    First, the overall configuration of the elevator apparatus will be described with reference to FIG. As shown in FIG. 1, the elevator apparatus 1 includes a passenger car 4 and a counterweight 5 disposed in a hoistway 3. Above the hoistway 3 is provided a machine room 6 in which a hoisting machine 7 for driving a main rope 9 and a control device 8 are installed. The control device 8 controls the entire elevator device 1 and controls the hoisting machine 7 in accordance with a landing call or a car call so that the car 4 is landed on the floor where the call was made.

    A so-called machine room-less elevator device in which the hoisting machine 7 and the control device 8 are downsized and provided in the upper part in the hoistway 3 without providing the machine room 6 may be used.

    In this elevator apparatus 1, an entrance 12 that leads to a car 4 in the hoistway 3 is provided at a landing 11 provided on each floor of the building, and a landing door 2 is provided at the entrance 12. The landing door 2 is engaged with the side of the car door 25 provided at the entrance / exit 24 of the car 4 via an interlock mechanism (not shown) when the car 4 is landed, and interlocks with the opening and closing of the car door 25. Opens and closes.

FIG. 2 is a perspective view of the car door 25 provided at the entrance / exit of the car 4 in the door closed end position (fully closed position) as seen from the landing 11 side. The car door 25 is a so-called double-opening method in which two door panels 25a and 25b (the door surface plate is not shown) are opened to the left and right in different directions. These two doors panels 25a, 25b are driven more illustrated lateral direction door opener structure, and is opened and closed.

Incidentally, the door opening and closing Organization are well known and does not relate directly to the present invention is the structure description is omitted, the power of the motor (not shown), two doors panels 25a, 25b and in conjunction with each other, It is driven in the left-right direction along the guide rail to open and close.

A car-side sill 31 is provided at the entrance / exit part of the car 4, and the two door panels 25a and 25b constituting the car door 25 described above are slidably guided along the opening and closing direction thereof. . This car-side sill 31 is provided at the lower side of the entrance / exit 24 of the car, and the guide grooves formed on the upper surface thereof engage with the lower ends of the two door panels 25a and 25b, respectively. Is guided in the opening and closing direction.

    A sill 32 is provided on the platform 11 side as shown in FIG. The platform-side sill 32 is disposed opposite to one side surface (left side surface in FIG. 3) of the car-side sill 31 with a predetermined distance. A guide groove is also formed on the upper surface of the threshold 32 on the landing side, and guides the landing door 2 shown in FIG. 1 so as to be slidable along the opening and closing direction.

    The landing-side door 2 is also of a double-opening type having two door panels (not shown). As described above, when the car 4 reaches the landing 11, it engages with the car door 25 and the car door. 25 opens and closes together. That is, the landing door 2 has two door panels locked in a closed state by an interlock mechanism (not shown) when the car 4 is not landing, and when the car 4 is landing, the car 4 The locking state described above is released by engaging with an engaging member (not shown) on the side, and the door is opened and closed together with the car door 25.

When the car 4 is landed to a predetermined floor, as described above, between the Ri field side of the threshold 32 that multiply the threshold 31 of the car side, resulting a gap shown in Figure 3. In the embodiment of the present invention, a closing member 35 is provided to close the gap as shown in the figure.

As shown in FIG. 2, the closing member 35 is divided into left and right. This divided part is a part where the car-side sill 31 passes over an interlock mechanism (specifically, a roller part engaged with the car side) provided on the landing side when the car 4 is raised and lowered, In order to allow passage of the interlock mechanism, it is divided with a space left and right. In other words, event, even if the lift is car while being fed to a position closing the closing member, the interlocking mechanism of the ride Ri field side, passes through the formed divided portion of the closing member 35 fed out space since, never closing member paid out and the interlock mechanism will collide.

The ride Ri field side of the threshold 32, at the opposite state of the threshold 31 of the car side, block (not shown) loosely fitted and projects the divided space portions is provided. This block, multiplication Ri field side of the sill 32, opposed to the sill 31 of the car side and is integrally provided at the portion facing the divided spatial portion of the blocking member 35. Therefore, the car 4 is landed, ride Ri when the threshold 32 and the car side of the sill 31 of the field side faces protrudes ride Ri field side of the sill 32 in a space portion provided block is divided into Will be loosely fitted. For this reason, the space generated in the divided portion is substantially blocked by the block that is loosely fitted in the divided portion, and it is possible to prevent small items from falling from the space of the divided portion.

The upper surface of the closing member 35, as shown in Figure 3, is positioned below the upper surface of the sill 32 of the car side of the sill 31 and ride Ri field side at the closing position closes the gap. Moreover, the planar shape is formed in the shape dimension which can block | close the clearance gap between the thresholds 31 and 32. FIG. That is, it has a planar shape having a length that is slightly larger than the entrance of the cage and a width that is slightly larger than the gap between the sills 31 and 32.

    Further, the chamfer is applied to the upper corner of the closing member 35.

    The closing member 35 may be made of metal or resin, but a resin material may be used in consideration of workability, buffering properties with other parts, and the like.

    The closing member 35 is configured to be movable between a closing position where the gap between the sills 31 and 32 shown in FIG. 3 is closed and a retreat position where the sill 31 is retracted below the sill 31 on the car side as shown in FIG. Has been. That is, it is driven in the vertical and horizontal directions in FIG.

The closing member 35 is mounted on a bracket 37 arranged in a vertical direction via an elastic body 38 such as a leaf spring (hereinafter, described as a leaf spring 38) . Therefore closing member 35 is more plate wave Ne is swinging rotatably supported to the spacing direction of the car side of the sill 31 and ride Ri field side of the threshold 32. The leaf spring 38 is also divided at the same portion as the closing member 35 as shown in FIG. 2, and supports the divided corresponding portions of the closing member 35 together with the bracket 37.

    As shown in FIG. 2, the drive mechanism includes a push-down member 40, a first link mechanism 50, and a second link mechanism 60.

Depressing member 40, closing is disposed below the member 35 engages the lower end of the bracket 37 lowers the bracket 37 of the always-on this, the closing member 35, as shown in Figure 2, the cage-side sill 31 is positioned at a retracted position below 31. That is, as shown in FIG. 4, the push-down member 40 has a concave portion 41 that is notched in a U shape at a portion corresponding to the lower end side surface of the bracket 37. An engaging body 42 is integrally attached to the upper side of the recess 41 in the figure.

    An engagement pin 371 that is integrally attached to the side surface of the lower end portion of the bracket 37 is inserted into the recess 41. The push-down member 40 is constantly receiving a downward force due to its own weight. When the push-down member 40 is lowered, the engagement pin 371 inserted into the recess 41 is pushed down by engaging with the engagement body 42, and is provided on the bracket 37 and the upper portion thereof via the leaf spring 38. The closing member 35 is pushed down.

    With the opening operation of the car door 25 shown in FIG. 2, the first link mechanism 50 has a car door at a preset open position near the door open end of the car door 25 (the position at which the car door 25 is fully opened). The push-down member 40 is raised by engaging with the side actuating member 70 and receiving a moving force of the car door 25 in the door opening direction.

    The first link mechanism 50 includes an operation link 51 and a parallel link 52 as shown in FIG.

    The working link 51 is pivotally supported by the car-side support member 53 at the intermediate portion in the longitudinal direction of the character-shaped portion 511 by a support shaft. In addition, an engaging portion 512 with the actuating member 70 on the side of the car door 25 is integrally formed at the upper portion of the figure-shaped portion 511 as shown in FIG. Furthermore, the lower end of the figure-shaped portion 511 shown in the figure is pivotally connected to the upper part of a support member 401 that is integrally provided upright on the left end of the push-down member 40 through the support shaft. Yes.

    Both ends of the parallel link 52 are rotatably connected to the lower portions of the support members 53 and 401 described above via support shafts. A parallel link 52 is also provided at the right end of the push-down member 40 with the car-side support member 53.

    Therefore, in the first link mechanism 50, the inclined engaging portion 512 of the operating link 51 is engaged with the operating member 70 provided on the door panel 25a side with the opening operation of the car door 25, and the door opening is performed. It receives a force in the direction (left side in the figure) and rotates counterclockwise in the figure. By this rotation, the push-down member 40 is translated upward together with the parallel link 52.

    As shown in FIGS. 3 and 4, the second link mechanism 60 is configured between the bracket 37 and the support member 63 on the car side, and moves sideways while raising the bracket 37 as the push-down member 40 rises. Let That is, the second link mechanism 60 includes two parallel links 61 and 62, and both ends of the second link mechanism 60 are rotatably connected to the bracket 37 and the car-side support member 63 via the support shaft. In addition, a torsion spring 65 is provided on the support shaft on the support member 63 side of the parallel links 61 and 62, and the clockwise rotation shown in the drawing is applied to the parallel links 61 and 62. Therefore, the bracket 37 always receives an upward spring force by the torsion spring 65.

    When the parallel links 61 and 62 are rotated clockwise from the state shown in FIG. 4 in the second link mechanism 60, the bracket 37 is extended to the left in the drawing and moved upward in the drawing to move the state shown in FIG. Displace to For this reason, the closing member 35 attached on the bracket 37 via the leaf spring 38 moves from the retracted position below the car side sill 31 shown in FIG. 2 to the closing position shown obliquely above in FIG.

    In the above configuration, when the car door 25 is in the closed door closed position, the operation member 70 on the car door 25 side is engaged with the operation link 51 of the first link mechanism 50 as shown in FIG. The first link mechanism 50 does not receive the acting force from the car door 25 side. For this reason, the push-down member 40 is lowered by its own weight, and the engagement pin 371 on the bracket 37 side inserted into the recess 41 is pushed down by engagement with the engagement body 42 as shown in FIG. It has been. Therefore, the bracket 37 and the closing member 35 provided on the upper portion of the bracket 37 via the leaf spring 38 are in a retracted position below the car-side sill 31.

    When the car 4 reaches the landing, the car door 25 opens, and the door panel 25a reaches the preset open position near the door open end (the fully open position of the car door 25). The operating member 70 engages with the inclined engaging portion 512 of the operating link 51 constituting the first link mechanism 50. For this reason, the operation link 51 receives a moving force in the door opening direction (leftward in the figure) of the door panel 25a and rotates counterclockwise in the figure. The actuating link 51 and the parallel link 52 raise the push-down member 40 by this counterclockwise rotation.

    As the push-down member 40 is lifted, the push-down force by the engagement body 42 shown in FIG. 4 is eliminated, and the bracket 37 engaged with the engagement body 42 via the engagement pin 371 is caused by the spring force of the torsion spring 65. To rise. Since the bracket 37 is attached to the support member 63 on the car side by the parallel links 61 and 62, the bracket 37 moves upward while moving to the left in the drawing. For this reason, the closing member 35 attached on the bracket 37 via the leaf spring 38 moves from the retracted position below the car side sill 31 shown in FIG. 2 to the closing position shown obliquely above in FIG.

The operation to the closing position stops when the first link mechanism 50 rotates by a predetermined rotation angle counterclockwise. That is, the first link mechanism 50 engaging portion 512 which is inclined in the actuation links 5 1 constituting the a predetermined rotation angle as described above, when rotated, is set the inclination angle such that the horizontal state. For this reason, even if the door opening operation continues until the door panel 25a reaches the door open end (fully open state), the first link mechanism 50 does not rotate any more, and the closing member 35 maintains the closing position shown in FIG. To do.

    At this closing position, the closing member 35 closes the gap between the sills 31 and 32, so that small items do not fall into the pit from this gap and can be easily collected. Moreover, since the upper surface of the closing member 35 is located below the upper surfaces of the sills 31 and 32, the load of the object located on the sills 31 and 32 is not applied to the closing member 35, and the load is applied. Damage to the support portion of the closing member 35 can be prevented.

    When the load on the car 4 changes greatly in the state where the gap is closed by the closing member 35, the car 4 may temporarily rise slightly. Even if such a temporary rise of the car 4 occurs, the upper corner portion of the closing member 35 is chamfered and the closing member 35 is supported by the leaf spring 38. Does not occur.

    For example, when a passenger who is in a full state in the car 4 gets down at a time, the car rises temporarily, though only slightly. At this time, the closing member 35 at the closing position shown in FIG. 3 may also rise and come into contact with the lower side portions of the thresholds 31 and 32. However, since the chamfer is applied to the upper corner portion of the closing member 35 facing the lower side portion of the sill 32 on the landing side, the contact force of this portion is weakened, and damage due to contact can be prevented. Further, since the closing member 35 is supported by the leaf spring 38, the leaf spring 38 is also bent in the vertical direction at the time of contact described above. Can prevent damage due to contact.

    On the other hand, when the car door 25 is closed and moved to a predetermined door closing position, the operating member 70 provided on the door panel 25a side is moved from the engaging portion 512 of the operating link 51 constituting the first link mechanism 50. Leave. For this reason, the force applied to the first link mechanism 50 from the operating member 70 is released, and the push-down member 40 is lowered by its own weight. Therefore, the second link mechanism 60 rotates counterclockwise from the state shown in FIG. 3, and the closing member 35 attached on the bracket 37 and the plate spring 38 via the leaf spring 38 is illustrated from the closing position shown in FIG. It is moved to the lower right and returned to the retracted position below the car side sill 31.

    Here, even if the gap between the sills 31 and 32 varies, the closing member 35 is attached to the bracket 37 via the leaf spring 38 and can be moved back and forth in the moving direction. It is possible to reliably close the gap without generating any.

In addition, when the leaf | plate spring 38 bends, a clearance gap may arise in the junction part with the bracket 37, and when dust etc. are pinched | interposed into this clearance gap, it will be considered that it cannot return to an original shape. Therefore, it is advisable to provide guards such as caulking and gabber installation in advance for the portion where this gap may occur.

    In the above-described embodiment, the first link mechanism 50 is engaged with the operation member 70 on the car door side when the car door 25 reaches the door open end (fully open), and the closing member 35 is moved to the closing position. It was moved. In this configuration, the closing member does not enter the closed state unless the car is opened to the vicinity of the door opening end. However, in the embodiment shown in FIG. 5, the closing member is moved to the closing position at an earlier stage.

    In this embodiment, the first link mechanism 50 engages the operating link 51 with the operating member 70 on the car door 25 side at an open position set in advance near the door closed end (fully closed position) of the car door 25. The push-down member 40 is raised by the moving force of the car door 25 in the opening direction. Further, the actuating member 70 on the car door 25 side is supported so as to be slidable relative to the car door 25 along the opening / closing direction (the left-right direction in the drawing). When a spring force is normally applied in the direction of engagement with the operation link 51 and an engagement reaction force is received by the engagement with the operation link 51, the spring link is opposed to the above-described spring force and is relative to the car door 25 side. It was configured to slide.

Specifically, the engaging portion 512A of the operating link 51 constituting the first link mechanism 50 is inclined from the upper end of the square-shaped portion 511 as shown in the drawing to the right in the drawing, contrary to the above-described embodiment. Formed. The actuating member 70 on the side of the car door 25 is attached to the left end of the horizontally long moving bracket 71 in the figure, and the car door 25 is engaged with the long hole 711 formed in the moving bracket 71 and the support pin 251 on the car door 25 side. It was supported so that it could slide along 25 open / close directions. Further, the spring 72 between the movable bracket 71 and the car door 25 is provided, to always-on operation moving member 70, giving a spring force of the engaging direction to (leftward) with the working link 51 . The actuating member 70 engages with the actuating link 51, and when the actuating member 70 receives an engaging reaction force after rotating the actuating link 51 by a predetermined rotation angle, the actuating member 70 is relatively opposed to the door 25 side against the spring force of the spring 72. It was configured to slide.

    In the above configuration, when the car door 25 is at the door closed end (fully closed position), the operation member 70 on the car door 25 side is not related to the operation link 51 of the first link mechanism 50 as shown in FIG. The first link mechanism 50 does not receive the acting force from the car door 25 side. For this reason, the push-down member 40 is lowered by its own weight, and the engagement pin 371 on the bracket 37 side inserted into the recess 41 is pushed down by engagement with the engagement body 42 as shown in FIG. The closing member 35 provided on the bracket 37 and the upper portion thereof via the leaf spring 38 is in a retracted position below the car-side sill 31.

When the car 4 reaches the landing and the car door 25 opens and reaches a preset open position near the door closed end (fully closed position) of the car door 25, as shown in FIG. The operating member 70 provided on the panel 25a side comes into contact with and engages with the engaging portion 512A of the operating link 51 constituting the first link mechanism 50. This abutting engagement position is an opening position at an earlier stage from the start of the door opening than the opening position set in advance near the door opening end (fully opened position) in the above-described embodiment.

    Due to this abutting engagement, the actuation link 51 receives a moving force in the door opening direction (leftward in the figure) of the car door 25 and is located at the intermediate portion of the character-shaped portion 511 as in the above-described embodiment. It rotates counterclockwise in the figure around the provided support shaft. The actuating link 51 and the parallel link 52 raise the push-down member 40 by this counterclockwise rotation. As the push-down member 40 moves up, the closing member 35 moves from the retracted position below the car-side sill 31 to the closing position shown in FIG.

    The operation link 51 stops the counterclockwise rotation by the operation to the closing position, and the operation member 70 on the car door 25 side receives the engagement reaction force and stops. At this time, the car door 25 is in the process of moving to the door open end and continues to move to the left in the figure. Therefore, the actuating member 70 supported by the moving bracket 71 slides relative to the car door 25 against the spring force of the spring 72 and allows the car door 25 to move to the left in the drawing.

    That is, since the first link mechanism 50 is activated at an early time from the start of the door opening of the car door 25 and moves the closing member 35 to the closing position, the passenger enters and leaves the small items while the car door 25 is being opened. Even if dropped, small items do not fall from the gap to the pit and can be easily collected.

On the other hand, when the car door 25 is closed, since the spring 72 is stored for a while after the start of the door closing, only the car door 25 moves and the operating member on the moving bracket 71 remains stopped. When the car door 25 moves to a predetermined door closing position, the support pin 251 on the car door 25 side moves to the right end side in the figure of the long hole 711, and the moving bracket 71 and the actuating member 70 are shown in the right side through the long hole 711. Move towards. For this reason, the operating member 70 is separated from the engaging portion 512 </ b> A of the operating link 51 constituting the first link mechanism 50. Thus, the force applied to the first link mechanism 50 from the operating member 70 is released, and the push-down member 40 is lowered by its own weight. Therefore, the closing member attached to the bracket 37 and the leaf spring 38 thereon. 35 is moved obliquely downward to the right from the closing position shown in FIG. 3 and returned to the retracted position below the car side sill 31.

    That is, since the hysteresis characteristic is provided between the opening / closing operation of the car door 25 and the closing operation of the closing member 35, the closing member 35 can be closed at the optimal opening position of the car door 25.

In the above embodiment, the upper surface of the closing member 35, as shown in Figure 3, had is positioned below the upper surface of the car side and ride Ri situ side sill 31 and 32 at the closing position, this application invention is not limited to this, the upper surface of the closing member 35 may be substantially are positioned at the same height as the upper surface of the car side and ride Ri field side of the sill 31 and 32 at the closing position. That is, the width of the closing member 35 is set so as to enter the gap between the sills 31 and 32, and the upward stroke of the closing member 35 is set so that the upper surface of the closing member 35 is substantially the same height as the upper surfaces of the sills 31 and 32. What is necessary is just to set. In this case, the leaf spring 38 that supports the closing member 35 is one that has a high rigidity in the vertical direction.

    If comprised in this way, the flat doorway without a clearance gap between the sills 31 and 32 can be formed.

    Although several embodiments of the present invention have been described, these embodiments have been presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
