Abstract

Abstract A work table having a table top with a uniform planar upper surface, truncated corners and a frame on the underside thereof. Depending from the frame are corner collar members with a respective tapered bore therein. The table top is supported by corner support posts each of which include recesses at least adjacent to the respective upper ends thereof. A pair of matingly engaging sleeve sections clamp around each support post. The sleeve sections, when joined, provide a corresponding tapered exterior surface. A protusion, internally of the sleeve sections, locks into an associated recess on the support posts. The corner collar members receive the respective pairs of sleeve sections and urge them into secure clamping engagement of the support posts. The work table can include a frame support therebelow or an adjustable shelving therebelow.

A work table comprising: a table top; corner support posts for supporting said table top, recesses being provided on each post adjacent respective upper ends thereof; a pair of matingly engaging sleeve sections for clamping about each support post, said sleeve sections being joined to provide a tapered exterior surface, protruding means being provided internally in each of said sleeve sections for locking into an associated one of said recesses on said support posts; corner collar members having a respective tapered bore therein, said corner collar members being secured to an underside of said table top for receiving respective pairs of said sleeve sections and urging them into a secure clamping engagement on said support posts; a support frame secured onto said underside of said table top, said collar members depending from said support frame; and said support frame including a pair of elongated, side channel members, and a pair of elongated end angle members interconnecting said side channel members and closing off their respective open ends so as to provide a closed support frame.
Claim 2
Dependent Claim 175 words
A work table comprising: a table top; corner support posts for supporting said table top, recesses being provided on each post adjacent respective upper ends thereof; a pair of matingly engaging sleeve sections for clamping about each support post, said sleeve sections being joined to provide a tapered exterior surface, protruding means being provided internally in each of said sleeve sections for locking into an associated one of said recesses on said support posts; corner collar members having a respective tapered bore therein, said corner collar members being secured to an underside of said table top for receiving respective pairs of said sleeve sections and urging them into a secure clamping engagement on said support posts; a support frame secured onto said underside of said table top, said collar members depending from said support frame; and said support frame including a pair of elongated, side channel members, and a pair of elongated end angle members interconnecting said side channel members and closing off their respective open ends so as to provide a closed support frame.
Claim 3
Dependent Claim 55 words
A work table as in claim 1, wherein said collar members extend from said side channel members with said tapered bores in said collar members extending entirely therethrough to communicate with a space provided within each of said channel members, said upper ends of the support posts projecting into the spaces within said channel members.
Claim 4
Dependent Claim 22 words
A work table as in claim 1, wherein said support frame is inwardly spaced from a peripheral edge of said table top.
Claim 5
Dependent Claim 33 words
A work table as in claim 1, and further comprising a downwardly depending skirt peripherally provided about said table top, and a peripheral lip inwardly extending from a distal end of said skirt.
Claim 6
Dependent Claim 25 words
A work table as in claim 4, wherein said said table top includes truncated corners, and wherein said skirt is continuous around said truncated corners.
Claim 7
Dependent Claim 33 words
A work table as in claim 1, wherein said table top has a planar upper surface, said upper surface being a unitary sheet throughout so as to avoid any cracks or crevices therein.
Claim 8
Dependent Claim 14 words
A work table as in claim 1, wherein said collar members are tapered sleeves.
Claim 9
Dependent Claim 80 words
A work table as in claim 1, wherein said corner posts are provided with spaced apart recesses along substantially their entire length, and further comprising a lower shelf having truncated corners, corner connectors coupled to each truncated corner, each corner connector having a tapered bore therethrough, and a pair of said matingly engaging sleeve sections associated with each of said corner connectors to securely retain said lower shelf in a supported position at a desired location on said support posts.
Claim 10
Dependent Claim 93 words
A work table as in claim 1, wherein each of said channel members includes a pair of legs connected by a bight portion to be U-shaped in cross section, said channel members having connecting arms laterally extending from distal ends of said legs, and said angle members are L-shaped in cross section having a width of one leg thereof at least equal to a height of said channel member to thereby completely seal the open ends of said channel members, the other leg of said L-shaped angle members serving as a connecting leg.
Claim 11
Dependent Claim 32 words
A work table as in claim 9, and further comprising sealing tape interposed between said underside of said table top and said connecting arms and connecting legs to avoid direct contact therebetween.
Claim 12
