Abstract
A squeegee blade includes a mounting plate with a surface. A relatively rigid support member is attached to the surface of the mounting plate and a relatively flexible blade is attached to the surface of the mounting plate adjacent to the support member so that the blade is supported by the support member against compression toward the mounting plate.
Claims17
A squeegee blade comprising:
- a mounting plate having an upper surface and a lower surface;
- a plurality of support members forming a plurality of metal runners attached to the lower surface of the mounting plate generally parallel to each other and to the direction of forward and reverse movement of the squeegee blade and spaced apart from one another laterally across the lower surface of the mounting plate and having a height;
- a flexible continuous vulcanized rubber blades, having a top and a bottom defining a depth, attached at the top to the lower surface of the mounting plate and encapsulating the plurality of runners and adhered to the plurality of runners and the lower surface of the plate, wherein the encapsulated plurality of runners provide vertical support against compression between the top and the bottom to the flexible continuous vulcanized rubber blade.
A squeegee blade for use on construction equipment, the squeegee blade comprising;
- a relatively rigid mounting surface;
- a plurality of relatively rigid supports secured to the mounting surface;
- and
- a relatively flexible blade having a top and a bottom, the top secured to the mounting surface and the relatively flexible blade formed of vulcanized rubber encapsulating and adhered to at least one of the plurality of relatively rigid supports, wherein the at least one encapsulated relatively rigid support extends substantially from the mounting surface to the bottom of the relatively flexible blade so that the relatively rigid support acts to support the relatively flexible blade against compression toward the relatively rigid mounting surface.
