5 Claims, 5 Drawing Figures OUTDOOR GROUND TILE This invention relates to outdoor ground tile and more particularly to a ground tile of hollow type construction that will anchor to a ground surface.
Up to the presenttime, outdoor ground tile or block used for walks, patios and the like have been generally made of concrete rather than plastic for several reasons. For example, there is the initial higher cost of plastic that dictates a hollow rather than solid plastic tile or block that will have sufficient load bearing abil-' ity and is mass producible. Furthermore, the weight of a concrete tile or block is normally sufficient to hold it in place on the ground but the same surface area tile in plastic would be too light to have such inherent ability. While a plastic tile should have some way of being anchored to the ground the anchoring arrangement should not however add substantial height to the tiles for minimum stacking and packaging height.
The outdoor ground tile according to the present invention meets all the requirements for plastic construction noted above and comprises a load bearing portion having load bearing walls depending downwardly and about the periphery thereof to provide for peripheral ground support thereof. In addition, reinforcing ribs depend downwardly from the underneath side of the load bearing portion and join at their ends with the sides to both reinforce and provide ground support to the load bearing portion. Anchor pins are formed integral with and depend downwardly from both the underneath side and the ribs and separate ground anchors are provided that have a tight fit with the anchor pins and also a tight slot fit with the ribs. The structural outlines of the tile and anchor pins are very simple and renders these parts easily mass producible by injection molding.
An object of the present invention is to provide a new and improved ground tile.
Another object is to provide an outdoor ground tile having a new and improved anchor arrangement for anchoring to a ground surface.
Another object is to provide an outdoor ground tile of hollow design with integral ribs that both reinforce and provide ground support and separate anchors that secure to both the ribs and anchor pins which are formed integral with the ribs. r
Another object is to provide an injection moldable plastic outdoor groundtile that on an underneath side has reinforcingribs and anchor pins integral therewith that add little overall height to the tile and. together with the ribs have separate ground anchors press fit thereto.
The present invention further" resides in various novel constructions and arrangement of parts, and further objects, novel characteristics and advantages of the present invention will be apparent to those skilled in the art to which it relates and from the following detailed description of the illustrated embodiment thereof made with reference to the accompanying drawing forming a part of this specification and in which similar reference numerals or characters are employed to designate corresponding parts throughout the several views, and in which FIG. 1 is a perspective view of a grouping of outdoor ground tiles according to the present invention anchored to a ground surface.
FIG. 2 is an enlarged view of one of the tiles and an attached anchor taken along the line 22 in FIG. 1.
FIG. 3 is an enlarged perspective view of the underneath side of one of the tiles in FIG. 1 without anchors.
FIG. 4'is a perspective view of one of the anchors.
FIG. 5 is a partial perspective view of the underneath side of one of the tiles in FIG. 1 showing an anchor arranged for assembly therewith.
Referring to FIG. 1, there is shown a grouping of outdoor tiles according to the present invention anchored to a ground surface 11. The tiles 10 which may also be described as blocks are for outdoor use to form walkways, patios, borders and the like. The thin section structural design of the tiles 10 whose details will now be described permits them to be readily made of a tough plastic such as polyethylene by injection molding and to be competitive with tiles or blocks of the same size made of cast material such as concrete. In the embodimentshown the tiles 10 which are formed in one piece have a square load bearing portion of thin section 12 with a decorative top side 14 and an underneath side 16 as shown in FIGS. 1 and 2. Side walls 18 depend downwardly from and extend about the entire periphery of the load bearing portion 12 to provide peripheral ground support therefor as shown in FIG. 2. In addition, a pair of thin section reinforcing ribs 20 depend from the underneath side 16, intersect each other at midpoints and attheir opposite ends join with the side walls 18 at the corners as best shown in FIG. 3. The ribs 20 in addition to reinforcing the load bearing portion 12 are thesame height as the side walls 18 and provide ground support along their length to the load bearing portion. Further ground support of the load bearing portion 12 is provided by a plurality of slender legs 22 that are circular in cross-section and depend from the underneath side 16in the areas between the ribs 20 and the side walls 18 as shown in FIG. 3. The legs 22 are preferably the same height as the side walls l8and ribs 20 to provide the additional ground support. Furthermore, the legs 22 because of their slender size .can by building up ground surface inside the side walls 18 serve to penetrate into this ground buildup to provide anchoring of the tile in addition to the primary anchoring structure now to be described. It is also contemplated that the legs 22may be made longer for better anchoring. i
The tiles 10 are primarily'anchored to the ground surface by means of'anchor pins 24 that depend downwardly from both the underneath side 16 and each rib portion intermediate the intersection of the ribs 20 and each rib end at a corner of the tile as shown in FIGS. 2, 3 and 5. The pins 24 have a circular cross-section with a thickness substantially greater than that of the ribs 20 and for the greater part of their height are integral with the ribs with the result that they are very rigid parts of the tile as best shown in FIG. 5. Preferably, the anchor pins 24 are located near the corners of the tile to obtain a spread-out anchoring arrangement which has been found to give optimum anchoring.
Anchoring of the tile 10 to the ground surface is provided by separate anchors 26 shown in FIGS. 2, 4 and 5. The anchors 26 at their upper end have a cylindrical portion having a hole 28 that tightly receives the full height of the anchor pins 24 and also a radial cross-slot 30 that intersects the hole 28 and tightly receives the full height of the ribs 20 as best shown in FIGS. 2 and 5. The anchors 26 at their lower end have a pointed tip 32 with a fluted portion 34 that increases in crosssectional area away from the point terminating in a transverse shoulder 35 that is substantially below the bottom of the ribs 20 and side walls 18 and thus below the normal ground surface when fully implanted as shown in FIG. 2. This anchor shape has been found to provide easy ground penetration and then firm resistance to both lateral and upward movement. The tile is anchored to the ground surface by press fitting the anchors 26 to the pins 24 and ribs 20, positioning the tile in the desired location and then applying force on the top side 14 such as stepping theron.
The structure of the tile 10 is ideally suited for injection molding in one piece of a tough plastic such as polyethylene. For this purpose the side walls 18, ribs 20, support legs 22, and anchor pins 24 all have tapers in the same direction away from the underneath side 16 as best shown in FIG. 2. Furthermore the anchors 26 are similarly made of plastic by injection molding with their hole 28 and cross-slot 30 having a taper. With such tapering there is an added structural benefit in that the anchors 26 then have a taper fit with both the anchor pins 24 and ribs 20.
To exemplify the extent of rigidity possible with the thin wall tile structure according to the above teaching it was found that for a top side of 12 inches by 12 inches a very rigid structure suitable for hard outdoor load bearing usage as walkways, patios and the like was obtained where the thickness of the legs 22 was about three thirty-seconds inch, the thickness of the load bearing portion 12, side walls 18 and ribs waw about one sixteenth inch and the height of the side walls 18 and ribs 20 was about one-half inch. Further more, very adequate and rigid anchoring was provided with a tile of this size by the anchoring pins having a diameter of about three sixteenth inch and the anchors 26 being 2 inches long with the fluted portion 34 about l- /4inches and the shoulder 35 about one-fourth inch below the ribs and side walls and thus the ground surface.
While a rectangular shaped tile has been illustrated, it will be appreciated that the tile according to the present invention may for decorative purposes have other shapes with more or less sides including a round form in which case there would only be one side wall.
Although the illustrated embodiment of the present invention has been described in great detail, it should be apparent that certain modifications, changes, and adaptations may be made in the illustrated embodiment, and that it is intended to cover all such modifications, changes and adaptations which come within the spirit of the present invention.
