noBER'rWooD, or cnnis'rcnnnon, NEW ,ZEALAND` Application 'iednecember 7 192s, sei-iai No. 324,538, and in New-zealand Dewinter 9,1927; v

This Ainvention relates to blinds as used 3 for screening windows or balconies and consisting of a strip of fabric attachedA at its upper end to ajroller, usually of the springcontrolled type7 and upon which such strip is adapted to wind and unwind.'

It is'well recognized that a blind of this nature when drawn completely down behind an open Window or other opening, tends to prevent the free passage of air with the result that insuilicient ventilation is obtained and the blind is aptto flap ,andk so cause annoyance. v v

It is the object of the present invention however to provide a blind of this nature of novel and special construction whereby the saine may be opened at its intermediate part, thereby overcoming the above mentioned objectionable features and permitting a certain amount of light to enter without exposing the room or other place behind such blind. v

ln carrying this-object into effect, accord- -ing to the present invention the blind is divided 'transversely into two portions the kupper of which is attached to the roller,

while the other or lower portion is adjustably connected to suoli upper portion by means of vertically arranged straps the bight portions of which are passed through to make running connection with eye-formations carried by the said upper portion, thereby permitting of the lower portion depending continuously with the upper portion or at any desired interval therebelow.

In order that the nature of the invention and its construction may be clearly understood, it will now be fully described and explained with reference to the accompanying drawings, in which:- y

F ig. l.-is a perspective view of a blind in accordance with the present invention y the same being shown in the closed condition, and,

Fig. 2.- is a similar view showing the blind in a partly open condition.

vl-is here shown l is a roller which may be of the lspring-controlled or other type and vsuitably mounted, as by means of brackets 2.

According` to the present invention the blind is dividedtransversely into two portions, namelyan upper portion 3 adapted for attachment to the roller 1 and a-lower portion 4 adj ustably connected ,to they upper portion 3- topermit of its dependinggeontinuously with the latter or at anydesired interval therefrom. j

,This adjustability is attained by the-einployment of vertically vdisposed straps 5. each having one of its ends connected with thenpper end of the lowerportion 4, as at 6 while kthegdoight portions of such straps arepassed through, to make running connection,w-itheyeformations carriedby the upperportion of the blind., y In jthe preferred form of the construction, as here shown,i the loweredge of the upper p'ortiony will beprovided witha stiffening wire 7 ,preferably contained within a seam as 8 which is out away at the required'points `to permit of thev straps being passed around such wire which thereforeY constitutes the laforenientioned eye-formations. ,j In a similar manner the r`Lipper endVV of the lower-portion 4 is preferably provided with a stilfening wire 9 preferably contained with aseam ,as lO-which'is also preferably cut awaylattheirequired points to permit ofthe running yparts of straps being passedy between such wire and the portion4 of the blind, by which arrangement the said straps will beineatly guided in position and asuitable vvdegree {offfriction occasioned to such straps enabling them to maintain the lower portion 4.of the blind atl anyvheight towhicli it may be adjusted in relation to the upper portion 3, as, hereinafter explained,

Inthe preferred form of the construction also the straps vare attached as at l1 to the lower Vendl of the, lower portion 4 of the blind, jsuchattachment occurring either, at n the opposite ends ofthe straps to those connected to the top portions Y 4, or as Vhere shown, 'at suitable intervals from such 4ends thereby. allowing.A` o f 'portions of suehstraps ifi ` stiiening the edge of the blind, there l i is preferably provided an elongatedlink 12 )of vmetal or `other suitablematerialf Vand c through which the lower endY of the portion n 41 of the blind Y'is passed ashere vshown,to `permit of such portion running'V freely v`through thegsaidflink which will i depend vfrom the."'lowermost Vpoint VVof the said j' portion.

j In order tof.` give amore finished appearance Va flapv as linay-beiprovided to depend fromthe lower side of theV link 12 and in cases where portions of the straps extend belowtheir-Pointed attachment 1l, as here shown, such lowervfportions ofthe straps willr preferably be passed throughrth'elink.

` ,inorder-toholdV them neatly4 in place.

In operation, the blind, when in its closed "condition with its portions and` 4 extending continuously, as in Fig. 1, will act as a y blind of 1 the ordinary` form,v and may Abe caused ,to windfor `unwind upon the roller inthe customary manner.

when Openingofihe bund is esima the portion is grasped and 4'drawn downward thereby drawingthe straps in one direction through the leye -`formations, and so placing the upper edgeofthe portion 4; at an interval j beneaththe lower `edge ofthe portion 3, in

some such position asthat shown in Fig. 2.
