Abstract
A skate includes a ring-shaped wheel rim (1), in inner side of which a ring-shaped track (5) is provided and extends along the circumferential direction of the wheel rim; a wheel carrier provided in the inner side of the wheel rim; rollers (41, 42) located on the wheel carrier and rolling on the ring-shaped track (5); a pedal (3) provided on the wheel carrier. So the skate with such structure can decrease the height of the pedal, and eliminate the limit that the diameter of the wheel rim cannot be increased because of the limit of torque effected on the feet. Therefore, the diameter of the wheel rim of the skate can be much larger than the diameter of the sliding wheel of the prior skate, and thus the skate has the stronger performance of crossing the vertical wall.
Description
- The present relates to a rolling walking device, more particularly, to a skate.
- Most of the conventional states are provided with an arrangement of multiple rollers. For example, double-row and four-wheel skates are adopted in order to increase the lateral stability of skates, while single-row and multi-wheel skates are adopted in order to increase the vertical smooth transition capability. At present, in order to enhance the performance of crossing a vertical wall of the skaters, it is needed to increase diameter of sliding wheels. However, since the sliding wheels of the skate are usually mounted below a pedal, an increase in the diameter of the sliding wheels will definitely lead to an increase in the height of the pedal, while torque force effected on human feet will be increased thereafter due to the increase in the height of the pedal, thus a risk of foot sprain is increased correspondingly. Besides, during crossing the vertical wall, the front and rear wheels of the skate climb over the obstacle at a same height successively. In this case, a second impact force applied to the rear wheels of the skate by the obstacle is equal to that applied to the front wheels, thus resulting in too many impact cycles. Moreover, the impact force is too large when the skate crosses the vertical wall since the increase in the height of the wheel is limited.
- An objective of the present invention is to provide a skate having strong performance of crossing a vertical wall, aiming at the drawback that the performance of crossing a vertical wall for the conventional skate is relatively poor.
- The technical solution for achieving the objective of the present invention is as follows: a skate is provided, comprising:
- a ring shaped wheel rim, on an inner side of which a ring-shaped track is provided and extends along a circumferential direction of the wheel rim;
- a wheel carrier provided in the inner side of the wheel rim;
- rollers located on the wheel carrier and rolling on the ring-shaped track; and
- a pedal provided on the wheel carrier. In the skate of the present invention, the wheel carrier includes a ring-shaped part, on periphery of which the rollers are arranged.
- In the skate of the present invention, the wheel carrier at least comprises an upper part and a lower part connected with each other through a support, and both of the upper part and the lower part are provided with an arc part adapting the ring-shaped track respectively, wherein the rollers are arranged on the arc parts.
- In the skate of the present invention, the skate further comprises a foot blocking member including a blocking part for semi-enclosing the wheel rim and a connecting part connecting with the blocking part, and the connecting part is fastened on the wheel carrier.
- In the skate of the present invention, the rollers comprise vertical rollers axes of which are in parallel with that of the wheel rim.
- In the skate of the present invention, the rollers further comprise lateral rollers axes of which are perpendicular to that of the wheel rim.
- In the skate of the present invention, the wheel carrier is provided with a sub-wheel carrier that extends towards a rear direction of the wheel rim and is provided with sub-wheels.
- In the skate of the present invention, the wheel carrier has two sub-wheel carriers that are arranged on both sides of the wheel carrier respectively, wherein each of the two sub-wheel carriers is provided with a sub-wheel.
- In the skate of the present invention, the sub-wheels are tilting relative to the vertical direction.
- In the skate of the present invention, the wheel rim and the sub-wheels are provided with a tire or a rubber tape.
- When implementing the skate of the present invention, the following advantageous effects can be achieved: in the skate of the present invention, the inner side of the wheel rim is provided with the ring-shaped track and the wheel carrier, the rollers on the wheel carrier can roll on the ring-shaped track, and the pedal is arranged on the wheel carrier. Such structure can lower height of the pedal and eliminate the limit that the diameter of the wheel rim cannot be increased because of the limit of the torque effected on the human feet. Therefore, the diameter of the wheel rim of the skate in the present invention can be much larger than that of the sliding wheel of the conventional skates, thus making the skate have stronger performance of crossing the vertical wall.

- As shown in
FIG. 1 andFIG. 2 , a first embodiment of the skate in the present invention is illustrated. This embodiment is a single-wheel skate, comprising a ring-shaped wheel rim 1, a ring-shaped track 5 which is provided on an inner side of thewheel rim 1 and extends along a circumferential direction of thewheel rim 1, and a wheel carrier provided in the inner side of thewheel rim 1. In the embodiment, the wheel carrier comprises alower part 21 and anupper part 22, the twoparts support 72. In the embodiment, thesupport 72 is a portion of afoot blocking member 7. Since thelower part 21 and theupper part 22 of the wheel carrier have a same structure, such structure is discussed by taking thelower part 21 for example in the following. As shown in the figures, thelower part 21 has an arc part adapting to the ring-shaped track 5, and multiple rollers are arranged on the arc part. The multiple rollers includevertical rollers 41 axes of which are in parallel with that of thewheel rim 1, and lateral rollers axes of which are perpendicular to that of thewheel rim 1. Thevertical rollers 41 are used for load bearing, while the lateral rollers are used for reducing friction force between thelower part 21 and the side of the ring-shaped track 5. Apedal 3 of the skate for foot treading by a glider is arranged on thelower part 21 of the wheel carrier. In the embodiment, the skate further includes afoot blocking member 7 so as to prevent thewheel rim 1 from rubbing the glider during rolling. Thefoot blocking member 7 is comprised of a blockingpart 71 for semi-enclosing thewheel rim 1 and a connecting part for fixing thefoot blocking member 7 onto the wheel carrier, wherein the connecting part is just thesupport 72 in the present embodiment. It should be understood that thelower part 21 and theupper part 22 of the wheel carrier in the present embodiment can also be connected together through a separate support, and then the connecting part of thefoot blocking member 7 is fastened on the support or theupper part 22 directly. During usage of the skate, thewheel rim 1 rolls on the floor and the wheel carrier rolls in thewheel rim 1 relative to thewheel rim 1. - As shown in
FIG. 3 toFIG. 6 , a second embodiment of the skate in the present invention is illustrated. This embodiment is a composite-wheel skate with sub-wheels, wherein a mother wheel has a same structure as that of the single-wheel skate in the first embodiment. Referring toFIG. 1 andFIG. 2 , the mother wheel comprises a ring-shaped wheel rim 1, a ring-shaped track 5 which is provided on the inner side of thewheel rim 1 and extends along the circumferential direction of thewheel rim 1, and a wheel carrier provided in the inner side of thewheel rim 1. In the embodiment, the wheel carrier comprises alower part 21 and anupper part 22, the twoparts support 72. In the embodiment, thesupport 72 is a portion of afoot blocking member 7. Since thelower part 21 and theupper part 22 of the wheel carrier have a same structure, such structure is discussed by taking thelower part 21 for example in the following. As shown in the figures, thelower part 21 has an arc part adapting to the ring-shaped track 5, and multiple rollers are arranged on the arc part. The multiple rollers includevertical rollers 41 axes of which are in parallel with that of thewheel rim 1, and lateral rollers axes of which are perpendicular to that of thewheel rim 1. Thevertical rollers 41 are used for load bearing, while the lateral rollers are used for reducing friction force between thelower part 21 and the side of the ring-shaped track 5. Apedal 3 of the skate for foot treading by a glider is arranged on thelower part 21 of the wheel carrier. In the embodiment, the skate further includes afoot blocking member 7 so as to prevent thewheel rim 1 from rubbing the glider during rolling. Thefoot blocking member 7 is comprised of a blockingpart 71 for semi-enclosing thewheel rim 1 and a connecting part for fixing thefoot blocking member 7 onto the wheel carrier, wherein the connecting part is just thesupport 72 in the present embodiment. In the present embodiment, additional sub-wheels are employed for the skate so as to reduce a secondary impact force by an obstacle applied on the skate. Specifically, twosub-wheel carriers wheel rim 1 are arranged on both sides of thewheel carrier 21. Two sub-wheels 61 and 62 are respectively arranged on thesub-wheel carrier wheel rim 1 is located at the anterior corresponding to thepedal 3, while touchdown points of the sub-wheels 61 and 62 are close to a central line of thewheel rim 1. Besides, side projections of the sub-wheels 61 and 62 intersect with that of the wheel rim 1 (referring toFIG. 4 andFIG. 6 ). - It can be seen from the above-mentioned embodiments that in the skate of the present invention, the wheel carrier equipped with the rollers is fixed in the inner side of the
wheel rim 1 in an embedded manner so that the rollers can roll on the ring-shapedtrack 5 on the inner side of thewheel rim 1. Besides, a traditional touchdown sliding wheel lower than thepedal 3 is replaced by atouchdown wheel rim 1 higher than thepedal 3, thus the performance of crossing a vertical wall for the skate is enhanced doubly. Weight of the skate can be controlled in a reasonable range due to the adoption of the wheel rim without any spoke and wheel axle. Since the sub-wheels are arranged tilting to each other, the side projections of the wheel trims intersect without interfering with each other. In this way, when climbing over a higher vertical obstacle, the relay interval between the front and rear wheels is shortened because the rear wheels no longer climb over the obstacle from its lowest level. That is, the intersection of the side projections of the wheel trims can reduce and restrict the secondary impact by the obstacle on the rear wheel effectively so as to realize a smoother and more comfortable sliding. - In the present invention, by utilizing multiple structural forms of the wheel rim and the embedded wheel carrier, skates with different structures can be manufactured, wherein the diameter of the wheel rim is higher than the pedal, and the performance of crossing vertical walls is enhanced without raising the centre of gravity. Moreover, the single-wheel structure can eliminate the secondary impact of the obstacle on the rear wheel in vertical direction thoroughly.
- In the above-mentioned two embodiments of the present invention, a section of the ring-shaped track of the wheel rim is U-shaped. However, it should be understood that the ring-shaped track on the inner side of the wheel rim can has any suitable sectional shape. For example, the section of the ring-shaped track on the inner side of the wheel rim can be a concave section for guiding the rolling of the vertical rollers, or also a convex section for guiding the rolling of H-shaped rollers, or also a V-shaped section for guiding the rolling of tilted and vertical rollers, or any other section shapes suitable for lateral stability and vertical rolling.
- The rollers on the wheel carrier roll on the ring-shaped track on the inner side of the wheel rim. The rollers can be composed of vertical rollers simply or a combination of vertical and lateral rollers. The wheel carrier can be connected and fastened with shoes directly, in which case the centre of gravity for the wheel carrier should be as close to the rear part of the wheel rim and the longitudinal centerline as possible. The wheel carrier can also be connected with the pedal. In addition, the wheel carrier can be paired components up and down which are connected with each other by the foot blocking member, or may be one single component, or may be a ring-shaped component embedded in the wheel rim. The wheel carrier or the pedal can extend towards the rear direction along both sides of the wheel rim to act as a support for the sub-wheels, on which a plurality of sub-wheels can be mounted. The sub-wheels can be mounted in a bilateral symmetrical or staggered manner and tilted with each other in an angle of elevation. The touchdown points of the sub-wheels should be as close to each other as possible. The wheel trim of the sub-wheel can intersect with the side projections of the front wheel rim and other sub-wheels without interfering with each other. The touchdown points of the sub-wheels should be at the same longitudinal direction as that of the wheel rim as possible. The sub-wheels can be tilted in an angle of elevation and bilateral symmetrical behind the wheel rim. Moreover, a rear sub-wheel can be located in a central seam position of two front sub-wheels, in such a case the wheel trim of the rear sub-wheel intersects with the side projections of the front sub-wheels. The sub-wheels can be adjusted to be off the ground slightly according to actual requirements. In the case of multiple sub-wheels, the sub-wheels can be mounted in a bilateral opposite or staggered manner tilting to each other behind the wheel rim, while the side projections of the sub-wheels intersect without interfering with each other. In the skate of the present invention, the foot blocking member can be in a shape of strip, semi-enclosed wheel rim or ring-shaped semi-enclosure, or any other shapes being beneficial to beauty.
- Although the embodiments of the present invention are described with reference to the accompanying drawings above, the present invention should not be limited to the above-mentioned specific implementations, which are only for the purpose of example instead of limitation. Without departing from the objective of the present invention and the scope of protection protected by claims, many forms can be made by persons having ordinary skills in the art in the inspiration of the present invention. All these forms should be included in the scope of protection of the present invention.
