Definitions

  • This invention relates to truck assemblies for skateboards or other similar vehicles and in particular to a truck assemblies which enable steering characteristics of a skateboard or other similar vehicle to be varied.
  • the skateboard in many different designs have developed since introduction of the basic skateboard configuration.
  • the skateboard comprises a deck having on its lower side front and rear truck assemblies, each of which supports opposite pairs of wheels on a transversely extending axle.
  • the axles are mounted for pivotal movement about axes which extend at an obtuse angle to the plane of the skateboard deck and usually, the pivot axes of the axles of the front and rear truck assemblies are of an opposite inclination.
  • Skateboards are therefore able to be steered by the rider leaning or shifting his or her weight to one side or other of the board thereby pivoting the deck of the skateboard in opposite directions relative to the longitudinal axis of the skateboard, this causing fore and aft pivotal movement of the wheel axles in opposite directions.
  • the skateboard truck assemblies incorporate resilient pads which resist pivoting the axle of the wheels and tends to return the wheels to a neutral position.
  • Skateboards of this type also incorporate truck assemblies however some difficulties are associated with steering of this type of board and maintaining their stability during a number of particular riding techniques if conventional truck assemblies are used. It is also desirable to enable adjustment of the steering characteristics of this type of skateboard to suit different applications. For this purpose it has been known to place an angled or wedge-shaped shaped packer between the skateboard truck assembly and the underside of the skateboard deck to adjust the pivot axis of the truck assembly axle and to raise the height of the skateboard deck above the axle line. This procedure however is obviously time-consuming as it involves removal of the track assembly and then reassembling with the use of the angled packer between the truck assembly and board.
  • a further disadvantage is that each time a different angle is required for the plane of operation of the axles of the skateboard wheels, a packer of a different angle is required. Riders also fit different trucks from different manufacturers that have different pivot angles to either front or rear locations to achieve the steering stability or maneuvering characteristics they need for a particular style of riding.
  • the present invention aims to provide an improved truck assembly particularly suited for us with longboard type skateboards but which is also suited to use with other forms of skateboard or other rideable vehicle.
  • the present invention aims to provide a truck assembly in which the steering characteristics of the truck assembly can be selectively varied in a simple and effective manner.
  • the present invention in a further aspect aims to provide a skateboard incorporating truck assemblies according to the present invention.
  • the present invention aims to provide an improved method and means for mounting a truck assembly to a deck of a skateboard or other rideable vehicle.
  • the present invention thus provides, in a first preferred aspect, a truck assembly for use with skateboards, said truck assembly having a main body adapted to be mounted to the underside of the deck of said skateboard, an axle for supporting a pair of skateboard wheels, means for mounting said axle to said main body in such a manner as to allow pivotal movement of said axle in a plane and in opposite directions relative to said body to effect steering of said skateboard and means for selectively adjusting said plane of movement of said axle whereby to enable the steering characteristics of said skateboard to be varied.
  • skateboard as used herein includes conventional skateboards, longboard skateboards or any other rideable vehicle which uses truck assemblies.
  • pivot means mount the axle to the main body and define an axis of pivotal movement of the wheel axle and therefore the plane of pivotal movement of the wheel axle.
  • the pivot means is suitably provided intermediate opposite ends of the wheel axle and adjustment means are suitably provided for selectively adjusting the pivot means to adjust the plane of movement of the wheel axles.
  • the axis of the pivot means lies in a plane extending longitudinally of and normal to the plane of the skateboard deck and the adjustment means adjusts the position of the axis of the pivot means in that plane. This adjustment may also adjust the plane of movement of the wheel axle which may be normal to the axis of pivotal movements.
  • the pivot means in one preferred form may comprise a pair of opposite trunnions and means is provided for supporting the trunnions to the main body for rotation about the pivot axis of the pivot means to allow the axle of the wheels of the truck assembly to move in their plane of movement.
  • the trunnions support means are adjustable to enable variation of the pivot axis of the trunnions.
  • Means may be provided for the unrestricted adjustment of the position of the trunnion support means and therefore unrestricted adjustment of the plane of pivotal movement of the axle of the truck assembly.
  • means may be provided for adjustment of the position of the trunnions support means and therefore plane of pivotal movement of the axle of the truck assembly to one of a number of discrete positions.
  • the trunnions support means comprises an adjustable support boss mounted to the truck body for rotational movement about an axis extending substantially normal to the longitudinal axis of the skateboard and parallel to the deck of the skateboard.
  • the axle which supports the skateboard wheels may beconcentric to the axis of rotational movement of the boss when the axis is in a “neutral” position.
  • the trunnions support boss may be journalled to the truck body or supported by any suitable bearing or bush arrangement to the truck body.
  • the trunnions may typically be supported for rotation in bearings or bushes in the support boss.
  • the support boss may be provided with an adjustment arm and means may be provided for adjusting the position of the adjustment arm to thereby adjust the rotational position of the support boss and the pivot axis of the trunnions.
  • a series of locating means may be provided to locate and define different positions of the adjustment arm.
  • the locating means may for example be in the form of a plurality of stops, apertures, markers or indicators.
  • the adjustment arm may include means which cooperate with, or which may be aligned with, a selected stop, aperture, marker or indicator to set or locate the position of the adjustment arm and boss.
  • the adjustment arm may include a pin which can locate in a selected aperture.
  • the pin may be spring loaded to cooperate with a selected aperture to securely locate and hold the arm in a selected position.
  • the pin may have an enlarged head which facilitates its detachment from a selected aperture.
  • the arm extends generally radially relative to the axis of rotational movement of the boss and the locating means are arranged along an arc or curve on the main body of the truck assembly.

  • the truck assembly 10 includes a main truck body 11 which is adapted to be mounted to the underside of the deck of a skateboard via a mounting block 12 which may be secured by bolts, screws or fasteners to the skateboard deck and with or without an intermediate spacer 13 .
  • Complementary coupling means are provided on the truck body 11 , mounting block 12 and spacer 13 which allow them to be slidably interengaged.

  • the complementary coupling means comprise a rib and groove type coupling comprising a pair of opposite parallel ribs or edges 14 and 14 ′ on the lower side of the truck body 11 and spacer 13 and a pair of opposed parallel grooves 15 and 15 ′ on the upper side of the spacer 13 and mounting block 12 .
  • the ribs 14 and 14 ′ and grooves 15 and 15 ′ are at substantially the same lateral spacing such that the truck body 11 may be slid longitudinally onto the mounting block 12 or spacer 13 through the cooperation between the opposed ribs 14 or 14 ′ and grooves 15 or 15 ′ and similarly the spacer 13 may be slid longitudinally onto the mounting block 12 through the cooperation between the opposed ribs 14 ′ and grooves 15 ′.
  • the truck body 11 is maintained in engagement with the mounting block 12 or spacer 13 by latching devices comprising a latching member 16 and 16 ′ on a spring or resilient finger 17 and 17 ′ fixed to the mounting block 12 or spacer 13 .
  • the latch members 16 and 16 ′ are adapted to locate in a recess 18 on the underside of the truck body 11 and the latch member is adapted to located in a recess 18 ′ on the underside of the spacer 13 to retain the body 11 to the block 12 or spacer 13 , or spacer 13 to the mounting block 12 .
  • the body 11 may be detached from the block 12 or spacer 13 or the spacer 13 may be detached from the mounting block 12 by pushing the free end of the finger 17 or 17 ′ downwardly to release the latch member 16 or 16 ′ from the recess 18 or 18 ′ to allow the truck body 11 to be slidably disengaged from the mounting block 12 or spacer 13 , or spacer 13 from the mounting block 12 .

  • the truck body 11 includes a transversely extending bore 19 which is sized to accept a steering adjustment boss 20 (see also FIGS. 3 and 4) which is supported rotatably in the bore 19 by being inserted from one side thereof and which is retained by means of a circlip 21 on the opposite side such that the boss 20 is capable of rotation about the axis 22 of the bore 19 , that axis 22 extending substantially normal to the longitudinal axis of the skateboard deck to which the truck assembly 10 is mounted.
  • the boss 20 may be journalled in the bore 19 or mounted via bearings therein.
  • the boss 20 is also provided with a central bore 23 which is coaxial with the bore 19 of the body 11 .
  • the bore 23 is of a somewhat rectangular configuration and receives the main truck axle 24 which supports at opposite ends via bearings the wheels 25 of the truck assembly 10 .
  • the rectangular shape of the bore 23 accommodates pivotal movement of the truck axle 24 as described further below.
  • the truck axle 24 is mounted to the boss 20 by means of a trunnions arrangement comprising a pair of opposite trunnions 26 (see FIGS. 3 and 4) which are arranged intermediate the opposite ends of the axle 24 and which extend normal to the longitudinal axis of the axle 24 .
  • the trunnions 26 may be defined by a pin inserted into a bore which extends transversely through the axle 24 and projects on opposite sides thereof.
  • the trunnions 26 may be defined by a pair of pins which are provided on opposite sides of the axle 24 and interconnected for example by a threaded connection through the axle 24 .
  • Other arrangements however may be provided for defining the trunnions 26 .
  • the trunnions 26 are supported in opposite bores 27 in the boss 20 via bearings 28 such as roller or ball bearings or bushes so as to allow for smooth pivoting movement of the axle 24 about the axis 29 of the trunnions 24 .
  • the bores 27 may be closed on their outer sides by end caps. It will be apparent that in the position of FIG. 1, the longitudinal axis of the axle 24 is coaxial with the axis 22 of the bore 19 .
  • the orientation of the pivot axis 29 of the trunnions 26 can be adjusted however by rotation of the boss 20 in the bore 19 of the truck body 11 .
  • an arm 30 which is integrally formed with the boss 20 extends radially from the boss 20 .
  • the free end of the arm 30 is provided with a spring loaded stop pin 31 which is normally urged by an internal spring 32 in the arm 30 to the position of FIG. 3 extending parallel to the axis 22 of the bore 19 .
  • the pin 31 is provided with a head 33 to enable retraction of the pin 31 against the force of the spring 32 .
  • the pin 31 may locate in one of a series of holes 34 provided at spaced apart positions along a curved member 35 of the body 11 which is centered on the rotational axis 22 of the boss 20 .
  • the pin 31 is retracted by grasping the pin head 33 and the arm 30 is then rotated in a desired direction to rotate the boss 20 arid reposition the stop pin 31 in alignment with another one of the holes 34 after which the pin 31 may be released to locate within that hole 34 to hold the arm 30 and boss 20 in a set position. It will be apparent that during this movement, axle 24 remains concentric with the axis 22 of the bore 19 .
  • the boss 20 is also provided with relief grooves 36 and 37 extending from and on opposite sides of the bore 23 and in alignment with the arm 30 , the grooves 36 and 37 and the rectangular configuration of the bore 23 accommodating pivotal movement of the axle 24 in a plane 38 (see FIG. 4) perpendicular to the pivot axis 29 of the trunnions 26 . It will be appreciated that rotation of the steering boss 20 as described above will rotate the pivot axis 29 of the axle 24 as defined by the trunnions 26 to thereby vary the orientation of the plane 38 along which the axle 24 may pivot.
  • pairs of tension springs 39 are provided on opposite sides of the truck body 11 to extend between anchoring points 40 on the truck body 11 on either side of the axle 24 , and a lug 41 mounted to the axle 24 at a position spaced outwardly from the body 11 .
  • the springs 39 provide a biasing force to resist pivotal movement of the axle 24 about the trunnions axis 29 .
  • the springs are mounted at an angle to the axle in a triangular pattern so that their opposing resistance to the body weight needed to tilt the deck to produce turning remains reasonably constant for the range of deck angles.
  • the axle 24 preferably comprises a central part 42 which carries or is connected to the trunnions 26 and detachable opposite end parts 43 which carry the wheels 25 .
  • the end parts 43 may be threaded for threaded engagement with opposite ends of the central part 42 with the spring mounting lugs 41 arranged therebetween. This arrangement also allows different length end parts 43 to be substituted or removed completely for different applications or for supporting wheels 25 of different sizes or configurations.
  • pairs of truck assemblies 10 are mounted at spaced apart fore and aft positions via respective mounting blocks 12 and spacers 13 (if required) to the underside of the deck 44 to form a skateboard 45 typically a longboard type skateboard.
  • the positions of the steering bosses 20 of each truck assembly 10 may then be varied depending upon the steering characteristics required in the skateboard 45 . In the position shown in FIG.
  • the steering effect of both the front and rear truck assemblies 10 may be selectively varied by simply readjusting the position of the arm 30 by retracting the stop pin 31 and repositioning the pin 31 in one of the holes 34 with movement of the pin 31 outwardly from the center position resulting in a reduced turning circle or a sharper steering effect with the same pivotal movement of the skateboard deck 44 .
  • the rider is therefore able in a simple and effective manner to selectively adjust the steering required for different circumstances or different applications.
  • the steering adjustment arms 30 of the truck assemblies 10 are angled in opposite directions such that when the deck 44 is pivoted about the longitudinal axis 46 , the front and rear axles 24 will pivot in opposite directions.
  • the arm 30 of the rear truck assembly 10 in this instance is located in the central position as illustrated in FIG. 1 where the deck of the skateboard 45 is planar.
  • the arm 30 is adjusted such that it and the possible plane 38 of pivotal movement of the axle 24 are at right angles to the axis 46
  • the truck assemblies 10 of the invention may be applied to skateboard decks of many different configurations and various steering characteristics of the skateboard can be achieved by simply adjusting the adjustment arms 30 in the manner described. Further handling characteristics can be varied by changing the spacers 13 or alternatively eliminating the spacers 13 . Further it will be appreciated that other arrangements may be provided for supporting the axle 24 of the truck assembly 10 such that the angle of its possible plane of pivotal movement can be adjusted to adjust the steering characteristics of the truck assembly 10 .
