Description

  The present invention relates to an elevator apparatus and an elevator door apparatus that can detect that a string-like long foreign object is caught in an elevator door.

  In general, when an object is sandwiched in a door, a foreign object detection rod called a safety shoe is pushed into the door to detect the foreign object, and the door is controlled to stop or reverse. Safety function is provided. However, when a string-like flexible long foreign object is caught in the door, the safety shoe cannot be fully pushed in to detect the foreign object, and the car may move with the long foreign object held in the door. Was assumed.

  Therefore, conventionally, along the height direction of the door-end side end portion of the door, one side is opened, and a buffer member incorporating a pressure detection body and a base member serving as a foundation thereof is provided, and a string sandwiched between the doors There has been proposed one that can detect a flexible, long, foreign object (for example, see Patent Document 1).

JP 2008-143619 (paragraph numbers 0022 to 0026, FIG. 2)

  However, the above-described one is formed of a pressure detector having a circular cross-sectional shape along the height direction of the door-contact side end portion of the door, and, for example, a metal flat plate, and the pressure detector is disposed on the counterdoor-side The pressure detecting body and the base member are in a line contact state, and the base member has a predetermined hardness but is supported by a flexible buffer member. For this reason, when a long foreign object is sandwiched between the doors, the base member is deformed and displaced by a small amount due to local pressure applied by the pressure detection body, and thus the pressure detection body is also displaced. There has been a problem that the sensitivity of detecting foreign matter is reduced. Further, the pressure detection body and the base member are extended along the height direction of the door-contact side end of the door, and as shown in FIG. The screw is not arranged so as to support the base member, and this problem becomes significant at a position where the opposite side of the base member is a gap.

  The present invention has been made from the actual situation in the above-described prior art, and an object thereof is to provide an elevator apparatus and an elevator door apparatus capable of improving the foreign matter detection sensitivity.

In order to achieve the above object, the present invention provides a cushioning member in which a pressure detector is disposed at a door contact portion of a door that opens and closes in a lateral direction with an upper portion guided by a door rail and a lower portion guided by a sill parallel to the door rail. In the elevator door device that controls stop or reverse of the door according to foreign object detection, the buffer member has a first flat surface at the center portion along the depth direction of the door door end side. And a second flat surface that is mounted so as to cover the base member and that faces the first flat surface of the base member on the back surface of the central portion along the depth direction of the door door end side portion. And a flat plate-shaped pressure detector between the first flat surface and the second flat surface, and the base member and the cover member. Each flexed Thereby forming a member, said cover member comprises a flexure resistance of deformation with less pressure than the base member, the end portion of the base member, provided with a locked portion, the end portion of the cover member, the The cover is provided with a locking portion that is locked to the locked portion, and the pressure detection body is disposed between the first flat surface of the base member and the second flat surface of the cover member. The base member is mounted so as to be rolled up by a member, and the locking portion of the cover member is locked to the locked portion of the base member .

In the present invention configured as above, the buffer member is divided into the base member and the cover member, and a flat plate-shaped pressure detection is provided between the first flat surface of the base member and the second flat surface of the cover member. When the body is arranged and a long foreign object is sandwiched between the doors, the pressure detection body supported by the base member is reliably deformed by surface contact so as to detect the foreign object. Further, by forming the cover member with a relatively soft flexible member, the pressure when the foreign object is sandwiched can be reliably transmitted to the pressure detection body, and the base member is formed with a relatively hard flexible member. This prevents the pressure transmitted to the pressure detector from escaping. As a result, the foreign matter detection sensitivity can be improved. In addition, by locking the locking portion of the cover member to the locked portion of the base member, the cover member is firmly engaged with each other and protrudes from the door door side end portion, and is a relatively soft flexible member. Even when the cover member formed in (1) collides with a carriage or the like, it is possible to prevent the cover member from being detached from the base member and protruding from the door door side end portion or falling off.

The present invention also includes a car that moves up and down the hoistway, and a door that opens and closes when the passenger gets in and out of the car. The door is guided by a door rail at the top and a sill parallel to the door rail at the bottom. In an elevator apparatus that is provided with a buffer member having a pressure detector disposed at a door contact portion of the door that opens and closes in the lateral direction, and that controls stop or reverse of the door in accordance with foreign object detection, the buffer member is a door A base member having a first flat surface in the center portion along the depth direction of the door-end side end portion, and a center portion along the depth direction of the door door end-side end portion mounted so as to cover the base member The back member is divided into a cover member having a second flat surface facing the first flat surface of the base member, and between the first flat surface and the second flat surface.

It is characterized by being locked .

  In the present invention configured as above, the buffer member is divided into the base member and the cover member, and a flat plate-shaped pressure detection is provided between the first flat surface of the base member and the second flat surface of the cover member. When the body is arranged and a long foreign object is sandwiched between the doors, the pressure detection body supported by the base member is reliably deformed by surface contact, and the elevator apparatus can detect the foreign object. Further, by forming the cover member with a relatively soft flexible member, the pressure when the foreign object is sandwiched can be reliably transmitted to the pressure detection body, and the base member is formed with a relatively hard flexible member. This prevents the pressure transmitted to the pressure detector from escaping. Thereby, the elevator apparatus which can aim at the improvement of a foreign material detection sensitivity can be provided.

It is a front view of the door of the elevator with which this invention is applied. 1 shows an embodiment of an elevator door device according to the present invention, and is a cross-sectional view taken along line AA of a door door contact portion in FIG. 1. It is the FIG. 2 equivalent view which shows the other Example of the door apparatus of the elevator which concerns on this invention. 1 is a diagram showing an overall outline of an elevator apparatus according to the present invention.

  Embodiments of an elevator door device according to the present invention will be described below with reference to the drawings.

  FIG. 4 is a diagram showing an overall outline of the elevator apparatus according to the embodiment of the present invention. As shown in the figure, an elevator apparatus 100 in this embodiment drives a car 101 and a counterweight 102 that move up and down in a hoistway 110, and a rope 103 and a rope 103 that suspend the car 101 and the counterweight 102. Thus, a hoisting machine 104 that drives the car 101 and the counterweight 102 in the vertical direction of the hoistway 110 is provided. A sheave 105 is attached to the hoisting machine 104, and the rotational torque of the sheave 105 is transmitted to the rope 103 by the frictional force generated between the rope 103 and the sheave 105, and the counterweight 102 is counterbalanced with the car 101 via the rope 103. Moves.

  As shown in FIG. 1, elevator doors 1a and 1b are hung on a door rail 4 installed on a door rail frame 3 by hangers 2a and 2b, and hanger rollers 5a, 5b, 5c and 5d roll on the door rail. It can be opened and closed freely and is driven to open and close by a motor (not shown). Guide shoes 6a and 6b are attached to the lower part of the doors 1a and 1b, and can be opened and closed while the doors 1a and 1b are kept vertical by sliding smoothly in the grooves provided in the sill 7. I have to. Further, door joints 8a and 8b are attached in the door height direction to the door contact side ends of the doors 1a and 1b, and buffer members 9 and 10 are provided from the inside of the door joints 8a and 8b to the door contact side.

  As shown in FIG. 2, the buffer member 9 has a convex contact surface, and the buffer member 10 has a concave door contact surface.

  The buffer member 9 includes a base member 9a provided with a first flat surface 9a1 at a substantially central portion along the depth direction (door thickness direction, the same applies hereinafter) of the door door side end portion, and the base member 9a. The cover member 9b is mounted so as to cover and is provided with a second flat surface 9b1 facing the first flat surface 9a1 of the base member 9a on the back surface of the central portion along the depth direction of the door door side end portion. In addition, a flat plate-shaped pressure detector 11 is disposed between the first flat surface 9a1 and the second flat surface 9b1. Further, the base member 9a and the cover member 9b are each formed of a flexible member, for example, a resin, and the cover member 9b has a flexibility that deforms with less pressure than the base member 9a. Furthermore, a locked portion 9a2 is provided at the end of the base member 9a, and a locking portion 9b2 for locking to the locked portion 9a2 is provided at the end of the cover member 9b. Furthermore, the width dimension on the depth side of the base portion 9a is set to be larger than the width dimension of the opening portion on the door contact side of the door joint 8a.

  In the present embodiment, in the divided buffer member 9, the pressure detector 11 is disposed between the first flat surface 9a1 of the base member 9a and the second flat surface 9b1 of the cover member 9b. Thus, the cover member 9b is mounted so that the base member 9a is wound, and the locking portion 9b2 of the cover member 9b is locked to the locked portion 9a2 of the base member 9a. Basically, the base member 9a and the cover member 9b can be assembled without using a double-sided tape or an adhesive. However, the relative position of the base member 9a and the cover member 9b can be changed during assembly or during use. If they are misaligned, they can be assembled by fixing them using a double-sided tape or an adhesive. Further, when the position of the pressure detection body 11 is shifted when the base member 9a and the cover member 9b are assembled, the pressure detection body 11 is attached to at least one of the base member 9a or the cover member 9b with a double-sided tape or the like. Workability is improved by temporarily fixing. The buffer member 9 assembled in this way is inserted into the door joint 8a as shown in FIG.

  By locking the locking portion 9b2 of the cover member 9b to the locked portion 9a2 of the base member 9a and inserting the buffer member 9 into the door joint 8a, the cover member 9b sandwiches the base member 9a, The engagement between the base member 9a and the cover member 9b is strong. As a result, even when a carriage or the like collides with the protruding portion of the cover member 9b protruding from the door joint 8a so as to be rubbed from the side surface, the cover portion 9 material 9b protrudes from the door joint 8a or falls off. There is no. Further, the base member 9a is formed of a resin having a predetermined hardness, and the width dimension on the depth side is set larger than the width dimension of the door-side opening portion of the door joint 8a, whereby the base member 9a is formed. Also, it does not protrude from the door joint 8a or fall off.

  When a foreign object, for example, a string-like long foreign object is sandwiched between the doors 1a and 1b, the contact pressure acting on the door contact side according to the door closing operation with the foreign object sandwiched is applied via the cover member 9b. This is transmitted to the pressure detector 11. At this time, the pressure detection body 11 supported by the base member 9a is reliably deformed by the surface contact, and the foreign matter is detected. Further, since the cover member 9a is formed of a relatively soft resin, the pressure when the foreign object is sandwiched is reliably transmitted to the pressure detector 11, and the base member 9a is formed of a relatively hard resin. This prevents the pressure transmitted to the pressure detector 11 from escaping. In this way, the pressure detection body 11 is deformed by the contact pressure, and a detection signal is output in response to the electrodes inside the pressure detection body 11 touching, preventing the elevator from moving and opening the doors 1a and 1b again. Let

  According to the present embodiment, the foreign matter detection sensitivity can be improved, that is, the string-like long foreign matter sandwiched between the doors 1a and 1b can be reliably detected, and the safety of the elevator can be improved. In addition, the locking portion 9b2 of the cover member 9b is locked to the locked portion 9a2 of the base member 9a so that they are firmly engaged with each other and protrude from the door joint 8a. Even when the cover member 9b formed of a member collides with a carriage or the like, it is possible to prevent the cover member 9b from being detached from the base member 9a and protruding from the door joint 8a or falling off.

  In the above-described embodiment, the example in which the buffer member 9 provided with the pressure detector 11 is mounted on the door joint 9a of the door 1a is shown. However, in the case of a double door, the buffer member 9 provided with the pressure detector 11 is provided. Either the left or right door may be installed, and the buffer member 10 may be attached to the door facing the door on which the buffer member 9 is installed. Moreover, in the case of a single door, the buffer member 9 is installed on either the door or the door-to-car pillar, and the buffer member 10 is installed on the other side. Further, the buffer members 9 and 10 may be attached not only to the car doors 1a and 1b but also to the landing doors. In this embodiment, the base member 9a and the cover member 9b are formed of resin. However, the present invention is not limited to this, and the base member 9a and the cover member 9b are made of other flexible members such as rubber. May be formed.

  Here, based on FIG. 3, the example which attaches the buffer members 9 and 10 directly to the door stop part of the doors 1a and 1b, without using the door joints 8a and 8b is demonstrated.

  In another embodiment, as shown in FIG. 3, the buffer members 9 and 10 are continuous from the design surfaces of the doors 1a and 1b and are bent to be orthogonal to each other. Part 21 and the back of door 1a, 1b, 2nd door stop part 22 arrange | positioned so as to oppose the 1st door stop part 21, and the back surface of the board | plate material which comprises a design surface It is inserted into a storage space 24 formed by a base 23 having a U-shaped cross section. That is, by fixing the buffer members 9 and 10 to the base portion 23 so as to form the storage space 24 using the second door stop portion 22 in contact with the base portion 23, the door joint described above is obtained. The buffer members 9 and 10 are fixed in the same manner as that using 8a and 8b. The base 23 is fixed to the back surface of the doors 1a and 1b by means such as an adhesive or welding. Here, the 2nd door stop part 22 is fixed to the base part 23 with the fastening members 25, such as a screw | thread, so that the buffer members 9 and 10 can be replaced | exchanged.

  Thus, even if it is the structure which attaches the buffer members 9 and 10 to the storage space 24 of the door stop part of the doors 1a and 1b without using the door joints 8a and 8b, the structure of the buffer members 9 and 10 is changed. There is no need. That is, the cushioning members 9 and 10 have high generality, and can be applied to elevators of all specifications.

  In the present embodiment, the door to which the buffer member 9 is attached may be applied to either the car door of the car 101 of the elevator apparatus 100 or the landing door provided on the floor on which the car 101 is landed. However, it may be applied to both.
