Floor covering device for platform systems, stands and podiums

TECHNICAL FIELD

[0001] The present invention relates to a floor covering device for platform systems, stands and podiums, or similar event systems, with a floor covering, support edge profiles arranged in the edge area of the floor covering. floor, in which the floor covering is housed and which have at least one respective cavity that is open towards the corner area and which in particular is continuous in the longitudinal direction, a corner connection unit with two arms connected to the support edge profiles that are in contact with each other in the corner area, and a snap-in housing unit connected to the corner connection unit for releasable connection of a snap-in leg. [0002] These components must be easy to assemble and lightweight to be able to use them economically by hand and without using cranes. In addition, a simple and reliable connection technique must be given.

CURRENT STATE OF THE TECHNIQUE

[0003] DE 4028936 A1 discloses a floor covering device of the type mentioned in the introduction. It is a set of assembly that presents groups of frame pieces of profiles with equal lengths in pairs for the construction of superstructures of different sizes in the form of a frame. In this context, a group of four support profiles of the same length from approximately one door height to the floor height and at least four housing cages are used for the end of a respective support pillar that can be screwed at the corners of the superstructure frame. These cages have interior wedge surfaces in each of which a sliding wedge, which can be manually unlocked, is guided as an automatic immobilization element for the corresponding support pillar. [0004] WO 2010/126446 A1 discloses a floor covering device with edge profiles configured as hollow profiles, the corner connection being formed by an L-shaped arm piece that is inserted respectively into the profile of frame connected in the corner area. The frame profile also has a wedge head connection that can be releasably connected to a connection rosette of a support profile. [0005] Document NL 1022821 C2 discloses a floor covering device with edge profiles configured as hollow profiles on which the floor covering is placed. The frame profiles are joined together in the corner area by inserting L-shaped corner connectors, the corner connectors presenting a housing profile for a snap-in leg, configured as a grooved hollow profile. In this housing profile you can insert a snap-in leg that is snapped into the housing profile. [0006] US 2009/252550 A1 discloses a floor covering device with frame profiles that are connected to each other in the corner area by means of a corner connector and on which underside a support profile is connected. [0007] A floor covering device disclosed in EP 1370763 B1 is used in the framework of a system of construction elements that has been successful in practice and is used in multiple applications. Within the framework of making large lining surfaces available, floor covering devices of this type are placed side by side and hung through support edge profiles on main support profiles, which are connected to their once with uprights present in the corner area. The proven connection technique of the Layher-Allround scaffolding system (registered trademark) is used as the connection technique, in which the slotted connection heads of the main support profiles slide on a perforated disk present in the post and then connect by hitting a wedge. The uprights can protrude above the corresponding floor covering devices, so that other building elements can be connected at height. [0008] However, situations of use are also possible in which the provision of uprights is dispensed with and only plug-in leg profiles that do not protrude above the level of the floor covering device are connected from below. For this, an independent snap-in leg support is used, which has L-shaped arms that are screwed onto the inner face of the support profiles in the corner area with the outer face of the wall of the support edge profiles. of the floor covering device. On the inside of the L-shaped profile, a grooved tube section is welded into which a snap-in leg can be inserted, which can then be fixed under pressure. [0009] As part of an optimization of this type of floor covering devices, in particular with regard to a reduction in weight to facilitate assembly, the support edge profiles are configured with increasingly thin walls, so that the known snap-in connection devices are reaching the limit in terms of stiffness and load capacity required.

[0024] Detail A, that is, the corner area, is shown in more detail in Figures 1 to 5. Figure 1 shows detail A in an exploded view from below. [0025] The floor covering device 10 has a first support edge profile 14.1 and a second support edge profile 14.2. The two support edge profiles 14.1, 14.2 have a different cross-sectional profile whose loading capacity is optimized on the basis of the predetermined geometry of the floor covering device 10. The two support edge profiles 14.1, 14.2 directly present below the support surface of the floor covering 12 a first and a second cavity 16.1, 16.2 continuous in the longitudinal direction and open towards the corner area, which have the same configuration with regard to their cross-sectional geometry and which are arranged at the same height level in the corner area. In the corner area there is a corner connection device 18 configured as an extruded profile. The corner connection unit 18 has a first arm 20.1 and a second arm 20.2 that are configured as hollow profiles with a first continuous transverse recess 30.1 and 30.2, respectively. [0026] In addition, an insert 32 is provided that has a rectangular cross section of solid profile corresponding to the inner peripheral contour of the first or second transverse recess 30.1, 30.2, and which can be introduced in positive connection in the first transverse recess 30.1 or the second transverse recess 30.2, respectively. When the insert 32 is inserted, its upper face and its lower face are level with the first arm 20.1 and the second arm 20.2, respectively. [0027] The first arm 20.1 is at right angles to the second arm 20.2, corresponding to the connection angle of the first support edge profile 14.1 with the second support edge profile 14.2. The cross section of the first arm 20.1 and the second arm 20.3, is configured perpendicularly to the longitudinal direction such that the first arm 20.1 and the second arm 20.2 can be introduced into the cavities 16.1 and 16.2 of the support edge profiles 14.1 and 14.2, respectively. [0028] The insert 32 has complementary connection means 26 which are configured as two nuts arranged in separate places in the longitudinal direction and which are fixed within the solid cross-section of the insert 32. The insert 32 it can be configured for example as a plastic building element produced by injection molding. At the same time, the insert 32 is approximately in the middle with a recess of the insert 38. [0029] The inner wall of the first arm 20.1 or the second arm 20.0 has two separate corner connector recesses 42 which, when the insert 32 is inserted, they are aligned with the complementary connecting means 26 (nuts) of the insert. Furthermore, between the corner connector recesses 42 an arm connection recess 44 is provided which, when the insert 32 is inserted, is aligned with the insert part recess 38. [0030] The inner wall of the first profile of support edge 14.1 and of the second support edge profile 14.2 have two recesses of support edge profile 46 that are aligned with the corner connector recesses 42 of the corner connection unit 18 when the first or second arm 20.1, 20.2 is inserted in cavity 16.1 or 16.2, respectively. [0031] Finally, between the two recesses of the support edge profile 46 of the support edge profiles

14.1 and 14.2 a respective profile connection recess 48 is provided which, when the first or second arm 20.1, 20.2 of the corner connection unit 18 is inserted, is aligned with the arm connection recess 44 of these. [0032] In the production process of the floor covering device 10, firstly the insert 32 is inserted levelly into the first transverse recess 30.1 / second transverse recess 30.2 of the first arm 20.1 / second arm 20.2 of the unit of corner connection 18. Next, the first arm 20.1 or the second arm 20.2 is inserted into the first cavity 16.1 or the second cavity 16.2, respectively, of the

first support edge profile 14.1 or the second support edge profile 14.2, respectively. In this situation, the insert piece recess 38 is respectively aligned with the arm connection recess 44 and the profile connection recess 48. Through these recesses 38, 44, 48 the second connection means 28 are fixed, which are respectively configured as a rivet. In this situation, the corner connection unit 18 is fixed to the first support edge profile 14.1 or to the second support edge profile.

14.2. The thread of the nuts of the complementary connection means can be accessed respectively from the outside of the support edge profile notch 46 and the corner connector notches 42

26. [0033] Next, in the corner area, a snap-in housing unit 22 can be connected whose outer walls, which are oriented towards the first support edge profile 14.1 or the second support edge profile 14.2, they are arranged at right angles and have front end surfaces 40.1, 40.2, 40.3,

40.4 (see Figure 7) which are supported at least by areas in the inner wall of the first support edge profile

14.1 or the second support edge profile 14.2, respectively. The geometry of these supported outer walls has the same configuration respectively. [0034] The outer walls respectively have two connection recesses 52 which, when the nesting leg housing unit 22 is placed, are aligned with the support edge profile recesses 46 and the arm connection recesses 44, which it allows the first connection means 24 configured as screws to be connected to establish the connection with the complementary connection means 26 of the corresponding insert 32. Thus, if necessary, the nesting leg housing unit 22 can be mounted simply, quickly and reliably in the corner area, in particular allowing the solid insert 32 to obtain high rigidity and load capacity also with Small wall thicknesses of the first support edge profile 14.1 or the second support edge profile 14.2. [0035] The nesting leg housing unit 22 has a housing opening 64 open downwards, into which the nesting leg profile 50 can be inserted. Inside the housing opening 64, in the area next to the corner of the floor covering, a respective fixing projection 60 protrudes on which the wedge profile 50 is supported by the outer face. [0036] In the opposite corner of the nestable leg housing unit 22 there is formed an essentially U-shaped housing boss 62, within which a pressure piece surface unit 36 is disposed inwardly movable way. On the outside, the pressure piece surface unit 36 is subjected to the action of a fixing screw unit 34, that is, by actuating the fixing screw unit 34 the pressure piece surface unit 36 is it moves inwards or outwards, depending on the direction of rotation, and therefore fixed under pressure or releases the inserted leg profile 50 introduced. The housing projections 62 or the pressure piece surface unit 36 are configured with respect to their bearing geometry with the fittable leg profile 50 such that it is possible to introduce and imprison both a leg cross-section profile Square fitting as a cross-sectional profile of round fitting leg. [0037] The two outer walls which, when the nesting leg housing unit 22 is placed, are oriented towards the first support profile 14.1 or the second support profile 14.2 have the same geometric structure (see, for example, figure 7). [0038] In Figure 7, one of these outer walls is oriented towards the observer and another is oriented to the left, the nesting leg housing unit 22 being shown in Figure 7 in a view from below. In the lower area of the nesting leg housing unit 20, two first L-shaped shoulder units 54 are disposed apart, respectively having a front end surface respectively

40.1 in which the connection recess 52 is located. Above the first shoulder unit 54 there is a respective second shoulder unit 56 with the front end surface 40.3. Between the first projection unit 54 and the front end surface 40.3 of the second projection unit 56 is an incoming front end surface 40.2. Above the second shoulder unit 56 is an incoming front end surface 40.4. [0039] As can be seen in Figure 3, when the nesting leg housing unit 22 is placed, the front end surfaces 40.1, 40.2 and 40.4 rest on the outer wall, which is present on the inside, of the First support profile unit 14.1. As shown in FIG. 4, when the snap-in housing unit 22 is positioned, the front faces 40.1, 40.2 and the bottom face of the second shoulder unit 56 rest on the outer wall, which is present in the inner part, of the second support edge profile 14.2. [0040] As can be seen in Figure 7, a screw recess 58 is provided in the lower area of the wall face facing the observer, which is aligned with the connection recess 52 present in the first left shoulder unit 54 This allows access to said connection recess 52 from the outside with a screwdriver. The same applies to the other adjacent wall face. As can be seen in Figure 1, the connection recess 52 located on the right in Figure 7 is accessible from the outside with a screwdriver directly from its rear. [0041] By means of the chosen geometry of the first shoulder unit 54 and the second shoulder unit 56 in relation to the front end surfaces 40.1, 40.2, 40.3, 40.4 sufficient support surface is available for the support in the outer wall facing towards inside both the first support edge profile 14.1 and the second support edge profile 14.2, so that, also in the case of a relatively thin wall thickness of the support edge profiles 14.1, 14.2 together with the insert 32 as a solid profile used in the corner connection unit 18,

[0042] there is a joint that ensures high rigidity and at the same time a high load capacity. At the same time, there is a very simple connection in terms of the mounting technique, of a housing unit that can be fitted in a floor covering device 10, which if necessary can be quickly mounted or disassembled.

[0043] In Figure 1, a corner-shaped unit 66, which can be released releasably and completes the chamfered corner of the floor covering 12, is shown in a complementary manner underneath the nesting leg housing unit 12. or the entire corner area to form a 90º corner. Preferably, the corner unit 66 is made of plastic. In addition, in Fig. 1, a cover unit 68 is shown above the pressure piece surface unit 36 by which the unit

10 of the pressure piece surface 36 inserted in the nesting leg housing unit 22 is secured in its mounting position when the fixing screw unit 34 does not exist, and which at the same time constitutes a protection against dirt.
