Definitions

  • the invention relates to a convertible, collapsible and disassemblable seat element for grandstands which, when folded, can be used as a standing platform in a standing grandstand and, when unfolded, can be used as a seat in a grandstand with seats.
  • the invention thus relates to a seat for a grandstand that can be used either as a standing or seated grandstand, in particular in a stadium or an event hall, the seat being designed as a component that can be converted between a lower standing position and an upper seated position and is permanently mounted on the grandstand .
  • the seating element In the standing room position, the seating element forms a standing step in a standing room grandstand and in the seated position at least one seat in a seated grandstand and, when permanently installed in the grandstand, can be used for standing or seating by folding or unfolding without having to assemble or dismantle it .
  • Such seating elements or stadium seats are also referred to as vario seats.
  • grandstands variably as standing grandstands or, using seating elements, as grandstands for seating.
  • the actual use of the grandstand depends on the type of event and the number of spectators to be accommodated. For example, in sports stadiums such as football or ice hockey stadiums, standing room is often offered to fans in certain areas. The conversion from seating to standing room doubles the number available Spectator seats almost so that the tickets are offered at a lower price and/or the organizer can achieve higher income. This is because the staircase or step structure of seating grandstands is usually different from that of standing grandstands.
  • a grandstand step in a seating area is generally twice as wide and twice as high as a grandstand step in a standing area, since a spectator sitting on a seating element requires additional leg and foot room and the seat, in particular the backrest, also requires a certain amount of space.
  • the use of a grandstand as a seated grandstand therefore means that the total number of seats available is reduced compared to a standing grandstand. This reduction in the overall capacity of a stadium or grandstand results in financial losses for the organizer and/or higher prices for spectators.
  • the sports fans are happy to accept the standing room offers not only because of the lower price, but also because the greater spectator density and the increased number of spectators at the corresponding events creates a more intense atmosphere in a fan block or in the entire stadium, which is for the fans and for support of the actors is very important.
  • other events e.g. B. Concerts
  • more or only seats desired in the stands e.g. B. Concerts
  • the fan area is equipped with removable seating elements.
  • the seats in the fan area are dismantled and the necessary breakwaters are installed. The seats are therefore partially removed or reinstalled. Disadvantages here are the high conversion costs, the enormous amount of work, including the associated conversion time, and the need to store the removed parts of the seat elements elsewhere.
  • a first known variant of a convertible stand-and-seat area includes a type of fixed railing bracket into which a foldable seat part is integrated.
  • the seat part can be folded up and locked when using the seat element as a standing place.
  • a disadvantage here is that in this embodiment the railing bracket is present for all seats and this creates a cage effect for the spectators.
  • Another disadvantage is that either an additional standing step is required or the standing places in two consecutive rows are always at the same height.
  • variable sit-stand system is in the EP 0 635 229 A1 described. It shows a barrier device, in particular for stadium grandstands and event halls, with a barrier device, which has vertically running strut elements which can be anchored in a foundation with their lower end and which are connected in their upper region by a cross strut element. A pivotable and lockable seat is accommodated in the barrier device.
  • the disadvantage of this device is that each seat has to be unlocked and folded out manually and that the seat elements do not fold up automatically. Furthermore, this device has limited space in the walkway area or for escape routes.
  • a second variant is known in which the seating elements are used, which as a whole are between a standing position and a Seating position can be converted by being designed as a component that can be swiveled around a joint and in the standing position form a performance area for the spectators.
  • the seat part is located under a standing step made of sheet metal profiles, which can be folded down by approx. 180° to convert it into a seat, thereby releasing the seat part.
  • the disadvantage here is that the seat height depends on the height of the grandstand step and cannot be freely specified. Therefore, this solution requires a suitable height of the grandstand steps, so that not all standing grandstands can be retrofitted with appropriate seating elements.
  • Another disadvantage is the fixed position of the seat part forming the seat, which considerably reduces the space on the walkway.
  • Such seating elements are from the document DE 36 14 983 A1 known, which refers to a horizontally telescopically extendable stand that can be pushed together into a stacked position.
  • seat elements are arranged with a backrest that can be folded down onto the seat surface, with the backrests being folded down when the stands are moved together into the stacked position by a component of the subsequent step element.
  • the well-known grandstand seat can be folded up in such a way that the seat part with the backrest placed on it is arranged below the standing platform part in the folded state, so that the standing platform part can be stepped on by one person. When unfolded, the standing platform part is below the seat part.
  • the standing platform part is pivotably fastened to a support piece, so that the sequence of the standing platform part and the seat part can be reversed in the vertical direction by a pivoting movement.
  • the seat portion is above the standing platform portion prior to pivotal movement, it will be below the standing platform portion after pivotal movement.
  • the known grandstand seat essentially fulfills its purpose, it still has the disadvantage that the height at which the seat part is arranged above the floor when the grandstand seat is in the unfolded state cannot be changed or can only be changed with great effort.
  • the depth of the floor surface on which the grandstand seat is arranged must be at least twice as great as the depth of the grandstand seat, which is essentially formed by the depth of the standing platform part.
  • a sit-stand combination for converting grandstands into standing or seating, using a pillar mounted on a step to support the sit-stand combination.
  • the pillar is independent of the sit-stand combination and pivoted to the step. In the standing position of the standing/sitting combination, it is pivoted upwards and in the sitting position of the standing/sitting combination, it is pivoted downwards.
  • the seat must be rotated about a horizontal pivot axis for conversion.
  • the document DE 10 2009 007 877 B4 describes a seat element for a grandstand that can be used either as a standing or seated grandstand, the seat element being designed as a component that can be converted between a lower standing position and an upper seating position.
  • the seat element forms a standing step in a standing room grandstand and in the seated position at least one seat in a seated grandstand. It comprises a seat part, a back part that can be folded down onto the seat part in the standing room position and a step element which, in the standing room position of the seat element, forms a step surface that covers the seat element at the top and which is supported on a horizontal step surface of a grandstand step.
  • the seat element includes a support structure with at least one fastening foot, which is designed as a folding or pivoting foot, by means of which it can be fastened to the horizontal step surface of the grandstand step located under the seat element and by a lateral step running in the longitudinal direction of the horizontal step surface, transverse to the direction of a user of the seat Folding or pivoting movement of the mounting foot can be brought from the seated position to the standing position.
  • the lateral folding or pivoting movement of the fastening foot can be carried out by a parallel pivoting device, by means of which the seat element can be converted by a lateral lifting/pivoting movement, or by a scissor lattice lifting device, by means of which the seat element can be converted by a vertical lifting movement.
  • the disadvantage of this prior art is that no individual seats can be realized with this design.
  • the variant with the lateral lifting and pivoting movement requires free space next to the seating element, and any seating that may be required there must be installed separately.
  • the document DE 10 2010 013 121 B3 describes an expandable and collapsible grandstand seat which can be fixed to a floor and has a standing platform part to which a seat part with a backrest pivotally arranged thereon is fixed.
  • the standing platform part is arranged pivotably on at least one post-shaped element, and the post-shaped element is pivotally connected to the ground at its end remote from the standing platform part.
  • the grandstand seat can be folded up in such a way that the seat part with the backrest placed on it is arranged below the standing platform part in the folded state, so that the standing platform part can be stepped on by one person. When unfolded, the standing platform part is below the seat part.
  • the standing platform part is pivotably fastened to a support piece, so that the sequence of the standing platform part and the seat part is reversed in the vertical direction by a pivoting movement can.
  • the seat portion is above the standing platform portion prior to pivotal movement, it will be below the standing platform portion after pivotal movement.
  • each seat has to be manually unlocked and folded out individually. Furthermore, this device has limited space in the walkway area or for escape routes. Another disadvantage is that the pivoting of the post-shaped element can be unlocked by unauthorized persons because the lockable joint only protects against unintentional pivoting of the post-shaped element. In addition, there is a risk of injury from the folded sheet metal arranged under the seat part. Another disadvantage is that the standing room is interrupted by a large number of gaps (approx. every 50 cm). Another disadvantage is that the seat parts do not fold up automatically.
  • the conversion is also cumbersome because the post-shaped element, the seat part and the backrest have to be moved manually, for this purpose it has to reach far beyond the grandstand seat and a counter-rotating pivoting movement of the standing platform part and the post-shaped element has to be carried out.
  • the EP 2 468 141 B1 and DE 20 2010 016 997 U1 form the from the DE 10 2010 013 121 B3 known expandable and collapsible grandstand seat further to avoid the disadvantage that there is a height difference between the standing platform parts or the seat parts of adjacent grandstand seats due to manufacturing or assembly tolerances or different weights of the grandstand seat users. If several grandstand seats arranged in a row next to each other are used as a standing platform, this can result in tripping hazards for the users of the grandstand seats due to steps or ledges at the transition points between the grandstand seats. When the grandstand seats are used as seating, occupants' clothing may become trapped in a gap between the seat portions of adjacent grandstand seats will.
  • the seating elements Furthermore, there is a desire to improve the protection of the seating elements, especially in the case of a structure as a standing room grandstand, against dirt and moisture, in order to keep the costs for cleaning to be carried out after the grandstand has been used as low as possible. Both for cleaning the grandstand and for reasons of protecting the spectators, it is desirable if the seating elements have as few protruding parts or openings as possible, especially when used as standing room.
  • the seat elements in the pivoted position of the standing room position have the lowest possible overall height, since the height of the grandstand steps can then also be designed to be low.
  • the seat element should also be designed so stable that the stepping surface forms a load-bearing structure for the spectators.
  • the object of the present invention is to create a seat element for a grandstand, which can be used either as a standing or seated grandstand, which avoids the described disadvantages of the previously known seat elements.
  • a convertible, collapsible and unfoldable seat element according to the invention for a grandstand that can be used either as a standing or seated grandstand, which, folded into a lower standing position, can be used as a standing platform in a standing grandstand and unfolded into an upper seated position as at least one seat in a seated grandstand, comprises at least one seat part and at least one associated foldable back part, which can be folded down onto the seat part when the seat element is in the standing position, can be supported on the floor of a grandstand step and forms a step surface of a standing platform that covers the seat element upwards, and can be folded up in relation to the seat part in the seated position of the seat element and one Backrest forms for the seat part, and a manually foldable supporting structure, by means of which the seat element can be fastened to the floor of a grandstand step, the supporting structure having at least one foldable fastening flap Pfuss includes and is designed such that the seat element in a vertical lifting movement by a manual folding movement of the folding foot attachment can
