Definitions

  • the handrail which is the subject of these patents is intended for an accelerated moving sidewalk and is made up of handles connected together in pairs by a flexible link.
  • Each handle must be synchronous with the corresponding point of the movable floor, therefore the handles must deviate in the acceleration zones, approach in the deceleration zones and remain equidistant in the zones at constant speed.
  • This is achieved by mounting each handle on a small cart, two successive carriages being connected by a flexible flexible connecting element in one direction to ensure support if necessary between two handles; the flexible connecting element folds substantially at a right angle to the right of the handle by a pulley and is anchored to a tensioning trolley or trolley, the path of which can approach or deviate from that of the trolley carrying the handle, which ensures speed variation.
  • the flexible connecting element is constituted by a chain filled with blocks whose complex shape is determined so that the connecting element working in a bent beam on simple supports, that is to say subjected to a bending moment and with a sharp force, does not deform under a load; in fact, between two handrail handles, the flexible connecting element itself serves as a handrail, in the event of a stampede, for example.
  • the main drawback of this system is its complexity, which results in a relatively high cost.
  • the flexible connecting element is constituted by a continuous flexible link with a constant section, such as a belt, cable or set of belts or cables whose characteristic is to offer resistance to effort. cutting edge that the chains do not have, associated with compression blocks of simple shape fitting into each other.
  • a handrail element, connecting two handles, is constituted by a flexible link stretched between two attachment points and passing over two return pulleys spaced from one another, which form with the two attachment points a quadrilateral deformable as a function of transport speed, said link equipped of a series of adjacent blocks each comprising a lower face for fixing to the link, an upper hand support face and two front faces, respectively front and rear, perpendicular to the direction of the link, the front faces of a block being in contact over their entire height with the corresponding front faces of the adjacent blocks in a straight part of the tensioned link between the two pulleys and being able to deviate angularly in two convex parts of the rotating link on the pulleys, the two front faces, respectively front and rear of each block, having angular profiles deduced from each other by translation parallel to the direction of the link, each front face of a block comprising at least one boss and each rear face comprising at least one recess profile combined with that of the boss, so that, in the
  • the flexible link is constituted by a toothed belt.
  • Figure 1 shows in longitudinal section such a belt capable of being folded only downwards with a small radius in a certain area, but also upwards, with a much larger radius, in another area.
  • FIG. 1 shows another embodiment.
  • Figures 3 and 4 show the use of such a handrail in an accelerated moving sidewalk.
  • the handrail consists of a toothed belt 10 to which blocks 11 are fixed, the shape of which allows reciprocal nesting between two adjoining blocks, thanks to a boss 12 which comes to be embedded in a recess 13.
  • the fixing of a block on the back of the belt is carried out either by gluing 14, as for blocks 11a, 11b, or by bolting 16 on an insert 15, as for blocks 11c, 11d, this fixing always taking place at right of a tooth, location of maximum rigidity of the belt whose bending takes place mainly in the hollows between teeth.
  • the thickness of a block at any point, measured parallel to the back of the belt, is constant and equal to the pitch of the teeth.
  • any load on the handrail which works like a beam between simple supports, introduces a bending moment and a shearing force.
  • the longitudinal compression due to the moment is taken by the heads of the blocks, the tension by the belt; the shear force is transmitted from one block to another by the boss-recess pair and the resulting shear on contact belt block is taken up by gluing 14 or bolting 16.
  • the blocks 11 In zone 6, to allow the handrail to bend upward, the blocks 11 have a thickness which is very slightly decreasing regularly from the bottom up, the fixing of the blocks being identical to that of the other zones.
  • each block 17 comprises on each face perpendicular to the axis of the toothed belt 10 on the one hand a boss 18 and a recess 19, on the other hand and opposite the previous ones, a recess 20 and a boss 21.
  • the operation of this device is similar to the previous one. Different forms could be retained without departing from the scope of the invention.
  • FIGS 3 and 4 show the use of such a handrail in an accelerated moving sidewalk.
  • a handrail element 23 connects two handrail handles 24a, 24b, passing through the return gears 7a, 7b, and are anchored to speed variation trolleys 25a, 25b.
  • the handles 24a, 24b are provided with rollers carried by the axes 26a, 26b of the pinions 7a, 7b.
  • the axles 9a, 9b of the carriages 8a, 8b are provided with similar rollers and all these rollers move between two rails 27 and 28.
  • the speed variation trolleys 25a, 25b to which the ends of the belts are anchored, are held by a rail 30 at a variable distance D from the rails 27 and 28, which makes it possible to vary the spacing of the handles and, consequently, their speed, the flow rate, in number of handles per second being constant.
  • this same assembly is in an area where the handrail passes from a horizontal section to a ramped section.
  • the curvature is taken in zone 6, the radius r of which is obviously much shorter than the connecting radius R, the low speed zones 4 and 5 remaining rectilinear.

  1. Fördereinrichtungselement mit veränderlicher Länge, insbesondere anwendbar bei einem Geländergurt für eine Personentransportvorrichtung mit veränderlicher Geschwindigkeit, bestehend aus einem flexiblen zwischen zwei Befestigungspunkte gespanntes Verbindungsglied (10), das über zwei im Abstand angeordnete Umlenkrollen (7) läuft, die mit den beiden Befestigungspunkte ein entsprechend der Fördergeschwindigkeit verformbares Viereck bilden, wobei dieses Verbindungsglied (10) eine Reihe benachbarte Blöcke (11) aufweist, die je eine untere Befestigungsfläche auf dem Verbindungsglied (10), eine obere Abstützungsfläche für die Hand und zwei, je eine vordere bzw. eine hintere, senkrecht zur Richtung des Verbindungsgliedes angeordnete Frontflächen, umfassen, und wobei die Block-Frontflächen über ihre gesamten Höhe mit den ensprechenden Fronflächen der benachbarten Blöcke in einem geraden Teil des zwischen den beiden Umlenkrollen (7) gespannten Verbindungsgliedes (10) in Kontakt sind und winkelmässig in zwei über die Umlenkrollen umlaufende konvexe Teile des Verbindungsgliedes ausscheren können, dadurch gekennzeichnet, dass die beiden, je eine vordere bzw. eine hintere, Frontflächen von jedem Block (11) eckige Profile aufweisen, die sich voneinander durch eine zur Richtung des Verbindungsgliedes Parallelverschiebung ableiten, wobei jede vordere Blockfläche mindestens ein Vorsprung (12) und jede hintere Fläche mindestens eine Aussparung (13) mit einem dem Profil des Vorsprungs zugeordneten Profil aufweisen, sodass in dem geraden Teil des Verbindungsgliedes zwischen den beiden Umlenkrollen sich jeder Vorsprung (12) einer Vorderfläche eines Blockes (11) in eine konjugierte Aussparung (13) der zugewandten Hinterfläche des benachbarten Blockes eingreift und somit eine Zapfen- Nutverbindung bildet, die den auf das Verbindungsglied beaufschlagten Scherkräften standhalten kann, wobei die Vorsprünge sich von den Aussparungen in den konvexen Teilen des Verbindungsgliedes entfernen.
