Door and window

Abstract

The present invention relates to doors and windows. The opening of door and window leaves with respective to opening frames is adequately large while excellent ventilation performance is maintained. The door and window is provided with an opening frame formed by installing frame components at an opening edge part of a body, and door and window leaves moving to open and close in relative to the opening frame, and the door and window leaves move to open and close in a depth direction of the opening frame and between an opening-sealed sealing position formed by the opening frame and a ventilation position from which the leaves move along the depth direction of the opening frame, and move to open and close along the surface of the body and between the ventilation position to an open position from which the leaves move along the surface of the body. A right vertical frame composing the opening frame is provided with a fixed frame part installed at the opening edge part and forming the opening; and a movable frame part which is connected with the door and window through a connection part. The door and window leaves are arranged opposed to the fixed frame part under the condition of moving to open and close between the sealing position and the ventilation position so as to allow movements of the door and window leaves, and move to open and close altogether under the condition of moving between the ventilation position and the open position.

Description

technical field [0001] The present invention relates to a door and window, and more specifically, to a door and window in which the entire door and window sash is opened and closed in the depth direction of an opening frame, such as a parallel push-out window. Background technique [0002] For example, the technique described in patent document 1 is provided as the conventional technique of the door window like a parallel push-out window. The door / window includes a link member between the opening frame and the door / window sash. The link member includes left and right link arms respectively connecting between the upper frame member of the aperture frame and the upper frame member of the door sash, and between the lower frame member of the aperture frame and the lower frame member. One end of these link arms is connected by a rotating shaft, and the other end is slidably connected. [0003] In such a door and window, by rotating all the link arms along the depth direction of...

Problems solved by technology

[0005] However, in the doors and windows proposed in Patent Document 1, since the doors and windows are opened and moved relative to the opening frame by adjusting the rotation of the left and right link arms, when the left and right sides of the doors and windows are opened and moved, the doors and windows are relatively Since the opening of the opening frame is not sufficiently large
