Description

  The present invention relates to a hinge for attaching a door to a fixed frame so that the door can be freely opened and closed, and a door unit using the hinge.

  For example, when installing a door such as a door for entering and exiting a room to a door mounting frame such as a fixed frame, the mutual interval (gap) between the door and the door mounting frame is set so that the door can be opened and closed smoothly. It is necessary to adjust within a predetermined range. Further, even when the door or the door mounting frame portion is deformed or the mounting position of the door is shifted due to use, it is necessary to readjust the mutual distance between the door and the door mounting frame portion. And in order to perform these adjustments properly, the thickness direction of the door (the front-rear direction of the operator facing the front of the door), the door width direction (also the left-right direction) and the door height direction (also the up-down direction) The hinge which enabled position adjustment (gap adjustment) of these three directions is disclosed (refer patent document 1).

Japanese Patent No. 3747102

  According to such a hinge, the mutual distance (gap) between the door and the door mounting frame can be adjusted to an appropriate range by adjusting the position of the door in the front-rear, left-right, and vertical directions. However, in the hinge of Patent Document 1, the position adjustment in the front-rear direction of the door can be performed when the door is closed, but the position adjustment in the left-right direction of the door cannot be adjusted when the door is closed. Therefore, it is desired to adjust the position of both of them with the door closed.

  An object of the present invention is to provide an improved hinge and a door unit using the hinge so that the position adjustment in the front-rear direction and the left-right direction can be easily performed with the door closed.

In order to solve the above problems, the hinge of the present invention is
One side of the door in the left-right direction to open and close a door that has the same shape as the fixed frame and has a predetermined thickness in the front-rear direction inside the fixed frame that extends in the left-right direction and the up-down direction. The door side mounting member is fixed to the outer end surface of the frame, and the frame side mounting member is fixed to the opposing inner surface of the fixed frame facing the outer end surface, and the door side mounting member and the frame side mounting member are connected to the frame side. A hinge that is pivotally connected around a pivot axis of a hinge shaft that vertically passes through the mounting member;
When it is arranged in the left and right gap formed between the outer end surface of the door and the opposed inner surface of the fixed frame, and the surface orthogonal to the rotation axis is an adjustment surface, the door side in the adjustment surface An adjustment reference member in which the distance in the left-right direction from the mounting member is maintained constant;
The adjustment reference member is disposed between the adjustment reference member and the door-side mounting member, and the adjustment reference member is adjusted with respect to the adjustment reference direction when the direction from the rotation axis to the left-right clearance is defined as the adjustment direction. A first adjusting member for moving the door-side mounting member in the front-rear direction directly or indirectly through another member by applying a first adjusting force along the direction;
In addition to being arranged between the adjustment reference member and the door-side attachment member, and for moving the door-side attachment member in the left-right direction, the adjustment reference member is provided separately from the first adjustment member. A second adjustment member for applying a second adjustment force along the adjustment direction;
A direction changing mechanism that is disposed between the adjustment reference member and the second adjustment member, and that converts an action direction of the second adjustment force by the second adjustment member into a left-right direction;
With
While the door-side mounting member moves in the front-rear direction by the first adjustment force from the first adjustment member, the position in the front-rear direction with respect to the fixed frame of the door can be finely adjusted.
By the second adjusting force from the second adjusting member, the direction changing mechanism moves the door-side mounting member in the left-right direction, thereby forming the left-right gap, and the outer end surface of the door and the fixed frame It is characterized in that the distance between the opposing inner surfaces can be finely adjusted.

  In the hinge described above, the first adjustment member (for example, the front and rear adjustment screw) is adjusted to cause the first adjustment force to act in the adjustment direction (that is, the direction from the rotation axis toward the left and right gaps), so that the door side mounting member (for example, the door) The fixed plate is moved in the front-rear direction (thickness direction). Further, the second adjustment force is applied in the adjustment direction by the adjustment operation of the second adjustment member (for example, the left and right adjustment screw), and the door side mounting member is moved in the left and right direction (width direction) via the direction changing mechanism. In this way, by adjusting the first adjustment member and the second adjustment member in a common adjustment direction, the door and the fixed frame can be closed with the door closed (for example, from the front side or the rear side of the door). Since an appropriate gap can be found efficiently while actually visually recognizing the mutual gap, position adjustment in the front-rear and left-right directions of the door can be easily performed. When the adjustment direction is the front-rear direction of the door, the direction of action of the first adjustment force and the second adjustment force coincides with the front-rear direction of the door. Can be adjusted more easily.

  In addition, in the adjustment surface (ie, the surface orthogonal to the rotation axis), the door (door-side mounting) is maintained with a constant horizontal distance between the adjustment reference member (for example, the reference plate) and the door-side mounting member. Since the position adjustment of the member) in the front-rear direction and the left-right direction is performed, the position of the door can be adjusted from the position where the left-right gap can be seen using the adjustment reference member as a mark (index). By the way, when position adjustment of the door (door side mounting member) in the front-rear direction and the left-right direction is performed with the distance between the adjustment reference member and the rotation axis maintained in the front-rear direction constant, When the action direction of the second adjusting force by the two adjusting members is converted to the left and right directions via the direction changing mechanism, the door (door side mounting member) is hardly displaced in the front and rear directions. Position adjustment in the left-right direction can be performed very accurately.

The hinge direction changing mechanism is
A moving body that moves in the adjustment direction by a second adjustment force from the second adjustment member;
By inserting and holding the hinge shaft on the base side, the hinge shaft can be rotated relative to the hinge shaft around the rotation axis, and the tip surface side extending in the adjustment direction has an adjustment surface with respect to the adjustment reference member. A rotating body having an abutting portion that abuts on the inside so that the relative angle can be changed,
Including
While the first adjustment member moves the door-side mounting member in the front-rear direction while maintaining the relative angle between the contact portion of the rotating body and the adjustment reference member,
The second adjustment member changes the relative angle between the contact portion of the rotating body and the adjustment reference member and rotates the rotating body around the rotation axis, thereby moving the door-side mounting member left and right via the adjustment reference member. Can be moved in the direction.

  As described above, the direction changing mechanism includes the moving body (for example, a slider) and the rotating body (for example, a rotating plate), and the contact portion of the rotating body contacts the adjustment reference member so that the relative angle can be changed. By changing the relative angle of the abutment part, it absorbs errors that inevitably occur when the direction of the second adjustment force applied by the second adjustment member is changed to the left and right directions, and in a smooth state without twisting. The position of the door (door side mounting member) can be adjusted in the left-right direction.

Specifically, in the moving body and the rotating body, in order to convert the movement of the moving body in the adjustment direction into the movement of the door-side mounting member in the left-right direction, a direction that intersects both the adjustment direction and the front-rear direction. The engaging portions are respectively formed along
With the second adjustment force from the second adjustment member, the moving body and the rotating body are engaged with each other at the engaging portion as the moving body moves in the adjusting direction, and the rotating body is rotated to adjust the reference. The member and the door-side mounting member can be moved in the left-right direction.

  As described above, the second adjustment force, which is the acting force in the adjustment direction, is first converted into the rotational force of the rotation body by the engaging portions formed on the moving body and the rotation body, and further, the adjustment reference member and the door By converting the side mounting member into the moving force in the left-right direction, the position adjustment of the door, which is a heavy object, in the left-right direction can be performed very smoothly. In addition, even if the said engaging part comprises the engaging part of a moving body as an engaging recessed part (for example, engaging groove) and the engaging part of a rotating body as an engaging convex part (for example, engaging protrusion), those You may comprise an engagement recessed part and an engagement convex part reversely.

  When the movable body and the rotating body are engaged with each other by the engaging portion and the rotating body rotates, the contact portion of the rotating body can contact the door-side mounting member and / or the adjustment reference member so that the relative angle can be changed. It is desirable to contact and move both members together in the left-right direction.

  Thereby, for example, when the engaging convex portion (engaging protrusion) on the rotating body is fitted into (or pulled out from) the engaging concave portion (engaging groove) on the moving body side, the contact portion of the rotating body is the door. By pushing the side mounting member (or adjustment reference member) in the left-right direction, the mutual distance between the outer end surface of the door and the opposing inner surface of the fixed frame, which forms the left-right gap, can be easily widened (or narrowed).

  In addition, in order to restrain the adjustment reference member and the door-side mounting member so as to maintain a constant distance in the left-right direction, a restraining member that holds both the members may be disposed at both ends in the left-right direction. .

  In this way, the simple distance between the adjustment reference member and the door-side mounting member is always kept constant regardless of the position adjustment in the front-rear direction and the left-right direction of the door by a simple configuration that only provides the restraining member. can do. Such a restraining member can be constituted by, for example, a connecting pin that holds the adjustment reference member and the door-side mounting member in a penetrating manner at both ends in the left-right direction.

At that time, the restraining member is fixed to the door side mounting member,
Each of the adjustment reference member and the rotating body can be formed with a moving recess for allowing the restraining member fixed to the door-side mounting member to move in the front-rear direction.

  As described above, the movement of the restraining member fixed to the door-side mounting member in the front-rear direction, and thus the door, by simply forming the moving recess in the adjustment reference member and the rotating body (for example, through the long hole). Can be adjusted smoothly in the longitudinal direction.

  Further, when the guide portions for guiding the movement of the door-side mounting member in the front-rear direction are formed on the door-side mounting member and the adjustment reference member in parallel with the forming direction of the moving recess, Movement in the front-rear direction (and position adjustment of the door in the front-rear direction) can be performed more smoothly. In addition, even if the said guide part is comprised as a guide recessed part (for example, guide groove) for the guide part of a door side attachment member, and the guide part of an adjustment reference member is a guide convex part (for example, guide protrusion), those guide recessed parts and guide You may comprise a convex part reversely.

In these hinges,
In the frame side mounting member, a pair of cylindrical holding portions for inserting and holding the hinge shaft in a form spaced apart in the vertical direction are formed coaxially with the rotation axis,
A 1st adjustment member and a 2nd adjustment member can be arrange | positioned in an adjustment direction between a pair of holding | maintenance parts, respectively.

  As described above, since the adjustment operation of the first adjustment member and the second adjustment member can be performed in the same direction (adjustment direction) between the pair of holding portions, the hinge can be very easily adjusted in the front-rear and left-right directions. Can be realized. That is, the adjustment operation of both members can efficiently find an appropriate gap while actually viewing the mutual gap between the door and the fixed frame with the door closed (for example, from the front or rear side of the door). it can.

  The hinge shaft that passes through the holding portion is composed of two members that pass through each of the pair of holding portions, and the distal ends of these hinge shafts that protrude through the holding portions are respectively held by the base of the rotating body. May be. In this case, since the pair of hinge shafts penetrates the pair of holding portions and are held at the base of the rotating body (for example, at two locations above and below), the straightness of the rotating axis can be easily maintained, and the front and rear of the door In addition, the position adjustment in the left-right direction is less likely to be out of order.

  In addition, elastic ring-shaped shaft holding members are fitted on the inner peripheral sides of the pair of holding portions, respectively. When the hinge shaft is inserted into each shaft holding member, the hinge shaft is provided around the hinge shaft. In some cases, an engaging ridge that is elastically deformed and fitted into the recessed groove is formed. In this case, since the engaging protrusion is elastically deformed and fitted into the concave groove of the hinge shaft, it can be attached in a state in which removal due to the axial movement of the hinge shaft is reliably restricted.

  When any one of the pair of holding parts is a specific holding part, a moving hinge shaft that is movable in the vertical direction within the specific holding part instead of the hinge axis that is held by the specific holding part. The upper end side of the moving hinge shaft is in contact with the rotating body, and the inner peripheral side of the specific holding portion is screwed with the screw member as the third adjustment member that is in contact with the lower end side of the moving hinge shaft. A threaded portion is formed, and the movable hinge shaft may move in the vertical direction and the rotary body may move in the vertical direction by the rotation of the male screw member.

  As described above, by providing the moving hinge shaft instead of the hinge shaft, it is possible to provide a position adjusting function in the vertical direction in addition to the position adjusting function in the left-right direction and the front-rear direction of the door.

Then, in order to solve the said subject, the door unit of this invention is
While a hinge with a hinge shaft is attached as an upper hinge on the top of the door,
A hinge having a moving hinge shaft instead of the hinge shaft is attached to the lower part of the door as a lower hinge.

  Thus, in the lower hinge, the position adjustment in the three directions of front and rear, right and left, up and down of the door orthogonal to each other, and in the upper hinge, the position adjustment of the door in the left and right direction and the front and rear direction is independent. And the door unit which can be implemented easily in the state which closed the door is realizable.

Or in order to solve the said subject, the door unit of this invention is the following.
A hinge having a moving hinge shaft instead of the hinge shaft is attached to the upper part of the door as an upper hinge and attached to the lower part of the door as a lower hinge.

  This makes it easy to adjust the position of the doors orthogonal to each other in the front, rear, left and right, and top and bottom directions in both the lower and upper hinges independently and with the door closed. An implementable door unit can be realized.

  In the hinge and door unit of the present invention, the “vertical direction” is not limited to the vertical direction, but includes an oblique vertical direction. Further, the hinge may be attached on either the left or right side corresponding to the door opening direction (position of the rotation axis).

  Hereinafter, embodiments of the invention will be described with reference to the drawings. FIG. 1 is a front view illustrating a door unit provided with a hinge according to the present invention in a closed state, and FIG. 2 is a perspective view showing a main part of an upper hinge in a state where the door unit is opened. As shown in FIG. 1, it extends in the left-right direction X (width direction) and the up-down direction Z (height direction), has a rectangular shape, and is the same as the fixed frame 2 inside the fixed frame 2 that constitutes a room entrance and the like. A door 3 serving as a hinged door having a predetermined thickness in the front-rear direction Y (thickness direction: see FIG. 2) is mounted so as to be capable of rotating and opening.

  Specifically, an upper hinge 1U (hinge) is attached to the upper right side of the door 3, and a lower hinge 1D (hinge) is attached to the lower right side to constitute the door unit 100. The upper hinge 1U has a metal door fixing plate 4 (door side mounting member) fixed to an upper portion of the outer end surface 3a of the door 3 by a fastening member such as a mounting screw (not shown) and faces the outer end surface 3a. An upper hinge frame fixing plate 5U (frame side mounting member) made of metal is fixed to the inner surface 2a of the fixed frame 2 to be fixed by a fastening member such as a mounting screw (not shown). In this upper hinge 1U, the door fixing plate 4 and the upper hinge frame fixing plate 5U can be rotated around the rotation axis CL of the metal hinge shaft 6 that vertically passes through the upper hinge frame fixing plate 5U. (See FIG. 2). Similarly, for the lower hinge 1D, the door fixing plate 4 (door side mounting member) is fixed to the lower portion of the outer end surface 3a, and the lower hinge frame fixing plate 5D (frame side mounting member) is fixed to the opposing inner surface 2a. The door fixing plate 4 and the lower hinge frame fixing plate 5D are connected so as to be rotatable about the rotation axis CL of the hinge shaft 6.

  As will be described later, since these hinges 1U and 1D have different holding structures for the hinge shaft 6, the upper hinge 1U with respect to the door 3 can be adjusted in two directions, the front-rear direction Y and the left-right direction X. In the lower hinge 1D, the position can be adjusted in three directions including the vertical direction Z. That is, by adjusting the position of the door 3 in the left-right direction X, the size (mutual interval) of the left-right gap XS formed between the outer end surface 3a of the door 3 and the opposed inner surface 2a of the fixed frame 2 can be changed. In addition, by adjusting the position of the door 3 in the vertical direction Z, the size (interval) of the upper gap ZS formed between the upper surface of the door 3 and the lower surface of the fixed frame 2 can be changed. Therefore, in the following description, position adjustment in the front-rear direction Y and the left-right direction X in the upper hinge 1U will be mainly described in detail. In this case, the upper hinge may be simply referred to as a hinge 1U, and the upper hinge frame fixing plate may be simply referred to as a frame fixing plate 5U.

  Next, FIG. 3 is a front view of the upper hinge viewed from the right outer end surface side of the door, FIG. 4 is an enlarged perspective view showing the contact portion of the rotating plate, and FIG. FIG. 6 is a sectional view taken along the line AA showing the change of the form based on the adjustment in the horizontal direction of the door, and FIG. 7 is an explanatory view of the cross section along the horizontal direction of the door. It is CC sectional explanatory drawing showing a restraint state. 8 shows a door fixing plate, FIG. 9 shows a reference plate, FIG. 10 shows a rotating plate, and FIG. 11 shows a slider.

  As shown in FIG. 3, in addition to the door fixing plate 4, the frame fixing plate 5U, and the hinge shaft 6, the hinge 1U includes a metal reference plate 40 (see FIG. 6) disposed in the left and right gap XS (see FIG. 6). An adjustment reference member 10 and a front / rear adjustment screw 10 (first adjustment member) disposed between the reference plate 40 and the door fixing plate 4 such that the adjustment direction (the direction in which the adjustment force is applied) coincides with the front-rear direction Y. ) And the left / right adjustment screw 20 (second adjustment member), and a direction changing mechanism 50 disposed between the reference plate 40 and the left / right adjustment screw 20 (see FIG. 6).

  The door fixing plate 4 shown in FIG. 8 has a main body portion 4a bent in a rectangular shape with the vertical direction Z as a longitudinal direction fixed to the outer end surface 3a (see FIG. 1) of the door 3, and one of the main body portions 4a ( On the long side of the front side, a support wall 4b is formed so as to project from the middle part toward the front side (right side). In the support wall 4b, a screw hole 4c for inserting and supporting the front / rear adjusting screw 10 in the upper portion and a notch 4d for inserting and supporting the left / right adjusting screw 20 in the lower portion are respectively in the longitudinal direction (adjustment direction). ) (See FIG. 3). Note that the other long side (rear side) of the main body portion 4a is entirely erected on the near side (right side).

  A reference plate 40 shown in FIG. 9 has a rectangular main body 40a formed in a size slightly smaller than the main body 4a (see FIG. 8) of the facing door fixing plate 4 with the vertical direction Z as a longitudinal direction, and a main body 40a. The main body 40a is surrounded by the support wall 40b formed to project from the middle part of one long side (front side) toward the back side (left side) and the remaining three sides excluding the long side where the support wall 40b is formed. The peripheral wall 40e is formed so as to protrude toward the back side (left side). The support wall 40b is disposed to face the support wall 4b (see FIG. 8) of the door fixing plate 4, and is inserted into and supported by the notch 40c for inserting and supporting the front / rear adjustment screw 10 in the upper part and the left / right adjustment screw 20 in the lower part. The notches 40d are formed so as to penetrate in the front-rear direction (adjustment direction) which is the plate thickness direction (see FIG. 3).

  As shown in FIG. 7, the reference plate 40 has a distance XL in the left-right direction X with respect to the door fixing plate 4 and a front-rear direction with respect to the rotation axis CL in a plane (adjustment surface) orthogonal to the rotation axis CL. The Y separation distance YL is maintained constant. Therefore, the reference plate 40 is a reference for adjusting the position of the door 3 when the door fixing plate 4 moves in the front-rear direction Y (see FIG. 5) and when it moves in the left-right direction X (see FIG. 6). Base point).

  Specifically, in the main body 4a of the door fixing plate 4, a plurality of (for example, two) fixing holes 401 (for example, two in total) are arranged in a plurality of rows (for example, two rows) along the front-rear direction Y. Is provided (see FIG. 8). One end portion (left end portion) of a metal connecting pin 7 (restraining member) is fixed to each fixing hole 401 by, for example, caulking. On the other hand, in the main body portion 40a of the reference plate 40, the same number (two) of reference plate long holes 41 (moving recesses) as the rows of the fixing holes 401 are formed penetratingly along the front-rear direction Y (FIG. 9). reference). And the other end part (right end part) side of the connecting pin 7 whose one end part (left end part) is fixed to the main body part 4a of the door fixing plate 4 is inserted and held in each reference plate long hole 41 two by two. (See FIG. 3).

  Therefore, the connecting pin 7 is allowed to move in the front-rear direction Y in each reference plate slot 41, and both ends in the left-right direction X hold the reference plate 40 and the door fixing plate 4 in a penetrating manner. Thus, the separation distance XL in the left-right direction X between the reference plate 40 and the door fixing plate 4 is restrained to be kept constant. Note that a rotating plate long hole 521 (moving recess) having substantially the same shape as the reference plate long hole 41 is also formed in a main body portion 52a of a rotating plate 52 (rotating body), which will be described later, at substantially the same position (see FIG. As shown in FIG. 10, the connecting pin 7 is also inserted into each rotation plate long hole 521. Further, as will be described later, the distance YL between the reference plate 40 and the rotation axis CL in the front-rear direction Y is maintained constant by the contact between the reference plate 40 and the rotation plate 52.

  Further, as shown in FIG. 9, guide protrusions are formed in the middle portion of the two short sides of the peripheral wall 40 e of the reference plate 40 in a form parallel to the formation direction (front-rear direction Y) of the reference plate long holes 41. Reference numerals 42 (guide convex portions; guide portions) are formed so as to protrude toward the back side (left side). On the other hand, as shown in FIG. 8, two guide grooves 402 (guide recesses; guide portions) are formed through the body portion 4 a of the door fixing plate 4 in the front-rear direction Y so that the guide protrusions 42 can be inserted and moved. Has been. Then, when the guide protrusion 42 moves along the guide groove 402 (see FIGS. 5A to 5B), the connecting pin 7 passes through the reference plate long hole 41 and the rotating plate long hole 521. When moving in the front-rear direction Y, the door fixing plate 4 integrated with the connecting pin 7 is guided so as to move smoothly in the front-rear direction Y (see FIGS. 7A to 7B).

  Returning to FIG. 3, a flange portion 10 b having a diameter larger than that of the male screw portion 10 a and smaller than that of the head portion is formed on the shaft portion of the front / rear adjustment screw 10. Similarly, a flange portion 20b having a diameter larger than that of the male screw portion 20a and smaller than that of the head portion is formed on the shaft portion of the left / right adjustment screw 20 as well. Further, the upper front / rear adjustment screw 10 has a flange portion 10b located between the support wall 4b of the door fixing plate 4 and the support wall 40b of the reference plate 40, which are opposed to each other, and the male screw portion 10a is connected to the support wall 4b. Are screwed (penetrated in the front-rear direction Y) (see FIG. 5). On the other hand, the lower left and right adjustment screw 20 has a flange portion 20b between the support walls 4b and 40b, and the male screw portion 20a is screwed into a screw hole 51a of a slider 51 (moving body) described later (in the longitudinal direction Y). (See FIG. 6).

  As described above, since the male screw portion 10a of the front / rear adjustment screw 10 and the male screw portion 20a of the left / right adjustment screw 20 are arranged in parallel to the front / rear direction Y, the propulsive force P1 of the front / rear adjustment screw 10 (first The adjustment force (see FIG. 5) and the propulsive force P2 (second adjustment force; see FIG. 6) of the left and right adjustment screw 20 both act in the front-rear direction Y, which is the adjustment direction.

  The direction changing mechanism 50 shown in FIG. 6 has a function of converting the acting direction (adjustment direction; front-rear direction Y) of the propulsive force P2 of the left-right adjustment screw 20 into the left-right direction X, and propulsion from the left-right adjustment screw 20 A metal slider 51 (moving body) that moves in the adjustment direction (front-rear direction Y) by the force P2 and the hinge shaft 6 are inserted into and held by a bifurcated base 52c (see FIG. 3) to hold the hinge shaft 6 In contrast, a metal rotation plate 52 (rotation body) capable of relative rotation about the rotation axis CL is included.

  Of the direction changing mechanism 50, the rotating plate 52 shown in FIG. 10 has a distal end side (rear side) extending in a direction (adjustment direction) from the base 52c side (front side) toward the left and right gap XS (see FIG. 1). ) Have contact portions 523 and 524 that contact the reference plate 40 so that the relative angle can be changed. Specifically, on the adjustment surface orthogonal to the rotation axis CL, the main body 52a of the rotation plate 52 has a shape that gradually expands from the base 52c positioned on the front side toward the rear side on the opposite side. doing. Then, both end projecting walls 523 (contacting portions) projecting toward the base 52c side (front side) are formed at both ends in the vertical direction of the front end edge (rear end edge) of the main body 52a. Further, an intermediate protruding wall 524 (contact portion) that protrudes toward the opposite side (rear side) of the base portion 52c is formed in the vertical middle portion of the front end edge (rear end edge) of the main body portion 52a.

  On the other hand, as shown in FIG. 9, the reference plate 40 disposed so as to face the rotation plate 52 is a contacted portion 43 that can contact the contact portions 523 and 524 at the rear edge of the peripheral wall 40 e. , 44 (see FIGS. 5 to 7). Specifically, as shown in an enlarged view in FIG. 4, the rear end portions of the two short sides of the peripheral wall 40e are cut off, and the both-end recessed portions 43 (covered) that can come into contact with the both-end protruding walls 523 are obtained. Each contact portion is formed. In addition, an intermediate concave portion 44 (contacted) that can be in contact with the intermediate protruding wall 524 by partially cutting the intermediate portion of the other side (rear side) of the long side of the peripheral wall 40e toward the front side (right side). Part) is formed.

  Accordingly, as shown in FIGS. 6A to 6B and FIGS. 7B to 7C, when the rotating plate 52 rotates relative to the hinge shaft 6 around the rotation axis CL, the rotation plate 52 rotates. The projecting walls 523 at both ends of the moving plate 52 change the contact position of the reference plate 40 with respect to the recessed portions 43 at both ends, and the intermediate projecting wall 524 changes the position of contact with the intermediate recessed portion 44. As a result, the relative angle of the rotation plate 52 with respect to the reference plate 40 is changed, and the rotation plate 52 moves the reference plate 40 and the door fixing plate 4 (door 3) together in the left-right direction X.

  Further, the slider 51 and the rotation plate 52 constituting the direction changing mechanism 50 are provided with an engaging portion 511 along a direction obliquely intersecting the front-rear direction Y (adjustment direction) on the adjustment surface orthogonal to the rotation axis CL. , 522 are formed.

  Specifically, the slider 51 shown in FIG. 11 has an engagement groove 511 (engagement recess) on both sides in the vertical direction Z across the screw hole 51a along a direction obliquely intersecting the front-rear direction Y (adjustment direction). ; Engaging portions) are respectively formed. On the other hand, the rotating plate 52 shown in FIG. 10 obliquely intersects the front-rear direction Y (adjustment direction) on both sides in the vertical direction Z from the inner peripheral edge of the slider insertion hole 52b formed through the central portion of the main body 52a. Engagement protrusions 522 (engagement convex portions; engagement portions) that fit into the engagement grooves 511 are formed along the direction.

  Therefore, as shown in FIGS. 5A and 5B, when the propulsive force P1 of the front / rear adjustment screw 10 acts on the screw hole 4c of the door fixing plate 4, the rotation plate 52 rotates about the rotation axis CL. do not do. The relative angle of the rotation plate 52 with respect to the reference plate 40 is not changed, and the door fixing plate 4 moves in the front-rear direction Y with respect to the reference plate 40.

  6A and 6B, when the propulsive force P2 of the left / right adjusting screw 20 acts on the screw hole 51a of the slider 51, the slider 51 moves along with the movement of the slider 51 in the front-rear direction Y. The engagement protrusion 522 of the rotation plate 52 is engaged (inserted) into the engagement groove 511, and the rotation plate 52 is rotated about the rotation axis CL. The relative angle of the rotation plate 52 with respect to the reference plate 40 is changed by changing the contact position between the both-end protruding wall 523 and the both-end recessed portion 43 and changing the contact position between the intermediate protruding wall 524 and the intermediate recessed portion 44. The rotation plate 52 moves the reference plate 40 and the door fixing plate 4 (door 3) as a unit in the left-right direction X.

As shown in FIG. 11 (c), the front and rear wall surfaces in which the propulsive force P2 (adjustment force) of the left and right adjustment screw 20 in the front-rear direction Y forms an engagement groove 511 and has an inclination angle α with respect to the front-rear direction Y When acting on 512, a tangential force Pt that is a force sliding along the wall surface 512 and a normal force Pn that is a force pushing the wall surface 512 are expressed by the following equations, respectively.
Pt = P2 · cos α (1)
Pn = P2 · sin α = Pt · tan α (2)

  By the way, the inclination angle α (for example, 30 ° at the maximum) of the expanding curved portion located near the entrance of the left and right ends is larger than the inclination angle α (for example, 25 °) of the parallel flat portion located in the middle of the wall surface 512. The direction is larger. Therefore, since the normal force Pn is relatively large in the expanded curved portion, the engagement protrusion 522 is strongly pushed into the engagement groove 511 at the entrance. On the other hand, since the tangential force Pt becomes relatively large in the parallel flat portion, the engaging protrusion 522 is smoothly fitted (engaged) into the engaging groove 511.

  In addition, the inclination angle β (for example, 20 °) of the engagement protrusion 522 shown in FIG. 10D is generally smaller than the inclination angle α of the wall surface 512 (α> β). Therefore, as shown in FIG. 6A (or (b)), when the engaging protrusion 522 is fitted (or detached) from the engaging groove 511, a large reaction force (law) is applied to the engaging protrusion 522 from the wall surface 512. This corresponds to a linear force Pn), and a rotational moment M around the rotational axis CL is generated in the rotational plate 52 by this reaction force. However, even if such a rotation moment M occurs, the weight of the door 3 is much larger than the weight of the hinge 1U, so that the entire door unit 100 cannot be rotated around the rotation axis CL. Further, the door fixing plate 4 (door 3) cannot move in the front-rear direction Y due to the rotation of the front-rear adjustment screw 10 being stopped. As a result, the rotation of the rotation plate 52 around the rotation axis CL changes the contact position between the both-end protruding wall 523 and the both-end recessed portion 43 and the contact between the intermediate protruding wall 524 and the intermediate recessed portion 44. The position is changed, and the relative angle of the rotation plate 52 with respect to the reference plate 40 is changed, and the reference plate 40 and the door fixing plate 4 (door 3) are moved together in the left-right direction X.

  Next, FIG. 12 shows the upper hinge frame fixing plate 5U. In the frame fixing plate 5U shown in FIG. 12, a pair of holding cylinders 5b and 5c (holding portions) for inserting and holding the hinge shaft 6 in a form extending away from the main body portion 5a in the vertical direction rotate. It is formed coaxially with the movement axis CL. The front / rear adjustment screw 10 and the vertical adjustment screw 20 are arranged in the front / rear direction Y (adjustment direction) between the upper holding cylinder 5b and the lower holding cylinder 5c. Position adjustment in the direction X can be concentrated at one place (see Fig. 3).

  As shown in FIG. 3, a pair of hinge shafts 6 and 6 are used in correspondence with the pair of holding cylinders 5b and 5c of the frame fixing plate 5U. Each hinge shaft 6 protrudes through the corresponding holding cylinder 5b, 5c, and the distal end portion of the hinge shaft 6 passes through a shaft hole 52d formed in a bifurcated base portion 52c of the rotating plate 52, respectively. Therefore, the straightness of the rotation axis CL is maintained.

  Returning to FIG. 12, ring-shaped shaft holding members 5e are fitted and mounted on the inner peripheral surfaces of the shaft holes 5d formed in the pair of holding cylinders 5b and 5c. The shaft holding member 5e is made of a synthetic resin having elasticity (for example, polyacetal, polyamide, etc.) and is formed in a substantially cylindrical shape, so that the entire cylindrical shape is reduced in diameter by elastic deformation and held. It is inserted into the shaft hole 5d of the cylinders 5b and 5c and is fitted therein. Further, on the inner peripheral side of the shaft holding member 5e fitted in this way, when the hinge shaft 6 is inserted through the shaft holding member 5e, the shaft holding member 5e is elastically deformed into a concave groove 6a provided around the hinge shaft 6. Since the engagement protrusion 5f to be fitted is formed, it is possible to prevent the hinge shaft 6 from coming off due to the movement in the direction of the rotation axis CL.

  FIG. 13 shows a frame fixing plate 5D for the lower hinge 1D. In the lower hinge frame fixing plate 5D shown in FIG. 13, in place of the hinge shaft 6 in the upper hinge frame fixing plate 5U (see FIG. 12), in the shaft hole 5d of the lower holding cylinder 5c (specific holding portion). A metal moving hinge shaft 6 ′ which is movable in the vertical direction Z is provided. The upper end side of the moving hinge shaft 6 ′ contacts the base portion 52 c of the rotating plate 52. A female screw portion 5d ′ is formed on the inner peripheral surface of the shaft hole 5d of the lower holding cylinder 5c to be screwed with the male screw member 30 (third adjusting member) that contacts the lower end side of the moving hinge shaft 6 ′. Yes. Therefore, since the moving hinge shaft 6 'moves in the vertical direction Z and the rotary plate 52 moves in the vertical direction Z by the rotation of the male screw member 30, the position adjustment of the door 3 in the vertical direction Z, that is, the upper gap ZS. Adjustment of (refer FIG. 1) can be performed in the form independent of the position adjustment to the above-mentioned front-back direction Y and the left-right direction X mentioned above.

  Next, using FIG. 3 to FIG. 6 and FIG. 13, the position adjustment in the front-rear direction Y and the left-right direction X using the hinges 1U, 1D having the above-described configuration, and the up-down direction using the lower hinge 1D Z position adjustment will be described.

<Position adjustment in the front-rear direction Y> (FIGS. 3 and 5)
In the hinges 1U and 1D, the head of the upper front / rear adjustment screw 10 is rotated in one direction from the front side (left side in FIG. 3) of the left / right gap XS by a work tool such as a driver (not shown). When the propulsive force P1 of the front / rear adjustment screw 10 acts on the screw hole 4c of the door fixing plate 4, the rotation plate 52 does not rotate around the rotation axis CL. Therefore, the relative angle of the rotation plate 52 with respect to the reference plate 40 is not changed, and the door fixing plate 4 moves to the rear side in the front-rear direction Y with respect to the reference plate 40 (FIGS. 5A to 5B). On the other hand, when the head of the front / rear adjustment screw 10 is rotated in the other direction in the hinges 1U, 1D, the door fixing plate 4 moves to the front side in the front / rear direction Y with respect to the reference plate 40 (FIG. 5 (b) ⇒ ( a)).

<Position adjustment in the left-right direction X = Adjustment of the left-right gap XS> (FIGS. 3, 4, and 6)
In the hinges 1U and 1D shown in FIG. 5B, the head of the lower left and right adjustment screw 20 is moved from the front side (left side in FIG. 3) of the left and right gap XS by a work tool such as a driver (not shown). Rotate in one direction. When the propulsive force P2 of the left / right adjusting screw 20 acts on the screw hole 51a of the slider 51, the engagement of the rotating plate 52 with the engaging groove 511 of the slider 51 is accompanied by the rearward movement of the slider 51 in the front-rear direction Y. The mating protrusions 522 are engaged (inserted), and the rotation plate 52 is rotated counterclockwise around the rotation axis CL. By changing the contact position between the both-end protruding wall 523 and the both-end recessed portion 43 and pressing the inner surface 4a of the door fixing plate 4 from the intermediate recessed wall 524 (see FIG. 4) The relative angle of the rotation plate 52 with respect to the plate 40 is changed so that the rotation plate 52 is integrated with the reference plate 40 and the door fixing plate 4 (door 3) to the left in the left-right direction X (the left-right clearance XS is set). Move in the direction of spreading (FIG. 6 (a) ⇒ (b)).

  On the other hand, when the head of the left / right adjustment screw 20 is rotated in the other direction in the hinges 1U and 1D, the rotation plate 52 is moved from the engagement groove 511 of the slider 51 as the slider 51 moves forward in the front-rear direction Y. The engagement protrusion 522 is disengaged (disengaged), and the rotation plate 52 is rotated clockwise around the rotation axis CL. By changing the contact position between the both-end protruding wall 523 and the both-end recessed portion 43, and the intermediate protruding wall 524 is separated from the inner surface of the body portion 4a of the door fixing plate 4 and presses the intermediate recessed portion 44 (see FIG. 4). The relative angle of the rotation plate 52 with respect to the plate 40 is changed so that the rotation plate 52 is integrated with the reference plate 40 and the door fixing plate 4 (door 3). It is moved in the direction of narrowing (FIG. 6 (b) ⇒ (a)).

<Position adjustment in the vertical direction Z = adjustment of the upper gap ZS> (FIG. 13)
In the lower hinge 1D, when the male screw member 30 is rotated in one direction by a work tool such as a driver (not shown), the movable hinge shaft 6 ′ is moved upward in the vertical direction Z, and the rotating plate 52 is moved. It moves upward in the vertical direction Z (in the direction of narrowing the upper gap ZS). On the other hand, in the lower hinge 1D, when the male screw member 30 is rotated in the other direction by a working tool such as a driver, the movable hinge shaft 6 'moves downward in the vertical direction Z, and the rotating plate 52 moves in the vertical direction Z. To the lower side (the direction in which the upper gap ZS is widened).

Thus, the door 3 is closed (for example, from the front side of the door 3) by adjusting the front / rear adjustment screw 10 and the left / right adjustment screw 20 in the front-rear direction Y (adjustment direction). Since the proper gap can be found efficiently while actually visually recognizing the mutual gap between the door 3 and the fixed frame 2, the position of the door 3 in the front-rear direction Y and the left-right direction X can be easily adjusted.
Further, since the direction of action of the propulsive force P1 of the front / rear adjustment screw 10 and the propulsive force P2 of the left / right adjustment screw 20 coincides with the front / rear direction Y of the door 3, the position adjustment of the door 3 in the front / rear direction Y and the left / right direction X is further performed. Easy to do.

  Moreover, in the adjustment plane orthogonal to the rotation axis CL, the front-rear direction of the door 3 (door fixing plate 4) in a state where the separation distance XL in the left-right direction X between the reference plate 40 and the door fixing plate 4 is kept constant. Since the position adjustment in Y and the left-right direction X is performed, the position adjustment of the door 3 can be performed from the position where the reference plate 40 is used as a mark (index) and the left-right gap XS can be seen. Further, the position adjustment of the door 3 (door fixing plate 4) in the front-rear direction Y and the left-right direction X is performed in a state where the distance YL in the front-rear direction Y between the reference plate 40 and the rotation axis CL is also maintained constant. Is called. Accordingly, the position of the door 3 (door fixing plate 4) in the front-rear direction Y when the direction of action of the propulsive force P2 of the left-right adjustment screw 20 (front-rear direction Y) is converted into the left-right direction X via the direction conversion mechanism 50. Since there is almost no deviation, position adjustment in the front-rear direction Y and the left-right direction X can be performed very accurately.

  By the way, the movable hinge shaft 6 ′ shown in FIG. 13 can also be applied to the upper hinge 1 </ b> U (upper hinge frame fixing plate 5 </ b> U). In this case, since the position of the door in the vertical direction Z can be adjusted also on the upper hinge 1U, the convenience of the door unit 100 is further improved.

  In the above embodiment, the hinges 1U and 1D attached to the right opening door (the rotation axis CL is the right side position of the door 3) have been described, but it goes without saying that the present invention can be similarly applied to the left opening door. Yes.
