SUNGLASS DISPLAY STAND BACKGROUND AND OBJECTS OF THE INVENTION One of the prime requisites for the successful merchandising of sunglasses on the retail level is an attractive display of the glasses allowing the purchaser to easily see and select the frame design of his choosing. For this purpose display stands have been utilized over the years of many different designs and materials. The most common type of these stands in use today are those of the vertical rotary type which stand on the floor or on counters. A substantial portion of these stands have been made of metal and the assembly of the stands, usually done by the sunglass manufacturer before shipment. have required time consuming use oftools for assembling the various parts. The cost of materials for the metal parts as well as the cost of labor for assembling them have provided an incentive for the present invention which reduces both of these expenses.
Another problem encountered by the older types of sunglass display stands is the limited number of sunglasses that can be displayed on the stands. The stands of course can only take a minimum of floor or counter space in a store where the overall display space must be carefully apportioned between the various items the store is merchandising. Thus many of the older stands display sunglasses with their temples open, and the like, failing to use the limited space available most efficiently. Since these stands can only hold a limited number of sunglasses, it is necessary to store extra glasses for back-up when the glasses on the stands are sold. The present invention provides, among other things, for the sunglasses displayed to have their temples automatically partly closed upon insertion of the sunglasses into the stand supported racks by either the loader in the factory or the customer after he has tried on the glasses and wishes to return them to the rack. This feature allows more sunglasses to be displayed in a given space and alleviates greatly the need for storage of back-up stock.
It is therefore an object of this invention to provide a sunglass display stand utilizing more recently developed materials such as plastics of high strength and excellent appearance for substantially all the components thereof. The components may then be molded reducing manufacturing costs. The high flexural strength of the plastic material is also utilized in certain unique manners for interlocking the components of the stand during assembly.
Another object of the invention is to provide a sunglass display stand which may be assembled quickly and almost entirely by hand without the use of tools.
A further object of this invention is to provide a display stand having structure to display a large number of sunglasses in a minimum of space.
SUMMARY OF THE INVENTION The foregoing and other objects are achieved in a sunglass display stand of the vertical rotary type. The stand has a standard pedestal base which may stand on the floor or on a counter depending upon the size of the display. A shaft extends upwardly from the pedestal providing an axis for rotation for the actual sunglass holding portions. These rotatable portions each consist of a display rack including a pair of end members called spiders because they preferably consist of a central hub portion having an opening for the shaft to pass through the center thereof and a plurality of legs extend outwardly from the hub. At the end of each leg is a specially designed slot for receiving the end portion of a one piece molded vertical rack column. The rack columns have attachment portions which snap into the slots in two aligned legs of the opposing spiders at each end of the rotatable display frames portions. These rack columns can be snapped into their receiving slots in the spider legs by manual pressure without tools and once snapped in place cannot be removed for all intent and purposes. Both the aforementioned spiders and vertical rack columns are preferably integrally molded elements of plastic materials chosen for appearance relatively low cost and high flexural strength required in such areas as the receiving slots on the spiders.
Each rack column is specially designed to receive a plurality of sunglasses one above the other and members are provided to receive the temple portions and support them and to support the glasses also at the bridge portion. These are cam members on the temple receiving portions to engage the temples and cam them closed as the sunglasses are inserted into the rack columns. By insuring that the temples are cammed closed more pairs of sunglasses can be displayed for a given diameter of the circular rack which is an advantage since back-up stock does not have to be stored separately. The bridge supporting members are also provided with structure including abutment means to limit the inward movement of the sunglasses and a flange to prevent them from slipping too far outwardly so the glasses are always supported properly and fixed in the position most advantageous for display.
Other objects and features of the invention will become apparent by reference to the following specification and drawings of the presently preferred embodiment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings and in particular to FIG. I there is shown a rotary sunglass display stand 10 including a pedestal l2. Extending upwardly from the pedestal is a shaft 14 which provides an axis of rotation 16 through the center thereof for the rotatable sunglass display racks l8. Deformed portion 20 of shaft 14 and washer 22 support the frame 18 at the desired height on the shaft 14. The shaft 14 extends through an opening in the pedestal l2 and held in place by collar member l3 and end cap 15.
The illustration in FIG. 1 shows only one display rack 18 rotatably mounted on shaft 14, which is used. for example, for a sunglass display stand which rests on a counter. Such a rack might also be supported on a wall using a special fixture including a vertical shaft such as shaft 14. For a floor display, a larger pedestal l2 and longer shaft 14 are provided and as many as three of the display racks 18 are rotatably supported on the longer shaft one atop another. The racks may be connected together by clips or any known means for mutual rotation or could conceivably rotate separately in spaced relation on the shaft 14.
The display racks 18 each include a pair of spaced identical end members 24 which are referred to as spiders because they consist of a central hub portion 26. as shown in FIG. 2, having an opening 28 through which shaft 14 passes through, and a plurality of legs 30 which extend outwardly from the hub. A cap 31 is slipped over shaft 14 to hold the upper end member in place. The end members or spiders are preferably integrally molded one-piece members formed of a synthetic plastic material. For the preferred embodiment high impact polystyrene has been chosen for its cost advantages, attractive appearance and high flexural strength. Other plastic materials fulfilling these minimum requirements may obviously be substituted.
The use of such plastic end members has many advantages including their ease of manufacture, light weight for shipment purpose, and visual attractiveness. In addition, the flexural strength of the high impact polystyrene plastic material is utilized in the unique attachment portions 32 provided at the end of each spider leg. A plurality of sunglass holding rack columns 34 are connected between the spiders 24 by means of these attachment portions which, as clearly shown in FIGS. 7, comprise a slot 36 formed at the end of each spider leg 30 and extending substantially the entire depth of the leg. The interior walls 38 of said spiders which form the slots are symmetrical on either side of the slot and shaped in cross-section as shown in FIGS. 6 and 7 to form an opening wider at the top and narrowing by means of converging walls 39 which lead into two small parallel vertical wall sections 37 at the narrowest portion of the slots and then widen abruptly to form a lip means 40 including a pair of substantially horizontal lips 41. The locking lip means cooperates with the attachment portions located at each end of the rack columns 34 in a manner described hereafter. The slots at each extremity thereof have substantially straight walls 33 as shown in FIG. 5. This allows for some needed play or freedom of movement upon insertion of the attachment portions of the rack segment into the slot. Further, the provision of ending the converging walls 39 short of the end of slots 36, as shown in H0. 3, allows the walls 39 to flex more easily, as required when the attachment portion are inserted into the slot.
The vertical rack columns 32. as shown in FIGS. 2 and 3, are all identical and each include an elongated stem portion 42 including a pair of side-wall members 44 and 46 extending substantially the entire length of the stem portion. Extending outwardly from the sidewall members 44 and 46 from opposite sides of the stem portion 42 at equal heights are a plurality of identical sunglass temple engaging support portions 48. The support portions 48 are symmetrical on each side of the stern member and each include a pair of laterally extending upper and bottom substantially horizontal members 50 and 52 joined by substantially vertically extending member 54. A pair of sunglasses 56 are supported for display with the temple portions 58 thereof in engagement with and supported by members 52, as shown in FIGS. 6 and 7. The inner surfaces 60 of member 54 are spaced a predetermined distance apart in order to serve as cam means to cam the sunglass temples into their closed position as they are inserted through the openings of the support portions 48. When the sunglasses are removed from the display stand by a customer, for example. while trying on a pair, the stern side wall members 44 and 46 serve as a cam means to cam the temples open enough to allow removal from the rack.
Extending forwardly from stem portion 42 are a plurality of front frame support members 62 each of which are located at a selected height with respect to the sun glass temple engaging support portions so that they can engage and support the bridge 64 on the front frame 66 of the pair of displayed sunglasses. Each front frame support member 62 includes a forwardly projecting elongated ledge 68 having a slight upward incline. The end of ledge 62 turns upwardly to form flange 70. The ledge 68 is further connected to stem portion 42 by a pair of side members 72 each extending only a portion of the length of ledge 68 and forming abutment means 73 including aligned shoulders 74 at the end of each member 72. As shown in FIG. 7 in particular, once the sunglasses are placed in position for display flange limits outward movement of the sunglass and bridge portion thereof while the abutment means 73 limits the inward movement thereof.
At the opposite ends of the stern portions 42 of each rack column 32 is an attachment portion 76 identical at both ends. Portion 76 includes an elongated member 77 which has a width closely conforming to the width of slot 34. Another member 78 extends from member 76, which as shown in detail in FIGS. 8 and 9, has a symmetrical configuration which is narrow at its outermost extremity 80 and then widens by means of diverging walls 82. Two parallel vertical walls 84 lead to a locking ledge means 86 including a pair of horizontal ledges 88.
In order to assemble the rack columns in position between a pair of opposed spiders legs 30 the portions 78 at each end of each column are inserted into the wide top portion of each slot 36 and then manual pressure is applied forcing the portion 78 inward until the horizontal ledges 88 are forced past the horizontal lips 41 in the slot walls. The flexural strength of the high impact polystyrene of which the slot walls are composed allow the slot walls to deform enough without breaking to allow the wider ledges 88 to slip through the narrowest portion of the slot. The resilience of the high impact polystyrene material then causes the material to return to its original position wherein the lips 41 are in locked position with the ledges 88 as shown in FIG. 8. Once in the locked position shown in FIG. 8 the two parts cannot be separated for all intent and purposes since it would require a force to shear off ledges 88 which would never be encountered under normal conditions.
Thus all the attachment portions may be locked within the slots on the opposing aligned spider legs as described above in the space of a minute or less in the hands of a skilled assembler and the frame 18 is then ready to be slipped onto the shaft 14 extending up wardly from pedestal 12 to complete the stand.
The number of legs on the spiders and number of rack columns extending between them depend of course on the allowable overall circumference of the display rack. For example. a counter stand may utilize seven-legged spiders while a floor stand which is of greater diameter may have as many as nine legs on each spider, On the larger floor stands the spiders may also be spaced further apart and the rack columns provided with a greater number of vertically spaced temple and frame support members than the smaller counter stands.
The end members which in the preferred embodiment are shown as spiders 24 may obviously omit the plurality of legs and instead be in the form of large diameter discs, for example, so long as they are provided with the appropriate number of slots spaced from the central openings therefrom so that they may be aligned for attachment of the vertical rack columns between them.
In a non-rotary version of a sunglass display stand the end members might take many forms, for example, there could be two opposing elongated strips having a plurality of opposing slots spaced along the lengths thereof with a pair of slots aligned on the top and bottom strips for receiving the attachment portions of the display rack segments. A suitable support means would be provided for supporting the assembled display racks on a counter. for example.
Since the end member and alike are interchangeable and since the vertical rack columns are all identical, a minimum number of molds or dies and only a few operations are required to manufacture and assemble the parts of the display stand.
The terms horizontal and vertical as used with regard to the above description refer to the orientation of the stands as they stand on the floor or counters in common use.
Thus it is clear from the above description that the sunglass display stand as described will fulfill the objects of the invention as stated and includes many features and advantages not heretofore available in such items.
