Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates generally to new and improved extra large or macro planter structures for comparatively large plantings for use in large spaces, which planter structures may be assembled on-site into very large or macro planters of extremely long lengths, e.g., several hundred feet, to provide unusual and stunning visual effects. The new and improved planter structures include lighted cladding walls which may also function as lighted advertising displays visible from great distances owing to their size. Alternatively, the new and improved elongated planter structures, with or without lighting, may function as highly decorative and attractive barriers for pedestrian and/or vehicular traffic when established on busy streets or walkways. 
         [0003]    2. Description of the Related Art 
         [0004]    The planter state of the art in general as well as the specific lighted planter art is described in several issued U.S. patents, including: U.S. Pat. Nos. 3,030,735 to Bodkins; 3,935,671 to Soot; 5,741,061 to Lehmann et al.; 5,951,151 to Carel et al.; D619,924 to Jean-Pierre; and 7,805,885 to Luckett, as well as several published U.S. patent applications, including: US 2001/0034974 to Cameron et al.; 2003/0140557 to Lyon; 2006/0026898 to Klaus; 2007/0101646 to Licht; 2009/0300984 to Gordon; and 2010/0175318 to Ahmadi. These publications disclose various configurations of small or micro planters, some of which have modularity of components, and some of which disclose systems of illumination. However, there remains a need for macro planter units, which may be arranged and combined into large and striking planter constructions of hundreds of feet in length. The present invention fulfills the need for such large scale units, which may be lighted for special dramatic aesthetic effects. 
       SUMMARY OF THE PRESENT INVENTION 
       [0005]    In accordance with the present invention, a fundamental modular planter unit is formed either off-site or on-site, by erecting a skeletal rectangular parallelpiped frame, cube-shaped or elongated box-shaped, from wooden, thermoplastic, or metal beams and posts. The key elements are open-ended, molded high density polyethylene (HDPE) semi-cylindrical pipes or shells which are mounted to the frames. Decorative cladding in the nature of translucent plastic panels is attached to the frames to complete the modular units. Advantageously, the use of semi-circular pipe reduces the volume and weight of the planter when loaded with planting soil and promotes enhanced root growth of supported plants. Moreover, use of half-pipe reduces by approximately one third the amount of soil which would otherwise be required to fill a rectangular parallelpiped shaped container. 
         [0006]    As a further aspect of the invention, the half-pipe shells are of corrugated rib-trough construction, providing added strength by virtue of the ribs as well as discrete spaced fluid reservoirs at the bottom of the troughs. The maximum level or capacity of the reservoirs may be simply established and controlled by drilled or molded drainage ports arranged at predetermined levels and in predetermined numbers at and above the bottom of the shells. 
         [0007]    Importantly, the individual modular units are aligned and interconnected with adjacent half-pipe shells coaxially aligned and adjacent external cladding abutted to establish unitary planters of extreme lengths of many hundreds of feet. The attendant visual effects of such macro planters are extraordinary and are further enhanced by the integral internal lighting of the cladding walls in accordance with the invention. 
         [0008]    As will be understood, the new macro planter constructions of the invention may be utilized to display advertising as a supplement to their basic functionality as planters. Importantly, the long planters may be used as decorative substitutes for or as alternatives to common concrete traffic barriers. 
         [0009]    For a better appreciation of the new and improved modular planter units and the macro planters formed from gauging the units, reference should be made to the following detailed description taken in conjunction with the accompanying drawings.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0023]    Referring now to  FIG. 1 , the fundamental components of the new long macro planter structures are modular units comprising an external skeletal rectangular parallelpiped frame  10  and a generally cylindrical half-pipe shell  20  supported directly in the frame  10 . As will be understood, the frames and half-pipe shells are adapted to be juxtaposed end-to-end and interconnected to form long continuous planter structures, of hundreds of feet as shown schematically in  FIG. 9 . 
         [0024]    Specifically, the half-pipe shell elements are molded high density polyethylene (HDPE) sized with a diameter D of approximately  32  inches, length of approximately seven feet and depth of approximately  16  inches for easy handling and storage. The dimensions of the shells  20  may of course be varied without departing from the fundamental concepts of the invention. Advantageously, the shells  20  are of corrugated construction having a series of ribs  21  and troughs  22  between adjacent ribs defined by cylindrical outer walls  23 , cylindrical inner walls  24 , and radial walls  25  extending therebetween (see  FIGS. 7 ,  10 ,  11 ,  12 ,  13 ). This shape permits the shells to be stacked vertically in a nested relationship when the individual modular planter sections are to be shipped to a site and then erected in situ in the desired extra-long length. 
         [0025]    The frames  10  are of simple structure having a straightforward rectangular base of two longitudinal legs  11 ,  12  joined to two transverse legs  13 ,  14  by screws  30 . Four vertical posts  15 ,  16 ,  17 ,  18  are fastened to the base by screws  31 . The frame  10  is completed and reinforced by upper longitudinal members  32 ,  33  fastened to posts  15 ,  17  and  16 ,  18  by screws  34 . The legs and posts may be formed of wooden members, rigidified plastic members, or metal members. The posts  15 - 18  are arranged to both support the individual shells  20  and to permit end-to-end abutment of contiguous frames  10  and shells  20 . 
         [0026]    The shells  20  include web portions  36 ,  37  which are fastened to the upper surfaces of the frame  10  by screws  38 ,  39  to complete an individual planter  40  as shown in  FIG. 2 , and comprising the fundamental elements of a module for creating extra-long “macro” linear planters  100  ( FIG. 9 ) of lengths more than several hundred feet, each module comprised of a half-pipe shell  20  supported by a skeletal frame  10 . The short planter  40  of  FIG. 2  is exemplary of the fundamental elements found in the “macro” planter  100  of the invention comprised of a large series of frames  10  and shells  20  juxtaposed end-to-end as shown in  FIGS. 8 and 9 . The planters  40  and  100  are clad, in accordance with the invention, with vertical outer panels  50  of translucent plastic arranged in spaced relation with inner reflective or opaque panels  51  to form a circumscribing light box  53  closed at its top by horizontal translucent panels  52  ( FIG. 5  and  FIG. 9 ). 
         [0027]    More specifically, as shown in  FIG. 4 , upper and lower L-shaped clips  60  are fastened at their distal ends to the frame  10 , the bent ends  61  of the clips engaging and securing the cladding panels  50 ,  51  to the frame  10 . The translucent panels  52  are secured by epoxy cement (not shown) to the upper edges of the panels  50 ,  51 . An LED lighting strip  70  is supported by mounting plates  71  internally of the light box  53  to light the exposed outer cladding panels of the planter. This interior LED lighting which may be multicolored and programmed to change periodically, provides special visual effects as will be appreciated. Moreover, the panels  52  may bear artwork or be stenciled to provide further visual effects and/or messaging for use in advertising applications or in traffic management applications. 
         [0028]    As will be understood, the planters of the invention, whether formed as a single unit such as in  FIGS. 1-5  or multiples ganged together in series such as shown in  FIGS. 8 and 9  are filled with growing medium such as enriched soil  90  ( FIG. 6  and  FIG. 14 ) to support and to nurture growing plants P. 
         [0029]    As a further specific aspect of the invention, the planter shells  20  are provided with a series of drainage ports  80  formed in the ribs  22  above the shell bottom to limit the amounts of water accumulation in the shells when the contained plants are irrigated. The number, location, and size of the ports  80  may be customized to suit the amount of moisture to be retained in the planters which is dictated by the requirements of flora to be grown in a particular planter. Bottom drainage ports  81  are also included as a control of the water accumulation during plant irrigation. While not shown, automatic irrigation piping may be readily incorporated into the macro planters by virtue of the open shells being arranged end-to-end. Water flow in the shells  20  is indicated by arrows in  FIGS. 12 and 13 . 
         [0030]    As a particular advantage of the new planter, the troughs  22  and semi-circular shape thereof promote concentrated and healthy root growth as shown in  FIG. 14 . Moreover, the use of cylindrical half-pipe shells, rather than box-like soil containers, reduces the total weight of loaded planters by approximately one third and reduces the amount of growing medium and irrigation required for the planters which are rectangular parallelpiped in appearance (“coffin”-shaped) but internally semi-cylindrical in soil-holding, plant-retaining configuration. 
         [0031]    As an important feature of the invention, new and improved lighted planters  100  ( FIG. 9 ) of extra-long lengths may be assembled utilizing the fundamental building blocks of semi-cylindrical shells  20 , skeletal parallelpiped frames  10 , and wall panels  50 ,  51  secured to the frames  10  by simple clips  60 . To produce a planter  100  of a length determined by the multiple of the number of shells employed, the shells  20  (supported in frames  10 ) are juxtaposed end-to-end as shown in  FIG. 8 , with congruent gaskets or gasket material  91  sandwiched between contiguous ends of the shells to establish tight joints. Skeletal frames  10  for the shells are formed from the frame elements shown in  FIG. 1 , with the posts, longitudinal, and transverse members specifically arranged to accommodate end-to-end juxtaposition of frames  10  to form a continuous support of the juxtaposed shells  20  therein. The juxtaposed abutted frames are secured to one another by screws or fasteners (not shown) in conventional fashion. The extra-long planters  100  are clad in the manner of the planter of  FIG. 1  with exterior panels  50 ,  51  secured by clips  60  to the frames  10 . With one or more LED strips  70  extending for the length of planter  100 , the resulting visual display of lighted housing for hundreds of feet of plants is spectacular. While primarily intended as a support for a long line of plants, the macro planter  100 , especially when lighted, may be used to create unique advertising or promotional displays when erected on rooftops. Alternatively, the planter units  100  may be used in highly trafficked (vehicular or pedestrian) areas to control flow while providing stunning visual effects, advertising and/or traffic information directions. 
         [0032]    It should be understood, of course, that the specific form of the invention herein illustrated and described is intended to be representative only, as certain changes may be made therein without departing from the clear teachings of the disclosure. Accordingly, reference should be made to the following appended claims in determining the full scope of the invention.
