To facilitate the assembly and disassembly of a mobile podium (1) the invention provides for the step elements (2) to be configured such that they can be extended telescopically and to be arranged in a substantially cuboidal support frame (5).

Description

The invention relates to a portable, for use provided at different places of use and installation or suitable grandstand with step elements, which in one Use position of the grandstand at different heights have a floor. The individual step elements are each formed either flat or stair-shaped and can connect walkways, seating or standing room include.

According to the state of the art, portable stands are assembled from individual parts to form a load-bearing framework and disassembled for transportation. This has the consequence that the assembly and disassembly of the known portable stands require a lot of time and assembly is required.

In addition, stationary stands are known, which consist of a Stack position, if necessary, telescopically in a horizontal Extension direction pullable into the position of use and after use in the opposite direction to the extension Stackable are collapsible. Have these bleachers the advantage that they can be built relatively inexpensively if required and, if the one covered by them Area needed for other purposes, inexpensive in the stack position can be pushed back. Indeed are these grandstands stationary, which does not come with a reasonable effort other locations can be moved. Such a grandstand is known from document FR-A-2266 783. Another telescopic grandstand designed for use a fixed location, for example in a specific one Sports hall is provided is from document DE 7919671 U1 known. It has step elements that are in a position of use of the telescopic grandstand different Have heights above a floor. The step elements are telescopic in a horizontal extension direction in the position of use can be pulled out and against the direction of extension collapsible into a stack.

So that this known grandstand can be used at its place of use can be set up and dismantled without this requires a means of transport, she points out a chassis with which it can be moved as a whole. If necessary, the grandstand can be telescoped on the Push the support frame connected to the chassis together and move it to another location using the undercarriage. This is intended for a specific location Grandstand has the advantage that it can be used at the place of use can be moved. However, it is also at these grandstands not possible, they with a reasonable Effort to other locations, for example in one Spend another city's gym.

Document DE-A-3503769 shows one Container stand with a support frame, made of the front and back step elements can be extended telescopically. To the Transporting the grandstand will be the step elements pushed into the support frame.

Those known from the prior art Grandstands are disadvantageous with regard to the achievable compactness of the grandstand in the Transport location, the possibility of realization of portable grandstands with a higher one Steep slope as well as grandstands, one have a larger number of step elements.

The present invention takes this state into account the technology based the task, an improved portable grandstand to create, which are easy to assemble and dismantle can be moved from one location to another.

This task is performed by a grandstand with the Features of claim 1 solved.

The idea on which the invention is based is telescopically extendable and collapsible step elements to be arranged in a support frame, which both at the installation of the grandstand static, supporting the grandstand Functions as well as for transporting the pushed together step elements serves. The support frame is essentially cuboid, i.e. its outer envelope surface corresponds essentially to that of a cuboid Container. However, the support frame does not have to designed as a closed container like a container but can also be used as an open supporting structure will be realized.

The feature that the stacked in the transport position Step elements are arranged within the supporting frame, it's so. to understand that they are in the transport situation in essential, preferably entirely in that of the support frame delimited space. The step elements are preferably essentially hanging in the transport position fixed in the support frame. But there can also be additional ones Fixing elements for fixing the position of the Step elements in the support frame or load-bearing Support elements for supporting the step elements in the Support frame should be provided down.

The support frame forms an integral part the bleachers. It is advantageously made Profiles composed, preferably along the Edges of the substantially cuboid basic shape arranged are. In addition, to the extent necessary Stiffening struts and securing elements for securing to provide the step elements in the transport position. The support frame has a three-dimensional, so to speak Scaffold as a basic body for transport and installation the grandstand. The struts are preferred in the bottom as well as in the side parts of the cuboid Support frame attached. Further struts can be found in attached to the corner areas or across or lengthwise if they are arranged so that they are Do not hinder the stack from being pulled out or raised.

To transport the grandstand, the step elements are in inserted the support frame in which they are flush or take stack position slightly offset from each other. there it is advantageous that some of the stacking elements by means of a lifting device in a transport position in the Support frame can be brought.

To build the stands, the step elements are preferred over the long side of the support frame, from which Support frame pulled out. It can be advantageous if some of the step elements by means of a lifting device initially beyond the top of the support frame can be lifted and then pulled out. The Lifting device is advantageously in the cuboid Integrated support frame and can for example by means of a spindle drive, a chain hoist or hydraulic be realized. One embodiment is particularly advantageous with spindle drives, which preferably synchronized Include gears.

The grandstand according to the invention can be both standing and Have seats on the step elements. The seats can be in the form of individual seats, For example, bucket seats can be provided, for example on appropriate substructures on the Step elements can be mounted or designed as folding seats are. Seat elements are particularly preferred according to document DE 3614983 Al.

The outer dimensions of the support frame can be taken into account of transportation requirements, weight and the number of seats according to the respective requirements be interpreted. An advantageous feature can be found in it exist that the outer dimension of the support frame in major integer multiples or integer numbers Parts correspond to the dimensions of standard containers. This simplifies the transport of the standardized in this way Size. For example, has a 20 foot standard container a length of 6055 mm, a width of 2435 mm and a height of 2591 mm. A support frame according to the invention can have these dimensions, for example, or with otherwise the same dimensions, about only half or one be three times as long.

Another beneficial feature to facilitate the Transports can consist in that the support frame transport devices for transport using a transport device, a hoist or a conveyor having. Such transport devices can advantageously loop or hook-shaped attack elements, for example to attach a crane hook or a crane harness. Other advantageous transport facilities can have engagement openings, for example Bags for inserting forklift forks Move the container, be. General are the transportation facilities advantageously above and / or laterally arranged on the support frame. In particular, it can for transport with standardized transport equipment be advantageous if the support frame corresponding Has engagement openings as in a container.

Advantageously, to achieve a low Transport weight as many parts of the grandstand as possible a light material, such as aluminum. This applies in particular to. the step elements. supporting and load-bearing parts, such as the support frame, are preferred, however, in a firmer Executed material.

In the context of the present invention, surprisingly found that the difficult requirements In the case of portable stands, they can be extended telescopically Step elements arranged in a support frame are, can be solved without a time-consuming Assembly or disassembly of many individual parts is required. The grandstand according to the invention has but not just advantages in terms of time requirements for assembly and dismantling as well as with regard to their mobility on, but is also very versatile.

A particular advantage of the grandstand according to the invention further consists in the fact that no firm, straight, level surface is required. The Place on which it is placed can be an incline have or be provided with bumps, as it is for the structure of the grandstand is sufficient, the support frame align horizontally, for example using of swivel supports or spindles. With the invention goals are achieved, around which the experts already care tried for a long time.

In Fig. 1 is a side view of an inventive Grandstand 1 with step elements 2 shown in a stacked position. The step elements 2 comprise a front one Stack 3 and a back stack 4. They are in one Support frame 5 arranged, which surrounds the two stacks 3, 4. In other embodiments, only one of the two stacks 3, 4 may be provided. The support frame 5 stands on the floor 6 or another surface and has securing elements, not shown, by means of which the step elements 2 against an unintentional Are secured. The support frame 5 is advantageously trained so that he for transportation other support frames stacked on top of or next to each other can be.

In Fig. 2 the grandstand 1 of Fig. 1 is in a first Position of use shown. The step elements 2 of the front Stacks 3 are forward of the support frame 5 pulled out. The step elements 2 are partially telescopic pulled apart and form a front Part of a grandstand 1. The step elements not required 2 of the front stack 3 are stacked on top of each other and form the front end of the extended step elements 2. The upper step element 2 of the front stack 3 is connected to the support frame 5.

The grandstand 1 does not only include a lower one, from which Transport position can be pulled out from the support frame 5 to the front Part with step elements 2, the front stack 3, but also an upper one, compared to the transport position raised position to the rear out of the support frame 5 extendable part with step elements 2, of the rear stack 4 is formed. To take off the Upper part of the grandstand 1 is the rear stack 4 by means of a lifting device formed by a spindle drive 7 partially raised and the required level elements 2 are extended telescopically to the rear. The upper railing 8 is already on the top step element 2 attached and only needs to be unfolded and locked become. The side railings 9 are in the step elements 2 inserted and locked. Furthermore, a staircase 10, the in the example shown, it slopes downwards, assembled.

The front part of the grandstand 1, which consists of the step elements 2 of the stack 3 is formed by means of a supported front element 11 on the floor 6. The rear, from the step elements 2 of the rear stack 4 formed part of the grandstand 1 is self-supporting, so has no support element. This is shown in the Example possible because of the full depth of the grandstand 1, especially the length of the extract in the upper Part, is relatively low. Grandstand 1 is in one first, short installation variant.

The step elements 2 can be fitted with seats as required be provided. Another specialty is that the support frame 5 at its top part of a Level of grandstand 1 forms. 2 is in Area of the front edge 12 at the top of the support frame 5 a suitable floor, for example a stable one Board, assembled. The grandstand 1 thus forms one surface accessible from bottom to top or Stairway.

3 shows a side view of the grandstand 1 Fig. 2 in a more extended position of use. For this is the rear stack 4 by means of the lifting device 7 completely lifted out of the support frame 5. The step elements 2 of the rear stack 4 are all telescopic extended so that in the rear part of the grandstand 1 a greater depth and a larger number of accessible Step elements 2 results. The front part with the front stack 3 corresponds to the position in Fig. 2, can but also be pulled out more or less.

The front part is by means of a front support element 11 supported directly on the floor 6. The front one Support element 11 serves for simultaneous support several step elements 2; not all step elements 2 the front part of the grandstand 1 have its own support on. The step elements 2 are by means of the telescopic guide interconnected so that no support each step element 2 on the floor 6 is required and the individual step elements 2 mutual forces be able to record.

In the rear part of the grandstand 1 is a rear support element 13 provided, by means of the step elements 2 the support frame 5 are supported. It includes a lower one Part 13a in the form of a stiffened, triangular Frame, which is pivotally hinged to the support frame 5 and an upper part 13b in the form of a connecting rod, the one at its lower end with the lower part 13a screwed and with its upper end to a step element 2 is articulated. The upper part 13b of the support element 13 is like the front support element 11, advantageously designed so that it from the Step element 2, on which it is articulated, pivoted out can be.

Also in the upper part of the grandstand 1 not every step element has 2 a rear support element 13 for support on the floor 6 or on the support frame 5, but the Step elements 2 are so together through the telescopic guide connected that even without such supports can take the required load. The rear Support element 13 is like the front support element 11, for supporting several at the same time, telescopically interconnected step elements 2 formed.

A particular advantage of the grandstand 1 according to the invention is that it can be built variably. 4 shows the grandstand 1 of FIGS. 2 and 3 in a position of use in which the two stacks 3, 4 completely are extended and thus the largest number of step elements 2 is available for seating or standing room. Compared to the structure in Fig. 3 are the step elements 2 of the front stack 3 fully extended. Because of the Another cantilever is a further support element 11 for supporting the step elements 2 on the Floor 6 provided. The lower step element 2 of the rear Stack 4 is with the support frame 5 or the lifting device 7 connected.

5 shows an exemplary top view of a Grandstand 1, the side view of which is shown in FIG. 4. It consists of a total of five arranged side by side Support frame 5 constructed with a lateral distance are positioned to each other. On the side of the support frame 5 or the associated extended step elements 2 Connecting elements, which are explained in more detail in FIG. 11, arranged with between each two adjacent Support frame 5 arranged grandstand intermediate elements 14th are connected. The intermediate grandstand elements 14 are hanging parts, between two adjacent support frames 5 be hung up. The grandstand intermediate elements 14 can Form step elements 2 or stair elements 10, 15. Stairs that fall backwards are marked with 10 and stairs that drop forward at 15.

The intermediate stands 14, in particular those the step elements 2 form, are preferably only on the laterally adjacent support frame 5 or from suspended the support frame 5 extended step elements 2, without supporting elements on the floor 6 or are supported on the support frame 5. The intermediate stand element 14 are then only on the neighboring Support frame 5 or step elements 2 attached and supported. This facilitates the assembly and disassembly of the Grandstand 1. The step elements 2 and the intermediate grandstand elements 14 are preferably lightweight, for example made of aluminum.

5 can also be seen that by modified telescopic pull-outs and intermediate elements 14 the grandstand 1 in various ways in rows or sectors Can be built with or without gangs and with or without boxes is. To form an angled or polygonal Grandstand 1 can also consist of grandstand intermediate elements 14 intermediate segments formed between two neighboring ones Support frame 5 may be provided, which are conically limited.

A supervision of another embodiment in which the number of places is less is under supervision shown in Fig. 6. The grandstand 1 comprises four supporting frames 5 and only one stairway 15 forward. The Fig. 7 shows a modification of a smaller grandstand 1 with only four support frames 5.

8 shows a side view of a grandstand 1 like Fig. 4 with a roof 16 made of a textile roof skin 17 between purlins made of one or more parts Roof supports 18 are worn. The canopy 16 can be installed as required on grandstand 1, whereby the roof supports 18, for example on the corner points of the Support frame 5 and at the upper ends of the stands in the area of the upper railing 8.

Fig. 9 shows a modification of a grandstand 1, the opposite the embodiment shown in Fig. 4 has rear support member 13 which the upper part the step elements 2 on the floor 6 instead of on the support frame 5 supported. Furthermore, the telescopic extension is in this figure 19 shown between adjacent step elements 2. Through the guidance in the telescopic pull-outs 19 tilting of the step elements 2 prevented, so that not each step element 2 by means of support elements 11, 13 the bottom 6 must be supported.

10 shows a side view of a grandstand 1 with the peculiarity that they consist of two at a distance parallel to each other and with their top edge in different Support frame 5, 5a arranged at heights is. The two support frames 5, 5a are not only different high, but are also on different Substrates. The front support frame 5a stands on floor 6, whereas the rear, higher support frame 5 is arranged on a base. The Underframe can be a pedestal, for example. A another embodiment of a suitable base can be a movable chassis, chassis or a semi-trailer 20, by means of which the support frame 5 with step elements 2 inserted therein are transported can. For static reasons can be used as a support Side arm 21 on the base or the semitrailer 20 may be provided.

The grandstand 1 is arranged side by side by the two Support frame 5, 5a formed, in which shown Example no step elements 2 from the front Support frame 5a are raised and extended. If the rear support frame 5 arranged at a greater height is or its front step elements 2 only partially the rear stack 4 of the front stack Support frame 5a are used.

11 shows in a partial section details of the Telescopic extension 19 and the side of the step elements 2 arranged connecting elements 22. The connecting elements 22 are designed as hanging tabs in the intermediate stands are attached. The telescopic extension 19 between two adjacent step elements 2 each comprises rollers 23 and a roller guide 24.

Details of the telescopic extension 19 are shown in Fig. 12, in which three step elements 2 are inserted Stack position and three step elements 2 in the extended position. The telescopic extension 19 between comprises two adjacent step elements 2 each two on the lower step element 2 on a tab 25 and rollers 23 arranged at a distance from one another, those arranged in the upper step element 2, the rollers 23 support both upwards and downwards Roller guide 24 run.

The rollers 23 have both in the fully extended also in the fully inserted position of the step elements 2 an end stop. For security reasons Safety wedges 26 are provided, each between two Rollers 23 are arranged and in the event of breakage one Roller 23 are held by the roller guide 24, so that in this case, the step elements 2 are not separate from each other and the power and torque transmission is guaranteed.
