Description
2 2~7~7~
BAC~GROUND OF THE INVENTION
The present invention relates to a packet blind assembly including means for quickly dis-engaging the blind sheet.
There are already known packet blinds, that is blinds in which the blind sheet is slidably ver-tically moved and stored at the top of the blind as a"packet", in which the blind sheet comprises a plurality of slits or buttonholes which are mutual-ly aligned and arranged at a given spacing from one other, so as to operate as guiding elements for guiding the blind sheet driving cords to allow the sheet to be properly folded in a raised condition thereof.
For washing the blind sheet, the latter is conventionally disengaged by removing the cord guide slits from a shaped section member supporting the blind assembly.
A drawback of such a construction is that also the guide slits or buttonholes are washed to-gether with the blind sheet.
SUMMARY OF THE INVENTION
Accordingly, the aim of the present inven-tion is to solve the above mentioned problem, by pro-3 2~7~7~
viding a packet blind assembly, including means forquickly removing the blind sheet which, in addition to allowing a proper folding of the blind sheet, also provides the possibility of quickly and easily removing the blind sheet while holding the blind sheet guide elements anchored to the blind construc-tion.
Within the scope of the above mentioned aim, a main object of the present invention is to provide such a packet blind which can be easily and quickly assembled and disassembled even by unskilled operators.
Another object of the present invention is to provide a packet blind assembly with built-in means for quickly removing the blind sheet which is very reliable in operation, can be made starting from available elements and materials and which, more-over, is very competitive from a mere economic stand-point.
According to one aspect of the present in-vention, the above mentioned aim and objects, as well as yet other objects, which will become more apparent hereinafter, are achieved by a packet blind assembly comprising a blind sheet including a plura-4 2~7~7~a lity of driving cords which are slidably engagedwith said sheet at evenly spaced points and with transmission elements associated with a section mem-ber supporting said packet blind, characterized in that said trasmission elements comprise disengagement means for disengaging the cords from said transmis-sion elements, with the cords associated with the sheet.

DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference to the figures of the accom-panying drawings, the packet blind assembly accord-ing to the present invention, which has been general-ly indicated at the reference number 1, comprises a blind sheet 2 provided with horizontal folding lines 3.
With the blind sheet there are engaged driving cords, and, more specifically, these cords are engaged both at the longitudinal edges of the sheet and at intermediate portions thereof, said cords being adapted to slide through slits or button-holes provided through the blind sheet at vertically spaced p~ints and advantageously corresponding to the mentioned horizontal folding lines 3.
At the top edge portion of the blind sheet 2 there is provided a tear strip portion, generally 2~7~7S~
inclicated at the reference number lS, which engages wit:h a corresponding tear strip portion 16, joined to the front face of the section member 17 whicn con-stitutes the supporting element for the blind assem-bly.
At the top end portion of the blind sheet, the cords engage with transmission elements, includ-ing intermediate or middle transmission elements, generally indicated at the reference number 20 and which are better shown in Figures 3 and 4.
These intermediate transmission elements 20 are provided with a top sliding pad 21, which engages in a corresponding channel of the section member 17 and being arranged on the top of a fork shaped body including a front portion 22 and a rear portion 23 which are joined by a pin element thereon there is rotatably engaged a roll 25 operating as a sliding element for the cord.
A main feature of the present in~ention is that the intermediate transmission elements are pro-vided with means for disengaging the cord 10, includ-ing slots 26 arranged between the rear leg or portion 23 and the sliding pad 21, so as to allow the cord 10 to be easily engaged and disengaged, the cord be-.`~` 2~707~a ing held connected to the blind sheet.
The several driving cords are mutually con-nected at a respective side end portion thereof, where there is provided a side transmission element, generally indicated at the reference number 30 and including a body 31 having a coupling top pad 32.
To the body 31 there is removably connected a closure~cover element 33.
The body 31 supports a pair of transmission rollers 34, therethrough the cord assembly connected to the frame is caused to pass.
Under the transmission rollers there is ar-ranged a locking roll 36, which is floatably mounted in order to affix the cords so as to prevent the packet blind from undesirably lowering.
The cover element 33 comprises a locking element 37 engaging in a slot provided on the body 31 in order to removably connect the cover element 33 and allow the cover element 33 to be easily re-moved so as to provide the possibility of disengaging the cords 10 from the transmission rollers 34 with-out removing said driving cords from the blind sheet.
This feature is very important since it allows the blind sheet to be washed without removing 8 2~7~
the cords from the transmission elements, and this by means of operations which are very simple and quick.
While the invention has been disclosed and illustrated with reference to a preferred embodiment thereof, it should be apparent that the disclosed embodiment is susceptible to several modifications and variations all of which will come within the spirit and scope of the appended claims.
