Abstract

A rear view mirror mounted on an interior surface of a vehicle has a base, a frame and a stay. The frame arranged on an upper surface of the stay contains an elastic engaging means including an arc-shaped leaf spring and on an inside wall surface of a cavity of the base, dents are formed for elastically receiving stoppers of respective ends of the arc-shaped leaf spring when the frame is engaged in the cavity. When an external force is applied to the stay, the stay easily drops out of the base due to removing the stopper from the dent.

Claims

1. An inside rear view mirror for a vehicle, comprising:

a base to be secured to an interior surface of a vehicle and having a bottom surface and a cavity formed in said bottom surface;

a stay detachably mounted on said bottom surface of said base and having an upper surface;

a frame arranged at said upper surface of said stay and received in said cavity, said base having an inside wall surface defining said cavity and having a first semi-spherical dent arranged in the center of said inside wall surface and two second semi-spherical dents formed, respectively at opposite positions of said inside wall surface equally spaced from the center of said inside wall surface, said frame having a front end and a semi-spherical projection formed at said front end for engaging said first semi-spherical dent;

elastic engaging means comprising an arc-shaped leaf spring to be located in said frame and two stoppers arranged at opposite sides of said frame, respectively;

said elastic engaging means arranged in said frame to provide for engagement of said two stoppers in said two second semi-spherical dents, respectively; and

each of said two stoppers elastically engaging a respective end of said leaf spring and having a semi-spherical convex projecting through a respective end portion of said frame for engaging said respective second semi-spherical dent.

2. An inside rear view mirror as set forth in claim 1, wherein said frame is formed integrally with said stay on said upper surface of said stay.

3. An inside rear view mirror as set forth in claim 1, wherein said frame has an upper surface and a plurality of dowels formed thereon, said base having an inner surface and a plurality of holes for receiving said plurality of dowels.

4. An inside rear view mirror as set forth in claim 1, wherein a portion of said frame is provided with a provisionally fastening rib.

5. An inside rear view mirror as set forth in claim 1, wherein said frame has a semicircular shape, a center portion and a U-shaped groove on a periphery of said center portion and said center portion has a threaded hole receiving a screw for fastening said stay.

6. An inside rear view mirror for a vehicle, comprising:

a base to be secured to an interior surface of a vehicle and having a bottom surface and a cavity formed in said bottom surface;

a stay detachably mounted on said bottom surface of said base and having a lower surface and an upper surface, said stay being provided with a threaded hole formed through said stay opening onto said upper surface of the stay;

a frame integral with said stay and arranged at said upper surface of said stay and received in said cavity, said base having an inside wall surface defining said cavity and having a first semi-spherical dent arranged in the center of said inside wall surface and two second semi-spherical dents formed, respectively, at opposite positions of said inside wall surface equally spaced from the center of said inside wall surface, said frame having a front end, and a semi-spherical projection formed at said front end for engaging said first semi-spherical dent;

elastic engaging means comprising an arc-shaped leaf spring located in said frame, two stoppers arranged at opposite sides of said frame, respectively and an engaging member extending through said threaded hole from the lower surface of said stay to the upper surface of said stay;

said elastic engaging means arranged in said frame to provide for engagement of said two stoppers in said two second semi-spherical dents, respectively;

each of said two stoppers elastically engaging a respective end of said leaf spring and having a semi-spherical convex projecting through a respective end portion of said frame for engaging said respective second semi-spherical dent; and

said engaging member extending through said threaded hole for progressively pushing a center of a bent portion of said leaf spring to thereby provide for engagement of the semi-spherical convexes of said stoppers with said two second semi-spherical dents, respectively.

7. An inside rear view mirror for a vehicle, comprising:

a base to be secured to an interior surface of a vehicle and having a bottom surface and a cavity formed in said bottom surface;

a stay detachably mounted on said bottom surface of said base and having an upper surface provided with a guide groove and a hole opening onto said upper surface;

a frame detachably arranged at said upper surface of said stay and received in said cavity, said base having an inside wall surface defining said cavity and having a first semi-spherical dent arranged in the center of said inside wall surface and two second semi-spherical dents formed, respectively, at opposite positions of said inside wall surface equally spaced from the center of said inside wall surface, said frame having a front end, a semi-spherical projection formed at said front end for engaging said first semi-spherical dent and a threaded hole;

elastic engaging means comprising an arc-shaped leaf spring located in said frame, two stoppers arranged at opposite sides of said frame, respectively, and an engaging member engaged in said threaded hole and

each of said two stoppers including a hook-shaped base slidably received in said guide groove, elastically engaging a respective end of said leaf spring and having a semi-spherical convex projecting through a respective end portion of said frame for engaging a respective second semi-spherical dent.
