Abstract
A nozzle assembly for a power tool that generates dust includes a housing surrounding a portion of the power tool, an outlet section of the housing for accommodating the flow of dust away from the power tool and a conduit that is coupled with the outlet section to direct the flow of dust from the housing. During operation of the power tool, the conduit is rigidly coupled with the outlet section in an advanced position in which rotational movement of the conduit relative to the outlet section is impeded. The direction of dust flow out of the conduit may be selectively adjusted by transferring the assembly to a retracted position in which rotational movement of the conduit relative to the outlet section is substantially unimpeded. The outlet section and conduit may be tapered so that the advanced position is obtained through a friction fit. A preferred embodiment of the present invention further includes an arcuate channel disposed along the circumference of the conduit, a tab protruding from the housing and disposed within the channel to couple the conduit with the outlet section, a detent intermediate the channel and the inlet end of the conduit and a flexible collar intermediate the housing and the conduit. The nozzle assembly may also include a dust collection container coupled with the conduit.
