Description

FIELD OF THE INVENTION

The present invention relates to cantilevered planter shelf systems, and more particularly relates to cantilevered shelves for displaying plants on the exterior of railings.

BACKGROUND INFORMATION

There are many devices in the field of railing planters that rely on the railing to support the weight of accompanying containers and plants. Weight, balance and variable railing widths are all challenges for traditional top rail devices. These challenges result in small containers or complex and awkward installations that may require tools. When hanging or perching planters on the railing weight can be a problem, and encumbering the top rail means the rail is not available for hand holding. Container gardens are a large part of the outdoor decorative experience but they take up valuable living space. Furthermore, plants tend to thrive in the sunny prominent places on covered porches.

SUMMARY OF THE INVENTION

The present invention provides a mounting and positioning system to display plants on elevated surfaces such as floor ledges of balconies, porches, decks, front stoops and the like. More particularly, the invention relates to displaying planters such as flowerpots and boxes on the exterior base of a railing by employing the floor ledge to cantilever a shelf that is stabilized against the interior of the railing. When installed, the cantilevered shelf base sits under the railing on the floor ledge and projects past the outer edge of the ledge. The back may rest flush and parallel to the interior of the railing. A top lip may project between adjacent balusters of the railing, and a stake may be inserted through at least one hole in the upper lip. Multiple holes may be provided through the top lip so the stake can accommodate a variety of railings and containers. The back spine may be oriented vertically to the base, and both the base and lip may be horizontal and parallel.

For installation, the base may slide under railings until the back spine rests parallel and flush to the railing. The base rests on the floor ledge and extends under the railing past the outer edge of the floor ledge. A planter may be placed on the base shelf at least partially under the top lip, then the stake may be inserted through the top lip and into the planter. A stake may thus be used to secure the planter in place by inserting the stake into the soil of a plant. The shelf staking system may be adjustable through a set of holes in the top lip that take a variety of railing thicknesses and planter or flowerpot designs into account.

The cantilevered planter shelves of the present invention expand display spaces for plants beyond the original footprint of elevated outdoor spaces, without inhibiting access to the top rail or relying on the railing to support weight. The present invention makes it possible to cantilever a shelf from a floor ledge beyond the railing to display plants. The cantilevered shelf is supported by the floor ledge, and does not require a railing to support weight. Multiple planters can be lined up to wrap around railings for larger scenic displays than previously possible.

Other benefits include locating flowers, vegetables and other plants out of the reach of animals, accessing rain water beyond roof lines, and having a top-down aerial view of plants as opposed to looking at the bottom of a hanging basket or the sides of traditional top rail planters. Additionally, in the case of climbing vines, railing balusters can act as a built in trellis.

An aspect of the present invention is to provide a cantilevered planter shelf for installation on a floor ledge adjacent to a railing. The planter shelf comprises a horizontally extending base, a vertically extending back spine extending upward from the base, and a planter securement member adjacent to the back spine horizontally extending in a region vertically above at least a portion of the base. The base comprises a rear support portion adjacent to the back spine structured and arranged to rest on the floor ledge when the planter shelf is installed, and a front extended portion structured and arranged to extend horizontally beyond an edge of the floor ledge when the planter shelf is installed. The back spine comprises a front surface structured and arranged to contact an interior surface of the railing when the planter shelf is installed.

Another aspect of the present invention is to provide a cantilevered planter shelf consisting essentially of a horizontally extending base, a vertically extending back spine extending upward from a rear portion of the base, a horizontally extending top lip extending forward from an upper portion of the back spine, and a stake movably mounted on the top lip.

A further aspect of the present invention is to provide a method of installing a cantilevered planter shelf on a floor ledge adjacent to a railing. The method comprises sliding a base of the planter shelf under the railing above the floor ledge, and contacting a front surface of a base spine of the planter shelf against an interior surface of the railing to thereby position the planter shelf in an installed free-standing position in which a supported portion of the base rests on the floor ledge, an extended cantilevered portion of the base extends beyond an edge of the floor ledge, and the front surface of the base spine maintains contact with the interior surface of the railing.

These and other aspects of the present invention will be more apparent from the following description.

DETAILED DESCRIPTION

FIGS. 1-6 illustrate a cantilevered planter shelf 10 in accordance with an embodiment of the present invention. The cantilevered planter shelf 10 includes a base shelf 12, back spine 20 and top lip 30. As used herein, the term “cantilevered”, when referring to the planter shelf, means that a portion of the base of the planter shelf is structured and arranged to extend outwardly beyond a floor ledge when the planter shelf is installed on the floor ledge with the back spine of the planter shelf adjacent to an interior surface of a railing. The extended portion of the base is not directly supported by the floor ledge since the floor ledge does not underlie the extended portion. However, the base also includes a supported portion that does rest on the underlying floor ledge when the planter shelf is installed. As used herein, the term “free-standing”, when referring to the planter shelf, means that the supported portion of the base rests on the support ledge, the back spine of the planter shelf contacts an interior surface of the railing, and no additional means of securement such as fasteners, brackets, straps, clips or the like are required to maintain the planter shelf in its desired position.

The base 12 may extend horizontally, the back spine 20 may extend vertically upward from the base 12, and the top lip 30 may extend horizontally forward from the back spine 20. As used herein, the terms “horizontally extending” and “extend horizontally” mean that a component of the planter shelf extends in a direction having a component in the horizontal direction. The term “extending in a horizontal plane” means that a component of the planter shelf, or a portion of the component, lies in a horizontal plane. As used herein, the terms “vertically extending” and “extend vertically” mean that a component of the planter shelf extends in a direction having a component in the vertical direction. The term “extending in a vertical plane” means that a component of the planter shelf, or a portion of the component, lies in a vertical plane. The base 12 includes a top surface 13, bottom surface 14 and perimeter edge 15. The base 12 has a supported portion 16 that rests on a floor ledge of a balcony, deck, porch, stoop or the like when the planter shelf 10 is installed. The base also has an extended portion 17 that is not supported by the floor ledge, thereby providing a cantilevered configuration when the planter shelf 10 is installed. A drain slot 18 is provided through the base 12. Although a single elongated drain slot 18 is shown, any other suitable number and shapes of drain slot(s) may be used. A bottom transition line 19 is provided between the base 12 and back spine 20.

The back spine 20 includes a lower portion 21 and upper portion 22, and has a front surface 23, rear surface 24 and perimeter edge 25. When the planter shelf 10 is installed on a floor ledge, the front surface 23 of the back spine 20 contacts the railing of a balcony or deck, as more fully described below. A top transition line 29 is provided between the back spine 20 and top lip 30.

The top lip 30 includes a rear portion 31, extended portion 32 and perimeter edge 35. Stake holes 38 are provided through the top lip. A stake 40 may be selectively inserted through the stake holes 38 of the top lip 30. The stake 40 includes a first downwardly extending rod 41, second downwardly extending rod 42 and upper connecting rod 43. The first rod 41 has a first stake tip 45, and the second rod 42 has a second stake tip 46. As shown in FIG. 6, the stake 40 may be selectively inserted in the stake holes 38 of the top lip 30. In the embodiment shown, the stake 40 is inserted in the front and middle stake holes 38. Alternatively, the stake may be inserted in the middle and rear stake holes 38. Although three stake holes 38 are shown in the embodiment of FIGS. 1-6, any other suitable number of stake holes may be used, e.g., from one to four or more. Although the stake 40 as shown includes two downwardly extending rods 41 and 42, any other suitable number of stake rods may be used, e.g., from one to four or more.

The planter shelf 10 may be made from any suitable types of materials including metal, plastic, wood, ceramic, composite, and the like. For example, the base 12, back spine 20 and top lip 30 may be made from sheet metal such as steel or the like having a thickness of from 0.01 to 0.2 inch, or from 0.05 to 0.1 inch. For example, the metal sheet may have a thickness of about 0.06 inch, and may be coated with zinc, paint, powder coating, anodized or the like. In a particular emebodiment, the steel sheet may be galvannealed or galvanized, and powder coated. The planter shelf 10 may also be made of plastics that are molded by conventional techniques such as injection molding. In the embodiment shown, the base 12, back spine 20 and top lip 30 are formed from a unitary sheet of material that may be bent, molded or otherwise formed into the configuration shown in FIGS. 1-6. Alternatively, the base 12, back spine 20 and/or top lip 30 may be made from separate parts that are fastened together, for example, by mechanical fasteners, hinges, adhesives, welding, or the like. The base 12 and/or top lip 30 may optionally be movable in relation to the back spine 20, for example, by hinges that allow them to pivot and lock into place. The perimeter edges 15, 25 and 35 may be formed or cut by any suitable means, for example, CNC cut from steel sheets with a decorative outline, such as a fleur de lis or any other desired design.
