DISPLAY DEVICES
Abstract
A display device for changeable signs having a transparent cover
for receiving therein in upright position the changeable cards
carrying suitable indicia. The cover is enclosed on all sides
except the bottom, where it receives a bracket and which
substantially fits in the opening to seal the latter against the
entrance of foreign substances. The cover is frameless and formed
of relatively thin walls which overlap the bracket at the bottom.
Ears are formed on the opposite end walls at the bottom extending
substantially throughout the width of the cover and in position to
be seated upon the bracket. The ears are internally threaded to
receive fastening screws detachably connecting the cover with the
bracket and which can be inserted through openings in the bracket
into the threaded openings in the ears.

Description
OBJECTS AND DESCRIPTION
The invention relates to improvements in display devices for
holding changeable cards or signs.
In the merchandising of various commodities, for example gasoline,
signs are employed denoting the price thereof and which are usually
displayed in the open being attached to the gasoline pump or other
support for observation. Inasmuch as the signs or cards are usually
constructed of paper, cardboard or other printed material, it has
been the practice to enclose them in suitable holder to protect
them from the weather.
A mounting bracket is attached to the cover and supports the latter
in secure position thereof. The mounting bracket, in turn, may be
supported on a gasoline pump or other point of support.
An attempt has been made heretofore to use a frameless transparent
cover for accommodating the cards. This has involved relatively
thick walls with fastening members embedded in the end walls of the
cover. Not only is the heaviness of construction objectionable
because of the incidental thickness of the walls, but the insertion
of fastenings in the walls weakens the latter and causes these to
break and result in insecure attachment of the cover to the
bracket.
One object of this invention is to overcome the foregoing
difficulties and disadvantages in a frameless transparent cover and
to improve the construction of the display holder.
Another object of the invention is to provide a cover with
relatively thin walls of uniform thickness and attaching means
thereon which will securely connect the cover with a supporting
bracket adapted for ready replacement when needed to change or
replace the display cards.
These objects may be accomplished, according to one embodiment of
the invention, by constructing a cover of relatively thin
transparent material as a self-contained frameless structure. The
cover is adapted to receive therein changeable exhibitors such as
display cards which may be replaced or changed at frequent
intervals. Each change would require the separation nd removal of
the cover from the mounting bracket, but when in place on the
mounting bracket, the cover forms a sealed connection with the
bracket to exclude dust and foreign particles therefrom.
The relatively thin end walls of the cover, of uniform thickness,
have formed in one integral piece therewith ears located on the
outside of the cover at the bottom in positions to be seated upon
the mounting bracket. Each of the ears extends substantially
throughout the width of the cover and extends outwardly from the
adjacent end wall a substantial distance, more than half the
thickness of the cover. Each ear is internally threaded to receive
a detachable screw, preferably with wings that can be turned by
hand, inserted through the bracket and into the opening formed in
the ear for securing the cover tightly upon the bracket.
The embodiment of the invention is illustrated in the accompanying
drawings, in which:
FIG. 1 is a side elevation of the cover and mounting bracket;
FIG. 2 is an end elevation thereof;
FIG. 3 is a cross section on the line 3-3 in FIG. 1;
FIG. 4 is an upright section through one of the ears and a portion
of the mounting bracket on the line 4-4 in FIG. 2; and
FIG. 5 is a cross section through the sidewalls and mounting
bracket on the line 5-5 in FIG. 1.
In this embodiment of the invention, we have shown suitable
mounting bracket 1 for supporting the cover in an upright position,
as for example, upon a gasoline pump of similar dispenser. The
bracket 1 illustrated in the drawings has upper and lower arms 2
and 3 formed substantially in U-shape, the arm 3 having suitable
openings 4 for securing the bracket upon the gasoline pump or other
support. The arm 2 has openings 5 therein adjacent its opposite
ends to receive fasteners for the cover, as hereinafter
described.
The cover is indicated generally at 6. This cover is formed of a
suitable transparent plastic material capable of molding or
fabrication, as desired, so as to form a substantially one-piece
construction.
The cover 6 includes a top wall 7, opposite end walls 8 and
sidewalls 9. These walls are generally thin, ordinally less than
one-eighth inch in thickness, and of uniform thickness. The
sidewalls 9 are spaced apart at the lower edge of the cover a
distance substantially equal to the width of the top section 2 of
the bracket so as to fit snugly on opposite sides of the bracket
when the cover is seated thereon. The sidewalls 9 are provided with
depending flanges 10 to embrace the section 2 of the bracket in
tight-fitted relation, as illustrated in FIG. 5, when the end walls
8 are seated upon the top face of the bracket.
Formed in one integral piece with the cover 6 are a pair of ears 11
disposed outwardly of the end walls 8 at the lower ends of the
latter. Each of the ears 11 is preferably molded in one integral
piece with the body of the cover 6 when the latter is molded so as
to form a one-piece construction with a secure connection between
the ear and the cover. Each ear 11 preferably is of a size which
extends throughout the width of the end wall 8 and may be
semicircular in cross section. The ear 11 projects outwardly from
the adjacent end wall 8 a distance greater than one-half of the
width of the ear and the width of the end wall so as to form a
substantial projection on the outer face thereof at its lower end.
The length of the ear 11 should be sufficient for secure connection
of the adjacent side of the cover 6 to the bracket 1.
The ear 11 is internally threaded, as indicated at 12, to receive
therein a screw fastening 13 which extends through an orifice 5 in
the section 2 of the bracket into threaded connection at 12 with
the ear 11. Wings 14 on the screw 13 enable the screw to be turned
by thumb pressure, thereby facilitating the insertion and removal
of the threaded fastening.
We have illustrated a conventional display card or changeable
exhibitor at 15 located within the cover 6. This is preferably of
the type usually employed for displaying the price of gasoline,
having indicia thereon in terms of whole numbers and fractions as
ordinarily employed for this purpose. Any other suitable or desired
form of changeable exhibitor may be employed within the cover.
The display cards or exhibitor 15 will need to be replaced or
changed whenever there is a change in the price of gasoline. This
necessitates the removal of the detachable fastenings 13 and the
separation of the cover 6 from the bracket 1. When that is done,
the cover can be lifted off and the required changes made in the
display cards 15. Then the cover, with the changed display cards,
can be replaced on the bracket.
Inasmuch as these changes occur at considerable frequency, the
screw fastenings must be replaced each time a change is made in the
display material. This invention makes it possible for the
fastenings to be removed readily by hand and yet can be screwed up
into tight relation with the ears 11 so as to secure the cover
effectively upon the bracket 1. The size and character of the ears
11 and the means of connection therewith by screw fastenings
extending through holes in the bracket, not only provides an
effective and secure mounting of the cover on the bracket, but it
retains the connection with little danger of damage or breakage in
repeated use.
At the same time, the body of the cover is relatively thin and
transparent, which not only effects a saving in expense, but it
also makes a more attractive display holder which is entirely
frameless, but is effective for the purpose.
While the invention has been illustrated and described in one
embodiment, it is recognized that variations and changes may be
made therein without departing from the invention set forth in the
claims.
