DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art When a door is hinged to a door frame or the like, an appropriate gap must be formed between the door and the door frame in a closed state so that the door can be opened and closed smoothly. Therefore, when the door is mounted, or when the position of the door is disturbed after the mounting and the opening and closing cannot be performed smoothly, a hinge capable of finely adjusting the vertical position of the door is used.
No. 41180 discloses this. This hinge is 1
The shaft core is vertically movably inserted into a cylindrical bearing portion provided on each of the pair of blade plates, and, for example, a vertically movable auxiliary cylinder is interposed between the lower bearing portion and the shaft core. One end is supported by a piece slidably inserted into the bearing, and the other end is configured to face and support the end of the upper bearing. The piece is supported by the screw operating member so as to be displaceable in the axial direction in the bearing portion on the lower side, so that the auxiliary cylinder is displaced in the axial direction to change the position of the blade plate up and down.

[0003]

By the way, in the above-described hinge, fine adjustment can be performed relatively easily when a vertical displacement occurs due to the hanging of the door, but the width of the door is relatively small. The direction (left-right direction) cannot be adjusted at all.

An object of the present invention is to provide a hinge which can easily adjust the position of a door in the width direction.

[0005]

SUMMARY OF THE INVENTION The present invention relates to a hinge for attaching a door to a door attaching portion so as to be openable and closable on one side in the width direction of the door. In order to solve the problem, it is characterized by including the following requirements. Door side hinge member: Attached to the door side. Hinging member on the mounting part side: mounted on the door mounting part side. Hinge shaft: The hinge members are relatively rotatably connected in the opening and closing direction of the door. Corresponding hinge member holding portion: attached to at least one of the opposing surface of the door mounting portion facing the side surface of the door or the side surface of the door, and at least one of the door side hinge member and the mounting portion side hinge member (corresponding hinge member) Are arranged in an overlapping manner, and the angle of the corresponding hinge member is held so as to be changeable in the adjustment direction with the width direction of the door as the adjustment direction. Corresponding hinge member angle changing mechanism: The angle of the corresponding hinge member with respect to the corresponding hinge member holding portion is changed in the adjustment direction, and the angular position is maintained. Then, by changing the angle of the corresponding hinge member with respect to the corresponding hinge member holding portion, the door is displaced in the width direction with respect to the door mounting portion to adjust the position thereof.

According to the above-described structure, the angle of the corresponding hinge member is changed in the adjustment direction by the corresponding hinge member angle changing mechanism with the width direction of the door as the adjustment direction. The position of the door in the width direction (lateral direction) can be easily adjusted.

The corresponding hinge member angle changing mechanism converts a rotation operation portion for applying a rotation operation in both directions and a rotation operation force applied to the rotation operation portion into a force in the angle change direction of the corresponding hinge member. And a force conversion mechanism. Thereby, the position adjustment in the width direction of the door can be more easily performed by operating the rotation operation unit. Specifically, the corresponding hinge member angle changing mechanism is provided on the adjusting screw member as a rotation operation part and the corresponding hinge member, and is a force conversion mechanism for screwing the adjusting screw member to the corresponding hinge member in the thickness direction thereof. An adjusting screw threaded portion as a mechanism may be provided. According to this, by performing a rotation operation on the adjusting screw member, the corresponding hinge member is moved in the axial direction of the adjusting screw via the adjusting screw screw portion, and the angle of the corresponding hinge member is changed based on the movement. Easy to do.

The corresponding hinge member holding portion includes a receiving member disposed between the corresponding hinge member and the door or the door mounting portion, and a holding member disposed on the opposite side of the corresponding hinge member with respect to the receiving member. Can also be included. In this case, a predetermined amount of gap is formed between the receiving member and the holding member to allow the angle of the corresponding hinge member to be changed, and the corresponding hinge member has a female screw as an adjusting screw screwing portion. The hole is formed so as to penetrate in the thickness direction, while the pressing member does not allow passage of the adjusting screw member at a position corresponding to the adjusting screw member, and the rotation operating tool of the adjusting screw member is not inserted. Allowable screw operation holes are formed. In this case, as the adjusting screw member is rotated in the screw operation hole, the corresponding hinge member is moved in the axial direction via the adjusting screw screw portion while the movement of the adjusting screw member in the axial direction is prevented by the pressing member. By moving, the angle is changed. Thereby, the corresponding hinge member angle changing mechanism can be configured simply and compactly.

The corresponding hinge member can be arranged so as to extend in the direction of the plate surface from between the receiving member and the pressing member on the side where the hinge shaft is formed. Then, between at least one inner surface of the receiving member and the holding member and the plate surface of the corresponding hinge member facing the inner surface, formed on any one of them and protruding toward the other side. At the same time, it is possible to provide a rotation fulcrum for rotatably supporting the corresponding hinge member around a rotation axis substantially parallel to the hinge axis. Further, the female screw hole can be formed at a position separated from the corresponding hinge member by a predetermined distance from the rotation axis in a direction intersecting the rotation axis. In this case, on the receiving member side, the adjusting screw member is screwed into the female screw hole such that the end protrudes from the corresponding hinge member and comes into contact with the plate surface of the receiving member, and adjusts the amount of projection based on the rotation operation. Thus, the rotation angle of the corresponding hinge member about the rotation axis is adjusted. By forming the rotation fulcrum, it is possible to smoothly change the angle of the corresponding hinge member.

[0010] Specifically, the rotation fulcrum portion is substantially parallel to the hinge axis along at least one inner surface edge of the receiving member and the holding member on the side where the corresponding hinge member extends. It can be a formed ridge.

In the above construction, as the corresponding hinge member rotates around the rotation axis, the adjusting screw member also rotates around the rotation axis integrally therewith. Accordingly, a curved screw receiving surface corresponding to the movement locus of the end of the adjusting screw member can be formed at a position corresponding to the end of the adjusting screw member on the plate surface of the receiving member. Thereby, the movement of the corresponding hinge member and the adjustment screw member accompanying the angle change can be performed more smoothly.

The receiving member may have a concave shape in the thickness direction on the door side and a concave portion in which the side surface on the hinge shaft side is open. The corresponding hinge member is accommodated in the recess so that the hinge shaft-side end extends from the opening. The pressing member is disposed on the opposite side of the receiving member with the corresponding hinge member interposed therebetween. In this case, the receiving member, the corresponding hinge member, and the holding member can be connected and integrated with each other by a connecting member penetrating the receiving member, the angle of which is allowed to be changed in the concave portion of the corresponding hinge member. This allows the hinge to be made compact, and prevents the corresponding hinge member from falling off from between the receiving member and the pressing member due to the penetration of the coupling member.

Next, the corresponding hinge member holding portion may hold the corresponding hinge member so that the corresponding hinge member can be slid in the front-rear direction of the door. In this case, the corresponding hinge member is moved forward and backward with respect to the corresponding hinge member holding portion in the front-rear direction of the door, and a front-rear direction adjusting screw mechanism for holding the position is provided directly or separately to the corresponding hinge member holding portion and the corresponding hinge member. Can be provided so as to indirectly straddle through. Thereby, not only the width direction of the door but also the position adjustment in the front-back direction can be easily performed.

In the above construction, it is also possible to provide a recess in the receiving member and accommodate the corresponding hinge member therein. In this case, however, the recess has a side surface on the side opposite to the opening. Is closed to form an edge shield. Further, the holding member slides integrally with the corresponding hinge member in the front-rear direction of the door, and the edge opposite to the position where the hinge axis is located is bent back in the depth direction in the recess. Thus, a facing bent portion facing the edge shielding portion of the receiving member is formed. The front-rear direction adjusting screw mechanism penetrates the edge shielding portion of the concave portion, extends inward of the concave portion along the plate surface direction of the corresponding hinge member, and has a female screw formed at the distal end side of the opposed bending portion of the pressing member. An adjusting screw screwed into the hole and a stopper for preventing the adjusting screw from moving in the axial direction can be provided. As a result, the longitudinal adjustment screw mechanism can be simply and compactly configured.

When the receiving member, the corresponding hinge member and the pressing member are connected and integrated by the above-mentioned connecting member, for example, the connecting member is configured to slide integrally with the corresponding hinge member and the pressing member. On the other hand, the receiving member can be formed with an elongated through hole that allows the connecting member to penetrate and allows the connecting member to slide with respect to the receiving member. Thereby, the sliding movement of the door in the front-rear direction can be smoothly performed.

Next, the hinge shaft is provided on the hinge member on the door side,
The lower end side can be configured to be removably inserted from above into a mounting portion side bearing portion formed on the mounting portion side hinge member. In this case, by adding the following requirements, the hinge of the present invention also has a function of adjusting the position of the door in the vertical direction. Stopper portion: The stopper portion defines the amount of entry of the hinge shaft into the mounting portion side bearing portion and is provided so as to be movable in the axial direction of the hinge shaft. Vertical adjusting screw threaded portion: fixedly provided at the lower end side of the mounting portion side bearing portion with respect to the mounting portion side bearing portion, and formed along the axial direction of the hinge shaft. Up / down adjustment screw: screwed into the up / down adjustment screw threaded portion from below and changing the amount of screwing, thereby changing the relative position of the hinge shaft with respect to the mounting portion side bearing portion in the axial direction. The position of the stopper is changed in the axial direction of the hinge shaft corresponding to the position of the vertical adjustment screw, whereby the amount of entry of the hinge shaft into the bearing on the mounting portion is changed, and the hinge on the door side is changed. The vertical position of the member and the door can be adjusted.

On the other hand, a mounting-portion-side bearing portion is formed on the mounting-portion-side hinge member, a door-side bearing portion is formed on the door-side hinge member, and the hinge shaft is relatively moved in the axial direction with respect to the door-side bearing portion. It can be slidably provided. In this case, the length of the projecting portion of the hinge shaft projecting downward from the door-side bearing portion changes according to the sliding amount, and the projecting portion can be inserted into and removed from the mounting portion-side bearing portion from above. The door-side hinge member and the attachment-portion-side hinge member are relatively rotatably coupled in the opening and closing direction of the door. According to this configuration, 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. Because it is possible, it is not necessary to lift the door greatly, and thus the door can be easily attached.

In the hinge, a stopper mechanism may be provided for defining a sliding limit of the hinge shaft in a direction in which the length of the protrusion from the door-side bearing decreases. The sliding limit can be set, for example, at a position where the hinge shaft does not protrude 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, it becomes easier to perform positioning when the hinge shaft is inserted into the bearing portion on the mounting portion side.

Here, the stopper mechanism has a stopper portion integrally formed so as to protrude outward in the middle of the hinge shaft and an inner side of the door-side bearing portion at a position corresponding to the sliding limit of the hinge shaft. And a stopper receiving portion provided at the first position. In this case, the sliding movement of the hinge shaft with respect to the door-side bearing portion is stopped by the stopper portion abutting on the stopper receiving portion. Specifically, the stopper portion slides inside the door-side bearing portion together with the hinge shaft, and can be configured to be able to hold an arbitrary sliding position by friction generated between the outer surface thereof and the inner surface of the door-side bearing portion. . Further, the stopper receiving portion is a ring member concentrically arranged outside the hinge shaft in a state where the hinge shaft is allowed to slide with respect to the hinge shaft, and from the one end side with respect to the door-side bearing portion together with the hinge shaft. It can be configured to be inserted and fixed to the inside of the door-side bearing by friction generated between its outer surface and the inner surface of the door-side bearing. Thus, the stopper mechanism can be simply configured.

As shown in the figure, the hinge shaft 13 may be configured to protrude from the door-side bearing portion 8 by a predetermined length h 'at the upper limit position.

Hereinafter, the operation of the hinge 1 of the present invention will be described. First, as shown in FIG.
, The hinge shaft 13 is slid to the upper limit position. Here, in FIG. 14, the hinge 1 attached to the upper part of the door 2 is of the type shown in FIG.
The hinge shaft 13 does not protrude from the bearing portion 8 at the upper limit position, and the lower hinge 1 'is of the type shown in FIG. 16, that is, the hinge shaft 13 protrudes by a predetermined length h' at the upper limit position. Is used. The method of use is as follows. First, in the lower hinge 1 ′, the tip of the protruding hinge shaft 13 is inserted into the mounting portion side bearing portion 9, thereby positioning the hinge shaft 13 with respect to the mounting portion side bearing portion 9. I do. Then, in this state, the lower surface of the door-side bearing portion 8 and the upper surface of the mounting portion-side bearing portion 9 are aligned with each other on the upper hinge 1, and the hinge shafts 13 of both the hinges 1 (1 ′) are pushed down respectively.
