DETAILED DESCRIPTION
(34) Transport, assembly, and use of an example device or system in accordance with aspects of the present invention will now be further described.
(35) FIG. 1 is a Photostat showing various example components for an unassembled device or system in accordance with aspects of the present disclosure.
(36) FIG. 2 is a Photostat showing an example fixed upright portion 9 for a device or system in accordance with aspects of the present disclosure in process. FIG. 3 is a Photostat showing the example fixed upright portion 9 of FIG. 2 in process of being attached to a mounting plate 2. The fixed upright portion 9 may include, for example, an end flange portion 9a (a welded or attached approximately 4 by 6 plate) having holes or openings therein, and/or other features, for attaching the fixed upright portion 9 to the mounting plate 2, such as via one or more bolts or other fasteners, or alternatively other fastening features or mechanisms, such as clips, clamps, or adhesives. The fixed upright portion 9 may also include one or more sleeve portions 9d, 9e for receiving another system component, such as an upright inner sleeve, described further below. Each of the sleeve portions 9d, 9e, may include, for example, one or more holes or openings 9c therein for use in securing components to one another.
(37) FIG. 4 is a Photostat showing an example upright inner sleeve 15 for a fixed position wheel 15 (e.g., a sleeve having holes or openings to allow variable height adjustment, such as up to 35) with one or more height adjustment openings 15a and an attached jack for fixed wheel 13 (e.g., jack with variable lift height range, such as 0 to 15) having a fixed position wheel 3, such as a fixed position tire (e.g., a pneumatic tire that does not swivel or otherwise move relative to the axial direction of the attached jack 13; for example, such wheel is therefore unusable or less usable for directing an object to which the wheel may be attached) in turn attached thereto.
(38) FIG. 5 is a Photostat showing another example upright inner sleeve 25 for a directional wheel 27, the upright inner sleeve 25 having one or more height adjustment openings or holes 25a and an attached jack for directional wheel 11 (e.g., a manually cranked or hydraulically driven jack) with caster or other similarly operating directional wheel feature 26 (e.g., an example 8 caster assembly) and mounted directional wheel 27, such as dual tires. Such caster assembly or other similarly operating directional wheel feature 26 may be attached to the lower end of each jack 11, for example, so as to allow an object to be transported, to which such jack 11 is attached, to be moved about an area, such as the roof a building. FIG. 6 is a Photostat showing the upright inner sleeve 25 and attached jack 11 of FIG. 5 for a device or system in process of being moved about, in accordance with aspects of the present disclosure.
(39) FIG. 7 is a Photostat showing a side view of the example mounting plate 2 of FIG. 2. The mounting plate 2 may be attached to an example object to be transported (e.g., a heating and air conditioning or HVAC unit) and to various other components of a device or system in accordance with aspects of the present disclosure, as will be described further below. As shown in FIG. 7, the mounting plate 2 may include one or more openings or other features for use in attachment of the mounting plate 2 to the object to be transported and/or other features of the device/system. For example, one or more bolts 30 having engagable nuts 31 may extend through one or more openings in a first extending body portion 2a of the mounting plate 2. In addition, one or more attachable mounting tabs 4 may also be attachable to the mounting plate 2, such as via a second extending body portion 2b of the mounting plate 2. FIG. 8 is a Photostat showing another view of the example mounting 2 plate of FIG. 7 and attachable mounting tab 4 for use in attachment to an example object to be transported, in accordance with aspects of the present disclosure.
(40) FIG. 9 is a Photostat showing the example fixed upright portion 9 being initially engaged with the upright inner sleeve 15 of a device or system in accordance with aspects of the present disclosure. The upright portion 9 may include an approximately 44 square cross-sectional tube of approximately 4 length. FIG. 10 is a Photostat showing the example fixed upright portion 9 being further engaged with the upright inner sleeve 15 of a device or system in accordance with aspects of the present disclosure. As shown in FIG. 10, the inner sleeve 15 may be slid into openings in the attached sleeve portions 9d, 9e of fixed upright portion 9. FIG. 10 also shows example pins (e.g., pin 35) that may be used to pin the fixed upright 9 relative to the upright inner sleeve 15. The inner sleeve 15 may have an attached (e.g., welded) jack 13 and fixed wheel assembly 3. The openings 15a in the inner sleeve 15 enable the inner sleeve 15 when engaged with and pinned to fixed upright portion 9 to be variable over a greater overall length range than, for example, would be allowed solely by the extension limit of a conventional 15 jack. In use to increase lift, the jack 13 may simply be retracted, the securing pins (e.g., pin 35) removed, and the fixed upright 9 then slid relative to the inner sleeve 15 to a new position. With the wheel 3 on the ground, for example, the sleeve 15 may then be re-pinned to change height. This process may be repeated for jacks 13 placed at multiple locations about an object to be transported. An additional 15 of lift, for example, via the jacks 13, may then be obtained in lifting the object to be transported.
(41) FIG. 11 is a Photostat showing a first pin 35 to be engaged with the fixed upright portion 9 and the upright inner sleeve 15, such as via the opening 9a in sleeve portion 9d of fixed upright portion 9. FIG. 12 is a Photostat showing the first pin 35 and a second pin 36 engaged with the fixed upright portion 9 via openings 9a, 9b, respectively, and via corresponding openings in the upright inner sleeve 15, such that the fixed upright portion 9 and upright inner sleeve 15 do not move relative to one another.
(42) FIG. 13 is a Photostat showing an example mounting plate 2 in process of being attached to an example object to be transported 130, in accordance with aspects of the present disclosure.

(57) FIG. 32 shows an example upright inner sleeve 15 and attached jack 13 and wheel 3 being lifted through a relatively small roof opening, in accordance with aspects of the present disclosure. The unassembled portions of the system may be brought through a typical roof hatch for a building. The parts may be hoisted, for example, through a rooftop hatch using a rope or the like (e.g., a diameter rope). In some variations, the portions of the device or system may each be able to fit though any roof hatch having an opening of about one square foot or greater.
(58) In use, after the parts are hoisted to the rooftop (FIG. 32) and initial parts assembly is completed, as shown in FIGS. 2-5 and 9-12, and a plurality of plates 2 are bolted to the rail of the rooftop air conditioner (FIG. 13). Four plates 2 may be used, for example, with one plate 2 being placed at each corner of the object to be transported (e.g., object 130 as shown, for example, in FIG. 22). The plate 2 may be attached to the object to be transported via a mounting tab 4 (see, e.g., FIG. 26). Only a single wrench or socket (e.g., wrench or socket) may be needed in order to bolt the system in place, since the mounting tab 4 may be prevented from turning via the rail, thereby allowing a nut to be tightened without the mounting tab 4 spinning. A cushioning bracket 6 may also be used, e.g., via a magnet attached to an angle bracket with a flexible pad (e.g., cork or rubber) to cushion each fixed upright 9 when contacting the object to be transported, so as not to damage the unit (FIGS. 17-19).
