Abstract
Abstract The electrically foldable door mirror comprises a base (1), a shaft (6) erected on said base, a mirror body (5) rotatably attached to said shaft, electric driving means (10) supported by a frame (8) within said mirror body for turning said mirror body, and a pinion (18) secured to the output shaft (17) of said electric driving means. The pinion is engaged with a clutch gear (20) attached to a first portion of said shaft. For a universal folding performance, the electric driving means can be automatically stopped in a predetermined position, said stopping means being disposed between one surface of a fixed clutch (21) fixed to a first end of said shaft (6) and a surface of said mirror body (5) opposing said one surface of the fixed clutch, said stopping means comprising a printed circuit (43) and contact pieces (46) slidable thereon.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
136 words
Electrically foldable door mirror comprising a base (1), a shaft (6) erected on said base, a mirror body (5) rotatably attached to said shaft, electric driving means (10) supported by a frame (8) within said mirror body for turning said mirror body, and a pinion (18) secured to the output shaft (17) of said electric driving means, said pinion being engaged with a clutch gear (20) attached to a first portion of said shaft, charcterized by means for automatically stopping said electric driving means, said stopping means being disposed between one surface of a fixed clutch (21) fixed to a first end of said shaft (6) and a surface of said mirror body (5) opposing said one surface of the fixed clutch, said stopping means comprising a printed circuit (43) and contact pieces (46) slidable thereon.
Claim 2
Dependent Claim
136 words
Electrically foldable door mirror comprising a base (1), a shaft (6) erected on said base, a mirror body (5) rotatably attached to said shaft, electric driving means (10) supported by a frame (8) within said mirror body for turning said mirror body, and a pinion (18) secured to the output shaft (17) of said electric driving means, said pinion being engaged with a clutch gear (20) attached to a first portion of said shaft, charcterized by means for automatically stopping said electric driving means, said stopping means being disposed between one surface of a fixed clutch (21) fixed to a first end of said shaft (6) and a surface of said mirror body (5) opposing said one surface of the fixed clutch, said stopping means comprising a printed circuit (43) and contact pieces (46) slidable thereon.
Claim 3
Dependent Claim
45 words
Electrically foldable door mirror as claimed in claim 1, characterized in that said mirror body (5) has a recess (50) in a position opposing said first end of said shaft (6), and a holder (40) of the contact pieces (46) is engaged with said recess.
Claim 4
Dependent Claim
56 words
Electrically foldable door mirror as claimed in claim 2, characterized in that said holder (40) holds four contact pieces (46) consisting of a pair of contact pieces for detecting the erected position of said mirror body (5) and another pair of contact pieces for detecting the position of the rear turning limit of said mirror body.
Claim 5
Dependent Claim
93 words
Electrically foldable door mirror as claimed in any of claims 1 to 3, characterized in that said printed circuit (43) has two arc-shaped conductive plates (41, 42) having different radii, one being disposed on the inside of the other, all of said contact pieces (46) being in contact with said printed circuit when said mirror body (5) is in a movable range, one of said two pairs of contact pieces being disconnected from said printed circuit when said mirror body is in the erected position or in the position of the turning limit.
Claim 6
Dependent Claim
119 words
Electrically foldable door mirror according to any of claims 1 to 4, charcterized in that an upper clutch (26a) is disposed between one surface of said clutch gear (20) and a first end of said shaft (6), a lower clutch (26b) is disposed between a surface of said frame (8) at the position of insertion of said shaft and the opposing surface of said base (1), and at least one spring (24) acts generally parallel to the axis of said shaft so as to give a force of engagement to both of said clutches, said upper clutch being more strongly engaged than said lower clutch so that said second clutch is disengaged earlier when said mirror body is turned.
Claim 7
Dependent Claim
88 words
Electrically foldable door mirror as claimed in claim 5, characterized in that the clutch gear (20) is attached to the upper portion of the shaft (6), the upper clutch (26a) is disposed between the upper surface of the clutch gear (20) and the upper end of the shaft, and the lower clutch (26b) is disposed between the lower surface of the frame (8) and the opposing surface of the base (1), and that the at least one spring is a coiled spring (24) provided around the shaft (6).
Claim 8
Dependent Claim
53 words
Electrically foldable door mirror as claimed in claim 5 or 6, charcterized in that each of said upper or lower clutches (26a, 26b) comprises a plurality of balls (28) being fitted in holes (27, 29), and is adapted to make click action so that said mirror body (5) can be turned by hand.
Claim 9
Dependent Claim
43 words
Electrically foldable door mirror as claimed in any of claims 5 to 7, characterized in that said first clutch (26a) is adapted to be disengaged when the load becomes larger, so that a mechanism (15, 16) driving said pinion (18) is not overloaded.
