An automatic built-in closing apparatus includes at least one common pivoting shaft that is driven by a unique motor, intermediate gear wheels and a clutch coupled to control doors of a series of lockable compartments pertaining to a same block of an electronic locker unit and a set of freewheels and overload clutch which is mounted on the common pivoting shaft as a hinge for each door of the series of lockable compartments.

A product display unit serves the purpose of the accommodation and presentation of products, which can include foodstuffs to be cooled. The product display unit includes a receiving space for products, a plurality of doors, which are mounted in a pivoting manner around a swivel axis between an open position and a closed position. At least a part of the doors is also mounted in a displaceable manner along a guide assembly.

An enclosure for waste material includes a movable front section and a stationary rear section. Movable intermediate sections may also be provided between the front and rear sections. Each section is formed by a frame with a rigid skin, with adjacent sections being sized so as to telescope with respect to one another. The front and any intermediate sections are rollable between an extended position to cover the waste material and a retracted position uncovering the waste material. A reversible electric motor may be actuated remotely or by a switch to open and close the enclosure. The enclosure protects the contents from the weather, from birds and other animals, and from unauthorized human access.

A telescoping aircraft door is disclosed having first and second panels that slide relative to one another to extend and retract as the door closes and opens, respectively. The first panel is hinged to the door frame in a traditional manner, and the second panel is fixed to the door frame by a linkage that limits the arc of the second panel. By selecting the location and length of the linkage, the relative movement of the two panels can be predictably controlled to reduce the depth of the door when closed and the length of the door when opened.

An economical bi-parting door assembly for an aisle between two rows of data center IT racks is disclosed which is easy to assemble, has no floor track or leveling requirements, and an overhead suspension and drive assembly for the left and right door assemblies. Guide ribs and channels can be provided for the door leaves at the lower portions of the leaves and mating features are placed on the leading faces of the leaves. Some features are designed to work specifically with a containment system frame for server cabinets.

An access control system controls synchronous or coordinated motion of two or more gates using a controller that calculates travel time for each gate and that adjusts the speed of the motors driving the gates to so allow the gates to reach the open and/or closed position at the same time, regardless of the length of the individual travel paths of the gate.

An electric vehicle having a charging flap module. The vehicle includes a body having a body interior, which has a body element having an outer skin. The body element has a charging port, in which the charging flap module is arranged with a charging interface. The charging flap module is configured to be fixed to the body and with a charging flap. The charging flap is configured to be movable between an open position and a closed position for opening and closing the charging port. The charging flap comprises at least two movable flap parts. The flap parts are pivotable in a storage space of the body interior receiving the charging interface.
