Abstract
A surface sweeping broom in which the handle is attached to an elongated brush head of circular cross-section. The brush head contains a cylindrical inner core overlaid with a molded thermoplastic brushing surface. The molded brushing surface is comprised of a base or matrix and fingerlike projections which are integrally fused with the matrix and extend vertically from it. In one embodiment, the brush head is provided with a centered bore which extends completely through it. The bore is threaded to secure a handle member which can be inserted at either end of the bore. Thus, when a brushing surface becomes worn, the handle can be reversed. In this manner, all four quadrants of the circular brushing surface can be effectively utilized.
Claims3
A broom assembly for sweeping litter from large surface areas which comprises in combination:
- a. a handle member;
- b. an elongated brush head of circular cross-section characterized by:
- i. an inner cylindrical support core;
- ii. a molded, thermoplastic, brushing surface circumferentially mounted on said support core;
- iii. a centrally disposed bore which extends through the entire width of the brush head, with the bore being adapted for receiving and engaging said handle member at either end of the bore;
- c. said molded, thermoplastic, brushing surface being characterized by:
- i. a matrix consisting of spaced apart parallel strips;
- and
- ii. clusters of vertically extending projections which are spaced apart between said parallel strips and wherein each cluster of projections arises from a cup-shaped supporting base which is integrally fused with adjacent parallel strips of said matrix to form a bridge therebetween.
