This application is a continuation-in-part of U.S. application Ser. No. 11/970,975, filed Jan. 8, 2008, which is a continuation of U.S. application Ser. No. 11/188,291, filed Jul. 22, 2005, now issued U.S. Pat. No. 7,316,450.
TECHNICAL FIELDThis invention relates to a deployable cover for the overhead protection of a user and more specifically a portable deployable cover for the overhead protection of a user.
BACKGROUND ARTThis invention relates to a deployable cover for the overhead protection of a person and their belongings and, more particularly, to such a deployable cover which is foldable and storable. The device is mounted on backpacks for children and adults, wheelchairs, scooters, bikes, etc. when not in use and includes many features that are attractive to all backpacks. Backpacks, wheelchairs, and other wheeled vehicles generally do not include a deployable cover providing overhead protection. Deployable covers have not been designed which are acceptable in the marketplace for various reasons. The results of this lack of adequate covers for children, hikers, cyclists and the disabled, is that they do not venture out if the existing or potential weather is not conducive to uncovered travel, with a hands free design for protection in all weather.
SUMMARY OF THE INVENTIONThe following presents a simplified summary in order to provide a basic understanding of some aspects of an exemplary embodiment. The summary is not an extensive overview of the exemplary embodiment. The summary is not intended to identify key/critical elements or to delineate scope. The sole purpose of the summary is to present some concepts in a simplified form as a prelude to the more detailed description that is presented later.
The present invention provides a foldable, hands free deployable cover with pop up features for protecting a person and their belongings in all weather. It can be stowed, flattened and collapsed, when not in use.
In its basic aspects, the foldable deployable cover of the invention includes a frame, a pliable material mounted over the frame, a case secured over the frame and pliable material when stowed, and a means to deploy the overhead deployable cover by removing the case, allowing the deployable cover to automatically extend over the user.
The frame is made of a coilable spring material which is enclosed in a sleeve which may be formed at or from the edges of the pliable material. The frame is enclosed in the sleeve forming a continuous perimeter thus allowing the frame and pliable material to be collapsed into a flattened cylindrical structure.
First and second cross supports which may be a flexible, non-biasing strap or a spring support are attached to opposing sides of the sheet of pliable material. The cross supports are configured to provide the deployable cover with a domed shape. In addition, stabilization straps which are attached to the sheet of pliable material may be attached to a person, a person's belongings, a personal transport device, or any other suitable object. The personal transport device may be, for example, a personal wheeled device, a backpack, a wheel chair, a book bag, or any other suitable device. There is also, at least one vent constructed into the pliable material.
The deployable cover may be deployed from its stowed configuration by pulling on a pull cord which is affixed to the case. When deployed, the deployable cover is at least as wide as a user's shoulders. When stowed, the deployable cover, in its flattened, cylindrical structure is narrower than the user's back.
To the accomplishment of the foregoing and related ends, certain illustrative aspects of the invention are described herein in connection with the following description and the annexed drawings. These aspects are indicative, however, of but a few of the various ways in which the principles of the invention may be employed and the present invention is intended to include all such aspects and their equivalents. Other advantages and novel features of the invention may become apparent from the following detailed description of the invention when considered in conjunction with the drawings.
The occupant space is defined by a chair having a back 18, two arms 19, and the usual footrests 21.
In accordance with normal practice, the chair 12 also includes a pair of push handles 22. It is to these push handles that the foldable cover of the invention is rigidly secured via an intermediate mount bar 23.
The foldable cover is made up of a frame 15 (described in more detail hereinafter), supporting a covering 20. The covering 20 is generally opaque although it could be transparent. In this embodiment it is generally opaque with a transparent window at the location for the back of the head of an occupant of the wheelchair. Such covering also defines small air vents at the location of the window to enable air to escape and thus prevent pressure buildup from occurring within the covering and interfering with its location over the space defined for an occupant. This is shown in
As mentioned previously, the foldable cover of this embodiment is an after market item. It is for this reason that the mount bar 23 is provided. This mount bar 23 extends between the push handles 22 and is rigidly secured in front of the portion of the same designed to receive the hands of a pusher. As is best illustrated in
Although both embodiments being described have mount bars, such a bar is really not necessary when one considers the basic aspects of the instant invention. From the broad standpoint, the foldable cover need not be an after market item and could be integrated into the chair itself with the result that the mounting bar is not needed. Even when the cover is integrated into the chair itself, it is rigidly securable to the chair. However, it is important is that the cover frame be pivotally connected for switching between a stowed or stored position on the wheelchair and a protective position in which it covers the occupant's space.
The stowed or stored position is selected to facilitate erection of the cover. While it is recognized that many disabled will not be able to erect the cover (or covers of any design at all), this position facilitates erection and permits erection by some disabled.
In the embodiment of
When the cover of the invention is moved to its stowed position, the front frame component 29 fits within the back section 28. That is, the transverse width of the front section 29 is less than the transverse width of the back section to accommodate such an arrangement, helping to provide the cover in a compact, collapsed condition when it is in its stored position.
Another important feature of the invention is that the cover extends over the full occupant space. In this connection, in this embodiment the top section made up of its components 29 and 31 are cantilevered from the back section 28. This is facilitated by including a hinged securance of the top midsection component to the back section with an interference position. This midsection is sandwiched between the back section and the front section component. When the cover is erected, this front component is, in essence, an extension of the midsection component so that the two top components are serially cantilevered from the back section.
The relationship resulting in the interference position for this embodiment is best illustrated in
As mentioned previously, the mount bar 23 assures that rigid securance to the wheelchair is achieved. As discussed previously, a pair of spaced groups of slots 24 accommodate Velcro straps or U bolts which extend around the two push handles of a wheelchair to enable the bar to be rigidly secured thereto. The cover itself is then pivotally connected to the bar, i.e., the back section 28 is so connected, to enable the cover to be moved from its protective position to its stowed position.
It will be seen from the above how the frame is designed not only to provide the desired foldability, but also to make sure that the full occupant space is covered. It is not necessary, though, that the top section be made up of a plurality of section components to provide the desired coverage. The embodiment of the invention shown in
With reference to
The foldable cover of the
Reference is made to
The top section 42 is pivotally hinged to the back section via bolts 52. That is, with reference to
As mentioned previously, the covering is only secured to the frame at the front edge of the foldable cover. The result is that when the top section of the frame is pivoted or folded to the stowed position in the direction of the arrow 53 in
The front panel 58 of the enclosure is provided with a pouch 61 for the occupant to carry various items, such as groceries. It should be noted that the flap 59 extends over the opening into the pouch.
A sun visor or the like similar to those provided in automobiles can be provided on the front of the cover to enable the occupant to obtain shade as desired.
As mentioned previously, the mount bar 44 of this embodiment is different than the mount bar of the other earlier described embodiment. As shown in
Mount bar 44 is quite versatile and can be used to mount the foldable cover (or any other desired structure) to other vehicles, such as the scooters typically used by the disabled. As shown in
It will be recognized from the above that this embodiment is particularly lightweight and is therefore especially useful with push chairs. Moreover, the foldable cover of the invention is easily moved between the fully upright condition and a stowed position.
As mentioned at the beginning of the detailed description, applicant is not limited to the specific embodiments and variations described above. For example, it may be desirable to provide two different coverings for a single foldable cover of the invention, one covering being fully transparent for use in storms and the like (provide protection without interfering with visibility) and one generally opaque for protection from the sun. It will also be recognized that the cover of the invention can be used with other wheeled vehicles. It is not limited to use with those designed for the disabled. The claims, their equivalents, and their equivalent language define the scope of protection.
Those with skill in the art would appreciate that the invention may be understood in a number of different ways. In simplest form, understanding would be understood with relation to

The device may have one or more types of cross support as shown in a cutaway. A woven material cross support 116 may extend between the side edges across the width dimension of the deployable cover 100. When deployed this cross support may rest behind a user's head keeping the cover stabilized. A spring frame cross support 122 may extend between the side edges across the width dimension of the deployable cover 100. The spring frame cross support 122 may be held in place by the stitching of the pliable material or attached by a linkage 124. In another embodiment, the spring frame cross support 122 may constructed of an injection molded plastic frame with heat pressed pliable material. The dome shape of the cover is formed by combined use of the woven material cross support 116 and a spring frame cross support 122. In one embodiment, the woven material cross support 116 has a length less than the width dimension of the deployable cover 100 where the woven material cross support 116 is attached to the deployable cover 100 and the spring frame cross support 122 has a length approximately the same as the width dimension of the deployable cover 100 where the spring frame cross support 122 is attached to deployable cover 100.
A stabilization strap 118 having a female buckle 120 may extend from a side edge proximate to the cross supports. The stabilization strap 118 may extend from the side of the spring frame to a belt of a user, to the sides of a wheeled device such as a wheelchair, a bottom of a shoulder strap of a backpack, or any portion of the personal transport device to further stabilize the deployable cover 100.
