For example, the base and pivoting plates are rotatably coupled at a pivot comprising an elastic flexible member that biases the pivoting plate to a default position (e.g., center of the base plate). Preferably, the base plate and pivoting plate each has a mounting surface and a pivoting surface that form an obtuse angle, such that the mounting surface of the pivoting surface extends downward. Another example of a pivoting plate comprises flexible members that allow the pivoting plate to tilt relative to the skateboard. ## Claims ### Claim 1 A truck carrying member that couples a truck to a skateboard, the truck comprising a wheel axle, comprising: a base plate having a first mounting surface for coupling with the skateboard and a first pivoting surface, wherein the first mounting surface and the first pivoting surface form a first obtuse angle; a pivoting plate having a second mounting surface for coupling with the truck and a second pivoting surface, wherein the second mounting surface and second pivoting surface form a second obtuse angle; wherein the first pivoting surface and the second pivoting surface are rotatably coupled at a pivot comprising a flexible member that biases the pivoting plate from an off-center position to a center position relative to a longitudinal axis of the base plate; and wherein the second obtuse angle is less than the first obtuse angle such that the second mounting surface extends downward from the skateboard when the truck carrying member is attached to a bottom surface of the skateboard. ### Claim 2 (depends on 1) The truck carrying member of claim 1, wherein the pivoting plate has a first recess sized and dimensioned to receive a first end of the flexible member. ### Claim 3 (depends on 2) The truck carrying member of claim 2, wherein the base plate has a second recess sized and dimensioned to receive a second end of the flexible member. ### Claim 4 (depends on 3) The truck carrying member of claim 3, wherein the flexible member mechanically locks with the pivoting and base plates to prevent rotation with respect to the first end and second end of the flexible member, respectively. ### Claim 5 (depends on 4) The truck carrying member in claim 4, wherein the flexible member has a non-cylindrical cross-section. ### Claim 6 (depends on 1) The carrying member of claim 1, wherein the pivot further comprises a bolt about which the base plate and pivoting plate pivot. ### Claim 7 (depends on 1) The carrying member of claim 1, the flexible member is sufficiently flexible to allow the pivoting plate to rotate at least 15 degrees relative to the base plate. ### Claim 8 (depends on 1) The carrying member of claim 1, wherein, in the default position, the pivoting plate is at a center position relative to the base plate. ### Claim 9 (depends on 1) The carrying member of claim 1, wherein the flexible member comprises a bushing. ### Claim 10 (depends on 1) The carrying member of claim 1, wherein the flexible member comprises a polymer. ### Claim 11 (depends on 1) The truck carrying member of claim 1, wherein the second mounting surface extends downward between 5 degree to 45 degrees, inclusive, from the bottom surface of the skateboard, when the truck carrying member is attached to a bottom surface of the skateboard. ### Claim 12 (depends on 1) The truck carrying member of claim 1, wherein the truck carrying member increases the truck's turn angle by 5 to 45 degrees, inclusive, and decreases the truck's lean angle by 5 to 45 degrees, inclusive, compared to when the truck is used without the truck carrying adapter. ### Claim 13 (depends on 1) The carrying member of claim 1, wherein: the second pivoting surface of the pivoting plate further comprises a notch; and the first pivoting surface of the base plate further comprises a protrusion that is sized and dimensioned to move within the notch. ### Claim 14 (depends on 13) The carrying member of claim 13, wherein the pivoting member has a range of motion of less than 45 degrees clockwise and counterclockwise. ### Claim 15 (depends on 13) The carrying member of claim 13, wherein the pivoting plate is capable of pivoting such that the skateboard can angle to face a point around which a user is turning. ### Claim 16 (depends on 13) The carrying member of claim 13, wherein the pivot provides a smooth transition when pivoting. ### Claim 17 A truck carrying member that couples a truck to a skateboard, comprising: a pivoting plate having a mounting surface for attaching a truck; first and second fasteners for attaching the pivoting plate to a skateboard or a base plate; and wherein the first and second fasteners comprise first and second flexible members that allow the pivoting plate to tilt. ### Claim 18 (depends on 17) The truck carrying member of claim 17, wherein the first and second flexible members comprise a first bushing and a second bushing, respectively. ### Claim 19 (depends on 17) The truck carrying member of claim 17, wherein the first and second flexible members have sufficient flexibility to allow the pivoting plate to tilt at least 10 degrees, inclusive.
