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 glass door.

[0002]

2. Description of the Related Art In general, since a hinge cannot be directly attached to a glass door, a metal frame 27 is mounted on an upper edge and a lower edge of a glass door plate 26 as shown in FIG. A door-side hinge member 28 provided with a bearing portion of a hinge device, and a front-side hinge member 31 at a top portion 29 and a lower portion 30 of the door frontage,
The support shaft of the front hinge member 31 is fitted to the bearing.

More specifically, as shown in FIG. 5, a mounting base 32 is provided horizontally in a frame 27 mounted on an upper portion of a glass door plate 26, and the door base hinge is provided on the mounting base 32 by screws 33. A support member 34 of the member 28 is mounted, and a bearing member 35 is mounted on the support member 34 so that the bearing hole 36 faces upward. On the other hand, a front side hinge member 31 is attached to a top part 29 of the door front side by a screw 37, and a support shaft 38 protruding downward is connected to the bearing member 3 by the screw 37.
5 is inserted from above into the bearing hole 36 and fitted.

The structure of the front hinge member at the lower portion of the glass door plate 26 is substantially the same as that described above, and a description thereof will be omitted. In the above configuration, the support shaft 38 of the front-side hinge member 31 serves as a center of rotation, and the glass door plate 26 having the door-side hinge member 28 provided with the bearing member 35 fitted thereto can rotate about the support shaft 38. Function as required doors.

[0005]

By the way, the glass door plate 26 has the property of breaking when subjected to an impact. In particular, recently, the glass door plate 26 has been devised so that the entire glass door plate 26 is crushed into small pieces. The piece is not dangerous. When the whole glass door plate 26 is crushed like this, the frame 2
7, the bearing member 35 of the door-side hinge member 28 comes off below the support shaft 38, so that the door-side hinge member 28
The frame 27 with the frame 27 falls, and this frame 27
In addition, there is a danger that a person may be hurt by glass fragments remaining on the frame 27.

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 broken, taking the above conventional problems into consideration.

[0007]

In order to achieve the above object, the present invention comprises a front side hinge member and a door side hinge member mounted on a frame above a glass door plate. The support shaft is formed so as to be fitted into the bearing body of the door side hinge member from above. A bearing cylinder is fitted in the hole of the bearing body to form a step at the lower end thereof, and a tip end of the support shaft protruding from the bearing cylinder is urged outward from the support shaft, and The door hinge device is provided with a stopper to be locked to the portion.

[0008]

In the above construction, when the glass door plate is broken and the support of the hinge member on the door side is lost, the stopper of the support shaft is engaged with the step at the lower end of the bearing tube, and the support shaft and the bearing tube are fitted. The door side hinge member having the bearing structure is held by the front side hinge member, and the door side hinge member and the frame to which the door side hinge member is attached do not fall.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a door hinge device according to the present invention will be described below with reference to FIGS. In the figure, reference numeral 1 denotes a front side hinge member, and a base part 2 is fixed to a top part 4 of the front side by screws 3. The front side hinge member 1 has a support shaft 5 which can protrude below the base portion 2. On the upper part of the base 2, a lever 7 whose mid abdomen is pivotally supported by a pivot 6
One end of the lever 7 is pivotally connected to the support shaft 5, and the other end is vertically displaced by an operating screw 8.

The door side hinge member 9 is a U-shaped support 10
And the bottom of the support 10 is
1 is fixed by screws 13 to a horizontal mounting base 12 provided inside. A bearing 14 is provided on the bottom of the support 10.
And a screw hole 15 formed in a lateral direction of the bearing body 14 with a screw bolt 15 passing through both end pieces of the support body 10.
Screwed. The frame 11 is mounted on the upper part of the glass door plate 17. And frame 11
An adjustment hole 18 is formed at a position corresponding to the end of the screw bolt 15.

As shown in FIG. 3, the bearing body 14 is provided with a hole 19 opening upward, and a bearing cylinder 20 is press-fitted into the hole 19 and fixed. The lower end of the bearing cylinder 20 forms a step 21 projecting inward with respect to the inner wall of the hole 19, and the step 21 is spaced from the inner bottom of the hole 19. On the other hand, the front side hinge member 1
The support shaft 5 has a diameter suitable for the bushing 20, has a length penetrating the bushing 20, and has a lateral hole 22 at a lower end thereof. A screw body 23 is screwed into the hole 22, and an urging body 24 formed of a coil spring is provided at a tip end of the screw body 23, and the urging body 24 is urged by the urging body 24 in a direction protruding to the side of the support shaft 5. A stopper 25 made of a ball is provided.

In the above configuration, the front side hinge member 1 and the door side hinge member 9 are connected as follows. First, the support shaft 5 of the front hinge member 1 is retracted from the base 2 by operating the lever 7. Here, the door is fitted into the frontage, and the position is adjusted with the screw bolt 15 so that the bearing body 14 corresponds to the support shaft 5. Thereafter, the lever 7 is operated to cause the support shaft 5 to protrude from the base portion 2 and is inserted into the bearing tube 20 of the bearing body 14, and the tip of the support shaft 5 is
Protrude below 0. A stopper 25 made of a ball at the tip of the support shaft 5 protruding below the bearing cylinder 20.
Is prevented from moving upward by the stepped portion 21 formed at the lower end of the bushing 20, so that the support shaft 5 does not fall out of the bushing 20. Note that the stopper 25 is urged by an urging body 24, and when the support shaft 5 is inserted into the bearing cylinder 20,
The insertion of the support shaft 5 in the hole 22 of the support shaft 5 is performed without any trouble.

As described above, the support shaft 5 of the front-side hinge member 1
When the door 2 is inserted into the bearing sleeve 20 of the door side hinge member 9, the stopper 2
The engagement of the support shaft 5 and the bushing cylinder 20 is not released due to the locking of the support shaft 5. Therefore, when the glass door plate 17 is damaged, that is, when the support of the door side hinge member 9 is lost, the door side hinge member 9 is held by the front side hinge member 1, and the door side hinge member 9 Since the combined frame 11 does not fall, safety is ensured.

In the above embodiment, the support shaft 5 is moved up and down by the lever 7, but it may be configured without the lever 7. If the dimensional accuracy at the time of manufacture is maintained, the position adjusting member of the bearing body 14 may be omitted. Further, although the stopper 25 of the support shaft 5 is a ball, it may be other than a ball, and the biasing body 24 may be an elastic body other than a coil spring.

[0015]

As is clear from the description of the above embodiment,
In the door hinge device of the present invention, when the support shaft of the front-side hinge member is fitted to the bearing body of the door-side hinge member, a stopper is provided at the tip of the support shaft, the bearing body is provided with a bearing cylinder, and the step portion is provided at the lower part. Is formed so that the support shaft and the bearing body are not disengaged from each other, so that even if the glass door plate is damaged and the door-side hinge member is no longer supported, the door-side hinge member is held by the front-side hinge member. The danger due to the fall is eliminated without being dropped and the effect is great.
