Description

[Detailed explanation of the invention] [Field of industrial application] This invention relates to an elevator cab, and in particular, to the structure of a simple elevator cab used in small elevators such as private residences. .

[Prior art] Figures 9 and 10 are, for example,
They are a cross-sectional view showing a conventional elevator cab shown in Publication No. 45660, and a perspective view of a main part of the elevator cab as seen from the entrance/exit side.

In the figure, 1 is the car floor of the car room, 2 is the entrance/exit of this car room, 3 is the left and right side walls of the car room, 4 is the front wall, and 5 is the wing wall. Walls 5 form the four walls of this cage. 6 is the ceiling.

A conventional elevator cab is constructed as described above, and usually has side walls 3 and front walls 4.
The wing wall 5 is divided into a plurality of parts, and the car floor 1 and ceiling 6 are each manufactured separately, and then assembled on site by tightening bolts or the like.

That is, if it is manufactured in one piece in a factory, it is inconvenient to transport and there are also problems when carrying it into the hoistway, so the structure of the elevator cab described above is widely adopted.

On the other hand, with the aging of society in recent years, the number of cases in which elevators are installed in private residences has increased. In response to this, a technique disclosed in Japanese Patent Publication No. 60-47195 is known as a small and simple structure.

[Problems to be solved by the invention] The conventional elevator cab as described above has a large number of parts, is complicated to assemble, and is heavy. Moreover, since the work for assembling the cab had to be carried out inside the hoistway on the back side of the side wall 3 and front wall 4, there was a problem in that the work efficiency was extremely poor.

Therefore, this invention was made to solve such problems, and the object is to obtain an elevator cab that has a simple structure with a small number of parts and is easy to assemble.

[Means for Solving the Problems] The elevator car according to this invention includes an upper shell material in which the ceiling and upper side walls are integrally molded, and a lower shell material in which the floor and lower side walls are integrally molded. It is formed by joining.

[Function] In this invention, the upper shell material consisting of the ceiling part and the upper side wall part, and the lower shell material consisting of the floor part and the lower side wall part are manufactured by integral molding, and the structure is assembled by joining them. Since it is an elevator car, the number of parts is small and assembly work can be done inside the car.

[Example] Fig. 1 is a cross-sectional view of an elevator cab showing an embodiment of this invention, as seen from the front.
It is a sectional view taken along the line XX in the figure.

In the figure, 7 is a ceiling part 7a and an upper side wall 7b.
This upper shell material 7 has an entrance/exit portion 7c, a reinforcing rib 7d, and an end portion 7e. Reference numeral 8 denotes a lower shell material in which a floor portion 8a and a lower side wall 8b are integrally molded in the same manner as the upper shell material 7. This lower shell material 8 has an entrance portion 8c, reinforcing ribs 8d, and an end portion 8e. have. 9 is a joining material for joining the upper shell material 7 and the lower shell material 8.

In the elevator car constructed as described above, the upper shell material 7 and the lower shell material 8 are joined at the side wall portions, and together form the car room. Also, the entrance/exit part 7c of the upper shell material 7 and the entrance/exit part 8c of the lower shell material 8 are integrally formed.

Furthermore, the details of the elevator cab will be explained in detail using diagrams.

FIG. 3 is a sectional view taken along the line Y--Y in FIG. 1, and is a sectional view of the ceiling portion 7a including the upper part of the doorway.

As shown in the figure, if the ceiling area, which is the boundary between the ceiling part 7a and the upper side wall 7b, is formed in an R shape, it will be easier to integrally mold the upper shell material 7, and the rigid image of the interior of the car will be softened. be able to.

FIG. 4 is a cross-sectional view taken along line Z-Z in FIG. 2, showing the floor portion 8a including the lower part of the entrance.

As shown in the figure, if the upper surface of the floor part 8a and the lower part of the doorway are flush with each other, water can be swept outside when cleaning the inside of the car, especially when washing with water. It also makes it easier to put in and take out luggage.
However, it is not necessarily necessary to make it flush like this, and a step may be provided.

FIG. 5 is an enlarged sectional view of section A in FIG. 1, showing details of the cross section of the joint between the upper shell material 7 and the lower shell material 8.

As shown in the figure, the upper shell material 7 and the lower shell material 8 can be easily attached by simply fitting the end portion 7e of the upper shell material 7 and the end portion 8e of the lower shell material 8 into the bonding material 9 and fixing them with adhesive or the like. It is extremely easy to work with. Furthermore, by using this bonding material 9 during bonding, the uneven surfaces of the end 7e of the upper shell material 7 and the end 8e of the lower shell material 8 will not be visible.
When manufacturing the upper shell material 7 and the lower shell material 8, this end portion 7
e and end 8e need not be completely finished. Furthermore, since the thickness of this joint is increased by the joining material 9, the rigidity will not be reduced even if the ribs 7d and the like are not provided.

FIG. 6 is an enlarged sectional view of section B in FIG. 2, and is a sectional view of a portion where the rib 7d is installed.

Since the upper shell material 7 and the lower shell material 8 of this invention are manufactured by integral molding, the ribs 7d, 8d
can be provided as appropriate to provide strength depending on the purpose of use. Therefore, even if the wall thickness is thin,
Since the upper shell material 7 and the lower shell material 8 can be obtained with high rigidity, the weight can be reduced.

The elevator car with the above configuration is
The joint part is located on the side wall, and for example, if the lower shell material 8 is temporarily fixed, only the upper shell material 7 can be moved and positioned, allowing easy assembly only indoors. Therefore, there is no need to perform assembly work between the hoistway and the back side of the side wall of the car, unlike in the conventional case, resulting in good work efficiency.

In addition, the cage of this elevator has upper shell material 7.
Since the four side walls and the upper and lower walls are formed by the and lower shell material 8, the number of parts is small and handling during transportation etc. is easy. Furthermore, since the elevator car has a cell structure, even if the upper shell material 7 and the lower shell material 8 are thin, the rigidity is high and the weight can be reduced.

Next, an embodiment of this invention will be described.

If the joint between the upper shell material 7 and the lower shell material 8 is set at the center of the side wall, the upper shell material 7 and the lower shell material 8 will have approximately the same weight and the same size, so it will be easier to use during production and transportation. Easy to handle. In addition, upper shell material 7
The joining position of the lower shell material 8 is not limited to the center of the side wall, but may be above the center of the side wall. Or, on the contrary, it may be downward. However, if the position is extremely shifted from the center of the side wall, a large difference in size will occur between the upper shell material 7 and the lower shell material 8,
This may cause inconvenience when handling.

Further, the upper shell material 7 and the lower shell material 8 may be manufactured by integral molding, and may be formed by FRP molding or drawing molding of a thin metal plate or the like.

Further, as for the molding method such as FRP molding, the molding method and material can be arbitrarily selected.

Note that the materials of the upper shell material 7 and the lower shell material 8 do not necessarily have to be the same material. For example, since the interior of the lower shell material 8 is more easily damaged than the upper shell material 7, a material having high surface hardness may be used. In addition, the upper shell material 7 and the lower shell material 8
It may be manufactured with different colors.

Alternatively, the upper shell material 7 and the lower shell material 8 may be manufactured in exactly the same shape and from the same material, so that the parts can be made common.

If the entrance/exit part 7c of the upper shell material 7 and the entrance/exit part 8c of the lower shell material 8 are formed in advance when the upper shell material 7 and the lower shell material 8 are integrally formed, the entrance/exit part 7c of the upper shell material 7 and the entrance/exit part 8c of the lower shell material 8 can be formed simultaneously by assembly. For example, this entrance/exit may be formed at the installation site by opening during assembly to match the elevator opening.

Further, the joint portion of the above embodiment can also be implemented as follows. FIG. 7 is an enlarged sectional view of a joint showing another embodiment of this invention.

As shown in the figure, without using the bonding material 9 to join the upper shell material 7 and the lower shell material 8, a serration-shaped End receivers may be formed so that they can be fitted into each other and fixed with screws 10.

In this case as well, it is preferable that the upper shell material 7 and the lower shell material 8 be assembled from the indoor side. If this method is used, the number of parts can be reduced because the bonding material 9 is not required. Further, the screws 10 allow reliable fixing. However, in this case, the upper shell material 7 and the lower shell material 8 cannot have exactly the same shape, so they cannot be made into common parts.

Furthermore, FIG. 8 is a longitudinal sectional view showing still another embodiment of this invention.

In the figure, 11 is an intermediate side wall between the upper shell material 7 and the lower shell material 8. In this manner, when implementing the present invention, the entire car may be divided into three parts, or may be further divided into a large number of parts. That is, when the entire car is divided into a large number of parts, it can be used in a car with a vertically long structure such as a special elevator that is used exclusively for moving long objects. Further, the divided structure has the advantage that it can be easily handled during manufacture and transportation.

In this way, when implementing the present invention, one or more of the left and right side walls 3, the front wall 4, and the wing walls 5, the upper side wall 7b, and the lower side wall 8b connecting between the ceiling 7a and the floor 8a. In an elevator cab consisting of a side wall section consisting of one or more of It is equipped with a lower shell material 8 made of.

By the way, the upper shell material 7 when implementing the present invention
The lower side wall portion 8b may be divided vertically into two parts on the ceiling part 7a and floor part 8a side of the conventional left and right side walls 3, front wall 4, and wing wall 5, or may be divided into three parts so that the middle part is independent. It can also be divided.

Incidentally, as a modification of the structure of this embodiment, the same effect can be obtained even if a wider bonding material 9 is used.

[Effects of the invention] As explained above, the elevator cab of this invention is manufactured by integrally molding the upper shell material and the lower shell material, and is assembled by joining them together, so the number of parts is small. Moreover, it has a simple structure and can be assembled inside the car, and can be divided into multiple parts, making it easy to transport.
