[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinge unit for attaching a door to a door mounting portion such as a door frame, and a hinge system using the same.

[0002]

2. Description of the Related Art Conventionally, a hinge for attaching a door to a door frame has, for example, a hinge shaft integrally formed on a hinge plate attached to the door side, and the hinge shaft is attached to a bearing portion of the hinge plate attached to the door frame side. In most cases, when the hinge shaft is inserted, both hinge plates are relatively rotatably connected to each other by the hinge shaft to open and close the door.

[0003]

In the above-described hinge, a hinge shaft projects downward from a hinge plate attached to the door, and the hinge shaft is inserted into a bearing of the hinge plate on the door frame. Must lift the door so that at least the tip of the hinge shaft is located near the opening of the bearing. In this case, since the hinge shafts of the hinges attached along the height direction of the door need to be simultaneously dropped into the corresponding bearings, there is a disadvantage that the positioning operation is very difficult to perform. Further, there is a problem that labor is required because the state in which the door is lifted for positioning continues for a long time.

An object of the present invention is to provide a hinge unit and a hinge system using the hinge unit, in which the operation of inserting the hinge shaft into the bearing portion is simple and labor can be saved.

[0005]

SUMMARY OF THE INVENTION The present invention relates to a hinge unit for mounting a door on a door mounting portion so as to be openable and closable on one side in a width direction of the door, In order to solve the above-mentioned problem, the following requirements are included. Door side hinge member: mounted on a door side mounting portion formed on the door. Attachment-side hinge member: attached to the attachment-side attachment portion formed at the door attachment portion. Mounting part side bearing part: formed on the mounting part side hinge member. Door side bearing part: formed on the door side hinge member. Hinge shaft: The hinge shaft is slidable relative to the door-side bearing in the axial direction, and the length of the protrusion protruding downward from the door-side bearing changes according to the amount of sliding. And
By inserting the protruding portion into the mounting portion side bearing portion so as to be able to be inserted and removed from above, the door side hinge member and the mounting portion side hinge member are relatively rotatably coupled in the opening and closing direction of the door.

In the above configuration, the hinge shaft is slidable with respect to the door-side bearing, and the length of the protrusion protruding downward from the door-side bearing can be changed. Thereby, when inserting the hinge shaft attached to the door-side hinge member into the bearing portion of the attachment-side hinge member, the hinge shaft can be slid upward to reduce the length of the protruding portion. There is no need to lift the door significantly, and the hinge shaft can be easily positioned.

[0007] In the hinge unit, a stopper mechanism for defining a sliding limit of the hinge shaft in a direction in which the length of the protruding portion decreases can be provided. The sliding limit can be set, for example, at a position where the hinge shaft does not protrude from the door-side bearing, but can also be set at a position at which the hinge shaft projects a predetermined length from the door-side bearing. . In the latter case, by forming a slight protrusion,
Positioning when the hinge shaft is inserted into the mounting portion side bearing portion can be more easily performed.

The stopper mechanism includes a shaft-side engaging portion formed on the hinge shaft side, and a bearing-side engaging portion formed on the inner surface side of the door-side bearing portion and engaging with the shaft-side engaging portion. Can be configured. Further, a door-side sleeve that covers the hinge shaft between the hinge shaft and the door-side bearing portion and slides integrally with the hinge shaft can be provided for a portion of the hinge shaft that slides in the door-side bearing portion. . The shaft-side engaging portion can be formed on the outer surface of the door-side sleeve.

The door-side bearing can be formed in a cylindrical shape, and the door-side sleeve can also be formed in a corresponding cylindrical shape. In this case, a cut from the outer surface to the inner surface is formed in the cylindrical door side sleeve on one side in the axial direction along the axial direction, and further in the axial direction on the opposite side to the cut. A folded portion can be formed along. Then, the door-side sleeve can be attached to the hinge shaft from the direction intersecting the axis thereof, with the folded portion being opened on both sides from the cut.

[0010] The hinge unit may be constructed as follows. That is, a base member is disposed on the door-side mounting portion or the mounting portion-side mounting portion corresponding to at least one of the hinge members, and a fixing member is fixed to the mounting portion through the hinge member and the base member. Thus, the hinge member is fixed to the mounting portion together with the base member. Further, a lateral adjustment screw thread is formed on the base member,
The lateral adjustment screw is screwed into this. The lateral adjustment screw forms a gap between the hinge member and the base member according to the amount of protrusion when the protruding portion from the base member side hits the hinge member. This makes it possible to adjust the position of the door in the lateral direction (for example, in the width direction) according to the size of the formed gap.

Further, the hinge unit can be configured as follows. That is, the hinge shaft is provided on the door-side hinge member, and its lower end is removably inserted from above into a bearing formed on the attachment-side hinge member. Thus, the hinge member on the door side and the hinge member on the attachment portion are relatively rotatably coupled in the opening and closing direction of the door. Next, an up / down adjustment stopper portion that regulates the amount of entry of the hinge shaft into the mounting portion side bearing portion is provided movably in the axial direction of the hinge shaft. At the lower end side of the mounting portion side bearing portion, a vertically adjusting screw threaded portion formed along the axial direction of the hinge shaft is fixedly provided to the mounting portion side bearing portion.
Furthermore, the upper and lower adjustment screws are screwed into the upper and lower adjustment screw screw portions from below, and by changing the screwing amount,
The relative position of the hinge shaft to the bearing portion in the axial direction on the mounting portion side is changed. Here, the position of the vertical adjustment stopper is changed in the axial direction of the hinge shaft in accordance with the position of the vertical adjustment screw. With this configuration,
Since the amount of entry of the hinge shaft into the mounting portion side bearing portion changes, the vertical position of the door side hinge member and the door can be adjusted.

The hinge system of the present invention using the above-described hinge unit is configured as follows. That is, the hinge unit is disposed at two positions along the door height direction with respect to the door and the door mounting portion, and the above-described stopper mechanism is provided for each of the hinge units, and a stopper is provided for one of the hinge units. The sliding limit of the hinge shaft defined by the mechanism is set at a position where the hinge shaft does not protrude from the door-side bearing, and for the other hinge unit, the sliding limit is such that the hinge shaft is moved from the door-side bearing. The position is set at a position protruding a predetermined length. Thus, by inserting the hinge shaft of one hinge system into the mounting portion side bearing portion in a state of protruding from the door side bearing portion by a predetermined length, positioning of the hinge shaft with respect to the mounting portion side bearing portion can be performed. Since it is possible, the work of mounting the door on the mounting portion can be easily performed.
