Cable support to be installed in connection with a ladder. Kabelhällare, som monteras i samband med en trappstege.

The invention relates to a cable support to be installed in connection with a ladder, which consists of an angle-shaped piece of rail, the other end of which can be attached to the ladder.

Ladders with cable supports are used, for example, in connection with radio and other telecommunication masts. Known cable supports are attached to the ladder either by welding or by screw connections. The disadvantage of welding fastening is that the future need for cabling must be known in advance. Attaching the brackets with bolted joints is slow and cumbersome.

The object of the invention is to provide a cable support which can be easily and quickly installed in connection with a ladder according to the current need.

This object is achieved by a cable carrier according to the invention on the basis of the features set out in the appended claims.

In the following, an embodiment of the invention will be illustrated with reference to the accompanying drawings, in which Figure 1 shows the fastening end of a cable carrier according to the invention fitted in connection with a ladder.

Figure 2 shows the fastening end of the cable holder in the applied state, i.e. before it is bent into an angle-shaped rail piece.

Fig. 3 shows a cable holder according to the invention seen from the end of the fastening end, and Fig. 4 shows the fastening end of a cable holder seen from above.

The cable support is made of a flat plate, the fastening end of which is stamped in the shape shown in Fig. 2 before the plate is bent. The length of the bracket can be selected to suit the need. Notches 3 and 8 are stamped on opposite side edges of the plate, the round bottom portions of which are aligned transversely. The side edges of the notches 3 and 8 are made obliquely oriented as shown. An incision 5 is made in the end of the plate, below which a tongue 6 is left. and in the region between the end of the rail piece there is a part 2a bent downwards from the edge of the upper horizontal side 2 so as to form a U-shaped trough 4 dimensioned so that the step or spool 11 of the ladder 10 fits into this trough. As can be seen in Figure 1, the oblique orientation of the side edges of the notches 3 and 8 means that the cable load pivoting the bracket down locks the notches 3 and 8 in the ladder upright 12. If necessary, the fastening

The ladder shown in dotted lines in Figure 1 is of such a design that in the middle there is an actual vertical load-bearing frame, which at the same time forms the running rail of the seat belt carriage. The vertical supports 12 at the edge of the ladder are round in cross section and relatively small in diameter.
