Abstract
ABSTRACT OF THE DISCLOSURE
At least one connector for use in a window spacer assembly for spacing a pair of panes of glass to form an insulated glass panel. The assembly includes at least two elongated tubular spacers, each having a predetermined internal cross-sectional area and arranged to be secured together by the connector for dis-position between the panes. The connector is formed from a plastic and serves to connect the spacers together at a pre-determined angle, while enabling them to deviate readily from that angle without loosening the connection between the spacers to thereby facilitate the construction of the panel. The connector comprises a pair of legs connected at a junction at the predetermined angle and each of the legs includes a free end from which a single, curved resilient finger project backward and into the spacer to effect frictional engagement with the interior of the spacer by the leg, irrespective of manufacturing tolerances in the cross-sectional area of the interior of the spacer. The cross-sectional area of the junction is substantially smaller than the cross-sectional area of the interior of the spacer to enable the legs to flex from the predetermined angular orientation.

Description
f'~
SPECIFICATION
This invention relates generally to connectors and more particularly to connectors for use in the construction of insulated glass panels.
As is known, insulated glass panels include a pair of panes of glass slightly spaced from each other to create an insul-ating air space therebetween. It is a common practice in the production of such panels to utilize a spacer assembly disposed between the panels and within the panel-holding frame to maintain the panes at the proper spacing from each other. Such assemblies -~are composed of plural elongated spacers, which in the interest of weight reduction are hollow tubular members, and are held together by connectors in the overall shape of the periphery of the glass panel. To that end, the spacer connectors of the prior art common-ly include a pair of perpendicularly oriented legs, each leg being `
arranged to fit within the hollow interior of a respective spacer to effect the connection of the spacers at right angles to each other.
j Heretofore, spacer connectors have been constructed of a rigid and generally inflexible material, such as die-cast metal.
`` Such prior art spacers have several drawbacks which relate directly to the assembly of the panel. For example, due to the rigidity of prior art spacer connectors, such connectors may not fit snuggly .: , enough within the associated hollow interior of the spacer to hold `~
the spacer in place as the assembly is assembled. The loose fit ~
of the connectors is commonly the result of manufacturing tolerances -in the cross-sectional area of the interior of the spacer. In addition, the inflexibility of the connectors may result in ~heir ~ ~
slipping out of an associated spacer of the assembly should the `~ ;
normal angular orientation of the spacers with respect to each other be momentarily disturbed or otherwise varied as by being bumped or impacted as the glass panel is assembled.

Accordingly, it is a general object of this invention to provide a connector for use in insulated glass panel spacer assemblies which overcome the disadvantages of the prior art.
It is a urther object of this invention to provide a connector for securely connecting a pair of hollow spacers to each other, irrespective of the manufacturing tolerances in the cross-;~
sectional area of the interior of the spacers.
It is still a further object of this invention toprovide a connector for securely connecting a pair of spacers together at a predetermined angle, yet enabling the spacers to deviate therefrom without loosening the connection therebetween.
These and other objects of this invention are achieved by providing a connector for use with a pair of spacers to form a spacer assembly for an insulated glass panel. Each of the ~`~
spacers is an elongated tubular member having a predetermined internal cross-sectional area. The connector is adapted for connecting the spacers together at a predetermined angle while enabling them to deviate from the angle without loosening the connection between them. The connector comprises a pair of legs ' 20 connected at its junction at said predetermined angle. Each of 'i the legs includes a resilient finger projecting therefrom to effect ,~
- the frictional engagement of the interior of the spacer by the leg, irrespective of manufacturing tolerances in the cross-sectional area ,, of the interior of the spacer.

of the connector thereto and the concomitant securement of the ; spacers to each other via the connector.
The major portions o~ each side wall serves as a stop against which an associated pane of glass is held to effect the proper spacing of the glass. A conventional frame (not shown) serves to hold the glass panes and the interposed spacers in place.
The spacer 22 is formed from a flat metal s~rip, such as anodized aluminum, which is bent into tubular shape and in-cludes a longitudinal seam 42 running down the center of the inside wall 28. The seam is preferably serrated so that the spacer is enabled to "breath" to maintain a dry, even air balance within the insulated panel.
The details of the connector 20 of this invention are ` best seen in the perspective view of Fig. 3. As can be seen therein, connector 20 basically comprises a pair of legs 44 projecting at right angles to one another from a central portion or junction 46.
Each leg terminates at a rounded free end 43 having a resilient finger 50 projecting upwardly therefrom and curving backwards towards the junction. `
In accordance with the preferred embodiment of the invention, the junction, the legs projecting therefromt and the fingers projecting from the legs, are all formed as an integral unit from a rugged, yet relatively flexible material, such as Nylon. -As can be seen in Fig. 2, each leg 44 of the connector 20 is adapted for disposition within the interior of the spacer 20, with the leg of the connector disposed within the major portion 38 and the finger 50 disposed within the minor portion 40.
In accordance with the preferred embodiment of this invention, the distance between the top edge 52 of the spacer 20 and the bottom edge 54 of the leg to which it is connected is slightly greater than the maximum internal distance between the _ 5 -' ~ ,. .

Accordingly, the connector 20 can be firmly secured to a spacer 22 irrespective of variances in the dimensions of the interior spacer due to manufacturing tolerances. This feature enables the facile assembly of ~he spacer to one another since it eliminates 10 the delay caused by connectors falling out of the spacers or other-wise enabling the spacers to se~arate rom one another.
In accordance with another aspect of this invention the cross-sectional area of the junction 46 of the connector 20 is approximately the same as the cross-sectional area of each leg ~`

to be flexed relative to one another so as to deviate from their `
