Device for pulling cables into cable trays.

The present innovation relates to a device for pulling cables of any type on so-called cable trays, cable shelves, or cable bridges like that. Cable racks are often in buildings,

preferably in the basement, but also in workshops and the like Commercial premises are provided. They are used for mounting and laying without clamps of cables and wires of all kinds, but preferably for energy cables. Also in buildings For sporting events, shafts in mines, even in larger ships, cables are attached to them Platforms or shelves relocated.

The peculiarity of such cable racks is that they are generally for reasons of space but also for reasons of asthetics are installed relatively close under the ceiling, which makes laying the cables extremely difficult, not in the end, because in many cases the distance between the bed and the floor on which the cable is initially laid is not is always constant.

It is known and practiced when pulling cables single S-shaped iron hooks (meat hooks) on beds at a certain distance with one bend on the edge of the bed hang in and the cable to be laid only to lead over the other curvature of these hooks and from to lay there on the bunk. However, the cable cannot be pulled properly over such makeshift hooks, as the Cable does not slip into the hook. Guiding around corners etc. is also not possible with such a provisional solution. Beyond that there is a risk of injury.

The device according to the invention avoids all these disadvantages and enables a simple and safe installation

supply of cables on trays, shelves, etc., even if these are arranged close to the ceiling or at an angle are led. The device according to the invention is only used temporarily as an auxiliary device on the cable carrier attached, namely hooked. In contrast to other such auxiliary devices, the device exists according to the invention in that it is a U-shaped which can be moved up and down on a hanging rod Guide part is formed, which carries a horizontally arranged, freely rotatable roller in the lower area.

In order to ensure that the cable is routed as smoothly as possible, even around corners, according to a further development proposed the idea of the invention in the U-shaped guide part laterally in the immediate vicinity of the legs to attach two vertically arranged, also freely rotatable rollers.

The use of the device according to the invention takes place in such a way that it laterally over the entire length of a cable tray distributed to be attached to this. After that, the cable is on these devices to the end for example pulled along with the help of a winch and then placed in the bed by hand.

A major advantage of the device according to the invention over conventional roller guides is the vertical, continuous adjustability of the guide part. This means that height differences in the course of the cable racks can be easily compensated for. The adjustment

len is done simply by using a clamping screw, preferably in the form of a wing screw, loosens the guide piece, adjusts it to the desired height and the Tighten the clamping screw again.

Details of the device according to the invention are based on the drawing, which shows two embodiments, explained.

Here shows

Figure 1 shows the configuration of the device for use in multi-storey Zabelabitschen or cable shelves, while

Figure 2 shows the configuration for use on single-story cable trays.

In both figures, 1 denotes a cable tray, which is attached to the support wall via the stiffening ribs 2.

In the embodiment according to Figure 1 is below the cable tray 1 another cable tray 3 is provided. Accordingly, it preferably has a rectangular shape Cross-section having suspension rod 5 of the device According to the invention, an upper and a lower fastening claw 10 and 11, respectively, over which the entire device pendulum-free can be hung on the edges of the two cable racks.

To accommodate the cable in the case of assembly, the U-shaped guide rope 6 is provided, which in the lower Bereioh with a

horizontally, arranged, freely rotatable roller 7 and the ielt-high rollers 8 equipped 1st. This entire unit let at the Guide sleeve 9 attached, which on the suspension rod § naoh above and below vereohoben and duroh in every position Tlügeleohraube 19 can be locked.

The device complies with all structural conditions To be able to adapt is also the lower fastening claw 11 on a sleeve 12 that is displaceable on the suspension rod 5 attached, which in turn can be clamped old the wing earring 13.

In the case of the exemplary embodiment according to FIG. 2, a support part 14 is provided which consists of a rod 15 which is attached to an adjustable sleeve 12 'and which is telescopically inserted into a tube engages, which has a support foot 17. This also means that the single-story cable racks can be suspended without swinging The effective length of the support part 14 can be changed with the aid of the clamping wing screw 18 and can be clamped steplessly in any desired length.

The device according to the innovation is not limited to the embodiment described. Rather, under the The following claims, modifications are possible, for example, the upper fastening claw can be arranged in a height-adjustable manner in order to allow the guide part together with the guide rod, which can also be a pipe, to be made variable in height. Also polygonal cross-sections of the suspension rod or tube and accordingly also for the guide sleeves are conceivable

although a circular crosswise clearance of these parts is possible because of the risk of twisting the guide part. If the abutment part in the embodiment according to FIG. 2 is also articulated to the suspension rod 5 , ie can be connected to it via a hinge in order to facilitate storage in the event of emergency use, this is only mentioned for the sake of convenience.
