Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a shutter having a sliding door. [Background Art] Conventionally, when a person enters or exits with the shutter fully down, the inconvenience of having to lift the shutter each time to sneak through is difficult. There was no other way. Furthermore, if the user wants to go out, there is the inconvenience of having to lower the raised shutter again.

If the shutter is heavy, it is even more inconvenient to raise and lower it. Therefore, this inventor invented a shutter that is equipped with a sliding door and is also retractable. With this invention, the inconveniences described in item 2 have been improved.

However, if one forgets to be careful, there is a risk that the sha-doyu will be stored with the submerged door not fully closed, and this was an issue that needed to be improved.

[Purpose of the invention]

Therefore, an object of the present invention is to provide a shutter with a sliding door that cannot be stored when the sliding door is in an openable (usable) state. [Disclosure of the Invention] The inventor has achieved the above object. In order to achieve this goal, we conducted intensive research and completed this invention.

This invention is a shutter in which a plurality of slats are parallel to each other, and the slats are separated so that an opening for a furnace is formed at a desired position, and one locking mechanism is provided on both sides of the shutter body. When one of the interlocking mechanisms crosses the door and the locking mechanism is in the locked state, a temporary lock is released at the joint between the door and the shutter body. The gist is a shutter characterized by being divided into two parts. Hereinafter, this will be explained in detail with reference to the drawings, with reference to the drawings.

FIG. 1 is a model view of the internal structure of the shutter when it is fully closed, viewed from indoors. As you can see in this figure, multiple slats are parallel to each other, and the sliding door 2
The slats 1, 1 are arranged so that an opening is formed at the position where
．． 1 is separated. In the figure, la, lb, and lc are the slats that form the sliding door. Near the center of the shutter on the side of the door 2, there is an operating section 3 for operating the door 2 between an openable state and an unopenable state by rotating a lever 4.
is provided. The lever 4 of the operating section is operated from the inside of the shutter room.

The operation unit 3 has two wires 4a, 4 as its interlocking mechanism.
It has b. A locked portion 6 is locked to a locking portion 5a on the indoor side of the shutter side end via one wire 4a.
It is connected to a. The locking portion 5a and the locked portion 6a are a locking mechanism of the shutter. In addition, the operating section 3 is connected to the blade section 8 at the opposing position via the other Y (.4b).
It is connected to a pivot body 7 provided with a and 8b. The upper wing plate portion 8a is connected to the wire 4b, and the lower wing plate portion 8b is pivotally attached to the central end of the seat vine of the horizontal bar 9 for opening the door 2. FIG. 2 is a partially cutaway partial front view of the shutter when viewed from the outside of the room. As seen in this figure, the horizontal bar 9 is connected to one end of the fixed spring 15.

Since the other end of the fixed spring 15 is attached to the fixed plate 15a fixed inside the slat, the restoring force of the fixed spring 15 can potentially reduce the pulling force toward the center of the shutter (in the direction of the arrow). I am receiving it.

The horizontal bar 9 has a U-shaped cross section and has planar ends at both ends. In the figure, 9a is a guide portion that guides the horizontal bar 9. A long rod 10 is housed inside the door 2 and is pushed by the horizontal rod 9 and moves inside the door 2 toward the side of the shutter (in the direction of the chain arrow). Like the horizontal bar 9, the long bar 10 has a U-shaped cross section and has planar ends at both ends. Further, it is guided by a guide portion 10a located at the center of the shutter inside the sliding door 2. This guide portion 10a is provided with a fixed spring 16, which is connected to the long bar 10 and urges the long bar 10 toward the center of the shutter. The long bar 10 has protrusions 31, 31 in the middle. The projecting pieces 31, 31 are received by the guide portion 10a, thereby preventing the long bar 10 from unnecessarily protruding toward the center of the shutter, and preventing the long bar 10 from being pushed by the horizontal bar 9. Sometimes it fits inside the hidden door 2. A horizontal bar 11 having the same shape as the horizontal bar 9 is provided at the tip of the long bar 10 (on the opposite side of the horizontal bar 9 across the long bar 10). In the figure, 10b is the guide part of the long bar 10, lla
is a guide portion of the horizontal bar 11.

A pivot mount 12 having the same shape as the pivot mount 7 is provided on the upper part of the horizontal bar 11 so as to face the pivot mount 7 . Pivot body 12
The lower blade plate portion 13b is pivotally attached to the end of the horizontal bar 11 in the shutter outward direction, and the horizontal bar 11 can be moved from side to side by following the rotation of the main body of the pivoting body 12. There is. As shown in FIG. 1, a portion of the wing plate portion 13a of the pivoting body 12 is a locked portion that is engaged with a locking portion 5b located on the indoor side of the shutter side end via a wire 14. It is connected to 6b. Although the locked portion 6b and the locking portion 5b are opposite in direction, they have the same shape and structure as the locked portion 6a and the locking portion 5a, and serve as a locking mechanism for the shutter. That is, as shown in FIGS. 3 and 4, the locked portion 6b is always biased in the outward direction of the shutter (in the direction of the arrow in the figure) by the torsion spring 39, and the inverted-shaped piece 60 is pushed against the guide column. 40
(Also shown in Fig. 1) A force is acting to push it. The locking portion 5b projects downward in an inclined manner so that the locking portion 6b does not get in and pull out upward when the locked portion 6b descends while contacting the guide column 40 (when the shutter is lowered). ing. In the drawings, it has a groove shape, and there is also an inclined protrusion 50 at the bottom, but this need not be provided. In these figures, 2 is a sliding door, 12 is a pivot body, 1
4 is a wire, and 41 is a wall.

Next, a mechanism related to opening and closing of the hidden door 2 will be explained based on FIG. The sliding door 2 is provided with a handle 17. At the back of the handle 17, an upward bar 19 extending upward and a downward keyring 20 extending downward are pivotally attached at one end to the peripheral edge 18 of the axis serving as the center of rotation. As shown in FIG. 5, the upward rod 19 and the downward rod 20 each have a cross-sectional shape,
The other end of each is flat. The other ends of the upward rod 19 and the downward rod 20 are opposed to the tips of the downward rod 22 and the upward rod 25, respectively, which have the same cross-sectional shape. These tips are also planar.

The downward rod 22 has its upper end pivotally connected to one end of a pivot body 21 having a boomerang-shaped plate. Similarly,
The lower end of the upward bar 25 is pivotally connected to one end of a pivot body 24 having a boomerang-shaped plate. Pivot body 21.
The other end of 24 is the slat la, l of the part that will become the sliding door 2.
From c to the other ends of horizontal bars 23 and 26, which are opening members, are releasably connected laterally to the slats 1.1 of the shutter body. These horizontal bars 23, 26 have a cross-sectional shape. An extension piece 27 extends obliquely downward from the axial peripheral edge 18 of the handle 17. At the tip of the extending piece 27, one end of a horizontal bar 2B having an opening-shaped cross section and serving as an opening member like the horizontal bars 23 and 26 is pivotally attached.

As shown in FIGS. 5 and 1, the upward bar 25 pivoted to one end of the pivot body 24 below the sliding door 2 is
It is connected to one end of the fixed spring 35, and is always connected to the shaft peripheral edge 1.
It is receiving a force that pulls it in the direction of 8. Fixed spring 35
is fixed to the guide portion 25a of the upward bar 25.

In the figure, 26a and 26b are guide parts that guide the horizontal bar 26 for opening. A recess 36 is provided on the upper surface of the open horizontal bar 28 near the shaft peripheral edge 18 on the side closer to the shaft peripheral edge 18 . The recess 36 is a portion into which a protrusion near the tip of the spring piece 28b attached to the guide portion 28a of the horizontal bar 28 enters. This serves as a lock when the horizontal bar 28 is in the bolted state. As shown in FIGS. 1 and 6, the downward rod 22, which is pivoted to one end of the pivot mount 21 above the sliding door 2, is connected to one end of the fixed spring 34, and is always connected to the shaft peripheral edge 18. It is being subjected to a pulling force in the direction of . The fixed spring 34 is attached to the downward bar 2
It is fixed to the guide portion 22a of No. 2. In the figure, 19a is a guide portion 23a of the upward rod 19.

23b is a guide portion of the horizontal bar 23 for opening.

As shown in FIGS. 5 and 6, notches 29 are provided near the tips of the upward bar 25 and the downward bar 22. As shown in FIGS.

As can be clearly seen from FIG. 7, each notch 29 is a portion that receives a pin 31 at the tip of a cam 30 which is fixedly and pivotally connected to the slat 1a or lc. Further, the vicinity of the pin 31 is pulled by a fixed spring 32. In FIG. 7, 37 is a fixing plate that fixes the fixing spring 32. The pin 31 of the cam 30 is pulled by the fixing spring 32 and enters the inner part 33 (shown in FIG. 7) of the notch 29 when the horizontal bar 23 or 26 is in a barring state. This prevents the pin 31 from moving with a small amount of force, so that the downward bar 22 and the upward bar 25 do not protrude into the adjacent slat 11) as the slant is bent during storage.

Next, the operation of the above embodiment will be explained.

As shown in FIGS. 1 and 2, when the shutter is lowered, the locking portions 5a and 5b on both sides of the shutter engage the locked portion 6a.
, 6b are locked, and the shutter is prevented from rising. At this time, the interlocking mechanism that connects the operating section 3 and the locking mechanism is
The connection between the horizontal bar 9 and the long bar 10 and between the long bar 10 and the horizontal bar 11 is interrupted, and the connection is temporarily released at the joint between the sliding door 2 and the shutter body. In order to open the hidden door 2, it is sufficient to simply turn the handle I7 shown in FIG. 1 in the clockwise direction (in the direction of the arrow 0). Due to this rotation, the bidirectional rod 1 which is pivotally connected to the axial peripheral portion 18 of the handle 17
9 and downward bar 20 are respectively retracted toward the handle, as seen in FIG. 5 or 6. This results in
The downward bar 22 and the upward bar 25, which had been pushed into the upward keyaki 19 and the downward bar 20, respectively, extend toward the handle due to the restoring force of the respective springs 34 and 35,
Put a bar between the slats inside the sliding door 2. According to the movement of the downward bar 22 and the upward bar 25, the barred horizontal bars 23, 26 move back into the door 2 and unbar. Further, as shown in FIG. 1, the extending piece 27 extending from the shaft peripheral portion 18 rotates as the handle 17 rotates. Along with this, the horizontal bar 28 is also unbarred and retreats into the subdoor 2. In this way, the door 2
The bolt between the shutter and the shutter body disappears, resulting in an open state.

To close the door 2, the handle 17 may be rotated in the opposite direction. The horizontal bars 23, 28, and 26 each bar the lateral shutter body side slats 1, and release the bar in the sliding door 2 in the contraction direction.

When storing the shutter, first, as shown in FIG. 1, the lever 4 of the operating section 3 is rotated in the direction of the arrow. As a result, as shown by the chain line, the first part 6a of the engaged part I, which is connected to the operating part 3 via the wire 4a, is pulled by the wire 4a and comes out of the locking part 5a, releasing the locked state. By pulling the other wire 4b of the operating section 3,
As shown in FIG. 2, the pivot body 7 rotates and the horizontal bar 9 moves in the direction of the sliding door 2 to lock the door. The long bar 10 is pushed by the horizontal bar 9 and protrudes to the outside of the door 2 to be bolted. The long bar 10 further pushes the horizontal bar 11. As the horizontal bar 11 moves in the outward direction of the shaft 4 and the ivy, the pivot body 12 rotates, and the upper blade plate portion 13a pulls the wire 14. As shown in FIG. 3, the wires 4 and 14 allow the locked portion 6b to be pulled out from the locking portion 5b. In this way, the locked state of the locked parts 6a and 6b, which are means for preventing the shutter from rising, can be released from the locked state by only rotating the lever 4 of the operating part, and at the same time, the sliding door 21 can be barred. It is.

In addition, in the embodiment, the sliding door is opened with the entire slats of the portion that becomes the sliding door connected. However, some of the slats in the portion that becomes the sliding door may be provided so as to be open.

In the locking mechanism in the embodiment, the locked portion biased by a torsion spring is locked in the locking portion. However, the structures of the locking portion and the locked portion are not limited to those described above. The locking mechanism may be an automatic mechanism or a manual mechanism.

There are no particular restrictions on the structure of the interlocking mechanism.

In the embodiment, the sliding door and the interlocking mechanism portions located on the left and right sides thereof were rods having a U-shaped cross section. This shape is effective in that it is lightweight and durable. However, the shapes are not limited to those described above, and any shape may be used as long as it has a strength that allows them to be extruded from each other.

〔Effect of the invention〕

3.2 As described above, the shutter according to the present invention is a shutter in which a plurality of slats are parallel to each other, and the slats are separated so that the slats are sunk into a desired position to form an opening Pm. Locking mechanisms are provided on both sides of the main body so as to be operated by a single operation part via an interlocking mechanism, and when one of the interlocking mechanisms crosses the door, and the locking mechanism is in the locked state, the door and the door are locked. The feature is that the door is temporarily separated at the joint with the shutter body, so when the door is in an open (usable) state, it will not be possible to store it. This eliminates the possibility of storing the bag in an incompletely closed state, resulting in extremely high safety.
