Machine Cover

Molded panels are snap-fitted together to form a machine cover having no visible fasteners, as shown in Fig. 1.

Latches are integrally molded on the inside surfaces of the panels forming the machine. In Fig. 2, a control panel is snapped into a top panel opening and retained by lips on two integral springy tabs. Similarly, the accessory tabs of Fig. 3 are snapped into side panel holes. The long accessory dimension should be thicker than the short dimension to keep the accessory from bowing when sprung in place.

Latching is accomplished in Fig. 4 by engaging a pin, molded on the auxiliary front, with a hole in the auxiliary top. Inclined pin surfaces aid piloting of the pin into the hole when the auxiliary front is closed.

Another cover retaining technique appears in Fig. 5, where a rigid tab's lip is slid upward to lock against the sheet metal backup contacting the top. The rigid tab in Fig. 6 permits the top to pivot about a point on the front.

A louvered opening in the auxiliary front is used in Fig. 7 to removably snap a flexible tab on the auxiliary front, into a hole in a frame attached to the base. The auxiliary front can be released by inserting a screwdriver into a louver.
