  The movable vane 11 is lifted upward by the link 20 or the like when the car side doors 106b and 106b are moved by the door opening / closing device 2 or the like from the fully closed state in a direction to open the doorway 106a. In addition, the movable vane 11 is lifted upward by the link 20 or the like, thereby applying a door closing force (force for closing the car side doors 106b and 106b) to the car side doors 106b and 106b. The movable vane 11 is disposed closer to the other car side door 106b than the engagement vane 10 is. That is, the movable vane 11 is provided in front of the moving direction when the car side doors 106b and 106b are moved from the fully closed state to the direction of opening the entrance / exit 106a. The movable vane 11 is formed in a thin strip shape extending in the vertical direction and parallel to the car-side doors 106b and 106b. The movable vane 11 includes wide portions 11a that are wider than the engagement vanes 10 at both upper and lower ends.

  In addition, the engagement device 1 includes a weight 12, a roller 13, and a cam plate 14, as shown in FIGS. The weight 12 is formed in a strip shape thicker than the movable vane 11, and is attached to the surface of the movable vane 11 facing the hole side doors 110b and 110b from the center to the lower end thereof. It has been. The weight 12 extends linearly in the vertical direction.

  The roller 13 is rotatably provided on a support plate 15 extending from the central portion of the movable vane 11 toward the other car side door 106b. That is, the roller 13 is rotatably provided on the movable vane 11. The axis that forms the rotation center of the roller 13 is parallel to the horizontal direction and parallel to the direction in which the doors 106b and 110b face each other. Further, the roller 13 is rotatably provided on the support plate 15 so that the position of the axis that forms the center of rotation does not shift with respect to the support plate 15.

  When the car-side doors 106b and 106b are moved from the fully closed state to the opening direction, the cam plate 14 rides on the roller 13 and moves the roller 13 upward to lift the movable vane 11 upward. The cam plate 14 is fixed to the upper end of the car room 106 of the car 103 and extends linearly in the width direction of the car room 106. That is, the cam plate 14 is provided in the car room 106 of the car 103. The cam plate 14 is provided from the vicinity of the roller 13 when the car side doors 106b and 106b are fully closed to the end of the car chamber 106 on the side away from the engagement device 1. The cam plate 14 is integrally provided with an upper inclined portion 14a in the vicinity of the roller 13 and a horizontal portion 14b connected to the upper inclined portion 14a.

  The upward inclined portion 14a gradually extends upward as it moves away from the roller 13. When the car-side doors 106b and 106b are moved from the fully closed state to the opening direction, the roller 13 comes into contact with the surface of the upper inclined portion 14a and moves the roller 13 upward while rotating. The horizontal portion 14b extends in the horizontal direction, and maintains the roller 13 in a state where the roller 13 is lifted more than when the car-side doors 106b and 106b are fully closed while rotating the roller 13.

  In the engaging device 1 having the above-described configuration, the engaging vane 10 includes the intrusion portion 10b, and the movable vane 11 is formed in a band plate shape that does not have a portion that contacts the roller 111a. Used after replacement. That is, the engagement device 1 is used for a relatively new elevator 101.

  In the engaging device 1 having the above-described configuration, when the car 103 is landed, the intruding portion 10b of the engaging vane 10 enters between the rollers 111a provided on the one hall side door 110b of the floor 110 on which the landing is made. Thus, it engages with the old interlock 111 used after the renewal. When the motor 3 is driven to open the car-side doors 106b and 106b according to a command from the control panel 107, the engaging vane 10 causes one of the rollers 111a to move to the other car-side door 106b. Push towards. Then, the interlock 111 is unlocked, and the hall side doors 110b and 110b are moved together with the car side doors 106b and 106b in the direction of opening from the fully closed state. Further, when the car doors 106b and 106b are moved from the fully closed state in a direction to open the entrance / exit 106a, the roller 13 contacts the upper inclined portion 14a and is then guided and moved upward by the upper inclined portion 14a. . Then, the cam plate 14 lifts the weight 12 and the movable vane 11 together with the roller 13. The cam plate 14 lifts the weight 12 and the movable vane 11 together with the roller 13 to apply a door closing force to the car-side doors 106b and 106b. The door closing force is a force corresponding to the mass of the lifted roller 13, the weight 12, the movable vane 11, and the like. That is, the cam plate 14 lifts the weight 12 and the movable vane 11 together with the roller 13 so that only when the roller 13 is in the upper inclined portion 14a, the mass of the roller 13, the weight 12, the movable vane 11 and the like is combined. It acts on the car side doors 106b and 106b as a door closing force.

  According to the engagement device 1 of the embodiment, the engagement vane 10 is provided at a position where the engagement vane 10 enters between the rollers 111a of the interlock 111 provided in the one hall side door 110b. For this purpose, the current mainstream engagement device 1 including the engagement vane 10 and the movable vane 11 connected to the engagement vane 10 via the link 20 is replaced with an old elevator including a pair of rollers 111a and the like. It can be engaged with the interlock 111 used. Therefore, the engaging device 1 can be used also for the elevator 101 after renewal provided with the interlock 111 used for the old elevator. Therefore, according to the engagement device 1 of the embodiment, it is possible to renew the low-cost elevator 101 in which the interlock 111 or the like can be used as it is.

  Further, the movable vane 11 connected to the engagement vane 10 via the link 20 is lifted upward when the car side doors 106b and 106b are moved in the opening direction, and is closed to the car side doors 106b and 106b. Apply force. For this reason, even if the elevator 101 is stopped due to loss of power, the mass of the movable vane 11 or the like becomes a resistance when the car side doors 106b and 106b are forced to open. Therefore, the engagement device 1 can suppress the passengers in the car 103 from opening the car-side doors 106b and 106b. Therefore, according to the engagement device 1 of the embodiment, a sufficient door closing force can be maintained even after low-cost renewal.

  Further, according to the engagement device 1 of the embodiment, the weight 12 and the roller 13 are attached to the movable vane 11, and the cam plate 14 is provided with the roller 13 provided in the car chamber 106 when the car side doors 106b and 106b are opened. Rotate on the surface. For this reason, when a passenger in the car 103 attempts to forcefully open the car side doors 106 b and 106 b, the roller 13 moves on the upper inclined portion 14 a of the cam plate 14. The upper inclined portion 14a of the cam plate 14 lifts the roller 13, the movable vane 11 and the weight 12 upward. For this reason, even if the elevator 101 is stopped due to loss of the power source, the masses such as the movable vane 11 and the weight 12 become resistance when the car side doors 106b and 106b are forcibly opened. Therefore, the engagement device 1 can suppress the passengers in the car 103 from opening the car-side doors 106b and 106b. Therefore, according to the engagement device 1 of the embodiment, a sufficient door closing force can be reliably maintained even after low-cost renewal.

  Further, according to the engagement device 1 of the embodiment, since the intrusion portion 10b of the engagement vane 10 extends linearly in the vertical direction, it can surely enter between the pair of rollers 111a. Further, the intrusion portion 10b is longer than the main body portion 10a parallel to the car side doors 106b and 106b of the engagement vane 10. For this reason, in order to arrange the engagement vane 10 between the car 103 and the interlock 111, even if the thickness of the main body 10a is suppressed, the mass of the engagement vane 10 is reduced in the current mainstream engagement device. It can be equivalent to the mass of things. Therefore, the control of the motor 3 and the like for opening and closing the car side doors 106b and 106b can be made equivalent to that of the current mainstream engagement device, and the renewal at a lower cost can be performed more reliably.

  Further, according to the engagement device 1 of the embodiment, since the movable vane 11 is formed in a strip shape parallel to the car-side doors 106b and 106b, the movable vane 11 is securely attached to the car 103 and the interlock 111. Can be placed between. Therefore, the engagement device 1 can be reliably engaged with the old interlock 111 including the pair of rollers 111a and the like.

  Further, according to the engaging device 1 of the embodiment, the movable vane 11 includes the wide portion 11 a wider than the engaging vane 10. For this reason, the mass of the movable vane 11 can be made equal to the mass of the current mainstream engagement device having a portion that sandwiches the roller 111a between the intrusion portion 10b of the engagement vane 10. Therefore, the control of the motor 3 and the like for opening and closing the car side doors 106b and 106b can be made equivalent to that of the current mainstream engagement device, and the renewal at a lower cost can be performed more reliably.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention. These embodiments and their modifications are included in the scope and gist of the invention, and are also included in the invention described in the claims and the equivalents thereof.
