  In the conventional example shown in Patent Document 1, an endless flexible strip is formed along the four sides of the sash frame by operating the handle in order to protrude or retract the guide member on which the shoji door is supported from the sash frame. Must be moved. For this reason, when the shoji door is large or heavy, a large force is required to protrude the shoji door from the sash frame.

  In the conventional example shown in Patent Document 2, since the door frame, the slide guide member, and the door are connected by a total of three hinges in the vertical direction, the door protrudes in the prospective direction with respect to the door frame while maintaining a parallel state. Or it cannot be pulled in.

  An object of the present invention is to provide a joinery which can easily project or retract a shoji in parallel from a frame and can easily slide the shoji in the projecting state.

  The joinery of the present invention includes a first frame member and a second frame member facing each other, and a frame body having a third frame member and a fourth frame member that connect both ends of the first frame member and the second frame member. A first rail member and a second rail member which are provided so as to be movable in a prospective direction with respect to the first frame member and the second frame member, and are arranged to face each other, and the first rail member and the second rail member. A shoji that is guided and moves along the longitudinal direction of each rail member, and is provided between the first frame member and the first rail member, and the first rail member is in a prospective direction with respect to the first frame member. A first link mechanism that is moved between the second frame member and the second rail member, and a second link mechanism that moves the second rail member in a prospective direction with respect to the second frame member; Of the first rail member by the first link mechanism. An interlocking mechanism that interlocks the movement in the insertion direction and the movement of the second rail member in the prospective direction by the second link mechanism, and the interlocking mechanism is coupled to the first link mechanism, A first linkage bar provided reciprocally along the longitudinal direction of the frame member, and a second linkage bar connected to the second link mechanism and reciprocally movable along the longitudinal direction of the second frame member. It is characterized by having a linkage bar and a third linkage bar that connects the first linkage bar and the second linkage bar and is reciprocally movable along the longitudinal direction of the third frame member.

In the present invention having this configuration, in order to open the shoji with respect to the frame, first, an appropriate place of the shoji is pushed to project the shoji together with the rail member toward the prospective direction, for example, outdoors, with respect to the frame. Then, the interlocking mechanism operates together with the first link mechanism and the second link mechanism. In the interlocking mechanism, the first linkage bar connected to the first link mechanism moves along the longitudinal direction of the first frame member, and the second linkage bar connected to the second link mechanism moves in the longitudinal direction of the second frame member. Move along. At this time, since the first linkage bar and the second linkage bar are connected to the third linkage bar, the first linkage bar, the second linkage bar and the third linkage bar are interlocked. By interlocking these first to third linkage bars, the movements of the first link mechanism and the second link mechanism are synchronized, and the shoji is in the expected direction with respect to the frame body together with the rail member, for example, It sticks out towards the outdoors.
Thereby, since the shoji moves in the prospective direction of the frame, ventilation or the like can be performed through the gap between the shoji and the frame while disposing the shoji in front of the opening of the frame. Furthermore, since the shoji can be moved from the front of the opening of the frame by sliding the shoji with respect to the rail member and performing an opening operation, the opening window of the joinery is opened.
In order to close the shoji with respect to the frame, the shoji is slid to the closing position with respect to the rail member, and then the rail member is pulled into the frame. Then, as described above, the first link mechanism, the second link mechanism, and the interlocking mechanism operate. However, in the interlocking mechanism, the first linkage bar, the second linkage bar, and the third linkage bar are opposite to those described above. Will move in the direction. Even when the opening of the joinery is closed, these linkage bars move together to synchronize the movements of the first link mechanism and the second link mechanism, and the shoji is drawn into the frame together with the rail member.

Therefore, in the present invention, the first link mechanism and the second link mechanism are provided between the first frame body, the second frame member, the first rail member, and the second rail member. Since the two-link mechanism is linked with the first linkage bar, the second linkage bar, and the third linkage bar, the pair of rail members move by the same amount, so that the shoji is pushed out or pulled in while maintaining parallelism. Can do. Moreover, in order to move the rail member in the expected direction with respect to the frame, it is only necessary to press an appropriate place of the shoji, so that the opening operation of the window can be performed more easily than when the handle is operated. In other words, in the conventional example in which the shoji door is projected by moving the endless flexible strip along the four sides of the sash frame, a large force is applied to the handle itself to rotate the flexible strip. Otherwise, the shoji door cannot be ejected or retracted, but in the present invention, the first link mechanism, the second link mechanism and the interlocking mechanism are interlocked and the shoji is protruded in parallel simply by pressing the front of the shoji. .
In addition, in the present invention, in the state where the rail member protrudes from the frame, a gap is formed between the shoji and the frame in a prospective direction, so that the room is ventilated through this gap. In addition, in the state where the space formed between the pair of rail members is blocked by a shoji, the movement of people and objects inside and outside the room is restricted, so privacy protection and crime prevention, and further from inside the room This is preferable for restricting the fall of objects to the outdoors.

  In the joinery of the present invention, the first link mechanism includes a swing link having one end rotatably supported by the first rail member and the other end pivotally connected to the first linkage bar. A pivot link having one end portion pivotably supported by an intermediate portion of the swing link and the other end portion pivotably supported by the first frame member, and the second link mechanism includes: One end is pivotally supported by the second rail member and the other end is pivotally connected to the second linkage bar, and one end rotates around an intermediate portion of the swing link.

[Guide mechanism]
12 and 14, the guide mechanism 40 includes a guide piece portion 41 that protrudes from the lower frame member 12 to the outdoor side, and a guide roller 42 that rolls on the upper surface of the guide piece portion 41. . In FIG. 1, two guide mechanisms 40 are provided on both ends of the lower frame member 12. However, in the present embodiment, one or more guide mechanisms 40 may be added to the central portion of the lower frame member 12. . That is, the installation location of the guide mechanism 40 is not limited to 2 locations, and may be 3 locations or more.
The guide roller 42 includes an attachment piece 421 whose base end is fixed to the lower surface of the horizontal portion 223 of the second rail member 22, and a roller main body 422 provided at the distal end on the chamber side of the attachment piece 421. .

[Operation of this embodiment]
In the joinery 1 of the present embodiment, in order to fully open the window, the locking handle 35 is rotated so that the rail members 21 and 22 can protrude and the shoji 30 can slide. Therefore, the locking handle 35 is rotated 180 ° to move the base member 361 and the first to third link plates 383, 384, 385. Then, the lock pin 381 is detached from the receiving member 382 and the pin member 366 is detached from the receiving member 387. Thereafter, the shoji 30 is pushed out of the frame body 10 together with the upper and lower rail members 21 and 22 with an appropriate place, for example, the locking handle 35.
By pushing out the shoji 30, the interlocking mechanism 60 operates together with the first link mechanism 51 and the second link mechanism 52.

In the first link mechanism 51, when the rail member 21 is projected together with the shoji 30, the swing link 53 rotates around one end portion that is rotatably connected to the rail member 21. Since one end portion of the rotation link 54 is rotatably connected to the intermediate portion of the moving link 53, the other end portion of the swing link 53 moves along the longitudinal direction of the upper frame member 11. . One end portion of the swing link 53 connected to the rail member 21 moves straight toward the chamber side so as to be perpendicular to the longitudinal direction of the rail member 21. The first link mechanisms 51 provided at the three locations push the rail member 21 straight out toward the outside in a state in which the first link mechanism 51 is maintained parallel to the upper frame member 11.
The second link mechanism 52 operates in the same manner as the first link mechanism 51. In other words, when the rail member 22 is projected together with the shoji 30, the swing link 53 rotates around one end portion rotatably connected to the rail member 22, but the swing link 53 rotates. Since the movement is restricted by the moving link 54, the other end of the swing link 53 moves along the longitudinal direction of the lower frame member 12, and the one end of the swing link 53 is in the longitudinal direction of the rail member 22. Move straight toward the outside so that it is at a right angle to. The second link mechanisms 52 provided at the three locations push the rail member 22 straight out toward the outside in a state in which the second link mechanism 52 is maintained in parallel with the lower frame member 12.

The first linkage bar 61 connected to the other end portion of the swing link 53 of the first link mechanism 51 moves along the longitudinal direction of the upper frame member 11, and the swing link of the second link mechanism 52. The second linkage bar 62 connected to the other end of the ring 53 moves in the opposite direction to the first linkage bar 61, but the first linkage bar 61 and the second linkage bar 62 are each in a corner. The first linkage bar 61, the second linkage bar 62, and the third linkage bar 63 are integrated in one direction, because they are connected by the third linkage bar 63 via the connecting member 65 for use in FIG. Move clockwise.
When the rail member 22 protrudes from the frame body 10, the guide roller 42 provided at the lower portion of the rail member 22 rolls on the upper surface of the guide piece portion 41 attached to the lower frame member 12.

When the shoji 30 is projected out of the frame 10 together with the rail members 21 and 22, it is in the semi-closed position. The shoji 30 is slid from the semi-closed position to the open position to open the window. FIG. 15 shows a state immediately after the shoji 30 is slid. In FIG. 15, the guide mechanism 40 is not shown.
The shoji 30 slides smoothly because the upper roller portion 23 provided on the upper collar 31 is guided by the rail member 21 and the lower roller portion 24 provided on the lower collar 32 is guided by the rail member 22.

In order to close the window, the space 20 of the upper and lower rail members 21, 22 is closed with the shoji 30, and then the shoji 30 is pulled forward with the locking handle 35. Then, the rail members 21 and 22 that hold the shoji 30 are drawn into the frame body 10.
When the rail members 21 and 22 are pulled into the frame body 10, the first link mechanism 51 and the second link mechanism 52 operate in the reverse manner to the above, and the first linkage bar 61, the second linkage bar 62, and the third linkage bar. 63 also moves in the opposite direction to that described above, and in FIG. Thereby, the shoji 30 is pulled into the frame 10 together with the rail members 21 and 22 while maintaining the parallel state.
When the shoji 30 is drawn into the frame body 10, the locking handle 35 is operated to lock it.

  Further, in this embodiment, the locking handle 35 is turned by 90 ° so that the rail members 21 and 22 can be protruded and the shoji 30 cannot be slid, and the shoji 30 is moved up and down with respect to the frame 10. The rail members 21 and 22 are pushed out of the room. In this state, although the shoji 30 is in a position protruding from the frame 10, the space 20 between the upper and lower rail members 21 and 22 is closed, so that the shoji 30 and the frame 10 are between the shoji 30 and the frame 10. Only space will result. The space is used for indoor ventilation.

[Effect of this embodiment]
Therefore, in the present embodiment, the following operational effects can be achieved.
(1) Rail members 21 and 22 that are provided so as to protrude parallel to the frame body 10 toward the outside of the frame body 10 and are arranged in parallel to each other, and a shoji 30 that slides along the longitudinal direction of these rail members 21 and 22. A first link mechanism 51 provided between the upper frame member 11 of the frame body 10 and the first rail member 21 and extending and retracting the first rail member 21 while being parallel to the upper frame member 11; A second link mechanism 52 provided between the frame member 12 and the second rail member 22 and extending and retracting the rail member 22 while maintaining parallel to the lower frame member 12, a first link mechanism 51 and a second link mechanism And an interlocking mechanism 60 that interlocks the protrusion and immersion of the rail members 21 and 22 with the 52, and the interlocking mechanism 60 is connected to the first link mechanism 51 and can reciprocate along the longitudinal direction of the upper frame member 11. The first phosphorus provided in A first linkage bar 61, a second linkage bar 62 connected to the second link mechanism 52 and reciprocally movable along the longitudinal direction of the lower frame member 12, and the first linkage bar 61 and the second linkage bar 62. The vertical frame member 14 has a third linkage bar 63 that can be reciprocated along the longitudinal direction. Therefore, when the shoji 30 is projected or pulled out from the frame body 10, the amount of movement in the indoor / outdoor direction is the same between the rail member 21 and the rail member 22, so that the shoji 30 can be pushed out or pulled in while maintaining parallelism. . Furthermore, since the rail members 21 and 22 and the shoji 30 are configured to be accommodated in the frame body 10, it is not necessary to separately provide the frame body 10 with rails and door pockets for sliding the projecting shoji 30. Therefore, the expected width of the frame 10 can be reduced, and not only the appearance becomes good, but also the labor for constructing rails and door pockets can be saved. Furthermore, since it is the structure which slides the shoji 30, it can clean the outer surface of the shoji 30 from the room.

(2) The first link mechanism 51 includes a swing link 53 having one end rotatably supported by the first rail member 21 and the other end movably engaged in the longitudinal direction of the upper frame member 11; One end of the swing link 53 is rotatably supported and the other end of the swing link 53 is rotatably supported by the upper frame member 11. Similarly, the second link mechanism 52 has one end rotatably supported by the second rail member 22 and the other end moved in the longitudinal direction of the lower frame member 12. A swing link 53 that is freely engaged, and a swing link 54 that has one end portion rotatably supported by an intermediate portion of the swing link 53 and the other end portion rotatably supported by the lower frame member 12. And the other end of the swing link 53 is connected to the second linkage bar 62, That is infested while maintaining a parallel precisely with the rail members 21 and 22 children 30 can be realized with a simple structure using the swing links 53 and pivot link 54.

(3) The first linkage bar 61 and the third linkage bar 63 are connected by a corner connecting member 65, and the corner connecting member 65 is fixed to a connecting portion between the upper frame member 11 and the vertical frame member 14. Guided by the guide member 66. Therefore, when transmitting the advance / retreat of one of the first linkage bar 61 and the third linkage bar 63 arranged in directions orthogonal to each other to the other, the corner connecting member 65 moves along the guide member 66 while being curved. Therefore, the movement of the first linkage bar 61 and the third linkage bar 63 can be accurately linked. Similarly, the second linkage bar 62 and the third linkage bar 63 are connected by a corner connecting member 65, and the corner connecting member 65 is fixed to the connecting portion between the lower frame member 12 and the vertical frame member 14. Since the structure is guided by the member 66, the movement of the second linkage bar 62 and the third linkage bar 63 can be accurately interlocked.

(4) Since the end portion of the first rail member 21 and the end portion of the second rail member 22 are open ends where the shoji 30 can be slid, the opening of the window can be enlarged even with one shoji 30. it can. For example, in a normal window in which two sliding screens are slidably arranged on the window frame, the opening amount can be obtained only by a half of the frame opening, but in this embodiment, at the end of the rail members 21 and 22 Since the open end that allows sliding of the shoji 30 is provided, an opening amount that is 1/2 or more of the frame opening can be obtained.

(5) In order to move the shoji 30, an upper roller portion 23 that rolls along the first rail member 21 is provided on the upper arm 31 of the shoji 30, and along the second rail member 22 on the lower arm 32 of the shoji 30. Since the lower roller portion 24 that rolls is provided, sliding along the rail members 21 and 22 of the shoji 30 can be performed smoothly.

(6) Each of the rail members 21 and 22 has a cross-sectional shape in which corner portions 22A and 22B facing each other are formed on the inner side, and the upper roller portion 23 and the lower roller portion 24 are respectively formed on the corner portions 22A. Since the roller body 241 with which only the circumferential surface abuts and the roller body 242 with which the circumferential surface abuts only on the corner portion 22B, the rail members 21 and 22 of the shoji 30 have less play when moving, and the shoji 30 can be moved smoothly.

(7) Since the locking handle 35 is provided on the shoji 30, the shoji 30 and the rail members 21 and 22 are locked when the shoji 30 and the rail members 21 and 22 are slid with respect to the rail members 21 and 22. The handle 35 can be operated and the window can be opened and closed easily.

(8) Provided with a guide mechanism 40 for guiding the second rail member 22 to protrude and retract from the frame body 10, and the guide mechanism 40 includes a guide piece portion 41 provided to protrude to the outdoor side of the lower frame member 12; The guide rail 42 is provided on the second rail member 22 and rolls on the upper surface of the guide piece portion 41. For this reason, when the rail members 21 and 22 and the shoji 30 are protruded or retracted from the frame body 10, these loads are supported by the guide mechanism 40, so that the first link mechanism 51 and the second link mechanism 52 Such a supporting load can be reduced. Therefore, an unnecessary load is not applied to the first link mechanism 51 and the second link mechanism 52, so that the deformation of the first link mechanism 51 and the second link mechanism 52 can be prevented.

It is not something. For example, in order to move the shoji 30 smoothly, a conventional door wheel having a horizontal rotation axis may be provided on the lower arm 32.
In the embodiment, the guide piece portion 41 constituting the guide mechanism 40 is constituted by a member different from the lower frame material 12, but the guide piece portion of the present invention is constituted by a part of the lower frame material 12. May be used. Further, in the case where the guide piece portion 41 is formed of a member different from the lower frame member 12, the guide piece portion is protruded from the lower frame member when the size of the prospective direction of the lower frame member is large. I don't need it. Furthermore, it is not limited to what attaches another member which comprises the guide piece part 41 to the lower frame material 12, It may attach to other than the lower frame material 12, for example, the housing of an outer wall.

The attachment position of the locking handle 35 is not limited to the central portion in the height direction of the vertical rod 34 of the shoji 30 but can be set as appropriate in relation to the attachment position of the joinery 1. A handle for pushing out or retracting the shoji 30 may be provided separately from the locking handle.
Further, it is not always necessary to provide the guide mechanism 40 for guiding the lower rail member 22 to protrude and retract from the frame body 10.
