Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a cage for raising sterile experimental animals, pets, etc. The present invention relates to an animal breeding cage installed in the middle of an airflow path from the air outlet to the exhaust port.

[Conventional technology]

In the above-mentioned animal breeding cages, in order to efficiently supply clean air blown from the air outlet to the installed cage and reduce the required amount of clean air to be blown, air is supplied between the installed cage and the ceiling of the room. Although partitions are often installed, conventionally,
In providing the partition, a partition plate is placed between the ceiling and the cage, and is connected and fixed to each of the ceiling and the cage using bolts or the like.

[Problem that the invention attempts to solve]

However, in order to connect and fix the partition plate to the ceiling and the cage, it is necessary to remove the partition plate when moving the cage, for example, to disinfect the cage outdoors or rearrange the cage, or to reinstall the cage afterwards. Attaching partition plates after installation is a troublesome and time-consuming task, and in many cases requires specialized workers.

An object of the present invention is to provide an animal breeding cage that allows easy movement of the cage even though it is provided with partitions.

[Means for solving problems]

The characteristic structure of the animal breeding cage according to the present invention is as follows:
It has a plurality of ventilation holes as a partition extending between the cage body and the ceiling of the chamber, and can be switched between a partition state extending from the cage body to the ceiling of the chamber and a storage state stored in the cage body side. The main feature is that a freely operable partition is attached to the cage body, and its functions and effects are as follows.

[Effect]

In other words, by simply installing the cage in a predetermined position in the room and switching the partition body to the partition state, it is possible to obtain the same partitioning function as the conventional partition plate that is connected and fixed to the ceiling and cage respectively. Furthermore, when moving the cage, the cage can be moved simply by switching the partition plate from the partitioning state to the retracted state.

By the way, if the cage is simply moved, a simple plate may be used as the partition that can be freely switched between the partitioned state and the stored state, but a simple board does not allow the space between the cage body and the ceiling to be closed in the partitioned state. Since all ventilation is blocked, indoor air stagnates on the downstream side of the partition, making it difficult to maintain cleanliness in that area.

In this regard, according to the present invention, since the partition body that can be freely switched between the partition state and the storage state has a plurality of vent holes, it has the original partition function of efficiently supplying clean air from the outlet to the cage. At the same time, it is possible to supply an appropriate amount of clean air to the downstream side of the partition, and it is possible to prevent local stagnation of indoor air, which causes a decrease in cleanliness.

[Effect of idea]

As a result of the above, the partition has the inherent effect of reducing the required amount of clean air to be blown out, and also has the advantage in handling that cages can be easily moved for purposes such as disinfecting the outside of the cage or rearranging the cage, regardless of the partition. In addition, it also has the advantage of maintaining cleanliness by preventing local stagnation of indoor air, and as a whole, we have been able to provide an animal breeding cage that is extremely practical. Ivy.

Furthermore, if the animal breeding cage according to the present invention is used, there is also the advantage that there is no need to make any improvements for partitions on the room side.
