Description

elevator

The present invention relates to an elevator, and more particularly to an elevator suitable for a low-rise building such as a house.

In the most common conventional residential elevators, a saddle whose center of gravity moves due to the movement of the load of a person or the like is hung with a wire at one or two places, and a vertical rotational force is generated on the saddle. Furthermore, by supporting the kite on the two guide rails, the vertical rotation of the kite was suppressed, and the roll and lateral rotation of the kite due to earthquakes and the like were suppressed. In addition, the landing door and the saddle door are made of steel sliding doors having a pull-in allowance, and are automatically opened and closed in synchronization with the operation control mechanism by a driving device provided on the saddle.

Also, the second conventional residential elevator has a box (hoistway) provided with saddle guide rails at the four inner corners, and a drive unit for winding up the belt. Then, the bag is suspended in the box by a belt connected to the center of the upper surface of the bag, and a vertical rotational force is generated in the bag while the vertical rotation of the bag is suppressed by the box.

In addition, the second conventional residential elevator uses a swing door and a landing door which is an entrance / exit of the box device as a manual swing door, and the landing door and the saddle door are connected to each other by an engaging means provided on each door at the landing. Were linked and opened and closed. Then, an electric lock that automatically locks when the door is closed is provided on the landing door, and at the landing, the fence door is opened and closed freely to follow the landing door. Furthermore, during raising and lowering, the roller provided at the top and bottom of the door tip is fitted into the guide rail of the box device, so that the swinging of the coffin door is restricted and locked. And when getting on and off, the electric lock of the landing door was remotely operated and unlocked by any one of the switches provided in the landing and in the cabin.

JP 2003-192261 A Japanese Patent Laying-Open No. 2005-314016 JP 2006-151555 A JP 2002-114467 A Japanese Patent Laid-Open No. 52-152047 Japanese Patent Laid-Open No. 1-244091

As described above, the first conventional residential elevator has the canopy supported by the two guide rails in a cantilever manner so that the vertical suspension is generated in the canopy. Therefore, as the stress, a force that distorts the heel, a force that causes the entire two guide rails to fall, and a force that twists sideways have occurred. And the force which arises in the two guide rails was borne to the installation building as a horizontal load load.

Also, the force that distorts the kite and the force generated on the guide rail are directly proportional to the kite's own weight and the load, and increase or decrease depending on the position change of the kite's center of gravity. However, in the first conventional residential elevator, a steel sliding door, which is much heavier than a common living room door such as a wooden door, is used for the awning door, and an automatic opening / closing driving device is provided on the awning. Therefore, its own weight is large. In particular, when doorways are provided in two directions, a door load is added at a position further away from the guide rail, and the vertical rotational force of the heel increases, so that the force that distorts the heel and the force generated in the guide rail It was increasing.

That is, in the first conventional residential elevator, rigidity is required for the kite to resist the force that distorts the kite. On the other hand, the general technology for increasing the rigidity involves heavy use of heavy members such as steel, so there is a contradiction that the rigidity of the heel is increased and the weight of the heel is increased, resulting in an increase in the force that distorts the heel. However, there is a difficulty that it is difficult to reduce the weight.

In addition, as the two guide rails, in order to resist the rotational force of the heavy weight of the kite, a member having a stronger and larger cross section than that of a general wooden house pillar is used. Moreover, it is necessary to install two guide rails separately from the pillar of a building with high precision. Furthermore, because the sliding door made of steel with a large allowance compared to the swing door is used, the required floor area of the hoistway with respect to the floor area of the fence is large, and the utilization efficiency of the floor area is low. there were.

Moreover, the 2nd conventional residential elevator comprises the hoistway wall conventionally comprised as a building as a main apparatus. Therefore, it is inefficient to apply the configuration to a general size such as the first conventional residential elevator. Further, the configuration is suitable for application to a small device, but is not suitable for application to a medium or large device.

The problem to be solved by the present invention is to provide an elevator capable of solving the problem caused by the vertical rotational force generated in the wire-suspended kite with a simple configuration.

The elevator according to the present invention raises and lowers the wire-suspended fence in the hoistway. This elevator has a suspension device and a wire connecting portion. The suspension device is provided at the top of the hoistway and winds three or more wires in synchronization. The wire connecting portion is provided on the heel and is provided in the same number as the plurality of wires. The plurality of wires and the plurality of wire connecting portions are connected one to one. The kite suspended by the plurality of wires is freely deformed such that the plurality of wire connecting portions are displaced in the vertical direction independently of each other. The range of movement of the barycenter of gravity is limited to a range included in a polygon whose apexes are vertical load support points of a plurality of wires on the horizontal projection plane.

According to the present invention having the above-described configuration, it is possible to prevent the generation of vertical rotational force on the wire-suspended cage. Therefore, it is possible to solve the problem caused by the vertical rotational force generated in the wire-suspended hook with a simple configuration.

Therefore, the load applied to the installation building is only the seismic load due to the weight of the device and the load, as in general furniture, and in the hoistway, the strong guide rail in the first conventional residential elevator, Equipment that requires installation space, such as boxes in the second conventional residential elevator, is no longer necessary, suppresses rolling of the kite caused by an earthquake or a walking movement of the passenger, and makes contact between the kite and the hoistway Since it is sufficient to use a simple device only for prevention, it is effective in reducing the hoistway area and cost.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. In addition, about the ratio of the whole dimension of a figure and a partial dimension, an aspect ratio, etc., exaggeration is included for convenience of explanation.

In the figure, α is a dirt floor continuous with the outdoors. β is the first floor set about 40 cm higher than the dirt floor. γ is a mezzanine floor. δ is the second floor. ε is a flat rectangular hoistway that communicates across the floor. ζ is a staircase that climbs from floor β to floor γ. Η is a pillar of the building suspended from the four corners of the hoistway ε, and a hoistway inner surface entrance angle θ composed of two vertical belt-like surfaces forming a plane L shape is formed.

1 is a flat square ridge. Reference numeral 2 denotes a suspension device (drive device, mount, etc .: not shown) provided with two sets 3 of winding cylinders. The suspension device 2 is supported by a building (not shown) at the top of the hoistway. Reference numeral 4 denotes a pole pillar suspended from the four corners of the fence 1. The column 4 has a joining plate 4a composed of two vertical plates at the upper part and the lower part of the side surface facing two orthogonal sides. Reference numeral 5 denotes a girder having a joining plate 5a made of a single vertical plate at both ends. The joining plate 5a is slidably fitted in the interval between the two vertical plates of the joining plate 4a.

Reference numerals

6 and 6a denote pins for joining the steel pillars and the steel beams, which respectively penetrate the

joint plates

4a and 5a. A total of four pole pillars 4 and a total of eight bridge beams 5 constitute a quadrangular columnar shaft set (see FIG. 2).

It should be noted that the present invention is not limited to the rectangular plane ridge shown in this embodiment, and can be applied to any polygonal plane ridge. Needless to say, the form of the joining means between the column and the beam is not limited to this embodiment.

The frame with the side pillars 4 on both sides of the axis set and both sides of the side poles and the upper and lower sides of the bridge 5 has a rectangular shape with the pin 6 at the four corners as vertices when the bridge 5 is horizontal. It is arranged. Further, the joint angle in the vertical plane between the vertical column 4 and the vertical beam 5 is configured to freely vary with the pin 6 as the central axis. Thereby, all the rectangular frameworks on the side surfaces of the shaft assembly are freely deformed into parallelograms.

On the other hand, in the above-described framework, when the vertical difference between the vertical pillars 4 on both sides becomes the distance h1, the pin 6a contacts the inner surface of the loose hole 5b provided in the joining plate 5a. Thereby, the fluctuation | variation of the joint angle of the vertical column 4 and the vertical beam 5 is controlled. Therefore, the two

pins

6 and 6a apply bending stress to the vertical column 4 and the vertical beam 5 for a load that attempts to deform the frame so that the vertical difference between adjacent vertical columns 4 is equal to or greater than the distance h1. In order to generate, the frame resists its load so that it does not deform further (see FIGS. 3A and 3B).

That is, the shaft assembly of the present embodiment can freely move up and down independently of each other while maintaining all the vertical pillars 4 vertical within a range in which the vertical difference between adjacent vertical pillars 4 is equal to or less than the distance h1. It is possible to deform. On the other hand, the shaft assembly resists deformation load so as not to deform beyond the above range. Further, in the present embodiment, for the purpose of securing a three-dimensional shape necessary for protecting a passenger, the shaft assembly that can be deformed within a predetermined range is used as the main structure of the kite 1.

Next, 7 is a wire connecting portion, which is provided on the upper surface of the joining plate 5a at both ends of the two beams 5 facing in parallel on the upper surface of the shaft assembly. When the vertical difference between the vertical poles 4 on both sides of the frame is a distance h1, the vertical difference between the wire connecting portions 7 located on the left and right of the frame is a distance h2. That is, these wire connecting portions 7 are provided at positions that can be moved up and down independently of each other within a range in which the vertical difference between adjacent wire connecting portions 7 is equal to or less than the distance h2 by deformation of the shaft set.

Moreover, the group 3 of winding cylinders hangs and raises the hook 1 in this embodiment directly by the winding cylinder in which the load support point of the wire moves with winding.

That is, the winding drum set 3 is a set of two winding drums having the same winding diameter and winding interval and different winding directions into a right winding and a left winding. The two winding drums simultaneously wind up two wires, one at a time, at a predetermined interval. Thereby, the two load supporting points of the two wires are moved symmetrically. At this time, the center point and the direction of the line segment connecting the vertical load support points of the two wires are prevented from moving on the horizontal projection plane.

That is, by suspending one girder in a swing shape with the two wires of the winding cylinder set 3, the horizontal distance between the vertical load support points of the two wires and the wire connecting portions at both ends of the girder is increased. It ’s different. Thereby, the horizontal force generated when the wire is tilted can be absorbed by the pair of the girder and the winding drum. For this reason, the position and posture of the beam are kept constant, as in the case where the beam is suspended and rolled up with two wires suspended from the two sheaves so that the vertical load support point does not move. With this, the beam can be raised and lowered.

And in the hoistway ε, two wires 8 wound up by each of the two sets 3 of the winding drums of the suspension device 2, and two wire connecting portions 7 in each of the two girder beams 5, Are connected to each other.篭 1 will land on the second floor δ, the top floor. When all the beams 5 are horizontal, a total of four wires 8 are vertical.

In the configuration as described above, the polygon having the vertex at the vertical load support point on the horizontal projection plane of the plurality of wires with the heel suspended is substantially congruent with the polygon on the heel plane, and the movable range of the centroid of the heel is defined. Inevitable. Therefore, no vertical rotational force is generated on the heel.

In addition, in a plurality of wires in which a hook is suspended, when an expansion / contraction difference or a winding difference due to a load difference and a characteristic difference in each wire occurs, the vertical difference between two adjacent wire connecting portions 7 is less than a distance h2. In such a range, the shaft set is deformed according to the expansion / contraction difference or winding difference of each wire. Also, in that deformation, all the saddle pillars are kept vertical and parallel to each other.

Strictly speaking, if there is a difference between the horizontal distance between the vertical load support points of the two wires of the winding drum set and the horizontal distance between the wire connecting portions at both ends of the girder, the wire is slightly Tilt. In a state where the wire is inclined, if the position of the center of gravity of the girder changes, the inclination of the two wires changes in the same direction, so that the inclination of the girder and the position in the axial direction shift. However, these deviations and the resulting horizontal force are negligible within a negligible range. Further, even when the girder is tilted within a predetermined range, the vertical posture of the eaves column is maintained. Therefore, such a phenomenon is not a problem in practice. Further, the position of the wire connecting portion in the girder is not limited to both ends, but considering that the inclination of the girder due to the difference in the upper and lower wires is minimized when both ends are hung, this configuration seems to be preferable. .

In addition, there is a suspension device in which wire connection portions are provided at all the tops of the pole posts and each wire is suspended from the sheave from the sheave to the wire connection portion so that the vertical load support point of the wire on the horizontal projection plane does not move. Has been applied. Thereby, it is possible to raise and lower the wrinkles of an arbitrary polygonal plane in a state where the position is kept strictly constant. In addition, the generally used plane is a rectangle. In addition, a suspension device using a winding drum group uses less wire and has a simpler structure than a suspension device using a sheave.

That is, since the kite 1 is suspended by the four wires 8 that the hoisting device 2 winds up, its position and posture are kept constant except when an earthquake or a horizontal force is applied to the kite 1. It will be kept up and down.

By the way, conventionally, when a large structure such as a bridge, which is an integral rigid body, is hung at a fixed position and posture by a plurality of wires connected to a plurality of points surrounding the center of gravity, the load difference and characteristic difference in each wire described above are used. In order to eliminate the problem of expansion / contraction difference or winding difference due to the above, a control device for adjusting the winding amount of each wire is required. For this reason, in an elevator for a general building that requires ease of maintenance and low cost, the wires are connected to and suspended from a plurality of points surrounding the center of gravity of the fence so as not to generate vertical rotational force on the fence. The technology to do was not put into practical use.

For example, Patent Document 4 describes that an elevating body (篭) is suspended by four belts. Patent Document 5 describes that an elevator cable (wire) is connected to each of the four corners of the elevator platform (篭). However, in these documents, there is a description relating to solving the problem caused by the vertical rotational force generated in the wire-suspended cage by hanging the kite at a plurality of points that are three or more points surrounding the center of gravity of the cage. There is no suggestion.

Next, 9 is a roller (including a support shaft and attachment means: not shown). The rollers 9 are respectively provided at the upper and lower portions of the column 4 which are substantially four corners of each frame on the side surface of the shaft assembly. θ is a corner that forms a plane L shape of the inner surface of the hoistway provided in the column η of the building. The entrance corner θ has two vertical surfaces that face the shaft side surface in parallel with a predetermined distance therebetween. A cushion belt κ made of hard rubber or the like is laid on each vertical surface of each entry corner θ. Each roller 9 is configured to come into contact with the cushion belt κ without applying a horizontal force when the rod 1 is suspended at a predetermined position in the hoistway ε (see FIGS. 4 and 5).

Therefore, the horizontal force generated in the fence 1 by an earthquake or the like is quickly transmitted to the pillar η of the building via the roller 9 and the cushion belt κ. As a result, the roll of the heel 1 is restricted to a slight distance range in which the cushion belt κ expands and contracts by the reaction force of the column η. At that time, the kite 1 does not receive a force for rotating or distorting the same as the four-wheeled vehicle traveling on the horizontal plane.

10 is a door. The coffin door 10 is attached to the coffin pillar 4 via the hinge 11 and swings open and close to the outside of the coffin 1. Reference numeral 12 denotes a door opening and closing device. The door opening / closing device 12 is arranged at the approximate center of the door end of the sash door 10. Reference numeral 14 denotes a spear guide. The scissors guide 14 is fixed to the entrance corner θ. The heel door 10 is locked by fitting the heel guide 14 with the heel 15 of the door opening and closing device 12. Furthermore, the collar 15 can be moved up and down freely while maintaining the fitted state. Reference numeral 16 denotes a landing door. The landing door 16 is attached to the door frame λ via a hinge 17 and swings open and close outside the hoistway. Reference numeral 18 denotes a door opening and closing device. The door opening / closing device 18 is arranged in the approximate center of the door end of the landing door 16. Further, the height of the eaves door 10 is configured to be shorter than the landing door 16 so that the eaves door 10 can be opened and closed even when the eaves 1 are shifted vertically within the range of the distance h3. (See FIG. 5). The difference between the door opening and

closing devices

12 and 18 is only the shape and the rotation direction of the tip of the flange 15, and the other configurations are the same. Moreover, it can be used as a right-opening door or a left-opening door by exchanging the eaves 15. In the present embodiment, such differences will be omitted.

Incidentally, in the bag of this embodiment, the slide door frame can be applied to the landing door and the lid door by configuring the slide door frame so as not to resist the deformation of the shaft assembly (not shown). However, the swing door only needs to be hinged to the vertical pole that keeps the vertical parallel to the deformation of the shaft set, so the configuration is simpler than the slide door, and it is also suitable for weight reduction and cost reduction.

19 is a receipt. The guard 19 is provided on the landing door frame λ. The guard 19 is integrally formed with a door stop that stops the landing door 16 at a predetermined closing position in the landing door frame λ, and is directly joined to the saddle guide 14. Therefore, the door opening / closing device 12 of the fence door 10 is guided up and down without being affected by the roll of the fence 1 so as to keep the distance between the landing door 16 and the door opening / closing device 18 constant.

22 is a wall board.

Reference numerals

23 and 23a denote a pair of hook hardware (see FIG. 8) having a known structure that is attached and detached by moving one side up and down by a distance h4. The wall plate 22 is attached to the frame on the side surface of the shaft assembly by

hook hardwares

23, 23a provided at four places on the left, right, top and bottom. Therefore, in the framework, the wall plate 22 slides up and down while displacement of the wall surface in the direction perpendicular to the wall is restricted.

24 is a stopper. The stopper 24 restricts the displacement in the vertical direction in the frame of the wall plate 22 or the door 10 to the range of h1. The stoppers 24 are attached to predetermined positions on the lower surface and the upper surface of the joining

plates

4a and 5a, respectively. These stoppers 24 have a distance h <b> 1 with respect to the upper surface of the wall plate 22 or the upper and lower surfaces of the roof door 10 when the roof beam 5 is horizontal (see FIGS. 6A and 6B). Therefore, the wall plate 22 is prevented from falling off the frame. Furthermore, when the vertical difference between the vertical pillars on both sides of the frame is going to exceed the distance h1, the wall plate 22 or the vertical door 10 interferes with the stopper 24 and acts to resist deformation of the frame (FIGS. 7A and 7B). FIG. 7C).

In addition, the means for attaching the wall plate is not limited to this. For example, although not shown in the figure, the distance h1 is set without dropping the wall plate from the frame structure, such as a configuration in which the wall plate is sandwiched from the inner surface and the outer surface by a push edge, which is a general means for attaching the glass plate to the window frame of the building. A means that can be slid up and down can be applied.

25 is a ceiling board. The ceiling plate 25 is made of a resin plate or the like that is thin and light and has almost no surface rigidity. The ceiling plate 25 is flexibly deformed following the deformation of the upper surface of the shaft set. Reference numeral 26 denotes a floor plate 26. The floor plate 26 is made by connecting square bars 26a made of wood or the like in a bowl shape at a predetermined interval with a steel wire 26b. The floor plate 26 moves up and down at a distance of h1 or more independently of each other by twisting two opposing sides freely. Both ends of each square bar 26a are supported at an angle with respect to the receiving bar 27. The receiving bar 27 is fixed to the two beams 5 facing each other on the lower surface of the shaft assembly. With such a configuration, the floor plate 26 is freely deformed into a curved surface following the deformation of the shaft assembly while transmitting the load loaded on the floor surface to the shaft assembly as in the case of no deformation (FIG. 9). reference).

As described above, the bag in the present embodiment is configured to freely deform within a predetermined range. Furthermore, if any of the multiple wires that suspend the heel breaks, causing a load that causes the shaft assembly to be deformed beyond a predetermined range, any of the surface members or their attachment means, etc. Acts to resist deformation of the shaft set. Thereby, it is possible to ensure the safety of the passenger while realizing simplification of the device and weight reduction of the bag. Further, for example, by using four wires, it is possible to prevent a situation where all the wires are cut at the same time and the heel is dropped.

In the door opening and

closing devices

12, 18, 28 is a connecting rod having a predetermined long axis length. The connecting rod 28 has a ridge parallel to the long axis that is raised perpendicularly to the door surface on the left and right sides of the front. One protrusion has an I-shaped cross section, and a protrusion 28a having a trapezoidal side surface is provided on the front surface. The other protrusion has its tip bent inward and its cross section is formed in an L shape. Between these protrusions, both ends are opened and a groove having an L-shaped cross section is formed (see FIGS. 10A and 10B). These protrusions are connected to each other by sliding the protrusions of the second connecting rod 28 parallel to the long axis from the small opening side and fitting them into the grooves (see FIG. 13A). When one of the two connecting rods 28 in the connected state is displaced in a short axis direction parallel to or perpendicular to the door surface, the two connecting rods 28 are constrained to be displaced together. (See FIG. 12C).

29 is a rotating plate for holding the connecting rod 28. Reference numeral 30 denotes a rotation axis orthogonal to the door surface. 31 is a handle. The rotating plate 29, the rotating shaft 30, the handle 31, and the flange 15 (or the flange 20) are connected so as to rotate integrally. Reference numeral 32 denotes a box having a bearing (not shown) of the rotating shaft 30. The box 32 has locking

pins

33 and 33a for restricting the rotation range of the rotation plate 29 to 90 degrees. Reference numeral 34 denotes a spring. Both ends of the spring 34 are hooked by hook pieces 34 a provided on a slide rail 36 and a box 32, which will be described later, fixed to the rotating plate 29. And when the rotation board 29 exists in the intermediate point of a rotation range, the tension action line 34b of the spring 34 and the axial center 30a of the rotation axis | shaft 30 are comprised so that it may cross | intersect. Therefore, when the rotation plate 29 is shifted in the left-right direction from the intermediate point, the rotation plate 29 is biased and rotated toward the tension acting line 34b having a space from the axis 30a.

Therefore, when the user releases the handle and interrupts the locking operation (or unlocking operation), the rotating plate 29 rotates in the locking direction (or unlocking direction) with the tension of the spring 34. When the rotation of the rotating plate 29 is stopped by the locking

33 or 33a and the long axis of the connecting rod 28 becomes vertical, the

rod

15 or 20 is disposed at the locking position. Further, when the long axis of the connecting rod 28 becomes horizontal, the

flange

15 or 20 is disposed at the unlocked position (see FIGS. 14A and 14B). In addition, when the above-described rotation operation is completed, the rotational force due to the handle operation is not transmitted to the subsequent mechanism (interlocking side), and hence the rotation difference described later indicates that the interlocking side rotation is incomplete. This problem is solved by the spring 34.

When the locked landing door 16 and the coffin door 10 face each other at the landing, the connecting rod 28 of the coffin door 10 is configured to slide into the connecting rod 28 of the landing door 16 from above or below. Therefore, when the locking operation or the unlocking operation is performed by the handle of the landing door 16 or the lid door 10 in a state where the rod 1 is landed at a predetermined position, the connecting rods 28 of both the door opening and

closing devices

12 and 18 are integrated. And the landing door 16 and the heel door 10 are integrally locked or unlocked. In addition, when the handle of the landing door 16 or the coffin door 10 is operated in the unlocked state, the connecting rods 28 of the door opening and

closing devices

12 and 18 are pushed and pulled together, and the horizontal direction when the swing is opened and closed. The misalignment is absorbed by both connecting rods 28 sliding in the long axis direction. Thereby, the landing door 16 and the coffin door 10 are integrally opened and closed. In addition, said position shift originates in the difference in the position of the hinge of the landing door 16 and the coffin door 10. FIG.

35 and 36 are a pair of slide rails. The slide rails 35 and 36 are provided on the connecting rod 28 and the rotating plate 29, respectively. The connecting rod 28 is held on the rotating plate 29 by

slide rails

35 and 36. Reference numeral 37 denotes a spring. Both ends of the spring 37 and both ends of the slide rail 36 are hooked to each other. The center of the spring 37 and the center of the slide rail 35 are hooked to each other (the hook means is not shown). With such a spring 37, the connecting rod 28 is arranged at a predetermined position of the rotating plate 29. Further, due to an external force in a direction parallel to the door surface, the connecting rod 28 is freely displaced laterally within a predetermined range independently of the rotating plate 29. For this reason, the connecting rod 28 rotates integrally with the rotating plate 29 and is laterally shifted in the short axis direction (direction parallel to the door surface) independently of the rotating plate 29.

The above configuration corresponds to the slide mechanism of the present invention. In the state where the long axis is positioned vertically, the connecting rod 28 is in a connected state. Further, in the two door opening and

closing devices

12 and 18 having the vertical difference h3, play is interposed in the two connecting rods 28 in the connected state in the minor axis direction parallel to the door surface. The connecting rod 28 can be formed so that the play distance is a suitable value of h3 or less. Thereby, the locking operation and the unlocking operation become smooth.

By the way, in general, it is difficult to eliminate the displacement of the landing position in the vertical direction in the lifting mechanism that hangs the fence. Temporarily, in the door opening and

closing devices

12 and 18 having a vertical difference, the sliding mechanism is not provided, the connecting rod 28 and the rotating plate 29 are fixed, and there is play between the two connecting rods 28. If it is not provided, the two connecting rods 28 do not rotate together. Then, the locking operation and the unlocking operation are not performed in conjunction with each other. In addition, when play is provided between the two connecting rods 28 but no slide mechanism is provided, the major axis of the up-and-down difference that enables interlocking locking and unlocking operations is arranged horizontally. The distance at which the two connected rods 28 can be connected, that is, the play distance. Then, due to the play, a rotation difference (a phenomenon in which the interlocking side is delayed from the operation side) occurs in the interlocking rotation of the two connecting rods 28. This rotational difference is proportional to the distance of play.

That is, in the case where the slide mechanism is not provided, the play is the distance h3, and the cross-sections of the two connecting rods in the connected state are configured as shown in FIG. 18A, as shown in FIGS. The difference in rotation differs greatly between when the operation side is higher and when it is lower. That is, in the locking operation and the unlocking operation, the responsiveness of the interlocking locking operation and the unlocking operation on the handle operation changes significantly.

FIG. 18B is a schematic diagram showing a state in which the long axes of the two connecting rods are vertically fitted without any difference between the upper and lower sides. mF and mL indicate connecting bars on the interlocking side and the operating side, respectively. FIGS. 19A to 19C and 19D to 19F are schematic views showing the position of the connecting rod mL when the connecting rod mF is rotated to the middle point (45 degrees) of the rotation range in the locking operation and the unlocking operation, respectively. FIG. In addition, R in these figures is an angle which shows a rotation difference. Further, FIGS. 19A and 19D show a case where the rotating shafts 30 on the interlocking side and the operation side are the same. FIGS. 19B and 19E show the time when the operation-side rotary shaft 30 is higher by the distance h3. FIGS. 19C and 19F show a case where the operation-side rotation shaft 30 is lower by a distance h3.

By applying the configuration as described above, the responsiveness of the locking operation and the unlocking operation can be made similar to that of a general door handle operation. Therefore, the user can operate the elevator with peace of mind. Further, if the responsiveness at the time of operation changes, it is considered that the user recognizes some abnormality.

Further, in the two door opening and

closing devices

12 and 18 that make a vertical difference of the distance h3, the slide mechanism of this embodiment is provided, and the two vertical connecting rods 28 are connected to each other to absorb the vertical difference. By doing so, the play in the direction parallel to the door surface in the connecting rod 28 can be set to a suitable distance of h3 or less, and it is possible to suppress the change in the rotation difference in the interlocking locking and unlocking operations. .

17A to 17F show the connecting rod 28 between the interlocking side and the operation side when the interlocking side is rotated to the middle point of the rotation range in the locking operation and the unlocking operation when the slide mechanism is provided. This is shown schematically. In FIG. 17A, 28F and 28L are the connection side 28 and the operation side connecting rod 28, respectively. 17A-C show the locking operation. 17D-F show the unlocking operation. Further, FIGS. 17A and 17D show the time when the pivot shaft 30 on the interlocking side and the operation side is the same. FIGS. 17B and 17E show the time when the operation-side rotation shaft 30 is higher by the distance h3. FIGS. 17C and 17F show a case where the operation-side rotation shaft 30 is lower by a distance h3. In these figures, S1, S2, and S3 indicate lateral displacement distances of the connecting rod 28. S3 is a lateral shift limit distance. R is the angle of the rotation difference.

38 is a lock piece in the lock mechanism of the present invention. The center of the lock piece 38 is pivotally supported in the through slit 29a of the rotating plate 29 so as to swing in a direction perpendicular to the door surface. When the long axis of the connecting rod 28 is vertical, one end of the lock piece 38 is biased so as to fit into the locking hole 32a of the box 32 (support shaft, mounting means, biasing). Means etc .: not shown). Thereby, the rotation of the rotating plate 29 is locked by the lock piece 38 fitted to the box 32, and the unlocking operation is prohibited. Therefore, an unauthorized unlocking operation in a state where the bag is not landed can be prevented (see FIGS. 12A, 12B, and 12C). On the other hand, by inserting a hairpin or the like into a guide hole (not shown) penetrating through the locking hole 32a provided on the handle side door surface, the lock piece 38 can be rocked and removed from the locking hole 32a. Therefore, the lock can be easily released at the time of inspection or emergency.

39 is a rocking plate (support shaft, mounting means, etc .: not shown) pivotally supported by the connecting rod 28. The swing plate 39 is pressed against the back surface of the connecting rod 28 by the end of the biased lock piece 38. Reference numeral 40 denotes a contact roller (support shaft, mounting means, etc .: not shown) that is pivotally supported by the swing plate 39. The abutting roller 40 abuts against and slides on the protrusion 28 a of the second connecting rod 28 fitted into the connecting rod 28. When the vertical difference between the two connecting rods 28 fitted is within an allowable range (distance h3), the swing plate 39 swings integrally with the contact roller 40 and presses and swings the lock piece 38. It is configured to be removed from the locking hole 32a (see FIGS. 12A, 12B, 12C, 13A, 13B, 15A, 15B, and 15C). Thereby, when the kite 1 is landed within a distance h3 in the vertical direction from the predetermined landing position, the prohibition state of the unlocking operation of the kite door 10 and the landing door 16 is released.

篭 The door 10 and the landing door 16 are opposed to each other with a vertical difference within a distance h3. When one handle of the coffin door 10 and the landing door 16 is operated, unlocking is interlocked and the door opens to the landing side. Then, the two connecting rods 28 that are fitted in a state in which the long axis is disposed horizontally are engaged in the front-rear direction while being displaced in the horizontal direction. Thereby, the coffin door 10 and the landing door 16 operate integrally in the direction perpendicular to the door surface and open integrally. Further, the swing plate 39 has a predetermined width so that the lock piece 38 can be pressed even when the connecting rod 28 and the rotation plate 29 are displaced by the slide mechanism (see FIG. 16A, see FIG. 16B). And as shown in FIG. 4, the coffin door 10a and the landing door 16a open. When the horizontal displacement distance S between the two connecting rods 28 exceeds the distance h3 as shown in FIG. 15A, one end of the urged lock piece 38 is fitted into the locking hole 32b of the box 32. The locking operation is prohibited. As a result, as shown in FIG. 4, the allowance for the two connecting rods 28 when the saddle door 10 b and the landing door 16 b are opened can be set to a short distance that can be engaged only in the front-rear direction. Therefore, the connecting rod 28 can be reduced in size.

That is, if the case where the locking operation of the door opening / closing device is not prohibited at the time of interlocking door opening, the two connecting rods that are fitted are displaced so that they cannot be interlockedly rotated. If the locking operation is mistakenly performed in a state where these hooking margins are small, only the connecting rod on the operating side may rotate and the two connecting rods may come off. If the long shaft is designed to be long in order to increase the allowance for the connecting rod when the door is opened, the connecting rod in the front-rear direction is used to absorb the angle difference between the coffin door and the landing door. It is necessary to increase the play. In particular, when a small cage is applied, the angle difference between the cage door and the landing door when the door is opened becomes larger, so that it is necessary to further increase the play of the connecting rod. For this reason, when interlocking unlocking of the coffin door and the landing door, the fluctuation range of the distance between the doors becomes large, and as a result, the certainty of the interlocking locking is lowered. In addition, in a coffin door and a landing door in which the connecting rods are fitted in a predetermined position and the long axis is fitted vertically, the connecting rods are provided with a difference in the upper and lower sides in advance. Even if the length of the long axis of the door is suppressed and the hanging allowance at the time of opening the door is increased, the setting position of the projecting portion which is the action part of the locking mechanism in the connecting rod is different between the side door side and the landing door side As a result, two types of connecting rods are required.

That is, according to the lock mechanism of the present embodiment, an illegal locking operation on the coffin door 10 or the landing door 16 that is opened in an interlocking manner can be prohibited only by providing the locking hole 32b in the box 32. Therefore, the connecting rod 28 can be reduced in size without impairing safety. Moreover, the usability of the door opening and

closing devices

12 and 18 can be improved. Furthermore, the number of parts can be reduced.

Further, in the present embodiment, the parts having different shapes in the set of the door opening and

closing devices

12 and 18 are limited to the

eaves

15 and 20. Further, in the set of door opening and

closing devices

12 and 18, members having different mounting directions and mounting positions are only the rotating plate 29 and the

flanges

15 and 20, and further the box 32 and the slide rail 36. Thereby, the direction which a door opens can be switched only by exchanging the eaves 15 and the eaves 20. Further, by connecting the handle, the rotating shaft, the rotating plate, and the rod and rotating them integrally, the rotating mechanism of the connecting rod can be simplified and the cost can be reduced. The rotating mechanism of the connecting rod in the door opening and closing device of the present invention is not limited to this. Although illustration is omitted, for example, for a person who is difficult to rotate the handle by 90 degrees, the rotation angle of the handle can be reduced by connecting the handle and the rotation shaft via a gear. In addition, an electric drive device can be provided as a rotation mechanism so that a locking operation and an unlocking operation can be performed by an operation means such as a push button.
