BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slide type opening / closing plate device provided at a front opening of a breeding rack in an animal breeding room for breeding experimental animals in a favorable environment suitable for research.

[0002]

2. Description of the Related Art FIG. 4 shows an animal breeding room of a conventional one-way flow system, 1 is a working room where breeding workers work,
A retinal chamber 3 partitioned by a lower wall 2 and the like is provided adjacent to the working chamber 1. A breeding rack 4 is provided in the working chamber 1 so that the back portion is connected to the letter chamber 3 in a manner that allows easy removal. This breeding rack 4
A rising plate 5 made of, for example, stainless steel is provided in the back opening of each of the shelves so as to open the upper part in a slit shape, and an antistatic type is provided in the front opening of each of the shelves of the breeding rack 4. A hanging curtain 6 made of a vinyl chloride sheet or the like is provided so that the upper part is closed. A breeding container or a wire netting cage is installed on each shelf of the breeding rack 4. An air inlet 7 is provided at the top of the working chamber 1. In the figure, the arrow indicates the air flow distribution, the arrow 8 indicates air supply, and the arrow 9 indicates exhaust.

That is, an operator enters the working room 1 and raises an animal in a raising container or a wire net cage installed on the raising rack 4. In this case, the letter chamber 3 needs only to have a space capable of being exhausted, and does not require a space for an operator to enter, so that the space of the working chamber 1 can be increased correspondingly, and an efficient work can be realized.

Also, the animal breeding room is forcibly ventilated.
That is, an exhaust device such as a fan is connected to the retin chamber 3, and the exhaust of the retin chamber 3 is forcibly performed. As a result, fresh air from the air inlet 7 is raised on each shelf of the breeding rack 4. It flows through the container or the wire mesh cage to the retin chamber 3 and is exhausted to the outside. In this case, the rising plate 5 provided in the breeding rack 4 can control the amount of intake air, and the hanging curtain 6 can prevent the atmosphere in the breeding rack 4 from flowing out to the working chamber 1 and the air flow can be properly adjusted. Can be converted. The height of the rising board 5 is 11/1 of the height of each shelf of the breeding rack 4.
The height of the hanging curtain 6 is preferably 1/3 of the height of each shelf of the breeding rack 4. For example, if the height of the breeding rack 4 is 30 cm, the height of the rising board 5 is 27.5.
cm, and the height of the banner 6 may be 10 cm.

Further, by promptly exhausting the polluted air that has passed through the breeding container or the wire net cage installed in the breeding rack, the polluted air may be mixed with the clean air flowing into the room. It is possible to create a comfortable working environment that is free from allergies and odors.

Further, by supplying clean air into the breeding container or the wire net cage, it is possible to create a favorable breeding environment in which microbial contamination between experimental animals is much less than in the past and there is less retention of ammonia. You can

[0007]

In the animal breeding room of such a unidirectional flow system, the height of the curtain hung on the front of the breeding rack must be limited in order to take workability into consideration. Therefore, the front opening of the rearing rack becomes large, the inflow wind velocity into the rearing rack becomes low, and the air in the rearing rack may flow back due to the turbulence of the airflow on the work area side. There was a fear that it would go to the person.

The present invention has been made in view of the above circumstances, and it is possible to prevent the backflow of contaminated air by reducing the opening area on the front of the breeding rack, and to increase the opening area on the front of the breeding rack by a simple operation. An object of the present invention is to provide a slide-type opening / closing plate device for a breeding rack that can be made larger to improve workability.

[0009]

In order to solve the above problems, the present invention provides an opening / closing plate provided at the front opening of a breeding rack so as to be vertically slidable so that the opening / closing plate can be moved downward. Slide to reduce the opening area on the front of the breeding rack to prevent backflow of contaminated air, and slide the opening / closing plate upward to increase the opening area on the front of the breeding rack to improve workability. is there.

Embodiments of the present invention will be described in detail below with reference to the drawings.

1 to 3 show an embodiment of the present invention, FIG. 1 is a schematic perspective view, FIG. 2 (a) is a side view and FIG. 2 (b).
2A is an enlarged view of part A of FIG. 2A, FIG. 3A is a front view of the structure, and FIG. 3B is an enlarged view of part B of FIG. 3A. That is, in the animal breeding room of the one-way flow system, the rail slits 12 for sliding are provided substantially vertically in both front portions of each shelf of the breeding rack 11. The upper end of the top rail slit 12 and each rail slit 12
The lower end portion of each is provided with an inclined portion 121 that is inclined. A rotating shaft 13 is movably inserted into each of the rail slits 12, and an opening / closing plate 14 is attached to the rotating shaft 13 so as to close most of the front opening of the breeding rack 11. As shown in FIG. 2B, the opening / closing plate 1
Reference numeral 4 is attached to the rotating shaft 13 by a bearing 15, and the opening / closing plate 14 is attached to the rail slit 12 by the rotating shaft 13 so as to be rotatable in the arrow direction. Further, as shown in FIG. 3 (b), the rotary shaft 13 is attached to the rail slit 12 via the spring member 16 of the holding mechanism, and the rotary shaft 1
The knobs 17 are attached to both end portions of the rail slit 12 which penetrate the rail slit 12.

That is, the uppermost shelf of the breeding rack 11 is the rotating shaft 1.
Opening / closing plate 14 when 3 is at the upper end of rail slit 12
Is attached so as to close most of the front opening of the breeding rack 11, and the other shelves of the breeding rack 11 have the opening / closing plate 1 when the rotating shaft 13 is at the lower end of the rail slit 12.
4 is mounted to close most of the front opening of the rearing rack. In this state, the front opening of the breeding rack 11 has only a small slit-shaped opening 18 below the opening / closing plate 14. Therefore, breeding rack 1
The air flowing into No. 1 is fast, and the contaminated air in the breeding rack 11 does not flow backward and flow toward the operator. On the other hand, when the worker performs the breeding work using the breeding containers or the wire net cages installed on the shelves of the breeding rack 4, the knob 17 is grasped and the rotary shaft 13 is fixed to the rail slit 12.
By moving along the opening / closing plate 14, the opening / closing plate 14 is held at a predetermined position by the spring member 16 of the holding mechanism, and the front opening of the breeding rack 11 is largely opened. In this way, the workability of the operator is improved by greatly opening the front opening of the breeding rack 11.

[0013]

As described above, according to the present invention, the open / close plate provided at the front opening of the breeding rack is slid downward to reduce the opening area of the front of the breeding rack, thereby making It is possible to prevent contaminated air from flowing back to the operator side, and by sliding the open / close plate upward to increase the opening area on the front of the breeding rack, the workability of the operator can be improved. it can.
