       BACKGROUND OF INVENTION 
       [0004]    Field of the Invention/Technical Field 
         [0005]    The disclosure herein relates to the specific area of hoisting apparatuses, and more specifically, the technical field of portable lifting devices, and lastly, the technical area of wheelchair and scooter utilities. 
         [0006]    Related Art of the Invention 
         [0007]    In general, people have previously attempted to have a compact means to lift objects with an apparatus. The U.S. patent publication 2009/0152227 (2009/0152227) discloses a method and apparatus to lift payloads onto or into a vehicle. However, it does not disclose a lightweight foldable construction nor, does 2009/0152227 disclose a portable stabilizing base. The U.S. patent publication U.S. Pat. No. 5,388,289 (U.S. Pat. No. 5,388,289) discloses a knockdown, portable combination wheelchair and lift which is readily assembled and disassembled, thereby enabling stowage and transport when not in use. However, it does not disclose a separate entity, that is a portable lifting apparatus apart from the wheelchair itself. Nor, does it disclose a sturdy means for attaching a liftable object to the lifting apparatus. Nor, does it disclose an ability to have multiple objects, not only wheelchairs, be lifted by the device. The U.S. patent publication U.S. Pat. No. 6,007,289 (U.S. Pat. No. 6,007,289) discloses a lift mounted to the rear portion of a vehicle to selectively store and remove a personal mobility vehicle in and from the trunk of the vehicle. However, it does not disclose a portable base, allowing lifting of a portable mobility vehicle without being attached to a vehicle nor, does U.S. Pat. No. 6,007,289 disclose a motor not present on hoist, but on the portable mobility vehicle itself. 
       GENERAL SUMMARY OF THE INVENTION 
       [0008]    In general, the invention solves numerous problems as highlighted in the background. For example, it allows one to easily move a modified heavy electric wheelchair to and from a vehicle. Ideally it is composed of a lightweight material and will allow one the ability to use any vehicle in order to transport their electric chair. This is accomplished by a unique arrangement of specific elements, including a foldable base, a hoisting arm and a power supply and motor present on the chair itself. This allows one to 1) unfold the portable lift 2) attach the portable lift to the wheelchair 3) Use a means for activating the wheelchair lift motor for raising/lowering of the hoisting arm. 
         [0009]    It is an object of the invention to provide a lighter lift for electric wheelchairs. Yet another object of the invention is to provide an alternative to a permanent lift mounted to a car. Yet another object of the invention is to provide a way for disabled individuals to use multiple non-lift mounted vehicles to pursue their activities. Yet another object of the invention is to pick up the chair from a lower vertex in order to add space and minimize height requirements. Yet another object of the invention is to keep the chair stable in a level position during lift and transportation. Yet another object of the invention is to enable people to take the device on an airplane, train or other public transportation and store it in an overhead compartment. An additional object of the invention is to minimize the occupied volume (via folding) that would otherwise be taken up with a portable lifting device.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0188]    A general method for using the invention preferably involve several steps: (i) To begin, a person acquires the portable lifting apparatus. (ii) Next, a person stores the lifting apparatus in its folded state. (iii) Then, after detecting the need for use of the apparatus, the person transports the apparatus to the an area near the device to be lifted. (iv) Next, a person manipulates the invention into the unfolded state. (v) Then, a person positions the lifting apparatus so that it operably interacts with the object to be lifted. (vi) Next, a motor (present either on the lifting apparatus or device to be lifted; or manual manipulation) raises the object into suspension. (vii) Next, one or more articulations, combined with movements of the base, maneuver the object lifted. (viii) Next, upon desire to detach the object, the object is positioned near its target area. (ix) Then, a motor (present either on the lifting apparatus or device to be lifted; or manual manipulation) lowers the object near the target area. (x) Then, once stable, the portable apparatus detaches from the object. (xi) And last, a person may choose to return the portable lifting apparatus to its folded state for storage. The above method is herein identified as method  500  and while these steps are depicted in an order, it is thought that these steps may be performed in one or more alternative orders. 
         [0189]    The invention has some elements that are commonly known, however their use and relationships to the novel components and steps of the invention render them applicable herein. In order to highlight the roles in the specification, they are subsequently explained here: A liftable object  1  comprises an object that is heavy enough for the operator of the lifting apparatus, that it would be desirable to not lift the object manually. In some embodiments, one may reason that examples of an liftable object  1  may include a powered wheel chair, scooters, coolers, groceries, a toolbox, or lawn equipment. An electrical power source  2  comprises a device that delivers electrical energy to perform work. In some embodiments, one may reason that examples of an electrical power source  2  may include, a battery, AC power, DC power, solar power, or wind power. The electrical control source  3  comprises a device or system that controls its operation. In some embodiments, one may reason that examples of an electrical control source  3  may include a wired hand controller, a wireless remote controller, a smartphone control, a wifi control, or a bluetooth control. In some embodiments, it is reasonable to contemplate that examples of a belt  4  may include belt-like devices, for example, chains. In some embodiments, one may reason that examples of a motor  5  may include an electrical motor, a compressed air motor, a drill, or hydraulics. 
         [0190]    Overall the invention can be viewed as several interactive sub-items which grossly include; a base, a lifting assembly  6 , and a chair motor assembly  7 . In a preferred embodiment, the base is preferably situated beneath the lifting assembly  6 . The base can also be collapsed on itself in the folded state, and immediately above a stabilizing surface (such as the ground) in the active state. The base is designed to both 1) support the lifting assembly  6  and to 2) allow mobility for moving an object that is being lifted. In the main embodiment of the invention, the base is chiefly contemplated to be created from aluminum but other embodiments may be composed of some of the following materials: steel, composite, or carbon-fiber. In the preferred embodiment, the base includes two sub-items, the base support piece  8 , and the folding mechanism  9 , respectively. 
         [0191]    Examples of a base support piece  8  may 1) include a removable platform, that allows one to lift alternate things besides a chair, 2) may include motorized wheels and perhaps remote guidance of the base, so that one may not move it manually, or 3) may include means for steering the base, then locking the base, and which provides a stable platform (with rails) for moving the chair in a specific direction (without using the wheels in the base). In some embodiments, one may reason that if the base support piece  8  is absent, than a tripod assembly may suffice for support. The base support piece  8  preferably comprises, a base lateral arm  10 , a base forward arm  11 , a base forward lateral arm connection region  12 , and a ground mobility mechanism  13 . 
         [0192]    In a preferred embodiment, the base lateral arm  10  is preferably positioned near the lifting assembly  6  and perpendicular to the base forward arm  11 . The base lateral arm  10  has several aims which are as follows: First, the purpose of the base lateral arm  10  is that it connects the base forward arm  11  and the lifting mechanism. Next, it provides width and stability to the lift. Finally, it aims to form an area that allows folding of the arm assembly for transport. In some embodiments, one may reason that an example of a base lateral arm  10 , may be a telescoping lateral base arms. Further, the base lateral arm  10  preferably comprises a base arm connector region  14 . 
         [0193]    The base arm connector region  14  comprises the medial end of the base arm connector region  14 . The base arm connector region  14  is designed to both 1) bind to the base lateral arm connector  16  and to 2) provides a pivot region, for folding and unfolding. Further, the base arm connector region  14  preferably comprises an additional sub-component herein termed the pivot exterior buttressing surface which comprises the top surface of the arm and interacts with the plate on the connecting region. One goal of the pivot exterior buttressing surface  17  is to provide a support surface, so that when the base is in the open position it can bear the load of both the lift and the chair. 
         [0194]    In the preferred embodiment, the base forward arm  11  is preferably positioned perpendicular to the base lateral arm  10  and beneath the lifting assembly  6 . The base forward arm  11  has several intents which are as follows: First, the purpose of the base forward arm  11  is that it provide stability. Next, another purpose is to have a length long enough to provide a cantilever balance, allowing it to fit underneath raised structures such as automobiles. In some embodiments, one may reason that an example of a base forward arm  11  may include telescoping forward arms. In addition, the base forward arm  11  preferably comprises the front mount  18 . 
         [0195]    The front mount  18  comprises a mechanism for moving the base along a surface upon which it rests. It is preferably positioned on the apical end of the forward arm. It has several intents which are as follows: First, the purpose of the front mount  18  is to provide maneuverability. Next, another purpose is to bear the load of the chair and lift. Lastly, the contact surface points should have a soft surface (such as rubber), so that the metal of the base forward arm  19  does not scrape a floor when collapsed. In some embodiments, it is reasonable to contemplate that an example of a front mount  18  may include a ball roller, sliders, or motor driven wheels. 
         [0196]    The base forward lateral arm connection region  12  is preferably positioned in between the base lateral arm  10  and base forward arm  11 . One goal of the base forward lateral arm connection region  12  is to bind the base lateral arm  10  and base forward arm  11 . In some embodiments, an example of a base forward lateral arm connection region  12  may include a foldable joint so that the forward legs and lateral legs can collapse. 
         [0197]    The ground mobility mechanism  13  is positioned between the forward and lateral arms and comprises a structure that has both a mobility mechanism and an unfolding/folding mechanisms. In some embodiments, one may reason that if the ground mobility mechanism  13  is absent, than there may be a fixed support, such that no wheels or casters exist and a pivot motion of the arms will allow for swinging in order to enhance mobility. The ground mobility mechanism  13  preferably comprises a rear mount  20 . 
         [0198]    The rear mount is a general term for the components that bind together the base lateral arm and base forward arm, and the lift, to the mobility mechanisms that allow its operation. The rear mount  20  preferably includes a corner caster mount region  21 , a corner caster mount region rounded edge  22 , an unfolding roller  23 , a corner support latch  24 , and a rear mount wheel  25 . 
         [0199]    The corner caster mount region  21  comprises the region that serves as a substrate for connecting the various components together of the rear mount  20 . The corner caster mount region  21  is preferably positioned around the joint of the lateral and forward arms and encompasses them. One goal of the corner caster mount region  21  is to bind to the base forward arm  11  and base lateral arm  10 . Further, the corner caster mount region  21  preferably comprises a corner caster mount region tapered edge  26 , which prevents a sharp edge from interacting with the user. 
         [0200]    The corner caster mount region rounded edge  22  is preferably positioned outside and wrapping the forward arm. The corner caster mount region rounded edge  22  is designed to both 1) make it smoother so that it does not interact with the user and to 2) adds strength to the rear mount. 
         [0201]    In the preferred embodiment, the unfolding roller  23  is preferably positioned behind the rear mount wheel  25  and (on the ground) when invention is in the process of being folded. The unfolding roller  23  has several aims which are as follows: First, the unfolding roller  23  allows the legs to expand without the user having to bend over. It also keeps metal from the arms from scraping on the ground. Lastly, its placement and motion, allow it to be “auto-unfolding” to a user. Alternative examples of an unfolding roller  23  might be, a ball roller or sliders. 
         [0202]    The corner support latch  24  is preferably positioned on the inside of the forward arm. The corner support latch  24  is designed to both 1) provide structural support for the corner and to 2) provide latch when in folded position. If corner support latch  24  is absent, one can contemplate that the forward arms may attach to one another. Or perhaps, that the lateral arms may attach to one another. Or perhaps there is another mechanism that may mediate a connection between the forward arms and/or lateral arms. In the preferred embodiment, the corner support latch  24  preferably comprises a corner support catch  27 , and a corner support glide path  28 , respectively. 
         [0203]    The corner support catch  27  is preferably positioned opposite the glide path. It is designed to both 1) lock to the latch handles  29  and to 2) bind the base lateral arm  10  and base forward arm  11 . In some embodiments, an example of a corner support catch  27  may be a magnetic catch and the like. In a preferred embodiment, the corner support catch  27  preferably comprises a corner support aperture  30 , and a corner support entry path  31 , respectively. One goal of the corner support aperture  30  is to encompass the latch handles  29  so that when folded it will catch and lock in the folded position so that it can be lifted. 
         [0204]    The corner support entry path  31  is preferably positioned before the corner support aperture  30 . One goal of the corner support entry path  31  is to guide the latch handles  29  upon folding so that they enter the corner support aperture  32 . In turn, the corner support glide path  28  is preferably positioned on the edge of the latch. It helps when folding the invention, such that the latch handles  29  will be guided over the corner support catch  33  and it can be put into a locking position. 
         [0205]    In a preferred embodiment, the rear mount wheel  25  is preferably situated forward of the unfolding roller  23 , where it touches the ground (in the unfolded state), and is present on the bottom side of the arms. The rear mount wheel  25  has several intents which are as follows: First, the purpose of the rear mount wheel  25  is to roll the lift when in use. Next, it aids the unfolding roller  23  in unfolding the invention. Next, another purpose is to maneuver and steer the lift with the help of the front mount  18 , while the chair is in the lifted state. Lastly, it should be sturdy enough to bear the weight of the chair and lift. In some embodiments, it is reasonable to contemplate that an example of a rear mount wheel  25  may also be a ball roller, sliders, or motor driven wheels. 
         [0206]    The folding mechanism  9  comprises a physical means to connect the different arm types and also provide a mechanism to fold the device. In the preferred embodiment, it is preferably positioned between the lateral arms and below the lifting assembly. In some embodiments, examples of a folding mechanism  9  may be a joint folding mechanism that does not have base lateral arm connector  16 , u-joints, ball joints, ball joint assembly with folding tripod legs, or u-joint assembly with folding tripod legs. 
         [0207]    It is also not necessary that the folding mechanism  9  be used. In some embodiments, one may reason that if the folding mechanism  9  is absent, than there may be solid single lateral arm and folding may occur in the arms, with our without telescoping. In other instances, if folding mechanism  9  is absent than arms of the base may be disconnectable, for storage and or transportation. The folding mechanism  9  preferably comprises a base arm connector  15  to connect the arm to the base via the lower support arm  43 . In turn, the base arm connector  15  preferably comprises a base lateral arm connector  16 , and a lower arm mount  35 , respectively. 
         [0208]    The base lateral arm connector  16  has several intents which are as follows: First, the purpose of the base lateral arm connector  16  is that it is a means by which the base support pieces  8  bind to each other. Next, another purpose is to allow a pivot for folding and unfolding. Finally, it aims to provide load bearing support for the invention. 
         [0209]    In some embodiments, one may reason that if the base lateral arm connector  16  is absent, than there may be a direct connection between the two lateral arms and it could be folded on a joint. In the preferred embodiment, the base lateral arm connector  16  preferably comprises a base lateral arm pivot region  36 , and a middle no load mounting surface  37 , respectively. One goal of the base lateral arm pivot region  36  is to have a convenient way to fold and unfold the device. The middle no load mounting surface  37  is designed to both 1) act as a support when there is no load and to 2) function as a stop for the lower support arm  43  when there is no load. 
         [0210]    The base lateral arm pivot region  36  preferably comprises a lateral pivot aperture  38 , a ventral pivot aperture  39 , a connector interior buttress surface  40 , and a connector interior buttress plate  41 . One goal of the lateral pivot aperture  38  is to bind to the lateral arm via a pin and allow rotation when folding and unfolding in concert with the ventral pivot aperture. One goal of the ventral pivot aperture  39  is to bind to the lateral arm via a pin and allow rotation when folding.

In some embodiments, one may reason that an example of a chain  132  may be instead replaced with helical gears. One goal of the belt holder  127  is to translate motor movement into winding or unwinding of the belt. In the preferred embodiment, the belt holder  127  preferably comprises a belt sprocket  133 , and a belt spool  134 , respectively. These translate the movement of the motor into rotation of the belt roller. Instead of a belt sprocket  133  alternative means could be helical gears, direct gears, or worm gears. One goal of the belt aperture  59  is to have an opening in the housing that the belt can pass through. One goal of the positioning roller is to protect the belt from being destroyed by the housing. 
         [0257]    The belt  4  is generally contemplated to be created from nylon but in some embodiments is reasonable to imagine that that the belt  4  could also be created from carbon reinforced thread or synthetic or natural material. When using the invention, it is thought that an example of a belt  4  might be a chain or also a rope. 
         [0258]    One goal of the stem  128  is to have a support means to operably connect to the receiver collar  135  on the lifting arm. When using the invention, it is thought that an example of a stem  128  might be an insertion stem, which is operated via horizontal attachment rather than vertical attachment or perhaps also a quick connection (ball; similar to a power washer). 
         [0259]    It will be appreciated by those skilled in the art that changes could be made to the embodiments described herein without departing from the broad inventive concept thereof. It is understood, therefore, that this invention is not limited to the particular embodiments disclosed, but it is intended to cover modifications within the spirit and scope of the present invention as defined by the appended claims.
