Description

MACHINE TO DISPLAY ADVERTISING

BACKGROUND OF THE INVENTION

The invention relates to a machine for displaying advertising, and in particular to a machine for displaying advertising designed for grouping with other machines for displaying advertising. The new design allows adjacent machines to be very close to each other, in order to minimize the spaces between adjacent advertising material. In addition, this invention relates to a simplified design of the machine, whose robustness of structure is especially suitable for use in sporting events in which the machine can receive some impact, and resulting easy access to the interior of the machine, both to change the advertising material to make adjustments and repairs.

Advertising machines are now known where a laminar body is wrapped around a screen-like roller. The advertising material is printed or otherwise fixed to the laminar body, moving it through a display window towards a rolling roller. Advertising messages are advanced from the roller to stand behind the window. To change the message, the sheet body is moved through the window until the next message is placed behind the window, at which time the sheet body is stopped. The mechanism of rotation of the laminar body is electronic, and is usually activated remotely. The possibility of changing the advertising message, in turn enables the commercialization of short periods of advertising time, thus satisfying the advertising demand of a larger segment of the advertising public. When the advertising message is established on a single sheet body, it will be inconsequential how much wider the machine is than the sheet body. However, in machines that are intended to be grouped together to use a series of laminar bodies in the exhibition of a single advertising message, it will matter how much wider the machine is than the laminar body. The reader will find puzzling and unsightly the vision of an opening in what should appear as a single message. Moreover, a large space could very well distract, thus losing the impact of the message. The former is important especially when contemplating a series of machines grouped on television. It is known from experience that when the television camera is focused on an advertisement grouped on a typical sports field, the maximum acceptable gap for the viewer is approximately 3/8 of an inch.

The rollers of the known technique are usually moved by uncomfortable drive belts and drive pulleys, which take up enough space. These transmission mechanisms are usually complex and make the machines large and bulky. The transmission mechanisms extend beyond the rollers, requiring complex interlocking designs to join the edges of adjacent laminar bodies when using grouped machines. In addition, state-of-the-art machines are difficult to maintain and have a unique configuration, so their usefulness is limited.

While the machines for displaying reference advertising have allowed remote advertising to change and grouping machines to display unique advertising messages, it would be interesting to be able to refine such machines to display advertising. Such better ones would be especially helpful if with This could enhance the usefulness of machines for displaying advertising, simplifying their structure.

SUMMARY OF THE INVENTION

Thus, an object of the present invention is to present an improved display machine.

Another object of the present invention is to present a machine for displaying advertising that can be arranged in proximity to an adjoining machine, so that the advertising laminar bodies are very close together, forming a single advertising message without presenting puzzling gaps.

Another object of the present invention is to present a machine for displaying advertising in which the laminar body occupies the entire width of the machine, thus minimizing the spaces between adjacent laminar bodies in a group of machines.

Another object of the present invention is to present a machine for displaying advertising with a laminar body mounted on a roller, the rollers being dragged by a simple transmission mechanism.

Another object of the present invention is to present a machine for displaying advertising that facilitates access to the interior of the machine, both to change the laminar body and to proceed with its repair and maintenance.

Another object of the present invention is to present a machine for displaying advertising specially designed for use in sporting events, provided with a structural element in the back of the exposed laminar body, which absorbs the impact against the window and therefore the laminar body.

A further object of the present invention is to present a machine for displaying very simplified advertising in which a laminar body is mounted on the outside of a cylindrical roller, with a drive motor that rotates the cylindrical roller, so that the bodies advance laminar mounted inside the cylindrical roller, the cylinder occupying the entire width of the machine and the laminar body also the entire width of the machine.

Another object of the present invention is to present a machine for displaying advertising whose ends provide steps for the wiring of the motors to the cylindrical rollers, thus eliminating the spaces between the ends of the cylinders and the ends of the machine.

A further object of the present invention is to present a machine for displaying advertising that allows the bending of an exhibition window, so that advertising can be arranged in curves, such as the corners of a hockey rink.

Another object of the present invention is to present a machine for displaying advertising that can be placed on a playing field, and protects the display mechanisms and the spectator audience.

Briefly, and in accordance with the present invention, a machine is planned to display advertising that can be used individually, or in conjunction with a group of machines, to display advertising messages. The messages are arranged in a laminar body, which is initially wound on a first cylindrical control roller. When a message is placed behind the display window, the laminar body is stopped. The message is changed by moving the laminar body between the rollers to the next message.

The drive motors of the laminar body between the cylindrical rollers are housed therein, thus enabling the occupation by the cylindrical rollers of the total width of the machine between its ends, and also allowing the laminar body to extend to the ends of the machine . Thus, when the machines are grouped, they are located contiguously, leaving the laminar bodies very close, allowing an appearance of continuity.

In a preferred embodiment, the ends of the machine are provided with grooves that communicate with the inside of the cylindrical rollers, to allow the wiring to be introduced, in effect, into the cylindrical rollers, without these having to be separated from The ends of the machine. The unusual wiring arrangement minimizes the gaps between adjacent machines, specifically the width of both machine edges. In addition, each machine has a structural element that extends between the ends of the machine and communicates with the grooves, so that the cylindrical roller cables can be introduced into the structural element, which houses the electronic components that, in part, they control the engines. The structural element is also it places behind the exposed part of the laminar body, absorbing the impact that could occur against the window and the laminar body in a sporting event. The machine also has easy access to the interior, from its front and back, in order to change the laminar body and proceed to maintenance. In addition, the machine will support a protection wall of the spectator audience, as is the case in hockey matches. In another embodiment, the grouped machines can be configured to form a curved vine, providing the necessary means for the window to assume the desired radius of curvature.

The objects, features and advantages of the invention will be expressly described in part and will also be partly detached, from the detailed description that is made following the invention, based partially on the drawings that are an integral part thereof.

DESCRIPTION DET & T. TADΑ rre T. & PTCΛT.TZACION PREFERENTE

Figure 1 shows a machine for displaying advertising, generally designated with the number 10, developed in accordance with the principles of the present invention. The machine 10 carries a seat plate 12, a front window based on a transparent plastic sheet 14, a back cover 16 and an upper plate 18, all joined together in the manner described in detail below, to form a structure as a drawer 20. The drawer 20 houses tension cylindrical rollers 22, 24, control cylindrical rollers 26, 28 and a central drawer 30. In the closure of the machine 10, end plates 32, 34 also participate, of which only one is shown in figure 1.

Figure 2 shows the seat plate 12 from the left end of the machine of figure 1. The seat plate is made of a very resistant material, such as steel, with a typical thickness of about 0.125 inches. The seat plate 12 only has simple curves and, in the case of metal-based manufacturing, can be manufactured through simple cutting and bending operations. The bottom 36 of the seat plate is horizontal, bending to form the front vertical surface 38, as well as a substantially vertical rear surface 40. The rear surface 40 is offset by its upper end 42 towards the front surface 38.

A molded piece of rubber 44 in D is provided, arranged horizontally on the upper end 42 and, as will be said later, acting as an adjustment surface for the lower end of the rear cover 16. The front surface 38 is bent towards back by its upper end. A square 46 in L is fixed to the bottom 36, arranged parallel and separately from the front surface 38. The vertical part 48 of the square 46 and the vertical front surface 38, define a groove 50 that receives the lower end of the plastic sheet 14 .

Figures 4 and 5 show the back cover. The cover 16 is made of a flat sheet of medium strength material, such as steel, and is usually about 0.125 inches thick. A pair of brackets 52 close to the lower end 53 of the cover 16 are fixed. As will be said, the brackets 52 secure the cover 16 to the upper end 42 of the vertical rear surface 40 of the seat plate 12. Two holes 54 are provided. at the upper end 56 of the cover 16, in which ratchets of closure 58 to secure the cover to the top plate 18. The cover 16 has the same width as the machine and, as will be seen, allows full access to the interior of the drawer 20, to install advertising laminar bodies and maintain the machine 10.

Figure 7 shows the top plate 18 from the left end of the machine 10 shown in Figure 1. The top plate has the same width as the seat plate 12. The top plate 18 is divided into a hinged front part 60 to the rear part 62. The hinge 64 allows the front part 60 to swing upwards in relation to the rear part 62. The front part has an anterior descending path surface 66 that turns on itself. A square 68 is provided in L, with a descending part 70 that runs along the width of the roof and is separated from the front surface 66. The descending part 70 and the front surface 66, define a groove 72 that receives the upper end of the plastic sheet 14. The rear part 62 has a descending surface 74, offset to the front part 60 by its lower end 76. A rubber molded part 78, in D, is provided horizontally arranged on the rear surface of the lower end 76 of the upper cover 18 and which, as will be described later, serves as an adjustment surface for the upper end 56 of the rear cover 16. The rear cover is made of a medium-strength material, such as steel, and usually has a thickness of 0.125 inches.

Figure 3 shows an end plate 34, which appears at the right end of the machine 10 of Figure 1. The end plate at the left end of the machine 10 is a tracing of the plate 34, and symmetrical from top to bottom. As will be said, the thickness of the end plate is very important in the grouped application of the machine to display advertising. The end plates are made of a high strength material, such as steel, with a thickness of about 0.125 inches. The end plates have a series of fixing holes 80, 82, 84, 86, 88, 90 of the roller systems used to move the sheet bodies. Holes 92 are also provided to align and bolt adjacent machines together. The plates are also provided with grooves 94, 96 for the motor control cables to descend through the plates, and a through hole 98 to pass electrical cables from one machine to another without having an external wiring.

Figure 6 shows a central drawer 30, in horizontal arrangement between the end plates. The drawer 30 is in U and is made of a high strength material such as steel. The drawer can be manufactured by simple cutting and folding operations. The drawer 30 has a front flat vertical surface 100, and two horizontal surfaces 102, 104, which are finished off in rear wings 106, 108, respectively. The drawer 30 extends between the end plates. The rear surface of the fins 106, 108 is aligned with the front surface of the rear cover, serving as a structural support for the rear cover, so that it cannot sink inwards. A cylindrical support is attached to drawer 30 to accommodate an optical sensor.

Figures 8 and 9 show a cylindrical roller 26 identical to the cylindrical roller 28. The cylindrical roller 26 is sectioned (Figure 9), exposing the drive assembly 109 that fits entirely in it. The drive assembly 109 carries an electric motor 110 and a drive gear 111 mounted on the end of a drive shaft 112. The drive gear 111 rotates a three-wheel planetary reduction gear system 112, which includes reduction gears 113, 114 , 115, all, coaxially attached to an associated rubber transmission wheel 116, 117, 118, respectively. Figure 9 shows only a reduction gear 113 and its associated drive wheel 116, in order to simplify the description. However, the description also applies to the rest of reduction gears and transmission wheels.

The drive wheel 116 is mounted on a drive wheel cylinder 119, threaded at both ends. The cylinder 119 has bearings 120, 121 fixed inside the cylinder at both ends, and with internal diameters smaller than the internal diameter of the cylinder 119. The cylinder 119 of the transmission wheel is arranged on a spacer cylinder 122, rotating around the cylinder 122 on bearings 120, 121 working on the spacer cylinder. This spacer cylinder 122 is mounted on the axis 123, which extends through a front plate 124 until the head 125 of the axis 123 contacts the front plate. The axis 123 follows the spacer cylinder 122 and is threaded to the motor 110 by the threaded end 126. Washers 127, 128 are arranged surrounding the cylinder 199 of the transmission wheel, on both sides of the transmission wheel 116. The reduction gear 113 is arranged around the cylinder 199 of the transmission wheel, fixed to the washer 128 by roller pivots 130, 132. The adjusting bolts 134, 136 are threaded to the threaded ends of the cylinder 119 of the transmission wheel, respectively.

When the head of the shaft 125 is pressed, the front plate 124 is pressed against the spacer cylinder 122, which in turn is pressed against the motor 110. Thus, the tightening of the three axes locks the front plate firmly against the motor , as a three-legged bench. The adjusting nuts 134, 136, when pressed against their respective washers 127, 128, will compress the rubber drive wheel 116, thereby expanding outward. When the adjusting nuts are tightened, the reduction gear 113 will be compressed against the washer 128, rotating with the washer to which it is attached, and the transmission wheel. The pins 130, 132 are long enough so that as the adjusting nuts are tightened, the pins are forced against the wheel 116, helping to transmit the movement of the reduction gear 136 to the wheel 116.

The view of Figure 8 does not show the front plate 124, the axis 123 and the details of the assembly, in order to simplify the description of the planetary gear system. The rubber drive wheels are dilated by adjusting the nuts 125 until a forced fit between the wheels and the inside of the cylinder is achieved. The motor assembly 109 is pushed to the cylindrical roller 28. The wheels 116, 117, 118 serve both to center the cylinder around the motor assembly, and to drag its internal surface as a toothed crown. Thus, the cylinder 28 forms an integral part of the gear reduction. The gear ratios and the size of the transmission wheels are chosen to present the necessary gear reduction, and to satisfy the geometric limitations of the interior of the cylinder. Figure 10 shows a set of ball bearings, used at both ends of the tension cylindrical rollers 22, 24, and at the end not containing the motor in each of the drive cylindrical rollers 26, 28. However the drive rollers have diameters larger than the tension rollers, the ball bearing assembly 146 of the drive rollers will be larger in diameter. The ball bearing assembly 146 has a base ring 148 mounted by ball bearings 150 to rotate about an axial support 152. As will be said, the axial support is fixed to an end plate. The base ring 148 is fixed inside the cylinder by means of screws 154.

Turning to Figure 11, a single machine unit for displaying advertising is mounted as follows. The central drawer 30 is positioned to center between the seat plate 12 and the upper plate 18, being welded or otherwise secured to the end plates 32, 34. The end plates 32, 34 are also welded to the seat plate 12, being welded to the back 62 of the upper plate 19. The end plates 32, 34, seat plate 12, rear part of the upper plate 18, and central drawer 30 thus constitute an integral structure welded as a drawer, with sufficient strength and robustness. Without the plastic sheet 14 and the back cover 16, the entire interior of the structure can be accessed as a drawer 20. Next, both transmission motor assemblies 110 are fixed so that the transmission wheels make good contact with the inside of the drive cylindrical rollers 26, 28. Next, a drive motor assembly is introduced at one end of each cylinder 26, 28. A set of ball bearings 146 is introduced at the other end of each cylinder 26, 28, fixing it by screws 154. The drive rollers are secured to the end plates 32, 34 by fixing the motors 112 to the end plates, by means of screws 156 (Figure 9) that pass through the fixing holes 84, 86 in the end plates . The ball bearing assemblies 146 are fixed to the end plates 32, 34 by screws 156 (Figure 10) that pass through the fixing holes 82, 88 in the end plates. The tension cylindrical rollers 22, 24 are connected to the end plates by fixing a set of ball bearing assemblies 146 to each end of the cylinders by means of screws 154. The tension cylindrical rollers are fixed to the end plates by means of screws 156, which pass through the fixing holes 80, 90 of the end plates.

As can be seen in Figure 11, both slots 94, 96 communicate with the inside of one of the control cylindrical rollers 26, 28 and with the central drawer 30. Thus, housing the electronic controls in the central drawer 30 and using flat conductors with a thickness of 0.125 inches or less, the conductors can freely cross the central drawer to the transmission motors (not shown), passing them through the slots 94, 96 to the inside of the control cylindrical rollers. This structure allows the rollers to extend from end plate to end plate without leaving a space for wiring. The hole 98 allows the wiring to pass from machine to machine, when used together.

A laminar body 160, typically a roll of paper or plastic, bearer of advertising messages, is wrapped around the cylindrical control roller 26, to which it is fixed, passing over the cylinder of tension 22, and then down and around the tension cylinder 24, and finally wrapping the control cylindrical roller 28, to which it is fixed. Tension cylinders can be covered with a layer of soft rubber to absorb any irregularities in the laminar body. A window 14, typically a high strength polycarbonate sheet of transparent plastic, is inserted into the groove 50. This can have an injection molded plastic or rubber profile 162, which dampens the lower end of the sheet 14. Also, it can be placing a rubber glove 162, for example, on the vertical part 48 of the square 46, serving as a damping to the plastic sheet 14. The groove 72 on the upper plate can also be provided with an injection molded damping profile 162 and a rubber glove 164, on the square 68. The upper plate 18 is closed on the plastic sheet 14, and can be immobilized by a ratchet closure assembly (not shown) or other suitable closing mechanism.

The rear cover 16 is fixed to the seat plate, on which it is supported, by means of the arrangement of brackets 52 on the upper end 42 of the seat plate, abutting the rubber molded part 44 in D. The upper part 56 of the rear cover 16 is closed against the rubber molded part 78 in D, locking by means of the ratchet fasteners 58.

In addition to carrying the electronic components, the central drawer 30 is a main structural element of the machine. It is usually arranged with its wide flat anterior surface 166 about 0.25 inches behind the plastic sheet, to leave a passage through which the laminar body rises and falls. The flat surface 166 also serves as support for the plastic sheet, if the sheet is impacted or pressed, for example by a hockey player or his disc. The plastic sheet will give inwards a maximum of 0.25 inches, contacting the front surface 166 of the drawer 30, which will serve as support. When the external force on the plastic sheet is undone, it will return to its original situation, so that the laminar body can move freely.

A series of advertisements are placed on the laminar body, the motor being activated either in the upper cylindrical roller 26 or the lower cylindrical roller 28, to move the laminar body up or down, until the desired advertisement is reached. The announcement may be centered vertically by means of an optical sensor (not shown), arranged in the mounting hole 110, on the front surface of the drawer 30. If an optical sensor is used, a black dot will be placed in the corresponding place on the part posterior of the laminar body. The sensor will be aware of the black spot, slowing the advance of the laminar body. Normally, the laminar body is controlled remotely from a personal computer. Ad data is stored on the personal computer that can control which ad appears and for how long. The possibility of marketing advertising time in small temporary segments increases the possibilities of advertising the advertising public.

When changing the announcements in the machine, the corresponding announcements of the laminar body are cut, sticking the new ones. The front face 166 of the drawer 30 serves as a valid surface for pasting new announcements. Figure 12 shows a group of two machines 10. The central end plates 32 and 34 are bolted through the alignment and bolting of the holes 92. Since the end plates have a thickness of only 0.125 inches each ,, both Extreme plates constitute a maximum space of 0.25 inches between the adjacent laminar bodies, which extend completely across the width of each machine. Thus, a single advertising message covering two machines or more will be pleasant for the eyes and, in particular, for the viewer.

Machine 10 can be adapted for specific sporting events. For example, Figure 13 is a top view of a machine whose plastic sheet 14 is straight in one half of the machine, from the left end, bending from the center to the right end. This is possible by bending the groove in the cover and seat plates, and folding the plastic to fit. The tension cylindrical roller 22 is in line with the straight part of the plastic sheet 14, and separated therefrom at the right end. The machine shown in Figure 14 is bent from the left continuously to the right end. The tension cylindrical roller 22 of Figure 14 is in line with the center of the plastic sheet 14, and is also separated from the sheet 14 at the left and right ends. As will be clear, a curve like that of a hockey rink is achieved by selecting suitable units of curvature, aligning them with each other. To constitute a curve, the left end of the machine of Figure 13 is paired with a straight machine and the right end is paired with another machine curved, as shown in Figure 14. The curve is finished using a machine half straight / half hunched, with the straight part on the right end.

The machine 10 of Figure 15 is mounted on an infrastructure 170, suitable for hockey. A bottom wall 172 of high density polyethylene is mounted on the front of the infrastructure 170. Also, an acrylic protector 174 is mounted on the machine.

Numerous modifications could be made to the invention, which fit within the spirit and scope of the invention. For example, the rollers could be secured to the end plates through a quick-release tongue and groove. In addition, since the machine is itself resistant and tight, it could be used for many indoor and outdoor uses. Due to their compactness, robustness and the possibility of maintaining them, accessing from their front or rear face, it would be easy to stack the machines to form an almost unlimited size. The machine can be manufactured based on other materials, such as reinforced plastic. Also, the window could be further secured through lateral vertical supports, in addition to the upper and lower grooves.
