Abstract
Description
- Benefit is claimed of U.S. Patent Application Ser. No. 60/744,048, filed Mar. 31, 2006, and entitled “Refrigerated Case”, the disclosure of which is incorporated by reference herein as if set forth at length.
- The invention relates to refrigerated cases. More particularly, the invention relates to lighted signs for such cases.
- In several configurations of refrigerated case (including freezers), a backlit sign is positioned along a header above the case doors. The sign includes an at least partially transparent or translucent panel held in front of one or more lightbulbs. Such panels must often be removed (e.g., to replace the panels or replace the bulbs). Various panel retention mechanisms are known. In one group, the panel is held within a metallic frame. A lip of the frame engages a perimeter portion of the panel front surface/face. A lower edge of the panel may be supported by a bottom portion of the frame. To retain the panel against rearward movement, a plurality of screws extend through the frame. Tip portions of the screws in the interior of the frame engage a perimeter portion of the panel rear surface/face.
- To remove the panel for panel or bulb replacement, some or all of the screws are at least partially unscrewed to retract their tip portions and permit disengagement of the tip portions from the panel rear face. The panel may then be rotated and/or translated in a series of movements to permit its removal (optionally including a slight bending/flexing of the panel). Panel replacement/reinstallation may be by a reverse of this process.
- Such use of screws may have one or more of several disadvantages. Unscrewing and rescrewing may be cumbersome and time-consuming. The potential exists for stripping of the screwhead and/or the frame hole.
- Accordingly, one aspect of the invention involves a refrigerated display case having a body, at least one door coupled to the body, and an internal refrigerated compartment. The case includes a lighted sign apparatus mounted to the body. The apparatus includes a bulb, a housing, and an at least partially transparent and/or translucent sign carried by the housing. A number of extractable snap fasteners extend through associated holes in the housing and engage the sign to retain the sign in an installed condition.
- In various implementations, the snap fasteners may include a first group along the bottom of the housing and a second group along a top of the housing. The snap fasteners may consist essentially of nylon. The snap fasteners may comprise a head and a transversely-apertured shaft depending from the head. The housing may comprise first and second pieces. The first piece may essentially form a top and first side of the housing and the second piece may essentially form a bottom and second side of the housing. The sign may be replaceable by extracting at least one of the fasteners, removing the sign, replacing the sign with a replacement sign, and replacing the extracted fastener(s). A similar process may be used for bulb replacement.
- The details of one or more embodiments of the invention are set forth in the accompanying drawings and the description below. Other features, objects, and advantages of the invention will be apparent from the description and drawings, and from the claims.

FIG. 1 shows a refrigeratedcase 20 having ahousing 22 surrounding aninterior compartment 24. In theexemplary case 22, a recirculating airflow is directed from/to thecompartment 24 by a refrigeration equipment cassette 26 (e.g., containing the compressor, heat exchangers, expansion device, fans, and the like). Theexemplary case 20 has a pair ofdoors lighted sign 32. - Each exemplary door includes a
frame 40 holding one or more glass or othertransparent panes 42. Each exemplary door is supported by a pair of upper andlower hinges opposite handle 48. The door may be held in a closed condition by means of a magnetic seal, biasing spring, or gravity cam device (not shown). Anexemplary sign 32 extends essentially full case width and spans the doors. Theexemplary sign 32 includes a frame orhousing 60 holding asign panel 62 in front of alightbulb 64. Via an appropriate combination of opaque, transparent, and translucent areas of different color, opacity, texture, and the like, thepanel 62 provides a lighted graphitic having design and/or written elements. - The
exemplary bulb 64 is an elongate transversely-extending florescent bulb.FIG. 2 shows thebulb 64 on afixture 66 mounted to afront surface 68 of aheader area 70 of amain housing body 72.FIG. 2 further shows thepanel 62 as having front andrear faces lower edges interior space 88. - The exemplary housing forms an
upper wall 90 and alower wall 92. Alip 94 extends downward (depends) from a forward edge of theupper wall 90. Asimilar lip 96 extends upward from a forward edge of the lower wall. A rear end portion of theupper wall 90 overlaps a forward portion of anupper surface 100 of themain housing body 72. To mount thehousing 60 to themain housing body 72, screws (e.g., sheetmetal screws) 102 may extend through holes in the overlapping portions. Exemplary screws are self-threading, passing with clearance through apertures in theupper wall 90 and threaded into the apertures in themain housing body 72. Similarly, arear lip 110 may depend from a rear edge of thelower wall 92. Thelip 110 may similarly be secured to themain housing body 72 along thefront surface 68. - The rear faces of the
lips front face 80 of thepanel 62. Perimeter portions of therear face 82 may be retained by upper and lower arrays ofsnap fasteners 120 extending through the upper and lower walls, respectively. Exemplary snap fasteners are “arrow clips” available from Micro Plastics, Inc, Flippin, Ark. Gaps may be provided in one or both of the overlapping portion of the top wall or therear lip 110 to accommodate, for example, adjacent hinges, latches, and the like. -
FIGS. 4 and 5 show thehousing 60 as including respective left andright sidewalls 122 and 124 (left being viewed from the point of view of the case rather than a person facing the case). -
FIGS. 7-10 show an exemplary housing formed of two metal pieces, a first piece 130 (FIGS. 7 and 8 ) forms theupper wall 90 andlip 94 as well as theleft sidewall 122 and associated front lip. Similarly, the second piece 140 (FIGS. 9 and 10 ) forms thelower wall 92 and its associated lips as well as theright sidewall 124 and an associated front lip. The two pieces may be secured to each other (e.g., by screwing, riveting, tack welding, or the like). Theupper wall 94 andlower wall 92 include pluralities of holes/apertures 150 for receiving thefasteners 120. -
FIGS. 11 and 12 show the snap fasteners having ahead 200 and ashaft 202 depending from the head and extending to atip 204. The exemplary shaft has a transversecentral aperture 206 which may provide a resilient bias for shaft branches along either side of the aperture. The exemplary branchouter surfaces 210 have a first relaxed separation at a central location, tapering both distally and proximally therefrom to provide for snap fit insertion and removable extraction through acomplementary hole 150 in the housing. The exemplarycomplementary hole 150 is elongate to correspond to the elongate cross-section of the fastener. The exemplary fasteners are non-barbed to provide non-destructive removability (e.g., by placing a fork-like tool between the head and the housing and prying). The non-destructability allows for re-insertion. Alternative embodiments may involve fasteners which are destroyed or damaged and may be replaced with replacement fasteners. Exemplary fasteners are of a polymeric or plastic material such as nylon. For easy tool access, the holes may be oriented longitudinally (i.e., with their longer dimension front-to-back). - One or more embodiments of the present invention have been described. Nevertheless, it will be understood that various modifications may be made without departing from the spirit and scope of the invention. For example, the principles may be applied in the retrofit of an existing case or the reengineering of an existing case configuration. In an exemplary retrofit or reengineering situation, existing screw holes may be enlarged to form the snap fastener holes or may be replaced or supplemented. Accordingly, other embodiments are within the scope of the following claims.
