DETAILED DESCRIPTION OF SOME PREFERRED EMBODIMENTS OF THE PRESENT INVENTION

With reference to FIGS. 1 and 3, only one possible version of the novel support arm 1 is illustrated. The support arm 1 comprises a main elongated portion 2 which is integral with a curved portion 3, which in turn terminates in an end portion or stop member 4 disposed outside of the plane containing the main elongated portion 2 and the curved portion 3 of the support arm 1.

The curved portion 3 is shaped and adopted to accommodate the passing therethrough of a pivot pin or bolt 5 for pivotally connecting one or two support arms 1 to the elongated main support member 6, which is shown in FIGS. 2 and 3.

Preferably, but not necessarily, the pivot pin or bolt 5 passes all the way through the elongated main support member 6. Preferably, but not necessarily, the pivot bolt 5 can be threaded at its end portion to mate with a threaded nut (not shown). The pivot pins 5 may preferably, but not necessarily, be any conventional bolts threaded at the end with a nut (not shown) for securing to the elongated main support member 6. Preferably, but not necessarily, washers (not shown) may be employed at either end or both ends of the pivot pin 5.

The elongated main support member 6 may be fabricated form any suitable material. Preferably, but not necessarily, the elongated support member 6 is fabricated from aluminum tubing.

With reference to FIG. 2, the elongated support member 6 with its pivotally connected support arms 1 are supported by a base member 7. Preferably, but not necessarily, the base member 7 may be fabricated from steel. The steel base member or base plate 7 is easily and quickly attached to the bottom of the elongated main support member 6 by any suitable means.

Two or more of the portable racks or trim towers 8 (shown in FIG. 2) may be spaced apart any desired distance for temporarily drying or storing a plurality of articles, such as, for example, pieces of wood trim. A cross section of a typical piece of wood trim 9 being supported by a support arm 1 is shown in FIG. 3.

FIG. 3 shows the support arm 1 disposed in a stable horizontal position when it is in use for holding various articles, such as pieces of wood trim 9. The phantom line position of the support arm 1 shown in FIG. 3 shows the support arm 1 that has been pivoted to a position where that particular support arm 1 is not in use.

The top portion of FIG. 2 also shows one of the support arms 1 pivoted substantially vertically when it is not in use. It should be noted that the novel structure and arrangement of the support arm 1 enables the end portion or stop member 4 thereof to bear against the exterior surface of the elongated support member 6 in the use position, as well as in the storage or non-use position.

Preferably, but not necessarily, the vertical spacing between adjacent support arms 1 when in use is approximately six inches.

The length of the support arm 1 can be any desired length, for example, 8 inches, 10 inches, 12 inches, etc. When used for holding wood trim 9, the support arms 1 may be 8 inches to accommodate easily three pieces of wood trim 9.

Alternatively, if the portable rack 8 is to be used for supporting heavy articles, such as galvanized pipe, the support arms 1 can be made suitably shorter, for example, two inches long.

Preferably, but not necessarily, the base member 7 may be one foot square by one-half inch thick.

The portable trim tree rack 8, preferably, but not necessarily, weighs 22 pounds, with each being constructed of aluminum tubing, a steel base and heat-treated metal support arms 1. The units 8 may be sold individually or in sets of three.

The portable rack 8 is the ideal tool for painters and finish carpenters. These portable racks 8 allow the job sites or paint shops to be multi-functional, well organized, and flexible, and are ideal for trim drying or storage.

FIGS. 4-6 show a second embodiment of the present invention in the form of a stand-alone rack 20 for holding clothing and other items. These figures also show an alternate embodiment of the support arms 21 having curved outer ends 22, and an end portion 23 through which is disposed a bolt 24 or pivot pin with an arrangement of washers 25, 26, 27 and 28 and a nut 29 at the opposite end of the bolts 24. The curved portion 23 terminates in a stop tab or end portion 31 disposed outside of (and preferably, but not necessarily, substantially perpendicular to) the plane containing the curved outer end 22, the curved portion 23, and main elongated portion of the support arm 21. The end portion or stop tab 31 functions similar to the abovementioned end portion or stop member 4.

In FIG. 5 it is shown that the arm 21 can be arrayed in its operational position perpendicular to the main post 30 of the rack 20, or in a storage position aligned with the axis of the main post 30 of the rack 20. Preferably, but not necessarily, the base member 32 and the supports arms 21 can be painted a first color, and the main post can be painted a second color, so that said first and second colors conform to the colors of a school, college, university, country club, city, state, province, or country.

FIGS. 7-9 illustrate an alternate embodiment for the support arm 40 which is provided with a stop tab 41 and a thickened upper portion 42 for improving the strength of the support arm 40. The stop tab 41 is disposed outside of (and preferably, but not necessarily, substantially perpendicular to) the plane containing the main portion of the support arm 41. The stop tab 41 functions similar to the abovementioned end portions or stop members 4 and 31.

The support arm 40 is fastened with a nut 43 and bolt 44 arrangement.

The various support arms 1, 21 and 40 shown in all of the drawings and photographs may be fabricated from nylon, plastic, or stamped steel, or any suitable material having the necessary strength and rigidity.

While the present invention has been described hereinabove with respect to only several preferred embodiments for illustrative purposes only, it should be understood that the present invention encompasses and embraces all modifications, variations, and changes to the basic inventive concept.

All such variations and modifications are intended to be embraced within the scope of the present invention.
