Description

  The present invention relates to a side plate structure of an elevator car that forms a car room.

  FIG. 6 is a plan view showing a side plate structure of a conventional elevator car, FIG. 7 is a front view showing the structure of the back side of the conventional side plate, and FIG. 8 is a plan view of the conventional side plate.

  As a prior art of this type, the side plate structure of the elevator car 11 is formed by sequentially connecting a plurality of side plates 12 attached to a car frame (not shown) to form a wall 11a of the car 11 as shown in FIG. . As shown in FIGS. 7 and 8, the side plate 12 is box-bent at both ends and folded up and down, and a reinforcing body 16 having a hat-shaped substantially cross section is provided on the back surface thereof. 12 are attached along the vertical direction.

Conventionally, U-shaped folds that face each other directly are formed at the end portions of adjacent side plates so as to constitute the thickness of the side plates, and U-shaped joints are fitted into the U-shaped folds of these adjacent side plates. In other words, there has been proposed a structure in which the surface of the side plate connected to the joint surface between the side plates facing the cab is substantially the same (see, for example, Patent Document 1).
JP-A-9-77431 (paragraph number 0015, FIG. 1)

  However, the above-mentioned conventional one has a problem that a side plate is provided with a reinforcing body in order to suppress bending when the side plate is pushed from the cab side, and it takes time and cost to create the side plate. It was. Further, in the case where a plurality of side plates are connected to each other by the latter method, since a joint is required to fill the gap between adjacent side plates, it takes time to assemble the car, and from the viewpoint of design, There was a problem in answering the customer's need to reduce the seams as much as possible.

  The present invention has been made from the above-described actual state of the prior art, and an object thereof is to provide a side plate structure for an elevator car that can simplify the structure and improve workability and design. is there.

In order to achieve the above object, the present invention provides an elevator car side plate structure in which a plurality of side plates attached to a car frame are sequentially connected to form a car wall, wherein the side plate includes a ceiling frame and a floor frame. wherein attached to the car frame, it divides a plurality of structures made of steel plate having a bent portion having a cross-section of substantially U-shape, into a plurality of surface panels having an insertion portion to be fitted into the bent portion comprising The upper part of the structure is attached to the ceiling frame, the lower part of the structure is attached to the floor frame, and the insertion part is fitted into the bent part, so that the surface panel is attached to the structure from the inside of the car. The wall is formed so that the surface panels adjacent to each other are substantially flush with each other.

  In the present invention configured as described above, the structure is first attached to the car frame, and then the surface panel is opposed to the structure from the inside of the car, and the insertion portion of the surface panel has a substantially U-shaped cross section of the structure. Mounting and fixing by fitting into the bent part. Since the structure is formed with a bent portion having a substantially U-shaped cross section, the strength required as a side plate of the car can be ensured without providing a conventional reinforcing body on the surface panel, Therefore, the structure can be simplified. In addition, since the mounting of the front panel is only to fit the insertion part into the bent part from the cab side, it is excellent in workability and does not require a conventional joint between the adjacent front panels, Therefore, the seam can be reduced to improve the design.

  According to the present invention, it is possible to simplify the structure by ensuring the necessary strength as a side plate of a car without providing a reinforcing body on the front panel, reducing the labor, cost, and weight for creating the side plate. Can be planned. In addition, since the mounting of the front panel is only to fit the insertion part into the bent part from the cab side, it is excellent in workability and does not require a conventional joint between the adjacent front panels, Therefore, the seam can be reduced to improve the design. Furthermore, since the structure of the front panel is simple and can be easily attached and detached, the cab can be renewed at low cost and in a short time.

  DESCRIPTION OF EMBODIMENTS Embodiments of a side plate structure for an elevator car according to the present invention will be described below with reference to the drawings.

  FIG. 1 is a plan view showing an embodiment of a side plate structure of an elevator car according to the present invention, FIG. 2 is a side view showing the structure of the side plate and the structure of the surface panel, and FIG. FIG. 4 is a front view of the structure, and FIG. 5 is a plan view of the structure.

  The side plate 2 forming the wall 1a of the car 1 includes a car frame, for example, a plurality of bent portions 20 that are attached to the floor frame 5 with a ceiling frame 3 at the top and a bolt 4 at the bottom and have a substantially U-shaped cross section. The structure 21 is divided into a plurality of surface panels 23 having an insertion portion 22 fitted to the bent portion 20.

  The above-described structure 21 includes, for example, a side structure 21a disposed on the side surface of the car 1 at three positions on the left and right sides, and a back structure 21b disposed on the back surface of the car 1, respectively. There are one formed with two bent portions 20 and one formed with three bent portions 20. Each structure 21 is made of a single steel plate, and a bent portion 20 is formed by subjecting this steel plate to known hemming bending as shown in FIG.

  Further, the surface panel 23 described above is disposed on the front surface panel 23 a disposed on the front surface of the car 1, the side surface panel 23 b disposed on the side surface of the car 1, and the back surface of the car 1, for example. The rear surface panel 23c. And the insertion part 22 is formed by bending the edge part of the surface panel 23 in L shape.

  In this embodiment, when assembling the side plate 2, first, the upper portion of the structure 21 is attached to the ceiling frame 3, and the lower portion thereof is attached to the floor frame 5 by the bolts 4. Next, as shown in FIG. 2, the surface panel 23 is opposed to the structure 21 from the inside of the car room, and from this state, the insertion portion 22 of the surface panel 23 has a substantially U-shaped cross section as shown in FIG. It is mounted and fixed by fitting into the bent portion 20. By sequentially performing this operation, a wall 1a is formed in which the adjacent surface panels 23 are substantially flush with each other.

  According to the present embodiment, the structure is simplified by ensuring the strength necessary for the side plate 2 of the car 1 without providing the reinforcing member on the surface panel 23, and the labor and cost for creating the side plate 2 are reduced. And weight reduction can be achieved. In addition, since the mounting of the surface panel 23 is only to fit the insertion portion 22 into the bent portion 20 from the cab side, it is excellent in workability and requires a conventional joint between the adjacent surface panels 23. Therefore, the design can be improved by reducing the joints. Furthermore, since the structure of the surface panel 23 is simple and can be easily attached and detached, the cab can be renewed at low cost and in a short time.
