Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a connected storm door device for continuously opening and closing storm shutters.

[Problems to be solved by the prior art and the invention] Conventionally, shutters were opened and closed by inserting and removing the shutters one by one. However, the opening/closing work of this type is troublesome and complicated, and therefore, the base end of the operating link, which has a locking protrusion formed at the tip, is attached to the leading shutter that is pulled out from the door bag to the shutter rail in advance. A trailing shutter that is freely installed and pulled out following the leading shutter is provided with a guide rail that moves in the width direction so that the locking protrusion on the leading shutter side is locked to prevent it from coming out, so that the adjacent shutters can It is proposed to connect them in a series.

By the way, in this case, the shutters in a continuous state are simply connected directly via the operating link, so when the leading shutter is pulled and moved, the load is less than the operating load. It will work on all the connecting members including the link board,
As a result, the connecting member must be made of a sturdy material, but in doing so, the shutter itself to which it is attached must also be made to match this, and as a result, the entire shutter is heavy and difficult to operate. The problem is that it becomes .

Furthermore, since storm shutters are most likely to be built outdoors, consideration must be given to closing the rain to prevent rain and wind from blowing in between adjacent shutters. For this reason, conventionally, as shown in Japanese Utility Model Application No. 59-62188, connecting parts that can be engaged with each other are formed on the vertical stile to form a labyrinth structure between adjacent shutters in order to improve the closing of the rain. Are known. However, even in this case, the mating portions are only loosely fitted into each other and are not in an abutting and locking state.

This is because, as shown in FIGS. 7A, B, and C, the tip locking protrusion of the operating link 6 whose base end is pivoted to the leading shutter 1 is attached to the leading shutter side of the guide rail 4 provided on the trailing shutter 1. After reaching the end position, a force is applied to pull out the succeeding shutter 1. Then the subsequent shutters 1
The actuating link 6, which initially protruded outward from the leading shutter 1, is swung to be in a straight line with the guide rail 4, and is pulled out flush. Therefore, at the beginning of the pullout, the operating link 6 swings toward the succeeding shutter, so there is no problem, but toward the end, the operating link 6 moves inward and outward (in the thickness direction of the shutter). As a result, the above-mentioned inclined joining parts 2a, 2b are
Even if it was initially locked,
Due to the final movement of the adjacent shutters in the outward and outward directions, they inevitably become spaced apart from each other in a loosely fitted manner, and as a result, the adjacent shutters are still directly connected by the connecting member including the operating link 6. This poses the problem that the

[Means for Solving the Problems] In view of the above-mentioned circumstances, the present invention has been devised for the purpose of providing a connected shutter device that allows the shutters to be opened and closed continuously, which can eliminate these drawbacks. At the rear end of the leading shutter that is pulled out from the door pocket and onto the shutter rail, a base end of an operating link having a locking roller at its tip is swingably provided, For the succeeding shutter that is pulled out, a guide rail for guiding the movement of the locking roller on the preceding shutter side is provided horizontally in the width direction to connect the adjacent shutters in a series, and also to The frames are abutted against each other on sloped surfaces, and when the door is opened, the trailing shutters that enter the door pocket ahead of each other are pushed into the door pocket in a parallel manner by the guidance of the sloped surfaces from the leading shutter that enters the door pocket later. In the connecting shutter, the opposing vertical frames have mating members that are substantially parallel to the inclined surface and that can be fitted into each other so that the adjacent shutters are flush with each other. On the other hand, at the leading shutter side end of the guide rail, a locking roller located at the leading shutter side end position is retracted and guided closer to the shutter surface side than the end position and toward the leading shutter side. The present invention is characterized in that an auxiliary rail having an inclined guide surface is formed as an extension, and the mating portions are brought into contact and locked together based on the retraction movement of the locking roller to the auxiliary rail.

With this configuration, the present invention enables the connecting portions to abut and lock each other, thereby reducing the load on the operating link.

[Example] Next, an example of the present invention will be described based on the drawings. In the drawing, 1 is a shutter;
Both vertical frames 2 are integrally formed with mating parts 2a and 2b that can be fitted together with those of the adjacent shutters 1,
Further, on the indoor side surface of the shutter 1, a guide rail 4 having upper and lower rail grooves 3 is horizontally installed in the width direction.

5 is a leading shutter 1 that is pulled out in advance from the door pocket 9.
A bracket is formed in a notch of a vertical stile 2, and the base end of an operating link 6 is swingably supported on the bracket 5 by a pin shaft 7.
A roller shaft 8 having a pair of upper and lower rollers 8a is slidably inserted into a long hole 6a bored at the tip of the operating link 6. Trailing shutters 1 pulled out from
is fitted into the rail groove 3 in a freely rolling manner,
In this way, adjacent shutters are connected to each other.

On the other hand, inside the door pocket 9, an inclined guide plate 10,
10a is provided, and the guide plate 10 is connected to the shutter 1.
The guide plate 10a guides the horizontal movement of the shutter 1 when the shutter 1 is pulled out, and the guide plate 10a guides the horizontal movement of the shutter 1 when the shutter 1 is stored, thereby making it easy to take the shutter 1 in and out.

Furthermore, reference numeral 4a is an auxiliary rail, and the auxiliary rail 4a has an operating link 6 at the end of the guide rail 4 on the leading shutter side, which swings toward the indoor side, so that the trailing shutter can be moved indoors.
Based on the fact that the roller 8a is pulled out in an inclined position, the roller 8a located at the end position on the preceding shutter side is extended in an inclined shape in order to guide the roller 8a away from the end position toward the outdoors and toward the preceding shutter side. In other words, roller 8
Based on the retraction movement of the shutter a toward the leading shutter side, the trailing shutter 1 is relatively separated from the leading shutter 1, so that the mating parts 2a and 2b in the fitted state are brought into contact and locked together. It's summery.

In the embodiment of the present invention configured as described above, when closing the shutter 1 (when pulling it out from the door pocket)
When the last stored leading shutter 1 is first pulled out and moved in the axial direction relative to the trailing shutter 1, the roller 8a of the leading shutter 1 moves along the guide rail 4 in response. When the roller 8a of the leading shutter 1 reaches the leading shutter side end of the guide rail 4 and the movement of the roller 8a is restricted, the trailing shutter 1 is pulled by the leading shutter 1. That is,
The trailing shutter 1 moves laterally in an inclined manner toward the exit side of the door pocket along the guide plate 10 as shown in FIG. 5B,
As a result, the mating portions 2a and 2b of both shutters fit together, and the roller 8a is connected to the angle formed by the inclined surface of the auxiliary rail 4a and the actuating plate 6 (the axis of the roller 8a and the pin Until the angle θ between the line connecting the axes of the shaft 7 and the auxiliary rail 4a reaches 90 degrees, a moment acts to swing the operating plate 6 indoors, and the auxiliary rail 4a and Although it is located at the corner with the guide rail 4, when the angle reaches 90 degrees, the moment that tries to swing the actuating plate 6 toward the indoor side disappears, and the angle θ is
If the angle exceeds 90 degrees, a moment will act to swing the actuating plate 6 toward the outdoors, and the roller 8a will be moved from the end position on the leading shutter side to the outdoor side by the auxiliary rail 4a. Since the trailing shutter 1 is moved away from the leading shutter 1, the mating portions 2a and 2b in the fitted state come into contact and lock together, thereby causing the trailing shutter 1 to come into contact with and lock against the leading shutter 1. 1 and the succeeding shutter 1 are connected to each other by abutment and locking of the joining parts 2a and 2b without applying any load to the operating link 6.

On the other hand, when opening the shutter (when storing it in the door pocket), the tip of the shutter 1 pushed into the door pocket 9 hits the forward guide plate 10a inside the door pocket 9 and stops moving. When the shutter 1 is pushed in, the preceding shutter 1 acts in the opposite manner to the case of pulling it out, and moves laterally toward the mirror plate 9a of the door pocket 9. At this time, the joining parts 2a and 2b of each vertical stile 2 are disengaged,
The roller 8a moves from the auxiliary rail section 4a to the guide rail 4, and when the trailing shutter 1 is further pushed into the door pocket 9, the roller 8a moves along the guide rail 4, and in this way, the trailing shutter 1 is pushed into the door pocket 9. The shutter 1 and the succeeding shutter 1 are stored in parallel, and by repeating this operation in sequence, all the shutters are stored in the door pocket 9 in parallel.

As described above, in the present invention, although the vertical stile 2 has the mating parts 2a and 2b that can be mutually fitted with the adjacent shutter 1, when the shutter 1 is opened and closed, the action of the auxiliary rail 4a is As a result, the mating portions 2a and 2b in the fitted state come into contact and lock with each other based on the relative separation of the succeeding shutter 1 from the preceding shutter 1. Therefore, the load during movement of the shutter 1 is borne by the abutment and locking of the mating parts 2a and 2b, and as a result, the connection of the auxiliary rail part 4a, the operating link 6, the roller 8a, etc. This may be because it eliminates the inconvenience of having to make the components from particularly strong materials, and it also eliminates the need for reinforcement of the shutter itself, which in turn makes it possible to significantly reduce the weight of the shutter and improve operability. can be significantly improved. Furthermore, this joining part 2a, 2
b, the roller 8a is connected to the auxiliary rail portion 4a.
This is done automatically by being guided by the inclined lateral movement of the shutter 1 as it rolls, so there is no hindrance to the opening and closing of the shutter, and it is extremely easy to do. convenient.

[Operations and Effects] In summary, the present invention is constructed as described above, and the base of the operating link, which is provided with a locking roller at the tip, is attached to the leading shutter that is pulled out from the door bag to the shutter rail in advance. The end is swingable,
A guide rail that guides the movement of the locking roller on the preceding shutter side is provided horizontally in the width direction of the trailing shutter that is pulled out following the leading shutter, so that the adjacent shutters are connected in a series, and the vertical frame of the shutter is The leading shutter of the guide rail that guides the locking roller provided at the tip of the operating link is formed at the portion of the shutter so that the adjacent shutters can fit into each other in a state where they are flush with each other. At the side end, the operating link swings toward the back side of the shutter and pulls out the succeeding shutter in an inclined position, so that the locking roller located at the leading shutter side end position is moved closer to the shutter surface than the end position. An auxiliary rail is formed to extend on the side and has a guide surface for guiding the evacuation toward the leading shutter side. That is, based on the retraction movement of the locking roller toward the preceding shutter side, the succeeding shutter can be relatively separated from the preceding shutter, and the mating parts in the fitted state can be brought into contact and locked.

Therefore, the moving load when operating the shutter is borne by the abutment and locking of the mating portion, and it is possible to prevent a large load from being applied to the operating link. As a result, it is possible to eliminate the inconvenience of having to make the connecting member from a particularly strong material, and the accompanying reinforcement of the shutter itself is also unnecessary, which in turn makes it possible to significantly reduce the weight of the shutter. This can greatly improve operability.
