Patent ID: 7585081

Claim:
An extendable rearview mirror device for vehicles having handlebars, the device comprising: an elongated rigid mirror mounting shaft comprising a proximal end attaching portion comprising a substantially vertical rigid attaching shaft having a means for connecting the mirror mounting shaft to a mirror receiving mount on a handlebar and bodywork of a vehicle, and a longer straight mirror receiving shaft at a distal end contiguous with the rigid attaching shaft and angled upwardly therefrom for receiving a rearview mirror slidably attached thereon so that the mirror is adjustably positioned at any desired location along the length of the mirror mounting shaft; a rearview mirror assembly comprising a reflective surface in a mirror frame to enable a driver of the vehicle to see behind the vehicle and a mirror mount assembly comprising an external housing; a ball and socket mount modified to allow the mirror receiving shaft to pass through the ball and socket mount while still allowing pivotal adjustment of the reflective surface; a collet slidably mounted on the mirror receiving shaft, the collet comprising means for engaging the ball and socket mount to allow rotation of the ball and socket mount to adjust the reflective surface, a distal hollow cylindrical portion with a first threaded portion at a distal end, and a stepped portion having a larger diameter than the cylindrical portion, the stepped portion having a larger diameter second threaded portion adjacent to the cylindrical portion and a split truncated conical portion tapering from the larger diameter second threaded portion to a proximal end; a knurled locking collar slidably mounted on the mirror receiving shaft adjacent to the split truncated conical portion of the collet, the knurled locking collar comprising a truncated conical external surface bearing surface knurls for gripping by hand and an internal distal threaded portion to mate with the second threaded portion of the collet and an internal tapered truncated conical surface to engage the split truncated conical surface of the collet so that threading the knurled locking collar onto the collet binds the collet against the mirror receiving shaft to lock the rearview mirror assembly at a desired point along the mirror receiving shaft thereby forming an extendable rearview mirror device for vehicles having handlebars.
