Abstract

PROBLEM TO BE SOLVED: To improve assembling efficiency and to reduce the number of part items so as to increase rigidity by inserting a ceiling part into each of left and right side plates when the ceiling part is fixed to the left and right side plates by the fitting structure of ceiling irregular parts provided in both left and right ends of the ceiling part. SOLUTION: Recessed parts 2a to be fitted in the upper parts 3a and 4a of left and right side plates 3 and 4 are provided in both left and right ends of a ceiling part 2 in a deep side direction. The center upper parts of the left and right side plates 3 and 5 are formed to be irregular so as to provide space in the vertical direction of a car 1 and cross the uneven parts of a horizontal direction provided in the center parts of the side plates 3 and 4. Thus, since the ceiling part 2 is moved left and right during assembling of the car 1 and the necessity of adjustment for fixing in the left and right side plats 3 and 4 is eliminated, assembling is facilitated and the recessed and projecting parts of the vertical and horizontal direction cross each other. Accordingly, the rigidity of the car is far larger compared with flat plate one.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a car structure for a low-rise residential elevator.

[0002]

2. Description of the Related Art A conventional elevator car structure uses a steel plate as disclosed in Japanese Patent Application Laid-Open No. 4-11683, and forms one ceiling by combining a plurality of bent steel plates.

[0003]

For this reason, since a plurality of steel plates are combined in order to allow the ceiling to have a wide space, the number of parts is increased, the assemblability is poor, and the work time during installation is long. There was a problem.

[0004] It is an object of the present invention to provide an elevator car structure in which parts are reduced, assembly efficiency is improved, and car rigidity is improved.

[0005]

In order to achieve the above object, the present invention provides a structure in which the right and left ends of a ceiling are concave and convex, and the concave and convex portions of the ceiling are fitted in the front and rear directions of upper portions of left and right side plates.
When the ceiling is fixed to the left and right side plates, the ceiling is sandwiched between the left and right side plates.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a perspective view of the entire car of the present invention. FIG. 2 is a perspective view of the car shown in FIG. FIG. 3 is a plan view showing details of the front pillar.

In these figures, a car 1 is formed of a ceiling portion 2, left and right side plates 3 and 4, a rear side plate 5, a door stop pillar 6 and an upper pillar 7, and the ceiling portion 2 is formed of left and right side plates 3, 4 is fitted to the upper part. The rear side plate 5 has a structure to be fitted between the left and right side plates 3 and 4, the door stop column 6 is on the side plate 4 on the opposite side of the side plate 3 where the operation panel 3b is located, and the upper column 7 is the entrance and exit of the ceiling 2 with arrows. Fixed on the side. The ceiling 2 and the left and right side plates 3 and 4 are made of a material such as reinforced plastic. The ceiling part 2 has a shape symmetrical in the front and back with respect to the depth side, and has a convex structure at the center to provide a space for mounting a lighting fixture. The left and right ends of the ceiling 2 are concave structures 2a so that they can be fitted into the upper portions 3a, 4a of the left and right side plates 3, 4 in the depth direction. The positioning in the left-right direction can be performed only by fitting the concave portion 2a of the ceiling portion 2 into the left and right side plate upper portions 3a, 4a. Therefore, when assembling the car 1,
There is no need to move the ceiling 2 in the left-right direction and make adjustments for fixing the ceiling 2 to the left and right side plates 3 and 4. Left and right side plates 3, 4
Has a concavo-convex structure in which the upper central portion is extended in the vertical direction of the car 1. The central portions of the side plates 3 and 4 also have an uneven structure in the horizontal direction, so that the unevenness in the vertical direction and the unevenness in the horizontal direction are connected. Because of the structure in which the uneven portions in the vertical and horizontal directions are crossed in this manner, the rigidity of the car is much higher than that of a flat plate.

FIG. 3 shows a second embodiment. In the first embodiment, the left and right ends of the ceiling portion 2 have the recess 2a structure. However, as shown in FIG. 3, a part of the recess 2a at both ends of the ceiling portion 2 is provided at one location in the depth direction. Alternatively, the structure 2b has a plurality of cutouts. Left and right side plates 3, 4
As for the side plate upper portions 3a and 4a, a part of the recessed notch 2
One or a plurality of portions in the depth direction are formed as the convex structure 4c so as to be fitted in b. To assemble the car 1, the ceiling 2, the recessed notch 2 b are connected to the upper side plates 3 a, 4.
By fitting into the convex portions 3c and 4c of a, positioning in the left-right direction and the front-back direction in the depth side can be performed.
Work time can also be reduced.

According to this embodiment, the left and right ends of the ceiling of the car have an uneven structure, and the uneven portions of the ceiling are fitted in the front-rear direction of the upper portions of the left and right side plates. Is inserted into the left and right side plates, thereby making it unnecessary to adjust the fixed position of the ceiling and the left and right side plates in the left and right direction, thereby improving the rigidity of the car, reducing the number of parts, and improving the assembly efficiency.

[0011]

According to the present invention, the right and left ends of the ceiling portion of the car have an uneven structure, and the uneven portions of the ceiling are fitted into the front and rear directions of the upper portions of the left and right side plates. By inserting the parts into the left and right side plates, it is not necessary to adjust the fixed position of the ceiling and the left and right side plates in the left and right direction, so that the rigidity of the car is improved, the number of parts is reduced, and the assembling efficiency is improved.
