Definitions

  • the present invention relates to a system and method for driving mobile carriages on a rail, as well as an application to an installation and method for storing and placing the seats of a room with multiple events.
  • German patent No 1,015,210 has the particular disadvantage of also requiring a large annex storage volume if one wants to remove all the seats.
  • Patent DE-1,254,852 is also known, in which an installation for storing and installing rows of seats comprising at least two carriages connected by a connecting element is described. Such an installation has drawbacks in use, especially in terms of spectator safety.
  • the present invention therefore aims to overcome the drawbacks set out above by proposing a storage installation and installation of seats from a low-volume storage area to a use area and vice versa by implementing a system and an automatic process for driving the carriages.
  • Another objective is to automatically allow the removal of the seats from a floor with several inclinations to transform it into a floor of a single inclination devoid of seats and vice versa.
  • Yet another objective of the present invention is to allow the partial establishment of the rows of seats according to the intended use of the room.
  • the invention firstly relates to a system for driving movable carriages on a rail, ensuring the passage from a first zone in which the carriages are brought closer to a second zone in which the carriages are separated and conversely, comprising at least two carriages connected by a flexible or foldable connecting element (DE-A-1254852).
  • the system is distinguished in that said connecting element has a predetermined clearance (D) relative to the carriage in the direction of the rail, and in that it further comprises carriages for the carriages via a retractable storage member, arranged on a drive chain at predetermined intervals between a length L and (LD), L being the length maximum pitch between two consecutive carriages, said chain being attached to the last carriage and extending parallel to the rail over the entire second zone and partly over the first zone.
  • D predetermined clearance
  • said movement is achieved by a longitudinal clearance of at least one articulation of the connecting element on the carriage.
  • the retractable member of the carriages is an elongated member, articulated to the carriage, and is subjected to the return of a spring which tends to keep it in the projecting position and oriented towards the storage area, said member being retractable. upwards when the tabs pass in the direction of the storage area.
  • said connecting element is constituted by two blades connected to each other by at least one substantially central hinge.
  • the movement of the connecting element of said system is carried out on the upstream plate which further comprises an inclined face oriented towards the storage area and intended to initiate the folding of the blades when a stop of the carriage comes against it at the start of the storage operation.
  • the floor comprises at its upper level above the rails, lateral grooves facing one another, in which a continuous covering element for the rails can slide when the seats are stored.
  • said carriage drive system further drives the continuous covering element, the latter being fixed to the last carriage.
  • the present invention also relates to a method implementing the system for storing and placing trolleys:
  • This method comprises the deployment a first phase in which the upstream carriage driven by the chain pulls the downstream carriage from the off-chain storage area to the drive chain via the tensioned connecting element; in a second phase, said downstream carriage is towed individually by a chain driving cleat.
  • the upstream carriage in a first phase, is driven back to the downstream carriage to compress or fold the connecting element; finally, the row of downstream seats is driven back by the row of upstream seats by contact of the upstream carriage with the downstream carriage.
  • FIG. 1 the installation is divided into two juxtaposed zones that can communicate with each other, a first zone (1) for the storage of seats, a second (2) for their implementation in the multiple event room.
  • the so-called storage area has the advantage of being constituted by a volume under the stage (3), but could be the opposite, located behind the room.
  • the installation comprises ( Figures 3 and 2), on the one hand rows of seats (4) mounted on metal beams (5) resting on at least two rolling carriages (6, 6 ′), and on the other hand means for moving the seats from one zone to another and vice versa.
  • the means for moving a row of beam-mounted seats comprise motor means for driving said rolling carriages, which cooperate individually with a rail (7) for guiding and "rolling" them.
  • each rail consists of two metal beams (8) of U-shaped section, arranged in parallel, their concave part facing each other so as to form therebetween a lower and upper groove. They extend over the entire length of the first and second zones, and their upper level is slightly below the level of the floor (9).
  • the carriage comprises a chassis (10) mounted on four wheels (11) with an internal circular shoulder (12) for guiding in the lower groove of the rail.
  • the surface of rolling is carried out by the internal surface of the lower branch of each beam.
  • the linear drive motor means are produced by two synchronized chains (13) which encroach on the first zone and which extend over the whole of the second zone. They revolve around a drive gear and a return gear.
  • the chains are made up of 190 mm links and bear a breaking load of 5.6 t. calculated to move approximately 20 rows of 14 seats. Note that only the last carriages (14) are attached to the links of their respective drive chain. Without modifying the principle of the invention, it may be advantageous to fix the chain substantially in the middle of a very long carriage, common to the last two rows of seats, to allow the establishment of the last row beyond the rear idler wheel.
  • each chain is provided with individual lugs (15) for driving the carriages.
  • These cleats have a vertical attack face (16) and are spaced a length corresponding to the width of the span between two rows of installed seats. In this case, the spacing between two consecutive cleats was set at 850 mm.
  • the carriages comprise (fig.-4) an elongated protruding hooking member (17), inclined by about 30 ° relative to the vertical in the direction of the storage area.
  • This member mounted in rotation about a horizontal axis (18) of the carriage, is subjected to the tension of a spring (not shown) which tends to keep it in the projecting position.
  • the lower end (19) is intended to obstruct the attack face of the cleat while the opposite end abuts against the base of the carriage.
  • the carriage also comprises horizontal hinges formed by an axis (20) integral with the carriage and upstream and downstream articulation plates (21, 22) in two parts, a lower part and a plate of recovery.
  • the plate (21) upstream of each carriage has a recess (23) of rectangular and long cross section approximately 20 mm which allows the plate to have a longitudinal clearance (D) of approximately 15 mm taking into account the diameter of the articulation axis. It also comprises from left to right a lower flat surface terminated by a pan (24) inclined about 45 ° downwards intended to come against a stop (25) of the carriage located below the flat surface of the plate to initiate its inclination.
  • This stop appears in the figure, it has the shape of a cylinder arranged horizontally and fixed by welding to the carriage. The maximum distance between the cylinder and the inclined plane must be less than the travel of the plate (about 10 mm).
  • the carriages are connected by a connecting element (26) which allows the carriages to come together (with the possible exception of the last two rows if they have a common carriage of great length). It can be flexible in bending but rigid in traction or, as in the illustrated embodiment, it can be formed by two blades (27, 28) comprising a hinge (29) substantially central, and slightly wider than the grooves formed by the guide rails. They are each fixed to the plates by removable means, for example by screwing (30).
  • the predetermined maximum distance (L) of the pitch between two consecutive carriages is 855 mm. In the implementation, this distance is valid for all the spans but it may be advantageous to increase it gradually as a function of the distance from the stage to improve the visibility of the spectator when the floor is horizontal.
  • the seats are preferably foldable in order to be able to bring the rows as close together as possible until the carriages touch.
  • the blades are then folded, form an acute angle between them and are placed almost vertically between two consecutive rows.
  • the maximum space requirement of the seats corresponds to the cumulative length of the carriages in the contiguous position between them and the storage volume can be reduced considerably to the volume located under the stage.
  • the size can be reduced at least to half that of the seats deployed.
  • the blades appearing at each inclination of the floor are provided with several articulations which allow them to follow the possible change of slope.
  • FIG. 1a it can be seen schematically that the seats are stored under the stage. In this position, all the rows, with the exception of the last, are out of the chain, that is to say that the hooking members are out of the range of the driving cleats.
  • the chain is activated, the last (or also the penultimate) row is driven out of the storage area away from the next row while the angle formed between the two blades increases as and as the distance from the driven row moves away.
  • the angle reaches 180 °, the next row is towed outwards via the connecting blades and the distance separating the two moving carriages is then maximum (L), the upstream stage adopting the configuration (c) (fig.-7) in which horizontally, it is moved as far as possible from the stop (25) of the carriage.
  • the row arrives within range of the chain stops at a speed identical to the linear speed of the chain.
  • the stopper touches the attachment member of the carriage while it is still on the periphery of the toothed wheel. From this point and as long as the cleat describes an arc of a circle, there is a transition phase during which the drive of the carriage is relayed by the chain via the cleat and during which the row of seats being hooked is brought closer to the previous one until the distance separating it from the previous row equalizes that separating two consecutive cleats, and the plate adopts the configuration (d) in which the axis of articulation and the stop have clearance upstream and downstream respectively.
  • the chain drive is deactivated by a limit switch for example, and an immobilization system, for each cart intervenes; these may for example be brakes fixed to the rails at locations corresponding to the position of the seats and exerting friction of adjustable intensity on the chassis of each carriage.
  • Such a system can advantageously be produced by a cam rotating about an axis fixed to the rail which is pivoted by a lever connected to a common rod parallel to the rail which is actuated by a jack arranged at the end of the rail.
  • This cam comes into contact with the upper surface of the carriage and blocks its movement according to any degree of freedom. Of course other blocking means could be retained.
  • the seats are stored according to the process described below.
  • the chain is activated in the opposite direction to the previous operation and drives the last carriages to the storage area.
  • the carriage approaching the front row the cylinder comes into contact against the inclined face of the plate (in accordance with the configuration (e) fig.-7) which causes it to tilt upwards, which obviously has the effect of cause the bending of the connecting blades to start.
  • the latter continue to bend until the front of the moving carriage comes into contact with the rear of the previous carriage (configuration (f) plate raised).
  • this second carriage approaches that preceding it and operates in the same manner as above.
  • provision may be made to coat the contact surfaces with an elastic foam of the neoprene type or any other damping means.
  • attachment members are then retractable upwards from the passage of the coaching cleats; on the other hand, for correct operation of the installation, it is of course advisable to have the drive chains synchronized.
  • Sealing the grooves when the seats are stored is also effected by a covering strip (not shown), for example a flexible metal blade, elastic with the length of the rails of the area of use. This blade slides flat in lateral grooves (32) facing each other at floor level. The recovery is done at the same time as the operation of pushing the rows towards the storage area because the metal strip is hooked to the rear of the last carriage and fills the void in the groove as it moves .
  • a covering strip for example a flexible metal blade
  • this strip can be pulled on the one hand by a system of pressure rollers (not shown) located under the floor at the back of the room and on the other hand pushed by the last trolleys, a pressure roller pressing the blade against a motorized roller.
  • the rollers serve only as a guide, the lower surface of the grooves is coated with a material (31) with a low coefficient of friction.
  • the blade can be rolled up on a wheel under the floor or left in free movement.
  • the void of the rail grooves is closed by the unwinding of the blade and the floor has a uniform surface.
  • the installation has the advantage of being able to deploy a limited number of seats while operating in a relatively simple manner. It suffices to break the link between two rows before deployment. Preferably, the break is made at the level of the downstream plate of a carriage, for example by removing the screw fixing the blade to the plate.
  • the present invention finds a particularly remarkable use for floors with several predetermined slopes from which one wants to remove the seats to for example a show or a concert in which the spectator is standing. In these conditions, it is advisable to have a floor of a single relatively slight inclination (5%) to allow good visibility.
  • the invention very advantageously allows this transformation to be carried out by having a floor made up of several parts hinged together and means for lifting each part as defined in patent FR-2,500,509.
  • the seats may have, in the storage area, a rearward inclination relative to the vertical equivalent to the inclination relative to the horizontal of their corresponding floor.
