Turn-over type rearview door mirror

A turn-over type rearview door mirror for a vehicle, comprising:

• a stay member securely attached to a vehicle door and carrying a base member;
• a mirror visor pivotally supported by said base member around a vertical retraction pivot axis;
• detent means for retaining said mirror visor at a fully extending position and at a fully retracted position;
• a rearwardly facing mirror member received in said mirror visor and pivotally supported so as to be angularly movable around a horizontal axial line and a vertical axial line;
• knob means projecting form said door into a passenger compartment;
• a vertical driven rod disposed in parallel with said retraction pivot axis and guided so as to be rotatable around and slidable along its central axial line;
• linkage means for converting a lateral rotative movement of said knob means around a vertical axial line and a rotative movement of said knob means around another axial line extending substantially perpendicularly to said vehicle door into said rotative movement and said sliding movement of said vertical driven rod, respectively;
• an arm member extending laterally from an upper end of said vertical driven rod;
• a connecting rod unit having on end pivotally attached to a free end of said arm member, and having another end pivotally attached to a reverse surface of said mirror member at an area which is displaced form an intersection of said horizontal axial line and said vertical axial line of said mirror member, such that said sliding movement and said rotative movement of said vertical driven rod is transmitted via said arm member into angular movement of said mirror member around said horizontal axial line and said vertical axial line, respectively;
• and,
• brake means interposed between said mirror member and said mirror visor for selectively retaining a current angular position of said mirror member with respect to said mirror visor when said mirror visor is retracted from a neutral position around said retraction pivot axis.

A turn-over type rearview door mirror for a vehicle, comprising:

• a stay member securely attached to a vehicle door and carrying a base member;
• a mirror visor pivotally supported by said base member around a vertical guide rod;
• detent means for retaining said mirror visor at a fully extended position and at a fully retracted position;
• a rearwardly facing mirror member received in said mirror visor and pivotally supported so as to be angularly movable around a horizontal axial line and a vertical axial line;
• a lateral rod extending through said vehicle door so as to be rotatable around and slidable along its central axial line;
• knob means coupled with an inner end of said lateral rod via an actuation linkage mechanism for converting a lateral rotative movement of said knob means around a vertical axial line and a rotative movement of said knob means around another axial line extending substantially perpendicularly to said vehicle door into said sliding movement and said rotative movement of said lateral rod, respectively;
• a vertical driven rod provided adjacent an outer end of said lateral rod and guided so as to be rotatable around and slidable along its central axial line;
• a lateral arm member extending laterally from an upper end of said vertical driven rod;
• a vertical guide rod extending substantially in parallel with said vertical driven rod;
• a conversion arm supported by said vertical guide rod at a middle part thereof so as to be rotatable about and slidable along a central axial line of said vertical guide rod, and provided with a first end engaged with a free end of said lateral arm member for converting a rotative and vertical movement of said vertical driven rod transmitted thereto into a rotative and sliding movement of said conversion arm via said lateral arm member;
• a connecting rod unit having one end pivotally attached to a second end of said conversion arm, and having another end pivotally attached to a reverse surface of said mirror member at an area which is displaced from an intersection of said horizontal axial line and said vertical axial line of said mirror member, such that said sliding movement and said rotative movement of said conversion arm is transmitted into angular movement of said mirror member around said horizontal axial line and said vertical axial line, respectively;
• and
• a clutch unit interposed between a free end of said lateral arm member and said first end of said conversion arm, comprising a cam part provided at said first end of said conversion arm, a cam follower part provided at said free end of said lateral arm member for cooperating with said cam part, and a spring member urging said cam follower part toward said cam part so as to elastically allow said conversion arm, along with said mirror visor, to be turned around said vertical guide rod against a biasing force of said spring member which tends to restore said conversion arm to a neutral position with respect to said vertical guide rod.
