Abstract

An easily fabricated, substantially vibration-free inside mirror assembly permitting the user to positively and easily change selectively the two reflecting positions thereof is obtained by the arrangement: a mirror having two intersecting front and rear reflection surfaces with low and high reflection factors, respectively, and being secured to the open front side of a mirror casing molded with a synthetic resin, and a mirror angle regulating polygonal plate fixed around a mirror angle shifting rod and extending through the bottom wall of said casing and engagingly inserted, at its top, in the bottom slot of an attachment fitting pivotably supported in the mirror casing, said plate being resiliently nipped by a pair of stoppers formed in the mirror casing integrally therewith.

Claims

1. An adjustable rear view mirror assembly for vehicles comprising in combination;

a casing formed from synthetic resin material and having an open front side, a mirror mounted in said open front side of said casing, said mirror having a first face having a high reflection factor and a second face having a low reflection factor, the planes of said faces intersecting each other at a predetermined angle, said casing having back and bottom wall portions said backwall portion having a generally centrally disposed aperture for receiving an articulated spherical member of a mounting bracket, said casing having an attachment fitting pivotally mounted therein adjacent said top wall for engaging said spherical member of said mounting bracket, said backwall of said casing having, approximate said bottom wall, at least one pair of generally horizontally disposed holding arms formed integrally with said backwall and spaced vertically from each other, said bottom wall having an aperture through which extends a reflection factor shifting rod, said rod being rotatably supported by said holding arms and provided at its end remote from said aperture with an eccentrically positioned lug, said other end of said shifting rod being disposed exteriorly of said casing, said attachment fitting having a bottom wall formed with an oblong slot for receiving said lug so that rotation of said rod will effect an angular displacement of said mirror casing about a generally horizontal axis with respect to said attachment fitting, the improvement comprising;

said backwall of said casing having integrally formed therewith a pair of horizontally extending, resilient stopper arms having opposed faces extending in generally parallel, vertical planes, said stopper arms being disposed on opposite sides of said shifting rod, said rod having a mirror position regulating plate of polygonal cross section formed thereon with a plurality of pairs of parallel faces, said faces of each pair being on opposite sides of said plate so that said faces of said stopper arm will engage parallel pairs of faces of said plate to releasably restrain rotation of said rod.

2. An inside mirror assembly according to claim 1, wherein said attachment fitting is provided, substantially centrally of the vertical rear wall thereof, with an opening for insertion of the stem of an articulate spherical member and a seat formed around said opening for receiving said spherical member, said spherical member being nipped between a leaf spring fixed to said attachment fitting and said seat formed in said attachment fitting, the rear end portion of the stem of said articulate spherical member extending rearwardly through an aperture formed in the vertical rear wall of said mirror casing and being attached at its end, to a mounting bracket.

3. An inside mirror assembly according to claim 2, wherein said leaf spring has spaced lugs extending from the lowermost end edge thereof, said attachment fitting being provided with recesses in the body thereof for insertion of said lugs, said lugs of said leaf spring being inserted in said recessed, said leaf spring being fastened, at an upper site thereof, to said attachment fitting by a screw.

4. An inside mirror assembly according to claim 1, wherein said mirror is fitted in recessed grooves formed inside and along the peripheral edges of said open front of said mirror casing.

5. An inside mirror assembly according to claim 1, wherein said attachment fitting is provided, substantially centrally of the vertical rear wall thereof, with an opening for the insertion of the stem of an articulate spherical member therethrough and also provided, around and adjacent to said opening, with a seat for receiving said spherical member, said mirror position regulating plate being square in shape and being provided around the upper portion of said shifting rod, said stem of said articulate spherical member extending rearwardly through said opening of said attachment fitting, there being fixed a leaf spring to the attachment fitting to nip said spherical member between said leaf spring and said seat, there being attached, to the lowermost end of said shifting rod, a lever extending rearwardly and in perpendicular relation to said shifting rod, the free end of said stem of said articulate spherical member being coupled to one end of a mounting bracket which is fixed, at the other end, to the inside wall of the chamber in said vehicle.

6. An inside mirror assembly according to claim 1, wherein said attachment fitting is provided, substantially centrally of the vertical rear wall thereof, with an opening for the insertion of the stem of an articulate spherical member therethrough and also provided, around and adjacent to said opening, with a seat for receiving said spherical member, said mirror position regulating plate being square in shape and being provided around the upper portion of said shifting rod, said stem of said articulate spherical member extending rearwardly through said opening of said attachment fitting, there being fixed a leaf spring to the attachment fitting to nip said spherical member between said leaf spring and said seat, there being attached, to the lowermost end of said shifting rod, a lever extending rearwardly and in perpendicular relation to said shifting rod, the free end of said stem of said articulate spherical member being coupled to one end of a stay which has, at the other end, its base portion having a tapered surface, the flat end face of said base portion being applied to the flat top face of a disc-shaped platform member having its rear face securely attached to the inside face of the front glass pane of said vehicle, said disc-shaped platform member having a thread formed around its lateral periphery, said platform member and said base portion of said stay being mounted by a cap having a threaded inner wall portion and an adjacent tapered inner wall portion the inclination of the tapered wall of said cap being complementary to that of the tapered surface of said base portion of the stay, said cap being screwed onto said platform member whereby said base portion having the tapered surface is tightly fastened to said platform by the engagement of said tapered surface of said base portion and said tapered inner face of said cap.
