The height raising member body characteristically includes: a base part connectable to the frame; and a supporting part capable of supporting the motor at a position upward away from the base, the motor being configured to drive the pulley via a belt.

An elevator car door apparatus includes a door frame, a door motor, a motor pulley, a reduction pulley, a first driving pulley, a second driving pulley, a reduction belt, and a driving belt. The door motor, the reduction pulley, and the first driving pulley are supported on the door frame by means of a unit supporting member. The unit supporting member includes a flat plate portion that is placed on a frame vertical surface of the door frame. The reduction pulley and the first driving pulley are rotatable around a fixed shaft that is fixed so as to be perpendicular to the flat plate portion.

Some examples provide a fire-rated elevator door frame assembly with a flush transom. The transom includes a transom assembly. A fire-rated partition sits behind the transom on the hoistway side of the elevator doors. Architectural cladding can be applied to the front of the transom and to the front of the elevator doors giving the appearance that the flush transom extends high above the elevator doors.

The invention relates to a method for condition monitoring of a rope of a hoisting apparatus, and to an arrangement for condition monitoring of a rope of a hoisting apparatus, preferably of an elevator for transporting passengers and/or goods. The arrangement for condition monitoring of a rope of a hoisting apparatus according to the present invention, in which rope comprises one or more conductive load bearing member for bearing the load exerted on the rope in longitudinal direction and extending parallel to each other and to the longitudinal direction of the rope, comprises an at least one eddy current testing probe, placed near said rope for generating an alternating magnetic field, said alternating magnetic field causing eddy currents in said rope, and for detecting a secondary magnetic field being generated by said eddy currents in said rope as eddy current detection data, and an on-line monitoring unit receiving and utilizing said eddy current detection data for on-line condition monitoring of said rope.

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 door safety system (3) for a door (2), having a safety component (10) arranged on a movable door element (4, 4a, 4b) of the door (2) and a supply component (11) arranged on a stationary door frame (5) of the door (2) for supplying energy to the safety component (10). The safety component (10) has an electric energy store (12) which is designed to autonomously supply electric energy to the safety component (10) when the door (2) is open, and the safety component (10) and the supply component (11) are designed to electrically charge the electric energy store (12) of the safety component (10) when the door (2) is closed.

A hoistway landing door locking system includes an elevator shaft and an elevator car disposed within the elevator shaft and moveable therein between a plurality of access openings located at a plurality of levels of the elevator shaft. Also included is a mechanical locking assembly disposed proximate at least one of the access openings, the mechanical locking assembly operable to switch the access opening between a locked condition and an unlocked condition. Further included is an electromagnetic locking assembly operable between an energized condition and an unenergized condition, wherein the energized condition is required to switch the mechanical locking assembly from the locked condition to the unlocked condition.

The present disclosure relates to a car door for a lift car having a guide mechanism and a door leaf. The guide mechanism comprises in this case a sliding shoe, which is connected to the door leaf of the car door. Furthermore, the guide mechanism comprises a receiving part which surrounds the sliding shoe on at least three sides. The sliding shoe has, in a sliding direction, an extent which corresponds to at least 30% of the extension of the door leaf in this direction.

There is disclosed an automatic door installation 100 configured to determine the presence of an obstacle 150 in one or more detection zones remote from a door opening, comprising: at least a first door 104 slidable in a door opening along a horizontal door axis from an open configuration to a closed configuration during a door closing operation; a plurality of transmitter-receiver pairs, each transmitter-receiver pair comprising: a transmitter 116 for transmitting a beam 140 and a receiver 118 for receiving a reflection of the beam, wherein one of the transmitter 116 and the receiver 118 is coupled to the first door so that, in use, the transmitter and receiver move closer together during the door closing operation; wherein the transmitter 116 defines a transmitter axis 120 corresponding to the optical axis of the beam; wherein the receiver 118 has a field of view 142 for receiving the beam, which is oriented around a receiver axis; and wherein the transmitter axis 120 and the receiver axis 122 are configured so that the beam and the field of view overlap to define a detection zone for the transmitter-receiver pair in at least one operational configuration of the door installation. At least one of the transmitter axis 120 and the receiver axis 122 is inclined with respect to the horizontal plane and the transmitter 116 is vertically spaced apart from the receiver 118.

A sill (1, 1′) for a lift door is manufactured with a method that includes the steps of providing at least one support element (2) and an upper profile (4) that defines at least a boundary surface (6) of a first groove longitudinal (8) for slidingly receiving a lift door. The support element (2) and the upper profile (4) are joined, placing a first demarcation profile (10, 10′) alongside the upper profile (4), so that a boundary surface (12) of the first demarcation profile delimits part of the first longitudinal groove (8). A sliding transversal cross-section of the first longitudinal groove (8) is adjusted by approaching/distancing the boundary surfaces (6, 12) and, having obtained a desired sliding transversal cross-section, constraining the mutual position of the first demarcation profile (10, 10′) and of the upper profile (4).
