Extension rails for table saws
Extension rails for table saws are disclosed. Some of the disclosed extension rails can be attached to a table saw without a user having to manipulate a lever or knob. Extension rails particularly relevant to portable table saws such as jobsite and bench-top table saws are disclosed, including extension rails that can provide 48″ or more of cutting capacity on jobsite and/or bench-top table saws. A method of attaching extension rails to a table saw is disclosed that does not require the use of a tool or the manipulation of a knob or clamp.
1. A table saw comprising:
a table having a work surface,
a fence,
a front rail associated with the table to support the fence, where the front rail has an end,
a front rail extension, where the front rail extension has an end,
a latch plate extending from either the end of the front rail or the end of the front rail extension,
a socket in the end of the front rail or in the end of the front rail extension, whichever the latch plate does not extend from, where the socket is configured to receive at least a portion of the latch plate, and
a pin associated with the socket,
where the front rail extension is configured to connect to the front rail by the latch plate being inserted into the socket with at least a portion of the front rail extension at an angle above the front rail and above the work surface, and then the front rail extension being lowered to be in line with the front rail and substantially parallel with the work surface, which lowering causes the latch plate to hook around the pin, and
where the front rail extension is configured to be disconnected from the front rail by at least a portion of the front rail extension being raised to be out of line with the front rail and above the work surface, wherein the raising of the front rail extension causes the latch plate to cease to hook around the pin, and then the latch plate being removed from the socket with at least a portion of the front rail extension at an angle above the front rail.
2. The table saw of claim 1 , where the latch plate extends from the front rail extension.
3. The table saw of claim 1 , where gravity contributes to holding the latch plate around the pin.
4. The table saw of claim 1 , further comprising a pin associated with the latch plate, where the latch plate is configured to pivot around the pin.
