The lower pivot hinge 4 has a bearing 4a attached to the lower part of the suspension base 2a of the door body 2 and a pivot shaft 4b attached to the lower frame 11 fitted in a pivotable manner.

  Next, details of the upper pivot hinge 3 will be described. Since the upper pivot hinge 3 shown in FIG. 1 is schematically illustrated, the shape, size, and the like are different.

As shown in FIG. 2, the upper frame 10 includes a plate-shaped main body 14 that faces in an out-of-plane direction (inside-outside direction), and an attachment piece 15 that is provided upward toward the outdoor side in the out-of-plane direction of the main body 14. And a rising piece 16 provided upward toward the indoor side in the out-of-plane direction of the main body 14, an eaves provided over the intermediate portion in the vertical direction of the attachment piece 15 and the intermediate portion in the out-of-plane direction of the main body 14. The connecting piece 17, the mounting piece 15, and the main body 14 form a hollow portion 10 a.
A protrusion 15a directed toward the indoor side is provided near the main body 14 of the mounting piece 15. The protrusion 15a and the upper surface 14b of the main body 14 are continuous in the longitudinal direction to form a concave groove 15b directed toward the indoor side.
The connecting piece 17 has a protruding piece 17a toward the outdoor side near the main body 14, and the protruding piece 17a and the upper surface 14b of the main body 14 are continuous in the longitudinal direction to form a concave groove 17b toward the outdoor side.
The concave groove 17b and the concave groove 15b face each other in the out-of-plane direction to form a guide that supports a bearing mounting member, which will be described later, so as to be movable in the longitudinal direction of the upper frame 10.

A cover 18 is attached over the outside of the main body 14 and the upper part of the attachment piece 15.
The upper frame 10 is a heat insulating shape member in which an outdoor side member and an indoor side member having a hollow portion 10a are produced by an aluminum extruded shape member, and the outdoor side member and the indoor side member are connected by a heat insulating material.
As shown in FIGS. 3 and 4, the upper frame 10 is connected with the lower surface 14 a of the main body 14 (the lower surface 10 b of the upper frame 10) in contact with the longitudinal upper ends of the vertical frames 12 and 13.

Then, the attachment piece 15 is in contact with the outdoor side surface 5a of the building housing 5 and fixed with a fixing tool, the main body 14 is inserted into the opening 5b, and the connecting piece 17 and the rising piece 16 are in contact with the upper inner surface of the opening 5b. The main frame 14 is fixed to the building frame 5 with a fixing tool, and the upper frame 10 is attached.
In addition, the shape of the upper frame 10, the connection with the vertical frames 12 and 13, the attachment to the building frame 5, the material, and the like are not limited to those described above, and may be arbitrary.

As shown in FIG. 2, the bearing 3 a of the upper pivot hinge 3 is provided on the upper surface 14 b of the main body 14 (that is, the upper surface 10 c of the upper frame 10) so as to be movable in the in-plane direction within the hollow portion 10 a of the upper frame 10. A bearing mounting member 6 is provided.
As shown in FIG. 2, the pivot shaft 3 b of the upper pivot hinge 3 is attached to the inside of the door body 2 with a bracket 21, and the pivot shaft 3 b projects upward from the upper surface 2 c of the door body 2, and the main body 14 of the upper frame 10. And is rotatably fitted to the bearing 3a.

  Thus, since the bearing 3a and the bearing mounting member 6 are provided on the upper surface 14b of the main body 14 of the upper frame 10, the bearing 3a and the bearing mounting member 6 are not viewed from the lower surface side of the main body 14, and the appearance Good looking.

As shown in FIGS. 2 to 5, the bearing 3 a is provided at a lower portion of the main body 31 and a main body 31 having a shaft hole 30 into which the pivot shaft 3 b is rotatably fitted. It has the overhang | projection part 32 overhanging rather than the outer peripheral surface 31a. For example, it is a cylinder with a hook.
The bearing 3 a is mounted on the upper surface 14 b of the main body 14 of the upper frame 10 so as to be movable in the longitudinal direction of the upper frame 10.

The main body 14 of the upper frame 10 has a first hole 40 through which the pivot shaft 3b is inserted but no bearing 3a, and a second hole 41 through which the bearing 3a is inserted. (That is, in the in-plane direction) spaced apart.
For example, a first hole 40 having the same diameter as that of the pivot shaft 3b (shaft hole 30) and a second hole 41 having a diameter larger than that of the overhanging portion 32 (ridge) of the bearing 3a have centers 40a and 41a in the in-plane direction. A part of the first hole 40 and a part of the second hole 41 are continuous and formed in a substantially daruma shape.
The first hole 40 and the second hole 41 may not be continuous but may be spaced apart in the in-plane direction.

Thus, the bearing 3a can be inserted into the upper surface 14b side of the main body 14 through the second hole 41 from the lower surface side of the main body 14 or pulled out to the lower surface 14a side. It can be attached to or removed from the upper frame 10.
Further, by making the bearing 3a concentric with the first hole 40 (matched position), the bearing 3a (the overhanging portion 32) can be supported so as not to fall on the upper surface 14b of the main body 14, and Since the pivot shaft 3b can be fitted into or removed from the shaft hole 30 of the bearing 3a from the first hole 40, the upper portion of the door body 2 is rotatably supported on the upper frame 10, or the upper frame 10 Can be removed.

The bearing mounting member 6 is mounted so as to be movable in the in-plane direction along the upper surface 14 b of the main body 14 of the upper frame 10. For example, the both ends of the bearing mounting member 6 in the out-of-plane direction are slid and inserted from the longitudinal ends of the upper frame 10 into the grooves 15b and 17b described above, thereby mounting the grooves 15b and 17b (that is, , Guide), and can be moved in the in-plane direction but not in the out-of-plane direction.
The bearing 3a described above is detachably provided on the bearing mounting member 6 from the lower surface side, and the bearing 3a is movable in the in-plane direction together with the bearing mounting member 6.
The bearing mounting member 6 can move in the in-plane direction over the first position where the bearing 3a matches the first hole 40 described above and the second position where the bearing 3a matches the second hole 41. It is like that.

When the bearing mounting member 6 is in the second position, the bearing 3a can be inserted and extracted from the second hole 41, so that the bearing 3a can be mounted on and removed from the upper frame 10.
When the bearing mounting member 6 is in the first position, the bearing 3a is supported by the upper surface 14b of the main body 14 of the upper frame 10 and the bearing mounting member 6 so that the bearing mounting member 6 does not fall over or rattle. 2) (the upper part of the suspension base side 2a) is rotatably supported in the out-of-plane direction.

In this embodiment, the bearing mounting member 6 has a bearing insertion hole 60 opened in the lower surface 6a. The bearing insertion hole 60 is inserted into the main body 31 of the bearing 3a and has an upper hole 61 opened in the upper surface 6b, and an overhanging portion 32 of the bearing 3a is inserted, is continuous with the upper hole 61, and is opened in the lower surface 6a. In the stepped hole having the lower hole 62, the protruding portion 32 is pressed against the upper surface 14b of the main body 14 of the upper frame 10 by the step 63 between the lower hole 62 and the upper hole 61 to support the bearing 3a.
In this way, the bearing 3a (main body 31) protrudes above the upper surface 6b of the bearing mounting member 6, and the pivot shaft 3b can also protrude above the upper surface 6b of the bearing mounting member 6. The bearing mounting member 6 can be made into a thin plate-like compact.

  The bearing insertion hole 60 described above is a hole that is inserted into the overhanging portion 32 of the bearing 3 a and is opened only in the lower surface 6 a, and the bottom surface of the bearing insertion hole 60 is in contact with the upper end surface of the main body portion 31, so You may make it press on the upper surface 14b of the main body 14 of the frame 10. FIG.

As shown in FIG. 3, a pair of screws 19 are screwed together as a stopper nearer to the suspension side (closer to one vertical frame 12) than the bearing mounting member 6 in the main body 14 of the upper frame 10.
That is, the center 40a of the first hole 40 is closer to the door-end side than the center 41a of the second hole 41, and when the bearing mounting member 6 is moved to the second position, the bearing mounting member 6 as shown in FIG. Is positioned in contact with the screw 19 so that the center of the bearing 3a correctly matches the center 41a of the second hole 41.

  As shown in FIGS. 2 and 4, the fixing screw 7 passes through the main body 14 and is screwed to the bearing mounting member 6 from below the main body 14 of the upper frame 10. 1 is used as a fixing means for the bearing mounting member 6.

Thus, in the state where the pivot shaft 3b is extracted from the bearing 3a together with the door body 2 and the door body 2 is detached from the frame body 1, the fixing screw 7 described above is loosened and the bearing mounting member 6 is attached to the upper frame 10. The state is movable in the in-plane direction.
In this state, a tool such as a screwdriver is inserted into the first hole 40 and the second hole 41, and the tool is inserted into the shaft hole 30 of the bearing 3a and moved to an oblique posture, whereby the bearing mounting member 6 is moved to the first position. It moves in the in-plane direction from the position toward the second position, and the bearing mounting member 6 comes into contact with the screw 19 and stops at the second position.
The second position is a position where the bearing insertion hole 60 overlaps the second hole 41.
That is, the bearing mounting member 6 can be moved from the lower surface side of the main body 14 (the lower surface side of the upper frame 10) to the first position and the second position.
The bearing 3 a can be removed from the upper frame 10 by being extracted from the second hole 41.
The bearing mounting member 6 is provided with a knob, and a slit in the in-plane direction is formed in the main body 14. By inserting the knob into the slit, the knob is moved from the lower surface side of the main body 14 in the in-plane direction. You may do it.

When the bearing 3a is attached to the upper frame 10 again or when a new bearing 3a is attached to the upper frame 10, the bearing 3a is inserted into the bearing insertion hole 60 of the bearing attachment member 6 from the second hole 41 as described above. The bearing attachment member 6 is moved toward the first position together with the bearing 3a using a tool.
This first position is a position where the bearing insertion hole 60 overlaps the first hole 40.
Then, the bearing 3 a is attached to the upper frame 10 by screwing the fixing screw 7 to the bearing attachment member 6 again and fixing it at the first position.

  Since it is like this, the bearing 3a can be easily attached to and detached from the upper frame 10.

In the joinery described above, the door tip dust of the door body 2 can be adjusted.
With the lower pivot hinge 4 fixed, by moving the bearing 3a of the upper pivot hinge 3 in the in-plane direction, the upper part of the hanging side 2a of the door body 2 is moved in the in-plane direction together with the pivot shaft 3b. The tip is adjusted.

Next, the structure which moves the bearing 3a for door tip dust adjustment is demonstrated.
As shown in FIGS. 3 and 5, a pair of first screw insertion holes 70 are formed in the main body 14 of the upper frame 10 so as to be separated from each other in the out-of-plane direction, and a pair of second screw insertion holes 71. , 71 are spaced apart in the out-of-plane direction.
The center 70a of the first screw insertion hole 70 and the center 71a of the second screw insertion hole 71 are separated in the in-plane direction, and the center 71a of the second screw insertion hole 71 is hung from the center 70a of the first screw insertion hole 70. The first hole 40 and the second hole 41 described above are positioned closer to the suspension base than the first and second screw insertion holes 70 and 71.
A long hole 72 is formed at a position adjacent to the first hole 40 and the second hole 41 in the main body 14 of the upper frame 10 in the out-of-plane direction. The long hole 72 is a long hole long in the in-plane direction of the upper frame 10.

The bearing mounting member 6 is formed with a pair of first screw holes 64, 64 spaced apart in the out-of-plane direction, and a pair of second screw holes 65, 65 spaced apart in the out-of-plane direction. .
The center 64a of the first screw hole 64 and the center 65a of the second screw hole 65 are spaced apart in the in-plane direction, and the center 65a of the second screw hole 65 is located closer to the suspension base than the center 64a of the first screw hole 64. In addition, the above-described bearing insertion hole 60 is positioned closer to the hanger than the first and second screw holes 64 and 65.

The out-of-plane dimension L1 between the centers 70a of the pair of first screw insertion holes 70 and the out-of-plane dimension L1 between the centers 71a of the pair of second screw insertion holes 71 are the same, and the centers of the pair of first screw holes 64 are the same. The out-of-plane dimension L2 between 64a and the out-of-plane dimension L2 between the centers 65a of the pair of second screw holes 65 are the same.
The out-of-plane dimensions L1 and L2 are the same.

  As shown in FIG. 7, the in-plane dimension L3 of the center 70a of the first screw insertion hole 70 and the center 71a of the second screw insertion hole 71, the center 64a of the first screw hole 64, and the center of the second screw hole 65 are shown. The in-plane dimension L4 of 65a is different. For example, the in-plane direction dimension L4 is 2 mm smaller than the in-plane direction dimension L3.

Thus, as shown in FIGS. 3 and 7, when the center 70a of the first screw insertion hole 70 and the center 64a of the first screw hole 64 coincide with each other, the second screw insertion hole 71 and the second screw hole 65 are provided. However, the center 71a and the center 65a are shifted by 2 mm.
As shown in FIGS. 8 and 9, when the center 71a of the second screw insertion hole 71 and the center 65a of the second screw hole 65 coincide, the first screw insertion hole 70 and the first screw hole 65 communicate with each other. Is shifted by 2 mm.

Therefore, as shown in FIGS. 3 and 7, the fixing screw 7 is moved from the first screw insertion hole 70 to the first screw hole 64, and the fixing screw 7 is moved to the second screw as shown in FIGS. Assuming that the screw insertion hole 71 is screwed into the second screw hole 65, the bearing mounting member 6 moves 2 mm toward the suspending side in the in-plane direction. Can be adjusted.
The amount of movement of the bearing 3a in the in-plane direction is not limited to 2 mm, and the adjustment size of the door tip dust can be appropriately set as an appropriate amount of movement.

Thus, the dimension between the centers of the first screw insertion hole 70 and the second screw insertion hole 71 formed in the upper frame 10 (main body 14), and the first screw hole 64 and the second screw formed in the bearing mounting member 6. The dimension between the centers of the holes 65 is made different so that the fixing screw 7 is screwed into the second screw hole 64 from the first screw insertion hole 70 and the second screw hole 65 is screwed into the second screw hole 65. In some cases, the bearing mounting member 6 is moved in the in-plane direction by the difference in dimension between the centers described above to move the bearing 3a, so that the first and second screw insertion holes 70 and 71 are round holes ( That is, a shape in which the fixing screw 7 is fitted without a gap can be obtained.
Therefore, even if the fixing screw 7 is slightly loosened, the bearing mounting member 6 does not move in the in-plane direction due to vibration or the like, the bearing 3a does not move in the in-plane direction, and the door body 2 does not rattle when opening and closing. The bearing 3a does not come off the upper frame 10.

  As described above, when the fixing screw 7 is extracted from the first or second screw insertion holes 70 and 71, the bearing mounting member 6 freely moves in the in-plane direction, and the first screw insertion hole 70 and the first screw hole 64 and the second screw insertion hole 71 and the second screw hole 65 are not in communication with each other, and the fixing screw 7 may not be inserted. Therefore, as shown in FIGS. 3 and 10, the main body 14 of the upper frame 10 described above is used. The stepped screw 8 is screwed into the screw hole 66 formed in the bearing mounting member 6 from the long hole 72 formed in the shaft, and the end surface 81 of the large-diameter shaft 80 of the stepped screw 8 is in contact with the lower surface 6a of the bearing mounting member 6. The large-diameter shaft 80 and the long hole 72 restrict the amount of movement (distance) in the in-plane direction of the bearing mounting member 6 to the above-described door tip dust adjustment amount (2 mm). That is, it is a means for regulating the in-plane movement amount of the bearing mounting member 6.

  By doing so, since the maximum amount of movement of the bearing mounting member 6 is 2 mm when the fixed screw 7 is extracted, the fixed screw 7 cannot be inserted.

As shown in FIG. 3 and FIG. 6 described above, when the bearing mounting member 6 is moved to the first position and the second position, the amount of movement is larger than the amount of movement at the time of adjusting the door tip dust. Therefore, the fixing screw 7 and the stepped screw 8 are loosened and removed.
Then, as shown in FIG. 6, when the bearing mounting member 6 moves to the second position where it abuts against the stopper (screw 19), the auxiliary screw hole 67 in which the stepped screw 8 is formed in the bearing mounting member 6 from the long hole 72. And the movement of the bearing mounting member 6 toward the door end side is restricted.
That is, the auxiliary screw hole 67 is formed closer to the door end side than the screw hole 66 and separated by the dimension between the centers of the first hole 40 and the second hole 41 described above.

  Since it is like this, the bearing attachment member 6 can be hold | maintained in a 2nd position when removing the bearing 3a from the upper frame 10, or attaching.

As described above, the means for restricting the amount of movement in the in-plane direction of the bearing mounting member 6 to the door tip dust adjustment amount is not limited to screwing the stepped screw 8 from the long hole 72 to the screw hole 66.
For example, by screwing a restricting screw into the main body 14 of the upper frame 10 and inserting the tip of the restricting screw into an in-plane elongated hole formed in the bearing mounting member 6, both ends of the elongated hole in the longitudinal direction are inserted. The amount of movement in the in-plane direction may be regulated to the door tip dust adjustment amount by the portion coming into contact with the tip of the regulating screw.

The above-described fixing means for fixing and releasing the bearing mounting member 6 at the first position has two screw insertion holes and two screw holes, but is not limited thereto, and may be three or more.
Thus, if the number of the screw insertion holes and the number of the screw holes is three or more, the door tip dust adjustment amount of the door body 6 can be increased.
In addition, when the door tip chilli adjustment amount is increased by using three or more screw insertion holes and screw holes, the maximum in-plane direction movement amount of the restricting means is also increased. For example, the length of the long hole 72 in the in-plane direction is increased.

As shown in FIGS. 11 and 12, first, second, and third screw insertion holes 70, 71, 73 are formed in the main body 14 of the upper frame 10, and the first, second, and third are formed in the bearing mounting member 6. Screw holes 64, 65 and 68 are formed.
The dimension L5 in the in-plane direction between the center 65a of the second screw hole 65 and the center 68a of the third screw hole 68 is determined from the dimension L4 between the centers 64a and 65a of the first screw hole 64 and the second screw hole 65. Also make it smaller. For example, it is reduced by 2 mm.

  In this way, when the fixing screw 7 is screwed into the first screw 64 from the first screw insertion hole 70, the fixing screw 7 is fixed when the fixing screw 7 is screwed into the second screw hole 65 from the second screw insertion hole 71. When the screw 7 is screwed into the third screw hole 68 from the third screw insertion hole 73, the position in the in-plane direction of the bearing mounting member 6 can be adjusted in three stages.

As shown in FIGS. 13 and 14, first, second, third, fourth, and fifth screw insertion holes 70, 71, 73, 74, and 75 are formed in the main body 14 of the upper frame 10, and a bearing mounting member is formed. 6, first, second, third, fourth, and fifth screw holes 64, 65, 68, 69, and 69a are formed.
In this case, the adjacent screw insertion holes are partially continuous, and the adjacent screw holes are partially continuous so that the center is shifted.

When the center of any one of the first to fifth screw insertion holes coincides with the center of any one of the first to fifth screw holes, the center of the other screw insertion hole and the center of the other screw hole are shifted. To.
Then, the fixing screw 7 is screwed into the screw hole from the screw insertion hole whose center is matched, and the bearing mounting member 6 is fixed.

  In the fixing means described above, the screw insertion holes and the screw holes are formed at intervals in the in-plane direction. However, the screw insertion holes are elongated in the in-plane direction, and a plurality of screw holes are located at the same position in the in-plane direction. In this case, the fixing screw 7 may be screwed into one screw hole from the long hole.

For example, as shown in FIGS. 15 and 16, a pair of out-of-plane direction long holes 76 are inclined in the in-plane direction in the main body 14 of the upper frame 10, and one end portion in the out-of-plane direction and the other end portion in the out-of-plane direction are in-plane. The screw insertion holes are formed so as to be displaced in the direction.
The width of the long hole 76 is the same as the diameter of the fixed screw 7. When the fixed screw 7 is inserted into the long hole 76, the fixed screw 7 is prevented from moving in the in-plane direction.
A first screw hole 64 and a second screw hole 65 are formed at the same position in the in-plane direction and spaced apart from each other in the out-of-plane direction near the both ends in the out-of-plane direction of the bearing mounting member 6.

As shown in FIG. 15, when the fixing screw 7 is screwed into the first screw hole 64, the fixing screw 7 contacts the out-of-plane direction end 76 a of the long hole 75.
As shown in FIG. 16, when the fixing screw 7 is screwed into the second screw hole 65, the fixing screw 7 contacts the other end 76 b in the out-of-plane direction of the long hole 76.
Since it is like this, it is possible to adjust the door-end chile by moving the bearing mounting member 6 in the in-plane direction by the displacement in the in-plane direction between the one end 76a and the other end 76b in the out-of-plane direction.

  In addition, when the fixing screw 7 is loosened, the fixing screw 7 cannot move in the in-plane direction with respect to the long hole 76. Therefore, the bearing mounting member 6 does not move in the in-plane direction due to vibration or the like. The body 2 does not rattle when opening and closing, and the bearing 3a does not come off the upper frame 10.

As shown in FIG. 17, the long hole 76 is lengthened, and the first, second, and third screw holes 64, 65, and 68 are formed in the out-of-plane range of the long hole 76.
In this way, when the fixing screw 7 is screwed into the first screw hole 64, the screw is screwed into the second screw hole 65, or the screw is screwed into the third screw hole 68, the bearing mounting member 6 is moved to the surface. It is possible to move to three positions in the inward direction.

Since any of the fixing means described above is provided near the door end of the bearing mounting member 6 and the bearing 3a is provided near the suspension base, the fixing screw 7 is rotated by rotating the door body 2 toward the open position. A tool (driver) that tightens and loosens the door 2 does not interfere.
Since it is like this, it is easy to perform door tip chile adjustment operation in the state where door 2 was attached to frame 1.

  As described above, when a plurality of screw insertion holes are formed, a tape or the like can be attached to the lower surface 14a of the main body 14 to close the screw insertion holes.
