BRIEF SUMMARY
FIELD OF THE INVENTION

The field of this invention relates generally to cleaning devices for contacting a surface to be cleaned.


BACKGROUND OF THE INVENTION

It is known in the field of carding devices to utilize wire clips mounted in closely set rows in various belting materials fastened to the back for carding fibers. However, such carding devices are not used in grinding or contacting a surface to remove rust, paint, etc. Further the wires in such carding devices do not include the use of a wear resistant coating.
Wire brushes are presently used to abrade a surface. Generally, such wire brushes have a plurality of wires mounted with a rigid frame and the wires mounted therein are designed to flex in response to the abrasive action between the surface and the wire brush such that the wire drags across the surface to be cleaned.


SUMMARY OF THE INVENTION

The cleaning device of the present invention includes a plurality of bent wires mounted in a resilient member. The resilient member may be further adapted for connection with a drive unit to drive both the resilient member and the bent wires relative to a surface to be cleaned. During such movement the engagement of the bent wires with the surface to be cleaned causes the leading edge of each bent wire to be directed toward the direction of movement of the mounting member.
In the present invention, fatigue failures of the wires are reduced because the resilient member permits a pivoting type movement of the bent wires in the resilient mounting member. As such, a stiffer wire can be utilized to effect more rapid cleaning of a surface. Moreover, the wire retains an angle with respect to the direction of abrasion such that the wire contacts the surface in a cutting configuration which lifts or chips and not in a trailing configuration unlike wire brushes where the cutting action is obtained by dragging the wire across the surface to be cleaned.
