Description

  The present invention relates to a hinge device that supports a face member so as to be freely opened and closed, and a fitting including the hinge device.

2. Description of the Related Art Conventionally, as a hinge device that supports a door body that is a face material so as to be freely opened and closed, a hinge device that has a pivot hinge provided at an upper part of the suspension side of the door body and a receiving member provided on an upper frame has been proposed ( For example, see Patent Document 1).
A pivot hinge described in Patent Document 1 includes a case fixed to a door body, a slider provided on the case so as to be movable up and down, a coil spring for urging the slider upward with respect to the case, and a slider. And an operating member for immersing operation downward. Then, by engaging the engagement hole provided on the upper surface of the slider and the pivot shaft portion of the receiving member, the door body is supported by the door frame so as to be opened and closed, and the operation member of the pivot hinge is operated. By immersing the slider inside the case, the engagement between the engagement hole and the pivot shaft portion is released and the door body can be removed from the door frame.

On the other hand, as another hinge device, a pair of pivot members provided on the upper frame and the door are provided, and by engaging a shaft provided on one pivot member and a hole provided on the other pivot member, One that supports the door so as to be opened and closed has been proposed (see, for example, Patent Document 2).
In the hinge device described in Patent Document 2, a contact portion is provided around the shaft of one pivot member, a contact portion is provided in the vicinity of the hole portion of the other pivot member, and these contact portions are in contact with each other. The maximum opening angle of the door can be set.

JP 2006-214165 A JP 2002-242513 A

  By the way, in the conventional hinge device as described in Patent Document 2, although the maximum opening angle of the door can be set, the maximum opening angle that can be set is determined in advance, depending on the installation location of the door, the type of the door, etc. The maximum opening angle cannot be adjusted accordingly. For this reason, in order to adjust the maximum opening angle, it is necessary to replace the contact portion or the pivot member itself, which deteriorates the installation workability and maintainability of the joinery and increases the number of parts. There is an inconvenience.

  An object of the present invention is to provide a hinge device and a joinery that can adjust the opening angle of a face material relatively easily without increasing the number of parts and can improve workability and maintainability.

  A hinge device according to the present invention is a hinge device that supports a face member in a freely openable / closable manner with respect to a support, and includes a hinge body provided on the face material side and a hinge receiver provided on the support side. A rotation mechanism is provided on one of the hinge body and the hinge receiver, and the hinge body and the hinge receiver are non-rotatably engaged with each other on the other side of the rotation mechanism. The mounting angle along the rotation direction of the mechanism is attached to the support so as to be adjustable.

  According to the present invention as described above, a rotation mechanism is provided on either the hinge body or the hinge receiver, and these are non-rotatably engaged with each other, and the attachment angle of the hinge receiver to the support can be adjusted. Since the rotation mechanism and the angle adjustment part of the hinge receiver are arranged in series, even when the opening angle of the face material is restricted by the rotation mechanism, the opening angle can be adjusted at the hinge receiver mounting portion separately from the rotation mechanism. It becomes possible. Therefore, it is possible to finely adjust the opening angle at the hinge receiver without having to modify, adjust or replace the structure and components of the rotating mechanism, making adjustment work relatively easy and improving workability and maintainability. Can be improved.

In this case, in the hinge device according to the present invention, the rotation mechanism includes a rotation support portion provided on the hinge body or the hinge receiver, a rotation member rotatably supported by the rotation support portion, and rotation with respect to the rotation support portion. It is preferable to have a rotation angle restricting means for restricting the rotation of the member to a predetermined angle.
According to such a configuration, since the rotation angle regulating means is provided in the rotation mechanism, the opening angle of the face material can be regulated by the rotation mechanism, so that a contact portion or the like is provided on both the hinge body and the hinge receiver. The structure of the hinge body or hinge receiver on the side where the rotation mechanism is not provided can be simplified. Then, the rotation angle restricting means is configured to restrict the rotation of the rotation member with respect to the rotation support portion in the rotation mechanism, so that the opening of the face material is set at a predetermined angle by the integrally assembled parts (hinge body or hinge receiver). It is possible to regulate, and the accuracy of angle regulation can be improved.

  That is, in the configuration in which the maximum opening angle of the door is regulated by the contact of the contact portions provided on the frame side and the door side pivot members as in the conventional hinge device (Patent Document 2), the door erection adjustment, etc. May cause the contact state of the contact portion to fluctuate and the set maximum opening angle may deviate. On the other hand, in the hinge device of the present invention, since the rotation angle restriction means is provided in the rotation mechanism that is not affected by the adjustment of the built-in, the deviation of the angle restriction setting can be reduced, and as described above. By finely adjusting the opening angle of the face material in the hinge receiver, the accuracy of angle regulation can be improved.

In the hinge device of the present invention, one of the hinge body and the hinge receiver is formed with a protrusion protruding toward the other, and the other is formed with a recess for receiving the protrusion. Are preferably non-rotatably engaged with each other.
According to such a configuration, the projection body and the recess can be engaged with each other so that the hinge body and the hinge receiver can be engaged with each other in a non-rotatable manner with a relatively simple structure. Here, as a configuration in which the protrusion and the recess are engaged with each other in a non-rotatable manner, for example, the protrusion is formed in a prismatic shape, the recess is formed in a square hole shape, or the protrusion and the recess are formed in a spline shape Any appropriate configuration can be used.

Furthermore, in the hinge device according to the present invention, the projection is supported so as to protrude and retract in one of the hinge body and the hinge receiver, and the face material is not in a predetermined opening / closing position in the rotating mechanism. It is preferable that an immersion restriction means is provided for restricting the protrusion so as not to be immersed in the state.
According to such a configuration, the protrusions are immersed by the protrusion / subtraction support means so that the engagement with the recesses can be removed and the face material can be removed, and the protrusions are inserted after the protrusions are immersed. By projecting and engaging with the recess, the face material can be supported so as to be freely opened and closed. Then, in a state where the face material is not at the predetermined opening / closing position, the protrusions cannot be immersed by the immersion restricting means, so that the face material can be built and removed only when it is at the predetermined opening / closing position. Thus, for example, if the closing position of the face material is set as the predetermined opening / closing position, the protrusion is regulated to be non-immersible when the face material is opened other than the closed position, and the face material cannot be removed. Therefore, it is possible to prevent the face material from dropping unintentionally.

In the hinge device of the present invention, the hinge receiver has a long hole formed in an arc shape around the rotation center of the rotation mechanism, and is attached to the support by a fixing tool through the long hole. Preferably it is.
According to such a configuration, the hinge receiver is attached to the support body through the arc-shaped long hole, so that the attachment angle can be obtained simply by rotating the hinge receiver along the long hole after loosening the fixing tool. Can be adjusted. Therefore, since the mounting angle can be adjusted without completely removing the hinge receiver from the support, the adjustment work can be facilitated and the workability and maintainability can be further improved.

On the other hand, the joinery of the present invention includes a frame body as a support body, a face material provided inside the frame body, and any one of the hinge devices that supports the face material to the frame body so as to be opened and closed. The hinge device includes a hinge main body provided on the face material side and a hinge receiver provided on the support body side.
According to the present invention, the same effect as that of the hinge device can be obtained, the adjustment work of the opening angle of the face material can be easily performed, and workability and maintainability can be improved.

  According to the hinge device and joinery of the present invention as described above, the opening angle of the face material is finely adjusted by a relatively easy adjustment operation without altering the structure of the hinge device or adding or replacing parts. Therefore, workability and maintainability can be improved.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
As shown in FIG. 1, a door 1 as a fitting of the present invention is a fitting for a bathroom entrance that partitions a dressing room and a bathroom, for example, and includes an upper frame 2, a lower frame 3, and left and right vertical frames 4. A frame 5 (framework) as a frame (support) and a shoji 10 that is supported by the frame 5 and can be opened and closed on the bathroom side. The shoji 10 includes an upper collar 11, a lower collar 12, left and right vertical collars 13, and a resin panel 14 that is supported inside the four-sided frame. The shoji 10 is on one side (the right side in FIG. 1), and the upper and lower ends of the hanging rod 13A are rotatably supported by the upper frame 2 and the lower frame 3, respectively, and the other side (the left side in FIG. 1). The door side is configured to be openable toward the bathroom. And the upper end part of the vertical rod 13A on the suspension side is supported by the upper frame 2 by the hinge device 20, and the lower end portion of the vertical rod 13A is supported by the lower frame 3 by a normal hinge (not shown).

  As shown in FIG. 2, the hinge device 20 includes a hinge main body 21 provided on the vertical rod 13 </ b> A of the shoji 10 and a hinge receiver 22 provided on the bathroom-side bottom surface of the upper frame 2. As shown in FIGS. 3 and 4, the hinge body 21 includes a hinge case 23 as a rotation support portion fixed to the vertical rod 13 </ b> A, and a pivot 24 as a rotation member rotatably supported by the hinge case 23. And a coil spring 25 as urging means for urging the pivot 24 in a direction (upward) protruding from the hinge case 23. The hinge case 23 and the pivot 24 constitute a rotation mechanism, and a protrusion 241 protruding from the upper end of the pivot 24 is engaged with the recess 221 of the hinge receiver 22 so as not to rotate. Specifically, the protrusion 241, which is formed in the shape of a prism, and the concave portion 221, which is formed in the shape of a square hole, are engaged with each other so that the pivot 24 is engaged with the hinge receiver 22 in a non-rotatable manner. The shoji 10 is configured to be openable and closable by being supported rotatably on the hinge case 23.

  As shown in FIG. 5, the hinge case 23 has a generally cylindrical shape and a case main body 231 inserted into the vertical hook 13 </ b> A, and a fixed piece that extends laterally from the case main body 231 and is fixed to the upper hook 11. 232 and is formed as an integrally molded part made of resin. The case main body 231 is provided with a cylindrical inner peripheral surface 233 that rotatably supports the pivot 24, and an operation hole 234 for immersing the pivot 24 reaches the cylindrical inner peripheral surface 233 on the side surface of the case main body 231. Is formed. Further, as shown in FIG. 5, a through hole 131 is formed on the side surface of the dresser 13 </ b> A corresponding to the operation hole 234. Further, a locking hole 235 for locking the locking projection 245 of the pivot 24 is formed on the bottom surface of the case body 231. In addition, a restriction protrusion 236 serving as a rotation angle restricting means for restricting the rotation angle of the pivot 24 by being in contact with the contact portion 247 of the pivot 24 is provided on a part of the cylindrical inner peripheral surface 233.

  The pivot 24 has a substantially columnar shape, a pivot main body 242 inserted into the cylindrical inner peripheral surface 233 of the hinge case 23, the projection 241 protruding from the pivot main body 242, and a substantially disk-shaped provided below the pivot main body 242. It has a pivot operation part 243 and a pivot shaft part 244 that protrudes downward from the pivot operation part 243 and allows the coil spring 25 to pass therethrough, and is formed as an integrally molded part made of resin. A pair of locking projections 245 are formed at the tip of the pivot shaft portion 244, and the pivot 24 is incorporated into the hinge case 23 by locking these locking projections 245 into the locking holes 235 of the hinge case 23. It is like that. The pivot body 242 retreats inward from the outer peripheral surface thereof and allows the retraction portion 246 to pass through the restriction protrusion 236 of the hinge case 23, and can be brought into contact with the restriction protrusion 236 at the circumferential end of the retraction portion 246. A contact portion 247 is provided. Further, the pivot main body 242 is formed with a vertically retreating portion 248 that extends upward continuously from the retreating portion 246 and passes the restricting projection 236 up and down, and the retreating portion 246 at a position where the vertically retreating portion 248 is not formed, A step portion 249 is formed as an immersion restricting means that can come into contact with the restricting protrusion 236.

  In the hinge main body 21 described above, as shown in FIGS. 4 and 5, the pivot main body 242 of the pivot 24 is rotatably supported along the cylindrical inner peripheral surface 233 of the hinge case 23, and the hinge case 23 and the pivot 24 are supported. Are rotated relative to each other by a predetermined angle, the abutment portion 247 abuts against the regulating projection 236 to regulate the relative rotation angle. That is, since the pivot 24 is non-rotatably engaged with the hinge receiver 22 by the concave / convex fitting between the projection 241 and the concave portion 221, the pivot 24 does not rotate with respect to the joinery frame 5, and the hinge case 23 When the shoji 10 is opened to a predetermined opening position, the restricting projection 236 and the abutting portion 247 are brought into contact with each other, whereby the opening angle of the shoji 10 is regulated. As described above, the opening angle of the shoji 10 that is regulated by the hinge body 21 is set to 90 °, for example, and the regulating projection 236 and the contact portion 247 may be formed according to the set angle.

  Further, the vertically retreating portion 248 of the pivot 24 is formed at a position facing the restriction projection 236 of the hinge case 23 in a state where the shoji 10 is closed (a predetermined opening / closing position and an opening angle is 0 °). In this state, by pushing down the pivot 24 against the urging force of the coil spring 25, as shown in FIG. 5A, the restricting projection 236 passes through the up and down retreating portion 248, and the pivot 24 is hinge case. It is possible to immerse inside 23 (downward). Specifically, a tool is inserted into the operation hole 234 of the hinge case 23 from the through hole 131 of the vertical rod 13A, and the pivot operation unit 243 is hooked and pushed down with this tool, so that the pivot 24 is inserted into the hinge case 23. It has become so. Since the projection 241 is also lowered by the immersion of the pivot 24, the projection 241 is detached from the concave portion 221 of the hinge receiver 22, and the hinge body 21 and the shoji 10 can be detached from the hinge receiver 22.

  On the other hand, in the state where the shoji 10 is opened, the restricting projection 236 is disengaged from the vertical retreating portion 248 and is positioned below the stepped portion 249. Therefore, even if the pivot 24 is pushed down, the restricting projection 236 and the stepped portion 249 contact Accordingly, the immersion of the pivot 24 is restricted, so that the hinge body 21 and the shoji 10 cannot be removed from the hinge receiver 22. In this way, when the opening angle of the shoji 10 is other than 0 °, the pivot 24 cannot be immersed due to the contact between the restricting projection 236 and the step 249, and only when the shoji 10 is closed, Since the installation can be performed, it is possible to prevent the shoji 10 from falling off unintentionally during normal use. Further, when the shoji 10 is installed in the joinery frame 5, the vertical retreating portion 248 of the pivot 24 is aligned with the position facing the restriction projection 236 of the hinge case 23, and the pivot 24 is immersed in the hinge case 23 in this state. Then, by installing the shoji 10 at a position where the opening angle becomes 0 °, the setting of the rotation angle restriction by the restriction protrusion 236 and the contact portion 247 in the hinge body 21 can be appropriately reflected. It has become.

  As shown in FIGS. 2, 3, and 7, the hinge receiver 22 has two screws 223 as fixing tools attached to the back plate 222 inserted into the groove 2 </ b> A provided on the bottom surface of the bathroom 2 on the upper frame 2. The upper frame 2 is fixed by screwing. The hinge receiver 22 is formed with a pair of left and right elongated holes 224 through which the two screws 223 are inserted, and a contact protrusion 225 that protrudes from the upper surface of the hinge receiver 22 and is inserted into the groove 2A. The pair of long holes 224 are each formed in an arc shape around the center O of the protrusion 241 and the recess 221 that is the rotation center of the pivot 24. Such a hinge receiver 22 is configured to be rotatable around the center O by loosening two screws 223 and moving the long hole 224 along the screws 223. Therefore, by rotating the hinge receiver 22 and changing the attachment angle with respect to the upper frame 2, the angle of the recess 221, that is, the engagement angle with the protrusion 241 of the pivot 24 can be adjusted. Here, if the state shown in FIG. 7A is 0 °, the attachment angle is changed by, for example, 5 ° (−5 °) counterclockwise in FIG. 7B, and in FIG. For example, the mounting angle is changed by 5 ° (+ 5 °) clockwise. When the mounting angle of the hinge receiver 22 is changed in this way, the contact protrusion 225 contacts the edge of the groove 2A, so that the center O position of the recess 221 does not deviate from a predetermined rotation center. Can be done.

  By changing the mounting angle of the hinge receiver 22 in this way, when the opening angle of the shoji 10 due to the contact between the restriction projection 236 and the contact portion 247 in the hinge body 21 is set to 90 °, 85 is set. The opening angle of the shoji 10 can be adjusted in the range of from ° to 95 °. In this way, the attachment angle of the hinge receiver 22 can be adjusted, and the hinge receiver 22 is provided independently and in series with the opening angle setting mechanism (rotation angle regulating means) in the hinge body 21. There is no need to remove or disassemble from the shoji 10, modify or replace its parts, or adjust the restricting projection 236 or the abutting portion 247 of the hinge body 21, and the opening angle of the shoji 10 can be adjusted relatively easily. Can be adjusted. Moreover, since the mounting angle of the hinge receiver 22 can be adjusted by simply loosening the two screws 223 with the shoji 10 removed from the joinery frame 5 as described above, the adjustment work can be facilitated and workability and maintainability can be facilitated. Can be improved.
