Abstract

A tray lock mechanism for a pet enclosure is disclosed. The tray lock mechanism includes a sliding component that has a camming surface that interacts with a leading-edge of the tray to generate an upward force to move the sliding component out of the way so that the tray can be inserted into an opening and into the pet enclosure. Additionally, in a further embodiment, the tray lock mechanism contemplates a door extension that extends downward and blocks the opening when the door is in the closed position and unblocks the opening, when the door is in an opened position.

First claim

What is claimed is:

1. A method of inserting a pet tray into a pet enclosure, the method comprising:
traversing a sliding component of a tray lock mechanism disposed at a tray opening by moving the sliding component along a substantially linear path upwardly and outwardly relative to the opening with a sliding action by contact of an angled surface of the tray lock mechanism with a surface of the pet tray to permit entry of the pet tray through the opening and into the pet enclosure;
pushing the pet tray through the opening until the entire pet tray is disposed within the enclosure;
and traversing the tray lock mechanism downward to prohibit removal of the pet tray from the pet enclosure out through the opening.

2. The method of claim 1 wherein the traversing the sliding component upward comprises pushing a leading edge of the pet tray into the angled surface of the tray lock mechanism, the angled surface is configured to allow the leading edge of the pet tray to contact the angled surface to generate an upward force to traverse the sliding component of the tray lock mechanism upward.

3. The method of claim 2 wherein the angled surface is between zero degrees and 90 degrees from horizontal and vertical planes.

4. The method of claim 3 wherein the angled surface is at about 45 degrees from the horizontal and vertical planes.

5. The method of claim 1 wherein the traversing the tray lock mechanism downward to prohibit removal of the pet tray from the pet enclosure out through the opening, includes traversing the tray lock mechanism downward to enclose the pet tray entirely within the pet enclosure.
