The backboard 250 is preferably a unitary structure with a top rail 252, a bottom rail 254, a first side rail 256 and a second side rail 258. The backboard 250 also includes a support structure 260 disposed between the rails 252, 254, 256, 258. The support structure 260 desirably has a generally H-shaped configuration with a first vertical rail 262, a second vertical rail 264 and a horizontal rail 266. The backboard 250 desirably includes a plurality of depressions 200 formed in each of the rails 252, 254, 256, 258, 262, 264, 266. In greater detail, as shown in FIG. 8, the top rail 252 may include a plurality of depressions 200 and, as shown in the accompanying drawings, the top rail may include at least four depressions, at least six depressions, at least eight depressions, at least ten depressions, and/or more than ten depressions such as fifteen depressions. The bottom rail 254 may include a plurality of depressions 200 and, as shown in FIG. 8, the bottom rail may include at least four depressions, at least six depressions, at least eight depressions, and/or more than eight depressions, such as ten depressions. The first side rail 256 may include a plurality of depressions 200 and, as shown in FIG. 8, the first side rail may include at least four depressions, at least six depressions, at least eight depressions, and/or more than eight depressions, such as ten depressions. The second side rail 258 may include a plurality of depressions 200 and, as shown in FIG. 8, the second side rail may include at least four depressions, at least six depressions, at least eight depressions, and/or more than eight depressions, such as ten depressions. The first vertical rail 262 of the support structure 260 may include a plurality of depressions 200 and, as shown in FIG. 8, the first vertical rail may include at least four depressions, at least six depressions and/or more than six depressions, such as eight depressions. The second vertical rail 264 of the support structure 260 may include a plurality of depressions 200 and, as shown in FIG. 8, the second vertical rail may include at least four depressions, at least six depressions and/or more than six depressions, such as eight depressions. The horizontal rail 266 of the support structure 260 may include a plurality of depressions 200 and, as shown in FIG. 8, the horizontal rail may include at least four depressions and/or more than four depressions, such as five depressions. As shown in FIG. 8, the depressions 200 in the rails 252, 254, 256, 258, 262, 264, 266 may be disposed in the same direction or in different directions. For example, the depressions 200 in the top rail 252 and bottom rail 254 may be disposed in generally the same direction, such as a generally horizontal direction. The depressions 200 in the first side rail 256 and the second side rail 258 may be disposed in generally the same direction, such as a generally vertical direction. Thus, the depressions in the top rail 252 and the bottom rail 254 may be disposed in a first direction and the depressions in the first side rail 256 and the second side rail 258 may be disposed in a second direction. Therefore, the backboard 250 may include at least eight depressions 200 disposed in a first direction and at least eight depressions disposed in a second direction. As shown in FIG. 8, the depressions in the first direction may be generally perpendicular to the depression in the second direction. Thus, the backboard 250 may include at least eight depressions 200 disposed in a first direction at least eight depressions disposed in a second direction that is generally perpendicular to the first direction. Further, as seen in FIG. 8, the depressions 200 may be generally aligned in rows and columns. For example, the rows of depressions 200 may extend along the top rail 252 and the bottom rail 254, or along the first side rail 256, the second side rail 258 and/or the first vertical rail 262 and the second vertical rail 264. The columns of depressions 200 may extend along the top rail 252 and the bottom rail 254, or along the first side rail 256, the second side rail 258 and/or the first vertical rail 262 and the second vertical rail 264. It will be understood that while the depressions 200 can be formed in any desired portions of the backboard 250, the depressions are preferably formed in substantially all of the structural portions of the backboard.
As discussed above, the backboard 250 may be constructed with an increased number of depressions 200 that are spaced closely together to create a backboard with increased strength and structural integrity. As shown in FIG. 8, the depressions 200 may cover substantially the entire rear surface 268 of the backboard 250. As indicated by the reference number 200, the depressions in the backboard 250 may be similar to the depressions described above in connection with the table 10. For example, as discussed above, the depressions 200 are preferably arranged in a predetermined pattern to create a structure with generally uniform characteristics. Additionally, the depressions 200 preferably have a generally constant and uniform spacing across the surface of the structure. Thus, the depressions are preferably spaced so that the distance between the depressions is minimized, substantially the entire surface is covered with depressions, and the depressions are located in a generally uniform and consistent pattern.
As seen in FIG. 8, which is an exemplary embodiment of a blow-molded structure such as backboard, the depressions 200 are preferably closely spaced to minimize the distance between the depressions. As discussed above, the depressions 200 are preferably integrally formed as part of a unitary, one-piece structure.
As discussed above, the depressions 200 may have a height h generally equal to a thickness t of the table top 12, where the thickness is the distance separating the lower surface 16 and the upper surface 14. The depressions 200 may also have a height h generally equal to a thickness t of the backboard 250, where the thickness is the distance separating the front surface and the rear surface 268 of the backboard. It will be appreciated that the thickness t of the backboard 250 may refer to the width of the backboard.
As shown in FIG. 5 (which is a cross-sectional side view of a blow-molded structure such as a table top or basketball backboard), the depressions 200 are separated by a distance d. The distance d is preferably measured from the center of one depression 200 to the center of another adjacent depression. Desirably, the distance d separating adjacent depressions 200 is generally consistent so that a pattern of depressions with generally uniform and constant spacing is created.
As stated above, the distance d separating the depressions 200 is preferably minimized and the depressions are preferably located in a generally uniform and consistent arrangement so that a lightweight, high-strength structure with relatively uniform properties is created. In particular, the depressions 200 are preferably arranged in a tightly packed array that covers substantially all a surface of a blow-molded structure, such as the rear surface 268 of the backboard 250. For example, in order to create a tightly packed array of depressions 200, the distance d between adjacent depressions is preferably less than or equal to three times the thickness t of the blow-molded structure, such as the backboard 250. In order to create a more tightly packed array of depression 200, the distance d between adjacent depressions is preferably less than or equal to two times the thickness t of the blow-molded structure, such as the backboard 250. The distance d between adjacent depressions 200 may also be equal to or less than the thickness t of the blow-molded structure, such as the backboard 250. Additionally, the distance d between adjacent depressions 200 may be less than or equal to three times the height h of the blow-molded structure, such as the backboard 250. Further, the distance d between adjacent depressions may be two or less times than the height h of the blow-molded structure, such as the backboard 250. Finally, the distance d between adjacent depressions may be equal to or less than the height h of the blow-molded structure, such as the backboard 250.
As shown in FIGS. 5 and 6, the distance d separates the depressions 200. As discussed above, the distance d between the depressions 200 is preferably minimized so that a lightweight, high-strength structure with relatively uniform properties is created. In addition, as discussed above, the blow-molded structures may include an upper or working surface 14 and a lower, mounting or bottom surface 16, such as shown in FIGS. 1-6. The blow-molded structures may also include a front surface 270 and a rear surface 268, such as shown in FIGS. 8 and 9. One of ordinary skill in the art will appreciate that these upper, working, lower, mounting, bottom, front and rear surface may be referred to as first and second surfaces, if desired. Therefore, as discussed above, in order to create a tightly packed array of depressions 200, the distance d between adjacent depressions is preferably less than or equal to three times the distance separating the first surface and the second surface. In addition, as discussed above, in order to create a more tightly packed array of depression 200, the distance d between adjacent depressions is preferably less than or equal to two times the distance separating the first surface and the second surface. Further, the distance d between adjacent depressions 200 may also be equal to or less than the distance separating the first surface and the second surface.
As shown in FIG. 8, the depressions 200 may be disposed in the top rail 252, bottom rail 254, first side rail 256, second side rail 258 and support structure 260. As discussed above, the support structure 260 may include a first vertical rail 262, a second vertical rail 264, and a horizontal rail 266, and the depressions 200 may be disposed in these portions of the support structure 260. Additionally, as shown in FIG. 8, the depressions 200 may have generally the same length and width. Therefore, the depressions 200 may have a generally constant length and width if the depressions have a generally uniform configuration as shown in the drawings. In addition, the accompanying figures illustrate the depressions 200 may be disposed proximate an edge of a table top 12 or backboard 250. As illustrated in FIG. 8, the depressions 200 may be disposed proximate the edge of the backboard and the depressions may be spaced apart from the edge of the backboard by a distance that is generally equal to or less than the length of the depressions. In particular, if the depressions 200 have generally the same length, as illustrated in the figures, then the depressions disposed proximate the edge of the backboard may be spaced apart from the edge by a distance generally equal to or less than an average length of the plurality of depressions.
