DESCRIPTION OF THE PREFERRED EMBODIMENT Refering now in more detail to the drawings wherein like parts are indicated by like reference numerals and initially to FIG. 1, there is illustrated therein a blind which comprises a rotary hollow tube 10 for suspending and winding a curtain 12 therearound. The tube 10 along its longitudinal extention is provided with a slit 14 through which an upper end 16 of the curtain 12 is guided from an open end of the tube 10 for engagement therewith. The tube 10 is also provided at its inner circumferential wall with two or more axially extending ridges 15 for engagement with the channels provided on the periphery of the tube of the coupling means as hereinafter fully described. Opposite ends of the rotary tube 10 is rotatably supported by a fixing means 18 through a coupling means 20.

As best shown in FIG. 1, the fixing means 18 includes a disc 22 having an inwardly projecting square rim 24 which extends over substantially a half of the peripheral edge of the disc 22 across a corner portion 26 and thus it will be appreciated that the square rim 24 includes two straight portions 28, 30 having two recesses 31 respectively through which fitting screws are threaded into the base plate for securing purpose. The

disc 22 is further provided with an inwardly projecting curved rim 32 which extends over the remaining half of the peripheral edge of the disc 22 and opposite ends of the curved rim 32 are abutted to the opposite ends of the square rim 24. In the curved rim two openings 34, 36 are provided in symmetrical relation with the straight portions 28, 30 of the square rim 24. As hereinbefore described the fixing means in accordance with the present invention may be secured to the wall or the ceiling selectively as desired, thus the straight portions 28, 30 may be used selectively for the purpose. For example, when the straight portion 30 is attached to the wall, the opening 36 is used for leading the rope or string. On the other hand, in case the straight portion 28 is attached to the ceiling, the opening 34 is serviceable for the same purpose as shown in FIGS. 3 and 4.

Now back to FIG. 1, the disc 22 at its center is provided with a bearing 38 of substantially horseshoe form with a port 39 somewhat wider than the diameter of the shaft of the coupling means hereinafter described and directed to the corner portion 26 between the straight portions 28 and 30 of the rim 24.

Between the openings 34 and 36 of the curved rim 32 is recessed to form an inlet 40 for the shaft of the coupling means hereinafter described.

The coupling means 20 includes a hollow shaft 42 having at its periphery several axially extending channels 44 adapted to be fitted with the ridges of the hollow tube 10, a flange protion 46 and an outwardly projecting shaft 48 of a smaller diameter than the inner diameter of the bearing 38 and adapted to be rotatably supported by the bearing 36 of the fixing means 18, the parts of the coupling means being integrally formed.

As shown in FIGS. 1 to 3, the pulley means 49 has substantially the same structure as that of the coupling means but the flange 50 is provided at its periphery with a circular groove 52 encompassing the flange 50 around which an endless rope 54 is mounted with a ring spring 56 for depressing the rope 56 to the bottom of the circular groove 52 so that the pulley means 49 when the endless 54 is drawn rotates positively without causing any slipping or idling of the endless rope around the pulley. An outer face of the flange 50 is formed with a circular cavity 58 and a shaft 60 extended therefrom with such a length that the end of the shaft 60 terminates substantially in the plane of the outer face of the flange 50 as will be seen from FIG. 2.

In FIGS. 1 and 5 the curtain 12 at its bottom end is turned up with an expanded end 62 which contains fibrous material therein and is extended over the whole width of the curtain. To the expanded end 62 is attached a weight 64 extending over the complete length thereof. The weight'64 along its whole axial length is providedwith a slot 66 for accomodating the curtain cloth and an expanded groove 68 for receiving the expanded end 62 as shown in FIG. 6.

The end of the curtain is inserted into the weight 64 through either end of the weight and after the complete attachment of the weight 64, a pin 70 having a cap 72 is inserted into the expanded end 62 of the curtain as shown in FIG. 7 so that the expanded end 62 is further expanded to tighten the connection between the expanded end 62 of the curtain and the expanded groove 68 of the weight.

All parts and components of the blind except the curtain and the endless rope are preferably made of synthetic resin.

On installation of the blind according to the invention, the fixing means l8, 18 are secured through their respective square rims 24, 24 to the frame 74 as shown in FIG. 8 and then the coupling 20 is connected to hollow tube 10 with shaft 48 projecting from one end of the hollow tube 10 and the pulley 49 is connected to the opposite end of the tube I0 with shaft facing outwardly. Shafts 48 and 60 after being passed through inlet 40 and port 39 are received in bearings 38, 38.

While, certain embodiments of the invention have been illustrated by way of example in the drawings and particularly described, it will be understood that various modifications may be made in constructions and that the invention is no way limited to the embodiments shown.
