The receiving bore and the at least one bearing space are adapted to accommodate similar elements, which may be in the form of guide pins or pulley shafts, as required. The same idea of a generally simpler type cylindrical type pin as a guide pin or pulley shaft which reduces the number of parts that need to be present initially? Available.

A second aspect of the invention provides a vertical blind headrail assembly comprising a channel-shaped cross-section handrail and at least one end portion attached to one end of the headrail. a cap, a main body portion into which the end cap is inserted into the one end of the head rail; and one main body portion? How much can be inserted into the headrail? A means for deciding, a through hole formed in the main body part for the operation shaft to pass through, a recess formed in the main body part, and the shaft? A hub that can be rotated and inserted into a recess in the end cap and operatively engaged with the shaft? and a housing 7 operatively associated with the drive means and pressed against the outer surface of the main body portion of the 4S cap.

In such an assembly, the shaft drive means may be in the form of a pulley and the housing may be part of the pulley's circumference? The housing is closely wound, and the housing is provided with several cavities or protrusions that are positioned on the body of the cap. The housing can be selectively positioned relative to the housing. With such construction, the protrusion can be attached to the end of the flange of the body portion to allow the protrusion to spring back and allow the cover to be returned to its original position during or after installation of the assembly.

In an alternative construction, the operating shaft drive means may be in the form of a first gear and the housing accommodates a second gear in driving engagement with the first gear, the second gear being operable from the outside.

In this variant construction, the housing can be provided with a bearing 2 for the end of the operating shaft and the second gear can form part of the rod operating structure. Advantageously, the housing is screwed onto the end cap, and the positioning means provided in the body part of the end cap are screw holes.

f) at least one receiving space and a bearing space provided in the body part; g) at least one lace guiding pulley mounted in the receiving space and a bearing for the guiding pulley in the bearing space; h) an end cap. At least two lace guide pins that can be fitted into the receiving holes in the main body of the machine.

With such a structure forming essentially a set of parts, the user can choose several different arrangements to suit the particular nature of the window covered by the vertical blind itself. can have

In order to facilitate understanding of the invention, the following description will be made, by way of example only, with reference to the accompanying drawings, in which: FIG.

Example Referring to the structure shown in FIGS. 1 and 2.

A headrail 10 is shown with a conventional internal longitudinal rib 12. The headrail includes an end cap 14 (FIG. 1) at one end and an end cap 15 (FIG. 1) at the other end.
(Fig. 2) is inserted.

The end caps are nearly identical but mirror each other.

Each end cap has a longitudinal aperture 16 opening into a recess 18 in the body portion 20 . The outer end of each end cap is provided with a four-part flange 22 having a generally planar outer surface 2 for abutting the end s of the headrail 10 and extending the end cap into the end of the headrail. Exercise is restricted to 7.

The outer surface of the end cap is provided with receiving spaces 24, which are separated from each other by partitions 26.

An upper bulge 28 and a lower bulge 30 are formed on the outer surface of one side of the main body portion 20 .

The upper bulge 28 is closed at an end 32.

One or two pulleys 64 are inserted into the receiving space 24 so that the bearing shaft 66 can pass through the pulleys 64 and also through the gap 68 provided in the partition 26.

Both ends of this shaft are accommodated in the upper bulge 62 and groove 66.

Six guide pins 40 of the same structure as the bearing shaft 36 are inserted into the receiving holes 42, so that the traveler string of the vertical ventilation blind is inserted between the pins 40? The pulleys 64 are separated from each other before passing.

The end cap also has screw holes 44 and 46,
The screw hole 46 extends into the lower bulge 60 .

The outer surface of the end cap also includes a resilient tongue 48 having an outwardly extending projection 50 whose distal end is flush with the outer surface of the flange. The pan assembly, which can be folded inwardly into a position, is provided with a conventional operating drive shaft 52, which may be a longitudinally grooved shaft as shown or a traveler shaft. - A shaft may be provided with a spiral groove used for movement and operation. The drive shaft 52 has a longitudinal hole 1 concentric with the recess 18.
It has passed 6.

FIG. 1 shows a drive pulley 54 provided with conventional means for engaging a pole chain and having a hub 56 which has a central opening in the cover generally designated 60. and is accommodated in the recess 1B. Is there a bead chain supported by the pulley 54 on the cover 60? A covering arcuate cover portion 62 is provided. pulley 54
is fixedly held on the operating shaft 52 by a cover 60, a helical helical nut 64, and a spring 66, and therefore,
cover? It is brought into pressure contact with the outer surface of the flan') 22. Is that what Cover 60 has? Circumferential spacing shown in the form of holes extending through the hole? It will be appreciated that the plurality of open spaces 68 are provided. These cavities are positioned to selectively engage projections 50 to position cover portion 62%' in one of several rotational positions.

Figure 2? It will be seen that a similar sliding nut 65 is attached to the outer end of the operating shaft 52 and holds the entire assembly intact.

FIG. 6 shows another type of drive mechanism for the operating shaft. Headrail and 41! Since the s cap is the same as that of the above-mentioned specific example, the same reference numerals as the above-mentioned parts are given. Instead of the drive pulley 54, a! is integrally designated 70! An operating gear box is provided. The gear box 70 includes a housing 72 having a counterbore 74 which accommodates a screw 76 that can be screwed into the screw hole 44, 46 of the housing. Fix it.

A longitudinally extending bearing sleeve 78 is inherently formed within the housing, which sleeve has a through hole 80 that acts as a bearing. have. Shaft 52 in hole 80? Sliding nut 64 to hold? A counterbore hole 82 is provided for housing.

The gear box includes a first bevel gear 84 having a hub 86Y formed with a spline 88 that engages a groove provided in the drive shaft 52.
Contains Kaoru.

The first bevel gear is a hub 88 that is rotatably mounted within a bearing portion 90 formed in the housing. a second bevel gear 8 having
7, the hub has a ball-shaped connection 92χ adapted to connect to the rod-shaped operating member. When the rod-shaped operating member is twisted twice, the two bevel gears, and therefore the operating drive shaft 52, are rotated.

This embodiment also includes a flat nut 65 that presses against washer 94 and a spring 96 that holds drive shaft 52.

Effects of the Invention Accordingly, one can change the pulley drive device shown in FIGS. 1 and 2 to the rod-operated gear device shown in FIGS. 6 and 4 due to the structure of the end cap of the present invention. Make it available for arbitrary use.

Are all these drives completely standard end caps?
It is structured so that it can be used and attached to either of the head rails.

Therefore, there are only 14 parts in the structure of the present invention. Use a right-hand or left-hand control for horizontal or inclined equipment, a dual-purpose chain-type control for right- or left-hand horizontal equipment, or a string and rod for right-hand or left-hand horizontal equipment. It is possible to have a control #J part v. Therefore, does the structure of the present invention have maximum flexibility with a minimum number of parts? I can demonstrate it.
