摘要： An escalator is provided with a curved path of travel from its entry to its exit landings. The path of travel of the escalator steps as seen in plan is a curve having a fixed center and a constant radius from landing to landing. In elevation, each landing portion will be disposed in vertically spaced horizontal planes, and there will be a medial constant slope ascending or descending portion. Interconnecting each landing portion with the constant slope portion will be entry and exit transitional curved portions of varying slope as seen in the elevational view. To enable the steps to traverse the curved path successfully, the effective length of the outer of the step chains is varied at different points along the path of travel of the escalator.

摘要： A moving handrail on an escalator or the like is driven by pairs of rollers which form a nip through which the handrail moves. The rollers are eccentrically mounted so as to automatically tighten the nip in response to resistance to movement of the handrail. The roller or rollers which contact the underside of the handrail are rotatably driven by power sprockets, while the roller or rollers contacting the outer or exposed surface of the handrail are idler rollers which are not rotated by the power sprockets so as to lessen scuffing of the exposed surface of the handrail by the rollers.

摘要： A pitless elevator system removes a car buffer and machine, and other components where so equipped from under the elevator car such that the elevator car can be operated to a clearance between it and a floor of a hoistway of about three inches. The machine may be mounted on board the car or may be located elsewhere and the car buffer located in normal side clearance space. The system further provides a retractable toe guard to allow the car to bottom at the indicated distance from the floor. The system facilitates retrofit applications of elevators without the prior art drawback of digging a pit.

摘要： The curved escalator has inner and outer step chains that are entrained on inner and outer sprockets which have different diameters, the outer sprocket having a larger diameter than the inner sprocket. The steps of the escalator reverse their direction of movement at the sprockets and pass from the passenger bearing run to a return run beneath the passenger bearing run. One of the sprocket sets is the power or driving set and the other is an idler set, which will be spring biased to maintain chain tension. In order to reverse the steps, they must tip or dip sideways because of the different sized sprockets. The dip zone of the roller tracks has an S curve to minimize noise and allow location of the track splice on the tensioned end of the escalator to be placed over the axis of rotation of the tensioned sprockets.

摘要： An escalator combplate is equipped with a stop switch that will interrupt the power to the escalator when objects trapped between the stop treads and combplate impose a predetermined lifting force on the combplate. The necessary lifting force is determined by code requirements, and the combplate is subjected to an upward spring force which equals the code-dictated lifting force. While the combplate is being lifted by the spring force, the stop switch or switches are set so that they will actuate at the calibrated position of the combplate. The spring force is then removed to allow the combplate to settle back to its normal operating position.

摘要： A power switch assembly is operably connected to the combplate of an escalator for selectively shutting off the escalator in the event of entrapment of some object between the steps and combplate. When an object becomes wedged between the steps and combplate, the latter will be lifted or pushed upwardly away from the steps. The upward movement of the combplate operates a power interruption switch to stop further movement of the steps and handrail. The combplate is supported on the truss by spring assemblies which serve to effectively lower the weight of the combplate so that upward movement of the latter is more readily accomplished. The assembly can be retrofitted onto older existing escalators with heavier combplates than are found in newer equipment.

摘要： The handrail drive has opposed rollers which are movable toward and away from each other due to their eccentric mountings. Two sets of such opposed rollers are used to drive the handrail. Each set of rollers is equipped with its own drive chain to increase the efficiency of each set of drive rollers with ultra high loads. The drive is particularly suited for moving high load escalator and moving walkway handrails.

摘要： The outer and inner side decks of a curved escalator are connected at its inner end to the balustrade, and includes a horizontal top panel which extends outwardly away from the balustrade, and outer vertical curved in plan side panel which extends downwardly from the outer edge of the top panel. These deck panels are secured to inner support components of the deck. The corner of the deck where the top and side panels meet is covered with a plastic trim molding which covers the screws fastening the side panel to the underlying supports, and which snaps onto catches which are hidden on the underside of the top panel. An attractive corner is thus formed free of unsightly screws, bolts, or other fasteners.
