Description

TECHNICAL FIELD The present invention relates to an elevator sill gap closing device for closing a sill gap generated between a sill of a car and a sill of a landing, and an elevator.

In general, an elevator is provided with a sill clearance when the car is stopped on the floor. This is to prevent the thresholds from coming into contact with each other when the car moves up and down. However, if there is a sill gap, there is a risk that an object may be dropped into the hoistway through the sill gap when a user gets in and out of the car. Therefore, a sill gap closing device has been proposed that includes a closing member that closes the sill gap.

The blocking body is an elongated member having a length corresponding to the width of the doorway of the car and a width corresponding to the size of the sill gap. The blocking body moves between an advanced position where it advances from the sill side of the car toward the sill of the landing when the car door is opened, and a retracted position where it retreats to the sill side of the car when the car door is closed. It is provided movably. The closing body closes the threshold gap in the advanced position, and opens the threshold gap in the retracted position.

As one form of closure, US Pat. The link mechanism can be switched between a first state and a second state, and is normally maintained in the first state by an elastic force such as a spring. When the car door is opened, a part of the car door (including a form in which the corresponding member or part is attached to the car door; hereinafter, "a part of the car door" is the same.) acts on the link mechanism, The linkage switches from the first state to the second state, thereby moving the closure to the extended position. On the other hand, when the car door is closed, the action of the part of the car door on the link mechanism is released, and the link mechanism returns to the first state by elastic force, thereby moving the closing body to the retracted position. In addition, the advancing position of the closing body is such that a part of the closing body (including a form in which the relevant member or part is attached to the closing body; hereinafter, the same applies when referred to as a "part of the closing body") contacts the stopper. defined by

Japanese Patent No. 6030209

By the way, in order for the threshold gap closing device to function properly, it is necessary to properly set the advance position of the closing member. In order to properly set the advanced position of the blocking body, it is necessary to adjust the spacing between the sill of the landing and the blocking body at the advanced position and the parallelism of the blocking body with respect to the sill of the landing. Alignment of the occlusion is critical. Ordinarily, when installing an elevator or reassembling a sill gap blocking device after disassembling it for maintenance, etc., the positioning of the blocker with respect to the sill of the landing is determined by the distance between the sill of the landing and the blocker at the advanced position. , adjusting the mounting position of the sill gap blocking device to the lower frame of the car, adjusting the position of a predetermined part in the sill gap blocking device, or adjusting the mounting position of the blocking body while checking the parallelism of the blocking body with respect to the threshold of the landing It is performed by performing various adjustment work such as adjustment. For this reason, alignment of the blockage with respect to the landing threshold is a very troublesome task.

Moreover, the sill of the landing includes an error in the mounting position in the depth direction for each floor. For this reason, usually, the alignment of the blockage with respect to the landing sill is based on the landing sill with the largest installation position error on the side closer to the car, and the distance between this landing sill and the blockage at the advanced position is By performing severe adjustment work so that the gap is just as close as possible so that it does not come into contact with the car, the gap between the sill of the landing and the blockage at the advanced position is minimized. There is a need to. This makes the alignment of the closure with respect to the landing threshold even more cumbersome.

Therefore, the present invention has been made in view of the above circumstances, and an object thereof is to provide an elevator sill gap closing device and an elevator that can easily, quickly and accurately align the closing body with respect to the sill of the landing. and

The elevator threshold gap closing device according to the present invention includes:

Hereinafter, as an embodiment of the elevator according to the present invention, an elevator equipped with a center open type (2CO) door device with one left and one right door will be described with reference to FIGS. 1 to 9. FIG.

As shown in FIG. 1 , elevator 1 includes hoistway 2 and car 3 . The hoistway 2 extends vertically in a multistory building. The car 3 ascends and descends in the hoistway 2 while being guided by the guide rails 20 and stops at a designated floor.

The car 3 includes a car door 30 , a door support structure 31 and a door opening/closing device 34 . The car door 30 moves laterally to open and close the front doorway of the car 3 to allow passengers to get on and off. The door support structure 31 is a structure that supports the car door 30 while allowing the car door 30 to be opened and closed. The door opening/closing device 34 is a device for opening and closing the car door 30 and is arranged, for example, in the upper front portion of the car 3 .

On the other hand, the landing 23 of each floor comprises a jamb 24 , a landing door 25 and a door support structure 26 . The three-way frame 24 is formed on the wall surface, and the inside of the frame serves as a doorway having a size corresponding to the doorway of the car 3 . A landing door 25 moves laterally to open and close a doorway in a jamb 24 to enable people to get on and off. The landing door 25 is normally closed, and is opened and closed following the opening and closing operation of the car door 30 of the car 3 stopped on the floor. The door support structure 26 is a structure that supports the landing door 25 while enabling the opening/closing operation of the landing door 25 .

As shown in FIG. 2 , the door support structure 31 of the car 3 includes door rails 32 and thresholds 33 . The door rail 32 is provided in the left-right direction on the front upper portion of the car 3 . The car door 30 is suspended from the door rail 32 so as to be slidable in the left-right direction along the door rail 32 . The threshold 33 is provided in the left-right direction along the lower edge of the doorway 3a of the car 3 so that both ends spread laterally beyond the lower edge of the doorway 3a. The threshold 33 is provided with a groove 330 . The groove 330 is formed along the left-right direction and receives the guide shoe 300 protruding downward from the lower end of the car door 30 . The door support structure 26 of the landing 23 also has a door rail and a threshold, and has the same structure as the door support structure 31 of the car 3 .

The car 3 is provided with a sill gap closing device 4 . The sill gap closing device 4 is a device for closing a gap (sill gap) generated between the sill 33 of the car 3 and the sill of the landing 23, and is provided in the lower front portion of the car 3 in the left-right direction. As can be understood from the description of the tip member to be described later, the term "blockage" does not only refer to a form in which the threshold gap is completely closed, but also a substantial "closure" in which a small gap is provided in units of millimeters. It is a concept that also includes

The threshold gap closing device 4 includes a closing body 40 . The closing member 40 is a long member having a length corresponding to the width of the doorway 3 a of the car 3 . As shown in FIGS. 3 and 4, the closure 40 has a width corresponding to the size of the threshold gap 28 . The closing member 40 is positioned at an advanced position ( FIG. 4 ) where it advances from the sill 33 side of the car 3 toward the sill 27 of the landing 23 when the car door 30 is opened, and when it is closed when the car door 30 is closed. It is provided movably between a retracted position (FIG. 3) retracted to the threshold 33 side. The closing body 40 closes the threshold gap 28 at the advanced position, and opens the threshold gap 28 at the retracted position.

The closing body 40 includes a closing portion 400 , a drooping portion 401 and a flange portion 402 . The blocking part 400 is a strip-shaped part elongated along the thresholds 33 and 27 . The closing part 400 moves forward and backward from below the threshold 33 to close and open the threshold gap 28 . The drooping part 401 is a strip-shaped part that hangs down from the tip edge of the blocking part 400 and extends along the thresholds 33 and 27 . The drooping part 401 faces (the end face of) the threshold 27 and constitutes the tip face of the closing body 40 . The flange portion 402 is a strip-shaped portion extending from the lower edge of the drooping portion 401 to the side facing the blocking portion 400 and extending along the thresholds 33 and 27 . That is, the closing member 40 is a member having an internal space with a U-shaped cross section.

As shown in FIGS. 5 to 7 (FIGS. 5 to 7 are views showing only the right side of the center CL of the doorway 3a of the car 3. Actually, the left side of the center CL is symmetrical and has the same configuration. ), and the closing member 40 is mounted on a linear motion mechanism 41 such as a linear guide, and moves linearly in parallel between the advanced position and the retracted position. The closing body 40 is normally urged in the retracting direction by the elastic force of an elastic body 42 such as a spring. The retracted position of the blocking body 40 is defined by a part of the blocking body 40 coming into contact with the stopper 43 .

The closure 40 is operatively connected with first and second cam mechanisms 44,45. The first cam mechanism 44 has a cam 46 and a cam follower 48 . The second cam mechanism 45 has a cam 47 and a cam follower 48 . Cams 46 and 47 are either part of car door 30 or part of closure 40 . Cam follower 48 is either part of car door 30 or part of closure 40 , or the other. In this embodiment cams 46 , 47 are attached to the lower portion of car door 30 and are part of car door 30 . Also in this embodiment, the cam follower 48 is a roller and is rotatably attached to the closure 40 and is part of the closure 40 .

When the car door 30 is opened, the first cam mechanism 44 urges the closing member 40 in the advancing direction along with the change in the relative positions of the cam 46 and the cam follower 48 of the first cam mechanism 44. The blocking body 40 moves to the advanced position, and the threshold gap 28 is blocked (Figs. 5->6->7).

On the other hand, when the car door 30 is closed, the closing member 40 is urged in the retracting direction by the second cam mechanism 45 as the relative positions of the cam 47 and the cam follower 48 of the second cam mechanism 45 change. As a result, the blocking member 40 moves to the retracted position, and the threshold gap 28 is opened (FIGS. 7→6→5). However, as described above, the closing member 40 is normally urged in the retreating direction by the elastic force of the elastic member 42 . Therefore, even without the second cam mechanism 45, when the car door 30 is closed, an elastic force is generated in the closing member 40 as the relative positions of the cam 46 and the cam follower 48 of the first cam mechanism 44 change. As a result, the closing member 40 is moved to the retracted position, and the threshold gap 28 is opened (FIGS. 7→6→5).

As shown in FIG. 8 , the threshold gap closing device 4 includes an alignment mechanism 49 . The positioning mechanism 49 is attached to the closing body 40 so that the tip thereof protrudes from the tip of the closing body 40 by a predetermined amount of protrusion, and the tip of the closing body 40 is brought into contact with the threshold 27 of the boarding point 23 . It is a mechanism that defines the advanced position, and is a mechanism for simply, quickly and accurately aligning the closing member 40 with the threshold 27 of the landing 23 . Note that the alignment means adjusting the distance between (the end surface of) the threshold 27 and the closing body 40 (the leading end surface (the drooping portion 401)) at the advanced position, or the closing body 40 (the end surface thereof) with respect to the threshold 27 (the end surface of the at least one of the parallelism adjustment of the tip surface (drooping portion 401)).

At least two positioning mechanisms 49 are provided at intervals in the longitudinal direction of the closing member 40 . In this embodiment, the alignment mechanisms 49 are provided at two locations on the left and right ends of the closing member 40 . A hole 401a is formed in a drooping portion 401 that constitutes the distal end surface of the closing body 40 of the portion of the closing body 40 where the alignment mechanism 49 is provided. The hole 401 a is a hole that penetrates the drooping portion 401 and communicates with the internal space of the closing member 40 . In this embodiment, the hole 401a is a circular hole. A long hole 402a is formed in the flange portion 402 of the portion of the closure 40 where the alignment mechanism 49 is provided. The long hole 402a is a hole penetrating through the flange portion 402 and elongated along the centerline direction of the hole 401a (that is, the moving direction of the closing member 40).

Alignment mechanism 49 includes tip member 490 . The tip member 490 is inserted through the hole 401 a of the closure 40 , and the tip of the tip member 490 protrudes from the drooping portion 401 of the closure 40 . In this embodiment, the tip member 490 has a columnar shape corresponding to the shape of the hole 401a of the closure 40 .

The tip member 490 is an elastic member such as rubber that can be elastically deformed. The elasticity is such that when the tip member 490 is pressed against the end surface of the threshold 27 of the landing 23, the tip of the tip member 490 is relatively easily compressed and deformed, and the amount of protrusion is reduced by several millimeters.

Alignment mechanism 49 includes a support member 492 . The support member 492 is a member that supports the distal end member 490 from the inner space side of the closing body 40 . More specifically, a metal shaft 491 is insert-molded to the tip member 490 , and the shaft 491 is coupled to the support member 492 , whereby the support member 492 supports the tip member 490 .

The support member 492 has a vertical piece 492a and a horizontal piece 492b. The vertical piece 492a is a piece that rises upward from the end of the horizontal piece 492b. A shaft 491 of the tip member 490 is coupled to the longitudinal piece 492a. A shaft 493 projects downward from the horizontal piece 492b. In this embodiment, the shaft 493 is a stud bolt screwed into a screw hole formed in the horizontal piece 492b. The shafts 493 are provided at two positions on the left and right sides of the horizontal piece 492b. Each shaft 493 is inserted into the long hole 402a of the flange portion 402 of the closure 40, and the support member 492 is fixed to the closure 40 by attaching a fastener 494 such as a nut. Then, in a state in which the fixation by the fixture 494 is released, the two shafts 493, 493 slide inside the long holes 402a, 402a, so that the support member 492 moves in the inner space of the closing body 40. 40 can be adjusted in the direction of the center line of the hole 401a. As a result, the amount of protrusion of the tip portion of the tip member 490 can be changed.

The configuration of the threshold gap closing device 4 according to the present embodiment is as described above. When the elevator is installed or when the threshold gap blocking device 4 is reassembled after being disassembled for maintenance or the like, the closing member 40 is aligned with the threshold 27 of the landing 23 as shown in FIGS. 9(a) and (b). 9(c) and (d) after setting the amount of protrusion of each tip of the tip members 490, 490 of the two alignment mechanisms 49, 49 to be the same predetermined amount of protrusion. As shown, the tip portions of the two tip members 490, 490 are brought into contact with the threshold 27 of the landing 23, and while maintaining this state, the appropriate configuration of the threshold gap closing device 4 is fixed in an appropriate state. It is done by

Therefore, according to the sill gap closing device 4 according to the present embodiment, the car can be opened while confirming the conventional gap between the sill of the landing and the blocking body at the advanced position and the parallelism of the blocking body with respect to the sill of the landing. Compared to the method of performing various adjustment work such as adjusting the mounting position of the threshold gap blocking device with respect to the lower frame of the platform, adjusting the position of predetermined parts in the threshold gap blocking device, or adjusting the mounting position of the closing body Alignment of the closure 40 with respect to the threshold 27 of 23 can be done simply, quickly and accurately.

The threshold 27 of the landing 23 includes mounting position errors in the depth direction for each floor. For this reason, the positional alignment of the closing member 40 with respect to the threshold 27 of the landing 23 is based on the threshold 27 of the landing 23 having the largest mounting position error on the side closer to the car 3, and the closing of the threshold 27 of the landing 23 and the advancing position is performed. The distance between the sill 27 of the landing 23 and the blocking body 40 at the advanced position is set to be the minimum distance that does not contact the body 40, and the installation position error is large on the side away from the car 3. Care must be taken to keep it small. According to the sill gap closing device 4 according to the present embodiment, the gap between the sill 27 of the landing 23 where the installation position error is largest on the side closer to the car 3 and the closing body 40 at the advanced position is the marginal gap that does not come into contact. This setting is achieved by at least one of setting the protrusion amount of the tip of the tip member 490 in the alignment mechanism 49 to be as small as possible, or using compressive deformation of the tip member 490 can do. As a result, according to the threshold gap closing device 4 according to the present embodiment, the closing member 40 can be aligned with the threshold 27 of the landing 23 more easily, quickly, and accurately.

Further, according to the threshold gap closing device 4 according to the present embodiment, the tip member 490, which is the contact portion of the landing 23 with the threshold 27, is an elastic member such as rubber that can be elastically deformed. Therefore, according to the sill gap closing device 4 according to the present embodiment, it is possible to suitably prevent noise from being generated due to contact with the sill 27 of the landing 23 when the closing body 40 moves to the advanced position. This is particularly effective when the aforementioned compression deformation of the tip member 490 is used to set the distance between the threshold 27 of the landing 23 and the closure 40 at the advanced position.

It should be noted that the present invention is not limited to the above embodiments, and various modifications can be made without departing from the gist of the present invention.

In the above embodiment, closure 40 is operatively connected to first and second cam mechanisms 44,45. This is the form described in Japanese Patent No. 6770722. However, the invention is not limited to this. The closure is not particularly limited to any form, including the form described in Patent Document 1 and the form described in Japanese Patent No. 6,403,023.

Incidentally, in the form described in Japanese Patent No. 6403023, the closure is operatively connected with the cam mechanism. The closing body is normally urged in the advancing direction by an elastic force such as a spring. A cam mechanism includes a cam and a cam follower. The cam is either part of the car door or part of the closure. The cam follower is either part of the car door or part of the closure. When the car door is opened, an elastic force is generated in the closing body as the relative positions of the cam and the cam follower change, thereby moving the closing body to the advanced position. On the other hand, when the car door is closed, the cam mechanism urges the closing body in the retracting direction as the relative positions of the cam and the cam follower change, thereby moving the closing body to the retracted position. The advanced position of the closing body is defined by a part of the closing body coming into contact with the stopper.

Alternatively, conversely, the closing body is normally urged in the retracting direction by the elastic force of a spring or the like, and when the car door is opened, the closing body is closed as the relative positions of the cam and the cam follower change. When the body is urged in the advance direction by the cam mechanism, the closing body moves to the advanced position and the car door closes, elastic force is exerted on the closing body as the relative positions of the cam and the cam follower change. may be developed to move the blocking body to the retracted position.

Further, in the above-described embodiment, the tip of the alignment mechanism 49 has elasticity capable of elastic deformation. However, the invention is not limited to this. For example, the tip may be a rigid body as long as the problem of noise generation does not occur.

In the above-described embodiment, the threshold gap closing device 4 is applied to a center open type (2CO) door device with one door on each side. However, the invention is not limited to this. The threshold gap blockage device includes a side-open type (2S) door device with two doors, a center-open type (4CO) door device with two left and right doors, and a side-open type (1S) door device with one door. It goes without saying that the present invention can be applied to various door devices such as a door device.
