Abstract

To join two sheet metal parts together, one of the parts is provided with a tab, and the other part is provided with an opening in the form of a mating slot. Referring to Figures 1 through 4, it can be seen that part 10 is provided with a tab 12 and part 14 is provided with a mating slot 16. To join the two parts, the tab 12 is inserted into the slot 16, the tab shoulders 18 and 20 engaging the ends of the slot 16 to locate the parts. When the tab 12 is twisted, as shown in Figures 3 and 4, the tab slopes 22 and 24 engage the sides of the slot 16 to securely clamp the parts together.

TWIST TAB ASSEMBLY (Cont'd)

To join two sheet metal parts together, one of the parts is provided with a tab, and the other part is provided with an opening in the form of a mating slot. Referring to Figures 1 through 4, it can be seen that part 10 is provided with a tab 12 and part 14 is provided with a mating slot 16. To join the two parts, the tab 12 is inserted into the slot 16, the tab shoulders 18 and 20 engaging the ends of the slot 16 to locate the parts. When the tab 12 is twisted, as shown in Figures 3 and 4, the tab slopes 22 and 24 engage the sides of the slot 16 to securely clamp the parts together.

Figure 5 shows an alternative arrangement wherein the opening 16' is diamond shaped. Major axis A-A admits the flat tab, and the minor axis B-B provides a means of limiting torque and the degree of twist of the tab.
