  The double-glazed glass is configured by arranging two glass plates so as to face each other via a sealing portion provided at an edge, and forming a space portion between the two glass plates. In the conventional blind built-in type multi-layer glass, an operation mechanism for operating the slats is provided in the space between the glass plates, and this is operated using a magnet through the glass plates. Accordingly, since the entire periphery of the blind built-in type double-glazed glass is composed of a glass plate and a sealing portion, it has the same structure as a normal double-glazed glass and is housed in a shoji frame.

  When the double-glazed glass is placed in the housing, the edge of the double-glazed glass is housed in a recess formed on the inner peripheral surface of the housing, and is further fixed by a glass pressing part that sandwiches the indoor and outdoor surfaces of the double-glazed glass. I was doing. In addition, in order to increase the fixing strength, a double-sided glass pin is inserted into the sealing part on the outer periphery of the multi-layer glass so that the multi-layer glass does not come out of the recess of the housing. It was.

  As described above, when the operation mechanism is sealed between the glass plates, a magnet is used for the operation. However, it is necessary to prevent the generation of a magnetic field, or the operation of the slat is performed from the viewpoint of cost stabilization. Therefore, it is required to have a configuration in which no magnet is used. In this case, it is necessary to provide an operation mechanism outside the space between the multiple glass layers.

  By making the operating body having an operating mechanism provided outside the space of the double-glazed glass into a plate shape having the same thickness as the double-glazed glass, the operating body and the double-glazed glass are integrated and housed in the housing, and a glass pressing part It can be fixed with. However, since there is no sealing portion on the side where the operating body is disposed, the fixing strength cannot be increased as it is, and when the strength of the housing is low, the operating body comes out of the recess of the housing. There was a risk of it.

The present invention has been made in view of the above problems, and includes a blind built-in multilayer that can increase the fixing strength including the side where the operation body is provided even if the operation mechanism is provided outside the multilayer glass. It aims at providing the shoji which has glass.

In order to solve the above-mentioned problem, the shoji according to the present invention forms a glass body having a space portion inside by arranging two glass plates facing each other through a sealing portion provided at an edge, and in the space portion.

On the outer peripheral edge portion of the operation body, hook ribs are formed on the outer surface of the room so as to protrude toward the outside of the room ,
A glass storage groove is formed on the inner peripheral surface of each of the upper and lower ridges and the vertical ridge, and the peripheral edge portion of the blind built-in type multi-layer glass is placed and fixed in the glass storage groove via a glass pressing part. The holding part has a holding part that holds the indoor / outer surface of the built-in blind double-glazed glass, and the holding part has a facing part facing toward the back side of the glass storage groove, and the hooking part and the hooking part The structure is characterized in that the ribs face each other.

Further, in the shoji according to the present invention, the operating body includes at least a metal member that constitutes an outdoor side surface and an outer peripheral surface, and a resin member that constitutes at least an indoor side surface. It is formed as a feature.

According to the shoji according to the present invention, the outer peripheral edge portion of the operation body is formed with the hook ribs projecting toward the indoor / outdoor direction on the indoor / outer surface. When it is housed in the shoji frame, it is possible to prevent the side having the operating body from coming out of the housing, and to increase the fixing strength including the side where the operating mechanism is provided.

Further, according to the shoji according to the present invention, since the hook rib inside and outside the metal member is formed on the metal member, it is difficult to be deformed even if a force is applied to the hook rib, and the fixing strength can be further increased.

  Furthermore, according to the shoji according to the present invention, the sandwiching portion of the glass pressing part has an opposing surface portion facing toward the back side of the glass storage groove, and the opposing surface portion and the hooking rib are opposed to each other. When a force is applied in the direction in which the layer glass is removed from the housing, the opposing surface portion and the hooking rib are brought into contact with each other and engaged with each other, so that the prevention of removal can be ensured.
