发明名称 Snap-in swivel end fitting
摘要 A flexible vacuum cleaner hose is provided with a simple and inexpensive end fitting for use with various vacuum cleaner accessories and attachments. The hose is a corrugated plastic, i.e., it has annular rings or corrugations formed therein. Each section of hose has a predetermined length with a suitable cuff on each end thereof. Each of the cuffs includes a snap lock. The end fitting is a one piece molded member having a locking seat and a tapered end section or a threaded end section. The tapered section is adapted to be forced into the cuff so as to spread the snap lock on the cuff. The snap lock rides over the end section and drops into the locking seat formed therebehind. This is effective to lock the end fitting on the hose while allowing it to remain free to rotate inside the cuff.
