BACKGROUND OF THE INVENTION [0001]This application claims priority from provisional patent application entitled "Cart for Plumbing Supplies," Ser. No. 60/772,411 filed Feb. 10, 2006. The disclosure of provisional patent application Ser. No. 60/772,411 is hereby incorporated in its entirety. BACKGROUND OF THE INVENTION [0002]The present invention pertains to carrying devices for plumbing and electrical supplies. In the practice of trades in which tubular parts are used to assemble duct work and conduits such as plumbing drains and electrical conduits, the tradesperson must have a supply of fittings and couplers for interconnecting straight lengths of pipes. In the case of plumbers, the installation of new drain lines includes the assembly of lengths of straight tubular pipes joined by T sections, Y sections and by elbows of differing angles. Customarily the T's, Y's and elbows are carried in boxes or bins, typically thirty gallon trash cans, and are jumbled together such that a reasonably precise inventory is difficult to assess. The box, trash can or bin filled with fitting parts is carried to the job site and the plumber hunts through the parts to find the needed elbow or T or Y section as the plumbing lines are installed. If a necessary part is not found in the supply, a trip to the supply warehouse must be made, cutting into efficiency in the installation of the work. In addition, a great deal of time is spent hunting for the necessary parts and when a routine trip to the supply warehouse is made, a good idea of the number of fittings needed is not readily available. [0003]In addition, because the supply of parts in the box, bin or trash can is usually transported in the open bed of the plumber's pickup truck, rain or snow will infiltrate the container with the parts and must be drained or emptied. In the case of rain, holes can be placed in the bottom of the supply container but in the case of snow and ice, difficulties in finding the correct fitting part are magnified. What is needed is a carrying device which will allow the various fittings to be kept in an organized fashion and which will eliminate the underestimating of the supply of fitting parts on hand. Furthermore, a desirable carrying device will prevent rain or snow from collecting in the parts container. BRIEF SUMMARY OF THE INVENTION [0004]An improved carrying device for tubular parts used in construction of drain pipes and electrical conduits and other tubular ducting is provided. This invention includes multiple upstanding rods mounted to a base frame. The frame is equipped with a handle and a hinged lid which overlies the upper ends of the rods when the lid is in place during movement of the device. The lid is hinged on the handle such that it may be rotated away from the tops of the rods so that plumbing T's, elbows, or Y's can be placed on or removed from the rods. The rods are arranged to create an enclosure on the base frame to house milk crates holding tools, miscellaneous plumbing supplies, fittings which are not tubular, and elbows which do not permit passage of a rigid rod fully through them. The enclosure is also topped by the lid when the lid is lowered to its closed position. The carrying device may be equipped with a pair of wheels at one bottom corner of the device. The handle may extend above the height of the rods and the enclosure. [0005]A primary object of the invention is to provide a cart for transport of plumbing fittings onto a job site while providing a visual inventory of the fittings on hand and which keeps the fittings organized into groups. Another object of the invention is to provide a container which can transport tubular fittings in an orderly fashion. A further object of the invention is to provide a cart for tubular fittings or connectors which reduces the potential for a user to arrive at a work site without a suitable supply of needed fittings. Yet another object of the invention is to provide a cart which can be replenished with a supply of fittings when the user is present at the supply warehouse without purchasing parts or fittings for which an adequate supply already exists. [0006]These and other desirable objects will become apparent from examination of the detailed description which follows. BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWING(S) [0007]FIG. 1 is a front right perspective view of the preferred embodiment of the invention shown with assorted plumbing fittings carried thereon. [0008]FIG. 2 is a front elevation of the invention as shown in FIG. 1. [0009]FIG. 3 is a front left perspective of the preferred embodiment with its lid raised and with crates omitted. [0010]FIG. 4 is a side plan view of the invention as shown in FIG. 3. [0011]FIG. 5 is a top plan view of the invention as shown in FIG. 3 with the lid thereof shown in phantom to facilitate observation of the bottom structure of the invention. [0012]FIG. 6 is a rear elevation of the invention as shown in FIG. 3. [0013]FIG. 7 is a left front perspective view of an alternative embodiment of the invention. DETAILED DESCRIPTION OF THE INVENTION [0014]Referring to FIGS. 1 through 5 and initially to FIGS. 1 and 2, the invention cart 2 is shown in a typical in-use condition with cover 22 secured to upright frame 4 overlying crates 52 which are removingly situated within the volume defined by upright frame 4, base 6 and cover 22. [0015]Upright frame 4 is mounted to and supported upon base 6. Ground engaging wheels 8 are journaled on axle extensions 42 of rear lower cross bar 10. Upright frame 4 comprises plural spaced apart slender bars or rods 12 which upstand upon side rails 14, 16 and front rail 18 of base 6 with each rod 12 having an enlarged base 28. Rods 12 are preferably substantially perpendicular to the rails 14, 16 and 18. [0016]Plumbing fittings, namely plumbing T's 5, plumbing elbows 7 and plumbing Y's 9 may be carried along selected ones of rods 12. Rods 12 are spaced apart adequately to permit plumbing fittings 5,7 and 9 to be carried on adjacent rods 12. Preferably, rods 12 are spaced apart approximately three inches. Each rod 12 may be approximately one-quarter inch to approximately one-half inch in diameter, and are at least slender enough to allow plumbing fittings 5, 7 and 9 to slide easily therealong. [0017]Securing rod 38 upstands upon the front rail 18 generally at the midpoint thereof and comprises a bent segment 56 therealong which displaces top section 58 thereof toward handle 36. Top section 58 is generally parallel to rods 12. [0018]U-shaped handle 36 joins rear rail 10 of base 6 adjacent wheels 8. Grip section 60 of handle 36 is bent rearward from upright frame 4 approximately two and a half inches. [0019]Cover 22 is selectively retained to securing rod 38 at free end 40 thereof by locking pin 34. When pin 34 is removed from free end 40, cover 22 may pivot about hinge 24 thereby uncovering crates 52. Continue reading about Cart for plumbing supplies...
