2 Claims; (01. sin-.103.

The present invention relates to an improved curtain supporting device.

The main object of the'invention is to provide means for lowering and raising the curtain carrying rail to allow an easy changing of the curtains when required.

A further object of the invention is to provide means by which the rail, to which the curtains are detachably attached, when raised to its highest position is hidden from sight.

A still further object of the invention is to provide a simple and relatively cheap curtain supporting device that is easy to operate, and which has an attractive appearance while in use.

These and other objects of the invention will be apparent from the following description taken in conjunction with the accompanying drawing, in which Fig. 1 is a front elevation of a curtain supporting device according to the invention,

Fig. 2 is a horizontal longitudinal cross section through the curtain supporting device shown in 1, and

Fig. 3 shows on a larger scale a transverse section through line III-III in Fig. 2.

The construction shown in Figs. 1, 2 and 3 comprises a bar 2 of substantially L-shaped cross-section with a vertically depending part 2a at the front, and end walls 2b. Suitably arranged lugs l are provided for attachment of the bar in a horizontal position to a vertical surface or wall to form a downwardly opening recess 3 between the wall, the vertical bar part 2a and the end Walls 21).

Inside the horizontal bar part 20 is formed a longitudinal compartment 2| extending substantially throughout the entire length of the bar and having at each end fittings 23 that engage pins 33 attached to each end of a rod 22 having circular cross section, and which otherwise is provided in conventional manner with a self-winding mechanism and pawl means of the type commonly used in roller blinds. On each end of this rod are wound cords l and 8, respectively, and attached thereto, each cord depending through a hole 24 beneath each end of the rod 22, in the lower wall 25 of the compartment 2! and attached to corresponding ends of a rail 4. These holes 24 are preferably oblong to render possible a smooth and unhindered run of the cords in the same direction while being wound on and ofi the rod 22 when this rod is rotated during the raising and lowering of the parallel supporting rail 4 into and out of the recess.

The horizontal rail '4 in the manner of construction illustrated is made of sheet material bent to rectangular cross section, and along its front side has a slot 34 for a number of roller runners 26 eachof which is rotatable on the upper ends of depending arms 28, each of which ends in a clasp 21 serving to support the upper edge of curtains 6. The arms 28 are furthermore attached at intervals to an endless cord, the parts 29 and 30 of which are carried to the interior of the rail 4 through an aperture in the lower side of the rail at one end thereof, and inside the rail are carried over a twingrooved pulley 3|, Fig. 3, and from there over another pulley 32 at the opposite end of the rail.

When the curtains 6 are to be attached to or detached from the rail 4, the depending ends of the cord parts 29 and 30 are held one in each hand, and the rail 4 is pulled down to a suitable height during which movement the cords I and 8 are unwound from the rod 22, while at the same time the self-winding mechanism is tightened. Upon releasing the grip on the cords 29 and 30 the pawl device in the rod '22 will lock the rod and thus retain the rail in its lowered position. The curtain is detached from the clamping means having clasps 21, and new curtains attached, and by pulling slightly at the cord parts 29 and 30 the pawl mechanism is released, and the rail with curtains attached thereto is drawn upwards by means of the self-winding mechanism, until the rail is returned'to the recess 3 behind the depending bar part 2a. The curtains may thereupon be drawn more or less together by means of the endless cord 29, 30, moving the runners 25 along the rail.

To facilitate insertion of the rail 4 into the recess 3 it is advisable to round off the lower inside edges 2d of the vertical bar part 2a and end walls 212.

I claim:

1. In a curtain supporting device the combination of a bar having a longitudinal compartment therein, means for attaching said bar to a vertical surface in horizontal position, a rod rotatably mounted in said compartment, a self-winding mechanism and pawl means coupled to said rod and bar, cord means wound upon each end of said rod and depending therefrom, a curtain rail secured to said cord means below the bar and parallel thereto, a plurality of roller runners carried on said rail and serving for attachment of a pair of curtains, pulley means at each end of the rail, and an endless cord carried on said pulleys and connected at intervals to the roller 3 runners for movement of said runners along the rail to close and open the curtains.

2. In a curtain supporting device the combination of a bar of substantially inverted L-shaped cross-section having a vertical part and a horizontal part and a longitudinal compartment in said horizontal part, means for attaching the bar to a vertical surface with the vertical part of the bar depending and spaced from the surface to define a downwardly opening recess, a rod rotatably mounted in the compartment, a selfwinding mechanism and pawl means coupled to said rod and bar, cord means wound upon each end of said rod and depending therefrom, a curtain rail secured to the cord means below the rod and parallel thereto, rotation of the rod causing the rail to be lowered and raised respectively out of and into the recess, a plurality of roller runners carried on the rail and serving T for attachment of a pair of curtains, pulley 20 4 means at each end of the rail, and an endless cord carried on said pulleys and connected at intervals to the roller runners for movement of said runners along the rail to close and open the curtains.
