ABSTRACT:
BACKGROUND OF THE INVENTION
The invention relates to skateboards and more specifically to a novel skateboard deck that has been designed to eliminate mechanical fastener structure from its top surface when the truck assemblies have been attached thereto.
The history of skateboards goes back 40 or more years and they have always had truck assemblies attached to their bottom surface. The structure during this period of time has required the fasteners to pass downwardly from the top surface of the skateboard deck and into the structure of the truck assembly. As a final assembled skateboard, there has always been a portion of the mechanical fasteners extending upwardly from the top surface of the skateboard deck.
It is an object of the invention to provide a novel method for manufacturing a skateboard deck with truck mounting inserts therein.
It is also an object of the invention to provide a novel skateboard deck that eliminates any truck fasteners on its top surface.
It is another object of the invention to provide a novel truck mounting insert.
It is an additional object of the invention to provide novel skateboard deck that is economical to manufacture and market.
It is a further object of the invention to provide a novel skateboard deck that can have the skateboard trucks quickly and easily installed or removed.
SUMMARY OF THE INVENTION
The novel skateboard deck and the method of making the same has been designed to eliminate any mechanical fastening structure on the top surface of the skateboard deck. This is accomplished by making the skateboard deck in two distinct stages. During the first stage a plurality of veneer layers of wood are stacked upon each other and a coating of glue is applied between each layer. This stack is then placed in a hydraulic press to form a first block of wood. Next, the first block of wood is positioned in a CNC shaper machine that forms the outline shape of a skateboard deck. Next two sets of four bore holes are drilled completely through the first block of wood. The top end of these bore holes are counter-bored on the initial top surface of the skateboard deck. The truck mounting inserts are then pressed into the bore holes from the initial top surface of the skateboard deck.
The next step involves stacking one or more veneer layers of wood onto the initial top surface of the skateboard deck and applying a coating of glue between each layer. This combined structure is then reinserted in the hydraulic press to form a second block of wood for the second stage in forming the skateboard deck. The second block of wood is then returned to the CNC (computer numerical control) shaper machine for trimming the second block of wood to the same shape as programmed originally. The skateboard deck is then sanded and finished as a regular skateboard. Following this step the two trucks would be installed on the bottom of the skateboard deck using screws that are threaded into the mounting inserts.
