Working surface

A working surface having a substantially continuous supporting surface comprising:

• first and second portions, each having opposite ends, forwardly and rearwardly disposed peripheral edges, and a longitudinal line of reference;
• and
• means mounted on the first and second portions for releasably and matingly interlocking the first and second portions in predetermined, juxtaposed, end-to-end relation thereby positioning the respective longitudinal lines of reference in substantially coaxial alignment and forming a substantially continuous supporting surface, and wherein the interlocking means is disposed on the opposite ends and substantially intermediate the forwardly and rearwardly disposed peripheral edges of the respective first and second portions, and wherein the interlocking means further includes means for aligning the first and second portions in substantially the same plane, the aligning means including a female receiving station which is formed in one end of the first portion, and which has a length dimension which is less than the length dimension of the end of the first portion, and a male member which is made integral with one end of the second portion, and wherein the respective female receiving station and male member having complementary shapes, and wherein the interlocking means further includes a plurality of ribs which are made integral with the female receiving station and the male member respectively, and wherein the respective ribs are disposed in predetermined spaced, substantially parallel relation relative to each other and with the supporting surface, and wherein the respective ribs define channels therebetween which each have predetermined cross-sectional shapes and dimensions, and wherein the respective ribs made integral with the female receiving station, and male member, are disposed in predetermined positions such that each rib may be received in one of the channels formed in the other portion thereby forming a substantially continuous surface and fixing the first and second portions in end-to-end relation.

A working surface comprising:

• first and second portions each having a supporting surface, a peripheral edge, including forwardly and rearwardly disposed portions, and first and second ends respectively, and wherein the second end of the first member is disposed in juxtaposed relation relative to the first end of the second member;
• a female receiving station formed in the peripheral edge and second end of the first member, and wherein the receiving station includes first and second rib members which are individually disposed in predetermined spaced relation relative to the supporting surface of the first member and to each other, the individual ribs oriented in planes which are substantially parallel to the plane of the supporting surface;
• a male member made integral with the peripheral edge and first end of the second portion and which is operable to releasably mate with the female receiving station, the male member including three spaced ribs which are individually oriented in planes which are substantially parallel to the plane of the supporting surface of the second portion;
• and
• a raised edge member positioned along the rearwardly disposed peripheral edge of the first and second portions respectively, and wherein the first and second portions of the working surface, when disposed in mating relation provides a substantially continuous supporting surface, and wherein the raised edge members operates as a barrier to prevent an object of interest from falling off the rearward peripheral edge.
