Drawing table and easel conversion

Claim 2

A folding table comprising: A. at least two pairs of first and second pivotally attached crossed legs, joined by transverse brace members to form a folding base; B. stop means defining the limit of unfolding of said base; C. a removable tabletop having a top surface, a bottom surface, first and second opposed edges, and a central portion between said edges; D. first rack means extending along the upper ends of said first legs; E. a strut having one end pivotally attached to said tabletop bottom surface near said first edge and the other end received by said first rack means to support said first edge; F. second rack means extending along the bottom surface of said tabletop substantially from said second edge to said central portion; and G. a transversely extending bar supported by the upper ends of said second legs and received by said second rack means to support said econd edge.

Claim 3

The folding table of claim 1, wherein said strut telescopes, whereby to change the elevation of the first edge of said tabletop while said base remains unfolded to its limit of unfolding.

Claim 4

The folding table of claim 1, wherein said second legs telescope, whereby to change the elevation of the second edge of said tabletop while said base remains unfolded to said limit.

Claim 5

The folding table of claim 3, wherein said telescoping second legs further comprise lower members provided with longitudinal channels, upper members received in said channels for parallel sliding displacement and supporting said transversely extending bar, and brake means releasably fixing said upper and lower members together.

Claim 6

The folding table of claim 4, wherein said brake means comprises: A. a pair of lips on each lower member confining each upper member in its channel, each said pair of lips having inner surfaces for being borne against by said upper members and opposed outer surfaces, the outer surfaces of the respective pairs of lips being inwardly opposed; B. a spacer bar having its respective ends attached to said upper members near their lower ends; C. a pressure plate for each upper member having an outer face for bearing against the outer surfaces of said pair of lips and a collar perpendicular to said outer face bored to receive said spacer bar therethrough; D. a tubular release bar carried on said spacer bar and having a first end threadably received by one said collar and a second end bearing against the opposite pressure plate and received in the corresponding collar; and E. means to prevent said pressure plates from rotating with respect to said upper members; whereby rotation of said release bar urges said pressure plates and upper members together against said pairs of lips to fix said upper members and lower members together, and whereby counterrotation of said release bar releases said upper members for sliding displacement relative to said lower members.

Claim 7

The folding table of claim 1, wherein said tabletop can be raised to a substantially vertical position for use of said folding table as an easel.

Claim 8

The folding table of claim 6, further comprising removable intermediate stop means to fix said crossed legs in a position between their fully folded and fully unfolded positions.

Claim 9

The folding table of claim 6, further comprising ledge means for mounting adjacent one of said first and second edges and keeper means for mounting adjacent the other of said first and second edges.

Claim 10

The folding table of claim 8, wherein said keeper means can be removed from said tabletop when not in use.

Claim 11

The folding table of claim 8, wherein said keeper means is mounted on a slide received in a track fixed to the bottom surface of said tabletop, whereby to support said keeper at various points beyond the edge of said tabletop.

Claim 12

The folding table of claim 8, wherein said ledge is slidable up or down along said tabletop.

Claim 13

The folding table of claim 11, wherein said tabletop top surface includes a third rack disposed in the direction of travel of said ledge and support means to support said ledge at a desired position along said third rack.

Claim 14

The folding table of claim 1, further comprising a side table fixed to an upper portion of one of said legs.

Claim 15

The folding table of claim 1, further comprising a draw box and drawer assembly and means supporting said assembly from said transversely extending bar for access from beneath said tabletop.

Claim 16

An easel comprising: A. at least two pairs of first and second pivotally attached crossed legs, joined by transverse brace members to form a folding base; B. stop means defining the limit of unfolding of said base; C. a removable easel body having a top surface, a bottom surface, first and second opposed edges, and a central portion between said edges; D. a transversely extending bar supported by the upper ends of said second legs; E. means mounted to said easel body bottom surface between said central portion and said first edge to engage said transversely extending bar; F. means to support said second edge against the lower ends of said first legs; and G. table support means positioned substantially adjacent said first and second edges to receive the tops of said first and second legs when said easel body is supported substantially horizontally thereon, wherein said table support means includes: first rack means extending along the upper ends of said first legs; a strut having one end pivotally attached to said easel body bottom surface near said first edge and the other end received by said first rack means to support said first edge; and second rack means extending along the bottom surface of said easel body substantially from said second edge to said central portion, adapted to engage said transversely extending bar to support said second edge; whereby to support said easel body for use as a tabletop.

Claim 17

An easel comprising: A. at least two pairs of first and second pivotally attached crossed legs, joined by transverse brace members to form a folding base; B. stop means defining the limit of unfolding of said base; C. a removable easel body having a top surface, a bottom surface, first and second opposed edges, and a central portion between said edges; D. a transversely extending bar supported by the upper ends of said second legs; E. means mounted to said easel body bottom surface between said central portion and said first edge to engage said transversely extending bar; F. means to support said second edge against the lower ends of said first legs; and G. table support means positioned substantially adjacent said first and second edges to receive the tops of said first and second legs when said easel body is supported substantially horizontally thereon, wherein said table support means includes: first rack means extending along the upper ends of said first legs; a strut having one end pivotally attached to said easel body bottom surface near said first edge and the other end received by said first rack means to support said first edge; and second rack means extending along the bottom surface of said easel body substantially from said second edge to said central portion, adapted to engage said transversely extending bar to support said second edge; whereby to support said easel body for use as a tabletop.
