Description
~ 5~7 A RETRACTABLÉ SCREE~
.
BACKGROUND OF T~E INVENTION
The present invention relates to a retractable screen, such as a venetian blind, a folding blind or curtain or a roller blind which can be gathered ~ogether.
One known form of such screen comprises a headrail, 5 lateral profiles extending generally perpendicular from each end of the headrail, a bottom rail having end portions movable in said lateral profiles and d~aw-cords connected to the bottom rail. The draw-cords may be connected to a sli~e which is mounted for movement along the lateral profile so 10 that movement of this slide actuates the bottom rail via the draw-cords. The slide, however, does not permit the bottom rail to move up and down other than by means of the slide, so that, particularly in the event of failure or seizure o~
the slide, the blind cannot be moved up or down.
It is an object of the present invention t~ improve the slide of the type mentioned initially, in such a way that other means may be provided for actuating the retractable screen.
According to the present invention there is provided a retractable screen comprising a head rail, lateral profiles extending generally perpendicular from each end of the headrail, a bottom rail having end portions movable in said lateral profiles, draw-cords connected to said bottom 25 rail, a slide mounted on one of said lateral profiles, passages formed in said slide, said passages opening into the front face of said slide, the draw-cords passing ~hrough said passages, operation of said draw-cords causing raising or lowering of said bottom rail, said draw-cords extending 30 to the front of said slide, so that they may be manually gripped and pulled.
The movement of the bottom rail can be achieved 75~
simply by manually acting on those portions of the draw~cords which extend to the front of the slide, the slide normally then being fixed in position on one of the lateral profiles.
Preferably~ however, provision is provided to clamp ~he draw-cords to the slide, whereby movemlent of the slide longitudinally of said one profile will cause movement of the draw-cords and thus of the bottom rail. With such a construction, however, it is possible preferably to release lO the clamping means and to adjust manually the portion of the draw-cord which is at the front of the slide. This overcomes the problem when one or more of the draw-cords is lying too loosely in the retractable screen and has to be tightened. This retightening can be readily achieved by the 15 release of the clamping means in the slide, pulling on the cords and reclamping. This can be carried out even by an unskilled person.
In a preferred construction, the slide is generally rectangular, having two longer and two shorter sides, and 20 possibly being rounded at the shorter sides With such a construction, it is preferable that the passages on the two shorter sides of the side should each begin in the region of a part of the slide which extends in a longitudinal channel formed in the lateral profile. The passages may include a 25 first arm parallel to the lateral profile and a second arm essentially perpendicular thereto.
The clamping means, where provided, may comprise a screw having a portion engageable with the cord passing through the pa~sage. This portion may be the head of the 30 screw and the screw shank can be arranged to extend parallel to the second arm of the passage.
Simple and easy locking of the slide may be achieved if a locking member is movable in the slide substantially perpendicular to the lateral profile, and has a head part 35 engaging in the profile so as to be moved relative to the rest of the slide in order to exert a clamping pressure on ~s~
-3~
the profile. The loaking member can include a thread on the front face of the slide, on which a nut is threadably engaged to exert the clamping force. A nut of this type aan be actuated partiaularly easily by hand, on the front face of the slide, without the use of tools.
In order that the invention may more readily be understood, the following description is given, merely by way of example, refer~nce being made to tho aacompanying drawlngs.
~IEF QESCRIP~ION QE~E DRAWIN~S.
In ths drawing~:
Figure 1 is a half section through one embodiment ox slide shown installed in one form o~ retractable screen according to the invention;
Figure 2 is a front view of the slide housing; and Figure 3 i~ a perspeative view o~ a complete venetian blind constructed aoaording to the inv~ntion, provided with a slide according to Figures 1 and 2.
~E~RI~IQ~ Q~ ~HE_P~E~RED E~ODIMENT
~he retractable screen on which the slide is to be U6 ed may be a venetian blind, a folding blind, a folding curtain or a roller blind. ~he invention is desaribed with refererlae to a venetian blind.
Figure 3 ~hows suah a blind whiah can be fitted to the in~ide of a sloping skylight, particularly of the tiltable type. The blind has a horizontal headrail 1, which i~ U-shaped in aross-section and from wh.tch ladder aords 2 hang down, these ladder cords being indicated in broken lines in Figure 3 and holding the individual s~at~, which are not shown, at the neces~ary distance apart from one another. A longitudinal tilt rod (not shown) is mounted in a conventional manner in the headrail 1 and can be rotated by means o~ a tilt bar 3 in order to turn the slats by mean~ o~ the ladder cords 2.
Pro~ectlons formed on corner part~ 4 are pushed into the end of the headrail 1, these corner parts 4 ~orming ft~, ~5~
the connection between the headrail 1 and lataral profiles 6. The lateral profiles 6 are fixed to the lower part~ o the generally square shaped corner part3 4 and extend downwards on both sides of the winaow~ 80 that in the case of a sloping skylight, the profilss 6 are parallel to the sloping window side pieces.
Two lateral profiles 6 are each formed with a front and a rear channel through whlah the v~netian blind draw-cords can run. These channels are open to the front and rear, respectlvely, over their entire length.
In the front channel of the left profile 6 a handle or manually actable slide 35 can be moved up and down along the profile. ~his slide has a housing 36 which is approximately square as seen in the cross-section in Figure 1, an~ approximately reotangular in end view as seen in the orthogonal vlew of Flgure 2. ~he bottom part 35~ of the slide 35 extends into the channel, engaging inturned side pieces of the channel. When assembled together with a clamping member 47 discussed below, the slide 35 is clamped to the profile 6. Lift cords (I to IV) are arranged in the front channel and are threaded into the slide 35 on both shorter sides of the housing ln the bottom part 35~. For thls purpo~e the slide 35 has apertures 37, 38 on both shorter sldes, which represent the ~tart o~ passages 39,40 in tha housing 36. trhese passages 39,40 are curved, beginning in portions extending parallel to the pro11e 6 and ending in the apertures 37,38 and end in portions extending perpendicular to the profile 6, which terminate in the apartures 41,42 on the front of the housing 36 as ssan in Figure 1. In this context, the housing 36 may have a recessed reglon on its front, so that part of the housing ~ront i~ reces~ed at 43, tha apertures 41,42 being shown opening into this part 43.
Hole~ 44,45 are drilled in the housing 36 ~rom the . .
, ~5~
front, parallel to the regions of the second arms of the passages 39,40 and self-tapping, clamping screws 46 ara sarewed lnto these holes, so that the sarew heads clamp the aoras firmly relative to the slide 35.
Alternatively, however, clamping means of other designs can also be provided to clamp the cords I to IV. For example, levers with aams can be pivoted o~ the houslng, the cams of the levers clamping the cords firmly. This has the advantage that the cords can be released manually, without the use of tools.
~pproximately at the centre of the housing 36, at right angles to the profile 6, a general.ly T-shaped clamping member 47 is inserted in t~e housing 36. Ears 47a extending longitudinally and laterally from the member 47 engage the under side surfaaes of the inturned side pieces of the channel of profile 6, oppo6ed to the region 35~ of the housing. At its front, the clamping part 47 has a thread 48 on whlch i~ screwed a cap nut 49.
I~ this nut 49 is tightened, its lower surface engages a recessed surfaae 43 of the housing, and thus pulls the ears 47a of clamping member 47 outwardly so that the ears 47a o~ the clamping member 47 and the bottom part 3Sa clamp the inturned side pieces between them to look the slide 35 to the profile 6.
In this position, it may be aavantageous to release the alamping means 46 and to bring the cords I to IV
sufficiently far orward out of the slide 35 to enable them to be pulled manually, to move carxiage S slidably in the ~ide profiles 6 in order to ralse or lower the bottom rail 7 of the blind, which iB aarxied by the carriage S. Normal raislng or lowsrlng of the bottom rail 6 is achieved wlth the cords alamped by the screw :~
46, that i~, by raising or lowering the slide 35.
The clamping means 46 aan be temporarily slackened off and any looseness in the coxds I to IV can be removed .
, . . ..

by pulli.ng on the portion of the cords I to IV whiah extend to the front of the slide housing.
In the alternative, one can release or indeed remove the screws 46 and adjustment of the blind can be achieved S by pulling on the frae part of th~3 draw cords whlch extend to the front of the slida houæing. ~his could be done if, by some ahance, the slide houæing should become jammed, or if it were for some reason undesirabla to loosen the nut 49.
