  • Rotatable indexable accessory vacuum cleaner tool
    Patent number: 4951348
    Abstract: An accessory crevice tool for a hand vacuum cleaner includes a stationary portion having an adapter fittable into an inlet opening in the dust bowl of the hand-held vacuum cleaner and a rotatable portion fitted thereon. Detents in the connection between the stationary portion and the rotatable portion of the crevice tool permit stable retention of the crevice tool in a desired rotational position. A spring clip can be positioned in the inlet opening for engagement with a surface of the adapter. A locking portion of the spring clip can extend into the inlet opening for engagement with an optional latching groove in the surface of the adapter. This engagement retains the crevice tool attached to the dust bowl against all but affirmative effort to disengage them.
