  Bicycles are easy and convenient vehicles, but they are easily left unattended, and neglected bicycles in the vicinity of stations and in downtown areas are a major social problem. For this reason, local governments remove and store abandoned bicycles and dispose of them if the owner does not pick them up within a specified period.

  In this case, the successful bidder buys the bicycle through the bidding system. However, at the present situation where a new bicycle can be obtained at a low price, the profit is low even if it is sold as a used bicycle. It was.

The present invention was created for the purpose of providing a bicycle recycling method that solves the above problems, and includes a rear part of two or more bicycles including a rear wheel and a member that supports the rear wheel, It is disassembled into a front half including the main frame, saddle, steering wheel, and front wheels, and a driving and braking mechanism, and is remodeled into a tricycle having the following configuration (1).
(1) A pair of rear half parts obtained from a disassembled bicycle are attached to the left and right sides of a rectangular carrier member to form a cargo part having wheels on the left and right sides, and the first half obtained from a bicycle disassembled at one end of the above-mentioned carrier part. A tricycle equipped with a driving and braking mechanism obtained from a bicycle disassembled into boarding and front wheel parts by joining the parts together.

  Therefore, according to the present invention, since a new tricycle is manufactured using all the disassembled bicycles, it is possible to realize complete recycling without generating a portion to be discarded, and it is possible to comply with the recycling law 100%. .

  In this case, the bicycle is not disassembled into small parts, but it is easy to disassemble because it is disassembled into the front and rear parts and the drive and braking mechanism, and the existing structure is not significantly changed, so the strength of the original bicycle The design value can be used as it is, and a highly safe tricycle is realized.

  On the other hand, the refurbished tricycle is less likely to fall than a normal bicycle, and even people who cannot ride a normal bicycle can easily ride it, and can also carry a large amount of luggage using a cargo bed. So useful.

  Hereinafter, specific embodiments of the recycling method of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a diagram showing an example of a bicycle to be recycled according to the present invention. This bicycle is a well-known bicycle comprising a rear half A including a rear wheel and a supporting portion thereof, a front half B including a main frame, a saddle, a handle, and a front wheel, and a driving and braking mechanism. The main frame is constructed by joining a standing pipe and a seat post 1, an upper pipe 2 and a lower pipe 3 in a triangular structure, and a front fork foot and a handle post 5 that pivotally support a front wheel 8 are pivotally supported in front, and a seat. A saddle 4 is mounted on the post, and a handle 6 is mounted on the front fork leg and the handle post. The rear wheel 12 is pivotally supported by a support portion composed of a seat stay 10 and a chain stay 11 joined in a V shape, and the front end of the support portion is joined to the standing pipe and the seat post 1 of the main frame. In the figure, reference numeral 20 denotes a chain wheel and a pedal, 21 denotes a chain, and 22 denotes a rear wheel side chain wheel attached to the rear wheel 12. Here, illustration of the speed change mechanism in the brake mechanism and the drive mechanism is omitted.

  FIG. 2 is a diagram showing a process of disassembling the bicycle. Disassembling is performed by first separating the rear half A including the rear wheel and its support part and the front half B including the main frame, saddle, handle and front wheel. Next, the drive mechanism and the brake mechanism are removed as necessary. Here, with respect to the drive mechanism, the chain wheel and the bed 20 and the rear wheel chain wheel are left as they are, and only the chain 21 is removed.

  3 and 4 are views showing an embodiment of a tricycle obtained by the recycling method of the present invention. This tricycle was obtained from a bicycle disassembled at one end of the above-described loading platform portion by attaching a pair of rear half portions A obtained from the bicycle disassembled to the left and right of the rectangular loading platform member X to form a loading platform portion having wheels on the left and right. It is manufactured by joining the front half part B to the boarding and front wheel parts, and further attaching the driving and braking mechanism obtained from the disassembled bicycle to them.

  In this embodiment, the loading platform member X has a structure in which rectangular frames 51, 51 are vertically connected via pillars 52, 52, 52, 52 arranged at four corners, and a reinforcing material is provided in the lower frame 51. The rod-like vertical members 59 and cross members 60 that are also used are bridged to receive a bottom plate (not shown). Between the upper and lower frames 51, 51 of the loading platform member X, the seat stay 10 and the chain stay 11 joined to the V shape in the latter half part A obtained from the disassembled bicycle are joined to the left and right, The wheels 12 and 12 are pivotally supported on the left and right of the loading platform member X to complete the loading platform portion.

  A connecting member 53 projects from the front of the loading platform and is joined to the standing pipe B and the seat post 1 of the front half B obtained from the bicycle whose front end is disassembled, thereby completing the housing of the tricycle.

  On the other hand, intermediate wheels 55 and 57 connected by a shaft 56 are pivotally supported on the lower frame 51 of the loading platform member X. Between the chain wheel and the bedal 20 and the intermediate wheel 55 in the first half portion B obtained from the disassembled bicycle. The chain 21 obtained from the disassembled bicycle is bridged and the chain 58 is bridged between the intermediate wheel 57 and the rear wheel side chain wheel 22 of the rear half portion A obtained from the disassembled bicycle, whereby the driving mechanism of the tricycle is obtained. Complete.

  5 and 6 are diagrams showing different embodiments of the tricycle obtained by the recycling method of the present invention. In this tricycle, two rear parts A obtained from a bicycle disassembled to the left and right of a rectangular carrier member X are attached to form a carrier part having wheels on the left and right, and further obtained from a bicycle disassembled at one end of the above carrier part. It is common to the above-described embodiment in that it is manufactured by joining the front half part B thus obtained to board and front wheel parts, and further to which a driving and braking mechanism obtained from the disassembled bicycle is attached. The positional relationship between the handle and the saddle is different.

  In other words, the saddle 4 of the front half B obtained from the disassembled bicycle is replaced with the front fork foot and the handle post 5 and the handle 6 is alternately replaced with the vertical pipe and the seat post 1 so that the loading platform is placed at the front. It has a tricycle. In this case, since the handle 6 is fixed, in this embodiment, a brake device (not shown) is separately provided on the left and right wheels, and these are alternately operated to change the traveling direction. The remaining configuration of this embodiment is the same as that of the above embodiment, and a detailed description thereof will be omitted.
