Description

  The present invention relates to an elevator apparatus in which a landing and a car door are opened and closed in a lateral direction, and more particularly, to an elevator apparatus in which a space between a landing-side sill (sill) for guiding the opening and closing of the door and a car-side sill is narrowed. .

  In general, a landing door opens and closes in conjunction with a car door driven by a drive mounted on the car, so that the landing door and the car door are engaged when the car is landed. In addition, an engagement device that protrudes toward the mating door is provided. The distance between the landing-side sill and the car-side sill has been increased so that the engaging device does not interfere with each sill during elevation. However, if the distance between the landing sill and the car sill increases, there is a risk that the wheel of a wheelchair or the like falls between the landing sill and the car sill or the infant's foot gets stuck.

  Therefore, in order to narrow the distance between the landing-side sill and the car-side sill as much as possible, for example, as disclosed in Japanese Patent Application Laid-Open No. 60-14884, a landing at a portion where the above-described engagement device is provided in vertical projection There is a technique for forming irregularities in the opposing portions of the side sill and the car side sill.

  The conventional technique for forming irregularities in the facing portion between the landing-side sill and the car-side sill has an advantage that the above problem can be solved because the distance between both sills is reduced. However, if the car is shaken due to an earthquake or the like because the distance between the two sills is narrow, there is a risk that both sills will collide with the uneven part and deform the sill. In addition, if the engagement device is operated while the car is moving up and down, there is a risk that the engagement device may interfere with the uneven portion. Therefore, no consideration was given to the new problem of having to replace the entire sill in these cases.

It is characterized by providing a protective member that is damaged and attenuates collision energy.

The present invention further includes a landing-side sill that guides the landing door in the lateral direction and a cage-side sill that moves and guides the cage door in the lateral direction, and the landing door and the cage sill are provided on one of the landing-side sill and the cage-side sill. In an elevator apparatus in which a concave portion that is spaced apart from a vertical projection of an engaging device that engages a door is formed, and a convex portion that is spaced from each other in the concave portion is formed in the other of the landing-side sill and the car-side sill. In addition, at least one of the concave portion or the convex portion that increases the chance of collision when the car is displaced due to shaking is formed by an auxiliary sill provided separately from the landing side sill and the car side sill. A protective member is provided only at the end of the door moving direction so as to be damaged when it collides with the auxiliary sill and attenuates the collision energy.

Also, a hall-side sill that guides the landing door laterally and a car-side sill that moves and guides the car door laterally are provided, and the hall door and the car door are connected to each other on one of the hall-side sill and the car-side sill. In an elevator apparatus in which a recessed portion that is separated from the vertical projection of the engaging device to be engaged is formed, and a convex portion that is separated from the vertical projection in the recessed portion is formed on the other of the landing-side sill and the car-side sill. A protective member that is broken when it collides with the engagement device is provided only at the end of at least one of the concave portion or the convex portion in the door movement direction where the chance of collision when the car is displaced is increased. To do.

Also, a hall-side sill that guides the landing door laterally and a car-side sill that moves and guides the car door laterally are provided, and the hall door and the car door are connected to each other on one of the hall-side sill and the car-side sill.

It is made of a material having a lower impact strength than the material of the landing-side sill and the car-side sill only at the end in the door movement direction of at least one of the concave portion or the convex portion that has a greater chance of collision when the car is displaced. A protective member is provided.

  According to the present invention, even if the car sways in the opening and closing direction of the door due to an earthquake or the like, both sills collide with each other in the uneven part, or even if the engaging device operates and interferes with the uneven part, the collision occurs. Is a protective member, and even if the protective member is damaged, it is only necessary to replace the protective member, so there is no need to replace the entire sill.

  Hereinafter, an embodiment of the present invention will be described with reference to FIGS. In general, an elevator apparatus includes a hoistway 2 provided perpendicularly to a building 1, a car 3 that is guided up and down in the hoistway 2, and a drive machine that drives the car 3 in the elevating direction (see FIG. (Not shown).

  The car 3 includes a car room 4 in which passengers are placed, a car-side door 5 that opens and closes the entrance of the car room 4, and a door rail 6 that suspends the car-side door 5 and guides movement in the lateral direction. And a car sill 7 having a groove 7G for engaging the lower end of the car-side door 5 and guiding it in the moving direction.

  On the other hand, the building 1 includes a boarding gate 9 that communicates each floor 8 and the hoistway 2, a boarding door 10 that opens and closes the boarding door 9 in the same direction as the car-side door 5, and the boarding door. 10 includes a door rail 11 that suspends 10 and guides opening and closing movement, and a landing sill 12 that has a groove 12G that engages the lower end of the landing-side door 10 and guides it in the moving direction.

  Further, the landing-side door 10 is opened and closed in conjunction with the opening and closing of the car-side door 5. The car-side door 5 is opened and closed by a door driving machine and a door driving mechanism (both not shown) mounted on the car 2.

  As for the linkage between the car-side door 5 and the landing-side door 10, an engagement device 13 that engages only in the door moving direction when the car 2 reaches the floor 8 is provided in both the doors 5 and 10. For example, as shown in FIG. 2, the engagement device 13 is an engagement provided on the car-side door 5 so that both U-shaped legs protrude toward the landing-side door 10 side. And an engagement roller 15 provided on the landing-side door 10 so as to protrude toward the car-side door 5 so as to face between both legs of the planar U-shaped engagement tool 14. In FIG. 2, two sets of engagement rollers 15 are provided.

  By the way, since the engaging roller 15 of the engaging device 13 protrudes to a position where it overlaps the car sill 7 in plan view, the car sill 7 moves to the engaging roller 15 of the landing-side door 10 when the car 2 is raised and lowered. It will collide. In order to avoid this, conventionally, the car sill 7 and the landing sill 12 face each other in parallel, and a clearance of 20 to 30 mm is secured. However, according to the present embodiment, the car sill 7 is formed with the concave groove 16 that allows the vertical projection of the engagement roller 15 to have a sufficient size, and the landing is made to fill the concave groove 16. The sill 12 is formed with a convex portion 17 having a size substantially commensurate with the vertical projection of the engaging roller 15 so that the gaps G0, G1, G2 between the car sill 7 and the landing sill 12 are approximately the same 6 to 10 mm. Can be.

  Since the gap between the car sill 7 and the landing sill 12 becomes narrower, when the car 2 is displaced due to shaking such as an earthquake, the chance of the bumps colliding increases, so the grooves 16 and the bumps Protective members 18 and 19 are provided on the projections and depressions 17 formed on the doors 7 and 12S in the moving direction of the door 5 or 10, respectively.

  Thus, by providing the protection members 18 and 19, for example, when the end of the groove 16 and the end of the convex portion 17 collide with each other as shown in FIG. Can be damaged, so that the collision energy can be attenuated at the time of the damage.

  Therefore, there is no damage to the car sill 7 or the landing sill 12, and it is only necessary to remove the protective member 19 or the protective members 18 and 19 and replace them with new ones. In addition, as long as this protection member is the structure provided in the at least one edge part of a recessed part or a convex part, other embodiment may be sufficient.

  In the above embodiment, the concave groove 16 is formed in the gill sill 7 and the convex portion 17 is formed in the landing sill 12, so that the process of forming them is added and the material yield is also poor.

  Therefore, in the embodiment shown in FIG. 5, the car sill 7A and the landing sill 12A are narrower than the car sill 7 and the landing sill 12 according to the above-described embodiment and have the same width over the entire length. The auxiliary car sill 7B and the auxiliary landing sill 12B are attached to the facing portions of the sill 12A and the landing sill 12A, respectively. In other words, two auxiliary car sills 7B are attached to the car sill 7A at an interval to form a groove 16 between the two auxiliary car sills 7B and the car sill 7A. The two auxiliary landing sills 12B are attached so as to face between the two auxiliary car sills 7B. The protective members 18 and 19 are attached to the auxiliary car sill 7B and the auxiliary landing sill 12B. In addition, as long as at least one of a recessed part or a convex part is a structure which forms with these auxiliary sills, other embodiment may be sufficient.

  Thus, by forming the concave groove 16 and the convex portion 17 by the auxiliary car sill 7B and the auxiliary landing sill 12B, each sill can be easily formed and the shape of each sill is simplified, so that the yield of the material is also increased. improves.

  By the way, the protective members 18, 19 may be made of the same material as the car sill 7 and the landing sill 12, and may be detachably attached to the concave groove 16 and the convex portion 17, but in order to easily absorb energy at the time of collision. In addition, it is easier to break than the car sill 7 and the landing sill 12. In other words, it is made of a material having a lower impact strength than the car sill 7 and the landing sill 12, for example, a synthetic resin such as polyamide resin or a low friction material. desirable.

  The protective members 18 and 19 may be attached by bonding or screwing, but may be attached as shown in FIGS. 6 and 7 show a hall sill 12 having a convex portion 17 as an example. In FIG. 6, a mounting pin 20 directed to the convex portion 17 is provided on the protective member 19, and the mounting pin 20 is inserted into a pin hole 21 provided in the convex portion 17 as indicated by an arrow for mounting. In FIG. 7, a mounting pin 22 facing the landing sill 12 is provided on the protection member 19, and the mounting pin 22 is inserted into a pin hole 23 provided in the landing sill 12 as indicated by an arrow and is mounted.

  Next, FIGS. 8 and 9 will be described. 5 shows the auxiliary car sill 7B and the auxiliary hall sill 12B in place of the auxiliary car sill 7B and the auxiliary hall sill 12B according to the embodiment shown in FIG. 5, but the auxiliary hall sill on the side of the hall sill 12A as an example. 12C will be described.

  The auxiliary landing sill 12C shown here is a protective member made of a synthetic resin such as a polyamide resin as a whole, and is formed in a U-shaped cross section. Then, the opening having a U-shaped cross-section is directed downward and is attached to the surface of the landing sill 12A facing the car sill via a fixture 12D. The fixture 12D is attached to the landing sill 12A by fastening means such as screws. Further, the fixture 12D has an engaging portion inserted into the opening of the auxiliary landing sill 12C, and the auxiliary landing sill 12C is sandwiched between the engaging portion and the landing sill 12A.

  In each of the above embodiments, when the car 2 is landed, the sill is prevented from being damaged when the car 2 swings in the door opening / closing direction. It swings in the orthogonal direction. When the car 2 sways and the gap between the car sill 7 and 7A and the hall sill 12 and 12A collides with each other, the collision part extends over substantially the entire length of the car sill 7 and 7A and the hall sill 12 and 12A. Since the collision force is dispersed without being concentrated, there is no damage that deforms the sill.

  However, if the car 2 swings in the direction perpendicular to the door opening / closing direction while the car 2 is moving up and down, as shown in FIG. 10, a fall extending downward from the bottom of each sill 7 and 12 By providing the prevention toe guards 24 and 25 with the inclined portions 24S and 25S inclined downward from the ends of the respective sills 7 and 12, damage to each sill can be prevented. That is, FIG. 10 shows a state in which the car sill 7 is positioned below the hall sill 12 and the space between both sills is narrowed due to the shaking of the car. When the car rises in this state, both sills collide, but before the collision of both sills, the tip of the car sill 7 comes into contact with the inclined portion 25S of the toe protection toe guard 25 on the landing side, Since the car is guided to the opposite side from the landing side, both sills do not collide directly. The inclined portion 25S is deformed by the tip of the car sill 7 coming into contact with the inclined portion 25S of the toe protection toe guard 25. This deformation can absorb the collision force and prevent deformation of both the sills 7 and 12. It is.

  On the other hand, when the car swings while the car is descending from the upper side of the landing sill 12 and the gap between the two sills 7 and 12 becomes narrow, the fall prevention apron 24 on the car sill 7 side The inclined portion 24S collides with the tip of the landing sill 12, guides the car to the side opposite to the landing side, and deforms to absorb the collision force.

  Therefore, the slopes 24S and 25S of the fall-preventing apron 24 and the toe protection toe guard 25 may be formed of a shape or material weaker in strength than the both sills 7 and 12.

  Still another embodiment in which a protective member is provided on a part of the auxiliary sill will be described with reference to FIGS. As shown in FIG. 11, the base 12F of the auxiliary landing sill 12E is formed of a resin such as acrylic, and the surface is covered with a design material 12H formed of stainless steel or aluminum as a material different from the base 12F. This is because the surface of the auxiliary landing sill 12E is made of the same material as the surface of the landing sill 12A, so that the design is not uncomfortable from the user's eyes as shown in FIG. The surface of the auxiliary landing sill 12E may be covered with anything as long as the design problem can be cleared without using the same material. In this embodiment, as shown in FIG. 12, an auxiliary sill is provided on the landing sill 12 side to form a convex shape, and on the car sill 7 side, the auxiliary sill is not provided and the car sill 7 itself is formed in a concave shape to move the door. A protective member 18 was attached to the end in the direction.

  Therefore, the configuration of the base 12F of the auxiliary landing sill 12E will be described in detail. As shown in FIG. 11, the auxiliary landing sill base 12 </ b> F is formed in an L shape, and one end thereof is detachably fixed to a side surface of the landing sill 12 </ b> A via a bolt 30. Further, the bent portion is supported by a rib 26 as shown in FIG. The ribs 26 are intermittently configured in the door opening / closing direction so as to reduce distortion due to sink marks during resin formation.

  Further, when a certain load, for example, a weight of 200 to 300 kilograms, is applied to the auxiliary landing sill 12E, the auxiliary landing sill 12E is configured to break due to a crack in the bent portion of the L shape. This is because the vehicle is not broken even when it is stepped on by a trolley or a person loaded with ordinary luggage, but it is broken when a strong force is applied such as when the engagement device 13 of the elevator collides. Then, it becomes possible to preferentially break the auxiliary landing sill base 12F and prevent damage to the sill. If necessary, as shown in FIG. 11, a notch 27 may be provided in advance in the auxiliary landing sill base 12 </ b> F, and the portion may be actively broken. Of course, the position where the notch 27 is provided is not limited to the position shown in FIG.

  Further, as shown in FIG. 14, since the auxiliary sill toe guard 28 and the sill toe guard 29 are composed of separate parts and are fixed separately, even if the auxiliary sill breaks, only the auxiliary sill toe guard 28 is discarded. At the same time, the sill toe guard 29 can be used as it is.

  In the present embodiment, the configuration in which the auxiliary landing sill 12E is provided on the landing sill side is described. However, as shown in FIG. 16, the auxiliary sill 7E (7F, 7H) is also added to the car sill 7A on the sill side. Two may be provided to form a concave configuration. Further, the landing sill side may be configured to be concave instead of convex.

  Furthermore, the structure which forms only a recessed part with an auxiliary | assistant sill may be sufficient.

  ADVANTAGE OF THE INVENTION According to this invention, even if the uneven | corrugated | grooved part formed in order to narrow a clearance gap between a car sill and a landing sill collides by the shaking of a car, etc., the elevator apparatus which can keep a damage to the minimum can be obtained. .
