Each notch 19 opens in one direction of the width direction W (in this embodiment, the direction toward the outside of the car room). Further, as shown in FIGS. 3 and 4, a plurality of (the same number as the notch portions) hinge pressing portions 25 are provided on the inner wall (outer frame 11 side) surface of the sleeve wall 3 so as to protrude. Yes. The hinge pressing portion 25 has a form in which the head portion 25a swells more than the body portion 25b. As a specific example, in the present embodiment, each of the hinge pressing portions 25 is a pin-shaped member in which the diameter of the cylindrical head portion 25a is larger than the diameter of the cylindrical body portion 25b. In addition, it is preferable to provide a vertical reinforcing member 27 at the base of the hinge pressing portion 25. The diameter of the trunk portion 25 b of the hinge pressing portion 25 is smaller than the width of the notch portion 19 formed in the second piece 17, and conversely, the head portion 25 a is smaller than the width of the notch portion 19. It is getting bigger. In addition, the protruding length of the body portion 25 b is set to be longer than or substantially the same as the thickness of the second piece 17. The second piece 17 is attached to the sleeve wall 3 by inserting the body portion 25 b of each hinge pressing portion 25 into the corresponding cutout portion 19 and positioning the head portion 25 a outside the second piece 17. Moreover, the second piece 17 is removed from the sleeve wall 3 by relatively moving the trunk portion 25 b of the hinge pressing portion 25 toward the opening of the cutout portion 19 and retracting the trunk portion 25 b from the cutout portion 19. To be separated. In this manner, the second piece 17 is detachably attached to the sleeve wall 3.

  The stopper abutment portion 21 is provided at the upper edge portion of the second piece 17 outside the car room. The stopper abutting portion 21 is a plate-like portion extending in the thickness direction T with respect to the second piece 17 extending in the width direction W. Further, the upper portion of the stopper abutting portion 21 extends upward from the second piece 17.

  A torsion coil spring 29 is attached to the hinge 7. The torsion coil spring 29 is located above the first piece 15 and the second piece 17 and is disposed across them. One end portion 29 a of the torsion coil spring 29 is hooked on the convex portion 15 a protruding on the upper surface of the first piece 15, and the other end portion 29 b is hooked on the convex portion 17 a protruding on the upper surface of the second piece 17. .

  The stopper 9 regulates the sliding movement of the sleeve wall 3 and is configured by a plate-like member having an approximately L shape in plan view, and has a first portion 9a and a second portion 9b. The first portion 9a extends in the width direction W, and the second portion 9b extends in a direction away from the sleeve wall 3 in the thickness direction T from an end of the first portion 9a outside the car room. The stopper 9 is detachably attached to the sleeve wall 3 in the first portion 9a. As an example, in the present embodiment, a through hole 9c is formed in the first portion 9a, and a bolt shaft portion 31 (screw member) provided integrally with the sleeve wall 3 is inserted into the through hole 9c. Is done. A nut 33 is attached to the bolt shaft portion 31 that penetrates the stopper 9. Accordingly, the stopper 9 is detachably attached to the sleeve wall 3. Further, the bolt shaft portion 31 and the nut 33 are arranged on the rotation center C of the hinge 7 in a plan view or closer to the opening / closing end portion 3 a side of the sleeve wall 3 than the rotation center C. Further, the sleeve wall 3 side of the outer wall 11c of the outer frame 11 is cut away as indicated by reference numeral 11d so that the operator can easily access the nut 33 and the like.

  The relationship between the sleeve wall 3, the hinge 7, and the stopper 9 is as follows. The hinge pressing portion 25 that is integral with the sleeve wall 3 is inserted into the cutout portion 19 of the hinge 7, and the second portion 9 b of the stopper 9 is abutted against the stopper abutting portion 21 of the hinge 7. The hinge shaft portion 31 and the bolt shaft portion 31 of the sleeve wall 3, the notch portion 19 of the hinge 7, and the stopper in such a relationship that the bolt shaft portion 31 integral with the wall 3 can be inserted into the through hole 9 c of the stopper 9. The abutting portion 21, the first portion 9a, the second portion 9b, and the through hole 9c of the stopper 9 are prepared.

  Next, the operation of the sleeve wall support structure having such a configuration will be described. During normal elevator operation, the sleeve wall support structure 1 according to the present embodiment is in the state shown in FIGS. That is, as described above, the hinge pressing portion 25 is inserted into the notch portion 19 of the hinge 7, and the second portion (one side in the width direction) 9 b of the stopper 9 projects into the stopper abutting portion 21 of the hinge 7. A nut 33 is screwed to the bolt shaft portion 31 that is applied and penetrates the stopper 9. In this state, when the sleeve wall 3 is removed and replaced, the operator first opens the sleeve wall 3 as shown in FIGS. 6 and 7 are views in the same manner as in FIGS. 2 and 3 when the sleeve wall is opened. The sleeve wall 3 is rotatably supported by the hinge 7 and is rotated counterclockwise from the state shown in FIGS. 2 and 3 to the state shown in FIGS. 6 and 7.

  As shown in FIGS. 6 and 7, when the sleeve wall 3 is opened, the angles of the first piece 15 and the second piece 17 of the hinge 7 are narrower than when the sleeve wall 3 is closed. It has become. Accordingly, the angle between the end portions 29a and 29b of the torsion coil spring 29 is also narrowed. The torsion coil spring 29 is provided so as to be in an unloaded state at a position where the sleeve wall 3 is open. Therefore, the sleeve wall 3 is easily maintained in an open state without being particularly strongly held by the operator.

  Subsequently, in a state in which the sleeve wall 3 is open, the nut 33 is loosened and removed from the bolt shaft portion 31, and the stopper 9 is further removed from the bolt shaft portion 31. When the stopper 9 is attached, the second portion 9b of the stopper 9 is in contact with the stopper abutting portion 21 of the hinge 7, and therefore, the sleeve wall 3 is restricted from sliding toward the outside of the car room. However, such a restriction is eliminated by removing the stopper 9 as described above. Therefore, after removing the stopper 9, the operator slides the sleeve wall 3 toward the opening side of the cutout portion 19 as indicated by an arrow X in FIGS. 6 and 7. As a result, the hinge pressing portion 25 provided integrally with the sleeve wall 3 also slides in the same direction, and the hinge pressing portion 25 is retracted from the notch portion 19. This state is shown in FIGS. FIG. 8 is a view similar to FIG. 4, and shows a state in which the nut and stopper are removed, the sleeve wall is slid, and the hinge pressing portion is retracted from the notch portion. By retracting the hinge pressing part 25 from the cutout part 19 in this way, the hook of the head 25a of the hinge pressing part 25 on the hinge 7 is eliminated, so that the operator separates the sleeve wall 3 from the hinge 7. Remove.

  When the sleeve wall 3 is attached to the hinge 7, the operation is almost the reverse of the above. First, the sleeve wall 3 is slid in the direction opposite to the arrow X, and the hinge pressing portion 25 is notched 19 of the hinge 7. Insert into. In this case, as long as no special operation is performed, the second piece 17 of the hinge 7 is maintained in the state shown in FIGS. 6 and 7 by the action of the torsion coil spring 29 trying to restore the unloaded state. The Therefore, even when the sleeve wall 3 is attached to the hinge 7, the second piece 17 and the first piece 15 of the hinge 7 are closed (the angle formed) is reduced by the action of the torsion coil spring 29. Even when 3 is inserted into the corner cover 13, the sleeve wall 3 is less likely to interfere with the second piece 17 of the hinge 7. In the open state, the sleeve wall 3 is slid in the direction opposite to the arrow X and is detachably attached to the hinge 7. When the insertion of the hinge holding part 25 into the cutout part 19 is completed, the stopper 9 penetrating the bolt shaft part 31 integrated with the sleeve wall 3 is properly abutted against the stopper abutting part 21 of the hinge 7 Then, the nut 33 is screwed onto the bolt shaft portion 31 from above the stopper 9 to fix the stopper 9 to the sleeve wall 3. As a result, the sleeve wall 3 is restricted from moving in one direction (notch opening direction) in the width direction W with respect to the hinge 7 because the stopper 9 is in contact with the stopper abutting portion 21. Since the hinge pressing portion 25 is inserted into the notch portion 19, the movement in the other direction of the width direction W (the direction opposite to the notch opening) with respect to the hinge 7, the length direction H and the thickness direction T The movement to and is regulated. That is, the sleeve wall 3 is supported by appropriately regulating movement in three directions (six directions). In addition, since the engaging part of the hinge holding | suppressing part 25 and the notch part 19 is provided in two places with a space | interval, the three rotation aspects which make the said three directions the periphery of an axis are also controlled.

  When the nut 33 is screwed onto the bolt shaft portion 31 from above the stopper 9 and the sleeve wall 3 is fixed to the hinge 7, the sleeve wall 3 is rotated clockwise from the state shown in FIGS. 2 and FIG. 3 are closed, and the attaching operation of the sleeve wall 3 is finished.

According to the sleeve wall support structure as described above, the sleeve wall can be easily removed and supported, and can be attached and detached from the interior of the car. Therefore, the sleeve wall can be easily and reliably attached and detached without being restricted by the work space. . In addition, since the sleeve wall can be attached and detached from the car room, the maintainability is improved. Furthermore, since the sleeve wall can be replaced without removing the outer frame or the like, the maintenance cost can be reduced.
In addition, the torsion coil spring provided on the hinge is set so that the sleeve wall is in an unloaded state at the position where the sleeve wall is open, so that the sleeve wall can be easily kept open and the sleeve wall is removed. Can be further facilitated.
In addition, the bolt shaft and nut are arranged on the pivot center of the hinge in plan view, or closer to the open / close end of the sleeve wall. Can be easily accessed. In particular, when the sleeve wall 3 side of the outer wall 11c is cut out as indicated by reference numeral 11d, the access to the nut can be further facilitated.

Although the contents of the present invention have been specifically described with reference to the preferred embodiments, various modifications can be made by those skilled in the art based on the basic technical idea and teachings of the present invention. It is self-explanatory.
For example, the hinge of the present invention can be used regardless of whether or not it is generally called a hinge as long as one piece is pivotally connected to the other piece. It is.
