Description

Description: TECHNICAL FIELD The present invention relates to a shutter attached to an opening of a building frame, and more particularly to a shutter suitable for being attached to the outside of a window or the like.

(Prior art) Conventionally, shutter shutters and the like that are attached to the outside of a sash window or the like are housed in a door bag with a mirror plate. It didn't look good. Particularly in a Western-style building, the door pocket attached to the outer wall has a design problem.

On the other hand, a design in which a rewind-type shutter using a slat is designed to be attached to an upper portion of a window is being used. Shutters of this type have a retractable storage height that can be relatively small, and low-height windows can be designed like eaves on windows. Has advantages.

However, at the time of opening and closing, there is a problem that the storage portion is too high to reach, and a hook bar or a string must be used. For this reason, a motor that opens and closes using an electric motor has been developed, but it is expensive and is not common. In addition, since the length of the shutter becomes longer at the high opening, the winding diameter at the time of storage becomes large, and there is a problem that the storage part becomes large.

A similar mechanism for such a shutter is
The opening / closing door of a sink described in Japanese Patent Publication No. 702 uses a two-part shutter mechanism. If such a shutter mechanism is applied to a building shutter, the upper shutter can be moved up and down just by raising and lowering the lower shutter, so if you reach half the height, you can open and close the shutter. . However, when this mechanism is applied to a building shutter, the thickness and length of the shutter are larger than those of the sink, so the speed of the chain, which is the interlocking mechanism, and the speed of the shutter are changed by changing the winding diameter on the winding drum or shaft. And the winding becomes impossible. Further, it has been found that since the weight is significantly increased, a problem occurs in that the lower shutter is loosened.

(Problems to be Solved by the Invention) The present invention has been made in view of the above-mentioned circumstances, and by dividing the shutter into two parts vertically, the shutter can be easily opened and closed, and the slats are not loosened and smoothly. It is an object of the present invention to provide a shutter that can be closed.

(Means for Solving the Problems) According to the present invention, in a vertically split shutter, a storage section provided vertically in an opening of a building frame, a rotation axis arranged in the storage section, and a vertical rotation axis are provided. An interlocking mechanism for interlocking, an upper winding shaft arranged on the upper rotating shaft, a lower winding shaft arranged on the lower rotating shaft, and a shutter provided to be able to be wound on both winding shafts. And an elastic body for imparting tension to the lower shutter is interposed.

The elastic body is between the engagement portion of the lower shutter with the interlocking mechanism and the interlocking mechanism, between the lower winding shaft and the lower rotating shaft,
Alternatively, at least one between the lower rotating shaft and the interlocking mechanism.
It can be provided at a location.

(Operation) In the present invention, in the upper and lower splitter, a tension loop between the engaging portion and the rotating shaft at the time of opening / closing is provided by interposing an elastic body for applying tension to the lower shutter, that is, , The engagement portion, the lower shutter, the lower winding shaft, the lower rotating shaft,
The elastic body can absorb the tension or the compression force acting on the tension loop acting between the interlocking mechanisms, and can guarantee smooth opening and closing.

(Embodiment) FIG. 1 is a configuration diagram for schematically explaining an embodiment of the present invention, wherein 1 is an upper rotating shaft, 2 is a lower rotating shaft, 3 is an upper wheel, and 4 is a lower wheel. Wheels, 5 is a chain, 6 and 7 are guide rollers, 8 is an upper winding wheel, 9 is a lower winding wheel, 10 is an energy storage spring, 11 is an upper shutter, 12 is a lower shutter, and 13 is an engaging portion. .

The ends of the upper shutter 11 and the lower shutter 12 are fixed to the upper winding wheel 8 and the lower winding wheel 9, respectively, and are guided by guide rails (not shown). At the other end of the lower shutter, the engaging portion 13 is
At the engagement point shown as 14 in FIG.
Is engaged. The other end of the upper shutter may be engaged with the chain 5 or may be a free end without being engaged.

The upper wheel 3, the lower wheel 4, and the chain 5 form an interlocking mechanism, and the two wheels rotate in opposite directions in conjunction with each other because the chain is cross-linked. In addition,
Not limited to a chain, a string-like body such as a wire or a belt can be used. One of these cord-like bodies may be used as an endless, but as shown in the cross section in FIG. 2 (B),
A wheel having two grooves 15 and 16 is used as a wheel, and as shown in FIG. 3C, two wire-like bodies 17, 18 such as a wire and a belt are wound around each groove, respectively, and an end portion (× mark)
May be fixed to the bottoms of the grooves 17, 18. A spring for stretching and absorbing may be interposed in a part of the string-like body so as to cope with a change in the winding diameter of the string-like body.

The lower winding wheel 9 is connected to the lower rotating shaft 2 via a spring 10. When the lower shutter descends,
The lower shutter is taken up by the lower take-up wheel, and its winding diameter gradually increases. Therefore, the rotation angle of the lower rotary shaft 2 with respect to the lowered length is reduced, and the length of movement of a string-like body such as a chain wound around the lower wheel 4 is also reduced. When the string is wound around the wheel as described in FIG. 2, a change in the relationship between the rotation angle of the wheel and the amount of movement of the string is also added. The same applies when the shutter rises. However, since the lower shutter and the cord-like body are engaged, the movement amounts of both must be equal. By providing the energy storage spring 10, tension is applied to the lower shutter 12, and the difference in the amount of movement can be compensated. Therefore, there is no reason that the energy storage spring must always be provided between the lower take-up wheel 9 and the lower rotary shaft 2, and may be provided between the lower rotary shaft 2 and the lower wheel 4. It may be provided at any place where the difference between the amount of movement of the chain and the amount of movement of the shutter can be absorbed, such as between the 5 and the engaging portion 13.

Since the shutter is opened and closed as described above, the lower shutter is moved upward or downward by hand, and the rotation of the lower winding wheel accompanying the movement is transmitted to the upper winding wheel by the interlocking mechanism. The upper shutter can be lowered or hoisted, and since both shutters are balanced, opening and closing can be performed lightly without much power. It will be apparent that the upper shutter may be moved for opening and closing.

Further, the upper and lower shutters do not necessarily have to be completely divided into two, and one shutter may be shorter than the other. In that case, make the diameter of the shorter winding wheel smaller than the other, or consider an interlocking mechanism to give a difference in the rotation speed of the winding wheel, or do both. Is also good.

FIG. 3 to FIG. 6 are views for explaining a structure for attaching the building frame to the opening.

3 and 4 show an embodiment of the bay window type.
The figure is a vertical sectional view, and FIG. 4 is a horizontal sectional view. The same parts as those in FIG. 1 are denoted by the same reference numerals, and description thereof will be omitted. 19 is a seat plate of the upper shutter, 20 is a seat plate of the lower shutter, 21 is a sliding glass door, 22 is a rotating glass door provided on the left and right sleeves, 23 is a pillar which is a mounting portion of the building, 24
Is the upper storage cover, 25 is the lower storage cover, 26 is the top plate, 27
Is a main plate, 28 is a drain hole, and 29 is a guide rail. As described above, since the upper storage cover 24 and the lower storage cover 25 for storing the shutter are extended, the upper storage cover 24
The bottom storage cover 25 functions as a base plate of a bay window, for example, by being decorated with a flower pot, and has a good appearance.

5 and 6 show one embodiment of the internal type, FIG. 5 is a vertical sectional view, and FIG. 6 is a horizontal sectional view. 1, 3, and 4 are denoted by the same reference numerals, and description thereof is omitted. Because the shutter is divided into two parts, the winding diameter can be reduced, so in the case of a shutter that is mounted so that the shutter does not protrude to the outer wall of the building as in this embodiment, most of the storage part can be housed in the wall it can.

FIG. 7 is an explanatory view of the opening / closing state, in which the upper and lower shutters act as a weight balance with each other, so that the front opening state shown in FIG. 7A and the intermediate opening state shown in FIG.
(C) It can be stopped anywhere in the fully open state shown in the figure.

(Effects of the Invention) As is clear from the above description, according to the present invention, the shutter is divided into two parts and the lower shutter is provided with an elastic body for applying tension, so that the engagement part at the time of opening and closing is formed. The tension or compression force acting on the tension loop acting between the engaging portion, the lower shutter, the lower take-up shaft, the lower rotary shaft, and the interlocking mechanism between the and the rotating shaft can be absorbed by the elastic body. , Which can be smoothly opened and closed.

Further, since the shutter is divided into two parts, the winding amount can be reduced, and a spring having a weight balance is not required. Therefore, the storage portion can be reduced, and a shutter having a good appearance can be provided.
