Description

BACKGROUND OF THE INVENTION

The present invention relates to a brush that includes removable plates with tines that can be inserted into a complementary handle. Preferably, the tines are integral with the plates.

Brushes used for applying liquids such as paint, barbecue sauces or even sealant for blacktop driveways are typically manufactured as a complete one-piece assembled unit that is sold with the handle permanently connected to the bristles. After the brush is utilized to coat a particular object with a desired liquid, it is either cleaned or discarded. Cleaning the brushes is difficult when the liquid adheres between the bristles and requires intensive soaking in cleaning solutions to remove the liquid so that the brush can be readied for reuse. Typically, many brushes are so difficult to clean and maintain that they are discarded by the user. Further, food basting brushes that trap food and sauces within the bristles allow bacteria to grow, potentially causing illness. Brushes with bristles that can be removed require complex attachment mechanisms and typically are still difficult to clean after the brushes are disassembled due to the fact that the bristles are still too abundant within the bristle segment to allow for easy cleaning.

Prior art brushes do not provide for a brush having removable integral plates of tines that can be easily assembled and disassembled for cleaning purposes and manufactured in a cost-effective manner.

SUMMARY OF THE INVENTION

The present invention is a brush that comprises removable plates with tines that can be inserted into a complementary handle. The plates, made up of tines connected to a manifold at one end, are retained by the handle. The removable plates are of a unitary construction, and can be rolled, stacked or folded upon one another to form layers of tines. The plates are preferably substantially flat. The plates are designed to be easily separated or flattened after use to allow for cleaning and replacement if the tines should become damaged. The plates may also be interconnected by a set of hinges. The tines further may include a plurality of flutes or ribs that aid in liquid retention when the brush is being used. After use, the plates can be removed from the handle and easily cleaned. Since the plates are manufactured from a unitary piece of material preferably by compression molding, the fabrication costs are low.

These and other aspects of this invention are illustrated in the accompanying drawings and are more fully described in the following specification.

The tines 16 of the brush 10 are part of a series of plates 84 that are stacked or folded together to form layers of tines 16. The plates 84, as shown in FIGS. 3–7, are preferably fabricated from a silicone polymer material that has desirable heat resistance and anti-adhesion properties. In addition to silicone polymers, other polymers may be used to fabricate the plates 84, such as thermoplastic rubbers. The plates 84 include a manifold 86 at a first end 88 and the tines 16 at a second end 90. The tines 16 and the manifold 86 of each plate 84 are of a unitary construction allowing the plates 84 to be fabricated from a single type of material by die cutting, compression molding, injection molding or other molding methods known to those skilled in the art. The preferred compression molding allows the single molded unit to have tines 16 extending from an end of a plate 84 in one integral piece.

FIGS. 3–6 illustrate three plates 84a, 84b and 84c interconnected by living hinges 92a and 92b that allow the plates 84a–c to be folded upon each other to form layers of tines 16. In place of hinges, any jointed or flexible device that allows pivoting may be used. While FIGS. 3–6 illustrate three interconnected plates 84 additional plates 84 may be used to increase the thickness of the brush 10. The three plates 84a–c are preferably molded as one unitary piece, but can be molded as individual plates if desired.
