Therefore, the prospective moving member 46 is moved to the outdoor side by operating the operation handle 8, but the longitudinal bone 3b does not move. Moved and drawn. Further, when the operation handle 8 is moved to the release position, the claw portion 46b moves to the indoor side, and the pulling of the summoning bowl 12 and the vertical bone 3b is released.

  In this way, by operating the operation handle 8, the shoji 10 can be locked and the movement of the shoji 10 can be restricted, and the summing bar 12 can be pulled toward the longitudinal bone 3b.

  The opening width restriction mechanism 50 is provided on the upper side of the lock mechanism 60. The opening width restriction mechanism 50 includes a hook mechanism 51 provided in the door-end fence 11 and an engagement link mechanism 56 that is provided in the left vertical frame 3e and engages with the hook mechanism 51.

  As shown in FIG. 11, the heel mechanism 51 is provided on the door rod 11 with a release lever 9 smaller than the operation handle 8 and coaxial with the release lever 9, and a release plate that rotates integrally with the release lever 9. 52, a release moving plate 53 that is moved up and down by the release plate 52, a release guide plate 54 that is fixed to the door rod 11 and guides the movement of the release movement plate 53, and is fixed to the release movement plate 53. And a hook member 55 as an engaging portion.

  The unlocking lever 9 switches between an engaged state in which the flange member 55 is engaged with the engagement link mechanism 56 and a release state in which the engagement between the flange member 55 and the engagement link mechanism 56 is released. It is a lever.

  For example, by first operating the release lever 9, the hook mechanism 51 rotates the release plate 52 that rotates together with the release lever 9, and engages with the release plate 52 as the release plate 52 rotates. The release moving plate 53 and the connecting plate 49 coupled to the release moving plate 53 with screws are moved up and down.

  On the surface along the prospective direction of the connecting plate 49, a flange member 55 is provided so as to be movable in the vertical direction, and is urged by a tension coil spring 70 from above. That is, the hook member 55 is positioned by the tension coil spring 70 at an engagement position that is normally at the upper end side in the vertical movement range, and when the release lever 9 is operated in the release direction, or the hook member 55 When a force that pushes down the lever 55 moves downward and is positioned at the release position and the release lever 9 is operated in the engagement direction, or when the force that pushes down the flange member 55 is removed It is configured to be located at the engagement position on the upper end side in the vertical movement range.

  The eaves member 55 includes a fixing portion 55a having a substantially U-shaped horizontal section, reinforcing portions 55b protruding from both ends in the prospective direction of the fixing portion 55a, and engaging pins 59c of the engaging link mechanism 56. And a flange portion 55c that engages with. The flange portion 55c has a flange piece 55d as an engagement piece spaced from the fixed portion 55a. That is, the flange member 55 has a gap opened upward between the fixing portion 55a and the flange piece 55d. In addition, an inclined portion 55e that is inclined downward toward the vertical frame 3e side is provided on the vertical frame 3e side at the upper end portion of the flange piece 55d.

  Then, when the release lever 9 is rotated in the release direction, the release movement plate 53 is moved downward, the flange member 55 is positioned at the lower end side of the movement range, and the release lever 9 is rotated in the engagement direction. The release moving plate 53 is sometimes moved upward so that the flange member 55 is positioned on the upper end side of the moving range.

The engagement link mechanism 56 is provided in the holding member 57 provided in the receiving portion 3g of the left vertical frame 3e in which the door rod 11 of the shoji 10 is accommodated when the shoji 10 is closed, and the holding member 57. A proximal link 58 on which the proximal end 58a side is rotatably supported around the shaft 56a, and a distal link 59 having one end 59a rotatably attached to the distal end 58b of the proximal link 58; It has an engagement pin 59c provided along the prospective direction at the distal end portion 59b which is the other end portion of the distal end link 59. Here, the base end link 58 rotatably supported by the holding member 57 and the front end link 59 rotatably supported by the base end link 58 correspond to the rotating member. Also,
In this embodiment, when the shoji 10 is closed in the housing 3g of the left vertical frame 3e provided with the base end link 58 and the tip link 59 as rotating members, the door toe 11 of the shoji 10 is closed. Corresponding to one of the housing 3g and the door rod 11 of the vertical frame 3e to be accommodated, the inside of the door rod 11 provided with the hook member 55 as an engaging portion is the vertical frame 3. This corresponds to the other part of the inside of the housing part 3g and the inside of the door rod 11.

  In the engaging link mechanism 56, the rotation support part of the holding member 57 and the proximal link 58 and the distal end of the distal link 59 are on the upper side, and the rotational support part of the proximal link 58 and the distal link 59 is on the lower side. It is folded so as to be accommodated in the accommodating portion 3g of the vertical frame 3e. Further, as shown in FIG. 12, when the distal end portion 59b side of the distal end link 59 is pulled out to the side of the summoning cage 12, the proximal end link 58 rotates around the shaft 56a, and the distal end link 59 becomes the proximal end link. It is configured to protrude from the vertical frame 3e while being rotated with respect to 58 and extend in the direction of finding.

  When the release lever 9 is positioned at the engagement position with the shoji 10 closed, the opening width regulating mechanism 50 is engaged with the engagement pin 59c of the engagement link mechanism 56 in the gap of the flange member 55 as shown in FIG. Therefore, when the shoji 10 is opened in this state, the engagement pin 59c is pulled by the collar piece 55d and the proximal end link 58 and the distal end link 59 are extended in the direction of finding, and the proximal end link 58 and the distal end link are extended. 59 is extended, the movement of the shoji 10 in the right direction, that is, in the opening direction is restricted. In other words, the opening width is regulated by regulating the amount of movement of the shoji 10 by the opening width regulating mechanism 50 to the position where the proximal end link 58 and the distal end link 59 are extended.

  On the other hand, when the release lever 9 is positioned at the release position with the shoji 10 closed, as shown in FIG. 14, the collar member 55 is positioned below the movement range and the engagement pin of the engagement link mechanism 56 is engaged. Since 59c is located outside the gap of the eaves member 55, even if the shoji 10 is opened in this state, the engagement pin 59c is not pulled by the eaves piece 55d, and the movement of the shoji 10 in the right direction is not restricted.

  Further, when the release lever 9 is located at the engagement position with the shoji 10 opened, when the shoji 10 is closed, as shown in FIG. 15, the eaves member 55 provided on the door toe 11 moves within the moving range. The vertical frame 3e is approached while being positioned on the upper end side of the. When the shoji 10 is closed, the inclined portion 55e of the collar piece 55d contacts the engagement pin 59c of the folded engagement link mechanism 56 on the vertical frame 3e side.

  Further, when the shoji 10 is closed, the hook member 55 is pressed downward by the engagement pin 59c, and thus the hook member 55 moves downward while extending the tension coil spring 70. When the collar piece 55d moves to the left side of the engagement pin 59c, that is, between the engagement pin 59c and the portion where the engagement link mechanism 56 of the vertical frame 3e is fixed, the tension coil spring 70 causes the collar member to move. 55 is pulled up, and the engaging pin 59 c enters the gap of the flange member 55. When the shoji 10 is opened in this state, the engaging pin 59c is pulled by the collar piece 55d, the proximal link 58 and the distal link 59 are extended in the direction of finding, and the proximal link 58 and the distal link 59 are expanded. In the state, the rightward movement of the shoji 10 is restricted.

  According to the joinery 1 of the present embodiment, the amount of movement of the shoji 10 in the opening direction is restricted by the engagement of the engagement pin 59c of the engagement link mechanism 56 and the collar piece 55d. At this time, the eaves member 55 having the eaves piece 55d is provided in the door end eave 11 of the shoji 10, and the proximal end link 58, the distal end link 59, and the engagement pin 59c of the engagement link mechanism 56 are provided on the vertical frame 3e. It rotates about a shaft 56a provided in the housing 3g, and protrudes from the vertical frame 3e while engaging with the collar piece 55d when the shoji 10 is opened, so that it is engaged when the shoji 10 is closed. The link mechanism 56 and the flange member 55 are not exposed to the outside. For this reason, it is possible to provide the fitting 1 provided with the opening width regulating mechanism 50 that regulates the movement amount of the shoji 10, that is, the opening width, without impairing the beauty of the fitting 1.

  Further, by operating the release lever 9, an engagement state in which the hook piece 55d is engaged with the engagement pin 59c, and a release state in which the engagement between the hook piece 55d and the engagement pin 59c is released. It is possible to switch easily. That is, the engagement link mechanism 56 and the flange member 55 that are not exposed to the outside can be easily engaged and released.

  Further, the front end of the engaging link mechanism 56 protruding from the vertical frame 3e, that is, the engaging pin 59c provided at the front end of the front end link 59 is provided along the prospective direction, and the shoji 10 is closed. In this state, when the release lever 9 is operated from the released state to the engaged state, the collar member 55 moves and the collar piece 55d and the engagement pin 59c are engaged, so that the collar piece 55d becomes the collar piece 55d. When the shoji 10 is opened in a state where is engaged, the movement amount of the shoji 10, that is, the opening width can be reliably regulated.

  Further, since the collar member 55 is urged so as to be movable to the release position and is positioned at the engagement position, the shoji 10 is opened without the engagement between the collar piece 55d of the collar member 55 and the engagement pin 59c. By closing the shoji 10 from above, it is possible to move the hook member 55 to the release position side and engage the hook piece 55d with the engaging pin 59c. For this reason, the operator can close the shoji 10 regardless of the position of the collar member 55.

  Further, by operating the operation handle 8, the pressing piece 31 protruding upward and downward of the shoji 10 and the rail 4 for guiding the shoji 10 are engaged, so that the shoji 10 can be maintained in an open state. is there. In particular, the pressing piece 31 engages with the rail 4 connected in the direction in which the shoji 10 moves, so that the shoji 10 can be kept open with a desired opening width.

  Further, since the operation handle 8 is operated together with the switching operation portion 62d for switching the engagement between the pressing piece 31 and the rail 4 to a state where the engagement can be released and the state where the pressing piece 31 cannot be released, the pressing piece 31 and the rail 4 are engaged. The shoji 10 cannot be locked simply by operating the operation handle 8. For this reason, for example, it is possible to prevent an infant or the like from locking the shoji 10 by mistake.

  If the locking mechanism 20 is provided on the door end side, the airtightness on the side of the summoning basket 12 may be lowered. However, according to the fitting 1 as described above, when the shoji 10 is closed, the summoning is performed. The claw portion 46b that protrudes indoors from the heel 12 is positioned on the indoor side of the smoke return 3f of the vertical bone 3b and engages with the smoke return 3f, and the claw portion 46b moves to the outdoor side by operating the operation handle 8. As a result, the summoning bowl 12 is drawn toward the longitudinal bone 3b, so that the airtightness of the summoning bowl 12 can be ensured. At this time, since only the operation handle 8 is operated by the operator, it is possible to provide the joinery 1 excellent in operability, in which the airtightness on the side of the summoning basket 12 is ensured only by locking.

  In the above-described embodiment, the case 1 for a sliding window having a single shoji 10 has been described as an example. However, for example, a sliding window fitting or a drawing window fitting may be used.

  In the above embodiment, the base end link 58 and the front end link 59 as the rotating members are in the accommodating portion 3g of the left vertical frame 3e, and the flange member 55 as the engaging portion is in the door-end rod 11, Although the provided example was demonstrated, the base end link 58 and the front-end | tip link 59 may be the form provided in the door-end ledge 11, and the eaves member 55 is provided in the accommodating part 3g of the vertical frame 3e.
