Abstract
ABSTRACT OF THE DISCLOSURE
A spacer bar, suitable for use in a window, unit includes a further wall wrapped over an inner spacing wall between the panes of glass. The further wall is provided with upstanding tabs stamped or cut from the further wall for sup-porting muntin bars or parallel ridges to hold the edge of an extra pane of glass.

Description
~rhis irlvf~ ;.O~l r(~ e~; I,o ~ .r~ J1,1~,e~ tI:it ar1~'l to a spacer b~r for sl)acir1~ apart the g1clss panes of such a, unit.
In Iml]tip1e g1aze~c1 unlts two or rnore panes o~ glass are ncrmally ~space(-1 one Erom another by m;lrginal edye .spacers and adhered thereto by a sealin~ composltion applied be-tween each pane and the spacer~ ~le spacer is often a 'hollow vented profiLe section and may contaln dessicant to avoid condensa-tion between the sealed glass panes.
When -the spacer is a profile sectionI e.g. a tube, it is frequently roll-formed or extrucled. It may have a pair of side walls, an outer wall and an inner wall. The inner wall may define the greatest span between the side walls and the glass panes. ~he outer wall which lies flush with the edges of the glass panes may have a sornewhat narrower span.
Thus the side walls extencling be-tween the inner and outer walls do no-t define maximuIn span over t'heir whole heiyht.
Sealing compound is located in wha-tever space is available between the glass panes and the side walls.
When more than two panes of glass are used in a multiple glazing unit it is quite coImnon lnerel~ to a'but a second spacer -to one pane of a c1Ouble glaz,ed unl-t and provide another pane of glass to the free side o~ the secor1d spacer.
When Inuntin bars are used betweel1 t,he panes for decorative or reinforcement purposes lt 'has been a problem -to 2S fix them securely to the spacers so thc~-t there is no danger of them slipping out oE position due, for example, -to vibration.
I-t is therefore an object of -the invention to provide an improved spacer for a multiple glazed unit.

Accordi.ng to the invention there is provided a spacer suitable for ~use in a window unit having at least first and second parallel and spaced-apart panes of glass, the spacer being a hollow tubular member positionable between the firsk and second panes of glass and comprising:
a pair of side walls;
an outer wall interconnectin~ the inner walls; and a pair of inner walls substantially parallel to said outer wall, one of said inner walls extending ~ver the length of the tubular member and the other of said inner walls being wrapped over said one inner wall and ex-tending over the len~th of the tubular member and between the side walls.
The wrapped over other inner wall privides a support from which can be cut or stamped mounting means, for e~ample, I
upstanding tabs, indentations, ridges, bumps, or apertures.
These mounting means may be used for mounting any desired material between the window panes, notably, a further glass pane or muntin bars. The tubular member may be made :erom metal, for example aluminum, or may be made from a -thermo-plastic material.
Embodiments of the invention will now be described,by way of example, with reference to the accompanying drawings of which:
Figure 1 is a perspective view of ~ par-t of a con-ventional spacer sandwiched between two glass panes, Figure 2 is a perspective view of part of a spaceraccording to the invention;
Figure 3 is a perspeGtive view of part of a spacer similar to that of Figure 2 having mounting means for muntin bars and a third glass pane;

Fig. 1 of the drawings il.lustrates a conven-tional hollow vented s~acer 11 comprising a rol.1 formed metal tube located between i.rst and second glclss panes 12 and 13 as in a conventional sealed uni-t. The inner wall 14 spans the gap between the glass panes 12, 13, and is forrlled as two interlocking parts with an air gap therebetween as shown.
The outer wall 15 has a span less than the lnner wall. The side walls each have two parallel port.ions 16, 17 joi.ned through a shoul.der 18. Near the outer rnaryins o:E the glass pa.nes 12, 13, .æpaces 19 are~ def.itlecl betweerl khe g].ass, sid~
wall portions 16 and shoulcler 19 for fil.l:irlcJ with sealing ~ ~2s;CC~ ~ t compound. ~esshsT~t~ is usually placed within the hollow interior of the spacer 11.
In the remalning Eigures il].us-trating -the invention, the same reference nurnerals as those of Fig.
are used to desigrlate similar parts. A spacer 20 is made by roll-forming longit.udinally a longitudinal strip into the shape illustrated as, for example, in Figs. 9, 10 and 11.
The material from which the spacer is formed is conveniently metal, e.g. alumi.num, or rigid thermoplast:;.c, for example polycarbonate. Tlle inner wall :is formed by a ~irst substantia].ly flat portion 21 subs-tantialLy spanning the de~ire(l ~ l,e~ r~ (~L,~ r.ZL~p~ ver ~ rld ortiorl 22 l.:i.es over E;.:rst ~?o~tion 2.1.
IE no mllnt;.~ ar.s or ext.rcl patles o.~ glass or any other item is to be Located betweell the fi.rst and second 5 glass pan~s located on eacll sicle oE the spacer, then the second wrapped ~ver intler wa~l portion 22 oE the spacer may be free from addit.ional. mounting means.
Inner wall por-t,ion 22 is advantageously provided, as seen in Figs. 3 and 6, with a pair of paralleL ridges 23 running longitudi.nal.l.y al.ong its length and projecting inwardly. The ridges 23 are spaced apar-t -to accept the edge of a further pane or glass therebetweenO
In Fig. 6, a third glass pane 26 is shown mounted between ridges 23. ~le ri.dges may be formed on the por-tion 22 before the strip is roll-forme~ .in-to the form of -the spacer 20 or afterwards, or as part o~ the spacer forming operation.
Inner wall por-tion 22 may be easil.y provided with mounting means for muntin bars or r~i.rl.Eorc.i.ng bars or other material lt is desired to :I.ocate between the panes. Wrapped over port.ion 22 ,is ava:iLable t,o simple cutting and tooling devices after forrnat.].on of the s-trip into the spacer 20.
Tabs 24 may be cu-t or stamped from the portion 22 and bent into an upstanding position to act as latches with the interior of ends of hollow muntin bars 25. Alt:erna-tively, a series of four tabs can be cut or stamped from portion 22 and bent to be upstanding thererom and to .Eorm a box 27 -to hold -t~e end of a so1id or hollow mun-tin or reinforcing bar. The tabs may be of any convenient shape and pattern.
Al.ternatively to stamping or cutting tabs from the portion 22, indentations or raised portions can be provided.

Figs. 7 an-l 8 show other instances oE a third pane of glass 26 mounted between panes 12 ancl 13 u~sinc3 alternative embodiments of ~he inventive spacer bar. The spacer bar of Fig. 7 has, in place of ridges 23, a trough 40 which is formed in overlapping wall portion 22. Trough 40 receives the edge of third glass pane 26. Wall portion 22'has a portion 44 bent back underneath trough 40 providing some support for trougll 40. In the spacer bar :illustra-ted, still further support i5 provided by a leg 38 bent at right angles from inner wal.l. portion 21 extendlng towards outer wall 15.
The spacer bar oE Fig. 8 is similar to that oE
Fig. 7 in that it is provided with tro~lgh 40. Uowever, in this case, wall portion 21 is sim:ilarly formed so that trough portions of wall portions 21, 22 coincide to form -trough 40.
Dessicant 42 Eills the space within the spacer bar and 'has a drying effect on the region betweerl panes 12, 13 throug'h the crack between wall por-tions 21 ancl 22 and through t'he 'ho'l.es G/e S 1~ C ~ r,,~ ~

The third sheet of glass 26 is located in position during assemhly. First and second panes of glass 12 and 13 are positioned one to each side oE the spacer 20 and sealing compound 29 is compressed in-to spaces 19 and on the outer wall 15 of the spacer between glass panes 12 and 13.
The fina]ly assernbled unit can be mounted conventionally in a frame.
