Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a finger-stuffing prevention structure for a panel shutter that is installed in various openings such as a building, a house, or a garage.

[Problems to be Solved by Prior Art and Invention] Generally, in this type of panel shutter, a leading panel body that is fed in advance and a trailing panel body that is fed out after the leading panel body are provided. Adjacent panel bodies are bound together in a series so that they can be bent freely via hinges.
A shutter curtain is formed.

In this thing, the opening and closing operation of the shutter curtain is
It is formed by being guided by a storage rail that faces the horizontal direction and a vertical rail that faces the vertical direction, but the panel body is bent at the corner formed between both rails, as shown in FIG. 4A. The surfaces of the adjacent panel bodies facing each other on the outdoor side are widely opened to form a gap X. When closing the opening, a finger may be hooked on the gap X to pull down the shutter curtain 1. In this case, the panel body moves to the vertical rail 2 side and the adjacent panel bodies move to each other. There is a risk of finger jamming because the gap X on the outdoor side becomes narrower as the surface becomes flat, and fingers are caught.

Therefore, as shown in FIG. 4B, the upper edge outdoor side portion of the preceding panel body 4 that is advanced in advance is notched, and
Even when the adjacent panel members are flush with each other, the finger Y is prevented from being stuffed by ensuring a gap Y between the facing surface portions of the preceding panel member and the succeeding panel member. The notch for forming cannot be deep enough to reach the indoor side by necessity because the adjacent panel bodies must be in contact with each other at the time of closing, and therefore, in terms of finger stuffing prevention in this back part. There are still problems to be solved.

[Means for Solving the Problem] In view of the above-mentioned circumstances, the present invention was devised with the object of providing a structure for preventing finger jamming of a panel shutter that can eliminate these drawbacks.
Adjacent panel bodies of a preceding panel body that is drawn out in advance in the closing direction and a following panel body that is drawn out after the preceding panel body are foldably connected via a hinge provided on the indoor side In a panel shutter formed by forming a curtain, an indoor-side convex portion and an outdoor-side concave portion are formed in a step shape on a surface portion of the preceding panel body facing the trailing panel body, while the trailing panel body precedes the trailing panel body. On the surface facing the panel body, adjacent panel bodies are flush with each other in the closed posture, and the indoor concave portion facing the indoor convex portion of the preceding panel body and the outdoor concave portion of the preceding panel body are opposed to each other. An outdoor convex portion facing each other with one gap is formed in a step shape, and is adjacent between the indoor convex portion of the preceding panel body and the outdoor convex portion of the following panel body in the panel thickness direction facing each other. To prevent panel members from interfering with each other when folding A second gap is formed, and the pivot position of the hinge is set between the position facing the outdoor concave portion of the preceding panel body and the position facing the outdoor convex portion of the trailing panel body in the closed posture. To do.

Further, according to the present invention, by this structure, the finger stuffing prevention between the opposing portions of the adjacent panel bodies can be surely performed even in the back portion to improve the safety.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings.
In FIG. 1, reference numeral 1 denotes a shutter curtain of a panel shutter, the shutter curtain 1 includes a vertical rail 2 provided in an opening of a building and directed in a vertical direction, and a horizontal direction continuing to an upper portion of the vertical rail 2. It is the same as the conventional one such that it is opened and closed by being guided by the facing storage rail 3.

The shutter curtain 1 is formed by connecting a plurality of panel bodies 4 in series with each other through hinges 5, but the preceding panel body 4 is fed out in advance.
And the trailing panel body 4 which is fed out from the front of the preceding panel body 4 has an uneven step structure between the opposing edges of adjacent panel bodies, and the upper edge of the preceding panel body 4 is formed. The concave portion 4a on the outdoor side formed in is deeply cut out, and when both panel bodies 4 are flush with each other, the concave portion 4a of the preceding (lower side) panel body 4 and the trailing (upper side) opposite thereto ) A first gap Y is formed in the outdoor side half between the panel side body 4 and the outdoor side convex portion 4b so as to prevent finger jamming in that portion.

In addition, between the indoor-side convex portion 4c of the preceding panel body 4 and the outdoor-side convex portion 4b of the following panel body 4 in the panel thickness direction facing each other, the adjacent panel bodies do not interfere with each other when they bend. A second gap Z is formed.

Further, the hinges 5 connecting the panel bodies 4 are arranged on the indoor side, and in this embodiment, the pivot 5a is substantially located at a position facing the outdoor convex portion 4b of the trailing panel body 4. It is installed so that When the adjacent panel bodies 4 become flat, the uneven portion 4 on the indoor side half
The c and 4d are configured so as to be in contact with each other to form a hermetically sealed state, but in the corner portion on the indoor side between the rails 2 and 3, the adjacent panel bodies 4 are bent with the pivot 5a as a fulcrum. In this case, the recess 4d on the indoor side of the trailing panel body 4 is
The indoor-side convex portion 4c is relatively displaced to the indoor side, and the outdoor-side convex portion 4b faces. When the bent panel is brought into the flush state, the trailing panel body 4 swings about the pivot 5a, which is substantially deviated to the position facing the outdoor side convex portion 4b of the trailing panel body 4. Therefore, the front panel body 4 is configured to be shifted and overlapped on the outdoor side. still,
Reference numeral 6 is a guide roller for rolling the rails 2 and 3, and 6a is a roller support shaft thereof.

In the embodiment of the present invention constructed as described above, the opening and closing operation of the shutter curtain 1 is performed by being guided by the vertical rails 2 in the vertical direction and the storage rails 3 in the horizontal direction, and the panels adjacent to each other at this time. The body 4 comrades are bent and guided at the corners.

Therefore, when closing the opening from the outdoor side, even if a finger is caught in the gap between the adjacent panel bodies 4 that are bent and the shutter curtain 1 is pushed down, finger jamming at this time is reliably prevented. Become. So in this one,
At the outdoor side portion, the first gap Y is formed by notching the outdoor side recessed portion 4a of the preceding panel body 4, so that the finger stuffing can be prevented at that portion, but also at the back side, that is, the indoor side. Effective finger stuffing prevention is planned.

That is, when the adjacent panel bodies 4 in the bent state descend and become flush with each other, the trailing panel body 4 is
The pivot 5a that is substantially deviated to the position facing the outdoor side convex portion 4b of the fulcrum will be oscillated so as to shift to the outdoor side,
As a result, it is possible to make the distance between the facing surfaces of the two panel bodies 4 in a bent state narrower without the need to widen them as in the conventional one in which the pivot is at the facing surface position. It will be surely prevented from entering the part. Moreover, since the trailing panel body 4 becomes flush with the leading panel body 4 while swinging toward the outdoor side, the trailing panel body 4 is flush with the leading panel body 4, so that even if a finger is mistakenly inserted into the back gap,
The lower edge of the trailing panel body 4 which is displaced to the outdoor side positively acts to push the entered finger outward, whereby the pinching of the finger is effectively prevented and the safety is enhanced. .

Moreover, in the closed state, the uneven portions 4c and 4d on the upper and lower opposing surfaces of the adjacent panel members are abutted against each other in the indoor half, so that it is considered that the inertial load and the wind pressure at the time of closing are received. The shutter curtain 1 does not work concentratedly on the hinge 5 panel mounting area.
With its high rigidity, it is stable without inadvertent wobbling and has excellent durability.

Incidentally, the present invention is not limited to the above-mentioned embodiment, and the position of the pivot of the hinge is as shown in FIG.
It may be set to L between the position facing the outdoor concave portion of the leading panel body and the position facing the outdoor convex portion of the trailing panel body in the closed posture. Therefore, as in the second embodiment shown in FIG. You may In other words, this is one in which the hinge pivot 5a is set substantially at a position facing the outdoor recess 4a of the preceding panel body 4, and this one also has the same finger jamming prevention function as in the first embodiment. To be demonstrated.

[Effects] In summary, since the present invention is constructed as described above, the hinge shafts of adjacent hinges are connected to each other through hinges arranged on the indoor side so that they can be bent. The position is set between the position where the preceding panel body faces the outdoor concave portion and the position where the trailing panel body faces the outdoor convex portion, so that when the closing operation is performed, the adjacent panel bodies are flush with each other from the bent state. In this state, the trailing panel body swings so as to shift to the outdoor side with respect to the leading panel body.

As a result, the position of the conventional hinge pivot can be made narrower without widening the facing interval between the adjacent panel bodies in the folded state, like the one located at the indoor side corner position of the preceding panel body, It is possible to prevent the finger from entering the back of the facing portion. Moreover, when a finger is mistakenly inserted deeply into this gap, the edge of the trailing panel body that shifts to the outdoor side acts to positively push the finger to the outdoor side, and the finger is caught. Prevent.

Moreover, in the closed state, the upper and lower facing surfaces of the adjacent panel members come into abutting contact with each other in the indoor half,
Even if the inertial load or wind pressure at the time of closing does not act on the hinge's panel body attachment part intensively, it becomes rigid and the shutter curtain is stable without inadvertent wobbling. It is extremely durable.
