ROTARY SEGMENTED FLOOR STRIPPING PAD

Abstract

The present disclosure provides a segmented rotary floor stripping pad having a plurality of symmetrical, polygonal pad segments secured together in partially overlapping relation to form an annular pad. The segments are preferably formed from non-woven polyester fibers and are secured radially along the overlapping, adjacent side edges by hot melt glue, ultrasonic welding or by stitching. There is no backing pad, and since the segments are symmetrical, the pad is reversible so that both sides can be used. The plurality of pad segments are secured together in an overlapping manner such that each pad segment presents an angled leading cutting edge and each pair of adjacent pad segments forms a radial fluid channel. Depending on the degree of overlap and the thickness of the pad segment, the presentation angle of the cutting edge can be varied.

DETAILED DESCRIPTION OF THE INVENTION

[0013] Referring now to the drawings, an exemplary embodiment of the present floor stripping pad is generally indicated at 10 in FIGS. 1-6. As will be explained further herein, the floor stripping pad 10 is used in conjunction with a rotary floor cleaning machine (not shown) which is well known in the art. The exemplary pad 10 is placed beneath the machine and is held in place by friction. In other exemplary embodiments, the pad can be held in place by the use of a center screw on the rotary floor machine which keeps the pad concentric. In use, the pad 10 rotates beneath the machine in a counterclockwise direction.

[0014] The exemplary embodiment illustrates a segmented rotary floor stripping pad 10 comprising a plurality of symmetrical, polygonal pad segments 12 that are secured together in partially overlapping relation to form an annular shaped pad generally of the same size and configuration as a conventional circular or annular floor pad.

[0015] The pad segments 12 are preferably formed from an open-textured, non-woven polymer fiber material such as polyamide, polyester or nylon fiber material. Other polymer fiber materials, are also contemplated. In some embodiments, the non-woven fiber material may also include natural fibers, such as walnut fibers or coconut fibers. In still other embodiments, the non-woven material may include mineral or resin abrasive particles which are uniformly distributed throughout, and securely bonded to the non-woven fiber material with a phenolic or latex resin coating. The non-woven fibrous nature of the material is best seen in FIG. 6.

[0016] The prior art pads are stamped out of a pre-formed planar sheet of such a material. However, the stamping process leaves a substantial amount of edge waste which must be recycled or discarded. The present pad segments 12 are symmetrical wedges which can be stamped, for example, from the same sheet of material with very little waste.

[0017] As seen in FIG. 4, each pad segment 12 is polygonal in shape having an inner arcuate circumferential edge 14, an outer arcuate circumferential edge 16 and opposing side edges 18, 20. The arcuate pad segment 12 preferably measures about 20 of arc. However, other embodiments may have larger or smaller dimensions.

[0018] Turning back to FIG. 1, it can be seen that twenty-four (24) pad segments 12 are secured radially along their overlapping, adjacent side edges to form the annular shape of the pad. In the exemplary embodiment, the pad segments are preferably secured by radially extending beads of hot melt glue 22 which extend along substantially the entire length of the side edges (dotted line in FIG. 3). In other embodiments, the segments may be ultrasonically welded or stitched along the same edges. It is important to note that there is no backing pad, and since the segments 12 are symmetrical, the pad 12 is reversible so that both sides can be used. The plan view of the top surface shown in FIG. 3 is identical to a plan view of the bottom surface (not shown).

[0019] Turing back to FIGS. 1 and 2, the plurality of pad segments 12 are secured together in an overlapping manner such that each pad segment 12 presents an angled leading cutting edge 24 and each pair of adjacent pad segments forms a radial fluid channel 26. Depending on the degree of overlap, the width of the pad segment 12 and the thickness of the pad segment 12, the presentation angle of the leading edge 24 can be varied.

[0020] In use, as the pad rotates (See arrows A in FIG. 3), the leading cutting edges 24 bite into the wax and aggressively strip wax from the floor. The rotary motion of the pad 12 also centrifugally pushes stripping fluid and excess wax material radially outward (See arrows B) along the fluid channels 26 to keep the underside of the pad clean and free of wax build up.

[0021] Some embodiments may comprise varying numbers of pad segments. Preferably, each pad comprises 24 symmetrically identical segments. The dimension, shape and configuration of the segments may be modified to suit the application at hand.

[0022] Other embodiments may include toothed leading edges or scalloped edges. Still further embodiments may include non-linear leading edges for different stripping action.

[0023] It can therefore be seen that the exemplary embodiments provide a novel and inventive floor stripping pad, which more quickly strips wax buildup from floors and has a longer useful life.

[0024] While there is shown and described herein certain specific structures embodying various embodiments of the invention, it will be manifest to those skilled in the art that various modifications and rearrangements of the parts may be made without departing from the spirit and scope of the underlying inventive concept and that the same is not limited to the particular forms herein shown and described except insofar as indicated by the scope of the appended claims.
