2. Description of the Related Art An ordinary hinge is composed of two hinge plates pivotally supported on a support shaft so as to be rotatable about the support shaft, and one hinge plate is provided with an opening frame such as an entrance (hereinafter referred to as an opening). Frame)), and the other hinge plate is attached to the door. However, a slight shift in the mounting position of each hinge plate affects the opening and closing of the door. It had been. In addition, when it is necessary to finely adjust the position of the door after installation due to other circumstances, it has been necessary to remove the hinged plate that had been screwed with the conventional hinge, and then reattach it. In order to solve these problems, two hinge plates are separated and one hinge plate with a support shaft is attached to the opening frame, and the other hinge plate is attached to the door and supported separately from the one hinge plate. There has been proposed an adjusting hinge in which a connecting insertion piece pivotally mounted on a shaft is inserted into an insertion hole for receiving the inserting piece provided in the other hinge plate so that both hinge plates are connected to each other to act as a hinge.

FIG. 14 shows an example of an adjustment hinge proposed by the present inventors (JP-A-3-39581). FIG. 1 is an exploded perspective view. The hinge 1 has one hinge plate 6 having support shafts 17 and 18, and another hinge plate 7 having an insertion piece 9 for coupling and an insertion hole 8 for receiving the insertion piece 9. It is roughly formed from. Winding portions 10 and 11 for holding the support shafts 17 and 18 are formed at intervals on the hinge plate 6 so that a C-ring 12 can be mounted between the winding portions 10 and 11. . A winding portion 14 provided at the base end of the insertion piece 9 is fitted into the C ring 12, and the insertion piece 9 is rotatably supported by support shafts 17 and 18.

[0004] The hinge is formed by attaching one hinge plate 6 to the opening frame, attaching the other hinge plate 7 to the door, and inserting the insertion piece 9 into the insertion hole 8 of the other hinge plate 7.
The screws 20 and 22 are inserted into the screw holes 21 and 23 provided in the hinge plate 7, and the insertion piece 9 is fixed to connect the hinge plates 6 and 7.
In the case of this example, the insertion hole 8 is formed slightly larger than the thickness and width of the insertion piece 9, and the leading end is screwed into the screw hole 21 through the hole 24 of the insertion piece 9. The insertion piece 9 is held in the insertion hole 8 by the screw 20, and the position of the insertion piece 9 in the thickness direction is adjusted and fixed by the adjustment screw 23. The position of the door can be moved up and down by adjusting the gap between the inner surface of the frame and the inner surface of the frame and moving the insertion piece 9 up and down by the screws 27 and 28 at the tips of the support shafts 17 and 18. 13 and 26 are wood screw holes for fixing the hinge plate, 15 is a slit portion of the C-ring, and 16 is a notch of the insert 9 when the insert 9 is moved up and down. Alternatively, this is to prevent the lower end from abutting on the winding portions 10 and 11 of the hinge plate 6. Reference numeral 25 denotes a hole into which the tip of the adjustment screw 22 is inserted.

As described above, in the conventional adjusting hinge, since both hinge plates are fixed to the opening frame and the door in advance, and then the insertion piece is inserted and fixed. The operator must hold the door until it is secured. Therefore, it was necessary to work by two people, a person holding the door and a person fixing and fixing the door, or to use a door hanging device or the like. In order to readjust the position of the door, for example, in the left-right direction after it is once fixed, it is necessary to loosen the fixing screw, turn the adjusting screw, adjust the screw, and finally tighten the fixing screw again to fix it again. However, there are inconveniences such as the position of the screw being displaced at the time of screw tightening, the need for readjustment, and the screw coming off the hinge plate due to excessive loosening.

When changing the opening position of the door from the right side to the left side or vice versa, the door is turned upside down, but in the conventional hinge, all the wood screws fixing the hinge plate are removed. Once the hinge body was removed, the inverted door had to be tightened with wood screws again. To deal with these problems, doors and frames with hinges attached to the doors in advance are supplied for left and right use, but there are two types of products, such as manufacturing, packing, storage, and sales. However, even in this case, in the case of changing left and right at the work site, it is necessary to re-tighten with a wood screw. SUMMARY OF THE INVENTION The present invention has been made to solve the above-described various problems in the related art, and it is an object of the present invention to provide a hinge which can easily temporarily fix a door and adjust a position thereof and can cope with a change in a left and right opening / closing position. .

Alternatively, an engaging projection or an engagement recess that can be protruded and retracted is provided on the inner surface of the insertion hole corresponding to the side end, and the insertion piece is held by the projection and the recess. is there.

According to the present invention, in the above, the insertion hole for inserting the insertion piece may be a rectangular hole having an opening in only one direction, but any of the through holes having openings at both ends in the thickness direction of the door may be used. It is preferable to be able to insert the insertion piece from above.

According to a second aspect of the present invention, in order to adjustably fix the insertion piece in the insertion hole, an adjustment screw including three screws A, B, and C is disposed in the insertion hole portion, and the insertion piece is provided in the insertion piece. A, B by inserting the screw shaft into the slit or through hole provided
A and B2 are held by holding the insertion piece with two holding screws.
Adjustment screw C screwed to the hinge plate while holding the screws
Thus, the fixing position of the insertion piece can be adjusted in the thickness direction of the insertion piece.

In this case, the holding screws A and B only need to be able to hold the insertion piece from both sides in the thickness direction, and one may be a bolt and the other may be a nut. The adjusting screw C is a screw portion whose base end is screwed to the hinge plate. The other screw penetrates through the screws A and B to hold both screws, or engages with one of the screws A and B. It may be a combined shape. The screws A, B, and C are combined so that the screws can be screwed, released, or moved forward and backward from one side of the hinge plate.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION In the first aspect of the present invention, if the insertion hole is formed as a through hole in the thickness direction of the door and has openings on the left and right, the other opening is closed with an appropriate lid if necessary. Alternatively, the tip of the insertion piece may reach the other opening, and a lid for the opening is integrally formed with a decorative cover for the side of the hinge plate for covering a screw hole appearing on the side of the hinge plate. May be. The decorative cover is a detachable cover so that the adjusting screw portion easily appears.

The projection and the recess for holding the insertion piece in the insertion hole are usually provided with an engagement recess in the insertion piece and a projection (lock pin) in the insertion hole, but may be reversed. The protruding piece is urged by a spring or the like to protrude, and is concealed when the insertion piece is press-fitted, and when it coincides with the recess, protrudes into the recess and holds the insertion piece so as not to fall off. Usually, the convex piece does not come off once it has been fitted into the concave part, but for example, the convex piece is removed from the concave part by inserting a pin or the like from the other opening of the insertion hole into the groove provided at the side end of the insert piece. You may make it extractable.

The insertion piece does not necessarily need to be long enough to reach the other end of the insertion hole. In the case of the present invention, screws A, B, and C for holding and adjusting the insertion piece can be attached to the insertion hole from one side of the hinge plate, and can be inserted by turning only the adjustment screw from one side of the hinge plate. Since the position of the piece can be adjusted, the position of the adjusting screw does not necessarily have to be at the center in the length direction of the insertion hole. Therefore, the adjusting screw can be provided so as to be located at the tip of the insertion piece, and the mounting position of the adjusting screw can be changed by changing the insertion direction of the insertion piece.
