In position. For the main door wheels 21A and 21B moving from the closed end position toward the open end position, the end inclined surfaces 67A and 67A are inclined upward.

  The intermediate rolling surfaces 69 and 69 of the guide rails 61 and 62 are kept higher than the upper edge portion 41 of the riding rail 40 from the end bent vertices 68A and 68A on the closed end side toward the open end side. The level of the rolling surfaces 66, 66 and the upper edge 41 of the riding rail 40 is reversed at a position close to the end bending vertices 68B, 68B on the open end side of the intermediate rolling surfaces 69, 69. Then, the upper edge 41 of the riding rail 40 is higher than the rolling surfaces 66 and 66 up to the open ends of the guide rails 61 and 62.

  In FIG. 20, the slide door 12 is moved from the open end position P5 toward the closed end position P1 (closed operation) while being guided by the first and second guide rails 61 and 62 in the “closed guide inclined posture”. ) Is shown as a skeleton model.

  As shown in FIG. 20, in the closed guide inclined posture, the end bent vertices 68 </ b> B and 68 </ b> B on the open end side of the guide rails 61 and 62 are the second and fourth mountain-shaped protrusions 422 on the riding rail 40. , 424 is higher than the apex of the open end side, and the tip end portions of the open end side inclined surfaces 68B, 68B are lower than the open end side inclined surfaces 42B, 42B in the second and fourth chevron projections 422, 424. In position. And the end inclined surfaces 67B and 67B are climbingly inclined for the main door wheels 21A and 21B moving from the open end position toward the closed end position.

  The intermediate rolling surfaces 69 and 69 of the respective guide rails 61 and 62 are kept higher than the upper edge 41 of the riding rail 40 from the end bent vertices 68B and 68B on the open end side toward the closed end. The heights of the rolling surfaces 66 and 66 and the upper edge 41 of the riding rail 40 are reversed at positions close to the end bending vertices 68A and 68A on the closed end side of the intermediate rolling surfaces 69 and 69. Then, the upper edge portion 41 of the riding rail 40 is higher than the rolling surfaces 66 and 66 up to the end portions on the closing side of the guide rails 61 and 62.

  The above is description regarding the structure of the door guide apparatus 11 and the slide door apparatus 10 of this embodiment, and operation | movement is demonstrated below. As shown in FIGS. 3B and 15A, when the slide door 12 is positioned at the closed end position, the cam slider 50 is positioned at the closed end position within the range in which linear movement is possible. And the 2nd guide rails 61 and 62 are hold | maintained in an "open guide inclination attitude | position" as shown in FIG.16 and FIG.18 (A). Further, as shown in FIG. 19, at the closed end position P <b> 1, the riding door cars 22 </ b> A and 22 </ b> B of the door hangers 20 </ b> A and 20 </ b> B are closed ends of the first and third mountain-shaped protrusions 421 and 423. Riding on the side inclined surfaces 42A, 42A, the main door wheels 21A, 21B are lifted from the first and second guide rails 61, 62 (see FIG. 5). Since the closed end side inclined surfaces 42A and 42A on which the passenger doors 22A and 22B ride are respectively lowered toward the closed end side, the closed front end edge 13 of the slide door 12 is in contact with the closed side stopper wall 92. The end position P1 is held immovably, and the sliding door 12 can be prevented from opening without permission (moving from the closed end position P1). The closed end side inclined surfaces 42A and 42A of the first and third mountain-shaped protrusions 421 and 423 on which the passenger doors 22A and 22B ride are equivalent to the “door wheel holding inclined surface” of the present invention. Further, the closed end-side inclined surface 42A of the first mountain-shaped protrusion 421 corresponds to the “closed-end inclined surface for the riding door on the closed end side” in the present invention, and the closed end of the third angle-shaped protruding portion 423. The side inclined surface 42 </ b> A corresponds to “the door-holding inclined surface for the riding end door on the open end side”.

  When the sliding door 12 is opened to open the doorway 91 closed by the sliding door 12, the door handle 15 is gripped and the sliding door 12 is moved from the closed end position P1 to the “automatic opening operation start position P2.” Operate to move to. Immediately after the start of the movement, the first and third mountain-shaped protrusions 421 in which the riding door pulleys 22A and 22B are inclined while the main door pulleys 21A and 21B are lifted from the first and second guide rails 61 and 62, respectively. , 423 roll on the closed end side inclined surfaces 42A, 42A, and on the way, the main door wheel 21A, 21B rides on the end inclined surfaces 67A, 67A of the first and second guide rails 61, 62, Riding door cars 22 </ b> A and 22 </ b> B are lifted from the upper edge 41 of the riding rail 40. Then, when the main door pulleys 21A and 21B climb up the end inclined surfaces 67A and 67A that are inclined upward and reach the end bent vertices 68A and 68A near the closed end, the slide door 12 is automatically opened. It becomes. When the automatic opening operation start position P2 is reached, the holding by the closed end side inclined surfaces 42A and 42A with respect to the sliding door 12 at the closed end position P1 is released, and as shown in FIG. 18A, an intermediate rolling surface 69 is obtained. 69, the main door wheels 21A and 21B roll on their own, and the slide door 12 automatically slides toward the open end position P5. Here, when the main door carts 21A and 21B roll on the intermediate rolling surfaces 69 and 69 of the first and second guide rails 61 and 62, the riding door carts 22A and 22B It is in a state of being lifted from the upper edge portion 41 (see FIGS. 6 and 7).

  When the slide door 12 automatically moves toward the open end position P5 and reaches the “open end side transfer position P3” near the open end position P5 as shown in FIG. And the second guide rails 61 and 62 are transferred to the riding rail 40. Specifically, at the portions where the heights of the rolling surfaces 66, 66 of the guide rails 61, 62 and the upper edge portion 41 of the riding rail 40 are reversed, the riding door wheels 22A, 22B are second and fourth chevron shapes. The main door pulleys 21A and 21B are lifted from the intermediate rolling surfaces 69 and 69 of the first and second guide rails 61 and 62 while riding on the closed end side inclined surfaces 42A and 42A of the protrusions 422 and 424. At this time, the closed end side inclined surfaces 42A and 42A in the second and fourth mountain-shaped protrusions 422 and 424 are inclined upward for the passenger doors 22A and 22B toward the open end position P5, but the intermediate rolling surface 69 , 69 using the inertial force (kinetic energy) generated by descending the slope, the climbing door cars 22A, 22B climb up the closed end side inclined surfaces 42A, 42A. Immediately after the passenger doors 22A and 22B get over the apexes of the second and fourth mountain-shaped protrusions 422 and 424, the door rear edge 14 of the slide door 12 comes into contact with the opening-side stopper wall 93. As shown in FIGS. 4B and 15B, the slide door 12 is in the “open end position”. Here, the moving speed of the sliding door 12 can be decelerated (brake applied) by climbing the closed end side inclined surfaces 42A and 42A in which the riding door pulleys 22A and 22B are climbed and inclined. It is possible to prevent the door rear end edge 14 from violently colliding with the opening-side stopper wall 93 and to prevent the limbs from being pinched. Further, at the open end position P5, the riding door carts 22A and 22B are in a state of riding on the open end side inclined surfaces 42B and 42B in the second and fourth mountain-shaped protrusions 422 and 424, respectively, and the main door cart 21A, 21B is in a state of being lifted from the first and second guide rails 61 and 62.

  Further, as shown in FIG. 19, when the slide door 12 reaches the “open end side posture change position P4” between the “open end side transfer position P3” and the “open end position P5”, the state shown in FIG. As shown, the pressing projection wall 29 provided on the open end door hanger 20 </ b> B contacts the open end door contact fitting 53 </ b> B of the cam slider 50. Then, the cam slider 50 moves together with the slide door 12 to the open end side within the range in which the slide door 12 can move linearly from the “open end position change position P4” to the “open end position P5”. When the slide door 12 reaches the open end position P5, the cam slider 50 also reaches the open end position as shown in FIGS. 12C and 15B, and the “open end side posture change position P4” in FIG. As shown in the change to the “open end position P5”, the postures of the first and second guide rails 61 and 62 are changed from the “open guide inclined posture” to the “closed guide inclined posture”.

  Here, as shown in FIG. 19, when the sliding door 12 is at the open end position P5, the open end side inclined surface 42B in each of the second and fourth mountain-shaped protrusions 422 and 424 on which the passenger doors 22A and 22B ride. 42B are inclined downward toward the open end side, so that when the slide door 12 reaches the open end position P5 and the door rear end edge 14 collides with the open side stopper wall 93, it slides by reaction. It is possible to prevent the door 12 from moving backward (moving toward the closed end). Further, the end inclined surfaces 67B and 67B on the open end side of the first and second guide rails 61 and 62 are inclined upward for the main door wheel 21A and 21B moving from the open end position P5 toward the closed end position P1. Therefore, the sliding door 12 can be reliably prohibited from moving to the closed end side without permission.

  Further, the riding door carts 22A and 22B ride on the upper edge portion 41 (second and fourth mountain-shaped protrusions 422 and 424) of the riding rail 40, so that the main door carts 21A and 21B are in the first and second guides. The first and second guide rails 61 and 62 are lifted from the rails 61 and 62 and the first and second guide rails 61 and 62 are not subjected to the weight of the slide door 12 (from the open end side transfer position P3 to the open end position P5). Since the second guide rails 61 and 62 are changed from the “open guide inclined posture” to the “closed guide inclined posture”, the posture change of each guide rail 61 and 62 can be performed smoothly.

  The above-described opening operation of the slide door 12 is summarized as follows. When the slide door 12 positioned at the “closed end position P1” moves toward the “open end position P5”, the slide door 12 is moved to the “automatic opening operation start position P2”, “open end side” as shown in FIG. It reaches “open end position P5” via “transfer position P3” and “open end position change position P4”. When the sliding door 12 is moved from the “closed end position P1” to at least the “automatic opening start position P2”, the holding of the “closed end position P1” with respect to the slide door 12 is released and the slide door 12 is “automatically opened”. Generated by descending the rolling surfaces 66 and 66 of the first and second guide rails 61 and 62 and descending the rolling surfaces 66 and 66 from the “operation start position P2” to the “open end position P5”. It moves automatically by the inertia force.

  Further, during the period from the “closed end position P1” to the “open end position change position P4”, the slide door 12 is positioned at the closed end position within the range in which the cam slider 50 can move linearly. The guide rails 61 and 62 are held in the “open guide inclined posture”, and the cam slider 50 is moved between the “open end position change position P4” and the “open end position P5”. The first and second guide rails 61 and 62 are switched from the “open guide inclined posture” to the “closed guide inclined posture” by moving from the closed end position to the open end position within the range in which the linear movement is possible. . That is, the attitude of the guide rails 61 and 62 for the next closing operation can be changed using the inertial force of the sliding door 12 that is automatically opening.

  As shown in FIGS. 4B and 15B, when the slide door 12 is located at the open end position, the cam slider 50 is located at the open end position within the range in which the slide door 12 can move linearly. And the 2nd guide rails 61 and 62 are hold | maintained in a "closed guide inclination attitude | position" as shown in FIG.17 and FIG.18 (B). Further, as shown in FIG. 20, at the open end position P5, the riding door cars 22A and 22B of the door hangers 20A and 20B are opened at the second and fourth mountain-shaped protrusions 422 and 424 of the riding rail 40. Riding on the end-side inclined surfaces 42B, 42B, the main door carts 21A, 21B are in a state of being lifted from the first and second guide rails 61, 62. Since the open end side inclined surfaces 42B and 42B of the second and fourth mountain-shaped protrusions 422 and 424 on which the riding door pulleys 22A and 22B ride are respectively lowered toward the open end side, the door of the slide door 12 The rear end edge 14 is held immovably at the open end position P5 in contact with the open side stopper wall 93, and the sliding door 12 can be prevented from being closed arbitrarily (moving from the open end position P5). Here, the open end side inclined surfaces 42B and 42B in the second and fourth mountain-shaped protrusions 422 and 424 on which the riding door pulleys 22A and 22B are mounted correspond to the “door wheel holding inclined surfaces” of the present invention. Further, the open end side inclined surface 42B of the second chevron protrusion 422 corresponds to the “closed end tilting surface for the riding door on the closed end side” of the present invention, and the open end of the fourth chevron protrusion 424. The side inclined surface 42 </ b> B corresponds to “the door-holding inclined surface for the riding end door on the open end side” of the present invention.

  When closing the doorway 91, the door handle 15 is grasped and the sliding door 12 is operated so as to move from the open end position P5 shown in FIG. 20 to the automatic closing operation start position P6. Immediately after the start of the movement, the second and fourth mountain-shaped protrusions 422 in which the riding door pulleys 22A and 22B are inclined while the main door pulleys 21A and 21B are lifted from the first and second guide rails 61 and 62, respectively. , 424 rolls on the open end side inclined surfaces 42B, 42B, and the main door wheel 21A, 21B rides on the end inclined surfaces 67B, 67B of the first and second guide rails 61, 62 on the way, Upper door pulleys 22 </ b> A and 22 </ b> B are lifted from the upper edge 41 of the riding rail 40. When the main door pulleys 21A and 21B climb up the end inclined surfaces 67B and 67B that are inclined to reach the end bent vertices 68B and 68B closer to the open end, the slide door 12 is in the automatic closing operation start position P6. It becomes. When the automatic closing operation start position P6 is reached, the holding of the open end side inclined surfaces 42B and 42B with respect to the sliding door 12 at the open end position P5 is released and, as shown in FIG. 69, the main door wheels 21A and 21B roll on their own, and the slide door 12 automatically slides toward the closed end position P1. Here, when the main door carts 21A and 21B roll on the intermediate rolling surfaces 69 and 69 of the first and second guide rails 61 and 62, the riding door carts 22A and 22B It is held in a state of being lifted from the upper edge portion 41.

  When the slide door 12 automatically moves toward the closed end position P1 and reaches the “closed end side transfer position P7” close to the closed end position P1, as shown in FIG. And the second guide rails 61 and 62 are transferred to the riding rail 40. Specifically, at the portion where the heights of the rolling surfaces 66 and 66 of the guide rails 61 and 62 and the upper edge portion 41 of the riding rail 40 are reversed, the riding door cars 22A and 22B are the first of the riding rails 40. Riding on the open end side inclined surfaces 42B and 42B of the first and third mountain-shaped protrusions 421 and 423, the main door wheels 21A and 21B are intermediate rolling surfaces 69 and 69 of the first and second guide rails 61 and 62, respectively. From the surface. At this time, the open end side inclined surfaces 42B and 42B in the first and third mountain-shaped protrusions 421 and 423 are inclined upward for the passenger doors 22A and 22B toward the closed end position P1, but are intermediate rolling surfaces. Using the inertial force (kinetic energy) generated by descending the slopes 69 and 69, the passenger doors 22A and 22B climb up the open end side inclined surfaces 42B and 42B. Then, immediately after the riding door pulleys 22A and 22B get over the tops of the first and third mountain-shaped protrusions 421 and 423, the door front edge 13 of the sliding door 12 abuts against the closing-side stopper wall 92, As shown in FIGS. 3B and 15A, the slide door 12 is in the “closed end position”. Here, the moving speed of the sliding door 12 can be decelerated (brake applied) by climbing the open end side inclined surfaces 42B and 42B where the riding door pulleys 22A and 22B are climbing and inclined. It is possible to prevent the front edge 13 of the door from colliding violently with the blocking-side stopper wall 92 and to prevent the limb from being pinched. Further, as shown in FIG. 20, when the closed end position P1, the riding door pulleys 22A and 22B are in a state of riding on the closed end side inclined surfaces 42A and 42A in the first and third mountain-shaped protrusions 421 and 423, respectively. Thus, the main door carts 21A and 21B are lifted from the first and second guide rails 61 and 62.

  Further, as shown in FIG. 20, when the slide door 12 reaches a “closed end side posture change position P8” between the “closed end side transfer position P7” and the “closed end position P1”, the state shown in FIG. As shown, the pressing projection wall 29 provided on the closed end door hanger 20 </ b> A contacts the closed end door contact fitting 53 </ b> A of the cam slider 50. Then, the cam slider 50 moves together with the slide door 12 to the closed end side in the range in which the slide door 12 can move linearly from the “closed end side transfer position P7” to the “closed end position P1”. When the slide door 12 reaches the closed end position P1, as shown in FIGS. 13C and 15A, the cam slider 50 also reaches the open end position, and the “closed end side posture change position P8” in FIG. As shown in the change to the closed end position P1, the first and second guide rails 61 and 62 are changed in posture from the “closed guide inclined posture” to the “open guide inclined posture”.

  Here, as shown in FIG. 20, when the slide door 12 is at the closed end position P1, the closed end side inclined surface 42A in each of the first and third mountain-shaped protrusions 421 and 423 on which the passenger doors 22A and 22B ride. , 42A are inclined downward toward the closed end side, so that when the slide door 12 reaches the closed end position P1 and the door front end edge 13 collides with the closed side stopper wall 92, the slide door is rebounded. It is possible to prevent the 12 from moving backward (moving toward the open end side). Further, the end inclined surfaces 67A, 67A on the closed end side of the first and second guide rails 61, 62 are inclined upward for the main door wheel 21A, 21B moving from the closed end position P1 toward the open end position P5. Therefore, the sliding door 12 can be reliably prohibited from moving to the open end side without permission.

  Further, the riding door carts 22A and 22B ride on the upper edge 41 (first and third mountain-shaped protrusions 421 and 423) of the riding rail 40, so that the main door carts 21A and 21B are in the first and second positions. The first and second guide rails 61 and 62 are lifted from the guide rails 61 and 62 and the weight of the sliding door 12 is not applied to the first and second guide rails 61 and 62 (from the closed end side transfer position P7 to the closed end position P1). Since the second guide rails 61 and 62 are changed from the “closed guide inclined posture” to the “open guide inclined posture”, the posture can be changed smoothly.

  The closing operation of the slide door 12 described above is summarized as follows. When the slide door 12 located at the “open end position P5” moves toward the “closed end position P1”, the slide door 12 moves to the “automatic closing operation start position P6”, “closed end side” as shown in FIG. It reaches the “closed end position P1” via the “transfer position P7” and the “closed end side posture change position P8”. When the sliding door 12 is moved from the “open end position P5” to at least the “automatic closing operation start position P6”, the holding of the slide door 12 with respect to the “open end position P5” is released and the slide door 12 is “automatically closed”. Generated by descending the rolling surfaces 66 and 66 of the first and second guide rails 61 and 62 and descending the rolling surfaces 66 and 66 from the operation start position P6 to the closed end position P1. It moves automatically with the inertia force.

  Further, during the period from the “open end position P5” to the “closed end side posture change position P8”, the slide door 12 is positioned at the open end position within the range in which the cam slider 50 can move linearly. The guide rails 61 and 62 are held in the “closed guide inclined posture”, and the cam slider 50 is moved between the “closed end side posture change position P8” and the “closed end position P1”. The first and second guide rails 61 and 62 are switched from the “closed guide inclined posture” to the “open guide inclined posture” by moving from the open end position to the closed end position within the range in which the linear movement is possible. . That is, the posture of the guide rails 61 and 62 for the next opening operation can be changed using the inertial force of the slide door 12 that is automatically closing.

  Thus, according to the present embodiment, the first and second guide rails 61 and 62 correspond to the first and second main door carts 21A and 21B arranged at both ends of the upper end portion of the slide door 12, respectively. Are provided separately, and the first and second guide rails 61 and 62 are supported so as to be tiltable about a central portion in the longitudinal direction. As a result, the guide rails 61 and 62 are linked to each other to switch between an open guide inclined posture in which the open end side is lowered and a closed guide inclined posture in which both the closed end sides are lowered. Both the automatic opening operation and the automatic closing operation using the inclination of 62 can be performed.

  Specifically, when the sliding door 12 is opened, the moving operation is performed from the closed end position P1 to the automatic opening operation start position P2 near the closed end position P1. Then, the slide door 12 automatically moves from the automatic opening operation start position P2 to the open end position P5. When the sliding door 12 is closed, the sliding door 12 is moved from the open end position P5 to the automatic closing operation start position P6 near the open end position P5. Then, the slide door 12 automatically moves from the automatic closing operation start position P6 to the closed end position P1.

  That is, in order to cause the sliding door 12 to perform both the automatic opening operation and the automatic closing operation, the sliding door 12 is slightly slid toward the other end at both ends (closed end position and open end position) of the range in which the sliding door 12 can slide. It is sufficient to perform the opening operation and the closing operation, and it is no longer difficult to perform either the opening operation or the closing operation as in the prior art. That is, according to the present invention, both the opening operation and the closing operation of the slide door 12 can be easily performed by using the inclination of the both guide rails 61 and 62. Moreover, the first and second guide rails 61 and 62 always have a contact point of the first main door 21A on the first guide rail 61 and a contact point of the second main door 21B on the second guide rail 62. Since they are interlocked so as to have the same height, the slide door 12 itself does not tilt even if both the guide rails 61 and 62 are tilted to the closed side or the open side.

  When the slide door 12 reaches the open end position P5 and the closed end position P1, the slide door 12 is held immovable by the closed end side inclined surface 42A and the open end side inclined surface 42B of the riding rail 40. Therefore, after the operation for opening the slide door 12 is performed, the slide door 12 is not arbitrarily closed, and conversely, after the operation for closing the slide door 12 is performed, the slide door 12 is not arbitrarily opened.

  In addition, the slide door 12, which is automatically closing, presses the cam slider 50 to one side at the closed end position change position P8 near the closed end position P1, and the first and second guide rails 61 and 62 are moved. The slide door 12 that automatically changes the posture from the closed guide tilt posture to the open guide tilt posture, and the slide door 12 that is automatically opening opens the posture change member 50 at the open end side posture change position P4 near the open end position P5. The first and second guide rails 61 and 62 are automatically changed from the open guide inclined posture to the closed guide inclined posture, so that both guide rails 61 and 62 are closed to the open guide inclined posture. Since the posture is changed between the inclined guide posture, no special operation is required and the operability is excellent. In the present invention, the posture of the guide rails 61 and 62 for the next opening or closing operation can be changed using the inertia force of the sliding door 12 that is automatically closing or opening. . That is, the kinetic energy of the sliding door 12 that is slid by using the potential energy due to the inclination of the guide rails 61, 62 can be recovered by changing the posture of the guide rails 61, 62, which is excellent in energy efficiency. Accordingly, the operation force in the opening / closing operation of the slide door 12 can be suppressed. In addition, when the sliding door 12 is opened and closed electrically by using an electric drive source such as a motor or a solenoid, a slight range in the slidable range (the closed end position P1 and the automatic opening operation start position P2). And only the movement between the open end position P5 and the automatic closing operation start position P6 is required to be motorized, so that the capacity of the power source can be suppressed.

  Furthermore, according to the present invention, the first and second guide rails are lifted from the first and second guide rails 61 and 62 so that the main doors 21A and 21B are lifted so that the weight of the slide door 12 is not applied. Since the postures 61 and 62 are changed between the closed guide inclined posture and the open guide inclined posture, the posture can be changed smoothly.

  Moreover, the open end side inclined surfaces 42B and 42B for holding the slide door 12 at the open end position P5 and the closed end side inclined surfaces 42A and 42A for holding the slide door 12 at the closed end position P1 are all provided. Since it is formed on the common riding rail 40, the relative positional accuracy between the inclined surfaces 42A and 42B is easier than when the inclined surfaces 42A and 42B are divided into separate parts. Can be high.

[Second Embodiment]

It can be attached to any position where it can be easily operated (for example, in the vicinity of the entrance / exit 91 of the wall 90). The lever-type handle 72 can be rotated within a predetermined rotation range with the horizontal axis as the center of rotation. When the lever-type handle 72 is released from the lever-type handle 72 after the rotation operation, the lever-type handle 72 is rotated by a torsion spring (not shown). It is configured to automatically return to one end position (position shown in FIG. 22) of the movable range.

  One end of a wire 73 as an “operation force transmitting member” of the present invention is connected to the lever-type handle 72. A wire connecting member 74 is fixed to the other end of the wire 73, and two branch wires 73 </ b> A and 73 </ b> B extend from the wire connecting member 74. These two branch wires 73A and 73B are respectively connected to a pair of pressing and rotating levers 80A and 80B described below. When the lever-type handle 72 is turned to the other end side of the rotatable range, the wire 73 is pulled toward the lever-type handle 72, and the pair of pressing and turning levers 80A and 80B are symmetrical as will be described later.

  Here, one of the two branch wires 73A and 73B and the wire 73 are connected to one, and the wire connected to the one and the other of the two branch wires 73A and 73B are connected to the cylinder. By inserting into the wire connecting member 74 having a shape structure and crushing (caulking) the wire connecting member 74, the two short and long wires are connected. The wire connecting member 74 and the two branch wires 73A and 73B correspond to the “pressing connection mechanism” of the present invention, and the wire connecting member 74 corresponds to the “input movable portion” of the present invention.

  As shown in FIG. 23, the pair of pressing and rotating levers 80A and 80B are pivotally supported by the mounting bracket 75 so as to be rotatable. The mounting bracket 75 is disposed at the center upper position in the longitudinal direction of the rail assembly 30 (see FIG. 26), and the ceiling plate portion 753 is provided between the upper edge portions of the fixed plate portion 751 and the lever support plate portion 752 facing each other in the horizontal direction. The structure contacted by is made. As shown in FIG. 24, the fixed plate portion 751 is fixed to the wall body 90, and the ceiling plate portion 753 is disposed above the moving area of each door hanger 20A, 20B, and the lever support plate portion 752 is provided. Are arranged on the side farther from the wall body 90 than the upper protruding wall 26 in each door hanger 20A, 20B. Further, as shown in FIG. 23, the lever support plate portion 752 projects to the open end side and the closed end side in the sliding direction of the slide door 12, and the pressing and turning levers 80A and 80B are symmetrical in the projecting portions. Is attached to.

  Each of the pressing and rotating levers 80A and 80B has a fan-like plate shape and is symmetrical to each other. A wire through hole 81 is formed through the apex portion of each of the pressing and rotating levers 80A and 80B, and a ring portion formed by folding back the ends of the branch wires 73A and 73B is passed therethrough.

  Each pressing rotation lever 80A, 80B is overlapped on the surface of the lever support plate portion 752 facing the wall 90 side and is rotatably supported. That is, a support shaft hole (not shown) is formed through the press rotation lever 80A, 80B in the vicinity of the wire through hole 81, and the support hole is formed from the lever support plate portion 752 into the wall body. A lever rotation support shaft 76 that protrudes horizontally on the 90 side is fitted. Each of the pressing and rotating levers 80A and 80B can rotate in a vertical plane parallel to the lever supporting plate portion 752 around the lever rotating support shaft 76. The lever rotation support shaft 76 and the rotation axes (rail rotation support shaft 36) of the first and second guide rails 61 and 62 are parallel to each other.

  A pressing leg 83 protrudes from an arcuate outer edge of the pressing rotation levers 80A and 80B opposite to the apex. The pressing leg 83 protrudes from the ends on the sides close to each other among the arc-shaped outer edge portions. Further, the pressing leg portion 83 protrudes in a direction opposite to the wire through hole 81 with the lever rotation support shaft 76 interposed therebetween (see FIG. 25B).

  As shown in FIG. 23, on the ceiling plate portion 753 of the mounting bracket 75, pulleys 77 and 77 for guiding the branch wires 73A and 73B bifurcated from the wire connecting member 74 to the press rotation levers 80A and 80B, respectively. It is provided in pairs on the left and right. Each of the pulleys 77 and 77 is rotatable about an axis perpendicular to the ceiling plate portion 753, and the branch wires 73A and 73B are provided between the pulleys 77 and 77 and the pressing rotation levers 80A and 80B. And extends in a direction perpendicular to the lever rotation support shaft 76. A pulley 89 is also provided at an intermediate position between the lever-type handle 72 and the wire connecting member 74 in the wire 73 as necessary.

  Thus, when the lever-type handle 72 is rotated from one end position to the other end position of the rotatable range, the wire 73 is pulled toward the lever-type handle 72 and the branch wires 73A and 73B are in opposite directions ( Pulled by the pulleys 77 and 77 side), the pair of pressing rotation levers 80A and 80B rotate in the opposite directions (symmetrical) in conjunction with each other around the lever rotation support shaft 76. Specifically, as shown in FIG. 26A, from the closed leg position where the pressing legs 83, 83 of the pair of pressing rotation levers 80A, 80B can approach each other in the left-right direction to start the pressing operation. As shown in FIG. 5B, the pressing legs 83, 83 are rotated to the open leg position where they are separated from each other in the left-right direction.

  Here, in FIG. 30, the rotation areas RA and RB of the pressing legs 83 and 83 (hatched areas in the figure) of the pair of pressing and rotating levers 80A and 80B are the door pressure receiving pins 24A and 24B. The linear motion areas SA and SB are shown. Hereinafter, of the pair of pressing rotation levers 80A and 80B, the pressing rotation lever 80A (corresponding to the “closed pressing reciprocating member” of the present invention) disposed on the closed end side is referred to as “closed pressing rotation lever 80A”. When the pressing rotation lever 80B (corresponding to the “open pressing reciprocating member” of the present invention) disposed on the open end side is referred to as “open pressing rotation lever 80B”, the closed pressing rotation lever 80A is provided. The rotation area RA of the pressing leg 83 is partially overlapped with the area on the open end SA2 side in the linear movement area SA of the door pressure receiving pin 24A on the closed end side. Further, the rotation region RB of the pressing leg 83 provided in the open pressing rotation lever 80B is so that a portion thereof overlaps the region on the closed end SB1 side in the linear motion region SB of the door pressure receiving pin 24B on the open end side. It has become.

The configuration of the present embodiment is as described above. Next, the operation of the present embodiment will be described.
As shown in FIG. 26A, in the state where the slide door 12 is located at the closed end position, the door pressure receiving pin 24B is in contact with the pressing leg portion 83 of the opening pressing rotation lever 80B, and a pair of pressing rotations are performed. The moving levers 80A and 80B are in the closed leg position. At this time, the door pressure pins 24A and 24B on the open end side and the closed end side are both positioned at the closed ends SA1 and SB1 of the linear motion areas SA and SB, and only the door pressure pin 24B on the open end side is opened and pressed. It will be in the state arrange | positioned in the rotation area | region RB of the rotation lever 80B (refer FIG. 30).

  In this state, when the lever-type handle 72 of the remote operation device 70 is rotated from one end position to the other end position of the rotatable range, the change from FIG. 26 (A) to FIG. 26 (B) is shown. In addition, the pair of pressing rotation levers 80A and 80B rotate symmetrically to the open leg position. At this time, only the door pressure receiving pin 24B on the open end side located in the rotation region RB of the open pressing rotation lever 80B is pressed by the pressing leg 83 provided in the opening pressing rotation lever 80B. With this pressing force, the slide door 12 moves from the closed end position P1 to the automatic opening operation start position P2 (see FIG. 19).

  When the hand is released from the lever-type handle 72, the lever-type handle 72 automatically returns to one end position of the rotatable range, and the pair of pressing and turning levers 80A and 80B are closed as shown in FIG. The position is returned to an intermediate position between the position and the open leg position.

  The slide door 12 moved to the automatic opening operation start position P2 by the pressing force of the opening pressing rotation lever 80B is moved to the opening end position P5 by the inclination of the first and second guide rails 61 and 62 in the opening guide inclination posture. Move automatically toward. As shown in FIG. 27 (A), when the slide door 12 is close to the open end, the door pressure receiving pin 24A on the closed end side presses the closing press rotation lever 80A waiting in front of the slide direction (opening operation direction). It abuts on the leg 83. Further, as shown in the change to FIG. 5B, the pressing leg portion 83 of the closing pressing rotation lever 80A is pushed by the door pressure receiving pin 24A until the sliding door 12 reaches the open end position P5. When the slide door 12 reaches the open end position P5, the pressing and rotating levers 80A and 80B are returned to the closed leg position. When the slide door 12 is at the open end position P5, the door pressure pins 24A and 24B on the open end side and the closed end side are both located at the open ends SA2 and SB2 of the linear motion areas SA and SB, and are on the closed end side. Only the door pressure receiving pin 24A is disposed in the rotation area RA of the closing pressing rotation lever 80A (see FIG. 30).

  In this state, when the lever-type handle 72 is rotated from one end position to the other end position of the rotatable range in the same manner as in the opening operation, the change from FIG. 28 (A) to FIG. 28 (B). As shown, the pair of pressing rotation levers 80A and 80B rotate symmetrically to the open leg position. At this time, only the door pressure pin 24A on the closed end side located in the rotation area RA of the closed pressing rotation lever 80A is pressed by the pressing leg 83 provided in the closing pressing rotation lever 80A. With this pressing force, the slide door 12 moves from the open end position P5 to the automatic closing operation start position P6 (see FIG. 20).

  When the hand is released from the lever-type handle 72, the lever-type handle 72 automatically returns to one end position of the rotatable range, and the pair of pressing and turning levers 80A and 80B are closed by their own weights as shown in FIG. The position is returned to an intermediate position between the position and the open leg position.

  The slide door 12 moved to the automatic closing operation start position P6 by the pressing force of the closing pressing rotation lever 80A is moved to the closed end position P1 by the inclination of the first and second guide rails 61 and 62 in the closed guide inclination posture. Move automatically toward. As shown in FIG. 29 (A), when the slide door 12 is close to the closed end, the door pressure pin 24B on the open end side presses the open press rotation lever 80B waiting in front of the slide direction (closing operation direction). It abuts on the leg 83. Further, as shown in the change to FIG. 5B, the pressing leg portion 83 of the opening pressing rotation lever 80B is pushed by the door pressure receiving pin 24B until the sliding door 12 reaches the closed end position P1. When the slide door 12 reaches the closed end position P1, the pressing and rotating levers 80A and 80B are returned to the closed leg position.

  Here, the pressing and rotating levers 80A and 80B are returned from the open leg position to the closed leg position by their own weight and the pressing force received from the sliding door 12 during automatic operation. The pressing force of the door 12 corresponds to the “initial position urging means” according to the present invention.

  According to the present embodiment, the same effects as those of the first embodiment can be obtained, and the following effects can be achieved. That is, when the sliding door 12 is closed / closed, it is possible to select either the door handle 15 fixed to the sliding door 12 or the remote control device 70, thereby improving convenience. Further, when the opening / closing operation is performed by the remote operation device 70, the sliding door 12 can be closed and the sliding door 12 can be closed by the same operation of the lever-type handle 72. In addition, the remote control device 70 can be arranged at an easily operable position away from the slide door 12. For example, it can be arranged at a position slightly away from the entrance 91 so that it can be easily operated while riding on a wheelchair, or can be arranged near the bed so that it can be easily operated while lying on the bed.

  Further, the door pressure pins 24A and 24B on the closed end side and the open end side are arranged so that their linear motion areas SA and SB are arranged on the same straight line and in the left-right symmetrical manner with a space therebetween. The rotation lever 80A and the opening and pressing rotation lever 80B can be arranged symmetrically and can be connected so as to operate symmetrically. This simplifies the structure and facilitates design.

  Further, since the pressing rotation levers 80A and 80B rotate about a horizontal axis orthogonal to the sliding direction of the slide door 12 and press the door pressure receiving pins 24A and 24B, the door pressure receiving pins 24A and 24B are configured. Compared to the case where the pressing is performed by the closed pressing reciprocating member and the open pressing reciprocating member that move directly, the support structure of the closed pressing rotating lever 80A and the opening pressing rotating lever 80B can be simplified.
