Description

Transportable grandstand

Technical field p

BACKGROUND OF THE INVENTION The invention relates to a transportable grandstand, which can be placed elsewhere, comprising stepped portions having different heights above the substrate in the utility position of the grandstand, which are telescopically extensible from each other in the horizontal pulling direction into the use position and wherein, for transporting the grandstand to another place of use, the composite step members are also located in the transport position within a predominantly prismatic support frame, i.e. predominantly in the space defined by the support frame. The individual stepped parts are either planar or stepped and can form connecting corridors and seating or standing areas for the spectator.

BACKGROUND OF THE INVENTION

According to the state of the art, the displaceable stands are assembled from individual parts into a supporting structure and are dismantled into individual parts for relocation. As a result, the assembly and disassembly of known movable stands has considerable time and assembly requirements.

Stationary grandstands are also known which retract telescopically from the stacking position, if necessary, in the horizontal pulling direction to the use position and, after use, retract into the stacking position by moving in a direction opposite to the pulling direction. These tribunes have the advantage that they can be built at relatively low cost, if necessary, and if the area occupied by the expanded tribune is to be used for other purposes, the tribune can be easily folded back into the stacking position at a low cost. However, these grandstands are stationary equipment that cannot be relocated at an acceptable cost to another location. Such a grandstand is known from FR-A-2266 783. Another telescopic grandstand which is intended for use at a fixed location of use, for example in a particular sports hall, is known from DE 7919671 UI. It consists of stepped elements that have different heights above the ground in the usable position of the telescopic grandstand. The step members are telescoping in the horizontal pulling direction into the use position and are retractable together into the stacking position against the pulling direction.

In order to be able to erect and dismantle this known grandstand at the place of use without the need for a means of transport, the grandstand has its own chassis on which the grandstand can be driven as a whole. If necessary, the grandstand can be telescopically inserted into the supporting frame. connected to the chassis and transported to another place using this chassis. Such a grandstand, adapted for a particular place of use, has the advantage that it can be driven at the place of use if necessary. However, even in these grandstands it is not possible to move it to other places of use at a reasonable cost, for example to transport it to a sports hall in another city.

DE-A-3503769 shows a container platform with a support frame from which stepped elements can be telescopically extended from the front and rear. To transport the grandstand, the stepped elements are slid into the support frame.

The prior art stands are disadvantageous in terms of achievable compactness of the stands in the transport position, the possibility of realizing transportable stands having a plurality of stepped elements. With this state of the art, it is an object of the present invention to provide an improved transportable linen stand. Assemble and disassemble without great cost and which could be moved from one place of use to another.

SUMMARY OF THE INVENTION

This object is solved by a transportable grandstand which can be placed elsewhere, comprising stepped parts having different heights above the substrate in the utility position of the grandstand, which are telescopically extending apart in the horizontal pulling direction to the payload position and retractable into the stacking position against the pulling direction. wherein, for transporting the grandstand to another place of use, the composite step members are located in a transport position within a predominantly prismatic support frame. ie, predominantly in the space defined by the support frame, which according to the invention consists in this. that some of the stepped parts are retractable into the carrier frame by means of the platform lifting mechanism and the lifting device is part of the edge of the supporting frame.

The support frame, on the one hand, assumes the static function of supporting the elements of the stands during the assembly of the stands and, on the other hand, also serves as a support element for the transport of the stepped parts inserted into one another. The support frame has a predominantly prismatic shape, i.e. its outer skirt surfaces correspond to the predominantly circumferential skirt surfaces of the prismatic container. However, the support frame need not be formed as a closed full-body or container-like container, but may be formed as an open frame or lattice structure.

Výz.naku. in that the stepped parts are stacked one above the other in a transport stack

2 of the frame, it is to be understood that the stepped parts, in their transport position, in particular over their entire length and width, are mounted in a space bounded by the circumference of the support frame. In their transport position, the stepped parts are advantageously fastened in the support frame mainly in the suspended state. The support frame may also be provided with additional fasteners for securing the position of the stepped parts within the support frame or with load-bearing support elements supporting the stepped parts from below within the support frame.

In a preferred embodiment of the invention, the support frame forms part of the grandstand and is preferably formed of profiles which are positioned in particular along the edges of the substantially prismatic basic frame shape. The frame is additionally supplemented to the extent necessary with stiffening struts and securing elements to secure the stepped parts in the transport position. The supporting frame contains a so-called three-dimensional skeleton as the basic body for transporting and standing the stands. The struts are preferably formed in the lower part and on the sides of the prismatic support frame. Further struts may be positioned at the corners or extend in the transverse or longitudinal direction, provided such stiffeners are positioned such that they do not prevent the stack of stepped parts from being extended or extended upwards.

For the carriage of the grandstand, the stepped parts are inserted into the supporting frame in which they are placed exactly one above the other in a stack or are slightly offset from each other. In this case, it may be advantageous if the stepped parts can be placed by means of a lifting device in a transport position in the support frame.

During the construction of the grandstand, the stepped parts are pulled out especially from the longitudinal side of the supporting frame from its interior space. In this case, it may be advantageous if the plurality of stepped parts are first raised above the upper side of the support frame by means of a lifting device and then the individual stepped parts are expanded horizontally apart. The lifting device is preferably an integral part of the prismatic support frame and may be provided, for example, with a spindle lifting device, a chain device or a hydraulic cylinder. Especially preferred is a spindle-drive lifting device which comprises synchronized drive means.

The grandstand according to the invention may have both standing and seating positions formed on the step sections. The seating positions may consist, inter alia, of individual seats, for example

5o shell seats which are fastened by means of a corresponding substructure to stepped parts or seats in the form of folding seats. Particularly suitable are seat elements according to DP 36 14 983 A1.

The outer dimensions of the support frame may have been adapted to the specific transport requirements, taking into account the traffic conditions, weight and number of seats in a particular grandstand design. An advantageous feature of the grandstand according to the invention may be that the outer dimensions of the support frame correspond to an integer multiple or an integer fraction of the dimensions of the standard containers. This facilitates the transport of such a frame with standardized dimensions. For example, a two-foot standard container has a length of 6055 mm. width 2435 mm and height 259! mm. The support frame according to the invention may, for example, have these dimensions or may have half or one-third lengths for otherwise the same other dimensions.

kj Another advantageous feature of the grandstand to facilitate its movement is that the support frame is provided with a conveying device for moving it by means of a conveying device, a lifting device or a conveying means, the lacquer conveying devices can advantageously be provided with loop or hook gripping elements, e.g. attaching a crane hook or crane at the lashing element. Other advantageous transport devices can be provided with a gripping device. holes; formed by, for example, pockets for inserting a fork of a stacker for moving the container. In general, the transport devices are preferably located on the upper side or lateral sides of the support frame. In particular, for transport by means of standardized transport devices it may be advantageous if the support frame is provided with the same bores as the container.

In order to achieve a low transport weight, in the preferred embodiment of the invention, the largest possible number of components of the grandstand are made of a lightweight material, for example aluminum, of which stepped parts are mainly made of this material; Supporting parts and other load-carrying parts, for example supporting frames, are advantageously made of stronger materials.

Surprisingly, it has been found in the present invention that the demanding requirements for a transportable grandstand can be met by the telescopically expandable stepped parts that are located in the support frame, since such an embodiment does not require time-consuming assembly and disassembly of a large number of grandstand components. The grandstand of the invention has the advantages of not only saving assembly time for building or dismantling the grandstand; with regard to its mobility, but also with great variability of its use.

A particular advantage of the grandstand according to the invention is also that a rigid, flat and planar substrate is not required to erect it. The location on which the grandstand is to be built may be inclined or uneven, since it is sufficient to align the support frame to a horizontal position using, for example, swinging arms or lifting spindles for the grandstand construction. The object according to the invention is achieved. that the experts have long sought.

DETAILED DESCRIPTION OF THE INVENTION

Fig. 1 shows a side view of the grandstand 1 according to the invention with stepped parts 2 stacked in this example in a stack. The stepped parts 2 comprise a front stack 3 and a rear stack 4, which are arranged in a support frame 5 that surrounds both stacks 3, 4. In another exemplary embodiment, the grandstand 1 can be folded into only one of the stacks 3, 4 shown. It is mounted on the floor 6 or other reinforced substrate and is provided with elements (not shown) which secure the stepped parts 2 against undesirable ejection. The support frame 5 is preferably designed so that it can be placed on another support frame 5 or next to an adjacent support frame 5 for transport.

In Fig. 2, the grandstand 1 of Fig. 1 is shown in a first operating position, Stage Parts 2 of the front stack

3 are pulled forward from the support frame 5. Stage parts 2 are partially telescopically spaced apart and form the front of the grandstand T Unnecessary tread parts 2 of the front stack 3 are stacked on top of each other and form the front end of the group of stair treads. the front stack 3 is connected to the support frame 5.

The grandstand 1 is composed not only of the lower part of the front stack 3, pullable forwards from the support frame 5 with the stepped parts 2, but also of the upper pull-out part. In order to lift the upper part of the grandstand 4, the rear stack 4 is partially lifted by means of a spindle-driven lifting device 7 and the necessary stepped parts 2 sc are telescopically rearwardly displaced. The upper handrail 8 is already fastened to the uppermost step 2 and must only be folded out of the stowed position and locked in the desired position. The side rail 9 is inserted into the stepped parts 2 and locked in a vertical position. Thereafter, the stair 10 is mounted rearwardly, which in the illustrated embodiment decreases rearwardly.

The front of the grandstand f, which is formed from the stepped portions 2 of the front stack 3, is supported by the front support members JM on the floor 6. The rear of the grandstand 1, formed from the stepped portions 2 of the rear stack 4, is self-supporting and therefore has no supports. This embodiment is possible because the entire depth of the grandstand 1, in particular the extension length of the upper part, is relatively small. The grandstand i is thus assembled into the first short assembly variant.

The stepped parts 2 can be provided with seats as required. A further special feature is that the support frame 5 forms part of one stage of the grandstand L on its upper side. In addition, in FIG. 2, a suitable flooring is formed in the region of the leading edge 12 on the upper side of the support frame 5. The grandstand still forms an area or staircase that can be walked from the bottom to the top.

Fig. 3 shows a side view of the grandstand 1 of Fig. 2 in a further, even more expanded position. In this example, the rear stack 4 is lifted up by the lifting device 7 from the support frame 5. The stepped parts 2 of the rear stack 4 are all telescopically expanded so that at the rear of the grandstand 1 there is

5d greater construction depth and a plurality of stepped parts 2 to be walked on. The front portion with the front stack 3 is in a position corresponding to the example of Fig. 2, but it may also be more or less stretched.

-4GB 299972 B6

The front part of the grandstand 1 is supported directly on the floor 6 by means of the front support element 11.

The front support element 11 serves to simultaneously support a plurality of stepped parts 2, but only some of the stepped parts 2 of the front part of the grandstand 1 have their own support. The stepped parts 2 are connected together by means of telescopic guides. that it is not necessary to support each step piece 2 on the floor 6 and the individual step pieces 2 can absorb forces from adjacent step pieces 2.

The rear part of the grandstand 1 is provided with a rear support element 11, by means of which the stepped parts 2 of the rear part are supported on the support frame 5. The rear support element 13 is formed by a lower part 13a. formed in the form of a reinforced triangular frame, which is pivotably attached to the supporting frame 5 by means of an articulated joint, and an upper part 13b in the form of a connecting rod which is screwed to the lower part 13a at its lower end and articulated at its upper end 2, upper part 13b of the rear support element 13, as well as? also, the front support element 11 are preferably designed so that they can pivot to a desired position from the step piece 2 on which they are articulated.

Also, in the upper part of the grandstand 1, each step piece 2 does not have a rear support element 13 for supporting on the floor 6 or on the support frame 5. but the step pieces 2 are connected together by means of telescopic guides. that they can absorb the necessary payload even without this separate support. The rear support element 11, like the front support element 11, is designed to support a plurality of stepped parts 2 connected telescopically to one another,

A particular advantage of the grandstand i according to the invention is that the grandstand i has considerable variability

2? design. Fig. 4 shows the grandstand J having the structure according to Figs. 2 and 3 in its operating position, in which the two stacks of the 4 step portions 2 are fully expanded in width, thereby forming the largest number of step portions 2 forming seating positions; stání. In contrast to the state shown in FIG. 3, the stepped parts 2 of the front stack 3 are fully extended. Since this creates a longer cantilever lining of the forward facing structure, in this example the grandstand J is provided with another front support element 11 for supporting the stepped parts 2 on the floor 6. The lower stepped part 2 of the rear stack 4 of the stepped parts 2 is connected to the support frame 5, optionally with a lifting device 7.

Giant. 5 shows a front view of an exemplary embodiment of the grandstand L shown in the side view of FIG. 4. This grandstand 1 is formed from a total of five side-by-side supporting frames 5 which are spaced apart laterally. On the side, fastening elements, which are shown in more detail in FIG. 11, are fastened to the supporting frames 5 or the respective extended stepped parts 2 and which are connected to the intermediate elements IJ of the grandstand 1, located between two adjacent supporting frames J. 1 are formed by hinged parts which are suspended between adjacent supporting frames 5. The intermediate elements 10 of the grandstand 1 may comprise stepped parts 2 or staircase parts 10 backwards or staircase 11 towards the front. The staircases 10 descend backward and the staircases 15 descend forward.

The intermediate elements 11 of the grandstand L, in particular those constituting the stepped parts 2, are hinged preferably on adjacent supporting frames 5 or stepped parts 2 of the extended frames 5, respectively, and are not supported by supporting elements on the floor 6 or on the supporting frames 5. The stands 1 are then fastened and thus supported only on adjacent supporting frames 5 or step panels 2. This facilitates the assembly and disassembly of the stands 1. The stepped parts 2 and intermediate elements 11 of the stand J are of low weight and are preferably made of aluminum.

Referring to FIG. 5, it is evident that by varying the telescopic pulling of the intermediate elements 11, the grandstand can be assembled in various arrangements consisting of rows or sectors ⁷ with or without benches or boxes. To form a broken or polygonal grandstand, they can be

5 to use intermediate segments made up of intermediate elements 14 of the grandstand 1 and interposed between two adjacent supporting frames 5 which are conical bounded.

A front view of another exemplary embodiment of a grandstand 1 having a smaller number of seats for spectators is shown in Fig. 6. The grandstand 1 comprises four supporting frames 5 and only one part of the staircase 11 descending forward. Giant. 7 shows a modification of a smaller grandstand 1 with only four supporting frames 5.

Giant. 8 shows a side view of the grandstand J as in FIG. 4, provided with a roof 16 formed of a textile roof covering 17 stretched between purlins carried by one-piece or multi-piece roof supports 18. The roof 16 can be mounted on the platform 1 as desired, and the roof supports 18 can be placed in the corner of the supporting frames 5 and on the upper end of the platform 1 in the region of the upper railing 8.

Giant. 9 shows a variation of the embodiment of the grandstand 1, which has, compared to the example shown in FIG. 4, a rear support element 11 by which the lower part of the stepped part 2 is supported on the floor 6 instead of on the support frame 5. The extension part 11 between two adjacent step parts 2, respectively. By pulling out the telescopic extension parts 19, the step parts 2 are prevented from tilting so that it is not necessary to support each step part 2 by supporting elements 11, 11 on the floor.

Giant. 10 shows a side view of a grandstand 1 formed from two support frames 5. 5a. spaced apart and parallel to each other, their upper sides being at different heights. The two support frames 5, 5a are not only differently high, but are also supported on different substrates. The front support frame 5a is built on the floor 6, while the rear higher support frame 5 is supported on a pedestal, which may be a landing or other support platform. Another preferred embodiment of the base may be a motor vehicle chassis, a traveling device or a semi-trailer 20 by means of which the support frame 5 can be transported together with the stepped parts 2 which are inserted therein. For static reasons, the semi-trailer 20 or other pedestal must be provided with extendable side outriggers 20 to ensure secure support.

The grandstand 1 is formed from both side-by-side supporting frames 5, 5a, wherein in the illustrated embodiment, no stepped parts 2 are lifted or pulled out of the front supporting frame 5a. 2, the rear stack 4 of the stepped parts 2 at the front support frame 5a can also be brought to the end position.

Giant. 11 shows in detail a cross-section of the telescopic pull-out part 11 and also the connecting elements 22 located laterally on the step parts 2. The connecting elements 22 are formed in the form of suspension rails on which the intermediate elements 14 of the stands 14 are suspended. The telescopic pull-out part 19 between two adjacent step parts 2 always comprises rollers 23 and roller guides 24.

The details of the telescopic pullout 11 are shown in Fig. 12, in which three stepped parts 2 are in the retracted storage position and three other stepped parts 2 are in the extended position. The telescopic puller 11 between two adjacent step members 2 each comprises two rollers 23 mounted on slats 25 mounted at a spaced apart distance from the step 2, which are guided and supported both above and below in the roller guides 24.

The rollers 23 have an end stop both in the fully extended and in the inserted position of the stepped parts 2. For safety reasons, these end stops are formed by locking wedges 26 which are located between two rollers 23 and in the case of damage or breakage of one roller 23 are held by the roller guide 24, so that even in this case the transmission of forces and torques is maintained.
