Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a door hinge.

[0002]

[Prior art]

 As shown in FIG. 6, at the doorway (1) of the building, the door frame (4) is fitted into the opening (3) of the building structure (2), and the hinge (4) is attached to the door frame (4). A structure is adopted in which the door (5) is attached via 6,6).

Conventionally, as shown in FIG. 7, the hinge (6) includes a fixed piece (7) attached to the door frame (4) and a movable piece (8) attached to the door (5). A shaft tube (9, 10) is provided at the joint edge of each of the piece (7) and the movable piece (8), and a spindle pin (11) is fixed to the shaft tube (9) of the fixed piece (7). However, there is provided a structure in which the support shaft pin (11) is fitted in the shaft hole (10A) of the shaft tube (10) of the movable piece (8).

[0004]

[Problems to be solved by the device]

 The door (5) is usually attached to the door frame (4) via hinges (6, 6) and transported to the construction site, and is attached to the opening (3) of the building vehicle (2) together with the door frame (4). It may be installed, but it may be removed from the door frame (4) during the construction work so that the door (5) does not interfere with the work and the door (5) is not damaged. In the above conventional hinge (6) configuration, when removing the door (5) from the door frame (4) as shown in FIG. 8, lift the door (5) upward as shown by the arrow to remove the hinge (6). When attempting to pull out the shaft tube (10) of the movable piece (8) from the support shaft pin (11) fixed to the shaft tube (9), the casing is covered by the building driver (2) and door frame (4). When worn, the casing may interfere and prevent the door (5) from being lifted up. In such a case, it is necessary to remove the hinge (6) from the door frame (4) or the door (5), and it is very troublesome to remove the door (5) from the door frame (4). It

[0005]

[Means for Solving the Problems]

 As a means for solving the above conventional problems, the present invention comprises a fixed piece (17) attached to a door frame (4) and a movable piece (18) attached to a door (5). A shaft tube (19, 20) is provided at the joint edge of (17) and the movable piece (18), and the fixed piece (17) and the shaft tube (19, 20) of the movable piece (18) are provided. It is intended to provide a door hinge (16) in which a spindle pin (21) is detachably fitted into a shaft hole (19A, 20A) of the shaft tube (19, 20) by polymerizing each other.

[0006]

[Action]

 In the hinge (16) of the present invention, the fixed piece (17) is attached to the door frame (4) and the movable piece (18) is attached to the door (5). If the spindle pin (21) fitted in the shaft hole (19A, 20A) of the shaft tube (19, 20) of the piece (18) is pulled out from the shaft hole (19A, 20A), the hinge (16) The movable piece (18) can be removed from the fixed piece (17).

[0007]

【Example】

 One embodiment of the present invention is shown in FIGS. The hinge (16) shown in the figure consists of a fixed piece (17) attached to the door frame (4) and a movable piece (18) attached to the door (5). A shaft tube (19, 20) having a shaft hole (19A, 20A) is integrally provided at a joint edge portion with the piece (18). The shaft hole (19A) of the shaft tube (19) of the fixing piece (17) is provided with a screw hole portion (19B), and a spindle pin (21) is fitted in the shaft hole (19A). However, the spindle pin (21) is provided with a screw groove portion (21A), and the screw groove portion (21A) is screwed into the screw hole portion (19B) of the shaft hole (19A).

Further, a screw hole (19) C is provided at a lower edge portion of the shaft tube (19) of the fixing piece (17), and a spindle pin (21) fitted into the shaft tube (19). Is fastened with a screw (22) through the screw hole (19) C to fix the spindle pin (21) so as not to loosen. In this way, the shaft pin (21) in which the shaft tube (19) of the fixed piece (17) is fitted and fixed in the shaft hole (19A) is attached to the shaft hole (20) of the movable piece (18). The hinge (16) is constructed by being fitted to 20A).

To attach the door (5) to the door frame (4) using the hinge (16) having the above structure, as shown in FIG. 4, the fixed piece (17) and the movable piece (18) of the hinge (16) are attached. Attach the fixed piece (17) to the door frame (4) side and the movable piece (18) to the door (5) side with the screws (23, 24) through the screw holes (17A, 18A) of). In this way, to remove the door (5) attached to the door frame (4) by the hinge (16), the screw hole of the shaft tube (19) of the fixing piece (17) of the hinge (16) ( 19) Remove the screw (22) from C and fit a screwdriver (not shown) into the driver groove (21C) of the head (21B) of the spindle pin (21) as shown in Fig. 4. The support shaft pin (21) is pulled out from the shaft hole (19A) of the shaft tube (19) of the fixing piece (17) of the hinge (16).

When the support shaft pin (21) is thus pulled out from the shaft hole (19A) of the shaft tube (19) of the fixing piece (17) of the hinge (16), as shown in FIG. (5) can be removed from the door frame (4) together with the movable piece (18) of the hinge (16). In this case, when the door (5) is removed, the upper end of the door (5) does not interfere with the building body (2) or the casing of the door frame (4).

Other than the above embodiments, the spiral groove portion (21A) of the support shaft pin (21) is not essential, and the support shaft pin (21) may be fixed only by the screw (22). A notched flat portion may be provided at the contact portion of the shaft pin (21) with the screw (22).

[0012]

[Effect of device]

 Therefore, in the present invention, the door can be easily removed from the door frame without being interfered with by the building body or the like.
