Description
Background and Summary of the Present Invention
The present invention relates to hanging pots of a type generally used for plants and flowers. Such pots are commonly formed of a plastic material and have an annular flange or rim around the top thereof designed to accept some type of hanger device. The most popular of these pots is used in conjunction with a wire suspension member of the type including three or four wire strands connected together at the top by a hook. Each strand is inserted into one of a plurality of apertures in the rim of the pot and the end of the wire is twisted around the rim and itself to secure the wire.
Many problems arise with these conventional wire hangers; problems related to attachment and removal from the pot, and problems with adjusting the hangers so that the pots hang level. To ensure that the pots are level, each of the wire strands must be inserted through the rim aperture the same distance. Then, as the wire is twisted up around the rim of the pot and back around itself, the length of the strands must be maintained consistently around the pot. While this can be accomplished, it is difficult and time consuming. Therefore, in large scale nurseries the attachment of the hangers to the pots becomes an expensive procedure because of the time that personnel must devote to the task.
Further problems occur at the consumer level. If the pots are not hanging level, the wires can be difficult for the consumer to untwist and reposition. Or, the wires can be difficult to remove completely if the consumer wants to put the pot into a cachepot or basket.
Other types of hangers are disclosed in U.S. Pat. Nos. 4,440,371; 4,138,803; and 3,943,661. Generally, these patents are directed to container hangers which are made out of plastic and which have a variety of means for attaching the hanger to the container. However, it has been found that plastic hangers are subject to problems equal to or greater than those of wire hangers. Although the ends of the plastic hangers can be formed into a variety of shapes of hooks and other means for attachment to the pot rim, the plastic hangers are quite frequently subject to stretching and/or breaking under the weight of a potted plant. Additionally, if the plastic strands or plastic wires are not properly moded or extruded, the enlarged tips (such as in U.S. Pat. No. 3,943,661) snap off before ever being used or at the time they are attached to heavy pots.
It was to overcoming these disadvantages and to the provision of an improved and unique metallic wire hanger that the present inventor turned. Although metallic wire cannot be as easily shaped and molded as plastic products, metallic wire is far stronger and has a far longer life than comparable plastic hangers. The present hanger is comprised essentially of a metallic wire hanger having a hook suspension member and at least three depending connecting wires, and a container having a rim with a uniquely configured annular flange around the top thereof.
Each of the connecting wires includes, on the tip thereof, an enlarged member or "protuberance" which is readily inserted into complementarily-shaped slots in the annular flange or rim of the container and snapped into a retainer means or cavity beneath the rim, thus connecting the hanger to the container.
In the preferred embodiment the protuberance is formed by curling the end of the wire around to form an eyelet-shaped enlargement on the end of the strand. A plurality of identically shaped T-slots are equidistantly spaced circumferentially around the annular rim of the container.
An eyelet retainer means in the form of a cavity is provided beneath the rim and the leg portion of the T-slot to receive the eyelet and securely retain it in position within the leg portion of the T-slot. The cavity is formed by a block-like projection or boss which is molded into the under portion of the annular rim, beneath the leg portion of the T-slot. The leg portion of the slot extends through the wall of the block-like boss into communication with the aforesaid cavity which receives the eyelet. In the cavity there is also formed a nodule or bead molded onto a sidewall onto which the eyelet is snapped. The cavity is of such size and shape as to functionally engage the eyelet and hold it in place. The bead further ensures inadvertent dislodgement of the eyelet or protuberance.
Other forms of enlargements or protuberances might be formed on the end of the wires and will be discussed in detail below. For example, it is possible that the boss and cavity configuration could be eliminated and the protuberance merely held in place by virture of the protuberance being wider than the T-shaped slot in the rim, however, such construction would not offer all the advantages of the illustrated embodiment. It can be seen that the present invention achieves the objective of providing a metallic wire hanger for plant containers; which hanger overcomes the problems and disadvantages of prior designs. Further advantages and objectives wlll become apparent to those skilled in the art as the following detailed description is studied in conjunction with the following drawings.

Detailed Description of a Preferred Embodiment
Looking first at FIGS. 1 and 2 the improved plant container 10 is comprised of a hanger 20 and complementary container 30. The hanger 20 is formed of a metallic wire for strength and durability. The selected wire should be of a non-corrosive nature.
The hanger 20 is comprised of a hook-type suspension member 22, and at least three depending wire stand connectors 23 which connect the hook to the container 30. On the terminal ends of the strands 23 a protuberance or eyelet 24 is formed to releasably attach the strand to the container. Preferably, and as illustrated the protuberances 24 are all so formed so that the plane of the protuberance, in the relaxed position, is perpendicular to a radius passing outwardly from the center of the hanger 20. This prevents any tendency for the hanger to be skewed or under stress when assembled.
Protuberances 24 are preferably formed by curving the end of each strand around into an eyelet-shaped formation. While the wire end could be wrapped only one turn, thus forming a single loop eyelet, it is preferred to wrap the wire at least twice to form an eyelet comprised of a concentrically arranged pair of wire formations 25 and 26. Such a design actually reinforces the protuberance 24 and lessens the chance of distortion under the weight of the filled container. For further strengthening and reinforcement if desired, the wire may be concentrically wrapped as many as four or more turns, or the eyelet wires 25 and 26 may be soldered together to form a single, thickened eyelet wall that cannot be unwrapped. Additionally, multiple wraps increase the surface area and thus increase the support surface of the eyelet.
The container 30 is essentially for the most part, a conventionally molded plastic pot. There is an annular rim or flange 32 which surrounds the upper edge of the pot. The rim 32 is of an inverted U-shape having an outer side wall 33, a top wall 34, and an inner side wall 35 formed by the sidewall of the pot. The top wall 34, which is actually a laterally extending flange that supports and strengthens the upper edge of the pot, includes in the embodiment shown, a plurality of T-shaped slots 36 equidistantly spaced circumferentially therearound (120.degree. apart in the case of the three wire embodiment). Each T-shaped slot includes a cross-arm 38 and the leg portion 37 of the T-slot is substantially perpendicular to the side wall 35 of the pot, and the cross portion 38 is substantially perpendicular to the leg portion 37. Leg portion 37 is wider than the diameter of wire 23, but narrower than the diameter of protuberance 24.
In the preferred embodiment shown further in FIGS. 3, 4, and 6, a reinforcing plate or boss 40 is molded beneath the rim 32 and behind the rim 33 of the pot, in communication with and beneath slot 36. The leg portion 37 of slot 36 extends through the wall 42 of the boss 40 and therethrough to a cavity 42 in the center of the boss. The cavity 42 is the approximate depth and width of the protuberant member 24 for the purpose of frictionally receiving protuberance 24 therein. A bead 50 is molded into the sidewall 35 and extends into the cavity 42 as best illustrated in FIGS. 5 and 6 to serve as a locking means. This locking feature reduces the likelihood that the protuberance 24 will become inadvertently dislodged. The boss 40 is open at the bottom so that the wire may pass through the leg of the T-slot only when the protuberance is below the underside of the boss 40. The leg of the T-slot is just wide enough to accomodate the wire 23 and is slightly widened at the entrance to facilitate assembly. While to boss 40, as illustrated, is shaped to receive the eyelet-shaped protuberance 24, it is of course anticipated that the shape of the inner cutout 42 could be modified to receive a variety of shapes of protuberant members.
FIG. 6 best illustrates the bead or nodule 50 that extends into the open center of the eyelet to further lock the eyelet in place and its relationship with protuberance 24. The bead 50 can be a variety of shapes and sizes as necessary to accomodate a given protuberance and/or to vary the degree of protuberance retention.
To join the hanger to the container, the eyelet or protuberance 24 is inserted through the cross-arm 38 of slot 36 and downward to a position below the lower edge of wall 42. The wire strand 23 just above the protuberance is then pushed radially inwardly through the leg portion 37 of the slot 36 toward the wall 35 of the pot. (See FIGS. 3 and 6) The leg portion 37 of the T-slot is just wide enough to accomodate the diameter of the wire strands 23, and the cross portion 38 is just long and wide enough to allow the insertion of the protuberance 24 therethrough. Further, because of the manner in which the hanger 20 is fabricated, the protuberance 24 is automatically aligned with the cross-arm 38 of the T-slot 36. So aligned, there is no need to twist or otherwise manipulate the wire 23 or protuberance 24 during installation. The wire 23 is then pulled upwardly bringing the protuberance 24 into seated arrangement in cavity 42 with the eyelet 24 snapped onto bead 50.
While other and further modifications might be considered and made to the above described hanger, it is believed such modifications will remain within the scope of the claims below:
