2. Description of the Related Art
The broad concept of a wheelchair loading and storage apparatus is known. These inventions usually involve a ramp or a lift. Some are suited for a wide variety of transporting vehicle while some are specifically intended for certain types of vehicles. Many of the existing inventions require extensive modification of the transporting vehicle to accommodate the wheelchair and the loading apparatus. Several of the existing inventions in this field require that the loading and storage apparatus take over functioning portions of the transporting vehicle and inhibit the use of those portions of the vehicle.
It is also known to construct a wheelchair loading and storage apparatus that uses a hoist to lift a wheelchair into a transporting vehicle. However, many of these hoist-utilizing apparatuses either load a wheelchair into the passenger compartment of the transporting vehicle, thereby requiring extensive modification of the passenger compartment of the transporting vehicle, or store the hoist in a location in which the hoist and/or the wheelchair is exposed to the elements during transportation.
It is also known to construct a wheelchair loading and storage apparatus which stores a wheelchair in a weather-resistant enclosure. However, most of these existing inventions with weather-resistant enclosures use the existing weather-resistant enclosures of the transporting vehicle, such as the passenger compartment. In such instances, extensive modification of the transporting vehicle is required to accommodate the wheelchair and the loading apparatus. Other existing inventions with weather-resistant enclosures substantially inhibit the use of portions of the vehicle. For example, inventions exist which store a wheelchair and its loading apparatus in the bed of a pick-up and use a camper-style enclosure to protect the wheelchair and the apparatus from exposure to the elements; however, this invention substantially inhibits the use of the remaining portions of the pick-up-truck bed from uses other than those of a camper-enclosed bed, and items too large to fit within the camper may not be transported while transporting a wheelchair.
It is also known to construct a wheelchair loading and storage apparatus specifically for pick-up trucks. However, many of the existing inventions do not protect the wheelchair from the elements once the wheelchair is loaded into the pick-up truck bed. Additionally, existing wheelchair loading and storage apparatus for pick-up trucks do not protect the loading apparatus itself from exposure to weather in the bed of the pick-up truck. The existing wheelchair loading and storage apparatus for a pick-up trucks which do protect the wheelchair and the apparatus itself from exposure to the elements require extensive modification of the vehicle or substantially inhibit the use of the pick-up-truck bed for its ordinary uses.
SUMMARY OF THE INVENTION
The broad embodiments of the present invention relates to improvements of an apparatus for loading a wheelchair into a vehicle which automatically stores the wheelchair within an enclosure that protects the wheelchair and the mechanisms of the apparatus from exposure to weather during transportation. In particular, the Wheelchair Transportation Loading and Storage Apparatus would primarily be used to automatically load into and store a wheelchair within an enclosure which protects the wheelchair and the loading apparatus' mechanisms from weather and which is mounted in a portion of a pickup truck bed to allow for substantial use of the pickup bed for other purposes, such as the transportation and storage of tools and materials.
In the most preferred embodiments, the Wheelchair Transportation Loading and Storage Apparatus comprises a hoist and a weather-resistant enclosure. In more detail, the hoist comprises a mast, a lifting arm, and an extendable strap, and is capable of lifting a wheelchair from a position substantially near the passenger compartment, over the sidewall of the pickup truck bed and into the enclosure, allowing utilization of the Wheelchair Transportation Loading and Storage Apparatus by the driver of the pick-up-truck-type vehicle. The mast is cable of telescoping from a stowed position which fits within the enclosure to deployed position which extends above the sidewall of the pickup truck bed. The lifting arm is mounted on the mast and comprises a fore arm and an aft arm, which are connected by a hinge and actuated by a piston. The lifting arm is capable of transitioning from a folded position that fits within the enclosure to a deployed position that extends the end of lifting arm to a location substantially near the passenger compartment of the pickup truck, allowing utilization of the Wheelchair Transportation Loading and Storage Apparatus by the driver of the pick-up-truck-type vehicle. The extendable strap comprises a strap and a wench. The strap is connected to the wench and extends from the end of the lifting arm to connect to a wheelchair when it is in a location substantially near the passenger compartment of the pickup truck and below the end of the lifting arm in its deployed position. The wench uses the strap to lift the connected wheelchair to a position substantially near the end o f the lift arm, so that the lift arm may swing the wheel chair over the sidewall of the pickup truck to a location above the enclosure where it is then lowered into the enclosure. The enclosure comprises a weather-resistant shell and a weather-resistant cover that may be remotely opened and closed. The enclosure provides sufficient interior space to store a wheelchair and the mechanisms and electronics of the apparatus. The cover is capable of closing the enclosure and sealing the interior to sufficiently resist its exposure to external weather conditions. The Wheelchair Transportation Loading and Storage Apparatus allows a wheelchair to be transported in poor weather conditions without exposing delicate parts of the wheelchair to elements which can cause corrosion and damage. Furthermore, the Wheelchair Transportation Loading and Storage Apparatus enables a wheelchair user, including the driver of the pick-up-truck-type vehicle, to transfer to the passenger compartment or driver's seat of a pickup truck and independently load and stow the wheelchair into a weather-resistant enclosure. The enclosure is small enough to permit the pickup bed to be used for its intended purpose, such as storing and transporting tools and/or materials. Additionally, when closed, the apparatus has the appearance of a standard pickup truck bed tool box, concealing the wheelchair loading and storage cap ability of the vehicle.

The advantages of the present invention include, without limitation, that it provides a means for loading a wheelchair into a protective cover mounted in the bed of a pick-up-type vehicle and prevents exposing the wheelchair and the mechanisms and electronics of the Wheelchair Transportation Loading and Storage Apparatus to weather and the elements while the wheelchair is within the protective cover during transportation. The Wheelchair Transportation Loading and Storage Apparatus is capable of lifting a wheelchair from a position substantially near the passenger compartment of a pick-up-truck type vehicle into an enclosure mounted in the pick-up-truck-type vehicle's bed, allowing the driver of the pick-up-truck-type vehicle to utilize the Wheelchair Transportation Loading and Storage Apparatus. The enclosure comprises a weather-resistant shell and a weather-resistant cover that may be remotely opened and closed, which does not substantially inhibit the use of the pickup truck bed and which does not require extensive modification of the transporting pick-up-truck-type vehicle. The Wheelchair Transportation Loading and Storage Apparatus allows a wheelchair to be transported in poor weather conditions without exposing delicate parts of the wheelchair to elements, which can cause corrosion and damage, during transportation. Furthermore, the Wheelchair Transportation Loading and Storage Apparatus enables a wheelchair user, including the driver of the pick-up-truck-type vehicle, to transition himself or herself to the passenger compartment or driver's seat of a pick-up-truck-type vehicle and independently load and stow the wheelchair into a weather-resistant enclosure without the assistance of others. The enclosure is small enough to permit the pick-up-truck-type vehicle bed to be substantially used for its intended purpose, such as storing and transporting tools and/or materials. Additionally, when closed, the Wheelchair Transportation Loading and Storage Apparatus has the appearance of a standard pick-up truck bed toolbox, concealing the wheelchair loading and storage capability of the vehicle.
In broad embodiment, the present invention is an improvement of an apparatus for loading a wheelchair into a vehicle which automatically stores the wheelchair within an enclosure that protects the wheelchair and the mechanisms of the apparatus from exposure to weather during transportation. The Wheelchair Transportation Loading and Storage Apparatus automatically loads into and stores a wheelchair within a secure enclosure which protects the wheelchair and the loading apparatus' mechanisms from weather and expos we to the elements and which is mounted in a portion of a pickup truck bed to allow for substantial use of the pickup bed for other purposes, such as the transportation and storage of tools and materials.
While the foregoing written description of the invention enables one of ordinary skill to make and use what is considered presently to be the best mode thereof, those of ordinary skill will understand and appreciate the existence of variations, combinations, and equivalents of the specific embodiment, method, and examples herein. The invention should therefore not be limited by the above described embodiments, methods, and examples, but by all embodiments and methods that are within the scope and spirit of the invention as claimed.
