Abstract

The covers 10 and 12 are illustrated as partial sections with only the joined or parting-line region being shown. Cover 10 is provided with a rib 14 extending parallel to the edge of cover 10. Extending from the back side of cover 10 and outward, away from the edge of cover 10, are tabs 16. Tabs 16 and their relationship to cover 10 may be more clearly seen in Fig. 2. The edge of cover 12 includes a ledge member of reduced thickness 18 and T-shaped tabs 20 extending from the ledge 18. The assembly of the two cover portions is accomplished by inserting tabs 20 between adjacent tabs 16 and corresponding in location with gaps 22 in rib 14.

Cover Latch System

The covers 10 and 12 are illustrated as partial sections with only the joined or parting-line region being shown. Cover 10 is provided with a rib 14 extending parallel to the edge of cover 10. Extending from the back side of cover 10 and outward, away from the edge of cover 10, are tabs 16. Tabs 16 and their relationship to cover 10 may be more clearly seen in Fig. 2. The edge of cover 12 includes a ledge member of reduced thickness 18 and T-shaped tabs 20 extending from the ledge 18. The assembly of the two cover portions is accomplished by inserting tabs 20 between adjacent tabs 16 and corresponding in location with gaps 22 in rib 14. Inasmuch as tabs 20 are relatively rigid, it is necessary to insert cover 12 at a slight angle with respect to cover 10, insuring that the T portion of tab 20 extends beyond rib 14, and then to rotate cover 12 downward with respect to cover 10, thereby raising the tab 20 into engagement with the rear of rib 14. If an impact occurs at the joint or parting line of the covers, the normal reaction would be for cover 12 to be forced downward with respect to cover 10, as illustrated in Fig. 2. As this is done, tabs 16 act to restrain the downward movement of cover 12 and thus prevents the disengagement of tab 20 from rib 14. The removal of cover 12 is accomplished by the partial rotation of the cover 12 in a clockwise direction with respect to cover 10, as shown in Fig. 2. Once the two cover segments are attached, rem...
