DE8609370U1 - Transition profile for bridging joints or seams in floor coverings - Google Patents

Description

The innovation relates to a transition profile consisting of a curved rail that can be connected to the floor for bridging of joints or seams in floor coverings.

When laying floor coverings, e.g. carpet, needle felt, PVC or linoleum, a joint or seam is created there, where two, mostly different, coverings are laid against one another; this is usually the case in the door area.

To bypass such a seam, the shape of a crescent has hitherto been used curved transition profiles, so-called. Curved rails, e.g. made of brass, aluminum or stainless steel, are used, whereby the Material thickness of such rails is between 0.8 and 1.25 mm. When laying such arched rails, the following arise, among others

Disadvantages, Since the curved surface is perfectly smooth, there is a risk of slipping, which is increased by the curvature. Especially with the most frequently misplaced Curved rails with a thickness of approx. 0.98 - 1.1 mm will be the Curvature flattened at the points where a screw connection takes place. This usually happens when wood screws are in the can be screwed into the bores provided in the vaulted rails * However, as soon as the screws are tightened, it gives way at this point, the relatively thin material downwards so that the arched rail is flattened in this area. After five screw connections are usually provided per 1 m, the will continue to be carried out at regular intervals occurring flattening increases the risk of slipping mentioned above.

Finally, it should be noted that the screw head of the countersunk wood screws due to an imperfect position not lie clean or flush in the recesses, but - to a limited extent due to the screw bolt wandering to the side - may lie at an angle. The resulting, not from sinking The protected screw head edge is sharp-edged, which creates a risk of injury to the person using the Cleaning or wiping carpets or the arched rail.

The innovation is based on the task of creating a transition profile | of the type mentioned at the beginning / which is not only dimensionally stable, but also reduces the risk of slipping.

This object is achieved in that according to the innovation Rail in the middle section a support surface parallel to the floor and having curved edge sections proceeding therefrom on its underside, and that at least the edge sections are provided with a non-slip surface. Through the

The transition profile receives a larger flat contact surface Stability, while the anti-slip surface reduces the risk of slipping.

According to a particularly preferred embodiment of the innovation, the surface of the middle section runs parallel to the support surface and, in the installed state, has an anti-skid insert that runs flush with the edge sections. Through this This not only avoids the risk of injury from screw head edges, but also a "flexible" middle section of the transition profile.

The middle section can have countersunk drill holes for receiving countersunk head screws. It is assumed here that the The transition profile is to be fastened using conventional fastening means, namely screws; in this context It should be mentioned that other types of fastening of the arched rail, e.g. by means of nails, are of course also possible.

It has been found to be particularly useful if the anti-skid insert has a self-adhesive layer on the underside is provided. This anti-skid insert, known per se, can be provided with a removable protective film on the adhesive side so that it is easy to use and relocate the anti-skid insert results. This anti-skid insert not only has a slip-resistant effect, but also conceals it the heads of the fasteners, especially any countersunk wood screws and increases the optical decorative effect of the transition profile. In this context it can be mentioned that the anti-skid insert can, for example, be differentiated in color from the transition profile. The surface of the anti-skid insert can e.g. be black, brown or beige, while the rest of the transition profile - if it is made of metal - is single

% loan can be polished; also an anodization in gold> silver

g or bronze is possible.

'! The anti-slip surface expediently consists of

corrugations, grooves or the like running in the longitudinal direction of the rail. As already mentioned, this surface is non-slip

f intended only in the edge sections.

It has already been mentioned that the rail is made of metal,

preferably brass or aluminum or made of plastic

can exist.

The above-mentioned anti-skid insert is expediently flexible and can be made of plastic.

The construction of the transition profile according to the innovation is - as already noted - particularly stable, with the rail almost twice as thick in the middle section -> ie in the edge sections can be.

In the drawing, an example embodiment of the innovation is shown; it is described in more detail below. It shows:

1 shows a section through the transition profile to be laid on a floor covering seam point and

Fig. 2 is an oblique view of the same embodiment.

A transition profile 1, e.g. 33 mm wide, consists of silver anodized Aluminum and has the cross section shown in FIG. 1. A needle felt 3 is on a wooden floor 2 and another type of carpet covering 4 is applied, e.g.

sticks, with a joint or seam between the two coverings 5 arises, which is covered with the transition profile 1 and bridged.

The transition profile has a central section 6 a width of e.g. 10 mm, with edge sections 7 and 8 adjoining each.

The lower surface 9 of the middle section 6 is almost at the level of the support edge 10, 11 of the respective edge sections 7 or 8, whereby to increase the sealing effect of the transition profile, a height difference of approx. 1 mm between the lower edge 10, 11 and the lower surface 9 can be provided. The surface 12 of the central section runs parallel to the lower surface 9, wherein the latter is each bordered by edge surfaces 13, 14 projecting perpendicularly therefrom.

The edge portions 7 and 8 are provided with corrugations 15, which are provided to prevent the risk of slipping and in Run in the longitudinal direction of the transition profile. These corrugations can be made in any way; In the present embodiment, the corrugations have a cross-section which consists of a zigzag band with right angles fj results. f

As can be seen in particular from FIG. 2, are in the middle section Countersunk drill holes 20 with conical edges 21 are provided, which are used to take on countersunk wood screws 22. The bottom edge 23 of the screw head 24 has a shape corresponding to the countersunk boreholes 20.

After the wood screws 22 have been screwed in, an anti-skid film 30 is inserted into the central section 6. This anti-skid

Foil 30 has a protective foil 31 to simplify transport, which is peeled off shortly before use, so that a self-adhesive layer 32 is released.

As can be seen in particular from FIG. 2, the corrugations 15 are not on the entire surface of the edge sections 7 and 8 provided, but only in their central area; Thus, on both sides of this central area, there are unfluted edge areas 40 and 41 provided. The edge area 41 merges into the edge 13.

It should also be mentioned, - that the lower surfaces 42, 43 of the edge sections 8, 7 are arched, while the immediate contact surface 10 or 11 of the edge sections on the floor coverings 3 or 4 runs flat over a narrow area.

Due to the tolerance of 1 mm between the lower surface 9 of the central section and the contact ends 10, 11 of the edge sections an adaptation to the mostly highly flexible surfaces of the floor coverings, e.g. made of needle felt, is achieved.

While the middle section is 2.2 mm thick, the thinnest points in the edge area are only 1.0 mm thick. Except for the ones listed above Materials can also be metal alloys, e.g. an aluminum alloy Al Mg Si 0.5, preferably in strength "F 22".

In the final installed state, the corrugated edge sections 7 and 8, in cooperation with the anti-skid film 30 (in the middle section 6) an optimal non-slip and safe surface of the transition profile.
