Abstract
An adjustable trowel to facilitate formation of a coved corner between two structural panels comprises a blade having two laterally spaced trapezoidal-shaped, rigid wing segments integrally joined along parallel inside edges by an intermediate segment which is of rectangular shape and of reduced thickness compared to the rigid wing segments to allow flexure in the zone occupied by the intermediate segment. Affixed to each of the rigid wing segments are handle mounting brackets that overlap one another and include an arcuate slot therein for receiving a handle mounting bolt therethrough. By tightening the bolt, the wings are held at a selected angle to one another and with the intermediate segment assuming a desired curvature.
Claims10
An adjustable trowel for creating a coved corner between abutting wall board panels, comprising:
- (a) a relatively flexible sheet of material having a memory property tending to maintain said sheet in a planar configuration;
- (b) first and second relatively rigid plates having inner and outer side edges, said plates being affixed to the flexible sheet with a predetermined spacing between said inner side edges of the first and second plates;
- (c) handle mounting brackets fastened to said first and second relatively rigid plates and extending perpendicularly therefrom;
- (d) a handle;
- and
- (e) means for securing the handle to the handle-mounting brackets such that the first and second relatively rigid plates are held in a non-coplanar relationship and said flexible sheet is arcuately bent in the predetermined spacing.
An adjustable trowel for creating a coved corner between abutting construction panels, comprising:
- a) a generally rigid sheet of material of a predetermined thickness over a majority of its surface but having a rectangular central zone of a predetermined width dimension, the rectangular central zone being of a constant lesser thickness dimension than the predetermined thickness;
- (b) handle brackets affixed to the generally rigid sheet and extending perpendicuiarly to the sheet to span the central zone;
- (c) a handle;
- and
- (d) means for attaching the handle to the brackets to clamp the brackets with a predetermined arc imparted to the sheet in the central zone.
