  The present invention relates to a first door panel provided in either one of a car or a level of a building that is movable along a hoistway in a building, and a second door panel provided in either the car or the level. The present invention relates to an elevator door engaging device and an elevator.

  Generally, as shown in FIG. 12 and FIG. 13, the elevator is either one of a car 100 provided so as to be movable along a hoistway in a building and a building hierarchy F (hereinafter simply referred to as a hierarchy F) ( In the figure, a first door panel 101 provided in the car 100: see FIG. 12) and a second door panel 102 provided in either the car 100 or the other side of the hierarchy F (in the figure, the hierarchy F: see FIG. 13). Prepare.

  The first door panel 101 and the second door panel 102 are provided so as to be movable in a lateral direction perpendicular to the vertical direction. As a result, the first door panel 101 is configured to change its position between an open position where the first opening provided in either the car 100 or the floor F is fully opened and a closed position where the first opening is closed. The two-door panel 102 is configured to change the position between an open position where the second opening provided in either the car 100 or the floor F is fully opened and a closed position where the second opening is closed.

  The elevator is a driving device 103 provided on either the car 100 or the floor F on the assumption that each of the first door panel 101 and the second door panel 102 is provided so as to be movable in the lateral direction. A driving device 103 that moves the door panel 101 between an open position and a closed position, and a second door lock device 104 that is directly or indirectly connected to the second door panel 102, the second door panel being in the closed position The second door lock device 104 that can be switched between a locked state in which the lateral movement of the 102 is restricted and an unlocked state in which the restriction of the lateral movement of the second door panel 102 is released, and the first door panel 101 directly A second or second door locking device 104 that can be switched between a locked state and an unlocked state. A door engaging device 105 configured to transmit a force on one side (hereinafter referred to as an opening direction) in the lateral direction and a force on the other side (hereinafter referred to as a closing direction) to the second door lock device 104 (for example, a patent) Reference 1).

  The driving device 103 applies a lateral force to the first door panel 101 to move the first door panel 101 in the lateral direction. The driving device 103 mechanically or electrically stops the first door panel 101 at each of the open position and the closed position.

  As shown in FIG. 14, the second door lock device 104 includes a base portion 106 that is directly or indirectly fixed to the second door panel 102, and a direction perpendicular to the vertical direction and the lateral direction (hereinafter referred to as the base portion 106). A lock arm 107 rotatably connected around an axis extending in the depth direction), and a pressure receiving portion 108 disposed on the rotation center of the lock arm 107 from either the car 100 or the floor F A pressure receiving portion 108 projecting toward one side, and an operating portion 109 fixed to the lock arm 107 at a position away from the rotation center of the lock arm 107, one from the other side of the car 100 or the level F And an operating portion 109 protruding toward the side.

  The lock arm 107 is an arm body 110 extending in a uniaxial direction, and has an arm body 110 having a distal end portion and a proximal end portion on the opposite side of the distal end portion in a uniaxial direction, and is connected to the distal end portion of the arm body 110. And a flange 111. The base end portion of the arm body 110 is coupled to the base portion 106 so as to be rotatable around an axis extending in the depth direction. The flange 111 is formed so as to be able to be locked to the receiving member Ra fixed in the vicinity of the second opening in the other of the car 100 and the floor F. The flange 111 generally protrudes in a direction perpendicular to the direction in which the arm body 110 extends, and has a locking surface that can face the receiving member Ra in the lateral direction (opening direction of the second door panel 102).

  Each of the pressure receiving unit 108 and the operating unit 109 is configured by, for example, a roller that is rotatable around an axis extending in the depth direction. In other words, the pressure receiving unit 108 is configured by a roller that can rotate concentrically with the rotation center of the lock arm 107, and the operation unit 109 is configured by a roller that can rotate at a position shifted from the rotation center of the lock arm 107. The operation unit 109 is disposed closer to the closing direction of the second door panel 102 in the lateral direction than the pressure receiving unit 108.

  In the second door lock device 104, the locking surface of the lock 111 of the lock arm 107 is received when the second door panel 102 closes the second opening and no force in the opening direction is applied to the operating portion 109. Opposite the member Ra. Thereby, the 2nd door lock apparatus 104 controls the movement of the opening direction of the 2nd door panel 102 connected with self. Further, in the second door lock device 104, the lock arm 107 is rotated by the force in the opening direction acting on the operating portion 109, so that the locking surface at the flange 111 of the lock arm 107 does not face the receiving member Ra. Become. Thereby, the 2nd door lock apparatus 104 accept | permits the horizontal movement of the 2nd door panel 102 connected with self.

  As shown in FIG. 15, the door engaging device 105 includes a pair of vanes 112 arranged in a horizontal direction orthogonal to the vertical direction, and a pair of vanes 112 provided with a changeable horizontal distance, and a pair of vanes. 112 and a rotating arm 113 for changing the horizontal interval of 112.

  The rotary arm 113 includes an intermediate support portion 113a that is rotatably supported by one vane 112 of the pair of vanes 112, and a first arm portion 113b that extends from the intermediate support portion 113a. A first arm portion 113b having an abutting portion 114 capable of abutting against a striker S fixed to either one of 100 and level F, and a second arm portion 113c extending from the intermediate support portion 113a, The portion side includes a second arm portion 113c operatively connected to the other vane 112 of the pair of vanes 112.

  In the door engaging device 105 configured as described above, the contact portion 114 of the rotary arm 113 is pushed by the striker S in a state where the first door panel 101 is in the closed position. Thereby, the front-end | tip part of the rotation arm 113 (2nd arm part 113c) pushes the other vane 112 (vane 112 in the opening direction side of the 1st door panel 101), and maximizes the space | interval of a pair of vane 112. That is, as shown in FIG. 16, the rotary arm 113 has the second door lock device 104 (the pressure receiving portion 108 and the operating portion 109 in the vertical direction between the pair of vanes 112 with the first door panel 101 in the closed position. ) Is allowed to enter.

  Then, when the first door panel 101 in the closed position starts to move in the opening direction, the door engaging device 105 configured as described above moves together with the first door panel 101 as shown in FIG. 17 and moves a predetermined distance D1 in the lateral direction. To do. Meanwhile, one vane 112 (the vane 112 on the closing direction side of the first door panel 101) pushes the operating portion 109 of the second door lock device 104 and rotates the lock arm 107 to engage the flange 111 with the receiving member Ra. Release the stop. Further, when the first door panel 101 moves in the opening direction, the lateral distance between the fixing position of the door engaging device 105 and the fixing position of the striker S increases, so that the rotating arm 113 rotates in one direction, and the rotating arm 113 is rotated. The tip of the (second arm portion 113c) brings the other vane 112 closer to the one vane 112.

  When the first door panel 101 is further moved in the opening direction and the door engaging device 105 is moved by a predetermined distance D2 in the lateral direction as shown in FIG. 18, the tip of the first arm portion 113b of the rotary arm 113 and the striker S are moved. The contact is released. Accordingly, the other vane 112 approaches one vane 112, and as a result, the pair of vanes 112 sandwich the pressure receiving unit 108. That is, the door engaging device 105 connected to the first door panel 101 is in the second state via the second door lock device 104 (pressure receiving portion 108) in a state where the locking of the flange portion 111 with respect to the receiving member Ra is released. A state in which a lateral force can be transmitted to the door panel 102 is established.

  Therefore, when the restriction of the movement of the second door panel 102 by the second door lock device 104 is released, the door engagement device 105 receives the drive of the drive device 103 and moves to the first door panel 101 that moves in the opening direction. 102 is moved and moved in the opening direction.

  Further, in the door engaging device 105 having the above-described configuration, the contact portion 114 of the rotating arm 113 is also the striker S when the first door panel 101 in the open position receives the drive of the driving device 103 and moves in the closing direction. The pair of vanes 112 sandwich the pressure receiving portion 108 until they come into contact with each other. That is, the door engaging device 105 connected to the first door panel 101 applies a lateral force to the second door panel 102 via the second door lock device 104 even when the first door panel 101 moves to the closed position. It becomes ready to communicate.

  Therefore, the door engagement device 105 releases the restriction of the movement of the second door panel 102 by the second door lock device 104, and the second door panel is moved to the first door panel 101 that moves in the closing direction under the driving of the driving device 103. 102 is moved and moved in the closing direction.

  When the first door panel 101 approaches the closed position, the contact portion 114 of the rotating arm 113 contacts the striker S, and the rotating arm 113 rotates in the other direction. Along with this, the tip of the rotary arm 113 (second arm portion 113 c) separates the other vane 112 from the one vane 112. In addition, when the first door panel 101 further approaches the closed position, the biasing of the second door lock device 104 by the one vane 112 to the operating portion 109 is weakened. Thereby, the lock arm 107 rotates and the collar part 111 is latched by the receiving member Ra (refer FIG. 16).

  Therefore, the door engaging device 105 causes the second door lock device 104 to restrict the lateral movement of the second door panel 102 while the first door panel 101 moves in the closing direction and reaches the closed position, and The two-door lock device 104 is allowed to move in the vertical direction (climbing the car 100).

  In this way, this type of elevator not only operates the two door panels 101 and 102 with one driving device 103 but also prevents the door panels 101 and 102 from being opened while the car 100 is raised and lowered. Ensuring safety.

JP 2013-103780 A

  By the way, as described above, the door engaging device 105 configured as described above moves in the opening direction together with the first door panel 101, thereby pushing the operating portion 109 with the other vane 112 to release the locked state of the second door locking device 104. To do. That is, as shown in FIG. 17, the door engaging device 105 configured as described above rotates the lock arm 107 while changing the distance between the pair of vanes 112 according to the movement of the first door panel 101 in the opening direction. (unlock). Therefore, the second door panel 102 can move in the lateral direction after the first door panel 101 has moved the predetermined distance D1.

  Therefore, in the door engaging device 105 configured as described above, the timing when the first door panel 101 starts moving when the first door panel 101 opens the first opening, and the second door panel 102 opens the second opening. There is a difference in timing when the second door panel 102 starts moving.

  Further, as shown in FIG. 18, the door engaging device 105 configured as described above moves in the closing direction together with the first door panel 101, and moves by a predetermined distance D2 immediately before the second door panel 102 reaches the closed position. The abutting portion 114 of the one arm portion 113b hits the striker S, and the other vane 112 is separated from the one vane 112 (the interval between the pair of vanes 112 is increased). In addition, after the second door panel 102 reaches the closed position, the door engaging device 105 configured as described above moves further by a predetermined distance D1 in the closing direction together with the first door panel 101, so that the operating portion by one vane 112 is operated. The urging | biasing with respect to 109 is weakened, and the 2nd door lock apparatus 104 is finally made into a locked state.

  Therefore, in the door engaging device 105 configured as described above, the stop timing of the first door panel 101 when the first door panel 101 closes the first opening, and the second door panel when the second door panel 102 closes the second opening. There is also a difference with the stop timing of 102.

  Thus, in the conventional door engaging apparatus 105, since the movement timing of the 1st door panel 101 and the 2nd door panel 102 has a difference (gap), there exists a possibility that the user using an elevator may feel uncomfortable.

  Then, this invention makes it a subject to provide the door engagement apparatus for elevators and an elevator which can open and close a door panel, without making a user feel uncomfortable.

  The elevator door engaging device according to the present invention is provided so as to be movable in a lateral direction perpendicular to the vertical direction on either a car or a level movable along a hoistway in a building having a level. A pair of vanes supported by the first door panel, wherein the pair of vanes are arranged in the horizontal direction and the interval in the horizontal direction is changeable, and the driving device is provided in either the car or the hierarchy. A control lever having a connecting portion connected to an output portion that moves in a lateral direction during driving, and at least a connecting portion is located on a closing direction side of the first door panel in accordance with the lateral movement of the output portion. And an operation lever configured to change the position to the second position on the opening direction side of the first door panel, and the connecting portion is moved from the second position to the first position in a state where the connecting portion is located at the second position. Restrict position change On the other hand, the operating lever includes a lock mechanism that allows the connecting portion to change position from the second position to the first position while the first door panel is in the closed position, and the operation lever moves the connecting portion from the second position to the first position. The second door lock device connected to a second door panel movably provided in a lateral direction on either the car or the floor by changing the position of the pair of vanes. The actuating portion that switches from a state where the second door panel is allowed to move laterally to a state where the second door panel is allowed to move laterally by being biased toward the opening direction of the second door panel. And a pressure receiving portion of the second door lock device, wherein the pressure receiving portion receiving the lateral force can be interposed between the pair of vanes in the vertical direction, while the connecting portion is changed from the first position to the second position. Repositioning Reduce the width of each pair of vanes, characterized in that it allows entrapment of a pair of vanes at least the pressure receiving portion of the actuating portion and the pressure receiving portion intervened between a pair of vanes.

  According to the said structure, when the connection part exists in the 1st position, it will be in the state which the space | interval of a pair of vane expanded, and when the cage | basket | car raises / lowers along a hoistway, it is the 2nd connected with the 2nd door panel. When the operation part and the pressure receiving part of the door lock device pass vertically between the pair of vanes and the car and the level of the building correspond to each other (the car stops at the level specified by the car), the second door lock The operating part and the pressure receiving part of the apparatus are arranged between the pair of vanes.

  And since the connecting part of the operating lever is connected to the output part of the driving device, when the output part of the driving device moves to one side in the lateral direction (opening direction of the first door panel) during driving, the connecting part of the operating lever Also, the position is changed from the first position toward the second position. Thereby, an operation lever narrows the space | interval of a pair of vane, and the action | operation part of the 2nd door lock apparatus between a pair of vanes is urged | biased by the vane by the horizontal direction. Accordingly, the second door lock device switches from a state in which the second door panel is restricted from moving in the lateral direction to a state in which the second door panel is allowed to move in the lateral direction. At this time, the drive device causes a lateral force to act on the connecting portion of the operation lever as the output portion moves, but the connecting portion changes position from the first position to the second position, so No lateral force is applied and the first door panel is maintained in the closed position.

  And when the connection part of an operation lever reaches a 2nd position, a pair of vane which narrowed the space | interval will pinch | interpose the pressure receiving part of a 2nd door lock apparatus. In this state, if the output unit of the drive device continues to move to one side in the lateral direction (the opening direction of the first door panel), the force directed to one side in the lateral direction (the force in the opening direction of the first door panel) is the second. Acts on the first door panel via a connecting part that maintains in position. In addition, since the pair of vanes sandwich the pressure receiving portion of the second door lock device connected to the second door panel, the force directed toward one side in the lateral direction (the opening direction of the first door panel) causes the second door lock device to It also acts on the second door panel. In this state, as described above, since the second door lock device allows the second door panel to move in the lateral direction, the first door panel and the second door panel start to move together in the opening direction. And if a drive device stops, since the force of a horizontal direction will not act with respect to a 1st door panel and a 2nd door panel, a 1st door panel and a 2nd door panel will stop together. Therefore, the first door panel and the second door panel are simultaneously fully opened and stopped.

  The locking device restricts the position of the connecting portion from being changed from the second position to the first position while the connecting portion is in the second position, so that the first door panel and the second door panel are fully opened. Even if the output part of the drive device starts to move to the other side in the lateral direction (the closing direction of the first door panel) from the state where the operation lever is connected, the connecting part of the operating lever does not change its position toward the first position. A force directed to the other side of the direction (the closing direction of the first door panel) acts on the connecting portion maintained at the second position. Thereby, a force directed to the other side in the lateral direction (the closing direction of the first door panel) acts on the first door panel via the operation lever (connecting portion). In addition, since the pair of vanes sandwich the pressure receiving portion of the second door lock device connected to the second door panel, the force directed toward the other side in the lateral direction (the closing direction of the first door panel) causes the second door lock device to It also acts on the second door panel.

  Thereby, the first door panel and the second door panel start to move together in the closing direction. When the driving device continues to drive and the first door panel and the second door panel reach the closed position (with the first door panel in the closed position), the locking device moves the connecting portion from the second position to the first position. Allow repositioning. Thereby, when the output part of the drive device tries to continue to move to the other side in the horizontal direction, the force directed to the other side in the horizontal direction (the closing direction of the first door panel) is not transmitted to the first door panel, The position of the connecting portion of the operation lever is changed from the second position to the first position. Accordingly, the operation lever widens the distance between the pair of vanes. Along with this, the sandwiching of the pair of vanes with respect to the pressure receiving portion of the second door lock device is released, and the biasing against the operating portion is released. As a result, the second door lock device restricts the movement of the second door panel in the lateral direction.

  And when the connection part of an operation lever reaches the 1st position, it will be in the state where the space | interval of a pair of vane expanded, and when the cage | basket | car raises / lowers along a hoistway, it is the 2nd door lock connected with the 2nd door panel. The operating part and the pressure receiving part of the device are in a state in which they can escape in the vertical direction from between the pair of vanes. Further, in this state, as described above, when the car is raised and lowered later, the operating portion and the pressure receiving portion of the second door lock device can pass (intervene) between the pair of vanes.

  As described above, the elevator door engaging device having the above-described configuration can link the start and stop of the first door panel and the second door panel, and thus can open and close the door panel without making the user feel uncomfortable. .

  As one aspect of the present invention, there are two or more link bodies arranged at intervals in the vertical direction, each having both end portions and an intermediate portion between the both end portions, and both end portions being a pair of vanes Two or more provided so as to be rotatable about an axis extending in the depth direction perpendicular to the vertical direction and the horizontal direction with respect to the axis, and the intermediate portion being rotatable about the axis extending in the depth direction. The operation lever is provided so as to be rotatable about an axis extending in the depth direction and is rotated forward and backward around the axis so as to change the position of the connecting portion between the first position and the second position. While being configured, as the connecting portion changes position from the first position to the second position, one end side is pressed rather than the intermediate portion of one of the two or more link bodies, while the connecting portion is 2nd position to 1st position It may include a pressing portion to release the pressing against one side of the middle portion of the link member with the position change.

  If it does in this way, two or more link bodies and a pair of vanes will constitute a parallel link. And the connection part of an operation lever follows the movement of the output part of a drive device, and a control lever rotates to the one side or the other side around an axis line by changing a position between the 1st position and the 2nd position. . When the connecting portion is changed from the first position to the second position and the operation lever rotates to one side around the axis, the pressing portion of the operation lever pushes the position away from the rotation center of one link body, and the link body Rotate. On the other hand, when the connecting portion is changed from the second position to the first position and the operating lever is rotated to the other side around the axis, the pressing portion of the operating lever is separated from the position away from the rotation center of one link body, The link body is allowed to rotate. As a result, the pair of vanes quickly widen the interval. Therefore, it is possible to reliably and satisfactorily perform urging and releasing the operation portion of the second door lock device by the pair of vanes and sandwiching and releasing the pressure receiving portion.

  In this case, the lock mechanism has a lock lever provided so as to be rotatable around an axis extending in the depth direction, and the lock lever is rotated around the axis so that the connecting portion is positioned at the second position. And a state in which the engagement with the operation lever with the connecting portion positioned at the second position is released. In this way, the lock lever rotates, and the engagement between the operation lever with the connecting portion positioned at the second position and the operation lever with the connection portion positioned at the second position is achieved. It is possible to switch to a state in which is canceled. Therefore, the control lever can be restricted and released without complicating the structure.

  In this case, the lock lever has a contact portion that can contact the striker fixed to either the car or the floor, and the contact portion as the first door panel moves in the closing direction. May be configured to release the engagement with the operation lever with the connecting portion positioned at the second position in a state where the striker contacts the striker and rotates around the axis, and the first door panel reaches the closed position. . If it does in this way, regulation of an operation lever can be canceled mechanically according to the arrangement state of the 1st door panel.

  As another aspect of the present invention, there may be provided urging means for urging the operation lever so as to change the position of the connecting portion from the second position toward the first position. In this way, since the urging force of the urging means is constantly acting on the operation lever, the connecting portion is reliably moved from the second position to the first position when the lock mechanism releases the restriction of the operation lever. Change the position to. In other words, the operation of the operation lever in a state where the restriction by the lock mechanism is released becomes good.

  As another aspect of the present invention, a first door lock device that restricts movement of the first door panel in the closed position in the opening direction is provided, and the first door lock device is directly or indirectly attached to the first door panel 3. And a first striker fixed to the vane movably provided in the lateral direction of the pair of vanes, and the lock arm has a distal end portion and a proximal end portion in a uniaxial direction. An arm main body, an arm main body that is supported directly or indirectly by the first door panel so that the base end portion can rotate around an axis extending in the depth direction, and a flange portion that is connected to the distal end portion of the arm main body. A hook that can be locked to the receiving member fixed to either the car or the floor, and a first abutting portion that is fixed at a position shifted from the center of rotation at the base end of the arm body, The first striker is the first In the opening direction of the first door panel with respect to the contact portion may be contactable with provided.

  In this way, when the output portion of the driving device moves in the opening direction of the first door panel in the state where the first door panel is in the closed position, the vane moves in the lateral direction as described above, and the distance between the pair of vanes Narrows. Accordingly, as the vane moves in the lateral direction (opening direction of the first door panel), the first striker fixed to the vane also moves in the lateral direction (opening direction of the first door panel). Along with this, the first striker comes into contact with the first contact portion. Since the first contact portion is fixed at a position shifted from the center of rotation at the base end portion of the arm body, the contact force of the first striker against the first contact portion causes the arm body to move to one side around the axis. Rotate. Thereby, the latch of the collar part with respect to a receiving member is cancelled | released, and the movement of the opening direction of a 1st door panel is accept | permitted. Therefore, the first door panel can be moved to the open position by continuously moving the output portion of the drive device in the opening direction of the first door panel. Moreover, when the output part of a drive device moves to the closing direction of a 1st door panel and a 1st door panel reaches | attains a closed position, as above-mentioned, a space | interval of a pair of vane will spread. Accordingly, as the vane moves in the lateral direction (the closing direction of the first door panel), the first striker fixed to the vane also moves in the lateral direction (the closing direction of the first door panel). Along with this, the first striker moves away from the first contact portion, and the force in the opening direction does not act on the first contact portion. As a result, the arm body is rotated to the other side around the axis, and the collar portion is locked to the receiving member.

  Therefore, when the first door panel is in the closed position, the hook portion of the lock arm supported directly or indirectly by the first door panel is locked to the receiving member fixed to either the car or the level. The This reliably restricts the first door panel in the closed position from being inadvertently moved in the opening direction.

  In this case, the first door lock device further includes a second striker fixed to a vane movably provided in the lateral direction, and the lock arm is fixed at a position shifted from the rotation center at the base end portion of the arm body. A second abutting portion disposed between the first abutting portion and the center of rotation of the arm body, wherein the second striker is disposed on the second abutting portion. The first door panel may be provided so as to be able to contact in the closing direction.

  In this way, when a force in the opening direction is applied to the first door panel in a state where the operation portion and the pressure receiving portion of the second door lock device are between the pair of vanes, the first door panel by the first door lock device Movement in the opening direction is allowed. Specifically, when the first door panel attempts to move in the lateral direction (opening direction), one vane (the vane on the closing direction side of the first door panel) of the pair of spaced vanes is the second door. It hits the operating part or pressure receiving part of the locking device. Accordingly, a lateral force acts on the vane, and the vane is urged toward the closing direction of the first door panel and tries to move in the same direction. Since the second striker is fixed to the vane movable in the lateral direction, the second striker moves in the closing direction of the first door panel together with the vane.

  The second contact portion is disposed at a position between the first contact portion and the rotation center of the arm body, and the second striker can contact the second contact portion in the closing direction of the first door panel. Therefore, when the second striker comes into contact with the second contact portion as the first door panel moves in the closing direction, the contact force of the second striker against the second contact portion causes the arm main body to move along the axis. Rotate around one side. Thereby, the latch of the collar part with respect to a receiving member is cancelled | released, and the movement of the opening direction of a 1st door panel is accept | permitted. Therefore, the first door panel can be opened only when the car corresponds to the building level and a power outage or disaster occurs (when the drive unit is in a state where it cannot be driven).

And a second contact portion 760d disposed at a position sandwiching the rotation center between the first contact portion 760c and the first arm body 760a.

  A base end portion of the first arm main body 760a is rotatably supported via a shaft 703 protruding from the second surface of the first base main body 700. Thereby, the first lock arm 760 rotates in one direction around the shaft 703 as a rotation center, so that the first arm body 760a overlaps the first receiving member R1 from above and the first receiving member. The state is switched to a state away from R1.

  The first flange portion 760b protrudes from the distal end portion of the first arm main body 760a in a direction (orthogonal direction) intersecting the direction (uniaxial direction) in which the first arm main body 760a extends. In the present embodiment, the first lock arm 760 is arranged such that the first arm body 760a extends in the lateral direction. On the basis of this, the first flange portion 760b protrudes downward from the first arm body 760a.

  The first collar portion 760b has a locking surface (not numbered) that can be opposed to the first receiving member R1 in the lateral direction. If it demonstrates concretely, 1st receiving member R1 fixed to the cage | basket | car 2 has the to-be-latched surface (not numbered) which faces the closing direction of the 1st door panel 3. As shown in FIG. Accordingly, the first flange portion 760b is a locking surface that can face the locked surface of the first receiving member R1, and has a locking surface that faces the opening direction of the first door panel 3. The first lock arm 760 is in a state where the first arm main body 760a overlaps the first receiving member R1 from above, so that the engaging surface of the first collar 760b and the first receiving member R1 are engaged. The stop surface opposes and is locked to the first receiving member R1, and the first arm body 760a is separated from the first receiving member R1 with the shaft 703 as the center of rotation. The locking surface is shifted from the locked surface of the first receiving member R1, and the locking by the first receiving member R1 is released. In the present embodiment, the first door lock device 76 includes urging means (spring) 763 that urges the first lock arm 760 to rotate in one direction. That is, the first door lock device 76 includes urging means 763 that urges the first lock arm 760 so that the engagement surface overlaps the locked surface.

  The first contact portion 760c is disposed at a position that is offset from the rotation center of the first arm main body 760a and that can face the first striker 761. That is, the first contact portion 760c is provided to rotate the first lock arm 760 (first arm body 760a) by the action of a lateral force.

  The second contact portion 760d is located at a position that is shifted from the rotation center of the first arm main body 760a and can face the second striker 762. That is, the second contact portion 760d is provided to rotate the first lock arm 760 (first arm body 760a) by the action of a lateral force.

  In the present embodiment, the first contact portion 760c and the second contact portion 760d are arranged with the rotation center of the first arm body 760a interposed therebetween. Each of the first contact portion 760c and the second contact portion 760d includes a cam follower that is rotatable about an axis that extends in the same direction as the rotation center of the first arm main body 760a.

  In the present embodiment, since the pair of vanes 71 are both provided to be movable in the lateral direction, the first striker 761 and the second striker 762 are one vane 71 on the closing direction side of the first door panel 3. Fixed to.

  The first striker 761 and the second striker 762 are fixed to the surface of the first piece 710 of one vane 71 facing the first base 70. The first striker 761 and the second striker 762 are arranged at intervals in the vertical direction. In the present embodiment, since the first contact portion 760c and the second contact portion 760d are arranged with the rotation center of the first arm body 760a interposed therebetween, the first striker 761 and the second striker 762 are also the first arm. It arrange | positions on both sides of the rotation center of the main body 760a.

  The first striker 761 is provided so as to be able to come into contact with the first contact portion 760c in the opening direction of the first door panel 3. The second striker 762 is provided so as to be able to come into contact with the second contact portion 760d in the closing direction of the first door panel 3. Accordingly, in the present embodiment, the first striker 761 and the second striker 762 are arranged so as to be shifted in the lateral direction.

  Specifically, the first striker 761 is arranged closer to the closing direction of the first door panel 3 than the rotation center of the first arm body 760a. Thus, the first striker 761 has a first contact surface 761a that can face or contact the first contact portion 760c and that faces the opening direction of the first door panel 3. . That is, the first striker 761 is configured to be able to bias the first contact portion 760c when the vane 71 moves in the opening direction of the first door panel 3.

  The second striker 762 is disposed on the opening direction side of the first door panel 3 with respect to the rotation center of the first arm main body 760a. Thereby, the second striker 762 is a second contact surface 762a that can face or contact the second contact portion 760d and has a second contact surface 762a that faces the closing direction of the first door panel 3. . That is, the second striker 762 is configured to be able to bias the second contact portion 760d when the vane 71 is pushed in the closing direction of the first door panel 3 and moves in the same direction. In other words, the first contact surface 761a of the first striker 761 and the second contact surface 762a of the second striker 762 are opposite to each other, but the first striker 761 and the second striker 762 have the first lock arm. Since the first striker 761 is urged by the first striker 761 and the second striker 762 is urged by the second striker 762, the first lock arm 760 is moved. It acts to rotate in one direction (same direction). This rotational direction coincides with the rotational direction of the first lock arm 760 that is unlocked from the state in which the first flange portion 760b is locked to the first receiving member R1.

  As described above, the door engaging device 7 according to the present embodiment is movable in the lateral direction perpendicular to the vertical direction to the car 2 that is movable in the vertical direction along the hoistway R in the building having the floor F. A pair of vanes 71 supported by the provided first door panel 3, the pair of vanes 71 arranged in the horizontal direction and having a changeable horizontal distance, and the driving device 5 provided in the car 2. The operation lever 72 has a connecting portion 720 that is connected to the output portion 53 that moves in the lateral direction when driven at the same time, and the connecting portion 720 moves in the closing direction of the first door panel 3 as the output portion 53 moves in the lateral direction. In the state where the operation lever 72 configured to change the position to the first position P1 on the side and the second position P2 on the opening direction side of the first door panel 3 and the connecting portion 720 are located at the second position P2. The connecting portion 720 is at the second position P. The lock mechanism 73 that restricts the position change from the second position P2 to the first position P1 while the first door panel 3 is in the closed position while restricting the position change from the first position P1 to the first position P1. With. And the operation lever 72 expands the space | interval of a pair of vane 71 by changing the position of the connection part 720 from the 2nd position P2 to the 1st position P1, and it is the 2nd door panel provided in the hierarchy F so that a movement in the horizontal direction was possible. 4 is an operation part 60 of the second door lock device 6 connected to the second door panel 4, and is urged toward the opening direction of the second door panel 4 to restrict the second door panel 4 from moving laterally. An operating part 60 that switches the second door panel 4 to a state in which the second door panel 4 is allowed to move in the lateral direction, and a pressure receiving part 61 that the second door lock device 6 has, the pressure receiving part 61 that receives a lateral force, Can be interposed between the pair of vanes 71 in the vertical direction. On the other hand, the operating lever 72 narrows the distance between the pair of vanes 71 by changing the position of the connecting portion 720 from the first position P1 to the second position P2, and the operating portion 60 and the pressure receiving force interposed between the pair of vanes 71. At least the pressure receiving portion 61 of the portion 61 can be sandwiched between the pair of vanes 71.

  As a result, as shown in FIG. 5, the gap between the pair of vanes 71 is widened with the connecting portion 720 in the first position P1, and when the car 2 moves up and down along the hoistway R, the first The operating part 60 and the pressure receiving part 61 of the second door lock device 6 connected to the two-door panel 4 pass between the pair of vanes 71 in the vertical direction, and the car 2 and the building floor F are in a corresponding position ( When the car 2 stops at the designated level F), the operating portion 60 and the pressure receiving portion 61 of the second door lock device 6 are disposed between the pair of vanes 71.

  Since the connecting portion 720 of the operating lever 72 is connected to the output portion 53 of the driving device 5, the output portion 53 of the driving device 5 moves to one side in the lateral direction (the opening direction of the first door panel 3) during driving. Then, as shown in FIG. 7, the position of the connecting portion 720 of the operation lever 72 is also changed from the first position P1 toward the second position P2. As a result, the operation lever 72 narrows the distance between the pair of vanes 71, and the operating portion 60 of the second door lock device 6 between the pair of vanes 71 is biased laterally by the vanes 71, as shown in FIG. 11. Is done. Accordingly, the second door lock device 6 switches from a state in which the second door panel 4 is restricted from moving in the horizontal direction to a state in which the second door panel 4 is allowed to move in the horizontal direction. At this time, the driving device 5 applies a lateral force to the connecting portion 720 of the operation lever 72 as the output portion 53 moves, but the connecting portion 720 changes the position from the first position P1 to the second position P2. Therefore, no lateral force acts on the first door panel 3, and the first door panel 3 is maintained in the closed position.

  Then, when the connecting portion 720 of the operation lever 72 reaches the second position P <b> 2, the pair of vanes 71 having a narrow interval sandwich the pressure receiving portion 61 of the second door lock device 6. In this state, if the output unit 53 of the driving device 5 continues to move to one side in the lateral direction (the opening direction of the first door panel 3), the force directed to one side in the lateral direction (the force in the opening direction of the first door panel 3). ) Acts on the first door panel 3 via the connecting portion 720 maintained at the second position P2. Further, since the pair of vanes 71 sandwich the pressure receiving portion 61 of the second door lock device 6 connected to the second door panel 4, the force directed toward one side in the lateral direction (the opening direction of the first door panel 3) is the first. It also acts on the second door panel 4 via the two-door lock device 6. In this state, as described above, since the second door lock device 6 allows the second door panel 4 to move in the lateral direction, the first door panel 3 and the second door panel 4 are moved together in the opening direction. Start moving. And if the drive device 5 stops, since the force of a horizontal direction will no longer act with respect to the 1st door panel 3 and the 2nd door panel 4, the 1st door panel 3 and the 2nd door panel 4 will stop together. Accordingly, the first door panel 3 and the second door panel 4 are simultaneously fully opened and stopped.

  The locking device restricts the position of the connecting portion 720 from being changed from the second position P2 to the first position P1 in a state where the connecting portion 720 is located at the second position P2. Even if the output portion 53 of the drive device 5 starts to move to the other side in the lateral direction (the closing direction of the first door panel 3) from the state where the door panel 4 is fully opened, the connecting portion 720 of the operation lever 72 is The position does not change toward the position P1, and the force directed toward the other side in the lateral direction (the closing direction of the first door panel 3) acts on the connecting portion 720 maintained at the second position P2. Thereby, a force directed to the other side in the lateral direction (the closing direction of the first door panel 3) acts on the first door panel 3 via the operation lever 72 (connecting portion 720). Further, since the pair of vanes 71 sandwich the pressure receiving portion 61 of the second door lock device 6 connected to the second door panel 4, the force directed toward the other side in the lateral direction (the closing direction of the first door panel 3) is the first. It also acts on the second door panel 4 via the two-door lock device 6.

  Thereby, the first door panel 3 and the second door panel 4 start to move together in the closing direction. When the driving device 5 continues to be driven and the first door panel 3 and the second door panel 4 reach the closed position (in a state where the first door panel 3 is in the closed position), the locking device has the connecting portion 720 in the second position. It is allowed to change the position from P2 to the first position P1. Thereby, if the output part 53 of the drive device 5 continues to move to the other side in the lateral direction, the force directed to the other side in the lateral direction (the closing direction of the first door panel 3) is transmitted to the first door panel 3. Without changing the position of the connecting portion 720 of the operation lever 72 from the second position P2 to the first position P1. Accordingly, the operation lever 72 widens the distance between the pair of vanes 71. Accordingly, the pair of vanes 71 with respect to the pressure receiving portion 61 of the second door lock device 6 is released, and the biasing with respect to the operating portion 60 is released. As a result, the second door lock device 6 is in a state in which the second door panel 4 is restricted from moving in the lateral direction.

  When the connecting portion 720 of the operation lever 72 reaches the first position P1, the distance between the pair of vanes 71 is widened, and when the car 2 moves up and down along the hoistway R, the second door panel 4 The operating part 60 and the pressure receiving part 61 of the connected second door lock device 6 are in a state where they can be pulled out from between the pair of vanes 71 in the vertical direction. Further, in this state, as described above, when the car 2 is raised and lowered later, the operating portion 60 and the pressure receiving portion 61 of the second door lock device 6 can pass (intervene) between the pair of vanes 71.

  Thus, since the door engaging device 7 of the elevator 1 having the above-described configuration can link the start and stop of the first door panel 3 and the second door panel 4, the door panel 3 without making the user feel uncomfortable. 4 can be opened and closed.

  Moreover, the door engaging device 7 of the elevator 1 according to the present embodiment is two or more link bodies 740 that are arranged at intervals in the vertical direction, each of which is in the middle between both ends and the both ends. And both ends are connected to a pair of vanes 71 so as to be rotatable about an axis extending in the depth direction perpendicular to the vertical direction and the horizontal direction, and an intermediate portion rotates an axis extending in the depth direction. Two or more link bodies 740 provided to be rotatable about the center are further provided, and the operation lever 72 is provided to be rotatable around an axis extending in the depth direction and is rotated forward and backward around the axis to thereby connect the connecting portion 720. Is changed to the first position P1 and the second position P2, and the two or more link bodies 74 are changed as the connecting portion 720 changes position from the first position P1 to the second position P2. One end of the link body 740 is pressed toward the one end side of the link body 740, while the connecting portion 720 is moved from the second position P2 to the first position P1 to change the position of the link body 740 to the one end side. There is provided a pressing portion 724 that releases the pressing against the.

  If it does in this way, two or more link bodies 740 and a pair of vanes 71 constitute a parallel link. And the connection part 720 of the operation lever 72 follows the movement of the output part 53 of the drive device 5, and the position is changed between the first position P1 and the second position P2, so that the operation lever 72 is moved around one axis. Rotate to the side or the other side. Then, when the connecting portion 720 is changed from the first position P1 to the second position P2 and the operation lever 72 is rotated to one side around the axis, the pressing portion 724 of the operation lever 72 is the rotation center (intermediate of the link body 740). The link body 740 is rotated. Thereby, a pair of vane 71 narrows a space | interval. On the other hand, when the connecting portion 720 is changed from the second position P2 to the first position P1 and the operation lever 72 is rotated to the other side around the axis, the pressing portion 724 of the operation lever 72 is the rotation center of one link body 740. The link body 740 is allowed to rotate away from the position away from the position. Thereby, a pair of vane 71 spreads a space | interval rapidly. Therefore, it is possible to reliably and satisfactorily perform the urging and releasing of the operating portion 60 of the second door lock device 6 by the pair of vanes 71 and the sandwiching and releasing of the pressure receiving portion 61.

  Further, in the present embodiment, the lock mechanism 73 includes a lock lever 730 provided to be rotatable around an axis extending in the depth direction, and the lock lever 730 rotates around the axis so that the connecting portion 720 is moved to the first position. It is configured to be switchable between a state where it is engaged with the operation lever 72 positioned at the second position P2 and a state where the engagement with the operation lever 72 where the connecting portion 720 is positioned at the second position P2 is released.

  By doing so, the lock lever 730 is simply rotated, and the connecting portion 720 is engaged with the operation lever 72 positioned at the second position P2, and the connecting portion 720 is positioned at the second position P2. The engagement with the operation lever 72 can be switched to the released state. Therefore, the operation lever 72 can be restricted and released without complicating the structure.

  Further, the lock lever 730 has a contact portion 734 that can contact the striker S fixed to the car 2, and the contact portion 734 contacts the striker as the first door panel 3 moves in the closing direction. Since it is configured to be disengaged from the operation lever 72 in which the connecting portion 720 is positioned at the second position P2 in a state in which the first door panel 3 reaches the closed position in contact with and rotates around the axis. In response to the arrangement state of the first door panel 3, the restriction of the operation lever 72 can be mechanically released.

  Furthermore, the door engaging device 7 of the elevator 1 according to the present embodiment includes a biasing means 75 that biases the operation lever 72 so as to change the position of the connecting portion 720 from the second position P2 toward the first position P1. Therefore, the urging force by the urging means 75 is constantly acting on the operation lever 72. As a result, when the lock mechanism 73 releases the restriction of the operation lever 72, the position of the connecting portion 720 is reliably changed from the second position P2 to the first position P1. That is, the operation of the operation lever 72 in a state where the restriction by the lock mechanism 73 is released becomes good.

  Furthermore, the door engaging device 7 of the elevator 1 according to the present embodiment includes a first door lock device 76 that restricts the first door panel 3 in the closed position from moving in the opening direction, and the first door lock device 76. Includes a first lock arm 760 supported directly or indirectly by the first door panel 3, and a first striker 761 fixed to the vane 71 movably provided in the lateral direction of the pair of vanes 71. The first lock arm 760 is a first arm main body 760a having a tip end portion and a base end portion in a uniaxial direction, and the base end portion can be directly rotated on an axis extending in the depth direction directly to the first door panel 3. A first arm main body 760a that is supported manually or indirectly, and a first collar 760b that is connected to the tip of the first arm main body 760a, and is locked to the first receiving member R1 fixed to the car 2 OK A first abutting portion 760b and a first abutting portion 760c fixed at a position shifted from the rotation center at the base end portion of the first arm main body 760a, and the first striker 761 includes a first abutting portion 760c. The first door panel 3 is provided so as to be able to contact in the opening direction.

  In this way, when the output portion 53 of the drive device 5 moves in the opening direction of the first door panel 3 while the first door panel 3 is in the closed position, the vane 71 moves in the lateral direction as described above. The distance between the pair of vanes 71 is narrowed. Accordingly, as the vane 71 moves in the lateral direction (opening direction of the first door panel 3), the first striker 761 fixed to the vane 71 also moves in the lateral direction (opening direction of the first door panel 3). Accordingly, the first striker 761 comes into contact with the first contact portion 760c. Since the first contact portion 760c is fixed at a position shifted from the rotation center at the base end portion of the first arm main body 760a, the contact force of the first striker 761 with respect to the first contact portion 760c is the first arm. The main body 760a is rotated to one side around the axis. Thereby, the latch of the 1st collar part 760b with respect to 1st receiving member R1 is cancelled | released, and the movement of the opening direction of the 1st door panel 3 is accept | permitted. Therefore, the output part 53 of the drive device 5 can continue to move in the opening direction of the first door panel 3, whereby the first door panel 3 can be moved to the open position. Moreover, when the output part 53 of the drive device 5 moves in the closing direction of the first door panel 3 and the first door panel 3 reaches the closing position, the distance between the pair of vanes 71 is widened as described above. Accordingly, as the vane 71 moves in the lateral direction (the closing direction of the first door panel 3), the first striker 761 fixed to the vane 71 also moves in the lateral direction (the closing direction of the first door panel 3). Accordingly, the first striker 761 is separated from the first contact portion 760c, and the force in the opening direction does not act on the first contact portion 760c. As a result, the first arm main body 760a rotates to the other side around the axis, and the first flange 760b is locked to the first receiving member R1.

  Therefore, when the first door panel 3 is in the closed position, the first hook portion 760b of the first lock arm 760 supported directly or indirectly by the first door panel 3 is fixed to the car 2. Locked to the member R1. As a result, the first door panel 3 in the closed position is reliably restricted from inadvertently moving in the opening direction.

  Further, in the present embodiment, the first door lock device 76 further includes a second striker 762 fixed to the vane 71 movably provided in the lateral direction, and the first lock arm 760 includes the first arm body 760a. A second abutting portion 760d fixed at a position deviated from the rotation center at the base end of the second abutting portion 760d disposed at a position sandwiching the rotation center between the first abutting portion 760c and the first arm body 760a. The contact portion 760d is further provided, and the second striker 762 is provided so as to be able to contact the second contact portion 760d in the closing direction of the first door panel 3.

  In this way, when the force in the opening direction is applied to the first door panel 3 in a state in which the operation portion 60 and the pressure receiving portion 61 of the second door lock device 6 are between the pair of vanes 71, the first door lock The lock | rock with respect to the 1st door panel 3 by the apparatus 76 is cancelled | released, and the movement of the opening direction of the 1st door panel 3 is accept | permitted. Specifically, when the first door panel 3 tries to move in the lateral direction (opening direction), one vane 71 (the vane 71 on the closing direction side of the first door panel 3) out of the pair of spaced vanes 71. ) Hits the operating part 60 or the pressure receiving part 61 of the second door lock device 6. Accordingly, a lateral force acts on the vane 71, and the vane 71 is urged toward the closing direction of the first door panel 3 and tries to move in the same direction. Since the second striker 762 is fixed to the vane 71 movable in the lateral direction, the second striker 762 moves together with the vane 71 in the closing direction of the first door panel 3.

  The second contact portion 760d is disposed at a position sandwiching the first contact portion 760c and the rotation center of the arm body, and the second striker 762 closes the first door panel 3 with respect to the second contact portion 760d. Since the second striker 762 abuts against the second abutment portion 760d, the abutment force of the second striker 762 against the second abutment portion 760d causes the first arm body 760a to contact the second abutment portion 760d. Rotate to one side around the axis. Thereby, the latch of the 1st collar part 760b with respect to 1st receiving member R1 is cancelled | released, and the movement of the opening direction of the 1st door panel 3 is accept | permitted. Accordingly, the first door panel 3 can be opened only when a power failure or disaster occurs in a state where the car 2 corresponds to the building floor F (when the driving device 5 cannot be driven). , It is possible to prevent the user from being trapped in the car 2.

  As described above, the elevator 1 (elevator door engagement device 7) according to the present embodiment can exhibit an excellent effect that the door panel can be opened and closed without making the user feel uncomfortable.

  In addition, this invention is not limited to the said embodiment, Of course, it can change suitably in the range which does not deviate from the summary of this invention.

  For example, in the above embodiment, the operation lever 72 is provided so as to be rotatable around an axis extending in the depth direction, and the connection portion 720 can be changed between the first position P1 and the second position P2 by the rotation of the operation lever 72. However, the present invention is not limited to this. For example, at least one vane 71 on the closing direction side of the first door panel 3 of the pair of vanes 71 is provided to be movable in the horizontal direction, and the operation lever 72 is provided to be movable in the horizontal direction. It may be connected to the vane 71. In this way, the operating lever 72 moves in the horizontal direction, so that the connecting portion 720 changes to the first position P1 and the second position P2, and the vane 71 moves in the horizontal direction in accordance with the position change. By moving, the interval between the pair of vanes 71 can be changed.

  In the said embodiment, although the door engaging apparatus 7 was provided in the cage | basket 2 on the assumption that the drive apparatus 5 was provided in the cage | basket | car 2, it is not limited to this. For example, the door panel of the car 2 is the second door panel 4, the door panel of the floor F is the first door panel 3, the driving device 5 and the door engaging device 7 are provided on the floor F of the building, and the car 2 is A door lock device 6 may be provided. In this case, since it is necessary to provide the driving device 5 for each level F of the building, in consideration of cost and maintenance, the driving device 5 and the door engagement device 7 are attached to the car 2 as in the above embodiment. Needless to say, it is preferable to provide the second door lock device 6 in the layer F.

  In the above embodiment, the drive device 5 includes the pair of pulleys 50 and the endless annular drive belt 51 spanned between the pair of pulleys 50, and a part of the drive belt 51 is the output unit 53, but the present invention is not limited thereto. Not. For example, a hydraulic or pneumatic or electric cylinder may be used as the driving device 5. In this case, by installing the cylinder so that the axis of the rod extends in the lateral direction, the rod end becomes the output unit 53 that reciprocates in the lateral direction. Accordingly, the connecting portion 720 of the operation lever 72 in the door engaging device 7 may be connected to the rod end.

  In the said embodiment, although the door engaging apparatus 7 was provided with the 1st door lock apparatus 76, it is not limited to this, The 1st door lock apparatus 76 should just be provided as needed.
