Ergonomically adjustable needlecraft support structure

A free-standing, adjustable needlecraft support and pattern holding device of an ergonomically adaptable design, the improvement comprising in combination:

• A) a three part base and leg assembly of a wooden construction comprising;
• 1) a first narrow longitudinal horizontal part, of a profile to permit passage under furniture, having a cut-out portion at approximately one-quarter of the length thereof for conjunctive engagement with;
• 2) a second transverse horizontally disposed stabilizing part, of a profile higher than said first part at approximately one-quarter of the length thereof a cut-out portion for mating engagement with said first part and;
• 3) a third vertically rising support leg part of a narrow isosceles triangular configuration, which is truncated and rounded at a point short of the apex thereof, the base of which is matingly engagable with said first part and said second part, said three parts being provided with corresponding bores therethrough to accommodate;
• B) conjoinment means whereby said longitudinal transverse and vertical parts are joined together by a plurality of threaded mechanical fasteners passing through said corresponding bores to form a rigid unitary construction, said construction being configured for reversible assembly to accommodate the requirements of right or left handed persons further comprises;
• C) a vertical extension member, having a saddle-like cut-out portion, including a dimensioned horizontal bore therethrough at the lower end thereof, providing for non-adjustable, cooperative attachment to, or removal from, the upper truncated and rounded extremity of said rising support leg, said vertical extension member having a vertical dimensioned bore provided with internal metallic threads at the center of the distal, or upper truncated end thereof, to accommodate the rotatable and frictionally adjustable and lockable attachment of;
• D) a horizontal outwardly extending swivel arm, having a centralized, dimensioned, vertical bore adjacent the proximal end thereof, to accommodate the passage therethrough of a knobbed, externally threaded, metallic fastener into operable engagement with the said internal metallic threads of said vertical extension member, for it's rotatable and frictionally adjustable and lockable attachment, upon and to, said vertical extension member, said arm having adjacent the distal or opposing end thereof, a second vertical, dimensioned bore, passing through the center of its width to accommodate the passage therethrough, (from the opposing direction) of a second knobbed, externally threaded, metallic fastener provided for retention, operable engagement, rotation and frictional adjustment and locking of;
• E) a book or pattern support having a correspondent dimensioned vertically disposed bore, comprising metallic internally threaded means therein, at the center of the length thereof, for operable engagement with the threaded end of said knobbed, externally threaded, metallic fastener means and is thereby mechanically engaged for retention, horizontal rotation upon, or frictional adjustable and locking to, said outwardly extending swivel arm;
• F) an adjustable work support arm attached to, and extending outwardly from the point of conjunction with the upper extremity of said vertical support leg and said vertical extension member, said work support arm being angularly adjustable in the vertical plane and frictionally adjustable and lockable by threaded means, to accommodate the ergonomic, physical and comfort requirements of the user;
• G) a work-piece holding clamp, comprising a fixed jaw having a cork-lined gripping surface and a screw-operated movable jaw having a similar gripping surface, movable in a short arcuate path, relative to said fixed jaw, to cooperatively grip irregular work-pieces, said clamp being attached in frictionally adjustable and lockable rotational engagement to the distal or outermost end of said work support arm;
• H) the frictionally adjustable and lockable conjointment means comprising cooperative metallic, internally and externally threaded means.
