Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention unwinds together with a slat roll-up type shutter (hereinafter referred to as "shutter") to apply a screen having characters and pictures drawn on the front surface of the shutter. The present invention relates to a display device that is developed into a state and is wound separately from the shutter as the shutter is wound.

[Conventional technology]

Conventionally, when a large display is used in the city, it is limited to rooftop signboards, etc., and it is the front of the shutter that displays a large area near the ground, but this shutter covers a part of the wall of the building. Since it is composed, it was disliked to display characters and pictorial patterns on it, and most of them remained plain.

Further, a screen juxtaposed shutter in which screens are juxtaposed on the front surface of the shutter with a certain interval is known from Japanese Utility Model Laid-Open No. 58-151293.

Separately from this, a smoke blocking screen is wound in a roll shape and erected on the extension part of the shutter, male and female surface fasteners are attached at the positions where the shutter and the screen are opposed to each other, and they are opposed by a pressing roller while extending the shutter. Japanese Patent Application Laid-Open No. 53-133453 discloses a smoke blocking device having a structure in which the surface fasteners are pressed together to attach the screen to the shutter and deploy the screen together with the shutter.

[Problems to be Solved by the Invention]

With the conventional method of displaying characters and pictorial patterns on the front of the shutter with paint etc., it is difficult to express precisely because the shutter slats are uneven, and again for time-limited advertisements etc. There was a problem that repainting was difficult in terms of time and cost due to adjustment of the base.

Further, the screen of the shutter of Japanese Utility Model Laid-Open No. 58-151293 is developed in a tensioned state by a screen winding spring or a driving device. Therefore, it easily shakes due to the wind, generates noise and vibration due to fluttering, and the screen surface becomes wavy due to wind, and wrinkle distortion occurs due to tension, reducing the value as a screen surface for advertising and projection. There was a drawback that caused it. Even if the both edges of the screen were guided along the guide rails to solve this problem, it was not enough to stop the fluttering, wrinkling and movement of the center of the screen. Also, it is difficult to put a poster on the screen when it is developed and to draw letters and pictures with ink, paint and brush because the screen is easy to move.

Further, in the smoke blocking device disclosed in Japanese Utility Model Laid-Open No. 53-133453, a hook-and-loop fastener must be attached to the slat surface of the shutter, and since this hook-and-loop fastener projects considerably from the slat surface, it is damaged when opening and closing the shutter. However, it was easy to come off and lacked durability. There is no problem with a flame-proof screen such as a smoke-preventing screen that is developed only when flames and flames are inspected, but the shutter at the entrance and exit used daily lacks practicality.

The object of the present invention is to solve these conventional problems with a simple structure and at a low cost, and the developed screen becomes rigid so that it is easy to paste posters, draw letters with ink, and draw pictures. Therefore, it is another object of the present invention to provide a practical shutter-interlocking display device in which the screen can be easily replaced.

[Means for Solving the Problems]

The gist of the present invention is to rotatably install a screen wound in a roll shape in a state of being in contact with a feeding portion of a shutter of a slat winding type by a pressing device, and erratably installing the roll-shaped screen, Moreover, a magnet or an adhesive is entirely attached to the shutter facing surface of the screen, and the screen is attached to the front of the shutter by the magnetic force or the adhesive force of the shutter when the shutter is extended, and is developed. Located on the display device.

[Action]

In the present invention, since the screen wound in the form of a roll is touched by the shutter, the roll is rotated by frictional resistance when the shutter is extended and the screen is extended, and moreover, the adhesive force of the magnet or the adhesive applied to the screen. The screen adheres to the shutter, descends with the shutter, and when the shutter is completely closed, the screen is developed so as to cover the front of the shutter.

By designing various advertisements, photographs, etc. on the surface of this screen, it is possible to have a large and smooth plane and to display within a range where the line of sight is not unreasonable.

Since the screen of the present invention adheres to the entire shutter surface or a portion including the central portion, the screen does not flutter or shake due to wind or the like. Moreover, the shutter attached to the screen functions as a reinforcing material for the lining of the screen, and in the expanded state, the screen and the shutter are integrated to become an advertising signboard, rigidity is generated on the screen, and a poster or the like can be easily attached, Also, it becomes possible to easily draw letters, pictures, etc. on the screen surface with ink. Also, since the screen is installed detachably, it can be easily replaced for each roll when the time limit has expired or has become old.

〔Example〕

 Embodiments of the present invention will be described below with reference to the drawings.

In describing each embodiment, the same reference numerals are used for the same components.

The shutter-linked display device (1) of the present embodiment is
The screen (2), the shaft (3) and the pressing device (4) are the main components. In addition, (5) is the shutter body,
(6) is a slat, and (7) is a winding device, and the slat (6) is connected to form a shutter main body (5), and the shutter main body is wound or rewound by the winding device (7). 5)
Open and close in the vertical direction.

The screen (2) has flexibility, and is composed of a magnet plate (8) which is not attached to the screens but is attached only to the shutter body (5), and an advertising paper (9) attached to the surface thereof.

The screen (2) is the shaft end (10) of the shaft (3),
(10) is projected and wound in a roll shape, and the shaft end portions (10) and (10) are detachably inserted into the long groove (11) of the bracket (12) so as to be installed in the extending portion of the shutter. .

Further, the pressing device (4) has a bracket (12) having a long groove (11), a shoe (13) which advances and retracts in the longitudinal direction of the long groove (11), and biases the shoe (13) in the forward and backward directions. It is formed with a spring (14). The shaft ends (10) and (10) of the shaft (3) are axially supported by the long groove (11) through the bearing (15), and the shoe (13) always moves the bearing (15) in one direction. The roll-shaped screen (2) is arranged so as to be pressed against the shutter body (5) by pressing.
