DETAILED DESCRIPTION

(23) The tables disclosed herein can be used alone, to provide various seating options or to allow the tables to be used in different spaces (e.g., up against a wall, in a corner, or in the open). A table can also be configured to allow for storage of objects under an area of the table that would ordinarily be obstructed by a table leg.

(24) When two or more of the tables are used together, as will be discussed in more detail below, one or more of the legs of the table can be pivoted to maximize the available seating or for other purposes, e.g., for accessibility or for aesthetics.

(25) Referring to FIG. 1, a table 10 includes a table top 12 having an upper surface 14 and a lower surface 16. Generally, both surfaces are substantially planar, exclusive of any surface texture or ornamentation. Table 10 also includes four legs 18, each of which includes a vertical leg portion 20 and a horizontal elongated support arm 22. Each support arm 22 is pivotably mounted to the lower surface 16 at a proximal end 24 and joined to the vertical leg portion 20 at a distal end 26. Each proximal end 24 includes a cylindrical portion 28 at the proximal end 26. A pivoting mechanism, shown in detail in FIGS. 7 and 8 and described below, is disposed in each of the cylindrical portions, allowing the support arm 22 to pivot about an axis A (FIG. 6).

(26) Each support arm 22 is disposed in a plane that is generally parallel to a plane defined by the lower surface, as can be seen in FIG. 6 (planes P1 and P2). Each support arm 22 also includes an upper surface 30 that is configured to contact and support the lower surface 16 of the table top 12.

(27) Each vertical leg portion 20 extends from a proximal end 32 adjacent the lower surface 16 of the table top to a distal end 34 configured to contact a floor surface to support the table top at a predetermined distance from the floor surface. The proximal end of the vertical leg portion is mounted on the distal end of the support arm 22 such that the vertical leg portion pivots with the support arm, changing the orientation of the vertical leg portion relative to the table top when the vertical leg portion is oriented generally perpendicular to the table top (i.e., the leg is not being folded onto the underside of the table top, as is the case in conventional folding tables, but instead its position supporting the table top is being adjusted).

(28) In the example shown in FIGS. 1-3B the orientation of the legs can be adjusted between three predetermined positions and the legs fixed in place in these positions. The legs are independently pivotable, to allow for a large number of possible configurations, of which only three are shown in FIGS. 1, 2 and 3. For the sake of simplicity in the illustrated configurations all of the legs have been pivoted to the same position in FIGS. 1-3. Examples of multi-table configurations in which this is not the case are shown in FIGS. 4 and 5.

(29) The legs may be fixed in the predetermined positions using any desired mechanism. Referring to FIGS. 5 and 6, in the implementation shown in FIGS. 1-3B, the legs are fixed in place by the interaction of a position thumb screw 40 with one of a plurality of threaded inserts 42 positioned in openings 44 in the lower surface 16. If desired, the position of the leg can be easily adjusted simply by lifting the distal end of that leg very slightly off the floor surface, loosening the thumb screw 40 just enough to back it out of the opening 44, pivoting the leg 18 to the desired new position, and advancing the thumb screw 40 into the new opening 44. There is no need to turn the table over or lift the entire table, which is particularly advantageous if the table is large and heavy (for example a large wood dining table). Moreover, pivoting is guided and controlled by the support arm 22 allowing easy location of the thumb screw in the desired opening.

(30) While various types of pivoting mechanisms can be used, an example of a suitable mechanism is shown in FIGS. 6-8. As can be seen in FIG. 6, the mechanism includes a hinge bolt 50 inserted into a countersunk bore 52 in the cylindrical portion 28 and threaded into a threaded insert 54 disposed in an opening 56 in the lower surface 16 of the table top. Referring now to FIGS. 7 and 8, the pivoting mechanism 60 (FIG. 7) also includes, to ensure smooth pivoting, a lock washer 62, a lower washer 64, a bearing sleeve 66, and an upper washer 68.

(31) Referring again to FIGS. 4 and 5, the pivoting legs described above allow multiple tables (e.g., the illustrated tables 10A and 10B) to be configured in a variety of different ways, for example end to end as shown in FIG. 4 or side by side as shown in FIG. 5. The pivoting legs can be adjusted so that the vertical leg portions 20 of the legs are not in the way of people seated at the tables, optimizing the amount of seating space provided by the table arrangement. This can be advantageous for large dinner parties, business meetings, etc., and allows the tables to be easily reconfigured and used separately for smaller groups.

(32) Referring to FIGS. 9-9B, in a table 110 according to an alternative embodiment two legs 118A, 118B can be arranged to pivot about a common pivot axis P. This common-axis pivoting can be accomplished in various ways. In the illustrated implementation, as shown in FIGS. 9A and 9B, the proximal ends of the support arms 122A, 122B include tongues 170, 172 that are configured to fit together as shown in FIG. 9. The tongues 170, 172 include through bores (not shown), and are positioned under a cylindrical element 174 that extends from the lower surface 116 of the table top 112. Cylindrical element 174 includes an opening with a threaded insert (not shown) similar to the opening/insert 54/56 shown in FIG. 6. The remainder of the pivoting mechanism shown in FIG. 7 may be disposed in the aligned bores of tongues 170, 172, or any desired pivoting mechanism may be provided.

(33) Referring now to FIGS. 10-12, in a table 210 according to another embodiment the orientation of the vertical leg portions can be changed by sliding rather than pivoting movement. In this embodiment the legs 218 do not include a support arm. Instead, the proximal end 217 of each leg is generally T-shaped in cross-section, allowing it to be retained in a groove 219 (FIG. 11) that is generally C-shaped provided in a channel element 221 mounted on lower surface 216 of the table top 212. This engagement of the proximal end 217 in the groove 219 allows the leg 218 to slide along the groove 219 when the leg is unweighted by lifting the distal end of the leg slightly off of the floor surface. If desired, the leg can be locked into one of multiple pre-set positions with a push-button telescoping tube lock (also known as a ball catch or button clip), a threaded knob insert, a quick release ball lock pin, or any other desired locking mechanism. Alternatively, the leg can be allowed to slide to any desired position along the groove and held in place simply by the weight of the table.

Other Embodiments

(34) A number of embodiments have been described. Nevertheless, it will be understood that various modifications may be made without departing from the spirit and scope of the disclosure.

(35) For example, while the planar element shown in the figures has completely planar top and bottom surfaces, in some cases ornamental or functional features might be included that would disrupt the surface of the plane. For example, the bottom surface of the table top could be rough hewn wood. The bottom surface need only be sufficiently locally planar to allow pivoting of the legs and the upper surface need only be sufficiently planar to accommodate the intended use of the table.

(36) Additionally, while the tables shown in the drawings are rectangular, the features described herein can also be used with tables having other geometric shapes.

(37) Also, while FIGS. 1-3B show an embodiment in which pivoting legs can be moved between three fixed positions, in other embodiments a greater or smaller number of positions can be used.

(38) To provide additional adjustability, as shown in FIG. 13 a table 310 can include arcuate grooves 331 in which protrusions 333 (of which only one is visible) extending from arms 22 are slidably engaged. The arcuate grooves replace the openings 44 discussed above and allow the legs to be pivoted to any point on the arc of the arcuate groove. Locking mechanisms (not shown) may be provided to fix the position of the legs when a desired positioning is achieved, or the positions may be fixed by the weight of the table.

(39) Moreover, while in the drawings (e.g., FIG. 1) the upper surface 30 of the support member 22 is shown as being in contact with the lower surface 14 of the table top along its entire length in some cases contact may be discontinuous, for example if it is desired that the support member having an aesthetically pleasing shape.

(40) Accordingly, other embodiments are within the scope of the following claims.
