Reach-in door for refrigerated merchandiser
First Claim
1. A transparent door that, in use, is movably mounted to provide reach-in access to the lighted interior product area of a refrigerated merchandiser, the door comprising:
- an unsealed glass subassembly having first and second spaced apart glass lites with inward and outward facing surfaces, a unitary spacer extending around and in contact with an outer periphery of the glass lites and having a separator section disposed between said glass lites and flanges integrally formed as one piece with the separator section to engage outer peripheral edges of said glass lites, and key locking means cooperatively engaged with said spacer for lockingly maintaining it in peripheral contact around the glass lites; and
a molded frame surrounding the outer periphery of the glass subassembly and sealably encasing said spacer and adjacent marginal edges of said glass lites around the flanges.

Abstract
A refrigerated, reach-in merchandiser having a product display area with a front opening defined by casing means having at least two mullion members, a reach-in door for closing the front opening and being hingedly mounted on one of the mullion members by door control means, said reach-in door having a transparent panel with a molded frame and at least two glass lites, a door control for hingedly mounting the door on said merchandiser, an electric member for said merchandiser including a light on one of the mullion members for illuminating the display area, said electric member also including a heating element for the glass lites of the transparent panel and including a key member for connecting said heating element to said merchandiser.

38. A transparent door that, in use, is movably mounted to provide reach-in access to the lighted interior product area of a refrigerated merchandiser, the door comprising:
-
a transparent panel with a glass subassembly having at least two glass lites, an integral one-piece spacer member formed to span across and engage the marginal edges of said glass lites and to maintain a spaced relation therebetween, and a key locking member for maintaining said spacer member assembled in peripheral contact around the glass lites; a molded frame sealably surrounding the outer periphery of the glass subassembly; door control means for hingedly mounting said door; and electrical means including heating means for heating at least one of the glass lites of the transparent panel and means for connecting said heating means through said key locking member. - View Dependent Claims (39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 61, 62)

63. A transparent door that, in use, is movably mounted to provide reach-in access to the lighted interior product area of a refrigerated merchandiser, the door comprising:
-
a glass subassembly having first and second spaced apart glass lites with inward and outward facing surfaces, an integral one-piece strip spacer formed to extend peripherally around and engages the glass lites and having an inner separator body portion with an outer wall forming side sealing flanges on each side of the body portion, said first and second glass lites being assembled on the strip spacer with the separator body portion engaging the opposed inner surfaces of the glass lites and the side sealing flanges overlying the peripheral edges margins of the lites; a molded frame surrounding the outer periphery of the glass subassembly and sealably encasing said strip spacer, said strip spacer being constructed and arranged for blocking frame molding material from entering between the first and second glass lites during molding assembly. - View Dependent Claims (64, 65, 66, 67, 68, 69)

70. A transparent door that, in use, is movably mounted to provide reach-in access to the lighted interior product area of a refrigerated merchandiser, the door comprising:
-
an unsealed glass subassembly having first and second glass lites assembled in spaced relation on a peripheral one-piece strip spacer said spacer extending around and engaging an outer peripheral edges of each of said glass lites; a molded frame sealably encasing the glass subassembly and having a vertical inner hinge margin and transverse upper and lower ends; a first hinge pin at one of the upper and lower ends of the frame for its pivotal connection to the refrigerated merchandiser, the first hinge pin being constructed and arranged for turning connection in the frame whereby the frame pivots with respect to the first hinge pin; and
means for seating the end of the first hinge pin for non-turning movement on the refrigerated merchandiser;an elongate torsion rod having a first end fixedly connected to the first hinge pin and another end fixedly connected to the frame such that, in use, swinging movement of the door in an opening direction relative to the merchandiser will twist the torsion rod about its longitudinal axis whereby the torsion rod applies a spring force opposing the opening direction for biasing the door toward a closed position; a first gear mounted on said other end of the torsion rod for conjoint movement therewith about the longitudinal axis of the torsion rod; and a second gear mounted within the door frame and engageable with the first gear for selectively rotating the first gear to preadjust the torsional spring force of the rod. - View Dependent Claims (71, 72)

73. A transparent door that, in use, is movably mounted to provide reach-in access to the lighted interior product area of a refrigerated merchandiser, the door comprising:
-
a glass panel having first and second generally rectangular spaced apart lites having peripheral edges, the first lite having an inner surface formed with electrically conductive film thereon; an integral one-piece spacer of electrically insulating material disposed generally between the lites and engaging the peripheral edges of the lites; a molded frame surrounding the peripheral edges of the first and second lites and encasing the one-piece spacer, the door being constructed with heating means for heating the electrically conductive film to clear condensation on the glass panel during use of the door on the merchandiser; said heating means including a first flat, elongate bus bar disposed between the spacer and the first lite along one of the peripheral edges of the first lite, the first bus bar engaging the inner surface of the first lite to permit electrical conduction between the first bus bar and the electrically conductive film thereon; a second flat, elongate bus bar disposed between the spacer and the first lite along an opposed peripheral edge of the first lite opposite to the first bus bar, the second bus bar engaging the inner surface of the first lite to permit electrical conduction between the second bus bar and the electrically conductive film on the inner surface; the first and second bus bars being constructed and arranged for connection to an electrical power source external of the door thereby to permit an electrical current to flow in the electrically conductive material on the inner surface of the first lite for generating heat on said inner surface. - View Dependent Claims (74, 75, 76, 77, 78, 79)
