Description

  The present invention relates to an opening / closing device in which an opening / closing body that slides to open / close is provided with an object sensing means for sensing an object closer to the closing direction than the opening / closing body, and in particular, the opening / closing body is made of a flexible sheet material. The present invention relates to an opening / closing device suitable as a so-called screen shutter device.

Conventionally, this kind of invention has an auxiliary component for the opening / closing body on the lower side of the opening / closing body (opening / closing body main body 10) made of a flexible sheet material, for example, as described in Patent Document 1. Even when the opening (opening 11) is opened and closed by the door (door sheet 30) and the opening / closing body (opening / closing body 10) is closed, the door (door sheet) is used in an emergency or the like. There is a so-called screen shutter device in which 30) is opened to allow passage through the opening (opening 11).
In such a conventional screen shutter device, since the opening / closing body is made of a flexible sheet material that is relatively light and flexible, the opening / closing body during the closing operation should contact the object on the lower side. Even if it comes into contact, the impact on the abutted object can be relatively small.
However, in recent years, it has been demanded to improve the safety of the conventional screen shutter device. In particular, in an opening / closing device having a relatively long width in the width direction of the opening / closing body, the weight of the entire opening / closing body is increased, and the impact when contacting the object is increased. It is preferable to provide means for further reducing the impact when abutting.

Therefore, it is proposed to provide an obstacle sensing device described in Patent Document 2, for example, at the end of the opening and closing body of the conventional screen shutter device in the closing direction.
In the switchgear including the obstacle sensing device as described above, there can be considered a mode in which the sensing signal is wirelessly transmitted to the control unit and a mode in which wired transmission is performed.
In the former mode, there is a risk of malfunction due to, for example, smoke when the infrared system is used, and there is a risk of adverse effects such as noise when the radio system is used.
Therefore, it is preferable to use a mode in which the sensing signal is transmitted by cable as in the latter case. However, in this case, the cable comes into contact with an auxiliary component such as the door, and the opening / closing operation of the opening / closing member is hindered. Ingenuity is required so that there is no.
