Description

[Detailed Description of the Invention] This invention relates to an improvement in an opening/closing window in which a plurality of vanes arranged vertically in parallel between opposing window frames are rotated by an interlocking mechanism to open and close the window.

Conventionally, in this type of opening/closing window, the center of rotation of the slats was placed at the midpoint of both end faces in the longitudinal direction of each slat, and in order to improve airtightness and watertightness when the window was closed, In many cases, a structure is adopted in which a tight material is provided along the length of each opposing surface and the tight material is pressed against the side end surface of each vane.

However, in such a conventional structure, the end face of the slat is always in sliding contact with the tight material while the window is opened and closed, creating resistance when rotating the slat and requiring a large rotational force. The direction of the sliding contact force that the tight material receives from the end surface of the vane is reversed every time the window is opened or closed, so the tight material is required to have great durability. There were drawbacks such as concerns about ensuring airtightness and watertightness because there were parts where the direction of the dynamic pressure welding force was opposite. Furthermore, in the case of an opening/closing window that is closed with the slats tilted, it is necessary to increase the width of the tight material by the amount of the slant, which has the disadvantage of further increasing the rotational force of the slats.

This idea was made in order to eliminate the above-mentioned drawbacks of the conventional method.It is an opening/closing window in which the slats are closed in an inclined state, and there is no sliding contact with the tight material when opening and closing the window. It does not require a large rotational force, and because the force is applied to the tight material in one direction as a whole and there is no point where the direction of the force is reversed as in conventional methods, it is possible to eliminate early damage to the tight material. The object of the present invention is to provide an opening/closing window that can simultaneously ensure stable airtightness and watertightness.

This idea opens and closes a window by rotating a plurality of vertically arranged slats via an interlocking mechanism interposed between the slats and the vertical frame, and also opens and closes the window by rotating the lower part of the slats. In an opening/closing window that is closed with each vane overlapping the upper part of the outdoor side of the vane and tilting downward toward the outdoor side, a vane holder is provided at both ends in the longitudinal direction of the vane, and the vane holder is connected to the A pivot connection part to the interlocking mechanism, a contact part to the outdoor-facing tight member provided on the vertical frame, and an upper part of the slat holder that is continuous with and adjacent to the lower side of the contact part to the tight member. and a stepped part accommodated between the slats and the tight material, and the contact portion of each slat holder contacts the tight material in a substantially continuous state in a closed state of the slats tilted downward toward the outdoor side. There is.

A round rod-shaped pivot connection portion 52a having a protrusion 52b that can be fitted into the pivot portion 52b is provided. At this time, the protrusion 52
b is provided at a position where it can be inserted into the hole 51 at an angle larger than the rotation angle of the blade plate 12. And hole 5
1 and the pivot connecting portion 52a, the blade holder 10 and the interlocking rod 26 are pivotally connected.

Furthermore, as shown in FIG. 12, a metal fitting 54 is inserted between the blade holder 10 and the interlocking rod 26, and a screw 5 is inserted into the circular hole 54a from the blade holder 10 side.
5, the metal fitting 54 may be shifted, the groove portion 54b may be fitted into the thin portion 55a of the screw 55, and the interlocking rod 26 may be screwed.

As explained above, according to the opening/closing window of this invention, the window can be opened and closed by rotating a plurality of vertically arranged blades via an interlocking mechanism interposed between the blades and the vertical frame. At the same time, in an opening/closing window that is closed with the lower part of the slat overlapping the upper part of the lower slat on the outdoor side so that each slat is tilted downward toward the outdoor side, there are blades at both ends in the longitudinal direction of the slat. A plate holder is provided, and the slat holder is connected to a pivoting connection portion to the interlocking mechanism, a contact portion to a tight material facing outdoors provided in the vertical frame, and a lower portion of the contact portion and below. and a stepped part for accommodating the upper part of the slat holder adjacent to the side between the tight material and the abutting part of each slat holder to be in a substantially continuous state when the slat holder is closed and inclined downward toward the outdoor side. Since the structure is such that the slat holder contacts the tight material, there is no contact between the slat holder and the tight material during opening and closing of the window, so a large force is not required when opening and closing, and the window can be closed against the tight material. A force in one direction is applied to the whole body only when the material is finished, and there is no place in the middle of the tight material where the force is applied in the opposite direction, unlike conventional methods, which eliminates early damage to the tight material and at the same time improves stability. It has excellent effects such as being able to ensure airtightness and watertightness.
