DESCRIPTION:
BRIEF SUMMARY
This invention relates to worktable systems of multi-functional use in connection with building work, carpentry and the like.
Known, easily transportable systems for the clamping and handling of workpieces and/or the support or guidance of power tools are limited in their capacity to deal with larger work material. They are also limited in their versatility; clamping tables do not provide adequate saw table functions, saw tables do not provide adequate clamping table functions and neither provide drill table functions.
In general terms the present invention addresses itself to providing an integrated system in which the worktable is a clamping table and/or a saw table and/or a drill table for example, in which the capacity to handle larger material in all the mentioned functions is more than double that of known systems and in which for easy carrying and transport the folding system is more compact than that of known apparatus.
According to the present invention there is provided a worktable system comprising a supporting structure and two or more sections of planar worktop, two of which may serve as the jaws of a clamp, the said sections being unattached, directly or indirectly to any fixed point on the supporting structure such that in the terms of this invention they are "freely displaceable" along the length of the supporting structure and may be locked in any selected position along that length. The means of tightening forward one or both work top sections, in their function as the jaws of a clamp, is carried together with the displacement of the said sections and takes place from the selected locked position.
In the terms of this invention the "supporting structure" would normally comprise a top support with leg support structure but it could comprise of a top frame only.
Another aspect of the present invention provides a worktable system comprising a supporting structure and displaceable worktop sections in which one or more of the sections is provided with a channel or channels and elements for clamping, machining or other purposes which may be inserted into the said channels.
From another aspect the invention provides a worktable system comprising a supporting structure and displaceable worktop sections in which one or more of the sections may have attached to it power tools, this tool plate section being selectively placed and locked into position to provide with the other section or sections the most suitable support for a work piece, comprising also of elements associated with power tool operations which may use the other section or sections as a fixing point and/or guidance means.
From another aspect the invention provides a worktable system comprising a supporting structure and displaceable worktop sections and means for power tool guidance in the form of a straight edge which may be attached to one of the worktop sections and pivoted to any selected angle traversing the work piece, comprising also of means for aligning and clamping the work piece.
From another aspect the invention provides an articulated tool support and/or guidance system which attached to the supporting structure of the worktable may span the worktop sections or attached to a worktop section or sections may span a portion of their surface, the worktop sections supporting the work piece under the articulated tool support, comprising also of means for aligning and clamping the work piece.
From another aspect the invention provides a worktable system comprising a supporting structure, a worktop secured to it and a plurality of extension pieces releasably securable to said supporting structure, the proximal end being adjustably brought within the volume of the worktable, the distal end having a leg support, the said extension pieces being joined by a cross-member which supports the work piece.
From another aspect the invention provides a worktable system comprising a supporting structure and displaceable worktop sections in which the leg supports fold inward towards each other and in which the worktop sections may be removed f
