ABSTRACT:
FIELD OF THE INVENTION
This invention is directed to a canopy structure which has a canopy to provide sun and/or wind shade in a particular selected area. The support for the canopy is adjustable to permit selected movement of the canopy to provide the shade in the desired area. The support permits mounting of the canopy on children's strollers and carriages, as well as wheelchairs. The canopy structure is also configured to mount on various bases like fixed mounts such as beach and garden chairs as well as on porch or patio rails.
BACKGROUND OF THE INVENTION
It is well known that, when persons are outdoors and exposed to solar radiation, there are health risks. Excess solar radiation over a long period increases the chances of skin cancer. Excess solar radiation over a short period causes burning of the skin. In serious cases, one or more layers of skin peel away. The harmful solar radiation incident at the earth's surface is increasing.
It is necessary to shade those persons outdoors from excessive solar radiation. Adults often wear clothing and hats for this purpose. In addition, there are umbrellas and parasols. Children's strollers often have panels which are hinged to the stroller side rails. Such panels have several difficulties which prevent convenient use. They are movable from a raised position to a folded position and are not significantly adjustable for different sun angles. Another problem is that the person driving the stroller (usually the mother) wants to see the infant (usually her child) in the stroller. The present stroller panels cut off this view when raised.
Shelter from the wind is also needed to protect infants in child seats or strollers as well as protect others seated in open windy places.
SUMMARY OF THE INVENTION
In order to aid in the understanding of this invention, it can be stated in essentially summary form that it is directed to a canopy structure which is supportable on a base such as a stroller or some other base structure by means of two flexible supports attached both to the canopy and the base. The canopy is preferably a flexible sheet of polymer fabric of oval configuration, which is stretched by a resilient band at its edges. The supports grasp the edges of the canopy and can grasp two other base members.
It is, thus, a purpose and advantage of this invention to provide a canopy which is supported by two flexible supports so that the canopy can be positioned in the most effective way to achieve both shade or wind shelter of the desired space and view of the shaded space.
It is another purpose and advantage of this invention to provide the aforementioned shade and wind canopy without overly limiting the ability of the child to have a visual field of significant scope to allow the child the satisfaction of one of the reasons for taking the child on walks.
It is another purpose and advantage of this invention to provide a canopy which can be folded into substantially one-third of its open area by employing a flexible canopy sheet and a resilient band in the edges thereof which can be folded upon itself into three loops.
It is another purpose and advantage of this invention to provide two flexible supports supporting the canopy with respect to the base which are sufficiently long so the canopy can be brought down to the side of the base to shelter the base from lateral sun or wind and permit visibility from above.
It is a further purpose and advantage of this invention to provide two flexible supports for the canopy wherein the two flexible supports are each formed of ball tube to achieve adequate support for the canopy together with a wide choice of canopy positioning.
It is a further purpose and advantage of this invention to provide a canopy which can be employed on a number of different base structures, particularly including children's strollers, beach chairs and the like.
It is a further purpose and advantage of this invention to provide a canopy structure which is inexpensive to manufacture so that it can be used widely, and so that it can be easily and conveniently utilized.
Other purposes and advantages of this invention will become apparent from a study of the following portion of the specification, the claims and the attached drawings.
