Abstract

This cable bushing can be made to be in a closed state or an opened state, in a simple manner, depending on the use. Its insertion part (1) consists of two halves (2, 3) which are completely separate and are inserted loosely into the cut-out (4) in the baseplate (5). A plurality of incisions (7, 8) having an obliquely positioned bottom (7.1, 8.1) are provided on both halves in order to pass the cables (9) through, which incisions (7, 8) in each case start on first covering surfaces (2.1, 3.1) of the halves (2, 3) and end on mutually adjacent side surfaces (2.2, 3.2) which run at right angles thereto. When the cable bushing is unused, the halves (2, 3) are inserted into the cutout (4) in such a manner that second covering surfaces (2.3, 3.3) of the two halves rest flush with respect to the top (5.1) of the baseplate (5). When the cable bushing is in use, the halves (2, 3) are inserted into the cutout (4) such that the first covering surface of the one half and the second covering surface of the other half are located at the top. In the case of this arrangement, continuous guide channels are formed for the cables, which guide channels are composed of the incisions (7, 8) in both halves (2, 3). <IMAGE>

description

The invention relates to a cable bushing for raised floor panels, with a disk-shaped insert intended for insertion into a cutout of a base panel, which is divided into two adjacent halves which touch one another on two side surfaces running perpendicular to the top surfaces and openings for openings to be carried out on these side surfaces Form cables.

In the case of raised floors, which are mainly installed in office, administration, industrial and commercial buildings, various types of cables, such as for the power supply, telephone, control and data connections for EDP, etc., Are located in the cavity under the floor slabs forming the walkable floor . relocated. The cables are connected in many places to junction boxes mounted in the cavity, in which cables from devices or other devices can be connected via sockets, which are stationed in the room above the floor plates. These cables run through cable glands that are installed in individual base plates as required. Such bushings are often not or not fully occupied with cables, but are installed on reserve for later extensions. They must allow the cables to be easily replaced and their plugs pulled through.

A known cable bushing of the type mentioned consists of an outer ring and a disc-shaped insert made of plastic held therein. The two halves of the latter are laterally connected to one another in a hinge-like manner, with vertical holes being provided for the passage of the cables, half of which lie in one and in the other of the contacting side surfaces of the insert halves. If a cable is to be pulled through, the insert part is removed from the outer ring and opened, and closed again after the cable has been inserted and inserted into the outer ring. This handling is cumbersome, especially when several cables have to be inserted into the half-holes at the same time. When leaving the vertical holes, there is a risk that the cables will be kinked and damaged. In addition, this cable entry is relatively complicated and correspondingly expensive to manufacture. If the cable bushings are not used or not fully occupied, their holes are openly accessible, which is unsightly and promotes the accumulation of dust and dirt. The color of this cable entry cannot be adapted to the respective floor covering and it visually represents a foreign body.

The invention is based on the object of proposing a cable bushing of the type mentioned at the outset, which is of simpler construction and therefore cheaper, is easy to handle and also does not have the other disadvantages mentioned.

This object is achieved by the invention characterized in claim 1. Here, on the two identical halves of the insert, there are several channel-like incisions with a bottom that runs obliquely to the cover surfaces. These incisions each begin on one top surface and end on the side surface. Both halves are completely separated from each other and can be placed in the cutout of the base plate in the same or opposite position, depending on the type of use. Inserted in the same position, i.e. If the passage is (still) unused, the second cover surfaces of both halves together form a flush, closed surface. If, on the other hand, the halves are inserted in opposite directions to one another, their incisions overlap on the contacting side faces and together form continuous cable routing channels.

An advantage achieved with the invention is to be seen in the fact that only a single, very easy-to-produce molded part is required for the cable leadthrough (two identical parts in each case). Another advantage is that as long as the implementation is undeflected, i.e. is installed in reserve, the parts are inserted into the cutout of the base plate in such a way that there is a closed surface without openings or air passage that does not require additional cover. By simply turning one half, the cable routing channels inclined to the floor surface are formed, from which the cables emerge without risk of kinking; By rotating the insert in the cutout, the exit direction can also be selected at any time. The parts can also be provided on both sides with the same floor covering with which the floor plate is covered, in which the bushing is installed. The implementation is then hardly visible in the closed state and is practically not noticeable even when in use.

The invention is explained in more detail below using an exemplary embodiment in conjunction with the drawing. Show it:

Fig. 2 shows a cross section of the cable entry used in a base plate in the closed state when not in use, and

Fig. 3 shows an analog cross section of the cable bushing when used with a cable.

1 to 3, 1 denotes a disk-shaped insert which is composed of two identical halves 2, 3. The insert 1 is inserted into a cutout 4 (stepped bore) of a base plate 5 of a double floor, not shown. The insert 1 is supported on a shoulder 6 in the cutout 4, being flush with the top 5.1 of the base plate 5. 7 and 8 are channel-like incisions for cables 9 to be carried out; in each half 2, 3 there are several (e.g. six) such cuts 7 and 8 parallel to each other. They start at the first cover areas 2.1, 3.1 of the half

ten 2, 3 and end on perpendicular side surfaces 2.2, 3.2 of the halves 2, 3 where the two halves touch. The incisions 7, 8 preferably have a semicircular base 7.1 or 8.1, which extends at an oblique angle to the top surfaces (and to the side surfaces). On the side surfaces 2.2, 3.2. the incisions 7, 8 are deeper than half the thickness of the insert 1.

The halves 2, 3 of the insert 1 are preferably made of a suitable plastic. To pass through thicker cables 9, partitions 10, 11 between the incisions 7, 8 can be removed as required during assembly. Both halves 2, 3 are completely separate. They can therefore be easily lifted out of the cutout 4 or inserted in one or the other position (with one or the other top surface facing up).

If no cables 9 are to be laid, both halves 2, 3 with the first cover surfaces 2.1, 3.1 rest on the shoulder 6, the second cover surfaces 2.3, 3.3 of both halves being flush with the top 5.1 of the base plate 5 and the cuts 7,

8 are not visible (Fig. 2). Then when the implementation is put into use, i.e. electric wire

9 must be pulled through, then one half (for example half 2) is turned through 180 °, so that it rests with the second cover surface 2.3 on the shoulder 6 and its first cover surface 2.1 with the top 5.1 and with the cover surface 3.3 of the other half 3 is flush. In this case, continuous guide channels for the cables 9 are formed from the incisions 7, 8 of both halves, in that the above-mentioned incisions overlap in height on the side surfaces 2.2, 3.2 (FIG. 3). The edges of the incisions 7, 8 are expediently rounded (not shown) at the transitions to the top surface and the side surface.

Instead of the circular shape of the insert 1 assumed in the exemplary embodiment, other, for example square, rectangular or oval shapes with corresponding base plate cutouts are also possible. Likewise, instead of the six notches shown for the cables, a different number can of course be chosen, the width and the shape of the base can vary. It is expedient if the feedthrough or the base plate cutout is so large that a hand holding a plug can comfortably reach through.
