Description

This invention refers to a guide for sliding curtains and similar, of the type known in practice to the prior art comprising a support rail, with straight and/or curved sections, provided as required with slotted holes for direct attachment to the ceiling, with its side arms bent inwards at the ends. The multiple hangers, from which the curtain or similar is suspended, and reversible devices for crossing over and/or overlapping the outside edges of the curtains slide along the inside of the rail. The guide also comprises curtain cord guide and/or return terminal pieces at its ends, other intermediate angle connectors between adjacent rail sections, support fixtures for fastening the guide to the wall or ceiling, and stretchers for the afore-mentioned curtain cord.
There are many curtain guides known nowadays, but in all of them, when the curtains has to follow the recesses and protrusions of the walls in a room, the guide installer is compelled to use an adequate tool to bend the guide on site, adapting it to each variation of shape of the wall (columns, window spaces, blind cases, etc.)
Moreover, if the guide shows several bends or non-aligned sections, it is necessary to install independent guides in order to ease the motion of the curtain, either if this motion is carried out manually or by a cord. This causes the inconvenience of the curtains remaining separate, losing unavoidably their decorative unity.
By means of the guide subject of the present invention, all these inconveniences are completely avoided, since with it the installer will assemble the guide very comfortably and in accordance with his needs, using the appropriate guide elements which, all together, constitute the subject of the present invention.
The guide in question is characterised by the fact that the above-mentioned rail is fitted with inner lips designed for contacting at the bottom with the top of corresponding inside shoulders provided on the above-mentioned terminal pieces. The rail is also fitted with longitudinal recesses designed to receive their respective close-fitting connectors, consisting of rods provided with a centre slot.
According to a preferred feature of the invention, each terminal piece consists of a framework which comprises a main body with two side skirts linked by three bridge portions These have four inner side slots cut in them, facing each other in pairs. Curtain cord guide and/or return pulley spindles can engage in these, with a choice of two positions each. Each of these spindles is firmly engaged at the bottom of a corresponding pair of slots by the tight fit of its outside edges against the bottom. Each spindle end is prevented from coming out of its portion of slot since this narrows near the bottom. The main body is provided in one end bridge portion with a self-tapping screw to be applied against the inside face of the top centre arm of the rail. Each terminal piece may be fitted with an end cover piece or an intermediate cover piece, for coupling to the respective terminal and for housing at least one curtain hanger.
Other features and advantages of this curtain guide in question will be drawn from the description set out below with reference to the drawings attached, which illustrate, solely by way of example, one way in which it may be produced.

In these figures we may see that the guide in question, represented diagrammatically in Figs. 1 and 2 in just one of the ways in which it may be produced, comprises a support rail 1 with either straight sections (Figs. 4 and 6) or curved sections (Figs. 8, 9, 19 and 11), provided as required with slotted holes, with its side sections 3 bent inwards at the ends 4. Multiple hangers 5, from which the curtain or similar, not shown, is suspended, and reversible devices 6 for crossing over and/or overlapping the end edges of the curtains slide along the inside of the rail 1.
The guide 1 also comprises guide and/or return terminals 7 for the curtain cord 11, other intermediate angle connections 27 between adjacent sections of rail 1, support fixtures 9 for attaching the guide to the wall or ceiling, and stretches 10 for the curtain cord 11.
The rail 1 is equipped with inner lips 12 designed for contacting at the bottom with the top of corresponding inner shoulders 13 provided on the respective terminals 7.
The rail 1 is also provided with longitudinal recesses 14 designed to receive respective close-fitting couplings 15, consisting of cylindrical rods provided with three incisions 16 with centre slots.
Each terminal 7 is made up of a framework which consists of a main body with two side skirts 17 linked by three bridge portions 18, 19 and 20. Cut in each of these are four inner side slots 22, opposite each other in pairs, in which the respective spindles of the curtain cord guide and/ or return pulleys can engage, with a choice of two positions each. Each of these spindles is engaged firmly at the bottom of a corresponding pair of slots through the tight fit of its edges against the bottom. Each spindle end is prevented from coming out of its portion of slot through a constriction 24 in it near the bottom.
In the end bridge portion 18 the main body is provided with a self-tapping screw 25 for tightening against the inside face of the top middle arm of the rail 1.
Each terminal 7 may be fitted with an end cover piece (Figs. 16, 17 and 18) or an intermediate cover piece 27 (Figs. 20 and 21) for coupling to the respective terminal 7 and for housing at least one curtain hanger 5.
Either of these cover pieces 26 and 27 comprises a first hollow outer portion 28 designed for its attachment 5 to the wall or to the ceiling by means of the holes 29 and 30 drilled in it. Each cover piece 26 or 27 comprises a second middle portion 31 with inner shoulder 32 designed for resting against the inner flanges of the rail 1 and with a bottom recess 33 for housing the head of a curtain hanger 5. It also has a third inner portion 34 consisting of a block designed so that a vertical screw 25 may be threaded in for tightening against the inside face of the top arm of rail 1 for attachment purposes.
The guide comprises at least one stop and hanger piece 35 (Figs. 26, 27 and 28), consisting of a lower portion with a hanger ring 36 and an upper portion which is made up of a vertical stem 37 and a rectangular-shaped plate 38 perpendicular to the stem 37. This plate is slightly domed underneath and it has a width somewhat less than that of the bottom longitudinal opening 40 in the rail and a length somewhat less than that of the inside width of the rail 1.
If the vertical stem 37 of the piece 35 is inserted vertically inside the rail 1 so that the plate 38 perpendicular to the stem 37 is situated lengthwise to the opening 40 and this stop and hanger piece 35 is then turned 90°, it becomes firmly engaged in the rail 1 with the stem 37 resting against the inside of the top horizontal arm of the rail 1 and with the plate 38 perpendicular to the stem 37 resting against the in-bent ends 4 of the side arms 3 (Fig. 26).
The guide also comprises at least one locking piece 39 for the opening 40 in the rail 1, which has a basically flattened rectangular configuration with an inverted U cross section. The side arms 42 of the piece 39 have lengthwise grooves 43 designed to receive the respective free edges of the arms 3 of the rail 1.
This locking piece 39 is composed of a resilient flexible material which allows it to be pressed up into the opening 40 in the rail 1 through elastic deformation of the piece. It is also removed through elastic deformation by pressing the side arms 42 of this piece 39 towards each other until the ends 4 of the side arms 3 of the rail 1 are freed from the side grooves 43 in the piece 39.
The crossover and overlap device 6 comprises one or two supplementary curtain support slides 44. Each of these has a pair of slip elements 45 located on top of the ends of the slide 44 and provided with a flat, smooth, horizontal top surface 46 designed to support the curtain cords 11.
Each of these slip elements 45 has a transverse rear sharp edge 48 designed to help guide the cords 11 on their way down to the body of the slide 44.
This body consists of a horizontal U-section plate placed vertically and provided with a centre hole 50, two notches 51 in the bottom edge and a lower transverse flange 52 with an inverted T cross section. All this is to allow the cord 11 to be wound through the hole 50 and the notches 51 so that the slide 44 is attached firmly to the cord 11.
The body of each slide 44 has a hole 47 below each slip element 45 either to receive a hanger of the moving end or ends of the curtain or suitable fastenings for a reversible crossover or overlap plate 53. This also has holes 54 for receiving curtain hangers 5 or else an operating rod 55 (Fig. 2).
The stretchers 10 comprises at least one gravity tensioning device for cords 11 which consists of (Figs. 35 and 36) a centre weight body 56 with heads 57 firmly attached at either end that also hang from the cord loop 11.
Each head 57 comprises a hollow outer cap 58 with an inlet 59 in its end base for the cord 11 in approximately semicircumferential arc. It also has an L-section inner middle portion 60 with a half-doughnut-shaped notch 61 where cord 11 slides and an inward-facing lip 62 designed to prevent fortuitous movement of the cord 11. Inside each cap 58 there are reinforcement ribs 63 which also act as buffers for the centre load body 56.
Each fixture 9 for supporting or attaching the guide to the wall or ceiling comprises a lockplate 64 for fastening to the horizontal arm of an angle bracket (Figs. 37 and 38) or directly to the ceiling (Fig. 39). The lockplate 64 is fitted with a swivel plate 65 with bottom fins 66 for fitting into side grooves 14 (Fig. 3) of a lengthwise inverted T-section channel in the rail 1. This swivel plate 65 has a curved operating rod 67.
In Fig. 19 we may a shim 41 designed to be applied over piece 26 or piece 27 (Figs. 16 and 20) in order to compensate for the difference in height of the rail 1, in the event of it not being attached directly to the ceiling.
Two ways of producing a hanger 5 are illustrated in Figs. 22 to 25. In both cases they comprise a bottom part with a hole 68 and, in the case of Figs. 22 and 23, rolling members 69, whilst in the case of Figs. 24 and 25 they include sliding members 70 and a flange 71 to stop them getting inside the rail 1.
