Description

Fitness enhancement and hobbies pedal not bike}

The present invention relates to a pedal-free bicycle for physical strength and hobby life in more detail by providing the improved exercise effect by allowing the bicycle to move forward with the driving force of walking and running, as well as easily reduce the width of the bicycle from time to time and The present invention relates to a pedal-free bicycle for physical fitness and hobby that allows the bicycle to be stably ride even in a narrow passage by allowing it to be enlarged.

Bicycles, which have been used as an important means of transportation for a long time, have recently been in the spotlight as recreational exercise equipments due to the change in the awareness of the five-day week system and exercise, and people who use bicycles for lack of parking space and resource saving In addition to the increasing trend, according to the user's preferences and choices, there are also various types of bicycles.

Currently, the most popular bicycles are connected by chains between the rear wheels and the pedals, so that when a person steps on the pedals, the bicycle can go straight, and multi-gear gears can be used to climb uphill without difficulty. It is a bicycle that is generalized such as the thing (general, leisure), and the installation of a separate shock absorber (mountain mountain) to alleviate the impact when moving the uneven road.

However, it is true that such a bicycle can get a good response for leisure use, but it is difficult to bring out a good response for exercise. Mountaineering requires the economic cost as well as proficiency for ordinary people to ride. There was no way to approach this.

In addition, even if you exercise by bicycle, you have to be patient and spend a lot of time to feel the improved exercise effect. Especially, if you are a beginner, you need not only a lot of effort and time to ride a bicycle, There were no choice but to follow with difficulty and discomfort.

In the present invention is to devise to solve the problems as described above to enable the user to get the exercise effect while the bicycle is moving forward with the driving force to walk or run, and even to beginners can be easily exercise using the bicycle Its purpose is to provide a pedalless bicycle for fitness and hobby.

Still another object of the present invention is to allow the bicycle to stop and slow down when stopping or slowing down, and the user can easily reduce and expand the width of the bicycle when accelerating or walking in narrow alleys. It is to provide a pedal-free bicycle for physical strength and hobby life, so that you can feel the improved exercise effect as well as the hobby life through the bicycle.

The pedalless bicycle for physical fitness and hobby provided by the present invention,

The handle 20 having the structure in which the hand brake 21 is integrally coupled and the hawk 10 to which the front wheel 30 is coupled and fixed, the front wheel 30 coupled to and fixed to the hawk 10 and rotated, Joint frame 50 having one or more connecting links 90 is fixed to the hawk 10 and the shaft insertion, coupled to a plurality of rotating rear wheels 100 to easily change the left, right width of the rear wheel and It is characterized in that it comprises a plurality of rear wheels 100 is fixed and rotated to the end of the joint frame 50.

In addition, the joint frame 50, the support shaft 11 and the shaft of the hawk is fixed to the insertion, the frame head 60 consisting of a plurality of connecting frames 61 integrally, the connecting frame 61 and the horizontal frame ( A plurality of folding frames 70 and 80 are connected to the folding frame 70 and fixed to the link 90 to be folded within a predetermined section, the plurality of rear wheels 100 is coupled and fixed to the other side Horizontal frame 80, the connection frame 61 and the folding frame 70, one or more connecting links 90 for fixing the connection so that the horizontal frame 80, and the folding frame 70 And, it is provided between the horizontal frame 80 is characterized in that it comprises one or more show bar 110 to easily change the left and right width of the folding frame 70 and the horizontal frame.

In addition, one end of the horizontal frame 80 is characterized in that the inclined portion (81) is formed so that it can be easily fixed to the folding frame 70 and the connecting link (90).

In addition, in each direction of the inner side of the horizontal frame 80 is easy to fold the footrest 82 is characterized in that the horizontal frame 80 and the integral or removable configuration.

The pedalless bicycle for physical strength and hobby life provided by the present invention can gain physical strength by exercise at the same time because the bicycle moves with the driving force of the person walking or running, and if it gets tired or hard during the exercise process, Not only can you save stamina, but also has three wheels before and after that you can have a stable movement.

In addition, in narrow alleys, the rear wheels can be as narrow as possible, which can reliably drive bicycles without friction, such as pedestrians and surrounding objects.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and preferred embodiments.

First, the pedal-free bicycle for physical strength and hobby provided by the present invention has a handle 20 and a front wheel 30 having a structure in which the hand brake 21 is integrally coupled as shown in FIGS. The hawk 10 is to be coupled to the hawk 10, the front wheel 30 is rotated and rotated, and the hawk 10 and the shaft is fixed to the rotation, coupled with a plurality of rotating rear wheels 100 is fixed to the left of the rear wheel Consists of a joint frame 50 having one or more connection links 90 so that the right width can be easily changed from time to time, and a plurality of rear wheels 100 fixedly coupled to the ends of the joint frame 50 and rotated. do.

At this time, the joint frame 50 is inserted into the shaft and the support shaft 11 of the hawk, as shown in Figures 2 to 4, a plurality of connecting frame 61 is formed integrally with the frame head 60, the connection A plurality of folding frames 70 for fixing the frame 61 and the horizontal frame 80 by the link 90 to be folded within a predetermined section, and is connected to the folding frame 70, a plurality of rear wheels on the other side One or more connecting links 90 for fixing and connecting the plurality of horizontal frames 80 to which the 100 is coupled and the connection frame 61 and the folding frame 70 and the horizontal frame 80 can be folded. And at least one show bar 110 provided between the folding frame 70 and the horizontal frame 80 to easily change the left and right widths of the folding frame 70 and the horizontal frame. do.

Therefore, it is easy to expand and contract the folding frame as well as the horizontal frame at any time in the left and right directions by the external press. When exercising, the horizontal frame is reduced when the movement is made in the expanded state and when it is stopped or stored in a fixed place. Narrow missions can be used by the following storage.

In addition, since the folding frame 70 and the horizontal frame 80 are mounted with the showbars 110, the width of the rear wheels can be more flexibly adjusted, and a plurality of horizontal frames equipped with the rear wheels are always in a horizontal state. Can be maintained.

On the other hand, the frame (61, 70, 80) can be provided with weight reduction by using a pipe having a circular or polygonal structure.

In addition, one end of the horizontal frame 80 is formed with an inclined portion 81 to be easily connected to the folding frame 70 and the connection link 90, in each direction of the inner side of the horizontal frame 80 As shown in FIG. 4, the easy-folding footrest 82 is configured to be integral with or detachable from the horizontal frame 80.

As shown in FIG. 5, the pedalless bicycle for the physical fitness and hobby life of the present invention having the features as described above is to move forward when the bicycle is walking or running as if the user grabs the handle and pushes the bicycle, naturally It can be expected to increase stamina.

In particular, since it is composed of three wheels, there is no fear of falling, so it is possible to exercise with the bicycle in a stable manner.

In addition, when walking along a narrow road, the showbar 110 may be pulled and then the bicycle may be moved.

At this time, since the bar 110 is extended or reduced to the left or right only when a certain amount of pressure is transmitted, there is no room for reduction or expansion in the process of moving the bicycle, and thus there is no room for a safety accident. .
