Expandable table

Abstract

An expandable table comprises first and second table surfaces connected by a first hinge at their adjoining short sides. First and second legs are fixed to an underside of the first table surface to support the first table surface. A third leg is fixed to an end of a slidable bar or mechanism wherein the slidable bar or mechanism is installed on an underside of the first table surface, wherein the slidable bar or mechanism is configured to be slid out from under the first table surface wherein the third leg provides support for the second table surface when the second table surface is unfolded and wherein the slidable bar or mechanism is configured to be slid under the first table surface wherein the third leg rests adjacent to the first leg when the second table surface is folded to lie on top of the first table surface.

DETAILED DESCRIPTION

(11) The expandable table of the present disclosure will allow classrooms to be used for many different teaching styles. The table, in a preferred embodiment, will allow for four students, for example, to sit on one side facing the front of the room in a lecture configuration. The table then transforms to a table that can sit preferably four students, two on each side facing one another in a collaboration configuration. The table also provides the additional feature of acting as a mobile whiteboard. It will be understood that the table could be designed to fit two students, six students, or more, and that illustrations showing a table for four students do not limit the disclosure to a table for four students.

(12) The expandable table of the present disclosure can be used in business training rooms, co-working spaces, restaurants, conference rooms, and meeting spaces as well as classrooms. FIG. 1 illustrates the expandable table of the present disclosure in a lecture configuration. FIG. 1A illustrates one leg style and FIG. 1B illustrates an alternate leg style. Leg style can vary based on design and use of the table and the specific leg style can be changed to suit customer aesthetic desires, including any other leg style not illustrated.

(13) For example, the table 10 may be 8 long and 2 wide. The table 10 folds to 4 long by 3 wide, for example, as shown in FIG. 6 to allow for collaboration. The book style fold, as shown in FIG. 2, allows for full use of the table in both forms. The sliding third leg 22 is key to making this design work well. When the table is in the small collaboration style configuration shown in FIG. 6, the leg 22 easily stows next to the other leg 18. The speed with which this table can be transformed is also key. The ease of use allows the table to be changed quickly by one person.

(14) The expandable table of the disclosure, in a preferred embodiment, allows for a table to transform between a long lecture style table with four seats 30 on one side, as illustrated in FIG. 7, and then folded into a shorter table, as illustrated in FIG. 8, for collaboration with two seats 30 on each of two opposing sides, four seats in total. It will be understood that other sizes are anticipated, such as a long table for six students that is folded into a table for three students on each side, for example. FIGS. 2 through 5 illustrate the conversion of the lecture style table to the collaboration style table. The Table 10 consists of two separate tabletop sections 12 and 14 that are approximately 4 feet long, for example, and vary in depth from 18 to 30 wide, depending on customer preference. Each section is connected with a hinge 40, as illustrated in FIG. 11, on the short side that allows one piece to fold on top of the other, making the table half as long. Hinge 40 is an example of one possible type of hinge. Other hinge types may be used, especially a hinge that would be flush with the top of the table.

(15) Also attached to one side 14 of the long length is an optional 8-12 wide piece 16 that will flip down on hinge 42 to make the table size 8-12 wider. This extra piece can only be flipped up in the shorter collaborative configuration, as shown in FIGS. 5 and 6. The additional fold down piece 16 to widen the table for use in the collaboration configuration can also be used as a modesty panel in school applications, as shown in FIGS. 1A and 1B, but only on one half of the table.

(16) The table 10 has three legs 18, 20, 22 that allow for this unique configuration. Two of the legs, 18 and 20, are fixed to the stationary side 12 of the table. As shown in FIGS. 12A and 12B (in examples of two possible leg styles shown in FIGS. 1A and 1B, respectively), there is a full extension slide 44 on the underside of the stationary side of the table. The third leg 22 is attached to this slide 44. This feature allows for the third leg to slide out or in depending on the desired configuration of the table. FIG. 12A illustrates an example of the slide 44 attached vertically to leg attachment plates 54 where a channel 46 for slidable bar 24 is vertically oriented. FIG. 12B illustrates an example of slide 44 attached to the underside of the table 12 where a channel 46 for receiving slidable bar 24 is horizontally oriented. Other slidable mechanisms can be used.

(17) Additionally, as shown in FIGS. 9 and 10, the table can be rotated 90 degrees on the vertical axis for nesting storage and to function as a mobile whiteboard. Several tables can be stored with tabletops and legs touching each other in a compact space. FIG. 13 illustrates legs 18 and 20 attached to plates 54. Plates 54 are hinged 52 to plates 50 attached to the underside of the table 12. The hinges 52 allow the table top to be rotated 90 degrees for nesting storage or to function as a mobile whiteboard. The whiteboard surface would be on the underside 15 of table surface 14. A whiteboard surface might also be advantageous in the collaboration configuration where the underside 15 of the table surface 14 is facing up.

(18) The present disclosure has described an expandable table having the following features:

(19) 1) book style folding motion with hinge attached to the short side of the table

(20) 2) sliding leg that allows a third leg to easily slide in and out

(21) 3) table configuration can be changed by one person

(22) 4) table configuration can be changed in seconds

(23) 5) additional optional fold down surface to widen the table for use; this feature also can be used as a modesty panel in school applications

(24) 6) table top rotates 90 degrees on the vertical axis to create a nesting feature. In this scenario, a write board surface is exposed and the table can be used as a mobile white board.

(25) Although the preferred embodiment of the present disclosure has been illustrated, and that form has been described in detail, it will be readily understood by those skilled in the art that various modifications may be made therein without departing from the spirit of the disclosure or from the scope of the appended claims.
