PET DOOR ENCLOSURE SYSTEM
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 on 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.

BACKGROUNDThe embodiments disclosed herein relate to a pet door enclosure system.
Pet crates may be fabricated from a plurality of wire rods. Pet crates typically have six sides wherein top, front, back, left and right panels each have a plurality of vertical and horizontal transverse wire rods that are attached to each other. The bottom panel may also be fabricated from a plurality of transverse wire rods. A plastic or metal pan, mat or cushion may be placed on top of the bottom panel to allow the pet to comfortably sit in the pet crate. In one or more of the front, back, left or right panels, a door may be provided so that the pet can enter or exit the pet crate as desired. The door pivots about one of the vertical wire rods of the panel. To close the door, the user must pivot the door to the closed position and lock the door by way of a latch. The latch may be located on the opposite side of the pivot axis of the door or at multiple positions around the door. To lock the door, the user holds the door closed and engages the latch so that the door cannot be opened by the animal in the pet crate. To open the door the user unlocks the latch and opens the door. Unfortunately, for certain pet crates, the pet door may not be sufficiently strong for certain applications since the door is in most instances attached to a frame of the pet crate only at the pivot axis of the pet door and the latch. The upper and lower corners of the door may not be secured to the frame and could be permanently deformed when the animal pushes on the door.
Accordingly, there is a need in the art for an improved pet door enclosure system.
BRIEF SUMMARYThe door system discussed herein addresses the needs discussed above, discussed below and those that are known in the art.
The door system disclosed herein will be described in relation to a pet crate. However, the door system disclosed herein may be implemented in an animal crate for a wild animal as well as different uses. By way of example and not limitation, the door system may also be incorporated into products other than a pet crate such as a hallway gate, partition, a back door pet entry way as well as to other products and situations. However, the door system discussed herein will be discussed in relation to a pet crate for the purposes of clarity and convenience, but may be implemented in the aforementioned products and situations.
The door system may be incorporated into a pet crate. The door system may have a frame and a door. The door and frame may both be fabricated from a plurality of vertical and horizontal wire rods. The frame of the door system forms an aperture through which a pet enters and exits the pet crate. The door is attached to the frame so that the door can be pivoted to the closed position. In the closed position, the pet cannot pass through the aperture of the frame. The door can also be pivoted to the opened position so that the pet can pass through the aperture of the frame. The door may have a plurality of inverted hooks that may receive one or more of the horizontal wire rods of the frame. The inverted hooks are positioned on the door so that the door must be raised for the inverted hooks to clear the horizontal wire rod of the frame when opening or closing the door. To close the door when the door is open, the door is raised and pivoted so that the door is flush against the frame. In this position, the inverted hooks are equipped to receive the horizontal wire rods of the frame when the door is lowered. When the door is lowered, the door is now in the closed position. To lock the door, a latch is engaged to secure the door in the closed position. Beneficially, the inverted hooks may be placed at strategic locations around a periphery of the door to strengthen the door.
To open the door when the door is closed, the latch is first disengaged. Although one latch per door is shown, it is also contemplated that the door may have multiple latches positioned around the door. The door is then raised, at which time the inverted hooks can clear the horizontal wire rods of the frame. The door is now pivoted to the opened position. Accordingly, the improved door system allows convenient closure and opening of the door and also strengthens the door so that the door can withstand greater abuse by strong animals. The door can also remain closed without having to engage the latch.
More particularly, an animal door system is disclosed which comprises a frame and a door. The frame may have a plurality of interconnected vertical and horizontal wire rods with an opening at a central area of the frame for allowing an animal to pass therethrough. The door may have a plurality of interconnected vertical and horizontal wire rods. The door may be pivotally attached to a first vertical wire rod of the frame for pivoting the door between opened and closed positions. The door may have a first inverted hook which receives a first horizontal wire rod of the frame when the door is in the closed position to strengthen the animal door system.
The first and second horizontal wire rods of the door may be wrapped around the first vertical wire rod of the frame for pivotally attaching the door to the frame.
One or more hooks may be utilized. By way of example and not limitation, the first inverted hook may be located at the upper portion of the door. Also, the door may further comprise a second inverted hook attached to a lower portion of the door. Moreover, a third inverted hook may be attached between the first inverted hook and the pivot connection between the door and the frame at the upper portion of the door.
The door system may further comprise a latch attached to an opposite side of the door from the pivot axis of the door.
An opening of the inverted hook may point downward. A width of the opening of the inverted hook attached to the door may be greater than a diameter of the horizontal wire rod of the frame.
Additionally, an animal door system is disclosed which may comprise a door and a frame. The door may have a plurality of interconnected vertical and horizontal wire rods. The frame may have a plurality of interconnected vertical and horizontal wire rods containing a large opening at a central area of the frame for allowing an animal to pass threrethrough. The frame may have a first upright hook wherein the door is pivotally attached to a first vertical wire rod of the frame for pivotally opening and closing the door. The first upright hook receives a first horizontal wire rod of the door when the door is in the closed position to strengthen the animal door system.
An opening of the upright hook may point upward for receiving a wire rod of the door being lowered. A width of the opening of the upright hook attached to the frame may be greater than a diameter of the horizontal wire rod of the door.
Additionally, a method of opening and closing a door is disclosed which comprises the steps of: with the door closed, raising the door to clear a hook attached either to the door or the frame from a first horizontal wire rod of a frame or the door; pivoting the door to the opened position; and lowering the door.
The method may further comprise the steps of: with the door opened, raising the door to clear a hook attached either to the door or the frame from a first horizontal wire rod of the frame or the door; pivoting the door to the closed position; and lowering the door so that the hook attached either to the door or the frame receives the first horizontal wire rod of the frame or the door.
The hook may be an inverted hook attached to the door and raising the door clears the inverted hook attached to the door from the first horizontal wire rod of the frame. Alternatively, the hook may be an upright hook attached to the frame and raising the door clears the upright hook attached to the frame from the first horizontal wire rod of the door.
These and other features and advantages of the various embodiments disclosed herein will be better understood with respect to the following description and drawings, in which like numbers refer to like parts throughout, and in which:
