Description

A kickboard brake device and a kickboard safety device comprising the same {THE KICKBOARD BRAKE DEVICE AND THE KICKBOARD SAFETY DEVICE COMPRISING THE SAME}

The present invention relates to a kickboard brake device and a kickboard safety device including the same, and more particularly, to a kickboard operator by minimizing damage to wheels and interference during kickboard operation due to kickboard braking and improving driving stability and braking stability. The present invention relates to a kickboard brake device capable of improving the satisfaction of the user and a kickboard safety device including the same.

A kick-board is a means of transportation used by users of various age groups, from children to adults. In general, a kickboard is a board corresponding to a footrest, front/rear wheels installed on the front/rear side of the board, and connected to the front wheel. It consists of a handlebar that allows the user to manipulate the rotation direction of the front wheel.

In addition, a braking means for braking the kickboard while the kickboard is running is also provided in the kickboard. The braking means includes a hand brake mounted on a handlebar and configured to transmit braking force to the rear wheel when pressurizing, and a handbrake disposed above the rear wheel when pressurizing and a brake cap in frictional contact with the rear wheel, and the like.

Braking by the handbrake has a disadvantage in that the braking effect of the wheel is limited because the braking force is transmitted from the handlebar to the wheels through the brake wire. Therefore, large and small accidents frequently occur at the actual kickboard operation site for a kickboard user equipped with a hand brake.

In addition, as shown in FIG. 1 , the method of braking the rear wheel 1 by pressing the brake cap 2 disposed on the upper side of the rear wheel 1 with the foot has a better braking effect than the hand brake method, but the brake cap 2 is in integrated contact with the rear wheel 1 and accordingly the rear wheel 1 is pressed against the ground to implement kickboard braking, so there is a problem in that the rear wheel 1 is continuously worn.

When the rear wheel (1) is worn, the braking effect is gradually reduced, thereby impairing the driving stability of the kickboard. In particular, in the case of the rear wheel (1) with LEDs attached, the LED may be damaged due to wear. In spite of causing considerable risk and cost loss in operation, a general kickboard is not equipped with any means such as checking or checking the wear of the rear wheel 1 at all.

In addition, in describing the embodiment of the present invention, if it is determined that a detailed description of a related known configuration or function interferes with the understanding of the embodiment of the present invention, the detailed description thereof will be omitted. In addition, embodiments of the present invention will be described below, but the technical spirit of the present invention is not limited thereto and may be variously implemented by those skilled in the art.

Throughout the specification, when a part is "connected" with another part, this includes not only the case of being "directly connected" but also the case of being "indirectly connected" with another element interposed therebetween. . Throughout the specification, when a part "includes" a certain element, it means that other elements may be further included, rather than excluding other elements, unless otherwise stated. In addition, in describing the components of the embodiment of the present invention, terms such as first, second, A, B, (a), (b), etc. may be used. These terms are only for distinguishing the components from other components, and the essence, order, or order of the components are not limited by the terms.

2A to 2D respectively show the configuration of the brake device 100 and the auxiliary scaffold 200 when the kickboard is in a normal state according to an embodiment of the present invention. As shown in FIGS. 2A and 2B , the kickboard safety device 1000 according to an embodiment of the present invention may include a brake device 100 and an auxiliary footrest 200 .

For reference, in the present specification, terms of “normal state” and “braking state” are defined as the state of the kickboard in this specification, and the 'normal state' is a brake device ( 100) refers to a state in which the brake device 100 is arranged to be raised, and the 'braking state' refers to a state in which the user presses the brake device 100 to brake the kickboard and the brake device 100 is disposed downward, thereby contacting the ground.

The brake device 100 according to an embodiment of the present invention is a device for braking a kickboard. In a normal state of driving the kickboard, it is raised by elastic force, and in a braking state of braking the kickboard, it is arranged lowered by the user's pressure. It is characterized in that the braking of the kickboard is implemented by friction with the ground 10 (for example, refer to FIGS. 5A and 5B below).

In addition, the brake device 100 according to an embodiment of the present invention is rotatably elastically coupled to one end of the main scaffold 20 without being overlapped with the main scaffold 20, and accordingly, foot motion for driving and User convenience can be significantly improved by preventing foot motions for braking from interfering with each other.

As shown in FIGS. 2A and 2B , the brake device 100 according to an embodiment of the present invention may include a base plate 110 , a foot pad 140 , a braking pad 150 , and the like. there is.

The base plate 110 is elastically coupled to at least a partial region of the main footboard 20 , and a space recessed inwardly (eg, a rectangular inner recessed space, etc.) is defined as a rotational space of the rear wheel 30 . can be More specifically, the base plate 110 according to the present invention includes a pair of parallel plates 111 (refer to FIGS. 4a and 4b below) forming an inner recessed space defined as a rotational space of the rear wheel 30, and, It may be composed of a vertical plate 112 (refer to FIGS. 4A and 4B below) interconnecting one end of the pair of parallel plates 111, so that the inner recessed space faces the front of the kickboard and the vertical plate 112 ) may be composed of a “C”-shaped plate facing the rear of the kickboard.

Regarding the shape of the vertical plate 112 , according to a further embodiment of the present invention, both rear corners of the vertical plate 112 may be finished to be inclined, as shown in FIG. 2E , and accordingly, the vertical plate 112 may be finished. ) may have a trapezoidal shape. In this configuration, the foot pad 140 coupled to the upper surface of the vertical plate 112 and the braking pad 150 coupled to the lower surface of the vertical plate 112 also have a trapezoidal shape substantially the same as the vertical plate 112 . can have As described above, by slanting both rear corners of the vertical plate 112 , the foot pad 140 , and the braking pad 150 , it is possible to prevent jamming during kickboard driving and further improve driving convenience.

The length of the pair of parallel plates 111 may be greater than the radius of the rear wheel 30, for example, the difference may be about 3-9 cm. For reference, if the braking device is formed to have a long length backward from the kickboard body, it may be difficult for the kickboard operator to perform both driving and braking skillfully while riding the kickboard. Therefore, the brake device 100 according to an embodiment of the present invention utilizes the space of the rear wheel 30 to make the length of the additional rearward extension of the brake device 100 relatively short, so that the kickboard driver can perform the braking operation. It is possible to improve the overall aesthetics of the kickboard device while not causing discomfort in performing.

The length of the vertical plate 112 may be defined as the width of the base plate 110 , which may be substantially equal to or smaller than the width of the main scaffold 30 . In addition, one end of each of the pair of parallel plates 111 is coupled to the vertical plate 112, and the other end of each of the pair of parallel plates 111 has a shaft insertion hole 113 (see FIGS. 4a and 4b below). is provided so that the base plate 110 according to the present invention is rotatably coupled to the main scaffold 20 through the wheel shaft 130 of the rear wheel 30 (refer to FIGS. 4A and 4B below), and at the same time elastic coupling means ( 120 (see FIG. 4a) may be elastically coupled to the main scaffold 20, and this configuration will be described in more detail in FIG. 4 below.

In addition, as shown in Figure 2, the thickness of the base plate 110 may be smaller than the thickness of the main scaffold 20, or according to another embodiment of the present invention, the thickness of the base plate 110 is the main scaffold ( 20) may be implemented substantially the same as the thickness.

The foot pad 140 may be coupled to at least a partial area of the upper surface of the base plate 110 , and more specifically, may be coupled to a partial area of the upper surface of the vertical plate 112 . The foot pad 140 according to an embodiment of the present invention includes an upper surface to which a user's foot is pressed during braking of a kickboard, a lower surface coupled to the upper surface of the vertical plate 112 , and a plurality of interconnecting upper and lower surfaces. It may have a hexahedral shape composed of side surfaces.

For example, as shown in FIG. 2 , the foot pad 140 may be implemented as a hexahedron having a trapezoidal cross-sectional shape in which the length of the upper side is shorter than the length of the lower side, but this is for easy understanding of the present invention. It is only an example and may be implemented as a hexahedron having a cross-sectional shape of a trapezoid in which the length of the upper side is longer than the length of the lower side, or a hexahedron having a cross-section of another shape (eg, a square, a hexagon, etc.), an octahedron or a cylinder It is also possible to be implemented as other shapes.

Also, the length of the foot pad 140 may be substantially equal to or smaller than the width of the base plate 110 . Here, the upper surface of the foot pad 140 is implemented in parallel with the base plate 110 so that the upper surface of the foot pad 140 may not be parallel to the auxiliary footrest 200 in a normal state (for example, see FIG. 2B ) ), according to an additional embodiment of the present invention, the upper surface of the foot pad 140 is implemented in a form that is highly inclined to the rear, so that when the brake device 100 descends, the bottom surface of the foot pad 140 is compared with the normal state. It can also be made more parallel. However, this configuration of the foot pad 140 is only an example for easy understanding of the present invention, and thus the shape of the foot pad 140 is implemented in various shapes according to user convenience or implementation examples of the kickboard device. It is also possible to

The foot pad 140 may be coupled to the base plate 110 , more specifically, to the upper surface of the vertical plate 112 through screw coupling or the like. Therefore, not only can the rigidity of the foot pad 140 be maintained while the kickboard is running, but when the user wants to replace the damaged foot pad 140, the foot pad 140 detachably coupled to the base plate 110 is installed. The replacement of the foot pad 140 can be easily performed by coupling the new foot pad 140 after the disengagement.

Alternatively, according to another embodiment of the present invention, the foot pad 140 may be integrally formed with the base plate 110 by, for example, injection molding, welding, or the like, and additionally on the foot pad 140 . A material such as rubber or plastic may be covered. In this case, since the bonding process between the base plate 110 and the foot pad 140 can be minimized, the manufacturing process of the brake device 100 can be further simplified and the strength can be made more robust.

The braking pad 150 may be coupled to at least a partial region of the lower surface of the base plate 110 , and more specifically, may be coupled to the lower surface of the vertical plate 112 . The braking pad 150 according to an embodiment of the present invention has an upper surface coupled to a lower surface of the vertical plate 112, a lower surface that is in contact with the ground 10 when braking the kickboard, and the upper and lower surfaces interconnecting the It may have a hexahedral shape composed of a plurality of side surfaces.

For example, as shown in FIG. 2 , the braking pad 150 may be implemented as a hexahedron having a trapezoidal cross-sectional shape in which the length of the upper side is longer than the length of the lower side, but this is for easy understanding of the present invention It is only an example, and it can be implemented as a hexahedron having a cross-sectional shape of a trapezoid in which the length of the upper side is shorter than the length of the lower side, or it can be implemented in various forms such as a hexahedron, octahedron, or cylinder having a cross-section such as a rectangle or a circle. do.

In addition, the length of the braking pad 150 may be implemented to be substantially equal to or smaller than the width of the base plate 110, and when the brake device 100 descends in the braking state of the kickboard, the braking pad 150 is The height of the braking pad 150 may be dimensioned so that sufficient braking force for braking the kickboard can be generated by contact with the ground 10 .

The braking pad 150 may be coupled to the lower surface of the base plate 110 , more specifically, the vertical plate 112 through screw coupling or the like. Therefore, not only can the rigidity of the braking pad 150 be maintained when the kickboard is operated, but also when the damaged or worn braking pad 150 is to be replaced, the braking pad 150 detachably coupled to the base plate 110 . By releasing the coupling and coupling the new braking pad 150 , the replacement of the braking pad 150 can be easily performed.

For example, the braking pad 150 may be made of an elastic material (eg, rubber, etc.) in order to implement excellent braking force, but this is only an example for easy understanding of the present invention, so it may be used with other materials. It is also possible to manufacture the braking pad 150 .

As shown in FIGS. 2A and 2B , the brake device 100 including the base plate 110 , the foot pad 140 and the braking pad 150 is disposed in an elevated position in a normal state, where elastic coupling If the lifting arrangement is excessively performed by the elastic force acting from the means 120 , it may rather cause discomfort to the kickboard occupant.

To this end, according to a further embodiment of the present invention, a means for limiting the elevation of the brake device 100 at a predetermined position may be additionally provided. For example, the main scaffold 20 according to an embodiment of the present invention may further include a step portion 21 on its upper portion, and in a normal state, the brake device 100 is additionally provided by the step portion 21 . As the rise is restricted, the lifting position of the brake device 100 may be fixed at the lifting limit point.

The auxiliary scaffold 200 may be formed to protrude from the main scaffold 20 while accommodating at least a portion of the rear wheel 30 inside, for example, from the upper surface of the main scaffold 20 . The auxiliary footrest 200 is a structure in which the inner space is empty (ie, common), and the inner space is defined as the rotational space of the rear wheel 30 , so the height of the auxiliary footrest 200 is greater than the radius of the rear wheel 30 . Large and the width of the auxiliary footrest 200 may be greater than the thickness of the rear wheel (30).

The kickboard operator can mount one foot on the main scaffold 20 and the other foot on the auxiliary scaffold 200 while driving. In this way, two scaffolds having different heights are respectively disposed at the front and rear of the kickboard. (i) it is possible to hold the center of gravity with both feet, so that the driving stability of the kickboard can be further strengthened, and (ii) the auxiliary footrest 200 and the brake device 100 in a normal state are implemented so that they are almost at the same height. By doing so, braking can be implemented more easily and quickly while driving, and (iii) various kickboard stunts (e.g., front wheel lifting (Willie), steering wheel turning (baspin), power brake, etc.) can be more easily performed. By doing so, the user's interest in the kickboard device may be further increased.

As shown in Figure 2, the auxiliary footrest 200 according to an embodiment of the present invention may be composed of a center body 210 and the side body 220 of both sides thereof, the center body 210 is the front It may be composed of an inclined portion 211 and a footrest portion 212 .

The footrest unit 212 is an area on which the user's foot is mounted. Preferably, the ground 10, the main footrest 20, and the footrest unit 212 may be arranged parallel to each other for driving stability. In this regard, according to a further embodiment of the present invention, an inwardly recessed recess may be formed in at least a partial region of the footrest 212, and the formed recess may correspond to, for example, the shape of a foot, , the rear of the formed recess may be configured to substantially correspond to the height of the top of the foot pad 140 , and thus the driving stability of the kickboard operator may be further improved.

In addition, the front slope 211 extending downwardly from one end of the footrest unit 212 forward may be implemented as a straight slope as shown in FIG. 2 , but according to another embodiment of the present invention, the configuration of a curved slope, a right angle The configuration of the slope and the like may also be possible.

In addition, although FIG. 2 exemplarily shows a configuration in which the rear inclined portion of the auxiliary scaffold 200 is bent once, this is only an example for easy understanding of the present invention, and the rear of the scaffold 212 is The curved surface extending downward from the slanted surface may be implemented in various ways, such as a curved surface slope, a straight slope, and a streamlined slope, and the rear wheel 30 may rotate through the rear space of the footrest unit 212 formed in this way.

The auxiliary scaffold 200 according to an embodiment of the present invention may be fixedly coupled to at least a partial region of the main scaffold 20 , more specifically, to the rear body of the main scaffold 20 . For example, as shown in Figure 2a, according to an embodiment of the present invention, the coupling plate 230 of the auxiliary scaffold 200 is coupled to the main scaffold 20 through a coupling means (eg, screw coupling, etc.) may be coupled to at least a partial region of the upper surface of the .

Alternatively, according to a further embodiment of the present invention, as shown in FIG. 2e , the front end of the auxiliary scaffold 200 is connected to the center through-axis 22 of the main scaffold 20 at the rear side of the main scaffold 20 . It is also possible that the auxiliary scaffold 200 is coupled to the main scaffold 20 in such a way that the rear end of the auxiliary scaffold 200 is connected to the rear wheel shaft, where the auxiliary scaffold 200 and the main scaffold 20 are firmly coupled. For this, the lower end of the auxiliary scaffold 200 may be coupled by adding or replacing the screw coupling with the rear body (lower plate) of the main scaffold 20 . In this case, since the combination of the auxiliary scaffold 200 and the main scaffold 20 is implemented inside the main scaffold 20 that is not visually visible to the kickboard user, the aesthetics of the kickboard device can be further improved.

In addition, since the auxiliary scaffold 200 has an empty interior and has to support the weight of the operator, it is preferable to be made of a material with excellent strength, for example, to manufacture the auxiliary scaffold 200 with a material such as metal or reinforced plastic. can For reference, since materials such as metal and reinforced plastic generally correspond to opaque materials, the rear wheel 30 disposed inside the auxiliary scaffold 200 is not visually visible as shown in FIG. 2 . According to the user's need, the rear wheel 30 may be implemented to be visually confirmed through the auxiliary footrest 200, which will be described in more detail in FIG. 3 below.

As shown in FIGS. 2A and 2B , in a normal state, the brake device 100 and the auxiliary scaffold 200 are spaced apart from each other at a predetermined interval, and the kickboard operator puts their feet on the scaffold 212 of the auxiliary scaffold 200 . The timing and position to press the foot pad 140 of the brake device 100 may be grasped by sensing the separation space while moving the foot backward in a state in which the brake device is mounted.

Here, in order for the kickboard operator to more easily and accurately grasp the pressing timing and position of the foot pad 140 , the scaffold 212 of the auxiliary scaffold 200 according to an additional embodiment of the present invention has a protrusion 212a on the rear side. ) may be further provided, and such a configuration is exemplarily shown in FIG. 2C . As shown in FIG. 2C , a protrusion 212a may be formed at the rear end of the scaffold 212 , and the protrusion 212a may be provided with a height of about 1-4 mm, so that the operator By sensing both the protrusion 212a and the separation space while moving the foot backward while the foot is mounted on the foot 212, the timing and position to press the foot pad 140 of the brake device 100 can be more accurately and easily can be grasped

In addition, as described above, in the normal state, the rising position of the brake device 100 may be fixed at the rising limiting point by limiting the additional elevation of the brake device 100 by the step portion 21 . Another embodiment of the present invention According to an example, the step portion 21 may not be provided in the main scaffold 20 , and in this case, the brake device 100 is in a normal state by the auxiliary scaffold 200 , more specifically, after the auxiliary scaffold 200 . As additional elevation is restricted by grounding with the direction, the elevation position of the brake device 100 may be fixed at the elevation limiting point (for example, refer to the configuration shown in FIG. 2D ).

For reference, unlike the “C”-shaped base plate 110 shown in FIG. 2 , in another embodiment of the present invention, the shaft insertion hole 113 at the front end of the base plate 110 is replaced by a straight steel plate. A spring may be disposed in the shaft insertion hole 113 on the.

In addition, in FIG. 2 , the auxiliary footrest 200 is made of a non-transparent material, so that a partial region of the upper end of the rear wheel 30 may not be visually visible to the user. Depending on the kickboard users, there are many cases where lighting means such as LEDs are attached to the wheels and used for night driving, and some of these users may wish not to block such night lighting effects as much as possible. Therefore, according to a further embodiment of the present invention, the entire rear wheel 30 can be visually shown to the user without at least a part of the rear wheel 30 accommodated inside the auxiliary footrest 200 being shielded, such a configuration This is exemplarily shown in FIGS. 3A and 3B .

As shown in Figures 3a and 3b, the side body 220 of the auxiliary scaffold 200 according to an additional embodiment of the present invention may be additionally provided with a window (221, window) of various shapes, thus the user can visually confirm the rear wheel 30 disposed therein through the window 221 of the side body 220 .

Alternatively, as another embodiment of the present invention, as shown in Figure 3c, the side body 220 of the auxiliary scaffold 200 may be implemented in the shape of a minimized structure. In this case, the auxiliary footrest 200 may be configured as a center body 210 that is an upper surface forming the front inclined portion 211 and the footrest portion 212, and a leg supporting the center body 210, and accordingly, more It can be implemented as a strong material. Accordingly, the user can visually confirm the rear wheel 30 disposed therein in a wider area.

In addition, as shown in FIG. 3D , according to an additional embodiment of the present invention, the auxiliary footrest 200 may be made of a transparent material, and thus the user may use the rear wheel 30 disposed inside through the side body 200 . can be visually confirmed

More specifically, the base plate 110 according to the present invention includes a pair of parallel plates 111 forming an inner recessed space defined as a rotational space of the rear wheel 30 and the pair of parallel plates 111 . It may be composed of a vertical plate 112 that interconnects one end of the kickboard, so that the inner recessed space faces the front of the kickboard and the vertical plate 112 may be composed of a “C”-shaped plate facing the rear of the kickboard. For reference, in another embodiment of the present invention, both rear corners of the vertical plate 112 can be finished to be inclined, thereby preventing jamming during driving and further improving driving convenience as described above.

5A and 5B respectively show the configuration of the brake device 100 and the auxiliary footrest 200 when the kickboard is in a braking state according to an embodiment of the present invention. As shown in FIG. 5 , when the kickboard operator presses the brake device 100 , more specifically, the foot pad 140 , downward for braking, the brake device 100 moves downward and the base plate 110 . The lower part of the braking pad 150 coupled to the lower surface of the body comes into contact with the ground 10, and accordingly, a braking force for braking of the kickboard is generated.

Rather than braking the kickboard by directly limiting the rotation of the wheel, braking is implemented by lowering the brake device 100 to cause friction with the ground 10, thus significantly improving the stability of the kickboard as well as reducing the problem of wheel wear. can be solved In addition, by bringing the braking pad 150 into contact with the ground 10 from the rear side of the kickboard, the braking force is generated in a direction completely opposite to the driving direction of the kickboard, so that the repulsive force can be further increased, and accordingly, the braking performance is significantly can be strengthened

As described above, the braking pad 150 according to the embodiment of the present invention may be made of a material such as rubber, and thus the rubber may be worn during continuous braking. 110 , and thus the worn braking pad 150 can be easily replaced with a new braking pad 150 .

Here, according to an additional embodiment of the present invention, a wear indicator may be built to a predetermined depth inside the braking pad 150, and the wear indicator may be built to a predetermined depth at which the braking pad 150 is worn. The degree may correspond to an experimentally determined or determined depth that impairs the user's stability in driving the kickboard, and for example, the identification of the wear indicator may be further improved through the guidance display of the built-in wear indicator.

Therefore, when the wear indicator is visually seen on the bottom surface of the braking pad 150 while using the kickboard, it means that the braking pad 150 needs to be replaced, so the kickboard user can use the braking pad 150 according to the visual appearance of the wear indicator. It can be replaced, thereby improving both user convenience and stability of the kickboard.
