Abstract

PROBLEM TO BE SOLVED: To provide a construction of a waterproof door which does not sag even though the door is very heavy but comes in tightly contact with a door stop and moreover can be installed in a short time. SOLUTION: At a one-shaft hinge type waterproof door, a shaft 3 is fitted to a binge hardware 4 at the door stop side. A rectangular linking hole 5 is provided in the hinge hardware 4' at the door side, a slide bearing 6 having a square cross section with the shaft 3 fixed to this linking hole 5 is loose fit, and the linking hole 5 is made as a linking hole permitting the movement of the slide bearing 6 between the clearance d, d'.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a uniaxial hinged waterproof door used for a floodgate, a waterproof door and the like.

[0002]

2. Description of the Related Art Conventionally, when a waterproof door with a one-axis hinge is installed on site, an error is corrected by inserting a liner between the hinge hardware and the door stop so that the waterproof door and the door stop are in close contact with each other when the door is closed. However, since the door once installed must be attached and detached in order to insert the liner, when the weight of the waterproof door is large, it takes a lot of trouble and time to adjust. In addition, since half of the external force such as water pressure applied to the door is received by the hinge hardware, the hinge hardware also becomes larger in proportion to the external force.

In the case where the door is relatively light, this problem has been solved by using a biaxial hinge. However, in the case of a heavy door, a biaxial hinge can be used because the door hangs. I could not do it.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a door having a heavy contact with a door and a close contact with the door without using a heavy liner. An object of the present invention is to provide a waterproof door structure in which the mounting operation can be completed in a short time, and a part of external force such as water pressure applied to the door is uniformly applied to the door without being applied to the hinge hardware.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems. In a waterproof door of a one-shaft hinge, a shaft is attached to a hinge hardware on a door stop side, and a door-side hinge is provided. The hinge hardware is supported by a slide bearing that can move in and out in the door stop direction.

[0006]

According to the present device, the hinge side of the door can move in and out in the door stop direction, so that the joint surface between the door and the door stop can be brought into close contact with no gap even if the door hinge hinge is not properly mounted.

[0007]

FIG. 1 is a partial cross-sectional plan view showing an embodiment of the present invention, FIG. 2 is a front view of FIG. 1, FIG. 3 is an enlarged front view of a hinge portion, and FIG. FIG. 4 is a cross-sectional view taken along a line A.

1 to 4, reference numeral 1 denotes a waterproof door, 2 denotes a door stop, 3 denotes a hinge shaft, and a shaft 3 is mounted on a hinge fitting 4 on the door stop side, and a hinge fitting 4 on the waterproof door 1 side. Is the engagement hole 5
Is supported by a slide bearing 6 which is loosely fitted to the shaft.

The opening and closing of the waterproof door 1 is performed by turning a handle 8 of the door opening / closing device 7 and expanding and contracting an actuator 9 connected to a substantially center of the waterproof door 1. A supporting member 10 and a waterproof rubber 11 are provided on the periphery.

The slide bearing 6 has a square cross section, and the engaging hole 5 into which the slide bearing 6 is loosely fitted is large enough to absorb the collapse of the waterproof rubber 11 (d + d in the embodiment). 'Length is large) and the slide bearing 6 has a clearance d,
It is configured to be able to move during d '. Therefore, the distance L ₂ from the axis of the shaft 3 to the door stop 2 from the appropriate dimension L _1.
The sliding bearing 6 is configured to be movable even if the water pressure is large, small, or distorted.
The door 1 and the door stop 2 can be brought into close contact with each other without causing a gap between the door support member 10 and the supporting member 10, and the entire door is transmitted to the door stop without receiving external force applied to the door with the hinge hardware. You can do it.

Therefore, the troublesome work of installing the liner is not required, and the work of installing the waterproof door is significantly simplified.

FIG. 5 shows another embodiment of the slide bearing and the engagement hole of the hinge metal according to the present invention. FIG. 5 (a) shows the engagement hole 5 'and the slide bearing 6' formed in an oval shape. FIG. 5 (b) shows the engagement hole 5 "and the slide bearing 6" at both ends in a polygonal shape. However, it is needless to say that the same operation and effect as in the above embodiment can be obtained. .

From the above, it goes without saying that the cross-sectional shapes of the engagement hole and the slide bearing may be any shapes as long as the slide bearing can move.

[0014]

As described above, according to the present invention, when the door is closed, there is no need to perform an adjustment work such as interposing a liner so that the waterproof door 1 is in close contact with the door stop 2, so that the mounting work is remarkably performed. This has the effect of being easier. Moreover, the waterproof door 1
Is a structure that cannot move in the horizontal direction even if it can move between the clearances d and d 'in the door stop direction. Therefore, even with a heavy door, the free end of the door does not hang down, and a heavy floodgate is provided. And the structure of the waterproof door.
