Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to - a bay window provided to protrude outward from a wall of a building, and a shutter for shielding the window surface.

[Conventional technology]

BACKGROUND ART In recent years, a type of bay window has become popular, in which a finished product in which the window and the roof above the window are integrally assembled is fitted into an opening formed in the wall of a building.

When installing a shutter for this type of bay window, a winding shaft wrapped with the shutter curtain and an opening/closing machine that rotates the winding shaft in forward and reverse directions are installed on the roof formed above the bay window. I try to have everything built-in.

In the case of a three-sided bay window consisting of the front and left and right sleeves, each winding shaft is wound with a shutter curtain for the front and left and right ends of the winding shaft, and each winding is wrapped with a shutter curtain for the left and right sleeves, respectively. Either one end of the take-up shaft is coaxially connected (see Utility Model Application Publication No. 141484/1984), or each drive shaft that transmits the power of the opening/closing machine is coaxially connected to each of these take-up shafts via a sprocket. etc. (see Utility Model Application Publication No. 141485/1985).

Although it is not a bay window, a lightweight shutter type rain door is installed inside the rain door storage box that is installed protruding from the bottom of the window.
There are also windows in which the shutter curtain forming the shutter is lifted by hand and rolled out (Utility Model No. 55-1650)
(See Publication No. 94).

[Problem that the invention seeks to solve]

However, Utility Model Application No. 61-141484 and Utility Model Application No. 61-
As in Publication No. 141485, if the winding shaft and opening/closing machine for winding up the shutter curtain are all built into the roof of the bay window, only the roof becomes thicker (and at the same time,
Since the bay window mullions that support the weight of the roof have to be thick and sturdy, there is a drawback that the appearance of the bay window is significantly impaired.

In addition, when the winding shafts on the front and left and right sleeves or their drive shafts are coaxially connected and interlocked, the maximum operating angle between the mutually connected shafts must be kept at 4 Q': front and back. Therefore, there was an inconvenience that the left and right sleeves could not be provided at right angles to the front of the three-sided bay window.

For the same reason, the windows on the left and right sides are connected at right angles.
It was not possible to install two shutters on the front bay window.

Recently, constant velocity joints with a maximum operating angle of 90°5 have appeared, but when such joints are used to connect each winding shaft or each drive shaft, the length of the connection part is long. Therefore, the width of the mullion that separates two adjacent window surfaces must be increased accordingly, which impairs the appearance of the bay window.

Furthermore, if a box for housing a lightweight shutter-type storm door is attached so as to protrude outward from below the window, as in Japanese Utility Model Application Publication No. 55-165094, the overall appearance of the building will be significantly impaired.

Therefore, the present invention proposes to provide triple shutters or double shutters in a three-sided bay window in which the left and right sleeves are arranged at right angles to the front, and in a two-sided bay window in which the left and right sides are arranged at right angles, respectively. The technical challenge is to ensure that the exterior of the bay window with shutters and the exterior of the building as a whole is not impaired.

[Means to solve the problem]

In order to solve this problem, the bay window according to the present invention has a shutter curtain wound around a winding shaft built into the bottom part formed under the window, and a shutter curtain wound around a winding shaft. , a hoisting drum for hoisting a pair of hanging strips connected to both right and left ends of the starting end of the shutter curtain, and an opening/closing machine for rotating the drum in forward and reverse directions are built in, and the shutter curtain is mounted on the left and right mullions that define the window surface. It is characterized by being provided with guide rails that guide both left and right ends of the vehicle.

In addition, when this bay window shutter is a three-sided bay window consisting of the front and left and right sleeves, the shutter curtain for the front and the shutter curtain for the left and right sleeves cross each other at one end. They are characterized in that they are arranged at different levels, upper and lower.

Furthermore, if the window is a two-sided bay window consisting of a left side and a right side, the shank curtain for the left side and the shutter curtain for the right side are arranged at different levels above and below so that their ends intersect with each other. It is characterized by being

[Effect]

In the bay window according to the present invention, since the shutter curtain, which is bulky and heavy, is built into the base part formed under the window, the size of the roof part formed above the window can be reduced. At the same time, its weight can also be reduced.

Furthermore, if the weight of the roof is reduced, the mullions that support the roof can be thin and delicate, making the appearance of the bay window very smart and improving its appearance. Furthermore, by incorporating the shutter curtain into the pocket area formed under the window, the overall appearance of the building is not impaired.

In addition, when the bay window shutter is a double or triple shutter that blocks each window surface of a two-sided bay window or a three-sided bay window, each shutter curtain crosses one end with the adjacent shutter curtain. Since the shutter curtains are arranged in different levels, the distance between adjacent shutter curtains is narrowed, and the width of the mullions that define the window surface can be made very small. In addition, each shutter curtain is
Since the shutter curtains are arranged at different heights, they will never get in the way of other shutter curtains even if the distance between them is narrowed.

Furthermore, since the shutter curtain is unwound by being pulled by a pair of hanging strips connected to both right and left ends of its starting end, it can be provided at right angles to adjacent shutter curtains. Therefore, a square three-sided bay window with the left and right sleeves at right angles to the front of the window, and a two-sided bay window with the left and right sides of the window at right angles also have three shutters and two shutters, respectively. A shutter can be provided.

Note that each hanging strip 5 is made of a thin and strong metal tape or plastic tape, or a cloth tape used as a material for automobile seat belts.

Moreover, in the roof part 4, an opening/closing machine 7 is installed on the right sleeve part B side, and hanging strips connected to both left and right ends of the shutter curtain 3 for the right sleeve part B are connected to the front and rear of the opening/closing machine 7. A hoisting drum 6.6 for hoisting 5.5 is attached.

A bevel gear 11 provided at the tip of the drive shaft 10 of the opening/closing machine 7 drives a hoisting drum 6.6 for hoisting the hanging strips 5, 5 connected to both left and right ends of the shutter curtain 2 for the front A.
is meshed with a bevel gear 13 provided at one end of a drive shaft 12 to which a drive shaft 12 is attached, and both side moving shafts 10 and 12 are connected at right angles to each other and rotate coaxially.

Although not shown in the drawings, a drive drum 6.6 is attached to the other end of the drive shaft 12 for winding up the hanging strips 5.5 connected to both left and right ends of the shutter curtain 3 for the left sleeve section B. A bevel gear is provided that meshes with a bevel gear provided at one end of the shaft, and both side moving shafts are connected at right angles and rotate coaxially. In addition, the front A of the window surface and the left and right sleeve B.

If B is not at a right angle, a universal joint may be used in place of the bevel gear.

Next, the shutter curtain 2 for the front A and the left and right sleeve parts B
, B shutter curtains 3.3 have a front panel 1a and left and right side panels 1b of the base bag portion 1, respectively.

They are arranged horizontally along the inside of 1b, and are provided at different levels above and below, with their one ends intersecting each other at right angles.

As a result, the distance between the left and right ends of the shutter curtain 2 for the front A and one end of the shutter curtain 3.3 for the left and right sleeves B and B is significantly narrowed, and the distance between the front A and the left and right sleeves B and B of the window surface is significantly reduced. The width of the mullion 8 that separates the two can be made very small.

In addition, the base bag portion 1 has inspection lids 14a and 14b that can be attached and detached from the portion where the shutter curtains 2 and 3.3 are provided,
14b and a cushion is placed on the bottom plate 1c, it can be used as a bench seat. Moreover, if the remaining space on the bottom plate 1c is surrounded by a structure provided with a door or the like, it can be used as a storage space.

As described above, in the three-sided bay window according to the present invention, since the shutter curtains 2 and 3.3, which are large in size and weight, are built into the base bag part 1 formed under the window, they can be formed on the window. The size of the roof portion 4 can be reduced. especially,
If metal tape, plastic tape, etc. are used as the hanging strips 5.5 connected to the starting ends of each shutter curtain 2 and 3.3, the winding diameter of the winding drum 6 for winding up each hanging strip 5 can also be made very small. Therefore, the height of the roof portion 4 can be lowered to further reduce its size.

Moreover, since the weight of the roof part 4 is also very light, the mullions 8. L- can also be thin and delicate.

Therefore, as shown in FIG. 5, it is possible to make the appearance of the bay window smart and improve its appearance, and the shutter curtains 2, 3, and 3 are built into the base part 1 formed under the window. The overall appearance of the building will not be affected.

In addition, since each of the shutter curtains 2 and 3.3 is disposed vertically at different levels with one end crossing each other with respect to the adjacent shutter curtains, the distance between adjacent shutter curtains can be narrowed. Therefore, the width of each mullion 8 that separates the front A of the window surface and the left and right sleeve portions B, B can be made very small to make the window even smarter.

Further, since each shutter curtain 2 and 3 is unwound by being pulled by a pair of hanging strips 5, 5 connected to both left and right ends of the starting end, respectively, the shutter curtains 2, 3, and 3 are pulled out at right angles to the adjacent shutter curtains or It can also be provided at an acute angle.

Therefore, the left and right sleeves B with respect to the front A of the window surface.

It becomes possible to install three consecutive shutters in a three-sided bay window where B is provided at right angles.

In addition, since the shutter curtains 2 and 3, 3, which are hung from the hanging strips 5, 5 and are unwound upward, can be stopped at any height, they can be left in a half-open state as shown in Fig. 5. It can also be used as a blindfold to block the outside view and as a crime prevention effect.

Although not shown in the drawings, if the window surface is a triangular two-sided bay window consisting of a left side and a right side, a shutter curtain for the left side and a shutter curtain for the right side are installed in the base bag formed under the window. In addition to incorporating the shutter curtains, it is also possible to provide two shutter curtains by arranging the shutter curtains at different levels above and below so that their one ends intersect with each other.

Note that the hanging strip 5 is not limited to a tape shape, and may be a wire or the like.

〔Effect of the invention〕

As described above, according to the present invention, a three-sided bay window in which the left and right sleeves are provided at right angles to the front of the window surface, and a two-sided bay window in which the left and right sides are connected at right angles can also be used. In addition to being able to install triple shutters or double shutters, the size and weight of the roof of the bay window can be reduced, and the mullion that supports the roof can also be made thin and smart, making it possible to reduce the size and weight of the bay window and the entire building in which it is installed. It has a very excellent effect of significantly enhancing the appearance of the product.
