[0078] FIGS. 1 and 2 illustrate a top isometric view and a bottom isometric view, respectively, of a drop deck panel 100. FIGS. 3 through 4E illustrate a top orthogonal view, a bottom orthogonal view, a right orthogonal view, a left orthogonal view, a front orthogonal view, and a back orthogonal view, respectively, of a drop deck panel. In one example embodiment, a drop deck panel 100 is 4 feet along the short axis 122 and 8 feet along the long axis 120. The long axis 120 and the short axis 122 are substantially perpendicular to each other. The top surface of the panel 100 (see FIGS. 1 and 3) includes a plurality of raised surface features 102. In one embodiment, the topmost surface of the raised surface features is approximately 1 / 16-inch above the surface of the panel 100. The raise surface features form channels 110 (see FIG. 5) on the top surface of the panel 100 through which water may traverse, which assists in directing water away from the topmost surface of the panel 100. The raised surface features 102 further avoid any “sink marks” from a mold from interfering with the topmost surface of the panel 100. The bottom surface of panel 100 (see FIGS. 2 and 4) includes a plurality of ribs 104 that correspond to channels 110 on the top surface. The ribs 104 are configured flush with the bottommost surface of the panel 100 such that the ribs 104 contact the ground, which provides more stability when the panel 100 is installed.

[0079] The panel 100 includes a plurality of holes 106 (see FIGS. 3 and 4), residing within the channels 110, through which water may traverse the panel 100. In one example embodiment, the holes 106 are located approximately every 12 inches along the long axis 120 and every 20 inches along the short axis 122. Water may be directed away from the topmost surface of the panel 100, through the channels 110, through the holes 106, and to the ground on which the panel 100 sits. The holes 106 further allow air to traverse through the panel 100 to the ground below, reducing damage to any grass on the ground. The raised surface features 102 may be textured to further reduce the risk of slippage. FIG. 5 illustrates a close-up, top cross-sectional perspective view of the drainage holes 106 of the drop deck panel 100. FIG. 6 illustrates a close-up, bottom perspective view of the drainage holes 106. FIG. 7 illustrates a close-up, top cross-sectional perspective view of a drainage hole 106. The holes 106 may serve the dual purpose of being screw holes. In any of the holes 106, a screw may be inserted to couple the panel 100 to a component beneath the panel 100. For example, the panel 100 may be coupled to a beam 702 of a scaffolding structure (see FIG. 7). The number of holes 106 may be configured such that more holes 106 exist than required to serve as screw holes, thus ensuring that holes 106 will be available to serve as drainage. Optionally, plugs (not shown) may be inserted into one or more holes 106 to prevent walking hazards for high-heeled shoes.

[0080] FIG. 8 illustrates a close-up perspective view of a corner of the drop deck panel 100. In one embodiment, one or more corners of the panel 100 includes a cut-away feature 108, such that, when four panels are coupled corner to corner, the corners of the four panels form an additional drainage hole.

[0081] FIGS. 9 and 10 illustrate a top perspective view and a bottom perspective view, respectively, of a pair of drop deck panels coupled in a top-to-bottom configuration. FIGS. 11 and 12 illustrate close-up, top cross-sectional perspective views of a pair of drop deck panels coupled in a top-to-bottom configuration. In one example embodiment, a pair of drop deck panels 100A-100B may be coupled, or stacked, such that the ribs 104A on the bottom surface of a first panel 100A reside within the channels 110B formed by the raised surface features 102B of a second panel 100B. Although only a pair of panels 100A-100B are shown, additional panels 100 may be coupled / stacked to either panel 100A or 100B. The top-to-bottom configuration of panels 100A-100B allows a set of panels to be transported with less sliding and / or requiring less strapping to hold in place, which provides greater safety in the transport of the panels.

[0082] FIG. 13 illustrates a perspective view of a pair drop deck panels coupled in a bottom-to-bottom configuration. FIG. 14 illustrates a close-up, cross-sectional view of a coupling of a pair of drop deck panels in a bottom-to-bottom. In one embodiment, a pair of drop deck panels 100A-100B may be coupled such that the ribs 104A of a first panel 100A abuts the ribs 104B of a second panel 100B. As shown in FIG. 14, the ribs 100A and 100B are aligned such that one or more of the holes 106A of the first panel 100A abut one or more holes 106B of the second panel 100B. A screw 1402 may be inserted through the holes 106A-106B to couple the first and second panels 100A-100B. When coupled in this manner, the first and second panels 100A-100B provide a thicker and stronger panel. The coupling of the first and second panels 100A-100B also forms an enclosed structure, which may be desirable if the panels are to rest on soft ground, such as grass or sod. Further, plugs (not shown) may be inserted into the holes 106A and 106B, in which screws are not inserted, to prevent water from entering the enclosed structure and / or to prevent walking hazards for high-heeled shoes. Optionally, the panels 100A-100B may also be welded together to fully seal the panel combination.

[0083] A set of drop deck panels may be coupled in a variety of configurations. For example, FIG. 15 illustrates a set of drop deck panels coupled in a checkerboard configuration. FIG. 16 illustrates a set of drop deck panels coupled in a staggered configuration. FIG. 17 illustrates a set of drop deck panels coupled in a hatch pattern.

[0084] FIG. 18 illustrates a close-up view of a lock direction indication. In one embodiment, a lock direction indication 1802 may be included on the top surface of the drop deck panel 100. The lock direction indication 1802 may be placed proximate to one or more of the cam locks (not shown). A cam lock may lock using either a clockwise or counterclockwise turn, depending on the configuration of the cam lock installation. By including the lock direction indication 1802, safety is improved by reducing a risk of a cam lock being turned in the unlock direction when a locking direction is intended.

[0085] FIGS. 19 and 20 illustrate a top perspective view and a side view, respectively, of a drop deck panel transition piece. In one embodiment, the thickness of the drop deck panel 100 is greater than a standard ¾-inch plywood, commonly used in conjunction with a flooring system. To prevent the transition between a ¾-inch plywood and the drop deck panel 100, a transition piece 1902 that includes an inclined surface on at least a portion of the top side of the transition piece 1902 may be coupled to the plywood. The inclined surface includes a higher end that is proximate to the panel 100 and a lower end that is distal from the panel 100. As shown in FIG. 20, an edge of a piece of the plywood (not shown) would reside within the space 2002. The transition piece 1902 would be coupled to the edge of the plywood, such as via screws. The transition piece 1902 includes a cut-away feature 1904 at its bottom side that corresponds to features at an edge of the panel 100. For example, the male portions 2201 of the tongue and groove locking mechanism 2200 (described further below) may reside within the cut-away feature 1904. The transition piece 1902, coupled to the plywood, would be positioned to abut the panel 100 such that a topmost surface of the transition piece 1902 is flush with the top surface of the panel 100. The inclined surface of the transition piece 1902 provides a transition between the top surface of the panel 100 to the top surface of the plywood, thus reducing the risk of a tripping hazard. By use of the transition piece 1902, no modifications to the plywood or the panel 100 is required.

[0086] FIGS. 21A-21G illustrate a cam lock 2100 for coupling a plurality of panels. FIGS. 21A and 21B illustrate top isometric views of a panel 100 that includes a plurality of cam locks 2100. Two cam locks 2100 reside in each of the long sides of the panel 100, while one cam lock 2100 reside in each of the short sides of the panel 100. FIG. 21C illustrates a cross-sectional isometric view of the receptacle portion 2101 of the cam lock 2100. FIG. 21D illustrates a cross-sectional isometric view of a latch portion 2102 of the cam lock 2100. FIG. 21E illustrates an isometric cross-sectional view of the cam lock 2100 in situ. FIG. 21F illustrates a cross-sectional bottom isometric close-up view of a plurality of panels coupled by the cam lock 2100. FIG. 21G illustrates a top isometric cross-sectional close-up view of a plurality of panels coupled by the cam lock 2100. The cam lock 2100 includes a receptacle portion 2101 and a latch portion 2102. The receptacle portion 2101 and the latch portion 2102 are positioned on opposite sides of the panel 100. The receptacle portion 2101 includes a receiver 2104. The latch portion 2102 of the cam lock 2100 includes a latch 2105 that may be rotated by inserting a tool (e.g., hex wrench 2107, see FIG. 21E) into an opening 2106 in the latch portion 2102. The latch 2105 may be rotated to protrude beyond the housing of the latch portion 2102 and engage the receiver 2104 of the receptacle portion 2101, thus placing the cam lock 2100 in a locked position.

[0087] FIGS. 22A-22E illustrate a tongue and groove locking mechanism 2200 for coupling a plurality of panels. FIGS. 22A and 22B illustrate top isometric views of tongue and groove locking mechanisms in a panel 100. FIG. 22C illustrates an isometric close-up view of a female portion 2202 of a tongue and groove locking mechanism 2200. FIG. 22D illustrates an isometric close-up view of a male portion 2201 of a tongue and groove locking mechanism 2200. FIG. 22E illustrates an isometric cross-sectional view of the tongue and groove locking mechanism 2200 with the male and female portions 2201-2202 coupled. As illustrated in FIGS. 22A and 22B, the front side and the right side of the panel 100 includes female portions 2202 of the tongue and groove locking mechanism 2200 and the receptacle portions 2101 of cam locks 2100. The back side and the left side of the panel 100 includes male portions 2201 of the tongue and groove locking mechanism 2200 and the latch portions 2102 of cam locks 2100.

[0088] Referring to FIGS. 21A-21G and FIGS. 22A-22D, the first and second panels 100A and 100B may each be the panel 100. To couple the first panel 100A to the second panel 100B, the male portion 2201 in the first panel 100A is pressed into the female portion 2202 in the second panel 100B, such that the male portion 201 in the first panel 100A resides within the female portion 2202 in the second panel 100B. The cam lock 2100 is then placed into the locked position. To place the cam lock 2100 in a locked position, the latch 2105 of the cam lock 2100 in the first panel 100A is rotated to engage the receiver 2104 of the receptacle portion 2101 in the second panel 100B. The cam lock 2100 in the locked position prevents the decoupling of the panels 100A and 100B due to movements along the axes 120 and 122. The engagement of the male portion 2201 and the female portion 2202 of the tongue and groove locking mechanism 2200 prevents the decoupling of the panels 100A and 100B due to up and down movements of the panels 100A and 100B. Referring to FIG. 22E, when a load is applied to the top surface of the first panel 100A, the first panel 100A moves downward. The downward movement of the first panel 100A is limited by the engagement of the bottom 2206 of the male portion 2201 with the bottom surface 2205 of the female portion 2202. When the load is then removed from the first panel 100A, the first panel 100A moves upward. The upward movement of the first panel 100A is limited by the engagement of the top 2207 of the male portion 2201 with the top surface 2208 of the female portion 2202. Similarly, when a load is applied to the top surface of the second panel 100B, the second panel 100B moves downward. The downward movement of the second panel 100B is limited by the engagement of the top surface 2208 of the female portion 2202 with the top 2207 of the male portion 2201. When the load is then removed from the second panel 100B, the second panel 100B moves upward. The upward movement of the second panel 100B is limited by the engagement of the bottom surface 2205 of the female portion 2202 with the bottom 2206 of the male portion 2201. To decouple the first panel 100A and the second panel 100B, the cam lock 2100 is placed into an unlocked position, where the latch 2105 of the latch portion 2102 in the first panel 100A is rotated to disengage from the receiver 2104 of the receptacle portion 2101 in the second panel 100B. The first and second panels 100A-100B are then separated to decouple the male portion 2201 of the tongue and groove locking mechanism 2200 in the first panel 100A from the female portion 2202 of the tongue and groove locking mechanism 200 in the second panel 100B.
