Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a hinge for attaching a door attached to an opening or the like of a building.

[Prior Art] In a conventional hinge, left and right blades are rotatably connected by a shaft, and each blade has a plurality of mounting holes.

The hinge as described above fixes one wing piece to a frame made of wood or the like, which is fixed to the opening of the building, with wood screws or the like, and the other wing piece is fixed to the side surface of the door with wood screws or the like.

In installing the door with such a hinge, it is aesthetically desirable to maintain a constant gap between the upper edge of the door and the upper frame of the frame and between the lower edge of the door and the lower frame (floor surface) of the frame. Of course, it is important not only for the above, but also for opening and closing the door smoothly.

Therefore, careful attention is required when installing the door,
In addition, the work requires skill.

[Problems to be solved by the device]

The conventional attachment of the door by the hinge as described above has a problem in that careful attention is required to maintain a constant gap above and below the door and a high degree of skill is required.

In addition, when correcting the clearance after installing the door, the screwing position of the removed wood screw is close to the front wood screw screw hole, so the support capacity of the wood screw is significantly reduced, and the work of filling with wood plugs of the screw hole etc. There was also a problem that was necessary.

Therefore, an object of the present invention is to provide a hinge in which the gap between the upper and lower edges of the door can be corrected very easily after mounting the door.

[Means for Solving the Problems]

In order to achieve the above object, the present invention provides a hinge in which left and right mounting vanes are rotatably connected by a shaft, and a first tubular portion arranged in series at both ends of opposite edges of both vanes,
The second tubular portion is provided in the other central portion so as to fit between the first tubular portions, and the opposite tubular portions are provided with second tubular portions so as to form a predetermined gap. A step portion externally contacting the end surface of the second tubular portion and a second external portion of the second tubular portion are provided at opposite ends of a screw shaft that is provided with a screw portion and is screwed into each of the first tubular portions so as to be rotatable from the outside. It is configured by providing a protruding shaft that fits into the end.

[Action]

This invention has the above-mentioned structure. To explain the operation thereof, first, the vanes are attached to the door frame and the door via wood screws or the like.

To increase the gap between the lower edge of the installed door and the lower frame of the door frame, first engage a tool such as a screwdriver on the lower screw shaft, and then rotate it in one direction while rotating the lower screw. The shaft is moved downward by a predetermined length.

Then, a tool such as a screwdriver is engaged with the upper screw shaft, and the screw shaft is moved downward while rotating in one direction, whereby the stepped portion of the upper screw shaft and the second tubular portion are moved. The door ascends together with the blade having the first tubular portion due to the contact with the upper edge of the door.

To reduce the gap between the lower edge of the door and the lower frame of the door frame, first engage a tool such as a screwdriver on the upper screw shaft, and then rotate it in the other direction to move the upper screw shaft upward. And move it for a predetermined length.

Next, when a tool such as a screwdriver is engaged with the lower screw shaft and the lower screw shaft is moved upward while rotating in the other direction, the step portion of the lower screw shaft is moved to the second position. The door descends together with the blade having the first tubular portion by contact with the lower edge of the tubular portion.

〔Example〕

Hereinafter, an embodiment according to the present invention will be described with reference to the accompanying drawings.

In the figure, reference numerals 1 and 2 denote a pair of left and right mounting blades, and the first and second blades 1 and 2 are arranged in series at both ends of opposite edges of the blades 1 and 2.
The tubular portions 3 and 3 are provided in the other central portion thereof with a second tubular portion 4 which is fitted between the first tubular portions 3 and 3 and forms a predetermined gap at the opposite ends. .

A screw portion 5 is provided on the entire inner circumference of both the first tubular portions 3 and 3, and a screw shaft 7 having a tool engaging portion 6 at the end is screwed into the screw portion 5.

Further, an annular step portion 8 that abuts on the end edge of the second tubular portion 4 and a protruding shaft 9 that is fitted into the second tubular portion 4 are provided at the tips of the screw shafts 7, 7. ing.

Reference numeral 10 is a plurality of mounting holes for inserting wood screws provided on both blades 1 and 2, 11 is a screwdriver screwed into the first tubular portions 3 and 3, and this screwdriver 11 is removed when the screw shaft 7 is rotated. Install after operation. Reference numeral 12 denotes a tubular cover fitted to the outside of the second tubular portion 4 by bringing the end surfaces into contact with the opposing ends of both the first tubular portions 3 and 3.
The cover 12 is provided with a slit 13 into which a connecting portion between the blade 2 and the second tubular portion 4 is fitted.

The hinge configured as described above fixes the vane 1 to the door and the vane 2 to the door frame with wood screws, respectively.

To increase the gap between the lower edge of the mounting door and the lower frame of the door frame, first engage a tool such as a screwdriver with the engaging portion 6 of the lower screw shaft 7 and then rotate in one direction. The lower screw shaft 7 is moved downward by a predetermined length.

Next, a tool such as a screwdriver is engaged with the engaging portion 6 of the upper screw shaft 7, and the upper screw shaft 7 is moved downward while rotating in one direction. Due to the contact between the portion 8 and the upper edge of the second tubular portion 4, the door rises together with the blade 1 having the first tubular portion 3.

As a result, the gap between the lower edge of the door and the lower frame of the door frame becomes large.

After adjusting the gap, the lower screw shaft 7 is rotated in the other direction so that the step portion 8 of the lower screw shaft 7 is brought into contact with the lower edge of the second tubular portion 4. .

Also, when the upper screw shaft 7 is rotated in the other direction and then the lower screw shaft 7 is rotated in the other direction, the door descends and the gap between the lower edge of the door and the lower frame of the door frame is reduced. Get smaller.

〔effect〕

As described above, according to the hinge according to the present invention, the door can be raised or lowered by an extremely simple operation of rotating the screw shafts in the first cylindrical portions located above and below.
After the door is attached, the gap between the lower edge of the door and the lower frame of the door frame can be adjusted.

Therefore, the installation work can be performed very easily without requiring any skill to install the door.
