Method of molding a cleaning device with a squeegee
View Patent ↗The invention relates to cleaning devices adapted to sweep floors with an attached squeegee, and to methods of manufacturing such cleaning devices. In one embodiment of the invention, a squeegee blade may be molded out of a first material. Subsequently, a head member may be molded, out of a second material of greater hardness than the first material, to a first portion of the previously molded squeegee blade. Bristles and a handle may be attached to the head member.
1. A method of manufacturing a cleaning device adapted to sweep floors comprising:
molding a squeegee blade out of a first material;
providing a mold insert including a slot;
providing a mold including a mold cavity;
placing a first portion of the molded squeegee blade into the slot of the mold insert with a second portion of the molded squeegee blade exposed externally of the mold insert;
placing the mold insert with the molded squeegee blade therein into the mold cavity;
subsequently molding a head member, out of a second material of greater hardness than said first material, to the second portion of said previously molded squeegee blade by adding the second material to the mold cavity;
attaching bristles to said head member; and
attaching a handle to said head member.
2. The method of claim 1 wherein the method is for manufacturing a broom.
3. The method of claim 1 wherein during the step of molding said squeegee blade, said squeegee blade is molded using rubber.
4. The method of claim 1 wherein during the step of molding said head member, said head member is molded using plastic.
5. The method of claim 1 wherein during the step of molding said head member, the first portion of said squeegee blade protrudes from a side surface of said head member.
6. The method of claim 1 wherein during the step of molding said head member, said head member is molded so that a side surface of said head member is defined by a slot.
7. The method of claim 6 wherein during the step of molding said head member, the second portion of the squeegee blade is disposed within said slot of said head member and the first portion of said squeegee blade protrudes out of said slot of said head member.
8. The method of claim 1 wherein during the step of attaching bristles to said head member, said bristles are attached to a bottom surface of said head member.
9. The method of claim 1 wherein during the step of molding said head member, said head member is molded so that a top surface of said head member is defined by a socket.
10. The method of claim 9 wherein the step of attaching a handle to said head member comprises inserting a handle into said socket.
11. A method of manufacturing a broom for sweeping floors comprising:
molding a squeegee blade out of a first material;
providing a mold insert including a slot;
providing a mold including a mold cavity;
placing a first portion of the molded squeegee blade into the slot of the mold insert with a second portion of the molded squeegee blade exposed externally of the mold insert;
placing the mold insert with the molded squeegee blade therein into the mold cavity;
subsequently molding a head member around the second portion of said previously molded squeegee blade with the first portion of said squeegee blade protruding from a side surface of said head member, wherein said head member is molded to have a socket at a top surface of said head member, and said head member is molded out of a second material of greater hardness than said first material;
attaching bristles to a bottom surface of said head member; and
inserting a handle into said socket of said top surface of said head member.
12. The method of claim 11 wherein during the step of molding said squeegee blade, said squeegee blade is molded using rubber.
13. The method of claim 11 wherein during the step of molding said head member, said head member is molded using plastic.
14. The method of claim 11 wherein during the step of molding said head member, said head member is molded so that a side surface of said head member is defined by a slot.
15. The method of claim 14 wherein during the step of molding said head member, the second portion of the squeegee blade is disposed within said slot of said head member and the first portion of said squeegee blade protrudes out of said slot of said head member.
