There have been various tools developed for handling hanging flower baskets including:
U.S. Pat. No. 4,063,768 (Denis) describes a hanging flower basket tool where the basket is supported on the bottom by a single rod and along an edge by a single ring.
U.S. Pat. No. 4,607,871 (Kirkman) describes a tool for hanging baskets where the basket is only supported by a single gimbaled support ring which pivots during use.
U.S. Pat. No. 5,809,850 (Tickner) describes a tool for installing and removing compact fluorescent lamps. This tool uses grippers that hold the lamp in a fixed position during movement.
US 2009/0014696 A1 (Stone) describes a lifting device for moving a pot that is mounted on its side (i.e., not a hanging basket).

The explanations and illustrations presented herein are intended to acquaint others skilled in the art with the invention, its principles, and its practical application. Those skilled in the art may adapt and apply the invention in its numerous forms, as may be best suited to the requirements of a particular use. Accordingly, the specific embodiments of the present invention as set forth are not intended as being exhaustive or limiting of the teachings. The scope of the teachings should, therefore, be determined not with reference to the above description, but should instead be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled. The disclosures of all articles and references, including patent applications and publications, are incorporated by reference for all purposes. Other combinations are also possible as will be gleaned from the following claims, which are also hereby incorporated by reference into this written description.
The teachings herein are related to tools for handling hanging baskets which provide improved strength in handling baskets, and/or improved stability in handling the baskets and/or improved ability to handle hanging baskets of different sizes (i.e., having pots of different sizes), and/or improved ability to economically manufacture one or more components of the tool. Various solutions to these problems are described herein and it will be appreciated that any of these solutions may be employed alone or in combination with other solutions. Preferably, the bowl is sufficiently symmetric so that that tool can be used at any rotational angle about a central axis.
The tool generally includes a bowl component for holding the hanging basket. In use, the bowl should be connected to a pole sufficiently long for reaching the hanging basket and lifting it over a hanger support such as a rod or bracket from which the hanging basket hangs. The pole may be attached to the bowl (e.g., included with the tool) or the tool may be provided without the pole. Preferably, the tool includes a connector component for connecting the pole to the bowl. The connector component may provide a permanent connection or may be a reversible connection for attaching the bowl to the pole. A reversible connection may be particularly useful for multiple reasons including the ability to use multiple sized bowls (e.g., bowls having different maximum diameters), the ability to use different length poles, the ability to switch between a fixed length pole and a variable length pole (e.g., a telescoping pole), the ability to use a double-sided bowl, or the ability to quickly repair a tool having a damaged pole; many of these features are described in more detailed herein.
The bowl should be sufficiently large to hold at least a portion of a hanging basket. Although the pot of a hanging basket may fit entirely in the bowl, it will be appreciated that a significant portion of the hanging basket may extend above a top region (for example an upper rim region) of the bowl. This may be particularly useful when the hanging basket includes plant(s) that overhang the sides of the pot, so that the amount of the plant that is damaged between a wall of the pot and a wall of the bowl is reduced or minimized.
The bowl preferably has an open structure or is made of a generally transparent material so that the positioning of the hanging basket into the bowl can be easily seen from the position of a handler (e.g., located generally below the hanging basket). For example, the bowl may include a series of openings that are sufficiently in size and number so that the hanging basket can be observed as it passes through the top of the bowl and enters the cavity of the bowl. Preferably the bowl has a sufficient number of openings so that the hanging basket can be observed (e.g., by a user) from any angle of rotation of the bowl about an axis of the bowl. The combined area of the openings preferably is about 10% or more, more preferably about 20% or more, and most preferably about 30% or more of the total surface area of the bowl. If the combined area of the openings is too small, it may be difficult to observe the hanging basket entering the bowl. If the combined are of the openings is too high, the walls of the bowl may not provide sufficient strength to support the hanging basket. Preferably the combined area of the openings is about 92% or less, more preferably about 80% or less, even more preferably about 70% or less, and most preferably about 65% or less of the total surface area of the bowl.
The bowl may have a continuous concave surface.
The bowl may have one or more side walls. The following description of the side wall(s) includes the openings in the side wall as part of the side wall. Preferably, the bowl has a single side wall. For example, the side wall may have a cross-section with a horizontal plane that is generally arcuate and/or continuous. Preferably a cross-section of a side wall with a horizontal plane is generally circular. The cross-section of a side wall with a horizontal plane may have a shape that is generally similar to a cross-section of a pot of the hanging basket (e.g., a cross-section with a horizontal plane).
The bowl may be characterized by a central axis (e.g., in a generally vertical direction).
The bowl may have a rotational symmetry. The bowl may have axial symmetry.
The bowl includes a base portion near the bottom of the bowl. The base portion may be a portion of the side wall(s). For example, the side wall of the bowl may slope down towards a central axis of the bowl. The base portion may be a component separate from the side wall(s) and preferably connected to the side wall(s). For example, a base portion may be a generally horizontal component with the side wall(s) extending from the edges of the side base portion.
The bowl may have a rim near a top.
The rim may be reinforced. The rim may be reinforced with multiple layers of material. The multiple layers are generally connected. Two adjacent layers of the multiple layers may be in contact with each other or may be spaced apart. The rim may include two spaced apart layers that are reinforced by a plurality of ribs connecting the spaced apart layer (e.g., below the top of the rim). The ribs preferably are generally vertically oriented walls extending in a generally radial direction from a first wall (e.g., an inner wall) to a second wall (e.g., an outer wall). The ribs are preferably spaced along the circumference of the walls. Preferably the number of ribs is about 4 or more, more preferably about 6 or more, even more preferably about 8 or more, and most preferably about 12 or more.
The bowl may be reinforced near the bottom of the bowl. For example, the bowl may include a plurality of ribs connected to and extending radially inward from a horizontal wall of the bowl. The rib preferably contacts the horizontal wall in a region where the horizontal wall contacts the bottom region (e.g., the bottom wall of the bowl. The rib may be position below the bottom of the bowl, above the bottom or the bowl (i.e., inside the bowl), or both (e.g., some ribs may be above the bowl and some ribs may be below the bowl. If the rib is positioned below the bowl, a side wall of the bowl preferably extends vertically below a plane defined by the bottom of the bowl. Preferably the ribs for reinforcing the bottom of the bowl is a generally vertical wall extending in a radial direction and in contact with both a horizontal wall of the bowl (e.g., above or below the bottom of the bowl) and in contact with a bottom wall of the bowl (e.g., at a top surface or a bottom surface of the bottom of the bowl). The ribs preferably are spaced apart along the horizontal wall. Preferably the number of ribs is about 2 or more, more preferably about 3 or more, and most preferably about 4 or more.
A wall of the bowl may be formed by a plurality of spaced apart parallel horizontal elements (e.g., each having a generally circular circumference in along the horizontal direction) connected by a plurality of vertical elements (e.g., extending at least partially in a vertical direction). The vertical elements may be straight or may be arcuate. The vertical elements may extend from the base portion to a top portion (e.g., a rim portion or most distal horizontal element) of the bowl.
The bowl (e.g., the support structure of the bowl) may be formed of any material or combination of materials capable of providing sufficient support for holding the hanging plant and sufficient stability for handling the pots (e.g., for handling pots of different diameters).
The support structure (i.e., support components) of the bowl may be formed of a polymeric material, a metallic material, a plant-based material, or any combination thereof.
The support structure of the bowl may be formed of a polymeric material capable of molding, preferably via injection molding.

Metallic materials that may be employed for the bowl include ferrous metals and non-ferrous metals.
Examples of ferrous metals include high carbon steel, medium carbon steel, stainless steel, and other alloys including 50 weight percent or more iron. Preferred non-ferrous metals include aluminum and aluminum alloys having an aluminum concentration of about 50 weight percent or more.
The tool according to the teachings herein may be employed in a greenhouse environment, having temperature, sunlight, and humidity characteristic of a greenhouse. The tool may also be exposed to direct contact with water. Preferably the tool is resistant to corrosion at these conditions. For example, the material for the structure of the bowl preferably is resistant to corrosion. If a material is employed in the structure of the bowl that is not corrosion resistant, the bowl preferably includes a coating or other protective barrier layer to reduce or minimize corrosion of the material.
Pole and/or Connector Component
The tool includes a pole or includes one or more connector features (e.g., connector component) for attaching to a pole. Preferably, the pole is arranged so that the axis (i.e., the length) of the pole is parallel with the central axis of the bowl.
The connector feature may be any feature suitable for securely connecting the pole to the bowl so that the weight of the hanging basket can be transferred to the pole while the pole maintains a generally fixed orientation relative to the bowl. For example, the central axis of the bowl is maintained parallel to the axis of the pole. Preferably the central axis of the bowl is the axis of the pole. The connector feature may permanent connect the pole to the bowl. As used herein, a permanent connection is a connection which cannot be reversed by hand, without use of tools. Preferably the connector feature is a reversible connection feature which can be reversed by hand without the use of any tools. For example, the connector feature may include an internally threaded hole for receiving a threaded end of the pole. As another example, the connector feature may include a quick release clamp, a set screw that is hand tightened, a compression fit, or any combination thereof. As another example, an end portion of the pole may go through the bowl
The pole may have any shape. The pole may be characterized by a length direction and a second direction (e.g., width or diameter) perpendicular to the length direction, and a third direction orthogonal to the length direction and the second direction (e.g., thickness or diameter). Typically, the third direction is the same as or smaller than the second direction. The ratio of the length direction to the third direction preferably is about 25 or more, more preferably about 30 or more, and most preferably about 40 or more.

The gripping region preferably is located in one or more portions along the bottom half of the length of the pole, more preferably along the bottom quarter of the length of the pole. The gripping region may include an elastomeric material. The gripping region may include a region generally contoured to match (e.g., mate with) the shape of the fingers of one hand or both hands. The cross-section of the pole may be generally uniform or may vary along the length of the pole. For example, the cross-section at a length ¼ from the top and at a length ½ from the top of the pole may be the same or may be different.
The pole may have a flange component for supporting some or all of the weight of the bowl and/or the hanging basket. If employed, the flange component is positioned near an end (e.g., a top end) of the pole and below the bowl. A flange component may be permanently or removably attached to the pole. The flange component may function by transferring downward gravitational forces from the bowl to the pole. If employed, the flange component may function as part of the connector component.
The connector component may include an internally threaded component for receiving a threaded portion of a pole. Such a connector component may transfer some or all of the weight of the hanging basket to the pole. For example, the connector component may transfer weight from the threadings of the connector to the threadings of the pole.
Stabilization Feature (i.e., Stabilizing Component)
The bowl according to the teachings herein preferably includes one or more stabilization features. Stabilization features preferably are located or integrated into a side wall of the bowl and or a bottom wall of the ball. The stabilization features preferably are located on an inside surface of the bowl or extend into the cavity of the bowl.
A stabilization feature may be integrated into a connector component. For example, the connector component may include a stabilization feature that fits into a raised portion in the bottom of a hanging basket for reducing the lateral movement of the hanging basket with respect to the connector to the bowl of the tool. The connector component may be
A stabilizing component and a connector component may be attached together. A stabilizing component and a connector component may be co-molded (e.g., co-injection molded), preferably from the same material.
The stabilizing component may be a feature that increases the static coefficient of friction of a hanging basket against a support structure. For example, the stabilizing component may include a layer of a material that increases the static coefficient of the support structure and covers at least a portion of the support structure. A stabilizing component and a support structure (e.g., a support component) may be attached together. A stabilizing component may be a coating or other layer covering at least a portion of a support structure. Preferably, the stabilizing component and the support structure are formed of different materials. The stabilizing component may be applied as a layer over the support component. The stabilizing component may be over-molded over the support component. A stabilizing component and a support structure may be co-molded (e.g., co-injection molded), preferably using different materials.

The stabilizing component may include a bowl wall having a first wall portion proximate a base of a bowl and a second wall portion generally above the first wall portion and extending towards a rim or other distal portion of the bowl, wherein the second wall portion is separated by the first wall portion by a shelf that is generally perpendicular to the first wall portion, wherein the second wall portion provides a larger opening than an opening of the first wall portion (e.g., a radius of the second wall portion is greater than a radius of the first wall portion).
Bowl with One or More Shelves
The tool may include a bowl with multiple shelves for receiving hanging baskets of different sizes. For example, the bowl may include a shelf at an elevation above the floor (e.g., bottom) of the bowl. Generally. the shelf does not cover the floor of the bowl. For example, the shelf may have an inside radius that is greater than an outside radius of the floor of the bowl. Generally, the shelf has an outside radius that is greater than an outside radius of the floor. The width of the floor may be the distance between the outside radius of the floor and the inside radius of the floor. A bowl may have one or more additional shelves positioned at an elevation above the first shelf. Each successive shelf typically has a higher inside radius and a higher outside radius. When handling a small hanging basket (e.g., having a radius at its bottom that is smaller than the radius of the floor), the hanging basket may rest on the floor of the bowl. However, when handling a second larger hanging basket having a bottom radius between the outside radius and the inside radius of the first shelf, the second hanging basket may rest on the shelf. As such, each shelf may accommodate a different range of hanging baskets sizes. The range for each shelf may be approximated by the outer and inner radius of the shelf.
When the bowl includes one or more shelves, different portions of the bowls (e.g., different wall portions or different shelves) may provide support to different pots based on the dimensions of the pot.
The stabilizing component may include one or more features that allow the bowl to exert sufficient compressive forces on the pot so that movement is reduced, minimized or eliminated.
The bowl may be constructed so that a portion of the bowl flexes outward (e.g., the bowl increases in diameter at least locally) when contacted by a hanging basket after it enters the entrance of the bowl. As the bowl flexes outward, it may apply a compressive force against the hanging basket. For example, the compressive force may be applied along a portion of the hanging basket near a bottom corner (e.g., where a side wall of the hanging basket meets a bottom of the hanging basket).
The stabilizing feature may include a plurality of protrusion from the rising from the bottom of the bowl for interacting with a ringed wall near the bottom of the pot. For example, the bowl may include a bottom portion having 30 or more flexible protrusions aligned generally vertically (preferably having a taper, and/or having generally circular cross-section) for receiving a portion of a wall of a pot (e.g., a peripheral portion of a wall of a pot (preferably, at least 4 of the protrusions are below the pot and at least 4 of the protrusions surround the pot). Preferably, the protrusions are spaced sufficiently far apart to reduce or minimize interference with the pot being supported by the bowl (preferably the protrusions are spaced apart by about 4 mm or more from the nearest protrusion, as measured from center to center). Preferably, the protrusions are sufficiently large so that they are not easily deflected (e.g., the diameter at mid-height preferably is about 2 mm or more, more preferably about 4 mm or more). Preferably the protrusions have a length (e.g., in the vertical direction) sufficient long for preventing the pot from lateral motion and/or sufficiently short for reducing contact between the bottom of the pot and the protrusions (e.g., about 3 mm or more, or about 5 mm or more, or about 7 mm or more, and/or about 25 mm or less, or about 20 mm or less, or about 15 mm or less, or about 12 mm or less).
Multiple Bowls
The tool may include one bowl, or may include two or more bowls. When provided with two or more bowls, the different bowls preferably have different sizes so that the tool can be adapted for handling hanging baskets of different size. For example, the tool may include a first bowl having an entrance having a first size (e.g., a first diameter) that is greater than the size (e.g., second diameter) of an entrance of a second bowl. When handling a relatively large hanging basket, the tool may be assembled so that the first bowl receives the hanging basket. When handling a relatively small hanging basket, the tool may be assembled so that the second bowl receives the hanging basket. When using the first bowl for handling a hanging basket, the second bowl may be attached to the pole or may be separate from the pole. When using the first bowl (e.g., an upward facing first bowl), If the second bowl is attached to the pole, the second bowl preferably is downward facing (e.g., with the pole going through the bowl). One, two or more bowls may be arranged (e.g., in a nesting manner) facing downward.
The tool may include two bowls having entrances (i.e., for receiving a hanging basket) that face in opposite directions, or that can be arranged so that the entrances face in opposite directions. The tool may include a first bowl that is attached to a second bowl. For example, a first bowl and a second bowl may share a common structure, such as a common wall, a common bottom portion, or a common connector component. Two or more bowls may be provided that are separable. The two or more bowls may include bowls that are capable of nesting together (e.g., all of the bowls may be capable of nesting together). When the tool includes three or more bowls, it is preferred that at least two bowls are capable of nesting together so that all of the bowls can be attached to the pole while using the tool. When the tool includes two or more bowls attached to the pole, it is preferable that at least one of the bowls faces downward and at least one of the bowls faces upward.
The tool preferably includes one or more features that provides resistance to impact (e.g., to the bowl, to the connection component, to the pole, or any combination thereof). For example, the bowl should be made of a material that will not crack when dropped from a height corresponding to the height of the bottom of the hanging basket. Preferably, the tool does not crack when dropped from a height of about 10 feet or more, or about 15 feet or more (e.g., onto a concrete, asphalt, stone, or dirt surface).
The tool preferably includes one or more features that provide resistance to UV light. The tool should be able to withstand the light exposure that may be experienced in a greenhouse (e.g., for a period of 1 or more years, 3 or more years, or 5 or more years) without experiencing cracking due to UV light exposure that affects the functionality of the tool. If the tool includes a material that is generally susceptible to cracking or other damage from UV radiation, the material preferably includes a sufficient amount of UV stabilizer and/or a sufficient coating so that such degradation is retarded or eliminated (e.g., for at least 1 year, at least 3 years, or at least 5 years).
The tool preferably includes one or more features that provide resistance to corrosion. The tool should be able to withstand the high temperature and humidity that may be experienced in a greenhouse (e.g., for a period of 1 or more years, 3 or more years, or 5 or more years) without experiencing cracking due to corrosion that affects the functionality of the tool. If the tool includes a material that is generally susceptible to cracking or other damage from UV radiation, the material preferably includes a sufficient amount of stabilizers and/or a sufficient coating so that such corrosion is retarded or eliminated (e.g., for at least 1 year, at least 3 years, or at least 5 years).
The material(s) for the bowl and/or the pole may be selected based on one or more of the following needs (in addition to the other needs discussed herein): a light weight tool for repetitive use, a tool that is resistant to impact (for example when dropped from a position of being vertically extended), a tool that resists UV light at levels found in greenhouses, a tool that is corrosion resistant after exposure to climates (e.g., heat and humidity) typical of a greenhouse. Materials that may be used include metals, polymers, composite materials, ceramics, and fibrous materials. It will be appreciated that the tool may include different materials for meeting different needs.
For example, the bowl may include regions formed of a first polymeric material and regions formed of a second polymeric material (preferably the polymeric materials are co-injection molded with physical, chemical, or mechanical attachment between the two materials).

The bowl 50 may include an integrated connector component 57, such as illustrated in
A connector component may be a separate component 67 that includes a stabilizing feature 66, such as illustrated in
A tool 70 may include two or more bowls 60, 60′, 60″, such as illustrated in
A tool may be assembled with the entrance to one or more bowls facing upward and the entrance to one or more bowls facing downward. Preferably only one bowl is facing upward so that the viewing of the hanging basket as it is positioned into the bowl is not restricted. For example, the tool may include only the bowl 60′ for use in the upward facing direction 71 and the remaining one or more bowls 60, 60″ each having its entrance in the downward facing direction 73, such as illustrated in
The bowl may include one or more shelves 75 as a stabilizing component, such as illustrated in
The wall of the bowl may include a structural component 82 and a stabilizing feature 83, 83′, 83″ including a soft elastomeric material (i.e., having a flexural modulus less than the material of the structural component and/or having a Shore A hardness of about 80 or less) for providing a slip-resistant contact with the hanging basket. The stabilizing feature may include one or more of the features illustrated in
In one aspect, according to the teachings herein, the tool includes two bowls that are joined together with entrances that face different directions, such as illustrated in
The two bowls of the dual bowl component may be mechanically fastened or otherwise attached, such as shown in
A rim of a bowl may be reinforced, such as illustrated in
Any numerical values recited herein include all values from the lower value to the upper value in increments of one unit provided that there is a separation of at least 2 units between any lower value and any higher value. As an example, if it is stated that the amount of a component or a value of a process variable such as, for example, temperature, pressure, time and the like is, for example, from 1 to 90, preferably from 20 to 80, more preferably from 30 to 70, it is intended that values such as 15 to 85, 22 to 68, 43 to 51, 30 to 32 etc. are expressly enumerated in this specification. For values which are less than one, one unit is considered to be 0.0001, 0.001, 0.01 or 0.1 as appropriate. These are only examples of what is specifically intended and all possible combinations of numerical values between the lowest value and the highest value enumerated are to be considered to be expressly stated in this application in a similar manner. As can be seen, the teaching of amounts expressed as “parts by weight” herein also contemplates the same ranges expressed in terms of percent by weight. Thus, an expression in the Detailed Description of the Invention of a range in terms of at “‘x’ parts by weight of the resulting polymeric blend composition” also contemplates a teaching of ranges of same recited amount of “x” in percent by weight of the resulting polymeric blend composition.
Unless otherwise stated, a teaching with the term “about” or “approximately” in combination with a numerical amount encompasses a teaching of the recited amount, as well as approximations of that recited amount. By way of example, a teaching of “about 70” encompasses a teaching of 70, a teaching of 70+/−20%, a teaching of 70+/−10%, a teaching of 70+/−5%, and a teaching of 70+/−1%.
Unless otherwise stated, all ranges include both endpoints and all numbers between the endpoints. The use of “about” or “approximately” in connection with a range applies to both ends of the range. Thus, “about 20 to 30” is intended to cover “about 20 to about 30”, inclusive of at least the specified endpoints.
The disclosures of all articles and references, including patent applications and publications, are incorporated by reference for all purposes. The term “consisting essentially of” to describe a combination shall include the elements, ingredients, components or steps identified, and such other elements ingredients, components or steps that do not materially affect the basic and novel characteristics of the combination. The use of the terms “comprising” or “including” to describe combinations of elements, ingredients, components or steps herein also contemplates embodiments that consist essentially of the elements, ingredients, components or steps.
Plural elements, ingredients, components or steps can be provided by a single integrated element, ingredient, component or step. Alternatively, a single integrated element, ingredient, component or step might be divided into separate plural elements, ingredients, components or steps. The disclosure of “a” or “one” to describe an element, ingredient, component or step is not intended to foreclose additional elements, ingredients, components or steps.
It is understood that the above description is intended to be illustrative and not restrictive. Many embodiments as well as many applications besides the examples provided will be apparent to those of skill in the art upon reading the above description. The scope of the invention should, therefore, be determined not with reference to the above description, but should instead be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled. The disclosures of all articles and references, including patent applications and publications, are incorporated by reference for all purposes. The omission in the following claims of any aspect of subject matter that is disclosed herein is not a disclaimer of such subject matter, nor should it be regarded that the inventors did not consider such subject matter to be part of the disclosed inventive subject matter.
