Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to fittings such as doors, windows and shoji screens.

[Conventional technology]

Conventionally, in the fittings as described above, it is known that a part of the fittings is opened at the time of closing so as to have air permeability inside and outside the room, and as such fittings, the upper part of the fittings is moved from the fitting frame to the outdoor side. Some of them have been made to project to be in a ventilated state and then brought into contact with a fitting frame to block ventilation.

[Problems to be solved by the device]

However, in the conventional fitting constructed as described above, only one upper part of the fitting can be ventilated, so that there is a problem that sufficient ventilation cannot be obtained depending on the structure and condition of the room in which the fitting is provided. there were.

The present invention solves the above-mentioned problems and allows the indoor and outdoor to communicate with each other at two places, the upper and lower places, and a sufficient ventilation amount can be provided regardless of the structure and state of the room in which fittings are provided. The object is to provide a fitting that can be obtained with good operability with a relatively simple structure.

[Means for Solving the Problems]

In the fitting of the present invention, a lower member that abuts the lower frame of the fitting frame when descending and is separated from the lower frame when ascending is slidably fitted in the inner periphery of the fitting frame and has an intermediate portion in the vertical direction. Fits the upper member that bends in one of the indoor and outdoor directions of the joiner frame so that it can be bent and stretched, and partitions the interior and exterior of the room with both upper and lower members.
The upper edge and the lower edge of the upper member are connected to the upper edge of the joiner frame and the upper edge of the lower member respectively so as to be bendable in one of the indoor and outdoor directions of the joiner frame, and the lower member is attached to the inside of the lower member. A holding member is provided to hold the fitting frame at a plurality of positions in the vertical direction.

[Action]

In the fitting according to the present invention, the lower member rises in a state in which the vertical middle portion of the upper member is bent in one of the indoor and outdoor directions, and the inside and outside of the room in which the fitting is provided communicate with each other at two upper and lower locations. However, a sufficient amount of ventilation can be obtained. Moreover, not only can ventilation be satisfactorily performed from the gaps on both sides of the upper member that is bent in two, but the bending point can be opened with a slight narrow width, so the part that is the line of sight is a very small opening However, there is no danger of being peeped into the room from the outside or being easily exposed from the outside. Further, when the upper member is extended, the lower member descends, communication between the inside and outside of the chamber is blocked, and by performing one of the bending operation of the upper member and the lifting operation of the lower member, the upper and lower members are interlocked. As a result, the above-mentioned communication and communication cutoff switching operations can be performed, and operability is good. Furthermore, by holding the lower member to the fitting frame by the holding member, both the upper and lower members are kept in the communication and communication cutoff states. Yes, it is not necessary to separately hold the upper and lower members, and the mechanism for interlocking, operating and holding both the upper and lower members is relatively simple.
The opening can be easily adjusted during communication.
