Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door hinge device to be combined with a door made of glass.

[0002]

2. Description of the Related Art As a door hinge device for supporting a glass door plate around a rotation center located outside the thickness range of the glass door plate, there is conventionally known a door hinge device constructed as shown in FIG.

Referring to the drawings, reference numeral 1 is a glass door plate, and metal frames 2 and 3 are attached to the upper and lower edges of the glass door plate 1. The glass door plate 1 has a center of rotation located outside the thickness range of the glass door plate 1, and a lower end of the glass door plate 1 mounted on the lower end of the metal frame 3 so as to project outward.
Is fitted to the support shaft 7 of the lower frontage side hinge member 6 and is rotatably supported. Further, the upper end of the glass door plate 1 is provided with a shaft mounting member 8 attached to the upper end of the metal frame 2 so as to project outward. It is rotatably supported by being inserted from below into a bearing hole 12 of a bearing member 11 mounted so as to project outward on 10. More specifically, the support shaft 9 is inserted into the mounting hole 13 of the shaft mounting member 8 from below, and the male screw portion 14 on the outer surface of the large diameter portion on the lower side of the support shaft 9 is screwed into the female screw portion 15 on the inner surface of the mounting hole 13. A female screw hole that is inserted and is oriented in the horizontal direction at a proper position in the circumferential direction of the shaft mounting member 8.
The tip of the screw pin 17 screwed into 16 is pressed against the small-diameter neck portion 18 below the male screw portion 14 of the support shaft 9, whereby the support shaft 9 is prevented from slipping into the mounting hole 13 of the shaft mounting bracket 8. Has been done. A bearing 19 is provided in the bearing hole 12 of the bearing member 11 attached to the front-side hinge member 10 to support the support shaft 9 protruding upward from the shaft mounting member 8.

In the above structure, the glass door plate 1 functions as a required door with the support shafts 7 and 9 located outside the thickness range of the glass door plate 1 as rotation centers.

[0005]

By the way, the glass door plate 1 has a property that it breaks when it receives an impact. Especially, recently, the glass door plate 1 has been devised so that the entire glass door plate 1 is crushed into a knuckle. A piece of glass is used to prevent danger. In this way, when the entire glass door plate 1 is crushed into a cocoon, the frame 2 attached to the upper part
Since the support shaft 9 provided on the shaft via the shaft mounting metal fitting 8 comes out below the bearing hole 12 of the bearing member 11 mounted on the upper frontage side hinge member 10, the upper frame 2 falls and the frame 2 and There is a risk that the glass fragments remaining on the frame 2 may injure a person.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a door hinge device in which the upper frame does not drop even if the glass door plate is damaged.

[0007]

In order to solve this problem, the present invention is a door hinge device for supporting a glass door plate around a rotation center located outside the thickness range of the glass door plate. A metal frame is provided on the upper side of the plate, and a shaft is provided so as to project upward from a shaft mounting metal fitting that is mounted so as to project from this frame. The gist of the present invention is that a pin is inserted into a bearing hole of a member from below, and one end of the spindle is inserted into the bearing hole of the bearing member and protrudes upward from the bearing hole so that one end thereof protrudes. Is.

With this structure, even if the glass door plate is damaged and the upper metal frame and the glass fragments remaining on the frame are about to fall, the one end protruding portion of the pin is caught on the upper end of the bearing member, The frame and the glass fragments remaining on the frame can be prevented from falling, and a safe door hinge device can be provided.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to the drawings. In FIGS. 1 and 2, reference numeral 21 denotes a glass door plate, and metal frames 22 are attached to the upper and lower edges of the glass door plate 21, respectively. The drawing shows only the upper end of the glass door plate 21, and the lower end of the glass door plate 21 is omitted.

The center of rotation of the glass door plate 21 is located outside the thickness range of the glass door plate 21, and the lower end of the glass door plate 21 has a bearing hole of a bearing member attached to the lower end of the metal frame so as to project outward. It is rotatably supported by being fitted to a support shaft of the lower frontage side hinge member (not shown). Also,
The upper end of the glass door plate 21 is attached to the upper end of the metal frame 22 by a shaft mounting metal fitting 23 mounted so as to project outward, and a support shaft 24 provided so as to project upward is attached to the upper frontage side hinge member 25. Bearing member 26 installed so as to project outward 26
The bearing hole 27 is inserted from below and is rotatably supported. More specifically, the support shaft 24 is inserted into the mounting hole 28 of the shaft mounting member 23 from below, and the male screw portion 29 on the outer surface of the large diameter portion of the support shaft 24 is screwed into the female screw portion 30 on the inner surface of the mounting hole 28. Insert it and press the tip of the screw pin 32 screwed into the female screw hole portion 31 facing the horizontal direction at the proper position in the circumferential direction of the shaft mounting bracket 23 against the small diameter neck portion 33 below the male screw portion 29 of the support shaft 24. As a result, the support shaft 24 is prevented from coming off from the mounting hole 28 of the shaft mounting member 23. In the bearing hole 27 of the bearing member 26 attached to the front-side hinge member 25, a bearing 34 for supporting the support shaft 24 projecting upward from the shaft mounting member 23 is provided. The tip end 24a of the support shaft 24 inserted into the bearing hole 27 of the bearing member 26 projects upward from the bearing hole 27, and one end of the support shaft 24 is formed in a horizontally oriented female screw hole portion 24b formed at the tip end 24a of the support shaft 24. The screw pin 35 is screwed in so as to project.

Therefore, with the above structure, when the glass door plate 21 is crushed due to an impact, even if the upper metal frame 22 and the glass fragments remaining on the frame 22 try to fall, One end projecting portion of a screw pin 35 attached to the female screw hole portion 24b of the tip end 24a of the support shaft 24 so as to project one end is caught on the upper end of the bearing member 26, and the frame 22 and the glass fragments remaining on the frame 22 Can be prevented from falling.

[0012]

As described above, according to the present invention, even if the glass door plate is damaged and the upper metal frame and the glass fragments remaining on this frame are about to fall,
Insert the support shaft, which is provided so as to project upward from the shaft mounting bracket that is mounted so as to project from this frame, into the bearing hole of the bearing member that is mounted so as to project from the upper front side hinge member from below, By providing the pin so that one end projects at the tip of the support shaft that is inserted into the bearing hole of the bearing member and projects upward from the bearing hole, the one end projecting portion of the pin is caught on the upper end of the bearing member, The frame and the glass fragments remaining on the frame can be prevented from falling, and a safe door hinge device can be provided.
