FIG. 2 is a view in side elevation, some parts being broken away and some parts being shown in section;

DETAILED DESCRIPTION In the embodiment of the invention illustrated in-FIGS. 1- -4, a double-sided floral display cabinet is shown as comprising an open-topped rectangular casing 1 having a generally horizontally disposed bottom wall 2, opposite generally vertical end walls 3 and 4, and laterally spaced vertical longitudinal walls 5, 6 and 7. Preferably, the casing l is made from sheet metal, the bottom wall 2, end walls 3 and 4 and longitudinal walls 5 and 7 being preferably hollow and filled with suitable heat-insulating material 8. As shown, the longitudinal wall 6 comprises a pair of laterally spaced wall elements 9 and 10 that extend upwardly from the bottom wall 2 above the level of the tops of the longitudinal walls 5 and 7, the wall elements 9 and 10 having a plurality of vertical transverse partition elements 11 which divide the space between the wall elements 9 and 10 into a plurality of vertically extending air passages 12.

As shown in FIGS. 24, the partitioned elements 11 extend upwardly above the upper edges ofthe wall elements 9 and 10. With reference particularly to FIGS. 2 and 4, it will be seen that the longitudinal walls 5 and 7 are formed to provide laterally inwardly projecting top lips 13 that extend substantially the full length ofthe casing l.-

A pair of cross-sectionally L-shaped merchandise-supporting trays I4 and 15 are disposed in the casing I, one between the longitudinal walls 5 and 6'and the other between the longitudinal walls 6 and 7, the trays l4 and I5 extending the full length ofthe casing 1 between the end walls 3 and 4 thereof. Each tray 14 and 15 includes a generally horizontalportion 16 disposed in upwardly spaced relationship to the bottom wall 2, and a generally vertical side portion 17 disposed in inwardly, spaced parallel relationship toits adjacent one of the longitudinal walls 5 and 7. Preferably, and as shown particularly in FIG. 3, the bottom portions 16 are of double-walled construction, having a corrugated reinforcing member 18 between thev walls thereof. They tray bottom and side portions 16 and I7 cooperate with their adjacent longitudinal casing walls 5 and: 7, the end walls 3 and 4, longitudinal, wall 6 and bottom wall 2, to define a pair of plenums I9 and 20. As shown in FIGS. 2 and 4, the upper longitudinal edges of the side portions 17 are downwardly spaced from the upper ends of their adjacent longitudinal casingwalls 5 and 7 and the inturned lips 13 thereof, the upper edges of the side members 17 cooperating with the lips 13 to provide air inlet openings 21 and 22 to the plenums. I9-and 20 respectively. The bottom portions 16 of the trays l4 and 15 are welded or otherwise rigidly secured to the interior surfaces of the end walls 3 and 4 and to the wall elements 9 and 10 of the longitudinal wall 6, the side members 17 being supported by a plurality of longitudinally spaced brackets or the like 23 that are welded or otherwise rigidly secured to the intumed lips 13.

Cooling means for the cabinet is in the nature of conventional and well-known refrigerator mechanism including a condenser and compressor unit 24 mounted on one or more supporting means 25 that extend longitudinally outwardlyv from the cabinet adjacent the end wall 4 thereof, one of thebeams 25 being shown in FIG. 3, and a plurality of evaporatorunits 26 and 27 mounted in the plenums l9 and 20, respectively. The condenser and compressor unit is disposed within a generally rectangular cover 28 having a flat top 29 which serves as a display platform for merchandise. The evaporator units 26 and 27 each include cooling coils 30 disposed within a housing 31, each housing 31 having an air inlet opening 32 to its respective plenum l9 and 20. Each evaporator 26 and 27 has an air outlet 33 opening into the lower end of a difierent one of the airpassages 20 in the longitudinal wall 6, one of said outlet openings 33 shown in FIG. 4. With reference to FIG. 1, it will be seen that the evaporator units 26 are associated with every other one of the air passages 12, the evaporator units 27 being associated with alternate ones of the air passages 12. The several evaporator units 26 and 27 are operatively connected to the condenser and compressor unit by fluid conduits 34, in the usual manner.

Cooling air is circulated through the cabinet by a plurality of motor driven blowers or fans 35, one of which is shown in FIG. 4. Preferably, the blowers 35 are disposed in the inlet 7 openings 32 of each operator-units 26 and 27, and draw air into their respective evaporator units 26 and 27 from their respective plenums 19 and 20. From the blowers 35, air flows over the evaporator coils 30 and upwardly through the air passages 12 to the open top of the longitudinal wall 6. Deflector elements 36 and 37 are mounted to the upper end portions of the partition elements I1 and direct the flow of cooled air laterally outwardly and downwardly over merchandise, such as cut flowers or pottedplants, on the trays l4 and 15 and toward the air inlet openings 21 and 22 to the plenums l9 and 20, respectively. With reference to FIGS. 1-3, it will be seen that the deflector elements 36 and 37 are coextensive in length with the longitudinal wall 6. The wall elements 9 and 10 of the longitudinal wall 6 are each provided with a plurality of longitudinally spaced openings 38 just above the tray portions 16 to permit some of the cooled air flowing upwardly through the passages 12 to escape laterally outwardly to the lower portions of merchandise, not shown, on the trays l4 and 15. Air flowing outwardly through the openings 38 flows laterally outwardly and angularly upwardly toward the air inlet openings 21 and 22, as shown by dotted arrows in FIG. 4, the main airflow being generally indicated by solid arrows in FIG. 4. Thus, a continuous flow of cooled air is maintained over and through the merchandise supported on the trays l4 and 15, fresh air being continually drawn in through the air inlet openings 21 and 22 together with the recirculated air flowing from the deflector elements 36 and 37 to the plenum air inlets 21 and l 22. Control of the air temperature is maintained in the usual manner by a thermostat, not shown, but placed in an ad-' vantageous position within the cabinet. Preferably, the temperature of the air flowing through the cabinet is maintained at approximately 429E, at which temperature floral merchandise is kept in a fresh healthy condition.

A plurality of drains 39 extend upwardly through the bottom casing wall 2 for the purpose of receiving condensate from the plenums I9 and 20, the drains 39 being connected to a conduit 40 that extends to an evaporator tray 41 at the bottom portion of the condenser and compressor unit 24. Evaporation of the condensate in the tray 41 promotes effi- 'cient operation of the condenser and compressor unit, the evaporated moisture being discharged outwardly of the cover 28 through one of a pair of grill-equipped openings 42 therein,

one of which is shown in FIG. 2.

As shown in FIGS. 2-4, the longitudinal wall 6 is provided with a plurality of longitudinally spaced vertically elongated transverse tubes 43 that define sight openings 44 through the longitudinal walls 6, whereby at least a portion of the merchandise supported on one of the trays 15 may be viewed from the opposite side of the cabinet.

In the modified form of cabinet illustrated in FIGS. 5 and 6, an open-topped casing 45 is shown as comprising a horizontal bottom wall 46, opposite end walls 47 and 48, and laterally spaced longitudinal walls 49 and 50, the latter of which comprises spaced wall elements 51 and 52 having longitudinally space vertical partitions 53 therebetween defining a plurality of vertical air passages 54. As shown in FIG. 6, the longitudinal wall extends upwardly of the level of the top of the longitudinal wall 49, and at its upper end is provided with longitudinally extending deflector elements and 56. The upper longitudinal edge portion or top of the wall 49 is formed to provide a laterally inwardly projecting lip 57. A merchandise receiving and supporting tray 14, similar'to the tray 14, is disposed within the casing 45 and supported by one or more bracket elements 23'. Like the tray 14, the tray 14' cooperates with the several walls of the casing 45 to define a plenum 19' in which is mounted a plurality of longitudinally spaced blower-equipped evaporator units 26 having air inlets 32' communicating with the plenum l9 and cooled air outlets 33 each communicating with a different one of the air passages 54. The side portion 17' of the tray 14 has an upper edge disposed in downward spaced relationship to the inturned lip 57 to define therewith an air inlet opening 21' to the plenum 19. The wall element 51 is provided adjacent the tray bottom portion 16 with a plurality of longitudinally spaced openings 38', one of which is shown in FIG. 6, for the same purpose as the openings 38 in the longitudinal wall 6. The wall element 52, like the bottom wall 46 and longitudinal wall 49, is of double-walled sheet metal construction with heat-insulating material 8 therein. A container or cover 58, adjacent the end wall 48 encloses a condenser and compressor unit, not shown, for the evaporator units 26'. The cabinet of FIGS. 5 and 6 operates in the same manner as that of FIGS. 1-4, cooled air being forced upwardly through the vertical air passages 54 and deflected angularly outwardly and downwardly by the deflector elements 55 and 56 toward the air inlet opening 21' to the plenum 19. Further, some of the air flowing upwardly through the passages 54 flows outwardly through the openings 38' and angularly outwardly and upwardly therefrom toward the air inlet opening 21, as shown by dotted arrows in FIG. 6, the main flow of air through the cabinet being shown by full arrows in FIG. 6.

The form of cabinet illustrated in FIGS. 1-4 is adapted to be placed in an area where persons may have easy access to both sides of the cabinet, whereas the form of cabinet illustrated in FIGS. 5 and 6 is adapted particularly to be placed against a wall or like partition. The cover 58 is provided with a flat top 59 for display of merchandise placed thereon.
