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 door structure described above, the outdoor side surface of the glass plate 21 is recessed and stepped from the outdoor side surfaces of the upper and lower frames 22 and 23, so that the glass plate 21 and the column 24 on which the wall plate B is fitted are connected. This creates a large gap between them, which causes drafts to enter.Furthermore, the level difference between the upper and lower frames 22, 23 and the glass plate 21 tends to get dirty, and furthermore, this level difference The design was also unnatural.

In addition, if the shape of the door body is asymmetrical between the indoor side and the outdoor side, there will be a distinction between right-hand and left-hand when attaching a lock or handle, and care must be taken not to confuse the indoor side with the outdoor side. Since this is a hassle in terms of inventory management, it is better to have a symmetrical shape on both the indoor and outdoor sides and to be able to install it without regard to the front or back.

The above-mentioned problem was that there was a large gap between the outdoor side of the glass plate and the side of the wall plate support that faces the door body, and that there was a step between the upper and lower frames and the glass plate. It happened because of this.

Furthermore, when used as an automatic door, there is a possibility that people or objects may collide with it, so it is necessary to maintain sufficient strength of the glass plate.

(Technical Problem) The purpose of this invention is to solve the above-mentioned problem, and the technical problem to solve this problem is to minimize the gap between the glass plate and the column, and to
The strength of the glass plate can be reasonably and sufficiently ensured, there is no difference in level between the upper frame and lower frame and the glass plate, and the indoor side and outdoor side are symmetrical and can be installed without any front-back relationship. Our goal is to provide a door structure that is possible.

(Technical means to solve the problem) The upper and lower ends of the main glass plate are fitted and bonded to the upper and lower frames, and adhesive films are applied to almost the entire surface of both the indoor and outdoor sides of the main glass plate, respectively. The reinforced glass plates are integrally and tightly bonded, and the outdoor side surfaces of the outdoor side reinforced glass plate are substantially flush with the outdoor side surfaces of the upper and lower frames, and the indoor side surfaces of the indoor side reinforced glass plate are connected to the upper and lower frames. It is approximately flush with the interior side of the interior.

(Function) Reinforcing glass plates are closely integrated with both the outdoor and indoor sides of the main glass plate via adhesive films, forming a three-panel laminated glass unit to increase the strength of the glass surface. In addition, both reinforced glass plates fill in the recesses formed on the outdoor and indoor sides of the main glass plate and the steps formed at the boundaries between the upper and lower frames and the main glass plate.

(Effects) Since the present invention has the above configuration, the gap between the door and the support supporting the wall can be kept to the minimum width to prevent contact between the two, allowing entry from between the two. Drafts can be almost eliminated.

3 through adhesive sheets on both sides of the main glass plate.
Since the two glass plates are tightly bonded together, it is possible to significantly increase the strength of the glass surface of the door, and the three glass plates are bonded together in a clean state with no spots caused by the adhesive. be able to. Furthermore, in the unlikely event that the glass plate breaks,
The adhesive force of the adhesive film can prevent glass fragments from scattering.

Moreover, since both the indoor side surface and the outdoor side surface are flat, they can be attached regardless of the front and back relationship.

Since there is no level difference between the upper and lower frames and the reinforced glass plate, it is difficult to get dirty and easy to wipe clean.Furthermore, since the door body has a flat plate shape with no level difference, it is natural in terms of design. It becomes more refined.

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

FIG. 1 shows a longitudinal section of a door A, which consists of a main glass plate 1, upper and lower frames 3 and 4 fitted and bonded to the upper and lower edges of this main glass plate, and the main glass plate. It consists of reinforcing glass plates 2b and 2a attached to both the indoor and outdoor sides of 1.

The main glass plate 1 is made of tempered glass that is approximately the same size as the doorway C, and is approximately 6 mm thick, which is approximately half the thickness of the glass plate used for conventional doors (approximately 12 mm). Reinforced glass plates 2a and 2 are provided on both the outdoor and indoor sides of the same plate 1, excluding the upper and lower parts.
3 glass plates 1 and 2 with b attached on the entire surface.
Integrate a and 2b.

The reinforcing glass plates 2a and 2b are ordinary raw glass plates, and are pasted on both sides of the main glass plate 1 with transparent double-sided adhesive films 14 interposed therebetween. Note that a translucent film, a colored film, or a single-sided reflective film may be used as the adhesive film.

The upper frame 3 to be fitted to both the upper and lower edges of the main glass plate 1 is a long plate formed with an H-shaped cross section. In addition to recessing the lower edge side, the same plate 1
A mounting groove 3b is recessed in the upper edge, and the suspension plate 5 is inserted into the groove 3b and fixed with adhesive or a set screw 6.

Further, the lower frame 4 has exactly the same shape as the upper frame 3, and a steady rest plate 7 is fitted into the mounting groove 4b and fixed with a set screw 8.

After the above-mentioned upper and lower frames 3 and 4 are fitted to the upper and lower edges of the main glass plate 1, the boundaries between the fitting grooves 3a and 4a of the upper and lower frames 3 and 4 and the mounting grooves 3b and 4b are Adhesive is injected through the injection port 9 drilled in the portion , filling the gaps between the inner surfaces of the fitting grooves 3a and 4a and the main glass plate 1, and bonding them together. Incidentally, since the upper and lower edges of the main glass plate 1 are fully bonded within the fitting groove of the frame, the degree of safety against falling off is extremely high.

As mentioned above, when attached to both the upper and lower edges of the main glass plate 1 of the upper and lower frames 3 and 4, the outdoor side of the upper and lower frames 3 and 4 and the outdoor side of the reinforced glass 2a, and the The side surface and the indoor side surface of the reinforced glass 2b are flush with each other, and the indoor side and the outdoor side of the door A are symmetrical.

The door A opens and closes on the indoor side of the wall board B installed beside the entrance C, and the above-mentioned hanging plate 5 is mounted on the hanging rail 10 fixed to the lintel at the installation position of the door A. At the same time, the door A is suspended by the suspension rail 10 by fitting the grooved wheel 13 pivotally supported on the tip of the lower frame 4 and fitting the steady rest plate 7 at the lower end of the lower frame 4 into the groove 12 provided on the floor surface. It can be opened and closed freely in the closed state.

As shown in FIG. 1, the gap between the door A, which has a planar exterior surface with no steps, and the support column 11 that supports the wall B is a minimum width of about 5 mm to prevent the two from coming into contact. 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 gap when door A is closed.

The door A described above has a flat plate shape with no steps, so it has a natural and elegant design.
2b are closely integrated with each other through the adhesive film 14, so that the strength can be greatly increased. Furthermore, compared to glass plates bonded together with adhesive, the bonded surface is free from unevenness, and it is possible to maintain transparency similar to that of a single piece of glass.

Furthermore, even if the main glass plate 1 or the reinforcing glass plates 2a, 2b are broken, the adhesive film 1 interposed between the respective glass plates 1, 2a, 2b will be damaged.
Due to the adhesive force of 2, it is possible to prevent broken glass fragments from scattering, and it is also possible to improve the safety of the door structure using the glass plate.
