Description

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

The present invention relates to a carrier-type foldable kickboard, and more specifically, to maintain a stable posture without falling easily during transportation by towing in a carrier-type manner, and to be able to stably stand without falling over in a folded state, so that the kickboard can be operated during transportation. It is intended to provide a carrier-type foldable kickboard that allows riders to do other things, such as using a mobile phone or purchasing goods, with both hands free.

For busy modern people, I think the time to move is too wasteful. So people choose bikes, motorcycles, cars, etc. However, for busy modern people, our country's roads are too stuffy. So, I try to use public transportation. The most frequently used public transportation in large cities is the subway, which runs on time.

If the distance to take the subway is close or the final destination is close to the arrival station, they will choose the subway without worrying. However, if the distance to the departure station and the distance from the arrival station to the final destination is long, you will worry about whether it will be a waste of time and difficult again.

Therefore, the number of people who transfer using bicycles or kickboards from the departure point to the departure station and from the arrival station to the destination is increasing.

However, in Korea, bicycles can be carried on the subway only on public holidays, so there are restrictions on their use. In contrast, kickboards are smaller and easier to carry than bicycles, and have the advantage that they can be carried on the subway. It is widely used, especially among young people.

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

The collapsible kickboard of the registered utility model is rotated by assembling a frame and a plate to a handle and a board with a shaft, and the handle is folded over the board by the operation of a lever installed on the frame, so that it is easy to carry and store. When transporting, hold the handle part of the handle located on the rear wheel side and stand it so that the front wheel contacts 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 transport is inconvenient because only the front wheels touch the ground when transported by towing in a carrier type in a folded state, so that if careful attention is not paid, it tends to fall.

In a folded state, it cannot stand on its own, so one hand must continue to hold the handle, 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 something while carrying.

In addition, as a prior art of the foldable kickboard, there is a "foldable kickboard" of International Patent Publication WO2013065978 A1 (published on May 10, 2013).

The foldable kickboard of the International Publication Patent is configured so that the handle support frame is folded over the scaffold, and has a stand on the rear wheel side so that it can be towed and transported in the form of a carrier, and can be stood by the stand during transport.

The foldable kickboard of the International Publication Patent has the advantage of having a stand at the rear end of the scaffold so as not to fall while being towed and transported in a carrier type.

However, since only the rear wheel touches the ground during transportation by towing in a carrier type in a folded state, there is a problem in that the transportation is inconvenient because it tends to fall if careful attention is not paid, like a wheelbarrow.

In addition, since the folding structure for folding the handle support frame and the scaffold is located between the lower end of the handle support frame and the front end of the scaffold, 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 in that it takes up a lot of space when stored or loaded into a vehicle.

Also, as a prior art of folding kickboards, there is a "folding kickboard" with three wheels. This folding kickboard consists of two left and right rear wheels, 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 transported by towing in a carrier type in a folded state.

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

Therefore, the present inventors have repeatedly researched and developed 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 foldable kickboard of the present invention.

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

[The 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 rotates 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 .

In this state, when the steering wheel 40 is pushed backward, the neck body 30 coupled to the lower end of the lower handle post 43a constituting the steering wheel 40 is pushed backward.

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

As the steering wheel 40 is folded, the hook 122 of the locking plate 121 coupled to the upper end of the lower handle post 43a is the front scaffold frame 11a of the front scaffold 11 and the front scaffold upper surface decorative panel ( 11b) approaches the rear end, and when the steering wheel 40 reaches just before being completely folded, the hook 122 of the locking plate 121 contacts the rear end of the front scaffold upper surface decorative panel 11b while 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 top 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 scaffold upper surface decorative panel (11b) and the rear end of the front scaffold frame (11a), the locking plate 121 is restored by the elasticity of the torsion spring 127, and the hook 122 is the front scaffold frame ( In addition to being caught on the lower surface of the rear end of 11a), the engaging piece 123 is caught on the upper surface of the rear end of the front scaffold upper surface decorative panel 11b, so that the steering wheel 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 caught on the lower surface of the rear end of the front scaffold frame 11a acts as a locking action in the direction in which the steering wheel 40 is erected, and is caught on the upper surface of the rear end of the front scaffold upper decorative panel 11b. The locking piece 123 has 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 relative to the neck guide 20 with the steering wheel 40 erected, and FIG. 25 shows the position of the neck guide 20 with the steering wheel 40 fully folded. It shows the location of the neck body 30.

[Process of adjusting the length of the steering wheel]

31 to 33, when the clamp lever 44e constituting the handle post fixing means 44 provided at the lower end of the intermediate handle post 43b constituting the steering wheel 40 is pulled up, the extension is extended. The tightening cam portion 44f, which tightened the piece 44c, is released from the extension piece 44c, and the C-shaped tightening ring 44a, which tightens the outer circumferential surface of the lower end of the middle handle post 43b, is released, so that the lower handle post 43a and The middle handle post 43b becomes slidable in the longitudinal direction.

In this state, when the middle handle post 43b, the upper handle post 43c, and the handle knob 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 (see Figs. 34 to 36).

After the handle post 43 is adjusted to the desired length, when the clamp lever 44e is pressed, the tightening cam portion 44f tightens the extension piece 44c, and thus the loose C-shaped tightening ring 44a tightens. Then, the inner circumferential surface of the lower end of the middle handle post 43b is tightened to the outer circumferential 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 tightens the extension piece 44c moves to the extension piece 44c. The C-shaped tightening ring 44a, which was released from the upper handle post 43c 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 knob 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 The length becomes shorter (see Figs. 37 to 39).

After the handle post 43 is adjusted to the desired length, when the clamp lever 44e is pressed, the tightening cam portion 44f tightens the extension piece 44c, and thus the loose C-shaped tightening ring 44a tightens. Then, the inner circumferential surface of the lower end of the upper handle post 43c is tightened to the outer circumferential 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, the length of the lower handle post 43a, the middle handle post 43b, and the upper handle post 43c is lengthened while the handle post fixing means 44 is relaxed. Next, tighten the handle post fixing means 44 again.

When the carrier-type foldable kickboard according to the present embodiment is towed and transported in a carrier-type, the length of the steering wheel 40 is lengthened according to the rider's physical condition as shown in Figs. 31 to 33, or As shown in 36, it can be shortened.

In addition, when storing or loading the carrier-type foldable kickboard according to the present embodiment, the length of the steering wheel 40 can be shortened to a minimum length to minimize the space occupied during storage or transportation.

[Process of folding the folding handle handle]

In the state shown in FIGS. 19 to 21, the locking ring 48d, which is screwed to the handle bar 47a of the foldable handle handle 45 and surrounds the sliding rotation support 48a, is turned in a direction in which the locking ring 48d is relaxed. ) is separated from the slide rotation support (48a), and then the foldable handle handle (45) is rotated while pulling the foldable handle handle (45) pivoting around the slide hinge pin (48c) supported by the hinge long hole (48b) so that it folds.

In this state, the locking ring 48d is turned again in the tightening direction so that the front end of the locking ring 48d is brought into close contact with the slide rotation support 48a to prevent the folding handle knob 45 from rotating arbitrarily (see FIG. 31).

[Carrier type transport process]

As described above, in a state where both the footrest 10 and the steering wheel 40 are folded, the front wheel 60 and the rear wheel 70 contact the ground, and the rider grabs the fixed handle 46 to tow and transport in a carrier type. can

At this time, since the front wheel 60 and the rear wheel 70 are located side by side on the same line in the left and right direction, the kickboard can be transported stably and conveniently without trying to tip over from side to side during transport in a carrier type.

[Process of putting the kickboard on the ground]

As described above, when the front wheel 60 and the rear wheel 70 land on the ground in a state where the footrest 10 and the steering wheel 40 are folded, the headlight 130 and the taillight 140 simultaneously land on the ground, Since the kickboard lands on the ground at 4 points, the kickboard is maintained in a stable posture without falling over arbitrarily (see FIG. 40).

At this time, since the edges of the housings of the headlight 130 and the taillight 140 protrude beyond the lenses, the lenses do not come into direct contact with the ground, preventing damage to the lenses.

[Restore to riding state]

As described above, in order to restore the riding state in a state in which both the scaffold 10 and the steering wheel 40 are folded, first, the process of unfolding the folded folding handle knob 45, the process of erecting the folded steering wheel 40, and the scaffold (10) is carried out sequentially.

[The unfolding process of the foldable handle handle]

31 to 39, turn the locking ring 48d, which is in close contact with the slide rotation support 48a, in a direction in which the front end is in close contact with the slide rotation support 48a, so that the front end is separated from the slide rotation support 48a, and then fold the handle knob Turn (45) so that it is placed on the same line as the slide pivot support (48a), and again turn the locking ring (48d) in the locking direction to wrap the slide pivot support (48a), so that the folding handle knob 45 is unfolded are locked

[The process of setting up the steering wheel]

When the unlocking handle 124 of the locking plate 121 constituting the steering wheel folding locker 120 is pressed forward, the locking plate 121 rotates against the elasticity of the torsion spring 127, so that the hook 122 is In addition to being separated from the lower surface of the rear end of the front scaffold frame (11a), the locking piece 123 is separated from the upper surface of the front scaffold upper surface decorative panel (11b), and the folding state locking between the front scaffold 11 and the rear scaffold 12 is released

In this state, when the steering wheel 40 is rotated upward toward the front, the steering wheel 40 is erected and the guide protrusion 31 of the neck body 30 rotatably supported at the lower end of the steering wheel 40 rotates the neck While being guided along the guide groove 22 of the guide 20, it moves upward toward the front, and when it reaches just before the steering wheel 40 is completely erected, the locking plate 112 constituting the steering wheel erection locker 110 The locking piece 113 approaches the locking groove 111 of the neck guide 20, and at this time, while pressing the unlocking lever 115 of the locking plate 112, the steering wheel 40 is further rotated to lock When the piece 113 coincides with the locking groove 111 and then releases the unlocking lever 115, the locking plate 112 rotates by the elasticity of the torsion spring 114 so that the locking piece 113 locks the locking groove ( 111) and the steering wheel 40 is locked in an upright state.

[The process of spreading the footing]

By pressing the unlocking lever 115 of the elastic hook 101 constituting the footrest folding locker 100, the hook 102 is separated from the locking jaw 105 of the locking piece 104 to unlock the folded state, When the rear footrest 12 is rotated horizontally around the hinge pin 83 of the footrest folding means 80, the front footrest 11 and the rear footrest 12 are unfolded, and the front footrest 11 and the rear footrest When the (12) reaches just before fully unfolding, the hook 92 of the elastic hook 91 comes close to the locking groove 94, and the hook 92 contacts the locking groove 94 while the torsion spring 95 When the hook 92 and the locking groove 94 are completely matched against the elasticity of the elastic hook 91 rotates by the elasticity of the torsion spring 95, the hook 92 is attached to the locking groove 94. It is fitted and the front footrest 11 and the rear footrest 12 are locked in an unfolded state without being arbitrarily folded.
