An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. FIG.

As shown in FIG. 1 , the elevator 1 includes a hoistway 2 extending vertically across a plurality of floors in the building, and a car 3 that moves up and down the hoistway 2 . The car 3 can ascend and descend in the hoistway 2 and stop at landings 4 provided on each floor of the building.

As shown in FIG. 2, the elevator 1 accommodates a door operator 5 for opening and closing a car door 31 and components 50 of the door operator 5. and a storage unit 6 provided. In the elevator 1 of this embodiment, the component mounting surface 32 is the vertical surface 32 belonging to the car 3 .

The vertical plane 32 is a plane substantially along the vertical direction (the vertical direction of the car 3). Further, the "vertical plane 32 belonging to the car 3" broadly includes the vertical planes of the respective parts constituting the car 3. As shown in FIG. In other words, the vertical surface 32 is not limited to the surface forming the inner wall of the car 3 (the surface exposed to the internal space of the car 3), but for example, a structure attached to the surface forming the inner wall of the car 3. Also includes vertical planes in parts. The same applies to a vertical plane 42 belonging to the hall 4, which will be described later. The door operator 5 includes a door opening/closing device 7 that generates an opening/closing force for opening and closing the car door 31 or the landing door 41, and a guide rail 51 that guides the car door 31 or the landing door 41 (see FIG. 2). The storage unit 6 is separate from the car 3 and has a rectangular parallelepiped shape in this embodiment. Further, since the storage part 6 may protrude into the car 3, it may be formed with a curved surface in consideration of aesthetics.

Here, the components 50 include, for example, a hanger 57 for hanging the car door 31, a door motor 52 related to generation and transmission of driving force, an inverter 59, a drive pulley 53, a driven pulley 54, a drive belt 55, and a car door. A terminal holding device (door closing force holding device) 71 that holds the car door 31 at the closed position by physical resistance, a controller (control unit) 58 (which may include a microcomputer) that controls opening and closing of the car door 31, and position detection. and an emergency power supply device 70 that supplies power to the car 3 in the event of a power failure. However, the component part 50 is not limited to the parts listed above, but is a part that constitutes the door operator 5 and generates a driving force and a biasing force for driving the car door 31 to open and close and to hold the door open and closed. , transmission, and control of these, safety measures for the car door 31 (prevention of unintentional opening and closing), and various structural parts and electrical parts that function in relation to the opening and closing of the car door 31 in normal or emergency situations. . The same applies to the door operator 5 for opening and closing the landing door 41, which will be described later. Among the plurality of components 50, electrical components that are related to each other are connected by electric wires or the like.

In this elevator 1, the vertical surface 32 belonging to the car 3 is, for example, the inner surface of the car 3 and is located above the car door 31 (see FIG. 1). Specifically, of the vertical surfaces 32 belonging to the car 3 , the surface on which the storage section 6 is provided is above the car door 31 and adjacent to the car door 31 . A vertical plane 42 belonging to the hall 4 is also similar to the vertical plane 32 , for example, it is the outer surface of the hall 4 and is located above the hall door 41 . Specifically, a vertical plane 42 belonging to the landing 4 is above and adjacent to the landing door 41 .

The vertical plane 32 is, for example, a plane having the same height as the planes positioned on the left and right sides of the car door 31 and the landing door 41. It may not be necessary, and it may be a surface that protrudes toward the front side or a surface that is recessed from the surfaces positioned on the left and right.

Further, the vertical surface 32 is flush with the surface forming the inner wall of the car 3 (the surface exposed to the internal space of the car 3), but may not be flush with the surface forming the inner wall of the car 3. For example, It may be a surface that is a predetermined distance from the surface forming the inner wall of the car 3 . Therefore, the rear surface of the storage portion 6 also corresponds to the vertical surface 32 .

The car door 31 and the landing door 41 each have four door panels that can be opened and closed in the opening/closing direction. Each of these four door panels has a vertically elongated rectangular panel shape. Further, the car door 31 and the landing door 41 are double doors.

Furthermore, in this elevator 1, the car door 31 or the landing door 41 includes a fast door and a slow door with different opening/closing speeds. Specifically, the car door 31 includes fast doors 310 and slow doors 311 with different opening/closing speeds, and the landing door 41 includes fast doors 410 and slow doors 411 with different opening/closing speeds.

The storage part 6 is box-shaped, for example. Further, the storage box 6 has an opening 60 that opens forward, which is the front side (the inner side of the car 3 ) with respect to the vertical plane 32 belonging to the car 3 . Incidentally, the explanation of "front and back" regarding the car 3 will be made in this direction. That is, the "rear" is the opposite of the "forward" and is the back side (the outside of the car 3 or the landing 4 side) with respect to the vertical plane 32. As shown in FIG. As for the landing 4, the front and rear direction is opposite to that of the car 3. For example, the storage section 6 includes a cover panel 61 capable of opening and closing the opening 60 of the storage section 6 . In this elevator 1, by closing the opening 60 of the storage section 6 with the cover panel 61 when maintenance is not performed, when rainwater flows into the hoistway 2, the rainwater that reaches the car 3 is stored. It is possible to prevent rain water from entering the part 6 and getting the component 50 of the door operator 5 wet.

More specifically, the storage unit 6 includes a box body 62 having one surface opened as an opening 60 and a cover panel 61 capable of opening and closing the opening 60 . The opening/closing mode of the cover panel 61 with respect to the box 62 is not particularly limited. For example, the cover panel 61 may be pivoted with respect to the box 62 to be opened and closed by hinge support. At this time, it is preferable that the open state of the cover panel 61 can be maintained by a stopper. Alternatively, the cover panel 61 may be detachable, and the open state may be achieved by removing the cover panel 61 from the box body 62 .

In the elevator 1 of the present embodiment, at least some of the plurality of component parts 50 of the door operator 5 (specifically, hangers 57) extend downward from the downwardly facing surface of the box 62. A possible gap is formed. Moreover, in this elevator 1 , the storage section 6 is provided in the car 3 .

Further, the storage portion 6 (specifically, the box 62) is arranged to protrude into the car 3 as shown in FIG. However, part or all of the storage portion 6 (specifically, the box 62) can be formed outside the car 3. In this case, the vertical surface 32 belonging to the car 3 is arranged in a recessed position relative to the inner surface of the other car 3 . The box 62 of the storage unit 6 is fixed to the car 3 with fasteners such as bolts.

The door operator 5 is a mechanism in which parts (components 50) for opening and closing the door (car door 31) are assembled. The set of components 50 of the door operator 5 includes a plurality of fixed parts 500, which are components 50 fixedly attached to the vertical plane 32 belonging to the car 3 (see FIG. 2). Each component 50 (fixed part 500) is smaller than the opening 60 of the storage section 6 when viewed from the front. Furthermore, the fixing components 500 that are fixedly attached are arranged in a state of being shifted from each other when viewed from the front (a state in which the contours of the fixing components 500 do not overlap when viewed in the front-rear direction).

According to the elevator 1 described above, since the fixed part 500 of the door operator 5 can be accessed from the front of the storage section 6, maintenance can be performed from the front of the car 3 without going up on the car 3. It can improve the safety of time. In addition, since the fixing parts 500 that are fixedly attached are displaced from each other when viewed from the front, only the fixing parts 500 that require maintenance can be attached/detached without considering the order of attachment/detachment. , work efficiency is high.

In this elevator 1, the door operator 5 is, for example, a car door operator 33 for opening and closing the car door 31 (see FIG. 2). As a result, in the elevator 1, maintenance of the car door operator 33 can be performed from inside the car 3, and the operator does not have to climb onto the car 3 or open the hall door 41 for maintenance. 1) Since it is unnecessary to access the car door operator 33 from the landing 4 with the stop position of the car 3 lowered from the floor position of the landing 4, the safety during maintenance can be improved. In addition, restoration to the original state from the maintenance work state can be performed quickly and safely.

Specifically, in the elevator 1 of the present embodiment, all the fixed fixed parts 500 of the car door operator 33 are attached directly to the vertical surface 32 . Here, the term “fixedly” is not limited to immovably fixed objects, and can reciprocate within a limited range at a set position (e.g., block 56, hanger 57) or rotate (e.g., pulleys 53, 54).

On the other hand, a part such as the drive belt 55 that functions by moving with respect to other parts (pulleys 53 and 54 in the case of the drive belt 55) cannot be fixedly attached. Not included. Further, the fixed parts 500 do not include parts for connecting the fixed parts 500 to each other, such as electric wires. Furthermore, the hanger 57 and the like are fixed to the surface that is essential to be lifted from the surface forming the inner wall of the car 3 (the surface exposed to the internal space of the car 3) from a functional point of view (for example, a function of supporting the car door 31 so that it can be opened and closed). The part 500 is mounted directly on a vertical surface 32 provided separately from said surface at a location remote from said surface.

Hanger 57 is attached to vertical surface 32 of block 56 . In this elevator 1 , the vertical plane 32 of the block 56 is parallel to the plane forming the inner wall of the car 3 . The block 56 is attached to the vertical surface 32 of the guide rail 51 (corresponding to the inner surface of the U-shaped cross section in this embodiment). In other words, the vertical plane 32 includes not only one plane but also multiple planes shifted in the front-rear direction. In this elevator 1 , a part of the vertical surface 32 of the guide rail 51 (the innermost portion of the cross-sectional shape) is parallel to the inner wall of the car 3 .

The dimension of the car door operator 33 in the opening/closing direction is equal to or smaller than the dimension of the car 3 in the opening/closing direction. It has become. The dimension of the car door operator 33 in the opening/closing direction may be slightly larger than the dimension of the car 3 in the opening/closing direction.

In the elevator 1 of the present embodiment, the operation direction for attachment/detachment or adjustment of the fixed part 500 with respect to the vertical surface 32 belonging to the car 3 is the front-rear direction with respect to the opening 60 of the storage section 6 . For example, the direction of operation for attaching and detaching the fixed part 500 to and from the vertical surface 32 of the car is, for example, the direction for tightening and loosening bolts. Note that the fixed component 500 in a state where it is not fixed from the vertical surface 32 only needs to move itself (in its entirety) forward and backward. One end and the other end may be slanted when it is put in and taken out of the opening 60 in a state in which the fixation from the surface 32 is released, and the fixing part 500 itself can be freely tilted or rotated. .

The adjustment of the fixed part 500 includes, for example, confirmation of looseness of bolts provided on the fixed part 500, operation of buttons necessary for maintenance of the fixed part 500, operation related to display confirmation of the fixed part 500, and electrical adjustment of the fixed part 500. Including at least one of the connections of the connector.

In this elevator 1, during maintenance, the fixing parts 500 of the door operator 5 can be attached, detached, and adjusted from the front-rear direction with respect to the opening 60 without complicating the components. Therefore, the operability of the operator is high during maintenance.

Further, in the elevator 1 of the present embodiment, in all the fixed parts 500 of the car door operator 33, the operation direction for attaching/detaching or adjusting the fixed parts 500 with respect to the vertical plane 32 belonging to the car 3 is the opening of the storage section 6. 60 is the front-rear direction. It should be noted that only some of the fixing components 500 to the extent that maintenance of the other fixing components 500 is not affected, the operation direction for attachment/detachment or adjustment with respect to the vertical surface 32 of the fixing components 500 is the opening 60 of the storage section 6. It is permissible not to be in a direction that is not forward or backward relative to .

Furthermore, in the elevator 1 of the present embodiment, the fixed part 500 includes the guide rail 51 that extends in the door opening/closing direction above the doorway of the car 3 and guides the door panel of the car door 31 . Specifically, the fixed part 500 is connected to one guide rail 51 that guides the opening and closing of both the fast door 310 and the slow door 311, and to each of the fast door 310 and the slow door 311. By being surrounded by the guide rails 51 (see FIGS. 3(a) and 3(b)) or by sandwiching the guide rails 51 (relationship between inside and outside of FIGS. 3(a) and 3(b)), and a block 56 attached to the guide rail 51 .

A guide rail 51 is attached to the vertical surface 32 . Further, the guide rail 51 is a single piece continuous in the longitudinal direction. The guide rail 51 has, for example, a U-shaped cross section, and in the present embodiment, is provided so as to open forward in the attached state (due to the arrangement of the blocks 56 and the like, the guide rail 51 is 51 can also be opened upwards or downwards). The attached block 56 is surrounded by the guide rail 51 so as to enter the internal space of the U-shaped portion of the guide rail 51 . As a result, one guide rail 51 guides the opening and closing of both the fast door 310 and the slow door 311, so the car door operator 33 can be made compact. Further, in this elevator 1, the guide rail 51 can be attached and detached in the front-rear direction during maintenance.

More specifically, in the elevator 1, a guide rail 51, a door motor 52 as a power source for opening and closing the car door 31, and a door motor 52 are mounted on the vertical plane 32 belonging to the car 3 as fixed parts 500 of the car door operator 33. A pair of drive pulleys 53 driven by and a pair of driven pulleys 54 driven by the drive pulleys 53 are attached. Further, as another component 50, a pair of drive belts 55 are provided which are respectively hung on a pair of drive pulleys 53 or a pair of driven pulleys 54. As shown in FIG.

In the elevator 1 of this embodiment, other components 50 (500) (for example, a door motor 52, a drive pulley 53, a driven pulley 54, and a drive belt 55) are attached to the guide rail 51, and one A guide rail 51 guides the opening and closing of both the fast door 310 and the slow door 311 . Therefore, the components 50 (500) (for example, the door motor 52, the driving pulley 53, the driven pulley 54, and the driving belt 55) attached to the guide rail 51 can be attached and detached at once in one operation during maintenance. Therefore, compared with the case where the fast door 310 and the slow door 311 are separately provided on the guide rail 51, maintenance can be easily performed.

A block 56 guided by the drive belt 55 and traveling along the guide rail 51 and a hanger 57 connecting the block 56 and the car door 31 are attached to the vertical surface 32 as fixed parts 500 . The blocks 56 are provided with guide rollers (not shown), and the guide rollers rotate with respect to the guide rails 51 so that the blocks 56 can run smoothly with respect to the guide rails 51 . The hanger 57 can reciprocate along the guide rail 51 while suspending the door panel of the car door 31 (for example, the fast door 310 or the slow door 311).

The hanger 57 suspending the fast door 310 and the hanger 57 suspending the slow door 311 are arranged so that the moving range along the longitudinal direction of the guide rail 51 accompanying opening/closing of the doors 310 and 311 does not overlap. Specifically, the hanger 57 suspending the fast door 310 reciprocates in the inner range of the guide rail 51 , and the hanger 57 suspending the slow door 311 reciprocates in the outer range of the guide rail 51 . Since the fast door 310 and the slow door 311 are displaced in the front-rear direction, the hanger 57 for the fast door 310 and the hanger 57 for the slow door 311 have different shapes. Further, the attachment position of the fast door 310 to the hanger 57 for the fast door 310 is offset in the longitudinal direction from the attachment position of the slow door 311 to the hanger 57 for the slow door 311 .

Also, the block 56 of this embodiment has a retractable movable piece (not shown) on its side surface. It is possible to pass through the opening in front of the guide rail 51 with the movable piece retracted. By protruding the movable piece, the longitudinal movement of the block 56 with respect to the guide rail 51 is allowed while the longitudinal movement thereof is restricted. With this configuration, the block 56 can be attached and detached by moving the block 56 in the front-rear direction with respect to the guide rail 51 and the vertical surface 32 .

Furthermore, a controller (control unit) 58 connected to the door motor 52, an inverter 59, an emergency power supply device 70, and a terminal holding device (door closing force holding device) 71 are attached as fixed parts 500 to the vertical surface 32. be done.

In this elevator 1, as shown in FIGS. 3(a) and 3(b), a device for detecting whether the car door 31 is fully open or fully closed is housed within the guide rail 51. As shown in FIG.

For example, the fixing component 500 includes a terminal fixing block 64 provided at the end of the guide rail 51 on the door opening side, and a door open position detector 65 arranged in the terminal fixing block 64 (FIG. 3(a)). )reference). The door open position detector 65 is a push switch that switches between on and off when a button is pushed. The block 56 interlocked with the car door 31 to be opened (specifically, the slow door 311) pushes the button of the door open position detector 65, turning on the door open position detector 65, thereby opening the car door 31. Full open is detected.

The fixed component 500 also includes a central fixed block 66 provided at the end of the guide rail 51 on the door-closing side, and a door-closed position detector 67 arranged in the central fixed block 66 (Fig. 3(b)). ) A). The door closed position detector 67 is a push switch that switches between on and off when a button is pushed. The block 56 interlocked with the car door 31 to be closed (specifically, the fast door 310) pushes the button of the door closed position detector 67, and the door closed position detector 67 is turned on, so that the car door 31 is closed. fully closed is detected.

In addition, the elevator of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention. For example, the configuration of one embodiment can be added to the configuration of another embodiment, and part of the configuration of one embodiment can be replaced with the configuration of another embodiment. Furthermore, some of the configurations of certain embodiments can be deleted.

For example, the elevator 1 accommodates a door operator 5 for opening and closing the car door 31 or the landing door 41, and the component parts 50 of the door operator 5. and a storage portion 6 provided on a component mounting surface 42 positioned above the doorway of the door. Further, the door operator 5 may include a door opening/closing device for opening and closing the car door 31 or the landing door 41 and a door guide rail 51 for guiding the car door 31 or the landing door 41 . That is, the elevator 1 includes a landing door operator for opening and closing a landing door 41, and a storage unit 6 provided on a part mounting surface 42 positioned above the entrance/exit of the landing 4 and storing components 50 of the landing door operator. may have only In addition, the elevator 1 includes both a car door operator for opening and closing the car door 31 and a landing door operator for opening and closing the landing door 41, and a part mounting surface 32 located above the doorway of the car 3. Both the storage part 6 that is installed and stores the component parts 50 of the car door operator and the storage part 6 that is provided on the part mounting surface 42 located above the doorway of the landing 4 and stores the component parts 50 of the landing door operator. and may be provided.

FIG. 4 shows a configuration in which the door operator 5 is a landing door operator 34 for opening and closing the landing door 41 and the storage section 6 is provided on a vertical plane 42 belonging to the landing 4 . In this elevator 1, the maintenance of the hall door operator 34 can be performed from the front of the hall 4, and the worker does not need to go up on the car 3 for the maintenance, so that the safety during the maintenance can be improved. Note that the cover panel 61 may be provided on the hoistway 2 side so that maintenance can be performed from the hoistway 2 side.

Specifically, in the elevator 1, a guide rail 51 and two pairs of driven pulleys that are rotated by the driving force of the car door operator 33 are transmitted to the vertical plane 42 belonging to the hall 4 as fixed parts 500 of the hall door operator 34. 54 is attached. Further, as another component 50, a pair of driving belts 55 are provided which are respectively hung on two pairs of driven pulleys 54. As shown in FIG. Furthermore, a block 56 guided by a drive belt 55 and traveling along the guide rail 51 and a hanger 57 connecting the block 56 and the car door 31 are attached to the vertical surface 42 as fixed parts 500 . Further, on the vertical surface 42, as fixing parts 500, an end holding device (door closing force holding device) 71, a door closing force assisting spring 72 for holding the door closed state, and a landing door 41 are locked in a fully closed state. and an interlock 68 for checking the closed state of the landing door 41 and a door closing confirmation device 69 for confirming the closed state of the landing door 41 are attached. One door-closing force assisting spring 72 is arranged, for example, between one block 56 for the fast door 410 and the central position in the opening/closing direction of the landing door operator 34 .

Further, in this elevator 1, as shown in FIG. Interlock 68 comprises a lever 681 supported on block 56 . The lever 681 moves in conjunction with opening and closing of the landing door 41 . The door closing confirmation device 69 has, for example, a button switch 690 and a movable plate 691 provided above the button switch 690 .

In this interlock 68, when the landing door 41 is closed, the tip of the lever 681 pushes down the plate 691, and the plate 691 pushes the button switch 690, turning the button switch 690 on. This confirms that the landing door 41 is in the closed state. On the other hand, when the landing door 41 opens, the tip of the lever 681 moves upward and separates from the plate 691, the plate 691 separates from the button switch 690, and the button switch 690 is turned off. This confirms that the landing door 41 is in the open state.

In the elevator 1 of the above-described embodiment, one guide rail 51 is configured to guide the opening and closing of both the fast door 310 and the slow door 311, but a pair of (two) guide rails are provided for each fast door 310. Alternatively, the opening/closing of the slow door 311 may be guided. In this case, the pair of guide rails may be arranged side by side in the vertical direction (not in the front-rear direction). Even with this configuration, the door operator 5 can be made compact when viewed from the horizontal direction.

Note that the guide rail 51 is not limited to one that is continuous in the longitudinal direction, but may be divided in the longitudinal direction and configured to function as one after being attached to the vertical surface 32 .

In the above-described embodiment, the component mounting surface 32 is the vertical surface 32, but the entire component mounting surface 32 may be a surface inclined with respect to the floor surface direction. In this case, the hanger 37 that connects the block 56 and the car door 31 may be deformed so as to provide a folding angle so that the car door 31 is oriented perpendicular to the floor surface direction. In this configuration, the fixing components 500 attached to the inclined component mounting surface 32 are arranged in a state of being shifted from each other when viewed from the front (in a direction perpendicular to the component mounting surface 32). If there is, it is possible to access the components 50 of the door operator 5 from the front of the storage unit 6 (in the direction perpendicular to the component mounting surface 32). Maintenance can be performed from the front of 4, and safety during maintenance can be improved. Furthermore, if the component mounting surface 32 is a surface inclined downward at an angle greater than 0° and within 45° downward with respect to the floor surface direction (a surface inclined obliquely downward), the component 50 can be easily attached and detached during maintenance. It can be carried out.

Further, if the operation direction for attachment/detachment or adjustment of the fixed component 500 with respect to the inclined component mounting surface 32 is the front-rear direction with respect to the opening 60, the front-rear direction with respect to the opening 60 (component The component parts 50 of the door operator 5 can be attached, detached, and adjusted from the direction perpendicular to the mounting surface 32) without complicating the component parts 50 with each other. It should be noted that the direction perpendicular to the component mounting surface 32 is, for example, a direction that is inclined downward within a range of 45° with respect to the horizontal plane.

Further, the car door 31 and the landing door 41 are double-opening doors including fast doors and slow doors with different opening/closing speeds, but they may be single-opening doors. Further, although the car door 31 and the landing door 41 have four double-opening doors, they may have a plurality of double-opening or single-opening doors such as two, three, or five or more doors. If the structure has a plurality of doors, one guide rail 51 is configured to guide the opening and closing of the plurality of doors, or a plurality of guide rails that guide the opening and closing of each door are arranged vertically. By arranging them side by side, the door operator 5 can be made compact. The car door 31 and the landing door 41 may have a single door that opens to one side.

The car 3 may be provided with a door pocket that accommodates the opened car door 31 . For example, the door pocket is integrally provided on the outer surface side of the car 3 . By providing the door pocket in the car 3, the internal space of the car 3 is not occupied by the car door 31, so that the internal space of the car 3 can be widened. Further, when the car 3 is provided with a door pocket and the guide rail 51 is provided on the door pocket, the storage portion 6 can be provided from the inside of the car 3 over the door pocket.

Although the elevator 1 is an elevator in which the car 3 and the lifting mechanism are integrated, the present invention can also be applied to an elevator in which the car 3 and the lifting mechanism can be separated. In particular, when the car 3 is separated from the lifting mechanism and used so as to be exposed to the outside of the hoistway 2, the door operator 5 is not exposed to the outside of the car 3 and is placed inside the car 3 in a state of being housed in the storage section 6. By doing so, the appearance of the car 3 can be made beautiful. Further, when a door pocket for housing the car door 31 is provided, the car door 31 when opened can be housed in the door pocket.

In the elevator 1 of the above-described embodiment, the storage section 6 has a box shape, but may have another configuration. For example, the storage section 6 may be a storage space inside the car 3 or at the landing 4 . In this case, the component 50 attached to the component mounting surfaces 32 and 42 may be accommodated in this storage space and covered with an openable/closable cover panel 61 .
