Each part 5a to 5d of the processing device 5 is realized by the processor executing the program stored in the memory and by the cooperation of software and hardware.

As shown in FIGS. 1 to 3, the linear motor 3, which is the car drive unit 3, is connected to the motor stator 3a fixed to the hoistway and the car 2, for example, as in the present embodiment. and a motor mover 3b movable with respect to the motor stator 3a. For example, the motor mover 3b may have a magnet, and the motor stator 3a may have a coil that applies an electromagnetic force to the magnet in the vertical direction D3.

Although not particularly limited, in the elevator 1, for example, as in the present embodiment, a pair of linear motors 3 may be provided so as to sandwich the car 2 in the second lateral direction D2. Although not particularly limited, in each linear motor 3, for example, a pair of motor movers 3b may be provided apart in the vertical direction D3 as in the present embodiment.

For example, the car 2 is connected to a car main body 8 having a car chamber 8a and a car frame 8b, and a motor mover 3b, as in the present embodiment, and is guided by car rails 4a to 4d. The car guide portions 9 and 10 and the car connection portion 2a that connects the car guide portions 9 and 10 and the car body portion 8 may be provided.

The car connecting portion 2a connects the car guide portions 9, 10 and the car body portion 8 so that the car guide portions 9, 10 are movable relative to the car body portion 8, for example, as in the present embodiment. good too. As a result, for example, it is possible to suppress transmission of vibrations of the car guide portions 9 and 10 to the car chamber 8a of the car body portion 8 . Although not particularly limited, the car connecting portion 2a may be, for example, an elastic member (for example, laminated rubber or the like).

For example, the first and second car guide parts 9 and 10 may be arranged so as to sandwich the car 2 in the second lateral direction D2 as in the present embodiment. In this embodiment, since a pair of motor movers 3b are provided separately in the vertical direction D3 for one linear motor 3, each of the first and second car guides 9 and 10 also A pair may be provided separately in the vertical direction D3.

For example, the car guide portions 9 and 10 are connected to the guide frame portions 9a and 10a fixed to the car connection portion 2a and the guide frame portions 9a and 10a and guided to the car rails 4a to 4d as in the present embodiment. Guided portions 9b and 10b may be provided. Although not particularly limited, the guided portions 9b and 10b may be, for example, rollers guided by the car rails 4a to 4d as in the present embodiment.

Although not particularly limited, the rollers include rollers that contact the car rails 4a to 4d in the first lateral direction D1 and rollers that contact the car rails 4a to 4d in the second lateral direction D2. For example, the position may be fixed relative to the guide frames 9a and 10a. As a result, the car guide portions 9 and 10 can be prevented from moving in the lateral directions D1 and D2 with respect to the car rails 4a to 4d.

The number of car rails 4a to 4d is not particularly limited, and may be, for example, two, or may be, for example, four as in the present embodiment. Specifically, for example, as in the present embodiment, the car rails 4a to 4d are configured to guide the first and third car rails 4a and 4c that guide the first car guide portion 9 and the second car guide portion 10. and second and fourth car rails 4b, 4d.

The first and third car rails 4a, 4c and the second and fourth car rails 4b, 4d may be separated in the second lateral direction D2 so as to sandwich the car 2 therebetween. Also, the first and third car rails 4a, 4c may, for example, be spaced apart in the first lateral direction D1 and the second and fourth car rails 4b, 4d may, for example, be spaced apart in the first lateral direction D1. You can stay away.

As shown in FIGS. 2 and 3, the elevator 1 includes, for example, a stopping device 11 for stopping the car 2 on the car rails 4a to 4d and a stopping device 11 for stopping the car 2 on the car rails 4a to 4d. 4d, a release device 12 (only shown in FIG. 2) for releasing the stopped state. A device including the car 2 and the stopping device 11 is called an elevator car device 1a, for example.

For example, as in the present embodiment, the stopping device 11 is connected to the plurality of stopping portions 13 so that the plurality of stopping portions 13 and the plurality of stopping portions 13 are interlocked, and transmits force to the plurality of stopping portions 13. A transmission unit 14 may be provided. In this embodiment, the stopping device 11 is connected to the lower first and second car guide portions 9 and 10, but for example, the stop device 11 is connected to the upper first and second car guide portions 9 and 10. may have been

The number of stopping portions 13 is not particularly limited, and may be, for example, two, or may be, for example, four as in the present embodiment, as long as the car 2 can be stopped on the car rails 4a to 4d. good. Further, for example, as in the present embodiment, the number of stop portions 13 may be the same as the number of car rails 4a to 4d.

Each stop portion 13 is connected to, for example, the stop fixing portion 15 fixed to the car guide portions 9 and 10 and the transmission portion 14 as in the present embodiment, and is movable with respect to the stop fixing portion 15. A stop movable portion 16 may be provided. The stop movable part 16 has, for example, a stop position (see FIG. 4) in which the car 2 is stopped in cooperation with the stop fixed part 15 by coming into contact with the stop fixed part 15, and a waiting position (see FIG. 3) below the stop position. ), it may be movable with respect to the stop fixing part 15 .

For example, as in the present embodiment, the transmission section 14 is fixed to the first and second shafts 14a and 14b and the shafts 14a and 14b that are rotatable about the first lateral direction D1, and is fixed to the stop movable section 16. Rotation members 14c to 14f that are rotatably connected may be provided. As a result, the shafts 14a and 14b rotate in conjunction with each other, so that the rotating members 14c to 14f rotate in conjunction with each other.

The stopping device 11 includes, for example, a first emergency stop mechanism 17 that moves the stop movable part 16 to a stop position when the car 2 moves downward at a set acceleration, and a first emergency stop mechanism 17 that moves the car 2 at a set speed. and a second emergency stop mechanism 18 that moves the stop movable part 16 to the stop position when the stop movable part 16 moves to the stop position. Further, the stop device 11 may include, for example, the base portion 19 connected to the first car guide portion 9 and the second car guide portion 10 as in the present embodiment.

Here, the configuration of the first emergency stop mechanism 17 will be described with reference to FIGS. 4 and 5. FIG. The first emergency stop mechanism 17 is also called an overacceleration stop mechanism. Also, the configuration of the first emergency stop mechanism 17 is not limited to the following configuration.

As shown in FIG. 4, the first emergency stop mechanism 17 includes, for example, a stop elastic portion 20 that moves the stop movable portion 16 to the stop position by elastic restoring force, and a stop movable portion 16 that stands by, as in the present embodiment. and a support portion 21 that supports the weight of the stop movable portion 16 when positioned at the position. Note that, for example, the stop portion 13 and the transmission portion 14 may constitute the first emergency stop mechanism 17 as in the present embodiment.

The stationary movable portion 16 includes, for example, a wedge-shaped movable body portion 16a and a movable connection portion 16b that connects the movable body portion 16a and the rotating members 14c to 14f of the transmission portion 14, as in the present embodiment. may be provided. Then, for example, when the stop movable portion 16 is positioned at the stop position, the movable body portion 16a cooperates with the stop fixing portion 15 to press and contact the car rails 4a to 4d, thereby causing the car 2 to It may be configured to stop on the car rails 4a to 4d.

For example, as in the present embodiment, the transmission portion 14 is fixed to the elongated member 14g rotatably connected to the first and second rotating members 14c and 14d, the base portion 19, and the stopping elastic portion 20. A first holding member 14h that holds the first end and a second holding member 14i that is fixed to the long member 14g and holds the second end of the stop elastic portion 20 may be provided. Note that the first and second shafts 14a and 14b of the transmission section 14 may be rotatably connected to the base section 19 as in the present embodiment, for example.

For example, the stop elastic portion 20 may be elastically deformed in the longitudinal direction of the long member 14g as in the present embodiment. Thereby, the elastic restoring force of the stop elastic portion 20 is transmitted to the stop movable portion 16 by the transmission portion 14 . Although not particularly limited, the stop elastic portion 20 may be, for example, a coiled spring as in the present embodiment.

For example, the support portion 21 may directly support the movable stop portion 16 from below as in the present embodiment, or may indirectly support the movable stop portion 16 by supporting the transmission portion 14, for example. You may support it. As a result, when the movable stop portion 16 is positioned at the standby position, the weight of the movable stop portion 16 is supported by the support portion 21, so that the elastic stop portion 20 is elastically deformed.

Therefore, the standby position is located above the balanced position. The balanced position is a position where the weight of the stop movable portion 16 is balanced with the elastic recovery amount of the stop elastic portion 20 when the acceleration of the car 2 is zero.

Here, the operation of the first emergency stop mechanism 17 will be described with reference to FIGS. 4 and 5. FIG. Note that the operation of the first emergency stop mechanism 17 is not limited to the following operation.

As shown in FIG. 4, for example, when the acceleration of the car 2 is zero, the stop elastic part 20 receives the weight of the stop movable part 16 (more specifically, including the weight of the transmission part 14 and the like). , elastically deforms to contract. On the other hand, when the car 2 moves downward with acceleration, an upward inertial force (specifically, the mass of the movable stop portion 16 and the movement acceleration of the car 2 and the product) works.

As a result, when the apparent weight of the stop movable portion 16 (the resultant force of the gravity and the inertial force due to the mass) becomes smaller than the upward elastic restoring force applied to the stop movable portion 16 by the stop elastic portion 20, , the stop movable part 16 moves upward. The smaller the apparent weight of the movable stop portion 16, that is, the greater the downward acceleration of the car 2, the greater the amount of elastic recovery of the elastic stop portion 20. Therefore, the position of the movable stop portion 16 is shifted upward. Become.

Therefore, when the downward acceleration of the car 2 becomes equal to or greater than the reference acceleration, the stationary movable portion 16 moves upward from the standby position. As a result, for example, when the downward acceleration of the car 2 is less than the reference acceleration, it is possible to suppress the movement of the stop movable portion 16 from the standby position.

Although not particularly limited, the reference acceleration may be, for example, greater than the rated acceleration (maximum acceleration during normal operation) of the car 2, and may be, for example, 10% of gravitational acceleration. As a result, the stop movable portion 16 can be held at the standby position when the car 2 is in normal operation. Therefore, for example, it is possible to suppress unnecessary movement of the stop movable portion 16 in the vertical direction D3.

Further, for example, when a passenger jumps in the car 2, the downward acceleration of the car 2 may momentarily become about 50% of the gravitational acceleration. Therefore, it is preferable to set the reference acceleration to 50% of the gravitational acceleration, for example. As a result, for example, when a passenger jumps in the car 2, it is possible to suppress the movable stop portion 16 from moving in the vertical direction D3.

Then, when the car 2 moves downward at the set acceleration, as shown in FIG. 5, the stop movable part 16 moves upward to the stop position. As a result, the stop movable portion 16 cooperates with the stop fixed portion 15 to stop the car 2 on the car rails 4a and 4b. Therefore, when the car 2 moves downward at the set acceleration, the stopping device 11 can stop the car 2 on the car rails 4a and 4b without using an electric signal. Although not particularly limited, the set acceleration may be, for example, 70% to 90% of the gravitational acceleration.

For example, after the first emergency stop mechanism 17 is operated and the car 2 is stopped on the car rails 4a to 4d by the stopping device 11, the stop movable part 16 is operated by, for example, a releasing device to restore the elevator 1. 12 (see FIG. 2) is moved downwards from the rest position. At this time, since there is nothing to hinder the movement of the stop movable part 16, the stop movable part 16 moves to the standby position by its own weight. Therefore, the stop movable part 16 (first emergency stop mechanism 17) automatically moves to the standby position without using an electric signal or the like.

By the way, in this embodiment, the first and second car guide portions 9 and 10 are movable with respect to the car body portion 8 by the car connection portion 2a (see FIG. 3). On the other hand, as shown in FIG. 5, the base portion 19 includes, for example, a first connection portion 19a rotatably connected to the first car guide portion 9 and a second car guide portion, as in the present embodiment. A second connecting portion 19b movably connected to 10 may be provided.

As a result, when the first and second car guide portions 9 and 10 move with respect to the car body portion 8, the base portion 19 moves with respect to the car body portion 8. 8. Therefore, even when the first and second car guide portions 9 and 10 move with respect to the car body portion 8, the position of the stop movable portion 16 with respect to the stop fixed portion 15 can be made appropriate.

Although not particularly limited, the second connection portion 19b of the base portion 19 may be, for example, a long guide hole for guiding the connected portion 10c of the second car guide portion 10 on the inner peripheral surface as in the present embodiment. good. As a result, the second connection portion 19b of the base portion 19 is movable with respect to the second car guide portion 10, and the first connection portion 19a of the base portion 19 is rotatable with respect to the first car guide portion 9. It becomes possible.

Next, the configuration of the second emergency stop mechanism 18 will be described with reference to FIG. The second emergency stop mechanism 18 is also called an overspeed stop mechanism. Also, the configuration of the second emergency stop mechanism 18 is not limited to the following configuration.

As shown in FIG. 6, the second emergency stop mechanism 18 includes, for example, a speed regulator 22 that detects the moving speed of the car 2 and a movable stop mechanism 16 that moves to the stop position as in the present embodiment. , a stop force applying portion 23 that applies an upward force to the movable stop portion 16; and may be provided. For example, as in the present embodiment, the stop portion 13 and the transmission portion 14 (specifically, the shafts 14a and 14b, the rotating members 14c to 14f, and the long member 14g) constitute the second emergency stop mechanism 18. You may have

For example, as in the present embodiment, the speed control section 22 is configured by a governor roller 22a rotatably connected to the first car guide section 9, and rotating about the revolution axis as the governor roller 22a rotates. It may include revolving weights 22b, 22b, a weight connecting portion 22c connecting the governor roller 22a and the weight 22b, and a speed control elastic portion 22d applying an elastic restoring force to the weight 22b in a direction approaching the revolution axis. .

The governor roller 22a may be arranged, for example, in contact with the third car rail 4c as in the present embodiment. As a result, the governor roller 22a rotates as the car 2 moves. Therefore, the faster the moving speed of the car 2 is, the greater the centrifugal force acting on the weight 22b is, so that the position of the weight 22b is farther from the revolution axis. Then, when the car 2 moves at the set speed, the weight 22b is positioned at the set position.

For example, the governor roller 22a may be configured to rotate with the movement of the car 2 by coming into contact with a rail other than the car rails 4a to 4d. As described above, although not particularly limited, in the stopping device 11 according to the present embodiment, the speed controlling section 22 without a governor rope, that is, the speed controlling section 22 of a governor rope press can be used. Further, the weight connecting portion 22c may include, for example, as in the present embodiment, a velocity-controlled moving portion 22e that moves in the second lateral direction D2 as the weight 22b moves away from the revolution axis.

Further, for example, as in the present embodiment, the transmission portion 14 includes an engaging portion 14j fixed to the first shaft 14a in order to receive force from the stop force applying portion 23, and the stop force applying portion 23 is A configuration may be employed in which an operating portion 23a that pushes the engaging portion 14j by operating is provided. As a result, the stop force applying portion 23 is separated from the transmission portion 14, so that the operation of the transmission portion 14 by the elastic restoring force of the stop elastic portion 20 (see FIGS. 4 and 5), that is, the movement of the stop elastic portion 20 The movement of the stop movable portion 16 due to the elastic restoring force is not hindered by the stop force applying portion 23 .

For example, in order to apply an elastic restoring force to the movable stop portion 16, the stop force applying portion 23 includes, for example, the force applying elastic portion 23b that applies an elastic restoring force to the operating portion 23a, and the first car guide portion. A first holding member 23c that is fixed to the connection member 24a fixed to 9 and holds the first end of the force applying elastic portion 23b, and a first holding member 23c that is fixed to the operating portion 23a and holds the second end of the force applying elastic portion 23b. A second holding member 23d may be provided.

For example, the force applying elastic portion 23b may be elastically deformed in the second lateral direction D2 in which the action portion 23a hits the engaging portion 14j, as in the present embodiment. As a result, the elastic restoring force of the force applying elastic portion 23b in the second lateral direction D2 is applied to the action portion 23a. Although not particularly limited, the force applying elastic portion 23b may be, for example, a coiled spring as in the present embodiment.

The starting part 24 includes, for example, a first rotating part 25 rotatably connected to the operating part 23a and a first stop for stopping the first end 25a of the first rotating part 25, as in the present embodiment. a second rotating portion 27 that cooperates with the first stopping portion 26 to stop the second end 25b of the first rotating portion 25 in order to prevent rotation of the first rotating portion 25; In order to prevent the rotation of the second rotating portion 27, a rotation preventing portion 28 for stopping the second rotating portion 27 may be provided.

As a result, the rotation preventing portion 28 prevents the second rotating portion 27 from rotating, and the first stopping portion 26 and the second rotating portion 27 prevent the first rotating portion 25 from rotating. Action is blocked. On the other hand, the first and second rotating parts 25 and 27 become rotatable when the rotation blocking part 28 releases the blocking of the rotation of the second rotating part 27. It works by elastic restoring force.

The second rotating portion 27 includes, for example, a second stopping portion 27a that contacts and stops the second end portion 25b of the first rotating portion 25, and a contact portion that is contacted and stopped by the rotation preventing portion 28, as in the present embodiment. It may be provided with a stopping portion 27b and a shaft portion 27c which is arranged between the second stopping portion 27a and the contacted portion 27b and serves as a rotation axis. Then, for example, as in the present embodiment, the contact stop portions 26 and 27a are arranged in the direction opposite to the direction of the elastic restoring force applied to the action portion 23a by the force applying elastic portion 23b (the direction of the arrow in the second direction D2). The end portions 25a and 25b of the first rotating portion 25 may be abutted.

For example, as in the present embodiment, the first stop portion 26 may be fixed to the connecting member 24a, and the rotation blocking portion 28 may be fixed to the speed control moving portion 22e. Also, the second rotating portion 27 may be rotatably connected to the connecting member 24a. That is, the position of the shaft portion 27c of the second rotating portion 27 may be fixed with respect to the revolution shafts of the first car guide portion 9 and the speed control portion 22, for example.

For example, as in the present embodiment, the force applied by the second rotating portion 27 to the rotation blocking portion 28 is applied by the force applying elastic portion 23b due to the principle of leverage of the first and second rotating portions 25 and 27. It may be smaller than the force applied to 23a. As a result, the frictional force generated between the second rotating portion 27 and the rotation blocking portion 28 can be reduced, so that the speed controlling moving portion 22e can move smoothly.

Moreover, the rotation blocking portion 28 may, for example, stop the contacted portion 27b of the second rotating portion 27 from above, as in the present embodiment. As a result, since the rotation blocking portion 28 does not receive the weight of the second rotating portion 27, the frictional force generated between the second rotating portion 27 and the rotation blocking portion 28 can be further reduced. Therefore, it is possible to further smoothen the movement of the speed controlling movement portion 22e.

Also, the abutted portion 27b may be, for example, a rolling body (for example, a roller). As a result, the frictional force generated between the second rotating portion 27 and the rotation blocking portion 28 can be efficiently reduced. Therefore, since the movement of the speed governing moving part 22e can be efficiently and smoothly performed, for example, the speed of the car 2 can be accurately detected by the speed governing part 22. FIG.

The operation of the second emergency stop mechanism 18 will now be described with reference to FIGS. 6 to 11. FIG. Note that the operation of the second emergency stop mechanism 18 is not limited to the following operation.

First, when the moving speed of the car 2 is less than the set speed, as shown in FIG. , 27 is blocked. As a result, the second rotating portion 27 is positioned at the pre-activation position, and the stop movable portion 16 is positioned at the standby position.

On the other hand, for example, when the car 2 moves downward at the set speed and the weight 22b moves to the set position as shown in FIG. It moves in the second lateral direction D2 to the position to be released. Therefore, the rotation of the first and second rotating parts 25 and 27 becomes possible.

As a result, as shown in FIG. 8, since the force applying elastic portion 23b is restored, the action portion 23a moves in the second lateral direction D2 to push the engaging portion 14j and restore the elasticity of the force applying elastic portion 23b. A restoring force is applied to the engaging portion 14j. Since the first shaft 14a rotates accordingly, the stop movable part 16 moves to the stop position.

Therefore, the movable stop portion 16 cooperates with the fixed stop portion 15 to stop the car 2 on the car rails 4a to 4d. As a result, when the car 2 moves at the set speed, the stopping device 11 can stop the car 2 on the car rails 4a to 4d without using an electric signal. Although not particularly limited, the set speed may be, for example, higher than the rated speed of car 2 (the maximum speed during normal operation), and may be, for example, 110% to 120% of the rated speed of car 2. .

When the moving speed of the car 2 is less than the set speed, the stop elastic portion 20 is not applied to the stop movable portion 16 even if the speed controlling portion 22e moves. The movement of the stop movable portion 16 due to the elastic restoring force is not hindered by the stop force applying portion 23 . That is, the movement of the movable stop portion 16 by the elastic stop portion 20 is independent of the movement of the movable stop portion 16 by the stop force applying portion 23 . As a result, for example, the acceleration when the stop movable part 16 is positioned at the stop position can be suppressed from deviating from the set acceleration.

Further, when the car 2 moves at the set speed, the stop force application part 23 starts applying force to the stop movable part 16 to move the stop movable part 16 to the stop position at once. That is, the movement of the movable stop portion 16 by the force-stopping portion 23 is independent of the movement of the movable stop portion 16 by the elastic stop portion 20 . As a result, for example, it is possible to suppress deviation of the speed when the stop movable portion 16 is located at the stop position from the set speed.

By the way, for example, after the second emergency stop mechanism 18 is operated and the car 2 is stopped on the car rails 4a to 4d by the stopping device 11, the stop movable part 16 is operated by, for example, a releasing device in order to restore the elevator 1. 12 (see FIG. 2) is moved downwards from the rest position. As shown in FIGS. 8 and 9, when the stop movable portion 16 is at the stop position, the second rotating portion 27 is at the post-activation position.

Then, for example, as in the present embodiment, the second rotating portion 27 moves in the direction returning to the pre-activation position (clockwise direction in FIGS. 6 to 11) at a position between the pre-activation position and the post-activation position. A rotating weight balance may also be used. Although not particularly limited, the second rotating portion 27 may include, for example, a weight portion 27d arranged on the contact portion 27b side with respect to the shaft portion 27c, as in the present embodiment.

As a result, as shown in FIG. 10, the second rotating portion 27 rotates to return to the pre-activation position as the stop movable portion 16 moves downward. Specifically, the second rotating portion 27 rotates to a position where the second stop portion 27 a of the second rotating portion 27 is stopped by the second end portion 25 b of the first rotating portion 25 .

Then, the contacted portion 27 b of the second rotating portion 27 contacts the engaging portion 29 fixed to the rotation blocking portion 28 . At this time, for example, as in the present embodiment, the force applied by the weight of the second rotating portion 27 to the engaging portion 29 may be greater than the elastic restoring force of the speed controlling elastic portion 22d. As a result, the engaging portion 29 moves in the second lateral direction D<b>2 due to the weight of the second rotating portion 27 . The modulus of elasticity of the speed controlling elastic portion 22d may be smaller than the modulus of elasticity of the stopping elastic portion 20 (see FIGS. 4 and 5) and the applying elastic portion 23b, for example.

Furthermore, as the stop movable portion 16 moves downward, the second rotating portion 27 further pushes the engaging portion 29, so that the engaging portion 29 moves further in the second lateral direction D2. Then, as shown in FIG. 11, the second rotating portion 27 rotates to the pre-activation position by moving the stop movable portion 16 to the standby position.

After that, the engaging portion 29, the rotation blocking portion 28, and the speed controlling portion 22e move in the second lateral direction D2 due to the elastic restoring force of the speed controlling elastic portion 22d. 28 prevents rotation of the second rotating part 27 . Therefore, by moving the stop movable part 16 from the stop position to the standby position, the activation part 24 (the second emergency stop mechanism 18) is automatically restored to the state before activation without using an electric signal or the like. Note that the activation unit 24 (the second emergency stop mechanism 18) may be configured to be restored to the state before activation by being manually operated, for example.

In this way, the elevator 1 according to the present embodiment can stop the car 2 without using an electric signal when the movement of the car 2 is abnormal (for example, when the car 2 moves downward at a set acceleration or moves at a set speed). 11 allows the car 2 to be stopped on the car rails 4a-4d. On the other hand, the elevator 1 may be provided with a normal stop mechanism 30 that stops the car 2 on the car rails 4a-4d by means of the stopping device 11 using an electric signal, for example, as in the present embodiment.

Next, the configuration of the normal stop mechanism 30 will be described with reference to FIGS. 12 to 14. FIG. Note that the normal stop mechanism 30 is also called a maintenance stop mechanism. Also, the configuration of the normal stop mechanism 30 is not limited to the following configuration.

As shown in FIGS. 12 to 14, the normal stopping mechanism 30 may include, for example, a rail holding portion 31 for holding the movable stop portion 16 on the car rail 4a as in the present embodiment. Note that, for example, the stopping portion 13 may constitute the normal stopping mechanism 30 as in the present embodiment.

For example, as in the present embodiment, the rail holding portion 31 includes a holding movable portion 31a movable with respect to the stop movable portion 16, a holding body portion 31b fixed to the movable connection portion 16b of the stop movable portion 16, A holding force applying portion 31c that applies a force to the movable holding portion 31a in a direction toward the car rail 4a and a holding elastic portion 31d that applies an elastic restoring force to the movable holding portion 31a in a direction away from the car rail 4a may be provided. .

The holding movable part 31a may move in the second lateral direction D2, for example, between a retracted position (see FIG. 13) away from the car rail 4a and a holding position (see FIG. 14) in contact with the car rail 4a. . Further, the distal end portion of the holding movable portion 31a may employ, for example, a configuration that does not easily slip on the car rail 4a.

For example, the coefficient of friction of the distal end portion of the movable holding portion 31a with respect to the car rail 4a may be greater than the coefficient of friction of the other portion of the movable holding portion 31a with respect to the car rail 4a. Further, for example, the distal end portion of the holding movable portion 31a may be formed of a magnet that is attracted to the car rail 4a.

For example, the holding body portion 31b may include a holding restricting portion 31e that restricts movement of the holding movable portion 31a relative to the stop movable portion 16 in the vertical direction D3, as in the present embodiment. For example, as in the present embodiment, the holding main body portion 31b is formed in a cylindrical shape so that the holding movable portion 31a is arranged inside, so that the holding restricting portion 31e is formed on the inner peripheral surface. 31e may be configured to be slid by holding movable portion 31a from the holding position to the retracted position.

As a result, the holding restricting portion 31e abuts and stops the holding movable portion 31a in the vertical direction D3 from the holding position to the retracted position. Therefore, the holding restricting portion 31e restricts the movable holding portion 31a from moving in the vertical direction D3 with respect to the movable stop portion 16 from the holding position to the retracted position.

Although not particularly limited, the holding force applying portion 31c may be, for example, an electromagnetic coil that applies an electromagnetic force to the holding movable portion 31a having magnetism, as in the present embodiment. Thus, the holding force applying portion 31c applies force to the movable holding portion 31a when energized, and does not apply force to the movable holding portion 31a when energization is stopped.

Further, although not particularly limited, the holding elastic portion 31d may be, for example, a spiral spring that elastically deforms in the moving direction of the holding movable portion 31a as in the present embodiment. For example, the rail holding portion 31 includes a projecting portion 31f fixed to the holding movable portion 31a and projecting outward from the holding body portion 31b, and a holding elastic portion 31d fixed to the projecting portion 31f and formed between the holding body portion 31b and the holding body portion 31b. It may be provided with a holding material 31g that holds the .

The force applied by the holding force applying portion 31c to the movable holding portion 31a may be, for example, greater than the force applied to the movable holding portion 31a by the elastic holding portion 31d as in the present embodiment. As a result, when the holding force applying portion 31c is energized, the holding movable portion 31a is positioned at the holding position (see FIG. 14) by the force of the holding force applying portion 31c. is stopped, the holding movable portion 31a is positioned at the retracted position by the force of the holding elastic portion 31d (see FIG. 13).

Note that the holding elastic portion 31d may be restored without being elastically deformed when the holding movable portion 31a is positioned at the retracted position, for example, as in the present embodiment. This makes it possible to reduce the amount of elastic deformation of the holding elastic portion 31d when the holding movable portion 31a is positioned at the holding position.

Therefore, when the movable holding portion 31a is positioned at the holding position, the elastic restoring force applied to the movable holding portion 31a by the elastic holding portion 31d is reduced. As a result, the pressure when the holding movable portion 31a comes into contact with the car rail 4a can be increased, so that, for example, the stop movable portion 16 can be reliably held on the car rail 4a.

Further, for example, a pair of rail holding portions 31 may be provided so as to sandwich the car rail 4a as in the present embodiment. As a result, the pair of movable holding portions 31a, 31a pressurize and contact the car rail 4a from both sides, so that the pair of movable holding portions 31a, 31a sandwich the car rail 4a. Therefore, the stop movable portion 16 can be reliably held on the car rail 4a.

The number of rail holding portions 31 for one car rail 4a to 4d is not particularly limited, and may be, for example, two as in this embodiment, or may be, for example, one. Further, the rail holding portions 31 may be provided for all the car rails 4a to 4d, for example, or may be provided for one or some of the car rails 4a to 4d. good.

Here, the operation of the normal stopping mechanism 30 will be described with reference to FIGS. 14 to 16. FIG. Note that the operation of the normal stopping mechanism 30 is not limited to the following operations.

First, as shown in FIGS. 14 and 15, the holding movable portion 31a moves to the holding position at the position where the car 2 is to be stopped on the car rails 4a to 4d. As a result, the holding movable portions 31a, 31a pressurize and contact the car rail 4a, so that the stop movable portion 16 is held by the car rail 4a. Then, the car 2 moves downward while the rail holding part 31 holds the stop movable part 16 on the car rail 4a.

As a result, the stop fixing portion 15 moves downward with respect to the stop movable portion 16, so that the stop movable portion 16 moves toward the stop position. At this time, since the holding restricting portion 31e restricts the holding movable portion 31a positioned at the holding position in the vertical direction D3, the holding movable portion 31a is prevented from moving in the vertical direction D3 with respect to the stop movable portion 16. can do.

Then, as shown in FIG. 16, the stop movable part 16 moves to the stop position. As a result, the movable stop portion 16 and the fixed stop portion 15 cooperate to stop the car 2 on the car rails 4a to 4d. Therefore, the car 2 can be stopped on the car rails 4a to 4c as required.

The operation of the normal stop mechanism 30 may be performed, for example, by manual operation, or may be performed by automatic control by the processing device 5 (see FIG. 1), for example, as in the present embodiment. . For example, as in the present embodiment, the processing device 5 acquires stop instruction information for stopping the car 2 on the car rails 4a to 4d, and the rail holding portion 31 holds the stop movable portion 16 on the car rail 4a. and then move the car 2 downward.

For example, as in the present embodiment, the processing device 5 may acquire the stop instruction information by inputting the stop instruction information to the input unit 6 (see FIG. 1). Further, for example, the processing device 5 may acquire the information of the stop instruction by receiving the information of the stop instruction from the external device.

Next, the configuration of the release device 12 will be described with reference to FIGS. 17 and 18. FIG. Note that the configuration of the release device 12 is not limited to the following configuration.

As shown in FIGS. 17 and 18, the release device 12 includes, for example, a first release portion 32 that is integrated with the movable stop portion 16 and is movable with respect to the fixed stop portion 15, as in the present embodiment, A second release portion 33 whose position is fixed with respect to the hoistway, and a release connection portion 34 that connects the car rail 4a and the second release portion 33 may be provided. Note that the release connection portion 34 may connect the hoistway and the second release portion 33, for example.

The first release portion 32 includes, for example, a first release body portion 32a integral with the stop movable portion 16 and movable with respect to the stop fixed portion 15, and a first release A first release rotating portion 32b is rotatably connected to the tip of the main body portion 32a, and the first release rotating portion 32b is attached to the first release main body portion 32a in a direction in which the tip of the first release rotating portion 32b goes downward. A first rotation restricting portion 32c that restricts rotation with respect thereto may be provided.

Note that the first release body portion 32a may be fixed to the first shaft 14a of the transmission portion 14, for example, as in the present embodiment. As a result, when the first shaft 14a rotates, the stop movable portion 16 and the first release main body portion 32a are moved, so that the stop movable portion 16 and the first release main body portion 32a are integrated to form the stop fixed portion. Move against 15.

Then, for example, as in the present embodiment, when the stop movable portion 16 is positioned at the standby position, the first release portion 32 is inclined with respect to the second horizontal direction D2 so that the tip portion is positioned downward. (see FIG. 17), and the first release portion 32 extends along the second lateral direction D2 (see FIG. 18) when the stop movable portion 16 is positioned at the stop position. good. As a result, the distal end portion of the first release portion 32 is separated from the first shaft 14a in the second lateral direction D2 as the stop movable portion 16 is positioned toward the stop position.

For example, as in the present embodiment, the second release portion 33 may be connected to the release connection portion 34 so as to be rotatable about the shaft portion 33a whose position is fixed with respect to the hoistway. good. For example, as in the present embodiment, the release device 12 includes an upper restricting portion 35 that restricts movement of the distal end portion of the second releasing portion 33 above the upper set position, and the second releasing portion 33. A lower restricting portion 36 that restricts the tip portion from moving below the lower set position may be provided.

The shaft portion 33a may be arranged at the proximal end portion of the second release portion 33, for example, as in the present embodiment. As a result, when the second release portion 33 is separated from the first release portion 32 and no external force is applied to the second release portion 33 , the weight balance of the second release portion 33 causes the second release portion 33 to move. The tip portion is positioned below the shaft portion 33a.

For example, when the second release portion 33 is abutted against the lower restricting portion 36 from below as in the present embodiment, the second release portion 33 is positioned so that the distal end thereof is positioned downward. 2 extends obliquely with respect to the lateral direction D2 (see FIG. 17). It may be configured to extend along D2 (see FIG. 18).

As a result, the tip of the second release portion 33 moves away from the shaft portion 33a in the second lateral direction D2 as the tip portion of the second release portion 33 is positioned upward. Note that, for example, the lower restricting portion 36 does not exist, and the weight balance of the second releasing portion 33b allows the second releasing portion 33 to be inclined with respect to the second horizontal direction D2 so that the tip is positioned downward. It may be configured to extend.

Further, as shown in FIG. 18, for example, when the stop movable portion 16 is positioned at the stop position as in the present embodiment, the second release portion 33 overlaps the first release portion 32 as seen in the vertical direction D3. An overlapping portion 33b may be provided at the tip. Then, as shown in FIG. 17, when the stop movable portion 16 is positioned at the standby position, the overlapping portion 33b may be separated from the first releasing portion 32 as viewed in the vertical direction D3.

For example, when the second release portion 33 is separated from the first release portion 32 as in the present embodiment, the weight balance of the second release portion 33 causes the distal end portion of the second release portion 33 to move toward the shaft portion. Since it is positioned below 33a, overlapping portion 33b may be positioned below shaft portion 33a. Further, for example, the releasing device 12 has an elastic restoring force applied to the second releasing portion 33 so that the overlapping portion 33b is positioned below the shaft portion 33a when the second releasing portion 33 is separated from the first releasing portion 32 . A resilient member (eg, spring) may be provided to apply the force.

The operation of the release device 12 will now be described with reference to FIGS. 17 to 22. FIG. Note that the operation of the release device 12 is not limited to the following operation.

First, when the car 2 is moving at normal speed and acceleration, as shown in FIG. , away from the first release portion 32 in the vertical direction D3. As a result, it is possible to prevent the second release portion 33 from hitting the first release portion 32 , so that the release device 12 does not hinder the movement of the car 2 , for example.

On the other hand, when the car 2 is stopped on the car rails 4a to 4d by the stopping device 11, as shown in FIG. 33b overlaps the first releasing portion 32 as viewed in the vertical direction D3. It should be noted that when the stop movable portion 16 is positioned at the stop position, the car 2 can only move upward. Further, as the car 2 moves upward, the stop movable part 16 may be positioned, for example, slightly below the stop position.

Then, when the car 2 moves upward to the position of the second release portion 33 , the overlapping portion 33 b of the second release portion 33 comes into contact with the first release portion 32 . At this time, the first rotation restricting portion 32c restricts the rotation of the first release rotating portion 32b.

As a result, as the car 2 moves further upward, the first release portion 32 supports the overlapping portion 33b from below as shown in FIG. It rotates around the shaft portion 33a to the position. Therefore, since the overlapping portion 33b moves upward to the upper setting position, the maximum range in which the overlapping portion 33b overlaps with the first release portion 32 increases.

Since the overlapping portion 33b is restricted by the upper restricting portion 35 from moving upward from the upper set position, the first releasing portion 32 moves toward the stop movable portion 16 as the car 2 moves further upward. , and moves relative to the stop fixing portion 15 . Specifically, the stop movable part 16 moves downward with respect to the stop fixed part 15 and moves toward the standby position.

Since the maximum range in which the overlapping portion 33b overlaps with the first releasing portion 32 is increased, the distance that the stop movable portion 16 moves downward is increased. Thereby, for example, as shown in FIG. This facilitates the work of returning the stopping device 11 to the state before the operation.

The operation of the release device 12 may be performed manually, for example, or may be performed automatically by the processing device 5 (see FIG. 1), for example. For example, the processing device 5 moves the car 2 upward to the position of the second release unit 33 by acquiring information of a movement instruction (restoration instruction) to move the stop movable unit 16 downward from the stop position, The stop movable part 16 may be moved to the standby position.

For example, the processing device 5 may acquire the information of the movement instruction by inputting the information of the movement instruction to the input unit 6 (see FIG. 1). Further, for example, the processing device 5 may acquire information on the movement by receiving information on the movement instruction from an external device.

By the way, for example, when the car 2 is moving downward with the stop movable part 16 positioned at or near the stop position, as shown in FIG. Part 33 may be hit. On the other hand, as shown in FIG. 22, the first release rotating portion 32b rotates in a direction in which the tip portion goes upward with respect to the first release body portion 32a.

As a result, it is possible to suppress the first release body portion 32 a from receiving force from the second release portion 33 . Therefore, for example, it is possible to suppress damage to the first and second release portions 32 and 33, and to suppress influence on the operation of the stop movable portion 16, for example. In addition, the first releasing portion 32 may force the first releasing/rotating portion 32b so that the rotated first releasing/rotating portion 32b is returned to the position where the rotation is restricted by the first rotation restricting portion 32c and held there. A resilient member (e.g., a spring) may be provided to apply the force.

Moreover, the number of the second releasing portions 33 with respect to the first releasing portions 32 is not particularly limited. For example, only one second releasing portion 33 may be arranged for one first releasing portion 32 . Specifically, the second release portion 33 may be arranged to contact the first release portion 32 when the car 2 is positioned above the landing on the top floor. As a result, it is possible to prevent the first release portion 32 and the second release portion 33 from coming into contact with each other during normal operation of the car 2 .

Also, the number of releasing devices 12 is not particularly limited. For example, the releasing device 12 may be provided for each of the stop portions 13 (movable stop portion 16), or may be provided for one or a part of the stop portions 13 (movable stop portion 16). may be provided.

As described above, the elevator 1 includes the elevator car device 1a and the car rails 4a to 4d for guiding the car 2, as in the present embodiment.

Then, as in this embodiment, the elevator car system 1a includes a car 2 and a stopping device 11 for stopping the car 2 on the car rails 4a to 4d, and the stopping device 11 is fixed to the car 2. between the stop fixing portion 15, a stop position where the car 2 is stopped on the car rails 4a to 4d in cooperation with the stop fixing portion 15, and a standby position below the stop position. , and a movable stop portion 16 movable with respect to the fixed stop portion 15, further comprising a rail holding portion 31 for holding the movable stop portion 16 on the car rail 4a, is preferable.

According to such a configuration, the movable stop portion 16 moves to the stop position by moving the car 2 downward while the rail holding portion 31 holds the movable stop portion 16 on the car rail 4a. As a result, the movable stop portion 16 and the fixed stop portion 15 cooperate to stop the car 2 on the car rails 4a to 4d. Therefore, the car 2 can be stopped on the car rails 4a-4d as needed.

Further, in the elevator car system 1a, the rail holding portion 31 has a holding position in contact with the car rail 4a to hold the stop movable portion 16 on the car rail 4a, and a retracted position away from the car rail 4a. , and a holding movable portion 31a that is movable with respect to the stop movable portion 16 is preferably provided.

According to such a configuration, the holding movable portion 31a moves between the retracted position and the holding position. When the movable holding portion 31a is positioned at the holding position, the movable holding portion 31a comes into contact with the car rail 4a.

Further, as in the present embodiment, in the elevator car apparatus 1a, the rail holding portion 31 further includes a holding body portion 31b fixed to the stop movable portion 16, and the holding body portion 31b is positioned at the holding position. is preferably provided with a holding restricting portion 31e that restricts movement of the movable holding portion 31a positioned in the vertical direction D3 with respect to the movable stop portion 16. As shown in FIG.

According to such a configuration, the holding movable portion 31a located at the holding position is restricted from moving in the vertical direction D3 with respect to the stop movable portion 16 by the holding restricting portion 31e. As a result, the car 2 moves downward while the movable holding portion 31a is positioned at the holding position, and when the movable stopping portion 16 moves from the standby position to the stopping position, the movable holding portion 31a moves to the movable stopping portion 16. In contrast, movement in the vertical direction D3 can be suppressed.

Further, as in the present embodiment, in the elevator car apparatus 1a, the rail holding portion 31 includes a holding elastic portion 31d that applies an elastic restoring force to the holding movable portion 31a in a direction away from the car rail 4a, and a holding force applying portion 31c that applies a force larger than the elastic restoring force of the elastic portion 31d to the holding movable portion 31a in a direction toward the car rail 4a, wherein the holding elastic portion 31d is the holding movable portion. It is preferable to restore when 31a is at the retracted position.

According to such a configuration, the elastic holding portion 31d applies an elastic restoring force to the movable holding portion 31a in the direction away from the car rail 4a, so that the movable holding portion 31a is positioned at the retracted position. On the other hand, the holding force applying portion 31c applies a force larger than the elastic restoring force of the holding elastic portion 31d to the holding movable portion 31a in the direction toward the car rail 4a, thereby moving the holding movable portion 31a to the holding position. do.

When the movable holding portion 31a is at the retracted position, the elastic holding portion 31d is restored without being elastically deformed. The amount of deformation can be reduced. As a result, the elastic restoring force applied to the movable holding portion 31a by the elastic holding portion 31d can be reduced when the movable holding portion 31a is positioned at the holding position.

The elevator 1 and the elevator car system 1a are not limited to the configurations of the above-described embodiments, nor are they limited to the above-described effects. Further, the elevator 1 and the elevator car system 1a can of course be modified in various ways without departing from the gist of the present invention. For example, it is of course possible to arbitrarily select one or a plurality of configurations, methods, etc., according to various modified examples described below and employ them in the configurations, methods, etc., according to the above-described embodiment.

(1) In the elevator 1 according to the above embodiment, the stationary movable portion 16 is supported by the support portion 21 at the standby position, and the standby position is above the balanced position. be. However, elevator 1 is not limited to such a configuration. For example, the supporting portion 21 may not exist and the standby position of the stationary movable portion 16 may be the balanced position.

(2) In addition, in the elevator 1 according to the above embodiment, the stop force applying portion 23 of the second emergency stop mechanism 18 is configured to apply force to the stop movable portion 16 by pushing the transmission portion 14. . However, elevator 1 is not limited to such a configuration. For example, the stopping force applying part 23 may be configured to apply force to the movable stopping part 16 by directly pushing the movable stopping part 16 without using the transmission part 14 .

(3) Further, in the elevator 1 according to the above embodiment, the first and second car guide portions 9 and 10 are movably connected to the car body portion 8 . However, elevator 1 is not limited to such a configuration. For example, the first and second car guide portions 9 and 10 may be fixed immovably to the car body portion 8 . As an example of such a configuration, the guided portions 9b and 10b may be connected to the car frame 8b.

(4) Further, in the elevator 1 according to the above embodiment, the engagement portion 29 of the second emergency stop mechanism 18 is moved in the second lateral direction D2 by the weight of the second rotating portion 27. be. However, elevator 1 is not limited to such a configuration. For example, as shown in FIGS. 23 and 24, the engagement portion 29 of the second emergency stop mechanism 18 may be moved in the second lateral direction D2 by force applied to the movable stop portion 16. FIG.

Here, the second emergency stop mechanism 18 shown in FIGS. 23 and 24 will be described below.

As shown in FIGS. 23 and 24 , for example, the first rotating portion 25 is arranged so as to sandwich the first stop portion 26 at the first end portion 25 a and is stopped against the first stop portion 26 respectively. The second rotating portion 27 contacts and stops the second end portion 25b of the first rotating portion 25 from the opposite side of the second contact portion 27a. The third stop portion 27e may be provided.

As it moves downward, the operating part 23a and the first rotating part 25 move in the second lateral direction D2 (leftward in FIGS. 23 and 24). As a result, the second abutted portion 25d of the first rotating portion 25 is abutted against the first abutting portion 26, so that the first rotating portion 25 rotates.

Along with this, the third stop portion 27e of the second rotating portion 27 stops the second end portion 25b of the first rotating portion 25, so that the second rotating portion 27 returns to the pre-activation position ( 23 and 24, clockwise). Therefore, the second rotating portion 27 rotates due to the force applied to the stop movable portion 16 (for example, the force applied to the transmission portion 14 by the releasing device 12).

After that, when the second rotating portion 27 hits the engaging portion 29 and the force applied to the second rotating portion 27 is greater than the elastic restoring force of the speed governing elastic portion 22d, the engaging portion 29 moves toward the second lateral Move in direction D2. Then, when the stop movable part 16 moves to the standby position, the second rotating part 27 rotates to the pre-activation position, and the activation part 24 (second emergency stop mechanism 18) is activated without using an electric signal or the like. Automatically restore to previous state.

(5) Further, in the elevator 1 according to the above-described embodiment, the stop force application section 23 is configured to start applying force to the stop movable section 16 when the car 2 moves at the set speed. . However, elevator 1 is not limited to such a configuration. For example, the stop force application part 23 applies a force to the stop movable part 16 when the speed governing part 22e of the speed governing part 22 starts to move, thereby starting the upward movement of the stop movable part 16. The configuration may be such that

(6) Further, in the elevator 1 according to the above embodiment, the starting section 24 is configured to include the first and second rotating sections 25 and 27 .

The holding connecting portion 37c may be configured, for example, to be fixed to the second holding/fixing portion 37b and slidable to the first holding/fixing portion 37a. The movement applying portion 37d may be, for example, an electromagnetic coil that applies an electromagnetic force to the holding connection portion 37c having magnetism. Thus, the moving force adding portion 37d applies force to the holding connection portion 37c when energized, and does not apply force to the holding connection portion 37c when energization is stopped.

25 and 26, as shown in FIG. 25, when the energization of the moving force applying portion 37d is stopped, the holding connection portion 37c is connected to the first holding fixing portion 37a. in the second lateral direction D2. Thereby, the first and second movable body portions 16a, 16a are freely movable in the second lateral direction D2 with respect to the movable connecting portion 16b. Therefore, the first and second movable body portions 16a, 16a are separated from the car rail 4a.

For example, the holding restricting portion 31e may restrict the movement of the holding movable portion 31a in the vertical direction D3 with respect to the stop movable portion 16 only when the holding movable portion 31a is positioned at the holding position. Note that the rail holding portion 31 may not include the holding restricting portion 31e.

(10) In the elevator 1 according to the above-described embodiment, the holding force applying portion 31c that applies a force to the holding movable portion 31a in the direction toward the car rail 4a is an electromagnetic coil, and the holding force applying portion 31c is an electromagnetic coil. The holding elastic portion 31d is a force applying source that applies force to the holding movable portion 31a. However, elevator 1 is not limited to such a configuration. For example, a common device (for example, a linear motor) may be used as a force applying source that applies force to the movable holding portion 31a in both the directions of approaching and separating from the car rail 4a.

(11) Further, in the elevator 1 according to the above embodiment, the release device 12 includes the first release portion 32 movable integrally with the stop movable portion 16 and the first release portion 32 fixed in position with respect to the hoistway. 2 releasing portion 33 is provided. However, elevator 1 is not limited to such a configuration. For example, the release device 12 may be configured to push the rotating members 14c to 14f of the transmission portion 14 to apply a downward force to the movable stop portion 16, thereby moving the movable stop portion 16 downward from the stop position.

(12) Further, in the elevator 1 according to the above-described embodiment, the second release portion 33 is rotatably connected to the release connection portion 34 so as to be rotatable with respect to the hoistway. . However, elevator 1 is not limited to such a configuration. For example, the second release portion 33 may be configured to be fixed to the hoistway by being fixed to the release connection portion 34 .

(13) Further, in the elevator 1 according to the above embodiment, the release device 12 is configured to move the stop movable portion 16 from the stop position to the standby position. However, elevator 1 is not limited to such a configuration. For example, the release device 12 may be configured to move the stop movable portion 16 from the stop position to a position between the stop position and the standby position. Then, the stop movable portion 16 may be configured to be moved to the standby position by manual operation.

(14) In addition, in the elevator 1 according to the above-described embodiment, the first release portion 32 includes the first release body portion 32a movable integrally with the stop movable portion 16, and the base end portion of the first release body portion 32a. A first unlocking rotating portion 32b is rotatably connected to the tip portion of the portion 32a. However, elevator 1 is not limited to such a configuration. For example, as shown in FIGS. 27 to 30, the first release portion 32 may be configured to move together with the movable stop portion 16 as a whole.

(15) Further, in the elevator 1 according to the above-described embodiment, the second releasing portion 33 is configured to rotate as a whole. However, elevator 1 is not limited to such a configuration. For example, as shown in FIGS. 27 to 30, the second release portion 33 includes a second release body portion 33c, a second release rotation portion 33d rotatably connected to the second release body portion 33c, and a second release body portion 33d. A second rotation restricting portion 33e that restricts the rotation of the release rotating portion 33d may be provided.

The release device 12 of FIGS. 27-30 will now be described.

As shown in FIG. 27, the second release portion 33 includes, for example, a second release main body portion 33c that can rotate around a shaft portion 33a whose position is fixed with respect to the hoistway, and a second A second unlocking rotating portion 33d rotatably connected to the tip of the releasing main body portion 33c, and the second unlocking rotating portion 33d moves upward toward the second releasing rotating portion 33c. and a second rotation restricting portion 33e that restricts rotation with respect to.

The overlapping portion 33b may be arranged, for example, in the second release rotation portion 33d. Note that, for example, the entire second release body portion 33c may be fixed immovably to the hoistway by being immovably fixed to the release connection portion 34 . Further, for example, the first release portion 32 may include the first release body portion 32a, the first release rotation portion 32b, and the first rotation restricting portion 32c as in the above-described embodiment.

27, when the car 2 moves upward to the position of the second release portion 33, the overlapping portion 33b of the second release portion 33 hits the first release portion 32. As shown in FIG. At this time, the second rotation restricting portion 33e restricts the rotation of the second release rotating portion 33d.

As a result, the car 2 moves further upward, and as shown in FIG. 27, the second release portion 33 rotates around the shaft portion 33a until it hits the upper restricting portion 35. As shown in FIG. Then, as the car 2 moves further upward, the first release portion 32 moves together with the movable stop portion 16 relative to the fixed stop portion 15 as shown in FIG. 28 . Therefore, the stop movable part 16 moves downward with respect to the stop fixed part 15 and moves toward the standby position.

Further, for example, when the car 2 is moving downward with the stop movable part 16 positioned at or near the stop position, the first release part 32 is moved to the second release position as shown in FIG. Part 33 may be hit. On the other hand, as shown in FIG. 30, the second release rotating portion 33d rotates in a direction in which the tip portion goes downward with respect to the second release body portion 33c.

As a result, it is possible to suppress the second release main body portion 33c from receiving force from the first release portion 32 . In addition, the second release portion 33 may force the second release rotation portion 33d so that the rotated second release rotation portion 33d is returned to a position where rotation is restricted by the second rotation restriction portion 33e and held. A resilient member (e.g., a spring) may be provided to apply the force.

(16) In addition, in the elevator 1 according to the above-described embodiment, the first emergency stop mechanism 17 does not have a mechanism that directly or indirectly stops the stop movable portion 16 and holds it at the standby position. This is the configuration. However, elevator 1 is not limited to such a configuration. For example, the first emergency stop mechanism 17 includes a holding member that directly or indirectly stops the movable stop portion 16 and holds it at the standby position. A configuration in which the holding of the stop movable portion 16 is released when it is moved may also be used.

(17) Further, the elevator 1 according to the above embodiment is configured to include both the first emergency stop mechanism 17 and the second emergency stop mechanism 18 . However, elevator 1 is not limited to such a configuration. For example, the elevator 1 may be configured to have only one of the first emergency stop mechanism 17 and the second emergency stop mechanism 18 .

(18) In the elevator 1 according to the above embodiment, the first emergency stop mechanism 17 is configured to move the stop movable portion 16 to the stop position without using an electric signal. However, elevator 1 is not limited to such a configuration.

For example, the first emergency stop mechanism 17 may use an electrical signal to move the stop movable portion 16 to the stop position. As an example of such a configuration, the first emergency stop mechanism 17 includes a rotation detector (for example, an encoder) that detects rotation of the governor roller 22a. A configuration may also be adopted in which the movable stop portion 16 is moved to the stop position by applying a force to the movable stop portion 16 when the movable stop portion 16 is moved.

(19) Further, in the elevator 1 according to the above embodiment, the second emergency stop mechanism 18 is configured to move the stop movable portion 16 to the stop position without using an electric signal. However, elevator 1 is not limited to such a configuration.
