A protective screen system and method of installation for preventing bugs and insects from passing through a door or window opening, as well as preventing pets, such as dogs and cats from causing damage to a protective screen. The system and method include removing an existing screen from a door or window frame and inserting a protective screen member through a front face of the frame. The protective screen member is a rigid, transparent panel having a plurality of spaced apertures forming a grid pattern. The protective screen member is positioned through an opening of the frame and within a groove thereof such that an entire outer perimeter of the protective screen member is seated within the door or window frame. The protective screen member is secured to the frame via application of a fastener such as an adhesive or tape.

In order to prevent condensation from forming on a surface of an inner gasket surrounded on a rear surface of an indoor side door of an entrance refrigerator, the entrance refrigerator has a flow passage structure in which a portion of indoor air, whose temperature is increased by heat exchange with a heat sink, flows along the surface of the inner gasket.

An automated gate for robotic mowers may include at least two doors that are sized to receive a robotic mower, and it can be installed in any fence to enable the mower to move between the yards on its own. The at least two doors of an automated gate may provide optional capability to lock when not used by the mower and unlock automatically when the mower gets close. By default, the at least two doors may remain unlocked, yet closed, thereby providing a cost-effective solution for customers who do not have to worry about pets. An add-on module may be provided that may add a locking mechanism and triggering mechanism, thereby providing end users with the ability to lock the automated gate completely.

The present invention provides a multi-directional opening flap pet door, relating to the technical field of pet bearing devices, which comprises: a supporting door frame, a bearing door frame, a locking seat and a blocking door panel. When a locking column slides into a bidirectional locking hole, the blocking door panel is locked bidirectionally, and when the locking column slides into an entrance-exit sliding hole, the blocking door panel is open bidirectionally. It solves the problem that most of the pet doors currently rotate in one direction, and the pet door needs to be adjusted manually, which limits the applicability of pet boxes or pet cages for pet bearing.

A magnetic screen door includes a solid section in a screen to protect the screen from damage as users pass through the screen. In some embodiments, the apparatus includes a first and second panel each comprising a flexible mesh section, an inside lateral edge and an outside lateral edge. A magnetic element may be coupled to the inside lateral edges. One or both panels may include a solid inset. The apparatus also comprises a second panel. In an illustrative use, as an animal presses on the solid inset, the first and second panels separate to allow the animal through. The flexible mesh section is protected from damage since the animal makes contact with the solid inset instead of the more fragile mesh section.
