Description

  The present invention relates to a kind of in-line skate, and in particular, includes a first roller that rotates in one direction, and the first roller is arranged in a suspended state with respect to the ground contact surface of the other roller, so that a good braking force can be obtained. The present invention relates to an inline skate that has a function and a forward application point, provides good safety, and conforms to human engineering.

  Well-known inline skate shoes come in five types: leisure, figure, field, technical, and speed. Of these, inline skate shoes for field, technical and speed are used for special places and applications, all of which are special and long-lasting. Can be used reasonably by use training. In addition, its structure and function are the same as those of leisure inline skate shoes, and therefore description thereof will be omitted. The following will discuss and explain leisure and figure inline skates.

  FIG. 7 shows a known leisure inline skate, which comprises a boot 1, a bottom seat 4 and a roller 3. Four to six rollers 3 are installed on the bottom seat 4, and each roller 3 can rotate in two directions, forward and backward, and both are located at the same altitude and simultaneously contact the ground. In addition, the known figure inline skate shown in FIG. 8 is provided with a rubber braking head 2 at the position of the first roller of the leisure inline skate, and all other rollers are reduced so that the braking head 2 It is arranged at the rear.

  The known figure inline skates described above (see FIG. 8), when it is necessary to slide with the left foot, press the ground with the rubber braking head 2 of the right foot to provide forward thrust to the left foot and the opposite The same applies to the case. However, since all the rollers are arranged close to the rear, the pitch between all the rollers is shortened, and the sliding with the inline skates becomes slow and unstable. This is the first drawback. In addition, when accelerating forward sliding, the center of gravity of one foot must be tilted forward. At this time, if the braking head 2 touches the ground, the skater may fall forward, which is well known. This is the second drawback of the inline skates for figure.

  In addition, since the leisure inline skate shown in FIG. 7 does not have the braking head 2, when the left foot is desired to slide forward, the ground must be pressed slightly after being slightly biased with respect to the sliding direction of the right foot. , Can not provide the force to advance the left foot, violates human engineering. This is a drawback of leisure inline skates. In addition, since a known leisure-type inline skate cannot provide an effective braking arrangement, a certain manufacturer provides a structure in which a braking head 5 is arranged behind a roller. However, this design cannot provide a braking effect unless the soles are lifted with an unreasonable force when sliding, and it does not conform to ergonomics, and the structure of the braking head 5 is when the foot is slipped or bent. The two feet rub against each other and cause a fall. A special technique is T-braking on both sides of the foot, that is, both sides are suddenly opened while sliding, and both feet and the skating direction are 90 degrees to obtain a braking function. However, this technique is effective only after a long practice, and there is a risk of inadvertently falling down and spraining the hips and legs, which does not match human engineering. Moreover, it cannot be carried out in all places, and it is easy to cause a fall in a place where it is difficult to slide or has unevenness, which is the second drawback of such a leisure-type inline skates.

  The present invention aims to provide a kind of in-line skate, which solves the above-mentioned known drawbacks, which comprises a first roller which can rotate in only one direction, which is the ground plane of the other roller. Or the size of the first roller is made smaller than the other rollers to form a suspended shape, and the first roller is at least one of the front or rear of the plurality of rollers of the inline skates. When placed forward, it provides a braking or forward force application point, and when placed rearward, provides a forward deceleration device or a backward sliding application point, It shall be an inline skate that has a forward application force, conforms to human engineering, and has good safety.

  In order to achieve the above-mentioned object, the in-line skate of the present invention includes a first roller, and the first roller is disposed so as to be suspended from the ground contact surface of the other roller, and the first roller is Rotating in only one direction, when the first roller is arranged forward, the first roller rotates unidirectional forward, and when the first roller is arranged rearward, the first roller is backwards It rotates in one direction.

  In the in-line skate, when the first roller is disposed in front of the in-line skate, the first roller rotates forward only in one direction, and the first roller is suspended from the ground contact surface of the other roller. It has a function of ground force and frictional force because it cannot rotate backward, and when the user wears inline skates and slides forward, the first roller is tilted forward by ergonomics. Since the first roller cannot rotate backward when it naturally contacts the ground and is applied backward, it forms a frictional resistance with the ground, so that the user can be quickly propelled forward.

  Next, the force applied by the tip of the foot and pushing backward is the same as the forward direction, which is different from pushing one of the known feet diagonally backwards, and therefore the force is dispersed. The power source can be used effectively and is compatible with human body engineering.

  Further, when the first roller of the in-line skate is provided behind the other rollers of the in-line skate, the first roller can be rotated unidirectionally only in the rear direction, and the first roller is a grounding surface of the other roller. When the user slips forward and needs to be decelerated or braked, the first roller will naturally contact the ground simply by lifting the sole, but the first roller will only face backwards The first roller naturally forms friction with the ground because it can rotate and does not rotate forward, thereby producing deceleration and braking effects.

  Furthermore, the design of the present invention is elaborate, and its function combines the advantages of the well-known leisure and figure inline skates. When the first roller is used for braking, the general four-wheel roller skates and ice skates Similarly, the operation of various well-known figure inline skates can be completed easily. When moving forward, there is no problem with the braking head, so there are no disadvantages of the known leisure and figure inline skate shoes, which is superior to the known leisure and figure inline skate shoes.

The invention of claim 1 is an inline skate having a boot, a bottom seat, and a plurality of rollers arranged on the same straight line.

The invention according to claim 8 is the inline skates according to claim 1, wherein the first roller is located behind the plurality of rollers.
A ninth aspect of the invention is the inline skate according to the eighth aspect of the invention, wherein the first roller is capable of rotating in a single direction only backward.
A tenth aspect of the present invention is the inline skates according to the first aspect, wherein a plurality of granules or rough surfaces are provided on the surface of the first roller.

  The in-line skate of the present invention includes a first roller, the first roller is rotatable in one direction, and the arrangement thereof is suspended with respect to the ground contact surface of the other roller, and the first roller is the other roller. When the first roller is disposed forward of the first roller, the first roller rotates unidirectionally forward, and when the first roller is disposed behind the other rollers, the first roller rotates backward unidirectionally. It is equipped with a braking function for dredging forces and a forward application point, providing good safety and conforming to human engineering.

  As shown in FIG. 1, the inline skate of the present invention includes a boot 1, a bottom seat 4, and a plurality of rollers 3.

  The feature of the present invention is that the arrangement of the first roller 31 of the front bridge of the inline skates is suspended with respect to the ground contact surface of the plurality of rollers 3, and the first roller 31 rotates unidirectionally only forwardly. is there.

  Among them, the unidirectional rotation mechanism of the first roller 31 is a unidirectional bearing (FIG. 5), a unidirectional ratchet structure (FIG. 6), a unidirectional clutch (FIG. 4), or other unidirectional rotation mechanism having the same effect. The

  Please refer to FIG. 1, FIG. 2 and FIG. FIG. 2 shows a centroid line 10 of a general person. When the human body moves forward, the movement line 20 of the centroid reaches from the centroid point 22 to the centroid point 24 and finally to the centroid point 26. When the user wears in-line skate shoes and slides forward, when the application point is necessary, the center of gravity of the human body tilts forward and the center of gravity moves to the center of gravity point 26. When contacting and further pushing back, the reaction force direction 34 and the unidirectional rotation direction 32 of the first roller 31 are opposite, and therefore the first roller 31 is not rotatable. The first roller 31 cannot rotate rearward and the frictional force generated with the ground) is completely transmitted to the user's body, thereby promptly propelling the user forward. When the user slides forward, the first roller 31 rotates forward when the first roller 31 touches the unevenness of the ground or the ground, and thus does not affect the forward slip. Therefore, the present invention provides a good forward application force and does not have the disadvantage of being stumbling like the well-known figure-type inline skate, which is compatible with ergonomics.

  Also, when sliding backward, the center of gravity of the person naturally moves backward, and the first roller 31 of the present invention is in a suspended state with respect to the ground contact surface of the plurality of rear rollers 3 (distance X in FIG. 1). ), The first roller 31 rotating only forward does not affect the slip, and even when performing a figure motion, the first roller 31 that rotates unidirectionally can be used to form a braking and fixed point function. Various figure movements can be performed.

  As shown in FIG. 3, the present invention provides a point of application when sliding forward, to the user's forward sliding. Further, when braking is required when the user slides forward, the user rotates and slides backward, and then when the user stands up, the center of gravity moves forward and the first roller 31 moves to the ground. The first roller 31 is rubbed against the ground by using a unidirectional rotation mechanism of the first roller 31, thereby obtaining a braking effect.

  See FIG. If the first roller 31 is provided behind the plurality of rollers 3 and the ground and the ground have a distance Y as shown in the figure, when the user is sliding forward, it is only necessary to decelerate or brake. If the back is raised, the first roller 31 naturally contacts the ground, and the first roller 31 rotates only backward and cannot rotate forward. Therefore, the first roller 31 forms friction with the ground and thereby decelerates. And the braking effect can be obtained. When sliding backward, the user's center of gravity moves backward and the weight acts on the rubber roller, so the first roller 31 naturally contacts the ground, and the first roller 31 can only rotate backward, so the first The roller 31 also has a function of rotating backward. At this time, the first roller 31 is used for backward unidirectional rotation. Of course, the first roller 31 can be provided at the same time in front of and behind the plurality of rollers, and the surface of the first roller 31 is provided with a plurality of granules or a rough surface, so that the frictional force with the ground is provided. Can be increased.

  Please refer to FIG. 3 and FIG. 10 together. The situation where a user falls is divided into a forward fall and a backward fall. In a forward fall, the center of gravity of the person tilts forward, and the speed at which the foot advances cannot catch up with the speed of advancement of the person's body, so the body turns forward and the foot falls behind. When the first roller 31 of the present invention is provided in front of the plurality of rollers 3, when the center of gravity tilts forward, the first roller 31 comes into contact with the ground, and the above-described force point mechanism causes the foot to slide backward. To prevent it from falling forward. In addition, when the body falls back, the center of gravity of the person moves backward, and the body advances at a speed that is backward regardless of the speed at which the foot advances. When the first roller 31 of the present invention is provided behind the plurality of rollers 3 and the center of gravity moves backward, the first roller 31 comes into contact with the ground and the foot slides forward due to the above-mentioned mechanism of the application point. It can prevent it from falling backwards. The in-line skates of the present invention can prevent a beginner from losing control and falling because the body or feet slide too forward or backward.

  Therefore, the in-line skate of the present invention provides a unidirectional rotating structure technology, and by means of human body engineering, the rotating parts are provided with both rotational march and braking functions according to the positions of the skillfully arranged parts. As the movement progresses, the rotating parts automatically have the timely skating and braking function, especially the first roller provides an auxiliary function to prevent inadvertent falls, and thus many disadvantages of inline skate shoes The braking function is increased by improving the above, conforming to human body engineering, and has an unprecedented automatic assist function for preventing falling.

  In summary, the in-line skate of the present invention includes the first roller 31, the first roller 31 can only rotate in one direction, is disposed so as to be suspended from the ground contact surface of the other roller 3, and One roller 31 is arranged in front of or behind the other rollers, whereby the braking function is increased to prevent overturning, and an inline skate that conforms to human body engineering is obtained.
