1. Field of the Invention
The present invention relates to a masonry project kit for use in connection with construction. The masonry project kit has particular utility in connection with building basements.
2. Description of the Prior Art
Masonry project kits are desirable for building basements. In the course of building a basement, it is frequently necessary to climb over and lift equipment over walls. It is also desirable to be able to access the floor of a basement without standing on it so that footprints will not be created. Masonry project kits provide a convenient mechanism for climbing walls and hoisting objects over walls. Furthermore, a platform attached to the ladder portion of the masonry project kit allows the user to finish a floor without contacting it with their feet. The hoist portion of the masonry project kit allows one or two people to lift equipment, such as a power trowel, easily.
The use of portable, collapsible hoist apparatuses is known in the prior art. For example, U.S. Pat. No. 5,265,742 to Stenger et al. discloses a portable, collapsible hoist apparatus. However, the Stenger et al. '742 patent does not have a V-shaped wall support, and has further drawbacks of lacking a base shaped like two rectangles perpendicular to one another with one overlapping corner.
U.S. Pat. No. 6,135,300 to Fox discloses a parapet-mounted hoist that is made from an elongated cradle. However, the Fox '300 patent does not have a V-shaped wall support, and additionally does not have a base shaped like two rectangles perpendicular to one another with one overlapping corner.
Similarly, U.S. Pat. No. 3,978,989 to Avila, Jr. discloses an extensible and collapsible portable derrick that can be disassembled and arranged in compact units. However, the Avila, Jr. '989 patent does not have a V-shaped wall support, and does not have a base shaped like two rectangles perpendicular to one another with one overlapping corner.
In addition, U.S. Pat. No. Des. 391,034 to Fukutomi discloses a roof car. However, the Fukutomi '034 patent does not have a V-shaped wall support, and also does not have a base shaped like two rectangles perpendicular to one another with one overlapping corner.
Furthermore, U.S. Pat. No. 4,621,741 to Boon discloses a readily disassembleable portable roof hoist mounted on the roof of a building for lifting heavy products to the roof from below that has a winch drum driven by a hydraulic motor. However, the Boon '741 patent does not have a V-shaped wall support, and further lacks a base shaped like two rectangles perpendicular to one another with one overlapping corner.
Lastly, U.S. Pat. No. 4,442,920 to Gronbeck et al. discloses a collapsible ladder that includes a plurality of platforms suspended from several rope segments. However, the Gronbeck et al. '920 patent does not have a hingedly attached platform, and has the additional deficiency of lacking a wall hanger.
While the above-described devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not describe a masonry project kit that allows building basements. The Stenger et al. '742 patent, the Fox '300 patent, the Avila, Jr. '989 patent, the Fukutomi '034 patent, and the Boon '741 patent make no provision for a V-shaped wall support or a base shaped like two rectangles perpendicular to one another with one overlapping corner. The Gronbeck et al. '920 patent does not have a hingedly attached platform, and has the additional deficiency of lacking a wall hanger.
Therefore, a need exists for a new and improved masonry project kit that can be used for building basements. In this regard, the present invention substantially fulfills this need. In this respect, the masonry project kit according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in doing so provides an apparatus primarily developed for the purpose of building basements.
In view of the foregoing disadvantages inherent in the known types of portable, collapsible hoist apparatuses now present in the prior art, the present invention provides an improved masonry project kit, and overcomes the above-mentioned disadvantages and drawbacks of the prior art. As such, the general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new and improved masonry project kit and method which has all the advantages of the prior art mentioned heretofore and many novel features that result in a masonry project kit which is not anticipated, rendered obvious, suggested, or even implied by the prior art, either alone or in any combination thereof.
To attain this, the present invention essentially comprises a ladder with an attached wall hanger and a hoist.

Lastly, in
In use, it can now be understood that wall hanger 30 is placed over the top of wall 96. The appropriate rungs 16 are hung on ladder brackets so that ladder 12 and platform 24 are at the appropriate height. Platform 24 is folded up and down as needed. Hoist 54 is mounted atop wall 96 by unscrewing wall support adjuster support 94, sliding wall support adjuster 88 until wall support 90 engages with a corner of wall 96, and screwing down wall support adjuster stop 94 to prevent wall support adjuster 88 from moving. First hoist tube 60 is rotated until clip 70 is above the load to be lifted. Clip 70 is then disengaged from retaining ring 72 and lowered by cranking winch 74. Clip 70 is attached to a load and then winch 64 is used to take up lifting cable 66, thereby lifting the load. First hoist tube 60 is rotated inside of hoist tube fitting 58 until clip 70 is above the desired resting place for the load. Winch 64 is then cranked to release lifting cable 66, thereby lowering clip 70. Clip 70 is then disengaged from the load, reattached to retaining ring 72, and any slack in lifting cable 66 is drawn over pulley 68 by cranking winch 64.
While a preferred embodiment of the masonry project kit has been described in detail, it should be apparent that modifications and variations thereto are possible, all of which fall within the true spirit and scope of the invention. With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. For example, any suitable sturdy material such as plastic, aluminum, titanium, or carbon fiber composite may be used instead of the steel ladder, wall hanger, base, wall support, wall support adjuster, wall support adjuster stop, hoist tube fitting, first hoist tube, second hoist tube, winch, pulley, clip, and seventh base support member described. Also, the steel cable lifting cable may also be made of rope, wire, or chain. And although building basements has been described, it should be appreciated that the masonry project kit herein described is also suitable for numerous lifting, climbing, and building activities.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
