The invention addresses the problem of providing a portable stage platform and dedicated platform elements, wherein their component structure minimizes the weight to be handled by operators and make the elements with relatively simple assembly and disassembly the use of additional tools largely unnecessary.

The invention solves this problem by forming the pedestal elements with the features of claim 1. With regard to further embodiments of the platform pedestal invention reference is made to claims 2 to 14.

For a transportable stage platform nestable podium elements are provided, which have an additional connection assembly in the region of a supporting frame delimiting a plate core. This podium elements are inventively designed so that starting from a support plate core of lightweight material receiving support frame for handling optimally low weights having functional unit is achieved. In this case, a combination of optimized individual parts is realized, such that the modular podium elements are each constructed of a multi-part and application-compatible combined mounting structure and are provided cost-effectively in large quantities.

The optimized structure has a board core made with assembly contours, wherein a support frame is fixed to this base part and a top and bottom plate glued to these parts stiffen the mounting structure as a whole. The semifinished product or intermediate product prefabricated therewith can be provided with application-specific, variably predefinable positions - in particular on the circumference of the frame - with the plug-socket system forming a holding unit, so that stage platforms, presentation surfaces, combined wall-floor groups or the like. Usable areas can be easily constructed and quickly disassembled.

These with a view to a rigid structure weight-optimized podium elements have a tool-less manageable at their collapsing or disassembling plug-socket system, so that even less trained operators a simple and optimal for a repeated change of operating positions stringing the elements to a stage platform possible becomes. In each case, only the elements of the plug-socket system are to be connected, such that "loseable" items or additional tools are not required both during assembly and during disassembly. Rather, a "captive" holding unit is realized with the plug-socket system according to the invention, which allows a sufficiently stable fixation only by the two connection profiles and thereby implements an advantageous one-piece design of the platform elements.

This "self-locking" concept of provided with the holding unit podium elements is - with optical and application technology improved design means in the field of their individual parts - designed so that all structures the connector socket system provided as a connector are concealed in the position of use or be integrated into the support frame. At the same time, a particularly suitable upper-side useful surface is provided, which also has disadvantageous contours in the abutment region of side surfaces of the adjacent pedestal elements without stumbling edges or the like ,

This construction of the pedestal elements provides that the side profile parts forming the support frame enable optimum integration of the plug-socket system acting as a holding unit.

With these integrated into the respective holding unit holding parts of the principle of a simple form-fitting support outgoing male-female composite is additionally stabilized and the entire system in the mounting position "elastic" stiffened. This additional stiffening is advantageously already achieved in that on the respective bushing profile of the system consisting of a wear-resistant and permanently elastic material insert sleeve or insert sleeve is provided as the additional holding part. This holding part is dimensioned and arranged in the region of the support frame so that the plug inserted or inserted in the connecting position can be applied radially and / or axially to the preferably elastic holding part and thus a static as well as dynamically highly resilient fixation is formed.

It is advantageously provided for the optimal connection production, that the holding part located in the bushing profile is formed in the form of a radially open half-shell and in this the plug is comparatively easy to insert or insert. Likewise, the plug can be shaped so that in interaction with the elastic insert a locking of the connecting parts is possible.

For a preparation technically simple preparation of this connection structure is provided that the system has as the plug respective fixable on the side profile parts and engaging in the support frame Schraubstifte. These are dimensioned so that an optimal engagement length is achieved in the region of the support pin projecting beyond the bushing profile.

The construction of the platform elements provides in the region of the support frame that at least one support foot per plate element can be fixed to this in each case. It is advantageously provided that the support frame is provided in the region of its support blocks with respective connecting contours receiving the support legs. The stability of the platform in the position of use is increased by the fact that several support feet in each case in the area between the socket or plug profile on the side profile parts of adjacent plate elements attack.

In Fig. 1 is shown in a partially sectioned bottom view a generally designated 1 podium element, with a in Fig. 7 shown stage platform P can be constructed from several of these transportable parts. A plurality of pedestal elements 1 can be placed against each other in this assembly (arrow M) on at least one side of the peripheral contour, so that a stable connection is achieved. Such podium elements 1 have in a known per se in the region of a plate core 2 to this limiting support frame 3, so that a stiffened and pressure-resistant podium element is created.

These pedestal elements 1 usually consist of multilayer wood panels, these being enclosed by a steel or aluminum parts having support frame. In the event that such "wood panels" are not placed on a support structure, the attachment of plug or telescopic feet is provided in known constructions. In the conventional construction auxiliary tools such as wrenches o. The like. Used to make the connection or to fix the respective feet on the support frame. Due to the multi-layered design of the plate cores, the known platform elements 1 have a high weight, so that only adult assistants an installation of the system, for example when building a dance floor ( Fig. 7 ).

The inventive design of the platform elements 1 provides that they are provided with a plate core 2 of lightweight material receiving support frame 3, so that the handling of these "lightweight elements" is already simplified by low weight. The optimally provided podium elements 1 continue to be provided with a connection system in the form of a Fig. 3 ) or disassembling tool-free plug and socket system A ( Fig. 4 ) is trained. This functional unit is designed in such a way that, in particular, in the case of pod elements 1 (FIG. Fig. 4 . Fig. 7 ) the plug socket system A is completely covered.

The disk core 2 ( Fig. 5 ) is advantageously formed as a sandwich plate, which consists of a core 4 made of XPS foam - an extruded polystyrene - and this is flame retardant ( Fig. 5 ). A respective bottom 5 of the pedestal element 1 also consists of a laminate and / or GfK material from the viewpoint of weight saving. This high-pressure laminate is also provided in the region of an upper side 6, wherein this additionally may have an anti-slip structure.

Starting from this functionally optimized construction of the platform elements 1, the support frame 3, which is preferably made of hard PVC, is provided with respective side profile parts 7, 8 or 9, 10 (FIG.

For optimal stabilization of the system is provided that in each case two of the adjacent side profile parts 7, 8, 9, 10, two of the plug 12 and two of the sockets 13 are attached and these form the plug-socket system A as the respective shape areas. Thus, the mutual mounting position ( Fig. 7 ) are produced with little effort.

The composite system according to the invention enables optimum connection production in that the bushing 13 (FIG. Fig. 2 ) is formed as a downwardly open half-shell 15, so that the plug 12 optionally in the socket 13 - or vice versa - inserted (arrow M ', Fig. 4 ) or - as in Fig. 3 represented by arrow M - can be inserted in a direction extending substantially perpendicular to the plane of the plate connecting direction. In this connection position ( Fig. 4 ) are then different ways of additional locking and / or fixing position conceivable; in any case, this is achieved without additional auxiliary tools. A particularly advantageous - and optimal for highly loaded conditions of use of the plug-socket system A - version of the system is achieved in that in the area of the socket 13 and / or the plug 12 in a mounting position ( Fig. 4 ) a press-connection forming holding part 14 ( Fig. 3 ) is provided. This holding part 14 can be manufactured as an insert sleeve or insert bush, so that corresponding contact areas are defined. Advantageously, the holding part 14 consists of a wear-resistant and permanently elastic material, wherein at this the inserted plug 12 is radially and / or axially applied. This in Fig. 4 shown connection position is optimized in that a shaping lug 20 of the plug 12 engages in a mold cavity 21 of the bushing 13 and thereby in the adjacent abutment region 22, the elastic holding member 14 is effective.
