Apparatus, method, and systems for securing an accessory to a vacuum appliance

Abstract:

Described are methods, apparatuses, and systems for securing a vacuum appliance to a vacuum device including a first locking adapter that includes a tab and a second locking adapter that includes a receiving slot. The first and second adapters form an airtight seal when the tab is received by the slot by rotating one adapter relative to the other. The receiving slot can include a slot terminus to restrict rotational movement of the first adapter relative to the second. The apparatus can further include a securing slot that can secure the tab within a slot terminus such that a portion of the second locking adapter adjacent to the receiving slot is adapted to flex. Through the described rotation, the first and second adapters tighten and become rigid thus minimizing both the slippage between these two elements and the leakage between the vacuum device and any attached appliances.
