Abstract
Elbows in tubular blanks which are filled with a desiccant are formed by clamping a blank at one side of the intended locus of the elbow, by bending the blank at the other side of the intended locus of the elbow relative to the clamped portion of the blank, by propping the blank in the region of the inner wall of the developing elbow, and by plasticizing the material of the blank in the region of the outer wall of the developing elbow so that the material of such outer wall is less likely to exhibit cracks and/or to burst as a result of bending of the blank.
Claims16
A spacer for use in multiple-pane windows or the like, comprising an elongated member including an elbow and two sections flanking said elbow, said member having a tubular portion, a supply of desiccant at least partially filling said tubular portion, and two extensions extending laterally of said tubular portion, disposed in two substantially parallel planes and being spaced apart from one another, said extensions having outer sides which are adjacent the inner sides of two spaced-apart panes when the spacer is installed in a multiple-pane window and said tubular portion including two sidewalls having outer sides, the distance between the outer sides of said sidewalls being less than the distance between the outer sides of said extensions and each of said sidewalls being adjacent one of said planes and being integral with the respective extension.
A spacer for use in multiple-pane windows or the like, comprising an elongated member including an elbow and two sections flanking said elbow, said member having a tubular portion, a supply of desiccant at least partially filling said tubular portion, and two extensions extending laterally of said tubular portion and being spaced apart from one another, said extensions having outer sides and said tubular portion including two sidewalls having outer sides each adjacent the outer side of one of said extensions, the distance between the outer sides of said sidewalls being less than the distance between the outer sides of said extensions and each of said sidewalls being integral with one of said extensions, each of said extensions having a bevelled end face remote from said tubular portion, said bevelled end faces making an angle of less than 180 degrees and being inclined inwardly toward said tubular portion.
A spacer for use in pultiple-pane windows or the like, comprising an elongated member including an elbow and two sections flanking said elbow, said member having a tubular portion, a supply of desiccant at least partially filling said tubular portion, and two extensions extending laterally of said tubular portion and being spaced apart from one another, said extensions having outer sides and said tubular portion including two sidewalls having outer sides, the distance between the outer sides of said sidewalls being less than the distance between the outer sides of said extension and the outer side of each of said sidewalls being adjacent the outer side of one of said extensions, each of said sidewalls being integral with one of said extensions;
- and layers of sealing compound provided on the outer sides of said extensions to sealingly contact the respective panes when the spacer is inserted between the marginal portions of two panes.
A spacer for use in multiple-pane windows or the like, comprising an elongated member including an elbow and two sections flanking said elbow, said member having a tubular portion, a supply of desiccant at least partially filling said tubular portion, and two extensions extending laterally of said tubular portion, disposed in two substantially parallel planes and being spaced apart from one another, said extensions having outer sides which are adjacent the inner sides of two spaced-apart panes when the spacer is installed in a multiple-pane window and said tubular portion including two sidewalls having outer sides, the distance between the outer sides of said sidewalls being less that the distance between the outer sides of said extensions and each of said sidewalls being integral with one of said extensions, said tubular portion further including a plurality of longitudinally extending walls including an outer wall whose thickness exceeds the thickness of the remaining walls of said tubular portion, at least in the regions of said sections, said outer wall extending transversely of said extensions and said sidewalls.
A spacer for use in multiple-pane windows or the like, comprising an elongated member including an elbow and two sections flanking said elbow, said member having a tubular portion, a supply of desiccant at least partially filling said tubular portion, and two extensions extending laterally of said tubular portion, disposed in two substantially parallel planes and being spaced apart from one another, said extensioins having outer sides which are adjacent the inner sides of two spaced-apart panes when the spacer is installed in a multiple-pane window and said tubular portion including two sidewalls having outer sides, the distance between the outer side of said sidewalls being less than the distance between the outer sides of said extensions and each of said sidewalls being integral with one of said extensions, said tubular portion further including an elongated inner wall having an outer side provided with at least one longitudinally extending projection, said inner wall extending transversely of said extensions and said sidewalls.
A spacer for use in multiple-pane windows or the like, comprising an elongated member including an elbow and two sections flanking said elbow, said member having a tubular portion, a supply of desiccant at least partially filling said tubular portion, and two extensions extending laterally of said tubular portion, disposed in two substantially parallel planes and being spaced apart from one another, said extensions having outer sides which are adjacent the inner sides of two spaced-apart panes when the spacer is installed in a multiple-pane window and said tubular portion including two sidewalls having outer sides, the distance between the outer sides of said sidewalls being less than the distance between the outer sides of said extensions and each of said sidewalls being integral with one of said extensions, said tubular portion further including an inner wall and an outer wall, at least a portion of at least one of said inner and outer walls having an arcuate shape.
