Abstract

The mating rods (11, 12, 13) of a telescopic curtain rod have a C-profile with inwardly bent edges (14, 15) which make the rods stiff and provides an arched surface on which curtain supports (20) can slide. Some of the rods have a portion with parallel slots (30) in their back, which permits the rod to be bent towards its back (16). Only a few elements will provide for a great versatility in curtain rod arrangements.

Description

A curtain rod

Technical field

This invention relates to a curtain rod made up of two or more telescoping C-profile rods.

Background of the invention and brief description of prior art

Since long, telescopic C-shaped curtain rods have been common on the market. They are sold as straight rods and as rods with pre-bent bends. They cannot be bent without a fixture.

A stiffer C-shaped profile with inwardly bent edges is known from US-A-1 ,914,132. It is an advantage that curtain supports can be used which slide on the arches that are formed.

A curtain rod which can be bent manually on site is known from US-A-2,890,799. It comprises two C-formed rods with sharp corners, one in the other as if they were telescopic. The compound rod cannot, however, be adjusted in length.

Object of invention and brief description of the invention

It is an object of the invention to provide a telescopic curtain rod, which is straight and stiff and still can be bent manually. To this end, a curtain rod is provided in which the C-profile has inwardly bent edges that form arches on which curtain supports can be placed to be slidable thereon, and at least one of the telescoping rods has a portion, limited in length, that has a plurality of parallel transverse slots in the back of the C-profile so that the profile can be bent towards its bac but still permit the curtain supports to be moved on the arches through the bend.

Description of the preferred embodiment that is shown on the figures. Figures 1 and 2 show a curtain rod that is made up of two C-shaped rods 11 ,12 that are telescopically inserted in both ends of a rod 13 of the same shape. The rods have their two edges 14,15 inwardly bent so that the total bend from the back 16 of a rod is about 360 degrees or more, and the inwardly bent edges form stiffeners. A curtain support 20 is shown which has a front plate 21 , a horizontal cylindrical part 22 that slides on the arches 19 of the rods, and a back plate 23 that is supported between the arches and the back of the respective rod. The outer one of the telescopic rods, the rod 13, was made from a steel strip that had its ends tapered so that the rod now has helical ends 24,25 and 26,27 climbing gradually up onto the inner rods 11 ,12 so that the support 14 will gradually climb up onto the outer rod when moved from an inner rod to the outer rod 13.

Figure 3 shows a flat sheet steel strip from which the inner rods 11 , 12 are made by roll-forming. The strip has portions with a plurality of slots 30 and one such portion is shown. Figure 4 shows the rod with the slots 30 that reach from the back of the rod halfway or a little more through the thickness of the rod. Figure 5 shows the same rod bent in the portion having the slots 30. As shown in figure 3, each slot has a portion with parallel walls and this portion extends over the flat part of the back of the finished rod profile. The ends of the slots are tapered and they extend into the bends of the rod profile. Figure 6 shows schematically a curtain rod of the kind shown in figure 5 with a central "outer" rod 13 and two " inner" rods 11 ,12. The rods 11 ,12 have portions 31 ,32 of slots as described with reference to figure 3 in which they have been bent and they are also telescopically inserted into pre-bent end rods 41 ,42, the ends of which are fixed to supports on the wall in a conventional manner. The two end rods 41 ,42 are of the same " outer" type as the rod 13. Since the two rods 11 ,12 are telescopically arranged in both their ends, the arrangement can be adjusted for example to bay windows of various sizes and forms. The rods are stiff because of their inwardly bent edges and the limited lengths of the slotted portions will not reduce the stiffness much since the rods are normally bent to curves in these slotted portions.

Figure 7 shows a curtain rod arrangement in which there is no central rod as in figure 6. Instead, the two rods 11 ,12 are of different kind so that one fits in the other. The two end rods 41 ,42 are also of different kind.

Curtain rods of almost any size and form can be made up with the few elements shown in figures 6 and 7.

Claims

1. A curtain rod made up of two or more telescoping C-profile rods (11 ,12,13,41 ,42), characterised in that the C-profile has inwardly bent edges 14,15 that form arches (19) on which curtain supports (20) can be placed to be slidable thereon, and at least one of the telescoping rods (11 ,12,13) has a portion, limited in length, that has a plurality of parallel transverse slots (30) in the back (16) of the C- profile so that the profile can be bent towards its back but still permit the curtain supports to be moved on the arches through the bend.

2. A curtain rod according to claim 1.characterised in that the ends of the arches (19) of the outer one (13) of two mating rods have helical form.
