CURTAIN RAIL Filed Oct. 4, 1955 INVEHTOR ATTORNEYS.

Patented Sept. 21, 1937 UNITED STATE awaits PATENT @FHQE Application October 4, 1935, Serial No. 43,492 In Germany October 6, 1934 15 Claims.

This invention relates to curtain rails of the kind comprising a slotted tube in which is disposed one or more carrier rails for the runners to which the curtain rail is to be attached, (hereinafter referred to as of the kind described).

In a known construction of the kind described the carrier rail and tube are made in separate parts, but the carrier rail is fixedly arranged in the tube. Bending of such a tube is practically impossible without incorrectly shaping the carrier rail. Further, in another known construction in which the carrier rail has to be inserted from one end into the tube, bending is very difficult because the insertion of the carrier rail after separate bending is not practicable. Moreover, the carrier rail is secured by lips pressed in the tube, or by special brackets engaging from outside in the tube, so that the outer surface of the tube is unpleasantly interrupted by the heads of nails, or screws, or incisions or brackets.

One object of the present invention is to provide a curtain rail of the kind described in which the rail and tube may be bent separately and subsequently easily assembled.

Another object of the present invention is to provide a curtain rail of the kind described in which the outer tube presents a smooth uninterrupted surface.

Another object of the present invention is to provide a curtain rail of the kind described in which the carrier rail or rails may be readily disconnected from and connected to the slotted tube.

According to the present invention means are provided for supporting the carrier rail in the slotted tube which permit the rail to be inserted into and withdrawn from the slotted tube through the slot therein.

The carrier rail may be supported in the slotted tube by a number of supports, the arrangement being such that the rail and the said supports can be simultaneously inserted into or withdrawn from the slotted tube.

The supports may be in the form of brackets which can be collapsed to pass them into the slotted tube and subsequently opened out when in the tube, the said brackets being supported in the tube.

In carrying out the invention the carrier rail for the runners may be supported on spring brackets or like members which can be sprung into the tube and supported therein.

The spring brackets or like members may suitably be supported along the inner edges of the slot in the tube, the said edges being preferably curled over to form horizontal supporting surfaces. The carrier rail and tube can, therefore, easily be again separated at any time without undoing screws, rivets, or the like. Moreover, the slotted tube can be separately bent and/or formed into an angle, and, subsequently the carrier rail,

ners 4 (Fig. 5) can roll. 3 indicates the means employed in each case for supporting the carrier rail in the tubular casing l.

The tube l is made of iron having a brass coating, and the open edges are curled over as at 8 to form substantially horizontal bearing surfaces for the lower ends of the brackets 3, which are also preferably curled over as at 9.

Referring more particularly to Figs. 1, 3, 4 and 5, the tube i is in each case of circular crosssection.

In Fig. 1 the bracket 3 is pressed inwards at it to form a neck, so that the bracket can be slidden over the upper flange of the I-section. carrier rail 2, the neck H1 forming thus a supporting surface for the rail 2. In Figs. 3 and 3 a tongue H is stamped out of the bracket 3 and turned downwards. The tongue II is provided with an aperture i2 by means of which it can be secured to the end of the web of the inverted T-section rail 2 by a screw, the web of the section 2 being provided with a corresponding screw aperture. In Fig. 4 the walls of the bracket 3 are pressed together at the apex as indicated at M and the inverted T-rail 2 is connected to the bracket 3 by a screw bolt l5 passing through apertures in the walls M and in the web of the rail 2. In this figure the lower ends of the bracket 3 are curved to embrace the edges 8 of the tube I and the curved ends project somewhat below the edges 8, thus forming a convenient means for inserting and removing the bracket. In Fig. 5 the upper flange of the I-rails 2 is engaged by tongues I6 stamped out of the material of the brackets. This figure also shows the runners 4 in position on the lower flange of the I-rall.

In the form shown in Fig. 2 the tube I is a trough section open at the bottom. In this figure two- I-rails 2 are carried in two pairs of tongues it stamped out of the material of the brackets 3. In this figure also one side of the bracket 3 is hingeably connected at 263 to the body of the bracket. In this form the bracket 3 may be made of springy material or otherwise. If it is not made of springy material the bracket can be passed through the slot in the tube I by moving the side hinged at 20 around the hinge, thereby reducing the width of the bracket during its passage through the slot.

It will be understood that the invention is in no way limited to the particular shape of the tubes I and bracketsS shown, nor to the sections of carrier rails shown.

In order to mount the rail 2 in the tube I, the rail 2 is first connected to the brackets 3 and the assembly can then be passed into the tube 1 through the slot therein, the brackets 3 thereupon opening out in order to be supported on the edges 8 adjacent the slot. As previously mentioned the rail can subsequently be readily removed from the 5 tube by pressing the walls of the bracket 3 together and drawing out from the tube. Thus the parts can readily be assembled or separated after they have been individually bent, or curved.

It is to be understood that the tube I may be made of any other suitable metal or material; further, the brackets 3 and section 2 can be made of any suitable material.

It is to be understood that all the supports or brackets 3 shown in Figs. 1 and 3-5 may be arranged to suspend more than one rail 2 in the tube I, the brackets being suitably shaped and provided with means for engaging the rails.

What I claim and desire to secure by Letters Patent is:
