Abstract

PROBLEM TO BE SOLVED: To provide an elevator car equalizing fundamental parts constitution of car side plates and a car ceiling.SOLUTION: Each of the car side plates 2, wing walls 3, upper plates 4 and the car ceiling 5 constituting a car 1 is formed with a panel A shaped into a box shape by folding four corners, reinforcing members B with a cross-sectional shape of a hat-shape or a squared U shape are attached to the rear surfaces of the car side plates 2, the wing walls 3, the upper plates 4, and the car ceilings 5, and thereby required strength according to a use position is secured.

Description

  The present invention relates to an elevator car that assembles panels and forms a car side plate, a sleeve wall, a top plate, and a car ceiling.

  In general, the elevator car has a car floor, a car side plate that forms the car wall surface (including a sleeve wall standing on the side of the car doorway, and an upper plate arranged at the upper part of the car doorway), and the upper part of the car. It consists of a covered ceiling. These parts are assembled by fastening each part with bolts, and become a car.

  The car side plate and the car ceiling are both made of thin steel plates, but the shapes are completely different. The reason is that the concept of strength is different and the production lines are different. Further, the structure of the car side plate is such that the left and right ends of the panel are bent in a U-shape, and the upper and lower ends in contact with the car floor or the car ceiling are bent in an L shape. In order to ensure the strength of this panel, a U-shaped or hat-shaped reinforcement is attached to the back side. Furthermore, the structure of the car ceiling may or may not be divided depending on the size of the car. In either case, the four sides of the panel are bent into an L shape or a U shape, and the L side or A square-shaped reinforcement is attached.

  In the car configured as described above, in order to increase the strength of the panel, it is necessary to form a folded portion at the end of the panel. Therefore, conventionally, the panel is attached to the frame from the inside, the panel and the frame are integrated, the strength of the panel is increased, and it is not necessary to form a folded portion at the end of the panel, thus simplifying the structure of the panel Have been proposed (see, for example, Patent Document 1).

JP 2005-60009 (paragraph number 0009-0010, FIG. 4)

  However, in general elevator cars, even in the above-described conventional one, the car side plate (the sleeve wall standing on the side of the car entrance / exit, the upper plate arranged on the upper part of the car entrance / exit) And the car ceiling have different parts shapes and parts configurations, and it is necessary to provide a plurality of production lines, and the number of parts is large and the design is complicated.

  The present invention has been made from the above-described prior art, and an object of the present invention is to provide an elevator car that can have the same basic component configurations of a car side plate, a sleeve wall, an upper plate, and a car ceiling. It is in.

  To achieve the above object, the present invention provides an elevator car comprising a car side plate, a sleeve wall, an upper plate, and a car ceiling, the car side plate, the sleeve wall, the upper plate, and the car. Each of the ceilings is formed from a box-shaped panel that is bent at four corners, and a hat-shaped cross-sectional shape or a corner of the cage side plate, the sleeve wall, the upper plate, and the rear surface of the cage ceiling. A reinforcing member having a letter-shaped cross-sectional shape is attached.

  In the present invention configured as described above, each of the car side plate, the sleeve wall, the upper plate, and the car ceiling is formed of a box-shaped panel, that is, a panel having the same cross-sectional shape, and a hat shape. By attaching the reinforcing member having the cross-sectional shape of the above or the U-shaped cross-sectional shape to the back side of the car side plate, the sleeve wall, the upper plate, and the car ceiling, the necessary strength according to the use site is secured. Accordingly, the basic component configurations of the car side plate, the sleeve wall, the upper plate, and the car ceiling can be made the same.

  According to the present invention, it is possible to unify the production line and reduce the number of parts by using the same basic parts configuration of the car side plate, the sleeve wall, the upper plate, and the car ceiling. Productivity is improved. In addition, the design efficiency is improved because the design side also performs design using standardized parts. Therefore, it is possible to reduce the overall cost of the entire car including design to manufacturing.

It is a whole lineblock diagram showing one example of a passenger car of an elevator concerning the present invention. It is explanatory drawing of the panel which forms a passenger car. It is explanatory drawing of the reinforcing material which has a hat-shaped cross-sectional shape. It is explanatory drawing of the reinforcing material which has a U-shaped cross-sectional shape.

  Embodiments of elevator cars according to the present invention will be described below with reference to the drawings.

  As shown in FIG. 1, the elevator car 1 of the present embodiment has a car side plate 2 erected on three sides excluding the car doorway, a sleeve wall 3 erected on the side of the car doorway, and an upper part of the car doorway. As shown in FIG. 2, the upper plate 4 and the car ceiling 5 that covers the upper part of the car are arranged, and the car side plate 2, the sleeve wall 3, the upper plate 4, and the car ceiling 5 are provided. The panel A is formed by bending the four corners into a box shape. The car side plate 2, the sleeve wall 3, the upper plate 4, and the car ceiling 5 are composed of a combination of a panel A and a reinforcing material B that is attached to the back surface of the panel A and reinforces the panel A. Then, the car side plate 1 panel A and the car ceiling 2 panel A are assembled with bolts and nuts (not shown) to form the car 1.

  As shown in FIG. 2, the end of the panel A is folded in four directions to form a box shape. The width dimensions L1 and W1 and the thickness dimension H1 of the panel A can be arbitrarily set according to the use site.

  Meanwhile, as the reinforcing material B, as shown in FIG. 3, a reinforcing material B1 having a hat-shaped cross-sectional shape and a reinforcing material B2 having a U-shaped cross-sectional shape as shown in FIG. Use them according to your needs. Further, the length dimension L2 of the reinforcing material B1 and the length dimension L3 of the reinforcing material B2 are arbitrarily set according to the panel A to be attached.

  In the present embodiment, the car side plate 2, the sleeve wall 3, the upper plate 4, and the car ceiling 5 are configured by a combination of the panel A and the reinforcing material B, but are required in each part. Since the strengths of the reinforcing members B1 and B2 are different from each other, it is possible to select one that is suitable for the part among the reinforcing members B1 and B2, or to change the number of attachments and attachment positions of the reinforcing members B1 and B2.

  According to the present embodiment, by making the basic component configurations of the car side plate 2, the sleeve wall 3, the upper plate 4 and the car ceiling 5 the same, the production line can be unified and the number of parts can be reduced. Can improve productivity. In addition, the design efficiency is improved because the design side also performs design using standardized parts. Therefore, it is possible to reduce the overall cost of the entire car 1 including design to manufacturing.
