Description

  The present invention relates to a holder opening fixing device for fixing the position of a holder that freely moves on a hall sill (hall sill) in an elevator in an open state. The present invention relates to a hold door opening and fixing device capable of reducing a burden.

  Conventionally, an elevator hall has been provided with a hold door, and when the car arrives, the hold door is opened and closed in conjunction with the opening and closing of the car side door. By the way, when performing maintenance and inspection work of the elevator, it is necessary to open the hold door alone in order to perform work on the upper part of the car or inside the hoistway. At this time, the holder is provided with a self-closing mechanism for maintaining the closed state. Therefore, when releasing the holder, the holder is opened against the urging force in the closing direction by the self-closing mechanism. It is necessary to fix the position to the state.

  Therefore, conventionally, various types of holder opening and fixing devices are used to fix the position of the holder that moves freely on the hall sill (hole sill) in the open state. Specifically, conventionally, a method of fixing the holder in the open state by driving a wedge-shaped stopper between the upper surface of the landing sill that guides the opening and closing of the holder and the lower surface of the holder is used. It was done.

  As another method, as disclosed in Patent Document 1, the installation to the hall and the operation of fixing the position of the hold door to the open state are easy, and the position of the hold door can be reliably fixed to the open state. An improved hold door opening and fixing device is known.

JP 2004-224466 A

However, when using the conventional holder opening and fixing method as described above, the operator must perform an operation of fixing the position of the holder in the open state in the vicinity of the landing threshold. Thus, when performing maintenance and inspection work on the elevator, the worker rides on the upper surface of the car and performs the maintenance and inspection work, so the worker on the upper surface of the car fixes the position with the hold door open. In order to do this, it is necessary to go down to the hall from the upper surface of the car, fix the hold door in an open state with a stopper or the like, and then return to the upper surface of the car again, which is a heavy burden on the operator. It was.
In addition, when a wedge-shaped stopper is driven between the upper surface of the landing sill and the lower surface of the hold door, a metal one is generally used as this stopper, so that the landing threshold or the hold door is scratched. There was a risk of it. Moreover, when using such a stopper, both hands of the operator may be blocked and the posture may become unstable.

  The present invention has been made in consideration of such points, and an object of the present invention is to provide a holder opening fixing device that can reduce the burden on the operator in fixing the position of the holder in the open state. To do.

  The present invention relates to an elevator holder opening fixing device for fixing a holder that moves freely on a landing sill in an open state, the fixing member provided in the vicinity of the landing sill, and the fixing member Is attached, and the rear surface of the hold door (the hoistway side) so that the fixing member is movable between a fixing position where the fixing member comes into contact with the landing sill and a retreating position where the fixing member retracts from the landing sill. And when the operation member is in the fixed position, the position of the hold door is fixed by a static friction force acting between the fixing member and the landing sill. This is an elevator hold-a-release fixing device.

  According to such a hold door opening and fixing device, even if the worker is not on the landing sill, such as when the worker is performing maintenance on the upper surface of the car, the operation member installed on the back surface of the hold door As a result of the operation, the fixing member can be brought into contact with the landing sill and the position of the hold door can be fixed by the static friction force. For this reason, in order to fix the position of the hold door in the open state, for example, the worker on the upper surface of the car does not have to bother to get down to the landing threshold, and the burden on the worker can be reduced.

  In the hold door opening and fixing device of the present invention, a holding member that detachably holds the operation member so as to maintain the operation member in the retracted position is attached to the back surface of the hold door, It is preferable to be configured to move to the fixed position when released from being held by the holding member. As a result, an operator on the upper surface of the car can move the operating member simply by operating the holding member attached to the rear surface of the hold door, and the work for fixing the position of the hold door. Can be performed more easily.

  In the hold door opening and fixing device of the present invention, it is preferable that the holding member is attached to an upper half region of the hold door. Thus, even when the upper surface of the car is at a position higher than the landing threshold, the operator on the upper surface of the car can easily operate the holding member.

  In the hold door opening and fixing device of the present invention, it is preferable that the fixing member is made of an elastic material. By this, it is possible to generate a sufficiently large static friction force between the fixing member and the landing threshold, and to prevent the landing threshold from being damaged when the fixing member is brought into contact with the landing threshold. Can do.

  According to the hold door opening and fixing device of the present invention, it is possible to reduce the burden on the operator in fixing the position of the hold door in the open state.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic configuration diagram showing an embodiment of a hold door opening and fixing device according to the present invention incorporated in an elevator.

The elevator holder 11 is configured to freely move in the left-right direction in FIG. Specifically, a pair of left and right hanger rollers 18 are pivotally supported by a shaft portion 18a on the upper portion of the holder 11, and these hanger rollers 18 are guided in the left-right direction in FIG. It is like that. Further, a door rope fixing portion 20 is provided on the upper surface of the hold door 11, and a door weight 16 is connected to the door rope fixing portion 20 via a door rope 17. Due to the weight of the door weight 16, the door rope fixing portion 20 can be moved in the right direction in FIG. 1. When no force is applied to the hold door 11, the hold door 11 is the most in the landing threshold 15. It exists in the right position.
The door weight 16, the door rope 17, the door rope fixing portion 20, the hanger roller 18, the door rail 19, and the like constitute a self-closing mechanism for maintaining the closed state of the hold door 11.

  A pair of left and right door guide shoes 14 are provided on the bottom surface of the hold door 11. Further, the landing sill 15 is provided with a groove 15a along the left-right direction of FIG. 1, and the pair of left and right door guide shoes 14 are respectively fitted into the groove 15a. As a result, the door guide shoe 14 is guided along the direction in which the groove 15a extends (the left-right direction in FIG. 1).

In fixing the position of the holder 11 in the open state, the fixing member 13 provided in the vicinity of the landing threshold 15, the operation member 12 having the fixing member 13 attached to one end, and the operation member 12 are held. A holding door opening and fixing device including a holding member 23 is used. The operation member 12, the fixing member 13, and the holding member 23 are installed on the back surface (the hoistway side) of the hold door 11. Reference numeral 30 in FIG. 1 indicates a car, and a state in which an operator is on the upper surface of the car 30 is indicated by a dotted line portion in FIG.
Hereinafter, the details of each component of such a holder opening and fixing device will be described.

  As shown in FIG. 1, the operating member 12 includes a shaft portion 12a attached to the upper half region of the back surface (the hoistway side) of the hold door 11, and a first end rotatably supported by the shaft portion 12a. Rod portion 12b, a shaft portion 12c provided at the other end of the first rod portion 12b, a second rod portion 12d rotatably supported at one end by the shaft portion 12c, and a second rod portion And a connecting portion 12e provided at the other end of 12d. In the shaft portion 12a, for example, a torsion coil spring (not shown) is provided between the holder 11 and the first rod portion 12b, and the first rod portion 12b is centered on the shaft portion 12a by the torsion coil spring. As shown in FIG. 1, when a force is applied in the clockwise direction and no external force is applied to the first rod portion 12b, the first rod portion 12b extends in the downward direction. Further, in the shaft portion 12c, for example, a torsion coil spring (not shown) is provided between the first rod portion 12b and the second rod portion 12d, and the second rod portion 12d is also formed by this torsion coil spring. When a force is applied clockwise about the shaft portion 12c in FIG. 1 and no external force is applied to the second rod portion 12d, the second rod portion 12b is perpendicular to the first rod portion 12a. It extends in the downward direction.

  The operation member 12 is shown by a solid line portion in FIG. 1 when no external force is applied to the first rod portion 12b and the second rod portion 12d because the torsion coil springs are provided on the shaft portions 12a and 12c, respectively. It exists in such a position.

  The fixing member 13 has a rod portion 13b whose central portion is supported by the connection portion 12e of the operation member 12, and a stopper portion 13a provided at one end of the rod portion 13b. The rod portion 13b is connected to the second rod portion 12d of the operation member 12 in a fixed state via the connection portion 12e. Specifically, as shown in FIG. 1, the bar portion 13b has a central portion connected to the connecting portion 12e, and extends obliquely downward from a portion connected to the connecting portion 12e. A substantially rectangular parallelepiped stopper portion 13a made of an elastic material such as a hard rubber material is attached to the lower end of the first rod portion 13b.

  The holding member 23 has a function of detachably holding the first rod portion 12b of the operation member 12. Specifically, the holding member 23 is attached to the back surface of the hold door 11 at substantially the same height level as the shaft portion 12a of the operation member 12, and is positioned in the vicinity of the shaft portion 12a. The holding member 23 is configured to be able to detachably hold the first rod portion 12 b of the operation member 12. When the first rod portion 12 b is held by the holding member 23, the holding member 23 is operated. The member 12 exists at a position as shown by a two-dot chain line portion in FIG. Attachment / detachment of the first rod portion 12b by the holding member 23 can be performed manually by an operator.

  Next, the operation of the holder opening fixing device of the present embodiment having such a configuration will be described.

The operation member 12 of the holder opening fixing device is movable between a retracted position as shown by a double chain line portion in FIG. 1 and a fixed position as shown by a solid line portion in FIG. Specifically, during normal operation of the elevator, the first rod portion 12b of the operating member 12 is held by the holding member 23 as shown by the double chain line portion in FIG. The stopper portion 13 a of the fixing member 13 fixed by the portion 12 e is separated from the landing threshold 15.
In this case, since the movement of the hold door 11 in the left-right direction is not restricted, the door rope fixing portion 20 is pulled in the right direction in FIG. The door 11 is also moved rightward, and the holder 11 is in a so-called “closed” state at the right end of the landing threshold 15.

  On the other hand, for example, when an operator is performing maintenance on the upper surface of the car 30, if the hold door 11 needs to be left open, that is, the hold door 11 is moved to the left in FIG. 1, the operator first moves the holder 11 to the left side of FIG. 1 for example, and then the operator moves the holder 11 in a state where the holder 11 is moved. The first rod portion 12 b of the operation member 12 is released from the holding member 23. As a result, the operation member 12 is moved to a position as shown by a solid line in FIG. 1 by the action of the torsion coil springs provided on the shaft portions 12a and 12c.

  In the state shown in FIG. 1, due to the action of the torsion coil spring provided on the shaft portion 12c, the second rod portion 12d receives a force that can be further rotated clockwise about the shaft portion 12c in FIG. It becomes. Therefore, a downward force is also applied to the stopper portion 13a of the fixing member 13 provided at the lower end of the second rod portion 12d, and the stopper portion 13a presses the surface of the landing sill 15. Since the stopper portion 13a is formed of an elastic material such as a hard rubber material, when a downward force is applied to the stopper portion 13a, a static friction force acts between the stopper portion 13a and the landing sill 15, The position of the hold door 11 is fixed by the static friction force.

  As described above, according to the hold door opening and fixing device of the present embodiment, the operation member 12 to which the fixing member 13 is attached has the fixing position at which the fixing member 13 abuts the landing threshold 15 and the fixing member 13. It is installed on the back surface (the hoistway side) of the holder 11 so as to be movable between a retreat position where it retreats from the landing sill 15, and when the operation member 12 is in a fixed position, the fixed member 13 and the landing The position of the hold door 11 is fixed by a static friction force acting between the sill 15. Therefore, even when the worker is not on the landing sill 15 such as when the worker is performing maintenance on the upper surface of the car 30, by operating the operation member 12 installed on the back surface of the hold door 11. The holding member 11 can be fixed in position by the static friction force by bringing the fixing member 13 into contact with the landing threshold 15. For this reason, in order to fix the position of the hold door 11 in the open state, for example, an operator on the upper surface of the car 30 does not have to bother to get down to the landing sill 15, and the burden on the operator can be reduced.

  A holding member 23 that detachably holds the operation member 12 is attached to the back surface of the hold door 11 so as to maintain the operation member 12 in the retracted position. The operation member 12 is released from being held by the holding member 23. Since it is formed to move to a fixed position when it is operated, an operator on the upper surface of the car 30 simply operates the holding member 23 attached to the back surface of the hold door 11 to move the operation member 12. As a result, the work for fixing the position of the hold door 11 can be performed more easily.

  Further, since the holding member 23 is attached to the upper half area of the hold door 11, even if the upper surface of the car 30 is higher than the landing threshold 15 as shown in FIG. An operator on the upper surface of 30 can easily operate the holding member 23.

  Further, since the fixing member 13 has a stopper portion 13a made of an elastic material such as a hard rubber material, a sufficiently large static friction force can be generated between the fixing member 13 and the landing sill 15, It is possible to prevent the landing threshold 15 from being damaged when the fixing member 13 is brought into contact with the landing threshold 15.

It should be noted that the hold door opening and fixing device according to the present invention is not limited to the above embodiment, and various modifications can be made.
For example, the operation member is not limited to the first rod portion 12b and the second rod portion 12d as shown in FIG. 1, and the fixing member 13 is fixed so as to contact the landing sill 15. As long as it is installed on the hoistway side of the holder 11 so as to be movable between the position and the retreat position where the fixing member 13 retreats from the landing threshold 15, other configurations may be used. Good.
