Abstract:
A roller for use in a roller guide for sliding elevator doors may include a resilient element for effecting quieter elevator operation. The resilient element may form a roller body with a bowl shaped annular casing of sheet steel to run along a carrier section including a preferably greased rail running surface. The roller body may be dimensioned such that the spring effect of the resilient element is stressed only within the elastic range or limit of the sheet steel. To obtain optimum spring effect, a radius of the rail running surface may be slightly greater than a radius of the roller body. Also, the roller body may include an open side.
Abstract:
Disclosed is a method for producing a transparent object that attracts a viewer's attention. At least some of the object surface facing the viewer is illuminated by means of an illumination source that irradiates a bottom surface of the object, said bottom surface facing away from the viewer. The disclosed method is characterized in that the object is provided with a surface that is reflective in incident light.
Abstract:
A door with a sliding door leaf has guides that are arranged in the region of an edge of the door leaf. The guides include a belt so aligned that it extends by the belt length thereof longitudinally of the guide surface for the door leaf in the direction of sliding of the door leaf. When the door leaf is sliding, the belt runs with the door leaf in such a manner that a portion of the belt bears against the guide surface when the door leaf is open, closed and sliding and thereby guides the door leaf.
Abstract:
A door system includes a reel, a door interconnect at a first end to the reel for winding and unwinding thereupon and one or more guide channels. The reel is rotatably mounted on a lever which is pivotally mounted to a pivot axis. Thus, the reel can pivot about the pivot axis to ensure that, during operation, a point at which an outer layer of the door engages/disengages with the penultimate door layer remains in the same general location with respect to the guide channels and accordingly, an angle (if any) at which the door enters the guide channels remains constant throughout operation of the door system.
Abstract:
An elevator having a car and a suspension member or respectively hoisting member for carrying an operating weight. Furthermore, a power transmission is intended for moving the suspension member and the hoisting member over at least one moving surface of the power transmission. The power transmission and the suspension member or respectively hoisting member are rope-shaped and/or belt-shaped. Also, the power transmission and the suspension member or respectively hoisting member are physically separated from each other. The power transmission and the suspension member or respectively hoisting member are stretched against at least one supporting body.
