Abstract
Proposed is a furniture front element like a cabinet door, of which the frame leg members are joined in mitre cut and without any screwed connection. The lengths of the leg members are infinitely adjustable and the frame filling pieces are designed as a storage means in order to be able to change the front surface of the element to the desired extent.
Claims2
A method for manufacturing a front element for furniture or the like which includes a four sided perimeter frame and a filling panel received within the frame, said method comprising the steps of;
- (a) cutting elongated frame pieces of wood or plastic to selected profile and length and having mitered corners, and sealing the surfaces cut,
- (b) providing a filling piece receiving groove extending longitudinally along one face of each piece,
- (c) forming at least one short hole extending in a longitudinal direction in each end of each frame piece extending from the mitered face,
- (d) forming at least one additional bore hole of a diameter greater than the first mentioned bore hole adjacent each end of each frame piece extending from and normal to the rear face thereof and terminating within the piece and intersecting the first mentioned bore hole at a distance spaced longitudinally from said mitered face thereof,
- (e) inserting a rotatable eccentric fitting within each of said additional bore holes,
- (f) interconnecting three of said frame pieces by means of right angle dowel pieces inserted in adjoining holes in said mitered faces, each dowel piece having a reduced neck spaced inwardly from its end,
- (g) rotating said eccentric fittings into the reduced necks of said dowels of the three frame pieces to draw the same tightly together,
- (h) inserting at least one generally planar filling piece within the groove defined by the three interlocked frame pieces,
- (i) joining the fourth frame piece to the partially assembled frame about the exposed edge of said filling piece by insertion of the right angle dowels associated therewith into the first mentioned holes in the adjacent frame pieces, and
- (j) rotating the remaining eccentric fittings to tighten the assembly about the filling piece.
