FOLDING TABLE AND CHAIR

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

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation-in-part (CIP) of U.S. patent application Ser. No. 11/878,310, entitled FOLDING TABLE AND CHAIR, filed Jul. 23, 2007, which claims priority under 35 U.S.C. §119(e) to provisional U.S. Patent Application No. 60/832,136, filed on Jul. 21, 2006, the disclosures of which are expressly incorporated by reference herein in their entirety.

BACKGROUND OF THE INVENTION

1. Field of the Invention

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.

2. Related Art

Many folding tables that include a handle, or other carrying means, for transportation include a separate structure that is visible when the table is unfolded.

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 leafs. 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 leafs 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.

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.

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

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.

DETAILED DESCRIPTION OF THE INVENTION

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.

FIG. 1 shows a folding table 100 constructed in accordance with the principles of the invention. The table may include two leafs 122, 123 that make up a table top 120. Each table leg 110 may be pivotably connected to one of the leafs 122,123 that can be unlocked to fold via a push button release 105. FIG. 1A is a side view of the unfolded table 100 that shows two leafs 122, 123 joined together by a hinge 124.

FIG. 1B 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 110 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.

FIG. 1C illustrates table 100 in a folded position. In a folded position, the leafs 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.

FIG. 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 leafs 122, 123 opposite the hinge 124. FIG. 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 leafs 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 leafs 122, 123 in the folded position to facilitate carrying of the table 100.

FIG. 3 shows a latching mechanism 300 that may engage push button 105 to releasingly lock leg 110 in relation to table top 120. The latching mechanism 300 may be coupled to table top 120 using support plate 303. The leg 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 FIG. 1B. The latch may also include a clasp 311 that holds an upper planar surface of the hinge plate 305 to a lower planar surface of the support plate to “lock” the leg 110 in an unfolded position that is generally perpendicular to the table top 120.

Pressing the lever 309 downwardly releases the hinge plate 305 so that it may be rotated about pin 315 to allow the leg 110 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 303 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 311 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 110. This kind of arrangement is advantageous for the easy concealment of the mechanism used to lock/unlock the legs of a folding table.

FIG. 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 411 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.

Each of the front legs 409 may include a slot and keyhole arrangement for locking the chair 400 in an unfolded position. FIG. 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. FIG. 4B illustrates chair 400 in a folded position.

FIG. 5 shows a modem 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. FIG. 6 shows a dining set including table 500 with chairs 400.

FIG. 7 shows a slat style dining table 600 constructed in accordance with the principles of the invention. The table leafs 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.

FIG. 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 leafs 672, 673.

FIG. 9 illustrates a transitional folding chair 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 cross-support 716 at the rear end. The front cross-support 717 is pivotably connected to the front legs 709.

FIGS. 9A, 9B, and 9C illustrates the various steps of folding the chair 700. FIG. 9 and 9A show the chair 700 in an unfolded position suitable for use. FIG. 9B shows that the seat 705 may be rotated off of pegs 720, which permits the support 715 and front legs 709 to pivot upwardly to fold the chair 700. The chair in a folded position, is illustrated by FIG. 9C. FIG. 10 shows the dining set including table 650 with chairs 700.

FIG. 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 leafs 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.

FIG. 12 illustrates a folding chair 800 using yet another folding mechanism. As can be seen in FIG. 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. FIG. 13 shows a dining set including table 750 with chairs 800.

FIG. 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, FIG. 14 shows a mission style table 850 constructed in accordance with the principles of the invention. The leafs 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.

FIG. 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, FIG. 15 shows a mission chair 900 that may preferably include the alternative folding mechanism shown in FIG. 9, but other folding mechanisms that are consistent with the principles of the invention may also be used.

FIG. 16 shows a dining set incorporating the table of FIG. 14 with chairs constructed in accordance with the principles of the chair illustrated in FIG. 15. In particular, FIG. 16 shows a dining set including table 850 with chairs 900.

FIG. 17 illustrates a front view of an example of a folding chair 1000 according to yet another aspect of the invention. FIG. 17A illustrates a side view of the folding chair 1000 of FIG. 17. As seen in FIGS. 17 and 17A, the chair 1000 may include a plurality of front legs 1110, a seat back 1040, a lower support assembly 1300, a seat 1340, and a clip 1400. The seat back 1040 may include, for example, but is not limited to, a plurality of panels 1050. The lower support assembly 1300 may be connected between the plurality of front legs 1110 and the seat back 1040 to provide enhanced rigidity to the chair 1000 in a plane substantially parallel to, e.g., a surface (not shown) on which the chair 1000 may be placed.

FIG. 17B illustrates a side view of the chair 1000 in a partially folded configuration. As seen in FIG. 17B, the chair 1000 may be folded by applying, for example, an upward force F to the seat front 1120, causing the seat 1340 to pivotally move in a direction A toward the seat back 1040. The chair 1000 may be unfolded by applying, for example, a downward force (not shown) to the seat front 1120, causing the seat 1340 to pivotally move in a direction opposite to the direction A, away from the seat back 1040. The clip 1400 may be configured to engage a portion of the lower support assembly 1300 when the chair 1000 is configured in a substantially fully folded configuration (not shown), thereby locking the chair 1000 in the substantially fully folded configuration.

FIG. 17C illustrates an exploded view of the chair 1000. As seen in the illustration, the chair 1000 may further include a seat frame assembly 1180 and a pair of seat sides 1150. The seat 1340 and seat sides 1150 may be affixed to the frame assembly 1180 using, for example, a plurality of fasteners 1350. The fasteners 1350 may include, for example, but are not limited to, any one or more of a screw, a bolt, a pin, a lock-pin, a nail, a rivet, an adhesive, a weld, a clip, or the like. The frame assembly 1180 may be affixed to the front legs 1110 by way of fasteners 1170. The fasteners 1170 may include, for example, but are not limited to, any one or more of a screw, a bolt, a pin, a lock-pin, a nail, a rivet, an adhesive, a weld, or the like. The frame assembly 1180 may also be affixed to the seat back 1040 by way of, for example, a pair of lock-pins 1060 that are provided in a pair of recesses 1065 in the seat back 1040.

The rear assembly portion 1184 may be coupled to the front assembly portion 1182 by a pair of pivoting members 1125 (such as, e.g., a pin, a lock-pin, a rod, a bolt, or the like). In lieu of (or in addition to) the pair of pivoting members 1125, a single rod, or the like, may be provided between the opposing side members 1552. A stop (not shown) may be provided on the elongated members 1514 and/or the side members 1552 to prevent the front and rear assembly portions 1182, 1184 from rotating beyond a predetermined angle (such as, e.g., 0°—i.e., where the elongated members 1514 are in-line with the side portions 1552, as shown in FIG. 17D, or another angle between 0° and 90°).

FIG. 17E illustrates the plurality of legs 1110 connected to the seat sides 1150 of the chair 1000 of FIG. 17 in a substantially fully unfolded configuration of the chair 1000. The front-leg cross-member 1115 may be positioned between the legs 1110. Further, the front-leg cross-member 1115 may be affixed to the legs 1110. Each of the front legs 1110 may include a recess (not shown) in its upper portion for receiving the connecting extensions 1550 and/or the fasteners 1170.

FIG. 17F shows a more detailed illustration of the exemplary lower support assembly 1300 of the chair 1000 of FIG. 17. The lower support assembly 1300 may include a pair of cross-bars 1340, a cross-brace 1370, and a pair of knuckles 1380. Each of the cross-bars 1340 may include a recess 1342 at each end to receive, for example, a fastener 1070. Further, each cross-bar 1340 may be configured to rotate about its longitudinal axis. The cross-brace 1370 may be coupled to the cross-bars 1340 by means of the knuckle 1380. The knuckles 1380 may each be configured to rotate about the longitudinal axes of the cross-bars 1340, so that the cross-brace 1370 may rotate with respect to the cross-bar 1340 (such as, e.g., in the direction A shown in FIG. 17B).

Alternatively, the knuckles 1380 may be configured to fixedly engage each of the cross-bars 1340, preventing the cross-bars 1340 from rotational movement with respect to the knuckles 1380 or the cross-brace 1370, so that the entire lower support assembly 1300 would rotate as a single unit in the direction A shown in FIG. 17B.

The cross-bars 1340, the cross-brace 1370 and the knuckles 1380 may be made from a material, such as, for example, steel, aluminum, carbon-graphite, plastic, fiberglass, or the like, or any combination thereof.

FIG. 17G illustrates a perspective view of an example of the clip 1400 that may be used with the folding chair 1000 of FIG. 17. FIG. 17H shows a side view of the exemplary clip 1400. The clip 1400 may include a top-most sloped (first) portion 1410, a second portion 1420, a third portion 1430 and a fourth portion 1440. The fourth portion 1440 may be coupled to, for example, the lower portion 1525 of the seat frame assembly 1180. The clip 1400 may be configured such that the first portion 1410, second portion 1420 and third portion 1430 flex in a direction C when a force is applied to the top-most portion 1410 by the cross-brace 1370, thereby allowing a part of the cross-brace 1370 (shown in FIG. 17F) to slide past the first portion and under the second portion 1420. Thus, that part of the cross-brace 1370 may become lockably engaged by the second portion 1420 between the second portion 1420 and fourth portion 1440, and adjacent the third portion 1430.

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.
