Description

FIELD OF THE INVENTION

The present invention relates to an accessory wheelchair shelter adapted to universally install onto the framework of an electric wheelchair. The wheelchair shelter of the present invention comprises: a frame structure having: a chair-attaching portion, a pair of vertical struts, and a canopy frame, a sheltering cover having: a canopy, a front-side curtain, and a rear curtain. The sheltering cover is adapted with strategic portions thereof made of a clear and resilient material thus allow satisfactory viewing area to the outside of said cover. Once assembled—by means of zippers along all mating edges—the wheelchair shelter of the present invention thereby provides protection against sun, snow, rain and the like thus allowing greater freedom, protection and comfort to persons utilizing said wheelchairs.

BACKGROUND OF THE INVENTION

Unlike conventional road vehicles, wheelchairs are and have been to date bare to the elements. The lack of such shelter has long prevented persons utilizing wheelchairs from the freedom to travel outdoors when conditions are less than desirable.

The inventor—also a wheelchair user—sought to provide the significant mass of like users, with a wheelchair shelter that is non-obtrusive, lightweight, aesthetically pleasing, and especially protectively functional against the elements.

Thus the inventor presents your commissioner with a wheelchair shelter that is indeed non-obtrusive, lightweight, aesthetically pleasing, and that functionally protects users against the sun, snow, rain and the like.

One attempt in prior art—in particular U.S. Pat. No. 3,709,553—teaches of a golf cart rain coat wherein the invention depicts a combination golf cart AND a rain coat for same. The invention fails to enable users to adapt a similar arrangement to any existing electric wheelchair thus again failing to satisfy the mandate of the present invention.

SUMMARY OF THE INVENTION

It is thus the object of the present invention to provide wheelchair users with a wheelchair shelter that is non-obtrusive, lightweight, aesthetically pleasing, and especially protectively functional against the elements.

In one aspect of the invention, the shelter of the present invention is fabricated using materials protected against UV rays.

In another aspect of the invention, the canopy portion may incorporate a removable cover over a clear roof window.

In a further aspect, the chair-attaching portion of the shelter of the present invention may be adapted to engage to a manual wheelchair.

In yet another aspect of the invention, an attached trailing wagon—also sheltered—may be provided to further enhance the freedom benefits.

Accordingly, the shelter of the present invention therefore provides wheelchair users with a shelter that is non-obtrusive, lightweight, aesthetically pleasing, and protectively functional against the elements.

Although the preferred embodiment illustrates the use of the present shelter in conjunction with wheelchairs, the utility of the present invention includes but is not limited to such wheelchairs.

The front-side curtain 8 is adapted with a dear and resilient front window 12 across a substantially panoramic area thereof allowing optimal viewing area to the outside through said front-side curtain 8. The base portion 14 of the front-side curtain 8 is made of a durable flexible opaque material extending only near ground level. Both left and right termination panels 16 and 17 of the front-side curtain 8 are adapted with zippers 20 at each vertical extremity, which mate with zippers 20 at the vertical extremities of the rear curtain 10 thus securing the front-side curtain 8 and the rear curtain 10 into a full perimeter shelter. For added viewing area, smaller flexible windows 21 are added to the left and right termination panels 16 and 17 of the front-side curtain 8. Similarly, corner windows 22 are provided in the upper portion of the rear curtain 10. Furthermore, a ventilation screen 23—having a flip-up cover 27 on the outside of the shelter—is provided to enable proper air passage through the shelter. Still referring to FIG. 1, the canopy portion 6, which is securely yet removably attached to the canopy frame, is also adapted with a zippered lower perimeter where said zipper mates with a zipper 24 at the very top edge of both the front-side curtain 8 and the rear curtain 10 thus effectively suspending both now-combined curtains 8 and 10 from the lower edge of the canopy portion 6.

Turning now to FIG. 2, a perspective view from above of the frame structure of the wheelchair shelter of the present invention wherein the structure comprises; two vertical struts 4 joined together at the bottom by a horizontal member 3, a chair-attaching portion 2 having two horizontal members near the lower-mid portion of each vertical strut 4 extending frontwardly to engage with the wheelchair's structure for rigid securement thereto, a canopy frame 5 having two side members 9 with a length substantially long enough to extend the canopy further than the rearmost and frontmost usable areas a wheelchair and occupant may occupy, and front and rear joiner members 11 and 13 attached to the side members 9 thereby forming a rectangular canopy frame 5 by which a canopy will be supported. Two diagonal struts 7 are provided to further rigidify the canopy frame 5 to the vertical struts 4.

FIG. 3, illustrates a cross-sectional view taken along lines 3-3 of FIG. 1 of the wheelchair shelter of the present invention wherein the perimeter framework 9 of the canopy frame 5 is adapted with a plurality of male snap fasteners 25a fixedly attached to the lower surface of said framework 9 so as to align with mating female snap fasteners 25b attached to a continuous tab 26 within the inner upper portion of the canopy 6. A short perimeter skirt 15 is also fixedly attached to the perimeter of the canopy 6, while a zipper 24, also fixedly attached to a mid portion inside said skirt 15, provides means to suspend the curtains 8-10. The lower portion of the skirt 15 extends below the zipper 24 thus forming a rain/snow shield 19 therewith.

Turning now to FIG. 4, a front elevation view of the front/side curtain portion of the wheelchair shelter of the present invention wherein a general pattern arrangement is depicted to include: a clear and resilient front window 12 across a substantially panoramic area thereof allowing optimal viewing area to the outside, a base portion 14 made of a durable flexible opaque material, left and right termination panels 16 and 17, smaller flexible windows 21, zippers 20 at each vertical extremity, and a top zipper 24.

Referring now to FIG. 5, a rear elevation view of the rear curtain 10 of the wheelchair shelter of the present invention wherein again a general pattern arrangement is depicted to include: corner windows 22, a ventilation screen 23—having a flip-up cover 27, zippers 20 at each vertical extremity, and also a top zipper 24.

Turning now to FIG. 6, a partial perspective view of the rear curtain 10 of the wheelchair shelter of the present invention, further illustrating the rear ventilation screen 23—having a flip-up cover 27 located between the two corner windows 22. The perimeter of the ventilation screen 23 is adapted with hook and pile fastener 28 so as to enable positive closure of said flip-up cover 27. Additionally, said cover 27 can be held in the opened position by simply joining the hook and pile fastener at any level along the height of said screen 23.

Turning to FIGS. 7 and 8, FIG. 7 a perspective view from above of the sheltered trailing wagon, and FIG. 8 a partial perspective view of the canopy of the trailing wagon of the present invention comprising; a common wagon 30 adapted with leg supports 31 supporting a wagon canopy structure on which a wagon canopy 32 rests. The leg supports are collapsible to various heights so as to allow the flexibility of choosing between high or low canopy heights. When the canopy 32 is arranged in a low height, and array of lower female snaps 36 can be fastened to mating male snaps 37 thereby generally enclosing the contents of the trailing wagon 30. Furthermore, a zippered access door 33 is provided at the very top portion of said canopy 32. The zipper 34 generally only travels in a U pattern, leaving the un-zipped portion to act as a hinge for the access door 33. Conversely, when the canopy 32 is arranged in higher position, the canopy's flaps 38 can be tucked upwardly and held in such fashion by means of upper and lower male and female snaps 35 and 36.

Upon referring to the drawing figures and the above specification, it can be understood that the present invention provides wheelchair users with a shelter that is non-obtrusive, lightweight, aesthetically pleasing, and protectively functional against the elements. And with the addition of the trailing wagon, the user can also transport an impressive amount of content, and perhaps even take a child for a stroll!
