Description

  The present invention relates to an elevator apparatus in which a car traveling in a hoistway provided in a building or the like moves up and down, and more particularly to an elevator apparatus that suppresses vibration of the car.

  In an elevator, if there is a change in the load, such as when a passenger gets on and off, while the car is stopped, the car may vibrate up and down softly. This phenomenon is caused by, for example, expansion and contraction of the main rope in the rope type elevator, but gives passengers anxiety. Various measures have been considered to suppress this vibration. In the case of a rope type elevator, using a main rope with high rigidity is one measure, but considering the wear of the rope itself and the hoisting device, it is not possible to use a main rope with excessively high rigidity. Can not. Patent Document 1 discloses a method in which when a car is stopped and a door is fully opened, a fixing device is actuated by a command from a control device, and a car frame is fixed to a guide rail provided in a hoistway. Is disclosed. However, this method has a problem that it requires a complicated fixing device and complicated control. The elevator apparatus disclosed in Patent Document 2 includes a speed sensor that detects the speed of the car frame and an acceleration sensor that detects the acceleration of the car room, and the direction of the speed of the car frame is the acceleration of the car room. By reducing the speed of the car frame by applying braking force to the rotation of the guide roller when the direction is opposite to the direction, an inertia force opposite to the car room acceleration is generated to reduce the car room acceleration. doing. This method has many problems and requires complicated control.

  Hereinafter, an embodiment as an example of the present invention will be described as appropriate with reference to the drawings. Note that the same reference numerals denote the same parts even in different drawings. First, the case where some members of the engagement mechanism used in the elevator apparatus are used in one embodiment of the present invention will be described. FIG. 1 is a view for explaining an engaging member provided on a door (car door) of a car room housed in a car frame, and is a view of the car as seen from the landing side outside the hoistway. It is. In FIG. 1, so-called side-opening double door double door type car doors 102 and 104 are shown. However, the present invention does not depend on the double-opening method or the single-opening method, and does not depend on the number of doors. When it is confirmed that the car has arrived at the landing floor and stopped, the car doors 102 and 104 are included in the car door driving unit 108 provided in the car via the car door belt 106. It opens and closes in conjunction with the power of a car door motor (not shown). The car door 102 is provided with a car door side engaging portion 110 that transmits the movement of the car door 102 to a landing door provided on the landing floor.

  FIG. 2A is an enlarged view of the portion including the car door side engaging portion 110 in FIG. The car door side engaging portion 110 includes two link members 202 and 204. The link members 202 and 204 are pivotally attached to the plate 206 fixed to the car door 102 by means of fixing members 208 and 210, respectively. The fixing members 208 and 210 are arranged so that their centers are on a straight line in the ascending / descending direction. The two link members 202 and 204 are respectively connected to the first engaging blade 216 by connecting portions 212 a and 212 b on the closing direction side of the car door 102, and connecting portions 214 a on the opening direction side of the car door 102. 214b are connected to the second engagement blade 218, respectively. The first engagement blade 216 and the second engagement blade 218 are disposed in parallel with the elevator car's ascending / descending direction. Further, as shown in FIG. 2A, the two link members 202 and 204 are in a plane parallel to the car door 102, and are connected to the first engagement blade 216 and the second engagement blade 218. For example, it is disposed obliquely. Since the first engagement blade 216 and the second engagement blade 218 and the link members 202 and 204 are connected as described above, for example, when a force that pushes down the first engagement blade 216 is applied, Since the connecting portions 212a and 212b move downward and the connecting portions 214a and 214b move upward via the link members 202 and 204, the second engagement blade 218 moves upward. In this case, since the first engagement blade 216, the second engagement blade 218, and the link members 202 and 204 are connected, the car door of the first engagement blade 216 and the second engagement blade 218 is connected. The interval in the opening / closing direction of 102 changes. This interval is narrowed when connected in the form as shown in FIG.

  As described above, the car door 102 is opened and closed by the power of a car door motor (not shown) included in the car door driving unit 108 provided on the car via the car door belt 106. A hanger rail 222 is fixed to the door header 220 of the car room above the car door 102 in parallel to the opening / closing direction of the car door. Car door suspension members 224a and 224b are fixed above the car door 102, and car door rollers 226a and 226b are provided above the car door suspension members 224a and 224b, respectively. The car door rollers 226 a and 226 b move on the hanger rail 222. That is, the car door 102 opens and closes while being hung on the hanger rail 222 via the car door rollers 226a and 226b and the car door suspension members 224a and 224b. Similarly, the car door 104 opens and closes in conjunction with the car door 102 while being hung on the hanger rail 222 via the corresponding car door roller and the car door suspension member.

  A car door side engagement blade roller 228 is provided on the upper portion of the first engagement blade 216. An engagement blade roller guide member 230 is fixed to the door header 220 of the car compartment substantially parallel to the opening / closing direction of the car door 102. For example, the first engagement blade 216 is biased upward with an appropriate force, or the second engagement blade 218 is biased downward with an appropriate force. The joint blade 216 tries to move upward, but when the car door side engagement blade roller 228 contacts the engagement blade roller guide member 230, it cannot move any further. That is, the movement of the first engagement blade 216 in the up-and-down direction is limited by the engagement blade roller guide member 230, and the position of the first engagement blade 216 in the up-and-down direction is determined. The portion 230a of the engaging blade roller guide member 230 with which the car door side engaging blade roller 228 contacts when the car door 102 is in a fully closed state is bent away from the car door 102, that is, upward. . Accordingly, when the car door 102 moves slightly from the fully closed state in the opening direction, the car door side engaging blade roller 228 is pushed down by the engaging blade roller guide member 230, and the first engaging blade 216 is pushed down. . As described above, in the case shown in FIG. 2A, when the first engagement blade 216 is pushed down, the car door of the first engagement blade 216 and the second engagement blade 218 is used. The interval in the opening / closing direction of 102 becomes narrow. This effect is related to the landing door interlock described later.

  FIG. 2B is a schematic diagram when the car door side engaging portion 110 is viewed from above. The opposing surfaces 216a and 218a of the first engagement blade 216 and the second engagement blade 218 include, for example, a portion perpendicular to the car door 102 and parallel to the ascending / descending direction (direction perpendicular to the drawing).

  FIG. 3 is a view of the landing door corresponding to the car door shown in FIG. 1 as seen from the hoistway side. Accordingly, the landing doors 302 and 304 shown in FIG. 3 correspond to the car doors 102 and 104 shown in FIG. 1, respectively. The landing doors 302 and 304 open and close in conjunction with the car doors 102 and 104 shown in FIG. 1, respectively. However, in a normal elevator system, an error occurs when the car is not stopped on the landing floor. There is no power unit for moving the landing doors 302 and 304 on the landing side because it is dangerous to open by operation. Further, the landing doors 302 and 304 are provided with an interlock portion 306 that prevents the landing doors 302 and 304 from opening when the car is not stopped on the landing floor. The interlock part 306 according to the present embodiment includes a landing door side engagement part. When the car arrives at the landing floor and stops at a predetermined position, the landing door side engaging portion provided in the landing door 302 and the car door side engaging portion 110 are engaged, and the landing door is the car door. To open and close. FIG. 3 also shows a landing door header 308 to which members for opening and closing the landing door 304 in conjunction with the landing door 302 are attached.

  Next, the interlock part 306 provided in the landing door according to the embodiment will be described with reference to FIG. On the hoistway side of the landing door 302, a first interlock member 402 having a tip portion 404 formed in a claw shape is attached so that the tip portion 404 can swing. On the hoistway side of the landing door 304, a second interlock member 406 having a recess is fixed. FIG. 4 shows a state in which the first interlock member 402 and the second interlock member 406 are interlocked. The landing doors 302 and 304 are interlocked via a first interlock member 402 and a second interlock member 406. In the interlocked state, the first interlock member 402 and the second interlock member 406 open the landing doors 302 and 304 even if an opening force is applied to at least one of the landing doors 302 and 304. Has no shape and strength. The landing state of the landing door shown in the figure is maintained until the car arrives at the landing floor where the landing door is installed, stops at a predetermined position, and the car door starts to open, ensuring safety. Is done.

  Moreover, the interlock part 306 according to the present embodiment includes a member 410 that is swingably attached to the hoistway side of the landing door 302 via a fixing member 408. One end of the member 410 is connected to the first interlock member 402 via the link member 412. The fixing member 408 pivotally supports a first roller 414 provided further on the hoistway side than the member 410. Further, as shown in the figure, on the hoistway side of the member 410, in the interlocked state, the first member 416 is rotatably attached by a fixing member 416 provided on the landing door 304 side than the first roller 414. Two rollers 418 are provided. The interlock operation will be described later with reference to FIG.

  FIG. 5 shows a state in which the car door side engaging portion 110 is engaged with the landing door 302. That is, when the car arrives at the landing floor where the landing doors 302 and 304 are provided and stops at a predetermined position, the interlock door 306 member provided on the landing door 302 and the car door side engagement. The state which the part 110 engaged is shown. Fig.5 (a) is the figure which looked at the engagement state from the hoistway side. In order to clarify the engagement state, the car door members are not shown except for the car door side engaging portion 110. When the car arrives at the landing floor provided with the landing doors 302 and 304 and stops at a predetermined position, the first engaging blade 216 and the second engaging blade 216 of the car door side engaging portion 110 are provided. Between the blades 218, the first roller 414 and the second roller 418 of the interlock portion 306 exist. At this time, the first interlock member 402 and the second interlock member 406 of the interlock portion 306 are in an interlocked state.

  FIG. 5B is a view of the portion indicated by I-I ′ in FIG. FIG. 5B shows a car door 102 corresponding to the landing door 302.

  The interlock operation will be described with reference to FIG. FIG. 6A is an enlarged view of the interlock portion 306 in FIG. 5A, and the first interlock member 402 and the second interlock member 406 are in an interlocked state. FIG. 6B shows a state where the interlock between the first interlock member 402 and the second interlock member 406 is released. As described above with reference to FIG. 2, when the car door 102 moves slightly from the fully closed state in the opening direction, the first engagement blade 216 is pushed down, and the first engagement blade 216 and the second engagement blade 216 The interval in the opening / closing direction of the car door 102 between the engagement blades 218 is narrowed. At this time, the second roller 418 is pushed by the second engagement blade 218 toward the first engagement blade 216, and accordingly, the member 410 swings in the direction in which the left end rises. A link member 412 is attached to the left end of the member 410, and the tip of the first interlock member 402 moves upward via the link member 412, and the first interlock member 402 and the second interlock member are moved upward. The interlock with the lock member 406 is released.

  FIG. 7 shows an embodiment of the present invention using some members of an engagement mechanism used in an elevator apparatus. The figure shows a state in which the car door 102 and a landing door 302 (not shown) that engages with the door are fully opened, with the landing door 302 being closed, viewed from the landing side outside the hoistway. It is a thing. The members attached to the landing door 302 are not shown except for the interlock portion 306. The figure shows a coil spring 702 that expands and contracts in the door opening and closing direction. One end of the coil spring 702 is attached to, for example, the door header 220 of the passenger compartment. When the car door 102 is fully open, the other end of the coil spring 702 pushes the first engagement blade 216 in the door closing direction with a force greater than the driving force for opening the door. When the first engagement blade 216 is pushed in the door closing direction, the first engagement blade 216 acts to push the first roller 414 and the second roller 418 attached to the landing door 302, and The second engagement blade 218 receives a force in the door opening direction, that is, in the direction approaching the first engagement blade 216 via the link members 202 and 204. Therefore, the coil spring 702 acts so as to reduce the distance between the first engagement blade 216 and the second engagement blade 218, and the landing door 302 is between the two car door side engagement elements 216 and 218. The rollers 414 and 418 attached to the vehicle are tightened by the car door side engaging members 216 and 218 attached to the car door. This tightening action increases the frictional force between the car door side engaging elements 216 and 218 and the rollers 414 and 418, and when the car room is shaken in the up-and-down direction, the braking effect against the shake can be enhanced. it can. The link members 202 and 204 need to be obliquely attached to the car door side engaging elements 216 and 218 as shown in the drawing. This is because, if the link member and the car door side engagement element are vertical, the above effect cannot be obtained even if the car door side engagement element 216 is pushed in the door closing direction. In this embodiment, the members of the car door side engaging portion 110 and the rollers 414 and 418 attached to the landing door 302 are members of an engagement mechanism that opens and closes the landing door 302 in conjunction with the car door 102. In addition, since it functions as a member of the vibration control mechanism of the passenger compartment, fewer members are added for the vibration control function.

  In addition, when the attachment position of the car door side engaging portion 110 to the car door 102 is inappropriate, the roller 414 or the like should not be located at the center of the gap between the car door side engaging elements 216 and 218. There is. However, even in such a case, either one of the car door side engaging elements 216 and 218 presses the roller 414 and the like, and a certain braking effect can be obtained. In addition, attaching the car door side engaging portion 110 to the car door 102 so that the roller 414 or the like is positioned at the center of the gap between the car door side engaging elements 216 and 218 is equivalent to the car door side engaging portion. 110 can be easily performed by adjusting the position of the plate 206 that is attached to the car door 102 or by using an appropriate jig or the like.

  The landing door 302 can also be provided with one or more braking members 704. While the first roller 414 and the second roller 418 play a part of the function of the interlock portion 306, the braking member 704 has nothing to do with the interlock function. Therefore, the brake member 704 does not need to satisfy the requirements necessary for the interlock function, and can use a shape, a material, or the like suitable only for the function of braking the vibration of the passenger compartment. When a plurality of braking members 704 are provided, the dimensions in the door opening / closing direction are the same, and the plurality of braking members 704 are provided so as to be aligned on a straight line parallel to the ascending / descending direction.

  There are various forms for attaching the coil spring 702. FIG. 8 is a schematic view of FIG. 7 as viewed from the top in order to show an example of an attachment form of the coil spring 702. Here, the door is in a state immediately before being fully opened. The attachment form shown in FIG. 8 is common in that the car door side engagement element 216 is pressed by the coil spring 702. 8A, the coil spring 702 is fixed to the spring fixing member 802, and the spring fixing member 802 is fixed to the door header 220 of the passenger compartment. In the form shown in FIG. 8B, the coil spring 702 is fixed to the car door side engaging element 216, and the stopper 804 that receives the pressure of the coil spring 702 is fixed to the door header 220 of the car room. The form shown in FIG. 8C is different from the form shown in FIG. 8A in that the spring fixing member 802 is fixed to the door header 308 of the landing. The form shown in FIG. 8D is different from the form shown in FIG. 8B in that the stopper 804 is fixed to the door header 308 of the landing.

As is well known, the pressing force F of the spring is proportional to the length (compression length) L of the spring when the spring is compressed from a free state. The relationship between the compression length L and the pressing force F of the spring is shown in FIG. In the present embodiment, the compression length L is the distance that the car door 102 has moved further in the opening direction from the state in which the coil spring 702 has touched the car door side engaging element 216 or the stopper 804. The fully open position of the car door 102 can be determined corresponding to the above. Further, by a position and a position corresponding to a first position in which the car door 102 is fully opened to the compression length L 1, the corresponding second position in which the car door 102 is fully opened to the compression length L 2 The pressing force of the spring in the fully open position can be set to different values such as F 1 and F 2 , respectively. By defining a plurality of positions at which the car door 102 is fully opened in this way, for example, the fully open position of the car door 102 is determined according to the landing floor where the vibration of the car room is large and the floor where the vibration is small. can do. The regulation and determination of the fully open position of the car door 102 can be performed by a control device, for example.

  In the above description, the case where the coil spring 702 is used as the pressing member has been described. However, the pressing member is not limited to the coil spring, and other appropriate springs, elastic bodies such as rubber, and a large rigidity are also provided. The member may be a metal, for example.

  FIG. 10 shows another embodiment of the present invention using some members of an engagement mechanism used in an elevator apparatus. The figure shows a state in which the car door 102 and a landing door 302 (not shown) that engages with the door are fully opened, with the landing door 302 being closed, viewed from the landing side outside the hoistway. It is a thing. In this figure, members attached to the landing door 302 are not shown except for the interlock portion 306. The drawing shows the engaging blade roller guide member 230 that is fixed to the door header 220 of the passenger compartment substantially parallel to the opening / closing direction of the passenger door 102, as described with reference to FIG. As described above, the engagement blade roller guide member 230 restricts the movement of the first engagement blade 216 in the up-and-down direction, and determines the position of the first engagement blade 216 in the up-and-down direction. When the car door 102 is fully open, the car door side engaging blade roller 228 attached to the first engaging blade 216 is in contact with the end portion 230b of the engaging blade roller guide member 230 in the door opening direction. Yes. The car door side engaging portion 110 is in the form shown in FIG. 10, that is, the connecting portions 212a and 212b of the link members 202 and 204 with the first engaging blade 216 are connected to the plate members 206 and 204, respectively. In the form of the fixing member 208 and the fixing member 210 attached to the same or lower than the fixing member 210, the end 230b of the engagement blade roller guide member in the door opening direction is bent downward. Therefore, when the car door 102 is fully opened, the car door side engaging blade roller 228 is pushed down by the engaging blade roller guide member 230 and the first engaging blade 216 is pushed down. As described above, in the case shown in FIG. 10, when the first engagement blade 216 is pushed down, the car door 102 is opened and closed by the first engagement blade 216 and the second engagement blade 218. The interval between directions becomes narrower. At this time, the first engagement blade 216 presses the engagement element with a force equal to or greater than the driving force for opening the door. As a result, the rollers 414 and 418 attached to the landing door 302 between the two car door side engaging elements 216 and 218 are tightened by the car door side engaging elements 216 and 218 attached to the car door. It is done. This tightening action increases the frictional force between the car door side engaging elements 216 and 218 and the rollers 414 and 418, and when the car room is shaken in the up-and-down direction, the braking effect against the shake can be enhanced. it can. Also in this embodiment, the members of the car door side engaging portion 110 and the rollers 414 and 418 attached to the landing door 302 are members of an engagement mechanism that opens and closes the landing door 302 in conjunction with the car door 102. In addition, since it functions as a member of the vibration control mechanism of the passenger compartment, fewer members are added for the vibration control function. The action of the end portion 230b in the door opening direction of the engaging blade roller guide member shown in FIG. 10 will be further described later with reference to FIG.

  Similarly to the embodiment shown in FIG. 7, when the mounting position of the car door side engaging portion 110 to the car door 102 is inappropriate, the roller 414 or the like is used for the car door side engaging element 216. And 218 may not be located at the center of the gap. However, even in such a case, either one of the car door side engaging elements 216 and 218 presses the roller 414 and the like, and a certain braking effect can be obtained. In addition, attaching the car door side engaging portion 110 to the car door 102 so that the roller 414 or the like is positioned at the center of the gap between the car door side engaging elements 216 and 218 is equivalent to the car door side engaging portion. 110 can be easily performed by adjusting the position of the plate 206 that is attached to the car door 102 or by using an appropriate jig or the like. Also, the landing door 302 can be provided with one or a plurality of braking members 704, as in the embodiment shown in FIG.

  Note that the connecting portions 212a and 212b of the link members 202 and 204 with the first engagement blade 216 are located above the fixing member 208 and the fixing member 210 that attach the link members 202 and 204 to the plate 206, respectively. In the embodiment, the end portion 230b of the engagement blade roller guide member in the door opening direction is bent upward. If the first engagement blade 216 is pushed down, the distance between the first engagement blade 216 and the second engagement blade 218 in the opening / closing direction of the car door 102 is increased.
