Description

  The present invention relates to an elevator hall door device provided at a hall of each floor and having an auto closer function for automatically closing a door panel, and an opening / closing device thereof.

In a general elevator hall door device, a closer weight is connected to a door panel via a wire, and the door panel is pulled in the closing direction by the weight of the closer weight. And, for example, during maintenance work, the door panel is manually opened by the maintenance worker, and then restrained in the open state by the maintenance worker. When the restraint is released, the door panel in the open state is released by the tensile force from the closer weight. Is moved in the closing direction. Here, since this closer weight is raised and lowered with the opening and closing movement of the door panel, it is necessary to install a weight guide mechanism or the like for guiding the raising and lowering of the weight, and the installation area of the entire apparatus has been increased.
In contrast, in a conventional elevator door closer device, one end of the spiral spring is fixed to the end of the header (plate member) on the closed position side, and the other end of the spiral spring is on the closed position side of the high-speed door. It is fixed to the end of the. This spiral spring extends in the opening direction and stores restoring force when the door panel is opened. When the maintenance worker is restrained in the open state and the restraint is released, the high-speed door at the open position is moved in the closing direction by the restoring force of the spiral spring. At the same time, the restoring force of the spiral spring is transmitted to the low-speed door via the interlocking means, and the low-speed door is also moved in the closing direction (see, for example, Patent Document 1).
Moreover, in the conventional elevator apparatus, the guide rail which guides the opening and closing movement of the door panel is disposed so as to be inclined downward from the opening side of the door panel to the closing side. When the maintenance worker is restrained in the open state and the restraint is released, the door panel at the open position is moved in the closing direction by gravity acting on the door panel (see, for example, Patent Document 2).

JP-A-10-279235 JP 2003-104668 A

In the conventional elevator door closer device as shown in Patent Document 1, when the door panel is in a fully open state, the spiral spring extends over the entire movement range of the door panel, so that the elastic fatigue of the spiral spring during normal use is sufficient. It is necessary to consider. In addition to this, it is necessary to satisfy the specifications such as the durability of the spiral spring after fully considering the material of the spiral spring and individual differences in performance (manufacturing variation). In order to ensure high reliability (for defects), it was necessary to strictly set the required specifications for the spiral spring, and the manufacturing cost was high.
Moreover, in the conventional elevator apparatus as shown to patent document 2, a door panel is moved up and down by the quantity according to the inclination angle of a guide rail with the opening / closing operation | movement of a door panel. A guide mechanism that guides the opening and closing movement of the lower part of the door is provided below the landing threshold so as to correspond to the vertical movement of the door panel, and the lower part of the door is more than the other part by the amount of movement in the vertical direction of the door. It is getting thinner. As described above, since the guide mechanism is disposed below the landing threshold, work efficiency during assembly / disassembly is reduced, and time and effort are required during installation and maintenance.

  The present invention has been made to solve the above-described problems, and can automatically close the door panel with a compact and inexpensive configuration, and can improve the work efficiency during assembly and disassembly. An object is to obtain an elevator hall door device and its opening / closing device.

  The elevator landing door device opening and closing device according to the present invention guides the opening and closing movement of the door panel that opens and closes the landing doorway, and also causes the door panel to self-close, and is provided above the landing doorway on the inner wall of the hoistway, In addition, a hanger rail that is inclined downward from the open side to the closed side of the door panel and guides the opening and closing movement of the door panel, and a plurality of hanger rollers that are fixed to the top of the door panel and that can rotate on the hanger rail are arranged in the inclination direction of the guide rail. There is a door hanger that is provided at an interval and suspends the door panel from the hanger rail, and a guide shoe that is provided on the upper surface of the landing sill and that is inserted into a guide groove along the door panel opening and closing direction. On the other hand, a panel leg mechanism slidable in the vertical direction is provided.

  In the elevator landing door device opening and closing device according to the present invention, the hanger rail on which the door panel is suspended is disposed so as to be inclined downward from the opening side to the closing side of the door panel, and the panel leg mechanism slides in the vertical direction with respect to the door panel. Since it is possible, the door panel can be self-closed with a compact and inexpensive configuration by not using a conventional closer weight or spiral spring. At the same time, when the door panel moves in the opening direction, the height position of the panel leg mechanism is maintained even if the door panel moves upward along the hanger rail, and a conventional guide mechanism is arranged below the sill member. By eliminating the need to do so, the work efficiency during assembly and disassembly can be improved.

Only one of the two-door panels 3 and 4 receives an opening / closing driving force from a door opening / closing driving device (not shown) provided on the car. The other of the first and second door panels 3 and 4 receives an opening / closing driving force from one of the first and second door panels 3 and 4 via an opening / closing synchronization mechanism.

  The first hanger rollers 18 are arranged at intervals in the inclination direction of the first hanger rail 8. The second hanger rollers 19 are arranged at intervals in the inclination direction of the second hanger rail 9. The cross-sectional shape of the outer peripheral portion of the first and second hanger rollers 18 and 19 is an arc shape curved so as to protrude toward the center in the circumferential direction, and corresponds to the cross-sectional shape of the first and second hanger rails 8 and 9. Yes. The first and second hanger rollers 18 and 19 are mounted on the first and second hanger rails 8 and 9 so as to be able to roll. Further, the first and second hanger rollers 18 and 19 are arranged such that when the first and second door panels 3 and 4 are in the open position, the first and second hanger rails 8 and 19 are caused by the weight of the first and second door panels 3 and 4. Roll on 9 in the closing direction. That is, when the first and second hanger rollers 18 and 19 roll on the first and second hanger rails 8 and 9 in the closing direction, the opened first and second door panels 3 and 4 move in the closing direction. .

  The first support rollers 20 are arranged below the first hanger rollers 18 at intervals from each other in the inclination direction of the first hanger rail 8. The second support rollers 21 are arranged below the second hanger rollers 19 at intervals from each other in the inclination direction of the second hanger rail 9.

  Here, elongated holes 14b and 15b extending in the vertical direction are provided at the attachment positions of the first and second support rollers 20 and 21 of the first and second door hangers 14 and 15, respectively. The attachment positions of the first and second support rollers 20 and 21 can be adjusted in the height direction by the long holes 14b and 15b. In addition, when the first and second door hangers 14 and 15 are installed, the first and second support rollers 20 and 21 are attached in advance to a low position (near the lower ends of the long holes 14b and 15b), and the first and second hanger rollers After 18 and 19 are disposed on the first and second hanger rails 8 and 9, the positions of the first and second support rollers 20 and 21 are adjusted in the height direction.

  A first panel leg mechanism 22 is provided between the panel first side surface portion 3 b and the panel second side surface portion 3 c at the lower portion of the first door panel 3. A second panel leg mechanism 23 is provided between the panel first side surface portion 4 b and the panel second side surface portion 4 c at the lower portion of the second door panel 4. Each of the panel leg mechanisms 22, 23 has a plate-like slide side panel 24, a plurality of guide shoes 25, and a plurality of slide rollers 26.

  The upper end of the guide shoe 25 is fixed to the lower surface of the slide side panel 24. The lower end portion of the guide shoe 25 is slidably inserted into the guide groove 6a. The guide shoe 25 slides in the guide groove 6a as the door panels 3 and 4 are opened and closed. That is, the first and second panel leg mechanisms 22 and 23 guide the opening and closing movement of the first and second door panels 3 and 4 together with the first and second hanger rails 8 and 9.

  Each slide roller 26 is disposed adjacent to each side surface portion 3b, 3c, 4b, 4c at both ends in the horizontal direction of the slide side panel 24. Further, the slide rollers 26 are arranged at intervals in the height direction. That is, at least two slide rollers 26 are disposed at both ends of the slide side panel 24. A retaining structure (not shown) for preventing each slide roller 26 from dropping off to the hoistway side (front side in the figure) at a position adjacent to each slide roller 26 of each side surface portion 3b, 3c, 4b, 4c. Is provided. That is, each slide roller 26 rotates only in the vertical direction with respect to each side surface portion 3b, 3c, 4b, 4c. By the slide rollers 26, the slide side panels 24 of the first and second panel leg mechanisms 22, 23 slide in the vertical direction with respect to the first and second door panels 3, 4.

  The first and second door panels 3 and 4 and the first and second panel leg mechanisms 22 and 23 are connected to each other via a plurality of downward biasing elastic bodies 27 serving as vertical synchronization mechanisms. The downward biasing elastic body 27 is, for example, a constant load spring or a mainspring spring. One end of each downward biasing elastic body 27 is fixed to the lower part of the first and second door panels 3 and 4, and the other end of each downward biasing elastic body 27 is connected to each slide side panel. 24 is fixed to the upper surface. Further, each downward biasing elastic body 27 biases each slide side panel 24 downward from each door panel 3, 4. That is, the downward biasing elastic body 27 moves each slide side panel 24 up and down with respect to the vertical movement of the first and second door panels 3 and 4 in synchronization with the vertical movement of the first and second door panels 3 and 4. Slide in the opposite direction. In addition, since a downward force is exerted on each slide side panel 24 by its own weight, the urging force of each downward urging elastic body 27 is sufficiently larger than the force in the opening / closing direction applied to the first and second door panels 3 and 4. The first and second door panels 3 and 4 are set so as not to hinder the movement in the closing direction.

  Next, the operation will be described. First, when the first and second door panels 3 and 4 in the closed state receive a driving force in the opening direction by the door opening and closing drive device, the first and second door panels 3 and 4 move in the opening direction along the first and second hanger rails 8 and 9 and move upward. Move to. As the first and second door panels 3 and 4 move upward, each slide-side panel 24 maintains its height position by its own weight and the spring force of each downward biasing elastic body 27. It slides downward relative to the first and second door panels 3 and 4. On the other hand, when receiving the driving force in the closing direction by the door opening / closing drive device, the first and second door panels 3 and 4 in the opened state move along the hanger rails 8 and 9 in the closing direction and move downward. As each door panel 3, 4 moves downward, each slide-side panel 24 maintains the height position against the spring force of each downward biasing elastic body 27, while maintaining the height position. It slides upward with respect to the door panels 3 and 4.

  For example, when the first and second door panels 3 and 4 are opened by an operator during maintenance work, for example, an opening fixing tool (not shown) is attached to the first and second door panels 3 and 4. The open state of the first and second door panels 3 and 4 is restrained. The first and second door panels 3 and 4 in the constrained state receive a force in the closing direction due to the inclination of the first and second hanger rails 8 and 9 and the weight of the first and second door panels 3 and 4. It is hanging. Then, when the opening and fixing device is removed from the first and second door panels 3 and 4 and the restrained state is released, the first and second hanger rails are moved by the weight of the first and second door panels 3 and 4. It moves in the closing direction and moves downward along 8, 9 (self-closing).

  In the opening / closing device of the elevator hall door device as described above, the first and second hanger rails 8 and 9 on which the first and second door panels 3 and 4 are respectively suspended are inclined downward from the open position side to the closed position side. Since the first and second panel leg mechanisms 22 and 23 are slidable in the vertical direction with respect to the first and second door panels 3 and 4, respectively, the conventional closer weight and biasing force can be reduced. By not using a large spiral spring, the first and second door panels 3 and 4 can be self-closed with a compact and inexpensive configuration. At the same time, when the first and second door panels 3 and 4 move in the opening direction, the first and second door panels 3 and 4 move upward along the first and second hanger rails 8 and 9, respectively. The height positions of the first and second panel leg mechanisms 22 and 23 are maintained, and it becomes unnecessary to dispose a conventional guide mechanism below the sill member, thereby improving work efficiency during assembly and disassembly. be able to.

Moreover, in the conventional elevator apparatus as shown in Patent Document 2, the clearance between the car sill and the landing sill is set to be equal to the clearance between the car sill and the landing sill in the elevator apparatus using the closer weight. The two doors are a car door and a landing door. As a result, the gap dimension between the landing sill and the car sill becomes wider than the gap dimension in the elevator apparatus using the closer weight, and induces the user to get on and off the car.
On the other hand, in the opening / closing device of the elevator hall door device as described above, it is not necessary to arrange a guide mechanism as shown in Patent Document 2 below the hall sill 6, so that the hall sill 6 and the car sill are The clearance dimension between them can be set to be equal to the clearance dimension in an elevator apparatus using a closer weight.

  In the first embodiment, the first and second door panels 3 and 4 and the first and second panel leg mechanisms 22 and 23 are connected to each other by the downward biasing elastic body 27. However, the present invention is not limited to this example. If the friction coefficient of each slide roller with respect to each side surface is sufficiently small and each panel leg mechanism can slide with respect to each door panel with its own weight, the downward biasing elastic body 27 is omitted. May be.

  In the first embodiment, the first and second hanger rails 8 and 9 have a cross-sectional shape and the first and second hanger rails 8 and 9 so that the first and second hanger rails 14 and 15 are not detached from the first and second hanger rails 8 and 9. 2 The cross-sectional shapes of the outer peripheries of the hanger rollers 18 and 19 are each arcuate, but the present invention is not limited to this example, and these shapes may be any shape that fits each other. Also good. However, in this case, in order to prevent foreign matter from getting caught, it is preferable that the cross-sectional shapes of the first and second hanger rails 8 and 9 are substantially triangular so that the apex protrudes upward.

Embodiment 2. FIG.
Next, a second embodiment of the present invention will be described. FIG. 3 is a rear view showing the elevator hall door device according to the second embodiment. 4 is a rear view showing the fully opened state of the first and second door panels 3 and 4 of FIG. FIG. 3 shows the fully closed state of the first and second door panels 3 and 4. On the lower surfaces of the first and second hanger rails 8 and 9 of the second embodiment, tooth-shaped rack surfaces 8a and 9a are formed. Further, the first and second panel leg mechanisms 22 and 23 of the second embodiment do not have the downward biasing elastic body 27 in the first embodiment, and the first and second panel leg mechanisms 22 and 23. The first and second vertical synchronization mechanisms 28 and 29 are connected to the two, respectively.

  The first and second vertical synchronization mechanisms 28 and 29 have first and second rod-like portions 30 and 31 and first and second pinions 32 and 33, respectively. The lower end of the rod-shaped portion 30 is fixed to the upper surface of the slide side panel 24. The upper ends of the first and second rod-shaped portions 30 and 31 are disposed in the vicinity of the central portions of the first and second door hangers 14 and 15. A tooth-shaped first rack portion is provided on the open side (left side in the drawing) of the first door panel 3 at the upper end portion of the first rod-shaped portion 30. Furthermore, a tooth-shaped second rack portion is provided on the open side (right side in the drawing) of the second door panel 4 at the upper end portion of the second rod-shaped portion 31. Cutouts (sliding grooves) for sliding the first and second rod-shaped portions 30 and 31 are provided at the center in the length direction of the upper surface portions 3a and 4a of the panels and the lower surface portions 14a and 15a of the hangers, respectively. .

  The first and second pinions 32 and 33 are rotatably attached to the first and second door hangers 14 and 15. Each pinion 32 and 33 has two gear parts, a hoistway side gear part and a landing side gear part. That is, gear portions are arranged on both the front and back surfaces of the first and second pinions 32 and 33. The hoistway side gear portion and the landing side gear portion rotate integrally with each other. The hoistway side gear portions of the first and second pinions 32 and 33 are engaged (engaged) with the rack portions of the first and second rod-like portions 30 and 31, respectively. The landing side gear portions of the first and second pinions 32 and 33 are engaged with the first and second rack surfaces 8a and 9a, respectively.

  Here, when the first and second door panels 3 and 4 are opened and closed, the first and second pinions 32 and 33 are rotated, and the first and second rod-shaped portions 30 and 31 are moved to the first and second door hangers 14. , 15 slides up and down. As the first and second rod-shaped portions 30 and 31 slide, the slide side panel 24 slides in the vertical direction with respect to the first and second door panels 3 and 4 while maintaining the height position. Move. That is, the first and second vertical synchronization mechanisms 28 and 29 are rack and pinion mechanisms, and open and close movements of the first and second door panels 3 and 4 and slide sides of the first and second panel leg mechanisms 22 and 23. The sliding of the panel 24 is synchronized with each other.

  Next, the operation will be described. First, when the closed first door panel 3 moves in the opening direction, the first pinion 32 rotates clockwise in the figure, and the first bar 30 slides downward with respect to the first door hanger 14, As the first bar 30 slides, the first panel leg mechanism 22 (slide side panel 24) slides downward relative to the first door panel 3. On the other hand, when the opened first door panel 3 moves in the closing direction, the first pinion 32 rotates counterclockwise in the figure, and the first bar 30 slides upward with respect to the first door hanger 14. As the first bar 30 slides, the first panel leg mechanism 22 slides upward with respect to the first door panel 3. The operation of the second door panel 4 is the same as the operation of the first door panel 3 except that the rotation direction of the second pinion 33 is opposite to the rotation direction of the first pinion 32.

  In the opening / closing device of the elevator hall door device as described above, the first and second door panels 3, 4 are opened / closed and the first and second panel leg mechanisms 22, 23 by the first and second vertical synchronization mechanisms 28, 29. Since the sliding of the slide side panel 24 is synchronized with each other, the same effect as that of the first embodiment can be obtained, and the slide side panel 24 can be slid more reliably and can be reliable for malfunctions. Can be improved.

  Here, in the first embodiment, when the door panels 3 and 4 are moved in the closing direction, the panel leg mechanisms 22 and 23 are biased downward (although the influence is small) from the panel leg mechanisms 22 and 23 to the first and second door panels 3 and 4. The resistance against the spring force of the elastic body 27 and the frictional force of the slide roller 26 acted. However, in the opening / closing device for an elevator hall door device as described above, the first and second door panels 3 and 4 are closed. Since the force applied to the first and second door panels 3 and 4 becomes the frictional force of the slide roller 26 during the movement, the gravity component applied to the first and second door panels 3 and 4 can be used more efficiently. The open first and second door panels 3 and 4 can be moved more smoothly in the closing direction.

  In the second embodiment, the first and second pinions 32 and 33 and the first and second rod-shaped portions 30 and 31 are engaged with each other, but a gear is attached to the first and second support rollers 20 and 21. Then, the gear and each rod-like portion 30, 31 may be engaged with each other.

  In the second embodiment, the vertical synchronization mechanisms 28 and 29 are configured by the first and second rod-shaped portions 30 and 31 and the first and second pinions 32 and 33. However, the present invention is not limited to this example. The door-side pinion having the first tooth portion and the second tooth portion is fixed to the first and second door panels 3 and 4 so as to be rotatable, and the first tooth portion of the door-side pinion, 2 pinions 32 and 33 (or the first and second support rollers 20 and 21) are connected by a timing belt or the like, and the second tooth portion of the door-side pinion and the rod-like portions 30 and 31 are engaged with each other. The vertical synchronization mechanisms 28 and 29 can be configured.

  Furthermore, although the center open type first and second door panels 3 and 4 are used in the first and second embodiments, side open type (one-sided type) high speed side and low speed side door panels may be used.

  Furthermore, in Embodiments 1 and 2, the two door panels of the first and second door panels 3 and 4 are used, but four or more (two or more on one side) door panels of the center open type may be used. .

Embodiment 3 FIG.
Next, a third embodiment of the present invention will be described. FIG. 5 is a rear view showing the elevator hall door device according to the third embodiment. 6 is a rear view showing the fully opened state of the first and second door panels 3 and 4 of FIG. FIG. 5 shows a fully closed state of the first and second door panels 3 and 4. The first and second panel leg mechanisms 22 and 23 of the first embodiment have the downward biasing elastic body 27, but the first and second panel leg mechanisms 22 and 23 of the third embodiment are The downward biasing elastic body 27 is not provided. In the first and second embodiments, at least four slide rollers 26 are attached to the slide side panel 24, but in the third embodiment, only two slide rollers 26 are attached to the slide side panel 24. . These slide rollers 26 are arranged at upper corners at both ends in the length direction of the slide side panel 24.

  Between the outer frame 13 side of the first and second door panels 3, 4 in the fully opened state and the outer frame 13 (the storage area of the first and second door panels 3, 4), there is a gap from the upper surface of the landing sill 6. In addition, a fixed-side lower slide rail 34 is provided. The fixed-side lower slide rail 34 is disposed along the opening / closing direction of the first and second door panels 3 and 4. A movable lower slide rail 35 is slidably provided on each fixed lower slide rail 34. One end of the movable side lower slide rail 35 is fixed to the slide side panel 24. Cutouts for sliding the movable-side lower slide rail 35 are provided at the lower end of the panel first side surface portion 3b of the first door panel 3 and the lower end of the panel second side surface portion 4b of the second door panel 4, respectively. . Each movable lower slide rail 35 slides along each fixed lower slide rail 34.

  That is, the fixed-side lower slide rail 34 and the movable-side lower slide rail 35 constitute a vertical synchronization mechanism, and the displacement of the slide-side panel 24 in the vertical direction is determined by the fixed-side lower slide rail 34 and the movable-side lower slide rail. Thus, the height position of the slide side panel 24 is maintained when the first and second door panels 3 and 4 are opened. Other configurations and operations are the same as those in the first embodiment.

  In the opening / closing device for the elevator hall door device as described above, the height position of the slide-side panel 24 is maintained by the fixed-side lower slide rail 34 and the movable-side lower slide rail 35. Therefore, the first embodiment and the second embodiment. In addition, the height position of the slide side panel 24 can be maintained with a simpler configuration than that of the second embodiment.

  In the first to third embodiments, the slide roller 26 is used as the sliding material. However, the sliding material is not limited to the sliding roller 26 and is a material having a sufficiently small friction coefficient. Any material that does not inhibit sliding may be used.

  In the first to third embodiments, the path of the transmission cable 11 is made to follow the inclination direction of the hanger rails 8 and 9 using the three idlers 12, but the inclination angles of the first and second hanger rails 8 and 9 are used. Is sufficiently small, the idler 12 may be omitted and the path of the transmission cable 11 may be horizontal. In addition, by making the mounting positions of the first and second gripping members 16 and 17 on the first and second door hangers 14 and 15 displaceable in the vertical direction, the idler 12 is omitted, and the path of the transmission cable body 11 May be horizontal.

Embodiment 4 FIG.
Next, a fourth embodiment of the present invention will be described. FIG. 7 is a rear view showing the elevator hall door device according to the fourth embodiment. FIG. 8 is a rear view showing the fully opened state of the high speed side and low speed side door panels 50 and 51 of FIG. In addition, in FIG. 7, the fully closed state of the high speed side and low speed side door panels 50 and 51 is shown. First, in the first to third embodiments, the first and second door panels 3 and 4 that are center open type doors are used. However, in the fourth embodiment, the high speed side that is a side open type (single door type) door and Low speed side door panels 50 and 51 are used.

  Similarly to the first and second door panels 3 and 4 in the first to third embodiments, the high-speed side and low-speed side door panels 50 and 51 are the panel upper surface portions 50a and 51a, the panel first side surface portions 50b and 51b, respectively. Two side portions 50c and 51c are provided. In the first to third embodiments, the first and second hanger rails 8 and 9 are used. However, in the fourth embodiment, the high speed side and low speed side hanger rails 52 and 53 are used. The high-speed side and low-speed side hanger rails 52 and 53 are inclined in parallel from the open side to the closed side of the high-speed side and low-speed side door panels 50 and 51 and are arranged in parallel to each other. Further, both end portions in the length direction of the high speed side and low speed side hanger rails 52 and 53 are connected to each other by a support pin 55.

  The high speed side door panel 50 is suspended from the high speed side hanger rail 52 via a high speed side door hanger 56. The low speed side door panel 51 is suspended from the low speed side hanger rail 53 via the low speed side door hanger 57. The structures of the high-speed side and low-speed door hangers 56 and 57 are the same as the structures of the first and second door hangers 14 and 15 in the third embodiment, respectively.

  A high speed side panel leg mechanism 58 is provided between the panel first side surface portion 50 b and the panel second side surface portion 50 c at the lower portion of the high speed side door panel 50. A low speed side panel leg mechanism 59 is provided between the panel first side surface portion 51 b and the panel second side surface portion 51 c at the lower portion of the low speed side door panel 51. The structures of the high speed side and low speed side panel leg mechanisms 58 and 59 are substantially the same as the structures of the first and second panel leg mechanisms 22 and 23 in the third embodiment, respectively.

  Here, the opening / closing movement amount of the high speed side door panel 50 is about twice the opening / closing movement amount of the low speed side door panel 51, and the vertical movement amount of the high speed side door panel 50 accompanying the opening / closing movement is also the vertical movement amount of the low speed side door panel 51. Approximately twice the amount of movement. For this reason, the height dimension of the slide side panel 24 of the high speed side panel leg mechanism 58 is larger than the height dimension of the slide side panel 24 of the low speed side panel leg mechanism 59. Further, the slide roller 26 of the high-speed side panel leg mechanism 58 is disposed at a position higher than the slide roller 26 of the low-speed side panel leg mechanism 59. That is, the sliding range of the slide side panel 24 of the high speed side panel leg mechanism 58 is larger than the sliding range of the slide side panel 24 of the low speed side panel leg mechanism 59.

  The high-speed side panel leg mechanism 58 further includes a plurality of protrusions 58 a that protrude upward from the upper surface of the slide-side panel 24. A movable inclined slide rail 60 is fixed to the upper end of each protrusion 58a. A fixed-side inclined slide rail 61 is attached to the second side surface portion 51 c of the low-speed side door panel 51. The movable side inclined slide rail 60 is slidable along the fixed side inclined slide rail 61. The movable-side inclined slide rail 60 and the fixed-side inclined slide rail 61 are inclined at the same inclination angle as that of the high-speed side and low-speed side hanger rails 52, 53 from the open side to the closed side of the high-speed side and low-speed side door panels 50, 51. It is inclined and arranged upward (opposite direction of the high speed side and low speed side hanger rails 52 and 53). The movable side inclined slide rail 60 and the fixed side inclined slide rail 61 restrict the displacement of the slide side panel 24 in the vertical direction of the high speed side panel leg mechanism 58.

  Between the outer frame 13 side of each door panel 50, 51 in the fully opened state and each outer frame 13 (the storage area of each door panel 50, 51), a fixed horizontal slide rail is spaced from the upper surface of the landing sill 6. 62 is provided. The slide side panel 24 of the low speed side panel leg mechanism 59 is provided with a movable side horizontal slide rail 63 slidable along the fixed side horizontal slide rail 62. The fixed side horizontal slide rail 62 and the movable side horizontal slide rail 63 restrict the displacement of the low speed side panel leg mechanism 59 in the vertical direction of the slide side panel 24.

  The slide rails 60 to 63 are slid at positions corresponding to the slide second rails 60 to 63 of the panel second side surface portion 50c of the high speed side door panel 50, the first side surface portion 51b of the low speed side door panel 51 and the second side surface portion 51c. A dynamic cutout is provided for each. The movable-side inclined slide rail 60 and the fixed-side inclined slide rail 61, and the fixed-side horizontal slide rail 62 and the movable-side horizontal slide rail 63 each constitute a vertical movement synchronization mechanism. Accordingly, the panel leg mechanisms 58 and 59 guide the opening and closing movement of the lower portions of the door panels 50 and 51 while maintaining the height position.

  Here, FIG. 9 is a rear view showing the interlocking mechanism 64 when the high-speed side and low-speed side door panels 50 and 51 are fully closed. FIG. 10 is a rear view showing the interlocking mechanism 64 when the high-speed side and low-speed side door panels 50 and 51 are fully opened. 9 and 10, the door panels 50 and 51, the hanger rails 52 and 53, and the rollers 18 to 21 are omitted. The door hangers 56 and 57 are connected to each other by an interlocking mechanism 64 provided above the door hangers 56 and 57. The interlocking mechanism 64 transmits the opening / closing driving force received by one of the high-speed side and low-speed side door panels 50, 51 to the other, and interlocks (synchronizes) the high-speed side and low-speed side door panels 50, 51 with each other.

  The interlocking mechanism 64 includes a pulley mounting plate (structure) 65, a pair of pulleys (pulleys) 66 and 67, a transmission cable body 68, and a gripping member 69. The pulley attachment plate 65 is attached to the upper part of the low speed side door hanger 57. The pulley mounting plate 65 has an extension 65a that extends from above the low-speed door hanger 57 in the fully closed state to above the high-speed door hanger 56 in the fully closed state. The extension part 65a is inclined and arranged along the inclination direction of the high-speed side and low-speed side hanger rails 52 and 53.

  The pulley 66 is rotatably attached in the vicinity of the tip of the extension portion 65a. The pulley 67 is rotatably attached to the door pocket side of the upper end portion of the pulley attachment plate 65. The transmission cable body 68 is bridged between the pulleys 66 and 67. Both end portions 68 a and 68 b of the transmission cable body 68 are fixed to an intermediate portion in the length direction of the plate member 7 at a distance from each other. The upper end portion of the gripping member 69 is connected to the transmission cable body 68. The lower end portion of the gripping member 69 is fixed to the high speed side door hanger 56. That is, the interlocking mechanism 64 is a moving pulley mechanism, and the moving amount of the high speed side door panel 50 is double the moving amount of the low speed side door panel 51 according to the principle of the moving pulley. Other configurations are the same as those of the third embodiment.

  Next, the operation of the interlocking mechanism 64 will be described. When the door panels 50 and 51 are fully closed, the high-speed side door panel 50 and the high-speed side door hanger 56 are moved to the open side by a driving force to the open side from a door opening / closing drive device (not shown). At this time, the connection portion of the transmission cable body 68 with the gripping member 69 is pulled to the open side, and both ends 68a and 68b of the transmission cable body 68 are fixed, whereby the pulleys 66 and 67 are rotated. The And since the connection location with the holding member 69 of the transmission cable body 68 is pulled to the open side, the pulley mounting plate 65 and each pulley 66 and 67 are also moved to the open side, and accordingly, the low speed side door panel 51. And the low speed side door hanger 57 is moved to the open side, and the door panels 50 and 51 are fully opened.

  Further, when the door panels 50 and 51 are fully opened, the high speed side door panel 50 and the high speed side door hanger 56 are moved to the closed side by the driving force from the door opening / closing drive device (not shown) to the closing side. At this time, the connection portion of the transmission cable body 68 with the gripping member 69 is pulled to the closed side, and both ends 68a and 68b of the transmission cable body 68 are fixed, whereby the pulleys 66 and 67 are rotated. The And since the connection location with the holding member 69 of the transmission cable body 68 is pulled to the closing side, the pulley mounting plate 65 and each pulley 66, 67 are also moved to the closing side, and accordingly, the low speed side door panel 51 is moved. And the low speed side door hanger 57 is moved to the closing side, and the door panels 50 and 51 are fully closed.

  In the elevator landing door opening and closing device as described above, the high-speed and low-speed panel leg mechanisms 58 and 59 guide the opening and closing movements of the lower portions of the high-speed door panel 50 and the low-speed door panel 51 while maintaining the height position. Even if it is a side open type door panel, the same effect as Embodiment 3 can be acquired.

  In the fourth embodiment, the interlocking mechanism 64 is provided above the door hangers 57 and 58, but is provided in a space on the back side of the door hangers 57 and 58 (the plate member 7 side of the high-speed door hanger 56). It's okay.

  In the fourth embodiment, the extension portion 65a is disposed so as to be inclined along the inclination direction of the high-speed side and low-speed side hanger rails 52, 53. However, the extension portion 65a may be disposed horizontally. In this case, the pulley mounting plate 65 and the gripping member 69 are provided with a slide mechanism (for example, by a long hole or a penetrating member) so that the pulley mounting plate 65 can be slid in the vertical direction with respect to the low speed side door hanger 57. 69 may be slidable in the vertical direction with respect to the high-speed hanger rail 52. By adopting such a configuration, the space efficiency above the door hangers 57 and 58 can be improved as compared with that of the fourth embodiment.

Embodiment 5 FIG.
Next, a fifth embodiment of the present invention will be described. FIG. 11 is a rear view showing the elevator hall door device according to the fifth embodiment. 12 is a rear view showing the fully opened state of the high speed side and low speed side door panels 50 and 51 of FIG. In addition, in FIG. 11, the fully closed state of each door panel 50 and 51 is shown. In FIGS. 11 and 12, the interlocking mechanism 64 is omitted. A third vertical synchronizing mechanism 70 is connected to the high-speed side panel leg mechanism 58 of the fifth embodiment. The third vertical synchronizing mechanism 70 includes an upper horizontal guide rail 71 provided on the hoistway side (front side in the figure) of the plate member 7, a rod-like portion 72 having a lower end connected to the upper surface of the slide side panel 24, and a plurality of guides A roller 73 is provided.

  The upper horizontal guide rail 71 is disposed along the opening / closing direction of the high speed side and low speed side door panels 50, 51. The cross-sectional shape of the upper horizontal guide rail 71 is substantially L-shaped. Further, the upper horizontal guide rail 71 has a vertical plane directed in the landing / hoistway direction and a horizontal plane perpendicular to the vertical plane in the horizontal direction. The upper end of the rod-like portion 72 is disposed adjacent to the upper horizontal guide rail 71 and faces the vertical surface of the upper horizontal guide rail 71. Moreover, the upper end of the rod-shaped part 72 is substantially T-shaped, and protrudes on both sides in the opening and closing direction of the high-speed side and low-speed side door panels 50 and 51. Each guide roller 73 is rotatably attached to a protruding portion at the upper end of the rod-like portion 72. The guide roller 73 is mounted on the horizontal plane of the upper horizontal guide rail 71 so as to be able to roll.

  That is, the guide roller 73 rolls on the horizontal plane of the upper horizontal guide rail 71 as the high-speed and low-speed door panels 50 and 51 are opened and closed, and the high-speed panel leg mechanism 58 slides through the rod-shaped portion 72. The height position of the side panel 24 is maintained. Other configurations and operations are the same as those in the fourth embodiment.

  Even in the case where the upper horizontal guide rail 71 is used in the opening / closing device of the elevator hall door device as described above, the same effects as those of the fourth embodiment can be obtained.

  In the fifth embodiment, the third vertical synchronization mechanism 70 is connected to the high-speed side panel leg mechanism 58. However, the third vertical synchronization mechanism 70 is a center-open type first and second door panels 3 and 4. May be connected to the first and second panel leg mechanisms 22, 23. That is, the third vertical synchronizing mechanism 70 can be applied to a center open type door.

Embodiment 6 FIG.
Next, a sixth embodiment of the present invention will be described. FIG. 13 is a rear view showing the elevator hall door device according to the sixth embodiment. 14 is a rear view showing the fully opened state of the high speed side and low speed side door panels 50 and 51 of FIG. FIG. 13 shows the fully closed state of the high speed side and low speed side door panels 50 and 51. In FIGS. 13 and 14, the interlocking mechanism 64 is omitted. First, in the fourth embodiment, the high-speed hanger rail 52 is inclined, but in the sixth embodiment, the high-speed hanger rail 52 is horizontal. Further, the inclination angle of the low-speed hanger rail 53 of the sixth embodiment is set to be twice the inclination angle of the low-speed hanger rail 53 of the fourth embodiment.

  Furthermore, the lower end of the high-speed side door panel 50 of the sixth embodiment is bent in a substantially L shape on the hoistway 1 side, and a lower surface portion 50d is formed. A plurality of guide shoes 25 in the first embodiment are attached to the lower surface portion 50d. That is, in the sixth embodiment, the high-speed panel leg mechanism 58 in the fourth and fifth embodiments is not used. In the sixth embodiment, the gripping member 69 of the interlocking mechanism 64 in the fourth embodiment is slidable in the vertical direction with respect to the high speed side door hanger 56. Other configurations are the same as those of the fourth embodiment.

  Next, the operation will be described. A force in the closing direction is applied to the open low-speed side door panel 51 by its own weight and the inclination of the low-speed side hanger rail 53, and the low-speed side door panel 51 moves in the closing direction. At this time, the force applied to the low speed side door panel 51 is transmitted to the high speed side door panel 50 via the interlocking mechanism 64, and the high speed side door panel 50 moves in the closing direction in conjunction with the low speed side door panel 51. Other operations are the same as those in the fourth embodiment.

  In the opening / closing device for the elevator hall door device as described above, even when only the low-speed hanger rail 53 is inclined, the same effect as in the fourth embodiment can be obtained. Further, since the high-speed side panel leg mechanism 58 in the fourth and fifth embodiments is not used, the number of parts can be reduced as compared with the fourth and fifth embodiments, and the number of parts can be reduced compared with the fourth and fifth embodiments. An inexpensive configuration can be obtained.

  In the sixth embodiment, the high-speed hanger rail 52 is horizontal and the low-speed hanger rail 53 is inclined. However, the high-speed hanger rail 52 may be inclined and the low-speed hanger rail 53 may be horizontal. .

Embodiment 7 FIG.
Next, a seventh embodiment of the present invention will be described. FIG. 15 is a rear view showing an elevator hall door device according to the seventh embodiment. 16 is a rear view showing the fully opened state of the high speed side and low speed side door panels 50 and 51 of FIG. FIG. 15 shows the fully closed state of the high-speed side and low-speed side door panels 50 and 51. 15 and 16, the interlocking mechanism 64 is omitted.

  In the fourth embodiment, the slide roller 26 and the support roller 20 are provided on the high-speed side door hanger 56, and the high-speed side hanger rail 52 is provided on the plate member 7. However, in the seventh embodiment, these are provided. The movable side support slide rail 74 is fixed to the high speed side door hanger 56. The movable support slide rail 74 is slidable along a fixed support slide rail 75 fixed to the low speed door hanger 57. The movable side and fixed side support slide rails 74 and 75 are arranged along the opening and closing directions of the high speed side and low speed side door panels 50 and 51. The high speed side door panel 50 is supported from the low speed side door hanger 57 via the movable side supporting slide rail 74 and the fixed side supporting slide rail 75.

  A first movable side lower slide rail 76 is fixed to the slide side panel 24 of the high speed side panel leg mechanism 58. A second movable side lower slide rail 77 is fixed to the slide side panel 24 of the low speed side panel leg mechanism 59. Between the outer frame 13 side and the outer frame 13 of the high-speed and low-speed door panels 50 and 51 in the fully opened state (the storage area of the high-speed and low-speed door panels 50 and 51), there is a gap from the upper surface of the landing sill 6. The fixed-side lower slide rail 78 is fixed. The first movable side lower slide rail 76 is slidable along the second movable side lower slide rail 77. The second movable side lower slide rail 77 is slidable along the fixed side lower slide rail 78.

  That is, the slide side panel 24 of the high speed side and low speed side panel leg mechanisms 58 and 59 is restricted from being displaced in the vertical direction by the lower slide rails 76 to 78. In addition, the support slide rails 74 and 75 and the lower slide rails 76 to 78 each constitute a vertical synchronization mechanism. In the seventh embodiment, the extension portion 65a of the interlocking mechanism 64 in the fourth embodiment is arranged horizontally. Other configurations are the same as those in the fourth embodiment.

  In the opening / closing device for the elevator hall door device as described above, the lower slide rails 76 to 78 restrict the displacement of the slide side panel 24 in the vertical direction of the high speed side and low speed side panel leg mechanisms 58 and 59. The same effects as in the fourth embodiment can be obtained. At the same time, instead of the high-speed side hanger rail 52 in the fourth embodiment, the movable-side and fixed-side support slide rails 74 and 75 that are half the movement amount of the high-speed side door panel 50 (2/3 of the lateral width of the plate member 7) are provided. Since it is used, it is possible to obtain a configuration that is more compact and lighter than that of the fourth embodiment. Further, common members can be used for the high-speed side and low-speed side door panels 50, 51 and the high-speed side and low-speed side panel leg mechanisms 58, 59, respectively, and productivity is improved, which is higher than that of the fourth embodiment. Furthermore, it can be set as a cheap structure.

Embodiment 8 FIG.
Next, an eighth embodiment of the present invention will be described. FIG. 17 is a plan view showing a part of the opening / closing device of the elevator hall door device according to the eighth embodiment. 18 is a rear view showing the high-speed side and low-speed side door hangers 56 and 57 of FIG. FIG. 19 is a plan view showing the high speed side and low speed side door hangers 56 and 57 of FIG. 17 with the high speed side and low speed side door panels 50 and 51 fully opened. 20 is a rear view showing the high-speed side and low-speed side door hangers 56 and 57 of FIG. 17 in a fully opened state of the door panel. 17 and 18 show the high-speed and low-speed door hangers 56 and 57 when the high-speed and low-speed door panels 50 and 51 are fully closed. 17-20, the structure below the high-speed side and low-speed side door hangers 56, 57 and the interlocking mechanism 64 are omitted.

  In the fourth embodiment, the high-speed and low-speed hanger rails 52 and 53 are arranged to be inclined with respect to the opening and closing directions of the high-speed and low-speed door panels 50 and 51. However, in the eighth embodiment, the high-speed and low-speed hanger rails 52 and 53 are arranged. The side hanger rails 52 and 53 are horizontally disposed along the opening and closing directions of the high speed side and low speed side door panels 50 and 51. In the eighth embodiment, the high speed side and low speed side panel leg mechanisms 58 and 59 are not provided below the high speed side and low speed side door panels 50 and 51, and the lower surface portions of the high speed side and low speed side door panels 50 and 51 are provided. Are attached with a plurality of guide shoes 25 in the first embodiment.

  The high speed side door hanger 56 has a high speed side hanger protrusion 56c that protrudes to the open side. The low speed side hanger 57 has a low speed side hanger protrusion 57c that protrudes toward the closing side. In a state where the door panels 50 and 51 close the hall entrance 2, the high speed side hanger protrusion 56 c and the low speed hanger protrusion 57 c face each other. In this state, the side end on the closed side of the low-speed hanger protrusion 57c is bent toward the high-speed hanger protrusion 56c, and a low-speed hanger bent portion 57d is formed.

  In a state where the high speed side and low speed side door panels 50 and 51 close the hall entrance 2, the inner peripheral end of the spiral spring 79 as a closing elastic body is fixed to the high speed hanger protrusion 56 c. And the edge part of the outer peripheral side of the spiral spring 79 is being fixed to the low speed side hanger bending part 57d. The spiral spring 79 expands and stores restoring force as the high-speed and low-speed door panels 50 and 51 are displaced from the fully closed position in the opening direction. The restoring force (spring force) of the spiral spring 79 acts on the high-speed door panel 50 in the fully opened state as a driving force in the closing direction. That is, when the high speed side door panel 50 is in the open state, the spiral spring 79 urges the high speed side door panel 50 in the closing direction.

  Further, the restoring force of the spiral spring 79 is also transmitted to the low speed side door panel 51 via the interlocking mechanism 64. Then, the high-speed and low-speed door panels 50 and 51 in the fully opened state are moved in the closing direction in conjunction with each other by the restoring force of the spiral spring 79. In the eighth embodiment, the extension 65a of the interlocking mechanism 64 in the fourth embodiment is arranged horizontally. Other configurations and operations are the same as those in the fourth embodiment.

  In the opening / closing device of the elevator hall door device as described above, the amount of extension of the spiral spring 79 is reduced to about half of the amount of extension of the spiral spring in Patent Document 1 when the door is opened, and the load applied to the spiral spring 79; Since the amount of operation of the spiral spring 79 is reduced, the durability of the spiral spring 79 can be improved, and the spiral spring 79 that satisfies the required life can be manufactured at a lower cost, which is less expensive than that of Patent Document 1. It can be set as a simple structure. At the same time, since the load applied to the spiral spring 79 and the amount of operation of the spiral spring 79 are reduced, the reliability with respect to the malfunction can be improved as compared with that of Patent Document 1. Further, by not using the inclined hanger rail as in Patent Document 2, the work efficiency at the time of assembly / disassembly can be improved.

Embodiment 9 FIG.
Next, a ninth embodiment of the present invention will be described. FIG. 21 is a plan view showing a part of the opening / closing device of the elevator hall door device according to the ninth embodiment. 22 is a rear view showing the high-speed side and low-speed side door hangers 56 and 57 of FIG. FIG. 23 is a plan view showing the high-speed side and low-speed side door hangers 56 and 57 of FIG. 21 with the door panel fully opened. 24 is a rear view showing the high-speed side and low-speed side door hangers 56 and 57 of FIG. 21 in a fully opened state of the door panel. 21 and 22 show the high-speed and low-speed door hangers 56 and 57 when the door panel is fully closed. 21 to 24, the structure below the high speed side and low speed side door hangers 56, 57 and the interlocking mechanism 64 are omitted.

  In the eighth embodiment, the low-speed hanger rail 53 is horizontal, but in the ninth embodiment, the low-speed hanger rail 53 is inclined downward from the open side of the low-speed side door panel 51 to the closed side. In the ninth embodiment, a low speed side panel leg mechanism 59 similar to that of the fourth embodiment is provided below the low speed side door panel 51. In the ninth embodiment, the gripping member 69 of the interlocking mechanism 64 in the fourth embodiment is slidable in the vertical direction with respect to the high speed side door hanger 56. Other configurations are the same as those in the fourth embodiment.

  In the opening / closing device of the elevator hall door device as described above, the opened high-speed door panel 50 moves in the closing direction by the restoring force of the spiral spring 79, and the opened low-speed door panel 51 moves in the closing direction by its own weight. The load applied to the spiral spring 79 can be reduced, and the life of the spiral spring 79 can be extended compared to the eighth embodiment. At the same time, the inclination angle of the low-speed side hanger rail 53 can be made smaller than the inclination angle of the low-speed side hanger rail 53 of the fourth embodiment, and the amount of vertical movement of the low-speed side door panel 51 can be reduced.

Embodiment 10 FIG.

The movable support slide rail 74 is slidable along a fixed support slide rail 75 fixed to the high speed door hanger 56. In the tenth embodiment, the extension 65a of the interlocking mechanism 64 in the fourth embodiment is arranged horizontally. Other configurations are the same as those of the ninth embodiment.

  Here, in the ninth embodiment, since the moving directions of the high speed side door hanger 56 and the low speed side door hanger 57 are shifted from each other, the spiral spring 79 extends in an oblique direction. However, the elevator hall door device as described above Since the relative moving directions of the high-speed door hanger 56 and the low-speed door hanger 57 coincide with each other, the extension direction of the spiral spring 79 can be made horizontal, and the influence of the inclination angle of the low-speed hanger rail 53 can be reduced. The tensile force of the spiral spring 79 can be set without receiving.

  In the fourth to tenth embodiments, the two high speed side door panels 50 and the low speed side door panel 51 are used. However, the present invention is not limited to this example. For example, a single door of a side open type door and a side open type One door panel or three or more door panels such as a three door door may be used.
