  • Patent number: 5937476
    Abstract: A vacuum cleaner with a cord-reel release apparatus provides a handle in place of a cord reel button. The cord-reel release apparatus has a cord reel, a brake member, an elastic member, and a handle. The cord reel winds a power cord. The brake member is in contact with circumference of the cord reel and selectively limits rotation of the cord reel. The elastic member causes one part of the brake member to contact with the cord reel. The handle presses the other part of the brake member. The handle further has a hooking prominence formed on a side part thereof, thereby the hooking prominence is hooked to a hooking depression formed in an accommodation groove of a body. With the constitution, when the brake member is pressed by the handle, the brake member departs from the cord reel. Then, the power cord drawn out is wound up at the cord reel by elastic force of a spiral spring in the cord reel. By the cord-reel release apparatus, a simple constitution, low cost, and high productivity are accomplished.
