Abstract
Description
kick board
[0001] The present invention relates to a kickboard with three wheels.
[0002] Kickboarding is a type of riding where you place one foot on the board and roll the other foot on the ground.
[0003] Typically, a stable kickboard consists of a board, one rear wheel installed at the rear of the board, and two front wheels installed at the front of the board, and is designed to control the driving direction by a handle. Some kickboards have handles that can be folded toward the board to reduce the size and make it easy to store and transport.
[0004] Here, kickboards that rotate the entire front wheel by turning the handlebar have a problem in that the entire front wheel turns suddenly, causing the rider to fall off the kickboard or the kickboard to fall over when driving at high speeds.
[0005] To improve this, a kickboard was developed that changes direction by tilting only the body. However, the turning radius varies depending on the rider's skill level, and beginners have difficulty turning quickly, making it difficult to make large turns or go in the desired direction.
[0006] Meanwhile, riders often find themselves needing to carry items of their own, depending on their preferences. Conventional kickboards typically feature a separate storage bag attached to the handlebar. This structure, which operates based on the principle of steering through the weight of the kickboard itself, involves not only the rider's weight but also the weight of their luggage. The center of gravity of both the rider and the items shifts simultaneously, significantly increasing the risk of accidents during directional changes.
[0007] That is, due to the nature of the steering, the steering wheel tilts regardless of will due to the weight of the bag. More specifically, by adding weight to the steering wheel with a high center of gravity, if the steering wheel tilts while driving or parking, the weight shifts to one side and the center of gravity is lost. This is particularly dangerous when driving at high speeds, so it has a structural problem that can cause safety accidents.
[0008] The present invention has been devised to solve the problems of the above-mentioned prior art, and the purpose of the present invention is to provide a kickboard that can forcibly change direction by tilting the handle and can drive stably by preventing the load from being tilted to one side even when driving while carrying the load by installing a storage unit that does not participate in steering.
[0009] In addition, the purpose is to provide a kickboard that can be folded by standing up the footrest instead of folding the control unit by lying it down, that can be easily pulled and moved while being stably erected through training wheels, and that can easily have the footrest replaced to accommodate the rider's body.
[0010] In order to achieve this purpose, the present invention is achieved by a kickboard including a boardable footrest, a steering unit provided at the front end of the footrest, front wheels rotatably installed on both sides of the steering unit and having their direction changed by the steering unit, a horizontal maintenance unit that supports and restrains the steering unit, a rear wheel unit including at least one rear wheel that supports the footrest at the rear end of the footrest, and an operating unit that includes a pole connected to the steering unit and a handle fixed to the upper end of the pole and operates the steering unit, wherein the driving direction is changed when the operating unit is tilted to the left or right.
[0011] In addition, when the operating unit is tilted to the left or right, the footrest is tilted together, and the horizontal maintenance unit maintains a stationary posture, but only the front wheel can change direction in the direction in which the operating unit is tilted.
[0012] In addition, the steering unit,
[0013] A steering block connected to the footrest and the pole and rotatably coupled to the horizontal maintenance unit and rotating left or right together with the footrest and the pole from the horizontal maintenance unit, a direction changing unit rotatably coupled to the horizontal maintenance unit on both sides of the horizontal maintenance unit and each coupled to the front wheel, and a link unit having both ends rotatably connected to the direction changing unit and moving left or right by the operation of the steering block, wherein when the link unit moves to the right, the front wheel can be turned to the right, and when the link unit moves to the left, the front wheel can be turned to the left.
[0014] In addition, the steering unit,
[0015] The steering block further includes a link operating unit that rotates together with the steering block on one side thereof, and a restraining unit that restrains the link operating unit on one side thereof and moves left or right together with the link operating unit according to the rotation of the link operating unit, wherein, based on the rotational center axis of the steering block, when the link operating unit rotates to the left, the link unit moves to the left and the front wheel turns to the left, and when the link operating unit rotates to the right, the link unit moves to the right and the front wheel turns to the right.
[0016] Additionally, the footrest can be folded from the steering unit.
[0017] In addition, the kickboard further includes an auxiliary wheel at the tip of the footrest, and when the footrest is folded, the auxiliary wheel rotates together, and when the footrest is completely folded, the auxiliary wheel comes into contact with the ground to stand the kickboard up, and the kickboard can be easily moved through the auxiliary wheel.
[0018] In addition, the kickboard further includes a storage unit that is detachable from the horizontal maintenance unit, and even if the kickboard changes direction, the storage unit maintains a stationary posture in the same manner as the horizontal maintenance unit, thereby preventing the kickboard from having its center of gravity shifted to the left or right due to the storage unit or the load stored in the storage unit.
[0019] In addition, the above foothold part,
[0020] The footrest is connected so as to be rotatable to the left or right from the rear wheel portion, and the footrest can be rotated within a set angle range from the rear wheel portion.
[0021] In addition, the above foothold part,
[0022] The footrest can be detached from the kickboard so that it can be replaced with a size that corresponds to the rider's body type.
[0023] Additionally, it may further include an elastic body that restores the steering unit to its original position.
[0024] According to the present invention, when a driver tilts the steering wheel to the left or right, the front wheels can be forcibly turned in the direction of tilt, enabling a quick change of direction and further minimizing the turning radius.
[0025] Additionally, riders can learn how to ride a kickboard naturally and stably by naturally leaning in the direction the handlebars are tilted.
[0026] Additionally, when changing direction, the rear wheels remain vertical and only the footrest tilts, allowing for more stable driving.
[0027] Additionally, the footrest folds down, allowing for storage even in tight spaces.
[0028] Additionally, the training wheels rotate together when the footrest is folded, allowing the kickboard to be set up stably and moved easily.
[0029] Additionally, the handle, footrest, and front wheel are restored to their original positions by the elastic body, making it more stable and easier to move the kickboard.
[0030] Additionally, by limiting the rotation angle of the footrest, more stable driving is possible.
[0031] In addition, even when driving with a load in the storage compartment, the storage compartment does not participate in steering, so the load can be prevented from tilting or drifting, and furthermore, the kickboard can be driven stably and the kickboard can be prevented from falling over, allowing for stable parking.

[0043] A preferred embodiment of the present invention will be described in more detail with reference to the attached drawings, but already well-known technical parts will be omitted or compressed for the sake of brevity.
[0044] As illustrated in FIGS. 1 to 12, a kickboard according to an embodiment of the present invention includes a footrest (1), a front wheel (2), a rear wheel (3), a horizontal maintenance unit (9), a steering unit (4), and an operating unit (5). In addition, a hinge unit (415), an auxiliary wheel (6), an elastic body (7), and a storage unit (8) may be included.
[0045] The footrest (1) is a means of serving as a footrest for the rider when riding a kickboard, and includes a support (11) and a support panel (12).
[0046] The support (11) is a means for supporting the support panel (12), and is formed as a roughly circular or polygonal bar. Two of them are provided, and the rear ends are each fitted into the first foot plate connecting portion (31) described later, and the other ends are each fitted into the second foot plate connecting portion (414) described later. A detailed description thereof will be described later.
[0047] The support panel (12) is a means of supporting the rider when riding the kickboard, and is formed as a roughly rectangular panel, placed on the upper part of the support (11), and connected to the support (11).
[0048] The front wheels (2) are provided as a means to support the front of the kickboard, and are provided in two pieces, positioned in front of the footrest (1), and each is screw-connected to a direction-changing part (43) to be described later. An explanation thereof will be provided later.
[0049] The rear wheel part (3) is arranged at the rear of the footrest part (1) and includes a first footrest joint part (31), a wheel support part (32), a rear wheel (33), and a joint shaft (34).
[0050] The first footrest joint (31) is a means for causing the footrest (1) to tilt together when the driver's load or the handle (52) tilts, and is formed in an approximately rectangular parallelepiped shape, and a first insertion hole (311) corresponding to a support (11) is formed on the front, and a first female screw (312) for fixing the support (11) is formed on the bottom surface in vertical communication with the first insertion hole (311). Accordingly, when the support (11) is inserted into the first insertion hole (311) and a screw is inserted into the first female screw (312) and tightened, the support (11) is firmly fixed to the first footrest joint (31), and when the screw is loosened, the support (11) can be removed from the first footrest joint (31).
[0051] In addition, a first coupling hole (313) into which a coupling shaft (34) is inserted is formed through the front center of the first foot plate coupling portion (31). A description thereof will be provided later.
[0052] The wheel support (32) is a means for supporting the rear wheel (33), and is formed with a roughly flat shape in the shape of a "┗┛", and a wheel coupling hole (321) for coupling the rear wheel (33) is formed at the rear end. Accordingly, while the rear wheel (33) is inserted into the wheel support (32), a bolt is passed through the wheel coupling hole (321) and the rear wheel (33), and then a nut is coupled to fix the rear wheel (33) to the wheel support (32).
[0053] In addition, a second coupling hole (322) into which a coupling shaft (34) is fitted is formed through the front center of the wheel support member (32). Accordingly, when the coupling shaft (34) is fitted into the first coupling hole (313) of the first foot plate coupling member (31), the rear end of the coupling shaft (34) protrudes through the second coupling hole (322), and a nut is fitted thereto to couple the first foot plate coupling member (31) and the wheel support member (32). Accordingly, the first foot plate coupling member (31) can rotate from the wheel support member (32) with respect to the coupling shaft (34). A description thereof will be given later.
[0054] Here, the rear wheel part (3) may further include a protrusion (314) and a guide groove (323) that limit the rotation angle of the wheel support part (32).
[0055] That is, a protrusion (314) is formed protruding around the first coupling hole (313) on the rear side of the first footrest coupling part (31), and a guide groove (323) corresponding to the protrusion (314) is formed on the front side of the wheel support part (32). Accordingly, the rotation angle of the first footrest coupling part (31) from the wheel support part (32) is limited to not exceed approximately 30° to the left or right. Accordingly, the rear wheel (33) is prevented from getting caught on an obstacle and the wheel support part (32) is prevented from rotating excessively from the first footrest coupling part (31), thereby enabling stable driving and further preventing safety accidents.
[0056] The rear wheel (33) is inserted into the wheel support member (32) as a means of supporting the rear of the kickboard and is secured to the wheel support member (32) with the bolts and nuts described above. Accordingly, the rear wheel (33) can rotate freely and stably from the wheel support member (32).
[0057] The horizontal maintenance member (9) is a means for supporting the steering block (41) and the direction changing member (43). A support member (91) in the shape of a roughly long bar that is connected to the direction changing member (43) is arranged on the upper part of the steering block (41). A first hole (91a) penetrates downward through the upper surfaces of both sides of the support member (91), and a third connecting hole (93) for connecting a receiving part (8) to be described later penetrates vertically between the first holes (91a) on both sides. In addition, a connecting member (92) corresponding to the link insertion hole (411) is provided on the lower surface of the support member (91), and a second through hole (92a) corresponding to the first through hole (412) is formed through the front surface of the connecting member (92). A description thereof will be described later.
[0058] The steering unit (4) is a means for setting the direction of the front wheel (2), and includes a steering block (41), a center axis (47), a direction changing unit (43), and a link unit (44). Here, a link operating unit (45) and a restraining unit (46) may be further included.
[0059] The steering block (41) rotates together with the footrest (1) and the restraint member (46) to be described later. A link insertion hole (411) corresponding to the connecting piece (92) of the horizontal maintenance member (9) is formed at the top, and a first through hole (412) into which a central axis (47) to be described later is fitted is formed at the front. In addition, the steering block (41) is provided with a pole insertion part (413) corresponding to a pole (51) to be described later at the rear, and is connected to the rear of the steering block (41) by an extension part (416). In addition, the steering block (41) is provided with a second foot plate coupling portion (414) corresponding to the support (11) at the bottom of the pole insertion portion (413), and a second insertion hole (414a) corresponding to the support (11) is formed on the rear surface of the second foot plate coupling portion (414), and a second female screw (414b) vertically connected to the second insertion hole (414a) is formed on the bottom surface of the second foot plate coupling portion (414). Accordingly, when the front end of the support (11) is inserted into the second insertion hole (414a) and a screw is fastened to the second female screw (414b) and tightened, the support (11) is firmly fixed to the second foot plate coupling portion (414), and when the screw is loosened, the support (11) can be separated from the second foot plate coupling portion (414). Therefore, by attaching and detaching the footrest (1) from the first footrest joint (31) and the second footrest joint (414), the footrest (1) can be easily replaced with a footrest (1) corresponding to the age or body of the driver.
[0060] The central shaft (47) is a means for connecting the horizontal maintenance unit (9) and the steering block (41). The rear end of the central shaft (47) is passed through the first through hole (412) and the second through hole (92a) while the connecting piece (92) of the horizontal maintenance unit (9) is fitted into the link insertion hole (411), and then a nut is fastened to the rear end of the central shaft (47). Accordingly, the steering block (41) can rotate from the horizontal maintenance unit (9) about the central shaft (47). An explanation thereof will be provided later.
[0061] The direction changing part (43) is a means for turning the front wheel (2), and is provided in two pieces, formed symmetrically, and arranged on both sides of the horizontal maintenance part (9). In addition, the direction changing part (43) includes a body having a substantially rectangular parallelepiped shape, and a second hole (431) corresponding to the first hole (91a) is formed downwardly through the upper surface of the body, and a wheel engaging piece (432) for engaging the front wheel (2) is formed protruding downwardly on the lower surface of the body. At this time, a wheel engaging hole (432a) is formed through the side surface of each wheel engaging piece (432). First, the front wheels (2) are each pressed against the wheel engaging pieces (432), and then the front wheels (2) and the wheel engaging holes (432a) are each penetrated with bolts, and then nuts are each fastened to the protruding bolts. Accordingly, the front wheels (2) are restrained by the wheel engaging pieces (432), but can rotate freely. Next, while aligning the second hole (431) with the lower portion of the first hole (91a), a bolt is passed through the first hole (91a) and the second hole (431), and a nut is fastened to the protruding bolt. Accordingly, the direction changing part (43) can rotate from the support piece (91). A description thereof will be provided later.
[0062] Meanwhile, the direction change part (43) is formed with a protruding part (433) protruding forward on the front of the body to be connected to the link part (44), and a first connecting hole (433a) corresponding to the second connecting hole (441) of the link part (44) is penetrated downward through the upper surface of the protruding part (433). A description thereof will be given later.
[0063] The link portion (44) is a means for operating the direction changing portion (43) together, and is formed in the shape of a roughly long square bar, with a second coupling hole (441) corresponding to the first coupling hole (433a) penetrating downwards on both upper surfaces. Thereafter, while the link portion (44) is pressed against the lower surface of the protruding piece (433), the first coupling hole (433a) and the second coupling hole (441) are each penetrated with a bolt, and then a nut is fastened to each of the protruding bolts. Accordingly, the two direction changing portions (43) are linked by the link portion (44). A description thereof will be given later.
[0064] The link operating part (45) is a means for operating the second link, and is formed to protrude from the front of the steering block (41) and is positioned above the first through hole (412). At this time, the link operating part (45) is positioned above the link part (44) and is positioned at a predetermined distance from the upper surface of the link part (44). Accordingly, when the steering block (41) rotates, the link operating part (45) also rotates, and a detailed description thereof will be described later.
[0065] The restraint member (46) is a means for restraining the link operating member (45), and is formed protrudingly on the upper surface of the link operating member (44) and is disposed on both sides of the link operating member (45). Accordingly, when the steering block (41) rotates, the link operating member (45) moves, and the link operating member (45) moves the restraint member (46). When the restraint member (46) moves, the link member (44) moves, and when the link member (44) moves, the direction changing member (43) turns in the direction in which the link member (44) moves, and the direction of the front wheel (2) changes. A detailed description thereof will be described later.
[0066] The hinge part (415) is a means for rotating the second foot plate coupling part (414) from the pole insertion part (413). A hinge axis (415a) is arranged between the pole insertion part (413) and the second foot plate coupling part (414), but is arranged at the rear of the pole insertion part (413). A lever (415b) is fitted and coupled to the hinge axis (415a). Accordingly, when the lever (415b) is rotated upwards around the hinge axis (415a), the second foot plate coupling part (414) is released from the pole insertion part (413), and the second foot plate coupling part (414) can rotate around the hinge axis (415a). When the lever (415b) is rotated downwards, the pole insertion part (413) and the second foot plate coupling part (414) are firmly coupled and fixed. Accordingly, the footrest portion (1) can be folded by rotating the footrest portion (1) upwards through the lever (415b). Here, the hinge portion (415) uses a known technology, so the detailed structure will be omitted.
[0067] The operating unit (5) is a means for rotating the steering block (41), and includes a pole (51) and a handle (52).
[0068] The pole (51) is a means for supporting the handle (52), and is formed as a long round bar or pipe with a roughly truncated side, the lower end is inserted into and fixed to the pole insertion portion (413), and the upper end is combined with the handle (52).
[0069] Meanwhile, the pole (51') may further include a length adjustment part (51a) that can adjust the length. More specifically, the pole (51') may be changed to an antenna type, and a length adjustment part (51a) using a lever type or a screw type, etc., may be installed in the middle of the pole (51'). Accordingly, the length of the pole (51') can be adjusted through the length adjustment part (51a), and further, the length of the pole (51') can be adjusted to correspond to the height of the driver, thereby enabling comfortable driving. Here, the length adjustment part (51a) uses a well-known or publicly known technology, so a detailed description thereof will be omitted.
[0070] The handle (52) is a means for the driver to grip, and is connected to the top of the pole (51) and arranged in a “T” shape with the pole (51).
[0071] Accordingly, when the handle (52) is tilted to the left or right while the handle (52) is held, the steering block (41) rotates in the tilted direction, and the link operating part (45) moves the restraint part (46) to move the link part (44). When the link part (44) moves, the direction changing part (43) rotates around the first hole (91a) and turns in the direction in which the link part (44) moves, and at the same time, the front wheel (2) turns in the direction in which the handle (52) is tilted, thereby changing the driving direction. That is, when the handle (52) is tilted, the driver's load also naturally moves in the direction in which the handle (52) is tilted, and at the same time, the front wheel (2) naturally turns in the direction in which the handle (52) is tilted, thereby enabling stable driving.
[0072] For example, when the rider's body is tilted, the front wheel (2) naturally turns in the direction in which the body is tilted, but since it does not turn right away but gradually, the turning radius of the kickboard inevitably increases. However, the present invention can forcibly turn the front wheel (2) simply by tilting the handle (52) of the kickboard, so that the kickboard can turn right away, and thus the turning radius can be reduced, so that it can turn easily even on a narrow road. In addition, the footrest (1) can be tilted even when the rear wheel (33) is standing vertically, so that it can ride more stably.
[0073] Normally, when the rider's body tilts, the rear wheel (33) also tilts. However, if the rear wheel (33) tilts excessively or the road surface is slippery, the kickboard may fall in the direction in which it is tilted. However, the present invention allows only the footrest (1) to tilt while the rear wheel (33) remains vertical, thereby enabling stable driving.
[0074] The auxiliary wheel (6) is a means for stably setting up the kickboard when the footrest (1) is folded. An auxiliary wheel support (61) protrudes from the front of the second footrest joint (414), and the auxiliary wheel (6) is connected to the auxiliary wheel support (61) using bolts and nuts. Accordingly, when the footrest (1) is folded, the auxiliary wheel (6) protrudes downward and makes contact with the ground to form a triangle with the front wheel (2), thereby stably setting up the kickboard on the road surface. In addition, the auxiliary wheel (6) makes it easy to move the kickboard.
[0075] Here, a restraining means (not shown) may be further provided to the pole (51) or the footrest (1) to maintain the footrest (1) in a folded state. Of course, the kickboard can be maintained in a folded state by the auxiliary wheels (6), but a separate restraining means may also prevent the folded footrest (1) from unfolding due to external impact.
[0076] The elastic body (7) is a means for returning the operating unit (5) to its original position, and at least one return spring or the like is used. It is fitted to the central shaft (47) and placed between the steering block (41) and the connecting piece (92), and one end is bound to the connecting piece (92) and the other end is bound to the steering block (41). Accordingly, when the rider tilts the handle (52), the steering block (41) rotates, and when the force applied to the handle (52) is released, the steering block (41) is restored to its original position by the elastic body (7), and the operating unit (5) and the front wheel (2) are also restored to their original positions. Accordingly, the kickboard can be placed more stably on the ground when the footrest (1) is folded, and furthermore, more stable movement is possible.
[0077] The storage section (8) is a means for storing or transporting the driver's luggage, and includes a storage support (81) and a storage box (82).
[0078] The storage support (81) is a means for supporting the storage box (82), and the front side is formed in a roughly "ㅗ" shape, and holes corresponding to the third connecting hole (93) are passed through both sides of the lower portion, and the upper portion is connected to the storage box (82). Accordingly, when the lower portion of the storage support (81) is pressed against the support piece (91), the hole of the storage support (81) and the third connecting hole (93) are passed through with a bolt, and then connected with a nut, the storage support (81) is firmly fixed to the support piece (91). In addition, the nut can be loosened to separate the storage support (81) from the support piece (91), so that it can be easily removed.
[0079] The storage box (82) is a means for storing or transporting the driver's luggage, and can be roughly a basket or a bag, and is firmly fixed to the upper part of the storage support (81). At this time, the connecting means (not shown) of the storage support (81) and the storage box (82) uses a known or publicly known technology, so a detailed description thereof is omitted.
[0080] Meanwhile, even if a heavy load is placed in the storage box (82), it does not affect the direction of the kickboard in any way. That is, the horizontal support member (9) is only connected to the steering block (41) and supports the steering block (41) and is unrelated to the direction of the kickboard. More specifically, when the direction of the kickboard is changed while a heavy load is placed in the storage box (82), only the footrest member (1), the steering block (41) and the operating unit (5) tilt, and since the horizontal support member (9) maintains a stationary position, the storage box (82) can always maintain its original position. Therefore, since the storage box (82) can maintain a fixed position, it is possible to prevent the center of gravity of the load placed in the storage box (82) from being shifted to the left or right of the kickboard, and it does not affect the direction of the kickboard in any way, and furthermore, it is possible to drive stably.
[0081] For example, existing kickboards have no place to install a storage box (82), so they are installed on the handle or pole. In this case, if the direction of the kickboard is changed while the storage box (82) is loaded, the storage box (82) rotates or tilts together, which may cause a safety accident in which the kickboard falls over. In other words, when the rider turns the handle, the stored luggage also needs force to rotate, making it difficult to rotate the handle, and even after the handle is rotated, the handle overrotates due to rotational inertia. This may cause a safety accident in which the kickboard cannot go in the desired direction and collides with an obstacle or falls over. On the other hand, in the case of the type in which the kickboard is rotated by tilting the footrest to the left or right, the storage box (82) also tilts together when the footrest and handle are tilted, which may cause the center of gravity to be excessively biased to one side, resulting in a safety accident in which the kickboard falls over. In addition, if the storage box (82) is left tilted even slightly when parking the kickboard, the storage box (82) will tilt more and more over time, which will cause the kickboard to fall over and collide with the ground, resulting in damage to the kickboard.
[0082] However, the present invention installs the storage unit (8) on the horizontal maintenance unit (9) that does not participate in steering and always maintains a horizontal position, so that even if the kickboard changes direction, the storage unit (8) can always maintain a constant position, thereby enabling stable driving and further preventing accidents from occurring. In addition, even if the operating unit (5) is tilted when parking the kickboard, the load stored in the storage unit (8) holds the kickboard with a vertical load, thereby preventing the kickboard from falling over and enabling stable parking.
[0083] In explaining the present invention described above, even if the embodiments are different, the same reference numbers are used for the same components, and the description thereof may be omitted as necessary.
[0084] As described above, although the specific description of the present invention has been made by way of embodiments with reference to the attached drawings, the above-described embodiments are only described as preferred examples of the present invention, and therefore the present invention should not be understood as being limited to the above-described embodiments. Therefore, in addition to what has been described above, a person having ordinary skill in the art to which the present invention pertains will be able to easily implement other forms of the present invention within the same scope as the above-described embodiments, or implement inventions in an equivalent field to the present invention, based only on the description of the embodiments of the present invention.
