Description

A bicycle that moves with the strength of the arms and legs}

The present invention is an invention for a bicycle, and the power generated by rowing is similar to rowing, which is an action of sitting on a bicycle chair, pulling or pushing the handlebar with the hand, and moving the chair back and forth while bending and straightening the legs. A rowing bicycle, which moves the bicycle by transmitting it to the wheels through a chain, and a recumbent bicycle, which moves the power generated by rotating the pedals with your feet while sitting on a chair, is transmitted to the wheels through a chain, all on the same bicycle. It is an invention of a bicycle that can generate and transmit power.

The present invention is a bicycle that moves by generating power by the strength of the arms and legs in the same way as the prior art "a bicycle that moves by generating power by the strength of the arms and legs", but unlike the prior art, the frame part, handle part, and power transmission are used. This is an invention for a bicycle with improved structure and function of the seat, pulley, brake, and pedal parts.

Bicycle powered by arm and leg strength (patent registration number 10-1885468-00-00) Two-wheeled bicycle powered by arm and leg strength (patent registration number 10-1955110-00-00) Bicycle power transmission device powered by arm and leg strength (patent registration number 10-1955118-00-00) Safe bicycle cleat pedal (patent registration number 10-2066795-00-00)

The prior art "Bicycle moved by arm and leg strength (patent registration number 10-1885468-00-00)" and "two-wheeled bicycle moved by arm and leg strength (patent registration number 10-1955110-00-00)" The basic shape of the main material that makes up the frame is H-shaped, and H-beam steel, which is an appropriate standard for bicycle structures, is a material that is not generally distributed or produced, so separate production facilities or processing are required, so production costs are high and material supply is not smooth. , the brake and derailleur strings, which are essential for bicycles, must be fixed to the frame, but in the H-type frame, the strings have no choice but to be fixed to the outside, which is cumbersome and unsightly, so a frame structure that can be hidden within the frame is desirable.

The prior art "Bicycle moved by arm and leg strength (patent registration number 10-1885468-00-00)" and "two-wheeled bicycle moved by arm and leg strength (patent registration number 10-1955110-00-00)" The handle part is a circular pipe that is combined similarly to the legs of a camera tripod, so when you pull the handle and change the length of the handle, friction occurs between the pipes, resulting in power loss. The circular pipe allows you to change the direction of the bicycle by turning the handle. There is the inconvenience of high manufacturing costs because special structures and processing are required to make each circular pipe rotate at the same time.

The prior art "Bicycle moved by arm and leg strength (patent registration number 10-1885468-00-00)" and "two-wheeled bicycle moved by arm and leg strength (patent registration number 10-1955110-00-00)" The power transmission unit has a complex structure and goes through the process of transmitting power through gears, which reduces power transmission efficiency.

The power transmission device of a bicycle (patent registration number 10-1955118-00-00), which is driven by the strength of the arms and legs, has a complex structure for combining and disengaging the device that transmits the power when turning the pedal and the power when pulling the wire. It must be operated manually, and assembling and exchanging parts is difficult.

The prior art "Bicycle moved by arm and leg strength (patent registration number 10-1885468-00-00)" and "two-wheeled bicycle moved by arm and leg strength (patent registration number 10-1955110-00-00)" In order to quickly stop the bicycle in an unexpected situation, the brake lever is installed on the handle of the handle where the hand is located, and the brake lever and the brake are connected through a brake wire. The handle section of which the length changes is used to prevent the act of pulling the handle. As the length of the handle increases and decreases, the brake lever and handle section cannot secure the brake line, and there is a high risk of the brake line breaking as the brake wire repeatedly becomes saggy or tight as the length of the handle changes. Brake strings that are worn or stretched are cumbersome and interfere with the operation of the bicycle.

Prior art "Safe bicycle cleat pedal" (Patent Registration No. 10-2066795-00-00)'s pedal has a structure that makes it difficult to adjust the strength of the coupling force between the cleat clasp and the pedal depending on the characteristics and preferences of the cyclist, and the pedal width and the coupling to the shoe are difficult to control. Since the width of the cleat clasp is similarly large, the cleat clasp is not compatible with or combined with cleat shoes generally distributed on the market, so it is necessary to manufacture cleat shoes that fit, so a cleat pedal that is compatible with shoes distributed on the market is desirable.

In order to improve the frame of the above prior art

The present invention changes the basic main material constituting the frame of the prior art from an H-shaped material to a commonly produced and distributed square pipe material to facilitate the supply and demand of materials, reduce the cost of producing and processing the frame, and reduce the cost of producing and processing the frame. By passing the transmission string through the inside of the square pipe of the frame and hiding it, the aesthetic damage and obstruction caused by the string, which was a previous technology, was eliminated. Unlike the prior invention, the main frame structure was composed of the main frame (40) and the freewheel box (41). ), chainring support (42), and front frame (64). The structure was improved to be assembled by dividing it into parts, so that if any part is damaged, only the damaged part can be easily replaced.

In order to improve the handle part of the above prior art

In order to reduce power loss due to friction between each pipe constituting the handle when changing the overall length of the handle constituting the handle of the previous technology, a handle rod fixing cap 26, which is a part connected and friction between each pipe, The friction force was reduced by inserting a bearing steel ball into the handle bar steel ball holder (27), and the pipe that makes up the handle was changed from a circular pipe to a square pipe to form a handle when turning the handle to change the direction of the bicycle. The structure of the handle has been simplified by allowing the entire pipe to rotate together without any special structure, such as when using a circular pipe, and the handle length can be adjusted as needed, such as when using only pedal power without using handle power. In order to be able to fix the handle at an arbitrary length, the handle fixing pins (29) were used to insert the handle into the holes drilled at regular intervals in each pipe, and the handle length could be fixed according to the preference of the person riding the bicycle.

In order to improve the power transmission part of the prior art

In the prior art, the process of transmitting the power generated by pulling the handle and turning the pulley to the pedal shaft through gear combination is omitted, and the power of the pulley turned by pulling the handle and the power generated by turning the pedal are each responsible for transmitting the power to one axis. By inventing a double freewheel, energy transmission efficiency was improved by omitting the process of transmitting power through gears, and the two types of power generated could be transmitted individually or simultaneously without manipulation.

In order to improve the brakes of the above prior art

In the prior art, the brake is applied by holding the brake lever mounted on the handle handle, but in the present invention, when the handle is lowered, the handle support 30 rotates on its axis to rotate the brake lever 1 to amplify the turning radius, The brake string is coupled to the brake lever (1), and when the angle between the handle and the frame is greater than an angle that can be arbitrarily adjusted, the brake string is not pulled, but the brake lever (1) pulls the brake string only below the set angle, so that the handle handle By eliminating the need for a brake line between the brake lever (1) and the brake lever (1), it was invented to prevent the brake line from breaking or causing an inconvenience due to repeated sagging or tensioning of the brake wire.

In order to improve the cleat pedal of the prior art

In order to make the width of the cleat clasp small enough to be compatible with commonly distributed cleat shoes, the pedal cleat 49 is caught on the pedal cleat 46 in the middle part of the pedal body 44, and the pedal cleat 46 is connected to the pedal cleat 46. The elastic force of the spring 205 allows it to move in close contact with the middle part of the pedal body 44, and the elastic force of the spring 205 can be adjusted by tightening or loosening the bolt 201 in contact with the spring 205. It was invented so that the coupling force between the pedal cleat (49) and the pedal can be arbitrarily adjusted to suit the person's taste.

The chair part 102 changed the structure of the chair support 11 and bearing 200 to fit the newly invented frame part 100, and easily adjusted the angle of the backrest 10 by adjusting the backrest fixing bar 16. It was invented so that it can be adjusted and fixed.

The pulley part 108 was invented to change the direction in which the wire chain 6 and the elastic string 19 move, and to fix the pedal crank 52 by turning the crank fixing pin control wheel 8.

As described above

The frame unit 100 can be manufactured by changing the structure of the main frame using commonly produced and distributed materials to reduce production costs, and the main frame structure is composed of the main frame 40, freewheel box 41, and chain ring. The structure was improved to be assembled by dividing it into the support (42) and the front frame (64), so that if any part is damaged, only the damaged part can be easily replaced, making it convenient for production costs and maintenance.

The handle part 103 is designed to reduce friction by inserting a bearing steel ball into the friction part to reduce the friction between each pipe of the handle when changing the overall length of the handle, and the direction is changed by turning the handle. The structure of the handle was simply improved by changing the pipe that makes up the handle to a square pipe so that the entire pipe that makes up the handle rotates together when handling, and the handle fixing pin (29) allows the handle to be adjusted when necessary according to the person's taste. It was invented so that the handle length can be fixed to the length of

The freewheel unit 101, which transmits power, invented a double freewheel that combines two latches 84, which are responsible for the power of the pulley turned by pulling the handle and the power generated by turning the pedal, to a single latch holder 81. By omitting the process of transmitting power through gears, energy transfer efficiency was improved, and the two types of power generated could be transmitted individually or simultaneously without manipulation.

The brake unit 105 attaches the brake lever (1) to the frame, and when the angle between the handle and the frame is lowered beyond a certain angle that can be set arbitrarily, the brake lever (1) pulls the brake line, and when the angle is greater than the set angle, the brake lever (105) is attached to the frame. By preventing the brake wire from being pulled and omitting the brake wire between the handle handle and the brake lever (1), the brake wire does not become saggy or tight, preventing the brake wire from breaking or creating an inconvenience.

The pedal unit 107 is formed by attaching the pedal cleat 49 to the middle part of the pedal body 44 and the pedal moving member 46 in order to reduce the width of the pedal cleat 49 and make it compatible with cleat shoes available on the market. It has a structure that hangs between them, and the pedal shifter (46) can be moved by the elastic force of the spring (205), and the elastic force of the spring (205) can be used by tightening or loosening the bolt (201) in contact with the spring (205). It was invented so that the coupling force between the pedal cleat (49) and the pedal can be adjusted arbitrarily to suit the person's taste.

The chair part 102 changed the structure of the chair support 11 and bearing 200 to fit the newly invented frame part 100, and easily adjusted the angle of the backrest 10 using the backrest fixing bar 16. It was invented so that it can be adjusted and fixed.

The pulley part 108 was invented to change the direction in which the wire chain 6 and the elastic string 19 move, and to fix the pedal crank 52 by turning the crank fixing pin control wheel 8.

In general, a bicycle generates power by pedaling toward the ground with one foot to rotate the crank, and the other foot is lifted upward by the rotating force of the pedal, which interferes with the power generation.

A cleat pedal is a device that can generate more power by having the pedal and shoe fixed so that one foot steps on the pedal while the other foot lifts the pedal and turns the crank so that both feet generate power together.

In order to separate the pedals and shoes to stop a bicycle equipped with regular bicycle cleat pedals, first turn the rear axle using the front axle of the shoes as an axis to separate the shoes and pedals, then move the shoes to the side and support the feet on the ground. It is separated into a two-stage stopping motion. When an unexpected situation occurs in the bicycle and the bicycle stops suddenly, the person instinctively does not turn the heel of the foot first, but moves the foot to the side and does not separate the foot from the pedal due to the tendency to plant the foot on the ground. There is a problem that often occurs when the shoe is fixed on the pedal and falls as if thrown, resulting in a serious accident.

It switches to the direction where the freewheel unit 101 is located, and continues to turn the freewheel unit 101, while switching to the direction of the pulley 53 of the pulley unit 108 in the freewheel box 41, thereby turning the pulley 53, Continuing to pull the elastic string (19) tied to the wire chain (6), the elastic string (19) rotates the pulley (53) of the pulley portion (108) at the rear of the main frame (40). By changing the direction of 19) to the front of the main frame (40),
If the handle part 103 is pulled, the freewheel part 101 rotates, and if the handle part 103 is not pulled, the wire chain 6 is pulled in the reverse direction by the restoring force of the elastic cord 19, thereby reducing the length of the handle part 103. By allowing the handle portion 103 to be pulled again,
In the end, the chain part 109 turns the rear wheel by the wire chain 6 connected to the power of the freewheel part 101, which rotates by pulling the handle part 103, and the freewheel part 101, which rotates by rotating the pedal, so that the bicycle moves forward. “A bicycle driven by the strength of the arms and legs,” which is characterized by transmitting power to move forward.
