CA164029S - Ventilation duct insert - Google Patents

Abstract

The Industrial Design consists of the features of shape, pattern, ornament and configuration of the ventilation duct insert shown in the drawings. The drawings show two variants of a design which do not differ substantially from each other. Figures 1 to 11 show the first variant. Figures 12 to 22 show the second variant.Drawing(s)/photograph(s) of the design is (are) included.Fig. 1 is a front perspective view of a first variant of the ventilation duct insert with the flaps closed illustrating the present design;Fig. 2 is a top view of the ventilation duct insert with the flaps closed as shown in Fig. 1;Fig. 3 is a bottom view of the ventilation duct insert with the flaps closed as shown in Fig. 1;Fig. 4 is left side view of the ventilation duct insert as shown in Fig. 1;Fig. 5 is a right side view of the ventilation duct insert as shown in Fig. 1;Fig. 6 is front side view of the ventilation duct insert as shown in Fig. 1;Fig. 7 is a rear side view of the ventilation duct insert as shown in Fig. 1;Fig. 8 is a cross-sectional view through line 8-8 of the ventilation duct insert as shown in Fig. 2;Fig. 9 is a cross-sectional view through line 9-9 of the ventilation duct insert as shown in Fig. 2;Fig. 10 is a front perspective view of the ventilation duct insert with one flap open as shown in Fig. 1;Fig. 11 is a front perspective view of the ventilation duct insert with all flaps open as shown in Fig. 1;Fig. 12 is a perspective view of a second variant of the ventilation duct insert with flaps closed;Fig. 13 is a top view of the ventilation duct insert with the flaps closed as shown in Fig. 12;Fig. 14 is a bottom view of the ventilation duct insert with the flaps closed as shown in Fig. 12;Fig. 15 is a left side view of the ventilation duct insert as shown in Fig. 12;Fig. 16 is a right side view of the ventilation duct insert as shown in Fig. 12;Fig. 17 is a front side view of the ventilation duct insert as shown in Fig. 12;Fig. 18 is a rear side view of the ventilation duct insert as shown in Fig. 12;Fig. 19 is a cross-sectional view through line 19-19 of the ventilation duct insert as shown in Fig. 13;Fig. 20 is a cross-sectional view through line 20-20 of the ventilation duct insert as shown in Fig. 13;Fig. 21 is a front perspective view of the ventilation duct insert with one flap open as shown in Fig. 12; andFig. 22 is a front perspective view of the ventilation duct insert with all flaps open as shown in Fig. 12.
