Description

The present invention relates to a camper trailer that utilizes existing used cars to achieve low prices, while at the same time offering excellent vehicle design performance, including compactness, light weight, drivability, exterior design, versatility, robustness, waterproofness, soundproofing, durability, weather resistance, safety, convenience, and ease of procurement of repair parts.

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, they are more maneuverable, making it easier to sightsee and shop locally, greatly increasing the freedom and enjoyment of the trip. 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 camper vans have been developed to reflect such diverse user preferences. For example, a "Camper Van Box and Camper Van" (Patent Document 1) has been proposed that allows for a large amount of storage space and has excellent heat insulation properties.

However, the proposal for the "Camper Box and Camper" involved fitting a camper box that can greatly expand the storage space to an existing vehicle, which limited the base vehicle to be a luggage vehicle and made it unsuitable for long drives in terms of ride comfort. Furthermore, the camper box itself was custom-made, which resulted in a high vehicle purchase price, and in order to make the camper long enough for an adult to sleep inside, it had to be attached to a larger camper that was one size larger in height.

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, this "camper" proposal involves storing the cabin in the rear cargo area of the camper, which means that the cabin needs to be smaller than the storage space of the camper, and because the camper and cabin are custom-made, the vehicle manufacturing costs and vehicle purchase prices are high.

In addition, a "camper van conversion kit and conversion method using said kit" (Patent Document 3) has been proposed, which allows a person to convert their own car into a camper van and create a living space that is as large as possible.

However, the proposed "camper van conversion kit and conversion method using said kit" has a structure in which the conversion kit is attached to the cargo bed behind the driver's seat of the base vehicle, which means that the cabin itself needs to be smaller than the storage space of the camper van, which means the living space tends to be narrow and it is difficult to ensure sufficient sleeping space. In addition, because the cabin is custom-made, the vehicle production cost and vehicle purchase price are high.

In addition, previous proposals for camper trailers include, for example, a towed vehicle that can provide on-site service at a desired location and can provide a business opportunity for people who are hindered by lack of start-up capital, and a "towing vehicle or a method of providing services to a towing vehicle" that can provide services together with the towed vehicle (Patent Document 4).

However, the proposal for the "towing vehicle or method of providing services to a towing vehicle" was a proposal for the internal layout structure of the towed vehicle, and did not have any particularly significant structural features compared to conventional camper trailers.

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, they have not been as compact, lightweight, drivable, stylish in exterior design, versatile, robust, waterproof, soundproof, durable, weather-resistant, safe, or convenient.
In addition, conventional camper vans and camper trailers have tended to be large, equipped with sleeping beds, sofas, camping equipment, kitchens, toilets, showers, entertainment equipment, etc., and allowing passengers to stand and walk around inside. As a result, they have been expensive to purchase, large and difficult to drive, and require a large parking space, which, combined with housing conditions unique to Japan, have meant that they have not become widely used.

The applicant has taken the above problems into consideration and envisioned a camper trailer that is low-cost, compact, and easy to drive compared to the large, luxuriously equipped, high-priced camper trailers that have come into widespread use up until now. The applicant has developed a camper trailer that achieves a low price by utilizing existing used cars, and that also has excellent vehicle design performance, such as compactness, light weight, driveability, exterior design, versatility, robustness, waterproofness, soundproofing, durability, weather resistance, safety, convenience, and ease of procurement of repair parts, which has led to the proposal of the "camper trailer" of the present invention.

The ground fixing device 18 is provided, for example, on both sides of the front lower side of the body frame 12 of the camper trailer 10, and is folded inward and stored when traveling, and when fixing to the ground, it is opened outward from the folded state and the handle part is rotated to place the installation and fixing foot on the ground and fix it in place.
In addition, by using auxiliary wheel tires with stoppers as the installation and fixing feet, the camping trailer 10 can be moved in the installed state.

The front body cover 22 is formed and attached in a shape that expands the interior space R in the opened front part by removing the windshield part 19, bonnet part 20, headlamp part 21, and wiper part 25 that are attached to the front part of the vehicle body 11 of an existing used car U to open the front part.
As for the shape, for example, it can be formed into a streamlined shape that reduces air resistance in the front, and the outer peripheral edge of the windshield portion 19 removed from the used car U can be processed to form a front view window.

The shape of the front body cover 22 is divided into a medium-sized car finish and a small car finish, and the part that comes into contact with the front grille and headlamp section 21 during installation is processed by hand to match the shape of the existing used car U, making it possible to standardize and mass-produce the front body cover 22, and the shape is not specified.

Furthermore, if the material of the front body cover 22 is, for example, FRP, steel plate, aluminum plate, synthetic resin material, etc., the shape design can be provided with a variety of vehicle body design designs according to the user's preferences and model year.

The tire house cover 24 is formed in a substantially semicircular door shape that can be opened and closed freely to cover the tire house 23 formed on both front sides of an existing used car U, and by closing the bottom of the tire house 23 with a bottom plate and attaching the bottom plate with hinges or the like so that it can be opened and closed freely, the tire house 23 can be used as a storage for storing equipment that is relatively easily soiled, such as chains, parking blocks, towing ropes, camping equipment, and tent anchors.
The materials used include, for example, FRP, iron plates, aluminum plates, synthetic resin materials, and the like.

The towing vehicle C (private car) is a passenger car that the user normally uses on a daily basis, and when in operation, a towing device 17 is attached to the rear of the vehicle to tow the camper trailer 10 of the present invention.

The interior space R is formed to expand the space where the windshield 19, bonnet 20, and headlamp 21 of the existing used car U were installed, and can store a kitchen cabinet, refrigerator, generator, water storage tank, gas cylinder, portable toilet, etc. in the front. In addition, a prefabricated flat sleeping bed 32 (which also serves as an indoor chair) with underfloor storage function, a table, television, AC power outlet, USB port, etc. can be installed, allowing the space to be used for multiple purposes such as cooking, entertainment, and sleeping.

Even if the used car U used in the camper trailer 10 of the present invention is a light vehicle camper specification, it is designed to ensure sufficient interior space R so that an adult can sleep with their legs stretched out.

Other optional equipment that can be installed include a roof carrier 31, a rear carrier, a pop-up roof tent 30, a roof box, an outdoor expansion tent 29, a two-tiered hammock 26, etc.

In addition, the radio, navigation system, anti-theft warning device, sugar lighter, interior lighting, seats (adopted according to user specifications), etc. that are standard equipment on existing Used Car U will be reused.

The air conditioning and heating device that is standard equipment on the towing vehicle C (private car) can send air from the towing vehicle C (private car) to the camper trailer 10 through a ventilation duct hose with a switching function. (The operating function can also be linked with the towing vehicle C (private car) so that it can be operated from an existing used car U.)
In addition, by obtaining AC power from a generator, it is possible to use household or portable heating and cooling devices.

In addition, by mounting a running tire with a suspension at the lower center front of the camper trailer 10 (which can also serve as a running auxiliary tire by using the wide, heavy tire of the connecting towing device 17) to make it a three-wheeled vehicle, it is possible to improve driving and maneuverability while at the same time ensuring stability when parking.

Gasoline tanks can be modified to temporarily store waste water drained from a kitchen sink and allow it to be drained at a convenient location by opening a drain cock on the outside of the tank.

The present invention relates to a camper trailer that utilizes an existing used car, thereby making effective use of the front wheel tire housing and expanding the interior space of the car, while also achieving a low price .

Conventional camper trailers have the operating condition that passengers cannot ride in them while they are driving, but their greatest feature is that the towing vehicle and trailer are connected by a coupler. In other words, if you can detach the towing vehicle and the trailer, you can move freely around your travel destination using only the towing vehicle (your own car). Unlike large self-propelled trailers, camper trailers are maneuverable, so you can easily and casually go sightseeing and shopping at your destination, which greatly increases the freedom and enjoyment of your trip. In addition, the trailer itself can be freely laid out without having to consider seating positions, and the size of the vehicle and interior specifications can also be chosen to reflect a wide range of user preferences, so in recent years, demand for camper trailers as a means of transportation for overnight drive trips has been increasing.

A wide variety of camper vans have been developed to reflect such diverse user preferences. For example, a "Camper Van Box and Camper Van" (Patent Document 1) has been proposed that allows for a large amount of storage space and has excellent heat insulation properties.

However, the proposal for the "Camper Box and Camper" involved fitting a camper box that can greatly expand the storage space to an existing vehicle, which limited the base vehicle to be a luggage vehicle and made it unsuitable for long drives in terms of ride comfort. Furthermore, the camper box itself was custom-made, which resulted in a high vehicle purchase price, and in order to make the camper long enough for an adult to sleep inside, it had to be attached to a larger camper that was one size larger in height.

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, this "camper" proposal involves storing the cabin in the rear cargo area of the camper, which means that the cabin needs to be smaller than the storage space of the camper, and because the camper and cabin are custom-made, the vehicle manufacturing costs and vehicle purchase prices are high.

In addition, a "camper van conversion kit and conversion method using said kit" (Patent Document 3) has been proposed, which allows a person to convert their own car into a camper van and create a living space that is as large as possible.

However, the proposed "camper van conversion kit and conversion method using said kit" has a structure in which the conversion kit is attached to the cargo bed behind the driver's seat of the base vehicle, which means that the cabin itself needs to be smaller than the storage space of the camper van, which means the living space tends to be narrow and it is difficult to ensure sufficient sleeping space. In addition, because the cabin is custom-made, the vehicle production cost and vehicle purchase price are high.

In addition, previous proposals for camper trailers include, for example, a towed vehicle that can provide on-site service at a desired location and can provide a business opportunity for people who are hindered by lack of start-up capital, and a "towing vehicle or a method of providing services to a towing vehicle" that can provide services together with the towed vehicle (Patent Document 4).

However, the proposal for the "towing vehicle or method of providing services to a towing vehicle" was a proposal for the internal layout structure of the towed vehicle, and did not have any particularly significant structural features compared to conventional camper trailers.

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, difficulty in procuring repair parts, long repair periods, and high repair costs. At the same time, compared to existing used cars, they have not been as compact, lightweight, drivable, stylish in exterior design, versatile, robust, waterproof, soundproof, durable, weather-resistant, safe, or convenient.
Furthermore, conventional camper vans and camper trailers have tended to be large, equipped with sleeping beds, sofas, camping equipment, kitchens, toilets, showers, entertainment equipment, etc., and people have been able to stand and walk around inside. As a result, they have been expensive to purchase, difficult to drive, and require parking space, which has been one of the reasons why they have not become widely used.

The applicant has taken the above problems into consideration and envisaged providing a camping trailer that is compact, easy to drive , and cheaper than conventional camping trailers. He has developed a camping trailer that utilizes an existing used car, making effective use of the front wheel tire housing and expanding the interior space while also achieving a low price , which has led to the proposal of the "camping trailer" of the present invention.

The present invention has been made in consideration of the above problems, and its objective is to provide a camper trailer that utilizes an existing used car, thereby making effective use of the front wheel tire housing section, expanding the interior space, and achieving a low price .

The camping trailer of the present invention is a camping trailer that can effectively utilize the front wheel tire housing and expand the interior space of an existing used car by modifying the front part of the main body of the car body. The camping trailer is composed of a car body, a car body frame, rear wheel tires, a shock absorber, a braking device, an indicator light device, a coupling towing device , and a ground fixing device. The front part is opened by removing the windshield part, bonnet part, headlamp part, wiper part, and functions and equipment required for self-propulsion that are attached to the front part of the car body, and the existing used car is installed in the opened front part. A front body cover is formed integrally with the vehicle body within the overall height, width and length of the car, rising vertically from the floor of the body frame to expand the interior space and with a half-dome shaped front ceiling, and the front wheel tire house portions formed on both front sides of the body are fitted with a bottom plate that covers the bottom, hinges, and a tire house cover formed in an approximately semicircular door shape, providing a parts storage space through which items can be directly loaded and unloaded from the outside. The connecting towing device is connected to the front lower center of the body frame, and the ground fixing device is provided on both front lower sides.

The camper trailer of the present invention has the excellent effect of being able to provide a camper trailer at an extremely low price range that has never been seen before, by using used cars such as second-hand cars, immobile cars, scrap cars, discarded cars, and wrecked cars as the base vehicle for the camper trailer.

In addition, the camper trailer of the present invention has the excellent effect of providing a camper trailer with excellent vehicle design performance, such as compactness, light weight, drivability, exterior design, versatility, robustness, waterproofness, soundproofing, durability, weather resistance, safety, convenience, and ease of procurement of repair parts, because the vehicle body uses the exterior design of an existing vehicle manufacturer.

In addition, the camper trailer of the present invention can be easily detached from the towing vehicle for storage, so when parked at home it can be used as a study room for children or a secret base, while when used by adults it can be used as a hobby room (for watching movies or music, reading, playing games, Go, Shogi, Mahjong, painting, playing musical instruments, etc.), a study, a telework room, or a relaxation room, among other excellent advantages.

In addition, the camper trailer of the present invention requires only removing the windshield, bonnet, headlights, and wipers of an existing used car and carrying out some processing during production, which has the excellent effect of significantly reducing production costs, production time, and production processes compared to conventional handmade camper trailers.

The camper trailer of the present invention also has the excellent effect of being able to reuse equipment that is already installed in used cars, such as width lights, turn signals, stop lights, interior lights, license plate lights, hazard lights, batteries, locking keys, automatic door lock devices, door glass lifting devices, anti-theft warning devices, radios, and sugar lighters.

The camper trailer of the present invention also has the excellent effect of providing complete privacy by attaching a shielding film to the window glass of an existing used car.

In addition, the camper trailer of the present invention has the excellent effect of making effective use of vehicle resources that are otherwise scrapped by using used cars with reduced vehicle values, such as second-hand cars, immobile cars, scrapped cars, and wrecked cars, as the base vehicle.

In addition, with the camper trailer of the present invention, the towing vehicle can be used as a normal passenger vehicle for commuting, shopping, etc. in everyday life, and at holiday destinations, the trailer house can be detached and the vehicle can be used as a familiar passenger vehicle, eliminating fatigue while driving and allowing for a wider range of activities at holiday destinations, such as sightseeing and shopping.

In addition, the camper trailer of the present invention has an excellent effect of providing a space suitable for the intended use (storing a bed, sofa, bicycle, motorbike, tent, surfing, paragliding, scuba diving, mountaineering equipment, sports equipment, camping equipment, bedding, etc.) because the interior floor is completely flat and open.

Furthermore, according to the camping trailer of the present invention, the front wheel tire house portions formed on both front sides of the vehicle body are provided with a parts storage compartment which is fitted with a bottom plate that covers the bottom, hinges, and a tire house cover formed in a roughly semicircular door shape, allowing items to be directly loaded and unloaded from the outside. This provides the excellent effect of making it possible to store items which are relatively easily soiled, such as chains, parking blocks, towing ropes, camping equipment, and tent anchors, inside the storage compartment.

In addition, the camping trailer of the present invention has the excellent effect of increasing the purchasing desire of camping users by offering a lineup of trailer houses that are low-priced and feature a variety of car designs from various car manufacturers, making it possible to produce and display inventory for sale in advance.

In addition, the camping trailer of the present invention is essentially sold as a trailer house on its own, which has the excellent effect of allowing the purchaser to purchase a unique, one-of-a-kind camping trailer at a low price that matches their personal tastes and purchasing budget.

In addition, the camping trailer of the present invention has the excellent effect of not taking up much parking space because the trailer house is a relatively compact vehicle, ranging from a light van type to a one-box type, and the towing distance is shorter than that of conventional camping trailers, making it easy to drive even for women or drivers with little driving experience.

Furthermore, while conventional camping trailers were mainly designed for large families with luxurious and large interiors, the camping trailer of the present invention is more targeted at small groups (couples, couples, hobby friends) and young people pursuing hobbies (singles who sleep in their cars) and is compact and equipped with the minimum necessary for auto camping, which has the excellent effect of creating a new demand segment that is different from the family demand segment of conventional camping trailers.

In addition, the camper trailer of the present invention has the excellent effect of providing a diverse and innovative car design that matches the user's tastes and model year by using FRP, steel plate, aluminum plate, synthetic resin material, etc. for the front body cover.

In addition, the camper trailer of the present invention is small, lightweight, easy to use, and can be rented at a low cost, so it can be used in front of local train stations, tourist information centers, rental car offices, etc. to promote a new lodging business, such as a "rental car camping trip" travel plan, and attract new tourists to municipalities that do not have enough accommodation facilities.

In addition, the camping trailer of the present invention has the excellent effect of providing a source of tourism revenue during normal times, and of providing a mobile temporary evacuation shelter in times of emergency disasters, as well as providing accommodation for tourists attending large-scale festivals held by local governments, by placing multiple camping trailers with outdoor tents at a scenic campsite and operating a "camping trailer village" managed by the local government.
