[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a take-out hanging hinge for a door for rotatably supporting a door body, and more particularly to a lower pivot hinge.

[0002]

2. Description of the Related Art Doors provided in hotel guest rooms, multipurpose halls, and the like often use take-out hanging hinges rather than hinges to rotatably support the doors, and such doors are airtight. Many are fitted with materials and require tightness with the door closed.

A conventional take-out hanging pivot hinge for a door will be described with reference to FIGS.

The upper and lower sides of the door 1 are rotatably supported by an upper pivot hinge 2 and a lower pivot hinge 3, respectively.

An upper arm 5 protrudes from an upper frame 4 of the door, and an upper bracket 6 is fixed to an upper end surface of the door body 1. The upper bracket 6 faces the upper arm 5, and the upper bracket 6 An upper pivot pin 7 protruding from the upper arm 3 is rotatably fitted to the upper arm 3.

A lower bracket 8 is fixed to the lower end surface of the door 1. The lower arm 10 provided on the side frame 9 of the door is provided with a lower pivot pin 11 projecting therefrom.
1 is rotatably fitted to the lower bracket 8.

[0007] As shown in FIG.
Is composed of an arm portion 8a to which the lower pivot pin 11 is fitted and a fixed portion 8b extending horizontally from the arm portion 8a, and the fixed portion 8b is fixed to the lower end surface of the door body 1 by a screw. It has become.

[0008]

As described above, a door provided in a hotel guest room, a multipurpose hall, or the like, is provided with an airtight material on the lower end surface of the door body in order to secure airtightness. However, in the above-mentioned conventional example, since the lower bracket 8 is screwed to the lower end surface of the door body 1, there is a problem that the airtight material cannot be attached. If the door 1 is supported by a pivot hinge and an airtight material is to be provided at the lower end, as shown in FIG.
6 was screwed to the door 1 and the airtight material 15 was fitted to the airtight material holder 16. For this reason, the airtight material holder 16 is exposed and the screw is exposed, and the design is impaired.

The present invention has been made in view of the above circumstances, and has as its object to provide a take-out hanging hinge for a door in which an airtight material can be attached to a lower end surface of a door body.

[0010]

According to the present invention, the lower arm is provided with water.
It has a flat pin seat and a fixing part perpendicular to the pin seat,
The fixed part is housed inside the side frame and the pin seat protrudes.
Attach the lower arm to the side frame so that
Arm that projects vertically and horizontally to the door panel surface
And a fixing portion parallel to the side end surface of the door body and the lower bracket.
Fix the bracket to the side end of the door body at the fixing part,
A lower pivot pin is provided on the pin seat, and the lower pivot pin is
The arm portion can be fitted .

[0011]

Since the lower bracket is fixed to the side end of the door body, the lower bracket can be attached to the lower end of the door body without damaging the appearance by attaching the lower bracket.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

1 to 3 show a lower pivot hinge, and the same components as those shown in FIGS. 6 to 8 are denoted by the same reference numerals. Since the upper pivot hinge 2 is the same as the conventional example, the description is omitted.

The lower arm 10 has a horizontal pin seat 10a,
A fixed portion 10b which is bent at a right angle to the pin seat 10a and has a substantially crank shape is provided. A part of the fixed portion 10b is housed in the side frame 9 and is fixed to the side frame 9, while the remaining portion is fixed to the side The pin receiving seat 10a protrudes from the frame 9 and extends to the protruding fixing portion 10b. A lower pivot pin 11 protrudes from the pin seat 10a.

As shown in FIGS. 4 and 5, the lower bracket 12 has an arm portion 12a projecting vertically and horizontally with respect to the door panel surface, a holding portion 12c extending horizontally from the arm portion 12a, A fixing portion 12b which is set up at a right angle to the holding portion 12c and is parallel to a side end surface of the door 1;
The arm portion 12a is provided with a pin hole 13 into which the lower pivot pin 11 is fitted.

When attaching the lower bracket 12 to the door 1, the fixing portion 12 b is inserted into the door 1, and is screwed to a side end of the door 1 in a state of facing the fixing portion 10 b of the lower arm 10. Fix it. Thus, the lower pivot pin 11 is fitted into the pin hole 13 and the door 1 is rotatably supported by the upper pivot hinge 2 and the lower pivot hinge 3.

A groove 14 is formed at the lower end of the door body 1,
An airtight material 15 is fitted into the groove 14.

As described above, in the lower pivot hinge 3 according to the present embodiment, since the fixed portion of the lower bracket 12 is fixed at the side end of the door 1, the airtight material 15 is provided at the lower end of the door 1, and Since the fixed part is housed in the door body 1, the appearance of the door is not impaired.

[0019]

According to the present invention, as described above, the door on which the airtight material is provided is supported by the pivot hinge, and an excellent effect that the aesthetic appearance is not impaired is exhibited.
