TOPS
Tops shall be constructed of an aircraft grade, honeycomb structural
core of polypropylene plastic. Cells within the core shall not exceed "
spacing to ensure uniform support to the top surface. The table top
shall be internally supported near the perimeter by a 1 13/16" high, 18
gauge, formed steel channel frame The exterior surfaces of the table
shall be constructed of thermoformed, ABS plastic material, permanently
bonded to the honeycomb core with epoxy adhesive. Edges of the table top
are protected against impact with a profile extrusion of high-impact,
PVC plastic molding that interlocks with and is permanently bonded to
the ABS exterior of the table with epoxy adhesive. The molding shall
incorporate a 5/32" thick bumper edge, backed by a tubular shaped,
impact-absorbing reinforcement. There shall be no less than five layers
of plastic to protect the edges of the table top. Corners of rectangular
models are protected with rib reinforced, injection molded, PVC plastic
sections that interlock with the edge molding.
LEG
ASSEMBLIES
Leg assemblies shall be wishbone style, constructed with one piece load
bearing vertical members of 1" diameter, 16 gauge steel tubing. Legs
shall be capped with high impact plastic glides, secured with internal
spring steel grippers. Tables less than 48" in length or diameter shall
be furnished with independent folding legs of 1.05" diameter, 14 gauge
steel tubing. Comfort Leg assemblies shall be constructed of 1"
diameter steel tubing and shall provide a minimum of 9"of free knee
space on 18" wide tables.
LEG BRACE
MECHANISMS
Folding leg braces shall be constructed of 7/8" wide, 1/8" thick edge
radiused steel. Coil-spring actuated, case hardened steel poppits shall
engage mating holes in the brace to secure the brace automatically when
it is opened. Leg braces shall be attached to leg assemblies and pivot
bracket by the use of steel shoulder rivets.
LEG AND
BRACE ATTACHMENT
Legs and leg braces shall be anchored securely to the table top with a
minimum of 32 fasteners. Self-drilling fasteners are to be held in place
by 18 gauge steel anchor plates that are epoxy bonded to the
polypropylene core and ABS bottom sheet of the table top.
METAL
FINISH
All leg assemblies shall be thoroughly cleaned and phosphatized to
enhance paint adhesion. Metal parts shall be then finished with a
thermofused epoxy powdercoating.
WARRANTY
NNLW Series Folding Tables shall be covered by a 15-year warranty. |
