Abstract A work support. The support has a cross member of variable length to receive and support planks of variable width. Leg supports extend downwardly and outwardly from each end of the cross member. There are stops attached to the cross member, adjacent each end, to locate each side of a plank carried by the cross member. The plank can be located on the cross member and legs are supported in the leg supports.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
94 words
A work support comprising: a cross member of variable length for receiving and supporting at least one supported member, the cross member being in two separable sections, one section being adapted to telescope within the other; means for enabling said two sections to be held in a fixed spaced apart relationship whether or not telescoped together; leg support means extending downwardly and outwardly from each end of the cross member; respective stops fixedly attached to each of said sections adjacent an end thereof; and means to hold a leg in each leg support means.
Claim 2
Dependent Claim
94 words
A work support comprising: a cross member of variable length for receiving and supporting at least one supported member, the cross member being in two separable sections, one section being adapted to telescope within the other; means for enabling said two sections to be held in a fixed spaced apart relationship whether or not telescoped together; leg support means extending downwardly and outwardly from each end of the cross member; respective stops fixedly attached to each of said sections adjacent an end thereof; and means to hold a leg in each leg support means.
Claim 3
Dependent Claim
42 words
A work support as claimed in claim 1, wherein said enabling means comprises holes provided in each section of said cross piece, at least some of said holes enabling engagement of each section with a spacing member defining said spaced apart relationship.
Claim 4
Dependent Claim
34 words
A work support as claimed in claim 2, wherein said holes are provided at least in the stops of each of said sections for engaging with a support member acting as said spacing member.
Claim 5
Dependent Claim

A work support as claimed in claim 3, wherein each of said sections includes a channel portion, the channel portion of one of said sections being slidable within the channel portion of the other of said sections and wherein said holes are also provided in said channel portions.
Claim 6
Dependent Claim
34 words
A work support as claimed in claim 1 in which the leg support means are channels opening outwardly from said cross member and are adapted to receive a leg of generally rectangular cross section.
Claim 7
Dependent Claim
92 words
A work support as claimed in claim 5 in which the means to locate a leg in each leg support means comprises a bracket pivotally attached to each channel on a wall of the channel remote from the open, outwardly disposed side and extending round and across the open face of the channel to contact and retain a leg held in the channel; a lever extending inwardly from the bracket to permit hand movement of the bracket; and resilient means urging the bracket to a position in which it locates a leg.
Claim 8
Dependent Claim
27 words
A work support as claimed in claim 1 in which the leg support means comprises a housing adapted to surround a leg of generally rectangular cross section.
Claim 9
Dependent Claim
85 words
A work support as claimed in claim 7 including a cam member pivotally attached to an inner face of the housing; an opening in said inner face whereby the cam can project into the housing; a lever to permit rotation of the cam between a first position where a leg may be inserted into the housing without obstruction to a second position where a leg in the housing is forced outwardly by the cam, against an outer surface of the housing, to locate the leg.
Claim 10
Dependent Claim
38 words
A work support as claimed in claim 1 in which the stops attached to each cross member are angle bars located with one limb of the angle extending upwardly to abut a side of a supported member plank.
Claim 11
Dependent Claim
