[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inward window for opening a space between an upper portion of a window frame and an upper portion of the sash window to ventilate the window frame by tilting the sash with respect to the window frame toward the indoor side.

[0002]

2. Description of the Related Art An inward window generally known in the prior art is as follows. The lower frame forming the window frame and the lower frame forming the shoji are hingedly connected to the interior and exterior directions by a hinge, and one end of the arm is connected to the vertical frame forming the window frame so as to be swingable in the interior and exterior directions. In addition, a slider is slidably provided along a vertical frame forming a shoji, and the slider and the other end of the arm are swingably connected in the indoor and outdoor directions, and are slid on the vertical frame. Depressed window with a mover stopper.

When the sliding door is tilted to the indoor side, the sliding door slides downward along the vertical frame, and the sliding door contacts the stopper to tilt the sliding door to the indoor side. To hold.

In the above-mentioned window, the angle of the sliding door toward the room is restricted by the arm, the slider and the stopper. If the falling angle of the sash is large, the impact force when the slider comes into contact with the stopper increases, so the falling angle of the sash is reduced to reduce the impact force. However, if the falling angle of the shoji is small, the size of the opening formed between the upper frame of the window frame and the upper frame of the shoji is small, and it is necessary to put a hand or the like through the opening to clean the outdoor surface of the shoji. Hard to do.

[0005] In order to solve this problem, there have been proposed various inward windows in which the inclination angle of the shoji can be adjusted in two steps so that the inclination angle can be reduced during normal operation and increased during cleaning. For example, utility model registration 2
An inward window disclosed in Japanese Patent No. 533301 has been proposed.

In the above-mentioned window, a long slide guide is attached to the vertical frame of the shoji, a pin-shaped slider is attached to the other end of the arm, and the slider is slid along the long groove of the long slide guide. Move freely. A cover is attached to the vertical frame of the shoji, and a stop lever is swingably mounted in this cover between a stop position crossing the long groove and a stop release position away from the long groove, and a stopper lever is provided by an operation knob provided outside the cover. Is a shape that swings.

[0007] According to the above-mentioned inward falling window, by setting the stop lever to the stop position, the slider comes into contact with the stop lever, and the falling angle of the shoji becomes small. When the stopper lever is set to the stop release position, the slider slides to the lower end of the long groove, so that the falling angle of the shoji increases.

[0008]

The tilting angle of the shoji can be adjusted in two stages by swinging the stop lever with the operation knob of the above-mentioned inward tilting window. However, when the interior window is viewed from the room, the operation knob is only visible to the side of the cover and is not noticeable, and since the operation knob is rotated to adjust the falling angle of the shoji, the first time you do not know the adjustment operation It is difficult for a person to adjust the falling angle of a shoji.
