  By the way, in the opening degree control apparatus proposed in Patent Document 1 described above, the shoji is only allowed to be in a half-open state or a full-open state in accordance with the operation of the operation unit, so that the shoji is held in a fully closed state. In order to do so, a separate locking / unlocking device was required. That is, when the user adjusts the shoji to either the half-open state or the fully-open state, the user operates the operation unit of the opening degree regulating device, and when holding the shoji in the fully-closed state, It is necessary to operate the operation unit, and there is a possibility that the operation becomes complicated. Further, since the locking / unlocking device is required in addition to the opening degree regulating device, there is a possibility that the manufacturing cost increases due to an increase in the number of parts.

  In view of the above circumstances, an object of the present invention is to provide an opening degree regulating device and a fitting capable of improving the operability while reducing the manufacturing cost.

In order to achieve the above object, an opening degree regulating device according to the present invention includes an arm supported rotatably on one of an opening frame and a face member provided so as to be openable and closable with respect to the opening frame, A receiving member disposed on the other of the opening frame and the face material and having a guide groove into which the pin provided in the arm can enter, and when the pin enters the guide groove, the pin moves open. In the opening degree regulating device that restricts the opening of the facing material to a predetermined size, while allowing the facing material to be opened to be fully opened when the pin is detached from the guide groove The arm is supported and slid according to the operation of the operation unit, and when the face material is located at the reference position in the fully closed state, the pin is caused to enter the guide groove, First advance position from the reference position when the face material is fully closed A slide member for detaching the pin from the guide groove when the slide member is moved to the second position, and a slide member when the slide member is slid from the reference position to the second advanced position when the face member is fully closed. and a disposed a lock pin is advanced into the lock grooves of the opening frame and the lock receiving member disposed on the other of said face member and a lock mechanism for holding the face member in a fully closed state, the slide The member is normally urged by the urging means and positioned at the reference position, and normally the state that the pin of the arm supported by the slide member positioned at the reference position has entered the guide groove is maintained. On the other hand, if the slide member is slid from the reference position to the first advanced position against the urging force of the urging means by operating the operating portion with the face material fully closed, The pin is maintained in a state of being detached from the guide groove, and the slide member is allowed to return to the reference position by the urging means after the face material is opened and before it is fully closed again. And a return mechanism that allows the pin to enter the guide groove when the face material is fully closed again, and the lock mechanism is configured such that the slide member moves the biasing means according to the operation of the operation portion. A sliding movement is allowed between the reference position and the second advance position regardless of the urging force .

  According to the present invention, when the face member is in the fully closed state and the slide member is positioned at the reference position, the pin is inserted into the guide groove, so that the surface can be set by operating the operating portion to position the slide member at the reference position. When the material moves open, it can be in a half-open state in which the opening degree is regulated to a predetermined size. Further, when the face member is fully closed and the slide member slides from the reference position to the first advanced position, the pin is removed from the guide groove, so that the operating member is operated to position the slide member at the first advanced position. By doing so, the face material that moves open can be fully opened. Further, when the lock member is slid and moved from the reference position to the second advanced position when the face member is fully closed, the lock pin disposed on the slide member is disposed on the other of the opening frame and the face member. Since the face material is held in the fully closed state by entering the lock groove of the provided lock receiving member, the lock pin is locked to the lock receiving member by operating the operating portion to position the slide member at the second advanced position. The face material can be held in a fully closed state by entering the groove. That is, it is possible to alternatively select whether the face material is in a half-open state, a full-open state, or a fully-closed state by operating the operation unit.

  According to the present invention, the return mechanism normally maintains the state where the arm pin supported by the slide member positioned at the reference position enters the guide groove, while the face member is fully closed and the operation portion is operated. Thus, when the slide member moves from the reference position to the first advanced position against the urging force of the urging means, the pin is maintained in a state of being detached from the guide groove, and then the face material is opened and moved. Since the slide member is allowed to return to the reference position by the urging means during the period from when it is again fully closed to when the face material is again fully closed, the pin enters the guide groove. When the material is to be fully opened, it is not necessary to maintain the operation of the operation unit once the operation unit is operated and the slide member is positioned at the first advanced position, and the face material can be easily fully opened. If the face material is then closed and moved, It is possible to the initial state to.

  Further, in the opening degree regulating device according to the present invention, the return mechanism is provided so as to close an open end of the guide groove, and the slide member is moved from the reference position when the face material is fully closed. When sliding to the first advancing position, the pin gets over the pin and locks with the pin to keep the pin detached from the guide groove. After that, the face material opens and moves again. It is provided in the vicinity of the end of the guide groove, and a locking member that releases the locking state with the pin until it is fully closed and allows the slide member to move to the reference position. An inclined guide that allows the pin, which has been released from the locking state with the locking member, to enter the guide groove by sliding on the inclined surface when the face material is fully closed again. And a section.

  According to this invention, when the face member is in the fully closed state and the slide member slides from the reference position to the first advanced position, the pin gets over the pin and locks with the pin. Is maintained in the state where it is detached from the guide groove, and after that, the state in which the pin is locked is released and the slide member moves to the reference position between the time when the face material is opened and before it is fully closed again. When the slope guide part is allowed and the face material is fully closed again, the pin that has released the locking state with the locking member enters the guide groove by sliding on its inclined surface. Therefore, when the face material is fully opened, it is not necessary to maintain the operation of the operation unit once the operation unit is operated and the slide member is positioned at the first advanced position. Then, the face material can be easily opened fully, and then the initial state can be easily obtained by closing the face material.

  In the opening degree regulating device according to the present invention, the lock mechanism includes a guide member that is locked to one end of the urging unit and has a long hole-shaped guide hole, and is connected to the slide member. The sliding member moves along the longitudinal direction of the guide hole while passing through the guide hole, thereby allowing the slide member to slide between the reference position and the second advanced position. It is characterized by that.

  According to this invention, the guide member allows the slide member to slide between the reference position and the second advanced position, so that the operating portion is temporarily operated to position the slide member at the second advanced position. Then, the lock pin can enter the lock groove of the lock receiving member to hold the face material in the fully closed state.

  In addition, a fitting according to the present invention is characterized in that the fitting includes an opening frame and a face member provided so as to be openable and closable with respect to the opening frame.

  According to this invention, since the joinery includes the opening degree regulating device, the opening degree of the face material that moves open by operating the operation unit and positioning the slide member at the reference position is a predetermined size. The face material that is opened and moved can be brought into a fully opened state by operating the operating portion to position the slide member at the first advanced position. Further, by operating the operating portion to position the slide member at the second advanced position, the lock pin can enter the lock groove of the lock receiving member and the face material can be held in the fully closed state.

  According to the present invention, since the face material can be selectively selected from the half-open state, the fully-open state, and the fully-closed state by the operation of the operation unit, the operability can be improved. it can. In addition, a separate locking / unlocking device is not required as in the prior art, and the number of parts can be reduced by sharing the operation unit. Therefore, there is an effect that the operability can be improved while the manufacturing cost is reduced.

In addition, a resin spring 82 that is bifurcated downward is attached to the inside of the lock receiving member 80 via a resin spring pin 83.

  In the joinery having the above-described configuration, the opening degree regulating device 30 regulates the opening movement of the shoji 20 as follows.

  FIG. 5 shows the opening degree regulating device 30 when the shoji 20 is in a fully closed state, where (a) is an explanatory view showing a state seen from the shoji 20 side, and (b) is a view seen from the indoor side. It is explanatory drawing which shows. In the present specification, the “fully closed state” is a state in which the shoji 20 completely closes the opening (window) formed by the opening frame 10 and cannot be moved any further. The “fully open state” means a state in which the open movement has been made to the limit position of the allowable open movement and no further open movement can be made.

  As shown in FIG. 5, when the shoji 20 is in the fully closed state, the slider 52 is located at the reference position, and the arm tip pin 41 of the arm 40 enters the guide groove 71 of the receiving member 70. . After the operating handle 1 is operated and unlocked in such a state, when the shoji 20 is moved open, the arm 40 is rotated around the central axis of the arm shaft pin 44 as the shoji 20 is opened. Then, the arm tip pin 41 moves along the longitudinal direction of the guide groove 71. The movement of the arm 40 is restricted by the arm tip pin 41 coming into contact with the upper end edge of the guide groove 71, whereby the opening movement of the shoji 20 is also restricted and the arm is in a half-open state.

  That is, in the joinery (opening restriction device 30) according to the present embodiment, when the arm tip pin 41 of the arm 40 enters the guide groove 71, the opening degree of the shoji 20 is opened in advance when the shoji 20 is opened. It can be in a half-open state that is regulated to a predetermined size.

  Next, as shown in FIGS. 6 and 7, when the knob 60 is pressed downward while the shoji 20 is in the fully closed state, the slider 52 is attached to the slide spring 53 via the guide member 54. Slides down against the forces. That is, the slider 52 slides downward against the urging force of the slide spring 53 by pulling the guide member 54 downward with the connecting pin 56 in contact with the lower edge of the guide hole 54a. Moving. With this downward sliding movement, the arm tip pin 41 of the arm 40 slides on the downwardly inclined surface 73 a of the locking member 72 that closes the open end of the guide groove 71. Thereafter, when the slider 52 that slides is positioned at the first advanced position, the arm tip pin 41 of the arm 40 gets over the downwardly inclined surface 73a and the urging force of the slide spring 53 also acts to engage the locking member 72 (engagement). Locking to the stop 73). Accordingly, the slider 52 is maintained at the first advanced position, and the arm tip pin 41 of the arm 40 is maintained in a state of being detached from the guide groove 71.

  After the operation handle 1 is operated and unlocked in the state where the slider 52 is maintained at the first advanced position as described above, when the shoji 20 in the fully closed state is opened as shown in FIG. The locking state between the stop member 72 and the arm tip pin 41 is released, and the slider 52 slides upward by the urging force of the slide spring 53 and returns to the reference position.

  By the way, since the arm tip pin 41 of the arm 40 has already detached from the guide groove 71, the arm 40 does not rotate even when the shoji 20 is opened, and the shoji 20 can be fully opened. In other words, in the joinery (opening restriction device 30) according to the present embodiment, when the arm tip pin 41 of the arm 40 is detached from the guide groove 71, the opening shoji 20 is allowed to be fully opened. doing.

  When the shoji 20 that has been fully opened in this way is closed, the receiving member 70 provided on the right vertical rod 24 of the shoji 20 approaches the arm 40 provided on the right vertical frame 14 as shown in FIG. As shown in FIGS. 10 and 11, the arm tip pin 41 of the arm 40 slides on the guide inclined surface 74 a of the inclined guide portion 74 formed on the receiving member 70 as the shoji 20 is closed. When the shoji 20 is in the fully closed state, as shown in FIG. 12, the arm tip pin 41 gets over the guide inclined surface 74a and enters the guide groove 71 from the enlarged diameter portion 71a, to the state shown in FIG. Return.

  On the other hand, as shown in FIGS. 13 and 14, when the knob 60 is pressed upward while the shoji 20 is in the fully closed state, the slider 52 slides upward as follows. . That is, the slider 52 slides upward regardless of the urging force of the slide spring 53 when the connecting pin 56 moves the guide hole 54a of the guide member 54 from the lower end portion toward the upper end portion. By this upward sliding movement, the lock pin 57 of the slider 52 enters the lock groove 81 from the lower end of the lock groove 81 of the lock receiving member 80. Thereafter, the slider 52 that slides is positioned at the second advanced position, whereby the lock pin 57 of the slider 52 reaches the upper end of the lock groove 81 and is locked at the upper end by the elastic restoring force of the resin spring 82. .

  Thus, when the lock pin 57 enters and is locked into the lock groove 81, the shoji 20 is restricted from moving open even if the operation handle 1 is operated, and the shoji 20 is held in the fully closed state. The fully closed state is released by releasing the lock pin 57 from the lock groove 81 when the knob 60 is pressed downward and the slider 52 returns from the second advanced position to the reference position.

  By the way, as described above, the knob 60 is biased by the leaf spring 63 so as to rotate to the outdoor side around the contact portion 64 between the base end edge of the knob base 61 and the knob base 527. However, when the shoji 20 is in the fully closed state, as shown in FIG. 15, the inner side surface of the knob base 61 is pushed to the indoor side by the right vertical rod 24 of the shoji 20, and the right vertical frame 14. Is kept in contact with the AT material 14a provided in the airtightness. In this way, when the shoji 20 is in the fully closed state, the knob 60 is pressed downward or upward as shown in FIG. 16, but this pressing operation is performed manually.

  Then, when the shoji 20 is moved open, as shown in FIG. 17, the knob 60 is biased by the leaf spring 63 to center the contact portion 64 between the base end edge of the knob base 61 and the knob base 527. As a result, the contact area of the right vertical frame 14 with the AT material 14a can be reduced. As a result, as shown in FIG. 18, the slider base 61 and the AT material 14a slide when the slider 52 located at the first advance position slides upward toward the reference position by the biasing force of the slide spring 53. The resistance can be reduced, and the slider 52 can be favorably moved toward the reference position.

  As described above, in the joinery (opening restriction device 30) according to the present embodiment, the locking member 72 and the inclination guide portion 74 are normally provided on the arm 40 supported by the slider 52 located at the reference position. While the arm tip pin 41 is maintained in the state of entering the guide groove 71, the slider 52 is first operated from the reference position against the urging force of the slide spring 53 by operating the knob 60 with the shoji 20 fully closed. When moving to the advanced position, the arm tip pin 41 is maintained in a state of being detached from the guide groove 71, and then the slider 52 is moved to the slide spring 53 after the shoji 20 is moved to the fully closed state. Thus, the return mechanism is configured to allow the arm tip pin 41 to enter the guide groove 71 when the shoji 20 is fully closed again by allowing the return to the reference position. Further, the guide member 54 allows the slider 52 to slide between the reference position and the second advanced position regardless of the urging force of the slide spring 53 in accordance with the operation of the knob 60, and the shoji 20 is fully moved. When the slider 52 slides to the second advanced position in the closed state, the lock pin 57 disposed on the slider 52 is caused to enter the lock groove 81 of the lock receiving member 80 to hold the shoji 20 in the fully closed state. The lock mechanism is configured.

  And according to the fitting (opening control apparatus 30) which is this Embodiment, the opening degree is beforehand set when the shoji 20 moves open by operating the knob 60 to position the slider 52 at the reference position. The sliding door 20 can be fully opened by moving the slider 52 to the first advanced position by operating the knob 60. The shoji 20 can be fully opened. . Further, by operating the knob 60 to position the slider 52 at the second advanced position, the lock pin 57 can enter the lock groove 81 of the lock receiving member 80 to hold the shoji 20 in the fully closed state. That is, by operating the knob 60, it is possible to selectively select the shoji 20 to be in a half-open state, a full-open state, or a fully-closed state, and operability can be improved. In addition, a separate locking / unlocking device is not required as in the prior art, and the number of parts can be reduced by sharing the knob 60 or the like. Therefore, it is possible to improve the operability while reducing the manufacturing cost. In particular, since it is not necessary to provide a plurality of knobs 60, the design can be improved, and the shoji 20 can be held in the fully closed state only by operating the knob 60, so that the crime prevention can be improved. it can.

  According to the joinery (opening restriction device 30), when the locking member 72 is in the fully closed state and the slider 52 slides from the reference position to the first advanced position, the arm tip pin 41 holds itself. The arm tip pin 41 is engaged with the arm tip pin 41 and the arm tip pin 41 is disengaged from the guide groove 71, and then the arm 20 is moved between the opening of the shoji 20 and the fully closed state again. The slider 52 is allowed to move to the reference position by releasing the locked state with the tip pin 41, and the inclined guide portion 74 is connected to the locking member 72 when the shoji 20 is fully closed again. Since the arm tip pin 41 that has been released from the locked state is allowed to enter the guide groove 71 by sliding on its own inclined guide surface 74a, when the shoji 20 is fully opened, the knob 60 is Once operated The Ida 52 do not need to maintain the operation of when knob 60 brought into position in the first advanced position. Then, the shoji 20 can be easily fully opened by operating only the operation handle 1, and then the initial state can be easily obtained by closing the shoji 20. Therefore, the operation of bringing the shoji 20 into the fully open state can be facilitated. Moreover, since the guide member 54 allows the slider 52 to slide between the reference position and the second advanced position, the guide member 54 is locked once the knob 60 is operated to position the slider 52 at the second advanced position. The pin 57 can enter the lock groove 81 of the lock receiving member 80 to hold the shoji 20 in the fully closed state. Therefore, the operation of holding the shoji 20 in the fully closed state can be easily performed.

  According to the joinery (opening restriction device 30), the knob 60 is biased by the leaf spring 63, so that the outdoor side is centered on the contact portion 64 between the base end edge of the knob base 61 and the knob base 527. Therefore, when the shoji 20 is moved open, the contact area of the right vertical frame 14 with the AT material 14a can be reduced, and the slider 52 can be satisfactorily directed toward the reference position. By moving it, it can be surely positioned at the reference position. Accordingly, when the slider 52 is moved to the first advanced position and then the shoji 20 is opened and then closed, the arm tip pin 41 can be caused to enter the guide groove 71. In addition, when the shoji 20 opens again, the opening degree of the product can be regulated, and it is possible to reliably avoid the shoji 20 from being fully opened unexpectedly.

  Although the preferred embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made.

  In the embodiment described above, the slider 52 is urged by the slide spring 53 and is normally positioned at the reference position. However, in the present invention, the slide member is urged by the urging means. There is no need to be, and it may be located at any of the reference position, the first advance position, and the second advance position according to the operation of the operation unit.

  In the embodiment described above, the arm 40 is provided on the opening frame 10 and the receiving member 70 and the lock receiving member 80 are provided on the shoji 20, but in the present invention, the arm is provided on the shoji. The receiving member and the lock receiving member may be provided in the opening frame. Even with such a configuration, the same effects as those of the above-described embodiment can be obtained.

  In the embodiment described above, the slider 52 is slid from the reference position to the first advanced position by pressing the knob 60 downward, and the slider 52 is pressed by pressing the knob 60 upward. In the present invention, the first advance position is lower than the reference position and the second advance position is not limited to be higher than the reference position.

  In the above-described embodiment, the knob 60 is biased by the leaf spring 63 so that the knob 60 is rotated to the outdoor side around the contact portion 64 between the base edge of the knob base 61 and the knob base 527. However, in the present invention, even if such a leaf spring is not interposed, for example, the knob can be bent by bending the knob base. It may be assumed that the posture is displaced.
