Description

Connection system for a mobile floor

The invention relates to a connection system for a mobile floor with a

Variety of rectangular in plan view plates, which are connectable at their longitudinal edges with adjacent plates, wherein the plates form a common surface and for connecting two longitudinally adjacent plates in each case a Nutstück and a spring piece in the longitudinal edges of the adjacent plates are arranged and the Nutstück and the spring piece made of a dimensionally stable material.

From DE 203 07 074.7 a connection system for floors is already known in which two adjacent plates are pivotable into one another along their longitudinal edges, so that they are held in a horizontal adjacent position substantially form-fitting manner to each other. There are a number of such connection systems and these can both be machined from the material of the plate or formed by metallic elements. A disadvantage of the aforementioned systems is that they can be assembled and disassembled only with considerable time and therefore also cost expenditure.

Object of the present invention is therefore to provide a connection system for mobile floors, which is easy to install.

This object is achieved with a connection system for mobile floors with the

Characteristics of claim 1 solved.

According to the invention, the groove piece has a web surrounded by the plate material, a groove adjoining the latter, the opening of which narrows from its closed side to the open side, and a tongue adjoining the lower edge of the groove and the spring piece one of which Plate surrounding web, an obliquely upward away from the web spring, and has a rail which protrudes from the rear region of the spring upwards. This makes it easy to disassemble or assemble the floorplate. secured along their long sides and the plates are stably held together.

According to a preferred embodiment, the tongue of the Nutstücks a trough and the spring on its underside a bulge, which engage in a form-fitting manner, so that a joint is formed. As a result, a special simple and, in cooperation with the obliquely upwardly extending spring, secure locking of the Nutstücks causes the spring piece.

For fixing the Nutstücks and the spring piece provided in the bottom plate columns preferably the web of the Nutstücks and / or the web of the spring piece are glued in the longitudinal edges of the plates. In order to achieve a particularly good distribution of the adhesive along the groove and / or spring bars, there are preferably one or more grooves in the web of the Nutstücks and / or in the web of the spring piece, which are preferably parallel to the longitudinal edge of the bottom plate.

To ensure a special strength and durability consists of the groove piece and / or the spring piece made of metal. To connect permanently adjacent plates without gaps, forming a front edge of an upper

Nutschenkels together with an end edge of the rail of the spring piece a stop.

Due to the geometric shape of the Nutstücks and the spring piece they are already separated at an angle of 5 ° to 25 °, in an even more preferred embodiment at an angle of 10 ° to 20 ° apart, which in particular a quick installation and rapid disassembly of the mobile Soil allows.

It is also advantageous that the longitudinal edges of the plates in a frontal

Notching the plates are supported by a relining of the plate surface material with the groove piece or the spring piece. This prevents the breaking off of a cover layer, in particular of the particularly stressed panel corners. Furthermore, the flexibility of the soil is increased in a large-scale curvature due to a load that in the assembled state of Nutstück and spring piece, an upper side of the spring rests against the upper groove leg and between a lower groove leg and the spring a hollow space is formed, the closes to the hollow. This tolerance compensation is possible because the spring can bend slightly downwards.

According to a further embodiment, the end faces of adjacent plates are defined by a web fixed to and protruding from the first plate, from the protruding piece of which a mandrel protrudes upwardly into a groove

Receiving the adjacent plate engages, connectable to each other to produce a positive end-side connection between the plates.

The invention will be explained in more detail below using an exemplary embodiment with reference to the drawings. Show it:

Figure 1 is a plan view of a floor with a erfmdungsgemäßen connection system;

Figure 2 is a sectional detail view through two longitudinal edges of two adjacent plates of Figure 1;

Figure 3 is a sectional detail view of a Nutstücks invention;

Figure 4 is a sectional detail view of a spring piece according to the invention;

Figure 5 is a sectional detail view through two end edges of two adjacent plates of Figure 1, and

Figure 6 is a sectional side view through two longitudinal edges of two adjacent plates according to a modified embodiment.

A bottom is formed by a multiplicity of adjacently arranged plates 1 which are in each case arranged on opposite longitudinal edges and opposite end faces. edges are connected. The plates arranged at the edge can either be surrounded by a frame towards the outside or have a corresponding termination, since there no connection to an adjacent plate has to be made.

An embodiment of the connection system at the longitudinal edges is shown in Figures 2 to 4 in section. On one of the longitudinal edges of a metal, in particular aluminum, existing groove piece 2 is arranged, which engages with a web 21 in the plate 1 and is glued there. In this groove piece engages in the opposite plate 1 made of metal, in particular aluminum, existing spring piece 3, wherein the spring piece 3 engages with a web 31 in the plate 1 and is glued there. In the mounted state, the plates 1 lie next to one another in a horizontal plane and form a surface. The connection system is not visible from the outside and the spring piece 3 engages in the groove piece 2 a. The groove piece 2 has, in addition to the web 21, a groove 22 adjoining it, the opening of which narrows from its closed side to the open side. At the bottom of the groove, a tongue 23 connects, which has a rounded trough 24. The spring piece has, in addition to the above-mentioned web 31, a spring 32 running obliquely upward away from the web 31, which engages behind the groove 22 narrowing from its closed side toward the open side. At the rear lower side of the spring 32, a bulge 34 is formed, which engages with the trough 24 of the Nutstücks 2 form-fitting manner. In the assembled state of Nutstück 2 and spring piece 3 is an upper side of the spring 32 of the lower side of an upper groove leg 26 and between a lower groove leg 27 and the spring 32, a cavity 28 is formed, which extends to

Mulde 24 closes. The groove leg 26 widened towards the end side, so that the groove widens wedge-shaped. As a result, a tolerance space for loads of the plates 1 is given, in which the plates 1 can be pushed down.

Due to the geometry of groove 2 and spring piece 3, the groove 2 and spring piece 3 are separable from each other in a very favorable for the construction and dismantling angle range of 5 ° to 25 ° and yet provide in the assembled state a secure cohesion against pulling in horizontal direction. In a special embodiment, these are even in an angular range of 10 ° to 20 ° separable from each other. In addition, the longitudinal edges of the plates 1 are supported in a face-side notching of the plates by a relining of the plate surface material with the groove piece 2 and the spring piece 3. As a result, in particular the corner regions of the plates are protected against breakage. From the rear region of the spring, a rail 33 protrudes upward, which forms a stable stop together with an end edge of an upper groove leg. The webs of tongue and groove piece are provided with grooves 25, 35 in order to ensure a uniform distribution of an adhesive along the webs.

In Figure 5, the connection of two end edges of adjacent plates 1 is shown. On a plate 1, an existing metal web 4 is fixed, which protrudes beyond the front edge of the plate 1. On the protruding part of the land 4, an upward-facing mandrel 5 having a frusto-conical portion 51 is formed in the upper portion thereof. The mandrel 5 is arranged in a receptacle 6, which is formed from a hood-shaped plastic part, which is enclosed by means of teeth in the material of the plate. To prevent damage to the wood material by the mandrel, the receptacle is covered by a cover layer 61. The formation of a gap between the end edges of adjacent plates is prevented by the positive retention of the dome 5 in the receptacle 6.

Upon the occurrence of a tensile load of the mandrel 5 presses against the receptacle 6, whereby a sliding apart of the plates 1 is prevented. The receptacle 6 causes the existing of wood material plate 1 does not tear. A spring 7, which is inserted in equal shares in a groove on the end edges of the adjacent plates 1 and extends substantially over the entire length of the end edges, prevents rotation of the plates 1 in the region of the end edges. The strip-shaped spring 7 is tapered wedge-shaped towards the end, so that it is clamped in the groove can be fixed, which may be at least partially also wedge-shaped. The web 4 is positioned on the opposite plate with a centering pin 8 and shown schematically

Screwed 9 screwed to the plate 1. The centering pin 8 is held in a bore in the plate 1. FIG. 6 shows a slightly modified embodiment of a connection system with a strip-shaped groove piece T and spring piece 3 '. The groove piece 2 'comprises a lower, longer leg 27 and an upper, shorter leg 26, which has a chamfer 29 at the bottom end. As a result, between an obliquely upwardly projecting spring 32, the upward

Rail 33 and the upper leg 26, a cavity 30 is formed, which simplifies the mounting and dismounting of the connection system. Because at an angle between 5 ° and 15 °, preferably about 10 ° relative to the horizontal obliquely upward spring 32 can through the cavity 30 and the cavity 28 between the spring 32 and the lower leg 27, the spring

Although 32 lie in the installed state on the oblique bottom of the leg 26 and provide a lock, but pivoted to disassemble in a simple manner and be removed from the groove piece 2 '.

The plates 1 are glued on their underside with a layer of foam 10, which may be covered on the bottom side with a nonwoven material. Instead of the foam may also be provided a foamed plastic, if a lower elasticity is desired. As a result, the plates 1 can be laid on a hard surface and still have the elasticity required for sporting events.
