Abstract

The invention concerns a threshold bar comprising a base section (20) to be fixed on the floor and a covering section (25) to be fixed with screws (27) on the base section. The covering section comprises a longitudinal tongue (24) with a thickened end part (29), and holes (24) for passing through the screws along an axis parallel to the tongue (24) and offset relative thereto. The base section comprises two longitudinal juxtaposed parallel grooves (21, 22) designed to receive the tongue (24) and the screws (27) passing through the covering section passage holes. The tongue is dimensioned with respect to the groove designed to receive it so as to be able to pivot about a longitudinal axis.

Description

LBV~ CO~~TSATI~T ~ BII~i The present invention relates to an edge binder, that is, an element intended for hiding a joint between two floor coverings or for forming a clear border between a floor covering and a wall. The present invention more specifically relates to an edge binder adaptable to various covering heights and enabling ca~pensation of the height difference between two floor coverings.
Fig. 1 shows a cross-section view of a conventional edge binder of this type, described in European patent application 0,321,634. This edge binder includes an L-shaped base profile strip 10 including a horizontal portion attached to floor 12 and a vertical portion 10-1 intended for fastening a covering profile strip 14. The vertical portion 10-1 of the base profile strip is thick and includes screw holes 16 regularly spaced apart intended for fastening the covering profile strip 14 with screws.
Covering profile strip 14 includes two vertical tongues 14-1 that bear on either side of vertical portion 10-1 of the base profile strip. Covering profile strip 14 further includes two slanted flaps 14-2 and 14-3, extending downward on either side of the upper surface of tongues 14-1. One of slanted flaps 14-2 is intended for bearing, as shown, on a thick floor covering 18, while the other slanted flap 14-3 is intended for bearing on a thin floor covering.
A disadvantage of this edge binder is that it is provided to canpensate a specific level difference between floor coverings. A slight variation of the level difference is allowed by a certain flexibility provided to the slanted flaps of the covering profile strip, enabling their deforn~ation. Indeed, these flaps are connected to the central portion of the profile strip by thinned areas 19. But this solution is insufficient to enable compensating a wide range of level differences.
German utility model 29,711,389 describes a system ccx~lementary to that shown in Fig. 1, in which, instead of having two vertical tongues of the covering profile strip bearing on either side of the vertical portion of the base profile strip, a vertical tongue of the covering profile strip inserts into a groove of a base profile strip. Again, this system only enables compensation of a slight level difference, by twisting the flaps of the covering profile strip by taking advantage of the existence of thinned areas.
An object of the present invention is to provide an edge binder enabling compensation of a wide range of level differences while ensuring a high resistance against lateral ef fort .
These objects are achieved by means of an edge binder including a base profile strip to be attached to the floor and a covering profile strip to be attached by screws to the base profile strip, in which the covering profile strip includes a longitudinal tongue, and screw holes along an axis parallel to the tongue; and the base profile strip includes two longitudinal parallel and adjacent grooves, a first one being intended for receiving the tongue and the second one being intended for receiving screws crossing the holes of the covering profile strip. The tongue is sized with respect to the groove intended for receiving it so as to be able to pivot around a longitudinal axis.
According to an embodiment of the present invention, the tongue ends by a thickened portion and the first groove has a width substantially equal to the width of the thickened portion of the tongue.
According to an embodiment of the present invention, the walls of the second groove are longitudinally corrugated substantially at the thread pitch of the screws for fastening the covering profile strip.
According to an embodiment of the present invention, the grooves (31, 32) have the same configuration, so that the covering profile strip can be turned over.
According to an embodiment of the present invention, the walls of the two grooves are langitudinally corrugated substantially at the thread pitch of the screws for fastening the covering profile strip, and said tongue is corrugated at the same pitch, the maximum width of the tongue being smaller than the minimoum width of a groove.
According to an embodiment of the present invention, the tongue continuously extends along the length of the covering profile strip.
The foregoing objects, features and advantages of the present invention will be discussed in detail in the following non-limiting description of specific embodiments in connection with the accompanying drawings.
Fig. 1, previously described, shows a conventional edge binder;
Fig. 2 shows an embodiment of an edge binder according to the present invention; and Figs. 3A and 3B show a reversible covering profile strip according to a second embodiment of the present invention.
An edge binder according to the present invention enables compensating a wide range of level differences due to the fact that its covering profile strip has a certain freedom of rotation around a langitudinal axis while having a vertical 3 5 freedom of mot ian .
In Fig. 2, an edge binder according to the present invention includes a base profile strip 20 including two parallel juxtaposed vertical grooves 21 and 22. One of the grooves, 21, is intended for receiving a vertical tongue 24 of a covering profile strip 25. The other groove, 22, is intended for receiving screws 27 for fastening covering strip 25 to base 20. For this purpose, covering strip 25 includes holes 28 regularly spaced apart longitudinally, in correspondence with groove 22. As shown, to improve the reliability of the screw fastening, the walls of groove 22 are longitudinally corrugated substantially at the thread pitch of screws 27.
According to a significant aspect of this embodiment of the present invention, the lower portion of tongue 24 includes a thickened portion 29, for example cylindrical, of a width substantially equal to the width of groove 21. With this configu-ration, tongue 24, and thus covering strip 25, can rotate on either side of the center of thickened portion 29 until a wall of tongue 24 contacts an upper edge of groove 21. This freedan of rotation enables covering strip 25 to adapt to a range of level differences between floor coverings, this range being all the wider as the position of thickened portion 29 in groove 21 is high.
Normally, when screws 27 are tightened, the lateral edges of covering strip 25 contact their respective floor coverings and tongue 24 sinks by a corresponding amount into groove 21. Then, any lateral effort exerted an crnrering strip 25 is transmitted fran tongue 24 to one of the walls of groove 21 via thickened portion 29, which relieves screws 27 from lateral efforts. Indeed, screw fastenings poorly withstand lateral efforts due, for example, to kicks on the edge binder, trolley crossings or motions of furniture. This is why in the conven tional edge binder of Fig. 1, no clearance is present between tongues 14-1 and vertical portion 10-1 of the base profile strip, this absence of any clearance preventing any rotation of the covering profile strip.

To obtain a maximum rigidity of tongue 24, and thus to optimize its ability to transmit lateral efforts, this tongue is preferably continuous and extends along the entire length of the edge binder.
5 Despite the freedan of rotation of covering strip 25, an edge binder according to the present irnrention does not enable compensating all level differences in all cases. To widen the range of ccxnpensable level differences, covering strips of different shapes are provided.
As an example, Fig. 2 shows a flat covering strip 26 enabling compensating level differences between floor coverings having substantially the sate thiclaiess.
when the covering strip is asymmetrical, it is inter esting to be able to turn it over, by inserting the tongue into any one of the grooves and the screws into the other. This enables positioning the covering profile strip independently from the initial position of base 20. Then, groove 21 will have the same configuration as groove 22 and will preferably be corrugated .
Figs. 3A and 3B show such an embodiment for two heights of a floor covering 18. A base strip 30 includes two parallel juxtaposed vertical grooves 31 and 32. The two grooves are longi-tudinally ribbed. In the shown assembly, groove 32 receives a vertical tongue 34 of a covering strip 35 including two flaps 35-1 and 35-2. The border of flap 35-1 bears against covering 18 and the border of flap 35-2 bears against the floor. Tongue 34 is ribbed. The greatest width of the tongue, after grooving, is smaller than the minimum width defined by the protruding portions of the grooves . T'hus, for example, if the smallest width of the grooves is on the order of 2.6 mm, the greatest width of the tongue will be on the order of 2.4 mm. Thus, the covering strip can be inserted substantially vertically into a groove and can pass from the position shown in Fig. 3A to the slanted position shown in Fig. 3B. It should however be noted that the representa-tion of Fig. 3B is very simplified. Each screw hole 38 will preferably be oblong so that the screw can continue vertically inserting into the underlying grove and, once the screw is engaged, the tongue will be in abutment by at least two points~of its opposite sides against the corresponding groove, to ensure the rigidity function and the above-mentioned aptitude to transmit lateral efforts.
As shown, the covering profile strip preferably exhibits an overthiclmess at the locations where the possibly oblong screw insertion holes are formed.
The present invention is likely to have various alter-natives which will appear to those skilled in the art. In particular, the covering profile strip may have various shapes, for example usual shapes adapted to satisfying the usual functions of formation of a joint between coverings of variable and/or different heights, and to form a lateral joint between the limit of a covering and a wall.
Further, as shown, covering profile strips 25 and 35 of Figs. 2 and 3 are slightly hollowed at their upper surface level, which enables applying on these profile strips decorative or antiskid adhesive strips having their edges protected by shoulders.
