Abstract
Abstract A power tool (10) has a working assembly (20) mounted on a first side of a table (16). The table is pivotable about an axis (41) with respect to a frame (14) between two working dispositions. A working head (eg blade 32) of the assembly (20) is positionable through an aperture in the table so that it can work on workpieces supported above either side of the table. The table is connected to the frame through an intermediate member (46) which is pivoted to the frame. The table has a first wheel (40) fixed thereto and a belt passes around the first wheel and around a second wheel (50) fixed to the frame (14) around the pivot (51) of the intermediate member. Pivoting of the intermediate member relative to the frame rolls the first wheel inside the belt and rotates the table between bench mode (Figure 2) and snip-off mode (Figure 3). <IMAGE>

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
76 words
A power tool (10) comprising a frame (14), a table (16) mounted on the frame, a working assembly (20) mounted on one side (16a) of the table and a pivot system (18), said pivot system enabling the table to pivot between two dispositions thereof with respect to the frame about an axis (41) characterised in that said axis is movable in the frame in a transverse direction with respect to said axis between two positions (41a,41b).
Claim 2
Dependent Claim
27 words
A power tool as claimed in claim 1, characterised in that said axis is movable between said two positions in an arc (41c) mostly above the table.
Claim 3
Dependent Claim
27 words
A power tool as claimed in claim 1 or 2, characterised in that said axis is movable in response to pivoting of the table about said axis.
Claim 4
Dependent Claim
36 words
A power tool as claimed in claim 3, characterised in that said axis is movable between said positions simultaneously with pivoting of the table between said dispositions about said axis through 180° relative to the frame.
Claim 5
Dependent Claim
38 words
A power tool as claimed in any preceding claim, characterised in that said axis is adapted to move from a position (41a) above the level of the table to a position (41b) below the level of the table.
Claim 6
Dependent Claim
33 words
A power tool as claimed in any preceding claim, characterised in that said pivot system comprises an intermediate member (46) which is pivoted to the table about said axis and to the frame.
Claim 7
Dependent Claim
42 words
A power tool as claimed in claim 6, characterised in that the table (16) has a first wheel (40) fixed thereto around said axis and rotation means (48,50) in the frame arranged to rotate the wheel when it moves between said positions.
Claim 8
Dependent Claim
40 words
A power tool as claimed in claim 7, characterised in that said rotation means comprises a belt (48) around said first wheel and around a second wheel (50) fixed around the pivot (51) of said intermediate member to said frame.
Claim 9
Dependent Claim
49 words
A power tool as claimed in claim 8, characterised in that the first and second wheels are dimensioned so that, given the extent of the pivot of said intermediate member relative to the frame between said two positions of said axis, the first wheel and table rotate through 180°.
Claim 10
Dependent Claim
53 words
A power tool as claimed in claim 9, characterised in that said first wheel is mounted on said one side of the table, said wheels and intermediate member being arranged so that said sides (16a,b) of the table are at the same level in the frame in the two dispositions of the table.
Claim 11
Dependent Claim
24 words
A power tool as claimed in any preceding claim, characterised in that it includes catch means (60,70,76) to lock the table in either disposition.
Claim 12
Dependent Claim
44 words
A power tool as claimed in claim 11, characterised in that the frame has a catch member (60,70) at both ends of the frame adapted to catch and support a front edge (16c) of the table in either of the dispositions of the table.
Claim 13
Dependent Claim
29 words
A power tool as claimed in any preceding claim characterised in that it further comprises limit means (66a,b) to limit movement of said axis to between said two positions.
Claim 14
Dependent Claim
34 words
A power tool as claimed in claim 13 when dependent on claim 6, characterised in that said limit means comprises stops (66a,b) in the frame against which said member abuts in said two positions.
Claim 15
Dependent Claim
42 words
A power tool as claimed in any preceding claim, characterised in that a working head (32) of the working assembly is positionable through an aperture in the table so that it can work on workpieces supported on either side of the table.
Claim 16
Dependent Claim
26 words
A power tool as claimed in claim 15, characterised in that said working assembly is a circular saw pivoted to said one side of the table.
Claim 17
Dependent Claim
35 words
A power tool as claimed in claim 7 or in any of claims 7 to 16 when dependent on claim 7, characterised in that said first wheel comprises two half-shells (40a,b) surrounding said intermediate member.
Claim 18
Dependent Claim
35 words
A power tool as claimed in claim 8 or in any of claims 9 to 17 when dependent on claim 8, characterised in that said second wheel comprises two half-shells (50a,b) surrounding said intermediate member.
