Skateboard base plate and associated systems
Exemplary embodiments are directed to a base plate for a skateboard that includes a body, and first and second pivot cups. The body includes a proximal end and a distal end. The first pivot cup extends from the body at or near the distal end. The second pivot cup is spaced from the first pivot cup and extends from the body at or near the proximal end. The second pivot cup defines an outer perimeter surface having an uninterrupted height. The second pivot cup includes an opening extending therethrough and surrounded by the outer perimeter surface of the second pivot cup. The second pivot cup includes one or more channels extending from the opening and through at least a portion of the second pivot cup. The one or more channels extend through at least the portion of the second pivot cup without extending through the outer perimeter surface.
1. A base plate for a skateboard, comprising:
a body including a proximal end and a distal end;
a first pivot cup extending from the body at or near the distal end; and
a second pivot cup spaced from the first pivot cup and extending from the body at or near the proximal end, the second pivot cup (i) defining an outer perimeter surface having an uninterrupted height, a thickness of the uninterrupted height of the second pivot cup dimensioned greater than a thickness of the first pivot cup, (ii) includes an opening extending therethrough and surrounded by the outer perimeter surface of the second pivot cup, the opening of the second pivot cup configured to at least partially receive therein a wave cam such that the wave cam is surrounded by the outer perimeter surface of the second pivot cup, and (iii) includes one or more channels extending from the opening and through at least a portion of the second pivot cup, the one or more channels extending through at least the portion of the second pivot cup without extending through the outer perimeter surface.
2. The base plate of claim 1 , wherein the outer perimeter surface of the second pivot cup defines a substantially uniform height.
3. The base plate of claim 1 , wherein the one or more channels are configured to receive an extension of a locking key.
4. The base plate of claim 1 , wherein the second pivot cup includes two channels on opposing sides of the opening and extending through at least a portion of the second pivot cup.
5. The base plate of claim 1 , wherein the first pivot cup includes an opening extending therethrough and configured to receive a kingpin.
6. The base plate of claim 1 , wherein the body includes a base configured to be mounted to a deck of the skateboard, and the first and second pivot cups are angled relative to the base of the body.
7. The base plate of claim 1 , wherein the second pivot cup includes an inner surface facing the first pivot cup and an outer surface facing away from the first pivot cup, the outer surface of the second pivot cup curved inwardly in a concave manner.
8. A base plate for a skateboard, comprising:
a body including a proximal end and a distal end;
a first pivot cup extending from the body at or near the distal end; and
a second pivot cup spaced from the first pivot cup and extending from the body at or near the proximal end, the second pivot cup (i) defining an outer perimeter surface, includes an opening extending therethrough and surrounded by the outer perimeter surface of the second pivot cup, the opening of the second pivot cup configured to at least partially receive therein a wave cam such that the wave cam is surrounded by the outer perimeter surface of the second pivot cup, and (iii) includes a channel extending from the opening and through at least a portion of the second pivot cup without extending through the outer perimeter surface.
9. The base plate of claim 8 , wherein the outer perimeter surface of the second pivot cup defines a substantially uniform height, the uniform height of the second pivot cup dimensioned greater than a height of the first pivot cup.
10. The base plate of claim 8 , wherein the one or more channels are configured to receive an extension of a locking key.
11. The base plate of claim 8 , wherein the second pivot cup includes two channels on opposing sides of the opening and extending through at least a portion of the second pivot cup.
12. The base plate of claim 8 , wherein the first pivot cup includes an opening extending therethrough and configured to receive a kingpin.
13. The base plate of claim 8 , wherein the body includes a base configured to be mounted to a deck of the skateboard.
14. A truck for a skateboard, comprising:
a base plate comprising:
a body including a proximal end and a distal end;
a first pivot cup extending from the body at or near the distal end; and
a second pivot cup spaced from the first pivot cup and extending from the body at or near the proximal end, the second pivot cup (i) defining an outer perimeter surface having an uninterrupted height, a thickness of the uninterrupted height of the second pivot cup dimensioned greater than a thickness of the first pivot cup, (ii) includes an opening extending therethrough and surrounded by the outer perimeter surface of the second pivot cup, the opening of the second pivot cup configured to at least partially receive therein a wave cam such that the wave cam is surrounded by the outer perimeter surface of the second pivot cup, and (iii) includes one or more channels extending from the opening and through at least a portion of the second pivot cup, the one or more channels extending through at least the portion of the second pivot cup without extending through the outer perimeter surface; and
a hanger movably mounted between the first and second pivot cups of the base plate.
15. The truck of claim 14 , wherein the outer perimeter surface of the second pivot cup defines a substantially uniform height.
16. The truck of claim 14 , comprising a spring disposed between the hanger and the first pivot cup.
17. The truck of claim 16 , wherein the spring is a compression spring with a safe travel configured to eliminate compressive set.
18. The truck of claim 14 , comprising a locking key engaged with the wave cam.
19. The truck of claim 18 , comprising a kingpin extending through the first pivot cup, the second pivot cup, the locking key, and the wave cam, the kingpin including a threaded section configured to engage with a nut to maintain assembly of and tune the base plate, the hanger, a spring and the wave cam, the threaded section of the kingpin limited in length to prevent overtightening of the assembly.
20. The truck of claim 14 , wherein the second pivot cup includes an inner surface facing the first pivot cup and an outer surface facing away from the first pivot cup, the outer surface of the second pivot cup curved inwardly in a concave manner.
