Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a vehicle toilet structure and a manufacturing method thereof.
The present invention particularly relates to a vehicle toilet structure suitable for use in railway vehicles and a manufacturing method thereof.

[Prior art] The toilet structure in conventional railway vehicles was developed in U.S. Pat.
As described in Publication No. 8969, the structure is such that the entire toilet structure is assembled as one body outside the vehicle body, and then carried into the vehicle through a dedicated opening formed in the vehicle body to carry the toilet structure into the vehicle. was.

In addition, as described in Japanese Utility Model Publication No. 59-5647, the entire toilet structure is integrally molded with reinforced plastic, and interior items such as a toilet bowl and a washbasin are sequentially placed inside the toilet structure. It was supposed to be installed.

Furthermore, as described in Japanese Patent Publication No. 44-29768, the toilet bowl, sink pipe, etc. are integrally constructed and attached to the vehicle body, while the toilet structure integrally formed outside the vehicle body is opened through a special opening for carrying in. The structure was such that the toilet was brought in and installed in correspondence with the toilet bowl, etc.

[Problems to be Solved by the Invention] The above-mentioned conventional technology has a structure in which the toilet structure is assembled outside the vehicle body and then carried into the vehicle through a dedicated loading opening and installed. The structure of the floor part was devised to correspond with the toilet bowl etc. installed on the car body side. In addition, the installation structure for various equipment has been devised so that the toilet structure is integrally molded from reinforced plastic. Therefore, sufficient consideration has not been given to the structure of the toilet structure itself or its manufacturing method.

In other words, the toilet structure integrally molded outside the car body is carried into the car through an opening installed in the end portion or side gutter of the car body for carrying in, and post-treatment of the carrying opening, especially rain leaks, is carried out. There were problems such as countermeasures or an increase in the number of parts.

Furthermore, since the toilet structure is an integrally molded product made of reinforced plastic or the like, it requires a great deal of labor and time to install decorative sheets or the like as interior materials, which is disadvantageous in terms of improving interior decoration.

An object of the present invention is to provide a vehicle toilet structure that can be installed inside a vehicle without providing an opening in the vehicle body exclusively for carrying in the vehicle.

Another object of the present invention is to provide a vehicle toilet structure and a toilet assembly method that can be easily assembled in a narrow space inside a vehicle.

[Means for solving the problem] In order to achieve the above object, there is provided a lower unit whose dimensions are shorter than the size of the opening in the vehicle body and whose wall surfaces excluding the floor and entrances are integrally formed, and which is installed above the lower unit. The vehicle is constructed of a plurality of wall panels whose dimensions are shorter than the size of the vehicle body opening portion and which are divided in the vertical direction, and a ceiling panel installed at the upper opening of the plurality of wall panels.

In order to achieve the other objectives mentioned above, a lower unit that integrally constitutes the lower part of the toilet, and a lower unit installed above the lower unit,
It is composed of a wall panel divided into at least two parts in the vertical direction, and a ceiling panel provided above the wall panel.

Furthermore, in order to achieve the other objectives mentioned above, a lower unit that integrally forms the lower part of the toilet, a split-type wall panel installed on the lower unit, and a ceiling panel installed on the upper part of the wall panel are installed on the vehicle body. After the lower unit is carried in through the opening and installed on the vehicle body frame, a wall panel is installed on the lower unit, and a ceiling panel is further installed on the upper part of the wall panel. .

[Function] The lower unit, the wall panel, and the ceiling panel are not used as conventional openings for carrying in toilet components, but rather as openings for carrying in the vehicle body, such as the end passageway or entrance/exit platform that is inevitably formed in the vehicle body. Since the size of the opening is shorter than the required opening, there is no need to install a special opening in the car body, and the toilet can be easily carried into the car and assembled to form a toilet.

In addition, the structure is composed of a lower unit, a split-type wall panel installed above the lower unit, and a ceiling panel installed above the wall panel, and each of the above members is configured on the vehicle body side. They are connected to each other independently of each other, and can be easily assembled inside a narrow vehicle.

In addition, a special jig is required to assemble the lower unit from the bottom by installing the lower unit on the vehicle underframe, then installing the wall panel on top of the lower unit and installing the ceiling panel on top of the wall panel. Or, without any complicated work,
It can be easily assembled even in a narrow space inside the car.
