Abrasive holder
View Patent ↗An abrasive tool comprising of a base portion ( 2 ), having a foam layer ( 3 ) affixed to the abrasive tool base portion, and a plastic film layer ( 4 ) affixed, bonded or glued to the foam layer. This tool is adapted to receive an abrasive material layer ( 5 ) or sand paper or other abrasive material having a pressure sensitive adhesive applied to one side of the abrasive material, to allow said abrasive material to be stuck and affixed to the abrasive tool. The abrasive tool may be hand operated, or operated by electric power, air power, or other motive power.
1. An abrasive tool comprising:
a handle portion having an arcuate configuration;
a flexible base portion removably attachable to said handle portion about a central pivot line by a connection configuration selected from the group consisting of a tongue-in-groove configuration, and a key in slot configuration;
a foam layer attachable to said flexible base portion;
a plastic film layer attachable to said foam layer;
at least two screw members each of which attachable to an end said handle portion and to a corresponding end of said flexible base portion for adjustably fixing the curvature of said flexible base portion, said screw members pass through their respective ends of said handle portion;
at least two sockets each of which pivotably connected to an end of said flexible base portion, each of said sockets being adapted to receive said screw members and pivotably connect said screw members to their respective ends of said flexible base portion; and
a rod fixed within each end of said flexible base portion substantially across the entire width of said flexible base portion;
wherein each said socket is pivotable about one of said rods that is fixed within a corresponding end of said flexible portion.
2. The abrasive tool as set forth in claim 1 further comprising an abrasive material layer attachable to said plastic film layer.
3. The abrasive tool as set forth in claim 2 , wherein said abrasive layer comprises abrasive material fixed to a backing layer, said backing layer being attachable to said plastic film layer.
4. The abrasive tool as set forth in claim 3 , wherein said backing layer of said abrasive layer is provided with an adhesive to removably attach said backing layer to said plastic film layer.
5. The abrasive tool as set forth in claim 4 , wherein said adhesive is a pressure sensitive adhesive.
6. The abrasive tool as set forth in claim 2 , wherein said foam layer is selected from the group consisting of ethyl vinyl acetate foam, polyethylene foam, and polypropylene.
7. The abrasive tool as set forth in claim 2 , wherein said plastic film layer is selected from the group consisting of ethyl vinyl acetate film, polyethylene film, and polypropylene.
8. The abrasive tool as set forth in claim 2 , wherein said flexible base portion is removably attached to said handle portion by a tongue-in-groove configuration located on said central pivot line.
9. The abrasive tool as set forth in claim 2 , wherein said flexible base portion is removably attached to said handle portion by a key in slot configuration located on said central pivot line.
10. An abrasive tool comprising:
a handle portion having an arcuate configuration;
a flexible base portion removably attachable to said handle portion about a central pivot line by a connection configuration selected from the group consisting of a tongue-in-groove configuration, and a key in slot configuration;
a foam layer attachable to said flexible base portion;
a plastic film layer attachable to said foam layer;
an abrasive material layer having an abrasive material fixed to a backing layer, said backing layer having a pressure sensitive adhesive provided thereon, said backing layer being removably attachable to said plastic film layer;
at least two screw members each of which attachable to an end said handle portion and to a corresponding end of said flexible base portion for adjustably fixing the curvature of said flexible base portion, said screw members pass through their respective ends of said handle portion;
at least two sockets each of which pivotably connected to an end of said flexible base portion, each of said sockets being adapted to receive said screw members and pivotably connect said screw members to their respective ends of said flexible base portion; and
a rod fixed within each end of said flexible base portion substantially across the entire width of said flexible base portion;
wherein each said socket is pivotable about one of said rods that is fixed within a corresponding end said flexible base portion.
11. The abrasive tool as set forth in claim 10 , wherein said foam layer is selected from the group consisting of ethyl vinyl acetate foam, polyethylene foam, and polypropylene.
12. The abrasive tool as set forth in claim 10 , wherein said plastic film layer is selected from the group consisting of ethyl vinyl acetate film, polyethylene film, and polypropylene.
