Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shutter attached to an opening of a building body, and more particularly to a shutter suitable for being attached to the outside such as a bay window.

[0002]

2. Description of the Related Art Conventionally, a doorboard type rain door that is attached to the outside such as a sash window is stored in a door bag with a mirror plate, so that the door bag is attached to the outer wall of the building with a considerable thickness, and when the rain door is opened, It didn't look good.
Especially in Western style buildings, the door pocket attached to the outer wall had a design problem.

On the other hand, a winding type shutter using slats is designed to be attached to the upper part of the window. This type of shatter can be made relatively small because the height of the storage part is a retractable type, and in the case of a window with a low height, it can be designed like a window eaves, so many shutters can be used compared to conventional shutters. Have advantages.

However, even in the case of a shutter type shutter which is installed in a bay window, an unreasonable posture is compelled in order to stretch out and put the body forward in order to lower the shutter.
If the storage area is too high to reach,
There is a problem that a hook bar or a string must be used for opening and closing. Therefore, although an electric motor is used to open and close the door, it is expensive and not common.

Further, there is a problem in providing the upper wind-up type shutter on a window constituted by a plurality of planes having different angles such as a bay window. FIG. 4 is a plan view showing the contour of the bay window composed of three surfaces by a chain line. When the shutters are provided on the three faces of the bay window, the facing portions of the storage portions of the respective shutters indicated by A, B, and C compete with each other, so that it is necessary to provide a large gap L between the adjacent shutters. There is. Therefore, since no window can be formed in the portion of the interval L, there is a problem that not only the area of the window portion is substantially reduced but also the appearance is unfavorable.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and it is an object of the present invention to provide a shutter in which adjacent shutters can be arranged close to each other and can be smoothly opened and closed. It is intended.

[0007]

SUMMARY OF THE INVENTION According to the present invention, an upper winding type shutter and a lower winding type shutter are provided adjacent to each other in a shutter which is arranged adjacent to each other, and both are linked in a direction for weight balance. It is characterized by having done.

[0008]

According to the present invention, the upper winding type shutter and the lower winding type shutter are provided adjacent to each other,
The storage parts of the adjacent shutters are provided with the upper part at the lower part, and the storage parts are not arranged side by side.
In addition, since the interlocking direction of the adjacent shutters is a direction for balancing the weight, the shutters can be opened and closed lightly. If tension is applied to the lower roll-up type shutter in the direction of expansion, the lower shutter can be prevented from loosening during opening and closing.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 and 2 are for explaining one embodiment of a left-right interlocking shutter of the present invention. FIG. 1 is an explanatory view showing the overall arrangement of the shutter, and FIG. Is. In the figure, 1A and 1B are upper rotary shafts, 2B is a lower rotary shaft, 3A and 3B are upper wheels, 4B is a lower wheel,
5 is a chain, 6 and 7 are guide rollers, 8A is an upper take-up wheel, 9B is a lower take-up wheel, 10B is an energizing spring, 11A is an upper shutter, 12B is a lower shutter, 13B is an engaging portion, and 14B is a connection. A member, 15 is an interlocking shaft, and 16 and 17 are universal joints.

In this embodiment, the upper shutter 11A is provided with one unit at the center and the lower shutter 12B is provided with two units at the side. Hereinafter, the central portion is referred to as a shutter A, the right side is referred to as a shutter B, and the left side is referred to as a shutter C. Since the shutter C has a symmetrical structure with the shutter B,
The description is omitted.

The upper rotary shaft of the shutter A and the shutter B
The upper rotary shaft 1B is coupled with and interlocked with a universal joint 16. The lower rotary shaft 2B of the shutter B and the rotary shaft (not shown) of the shutter C are
It is interlocked via the interlocking shaft 15. The interlocking shaft 15 and the lower rotary shaft 2B are connected by a universal joint 17. However, in this embodiment, since the rotation axis is not on a straight line, a universal joint is used,
When the rotating shafts are aligned, the rotating shafts may be directly connected to each other, or the same rotating shaft may be used.

The end portions of the upper shutter 11A and the lower shutter 12B are respectively located at the upper winding wheel 8.
It is fixed to A and the lower winding wheel 9B and is guided by a guide rail (not shown). Lower shutter 12B
The seat plate portion is provided with an engaging portion 13B and engages with the chain 5. The seat plate portion of the upper shutter 11A is a free end.

The shutter A is housed in the upper winding portion, which has an upper wheel 3A and an upper winding wheel 8A. The upper wheel 3A and the upper winding wheel 8A are fixed to the upper rotary shaft 1A and are supported by appropriate bearings.

The shutter B is housed in the lower winding section, which has a lower wheel 4B and a lower winding wheel 9B. The lower winding wheel 9B is integrated by a connecting member 14B, and is rotatably supported by the lower rotating shaft 2B. A storage spring 10B is provided between the lower winding wheel 9B and the lower rotation shaft 2B. The lower wheel 4B is fixed to the lower rotary shaft 2B, and the lower rotary shaft 2B is supported by an appropriate bearing.

The chain 5 constitutes an interlocking mechanism, and the movements of the upper shutter 11A and the lower shutter 12B are interlocked via the upper wheel 3A and the lower wheel 4B. One end of the chain 5 is engaged with the seat plate portion of the lower shutter 12B, and the other end is fixed in the groove of the lower wheel 4B. The groove of the lower wheel 4B is provided in a spiral shape on the circumference, but may be a circular groove. Since the chain 5 is wound around the upper wheel 3A in a state of being laid on its side, the two wheels 3A and 4B rotate in directions opposite to each other. In this embodiment, the interlocking mechanism is not limited to a chain, but a wire-like body such as a wire or a belt can be used.

When the lower shutter 12B is lowered, the lower shutter 12B is wound around the lower winding wheel 9B, and the winding diameter thereof gradually increases. Therefore, the rotation angle of the lower rotary shaft 2B with respect to the lowered length becomes small,
The moving length of the chain 5 wound around the lower wheel 4B is also reduced. When the chain 5 is wound around the circumferential groove, a change in the relationship between the rotation angle of the lower wheel 4B and the movement amount of the chain 5 is also added. The same applies when the lower shutter 12B rises. However, since the lower shutter 12B and the chain 5 are engaged with each other, the movement amounts of the both must be equal. By providing the energy storage spring 10B between the lower winding wheel 9B and the lower rotating shaft 2B, tension is applied to the lower shutter 12B, and the difference in the moving amount can be compensated. Therefore, there is no reason why the energy storage spring must necessarily be provided between the lower winding wheel 9B and the lower rotating shaft 2B.
For example, by fixing the lower wheel 9B to the lower rotating shaft 2B,
When the lower wheel 4B is rotatably supported by the lower rotary shaft 2B, the energy storage spring 10B may be provided between the lower rotary shaft 2B and the lower wheel 4B. Alternatively, such as between the chain 5 and the engaging portion 13B, the chain 5
May be provided anywhere as long as the difference between the movement amount of the lower shutter 12B and the movement amount of the lower shutter 12B can be absorbed.

Since the shutter is opened and closed as described above, if the upper shutter 11A or the lower shutter 12B is moved up or down by hand, the shutters are opened and closed with the upper rotary shafts 1A and 1B. The lower rotary shaft 2B is interlocked with the lower shutter 12B or the upper shutter 1
1A can be lowered or rolled up. At this time, since the weights of the two shutters are interlocked with each other in a direction in which the weight is balanced, the shutters can be opened and closed lightly without requiring much force.

The upper wheel 3A is the upper rotary shaft 1
It may be fixed near the end of B on the shutter A side. The upper wheel 3B provided on the upper rotating shaft 1B is for interlocking with the chain on the opposite side of the shutter 12B.

FIG. 3 is an explanatory view showing the arrangement of the entire shutter of another embodiment of the left-right interlocking shutter of the present invention.
This embodiment is suitable for the case where the opening at the center is wide. A guide rail is provided at the center, the shutter A and the shutter B are divided into two parts, the shutter C and the shutter D are provided at the side. It is a thing. The details are the same as those described in FIGS. 1 and 2, but the upper rotary shaft of the shutter A and the upper rotary shaft of the shutter D are connected by the interlocking shaft 18, and the lower rotary shaft of the shutter B and the lower rotary shaft of the shutter C. The rotary shaft is interlocked with the interlocking shaft 19. Two upper winding type shutters and two lower winding type shutters are provided alternately.

The shutter B can be an upper roll-up type shutter and the shutter D can be a lower roll-up type shutter. Further, the shutter A and the shutter C may be linked, and the shutter B and the shutter D may be linked independently of this.

In the present invention, the weight balance between the upper roll-up type shutter and the lower roll-up type shutter does not necessarily have to be perfectly adjusted, and the upper roll-up type shutter and the lower roll-up type shutter are interlocked. It will be understood that due to the balanced weight, the opening and closing becomes lighter.

If the moving speeds of the upper winding type shutter and the lower winding type shutter are changed by, for example, making the diameters of the upper and lower winding wheels different, The height can be made different from that of the lower roll-up type shutter, and various designs can be realized.

[0023]

As is apparent from the above description, according to the present invention, the upper winding type shutter and the lower winding type shutter are arranged adjacent to each other so that they can be smoothly opened and closed. It has a powerful effect.
