Left and right side plates 1 in storage case 10
A rear wheel 22, a brake 23, a sprocket wheel 24, and the like are rotatably supported via an axle 25 between the rearward sides of the wheels 1 and 12. The transmission system of the rear wheel 22 has one end of a pair of rear wheel stays 26 attached to the left and right ends of the axle 25, and the other end attached to a cylindrical support member 27 so as to be rotatable by the cylindrical support member 27. Sprocket 29 of pedal shaft 28 supported and sprocket wheel 2 of rear wheel 22
4, a chain 30 is suspended, a pedal arm 31 integrally attached to left and right ends of a pedal shaft 28, and a pedal 32 foldably connected to the pedal arm 31.
, A pedal shaft 28 is driven, and its rotational force is applied to the rear wheel 2.
2 is transmitted.

A pair of brackets 33 are provided on both ends of the upper surface of the cylindrical support member 27 by welding or the like, and a horizontal shaft 34 fixed between the brackets 33, 33 has a front wheel stay 35.
Are connected so as to be rotatable in the vertical direction. The front wheel stay 35 has a substantially T-shape, and a front wheel 38 has an axle 39 between the lower front forks 37 of the branch stay portion 36.
And is rotatably mounted via a branch stay portion 36.
A handle shaft 40 is connected to the upper end of the handle shaft 40 so that the handle shaft 40 can be turned upside down. For example, as shown in FIG. 9, an opening 43 is formed on the upper end surface of the stay portion 36 at the center in the radial direction as shown in FIG. A pair of support portions 42 having a symmetrical shape and having a screw portion 44 and a shaft hole 45 are erected, and a lower end block portion 46 of a handle shaft 40 is fitted into an opening 43 of the support portion 42, and the shaft A screw 48 is vertically rotatably supported by a shaft 48 inserted into a fitting hole between the hole 47 and the bearing shaft hole 45, and a screw portion 50 of a tightening nut 49 loosely inserted into the handle shaft 40 is supported by the bearing 42. The handle shaft 40 and the branch stay portion 36 are linearly integrated with each other by being screwed into the screw portion 44, the tightening nut 49 is loosened, and the hand shaft 40 is folded rearward with the shaft 48 as a support. Is to be . This raising and lowering structure is the same in the relationship between the handle shaft 40 and the left and right handles 41, and the description thereof is omitted.

As shown in FIG. 1, when the front wheel 38 is out of the storage case 10 in a use state,
To support the front wheel stay 35, sprocket 29, etc.
A body stay 51 is rotatably attached to the front wheel stay 35. More specifically, the body stay 51
As shown in FIG. 10, a mounting portion 52 that is branched into two parts at the lower part of the bracket 3
A substantially U-shaped locking portion 53 at the upper end is rotatably supported on a horizontal shaft 34 between the third and third shafts 33, and a locking edge provided at the upper edge of the front plate opening 18 in the storage case 10. The member 54 is locked, and the locking support state is set screw 55
When unnecessary, the setscrew 55 is removed, the storage case 10 is disengaged from the locking edge member 54 through a slightly upward lifting, and the horizontal shaft 34 is supported. It is pivoted downward as a body and its locking portion 5
3 is supported by an upper end receiving portion 57 of a support rod 56 erected on one rear wheel stay 26, and the whole including the front wheel 38 and the like is folded and stored in the storage case 10. As shown in FIGS. 5 and 1, an auxiliary transport vehicle 59 is rotatably mounted on a notch 58 of the bottom plate 16 of the storage case 10 via a bracket 60 and an axle 61. ing.

In use, as shown in FIG. 1, the front wheel 38, the handle 41, etc. are taken out of the storage case 10, and the locking portion 53 of the body stay 51 is locked in the storage case 10. The user straddles the storage case 10 while being locked by the edge member 54, places the buttocks on the saddle portion 20, and runs the pedals 32.

When not in use, as shown in FIG. 2, members such as the handle 41, the handle shaft 40, and the front wheel 38 are folded and stored in the storage case 10. More specifically, the left and right handles 41 are rotated downward and folded with respect to the handle shaft 40, and
Is loosened by rotating the fastening nut 49 and pivoted downward with the shaft 48 as a support, and is folded with respect to the front wheel stay 35, and the body stay 51 is engaged with the opening portion of the storage case 10 by the locking portion 53. The engagement with the retaining member 54 is released, and the pivot member 34 is pivoted rearward with the horizontal shaft 34 as a support, and is tilted down. The engagement portion 53 is engaged with the receiving portion 57 of the support rod 56 to be supported. The pedal 32 is folded,
The front wheel stay 35 is rotated rearward with the horizontal shaft 34 as a support together with the front wheel 38, and accordingly, the sprocket 29 is rotated rearward with the rear wheel stay 26 and the axle 25 as a support. It is stored in the storage case 10.

[0014]

[Effects of the Invention] According to the present invention, however, since the storage case itself is a part of the bicycle body, the folding storage in the storage case and the assembling of the drawer from the storage case are simple and quick. Not only can the body stay be used,
The stop is locked to the locking edge member of the storage case,
It is used by retaining the locked state with the set screw
The sprocket between the front and rear wheels
And the vehicle can be run lightly.
When not in use, remove the set screw and remove the hand.
Of the body stay where the front wheels, etc.
The substantially U-shaped locking portion is locked and supported by the upper end receiving portion of the support rod.
It is stored neatly, so it is stored neatly and there is no protruding, the whole is compact, and stacking etc. is possible, so there is little storage space, and the rear wheel and auxiliary are pushed by pushing the transport Because it can be run through the rotation of the car, it is simple and supports the body stay.
The folded and stored state is maintained well by the action of the holding rod.
Therefore, the vehicle can be run without rattling, and furthermore, it looks like a suitcase for overseas travel when transported, and has good appearance and excellent fashionability.

Further, since the storage case is made of a tough hard synthetic resin, it is light in weight as a whole and is easy to carry, and the storage case is folded and stored in the storage case for the rear wheel, the front wheel, and the auxiliary vehicle. Since the rest is completely inside the storage case except for the grounding part, rainwater etc. do not directly hit the internal bicycle during storage etc., so it does not rust or get dirty and has excellent durability etc. .
