Abstract
Mat-base assembly comprises a base including a sheet integrally formed of an elastomeric polymer, a picture frame-like projection formed on the periphery of the sheet and a mat-containing portion formed on the inner side of the peripheral projection, a dust-controlling mat contained in the mat-containing portion and a temporary anchoring mechanism for anchoring detachably the base and mat at a plurality of points on the peripheral edge of the sheet, wherein an anchoring element comprising engaging pieces implanted on a base fabric is fixed to the base, a fiber loop element engageable with the engaging pieces is sewn to the mat and the peripheral portion of the anchoring element is fusion-bonded to the base sheet while in the remaining portion of the anchoring element, the engaging pieces are left as they are. In this mat-base assembly, the durability of the anchoring mechanism is highly improved and good adaptability to the operation of attaching and detaching the dust-controlling mat is maintained for a long time. Furthermore, movement of the dust-controlling mat or roll-up of the corner portion of the mat can effectively be prevented.
