The second plurality of knuckles is interdigitated with the first plurality of knuckles and pivotally coupled to the first plurality of knuckles. Each knuckle is a separate piece.

A flexible coupling and an actuator for shaft-driven structures are provided. The flexible coupling includes a first half coupling, a second half coupling and a flexible member connected between the first half coupling and the second half coupling. One end face of the flexible member is provided with at least two connection portions extending along the axial direction. The first half coupling includes a support portion configured to support the radially inner surface of each connection portion and first transmission portions configured to fill circumferential gaps between the connection portions. The second half coupling includes second transmission portions equal in number to the connection portions. The second transmission portions cover radially outer side surfaces of the connection portions in a one-to-one manner. The flexible coupling can prevent the flexible member from being disengaged from between the two half couplings during operation. The actuator includes the preceding flexible coupling.

A door drive for arrangement on or in connection with a door system, wherein at least one leaf element of the door system is movable, including a motor unit with a housing, in which a stator is stationarily received, and wherein a rotor is arranged so as to be rotationally-movable in the housing and includes an output shaft, wherein the output shaft can be brought into operative connection in a driving manner with the leaf element. The motor unit has the basic shape of a cuboid, which is formed at least by two housing halves connected to each other.

A method of arranging an overhead sectional door (SD) in a doorframe (10; 20) that defines a door opening, the overhead sectional door (SD) comprising a plurality of door panel sections (100; 200; 300; 400; 500). The method disclosed herein involves: a) fitting a first door panel section (100) in the doorframe (10; 20), b) fitting a second door panel section (200) in the doorframe (10; 20), and c) actuating an electric motor (M) to cause the first door panel section (100) to push the section door panel section (200) a distance in an upward direction. The method further involves: d) securing the second door panel section (200) with respect to the doorframe (10; 20), e) causing said at least one electric motor (M) to move the first door panel section (100) a distance in a downward direction, thereby leaving a space (60) between the secured door panel section and the first door panel section (100), f) fitting a next door panel section (300; 400; 500) in the space (60), and g) causing said at least one electric motor (M) to move the first door panel section (100) a distance in an upward direction. Further, the method involves: h) unsecuring the secured door panel section (200; 300; 400; 500) with respect to the doorframe (10; 20), causing said at least one electric motor (M) to move the first door panel section (100) a further distance in an upward direction, engaging the top edge of the next door panel section (300; 400; 500) with the bottom edge of the previously secured door panel section (200; 300; 400; 500), and securing the next door panel section (300; 400; 500) with respect to the doorframe (10; 20). The method also involves repeating steps e) to h) for each next door panel section (300; 400; 500) until at least all but a last door panel section of the overhead sectional door (SD) have been arranged.

The invention relates to an elevator landing door assembly and a method for installing an elevator landing door. The landing door assembly comprises at least a landing door unit to be assembled to a landing door base opening having an upper edge, two side edges and a lower edge, which landing door unit comprises at least a top track and one or more door panels suspended by the top track through one or more supporting elements, and a door sill. The assembly comprises fixing elements in the landing door base opening equipped with receiving parts for fastening the landing door unit.

A low-bulkiness hinge for closing a closing element anchored to a stationary support structure, such as a wall, a frame or a floor includes a hinge body which includes a longitudinal operating chamber defining a first axis, a pivot coupled to the hinge body to rotate around a second axis between the opening and closing positions of the closing element, and a slider slidable in the operating chamber along the first axis. The operating chamber has a first seat for the pivot and a second seat for the sliding of the slider, which includes a shaft and an operative head that are mutually coupled. The hinge body has a first opening for inserting, perpendicularly to the first axis, the operative head into the second seat and a second through opening for inserting, coaxially to the first axis, the shaft into the housing. The hinge further has the shaft and the operative head fixed to one another after insertion in the second seat (so as to form a unitary assembly integrally slidable along the first axis.

Disclosed herein is a continuous hinge.

The present subject matter discloses an integrated hinge structure for plastic boards. The integrated hinge structure has a simplified design that is screw-free and convenient to assemble. It also has a relatively lower manufacturing cost. The integrated hinge structure can comprise a first board and a second board that can be coupled to each other. Furthermore, the first board is divided into a first turning portion and a second turning portion by an embedded groove hinge. The second turning portion is further detachably connected to the second board. The integrated hinge structure further comprises fixation features to render the constructed assembly stable and durable.
