The shutter of the present invention according to the first embodiment will be described in detail with reference to the drawings.
Fig. 1 is a front view of the outdoor side of the shutter with each slat closed, Fig. 2 (a) is a front view of the indoor side of the shutter, Figs. 2 (b) and 2 (c) are illustrations of a part omitted, and an enlarged view of the shutter. 3 and 4 are a front view and a plan view of the main part of the swing mechanism, and FIGS. 5 and 6 are sectional views taken along arrows AA and BB in FIG. FIG. 7 is an exploded perspective view of the same.
Note that the same reference numerals are used for the same components in the respective drawings and the drawings described later, and detailed description thereof is omitted.
[0014]
As shown in FIGS. 1 and 2, the shutter 1 is arranged in a horizontal manner in shutter doors 10 and 11, left and right rods 12 and 13, and a middle rod 14. An operation slider 15 for operating a swing mechanism, which will be described later, is faced to the collar 14.
When the operation slider 15 is slid in the left-right direction on the surface of FIG. 2, the slats 2, 2, 2,...
As described above, the swing mechanism that opens and closes the slat 2 operates by the sliding motion of sliding the operation slider 15 to the left and right, so that the ease of the swing operation of the slat 2 is improved.
Further, as shown in FIG. 4 and the like, the operation slider 15 is accommodated within the width in the prospective direction so as to be compact, and it is easy to route the shutter 1 when entering and leaving the door pocket. ing.
[0015]
As shown in FIGS. 3 to 7, the swing mechanism includes a torsion bar 3 that converts the sliding force of the operation slider 15 into a rotational force, and a first transmission member that transmits the rotational force to the bar member 4. 5 and a second transmission member 6 that transmits the rotational force of the bar member 4 to each slat 2.
[0016]
The operation slider 15 includes a knob 150 and a slider main body 151, and the slider main body 151 is arranged so as to be able to slide linearly along a slide frame 141 provided on the indoor concave surface 140 of the intermediate collar 14. Yes.
The slider body 151 is provided with a hole 152 (see FIG. 5 and the like) substantially parallel to the slide frame 141, and the torsion bar 3 is inserted into the hole 152.
As shown in FIGS. 3 and 4, the slider main body 151 is formed in a substantially cubic shape, but any shape can be used as long as it can slide linearly along the slide frame 141. For example, an oval shape may be used.
[0017]
The torsion bar 3 is obtained by deforming a thin plate-shaped bar with a predetermined twist angle, and is configured to rotate forward or reverse depending on the sliding direction of the operation slider 15.
The magnitude of the torsion angle of the torsion 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 torsion angle, allows the operator to slide the operation slider 15 lightly. What is necessary is just to shape | mold so that the opening / closing angle can be enjoyed and the opening / closing angle of each slat 2 can be finely adjusted.
[0018]
For example, as shown in FIG. 8, the rotation angle of the other end may be formed to be about 210 degrees with respect to the length L from one end 30 to the other end 31 of the torsion bar 3.
In the same dimension L, the larger the rotation angle is set, the larger the opening / closing angle of the slat 2 is. However, 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 and the lighter the operability.
Moreover, the opening / closing angle of the slat 2 can be adjusted by adjusting the mounting length of the torsion bar 3 at the same rotation angle.
[0019]
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 and 31 of the torsion bar 3 are fixed to the rotary shafts 32 and 32. At the same time, these rotary shafts 32 and 32 are attached to bearings 33 and 33 fixed to the slide frame 141, respectively.
[0020]
As shown in FIGS. 3, 4, and 7, the rotating shaft 32 includes a fixed cylindrical portion 320 that fixes the end of the torsion bar 3, and a rotating portion that is reduced in diameter from the fixed cylindrical portion 320. 321.
The rotating portion 321 is formed with a square hole 322 that fixes one end of the first transmission member 5.
When the step 323 formed between the fixed cylindrical portion 320 and the rotating portion 321 contacts the side surface of the bearing 33, the torsion bar 3 is idled without being displaced, and only the rotational force is the first transmission member. 5 is transmitted.
[0021]
In addition, by interposing the rotating shaft 32 between the torsion bar 3 and the first transmission member 5, the torsion bar 3 can be smoothly rotated and the torsion bar 3 having a different torsion angle can be easily replaced.
[0022]
As shown in FIG. 4 and the like, one end 50 of the first transmission member 5 is disposed on substantially the same axis as the torsion bar 3 and the rotation shaft 32, and is fixed to the square hole 322 of the rotation shaft 32. The other end 51 rotates around the one end 50 according to the rotation of the torsion bar 3.
The first transmission member 5 is formed in a substantially oval shape (see FIG. 7 and the like). However, if the first transmission member 5 includes a rotation center portion corresponding to the one end 50 and a rotation portion corresponding to the other end 51. Any shape is acceptable.
[0023]
As shown in FIG. 4 and the like, the other end 51 of the first transmission member 5 is attached to the hole 40 of the bar member 4 arranged along the flange 13 so as to be idled.
[0024]
The bar member 4 rotates each slat 2 in synchronization with the rotation from the first transmission member 5, and is provided with holes 41 corresponding to the arrangement interval of the slats 2 (see FIG. 7 and the like). ).
[0025]
On the other hand, one end 60 of the second transmission member 6 formed in substantially the same shape as the first transmission member 5 so as to correspond to the hole 41 of the bar member 4 passes through a slat holder 7 described later. It arrange | positions rotatably at the said collar frame 13 (refer FIG. 6 etc.).
The other end 61 of the second transmission member 6 is disposed in the holes 41 of the bar member 4 such that the second transmission member 6 can idle. The second transmission member 6 is centered on one end 60 of the first transmission member 6. It rotates in synchronization with the transmission member 5.
[0026]
As shown in FIG. 7 and the like, the slat holder 7 has a rotating shaft 70 facing the inside of the flange 13, a flange fixed coaxially to the rotating shaft 70, and abutting against the outer surface of the flange 13. It consists of a part 71 and a wedge part 72 embedded in the side surface of the slat 2.
[0027]
2C, the slat holder 7A for rotatably holding the other end of the slat 2 is attached to the flange 12, and is configured in the same manner as the slat holder 7. The wedge portion 73 is embedded in the side surface of the slat 2.
[0028]
Next, a configuration example of the slat 2 will be described.
As shown in FIG. 7 and the like, the slat 2 includes a hollow portion 21 provided with a mounting portion 20 for attaching the wedge portion 72 of the slat holder 7, and a plate-like portion extending downward from the lower portion of the hollow portion 21. 22 and formed by extrusion molding of a metal material such as aluminum.
The main characteristic point of the slat 2 is that when the slat 2 is rotated to a substantially horizontal position, the upper part thereof does not interfere with the light shielding pieces 120 and 130 (see FIG. 2C) of the flanges 12 and 13. That is, the sound deadening member 23 is attached to the outside of the upper chamber of the hollow portion 21.
[0029]
When the slats 2 that can be opened and closed are attached to the flanges 12 and 13, a slight gap is formed at both ends of the slats, and light from the outside and light from the indoor side leaks.
Since this is not preferable in terms of crime prevention, light shielding pieces 120 and 130 are formed on the ridges 12 and 13. In order to avoid interference between the light-shielding pieces 120 and 130 and the upper portion of the slat, as shown in FIG. 2 and the like, the dimension of the hollow portion 21 of the slat 2 is set to the rotation center of the slat 2 (the second transmission member 6 of the second transmission member 6). It was formed to be shorter than the distance from the one end 60) to the light shielding piece.
[0030]
The muffling member 23 is made of, for example, vinyl chloride. When the slats 2 are closed, the muffling member 23 mutes the sound generated when the upper and lower slats hit, and also exhibits the function of rain.
[0031]
As shown in FIG. 2 (b), a door pulley 8 is attached to the lower arm 11, and it can be placed on a rail provided in the opening and stored in or pulled out of the door pocket. ing.
[0032]
Next, a usage example of the shutter configured as described above will be described with reference to FIGS.
9 (a) and 9 (b) are cross-sectional views of the main parts when the slats 2 are closed, and FIG. 9 (c) is a cross-sectional view of the main parts when the slats 2 are opened at approximately 45 degrees. ) Is a cross-sectional view of the main part in a state in which each slat 2 is opened at approximately 90 degrees.
[0033]
When the slat 2 is in the closed state shown in FIGS. 9A and 9B, the operation slider 15 is in the right end position shown in FIG.
When the operation slider 15 is slid to the left in the drawing from this position, the sliding force is generated by the torsion bar 3, the rotary shaft 32, the first transmission member 5, the bar member 4, the second transmission member 6, and the slats. The slats 2 are transmitted to the slats 2 through the holders 7, and each slat 2 is opened at an angle corresponding to the slide width of the operation slider 15.
[0034]
When the operation slider 15 is moved to an intermediate position as shown in FIG. 9C, the slat 2 is half-opened. When the operation slider 15 is further slid to the left end as shown in FIG. 2 is fully open.
[0035]
When each slat 2 is closed, the operation slider 15 may be slid to the right.
[0036]
As described above, in each of the above operations, the slats 2 are opened and closed by sliding the operation slider 15 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 a desired angle within a range of approximately 90 degrees. In this case, when it is desired to increase the opening / closing angle of each slat 2, it may be replaced with a torsion bar having a larger twist angle.
Further, since the torsion bar 3 has a twist angle, the operation slider 15 is difficult to slide even when the slat 2 is moved, and is excellent in crime prevention.
Moreover, the torsion bar 3 can suppress the manufacturing cost at a low cost.
Further, by forming the torsion bar 3 in the reverse direction (counterclockwise), the slat 2 is opened when the operation slider 15 is in the position shown in FIGS. 9A and 9B. Can be.
Further, since the light shielding pieces 120 and 130 are formed on the left and right ridges 12 and 13, the crime prevention property is excellent also in this respect.
[0037]
Next, a second embodiment will be described based on FIG.
The shutter 1A of the second embodiment is different from the shutter 1 of the first embodiment in that the swing mechanism is arranged on the right side when viewed from the indoor side.
By combining the shutter 1 according to the first embodiment and the shutter 1A according to the second embodiment, it is possible to provide a user-friendly shutter according to the demands of the consumer. For example, when two shutters are used, the operation sliders 15 and 15 can be adjacent to each other using the shutter 1 and the shutter 1A.
Since the other configuration is the same as that of the shutter 1 of the first embodiment, the same operational effects can be obtained.
[0038]
Next, a third embodiment will be described based on FIG.
The shutter 1B according to the third embodiment is different from the shutter 1 according to the first embodiment in that the swing mechanism is divided into upper and lower parts and the slats 2 between the upper rod 10 and the middle rod 14 are swung. And a second rocking mechanism for rocking each slat 2 between the lower rod 11 and the middle rod 14 is provided.
According to the shutter 1B, the upper and lower swing mechanisms can be operated simultaneously or the upper or lower swing mechanism can be operated separately according to the installation environment.
Since the other configuration is the same as that of the shutter 1 of the first embodiment, the same operational effects can be obtained.
[0039]
In each of the embodiments, the operation slider 15, the torsion bar 3, the rotating shaft 32, and the first transmission member 5 are attached to the middle rod 14, but are attached to the upper rod 10 and the lower rod 11. May be. In this case, the slats 2 may be disposed in place of the intermediate collar 14.
Further, by interposing a member that makes the rotation direction of the rotation shaft 32 orthogonal to each other between the rotation shaft 32 and the first transmission member 5, the operation slider 15, the torsion bar 3, and the rotation shaft 32 are connected to each other. It can also be arranged on the side.
In each of the above embodiments, the slats are disposed on substantially the entire surface of the shutter, but the slats are swung only in a predetermined region such as an upper part, a middle part, or a lower part of the shutter. A swing mechanism may be provided.
[0040]
Next, an embodiment according to another example of the swing mechanism (hereinafter referred to as a fourth embodiment) will be described with reference to FIG.
The feature of this fourth embodiment is that the knob 150 of the operation slider 15A constituting the swing mechanism is attached to the upper surface of the slider body 151 so that it is parallel to the in-frame direction X of the shutter 1 and the like. It is arranged in. The slider body 151 is preferably provided with a torsion-shaped hole 152 corresponding to the “twist” of the torsion bar 3, and the torsion bar 3 is inserted into the hole 152.
If the swing mechanism having such a structure is attached to the middle rod 14, the upper rod 10, the lower rod 11, or the left and right rods 12, 13, the knob piece 150 does not protrude from the width of each rod. Can be made more thorough.
Other configurations are substantially the same as those of the above-described embodiments, so that the same operational effects can be achieved.
[0041]
Next, an embodiment (hereinafter referred to as a fifth embodiment) according to another example of the swing mechanism will be described with reference to FIGS. 13 and 14.
The feature of the fifth embodiment is that an operation slider 15B is provided by attaching "rattle prevention means" to the operation slider 15 constituting the swing mechanism.
[0042]
The slider main body 151 constituting the operation slider 15B includes a main body portion 151a, a lid body portion 151b, and a crimping portion 151c that caulks the main body portion 151a and the lid body portion 151b.
And after setting the said torsion bar 3 in the said torsion-like hole 152 each provided in the said main-body part 151a and the cover body part 151b, it is made to fix with the crimping part 151c.
Note that the knob piece 150 is fixed to the caulking portion 151c.
[0043]
The reason why the “backlash prevention means” is attached to the operation slider 15B and a configuration example will be described.
When the twisted hole 152 is faithfully formed along the “twist” of the torsion bar 3, “play” occurs when the operation slider 15 is operated. In addition, it is difficult to form exactly the same “twist” in all the torsion bars 3.
Therefore, a clearance (play) is required for the torsion bar 3 in the torsional hole 152. In this case, a device that adjusts the clearance and realizes a comfortable sliding operation is a “rattle prevention means”.
[0044]
The “rattle prevention means” is configured by fitting springs 151e and balls 151f into two rows of holes 151d and 151d provided in the main body 151a.
The operation of the “rattle prevention means” will be described with reference to FIG. 15. The ball urged toward the lid portion 151b by the spring 151e abuts on the torsion bar 3 and is rotated by the slide of the operation slider 15B. To do.
As a result, the clearance C that is inserted into the torsion-shaped hole 152 and acts on the torsion bar 3 is appropriately adjusted, and the slider body 151 is smoothly slid without generating “backlash”. Can do.
