Description

  The present invention relates to an intermediate operating device and a joinery for operating an open / close control mechanism linked to a movable element by moving the movable element relative to the apparatus body when a handle is operated.

  In the joinery, by operating a handle provided on the shoji, the shoji can be opened about the axis along the vertical direction, and the shoji is centered on the axis along the left-right direction. There is what is referred to as a so-called drake window that is configured to switch to a second support state that can be opened. In this type of joinery, an intermediate operation device is provided between the opening / closing control mechanism that supports the shoji with respect to the frame and the handle. The intermediate actuating device includes an apparatus main body and a movable element arranged to be movable with respect to the apparatus main body, and is configured such that the movable element moves relative to the apparatus main body when the handle is operated. Has been.

  In this intermediate actuator, for example, when the handle is rotated by 90 ° with the shoji being closed, the movable element moves by a distance corresponding to 90 ° with respect to the apparatus main body. As a result, the opening / closing control mechanism linked to the movable element is in the first support state, and the shoji can be opened indoors around the axis along the vertical direction (inward opening). On the other hand, when the handle is rotated 180 ° with the shoji screen closed, the movable element moves by a distance corresponding to 180 ° with respect to the apparatus main body. As a result, the open / close control mechanism is in the second support state, and the shoji can be opened so as to be tilted indoors about the axial center along the left-right direction (inward).

  Normally, in this type of joinery, a trigger member is provided in the intermediate operating device so that the movable element does not move when the shoji is open. The trigger member is disposed in the apparatus main body so as to be displaced between a state engaged with a notch provided in the movable element and a state disengaged. Between the apparatus main body and the trigger member, there is provided a spring member that urges the trigger member so as to be always engaged with the notch of the movable element. Further, the trigger member is provided with a contact portion that moves to a position where the trigger member is disengaged against the urging force of the spring member by contacting the frame when the shoji is closed.

  According to the joinery provided with such an intermediate operating device, when the shoji is open, the trigger member is disposed at the engagement position by the biasing force of the spring member, and is engaged with the notch of the movable element. Therefore, even if it is attempted to operate the handle while the shoji is open, the movable element cannot be moved relative to the apparatus body, and the support state of the opening / closing control mechanism is not changed. On the other hand, when the shoji is closed, the abutting portion of the trigger member abuts on the frame body, thereby deviating from the notch of the movable element to be in the disengaged position. Therefore, if the handle is operated, the movable element can be moved with respect to the apparatus main body, and the support state by the opening / closing control mechanism can be changed (for example, see Patent Document 1).

JP-A-2006-75029

  According to the intermediate operating device including the trigger member described above, the movable element can be moved only when the shoji is closed, so that the support state is not changed when the shoji is open. Moreover, if the shoji is opened, the trigger member automatically moves to the engaging position by the biasing force of the spring member, and if the shoji is closed, the trigger member becomes the non-engaging position, so there is no need to operate the trigger member, There is no risk of opening and closing the shoji.

  Here, the abutting portion of the trigger member mentioned above abuts on the frame body every time the shoji is opened and closed.

As shown in FIG. 14, trigger springs 446 are respectively provided between the main body cover 422 and the spring receiving portion 442 of the trigger member 440 in the trigger accommodating portion 425. The trigger spring 446 constantly biases the trigger member 440 to the outside of the apparatus main body 420 and presses the engaging protrusion 443 exposed to the outside of the apparatus main body 420 against the side edge of the slide block 410. The trigger member 440 pressed by the trigger spring 446 can engage with any one of the three trigger engagement grooves 411 a, 411 b, and 411 c provided on the slide block 410. When the engagement protrusion 443 of the trigger member 440 is engaged with any of the trigger engagement grooves 411a, 411b, and 411c, the relative movement of the slide block 410 with respect to the apparatus main body 420 is prevented.

  As is clear from FIG. 14A, the engagement piece 444 of the trigger member 440 protrudes outward from the slide block 410 and is shown in FIG. 14B when the shoji 20 is closed. Thus, it is comprised so that the contact surface of the door-end frame 14 may be contact | abutted. When the engagement piece portion 444 comes into contact with the finding surface of the door frame 14, the trigger member 440 moves indoors against the pressing force of the trigger spring 446, and the engagement protrusion 443 is formed on the slide block 410. The trigger engagement grooves 411a, 411b, and 411c are not engaged.

  As shown in FIG. 16, the intermediate operating device 400 having the above-described configuration is configured such that the slide block 410 extends in the vertical direction on the prospective surface of the door toe 25 and the apparatus main body 420 is accommodated in the door toe 25. It is attached to the door toe 25 in the state. In the intermediate operating device 400, the slide block 410 is disposed at the uppermost position with respect to the apparatus main body 420, and the engagement protrusion 443 of the trigger member 440 is engaged with the lowermost trigger engagement groove 411a of the slide block 410. Locked position. The handle 401 is attached to the door toe 25 of the shoji 20 so that the tip is directed vertically downward when the intermediate actuator 400 is in the locked position.

  In this state, when the engagement protrusion 443 of the trigger member 440 is deviated from the trigger engagement groove 411a against the pressing force of the trigger spring 446 and the handle 401 is disposed at the inward opening position, the slide block 410 is moved downward. In order to slide, the engagement protrusion 443 can be engaged with the central trigger engagement groove 411b, and when the handle 401 is further disposed in the inward position, the slide block 410 slides further downward, and the engagement protrusion 443 Can engage with the upper trigger engagement groove 411c.

  In the joinery having the above-described configuration, when the handle 401 is disposed at the locking position, the slide block 410 is disposed at the uppermost position with respect to the door-end fence 25 as illustrated in FIGS. 4 and 5. At this time, the upper link mechanism 240 is locked by the lock link 243, and the link lock pin 241 c of the main link 241 is accommodated in the pin receiving groove 246 a of the pin holder 246. The posture is maintained along the direction. The locking rod 310 of the locking device 300 has a lower end portion that deviates from the rod insertion hole 331 of the lower block member 330, and the lock pin 311 is disposed at a position facing the lock receiver 321. In this state, even when the shoji 20 is pulled indoors via the handle 401, the lock pin 311 comes into contact with the lock receiver 321, so the shoji 20 cannot be opened.

  When the handle 401 is rotated by 90 ° from the above-mentioned locking position and arranged at the inward opening position, the slide block 410 slides downward with respect to the door-end rod 25 as shown in FIG. Each member 402 slides downward. At this time, in the upper link mechanism 240, although the lock link 243 slides to the door end side via the corner drive 500, the lock state is still maintained. In the locking device 300, the lock pin 311 is arranged at a position not facing the lock receiver 321 by sliding the locking rod 310 downward. The lower end portion of the locking rod 310 deviates from the rod insertion hole 331 of the lower block member 330. Therefore, in this state, when the shoji 20 is pulled to the indoor side via the handle 401, the door-end fence 25 can be separated from the door-end frame 14, and as shown in FIG. The shoji 20 can be opened indoors with the upper hinge shaft 210 of 200 and the lower hinge shaft 110 of the lower hinge device 100 as the axis (inward opening of the shoji 20). When the shoji 20 is opened to the indoor side, the engagement piece 444 is separated from the finding surface of the door frame 14, so that the trigger member 440 moves to the outdoor side by the pressing force of the trigger spring 446 in the intermediate operating device 400. Then, the engagement protrusion 443 is maintained in a state of being engaged with the central trigger engagement groove 411b.

  On the other hand, when the handle 401 is rotated 180 ° from the locked position and placed at the inward position, as shown in FIG. 17, the slide block 410, the upper linkage member 403, and the lower linkage member 402 are moved downward with respect to the door-end rod 25. Slide. At this time, the upper link mechanism 240 is unlocked when the lock link 243 slides to the door end side, and the link lock pin 241c of the main link 241 deviates from the pin receiving groove 246a of the pin holder 246. The main link 241 can turn with respect to 242. In the locking device 300, the lower end portion of the locking rod 310 is inserted into the rod insertion hole 331 of the lower block member 330 in a state where the lock pin 311 is maintained at a position not facing the lock receiver 321. Therefore, in this state, when the shoji 20 is pulled indoors through the handle 401, the upper collar 22 can be separated from the upper frame 11 as shown in FIG. The shoji 20 can be opened so as to be tilted indoors about the axial center along the left and right direction connecting the spherical portion 110b and the lower end portion of the locking rod 310 inserted into the rod insertion hole 331 of the lower block member 330. It becomes (shoulder of shoji 20). When the shoji 20 is opened so as to be tilted to the indoor side, the engagement piece 444 is separated from the finding surface of the door frame 14, so that the trigger member 440 is pressed by the pressing force of the trigger spring 446 in the intermediate operating device 400. It moves to the outer side and the engagement protrusion 443 is maintained in the state engaged with the uppermost trigger engagement groove 411c.

  As described above, in the intermediate operating device 400 applied to this joinery, when the shoji 20 is inwardly opened or inward, the engagement protrusion 443 of the trigger member 440 is one of the trigger engagement grooves 411b and 411c. Engage with. Therefore, since the movement of the slide block 410 with respect to the apparatus main body 420 is restricted, the handle 401 cannot be operated. As a result, when the shoji 20 is in an open state or inward, the lock / unlock state of the upper link mechanism 240 provided between the frame 10 and the shoji 20 and the locking state of the locking device 300 are inadvertent. There is no switching. That is, the shoji 20 in which the handle 401 is opened at the inward opening position or the shoji 20 in which the handle 401 is opened in the inward position can be reliably closed as it is.

  And since the trigger member 440 is shape | molded with the metal, there is no possibility that a problem may arise in terms of durability even when the use of the joinery is performed for a long time. Furthermore, a buffer material 445 is attached to the engagement piece portion 444 at a portion that comes into contact with the finding surface of the door frame 14. Therefore, even when the engagement piece portion 444 comes into contact with the finding surface of the frame body 10 as the shoji 20 is opened and closed, the impact is alleviated, and there is no possibility that a hitting sound or a dent is generated. Furthermore, the finding surface of the door frame 14 with which the engagement piece portion 444 abuts is a portion where the tight material 15 provided on the shoji 20 is pressed when the shoji 20 is closed. Therefore, since the end portion 445a of the cushioning material 445 is disposed to face the tight material 15, the end portion 445a is pressed by the tight material 15 every time the shoji 20 is opened and closed, and the end portion 445a. There is no risk of incurring a situation where it gets drowned and peeled off. In addition, since a thin film of 0.2 mm or less is applied as the buffer material 445, the occupation rate of the buffer material 445 is reduced in a limited space between the frame 10 and the shoji 20, and as a result The plate thickness of the engaging piece portion 444 can be secured, which is further advantageous in terms of durability.

  In the above-described embodiment, the joinery in which the shoji 20 is locked by operating the handle 401 is illustrated, but the locking means is not necessarily included in the opening / closing control mechanism. May be provided separately and independently.

  Further, in the above-described embodiment, the buffer material 445 is wound around the engagement piece portion 444 that is a contact portion by one and a half turns. The buffer material 445 can be securely attached even when the adhesiveness to the combined piece portion 444 is not good. However, it is sufficient that the cushioning material 445 is provided only on the surface that contacts the frame body 10 at least in the engagement piece portion 444. In addition, although what shape | molded with the PET film is illustrated as the buffer material 445, of course, you may shape | mold with other resin. Further, it is not always necessary to apply the thin-film buffer material 445 of 0.2 mm or less, and the size of the buffer material may be arbitrarily selected.
