  • the above-mentioned balls are maintained in the corresponding blind holes in the tray the transfer element by a plate secured to the tray and including through holes respectively by the balls and a diameter smaller than the diameter of the balls and the balls of the comb plate are held in their holes corresponding blinds respectively with washers flat with central frustoconical holes.
  • the means of said bearings include rollers mounted at rotation transverse to the direction of travel pedestrians in corresponding accommodation approximately semi-cylindrical from the transfer element and comb plate protruding from this tray from this plate from so as to define the abovementioned bearing surfaces of the pedestrians.
  • the tray of the transfer element is on the one hand pivotally supported on a chassis support by support legs and other fixed to support frame by two tie rods located on each side of the tray outside the bearing surface thereof so as to allow a tilt angle adjustment to a position according to which the support surface of the plate is located in the plane common to the transport surfaces of the two transport elements.
  • the support feet of the tray the transfer element have their free ends housed respectively in inclined grooves transverse to the longitudinal direction of movement of pedestrians and carried out respectively in support parts integral with the chassis of the support, said transverse grooves allowing a transverse displacement by sliding of the element of transfer of a small quantity, of the order of a few millimeters, when the longitudinal grooves of one and / or the other of the transport elements strike the teeth of the comb plate.
  • Each tie member has a threaded end anchored in a tapped hole of a first axis transverse supported by a fork fixed to the plate of the transfer element and its other end threaded crossing with clearance a bore of a second axis transverse supported by a yoke integral with a support piece attached to the support frame, two nuts on either side of the second axis transverse joining the other threaded end of the pulling element in an axial clearance so to allow the element to pivot upwards transfer around the ends of the support legs when an object gets caught between the grooves longitudinal of one or other of the elements of transport and the teeth of the comb plate.
  • Each support piece of the clevis of the second axis transverse includes a transverse inclined groove of support of the end of a support bracket the transfer element.
  • the invention also provides a transporter, in particular for pedestrians, comprising an element of main conveyor belt type transport extended at each of its ends by an element transport able to function as an element acceleration or deceleration between the element of main transport and a fixed loading floor or unloading pedestrians, and which is characterized in that it includes a transfer device such as previously defined and arranged between the element acceleration or deceleration and the element of main transport.
  • the transporter of the invention will be described in application to pedestrian transport, but it is good understood that it can also apply to transport objects, such as goods, luggage, etc.
  • the conveyor belt shown in Figure 1, arranged between two fixed floors 1, 2, is of the type comprising a substantially flat strip 3 make it possible to carry pedestrians in the direction indicated by arrow F, i.e. in the direction longitudinal of the strip, and winding on two extreme drums 4, one of which is motor, arranged transversely to the direction of movement of pedestrians.
  • Conveyor belt 3 moves at a higher speed higher than the normal walking speed of a pedestrian.
  • the transporter also includes an acceleration element 5 arranged between the fixed entrance floor 1 and the entrance to the conveyor belt 3 defined relative to the meaning of displacement thereof and a deceleration element 6 disposed between the outlet of the conveyor belt 3 and the fixed exit floor 2.
  • the acceleration or deceleration element is known in itself and can be achieved as described in the document EP-A-0 509 861. More specifically, the element acceleration 5 or deceleration element 6 includes series of parallel nested rollers into each other so as to constitute a continuous transport area for pedestrians, and means for driving the rollers so that their speed gradually increases from one input roller from acceleration element 5 to a roller exit of this element or gradually decreases to from an element entry roller deceleration 6 to an output roller therefrom.
  • Figure 3 shows schematically the element acceleration 5 including the nested rollers 7 into each other and defining the surface of S1 pedestrian transport.
  • a transfer element 8 is arranged between the acceleration element 5 and the strip conveyor 3 or between conveyor belt 3 and the deceleration element 6.
  • each element of transfer 8 comprises a plate 9, the surface of which S2 pedestrian support is located substantially in a same plane common to the transport surface S1 of the acceleration 5 or deceleration 6 element and at the transport surface of the conveyor belt 3 and includes rolling means 10 allowing the virtually frictionless movement of pedestrians from the acceleration element 5 to the conveyor belt or from the conveyor belt 3 to the deceleration element 6.
  • the transfer element 8 comprises a comb plate 11, the teeth 12 of which respectively engage in longitudinal grooves 13 of the strip conveyor 3 defined between ribs 14 of this one.
  • the comb plate 11 is fixed on the plate 9 of the transfer element 8, for example by fixing screws 15 and its support surface S3 pedestrians located in the same plane as the support surface S2 of plate 9 and also consists of means bearing 16 allowing movement practically without friction of pedestrians of the comb plate 11 to the conveyor belt 3, or vice versa.
  • the rolling means of the plate 9 and of the comb plate 11 are constituted by balls 10, 16, the balls 10 being housed in corresponding blind holes 17 of the plate 9, while that the balls 16 are housed in blind holes correspondents 18 of the comb plate 11 as this is best illustrated in Figure 5.
  • the balls 10, 16 are held in their holes respective 17, 18 projecting from the plate 9 and the comb plate 11 so as to define the support surfaces S2 and S3 and rotate on themselves in these homes when pedestrians cross.
  • the balls 10 are held in their corresponding blind holes 17, made in a plate 9a added to the plate 9 of the element transfer 8 and fixed to it by screws 9b, by a plate 19 fixed to the plate 9a, for example by fixing screw 20, the plate 19 comprising holes 21 crossed respectively by the balls 10 and of a diameter less than the diameter thereof.
  • the balls 16 are held in the blind holes correspondents 18 of the comb plate 11 respectively by flat washers 22, each housed in a counterbore 23 machined in the plate 11, each washer 22 having its frustoconical central hole 22a in support on the ball 16.
  • the rolling means 10, 16 can be constituted by rollers mounted transversely to the direction longitudinal of the conveyor belt 3 in corresponding semi-cylindrical housings of plate 9 of transfer element 8 and from the comb plate 11 projecting from the plate 9 and plate 11 so as to define the pedestrian S2 and S3 bearing surfaces.
  • the plate 9 of the transfer element 8 is pivotally supported on a chassis support 24 by support legs 25 arranged symmetrically to the longitudinal axis XX 'of the strip 3 and whose free ends 25a are housed respectively in inclined grooves 26 support parts 27, 28 respectively of the chassis 24, the grooves 26 being aligned transversely to the longitudinal axis XX 'of the strip conveyor 3.
  • Two support pieces 27 are arranged symmetrically to the longitudinal axis XX 'of the band 3 and are fixed on a wing of a cross member 29 in L inverted by fixing screws 30, cross-member 29 being integral, for example by welding, with the chassis 24.
  • each transfer element 8 is bilaterally fixed to the support frame 24 by two tie-rod elements 31 arranged symmetrically at the axis XX 'outside the bearing surface S2 of the platform 9 so as to allow tilt adjustment of this tray to a position where the surface support S2 is located in the plane common to the surfaces transport respectively of the acceleration element 5 or deceleration 6 and the conveyor belt 3.
  • Each drawing element 31, parallel to the axis XX ′, has a threaded end part 31a anchored in a corresponding tapped hole 32a crossing a transverse axis 32 supported by a yoke 33 secured to an end part 9c of the plate 9 of the transfer element 8, which part 9c also includes a support tab 25, the lower free end of which is engaged in the groove 26 of the corresponding support piece 28 fixed to the cross-member 29 by fixing screws (not shown) .
  • the drawing element 31 has its other threaded end portion 31b passing through a hole 34a made through another transverse axis 34 supported by a yoke 35 of the support piece 28.
  • Two nuts 36, 37 are screwed onto the threaded part 31b of the pulling element 31 on either side of the transverse axis 34 so as to secure this threaded part to the axis 34.
  • the nut 37 is not fully tightened against the axis 34 and leaves a clearance j of approximately 2 millimeters so as to allow a slight pivoting of the transfer element 8 around the free ends of the support legs 25 in a direction tending to spread upwards, in view of the Figure 3, the comb plate 11 of the conveyor belt 3.
  • Such pivoting occurs when an object gets caught between the longitudinal grooves 13 of the conveyor belt 3 and the teeth 12 of the comb plate 11 and allowing the transport element 8 to actuate a contactor element intended to control the stopping of the drive roller 4 for driving the conveyor belt 3.
  • the transfer element 8 is held in a fixed position by the tie-rod elements 31 which each comprise a central nut 31c making it possible to precisely adjust the position of the bearing surfaces S2 and S3 of the transfer element 8 relative to the transport surfaces of the acceleration element 5 or deceleration element 6 and of the conveyor belt 3.
  • FIG. 3 shows that the bearing surfaces S2, S3 of each transfer element 8 can be offset below the transport surface of the conveyor belt 3 to a value of approximately 5 millimeters without an imbalance being inflicted on pedestrians crossing the very small transition zone between the end of the comb plate 11 and the conveyor belt 3.
  • each transverse axis 34 is mounted in two oblong holes (not shown) of the yoke 35 extending parallel to the axis XX 'of the conveyor belt 3.
  • the above described transfer device the invention is of an extremely simple structure, does not requires no level change in the area of transition between an acceleration element or a deceleration element and the conveyor belt and allows reversibility of operation of the conveyor belt, i.e. the displacement of the conveyor belt can be done in one direction or in the other.
  • the transfer device the invention can be used in conveyors called "moving walkways", where the conveyor belt is made up of elements linked to each other.
  • the transfer device of the invention can be installed between two aligned conveyor belts in extension of one another or offset one by relation to each other by forming an angle in which would be arranged the transfer device, the latter comprising two end plates forming a comb, the teeth are engaged in the grooves longitudinal respectively of the two bands conveyors.
