Description

Description: TECHNICAL FIELD The present invention is provided in an opening such as a doorway, accommodated in a state of being stacked in parallel with each other, and arranged in the same plane when pulled out along a rail. The present invention relates to a shutter of a type that is arranged to be engaged with a connecting chain.

(Prior Art) Various types of panel shutters have been proposed. Among them, the panel shutter engaged with the connecting chain is stored in a state where the panel shutters are guided in the storage unit guide and stacked in parallel with each other when stored, and when they are pulled out, that is, when the shutter is closed, the panel shutter is guided. Along,
It is developed and arranged in the same plane.

FIG. 4 is a schematic view of the state, and shows a plurality of panel bodies.
41, 42, 43, ... are attached to the connecting chain 48,
When stored in the storage unit guide 47 and pulled out, the connecting chain 48 is pulled out by the sprocket 49, each panel is expanded along the guide rail, and the entrance of the building is closed. In this case, since the storage section is indoors, the left side of the figure is outdoors and the right side is indoors with the expanded panel body as a boundary. In such a panel shutter, a gap is created between each panel body during the opening and closing operation of the shutter, and things and rainwater may enter this gap and pinch a part of the human body, causing a failure or accident. Was there.

In order to prevent such accidents, for example,
As can be seen in Japanese Patent No. 694, there is known a panel body in which a pair of extending portions are provided so as to project from the upper and lower frames. The extending portions of the upper and lower frames of the panel body are shown in FIG. 6 (A).
As shown in, the extension 62 is provided on the indoor side in the lower frame 61, and the extension 64 is provided on the outdoor side in the upper frame 63. As can be seen from FIG. 4, when the panel body is pulled up from the unfolded state and guided to the storage section guide pull 47, the panel body that has moved upward is moved to the right with respect to the succeeding panel body. It That is, the lower frame 61 of the preceding panel body is moved to the right side (indoor side) with respect to the upper frame 63 of the succeeding panel body as shown by the arrow in FIG. 6 (A). Therefore,
In the engagement structure shown in FIG. 5 (B), the lower frame of the preceding panel body cannot move to the right because the upper frame and the lower frame of the panel body are extended as shown in FIG. 6 (A). I had no choice. The same applies when the panel body is pulled out and deployed.
Then, at the time of blockage, it is engaged as shown in FIG. 6 (B), and therefore, during pulling out and blockage,
Rainwater that entered from the outdoor side (left side) through the gap between the panel bodies could not be blocked, and provision of packing 65 was not sufficient, and problems such as rainwater intrusion had not been solved.

(Problems to be Solved by the Invention) The present invention solves the above-mentioned problems, and eliminates the gaps generated in each panel body when the panel shutter is opened and closed, and completely prevents the intrusion of rainwater at the time of blocking. The purpose is to be able to prevent.

(Structure) According to the present invention, a plurality of panel bodies arranged in series in a vertical direction at predetermined intervals on a connecting chain driven by a sprocket are brought into contact with an upper frame of a preceding panel body and a lower frame of a succeeding panel body. In the panel shutter configured to sequentially perform the closing operation, a panel support pin that supports the panel body, one end of which is pivotally attached to the connecting chain at substantially the same interval as the height of the panel body, and the other end of which is the panel. A lever connected to the support pin, a panel pull-up lever that has a rotary shaft at a position eccentric to the rotary shaft of the sprocket and is provided so as to be engageable with the panel support pin,
There is an engaging member that is attached to the sprocket and that engages with the panel pull-up lever, and the panel pull-up lever rotates the panel support pin with a pivot point of the connection chain as a rotation center to rotate the panel support pin near the sprocket. It is characterized in that the panel body is pulled up at a speed higher than the moving speed of the connecting chain. Hereinafter, description will be made based on examples.

1 to 3 are schematic views for explaining one embodiment of the present invention, in which FIG. 1 is a side view, FIG. 2 is a front view, and FIG.
The figure is a perspective view of a main part, and the same reference numerals are shown for the same parts. In the figure, 1 is a connecting chain, 2 is a sprocket, 3 is a panel lifting lever, 4 is a panel body,
5 is a panel mounting bracket, 6 is a panel mounting shaft, 7 is a panel support pin, 8 is a first lever, 9 is a second lever, 10 is a roller, 11 is a connecting shaft, 12 is a long hole, and 13 is a rotation. Pin, 14 is a sprocket shaft, 15 is a sprocket support plate, 16 is an input sprocket, 17 is a panel pull-up lever shaft, 18 is a panel pull-up lever support plate, 19 is a housing guide plate, 20 is a connecting chain holding plate, 21 and 22 are entrance guides. The panel bodies are attached to the connecting chain 1 at the same pitch as the panel pitch, which will be described in detail later. The connecting chain 1 meshes with the sprocket 2 and is pulled up and pulled out. When pulling up or pulling out, the panel pulling lever 3 pulls up the panel body,
The pulling speed acts differently from the speed of the connecting chain, which will also be described later.

The panel body is mounted by pivotally supporting the panel mounting shaft 6 of the panel mounting bracket 5 on the panel support pin 7. The panel support pin 7 has a first
The lever 8 is fixed near one end. A second lever 9 is provided in a symmetrical position across the connecting chain 1, and a roller 10 is supported near one end of the lever 9. A connecting shaft 11 is provided near the other ends of the first and second levers,
Is rotatably supported by the connecting chain 1, but since both levers are fixed by the shaft 11, they rotate integrally.

Next, the operation at the time of pulling up will be described mainly with reference to FIGS. 1 and 2. By rotating the sprocket 2 in the clockwise direction, the connecting chain 1 (not shown) is pulled up, and the panel body is pulled up at the same speed. In synchronization with the pulling up of the connecting chain, the panel pull-up lever 3 rotates clockwise and comes into contact with the panel support pin 7 of the panel body in the vicinity of the guide of the storage section. The panel pulling lever 3 is provided with a long hole 12, and the long hole 12 is engaged with a rotating pin 13 supported by the sprocket 2. The sprocket 2 has a shaft 14 supported by a sprocket support plate 15, and an input sprocket 16
Is driven to rotate. By rotating the sprocket 2,
The rotating pin 13 attached to the sprocket rotates.
The pivot pin 13 engages with the elongated hole 12 of the panel pulling lever 3 to rotate the panel pulling lever 3, but the panel pulling lever 3 is provided with a shaft 17 provided at a position different from the shaft 14 of the sprocket 2. Is pivotally supported by the support plate 18. Since the shaft 17 is located farther than the shaft 14 with respect to the path of the connecting chain 1, when the sprocket 2 rotates at a constant angular velocity, the rotation of the panel pulling lever 3 is changed to the position indicated by the solid line in FIG. At, and slow at the position indicated by the alternate long and short dash line. As a result, the panel support pin 7 that engages with the panel pull-up lever 3 tries to be pulled up faster as the panel pull-up lever 3 rotates, but the speed difference is that the panel support pin is rotated by the first lever 8. It is absorbed by the play by being supported freely. Due to this play, the panel support pin 7 is pulled up while rotating clockwise around the connecting shaft 11, and the panel support pin 7 is pulled up at a speed faster than the speed of the connecting chain. The rotation of the panel support pin 7 about the connecting shaft 11 pulls up the panel body supported by the pin earlier than the succeeding panel body, and the distance between both panels becomes larger than the distance until then, The roller 10 supported by the second lever 9 fixed to the connecting shaft 11 in due course.
Is guided by the guide plate 19 of the storage section. Reference numeral 20 denotes a connecting chain pressing plate which prevents the connecting shaft 11 from moving in the normal direction during the rotation of the first lever. Reference numerals 21 and 22 are guides for the entrance. Explaining with FIG. 5, the lower frame 51 and the upper frame 53 in the unfolded state shown in FIG. 5 (C) lose the slack of the chain due to the driving of the connecting chain, and FIG. 5 (B).
Can be pulled up. When the panel pulling lever is engaged with the panel support pin, the lower frame 51 of the preceding panel is pulled up at a higher speed than the lower frame 53 of the succeeding panel.
The lower frame 51 moves relative to the upper frame 53 in the direction of the arrow in FIG. 5 (B). Therefore, when moving to the right to be stored in the storage section guide 19, the extension section 52 and the extension section 54 are moved.
It never hits.

To pull out the panel from the storage section, reverse the above-described procedure and use the panel pull-up lever 3 to pull out the panel support pin 7.
Is lowered at a faster speed than the connecting chain 1 while rotating counterclockwise about the connecting shaft 11, the speed gradually approaches the moving speed of the connecting chain 1, and is released from the panel lifting lever 3. That is, as shown in FIG. 5 (A), the panel body that moves from the storage section 19 to the entrance section is relatively moved in the direction of the arrow relative to the upper frame of the panel body to which the lower frame of the succeeding panel body precedes. It moves and is deployed in the state of FIG. 5 (B). When the seat plate reaches the bottom, the chain loosens,
It is closed in the state of FIG.

As described above, since the panel body is pulled up or pulled out at a speed faster than the connecting chain 3 at the front position of the guide plate of the storage portion, the lower frame of the panel body and the upper frame of the succeeding panel body at the time of pulling up. Since the gap between the upper and lower frames of the panel body that is pulled down from the storage part when it is pulled down is lowered from the state in which the distance between it and the upper frame of the preceding panel body is large, as shown in Fig. 5, The frame may have a structure having an extension on the outside.

(Effects) As described above, according to the present invention, there is no gap between the panels during the operation of the shutter, and the shape of the lower frame has the extension portion on the outside as shown in FIG. Can be adopted, and it has the effect that a perfect shutter can be obtained even in case of rain.
