[Solution] The three-wheeled randonneur 10 of the present invention employs a means in which a disassembly / assembly type sleeping unit 13 consisting of a canvas sheet 14, seat supports 15, and a sleeping stretcher 16 is freely attachable and detachable on the loading platform frame 12 of the randonneur main body 11.

Description

[Technical field]

[0001] The present invention relates to a three-wheeled randonneur bicycle for touring equipped with a camping facility. [Background technology]

[0002] Conventional proposals for randonneurs equipped with functions for carrying carrier bags for touring and traveling on rough roads include, for example, "Bicycle transport support device and bicycle" (Patent Document 1), which makes it easier to prepare the bicycle for transport.

[0003] However, the structure of the bicycle in the above proposal for the "bicycle transport support device and bicycle" was a bicycle with specifications specialized for touring and bicycle transport, and was not a bicycle equipped with a cargo rack on the rear of the body that could carry a carrier bag or the like to accommodate long-distance bicycle trips.

[0004] In addition, a "three-wheeled bicycle" (Patent Document 2) has been proposed in which cargo bed units with different functions can be freely attached and detached to suit the purpose of use.

[0005] However, the "three-wheeled bicycle" proposal mentioned above was a proposal for a three-wheeled bicycle equipped with a cargo rack on the so-called "mamachari" that is used daily around town, and was not a bicycle equipped with a cargo rack on the rear of the body that could carry a carrier bag or the like for long-distance bicycle trips.

[0006] In addition, a "body cover for motorcycles" (Patent Document 3) has been proposed that prevents motorcycles from being broken or scratched when transporting them and allows more motorcycles to be transported.

[0007] However, the above proposal for a "body cover for motorcycles" was a proposal for a body cover for motorcycles that was specialized for use when transporting motorcycles, and its function was merely to cover the entire motorcycle while it was being transported, and it was not a proposal for a body cover that had the function of allowing a folded bicycle to be brought into or transported in a moving vehicle.

[0008] The applicant, in consideration of the problems with touring bicycles mentioned above, envisaged providing a touring bicycle that was compact, inexpensive to manufacture, and also allowed for overnight stays in the vehicle. With this in mind, he developed a three-wheeled randonneur touring bicycle with overnight stay capabilities, which led to the proposal of the "three-wheeled randonneur" of the present invention.

[0010] The present invention has been made in consideration of the above problems, and an object of the present invention is to provide a three-wheeled randonneur touring bicycle equipped with a bicycle camping function. [Means for solving the problem]

[0011] The three-wheeled randonneur in the present invention is It consists of three wheels: one in the front and two in the rear. A disassembly / assembly type sleeping unit consisting of a canvas sheet, seat supports, and a sleeping stretcher is detachably mounted on the loading platform frame of the randonneur main body.

[0012] In addition, the three-wheeled randonneur in this invention divides the randonneur body into at least three parts: a front tire section, an intermediate tube section, and a rear tire section. A chain wheel cover with casters is attached to the chain wheel mounted inside the rear tire section, and the entire randonneur body is covered with a portable cycle cover to enable transportation by train.

[0013] The three-wheeled randonneur in accordance with the present invention employs a means for providing an extension function to the rising portion of the seat support pillar. Effect of the Invention

[0014] The three-wheeled randonneur of the present invention has a disassembly and assembly type sleeping unit that can be easily attached and detached to the randonneur body, which has the excellent effect of allowing you to sleep in the vehicle directly on the randonneur body without having to set up a camping tent directly on the ground.

[0015] In addition, with the three-wheeled randonneur of the present invention, because the bicycle itself has three wheels, carrier bags and other items necessary for long-distance travel can be loaded onto the loading frame of the randonneur body, which has the excellent effect of allowing the bicycle to be ridden easily and stably without having to balance the load while riding, and allowing a large amount of bicycle travel items to be loaded.

[0016] Furthermore, with the three-wheeled randonneur bicycle of the present invention, the bicycle itself has a foldable body, which allows it to be disassembled and stored compactly when traveling, and furthermore allows it to be easily transported on trains and in public facilities, providing the excellent advantage of being easy to transport.

[0017] In addition, with the three-wheeled randonneur of the present invention, the raised portions of the seat posts are designed to slide freely, so that when riding the sleeping unit can be contained within the external dimensions of the randonneur main body, giving the bike a smart appearance, and when sleeping the raised portions of the seat posts can be extended to provide a larger sleeping space, which is an excellent effect.

[0018] In addition, the three-wheeled randonneur of the present invention has the excellent effect of being able to be used in everyday life for shopping or to pick up and drop off children by equipping the randonneur body with a shopping basket and child seats on the loading platform frame.
