Dual sliding rail and locking mechanism for use with a table saw

A table saw having dual sliding rails and locking system, the table saw comprising:

• a frame having an upper surface through which a blade extends to cut a material, the upper surface having a front and a rear edge extending between a first and a second side;
• a front first support bracket secured to the front edge toward the first side of the surface;
• a rear first support bracket secured to the rear front edge toward the first side of the surface;
• a front second support bracket secured to the front edge toward the second side of the surface;
• a rear second support bracket secured to the rear edge toward the second side of the surface;
• an auxiliary surface for extending the upper surface of the frame, the auxiliary surface having a front and rear edge;
• a front auxiliary mounting bracket secured to the front edge of the auxiliary surface;
• a rear auxiliary mounting bracket secured to the rear front edge of the auxiliary surface;
• a front rail having a channel formed in one elongated edge of the front rail, the front auxiliary mounting brackets being placed in the front rail channel towards one end thereof to secure the auxiliary surface to the front rail and the front first support bracket being slidably engaged in the channel towards an opposing end of the rail;
• a rear rail having a channel formed in one elongated edge of the rear rail, the rear auxiliary mounting brackets being placed in the rear rail channel towards one end thereof to secure the auxiliary surface to the rear rail and the rear first and support bracket being slidably engaged in the channel towards an opposing end of the rail, and
• a locking system to lock the extension in a position such that the auxiliary surface can be moved relative the upper surface. the locking system comprising:
• a front locking plate made of spring steel, the front locking plate being slidably arranged within the channel of the front rail and positioned between the first and second front support bracket, the front rail locking plate being laterally movable within the channel between a released position wherein the rail slides relative the first and second front support brackets and a locked position wherein the rail is locked in a position such that the auxiliary table is secured in a position relative the upper surface;
• a rear locking plate made of spring steel, the rear locking plate being slidably arranged within the channel of the rear rail and positioned between the first and second rear support brackets, the rear rail locking plate being laterally movable within the channel between a released position wherein the rail slides relative the first and second rear support brackets and a locked position wherein the rail is locked in a position such that the auxiliary table is secured in a position relative the upper surface;
• a lever;
• a front cam connected to the front locking plates to move the plate;
• a rear cam connected to the rear locking plates to move the plate, and
• a rod connected between the lever and the front and rear cams such that the movement of the lever from a first position in which the locking plates are in the locked position, to a second position moves the rod and thereby moves the cams to move the locking plates to an open position.
