DETAILED DESCRIPTION

As shown in the exemplary drawing figures, embodiments of a glass replacement panel and methods of retrofitting an appliance with a glass replacement panel are shown, wherein like elements are denoted by like numerals.
FIGS. 1A and 2 show an embodiment of a refrigerator 100 a. An example of such a refrigerator 100 a is the Series 7 24-inch refrigerator with a stainless steel door sold by Viking Range. The refrigerator 100 a has a housing 101 that has a top 102, a bottom 104, a rear wall 106, a left side wall 108, and a right side wall 110. The left side wall 108 is parallel with and faces the right side wall 110. The top 102 is attached to top edges of the left side wall 108 and the right side wall 110. Similarly, the bottom 104 is attached to bottom edges of the left side wall 108 and the right side wall 110, wherein the bottom 104 is parallel with and faces the top 102. As shown in FIG. 2 , the top 102, bottom 104, rear wall 106, and side walls 108, 110 define a cavity 112 in which one or more food items can be contained on shelving and drawers in a well-known manner. The cavity 112 is enclosed by a single door 114 a that is attached to the left side wall 108 via a pair of hinges (not shown). The door 114 a includes a handle 109 a. The refrigerator 100 a has a height of approximately 80 inches, a width of approximately 24 inches, and a depth of approximately 25 inches. Cooling of the cavity 112 is performed via a condenser (not shown) in a well-known manner and is not the subject of the present invention.
When originally sold, the door 114 of the refrigerator 100 a includes a plastic interior shelving unit 116 mounted to an interior facing portion of a rectangular, metal frame 118 of the door 114 a. As shown in FIG. 2 , the interior shelving unit 116 is a one-piece surface 119 that is attached to the frame 118 by an insulation process that involves inserting spray-foam between the interior shelving unit 116 and the metal frame 118. Besides providing insulation, the inserted spray-foam adheres the interior shelving unit 116 and the metal frame 118 to one another. The surface 119 defines multiple receiving areas for shelving structures 120 that are attached to surface 119 as shown in FIG. 2 . Of course, other shelving arrangements are possible.
The originally sold door 114 a has a standard stainless-steel door panel 122 or a custom wood door panel 124 attached to an exterior facing portion of the frame 118. Attachment to the frame 118 is accomplished in a number of ways, such as screw-type fasteners.
Note another possible embodiment for the originally sold refrigerator is refrigerator 100 b shown in FIG. 1B, wherein refrigerator 100 b has the same structure as refrigerator 100 a with the exception that its door 114 a is altered to have a custom wood door panel 124 with handle 109 b. While the prior discussion and the discussion to follow regarding FIGS. 1A and 2-22 regard the refrigerator 100 a, they equally apply to the refrigerator 100 b, since refrigerators 100 a and 100 b only differ from one another by the structures of the panels and handles used for their doors 114 a and 114 b.
As shown in FIGS. 3, 4A and 4B, there are a plurality of spot-welds 126 located along the longitudinal edges of the frame 118. There is an additional longitudinally extending array of spot-welds located between the holes at the longitudinal edges of the frame 118. In addition, there are spot-welds located in the top corners of the frame 118. The various spot-welds are used to attach the frame 118 to one or more metal structures (not shown) facing and abutting a face of the frame that faces the cavity 112 of the refrigerator 100 a.
For attachment between the frame 118 and either of the panel 122 or panel 124, a side channel 111 is attached to the left side of the frame 118 and a side channel 113 is attached to the right side of the frame 118. The side channels 111 and 113 are similar in structure to each other, wherein each is c-shaped. FIGS. 4A and 4B show an example of a side channel 111 that is attached to the face of the frame 118 facing away from the cavity 112. As shown, the middle surface 115 of the c-shape of the side channel 111 is attached to a side exterior side wall of the interior shelving unit 116 via screw-type fasteners. Such attachment results in an outer surface 117 of the c-shape to be furthest from the cavity 112 than a second outer surface 119 of the c-shape. The panel 122 or 124 is attached to the outer surface 117 via screw-type fasteners inserted through openings formed in the outer surface 117 as shown in FIG. 4B.
Note that hereinafter that elements denoted as “inner” or “outer” are so defined based on their relative distance from the door panel when attached. In particular, an inner element is positioned closer to the door panel than an outer element.
There are instances when a user is not satisfied with the external look of the original panel 122, 124 of the refrigerator 100 a. In this scenario, the user can retrofit the refrigerator 100 a so that the original panel 122, 124 is replaced by a glass panel system 128 that includes a mounting frame 130 to which a glass panel 131 is attached by performing the following processes:

- 1) removing the original panel 122, 124 by:
  - a. For each side channel 111 and 113, carefully remove a side trim covering the side channels 111 and 113;
  - b. Loosen fasteners at the top and bottom portions of the original panel 122, 124 and then remove all other fasteners of the original panel 122, 124;
  - c. While gripping the original panel 122 or 124, remove the loosened fasteners at the top and bottom portions of the original panel 122, 124 and then carefully lift the original panel 122, 124 off of the side channels 111 and 113;
- 2) when the original panel 122, 124 is removed, exposing the exterior facing portion 132 of the frame 118 so that the side channels 111 and 113 are exposed;
- 3) positioning the glass panel system 128 so that an attachment side 134 of the mounting frame 130 faces the exterior facing portion 132 of the frame 118 and the exterior facing portions of the side channels 111 and 113, wherein the glass panel 130 faces away from the exterior facing portion of 132 of the frame 118;
- 4) aligning attachment members, such as holes 136, of the attachment side 134 of the mounting frame 130 with holes formed in side channels 111 and 113;
- 5) engaging the aligned holes 136 and holes of the side channels 111 and 113 with screw-type fasteners, so that mounting frame 130 is attached to the frame 118 as shown in FIG. 4B. Other engagement schemes are possible. For example, the side channels 111 and 113 have multiple male engagement members that engage corresponding female members of the mounting frame 130 and vice versa.

As shown in the embodiment of FIGS. 5-10 , the glass panel system 128 includes the mounting frame 130 and the glass panel 131 attached thereto. The mounting frame 130 includes two identical side brackets 138 that are arranged parallel to one another and separated from one another by approximately 20 inches.
A more detailed view of a side bracket 138 is shown in FIGS. 9 and 10-12 . The side bracket 138 is an extruded piece of Aluminum that has multiple chambers formed as shown in FIG. 11 . The side bracket 138 has a length of approximately 79.35 inches, a width of approximately 2 inches, and a maximum thickness of 0.60 inches. The exposed openings 139 at the tops and bottoms of the side brackets 138 are sealed by inserting and attaching plastic caps 140 (see FIGS. 10A-10B) into the exposed openings. The caps 140 can be plastic injection molded and have snaps/tabs 141 that engage and lock to the side brackets 138. Moving the snaps/tabs away from the side brackets 138 releases the caps 140 from the side brackets 138.
The tops of the side brackets 138 are attached to one another by screws inserted into an inner top bracket 146 of a top bracket 142 that extends from the outer surface of the tops of the side brackets 138.
The inner top bracket 146 is made of metal, such as aluminum or cold rolled steel, and is painted or powder coated with a desired color. The outer top bracket 144 is made of galvanized steel, but is not painted. The top bracket 142, outer top bracket 144, and the inner top bracket 146 have a height of approximately 3.40 inches, a length of approximately 21.30 inches, and a thickness of approximately 0.55 inches.
As shown in FIGS. 10 and 13-15 , the outer top bracket 144 has bottom tabs 148 extending below the body 150 of the outer top bracket 144. Adjacent tabs 148 are spaced from each other by approximately 6 inches. As shown in FIG. 15 , there are holes 152 formed above each bottom tab 148, wherein such holes 152 are used for fastening of the outer top bracket to the inner top bracket 146 via screw-type fasteners inserted through corresponding holes of the inner top bracket 146 and engaging the holes 152. There is also a rivet bite 154 formed above each bottom tab 148 that hides a corresponding rivet head from the customer's view and is used for attachment of the outer top bracket 144 to the inner top bracket 146.
As shown in FIGS. 10 and 16-17 , the inner top bracket 146 has slots 156 and mounting holes 158 that are used for mounting with the outer top bracket 144. Prior to such mounting, one side of a foam piece 159 with a rectangular cross-section is adhered to an inner facing surface of the outer top bracket 144, as shown in FIG. 18 . The foam piece 159 prevents rattling of the outer and inner top brackets 144, 146 due to part vibration. Next, an outer facing surface of the inner top bracket 146 is aligned with the inner facing surface of the outer top bracket 144 such that the bottom tabs 148 are aligned with corresponding ones of the slots 156 of the inner top bracket 146. The tabs 148 are inserted into the corresponding slots 156 to which they are aligned. With such insertion, the outer facing surface of the inner top bracket 146 contacts an adhesive surface of the foam piece 159 so that adhesive attachment between the foam piece 159 and the outer top bracket 144 and the inner top bracket 146 is achieved. Further attachment is achieved by having painted pop rivets inserted into through-holes 154 and riveted to inner top bracket 146. Note that the tabs 148 allow the pop rivets to be hidden by the sheet metal thickness of the larger through-holes 154. Thus, a single top bracket 142 is formed. As shown in FIG. 19 , an inner facing face 160 of the top bracket 142 and inner top bracket 146 has a rectangular adhesive tape 162, such as the double-sided adhesive tape sold by 3M under the trademark VHB.
The inner top bracket 146 has end flanges that face and contact the walls of the side brackets 138 that face one another. The end flanges have openings that are aligned with corresponding openings of the walls of the side brackets 138 that face one another. The inner top bracket 146 is attached to the side brackets 138 by inserting screw-type fasteners into the aligned openings of the inner top bracket 146 and the side brackets 138. With attachment, a top flanges of the inner top bracket 146 fit over and engage the exposed tops of the side brackets 138. When the above-described inner top bracket 146 of top bracket 142 is attached to the side brackets 138 via screw-type fasteners, the side edges of the inner and outer top brackets 144 and 146, and, thus, the side edges of the top bracket 142 while overlapping the side brackets 138 either align with the outer side edges of the side brackets 138 or are offset inward from the outer side edges of the side bracket by approximately 1 inch. In addition, the top edges of the inner and outer top brackets 144 and 146 and top bracket 142 align with the top edges of the side brackets 138. The end result is that the inner facing face of the inner top bracket 146 and the inner facing faces of the side brackets 138 form a common plane for accepting an adhesive tape 162, the function of which is described hereinafter.
As shown in FIG. 10 , the bottoms of the side brackets 138 are attached to one another by screws inserted into an inner bottom bracket 168 of a bottom bracket 164 that extends from the outer surface of the bottoms of the side brackets 138. Attachment between the side brackets 138 and the bottom bracket 164 is achieved by using screw-type fasteners much in the same manner that the top bracket 142 is attached to the side brackets 138. Other than their height of approximately 9.5 inches and the use of two pieces of foam 159 to eliminate rattles between the outer bottom bracket 166 and the inner bottom bracket 168 and placed within the bottom bracket 164, the outer bottom bracket 166, inner bottom bracket 168, and bottom bracket 164 are similar in structure and construction as the outer top bracket 144, the inner top bracket 146, and top bracket 142, respectively, as previously described.
Note that it is preferred that the caps 140 are inserted prior to the pop rivets being used to attach the outer bottom bracket 166 to the inner bottom bracket 168 and the outer top bracket 144 to the inner top bracket 146. Once inserted in the exposed openings of the side brackets 138, the caps 140 hide holes in the side brackets 138 and prevent people from accidently grazing the edges of the exposed openings 139. An example of attachment of a cap 140 to the exposed opening of a side bracket 138 that is attached to either the top bracket 142 or the bottom bracket 164 is shown in FIG. 21 .
When the above-described bottom bracket 164 is attached to the side brackets 138 via screw-type fasteners, the side edges of the outer and inner bottom brackets 166 and 168, and thus the bottom bracket 164 align with the outer side edges of the side brackets 138. In addition, the bottom edges of the outer and inner bottom brackets 166 and 168 and bottom bracket 164 align with the bottom edges of the side brackets 138. The end result is that the inner facing face of the inner bottom bracket 146 and the inner facing faces of the side brackets 138 form a common plane for accepting an adhesive tape 162, the function of which is described hereinafter.
As shown in FIGS. 10 and 20 , the mounting frame 130 includes a rectangular, central bracket 170 that is made of a metal, such as galvanized steel. The central bracket 170 has a length of approximately 56.3 inches, a width of approximately 20.3 inches, and a thickness of approximately 0.39 inches. The top edge of the central bracket 170 is separated from the bottom edge of the top bracket 142 by approximately 5 inches. The bottom edge of the central bracket 170 is separated from the top edge of the bottom bracket 164 by approximately 5.3 inches. The left side edge of the central bracket 170 has holes that are aligned with holes formed in a left side bracket 138, wherein screw-type fasteners (not shown) are inserted into the aligned holes and attached the central bracket 170 to the left side bracket 138. Attachment between the central bracket 170 with the right side bracket 138 is accomplished in a similar manner.
As shown in FIGS. 10 and 20 , two rectangular pieces of closed-cell insulation foam 172 are attached to the central bracket 170 via an adhesive backing. The end result is that the surfaces 173, 175, 177, 179 of the side brackets 138, the top bracket 142, and the bottom bracket 164 that face the glass panel 131 are contained in a common plane that is preferably perpendicular to the floor surface on which the refrigerator 100 a is supported. Upon each of such surfaces, one or more double-sided adhesive tape 162 sold by 3M under the trademark VHB are attached along the longitudinal extent of the brackets 138, 142, and 164.
The single rectangular glass panel 131 has a width of approximately 24 inches, a length of approximately 80 inches, and a thickness of approximately 4 mm is attached to the mounting frame 130. The glass panel 131 is preferably mirror-finish black glass.
Horizontal strips of two-sided adhesive tape 162 are applied to the inner facing surfaces of the inner top bracket 146 and the inner bottom bracket 168 and the surfaces 173 and 175 of the left and right side brackets 138. Prior to application of the tape 162, the surfaces to which they are applied should be cleaned with an 50% to 70% isopropyl alcohol solution. With the adhesive tape 162 in place on the top bracket 142, bottom bracket 164, and side brackets 138, a side of the glass panel 131 facing the mounting frame 130 is applied to the adhesive tape 162 on the side brackets 138 and pressure is applied. Next, pressure is applied at the top and bottom of the glass panel 131 so that the adhesives of the top bracket 142 and the bottom bracket 164 engage the surface of the glass panel 131 facing the mounting frame 130. Pressure is applied to the glass panel 131 and the mounting frame 130 by a fixture or a jig that control the amount of pressure applied and the amount of time of such application. A pressure of approximately 250 kPa (36 psi) is applied for approximately 1 minute by the fixture or jig. The product will then “dwell” for approximately 48 to 72 hours before the glass panel system 128 is ready to be transported and used for retrofitting the refrigerator 100 a. The adhesive tape 162 is applied when the temperature ranges from 50° F. to 100° F., preferably 70° F. to 100° F. Note that while other attachment mechanism can be used to attached the glass panel 131 to the mounting frame 130, it is preferred that attachment is achieved solely using the adhesive tape 162 described previously.
A U-shaped handle 176 is attached to the outer surface 176 of the glass panel 131 via screw fasteners. An embodiment of the handle 176 is shown in FIGS. 8A-D. Depending on the style of the refrigerator 100 a, the handle 176 can be mounted on the right side or the left side of the glass panel 131. The handle 176 can be an aluminum extrusion that is black-chrome plated and has two endcaps 178 with plastic bumpers 180 on the side of the glass panel 131 that faces the mounting frame 130. The handle 176 includes a longitudinal extrusion 182 with a hollow profile that accepts a male portion 184 of each endcap 178. As shown in FIG. 8D, each endcap 178 has hollow profiles 186 that receive male projections 188 of the plastic bumpers 180. In particular, the central bracket 170 has embosses that provide contact surfaces/supports for handle mounting screws. The handle endcaps 178 are “capped” with the plastic spacer or bumper 180 to prevent metal/glass interactions as much as possible. To ensure a strong grip on handle endcaps, blue-grade Loctite is applied on the screws used for attachment of the handle 176 to the glass panel 131 and the central bracket. As shown in FIG. 20 (wherein glass panel 131 is transparent and not tinted for illustrative purposes only), the central bracket 170 provides support for screws to attach the handle 176 to the glass panel 131 and the central bracket 170.
Note that the central bracket 170 could be replaced by ribs or multiple spaced rectangular brackets that are smaller than the central bracket 170.
