Knock-down quarter pipe for skateboarders, bikers and in-line skaters

A knock-down quarter pipe comprising

• a horizontal base;
• pairs of front and rear legs extending up from the base and for placement on a support surface below the base;
• a deck supported by the legs at a selected elevation above the base, said deck having an upper surface and a front edge defining a shelf thereat which is elevated above said pair of front legs;
• a rigid coping rail seated on said shelf so that the rail is substantially level with said upper surface of the deck, said rail having a pair of stubs extending down below said deck and being fastened to said pair of front legs;
• a ramp having first and second ends and an upper surface extending between said ends, and
• connections connecting the first end of the ramp adjacent and parallel to the front edge of the deck so that the second end of the ramp is spaced in front of the base and rests on the support surface.

A knock-down quarter pipe for bikers, skateboarders and in-line skaters comprising

• a deck having a rear edge, a front edge defining a lateral trough therein and a surface extending between said edges;
• a rigid grind rail seated in said trough so as to be substantially level with said surface;
• a pair of front legs and a pair of rear legs extending down from the deck to a common plane, said pair of front legs having upper ends located directly under said grind rail;
• connections connecting said grind rail to said pair of front legs, and
• a ramp having upper and lower ends and connected adjacent to the front edge of the deck so that the upper end of the ramp is in front of and substantially parallel to said grind, rail and the lower end of the ramp is spaced in front of said pair of front legs in said plane.

A knock-down quarter pipe comprising

• a platform assembly including
• a deck having an upper surface and a front edge defining a lateral trough therein,
• a rigid grind rail seated in said trough so that the rail is substantially level with said upper surface,
• means for anchoring the rail in the trough, and
• a pair of front legs and a pair of rear legs extending down from said deck to a common plane, and
• a ramp assembly connected to said platform assembly, said ramp assembly including
• an entry section having a front end defining a sharp edge lying in said common plane and a rear end defining a shelf,
• a first ramp section which extends from said deck down to said shelf, said first ramp section having a lower end overlying said shelf,
• a second ramp section which extends from said deck down to said shelf next to the first ramp section, said second ramp section having a lower end overlying said shelf, and
• securements for securing the lower ends of the first and second ramp sections to said shelf.
