Door window

Abstract

A door window that can improve operability and is convenient for ventilation and cleaning are provided. According to the door window, a door window fan (20) can be opened or closed in the depth direction of an opening frame (10). The door window comprises a first opening-and-closing mechanism (40) that has left vertical frame (23) set oppositely when the opening frame closes the door window fan, engaging pins (41, 43) set on one side of the left vertical side frame (13), and engaging parts (42, 44) set on the left vertical frame and the other side of the left vertical side frame and have engaging grooves (42a, 44a) that allow the engaging pins enter and extend aslant relative to the long side direction of the left vertical frame. The door window also comprises a second opening-and-closing mechanism (60) that has a lower frame sliding block (61) and an upper frame sliding block (66) that are set linked to an operation handle (30) in an upper frame (21) and a lower frame (22) and can move in a sliding way along the long side direction of the upper frame and the lower frame. The second opening-and-closing mechanism (60) also has strut parts (62, 67) that are linked to an upper side frame (11), a lower side frame (12) and the door window fan.

Description

technical field [0001] The present invention relates to doors and windows, and more specifically relates to doors and windows such as windows that open in multiple directions as follows: the entire door and window leaf can be moved in the depth direction of the opening frame as, for example, stretching out the window in parallel; The frame that constitutes one side edge of the door and window sash is used as the opening and closing end and moves toward the depth direction of the opening frame. Background technique [0002] As the prior art of doors and windows such as multi-directional opening windows, there is the technology described in Patent Document 1, for example. The door and window has a link part between the opening frame and the door and window sash. The link member has left and right link arms respectively connecting between the upper frame of the opening frame and the upper frame of the door sash, and between the lower frame of the opening frame and the lower fr...

AI Technical Summary

Problems solved by technology

[0006] However, in the door and window proposed in the above-mentioned patent document 1, the door and window leaf is moved relative to the opening frame by adjusting the rotation of the left and right link arms, so it is impossible to make the door and window leaf open and move when the left and right sides of the door and window leaf are opened and moved. The opening relative to the opening frame is large enough to make it difficult to clean the doors and windows

In addition, since the left and right link arms are not linked with each other, the opening and moving mode of the door and window cannot be adjusted by operating a single operating handle, so the operability is not good.
