A truck carrying member for coupling a conventional truck to a skateboard is described. The truck carrying member has comprises with a base plate rotatably coupled a pivoting plate at a pivot. The pivot comprises a bolt that provides an axis of rotation and a biasing member that keep that base plate and pivoting plate centered position. The base plate has a first mounting surface and a first pivoting surface that form a first obtuse angle. The pivot plate has a second mounting surface and a second pivoting surface that form a second obtuse angle that is less than the first obtuse angle. The second mounting surface extends downward from the skateboard when the truck carrying member is attached to a bottom surface of the skateboard. The pivot and biasing member help increase maneuverability of the skateboard by allowing the wheels of the truck to tuck in closer to the deck during turns.

A skateboard and a variable-rate elastomeric steering control spring include a boardside unitary body formed of an exterior first elastomer having a first durometer on the Shore A scale, and an interior second elastomer coupled to the first elastomer and extending at least a length of the exterior first elastomer, the second elastomer having a second durometer on the Shore A scale and a through hole disposed to receive a kingpin of the skate truck; a roadside unitary body formed of an exterior third elastomer having a third durometer on the Shore A scale, and an interior fourth elastomer coupled to the third elastomer and extending at least a length of the exterior third elastomer, the interior fourth elastomer having a fourth durometer on the Shore A scale and a through hole disposed to receive the kingpin; and wherein the first, second, third and fourth elastomers comprise at least two durometers on the Shore A scale between 65A and 100A to enable the boardside unitary body and the roadside unitary body to form the variable-rate elastomeric steering control spring when disposed on the king pin of the skate truck.

A skateboard system includes a first suspension member having first through third portions, each portion having a largest flat planar surface. The first portion includes a plurality of mount holes to mount it with a skateboard deck. The largest flat planar surface of the second portion is angled between fifteen and sixty degrees relative to the largest flat planar surface of the first portion and relative to the deck. The largest flat planar surface of the third portion is angled between fifteen and eighty degrees relative to the largest flat planar surface of the second portion. The third portion includes at least one opening to mount a truck assembly and/or a hanger with the third portion. The first suspension member flexes, such that an angle between the largest flat planar surface of the second portion and the deck decreases, in response to a first downward force on the deck.

A skateboard includes a board adapted for a user to stand with both feet thereon and having a major axis, and a front steering device and a rear steering device respectively disposed on front and rear sections of a bottom surface of the board along the major axis and each having two wheels. The front or rear steering device has a wheel seat disposed on the bottom surface of the board rotatably around a rotation axis which inclines downwards from front to rear, and a wheel rack disposed on the wheel seat rotatably or swingably around a main axis. An abutted surface is defined where the wheel seat and the wheel rack are abutted against each other. On an imaginary vertical plane including the major axis, where the rotation axis passes the abutted surface is in front of where the main axis passes the abutted surface.

A skateboard and a variable-rate elastomeric steering control spring include a boardside unitary body formed of an exterior first elastomer having a first durometer on the Shore A scale, and an interior second elastomer coupled to the first elastomer and extending at least length of the exterior first elastomer, the second elastomer having a second durometer on the Shore A scale and a through hole disposed to receive a kingpin of the skate truck; a roadside unitary body formed of an exterior third elastomer having a third durometer on the Shore A scale, and an interior fourth elastomer coupled to the third elastomer and extending at least a length of the exterior third elastomer, the interior fourth elastomer having a fourth durometer on the Shore A scale and a through hole disposed to receive the kingpin; and wherein the first, second, third and fourth elastomers comprise at least two durometers on the Shore A scale between 65 A and 100 A to enable the boardside unitary body and the roadside unitary body to form the variable-rate elastomeric steering control spring when disposed on the kingpin of the skate truck.

Apparatus, systems, and methods in which a truck carrying member, for coupling a conventional truck to a skateboard, comprises a pivoting plate and optionally a base plate. 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.

Embodiments of moving wheel platforms that minimizes wheel interactions with noncontinuous and uneven surfaces are described herein. Further, embodiments of moving wheel platforms with rotation-inhibiting structure are described herein. Implementing rotation-inhibiting structures onto or into the moving wheel platforms aids with eliminating wheel bite. Other embodiments can be described and claimed.

An inline skate includes a skate boot; a front wheel mount secured to a front portion of a bottom of the skate boot; a front wheel rotatably secured to the front wheel mount; a rear wheel mount secured to a rear portion of the bottom of the skate boot; a rear wheel rotatably secured to the rear wheel mount; and two adjustable shock absorbers disposed between the front wheel mount and the rear wheel mount.

A skateboard or longboard truck having configured to couple with a deck of the skateboard or longboard. The truck including a base and a hanger. The hanger disposed within a hanger aperture of the base. The hanger rotatably coupled with the base by a pivot assembly. The rotation of the hanger with respect to the base controlled by a compression assembly.

The present invention relates to sports equipment, namely, to roller skates design enabling an athlete to achieve high speed of movement with better comfort and improved motion control, in particular, in case of movement on a lower quality road surfaces. Roller skates consist of two skatesright and left ones, each comprising a spatial rectangular frame with its upper surface adapted to be attached to a frame of the corresponding shoe, either left or right one, and its lower side having two pairs of rollers pivotally attached thereto such that the rollers may rotate being in contact with the roadway and the rollers' axes are parallel to the frame plane, and according to the invention each pair of front and rear rollers of each skate is pivotally attached to the corresponding Z-shaped wheel arm, either front or rear one, which has its central section pivotally attached to the corresponding smaller side of the spatial rectangular frame, and the distance between the axes of the inner rollers of a skate is greater than the distance between the axes of the external rollers. The present invention is aimed to provide such roller skates, which would be more reliable and safe due to increased stability of the skates during movement, also in case of lower quality road surface and during cornering. This objective is achieved by way of creating conditions for uniform distribution of the load arising from the weight of the athlete during movement among all four rollers of each skate, even when moving on a lower quality road surface.
