A multiple pane glass assembly having at least one pane that is electrically heatable. The glass panes of the assembly are disposed in closely spaced, side-by-side relation with a spacer interposed between adjacent panes. The spacers include a plurality of hollow tubular members disposed near the peripheral edges of the panes with adjacent ends of the tubular members connected by corner key elements. Electrical lead wires extending from an interior electrically heatable surface of one of the panes are directed through respective apertures or passageways in the corner key elements, into the end of a respective tubular member connected to the corner key element, and through the tubular spacer members to a common egress location. The corner key elements are adapted to retain desiccant material in at least some of the tubular members, which together with sealant applied about the periphery of the assembly, enables an air-tight sustantially vapor-free condition to be maintained in the space between panes. Because the electrical lead wires are trained through the tubular spacer members, sealant may be applied about the outer periphery of the assembly and the assembly efficently handled without the impediment of exposed lead wires. The apertured corner key elements further permit easy filling of the interior of the assembly with an inert gas to improve its insulating efficiency.

Glass assembly for refrigerator doors and method of manufacture

A door-operating mechanism is disclosed which is particularly suited for use with hingedly mounted swinging glass doors of a refrigerated display cabinet. The door operating mechanism includes an extensible gas spring biased toward an extended condition, and a linkage arrangement operatively interconnecting the gas spring with the door. A portion of the gas spring is movably disposed within a slot defined by the linkage arrangement such that in one position of the gas spring the door is biased toward its closed position, and in another position of the gas spring the door may be maintained in an opened position such as for stocking or maintenance of the display cabinet.

Door operating mechanism

An improved adjustable mounting arrangement for mounting a glass door assembly on a door frame for a refrigerated display cabinet. The mounting arrangement includes upper and lower hinge assemblies for providing swinging movement of the door assembly relative to the door frame, with the hinge assembly accommodating adjustment of the hinge axis relative to the door frame for alignment of the door assembly in order to provide effective sealing and enhanced appearance of the display case. The hinge assemblies include upper and lower hinge brackets which are adapted to receive upper and lower hinge pins of the door assembly, the brackets being adapted to be attached to frame members of the door frame in different positions for effecting alignment of the door.
