Description

[Detailed description of the invention] (Industrial application field) This invention relates to a door structure, and particularly to a door structure used for automatic doors.

(Prior Art) Conventionally, the door A' structure used for automatic doors is as shown in FIGS. 3 and 4, in which upper and lower portions having a roughly H-shaped cross section are formed on both upper and lower edges of a glass plate 21 made of tempered glass. The frames 22 and 23 are fitted and installed, and the upper frame 22 is suspended by a rail provided on the lintel at the entrance and exit, and the lower frame 23 is supported by a guide groove 25 recessed in the floor, and the closing movement of the entrance and exit side is carried out. It can be opened and closed freely between the side position and the opening side position, which overlaps the indoor side surface of the wall plate B installed beside the entrance.

However, in the above-mentioned door structure, a large gap is created between the outdoor surface of the door body A' and the surface of the support 27 that supports the wall board B, which faces the glass plate 21, which causes drafts to enter through this gap. have.

The above-mentioned problem is due to the fact that a large gap was created between the outdoor side surface of the glass plate and the surface of the support column supporting the wall surface facing the door body.

Furthermore, when used as an automatic door, it is necessary to maintain sufficient strength of the glass plate because it is easily hit by people or objects.

(Technical Problem) The purpose of the present invention is to solve the above-mentioned problem, and the technical problem to solve this problem is to prevent the above-mentioned gap from occurring and to maintain the strength of the glass plate to a reasonable and sufficient level. It is an object of the present invention to provide a door structure that can secure the following conditions.

(Technical means for solving the problem) The technical means taken by the present invention to achieve the above-mentioned purpose is to insert the upper and lower edges of the main glass plate into the upper and lower frames from the center of their thickness. The reinforcing glass plate is fitted with the main glass plate offset outwardly, and a reinforcing glass plate is integrally and tightly bonded to substantially the entire outdoor side surface of the main glass plate via an adhesive film, and the outdoor side surface of the reinforcing glass plate is attached to the upper and lower frames. It is approximately flush with the outdoor side of the roof.

(Function) A reinforcing glass plate is closely integrated with the outdoor side surface of the main glass plate via an adhesive film, forming a laminated glass and increasing the strength of the glass surface. Further, the reinforced glass fills a recess formed from the outdoor side surface of the main glass plate to the outdoor side surfaces of the upper and lower frames.

In addition, by deviating the upper and lower edges of the main glass plate by a predetermined amount toward the outdoor side from the center of the thickness with respect to the upper and lower frames, the outer side of the main glass plate can be moved from the outdoor side of the upper and lower frames to the outdoor side of the upper and lower frames. The width (thickness of the reinforced glass) is set to a predetermined dimension.

(Effects) Since the present invention has the above-described configuration, the gap between the door and the support supporting the wall surface can be kept to the minimum width to prevent contact between the two, and the gap that can be entered from between the two. You can almost eliminate wind.

Since the two glass plates are tightly bonded together via an adhesive sheet, it is possible to significantly increase the strength of the glass surface, and it also prevents unevenness of the adhesive between the two glass plates. It can be attached in a clean state. Furthermore, even if the glass plate should break, the adhesive force of the contact film can prevent glass fragments from scattering.

Furthermore, since both the upper and lower edges of the main glass plate are offset from the center of thickness toward the outdoor side with respect to the upper and lower frames, there is a recess from the outdoor side of the main glass plate to the outdoor side of the upper and lower frames. The depth of the reinforcing glass plate, that is, the thickness of the reinforced glass plate can be made as thin as the strength of the upper and lower frames allows.

(Example) An example of the present invention will be described below based on the drawings.

FIG. 1 shows a longitudinal cross section of a door A, which has a main glass plate 1 with a reinforced glass 4 attached to its exterior side,
It is composed of an upper frame 2 and a lower frame 3 that fit onto both upper and lower edges of the main glass plate 1.

It is made of tempered glass that is approximately the same size as the entrance/exit C of the main glass plate 1, and is approximately 6 mm thick, which is approximately half the thickness of the glass plate (approximately 12 mm) used for conventional doors. Reinforced glass 4 is entirely adhered to the outdoor side surface of the board 1 except for the upper and lower edges, so that both glasses 1 and 4 are integrated.

An ordinary raw glass plate is used for the reinforced glass 4,
A transparent double-sided adhesive film 12 is attached to the outdoor side surface of the main glass plate 1 described above. Note that a translucent film, a colored film, or a single-sided reflective film may be used as the adhesive film.

The upper frame 2, which is fitted to both the upper and lower edges of the main glass plate 1, is a long plate having a substantially H-shaped cross section, and has a fitting groove 2a into which the upper edge of the main glass plate 1 is fitted.
is recessed in the lower edge of the frame 2, and the plate 1
Engagement groove 2 to which a suspension fitting 5 to be described later is coupled to the upper edge
b is recessed.

The fitting groove 2a is provided eccentrically toward the outdoor side from the center of the thickness of the upper frame 2, and the thickness of the outdoor side surface of the groove 2a and the outdoor side surface of the upper frame 2 is determined by the thickness of the reinforced glass 4.
Make it about 6mm, the same as. Further, engaging pieces 2c, 2c are provided on the inner surface of the engaging groove 2b to face each other, and the hanging bracket 5 is engaged with and fixed to the engaging pieces 2c, 2c.

The lower frame 3 has exactly the same shape as the upper frame 2, and is fitted to the lower edge of the main glass plate 1 so that the fitting groove 3a is eccentric toward the outdoor side, and a steady rest plate 6 is provided in the engagement groove 3b. engage.

The above-mentioned upper and lower frames 2 and 3 are fitted to the upper and lower edges of the main glass plate 1, and then bored in the area between the fitting grooves 2a and 3a and the engaging grooves 2b and 3b. Inject the adhesive from the injection hole 7 and fill the fitting groove 2.
The gap between the inner surface of a and 3a and the main glass plate 1 is filled and the two are bonded together. Furthermore, since the upper and lower edges of the main glass plate are fully bonded within the fitting groove of the frame, the degree of safety against falling off is extremely high.

As mentioned above, when the upper and lower frames 2 and 3 are fitted to the main glass plate 1, the outdoor side surfaces of the upper and lower frames 2 and 3 and the outdoor side surface of the reinforced glass 1 are approximately as shown in FIG. Become flush.

The door A opens and closes on the indoor side of the wall board B installed next to the entrance C, and the above-mentioned hanging bracket is mounted on the hanging rail 8 fixed to the lintel at the installation position of the door A. At the same time, a grooved wheel 9 pivotally supported at the tip of the lower frame 3 is fitted, and a steady rest plate 6 at the lower end of the lower frame 3 is fitted into a groove 10 provided on the floor surface, and the door A is suspended by the suspension rail 8. It can be opened and closed freely when held.

As shown in Fig. 1, the gap between the door A, which has a planar exterior surface with no steps, and the pillar 11 that supports the wall board B is a minimum width of about 5 mm to prevent both A and 11 from coming into contact. becomes. This gap is less than half of the conventional gap distance (approximately 13 mm), and it is possible to almost eliminate drafts that enter through the same gap when door A is closed.

Furthermore, by closely integrating the main glass plate 1 and the reinforcing glass plate 4 via the adhesive film 12, it is possible to ensure the same strength as the glass plates of the thickness stacked together, and it is also possible to Compared to the case where the adhesive is bonded together, there is no unevenness on the adhesive surface, and the same transparency as that of a single piece of glass can be ensured.

Furthermore, even if the main glass plate 1 or the reinforcing glass 4 breaks, the adhesive force of the adhesive film 12 interposed between both glasses 1 and 4 will prevent the broken glass fragments from scattering. I can,
It is also possible to improve the safety of door structures using glass plates.
