  Embodiments of the present invention will be described below with reference to the drawings. However, the present invention is not limited to the following examples.

[Elevator equipment]
FIG. 1 is a front view schematically showing an elevator apparatus according to the present invention. As shown in FIG. 1, an elevator apparatus 100 according to the present invention is wound around a passenger car 1, a hoisting machine 23, a counterweight 22, and a hoisting machine 23. And a main rope 20 that connects the weight 22. Winding covers 3A (upper windproof cover) and 3B (lower windbreak cover) are provided on the upper and lower parts of the car 1, respectively. The car 1 has a substantially quadrangular prism shape, and the wind regulation covers 3 </ b> A and 3 </ b> B have a shape that tapers in a direction opposite to the car 1. As the material of the air conditioning cover, aluminum or the like is preferable.

  FIG. 2 is a perspective view of the car 1 and the wind control covers 3A and 3B of FIG. As shown in FIG. 2, the air conditioning cover 3 </ b> A extends along the longitudinal direction of the car 1 on the front surface (the surface on which the car door 11 is provided) and the rear surface (the surface opposite to the front surface) of the car 1. A pair of front and rear plate 5A, 5B arranged at the position, and a pair of side plates 6A arranged at positions where the left and right side surfaces of the car 1 are extended along the longitudinal direction of the car 1, 6B and four corner curved plates 4A, 4B, 4C, 4D which are arranged at positions corresponding to the four corners of the car 1, and connect the front and rear plates 5A, 5B and the side plates 6A, 6B; Consists of. Since the configuration of the lower conditioned cover 3B is the same as that of the upper conditioned cover 3A, the reference numerals of the respective plate members (front and rear plates, side plates, and corner curved plates) are omitted.

  The car 1 has four corners chamfered. In other words, the car 1 has four chamfered portions 40 (in FIG. 2, only one corner portion is denoted by reference numeral 40 for convenience of drawing). The corner curved surface plate of the wind regulation cover 3A, the chamfered portion 40 of the car 1, and the corner curved surface plate of the wind regulation cover 3B have the same width, and are continuous in this order along the longitudinal direction of the car 1. So connected. With such a configuration, there are no corners on the wind regulation covers 3A, 3B and the car 1, and furthermore, corners (steps) between the wind regulation covers 3A, 3B and the car 1 can be eliminated. A sufficient prevention effect can be obtained.

  In the present embodiment, a frame cover 30 is provided between the wind control covers 3A and 3B and the car 1. The frame cover 30 is obtained by attaching the frame plates 2A and 2B to the frame 8 (described later), and forms a space for storing devices mounted on the car 1.

  The upper and lower parts of the car 1 having a rectangular structure of the schematic configuration are frame plates 2A and 2B that surround four sides of a frame 8 (not shown), respectively, and a part of the frame plates 2A and 2B. The wind control covers 3A and 3B are fixed after being arranged.

  Similarly to the car 1, the frame cover 30 also has chamfered portions 41 at four corners. The chamfered portion 41 includes a curved corner plate of the conditioned cover 3A, the chamfered portion 40 of the cab 1, and the conditioned cover 3B. It has the same width as the corner curved surface plate, and is connected to the corner curved surface plate of the wind regulation cover 3A and the chamfered portion 40 of the car 1 so as to be continuous. By adopting such a configuration, even when the frame cover 30 is provided, corners are generated between the frame cover 30 itself, the frame cover 30 and the wind regulation cover 3A, and the frame cover 30 and the car 1. In this way, a wind noise prevention effect can be sufficiently obtained.

  FIG. 3 is a side view schematically showing a part of the air conditioning cover 3A, the frame cover 30 and the car 1 of FIG. 2 (viewed from the direction of the arrow in FIG. 2). As shown in FIG. 3, the wind control cover 3A of the elevator apparatus according to the present invention is provided between the front and rear plates 5A and 5B and the side plates 6A and 6B (in FIG. 3, the front and rear plates 5A and the side portions). Between the front and rear plates 5A and 5B and the frame plates 2A and 2B (in FIG. 3, the portion indicated by B between the front and rear plates 5A and the frame plate 2A). , Between the frame cover 30 and the car 1 (in FIG. 3, C between the frame plate 2A and the front surface 12 of the car 1) and the wind control covers 3A and 3B, the frame cover 30 and the four corners of the car 1 It can be configured without generating corners. Therefore, it is possible to sufficiently obtain the wind noise prevention effect of the wind cover. As described above, in the structure of the conventional Patent Documents 1-3, corner portions are generated between the plate members, between the wind-control cover and the ride car, etc., and thus the wind noise prevention effect of the wind-control cover may not be sufficient. (Patent Document 2 has a corner portion in FIG. 3 and Patent Document 3 has a corner portion in FIG. 3).

  4 is an exploded perspective view of the air conditioning cover 3A of FIG. 1, and FIG. 5 is a perspective view of the corner joint component 7A of FIG. As shown in FIGS. 4 and 5, the wind regulation cover 3A may be composed of one member, but the front and rear plate 5A and the side plate 6A are divided into two in the circumferential direction of the wind regulation cover 3A. The corner connecting parts 7A, B, C, D in which the front and rear part plates, the side part plates, and the corner curved surface plates are integrally formed are prepared, and the wind is adjusted using the corner connecting parts 7A to 7D. The cover 3A may be configured. In this way, by configuring the wind control cover 3A with a plurality of parts, the manufacture of the wind control cover is facilitated, and the assembly work can be facilitated.

  The corner joint component 7A is obtained by joining the corner curved surface plate 4A, the front and rear plate 5A, and the side plate 6A. The corner joint component 7B is obtained by joining the corner curved surface plate 4B, the front and rear portion plates 5B, and the side portion plates 6A. The corner joint component 7C is obtained by joining the corner curved plate 4C, the front and rear plates 5B, and the side plates 6B. Further, the corner joint component 7D is obtained by joining the corner curved surface plate 4D, the front and rear portion plates 5A, and the side portion plates 6B. The air conditioning cover 3A may be divided into three or more parts, but it is preferably divided into two parts in order to reduce the number of parts and make the structure as simple as possible.

In this step, the corner joint components 7A to 7D are prepared, and the corner joint components 7A to 7D are arranged while being aligned with the four corners of the frame component 8, respectively. The corner connecting component 7A is positioned such that the corner curved surface plate 4A, the chamfered portion 41 of the frame cover, and the chamfered portion 40 of the car 1 are continuously connected along the longitudinal direction of the car 1. Align. The other corner joint components 7B to 7D are similarly aligned. The bottom sides of the corner joint components 7A to 7D are made to coincide with the four corners of the frame component 8 and the frame plates 2A and 2B, and can be easily aligned.

  FIG. 9 is a perspective view schematically showing a fourth step of the assembling step of the air conditioning cover. After the corner joint components 7A to 7D are aligned in the third step, the corner joint components 7A to 7D are fixed to the frame component 8 and the frame plates 2A and 2B, and then each corner joint component 7A. Fix between ~ 7D. A window portion (inspection window) 9 formed by being surrounded by the front and rear plate 5A and the frame cover 30 to be disposed on the front side of the car 1 may be entered by an operator for inspection on the car. It is for making it possible.

  FIG. 10 is a perspective view schematically showing a fifth step of the assembling step of the air conditioning cover. When the window portion 9 is opened in a steady state, a large wind noise is generated. Therefore, the front cover 10 is attached so as to close the window portion 9. FIG. 11 is a diagram schematically showing a state in which the assembly of the wind-tuning cover is completed. The air conditioning cover 3B is assembled in the same manner as the air conditioning cover 3A.
