Push broom head and method of fabrication thereof
View Patent ↗A push broom head comprising a base with a leading edge and a trailing edge separated by a width of the base; and tufts of bristles extending from a surface of the base; the tufts of bristles being arranged in rows of bristles of decreasing stiffness from the leading edge to the trailing edge of the base, with a leading row of very stiff bristles and a trailing row of bendable bristles, thereby combining increased ease of handling by a user for an efficient sweeping action, the leading rows loosening and moving heavier particles and the trailing rows loosening and moving finer particles not acted upon by the stiff leading rows.
1. A method for making a push broom head, comprising:
providing a base having a leading edge and a trailing edge;
securing, from the leading edge to the trailing edge of the base, a leading row of bristles of a first stiffness and a trailing row of bristles of a second stiffness; and
securing middle rows of bristles of a third stiffness between the leading row and the trailing row;
wherein the first stiffness is selected between 10 and 20 times larger than the second stiffness and a ratio of a stiffness of the bristles of the middle rows over the second stiffness is selected between about 1.5 and about 20.
2. The method of claim 1 , comprising securing, from the leading edge to the trailing edge of the base, a first leading and a second leading rows of bristles, the second leading row being offset relative to the first leading row along a length of the base; and a trailing row of bristles of a stiffness between 10 and 20 times smaller than a stiffness of the first and second leading rows.
3. The method of claim 1 , comprising further securing a handle on the base.
4. The method of claim 1 , comprising securing, from the leading edge to the trailing edge, at least two leading rows and a trailing row, wherein the bristles of the leading rows amount for about ⅓ of a number of tufts of the broom head.
5. A method for making a push broom head, comprising:
providing a base, the base comprising a leading edge and a trailing edge separated by a width of said base;
securing tufts of bristles extending from a surface of the base;
wherein said securing tufts of bristles extending from a surface of the base comprises arranging tufts of in rows of bristles of decreasing stiffness from said leading edge to said trailing edge of the base, said rows comprising leading rows and trailing rows, a ratio of the rigidity of the bristles of the leading rows over the rigidity of the bristles of the trailing rows being selected in a range between 10 and 20, further comprising securing middle rows between said leading rows and said trailing rows, and securing additional tufts of bristles between the middle rows and the trailing rows, said additional tufts of bristles having a stiffness smaller than the stiffness of the bristles of the trailing rows.
