Trank frame reinforcing device

Abstract

Abstract PURPOSE: To obtain a top wall frame for a portable case given with a considerably reinforced beam strength only in the top wall by connecting a double grooved structural material to a supporting frame the top wall on the half part of a fixed case. CONSTITUTION: A portable case 10 has the half part of the fixed case 12 and the half movable case, namely cover 14. Both of these half parts have a side wall 15, another side wall 16 and bottom wall 17. The half fixed case has a top wall 18 and the movable case has also a top wall 19. The double grooved structural material 50 has a hook 53 and a considerably vertical section ends at a pair of legs 52 which extend downward. The leg 52 can deform slightly and elastically, so the double grooved structural material can be pushed into the recess of closed frame, and snap-fitted to an adequate part and retained. The considerably vertical section gives a beam strength to the top wall of portable case. The supporting frame 22 having latch mechanisms 72 and 74 and a screw 41 mounts the latch mechanism 72 on the supporting frame 22. The latch mechanism overlaps on the end of the double grooved structural angle 50 and fixes it so as not to move.
