  • Patent number: 11547210
    Abstract: A retraction device for movable furniture parts has a driver movable along a first guide path, which is movable between a retracted position and a parked position and is directly or indirectly pretensioned into the retracted position by an energy storage device. The driver can be coupled to an activator in order to move the movable furniture part into a closed position. A method uses the driver for opening and closing the movable furniture part and tensioning and releasing a retraction device.

  • Patent number: 8381895
    Abstract: A device (40, 50) for reducing noise levels in passenger conveyor systems (10) at least partially obstructs spacing (36) at the interface between two steps (24, 30) to allow for relative movement between one step and the next. A sound transmission reducing member (40, 50) at least partially obstructs a sound pathway that includes the spacing to reduce the transmission of noise through the spacing. The sound transmission reducing member in one example is a barrier that partially blocks the interface, while in another, it extends completely across the interface. Additionally, sound absorbing material (46) may be secured to the underside of the steps in order to further reduce sound transmission toward the passengers and individuals near the conveyer.

  • Patent number: 8016097
    Abstract: An escalator handrail drive arrangement includes a drive belt (26) mounted within a drive housing (35). Pressure rollers (30) are mounted in pairs and pivotally attached to the drive housing. The pressure rollers bias a handrail (22) against the drive belt. The pressure roller arrangements are mounted at each axial end. A spring (44) biases the pressure roller arrangements against the handrail, with the spring being centered along the axial length of the pressure rollers. This spring is preferably mounted within the drive housing such that no additional space is required outwardly of the drive and roller arrangement to accommodate the spring.

  • Patent number: 7770710
    Abstract: Method for compensating the length of a movable handrail (10) in a passenger conveyor (2) having a passenger transportation belt (4) defining at least one passenger transportation surface (8), the handrail (10) is traveling along a closed handrail path which extends through an exposed path (12) along the passenger transportation belt (4), around a turnaround means (14), through a return path (16) and around a further turnaround means (18), and which hand rail path defines a handrail plane which is substantially perpendicular to the passenger transportation surface, the method comprising the following steps: (i) turning the handrail (10) out of the handrail plane; (ii) directing the handrail (10) through a compensation means (38); and (iii) turning the handrail (10) back into the handrail plane.

  • Patent number: 7614490
    Abstract: A passenger conveyor handrail (30) has a gripping surface (32, 42, 52, 62, 72, 82) with a generally circular cross-section. Disclosed examples include a toothed driven surface (34, 44, 54, 64, 74, 84) that is adapted to be engaged by a toothed driving member (28) for propelling the handrail in a desired direction. Disclosed examples include having the generally circular cross-section extend along an entire length of the handrail (30) corresponding to the closed loop path followed by the handrail during operation of a corresponding passenger conveyor.

  • Patent number: 7562759
    Abstract: A passenger conveyor handrail (30) includes a plurality of teeth (36) that interact with a toothed driving member (42). In a disclosed example, a low friction material (60) is placed near an end of the teeth (36) on the handrail (30). The low friction material (60) facilitates the teeth sliding along a guidance (70) but does not interfere with a desired engagement between the teeth(36) and corresponding teeth (46) on the driving member (42).
