Abstract:
A table saw includes a working surface and a rail system. The rail system includes stationary rails mounted along the working surface, and extension rails. The rails each include matching guide surfaces extending along the longitudinal axis and configured to support and guide a rip fence. The rails have a common connection interface that in each case includes a connecting end and a supporting end, such that the extension rails are mountable with the stationary rails. When mounted, the guide surfaces of the extension rails extend the guide surfaces of the stationary rails. The connecting end in the common connection interface includes a connection mechanism configured to urge the connecting end together with the supporting end to form an internal connection, and to align the guide surfaces of the connected rails to as to be co-planar with each other.

Claim (Index 8):
A rail system for a table saw, comprising:\n a first rail that includes:\n a first guide surface extending along a longitudinal axis; and \n a first supporting end; and \n a second rail that includes:\n a second guide surface matching the first guide surface and extending along the longitudinal axis; and \n a first connecting end having a connecting mechanism configured to:\n urge the first connecting end together with the first supporting end to form an internal connection, such that the second rail is mounted with the first rail; and \n align the second guide surface so as to be co-planar with the first guide surface, \n \n wherein:\n the second rail further includes an internal support member extending along the longitudinal axis; \n the first supporting end of the first rail is configured to be received in the first connecting end and to support the internal support member when the second rail is mounted with the first rail; and \n the connection mechanism includes:\n a locking member positioned within the first connecting end; and \n an actuator located externally with respect to the second rail and the first connecting end and configured to be manually operated by a user of the rail system, the actuator being operable by the user to move the locking member toward and away from the internal support member, \n \n wherein, when the first supporting end of the first rail is received in the first connecting end of the second rail, movement of the locking member toward the internal support member moves the locking member into engagement with the first supporting end.
