摘要:
Dual path moving walkway of the type where pallets or treadplates circulate about the terminal ends has a swivel joint connecting the inner sides to enable the pallets to move in a horizontal plane or up an incline. The swivel joint consists of overlapping links mounted at the trailing edge of one pallet and the leading edge of the adjacent pallet and interconnected by vertical pivot pin which carries a ring located in an aperture in one of the links. The outer surface of the ring and the corresponding wall of the aperture are spherical to permit relative movement in a vertical plane between the ring and the link. Consequently, the adjacent pallets can pivot relative to each other in a horizontal plane and in a vertical plane.

A transportation system comprises a plurality of successive load carrying components, means for moving the components along a closed-loop path and means for controlling the speed of the components and their distance apart. The controlling means is operable by moving the components along the closed-loop path without rotation of the components traverse to the closed-loop path direction.

A cable drive system suitable for use with moving walkways wherein a plurality of serially connected platforms (10) travel in a circuitous path of travel that includes change-of-direction regions (18, 20) connected by constant speed zones is disclosed. The cable drive system of the invention is particularly suited for use with an accelerating and decelerating moving walkway wherein acceleration and deceleration zones are located at the beginning and end, respectively, of each constant speed zone. The cable drive system comprises a drive cable (60) positioned beneath the constant speed zones of the path of travel and releasable cable-coupling mechanisms (98) associated with and connected to the platforms (10). An actuating mechanism (94, 96 and 122, 124) actuates the cable-coupling mechanisms to grip the cable (60) at the beginning of the constant speed zones and release the cable at the end of the constant speed zones. In a preferred embodiment, the primary drive cable (60) described above is supplemented by an auxiliary cable drive mechanism that engages the platforms in the change-of-direction regions only. The latter, or low-speed, cable drive mechanism includes a cable (62) that travels around the periphery of the change-of-direction regions (18, 20), and concave grooves (142) formed in the platforms that frictionally engage the cable (62) in the change-of-direction regions.

A dual path moving walkway or pair of escalators or walkways is provided with two re-cycling handrail belts. (20,21). The handrail (20) on the outer balustrade of one path or escalator crosses between the pair of paths or escalators and on to the outer balustrade of the other by guides (D.I) which impart a twist to the belt and allows it to bend about its transverse axis. The inner belt (21) passes from one inner balustrade to the other via a horizontal pulley. Removable panels in the balustrades permit removal of the'handrail belts from their guides and then removal from the balustrades.

@ Disclosed is a transportation device comprised of a series of load carrying components (1) connected together so that the distance between the components vary thereby allowing the components to move in a closed loop path. Rotatingly driven endless screws are positioned along the closed loop path and are engaged by a projection associated with the component as a particular component moves along a screw. The thread pitch of the screws is arranged to control the distance between adjacent component and the speed of the components.

Transporteur sans fin à vitesses localement différentes. Le transporteur utilise un dispositif de dilatation-contraction, comprend une suite de fourches 13 guidées sur un trajet en boucle fermée dont une tronçon 16 coincide avec un tronçon du trajet des axes 2 d'un tapis sans fin, chaque fourche 13 étantapte à saisir un axe 2 et étant reliée à l'une des fourches voisines, par un dispositif de liaison réglant, suivant un programme pré-établi, l'écartement entre ces deux fourches en fonction de la position de la première fourche, de telle sorte que cet écartement diminue progessivement dans une première zone 17 du tronçon de coincidence et augmente progressivement dans une deuxième zone 34 dudit tronçon, située en aval de la première zone. L'invention s'applique notamment aux trottoirs roulants.
摘要:
A dual path moving walkway has recirculating pallets or treadplates which are releasably latched at their outer sides during movement in the passenger-carrying areas between the ends of the walkway. At the ends, the latches are released. The latch means has, on one pallet, a pair of pivotal arms (13) which carry a wheeled axle (15) and on the adjacent pallet a recess (8) to engage the axle (15). In the passenger-carrying area a transport rail (12) retains the axle (15) in said recess (8); at the end of the carrying area the rail (12) terminates and the axle (15) drops out of engagement, thus releasing the outer side of adjacent pallets.
