Abstract:
A table for displaying produce and baked goods and the like that includes a base and a tiltable table top pivotally mounted in the base. A series of collapsible shelves are pivotally mounted in the table top and are controlled by a detachable linkage so that the shelves remain in a horizontal position when the table top is tilted. Detaching the linkage allows the shelves to lie flat against the table top when the table top is tilted.

Description:
BACKGROUND OF THE INVENTION 
     This invention relates to a table for displaying goods to customers in a retail store and, in particular, to a table for displaying produce such as fresh fruits and vegetables, baked goods and the like, in a grocery department of a retail store. 
     Heretofore, most fresh fruits and vegetables, baked goods and the like, have been placed on display in stores either in bins or on flat tables. The produce on display is generally difficult to view and equally difficult to access when the goods are located to the back of the display table. Accordingly, unless the goods are constantly repositioned, those toward the back of the display tend not to be selected, go bad, and thus cannot be sold. 
     In an effort to move goods more efficiently, tables having tiltable tops have been developed which, when tilted upwardly, better display the goods and place the goods in a more advantageous, reachable location for the customers. Although the adjustable tables work quite well in practice, the amount of tilt that can be utilized is limited by the type of produce displayed. For example, when displaying round fruits or vegetables such as apples or oranges, the table is generally placed in a horizontal position. Even while displaying relatively flat fruits or vegetables, the amount of tilt must be relatively slight to prevent the goods from sliding off the table and being damaged. 
     SUMMARY OF THE INVENTION 
     It is therefore an object of the present invention to improve display tables used in grocery stores. 
     It is a still further object of the present invention to provide a display table for goods which contain automatically adjustable shelves which remain in a horizontal position as the table top is tilted into a raised position. 
     Another object of the present invention is to more effectively display produce, baked goods and the like in a grocery department of a retail store. 
     These and other objects of the present invention are attained by a display table having a support base and a tiltable top mounted thereon. A series of parallelly aligned shelves are pivotally mounted in the tabletop and are controlled through a latchable linkage mechanism so that the shelves remain in a level, horizontal position as the table is tilted.

     DESCRIPTION OF THE INVENTION 
     Turning initially to FIG. 2, there is shown a prior art display table 10 of the type generally found in the produce department or bakery of a supermarket. The table typically includes a rectangular base 11 for rotatably supporting a flat table top 12. The table top is hinged at one end 13 of the base so that it can be tilted upwardly as shown to display produce mounted thereon. A support stanchion 14 is pivotally mounted in the sidewalls the table top which includes notches to engage a dowel 17 mounted in the base to selectively position the table at various angles of with respect to the base. 
     As noted above, the prior art tables work well but are limited in use because the displayed goods tend to slide or roll off the table when the table top is tilted beyond a relatively slight angle. Any product that falls from the table becomes damaged and thus, cannot be sold thereby reducing the profitability of the business. Furthermore, items stored at the back of the table are hard to reach and thus do not sell as readily as those located at the front of the table. 
     Turning now to the remaining figures and initially to FIG. 1, the table 20 of the present invention is equipped with parallelly aligned shelves, generally referenced 33. As will be explained in greater detail below, the table is equipped with a control linkage that can be selectively engaged or disengaged at the option of the user for controlling the positioning of the shelves. When the control linkage is engaged, the shelves will remain in a horizontal position as the table top is tilted upwardly as shown in FIGS. 1 and 3. When the linkage is disengaged, the shelves will remain closed against the table top as the table is titled upwardly as illustrated in FIG. 4. 
     The present table contains a rectangular base section 25 having a frame consisting of a pair of stationary side bars 26, end members 27, and upright legs 28--28 for supporting the table on a substrate such as a grocery store floor (not shown). A table top 30 is hinged for rotation in the front of the base so the table can be easily raised to an inclined position as shown to FIG. 1. 
     The table top 30 consists of a pair of parallel side rails 31, each pivotally supported by pivot pins (not labeled, but similar to that previously described) in the front part of the stationary base 25. A plurality of collapsible shelves 33 are pivotally mounted between the side rails so that the shelves can lie flat against the rails to provide a flat rectangular surface upon which produce such as fruits and vegetables can be displayed. 
     As best illustrated in FIG. 8, each shelf 33 includes a pair of spaced apart end supports 34--34 which are angle irons having a horizontal leg 37 and a vertical leg 38. A series of spaced apart parallelly aligned wooden slats 36 are mounted upon the horizontal legs of the opposed end supports and are secured to the horizontal legs by any suitable means such as countersink screws on the like. The vertical leg of each end support is pivotally mounted in an adjacent side rail 31 by means of a pivot pin 39. Accordingly, each shelf can be tilted upwardly with respect to the front of the table top. 
     A rocker arm 40 is secured to the vertical leg of each end support by any suitable means so that the arm is substantially perpendicularly aligned with the horizontal leg of the support. The bottom portion of each rocker arm, in turn, is pivotally connected to a common control bar 43 by means of a pivot pin 44 so that each of the rocker arms are caused to rotate in unison when the control bar is displaced laterally beneath the table top. 
     Each control bar can be connected and disconnected from the base of the display table by means of an adjustable latching mechanism generally referenced 50 (FIG. 5). The latching mechanism includes a latch 51 that is rotatably retained to a front leg of the base. The latch is arranged to engage a latch pin 52 carried on the end of a threaded stud 53. The stud, in turn, is threaded into a housing 56 secured to the bottom of the control bar. The stud is held in a desired position by means of a pair of lock nuts 57 that close against the housing. The position of the control bar is set when the latch is engaged by adjusting the stud 53 within the housing 55. As shown in FIG. 4, when the latching mechanism 50 is disengaged, the shelves will lie flat against the rails as the table top is tilted between a horizontal position and the fully raised position, as illustrated. Engaging the latching mechanism, as shown in FIG. 3, pivotally attaches the control bar to the stationary table base, thus holding the shelves through means of the rocker arms in a horizontal posture, despite the position of the table top. Accordingly, the present display table can be selectively positioned to display a wide variety of goods to most effectively present the goods to a customer. 
     A pair of stanchions 59 having a series of notches 60 are hinged in the two side rails of the table top (FIG. 1). The notches are arranged to mate with dowels 63 mounted in the frame of the base. The tilt of the table top can thus be set to a desired position by selectively mounting an appropriate notch in mating engagement with the dowel. As should be evident from the disclosure above, with the latching mechanism engaged, the individual shelves will be held in a level horizontal position by the linkage mechanism as the tilted position of the table top is changed from one notch position to another. 
     The adjustable stanchions may be replaced by a hydraulic or pneumatic actuator 65 shown in FIG. 7. The actuator includes a double acting cylinder 66 containing a piston rod 67. The lower end of the cylinder is pinned to a rear leg of the base and the distal end of the piston rod is similarly pinned to one of the table top side rails. Fluid is exchanged via lines 68 to either side of a piston contained in the cylinder to selectively raise or lower the table top and thus set the table top at a desired position within the range of the cylinder. 
     A transparent plastic back plate 70 is attached to the rear slat of each shelf. The back plate is raised some distance above the floor of each shelf and thus prevents produce from falling off the back of the shelf when the shelves am being maintained in a horizontal position as illustrated in FIG. 3. Additionally, the back plates serve as stops to prevent produce from sliding down a tilted table top when the shelves are lying flat upon the side rails 31 as illustrated in FIG. 4. 
     A pull out drawer generally referenced 80 is slidably contained in the base so that it opens and closes at the front of the base. The drawer contains a front panel 71 and a pair of side panels 72. As illustrated in FIG. 6, each side panel contains a groove 74 that extends along its length that is adapted to slidably engage a tongue 76 mounted on the inside of each side bar 26 and thus support the drawer in the base. Spaced apart parallelly aligned wooden slats 77 are secured to the top of each side panel for supporting further produce when the drawer 80 is extended as shown in phantom outline in FIG. 3. 
     While this invention has been explained with reference to the structure disclosed herein, it is not confined to the details set forth mad this invention is intended to cover any modifications and changes as may come within the scope of the following claims:
