In the conventional hinge having the adjusting screw a as described above, when the amount of rotation of the connecting member c increases, the position of the connecting member c can be smoothly adjusted by the adjusting screw a. There was a problem that it became impossible. That is, the surfaces a ₃ , a ₃ of the holding portions a ₂ , a ₂ facing the connecting member c are planes orthogonal to the axis of the adjusting screw a. Assume that the connecting member c is now in surface contact with the opposing surfaces a ₃ and a ₃ . In this state, when the adjusting screw a is moved upward to rotate the connecting member c in the direction of the arrow in FIG. 12, the adjusting screw a is linearly displaced, whereas the connecting member c is rotationally displaced. c is bent at the contact point b of the clamping portion a ₃ of the lower, downward force is applied to the contact points b. Since this downward force acts as a bending moment on the adjusting screw a, the turning operation of the adjusting screw a becomes difficult, and the turning position of the connecting member c cannot be adjusted smoothly. Was occurring.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to FIGS. 1 to 6 show an embodiment of the hinge according to the present invention. The hinge 1 shown in these figures includes a fixing member 2 and a connecting member 5.
And an adjusting screw 7 as main components.

As shown in FIGS. 1 and 6, the fixing member 2 has a mounting plate 3 and a guide plate 4. Mounting plate 3
, Which form a flat, by screws inserted through the screw insertion hole 3a (not shown) is fixed to the opening B ₁ near the inner surface B ₂ of the precursor B of the wardrobe or the like. On the other hand, the guide plate 4 has a substantially U-shaped cross section, and the opening B _{1 of the} frame B is formed.
A top plate portion 4a extending along the inner surface B ₂ to the back side from the side,
Side plate portion 4b projecting from both sides of the top plate portion 4a to the inner surface B ₂ side, and a 4c. And the guide plate 4
Located its base end portion to the opening B ₁ side of the skeleton B, its distal end is arranged to be located on the rear side of the skeleton B, top plate 4
a and is fixed to the mounting plate 3 by bolts 6 screwed to the mounting plate 3. In this case, the guide plate 4 has its protrusion 4d fitted into the concave portion 3b of the mounting plate 3, and
The engaging groove 4e is at the tip of the mounting plate 3 (the end on the back side of the frame B).
It is positioned by being fitted into.

The connecting member 5 has a U-shaped cross section similarly to the guide plate 3, and has a top plate portion 5a and a side plate portion 5a.
b, 5c. A pivotal connection mechanism (not shown) is provided between the distal ends of the side plates 5b and 5c, and a door (not shown) is pivotally coupled via the pivotal connection mechanism. Have been. Therefore, when the connecting member 5 is attached to the fixing member 2, the door is rotatably supported by the frame B. Note that the rotation connection mechanism is configured in the same manner as a known mechanism, and is not directly related to the present invention.

Next, the structure for fixing the connecting member 5 to the fixing member 2 will be described. The connecting member 5 is inserted into the guide plate 4 in a direction perpendicular to the side plates 5b and 5c (the vertical direction of the frame B). ) Is restricted.

An adjusting screw 7 is screwed into the base end of the top plate 4a of the guide plate 4. This adjusting screw 7
Neck 7a and upper and lower holding portions 7 connected to upper and lower ends thereof
b, 7c. These outer diameters correspond to the lower holding portion 7.
c is the largest, and decreases in the order of the upper holding portion 7b and the neck member 7a. On the other hand, a large hole 5d penetrating the top plate 5a of the connecting member 5 is formed in the center of the top plate 5a.
A small hole 5e extending from the large hole 5d to the base end of the top plate 5a.
Are formed. The large hole 5d is formed such that the upper large diameter portion 7b can be inserted, but the lower large diameter portion 7c cannot be inserted. On the other hand, the width of the small hole 5e is substantially the same as that of the neck 7a, and the neck 7c is insertable, but the large diameter portions 7b and 7c are not insertable. Therefore, when the large hole 5d of the connecting member 5 is opposed to the upper holding member 7b of the adjusting screw 7 and the connecting member 5 is moved in the direction of the arrow in FIG. 2, the upper holding portion 7b of the adjusting screw 7 closes the large hole 5d. The neck 7a enters the large hole 5d. And
The connecting member 5 abuts on the lower large diameter portion 7c. When the connecting member 5 is moved in the direction of the arrow in FIG. 3 in this state, the neck 7a enters the small hole 5e. Here, the length of the neck 7a is substantially the same as the thickness of the top plate 5a of the connecting member 5. Therefore, in a state where the neck portion 7a enters the small hole 5e, the top plate portion 5a of the connecting member 5 is connected to the upper and lower holding portions 7b, 7b.
c. Thereby, the connecting member 5
Movement in a direction orthogonal to the top panel 5a (the left-right direction of the frame B) is restricted.

Further, the movement of the connecting member 5 in the longitudinal direction (the front-back direction of the frame B) is restricted by the engaging mechanism 8. That is, the top plate portion 4a of the guide plate 4 is formed with a long hole 4f extending from the center portion toward the front end and a rectangular hole 4g communicating with the front end of the long hole 4f. The width of the rectangular hole 4g (the width in the direction orthogonal to the side plates 4b and 4c) is smaller than the width of the long hole 4f.

A contact member 9 is fixed to the top plate portion 5a of the connecting member 5 by a bolt 10 at a position facing the long hole 4f. The contact member 9 includes a base 9a fixed to the top plate 5a by bolts 10, a connecting portion 9b extending from the center of the front end of the base 9a to the guide plate 4 side, and a connecting member 9b from the connecting portion 9b. Engagement piece 9c extending to the tip side
It is composed of Width of base 9a (side plates 5b, 5c
Is greater than the width of the elongated hole 4f. The width of the connecting portion 9b is smaller than the width of the rectangular hole 4g as well as narrower than the elongated hole 4f. The width of the engagement piece 9c is smaller than the elongated hole 4f but wider than the rectangular hole 4g. The length of the connecting portion 9b (the length in the direction from the base 9a toward the guide plate 4) is substantially the same as the thickness of the top plate 4a.

As is clear from the above dimensional relationship, the engaging piece 9c of the contact member 9 can be inserted into the elongated hole 4f.
When the base 9a is inserted into the long hole 4f until the base 9a hits the top plate 4a, it passes through the long hole 4f. In this state, the connecting member 5
3 is moved in the direction of the arrow in FIG. 3, the connecting portion 9b enters the rectangular hole 4g, and the engaging piece 9c enters the lower side of the top plate portion 4a to contact the lower surface thereof. When the engagement piece 9c comes into contact with the lower surface of the top plate 4a, the movement of the engagement member 9 in the direction opposite to the direction of the arrow in FIG. 2 is prevented, and thus the movement of the connecting member 5 in the same direction. Will be blocked.

When the adjusting screw 7 is opposed to the large hole 5d, the abutting member 9 has the engagement piece 9c formed in the elongated hole 4f.
Are arranged so as to be able to be inserted. Moreover, when the connecting portion 9b abuts on the side surface on the tip side of the rectangular hole 4g, the neck 7a of the adjusting screw 7 enters the small hole 5e. The position of the contact member 9 can be adjusted in the longitudinal direction of the long hole 4f by loosening the bolt 10.

Side plate portions 4b, 4c on the distal end side of the guide plate 4
A support shaft 11 is provided between them. One end of a lever 12 is rotatably supported by the support shaft 11.
The lever 12 is rotationally urged by a spring 13 so that an intermediate portion thereof abuts against a lower surface of the top plate portion 4a.
At the other end of the lever 12, an operation portion 12a for operating the lever 12 to rotate against the urging force of the spring 13 is formed.

The lever 12 is arranged such that when the connecting member 5 is moved from the state shown in FIG. 2 in the direction of the arrow in FIG. 3, the distal end of the engaging piece 9c abuts on the intermediate part of the lever 12. In this state, when the connecting member 5 is further moved toward the distal end, the connecting member 5 is rotated against the urging force of the spring 13. When the connecting member 5 moves to just before the connecting portion 9b hits the side surface on the tip side of the rectangular hole 4g, FIG.
As shown in (A), the engagement piece 9c gets over the middle part of the lever 12. Then, the lever 12 is returned and rotated by the urging force of the spring 13, and the connecting portion 9b of the contact member 9 is connected.
The intersecting portion 9b is pressed against the side surface on the tip side of the rectangular hole 4g by pressing the intersection of the connecting piece 9c and the engaging piece 9c. As a result, the contact member 9 is sandwiched between the lever 12 and the side surface on the distal end side of the rectangular hole 4g, and the movement of the connecting member 5 in the front-rear direction is restricted.

In the above configuration, when connecting the connecting member 5 to the fixing member 2, the adjusting screw 7 is screwed into the guide plate 4, and the lower holding portion 7 c is abutted against the guide plate 4. Then, the large hole 5d of the connecting member 5 is opposed to the adjusting screw 7, and the contact member 9 is opposed to the long hole 4f.
The connecting member 5 is moved in the direction of the arrow in FIG. 2 until the top plate portion 5a of the guide plate 4 abuts on the lower holding portion 7c and the contact member 9 abuts on the top plate portion 4a of the guide plate 4. Then, the neck 7a of the adjusting screw 7 enters the large hole 5d, and the engaging piece 9c of the contact member 9 passes through the long hole 4f (the state of FIG. 2). Next, the connecting member 5 is moved in the direction of the arrow in FIG. Then, the neck 7a of the adjusting screw 7 enters the small hole 5e, and the engagement piece 9c of the contact member 9 is
(State shown in FIG. 3).

When the connecting member 5 is further moved in the direction of the arrow after the engagement piece 9c abuts on the lever 12, the engagement piece 9c rotates the lever 12 against the urging force of the spring 13. The connecting member 5 is further moved, and the engaging piece 9c is tilted.
Is over the lever 12, the lever 12 is rotated by the urging force of the spring 13, and the engagement piece 9c of the contact member 9 is rotated.
Abuts the end on the proximal side. Then, the engaging piece 9c is pushed toward the distal end, and the connecting portion 9b is pressed against the side surface on the distal end of the rectangular hole 4g. As a result, the connecting member 5 is
Attached to. In this mounting state, the connecting member 5 is prevented from moving in the vertical direction of the skeleton B by the guide plate portion 4 entering the inside thereof, and is prevented from moving in the left and right direction by the adjusting screw 7. And
The engagement mechanism 8 prevents the frame B from moving in the front-rear direction.

When the connecting member 5 is to be removed from the fixing member 2, the operating portion 12a of the lever 12 is pushed down, and the lever 12 is separated from the contact member 9. Thereafter, the connecting member 5 is moved to the base end side. Then, when the adjusting screw 7 enters the large hole 5d and the engagement piece 9c faces the long hole 4f, the connecting member 5 may be moved in the direction opposite to the direction of the arrow in FIG.

The connecting member 5 attached to the fixing member 2 as described above abuts such that the base end of the top plate 5a approaches and separates from the top plate 4a of the guide plate 4. The connecting member 9 is rotatable around a contact point between the connecting portion 9b of the member 9 and the side surface on the distal end side of the rectangular hole 4g, and the turning position of the connecting member 5 can be adjusted by appropriately turning the adjusting screw 7. Can be. In this case, as shown in FIG. 5, upper and lower holding portions 7b,
Each of the opposing surfaces 7d and 7e of the connecting member 5 of the neck 7c is
It is formed on a tapered surface that tapers toward the side. The taper angle of each of the opposing surfaces 7d, 7e is such that even if the connecting member 5 is rotated to the maximum, the connecting members 5
Is set to an angle that is large enough to prevent contact.

As described above, the opposing surfaces 7 of the holding portions 7b and 7c
When d and 7e are tapered surfaces, when the connecting member 5 is rotated by the adjusting screw 7, the connecting member 5
There is no contact with the outer peripheral edge of 7e, and no bending moment acts on the adjusting screw 7. Therefore, the turning operation of the adjusting screw 7 can be easily performed, whereby the turning position of the connecting member 5 can be smoothly adjusted.

Next, another embodiment of the present invention will be described. 8 to 11 show a second embodiment of the present invention. In the hinge 1 'of this embodiment, a fixing bolt 13 is used instead of the engaging mechanism 8. That is, the fixing bolt 13 is screwed to the tip of the top plate 4 a of the guide plate 4. On the other hand, the connecting member 5
An engagement hole 5f having an open distal end is formed at the distal end of the top plate 5a. Then, the connecting member 5 is connected to the guide plate 4.
The connecting member 5 is attached to the fixing member 1 by moving the fixing bolt 13 into the engaging hole 5f from the opening side of the distal end while tightening the fixing bolt 13.

In the hinge 1 'of this embodiment, since the distal end of the connecting member 5 is fixed by the fixing bolt 13, when the adjusting screw 7 is rotated and moved upward in FIG. Adjusting screw 7 and fixing bolt 1 out of 5
3 is elastically deformed so that the connecting member 5
Will be displaced about the distal end. At this time, the adjusting screw 7 is connected to the elastically deformed connecting member 5.
However, the pressing force acts only in substantially the same direction as the arrow in FIG. 8, and does not act as a bending moment. Therefore, although the turning operation of the adjusting screw 7 is more difficult to perform than in the above-described embodiment by the amount pressed by the connecting member 5, no bending moment acts, so that the adjusting screw 7 can be easily turned. In addition, the turning position of the connecting member can be smoothly adjusted.
