JP6478365B2 - Pivot hinge with built-in adjustment function - Google Patents

Description

  The present invention relates to a pivot hinge having a door installation adjustment function.

  Conventionally, there are many pivot hinges having a door installation adjustment function, and the mainstream configuration has been reported in JP 2006-274570 PR, JP 2007-231521 PR, JP 2008-121342 PR, etc. Yes. The feature is that the adjustment mechanism portion is arranged at the upper and lower ends of the door suspension side, and the three-dimensional installation adjustment in the left, right, front, rear, top and bottom can be performed with the door closed. And as a basic structure of the front-rear and left-right adjustment, the left-right adjustment screw and the front-rear adjustment screw are used, the position of the front-rear adjustment member is adjusted with the front-rear adjustment screw with respect to the base plate, and the state is on the front-rear adjustment member A configuration in which the position of the left / right adjustment member is adjusted with a left / right adjustment screw is the mainstream.

  However, in the above adjustment mechanism, the front and rear adjustment members and the left and right adjustment members are mainly placed on the flat portion taken out from the door base plate or the thickness portion of the door of the frame base plate, and they can be moved and adjusted independently. Therefore, it is assumed that adjustment screws must be arranged for each member, so a relatively large space is inevitably required, and it is assumed that there remains a problem with compactness. Tend to be expensive.

  In addition, in the configuration in which the adjustment screw is installed and adjusted with the adjustment screw described above, the distance corresponding to the pitch with respect to the number of rotations of the screw becomes the movement distance, and the adjustment screw may need to be rotated considerably in order to move the necessary adjustment width. Arise. And as explained above, when pursuing the compactness of the entire pivot hinge, it is necessary to use an adjustment screw with a small screw diameter as much as possible, and then the screw pitch becomes smaller and the number of times of turning the driver for adjustment tends to increase. Become. In addition, since the cross-shaped bit on the head of the adjusting screw becomes small, if you try to move and adjust a heavy door in the front-rear or left-right direction, a considerable load is applied. There is also a risk of crushing the bit.

  Further, the position of the shaft center of the pivot hinge is advantageously as a trajectory for opening and closing when it is arranged at a position as far away as possible from the door surface and closer to the suspension side. Therefore, it is effective to arrange the adjustment mechanism between the shaft center and the door surface as much as possible.Especially when adjusting left and right, the left and right adjustment screws are oriented parallel to the door, and the head is positioned very close to the door surface. There are many cases. Then, with a thick driver, etc., the back of the hand hits the door surface, and the driver itself tends to be set so that it can only be pressed against the adjustment screw diagonally, making it difficult to adjust it as an improvement It is done.

  Further, a pivot hinge having a configuration different from the adjustment method using the adjustment screw is reported in Japanese Patent Application Laid-Open No. 2000-204829. The configuration is such that the first swing piece is mounted on the door-side base plate so as to be substantially rotatable in the horizontal direction on the first support shaft, and further the second swing shaft is mounted on the first swing piece with the second support shaft. The moving piece is also mounted so as to be substantially rotatable in the horizontal direction, and is adjusted in one direction, either forward or backward, or left and right by a substantially rotating operation around the first support shaft, and centered on the second support shaft. Thus, the adjustment in the other direction is performed by the substantially rotating operation, and the position after the adjustment is fixedly held by using a fixing means for each.

As the means for fixing and holding, both the first support shaft and the second support shaft are constituted by fixing screws, and the fixing screws are set so as to be substantially rotated with the supporting screws serving as fulcrums. Next, a substantially arc long hole is formed at a position away from the first support shaft of the first swing piece, and the first swing piece and the first rocking piece are passed through the substantially arc long hole of the first swing piece with another fixing screw. Fix the moving piece. Similarly, a substantially arc long hole is formed in the second rocking piece, and the first rocking piece and the second rocking piece are fixed with another fixing screw through the substantially arc long hole of the second rocking piece. . That is, the door-side base plate and the first swing piece are fixed by the two fixing screws, and the first swing piece and the second swing piece are fixed. In addition, an operating part where an operating jig such as a spanner is fitted is formed on both the first swing piece and the second swing piece, and both of the two fixing screws for fixing and holding the first swing piece are loosened. In this state, the operation jig was adjusted in one direction, either front, back, left, or right, after which both fixing screws were tightened, and then the two fixing screws that hold and hold the second swing piece were loosened. In this state, an adjustment operation in the other direction is performed with the operation jig, and then the position of the shaft center is maintained by tightening both fixing screws.

  However, in the adjustment mechanism described above, both the first swing piece and the second swing piece are provided with a substantially arc-shaped elongated hole, and a fixing screw is passed through the approximately arc-shaped elongated hole. On the other hand, since it is configured to rotate substantially, it is necessary to form the periphery of the substantially arc long hole as a constant surface shape, and the size of the first swing piece and the second swing piece inevitably increases. As a result, the first swing piece and the second swing piece move in each direction when they are superimposed on the door-side base plate, so that the range becomes even wider, and the overall size of the pivot hinge is made more compact. Is assumed to be insufficient. In addition, an operation part for fitting the operation jig to perform the adjustment operation is provided on both the first rocking piece and the second rocking piece, and the operation part also moves at the same time for adjustment. In addition to being disadvantageous, it is also considered that there is room for improvement because it is necessary to refit the operation jig during each operation.

  Furthermore, the fixing means for the first swing piece and the second swing piece are each made up of two fixing screws, and the adjustment operation is performed after loosening both of the two fixing screws, and thereafter It is necessary to retighten the two fixing screws, and it is preferable that the number of operations of the fixing screw in the adjusting operation is reduced, which can be further simplified. In the state where the two fixing screws are loosened at the same time during the adjustment, the side of the first swing piece or the second swing piece that is adjusted left and right is the door weight on the upper pivot hinge. In addition, there is a concern that the lower pivot hinge may be subjected to a moment force that tends to move toward the suspension base, and the door may move without permission when the fixing screw is loosened. Therefore, at the stage of adjustment, it is necessary to tighten and tighten the fixing screw while holding the position of the first or second rocking piece with the operation jig. become.

  Therefore, the shape of the first rocking piece and the second rocking piece is equipped with means that can narrow the moving range in the front-rear or left-right adjustment, and is provided on both the first rocking piece and the second rocking piece. The first object is to realize a more compact configuration as a whole by integrating the operation parts in one place. The second object is to improve the operability during adjustment by eliminating the operation of shifting the position due to the weight of the door even when the fixing screw is loosened especially during left-right adjustment, and reducing the number of fixing screws. .

  First, a substantially Z-shaped door-side base plate having a mounting surface having mounting holes, a surface continuously bent at a right angle, and a take-out horizontal surface bent at a right angle is provided. Next, a first oscillating piece having a substantially plate shape and having a long hole at the center, a curved side at one end, and a first support shaft insertion hole on the opposite side is provided. Then, the first swing piece is mounted on the horizontal surface of the door-side base plate so as to be rotatable about the first support shaft, and the first height matching piece having the same thickness as the first swing piece is fixed to the door-side base plate. To do. At this time, it is set so that the curved side of the first swing piece moves close to the side of the first height adjustment piece, and the first swing piece and the first height adjustment piece can be tightened simultaneously. A first female screw portion is provided at the position, and the first fixing screw is screwed together. The first support shaft is formed by a pin-shaped shaft with a collar, and is mounted so as to have a friction force of a predetermined level or more in a compressed state by inserting a disc spring between them.

  Next, a second oscillating piece having a substantially plate shape and having a connecting shaft fixing hole at the center portion, a curved side at one end, and a second support shaft insertion hole and an operating portion on the opposite side is provided. . The second rocking piece is arranged on the surface of the first rocking piece so that the connecting shaft fixing hole overlaps with the long hole of the first rocking piece in a state of being substantially rotatable around the second support shaft insertion hole. Then, the second pivot is mounted so as to be substantially rotatable, and a second height adjusting piece having the same thickness as the second swing piece is fixed to the first swing piece. At this time, it is set so that the curved side of the second swing piece moves close to the side of the second height adjustment piece, and the second swing piece and the second height adjustment piece can be tightened simultaneously. A second female screw portion is provided at the position, and the second fixing screw is screwed together. Also, it is formed of a pin-shaped shaft with a second support shaft and is mounted so that the first rocking piece and the second rocking piece have a friction force greater than a predetermined value with a disc spring inserted and compressed. Keep it.

  Here, the shape of the operation part of the second rocking piece is not particularly limited, but one end of the second rocking piece has a predetermined height in the vertical direction, and is in the shape of a rod or plate such as a driver. A shape that can be fitted with the adjustment jig is good. A bearing member that fits the upper shaft and the lower shaft is disposed on the surface of the take-out horizontal surface of the door side base plate opposite to the first swing piece and the second swing piece. In a state of passing through the door side base plate, the connecting shaft is inserted into the connecting shaft fixing hole of the second swinging piece to fix both. Therefore, a substantially odd-shaped square hole for moving the connecting shaft is provided in the central part of the horizontal surface of the door-side base plate. Then, with the second fixing screw tightened, loosen only the first fixing screw and move and adjust the first swing piece by rotating the operating part with an adjusting jig. In the tightened state, only the second fixing screw is loosened and the operation part is substantially rotated to adjust the movement of the second swinging piece. It becomes possible to adjust to.

  When attaching the first and second fixing screws, insert the toothed washer and the disc spring in the order in which the disc spring is on the flange side of the fixing screw, and the toothed washer has a high orientation of teeth. If it is arranged so that it faces the end face plane of the fitting piece and the curved side, the door-side base plate and the first swing piece can be fixed and held further firmly. It becomes possible. In addition, by mounting a disc spring together with the first support shaft and the second support shaft so that it can rotate freely, even when the first fixing screw and the second fixing screw are loosened, It is possible to maintain the position as it is with respect to the load to be moved, and it is possible to perform the adjustment work more easily.

  In the door-side lower pivot, a connecting shaft for connecting and fixing the second swing piece and the lower bearing member is provided with a through hole and a vertical adjusting female thread in the vertical direction of the central portion, and the through hole is blocked. The second rocking piece and the lower bearing member are fixed so that there is not. Then, the vertical adjustment screw is screwed into the vertical adjustment female thread portion through the through hole from the second swinging piece side. Then, the vertical adjustment of the structure which lifts the door side lower pivot by turning the vertical adjustment screw after the door is suspended can be further added.

  By using a configuration in which the door-side base plate, the first rocking piece, and the second rocking piece are superposed and operated to rotate substantially, one of the first fixing screw and the second fixing screw is loosened. Adjust the installation in the front-rear direction or the left-right direction by simply rotating the operation part with a rod-shaped adjustment jig, placing the door at the appropriate position, and then tightening the loosened fixing screw again. It can be easily implemented.

  The operation part is only one place formed on the second swing piece, and can be installed and adjusted in both the front and rear and left and right directions, and is easy to understand and does not require an operation part on the first swing piece. The overall size can be set more compactly.

  In the fixing means using the first fixing screw and the second fixing screw, the door-side base plate and the first swinging piece to which the height adjusting piece is attached are simultaneously tightened with the first fixing screw, and the height adjusting piece is similarly attached. Since the configuration in which the first swing piece and the second swing piece are simultaneously tightened with the second fixing screw is used, the size of the first swing piece and the second swing piece itself can be reduced. Since the moving range by the moving operation can be reduced, the size of the pivot hinge itself can be made compact.

  A disc spring is interposed between the first support shaft and the second support shaft so that the door-side base plate and the first swing piece, and further, the first swing piece and the second swing piece have a predetermined frictional force. By setting it to rotate approximately, it is possible to prevent the door from moving freely in the direction of moment load due to the weight of the door even when the first fixing screw or the second fixing screw is loosened, especially during left-right adjustment, Furthermore, it is possible to hold the position as it is after adjustment, and it is possible to calm down and slowly tighten the fixing screw, and it is possible to provide a very simple installation adjustment work.

  As the installation adjustment mechanism, the first swing piece, the second swing piece, the first fixing screw, the second fixing screw, and the two height-matching pieces in a state of being stacked on the door side base plate are very few. Consists of the number of parts, can be assembled easily and inexpensively.

  Embodiments of a pivot hinge with a building adjustment function according to the present invention will be described below with reference to the drawings. First, here, the pivots disposed above and below the frame body 40 are referred to as an upper frame side pivot and a lower frame side pivot, and the pivots disposed above and below the door 39 are referred to as an upper door side pivot and a lower door side pivot. FIG. 1 is an assembled perspective view of a lower door side pivot of a pivot hinge with a building adjustment function of the present invention, and FIG. 2 is a top view in the same state. 3 is an assembled perspective view of the upper door side pivot, FIG. 4 is a perspective view of the lower frame side pivot, and FIG. 5 is a perspective view of the upper frame side pivot. FIG. 6 is a side view showing a state in which the door 39 is suspended from the frame body 40 using the pivots described above.

  First, the lower frame side pivot shown in FIG. 4 is directed upward to the horizontal plane 2 of the frame side lower plate 1 and the frame side lower plate 1 bent into an L shape composed of the mounting surface 3 having the mounting holes 4 and the horizontal plane 2. It is comprised from the lower axis | shaft 5 which stood up. Similarly, the upper frame side pivot shown in FIG. 5 similarly has an L-shaped frame side upper plate 6 composed of an attachment surface 3 having an attachment hole 4 and a horizontal plane 2, and a horizontal plane 2 of the frame side upper plate 6. The upper shaft 7 is erected downward. Both are mounted on the top and bottom of the frame body 40. Next, the lower door side pivot shown in FIG. 1 and the upper door side pivot shown in FIG. Then, the lower frame side pivot and the lower door side pivot, and the upper frame side pivot and the upper door side pivot are fitted together to carry out the hanging work, so that the overall configuration shown in FIG. 6 is obtained. It is done. In addition, as shown in FIGS. 1 and 3, in this embodiment, all the installation adjustment mechanisms are arranged on the upper and lower door side pivots. At this time, the front and rear adjustment mechanisms and the left and right adjustment mechanisms are the upper door side pivot and the lower door side. Both the pivots are arranged in the same configuration, and the vertical adjustment mechanism is incorporated only in the lower door side pivot. Therefore, the adjustment mechanism and operation will be described below based on the lower door side pivot shown in FIG.

  FIG. 7 is a top view of the door-side base plate 8 and is composed of a mounting surface 3 having mounting holes 4, a surface bent continuously at a right angle, and a horizontal take-out surface 9 bent continuously at a right angle. It has a substantially Z shape, and has a substantially odd-shaped square hole 10 at the center position of the horizontal take-out surface 9, a first spindle insertion hole 11 at the lateral position, and a first female thread portion 14 at the opposite lateral position. Keep it. Next, FIG. 8 is a top view of the auxiliary plate 12, which has a plate shape and has the same outer shape as the horizontal take-out surface 9 of the door-side base plate 8, and also has a substantially odd-shaped square hole 10 and an arc-shaped groove 13 at the center position. The first female screw portion 14 is provided on the opposite side of the first support shaft insertion hole 11 in the lateral position, and is overlapped and fixed on the horizontal take-out surface 9 of the door-side base plate 8. Further, a plate-like first height adjustment piece 15 is arranged in a state of being further overlapped in the vicinity of the first female screw portion 14, and the three parties are completely integrated as shown in FIG.

  Here, the auxiliary plate 12 shown in FIG. 8 is not essential in terms of the mechanism. However, the strength factor of the door-side base plate 8 itself is increased, and the first swing piece 16 and the second swing piece 17 are further added as shown in FIG. When the first fixing screw 18 and the second fixing screw 19 are fixed after being overlapped with each other, the tip thereof does not come into contact with the take-out horizontal surface 9 of the door-side base plate 8 and can be moved substantially when rotating. Since it is possible to provide a circular arc-shaped groove 13, it is effective to arrange it in a state of being sandwiched between the door-side base plate 8 and the first height adjustment piece 15 in manufacturing by sheet metal pressing. It is. Therefore, the first female screw portion 14 may be disposed on any of the three components. In addition, if not sticking to the sheet metal press product, a cast product having the shape of FIG. 9 may be manufactured as it is.

  FIG. 10 is a top view of the first oscillating piece 16, which has a long hole 20 in the left-right direction at the center position, and a second support shaft insertion hole 21 on the near side across the second hole 20 at the back position. The first support shaft insertion hole 11 is formed laterally with respect to the long hole 20, and the outer peripheral portion on the opposite side is formed as a curved side 23. Next, a second height adjusting piece 24 is arranged in the vicinity of the second female screw portion 22 at the back position and integrated with the first swing piece 16. As shown in FIGS. 1 and 2, the first rocking piece 16 is overlaid on the auxiliary plate 12, and the first support shaft 25 is passed through the first support shaft insertion hole 11 so that both can be rotated. Installing. At this time, the thickness of the curved side 23 portion of the first swing piece 16 and the thickness of the first height matching piece 15 are set to be the same, and the curved side 23 is further aligned with the side surface of the first height matching piece 15 and the first height matching piece 15. It is set so as to be close to the female screw portion 14. Then, the first fixing screw 18 is screwed into the first female screw portion 14 to fix the first height adjusting piece 15 and the first swinging piece 16 simultaneously.

  Moreover, in the said embodiment, it is the structure which implements the installation adjustment of the front-back direction by the substantially rotational motion of the 1st rocking | fluctuation piece 16 with respect to the door side base plate 8, and FIG. 11 is the locus | trajectory diagram which showed the movement operation | movement. . Here, the first fixing screw 18 is loosened with respect to the reference position where the long hole 20 of the first swing piece 16 shown in FIG. Is substantially rotated about the first support shaft 25, and the position of the long hole 20 of the first swing piece 16 is moved and adjusted in the front-rear direction as shown in FIGS. 11 (a) and 11 (c). Is possible. At this time, if the curved side 23 is set so as to rotate substantially in a state as close as possible to the side surface of the male screw portion of the first fixing screw 18, the collar portion of the first fixing screw 18 is effectively used when tightening. be able to. The first rocking piece 16 can be completely fixed and held by tightening the first fixing screw 18 at an arbitrary position after the movement adjustment.

  Next, FIG. 12 is a top view of the second oscillating piece 17, which has a connecting shaft fixing hole 26 at the center, the outer periphery of the back position is formed as a curved side 23, and the second support shaft is inserted on the opposite front side. The hole 21 and the operation part 27 are formed. Although the shape of the operation portion 27 is not particularly limited, it is preferable that the operation portion 27 has a predetermined height and a concave portion so that a rod-like or plate-like adjustment jig 28 such as a driver can be easily fitted, as shown in FIG. It is preferable to form the operation portion 27 of the second swing piece 17 in a shape in which the plate material is bent from both sides and to stand, and the adjusting jig 28 can be inserted between the both standing portions. The thickness of the second swing piece 17 is set to be the same as the thickness of the second height adjusting piece 24. Then, the second support shaft 29 is inserted into the second support shaft insertion hole 21 in a state where the second support shaft 29 is further superimposed on the first swinging piece 16 and mounted so as to be substantially rotatable. At this time, the connecting shaft fixing hole 26 is disposed on the long hole 20 of the first swing piece 16 so that the curved side 23 of the second swing piece 17 is positioned in the vicinity of the second female screw portion 22, and the second The fixing screw 19 is screwed into the second female screw portion 22 to fix the second height adjusting piece 24 of the first swing piece 16 and the curved side 23 portion of the second swing piece 17 simultaneously.

  Then, the bearing member 30 and the second swing piece 17 are shown in a state where the connecting shaft is provided and the horizontal take-out surface 9 of the door-side base plate 8 in the stacked state, the auxiliary plate 12 and the first swing piece 16 are sandwiched. As shown in FIG. 6, the connecting and fixing are different in shape between the upper door side pivot and the lower door side pivot. FIG. 13A is a perspective view of the upper connecting shaft 31, which is substantially cylindrical and has upper and lower ends as a small diameter portion 32 and a middle portion as a large diameter portion 33. Then, in the upper door side pivot, as shown in FIG. 3, the small diameter portions 32 at both ends of the upper connecting shaft 31 are inserted into the connecting shaft fixing holes 26 of the upper bearing member 30 and the second swinging piece 17 and crimped. It is good to make a complete fixed connection using. At this time, the length of the large-diameter portion 33 is set slightly longer than the total thickness of the laminated layers. Further, the middle large-diameter portion 33 is set to a dimension that allows the middle large-diameter portion 33 to be inserted into the long hole 20 of the first swing piece 16 without rattling.

  13B is a perspective view of the lower connecting shaft 34. Similarly, the lower connecting shaft 34 has a substantially cylindrical shape, with the upper and lower portions being a small diameter portion 32 and the middle being a large diameter portion 33 having the same length as the upper connecting shaft 31. However, a through hole is further formed in the vertical direction on the center line, and a female screw part 35 for vertical adjustment is provided at the center position. Then, as with the upper door side pivot, as shown in FIG. 6, the small-diameter portions 32 at both ends are inserted into the connecting shaft fixing holes 26 of the lower bearing member 30 and the second swinging piece 17, and this time, the outer side like an eyelet. Press firmly to fully connect. Then, when the vertical adjustment screw 36 is screwed into the vertical adjustment female screw portion 35 from the second swinging piece 17 side, the vertical adjustment screw 36 presses the distal end surface of the lower shaft 5 of the lower frame side pivot. Adjustments can be made. Further, in the configuration in which the tip of the vertical adjustment screw 36 is directly pressed against the lower shaft 5, there is a concern that the vertical adjustment screw 36 may be rotated by the opening / closing operation of the door 39, and therefore the lower bearing member 30 as shown in FIG. 6. It is better to have a double structure.

  Further, in the embodiment, the substantially pivoting movement of the second rocking piece 17 with respect to the first rocking piece 16 is adjusted in the left-right direction, and the connecting shaft fixing hole 26 of the second rocking piece 17 is the first as shown in FIG. As shown in FIGS. 14 (a) and 14 (c), when the second swing piece 17 is substantially rotated, with reference to FIG. 14 (b) located at the center of the long hole 20 of the single swing piece 16, as shown in FIG. The left / right adjustment function can be obtained. In this operation, the large-diameter portion 33 of the lower connecting shaft 34 actually moves linearly along the long hole 20 of the first oscillating piece 16, so that the second oscillating piece as shown in FIG. 17 second spindle insertion holes 21 may be formed long in the front-rear direction. As described above, if the curved side 23 of the second rocking piece 17 is set so as to rotate substantially in a state as close as possible to the side surface of the male screw portion of the second fixing screw 19, The collar portion of the screw 19 can be used effectively, and the second rocking piece 17 can be completely fixed and held by tightening the second fixing screw 19 at an arbitrary position after movement adjustment.

  Therefore, as a whole adjustment procedure, when the front-rear adjustment is performed first, the second fixing screw 19 is first tightened, and only the first fixing screw 18 is loosened and the adjustment jig 28 is attached as shown in FIG. It is only necessary to substantially rotate the operating portion 27, and the bearing member 30 connected by the upper connecting shaft 31 or the lower connecting shaft 34 is moved and adjusted in the front-rear direction, and the first fixing screw 18 is tightened again at an arbitrary position. This completes the longitudinal adjustment. In FIG. 15, the adjustment jig 28 is illustrated using a screwdriver, but the shape of the adjustment jig 28 is not particularly limited. Then, in the state where the first fixing screw 18 is tightened, only the second fixing screw 19 is loosened and the operation portion 27 is substantially rotated to adjust the movement of the second swing piece 17 in the same manner. The member 30 is moved and adjusted in the left-right direction, and the second fixing screw 19 is tightened again at an arbitrary position to complete the left-right adjustment. As a result, the position of the door 39 relative to the frame body 40 can be installed and adjusted in the front-rear direction or the left-right direction. Further, there is no order in the front-rear direction and the left-right direction in the adjustment operation, and the adjustment operation may be performed from either side. In the lower door side pivot, the vertical adjustment screw 36 can be adjusted in the vertical direction by turning the vertical adjustment screw 36.

  The important point here is that when the first swing piece 16 and the second swing piece 17 are mounted on the second support shaft 29, the door 39 is closed if it is extremely light and can be substantially rotated. When the second fixing screw 19 is loosened in an attempt to make a left / right adjustment from the above state, the moment load due to the weight of the door 39 is applied to the door end side of the upper door side pivot and to the suspension base side of the lower door side pivot. It is conceivable that the door 39 moves without permission when the fixing screw 19 is loosened. Then, in the configuration as it is, an adjustment jig 28 such as a dedicated square bar is prepared separately, and the second fixing screw 19 is loosened with a screwdriver, and at the same time, adjustment work is performed at an appropriate position with the adjustment jig 28, It will be necessary to fix again. However, this operation requires not only a separate adjustment jig 28 but also a work using both hands, which is not sufficient in terms of simplifying the adjustment work.

  Therefore, as shown in FIGS. 1 and 3, when the second support shaft 29 is inserted into the second support shaft insertion hole 21, the disc spring 37 or the spring washer or the resin washer is fitted and then they are strongly compressed. It is good to caulk so that Then, a predetermined or more frictional force is generated between the first swinging piece 16 and the second swinging piece 17, and if this frictional force is set larger than the moment load due to the weight of the door 39, Even when the second fixing screw 19 is loosened, the door 39 maintains the position as it is. Further, when the adjustment jig 28 such as a screwdriver is fitted to the operation portion 27 and the adjustment operation is performed, since the lever force is applied, the adjustment work is not so heavy and can be easily performed. As a result, it is possible to perform the left / right adjustment without having to hit with a single driver, and the operability of the adjustment can be further improved.

  In addition to the normal opening / closing operation of the door 39, it is necessary to assume that a child is hanging on the door tip or that a sudden load is applied to the door surface. Therefore, when the first fixing screw 18 and the second fixing screw 19 are mounted, the toothed washer 38 and the disc spring 37 are inserted in the order in which the disc spring 37 comes to the flange side of the fixing screw, and the toothed washer 38 is inserted. The teeth are arranged so that the direction of the teeth is in the plane direction of the height matching pieces and the curved sides 23. Then, even when the tightening force is slightly weak, the disc spring 37 is compressed, so that the toothed washer 38 has the surface of the second swing piece 17 and the second height-matching piece 24, the first swing piece 16 and the first height. It will bite into the surface of the fitting piece 15 at the same time, and can be held more firmly. Further, since the adjustment mechanism has many irregularities such as screw heads as shown in FIG. 1, the design can be improved by attaching a decorative cover such as resin as shown in FIG.
