Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an electric bay window shutter installed in a bay window of a building such as a house.

[Problems to be solved by the prior art and the invention] Conventionally, this type of electric bay window shutter has basically the same structure as the shutter for entrances and exits provided at openings such as entrances and exits of buildings. Therefore,
Inside the shutter case installed on the upper side of the bay window,
In addition to the winding wheel that winds up the shutter curtain, a drive mechanism equipped with an electric motor to drive the winding wheel must be installed at the same time, making the shutter case inevitably large. In cases where the opening space is narrow, it has become impossible to install due to the limited installation space, or the bay window lighting space has been sacrificed for installation, which has become a problem.

[Means for Solving the Problem] In view of the above-mentioned circumstances, the present invention was devised for the purpose of providing an electric bay window shutter that can eliminate these drawbacks. The upper end of the shutter curtain moves up and down using the guide rail as a guide to open and close the bay window.
The seat plate at the lower end of the shutter curtain is connected to the winding wheel, which is installed on the ceiling of the bay window and is constantly stored in the winding side via a coil bullet, and the upper end of the actuating wire passing through the guide rail. An electric drive mechanism is provided on the lower surface of the bay window floorboard, and the lower end side of the actuation wire is connected to the lower end of the actuation wire to wind up and unwind the actuation wire. The present invention is characterized in that a brake mechanism is provided which operates in conjunction with the stoppage of the mechanism to lock the shutter curtain upward when the lift is stopped.

According to the present invention, with this configuration, the shutter case provided above the bay window can be made extremely compact, with only the winding wheel side for winding the shutter curtain being housed inside.

[Example] Next, an example of the present invention will be described based on the drawings. In the drawing, 1 is a bay window in which the present invention is implemented, and the bay window 1 is composed of a ceiling board 2, a roof board 3, a floor board 4, etc., which are all the same as before. , left and right and upper and lower bay window frames 5, 6, 7, and 8 are attached to the front of the bay window 1. In this embodiment, the left and right bay window frames 5 and 6 and the vertical frame 10 provided on the pillar 9 on the building side
A sleeve plate 11 is attached between the sleeve plate 11 in a fitted manner. Also, upper bay window frame 7 and lower bay window frame 8
Guide rails 7a and 8a are respectively formed in the guide rails 7a and 8a, and sliding glass doors 12 and 12 are fitted therein so as to be slidable in the left and right directions, thereby allowing the bay window 1 to be opened and closed freely. It's summery.

Reference numeral 13 denotes a bay window shutter arranged to be located outside the glass doors 12, 12, and a shutter curtain 1 constituting the bay window shutter 13.
The shutter curtain 4 is designed to move up and down while being guided by guide rails 15 integrally formed with the left and right bay window frames 5 and 6, respectively. It is connected to a winding wheel 16 arranged above the winding wheel 7. The winding wheel 16 has its left and right ends rotatably mounted on a shaft 18 which is fixedly supported on a bracket 17a of a shutter case 17 which is installed between the upper window frame 7 and the roof board 3. In addition, the winding wheel 16
is constantly biased toward the winding side of the shutter curtain 14 by the stored force of the coil bullet 19 wound around the shaft 18.

On the other hand, reference numeral 20 denotes a drive motor with a brake mechanism fixed to the bottom surface of the floor board 4, which constitutes the drive mechanism of the present invention. It is interlocked and connected to a sprocket 22 provided in the. A support shaft 22a of the sprocket 22 extends in the left-right direction, and a take-up pulley 23 is integrally attached to both ends of the support shaft 22a. Further, upper end portions of a pair of actuation wires 25 are connected to the seat plate 24 at the lowest end of the shutter curtain 14 at both left and right end positions fitted into the guide rail 15. The lower end side of the actuating wire 25 passes through the guide rail 15, passes through a guide roller 25a provided on the bottom surface of the lower frame 6, and is wound around a take-up pulley 23 assembled on the lower surface of the floor plate. There is. Then, by operating a lower push button switch (not shown) provided on the indoor side to drive the drive motor 20, the operating wire 25 is activated.
is wound up on a take-up pulley 23, whereby the shutter curtain 14 is unwound from the take-up wheel against the coil bomb 19 and descends to close the bay window 1. When the seat plate 24 descends to the closed position where it comes into contact with the drain plate 8a provided on the lower frame 8, a limit switch (not shown) switches to stop energizing the drive motor 20 and brake the drive motor 20. The mechanism is activated to lock the automatic winding of the shutter curtain 14 by the stored force of the coil bomb 19, and to hold the shutter curtain 14 in the closed position.

In the embodiment of the present invention configured as described above, in order to close the bay window shutter 13,
When the lower push button switch is operated to drive the drive motor 20, the take-up pulley 2
3 rotates to wind up the actuating wire 26. As a result, the shutter curtain 14 is drawn out from the shutter case 17 against the coil bomb 19 and closes the bay window 1. When the shutter curtain 14 is lowered to its lowest position, the drive motor 20 is stopped by switching a limit switch (not shown), and at the same time the brake mechanism is activated, thereby locking the shutter curtain 14 in the closed position. Become. On the other hand, in order to open the bay window 1, it is sufficient to release the brake mechanism by operating a lift push button (not shown) that is separate from the above. It will automatically rise due to the force and open the bay window 1.

As described above, in the case of the present invention, although the bay window shutter is provided in the bay window 1, the drive motor 20 is not installed on the winding wheel 16 side at the upper end of the bay window 1 as in the conventional case. The actuating wire 25, which is provided on the bottom surface of the floor plate 4 on the lower end side and whose one end is connected to the seat plate 24 by driving the drive motor 20, is wound around the winding pulley 23 to resist the coil bomb 19. Since the shutter curtain 14 is configured to be forcibly lowered and closed, the shutter case 17 in which the winding wheel 16 and the like are housed can be constructed of a lightweight and compact one, and therefore There is no particular restriction on the installation space.

Moreover, in the bay window shutter 13 of the present invention, the operating wire 25 passes through the guide rail 15 and does not protrude outside, so there is no possibility that the operating wire 25 may get in the way or be seen from the outside. Never. Moreover, even if the operating wire 25 breaks for some reason, the shutter curtain 14 will not suffer from the problem of dropping under its own weight as in conventional shutters, and is therefore extremely safe.

[Operation and Effect] In short, the present invention is constructed as described above, and although it is a shutter for a bay window,
The drive mechanism for raising and lowering the shutter curtain will be placed below the bay window floor, rather than within the bay window ceiling as in the past. The ceiling can be small enough to accommodate a take-up wheel for winding up the shutter curtain. The drive mechanism for opening and closing can be installed by effectively utilizing the dead space below the floor of the bay window, which has little effect on securing the daylighting space. Therefore, the daylighting space of the bay window is almost sacrificed. You can install a shutter for a bay window without having to do so.

Moreover, this drive mechanism closes the shutter curtain by pulling it downward against the coil bullet, so if the operating wire that pulls the shutter curtain breaks for some reason, the shutter will not close. The curtain does not fall under its own weight, which improves safety, and when the curtain is fully closed, the brake mechanism is automatically activated to lock the winding wheel from rotating to feed out the wire. Therefore, when the electric motor is stopped after the shutter curtain is fully closed, there is no need to lock the shutter curtain up each time by locking the shutter curtain, resulting in extremely high operability. Become.

Furthermore, since the actuation wire is located inside the guide rail and is not exposed to the outside, the shutter curtain can be raised and lowered extremely smoothly without causing any problems or getting in the way. It is possible.
