[0001] The present invention relates to an information displayer with interchangeable boards.
[0002] More particularly, the invention relates to a device of the above kind that allows
to display different boards, particularly advertising boards in a selective manner.
[0003] It is well known to those who are experts in the art that more or less recently different
kinds of devices have been realized, said devices allowing to change the image displayed
towards the public.
[0004] A first device of this kind provides a number of horizontal triangular-shaped elements
that can rotate about their horizontal axis, so that, rotating the different faces
in synchronism, it is possible to change the message that is visible to the public
according to a predetermined timing.
[0005] Is is well evident that this kind of device is rather limiting from a functional
point of view: in fact, it allows the vision of only three different advertising messages,
and only according to a rigid sequence.
[0006] Furthermore, if it is desired to replace the advertising message, it is practically
necessary to replace all the device, such an operation involving high costs and remarkable
practical drawbacks.
[0007] A second kind of device to display different images to the public already available
on the market is the one comprising a sheet wound on two rolls and having a sequence
of images to be displayed printed on it.
[0008] Winding and unwinding the sheet on said rolls it will be possible to change the message
shown to the public.
[0009] In this case the number of available messages can also be high, although it is in
any case is limited by the sizes of the sheet.
[0010] However, the above device does not allow to propose the messages according to a casual
and selective sequence, since the choice is binded by the order of the messages printed
on the sheet.
[0011] Furthermore, it is very difficult, troublesome and expensive, or even impossible
or economically not convenient, to replace the sheet with another one having a different
group of advertising messages.
[0012] In GB-A-182 964 a picture displaying apparatus is disclosed, said apparatus comprising
removable picture roll drums or carriers and preferably means for rendering the picture
exhibiting mechanism inoperable unless it is in the correct operating position.
[0013] In US-A-1 700 435 an automatic advertising machine is described wherein a number
of advertisements are singly and consecutively brought into view.
[0014] In view of the above, the Applicant has studied and realized a displayer of multiple
information or images that allows to display the images according to a casual sequence,
i.e. according to any pre-established sequence.
[0015] Moreover, the solution according to the invention allows to realize a displayer wherein
the images are arranged over boards that are selectively displayed.
[0016] A further object of the present invention is that of realising an image displayer
wherein the information over the boards are included in two "loaders" that can be
easily and quickly replaced without the need to move or modify the structure of the
displayer.
[0017] It is therefore specific object of the present invention to provide an information
displayer with interchangeable boards comprising at least a container of n boards,
provided with means to selectively take out said n boards; means to grasp the board
to be displayed; and means to bring the board in a display position and to bring back
the same into the container.
[0018] According to a first preferred embodiment of the displayer according to the invention,
the displayer comprises two carrier elements, or "loaders", each for n boards, provided
substantially one above the other; means to grasp the board to be displayed from the
upper loader or from the lower loader; and means to bring the same panel in a display
position, and then to bring back the same into the upper or lower loader wherefrom
it has been taken out.
[0019] Particularly, each one of said loaders is provided with n supports, preferably made
up by cylindrical supports preloaded by harmonic steel spring, wherefrom the boards
are taken out to be displayed, or whereon are bring back after the display, and whereon
the boards remains wound when they are not used.
[0020] Preferably, according to the invention, said loaders are releasably coupled to the
displayer so that they can be replaced with other ones containing different boards.
[0021] Said loaders are preferably realized with a stepping motion, with a number of steps
corresponding to the number of boards provided.
[0022] The movement is preferably obtained by a stepping motor for each loader, controlled
by a pre-programmed microprocessor, that operates a toothed flange so as to transmit
the motion to the same loader.
[0023] Further, according to the invention, said means to grasp the board to be displayed
and to bring it in a display position, provided both for the upper loader and for
the lower loader, comprises movable elements arranged at 45° each other on a rotating
roll, projecting from the roll to grasp the board by means of a leverage system controlled
by an actuator device, preferably a solenoid.
[0024] In a second preferred embodiment of the displayer according to the invention, said
means to selectively take out said n boards comprises a first pin element, provided
externally on the container, slidable along a slot realized on the same container,
and couplable with a hole realized on the boards; a second pin element, provided at
the bottom of the container, and parallelly disposed with respect to the same container,
couplable with said hole realized on the boards, said container being movable along
a direction parallel to the axis of said pin elements.
[0025] Preferably, said container is realized with a stepping motion, with a number of steps
corresponding to the number of boards provided.
[0026] The motion is preferably obtained by a stepping motor, controlled by a pre-programmed
microprocessor, that operates a cam having n tracks.
[0027] Further, said first pin element is moved along said slot by an electric motor.
[0028] Said means to grasp the board to be displayed e to bring it in a display position
are preferably made up by movable elements, which are arranged on a rotatable roll
at 120° each other, and which can be projected from the roll to grasp the board, or
withdrawn within the same roll to release the board by an actuating device, preferably
a solenoid.
[0029] Said means to bring the board in a display position and to bring it back within the
housing cylinder can be provided, apart from the above mentioned roll rotatable in
both the directions, one or more magnetic strings to properly position the board.
[0030] Still according to the invention, said container is releasably coupled to the displayer
so that it can be replaced with another one containing different boards.
[0031] According to a third embodiment of the displayer according to the present application,
two set of boards are provided, disposed respectively according to an articulated
chain rotating around pulleys means, at least a motor being provided to move said
chains.
[0032] Preferably, it is provided only one motor that operates said two board chains, rotating
in both the directions, said motor being connected by a belt or other suitable means
with one of the pulley of each chain.
[0033] Further, according to the invention, each one of said boards can be made up of a
cylindrical container, having inside a hub over which the sheet rolls up, spring means
being provided so as to determine the automatic roll up of the sheet around the hub.
[0034] Again according to the invention, the selective display of the boards occurs bay
a rigid bar provided on the front portion of the displayer according to the invention,
said bar being moved by a motor and motion transmission means, preferably chain means
that rotates around sprocket means, and coupled with coupling means provided on the
outer edge of the board.
[0035] Again according to the invention, said container is provided with n housings for
n boards.
[0036] On each board it can be laterally provided a set of perforations matchable with said
movable elements, said perforations being spaced each other of a pitch corresponding
to the distance between said movable elements.
[0037] Furthermore, two metallic reinforcing strips, having perforations, and eventually
inner reinforcement metallic strips, can be provided on said boards.
[0038] Behind the board displayed a further reinforcement element can be provided.
[0039] The present invention will be now described in the following, in an illustrative
but not limitative way, according to its preferred embodiments, with particular reference
to the figures of the enclosed drawings, wherein:

figure 14 is a perspective view of a board for an displayer according to the invention;
and
figure 15 is a partial view of the board of figure 14.
[0040] Referring now to figures 1 to 6 of the enclosed drawings, it can be noted that the
information displayer according to the invention is an electromechanical device provided
with an automatic selective system that allows to display alternatively, from the
above or from the bottom and according to a desired sequence, a number n of images
printed on the boards.
[0041] The displayer 1 comprises two elements 2 or "loaders" bearing the boards, arranged
one at the top and one at the bottom, and having each one n cylinder 3 with boards
4, said loaders 2 having a rotating motion, as it will be more clear in the following.
[0042] Every single loader 2 is provided, as already said, with n housing cylinders 3, one
for every board 4 to be displayed. In the figures, every loader 2 provides eight cylinders
3.
[0043] Each one of the boards 4, see in particular figure 6, is provided with transverse
steel strips 5, 6, the outer ones being provided with perforations 7 spaced of a predetermined
pitch.
[0044] The arrangment to display the boards 4, both for the upper loader 2 and for the lower
loader 2, is made up, as it can be observed in figures 3 and 4, of a roll 8 provided
with eight sectors 9, preferably movable sectors, arranged at 45° each other, operated
by suitable levers 10 controlled by the solenoid 11.
[0045] The roll 8 can rotate in the directions of arrows A of figure 5.
[0046] It is further provided a plurality of magnetic belts 12 (see figure 2) that are useful
to obtain a proper display of the board 4.
[0047] The steel strips 5, 6 provided on each board 4 have the goal to reinforce the same
allowing to obtain an optimum display and to reinforce the edges that engage with
the movable sectors and over which said perforations 7 are realized to drag the board
4.
[0048] Obviously, in case the board 4 is realized with a material sufficiently resisting,
it would be not necessary to provide said strips 6, 7.
[0049] The motion of the cylinders 3 according the direction of the arrows B in figure 5
is obtained by a stepping motor 13 having a number of steps corresponding to the number
n of boards 4 provided.
[0050] To display the different boards 4 according to suitable and pre-established sequences,
the stepping motor 13 will be controlled by a microprocessor (not shown) with a suitable
software.
[0051] The operation of the displayer 1 according to the invention will be described in
the following with reference to a displayer wherein the different boards 4 are sequentially
displayed, but it is obvious that the same principles are valid in case of a casual
pre-established display of the boards.
[0052] The upper loader 2 is positioned so as to present the end edge of the board 4 rolled
up on the corresponding preloaded cylinder 3 along a perfect vertical direction, see
in particular figure 3, so that the movable sector roll 8, moved by the solenoid 11,
can be positioned within the corresponding perforation 7 on the edge of the same board
4. The same operation is valid for every other board 4.
[0053] Now, by means of a stepping motor 14, the roll 8 starts its rotation until it reaches
the complete display of the board 4, see clear arrows A, A' of figure 5.
[0054] To bring back the board 4 just displayed in the original position, wound again within
its cylinder 3, the roll 8 rotates in an opposite direction, according to the dark
arrows A, A', helped during this rotation by the springs 15 provided within the cylinder
8 and loaded during the preceding unrolling step for the display.
[0055] It is to be noted how, at the same time as the beginning of the return step of the
board 4 displayed, the movable sector 9 placed on the bottom roll 8 of the displayer
1 is already engaged with the end edge of the board prepared by the lower loader 2
according to the work sequence exposed above, being so possible to start a new and
immediate display of a new board 4, in this case from the bottom to the above, so
that which dead times usually necessary to change the board to be displayed are completely
eliminated.
[0056] In order to obtain the display of all the n boards 4, it is sufficient that the upper
and lower loaders 2, following rotation due to the stepping motor 14, prepare the
end edge of the next board 4 as described above and according to the alternation criteria
between the upper one and the lower one.
[0057] From the above, it is well evident how, programming the stepping motors 13 of the
loaders 2 by the already mentioned microprocessor, it will be possible to determine
the desired casual display sequence of the various boards 4.
[0058] Coming now to observe figures 7 to 11, it is shown a second embodiment of the displayer
according to the invention comprising a container 101 for n boards 102, and movable,
as it will be more specifically described in the following, along a direction perpendicular
with respect to the plane of the boards 102.
[0059] The container 101 is provided with n housings (not shown), one for each board 102.
[0060] The container 101 has a first pin 103 slidable according to arrows A within a slot
104, provided externally with respect to the same container 101, and a second pin
105 provided at the bottom of the container 101.
[0061] Each one of the boards 102 (see figure 8) is provided with transverse steel strips
106, 107, the outer two of which (106) presents perforations 108 spaced of a predetermined
pitch.
[0062] Always on the strips 106 there is provided a hole 109 for the insertion of the pins
103 and 105, as it will be evident in following. The arrangment to display the boards
102 is made up of a roll 110 provided with three movable sectors 111 arranged at 120°
each other and operated according to the direction of arrow B by solenoids 112 (see
figure 9).
[0063] Roll 110 rotates along directions indicated by arrow C.
[0064] It is provided a magnetic string 113 that allows to obtain an optimum display of
the board 102.
[0065] The strips 106 and 107 provided on the board 102 attend to reinforce the same allowing
at the same time to obtain its optimum display, and, moreover, to reinforce the edges
that engage with the movable sectors 111, and over which the perforations are realized.
[0066] Obviously, in case the material of the board is sufficiently resistant, it could
also be unuseful to provide said strips 106, 107..
[0067] The pin 103 is moved along the slot 104 by a motor (not shown).
[0068] The motion of the container 101 according to the direction of the arrow D is obtained
by a stepping motor (not shown) and a cam (not shown) having a number of profiles
corresponding to the number n of boards 102 provided.
[0069] To display the different boards 102 according to suitable and pre-established sequences,
the stepping motor will be controlled by a microprocessor with a suitable software.
[0070] The operation of the information displayer according to the invention is as follows,
and it is quite similar to the one of the displayer of figures 1-6.
[0071] It will be now described in the following the way how the different boards 102 are
sequentially displayed, but it obvious that the same principles are valid in case
a pre-established casual display of the boards 102 is wished.
[0072] The container 111 will be in a completely lifted position, so that the pin 103, see
dashed lines in figure 9, engages within the hole 109 of all the boards 102.
[0073] Advancing the pin 103 along the slot 104, until the position shown in full line in
figure 9 is reached, the board 102 is brought with its firts perforation 108 corresponding
with the first movable sector 111.
[0074] Said sector 111 is operated by the solenoid 112 and therefore engages the board 102.
[0075] Now, by the stepping motor and the cam contour (not shown), the container 101 descend
of a step so that the pin 103 disengage the hole 109 of the board 102 coupled to the
movable element 111, that will be free to be dragged by the roll 110, by the three
movable elements 111, until reaching its complete display.
[0076] To bring back the board 102 within the container 101, the roll 110 rotates in an
opposite direction with respect to the preceding one till bringing the board 102 with
the hole 109 in correpondance of the pin 103. The container 101 is now lifted of a
step, so that the pin 103 engages again the hole 109 of the board 102 formerly displayed
and, sliding again along the slot 104 towards the bottom, brings back the board 102
within the container.
[0077] To display the next board 102, the container 101 is slided of a step downward, so
that the pin 105 engages the hole 109 of the board formerly displayed.
[0078] Now, the pin 103, sliding upward along the slot 104. will bring the second board
102 in correspondance with the movable element 111 and the above described cycle can
be repeated.
[0079] It is well evident that in this case too, suitably programming the stepping motor
that controls the motion of the container 101 it will be possible to determine the
desired casual display sequence of the different boards 102.
[0080] Referring now to figures 12 to 15, the embodiment shown provides two chains 201 each
comprising twelve boards 202 connected by articulated joints to realize the chain
structure so that each chain rotates about two pair of pinions 203, 204, the first
ones (203) being idle and the second ones (204) being connected through the transmission
205 with a motor 206.
[0081] The chains 201 made up by single panels 202 are realized opposite and symmetrical
each other and, employing idle wheels that allow a single rotation direction, the
motion can be controlled by a single motor 206.
[0082] Hooking and releasing of the board to be displayed is realized by a plurality of
hooks 207 provided along a rigid bar 208, the ends of which are coupled to the links
of two chains 209 moved by a motor 210 (see figure 13).
[0083] Each single board 202, see figure 14 and 15, is included within a container or "magazine"
211 comprising a hub 212, rotating inside the container 211, and having the board
202 rolled up on it, by the action of a spiral spring 213.
[0084] Along the edge of each board opposite to the edge coupled with the container 211,
it is provided a number of openings 214 that couple with the hooks 207 of the rigid
bar 208.
[0085] The programming of the display sequence of the different boards is realized in a
way similar to the one already described with reference to the above mentioned embodiments.
[0086] In this case, by the motor 206, a board 202 from one of the two chains 201 is brought
in a display position, and said board 202 will be displayed by the translation of
the rigid bar 208, through the action of the system comprised of chains 209 and motor
210, said rigid bar 208 having grasped the board 202 involved by the coupling of the
hooks 207 with the openings 214.
[0087] While displaying the board 202 according to the pre-established sequence, the rigid
bar 208 determines the rolling up of the board 202 formerly displayed inside the corresponding
roll 211 by the returning action of the spring 213.
[0088] It should be pointed out that this kind of board, as well as the display mechanism,
can be used for the other embodiments too.
[0089] The present invention has been described with specific reference to its preferred
