"Cage for small animals"

The invention relates to a cage for small animals, with several breeding box levels arranged one above the other, each floor has several breeding boxes lined up in a row.

When accommodating small animals such as rats, mice or the like. during rearing or especially for test and the purpose of investigation is often one against disruptive ones (Closed) animal reception protected from environmental influences required.

INSPECTED

So far it has been customary in such cases to put the small animals in separate boxes with light and / or air-impermeable boxes To accommodate walls, these boxes arranged next to and / or at a distance one above the other could be. With this kind of animal husbandry, however, there is the great disadvantage of inadequate handling and ventilation, as the air enriched with vapors accumulates in every animal box - an odor-reduced one and hygienic animal husbandry is only possible to a limited extent.

The small animal cages with light and air permeable, which have become known in various embodiments Walls ensure adequate ventilation, but are construction-related for one Keeping animals shielded from the outside world is unsuitable. In addition, they often have the other Disadvantage of a complicated and / or only partially variable structure.

The task of the invention is to create a simply structured To create a cage for small animals with several rows which, even when the animal husbandry is largely closed off from the outside world, always has sufficient and ventilation is guaranteed.

According to the invention, a cage for small animals with several breeding box levels arranged one above the other, the individual tier of which is composed of several breeding boxes lined up in a row, characterized in that, that between the cage wall and the individual breeding box levels radial, in at least one shaft,

de ventilation ducts are provided.

In a preferred embodiment, the ventilation channels are arranged parallel and at right angles to the longitudinal axis of the breeding boxes and floors. A central shaft running on the cage axis and extending over the entire height of the cage has a throughflow opening in each floor level in the area, preferably of each animal cell. Advantageously, the breeding boxes are surrounded by an annular channel d on the outside wall, which also extends over the entire height of the cage. Since the spaces between the individual floors, which act as ventilation channels, are connected to the inner and outer vertical air shaft, good ventilation of the entire interior and thus of each animal cell is ensured.

In a further preferred embodiment, a hollow column is formed on the longitudinal axis of the cage for the breeding box levels arranged one above the other, which is formed from a plurality of spacers which can be plugged into one another, preferably in the form of tubes. The Ab- (

Stand pieces are advantageously equipped with radial flow openings and at the same time all Carrying device provided for the breeding boxes arranged thereon.

According to another preferred feature of the invention is bssw. Bind above and / or below the hollow pillar fans formed by the breeding box floors are provided, which ensure an advantageous air circulation.

Furthermore, it can be advantageous to arrange the supporting frame rotatably on a base plate or stand, so that the operator, without changing his position, always by rotating the small animal cage can reach a certain number of breeding boxes.

A small animal cage designed according to the invention with separate animal cells is characterized by simple, according to the requirements variable (expandable or demountable) structure due to its advantageous Ventilation and ventilation of the cage interior. The fresh air brought in moves from down on the inner wall vertically upwards and at the same time pulls through the channels between the individual floors towards the central hollow column,. through which the used air then sweeps upwards and is sucked out of the cage by a fan arranged in its upper end area. This arrangement the ventilation and / or ventilation ducts ensure good ventilation and / or ventilation of the individual floors, with the rising of the fresh air on the inside of the cage outer wall with subsequent painting every floor is also supplied with enough fresh air and the air introduced in a simple way is discharged through the central hollow column.

The ventilation of the cage according to the invention is simple, practical and good. Due to the advantageous Arrangement of the individual channels is the darkness and thus the breeding process or the like. not through external influences impaired. The hollow column (central column) formed by the individual floors continues to show the
