Abstract

This invention relates to a vivarium for keeping, raising, and/or observing animals or plants. The present invention provides a vivarium comprised of a generally rectangular tank having four side walls and a base. A pair of guide tracks extend generally along the upper edge of two of the side walls. A cover is provided which slides horizontally onto the vivarium along the guide tracks. A stop along one edge of the cover engages a clip, hanging over one of the side walls of the vivarium, when the cover is in a closed position. When the stop has engaged the clip, a locking pin may be inserted through the stop to prevent the unauthorized access to the interior of the vivarium.

Claims

1. A vivarium having an interior, comprising:

a tank having a plurality of side walls and a base, each side wall having an upper edge opposite to the base;

a cover;

a pair of guide tracks extending generally parallel along the upper edge of a first and a second of the side walls for receiving the cover in a horizontal sliding relation, the cover slidable between a first open position to allow access to the interior of the vivarium and a second closed position so as to prevent access to the interior of the vivarium; and

means for maintaining the cover in the closed position;

wherein the means for maintaining the cover in the closed position is comprised of;

a stop attached to an edge of the cover in a plane perpendicular to the guide tracks; and

a clip hanging over an edge of a third of the side walls and between the guide tracks, said stop being retainable in said clip;

wherein the clip is further comprised of a hanging member affixed to the third of the side walls and a downward sloping ramp extending away from the third of the side walls on which the clip is hung, the hanging member and the ramp defining a recess for receipt of the stop when the cover is in the closed position;

wherein the clip is further comprised of an aperture extending downwardly through the ramp of the clip for receipt of a locking pin such that the locking pin prevents the removal of the stop from the recess when the locking pin engages the clip.

2. A vivarium having an interior, comprising:

a tank having a plurality of side walls and a base, each side wall having an upper edge opposite to the base;

a cover;

a pair of guide tracks extending generally parallel along the upper edge of a first and a second of the side walls for receiving the cover in a horizontal sliding relation, the cover slidable between a first open position to allow access to the interior of the vivarium and a second closed position so as to prevent access to the interior of the vivarium; and

means for maintaining the cover in the closed position;

wherein the means for maintaining the cover in the closed position is comprised of;

a stop attached to an edge of the cover in a plane perpendicular to the guide tracks; and

a clip hanging over an edge of a third of the side walls and between the guide tracks, said stop being retainable in said clip;

wherein the clip is further comprised of a hanging member affixed to the third of the side walls and a downward sloping ramp extending away from the third of the side walls on which the clip is hung, the hanging member and the ramp defining a recess for receipt of the stop when the cover is in the closed position;

wherein the clip is further comprised of an aperture extending downwardly through the ramp of the clip for receipt of a locking pin such that the locking pin prevents the removal of the stop from the recess when the locking pin engages the clip;

wherein said locking pin includes a means for receiving a lock locked thereto while the locking pin engages the clip to prevent removal of said locking pin, to in turn maintain the cover in the closed position.

3. A vivarium comprising:

a tank having a plurality of side walls and a base, each side wall having an upper edge opposite to the base;

a pair of guide tracks extending generally parallel along the upper edge of a first and a second of the side walls, each guide track having a lip extending therealong, each lip of each guide track directed toward the other guide track;

a cover comprised of a border extending partially around a screen, the border having two generally parallel grooves extending longitudinally along opposite sides of the cover for receipt of the lips such that the cover may slide along the lips in a horizontal relation between a first open position to allow access to the interior of the vivarium and a second closed position so as to prevent access to the interior of the vivarium;

a stop affixed to an edge of the cover, the edge extending generally perpendicular to the grooves;

a clip hanging over an edge of a third of the side walls and between each of the guide tracks, the clip being comprised of a hanging member for hanging the clip over the edge of the third of the side walls and a downward sloping ramp extending away from the third of the side walls on which the clip is hung, the hanging member and the ramp defining a recess for receipt of the stop when the cover is in the closed position; and

a locking pin secured on the ramp so as to maintain the cover in the closed position.

4. The device of claim 3 further comprising a third guide track extending along the upper edge of a fourth of the side walls opposite to the third of the side walls on which the clip hangs, the third guide track being generally perpendicular to the pair of generally parallel guide tracks.
