Abstract

The door system disclosed herein includes a frame and a door fabricated from a plurality of horizontal and vertical wire rods. The door may have an inverted hook which is aligned to a horizontal wire rod of the frame when the door is pivoted to the closed position. To close the door, the door is dropped so that the horizontal wire rod of the frame is traversed into the inverted hook. At this point, the animal inside of the pet crate cannot open the door by pushing the door. Rather, the door must be raised so that the inverted hook clears the horizontal wire rod of the frame to pivot the door to the opened position.

First claim

What is claimed is:

1. An animal enclosure comprising:
a panel having a first horizontal wire, a second horizontal wire, a third horizontal wire, a first vertical wire extending between the first and second horizontal wires of the panel, a second vertical wire extending between the first and second horizontal wires of the panel, and a third vertical wire directly adjacent to the second vertical wire, the first and second vertical wires of the panel and the first and second horizontal wires of the panel forming a perimeter of an opening in the panel sized and configured to enable an animal to pass therethrough, the third vertical wire of the panel being disposed outside of the opening in the panel, and the third horizontal wire extending only between the second and third vertical wires of the panel so as to be entirely disposed outside the opening in the panel;
a door having a plurality of horizontal wires, including at least an upper horizontal wire, a lower horizontal wire, and a third horizontal wire, a first vertical wire, a second vertical wire, and a third vertical wire directly adjacent the second vertical wire, each of the first and second vertical wires extending between the upper and lower horizontal wires of the door so as to define an outer perimeter of the door, each of the upper horizontal wire and the lower horizontal wire of the door being pivotally attached to the first vertical wire of the panel so that the door is pivotal between a closed position and an open position, and attached so that the door is vertically movable between a latched position and an unlatched position, and at least the upper horizontal wire, the lower horizontal wire and the second vertical wire of the door being disposed such the door defines an area that is larger than an area of the opening in the panel such that at least three sides of the door extend beyond the opening in the panel to overlap the panel, and the third horizontal wire of the door being disposed substantially midway between two of the plurality of horizontal wires and extending between and delimited by the second and third vertical wires of the door so as to be substantially disposed in an area outside of the opening in the panel and within the outer perimeter of the door when the door is in the closed position;
a first hook having a first end and a second end, the first end attached to one of the plurality of horizontal wires of the door and the second end including first and second elements that define a u-shape portion having a hook interior, the second end attached to the third horizontal wire of the door such that the first hook is entirely within the perimeter of the door and the third horizontal wire of the door extends through the hook interior, and the first hook configured to engage the third horizontal wire of the panel adjacent the second vertical wire of the panel in the area outside of the opening in the panel when the door is in the closed position and the latched position, such that the third horizontal wire of the panel extends through the hook interior and the first hook is entirely disposed outside of the opening in the panel when the door is in the closed position;
a second hook attached to the first horizontal wire of the door and configured to engage the first horizontal wire of the panel adjacent the first vertical wire of the panel when the door is in the closed position and the latched position;
a third hook attached to the second horizontal wire of the door and configured to engage the second horizontal wire of the panel adjacent the first vertical wire of the panel when the door is in the closed position and the latched position;
a fourth hook attached to the second horizontal wire of the door and configured to engage the second horizontal wire of the panel adjacent the second vertical wire of the panel when the door is in the closed position and the latched position; and
a latch attached to the door, the latch configured to move in a horizontal direction and engage the second vertical wire of the panel,
the second hook, the third hook and the fourth hook are disposed entirely within the perimeter of the door and configured to engage one of the first and second horizontal wires of the panel adjacent the first and second vertical wires of the panel forming the perimeter of the opening in the panel to secure the door in the closed position, and the first hook, the second hook, the third hook and the fourth hook being vertically movable between the latched position and the unlatched position.

2. The animal enclosure recited in claim 1 , wherein
each of the first, second, third and fourth hooks are configured to disengage from a respective horizontal wire of the panel when the door is moved from the latched position to the unlatched position.

3. The animal enclosure recited in claim 1 , wherein
the door has a first side and a second side opposite the first side, the first side is disposed against the panel when the door is in the closed position, and each of the first, second, third and fourth hooks are attached to the door at the first side.

4. The animal enclosure recited in claim 1 , wherein
the second horizontal wire of the door is configured to be disposed at least partly within the opening in the panel when the door is in the closed position, and the first horizontal wire of the door is configured to be disposed completely outside the opening in the panel when the door is in the closed position.

5. The animal enclosure recited in claim 1 , wherein
the latch is disposed on a side of the door opposite a side in which each of the first horizontal wire of the door and the second horizontal wire of the door are pivotally attached to the first vertical wire of the panel.

6. The animal enclosure recited in claim 1 , wherein
each of the first, second, third and fourth hooks have an arcuate portion and a respective horizontal wire of the panel is disposed within the arcuate portion when the door is in the closed and latched position.

7. The animal enclosure recited in claim 1 , wherein
each of the first, second, third and fourth hooks has a first vertical portion and a second vertical portion, each of the first and second vertical portions being attached to the door.

8. The animal enclosure recited in claim 1 , wherein
the latch is rotatable about a longitudinal axis.

9. The animal enclosure recited in claim 1 , further comprising
a handle configured to enable the door to move in the vertical direction.

10. The animal enclosure recited in claim 9 , wherein
the handle is attached to the latch, and is configured to enable the latch to rotate about a longitudinal axis.

11. The animal enclosure recited in claim 1 , wherein
the first hook is disposed outside of the perimeter of the opening in the panel when the door is in the closed position and the latched position.

12. An animal enclosure comprising:
a panel having a first horizontal wire, a second horizontal wire, a first vertical wire extending between the first and second horizontal wires of the panel, a second vertical wire extending between the first and second horizontal wires of the panel, the first and second vertical wires of the panel and the first and second horizontal wires of the panel forming a perimeter of an opening in the panel sized and configured to enable an animal to pass therethrough;
a door having a plurality of horizontal wires, including at least an upper horizontal wire, an intermediate horizontal wire and a lower horizontal wire, a first vertical wire, and a second vertical wire, each of the first and second vertical wires extending between the upper and lower horizontal wires of the door so as to define an ou
