FOLDABLE PLANT SUPPORT STRUCTURE AND SYSTEM

Abstract: A foldable plant support system is described which provides a structure (10) within which a plant may be grown and physically supported, and over which a protective cover may be drawn to provide a protective environment for a plant contained within the structure (10), and an irrigation system. The system may be used as a "hotcap" or "mini greenhouse" with the support structure (10) and cover providing a protective environment for a seedling, new plant or the like. As the plant matures or as the weather dictates, the cover may be removed. The plant support structure (10) has two or more vertical members (12) and a number of cross members (14) connected to each other by a rotatable connector assembly (16) which provide the foldable feature of the structure. A vertical member (12) typically is rod-like and extends the entire height of the structure (10) and has attachment points (18) where it is attached to a connector assembly (16). The vertical member (12) also includes a staking structure (26), which is used to anchor the plant support structure (10) in place when in use. Loop shaped cross members (14) are connected to and extend laterally from the vertical members (12), and each has attachment points (18) for attaching the cross member (14) to a connector assembly (16). The connector assembly (16) provides a rotatable or pivotable attachment means for rotatably connecting a vertical member (12) to a cross member (14). An exemplary connector (16) is a hub and an axle assembly, with the hub having a passage for closely receiving and retaining one end of the axle.

Description: FOLDABLE PLANT SUPPORT STRUCTURE AND SYSTEM Field of the Invention The present invention is in the field of botanical support structures. More specifically, it relates to a seasonal use plant support structure that may be selectively adapted to provide both a protective environment and physical support means to a growing plant contained within it, and an irrigation system as well. Background of the Invention Plant supports have been used by gardeners ranging from the professional to the casual since before recorded time There truly have been innumerable alternatives devised for providing auxiliary support to a growing plant These alternatives can range from a simple stake in the ground to an automated, high-tech, controlled environment greenhouse Despite the plethora of alternatives historically available, the utility or desirability of any specific alternative is always defined by the totality of the circumstances impacting a given user In today's consumer society in the U S , both the hobbyist and the professional alike can have quite unique requirements for a plant support system that differ from their historical predecessors of even a few generations ago These include ready commercial availability (and all the inherent considerations that go into a commercial product), simplicity and ease of use, durability, broad application and efficient storage Of course, the industry has been motivated to develop a variety of plant supports to address one or more of these desirable features Some examples follow Booker, U S patent no 4,285,163, describes a four-sided, collapsible plant enclosure The enclosure may have screened sides for growing plants safe from rodents and other intruders However, the screened sides when practiced with the invention are not removable, nor does the invention have a top closure Vogel, U S patent no 4,073,091, describes another four-sided plant support that is foldable in the flat plane of the sides Benson, U S patent no 5,544,446, describes a plant support similar to Booker and Vogel in that it is foldable in the plane of its side, but provides for a support that may have more than four sides However, the means for staking the Benson support to the ground requires separate elements, whereas in Booker and Vogel the staking means are integral to the support Nahon, U S patent no 4,005,548, describes an alternative plant support which employs a plurality of upright rods and cross wires which may be assembled by the end user in order to provide the erected support structure However, after use, this structure requires substantial disassembly before it can be stored in a compacted configuration Another support structure assembled by the end user is that of Hillstead, U S patent no 5,179,799 However, the Hillstead support differs from the Nahon support in that it is readily disassembled for storage, but requires breaking the support down into its separate component parts There are still other structures that are neither collapsible nor foldable, but provide a reduced storage space requirement by nesting multiple structures when more than one structure is to be stored Such supports include those of Lemrick, U S patent no 3,299,569, and Glamos, U S patent no 5,174,060, and the prior typical cone- shaped tomato cage Additionally, there are plant support structures that although they are protective, they are not collapsible or foldable to provide a reduced volume configuration to increase storage efficiency For example, Gayle, U S patent no 4,858,380, describes a plant support having a wire mesh guard structure for completely enclosing a plant, with two different cross-sections and a lid for accessing the enclosed plant In view of the above, there is still the need in the field for alternative plant support systems that combine the benefits of having simple, integrated structural components, support structures that are easily erected for use and readily foldable for efficient storage, and which can provide both a protective environment as well as physical support as desired by the user Summary of the Invention The present invention is a foldable plant support system which provides a structure within which a plant may be grown and physically supported, and upon which a protective shroud, canopy or slipcover may be supported on the structure to provide a protective environment for a plant contained within the structure, and a soaker ring for irrigating the plant In use, the present invention may initially be used as a "hotcap" or "mini greenhouse" with the support structure and shroud providing a protective environment for a seedling, new plant or the like As the plant matures or as the weather or season permits, the shroud may be removed and the invention may provide physical support to the growing plant The structure is particularly adapted to support fruit bearing limbs of a plant contained within it as they grow outward from the structure The support system comprises a foldable plant support structure having two or more vertical members, a number of cross members which connect to the vertical members, the combination of which provides the structure of the support The vertical members and cross members are connected to each other by a number of rotatable connector assemblies which provide the foldable feature of the invention Besides a separate protective shroud which may be used to cover the structure and a plant contained therein, the plant support system also includes an irrigation means having a soaker ring for watering the plant Vertical members typically are rod-like and extend the entire height of the structure Vertical members may be constructed of any suitable material, such as metal or plastic, depending on the specific application for the structure Each vertical member has a plurality of attachment points where the vertical member is attached to a connector assembly The attachment points are spaced apart at similar positions along the length of the vertical members A vertical member has a cross-section configured to provide appropriate support for its use in view of its composition and construction The cross- section may be configured both as to its area and geometry as practicable by one of ordinary skill in the art The vertical member also includes a staking structure, which may be accomplished by having a section of the vertical member extend below the lowest attachment point on the vertical member The staking structure is used to anchor the plant support structure in place when in use by inserting the stake portion into the ground A cross member typically has a loop configuration, where the loop may be in the shape of a circle, an oval, a rectangle, or a triangle, as desired for a particular application Cross members are connected to and extend laterally from the vertical members Cross members may be constructed of any suitable material, such as metal or plastic, depending on the specific application for the structure The cross members also each have a plurality of attachment points for attaching the cross member to a connector assembly The attachment points on the cross members of a given support structure are similarly positioned along on each cross member. The connector assembly provides a rotatable or pivotable attachment means for rotatably connecting a vertical member to a cross member. Typically, two to six such connector assemblies are used to connect a cross member to as many vertical members. It is the rotatable interface between the vertical members and cross members provided by the connectors that accomplish the foldable feature of the plant support structure. The connector assembly may comprise any means which provides for rotation of the vertical member relative to the cross member. One such means is a hub and an axle assembly, with the hub having a cylindrical passage for closely receiving and retaining one end of the axle. The axle may be retained in the hub by application to the one end of the axle (the free end) of a retaining means. Such retaining means are known to the ordinary skilled artisan and include a fastener (such as a push or other type of nut), an upset, swaging, and crimping. The connector assembly may be attached to a vertical member or a cross member by any of a number of means known to one of ordinary skill in the art, such as welding to, molding in, forming of and clipping to the member. Attachment points are the positions on a vertical member or cross member where a component of a connector assembly is attached to the member. Attachment may be accomplished by any of a variety of means known to the skilled artisan. These include welding, soldering, molding, forming, and clipping the connector to the member. Where attachment is accomplished by clipping a connector component to a vertical or cross member, the member may be configured with a detent to fix the location of the attachment point and restrict movement of the connector once it is in place. A vertical member has a sufficient number of attachment points to provide the desired number of cross members for the structure. Typically, two to six attachment points are incorporated into each vertical member of a structure, but even more may be used if desired. In the plant support structure of the present invention, the cross-member may have between two and ten attachment points or even more for a specific application. For most typical applications, between two and six attachments are anticipated. The attachment points on cross-members are spaced apart either substantially symmetrically or at substantially equal distances Another feature of the present invention is a removable protective shroud or slip cover for covering the support structure when it is in use in an unfolded configuration The use of the shroud in combination with the support structure allows protection of a plant from adverse environmental conditions The shroud or slip cover may be constructed to generally protect a plant contained in the support structure from such specific risks as birds, frost, sun, insects and the like Appropriate materials for and configuration of (e g , mist net, fine mesh, or the like) the shroud or slip cover is selectable by the ordinary skilled artisan in consideration of the kind of protective environment desired An aspect of the protective shroud is that it may be configured as a fitted sleeve for drawing over the support structure To facilitate accomplishing this feature the support structure may be constructed to provide a smooth, non-catch outer aspect, such aspect to prevent or reduce snaring of the slip cover or fitted sleeve when installing it A further aspect of the fitted sleeve is that it may have one end that is closed or closeable The sleeve of the shroud may have a number of closeable openings through it to facilitate access to the plant contained therein Such openings may be self-closing or have other types of closures as practicable by the ordinary skilled artisan The protective cover feature in combination with the support structure provides a portable and easily erectable "mini-greenhouse" and the inherent benefits attendant therewith for growing plants Such benefits include preventing damage to a plant contained therein from frost, wind, hard rain, hail, sun scorch and animal pests The slip cover itself can include such benefits as being breathable and reusable Further, the slipcover may be left in place until the leaves of a plant contained therein touch the material of the slip cover Another feature of the present plant support system is a soaker ring which provides an irrigating means for use in association with a support structure The soaker ring is designed to be modular and have redundant interchangeable component parts This design facilitates interconnection of individual soaker rings to provide an irrigation system for use with multiple plant support structures Further, the modular and redundant aspect of the components enables the user to tailor the layout of the irrigation system to suit the user's individual need A further feature of the present invention is that similar support structures may be stacked one on top of another to provide a support structure of increased height Stacking may include fixing the upper structure to the lower structure This may be accomplished by fixing the bottom cross member of the upper structure to the top cross member of the lower structure Alternatively, the ground stake of the upper structure may be fixed to a cross member or vertical rods of the lower structure Various means of fixing the stacked support structure together are known and readily practicable by one of ordinary skill in the art A further additional feature of the present plant support system is a kit containing embodiments of the various features of the invention in a package The kit may contain embodiments of all of the features of the present plant support system or a subset thereof Brief Description of the Drawings Fig 1 is a perspective view showing the
