Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foldable bicycle, and more particularly to a foldable bicycle with a carrying case that can be carried in a dedicated box by a user. 2. Description of the Related Art In a folding bicycle, the entire bicycle is compactly folded by bending a body frame.
It is easy to carry. The field of use is further expanded by folding the bicycle in this manner. For example, a folding bicycle can be carried on a train or the like or carried on a trunk of a car, and can be reassembled and freely mounted at a destination. When shopping on a train using such a folding bicycle, there is no need to worry about the parking lot as compared with using a car, which is convenient. In addition, within a few kilometers from the train, it is more efficient in terms of time and cost than buses, taxis and walking. In the case of sightseeing, it is convenient to travel within a few kilometers after arriving at the destination. [0003] When carrying a conventional folding bicycle, it is convenient to have a carrying case for carrying. The carrying case not only enhances the appearance of the folded bicycle but also protects the clothes of other people from getting dirty, and also allows you to carry the bicycle for a short distance, such as when moving from vehicle to vehicle, or hang it on your shoulder. It is intended to carry. Many conventional carrying cases can be folded with a soft material such as cloth or vinyl so that the case becomes compact when the bicycle is used out of the case. In such a conventional carrying case using a soft material, since there is a projection when stored, there is a risk that the projection may hit surrounding people in crowded places such as in a train. Also, when carrying a car, be careful when putting things on a folding bicycle so as not to damage the bicycle, for example,
It is difficult to stack multiple bicycles easily.
In addition, if a hard material is used for the carrying case to solve the above problem, there is a problem that the carrying case becomes an obstacle when using the bicycle. Further, the folding bicycle has a problem that it is difficult or difficult to carry the luggage when using the bicycle due to the small size of the bicycle body because of its original purpose of easy carrying. An object of the present invention is to provide a folding bicycle that solves the above problems. [0004] In order to achieve the above object, the present invention uses a hard material for the carrying case, and when the bicycle is assembled, the carrying case is easily stored on the bicycle carrier for storing luggage. It is characterized by being attached to. In order to make the above-mentioned carrying case easily attachable, it is preferable to provide a mounting bracket dedicated to the carrying case in the structure of the bicycle or to provide a dedicated mounting stand in the structure itself. According to the above construction, when the bicycle is folded and stored in the carrying case, the bicycle body is protected by the hard material, and since there is no protrusion in the stored state, it is safe for the surroundings. When using a bicycle, it is possible to secure a sufficient luggage capacity to be loaded on the bicycle. An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a schematic view of a bicycle according to the present invention. Bolt 3 for fitting with carrying case 2
Is attached. The carrying case 2 is provided with holes for fitting with the bolts 3 so that the carrying case 2 can be placed on a carrier and fixed with nuts 4. The bed 1 is divided into four parts in order to reduce the dimensions when folded. FIG. 2 is a top view showing an example of the carrier 1 divided into four parts.
Shown in The carrier 1 can fold the rear portion 20 of the folding carrier, the right portion 25 of the folding carrier, and the left portion 26 of the folding carrier. FIG. 3 shows a detailed example of the loading platform 1. In the present embodiment, the bolts 3 are directed upward when the divided carrier 1 is expanded. Thus, for example, when using the bicycle with the carrying case 2 removed, the bolts 3 of the carrier 1 do not hinder the loading of the load. The carrying case 2 has a capacity capable of storing a folded bicycle, and has a bed 1 for the bicycle.
The size is stable when fixed to Also, when driving the bicycle by attaching it to the bed 1 of the bicycle,
Packing bed 1 so that luggage can be put in carrying case 2
, The carrying case 2 can be opened. A reflecting plate is attached to the carrying case 2 in this embodiment so as to be safe for use at night. 1 to 5 show a first embodiment. In FIG. 1, a folding bicycle has a first frame 5 as a main frame.
And a second frame 6. A handle post 7 having a handle 24 at the upper end is supported on the second frame 6, and a front wheel 8 is provided below the handle post 7. In the middle of the second frame 6, a connecting shaft and a lock nut,
A first bent portion 12 including a lock lever and the like is provided, and a handle safety lock, a handle stopper, and the like are provided at an intermediate portion of the handle post 7. A rear frame 13 extends rearward from a lower portion of the first frame 5, and the rear frame 13 and an upper portion of the first frame 5 are connected by a rear stay 9. The rear wheel 10 is attached to the rear end of the rear frame 13. A chain 15 is provided between the freewheel of the rear wheel 10 and the drive wheel of the pedal 11.
Is hung. Further, a saddle 17 is attached to the upper part of the first frame 5 via a telescopic frame 16.
The front end of the carrier 1 provided on the upper part of the rear wheel 10 is attached to the rear stay 9. An upper end of an auxiliary stay 18 is fixed to a rear end of the carrier 1, and a lower end of the auxiliary stay 18 is attached to an axle 19 of the rear wheel 10. When the bicycle is folded, it becomes as shown in FIG. 4. By removing the handle 24 and the saddle 17, the bicycle can be stored in the carrying case 2. In the first embodiment, a method of fixing the carrying case 2 with the bolts 3 and the nuts 4 as shown in FIG. In the second embodiment, a spring 21 is used as shown in FIG. Inserting the protrusion 14 of the carrier 1 into the mating hole 23 of the carrying case 2 while pressing the knob 22 of the carrying case 2, and returning the knob 22,
There is an advantage that the same fixing as the fixing by the bolt 3 can be performed, and a fixing time can be shortened. With this mounting structure, the carrying case 2 is not used because the bolt 3 is not used.
Tools such as spanners are not required for attaching and detaching the device. In this case, the time required for attaching and detaching the carrying case 2 is reduced. When carrying a bicycle in a car or carrying it, the nut 4 shown in the first embodiment is removed, the carrying case 2 is removed, and the bicycle is folded and stored in the carrying case 2. In the embodiment, the size of the wheels is 14 inches, so that the length of the carrying case 2 in the longitudinal direction is within 600 mm, and the vehicle is safely driven with the carrying case 2 fixed to the carrier 1. You can choose the dimensions you can. FIG. 7 shows a view of the bicycle according to the present invention as seen from the carrier 1 side.
As shown in FIG. 7, the dirt preventing sheet 28 is mounted in the carrying case 2 to prevent the luggage from being stained when the luggage is put into the carrying case 2 during use as a bicycle. The handle 27 is used for carrying when carrying the bicycle in the carrying case 2. As described above, according to the present invention, by fixing the carrying case 2 of the folding bicycle to the carrier 1, it is possible to increase the load capacity of the luggage, and also to carry and carry the vehicle. There is an excellent effect that loading can be performed safely. [0008]
