DESCRIPTION
Throughout the following description specific details are set forth in order to provide a more thorough understanding to persons skilled in the art. However, well known elements may not have been shown or described in detail to avoid unnecessarily obscuring the disclosure. Accordingly, the description and drawings are to be regarded in an illustrative, rather than a restrictive, sense. Further, where considered appropriate, reference numerals may be repeated among the figures to indicate corresponding or analogous elements.
Provided generally is a sun visor comprising a sun shielding member joined to an adjustable support arm, said support arm further joined to a multifunctional mounting member comprising a plurality of different attachment members. In an embodiment, the plurality of attachment members comprises a clamp and a mounting blade. In an additional embodiment, the mounting member may further comprise a suction cup, allowing the sun visor to be mounted directly to a window surface. Additional attachment members may also be employed, such as a releasable adhesive patch or a hook and loop closure. The clamp allows the sun visor to be mounted to a support structure or object by being clamped to the support structure or object, while the mounting blade allows the sun visor to be mounted against a window of an automotive vehicle by insertion of the mounting blade between the inner face of the window and the weatherstripping or seal at an outer edge portion of said window.
The sun visor is intended for use to shade the eyes and/or face of a user, or to filter the light that reaches the eyes and/or face of a user. The sun visor may further be employed to shade an object being viewed by a user, such as a book or visual display. The sun visor is particularly suited for use in an automotive vehicle to protect the eyes of a driver from the glare of the sun and to thereby increase visibility for the driver. However, the sun visor could also be used to shield a passenger from the sun. When not in use in an automotive vehicle, the sun visor could also be fastened to an object such as a chair, car seat, or stroller to shield an individual sitting in said chair, car seat, or stroller from the sun. The sun visor is further suitable for use to provide shade to the pages of an item being viewed by a user such as a book or a visual display, such as a tablet screen, laptop screen, e-book reader, or smartphone screen. In this instance, the sun visor could be fastened directly to the object to be shaded, for example by fastening to the cover of a book, or the sun visor could be fastened to an adjacent object such as a chair or table. The sun visor is intended to be portable and readily positionable to allow for simple and readily adjustable positioning of the sun visor, relative to the angle of the sun, to meet the needs of the user.
A first embodiment of the sun visor 10 is depicted in FIGS. 1 and 2. The sun visor comprises a sun shielding member 12 joined to a first end of an adjustable support arm 18. In the depicted embodiment, the support arm 18 is flexible and capable of bending with a 360 degree range of movement, allowing the sun shielding member 12 to be positioned between the sun and the user or object to be shaded. The flexible support arm 18 is also shape retaining, such that the support arm 18, once bent into any particular shape, retains its shape until repositioned by a user. The opposite end of the support arm 18 is joined to a mounting member 20 comprising a clamp 14 and a mounting blade 16. In an embodiment, the jaws of clamp 14 may be of a suitable size and configuration to securely grasp the mounting arm of a rearview mirror 34 within an automotive vehicle 30. An example of the sun visor mounted within a vehicle 30 by clamping the clamp 14 to the mounting arm of a rearview mirror 34 is depicted in FIG. 6. In an embodiment, the jaws of clamp 14 may comprise a resilient, non-slip material, such as rubber, to inhibit movement of the clamp 14 relative to a support once the sun visor 10 has been clamped to the support. In a further embodiment, the jaws of the clamp 14 may be of a suitable shape and size to securely grasp an object such as a chair, child's car seat, stroller, book, or computing device.
The mounting blade 16 is substantially planar and is of a suitable thickness to allow the mounting blade 16 to be inserted along the interior face of a vehicle window 32 between the inner face of the window 32 and the weatherstripping or seal of said window 32, for example as depicted in FIG. 5. In the depicted embodiments, the mounting blade 16 is a flared blade that is wider at the end of the blade 16 that is to be inserted against the window 32 and narrower at the end of the blade that is joined to the mounting member 20. However, the blade 16 may be of any suitable shape as will readily be understood to one skilled in the art. For example, the blade 16 could be rectangular or oblong. The length of the blade 16 should be sufficient to allow the blade 16 to be inserted against a window 32 to a depth sufficient to maintain the sun visor 10 in a substantially fixed position, without appreciable wobbling or falling away from the window 32 by the sun visor 10. The clamp may be any suitable type of clamp as will readily be understood by one skilled in the art.
In the illustrated embodiments, the mounting member features a handle portion in the form of a rigid shaft 20a that extends linearly from the joint or connection with the support arm 18, with the blade 16 being a parallel extension of the shaft 20a from the distal end thereof that lies opposite the support arm 18. The shaft 20a features an integrally-defined, stationary clamp jaw 14a in the form of a curved depression or recess that is formed in one side of the shaft 20a near the distal end thereof and features serrated teeth, a resilient non-slip lining, other grip-enhancing feature, or any combination thereof. A movable second jaw 14b of the clamp is pivotally attached to the shaft 20a at a location between the curved depression of the shaft portion and the proximal end thereof that is connected to the support arm 18. The pivot axis of the second jaw 14b lies perpendicular to the shaft 20a, whereby pivoting of the jaw 14b about the pivot axis in opposing directions acts to open and close a mouth of the clamp that points toward the distal end of the shaft 20a and the blade 16 supported thereat.
The illustrated second jaw 14b features an arc-shaped portion whose concave interior defines a toothed and/or lined recess similar or identical to that of the integral first jaw on the shaft. The arc-shaped portion features the pivotal connection to the shaft 20a at one end, with the opposite free end of the arc-shaped portion being situated at the mouth of the clamp. The free end of the arc-shaped portion thus abuts against the shaft 20a near the distal end thereof when the mouth of the clamp is closed. The second clamp jaw 14b is spring biased into the closed position so as to automatically close around a rearview mirror mounting arm 34 or other object. A stub or tab projects radially outward from the pivotally connected end of the second jaw so as to extend obliquely away from the shaft toward the proximal end thereof when the clamp jaws are closed. This forms a thumb-lever 14c that is squeezable toward the shaft to temporarily open the clamp against the bias of the spring-loaded second jaw 14b. 
The plane of the flat blade 16 is parallel to the longitudinal axis of the shaft and to the pivot axis of the clamp. This plane of the blade is located at side of the shaft opposite that at which the first clamp jaw is integrally defined, whereby the shaft and clamp do not interfere with insertion of the blade into the window space of the vehicle door.
A second embodiment of the sun visor is depicted in FIG. 3. In this embodiment, the adjustable support arm 18 is joined to the mounting member 20 by a ball 22 and socket 24 assembly. In the illustrated embodiment, the socket 24 is joined to the mounting member 20, though in a non-illustrated embodiment the socket 24 could be joined to the adjustable support arm 18 with the ball 22 joined to the mounting member 20. The socket 24 may be fastened to the multifunctional mounting member 20 or support arm 18, or the socket 24 may be integral with the multifunctional mounting member 20 or support arm 18. The ball 22 is rotatable within the socket 24, allowing the support arm 18 to be moved to position the sun shielding member 12 between the sun and a user or object to be shielded. In an embodiment, the ball 22 and socket 24 assembly comprises a releasable ball joint, such as a magnetic ball joint, while in other embodiments, the ball 22 may be permanently maintained within the socket 24.
In a further embodiment, the adjustable support arm 18 may be an extendable arm, allowing the support arm 18 to be extended or retracted as needed to position the sun shielding member 12 at a desired position, which may be proximal to the mounting member 20 or more distant from the mounting member 20. For example, the support arm 18 may comprise an extendible arm such as a telescopic arm, a foldable arm comprising pivotally joined sections, or an accordion arm. In an embodiment, the full length of the support arm 18 may be extendible while in another embodiment at least a portion of the support arm 18 is extendible. The support arm 18 may comprise both extendible and non-extendible portions as desired.
In another embodiment, depicted in FIG. 4, the sun visor 10 may further comprise a suction cup 26 joined to the mounting member 20, allowing the sun visor 10 to be mounted to a substantially smooth and planar surface, such as the face of a window 32. In an embodiment, the suction cup 26 may positionable along the length of the mounting member 20 and/or the suction cup 26 may be rotatable around the longitudinal axis of the mounting member 20 to allow a user to adjust the positioning of the suction cup 26 to allow for optimized placement of the sun visor 10 once mounted. In another embodiment, the position of the suction cup 26 may be fixed relative to the mounting member 20.
The sun shielding member 12 comprises a sheet or disk of sun blocking or sun filtering material that is sufficiently rigid to maintain its shape without drooping. The size and shape of the sun shielding member 12 may be selected as desired, but the area of the face of the sun shielding member 12 should be sufficient to provide shade or filtered light to at least the eyes of a user. As used herein, the term sun blocking material refers to a material that blocks at least a substantial portion of the visible light spectrum and provides shade from the sun. Examples of suitable sun blocking materials include but are not limited to opaque materials such as plastic and metal. As used herein, the term sun filtering material describes a material that is transparent or semi-transparent; allowing some degree of visibility through the sun shielding member, while filtering out a portion of the UV and/or visible light spectrum. An example of a suitable sun filtering material is tinted plastic. In another embodiment, the sun shielding member 12 may comprise an opaque sun blocking material comprising a plurality of perforations to allow limited light transmission through the sun shielding member 12.
In an embodiment, the sun shielding member 12 blocks or filters a portion of the visible light spectrum to provide visual relief from sun glare. In a further embodiment, the sun shielding member 12 comprises a light and thin sheet material to minimize the weight of the sun shielding member 12. In yet another embodiment, the sun shielding member 12 comprises a UV-resistant material. In a still further embodiment, the sun shielding member 12 comprises an impact-resistant and/or shatterproof material.
In an embodiment, the multifunctional mounting member 20, support arm 18, and/or sun shielding member 12 may comprise a bio-based polymer derived from a renewable biomass source, such as vegetable oil or starch. In a further embodiment, the multifunctional mounting member 20, support arm 18, and/or sun shielding member 12 may comprise a bio-based polymer that is biodegradable.
In an embodiment, two of more of the major components of the sun visor: i.e. the mounting member 20, the adjustable arm 18, and the sun shielding member 12, may be releasably joined to one another; allowing the sun visor to be disassembled for shipping or storage and assembled for use. In an embodiment, the mounting member 20 may be detachable from the adjustable arm 18 and/or the sun shielding member 12 may be detachable from the adjustable arm 18. The releasably joined components may be joined by any suitable releasable fastener, as will readily be understood to one skilled in the art. For example, the components may be joined by a threaded joint, an interference fit joint, a magnetic joint, and/or a ball detent.
In the illustrated embodiments, the adjustable support arm 18 is joined to a face of the sun shielding member 12, however in other embodiments the adjustable support arm 18 may be joined to at least one side edge or side edge portion of the sun shielding member 12.
