Description

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

A door provided at an entrance of a building, an entrance of a room, and the like is pivotably attached via a hinge mechanism between a fixing material side such as a pillar or a wall and the door, and can be opened and closed.
In this type of door hinge mechanism, for example, a support shaft or a bearing is provided on the upper and lower fixing material side mounting plates, and a bearing or a support shaft is provided on the upper and lower door side mounting plates. The combined door is pivotable.

  Further, for the purpose of correctly incorporating the door into a desired position on the fixing material side, the position of the support shaft or the bearing in the front-rear direction, left-right direction, or up-down direction can be finely adjusted in the door hinge mechanism. Japanese Patent Application Laid-Open No. 9-203260 and Japanese Patent Application Laid-Open No. 9-209641 are provided with a position adjusting mechanism.

  However, since the position adjustment mechanism described in the above publication is a method of adjusting the position of the support shaft from two directions of the front side and the side surface with an adjustment screw attached to the adjustment mechanism, Adjustment work is difficult due to the work done by changing the direction and usually working in a narrow space. In some cases, the door is removed several times. Moreover, it becomes an irregular work in a narrow space where tools are difficult to enter, and the workability is poor.

Japanese Utility Model Laid-Open No. 59-62169 discloses a position adjusting mechanism using an eccentric cam that can adjust the longitudinal and lateral positions of the axis of the support shaft from one direction. However, in the position adjustment using the eccentric cam described in the publication, the position adjustment shaft is restricted by the locus drawn by the eccentric cam, and it is difficult to accurately adjust the mounting position of the door.

  The present invention is intended to solve the above-described problems, and provides a door hinge mechanism that facilitates adjustment of the door mounting position, improves the adjustment work, and allows the door to be mounted at a desired position. It is intended to provide.

  According to the door hinge mechanism of the first aspect of the present invention, a support shaft is provided on the upper and lower fixing material side mounting plates, a bearing is provided on the upper and lower door side mounting plates, and the support shaft is fitted to the bearing. In the hinge mechanism of the door that can be rotated, an attachment position adjustment mechanism for adjusting the attachment position of the door is provided on the door-side attachment plate provided with the bearing, and the adjustment mechanism includes at least A front-rear direction adjustment member and a left-right direction adjustment member are provided, and the front-rear direction adjustment member is formed with a left-right direction long hole and an adjustment screw is attached, the front-rear direction adjustment member is moved in the front-rear direction by the adjustment screw, The left-right adjustment member is formed with an oblique long hole and an adjustment screw is mounted. The left-right adjustment member is moved in the front-rear direction by the adjustment screw, and the left-right direction long hole and the oblique long hole intersect. The bearing is mounted on the part And wherein the are.

  According to a second aspect of the present invention, the adjusting screw mounted on the front-rear direction adjusting member and the adjusting screw mounted on the left-right direction adjusting member are arranged on the left and right sides of the one surface of the attachment position adjusting mechanism.

  According to a third aspect of the present invention, the adjusting screw mounted on the front-rear direction adjusting member and the adjusting screw mounted on the left-right direction adjusting member are arranged above and below one surface of the attachment position adjusting mechanism.

  According to a fourth aspect of the present invention, an adjustment screw for adjusting the depth of the bearing is attached to the bearing attached to the lower attachment position adjusting mechanism.

  The present invention has the following effects. According to the first aspect of the present invention, the front-rear direction adjusting member is moved in the front-rear direction by the adjustment screw that is movable in the front-rear direction, but the movement of the bearing is restricted by the oblong slot formed in the left-right direction adjusting member. The position in the front-rear direction is finely adjusted by moving in the direction. That is, the position of the door in the Y-axis direction is adjusted and determined by adjusting the bearing in the front-rear direction.

  On the other hand, if the bearing is adjusted by moving the left-right adjustment member in the front-rear direction with the adjustment screw, it tries to move along the oblique long hole, but the movement is restricted by the left-right long hole and moved in the left-right direction. The horizontal position is adjusted. That is, the position of the door in the X-axis direction is adjusted.

Therefore, it is possible to improve the installation position adjustment work by avoiding the door installation position adjustment performed by removing the door several times due to the difficulty of work and the work in a narrow space where tools are difficult to enter.
Since the adjustment in the front-rear direction and the left-right direction is individually performed by the front-rear direction adjustment member and the left-right direction adjustment member and adjusted to an arbitrary position, an accurate positioning operation is performed.
Incidentally, in the position adjustment using the eccentric cam, the position adjustment axis is restricted by the locus drawn by the eccentric cam, and it is difficult to precisely fine-tune to an arbitrary mounting position.

  According to the second aspect of the present invention, since the adjustment screws are arranged on the left and right sides of one surface of the attachment position adjusting mechanism, the adjustment is performed from one direction, that is, from the front side, and the work is improved. Therefore, it is possible to improve the installation position adjustment work by avoiding the door installation position adjustment performed by removing the door several times due to the difficulty of work and the work in a narrow space where tools are difficult to enter. In addition, since the arrangement structure of the adjusting screws on the same surface arranged on the left and right is reduced, the front-rear direction adjusting member and the left-right direction adjusting member are expected to be thinned, and the member can be pressed and the cost can be reduced.

  According to the invention of claim 3, since it is performed with the screws arranged above and below one surface of the attachment position adjusting mechanism, the adjustment is performed from one direction (front side), and the work is similarly improved. Further, in this case, since the screw arrangement structure is provided on the same vertical surface arranged above and below, the left and right widths of the front-rear direction adjusting member and the left-right direction adjusting member are reduced, and the hinge mechanism is expected to be downsized.

  According to the invention of claim 4, the depth (depth) of the bearing is changed by operating the adjusting screw, the vertical position of the bearing is moved, and the position in the Z-axis direction is adjusted. Therefore, in combination with the previous item, the position of the door in the three directions of the Y axis, the X axis, and the Z axis is adjusted.

  Embodiments of the present invention will be described below with reference to the drawings.
