  • Patent number: 9434338
    Abstract: A connector for use with an animal barrier. The connector includes a locking member configured to lock corresponding horizontal and vertical members when the locking member is in the locked position, and release the corresponding horizontal and vertical members to allow for length adjustment of both the horizontal and vertical members when the s is in the release position.

  • Patent number: 9399886
    Abstract: A camming member for a door may have a camming surface which lifts the door as the door is traversed from an opened position to a closed position. The lifting movement of the door caused by the camming member facilitates one or more latches used to reinforce a periphery of the door to be engaged without further user intervention.

  • Publication number: 20160205890
    Abstract: A latching mechanism having a camming surface to engage the latching mechanism without human intervention when a door is traversed from an opened position to a closed position is disclosed. Other latching mechanisms are also disclosed. The latching mechanism may also be rotatable to engage the latching mechanism and prevent opening of the door from the closed position.

  • Publication number: 20160120145
    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.

  • Publication number: 20160014996
    Abstract: A door for a pet enclosure is disclosed herein. The door is vertically and rotatably traversable with dual axes connectors. The door may be vertically traversed to unlatch hooks and wire rods from each other so that the door may thereafter be rotatably traversed to the opened position where the door is disposed on top of the top panel.

  • Publication number: 20150232052
    Abstract: A connector for use with an animal barrier. The connector includes a locking member configured to lock corresponding horizontal and vertical members when the locking member is in the locked position, and release the corresponding horizontal and vertical members to allow for length adjustment of both the horizontal and vertical members when the s is in the release position. Therefore, separate s are not needed for the corresponding horizontal and vertical members. Thus, the connector simplifies adjustment of the animal barrier to allow the animal barrier to be easily adapted to the specific size of the vehicle.

  • Publication number: 20140174375
    Abstract: A dual axes swivel connector for connecting various panels to assemble a pet enclosure is disclosed. The dual axes swivel connector allows panels of the enclosure to be reliably pivoted with respect to each other. The dual axes swivel connector may comprise first and second parts. The first part may be fabricated from a flexible material compared to the second part, whereas the second part may be fabricated from a more rigid material compared to the first part. The flexibility of the first part allows the first part to have a tighter fit with the wire rods. The second part has a looser fit with the wire rods but the rigidity of the second part compensates for the looser fit. When the first and second parts are interlocked, they create a tight fit which can reliably provide a hinge between the panels.

  • Publication number: 20120227675
    Abstract: A dual axes swivel connector for connecting various panels to assemble a pet enclosure is disclosed. The dual axes swivel connector allows panels of the enclosure to be reliably pivoted with respect to each other. Additionally, the dual axes swivel connector allows the various panels of the enclosure to be offset with respect to each other when the enclosure is traversed to the collapsed position. The offset permits and enables the stacking of the various panels on top of each other. The dual axes swivel connector may be fabricated from a plastic material whereas the panels of the enclosure may be fabricated from a metallic material to reduce vibration noise.
