Abstract
Spacers/spacer frame assemblies for use in insulating glass units that include offset seams and methods of using and manufacturing the same are described herein.
Claims59
An insulating glass unit comprising:
- a first pane comprising an interior surface and an exterior surface;
- a second pane comprising an interior surface facing the interior surface of the first pane and an exterior surface facing away from the first pane;
- and
- a spacer located between the first and second panes, wherein the spacer extends from a first end to a second end,
- wherein an interior volume of the insulating glass unit is defined between the first pane, the second pane, and the spacer,
- wherein the spacer defines a first corner, a second corner, a third corner, and a fourth corner positioned around a perimeter of the interior volume,
- wherein the spacer comprises a first spacer segment extending between the first end and the first corner, a second spacer segment extending between the first corner and the second corner, a third spacer segment extending between the second corner and the third corner, a fourth spacer segment extending between the third corner and the fourth corner, and a fifth spacer segment extending between the fourth corner and the second end, wherein the first spacer segment and the fifth spacer segment overlap between the first corner and the fourth corner and define an exterior seam outside of the interior volume at the second end of the spacer, and wherein the exterior seam is located between the first corner and the fourth corner.

A spacer frame for an insulating glass unit, the spacer frame comprising:
- a channel extending from a first end to a second end, wherein the channel defines a first corner, a second corner, a third corner, and a fourth corner of the spacer frame between the first end and the second end;
- wherein the channel further comprises:
- a first spacer segment extending between the first end and the first corner, wherein only a portion of the first spacer segment comprises an insert portion extending from the first end towards the first corner;
- a second spacer segment extending between the first corner and the second corner;
- a third spacer segment extending between the second corner and the third corner;
- a fourth spacer segment extending between the third corner and the fourth corner;
- and
- a fifth spacer segment extending between the fourth corner and the second end;
- wherein each of the first, second, third, fourth, and fifth spacer segments of the channel comprises a first side wall, a second side wall, and a bridge extending between the first and second side walls;
- wherein the fifth spacer segment overlaps the insert portion of the first spacer segment between the first corner and the fourth corner such that the second end of the channel forms an exterior seam on the first spacer segment;
- and wherein the exterior seam is located between the first corner and the fourth corner.

A spacer frame assembly comprising:
- a substantially linear channel having first and second ends, the substantially linear channel that when assembled. includes at least three sides and corresponding corners between each of said sides;
- a connecting structure located at one of said first and second ends and an opposite frame end located at the other of said. one of first and second ends, the opposite frame end having an inner channel for receiving a nose portion of said connecting structure;
- a stop extending from said connecting structure for locating the opposite frame end when in the assembled position;
- and
- a lateral connection spaced from said corresponding corners and along one of said at least three sides, the lateral connection forming a union point between said opposite frame end and said connecting structure.

A method of making a spacer frame assembly for bending into a multi-sided window or door spacer frame comprising:
- a) providing a supply of narrow metal strip coiled on a support;
- b) unwinding the metal strip from the support to provide an elongated metal strip and moving the elongated metal strip along a. path of travel to a stamping station;
- c) stamping the strip at spaced apart corner locations by removing portions of said strip at said corner locations wherein inter-fitting leading and trailing ends of the spacer frame assembly are defined by a lead portion of said strip extending in front a first corner location and a trailing portion of said strip extending behind a second corner location;
- d) additionally stamping at least one. of the lead and trailing portions of said strip to form an abutment stop comprising a wide portion of the strip and a nose which extends into said wide portion of said strip for defining an amount of overlap of the leading and trailing ends an assembled spacer frame;
- e) roll forming the strip to form a channel shaped structure having side walls that include the abutment stop and a base wall extending between the side walls;
- and
- f) severing the frame assembly from the elongated metal strip.
4 more elements
A spacer frame assembly for bending into a multi-sided window or door spacer frame comprising:
- an elongated metal strip bent to form a channel shaped frame element having a base wall that extends between two generally parallel side walls wherein the side walls include spaced apart corner locations defined by notches that extend from an edge of the metal strip into the side walls and wherein telescoping leading and trailing ends of the frame element are defined by a lead portion of said frame element in front and spaced from a first corner location, and a trailing portion of said frame element behind and spaced from a second corner location wherein at least one of the lead and trailing portions of said frame element include an abutment stop defined by a notch which extends into a side wall of said frame element, the abutment stop for limiting movement of the leading and trailing ends as said leading and trailing ends are telescoped one within the other and thereby define a lateral connection spaced from said corners and an. amount of overlap of the leading and trailing ends of the assembled spacer frame.
A spacer frame assembly comprising:
- a substantially linear channel having first and second ends, the substantially linear channel when assembled including at least three sides and corresponding corners between each of said sides;
- a connecting structure located at one of said first and second ends and an opposite frame end located at the other of said first and second ends, the opposite frame end having an inner channel for receiving a nose portion of said connecting structure;
- and
- a stop extending from said connecting structure for locating the opposite frame end when in the assembled position.
