Definitions

  • the present invention relates to a telescopic grandstand, for placing on a surface, comprising at least one first platform and at least one second platform, wherein the first platform is displaceable with respect to the second platform, between a retracted position, in which the first platform is situated virtually completely underneath the second platform, and an extended position, in which the first platform extends virtually completely in front of the second platform, and comprising at least one pressure-distributing element to distribute the load of the first platform over the surface.
  • this telescopic grandstand is suitable for placing on a sports floor as surface.
  • Such telescopic grandstands which can be placed on a sports floor, are typically configured to be arranged in a sports venue, where, depending on the use of the venue, the floor has to be cleared for sports activities or a (seated) grandstand is desired which takes up a part of the floor in order to accommodate (seated) spectators.
  • these grandstands In their retracted state, these grandstands may be very compact, with several platforms being arranged one above the other. In the extended state, the platforms are then arranged in a stepped manner with respect to each other. These platforms may optionally be provided with folding seats.
  • a problem of telescopic grandstands for placing on a sports floor is the fact that such a sports floor is particularly susceptible to damage.
  • Such a sports floor is typically able to absorb high loads for a short time, but is less well able to absorb loads for a longer period of time.
  • a sports floor may become permanently damaged.
  • such a sports floor is typically reinforced at the location of such a telescopic grandstand, which does, however, not benefit the resilient properties of such a sports floor. Such a reinforcement is therefore prevented or limited as much as possible.
  • pressure-distributing shoes or blocks are arranged next to the wheels, thus making it possible to roll platforms of such a grandstand on a surface.
  • these pressure-distributing blocks are situated at a certain intermediate distance from the surface.
  • These pressure-distributing blocks are sprung by means of mechanical springs or gas springs, so that these can sink under the weight of spectators taking a seat on the grandstand in order to be supported on the surface. Examples of such solutions have been described and illustrated in FR 2 746 433 Al, US 3,222,827, DE 24 56 697 Al and DE 298 13 512 Ul.
  • a further drawback is the fact that such pressure-distributing blocks can only distribute the load over a limited surface area, as a result of which the sports floor still has to absorb high local loads.
  • WO 2006/076772 Al already describes an alternative solution, in which the load of the grandstand can also be distributed over the surface during prolonged extended states.
  • the pressure-distributing blocks can also sink under the weight of spectators, but they can also be manually or automatically pulled up or lowered as desired, in an active manner.
  • the lowering of these pressure- distributing blocks requires an intentional active action.
  • the load is also still distributed over a limited surface area, as a result of which the sports floor still has to absorb high local loads.
  • the wheels by means of which the platforms are displaceable are rolled onto pressure- distributing plates, which are lowered for this purpose, when extending the grandstand, just before the completely extended state thereof.
  • the wheels are rolled off these pressure-distributing plates again and these pressure-distributing plates are pulled up again.
  • the load of this grandstand is always distributed over the pressure-distributing plates in the extended state of the grandstand, without this distribution depending on the weight of spectators who are seated on this grandstand and without requiring a separate action for this.
  • the pressure plates have to be provided with relatively large openings in order to enable the wheels to extend through these so as to be able to retract and extend the grandstand.
  • the lifting and lowering of the pressure plates also requires a relatively complicated system.
  • the object of the present invention is to provide such a telescopic grandstand which is provided with a simple system by means of which an improved distribution of the load of the grandstand over the surface can be achieved in all circumstances.
  • a telescopic grandstand for placing on a surface, such as a sports floor, comprising at least one first platform and at least one second platform, wherein the first platform is displaceable with respect to the second platform, between a retracted position, in which the first platform is situated virtually completely underneath the second platform, and an extended position, in which the first platform extends virtually completely in front of the second platform, and comprising at least one pressure-distributing element to distribute the load of the first platform over the surface, wherein the pressure- distributing element is configured as a guide element for guiding the sliding movement of the first platform over the surface.
  • the pressure-distributing element is now configured as a guide element for guiding the sliding movement of the first platform over the surface, this pressure- distributing element no longer has to be lifted up or held up in order to be able to move the first platform.
  • the pressure-distributing element can always remain positioned at the same distance on or just above the surface. This pressure- distributing element can thus remain lowered at all times in order to both guide this sliding movement and to distribute the load of the first platform over the surface, both when the grandstand is empty and when spectators are seated thereon. In this way, the load of this grandstand is always distributed over the pressure-distributing plates, without this distribution depending on the weight of spectators who are seated on this grandstand and without requiring a separate action for this.
  • this pressure-distributing element can be incorporated in the grandstand using a simpler mechanism than is the case with the prior art. Such a simpler mechanism may also be made more lightweight which again benefits the load of the surface.
  • this pressure-distributing element no longer has to be able to move up and down between running wheels, so that this can be designed over a larger surface area than any prior-art pressure-distributing element in order to rest on the surface.
  • the larger this surface the better the distribution of the load over the surface.
  • a pressure-distributing element as a guide element, running wheels no longer have to be provided in order to make the first platform rollable over the surface.
  • this first platform may be made displaceable only with respect to this surface.
  • at least one such pressure-distributing element is provided on at least both sides of the first platform, so that this first platform remains supported on both sides during the sliding movement.
  • all platforms which are displaceable with respect to the second platform are provided (on both sides) with at least one such pressure- distributing element.
  • each of these first platforms is preferably provided with at least one such pressure- distributing element and still more preferably provided with at least one such pressure-distributing element on either side thereof.
  • a telescopic grandstand also comprises drive means for driving the sliding movement of the first platform, so that this can automatically be extended and/or retracted.
  • These drive means then preferably comprise a push chain.
  • Such a push chain is able to transmit both pulling force and pushing force, by means of which the grandstand can be retracted as well as extended.
  • By means of such a push chain it is possible to ensure that the load on the surface is reduced compared to other typical drive means, and this in the zone where this surface is either cleared by the grandstand in the retracted state of the grandstand or occupied in the extended state of the grandstand.
  • this push chain may, for example, be accommodated in the grandstand, as is described in EP 2 345 780 Al, the contents of which are deemed to be incorporated by reference.
  • the drive means may be provided with one such push chain or they may be provided with several push chains which are arranged distributed along the width of the grandstand and are preferably driven synchronously.
  • the pressure-distributing element of a grandstand according to the present invention is configured as a pressure-distributing plate. In the form of a pressure-distributing plate, such a pressure-distributing element can easily be made strong and lightweight.
  • such a pressure-distributing plate preferably comprises a base for supporting the pressure-distributing plate on the surface and two flanges which stand upright on both sides with respect to this base in order to provide optimum guidance of this pressure-distributing plate over the surface.
  • this pressure- distributing plate may also be provided with an upright flange on the front side and the rear side in order to further optimize guidance of the pressure-distributing plate on the surface.
  • a pressure-distributing element for a grandstand according to the present invention may, more specifically, be made of metal.
  • a said pressure-distributing plate with upright flanges may, more specifically, be formed by means of folding, in which case the upright flanges are folded with respect to the base.

  • a single belt is provided, but, if desired, it is also possible to arrange several belts next to each other. It is likewise possible to arrange several of said return wheels next to each other for supporting one or several such belts.
  • the return wheels are preferably arranged directly on the said ends of the pressure- distributing element, but, if desired, it is also possible to arrange several successive pressure-distributing elements between both return wheels.
  • the return wheel on the front side of the pressure-distributing element is preferably arranged virtually at the location of the front side of the first platform.
  • the return wheel on the rear side of the pressure-distributing element is preferably arranged virtually at the location of the rear side of the first platform.
  • the said return wheels are preferably not driven directly by means of drive means, but only arranged so as to be rotatable, so that they only rotate when this is being caused on account of the sliding movement.
