IMAGE DEMO SYSTEM

DESCRIPTION

The present utility model relates to image display systems, and can be used, in particular, to display various advertising and / or information images, for example, large-format images.

In the state of the art, dynamic advertising informational installations are widely used, containing rotating around their own axis prisms with components printed on their faces that make up a changing advertising image. Such a technical solution is described, for example, in Russian patent RU 2269826. However, the displayed images of such installations are limited by the number of faces of the prism, since it is essentially impossible to provide high-quality images if the prisms of the advertising installation contain more than four faces. In addition, in the prior art there is a known method of displaying images in one window of the demonstration device, when the images are interconnected into a tape. The tape is wound on one shaft and fixed on the other. When rewinding tapes with images from one shaft to another, images are displayed in turn in a window. However, this method has inherent disadvantages. Firstly, such a design is usually one-sided. The only way to make it double-sided is to install two identical back-to-back mechanisms. Secondly, replacing images is an expensive and time-consuming process. To replace one image, you need to disconnect the images, and then very accurately combine with the new one. To do this, use special locks. Moreover, the implementation of such a replacement in the winter on the street is especially problematic. Thirdly, images are shown only sequentially one after another, as they are located on the tape, in the forward or reverse direction. At the same time, the extreme images in the roll are shown less often than the average ones, and the sequence of demonstration is always the same. Fourth, the number of images, as a rule, is limited to 5-6 pieces, since winding one upon the other, they form a very heavy roll of large diameter. It is also very difficult to wind a long ribbon evenly.

Moreover, significant problems arise when changing images during their demonstration, carried out horizontally. When the cartridge shafts are arranged vertically, the material sags around the middle when rewinding from one shaft to another, which makes it impossible to ensure that the image carrier is properly wound onto the shaft. To eliminate this drawback, it is necessary to apply strong tension to the image carrier, which ultimately greatly complicates the system and makes it expensive.

The purpose of this utility model is to eliminate the disadvantages inherent in the prior art. In addition, the purpose of this utility model is to create an image demonstration system that is easy to use and when replacing images. An additional goal of this utility model is the creation of such a system of demonstrating images, which provides any order of demonstration of images, as well as allows you to demonstrate a large number of images. Moreover, the purpose of this utility model is to create a system for displaying images, providing both one-sided and multi-sided demonstration of images.

Figure 10 is a schematic sectional view of a removable cartridge with an image carrier that can be used in the system according to the present utility model.

As shown in FIG. 1, the image demonstration system has a housing 1, which can be made of any suitable materials, for example, metal or plastic, and which can be arranged to be placed both on a horizontal base (eg, floor), so and on vertical or inclined walls. In this case, the housing can be made with the possibility of its rotation around its longitudinal axis. The housing 1 may have doors on its sides for access to its interior. The housing 1 shown in FIG. 1 has two substantially parallel demonstration sides 2, one of which is visible, and the second is not. However, the demonstration sides can be not only parallel, but also can be located at any given angle to each other. The demonstration side 2 has an opening 3 for displaying images, the area of which is part of the demonstration side 2. In this case, when the housing is rotated, the demonstration sides 2 change their position. Demonstration opening 3 may have a substantially transparent protective agent, usually in the form of glass or plexiglass, to protect the displayed image. In the absence of a transparent protective means to prevent the carrier of the image from oscillating in the wind, strings (not shown) can be stretched from one or both sides to limit its movement. At least one removable cartridge 4 with an image carrier is installed inside the housing 1, including a drum 5, one end of which is configured to bring the drum into rotation, for example, by fixing its ends on rigidly mounted shafts 5 '; moreover, on the drum 5 of the cassette 4, one end is attached to the image carrier 6, which is wound on the drum 5. Moreover, it should be noted that a removable cartridge with an image carrier is not an object of this utility model, and therefore, in the system according to this utility model any known design of a cassette with a drum for winding the image carrier (see, for example, Fig. 10) is used, which is installed and fixed inside the system case by any known method. The image carrier 6 may be any material known and used for this purpose, such as paper, fabric, synthetic or natural, non-woven material, etc. To demonstrate it, each medium 6 with an image, such as, for example, an advertising image that can be performed on both sides of the medium, is unwound from the drum. However, one cassette is installed only when the system is used in the "poster" mode.

If the system is used to demonstrate several images, then the number of 4 cassettes with media increases accordingly. Cassettes 4 with image carriers are arranged essentially vertically, that is, have a substantially vertical longitudinal axis, and are located on the side of the opening 3 for displaying images. Preferably, the number of such cassettes with image carriers is not limited to one or two cassettes and can be any number of cassettes depending on the volume available for their placement. Alternatively, the cassettes 4 with the image carriers are placed in the nests made for their placement, having a shape corresponding to the shape of the shaft 5 'of the cassette 4 with the image carriers. If the shaft 5 'of the cartridge 4 with the image carrier is made cylindrical with a cross section different from the circle, then the socket also has a non-circular complementary cross-section. If the shaft 5 'of the cassette 4 with the image carrier has a polygonal cross section, for example, hexagonal, then the socket for the cassette has a corresponding hexagonal shape.

Each cartridge 4 has a drum 5 coaxial with the central axis, on which the image carrier 6 is fixed at one end and onto which it is wound. After winding onto the drum 5, at the free end of the image carrier 6, a traction bar 7 is fixed, which can be any structure that makes the edge of the image carrier 6 rigid and fixed in the bar 7. In one embodiment, such a traction bar 7 can be made in the form of two elongated essentially flat plates placed on both sides of the image carrier 6 and connected by means of fastening (not shown), for example, screws or screws with nuts. The traction bar 7 is intended for its capture and implementation of the unwinding of the image carrier for display in the opening 3 to display images.

To rewind the image carrier 6 back to the cartridge drum, the system has means for winding the image carrier (not shown) the number of which corresponds to the number of cartridges 4. Each of the means for winding the image carrier is designed to rotate the drum 5 when winding the carrier 6 of the image onto the cartridge drum 5 and can be any known device of this purpose, both mechanical in the form of a spring or a system of counterweights, and electromechanical in the form of a drive electric motor. At the same time, the means for winding the image carrier can be placed both on the respective cassettes 4 with the image carriers, for example, at their ends, and on the corresponding sides of the system housing 1. In the case of installing the means for winding the image carrier on the housing 1 of the system, the system further comprises means for transmitting rotation from each means for winding to the corresponding adapted to bring the end face of the drum cartridge. Such transmission media are not the subject of this utility model and mechanisms of any type known in the art can be used as such media, for example, both mechanical and electromechanical couplings.

For the implementation of the demonstration of images by unwinding media 6 images from the reels 5 of the cassettes 4 with the storage media, the system has at least one device for controlling the demonstration of images, which consists of a node 8 for placement of the traction bars 7 of the cassettes 4 with the media 6 images. In the example shown in FIG. 1 and 2, the assembly 8 is a plate 9 with substantially L-shaped elements 10 fixed thereon, the number of which corresponds to the number of cartridges on display. Moreover, each element 10 is made with a groove extending in a vertical plane through which the image carrier 6 is passed. At the end of the horizontal section of the L-shaped element 10 in contact with the traction bar 7 of the respective image carrier 6, a protrusion 11 is formed that enters the recess of the traction bar 7, having a shape complementary to the shape of the protrusion 11, so that the traction bar 7 is held by the L-shaped element of the assembly placing traction bars made in the form of a plate 9. The plate 9 can be driven by any known engine, for example, an electric motor, or by electromagnets.

To carry out the demonstration of the image in such a way as to prevent sagging of the image carrier 6, the system has a device for capturing and maintaining the image carrier 6 in a taut position. Such a device includes a plurality of clips 12 for gripping the image carrier 6 (see Fig. 5-7). The clamps 12 are mounted on a closed clamp carrier 13 or, alternatively, being connected in series, one with the other or via additional links, form such a closed clamp carrier 13, tensioned on the drive pulleys 14. The clamps 12 are arranged to move a substantially rigid guide 15 The movement can be carried out, for example, by a roller element 16 or any element known from the prior art. The clamp 12 itself can be made, for example, in the form of two openable plates having locking elements directed to each other (pointed pins, notched lips, etc.), which are closed in the normal state. Moreover, to improve the capture of the image carrier by the clamps, their ends can have a toothed profile and / or material with high frictional properties can be applied to their ends. To bring the clamps 12 from the open state to the open state when capturing the movable image carrier 6, the capturing device has a means intended for this that is not the subject of this utility model, and any device known from the prior art, such as as a wringer 17.

The device for capturing and maintaining the carrier 6 of the image in tension also have a grip 18, designed to capture the traction bar 7 of the specified media 6 image. The gripper 18 has a shape corresponding to the shape of the traction bar 7 for its engagement and subsequent movement along the guide 15.

The rigid guide 15 for the clamps 12 and the gripper 18 is located in the area between the opposite lateral sides of the opening 3 for displaying images and is essentially perpendicular to the axes of the cartridges 4.

To carry out the movement of the traction bar 7 of the specified image carrier 6, that is, before the image is displayed, it must be set to its original position, which is the position when the traction bar placement unit (plate 9) installs the traction bar 7 of the specified set using the traction bar assembly installation means the image carrier 6 in the plane of the carrier 13 of the clamps 12 and the gripper 18 in such a way that when the closed carrier 13 moves, the gripper 18 engages the end of the traction bar 7 and starts its movement.

At the same time, a motor (not shown) is used to drive the drive pulleys 14, and a controller (not shown) is used to control the operation of the engine and move the mounting means of the traction bar assembly, a description of which is not given since any known programmable device can be used in its quality.

If necessary, any type of lighting fixtures (not shown) may be placed in the system case to provide suitable image illumination.

To demonstrate a large number of images with a large number of removable cartridges 4 with image carriers installed essentially in rows arranged one after another, rods 19 are used to arrange the supply of traction bars 7 to the gripper 8, which are fixed at one end to the top plate 9 and the other end - on the corresponding bottom plate (not shown). The image carriers 6 bend around the rods 19 while passing the pull rods 7 to the L-shaped elements 10. Moreover, due to the fact that the axis of the rods are essentially parallel to the axes of the cassettes 4 with the image carriers, the image carriers 6 get an orientation parallel to the plane of the opening 3 of the demonstration side 2.

For additional tension of the image carrier 6 in the fully expanded state, the guide 15 of the clamp and gripping carriers can be made of two complementary elements 20 and 21 (see Figs. 8 and 9), which are made with the possibility of displacement relative to each other.

Optionally, a substantially transparent screen, for example of plexiglass, can be mounted in front of and / or behind the stretched image carrier 6 to protect the image carrier or to provide more uniform illumination thereof.

The system operates as follows.

The image to be demonstrated on the medium 6 is placed in a removable cartridge 4 with the image carrier by fixing it on the drum 5 and winding it onto the drum 5. After that, the pull bar 7 is fixed on the free end of the image carrier, and the finished removable cartridge 4 is delivered to its installation location in the system image demonstrations. The cassette 4 with the image carrier 6 is inserted into the slot for its placement in such a way that only the drum 5 is rotated to rewind or unwind the image carrier 6. At the same time, the traction bar 7 is installed in the node 8 for placing the traction bars so that it engages on the corresponding complementary protrusion 11 of the L-shaped element 10. The system operator selects the number of the cassette 4 with the image carrier for demonstration and sets it to the controller. Depending on the number of the selected cartridge, the controller generates commands received by the means for setting the traction bars 7 of the image carriers 6, which biases the plate 9 in the direction transverse to the direction of the guide 15 along which the clamps 12 move, until the specified traction bar is set to its original position under capture 18. Upon receipt of a command to start the demonstration, the engine drives the drive pulleys 14, which, in turn, drive the closed carrier 13 of the clamps 12 and of the capture 18. Z pulling the grip 18 engages the bar 7 and, moving along the guide 15, it pulls along the opening 3 for the demonstration image carrier 6 therein. The clip 12, following the capture 18, during its translational movement is opened by means for bringing it from the clamped to the expanded state, and then closes again, capturing the image carrier 6. Each clip 12 performs similar actions during its movement, thus ensuring the capture of the image carrier 6 along its entire length at certain intervals.

If the cartridges are installed on both sides of the housing 1, the system has two mirrored halves located on the sides of the housing 1, the grips 18 of which are rigidly connected to each other. In this case, one of the double grippers 18 captures the traction bar 7 when moving in one direction between the sides, and the second when moving the traction bar 7 in the opposite direction, ensuring the retention of two traction bars 7 at the same time. After one image has been shown, the connected captures 18 are moved in the opposite direction, and the image shown on the medium 6 is wound onto the drum 5 of the cartridge 4 by the means of winding the image carrier 4. At the same time, one image carrier 6 is pulled from the cartridge on the opposite side image carrier 6. If desired, the demonstration can be repeated many times. After the demonstration, the removable cartridge 4 with the image carrier is removed from the system and replaced with another removable cartridge 4 with another carrier 6 of the image to be demonstrated.

As shown, the image demonstration system according to the present utility model provides quick and easy operation, in which ready-made removable cartridges with image carriers are quickly and simply installed or replaced in the system and provide a demonstration of a large number of images.

Although the utility model is shown and described with reference to some variants of its implementation, it will be clear to those skilled in the art that various changes can be made to them in form and detail without departing from the spirit and scope of the utility model.
