BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bay window provided with a roll type shutter.

[0002]

2. Description of the Related Art FIGS.
This figure shows a bay window 2 having a roof portion 3, a main body portion 4 and a waist portion 5, each of which comprises a front portion a and sleeve portions b and c on both left and right sides thereof. The lift-up shutter is lifted upward from a lower storage section to cover an opening such as a window. The storage section contains a winding device for a shutter (hereinafter, the lift-up shutter is simply referred to as a shutter 1). I may say).

The shutter 1 is a roll- type shutter in which a large number of narrow slats are rotatably connected to each other and can be wound up and rewinded as a whole.
and the front shutter 1a and the sleeve shutter 1 (b, c) are independently formed corresponding to the a and the sleeve openings 6 (b, c) on both sides. 7a, sleeve shutter winding section 7 (b, c)
From the roof 3 to be unwound by a pulling device 8 housed in the roof 3, so that the opening 6 of the main body 4 is shielded.

[0004] The pulling device 8 of the roof 3 and the shutter 1 of each winding unit 7 are connected by a wire 9 or the like.
When the pulling device 8 is driven, the shutter 1 is pulled up along the guide grooves 12 formed in the ridges 10 and 11 of the main body 4. The winding of the shutter 1 is performed by a return spring incorporated in the shutter winding unit 7. The return spring is charged when the shutter 1 is rewound.

Not only the lift-up shutter 1 but also the bay window 2 provided with a so-called shutter is excellent in crime prevention, light-shielding properties and storm resistance, and is expected to be widely used. However, when a roll-type shutter is provided on the bay window 2, for example, if the front shutter winding section 7a and the sleeve shutter winding sections 7 (b, c) are arranged on the same horizontal plane, the winding diameter becomes large. 5, both ends of the front shutter take-up portion 7a interfere with the ends of the sleeve shutter take-up portions 7 (b, c), so that the front shutter take-up portion 7a and the sleeve shutter take-up portion 7 (b , C) are vertically shifted and stacked (FIG. 6), and the vertical dimension D of the waist 5 is large. This is the same in the case of the pull-down type roll shutter in which the winding unit 7 is housed in the roof unit 3.
In the vertical direction becomes large.

If the roof 3 and the waist 5 are large in the bay window 2 which accentuates the appearance of the house, the balance with the building design is generally deteriorated, and the appearance of the whole building may be impaired.

In a bay window provided with a roll-type shutter, a front shutter winding section and a sleeve shutter winding section are arranged so as to be shifted in indoor and outdoor directions in plan view. Smaller.

[0011]

1 and 2 show a first embodiment, which is a bay window 2 provided with a lift-up shutter 1. FIG. Bay window 2
It has a roof part 3, a main body part 4, and a waist part 5, each of which comprises a front part a and sleeve parts b, c on both left and right sides thereof.

The shutter 1 has a front opening 6 of the main body 4.
a and a shutter shutter 1 (b, c) corresponding to the opening 6 (b, c) on both sides of the front shutter 1a and the sleeve shutter 1 (b, c) independently. 7a, sleeve shutter winding section 7 (b,
It is wound up and stored in c). Hereinafter, for example, the front opening 6a and the sleeve openings 6 (b, c) on both sides are described.
May be collectively described as the opening 6.

The sleeve shutter take-up portions 7 (b, c) are located immediately below the left and right sleeve openings 6 (a, b), respectively, and both ends of the front shutter take-up portion 7a are at both ends.
In order not to interfere with the end of (c), it is shifted from directly below the front opening 6a to the indoor side in plan view (FIG. 2). Immediately below the front opening 6a, a small-diameter guide 13 (which may be a fixed guide that does not rotate) is arranged in parallel with the left-right direction of the front opening 6a. Both ends of the front shutter take-up section 7a and the sleeve shutter take-up section 7 (b, c)
Interference with the end of the is considered based on the maximum winding diameter,
In this embodiment, the rotation axis of the front shutter take-up portion 7a is shifted from the rotation axis of the guide 13 by about 150 mm toward the indoor side.

In this embodiment, the rotation axes of the front shutter take-up section 7a and the sleeve shutter take-up sections 7 (b, c) are arranged on the same horizontal plane, and the guide 13 is provided with a sleeve shutter take-up section. It is located below the taking part 7 (b, c) (FIG. 1). The body part 4 has erecting ridges 10 and 11 on the left and right on the outdoor side, and is fixed to the building frame by the left and right mounting frames 14 and 15 on the indoor side. The front opening 6a and the sleeve opening 6 (b, c) are defined by these partitions 10, 11 and the mounting frames 14, 15, and the left and right partitions 10,
Guide grooves 12 are formed on the opposing surface of the ridge 10 and the mounting frame 14 and on the opposing surface of the ridge 11 and the mounting frame 15, respectively. Each of the shutters 1 is guided up and down by both sides of the guide groove 12 and is moved up and down.

A pulling device 8 is housed in the roof portion 3 and is connected to an end of the winding portion 7 on the pull-out side of the shutter 1 by a wire 9. The winding unit 7 incorporates a rewind spring that is charged when the shutter 1 is pulled up.

In FIG. 1, reference numeral 16 denotes a shutter doorway, and reference numeral 17 denotes a lid. Lid 17 is shutter 1
When the shutter 1 is completely wound, the shutter door 16 is shielded.

When the pulling device 8 is operated in the forward direction, the shutter 1 is pulled up and rewound, and the opening 6 is closed. The front shutter 1a is a front shutter winding section 7.
a is guided downward from the sleeve shutter take-up portion 7b, and is directed upward by the guide 13, and is moved upward from the shutter entrance 15 of the front portion a. The sleeve shutters 1 (b, c) are directly guided from the respective winding portions 7 (b, c) to the shutter entrances 15 of the sleeve portions b, c, and are moved upward.

When the shutter 1 reaches the upper limit position, the limit switch is operated, and the brake of the pulling device 8 is operated. At the same time, the power supply to the motor is cut off, and the pulling operation stops. The shutter 1 is braked from returning (falling), and is maintained at a position blocking the opening 6. The brake is of a negative operation type that exerts a braking force when power is cut off.

When the pulling device 8 is operated in the reverse direction, the shutter 1 is pulled into the waist portion 5 by the force of the rewinding spring in the winding portion 7 and is wound on each of the winding portions 7. The force of the return spring is accumulated when the shutter 1 is pulled up. Note that even if the pulling device 8 is operated in the reverse direction as a whole, the motor is supplied with weak electric power in the forward direction, and a rapid drop of the shutter 1 is buffered.

In this case, the front opening 6a and the sleeve openings 6 (b, c) are simultaneously opened and closed. That is, in the pulling device 8, the front side mechanism and the sleeve side mechanisms on both sides are connected by a universal joint, and the front shutter 1a and both sleeve shutters 1 (a, b) are simultaneously pulled up and down.

In the above structure, the front shutter take-up portion 7a and the sleeve shutter take-up portions 7 (b, c) are shifted to the indoor side in a plan view so as not to interfere with each other. Since the shafts are arranged on the same horizontal plane, the vertical dimension D of the waist portion 5 is considerably smaller than in the conventional case where the waist portion 5 is vertically shifted and stacked. This makes it easy for the bay window 2 to match the design of the entire building.

FIG. 3 shows the second embodiment, and the arrangement of the front shutter take-up portion 7a and the sleeve shutter take-up portions 7 (b, c) is different from that of the first embodiment. Other configurations are the same as in the first embodiment. That is, the waist portion 5 has a front shutter winding portion 7a and a sleeve shutter winding portion 7 (b, c).
However, the front shutter take-up section 7a is the sleeve shutter take-up section 7
(B, c) are arranged such that they are shifted to the indoor side in plan view and do not interfere with each other.

However, these rotation axes are not arranged on the same horizontal plane, but are slightly shifted up and down.
Thereby, the guide 13 is moved to the sleeve shutter winding portion 7 (b,
c), so that the front shutter 1a unwound from the front shutter take-up section 7a can reach the shutter entrance 15 at a shorter distance than in the first embodiment, including the take-up section. The required length of the entire front shutter 1a is shortened. In the second embodiment, the vertical dimension D of the waist portion 5 is slightly larger than that of the first embodiment, but can be considerably reduced as compared with the conventional example. Also, there is little waste of the shutter body.

The above is an embodiment, and the present invention is not limited to the illustrated specific configuration. Sleeve shutter winding portions 7 (b, c) on both sides with respect to front shutter winding portion 7a
May be shifted indoors. In this case, the guide 1 is inserted into the waist 5 immediately below each sleeve opening 6 (b, c).
A guide corresponding to 3 is arranged parallel to the left and right direction of the sleeve opening 6 (b, c). In addition, as an embodiment, the roll-up type shutter in which the winding unit 7 is provided with the lift-up shutter 1 housed in the waist 5 has been described. In this case, the description is almost the same.

[0025]

[Effect of the Invention] In a bay window provided with a roll-type shutter for shielding the opening, the vertical dimension of the roof or waist can be reduced, and the bay window can be easily harmonized with the design of the building.
