2 Claims. c1. -565 The present invention relates generally to improve:

ments in windows and more particularly to improve-;

between the glass sheets. Such glazing units have been.

found to be particularly effective in diminishing heat loss from buildings in cold climates and likewise to be effective when it is desired to maintain a cooler temperature within buildings than prevails outside. However, it has been found in modern building structures,

where it is the general practice to employ rather large expanses of glass and wherein it is rather impractical to provide shading devices, such as roof overhangs, hedges, etc., that during those periods of the year when the sun is at a low angle relative to the horizon, a substantial amount of radiation into the building through the glazing units occurs and in some instances the radiation is suffi' cient to increase the temperature inside of the buildings to the point of extreme .uncomfortableness. To avoid this undesirable phenomenon the glazing units are usually shaded in some way or another, such as by awnings or canopys, for example.

The inherent drawback to multiple glazing units when used in modern buildings having such largeexpanses of light admitting areas, as mentioned above, has already been recognized and it has been proposed to mount a shade screen, such as is shown in the patent to Ewing, 2,194,222 between the two spacedparallel sheets of glass. Various means for mounting such shade screen between the glass sheets have been proposed but heretofore none of these mounting means has proved to be particularly effective or economical.

The principal object of the present invention is, therefore, to provide an improved means for mounting shade screen of the type disclosed in the aforementioned patent to Ewing 2,194,222, between two parallel panes of glass .in such a manner that all of the desirable features of sealed multiple glazing units are retained and the shade screen is held in position between the glass panels bymeans which render the overall assembly of the unit.

Fig. 4 is a fragmentary view, shown in section, further illustrating the corner construction and;

Fig. 5 is a view illustrating the retainer means utilized to hold the screen in a taut condition between the op posed frame members of the glazing units.

With reference to the drawings, wherein like reference numerals have been utilized to identify identical parts in each of the several views, there is shown in saidfigures a combined window and screen glazing unit illustrated generally by reference numeral 10. The glazing unit comprises two parallel sheets of

glass

11 and 12 and a piece of shade screen 13 which are mounted in parallel relation with respect to each other by suitable framing devices indicated generally by reference numeral 14.

The framing devices 14 together form a substantially.

rectangular frame of suitablesize and each comprises an extruded member 15 which is preferably made of aluminum. The extruded aluminum frame members 15 are each formed with a recess or channel 16 therein which is defined by a pair of facing

projections

17 and 18.'

The projecting

portions

17 and 18 are respectively provided with

shoulders

19 and 20 and the projecting

portions

17 and 18 are disposed a sufiicient distance apart to accommodate the screen 13.

The frame members 15 are also each formed with opposed flat surfaces 21 and 22 which lie in planes substan-.

tially parallel to the panes of

glass

11 and 12 and with outwardly projecting

abutment shoulders

23 and 24. The

panes of

glass

11 and 12, whenfassembled with the framing members 15, are respectively disposed against the fiat surfaces 21 and 22 and with their marginal edges respectively seated against

shoulders

23 and 24.

It is contemplated, if desired, that a suitable sealing mastic may be disposed between the glass panes and the Surfaces on the framing members 15 and, in order simple and economical and which means provide a quality product.

Other objects and advantages of the present invention will become apparent from the following detailed description thereof, when taken in conjunction with the accompanying drawings, wherein:

Fig. 1 is a view illustrating a glazing unit of the general type to which the present invention is particularly applicable;

Fig. 2 is a sectional view taken substantially along the line 2-2 of Fig. l and illustrating the structural details of the mounting means comprising the subject matter of the present invention;

Fig. 3 is an enlarged fragmentary view, partially cut away showing the construction of a corner of the combined glass and screen glazing units;

to retain the

glass panes

11 and 12 in assembly with the framing members 15, suitable U-shaped enclosing members 25, which may be formed of any desired suitable material, are provided which have

side portions

26 and 27 respectively adapted to hold the panes of

glass

11 and 12 rigidly against the framing members 15.

The framing members 15, at each corner of the glazing unit 10, are mitered so as to provide neat corners for the assembly and are joined together by suitable L- shaped members 28 which fit snugly within the chan-v nels or openings 16 in theadjacent framing members 15 in order to hold the framing members in assembly with each other.

The mounting means of the present invention is particularly adapted to retain the top and bottom edges of the screen 13 under the desired tension between and in assembly with the top and bottom framing members 15. The screen 13 may be of any desired type capable of cutting out a certain portion of the light which otherwise would be transmitted through the glazing unit, and, in

the present case, the screen is shown as screening material of the type shown in the patent to Ewing 2,194,222.

This type of screen comprises longitudinally extending parallel ribbon-like filler or louver wires.29 which are vers wires 29 and this provides a certain amount of longitudinal resilience to the screen while, at the same time, maintaining the desired angular relationship between the major surfaces of the ribbon-like filler or louver wires 29 and the plane of the screen when the screen is placed under tension between the framing members 15, respectively disposed at the top and bottom of the glazing unit 10.

The edges of the screen 13 are each' disposed Within Patented Feb. 24, 19591 the chanriel-16- ofrthe respective framing members 15; however, only the top and-bottom edges or end portions of the screen 13 are positively retained within the channels 16.

The means for positivelyretaining the top' and bottom end portionsof-the 's'creen1-3 within the channels 16'of the top and.bottorn framingmembers 15will now be described. Thisfmeans comprises a sinuous lacer-like retainer element. or member 31. The sinuous lacerlike retainerelement 31 is preferably made of some desirablelmetallic"wire formed into a sinuous shape in any desired manner, such as, by running the'wire through a pair vof gears to provide elongated portions 32 alternately'spaced between uniformlyspaced 'crest portions 33; The spacerbetween each adjac'ent pair of crests 33' isfsubstantially equal to -the space between each adjacent set ofL'warp wires 30 and it is contemplated that the; laser-like retainer -member 31 ma'y be" assembled with the top and bottom end portions of the screen'13 byinierely pushing the retainer-element 31"bet'w'een" an adjacent'paifof louver wires'29near the top and bot tom e'nds of-the screen 13in a manner such that each p'airof warp wires 30 is received within one'of the crests 33. It will be noted that the depth of each of the crests 33 is, of the order of two to three times the width of each louver or filler wire 29 so that when the lacer-like retainer 31 is assembled with the end portion of the screen 13, as shown in Fig. 2, the substantially straight portions 32 which join the crests 33 are disposed on one side of thescreen 13 while the peaks of the crests'are disposed substantially the' same distance from and on the opposite side .of the screen. The straight portions 32 and. crests 33 then respectively engage the shoulders 19' and 20' on the projections 17 and 1S and thus positively prevent the withdrawal of the screen 13 from the channel 16, inan upward direction, as viewed in Fig. 2. i

It will be understood that the upper end portion of the screen 13 will be assembled with the top frame member. 15 inprecisely the same manner as the lower end of,the.screen 13, may be inserted'into the channels 16- through-the ends'of-the channels 16; The side fra'rne memberslS may thenbe assembled, these being securedto. the top and bottom end frame members by the L- shapedacorner brackets.28. Thereafter, the panes of

glass

11 and 12 are suitably positioned and the sealing member'15.ismounted around the entire frame in order tofhold ftheentire assembly together.

It will be understood-that the screen 13 may be positioned within the top and bottom frame members 15 and thereafter these. frame members can be spread apart slightly to .provide the desired tension for the screen 13. It.will--also be understood that the ends of the louver or filler wires 29 will be disposed between the projections 17 and 18of the side frame members 15,'it being unnecsary to provide any positive retention for the side edges of-the screen'within the channels of the side frame membersIS.

It'will be further understood that the corner members- 28,-are; adapted to fit snugly within the channels 16';

4 fications may be made in the present invention without departing from the spirit or scope thereof.
