JP 2001-279983 A

  In the configuration of Patent Document 1, the shoji can be brought into close contact with the opening frame by the pulling action of the hook member that moves up and down while rotating as described above. The operability is also good. However, in this configuration, one end side of the hook member is pivotally supported with respect to the interlocking member that moves the hook member in response to the operation of the operation member, and the other end side of the hook member is a groove-like shape fixed to the opening frame side. Since it is slidably engaged with the cam via the cam follower, the structure of each component is complicated and the cost is high. And since the interlocking member and the hook member are connected by the axis | shaft, adjustment of the attachment position with respect to the opening frame of a locking device is difficult, and it is inferior to the workability | operativity of construction work.

  The present invention has been made in consideration of the above-described problems of the prior art, and can provide a lock device that can simplify the component structure and reduce the cost, and can easily perform the construction work, and the lock device. An object is to provide a joinery provided.

  The locking device according to the present invention is a locking device that locks a shoji that opens and closes around a rotation axis along one side of the opening frame with respect to the opening frame, and is attached to the opening frame or the saddle of the shoji. A base member, a hook member supported to be movable with respect to the base member and engageable with a receiving member fixed to the scissors collar or the opening frame, and the opening frame or the scissors collar An interlocking member that is supported so as to be slidable, and that moves by moving the hook member by receiving an operation force of an operation member provided on the opening frame or the shoji of the shoji.

If it does so, the position adjustment in the prospective direction between the receiving member by the side of a shoji and the locking device by the side of an opening frame can be performed easily. In addition, in a fitting with a structure in which a shoji is opened outside the door, it is difficult to visually recognize the mounting portion of the door, for example, by adjusting the position of the receiving member provided on the door toe of the shoji at the construction site. The workability is poor because it is necessary to extend the arm. On the other hand, in the fitting, since the position of the base member of the lock device can be adjusted with respect to the opening frame that can be easily attached from the indoor side, the position adjustment at the construction site is easy.

  In the fitting according to the present invention, the interlocking member is supported separately from the base member and supported by the opening frame, and the hook member is connected to the interlocking member so as to be relatively movable in the prospective direction. It may be a configured. If it does so, the connection state between an interlocking member and a lock member will not become an obstacle at the time of position adjustment of an expected direction of a base member.

  In the joinery according to the present invention, the interlocking member may be disposed in a pocket portion provided in the opening frame so as to face the outdoor side. If it does so, it can avoid that an interlocking member is visually recognized from the indoor side, and the appearance of joinery improves.

  According to the present invention, the shoji can be locked while being pulled toward the opening frame with a simple structure, and the cost can be reduced. In addition, the attachment positions of the base member and the hook member can be adjusted separately from the interlocking member that needs to be positioned with respect to the lock operation portion, and the construction work is facilitated.

  Next, the locking operation and action of the shoji 16 by the locking device 10 will be described.

  FIG. 8 is a diagram for explaining a locking operation by the locking device 10, and FIG. 8A is a diagram illustrating a state in which the locking device 10 is in the unlocked state and the shoji 16 is being closed. 8 (B) is a view showing a state in which the shoji 16 is closed from the state shown in FIG. 8 (A), and FIG. 8 (C) is a state in which the lock device 10 is locked from the state shown in FIG. 8 (B). It is a figure which shows the state which carried out.

  When the operation lever 20a of the lock operation unit 20 is pulled up, the lock device 10 is in the unlocked state as shown in FIG. In this state, the interlocking member 26 is in the downward movement position, and the guide pins 50 and 51 are positioned at the sliding start points 36b and 37b on the lower ends of the long holes 36 and 37, respectively, so that the hook member 32 is in the unlocked position. (See also FIG. 5A). For this reason, the nail | claw part 32b of the hook member 32 exists in the position which retracted from the lock | rock recessed part 28d (and cover recessed part 30d), and the lock | rock recessed part 28d is opened to the outdoor side.

  When the shoji 16 is closed in this state, the receiving member 22 and the engagement fitting 24 attached to the door rod 16c of the shoji 16 move toward the locking device 10 (see FIGS. 6 and 8A). When the closing operation of the shoji 16 is completed, the receiving pin 60 of the receiving member 22 is inserted into the lock recessed portion 28d, and the engaging piece 24c of the engaging metal fitting 24 engages with the recessed portion 44 (see FIG. 8B). .

  Therefore, the operation lever 20 a of the lock operation unit 20 is pulled down in order to lock the lock device 10. Then, as shown in FIG. 8C, the interlocking member 26 slides upward, and the interlocking member 26 pushes up the protruding piece 32d through the interlocking hole 26a, so that the hook member 32 moves upward.

That is, when the operation lever 20a of the lock operation unit 20 is pulled up, the interlocking member 26 is now slid downward, and the hook member 32 is located at the lower end side in the drawing as shown in FIGS. 8B and 8C. The guide pin 51 moves downward while rotating counterclockwise about the rotation axis. As a result, the hook member 32 becomes the unlocked position again, and the receiving pin 60 is allowed to be detached from the lock recess 28d, so that the shoji 16 can be opened (see FIG. 8A).

  As described above, the locking device 10 according to the present embodiment is supported on the base member 28 attached to the opening frame 14 and movably supported on the base member 28, and is fixed to the door toe 16 c of the shoji 16. The hook member 32 engageable with the receiving pin 60 of the receiving member 22 and the opening frame 14 are supported so as to be slidable, and are slid by receiving the operation force of the lock operation unit 20 provided on the opening frame 14. And an interlocking member 26 that moves the hook member 32. At this time, the base member 28 has a pair of long holes 36 and 37 into which a pair of guide pins 50 and 51 provided on one end side and the other end side in the moving direction of the hook member 32 are slidably inserted. In the long hole 36, the positions of the sliding start point 36b and the sliding end point 37b of the guide pin 50 are displaced in the expected direction.

  Thereby, in the locking device 10, the hook member 32 moves in the sliding direction of the interlocking member 26 while rotating around the guide pin 51 inserted in the long hole 37. For this reason, the long holes 36 and 37 for guiding the guide pins 50 and 51 provided in the hook member 32 can be locked while pulling the shoji 16 with a simple structure provided in the base member 28, and the cost can be reduced. In addition, since the hook member 32 is supported by the base member 28 and the interlocking member 26 is supported by the opening frame 14, the mounting position of the base member 28 and the hook member 32 can be adjusted with respect to the lock operation unit 20. It can be performed separately from the necessary interlocking member 26, and the construction work becomes easy.

  In the locking device 10, since the base member 28 is formed of a resin molded product, the moldability is good, and the sliding contact between the peripheral portions of the long holes 36 and 37 and the guide pins 50 and 51 becomes smooth at the same time. The generation of noise at the time can be suppressed, and the product quality is high.

  The lock device 10 further includes a metal cover member 30 that covers a part of the resin base member 28 and has an opening 42 that borders at least one of the long holes 36. Accordingly, for example, an external force in the opening direction (out-of-plane direction) is applied to the shoji 16 in a state where the shoji 16 is locked by the locking device 10, and the guide pin 50 is strong against the peripheral edge of the resin long hole 36. Even when pressed, the ribs 36a of the long holes 36 can be reinforced and supported by the openings 42 of the metal cover member 30, and the guide pins 50 can be supported. For this reason, even when the external force in the opening direction as described above is applied to the shoji 16, it is possible to prevent the lock device 10 from being damaged and being unlocked unintentionally.

  In the locking device 10, the notch 46 of the cover member 30 is disposed adjacent to the upper end side (near the sliding end point 37 c) of the other long hole 37. For this reason, in the locked state where the guide pin 51 is positioned at the upper end of the long hole 37, the other long hole 37 is also reinforced by the metal notch 46.

  In the locking device 10, the recessed portion 44 that can be engaged with the engagement piece 24 c of the engagement fitting 24 fixed to the door rod 16 c of the shoji 16 along with the receiving member 22 is used by using the bulging portion 30 e of the cover member 30. The engaging piece 24c is always engaged with the recess 44 when the shoji 16 is closed. As a result, for example, even when an external force in the in-plane direction is applied to the closed shoji 16, the metal engaging piece 24 c is supported by the metal bulging portion 30 e that forms the recess 44. It has high security performance. On the other hand, when the fitting 12 is used, for example, on a high-rise window or the like and it is not necessary to ensure the crime prevention performance from the outside, the engagement metal fitting 24 on the side of the shoji 14 may be omitted to reduce the cost. it can. In other words, the locking device 10 can improve its crime prevention performance simply by installing the engagement fitting 24 in accordance with its use environment, customer requirements, etc., and is highly versatile.

  In the lock device 10, the base member 28 is screwed and fixed to the opening frame 14 using an attachment hole 34 (40) that can adjust the attachment position in the prospective direction with respect to the opening frame 14. Thereby, position adjustment in the prospective direction between the receiving pin 60 on the shoji 16 side and the locking device 10 can be easily performed. Moreover, in the joinery 12 in which the shoji 16 opens to the outdoor side as shown in FIG. 1, adjusting the position of the receiving member 22 provided on the door rod 16c of the shoji 16 at the construction site visually recognizes the mounting portion. This is difficult, and it is necessary to extend the arm to the outdoor side through the opening frame 14, so that workability is poor. On the other hand, since the lock device 10 can adjust the position with respect to the opening frame 14 that can be easily attached from the indoor side, the position adjustment at the construction site is easy.

  Therefore, in the locking device 10, the interlocking member 26 is supported by the opening frame 14 separately from the base member 28, and the hook member 32 has its protruding piece 32 d inserted into the interlocking hole 26 a of the interlocking member 26. The interlocking member 26 is connected to the interlocking member 26 so as to be relatively movable in the prospective direction. For this reason, the connection state between the interlocking member 26 and the hook member 32 does not become an obstacle when adjusting the position of the base member 28 in the expected direction as described above.

  It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that the present invention can be freely changed without departing from the gist of the present invention.

  For example, in the above-described embodiment, the configuration in which the lock device 10 is provided on the opening frame 14 side and the receiving member 22 (and the engagement fitting 24) is provided on the shoji 16 side is illustrated. The receiving member 22 (and the engagement fitting 24) may be provided in the opening frame 14 provided in 16c.

  In the above embodiment, the hook member 32 is rotated and moved by shifting the positions of the sliding start point 36b and the sliding end point 36c of the one long hole 36 in the prospective direction. 36 may have a linear shape along the vertical direction, and the positions of the sliding start point 37b and the sliding end point 37c of the other long hole 37 may be displaced in the expected direction. Furthermore, the positions of the sliding start points 36b and 37b and the sliding end points 36c and 37c of both the long holes 36 and 37 may be shifted in the prospective direction.

  In the above embodiment, the base member 28 is provided with the long holes 36 and 37 and the hook member 32 is provided with the guide pins 50 and 51. However, the long holes 36 and 37 and the guide pins 50 and 51 are interlocked. When the hook member is moved by the member, it may be provided on either the base member or the hook member as long as the hook member can be moved in the sliding direction of the interlocking member while rotating around one guide pin.

  For example, like a locking device 10A shown in FIG. 9C, a base member 70 (and a cover member 72) (see FIG. 9A) in which guide pins 50 and 51 protrude from the surface, and a support plate portion 32a. It is good also as a structure provided with the hook member 76 (refer FIG. 9 (B)) which provided the long hole 36 in this, and provided the long hole 37 in the protrusion part 74 protruded from the downward direction of the support plate part 32a.
