Description

The present invention relates to a separate-type camping trailer in which the main body of the camping trailer can be divided into two and slid to expand the interior space.

Conventional camper trailers are subject to operating conditions that prohibit passengers from riding in them while they are moving, but their characteristic structure is that the towing vehicle and the trailer are connected by a coupler. In other words, once the towing vehicle and the trailer are separated, the towing vehicle (a private car) can travel freely anywhere on its own.
Therefore, unlike conventional large self-propelled camper trailers, these trailers are more maneuverable at the travel destination, making it easy to sightsee and shop locally, greatly increasing the freedom and enjoyment of the trip. In addition, the shape and arrangement of the seats inside the trailer can be freely designed, and the size of the vehicle and interior specifications can also be designed to reflect a wide range of user preferences, so demand for them as a means of transportation for overnight drive trips is increasing in recent years.

A wide variety of campervans have been developed to reflect such diverse user preferences. For example, a "camping shell" (Patent Document 1) has been proposed, in which a camping shell placed on the bed of a freight vehicle can be rotated to create space inside the vehicle.

However, since the proposed "camping shell" employs a means for manually rotating a camping shell of a certain weight placed on the bed of a freight truck, it was necessary to solve the following problems.
- Passenger cars are limited to freight vehicles with loading platforms.
・A certain height and strength are required to manually rotate a shell of a certain weight.
- There is no safety device when rotating it, so it is dangerous.
- It is not possible to store fixtures inside the rotating shell.
-Stairs are required to enter the shell.
- The interior space is narrow because the deployed shell is pulled out in a stepped or arc shape.
There were many problems such as:

In addition, a "camper" has been proposed (Patent Document 2) in which a cabin equipped with casters can be slidably inserted and removed from the rear loading platform of the camper.

However, since the proposed "camper" employs a means for storing a cabin in the rear cargo bed of the camper, it was necessary to solve the following problems.
- Passenger cars are limited to large minivans with a stowable cabin.
-The cabin needs to be smaller than the storage space of a camper van, so the interior space is narrow.
-Since camper vans and cabins are custom made, the vehicle production costs and vehicle purchase prices will rise.
- The interior space of the towing vehicle is limited when the cabin is stowed while driving.
- Sleeping space is limited to the rear cargo space of the minivan.
・The installation work and structure of the cabin skirt are complicated.

The separate type camping trailer of the present invention overcomes many of the problems mentioned above.
By dividing the body of the camper trailer into two and sliding it, the interior space can be expanded and driving comfort can be improved.
・Since used cars are driven by rear wheels, the vehicle space is made flatter and the center of gravity of the vehicle body is lowered.
・The body frame of the camper trailer and the body frame of the used car are the same, so the body rigidity is high.
-The ceiling height of the vehicle body is designed for sitting and walking rather than standing, which makes it possible to make the camper trailer lighter and more compact.
- The advanced vehicle design performance of existing used cars can be utilized.
- Instead of the traditional original handmade production, this is a modified production using existing used cars, which allows for significant reductions in manufacturing costs.
- Because the vehicle design will reuse the body design of existing used cars except for the front part, it will be possible to reuse the width lights, turn signals, stop lights, interior lights, license plate lights, hazard lights, locking keys, automatic door lock devices, and window opening and closing devices that are built into the body of existing used cars.
- The short wheelbase of the rear wheels of the towing vehicle and the wheels of the main body of the vehicle improves driving performance.
・Sleeping space can be easily secured by simply pulling out the rear sliding cabin from the main body.

Conventional manufacturing methods for camper vans and camper trailers have relied mainly on handmade production, where each vehicle is finished by hand, which has led to problems such as high vehicle prices, long delivery times, inability to procure repair parts, long repair periods, and high repair costs. At the same time, compared to existing used cars, these vehicles do not have the vehicle design performance required for compactness, light weight, drivability, exterior design, versatility, robustness, waterproofness, soundproofing, durability, weather resistance, safety, and convenience.
Furthermore, many conventional camper vans and camper trailers tend to be large, equipped with sleeping beds, sofas, camping equipment, kitchens, toilets, showers, entertainment equipment, etc., and allowing the user to stand and walk around inside. As a result, coupled with housing conditions unique to Japan, such as high purchase prices, being large and difficult to drive, and requiring a large parking space, these have been factors that have prevented them from becoming widely popular.

In light of the above problems, the applicant envisioned a camping trailer that is low-cost, compact, and easy to drive compared to the large, luxuriously equipped, high-priced camping trailers that have been popular up until now. This led to the development of a separate-type camping trailer in which the main body of the camping trailer can be divided into two and slid to expand the interior space, which led to the proposal of the "separate-type camping trailer" of the present invention.

R Interior space U Used car

The present invention relates to a separate type camper trailer in which the body of an existing used car is divided into three parts and a sliding function is added to expand the interior space.

Conventional camper trailers are subject to operating conditions that prohibit passengers from riding in them while they are moving, but their characteristic structure is that the towing vehicle and the trailer are connected by a coupler. In other words, once the towing vehicle and the trailer are separated, the towing vehicle (a private car) can travel freely anywhere on its own.
Therefore, unlike conventional large self-propelled camper trailers, these are more maneuverable at the travel destination, making it easy to sightsee and shop locally, greatly increasing the freedom and enjoyment of the trip. In addition, the shape and arrangement of the seats inside the trailer can be freely designed, and the size of the vehicle and interior specifications can also be designed to reflect a wide range of user preferences, so demand for them as a means of transportation for overnight drive trips is increasing in recent years.

A wide variety of campervans have been developed to reflect such diverse user preferences. For example, a "camping shell" (Patent Document 1) has been proposed, in which a camping shell placed on the bed of a freight vehicle can be rotated to create space inside the vehicle.

However, since the proposed "camping shell" employs a means for manually rotating a camping shell of a certain weight placed on the bed of a freight truck, it was necessary to solve the following problems.
- Passenger cars are limited to freight vehicles with loading platforms.
・A certain height and strength are required to manually rotate a shell of a certain weight.
- There is no safety device when rotating it, so it is dangerous.
- It is not possible to store fixtures inside the rotating shell.
-Stairs are required to enter the shell.
- The interior space is narrow because the deployed shell is pulled out in a stepped or arc shape.
There were many problems such as:

In addition, a "camper" has been proposed (Patent Document 2) in which a cabin equipped with casters can be slidably inserted and removed from the rear loading platform of the camper.

However, since the proposed "camper" employs a means for storing a cabin in the rear cargo bed of the camper, it was necessary to solve the following problems.
- Passenger cars are limited to large minivans with a stowable cabin.
-The cabin needs to be smaller than the storage space of a camper van, so the interior space is narrow.
-Since camper vans and cabins are custom made, the vehicle production costs and vehicle purchase prices will rise.
- The interior space of the towing vehicle is limited when the cabin is stowed while driving.
- Sleeping space is limited to the rear cargo space of the minivan.
・The installation work and structure of the cabin skirt are complicated.

The separate type camping trailer of the present invention overcomes many of the problems mentioned above.
· By dividing the body of the camper trailer into three parts and adding a sliding function, it is possible to expand the interior space and improve driving performance.
・Since used cars are driven by rear wheels, the vehicle space is made flatter and the center of gravity of the vehicle body is lowered.
・The body frame of the camper trailer and the body frame of the used car are the same, so the body rigidity is high.
-The ceiling height of the vehicle body is designed for sitting and walking rather than standing, which makes it possible to make the camper trailer lighter and more compact.
- The advanced vehicle design performance of existing used cars can be utilized.
- Instead of the traditional original handmade production, this is a modified production using existing used cars, which allows for significant reductions in manufacturing costs.
- Because the vehicle design will reuse the body design of existing used cars except for the front part, it will be possible to reuse the width lights, turn signals, stop lights, interior lights, license plate lights, hazard lights, locking keys, automatic door lock devices, and window opening and closing devices that are built into the body of existing used cars.
- The short wheelbase of the rear wheels of the towing vehicle and the wheels of the main body of the vehicle improves driving performance.
・Sleeping space can be easily secured by simply pulling out the rear sliding cabin from the main body.

Conventional camper trailer manufacturing methods have relied mainly on handmade production, where each trailer is finished by hand, which has led to problems such as high vehicle prices, long delivery times, difficulty in procuring repair parts, long repair periods, and high repair costs. At the same time, compared to existing used cars, camper trailers do not have the vehicle design performance required for compactness, light weight, drivability, exterior design, versatility, robustness, waterproofness, soundproofing, durability, weather resistance, safety, and convenience.
Furthermore, many conventional camper trailers tend to be large, equipped with sleeping beds, sofas, camping equipment, kitchens, toilets, showers, entertainment equipment, etc., and allowing the user to stand and walk around inside. As a result, coupled with housing conditions unique to Japan, such as high purchase prices, being large and difficult to drive, and requiring a large parking space, these have been factors that have prevented them from becoming widely popular.

The applicant has taken the above problems into consideration and envisaged providing a camper trailer that is low-cost, compact and has excellent manoeuvrability compared to the large, luxuriously equipped, high-priced camper trailers that have been prevalent up until now. With this in mind, the applicant developed a separate-type camper trailer that can expand the interior space by dividing the main body of an existing used car into three parts and adding a sliding function , which has led to the proposal of the "separate-type camper trailer" of the present invention.
