Skateboard truck with inverted king pin and integrated kingpin fastener
A skateboard truck includes a metal bolt called a kingpin and a threaded fastener, called a hex nut, which when combined hold the two main components of a truck together: the baseplate, which is mounted to the bottom surface of the skateboard deck; and the turning part of the truck called the hanger, which is mounted onto the baseplate by means of the kingpin, and affixed tightly into the baseplate by means of a threaded hex nut. Two bushings placed along the shaft of the kingpin and on either side of a flange protruding from the hanger hold the hanger in place by the tightening of the kingpin into the threaded shaft nut fastener. The kingpin is oriented such that a threaded portion of the kingpin (on an end opposite a bolt head portion) is generally facing towards a bottom surface of the skateboard deck.
1. A skateboard truck, comprising:
a two-sided baseplate configured for mounting to a bottom surface of a skateboard deck;
a hanger configured to hold an axle;
wherein a first side of the two-sided baseplate is positioned against the bottom surface of the skateboard deck and comprises a cavity for housing a fastening nut, wherein the fastening nut comprises a monocoque hex nut, a first portion of the fastening nut comprises a hex portion, and a second portion of the fastening nut comprises a shaft portion;
wherein a second side of the two-sided baseplate is adjacent to the first side of the two-sided baseplate;
a through hole connecting the cavity and the second side of the two-sided baseplate; and
a kingpin bolt having a threaded portion affixed to the fastening nut to secure the two-sided baseplate and hanger together relative to the bottom surface of the skateboard deck via the through hole.
2. The skateboard truck of claim 1 , wherein the kingpin bolt is configured to be tightened into the two-sided baseplate.
3. The skateboard truck of claim 1 , wherein a first end of the kingpin bolt comprises the threaded portion, and wherein a second end of the kingpin bolt comprises a bolt head configured in one of a hex shape or a round shape.
4. The skateboard truck of claim 3 , wherein the kingpin bolt is oriented such that the first end of the kingpin bolt generally faces the bottom surface of the skateboard deck.
5. The skateboard truck of claim 1 , wherein the hex portion and the shaft portion are formed to define a center hole throughout.
6. The skateboard truck of claim 5 , wherein:
an inside surface of the center hole formed throughout the hex portion and the shaft portion comprises cut threads; and
an outer surface of the monocoque hex nut has a smooth circular diameter with no threads.
7. The skateboard truck of claim 1 , wherein the two-sided baseplate comprises aluminum.
8. The skateboard truck of claim 1 , wherein the two-sided baseplate is formed in a shape of one of a rectangle, oval, or square.
9. The skateboard truck of claim 1 , wherein the first side of the two-sided baseplate is configured to be positioned coincident with the bottom surface of the skateboard deck.
10. The skateboard truck of claim 9 , wherein the first side of the two-sided baseplate comprises the cavity to fit the first portion of the fastening nut.
11. The skateboard truck of claim 10 , wherein the two-sided baseplate comprises the through hole that is bored through the cavity and out to the second side of the two-sided baseplate.
12. The skateboard truck of claim 11 , wherein the two-sided baseplate through hole has a same inside dimension as an outer major surface of the fastening nut.
13. The skateboard truck of claim 1 , wherein the hanger comprises an aluminum hanger configured to hold a steel axle.
14. The skateboard truck of claim 13 , wherein the hanger comprises a mounting flange with a through hole at a center of the mounting flange.
15. The skateboard truck of claim 13 , wherein a major axis of the axle is coincident to a major axis of the hanger.
16. The skateboard truck of claim 13 , wherein the axle comprises two axle ends with threads cut into each axle end.
17. The skateboard truck of claim 16 , wherein each axle end is configured to extend beyond an outer surface of the hanger.
18. The skateboard truck of claim 16 , wherein bearings and wheels are affixed to each axle end.
19. The skateboard truck of claim 13 , wherein an axis of the axle is coaxial with an axis of the hanger.
