BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 to FIG. 7 show a first embodiment, and FIG. 1 is a front view of the door device provided at the entrance / exit of the elevator hall as seen from the hoistway side. A doorway 2 is formed on the inner wall la of the hoistway 1. On the inner wall la of the hoistway 1, a hanger case 5 is attached horizontally via a pair of brackets 6 on the upper side of the entrance 2.

[0017] As shown in Figs. 2 to 4, the hanger case 5 has an L-shaped cross section having a horizontal plate 5a and a vertical plate 5b, and each bracket 6 has an L-shaped cross section having a horizontal plate 6a and a vertical plate 6b. The vertical plate 6 b is fixed to the inner wall la of the hoistway 1. The pair of brackets 6 are attached to the inner wall surface 1a side by side at a predetermined interval from left to right. The horizontal plate 6a of each bracket 6 is formed with a pair of elongated holes 9 extending in the front-rear direction. Further, the horizontal plate 6a of the hanger case 5 is formed with a long hole 10 extending to the left and right so as to be orthogonal to the long hole 9 of the bracket 6 at a portion corresponding to the horizontal plate 6a of each bracket 6. .

[0018] The horizontal plate 5a of the hanger case 5 crosses the long holes 9 and 10 and is abutted against the lower surface of the horizontal plate 6a of each bracket 6, and further, the lower surface of the horizontal plate 5a of the hanger case 5 A water shielding plate 12 is provided corresponding to the intersection with the long holes 9 and 10.

[0019] These water shielding plates 12 are longer than the width of the bracket 6 and the long hole 10 of the hanger case 5. The strip has a length, and a pair of circular through holes 12a are formed on the plate surface as shown in FIG. The pair of through holes 12 a of the water shielding plate 12 is formed at the same pitch as the pair of long holes 9 formed in parallel with the horizontal plate 6 a of the bracket 6. As the material of the water shielding plate 12, a metal such as iron, a hard synthetic resin, or a rubber-like soft synthetic resin is used.

[0020] Then, a bolt 14 is inserted from the upper surface side of the horizontal plate 6a of the bracket 6 to the intersecting portion of the long holes 9 and 10 and the through hole 12a of the water shielding plate 12, and a nut is inserted at the end of the insertion side. 15 is screwed, and the hanger case 5 is fastened and fixed to the bracket 6 by tightening these bolts 14 and nuts 15.

The hanger case 5 is moved to a predetermined position by moving the hanger case 5 back and forth along the long hole 9 and moving left and right along the long hole 10 before tightening with the bolt 14. Can be positioned. The circular through hole 12a formed in the water shielding plate 12 has an inner diameter that is slightly larger than the outer diameter of the bolt 14, and smaller than the outer diameter of the head of the bolt 14 and the outer diameter of the nut 15. It has become.

A hanger rail 18 is horizontally installed inside the hanger case 5, and a pair of door hangers 19 are suspended on the hanger rail 18 via a plurality of rollers 21, respectively. The door panels 20 are attached to the door hangers 19, and the door panels 20 move to the left and right along the hanger rail 18 together with the door hangers 19, thereby opening and closing the entrance 2.

[0023] The door hanger 19 is provided with a lock mechanism 22 that locks the door panels 20 when the door panels 20 are closed, an electrical contact mechanism 23 that detects the achievement of the lock, and the like.

In the present embodiment, as shown in FIG. 6, a rectangular opening is formed at a portion where the long hole 9 of the bracket 6 and the long hole 10 of the hanger case 5 intersect, and bolts 14 are formed in the rectangular opening. Therefore, a space S indicated by hatching in FIG. 6 remains at the corner of the opening. However, the water shielding plate 12 is provided on the lower surface of the horizontal plate 5 a of the hanger case 5, so that the space S is covered with the water shielding plate 12.

Accordingly, liquid such as rain water or cleaning water drips on the horizontal plate 6a of the bracket 6. Even if the liquid drops, the inconvenience that the liquid flows into the lower side of the horizontal plate 5a of the hanger case 5 through the space S is prevented.

[0026] To explain further, the space S is covered to some extent by the head 14a of the bolt 14. The head 14a of the bolt 14 has an outer diameter that is so large that the horizontal plate of the head 14a and the bracket 6 The liquid soaks into the space 6a, and the liquid reaches the space S. In this embodiment, a water shielding plate 12 having a large area capable of sufficiently covering the entire long hole 10 is provided on the lower surface side of the horizontal plate 5a of the hanger case 5, and therefore the bracket 6 Upper force of horizontal plate 6a Even if liquid enters the space S, the liquid is not blocked by the water shielding plate 12, and does not flow into the lower side of the horizontal plate 5a of the hanger case 5.

FIG. 5 is a view of the water shielding plate 12 as viewed from below, and the inner diameter of the through hole 12a for passing the bolt 14 formed in the water shielding plate 12 is screwed to the bolt 14. Therefore, the gap between the outer periphery of the bolt 14 and the inner periphery of the through hole 12 a is sealed by the nut 15. Therefore, even if the liquid penetrates into the space S and flows into the gap between the outer periphery of the bolt 14 and the inner periphery of the through hole 12a, the liquid is below the impermeable plate 12. There is no such thing as spilling to the side.

[0028] In this way, the flow of liquid to the lower side of the horizontal plate 5a of the hanger case 5 can be reliably suppressed, and therefore the electrical contact mechanism 23 and the lock mechanism 22 on the lower side of the horizontal plate 5a of the hanger case 5 are prevented. The influence of the liquid can be eliminated to prevent malfunction of the electrical contact mechanism 23 and malfunction of the lock mechanism 22.

[0029] FIG. 7 shows that the hanger case 5 is positioned so as to be greatly displaced to the right with respect to the bracket 6, and one end of the long hole 10 of the hanger case 5 projects outward from one side edge of the bracket 6. The case of the state to be shown is shown. In this case, when one end of the long hole 10 is exposed to the outside, and thus liquid drops on the horizontal plate 5a of the hanger case 5, the liquid flows into the exposed portion of the long hole 10. To do.

However, the water shielding plate 12 is attached to the lower surface side of the hanger case 5, and the water shielding plate 12 has a length sufficiently longer than the long hole 10. Sealed by the water shielding plate 12 including the exposed part, and the exposed part of the long hole 10 Even if the body flows in, the liquid does not flow into the lower side of the horizontal plate 5a of the hanger case 5.

Accordingly, even in this case, the influence of the liquid on the electrical contact mechanism 23 and the lock mechanism 22 on the lower side of the horizontal plate 5a of the hanger case 5 is eliminated, and the malfunction of the electrical contact mechanism 23 and the operation of the lock mechanism 22 are performed. Defects can be prevented.

FIG. 8 shows a water shielding plate 12 according to the second embodiment. In this water shielding plate 12, the nut 15 in the first embodiment is a lower surface of the water shielding plate 12. The nut 14 is integrally attached by welding or the like, and a screwing portion in which the bolt 14 can be screwed is constituted by the nut 15.

Therefore, in the case of the present embodiment, when fastening the hanger case 5 and the water shielding plate 12 to the bracket 6 with the bolts 14, the bolts 14 that do not require handling of the nut 15 as a single item are removed from the water shielding plate 12. The water shielding plate 12 can be efficiently attached to the horizontal plate 5a of the hanger case 5 by a series of operations through the nut 15 as the screwing portion and can be firmly fastened.

Note that, instead of the nut 15, a screw hole in which the bolt 14 can be screwed is formed in the water shielding plate 12 to form a screwed portion, and the bolt 14 is inserted into the screw hole of the screwed portion. It is also possible to employ a configuration in which the hanger case 5 and the water shielding plate 12 are fastened to the bracket 6 by screwing. In this case, there is an advantage that the nut 15 is omitted and the cost can be reduced.

FIGS. 9 to 11 show a third embodiment. The present embodiment is an example in which the hanger case 5 is supported via a pair of back angles 30 provided on the inner wall la of the hoistway 1 without using the L-shaped bracket 6.

[0036] The pair of back angles 30 are arranged at predetermined intervals on the left and right sides of the inner wall la of the hoistway 1, and these back angles 30 are fixed to the inner wall la via the bracket 31. A hanger case 5 is attached between the upper ends of the back angle 30.

[0037] In this case, as the hanger case 5 provided between the upper end portions of the back angle 30, the same nonanger case 5 as in the first embodiment may be used in common. In this case, the long hole 10 exists in the horizontal plate 5a of the hanger case 5. If the long hole 10 is left as it is, when the liquid drops on the horizontal plate 5a of the hanger case 5, the liquid flows into the inside of the horizontal plate 5a through the long hole 10, and the electric contact mechanism 23 Otherwise, the electrical contact mechanism 23 may malfunction or the lock mechanism 22 may malfunction.

Therefore, in this embodiment, as shown in FIGS. 10 and 11, a water shielding plate 12 is provided on the horizontal plate 5a of the hanger case 5, and the long hole 10 is sealed with the water shielding plate 12. It is.

The water shielding plate 12 is fastened to the horizontal plate 5a via bolts 14 and nuts 15. That is, the bolt 14 penetrates the water shielding plate 12 and protrudes to the lower surface side of the horizontal plate 5a through the long hole 10, and a nut 15 is screwed to the end of the protruding side. The water shielding plate 12 is fastened so as to be crimped to the horizontal plate 5a.

[0040] According to such a configuration, the long hole 10 is securely sealed by the water shielding plate 12, so that even if the liquid drops on the horizontal plate 5a of the hanger case 5, the liquid remains in the long hole 10. Therefore, the electric contact mechanism 23 and the lock mechanism 22 on the lower side of the horizontal plate 5a can be protected by the liquid force.

[0041] The water shielding plate 12 is not limited to being provided on the upper side of the horizontal plate 5a of the hanger case 5, but may be provided on the lower side of the horizontal plate 5a.

[0042] In each of the above-described embodiments, the structure of the door device is exemplified by a double-open type using two door panels, a single-open type using one door panel, and a plurality of two or more A multi-stage single-open type or a multi-stage double-open type using a single door panel may be used.

[0043] Furthermore, the present invention is not limited to the case where the door device is provided at the entrance / exit of the elevator hall, but the case where the door device is provided at the entrance / exit of the elevator car or both doors. Even if you are targeting a device.
