Description

[Revision according to Rule 26.01.08.2011] Roller Skating Rides

The present invention relates to a roller skating ride, and more particularly, to a roller skating ride having a link system mounted to a body having a steering device.

In general, roller skates have a structure in which a wheel is provided at a fixing portion for fixing a foot, and can run quickly. The fixing part is usually in the form of shoes, and may be classified into inline skates and ordinary roller skates depending on whether the wheels are in a row or a row in the front-rear direction.

By the way, in the conventional roller skates, the wheels are provided in a size and an arrangement that do not significantly deviate from the width of the fixing portion, so that they fall easily back and forth. And it is not equipped with a brake that can prevent the operation of the wheel. Of course, the friction portion that causes friction with the ground in front of or behind the fixing portion is provided to suppress the running state, but in this case, the wheel can be freely rotated. Therefore, it is impossible to move up the hill while the conventional roller skates are mounted on the feet.

On the other hand, the conventional bicycle is provided with a pair of wheels in the front and rear direction, so that the brakes do not fall back and forth, and the brake can fundamentally prevent the operation of the wheels, thereby preventing the phenomenon of being easily stopped or pushed back during hill climbing. It is possible to easily change the direction of the steering device is provided.

However, the bicycle is easy to fall from side to side, due to the size of the wheel and the size of the frame is bulky and heavy, there is an inconvenience that the user has to push down when climbing hills.

The conventional three-wheeled kickboard is steered by the front wheels and gains propulsion while moving the wheels provided on both side kickboards connected to the front wheel shafts to the left and right feet. Among these three-wheeled kickboards, fixed kickboards with constant angles between the left and right kickboards with respect to the front axle and variable kickboards that can be moved up and down between the left and right kickboards are available on the market. The disadvantage is that the driving force is weak. On the other hand, in the case of the variable kickboard, it may be considered that the left and right kickboards move independently of each other based on the front wheel shaft, but in this case, when the user performs the skating exercise, Since the position of the front wheels must be repeatedly moved from "left-> front-> right-> front" by the distance to the radius of the footrest, the user can maintain a stable skating motion while maintaining a constant direction and center. none.

The present invention is to solve the problems of the prior art, the volume is small and light, can be easily and quickly run, do not fall back and forth, left and right, can be easily stopped by the brake, the steering wheel can be switched, To provide a roller skating ride that can be easily climbed using a brake even when climbing hills.

The roller skating ride mechanism of the present invention includes a body having a steering device, a link system rotatably mounted on a reference link provided in the body and expanded in a horizontal direction, and rotatably connected to the link system through a longitudinal link . the stay, and in that characterized in that the skate includes a portion having a wheel which rotates while being in contact with the government, when securing the foot.

Here, the link system includes an intermediate link for pivotally connecting a plurality of arms at an intermediate portion of each other, a tip link for pivotally connecting the ends of each adjacent arm, and a rear end of each adjacent arm. It may also consist of a rear link that connects one another with rotation.

The reference link is preferably rotatably connected to a center located in the left and right directions of the intermediate link or the rear link.

On the other hand, it is preferable that the brake is mounted to block the operation of the wheel.

In addition, between the link system and the skate portion, it is preferable that a connecting portion for enabling the relative movement of the skate portion relative to the link system.

In addition, the body is preferably provided with an auxiliary wheel that receives the load applied to the reference link.

In addition, a spring is preferably installed between the body front end side and the center front end side of the link system.

According to the roller skating riding mechanism of the present invention, it is smaller and lighter than a bicycle, and can run easily and quickly without falling from side to side like a roller skate, does not fall back and forth like a bicycle, can be easily stopped by a brake, and handles You can change directions, and you can easily walk up the hill with your brakes.

Hereinafter, the roller skating riding mechanism of the present invention will be described in more detail with reference to the accompanying drawings.

1 is a side view of a roller skating riding mechanism of the present invention. Fig. 2 is a top view of the roller skating ride mechanism of the present invention, in which the handle and the handle shaft are shown in dotted lines, (a) the link system faces the front, and (b) the link system faces the right side. .

As shown, the roller skating ride mechanism 100 of the present invention, the body 30 having a steering device, and is rotatably mounted to the reference link (lr) provided in the body 30 is stretched in the horizontal direction A linking system 40 which is connected to the linking system 40 via the end link ls, which is rotatably connected to the linking system 40 , and a skating wheel 51 which rotates while contacting the ground. It characterized in that it comprises a skate unit 50 having a) .

The steering device needs to have a similar function and form to that provided in a conventional kickboard. Therefore, the front wheel 11 may be provided at the handle 10 and the handle shaft 12. In the example shown here, the handle shaft 12 is an example connected to the body 30 through the intermediate member 20, the intermediate member 20 may be provided integrally to the body 30, of course.

The body 30 may also have a function and a shape similar to those provided in the conventional kickboard. It does not have to be wide because it is not intended to place the foot.

The reference link lr is provided in a part of the body 30. When the link system 40 is retracted, that is, when the skate part 50 approaches the left and right innermost, the front end side of the link system 40 is the intermediate member 20 or the handle shaft ( 12) should be a position that will not interfere with. Of course, when the spring 21 is provided as described later, the position may be adjusted in consideration of the elastic action force.

The link system 40 refers to a mechanical system made up of a plurality of links and a plurality of arms connected thereto so as to be able to stretch left and right inside and outside. As described below, a plurality of X-shaped links may be configured to be connected to each other, or a known link system that is stretched and contracted in the horizontal direction. Here, the horizontal stretching means that almost no movement occurs in the vertical direction and most of the movement is performed only in the horizontal direction when ignoring the elastic twisting of each arm that is a component of the link system. Of course, there may be some vertical motion in reality, but it means that the effect is assumed to be negligible.

The skate unit 50 may have a size and a function substantially similar to those of a conventional roller skate. However, the difference is that a part of it is connected to the link system 40.

The skating wheel 51 may have a size and a function substantially similar to those of a conventional roller skate as a part that enables rolling motion. However, it is preferable that a brake (not shown) is installed to block the operation of the skating wheel 51. The handle 13 of the brake is conveniently provided in a part of the handle 10.

The fixing part 52 is a part for fixing the user's foot, and is shown in the form similar to the fixing part of the slipper to put shoes or feet, but is not limited to this, put the shoes or feet into a strap or magic fastener It may be in the form of fixing, or may be in the form of mechanical binding such as ski boots.

Hereinafter, specific examples of the link system will be described.

As shown in Figures 2 to 4, the link system 40, the intermediate link (lm) for rotatably connecting a plurality of arms (a) in the middle of each other, and each of the adjacent arms (a) ) it may also consist of the trailing link (lb) of the leading end link (lf) for rotatably connecting the front end with each other, rotatably connected to the rear end of the arm with each other (a) of the respective adjacent. That is, it can consist of multiple sets of X-shaped links. In this case, the skate unit 50 is connected to the outer arm. FIGS. 2 and 3 show four arms (a), and FIG. 4 (a) shows eight arms. 14 cases are shown. Of course, as shown, the length of the arm connected to the middle portion of the outermost arm of the arm is about half the length of the other arm, it is natural that the portion protruding to the outside may be deleted.

The link system 40 is connected to the reference link (lr) of the body 30 may be various. In this case, in particular, considering the front-rear direction length when the link system 40 is folded, the reference link lr is located at the center in the left-right direction among the middle link lm or the rear end link lb. It is preferred to be rotatably connected to the position. An example in which the reference link lr is connected to the rear end link lb is as shown in FIGS. 2, 3 and 4 (a), and an example in which the reference link is connected to the intermediate link lm is as shown in FIG. 4 (b). This may be classified according to whether the total number of intermediate links lm or trailing links lb is odd or even.

In this way, since the reference link lr is connected to the middle link (lm) or the rear end link (lb) of the link system 40 is located in the center in the left and right, the two side skating portion 50 is always symmetrical Exercise in a state. In addition, when the front and rear mounting positions of the two side skate portions 50 are the same position as the front and rear mounting positions of the reference link lr, the two side skate portions 50 are moved at any opening angle and any rotation angle. Even if the reference link (lr) is always maintained at the center position of the two skates (50). This allows the user to always predict the position of the center of the body with respect to the reference link lr of the body 30, so that a more stable skating, and also the handle 10 is connected to the body 30 and The distance between the bodies can also be kept substantially constant or predictable, so that even when the skate 10 is held by the handle 10, there is almost no change in the front, rear, left and right distances, which enables safer skating. Of course, as shown in Fig. 3 (c), the shape of the outermost arm or the shape of the connecting portion described later may be modified to increase the closeness between the skating portion 50 and the reference link lr.

Between the link system 40 and the skate unit 50, it is preferable that a connecting portion (fx) for enabling the relative movement of the skate unit 50 relative to the link system 40 is provided. The connection part fx is more smoothly skating, such as ankle or back kick, considering that the link system 40 can only stretch in the horizontal direction and the vertical displacement is relatively small or difficult. It is a kind of joint provided in order to. The configuration of the connecting portion fx is, for example, elastic in nature, and may be composed of a piece having rigidity in the horizontal direction. That is, a material having elasticity in the vertical direction as shown in Fig. 5 (c) and having a torsional elasticity as shown in Fig. 5 (d) can be considered. As another example, as shown in FIG. 5 (e), a universal joint or another biaxial joint (eg, a rotary link capable of rotating in an axial direction and a joint capable of rotating up and down) may be used.

The connection part fx and the skate part 50 are rotatably connected through the end link ls, so that the skate part 50 can be freely rotated in the horizontal direction. In addition, the termination link (ls) may be installed in a cylindrical member that connects the scaffold and the skating wheel 51 of the skate unit 50, that is, the scaffold and the skating wheel 51 up and down.

On the other hand, as shown, the body 30, it is preferable that the auxiliary wheel 31 receives a load applied to the reference link (lr) side. This is because if the auxiliary wheel 31 supports most of the load of the body 30 and the link system 40, the user can perform a lighter skating movement. That is, the auxiliary wheel 31 solves the problem that the user has to lift up to the body 30 together when lifting the foot extended to the rear during the skating exercise and put it forward.

In addition, the bottom height of the auxiliary wheel 31 is preferably manufactured to be located slightly below the line connecting the bottom surface of both skating wheels (51). If the auxiliary wheel 31 is lower than the line connecting the skating wheel 51, when the user moves the weight to the front foot and lifts the rear foot, the link system 40 is slightly inclined and the rear skating wheel 51 Since it is lifted slightly upward from the ground, the user can lightly lift the rear foot and move forward without being affected by the load of the link system 40 and the skate unit 50 or the ground friction. On the other hand, even if the auxiliary wheel 31 is slightly lower, when the user moves the rear foot forward and evenly puts weight on both feet, the linkage (fx) of the link system 40 slightly bends downward or rotates up and down. Since the skating wheel 51 all touches the ground, there is no inconvenience in skating.

In addition, it is preferable to install a vertical spring device (not shown) above the auxiliary wheel 31. As a result, when the weight is evenly applied to both skates 50, the vertical spring is compressed so that both skating wheels 51 touch the ground. On the contrary, when the weight is biased only on one skate, the vertical spring is elastic. By restoring the skating wheel 51 of the skate portion, which does not carry the weight while being restored, the skating wheel 51 may be slightly lifted from the ground.

In addition, a spring 21 is preferably installed between the front end side of the body 30 and the center front end side of the link system 40. The spring 21 applies a biasing force to direct the link system 40 to the front. As shown in FIG. 2 (a) or 2 (b), the front end of the link system 40, for example, the front end link (lf) ) And the front end side of the body 30, for example, the intermediate member 20. Thus, by forcing the link system 40 to face forward, as shown in Fig. 2 (b) by the elastic tension of the spring when the link system 40 moves to the side as shown in Fig. 2 (a) easily Backwards to the front, at this time, the body having a steering device 30 is subjected to the driving force forward forward by the length of the body 30 than the user's forefoot position, so as to help make skating easier Can be.

Therefore, the user may operate by using the skate unit 50 in a general skating operation. The central position between the two skates 50 is always approximately constant from the reference link lr and the handle 10, and increases the predictability of the user to ensure safe and comfortable use. And the fall of the front and rear direction is prevented by the body 30 and the front wheel 11, the change of direction is easily made by the handle 10 and the front wheel 11, the skating wheel of the skate unit 50 ( By operating the brake (not shown) acting on the 51 and the front wheel 11 with the brake knob 13, it is possible to easily ascend as if walking up even when climbing hills, for example.

As mentioned above, although this invention was demonstrated according to the specific Example, this invention is not limited to this. For example, two front wheels 11 or several auxiliary wheels 31 may be considered. In addition, it may be possible to fold by making a joint between the handle shaft 12 and the body 30. It should be understood by those skilled in the art that modifications, changes, and improvements within the scope of identity within the scope of other claims should be interpreted to belong to the present invention.

The present invention can be used in the production, use, research, test industry and sports, sports industry using the roller skate having a fall prevention function.
