Description

  The present invention relates to an elevator door device, and more particularly, to an elevator door device provided with a detection means for pinching a long object on one side of a buffer member attached to a door closing side and a door stop side, respectively.

  Conventionally, an elevator door device provided with a detecting means for sandwiching a long object on one side of a cushioning member attached to each of a door closing side and a door contact side, for example, as disclosed in Patent Document 1, It has already been proposed.

JP 7-172745 A

  The configuration disclosed in the above document is provided so that the convex portion and the concave portion of the buffer member form a slight gap so that a detection signal is not output when a long object is not fully sandwiched. . And when a long thing is inserted | pinched, a convex part deform | transforms with a long thing, and the control which opens the door by operating the pressure sensor in it is performed.

  However, it is effective when the sandwiched long object is hard, but when a flexible string-like long object is sandwiched, the string-like elongated object is easily pushed by the convex part of the buffer member and the concave part is easily The pressure sensor may not operate because the force that deforms the convex part is weakened and does not operate, and as a result, there is a risk that the car will move up and down while holding a flexible string-like long object there were.

  An object of the present invention is to provide an elevator door device capable of detecting the pinching of a long stringed object that is not only hard but also a flexible string-like object when the door is closed.

  In order to achieve the above object, the present invention attaches a convex shock-absorbing member having a convex cross section and a concave shock-absorbing member having a concave cross-section to the closed side end and the door-contacting side of the door. When the door is closed, it is deformed by the pressing force of the convex buffer member, and when a long object is pinched locally, a repulsive force generating means for deforming the convex buffer member by generating a repulsive force is provided.

  With this configuration, even when a flexible string-like long object is pinched when the door is closed, a local repulsive force is generated at the position where the repulsive force generating means is pinched, causing the flexible string-like long object to protrude. It can be pushed back to the mold buffer member side, and as a result, the convex buffer member can be deformed to operate the internal detection means. Therefore, not only the long object sandwiched when the door is closed is hard, but also the flexible string-like long object does not escape into the concave groove of the concave buffer member, An elevator door device capable of detecting pinching can be obtained.

  Hereinafter, an elevator door device of the present invention will be described based on a left-right double door for a car shown in FIGS.

  The doors 1A and 1B that open to the left and right sides are hung on the door rail 4 of the frame 3 supported by the fixed member of the car through the door hangers 2A and 2B, and are supported by the fixed member of the same car. It is driven left and right by the door opening and closing device 5.

  Door shoes 6A, 6B are fixed to the lower ends of the doors 1A, 1B, and the door shoes 6A, 6B are engaged and guided by a sill 7 supported by a fixing member.

  On the other hand, as shown in FIG. 2A, the closing side ends of the doors 1A and 1B are respectively provided with a first buffer member 8 made of a rubber material in order to mitigate collision noise and impact when the door is closed. The second buffer member 9 is attached over the entire height.

  The first buffer member 8 is a convex buffer member having a convex cross section, and a sheet-like switch 10 made of, for example, a sheet-like electrode is incorporated inside the protrusion 8A. . When the projection 8A is deformed by pressing, the sheet-like switch 10 is pushed and inserted, and the door opening and closing device 5 is moved from the door closing direction to the door opening direction via a separate control device. Invert.

  The second buffer member 9 is a concave buffer member having a concave cross section, and has a concave groove 9A in which the projection 8A of the first buffer member 8 is accommodated. Then, elastic pieces 9a and 9b that are integral with the second buffer member 9 are formed so as to cover the opening from both sides of the opening of the concave groove 9A. The facing portions of the elastic pieces 9a and 9b are positioned so as to face the protrusion 8A of the first buffer member 8.

  When the doors 1A and 1B having the first buffer member 8 and the second buffer member 9 having the above-described configuration at the door closing side end are normally closed, as shown in FIG. The elastic pieces 9a, 9b of the second buffer member 9 are pushed away by the pressing force in the door closing direction over the entire length in the height direction of the protrusion 8A of the first buffer member 8 disposed along the vertical direction, thereby forming the concave groove 9A. The first buffer member 8 and the second buffer member 9 are brought into close contact with each other in the height direction. As a result, the protrusion 8A of the first buffer member 8 is not deformed, and the built-in sheet-like switch 10 is not operated.

  On the other hand, when the door is closed, as shown in FIG. 2 (c), a flexible string-like long object 11 such as a knitted string of yarn is placed between the first buffer member 8 and the second buffer member 9. If the door is closed and the door closing operation is continued, the long string-like object 11 is pushed by the protrusion 8A of the first buffer member 8 and locally contacts the elastic pieces 9a and 9b of the second buffer member 9. Therefore, a repulsive force is generated there, and the string-like long object 11 is pushed back by the repulsive force so that the protrusion 8A of the first buffer member 8 is deformed. Therefore, the elastic pieces 9a and 9b serve as a repulsive force generating means according to the present invention.

  As a result, the deformation of the projection 8A causes the sheet-like switch 10 built in the rear surface thereof to be deformed and actuate, and the doors 1A and 1B move in the door opening direction via the separate control device and the door opening / closing device 5. Is reversed. Therefore, the car does not move up and down while the string-like long object 11 is sandwiched.

  Thus, when the door is closed, the pinching of the flexible string-like long object 11 can be detected because even if a hard long object is pinched, the elastic pieces 9a and 9b are repelled by the local contact of the hard long object. Is generated, and the repulsive force pushes back a hard long object and deforms the projection 8A of the first buffer member 8 so as to be recessed, so that the detection can be easily performed.

  Incidentally, in the present embodiment, an example in which the elastic pieces 9a and 9b are formed integrally with the second buffer member 9 has been described. However, as shown in FIG. You may make it attach the elastic pieces 9c and 9d of another structure to the both sides of the concave groove 9A of the 2nd buffer member 9 by well-known means, such as adhesion | attachment.

  FIG. 3 shows a first modification of FIG. 2, and the configuration different from the embodiment shown in FIG. 2 is that the opening side of the concave groove 9 </ b> A of the second buffer member 9 is arranged on the second buffer member 9. This is a point that is closed by an elastic film 9e integrated therewith.

  By configuring in this way, when the doors 1A and 1B are normally closed, the protrusion 8A of the first buffer member 8 is an elastic film of the second buffer member 9 as shown in FIG. 9e is pushed away and pushed into the concave groove 9A, and the first buffer member 8 and the second buffer member 9 are brought into close contact with each other in the height direction. As a result, the protrusion 8A of the first buffer member 8 is not deformed, and the built-in sheet-like switch 10 is not operated.

  On the other hand, when the door is closed, as shown in FIG. 3 (c), a flexible string-like long object 11 such as a knitted string of wool is placed between the first buffer member 8 and the second buffer member 9. When the door is closed and the door closing operation is continued, the long string-like object 11 is pushed by the protrusion 8A of the first buffer member 8 and locally contacts the elastic film 9e of the second buffer member 9. A repulsive force is generated there, and the string-like long object 11 is pushed back by the repulsive force so that the protrusion 8A of the first buffer member 8 is deformed. As a result, the deformation of the protrusion 8A activates the sheet-like switch 10 built in the back side thereof, and reverses the movement of the doors 1A and 1B in the door opening direction via the separate control device and the door opening / closing device 5. . Therefore, the car does not move up and down while the string-like long object 11 is sandwiched.

  In the first modification, the example in which the elastic film 9e is formed integrally with the second buffer member 9 has been described. However, as shown in FIG. The elastic film 9f having another configuration may be attached by a known means such as adhesion so as to close the opening of the concave groove 9A of the second buffer member 9.

  FIG. 4 shows a second modification, and a configuration different from that of the embodiment shown in FIG. 2 is a bowl-shape integrated with the second buffer member 9 in the concave groove 9A of the second buffer member 9. The point is that a plurality of elastic bodies 9g are formed.

  With this configuration, when the doors 1A and 1B are normally closed, the protrusion 8A of the first buffer member 8 has a bowl shape of the second buffer member 9 as shown in FIG. The elastic body 9g is pushed away and pushed into the concave groove 9A, thereby bringing the first buffer member 8 and the second buffer member 9 into close contact with each other in the height direction. As a result, the protrusion 8A of the first buffer member 8 is not deformed, and the built-in sheet-like switch 10 is not operated.

  On the other hand, when the door is closed, as shown in FIG. 4 (c), a flexible string-like long object 11 such as a knitted string of yarn is placed between the first buffer member 8 and the second buffer member 9. When the door is closed and the door closing operation is continued, the long string-like object 11 is pushed by the protrusion 8A of the first buffer member 8 and locally comes into contact with the hook-shaped elastic body 9g of the second buffer member 9. Therefore, a repulsive force is generated there, and the string-like long object 11 is pushed back by the repulsive force so that the protrusion 8A of the first buffer member 8 is deformed. As a result, the deformation of the protrusion 8A activates the sheet-like switch 10 built in the back side thereof, and reverses the movement of the doors 1A and 1B in the door opening direction via the separate control device and the door opening / closing device 5. . Therefore, the car does not move up and down while the string-like long object 11 is sandwiched.

  Also in the second modified example, as shown in FIG. 4 (d), the hook-shaped elastic body 9h having a configuration different from that of the second buffer member 9 is attached to the second buffer by a known means such as adhesion. You may make it attach in the concave groove 9A of the member 9. FIG.

  Further, FIG. 5 shows a third modification. A configuration different from the embodiment shown in FIG. 2 is that a flexible elastic material 9i such as a sponge is placed in the concave groove 9A of the second buffer member 9. It is a buried point.

  With this configuration, when the doors 1A and 1B are normally closed, the protrusion 8A of the first buffer member 8 is flexible and elastic of the second buffer member 9, as shown in FIG. The material 9i is pushed away and pushed into the concave groove 9A, and the first buffer member 8 and the second buffer member 9 are brought into close contact with each other in the height direction. As a result, the protrusion 8A of the first buffer member 8 is not deformed, and the built-in sheet-like switch 10 is not operated.

  On the other hand, when the door is closed, as shown in FIG. 5C, a flexible string-like long object 11 such as a knitted string of yarn is placed between the first buffer member 8 and the second buffer member 9. If the door is closed and the door closing operation is continued, the long string-like object 11 is pushed by the protrusion 8A of the first buffer member 8 and locally contacts the flexible elastic material 9i of the second buffer member 9. A repulsive force is generated there, and the long string-like object 11 is pushed back by the repulsive force so that the protrusion 8A of the first buffer member 8 is deformed. As a result, the deformation of the protrusion 8A activates the sheet-like switch 10 built in the back side thereof, and reverses the movement of the doors 1A and 1B in the door opening direction via the separate control device and the door opening / closing device 5. . Therefore, the car does not move up and down while the string-like long object 11 is sandwiched.

  As described above, according to the embodiment and each modification according to the present invention, not only the long object sandwiched when the door is closed is hard, but also the flexible buffer-like long object can A flexible string-like long object does not escape into the concave groove, and an elevator door device that can detect the pinching can be obtained.

  In the above-described embodiments and modifications, the elevator door device has been described based on the left and right double doors. Needless to say, the present invention can also be applied to an elevator door device having a single door. . In that case, what is necessary is just to apply the door stop structure of the door of one side in the said embodiment and each modification to the door stopper pillar of the door stop side of a single door.

  Moreover, although the said embodiment and each modification demonstrated the door of the passenger car, you may apply also to the door on the landing side.
