RELATED APPLICATIONS

[0001] This application claims priority to co-pending U.S. Provisional Application No. 60/763,601, filed Jan. 31, 2006, the entire contents of which is hereby incorporated by reference.

BACKGROUND

[0002] The present invention relates to a glass-front display merchandiser. More particularly, the invention relates to a glass-front display merchandiser with wedge-style cases.

[0003] Glass-front display merchandisers, sometimes referred to as deli or service merchandisers are generally assembled from aligned modular sections or cases. The modular cases typically include straight cases of variable lengths (e.g., 4, 6, 8, 10, or 12 feet long) and inside and outside wedge cases of variable arc length (e.g., 45 and 90 degrees). The different modular cases can be aligned end to end and assembled to form a linear merchandiser or a merchandiser having a customized shape, such as a 90 degree corner, a bump out, an inlet, or an S-curve.

[0004] Typically, display merchandisers that include only straight cases have glass fronts made from "straight glass" panes. Straight glass is used to described a generally planar glass pane. When straight cases are assembled together end-to-end, the adjacent ends of the straight glass panes are aligned with each other to provide the illusion of a single seamless elongated merchandiser. Alternatively, when a customized shape is desired, the glass fronts of the straight cases can use "curved glass" and the glass fronts of the wedge cases can use "spherical glass" panes. Curved glass refers to glass panes that are curved when viewed in a vertical cross-section, and that are flat when viewed in a horizontal cross-section. Spherical glass is curved in both the horizontal and vertical cross-sections. When a straight case is assembled together with a wedge case the adjacent ends of the spherical and curved glass panes are aligned with each other along a curved path to similarly provide the illusion of a single seamless customized merchandiser.

[0005] FIG. 1 illustrates a prior art straight case 10 with a curved glass pane 12. The case 10 generally includes a product display area 14 that supports food product (not shown) available to consumers in a retail setting. The case 10 further includes a base 16 and an upper case frame or case top 18. The base 16 includes a front portion 20 and a rear portion 22 which partially define the product display area 14. At least one strut 24 connects the case top 18 and the rear portion 22 of the case 10. A lower portion 26 of the curved glass pane 12 contacts the front portion 20 to maintain the food product in the product display area 14 at predetermined conditions.

[0006] With further reference to FIG. 2, an upper portion 28 of the curved glass pane 12 is pivotally attached to the case top 18 above the product display area using a clamp 30 and a hinge 32. When curved glass panes are attached, the clamp 30 is linear. Alternatively, when spherical glass panes are attached the clamp 30 is bent to match the curve of the upper edge of the spherical glass pane. An extruded stationary front profile 35 is attached to the case top 18 and provides a transition between the clamp 30 and the case top 18. The clamp 30 includes a clamping axis 34 that defines an angle A (e.g., a clamping angle) relative to a vertical axis 36. This angle A is typically approximately 55 degrees. The hinge 32, case top 18, and front profile 35 are collectively referred to as spherical glass hardware because they are used to mount curved and spherical glass panes.

[0044] FIGS. 3-6 illustrate an inside wedge-style display case 100 of a display merchandiser (not shown) according to one embodiment of the invention. The case 100 includes a product display area 102 that supports food product (not shown) available to consumers in a retail setting. The case 100 further includes a base 104, a glass pane 106, and an upper case frame or case top 108 he base 104 includes a front portion 110 and a rear portion 112 which partially define the product display area 102. In some embodiments, the case 100 is a refrigerated display case, and the base 104 encloses at least a portion of a refrigeration system which refrigerates the food product. In other embodiments, the case 100 can be a dry case or a hot case, and the base 104 can enclose at least a portion of an air circulation system or heating system, respectively. Two struts 114 are located at opposite ends of the case 100 and connect the case top 108 and the rear portion 112 of the case 100. As shown in FIG. 5, the case 100 extends through an angle of approximately 45 degrees, although other embodiments of the case 100 can extend through any angle less than or greater than 45 degrees.

[0045] The glass pane 106 is conically-shaped as if cut from a cone pointing in the downward direction. A lower portion 116 of the glass pane 106 contacts the front portion 110 to maintain the food product in the product display area 102 at predetermined conditions. With further reference to FIG. 7, an upper portion 118 of the glass pane 106 is pivotally attached to the case top 108 above the product display area 102 using a clamp 120 and a hinge 122. An extruded stationary front profile 125 is attached to the case top 108 and provides a transition between the clamp 120 and the case top 108. The hinge 122, the case top 108, and the front profile 125 are collectively referred to as spherical glass hardware because they are used to secure curved and spherical glass panes to the case 100. The conically-shaped glass 106 is best shown in FIGS. 13-15. With reference to FIG. 15, the conically-shaped glass 106 is straight when viewed in a vertical cross-section. Alternatively, the conically-shaped glass is curved when viewed in a horizontal cross-section such as the top edge 118 shown in FIG. 13.

[0046] As best shown in FIGS. 9-11 and 16-18, the clamp 120 is bent to match the curve of the upper edge 118 of the glass pane 106. Alternatively, to hold straight glass in a straight case, the clamp 120 is linear. The clamp 120 includes a base 126, a top portion 128, and a back wall 130 connecting the top portion 128 and the base 126. The base 126, the top portion 128, and the back wall 130 define a slot configured to receive the top edge 118 of the glass pane 106. The base 126 includes a channel 132 that operates to secure a nut 134. The base 126 is connected to the hinge 122 by inserting a fastener through the hinge 122 and into the nut 134 (FIG. 7) secured by the channel 132. Fasteners are generally located at the ends of the clamp 120. The back wall 130 further includes a plurality of equally-spaced apertures 136 that receive corresponding set screws.

[0047] The top portion 128 includes a forward extension 138 and a rearward extension 124 extending from the back wall 130. A bottom surface 140 of the forward extension 138 includes ridges for gripping the upper surface of the top edge 118 of the glass pane 106. A wedge 142 extends the length of the glass pane 106. The wedge 142 also includes a top surface 144 having ridges for gripping the bottom surface of the top edge 118 of the glass pane 106. The wedge 142 further includes a bottom surface 146 that is in sliding contact with an upper angled surface 148 of the base 126. Tightening the set screws forces the wedge 142 away from the back wall 130 and down the upper surface 148 of the base 126. In turn, this moves the wedge 142 closer to the forward extension 138 to clamp the glass pane 106 between the ridged surfaces of the wedge 142 and the forward extension 138. In some embodiments, the top edge 118 of the glass pane 106 is covered with a hard silicone trim piece 150 to assist in clamping the glass pane 106.

[0048] As shown in FIG. 18, a clamping axis 152 is defined parallel to the bottom surface 140 of the forward extension 138 and the upper surface 144 of the wedge 142. In some embodiments, the clamping axis 152 may be defined along the straight profile of the conically-shaped glass 106 when viewed in the vertical cross-section. The clamping axis 152 defines an included angle B (e.g., a clamping angle) relative to a vertical axis 154. This angle B is typically approximately 34 degrees. In other embodiments, the angle B can be between the range of 30-35 degrees. In vet other embodiments, the range can be 30-40 degrees, and even other embodiments, the range can be 25-45 degrees.

[0049] FIGS. 19-22 illustrate an outside wedge-style case 200 of a display merchandiser (not shown) according to another embodiment of the invention. For this embodiment illustrated in FIGS. 19-30, two-hundred-series reference numbers are used and reflect similar structure represented by the corresponding one-hundred-series reference numbers used for the previous embodiment illustrated in FIGS. 3-18. The case 200 includes a product display area 202 that supports food product (not shown) available to consumers in a retail setting. The case 202 further includes a base 204, a glass pane 206, and an upper case frame or case top 208. The base 204 includes a front portion 210 and a rear portion 212 which partially define the product display area 202. In some embodiments, the case 200 is a refrigerated display case, and the base 204 encloses at least a portion of a refrigeration system which refrigerates the food product. In other embodiments, the case 200 is a dry case or a hot case, and the base at least partially encloses an air circulation system or a heating system, respectively. Two struts 214 are located at opposite ends of the case 200 and connect the case top 208 and the rear portion 212 of the case 200. As shown in FIG. 22, the case 200 extends through an angle of approximately 45 degrees, although other embodiments of the case 200 can extend through any angle less than or greater than 45 degrees.

[0050] The glass pane 206 is conically-shaped as if cut from a cone pointing in the upward direction A lower portion 216 of the glass pane 206 contacts the front portion 210 to maintain the food product in the product display area at predetermined conditions. An upper portion 218 of the glass pane 206 is pivotally attached to the case top 208 above the product display area 202 using a clamp 220 and hinge 222. An extruded stationary front profile 225 is attached to the case top 208 and provides a transition between the clamp 220 and the case top 208. Similar to the previous embodiment, the hinge 222, case top 208, and the front profile 225 are collectively referred to as spherical glass hardware because they are used to mount curved and spherical glass panes to the case 200. The conically-shaped glass 206 is best shown in FIGS. 27-30. With reference to FIG. 30, the conically-shaped glass 206 is straight when viewed in a vertical cross-section. Alternatively, the conically-shaped glass 206 is curved when viewed in a horizontal cross-section such as the top edge 218 as shown in FIG. 28.

[0051] As best shown in FIGS. 23-26, the clamp 220 is bent to match the curve of the upper edge 218 As shown in FIG. 31, the clamp 220 has the same cross-section as the clamp 120 and is similar to the clamp 120 in all respects except that it is bent in the opposite direction. Similar to the clamp 120, tightening the set screws forces the wedge 242 away from the back wall 230 down the upper surface 248 of the base 204. In turn, this moves the wedge 242 closer to the forward extension 238 to clamp the glass pane 206 between the ridged surfaces of the of the wedge 242 and the forward extension 238.

[0052] To assemble a display merchandiser, multiple straight or wedge-style cases 100, 200 can be aligned end-to-end to result in a merchandiser of a customized shaped. When two wedge-style cases 100, 200 are positioned together, the adjacent edges of the conically-shaped glass 100, 206 are aligned along a linear path. Similarly, when a wedge-style case 100, 200 is positioned next to a straight case, the adjacent edge of the conically-shaped glass pane 106, 206 of the wedge-style case is aligned along a linear path with the adjacent edge of a straight glass pane of the straight cases. The alignment of the edges of the glass panes creates a smooth transition between cases giving the illusion of a single, seamless display merchandiser.

[0053] To convert a display merchandiser that includes curved glass panes on the straight cases and spherical glass panes on the wedge-style cases to a display merchandiser that includes straight glass panes on the straight cases and conically-shaped glass panes on the wedge-style cases the curved and spherical glass panes and the clamps are removed. Next, the clamps 120, 220 are connected directly to the hinges 122, 222 of the spherical glass hardware. Then, the conically-shaped glass panes 106, 206 are mounted to the wedge-style cases 100, 200 using the clamps 120, 220 and straight glass is mounted on the straight cases using the same type of clamps 100, 220.

[0054] Thus, the invention provides, among other things, a display merchandiser that includes a case having conically-shaped glass panes, glass clamps that can be used to support conically-shaped glass and straight glass onto spherical glass hardware, and a method for converting a display merchandiser from having curved and spherical glass to straight and conically-shaped glass.
