A vehicle tailgate with an integrated collapsible door comprises a tailgate having an outer wall, an inner wall and a cavity there between, a door section of the tailgate having an inboard wall and an outboard wall and being moveable between a closed position and an open position substantially within the envelope of the tailgate, the inboard wall and the outboard wall being connected by a linkage to permit relative movement there between, a first track to guide the motion of the inboard wall and a second track to guide the motion of the outboard wall, and a power drive unit to power the motion of the door section, such that in the closed position of the door section the inboard wall is flush with the inner wall of the tailgate and the outboard wall is flush with the outer wall of the tailgate, and in the open position of the door section at least a portion of the inboard wall and at least a portion of the outboard wall lie within the cavity between the outer wall and the inner wall of the tailgate.

The invention relates to a sliding security gate inside a pocket attached to an interior pre-hung hinged door. These pocket sliding security gates can be assembled inside any doorway opening of one's home for the protection of babies, toddlers, pets, and disabled elderly. On one hand, the Pre-Hung Hinged Door and Pocket Sliding Security Gate can be used as a dual functioned component that can be used in a normal setting to provide privacy; on the other hand, the Pre-Hung Hinged Door and Pocket Sliding Security Gate can be used as a half door that is assembled as a pocket sliding security gate to provide safety and security to the vulnerable population listed above. In addition, this pocket sliding security gate also has an alarm attached to the security gate so that when it opens, the alarm sounds to let the gatekeeper know that the security has been breached.

A refrigerator having a structure in which, when a first door or a second door is opened, a lamp installed at sidewalls of an opening in the first door emits light so that food stored in a door guard disposed in the opening can be illuminated. The refrigerator includes a main body having a storage compartment; a first door that is rotatably disposed in front of the main body and opens/closes the storage compartment, and has an opening formed therein, where at least one door guard is disposed in the opening; a second door that is rotatably disposed in front of the first door, opens/closes the opening, and is rotated in the same direction as the first door; and a lamp installed at the sidewalls of the opening.

This disclosure pertains to a pet door apparatus, and in particular, a pet door apparatus integrated within sliding glass door frames of apartment units and other enclosed building structures. A pet door apparatus consistent with the present disclosure comprises a plurality of panels which features a flap within one of the panels. The plurality of panels are coupled to each other by at least one attachment mechanism. The coupling between the first panel and the second panel and the coupling between the second panel and the third panel forms an assembled unit. The point of coupling between at least two of the panels is adjustable to extend the length of the assembled unit. An end of one of the panels is fitted within the first track of the slidable door frame. An end of one of the other panels is fitted within the second track of the slidable door frame.

A refrigerator with an enhanced door includes a main body including a storeroom, first and second doors pivotally coupled to the main body to open or close the storeroom and a pivot bar pivotally installed at the first door. The pivot bar is movable between a first position between the first and second doors and a second position pivoted toward the first door to prevent cold air leaks from the storeroom. A locking device separably locks the pivot bar to the first door when the pivot bar is in the second position.

Disclosed is a refrigerator, more particularly a refrigerator including dual doors that are convenient to use. The refrigerator includes a main body having a storage space therein, a first door hinged to the main body for opening and closing the storage space, a door frame provided at the first door, a second door hinged to the first door, the second door having a side wall, at least a portion of which is inserted into the door frame, and a catching part provided in the side wall, and a locking device for selectively allowing the second door to be turned with respect to the first door, wherein the locking device includes a moving member, the displacement of which is changed depending on the open or closed state of the first door, and a catching member, the displacement of which is changed depending on the displacement of the moving member, whereby the protruding length of the catching member from the door frame is changed, the catching member being selectively caught in the catching part.

A refrigerator with an enhanced door includes a main body including a storeroom, first and second doors pivotally coupled to the main body to open or close the storeroom and a pivot bar pivotally installed at the first door. The pivot bar is movable between a first position between the first and second doors and a second position pivoted toward the first door to prevent cold air leaks from the storeroom. A locking device separably locks the pivot bar to the first door when the pivot bar is in the second position.

The present invention relates to a removable pet door. The removable pet door comprising a lower wall section hingedly connected to an upper wall section. The present removable pet door addresses or ameliorates some of the issues encountered by presently available pet doors.

A building wall module for partitioning a first region from a second region has a frame structure with inner and outer wall panels and lateral fastening devices for connecting the building wall module to a building. In addition, a sliding door system and a secondary door system are integrated in the frame structure, wherein the secondary door system is arranged separated from the sliding door system and can be controlled separately from the control device of the sliding door system. An electrical interface device connects the building wall module to a building system of a building.
