Floating grid arrangement to support and position decorative elements

Abstract

A plastic grid or framework arrangement is used to support and position a series of bowls that hold flower arrangements, candles, letters, and other decorative elements. This grid is deployable in water fountains, indoor and outdoor pools, and other small bodies of water during festive occasions or for longer term decorative display. A special feature of this invention is that the grid itself does not float and is positioned below the surface of the water, and thus is not readily visible. Buoyancy is provided at the hubs that form nodes in the grid. The hubs also support floating bowls containing various decorative elements. The resulting effect is that the various decorative elements appear to be floating on the surface while the sub-surface grid structure maintains their relative positioning, keeping the bowls from clumping together at the edges or in the corners of the pool or fountain. The framework can take the form of a grid or ring or other shapes and can be assembled quickly from a kit of components and can be easily dis-assembled and stored for future use.

DETAILED DESCRIPTION OF THE INVENTION

(22) During the course of this disclosure like numbers will be used to identify like elements according the different views of the invention.

(23) FIGS. 1A-1C show a triangular grid framework for supporting decorative flower holder bowls 18 using hubs 12 that have six spoke engaging pockets 32 according to the preferred embodiment 10 of the invention. The bowls 18 support flowers 16, or candles, or other decorative objects. Spokes 14 connect to the hubs 12 in a series of repeating patterns suggestive of triangles.

(24) FIGS. 2A-2C show an alternative framework arranged in the form of a ring 20.

(25) FIGS. 3A-3E illustrate details of the six pocket hub 12 and further indicating how the spoke retention spring clips 34 are inserted into and permanently attached in each of the hub pocket 44. Each hub 12 includes a top side 24, a base 26, a sidewall 28 and a hollow central aperture 30. Six slots 32 are located evenly spaced around the sidewall 28. Six springy clips 34, described in detail in FIGS. 17A-17E, are insertable in the pockets 44 as seen in FIGS. 3E and 3D. The clips 34 include a flat first arm section 36, a flat bottom section 38 and a second opposing arm section 40. Second arm section 40 includes a convex bump 42 that selectively engages the detent 60 on the spoke end cap 22 shown in further detail in FIGS. 7A-7F. Each of the pockets 44 includes an aperture 46 for framing the protruding bump 42 which in turn is engages with the detent 60 on the end cap 22. The top 24 of the hub 12 includes a circumferential flat flange portion 48 and a downward side panel 50 that depends therefrom. The six pockets 44 on the hub 12 are spaces 60 degrees apart and, accordingly, can be used to form triangular grid frameworks as shown in FIGS. 1A-1C or the circular framework of FIGS. 2A-2C.

(26) FIGS. 4A-4C illustrate a square grid framework 52 which can be formed with hubs 54 which only have four pockets or slots 54. Details of a four pocket hub 54 are shown in FIGS. 5A-5F. It is similar in construction to the six pocket hub 12 except that it has only four pockets 44 evenly spaced 90 degrees apart.

(27) FIGS. 6A and 6B illustrates the manner in which the spoke ends 22 slides into slots 32 then engage the retention spring 34 in the pockets 44 of a four pocket hub 52. As shown in FIGS. 7A-7F each spoke end cap 22 includes a top, head section 56, a pin-like portion 58 and a concave detent 60 for selectively engaging the bump 42 on the retention spring 34. A spoke receiving pocket 62 is located in the head 56 of the spoke end cap 22. Downward pressure on the end cap head 56, as seen in FIG. 6A, forces the pin section 58 into the pocket 32 until the pin 58 is completely inserted into the pocket 32 and is held in that position by the engagement of convex bump 42 with concave detent 60. Disassembly is accomplished by pulling up on the spoke cap head 56 until the force is sufficient to case the bump 42 to disengage from the detent 60.

(28) FIGS. 8A-8C illustrates how a decorative element support bowl is attached to a hub 54 and how the spokes 14 radiate from the hub 54. Also shown is a bowl 18 including a float chamber 64 located in the center of the bowl. The bowl 18 also locks the spoke ends 22 in position in pockets 32 of hubs 54. The basic frame including the hub 54 and spokes 14 are intended to remain just below the waterline and are not readily seen. The float chamber 64 located in the center of the bowl 18 and in conjunction with the buoyancy of the bowl 18 itself causes the apparatus to float in such a manner that only the bowl 18 is visible above the waterline.

(29) FIGS. 9A-9C illustrate the hub 54 and spoke frame arrangement of FIGS. 8A-8C with the decorative bowl 18 replaced by a separate float element 65 visible above the hub. There are circumstances where it may be desirable not to have a decorative element support bowl 18 at a hub node but need to have the rest of the framework in place and in a balanced position just below the waterline. In this embodiment the float 65 alone locks the end caps 22 in position in pockets 32 of hub 54.

(30) FIGS. 10A-10F illustrates details of a bowl subassembly 18 having a chamber 64 located in the center thereof and also illustrates the location of four dogleg tabs 66 for engaging via rotating motion the circumferential flat flange portions 48 of the four spoke hub 54.

(31) FIGS. 11A-11E illustrates another embodiment of the decorative bowl 72 in which the bottom of the float is formed by the bottom of the bowl 18.

(32) FIGS. 12A-12F show different views of a float subassembly 65. Float 65 includes dogleg tabs 66 for engaging that flange portions 48 of the four spoke hub 54.

(33) FIGS. 13A-13E illustrates the base 80 of a float and FIGS. 14A-14E illustrate the top 82 which mates with base 80 to form float 65 shown in FIG. 12F. The top 82 of the independent, standalone float 65 is also the same as the top 82 of the float chamber 64 in bowl 18 and can be welded or bonded by conventional means to base 80 or the bottom of bowl 18. The seal or bond is hermetic so the bowl 18 does sink or fill with water from below.

(34) It is clear from the above that the float can either be stand alone and separate as in embodiment 65 or can be integrated into the structure of the bowl 18 itself where the bottom 64 of the bowl 72 forms the bottom of the integrated float as seen in FIGS. 11A-11E.

(35) A typical straight spoke 14 is shown in FIGS. 15A-15C. Spoke 14 has an hour glass-like shape and includes a top rib 84, and intermediate connecting section 86 and a bottom rib 88. The shape is the inverse of the shape of the opening 62 in the end cap 22 so that the two mate and stay mated due to the force of friction or by means of thermal or adhesive bonding.

(36) FIGS. 16A-16E show a typical spoke 14 with a pair of end caps 22 attached.

(37) As previously described, FIGS. 17A-17E illustrate the U-shaped locking leaf-type retention spring 34 including the convex bump 42 which is received in the hub pockets 44 and hold the end caps 22 of the spokes 14 in properly assembled position.

(38) FIGS. 18A-18C and 21A-21C illustrate a ring embodiment of the invention in which vertical extenders 94 can be used to raise the height of the decorative bowl 18 substantially above the height of the water surface. Horizontal extenders 96 can also be used to extend the framework and the invention in a plane horizontal to the water surface and the plane of the rest of the framework. Curved spokes 92 are used to connect the hubs 54 together to form a relatively smooth ring-like structure. FIGS. 19A-19D illustrate the alternative embodiment in which the spokes 92 are curved and FIGS. 20A-20D illustrate the manner in which the curved spoke 92 of FIGS. 19A-19D engages a four pocket hub 54.

(39) The invention is typically used in the following manner. First, the user determines the size and shape of the framework array and the number and type of decorative items based on the size and shape of body of water and the specific objectives of the display. Second, using the kit of components, the grid is assembled next to the body of water by snapping the spokes 14 into the hubs 12 or hubs 54. Third, the spokes 14 are than locked into place using either a standalone float subassembly 65 or a bowl 18. Fourth, the decorative elements 16 are attached to or contained in the bowls 18. Additional bowls 18 can be attached to the spokes 14 in between hubs 12 if required. As the array is assembled, it can be slid into the water. The array can also be assembled in the water.

(40) If required, additional spokes 14 can be added on the outside of the array in order to locate the decorative elements 16 in bowls 18 away from the edge of the pool or fountain. In an open body of water, anchors can be attached to the array in order to keep it in place.

(41) When no longer in use the decorative array 10, 20, 52, 90 and 98 can easily be removed from the water and disassembled for storage and future use.

(42) The invention has several advantages over the prior art, namely:

(43) A. The grid is formed using plastic materials with a specific gravity greater than 1.0. These materials can be transparent or colored to match the bottom of the pool.

(44) B. The spokes 14 can be formed in various lengths in order to provide maximum flexibility in the configuration of the array. The spokes have end fittings or caps 22 that are permanently attached. These caps 22 enable quick attachment to the hubs 12, 54 in such a way as to stabilize the grid framework during assembly.

(45) C. The spokes 14 snap into the hubs 12, 54 from above and are retained by spring clips 34 pre-assembled into the hubs 12, 54. The spokes 14 are further locked into position when the float subassembly 65 or a bowl 18 is locked into place on the top of the hub 12. The bowls 18 will hold the decorative elements 16 and the floats 65 can be locked into place on top of the hubs 12, 54 where no bowls are required.

(46) D. It is possible to attach bowls 18, with decorative items 16 in them, to the spokes 14 in between the connecting hubs 12.

(47) E. The floats 65 and the bowls 18 provide the buoyancy to keep the grid from sinking too far below the surface of the water.

(48) F. The size and configuration of the grid is quite variable according to the number of hubs 12, 54 and lengths of spokes 14 and 92.

(49) G. Hubs 12 with six (6) evenly spaced slots 32 will produce a hexagonal array. Hubs 54 with four (4) evenly spaced slots 32 to hold spokes 12 will produce a rectangular array.

(50) H. Curved spokes 92 will produce a circular array. The radius of curvature will define the overall size of this array.

(51) I. Vertical extension fittings 94 can be attached to bowls 18 to provide a platform for decorative arrangements at various heights above the surface of the water.

(52) J. Once the array is constructed with the spokes 14, 92 locked into place in the hubs 12, 54 the whole grid can be maneuvered easily. This allows for construction of the grid on land and so it can to be easily slid into the water for final positioning.

(53) K. If required the grid can be easily modified once it has been deployed in the water.

(54) L. The locking mechanism that keeps the elements of the array in place is unique and easy to use. In the case of a bowl 18 and hub 54, the lower protruding portion 64 acts as a pilot to guide into the slotted cylindrical opening 30 after the spoke caps have been inserted into pockets 32 and held in place by springs 34. Once the base of float 64 of bowl 18 is fully seated, the bowl is rotated about 60 so that the dog legged tabs 66 engage the underside of top flange 48 and are held in place by friction and/or the natural springiness of the plastic compartments. Additional security can be obtained by adding a small rib or bump (not shown) to the underside of flange 48 so the tabs 66 don't back out. The locking with a standalone float 65 is accomplished in exactly the same way, namely, the base 80 is inserted in the slotted cylindrical opening 30 and then rotated until the dog legged tabs 66 fully engage the underside of the top flange 48.

(55) While the invention has been described with reference to a preferred embodiment thereof and several alternative embodiments, it will be appreciated by those of ordinary skill in the art that various modifications can be made to the structure and form of the invention without departing from the spirit and scope of the invention as a whole.
