Description




BACKGROUND OF THE INVENTION




This invention relates generally to a wheelchair container and more particularly, to a container for a wheelchair that protects it from damage during air travel.




Under the Disability Act, airlines are required to transport wheelchairs free of charge for the general public. In fact, roughly 6.4 million people per year travel with their wheelchairs. As a result, a large and expensive burden is placed on the airline industry. By failing to adequately store a wheelchair in a cargo section of a jet, it is extremely common for the wheelchair to be damaged upon reaching its destination. In fact, the lack of a suitable container forces the airlines to spend at least $1.00 in repairs for every wheelchair carried. As wheelchairs become more expensive (wheelchairs range in price between $600.00 and $20,000.00) and more prevalent, the repair and administrative cost will become a more significant expense of the airlines bottom line




However, any container will not solve the above problem. Numerous factors must be taken into account in order to design one suitable for air travel including weight, uniformity, durability, ease to load and cost. In a typical example, a passenger reaches the airport less than one hour before take-off. In that one hour period, the wheelchair must be processed, packaged and loaded onto the plane. The baggage handlers for the airlines neither have the time, nor the training to disassemble the chair, rather they have just enough time to securely load it in the plane. As a result, certain traveling cases in the market place will not meet the demands of the airline industry. For example, a traveling case for a bicycle exists. However, the bicycle needs to be disassembled in order to be securely fastened in the container. That is, the handle bars, at least one wheel and the pedals are all removed. Thereafter, each piece is individually secured and mounted with foam, a process which can take in excess of one hour. Because the process is so labor intensive, the passenger loads and stores the bicycle prior to arrival at the airport. However, in the case of a disabled person, he uses the wheelchair to arrive at the airport. Therefore, he can not load it until he has checked-in.




Accordingly, it is desired to provide a container for a wheelchair that is light weight, durable and easy to load to enable the wheelchair to be shipped without damage.




SUMMARY OF THE INVENTION




Generally speaking, in accordance with the present invention, an apparatus for storing a wheelchair is provided. The apparatus includes a substantially rigid container dimensioned to receive a wheelchair including a first section and a second section. The first section includes at least a first end, a first wall extending from the first end, a second wall opposite the first wall, a first side panel extending from the first end positioned between the first and second walls and a second side panel opposite the first side panel. The second section includes a first end, a first wall extending from the first end, a second wall opposite the first wall, a first side panel extending from the first end and positioned between the first and second walls and a second side panel opposite the first side panel. The first section is releasably coupled to the second section to form an interior region for receiving a wheelchair.




Another apparatus for receiving a wheelchair is provided comprising a substantially rigid container dimensioned to receive a wheelchair including a first section and a second section. The first section includes at least a first end, a first wall extending from the first end, a second wall opposite the first wall, a first side panel extending from the first end and positioned between the first and second walls and a second side panel opposite the first side panel. The second section is substantially flat. The first section is releasably coupled to the second section to form an interior region for receiving a wheelchair.




Accordingly, it is an object of the invention to provide an improved container for securely storing a wheelchair during transportation.




Another object of the invention is to provide a container for a wheelchair that is lightweight, durable and easy to load to enable the wheelchair to be shipped without damage.




Still other objects and advantages of the invention will in part be obvious and in part be apparent from the specification.




The invention accordingly comprises the features of construction, combinations of elements, and arrangement of parts which will be exemplified in the constructions hereinafter set forth, and the scope of the invention will be indicated in the claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




In general, there are three distinct types of wheelchairs in the marketplace. All of which have different factors that must be taken into account in designing a proper container for air travel. While reference is being specially made for air travel, these containers may be used at home or for ship, train or truck cargo containers. Each model, that is, a folding wheelchair, a large fixed motorized wheelchair and a motorized scooter, will be described below in greater detail.




A folding wheelchair


10


as shown in

FIG. 1

weights approximately fifty (50) pounds. For travel, unlike the other two embodiments discussed below, wheelchair


10


may be folded. Referring to

FIGS. 1-8

, a container


12


for wheelchair


10


is disclosed. Container


12


is dimensioned so that its interior volume is slightly greater than the dimensions of wheelchair


10


. In this manner, wheelchair


10


fits within container


12


with minimum movement and at the same time minimizes material cost. In a preferred embodiment, container


12


is approximately 44×33×14 inches and weighs approximately 16 pounds.




Container


12


is typically made of plastic including polyethylene, polypropylene and ABS. It may be molded from using rotational molding, thermoforming or injection molding. The method of manufacturing depends on the cost and rigidity required of the particular design. The outer surface of container


12


is textured. In this manner, its surface is rough so that it does not slip out of the hands of the baggage handlers, while at the same time creates sufficient surface friction with the conveyor belt during loading. This is a critical feature in that large aircraft have steep conveyors for loading baggage. Therefore, in order to enable container


12


to reach the cargo hull, the surface of container


12


must be textured in order to remain on the conveyor.




Container


12


is comprised of two halves


14


and


16


, which are essentially mirror images of one another. Container


12


is reinforced by ridges


18


as best shown in FIG.


8


. Ridges


18


provide additional support for container


12


so that when a plurality of containers


12


are stacked one upon another during shipment, for example, the container can adequately support and handle the weight.




Half


14


is mounted to half


16


of container


12


via a hinge


22


. Hinge


22


can be a living hinge or piano hinge. In an alternative embodiment, hinge


22


can be replaced with additional latches


24


, described below in greater detail. In this manner, container


12


may be easily stacked along the airport terminal because halves


14


and


16


fit inside one another.




Half


14


is fastened to half


16


via latches


24


as best shown in FIG.


6


. As shown in

FIG. 6

, the latch mechanism is a strap of Velcro


7


which is fed through a belt hole and then strapped down to the other side of the Velcro


7


. Alternatively, a rotary action latch, a flexible draw latch or an overcenter latch may be used, as will be described in greater detail below with reference to FIG.


15


.




Handles


20


are provided about the exterior surface of container


12


as best shown in

FIGS. 9

,


10


and


11


. Handles


20


form a part of container


12


and are ergonomically designed so as to fit the hand or fingers of the baggage handlers. In this manner, two baggage handlers may walk along each side of container


12


and easily carry it. Alternatively, rollers


32


as shown in

FIG. 4

may be used so that container


12


may be rolled.




To use container


12


, wheelchair


10


is delivered to the baggage handlers at the airport. The chair is folded in half to a position as best shown in FIG.


2


. The container is opened about hinge


22


. Foam


30


, as best shown in

FIGS. 2 and 4

, is positioned on the inner portion of each half


14


and


16


. Foot rests


15


are first removed from wheelchair


10


. Thereafter, folded wheelchair


10


is placed within container


12


with the large wheels placed upon foam


30


. A strap


26


is then mounted up and over the frame to securely fasten wheelchair


10


to half


16


of container


12


. In the preferred embodiment, velcro straps are used, however, any type of buckle-strap arrangement, which provides the necessary security may be used. Footrests


15


are then mounted about a strap


28


within container


12


. Half


14


is then folded about hinge


22


toward half


16


. Thereafter, latches


24


are locked to securely attach half


14


to half


16


. In the preferred embodiment, four latches are used, but any number of latches may be used so long as they securely fasten the two halves to one another. Thereafter, a tag is placed on the outer surface of container


12


to appropriately label the container with the destination and passengers name.




Reference is now made to

FIGS. 12-15

, which describe an embodiment of a container for a large fixed motorized wheelchair


50


. Like numbers are used to denote like parts. Wheelchair


50


weighs approximately 250 pounds. Unlike folding wheelchair


10


above, wheelchair


50


cannot be folded for transport.




Wheelchair


50


is mounted in a container


52


. In a preferred embodiment, container


52


weighs approximately forty-five (45) pounds and includes bottom dimensions of approximately 49×40×32 inches and top dimensions of 49×40×30 inches. Container


52


includes two portions, a hood


54


and a base


56


. The inside volume of container


52


is slightly greater than that of wheelchair


50


. Container


52


is constructed by the same method and with the same materials as container


12


. Container


52


also includes the same textured surface and parts, including handles


20


, latches


24


, and ridges


18


as that described above with respect to container


12


.




Hood


54


includes an indent region


58


as best shown in

FIGS. 12 and 13

. Indent


58


reduces the overall amount of material required and forms a tight fit for wheelchair


50


within hood


54


. Base


56


is constructed of a rigid honeycomb construction. A honeycomb construction is well known in the art and requires the minimal amount of material, but provides for the rigidity of the part. Foam


30


is placed in various areas about hood


54


, and more particularly about the joy stick, microcomputer box and regulator. In particular, foam


30


is required about the sensitive electronic and mechanical components of wheelchair


50


, but may be placed anywhere the user feels appropriate.




To use container


52


, like the embodiment described above, wheelchair


50


is delivered to the baggage handlers. The battery of wheelchair


50


is disconnected and removed and transported separately due to federal regulation. At the destination, the battery is reinstalled and reconnected to wheelchair


50


. Footrests


15


are also removed. Wheelchair


50


is then pushed onto base


56


and strapped down thereon. In particular, a wheel strap


60


as best shown in

FIG. 13

is mounted about the axis of the wheels of wheelchair


50


. Thereafter, strap


64


may be used to mount wheelchair


50


on base


56


. Strap


64


is attached in a direction perpendicular to wheel strap


60


. A strap


62


is used to mount footrests


15


to base


56


. The number and positioning of straps


60


,


62


and


64


are only critical to the extent that it secures wheelchair


50


to base


56


. As a result, any number of straps, positioned in any particular position, may be used so long as wheelchair


50


does not rotate or shift during travel.




Thereafter, hood


54


is lifted and placed atop wheelchair


50


. Hood


54


is then latched to base


56


via latches


24


. In the preferred embodiment eight latches are used, two on each end and three on each side but any number of latches may be used so long as hood


54


is securely mounted to base


56


. As best shown in

FIG. 15

, latches


24


are recessed within container


52


. In this manner, container


52


does not have any extruding parts to catch on the conveyor belt, clothing or other bags. Based on the fact that latches


24


are flush to container


52


, container


52


may be loaded flush against other containers during transport. Therefore, no space is wasted and the container is less likely to move. Once hood


54


is securely latched to base


56


, container


52


is laid on its side for loading onto the airplane. If not rolled over, it will not fit in the standard cargo door of a plane from the conveyor belt. Because it is laid on its side, it is extremely important that wheelchair


50


be securely mounted to base


56


. Once in the plane, container


52


is rolled back onto base


56


for transport.




Reference is now made to

FIGS. 16-19

which describes and discloses a container


73


for a motorized scooter


70


. Motorized scooter


70


weights approximately 150 pounds. Like numbers are used to denote like parts in container


73


as discussed above with respect to containers


12


and


52


. In a preferred embodiment, container


73


weighs approximately 31 pounds and has the approximate dimensions of 49×35×25 inches. Scooter


70


includes a seat


71


and a steering column


72


. Prior to being inserted into container


73


, seat


71


is folded in the direction of arrow A to a position as denoted by the double dash lines in

FIGS. 16 and 18

. At the same time, steering column


72


is moved in the direction of arrow B to a position as shown in FIG.


18


. In this manner, the dimensions of scooter


70


have been minimized so as to securely fit within container


73


. The interior volume of container


73


is slightly greater than that of scooter


70


.




Container


73


includes a hood


74


and a base


76


with ridges


18


positioned thereon to provide further support. The construction and materials of hood


74


and


76


are identical to that described above with respect to containers


12


and


52


. Moreover, approximately eight latches


24


, three on each side and two on each end are provided to securely attach hood


74


to base


76


. Moreover, handles


20


are placed about hood


74


to enable baggage handlers and the like to carry container


73


to the plane. A strap


78


mounted to base


76


is used to securely fasten scooter


70


to base


76


. A strap


80


is used to further mount scooter


70


to base


76


and is fitted in a direction essentially perpendicular to strap


78


.




In an alternative embodiment, container


52


or


73


could be constructed in the form as shown in FIG.


20


. In

FIG. 20

, a hood


80


is formed with a first half


81


and a second half


83


. As shown with dashed lines, hood


80


can be formed in any shape. That is, it may be configured for a scooter


70


or alternatively for a wheelchair


50


. In this embodiment, handles, latches, ridges and materials are the same as those described above with respect to the other embodiments. To use the embodiment of

FIG. 20

, a wheelchair is rolled onto base


84


. Thereafter, a half


81


and a half


83


are moved towards base


84


and are fastened to one another by any type of latch disclosed herein. Thereafter, base


84


is securely fastened to halves


83


and


84


to protect a wheelchair during transport.




Reference is now made to

FIGS. 21 and 22

which describe a further embodiment of the invention. In this embodiment, a container


86


constructed of the same materials and including the same parts as described above with respect to the other embodiments includes a base


87


and a hood


88


. In this embodiment, a wheelchair is rolled onto a platform
