[Industrial applications]

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

[0002]

[Prior art]

 For doors installed in hotel guest rooms, multipurpose halls, etc., a take-out hanging pivot hinge is often used rather than a hinge as a rotatably supporting door body, and an airtight material is attached to such a door body. Many require a tight seal when the door is closed.

A conventional take-out hanging pivot hinge for a door will be described with reference to FIGS. 6 to 8.

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

An upper arm 5 is projectingly provided on the upper frame 4 of the door, and an upper bracket 6 is fixed to the 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 body 1. Further, a lower arm 10 provided on the side frame 9 of the door is provided with a lower pivot pin 11 projectingly, and the lower pivot pin 11 is rotatably fitted to the lower bracket 8.

As shown in FIG. 7, the lower bracket 8 includes an arm portion 8a into which the lower pivot pin 11 is fitted and a fixing portion 8b extending horizontally from the arm portion 8a. 8b is fixed to the lower end surface of the door body 1 with a screw.

[0008]

[Problems to be solved by the device]

 As described above, the airtight material is attached to the lower end surface of the door body to ensure the airtightness of the door provided in the guest room of the hotel, the multipurpose hall, or the like. However, in the above-mentioned conventional example, since the lower bracket 8 is screwed to the lower end surface of the door body 1, the airtight material cannot be attached. Further, when the door body 1 is supported by the pivot hinge and an airtight material is to be provided at the lower end, the airtight material holder 16 is provided on the panel surface of the lower end portion of the door body 1 as shown in FIG. The airtight material 15 was fitted to the airtight material holder 16 by screwing. Therefore, the airtight material holder 16 is exposed and the screw is exposed, which impairs the design.

In view of the above situation, the present invention is to provide a take-out hanging pivot hinge for a door in which an airtight material can be attached to the lower end surface of the door body.

[0010]

[Means for Solving the Problems]

 The present invention is characterized in that the lower bracket that can be fitted to the lower pivot pin can be fixed to the side end of the door body.

[0011]

[Action]

 Since the lower bracket is fixed to the side edge of the door, it is possible to attach an airtight material to the lower end of the door without damaging the aesthetics by installing the lower bracket.

[0012]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

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

The lower arm 10 is composed of a horizontal pin seat 10a and a substantially crank-shaped fixing portion 10b that is bent at a right angle to the pin seat 10a. The fixing portion 10b is partially a side frame 9. It is housed inside and fixed to the side frame 9, the remaining part projects from the side frame 9, and the pin seat 10a is extended to the projecting fixing part 10b. A lower pivot pin 11 is projectingly provided on the pin seat 10a.

As shown in FIGS. 4 and 5, the lower bracket 12 has an arm portion 12a that vertically and horizontally protrudes from a door panel surface, a holding portion 12c that extends horizontally from the arm portion 12a, and It comprises a fixing portion 12b which is raised at a right angle to the holding portion 12c and is parallel to the side end surface of the door body 1, and the arm portion 12a is provided with a pin hole 13 into which the lower pivot pin 11 is fitted. There is.

When the lower bracket 12 is attached to the door body 1, the fixing portion 12b is inserted into the door body 1 and is screwed to the side end of the door body 1 while facing the fixing portion 10b of the lower arm 10. Fix it. Then, the lower pivot pin 11 is fitted into the pin hole 13 and the door body 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, and an airtight material 15 is fitted in 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 body 1, the airtight material 15 is provided at the lower end of the door body 1, However, since the fixed portion is housed in the door body 1, the aesthetic appearance of the door is not impaired.

[0019]

[Effect of device]

 As described above, according to the present invention, the door body provided with the airtight member is supported by the pivot hinge, and the excellent effect of not impairing the aesthetic appearance is exhibited.
