DISPLAY SYSTEMS OR DEVICES FOR SUBSTANTIALLY FLAT ARTICLES
Abstract
The invention contemplates a novel display device or rack with
supports and tray construction, which is adapted to be engaged by
pegs, studs, rods and like support means forming parts of the rack.
Such tray has a top face for retaining a swatch or sample of flat
material, article and the like and has further an underface or
bottom on which locking means in the form of fingers for retaining
and pivotally coupling the tray in the rack are accommodated. The
tray is first "pushed" into the rack for location and then "pulled"
into locking or snap position, in which each finger attached to the
rear or end wall of the tray comes to embrace a correspondingly
shaped rearward support for firm location thereon and for pivotal
movement thereabout. The forward support may determine the tray
inclination or angle assumed between rearward supports and forward
supports in the rack.

Description
SUMMARY OF THE INVENTION
The invention overcomes primarily undesirable disadvantages
generally inherent in display structures and tends to aim at a
reduction of the manufacturing cost and at a space saving
simplification of the conformation and installation of display
setups or trays, in particular for the use in connection with
carpet and like flat samples, or swatches of textile, cellulosic,
as well as plastic materials.
It is therefore one of the objects of the invention to provide
means facilitating firm anchorage and convenient removal of display
trays with respect to a display rack in a highly efficacious manner
accompanied by click or snap action of tray parts so that the
display trays may not be inadvertently or neglectfully dislocated
or shifted from their effective lodgement on the rack.
It is another object of the invention to provide means resulting in
a substantially concealed arrangement of locking means in the tray
body, so that the trays may be readily stacked and stored away when
not in use, protruding and accessory parts being effectively
avoided in this tray construction.
Still a further object of the invention resides in the provision of
means contributing to a very sturdy and impact-resistant display
carrier or like structure which has reinforcing ribs or like stays,
between which snap-action powered hook-shaped finger means are
arranged without presenting any protrusion or hindrance during
operation (insertion and removal) of the display carriers or trays
relative to the display rack.
The invention aims also at a special construction of the locking
finger means offering the possibility of being incorporated in
cabinet drawers, or other furniture pieces and generally in locking
devices where a certain resistance may be required to be introduced
or released before a final locking or unlocking operation can be
effectuated.
The invention contemplates also the provision of means conducive to
a very efficacious and space saving display equipment, which is
completely devoid of any metallic parts for the assembly thereof,
does not require any tools or accessories for its operation or
maneuverability to various (horizontal, angular or intermediate)
positions, and may be manipulated by unskilled labor without
endangering breakage of the display trays.
Yet a further object of the invention is the provision of means
contributing to a greatly improved and lightweight tray or carrier
structure of the type herein referred to, which allows unobstructed
exposure and examination of sample materials, especially of carpet
samples, as to their colors, patterns, quality of backing layers,
etc., and furthermore removal of samples from the carrier
structure, if desired.
Another important object of the invention is to provide means
envisioning easy enlargement and convenient mounting of the trays
or carriers on the display rack or like equipment.
These and other aims and objects of the invention ensue from the
following detailed description, which has reference to the attached
drawing, the latter being exemplary and explanatory of the
principles of the invention and being in no way restrictive
thereof.

DETAILED DESCRIPTION
Referring now more specifically to the attached drawing, there has
been disclosed in FIG. 1 a display equipment or rack 10, which
comprises a plurality of side panels or walls 11, 12, 13, and a
plurality of trays 15 later referred to in greater detail.
Sidewalls 11, 12, etc. have forward and rearward rows of support
means, such as pegs or rods 11a, 11b; 12a, 12b; 13a, 13b, etc.
These rows of pegs or tray supports may be differently arranged, if
desired, and the distance between the rows may be enlarged or
reduced depending primarily upon the respective size or dimensions
of the display trays employed. The rack 10 may have also a rear
wall 16, which in some instances, may be completely omitted or may
be so connected to the normal rack equipment 10, that it also
provides a greater depth. In this latter case, U-shaped extension
or projection parts may be removably attached to the rearward ends
of side panels 11, 12, 13, etc., and rear wall 16 will then be
connected to such rear extension or distance parts 17 which may be
e.g., telescopically added to the aforesaid sidewalls or panels for
achieving depth regulation for the rack equipment (FIG. 8).
Trays 15 together with all their parts may be injection molded and
possess a substantially flat underface 29a, and a flat surface 18,
which can be perforated as at 19 to further reduce the weight of
such trays considerably (only indicated at 19 in upper tray 15).
The forward edge 21 of tray 15 is clampingly received by U-shaped
retainer pieces or holders 20, 22 which are made of a suitable
plastic composition, which is transparent and can be force-fitted
onto the front tray edge 21 by means of corresponding prongs and
grooves, as indicated at 23, 24 (FIG. 6). These retainer pieces aid
in fixing and holding in position carpet and other flat swatches or
samples (not shown for the sake of clarity) on the surface 18 of
tray 15, especially when the tray or trays assume inclined
locations or placements on the pegs of the display rack 10, as seen
in FIG. 1.
The underface 29a of each tray 15 (FIGS. 2 to 7) is flat and has
offset walls, a rear wall 25 and opposite sidewalls 25b, depending
from the top surface 18 and defining the boundaries of the
underface of the tray. Between said walls extend lengthwise and
crosswise thereto longitudinal ribs 27b and transverse ribs 28b
each rib being partly indicated in FIG. 4 and serving to reinforce
the tray, but to allow for sufficient flexibility thereof.
Sidewalls 25b are each provided with a first or forward recessed
part 29 in which a pair of forward pegs 11a will be engaged when
the tray is inserted in display rack 10 by manipulation of the tray
from its front or forward edge 21.
At the rearward wall 25 of the tray near each lateral corner 25a
thereof there is arranged a rectangular-shaped reinforcing wall box
26 defined by relatively heavy walls 27. From each front end wall
27a of box 26 there projects a locking finger 30 which is of
predetermined width and has a relatively flat lower rear part 28a
connected to said end wall 27a. Each finger 30 has a cam-shaped or
angular front part 28 provided with a sharp ridge 31 (FIG. 3). The
surface of each locking finger with cam piece 28 underlies at a
predetermined distance the underface 29a with a cutout or slot 32
provided in and passing through the top surface 18 of each tray
approximately to the extent of each finger piece 30. The surface of
each locking finger piece 30 includes also a flat seat or niche 33
which is located rearwardly of angular or cam finger part 28 and
serves as a stall or rest for respective pairs of rear pegs 11b,
12b, 13b, etc. (FIG. 5) which in cooperation with the respective
slots 32 ensure a relatively smooth but tight fit in niches or seat
portions 33.
Sidewalls 25b present at a predetermined distance from rear wall 25
special guide means or notched sidewall portions, as shown in FIG.
3, each with an inwardly inclined edge 26a. Edge 26a defines
together with end wall 27a of open-ended box 26 and finger piece 30
a guideway or passageway 35 for the introduction or withdrawal of
the aforesaid rear pegs.
It is to be noted that sidewalls 25b, ribs 27b, 28b, box 26 forming
walls 27, 27a and fingers 30 are so disposed to each other that the
underface of tray 15 is substantially flush, is spaced from niche
or seat portion 33 a greater distance than from cam shaped portion
and does not offer any protrusions or projections. The tray is also
devoid of any metallic parts and as it is preferably made of
plastic material is light in weight, is sturdy, flexible and
resistant to impact even during rough handling by unskilled
labor.
As fingers 30 have sufficient yield or give relative to the
underface 29a of the tray, they are nevertheless strong and are not
subject ordinarily to breakage during operation. However, in order
to replace these fingers when inadvertently broken and in order to
avoid discarding of the trays, it is further proposed to replace
such finger 30 by a similar finger structure 40, (FIG. 7) which has
two end claw-shaped prongs 37, 38 integral with rear portion 36 of
finger 40. The finger with these prongs (similar to the prongs 23,
24 herein referred to) is so constructed that these prongs firmly
snap in or may be otherwise affixed in position in suitable grooves
or cavities 39 provided in front end wall 27a of box reinforcement
26. FIG. 7 illustrates finger 40 in the process of being attached
to wall 27a by means of prongs 37, 38 in opposite cavities 39
thereof (only one cavity 39 being visible).
Danger of breakage can readily be obviated by the employment of
fiberglass in reinforced plastic materials, nylon and like plastic
compositions.
The operation of the display equipment herein disclosed will be
easily understood. After a sample of suitable size is placed on the
surface 18 of tray 15 on which it will be retained by spaced
U-shaped holder pieces 20, 22 the tray may be pushed first from
forward edge 21 in the direction A onto a pair of selected rear
pegs, say, 11b which are then allowed to enter from a position
preliminarily engaging the underfaces of cam parts 28, then
respective inlets or passageways 35 whereby the inclined sidewall
edges 26a of the tray are guided along the respective rear pegs.
Upon subsequent pulling of the tray in the direction of arrow B
fingers 30 with ridges 31 will recede somewhat with respect to the
underface with slot 32 and will permit rear pegs 11b after having
passed cam parts 28 to snap into niches or recesses 33 forming the
seats of the respective fingers and to become firmly retained and
locked therein, but being allowed to permit pivotal movement of the
tray. Only after renewed pushing action of the tray in the
direction A can a disengagement of pegs 11b be had from finger
recesses 33 and of the fingers themselves, whereby the pegs slide
along inclined edges 26a and away from the fingers 30 for release
from the latter and from the aforesaid ridges 31 thereof. During
these "push and pull" movements of tray 15 the latter performs a
relative displacement whereby rear pegs or rearward support means
assume respective lodgements at 11c, 11d (FIG. 2). Front pegs or
forward supports 11a facilitate guidance and support of the tray 15
along first guideways or passageways 29, as it becomes quite
apparent from FIG. 2.
A lifting or sliding of the tray 15 and removal from its uncoupled
rack locations at 11a, 11b may then be had and, if desired, the
tray may be again engaged by different pegs to change the initial
horizontal to any desired inclined position, respectively.
In some instances, it may be found advantageous to manufacture the
sidewalls of the rack or like display equipment integral with their
pegs or studs 11a, 11b; 12a, 12b; 13a, 13b, etc. from plastic
material. These sidewalls of the rack may have also perforations to
receive tray support means, e.g. pegs, studs or even rods placed in
opposite openings (not shown) of the side panels 11, 12. All these
and other modifications of the invention are covered by the latter
in its broader aspects and the invention is not considered to be
limited to the specific embodiments herein shown and described.
Departures of any sort may be had without deviating from the
principles of the invention and without sacrificing its chief
advantages.
