Description

  The present invention relates to a latch device and a fitting, and more specifically, a latch that locks a face member supported in a window frame so as to be openable and closable with the window frame, and allows the face member to be opened and closed by releasing the lock. The present invention relates to a fitting including a device and a latch device.

As a fitting (sash window) provided in an opening of an outer wall of a house or the like, a raising / lowering window having a shoji that can be opened and closed upside down and tilted inward is known (see, for example, Patent Document 1). Is provided with a latch device that locks the vertical frame to support the shoji so that it cannot move in the expected direction and is slidable up and down, and allows the shoji to be tilted and operated by releasing the latch.
A latch device described in Patent Document 1 is provided with a latch (locking member) supported by a sliding member fixed to a shoji so as to protrude and retract toward a vertical frame, and a knob coupled to the latch. And a spring provided inside the sliding member to project the latch, and by operating the knob to immerse the latch on the upper side of the shoji against the urging force of the spring, Can be released. An inclined surface is formed on the outer side surface of the front end portion of the latch, and when the shoji that is opened inward is closed, the inclined surface abuts against the indoor side edge or the frame of the vertical frame so that the spring biasing force is applied. In contrast, the latch is immersed, and when the shoji is pushed to a predetermined expected position of the window frame, the latch protrudes and the vertical frame can be locked.

On the other hand, as a device similar to the above-described latch device, a fixing device for fixing an openable / closable door (face material) provided in furniture or the like in a closed position has been proposed (for example, see Patent Document 2).

However, in the conventional latch device as described in Patent Document 1, when closing the fallen shoji, the inclined surface is rubbed against the vertical frame so that the latch is immersed. There is a problem that the surface and the frame may be flawed, which is not preferable in view of the beauty of the joinery.
Further, in the conventional fixing device as described in Patent Document 2, the tip of the fixing member is shifted from the insertion hole by the spring eccentric with respect to the protruding and retracting direction of the fixing member and locked to the housing. Therefore, the urging force in the direction intersecting with the direction of protrusion (inward of the furniture) always acts on the fixing member, and a frictional force is generated between the fixing member and the insertion hole of the housing. There is a problem that each member is worn and the durability is inferior, or the fixing member is caught during the projecting movement and the stability of the operation is lowered. Furthermore, when the stopper is brought into contact with the contact piece of the receiver and the tip of the fixing member is moved to the insertion hole side, the fixing member may be caught, and the fixing member does not protrude from the housing. There is also a possibility of becoming impossible to engage with. In addition, even when engaged with the receiver, the fixing member is biased inward of the furniture, so that a gap is generated between the front end of the fixing member and the engaging hole of the receiver in the door opening direction. There is also a problem that the fixed door rattles against the furniture body.

  An object of the present invention is to provide a latch device and a fitting capable of preventing flaws and maintaining aesthetic appearance, ensuring durability and operational stability, and preventing shakiness of a face material.

  The latch device of the present invention is a latch device that locks the face material supported by the frame body so as to be openable and closable to the frame body, and enables the opening and closing operation of the face material by releasing the lock. The latch device is capable of projecting and retracting between a latch main body fixed to the face material, and a locking position supported by the latch main body to lock the frame body and a non-locking position in which the locking is released. A locking member, a first urging means for urging the locking member toward the locking position with respect to the latch body, and the latch body supported by the latch body so as to be able to protrude from the face material. A restriction member that engages with the locking member and restricts movement of the locking member, and a second urging means that urges the restriction member in the protruding direction are configured. A contact portion that protrudes from the face material and can contact the frame body, and an engagement that can engage with the locking member When the face member is opened by moving the locking member to the non-locking position, the abutting portion is moved to the surface by the urging force of the second urging means. And when the engaging portion engages with the locking member to restrict the movement to the locking position and the face member is closed, the contact portion contacts the frame body. The frame member is engaged with the locking member moved into the locking position by the biasing force of the first biasing means. It is characterized by locking.

  Here, the openable and closable face materials are shoji and doors, which are slidingly supported by a frame (window frame, opening frame, door frame, etc.), a single-drawing type, or a raising / lowering type. Alternatively, an open type or a protruding type, a vertical (or horizontal) protruding type, or an internal (or external) tilting type supported rotatably on the frame may be used.

According to the present invention described above, when the face material is opened, the engaging member that has been moved to the non-locking position is engaged by the engaging portion of the restricting member to restrict the movement to the locking position. By keeping the locking member in the non-locking position, the locking member does not rub against the frame or the frame when closing the face material, and it is possible to prevent the interior surfaces from being scratched. Can maintain the beauty of joinery. When the face material is closed, the contact portion comes into contact with the frame and the engagement portion is detached from the locking member, and the locking member is moved to the locking position by the biasing force of the first biasing means. The frame can be automatically locked by the locking member without manual operation.
Further, by providing a locking member that is supported by the latch body so as to be able to project and retract, and a regulating member that engages with the locking member to restrict movement, the locking member at the non-locking position is attached. It is no longer necessary to shift it in the direction crossing the protrusion / disengagement direction and lock it to the latch body, etc., and the locking member may be caught during the protrusion / retraction movement, or a large frictional force may be generated between it and the latch body. Can be prevented, and durability and operational stability can be secured. Further, since the latch member only has to be guided by the latch body so as to be movable only in the projecting and retracting direction, it is not necessary to provide an extra clearance at the latching portion with the frame body. Locking accuracy can be increased and rattling of the locked face material can be prevented.

In this case, in the latch device according to the present invention, the restricting member of the latch device is rotatably supported by the latch body along the locking member, and the abutting portion is disposed on one side across the rotating shaft. The engaging portion is formed on the other side, and the engaging member is received at a position corresponding to the engaging portion of the restricting member in a state where the engaging member is immersed to the non-locking position. It is preferable that an engaged portion for rotating the regulating member is formed.
In the latch device of the present invention, the regulating member of the latch device is slidably supported by the latch body along the direction intersecting the protruding and retracting direction of the locking member, and the locking member can be inserted therethrough. The contact portion is formed at one end portion of the plate material, and the engagement portion is formed at an end edge of the insertion hole opposite to the contact portion. In the stopping member, an engaged portion that receives the engaging portion and slides the restricting member is formed at a position corresponding to the engaging portion of the restricting member in a state of being immersed to the non-locking position. Good.

According to such a configuration, either the configuration in which the regulating member is pivotally supported or the regulating member is slidably supported can be appropriately selected according to the mounting condition of the latch device.
And when adopting a configuration that supports the regulating member so as to be rotatable, the contact portion and the engaging portion are formed apart from each other on one end side and the other end side with the rotation shaft interposed therebetween. If a contact portion is provided on the distal end side of the locking member in the protruding direction and an engagement portion is provided on the proximal end side of the locking member, it is close to the locking position with the frame on the distal end side of the locking member. A contact part can be located in a part. In addition, if the engaged portion of the locking member is formed at a position entering the inside of the latch body corresponding to the engaging portion of the restricting member, the engaging portion and the engaged portion are positioned at a position where it is difficult to receive external impact. Since the joint portion can be engaged, it is possible to prevent the engagement from being unintentionally released and to improve the operation stability.
Further, in the case of adopting a configuration in which the restricting member is slidably supported, since the sliding direction intersects the protruding and retracting direction of the locking member, the member of the restricting member along the protruding and retracting direction of the locking member The dimension (width dimension) can be reduced, and the installation position of the restricting member (installation position along the protruding and retracting direction of the locking member) can be appropriately set according to the form of the frame body with which the contact part comes into contact. it can. Moreover, the crossing angle of the sliding direction of the regulating member with respect to the protruding and retracting direction of the locking member can be arbitrarily set, and by appropriately setting the sliding direction of the regulating member according to the form of the frame and the opening / closing direction of the face material The contact portion of the restricting member and the frame can be brought into contact with each other at an appropriate angle.

  On the other hand, a joinery of the present invention includes a window frame having an upper frame, a lower frame, and left and right vertical frames, and at least one shoji that is guided by the vertical frame and supported so as to be openable and slidable vertically. On both the left and right ends of the upper edge of the shoji, there is a fitting provided with a latch device that locks the vertical frame and is slidably guided to the vertical frame, and that allows the shoji to be operated inward by releasing the lock. The latch device projects between a latch main body fixed to the shoji, and a locking position supported by the latch main body for locking the vertical frame and a non-locking position for releasing the locking. A locking member that can be moved in a submerged manner, a first urging means that urges the locking member toward the locking position with respect to the latch body, and the latch that can protrude outward from the outdoor surface of the shoji. The locking portion is supported by the main body and engages with the locking member at the protruding position. And a second urging means for urging the regulating member toward the outdoor side, and the regulating member protrudes further to the outdoor side than the outdoor surface of the shoji. And the engagement part engageable with the locking member, and the locking member is operated to move to the non-locking position. Is moved inward, the abutting portion protrudes to the outdoor side by the urging force of the second urging means, and the engaging portion engages with the locking member and moves to the locking position. When the shoji is returned to the sliding position in the window frame, the abutting portion comes into contact with the vertical frame and enters the indoor side, and the engaging portion is separated from the locking member. The vertical frame is locked by the locking member that has been moved and moved to the locking position by the biasing force of the first biasing means.

  According to the present invention described above, in the raising and lowering window in which the shoji can be opened and closed vertically and can be turned inward, the locking member of the latch device does not rub against the vertical frame or the frame, so that flaws can be prevented and the appearance of the fitting is maintained. can do. Furthermore, as in the case of the latch device described above, it is possible to prevent the locking member from being caught while projecting and retracting, and to generate a large frictional force with the latch body, ensuring durability and operational stability. In addition, it is possible to prevent the shoji that is locked to the vertical frame from rattling.

  In this case, the joinery of the present invention includes an outdoor upper shoji and an indoor lower shoji, and the lower shoji is configured to be vertically slidable and inwardly movable, and can be operated inwardly. The latch device is provided at both ends, and the upper and lower shojis are respectively configured to have an upper arm, a lower arm, and left and right vertical rods, and panels fitted inside these, The frame is provided with an upper protrusion and a lower protrusion that protrude inward in the direction of finding, respectively, and the upper protrusion is connected to the interior side surface of the vertical shovel of the upper shoji and an airtight material. The lower projecting portion is brought into contact with an outer side surface of the vertical shovel of the lower shoji through an airtight material, and the regulating member in the latch device is in contact with the inner side surface of the upper projecting portion. The part abuts and the engaging part It is preferably configured to disengage from the locking member.

  According to such a configuration, the contact portion of the regulating member in the latch device provided in the lower shoji that can be turned inward is the upper projecting portion of the vertical frame that is in contact with the vertical saddle of the upper shoji through the airtight material, that is, the upper and lower Since it is configured to abut against the upper projecting portion that extends continuously, the operation is performed so that the abutting portion is positioned at a specific height position when returning the inverted lower shoji into the window frame. Even if it is not, simply by pushing the shoji into the window frame at an appropriate height position, the abutment and the upper protrusion can be brought into contact with each other and the vertical frame can be locked to the locking member. Can be improved. And by making a contact part contact the upper projection part which constitutes an airtight line of an upper shoji, it becomes unnecessary to provide a contacted part in a vertical frame separately, and it can prevent an increase in the number of parts, and Appearance can be improved. In addition, since the contact part of the restricting member is configured to protrude to the outside of the lower shoji, it is difficult for the user to touch the contact part when tilting inward, and the contact part is pushed and locked unintentionally. An erroneous operation that causes the member to protrude can be prevented.

In the lower shoji 30, slide shoes (not shown) provided at the lower ends of the lower rod 32 and the vertical rod 33 are guided by the guide groove 132, and these slide shoes are connected to the balancer directly or via a wire or the like. Thus, the weight of the lower shoji 30 is offset, and it can be opened and closed with a small force, and the locking device 321 provided in the lower collar 32 is closed by engaging the lock receiver of the lower frame 12. Lockable in position.

  Moreover, the lower shoji 30 is rotatably supported by the slide shoe, and as shown in FIG. 3, the lower shoji 30 is configured to be pivotable (inwardly tiltable) indoors around the lower end of the lower shoji 30. ing. A latch device 40 is provided on the upper and left and right ends of the lower shoji 30. These latch devices 40 engage the guide groove 132 of the vertical frame 13 when the lower shoji 30 is normally opened and closed. The lower shoji 30 can be tilted inward by being guided by sliding. The inward operation of the lower shoji 30 will be described in detail. The lock 321 is unlocked by operating the handle 322 of the lower rod 32 from the closed position shown in FIG. 1, and the lower shoji 30 is opened slightly upward. When the lower collar 32 is detached from the lower frame 12, the lower shoji 30 can be operated inward by releasing the latch of the vertical frame 13 by the latch device 40. The lower shoji 30 is supported by an arm member (not shown) connected to the vertical frame 13 or a lock member provided on the slide shoe in the state of being tilted inward. In addition, the latch device 40 is attached to the guide groove 132 of the vertical frame 13 by rotating the upper part of the lower shoji 30 to the outdoor side and pushing it to the slide open / close position in the window frame 10 from the state of being tilted inward. The member 135 (see FIG. 5) is automatically locked, and the lower shoji 30 is supported so as to be able to open and close up and down.

  As shown in FIGS. 4 and 5, the latch device 40 includes a latch main body 41 fixed to the upper collar 31 and the vertical collar 33 of the lower shoji 30, and a latch supported by the latch main body 41 so as to be slidable and slidable. A latch bolt 42 as a member and an operation knob 43 for immersing the latch bolt 42 are configured. The latch bolt 42 protrudes from the latch body 41 as shown in FIG. 5 (A) and engages with the latch body 41 as shown in FIG. 5 (B). The latch bolt 42 is configured to project and retract between an unlocked position where the locking with the guide member 135 is released, and an engagement portion 453 of a trigger 45 which will be described later is attached to the latch bolt 42. A notch 421 is provided as an engaged portion to be engaged. Inside the latch main body 41, a coil spring 44 as a first urging means for urging the latch bolt 42 toward the locking position, and a latch bolt 42 engaged with the latch bolt 42 in the non-locking position. A trigger 45 as a restricting member for restricting the projecting movement of 42 and a leaf spring 46 as a second urging means for urging the trigger 45 are provided.

  The trigger 45 is supported by a rotation shaft 451 so as to be rotatable on the latch body 41 along the outdoor side of the latch bolt 42, and on the leading end side in the protruding direction of the latch bolt 42 on one side of the rotation shaft 451. The contact portion 452 is provided, and an engagement portion 453 provided on the base end side of the latch bolt 42 on the other side across the rotation shaft 451 is formed. And the trigger 45 is urged | biased by the leaf | plate spring 46 in the direction in which the contact part 452 protrudes from the lower shoji 30 to the outdoor side, and the lower shoji 30 is placed in the window frame 10 as shown in FIG. When in the slide open / close position, the abutting portion 452 is abutted against and pressed against the inclined surface 133 </ b> A that is the interior surface of the upper projecting portion 133 of the vertical frame 13, and resists the biasing force of the leaf spring 46. I am immersed in it.

  In addition, as shown in FIG. 5B, when the operation bolt 43 is operated to immerse the latch bolt 42 and the lower shoji 30 is operated inwardly, the latch bolt 42 inserted to the non-locking position The notch 421 moves to the position of the engaging portion 453, the trigger 45 is rotated by the urging force of the leaf spring 46, the engaging portion 453 enters the notch 421, and the abutting portion 452 protrudes to the outdoor side. It is like that. The engagement portion 453 moved to the indoor side is engaged with the notch 421, so that the protruding movement of the latch bolt 42 is restricted, and the latch bolt 42 is held in the non-locking position. .

  On the other hand, when the lower shoji 30 is pushed into the slide opening / closing position in the window frame 10, the abutting portion 452 of the trigger 45 abuts on the inclined surface 133 </ b> A of the upper protruding portion 133 and resists the urging force of the leaf spring 46. Thus, the trigger 45 is rotated so that the contact portion 452 is immersed in the latch main body 41, and the engagement between the engagement portion 453 and the notch 421 is released. When the engagement with the engaging portion 453 is released in this manner, the latch bolt 42 is protruded to the locking position by the biasing force of the coil spring 44, and the protruding latch bolt 42 locks the guide member 135 of the vertical frame 13. Will be. As a result, the latch bolt 42 is guided by the guide member 135 so that the lower shoji 30 is supported so as to be able to open and close up and down.

According to this embodiment, there are the following effects.
(1) That is, when the lower shoji 30 is tilted inward, the latch bolt 42 that has been moved to the non-locking position is engaged with the engaging portion 453 of the trigger 45 to restrict the movement to the locking position. Since the latch bolt 42 is held in the non-locking position, the tip of the latch bolt 42 does not rub against the vertical frame 13 or the frame 2 when the lower shoji 30 is pushed to the sliding open / close position in the window frame 10. The appearance of the raised and lowered window 1 can be maintained by preventing the interior surface from being scratched. When the lower shoji 30 is pushed into the slide open / close position, the abutting portion 452 of the trigger 45 abuts on the upper projecting portion 133 of the vertical frame 13 to disengage the engaging portion 453 and the biasing force of the coil spring 44 Thus, the latch bolt 42 protrudes to the locking position, so that the guide member 135 of the vertical frame 13 can be automatically locked by the latch bolt 42 without manual operation.

(2) Since the latch device 40 includes the trigger 45 that engages with the latch bolt 42, if the latch bolt 42 is supported by the latch body 41 so as to linearly move in the projecting and retracting direction. It is possible to prevent the latch bolt 42 from being caught during the projecting movement and to generate a large frictional force between the latch bolt 42 and the latch main body 41, and the durability and operational stability of the latch device 40 can be ensured. Further, since it is sufficient to guide the latch bolt 42 by the latch body 41 so that the latch bolt 42 moves linearly in the projecting and retracting direction, it is not necessary to provide an extra clearance in the guide member 135 of the vertical frame 13. The locking accuracy with 135 can be increased, and rattling of the lower shoji 30 can be prevented.

(3) Further, the abutting portion 452 of the trigger 45 in the latch device 40 abuts on the upper projecting portion 133 of the vertical frame 13 that constitutes an airtight line by abutting the AT material 231 of the vertical rod 23 in the upper shoji 20. Since the lower shoji 30 that has been turned over is pushed to the slide opening / closing position in the window frame 10, the appropriate height can be obtained without operating the contact portion 452 at a specific height position. By simply pushing the lower shoji 30 in position, the abutting portion 452 and the upper projecting portion 133 can be reliably abutted, and the operability of the inward return operation can be improved. Then, it is necessary to separately provide a contacted part for contacting the contact part 452 in the vertical frame 13 by bringing the contact part 452 into contact with the upper projecting part 133 constituting the airtight line of the upper shoji 20. Thus, an increase in the number of parts can be prevented and the appearance of the raising / lowering window 1 can be improved.

(4) Further, the trigger 45 of the latch device 40 is rotatably supported by the latch main body 41, and a contact portion 452 is formed on the distal end side of the latch bolt 42 with the rotation shaft 451 interposed therebetween. Since the engagement portion 453 is formed on the base end side of the contact portion 452, the contact portion 452 can be positioned at a portion close to the locking position between the latch bolt 42 and the guide member 135 of the vertical frame 13, and from the outside. The engaging portion 453 can be engaged with the notch 421 of the latch bolt 42 at a position where it enters the inside of the latch main body 41 which is not easily affected by the shock, and the engagement is prevented from being unintentionally released. The operational stability of the latch device 40 can be improved. In addition, since the abutting portion 452 of the trigger 45 is configured to protrude to the outside of the lower shoji 30, it is difficult for the user to touch the abutting portion 452 when tilted inward, and the abutting portion 452 is pushed unexpectedly. An erroneous operation that causes the latch bolt 42 to protrude can be prevented.

[Second Embodiment]
Next, the latch device 50 in the joinery according to the second embodiment of the present invention will be described with reference to FIG.
6A and 6B are cross-sectional views showing the operation of the latch device 50 in the joinery of the second embodiment.
The latch device 50 is different from the latch device 40 of the first embodiment in the configuration of the restricting member, and the other configurations are substantially the same. That is, the latch device 50 includes a latch main body 51 that is fixed to the upper collar 31 and the vertical collar 33 of the lower shoji 30, and a latch bolt 52 that serves as a locking member that is supported by the latch main body 51 so as to project and slide. A coil spring 54 as a first urging means for urging the latch bolt 52; a trigger 55 as a restricting member that engages with the latch bolt 52 in the non-locking position and restricts the protruding movement of the latch bolt 52; And a coil spring 56 as second urging means for urging the trigger 55.

  The latch bolt 52 protrudes from the latch body 51 as shown in FIG. 6 (A) and engages with the latch body 51 as shown in FIG. 6 (B). The latch bolt 52 is configured to be able to project and retract between a non-locking position where the lock with the vertical frame 13 is released, and an engagement portion 553 of a trigger 55 which will be described later is attached to the latch bolt 52.
