Next, with reference to FIGS. 1 to 4, details of the car 1 and the bulky reinforcing member 8 of the present embodiment will be described.

FIG. 1 is a cross-sectional view of a car 1 of the present embodiment, and FIG. 2 is a front view of a left side plate 3 on which an operation panel 7 is arranged, as viewed from the A side of FIG.

As shown in the cross-sectional view of FIG. 1, the car 1 is provided with a rectangular floor plate 2, a plurality of side plates 3 standing upright on three sides of the right, left, and rear sides of the floor plate 2, and a side of the doorway 4. It has a front side plate 5 and a car door 6 that can be opened and closed at the entrance 4. It should be noted that the square indicated by the alternate long and short dash line is the outside dimension B of the car, and by keeping the protrusion of the car 1 within this range, it is possible to avoid collision with other components when the car 1 is moved up and down.

In this car 1, three side plates 3 are arranged side by side on the left side, the back side, and the right side, respectively, and the floor plate 2, side plate 3, front side plate 5, and ceiling plate (not shown) are respectively attached by bolts and nuts. By assembling, the cab of the car 1 is formed.

An operation panel 7 is provided on the side plate 3 at the center of the left side of the car 1. The operation panel 7 is provided with a destination floor registration button for registering a destination floor and an opening/closing button for the car door 6, and may be a main operation panel operated by a general user or a wheelchair user. It may be a sub-operation panel for operating the above.

Details of the left side of the car 1 will be described with reference to FIG. As shown here, the side plate 3 having the width W1 arranged at the center of the left surface is divided into the upper plate 3a and the lower plate 3b by the operation panel 7 having substantially the same width W2.

Here, the structure and function of the bulkiness reinforcing member 8 which is attached across the operation panel 7 on the back side of the upper plate 3a and the lower plate 3b will be described with reference to FIGS. 3 and 4.

FIG. 3 is a development view and a perspective view of the bulkiness reinforcing member 8. As can be seen from the comparison of both figures, the bulky reinforcing member 8 is formed by pressing a dotted line portion of a substantially E-shaped thin plate (for example, a steel plate having a thickness of 1.6 mm) having notches 8a on both sides by pressing or the like. It is bent and integrally molded. Then, as shown in the perspective view on the right side of FIG. 3, a double-sided tape 9 is attached to the surface facing the upper plate 3a and the lower plate 3b. Although the following description will be made on the premise that the bulky reinforcing member 8 is attached with the double-sided tape 9, the bulky reinforcing member 8 may be attached using rivets or screws.

FIG. 4 is a (a) rear view, a (b) vertical sectional view, and a (c) top view of the side plate 3 at the center of the left side of the car 1.

As shown in FIG. 4B, the operation panel 7 is arranged on the side plate 3 at the center of the left surface between the upper plate 3a and the lower plate 3b. 4B, the front surface of the operation panel 7 is arranged so as to be linear with the upper plate 3a and the lower plate 3b, but the front surface of the operation panel 7 may be slightly moved back and forth.

A bulkiness reinforcing member 8 is provided on the back side of the side plate 3 at the center of the left surface. The bulky reinforcing member 8 has a total length H1 and extends from substantially the upper end of the upper plate 3a to substantially the lower end of the lower plate 3b. Here, assuming that the depth dimension of the protruding portion 7a on the back side of the operation panel 7 is L1, the bulky reinforcing member 8 is provided with a notch 8a of L2 larger than the depth dimension L1 of the protruding portion 7a. Therefore, as shown in FIGS. 4(a) and 4(b), both the upper plate 3a and the lower plate 3b can be reinforced by one bulk height reinforcing member 8 that straddles the operation panel 7, and the side plate 3 as a whole can be made. The rigidity of can be increased. Strictly speaking, the sum of the dimension L2 of the cutout 8a and the thickness L3 of the double-sided tape 9 needs to be larger than the depth dimension L1 of the operation panel 7, but the thickness L3 of the double-sided tape 9 is small and can be ignored. In this case, the dimension L2 of the cutout 8a may be determined in consideration of only the depth dimension L1 of the operation panel 7.

Further, as shown in the perspective view of FIG. 3 and FIG. 4(c), the bulky reinforcing member 8 has a substantially hat-shaped cross-sectional shape at the contact portion of the upper plate 3a or the lower plate 3b. The other parts have a substantially U-shaped cross-sectional shape. By attaching the bulky reinforcing member 8 having a highly rigid cross-section to the back surfaces of the upper plate 3a and the lower plate 3b, the side plate 3 divided by the operation panel 7 has sufficient strength. be able to.

The depth of the bulkiness reinforcing member 8 is set to a value that is within the predetermined outside cage dimension B, which is indicated by the alternate long and short dash line. By storing each member in the car outside dimension B, the car 1 can be moved up and down without interfering with the equipment in the hoistway.

According to the car 1 of the present embodiment described above, each of the upper side plate 3a and the lower side plate 3b is avoided while avoiding the protruding portion 7a of the operation panel 7 which is an obstacle in reinforcing the side plate 3 integrally. It is possible to connect them by one bulk height reinforcing member 8, and thereby, it is possible to satisfy the prescribed required strength of the side plate 3 as a whole including the upper plate 3a and the lower plate 3b which are vertically divided.

Further, in the present embodiment, the upper plate 3a and the lower plate 3b between which the operation panel 7 is arranged are reinforced by one bulky reinforcing member 8 having a substantially hat-shaped cross-sectional shape, whereby a predetermined height is obtained. Even if a force is applied to the upper side plate 3a and the lower side plate 3b, it is possible to secure the necessary strength such that the side plate 3 is not deformed more than the specified amount or plastic deformation is not generated.

In addition, by reinforcing the upper plate 3a and the lower plate 3b with a single bulky reinforcing member 8, the number of reinforcing members is reduced as compared with a structure in which the upper plate 3a and the lower plate 3b are separately provided with reinforcing members. Therefore, the manufacturing process can be simplified and the manufacturing cost can be reduced.

Second Embodiment Next, a second embodiment of the present invention will be described with reference to FIG. It should be noted that duplicate description is omitted for the common points with the first embodiment.

In the first embodiment, as shown in FIGS. 3 and 4, etc., the bulky reinforcing member 8 having a hat-shaped cross section is attached to the back surface of the side plate 3 provided with the operation panel 7. A bulky reinforcing member 8 having a substantially U-shaped cross section as shown in FIG. 6 is attached.

In the configuration of the present embodiment, the manufacturing process can be further simplified and the manufacturing cost can be further reduced by simplifying the structure of the bulky reinforcing member 8 as compared with the first embodiment, and a larger double-sided tape can be obtained. Since 9 can be used, the rigidity of the entire side plate 3 to which the bulkiness reinforcing member 8 is attached can be further increased.
