Abstract
Description
- The present invention relates to a truck structure of a skateboard and, more particularly, to a structure on which a truck is detachably and attachably mounted.
- Heretofore, as one example of the truck structure of the skateboard, a truck structure has been known. It changes a rudder angle of a wheel W leftward and rightward corresponding to a deflection of the truck, as shown in Fig. 7.
- In such a
truck structure 30, a top face of a truck bearer portion 31 which journals the wheel W is formed in the disk-shape, and contacts a disc shaped-bottom face of a weightingtable base portion 32 fixed to a deck D, and is pivotally connected to P at a central position. - Further, the weighting
table base portion 32 is connected to abox portion 33 which stores a coil spring S, and an elastic force of the coil spring S can be adjusted by anadjustment bolt 35 which penetrates a hollow of the coil spring S. - Further, the top face of the truck bearer portion 31 is provided with a
protrusion portion 36, on the upper part of which is provided aprotrusion axis 37, and theprotrusion portion 36 is engaged with along hole 38 formed almost in the shape of a fan on the top face of the weightingtable base portion 32, and is allowed to slide within the range of thelong hole 38. - A base end of a
link piece 39 which penetrates theadjustment bolt 35 within thebox portion 33 and is pivotally connected thereto and pushingly abuts against a top end side of the coil spring S, is pivotally connected to theprotrusion axis 37. - The
protrusion axis 37 placed in a neutral position is arranged on the axis line of theadjustment bolt 35. When a force works to make turns leftward and rightward, both theprotrusion portion 36 and theprotrusion axis 37 turn leftward and rightward within a constant range, and gradually move away from the axis line of theadjustment bolt 35. Therefore, accompanied with this movement, thelink piece 39 is pulled and compresses the coil spring S to make it repulsive. - When no force is applied leftward and rightward on the truck, the wheel W is returned to the neutral position through the
link piece 39 by an elastic resettability of the coil spring S. - Hence, a conventional structure is integrally provided with a truck and a mechanism which allows the truck to turn leftward and rightward and, therefore, a modification or a replacement of a truck portion is not easily performed and there has been a problem in that a maintenance, a tuning, or the replacement and the like of the truck are hard to perform.
- Further, a pivotal stroke of the
link piece 39 is regulated by thelong hole 38 formed at the top face of the weightingtable base portion 32, and theprotrusion axis 37 is required to be provided on theprotrusion portion 36 and, thus, the structure has been made complicated. In addition, the crossing of the axis lines at both ends of thelink piece 39 imposes a torsional load to thelink piece 39, and this has necessitated a sufficient strength to be given to thelink piece 39. - Moreover, since the turning of the truck bearer 31 for the weighting
table base portion 32 concentrates a stress onto the pivot P, it tends to be fatigued and a problem may occur in its durability. - Hence, it is an object of the present invention to provide a truck structure of a skateboard capable of detachably and attachably mounting an independent truck on a support table of a support which has a built-in rudder mechanism.
- It is another object of the present invention to provide the truck structure of the skateboard, which is simple in a structure and high in reliability.
- In order to solve the above-described problem, in the truck structure of the skateboard provided with the support for turnably supporting the truck leftward and rightward from a neutral position and, at the same time, returnably urging the truck to the neutral position, the present invention is carried out in such a manner that the support comprises a weighting table fixed to a deck, and a support table which is pivotally connected to this weighting table and is made turnable leftward and rightward and detachably and attachably fixes the truck, wherein a link piece is pivotally connected between the weighting board and the support table and, when the support table turns leftward and rightward from the neutral position, the support table is returned to the neutral position by a repulsive force of an elastic member compressed by the link piece.
- In this way, according to the present invention, since the truck can be detachably and attachably mounted on the support, the user can select and use an optimum truck from among the complete trucks having a separate entity.
- Further, even at the time of a tuning-up, a repair and a replacement of the truck, these operations can be easily performed by dismounting the truck.
- Further, at the time of turns, the support is turned with a cap-shaped bearer portion put on there so as to cover the top face and a side peripheral face of the cylindrical bearer portion, so that there is no risk of a damage even when an external force is imposed to the direction other than pivoting and it is, therefore, possible to make stable turns.
- Furthermore, since the link piece is pivotally connected only to a protrusion axis protruded on the top face of the bearer portion and an adjustment bolt, the structure is simple and good in reliability.

-
- The best mode of a preferred embodiment of a truck structure of a skateboard of the present invention will be described below with reference to the drawings.
- A skateboard as shown in Fig.3 comprises a structure, which mounts a front wheel device W1 comprising a
truck 20 which journals a front wheel, and a rear wheel device W2 having thetruck 20 which journals a rear wheel to the deck D. - The truck structure of this embodiment in the case of the illustrated example, is used as the rear wheel device, in the present invention. It may be used either for the front wheel side or the front and the rear wheel side.
- This truck structure, as illustrated in Fig.2, comprises a structure provided with a
support 1 which turnably supports thetruck 20 which journals a wheel W as a wheel, leftward and rightward from a neutral position and, at the same time, urges thetruck 20 to a neutral direction. - The
support 1, as illustrated in Fig. 1, comprises a weighting table 2 fixed to a deck D and a support table 10 which is pivotally connected to the weighting table 2 and detachably and attachably fixes thetruck 20. - The weighting table 2, as more distinctly illustrated in Fig. 4, comprises a
base portion 4 cylindrically protruded on abase piece 3 which is fixed to the deck D by screws through holes 3a and the like. - In the case of the illustrated example, the
base portion 4 is erected by slightly inclining to the side on which thetruck 20 is mounted. - A
backside 3b of thebase piece 3 is notched in a fan shape with a top face (the deck D side) of thebase portion 4 exposed in a circular arc shape, and aprotrusion axis 6, which is pivotally connected to one end of alink piece 7 to be described later, is protruded (see Fig.5(A)). - Next, the support table 10 comprises a cap-
shaped bearer 11 which is set at the same concentric diameter as that of thebase portion 4, and amounting piece portion 12, which extends from the bottom face (the top face in Fig. 1) of thebearer portion 11 to one side, and a boxshaped storage portion 13 is integrally formed on the top face (the deck D side) of themounting piece portion 12. - The
bearer portion 11 has an C-shaped peripheral wall in its cross section, and thestorage portion 13 comprises an almost U-shaped peripheral wall in its cross section, and the peripheral walls of the former and the latter become integrated so that a hollow portion between thebearer portion 11 and thestorage portion 13 is communicated with each other, and the surface of thebearer portion 11 is formed almost in the shape of a keyhole. - The
bearer portion 11 is outwardly fitted so as to cover the top face and the side peripheral face of thebase portion 4, and pivotally connects thebase portion 4 and thebearer 11 by thepivot 5 along the axis line. Therefore, thebearer portion 11 is connected rotatably leftward and rightward with the base portion as a center. - The
mounting piece portion 12 is flat in the undersurface, and is arranged so as to be inclined to the deck D. - Mounting
holes 12a for fixing thetruck 20 are drilled on the four corners of themounting piece portion 12. A knowntruck 20 is used as thetruck 20 to be fixed to thismounting piece portion 12. - The
truck 20, as illustrated in Fig. 2 and Fig. 4, one example of which is shown in the present embodiment, comprises a structure in which amain body portion 22 having ahanger 23 journaling the wheel W and apivot 24 is fixed to apedestal portion 21 having a pivot hole by apin 26 or a bolt throughbush rubbers 25. -
Mounting holes 21a drilled in thepedestal portion 21 are aligned to themounting holes 12a of themounting piece portion 12, and bolts are passed through there and tightly fastened by nuts and the like, thereby detachably and attachably fixing thetruck 20 to the support table 10. - Here, while the
truck 20 is directly fixed to the support table 10, a known spacer (not shown) may be interposed between themounting piece portion 12 and the support table 10 so as to mount thetruck 20. - In the present embodiment, although the
trucks 20 used in the front wheel device and the rear wheel device of the skateboard are regarded as having the same structure, both of the devices may be of different forms and structures. - Next, a coil spring S is fitted into the
storage portion 13. - Further, the
adjustment bolt 14 with a top end thereof cut with threads is screwed at the center of therear wall 13a opposed to the open side in the peripheral wall of thestorage portion 13, and extends longitudinally through the center of thestorage portion 13. Ahead portion 14a, in which a knurl is formed, is hung at therear wall 13a. - Here, a
rear end center 12b of themounting piece portion 12, which corresponds to a position of thehead portion 14a of theadjustment bolt 14, is notched so that it does not hit against thehead portion 14a. - This
adjustment bolt 14 extends by penetrating a hollow of the center of the coil spring S within thestorage portion 13, and adisc nut 15 formed in a pentagonal shape is screwed on the top end of theadjustment bolt 14, so that it does not rotate within thestorage portion 13. - Hence, by rotating the
head portion 14a of theadjustment bolt 14, thedisc nut 15 can be screwed back and forth along the axial direction of theadjustment bolt 14. - This
disc nut 15 pushingly abuts against the top end of the coil spring S, and repulsively compresses the coil spring S together with thelink piece 7 to be described later. - Next, the
link piece 7 is placed between the weighting table 2 and the support table 10. - This
link piece 7 is formed of an almost L-shaped plate piece in its cross-section, and the top end of alongitudinal piece 7a thereof is screwed to aprotrusion axis 6 which is fixed on the top face of thebase portion 4, and ahole 8 is drilled on a bentshort piece 7b and covers the coil spring S within thestorage portion 13, and theadjustment bolt 14 is inserted at a position adjacent to the rear end of this coil spring S, and the rear end of thelink piece 7 is pivotally connected to thebolt 14. - Hence, a rotation to the fastening direction of the
head portion 14a of theadjustment bolt 14 gradually compresses the coil spring S held between thedisc nut 15 and the bentshort piece 7b of thelink piece 7 due to an advancement of thedisc nut 15 toward thelink piece 7, and a reverse rotation gradually weakens the compression due to a retreat of thedisc nut 15, thereby making it possible to perform a fine adjustment of an elastic force. - Next, an action of the truck structure of the skateboard will be described.
- A gravitational movement or a motion of a player on the deck D from the neutral position shown in Fig. 5 causes a biased force and, according to this force, together with the support table 10 of the
support 1, thetruck 20 makes a turn to one side with thepivot 5 as a supporting point. - The leftward and rightward pivotal movement of the support table 10 allows the
link piece 7 to be moved and displaced at the same time (See Fig.6). - Here, the
protrusion axis 6 at the neutral position shown in Fig.5 is arranged on the axis line of theadjustment bolt 14 so as to maintain the shortest distance. At the turn position illustrated in Fig. 6, theprotrusion axis 6 gradually moves away from the axis line of theadjustment bolt 14 in proportion to the pivotal movement of the support table 10, so that thelink piece 7, both ends of which are pivotally connected to theprotrusion axis 6 and theadjustment bolt 14, is pulled to the direction in which the coil spring S is compressed. - In this way, turns made leftward and rightward from the neutral position allow the repulsive force of the coil spring S to become stronger as a rudder angle is made larger, thereby reducing an external force which acts upon the turn direction. On the other hand, an elimination of the external force applied on the turn direction allows the
truck 20 to return to the neutral position by the elastic repulsive force stored in the coil spring S. - Here, since the
support 1 of the present embodiment, as shown in Fig.1 and Fig.2, sets the mountingpiece portion 12 of the support table 10 at the inclined surface, a mounting angle to the deck D of thetruck 20 changes. However, the mountingpiece portion 12 may be provided so as to be horizontal to the deck.
