Automobile sun visor with electromechanical sun shade and methods of use thereof
View Patent ↗An automobile sun visor with an electromechanical sun shade device preferably comprising an elongated housing with a generally tear-shaped profile that is adapted for pivotally-adjustable installation at essentially any location proximate the interior roof of a vehicle and that attractively accommodates all necessary elements of the device therewithin, a scissor-type extension mechanism with interdependent, multi-stage frame support layers that evenly and supportively extend and adjust to a plurality of lengths, a two-layer screening system that surrounds the extension mechanism on all sides via a releasable connector, and that is adapted for preferential variation of interior versus exterior display during deployment, and a motorized control system with guide elements.
1. A vehicle sun visor device, comprising:
a housing with an interior compartment;
means for attaching said housing to a vehicle;
an extendable frame comprising one or more X-shaped stages and push rollers;
means for frame extension; and
a dual-layer screen, wherein a first layer of said screen is positioned to cover a first surface of said extendable frame and a second layer of said screen is positioned to cover a second, opposing surface of said extendable frame;
wherein extension of said frame coincidentally extends said dual-layer screen, wherein retraction of said frame coincidentally retracts said dual-layer screen by means of a spring-loaded roller, and wherein said retracted frame and screen are contained within said housing;
wherein said means for frame extension further comprises an elongate support member, one or more slidable members carried proximate said elongate support member, and a threaded shaft, wherein said extendable frame is pivotally secured to said one or more slidable members, and wherein at least one of said slidable members is internally threaded and moveable relative to an axial length of said elongate support member, according to rotation of said threaded shaft; and
a rubber pulley support member carried proximate said elongate support member, and wherein said rubber pulley support member, said threaded shaft, and said elongate support member extend from a first end to a second end of said housing.
2. The vehicle sun visor device of claim 1 , wherein said housing is tear-shaped.
3. The vehicle sun visor device of claim 1 , wherein said means for attaching said housing to a vehicle is a ball-and-socket joint and mount.
4. The vehicle sun visor device of claim 3 , wherein said ball-and-socket joint and mount are spring-loaded.
5. The vehicle sun visor device of claim 1 , further comprising one or more spring members positioned between said interconnected layers.
6. The vehicle sun visor device of claim 1 , wherein said first layer of said screen and said second layer of said screen differ in appearance.
7. The vehicle sun visor device of claim 1 , wherein said dual-layer screen further comprises means for reseal able engagement of said first layer and said second layer proximate a peripheral edge of each said layer.
8. The vehicle sun visor device of claim 7 , wherein said means for releasable engagement is selected from the group consisting of a zipper, a slide lock, and hook and loop fastener.
9. The vehicle sun visor device of claim 1 , wherein said inner compartment of said housing further comprises a lip, wherein said extendable frame receives support therefrom.
10. The vehicle sun visor of claim 1 , wherein said one or more X-shaped stages comprise two interconnected layers.
11. The vehicle sun visor of claim 1 , wherein said one or more X-shaped stages comprises two parallel units.
12. A sun visor, comprising:
a spring-loaded roller carried within a housing;
two screens with a proximal end wound around said spring-loaded roller and a distal end attached to plurality of push rollers;
a scissor-type support mechanism carried within said housing and extendable out of said housing through an opening therein, wherein said screens are carried on opposing surfaces of said support mechanism and said screens are unwound and extended coincident with extension of said support mechanism; and
a screen engagement mechanism, wherein said mechanism secures a plurality of screen edges of said screens together upon exit from said housing.
13. The sun visor of claim 12 , further comprising:
a motor;
a cylinder chamber with one or more fixed arm connectors and one or more slidable arm connectors, wherein a first stage of said scissor-type support mechanism is attached to one said fixed arm connector and one said slidable arm connector;
a threaded shaft, wherein said one or more slidable arm connectors is moveable thereon;
a drive train operatively connected between said motor and said threaded shaft, wherein a first mode of motor operation rotates said shaft and moves said one or more slidable arm connectors, contracting said scissor-type support mechanism and extending same, and wherein a second mode of motor operation rotates said threaded shaft in a direction opposite to that of said first mode and moves said one or more slidable arm connectors in a direction opposite that of said first mode, widening said scissor-type support mechanism and contracting same.
14. The sun visor of claim 13 , wherein said cylinder chamber has a slit defined lengthwise, at least a portion of an axial length of said cylinder chamber.
15. The sun visor of claim 13 , wherein said threaded shaft comprises two lengthwise segments of threading, and wherein said two lengthwise segments of threading are opposingly directed.
16. A vehicle sun visor device, comprising:
a housing with an interior compartment;
means for attaching said housing to a vehicle;
an extendable frame comprising one or more X-shaped stages and push rollers;
means for frame extension; and
a dual-layer screen, wherein a first layer of said screen is positioned to cover a first surface of said extendable frame and a second layer of said screen is positioned to cover a second, opposing surface of said extendable frame;
wherein extension of said frame coincidentally extends said dual-layer screen, wherein retraction of said frame coincidentally retracts said dual-layer screen by means of a spring-loaded roller, and wherein said retracted frame and screen are contained within said housing;
wherein said means for frame extension further comprises an elongate support member, one or more slidable members carried proximate said elongate support member, and a threaded shaft, wherein said extendable frame is pivotally secured to said one or more slidable members, and wherein at least one of said slidable members is internally threaded and moveable relative to an axial length of said elongate support member, according to a rotation of said threaded shaft; and
wherein said elongate support member has a lengthwise slit therein, a portion of each of said one or more of said slidable members is slidable within said slit, and a length of said slit is more than a length of said portion of each of said slidable members to facilitate lengthwise movement of each of said one or more of the slidable members in response to said rotation of said threaded shaft.
