[57] ABSTRACT A modular three-part preformed lightweight synthetic resin panel assembly comprising an aerial platform utility enclosure designed to be installed upon the outer structural surfaces of the frame members of an otherwise unenclosed aerial platform cage, wherein each respective panel member of the utility enclosure has an outwardly extending integrally molded tool and equipment storage compartment, with one such compartment being further provided with interiorly affixed laterally positioned rib panels to support transparent plastic accessory and parts drawers, wherein also the utility enclosure design is such that, when installed, there is no reduction in the available preexisting aerial platform operator/worker occupancy space.

7 Claim, 6 Ih'awing Figures U.S. Patent N0v.-4, 1975 Sheet 1 of2 AERIAL PLATFORM UTILITY ENCLOSURE ASSEMBLY BACKGROUND OF THE INVENTION The present invention relates to a modular three-part panel assembly which comprises an aerial platform utility enclosure designed to be installed upon an otherwise unenclosed aerial platform structure such as that exemplified and illustrated in US. Pat. No. 3,727,722 to Hedges et al.

Various types of enclosed aerial platform disclosures, which incorporate utility features of one kind or another, show platform means primarily designed for accomplishing specific aerially performed functions, such as exemplified by those aerial platforms developed for orchard harvesting operations as taught in US. Pat. No. 3,182,827 to Frost, dated May 11, 1965; US. Pat. No. 3,329,290 to Lowery, dated July 4, 1967; and US. Pat. No. 3,690,092 to Ross et a], dated Sept. 12, 1972. The disclosure set forth in US. Pat. No. 3,809,180 to Grove, dated May 7, 1974, teaches a partially enclosed aerial platform having installed at the forward vertical face thereof a pipe grab for engaging, holding, and 'lifting a length of pipe to an elevated work location.

Other enclosed aerial platform disclosures, such as those taught in US. Pat. No. 3,396,814 to Garnett, dated Aug. 13, 1968; US. Pat. No. 3,404,751 to Nosworthy, dated Oct. 8, 1968; and US. Pat. No. 3,625,305 to Mueller et al, dated Dec. 7, 1971, show additional utility features such as integrally formed toe offsets near the base of the platform, as well as integrally formed bumper members and dual purpose interior/exterior foot steps on the sides of the platform enclosure, in addition to detachable foot steps which are mountable over an upper edge of the platform enclosure and depend interiorly of the platform.

Yet another enclosed aerial platform design as shown in US. Pat. No. 3,695,390 to Leigh, dated Oct. 3, 1972, teaches the incorporation of integrally formed protrusions in the enclosing side walls of said platform, which protrusions serve as recesses for the storage of accessories employed by a workman in the platform, as well as incorporating also an integrally formed arm rest about the upper peripheral edge of the platform enclosure, in addition to a collapsible and/or removable cushioned seat within the platform.

Notwithstanding all of the utility features taught by the aforementioned disclosures, one of the inherent primary problems encountered upon the incorporation of such features in an enclosed aerial platform structure is the addition of weight, which additional weight operates over the aerial lift extension capability of the lifting means as it is employed to elevate and position said aerial platform at extended locations, thereby causing an excess load and resultant wear upon the intermediate lifting means connections, as well as the mounting point of the lifting means base and other fulcrum points of a lifting means not otherwise designed to accommodate the additional weight effect. The aforementioned additional weight factor is of particular significance when utility modification features are incorporated into the design of an enclosed uniconstructed aerial platform molded from synthetic resin material, where the weight of the resin required to form the aerial platform is determined by the thickmess of resin which is necessary to provide structural rigidity and strength, that being a considerably heavier weight 2 of resin material than would otherwise be required if the basic structural strength and rigidity for the aerial platform assembly were provided by some other less heavy construction means, and a thinner caliper of resin material could be advantageously utilized in accomplishing theutilitarian inventive ends.

Although the present invention is, in some structural and functional aspects, somewhat similar to the previously cited disclosures, the present invention nevertheless is distinguishable from the same in one or more ways, as will hereinafter be pointed out, as said present invention has serviceability features and new and useful advantages, applications, and improvements in the art of aerial platform utility enclosures not heretofore known.

SUMMARY OF THE INVENTION It is the principal object of the present invention to provide a modular three-part enclosing panel assembly for installation upon the two side and the front structural frame members of an otherwise unenclosed aerial platform cage structure, whereby the basic structural frame member strength and rigidity of said cage structure is imparted to said enclosing panel assembly members upon connection of the same thereto, thereby enabling the utilization of a lighter caliper lower weight enclosing panel assembly construction than would otherwise be possible while at the same time obtaining improvement features which enhance the utility of said aerial platform without inordinately increasing the basic structural weight thereof.

lt is an additional object of the present invention to provide an aerial platform utility enclosure assembly wherein the modular three-part panel members thereof are dimensionally formed into configurations which enables the direct retrofit attachment of said panel members to the respective side structural frame members of an otherwise unenclosed aerial platform cage structure without requiring dimensional modification, or any further forming, shaping, or cutting of said panel members.

It is another object of the present invention to provide an aerial platform utility enclosure assembly which It is still another object of the present invention to provide tool, parts, and accessory storage compartment drawer means whereby said drawers are fabricated from a transparent impact-resistant plastic material, thereby providing content visibility without requiring removal of the same.

It is still a further object of the present invention to provide tool, parts, and accessory storage compartment drawer support means which are designed to enable the employment of drawers of different multiples of depth of the basic unit.

It is also an additional object of the present invention to provide an aerial platform utility enclosure assembly which affords operator/worker occupant protection from the weather elements.

It is further an additional object of the present invention to provide an aerial platform utility enclosure assembly which furnishes the means for modifying an existing unenclosed aerial platform into a more utilitarian aerial lift component member than otherwise, without also requiring either further equipment modifications or involving a significant capital cost.

Yet another object of the present invention is to provide an aerial platform utility enclosure assembly which may be easily installed with standard tools by one not possessed of special skills.

Yet a further object of the present invention is to provide, as auxiliary utility components thereof, a set of attachment bars for quick-clamp mounting of cable splicing equipment.

Yet even another object of the present invention is to provide, as an additional auxiliary utility component thereof, a mounting bracket for detachable erecting either an enclosing protective canopy or an umbrella above the aerial platform utility enclosure assembly.

Details of the foregoing objects and of the invention, as well as other objects thereof, are set forth in the following specification and illustrated in the accompanying drawings comprising a part thereof.
