AI Technical Summary
【0016】 請求項1に記載の撓み抑制構造によれば、開閉体よりも見込方向のいずれか他方側に設けられると共に、開閉体の閉鎖方向側に位置する固定対象に固定される第1撓み抑制手段と、開閉体よりも見込方向のいずれか一方側に設けられると共に、固定対象に固定されない第2撓み抑制手段と、第1撓み抑制手段と第2撓み抑制手段とを接続する接続手段と、を備えるので、開閉体に対して見込方向の一方又は他方のいずれから外力が作用した際にも開閉体の撓みを抑制でき、従来技術(補強体をシャッタ板よりも屋内側のみに設ける技術)に比べて、開閉体が開口部に設けられたガイドレールから抜け出すことを回避できる。また、第1撓み抑制手段のみを固定対象に固定するので、嵌合穴を設ける作業に関する手間及びコストを低減でき、撓み抑制構造の設置性を高めることができる。

Abstract
Claims
1. A deflection suppression structure for suppressing the deflection of an opening / closing mechanism that occurs when an external force is applied to the opening / closing mechanism from the direction of projection, in a fully closed state in which the opening of a building is fully closed by an opening / closing mechanism for opening and closing the opening of the building, A first deflection suppression means for suppressing the deflection of the opening / closing body that occurs when an external force is applied to the opening / closing body from either side in the depth direction, the first deflection suppression means is provided on the other side of the opening / closing body in the depth direction and is fixed to a fixed object located on the closing direction side of the opening / closing body, A second deflection suppression means for suppressing the deflection of the opening / closing body that occurs when an external force is applied to the opening / closing body from either the other side in the depth direction, the second deflection suppression means is provided on either side of the opening / closing body in the depth direction and is not fixed to the fixed object, A connecting means for connecting the first deflection suppression means and the second deflection suppression means, A deflection-suppressing structure equipped with [a specific feature].
2. The aforementioned connecting means is A first connecting means connected to the first deflection suppressing means, A second connecting means connected to the second bending suppression means, A third connecting means for connecting the first connecting means and the second connecting means, the third connecting means extending along the surface of the object to be fixed from one side in the depth direction to the other side, The deflection suppression structure according to claim 1.
3. The connection means is configured such that, in the fully closed state, the third connection means is sandwiched between the closing end of the opening / closing body and the object to be fixed. The deflection suppression structure according to claim 2.
4. The connecting means is configured such that, in the fully closed state, the third connecting means is visible from either one side or / or the other side in the direction of view relative to the opening / closing body. The deflection suppression structure according to claim 2 or 3.
5. The first deflection suppression means is placed on the indoor side of the building, The second deflection suppression means is placed on the outdoor side of the building. The first connecting means is detachably connected to the first bending suppressing means, The second connecting means is indestructibly connected to the second bending suppressing means. The deflection suppression structure according to claim 2 or 3.
6. The first bending suppression means is fitted into the fitting hole formed in the fixed object, The first connecting means is housed in the fitting hole. The deflection suppression structure according to claim 2 or 3.
7. The first connecting means is connected to the first deflection suppressing means so as to be movable in the opening and closing direction of the opening / closing body. The deflection suppression structure according to claim 6.
8. The first connecting means includes a fitting portion that is connected to the third connecting means, In the state in which the first deflection suppressing means is fitted into the fitting hole, the fitting portion is fitted into the groove formed between the first deflection suppressing means and the fitting hole, thereby enabling the first connecting means to be detachably connected to the first deflection suppressing means. The deflection suppression structure according to claim 6.
9. In a non-acting state where the external force is not acting on the opening / closing body, the first and second deflection suppressing means are arranged such that they do not come into contact with the opening / closing body, regardless of the opening / closing state of the opening. The deflection suppression structure according to any one of claims 1 to 3.
10. The length of the second deflection suppression means in the depth direction is made longer than the length of the first deflection suppression means in the depth direction. The deflection suppression structure according to any one of claims 1 to 3.
