Description

Paddle Bike {BICYCLE OF SINGLE WHEEL}

The present invention relates to a paddle bicycle, and more particularly, to a saddle, a pedal, a handle, and the like coupled to the side or the inside based on a structure composed of one large wheel, in order to pursue the stability of the user and to easily operate the paddle bicycle. will be.

There are various types and structures of bicycles, and road bicycles, mountain bikes, and fitness bicycles exist according to their use, or various types of bicycles are used according to the number of wheels.

Among these, the outer ring bicycle is driven by pressing the pedal by supporting the center with a single wheel, and thus the use range is limited to the case of being used as a circus or a special use rather than a general bicycle.

 The reason for this is that it is difficult to use the bicycle while mounting the saddle on the upper part of the unicycle, which has a general size, and the user rides on it.

However, if you expand the size of the wheel to combine the basic components such as saddles and pedals on the inside or side of the wheel, the user will be able to ride the bike while holding the center of gravity easily. Bicycles based on this concept are disclosed in Korean Utility Model No. 376618.

According to the above technology, the support frame is fixed to the drive frame driven by the steering wheel, pedal, saddle and chain and the support frame is fixed to the inner circle of the wheel, the inner gear is formed on the center of the inner surface on the inner arc of the wheel And a binding groove is formed at both sides, and the support frame is bent at a circular inner curvature of the wheels, and both lower sides are provided with a plurality of binding plates coupled with rollers, which are coupled to the binding grooves, and two driven sprockets are disposed at one side. One of which is engaged with the inner gear and the other is connected by a chain with a drive sprocket coupled to the pedal shaft.

However, according to the above technology, since the position where the pedal is formed is the inner part of the wheel, when the user tries to grasp the center of gravity while driving, the user's foot does not touch the ground and loses its center, there is a risk of falling. In order to prevent this, if the length of the support frame supporting the pedal and the pedal shaft is shortened in the above technique, the height of the saddle is correspondingly lowered. In this case, the overall center of gravity is tilted too downward, which causes a problem in stability.

In addition, since the support frame is configured only at the lower part of the wheels, and the upper wheels are exposed to the outside, as the wheels rotate, the upper wheels are swayed to make smooth driving, and the wheels themselves have a thin structure. On the other hand, the diameter of the bicycle is much larger than that of a general bicycle, and there is a disadvantage in that it is structurally vulnerable to external shocks because it does not have other components to reinforce it. Because it is composed of strings, the structure is far away, and the chain portion connecting the lengthens. However, if the chain is lengthened, there is a problem that the chain is often separated from the sprocket during the rotation of the pedal.

If the cover is to overcome the problem by covering the sprocket or chain part with the cover, the cover crosses the length of one side string of the upper and lower surfaces of the structure, that is, the distance between the sprockets. It is not enough to prevent the chain from falling off. In addition, the configuration of the handle also has a problem in that the center of gravity is inclined to one side when the user is sitting in the saddle, so that the user himself difficult to balance the main handle.

The present invention has been made in order to overcome the above problems, the purpose is to provide a structure of a paddle bicycle having a handle, a pedal, a saddle in the circular shape of the wheel, but more considering the user's stability in an ergonomic design.

Another object of the present invention is to provide a paddle bicycle that can deliver the driving force to the wheel faithfully while shortening the length of the chain as well as having a structure for driving the external wheel to the inside due to the driving force transmitted from the pedal. To provide.

Another object of the present invention is to provide a plurality of connecting frames for reinforcing the structure by connecting them to a circular frame having a different inner and outer diameters, and having a fixed frame therein in a circle along the circumference of the frame of the inner wheel to connect each other It is to reinforce the stability of the wheel itself.

In order to achieve the above object, the outer ring bicycle according to the present invention has a diameter smaller than the outer rim 120 and the outer rim 120 in which the tire 110 is mounted on the outside and makes contact with the driving wheel 210 on the inner side.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings are not drawn to scale, and like reference numerals in each of the drawings refer to like elements.

The paddle bicycle according to the present invention has a wheel 100 having a diameter larger than that of a general bicycle wheel, and a fixed frame 150 connected to the inside of the wheel 100, a saddle 190 provided inside the fixed frame 150, and wheels. It consists of a driving means for transmitting a driving force to the 100 and a braking means for transmitting a braking force to the wheel (100).

Looking first at the structure of the wheel 100 of the outer ring bicycle according to the present invention, it consists of a double rim structure, the outer rim 120 is a part that is driven through frictional contact with the road surface tire 110 is mounted on the outside The inner rim 130 has a semicircular groove 135 which receives the driving force through the rotation of the driving means to be described later. The inner and outer rims 120 and 130 are connected to each other by a plurality of connection frames (spokes) 140, such as a grate, which prevents the wheel from being easily bent during external impact or driving, thereby making the wheel 100 safer. It can guarantee the structure of

In addition, a space in which the connection frame 140 is formed between the inner and outer rims 120 and 130 of the wheel 100 may be provided with an advertisement means printed with a separate advertisement word or picture. The advertising means is made of a material such as cloth or cardboard has a doughnut shape formed corresponding to the space between the inner and outer rims (120, 130), in order to provide the advertising means, both ends of the connecting frame 140, That is, a plurality of orifices 145 are formed at a portion where the connecting frame 140 and the inner and outer rims 120 and 130 are in contact with each other, thereby enabling connection with an advertising means equipped with a connecting means such as a string.

The semi-circular groove 135 in the inner rim 130 of the wheel 100 may be in contact with the driving wheel 210 of the driving means to receive the rotational force of the driving wheel 210, and this driving principle will be described later. Let's do it.

The wheel 100 has a slightly smaller diameter than the inner rim 130 on the inner side of the inner rim 130 and is connected to the fixed frame 150 having a circular shape which is dually formed on the left and right sides.

The connection structure of the wheel 100 and the fixed frame 150 is located in the middle portion of the frame consisting of a double of the fixed frame 150, the inner rim 130 of the wheel 100 is located and the connection of both the fixed frame 150 A plurality of rollers 160 which are axially fixed to the fixed frame 150 are axially coupled to a plurality of, preferably radially equally spaced along the outer circumferential surface of the fixed frame 150 at an equal interval in the upper and lower rim 130 It can be achieved by rotating on the semi-circular groove (135) of). The semi-circular groove 135 may be further formed with a rubber member having a suitable texture so that this portion is not too smooth.

One side of the fixed frame 150, specifically, the user's hand can be reached is provided with a handle 310 that can hold both hands and the outside of the handle 310, that is, the direction of the wheel 100 The handle bar 330 which is attached to the fixed frame 150 and extends vertically in the direction of forming the handle 310 is connected from the handle 310, and the handle 310 has a braking lever 320. The braking wire attached and connected to the brake lever 320 extends over the side surface of the inner rim 130 of the wheel 100 and is connected to the rim brake 340 installed at the end of the handle bar 330. The rim brake 340 contacts the side surface of the inner rim 130 and brakes the rotating wheel 100 according to the user's manipulation of the brake lever 320.

Since the shape of the rim brake 340 is relatively small compared to the diameter of the inner rim 130, the friction of the inner rim 130 of the wheel 100 can be increased more smoothly by the operation of the rim brake 340. I need a solution. To this end, a plurality of braking holes 136 are formed on the bilateral outer surfaces of the inner rim 130 to form a streamlined connection by smoothing each process, and the braking holes 136 are rim brakes 340. ). For example, when the rim brake 340 is perpendicularly contacted with the inner rim 130 in the vertical direction, the elliptical braking hole 136 is formed in the vertical direction corresponding to the shape. When the round protrusion 345 is formed at the end of the rim brake 340, a correspondingly rounded braking hole 136 may be provided. Thus, the rim brake 340 having the protrusion 345 is a replaceable consumable and is preferably made of a synthetic resin material such as rubber.

In addition, although not shown in the drawing, the left and right braking levers 320 of the handle 310 may be connected to the rim brakes 340 formed in two parts, respectively, as in a known bicycle, to increase the effect of braking. For example, when the left brake lever 320 is pressed, the operation of the rim brake 340 shown in the drawing is achieved, and when the right brake lever 320 is pressed, a separate bar is attached to a side portion of the inner rim 130 such as downward. And a rim brake can be formed to work.

On the lower side of the fixed frame 150, the slope frame 170 on which the saddle 190 and the driving means are mounted is mounted in a pair as a left and right dual structure. The saddle 190 is slightly inclined upward on one side of the slope frame 170, and the portion of the slope frame 170 provided with the saddle 190 is inclined downward and attached to the fixed frame 150. Has become. This ergonomically designed to prevent the user from being inclined in the direction of travel due to inertia while driving, as well as to reduce the distance from the saddle 190 to the lower part of the ground to allow the user's feet to easily touch the ground. .

Although not shown in the drawings, the backrest supporting the user's back while retaining elastic force absorbs a certain impact and is fixed to one side of the fixing frame 150, specifically, the user's back, and thus the waist when driving for a long time. Pain can be prevented from occurring.

At the central portion of each of the slope frames 170, a pair of reinforcement frames 180 are formed extending substantially vertically downward, and the driving wheel 210 is mounted between the pair of reinforcement frames 180. And a pair of the second sprocket 260 is mounted on the outer portion.

The driving means according to the present invention is a pair of first sprockets 240 and a pair of crankshafts connected to the first sprocket 240 by the crank shaft and the crank 230 and the pedal 220, the chain 250 connected thereto. It is mounted on the inner rim 130 of the wheel 100 by being mounted on the middle portion of the hub shaft 280 formed through the reinforcing frame 180 to be connected to the second sprocket 260 and the second sprocket 260. It consists of a fixed wheel 210 in contact with the semi-circular groove 135, the first sprocket 240 and the second sprocket 260 is covered by a protective cover 270 together with a chain 250 and a protective cover ( The upper end of the 270 is connected in the outward direction of the reinforcement frame 180.

The connection structure of the first sprocket 240 and the second sprocket 260 has an inclination corresponding to the extension direction of the reinforcing frame 180, that is, the inclination in the forward direction when the user is seated on the saddle, the distance is the user Corresponding to the calf length of is desirable for proper driving.

The top of the driving wheel 210 is slightly exposed to the top of the slope frame 170, because the rotation of the driving wheel 210 may be a problem for the user's safety on the top of the drive wheel 210 A cover 215 having a corresponding curvature is configured to be coupled to one side of the slope frame 170.

The drive wheel 210 is in constant contact with the semicircular groove 135 having an outer circumferential surface formed in contact with the semicircular groove 135 of the inner rim 130 to correspond to the outer circumferential surface of the drive wheel 210 by the rotation of the drive wheel 210. The friction wheel is generated to rotate the wheel. For this purpose, the driving wheel 210 has a surface that is not too smooth and is preferably made of a silicon material.

Hereinafter, the operation of the outer ring bicycle of the present invention according to the above-described configuration will be described with the accompanying drawings.

When the user is seated on the saddle 190, the slope frame 170 is inclined downward toward the hips of the user so that the user is inclined backward. When the handle 310 is gripped, the upper part of the user's body is vertically formed. . With such a configuration, it is possible to more appropriately prevent the problem of forward forwarding due to inertia while driving, which can contribute to the stability of the user.

When the user rotates the pedal 220, the pair of first sprockets 240 connected to the pedal 220 is rotated to rotate the second sprocket 260 by the chain 250 connected thereto, thereby causing the second The driving wheel 210 connected to the sprocket 260 and the hub shaft 280 also rotates to transmit frictional force to the semi-circular groove 135 in contact with the driving wheel 210 to travel while the wheel 100 rotates. This is done.

Each sprocket (240 260) and chain 250 portion is covered by a protective cover 270 not only does not interfere with the user's driving state, but also in the vertical direction to the slope frame 170 without placing the sprocket in the horizontal direction The sprockets 240 and 260 and the chain 250 portions are formed in the direction of the extended reinforcement frame 180 to shorten the length of the chain 250 so that the chain 250 can be easily separated from the sprockets 240 and 260 during driving. Can be prevented.

The fixed frame 150 is fixed without rotation by the rotation of the roller 160 when the wheel 100 rotates, and when the user pulls the brake lever 320, the rim brake 340 is formed on the inner rim 130 side. Abuts the wheel 100.

In addition, the inner and outer rims (120, 130) can be equipped with an advertising means can also use the paddle bicycle according to the present invention for events or advertising.
