I 12 Claims. 1

This invention relates to a combination reflector and showcase frame member, and particularly to means for mounting fluorescent or other elongated light tubes for lighting the interior of a showcase.

The present invention comprises a new showcase structure in which the reflector is secured to the end walls of the showcase and made a more or less permanent part thereof, to provide a substantial support for the glass plate forming the top wall of the showcase, and the cornice structure or rail is detachably secured to the reflector. The present arrangement makes it unnecessary to disturb the reflector if the top glass plate and/or the front glass plate are to be replaced. In one form of the invention, the cornice structure is detachably secured to the reflector in such a manner as to make it unnecessary to disturb the top glass plate if the front glass plate is to be replaced.

The cornice structure of the showcase of the present invention provides a safe conduit for concealed electrical wiring that is readily accessible for inspection and repair of the wiring without disturbing the reflector. Additionally, .the reflector cooperates with the cornice to hold the top edge of the vertically disposed glass wall securely in position.

The structure by which the various results and advantages of the present invention are attained will be described in connection with the accom panying drawings, in which:

Figure 1 is a front perspective View of a showcase embodying the invention;

Fig. 2 is a top view, partly in elevation and partly in section, showing the cornice removed from the showcase and showing the mortise plate structure by which the reflector is secured to the end walls of the showcase;

.Fig. 3 ,is'a cross sectional view, taken along the line 3--3 of Fig. 2;

Fig. 4 is a cross sectional view, taken along the line 4 4 of Fig. 1; and

Fig. 5 is a view, similar to Fig. 4, showing a modified embodiment of the invention.

In the drawings, the reference numeral 2 indicates a showcase having a front wall 3, a top wall4, and a pair of end Walls 5. End walls 5 may be metal, wood or any other suitable material, wood being the usual material, and are each provided adjacent its frontedge with a vertically disposed channel or groovefi in which the edges of the glass plate forming front wall 3 are slid andretained. ..The front edge of each end wall 5 may be notched or recessed slightly,

as indicated at i, for a purpose hereinafter described. A mortise plate 8 is secured to the inside of each end wall 5 by means of screws 9. Plates 8 fit in shallow recesses it] so as to be flush with the inner surfaces of end walls 5. If end walls 5 are made of thin metal, instead of wood, plates 8 may be welded or riveted thereto. Plates 8 are each provided with a plurality of threaded apertures 11 l The reflector l2, of any suitable material but preferably of a metal which can be extruded or drawn, has an end plate It welded or brazed to each end. Plates l3 are apertured to register with apertures H in mortise plates 8 and are secured thereto by metal screws [4, thereby making the reflector an integral partof the showcase structure at the corner where projections from the top glass plate and front glass plate intersect.

The inside surface of the reflector may be finished in any desirable manner to provide maximum light reflection. In addition to providing adequate light reflection the reflector is utilized to cooperate with the cornice to support the top edge of glass plate 3, and is therefore shaped with due consideration for the dual purpose it performs.

Both outer edges 15 and [5 of the reflector are curved or otherwise shaped to fit around opposite sides of an elongated light tube I-i at a proper distance to reflect the light rays downwardly into the showcase. Preferably the light tube is of small diameter, such as the fluorescent tube sold under the trade-mark Slimline, for example, so the sides of reflector 42 are substantially concealed by the cornice from the view of a person standing in front of the showcase. It will be obvious that if the showcase is of sufficient length a plurality of light tubes l1 may be mounted in the reflector in axial alignment.

Starting from the top of curved edge l5, as seen in Fig. 3, reflector i2 has a horizontal section I8 which extends outwardly into contact with the rear surface of front glass 2 adjacent its upper edge. The reflector then extends upwardly in a plane parallel to the inside surface of front glass 3 to form a vertical section is curved at 20 to extend horizontally towards curved edge It. This horizontal section, designated by the numeral 2!, lies in a plane parallel to but spaced below the plane of top glass plate l. Curved edge 58 merges into a horizontal section 22 parallel to and engaging the bottom surface ofglass plate 4. A short vertical section 23 connects horizontal sections 2| and 22.

Section of the reflector extends forwardly of section 23 so as to provide a space or recess 2 3 between sections El and 22, closed at one side by vertical section 23 and open at the opposite entrance side. portion of section 22 extending forwardly of section 23 is provided with a threaded aperture 25 and section 2! has a counterbored aperture aligned therewith.

Reflector it; may be extruded or drawn as a unit, or it may be formed of sheet metal bent to shape. In the latter case, curved edge [6 may be formed separately and welded to vertical section 23,. Section may be provided with one or more apertures 2? so that the electrical wiring (not shown) can enter the space above sec tion 2 l.

The cornice comprises a rounded section 28 having its top extending horizontally and flush with the top surface of top glass plate Rounded portion 29 has a lateral extension 3% at each end fitting into notches i in end walls to cover the tops of channels The depth of notches i is equal to the thickness of extensions 3% so that the top surface of the extensions will be flush with the adjacent surfaces of the showcase.

The rear edge of rounded section it terminates in a downwardly extending vertical section 3! which engages the front edge of top glass plate A when cornice 28 is assembled with the showcase. A flange 32 extends horizontally from the bottom of vertical section ti and fits into space 23. Flange 82 is provided with an elongated aperture 33 that is aligned with apertures and 2s when cornice 23 is in its proper position. A metal screw 3 may then be inserted in apertures 26 and 33 and screwed into aperture 25 to hold cornice 23 in place.

The lower edge of rounded section 253 of the cornice terminates in a horizontal section 35. A vertical flange it extends downwardly from section 35 in contact with the front surface of the upper edge of front glass plate 3. Figure a shows how flange and vertical section iii of reflector 28 cooperate to hold the top edge of front glass plate 3 firmly in proper position.

When cornice 2S secured to the showcase the space defined by the inner surface of rounded section 29, vertical section 3 i, and sections i9, 23 and 2t of reflector 553, forms a safe conduit for carry ing the electrical wiring from the current source to light tube ii. If the wiring has to be inspected or repaired it is accessible by merely loosening screw B t and pulling cornice 2S outwardly to remove fiange from the recess in reflector :2.

When front glass plate 3 must be replaced, cornice 28 is removed in the manner described in the preceding paragraph. Section 22 of the reiiector furnishes adequate support to top glass =5 because the reflector is rigidly supported at its ends by mortise plates 8. Accordingly, it is not necessary to disturb top glass plate '3 in any manner when the front glass plate is to be replaced. The edges of the new glass plate 3 are inserted in channels t and the glass is then slid downwardly into position. Cornice Bil is then replaced and screw 3 tightened to hold it in place.

In the embodiment illustrated in Fig. 5, the shape of reflector 3'1 follows generally the shape of reflector l2 and the reflector is secured to ends 5 of the showcase in the same manner as previously described. The lower curved edge 38 terminates at its upper portion in a horizontal section 39 provided with a threaded aperture 40. Section 39 is bent at right angles to form a vertical section 4! provided with a threaded aperture 42. Section 4: is curved to meet a horizontal section .3 having a threaded aperture 44. Horizontal section 43 merges into the upper curved edge 45.

The rear surface of the top edge of front glass plate 3 is held in place by a wooden stop 46 secured to the underside of section 39 by a screw threaded through the wooden stop and into aperture 40. An angle iron 48 has one upwardly directed leg secured to section 41 by a screw 49 threaded therethrough and into aperture 42. The other leg 58 of angle member 43 is downwardly directed in offset relation with respect to the first mentioned leg, and is in contact with the front surface of front glass 3. Tightening screw 49 pulls leg 59 towards stop 46 to hold the top edge of front glass plate 3 rigidly therebetween.

Cornice 5| has a rounded section 52 that terminates at its lower edge in a horizontal section 53 and at its upper edge in a horizontal section 54. Section 53 fits underneath the forwardly extending edge of the horizontal section of angle iron 48 which joins leg 50 and the other leg. Section 54 of cornice El terminates in a vertical section 55 which extends downwardly into engagement with the top surface of section 43 of reflector 3'1. A flange 53 extends rearwardly in a horizontal plane from the bottom of section 55. Flange 5E; rests on the top surface of section 43 of reflector 37 and is secured thereto by a screw 5? which extends through an aperture in flange 555 and is threaded into aperture 44.

The front edge of top glass plate l rests on flange 56 and is supported thereby. In this embodiment the top glass must be removed before access may be had to screw 51 which must be removed before cornice 5! can be removed. A conduit for carrying electrical wires is provided by the space between cornice 5| and reflector 31. Section 4! is provided with an aperture 58 to permit the wiring to pass from the light socket to the conduit. The front glass plate 3 may be replaced and wiring may be inspected or repaired, after cornice 5| has been removed, without disturbing the reflector 3'5.

Although I have described two preferred embodiments of the invention in considerable detail, it will be understood that the description is illustrative, rather than restrictive, as many details of construction may be modified or changed without departing from the spirit or scope of the invention. Accordingly, I do not desire to be restricted to the exact structure described.
