Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to display cases and, more particularly, to
a novel display apparatus for mounting a plurality of removable
name strips employing grooved extruded side sections having
opposing slots cooperating to support the strips in an assembly,
support a hingable glass door, and retain the various electrical
components in a modular unitary construction.
2. Description of the Prior Art
In the past, it has been the conventional practice to provide
directories with a case for holding letters or lettered strips in
an orderly sequence. The case is bulky and requires installation
into a wall cavity for mounting and attachment to the wall.
Obviously, construction of a suitable wall cavity and installation
of the case is time consumming and uneconomical.
Furthermore, conventional directories require that the case and its
component parts must be taken apart in order to remove or
substitute name or lettered strips. Generally, a tongue and groove
construction interconnects the strips or mounts the strips to the
case. Removal or replacement requires proper alignment of the
components so that one will slide or move into connection or
engagement with the other component.
Therefore, there has been a long standing need to provide a new
display means for holding a plurality of names that may be readily
seen regardless of adverse lighting conditions and that is composed
of modular components cooperating with one another so as to reduce
the number of parts and ease of assembly and disassembly.
SUMMARY OF THE INVENTION
Accordingly, the above problems and difficulties are obviated by
the present invention which provides a novel display case for
holding a plurality of strips so that lettering formed on the
strips is readily visable. The individual strips are removably
carried in opposing slots formed in side extrusion sections forming
these sides of the case while a back panel forms the back of the
case and top and bottom sections, identical to the side extrusion
in cross section, form the top and bottom of the case. The side
extruded sections further include opposing slots which support a
hingable door means carrying a transparent panel for protecting the
name strips. The name strips are carried on an assembly with side
retainers and a translucent panel. Illuminating means are carried
on the back panel in close proximity to the translucent member so
that light is cast behind the name strips whereby the lettering on
the strips is illuminated and made visable thereby.
A feature of the invention resides in the forming of the identical
side sections and top and bottom sections as an extrusion so that a
one piece construction is produced serving a variety of functions.
By providing the extruded sections, assembly and disassembly of the
components parts is greatly simplified and the utility of the
invention greatly enhanced.
Therefore, it is among the primary objects of the present invention
to provide a novel display case for lettered strips wherein the
letters are readily made visible under adverse lighting
conditions.
Another object of the present invention is to provide a novel
display case or apparatus for removably supporting a plurality of
lettered strips in a removable assembly which includes extruded
components adapted to retain and support a variety of component
parts.
Another object of the present invention is to provide a novel means
for supporting a plurality of name strips on top of one another in
an assembly so that the strips give the appearance of a solid panel
and yet these strips are individually removable from the
assembly.
Another object of the present invention is to provide a novel
extruded section or component adapted to support a variety of
modular components when a pair of such extrusions are arranged so
that openings and slots formed therein are opposed to one another
for retaining the opposite ends of the component parts.
Yet another object of the present invention is to provide a novel
display case for assembly and installation on a flush wall of a
building so that a plurality of removable name strips are readily
visable and wherein the construction includes specially extruded
sections for retaining and holding the various component parts of
the apparatus.
A further object resides in providing a relatively slim display
case that may be directly mounted onto the exterior surface of a
supporting wall.
The features of the present invention which are believed to be
novel are set forth with particularity in the appended claims. The
present invention, both as to its organization and manner of
operation, together with further objects and advantages thereof,
may best be understood by reference to the following description,
taken in connection with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring now to FIG. 1, the display apparatus of the present
invention is illustrated in the general direction of arrow 10 which
includes a case mounted on a wall 11 such as in the main lobby of
an office building so as to display the names and titles of the
occupants. The names, titles and room number of the occupants are
carried on a plurality of strips such as the strip identified by
numeral 12 lying immediately behind a glass cover 13 which is
partially broken away to expose a portion of the strips. The glass
cover 13 is composed of smoked transparent material and is held in
a frame identified in general by the numeral 14 which is composed
of four identical extrusion members. The case further includes a
back panel 15, a bottom section 16 and a top section 17. To
complete the over-all construction of the case per se, extruded
side sections 20 and 21 are included which serve to support the
door, the plurality of name strips and other components of the
assembly. The sections are all identical in cross section so as to
form a rigid outer frame.
Referring now in detail to FIG. 2, the door carrying the protective
smoked transparent glass 13 is open to expose the plurality of name
strips 12 therebeneath. It can be seen that immediately behind the
name strips, there is provided an illuminating means constituting a
pair of fluorescent light tubes 22 and 23 which are arranged to
provide light behind the plurality of strips. A starter 24 and a
ballast 25 are of conventional design and are included in the
circuit for controlling the illumination means. These later
elements are carried on the extruded side section 21 as will be
explained later. Disposed between the illumination means 22 and 23
and the plurality of strips 12, there is provided a translucent
panel 26 which functions as a sight trap for concealing the
fluorescent tubes 22 and 23 and yet permitting light rays or
illumination from the tubes to radiate evenly outward to the
plurality of name strips.
Referring now in detail to FIG. 3, it can be seen that the
plurality of strips 12 are located in spaced relationship between
the transparent panel 13 and the translucent panel 26. The strips
are held in an assembly at their opposite ends in insertable
relationship with a pair of elongated retainers 30 and 31 that are
of U-shaped configuration in cross-section. The retainers are
adhesively secured to the surface edges of panel 26. In combination
with an extruded partition 32 a slot is defined for receivably
retaining the upper and lower edge marginal regions of the panel 26
so as to be removably secured to the outer frame. The extruded
partition is indicated by numeral 32 with respect to extrusion side
section 20. It is to be understood that the extrusion side section
20 and 21 are identical and therefore, for clarity, extrusion side
section 20 will be described. The extrusion comprises a base wall
33 forming the exterior side of the outer frame and integral
partitions such as wall partition 31' extend outwardly therefrom at
a right angle. In spaced apart relationship from wall partition 32,
there is provided an integral thickened portion 34 that includes a
longitudinal slot that may be employed for receiving screws, bolts
or the like so as to retain the top and bottom sections onto the
case. Also, each extruded side section includes a wedge shaped slot
such as is indicated by numeral 35 that may be used for receiving
other components and parts. For example, wedge shaped slot 35 is
employed for receiving a coaxial-pivots 36 carried on plates 37 and
39 which the door is rotatably carried. Plates 37 and 39 are
mounted in a similar wedge shaped slot carried on the frame 14 of
the door and section 16. The wedge shaped slot carried on similar
extruded side section 21 is employed for retaining a leaf spring 38
which is more clearly shown in FIG. 4.
FIG. 4 further illustrates that the seat, indicated by numerals 40
and 41 at the opposite ends of leaf spring 38 are slidably received
within the wedge shaped slot formed in the extrusion side section
21. Also, the case is provided with a pair of reflectors designated
by numerals 42 and 43 which are angularly disposed between the
illumination means and the extruded side sections. Light from the
illumination means is reflected from the elongated surfaces of the
reflectors 42 and 43 to enhance the visability of the letters and
names carried on their respective strips 12. The side extrusion
section also includes a portion rearward of the wall partition 32
that includes an integral brace having opposing shoulder portions
44 adapted to receive a L-shaped bracket 45 for holding the joining
corners of the outer frame extrusion sections. It is to be
understood that the same construction is employed with respect to
extruded side section 21. Furthermore, the extruded side section is
of reduced width at the rear and includes a flange member 46
providing a support or retainer for securing the back member 15
thereto.
FIG. 5 more appropriately shows the hinge or pivot means for the
door and its swing mount on the bottom panel 16.
Referring now to FIG. 6, an enlarged view of strip 12 is shown
wherein the top of the strip is in a V-shaped configuration
identified by numeral 50 while the underside of the strip is
illustrated as having a wedge shape indicated by numeral 51.
Therefore, it can be seen that the respective strips may be nested
on top of each other as is illustrated more clearly in FIG. 7 to
eliminate any light leaks between strips. In FIG. 7, strip 12 may
be readily removed by manually moving strip 12 upwardly to the
position shown in broken lines so that the underside of strip 12
may be readily grasped and pulled outwardly so that either of its
opposite ends may dislodge from its slidable insertion with
U-shaped retainer 30 or 31, respectively. Once the strip has been
removed, any strips on top of it may be lowered to rest on the then
upper most strip in the stack.
Therefore, it can be seen that the novel display case of the
present invention provides a unique manner for constructing,
assembly and holding a plurality of name strips so that they may be
readily changed and that once installed, they may be made visable
for reading purposes, when engraved with the appropriate means
and/or other information. Also, the employment of extruded side
sections greatly aid in the assembly of the device as well as the
construction thereof since predetermined grooves, slots and walls
are formed integrally thereon. When the door has been opened, the
name strips may be removed as a unit by removing the top of
retainers 30 and 31 from the slot in section 17 and drawing the
assembly out through the opening and then lifting the assembly to
remove the bottom of the retainers from the slot in section 16.
While particular embodiments of the present invention have been
shown and described, it will be obvious to those skilled in the art
that changes and modifications may be made without departing from
this invention in its broader aspects and, therefore, the aim in
the appended claims is to cover all such changes and modifications
as fall within the true spirit and scope of this invention.
