DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

(18) The present invention is generally directed towards tables. The principles of the present invention, however, are not limited to tables. It will be understood that, in light of the present disclosure, the tables disclosed herein can be successfully used in connection with other types of furniture and structures.

(19) Additionally, to assist in the description of the tables, words such as top, bottom, front, rear, right and left are used to describe the accompanying figures. It will be appreciated, however, that the tables can be located in a variety of desired positions and the tables can have various suitable shapes, sizes and configurations. A detailed description of exemplary embodiments of the table now follows.

(20) As shown in FIGS. 1-8, an exemplary embodiment of a table 10 includes a table top 12 with an upper surface 14 and a lower surface 16. The upper surface 14 of the table top 12 is preferably generally planar to create a relatively smooth and flat working surface, but the upper surface could also be textured and have other suitable shapes and configurations depending, for example, upon the intended use of the table. The table top 12 may also include an outer edge 18 that is disposed about a perimeter or periphery of the table top. All or a portion of the outer edge 18 of the table top 12 may be beveled, sloped, rounded and the like according to, for example, the intended design and/or aesthetics of the table 10.

(21) The table top 12 may include a lip 20 disposed at least proximate the outer edge 18. The lip 20 preferably extends downwardly beyond the lower surface 16 of the table top 12 and the lip may be aligned with and/or form a part of the outer edge 18. The lip 20 may have a generally U-shaped configuration with an inner portion 22, an outer portion 24 and a lower portion 26. Preferably, the inner portion 22 is disposed towards an interior portion of the table top 12 and the outer portion 24 is disposed towards an outer portion of the table top. In particular, the outer portion 24 of the lip 20 may be generally aligned with the outer edge 18 of the table top 12, but all or a portion of the lip could also be spaced inwardly from the outer edge. The lip 20 may also include a hollow interior portion and the lip may be integrally formed with the table top 12 as part of a unitary, one-piece construction. It will be appreciated, however, the lip 20 does not have to be formed as a unitary component of the table top 12 and the lip is not required.

(22) As shown in the accompanying figures, the table top 12 preferably has a generally round or circular configuration. For example, the table top 12 may have a diameter in the range between about five feet and about six feet. The table top 12 may also be larger and could have a diameter more than six feet, such about seven feet, about eight feet, or more. In addition, the table top 12 may be smaller and could have a diameter less than five feet, such as about four feet, about three feet, or less. One of ordinary skill in the art will appreciate that the table top 12 can be larger or smaller according, for example, to the intended use of the table 10. Additionally, the table top 12 may have other suitable shapes and configurations such as oval, elliptical, rectangular, square and the like.

(23) The table top 12 is preferably constructed from a lightweight material and, more preferably, the table top may be constructed from plastic, such as high density polyethylene. The plastic table top 12 may be desirably formed by a blow-molding process because, for example, it may allow a strong, lightweight, rigid and sturdy table top to be quickly and easily manufactured. Advantageously, the blow-molded plastic table 12 top may be lightweight because it may include a hollow interior portion that is formed during the blow-molding process. It will be appreciated that the hollow interior portion of the table top 12 could be filled, for example, with a material such as foam and the hollow interior portion is not required.

(24) The blow-molded plastic table top 12 may be relatively durable, weather resistant, temperature insensitive, corrosion resistant, rust resistant and long-lasting. One of ordinary skill in the art, however, will appreciate that the table top 12 does not have to be constructed from blow-molded plastic and other suitable materials can be used to construct the table top such as other types of plastics, polymers and synthetic materials. In addition, the table top 12 may be constructed from other materials with desirable characteristics such as wood, metal, fiberglass, ceramics, graphite and the like. Further, other types of processes may be used to construct the table top 12 such as injection molding, rotary molding and the like.

(25) The upper surface 14 of the table top 12 is preferably generally spaced apart from the lower surface 16 by a given distance and these two spaced apart surfaces may help create a rigid and strong table top. Preferably, the upper surface 14 and the lower surface 16 of the table top 12 are separated by a generally constant distance so that the surfaces are generally aligned in parallel planes. The upper surface 14 and the lower surface 16, however, do not have to be spaced apart by a generally constant distance and, in fact, the upper and lower surfaces could be separated by any desired distance.

(26) The table top 12 may also include one or more structures or features that may be sized and configured to increase the strength and rigidity of the table top. For example, the table top 12 may include one or more depressions, which are also known as tack-offs or kiss-offs, that are sized and configured to increase the strength and rigidity of the table top. Advantageously, the depressions may be integrally formed as part of a unitary one-piece table top 12, such as during the blow-molding or other molding processes.

(27) The depressions may be disposed in the lower surface 16 of table top 12 and may be sized and configured to increase the strength and structural integrity of the table top. The depressions may also be sized and configured to help create a table top 12 with more uniform characteristics such as strength, rigidity and surface smoothness. The depressions preferably extend towards the upper surface 14 of the table top 12 and the ends of the depressions may contact or engage an inner portion of the upper surface of the table top. The ends of the depressions may be spaced apart from the inner portion of the upper surface 14 of the table top 12 depending, for example, upon the desired characteristics of the table.

(28) The depressions may cover substantially the entire lower surface 16 of the table top 12, but it will be appreciated the depressions may cover only a portion of the table top. Additionally, it will be appreciated that the depressions could be formed in any desired portion of the table top 12. For example, one or more depressions may be formed in the upper surface 14 of the table top 12 and one or more depressions may be formed in the lower surface 16 of the table top, and these opposing depressions may be generally aligned. At least a portion of these opposing depressions may contact or engage each other, but the opposing depressions do not have to touch or engage. One or more depressions may also be formed in other portions of the table top 12 such as the lip 20.

(29) The depressions are preferably arranged into a predetermined pattern or array, which may help increase the strength and structural integrity of the table top 12. In addition, the depressions may be closely spaced such that the distance between adjacent depressions is minimized. If the distance between adjacent depressions is minimized, for example, the unsupported areas of the upper surface 14 of the table top 12 may also be minimized. This may increase the smoothness of the upper surface 14 of the table top 12. In addition, minimizing the distance between adjacent depressions may increase the structural integrity and strength of the table top 12. The closely spaced depressions may also help create a table top 12 with more uniform characteristics. Thus, the closely spaced depressions may create a table top 12 with greater strength, improved structural integrity and an upper surface 14 with increased smoothness.

(30) In addition, the depressions are preferably arranged in a predetermined pattern with a generally constant and uniform spacing so that the table top 12 has generally uniform characteristics. In particular, the depressions are preferably arranged into a generally uniform pattern across at least a majority of the lower surface 16 of the table top 12 so the strength, structural integrity and/or other characteristics of the table top are generally uniform. Thus, the table top 12 may have fewer, if any, weak or unsupported portions which may decrease the strength and structural integrity of the table top. The depressions may also be used to create a table top 12 with generally uniform characteristics. It will be appreciated that the depressions may also have a non-uniform spacing depending, for example, upon various features that are formed in the table top 12 or upon the intended use of the table 10. It may be desirable, however, for these various features that are formed in the table top 12 to be sized and configured such that they do not significantly disturb or disrupt the generally uniform pattern of depressions. Additional information about exemplary depressions that may be used in connection with the table top 12 are disclosed in U.S. Pat. Nos. 7,069,865; 7,160,215; 7,171,910; 7,331,297; 7,476,164; 7,634,970; 7,644,667; 7,972,225 and 8,006,630, which are incorporated by reference in their entireties.

(31) Advantageously, the increased structural integrity and strength of the table top 12 may allow the outer wall thickness of the table top to be decreased, which may allow the table top to be constructed with less material. For example, if the table top 12 is constructed from blow-molded plastic and the outer wall thickness is reduced, then less plastic may be used to construct the table top. Because less plastic may be used to construct the table top 12, the cost of the table 10 may be decreased. In addition, the table top 12 may cool more quickly during the manufacturing process because of the decreased outer wall thickness and/or smaller amount of plastic used to construct the table top. This may allow the table top 12 to be removed from the manufacturing mold more quickly and it may allow the table top to be removed at a higher temperature because the thinner outer wall may dissipate heat more rapidly. Significantly, manufacturing efficiency may be increased because the time required to construct the table top 12 may be decreased. While the table top 12 may include one or more depressions, which may be integrally formed with the table top during the blow-molding process, it will be appreciated that depressions are not required and the table top does not have to be manufactured from blow-molded plastic.

(32) As seen in FIGS. 1-2 and 4-8, the table 10 may include one or more supports, such as leg assemblies 28, 30, which may be sized and configured to support the table top 12 above a surface. The leg assemblies 28, 30 may include legs or supports 32, 34, 36, 38, and the legs may be connected by one or more connecting members. For example, a first connecting member 40 may connect the legs 32, 34 and a second connecting member 42 may connect the legs 36, 38. In addition, one or more cross members may interconnect the legs 32, 34, 36, 38. For example, a first cross member 44 may interconnect the legs 32, 34 and a second cross member 46 may interconnect the legs 36, 38. Advantageously, the connecting members 40, 42 and/or cross members 44, 46 may help create a sturdy and secure table 10.

(33) The leg assemblies 28, 30 may be movable between an extended or use position and a collapsed or storage position relative to the table top 12, which may facilitate moving and/or storage of the table 10. In particular, the legs 32, 34, 36, 38 may be disposed at least proximate the lower surface 16 of the table top 12 in the collapsed position. The legs 32, 34, 36, 38 may extend outwardly from the table top 12 in the use position. It will be appreciated the legs assemblies 28, 30; the legs 32, 34, 36, 38; the connecting members 40, 42; and the cross members 44, 46 may have other suitable shapes, sizes, configurations and arrangements depending, for example, upon the intended use of the table 10. It will also be appreciated that the table 10 may have any suitable number of leg assemblies, legs, connecting members and/or cross members depending, for example, upon the type and configuration of the table 10.

(34) The table 10 may further include a frame 48 that is connected to the table top 12. As seen in FIGS. 2 and 4, the frame 48 may connected to the lower surface 16 of the table top 12 and the frame may include one or more rails, channels, support members and the like. For example, the frame 48 may include rails, such as side rails 50, 52, and the side rails may be separated by a distance. Specifically, the side rails 50, 52 may be disposed near opposing portions of the table top 12 and the side rails may be at least partially disposed proximate the outer edge 18. In particular, the ends of the side rails 50, 52 may be disposed at least proximate the outer edge 18 while the center portion of the side rails may be spaced apart from the outer edge by a gap or distance. The side rails 50, 52 may have a length that is generally equal to or greater than a majority of a length, radius and/or diameter of the table top 12. The side rails 50, 52 may also have a length significantly less than a length, radius and/or diameter of the table top 12.

(35) The leg assemblies 28, 30 may be connected to the side rails 50, 52 of the frame 48. In particular, the connecting members 40, 42 of the leg assemblies 28, 30 may be connected to the side rails 50, 52 of the frame 48. Preferably, the connecting members 40, 42 are pivotally connected to the side rails 50, 52 to allow the leg assemblies 28, 30 to be moved between the extended and collapsed positions. The leg assemblies 28, 30 may be connected to opposing ends the side rails 50, 52 and the leg assemblies may be generally disposed between the side rails. Advantageously, when the leg assemblies 28, 30 are in the collapsed positions, the leg assemblies may be generally disposed between and coplanar with the side rails 50, 52.

(36) As seen in FIGS. 2 and 4, the ends of the connecting members 40, 42 may be disposed within or extend through openings in the side rails 50, 52 of the frame 48, which may allow the leg assemblies 28, 30 to be pivotally connected to the table top 12. The connecting members 40, 42 may also be connected to the frame 48 in other suitable configurations and arrangements, such as shown in U.S. Pat. No. 7,100,518, which is incorporated by reference in its entirety. The connecting members 40, 42 may also be connected to other portions of the frame 48, the table top 12 and/or the table 10.

(37) The leg assemblies 28, 30 may be offset and that may allow longer legs 32, 34, 36, 38 to be used in connection with the table 10. The offset configuration may also allow the same leg assemblies 28, 30 to be used on either side of the table 10, which may facilitate manufacturing and/or assembly of the table. The offset leg assemblies 28, 30 may further allow the legs 32, 34, 36, 38 to be disposed in an adjacent configuration when the legs are in the collapsed position.

(38) The frame 48 may be used to offset the leg assemblies 28, 30. For instance, the side rails 50, 52 may include angled portions 54, 56 that allow the leg assemblies 28, 30 to be offset. As best seen in FIG. 2, the angled portions 54, 56 may be disposed between two generally straight sections of the side rails 50, 52, and the angled portions may be disposed towards an end of the side rails. In particular, the angled portions 54, 56 may be disposed between a first generally straight section that has a length generally equal to or greater than a length of an adjacent leg and a second generally straight section that has a shorter length. The angled portions 54, 56 preferably offset the first and second sections of the side rails 50, 52 by an amount slightly larger than the width or diameter of the legs 32, 34, 36, 38. Thus, the legs 32, 34 of the leg assembly 28 may not be aligned with the legs 36, 38 of the leg assembly 30. Additionally, when the leg assemblies 28, 30 are in the collapsed position, this may allow the leg 32 to be disposed adjacent to the leg 36, the leg 34 to be disposed adjacent to the leg 38, the legs to be disposed at least proximate the lower surface 16 of the table top 12, and the legs to be generally aligned in the same plane.

(39) As mentioned above, the lip 20 may be disposed about the outer periphery of the table top 12 and the lip may be generally aligned with the outer edge 18 of the table top. In addition, the lip 20 may have a circular or ring-shaped configuration if the table 10 has a round table top 12. As best seen in FIGS. 1 and 2, the table top 12 may include one or more handles 58 which may be openings or recesses disposed in the lip 20. Advantageously, the handles 58 may facilitate moving and carrying of the table 10. In addition, the handles 58 may facilitate separating the tables 10 in a stacked and/or nested configuration, which is described in more detail below.

(40) The table 10 may include four exemplary handles 58 that are spaced equidistant about the perimeter of the table top 12. For example, two handles 58 may be disposed proximate a midpoint of the side rails 50, 52 and two handles may be disposed proximate a midpoint of the connecting members 40, 42. In this configuration, the handles 58 are spaced as far apart as possible from the ends of the side rails 50, 52, and the ends of the connecting members 40, 42. In addition, the handles are spaced as far apart as possible from the body of the side rails 50, 52 and the body of the connecting members 40, 42. While the handles 58 may be symmetrically disposed about the perimeter 18 of the table top 12, the table 10 could include any suitable number of handles in any desired locations.

(41) While the handles 58 shown in the accompanying figures illustrate the handles extending the entire width of the lip 20, it will be understood the handles may be disposed in only a portion of the lip. For example, the handles 58 may be formed only in the outer portion 24 of the lip 20 and not the inner portion 22. In addition, the handles 58 may be formed in the inner portion 22, the outer portion 24 and the lower portion 26 of the lip 20, but the handles may have a height significantly less than the height of the lip. In particular, the handles 58 may have a height less than about fifty percent (50%) of a height of the lip 20, such as in the range of about thirty to about forty (30-40%) of the height of the lip. The handles 58 could also have a smaller height such as about twenty-five (25%) or less of the height of the lip, but the handles could also be larger with a height in the range between about sixty percent (60%), seventy percent (70%) or more.

(42) The table 10 may also include a central cross member 60 that spans at least a portion of the table top 12. The cross member 60 is preferably centrally located and at least partially disposed between the table top 12 and the leg assemblies 28, 30 and/or the frame 48. For example, as shown in FIG. 2, the cross member 60 may consist of a rod or tube and a portion of the cross member may be disposed in a recess in the lower surface 16 of the table top 12. In addition, the cross member 60 may be disposed or sandwiched between the connecting members 40, 42 of the leg assemblies 28, 30 and the table top 12. The cross member 60 may be designed to allow the leg assemblies 28, 30 to freely move between the collapsed and extended positions, and the cross member may contact the connecting members 40, 42, when a load or force is applied to the table top 12. The cross member 60 may also be designed to provide increased support for a center portion of the table top 12. It will be appreciated that the cross members 60 may have other suitable configurations and any number of cross members may be utilized depending, for example, upon the configuration and/or intended use of the table 10. It will also be appreciated that the cross member 60 is not required.

(43) The table 10 is preferably sized and configured to be stacked with one or more additional tables. In particular, the table 10 is preferably sized and configured to be stacked with other tables having the same general size, shape, configuration and arrangement. Additionally, the table 10 is preferably sized and configured to nest with other similar tables to reduce the height of the stacked tables, which may allow the tables to be shipped, stored and transported in a smaller area. This may result in significant cost savings to the manufacturer, for example, because less storage space may be required and a substantial reduction in transportation costs may be achieved.

(44) The lip 20 is preferably sized and configured to facilitate stacking and nesting of the table 10. For example, as best seen in FIGS. 9 and 12, the inner portion 22 of the lip 20 may be disposed at an angle in the range between about 60 and about 75 relative to the lower portion 26 of the lip. The angle could also be larger, such as between about 80 and about 85, or smaller, such as between about 45 and about 55, if desired. The outer portion 24 of the lip 20 may be generally vertically disposed and it may form at least a portion of the outer edge 18 of the table top 12.

(45) The inner and outer portions 22, 24 of the lip 20 may be separated by an average distance, which may be referred to as a thickness or width of the lip. The lip 20 may have a thickness in the range between about three-quarters (0.75) inch and about one and one-half (1.5) inches. In particular, the lip 20 may have a thickness of about one and one-quarter (1.25) inches. The lip 20 could also have a smaller width, such as about one-half (0.5 inches) or less, or a larger width, such as about two (2.0) inches or more. It will be appreciated that the size of the lip 20 may depend upon the size and/or intended use of the table 10.

(46) The lower portion 26 of the lip 20 may have a generally planar configuration that is generally parallel to the upper and/or lower surfaces 14, 16 of the table top 12. The lower portion 26 of the lip may also include a contact surface 62 that is sized and configured to contact an adjacent table when the tables are nested together. In particular, the contact surface 62 may be sized and configured to contact an upper surface of the table top of the adjacent table when the tables are nested together. The contact surface 62 may be an interior portion of the lower portion 26 of the lip 20. If the table top 12 has a circular or round configuration, then the contact surface 62 may have a generally ring-shaped configuration and the contact surface may be disposed in a single plane. The contact surface 62 may be a generally smooth surface that is at least substantially free from projections to match the generally flat, level upper surface of the adjacent, nested table. It will be appreciated that the contact surface 62 may also have other configurations and arrangements depending, for example, upon the shape, contour or form of the adjacent, nested table.

(47) In greater detail, the contact surface 62 may be a continuous surface that is at least substantially unbroken or uninterrupted, except for the optional handles 58. That is, the contact surface 62 may not include any openings or breaks other than for the handles 58. Further, the contact surface 62 may form at least a majority and perhaps substantially the entire lower portion 26 of the lip 20. Additionally, the contact surface 62 may have a rather large surface area and may be disposed at least proximate the circumference or outer perimeter of the table top 12. In particular, the contact surface 62 may have a ring-shaped configuration with an outer circumference that is generally equal to or slightly less than a circumference of the table top 12. Significantly, this large contact surface 62 may help prevent the adjacent, stacked table from being damaged. In addition, if the contact surface 62 is disposed about at least a majority of the table top 12, the contact surface may have a large surface area and that may allow the nested tables to support a significant amount of weight or force without being damaged because the load may be spread out over a large area. Further, if the contact surface 62 is disposed towards an inner portion of the lower portion 26 of the lip 20, this may facilitate contact with the upper surface of the adjacent, stacked table. It will be understood that the contact surface 62 may also be formed by other suitable portions of the lip 20 and/or table top 12.

(48) The lower portion 26 of the lip 20 may also include an engaging portion 64 which may extend outwardly from the lower portion of the lip. In particular, the engaging portion 64 may extend downwardly from an outer portion of the lower portion 26 of the lip 20. In addition, the engaging portion 64 may be disposed adjacent to the contact surface 62. For example, if the contact surface 62 is formed by an inner portion of the lower portion 26 of the lip 20, the engaging portion 64 may be formed by an outer portion of the lower portion of the lip. Advantageously, if the contact surface 62 and engaging portion 64 are disposed next to each other, then multiple adjacent surfaces may contact or abut when the tables 10 are nested together.

(49) In greater detail, the engaging portion 64 may be disposed about the outer edge 18 of the table top 12. In particular, the engaging portion 64 may include an outer portion 66 that is generally aligned with the outer portion 24 of the lip 20. While the engaging portion 64 may be disposed at least proximate the outer periphery of the lip 20 and/or the table top 12, the engaging portion may also be spaced inwardly. Advantageously, the engaging portion 64 may be a continuous structure that is disposed about the entire table top 12. In greater detail, as seen in FIG. 2, the engaging portion 64 may have a ring-shaped configuration and may be disposed about the entire perimeter of the table top 12 other than the optional handles 58. If desired, the engaging portion 64 may also be disposed in the optional handles 58. If the engaging portion 64 is at least substantially uninterrupted, then it may provide a large contact area with an adjacent, stacked table. The engaging portion 64 could also be a contiguous structure with one or more portions that abut or disposed proximate to each other. It will be appreciated that the engaging portion 64 could further include one or more portions that are spaced apart depending, for example, upon the configuration of the table top 12.

(50) The engaging portion 64 may have a generally constant size, such as height and width, and it may have a generally U-shaped configuration. For example, the engaging portion 64 may include an inner portion 68 disposed towards the contact surface 62 and a lower portion 70 disposed between the inner portion and the outer portion 66. If the table top 12 has a round configuration and four handles 58 spaced equidistant, the engaging portion 64 may be divided into four quadrants that have generally the same size, shape, configuration and arrangement. Significantly, this may facilitate stacking and nesting of the tables 10 regardless of the orientation of the tables. That is, the tables 10 may be stacked and nested as long as the upper and lower portions of the table are aligned, and the tables may not need any other alignment.

(51) The engaging portion 64 may be integrally formed with the lip 20 and/or the table top 12 as part of a unitary, one-piece construction. The engaging portion 64 may include a hollow interior portion that is in direct communication with the hollow interior portion of the lip 20 and/or the table top 12. The engaging portion 64 may also be formed from compression molded plastic. For example, if the table top 12 is formed from blow-molded plastic, then the engaging portion 64 may be compression molded during the blow-molding process. The compression molded engaging portion 64 may be formed by having the inner portion 68 and the outer portion 66 directly touch or contact so there is no gap or space between the inner and outer portions. Because the compression molded engaging portion 64 may have a double-wall thickness, it may create a stronger, more rigid and/or more impact resistant structure. The compression molded engaging portion 64 may be relatively thin because there is little or no space between the inner and outer portions 66, 68 of the engaging portion 64.

(52) As mentioned above, the engaging portion 64 may have a generally uniform size and configuration. In addition, the engaging portion 64 may be directly adjacent to the contact surface 62. For example, the engaging portion 64 may have a width between about one-eighth (0.125) inch and about one-half (0.5) inch. In particular, the engaging portion 64 may have a width between about two-tenths (0.2) inch and about one-quarter (0.25) inch. The engaging portion 64 may have a height between about one-tenth (0.1) inch and about one-half (0.5) inch. Preferably, the engaging portion 64 has a height of about one-eighth (0.125) inch. Advantageously, the engaging portion 64 may be integrally formed with the table top 12 as part of a unitary, one-piece construction. In addition, the relatively small size of the engaging portion 64 may allow it to be created during the manufacturing process. For instance, the engaging portion 72 could be a protrusion that is formed during a molding process.

(53) The contact surface 62 and the engaging portion 64 may have a generally constant size and configuration. Advantageously, the constant size of the engaging portion 64 may facilitate stacking and alignment of the tables 10. In addition, the constant size of the engaging portion 64 may allow the tables 10 to be stacked in different arrangements and orientations. The constant size of the contact surface 62 and the engaging portion 64 may allow weight or forces to be more evenly applied to stacked, nested tables. One of ordinary skill in the art will appreciate, after reviewing the disclosure herein, the contact surface 62 and engaging portion 64 may have other shapes, sizes, configurations and arrangements depending, for example, upon the type or intended use of the table 10.

(54) The table top 12 may include a receiving or nesting portion 72 that is sized and configured to facilitate nesting of the tables. The receiving portion 72 may be at least partially disposed about the perimeter 18 and/or the upper surface 14 of the table top 12. Desirably, the receiving portion 72 may be disposed below a plane aligned with the upper surface 14 of the table top 12. The receiving portion 72 is preferably sized and configured to receive the engaging portion 64 of an adjacent, nested table. The receiving portion 72 may be integrally formed with the table top 12 as part of a unitary, one-piece construction during the molding process if, for example, the table top is constructed from molded plastic.

(55) In greater detail, the receiving portion 72 may be disposed at least proximate the intersection of the upper surface 14 and the outer edge or perimeter 18. The receiving portion 72 may have a generally L-shaped configuration that is open on two sides, which may facilitate alignment and/or nesting of the tables 10. As shown in the accompanying figures, the receiving portion 72 may be a groove or channel with a height preferably between about one-tenth (0.1) inch and about one-half (0.5) inch, such as about one-eighth (0.125) inch, and a width that may be larger than the height by a factor such as two, three or more. For example, the width may be approximately two times the height such that, in this exemplary embodiment, if the height is about one-eighth (0.125) inch, then the width may be about one-quarter (0.25) inch. The height and the width may also be approximately the same. For instance, if the height is about one-eighth (0.125) or about one-quarter (0.25) inches, then the width may also be about one-eighth (0.125) or about one-quarter (0.25) inch. It will also be appreciated that the width may be smaller than the height. Thus, for example, if the height is about four-tenths (0.4) inch, then the width may be about three-tenths (0.3) inches or less. It will be understood that the height and the width may vary depending, for example, upon the intended use of the table 10.

(56) The exemplary dimensions given above may be used in connection with a table top 12 that has a lip 20 with a height of about one and one-half (1.5) inches. It will be understood that the contact surface 62, the engaging portion 64 and/or the receiving portion 72 could also larger or smaller depending, for example, upon the size, shape, configuration or arrangement of the table top 12. It will also be understood that the table top 12, along with one or more of its various components and features, may have other suitable sizes, shapes, configurations and arrangements depending, for example, upon the intended use of the table 10.

(57) As discussed above, the receiving portion 72 may be sized and configured to receive the engaging portion 64. In particular, the inner portion 68 of the engaging portion 64 may contact a sidewall 74 of the receiving portion 72 and/or the lower portion 70 of the engaging portion may contact a lower wall 76 of the receiving portion. For example, the inner portion 68 of the engaging portion 64 may have a height substantially equal to the height of the receiving portion 72 and the lower portion 70 of the engaging portion may have a width substantially equal to the width of the receiving portion. Advantageously, because the receiving portion 72 may be a strong and sturdy portion of the table top 12, the lower wall 76 may be able to support a relatively large amount of force or weight. In addition, the inner portion 68 of the engaging portion 64 may contact the sidewall 74 of the receiving portion 72 to help align and/or keep the tables 10 in the nested configuration. While the receiving portion 72 may be sized and configured to receive the engaging portion 64 of an adjacent, stacked table and the receiving portion may be disposed about the entire perimeter 18 of the table top 12, the receiving portion can also have other appropriate shapes, sizes, configurations and arrangements depending, for example, upon the engaging portion and/or the intended use of the table 10.

(58) Advantageously, the nested tables may have multiple contact surfaces or areas. In addition, the contact areas and surfaces may be at least substantially continuous or uninterrupted, which may allow forces to be more evenly distributed. For example, the lower portion 70 of the engaging portion 64 may contact or abut the lower wall 76 of the receiving portion 72 of the adjacent, stacked table. The inner portion 68 of the engaging portion 64 may also contact or abut the sidewall 74 of the receiving portion 72 of the adjacent, stacked table. Additionally, the contact surface 62 may contact or abut the upper surface 14 of the adjacent, stacked table. The multiple contact areas may create multiple load bearing surfaces that allow a load or force to be shared or distributed over a larger area, which may permit the table 10 to support more weight and may help prevent damage to the table top 12.

(59) Additionally, the engaging portion 64 and the receiving portion 72 may facilitate nesting of the tables 10, which may significantly reduce the height of a plurality of stacked tables. The reduction in height of the stacked tables 10 may be particularly advantageous when manufacturing, shipping, storing and displaying of the tables. Further, while the table top 12 may have the same general size, configuration and appearance as a conventional table top, the table top 12 may allow two or more stacked tables to be nested together.

(60) For instance, the table top 12 may have a height measured from the upper surface 14 to the lower portion 70 of the engaging portion 64 that is about one and five-eighths (1.625) inches. Because the engaging portion 64 may be disposed in a receiving portion 72 of an adjacent, nested table 10, the table may only have a height of about one and one-half (1.5) inches in the stacked configuration. This may result in a decrease in height of a table 10 in the stacked configuration of more than seven percent (7%), which may allow seven percent more tables to be loaded into a conventional shipping container. This may also allow the same number of tables 10 to be disposed in an area that is seven percent smaller than a conventional table with the same size and shape.

(61) Further, the contact surface 62, the engaging portion 64 and the receiving portion 72 may be integrally formed with table top 12 as part of a unitary, one-piece structure. Because these features may be integrally formed as part of the table top 12, the manufacturing process may be expedited. These features, however, are not required and the features do not have to be integrally formed in the table top as part of a unitary, one-piece structure.

(62) As seen in FIGS. 2, 7 and 8, the table may also include one or more braces 80 used in connection with the leg assemblies 28, 30. In particular, a brace 80 may be used in connection with each of the leg 32, 34, 36, 38. For example, one end of the brace 80 may be attached to the frame 48, such as the side rail 50 or 52, and the other end of the brace may be attached to one of the legs 32, 34, 36, 38. The brace 80 may be used to secure the legs 32, 34, 36, 38 in the extended position.

(63) In greater detail, as seen in FIGS. 13-15, the brace 80 may include an elongated slot 82 with a body 84 and a receiving portion 86. An engaging member, such as a pin 88, may be connected to one of the legs 32, 34, 36, 38 and disposed within the slot 82. In particular, the pin 88 may have a generally cylindrical body 90 that is disposed within the slot 82 and an enlarged end or head 92. The brace 80 may also include a biasing member 94, such as a spring, which may be used to bias the brace into a desired position. For example, the biasing member 94 may be used to bias the brace 80 into a locked position, which may be used to lock the leg 32, 34, 36, 38 in the extended position. The brace 80 may be movable between a first position, such as shown in FIGS. 13 and 15, and a second position, such as shown in FIG. 14.

(64) In further detail, the brace 80 may include an elongated body 96 with a first end 98 that is pivotally connected to a side rail 50, 52 of the frame 48, and a second end 100. The biasing member 94 may be located towards the second end 100 of the brace 80 and the biasing member may include an engagement surface 102 that is sized and configured to contact the pin 88. One end of the biasing member 94 may be attached to the elongated body 96 of the brace 80 and the other end may be disposed in a groove or channel 104 in the second end 100 of the brace 80. The biasing member 94 may be used to bias the pin 88 into the receiving portion 84 of the elongated slot 82, which may selectively lock the leg 32, 34, 36, 38 in the extended position. In particular, the biasing member 94 may exert a force to maintain the pin 88 in the receiving portion 86. To unlock the brace 80, a force sufficient to overcome the biasing member 94 may be applied to allow the pin 88 to move out of the receiving portion 86 of the elongated slot 82.

(65) Advantageously, the brace 80 may automatically lock the legs 32, 34, 36, 38 in the extended position. Thus, for instance, as the pin 88 moves within the slot 82 towards the receiving portion 86, the pin may cause the biasing member 94 to move or rotate. Once the pin 88 is in the receiving portion 86, the biasing member 94 may move or rotate to bias the pin into the receiving portion. The pin 8 may be moved from the receiving portion 86 by moving the biasing member 94 and/or overcoming the biasing force. Significantly, the braces 80 can be made very strong because the brace itself does not have to deflect to disengage from the locked position. In contrast, the brace 80 may simply rotate into the desired position. Additionally, the brace 80 may be engaged in the locked position because the biasing member 94 may push, move or rotate the brace relative to the pin 88. It will be appreciated that this can also be accomplished by the biasing member 94 loading the brace 80 relative to the leg 32, 34, 36, 38 and/or the table top 12. If desired, the locking portion of the brace 80 could be a secondary part that rotates into position after the pin 88 slides past it.

(66) The brace 80 and the biasing member 94 are preferably constructed from relatively strong and durable materials such as steel. It will be appreciated that the brace 80 and the biasing member 94 may also be constructed from other metals and materials with suitable characteristics, including materials such as plastics, composites and the like. Advantageously, because the biasing member 94 may help absorb forces applied to the brace 90, and the biasing member may help reduce the chances that the brace will be damaged by inadvertent impacts and/or through repeated use.

(67) An exemplary use of the brace 80 is illustrated in FIGS. 13-15. For example, as seen in FIG. 13, the brace 80 is in a first position with the pin 88 in the receiving portion 86 and the biasing member 94 biasing the pin into the receiving portion. In this configuration, the leg 32, 34, 36, 38 may be locked in an extended position. As seen in FIG. 14, when the pin 88 is disposed at the end of the slot 82 and aligned with the receiving portion 86, the brace 80 may rotate to dispose the pin within the receiving portion. As seen in FIG. 15, the brace 80 may rotate as the pin 88 moves within the slot 82 as the leg 32, 34, 36, 38 is moved between the extended and collapsed positions. Advantageously, the brace 80 may securely maintain the leg 32, 34, 36, 38 in the locked position and the brace may be easily locked and unlocked by simply rotating the brace. One of ordinary skill in the art will appreciate after reviewing the disclosure herein that the brace 80 may have other suitable shapes, sizes, configurations and arrangements depending, for example, upon the type and/or intended use of the table 10.

(68) As seen in FIG. 16, the table top 12 may include a plurality of strengthening members 110, which may be integrally formed with the table top as part of a unitary, one-piece construction. The strengthening members 110 may comprise outwardly extending portions, such as ribs or protrusions, that extend outwardly from the lower surface of the table top and/or inwardly extending portions, such as grooves or channels, which extend inwardly from the lower surface 16 of the table top 12. The strengthening members 110 may be sized and configured to strengthen and/or increase the rigidity of specific portions of the table top 12. In particular, the strengthening members 110 may be used to strength a portion of the table top that extends outwardly or beyond the frame 48 and/or the leg assemblies 28, 30.

(69) As shown in the accompanying figures, the table top 12 may include a plurality of strengthening members 110 and the strengthening members may be disposed on opposing sides of the table top. The strengthening members 110 disposed on opposing sides may be aligned and have generally the same length. In addition, all of the strengthening members 110 may have generally the same length but it will be appreciated that the strengthening members 110 may have any suitable length.

(70) The strengthening members 110 may be sized, shaped, configured and/or arranged to increase the strength, rigidity, structural integrity and/or torsion resistance of the table top 12. For example, the strengthening members 110 may have opposing walls 112, 114 and the opposing walls may increase the strength, rigidity, structural integrity and/or torsion resistance of the table top 12.

(71) The strengthening members 110 disposed on both sides of a structural component such as the connecting members 40, 42 of the leg assemblies 28, 30. In particular, the strengthening members 110 may extend from the lip 20 to the other side of the connecting member 40, 42. Additionally, the ends of the strengthening members 110 may be disposed proximate a portion of the table top 12 that is not directly supported by the frame 48. For example, the ends of the strengthening members 110 may be disposed proximate the outer edge 18 of the table top 12. In particular, a first end of the strengthening members 110 may be disposed proximate the outer edge 18 of the table top 12, and the strengthening members 110 may be generally spaced apart an equal distance. Advantageously, the strengthening members 110 may increase the strength, stiffness, rigidity and/or structural integrity proximate the structural support members and the outer edge 18 of the table top 12. This may prevent, for example, the outer edge 18 of the table top 12 from rotating or moving downwardly relative to the connecting members 40, 42.

(72) The strengthening members 110 may also be disposed between the frame 48 and the outer edge 18 of the table top 12. For example, a plurality of strengthening members 110 may be aligned in generally parallel planes and disposed at a right angle relative to the side rails 50, 52 of the frame 48. The strengthening members 110 may be sized and configured to prevent the portion of the table top 12 extending outwardly from the frame 48 from bending if a hinge point is generally aligned with the edge of the frame.

(73) A plurality of strengthening members 110 may be used and the strengthening members may be disposed in different portions of the table top 12 and/or have different configurations. For example, as seen in FIG. 16, a first set of strengthening members 110 may be generally aligned on opposing sides of a first portion of the table top 12 and a second set of strengthening members may be generally aligned on opposing sides of a second portion of the table top. Thus, the first and second sets of strengthening members may be disposed at an angle, such as 90. In addition, the first and second sets of strengthening members 110 may have different shapes, sizes, configurations and arrangements. For example, the first set of strengthening members 110 may be disposed on both sides of the connecting members 40, 42 of the leg assemblies 28, 30. On the other hand, the second set of strengthening members 110 may be disposed between the side rails 50, 52 of the frame 48 and the outer edge 18 of the table top 12. Thus, the second set of strengthening members 110 may have a shorter length than the first set of strengthening members. The second set of strengthening members 110, however, may have larger width than the width of the first set of strengthening members. In addition, the second set of strengthening members 110 may include an engagement surface that engages the side rails 50, 52 and this may help prevent undesired movement of the frame 48. One of ordinary skill in the art will appreciate after reviewing the disclosure herein that the strengthening members 110 may have different shapes, sizes, configurations and arrangements depending, for example, upon the location of the strengthening member.

(74) One of ordinary skill in the art may appreciate after reviewing this disclosure that the tables disclosed herein may have a number of different aspects, features, characteristics and configurations. The tables may also have other suitable aspects, features, characteristics and configurations such as disclosed in Assignee's U.S. Pat.

(75) Although this invention has been described in terms of certain preferred embodiments, other embodiments apparent to those of ordinary skill in the art are also within the scope of this invention. Accordingly, the scope of the invention is intended to be defined only by the claims which follow.
