SUMMARY OF THE INVENTION The present invention relates to a hinge unit for mounting a door on a door mounting portion so that the door can be opened and closed on either side in the width direction of the door. It is characterized by including the following requirements in order to solve the above problems. Door-side hinge member: It is attached to a door-side attachment portion formed on the door. Attachment side hinge member: It is attached to the attachment side attachment portion formed on the door attachment portion. Mounting portion side bearing portion: formed on the mounting portion side hinge member. Door side bearing part: formed on the door side hinge member. Hinge shaft: It is slidable relative to the door side bearing portion in the axial direction, and the length of the protruding portion protruding downward from the door side bearing portion changes according to the amount of sliding. And
By inserting the protruding portion into the mounting portion side bearing portion so as to be removable from above, the door side hinge member and the mounting portion side hinge member are relatively rotatably coupled in the opening / closing direction of the door.

In the above structure, the hinge shaft is slidable with respect to the door side bearing portion, and the length of the protruding portion protruding downward from the door side bearing portion can be changed. Thereby, when the hinge shaft attached to the door-side hinge member is inserted into the bearing portion of the attachment-side hinge member, the hinge shaft can be slid upward to shorten the length of the protruding portion. It is not necessary to lift the door greatly, and the hinge shaft can be easily positioned.

The hinge unit may be provided with a stopper mechanism that regulates the sliding limit of the hinge shaft in the direction in which the length of the protrusion decreases. The sliding limit can be set, for example, at a position where the hinge shaft does not project from the door-side bearing portion, but can also be set at a position where the hinge shaft projects from the door-side bearing portion by a predetermined length. . In the latter case, by forming a slight protrusion,
This makes it easier to perform positioning when inserting the hinge shaft into the mounting portion side bearing portion.

The protruding portion of the lateral adjustment screw from the base member side hits the hinge member, thereby forming a gap corresponding to the protruding amount between the hinge member and the base member. Thereby, the position of the door in the lateral direction (for example, the width direction) can be adjusted according to the size of the formed void.

Further, the hinge unit may be constructed as follows. That is, the hinge shaft is provided on the door-side hinge member, and the lower end side thereof is removably inserted into the bearing portion formed on the attachment-side hinge member from above. As a result, the door-side hinge member and the attachment-side hinge member are relatively rotatably coupled in the opening / closing direction of the door. Next, a vertical adjustment stopper portion that regulates the amount of entry of the hinge shaft into the mounting portion side bearing portion is provided so as to be movable in the axial direction of the hinge shaft. Further, on the lower end side of the mounting portion side bearing portion, a vertical adjustment screw threaded portion formed along the axial direction of the hinge shaft is fixedly provided to the mounting portion side bearing portion.
Further, the vertical adjustment screw is screwed into the vertical adjustment screw screwing portion from the lower side, and the screwing amount is changed.
The relative position of the hinge shaft relative to the bearing portion is changed in the axial direction of the attachment portion side. Here, the position of the vertical adjustment stopper portion changes in the axial direction of the hinge shaft corresponding to the position of the vertical adjustment screw. With this configuration,
Since the entering amount of the hinge shaft with respect to the mounting portion side bearing portion changes, the vertical positions of the door side hinge member and the door can be adjusted.

The hinge system of the present invention using the above-mentioned hinge unit is constructed as follows. That is, the hinge unit is arranged at two positions in the height direction of the door with respect to the door and the door mounting portion, and the stopper mechanism described above is provided for each of them, and the stopper unit is provided for one of the hinge units. The hinge shaft slide limit specified by the mechanism is set at a position where the hinge shaft does not protrude from the door side bearing part.For the other hinge unit, the slide limit is that the hinge shaft moves from the door side bearing part. It is set at a position where it projects a predetermined length. With this, by inserting the hinge shaft of one of the hinge systems into the mounting portion side bearing portion while protruding from the door side bearing portion by a predetermined length, the hinge shaft can be positioned with respect to the mounting portion side bearing portion. Therefore, it is possible to easily perform the mounting work for the mounting portion of the door.
