International Classification:

B24B 2300

US Classification:

451344, 451354, 451495

Abstract:

A variable camber sanding board includes a generally planar and flexible sanding base, which is adapted to receive abrasive sheet material. A front frame is pivotably linked to a mid handle via a front pivot connection. The front pivot connection includes a pin passing through coaxial bores formed in the mid handle and front frame. A mid handle includes a slotted attachment member which is pivotably secured to a trigger link, forming a middle pivot connection. The trigger link is pivotably secured to a rear handle which is secured to the sanding base via a rear frame. An adjustment pivot connection includes a pin passing through coaxial bores formed in the slot link and rear frame, respectively. A threaded knob assembly, which passes through a bore located in the trigger link and a slot in the slot link can be selectively tightened in a desired position along the length of the slot link.

Abstract:

An apparatus for supporting an abrasive material includes a flexible base defined by a first end and a second end, and by a lower surface which supports the abrasive material and an upper surface opposite the lower surface. The flexible base is fabricated from a resilient material so as to assume an essentially flat shape when the ends of the flexible base are not acted on by external forces. A front frame is member attached to the flexible base proximate the first end, and a rear frame member is attached to the flexible base proximate the second end. An adjustable connecting link has a first end connected to the front frame member in fixed relation thereto. A second end of the adjustable connecting link is connected to the rear frame member by a variably positionable connection.
