DETAILED DESCRIPTION

(16) Reference is now made to the drawings for an illustration of the concepts of the present invention. FIG. 1 in particular is an exploded perspective view of an entire assembly of all components used in constructing the final lift. Because many of the main components are presently known they will not be described herein in detail. The present description is aimed at certain modifications that enable an easier transport of the bundle of components from an assembly site where the components are prepared for shipping to a set-up or re-assembly site where the lift is set up for final use. The term used herein for the assembly of all components is bundle or package.

(17) The main components shown in FIG. 1 include four lift columns 10, cross beams 12 and runways 20. Mechanisms are associated with these components that control the lift and which may include mechanical components such as cabling and electrical components. Also included are the cross beams 12 that interconnect pairs of lift columns 10 and that connect with the parallel runways used in lifting the vehicle. The vehicle is meant to be driven onto the runways and then lifted via actions at the lift columns, which in turn lift the respective cross beams and runways in unison.

(18) As indicated previously FIG. 1 shows the complete lift assembly. FIGS. 2-11 describe one embodiment of the present invention. FIGS. 12 and 13 are meant to illustrate how certain components are packaged to have a shorter length. This makes the transportation of the package or bundle far easier without requiring complex special equipment such as a fork lift. FIGS. 13 and 14 describe another embodiment of the present invention regarding a particular construction of the runways that is considered as stronger in its structure.

(19) With regard to the embodiment of the present invention illustrated in FIGS. 2-11, it is noted that the modular automobile lift can be arranged in a compact bundle for the purpose of transportation of the modular automotive lift to a setup or reassembly site. In this regard, FIG. 11 at 40 shows the substantial length of the bundle that has been previously required, thus requiring the use of a piece of special equipment such as a forklift. On the other hand, reference may be made to FIG. 12 that shows two shorter length bundles 42A, 42B. Because of the shorter length of these bundles, the assembled bundle or package can be delivered more easily such as by using a conventional pickup truck or other vehicle with a lift gate. The modular automobile lift is comprised of several components as illustrated in FIG. 1 and includes a pair of separate runways meant ultimately for the support of a vehicle, and a pair of cross beams meant ultimately for the lifting of the pair of runways by means of the lift columns 10.

(20) Reference may now be made to FIGS. 2 and 3 which illustrates that each runway 20 is constructed and arranged in separate runway segments 20A, 20B. FIGS. 2 and 3 illustrate these segments 20A, 20B as being connected together at an initial assembly site by means of the mounting members 22. The segments 20A, 20B may be originally constructed as separate segments or an existing runway may be cut in half to form the separate runway segments as illustrated. Thus, the runway segments are essentially reassembled at the final use site by securing the separate runway segments in series by means of a mounting member.

(21) As illustrated in FIG. 3, these mounting members may be considered as comprised of a mounting member 22A and a mounting member 22B that are of similar construction. However, the mounting member 22A is provided with a lip 25. This lip 25 is also shown in FIG. 1 in the mounting members. Each mounting member is illustrated as formed basically as a U-shaped channel with the opening of the channel resting against respective sides of the runway segments. It is preferred that the lip 25 on the respective mounting members 22A be in a facing relationship. This lip 25 associated with each runway can then be used as a mounting surface such as a surface for mounting a tool box arrangement. FIGS. 2 and 3 also illustrate fasteners at 24 which may be comprised of a bolt, nut, regular washer and lock washer. FIG. 2 in particular shows two of the mounting members 22 secured in place as well as the other pair of mounting members exploded away from the runway. Also illustrated in FIG. 2 is a cutout at 23. This cutout is in a further lip 27. Each of the mounting members 22 is meant to fit within the cutout or recess 23.

(22) Reference is now made to FIGS. 5 and 6 which show an underside to the segment 20A, 20B. Also illustrated are the mounting members 22 one of which is provided with the lip 25. FIGS. 4 and 5 also illustrate fasteners at 24 which may including a bolt, nut, regular washer and lock washer. FIG. 4 also illustrates the aforementioned cutout at 23. FIG. 5 illustrates the mounting members 22 as in position. FIG. 6 is a further fragmentary perspective view on the opposed side of the runway to that shown in FIG. 3 and also illustrating the lip at 25. The lip 25 is in a position facing the lip 25 of the opposed runway mounting member.

(23) The other main component that is modified in accordance with the present invention is the cross beam 12 illustrated in FIG. 1. As illustrated in FIGS. 7-10, the cross beam is cut at about its middle location (or can be originally formed in segments) and is thus constructed and arranged in separate cross beam segments 30A, 30B that are meant to be connected together at the final assembly site. The cross beam is finally formed at the final assembly site by securing the separate cross beam segments 30A, 30B in series by means of the opposed position connector members 32. Connector member 32 may be a solid rectangular metal piece having holes for receiving fasteners illustrated at 34 in FIG. 8. Of course, there are several fasteners that are used disposed at intervals along each of the cross beam segments. These fasteners may be in the form of a bolt, nut, regular washer and lockwasher. As illustrated in the cross-sectional view of FIG. 10, one of the fasteners 34 passes through opposed walls defining the cross beam segment and through the connector member 32. As also illustrated in FIGS. 8 and 9, the cross beam segments 30A, 30B are both hollow so as to receive the inner disposed connector member 32. In an alternate embodiment of the present invention, in place of the connector member 32 as illustrated, a pair of side plates may be provided on opposite sides of the respective cross beam segments.

(24) Reference is also now made to a different version of the present invention illustrated in FIGS. 13 and 14. This provides sidewalls 52 and 54 that are in the form of a truss. This embodiment also employs opposed mounting members 56 and uses fasteners 58 as illustrated in FIG. 14. The mounting members 56 interconnect runway segments 50A and 50B.

(25) In accordance with other features of the present invention each separate runway segment extends longitudinally having a length greater than its width; the number of separate runway segments is at least two and may comprises greater than two thus shortening the bundle even further; the at least two separate runway segments may be of substantially the same length; the mounting member comprises a channel member; including fasteners for securing the channel member between adjacently disposed runway segments so that the runway segments form a continuous runway without any gap between the runway segments; wherein each channel member is disposed at a side of the runway segment; one on each side of the assembled runway segments; further including a connector member; wherein each cross beam constructed and arranged in separate cross beam segments and meant to be connected together at the lift assembly site; and wherein each cross beam is formed at the lift assembly site by securing the separate cross beam segments in series by means of the connector member; and including fasteners for securing the connector member between adjacently disposed cross beam segments so that the cross beam segments form a continuous cross beam without any gap between the cross beam segments.

(26) In accordance with the present invention a further feature is a method of constructing a modular automobile lift by initially arranging components of the automobile lift in a bundle ready for transportation, providing as part of the bundle a pair of runways with each runway constructed and arranged in separate runway segments, providing a mounting member, transporting the bundle to a lift assembly site, and re-assembling the separate runway segments at the lift assembly site by securing the separate runway segments in series by means of the mounting member.

(27) Other features include providing fasteners as part of the bundle and for securing together the separate runway segments; providing fasteners as part of the bundle for securing the mounting member between adjacently disposed runway segments so that the runway segments form a continuous runway without any gap between the runway segments; providing each cross beam constructed and arranged in separate cross beam segments and a connector member; and providing the connector member to connect together the separate cross beam segments at the lift re-assembly site.

(28) A further feature of the present invention is a modular automobile lift bundle that is particularly formed in a length for ready transportation of the modular automobile lift from a bundling site to a lift re-assembly site. The modular automobile lift bundle includes a pair of separate runways meant ultimately for the support of an automobile and a pair of cross beams meant ultimately for the lifting of the pair of runways by means of lift columns. Each runway is constructed and arranged in separate runway segments and meant to be connected together at the lift assembly site, a mounting member, and each runway being formed at the lift re-assembly site by securing the separate runway segments in series by means of the mounting member. The lift bundle also includes a connector member and wherein each cross beam is constructed and arranged in separate cross beam segments and meant to be connected together at the lift assembly site. Fasteners are provided for securing the mounting member between adjacently disposed runway segments so that the runway segments form a continuous runway without any gap between the runway segments, along with fasteners for securing the connector member between adjacently disposed cross beam segments so that the cross beam segments form a continuous cross beam without any gap between the cross beam segments.
