Hangers for plant baskets are well known. A conventional basket hanger includes an upper hook, from which a plurality of strands (typically three or four) extend downwardly. The distal ends of the strands are configured to attach to the flange of a plastic basket. The strands of conventional hangers are comprised of either mild steel wire which are welded or otherwise secured to the upper hook or, alternatively, the strands and hook are molded entirely from plastic.
Steel wire hangers offer the advantage of strength and are typically considered more aesthetically appealing than plastic hangers, but if the mild steel wire strands become bent during shipping or use, the bent wire strands will detract from the smooth, clean lines typically desired for hanging baskets. Accordingly, finished hanging basket products with mild steel wire hangers are more costly to package and ship because the mild steel wire hangers cannot be bent over for shipping in a box or shipping cage without detracting from their appearance, thereby requiring longer packages or shipping cages, even if the wire hangers are detached from the hanging baskets. Additionally, to attach a mild steel wire hanger to a hanging basket, a worker or purchaser will typically have to insert the end of the mild steel wire strands through holes in the basket flange and then bend and either twist or squeeze the end of the wire by hand to secure it to the basket. Depending on the diameter of the mild steel wire strand, in order to properly secure the hanger to the basket, a pliers or tool may be required. With or without tools, but especially without tools, if a worker's job duty is to attach conventional mild steel wire strand hangers to hanging baskets throughout the day, repeating this task several times a day can cause considerable pain and injury to the hands of a worker. Additionally, if a conventional mild steel wire strand hanger is not properly secured, the bend created at the bottom of the mild steel wire strand will open up and the hanger will detach from the basket even under normal conditions, let alone under high wind conditions when the basket is twisting and swaying.
Plastic hangers offer the advantage of allowing the hangers to be coiled or bent to fit into shorter packages when shipping the hanging basket, but plastic stranded hangers are necessarily larger in diameter than steel wire strand hangers to achieve the same tensile strength and therefore plastic strands are typically considered less aesthetically appealing. Furthermore, plastic strands and conventional mild steel wire strands are more susceptible to breaking in high wind conditions which can cause a hanging plant to twist and swing.
Accordingly, there is a need for a basket hanger which offers the advantages of a hanger with steel wire strands but which provides the advantages of allowing the hanger to be coiled or bent like a plastic hanger, but which will hold up to twisting and swaying in high wind conditions common in many areas. There is also a need for an improved manner of attaching the hanger to the basket which is more quickly and efficiently attached and does not require the use of a pliers or other tools.
Referring to the drawings wherein like reference numerals designate the same or corresponding parts throughout the several views,
The wire strands 16 are preferably comprised of spring steel. The spring steel wires may be finished by galvanizing, powder coating, painting, applying a polymer coating or any other desired finish. Use of spring steel allows the strands 16 to be coiled, twisted and/or significantly bent but due to the high yield strength of spring steel, the strands will return to their original straight shape without any deformation (provided the strands are not bent to the point of plastic deformation). Thus, the use of spring steel allows the strands 16 to be coiled or bent for placing into the shorter shipping boxes used for shipping plastic hanger baskets, but unlike mild steel or plastic hangers, the spring steel strands will “spring” back to their original straight shape without leaving unsightly bends or kinks in the strands that are common with conventional mild steel wire hangers and even with plastic hangers if the weight of the hanging basket and plant is not sufficient to remove the bends and kinks in the plastic strands. Additionally, the high yield strength of spring steel allows the strands to have a thinner diameter than is possible with plastic strand hangers, so the strands are less visible and do not detract from the appearance of hanging plants. The high yield strength spring steel also allows the hanger strands to be longer than is economically possible with plastic strand hangers, thereby offering a more elegant look for hanging plants.
Furthermore, unlike plastic strand hangers and conventional mild steel wire strand hangers which often break due to the twisting and swaying of the plant hangers in windy conditions, spring steel strand hangers are much less susceptible to breaking due to the high yield strength. Also, because of the higher yield strength of spring steel compared to mild steel, smaller wire diameters while still providing equal or greater weight bearing capacity than larger diameter conventional mild steel wire strands, thereby permitting the spring steel wire strands to be more easily attached to the baskets as discussed in greater detail below.
In addition, unlike plastic hangers which can deteriorate and become brittle after a single season and unlike conventional mild steel wire hangers which inevitably become bent after a single season or during storage over the winter months, spring steel hangers can be reused year after year without deterioration, and without unsightly bends and kinks.

By way of example, for a twenty-six inch long, four strand hanger 10, made from spring steel wire having a wire diameters ranging between about 0.04 inches and 0.07 inches (which may vary depending on the size of the basket to be supported), one suitable configuration for the clip 18 has been found to utilize a 3/16 inch radius for the 180 degree bend, and a length of 1¼ inches for the upwardly extending leg 18a, with a dogleg 18b of ⅝ inches bent outwardly at an angle θ of approximately forty degrees from the downwardly extending straight portion of the strand 16, and with a canted angle α of approximately ten degrees and an offset angle β for the dogleg 18b of approximately forty degrees. Such a clip has been found to allow workers to more quickly and easily attach the hangers to the baskets using only their fingers and thumbs without causing pain or injury to their hands despite performing the task all day. The clip configuration combined with the qualities of spring steel also eliminates the need for using a pliers or other tool which is typically necessary in order to bend and twist the wire of a conventional mild steel wire hanger strand, thereby amounting up to fifty percent (50%) labor savings.
It should appreciated that other dimensions and angles may be equally or better suited for the clip 18 depending on the diameter of the wire, the length of the hanger 10, the diameter of the basket 12, the width of the basket flange 22 and/or placement of the hole 20 in the flange 22, the number of strands 16 comprising the hanger 10, the weight of the plant or items intended to be supported by the hanger 10, wind or other environmental conditions where the hanger is intended to be used, and other factors. Accordingly, the scope of the invention should not be construed as being limited to the specific dimensions and angles of the clip 18 identified above.
