Description
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 of tools 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. 1 there is
shown a rotary sunglass display stand 10 including a pedestal 12.
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 18. 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 12 and
held in place by collar member 13 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 12
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. 5 - 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 FIG.
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
side-wall 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 stem 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 stem 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 sunglass 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 70 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 stem 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 upwardly
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.
