1. Field of the Invention
This application is related to mechanisms for avoiding solar radiation in general, and a compact dome-like device for accomplishing the same in particular.
2. Description of the Related Art
Various portable mechanisms for providing shade from solar radiation have been proposed in the literature. One illustration of such a mechanism is found in U.S. Pat. No. 5,368,852, issued to Dean. The combined sunbather shade and carrying case therein may be used for providing shade to a selected bodypart for a user lying on a flat surface, or a lawn chair.
One disadvantage of the shading mechanism as taught in Dean is that, while allowing for a compact means of transporting a sunshade, Dean provides no separation between the surface upon which the user is situated and the body part sought to be shaded. In addition, the “substantially C-shaped configuration” of Dean limits its flexibility in terms of how it can be positioned to avoid solar radiation from various angles as the position of the sun changes relative to the user.
Another problem with the apparatus as described in Dean relates to the complexity with which one is required to use the mechanism. For example, using the apparatus in Dean for avoiding solar radiation requires one to “remove flexible wire component 14 from within the pouch formed by panels 4 and position tubing 12 between panels 4 so that the joined arcurate perimeters of panels 4 snugly fit against tubing 12.” After this step, the user must next situate the mechanism in an appropriate manner to perform its intended shading function. Thereupon, to return the device to a condition suitable for use as a carrying case, the reverse steps need to be taken. Accordingly, to achieve the objective of solar shading via the use of a compact device, the Dean apparatus presents an unduly complicated solution.
These and other problems with prior art shading systems are addressed in the context of the present invention, described in further detail below.
A collapsible solar shade is disclosed for conveniently and effectively avoiding solar radiation on a user's body parts (or other objects) including, for example, the face, neck, and decollete. The present invention includes a bottom disk, preferably oblong, which forms the base of the solar shade. Disposed along the perimeter of the bottom disk is a first malleable element, such as a wire, that may be collapsed as shown herein, but otherwise is situated to maintain the dome-like shape of the mechanism. The bottom disk provides separation between an object or body part sought to be shaded on one hand, and a surface upon which the solar shade may be placed on the other hand. The present invention further includes a top panel oblong disk, with the respective shorter edges of the top oblong disk attached to the respective shorter edges of the bottom oblong disk. Also disposed along the perimeter of the top panel oblong disk is a second malleable element, such as a wire, that may be collapsed as shown herein, but, like the bottom disk, is otherwise is situated to maintain the dome-like shape of the mechanism. In an alternative configuration, the bottom disk is formed without using a malleable element. In either implementation, the result is that the top panel oblong disk forms a convex dome-like shape.
In another embodiment, an additional shading flap is attached substantially along the perimeter of one of the longer edges of the top panel oblong disk. The flap optionally contains a Velcro or similar attachment, with a corresponding Velcro attachment disposed at the top edge of the top panel oblong disk. The flap can then be placed in a “rolled-up” configuration using the corresponding Velcro attachment when not in use.
The present invention provides, by a simple twisting and pressing means, for collapsing of the solar shading mechanism as described herein. The collapsed mechanism may then be placed in a suitable containment mechanism, such as a simple circular fabric pouch, for easy transportation and access thereto.
Yet other advantages and features of the present invention are set forth in the Detailed Description, Figures, and claims to follow.
In general, in one aspect, the present invention includes a collapsible solar shade for conveniently and effectively avoiding solar radiation on a user's body parts (or other objects) including, for example, the face, neck, hands, feet, and decollete. In another aspect, the collapsible solar shade may include an adjustable pull down flap for additional shading. In still another aspect, the collapsible solar shade may be efficiently stored in a compact containment means such as a pouch for the convenience of the user.

In this manner, the material used in the present invention may be structured such that the domed tent is substantially effortlessly collapsible for easy and efficient storage in a pouch or other containment mechanism. Conversely, when a user is ready to use the solar shade, he or she can simply remove it from the containment pouch and the shade will automatically pop up to its full domed-tent like position for immediate use. An embodiment of the collapsing technique is further discussed with reference to FIGS. 5A-D, below.
Other configurations may contemplate the use of multiple segments of malleable wire 7 or of wire 6, with each end preferably coupled together, to comprise the wire 7 or the wire 6 in
Shown in
In an alternative embodiment of the present invention, the segment of malleable wire 7 is not used. Instead, the rigidity and malleable nature of the wire 6 is used by itself to maintain the solar shade in its uncollapsed, dome-like structure. In this alternative embodiment, the non-elongated edges of bottom disk 1 are connected to the respective non-elongated edges of top disk 2, such as through standard sewing or equivalent techniques, similar to that described in
The embodiment as described in
Finally, the user folds over one segment of the “figure eight” over the other segment, and uses his or her hands to compress the apparatus.
It should be noted that, while
Various applications and embodiments of the solar shade are now discussed. The size of the solar shade may vary depending on the particular application, but in general, to further the benefits of ease of transport, collapsibility and use, the solar shade may be compact and not bigger than the specific application for which it is designed. One typical application of the solar shade is with respect to a sunbather who wishes to protect his or her face and neck from exposure to the sun. In this application, the user may place the dome-like structure on a substantially leveled surface such as a floor, sunbathing chair, recliner, the ground, sand, and the like. The user may then situate himself or herself by placing the head underneath the shaded surface and on top of the disk 1 (e.g.,
In the above-described configuration, the solar shade may, by way of example, be 20 inches high at its peak, and approximately 16 inches in length at the base. These figures are for illustrative purposes only, as it may be contemplated by those in the art that the specific dimensions are dependent upon design detail and not critical to the present invention.
The benefits of the flap 3 illustrated with respect to
As noted above, the size of the solar shade may accordingly vary depending on the needs of the user and the desired application. As another illustration, another solar shade that may be used to cover larger or smaller objects (whether a user's body parts or other objects or materials such as a cooler) may be constructed larger or smaller, respectively, to accommodate the variations in possible applications.
As described above, the user or recreational sunbather may rest the head on the base disk 1 (
In another embodiment of the present invention, the base disk 1 (
In still another embodiment, the base disk 1 may incorporate an “air bladder” and a corresponding standard plug that the user can inflate as desired. Thereafter, when the user wishes to recollapse the solar shade (for example, for reinsertion into the circular pouch), the user can simply open the plug to release the air) and then perform the standard procedures discussed above for collapsing the pouch.
Further, other materials may be equally suitable for forming the perimeters or edges of the disks such as, for example, malleable plastic rods, rubber tubing, or another appropriate structure that enables the solar shade to maintain its natural, open position and, where appropriate, to collapse for insertion into the pouch.
Still different embodiments may be contemplated wherein the present invention can be constructed using additional material. For example, it may be appropriate to insert an additional flap or partially-removable disk at the back side of the solar shade, creating in effect a closed environment. This additional fabric may act as an extra shield to prevent excessive exposure to the sun, particularly as the angle of the sun moves with respect to the sunbather. In these embodiments, the extra cloth or disk should be constructed in a way so as not to restrict the naturally collapsible form of the solar shade (See, for example,
In the manufacturing of the solar shade, the oblong disks that comprise the apparatus in this disclosure preferably constitute discrete segments of material attached together by an appropriate means as described above. In some instances, they may actually originate from a single piece of material to form what is in effect the equivalent of two oblong disks and a flap. In this alternative configuration, the malleable metal wires may then be inserted at the appropriate locations via a standard sewing process or other known methods.
The color of the apparatus according to the present invention may be varied in any color spectrum or combination thereof, and appropriate designs and logos may be placed on the apparatus and accompanying pouch. In addition, clamps or similar materials may be included to secure the solar shade onto a sunbathing chair or other surface, such that the solar shade will remain firmly in place.
The foregoing description of the preferred embodiment of the invention has been presented for the purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form disclosed. Many modifications and variations are possible in light of the above teaching. It is intended that the scope of the invention not be limited by this detailed description, but by the claims and the equivalents to the claims appended hereto.
This application claims priority to provisional U.S. Patent Application No. 60-692130, filed Jun. 20, 2005, and which is incorporated by reference herein in its entirety.
