Next, the first rocking mechanism 17 provided in the shutter 1 according to the first embodiment will be described by using the second rocking mechanism 18 and rocking mechanisms according to other embodiments as a representative. To do.
11 and 12 are a front view and a plan view of a main part of the first swing mechanism 17, and FIGS. 13 and 14 are a sectional view taken along the line AA and a sectional view taken along the line BB of FIG. FIG. 3 is an exploded perspective view of the same.

As shown in FIGS. 11 to 15, the swinging mechanism 17 includes a torsion bar 3 for converting the sliding force of the operating slider 15 into a rotational force, and a torsion bar 3 for transmitting the rotational force to the bar member 4. 1 transmission member 5 and its bar member 4
The second transmission member 6 transmits the rotational force of the to each slat 2.

The operation slider 15 has a knob 150.
And a slider body 151, and the slider body 151 is arranged so as to be linearly slidable along a slide frame 141 provided on the indoor-side concave surface 140 of the center frame 14. The slider body 151 has a hole substantially parallel to the slide frame 141, more specifically, a twisted hole 152 corresponding to the “twist” of the twist bar 3.
Is provided (see FIG. 13, FIG. 15, etc.) and its hole 1
The torsion bar 3 is inserted through 52. As shown in FIGS. 11 and 12, the slider body 151 includes
The slide frame 141 is formed into a substantially cubic shape.
Any shape may be used as long as it can be slid linearly along, for example, an oval shape. Similarly, the shape of the knob 150 of the spoiler 15 may be any shape. In this embodiment, the operation slider 1
The knob piece 150 of No. 5 faces the indoor side surface 142 of the middle frame 14, but may face the indoor side upper surface 143 or the lower surface 144 of the middle frame 14. The operation slider 15
It is possible to improve the convenience of the operation of and to improve the aesthetic appearance of the center frame 14.

The twist bar 3 is formed by deforming a thin plate-shaped bar material at a predetermined twist angle, and is adapted to rotate normally or reversely depending on the sliding direction of the operation slider 15. The twist angle of the twist bar 3,
That is, the rotation angle of the other end 31 with respect to the one end 30 of the torsion bar 3 formed by the twist angle allows the operator to lightly slide the operation slider 15 and enjoy a desired opening / closing angle. It may be molded so that the opening / closing angle of 2 can be finely adjusted.

For example, as shown in FIG. 16, with respect to the length L from one end 30 to the other end 31 of the torsion bar 3,
The rotation angle of the other end may be formed to be about 210 degrees.
With the same size L, the larger the rotation angle is set, the larger the opening / closing angle of the slat 2 can be made, but a large sliding force must be applied, and the operability becomes heavy. On the other hand, the smaller the rotation angle is set, the smaller the opening / closing angle of the slat 2 becomes and the lighter the operability becomes. Further, by adjusting the attachment length of the torsion bar 3 at the same rotation angle, the opening / closing angle of the slat 2 can be adjusted according to the slide width of the slide bar 15.

In this embodiment, the mounting length of the torsion bar 3 is set so that each slat 2 can be opened and closed within a range of about 90 degrees, and both ends 30, 31 of the torsion bar 3 are attached to the rotary shafts 32, 32. It is fixed and these rotary shafts 3
Reference numerals 2 and 32 are attached to bearings 33 and 33 fixed to the slide frame 141, respectively.

As shown in FIGS. 11, 12 and 15, the rotary shaft 32 has a fixed cylindrical portion 320 for fixing the end portion of the torsion bar 3 and the fixed cylindrical portion 320.
The rotating part 321 has a smaller diameter. This rotating part 3
A square hole 322 for fixing one end of the first transmission member 5 is formed in the hole 21. The step 323 formed between the fixed cylindrical portion 320 and the rotating portion 321 is the bearing 33.
By contacting the side surface of the torsion bar 3, the torsion bar 3 idles without displacement, and only the rotational force is transmitted to the first transmission member 5.

By interposing the rotary shaft 32 between the torsion bar 3 and the first transmission member 5, the torsion bar 3 can be smoothly rotated and the torsion bars 3 having different torsion angles can be easily replaced. Becomes

As shown in FIG. 12 and the like, one end 50 of the first transmission member 5 has a torsion bar 3 and a rotary shaft 32.
And the square hole 32 of the rotary shaft 32, which is arranged on the substantially same axis as
It is fixed to 2, and the other end 51 rotates about one end 50 thereof in response to the rotation of the torsion bar 3. The first transmission member 5 is formed in a substantially oval shape (see FIG. 1).
5)), and a rotation center portion corresponding to the one end 50,
Any shape may be used as long as it has a rotating portion corresponding to the other end 51.

The other end 51 of the first transmission member 5 is shown in FIG.
As shown in FIG. 2 and the like, it is attached to the hole 40 of the bar member 4 arranged along the vertical frame 13 so as to be idle.

The bar member 4 includes the first transmission member 5
Each slat 2 is rotated in synchronism with the rotation of the slat 2, and holes 41 corresponding to the arrangement intervals of each slat 2 are provided (see FIG. 15 and the like).

A second transmission member 6 formed in a substantially rhombus shape is arranged so as to correspond to the hole 41 of the bar member 4. One end 60 thereof is rotatably arranged on the vertical frame 13 via a slat holder 7 described later (FIG. 1).
5 etc.). The other end 61 of the second transmission member 6 is arranged so as to idle in each of the holes 41 of the bar member 4, and the second transmission member 6 has the one end 60 as a center, and the first transmission member 6 has the first end 60 as a center. It rotates in synchronization with the transmission member 5.

As shown in FIG. 15 and the like, the slat holder 7 is fixed to the rotary shaft 70 facing the inside of the vertical frame 13 coaxially with the rotary shaft 70 and on the outer surface of the vertical frame 13. It comprises a collar portion 71 that abuts and a wedge portion 72 that is embedded in the side surface of the slat 2.

As shown in FIG. 2 (c), a slat holder 7A for rotatably holding the other end of the slat 2 is attached to the vertical frame 12, and like the slat holder 7, The wedge portion 72 is embedded in the side surface of the slat 2.

Next, a structural example of the slat 2 will be described. As shown in FIG. 15 and the like, the slat 2 includes a hollow portion 21 provided with a mounting portion 20 for mounting the wedge portion 72 of the slat holder 7, and a plate-shaped portion extending downward from the lower portion of the hollow portion 21. 22 and is formed by extrusion molding of a metal material such as aluminum. The main characteristic point of this slat 2 is that when the slat 2 is rotated to a substantially horizontal position, the upper part of the slat 2 is a light-shielding piece 12 of the vertical frames 12, 13.
0, 130 (see FIG. 2 (C)), and the shape of the slat 2 so that the position of the rotating shaft 70 of the slat holder 7 and the center of gravity of the slat 2 substantially coincide with each other. That is, the sound deadening member 23 is attached to the outside of the upper chamber of the hollow portion 21.

When the slats 2 which can be opened and closed are attached to the vertical frames 12 and 13, a slight gap is formed at both ends of the slats, so that light from outside and light from inside the room leak. This is not desirable for crime prevention,
Light shielding pieces 120 and 130 are formed on the vertical frames 12 and 13. In order to avoid interference between the light blocking pieces 120 and 130 and the upper portion of the slat, the size of the hollow portion 21 of the slat 2 is set to the rotation center of the slat 2 (the one end 60 of the second transmission member 6, the rotation axis of the slat holder 7). 70) to the light-shielding pieces 120 and 130, so that the distance is shorter.

In this case, if the center of gravity of the slat 2 is biased toward the plate portion 22 side, the rotation of the slat 2 becomes heavy, which may impair comfortable operability. Therefore, a portion of the hollow portion 21 of the slat 2 that is closer to the light shielding piece from the center of rotation is formed to have a thick wall and a slight inclination so that the center of gravity thereof is not biased toward the plate portion 22 side. . As a result, the position of the rotating shaft 70 of the slat holder 7 and the center of gravity of the slat 2 are substantially coincident with each other, and the operability is improved.

The sound deadening member 23 is made of, for example, vinyl chloride, and when the slats 2 are closed, the sound deadening member 23 silences the sound generated when the upper and lower slats hit each other, and also exerts a rain proof function.

Next, the swing mechanism 1 configured as described above.
An example of use of No. 7 will be described with reference to FIGS. 17 (a) and 17 (b) are cross-sectional views of the main parts of the slats 2 closed, and FIG. 17 (c) is a cross-sectional view of the main parts of the slats 2 opened to approximately 45 degrees. ) Is each slat 2
FIG. 9 is a cross-sectional view of a main part in a state in which is opened at about 90 degrees.

The slats 2 are shown in FIGS. 17 (a) and 17 (b).
When in the closed state shown in FIG.
5 is at the leftmost position shown in FIG. When the operation slider 15 is slid to the right in the drawing from this position, the sliding force is applied to the torsion bar 3, the rotary shaft 32, the first transmission member 5, the bar member 4, the second transmission member 6, and the slat. The slat 2 is transmitted via the holder 7 and each slat 2 is opened at an angle corresponding to the slide width of the operation slider 15.

When the operating slider 15 is moved to an intermediate position as shown in FIG. 17C, the slat 2 is half opened, and the operating slider 15 is further slid to the right end as shown in FIG. 17D. Then, the slats 2 are fully opened.

When closing each slat 2, the operating slider 15 may be slid to the left. In addition,
If the "twist" of the torsion bar 3 is reversed, the slats 2 can be opened by sliding to the left.

As described above, in each of the above-mentioned operations, the slat 2 is opened and closed by sliding the operation slider 15 to the left and right, so that the opening and closing operation is extremely easy. Further, by reducing the twist angle of the torsion bar 3, it can be slid with a small force.
Further, each slat 2 can be fixed at any angle within a range of about 90 degrees. In this case, when it is desired to increase the opening / closing angle of each slat 2, the torsion bar having a larger twist angle may be replaced. Further, since the torsion bar 3 has a helix angle, even if the slat 2 is moved, the operation slider 15 is unlikely to slide, which is excellent in crime prevention. In particular, when the operating slider 15 is in the position shown in FIGS. 17A and 17B, it is difficult for the force applied to the slat 2 to be transmitted to the operating slider 15, and the closed state of the slat can be secured. ing.
Moreover, the manufacturing cost of the torsion bar 3 can be kept low. Further, since the light-shielding pieces 120 and 130 are formed on the left and right vertical frames 12 and 13, the crime prevention property is also excellent in this respect.

As shown in FIG. 2 (b), a door roller 8 is attached to the lower frame 11 and can be placed on a rail provided in the opening and stored in the door pocket or pulled out from the door pocket. It is like this.

In the first to third embodiments, the first and second swinging mechanisms are provided, but one swinging mechanism may be used to uniformly open and close the entire slat. .

In each of the above-mentioned embodiments, the operation slider 15, the torsion bar 3, the rotary shaft 32 and the first transmission member 5 are attached to the cross-shaped portion of the center frame 14 or the like, It may be attached to the frame 10 and the lower frame 11. In this case, the slats 2 may be arranged in place of the center frame 14. Further, the cross section is not limited to one, and may be a plurality. Further, the operation slider 1 is provided without providing the cross section.
5, a box capable of accommodating the torsion bar 3, the rotating shaft 32, and the first transmission member 5 may be exposed to the inside of the room.

By interposing a member for moving in the direction orthogonal to the rotating direction of the rotating shaft 32 between the rotating shaft 32 and the first transmitting member 5, the operating slider 1
5, the torsion bar 3 and the rotary shaft 32, the vertical frame 12,
It can also be arranged on the 13 side.

In each of the above-described embodiments, the slats are arranged on the substantially entire surface of the shutter frame, but the slats are limited to a predetermined area such as the upper part, the middle part or the lower part of the shutter frame. An oscillating mechanism may be provided. The slats may be arranged vertically instead of horizontally.

[004]

According to the first aspect of the invention, when the slats are closed, the functions of crime prevention, rain protection and wind protection can be achieved, and when the slats are opened, ventilation, ventilation and daylighting are possible. Since a torsion bar that converts the sliding force into a rotational force is used, the device that applies the sliding force can be compactly housed in the shutter door frame.By adjusting the twist angle of the torsion bar, the strength of the sliding force application, The operating portion can adjust the swing angle (opening and closing angle) of the slat, can keep the slat stationary at an opening and closing angle as desired, and even if the slat is moved in that state, the force is difficult to be transmitted to the torsion bar. Since the mounting position can be changed according to the size of the shutter and the installation place, the operation portion can be arranged at a position where a resident or the like can easily operate.

According to the second aspect of the present invention, the crosspiece is provided in the sliding door frame, and the operating portion is arranged on the crossing so that the operation can be performed at a position in harmony with the design of the sliding door frame. Parts can be provided. Further, when the size of the shutter is large, the cross section also has the effect of reinforcing the strength of the shutter frame. Well
As in the invention according to claim 3, the rain door is a door bag.
It can be stored or pulled out from the door pocket.
