Description

[Detailed explanation of the invention] <Industrial application field> This invention is attached to the side edge of the door glass,
The present invention relates to a glass door that is used to protect the side edges of the door glass from impact and to prevent fingers from being damaged even if an accident such as a finger jamming occurs.

<Conventional technology> Conventionally, tempered glass has been mainly used for glass doors, whether they are swing opening/closing type or sliding opening/closing type, and due to their characteristics, they are relatively strong against impact from the front. However, it is extremely vulnerable to impact from the side (edge) direction, and even a small impact can often cause the entire glass to shatter and break. There was a high risk of injury to humans due to pinching.

<Problem that the invention seeks to solve> However, conventionally, no measures have been taken to protect the door glass from impacts from the side (edge) direction or from finger jamming accidents, and the situation is extremely dangerous. It was hot.

<Means for solving the problem> This device was devised in order to eliminate the above-mentioned danger, and the device is designed to prevent the recessed portion 14 of the upper stile 11 and the lower stile 12. The upper and lower ends of the glass 1 are inserted and fixed into each of the recessed parts 15, and the thickness of the front end 20 of the core material 6 of the upper stile 11 is
t' and the thickness of the front end 21 of the core material 6 of the lower stile 12
Let t' be equal to the thickness t of the glass 1, respectively,
In a glass door in which the side surface 19 of the glass 1, the front end 20 of the core material 6 of the upper stile 11, and the end surface portion 21 of the core material 6 of the lower stile 12 are bonded and fixed so that they are flush with each other, a thin metal plate is bent. to form a U-shaped section 9, and by folding back both legs of the U-shaped section 9, the glass 1 and the end surface 20 of the upper stile 11,
Clamping parts 8, 8 are formed by forming walls that clamp the end face parts 21 of the lower stile 12, respectively, and protrude toward the back side from both shoulders of the U-shaped part 9, and are spaced a little apart from both shoulders of the back. Furthermore, the frame body 2 has concave portions 28, 28 formed by bent protrusions 18, 18 toward the opposite sides thereof, and fitting portions 29, 29 are formed at one end, and the fitting portions 29, 29 are formed at one end. Part 29, 2
9 and the buffer part 7, the door stop buffer 3 is provided with a recessed groove 26, the fitting parts 29, 29 are fitted into the recessed parts 28, 28, respectively, and the recessed groove 26, By fitting the bent protrusions 18, 18, the frame 2 and buffer 3 are fixed, and the fixed frame 2 and buffer 3 are attached to the glass 1, the front end 20 of the upper stile 11, and the lower part. Front end 21 of stile 12
This is a glass door which is inserted over the respective core members 6, 6 and fixed together.

<Operation> This invention uses the above-mentioned means to bond the door glass and the stile, and straddles both the upper and lower end surfaces of the joint,
Alternatively, the end face of the door glass can be clamped and fixed at one end in the vertical and longitudinal directions by the clamping part of the frame body 2, which has a U-shaped cross section. can strengthen its resistance. In addition, in the buffer section 7 on the back of the frame 2,
It can reduce the impact when closing.

<Example> The contents of this invention will be explained below with reference to the examples shown in FIGS. 1 to 6.

In the recessed part 14 provided in the box-shaped upper stile 11 and the recessed part 15 provided in the lower stile 12, side plates 30, 30 made of stainless steel or the like are attached and fixed to both sides of the core materials 6, 6 by welding or the like. In a glass door in which the upper and lower ends of the glass 1 are inserted and the gap is filled with adhesive to fix the glass 1, the upper stile 1
1 and the lower stile 12 are the side plates 3 made of stainless steel or the like.
0, 30 and the front ends 20, 21 of the respective core materials 6, 6 are aligned and fixed so as to be on the same plane, and the thicknesses of the front ends 20, 21 are t', t' is made equal to the thickness t of the glass 1.
Furthermore, the end surface 19 of the glass 1 inserted between the upper stile 11 and the lower stile 12 is bonded with adhesive so that the end surface 20 of the upper stile 11 and the end surface 21 of the lower stile 12 are on the same surface. There is.

The frame 2 of the glass door of this invention is formed by bending a thin metal plate into a U-shaped cross section 9,
The legs 8, 8 are folded back to form the glass 1 or the upper frame 1.
The doorstop buffer 3 is fixed to the frame 2 by forming walls that clamp the end faces of the lower frame 1 and the lower stile 12, bending the protruding parts 18, 18 at both ends inward slightly away from both shoulders on the back of the U-shaped part 9 to form a recess 28, gluing a cushioning material 4 such as rubber to the inner surface of the U-shaped part 9, fitting parts 29, 29 formed at one end of the doorstop buffer 3 into the recess 28 on the outer surface, and fitting the folded protruding parts 18, 18 of the frame 2 into the recessed grooves 26, 26 provided between the fitting parts 29, 29 and the buffer part 7. Alternatively, the doorstop buffer 3 can be fixed to the frame 2 by molding. The frame 2, which has a U-shaped cross section, is fixed to the core material 6 of the glass 1 or the front ends 20, 21 of the stiles 11, 12 via the rubber cushioning material 4 fixed with an adhesive as necessary.
The cover is inserted and fixed with adhesive.
Reference numeral 2 denotes a hollow portion formed through the center of the buffer portion 7 .

Moreover, the frame 2 can also be fixed by side plates 30, 30 attached to the side surfaces of the upper stile 11 and the lower stile 12 by welding or the like.

Although the embodiments considered to be representative of the present invention have been described above, the present invention is not necessarily limited to the structures of these embodiments. It can be implemented with appropriate modification within the scope of achieving the following effects.

<Effects of the invention> With the above structure, the glass door of this invention is attached to the side edge of the glass to protect the side edge of the door glass, which is most likely to be damaged and chipped. In addition, since the door stop portion comes into close contact with the door when the door is closed, airtightness is high, and the risk of injury due to fingers being jammed can be prevented.

Furthermore, even if a torsional force is applied to the door glass, the frame body fixed to the end portion of the door glass reduces the torsional force and protects the glass.

Further, the glass door of this invention can be applied to any type of glass door, whether it is a single sliding type, a double sliding type, a swing type, etc., and can also achieve the above-mentioned effects.
