Abstract
Abstract An external rear-view mirror for vehicles in which the gearing ratio of the means of rotating the body of said mirror with reference to the vehicle is so high as to make virtually impossible, turning said body manually incorporates at least one clutch into the gear train of the means of rotating said body. The clutch is adjusted to render the elements substantially united when said body is rotated mechanically, but allows the elements to reciprocally slide when said body is rotated manually.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
94 words
Device for the motorized control of the rotation of the body of an external rear-view mirror for vehicles through reduction gears, characterized by the ratio of the reduction gear being so high as to render practically impossible the manual rotation of the output shaft of the same; and by at least one clutch being incorporated into the gear train controlling the rotation of the body, said clutch being adjusted to render the elements substantially united when said body is rotated mechanically, but allowing the elements to reciprocally slide when said body is rotated manually.
Claim 2
Dependent Claim
94 words
Device for the motorized control of the rotation of the body of an external rear-view mirror for vehicles through reduction gears, characterized by the ratio of the reduction gear being so high as to render practically impossible the manual rotation of the output shaft of the same; and by at least one clutch being incorporated into the gear train controlling the rotation of the body, said clutch being adjusted to render the elements substantially united when said body is rotated mechanically, but allowing the elements to reciprocally slide when said body is rotated manually.
Claim 3
Dependent Claim
24 words
Device according to Claim 1 characterized by the said clutch being provided onto the output shaft of the reduction gears of said electric motor.
Claim 4
Dependent Claim
59 words
Device according to Claim 1 in which said gear train comprises of a pinion and crown wheel, characterized by said electric motor and reduction gears being fixed to the support base of the body of the mirror, the crown wheel being fitted to the mirror body, and said clutch being provided between the mirror body and the crown wheel.
Claim 5
Dependent Claim
57 words
Device according to Claim 1 in which said gear train consists of a pinion and crown wheel, characterized by said electric motor and reduction gears being fixed to the mirror body, and moving with it; the crown wheel being fitted to the support base, and the clutch being provided between the crown wheel and the support base.
Claim 6
Dependent Claim
24 words
Device according to Claim 4 characterized by the friction surfaces between the crown wheel and the support base being shaped as complementary cone frustums.
Claim 7
Dependent Claim
28 words
Device according to Claims 4 and 5, characterized by the crown wheel being fitted coaxially to a pivot which functions as a fulcrum housed in the support base.
Claim 8
Dependent Claim
55 words
Device according to Claim 6 characterized by the crown wheel being braced between the support base and at least one protruberance on the pivot, and by a compression spring acting between a regulating nut fitted to said pivot and the support base, forcing the crown wheel against the support base, by means of said protuberance.
Claim 9
Dependent Claim
34 words
Device according to one of the Claims 4 to 7, characterized by said mirror body bearing on said pivot through a bush with low friction coefficient which bears against a protuberance of said pivot.
Claim 10
Dependent Claim
34 words
Device according to Claim 8 characterized by a compression spring acting between a regulating nut fitted to the pivot and the extremity of said bush, to maintain said body pressed against said lateral protuberance.
Claim 11
Dependent Claim
61 words
Device according to any of the preceeding Claims characterized by having means of controlling the rotation and positioning of the body, said means comprising a plurality of niches or recesses arranged along a fixed path and switching means mobile along said path and insertable in said niches to act on an electrical circuit to control the operation of the electric motor.
Claim 12
Dependent Claim
68 words
Device according to Claim 10, characterized by the niches being arranged on said fixed support base, and said switching means consisting of an elongated body with a hemispherical extremity, moving with the mobile part, and being forced axially against said support base; said elongated body being integral with an actuating rod axially mobile with said elongated body to switch on and off a microswitch connected to said circuit.
Claim 13
Dependent Claim
25 words
Device according to Claim 11, characterized by said microswitch being connected in parallel with a two-way commutator which functions as a timer and polarity inverter.
