Definitions
- This invention relates to a cable duct transition piece which, in use, forms a transition from a first cable duct located in a first plane to a second cable duct located in a second plane, the first and second plane having a line of intersection adjacent to which the cable duct transition piece is located.
- Such a cable duct transition piece is known per se in the form of a tubular bend of, for instance, 90° .
- This tubular bend is mostly constructed from metal.
- a disadvantage of the known cable duct transition piece is that it is only applicable at a predetermined angle included by the first and second plane. In the example mentioned, this angle is 90°, but there are also transitions known where the angle is equal to 45°.
- the cable duct transition piece according to the invention meets the disadvantages outlined and accordingly is characterized in that the cable duct transition piece comprises a first bottom part, a second bottom part remote from the first bottom part, and opposed upright sidewalls extending in a feed-through direction for a cable, which extend along the first and second bottom part and which connect the first and second bottom part with each other, the upright sidewalls being manufactured, at least for a part, from a flexible material, so that the angle included by the two planes can be varied by bending the upright sidewalls.
- a further disadvantage of the known cable duct transition piece is that it is not adapted to be coupled, on one side, with the cable duct known per se, which comprises a bottom having a plurality of mutually spaced grooves extending in the longitudinal direction of the cable duct part, and, on the other, with a tubular cable duct. According to the features mentioned in claims 2 and/or 3, that disadvantage is also resolved.
- the invention also relates to a cable duct system comprising an upright cable duct part, a horizontal cable duct part, and a cable duct transition piece as described hereinabove.
- a cable duct system is characterized in that the first bottom part of the cable duct transition piece is attached to the first cable duct at a free end of the first cable duct, and the second bottom part of the cable duct transition piece is attached to the second cable duct at a free end of the second cable duct.
- Fig. 1 shows in perspective a view of a possible embodiment of a cable duct transition piece according to the invention
- Fig. 2 shows a side elevation of the cable duct transition piece according to Fig. 1 in the direction of the arrow P;
- Fig. 3 shows a top plan view of the cable duct transition piece according to Fig. 1;
- Fig. 4 shows a side elevation of the cable duct transition piece according to Fig. 1 in the direction of the arrow P'; and Fig. 5 is a cable duct system comprising a cable duct transition piece according to the invention.
- reference numeral 1 designates a cable duct transition piece according to the invention.
- the cable duct transition piece forms, in use, a transition from a first cable duct 2 located in a first plane VI (see Fig. 5) to a second cable duct 4 located in a second plane V2.
- the first and second plane have a line of intersection 6 adjacent to which the cable duct transition piece 1 is located.
- the cable duct transition piece 1 is represented in unbent condition. Then the two planes in fact coincide.
- the cable duct transition piece 1 comprises a first bottom part 8, a second bottom part 10 remote from the first bottom part 8, and opposed upright sidewalls 14, 16 extending in a feed-through direction 12 for the cable.
- the upright sidewalls 14, 16 in this example extend along the first and second bottom parts 8, 10. Further, the upright sidewalls 14 and 16 connect the first bottom part 8 and the second bottom part 10 with each other.
- the upright sidewalls 14, 16 are each at least partly manufactured from a flexible material, so that the angle included by the two planes VI and V2 (see Fig. 5) can be varied.
- the upright sidewalls 14, 16 are manufactured in their entirety from a flexible material.
- the first bottom part 8 in this example is provided with a plurality of spaced uprights ridges 18, between which grooves 20 are formed each extending in the above-mentioned feed-through direction 12 .
- cables 22 in use, in the grooves mentioned, cables 22 (see Fig. 5) can be received.
- the upright sidewalls 14, 16 Adjacent the second bottom part 10, the upright sidewalls 14, 16 are bent towards each other at their upper side. The arrangement is such that in fact a tubular lead-through 24 is formed for the cables 22. Further, the upright sidewalls are higher adjacent the second bottom part than adjacent the first bottom part. In this example, further, the first bottom part, viewed in the direction transverse to the feed-through direction 12, is wider than the second bottom part. This appears clearly from Fig. 3, where the first width is indicated with the arrow B, while the second width is indicated with the arrow B'. It holds therefore that B' is smaller than B. As a consequence of all this, the upright sidewalls 14, 16 taper towards each other in the feed-through direction 12.
- the entire cable duct transition piece is manufactured from an elastomeric material.
- a cable duct system can thus be formed which comprises the first cable duct 2, the second cable duct 4 and the cable duct transition piece 1.
- the angle ⁇ will have a value unequal to 180° .
- the second cable duct is of tubular design.
- the first cable duct 2 comprises a bottom 26, with a plurality of mutually spaced grooves 28.
- the grooves 28 extend in the longitudinal direction of the first cable duct 2.
- the design is such that the first bottom part 8 with the above-mentioned grooves 20 has the same shape as the first cable duct 2.
- an end face 30 of the first cable duct abuts against an end face 32 of the cable duct transition piece.
- the first cable duct is then connected with the cable duct transition piece by means of pins 34.
- Each pin 34 extends in an opening 36, which is provided in the end face of the first cable duct 2, and in an opening 38 which is provided in the end face of the first bottom part 8.
- the second bottom part 10 can be slipped into the tubular second cable duct 4.
- An advantage of the construction is that the second bottom part 10 can be slid into the second cable duct over a flexible height H (see Fig. 5). Assembly is thereby facilitated.
- it holds that the first cable duct 2 is horizontally directed, while the second cable duct 4 is vertically oriented.
- the first and second cable duct can also assume other different relative positions. Such variants are understood to fall within the scope of the invention.
