Description

  The present invention relates to a door hinge mechanism provided at an entrance of a building or an entrance of a room.

  Revolving doors provided at the entrances of buildings and rooms are pivoted through hinge mechanisms between fixed materials such as pillars and walls and the doors, and are installed so that they can be opened and closed. For example, as shown in FIG. 1, the hinge mechanism is provided with support shafts or bearings on upper and lower fixed frame side mounting plates, and upper and lower door side mounting plates with bearings or support shafts. Is fitted to the bearing so as to be rotatable, and the door is opened and closed.

  Further, such a door hinge mechanism requires that the door be correctly assembled at a desired position of the fixed frame, and that the support shaft or the bearing has a front-rear direction (door thickness direction) and a left-right direction (door width direction). Or a position adjustment mechanism that can finely adjust the position in the vertical direction (the height direction of the door) is disclosed in JP-A-9-203260, JP-A-9-209441, and JP-A-2006. -169817.

  However, the position adjustment mechanism described in the above publication has two directions on the front side and the side of the door body by using a left-right adjustment screw and a front-rear adjustment screw mounted on the adjustment mechanism. Therefore, the adjustment work is difficult because the work is performed by changing the place and direction, and the work is usually performed in a narrow place. Moreover, it becomes an irregular work in a narrow space where tools are difficult to enter, and the workability is poor.

  Therefore, in Japanese Patent Application Laid-Open No. 2006-274570, a left-right adjustment screw and a front-rear adjustment screw are arranged in the same direction on either the front side or the side surface of the door body, and the left-right adjustment screw and the front-rear direction from one direction. There has been proposed a door hinge mechanism that adjusts from one direction on the front side or side of the door with an adjusting screw.

A fitting insertion hole that rotatably supports the support shaft disposed in the first support plate, the fitting insertion hole is exposed in the fitting window formed in the one support plate, and is inserted in a non-rotatable manner in the vertical axis direction. A bearing block to be supported, and a bearing case disposed so as to be movable in the width direction of the door between the support plates in a U-shaped plane that fits along the left and right side wall surfaces and the rear wall surface of the bearing block; A front / rear direction adjusting screw that is vertically movable along one side wall and a rear wall of the bearing case and is vertically installed on the bearing case, and a left / right direction adjusting screw that is provided between the pair of upper and lower support plates. Front / rear direction adjustment member screwed into each And a preliminary lateral direction adjusting member,
A protrusion formed on the front-rear direction adjusting member is formed into a longitudinally elongated hole formed in the side wall of the bearing case and a groove extending obliquely on the side wall surface of the bearing block so as to cross the longitudinally elongated hole obliquely. The protrusions that are inserted and formed in the left-right adjustment member are inserted into oblique long holes formed in the oblique direction formed in the rear wall of the bearing case and exposed to one of the pair of upper and lower support plates, respectively. The position of the bearing can be adjusted to the front, rear, left and right by rotating the front and rear direction adjusting screw and the left and right direction adjusting screw to move the bearing block on the door side mounting plate front and rear and right and left.

  According to the present invention, when the front / rear direction adjusting screw exposed on the support plate is rotated, the front / rear direction adjusting member in which the protrusion is inserted into the groove extending in the oblique direction formed on the side wall surface of the bearing block moves up and down. The bearing block moves independently in the front-rear direction (width direction) of the door. When the left-right adjustment screw exposed on the support plate is rotated, the bearing case moves in the left-right direction (thickness direction) together with the bearing block.

  Further, in the above-mentioned invention, the internal thread formed in the bearing block through which the fitting insertion hole of the support shaft provided in the fixed side mounting plate is formed so as to penetrate from the bottom surface to the top surface and is engraved above the fitting insertion hole. A vertical adjustment screw that comes into contact with the support shaft from above is screwed, and an operation portion of the vertical adjustment screw is provided on one support plate that exposes the front-rear direction adjustment screw and the left-right direction adjustment screw. A transparent window to be exposed is formed, and the front-rear direction adjusting screw, the left-right direction adjusting screw, and the vertical direction adjusting screw are exposed on the one support plate, and the front-rear, left-right, and vertical directions of the support shaft are exposed from the one support plate side. The adjustment operation can be performed from the same direction.

  According to the present invention, the front and rear direction adjusting screws and the left and right direction adjusting screws exposed on the support plate are operated from the side of the support plate that is exposed in one direction, so that the bearing block is moved in the thickness direction and the width direction of the door. Since the bearing position can be adjusted by moving it independently, the operability is excellent. Moreover, the height adjustment can be adjusted from the same direction by exposing the longitudinal adjustment screw together with the longitudinal adjustment screw and the lateral adjustment to the support plate.
