Description

  The present invention relates to a sliding door device capable of opening the entire opening of a building as needed.

  There is known a sliding door device that combines a door bag body that is connected to one side of an opening of a building so as to be horizontally swingable, and a sliding door type sliding door that is linearly moved so as to appear in and out of the door bag body (for example, Patent Document 1). .

  The conventional sliding door device can open the entire opening by storing the sliding door type sliding door in the door pocket and horizontally swinging the door pocket, and there is no need to provide a door on a wall other than the opening. . That is, the horizontal upper bar is hung above the door bag body by the front and rear suspension wheels, and the two front and rear portions of the lower side of the door bar side of the upper bar are connected to the door side of the sliding door. Engage the support roller on the door butt side of the sliding door with the horizontal rail arranged inside the door, and engage the support roller on the inner door end side of the door bag body with the horizontal rail attached to the side surface of the sliding door. I support it. When the sliding door is moved in and out of the door pocket body, the support points by the two support rollers inside the door pocket body move relative to each other, so that the suspension load that suspends the sliding door door end side is substantially eliminated in the sliding door opening limit. The door end side of the sliding door can be easily separated from the upper bar to swing the door pocket body integrally with the sliding door, and the sliding door can be made to appear and disappear stably in the door pocket body.

JP 2010-24806 A

  According to this conventional technique, the sliding door suspends two places on the door-end side via the door-side, door-end-side suspension and the upper bar, and two sets of horizontal rails and support rollers are provided in the door pocket. Since it was deployed, there was a problem that the overall structure was extremely complex.

  Therefore, in view of the problems of the prior art, the object of the present invention is to provide a sliding door, a door-side suspension, a door-side door, an upper-end door-side steadying guide roller, and a lower-end door-side. By providing an auxiliary roller, it is providing the sliding door apparatus which can simplify the whole structure significantly.

  In order to achieve this object, the structure of the present invention is connected to a door frame attached to an opening of a building and a vertical frame on the door bottom side of the door frame so as to be horizontally swingable, and in a closed posture parallel to the door frame. The door frame that closes the door butt side half of the door frame and the sliding door that opens and closes the door frame side half of the door frame by moving linearly so as to appear in and out of the closed door bag body. The door side is suspended from a suspension car on a guide rail provided on the upper frame of the frame, and the door is supported on the door bottom side by running on the rail at the lower end of the door bag body and the guide material at the upper end of the door bag body. Combined with a guide roller for swinging the door bottom side, and when the auxiliary roller on the lower end door end rides on the block body on the lower end door end side of the door bag body in the opening limit of the sliding door, the engagement member on the suspension car side The gist is that the engaging member on the sliding door side that is being connected to the door rises in a separable manner.

  In addition, the suspension member side and the sliding door side engaging member can be locked inseparably via the lifting and dropping hardware mounted on the sliding door, and the sliding door can be locked by the lifting and falling hardware via the restraining member interlocked with the lifting and falling hardware. At the same time that the engaging member is releasably released, it can be restrained in the door pocket.

  Also, the suspension member side and sliding door side engaging members are locked inseparably via the lifting rod of the lock unit mounted on the sliding door, and the door bag body is closed via the latch rod of the latch unit mounted on the door bag body. The locking unit may release the engagement member in a separable manner in conjunction with the latch rod at the opening limit of the sliding door, and the sliding door has only the sliding door at the opening limit. A first restricting member that allows the operation of releasing the restraint of the door pocket body by the latch rod may be mounted. When the restraint of the door pocket body by the latch rod is released, the sliding door is opened via the first restricting member. The door bag body may be restrained, and the door bag body may be mounted with a second restricting member that permits the restraining operation of the door bag body by the latch rod only when the door bag body is in the closed posture.

  Note that the sliding door may be provided with a restriction roller for preventing the lift of the door roller on the upper end door bottom side, and a stopper that stops the sliding door to the open limit may be disposed on the upper frame.

  According to such a configuration of the invention, the sliding door is stably moved in a straight line via a door-side suspension car, a door-side door wheel, and a guide roller for steadying, and is a door bag body in a closed posture parallel to the door frame. The door frame side half of the door frame can be opened and closed. Further, the door bag body can open the entire interior of the door frame by swinging horizontally in an open posture integrally with the sliding door while storing the sliding door of the opening limit. On the other hand, when the sliding door is in the open limit, the auxiliary roller on the lower end door side rides on the block body on the lower end door end side of the door bag body, and the engaging member on the sliding door side that is connected to the engaging member on the suspension car side can be separated. Therefore, by swinging the door bag horizontally, the door tip side can be automatically separated from the suspension wheel to allow the door bag to swing.

  The auxiliary roller may be the same type of door as the door on the bottom edge of the sliding door, but it can be a simple circular shape as long as it can smoothly ride on the block on the door pocket and raise the door end of the sliding door. It may be a roller. In addition, each of the engaging members on the suspension vehicle side and the sliding door side that connect the door end side of the sliding door to the suspension vehicle can be used by combining, for example, a hook member that bends horizontally and a hat member that engages and disengages the hook member. The hook member and the hat member can be used on both the suspension wheel side and the sliding door side. However, the sliding door side engaging member, when the door bag body is closed in a closed position parallel to the door frame together with the open limit sliding door, engages with the hanging wheel side engaging member in the direction perpendicular to the sliding door side. When horizontally swinging, the sliding door side engagement member is separated from the suspension wheel side engagement member, and the engagement is released.

  By locking the hanging wheel side and sliding door side engaging members through the lifting hardware mounted on the sliding doors inseparably, there is no risk that the door end side of the sliding doors that are not at the open limit will be inadvertently separated from the hanging wheel and separated. . In addition, the suspension member side and the sliding door side engaging members shall be released in a separable manner by operating the raising and dropping hardware only when the sliding door is opened to the open limit and the door bag body is horizontally swung to the open position. . However, the raised and dropped hardware means the so-called French drop.

  The restraining member linked to the raised and lowered hardware releases the engaging member on the suspension vehicle side and the sliding door side in a separable manner via the raised and lowered hardware, and at the same time restrains the sliding door in the door pocket body, and the sliding door moves while the door bag body is swinging horizontally. It is possible to effectively prevent accidents that inadvertently escape from the door bag.

  The engagement member on the suspension door side and the sliding door side is locked inseparably via the lifting rod of the lock unit mounted on the sliding door, so that the sliding door door side is inadvertently suspended when the sliding door is outside the open limit. There is no risk of being disconnected from However, the lifting / lowering rod of the lock unit is always urged upward via a spring, for example, to lock the engagement members on the suspension and sliding doors inseparably, and opens the sliding door to the open limit to operate the latch unit. Then, when the restraint of the door bag body by the latch rod is released, the engagement member on the suspension vehicle side and the sliding door side is released in a separable manner in conjunction with the latch rod.

  The first restricting member mounted on the sliding door allows the releasing operation of the restraint of the door pocket body by the latch rod only when the sliding door is at the open limit, and when the sliding door is at the position other than the open limit, the restraint of the door pocket body is released. Prohibit operation. That is, when the sliding door is not in the open limit, there is no possibility that the restraint of the door bag body is released or the door bag body is not swung horizontally. Further, when the restraint of the door pocket body by the latch rod is released, the sliding door is restrained inside the door pocket body via the first restriction member, and there is a possibility that the sliding door may inadvertently come out from the door pocket body that is horizontally swinging other than the closed posture. Absent. Furthermore, the second restricting member mounted on the door bag body permits the door bag body to be restrained by the latch rod only when the door bag body is in the closed posture, and prevents the latch unit from being operated erroneously at other times.

  The restriction roller on the upper door end side of the sliding door prevents the door door side of the sliding door from being lifted during the moving operation of the sliding door, thereby preventing the door carriage from coming off the rail in the door pocket.

  The stopper disposed on the upper frame safely stops the sliding door to a predetermined opening limit, and improves the safety and reliability of the subsequent horizontal swing operation of the door bag body.

The horizontally rotating guide roller 34 rolls in the guide member 24a, and the vertically rotating regulating roller 35 is installed with a slight gap between the guide roller 34 and the top surface of the guide member 24a.

  The sliding door 30 can be linearly moved to the open limit so as to be accommodated in the door pocket space S of the door bag body 20, and the door end side half of the door frame 10 can be opened (solid lines in FIGS. 5 and 6). ). In the opening limit of the sliding door 30, the high cushion materials 31 b and 31 b on the door butt side of the sliding door 30 pass through openings (not shown) formed in the connecting plate 23 on the rear end of the door bag body 20, respectively, and the vertical frame 12 on the door butt side. The low cushion materials 31c and 31c are in contact with the connecting plate 23, respectively. Moreover, the sliding door 30 can be linearly moved to the door-end side so that it pulls out from the door bag body 20, and the door-end side half part of the door frame 10 can be closed (FIG. 1).

  A plate spring 15 for deceleration and a stopper 16 facing the suspension wheel 32 are fixed in the upper frame 11 in order to stop the sliding door 30 to the open limit, and the suspension wheel 32 corresponds to the plate spring 15. An engaging roller 32f is attached (FIGS. 5 and 7). 7A and 7B are an enlarged view of the main part of FIG. 5 and a schematic view of the main part corresponding to the Z1 arrow of FIG. 7A, respectively.

  The engagement roller 32f on the suspension vehicle 32 is mounted on the door bottom side of the bracket 32b of the suspension vehicle 32 via the bracket 32g (FIGS. 7 and 8). However, FIGS. 8A and 8B are a schematic diagram of the main part corresponding to the Z2 arrow in FIG. 7A and a schematic diagram of the main part in FIG. 7A, respectively.

  The leaf spring 15 is fixed to a mounting plate 14b for the guide rail 14 via a bracket 15a. The leaf spring 15 is supported horizontally toward the door butt side, and the distal end of the leaf spring 15 is bent downward in a V-shape, and just before the opening limit of the sliding door 30, it is on the outer periphery of the engagement roller 32f. It engages elastically and brakes the suspension wheel 32 appropriately. Further, when the engagement roller 32f passes through the V-shaped bent portion, the leaf spring 15 gently restrains the sliding door 30 to the open limit by dropping the V-shaped bent portion on the door end side of the engagement roller 32f.

  The stopper 16 is fixed on the guide rail 14 so as to face the leaf spring 15. A cushion material 16 a is attached to the tip of the stopper 16 on the door end side. The stopper 16 can contact the bracket 32g for the engagement roller 32f via the cushion material 16a to stop the suspension wheel 32 and stop the sliding door 30 to the open limit.

  When the sliding door 30 is moved to the open limit, the door bottom 33 on the door bottom side of the sliding door 30 rolls on the rail 25a at the lower end of the door bag body 20 and moves to the door bottom side (FIG. 5). Further, the auxiliary roller 36 on the door end side of the sliding door 30 moves to the lower end door end side of the door bag body 20, that is, immediately before the block body 25b at the front end side of the rail 25a, immediately before the opening limit of the sliding door 30 ( FIG. 9 (A), (B)). 9A is an enlarged schematic view of the main part of FIG. 3A, and FIGS. 9B and 9C are enlarged views of the main part of FIG.

  The upper surface of the block body 25b is formed in a mountain shape in a side view combining a steep slope on the door end side and a gentle slope on the door bottom side. Therefore, when the sliding door 30 advances to the open limit, the auxiliary roller 36 rides on the block body 25b (FIG. 9C) and can slightly raise the door end side of the sliding door 30. Accordingly, when the amount of increase δ of the sliding door 30 at this time is δ, the hat member 37 on the sliding door 30 side rises with respect to the hook member 32e of the suspension wheel 32 that suspends the door end side of the sliding door 30, and the hook member 32e, A gap δ can be formed between the hat members 37 (FIGS. 7A and 7B).

  Thereafter, the elevating head 38a of the raised and lowered hardware 38 on the sliding door 30 is lowered to release the hook member 32e and the hat member 37 in a separable manner (FIGS. 7A and 7B), and in the bending direction of the hook member 32e. When the sliding door 30 is moved horizontally (in the direction of the arrow in FIG. 7B), the sliding door 30 can be smoothly separated from the suspension wheel 32. When the raising / lowering head 38a of the raising / lowering hardware 38 is lowered, the hook 39b of the restraining member 39 is rotationally driven upward via a spring in the hinge fitting 39a, and the connecting plate 24 and the guide member 24a at the upper end of the door bag body 20 are driven. To the common engagement hole 24b (FIG. 7A), and the sliding door 30 is restrained in the door pocket body 20. In addition to the engagement hole 24b for the hook 39b of the restraining member 39, the coupling plate 24 and the guide member 24a are formed with a notch 24c corresponding to the restraining member 39 and the hinge fitting 39a on the door end side. .

  Subsequently, the upper and lower raising and lowering hardware 27, 27 of the panel body 22 of the door pocket body 20 is operated to release the restraint of the closed door pocket body 20, and the door pocket body 20 containing the sliding door 30 is hinged together with the sliding door 30. When it is horizontally swung through 26 (in the direction of the arrow K1 in FIG. 6), the sliding door 30 is automatically separated from the suspension wheel 32 to open the door bag body 20 and the door frame 10 can be fully opened ( The two-dot chain line in FIG. 6). Further, the door pocket body 20 in such an open posture is horizontally swung in the opposite direction by 90 ° to return to the original closed posture (in the direction of arrow K2 in FIG. 6, solid line), and through the raised and lowered hardware 27 and 27. If the hook member 32e and the hat member 37 are locked to be separable via the raised and lowered hardware 38 and the restraint of the sliding door 30 by the restraining member 39 is released, the sliding door 30 is pulled out of the door bag body 20 and the door frame 10 The door end side half can be opened and closed.

  In the above description, the upper and lower raising and lowering hardware 27, 27 of the door bag body 20 may be operated at a time in conjunction with each other. Further, the auxiliary roller 36 of the sliding door 30 may be a simple circular roller. Further, the hook member 32e on the suspension car 32 side and the hat member 37 on the sliding door 30 side can be provided opposite to each other on the sliding door 30 side and the suspension car 32 side, respectively. You can also. In other words, the engaging members on the suspension wheel 32 side and the sliding door 30 side can be arbitrarily changed in specific form as long as the respective functions can be realized.

Other embodiments

  The door bag body 20 is constrained to a closed posture parallel to the door frame 10 via a latch unit 41 that is embedded and mounted on the door end side of the front panel body 21 instead of the upper and lower raised metal pieces 27 and 27. (FIG. 10). In addition, a lock unit 42 that embeds and locks the engagement member on the suspension wheel 32 side and the sliding door 30 side in an inseparable manner is mounted on the upper end portion of the sliding door 30 in place of the raising and dropping hardware 38, When the sliding door 30 is opened to the open limit, the lock unit 42 can release the sliding door 30 so as to be separated from the suspension wheel 32 in conjunction with the latch unit 41. However, in FIG. 10, the door frame 10, the door bag body 20, and the sliding door 30 are connected to the vertical frame 12 on the door bottom side via the upper and lower pivot hinges 51 and 52 so as to be horizontally swingable. The configuration is basically the same as that of the embodiment.

  The latch unit 41 can lift and lower the upper and lower latch rods 41b and 41b simultaneously and symmetrically by rotating the handle 41a protruding from the surface of the panel body 21 by 90 °, for example, forward and backward (FIG. 10, FIG. 11). That is, the latch unit 41 restrains the door bag body 20 in a closed posture by causing the heads 41c and 41c at the tips of the upper and lower latch rods 41b and 41b to protrude upward and downward to the upper frame 11 and the floor F, respectively, , 41c can be retracted from the upper frame 11 and the floor surface F to release the door bag body 20 so as to be horizontally swingable. The lower head 41c penetrates the guide bush 41d at the lower end of the panel body 21 from above to below, and the upper head 41c passes through the guide bush 41d at the upper end of the panel body 21 from below to above. The front end of an engagement fitting 43 that projects horizontally below the middle part of the upper frame 11 is engaged (FIGS. 11 and 12).

The long holes 45e and 45e are formed. In addition, the stepped connecting plate 24 at the upper end of the door pocket body 20 has a cutout corresponding to the bracket 45a and the swing metal fitting 45 from the upper side of the door pocket space S for housing the sliding door 30 to the lower edge of the panel body 21 side. It is assumed that a notch is formed.

  On the upper end surface of the sliding door 30, a long L-shaped material 46 for supporting the swing metal fitting 45 from below is mounted. The L-shaped material 46 is continuous from the door end side of the sliding door 30 to the immediate vicinity of the guide roller 34 on the door bottom side (FIGS. 10 and 13), and swings only when the sliding door 30 is opened to the open limit. The metal fitting 45 is swingable downward, and the downward latch rod 41b is allowed to descend. That is, the L-shaped member 46 is a first restricting member that allows the latch rods 41b and 41b to release the restraint of the door bag body 20 only when the sliding door 30 is in the open limit. However, the L-shaped member 46 only needs to be able to prevent the swinging metal fitting 45 from swinging downward when the sliding door 30 is outside the open limit, and a bar member, pipe member, or the like having an arbitrary cross-sectional shape may be used.

  On the other hand, the connecting pin 45c penetrating the head 41c on the latch rod 41b protrudes long on the swing member 44b side of the restriction unit 44 (FIGS. 13 and 15), and the swing member as the latch rod 41b moves up and down. 44b is displaced up and down. Therefore, the swinging member 44b allows the latch rod 41b to rise only when the door bag body 20 is in the closed posture and is horizontally rotated inward. That is, the swing member 44b is a second restricting member that permits the restraining operation of the door pocket body 20 by the latch rods 41b and 41b only when the door pocket body 20 is in the closed posture. The swing member 44b can be changed to any form other than that shown in the figure as long as such a restricting operation can be performed.

  The lock unit 42 at the upper end of the sliding door 30 includes a lifting member 42e penetrating the hook member 32e on the suspension wheel 32 side and the hat member 37 on the sliding door 30 side (FIGS. 10 and 17). The raising / lowering rod 42a is assembled | attached with respect to the common bracket 42c with the drive rod 42b so that raising / lowering is possible mutually parallel (FIG. 17, FIG. 18).

  The elevating rod 42a and the drive rod 42b are connected via a connecting member 42d, and one end of the connecting member 42d on the drive rod 42b side is supported by a horizontal stud 42e on the bracket 42c so as to be vertically rotatable. The drive rod 42b is urged upward via a compression spring 42f attached to the lower small diameter portion. The elevating rod 42a and the drive rod 42b are connected to the connecting member 42d in such a manner that the connecting pins 42a1 and 42b1 are inserted into the long holes of the connecting member 42d, respectively, and one end of the connecting pin 42a1 on the elevating rod 42a side is The elevating direction of the elevating rod 42a is regulated by being inserted into a vertical hole 42c1 formed in the bracket 42c. Further, a reinforcing plate 42g for screwing the hat member 37 through the elevating rod 42a is screwed to the upper end of the bracket 42c.

  When the upper end of the drive rod 42b is free, the elevating rod 42a is driven upward via the compression spring 42f, the drive rod 42b, and the connecting member 42d. Therefore, the lock unit 42 can lock the hat member 37 and the hook member 32e through the lifting rod 42a so as not to be separated. On the other hand, when the drive rod 42b is pushed downward (in the direction of the arrow in FIG. 17), the elevating rod 42a is lowered via the connecting member 42d and removed below the hat member 37 and the hook member 32e. 32e is released in a separable manner. The elevating rod 42a passes through the hook member 32e through a flanged bush 32e2.

  The upper and lower pivot hinges 51 and 52 are assembled to the upper and lower ends on the door bottom side of the panel body 22 on the back of the door bag body 20 (FIG. 19). However, FIGS. 19A and 19B are an enlarged view of a main part of FIG. 10 and a view corresponding to the arrow W4 in FIG. 19A, respectively.

  The upper pivot hinge 51 is formed as a central suspension by combining a downward hinge pin 51a on the door frame 10 side and a receiving body 51b on the door bag body 20 side. The hinge pin 51a is fixed to the mounting plate 51a1, and the mounting plate 51a1 is mounted in the upper frame 11 via a reinforcing plate 51a2 and a large support plate 51a3. A receiving body 51b for the hinge pin 51a is supported upward via a bracket 51c with an adjusting screw 51c1, and the bracket 51c is assembled to the panel body 22 via a mounting plate 51c2 and a reinforcing plate 51c3. The lower half of the hinge pin 51a is inserted in a bushing-equipped receiver 51b so as to be relatively rotatable, and the position of the receiver 51b can be adjusted in the width direction of the panel body 22 via an adjusting screw 51c1.

  The lower pivot hinge 52 combines a thrust bearing 52a on the door frame 10 side, a hinge pin 52b with a flange, and an arm 52c on the door bag body 20 side. The thrust bearing 52a is embedded upward at the front end of an L-shaped bracket 52a1 that is screwed to the lower end of the vertical frame 12 on the door bottom side, and the lower surface of the bracket 52a1 is provided with a support material 52a2 embedded in the floor surface F. Is supported through. The hinge pin 52b inserts the lower shaft into the thrust bearing 52a and prevents it from being removed via a set screw on the shaft center, inserts the upper shaft into the seat of the arm 52c, and sits on the thrust bearing 52a. The total weight of the door bag body 20 and the sliding door 30 is transmitted to the thrust bearing 52a. The arm 52c is assembled to the panel body 22 via a reinforcing member 52c1.

  The door bag body 20, together with the sliding door 30 at the open limit, has a closed posture (solid line in FIG. 20) parallel to the door frame 10 and a right angle to the door frame 10, with the hinge pins 51 a and 52 b of the upper and lower pivot hinges 51 and 52 as the rotation center. Can be horizontally swung between the open position (two-dot chain line in FIG. 20). However, only the hinge pin 51a of the upper pivot hinge 51 is shown in FIG. In addition, on the door bottom side of the door bag body 20, there are front and back sealing materials 28, 28 that close the space between the door bottom side of the door bag body 20 in the closed position and the vertical frame 12 via the connection plate 23 and the auxiliary connection plate 23 a. It is mounted vertically.

  The outline of the interlocking operation between the latch unit 41 mounted on the door bag 20 and the lock unit 42 mounted on the sliding door 30 is as follows.

  When the sliding door 30 is pulled out in the closing direction from the door bag body 20 constrained in the closed posture, the hat member 37 on the sliding door 30 side and the hook member 32e on the hanging wheel 32 side are connected via the lifting rod 42a of the lock unit 42. It is locked so as not to be separated (FIGS. 17 and 21A). At this time, the swing metal fitting 45 on the door bag 20 side cannot interfere with the L-shaped member 46 on the sliding door 30 side and cannot swing downward, and the head 41c and the latch rod 41b connected to the swing metal fitting 45 are The operation of releasing the restraint of the door bag body 20 is prevented.

  When the sliding door 30 is opened to the open limit (FIG. 21B), the drive rod 42b of the lock unit 42 moves directly below the swing metal fitting 45, and the swing metal fitting 45 is connected to the L-shaped member 46 on the sliding door 30 side. The tip on the door end side can be removed and swinged downward. Further, on the door end side of the sliding door 30, the auxiliary roller 36 at the lower end rides up and rises on the block body 25b on the lower end door end side on the door bag body 20, and a gap is formed between the hat member 37 and the hook member 32e. .

  Therefore, when the latch unit 41 is operated to release the restraint of the door pocket body 20 by the latch rods 41b and 41b, the head 41c of the upward latch rod 41b is lowered (FIGS. 22A and 22B) and swings downward. The drive rod 42b of the lock unit 42 is pushed down by the swinging metal fitting 45 that moves, the lift rod 42a is lowered via the connecting member 42d, and the hat member 37 and the hook member 32e are released in a separable manner. At this time, the connecting pin 45c that connects the swing metal fitting 45 and the head 41c moves to a position lower than the swing member 44b that is horizontally rotated inward. Further, since the swing metal fitting 45 crosses the door end side of the L-shaped material 46 diagonally downward, the sliding door 30 cannot be pulled out from the door bag body 20 and is restrained in the door bag body 20.

  Subsequently, when the door bag body 20 is horizontally swung with the sliding door 30 toward the open position (FIGS. 23A and 23B), the hat member 37 is smoothly separated from the hook member 32e, and the door bag body 20 Along with the horizontal swing, the swing member 44b rotates horizontally until the swing member 44b moves away from the leg piece 43b of the engagement fitting 43 and comes into contact with the bent piece 44e, and is positioned above the connecting pin 45c and the latch rod 41b and the head 41c. The ascent is prevented and erroneous operation of the latch unit 41 is prevented. FIG. 23B clearly shows that the swing metal fitting 45 crosses the door tip side of the L-shaped member 46 on the sliding door 30 side obliquely downward and restrains the sliding door 30 in the door bag body 20. Yes.

  The door bag body 20 together with the sliding door 30 can be swung horizontally as it is and opened in an open position (two-dot chain line in FIG. 20). Further, the door bag body 20 is closed from the open position to the closed position, and then the latch unit 41 is operated and restrained to the closed position via the latch rods 41b and 41b, thereby the hat member 37, The hook member 32e is locked so as not to be separable, and the sliding door 30 can be pulled out from the door bag body 20 in the closing direction, and the operation of each part during this period is shown in FIGS. 23 (A), (B) to 22 (A), (B ) And FIG. 21 (B), the process proceeds to FIG. 21 (A). However, in FIG. 21 to FIG. 23, some constituent members of the door bag body 20 and the sliding door 30 are illustrated in a transparent manner to facilitate understanding of the operation of each part.

  In the above description, the sliding door 30 may be configured to be an automatic closing type by driving the suspension wheel 32 to the door end side via a drive unit that uses a spiral spring, for example, and relaxes the moving speed at the time of automatic closing. Therefore, an appropriate braking unit may be installed on the door end side of the upper frame 11. Further, the sliding door 30 may be locked in a fully closed state. The door bag body 20 may be provided with a regulating member between the door frame 10 in order to restrict the horizontal swing limit and appropriately regulate the opening posture. You may combine the door closer urged | biased to the attitude | position side. In addition, the function of the restricting member can be integrated into the door closer.
