Abstract:
In one aspect, a method of operating a movable barrier operator includes engaging a flexible driven member with a drive of the movable barrier operator. The method includes moving the flexible driven member in a first direction to move a movable barrier connected to the driven member and monitoring the position of the movable barrier. In response to the movable barrier reaching a given position, the driven member is moved in a second direction without moving the movable barrier to remove slack from the driven member. A movable barrier apparatus includes a movable barrier controller operatively coupled to a movable barrier operator. The movable barrier controller is configured to cause the movable barrier operator to reverse direction of a flexible driven member a distance after stopping movement of a movable barrier toward a limit position and without moving the movable barrier.

Abstract:
A self-closing device is for sliding doors of the type including at least one sliding leaf (2) which is hung from an upper profile (3). The device (1) includes a drive belt (10) configured to be joined to the sliding leaf (2); a closing pulley (20), provided with an elastic device (30), which is arranged on a first rotation axis (4) integral to the upper profile (3) and which engages with a first end (11) of the drive belt (10); and a brake pulley (40), provided with a stop (50), which is arranged on a second rotation axis (5) integral to the upper profile (3) and which engages with a second end (12) of the drive belt (10) opposite to the first end (11). The rotation movement of both pulleys (20, 40) is connected by the drive belt (10).

Abstract:
A coupling system of an elevator car door drive includes a traction device, at least one coupling unit coupled to the traction device, and an adapter element which has a first interlocking adjustment structure which, together with interlocking elements of the traction device, forms a first interlocking unit that secures a relative position of the adapter element with respect to the traction device, which relative position can be adjusted in defined interlocking adjustment positions. The coupling unit has a second interlocking unit which secures a relative position of the adapter element with respect to the coupling unit, which relative position can be adjusted in defined interlocking adjustment positions, wherein, in the second interlocking unit, the distance between directly adjacent interlocking adjustment positions is smaller than the distance between directly adjacent interlocking adjustment positions of the first interlocking unit.

Abstract:
Provided is a platform door device which makes it possible to reduce the length of time for a replacement operation when a panel-shaped portion of a door is damaged. The platform door device comprises a door, and a driving mechanism for moving the door forwardly and backwardly to close and open a gate on a platform. The driving mechanism includes a motor, a rotation body adapted to be rotated by the motor, and a driven body adapted to be driven according to the rotation of the rotation body so as to move the door, and the door has a panel-shaped main body, and a base segment detachably joined to the main body and attached to the driven body.
Abstract:
An apparatus and method of directionally controlling a movable partition includes providing at least one roller assembly and a steering actuator, coupled therewith, to a portion of the partition. A controller may be used to control the steering actuator and thereby select, or change, the orientation of the roller assembly with respect to the partition. In one embodiment, one or more sensors may be used to determine the vertical orientation of the partition including whether the partition, or a section thereof, is substantially plumb. If the partition is substantially out of plumb, for example, if a lower edge of the partition is laterally displaced relative to an upper edge of the partition, the controller and steering actuator may cause the at least one roller assembly to direct the partition, or section thereof, in a particular direction until the partition, or section thereof, becomes substantially plumb.
