DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a double-glazed glass blind.

[0002]

2. Description of the Related Art As a conventional blind with built-in double-layer glass, there is the following one. 62-9189
No. 5 discloses a multi-layer glass in which a horizontal rotating shaft is attached to an upper portion and a horizontal rotating member is attached to a lower portion, and a number of slats are supported between the horizontal rotating shaft and the horizontal rotating member. A plurality of ladder cords are stretched so as not to be slidable relative to the horizontal rotation axis, and the horizontal rotation axis is rotatable by raising and lowering a driving force transmission member derived therefrom, and the driving force transmission member Is provided with a driven permanent magnet, and the driven permanent magnet is attracted from the outer surface of one of the glass plates by the driving permanent magnet,
The driving force transmitting member is moved up and down by moving the driving permanent magnet up and down, thereby moving the driven permanent magnet adsorbed by the driving permanent magnet up and down. Japanese Utility Model Laid-Open Publication No. 62-199002 discloses a plurality of substantially rectangular sheets having a plurality of elongated light transmitting portions arranged at predetermined intervals so that the elongated directions of the light transmitting portions match. Blinds having a function of sliding and sliding at least one of the sheets in a direction orthogonal to the elongated direction of the light-transmitting portion are provided inside the multilayer glass.

However, the conventional blind with built-in double-layer glass has the following problems. That is, in Japanese Utility Model Application Laid-Open No. 62-91895, a normal blind that transmits and blocks light by rotating a slat is used.
The width between the glasses containing this must be larger than the slat width. For this reason, a double glazing having a width of 15 mm or more between the glasses is used. However, since the width of a general double glazing is about 6 mm, there is a problem that the blind cannot be used for a general double glazing. Further, according to Japanese Unexamined Utility Model Publication No. Sho 62-199002, when the blinds are shielded from light by making the light-transmitting portions and the non-light-transmitting portions of each sheet coincide with each other, there is a gap between the sheets. Adjacent non-light-transmitting portions appear uneven. For this reason, there is a problem that the appearance is not good. The present invention is to solve such a problem.

[0004]

The present invention solves the above problem by alternately disposing fixed slats that do not move with respect to the glass and moving slats that can move substantially parallel to the glass. That is, the double-glazed glass blind of the present invention has a slat elevating mechanism and a slat row supported in alignment with the slat elevating mechanism, and the slat elevating mechanism has a fixed frame opposed to the slat row. A movable frame disposed outside the fixed frame with respect to the slat row, and the fixed frame is formed with a plurality of guide grooves extending in the longitudinal direction through the side of the fixed frame. Is composed of a part parallel to the longitudinal direction of the fixed frame and an inclined part, and the moving frame has a plurality of guide piece fixing holes in the longitudinal direction for fixing the slats on the side facing the fixed frame. The slat row is composed of fixed slats attached to a fixed frame and movable slats attached to a movable frame, and the fixed slats correspond to one movable slat in the longitudinal direction of the fixed frame. The moving slats are arranged at intervals, and the guide pieces projecting from both side ends of the moving slats are inserted into the guide grooves of the fixed frame, are fitted into the guide piece fixing holes of the moving frame, and move. The fixed slats, the moving slats and the guide groove are arranged at an interval of one fixed slat in the longitudinal direction of the frame. When the movable slats and the fixed slats overlap one another in parallel, the fixed slats and the movable slats are alternately arranged on the same plane when the guide piece of the movable frame is located at the end of the inclined portion of the guide groove. Is set as follows. Further, the fixed frame and the moving frame each have a connection protrusion protruding in the longitudinal direction at one end thereof, and a concave connection groove capable of fitting with the connection protrusion at the other end thereof. The connecting protrusions and the connecting grooves of the fixed frame forming members and the moving frame forming members may be connected to each other.

[0005]

The fixed slat is provided on the fixed frame fixed to the glass, and the movable slat is provided on the movable frame moving parallel to the glass via the guide groove of the fixed frame. Thereby, the moving slat is guided by the guide groove by moving the moving frame in the longitudinal direction thereof, forms the same plane as the fixed slat, and closes the slat and opens the slat overlapping the fixed slat. With the fixed slats. For this reason, the width dimension of the fixed frame is slightly larger than 2.6 mm (the height of one sheet is 1.3 mm) which is the height when the slats are opened and they are stacked. Therefore, the blind device can be built in a common double-layer glass having a distance between the glasses of about 6 mm. Further, when the slats are fully closed, the fixed slats and the movable slats form the same plane, that is, the slats are in the same state as ordinary blinds, so that an excellent appearance can be obtained.
