disassembling work can be performed easily. Each of them is assembled on the breeding frame 60 side in a mounted state, and a part of the guide member 64 for inserting and guiding the lateral side plate 63 is located in the animal breeding cage S so that it is located at a corner of the animal breeding cage S. The excreted excrement easily travels through the guide member 64 and the breeding frame 60 and leaks to other animal breeding cages S and the outside, and moreover, the contact point between the lower end of the lateral side plate 63 and the support plate 65 and the rear side plate 62. Lower end and first of breeding frame 60
Since urine stones are likely to be generated at each of the contact points with the cross member 60A, there is a problem in the breeding environment, and moreover, many are used for cleaning and sterilizing the breeding frame 60 and the side plates 61, 62, 63 after disassembly. Takes time. In particular, the left and right sides of the support plate 65, which contacts the lower end of the lateral side plate 63, have guide grooves 64a for insertion and removal.
Since it is surrounded by the guide member 64 that forms the part, it is easy to clean the site.

The present invention has been made in view of the above circumstances, and its purpose is to simplify the structure of the breeding frame by rational remodeling using the breeding frame, and at the same time, replace the animal. It is possible to efficiently and easily perform the assembly and disassembly work and the cleaning and sterilization work that are required in connection with this, or the work of removing and attaching the bottom plate that tends to get soiled quickly, and moreover, when raising animals, the excreted urine does not leak to other places. In other words, it is possible to raise the animal in a hygienic environment in which the occurrence of urinary stones is suppressed.
