Remote control rear view mirror operating mechanism
First Claim
1. An electrical drive and switching arrangement for reversible electric motors operative of rear view mirrors for vehicles and providing for remote control actuation thereof, said arrangement including a housing structure for a small reversible electric motor, a threaded shaft driven by the motor and having a travel nut thereon, a mirror member and a mirror drive connection with follower operatively engaged with the travel nut, all of which provides an operating mechanism for a remote control rear view mirror, said housing structure comprising a complimentary housing member parts of relatively thin walled construction and like contour in cross-section for receiving said motor and shaft longitudinally therebetween and having them closely fitted therewithin, said housing member parts having their opposite and respective ends curved and contoured to also more closely encase the ends of said motor shaft and to provide structural strength in combination and to the exclusion of non-functional internal walls and ribs, a motor mounting wall member respective within and between said housing parts and having the reversible electric motor pre-assembled thereto and extended on one side thereof and with the threaded shaft driven by the motor extended therethrough and on the other side thereof, receptive means formed within said housing member parts and grooved to receive and retain said mounting wall member in precise location therebetween and in cross-sectional strengthening relation transversely across said housing member parts as received and entrapped therewithin, parallel spaced guide walls provided longitudinally within one of said housing member parts from said mounting wall receptive means towards the end of said one housing part for retaining the threaded shaft and its travel nut therebetween and providing added structural strength to said housing part, bearing receptive means provided between the ends of said guide walls and bearing means receptive in said means and of the end of said threaded shaft for supporting said threaded shaft and its travel nut relatively spaced from the bottom wall of said one housing part, means received through the other of said housing member parts and including said mirror drive connection and said follower for travel nut engagement, and means sealing housing member parts together and retaining said operating mechanism in assembly as described therebetween, electrical means received and retained between said guide walls lengthwise under the threaded shaft for operative control of said motor and for contact engagement with said travel nut to effectuate reverse drive of said motor at end travel positions upon actuation of reversible switch means, said travel nut being relieved transversely thereacross an opposite sides thereof to afford relative bending freedom longitudinally for eliminating thread play and having a downwardly tappering slot receptive of the end of said follower or like shape therewithin, and said follower supporting the weight of said mirror member and mirror drive connection to provide the close fitting of said travel nut on said threaded shaft and the contact engagement required.
