Abstract
Description
- The present invention relates to an information displayer with interchangeable boards.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Winding and unwinding the sheet on said rolls it will be possible to change the message shown to the public.
- 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.
- 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.
- 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.
- 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.
- In US-A-1 700 435 an automatic advertising machine is described wherein a number of advertisements are singly and consecutively brought into view.
- 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.
- Moreover, the solution according to the invention allows to realize a displayer wherein the images are arranged over boards that are selectively displayed.
- 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.
- 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.
- 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.
- 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.
- 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.
- Said loaders are preferably realized with a stepping motion, with a number of steps corresponding to the number of boards provided.
- 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.
- 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.
- 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.
- Preferably, said container is realized with a stepping motion, with a number of steps corresponding to the number of boards provided.
- The motion is preferably obtained by a stepping motor, controlled by a pre-programmed microprocessor, that operates a cam having n tracks.
- Further, said first pin element is moved along said slot by an electric motor.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Again according to the invention, said container is provided with n housings for n boards.
- 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.
- Furthermore, two metallic reinforcing strips, having perforations, and eventually inner reinforcement metallic strips, can be provided on said boards.
- Behind the board displayed a further reinforcement element can be provided.
- 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 13 is a front view of the displayer of figure 12;
- 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.
- 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.
- The
displayer 1 comprises twoelements 2 or "loaders" bearing the boards, arranged one at the top and one at the bottom, and having each onen cylinder 3 withboards 4, saidloaders 2 having a rotating motion, as it will be more clear in the following. - Every
single loader 2 is provided, as already said, withn housing cylinders 3, one for everyboard 4 to be displayed. In the figures, everyloader 2 provides eightcylinders 3. - Each one of the
boards 4, see in particular figure 6, is provided withtransverse steel strips perforations 7 spaced of a predetermined pitch. - The arrangment to display the
boards 4, both for theupper loader 2 and for thelower loader 2, is made up, as it can be observed in figures 3 and 4, of aroll 8 provided with eightsectors 9, preferably movable sectors, arranged at 45° each other, operated bysuitable levers 10 controlled by thesolenoid 11. - The
roll 8 can rotate in the directions of arrows A of figure 5. - 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. - The
steel strips 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 saidperforations 7 are realized to drag theboard 4. - Obviously, in case the
board 4 is realized with a material sufficiently resisting, it would be not necessary to provide saidstrips - The motion of the
cylinders 3 according the direction of the arrows B in figure 5 is obtained by a steppingmotor 13 having a number of steps corresponding to the number n ofboards 4 provided. - To display the
different boards 4 according to suitable and pre-established sequences, the steppingmotor 13 will be controlled by a microprocessor (not shown) with a suitable software. - The operation of the
displayer 1 according to the invention will be described in the following with reference to a displayer wherein thedifferent 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. - The
upper loader 2 is positioned so as to present the end edge of theboard 4 rolled up on the correspondingpreloaded cylinder 3 along a perfect vertical direction, see in particular figure 3, so that themovable sector roll 8, moved by thesolenoid 11, can be positioned within the correspondingperforation 7 on the edge of thesame board 4. The same operation is valid for everyother board 4. - Now, by means of a stepping
motor 14, theroll 8 starts its rotation until it reaches the complete display of theboard 4, see clear arrows A, A' of figure 5. - To bring back the
board 4 just displayed in the original position, wound again within itscylinder 3, theroll 8 rotates in an opposite direction, according to the dark arrows A, A', helped during this rotation by thesprings 15 provided within thecylinder 8 and loaded during the preceding unrolling step for the display. - It is to be noted how, at the same time as the beginning of the return step of the
board 4 displayed, themovable sector 9 placed on thebottom roll 8 of thedisplayer 1 is already engaged with the end edge of the board prepared by thelower loader 2 according to the work sequence exposed above, being so possible to start a new and immediate display of anew 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. - In order to obtain the display of all the
n boards 4, it is sufficient that the upper andlower loaders 2, following rotation due to the steppingmotor 14, prepare the end edge of thenext board 4 as described above and according to the alternation criteria between the upper one and the lower one. - From the above, it is well evident how, programming the stepping
motors 13 of theloaders 2 by the already mentioned microprocessor, it will be possible to determine the desired casual display sequence of thevarious boards 4. - 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 forn boards 102, and movable, as it will be more specifically described in the following, along a direction perpendicular with respect to the plane of theboards 102. - The
container 101 is provided with n housings (not shown), one for eachboard 102. - The
container 101 has afirst pin 103 slidable according to arrows A within aslot 104, provided externally with respect to thesame container 101, and asecond pin 105 provided at the bottom of thecontainer 101. - 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. - Always on the
strips 106 there is provided ahole 109 for the insertion of thepins boards 102 is made up of aroll 110 provided with threemovable sectors 111 arranged at 120° each other and operated according to the direction of arrow B by solenoids 112 (see figure 9). -
Roll 110 rotates along directions indicated by arrow C. - It is provided a
magnetic string 113 that allows to obtain an optimum display of theboard 102. - The
strips 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 themovable sectors 111, and over which the perforations are realized. - Obviously, in case the material of the board is sufficiently resistant, it could also be unuseful to provide said
strips - The
pin 103 is moved along theslot 104 by a motor (not shown). - 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 ofboards 102 provided. - 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. - 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.
- 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 theboards 102 is wished. - The
container 111 will be in a completely lifted position, so that thepin 103, see dashed lines in figure 9, engages within thehole 109 of all theboards 102. - Advancing the
pin 103 along theslot 104, until the position shown in full line in figure 9 is reached, theboard 102 is brought with itsfirts perforation 108 corresponding with the firstmovable sector 111. -
Said sector 111 is operated by thesolenoid 112 and therefore engages theboard 102. - Now, by the stepping motor and the cam contour (not shown), the
container 101 descend of a step so that thepin 103 disengage thehole 109 of theboard 102 coupled to themovable element 111, that will be free to be dragged by theroll 110, by the threemovable elements 111, until reaching its complete display. - To bring back the
board 102 within thecontainer 101, theroll 110 rotates in an opposite direction with respect to the preceding one till bringing theboard 102 with thehole 109 in correpondance of thepin 103. Thecontainer 101 is now lifted of a step, so that thepin 103 engages again thehole 109 of theboard 102 formerly displayed and, sliding again along theslot 104 towards the bottom, brings back theboard 102 within the container. - To display the
next board 102, thecontainer 101 is slided of a step downward, so that thepin 105 engages thehole 109 of the board formerly displayed. - Now, the
pin 103, sliding upward along theslot 104. will bring thesecond board 102 in correspondance with themovable element 111 and the above described cycle can be repeated. - 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 thedifferent boards 102. - Referring now to figures 12 to 15, the embodiment shown provides two
chains 201 each comprising twelveboards 202 connected by articulated joints to realize the chain structure so that each chain rotates about two pair ofpinions transmission 205 with amotor 206. - The
chains 201 made up bysingle 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 asingle motor 206. - Hooking and releasing of the board to be displayed is realized by a plurality of
hooks 207 provided along arigid bar 208, the ends of which are coupled to the links of twochains 209 moved by a motor 210 (see figure 13). - Each
single board 202, see figure 14 and 15, is included within a container or "magazine" 211 comprising ahub 212, rotating inside thecontainer 211, and having theboard 202 rolled up on it, by the action of aspiral spring 213. - Along the edge of each board opposite to the edge coupled with the
container 211, it is provided a number ofopenings 214 that couple with thehooks 207 of therigid bar 208. - 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.
- In this case, by the
motor 206, aboard 202 from one of the twochains 201 is brought in a display position, and saidboard 202 will be displayed by the translation of therigid bar 208, through the action of the system comprised ofchains 209 andmotor 210, saidrigid bar 208 having grasped theboard 202 involved by the coupling of thehooks 207 with theopenings 214. - While displaying the
board 202 according to the pre-established sequence, therigid bar 208 determines the rolling up of theboard 202 formerly displayed inside thecorresponding roll 211 by the returning action of thespring 213. - It should be pointed out that this kind of board, as well as the display mechanism, can be used for the other embodiments too.
- The present invention has been described with specific reference to its preferred embodiments, but is is to be understood that changes and/or modification can be introduced by those skilled in the art without departing from the scope of the invention as defined in the enclosed claims.
