Abstract
A skateboard wheel mount comprises a base, an axle, and a torsion spring. The base is formed of a front plate and a rear plate and is fastened with the underside of a deck of the skateboard such that the front plate and the deck form a predetermined angle. The front plate is provided with a stop piece extending therefrom. The axle is pivoted by a spindle between the front plate and the rear plate and is provided with an urging piece extending therefrom such that the urging piece is located under the stop piece. The torsion spring is fitted over the front segment of the spindle for cushioning the wheel mount and for correcting the direction in which the axle turns.
Description
- The present invention relates generally to a skateboard or the like, and more particularly to a wheel mount of the skateboard or the like.
- The conventional skateboard wheels are mounted on an axle which is pivotally fastened with a base by a pivot, without the use of cushions. As a result, the component parts are susceptible to wear which is brought about by friction. In addition, the skateboard can not be easily maneuvered by the rider when the skateboard is cruised on a bumpy surface, especially on the occasion that the axle is turned excessively in relation to the base.
- It is the primary objective of the present invention to provide a wheel mount of the skateboard or the like with a means to cushion the wheel mount.
- It is another objective of the present invention to provide a skateboard or the like with a wheel mount capable of confining the rotation of the axle.
- It is still another objective of the present invention to provide a skateboard or the like with a wheel mount capable of correcting the axle in action in due course so as to enhance the maneuverability of the skateboard or the like.
- The wheel mount of the present invention comprises a base, an axle, and a torsion spring. The base is fastened with the underside of a deck of the skateboard and is composed of a front plate and a rear plate parallel to the front plate. The front plate is provided at the bottom end with a stop piece extending therefrom. The axle is pivoted by a spindle between the front plate and the rear plate. The front end of the spindle is extended beyond the front plate. The axle is provided with an urging piece extending therefrom such that the urging piece is located under the stop piece. Two wheels are mounted on two ends of the axle. The torsion spring is fitted over the front segment of the spindle for cushioning the wheel mount and correcting the rotational direction of the axle.

- FIG. 2 shows a front view of the preferred embodiment of the present invention.
- FIG. 3 shows a bottom view of the preferred embodiment of the present invention.
- FIG. 4 shows an exploded view of the preferred embodiment of the present invention.
- FIG. 5 shows a schematic view of the preferred embodiment of the present invention in a first action state.
- FIG. 6 shows a schematic view of the preferred embodiment of the present invention in a second action state.
- FIG. 7 shows a schematic view of a first relative position of the torsion spring and the bushing of the preferred embodiment of the present invention.
- FIG. 8 shows a schematic view of a second relative position of the torsion spring and the bushing of the preferred embodiment of the present invention.
- FIG. 9 shows a schematic view of the present invention in conjunction with a scooter.
- As shown in FIGS.1-4, a
wheel mount 10 embodied in the present invention is intended for use in askateboard 12 or the like. Thewheel mount 10 comprises abase 20, anaxle 30, and atorsion spring 40. - The
base 20 is fastened with the underside of a deck of theskateboard 12 by four sets ofbolts 21 andnuts 22 and is composed of afront plate 24 and arear plate 25, which are parallel to each other and are separated from each other by a predetermined distance. Thefront plate 24 and therear plate 25 are of a rectangular construction. Thebase 20 is fastened with the deck in such a manner that thefront plate 24 and therear plate 25 form an angle with the deck of theskateboard 12. The angle so formed ranges between 25 and 65 degrees, preferably 60 degrees. Thefront plate 24 is provided with athrough hole 241, whereas therear plate 25 is provided with athrough hole 251. Thefront plate 24 is provided at the bottom end with arectangular stop piece 26 extending therefrom. - The
axle 30 is provided at the center with a cross throughhole 31 and is pivoted between thefront plate 24 and therear plate 25 by aspindle 38 which is put through the cross throughhole 31 of theaxle 30 and the throughholes front plate 24 and therear plate 25 in conjunction with twobushings 37 for reducing the friction between thespindle 38 and the cross throughhole 31. Theaxle 30 is provided with twoflat portions 32 opposite to each other and respectively in contact with thefront plate 24 and therear plate 25. Theaxle 30 is further provided at the center with anurging piece 33 extending from the side thereof such that theurging piece 33 is located under thestop piece 26. Theaxle 30 is further provided at both ends with an inner threadedportion 34. Twowheels 36 are respectively mounted on both ends of theaxle 30 in conjunction with twobolts 35 which are engaged with the two inner threadedportions 34 of both ends of theaxle 30. The front end of thespindle 38 is extended beyond thefront plate 24 and is provided with an outer threadedportion 381. - The
torsion spring 40 is fitted over the outer threadedportion 381 of thespindle 38. Anut 42 is engaged with the outer threadedportion 381 to secure thetorsion spring 40 at the front of thefront plate 24. Thetorsion spring 40 and thespindle 38 are provided with abushing 41 located therebetween. Thetorsion spring 40 has twoload segments 44, between which thestop piece 26 and theurging piece 33 are held. - As shown in FIGS. 5 and 6, when the
skateboard 12 negotiates the curve, theaxle 30 turns on thespindle 38 serving as an axis. In the meantime, one of theload segments 44 of thetorsion spring 40 is urged by theurging piece 33 to swivel while other one of theload segments 44 is urged by thestop piece 26 to remain at the original position. The recovery spring force of thetorsion spring 40 provides a cushioning effect as well as a correcting effect to guide theaxle 30. - When the
axle 30 is located at its initial position as shown in FIG. 2, there is a predetermined gap between thetorsion spring 40 and thebushing 41, as shown in FIG. 7. As theaxle 30 turns a predetermined angle, thebody 43 of thetorsion spring 40 is compressed to attach intimately to thebushing 41, as shown in FIG. 8. As a result, thetorsion spring 40 can no longer be deformed. Theaxle 40 can no longer turn in relation to thebase 20. In other words, the rotation of theaxle 40 is so confined that theskateboard 12 is relatively controllable. The present invention is applicable to ascooter 50, as shown in FIG. 9.
