Description

[Detailed Description of the Invention] (1) Technical Field of the Invention The present invention relates to a pivot hinge used for doors of buildings, etc., and in particular, the invention relates to a pivot hinge for one mounting member of the pivot hinge and the other mounting member relative to the spindle. This invention relates to a structure in which the mounting position of a door can be adjusted by moving the door relatively.

(2) Prior art and its problems Many conventional flat hinges are available that allow adjustment of the mounting position of the door. Japanese Patent Application Laid-Open No. 55-122980 is used to adjust the door left and right relative to pillars, etc.
There is a hinge according to the publication. This hinge is made by drilling a rectangular hole in a pillar, etc., fixing the casing in the hole, then inserting one wing plate and a spacer plate into the casing, and adjusting the left and right according to the thickness of the spacer plate. It is something to do. Also, in 1987
As shown in No.-139771 and No. 57-80569, instead of the above-mentioned casing, a spacer plate is fixed in the drilled hole, and the left and right adjustment is made between this spacer plate and one of the blade plates via an adjustment screw. There is something to do. In both cases, not only were there a large number of parts, but the installation work was extremely troublesome. In order to eliminate the above drawbacks, the applicant filed Utility Application No. 57-92977
We provide hinges related to No. This is a device in which a round hole is drilled in a pillar or the like, and left and right adjustments can be made using a cylindrical embedded member screwed into the hole and an adjustment screw of the blade plate.

However, with the above hinges, the mounting position of the door can be adjusted from side to side by adjusting the mounting part such as a pillar, and adjusting the mounting part is troublesome. In addition, the above-mentioned hinge has a mounting portion and a shaft portion that are substantially planar, and has a different structure from a so-called pivot hinge, so it cannot be immediately applied. Here, in a pivot hinge, one mounting member is formed by horizontally bending the supporting plate part with a support shaft erected from a substantially vertical mounting plate part, and the other mounting member is attached to the top and bottom edges of the door instead of the edge of the door. They are each fixedly installed, and are attached by assembling both attachment members, and there has been no provision for adjusting the attachment position.

Further, Japanese Utility Model Publication No. 32-4183 discloses an upper bearing adjustment device for a door using a screw shaft, but it has the following drawbacks. Primarily,
Since the screw shafts are provided below the support shaft so as to intersect with each other, the screw shafts are vertically thickened by the amount of intersection, and structurally speaking, the screw shafts cannot be immediately applied to the receiving plate portion of the pivot hinge. In particular, it could not be used as a lower hinge element because the support shaft abuts against the intersecting screw shaft due to the door load. Second, it requires digging on the upper end surface of the door and notching the side surface of the door, making installation cumbersome and limiting the types of doors that can be installed. Thirdly, because the bearing plate is fitted loosely with a gap left in the mounting hole of the receiving plate, dirt and dust may enter the gap, making it impossible to adjust the inclination at a later date. Ta.

(3) Purpose of the invention The present invention was developed in view of the above-mentioned circumstances, and allows the mounting position of the door to be easily adjusted without moving the mounting part of the pivot hinge to the door or pillar. Its purpose is to do so.

(4) Structure of the invention The structure of the invention consists of a receiving plate that extends approximately perpendicularly to the front end of the mounting plate, and a bottomed hole in the receiving plate so that the front and rear walls are parallel to each other. a mounting hole, a relief groove formed in steps around the upper end of the mounting hole, and a bearing plate that is loosely fitted to the front and rear walls with gaps on the left and right sides of the mounting hole, and whose upper center portion serves as a support for the support shaft. a flange that projects horizontally around the upper surface of the bearing plate, and a screw that is screwed in the left-right direction of the rear part of the bearing plate or the receiving plate and has a through hole in the receiving plate as a bearing. It is characterized by comprising a shaft. Hereinafter, the present invention will be specifically explained based on an illustrative embodiment.

The upper surfaces of the mounting plate part 20 and the receiving plate part 21 are flush with each other. A mounting hole 23 with a bottom is formed on the upper surface of the receiving plate portion 21.
Front and rear wall surfaces 23a and 23b are parallel to each other in the left and right directions. The bearing plate portion 4 is loosely fitted into the mounting hole 23 with gaps 5, 5 left and right (see FIG. 3). Front and rear wall surfaces 40a and 40b of the bearing plate portion 4 are parallel to each other, and the front and rear wall surfaces 2 of the mounting hole 23 are parallel to each other.
It is in sliding contact with 3a and 23b. A collar 41 is horizontally projected around the upper surface of the bearing plate portion 4, and this collar 41 is connected to a relief groove 24 formed in steps around the upper end of the mounting hole 23.
smaller than A bearing hole 42 is penetrated through the center of the upper surface of the bearing plate portion 4 toward the lower surface. A female screw hole 43 is passed through the rear portion of the bearing plate portion 4 in the left-right direction. Further, small-diameter through holes 25, 25 are bored in the left and right side walls of the receiving plate portion 21, which are located opposite to the left and right sides of the female screw hole 43, respectively. Each through hole 25, 2
Large diameter storage holes 26, 26 are coaxially connected to the outside of the receiving plate part 5.
The outer surfaces of the left and right side walls are open respectively.
A screw shaft 6 is mounted in the female screw hole 43 and the through holes 25, 25. The screw shaft 6 includes a male threaded portion 60, a large diameter head 61 at the base end of the male threaded portion 60, and a reduced diameter portion 62 at the tip of the male threaded portion 60. The male threaded portion 60 is screwed into the female threaded hole 43, and the head 61 is stored in the left storage hole 26. Reduced diameter part 6

A ring 7 rotatably housed in the right housing hole 26 is fixed to the reduced diameter portion 62 that protrudes into the right housing hole 26 (see FIG. 3). Therefore, the screw shaft 6 is attached by the head 61 and the ring 7 so as to be prevented from coming off. Moreover, the head 61
By inserting a tool such as a screwdriver (not shown) into the cut groove 63 and rotating the screw shaft 6, the screw shaft 6 is rotated using the through grooves 25, 25 as bearings.

The one mounting member 1 and the other mounting member 2 are assembled as follows. The support plate part 11 is disposed on the receiving plate part 21, and a ring-shaped spacer 8 is interposed between the receiving plate part 21 and the support plate part 11. A through hole 80 bored in the center of the spacer 8 , a bearing hole 42 in the bearing plate part 4 , and a bearing hole 13 in the support plate part 11 .
After vertically meeting the support shaft 3, the support shaft 3 is fitted into the bearing hole 42 of the bearing plate 4 from the bearing hole 13 of the support plate 11. The lower end surface of the support shaft 3 is supported by the bottom surface of the mounting hole 23, and the upper end of the support shaft 3 projects somewhat from the upper surface of the support plate portion 11. By grasping and lifting the protruding portion of the support shaft 3, the support shaft 3 can be extracted from the respective bearing holes 13, 42 and the through hole 80.

Next, the structure of the lower pivot hinge B will be specifically explained. As shown in the lower half of FIG. 2, the lower pivot hinge B is paired with the upper pivot hinge A, so the same parts are given the same reference numerals and redundant explanation will be omitted.

A support shaft 3 is erected on the support plate portion 11 of one of the attachment members 1 of the lower pivot hinge B in a fixed state toward the attachment plate portion 10 side. The axes of this support shaft 3 and the upper support shaft 3 are arranged on substantially the same imaginary line. Also,
A mounting hole 23 with a bottom is bored in the receiving plate portion 21 of the other mounting member 2 from the lower surface. This mounting hole 23
The bearing plate portion 4 is loosely fitted therein, and the bearing hole 42 is open to the lower surface side of the receiving plate portion 21 . The one mounting member 1 and the other mounting member 2 are assembled as follows. The spacer 8 is interposed between the support plate part 11 and the receiving plate part 21, and the bearing hole 42 is fitted into the support shaft 3 from above the support plate part 3, and the receiving plate part 21 is placed on the support plate part 11. Allocate. In this assembled state, the ring-shaped lower end surface of the spacer 8 is in contact with the surface of the support plate section 11 around the support shaft 3, and the ring-shaped upper end surface of the spacer 8 is in contact with the surface of the support plate section 4 around the bearing hole 42. touched by the surface.

Pivot hinges A and B configured as above
When assembling the door C to a pillar D etc. in
0, 10 to pillars D located at the top and bottom of door C through countersunk holes 12, 12, respectively, and mounting screws E, E...
Fix it at... At this time, one of the lower mounting members 1 is mounted with the support shaft 3 facing upward. The other mounting members 2, 2 are mounting plate parts 20, 20
countersunk holes 22 and 22 at the right end of the upper and lower end faces of door C, respectively.
Fix it with the mounting screws F, F... from .... After that, attach the spacer 8 to the lower support shaft 3, lift the door C, and insert the lower bearing hole 42 into the lower support shaft 3.
Fit it in. Then, a spacer 8 is interposed between the upper bearing plate part 21 and the support plate part 11, and the bearing hole 1
3, 42 and the through hole 80 are kept in contact with each other, the support shaft 3 is inserted. Thereby, the door C is attached to the pillar D etc. so as to be openable and closable.

By the way, according to the embodiment, the mounting position of the door C can be easily adjusted after the door C is assembled. That is, by rotating the screw shaft 6, the other mounting member 2 is moved in the axial direction of the screw shaft 6 (same as the direction of arrow X) with respect to the support shaft 3 via the bearing plate portion 4. . Therefore, even if the fixing position of the other mounting member 2 with respect to the door C is slightly shifted in the left-right direction, the gap G between the outer frame surface of the door C and the side wall surface of the column D is always suitably adjusted. Moreover, since the mounting position of the door C can be adjusted separately for the upper and lower parts of the door C, the door C can be adjusted in inclination with respect to the pillar D, etc., and assembled in a position that is good in terms of function and appearance.

Further, according to the embodiment, the door C can be assembled more easily than a conventional pivot hinge.
In other words, in conventional pivot hinges, the support shafts were arranged opposite to each other between the support plate parts and the support shafts were attached to the support plate parts, so the other mounting member was fixed to the upper and lower end surfaces of the door, and the connection between the door and the pillar was fixed. After temporarily holding the mounting position by inserting a piece of wood or the like between them, one of the mounting members had to be fixed to a pillar or the like, or one of the supporting shafts had to be made freely retractable. However, in this embodiment, since the upper support shaft 3 is detachably attached to the support plate part 11 and the receiving plate part 21, it can be assembled like a flag hinge.

Further, according to the embodiment, since the cut groove 63 of the screw shaft 6 is arranged on the free end side of the door C, the door C
Even if the screw shaft 8 is in an assembled state such that it is recessed inside the front surface of the column D, etc., the rotation operation of the screw shaft 8 is
There will be no interference from other things.

(6) Modification of the invention FIG. 4 is a sectional view corresponding to FIG. 3 showing a modification of the invention, and parts equivalent to those in the embodiment described above are given the same reference numerals and redundant explanations will be omitted.

The feature of this modification is that the male threaded portion 60 of the screw shaft 6
is screwed onto the receiving plate part 21, and a reduced diameter part 64 is formed in the middle part of the screw shaft 6, and the rear part of the bearing plate part 4 is rotatably fitted into this reduced diameter part 64. Therefore, according to this modification, by inserting a tool such as a screwdriver into the cut groove 63 and rotating the screw shaft 6, the reduced diameter portion 64 of the screw shaft 6 is rotated in the axial direction ( In accordance with this forward and backward movement, the other mounting member 2 is moved in the arrow X direction, that is, in the left-right direction, with the support shaft 3 as a reference via the bearing plate portion 4.

In addition, in the above embodiments and modified examples,
Although an example in which the support shaft 3 is detachably attached to the support plate portion 11 is illustrated, the present invention is not limited to this, and the support shaft 3 may be fixed and erected on the support plate portion 11. It can also be applied to things.

(7) Effects of the invention As explained above, the invention has the following effects.

(a) A receiving plate portion extending approximately perpendicularly to the front end of the mounting plate portion, a mounting hole bored into the receiving plate portion in a bottomed shape and having front and rear walls parallel to each other, and the upper end of this mounting hole. a relief groove formed in steps around the periphery; a bearing plate portion that is loosely fitted to the front and rear walls with gaps on the left and right sides of the mounting hole and whose upper surface central portion serves as a support for the support shaft; and an upper surface of the bearing plate portion. By providing a flange that projects horizontally around the periphery, and a threaded shaft that is screwed in the left-right direction of the rear part of the bearing plate part or the receiving plate part and has a through hole in the receiving plate part as a bearing, We were able to put into practical use a pivot hinge with a door mounting position adjustment mechanism installed on the upper and lower receiving plates, which does not require any processing on the door.

(b) A screw shaft is provided at the intersection of the receiving plate that extends orthogonally from the front end of the mounting plate, so it can be adjusted while it is installed.
In particular, it can be adjusted while checking the inclination with the door etc. open.

(c) Since the flange of the bearing plate part fits into the mounting hole and the relief groove to close the gap, dirt and dust will not enter even after long-term use, and adjustments can be made at a later date if necessary. .
