Description

Improved carrier type folding kickboard {CARRIER TYPE FOLDABLE KICK BOARD}

The present invention relates to a carrier-type folding kickboard, and more specifically, to a carrier-type folding kickboard, which allows a stable posture to be maintained without easily falling down during transport, and can be stably erected without falling in a folded state. It is intended to provide a carrier-type folding kickboard that allows the rider to do other tasks such as using a mobile phone or making a purchase using both free hands while standing.

For busy modern people, I think the time to move is too precious. So people choose bicycles, motorcycles, cars, etc. However, for busy modern people, the roads in Korea are very stuffy. So I try to take public transport. The most used public transport in large cities is the subway, which usually runs on time.

If the distance to go to the subway is close or the final destination is close to the destination station, the subway is selected without thinking. However, if the distance to the departure station and the distance from the arrival station to the final destination are long, it is again a waste of time and troublesome.

Therefore, the number of people who transfer from the departure station to the departure station and from the arrival station to the destination station using a bicycle or a kickboard is increasing.

However, in Korea, bicycles are allowed to be carried on the subway only on public holidays, which limits their use. On the other hand, kickboards have the advantage of being smaller and easier to carry than bicycles, and can be carried on the subway as well. It is especially widely used by young people.

As a prior art of the conventional folding kickboard, there is a "foldable kickboard" of Republic of Korea Utility Model Registration No. 20-004403 (registered on September 15, 2000).

The foldable kickboard of the registered utility model is designed to be easily carried and stored by assembling a frame and a plate to the handle and the board as a shaft, respectively, and rotating the handle, and folding the handle over the board by the operation of a lever installed on the frame, When transporting, hold the handle of the handle located on the rear wheel side and stand it so that the front wheel is in contact with the ground so that it can be towed and transported in a carrier type.

However, the foldable kickboard of the registered utility model has the following problems.

There is a problem in that transportation becomes inconvenient because only the front wheel touches the ground when towed with a carrier type in a folded state, and it is about to fall unless careful attention is paid like a unipedal cart.

In the folded state, it cannot stand on its own, so you have to keep holding the handle with one hand, so there is a problem that only the other hand can be used when carrying out other tasks such as using a mobile phone or purchasing goods while carrying it.

Also, as a prior art of a foldable kickboard, there is a "folding kickboard" disclosed in International Patent Publication WO2013065978 A1 (published on May 10, 2013).

The foldable kickboard of the International Patent Publication is configured such that the handle support frame is folded over the footrest, and provided with a stand on the rear wheel side, so that it can be towed and transported in a carrier type, and can be erected by the stand during transport.

The foldable kickboard of the International Patent Application Laid-Open has an advantage in that it has a stand at the rear end of the footrest to be towed in a carrier type so as not to fall over during transport.

However, there is a problem in that transport is inconvenient because only the rear wheel touches the ground when towed with a carrier type in a folded state, and it tends to fall if not paying close attention like a unipedal cart.

In addition, since the folding structure for folding the handle support frame and the footrest is located between the lower end of the handle support frame and the tip of the footrest, even if the length of the handle support frame is reduced to shorten the overall length when folded, the overall length is less than the length of the board. Since it cannot be shortened, there is a problem that it takes up a lot of space when stored or loaded in a vehicle.

There is also a "folding kickboard" with three wheels as a prior art of the folding kickboard. Such a foldable kickboard consists of two rear wheels on the left and right, and has the advantage of being able to be transported stably because three wheels including one front wheel and two rear wheels touch the ground when towed in a folded state in a carrier type.

However, this foldable kickboard cannot stand on its own when folded because one front wheel and two rear wheels are in a straight line in the folded state, so you have to hold the handle with one hand. There is a problem in that only the other hand can be used when doing other tasks in parallel, and above all, the three wheels are densely located and thus unstable. These problems are commonly caused by folding the kickboard vertically.

Therefore, the present inventor has repeated research and development to solve all the disadvantages while taking advantage of all the advantages of the prior art and the prior art, and completed the carrier-type folding kickboard of the present invention.

Republic of Korea Registered Utility Model No. 20-004403 (Registered on September 15, 2000) "Foldable Kickboard" "Folding Kickboard" of International Patent Publication WO2013065978 A1 (published on May 10, 2013)

As the front foot plate 11 and the rear footrest 12 are folded, the front end of the front foot 11 and the rear end of the rear foot 12 gradually approach, and the front foot 11 and the rear foot 12 are completely When it reaches just before folding, the hook 102 of the elastic hook 101 fixed to one side of the front end of the front foot plate 11 and the hooking jaw of the hook piece 104 fixed to one side of the rear end of the rear foot plate 12 ( 105) comes close (refer to FIG. 8), and in this state, when the folding operation of the front foot plate 11 and the rear foot plate 12 is further progressed, the hook 102 of the elastic hook 101 becomes the locking piece 103. While in contact with the side of the side, it is bent by its own elasticity and climbs over the clasp 105, and when the front foot plate 11 and the rear foot plate 12 are completely folded, the elastic hook 101 is restored by its own elasticity. The hook 102 is caught on the locking jaw 105 (see FIGS. 13 to 15), and the front foot plate 11 and the rear foot plate 12 are locked in a folded state (see FIGS. 9 to 12).

As described above, in the state in which the front footrest 11 and the rear footrest 12 are folded, the front wheel 60 and the rear wheel 70 are positioned side by side on the same line in the left and right direction.

[Process of folding the steering wheel]

When the unlocking handle 124 of the locking plate 112 rotatably installed on the neck body 30 is pressed in a direction approaching each other, the locking plate 112 is rotated against the elasticity of the torsion spring 114, Accordingly, the locking piece 113 caught in the locking groove 111 is separated from the locking groove 111 .

When the steering wheel 40 is pushed rearward in this state, the neck body 30 coupled to the lower end of the lower handle post 43a constituting the steering wheel 40 is pushed rearward.

At this time, the guide projections 31 formed on both sides of the neck body 30 move along the arc-shaped guide groove 22 formed in the guide plate 21 of the neck guide 20, so that the neck body 20, the handle shaft (41), the handle arm 42, the handle post 43, the entire steering wheel 40 including the handle 45 begins to fold while rotating downwards backward (see FIGS. 16 to 18).

As the steering handle 40 is folded, the hook 122 of the locking plate 121 coupled to the upper end of the lower handle post 43a is connected to the front foot frame 11a of the front foot plate 11 and the front footrest upper surface decorative panel ( 11b) is approached, and when the steering wheel 40 reaches just before being completely folded, the hook 122 of the locking plate 121 comes into contact with the rear end of the front panel upper surface decorative panel 11b while contacting the locking plate (121) rotates against the elasticity of the torsion spring 127, so that the hook 122 passes through the rear end of the front scaffold upper surface decorative panel 11b and the rear end of the front scaffold frame 11a, and the hook 122 is When passing through the rear end of the front footrest upper surface decorative panel 11b and the rear end of the front footrest frame 11a, the locking plate 121 is restored by the elasticity of the torsion spring 127 and the hook 122 is connected to the front footrest frame ( 11a) is caught on the lower surface of the rear end, and the locking piece 123 is caught on the upper surface of the rear end of the front panel upper surface decorative panel 11b, so that the steering handle 40 and the neck body 30 coupled thereto are arbitrarily erected. It is locked without this (see FIGS. 27 to 30).

At this time, the hook 122 hooked on the lower surface of the rear end of the front footrest frame 11a acts as a locking action with respect to the direction in which the steering handle 40 is erected, and the hook 122 hooked on the upper surface of the rear end of the front footrest upper surface decorative panel 11b. The locking piece 123 performs a locking action with respect to the direction in which the steering wheel 40 is further folded, so that the steering wheel 40 is maintained in a folded state.

22 shows the position of the neck body 30 with respect to the neck guide 20 in a state where the steering wheel 40 is erected, and FIG. 25 shows the position of the neck body 30 with respect to the neck guide 20 in a state where the steering wheel 40 is fully folded. The position of the neck body 30 is shown.

In this state, when the middle handle post (43b), the upper handle post (43c), and the handle handle (45) are pressed in the direction of the lower handle post (43a), the lower handle post (43a) is inserted into the middle handle post (43b). The overall length of the handle post 43 is shortened (refer to FIGS. 34 to 36).

After the handle post 43 is adjusted to a desired length, when the clamp lever 44e is pressed, the tightening cam portion 44f tightens the extension piece 44c, and the C-shaped tightening ring 44a that has been relaxed is tightened accordingly. The inner peripheral surface of the lower end of the middle handle post 43b is tightened to the outer peripheral surface of the lower handle post 43a, so that the handle post 43 is fixed in a length-adjusted state.

In addition, when the clamp lever 44e constituting the handle post fixing means 44 provided at the lower end of the upper handle post 43c is pulled upward, the tightening cam portion 44f that tightened the extension piece 44c is the extension piece 44c. The C-shaped tightening ring 44a, which has been relaxed from and tightened the lower outer circumferential surface of the upper handle post 43c, is relaxed, so that the middle handle post 43b and the upper handle post 43c are slidable in the longitudinal direction.

In this state, when the upper handle post (43c) and the handle handle (45) are pressed in the direction of the middle handle post (43b), the middle handle post (43b) is inserted into the upper handle post (43c), and the entire handle post (43) is The length becomes shorter (refer to FIGS. 37 to 39).

After the handle post 43 is adjusted to a desired length, when the clamp lever 44e is pressed, the tightening cam portion 44f tightens the extension piece 44c, and the C-shaped tightening ring 44a that has been relaxed is tightened accordingly. The inner peripheral surface of the lower end of the upper handle post 43c is tightened to the outer peripheral surface of the middle handle post 43b, so that the handle post 43 is fixed in a length-adjusted state.

In the case of adjusting the length of the steering wheel 40 to be long, the length of the lower handle post 43a, the middle handle post 43b and the upper handle post 43c is increased in a state in which the handle post fixing means 44 is relaxed. Next, the handle post fixing means 44 may be tightened again.

In the case of towing and transporting the carrier-type folding kickboard according to the present embodiment in a carrier-type manner, the length of the steering wheel 40 may be lengthened as shown in FIGS. 31 to 33 according to the rider's physical condition, or FIGS. 34 to FIG. As shown at 36, it can be shortened.

In addition, when the carrier-type folding kickboard according to the present embodiment is stored or loaded in a vehicle, the length of the steering wheel 40 is adjusted to a minimum length to minimize the space occupied during storage or transportation.
