Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame door in which a mirror plate is arranged between or inside a frame frame, and more specifically, a mirror plate fitted in a fitting groove on an end face of the frame material for holding the mirror plate in the frame door. The present invention relates to a holding member. The present invention is particularly useful when a translucent plate (translucent plate) such as glass is used as the mirror plate.

When a translucent plate such as a glass plate is used as the mirror plate in the frame door, instead of directly inserting the end edge of the mirror plate into the fitting groove formed on the end face of the frame, the cross section of the fitting groove is approximately U-shaped. It is performed that the end plate holding member made of a soft resin formed in the above is fitted and the end edge portion of the end plate is fitted and held in the end plate holding member (Patent Documents 1 and 2). By doing so, it is possible to satisfactorily hold the mirror plate such as the glass plate and prevent the chatter noise from being generated due to vibration when the frame door is opened and closed.

However, according to the conventional techniques as shown in Patent Documents 1 and 2, since the end plate holding member is formed of a soft resin such as rubber, when trying to fit it into the fitting groove of the frame member, and There is a large amount of friction when trying to insert the end plate into this, making it difficult to insert them.

Further, in Patent Document 2, the glass plate holding member 3 is inserted into the groove portion 21 of the frame 2 up to the middle of the groove depth, and the end edge portion of the glass plate 1 is inserted and further pushed as it is, thereby holding the glass plate holding member. The horizontal piece 32 of 3 is drawn into the inside of the groove 21 to hold the glass plate 1 between them (paragraph 0009, FIG. 1 and the like). In the state in which the plate 1 is mounted, a gap having a width corresponding to the thickness of the horizontal piece 32 is formed between the frame 2 and the glass plate 1 at the opening of the groove 21 as shown in the upper diagram of FIG. Further, since the inner surface of the groove portion 21 where the decorative sheet is not provided is observed through the glass plate 1, the appearance is deteriorated. The same applies to the state shown in FIG. 14 of Patent Document 1.

Further, as shown in FIG. 11 of Patent Document 1, when the packing 6 (end plate holding member) is fitted so as to cover the inner surface of the groove 2a of the vertical frame 2 up to the opening edge, the above-mentioned gap is generated. Although not formed, the tip of the packing 6 made of a soft material such as rubber is exposed, and the portion of the packing 6 inside the groove 2a is also exposed through the glass plate 5. Therefore, the packing 6 which is made of a wood material and has a texture and a color greatly different from that of the frame material to which the decorative sheet is attached is observed, so that the appearance is deteriorated.

Therefore, the problem to be solved by the present invention is that even when a translucent plate is used as a mirror plate in a frame door, the fitting groove inner surface of the frame member and the mirror plate holding member are observed through the translucent plate. While preventing the deterioration of appearance, improve workability when fitting the end plate holding member into the fitting groove of the frame member or when fitting the end edge portion of the end plate into the end plate holding member, and prevent accidental insertion after fitting. It is to prevent slipping out.

In order to solve this problem, the invention according to claim 1 of the present application provides a fitting groove on an end surface of a frame member for holding a mirror plate in a frame door in which a mirror plate is arranged between or inside a frame assembly of frame members.
