Abstract

<P>PROBLEM TO BE SOLVED: To reduce a traveling load of a bicycle easily and conveniently used by people, in accordance with the rules of actions of people and in harmony with nature, and used as a healthy traveling tool. <P>SOLUTION: The weights of a front carrier basket and a cargo therein, a bicycle, and a rider are divided into two parts with respect to a pivot near a handle shaft 1 to derive the feeling of the reduced rotating load of a pedal. Since the structure of a front wheel fork 2 contains a forward self-rotating element, the structure is formed so that the diameters of the front and rear wheels are different from each other and a frame 3 is formed in a loop structure, and the column of the rear wheel axle is formed in the structure of a fork 11 so as to increase a running performance. <P>COPYRIGHT: (C)2003,JPO

Description

Detailed Description of the Invention

[0001]

[Industrial application] On the walls of the stairs of the Bicycle Hall in Toranomon, Tokyo, there are some powerful foreign paintings depicting old-fashioned machines, thoughts about bicycles, and attachment. Bicycles are the most familiar and accessible tools that make sense of human behavior, so I think there is a great desire to reduce their travel. In addition, today's daily crude oil consumption in Japan is said to be over 500,000 tons. (Techno Detectives / Tanker Special Feature, Captain's Talk) To prepare for that, it is important to reduce the amount of bicycle travel, aiming to expand the range of activities on your own. Moreover, we cannot stop believing that the richness of the economy is the richness of the hearts of the people who compose it. The present invention pursues such a proposition from the viewpoint of carrying luggage.

[0002]

2. Description of the Related Art The 1997 Utility Model Registration No. 3040212, which aims to reduce the traveling of a bicycle at the mounting position of a luggage basket, is an application for an elementary student. The technical evaluation for it was 2, and it was difficult to recognize the progress too much from the previous application. As for the previous application, reference 1 is Japanese Patent Application No. Sho 49-00423, No. Shokai 50-95.
No. 745, Microfilm Document 2, Japanese Utility Model Application No. 61-90008, Japanese Utility Model Application No. 62-20
No. 1184, Microfilm Document 3, Registered Utility Model No. 58813. I have made a prototype car based on this, as shown in the attached photo, and have been trying to move in the direction of 10 km for commuting, shopping etc. for the past 23 years, but it is interesting that the steering direction is slightly behind and the direction of travel is facing Anyway, I don't feel any other inconvenience. Also, the reduction of bicycle travel depends on the material,
It can be seen in the city that electric power was used to drive on slopes and that gears were installed.

[0003]

[Problems to be Solved by the Invention] There is no other convenient tool that is more convenient, familiar, and easier to come and go as it comes and goes by bicycle. I think that the lack of "" can reduce the life of people. We believe that the richness of the economy is the richness of the hearts of the people who compose it, and in a capitalist society, value must be produced, and the appropriation of that product was seen. I don't think there is such a good story of Awaji with wet hands today. I don't think there is any forerunner. The first step in the production of value is to carry goods, and we must take it seriously that if the activity is high, the profit of the produced goods will be small. I believe that the thoroughness of this and the accumulation of it will be the source of fostering the richness of people and society. We pray for the further development of convenient, convenient, and easy-to-go tools that are environmentally friendly, transfer resources to future generations, and maintain and promote human health.

[Means for solving problems] 3 of Annex of National Diet Library
The Bicycle Practical Handbook, 5th Edition, published by the Bicycle Industry Promotion Association, is located in the Science and Technology Materials Room on the first floor. In addition, a prototype vehicle according to the above-mentioned utility model registration No. 3040212 by I was attached to a 27-inch vehicle as shown in the attached photo.
First of all, with three or four square talcs, sandwich the two frame pipes above the three frame pipes assembled in the handle bearing cylinder part from the left and right in a substantially horizontal direction, and then crotch the frame pipe and further in front of the handle container. And, on the frame that was welded diagonally and straightly here, a hole for 3 minutes was drilled at a total of three places that hit the outside, and the outer diameter of the receiving pipe and the thickness of the left and right talcs. Total of 9.5c
m and a screw allowance of 1 cm and 11.5 cm, respectively, for 3 minutes, and a 3 cm square washer was applied and tightened with a nut. Move the left and right talcs further forward and downward so that they do not interfere with the operation of the steering wheel, and 35c from the receiving tube.
While ensuring m extension and horizontalness on the left and right, a commercially available vertical, horizontal, and Takasa gold knitting baskets of 40, 30, and 23 cm each were tightened with bolts and screws. In addition, the rearmost bolt of the three 3-minute bolts bite the additional start-up talquis to the left and right, so that it started up parallel to the handle shaft up to the top of the handle shaft. The ball bearing was fitted, and the outer ring was raised and sandwiched between talcs and fixed to a plate having a width of 9.5 cm. Therefore, this luggage basket is not linked to the operation of the handle,
It was firmly attached at a distance of m. Next, the structure of the front wheel fork is a special program of the bicycle fork by the techno detective group, which was broadcast on Saturday, Channel 12 from 6:00 pm on the bicycle practical handbook (aired about a year ago). According to the above, it is said that it will contribute to the prevention of falls and the assistance of some forward rotation, and the loop frame is used for light bicycles,
It is said to be located in the middle of diamond frame practical vehicles and sports type vehicles in terms of its lightness. Here, I thought that the loop and double-loop frame were variations of this fork. For example, if a roller is attached to the end of a frame with different pine needle-shaped loops, and if a downward force (weight) is applied vertically at the intersection, it will try to open to the one with more loops. Isn't it? I think that it will be more of an impetus for elementary school students. Rolls on chair legs where the vertical and horizontal cores do not intersect, and handlebar shafts on motorcycles that have fallen asleep are considered to be of this type.
The 22-inch bicycle frame attached to my application for registration of a utility model is a lunar loop frame with an upper chord that opens on top of one, but the coasting extends beyond the riding sensation. I thought that the technique could be done because the fork was deformed. When the front wheels are sunk, the luggage basket is cut and the steering wheel is operated to stick out and the luggage is loaded, and the loop that opens the frame in the shape of a moon in the upper string is taken, the traveling lightness is likely to extend.

[0005]

【Action】 Now, if you separate the front wheel from the frame, put the front wheel on the ground, set the handle vertically, and apply the force (weight) directly below, the force just below If it is (weight), the front wheels try to move up and roll up. However, if this force (weight) and the propulsive force from directly behind the fork are applied, it will try to roll forward. In other words, the structure of the fork is naturally equipped with the force to move forward depending on the weight and weight of the person, and it is considered that the pedaling force may increase or decrease depending on the structure. In addition, it is possible that this structure (apart from steering wheel rotation) can also be applied to the rear wheels, and if so, the lightness will be further increased. Also motorcycles,
In automobiles, a shock absorber is attached to the mounting part of the wheel to absorb the impact of the road surface, but even if this fork structure has a structure that exerts elasticity, it will also reduce the propulsion force. I think that the. By the way, the attachment method of this basket is more than this attachment method of the utility model registration No. 3040212 of Osamu.
The position of the fulcrum of the rider and the bicycle is the position where it is crimped to the ball bearing attached to the handle shaft (the two front mounting bolts of the luggage carrier are slightly movable).
More commonly known as "ditch," which is more stable and is used for cargo handling work.
You can attach a basket that closely adheres to your frame, and since the luggage does not move much, you can carry a lot of it. Even if the diameter of the front wheel is made smaller than the diameter of the rear wheel, if you handle the vehicle by extending the handle shaft, there will be no hindrance to running, and if you can carry your luggage lightly, you will be unfamiliar. The problem will be resolved. I think it will be a little easier to climb uphill because the basket is lowered to the front. Next, the loop or double loop structure is adopted for light cars and children's cars, but if this structure is the mainstream in the United States,
As mentioned in the Bicycle Handbook, 22
An inch loop bike feels like it falls well. This structure has something that is exactly similar to the structure of the fork, and if it falls forward, it seems that the feeling of rolling further increases.

[0006]

[Embodiment] The fulcrum of the weight of the luggage and the riding bicycle should be near the top of the handle shaft, so that the luggage basket should be lowered forward,
By making the diameter of the front wheel smaller than the diameter of the rear wheel, the structure of the loop from the handle shaft to the saddle shaft is likely to be lowered front, and as a structure that inevitably travels, the structure of the fork is further

As shown in [Fig.2], the lightness is increased by exerting it on the rear wheels as well, but if it is biased too much to the front load, the rear wheels will have less force to reach the ground and the propulsion force will be reduced. There is a lot of fear that it will decrease, so it is important to be careful not to overload.

[0007]

[Advantages of the Invention] By setting the mounting position of the luggage basket here, the pedal force with the weight obtained by subtracting the weight of the luggage and the luggage basket from the weight of the rider and the bicycle is sufficient. It does not lead to things. On the other hand, the frame structure in which the bicycle is sunk in the front, the loop structure, and if possible the fork structure of the rear wheel enhances the running performance of the bicycle, which is the coasting test referred to in the "Practical Manual for Bicycles". It is intended to increase the mileage due to. These measures to increase the driving comfort are a matter of comparison. In addition, since bicycles are easy and familiar tools, they are probably delicate ones. Therefore, daily maintenance such as lubrication (which also applies grease to the bearing) and screw tightening is essential. Even if this work is done, the rider's own driving is essential, so it is much more efficient than walking, but far less than a fuel running tool. However, the actions and movements as a person are very pleasant, and I am convinced.
