A door suspension device includes a driving-side member, a hanger, an elastic member, and a first adjustment bolt. The hanger is configured so as to be displaceable in an opening and closing direction in conjunction with the driving-side member and supports a door. The elastic member allows relative displacements of the driving-side member and the hanger by elastically deforming in accordance with a load between the driving-side member and the hanger. The first adjustment bolt is a member for adjusting an initial value of a load that acts between the driving-side member and the hanger. The first adjustment bolt includes a male screw section to be fixed to the driving-side member, and a head which is arranged so that an axial force acting on the first adjustment bolt is received by an edge of the hanger.

The invention relates to a product display unit (1), in particular in the form of a refrigerator, which serves the purpose of the accommodation and presentation of products to be cooled, preferably foodstuffs, whereas the product display unit (1) includes a receiving space (2) for products, and whereas the product display unit (1) includes a multiple number of doors (3; 4), which are mounted in a pivoting manner around a swivel axis between an open position and a closed position. In accordance with the invention, it is proposed that at least a part of the doors (3, 4) is also mounted in a displaceable manner along a guide assembly (5).

A display has at least one pair of revolving door panels hinged to a box frame by means of hinging means actuated by actuation means intended to permit the synchronous movement of the door panels of the pair of door panels.

A system for a vehicle includes a first closure panel of the vehicle operable between open and closed positions, a second closure panel of the vehicle operable between open and closed positions, at least one sensor that is coupled to the first closure panel and that detects precipitation, and a controller that prompts movement of the first closure panel from a first open position to a second open position based on the detected precipitation.

A domestic cooling appliance has a housing and at least one receiving space for receiving food and first and second doors for closing the receiving space in the front. A first door is pivotally arranged at the housing a second door is pivotally arranged at the housing. The two doors are adjacent one another for closing the at least one receiving space at the front. The two doors are coupled to each other by a moving device, by which, upon operation of one of the two doors, automatically a concurrent movement of equal type of the other door is achieved.

A motorized window blind includes a slotted motorized track member mounted to a vertical wall structure of a building and extending across the top of an opening in the wall. It also includes at least two panels mounted to the track and covering the wall opening while being in a position where the panels are parallel and coplanar with one another. The motorized track member has at least one motorized actuation system enabling one panel to move forward away from the opening thereby freeing the track for the second panel to laterally slide behind the first panel. The panels become stacked in a parallel superimposed position in relation with one another. In the stacked position, the panels cover a portion of one end of the opening while completely uncovering a potion at the other end of the opening.

An oven appliance includes a cabinet that defines a chamber. A pair of doors is rotatably mounted to provide selective access to the chamber of the cabinet. The pair of doors is connected with a linkage assembly such that the doors rotate open and closed simultaneously. The linkage assembly includes a spur gear that engages another gear of the linkage assembly. The spur gear can hinder unwanted rotation of the pair of doors or compress the pair of doors against a seal.

A door operating system or door opening and closing apparatus comprising at least one motive source, a linkage assembly and a door. Preferred door operating systems will include two linkage assemblies, two doors and two motive sources, one for each door. Each motive source is preferably attached to an interior facing surface of a frame of a structure and the door is pivotally attached to an exterior facing surface of the frame of a structure. Each linkage assembly operatively connects the respective motive source to the respective door. By having the motive source attached to the interior facing surface of the frame, doors of the operating system can preferably be opened the full width of the frame opening to maximize available vehicle clearance.

A gate opener for simultaneously operating a pair of opposed sliding gates. The gate opener includes a pair of identical pulley assemblies one each affixed to the ground adjacent to a either gate and oriented a hundred eighty degrees to each other. A first cable is affixed to a lateral edge of a first gate, passes through a series of pulleys and is affixed to a medial edge of a second gate. A second cable is affixed to a lateral edge of a second gate, passes through a series of pulleys and is affixed to a medial edge of the first gate.

Door operator systems are described herein that include the use of an adaptor. It should be understood that the adaptor may be utilized in order to operatively couple separate door operator assemblies together in a double door operator system. The adaptor may include control components (e.g., switches, buttons, toggles, levers, or the like) that are used to turn the door operator system on and off. While the adaptor may be used to operatively couple two separate door operator assemblies together to form a double door operator system, the adaptor may also be used within a single door operator system. Furthermore, with respect to double door operator systems, the system may also utilize a back plate assembly comprising two or more separate back plates (e.g., two or more back plate portions).
