Abstract: A collapsible table and chair apparatus 10 including a pair of table top halves 20, 21 pivotally associated with two pairs 32 and 33 of support legs that are pivotally secured to one another. A seat member 40 pivotally associated with one of the pairs 32 of support legs and provided with means 42 for maintaining the seat member 40 in a fixed position relative to the pair of support legs 32 when the apparatus 10 is deployed in the operative mode.

Abstract: A workpiece clamping apparatus for securing a workpiece relative to a planar support surface has a first cam with an arcuate exterior surface thereon. A pin is disposed for rotationally mounting the first cam about an axis. A mounting member is associated with the planar support surface for receiving the pin. Additionally, an abutment plate is operatively associated with the first cam for releasable securing a workpiece relative to the planar support surface. The workpiece can also include a second cam, having an arcuate exterior surface operably attached to the pin. The mounting member has a plurality of spaced apertures arranged in rows on the planar support surface, wherein each of the apertures are dimensioned to receive the pin.

Abstract: A workpiece clamping apparatus has a first cam with an arcuate exterior surface thereon. A pin is provided for rotationally mounting the cam about an axis to an anchoring member. An adjusting mechanism is provided for adjusting the position of the pin means with respect to the anchoring member.A second cam is operably attached to the pin and is mounted for rotation about the axis.An anchoring member is attached to the work surface.A track member is attached to the work surface and the bottom of the anchoring member is attached to the track member.

Abstract: A workpiece clamping apparatus for securing a workpiece relative to a planar support surface; wherein, the workpiece clamping apparatus includes an abutment plate having means for selectively positioning the abutment plate relative to the planar support surface; and, securing means operatively associated with the planar support surface for captively engaging the workpiece between the abutment plate and the securing means.
