The base plate may be adapted for mounting on a base of the trunk of the vehicle. The arm assembly may be extending outward from the vertical support post for attachment to the wheelchair or the like. The base plate is designed and arranged to facilitate side movement of the vertical support post after the wheelchair has been lifted, in order to allow for hoisting of the suspended wheelchair from the ground to the trunk of the vehicle and vice-versa, as required by the user. It may be understood that the vehicle 12 being employed may be any suitable vehicle, preferably a pickup truck or a vehicle with large trunk or boot space for easy installation of the lift mechanism 10 and further storage of the wheelchair therein.

(9) FIG. 2 illustrates an exploded diagrammatic view of the lifting assembly 100. In particular, FIG. 2 shows individual components of the lifting assembly 100 for better understanding of the arrangement and functioning thereof. As illustrated, the lifting assembly 100 includes a supporting structure 102 which is designed in the shape of a cross member. For example, the supporting structure 102 may be a cloth structure made of two intersecting pieces of strips of cloth crossing each other. The supporting structure 102 may be made of a strong and flexible material, like reinforced cotton fibers (like steel-cotton fabric) or plastics (like polyethylene or polypropylene) or even metallic sheets (like sheets made of aluminum). It may be understood that the two strips of the supporting structure 102 may be joined together by any suitable means. For instance, the strips being pieces of cloth could be stitched together. In other example, the strips being plastic or metallic pieces could be welded together.

(10) Further, as illustrated, the lifting assembly 100 includes a connecting arrangement 104 attached to the supporting structure 102. In one example, the connecting arrangement 104 may also be in the form of a cross member extending with shape of the supporting structure 102. The connecting arrangement 104 may be made of a strong material, such as stainless steel, aluminum and the like. Further, the connecting arrangement 104 may be attached to the supporting structure 102 using any suitable method, such as, welding, use of fastening members, adhesives, etc. without any limitations. As may be seen from FIG. 2, the connecting arrangement 104 may include apertures 106 formed at each of its four ends to allow for engagement of some other member therewith (as discussed in the subsequent paragraphs).

(11) As illustrated in FIGS. 1 and 2, the lifting assembly 100 includes two or more cables 108 which are coupled from one of their ends with the connecting arrangement 104. Specifically, the cables 108 may include quick-release snap hooks 110 fixed thereto at their said ends. These snap hooks 110 may engage with the opposing apertures 106 of the connecting arrangement 104 to be removably coupled therewith. Such use of snap hooks for engagement may be easily contemplated and have not been described in further detail herein. Therefore, the cables 108 may be used to suspend the supporting structure 102. It may be understood that the supporting structure 102, when in suspended form, may provide shape of a sling arrangement which can be used to support a suitable item therein.

(12) Further, in accordance with present embodiments, the lifting assembly 100 includes at least one shackle 112 which is adapted to be fixedly attached with the lift mechanism 10. It may be contemplated that the shackle 112 may be attached with the lift mechanism 10 by means of screws or some other suitable fastening means known in the art. Moreover, the shackle 112 may be coupled with the cables 108 at their other ends (opposite to the ones coupled with the connecting arrangement 104). Thus, the shackle 112 may mechanically couple, and helps to bear and transfer weight of the supporting structure 102, to the lift mechanism 10. In one example, the shackle 112 may be designed and reinforced for supporting weights up to 8-10 tons, as may be required for the purpose of lifting a wheelchair or the like of the present disclosure. Such shackles are well known in the art and widely available in the markets for use.

(13) With reference to FIGS. 1 and 2, in combination, it may be contemplated that the supporting structure 102 of the lifting assembly 100 may be able to support a desired item therein, and further allow to hoist the supported item by means of the lift mechanism 10, as may be desired by the user. The supporting structure 102 being a cross-member form a sling arrangement during suspension thereof by cables 108, and thus may be able to wrap around most of the common items, including a wheelchair with ease. Thus, the lifting assembly 100 could easily be able to provide lift support and transfer the wheelchair from one location to another utilizing the power of the lift mechanism 10. FIG. 3 depicts the lifting assembly 100 of the present disclosure being implemented for lifting a wheelchair 14. It may be understood that the wheelchair 14 may be lifted from the ground and hoisted to be stowed in the trunk of the vehicle 12 at the beginning of a journey; and subsequently may be removed from the trunk, hoisted and placed back on the ground for use by the user.
