Abstract

Apparatus providing a transparent, enclosed environment for the observation and study of living things, the apparatus including an A-shaped enclosure with a selectively isolated media drawer at the base thereof and a transparent observatory mounted upon the enclosure for selective isolation of the interior of the observatory from the interior of the A-shaped enclosure.

Claims

1. Apparatus for providing an enclosed environment for living things, such as insects, for observation and study, said apparatus comprising:

a base;

a top spaced upwardly from the base;

an observation chamber having a basal area and an apical area, the basal area being substantially greater than the apical area, the chamber including

a first pair of opposite walls extending upwardly from the base toward the top and establishing a front and a back for said chamber;

a second pair of opposite walls extending upwardly from the base toward the top and establishing sides for said chamber;

the walls of at least one of said first and second pairs of opposite walls converging toward one another from the base toward the top to render the basal area substantially greater than the apical area and to establish a generally A-shaped configuration;

at least a portion of the walls of the chamber being transparent to enable the interior of the chamber to be viewed from the exterior;

a media drawer removably received within the walls, adjacent the base, the walls including wall portions surrounding the drawer, and the drawer having a peripheral configuration complementary to the configuration of the surrounding wall portions; and

first isolation means received within the chamber adjacent the drawer for selectively isolating the interior of the chamber from the interior of the drawer to enable removal of the drawer while maintaining the chamber sealed.

2. The invention of claim 1 wherein one of said first and second pairs of walls converge and the other of said first and second pairs of walls essentially are parallel to one another such that the A-shaped configuration is in two dimensions only.

3. The invention of claim 1 or 2 wherein at least one of the walls includes a flat, planar surface coincident with a transparent portion to facilitate observation through the transparent portion.

4. The invention of claim 1 or 2 wherein the basal area is at least about four times greater than the apical area.

5. The invention of claim 1 wherein the first isolation means includes a plate mounted for sliding movement immediately above the media drawer.

6. The invention of claim 1 or 5 wherein the media drawer includes a front face, a rear wall and opposite sides extending between the front face and rear wall, the opposite sides converging upwardly, similar to the converging walls of the observation chamber.

7. The invention of claim 6 wherein the media drawer is mounted between the pair of converging walls of the observation chamber for sliding movement in directions perpendicular to the front face of the media drawer.

8. The invention of claim 1 including an isolation observatory attached to one of the walls, said isolation observatory including:

an elongate housing extending between opposite ends;

an opening at one of the opposite ends;

a port in said one of the walls;

mounting means mounting the elongate housing upon the apparatus such that the opening may be placed in registration with the port; and

second isolation means for selectively isolating the interior of the housing from the interior of the observation chamber;

the housing including transparent means enabling observation of the interior of the housing.

9. The invention of claim 8 wherein:

the mounting means mounts the housing for selective movement between a first position and a second position on the apparatus, the opening being in registration with the port when the housing is in the first position; and

the second isolation means includes a partition in registration with the port when the housing is in the second position to close the port.

10. The invention of claim 9 wherein the partition is a portion of one of the walls of the chamber.

11. The invention of claim 8 wherein the transparent means includes at least one transparent plate mounted in the housing for selective removal and replacement.

12. The invention of claim 8 wherein the transparent means includes a pair of transparent plates located in opposite wall portions of the housing, the pair of transparent plates being spaced apart a relatively short distance to enable confinement of the observed insects to a readily-observed small space.

13. The invention of claim 12 wherein at least one of the transparent plates is mounted in the housing for selective removal and replacement.

14. The invention of claim 11 or 13 wherein the one transparent plate includes planar surfaces for ease of observation therethrough.
