Abstract

An animal enclosure including a plurality of members defining an interior of the enclosure. The plurality of members includes a first member having a frame and a door formed by a plurality of interconnected horizontal and vertical wires. The door is pivotable with respect to the frame and a latch maintains the door in a closed position when latched. At least one of the wires of the door assembly is configured to include one of an access portion and a tab, and at least one of the wires of the frame assembly includes the other of the access portion and the tab. The latch, when moved to an open position, enables sliding movement of the door with respect to the frame. Alignment of the access portion and tab provides for opening of the door and pivoting movement of the door with respect to the frame.

Claims (36)

1 . An animal enclosure, comprising:

a plurality of members defining an interior of the enclosure, where the plurality of members includes at least a first member;

a frame of the first member having a plurality of interconnected horizontal and vertical wires that define an opening for an animal to pass therethrough and to enter or exit the interior of the enclosure;

a door of the first member having a plurality of interconnected horizontal and vertical wires and being coupled to the frame, the door being pivotal about a pivot wire of the frame to move between an open position, an intermediate position, and a closed position; and

a door stop comprising an access portion, a blocking portion, and a tab, where the tab is fixedly coupled to the door and the access portion and blocking portion are formed by the frame;

wherein, an alignment of the tab and the blocking portion at a first position of the door enables pivotal movement of the door with respect to the frame from the closed position to the intermediate position and the blocking portion contacts the tab to limit pivotal movement of the door to the open position, and wherein in a second position of the door enables pivotal movement of the door with respect to the frame from the intermediate position to the open position.

2 . The animal enclosure of claim 1 wherein, during a sliding movement of the door with respect to the frame, the door is located at a position between the first position and the second position.

3 . The animal enclosure of claim 1 wherein the blocking portion comprises a blocking tab, wherein the blocking tab extends from a plane defined by the frame.

4 . The animal enclosure of claim 1 wherein the blocking portion comprises a blocking tab, wherein the blocking tab is at least partially formed by a first bend including an inside surface formed outside the tab when in the closed position.

5 . The animal enclosure of claim 1 further comprising an extension configured to limit pivotable movement of the door to the interior of the enclosure.

6 . The animal enclosure of claim 5 wherein the extension is formed by one of the plurality of interconnected wires of the door.

7 . The animal enclosure of claim 5 wherein the extension is coupled to the frame.

8 . An animal enclosure, comprising:

a plurality of members defining an interior of the enclosure, where the plurality of members includes at least a first member;

a frame of the first member having a plurality of interconnected horizontal and vertical wires that define an opening for an animal to pass therethrough and to enter or exit the interior of the enclosure;

a door of the first member having a plurality of interconnected horizontal and vertical wires and being coupled to the frame, the door being pivotal about a pivot wire of the frame to move between an open position and a closed position; and

a door stop comprising an access portion, a blocking portion, and a tab, where the tab is fixedly coupled to the door and the access portion and blocking portion are formed by the frame;

wherein, in a first position, the tab is in alignment between a first portion and a second portion of the blocking portion, and the tab is configured to move a first distance as the door pivots relative to the frame;

wherein, in a second position, the tab is in alignment with the access portion such that the tab is configured to move a second distance as the door pivots relative to the frame to the open position, where the second distance is greater than the first distance.

9 . The animal enclosure of claim 8 wherein the blocking portion comprises a blocking tab wherein the blocking tab extends from a plane defined by the frame.

10 . The animal enclosure of claim 8 wherein sliding movement of the door with respect to the frame positions the door between the first position and the second position.

11 . An animal enclosure, comprising:

a plurality of members defining an interior of the enclosure, where the plurality of members includes at least a first member;

a frame of the first member having a plurality of interconnected horizontal and vertical wires that define an opening for an animal to pass therethrough and to enter or exit the interior of the enclosure;

a door of the first member having a plurality of interconnected horizontal and vertical wires and being coupled to the frame, the door being pivotal about a pivot wire of the frame to move between an open position and a closed position; and

a retainer coupled to the frame;

wherein, in a first position of the door, one of the plurality of wires of the door engages the retainer to limit pivotable movement of the door from the closed position, and wherein in a second position of the door, the one of the plurality of wires of the door is disengaged from the retainer to enable the door to pivot from the closed position to the open position.

12 . The animal enclosure of claim 11 wherein the retainer comprises a hook, in which the one of the plurality of wires of the door engages in the closed position and the one of the plurality of wires is disengaged in the open position.

13 . The animal enclosure of claim 11 further comprising a latch assembly including a moveable latch selectively configured to move between a latched position and an unlatched position.

14 . The animal enclosure of claim 11 wherein the one of the plurality of wires of the door is a top wire of the door.

15 . The animal enclosure of claim 14 wherein the top wire of the door is a horizontal wire of the door.

16 . The animal enclosure of claim 11 further comprising a doorstop including an access portion, a blocking portion, and a tab, wherein the blocking portion limits pivotable movement when in the first position of the door.

17 . The animal enclosure of claim 16 wherein the access portion and the blocking portion are formed by the door.

18 . The animal enclosure of claim 16 wherein the frame includes the access portion and the blocking portion.

19 . The animal enclosure of claim 16 wherein the tab extends away from a plane defined by the door.

20 . The animal enclosure of claim 16 wherein the tab is configured to move through the access portion or the access portion is configured to move such that the tab is passed therethrough during pivoting movement of the door with respect to the frame when the tab is aligned with the access portion.
