Abstract

A buffing pad. The buffing pad includes a pad support having a first surface and a second surface; and a resilient foam pad having an attachment surface and a buffing surface, the attachment surface of the resilient foam pad secured to the first surface of the pad support, the resilient foam pad comprising at least two separate concentric rings of resilient foam, the concentric rings being positioned so that there is a gap therebetween. A method of making the buffing pad is also disclosed.

Claims

exact text as granted — not AI-modified

1 . A buffing pad comprising:
a pad support having a first surface and a second surface; a resilient foam pad having an attachment surface and a buffing surface, the attachment surface of the resilient foam pad secured to the first surface of the pad support, the resilient foam pad comprising at least two separate concentric rings of resilient foam, the concentric rings being positioned so that there is a gap therebetween.

2 . The buffing pad of claim 1 wherein the resilient foam pad comprises at least three separate concentric rings of resilient foam.

3 . The buffing pad of claim 1 wherein the concentric rings are made of different types of resilient foam.

4 . The buffing pad of claim 1 wherein the concentric rings are made of the same type of resilient foam.

5 . The buffing pad of claim 1 wherein the resilient foam pad is permanently secured to the first surface of the pad support.

6 . The buffing pad of claim 1 wherein the second surface of the pad support has a connector selected from hooks or loops.

7 . The buffing pad of claim 1 wherein an outer edge of the buffing surface of the resilient foam pad has a radius.

8 . The buffing pad of claim 1 wherein the concentric rings have different thicknesses.

9 . The buffing pad of claim 1 wherein the concentric rings have the same thickness.

10 . The buffing pad of claim 1 wherein the concentric rings have different widths.

11 . The buffing pad of claim 1 further comprising a second resilient foam pad having an attachment surface and a buffing surface, the attachment surface of the second resilient foam pad secured to the second surface of the pad support, the second resilient foam pad comprising at least two separate concentric rings of resilient foam, the concentric rings being positioned so that there is a gap therebetween.

12 . A buffing pad comprising:
a pair of a pad supports having a first surface and a second surface;
a pair of resilient foam pads having an attachment surface and a buffing surface, the attachment surface of the pair of resilient foam pads secured to the first surface of the pair of pad supports, the pair of resilient foam pads comprising at least two separate concentric rings of resilient foam, the concentric rings being positioned so that there is a gap therebetween,
wherein the second surfaces of the pair of pad supports are secured to each other.

13 . A method of making a buffing pad comprising:
providing a pad support having a first surface and a second surface; providing at least two concentric rings of resilient foam, the concentric rings having an attachment surface and a buffing surface; positioning the concentric rings on the first surface of the pad support so that there is a gap between the concentric rings; and securing the attachment surface of the concentric rings to the first surface of the pad support.

14 . The method of claim 13 wherein the concentric rings are permanently secured to the first surface of the pad support.

15 . The method of claim 13 wherein the concentric rings are made of different types of resilient foam.

16 . The method of claim 13 further comprising attaching a connector to the second surface of the pad support, the connector selected from hooks or loops.

17 . The method of claim 13 further comprising forming a radius on an outer edge of the buffing surface of the outer concentric ring.

18 . The method of claim 13 wherein the concentric rings have different thicknesses.

19 . The method of claim 13 wherein the concentric rings have different widths.

20 . The method of claim 13 further comprising:
providing at least two second concentric rings of resilient foam, the second concentric rings having an attachment surface and a buffing surface; positioning the second concentric rings on the second surface of the pad support so that there is a gap between the concentric rings; and securing the attachment surface of the second concentric rings to the second surface of the pad support.

21 . The method of claim 13 further comprising;
providing a second buffing pad, the second buffing pad comprising:
a second pad support having a first surface and a second surface; and
a second resilient foam pad having an attachment surface and a buffing surface, the attachment surface of the second resilient foam pad secured to the first surface of the second pad support, the second resilient foam pad comprising at least two separate concentric rings of resilient foam, the concentric rings being positioned so that there is a gap therebetween; and
securing the second surface of the pad support to the second surface of the second pad support.
