TECHNICAL FIELD
[0001] The present invention relates to a display device, and in particular, to a rotating
display device, particularly suitable for, but not limited to, a rotating menu board
for use in a fast food restaurant.
BACKGROUND OF THE INVENTION
[0002] Menu boards used in fast food outlets are typically positioned at more than two meters
above ground level, usually behind and/or above the serving counter, or, in a driveway
- for a drive-through service. The difficulty encountered with utilising such menu
boards is that they are difficult and cumbersome to change, due to their size and
position.
[0003] Also, in some fast food outlets, two or more menus are often utilised throughout
the day, for instance, at breakfast or at lunch and/or dinner. With such prior art
menu boards, fast food outlets with two or more menus typically show both their menus
throughout the entire day. This causes delays, confusion and misordering by customers,
when looking at the wrong menu.
[0004] Various rotating menuboards have herebefore been designed, to overcome these problems,
such as described in Australian Patent No. 640211 by Florida Plastics Midwest, Inc.
AU 640211 describes a rotatable display sign which has a circular-like member 56 (Fig.
7) with a plurality of recessed portions around the circumference thereof. A plurality
of rigid panel portions 34 which are interconnected on their longitudinal edges by
hinge-like means. The hinge-like means 40,41 engage the recessed portions 58 such
that, when a handle 62 is manually operated, the drum like member 56, via a gearing
arrangement 55, facilitates movement of the display sign panels 34.
[0005] As will be appreciated, the device of AU 640211 is quite difficult to manufacture
due to its vast number of components, is cumbersome to operate due to the necessity
to turn handle 62 - which may typically be positioned some two metres above ground
level, and is prone to breakage - due to its complex design and incorporation of many
moving parts.
[0006] The present invention seeks to provide a display device which overcomes the disadvantages
of the prior art.
[0007] The present invention also seeks to provide a display device which enables the alternative
positioning of a display means between, a viewing position, and one or more storage
position(s), such that, different displays can be provided at different predetermined
times throughout the day, etc.
[0008] United States Patent Specification No. US-A-4 110.925 discloses a display device
having rollers (26 and 27), about which a chain is driven by a motor. A carrier is
driven between the rollers (26 and 27), the carrier being positioned by additional
rollers (28) such that the display is viewed through window 17, being backlit by lights
(23).
[0009] German Patent Specification No. DE-A-3 901 053 discloses a display roller (9 and
11) driven by a motor M (15) such that one of a plurality of displays contained on
a carrier (8) may be provided into position for viewing through a window (3), being
backlit by lights (12).
[0010] In one broad form, the present invention provides a display device, including:
at least two rotatable roller members located in substantially parallel spaced apart
relationship;
a carrier means, embodied as a belt, band or the like, and, formed of a lightweight
polycarbonate or like plastics material being tightly supported by
and rotatable about said rollers and/or onto at least two of said roller members,
in a spool-like manner, and. adapted to receive at least one display means thereon,
each of said carrier means and said display means being constructed at least partially
of substantially flexible and translucent material;
each display means embodied as translite(s) (as herein defined) and/or slat(s) being
sized and shaped to fit between a pair of adjacent rollers such that one or more discrete
rest position(s) is automatically identified after said display device is rotated,
whereby, in said rest position(s), one of said display means is centrally positioned
between a respective pair of rollers; and,
illumination means, provided behind at least a portion of said carrier means, to illuminate
a viewing portion of said carrier means and said display means thereon.
[0011] In a preferred form said translite(s) is/are attached to said carrier by a substantially
transparent/translucent adhesive material.
[0012] In an alternatively preferred form of the invention said translite(s) is/are attached
to said carrier by a covering sheet provided over substantially the entirety of said
carrier, such that each translite is positioned between said carrier and said covering
sheet.
[0013] In an alternatively preferred form said translite(s) is/are attached to said carrier
by a hook and loop fastening system, such as Velcro.
[0014] Preferably, each said slat(s) is attached to said carrier by slat carrier means.
[0015] Preferably, each said slat carrier means has a lip thereon to support an edge of
a respective slat.
[0016] Preferably, each slat may optionally be provided with at least one window portion

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0024] As shown in Fig. 1, a display device 30 comprises a pair of rotatable roller members
31 and 32 located in parallel spaced apart relationship. A carrier means 33 is mounted
between the roller members 31 and 32, in a belt like manner. It may either rotate
in the direction of arrow 34, the direction of arrow 35, or, in both directions 34
and 35, one at a time. Rotation of the carrier may be effected either manually, or
by drive means, which is not shown in the drawings. The drive means may either drive
one or both of the roller members 31 and 32 to thereby selectively move the carrier
means 33. The carrier means 33 is adapted to receive at least one display means 36
in a removable manner thereon. Preferably, the embodiment depicted in the drawing
will be provided with at least two display means 36 thereon, one on the "front" of
the display device 30, and one on the rear of the display device 30. By operation
of the drive means, the display means 36 may be selectively moved between a viewing
position and a storage position. That is, the viewing position will be at the front
of the display device, and the storage position will be at the rear of the display
device.
[0025] Lights or other illumination means 37 are provided between the roller members 31
and 32 to illuminate the display means 36 when in the viewing position. This is achieved
by constructing the carrier means 33 and the display means 36 at least partly of transparent
and/or translucent material or the like, such that the light can shine therethrough.
[0026] As shown in Fig. 1(b), the display device 30 may be provided in a housing 39 - the
housing 39 being intended to be provided in an overhead position behind a serving
counter in a restaurant, bar, shop or the like. It will be appreciated that , by installing
the device 30 in such a housing 39, the device 30 faces a person in front of the counter.
[0027] As hereinbefore mentioned, the display means is removably attached to the carrier
means by any known means, for example, by a substantially transparent or translucent
adhesive material such as used for window stickers, etc, or by other known means which
permits easy placement and removal such a velcro, sticky tapes, or the like. The display
device may either be used to alternatively, intermittently or continuously, display
two or more display means 36, by intermittently or continuously rotating the rollers
31 or 32, or, by an electric/electronic drive means, to move one of at least two display
means to a viewing position, one at a time. This may, for example, be useful for displaying
at least two menus, one at a time, in a fast food restaurant, whereby one menu is
to be displayed during breakfast, and another menu is to be displayed during lunch
or dinner at predetermined times. For example, the menus could be changed at 10.00
am when it is desired to cease displaying the breakfast menu and thereafter display
the lunch menu. The display device may be operated such that the drive means causes
the breakfast menu to be moved from the front to the rear of the display device such
that the lunch menu is thereafter displayed.
[0028] Suitable control circuitry may be provided to automatically affect this operation,
or, the drive means may be manual, or be operated by a switch, electrical component/circuitry
or the like.
[0029] One of the features that makes the display device of the present invention different
from the display devices of the prior art, is the material of which the display device
belt 38 is fabricated. This belt, or carrier means, is, in accordance with the present
invention, constructed of a substantially flexible and translucent material. That
is, the carrier means or belt is preferably constructed of a plastics or other polycarbonate
material such as "LEXAN". This allows the belt to stretch between the pair of rollers
31 and 32 and rotate thereabout. The use of such a material allows easy hand movement
of the display device, unlike the prior art device, such as shown in Australian Patent
640211, which requires a cumbersome operation of a handle. The use of such a polycarbonate
material such as LEXAN also has translucent characteristics allowing the illumination
means 37 to shine therethrough. An extremely useful characteristic feature of using
such a tightly provided but lightweight belt about the rollers, is that "self-alignment"
is achieved, as will be described in more detail hereinafter.
[0030] As mentioned hereinbefore, either a single "translite" 36 or a plurality of slat
like members may be positioned in the outline shown by reference numeral 36. The term
"translite" is a term known to persons skilled in the art and is used to refer to
a substrate or transparency which may have an image printed thereon or formed otherwise
thereon by digital imaging. The image may be any combination of words, logos, pictures,
etc. As such, when the term "translite" is used throughout this specification, it
should be considered to be defined to encompass such meaning. It will be appreciated
that a further "translite" or set of slat like members would also be provided on the
back surface of the belt 38. Obviously, when in use as a display sign, there is no
sign attached to the curve portions or end portions of the overall device, i.e. the
portion about the rollers 31 and 32. Consequently, a unique effect of the invention
results. That is, due to natural balancing effects, automatic alignment of the display
portions occurs to 'rest positions', such that a display is either provided on the
front or back surface, but does not tend to stop halfway between the front and back
and about the rollers 31 or 32. This is facilitated by the combination of lightweight
materials for the belt and a smooth rolling action of the rollers 31 and 32.
[0031] As mentioned hereinbefore, a single transparency can be supplied on to each of the
front and back surfaces of the belt 38, such as within the dotted lines shown by reference
numeral 36 in Fig. 1. A variety of means can be utilised for attaching a single transparency,
such as glues, velcros, tapes, etc.
[0032] Alternatively, a plurality of slat holders may be supplied on to the belt, such that
slats may be easily inserted therein.
[0033] Such a slat arrangement in shown in Fig 3, Fig. 3(a) illustrating a front view thereof,
and Fig. 3(b) illustrating an elevational view thereof. Details of a particular slat
is illustrated in front view and elevational view in Figs. 3(c) and 3(d). The slats
slide into the slat carriers, as will be understood, behind a lip provided along each
edge of the carriers.
[0034] In Fig. 4 is shown an indicia display capsule or indicia module, useful for use with
the slat arrangement of Figs. 3. Front and elevational views are shown in Figs. 4(a)
and 4(b). By this unique design of the indicia display capsule, indicia may be easily
inserted into the capsule as shown in Fig. 4c, and then, due to the provision of unique
protruding portions 40, the capsule may be easily inserted into position and held
therein between pairs of slats. Consequential sliding in or out of the slats over
the capsule does not result in movement of the capsule. Such a module may be useful
in display devices other than that shown in the drawings.
[0035] It will be appreciated by persons skilled in the art that numerous variations and
modifications will become apparent.
[0036] For example, as it will be appreciated by persons skilled in the art, depending on
the number of display message required, variations to the device, with differing numbers
of rollers, can be made. Examples of such variations are shown in Fig. 2. Fig 2 shows
the use of a plurality of single size rollers in Figs. 2(a), 2(b) and 2(c), the use
of smaller diameter rollers - in Figs. 2(d) and 2(e) - which enable a 'longer' viewing
area on the front of the display device, and, the use of rollers wherein the carrier
may roll onto the rollers - in Fig. 2(f). Such an embodiment of Fig. 2(f) may be particularly
useful where space constraints are defined.
