The opening / closing body according to the present embodiment is disposed in or inside an opening or inside of a housing such as a house, building, warehouse, factory, underground mall, tunnel, vehicle loading platform, etc. An example of a so-called shutter device that partitions or opens the space will be described.

  The opening / closing body 1 includes a plurality of slats 10 extending in the width direction of the opening / closing body in the opening / closing direction. A curled engaging portion 11 is provided on the lower side in FIG. 1, and a curled engaged portion 12 is provided on the other slat 10 on the one slat 10 side (upper side in FIG. 1). The joining portion 11 and the engaged portion 12 are wound so that the other portion rotates with respect to one (see FIG. 1).

  The opening / closing body 1 is guided up and down by guide rails (not shown) surrounding both ends in the width direction, and is opened and closed by being wound or unwound by a winding shaft (not shown). To do.

  Each slat 10 is formed by bending a substantially rectangular metal plate that is elongated in the opening / closing body width direction, and has a front side 11 that is substantially horizontally long when viewed from the front, and one end side in the opening / closing direction of the front side 11 (see FIG. The protruding portion 12 and the engaging portion 13 which are bent at the lower end side according to the example shown, and the overlapping portion 14 which is bent at the other end side in the opening / closing direction (the upper end side according to the illustrated example) of the front face portion 11. And the engaged portion 15 (see FIG. 2).

The projecting portion 12 is a portion continuously provided on the lower end side of the front surface portion 11 and projecting downward from the engaging portion 13 described later. According to the illustrated preferred example, the projecting portion 12 has a substantially V-shaped cross section, The part which overlaps with the superposition | polymerization part 14 mentioned later is curving.
An engaging portion 13 is connected to the end portion of the protruding portion 12 opposite to the front surface portion 11.

The overlapping portion 14 is connected to the upper end side of the front surface portion 11, and is a portion formed so as to be close to or in contact with the protruding portion 12 so as to overlap, and is curved along the protruding portion 12. Is formed.
An engaged portion 15 is connected to the end portion of the overlapping portion 14 opposite to the front surface portion 11.

Each of the engaging portion 13 and the engaged portion 15 has a shape in which an end edge side is wound in a substantially curled longitudinal section, and is engaged with each other so that the other rotates.
The amount of engagement of the engaging portion 13 and the engaged portion 15 is 5 with respect to virtual planes f1 and f2 (see FIG. 3) in which two slats 10 and 10 adjacent in the opening and closing direction are substantially orthogonal to the opening and closing body opening and closing direction. It is set appropriately so as to intersect within the range of -12 times (5 times according to the illustrated example).

  The engaging portion 13 and the engaged portion 15 have a maximum dimension x1 in the opening / closing body thickness direction in the engaged state of 40 to 100% of the maximum dimension x2 in the opening / closing body thickness direction of the slat 10. It is set so as to be within the range (in the illustrated example, about 43%) (see FIG. 2).

Further, the engaged portion 13 and the engaged portion 15 in the engaged state are arranged at a predetermined interval x in the opening / closing body thickness direction with respect to the front surface portion 11 constituting the front side of the opening / closing body 1 ( (See FIG. 3).
More specifically, the most front portion 11 side (in other words, the front side of the opening and closing device 1 in the illustrated example) of the engaged portion 13 and the engaged portion 15 in the engaged state is located on the front portion 11. They are arranged at a predetermined interval x in the opening / closing body thickness direction.
The predetermined interval x can effectively prevent the engagement portion between the engaging portion 13 and the engaged portion 15 from being cut by a hook-shaped tool or the like, and the opening / closing body 1 is not shown. The winding diameter is appropriately set so as not to be excessive when wound on the winding shaft.

Next, the effect of the opening / closing body 1 of the illustrated example will be described in detail.
When trying to break off the opening and closing member opening direction by experimentally the opening and closing member 1 scissors tool p, cutting path q scissor-like tool p, as shown in FIG. 4 (a), the engaging portion 13 and Hikakari In the vicinity of the engagement portion of the joint portion 15, the path is curved toward the back side of the opening / closing body 1 (left side in FIG. 4).

First, in the superposition location of the protrusion part 12 and the superposition | polymerization part 14, the upper and lower slats 10 and 10 cross | intersect 3 times with respect to the virtual plane e substantially orthogonal to the superposition | polymerization surface.
Therefore, when trying to cut this overlapping portion with the hook-shaped tool p, the cutting resistance is greater than when cutting the front surface portion 11 of the slat 10.
This cutting resistance is also increased by the fact that the overlapping portion of the protruding portion 12 and the overlapping portion 14 is curved, or the protruding portion 12 is substantially V-shaped having an internal space.

Further, at the engagement portion between the engaging portion 13 and the engaged portion 15, the upper and lower slats 10, 10 intersect the virtual planes f1, f2 substantially orthogonal to the opening / closing body opening / closing direction five times.
Therefore, when it is going to cut | disconnect this engagement location with the hook-shaped tool p in the opening-and-closing body opening direction, compared with the conventional opening-and-closing body 100 illustrated in FIG.4 (b), the cutting resistance is large.
In other words, according to the conventional opening / closing body 100, the engagement points of the upper and lower slats 110, 110 intersect only four times with the virtual plane f0 substantially orthogonal to the opening / closing body opening / closing direction. However, in the opening / closing body 1 of the present embodiment, the number of intersections is increased by increasing the amount of engagement of the engaging portion 13 and the engaged portion 15 and providing the protruding portion 12. Cutting resistance is greater than 100.

  In addition, although the above demonstrates the effect when the opening / closing body 1 is cut | disconnected in the opening direction (upward in FIG. 4), when the opening / closing body 1 is cut | disconnected in the closing direction (downward in FIG. 4) Also, substantially the same effect can be obtained.

  Further, according to the illustrated opening / closing body 1, the engaging portion 13 and the engaged portion 15 intersect four times with respect to virtual planes f1 and f2 substantially orthogonal to the opening / closing body opening / closing direction, and the front surface portion 11 is 1 Although it was set as the structure which cross | intersects and crosses 5 times in total, it is also possible to set it as the aspect which only the engaging part 13 and the to-be-engaged part 15 cross within the range of 5-12 times.

  Next, another example of the opening / closing body according to the present invention will be described. In addition, in the opening / closing body shown below, about the location which is substantially the same as the said opening / closing body 1, the detailed description which overlaps by omitting the same code | symbol as the opening / closing body 1 is abbreviate | omitted.

The opening / closing body 2 shown in FIG. 5 has an engaging portion 13 and an engaged portion 15 (more specifically, the forefront portion of the engaging portion 13 and the engaged portion 15 in the engaged state) with respect to the opening / closing body 1. 11) and the front face 11 is set more appropriately.
The interval x3 is within a range of 1.5 to 3 times the maximum dimension x4 in the opening / closing body thickness direction at the engagement position of two slats 10 ', 10' adjacent in the opening / closing direction (in the illustrated example, about 1.. 7 times).
According to the opening / closing body 2, when the cutting tool is intended to cut in the opening / closing body opening / closing direction, the opening angle of the hook-shaped tool becomes relatively large. Therefore, it becomes difficult to perform the cutting operation, and as a result, it is possible to more effectively prevent the opening / closing body 2 from being broken by a malicious third party.

Further, the opening / closing body 3 shown in FIG. 6 is configured by alternately arranging two types of slats 20 and 30 in the opening / closing body opening / closing direction.
One slat 20 is formed by bending a substantially rectangular metal plate that is long in the width direction of the opening and closing body, and has a front side 21 that is substantially horizontally long when viewed from the front, and both end sides of the front side 21 in the opening and closing direction ( According to the illustrated example, two projecting portions 22 and 23 formed by bending on the upper and lower end sides)
It consists of a curled engaging portion 24 formed on the end edge side of one projecting portion 22 and a curled engaged portion 25 formed on the end edge side of the other projecting portion 23.
That is, the slat 20 has two protrusions 22 and 23 on both sides of the opening / closing body opening / closing direction, whereas the slat 10 of the opening / closing body 1 has the protrusion 12 only on one side in the opening / closing body opening / closing direction. It is arranged.
An engaging portion 24 having substantially the same shape as the engaging portion 13 of the opening / closing body 1 is provided on the end edge side of the one protruding portion 22, and the engaged portion of the opening / closing body 1 is provided on the end edge side of the other protruding portion 23. An engaged portion 25 having substantially the same shape as the joint portion 15 is provided.

The other slat 30 is formed by bending a substantially rectangular metal plate that is long in the width direction of the opening and closing body, and includes a front portion 31 that is substantially horizontally long when viewed from the front, and both ends of the front portion 31 in the opening and closing direction. Two overlapping portions 32, 33 formed on the side (upper and lower ends in the illustrated example), a curled engagement portion 34 formed on the edge side of one overlapping portion 32, and the other overlapping portion And a curled engaged portion 35 formed on the edge side of 33.
That is, the slat 20 has two overlapping portions 32 and 33 on both sides in the opening / closing body opening / closing direction, whereas the slat 10 of the opening / closing body 1 has the overlapping portion 14 only on one side in the opening / closing body opening / closing direction. It is arranged.
An engagement portion 34 having substantially the same shape as the engagement portion 13 of the opening / closing body 1 is provided on the edge side of one overlapping portion 32, and the engagement portion of the opening / closing body 1 is provided on the end edge side of the other overlapping portion 33. An engaged portion 35 having substantially the same shape as the joint portion 15 is provided.
