Collapsible Sunshade

Abstract

A vehicular sunshade has a shade panel and an articulating support frame. The panel is made of a flexible opaque material. The frame has extendible arms, a central support, and a yoke. The yoke surrounds the central support and slides relative thereto between distal and proximal ends thereof. The flexible arms are hingedly affixed to the yoke and extend outwardly therefrom. The panel is affixed to the frame. A latch near to the central support's distal end engages the yoke to retain the yoke there-at, to thereby retain the sunshade in an expanded configuration with the flexible arms extended outwardly to cause the panel into a horizontally elongated rectangular planar shape. The latch may be depressed to allow the yoke to slide towards the central support's proximal end to allow the flexible arms to bend at the elbows such that the sunshade is transformed into a compacted storage configuration.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS

[0023] Referring to FIGS. 1 through 10, an exemplary sunshade 100 in accordance with or useful in practicing the invention is shown, in conjunction with a typical vehicle 200.

[0024] Sunshade 100 includes a shade panel 102 and a preferably metal articulating support frame 104.

[0025] The panel is preferably a flexible opaque material, such as a fabric or polymeric film, which is selected from materials having high resistance to sun damage and which block the through-passage of sunlight, especially in the ultraviolet spectrum.

[0026] The frame is made of eight flexible arms, four corner arms 106 and four shorter inboard arms 108, a central support brace 110, and a yoke 112.

[0027] The support brace includes a cylindrical pole portion 114 with a shade end 116 and a support end or bracing end 118.

[0028] The yoke surrounds the pole portion and is adapted to slide freely up and down relative thereto.

[0029] The eight flexible arms are hingedly affixed at their inner ends 120 at equally spaced intervals around the yoke and extend outwardly therefrom in a spider web configuration towards their outer ends 122.

[0030] The flexible arms each include an inner flexible elbow 124 disposed approximately one third of the arm's length from the yoke, that allows the arm to bend inwardly there-at, and an outer flexible elbow 126 disposed approximately halfway of the arm's length from the yoke, that allows the arm to bend inwardly there-at.

[0031] The panel is affixed to the frame only at points at the distal shade end of the support brace, the outer ends of each flexible arm, and adjacent the outer flexible elbows. Such affixation is preferably by stitching, but may be accomplished by any other known means.

[0032] Referring to FIG. 6, the cylindrical pole portion includes latch 128 near to its shade end which engages the yoke to retain the yoke when it is slid fully thereto, and thereby retains the sunshade in the expanded configuration of FIGS. 1 and 4. The latch is preferably made of a flexible metal, such as spring steel.

[0033] As seen in FIG. 7, by depressing the latch inwardly into the pole portion, the yoke is allowed to slide down the central pole portion to allow the sunshade to be transformed into its compacted storage configuration of FIGS. 3 and 4.

[0034] As best seen in FIG. 8, the support brace has is arranged to adapt to and secure the sunshade within a large variety of vehicles. The pole portion telescopes to adjust its length. A common twist-extend-untwist arrangement fixes the pole portion at the desired length. A flexible gooseneck portion 130 at its proximal support end allows the brace to be shaped and seated against any available nearby feature within the vehicle, preferably the vehicle's dashboard 202, to thereby squeeze the sunshade firmly into position and hold it there until removed. Such gooseneck mechanisms are well known and commonly used in such things as desk lamps to allow lamp to be directed as desired. The specific constructions of such mechanisms are beyond the scope of this disclosure, and the particular type of such well-known mechanisms used should not be a limiting feature of the invention. As the term is used herein, a gooseneck mechanism is simply any universally flexible elongated component that is rigid enough to remain in the position to which it is flexed until forcefully flexed into some other shape. Gooseneck portion 130 of the is capped by a rubbery foot 132, which provides friction to prevent slipping and protects the vehicle.

[0035] When the sunshade is expanded and the shade panel is positioned against the inside of the windshield 204 of the vehicle 200, the pole portion is telescoped and fixed to the desired length, and the gooseneck portion is bent to force the rubbery foot against the dashboard, and the sunshade it thereby held in position, as seen in FIGS. 1 and 8, until removed.

[0036] Referring to FIG. 8A, because many vehicles have their rearview mirrors affixed near to the center top of their windshields, the shade panel includes a stretchable sub-panel 136 in that region, this allows the shade panel to conform around or over the mirror 206 when required. The sub-panel may be made of a material such as spandex.

[0037] Once use of the sunshade is concluded, the rubbery foot is simply pulled from the dashboard, the pole is shortened, the latch is depressed, the yoke is retracted towards the support end of the pole portion, and the frame and shade panel are folded into the compacted state of FIG. 3 for storage. Strap 134 wraps around the folded panel and secures to itself by hook/loop fastening or metal snaps to retain the sunshade in this compacted state.

[0038] FIGS. 9 and 10 show the optional use of a decorative flexible layer 138 adhered to the windshield-side of the sunshade panel to provide an ornamental effect to passersby. The decorative layer may be removable and replaceable, such as by hook/loop fastening or metal snaps, so that a consumer may purchase numerous different layers for say various days of the week or to express different messages. The layers may be customizable to thereby allow the user to create an identifier, an advertisement, or a message according to their needs.

[0039] It should be noted that the embodiment shown herein is not intended to limit the scope of the invention. The invention therefore only be limited by the follow claims, including any equivalent interpretation to which they are entitled.
