WO2009047642A3 - On-base luminaires made of a precut semi rigid and ready to mount material - Google Patents

Abstract

The device of the invention is designed to solve said drawbacks. According to a first feature, it comprises using a single semi-rigid material for all the members constituting said luminaires. They may consist of two or three parts such as the shade, the base and independent plates. The planar disk-shaped shade (A) has folding lines (p1) extending across the same (Fig. 1a) when folding the different members upwards on each side of them, a flower-shaped shade can be obtained (Fig. 2a). The locking ring (N) is then installed while inserting the fasteners located above the shade on the outline (V1) thereof into the slots (F1) (Fig. 2b). The sides of the fasteners (v1, v2) are then folded towards the centre using the fold lines (p) (Fig. 4b) and inserted into the slot (F1) (Fig. 4d). Once inside, the fastener sides are unfolded and the assembly is locked (Fig. 4e). Once the locking ring is in position (Fig. 3c), the shade is turned upside down and the lamp dowel (DL) is placed inside the hole (T) located at the centre of the incorporated plate (P1) of the base and the shade (Fig. 3b). Once in position (Fig. 6), the shade is folded flat (Fig. 5a) using the fold lines (p4) between the various members, and is closed by placing the fasteners (V5) and (V5') inside the slots (F4) and (F4'). After these two steps, a base with a square bottom and walls inclined at 45° can be obtained (Fig. 5c). Before attaching the base to the shade, the fastener (V5') is disengaged from the slot (F4'), the wire of the dowel (FL) is inserted from the inside to the outside through the cut (k) for inserting the same into the opening (O) provided therefore, and the fastener (V5') is again inserted into the slot (F4') (Fig. 6a).
