DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a band-shaped device for forming a pipe-shaped protection cover for telephone and electrical cables and the like.
DESCRIPTION OF PRIOR ART
Previously known devices for forming a cover for electrical cables and the like have for different reasons not given rise to any need on the industrial market for which reason they are difficult to obtain if not completely impossible to have at hand. One of the main reasons is that the known constructions are difficult to manufacture and thus involve high production costs resulting in a high selling price. Furthermore, many known constructions intervene in existing installations which in turn implies high installation costs and frequently demands that the installation is carried out by a professional. These factors also give rise to a high expense for the known products.
SUMMARY OF THE INVENTION
One object of the present invention is to improve known devices so that they will be cheaper to manufacture and distribute and simpler to install.
According to the present invention these problems are solved by means of the device mentioned in the introduction by the fact that at least one surface of a band is provided with angular grooves, whose appices are placed near the opposite side of the band and whose opposite edges extend above the surface of said one surface, and that locking means, intended to cooperate with each other, are provided at the longitudinal side edges of the band, the angular grooves extending in parallel with the side edges.
The present invention enables manufacturing by means of extrusion of a suitable plastic material in a simple tool. Furthermore, sale of the product in a very simple package is made possible, since the profiling of one side of the band renders the manufacture of the band possible in a soft material without sacrificing the high demands for stiffness of the ready-made cover. The design of the arrangement according to the present invention also renders a very simple application of it possible in existing installations, for example, on top of an existing skirting or the like.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 shows, on enlarged scale, a side view of one embodiment of a device according to the present invention.
FIG. 2 is a side view of the device shown in FIG. 1 after forming is as a cover.
FIG. 3 is a schematic perspective view of an installation with a device according to FIGS. 1 and 2.
DETAILED DESCRIPTION
The device shown in the drawings according to the present invention is manufactured as a band 1 (FIG. 1) having one surface which is plain and whose other surface is profiled and has three angular grooves 2, 3, 4 and a male-shaped snap-lock element 5 at one of the edges and a female-shaped snap-lock element 6 at the other edge. Each apex of the angular grooves 2, 3 and 4 is located near the plain surface of the band 1 and since the band is made of a soft plastic material the material part at the apex can be considered to form a thin hinge. The sides of the angular grooves 2, 3 and 4 extend above the surface of the band 1 in which the grooves are formed and form elevations on each side of the angular grooves 2, 3 and 4. In the present embodiment of the invention, the angle between the sides in the angular grooves 2, 3 and 4 is approximately 90.degree..
The male-shaped snap-lock element 5 has a conventional design and is placed inwards of the slightly bevelled side edge of the band 1, while the female-shaped snap-lock element 6 is arranged in the other side edge of the band 1.
It will furthermore be pointed out that the angular grooves 2, 3 and 4 extend parallel to the longitudinal side edges of the band 1.
In order to form a pipe-shaped protection cover of the device as described above according to the present invention, the band 1 is folded for closing the angular grooves 2, 3 and 4 as will be described more in detail in FIG. 2 and the male-shaped snap-lock element 5 is snapped into the female-shaped shap-lock element 6. As it appears from FIG. 2, the sides in
