A collapsible pet carrier includes: an interior space defined between opposing side walls, opposing end walls, a bottom wall, and a top wall. One of the walls may be opened to allow access to the interior space. An expandable rigid board is located at least partially within one the walls. In an expanded configuration of the pet carrier the board is located substantially along a length of one of the walls to provide support to the collapsible pet carrier when the collapsible pet carrier is expanded. In a collapsed configuration of the pet carrier the board extends along less than half of the length of one of the walls to allow the pet carrier to be folded along one of the opposing side walls, opposing end walls, bottom wall, and top wall.

The present invention relates to a pet litter box which prevents the surrounding environment from becoming contaminated due to excrement of a pet being exposed to the outside, comprises a main body, a cover, a door, and a multifunctional filter unit which are separably coupled, so as to easily prevent the generation of odor from the excrement of a pet and bacterial growth, and can prevent unnecessary expense increases while achieving usage convenience. The pet litter box comprises: a main body having a box shape of which an upper portion is open; a cover which is formed to be coupled to the main body so as to cover the open portion of the main body, and which is provided with a pet entrance at the front thereof, open windows on opposing left and right sides thereof to communicate with the outside, and a vent window in an upper portion thereof which forms a connecting part of the open windows, wherein a door is coupled to the pet entrance so as to be openable and closable, and a multifunctional filter unit, which has antibacterial, and odor adsorption and elimination functions, is detachably coupled to the open windows and the vent window.

A filter assembly including a rectangular inlet frame having a rectangular inlet opening configured to receive a primary filter and optionally a prefilter. The filter assembly may include a rectangular outlet frame and a housing body. The rectangular inlet frame may also be used as a housing by itself to support and house primary filters and prefilters. A gridwork including one or more grid dividers may be used in the rectangular inlet frame to provide 2 or more openings for receipt of filters.

This invention relates to a safety pet transportation device, basically in the form of a portable cage, comprising a main body, two oppositely attached side walls, at least one door, a handle and at least one safety arrangement, said main body having a bottom part, a top part with said handle and a front and a back part, wherein at least on of said front and a back part is arranged with one opening for attachment of said at least one door, and wherein, at least one of said side walls having a peripheral solid body part arranged with a plurality of safety belt holders.

A ventilation valve (1; 101) for ventilation of a space for keeping animals or plants includes an opening-defining circumferential framework (3; 103) for mounting in a wall of that space, and a movable panel (5; 105). The panel (5; 105) is movably attached to the framework (3; 103) for relative movement between a fully closed position, in which substantially no air can pass between the framework and the panel, and a fully open position, in which substantially the complete opening is available for passage of air. A profiled edge on the framework provides a non-linear relation between a passage opening and an opening position of the panel (5; 105). Also provided is a system for ventilating the space, having at least a single ventilation valve, and for periodically determining parameters of inside air in the space, and adjusting the opening position of the valve based on the parameters.

A collapsible pet carrier is provided and includes: an interior space defined between opposing side walls, opposing end walls, and a bottom wall; one or more straps attached to one of the opposing side walls and opposing end walls; a cover movably attached over a top opening of the collapsible carrier; a pair of opposing pockets located on an exterior portion of the bottom wall, the pair of opposing pockets separated by a slit; a board shaped to fit at least partially within the paid of opposing pockets and across the slit; and a closure mechanism formed along an edge of the exterior portion of the bottom wall. In an expanded configuration the board is located within both of opposing pockets. In a collapsed configuration the opposing side walls, opposing end walls, straps, and cover are folded towards the bottom wall.

A window-mounted pet litter housing is described. The housing is equipped with at least one door, a front opening, a transparent rear panel, a ceiling, a floor, and at least one window anchor mount. The front opening facilitates access to the housing by the pet. The interior of the housing provides adequate space for the pet litter box, as well as space for the pet to lie down and peer through the transparent rear panel. Vented louvers are disposed in the left wall and right wall which provide ventilation while preventing rain and snow from entering the housing. A mounting plate present in the preferred embodiment expedites and facilitates secure installation of the housing from inside the structure equipped with the window.

A sidewall inlet that assists in bringing fresh air into the interior room of a building. The inlet housing provides an opening to the interior room of a building through a rough opening, with the housing having a design to mount flush to the interior sidewall of the room and covering many size variations of rough openings. The housing of the inlet consisting of a frame assembly and a blade assembly that allows the inlet to be constructed to fit various lengths of rough openings and provide the proper air mixture needed in a building. The inlet having a moveable blade is pivotally mounted with a continuous hinge and a seal on the top frame to minimize air leakage when the inlet is closed. The housing is designed in such a way to provide optimal air mixture and to maximize airflow during ventilation.

A pet crate door latch with a vertically-reciprocating slider on the door and fixed tabs attached to a crate side panel adjacent to the door opening and forming open slots parallel to the panel. The slots can be vertical, inwardly-facing horizontal, or outwardly-facing horizontal. The slider has perpendicular or parallel edges that operate as slot edges. The perpendicular edges are slot edges for vertical slots and the parallel edges are slot edges for horizontal slots. There is a tab space below each slot edge. To engage the latch, the slider is raised until the tabs are aligned with the associated tab spaces. As the door is closing, the tabs fit through the tab spaces. When the door is closed, the slider is lowered until halted by a latch stop wherein the slot edge is transversely within the slot.

A box for transporting live animals, particularly of the type of laboratory mice and/or rats, which comprises a base, four side walls and a lid, at least one of the side walls comprising at least one opening for ventilating the internal volume of the box, a protective mesh made of a material such as metal being associated with the at least one opening; the base and the four side walls are made of a material such as polypropylene.
