Description

Specification

Elevator equipment technical field

The present invention relates to an elevator system in which a landing and a door of a car are opened and closed in a lateral direction, and in particular, a distance between a sill on a landing and a sill on a car that guides opening and closing of the door is reduced. Related to an elevator device. Background art

Generally, the landing door is opened and closed in conjunction with the car door, which is driven by a drive unit mounted on the car, so that the landing door engages with the car door when the car arrives on the floor. As described above, the engagement devices that protrude toward the mating doors are provided. In order to prevent this engaging device from interfering with each sill when ascending and descending, the distance between the landing sill and the car sill was increased. However, if the distance between the landing-side sill and the car-side sill is increased, there is a risk that wheels such as wheelchairs may fall between the landing-side sill and the car-side sill, or that infants' feet may get stuck.

In order to reduce 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. 60-148884, the above-mentioned engaging device is used in a vertical projection. There is a technology that forms unevenness in the area where the landing sill and car side sill are provided in the area where the sill is provided.

The conventional technique of forming irregularities on the opposing portions of the landing sill and the car sill has an advantage that the above problem can be solved because the interval between the sills is reduced. However, if the car shakes due to an earthquake or the like due to the narrow gap between the sills, there is a risk that the sills may collide with the uneven parts and deform the sills. Also take a ride If the engaging device is activated while the elevator is moving up and down, there is a danger that the engaging device will interfere with the irregularities. Therefore, the new problem of having to replace the entire sill in such a case was not considered. Disclosure of the invention

An object of the present invention is to provide an elevator apparatus that can minimize damage even if the uneven portions of the sill collide with each other or collide with an engagement device.

In order to achieve the above object, the present invention provides an engagement that engages the landing door and the car door with one of a landing side sill and a car side sill for guiding the landing door and the car door in a lateral direction, respectively. A recess is formed to be separated from the vertical projection of the device, and a projection is formed in the other of the landing side sill and the car side sill in the recess so that the vertical projections are separated from each other in the recess. The protection member was provided at the end in the door movement direction.

According to the above configuration, even if the car shakes due to an earthquake or the like and the two sills collide with each other at the uneven portion, or the engaging device operates and interferes with the uneven portion, the collision occurs with the protective member. Yes, 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. BRIEF DESCRIPTION OF THE FIGURES

Hereinafter, an embodiment of the present invention will be described with reference to FIGS. 1 to 4. In general, the elevator device is a hoistway 2 that is provided vertically to the building 1, a car 3 that is guided in the hoistway 2, and that drives the car 3 in the elevating direction. It consists of a drive machine (not shown).

The car 3 has a cab 4 for passengers and a cab 4 A car door 5 that opens and closes the entrance, a door rail 6 that suspends the car door 5 and guides the lateral movement, and a groove 7 that engages the lower end of the car door 5 and guides the car in the moving direction. And a cage sill 7 having a G. On the other hand, the building 1 has a landing 9 that connects each floor 8 with the hoistway 2. A landing door 10 that opens and closes the landing 9 in the same direction as the car door 5. A door rail 11 for suspending the door 10 and guiding the opening and closing movement; and a landing sill 12 having a groove 12G for engaging the lower end of the landing side door 10 and guiding in the moving direction. .

Further, the opening / closing of the landing-side door 10 is performed in conjunction with the opening / closing of the car-side door 5. The opening and closing of the car side door 5 is performed by a door driving device and a door driving mechanism (neither is shown) mounted on the car 2.

The linkage between the car-side door 5 and the landing-side door 10 is such that when the car 2 lands on the floor 8, an engagement device 13 that engages only in the door moving direction is provided on both doors 5, 10. ing. For example, as shown in FIG. 2, the engaging device 13 is attached to the car-side door 5 so that the U-shaped legs protrude toward the landing side door 10 side. An engaging device provided on the landing side door 10 so as to project toward the car side door 5 so as to reach between the legs of the flat U-shaped engaging device 14. It consists of a mouth and a mouth. 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 overlapping the car sill 7 in a plane, the car sill 7 engages with the landing side door 10 when the car 2 moves up and down. Roller 15 will collide. In order to avoid this, in the past, the car sill 7 and the landing sill 12 were made to face in parallel, and a gap of 20 to 30 mm was secured. However, according to the present embodiment, the cage sill 7 has an extra space for the vertical projection of the engagement roller 15. Form a concave groove 16 that allows a sufficient size, and fill the groove 16 with a landing sill 12 that has a projection approximately the size of the vertical projection of the engaging opening 15 The gap G between the car sill 7 and the landing sill 12 by forming part 17. , G ₁ , G ₂ , can be approximately 6 to: L 0 mm.

The gap between the car sill 7 and the landing sill 12 becomes narrower, and if the car 2 is displaced by shaking such as an earthquake, the chance of the above-mentioned uneven portion colliding becomes greater. Protective members 18 and 19 are provided at the concave portions formed by the convex portions 17 and especially at the ends 7S and 12S in the moving direction of the door 5 or 10 respectively.

By providing the protective members 18 and 19 in this way, for example, when the car 2 shakes, the end of the concave groove 16 and the end of the convex portion 17 collide as shown in FIG. However, since the protective member 19 can be positively damaged, 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 protection member 19 or the protection members 18 and 19 and replace it with a new one, which facilitates recovery after the earthquake. In addition, this protection member may be another embodiment as long as it is provided at least at one end of the concave portion or the convex portion.

In the above embodiment, since the groove 16 is formed in the sill 7 and the projection 17 is formed in the landing sill 12, the steps of forming them are added, and the yield of the material is poor.

Therefore, in the embodiment shown in FIG. 5, the car sill 7Α and the landing sill 12A, which are narrower in width 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 1 2B are attached to the opposite parts of the car sill 7A and the landing sill 12A, respectively. I tried to do it. In other words, two auxiliary car sills 7B are attached to the car sill 7A at intervals, so that a concave groove 16 is formed between the two auxiliary car sills 7B and the car sill 7A, and the landing One auxiliary landing sill 12B is attached to the sill 12A so as to face between the two auxiliary car sills 7B. The protection members 18 and 19 are attached to the auxiliary car sill 7B and the auxiliary landing sill 12B. Note that other embodiments may be used as long as at least one of the concave portion and the convex portion is formed by these auxiliary sills.

By forming the concave groove 16 and the convex portion 17 by the auxiliary cage sill 7 B and the auxiliary landing sill 1 2 B in this manner, the formation of each sill becomes easy. Since the shape of each sill is simplified, However, the yield of materials is also improved.

Incidentally, the protection members 18 and 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. In order to facilitate absorption, it is easier to break than the cage sill 7 and the landing sill 12; in other words, a material having a lower impact strength than the cage sill 7 and the landing sill 12 such as a synthetic resin such as polyamide resin. It is desirable to use a low friction material.

The protective members 18 and 19 may be attached by bonding or screwing, but may be attached as shown in FIGS. 6 and 7. 6 and 7 show a landing sill 12 provided with a projection 17 as an example. FIG. 6 shows that the protection member 19 is provided with a mounting pin 20 facing the projection 17, and the mounting pin 20 is inserted into a pin hole 21 provided in the projection 17 as shown by an arrow and mounted. Things. FIG. 7 shows that a protection pin 19 is provided with a mounting pin 22 facing the hall sill 12 and this mounting pin 22 is inserted into a pin hole 23 provided in the hall sill 12 as shown by an arrow. Attach what is there.

Next, FIGS. 8 and 9 will be described. This example relates to the auxiliary car sill and auxiliary sill that replaces the auxiliary car sill 7B and the auxiliary landing sill 12B according to the embodiment shown in Fig. 5, but the individual sills are examples of individual sills. The auxiliary landing sill 1 2 C on the 1 2 A side will be described.

The auxiliary landing sill 12C shown here is a protective member made of a synthetic resin such as polyamide resin, for example, and has a U-shaped cross section. Then, the hall sill 12A was mounted on the opposite surface of the hall sill 12A to the car sill via the fixture 12D with the U-shaped cross section facing downward. The fixture 12D is attached to the landing sill 12A by a fastening means such as a screw. Further, the fixing tool 12D has an engaging portion inserted into the opening of the auxiliary landing sill 12C. The auxiliary landing sill 12C is sandwiched between the engaging portion and the landing sill 12A. It is.

Each of the above embodiments is to prevent damage to each sill when the car 2 swings in the opening and closing direction of the door when the car 2 is on the floor. Also swings in a direction orthogonal to. When the car 2 swings and collides with the narrow gap between the car sills 7 and 7A and the landing sills 12 and 12A. The collision part is the car sills 7 and 7A and the landing sills 1 2 and 1 Since it covers almost the entire length of 2 A, the collision force is dispersed without being concentrated, so there is no damage to deform the sill.

However, when the car 2 swings in the direction perpendicular to the opening and closing direction of the door while the car 2 moves up and down, as shown in FIG. 10, the car 2 extends downward from the bottom of each sill 7, 12. The existing fall guards 24 and 25 are provided with slopes 24S and 25S, respectively, which are inclined downward from the ends of the sills 7 and 12 to prevent damage to the sills. Can be prevented. That is, FIG. The car sill 7 is located below the landing sill 12 and the gap between the sills is narrowed by the swing of the car. If the car rises in this state, the two sills will collide, but before the collision of the two sills, before the collision of the two sills, the tip of the car sill 7 is inclined to the landing side toe protection guard 25. The sills do not collide directly because the car is guided to the opposite side of the landing. When the tip of the basket sill 7 comes into contact with the inclined portion 25S of the toe protection guard 25, the inclined portion 25S is deformed. The deformation of 7, 12 can be prevented.

Conversely, if the car swings while the car is descending from above the landing sill 12 and the gap between the sills 7 and 12 becomes narrow, the fall prevention apron on the car sill 7 side will be used. The sloping portion 24 S of 24 collides with the tip of the landing sill 12, guiding the car to the opposite side of the landing side, and deforming to absorb the collision force.

Therefore, the slopes 24 S and 25 S of the fall prevention apron 24 and the toe protection toe guard 25 may be formed of a shape or material that is weaker in strength than the 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. 11 to 15. As shown in Fig. 11, the base 12 F of the auxiliary landing sill 12 E is made of resin such as acryl, and the surface is made of stainless steel or aluminum as a material different from the base 12 1 It is configured to be covered with 2H. 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 there is no unnaturalness in the design from the user's eyes as shown in Fig. 12. That's why. The auxiliary landing sill 12E may be covered with any material that can solve the design problem even if it is not the same material. In this embodiment, FIG. As described above, an auxiliary sill is provided on the landing sill 12 side to make it convex, and on the car sill 7 side, the cage sill 7 itself is formed in a concave shape without providing an auxiliary sill, and a protective member 18 is provided at the end in the door moving direction. Was attached.

Therefore, the structure 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 F is formed in an L shape, and one end is fixed to a side surface of the landing sill 12 A via a port 30 so as to be detachable. I have. Further, the bent portion is supported by a rib 26 as shown in FIG. The rib 26 is intermittently configured in the door opening and closing direction so as to reduce distortion due to sink during resin formation.

In addition, when a certain load is applied to the auxiliary landing sill 12E, for example, a weight of 200 to 300 kilograms, the L-shaped bent part is broken and cracked. Have been. This is because it does not break even when a trolley loaded with ordinary luggage or a person steps on it, but it breaks when a strong force is applied, such as when the engaging device 13 of Elevate hits. It is. Then, the auxiliary landing sill base 12 F can be preferentially broken to prevent damage to the sill. If necessary, as shown in Fig. 11, a notch 27 may be provided in advance on the auxiliary landing sill base 12F, and the portion may be positively broken at that portion. Of course, the position where the notch 27 is provided is not limited to the position shown in FIG.

Also, as shown in Fig. 14, the auxiliary silt guard 28 and the silt guard 29 are composed of separate parts and fixed separately, so that even if the auxiliary sill is broken, If only guard 28 is destroyed, silto guard 29 can be used as it is with sill. In this embodiment, the configuration in which the auxiliary landing sill 12E is provided on the landing sill side has been described. However, as shown in FIG. 16, the auxiliary sill 7A is also provided on the cage sill 7A on the car sill side. Two E (7 F, 7 H) may be provided to form a concave configuration. Further, the landing sill side may be formed in a concave shape instead of a convex shape. Further, a configuration in which only the concave portion is formed by the auxiliary sill may be employed. Industrial applicability

ADVANTAGE OF THE INVENTION According to this invention, even if the uneven | corrugated part formed in order to narrow a clearance gap between a car sill and a landing sill collides with the swing of a car, etc., the elevator apparatus which can minimize damage is obtained. be able to.
