Description

  The present invention relates to a lock device and a joinery, and in particular, a joinery that moves in the out-of-plane direction of the opening frame when opening a shoji, such as an open window, a sliding window, or a fall window, and a lock suitable for this joinery. It relates to the device.

  A lock device provided with a cam latch and a receiving member engaged therewith in a fitting that is moved in the out-of-plane direction of the opening frame when opening the shoji, such as a case window, a sliding window, or a fall window. Is often used. In this lock device, for example, a cam latch is rotatably disposed on a face that faces the indoor side of the shovel, and a receiving member is disposed on the vertical frame of the opening frame. The cam latch is integrally provided with a handle for rotational operation.

  When the cam latch is rotated in a state where the shoji is closed with respect to the opening frame and the latch locking surface of the cam latch moves to the engagement position opposite to the receiving locking surface of the receiving member, the latch locking surface of the cam latch and the receiving member The movement of the shoji is prevented by the contact of the receiving and locking surfaces with each other, and the shoji can be kept closed. When the cam latch is rotated and the latch locking surface is disposed at the retracted position retracted from the receiving locking surface of the receiving member, the shoji can be opened with respect to the opening frame (see, for example, Patent Document 1).

  This type of locking device has a relatively simple structure, and since both the cam latch and the receiving member are attached to the finding surface of the joinery, the attaching operation is easy. However, when the shoji is closed by grasping the handle, the cam latch easily rotates from the retracted position to the engaged position. When the shoji is closed while the cam latch is in the engaged position, the cam latch and the receiving member or the opening frame collide with each other, which may cause damage to both.

  On the other hand, as another locking device used for the joinery described above, there is also provided one provided with an engagement pin and a hook member engaged with the engagement pin. In this locking device, for example, a meshing pin is disposed on a prospective surface serving as a door of a shoji, and a hook member is rotatably disposed on a prospective surface facing the meshing pin in the vertical frame of the opening frame. The hook member has a notch for receiving the engagement pin. The hook member is provided with a hook urging means and a lock member. The hook urging means always urges the hook member with respect to the opening frame so that the notch of the hook member is in an open posture that opens toward the outdoor side. The lock member is engaged with the hook member when the notch of the hook member is opened along the vertical frame, and maintains the engagement posture of the lock member against the urging force of the hook urging means. It is. The lock member is provided with a release lever for operating from the outside of the opening frame.

  When the shoji is opened to the outdoor side with respect to the opening frame, the hook member is brought into an open posture by the hook urging means. When the shoji is moved in the closing direction with respect to the opening frame from this state, the meshing pin provided on the shoji enters the notch of the hook member, and the hook member rotates to become the meshing posture when the shoji is closed. When the hook member is in the meshing posture, the lock member is engaged with the hook member, and the meshing posture of the hook member is maintained. In this state, since the meshing pin cannot deviate from the notch of the hook member, the movement of the shoji is prevented and the closed state is maintained. By operating the release lever to move the lock member and releasing the engagement with the hook member, the hook member can be moved to the open posture. Therefore, the shoji can be opened by pushing the shoji against the opening frame (see, for example, Patent Document 2).

  According to this type of locking device, the engagement pin is in contact with the movable direction of the hook member, and the posture of the hook member is not changed with the opening / closing operation of the shoji. There is no risk of damage to both sides.

As shown in FIGS. 2-1 to 3-2, the release lever 44 protruding from the base member 41 has the right vertical frame 14 and the right vertical rod 24 even when the shoji 20 is closed with respect to the opening frame 10. The connecting portion 44e is disposed along the finding surface facing the indoor side of the right vertical shaft 24 so that the linkage portion 44e can be led out to the indoor side beyond the fin portion 14a.

  An operation grip 50 is attached to the right vertical arm 24 of the shoji 20 to which the lock unit 40 is attached at a position where the linkage part 44e of the release lever 44 is covered on the finding surface. The operation grip 50 is configured to include a grip body 51 and a lock operation section 52, and is fixed to the finding surface of the right vertical basket 24 via the proximal end portion of the grip body 51. The grip body 51 extends along a direction perpendicular to the longitudinal direction of the right vertical rod 24 and away from the right vertical frame 14. The grip body 51 has a storage chamber 51a at the base end. The storage chamber 51a is a space that opens to the outer surface of the grip body 51 through the linkage hole 51b and that has a portion facing the right vertical shaft 24, and incorporates a lever linkage 53 therein. The lever linkage 53 is a top-like member having a linkage groove 53 a at a portion facing the finding surface of the right vertical rod 24, and is arranged so as to be movable along the longitudinal direction of the grip body 51. The linkage groove 53a of the lever linkage 53 is a groove-like opening having a width larger than the plate thickness of the release lever 44, and accommodates the linkage portion 44e of the release lever 44 therein. As is apparent from the drawing, the lever linkage 53 is constantly urged toward the base end side inside the accommodating chamber 51 a by the urging force of the grip urging spring 54 built in the grip body 51. The lock operation part 52 is arranged on the outer surface located on the indoor side at the base end part of the operation grip 50 so as to be movable along the longitudinal direction of the operation grip 50. The lock operation unit 52 is provided with an operation output piece 52a. The operation output piece 52 a enters the inside of the operation grip 50 through the linkage hole 51 b formed in the operation grip 50, and the tip thereof is biased by the grip biasing spring 54 through the lever linkage 53. is there.

  In this operation grip 50, the lever linkage 53 is always urged toward the base end side of the operation grip 50 by a grip urging spring 54. Therefore, when no operating force is applied to the lock operating portion 52, the release lever 44 of the lock unit 40 linked via the lever linkage 53 is provided with the lever 44c as shown in FIG. The urging force of the urging spring 442 is brought into contact with the main plate portion 41a of the base member 41.

The slide portion 44d of the release lever 44 is moved along the longitudinal direction, and the action portion 44c moves in a direction away from the main plate portion 41a. When the operation force of the lock operation portion 52 is removed, the lock operation portion 52 and the lever linkage 53 are moved to the proximal end side of the grip body 51 by the urging force of the grip urging spring 54 as shown in FIG. Then, the normal state is restored, and further, the urging force of the lever urging spring 442 causes the action portion 44c of the release lever 44 to return to the normal position again in contact with the main plate portion 41a.

  Hereinafter, the operation of the lock device when opening and closing the shoji 20 with respect to the opening frame 10 will be described, and the characteristic part of the present application will be described in detail. In addition, as shown to FIGS. 2-3, let the state in which the shoji 20 is open with respect to the opening frame 10 be an initial state of joinery. At this time, in the lock unit 40 of the locking device, as shown in FIG. 7C, the lock member 43 extends along the axial direction of the lock shaft 431, that is, along the rotational axis of the hook shaft 421. It moves in a direction away from the main plate portion 41a of 41, and its outer peripheral surface is at a position shifted from the outer peripheral surface of the hook member 42 (non-engagement position). For this reason, as indicated by a two-dot chain line in FIGS. 4A and 4B, the hook member 42 is brought into a non-engagement posture by the biasing force of the hook biasing spring 423, and the opening of the meshing groove 42e is formed in the base member 41. It is in a state opened to the entry groove 41d. As shown in FIG. 7C, the lock member 43 in the non-engagement position is urged in a direction approaching the hook member 42 by the urging force of the lock urging spring 432, and the hook member 42 is interposed via the end surface. It is in a state of being pressed against. The release lever 44 is separated from the lock member 43 by the urging force of the lever urging spring 442 and is in a normal position where it abuts against the main plate portion 41a of the base member 41. The operation unit 52 is in a state of being located on the proximal end side of the grip body 51.

  When the operation grip 50 is gripped from this state and the right vertical rod 24 of the shoji 20 is pulled to the indoor side, the engagement pin 30 provided on the right vertical frame 14 enters the entry groove 41d of the base member 41 and the hook member 42 eventually. By contacting the first rotation restricting portion 42a, the hook member 42 is rotated in a direction to be a meshing posture. When the hook member 42 is rotated to the engagement posture, the opening of the entry groove 41d is closed by the hook portion 42c of the hook member 42 as shown by the solid line in FIGS. 4A and 4B. It will be in the state which cannot deviate from 30. In addition, when the hook member 42 is in the meshing position, the lock member 43 moves in the direction approaching the main plate portion 41a of the base member 41 by the biasing force of the lock biasing spring 432 as shown in FIG. Then, as shown by a solid line in FIGS. 4A and 4B, the contact is made with the hook side contact surface 42d of the hook member 42 via the lock side contact surface 43b (engagement position). As a result, the hook member 42 is maintained in the meshing posture against the urging force of the hook urging spring 423, and the shoji 20 is maintained in the closed state with respect to the opening frame 10.

  On the other hand, when the shoji 20 is opened with respect to the opening frame 10, the lock operation unit 52 may be moved toward the distal end side with respect to the grip body 51 of the operation grip 50 as shown in FIG. That is, when the lock operation portion 52 of the operation grip 50 is moved to the distal end portion side of the grip body 51, as shown in FIG. 7-2, the release lever 44 via the lever linkage body 53, the linkage portion 44e, and the slide portion 44d. The acting portion 44c is separated from the main plate portion 41a together with the lock member 43 against the urging force of the lever urging spring 442 and further the urging force of the lock urging spring 432, and the outer peripheral surface of the lock member 43 is the hook member 42. It moves to a position (non-engagement position) shifted from the outer peripheral surface. As a result, as shown by the two-dot chain line in FIGS. 4-2 and 6, the hook member 42 rotates to the non-engagement posture, and the right vertical arm 24 of the shoji 20 is pushed to the outdoor side via the operation grip 50. If it comes out, the engagement pin 30 can deviate from the entry groove 41 d of the base member 41, so that the shoji 20 can be opened with respect to the opening frame 10. When the operating force is removed from the lock operating portion 52 after the shoji 20 is opened, the lock operating portion 52 and the lever linkage 53 are moved to the grip body 51 by the biasing force of the grip biasing spring 54 as shown in FIG. 7b, and the urging force of the lever urging spring 442 returns the operating portion 44c of the release lever 44 to the normal position again in contact with the main plate portion 41a, as shown in FIG. 7-3. .

  Here, when opening the shoji 20, the slide portion 44 d of the release lever 44 is moved along the longitudinal direction via the lock operation portion 52, so that the slide portion 44 d is moved with respect to the right vertical shaft 24 of the shoji 20. It will be in sliding contact. However, in this joinery, since the lock member 43 moves relative to the hook member 42 along the rotation axis of the hook member 42, the hook member 42 switches from the engaged position to the non-engaged position. 1 and 3-2, the hook member 42 is switched by sliding the slide portion 44d of the release lever 44 derived from the gap between the right vertical frame 14 and the right vertical rod 24 along the longitudinal direction thereof. Can be operated. For this reason, the sliding contact mark is also released even when the right vertical hook 24 and the release lever 44 are in sliding contact with each other as the release lever 44 is operated, and a sliding contact mark is generated on the finding surface of the right vertical hook 24. It occurs only at the position covered by the lever 44 and does not appear on the surface of the right downspout 24.

  Further, with respect to the inner gasket 15 provided between the right vertical frame 14 and the right vertical rod 24, the position of the release lever 44 does not change in the longitudinal direction. There is no fear of greatly affecting Further, since the action portion 44c of the release lever 44 has already returned to the normal position in contact with the main plate portion 41a of the base member 41 when the shoji 20 is open, when the shoji 20 is closed, the release lever 44 and the inner There is no sliding contact with the gasket 15.

  As a result, according to the above-mentioned joinery, it is possible to ensure good operability while ensuring desired watertightness and airtightness without impairing the appearance quality.

(Embodiment 2)
FIGS. 8-1 to 9 show a locking device according to the second embodiment of the present invention. The lock device illustrated here has a lock unit arranged on the right vertical saddle of the shoji in the same vertical sliding window as the fitting shown in FIG. 1 in the first embodiment, and a corresponding engagement pin is provided in the right vertical frame. Only the detailed configuration of the lock unit is different from the first embodiment. That is, as shown in FIGS. 8A to 9, in the lock unit 140 of the second embodiment, there is no release lever as an independent part, and the release lever 144 is integrally provided on the lock member 43. The release lever 144 has a base end portion 144a connected to an edge portion of the lock member 43 on the side where the entry groove 41d opens, bends at a substantially right angle, and the slide portion 144d extends in the same direction as the protruding direction of the lock shaft 431. Furthermore, the distal end portion of the slide portion 144d bends at a substantially right angle and extends in a direction away from the main plate portion 41a of the base member 41 to constitute a linkage portion 144e. As in the first embodiment, the linkage portion 144e of the release lever 144 is linked to a lever linkage body of an operation grip (not shown), and the release lever 144 is operated by the operation of the lock operation portion. In addition, in the lock unit 140, about the structure similar to Embodiment 1, the same code | symbol is attached | subjected and each detailed description is abbreviate | omitted.

  In the lock unit 140 of the lock device, when the shoji is open with respect to the opening frame, as shown in FIG. 8B, the lock member 43 is arranged along the axial direction of the lock shaft 431, that is, the hook shaft 421. Is moved in a direction away from the main plate portion 41a of the base member 41, and its outer peripheral surface is at a position shifted from the outer peripheral surface of the hook member 42 (non-engagement position). For this reason, the hook member 42 is in the non-engagement posture due to the biasing force of the hook biasing spring 423, and the opening of the meshing groove 42 e is open to the entry groove 41 d of the base member 41. The lock member 43 in the non-engagement position is urged in the direction approaching the hook member 42 by the urging force of the lock urging spring 432 and is in a state of being pressed against the hook member 42 via the end surface. Accordingly, the release lever 144 extending from the lock member 43 is in a state in which the slide portion 144d is pulled out, and a lock operation portion of an operation grip (not shown) is located on the distal end side of the grip body.

  When the operating grip is gripped from this state and the right vertical saddle of the shoji is pulled to the indoor side, the engagement pin provided in the right vertical frame eventually enters the entry groove 41d of the base member 41, and the first rotation restriction of the hook member 42 is achieved. By abutting on the portion 42a, the hook member 42 is rotated in the direction of the meshing posture. When the hook member 42 rotates to the engagement posture, as shown in FIG. 8A, the opening of the entry groove 41d is closed by the hook portion 42c of the hook member 42, and therefore the engagement pin cannot be deviated from the entry groove 41d. It becomes a state. In addition, when the hook member 42 is brought into the meshing posture, the urging force of the lock urging spring 432 moves the lock member 43 in the direction approaching the main plate portion 41a of the base member 41, so that the lock-side contact surface 43b is moved. Via the hook-side contact surface 42d of the hook member 42 (engagement position). As a result, the hook member 42 is maintained in the meshing posture against the urging force of the hook urging spring 423, and the shoji is maintained in a closed state with respect to the opening frame. Although not clearly shown in the figure, when the lock member 43 comes into contact with the main plate portion 41a of the base member 41, the release lever 144 slides and the lock operation portion moves to the proximal end side of the grip body. Become.

  On the other hand, when the lock operation portion of the operation grip is moved to the tip end side of the grip body, the release lever 144 is moved via the linkage portion 144e and the slide portion 144d as shown in FIG. The lock member 43 is separated from the main plate portion 41 a against the urging force of 432, and the outer peripheral surface thereof moves to a position (non-engagement position) shifted from the outer peripheral surface of the hook member 42. As a result, the hook member 42 is rotated to be in the non-engagement posture, and the engagement pin can deviate from the entry groove 41d of the base member 41 by pushing the right vertical shaft of the shoji to the outdoor side via the operation grip. The shoji can be opened against.

  Here, also in the second embodiment, when the shoji is opened, the slide portion 144d of the release lever 144 moves along the longitudinal direction via the lock operation portion. 144d comes into sliding contact. However, since the lock member 43 moves relative to the hook member 42 along the rotation axis of the hook member 42, the hook member 42 is switched from the engaged position to the non-engaged position. The hook member 42 can be switched by sliding the slide portion 144d of the release lever 144 led out from the clearance along the longitudinal direction thereof. Therefore, when the release lever 144 is operated, the right downside and the release lever 144 are in sliding contact with each other, and even if a sliding contact mark is generated on the finding surface of the right downside, the sliding contact mark is not released. It will occur only at the position covered by and will not appear on the surface of the right downspout.

  In addition, even when an inner gasket is provided between the right vertical frame and the right vertical rod, the position of the release lever 144 does not change in the longitudinal direction, which greatly increases the sealing function of the inner gasket. There is no fear of influence.

  As a result, also in the second embodiment, it is possible to ensure good operability while ensuring the desired water tightness and air tightness without impairing the appearance quality.

(Embodiment 3)
FIGS. 10-1 to 11 show a locking device according to Embodiment 3 of the present invention. The lock device illustrated here has a lock unit arranged on the right vertical saddle of the shoji in the same vertical sliding window as the fitting shown in FIG. 1 in the first embodiment, and a corresponding engagement pin is provided in the right vertical frame. Only the detailed configuration of the lock unit is different from the first embodiment. That is, as shown in FIGS. 10A to 11, in the lock unit 240 of the third embodiment, there is no lock member 243 as an independent part, and the lock member 243 is integrally provided on the release lever 244. .

  The release lever 244 is a thin plate member rich in elasticity, and a base end portion 244a is provided at a position above the hook shaft 421 in the main plate portion 41a of the base member 41 by a lever fixing pin 2441 orthogonal to the main plate portion 41a. It is fixed through. The release lever 244 has an action portion (engagement biasing means) 244c extending from the base end portion 244a substantially horizontally, and further bent at a substantially right angle so that the slide portion 244d is in the same direction as the protruding direction of the hook shaft 421. Extend. Further, the release lever 244 forms a linkage portion 244e by bending the tip end portion of the slide portion 244d at a substantially right angle and extending in a direction away from the main plate portion 41a of the base member 41. The action portion 244c of the release lever 244 is formed to have a width that does not contact the hook member 42 even when the hook member 42 is in the non-engagement posture. As in the first embodiment, the linkage portion 244e of the release lever 244 is linked to a lever linkage body of an operation grip (not shown), and the release lever 244 is operated by the operation of the lock operation portion. Note that reference numeral 245 in FIG. 11 is a spacer interposed between the base end portion 244 a of the release lever 244 and the main plate portion 41 a of the base member 41.

  The lock member 243 has a flat plate shape having substantially the same thickness as that of the hook member 42, and has an outer shape protruding downward from the action portion 244c. The lock member 243 is integrally connected to the action portion 244c. The lock member 243 is formed by elastically deforming the action portion 244c of the release lever 244 with the lever fixing pin 2441 as a fulcrum, so that the outer peripheral surface thereof faces the outer peripheral surface of the hook member 42, and the hook member 42 It is possible to switch to a state shifted from the outer peripheral surface. When the outer peripheral surface of the lock member 243 is deviated from the outer peripheral surface of the hook member 42, the lock member 243 is biased in the direction approaching the main plate portion 41 a of the base member 41 by the elastic restoring force of the action portion 244 c that is elastically deformed. .

  The lock member 243 is provided with a lock-side contact surface 243b at the end protruding downward. The lock-side contact surface 243b contacts the hook-side contact surface 42d of the hook member 42 when the outer peripheral surface of the lock member 243 is opposed to the outer peripheral surface of the hook member 42 in a state where the hook member 42 is in the meshing position. The hook member 42 is kept in the meshing posture against the urging force of the hook urging spring 423 (engagement position).

  In addition, in the lock unit 240, about the structure similar to Embodiment 1, the same code | symbol is attached | subjected and each detailed description is abbreviate | omitted.

  In the lock unit 240 of this locking device, when the shoji is open with respect to the opening frame, the lock member 243 moves in a direction away from the main plate portion 41a of the base member 41, as shown in FIG. In other words, the hook shaft 421 moves in the direction along the rotation axis, and the outer peripheral surface thereof is at a position shifted from the outer peripheral surface of the hook member 42 (non-engagement position). For this reason, the hook member 42 is in the non-engagement posture due to the biasing force of the hook biasing spring 423, and the opening of the meshing groove 42 e is open to the entry groove 41 d of the base member 41. The lock member 243 in the non-engagement position is urged in the direction approaching the hook member 42 by the elastic restoring force of the action portion 244c in the release lever 244, and is brought into pressure contact with the hook member 42 through the end surface. is there. Accordingly, the release lever 244 extending from the lock member 243 is in a state in which the slide portion 244d is pulled out, and a lock operation portion of an operation grip (not shown) is located on the distal end side of the grip body.

  When the operating grip is gripped from this state and the right vertical saddle of the shoji is pulled to the indoor side, the engagement pin provided in the right vertical frame eventually enters the entry groove 41d of the base member 41, and the first rotation restriction of the hook member 42 is achieved. By abutting on the portion 42a, the hook member 42 is rotated in the direction of the meshing posture. When the hook member 42 rotates to the engagement posture, as shown in FIG. 10A, the opening of the entry groove 41d is closed by the hook portion 42c of the hook member 42, and thus the engagement pin cannot be deviated from the entry groove 41d. It becomes a state. Moreover, when the hook member 42 is brought into the meshing posture, the lock member 243 moves in the direction approaching the main plate portion 41a of the base member 41 by the elastic restoring force of the action portion 244c in the release lever 244, and the lock side contact is made. It abuts on the hook side abutting surface 42d of the hook member 42 via the surface 243b (engagement position). As a result, the hook member 42 is maintained in the meshing posture against the urging force of the hook urging spring 423, and the shoji is maintained in a closed state with respect to the opening frame. Although not shown in the figure, the release lever 244 slides when the lock member 243 comes into contact with the main plate portion 41a of the base member 41, and the lock operation portion moves to the proximal end side of the grip body. Become.

  On the other hand, when the lock operation portion of the operation grip is moved to the tip end side of the grip body, the action portion 244c of the release lever 244 is moved via the linkage portion 244e and the slide portion 244d as shown in FIG. The action portion 244c is elastically deformed, the lock member 243 is separated from the main plate portion 41a, and the outer peripheral surface thereof moves to a position shifted from the outer peripheral surface of the hook member 42 (non-engagement position). As a result, the hook member 42 is rotated to be in the non-engagement posture, and the engagement pin can deviate from the entry groove 41d of the base member 41 by pushing the right vertical shaft of the shoji to the outdoor side via the operation grip. The shoji can be opened against.

  Here, also in the third embodiment, when the shoji is opened, the slide portion 244d of the release lever 244 is moved in the longitudinal direction via the lock operation portion. Will come into sliding contact. However, since the lock member 243 moves relative to the hook member 42 in the direction along the rotation axis of the hook member 42, the hook member 42 switches from the engaged position to the non-engaged position. The hook member 42 can be switched by sliding the slide portion 244d of the release lever 244 derived from the gap with the vertical hook along the longitudinal direction thereof. For this reason, when the release lever 244 is operated, the right downspout and the release lever 244 are brought into sliding contact with each other, and even if a sliding contact mark is generated on the finding surface of the right downside, the sliding contact trace is not released. It will occur only at the position covered by and will not appear on the surface of the right downspout.

  In addition, even when an inner gasket is provided between the right vertical frame and the right vertical rod, the position of the release lever 244 does not change in the longitudinal direction, which greatly increases the sealing function of the inner gasket. There is no fear of influence.

  As a result, also in the third embodiment, it is possible to ensure good operability while ensuring the desired water tightness and air tightness without impairing the appearance quality. In addition, since the action portion 244c of the release lever 244 also functions as an engagement urging means that urges the lock member 243 toward the engagement position, it is not necessary to separately provide an engagement urging means. By reducing the number of points, it becomes possible to facilitate the manufacturing work of the lock device and to reduce the manufacturing cost.

  In addition, in Embodiment 1- Embodiment 3 mentioned above, all have illustrated the vertical sliding window as a fitting, However, This invention is not limited to this, It is a shoji by moving to the out-of-plane direction of an opening frame If the joinery is configured to open the door, it can be applied to a side sliding window, an open window, or a fall window. When applied to a vertical sliding window, the left and right opening directions may be opposite to those in the first embodiment.

  In the above-described first to third embodiments, only the lock member can be moved in the direction along the rotation axis of the hook member with respect to the hook member with the base member as a reference. You may comprise so that only a hook member can move to the direction along the rotating shaft center of a hook member on the basis of a base member.

  Furthermore, in Embodiment 1 and Embodiment 2 described above, the lock member is configured to be movable in a direction parallel to the rotation axis of the hook member. However, the lock member extends along the rotation axis of the hook member. If it is a direction, it is not always necessary to move it in parallel.
