Description

  The present invention relates to an opening / closing device provided in an opening of a structure such as a house window.

  In order to prevent wind and rain and fire, and to improve crime prevention, shutter curtains, which are opening and closing devices, are often attached to entrances and exits of structures such as buildings. The shutter curtain is normally fully opened for daylighting and ventilation in the daytime. At this time, when the shutter curtain is fully opened, a blind, a roll screen, or the like is provided in the opening in order to block the line of sight and solar radiation from the outside.

  However, when the roll screen is pulled down in parallel with the shutter curtain, the depth of the storage case for storing them becomes large, the appearance is lowered, and the repair and replacement thereof become complicated. As a solution to such a problem, there is a shutter disclosed in Patent Document 1 below.

The shutter is provided with a box-shaped case that is grounded along the lower end of the shutter curtain when the shutter curtain is fully closed, and a roll roll-up screen, so-called roll screen, is provided in the case. According to this shutter, when the shutter curtain was half-opened or fully opened, the screen was pulled down from inside the box case that was raised together with the shutter curtain, and the external line of sight and solar radiation could be blocked.

Further, it is not necessary to arrange the roll screen unit 31 in the housing case 17 of the shutter curtain 15. The feeding end 43 of the screen 45 can be locked and fixed to the tip member 73. Further, when the shutter is closed, the shutter curtain 15 can be unlocked or the screen 45 can be unlocked. In other words, the distal end member 73 and the proximal end member 75 are connected to each other by the end member connecting means 77. The state can be selected between the state and the state in which the screens 45 are separated from each other. For example, when the screen 45 is only unlocked, that is, the connection between the distal end member 73 and the proximal end member 75 is performed, and the shutter curtain 15 is opened, The screen 45 fixed to the distal end member 73 is fed out as the roll screen unit 31 provided on the proximal end member 75 is raised.

Since the screen can be shared by the existing locking projection for the shutter curtain, it is easy to mount the roll screen unit without adding new locking means.
Furthermore, when the shutter is closed, the shutter curtain can be unlocked and / or the screen can be unlocked at the same time. For example, when the shutter curtain is unlocked and the shutter curtain is opened, the feeding end becomes a locking projection. The screen that is locked to is fed out along with the winding of the shutter curtain. Thus, unlike the conventional method, it is possible to improve the operability by eliminating the need for twice the operation of extending the screen after the shutter is fully opened.

  According to the opening and closing apparatus of the second aspect, the end member is divided into the tip member and the base end member in the extending manner, the lock means is provided on the tip member, and the roll screen unit containing the screen is provided on the base end member. Since the screen feeding end of the roll screen unit is fixed to the tip member, and the end member connecting means is provided that can connect / disconnect the base end member and the tip member across the base end member and the tip member. The roll screen unit can be easily retrofitted simply by replacing the existing end member and the end member with the screen unit. In addition, since it is not necessary to arrange a roll screen unit in the shutter curtain housing case, the size of the opening / closing device in the depth direction can be reduced. And since the extending | stretching end of a screen can be latched and fixed to a front-end | tip member, attachment of a roll screen unit becomes easy, without adding a new latching means. The tip member may have both a function of locking the shutter curtain locking means to the locking projection and a function of locking the feeding end of the screen to the locking projection. Furthermore, unlike the prior art, it is possible to improve the operability by eliminating the need to double the screen after the shutter is fully opened.
