COOPER 5 ADJUSTABLE LOUVRE SHUTTER 0R BLIND Filed Dec; 15, 1943 2 Sheets+Shet 2 Patented Jan. 4, 1949 ADJUSTABLE LOUVER SHUTTER on. BLIND Olifiord Edward Cooper, Newt/own, near Sydney, New South Wales, Australia Application December 15, 1943, Serial No. 514,412 In Australia December 22, 1942 This invention consists in a louvre shutter blind or the like which is mounted in an adjustable manner so that the angle of the louvre may be varied for the purpose of promoting ventilation and in some cases for providing blackout condidition, if desired. l

The present invention aims to provide a form of construction in which louvres or lathlike shutters are mounted in metal holders or end mom hers pivoted in a longitudinal manner and capable of being rocked or turned upon their re spective pivots .by a system of levers and a single operating :bar common to all of the louvres.

The present invention also relates to means carried by the metal holders or end members for the louvres, whereby access of wind and/or rain is prevented when the louvre or shutter is in the closed position. l r

Adjustable louvres are known,- but the present form of construction differs therefrom in that it is of easy manufacture at a relatively small cost, is capable of mass production and is quickly assembled. l u v i According to the present invention there are provided two stiles or metal fittingswhich are of channel or boxlike formationand consist ofa face portion and two flange portions one'of which is recessed, said channel fittingsxbeing ofslightl-y greater length than the sum of the widths of the louvres when closed.

Each louvre which may be of glass or other material is mounted at each end in a slotted or channeled end member or metal holder adapted to be secured as by a riveting action to a pivot ing member, the said m'ember'being formed with a bearing portion received in a hole in the we spective metal fittings and having a flanged por; tion which engages the inner lament the said fitting. The pivoting members are freely mounted in one of the said fittings so as to'turn" easily in the holes therein. l

Each of the pivoting members mounted in the other fitting have an arm extending therefrom, the said arm being either integral with the pivoting member or secured thereto.

The outer or free ends of the respective arms engage respective slots vformed in a common 'operating member which is housed 'within the said fittings and is movable therein ina truly longi tudinal manner by a suitable handle or lever or 3. Claims. (01.20-62) other means capable of imparting the said longitudinal movement in either direction of the said operating member.

The channeled end members or metal holders for the louvres are of a length substantially equal to the width of the louvre. The portion of each flange of the channel members on opposite sides thereof and at the ends thereof is cut away so that in the closed position of the louvres the latter lie closely face to face where they overlap one another, thus ensuring a Watertight and weathertight closingof the shutter. The metal holders have a turned over portion to retain the louvre in the channels.

It has been found that wind and rain will pass between the metal fitting which is secured to the usual mullions, and the respective metal holders for the louvres and therefore it has been found necessary to provide bridging means for preventing this taking place.

In :order to prevent ingress of wind and/or rain a bridging member is provided to bridge the space between the metal fitting and the channeled end members and is carried by the latter. The end members for the louvres each have a pro tecting strip disposed at right angles thereto and being formed either integral therewith or secured thereto in an approved manner. The bridging member is of channel section and adapted to receive the said protecting strip within it when the shutter is closed. In order that the bridging member may move in synchronism with the louvres the said member is pivotally con-- nected to the lower end of each of the protecting t strips of the metal louvre holders.

To provide the protecting strip for each louvre end member the said end member may be formed from a single sheet of metal bent or pressed to form a channel section with the protecting strip formed as a web at right angles to one side of the channel.

For instance commencing with the protecting strip portion there is a flange portion at right angles thereto formed of a double thickness of folded metal, then a base at right angles thereto, and finally another flange portion at right angles to the said base and parallel with the first double web portion. Viewed in section the louvre holder comprises for example, a vertical protectmg strip, a vertical base for the channel and two horizontal flange portions for the channel between which the louvre is fitted, the said horizontal flange portion adjacent to the said protecting strip being doubled upon itself to form two thicknesses of the metal. If it is not desired to form the above double folded portion, the protecting strip may be formed from right angle section material welded or otherwise secured to the louvre holder.

In assembling the invention the respective pivoting members are placed in their respective holes in the metal fittings and each has a rectangular projection which is passed through a slot in the respective end members and is riveted over or welded to retain it in operative relation with respect to the stile. The glass or other louvres are then placed in the respective channeled end members.

In order that the invention may be more readily understood, reference will now be made to the accompanying drawings wherein:

Figure 1 is a perspective view illustrating one end of a louvre blind or shutter made in accordance with the present invention and illustrating the attachment of a bridging member to the end channel members.

Figure 2 is an elevational view looking towards the inside of one of the metal fittings and showing the operating arms of the pivoting means for the respective louvres and the longitudinally movable member which moves in conjunction therewith.

Figure 3 is a detail view in closed position illustrating in sectional plan the bridging member, its pivotal attachment to a channel end member, the pivoting means for the latter and the functional relation of the bridging member to the recessed flange of the metal fitting.

A pair of metal fittings it of channel formation and consisting of a face portion and two flange portions one of which is recessed, is provided for each set of louvre shutters, each of said fittings being secured to the usual mullions I l and together form a housing within which pivoting and operating means for the louvres are received. At suitable distances apart holes are drilled in the metal fittings H] to receive the bearing portion I2 of the pivoting members for the channelled end members l3 which support the louvres The pivoting members have a flanged portion I5, see Figure 3, which engages the inner face of the respective metal fittings I0, the said pivoting members also being secured to the channelled end members I3 by means of a turned over or riveted portion [6 which has been passed through a slot or hole formed in the end member for this purpose.

Each of the pivoting members disposed in one of the said metal fittings ID has an arm l1 extending therefrom the outer end of which has a pivot I8 adapted to engage a transverse slot l9 formed in a longitudinall movable operating member 20, see Figures 2 and 3. The said operating member 20 has an operating arm 2| or other suitable means for moving the said member 20 in a truly longitudinal manner within the said fitting.

The channelled end members l3 as illustrated are formed from one piece of metal pressed to the desired shape, for forming a protecting strip at right angles thereto.

The said end members l3 illustrated are channelled to receive the louvre l4 and'are formed with lips 23. Portion of each flange 24 of the channelled end members l3 on opposite sides thereof is cut away at 25 so that in the closed position of the louvres Hi the latter lie closely face to face where they overlap one another thus ensuring a, watertight and weathertight closing of the shutter when in the closed position seen in Figure 3.

A bridging member 26 of channel shape and having two flanges is provided to bridge the space between the metal fittings I0 and the channelled end*members I3 in their closed position. This bridging member 26 is secured by a pin 2'! and slot 28 form of connection to the protecting strip 29 of the said end member I3, the said strip being either integral with the end member I3 or attached thereto.

As illustrated the channelled end members I3 are formed from a single sheet of metal bent or pressed to form a channel section with the two flanges 24, and a protecting strip 25 attached thereto.

When in the closed position the bridging member '26 bridges the protecting strip 29 by means of its two flanges, one of which is pivotally connected to the respective protecting strips while the other flange enters the recess provided in the respective web of the metal fitting I0 provided to receive it.
