BACKGROUND

The present invention relates generally to structures for housing animals and more particularly to portable pet kennels and pet crates. In some embodiments, the present invention relates to portable pet crates for housing or transporting dogs.

Various types of structural enclosures for storing and transporting animals are known in the art. Conventional portable animal crates such as those used for housing and transporting dogs typically include a plastic or metal wire construction and include an interior enclosure with a selectively openable door. Conventional portable animal crates generally include a single-layer construction such as a single layer of plastic, metal or wire mesh. The single-layer material forms the structural support and also defines the enclosure space within the interior of the crate. Conventional single-layer animal crates of this type are generally sized to easily fit in the bed of a truck or the cargo area of a sport-utility vehicle, and such crates are often used by sportsmen, disabled persons, rescue, military and/or law enforcement personnel for storing and transporting dogs. Such conventional portable animal crates provide a benefit of being relatively lightweight and portable such that a single person can lift and move the crate. Additionally, these types of conventional animal crates are generally sized to accommodate only the animal or animals to be housed within, thereby enhancing the portable nature of the product.

One problem with conventional animal crates is the door. Traditional doors for portable animal crates often include a spring-loaded latch that includes one or more posts that extend through a corresponding hole in the crate. Conventional doors for animal crates are also hinged between opposing posts on the opposite side of the door from the latch directly to the crate wall. Such conventional animal crate doors are often difficult to open and close, are susceptible to breakage during use, and are insufficient to retain an animal in the crate during an accident or during transport.

What is needed, then, are improvements to animal enclosures and specifically door assemblies for animal enclosures to address these and other problems.

A person of skill in the art will recognize that the apparatus can assume different orientations when in use.

Referring now to FIG. 1, an embodiment of an animal enclosure apparatus 10 is shown. The size and shape of kennel 10 allows kennel 10 to be easily transported from a residence or building to a vehicle or other mode of transportation. Additionally, in some embodiments, kennel 10 is portable and is shaped and sized to comply with one or more regulations for traveling with pets on commercial airlines.

The animal enclosure apparatus 10, kennel, or animal crate, includes a kennel body having an upper housing member 12 and a lower housing member 14 in some embodiments, as shown in FIG. 1 and FIG. 2. In other embodiments, animal enclosure apparatus 10 includes a kennel body formed as a single piece.

In some embodiments, animal enclosure 10 includes a door opening 16 as shown in FIG. 2. Door opening 16 provides an opening for allowing animals to enter and exit the animal enclosure. As shown in FIG. 3, a door assembly 18 is disposed in door opening 16. The door assembly 18 includes a door frame 20 and a door 22 mounted on the door frame at a pivoting door hinge 24. The door frame 22 may be secured to the kennel body 12, 14 at the door opening 16 using one or more door frame fasteners 30, shown in FIG. 2. During use, the door 22 may be opened and closed relative to the kennel body and door frame 20. Door 22 is pivotally attached to door frame 20, and the door frame 20 stays attached to the kennel body via one or more door frame fasteners 30 as the door 22 is opened and closed.

Door 22 is moveable between a closed position, as seen in FIG. 1 and an open position, as seen in FIG. 7. Door 22 may be secured in the closed position using one or more latches. For example, as seen in FIG. 1, door assembly 18 includes a door 22 having a first latch 26, a second latch 36, and a third latch 56. Each latch provides an engagement between the door 22 and the door frame 20 to secure the door in a closed position. By releasing first latch 26, second latch 36 and third latch 56, a user may open door 22 to allow an animal to enter or exit the animal enclosure 10. A user may utilize only one latch, two latches or all three latches to secure the door 22 in a closed position. Each latch is generally moveable between a locked position and an unlocked position.

As shown in FIG. 3, in some embodiments, the door assembly 18 includes a door frame 20 and a door 22 mounted on door frame 20 via a pivoting hinge 24. Door 22 is angularly moveable relative to door frame 20 about hinge 24. First latch 26 includes a first latch handle 32 that a user may grasp to activate first latch 26. First latch handle 32 may include any suitable control for activating first latch 26, such as but not limited to a knob or a lever. Similarly, second latch 36 includes a second latch handle 42 that a user may grasp to activate second latch 36. Second latch handle may include any suitable control for activating second latch 36, such as but not limited to a knob or a lever. Third latch 56 includes a third latch handle 62 that a user may grasp to activate third latch 56. Third latch handle 62 may include any suitable control for activating third latch 56, such as but not limited to a knob or a lever.

As shown in FIG. 4, each latch includes a corresponding bolt that engages the door frame to secure the latch in a closed position. For example, first latch 26 includes a first latch bolt 34 that extends back and forth from the door toward the door frame when the first latch 26 is activated by a user. First latch bolt 34 extends and retracts in a substantially horizontal orientation in some embodiments. Second latch 36 includes a second latch bolt 44 extending back and forth from door 22 relative to the frame when the second latch 36 is activated by a user. Second latch bolt 44 extends and retracts in a substantially vertical orientation in some embodiments. Third latch 56 includes a third latch bolt 54 extending back and forth from the door 22 toward the door frame when the third latch 56 is activated by a user. Third latch bolt 54 extends and retracts in a substantially vertical orientation in some embodiments. Additionally, in some embodiments, second latch bolt 44 and third latch bolt 54 each extend and retract along a common vertical reference axis, and first latch bolt 34 extends and retracts along a substantially horizontal reference axis perpendicular to the vertical reference axis in some embodiments.

Each latch includes a latch handle that a user can grasp to operate the latch. As shown in FIG. 5, an exemplary embodiment of a second latch 36 includes a second latch handle 42. Second latch handle 42 extends from the face of door 22 and provides a structure for a user to manipulate to activate second latch 36. In this embodiment, second latch handle 42 includes a knob that is moveable up and down along a second latch track defined in door 22. Second latch handle 42 operates second latch bolt 44 between an unlocked position and a locked position, as seen in FIG. 6. In the locked position, second latch bolt 44 engages door frame 20 at a second latch location 38. Second latch location 38 is defined along top frame section 70 on frame 22 in some embodiments. As shown in FIG. 6, second latch bolt 44 slides upwardly toward frame 20, when second latch handle 42 is operated while the door 22 is in a closed position. Second latch bolt 44 may be slid into a local opening, or second latch recess 50, defined in frame 20. Second latch recess 50 defines a space shaped to accommodate a portion of second latch bolt 44. When second latch bolt 44 is received in second latch recess 50, second latch bolt 44 interferes mechanically with frame 20 in the event door 22 is attempted to be opened. In this capacity, second latch bolt 44 operates as a lock to prevent door 22 from being opened relative to frame 20. When second latch 36 is released by sliding second latch handle 42 away from frame 20, second latch bolt 44 retracts from second latch recess 50 and moves to an unlocked position. Second latch 36 may be operated independently of first latch 26 and third latch 56.

As seen in FIG. 7, additional latches may be positioned on the door 22. For example, third latch 56 includes a third latch bolt 54 protruding from door 22 toward frame 20. As shown in FIGS. 12 and 13, an exemplary embodiment of a third latch 56 includes a third latch handle 62. Third latch handle 62 extends from the face of door 22 and provides a structure for a user to manipulate to activate third latch 56. In this embodiment, third latch handle 62 includes a knob that is moveable up and down along a third latch track defined in door 22. Third latch handle 62 operates third latch bolt 54 between an unlocked position and a locked position, as seen in FIG. 13. In the locked position, third latch bolt 54 engages door frame 20 at a third latch location 58. Third latch location 58 is defined along bottom frame section 72 on frame 22 in some embodiments. As shown in FIG. 13, third latch bolt 54 slides downwardly toward frame 20, when third latch handle 62 is operated while the door 22 is in a closed position. Third latch bolt 54 may be slid into a local opening, or third latch recess 60, defined in frame 20. Third latch recess 60 defines a space shaped to accommodate a portion of third latch bolt 54. When third latch bolt 54 is received in third latch recess 60, third latch bolt 54 interferes mechanically with frame 20 in the event door 22 is attempted to be opened. In this capacity, third latch bolt 54 operates as a lock to prevent door 22 from being opened relative to frame 20. When third latch 56 is released by sliding third latch handle 62 away from frame 20, third latch bolt 54 retracts from third latch recess 60 and moves to an unlocked position. Third latch 56 may be operated independently of first latch 26 and second latch 36.

In some embodiments, it is suitable to use first latch 26 as the only latch to secure door 22 in a closed position relative to door frame 20. A user may selectively open first latch 26, causing first latch bolt 34 to disengage from door frame 22 or from a strike plate 78 on door frame 20. A user may then close door 22 using only first latch 26 and first latch bolt 34 to engage a corresponding first latch location on door frame 22 or strike plate 78.

However, in other applications it is beneficial for door 22 to be more securely latched to frame 22 at more than one location to prevent door 22 from inadvertently opening during use. For example, while transporting an animal inside the enclosure 10 it is desirable to include multiple latches between door 22 and door frame 20 to achieve a better engagement between door 22 and frame 20. As shown in FIG. 8, in some embodiments the placement of the first latch 26, second latch 36 and third latch 56 provides an improved securement between the door 22 and door frame 20.

As shown in FIGS. 8-11, in some embodiments, door frame 20 includes a hoop-shaped structure including a top frame section 70 positioned along the top edge of the door frame, a bottom frame section 72 positioned along the bottom edge of the door frame, a latch side frame section 74 positioned on the side of the door frame where first latch 26 engages the door frame, and a hinge side frame section 76 positioned on the side of the door frame where the hinge between the door and the door frame is located. In some embodiments, first latch 26 includes a first latch bolt 34 engaging the door frame 22 at a first latch location 28 on the latch side frame section 74. The second latch 36 includes a second latch bolt 44 engaging the door frame 22 at a second latch location 38 on the top frame section 70. The third latch 56 includes a third latch bolt 54 engaging the door frame 22 at a third latch location 58 on the bottom frame section 72. In some configurations, first latch bolt 34 is equidistant between the second latch bolt 44 and the third latch bolt 54.

First latch 26 includes a first latch bolt 34 that is moveable between a locked position and an unlocked position. When first latch bolt 34 is in a locked, or closed, position, first latch bolt 34 engages a corresponding structure on frame 20 at first latch location 28. For example, as shown in FIG. 11, a first latch recess 40 is defined in frame 20. First latch recess 40 defines a space where first latch bolt 34 is received when first latch 26 is in a locked position. As such, when door 22 is closed relative to frame 22, first latch bolt 34 extends partially into first latch recess 40 and provides a mechanical interference with frame 20 in the event door 22 is pushed or pulled, thereby keeping door 22 in a closed position. When first latch 26 is manipulated by a user to an open, or unlocked, position, first latch bolt 34 retracts from first latch recess 40 and allows door 22 to be opened relative to frame 20.

In some embodiments, a strike plate 78 is positioned on frame 20. Strike plate 78 includes a flat plate having a central opening. First latch bolt 34 partially extends through the central opening in strike plate 78 to achieve an engagement suitable to hold door 22 in a closed position relative to frame 20.

As shown in FIG. 1 and FIG. 3, door assembly 18 is oriented such that the first latch 26 is generally oriented on the right hand side of the animal enclosure 10 when viewing the animal enclosure 10 from the front. When oriented in this configuration, the door 22 and frame 20 are positioned in an upright orientation as seen in FIG. 3 with first latch 26 on the right side and hinge 24 on the left side of the kennel body. Because first latch bolt 34, second latch bolt 44 and third latch bolt 54 all engage frame 20, none of the latch bolt engagements require a specific engagement location on the kennel body around the perimeter of opening 16. As such, the door assembly 18 of the present disclosure may be rotated one-hundred-eighty degrees such that first latch 26 is on the left side of door assembly 18 for mounting on the kennel body, as shown in FIG. 9 and FIG. 10. This unique feature of the door assembly 18 allows the door assembly 18 to retain three latch locations in with first latch 26 on the right side for a right hand open as shown in FIG. 1 or on the left side for a left hand open as shown in FIG. 10.

In some embodiments, first latch 26 includes a biasing member such that first latch bolt 34 is biased toward first latch recess 40 when door 22 is in a closed position. Additionally, second and third latches 36, 56 are not biased in either an open or closed configuration in some embodiments. For example, when second latch 36 is in an unlocked position, second latch bolt 44 is fully retracted from second latch recess 50, as shown in FIGS. 14 and 15. If a user engages second latch handle 42 and presses it toward frame 20, then second latch bolt 44 travels toward and enters second latch recess 50, placing second latch 36 in a locked position. Second latch 36 will remain in a locked position until a user manually engages second latch handle 42 and slides it away from frame 20, retracting second latch bolt 44 from second latch recess 50, and placing second latch 36 back in an unlocked position.

Similarly, when third latch 56 is in an unlocked position, third latch bolt 54 is fully retracted from third latch recess 60. If a user engages third latch handle 62 and presses it toward frame 20, then third latch bolt 54 travels toward and enters third latch recess 60, placing third latch 56 in a locked position. Third latch 56 will remain in a locked position until a user manually engages third latch handle 62 and slides it away from frame 20, retracting third latch bolt 54 from third latch recess 60, an placing third latch 56 back in an unlocked position.

Thus, although there have been described particular embodiments of the present invention of a new and useful ANIMAL ENCLOSURE AND DOOR ASSEMBLY, it is not intended that such references be construed as limitations upon the scope of this invention.
