Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a bicycle equipped with a luggage compartment for storing and transporting goods.

As schematically shown in Fig. 5, bicycles with rocket- or torpedo-shaped luggage compartments 63 and 64 attached above the front wheels 61 and rear wheels 62 for mobile sales of sweets have been available in central Tokyo since around March of this year. You can watch it now 5 and also ``Nikkei Business J''

It has also been introduced with photos in issue 8 and other publications.

As you can see from the drawing, a bicycle with this luggage compartment has a high center of gravity, which not only has the drawback of becoming extremely unstable and prone to falling depending on the weight of the luggage, but also has the disadvantage that the luggage compartment has a large cross section. Since they are circular or oval, depending on the shape of the baggage, there may be unnecessary air gaps and the amount of cargo that can be carried may be small.In addition, each baggage compartment has a single-chamber structure with a fairly large capacity, so it is difficult to store items that require cooling. When handling bicycles, there is the disadvantage that a cooling effect cannot be obtained unless a large amount of dry ice is used.Furthermore, they must be fixed to the bicycle frame using arms or metal fittings, which increases the weight and makes assembly and disassembly difficult. This has the problem of being troublesome.Furthermore, there is also the problem of not being able to drive at night because headlights cannot be used due to the front luggage compartment.

The present invention provides a bicycle for carrying luggage, which has a low center of gravity (and a luggage compartment is attached to the frame with a simple structure), and has a small number of front wheels and rear wheels (both sides of either wheel are In order to solve the above-mentioned problems, luggage compartments are disposed in the frame, and these luggage compartments are removably fixed to the frame by fasteners.

Example Examples of the present invention will be described based on the drawings.

In the present invention, a commercially available bicycle or a slightly modified bicycle is used, and a loading platform 3.4 is provided above the front wheels 1 and the rear wheels 2. 2 In the present invention, the loading platform 3,
4. Front fork 6, front stay 7, rear fork 8. Rear stay 9° upper pipe 10. Lower pipe 1). The frame 5 is defined as including the vertical pipe 12. In addition, han, dollar 13,
Saddle 14. Pedal 15. It is the same as the conventional vehicle in that it includes a headlamp 16 and a brake (not shown).

Bolt rods 17a, 18a, 19a, 20m are welded upward on the front and rear loading platforms 3.4, respectively, on the front, rear, left and right sides.
After 1 fork 8. 21m bolts on each rear stay 9
, 22a, 23a, 24m are implanted outwardly by welding, and bolt rods 17a, 18a, 21a, 22a are arranged above and to the sides of the front wheel 1.
The bolt rods 19m, 20m, 23 cooperate with the nuts 17b, 18b, 21b, 22b to form the front fixing device 25, and are arranged above and on the sides of the rear wheel 2.
m, 24m are nut 19b, 20b.

It cooperates with 23b and 24b to form a rear fastener 26.

Luggage compartments 27A and 27B located on both sides of the front wheel l
has a symmetrical shape and is made into a rectangular shape, but at the tip, the top wall 28j+5 and the bottom wall 29 are curved and continue smoothly with each other at the tip, and the outer wall 30 is curved toward the inner wall 31. It is formed into a streamlined shape with a top wall 28
The opening 032 provided in the opening 032 is closed by a hinge-type lid 33, and the entire structure is sealed. The inner wall 31 has a rear portion recessed outward, has mounting holes 34 at the front and rear thereof, and has a connecting hole 35 at the tip, and also has a connecting hole 35 at the tip.
8 has mounting grooves 36 at the front and back of the part that overhangs the above-mentioned part.
The bolt rods 21 m + 22 m projecting outwardly pass through the mounting hole 34, and the bolt rods 17a, 18a projecting upward pass through the mounting groove 36, respectively, and nuts 21b, 22b are tightened therein. A bolt rod 37a fixed to the frame 5 by 17b and 18b and further passed through the connecting hole 35, and a nut tightened into the bolt rod 37
They are connected and fixed to each other by a connector 38 which also serves as the connector 38.

Luggage compartments 39A and 39B located on both sides of the rear wheel 20
is also symmetrical in shape and made into a rectangle, but at the rear end, the m wall 40 and the bottom wall 41 are curved and are formed into a streamlined shape that smoothly continues with each other at the rear end, and the top wall The opening 044 provided in the housing 40 is closed by a hinged lid 45, resulting in an airtight structure as a whole. The outer wall 42 and the inner wall 43 are parallel to each other, but the front part of the inner wall 43 is curved outward, and has mounting holes 46 at the front and rear thereof, and a connecting hole 47 at the rear end. It also has mounting grooves 48 at the front and rear of the portion of the top wall 40 that extends above the bulge portion.

399 is a bolt rod 1 in which bolt rods 23m and 24m project outward and pass through the mounting holes 46, respectively, and project upward.
Nuts 23b, 24b, 19b with 9a and 20m passing through the mounting groove 48 and tightened respectively.

20b is internally defined in the frame 5, and furthermore, the connecting hole 47
They are connected and fixed to each other by a connecting tool 50 consisting of a bolt rod 49a (M) passed through and a nut (49b) tightened therein.

That is, two luggage compartments 27^, 27B and 39 in the front and rear.
In A, 391), the top walls 28, 40 rest on the loading platform 3.4 and are fixed, and the inner wall 31.43 is fixed to the front and rear forks and stays on the side of the front wheel 1 and the rear wheel 2, and is therefore attached to the frame 5. It is installed in a cantilevered state. Also, Natsu)
Luggage compartments 27A, 27B, 39A by loosening and removing 17b...24b.

39B can be removed.

The fasteners 25 and 26 are either made of screws and provided with screw holes in the frame 5 to fasten the luggage compartments 27A...39B, or they can be attached and removed by rotation or snap action without using screws. These can be provided not only at the locations shown in the above embodiments but also at any arbitrary locations. Also, rear luggage compartments 39^, 39B
A reflective mirror 51'7 is provided at the rear end, and a luggage compartment 27A.
...7 advertisements are displayed on the front of the 399.

Or a board displaying advertisements, etc. between luggage compartments 27^ and 27B, 39A and 39°0 on both sides! You can get sandwiched beans.

Also. It goes without saying that the luggage compartments 27A...399 may be attached only to either the front or the rear.

According to the present invention, since the luggage storage device is installed on both sides of the wheel, the luggage is placed at a lower position than the loading platform, and the center of gravity is low (so that even heavy luggage can be stored. Not only does it not cause the problem of losing stability and being prone to tipping over, but even if the - luggage compartment is made to have a smaller capacity than the conventional one, the overall capacity is increased because it is equipped with two or four luggage compartments. Along with.

When handling products that require cooling, a small amount of dry ice can provide a sufficient cooling effect. In addition, since the frame of the cargo platform, fork, stay, etc. is mounted in a cantilevered state using fixing tools, there is almost no need for arms or metal fittings for fixing, and not only does it not add unnecessary weight, but it is also easy to assemble and remove. It is easy to use, and if you remove the luggage compartment, you can use it as a regular bicycle.

In addition, when the baggage compartment has a square cross section and is installed without protruding above the loading platform as in the example, it is possible to store the baggage without creating unnecessary space and increase the number of loading spaces. This is expected to have effects such as being able to drive at night since it does not interfere with the light.
