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 14):
A table saw, comprising:\n a working surface that includes\n a front edge and a rear edge extending along a longitudinal axis; and \n an opening for a blade oriented perpendicularly to the front and rear edges; \n a pair of stationary rails mounted along the front and rear edges of the working surface, respectively, each stationary rail including a guide surface extending along the longitudinal axis and configured to support and guide a rip fence; and a pair of extension rails, each extension rail having a further guide surface matched to the guide surfaces of the stationary rails; wherein the stationary rails and extension 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 so that the further guide surfaces of the extension rails extend the guide surfaces of the stationary rails; and wherein the connecting end in the common connection interface includes a connection mechanism configured to:\n urge the connecting end together with the supporting end to form an internal connection; and \n align the guide surfaces of the connected rails to as to be co-planar with each other, \n wherein, in the common connection interface:\n the connecting end further includes an internal support member extending along the longitudinal axis; \n the supporting end is configured to be received in the connecting end and to support the internal support member in the connecting end; \n the connection mechanism includes:\n a locking member positioned within the connecting end; and \n an actuator located externally with respect to 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, and \n \n wherein, when the first supporting end is received in the first connecting end, movement of the locking member toward the internal support member moves the locking member into engagement with the supporting end.
