Dec. 6, E POILLARD AWNING Filed Dec. 3. 1931 INVBNTOR Harold B. Pollard ATTORNEY Patented Dec. 6, 1932 UNITED STATES HAROLD EDWARD P OLLARD, OF LONDON, ENGLAND, less'ronon To, nronnnnn COMPANY LIMITED, or nonnonfinnenann nwnnve V Application file d December a, 1931, Serial No.

This invention relates primarily to, window blinds of the awning type, but is applicable to sunshades or Weather shades for purposes other than for the protection of i g p I lath'at thefreeend of asun-blind-or the like; 5 1 ,The rail A is supported at or neareach end T 5 windows. y

In such apparatus the rail or lath at the free end of a sun-blind or the like is supported at each end by anarm which is made in two parts of substantially equallengths pivctally connected with each other, the ends of the lath or rail being supported at the end of the outer half. The other or inner half of each arm is pivoted at its inner end to permit it to be swung backwards, as for'example, inwardlyr Ieans are provided whereby the outer half of the arm is swung backwardly upon its pivot when the inner half of the arm is swung upon its pivot, so that the outer part of the arm is, as it were, folded against the inner part when the latter is swung back wards to the closed position for the sunblind. V V

This result is attained according to the presentinvention byproviding a longitudinal guide on the inner half of the arm in i which a sliding rack is movable, the rack en gaging a pinion fast on the inner end of the outer part of the-arm and pivoted on the guide, this pivot forming the pivotal connection between the two parts of thearm. The sliding rack is actuated by means of a radius rod connected at one end therewith and pivoted at its other end at a point suit ably displaced from the pivot axis of the inner part of the arm. When the latter is swung inwardly upon its pivot," the rack is pushed outwardly relatively to its guide and the pinion and rotates the latter upon its pivot, thereby swinging the outer part of the supporting arm so thatit folds backwardly along the inner part thereof. 7 y

In the accompanying drawing Fig. 1 is a plan showing one end of a sun-blind support in accordance with the present inven tion, with the top of the box or casing removed, and Fig. 2 is a transverse section 7 through the box on line 22 of Fig. 1. In these figures the supporting arms are shown in full lines asfolded up within the box or 578.826, and in Great BritainMa'rch 2a; 1931;

the blind is? rolled up, andin; dotted lines as partially extended or unfoldedQ I L In these drawings A represents vthe railor by'a pivoted or jointed, arm, the outer part B of each arm beingconnected'with thellath at a convenient point along its length, as for example atfB, bymeans of a pin and slot v connection; The inner end of the outerhalf B is pivotally connected :with theginner half C of the folding arm as at the point C near its outeriend. The inner end of the part C ofthe folding arm'is' pivoted to a bracketr D .65 V withinthe fixed;box or casingE, aslat the point D, so as to enable it to be swung in-.

.wardly into the position shown in full lines I -V in Fig. 1. The outer end of the inner part C 7' r of the folding arm is formed as or has securedflq to it a guide C in which a rack F is arranged to slide; This-rack F engages a pinion B formed on'or secured to the inner end ofithe outer part B of the folding arm, and it is pivotally connected with the outer end of a radius rod G, the inner end of which is pivoted as'at G within the box or casing and V has an extension in the form of a segmental worm wheel G which engages a worm H uponan actuating shaft I. I H f When the inner part G of the folding arm is swung inwardly upon its pivot D, the' rack F is pushed outwardly relatively toitjs' guide C", thereby rotating the pinionB and causing the outer part B to swing upon the pivot C, so that the arm folds backwardly. 1 under the inner porting arm. l

Having thus described the nature of the" r i said invention and the best means I know ofmeans comprising a rack upon the inner part 9 i part C of the folding supof the arm, a pinion upon the inner end of the outer part of the arm and en aging'said rack, means for maintaining sai pinion in engagement with said rack during relative v 5 movement of said rack with respect to said pinion,;j and means for producing relative movement between said piniona'nd rack, said last-named means comprising a radius rod haying its outer, end pivotall andslidably connected withthatpoi'tion .0 "the innerpa'rt of the arm on which saidra'ck is formed and having its inner end pivoted on a fixed point, and means for swinging said radiiis" I rod about its, inner pivot." a. c 2.
