Description

[Detailed description of the invention] 〔Technical field〕 The present invention relates to a shutter having a sliding door.

[Background technology]

Conventionally, when people entered or left the building with the shutter fully down, the only inconvenient method was to hold the shutter each time and sneak through. In addition, if you want to go out, there is the inconvenience of having to take down the fallen vine 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. This invention has improved the above-mentioned inconvenience.

However, this shutter is extremely dangerous if the cover opens during storage or descent, so it has been a challenge to develop a mechanism to prevent this from occurring.

[Purpose of the invention]

Therefore, an object of the present invention is to provide a shutter with a sliding door that does not open during the vertical movement of the shutter.

[Disclosure of the invention]

The inventor has completed this invention after extensive studies to achieve the above object.

In this invention, a plurality of slats are parallel to each other, and the slats are separated so that an opening for the furnace can be formed at a desired position, and the slats in the part that will become the sliding door can be released from the slats in the shutter body. The shutter has an opening member that is horizontally connected to the shutter, and a holding member that maintains the opening member in a barred state is provided on the slat on the shutter body side, and the shutter is fully closed. The gist of the shutter is that the holding member is released from being held by the opening member when the holding member is opened.

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
Slab l-1 is formed so that an opening 11 is formed at the position where
, 1, 1 are separated. In the figure, la, lb, and lc are the slats that form the sliding door. A handle 3 is provided on the sliding door 2. At the back of the handle 3, a bar 5 extending upward and a bar 6 extending downward are pivotally attached at one end to a peripheral edge 4 of an axis serving as a center of rotation. As shown in FIG. 4, the upward rod 5 and the downward rod 6 each have a single-shape cross section, and the other ends of each are planar. The other ends of the upward rod 5 and the downward rod 6 face the tips of the downward rod 7 and the cross-shaped rod 10, respectively, which have the same U-shaped cross section. These tips are also planar. The downward rod 7 has its upper end pivotally connected to one end of a pivot body 8 having a boomerang-shaped plate. Similarly, the upward bar 10 is pivoted at its lower end to one end of a pivot body 11 having a boomerang-shaped ramp. The other end of the pivot body 8.11 extends from the slabs 1-1a and 1c of the part that will become the sliding door 2 to the slat 1 of the shutter body.
．． 1 and a horizontal bar 9, 1 which is an opening member that is releasably connected laterally to
It is pivotally connected to each other end of 2. These horizontal bars 9, 12 have a U-shaped cross section. An extension piece 13 extends diagonally downward from the shaft peripheral edge 4 of the handle 3. One end of a horizontal bar 14 having a U-shaped cross section and serving as an opening member like the horizontal bars 9 and 12 is pivotally attached to the tip of the extending piece 13.

The other end of the horizontal bar 14 is engaged with a bar 15, which is a holding member that maintains the barbed state, as shown by the chain line in FIG. This rod 15 has a U-shaped cross section, and is placed on a long rod 16 that also has a U-shaped cross section. As shown in FIG. 2 and FIG.
When the long bar 16 is pressed against the ground, the elongated bar 16 rises, and as a result of this pushing up, the bar body 15 rises to release the locking of the horizontal bar 14.

The abutting ends of the rod 15 and the elongated rod 16 also have a planar shape, but are hidden and not shown in the figure. In the figure, 22

a, 23 a and rod 15. It is attached between each of the long rods 16. 15a and 16a are guide parts. In addition,
FIGS. 2 and 4 show the internal structure near the submerged door as seen from the outside. As shown in these figures, the upward rod 10 pivoted to one end of the pivoting body 11 located below the sliding door 2 is connected to one end of the fixed spring 21, and the upward rod 10 is connected to one end of the fixed spring 21, and the upward bar 10 is pivoted in the direction of the shaft peripheral edge 4. I am receiving a force that pulls me towards. The fixed spring 21 is fixed to the guide portion 10a of the upward bar 10. In the figure, 12a and 12b are guide parts that guide the horizontal bar 12 for opening. A notch groove 18 is provided near the tip of the upper surface of the opening horizontal bar 14 near the shaft peripheral edge 4, and a recess 19 is provided near the shaft peripheral edge 4. The cutout groove 18 is a portion that engages with the protrusion 24 at the upper end of the rod 15. The fourth part 19 is the guide part 14 of the horizontal bar 14.
This is the part into which the protrusion near the tip a of the spring piece 14b attached to a is inserted. This serves as an auxiliary lock when the crossbar 14 is in the barred state. As shown in Figure 5, the pivot mount 8 above the sliding door 2
The downward rod 7 pivotally attached to one end is connected to one end of the fixed spring 20, and is always subjected to the force of being pulled in the direction of the shaft peripheral edge 4. The fixed spring 20 is fixed to the guide portion 7a of the downward bar 7. In the figure, 5a is an upward bar 5
The guide portions 9a and 9b are the guide portions of the horizontal bar 9 for opening.

As shown in FIGS. 2 and 5, notches 29 are provided near the tips of the upward rod 10 and the downward rod 7. As shown in FIGS. As can be clearly seen from FIG. 6, each notch 29 is a portion for receiving a pin 31 at the tip of a cam 30 fixedly and pivotally connected to the slat 1a or 1c. Furthermore, the pin 3
1 vicinity is pulled by a fixed 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. 6) of the notch 29 when the horizontal bar 9 or 12 is in a barring state.

This prevents the pin 31 from moving with a small amount of force, so the downward bar 7. - The L-oriented rod 1° is prevented from protruding toward the adjacent slat 1b as the slat is bent when the slat is stored.Next, the operation of the above embodiment will be explained.

As shown in Figures 2 to 4, when the shutter is lowered, the downward bolt 28 is pressed against the long rod 16, causing the rod 15 to rise and return to its locked state. The holding of the open state by the horizontal bar 14 is released.

In this way, the hidden door 2, which was held open by the rod 15 to prevent danger and could not be opened while the shutter was lowering, becomes openable. In order to open the hidden door 2, it is sufficient to simply rotate the handle 3 shown in FIG. 1 in the clockwise direction (in the direction of the arrow). As a result of this rotation, the upward rod 5 and the downward rod 6, which are pivotally connected to the shaft peripheral portion 4 of the handle 3, retreat toward the handle, as shown in FIG. 2 or 5, respectively. As a result, the downward rod 7 and the upward rod 10, which had been pushed into the upward rod 5 and the downward rod 6, respectively, are released from their respective springs 2.
Due to the restoring force of 0.21, it extends toward the handle, and the sliding door 2
Install bolts between the inner slats. According to the movement of the downward bar 7 and the upward bar 10, the barred horizontal bar 9,12 moves back into the door 2 and unbars. Further, as shown in FIG. 1, the extending piece 13 extending from the shaft peripheral edge 4 rotates as the handle 3 rotates. Along with this, the horizontal bar 14 was also unbarred and the submerged door 2 was opened.
retreat inside. In this way, the bolt between the sliding door 2 and the shutter body is removed and the shutter is in an open state. To close the door 2, the handle 3 may be rotated in the opposite direction. The horizontal bars 9, 14, 12 respectively bar the lateral shutter body side slats 1 and release the vertical bar in the sliding door 2.

When the shutter starts to rise when it is retracted,
As shown in FIG.
The long rod 16 and the rod body 15 descend due to the restoring force of 2. As a result, as shown by the chain line in FIG. 4, the protrusion 24 at the upper end of the bar 15 enters the notch N618 on the upper surface of the horizontal bar 14, and the horizontal bar 14 is held in the barred state. If the movement of the horizontal bar 14 is stopped, the handle 3 (first
(shown in the figure) also remains stuck in a vertically downward position. Therefore, as shown in FIG. 1, the horizontal bars 9 and 12 can also be stopped in their respective bolted states. By fixing the handle 3, there is no fear that the door 2 will open while the shutter is being retracted.

In the embodiment, the mechanism for maintaining the open state of the barred horizontal bar is such that the protrusion at the upper end of the bar enters the notch groove provided on the top surface of the horizontal bar. It was to be locked. However, the shape and holding method of the holding member that maintains the open state are not limited to the embodiments.

In the embodiment, the protrusion retractably protruding from the lower end of the shutter body was a bolt. As shown in Figure 3, this bolt 28 can be tightened by the nuts 34 and 35 by adjusting its position, so even if the elasticity of the springs 22 and 23 changes, it can be adjusted accordingly. can be done. However, the protrusion may not have an adjustment function like the bolt described above. In addition, in the embodiment, the rod body 15 and the long rod 1
The spring bias was applied to both of the parts 6 and 6. however,
The spring bias is applied only to the rod serving as the holding member, and the long bar having a retractable protrusion at its lower end is provided with a function to prevent the shutter from falling downward. It doesn't matter if you don't have one.

In addition, in the embodiment, the sliding door is opened with all the slats of the sliding door part continuous, but it may be provided so that some of the slats forming the sliding door are opened. do not have.
