Description

  The present invention relates to a double-acting open / close door that includes a slide door and a swing door, and that can open and swing the slide door that has been moved to the open position together with the swing door to fully open the opening.

  This type of opening / closing door is known, for example, from Patent Document 1. In this case, the slide door is slidably opened and closed by a first guide rail fixed to the opening frame and a second guide rail provided on a rotating door (swinging door). The slide door is provided with a runner that is guided by the first guide rail and a roller train that is guided by the second guide rail. The length of the first guide rail is set to the same length as the width of the slide door, the runner is suspended by the first guide rail, and the runner is separated from the first guide rail to the upper part of the slide door. The posture can be changed to the stored standby posture. Therefore, a structure for switching the runner between the operating posture and the standby posture is required.

  According to the double-acting opening / closing door of Patent Document 1, in the state where the sliding door is opened to the open position and the runner is switched to the standby position, the sliding door is swung along with the rotating door to completely open the opening. It can be opened. The open / close door includes a lock mechanism for restricting the swing door from swinging when the slide door is opened and closed, and the slide door is pulled out of the swing door when the swing door is swinged open / closed. Another locking mechanism is provided between the doors. This type of double-acting door is also disclosed in Patent Documents 2 and 3.

Japanese Patent No. 4229748 (paragraph numbers 0029 to 0032, FIG. 1) Japanese Patent Laid-Open No. 06-58037 (paragraph number 0011, FIG. 4) Japanese Utility Model Sho 60-91778 Microfilm (page 8, line 15 to page 9, line 9, Fig. 5)

  According to the open / close door of Patent Document 1, the slide door can be slid to the swing door side to be opened to the open position, and if a wider opening width is required, the slide door and the swing door can be opened. The door can be swung and fully opened. Similarly, in the open / close doors of Patent Document 2 and Patent Document 3, the slide door can be opened to the half-open position, and the slide door and the swing door can be opened to the fully open position.

  However, in the double-acting open / close doors of Patent Documents 1 to 3, since the open / close door is configured by two door panels of the slide door and the swing door, the opening width in the state where the slide door is opened to the open position (effective) (Opening width) is less than half of the full opening width of the opening frame. For example, when the total opening width of the opening frame is 1300 mm, the effective opening width is only less than 580 mm. Therefore, when entering and exiting with a wheelchair, an assistant enters and exits while supporting a user who gets off the wheelchair. Even in such a case, it is necessary to swing the sliding door and the swinging door to the fully open position. In addition, in the open / close door of Patent Document 1, a structure for switching the runner between the operating posture and the standby posture is required, so that the structure for moving the open / close door becomes complicated, and the overall cost increases accordingly.

  Originally, this kind of opening and closing doors, because the effective opening width when the sliding door is opened is insufficient, because each door is swung open to the fully open position to secure the necessary opening width, There is no problem with its function. However, as described above, it is unsatisfactory for a user who uses a wheelchair on a daily basis, and it is desired to be able to more easily enter and exit the entrance / exit provided with the open / close door.

  In order to increase the width of the opening that can be entered and exited in the half-open state, the inner width of the opening frame can be increased. However, in that case, it is inevitable that the entire opening / closing door becomes large and costs increase. In addition, the opening width of the opening frame of the open / close door provided in the house is determined by the structure of the building frame such as the width of the corridor and the opening width of the entrance and exit, so it is not possible to increase the opening width of the opening frame unnecessarily. However, there is a strong demand to improve the usability of the open / close door in an opening frame having a relatively small opening width. In particular, in the case of installing an opening / closing door using an existing opening, in most cases, the opening width of the opening frame cannot be enlarged, so that it becomes more difficult to improve the usability.

The object of the present invention is to increase the effective opening width in a state where the sliding door is opened, even for an opening portion having a relatively small opening width, so that the wheelchair user and the assistant can open and close the door, and the opening portion. It is an object to provide a double-acting opening / closing door that can be easily moved in and out and is excellent in usability.

It can be opened and closed while being supported. The second door 3 has a state in which the second runner 19 and the second roller 20 are supported by the second guide rail 12 and the second guide frame 14, or two first rollers 20 have the second guide frame. 14 can be opened and closed while being supported by 14. That is, two of the three transition bodies provided on the doors 2 and 3 are always guided and supported by the guide rails 11 and 12 and / or the guide frames 13 and 14 so as to be opened and closed. In this way, when the two transition bodies are always guided by the guide rails 11 and 12 and the guide frames 13 and 14, the doors 2 and 3 can be opened and closed based on a stable support state. The first door 2 and the second door 3 can be opened and closed smoothly and lightly compared to a double-acting door. Furthermore, it is only necessary to provide three transition bodies for each door 2 and 3, and it is not necessary to provide a structure for switching the runner between the operating posture and the standby posture. Can be reduced. The operational reliability can be improved with the simplification of the transition structure.

  If the swing lock mechanism can be automatically unlocked by the release tool 37 provided in the door 3 during the opening movement of the second door 3, it is possible to save the user himself from switching the swing lock mechanism. Can do. Similarly, if the slide lock mechanism is automatically switched to the locked state in conjunction with the swinging door 4 being opened, the user can save the trouble of switching the slide lock mechanism. Therefore, a series of operations when the first door 2 and the second door 3 are slid open and closed and then the swing door 4 is opened and closed can be simplified to reduce the user's operation burden. The door can be opened and closed.

  According to the double-acting opening / closing door provided with the catch structure for capturing the capturing body 78, the first door 2 that has been opened to the open position is temporarily held by the catch structure, and the first door 2 moves toward the closed position. It can be restricted from moving. In other words, the catch structure closes the opened first door 2 and keeps it immovable regardless of whether or not the slide lock mechanism is switched to the locked state. Therefore, when the swing door 4 is opened, It is possible to reliably prevent the first door 2 and the second door 3 from being pulled out of the retracted position on the rear surface of the swing door 4 and improve the safety of the double-acting door. Further, by incorporating the latch body 91 and the latch spring 92 into the slide lock mechanism, the catch structure can be simplified and its cost can be reduced. This is because it is not necessary to prepare a case or housing dedicated to the catch structure, and the catch structure and the slide lock mechanism can reduce the number of parts by using the catch body 78 provided on the first door 2 as a common catch target. It is.

Located in. In other words, even if the first door 2 and the second door 3 are moved to the open position, the swing lock mechanism is not completely switched to the unlocked state, and the swing door 4 is clearly displayed by the user. The doors 2, 3, and 4 can be opened and swinged only after the swinging is opened. Therefore, at the same time when the first door 2 and the second door 3 are moved to the open position, the swinging door 4 is opened and swinged, and the balance of the wheelchair user's posture is lost and an accident such as a fall can be prevented. The safety of double-acting doors can be improved.

  According to the lock body 71 that engages and captures the locked body 80, the detection body 72 and the detection spring 73, and the cam structure or the like, the lock body 71 depends on the open / close state of the swing door 4. Can be automatically switched between the locked posture and the unlocked posture. Specifically, after the first door 2 and the second door 3 are opened, the slide lock mechanism is automatically switched to the locked posture in conjunction with the swinging door 4 being opened. Can be captured by the lock body 71, and the first door 2 and the second door 3 can be closed and locked so as not to move. Therefore, it is possible to reduce the user's operation burden when opening the first door 2 and the second door 3 and further swinging and opening the swing door 4, especially when a wheelchair user enters and exits the opening. Operation can be simplified and the usability of the door can be further improved.

  In the state in which the door recess 7 for accommodating the upper part of the swing door 4 and the runner recess 8 are provided in the opening frame 1 and both the first and second doors 2 and 3 are opened, the door recess 7 and the runner recess 8 If the outer surface is covered with the upper part of the swing door 4, the appearance of the open / close door can be made a clean impression. In a state where both the first and second doors 2 and 3 are opened to the open position, the first runner 16 and the second runner 19 separated from the first and second guide rails 11 and 12 are exposed in the runner recess 8. Therefore, the apparent impression may be complicated. However, when the entire runner recess 8 is covered with the swinging door 4, the appearance of the appearance can be made clear. In addition, when the first and second doors 2 and 3 are both closed, the upper part of the swing door 4 is accommodated in the door recess 7 and covers the runner recess 8, so that the double-acting opening and closing with a three-sheet structure Improving the appearance of the door.

  When the open relay body 47 is formed using the inclined wall of the first bracket 25 and the open passive body 48 is formed using the end face on the closed end side of the first frame bracket 23, the open relay body 47 and the open passive body are formed. Compared with the case where 48 is provided as a dedicated part, the interlocking structure can be simplified and the cost can be saved. Further, since the opening relay body 47 and the opening passive body 48 are formed using the first bracket 25 and the first frame bracket 23 having excellent rigidity, even when the first door 2 is opened wildly, There is no possibility that the open relay body 47 and the open passive body 48 are damaged or deformed, and the interlocking function can be maintained for a long time.

  The first transition body 105 is opened and closed along the first and third guide rails 107 and 111 adjacent to the left and right, and further along the second and fourth guide rails 108 and 112 adjacent to the left and right. According to the opening / closing structure for opening and closing the second transition body 106, the number of components of the rail structure and the transition bodies 105 and 106 can be reduced, and the opening / closing structure can be remarkably simplified. In addition, by simplifying the opening / closing structure, the manufacturing cost of the double-acting opening / closing door can be reduced, and the labor required for construction can be reduced.

  When an opening / closing interlocking structure including a pair of pulleys 132, a transmission body 134, and a pair of front and rear coupling tools 135 and 136 is provided between the first door 2, the second door 3, and the swing door 4, the second door 3 can be opened and closed simultaneously with the opening and closing operation of the first door 2. Therefore, it is not necessary to open and close the first door 2 and the second door 3 separately, and the opening and closing operation of both the doors 2 and 3 can be easily performed. In addition, when the opening / closing operation of the first door 2 is sequentially transmitted through the relay structure, it is inevitable that a collision sound or an impact will be generated in the relay structure part. The first door 2 and the second door 3 can be opened and closed silently. Furthermore, since the first door 2, the second door 3, and the swing door 4 are connected to each other via the opening / closing interlocking structure, the opening / closing interlocking structure functions as a swing prevention structure, and the slide opening / closing is performed. At times, it is possible to restrict the lower portions of the first and second doors 2 and 3 from swinging in the front-rear direction. In the fully closed state, the second door 3 can be restricted from moving toward the closed end by the open / close interlocking structure.

  When the pulley 132 and the transmission body 134 are assembled in the mounting groove 141 provided in the lower part of the second door 3, compared to the case where the opening / closing interlocking structure is arranged between the lower surface of the second door 3 and the floor surface. The gap between the lower surface of the second door 3 and the floor surface can be reduced. Further, when the linear transition portion of the transmission body 134 is positioned above and below the mounting groove 141, the entire opening / closing interlocking structure can be accommodated within the thickness range of the second door 3, so that the appearance of the double-action type opening / closing door is simplified. It can be made clean. Further, by housing the opening / closing interlocking structure in the mounting groove 141, the structure is prevented from being exposed to the outside of the second door 3, and for example, foreign matter is caught between the wire 134 and the pulley 132, thereby opening / closing interlocking. It is possible to reliably prevent malfunctions that impair the function.

  When the pulley 132 is pivotally supported by the pulley holder 130 and the pair of pulley holders 130 are connected to both ends of the guide frame 131 to form these three units as unit parts, the assembly of the opening / closing interlock structure to the mounting groove 141 is performed. The attaching operation can be easily performed with less effort. Further, by fixing the coupling tools 135 and 136 to a pair of sliders 139 and 140 guided and supported by the guide frame 131, the coupling tool 135 can be used when the first and second doors 2 and 3 are opened and closed. Since the guide frame 131 can regulate the swinging up and down, the reciprocating slide operation of the coupler 135 can be performed smoothly.

  When each connecting tool 135 and 136 is connected to the lower mounting shaft 165 of the lower runner base 164 and the lower runner base 164 is attached to the lower holder 163 embedded and fixed to the first door 2 and the swing door 4, the opening / closing interlocking is performed. The connection between the structure and the doors 2 and 4 can be easily performed with one touch. Regardless of the level of skill of the operator, simply attaching the lower runner base 164 to the lower holder 163 can properly connect the open / close interlocking structure and the doors 2 and 4 to reduce the labor required for construction. Construction costs can be reduced.

  When the transfer guide body 185 is provided at the adjacent end of each guide rail 107, 108, 111, 112, the transfer guide body 185 assists the transfer of the first and second transition bodies 105, 106 between the adjacent rails. The transfer between the rails of both transition bodies 105 and 106 can be performed more smoothly. Therefore, the first door 2 and the second door 3 can be opened and closed easily and smoothly.

  When the fixed rail unit 103 including the first and second guide rails 107 and 108 and the movable rail unit 104 including the third and fourth guide rails 111 and 112 are formed of a common rail material, Each rail unit 103 and 104 can be formed at low cost. In addition, by forming the rail units 103 and 104 with a common rail material, the structure of each guide rail serving as a transfer partner can be made the same, and transfer between adjacent rails can be performed accurately. When the swing door 4 is closed, if the door support 194 provided on the opening frame 1 supports the swing rail 4 near the swing tip of the movable rail unit 104, the tilting moment acting on the hinge 5 is reduced. Thus, it is possible to reliably prevent the swinging tip of the swinging door 4 from tilting to the floor surface side. Since the tilting moment acting on the hinge 5 can be reduced, the hinge 5 is not worn out at an early stage.

  When the rocking | fluctuation prevention body 61 and the urging | biasing spring 62, the fixed engagement body 63, etc. comprise a rocking | fluctuation lock mechanism, and the release tool 37 which carries out lock release operation of the rocking | fluctuation prevention body 61 is provided in the 2nd door 3 side, By simply moving the second door 3 to the open position, the rocking block 61 can be automatically unlocked. Accordingly, it is possible to reduce the user's operational burden when opening the first door 2 and the second door 3 and further swinging and opening both the doors 2 and 3 together with the swinging door 4. A series of operations when entering and exiting can be simplified to improve the usability of the double-acting door.

  According to the lock body 71 that engages and captures the locked body 80, the detection body 72 and the detection spring 73, and the cam structure or the like, the lock body 71 depends on the open / close state of the swing door 4. Can be automatically switched between the locked posture and the unlocked posture. Specifically, after the first door 2 and the second door 3 are opened, the slide lock mechanism is automatically switched to the locked posture in conjunction with the swinging door 4 being opened. Can be captured by the lock body 71, and the first door 2 and the second door 3 can be closed and locked so as not to move. Therefore, it is possible to reduce the user's operation burden when opening the first door 2 and the second door 3 and further swinging and opening the swing door 4, especially when a wheelchair user enters and exits the opening. Operation can be simplified and the usability of the door can be further improved.

  When the first and second transition bodies 105 and 106 are unitized by a transition frame 115 and a plurality of open / close runners 116, and these transition bodies 105 and 106 are fixed by an upper mounting shaft 125 provided on the upper runner base 124. The mounting work of each transition body 105 and 106 can be easily performed with one touch.

Thus, the second roller 20 in the vicinity of the second runner 19 rides on the second guide frame 14, and immediately after that, the second runner 19 separates from the second guide rail 12. Further, when the first door 2 is opened, the first door 2 and the second door 3 move to the open position as shown in FIG. The weights of the first door 2 and the second door 3 in this state are all supported by the swing door 4 as shown in FIG. 9, and only in this state, the three doors 2, 3, 4 are swing open. can do.

  In order to smoothly open and close the first door 2 and the second door 3, the swing door 4 is locked so as not to swing between the free end of the swing door 4 and the upper frame 1 c of the opening frame 1. A rocking lock mechanism is provided. Further, a slide lock mechanism for restricting the opening operation of the first door 2 is provided between the swing base end of the swing door 4 and the first door 2 so that the three doors 2, 3, 4 swing. When opened, the first door 2 and the second door 3 are restricted from sliding out toward the closed position. Further, the slide lock mechanism is provided with a catch structure that engages and captures the first door 2 opened to the open position and temporarily holds the first door 2 in the open position.

  10 and 11, the rocking lock mechanism includes a case 60 embedded in the rear surface of the free end of the rocking door 4, and a plate-like rocking blocking body 61 supported by the case 60 so as to be vertically slidable. A pair of left and right biasing springs 62 that push up and bias the swing prevention body 61 upward, and a fixed engagement body 63 embedded in the upper frame 1c corresponding to the swing prevention body 61, and the like. A triangular passive piece 64 projecting rearward of the case 60 is integrally provided on the rear surface of the rocking block 61 and the biasing spring is provided by a release tool 37 provided on the second runner 19. By pushing down while resisting the urging force of 62, the rocking block 61 can be switched to the unlocking posture.

  The rocking block 61 is guided by a guide pin 66 fixed to the case 60 with a vertical slide groove 65 provided on the plate surface, and further, the passive piece 64 is slid and guided by a guide window 67 opened in the case 60. Therefore, only vertical sliding is supported. The passive piece 64 is formed with a slope cam 64a, and the release tool 37 is formed with an operation surface 37a having the same inclination angle as that of the slope cam 64a. The fixed engagement body 63 is formed with an engagement groove 63 a that allows the rocking prevention body 61 to enter and exit in a vertically penetrating manner.

  When the swing door 4 is in the closed position, the swing prevention body 61 is pushed up by the urging spring 62 as shown in FIG. 10 and its upper end engages with the engagement groove 63 a of the fixed engagement body 63. doing. Therefore, even if an external force in the direction of swinging outward is applied to any of the three doors 2, 3, and 4, the swinging door 4 does not swing open and can maintain a closed posture. it can. Therefore, the first door 2 and the second door 3 can be smoothly opened and closed. In the state where the first door 2 and the second door 3 are opened to the open position, the operation surface 37a of the release tool 37 rides on the inclined cam 64a of the passive piece 64 as shown in FIG. The piece 64 is pushed down while resisting the biasing force of the biasing spring 62. As a result, the engagement state between the swing prevention body 61 and the engagement groove 63a of the fixed engagement body 63 is released, and the restraint state of the swing door 4 can be released. As described above, the swing lock mechanism is automatically unlocked by the release tool 37 provided on the second door 3 in a state where the first door 2 and the second door 3 are opened to the open position.

  12 to 14, the slide lock mechanism detects a housing 70 fixed to the swing door 4 via a bracket 69, a lock body 71 accommodated in the housing 70, and an open / closed state of the swing door 4. The detection body 72 and the detection spring 73 to be performed, and a cam structure that converts the retracting operation of the detection body 72 into the attitude changing operation of the lock body 71 are configured.

  The housing 70 is made of a plastic molded product having a T-shape when viewed from the side. An operation section 74 that opens downward and a spring section 75 that opens laterally toward the vertical frame 1b are formed in the housing 70, and a lower surface thereof is formed. An engaging recess 76 is formed in a partial arc shape. The slide lock mechanism uses the lock shaft (locked body) 80 of the capturing body 78 provided at the open end of the first door 2 as a capturing target and prevents the first door 2 from closing. As shown in FIG. 6, the capturing body 78 includes a capturing frame 79 that is fixed to the open end of the first frame 15 and opens upward, and a lock shaft 80 that is fixed to the front and rear walls of the frame 79. I have. The lock shaft 80 is fixed to the first frame 15 so as to be positioned below the bottom wall of the first frame 15.

  The lock body 71 is formed of a press fitting integrally provided with a front and rear wall and one side end wall, and engages and captures the lock shaft 80 at the lower end corner of the front and rear wall in cooperation with the previous engagement recess 76. A lock notch 77 is formed in a quadrant. Further, cam grooves 86 having a cam structure, which will be described later, are formed in a reverse letter shape on the front and rear walls of the lock body 71 (see FIG. 12). The lock body 71 is accommodated in the operation section 74 and can slide up and down between a lower locked posture and an upper unlocked posture.

  The detection body 72 is made of a metal fitting having a cross-shaped front view, with spring receiving pieces 83 protruding above and below a shaft portion 82 having a quadrangular cross section, and a relief groove 84 is formed on the retreat end side of the shaft portion 82. It is. The detection body 72 is supported by the front and rear walls and the left and right walls of the spring section 75 so as to be slidable left and right, and is biased by the detection spring 73 in a direction in which the advance end 85 advances from the housing 70. As shown in FIG. 12, the detection body 72 when the swinging door 4 is in the closed posture has its advancing end 85 received by the vertical frame 1b on the open end side, and the entire detection body 72 is detected. The housing is retracted into the housing 70 against the biasing force of the spring 73. As shown in FIG. 14C, when the swing door 4 is in the open posture, the detection body 72 is advanced toward the outside of the housing 70 by the detection spring 73.

  A cam structure is provided between the detection body 72 and the lock body 71 in order to switch the lock body 71 by using the above-described withdrawal operation of the detection body 72. The cam structure includes a reverse-shaped cam groove 86 provided on the front and rear walls of the lock body 71, an operation pin 87 fixed to the retracted end of the detection body 72, and a horizontal guide formed on the front and rear walls of the housing 70. A groove 88 is used. The operation pin 87 can be slid left and right along the guide groove 88, and the cam groove 86 is operated during that time to displace the lock body 71 up and down.

  When the detection body 72 is retracted into the housing 70 against the detection spring 73, the operation pin 87 is located at the groove end of the horizontal groove 86a of the cam groove 86, so that the lock body 71 is unlocked upward. The posture is switched (see FIG. 12). Further, when the detection body 72 is advanced to the outside of the housing 70 by the detection spring 73, the operation pin 87 is positioned at the upper end of the inclined groove 86b of the cam groove 86 as shown in FIG. The body 71 descends to the lower surface of the housing 70 and switches to the locked posture, and the lock notch 77 cooperates with the engagement recess 76 to engage and capture the lock shaft 80 of the capture body 78. Therefore, after the lock body 71 is switched to the locked position, the first door 2 does not move to the closed position side, and the first door 2 and the second door 3 are swung along with the swing door 4. It can be opened. In this way, the slide lock mechanism is automatically switched to the unlocked state in conjunction with the opening of the swing door 4 and can lock the holding body 78 provided on the first door 2.

  The lock body 71 in the above-mentioned slide lock mechanism is not switched to the locked posture until the swing door 4 is slightly opened. Therefore, when the swinging door 4 is swingably opened, the first and second doors 2 and 3 may slide out due to the inertial force before the lock body 71 captures the lock shaft 80. is there. In order to eliminate such problems, a catch structure is provided inside the slide lock mechanism.

  The catch structure includes a latch body 91 whose target is the lock shaft 80 described above, and a latch spring 92 that biases the latch body 91 to the engagement and capture posture. The latch body 91 is made of an inverted pentagonal plate-like plastic molded product. The lower surface of the latch body 91 cooperates with a guide surface 93 for facilitating passing of the lock shaft 80 and an engagement recess 76 of the housing 70, so An oblique catch surface 94 for capturing is provided. The latch body 91 and the latch spring 92 are housed in the operation section 74 together with the lock body 71, and the latch body 91 slides up and down independently in the escape groove 84 provided in the shaft portion 82 of the detection body 72.

  An inverted trapezoidal escape hole 95 is formed in the front and rear penetrating shape on the plate surface of the latch body 91, and the operation pin 87 fixed to the detection body 72 crosses the escape hole 95 forward and backward. Accordingly, as shown in FIG. 12, when the detection body 72 is retracted into the housing 70, the latch body 91 moves up and down against the latch spring 92 and is opened to the open position. The lock shaft 80 of the door 2 can be captured and the door 2 can be temporarily held in the open position. However, when the swinging door 4 is opened and the detection body 72 is advanced to the outside of the housing 70, the upper corner portion of the escape hole 95 is received by the operation pin 87 as shown in FIG. Therefore, the latch body 91 is maintained in the posture in which the lock shaft 80 is captured, and the latch body 91 does not move upward and switch to the capture release posture.

  The first door 2 that has been opened to the open position is supported by the first guide frame 13 via the left and right first rollers 17 provided at the upper end thereof. Therefore, the first door 2 may rattle up and down around the first roller 17 on one side. In order to prevent such rattling of the first door 2, as shown in FIGS. 6 and 7, a magnet 57 is fixed to the lower part of the small edge surface on the open end side of the first door 2, A magnetic metal plate 58 is fixed to the lower part of the small edge surface on the hanging side so that the first door 2 can be fixed and held by the magnetic adsorption action of both 57 and 58. The magnet 57 and the magnetic metal plate 58 also serve to reinforce the function of the catch mechanism. In some cases, the magnet 57 and the magnetic metal plate 58 can be used in place of a mechanically configured catch mechanism.

  Next, the operation of each member when opening and closing the double-acting door will be described. As shown in FIG. 3, when the first door 2, the second door 3, and the swing door 4 are in the closed state, the first door 2 is in contact with the first runner 16 and the first roller 17. It is suspended by the guide rail 11 and the first guide frame 13. In this state, when the first door 2 is opened by grasping the handle 6, only the first door 2 is slid open as shown in FIG. 15A, and the open end of the first door 2 is the second door 3. When the open end of the open relay body 47 is reached, the open relay body 47 contacts the open passive body 48. Meanwhile, the first roller 17 moves in the opening direction while being guided by the first guide frame 13 provided on the second door 3, and the first roller 17 in the vicinity of the first runner 16 is supported by the first guide frame 13. The Thereafter, as shown in FIG. 15B, the second door 3 moves along with the first door 2 in the opening direction.

  When the first door 2 is further opened from the above state, the first runner 16 is detached from the first guide rail 11 as shown in FIG. 16 immediately before the first door 2 and the second door 3 reach the open position. Further, the second runner 19 is detached from the second guide rail 12. In this state, the first runner 16 and the second runner 19 are located in the runner recess 8, and the lock shaft 80 of the capture body 78 provided on the first door 2 is engaged and captured by the latch body 91. . Further, the rocking prevention body 61 of the rocking lock structure is switched to the unlocking posture by being pushed down by the release tool 37. By opening the swing door 4 in this state, the entire opening frame 1 can be swing open. In this state, the detection body 72 is moved outward from the housing 70 and described above. As described above, the slide lock mechanism is switched to the locked state.

  When the swing door 4 that has been swing open is returned to the closed position as shown in FIG. 17A, the detection body 72 is again received by the vertical frame 1 b on the open end side and retreats into the housing 70. Therefore, the slide lock mechanism is switched to the unlocking posture. In this state, when the handle 6 is grasped and the first door 2 is closed, the latch body 91 is first pushed up against the urging force of the latch spring 92 by the lock shaft 80, and is captured and engaged by the latch body 91. The state is released, and only the first door 2 moves in the closing direction. Then, when most of the first door 2 comes out of the rear surface of the second door 3, the closing relay body 49 contacts the closing passive body 50 of the second door 3. In the meantime, the first runner 16 moves onto the first guide rail 11, and the first roller 17 near the first runner 16 is detached from the first guide frame 13 of the second door 3. This state is shown in FIG. 17 (b). Thereafter, the second door 3 can accompany the first door 2 and move in the closing direction.

  Soon after the second door 3 moves along with the first door 2 and closes, the release tool 37 is separated from the slope cam 64a of the passive piece 64, so that the swing preventing body 61 is pushed up by the biasing spring 62. Thus, the fixed engagement body 63 is engaged to restrict the swing of the swing door 4. By continuously closing the first door 2, the entire opening surrounded by the opening frame 1 is closed with the first door 2, the second door 3, and the swinging door 4 as shown in FIG. It can be closed with. Since the first contact body 54 of the second door 3 in this state is received by the second contact body 55 provided on the swing door 4, the second door 3 is prevented from moving to the closing side more than necessary. Can be regulated.

  As described above, according to the open / close door having the three-piece structure including the first door 2, the second door 3, and the swing door 4, the first door 2 and the second door 3 are opened as shown in FIG. The effective opening width B <b> 2 in the state where it is opened to the position exceeds a half value of the total opening width B <b> 1 of the opening frame 1. Specifically, the effective opening width B2 when the total opening width B1 is 100 is 54. Compared to the conventional two-door opening / closing door, when the total opening width B1 of the opening frame 1 is 1300 mm, the effective opening width is 702 mm. it can. Further, when the swing door 4 is opened and swinged while seated in a wheelchair, the swing door 4 is opened while approaching each of the doors 2 to 4 whose swing radius is smaller than that of the conventional open / close door. Therefore, the opening / closing operation of the door can be performed more easily and easily.

  In the above embodiment, the opening relay body 47 is brought into contact with the opening passive body 48 at the final stage of the opening stroke of the first door 2, but this is not necessary, and the opening relay structure is the opening of the first door 2. The operation can be configured to be transmitted to the second door 3 after the middle of the opening stroke of the door 2. Even in such a case, the second door 3 can be accompanied by the first door 2 and the opening operation can be performed while the opening speed of the first door 2 is accelerated to some extent. For the same reason, the closing relay structure can be configured to transmit the closing operation of the first door 2 to the second door 3 after the middle part of the closing stroke of the door 2. The open relay body 47 and the open passive body 48 can be configured as dedicated components in the same manner as the closed relay body 49 and the closed passive body 50.

  In addition to the above, the locked body 80 provided in the first door 2 does not need to have the structure described in the embodiment, and may be any structure as long as it can be engaged and captured by the lock body 71. The lock body 71 does not need to have a structure that switches between a locked posture and an unlocked posture by sliding displacement, but has a structure that switches between a locked posture and an unlocked posture by swinging and displacing vertically, horizontally, or diagonally. There may be. Similarly, the detection body 72 may have a structure that switches between a retracted posture and an advanced posture by swinging displacement. A lock can be provided on the contact surface between the vertical frame 1a on the closed end side and the first door 2, so that the first door 2 can be locked so as not to be opened. As a lock in that case, a sickle lock, a cylinder lock, a latch, or the like can be applied.

(Example 2) FIG. 18 shows Example 2 of a double-acting open / close door in which the swing lock mechanism is changed. In this case, the point that the engagement roller 100 that engages and disengages with the engagement groove 63a of the fixed engagement body 63 is provided on the upper part of the rocking prevention body 61 is different from the previous embodiment. In detail, the roller bracket 98 was fixed to the upper part of the rocking | fluctuation prevention body 61, and the engagement roller 100 was rotatably supported by the roller shaft 99 which bridges the right-and-left wall of the bracket. Further, an engagement groove 63a through which the engagement roller 100 can enter and exit is provided in the fixed engagement body 63, and the engagement roller 100 is pushed down against the urging force of the urging spring 62 at the lower end front portion of the engagement groove 63a. The engaging / disengaging guide surface 101 is formed in an inverted C shape. Since others are the same as the previous embodiment, the same reference numerals are assigned to the same members, and descriptions thereof are omitted.

  In the swing lock mechanism according to FIG. 18, the passive piece 64 of the swing preventing body 61 is provided on the second runner 19 in the state where the second door 3 is moved to the open position, as in the above embodiment. The release tool 37 is pushed down against the biasing spring 62. However, as indicated by a solid line in FIG. 18A, the upper half of the engagement roller 100 is located in the engagement groove 63a even in this unlocked state. Therefore, in order to open the swing door 4, the handle 6 of the first door 2 is strongly pulled outward and the engagement roller 100 is pushed down on the engagement / disengagement guide surface 101 while the engagement door 100 is pushed down. It is necessary to operate so as to pass through the lower surface of the guide surface 101.

  In other words, the swing lock mechanism cannot be completely switched to the unlocked state simply by moving the first door 2 and the second door 3 to the open position, and the swing is not performed until the user has a clear intention. The door 4 can be swingably opened. Therefore, at the same time when the first door 2 and the second door 3 are moved to the open position, the swinging door 4 opens and swings, thereby preventing an accident such as the balance of the wheelchair user being out of balance and falling. Can improve safety. When the swing door 4 is closed, the passive piece 64 is received by the release tool 37 of the second runner 19, so that the handle 6 is pushed inward strongly, contrary to when the door is opened. Then, the engagement roller 100 is operated so as to pass through the lower surface of the engagement / disengagement guide surface 101.

Reference Example 1 FIG. 19 shows Reference Example 1 of a double-acting opening / closing door in which the swing lock mechanism is changed. There, a suction recess 9 was formed in a portion adjacent to the runner recess 8 of the door recess 7 of the opening frame 1, and a magnet sheet (magnet) 96 was fixed thereto. Further, in a state where the hat-shaped iron plate (magnetic metal plate) 97 is fastened to the panel surface of the swing door 4 facing the suction recess 9 with a screw and the swing door 4 is closed, the iron plate 97 is attached to the magnet sheet 96. To be fixed by adsorption. As the magnet 96, a commercially available magnet catch or magnet may be used in addition to the magnet sheet. Since others are the same as the previous embodiment, the same reference numerals are assigned to the same members, and descriptions thereof are omitted.

  As described above, if the rocking lock mechanism is composed of the magnet sheet 96 and the iron plate 97, the overall structure can be simplified, the number of parts can be reduced, and the manufacturing cost can be reduced as compared with the rocking lock mechanism mechanically constructed. Further, since the swing door 4 is held in the closed position by the magnetic adsorption action of the magnet sheet 96 and the iron plate 97, the swing door 4 can be used unless the user swings and opens the swing door 4 with a clear intention. Can be kept in the closed position. Accordingly, similar to the swing lock mechanism described with reference to FIG. 18, the swing door 4 is opened and swinged at the same time when the first door 2 and the second door 3 are moved to the open position. Prevents accidents such as loss of balance and falling, and improves the safety of double-acting doors.

( Third Embodiment ) FIGS. 20 to 36 show a third embodiment of the double-acting door. In the third embodiment, front and rear, left and right, and up and down follow the cross arrows shown in FIG. 20 and FIG.

In the state where the first door 2 and the second door 3 are opened to the open position, the front surface of the second door 3 is covered with the swing door 4, and a part of the closed end side of the first door 2 is the swing door. 4 is exposed laterally from the side surface on the free end side. By providing the handle 6 at this exposed portion, the first door 2 can be closed from the open position without being obstructed by the second door 3 and the swing door 4.

  The vertical dimension of the swing door 4 is set larger than the vertical dimension of the first door 2 and the second door 3, and the upper part of the swing door 4 is positioned above the upper ends of the first door 2 and the second door 3. Is supported. As shown in FIG. 21, in order to accommodate the swinging door 4 in the closed state in the opening frame 1, an upper part of the upper frame 1c of the opening frame 1, an upper part of the swinging door 4, and a movable rail unit described later. The door recessed part 7 which accommodates 104 is recessed and formed (refer FIG. 21). As described above, when the first door 2 and the second door 3 are opened to the open position, the front surface of the second door 3 is completely covered with the swinging door 4 so that the appearance of the open / close door is clean. You can make an impression.

  In order to open and close the first door 2 and the second door 3, the fixed rail unit 103 is fixed in a state of being embedded in the lower part of the upper frame 1 c (see FIG. 23), and the movable rail unit is mounted on the upper rear surface of the swing door 4. 104 is provided (see FIG. 24). A first runner body (first transition body) 105 is provided on the upper end surface of the first door 2, and a second runner body (second transition body) 106 is provided on the upper end surface of the second door 3. The movable rail unit 104 is fixedly supported by three cantilevered support fittings 113 fixed to the upper part of the swing door 4. A side wall fixed to the side end surface of the swing door 4 is integrally formed on the support fitting 113 that supports the suspension side of the swing door 4 (see FIG. 27).

  In FIG. 23, the fixed rail unit 103 is an aluminum extrusion molded product integrally including a first guide rail 107 for moving and guiding the first runner body 105 and a second guide rail 108 for moving and guiding the second runner body 106. An auxiliary machine groove 109 is provided between the guide rails 107 and 108. On the front and rear surfaces of the fixed rail unit 103, a horizontal groove V-shaped thinning groove 110 is formed. As shown in FIG. 24, the movable rail unit 104 is formed by cutting a rail material having the same structure as that of the fixed rail unit 103 into a predetermined length, and the rear side of the movable rail unit 104 is a third guide that guides the first runner body 105 as a transition guide. It becomes the rail 111, and the front side becomes the fourth guide rail 112 for guiding the transition of the second runner body 106. Each of the first guide rail 107 and the second guide rail 108 is formed in a C-shaped cross section in a state of opening downward, and is formed in a state in which the rail wall is opposed to the front and rear at the lower end of the inner surface. Similar rail walls are formed on the third guide rail 111 and the fourth guide rail 112 so as to face each other in the front-rear direction.

  As shown in FIG. 25, the first runner body 105 is unitized with a transition frame 115 that is long to the left and right and four open / close runners 116 that are rotatably supported by the frame 115. The transition frame 115 is made of a plastic molded product having a U-shaped cross section, and seats 117 protrude from the lower portions of the front and rear surfaces at the left and right ends. Of the four seats 117, the front end of the seat 117 formed on the front surface on the open end side projects forward from the front surface of the first door 2, and this projecting portion is a lock piece (locked body) 80. Function as. The lock piece 80 is locked and held by a lock body 71 of a slide lock mechanism described later in a state where the first door 2 is fully opened. Engaging grooves 118 for engaging an upper mounting shaft 125 described later are formed at both left and right ends of the transition frame 115.

  The open / close runner 116 is configured by rotatably supporting a pair of front and rear rollers 119 disposed on the upper portion of the transition frame 115 by a roller shaft penetrating the transition frame 115 forward and backward. Of the four open / close runners 116, three open / close runners 116 are disposed at both ends of the transition frame 115 and in the center of the left and right, and the remaining open / close runner 116 is disposed at the closed end side indicated by an arrow. And the open / close runner 116 disposed at the center of the left and right. As described above, the three open / close runners 116 are arranged at the half position on the closed end side of the transition frame 115 because the first runner body 105 moves between the first guide rail 107 and the third guide rail 111. In this case, the first runner body 105 is smoothly transferred between the adjacent guide rails 107 and 111 so that two or more open / close runners 116 are always supported by one of the rails 107 and 111. Because.

  Since the 2nd runner body 106 is fundamentally the same structure as the 1st runner body 105, the same numerals are attached to the same member and the explanation is omitted. However, of the four seats 117, the front end of the seat 117 formed on the front surface on the closed end side projects forward from the front surface of the second door 3, and this projecting portion is a passive piece of the swing lock mechanism. It functions as a release piece (release tool) 37 for switching 64. Also in the second runner body 106, as in the first runner body 105, three open / close runners 116 are arranged at a half position on the closed end side of the transition frame 115. Accordingly, when the second runner body 106 moves between the second guide rail 108 and the fourth guide rail 112, the two or more open / close runners 116 are always supported by one of the rails 108 and 112. The second runner body 106 can be smoothly transferred between the adjacent guide rails 108 and 112.

  In order to fix the first runner body 105 to the first door 2, as shown in FIGS. 26 and 27, a pair of left and right upper holders 123 are embedded and fixed near the open end and the closed end of the upper surface of the first door 2. The upper runner base 124 is detachably attached to the holder 123. The upper holder 123 and the upper runner base 124 are both commercially available products, and the upper runner base 124 is integrated with the upper runner base 124 by inserting the upper runner base 124 into the upper holder 123 from the outside. Can be fixed to. The upper runner base 124 is provided with an upper mounting shaft 125 protruding above the upper surface of the first door 2, and the upper mounting shaft 126 is adjusted by adjusting the height adjusting screw 126 provided in the upper runner base 124. The height of the first door 2 can be adjusted by adjusting the vertical position of 125. Most of the embedding holes for the upper holder 123 formed on the closed end side are covered with a shielding cover 127. The upper runner base 124 is provided with a release lever 128. The lever 128 is tilted in a direction away from the upper holder 123 to release the locked state, and the upper runner base 124 can be detached from the upper holder 123. .

  Similarly, as shown in FIG. 28, a pair of left and right upper holders 123 are embedded and fixed to the open end and the closed end of the upper surface of the second door 3, and the upper runner base 124 is detachably attached to the holder 123. doing. Since the upper holder 123 and the upper runner base 124 are the same commercial products as the upper holder 123 and the upper runner base 124 mounted on the first door 2, the description thereof is omitted.

  When fixing the first runner body 105 to the first door 2, the left and right upper holders 123 are fixed to the first door 2, and then the upper runner base 124 is attached to one of the upper holders 123. In this state, the engaging groove 118 provided in the transition frame 115 is engaged with the upper mounting shaft 125 so that the inner back end of the engaging groove 118 is in close contact with the upper mounting shaft 125, and the other upper runner base 124 is moved upward. The holder 123 is mounted and the upper mounting shaft 125 is engaged with the other engaging groove 118 of the transition frame 115. Thus, in the state where the first runner body 105 is fixed to the first door 2, the first runner body 105 is sandwiched and held by the pair of left and right upper mounting shafts 125, so that the first runner body 105 cannot be moved left and right. Can be fixedly held. Furthermore, since the upper end surface of the engagement groove 118 is received by a flange portion provided at the upper end of the upper mounting shaft 125, the first runner body 105 is not separated from the first door 2. Similarly, the second runner body 106 can be fixed to the second door 3.

  In order to open / close the second door 3 in conjunction with the opening / closing operation of the first door 2, an opening / closing interlocking structure is provided between the first door 2, the second door 3 and the swing door 4. As shown in FIG. 29, the open / close interlock structure includes a pair of left and right pulley holders 130 provided at the lower corner of the second door 3, and a sliding guide frame (guide frame body) 131 that couples both pulley holders 130. ing.

  One ends of the connecting tools 135 and 136 are fixed to the straight transition portions of the wires 134, and the other end sides of the connecting tools 135 and 136 are connected to the first door 2 and the swing door 4. As shown in FIG. 30, the sliding guide frame 131 is configured by fixing rail frames 137 and 138 having a C-shaped cross section in a back-to-back manner, and the sliders 139 and 140 are slid by the rail frames 137 and 138, respectively. I am guiding you. A mounting groove 141 for assembling the opening / closing interlocking structure is formed on the lower surface of the second door 3 so as to open downward. At the left and right ends of the mounting groove 141, a holder groove 142 for the pulley holder 130 having a groove depth larger than the mounting groove 141 is formed.

  The pulley holder 130 is formed of a rectangular case body. A screw hole for inserting the screw 143 is formed in the upper portion of the pulley holder 130, and a pulley recess 145 having a tunnel cross-sectional shape for receiving the pulley 132 is recessed below the screw hole. It is formed. The left and right pulley holders 130 are made of the same parts, and fastening seats 146 for connecting the sliding guide frames 131 are provided on the opposing edges of both holders 130. By attaching both ends of the sliding guide frame 131 to both fastening seats 146 and fastening them with bolts 147, the pulley holder 130 and the sliding guide frame 131 can be integrated into a unit part.

  The opening / closing interlock structure formed as a unit part is assembled to the mounting groove 141 from below, and is fixed to the second door 3 by fixing the left and right pulley holders 130 with screws 143. The rotation planes of the two pulleys 132 in this state are vertical, and the pair of linear transition portions of the wire 134 are positioned above and below the mounting groove 141. As described above, when the opening / closing interlocking structure is disposed on the lower inner surface of the second door 3 with the rotation planes of the pulleys 132 being vertical, the opening / closing interlocking structure is disposed between the lower surface of the second door 3 and the floor surface. Compared with the case where it does, the clearance gap between the lower surface of the 2nd door 3 and a floor surface can be made small. Further, the open / close interlocking structure can be prevented from being exposed outside the second door 3, and the appearance of the double-acting type open / close door can be made simple and clean. Furthermore, foreign matter can be removed between the wire 134 and the pulley 132. It is possible to prevent the open / close interlock function from being damaged.

  As shown in FIG. 30, the connection tool 135 for the first door 2 is formed of a press fitting integrally provided with a horizontal arm portion 150 and a vertical connection wall 151, and a wire 134 is provided on the lower end side of the connection wall 151. A connection piece 152 for connection is fixed. The connection piece 152 is made of a plastic molded product, and is formed with two engagement recesses 153 opening downward on the lower surface side thereof. By engaging the short-axis end fitting 154 fixed to the lower straight transition portion of the wire 134 with the engagement recess 153, the connector 135 is moved along with the lower straight transition portion. be able to. Further, a slider 139 on the rear side is fixed to the connecting wall 151. Therefore, when the connecting tool 135 moves along with the wire 134, the slider 139 follows the connecting tool 135 and slides back and forth. As described above, when the connecting tool 135 is guided and supported by the sliding guide frame 131 via the slider 139, the reciprocating sliding operation of the connecting tool 135 can be performed smoothly.

  The connecting member 136 for the swing door 4 is formed of a press fitting integrally provided with a horizontal arm portion 156 and a vertical connecting wall 157, similarly to the previous connecting member 135, and a wire 134 is attached to the upper end of the connecting wall 157. A connection piece 158 for connecting the two is fixed. The connection piece 158 is made of the same component as the previous connection piece 152, and is fixed to the connection wall 157 with the engagement recess 159 opening upward. By engaging the short metal end fitting 160 fixed to the upper straight transition portion of the wire 134 with the previous engagement recess 159, the connector 136 can be moved along with the upper straight transition portion. . Thus, since the coupling tool 136 for the swing door 4 is connected to the upper straight transition portion via the end fitting 160, the vertical length of the vertical coupling wall 157 is equal to the coupling tool for the first door 2. It is set larger than the vertical length of 135 connecting walls 151. The connecting wall 157 is fixed to the slider 140. Therefore, when the connecting tool 136 moves along with the wire 134, the slider 140 moves back and forth along with the connecting tool 136. The function of the slider 140 is the same as the function of the slider 139 described above.

  In order to fix the connector 135 to the lower part of the first door 2, a lower holder 163 is embedded and fixed in the lower corner of the open end side of the first door 2 as shown in FIG. 164 is detachably mounted. The lower holder 163 and the lower runner base 164 are the same commercial products as the upper holder 123 and the upper runner base 124 described above, and they are integrated by inserting the lower runner base 164 into the lower holder 163 from the outside. Thus, the lower runner base 164 can be fixed to the first door 2. The lower runner base 164 is provided with a lower mounting shaft 165 protruding downward from the lower surface of the first door 2, a release lever 166, and the like. The lower runner base 164 is assembled to the rear side of the second door 3 by connecting the lower mounting shaft 165 to the arm portion 150 of the connector 135 in advance.

  Similarly, a lower holder 163 is embedded and fixed in the lower corner of the swing door 4 on the swing tip side, and a lower runner base 164 is detachably mounted on the holder 163 (see FIG. 23). Since the lower holder 163 and the lower runner base 164 are the same commercial products as the lower holder 163 and the lower runner base 164 attached to the first door 2, the description thereof is omitted. The lower runner base 164 is assembled to the front side of the second door 3 by connecting the lower mounting shaft 165 to the arm portion 156 of the connector 136 in advance.

  Each door 2, 3, 4 is assembled to the opening frame 1 in the following procedure. First, the swing door 4 is assembled to the opening frame 1 via the hinge 5. Next, the second door 3 is hung on the fourth guide rail 112 of the movable rail 104, the position of the coupling tool 136 is adjusted, and the second door 3 is inserted into and attached to the lower holder 163 of the swing door 4. And the open / close interlocking structure are connected via a coupler 136. Further, the first door 2 is hung on the third guide rail 111 of the movable rail 104, the position of the coupling tool 135 is adjusted, and the first door 2 is inserted into the lower holder 163 of the first door 2 to be attached. The opening / closing interlocking structure is connected via a coupler 135.

  As described above, when the first door 2, the second door 3 and the swing door 4 are connected to each other via the opening / closing interlocking structure in a restrained state, the opening / closing interlocking structure functions as a swing prevention structure. The lower portions of the first and second doors 2 and 3 can be restricted from swinging in the front-rear direction. Therefore, there is no need to provide a separate anti-rest structure, and the opening and closing of the first door 2 and the second door 3 can always be performed in a stable state. Further, since the second door 3 can be opened / closed in conjunction with the opening / closing operation of the first door 2, the opening / closing operation of the second door 3 is started in the final stage of the opening / closing stroke of the first door 2. Thus, the doors 2 and 3 can be smoothly opened and closed. The opening / closing movement amount of the second door 3 is half of the opening / closing movement amount of the first door 2, and the doors 2, 3 are simultaneously switched to the fully closed state or the fully opened state at the end of the opening / closing stroke. Further, since the first door 2, the second door 3, and the swing door 4 are connected to each other via an opening / closing interlock structure, the movement of the second door 3 toward the closed end in the fully closed state is interlocked with opening / closing. Since it can be restricted by the structure, it is not necessary to provide a separate structure for restricting movement, and the structure of the double-acting door can be simplified and the cost can be reduced accordingly.

  In order to smoothly open and close the first door 2 and the second door 3, the swing door 4 is swung between the swing tip (free end) of the swing door 4 and the upper frame 1 c of the opening frame 1. A rocking lock mechanism is provided to lock and hold the immobility. In addition, a slide lock mechanism for restricting the opening operation of the first door 2 is provided in the accessory groove 109 near the swinging base end of the movable rail unit 104 so that the three doors 2, 3, 4 are swung open. The first door 2 and the second door 3 are restricted from sliding toward the closed position. Further, a catch structure is provided on the third guide rail 111 so that the first door 2 opened to the open position can be held in the open position. In the state where the swing door 4 is closed, it is necessary to support the total weight of the first door 2 and the second door 3 by the swing door 4, but in order to reduce the weight burden acting on the swing door 4 A door support 194 is provided in the interior of the door recess 7 so that the movable rail unit 104 can be supported by the door support 194.

  24 and 31, the swing lock mechanism includes a case 60 embedded in the rear surface of the swing front end (free end) of the swing door 4 and a flat plate-like swing supported by the case 60 so as to be vertically slidable. The movement preventing body 61, a pair of left and right urging springs 62 that push up and urge the swing preventing body 61 upward, and a fixed engaging body 63 embedded in the upper frame 1c corresponding to the swing preventing body 61, etc. Configure. A triangular passive piece 64 projecting rearward of the case 60 is integrally provided on the rear surface of the rocking prevention body 61, and the release piece 37 provided on the seat portion 117 of the second runner body 106. Thus, the swing prevention body 61 can be switched to the unlocking posture by performing a push-down operation while resisting the biasing force of the biasing spring 62.

  The rocking block 61 is guided by a guide pin 66 fixed to the case 60 with a vertical slide groove 65 provided on the plate surface, and further, the passive piece 64 is slid and guided by a guide window 67 opened in the case 60. Therefore, only vertical sliding is supported. The passive piece 64 is formed with a slope cam 64a, and the release tool 37 is formed with an operation surface 37a having the same inclination angle as that of the slope cam 64a. The fixed engagement body 63 is formed with an engagement groove 63 a that allows the rocking prevention body 61 to enter and exit in a vertically penetrating manner.

  When the swing door 4 is in the closed position, the swing preventing body 61 is pushed up by the urging spring 62 as shown in FIG. 31, and its upper end engages with the engaging groove 63a of the fixed engaging body 63. doing. Therefore, even if an external force in the direction of swinging outward is applied to any of the three doors 2, 3, and 4, the swinging door 4 does not swing open and can maintain a closed posture. it can. Therefore, the first door 2 and the second door 3 can be smoothly opened and closed. In the state where the first door 2 and the second door 3 are opened to the open position, the release tool 37 rides on the slope cam 64a of the passive piece 64 and attaches the passive piece 64 as shown in FIG. The push-down operation is performed while resisting the biasing force of the spring 62. As a result, the engagement state between the swing prevention body 61 and the engagement groove 63a of the fixed engagement body 63 is released, and the restraint state of the swing door 4 can be released. As described above, the swing lock mechanism is automatically unlocked by the release tool 37 provided on the second door 3 in a state where the first door 2 and the second door 3 are opened to the open position.

  In FIG. 32, the slide lock mechanism includes a housing 70 that is inserted into and engaged with the auxiliary machine groove 109 and fixed by a bolt 169, and a horizontally long lock that is supported by the housing 70 so as to swing up and down via a support shaft 170.

The housing 70 is made of a plastic molded product, and an operation section 74 for housing the lock body 71 and a spring section 75 for housing a part of the detection body 72 and the detection spring 73 are formed on the front side thereof. Lock member 71 is vertical width of the support shaft 170 side is small, vertical width as they approach the swinging tip is from a large pair of front and rear plate-shaped die-cast molding, closing of the lock piece (the lock member) 80 at its distal end A lock surface 171 is provided to prevent movement in the direction. Cam grooves 86 described later are formed on the front and rear plate walls of the lock body 71 so as to be inclined downward toward the support shaft 170 side.

  The detection body 72 is made of a plastic molded product in which a spring receiving piece 83 protrudes from an upper part of a horizontal L-shaped slide shaft (shaft portion) 82, and includes an operation arm 175 on the retreat end side of the shaft portion 82. . Slide grooves 176 are formed in the front and rear walls of the spring section 75, and the entire detection body 72 is formed by the housing 70 by guiding a pair of left and right slide pins 177 fixed to the upper portion of the shaft portion 82 with the slide grooves 176. It is supported so that it can slide left and right. The detection spring 73 is composed of a compression spring, and moves and urges the detection body 72 in a direction in which the advance end 85 of the slide shaft 82 advances from the housing 70. As shown in FIG. 32 (a), the detecting body 72 when the swing door 4 is in the closed posture has its advancing end 85 received by the vertical frame 1b on the open end side, and the slide shaft 82 is Retreating toward the housing 70 against the biasing force of the detection spring 73. Further, as shown in FIG. 32 (b), when the swing door 4 is in the open posture, the slide shaft 82 is advanced toward the outside of the housing 70 by the detection spring 73. Thus, even when the slide shaft 82 is advanced, the end of the operating arm 175 is held between the front and rear plate walls of the lock body 71.

  A cam structure is provided between the detection body 72 and the lock body 71 in order to switch the lock body 71 by using the above-described withdrawal operation of the detection body 72. The cam structure is composed of an oblique cam groove 86 provided on the front and rear walls of the lock body 71 and an operation pin 87 fixed to the end of the operation arm 175 of the detection body 72. The operation pin 87 can be slid left and right along with the detection body 72, and the cam body 86 is operated during the operation to move the lock body 71 up and down.

  When the detection body 72 is retreated to the housing 70 against the detection spring 73, the operation pin 87 is located at the lower end of the cam groove 86, so that the lock body 71 is switched to the upper unlocking posture. (See FIG. 32 (a)). When the detection body 72 is advanced to the outside of the housing 70 by the detection spring 73, the operation pin 87 is positioned at the upper end of the cam groove 86 as shown in FIG. Descends to the lower face of the switch and switches to the locked position. Therefore, after the lock body 71 is switched to the locked position, the first door 2 does not move to the closed position side, and the first door 2 and the second door 3 are swung along with the swing door 4. It can be opened. Thus, the slide lock mechanism is automatically switched to the unlocked state in conjunction with the opening of the swing door 4 and can lock and hold the lock piece 80 provided on the first door 2.

  The lock body 71 in the above-mentioned slide lock mechanism is not switched to the locked posture until the swing door 4 is slightly opened. Therefore, when the swing door 4 is swingably opened, the first and second doors 2 and 3 may slide out due to the inertial force before the lock body 71 captures the lock piece 80. is there. In order to eliminate such problems, a catch structure is provided on the open end side of the third guide rail 111. As shown in FIG. 27, the catch structure is formed by integrating a base 180 fixed to the inner surface of the upper wall of the third guide rail 111 and a partial arc-shaped catch arm 181 extending in a cantilever manner from the base 180. It consists of a plastic molded product. A catch recess 182 is formed on the upper surface of the transition frame 115 of the first runner body 105 so as to correspond to the catch arm 181.

  When opening and closing the first door 2 and the second door 3, the first runner body 105 moves between the first guide rail 107 and the third guide rail 111, and similarly, the second runner body 106 is moved to the second guide rail. Transfer between 108 and the fourth guide rail 112. In order to perform the transfer between the rails more smoothly, the transfer between the rails is assisted at the adjacent ends of the guide rails 107, 108, 111, and 112, that is, the adjacent ends of the fixed rail unit 103 and the movable rail unit 104. A transfer guide body 185 is provided.

  As shown in FIGS. 33 to 35, the transfer guide body 185 protrudes from a guide port 186 similar to the rail cross section of each of the guide rails 107, 108, 111, and 112, and a mounting base end side of the guide port 186. The three mounting pieces 187 and a pair of front and rear fastening pieces 188 are integrally formed of a plastic molded product. In the guide port 186, a guide wall 189 that guides the first runner body 105 and the second runner body 106 toward the center of the guide rails 107, 108, 111, and 112 to be transferred is inclined toward the rail inner surface. It is provided in a C shape. The transfer guide body 185 is mounted by inserting three attachment pieces 187 into the auxiliary grooves 190 provided in the front and rear of each rail unit 103 and 104 and the auxiliary machine groove 109 in the front and rear center, and two fastening pieces 188 are attached to each.

  Next, the operation of each member when opening and closing the double-acting door will be described. As shown in FIG. 36 (a), when the first door 2, the second door 3, and the swing door 4 are in the closed state, the first door 2 is connected to the first guide via the first runner body 105. It is suspended by a rail 107. The second door 3 is suspended mainly by the second guide rail 108 via the second runner body 106, and the open / close runner 116 located at the open end is suspended by the fourth guide rail 112. In this state, when the handle 6 is grasped and the first door 2 is opened, the first door 2 and the second door 3 are simultaneously slid open as shown in FIG. The opening / closing amount of the second door 3 at this time is half of the opening / closing amount of the first door 2 as described above, but the movement rate of each door 2 and 3 is always the same.・ 3 reaches the open end at the same time.

  Immediately before the second door 3 reaches the open position, the first runner body 105 is completely transferred from the first guide rail 107 to the third guide rail 111, and the second runner body 106 is moved from the second guide rail 108 to the second guide rail 108. 4 Transfer to the guide rail 112. In this state, the catch recess 182 provided in the transition frame 115 of the first runner body 105 is engaged and captured by the catch arm 181. Further, the rocking prevention body 61 of the rocking lock structure is pushed down by the release tool 37 provided on the transition frame 115 of the second runner body 106 and switched to the unlocking posture. As shown in FIG. 36 (c), by opening the swing door 4 with the swing lock structure unlocked, the entire opening frame 1 can be swing open. The detection body 72 is advanced outward from the housing 70, and the slide lock mechanism is switched to the locked state as described above.

  When the swinging and swinging door 4 is returned to the closed position, the detection body 72 is again received by the vertical frame 1b on the open end side and retreated into the housing 70, so that the slide lock mechanism is locked. It is switched to the release posture. When the first door 2 is closed by grasping the handle 6 in this state, the catch recess 182 first separates from the catch arm 181 while elastically deforming the catch arm 181. Soon after the second door 3 moves along with the first door 2 and closes, the release tool 37 is separated from the slope cam 64a of the passive piece 64, so that the swing preventing body 61 is pushed up by the biasing spring 62. Thus, the fixed engagement body 63 is engaged to restrict the swing of the swing door 4.

  When the first door 2 is continuously closed, the first door 2 and the second door 3 move in the closing direction as shown in FIG. 36B, and the first runner body 105 is moved to the third guide rail. The second runner body 106 is transferred from the fourth guide rail 112 to the second guide rail 108. Finally, as shown in FIG. 36A, the entire opening surrounded by the opening frame 1 can be closed and closed by the first door 2, the second door 3, and the swing door 4. In the second door 3 in this state, since the first door 2 and the swing door 4 are connected via the opening / closing interlocking structure, the second door 3 can be restricted from moving further to the closing side.

  As described above, according to the three-door opening / closing door composed of the first door 2, the second door 3, and the swing door 4, the first door 2 and the second door 3 are opened as shown in FIG. The effective opening width B <b> 2 in the state where it is opened to the position exceeds a half value of the total opening width B <b> 1 of the opening frame 1. Specifically, the effective opening width B2 when the total opening width B1 is 100 is 54. Compared with the conventional two-door opening / closing door, when the total opening width B1 of the opening frame 1 is 1135 mm, the effective opening width is 618.5 mm, which is simple without the swinging door 4 being swung open. You can go in and out. Further, when the swing door 4 is opened and swinged while seated in a wheelchair, the swing door 4 is opened while approaching each of the doors 2 to 4 whose swing radius is smaller than that of the conventional open / close door. Therefore, the opening / closing operation of the door can be performed more easily and easily.

  As shown in FIG. 24, the door support 194 is formed in a rectangular block shape, and a support protrusion 195 that engages with the thinning groove 110 of the third guide rail 111 is formed in a rib shape on the front surface thereof. . The support protrusion 195 engages with the thinning groove 110 when the swing door 4 is in the closed position, and restricts the swing tip of the swing door 4 from tilting to the floor surface side.

( Example 4 ) FIGS. 37 and 38 show a double-acting open / close door according to Example 4 in which a swing lock mechanism is provided on the first door 2. FIG. In the double-acting open / close door of the third embodiment described above, the first runner body 105 is completely transferred to the third guide rail 111 in a state where the first door 2 and the second door 3 are opened to the open position. Further, the second runner body 106 is transferred to the fourth guide rail 112. However, as shown in FIG. 36C, the closed end side of the first door 2 is located on the lower surface side of the first guide rail 107. Utilizing this fact, a second swing lock mechanism is provided between the first door 2 and the first guide rail 107, and the first door 2, the second door 3, and the swing door 4 opened to the open position. Can be held in a locked state so as not to swing open. This rocking lock mechanism may be used in combination with the first rocking lock mechanism described in the third embodiment , or may be used alone.

  As described above, when the swing lock mechanism is provided between the first door 2 and the first guide rail 107, when the doors 2, 3, and 4 are swing-released, the unlocked lock mechanism is the second lock mechanism. It is necessary to pass through the lower surface of the guide rail 108.
