The invention relates to a refinement of a spindle drive (1), and to a louvered window or a louvered shutter having a spindle drive for moving louver elements such that applied return forces and return torques can be absorbed better, and in particular without placing a load on the drive motor. For this purpose, the spindle drive (1) has a specially designed return stop mechanism (6) arranged between a drive shaft of a drive motor (3) and a threaded spindle (4).

The present invention discloses a sliding rail type low-obstacle linkage shower room and an installation method thereof. The shower room includes an upper rail and a lower rail, a fixed glass, a primary shower glass and a secondary shower glass. The lower rail is correspondingly provided at the secondary shower glass. A sliding block unit is installed on the secondary shower glass. The sliding block unit includes a fixed portion, a sliding groove and a guidance sliding portion. The fixed portion is provided correspondingly to the secondary shower glass. The sliding groove is used for receiving the primary shower glass to form a linkage. The guidance sliding portion is glidingly engaged with the lower rail. The linkage shower room has a simple structure which can be easily manufactured.

There is described a door assembly for a bathing enclosure, comprising: a frame; a rotatable panel rotatably securable to a wall; and a slidable panel slidably secured to the frame, wherein a sliding motion of the slidable panel triggers a rotation of the rotatable panel, wherein the door assembly is movable between an open position and a closed position, wherein when the door assembly is in the closed position, the rotatable and slidable panels are adjacent to one another and are unparallel and wherein when the door assembly is in the open position, the rotatable and slidable panels overlap one another and are parallel together.

A twin louver bank window assembly for efficient thermal control, the assembly including an assembly surround frame including a head member, a sill member and at least a pair of opposed side channel members and a pair of louver banks mounted relative to the assembly surround frame, each louver bank including a number of louvers, one louver bank located towards an outer side of the assembly surround frame and one louver bank located toward an inner side of the assembly surround frame.

A window control apparatus and a window control method thereof which can prevent erroneous operation of a window at the time of simultaneously operating a plurality of windows, may include a sensing unit of sensing a position of a window, a driving unit of driving the window, and a controller configured to control the driving unit to perform a window up operation upon reception of a window up operation command, to check whether a current position of the window has reached the upper end portion of a window frame, to control the driving unit to reversely drive the window when the window has not reached the upper end portion of the window frame, to control the driving unit to stop the window up operation and perform a window restraining operation if other windows stop when the window has reached the upper end portion.

A covering for an architectural opening has a dual cord operating system. The covering may include a head rail, blind panels depending from the head rail, and an operating system. The operating system may include a housing connected to the head rail, a first drive assembly rotatably mounted within the housing and operable to move the blind panels between an extended configuration and a retracted configuration, and a second drive assembly rotatably mounted within the housing and operable to move the blind panels between a closed configuration and an open configuration.

A power supplying facility includes: a power supply device installed in a building that has a power supply space for supplying power to an electric vehicle having a battery, and supplying power wirelessly to the battery of the electric vehicle parked in the power supply space by means of an automatic parking function, and a building air conditioner communicatively connected to the power supply device, and conditioning air inside of the building based on an operating state of the power supply device.

A bidirectional door opening module includes a vehicle body panel located between a first door configured to be rotated to open one end of a vehicle and a second door configured to be rotated to open a remaining end of the vehicle, and a drive unit coupled to the vehicle body panel and configured to apply opening force to the first door and the second door, wherein the drive unit includes a driver configured to apply driving force so as to open the first door or the second door, rail units configured to receive the driving force of the driver and then to apply opening force to the first door or the second door, and hinge units coupled to the rail units and configured to perform rotary opening of the first door or the second door.
