Abstract:
1. A skateboard bushing securement apparatus, employable in combination with a skateboard truck assembly having a hanger in a sandwiched engagement between a first side of a top bushing and first side of a bottom bushing where a second side of said top bushing abuts a base plate, and where a kingpin engaged at a first end through said base plate axially communicates through said top bushing, said hanger, and exits at a second side of said bottom bushing, for engagement at a distal end to a configuration in an as-used position, to a nut, said bushing securement apparatus comprising: a first base washer having a first side opposite a second side and having a central aperture communicating therebetween; an annular ring portion projecting away from a perimeter edge of said second side, said annular ring portion having an inside edge defining an interior perimeter of a cavity defined by an area between said annular ring portion and said second side; a first sleeve washer having a first surface and a second surface and having a central passage communicating therebetween; a sidewall communicating between said first surface and second surface of said first sleeve washer and defining a perimeter thereof; said perimeter of said first sleeve washer sized smaller than an interior perimeter of said cavity of said first base washer; said first surface of said first sleeve washer positionable during an as-used configuration of said securement apparatus, in a communication against an area of said second surface of said first base washer within said cavity; an annular sleeve portion projecting in a direction away from both said first surface and second surface of said first sleeve washer; said annular sleeve portion having an interior wall surface having a perimeter substantially equal to a perimeter of said central passage; said annular sleeve portion having an exterior wall surface opposite said interior wall surface, said exterior wall surface having an exterior circumference; and said interior perimeter of said cavity of said first base washer sized equal to or slightly less than a circumference of said top bushing, whereby with said securement apparatus in said as-used position, with said kingpin communicating through said base plate, said central aperture of said first base washer, said central passage of said sleeve washer and an axial inside cavity of said top bushing, said inside edge of said annular ring portion contacts a portion of said circumference of said top bushing at a first end thereof, and said annular sleeve portion projects into said axial cavity with said exterior wall surface adjacent a wall defining said axial cavity of said top bushing.
