Abstract
A lightweight plastic transformer pad having upper and lower load bearing walls which are separated by a structurally integrated matrix of transverse support walls extending upwardly from the periphery of an array of apertures in the lower load bearing wall.
Claims5
A lightweight pad providing a semi-rigid vibration dampening support for maintaining an electrical transformer in spaced relation to a generally horizontal plane, said pad comprising in combination:
- a. an integral, monolithic superstructure of synthetic, polymeric members, comprising:
- i. a platform member for contactingly receiving said transformer;
- ii. a base member parallel to said platform member, said base member having a plurality of spaced apertures therein;
- iii. lateral wall members extending peripherally of said pad and enclosing the volume between said platform and said base member;
- iv. a network of hollow, frusto-conical shaped members located between said lateral wall members and extending between said platform member and said base member, said frusto-conical shaped members tapering inwardly from said base member to said platform member and providing frusto-conical-shaped cells having open bases defined by the apertures in said base member and tops defined by, and integral with, said platform member;
- all of said members cooperating to define an internally disposed volume;
- said network of frusto-conical shaped members being substantially regular in pattern;
- v. a transversely extending channel having opposing endwise openings through said base and said platform members to provide physical access between said transformer and said horizontal plane;
- b. low density filler material substantially filling said internally disposed volume;
- and,
- c. means for connectively receiving said electrical transformer in secured relation to said pad.
