Description

  The present invention relates to a special purpose cabin-equipped vehicle in which a special purpose cabin is detachably mounted on a light truck bed.

  The penetration rate of light vehicles is increasing for reasons such as energy saving (low fuel consumption), space saving, low pollution, and preferential tax and weight tax.

  Under the current laws and regulations, the standards for mini vehicles are defined as a length of 3.40 m or less, a width of 1.48 m or less, a height of 2.00 m or less, and a displacement of 660 cc or less.

  When attaching a cabin for various purposes such as toilets and camping to a light car carrier, fixing the floor of the cabin directly to the carrier with bolts, rivets, welding, etc. is a modification, so each vehicle has its own jurisdiction. You must apply to the land transportation office for modification and get permission.

  According to the Light Vehicle Inspection Related Legal Notice (supervised by the Light Vehicle Inspection Association), it has the structure and equipment necessary for the main purpose of use, and the equipment for carrying out the special purpose on the car frame or the car body is bolts, rivets It is said that the one that is securely fixed by adhesive or welding must be within 2 m in height from the ground.

  Depending on the modification, there is a possibility that the number will be 8 (special purpose automobile), and the economics of so-called light vehicles (light trucks) may be impaired.

  On the other hand, it has become common to install temporary toilets at civil engineering construction sites and construction sites. There are two types of temporary toilets: fixed and mobile. The fixed type (see, for example, Patent Document 1) is good when the construction period is long, but the mobile type is more convenient in the case of a short period or on the site where the movement is repeated frequently. There is also a mobile type in which a toilet cabin is simply provided with wheels (see, for example, Patent Document 2), but it is difficult to move at high speed because the vehicle needs to be pulled by a vehicle. Therefore, there is a case where a temporary toilet is directly loaded on the loading platform of a light truck and is used by going up to the loading platform at the site, but the height of the temporary toilet is set so that the head does not hit the ceiling. The height from the loading platform is 2 m or more, and the height from the ground is 2.6 m or more. In this case, it violates the height restriction of the Road Traffic Law. For this reason, a temporary toilet cannot be mounted on a light truck, and it is a violation if it is not loaded more than a medium-sized truck (see, for example, Patent Document 3).

  Therefore, there is a toilet car with a structure that can change the height of the ceiling part so that it will be within 2.0m (from the ground), which is the height limit of light cars, while moving, and the height will be high when in use. It has been proposed (see, for example, Patent Documents 4 and 5).

  Patent Document 4 describes an automobile in which a peripheral wall that surrounds the loading platform of the automobile and has a ceiling is configured to be vertically extendable and provided with driving means for extending and contracting.

  Patent Document 5 describes a field support car in which a ceiling portion corresponding to a toilet space is a pop-up roof portion.

Utility Model Registration No. 3064862 JP 2001-198048 A Utility Model Registration No. 3079815 JP 2004-130838 A Japanese Utility Model Publication No. 7-13607

  In the automobile described in the above-mentioned Patent Document 4, in which the ceiling portion is configured to be extendable in the vertical direction and provided with a driving means for extending and contracting, the structure is complicated, and the vehicle cannot be extended or contracted due to a failure or the like. In some cases, it cannot be used.

  In addition, in the case of the on-site support car described in Patent Document 5, since it has a structure in which the cargo compartment is fixed to the cargo bed portion, a remodeling application is required.

  Therefore, the present invention does not violate the height restriction when a cabin such as a toilet is mounted on a light truck, and is handled as a baggage within a height of 2.5 m above the road surface permitted by the Road Traffic Law. Thus, an object of the present invention is to provide a vehicle with a special purpose cabin that can be equipped with a cabin that can make maximum use of the living space.

  In order to solve the above-mentioned problems, the specific purpose cabin-equipped vehicle of the present invention has fixed the floor surface of the specific purpose specification cabin to the light truck bed from which the side and rear cages have been removed by a manual fixing tool. It is characterized by.

  In the present invention, a manual fixing tool is used as means for fixing the cabin to the platform of the light truck. According to the minicar inspection related legal notice collection (supervised by the Minicar Inspection Association), as mentioned above, it has the structure and equipment necessary to fulfill the main purpose of use, and the equipment for carrying out special purposes on the car frame or the car body. However, bolts, rivets, adhesives, or those that are securely fixed by welding must be within 2m in height, but thumbscrews, tapes, ropes, wires, etc. Equipment attached to the loading platform is considered as luggage and can be mounted at a height of up to 2.5 meters from the ground. As a result, the cabin effective height of the cabin can be set to such a height that an adult of average height does not hit the head.

The manual fixing tool can be a thumbscrew or a fixing pin with a spring ring inserted into a hole of a fixing bolt attached to the loading platform. These fixtures are general tools that are tightened without using a tool.
The front of the cabin may have a streamlined roof that extends to the ceiling of the driver's seat. Thereby, the wind pressure at the time of driving | running | working can be released, resistance can be made small, and it leads also to a fuel consumption improvement.
The special purpose cabin may be a toilet cabin. Thereby, it can be conveniently used as a mobile toilet installed at a construction site or the like.

  According to the present invention, a structure such that a cabin such as a toilet is handled as a baggage having a height of 2.5 m or less from the road surface permitted by the Road Traffic Law without compromising the height restriction when mounting a cabin on a light truck. By doing so, it is possible to realize a vehicle with a special purpose cabin equipped with a cabin that can make maximum use of the living space.
