Alignment of the flat surfaces increases sliding resistance of the connector plate, thereby enhancing stability of a structure utilizing an embodiment of the present disclosure.

(17) Embodiments of the present disclosure include a notch in a section of a rib portion of the protrusion. Embodiments of the present disclosure have a plurality of spike apertures through a planar surface of the connector plate. The spike apertures may be configured to receive a plurality of spikes, which may be barbed spikes. Embodiments of the present disclosure include barbed spikes configured to attach to a connector plate at a plurality of spike apertures. Embodiments of the present disclosure may be modified to increase the number of protrusions extending from the connector plate. Embodiments of the present disclosure allow a user of the connector plate to insert additional protrusions as needed. Embodiments of the present disclosure provide greater holding strength and stability. Embodiments of the present disclosure are configurable such that additional gripping protrusions may be added to increase holding stability.

(18) FIG. 1 is a top isometric view of an exemplary embodiment of the present disclosure. Connector plate 10 is shown as planar structure 20 substantially rectangular in shape, having a front edge 50, a back edge 60 substantially parallel to front edge 50, a first side edge 70 substantially perpendicular to front edge 50 and back edge 60, and a second side edge 80 substantially parallel to first side edge 70 and substantially perpendicular to front edge 50 and back edge 60. Top surface 30 is shown with a first top protrusion 90 and a second top protrusion 100.

(19) Both first top protrusion 90 and second top protrusion 100 have a flat surface portion 110 and a rib portion 120. Flat surface portion 110 is substantially shaped as an isosceles triangle having a base attached to top surface 30 and two equal sides converging in a point extending vertically from top surface 30 such that a planar surface of flat surface portion 110 is substantially perpendicular to a planar surface of the top surface 30. The base of flat surface portion 110 is substantially parallel to back edge 60. Though described herein as triangular, flat surface portion 110 is not limited to any specific shape or embodiment.

(20) Rib portion 120 is substantially shaped as a right triangle having a first leg attached to flat surface portion 110 and a second portion attached to the top surface 30. Rib portion 120 is substantially perpendicular to flat surface portion 110. As shown, rib portion 120 extends from a center of the base of flat surface portion 110 on a front edge side of flat surface 110. Rib portion 120 may incorporate a notch 115 at or near top surface 30 as show in FIGS. 7C and 7D. Notch 115 may be configured such that a point 117 is formed in rib portion 120. When a bag is placed upon rib portion 120, notch 115 grabs into the bag at point 117 providing additional grip and stability. A back edge side of flat surface portion 110 has no rib attached thereto. See, e.g., FIG. 2. The configuration of flat surface portion 110 and rib portion 120 shown in the Figures provides a top protrusion having a flat surface substantially parallel to and facing back edge 60 perpendicular to the planar surface of top surface 30. See, e.g., FIG. 4. Opposite the flat surface, the rib portion provides stability to flat surface portion 110. Though described herein as triangular, rib portion 120 is not limited to any specific shape or embodiment.

(21) The example embodiments in FIGS. 3 and 4, show bottom portion 40 having first and second bottom protrusions 130 and 140. Both first bottom protrusion 130 and second bottom protrusion 140 have a flat surface portion 150 and a rib portion 160. Flat surface portion 150 is substantially shaped as an isosceles triangle having a base attached to bottom surface 40 and two equal sides converging in a point extending vertically below bottom surface 40 such that a planar surface of flat surface portion 150 is substantially perpendicular to a planar surface of the bottom surface 40. The base of flat surface portion 150 is substantially parallel to front edge 50. Though described herein as triangular, flat surface portion 150 is not limited to any specific shape or embodiment.

(22) Rib portion 160 is substantially shaped as a right triangle having a first leg attached to flat surface portion 150 and a second portion attached to the bottom surface 40. Rib portion 160 is substantially perpendicular to flat surface portion 150. As shown, rib portion 160 extends from a center of the base of flat surface portion 150 on a back edge side of flat surface 150. Rib portion 160 may incorporate a notch 155 at or near bottom surface 40 as show in FIGS. 7C and 7D. Notch 155 may be configured such that a point 157 is formed in rib portion 160. When a bag is placed upon rib portion 160, notch 155 grabs into the bag at point 157 providing additional grip and stability. A front edge side of flat surface portion 150 has no rib attached thereto. See, e.g., FIG. 4. The configuration of flat surface portion 150 and rib portion 160 shown in the Figures provides a protrusion having a flat surface substantially parallel to and facing front edge 50 perpendicular to the planar surface of bottom surface 40. See, e.g., FIG. 4. Opposite the flat surface, the rib portion provides stability to flat surface portion 150. Though described herein as triangular, rib portion 160 is not limited to any specific shape or embodiment.

(23) In certain embodiments of the present disclosure, first and second top protrusions 90 and 100 may be aligned with first and second bottom protrusions 130 and 140 such that flat surface portion 110 and flat surface portion 150 are offset. See, e.g., FIG. 4. In other embodiments of the present disclosure, first and second top protrusions 90 and 100 may be aligned with first and second bottom protrusions 130 and 140 such that flat surface portion 110 and flat surface portion 150 are aligned. See, e.g., FIGS. 7C and 7D. Flat surface portion 110 and flat surface portion 150 may be a single piece of material partially passed through an aperture in planar surface 20. In exemplary embodiments of the present disclosure, rib portions 120 and 160 may include extensions 205 configured to be secured into apertures in planar structure 20. See, e.g., FIG. 7D.

(24) FIGS. 5 and 6 show embodiments of the present disclosure installed on wall units. As shown, connector plate 10 is aligned such that front edge 50 is substantially parallel to a front edge of the wall units and back edge 60 is substantially parallel to a back edge of the wall units. FIG. 5 shows embodiments installed on a top surface of the wall units, which may be a first row of a wall or structure. As shown, in alignment, the flat surface of top protrusions 90 and 100 face the back edge of the wall units. FIG. 6 further shows that the flat surfaces of bottom protrusions 130 and 140 face the front edge of the wall units. Having the flat surfaces of the top protrusions face the back edge and the flat surfaces of the bottom protrusions face the front edge provides substantial improved stability and slide resistance over traditional connector units. Under typical conditions, lateral pressures apply a horizontal force pushing bags forward tending to slide higher bags forward over surfaces of lower bags. The present invention provides flat surfaces directly opposing the forces applied by the lateral pressures rather than an angular surface thereby maximizing resistance to the forces. Accordingly, the present invention substantially increases stability in the wall or structure.

(25) FIGS. 7 and 7E show an exemplary embodiment of the present disclosure having a plurality of spike apertures 210 configured to receive and secure a plurality of spikes 300. Spike apertures 210 include a substantially circular center portion 220 and first and second extensions 230 and 240 extending towards first side edge 70 and second side edge 80, respectively. See, e.g., FIG. 7A. Although shown with first and second extensions 230 and 240 aligned towards first and second side edges 70 and 80, additional extensions may be included and the extensions may have different alignments. Spike aperture 210 may include a plurality of locking apertures 250 placed around center portion 220. See, e.g., FIG. 7A. The plurality of locking apertures 250 may be configured to receive a plurality of locking extensions 305 of spike 300. See, e.g., FIG. 9.

(26) Embodiments of the present disclosure may incorporate a plurality of spikes 300. As shown in FIG. 8, spike 300 has a base 310, which may be substantially rectangular, configured to pass through spike aperture 210. Spike extension 350 extends vertically above base 310 and forms spike protrusion 340, which may be a barbed structure of overlapped conical forms (see, e.g., FIG. 8) or other barbed formations. Spike extension 350 may have a total length of approximately 1 inch and may be approximately inch in diameter. Spike extension 350 includes first and second wings 320 and 330 that extend horizontally from spike extension 350 substantially parallel to base 310. First and second wings 320 and 330 may be configured such that first wing 320 extends in a same direction as a first side 315 of base 310 and second wing 330 extends in a same direction as second side 317 of base 310. Base 310 may include a plurality of locking extensions 305. See, e.g., FIG. 9.

(27) In embodiments of the present disclosure, spike 300 is configured such that base 310 may be passed through spike aperture 210 when first side 315 of base 310 is aligned with first extension 230 and second side 317 of base 310 is aligned with second extension 240. Spike 300 may be passed through spike aperture 210 until all of base 310 is out of plane with planar structure 20 but before first and second wings 320 and 330 are in plane with planar structure 20. Spike 300 may then be rotated within spike aperture 210 such that a portion of planar structure 20 lies between base 310 and first and second wings 320 and 330. In certain embodiments, spike 300 may be rotated until locking extensions 305 engage locking apertures 250, locking spike 300 into place inside spike aperture 210.

(28) Although shown with four spike apertures 210, more or less spike apertures may be incorporated into the connector plate. The plurality of spike apertures 210 allow a plurality of spikes 300 to be installed therein. A user may install spikes 300 in each of the spike apertures 210, none of the spike apertures 210, or any combination in between. Spikes 300 may be added to a connector plate as needed to increase holding stability. Embodiments of the present disclosure incorporating a plurality of spike apertures 210 allow a user to configure the connector plates as needed thereby providing flexibility and increased stability where needed without incorporating additional materials/cost when not needed.

(29) Embodiments of the present disclosure may be constructed in various parts; or, alternatively, embodiments may be formed as a single piece. Embodiments may be formed from any suitable material, including non-corrodible metals, plastics or other polymers. Embodiments may be formed from carbon fibers which may provide increased strength and resistance to various destructive elements that the connector may be subjected to such as salt water. Though shown as substantially rectangular, embodiments of the connector plate may be of various shapes. Connector plates may be dimensioned such that first and second bottom protrusions may protrude into adjacent bags when installed.

(30) Embodiments of the present invention include methods of constructing retaining walls, containment systems, levies and/or similar structures with units and connectors. The units may be bags, which may be soil bags or sand bags. The connectors may be connector plates having first and second top protrusions on a top surface of the connector and first and second bottom protrusions on a bottom surface of the connector. First and second top protrusions may have flat surfaces facing a back edge of the connector and rib portions opposite the flat surfaces. First and second bottom protrusions may have flat surfaces facing a front edge of the connector and rib portions opposite the flat surfaces. Bags may be laid adjacent to one another to form a first row of a wall or structure. The connectors may then be placed on top surfaces of the bags of the first row such that one of the first and second bottom protrusions protrudes into each of two adjacent bags. A second row of bags may be added such that a bag covers a connector with the first and second top protrusions protrude into a bottom surface of the bag. This procedure may be repeated until a desired height of the structure is achieved. Alternate configurations and/or arrangement may be employed when connecting units to create a structure or wall.

(31) Embodiments of the present invention include a system of retaining soil, water, or other substances behind a structure. In certain embodiments a system of preventing erosion is provided. In certain embodiments, a system of erecting a retaining structure is provided incorporating interconnecting members having flat surfaces opposing horizontal forces from lateral pressures of a retained substance.
