Worktable

A worktable, comprising:

• a tabletop comprising a pair of fixture receiving frames extending generally parallel, each frame having opposite ends and a center between its ends;
• two pairs of legs for support the tabletop, the legs having top and bottom ends, the leg top ends of one of the legs of each pair of legs being pivotally connected to the tabletop generally toward the center of a respective one of the frames between the ends of that frame, the one leg being pivotable to selectively move the one leg to a support position of the legs wherein the bottom ends of the legs of each pair are separated and to a folded position of the legs wherein the bottom ends of the legs of each pair are toward each other;
• the frames being connected with the respective leg pairs such that the tabletop can be lifted upright while the leg pairs are in the folded position;
• a respective pair of fixtures on each frame, and means in each frame for adjusting the distance between the fixtures on that frame for enabling the clamping of an article between the fixtures on that frame;
• a support arm having an upper end which is pivotally connected to one end of one frame at a location spaced away from the pivot connection of the respective one leg to the one frame, the support arm having a lower end with a dent formed therein;
• a pin formed on the one leg at the one frame and the pin being placed for being received in the dent of the support arm, and such reception of the pin in the dent fixing the legs in their supporting position and fixing the one leg against pivoting to the legs folded position, while separation of the pin from the dent in the support arm frees the one leg to pivot to the legs folded position;
• slidable fixing means on the support arm, the fixing means being slidable from a position opening the dent for permitting the locating pin on the leg to move in and out of the dent to a closed position for locking the pin in the dent;
• each fixture comprising a lower part connected to the top of the respective frame and an upper part pivotally connected to the lower part at a pivot connection for enabling the upper part to be pivoted from a first orientation to a second orientation perpendicular to the first orientation;
• the tabletop further comprising a respective top board attached at a location on each fixture upper part such that pivoting of the fixture upper part moves the board between a flat, generally horizontal orientation and an upright, generally vertical orientation;
• the upper and lower fixture parts each respectively comprising two spaced apart sides, a retaining pin defined on at least one side of the upper part, at least one side of the lower part having a pivot guide slot defined therein, the sides of the upper part being respectively placed outward of the respective sides of the lower part, the retaining pin of the upper part extending from the side of the upper part through the guide slot in the side of the lower part;
• a spring on the retaining pin, means on the retaining pin for being engaged by the spring and those means being biased outwardly by the spring into engagement with at least one side of the lower part for restraining movement of the retaining pin along the guide slot, thereby for restraining pivoting of the upper part with respect to the lower part;
• the pivot connection between the upper and lower parts being spaced from the retaining pin and the guide slot, the guide slot being curved to permit pivoting of the retaining pin along with the pivoting of the upper part.
