Abstract

A folding table and chair each have an unobtrusive folding mechanism that cannot be easily seen when unfolded for use. Because the folding mechanism is not readily seen, folding tables and chairs of a number of well-known and popular styles can be provided that are suitable for use as everyday home furniture. Folding furniture may be particularly desirable for apartment and condominium dwellers who have limited living space and need to occasionally store bulky furniture to fully use such space. The folding furniture of the invention is also easier to move than traditional furniture, including the hinge of the table, which can also serve as a carrying handle.

Description

FOLDING TABLE AND CHAIR

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to U S Patent Application No 12/348,691, filed on January 5, 2009, the disclosure of which is expressly incorporated by reference herein in its entirety

BACKGROUND OF THE INVENTION [0002] 1 Field of the Invention

[0003] The invention is directed to a folding table and chair In particular, the table can be easily folded to make it more compact and transported for storage or relocation, and the chair can be folded flat to facilitate storage [0004] 2 Related Art

[0005] Many folding tables that include a handle, or other carrying means, for transportation flat include a separate structure that is visible when the table is unfolded [0006] An example of such a table is a typical "suitcase" style folding table The suitcase table includes a handle mounted to an outer edge of a table leaf A hinge, or other folding mechanism, is disposed at the center of the table and connects the opposing leaves The suitcase table's legs have a sliding leg-lock arrangement that is widely used in folding tables The legs can be folded within the thickness of the skirt surrounding the edge of each leaf The table can be folded in half such that the skirt of each leaf contacts one another to form an outer planar surface that forms the "suitcase" with the legs folded inside The skirt may include a latching mechanism so that the leaves can be secured together The secured, folded table can be transported by means of the separate handle that is not located on the same side of the outer planar surface of the suitcase as the hinge [0007] Many of the mechanisms that permit the suitcase table to fold and be transported are visible when the table is in use. Accordingly, these visible mechanisms are unsightly and make the typical folding table undesirable for everyday home use.

[0008] In smaller domiciles, furniture that is easily moved and storable is desired so that occupants can take full advantage of limited living space, which especially important in urban environments.

[0009] Accordingly, there is a need for a foldable table and chair that hides the folding and carrying mechanisms so that the table is sufficiently stylish and decorative for everyday use.

SUMMARY OF THE INVENTION

[0010] The invention meets the foregoing need and by providing a folding mechanism and carrying mechanism, respectively, that is not readily visible when unfolded, which results in a table and chair having appearances more similar to non-folding tables and chairs that are decorative and suitable for everyday use, as well as other advantages apparent from the discussion herein.

[0011] The invention describes a table with a table top and one or more legs connected to the table top with a pivot joint. The table includes a locking mechanism located within a recess in the table top and able to lock the pivoting legs in a position substantially perpendicular to the table top. The table also includes a release mechanism located in the recess that has an upper surface substantially planar with the upper surface of the table top. The release mechanism engages the locking mechanism and releases the pivoting leg so that it can be folded to a position substantially parallel to the table top. [0012] The locking mechanism may consist of a lever located at the end of a clasp. The release mechanism may consist of a push button. The table may have three legs. The table may have four legs. [0013] Additional features, advantages, and embodiments of the invention may be set forth or apparent from consideration of the following detailed description, drawings, and claims. Moreover, it is to be understood that both the foregoing summary of the invention and the following detailed description are exemplary and intended to provide further explanation without limiting the scope of the invention as claimed.

DETAILED DESCRIPTION OF THE INVENTION

[0045] The embodiments of the invention and the various features and advantageous details thereof are explained more fully with reference to the non-limiting embodiments and examples that are described and/or illustrated in the accompanying drawings and detailed in the following description It should be noted that the features illustrated in the drawings are not necessarily drawn to scale, and features of one embodiment may be employed with other embodiments as the skilled artisan would recognize, even if not explicitly stated herein Descriptions of well-known components and processing techniques may be omitted so as to not unnecessarily obscure the embodiments of the invention The examples used herein are intended merely to facilitate an understanding of ways in which the invention may be practiced and to further enable those of skill in the art to practice the embodiments of the invention. Accordingly, the examples and embodiments herein should not be construed as limiting the scope of the invention, which is defined solely by the appended claims and applicable law. Moreover, it is noted that like reference numerals represent similar parts throughout the several views of the drawings.

[0046] Figure 1 shows a folding table 100 constructed in accordance with the principles of the invention. The table may include two leaves 122, 123 that make up a table top 120. Each table leg 1 10 may be pivotably connected to one of the leaves 122, 123 that can be unlocked to fold via a push button release 105. Figure 1A is a side view of the unfolded table 100 that shows two leaves 122, 123 joined together by a hinge 124. [0047] Figure 1 B is an enlarged view of the push button release 105. The button 105 may be disposed in a recess 125 of the table top 120. Here, the button 105 is pushed down to unlock the leg 1 10 so that it may fold, but the button may be any suitable mechanism for disengaging a lock or latch that holds the leg 110 in place when the table 100 is unfolded for use.

[0048] Figure 1C illustrates table 100 in a folded position. In a folded position, the leaves 122, 123 are spaced apart, primarily by the thickness of the legs 110. This space may expose the hinge 124 so that it can be used as a handle for carrying the table 100 in the folded position for transportation or storage.

[0049] Figure 2 is a side view of table 100 that illustrates that it may rest flat on the ground or other surface in a folded position, supported by an edge of the leaves 122, 123 opposite the hinge 124. Figure 2A is a close-up view of the hinge 124. The hinge 124 may include a handle 201 that is held in place by collars 203, which are coupled to the leaves 122, 123 by flanges 205. The handle can be fixedly coupled to the collars of one leaf while being pivotably connected to the collars of the other leaf. Alternatively, the handle can be pivotably connected to all of the collars and held in place by end caps 207 disposed on the outer collars to prevent longitudinal movement of the handle. Preferably, most of the handle 201 is disposed above the edges of the leaves 122, 123 in the folded position to facilitate carrying of the table 100

[0050] Figure 3A shows a latching mechanism 300 that may engage push button 105 to releasably lock leg 1 10 in relation to table top 120 The latching mechanism 300 may be coupled to table top 120 using support plate 303 The leg 110 may be coupled to the latching mechanism 300 using hinge plate 305 that is rotatably connected the support plate 303 at pin 315 A latch 301 , which may be biased towards the push button release 105 by a mechanism such as a spring (not shown), can be provided to fix the hinge plate 305 in relation to both the support plate 303 and table top 120 The latch 301 may include a lever 309 that is adapted to engage push button release 105 within recess 125 of Figure 1 B The latch may also include a clasp 31 1 that holds an upper planar surface of the hinge plate 305 to a lower planar surface of the support plate to "lock" the leg 1 10 in an unfolded position that is generally perpendicular to the table top 120

[0051] Pressing the lever 309 downwardly releases the hinge plate 305 so that it may be rotated about pin 315 to allow the leg 1 10 to rotate into a folded position that is generally parallel to the table top 120 To unfold the leg 110, it can be rotated so that an edge of hinge plate 305 will push the clasp 311 against biasing force provided by the latch 301 so that leg 110 can fully rotate When the upper planar surface of hinge plate 305 abuts the lower planar surface of the support plate 303, the clasp 31 1 will spring back due to the biasing force of latch 301 to lock the leg 110 in place The clasp 311 may have a tapered surface 313 adapted to engage a leading edge of hinge plate 305 to facilitate unfolding of the leg 1 10 This kind of arrangement is advantageous for the easy concealment of the mechanism used to lock/unlock the legs of a folding table

[0052] Figure 4 shows a folding chair 400 constructed in accordance with the principles of the invention The chair 400 includes a back 403 and a seat 405 having a cushion 406 The back may be supported by rear legs 407 that extend from the surface the chair 400 is resting on to the top of back 403 The seat 405 can be pivotably coupled to rear legs 407 The front of seat 405 may be supported by front legs 409 that are substantially shorter in length than rear legs 407. Extra lateral support may be provided by support 415 that is connected to front legs 409 on a front end and pivotably connected to a cross-support 416 at a back end. The support 415 primarily provides lateral support in a front-to-back direction, and the cross-support 416 primarily provides lateral support in a side-to-side direction. Here, seat 405, legs 407, 409, support 415, and cross-support 416 include a frame 41 1 preferably made of lightweight cast aluminum. But other materials that are known to be suitable for constructing folding chairs can be used in accordance with the principles of the invention. [0053] Each of the front legs 409 may include a slot and keyhole arrangement for locking the chair 400 in an unfolded position. Figure 4A shows the front leg 409 having a slot 422 and a keyhole 423 within the leg that both engage a tab 417 of support 415. When the tab 417 is seated in the slot 422, the support 415 is locked relative to the cross-support 416 and the front leg 409, thereby preventing the seat 405 from pivoting and "locks" the chair 400 in the unfolded position. Moving the tab 417 to the keyhole 423 "unlocks" the chair 400 and allows the tab to move in a manner that permits the support 415 to rotate relative to the front leg 409, which, in turn, permits a pivotal motion of the seat 405 to allow folding of the chair 400. Figure 4B illustrates chair 400 in a folded position.

[0054] Figure 5 shows a modern style dining table 500 constructed in accordance with the principles of the invention. Each leaf 522, 523 may comprises two wooden slabs 526, 528, 530, 532 that conceal the seam where the table 500 is folded. The table 500 also may include the previously described push button release 105 for locking/unlocking legs 510. Here, the push button release 105 is shown as an aluminum button to accent the wooden slabs 526, 528, 530, 532. A skilled artisan would recognize that a variety of materials can be used with the table of the invention, including the material for the push button release, depending on the aesthetic look desired. Figure 6 shows a dining set including table 500 with chairs 400. [0055] Figure 7 shows a slat style dining table 600 constructed in accordance with the principles of the invention. The table leaves 622, 623 can be made up of slats 630. The push button release 105 can be made of a wood or other material, contrasting to the slats 630 for adding a stylish appeal.

[0056] Figure 8 shows a transitional table 650 constructed in accordance with the principles of the invention. The table 650 may include tapered legs 660 and a beaded skirt 665 for an elegant look. The push button release can be covered by a veneer 656 to match the table top 670 made up of leaves 672, 673.

[0057] Figure 9 illustrates a transitional folding char 700 using an alternative folding mechanism. The chair 700 includes a back 703, a seat 705 having a cushion 706, rear legs 707, front legs 709, support 715, and cross-support 716. Here, the chair 700 also includes a front cross-support 717 that provides side to side lateral support in a similar manner to the cross-support 716. The support 715 may be joined to the front cross-support 717 at the front end, and pivotably connected to the σoss-support 716 at the rear end. The front cross- support 717 is pivotably connected to the front legs 709.

[0058] Figures 9A, 9B, and 9C illustrate the various steps of folding the chair 700. Figure 9 and 9A show the chair 700 in an unfolded position suitable for use. Figure 9B shows that the seat 705 may be rotated off of pegs 720, which perrrits the support 715 and front legs 709 to pivot upwardly to fold the chair 700. The chair in a folded position is illustrated by Figure 9C. Figure 10 shows the dining set including table 650 with chairs 700. [0059] Figure 11 shows a traditional style table 750 constructed in accordance with the principles of the invention. The table 750 may include engraved details 776 in the leaves 772, 773. The legs 760 can have the appearance of classic lathe turned legs that end in boxed shoulders 775 integrated into the skirt 765. The push button release, which may covered by a veneer 756 to match the table, operates to lock/unlock the legs 760. [0060] Figure 12 illustrates a traditional folding chair 800 using yet another folding mechanism. As can be seen in Figure 12A, the front legs 809 may be folded by pressing a push button release 815 disposed within a recess 825 of the seat 805 that functions similar to the previously described release for a folding table Pressing the push button release 805 unlatches the front legs 809 so that the seat 805 may be rotated and the chair 800 will lay substantially flat for storage Figure 13 shows a dining set including table 750 with chairs 800

[0061] Figure 14 shows a perspective view of yet another exemplary folding table constructed according to the principles of the invention having a mission style In particular, Figure 14 shows a mission style table 850 constructed in accordance with the principles of the invention The leaves 872, 873 may include ceramic or stone tiles 876 for creating the mission look The legs 860 may be straight and sturdy to provide a hand made look consistent with the mission style The push button release 105 may be made to match either the tiles or wood of table

[0062] Figure 15 shows a perspective view of yet another exemplary folding chair constructed according to the principles of the invention in an unfolded position In particular, Figure 15 shows a mission chair 900 that may preferably include the alternative folding mechanism shown in Figure 9, but other folding mechanisms that are consistent with the principles of the invention may also be used

[0063] Figure 16 shows a dining set incorporating the table of Figure 14 with chairs constructed in accordance with the principles of the chair illustrated in Figure 15 In particular, Figure 16 shows a dining set including table 850 with chairs 900 [0064] According to an alternative aspect of the invention, a table 100 may be provided that has a solid, one-piece table top 120 as shown in Figure 17 Such a table 100 may not have leaves 122, 123 or a hinge 124 It may, however, have one or more folding legs 100 and a push release button 105 The button 105 may be pushed down to unlock the leg 100 so that it may fold, or the button 105 may be any other suitable mechanism for disengaging a lock or latch that holds leg 110 in position when the table 100 is unfolded The button 105 may function as described above with respect to Figure 1 B, although other configuration and mechanisms, as understood by one skilled in the relevant arts, are contemplated and with the scope of the invention. Figure 18 displays the top of the table 100, and Figure 19 shows the side of the table.

[0065] Figure 20 illustrates the underside of the table 100 when the legs 100 are folded.

The legs 110 are folded at an angle relative to the sides of the table 100, although any configuration of the legs in a folded position is contemplated and within the scope of the invention.

[0066] The invention provides unobtrusive folding mechanisms for both a table and chair that provides a folding table and chair, both of which may be constructed in a number of styles, that are sufficiently decorative for regular, everyday home use.
