ABSTRACT:
A video tape cassette reel having an economically and simply made pivot button member formed independently of the discs and the hub making up the tape reel. The pivot button member is made of a material which resists abrasion, e.g., polyacetal, whereas the hub portion and the flat discs or reels are made of a less expensive plastic. In one embodiment, the pivot button member has a base with a pivot button thereon and three substantially flat legs extending radially from the base. The legs are inserted through a central opening in the upper reel disc and the pivot button member is twisted about 60 degrees so that the legs are lodged under the upper disc and the pivot button member becomes secured in place. In another embodiment, the pivot button member has a substantially flat base with a pivot button thereon. This button member locks the hub and the upper and lower reel discs together by providing three lipped-posts on the hub, placing the lipped-posts through three corresponding openings in the upper disc so that the upper disc rests on the hub, and finally, placing the pivot button member between the posts and twisting the button member, such that the upper surface of the pivot button member base is secured below the lips of the posts and the bottom surface of the pivot button then rests on the upper disc.
