Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention involves a slat winding type shutter (hereinafter referred to as a "shutter") and a first screen that is fed out, a second screen that is unfolded in front of the first screen, and a second screen that is rolled out in front of the first screen.
This invention relates to a display device that is attached to a screen and attached to the front surface of a shutter for displaying paintings, etc. on a second screen.

(Prior Art) Conventionally, methods of using a shutter as a display medium include drawing pictures directly on the shutter surface, and recently, placing a printed banner on the front of the shutter and connecting the lower part of the banner with the bottom edge of the shutter. A device that is connected and displayed in conjunction with the opening and closing of the shutter has been developed.

(Problem to be solved by the invention) However, in this conventional banner that is linked to the opening and closing of the shutter, only the lower part of the banner is fixed to the shutter, and the middle part of the banner is not fixed at all, so it flaps around in the wind. It was not suitable for outdoor use and its range of use was limited. In addition, since it requires a wide cloth, the cost becomes high when printing costs are included, and there is also the problem that it cannot be replaced frequently and does not taste as fresh. Another problem was that the lower end of the banner must be connected to the lower end of the shutter, so the banner was limited to regular shapes.

In addition, in shutters used outdoors, large irregularities are formed on the slats to increase the section modulus and provide strength in order to resist wind pressure and other external forces. For this reason, when the shutter was unwound and unfolded, unevenness appeared on the entire surface of the shutter, and when a screen was directly applied to this and a printing sheet was unfolded, the unevenness of the shutter extended to the printing sheet, making it unsightly. . or,
When increasing the thickness of the screen in order to solve this problem, there was a problem in that it was difficult to wind up the screen, attach it to the shutter, etc.

(Means for Solving the Problems) The present invention has been made to solve the problems of the conventional art, and is a material that can be used outdoors without flapping in the wind, and is also a material for printing paintings, etc. to be displayed. aims to provide a display device that can be used with anything such as paper, thin film, cloth, etc., and can be made in any size and shape, allowing for a wide variety of exhibitions. The first screen, which has an adhesive force such as a hook-and-loop fastener, is wound into a roll and attached in contact with the feeding part of the shutter, and the second screen is wound into a roll and attached to the first screen. Attaches to the front of the
A painting or the like is applied to the front surface of the second screen, and when the shutter is opened and closed, the first screen is attached to the shutter surface and linked, and when the second screen is attached to the first screen and unfolded, the second screen is painted. (2) A display device that is attached to the front of the shutter and is characterized by displaying items such as A second screen is attached so as to be in contact with the feeding part, and a second screen having magnetic adhesion on the back side is attached to the front of the first screen in a rolled-up state, and a picture or the like is applied to the front of the second screen. The front surface of the shutter is characterized in that the first screen is interlocked with the opening and closing of the shutter, and when the second screen is attached to the shutter from above the first screen and unfolded, paintings, etc. on the second screen are displayed in front. Display device attached to.

(3) A screen with a strip-like suction surface on the back is wound up into a roll and attached so that it is in contact with the feeding part of the shutter, and a painting or the like is applied to the front of the screen, so that when the shutter is opened or closed, the screen is attached to the front of the shutter. A display device attached to the front surface of a shutter is characterized in that a picture or the like on the front surface of the screen is developed by attaching it to the front surface of the shutter.

(Function) In this invention, two screens, a first screen and a second screen, are arranged in front of the shutter. The first screen immediately in front of the shutter is attached so as to be in contact with the shutter, and is linked to the opening and closing of the shutter. In the case where the first screen has adhesive force on both sides, as the shutter is unrolled, the first screen is also unrolled, and the screen is completely attracted to the shutter by the adhesive force on the back side of the screen and unfolded. Even if this shutter is used outdoors and the slats have large irregularities, this first screen is applied to almost eliminate the irregularities and form a smooth plane.

A second screen is attached to the front of the first screen. This second screen is opened and closed in conjunction with or not in conjunction with the shutter. In either case, the unrolled screen is completely attracted to the first screen surface by the adhesive force of the first screen and unfolds. If the first screen does not have adhesive force, attach a magnet to the second screen and use its own adhesive force (magnetic force) to attach it to the shutter through the first screen. The first screen adheres to the uneven surface of the front surface of the shutter to form a smooth flat surface, so if the second screen is strong, it can maintain a smooth flat surface even if it is extremely thin. Displays such as paintings are displayed by being attached to the front of this second screen. Therefore, the printed sheet can be of any size, shape, and material.

(Example) The present invention will be explained in detail below using examples.

Embodiment 1 The embodiments shown in FIGS. 1 to 7 are equipped with magnetic force, adhesive force, hook-and-loop fastener, etc. as adhesion force on both sides of the first screen, and in any case, the adhesive force on the back side is used to shutter the screen. The second screen is attached by the adhesive force of the surface. This first screen is wound up into a roll on a winding drum, and is pivotally supported in contact with the feeding portion of the shutter, and the lower end of the screen is connected to the lower end of the shutter. Further, the bearing that pivotally supports the winding drum has an elongated hole shape so that the distance from the contact portion of the shutter can be adjusted depending on the outer diameter of the roll on which the screen is wound. This first screen should preferably be something that is stiff, such as a thin galvanized iron plate, a stainless steel plate, a fiber woven fabric, or a foamed polyethylene sheet.

Also, the second screen may be linked or not linked to the shutter, and if it is linked, the winding drum is supported by a bearing with an elongated hole in the same way as the first screen, and the roll of the second screen is transferred to the feeding section of the first screen. Pivotally supported in contact. In the case of non-interlocking, the screen is supported separately from the first screen, and the winding drum shaft is driven electrically or manually to open and close the screen. When the front surface of the first screen is a hook-and-loop fastener, a hook-and-loop fastener is also attached to the back surface of the second screen. This second screen is made of the same material as the first screen and has a printed sheet applied to its front surface.

Figure 2 shows that the second screen is linked to the shutter.
Figure 4 shows the case of non-interlocking, in which 1 is the first screen, 2 is the second screen, 3 is the winding drum, 4 is the drum shaft, 5 is the bearing, 6 is the bearing bracket, and 7 is the long 8 is a shutter, 9 is a plurality of strip-like magnetic thin plates arranged in parallel, 10 is a drive motor for a non-interlocking second screen, and 11 is a printing sheet.

Further, 12 is a band-shaped adhesive layer as an adhesive force other than magnetic force, and 13 is a same-surface fastener, and a large number of small pieces of surface fastener are regularly arranged on the shutter side and the back side of the second screen. In this example, the first
Since both sides of the screen have adhesive strength, the second screen does not require any adhesive force unless the front surface of the first screen is made of hook-and-loop fastener, and therefore it is a hassle to replace the second screen. Moreover, it can be manufactured at low cost.

Embodiment 2 In the embodiment shown in FIGS. 8 to 11, no adhesive force is applied to the first screen, but a magnet is attached to the back surface of the second screen to provide magnetic adhesive force. This first screen is linked with the shutter, but the second screen may be linked or not linked with the shutter. Since the first screen has no adhesive force to the shutter, a magnet is attached to the second screen so that it passes through the first screen and attaches to the shutter, and the first screen is attached to the shutter together. In addition, the material of both the first screen and the second screen is not limited, and may be thin galvanized iron plate,
Stainless steel plates, woven fiber cloth, foamed polyethylene sheets, etc. are used.

Figure 8 shows that the second screen is linked to the shutter.
FIG. 9 shows the case of non-interlocking, in which 20 is the first screen, 21 is the second screen, and 22 is a strip-shaped magnetic thin plate attached to the back surface of the second screen.

Furthermore, a second screen formed entirely of a magnetic sheet may be attached to a small shutter or the like.

Embodiment 3 In the embodiment shown in FIG. 12, the lower end of the screen is connected to the lower end of the shutter, and a printed sheet such as a painting is directly applied to the screen that is brought into contact with and interlocks with the shutter, and the screen is placed on the front of the shutter as the shutter opens and closes. The printed sheet is displayed by unfolding it.

This screen is made of thin galvanized iron plates, stainless steel plates, woven fiber cloth, foamed polyethylene sheets, etc. The figure shows a foamed polyethylene sheet, on the back of which a strip-shaped magnet thin plate is arranged as a strip-shaped attraction surface at the same pitch as the shutter slat pitch.

Stainless steel foil (50μ to 100μ thick) is bonded to the front surface of this foamed polyethylene sheet to increase its strength. Also, since this sheet is flexible, it makes good contact with the shutter and can be rolled up and lowered smoothly.

In the figure, 30 is a screen, 31 is a polyethylene sheet, 32 is a stainless steel foil, 33 is a strip magnetic thin plate, 34 is a screen roll, 35 is a shutter, 36 is a slat, 37 is a drum, 3
8 is a drum shaft, 39 is a bearing, 40 is a bearing bracket, 41 is an elongated hole, and 42 is a printing sheet.

In this embodiment, the screen roll 34 comes into contact with the shutter 35 and is rotated as the shutter 35 opens and closes. While the screen roll 34 is rotating, the roll outer diameter constantly changes, but the distance between the shutter 35 and the drum shaft 38 is adjusted by the elongated hole 41.
In this case, the first screen is omitted, but a thick polyethylene sheet (3 mm thick) is used to prevent the unevenness of the shutter from appearing on the printing sheet. This has the advantage that the first screen does not cost as much as the first screen and requires less space for installation.

(Effects of the Invention) As described above, according to the present invention, screens covered with display printing sheets of various shapes and materials can be firmly attached to the front of the shutter, and can be displayed without flapping in the wind. be able to. or,
By covering the uneven surface of the shutter with the first screen, it is possible to create a clean display with good flatness without causing unevenness on the printed sheet, etc. Moreover, since only the printing sheet can be replaced, a very inexpensive display can be produced.
