Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a hinge that allows a door attached to an opening frame or the like to be adjusted vertically and widthwise.

[Conventional technology]

For opening frames such as entrances and exits, one opening door or two can be attached via a hinge as a double door. However, this hinge consists of a hinge piece that is screwed to the fixed side of a pillar or stile, and a hinge piece that has the same shape as this hinge piece that is screwed to the door side, with their boss parts intertwined with each other. At the same time, a shaft is inserted through this boss portion to form a single unit.

[Problem to be solved by the invention]

Even if hinges with various designs are formed using the desired material such as stainless steel, brass, iron or aluminum alloy, the thickness of each hinge piece is cut out between the stile and door. It is secured with a screw, so the position of the hinge attached to the stile cannot be adjusted later - the notch for embedding the hinge pieces on the stile and door side must be set accurately to match the mounting position. For this reason, the installation of the door is time-consuming and requires skill.The present invention allows the door to be installed vertically and widthwise without changing the position of the hinge piece embedding notch provided in advance on the stile or door side. The purpose is to make it adjustable in the direction.

[Means to solve the problem]

The present invention has been made to achieve the above object, and the hinge piece attached to the stile is held between a fixed plate, and the hinge piece is moved up and down by a cam with respect to the fixed plate screwed to the stile. At the same time, the hinge piece attached to the door side is fixed to the door via an adjustment plate that is retractably provided with a rack, and the rack is engaged with the pinion provided on the hinge piece, and the hinge piece is moved in and out by rotation of the pinion.
The gist is that the width of the door can be adjusted by increasing or decreasing the distance between the adjustment plates. [Function] A long hole in the vertical direction is provided in the hinge piece attached to the stile.
In order to fix the fixing plate by inserting it into the long hole and fixing it by pressing the screw on the fixing plate, the entire hinge can be moved up and down by rotating the cam provided on the hinge piece within the range of this long hole. The hinge can be moved in the vertical direction, and the mounting hinge can be adjusted vertically within the recess made in the stile.Furthermore, the hinge piece attached to the door side has an adjustment plate fixed with screws on the back side.
A pinion provided on the hinge side is rotated between this hinge piece and an adjustment plate fixed to the door with screws, and the latch is moved in and out to make adjustments, thereby also adjusting the door in the lateral direction. This allows you to accurately adjust and secure the hinge installed between the door and the hinge without changing the installation. [Embodiments] The present invention will be explained below based on illustrated embodiments.

In the figure, A is a hinge, which is composed of two hinge pieces 1 and 2, a shaft 3, a fixing plate 4, and an adjusting plate 5.

One hinge piece 1, which is attached to a pillar or an opening frame with screws, is formed into a flat plate shape with the adjustment width H shorter than the length in the height direction of the other hinge piece 2, which is attached to the door side.

In this case, the boss portion of each hinge piece is As long as they are intertwined with each other and their axes coincide so that they can pass through the shaft, the shape of the boss portion is not limited to that shown in the drawings. When passing the shaft 3 between the boss parts 12 and 22, a bush B is formed of synthetic resin or other material on the mutually contacting surfaces of the boss parts so that both hinge pieces 1 and 2 can swing smoothly. (or washers) are interposed, and the boss portions at the upper and lower ends of the shaft are sometimes closed with caps C fitted to prevent the shaft from coming off.

The fixing plate 4 is formed into a flat plate 41 whose width is equal to that of the hinge piece 1.2 and whose length in the height direction is equal to that of the hinge piece 2 on the door side. At this time, a plurality of countersunk screw holes 43 are drilled to match the slotted holes 3, and a stepped cam fitting hole 44 is drilled at a position where the cam 6 having the desired shape fits into the cam fitting groove 14. The outer periphery of this hole 44 is provided with a scale 45 for displaying the amount of adjustment in the vertical direction of the hinge by rotation of the cam.
