Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a door hinge attaching/detaching tool for attaching a door to a door frame, pillar, etc. so as to be openable and closable.

[Prior Art and its Problems] Conventionally, door hinge attachment/detachment tools have been a hinge piece with a through hole provided at the tip, as in the hinge described in Japanese Utility Model Application Publication No. 50-84671, for example. A fixing body is known in which the tip of the hinge piece is forcefully pushed in and has a stopper that fits into the through hole to prevent it from coming off.

However, in conventional door hinges, the corners of the plate for attaching to and detaching from the fixed body are all formed into curved edges.

Therefore, if you want to attach two upper and lower hinges to a door and lock them to the locking members provided on the door frame or pillar, you must attach both the upper and lower hinges at the same time, and also hold the locking member with the door vertical. The door cannot be inserted unless it is inserted into the locking material, and even if a portion of either the upper or lower hinge is inserted into the locking material first, the corner is curved, so it is dangerous as the door may slide off. Not only that, but it is difficult to precisely match the removable plates of the two upper and lower hinges at a predetermined angle, and the door is relatively heavy.
It is difficult for one person to hold the door vertically and simultaneously lock the upper and lower hinge plates to the upper and lower locking members, resulting in the problem of requiring time and manpower. Furthermore, in recent years, it has become common for doors and door frames to be transported in an assembled state, removed from the door frame at a construction site, fixed to the house, and then reattached to the door frame. In such cases, the door and door frame will have to be attached and detached several times, and if the above-mentioned labor and labor are required each time, even if we try to reduce costs by producing building components in a factory, it will not be possible to do so. There were also problems in that it led to high assembly costs and went against the labor-saving goal.

[Purpose and outline of the invention] The purpose of the invention is to solve the above-mentioned conventional problems and to obtain a door hinge attachment/detachment tool that allows one person to easily attach and detach a door and a door frame, etc. A fixed plate that is fixed to the door and a detachable plate that is attached to and detached from a structure such as a door frame or pillar are pivotally connected, and a locking hole is drilled in the detachable plate of the door hinge. It has a door hinge with a step formed at the corner and a locking protrusion that is fitted into the locking hole of the detachable plate, and has a notch on three sides around the locking protrusion excluding the insertion side of the detachable plate. The present invention is characterized by comprising a removable plate locking member fixed to the structure, the locking protrusion being elastically biased.

[Example] Hereinafter, an example of the door hinge attaching/detaching device according to the present invention will be described based on the drawings.

Fixing plate 3 fixed to door 1 with screws 2
and a removable plate 5 that is attached to and detached from a structure 4 such as a door frame or a pillar. At a hinge A pivoted by a shaft 6, the upper and lower edges of the removable plate 5 are attached to the corners of the rotating end of the detachable plate 5. Step portions 7, 7 parallel to are formed, and
A locking hole 8 is bored in the center of the detachable plate 5 near the rotation end.

On the other hand, in the structure 4, a groove 9 having a depth approximately equal to the thickness of the detachable plate 5 is formed over the range into which the detachable plate 5 is inserted, and within the groove 9, the detachable plate 5 is inserted. When the locking hole 8 is
A removable plate locking member B having a locking protrusion 10 sized to fit into the locking hole 8 is fixed with screws 12 .

The locking protrusion 10 of the detachable plate locking material B is formed in a triangular shape on the side so that the height gradually increases from the insertion side of the detachable plate 5. Approximately trapezoidal notches 13 are provided on three sides except for the insertion example, and the locking protrusion 10 is elastically biased, and the insertion side of the detachable plate 5 is inclined so as to be gradually lowered from the groove 9. An insertion guide 14 is formed on the back surface of the locking protrusion 10.
When the locking protrusion 10 is removed from the locking hole 8, a stepped portion 15 is formed as a hook for a tool (not shown) such as a screwdriver.

In the figure, 16 and 17 are screw holes.

[Operation] The door hinge attachment/detachment devices A and B configured as described above are attached and detached as follows.

For example, as shown in FIGS. 2 and 4, fixing plates 3 of a pair of hinges A (one omitted) are fixed to the top and bottom of the door 1 with screws 2, and the plates 3 are attached to a structure 4 such as a door frame. The locking member B is fixed with screws 12.

Next, while holding the door 1 and inserting the stepped portion 7 of the removable plate 5 of the lower hinge A, and the tip of the removable plate 5 between the structure 4 and the insertion guide 14, temporarily attach the removable plate locking member B. After placing the removable plate 5 of the upper hinge A on the end of the groove 9, insert the insertion end of the removable plate 5 of the upper hinge A from between the opposing removable plate locking member B and the structure 4, and then insert the removable plate 5 of the upper and lower hinge A. 5 from between the opposing detachable plate locking material B and the structure 4, and then insert the detachable plate 5 of the upper and lower hinges A into the groove 9 of the detachable plate locking material B and the structure 4 at the same time. insert the locking material B into the locking hole 8 of each removable plate 5.
The hinge A is fitted into the locking protrusion 10 to fix the hinge A to the removable plate locking member B.

Here, when the removable plate 5 is inserted between the groove 9 and the structure 4, the tip edge of the removable plate 5 abuts the locking projection 10, but a notch 13 is formed around the locking projection 10. and is elastically biased, the detachable plate 5
is inserted against the elasticity of the locking projection 10, and does not interfere with the engagement between the locking hole 8 and the locking projection 10.

When releasing this engagement, insert the tip of a screwdriver or the like into the notch 13 from the back side of the removable plate locking member B, hook the tip of the screwdriver or the like on the stepped portion 15, and hold the locking hole 8. By tilting the screwdriver in the direction in which the locking protrusion 10 is released, the hinge A is removed from the detachable plate locking member B.

[Effects] Since the present invention is configured and used as described above, it is possible to easily attach and detach the door to structures such as door frames and pillars, and in particular, there is a step at the corner of the insertion end of the hinge. If a pair of upper and lower hinges are attached to a door, the stepped part of the removable plate of either the upper or lower hinge can be connected to the insertion end of the removable plate locking material or to the door. Once placed on the edge of the space formed by a structure such as a frame or pillar and the removable plate locking material, the removable plate of the other hinge can be inserted into the removable plate locking material. To easily attach and detach a heavy door to a structure such as a door frame or pillar by one person, to improve the working pillar, to help save labor, and to reduce costs.

In addition, as shown in the example, in the case where the detachable plate locking material is a detachable plate locking material in which the insertion side of the detachable plate is sloped low and an insertion guide is formed, it can be attached to a door frame or a pillar, etc. The insertion opening for the hinge removable plate can be made as wide as possible without forming a special notch in the structure, making it easier to insert the removable plate and making it easier to lock the removable plate locking material. In the case where the protrusion is a locking protrusion with a step on its back surface,
By applying a tool such as a screwdriver to the locking protrusion and tilting the locking protrusion in the direction in which it is removed from the locking hole, the hinge can be easily removed from the detachable plate locking member.
