Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a shutter device equipped with an opening of a building, a show window, or the like, and more specifically, for decoration photographs, paintings, characters, patterns, and other advertisements. A flexible screen that is formed such as is provided so that it can be wound up integrally with a shutter curtain in which a large number of slats are connected, and the shutter curtain that is under blockage is used as a space for advertising or a wall surface for decoration. The present invention relates to a shutter device equipped with a screen.

[Conventional technology]

As a technique for providing the screen so that it can be wound up integrally with the shutter curtain, for example, as shown in FIGS. 13 and 14, a slat 41 with a groove and a plurality of slats 42 are provided.
While sequentially connecting the two to form the shutter curtain 43,
A screen 44 on which a decorative pattern or the like is formed is located on the front side of the shutter curtain 43, and while the screen 44 is being pushed into the concave groove h of the slat 41 with concave groove, a presser bar 45 is inserted into the concave groove h. There is one that is inserted (for example, Japanese Utility Model Laid-Open No. 62-42693).

[Problems to be solved by the invention]

By the way, the pitch dimension of the slats 42, 42 when the shutter curtain 44 is wound into an arc shape is the same as the slats 42, 42 when the shutter curtain 44 is closed.
Needless to say, it is larger than the pitch dimension of.

However, conventionally, the press rod 45 is fitted into the slat 41 with the concave groove so that the screen 44 is stretched, and therefore the screen 44 can be wound in order to wind the shutter curtain 43. In order to absorb the deviation between the shutter curtain 43 and the shutter curtain 43, it is necessary to give the screen 44 considerable elasticity, which limits the selection of the material of the screen 44 and increases the cost. In addition, there is a problem that the pressing rod 45 may come off or the screen 44 may be damaged when an excessive force is applied to the screen 44.

Further, when the screen 44 is pressed by the pressing rod 45, the screen 44 becomes wrinkled or distorted, and a part of the screen 44 is covered by the pressing rod 45.

The present invention has been made in view of the above situation,
It is an object of the present invention to provide a shutter device equipped with a screen, which is suitable for use in which the above-mentioned inconveniences are alleviated by an extremely rational improvement.

[Means for solving problems]

In order to achieve the above object, the present invention is to wind a flexible screen having pictures, paintings, characters, patterns, etc., as described at the beginning, together with a shutter curtain having a large number of slats connected thereto. In a shutter device provided with a screen that is detachable, a screen extension mechanism for energizing and extending the screen in a state that allows relative movement of the screen and the shutter curtain in the winding direction of the screen is provided. The mechanism is composed of a cord-like body linked to the screen and a tensioning device that applies tension to the screen, while restraining the bias of the tensioning device in the tensioned direction when the shutter curtain lands, and does not restrain when the shutter curtain does not land. It is characterized in that a lock mechanism that can be switched is provided.

[Action]

According to the above characteristic configuration, by providing the screen stretching mechanism, the screen is stretched on the shutter curtain without being deformed or wrinkled and with good appearance.

Then, since the screen stretching mechanism absorbs the deviation between the screen and the shutter curtain due to the difference in pitch between the slats when the shutter curtain is fully closed and when the shutter curtain is fully opened, the shutter curtain is wound at the time of winding. No excessive force is applied to the screen.

Moreover, when the shutter curtain is landed, that is, when the shutter curtain is in the fully closed state, the looseness of the string-like body for stretching the screen is restrained, so that the tensioning device cannot be biased in the tensioned direction. Therefore, even if a strong wind blows between the screen and the shutter curtain and a strong wind pressure is applied to the back side of the screen, the screen does not flutter or easily swell.

Further, since the screen 10 can be freely moved in the screen winding direction along the string-shaped body 12 which is zigzag in the tension state, the shutter curtain 5
The deviation between the screen 10 and the shutter curtain 5 due to the difference in pitch between the slats 3 and 3 at the time of fully closing and fully opening can be absorbed, and it is possible to prevent the screen 10 from being subjected to an excessive force in the winding direction. .

Further, since the spacers 18 are provided on the back surfaces on both sides of the slat 3 in the longitudinal direction, the screen 10 is not pinched and damaged by the wound slat 3, 3.

By the way, the tensioning force applied to the cord-like body 12 by the tensioning tool 13 of the screen stretching mechanism 11 is weaker when the shutter curtain is fully opened than when the shutter curtain is fully opened. The shutter curtain 5 and the screen are
When a strong wind blows between the screen 10 and a strong pressure is applied to the back side of the screen 10, the tensioning device 13 is relaxed and the string-like body 12 is loosened, so that the screen is
There is concern that 10 may flutter or swell, causing inconvenience in terms of decorativeness and advertising effects.

In order to eliminate such an inconvenience, a lock which is switched when the shutter curtain 5 is landed, that is, when the shutter curtain 5 is fully closed, restrains the biasing of the tensioning device 13 in the tensioned direction, and does not restrain it when not landing. A mechanism 14 is provided to extend the screen 10 with a cord-like body 12.
The lock mechanism 14 is configured as follows.

That is, as shown in FIGS. 4 to 6, an opening 20 is formed in the horizontal seat plate portion 4a of the lower seat plate 4, and an L-shaped arm 22 having a cylindrical bearing 21 at the bent portion is provided. , The cylindrical bearing 21

On the other hand, the stopper member 25 is fixed to the vertical portion 12a of the string-like body 12 in the vicinity of the rotating body 19 by means such as caulking or screwing, and the stopper member 25 is detachable. Fork the stopper 26 into the arm
22 is connected to the vertical plate portion 22b, and further, the engagement of the stopper 26 with respect to the member to be stopped 25 is released, and the curtain fully closed detecting member 23 is projected from the opening 20 (see FIG. 5). A biasing tool 24 is provided between the arm 22 and the lower seat plate 4.

According to the above configuration, when the shutter curtain 5 is fully closed at the time of landing of the shutter curtain 5, the curtain full-close detection member 23, which is urged downward from the opening 20 of the lower seat plate 4, is protruded. Relatively receiving a pressing operation force by the bottom wall 29 of the building opening, the arm 22 swings in conjunction with this, and a stopper 26 connected to the arm 22 engages with the member to be stopped 25. In this way, the tensioning device 13
The bias is switched so that the bias of the strain in the tensioned direction is restrained (see FIG. 6).

Thus, since the string-shaped body 12 cannot be flexed, it is possible to prevent the screen 10 from fluttering or easily swelling even if a strong wind pressure is applied to the back side of the screen 10. is there.

In the above embodiment, when the shutter curtain 5 is fully closed (the stopper 26 is engaged with the member to be stopped 25), the stopper 26 and the member to be stopped 25 are closed.
Is configured so that a slight gap is formed between the cord and the cord so as not to apply an abnormal tension to the string-like body 12 due to an assembly error or the like. However, the tensioning tool 13 can be biased in the tensioned direction, but it is extremely small, and it goes without saying that such a configuration also falls within the scope of the present invention.

Further, in the embodiment, the cord 12 is formed in a zigzag shape and is inserted into the locking bodies 16 and 17. However, as shown in FIG. 7, the end of the cord 12 is located at the lower end side of the screen 10. It may be configured to be directly connected to, and in this case, it is important that the tension direction of the screen 10 is directed outward.

Alternatively, as shown in FIG. 8, a mechanism 27 for pulling and urging the lower end side of the screen 10 may be separately added.

Next, referring to FIGS. 9 and 10, the locking mechanism 14 of the first alternative embodiment is shown.

Is used as a reaction point, and the rod-shaped curtain fully-closed detection member 31 that is moved up and down in conjunction with the lower seat plate 4 is moved up and down.
Is inserted into the cylinder shaft 30 that is continuous with the curtain full-close detection member 31, and the cylinder 32 with the pin f is vertically slidably fitted to the curtain full-closed detection member 31, and the bias absorption spring is provided between the cylinder 32 and the seat 33. 34 is provided and the pin f is engaged with the elongated hole e of the arm 28. Therefore, when the shutter curtain 5 is fully closed when the shutter curtain 5 is landed, the curtain fully closed detection is performed. When the member 31 is driven up and the arm 28 swings in conjunction with this, the string-shaped body 12 is clamped and fixed by the fixed side member 35 and the string locking piece d.
Thus, the biasing of the tensioning tool 13 in the tensioned direction is restrained, and when not landing, it is switched so as not to restrain it.

FIG. 11 and FIG. 12 show the locking mechanism 14 of the second alternative embodiment. This is different from the locking mechanism 14 of the first alternative embodiment in the following points in terms of configuration.

That is, the drum in which the string-shaped body 12 is wound up and biased freely
A friction member 38, which is wound around and connected to the drum 37, releasably and frictionally fixes the winding string 12 to the drum 37 by applying a braking friction force, is pivotally attached to the lower seat plate 4, and the friction member is also provided. The elongated hole g formed in 38 is linked to the pin f, and in the first alternative embodiment, the cord 12 is clamped and fixed to restrain the bias of the tensioning tool 13 in the tensioned direction. On the other hand, the second embodiment is different in that the all-door cord-like body 12 is frictionally fixed to restrain the bias of the tensioning tool 13 in the tensioned direction.

As described above, according to the shutter device with the screen according to the present invention, by providing the screen expanding mechanism for urging and expanding the screen while allowing the relative movement of the screen and the shutter curtain, the shutter curtain is provided. A screen that is wound up with
The entire surface of the screen can be spread nicely without being deformed or wrinkled.

Then, since the screen stretching mechanism absorbs the deviation between the screen and the shutter curtain due to the difference in pitch between the slats when the shutter curtain is fully closed and when the shutter curtain is fully opened, the shutter curtain is wound at the time of winding. Not only is it possible to avoid the situation such as screen damage without applying excessive force to the screen, it becomes difficult to be constrained by the material selection of the screen, which in turn reduces the manufacturing cost of the screen. You can go down.

Moreover, by effectively utilizing the closing motion of the shutter curtain, when the shutter curtain is landed, the biasing of the tensioning device in the tensioned direction is not possible in the fully closed state, and the shutter curtain is closed when the shutter curtain is closed. A lock mechanism is provided to prevent the string-like body from slackening and to prevent it from being restrained when it is not landing, so a strong wind blows between the screen and the shutter curtain, and a strong wind pressure is applied to the back side of the screen. Even when the screen is fluttered, it is possible to prevent the screen from fluttering or swelling, and it is possible to achieve the spreading of the screen having a high decorative property and a high advertising effect.
