Aspects of the disclosure relate to functional mechanical designs and apparatus. Specifically, aspects of the disclosure relate to folding tables with improved utility.
Functional furniture plays an important role in everyday activities. Exemplary activities may relate to the workplace, the home, retail locations, office settings, educational locations, eateries, leisure, and any other imaginable activity that may utilize furniture such as a table.
Folding features may increase the utility of functional furniture such as a table. A folding table may be easily stowed away in a much smaller space than is occupied by the table when unfolded. Many conventional folding tables, however, are associated with substantially decreased strength relative to non-folding tables. Moreover, many conventional folding tables are associated with substantially decreased seating space relative to non-folding tables. The decreased seating space may at least partially result from tables legs and folding assemblies that infringe on the space where someone sitting at the table may want to position their knees and/or legs.
It would be desirable, therefore, to provide systems and methods for folding tables with increased seating space. It would be further desirable for the folding tables to be associated with increased structural strength.
Aspects of the disclosure relate to a folding table with increased seating space. The table may include a tabletop. The table may include a plurality of legs affixed to an underside of the tabletop. The legs may be configured to be movable, bi-directionally, between an unfolded position and a folded position.
The table may include two or more folding mechanisms. Each folding mechanism may include a central support bar affixed to the underside of the tabletop via a hinged bracket. Each folding mechanism may also include a transverse support bar assembly.
The transverse support bar assembly may include a central portion configured to slide along the central support bar. The transverse support bar assembly may also include a first side support bar that extends from the central portion to one of the legs, and a second side support bar that extends from the central portion to another one of the legs.
The objects and advantages of the disclosure will be apparent upon consideration of the following detailed description, taken in conjunction with the accompanying drawings, in which like reference characters refer to like parts throughout, and in which:
A folding table with increased seating space is provided. The table may include a tabletop. The tabletop may be rectangular. In some embodiments, the tabletop may be circular, oval, square, or any suitable tabletop shape. The tabletop may, in certain embodiments, be made partly or wholly out of wood, plastic, or other suitable material, or a suitable combination thereof.
The table may include a plurality of legs affixed to an underside of the tabletop. The legs may be configured to be movable, bi-directionally, between an unfolded position and a folded position.
In some embodiments of the table, the plurality of legs may be four legs. The legs may, in certain preferred embodiments, be straight. Straight legs may in certain embodiments, be completely or substantially straight. In some embodiments, straight legs may be legs that do not form a wishbone shape in pairs.
The tabletop may define four corners. Each corner may be adjacent to a perimeter of the tabletop. When the tabletop is rectangular, the four corners may, for example, be adjacent to the four corners of the rectangular perimeter. When the tabletop is circular, the four corners may be adjacent to the four corners of a rectangle that is inscribed by the circular perimeter. Being adjacent to the perimeter may, in one embodiment, include being within one inch from the perimeter. Other embodiments may feature corners that are within two, three, four, five, or any other suitable relatively small number of inches from the perimeter. Each one of the four legs may be situated at one of the four corners.
In certain embodiments, a first one of the legs may be connected to a second one of the legs via a first connecting bar. The first one of the legs may be situated at a first one of the corners. The second one of the legs may be situated at a second one of the corners. The first connecting bar may be situated against the underside of the tabletop and may extend from the first one of the legs at the first one of the corners to the second one of the legs at the second one of the corners.
In some embodiments, the first connecting bar may be secured against the underside of the tabletop via one or more braces. The braces may allow the first connecting bar to rotate in place. Rotation of the first connecting bar may allow the first and the second legs to move, in unison, between the folded and unfolded positions.
A third one of the legs may be connected to a fourth one of the legs via a second connecting bar. The third one of the legs may be situated at a third one of the corners. The fourth one of the legs may be situated at a fourth one of the corners. The second connecting bar may be situated against the underside of the tabletop and may extend from the third one of the legs at the third one of the corners to the fourth one of the legs at the fourth one of the corners.
In certain embodiments, the second connecting bar may be secured against the underside of the tabletop via one or more braces. The braces may allow the second connecting bar to rotate in place. Rotation of the second connecting bar may allow the third and the fourth legs to move, in unison, between the folded and unfolded positions.
In some embodiments, the first and the second connecting bars may form the only connections between the legs.
The table may include two or more folding mechanisms. The folding mechanisms may, in certain embodiments, be formed from steel, aluminum, or other suitable material or combination of materials. Each folding mechanism may include a central support bar affixed to the underside of the tabletop via a hinged bracket. The central support bar may be a hollow tube. The central support bar may be square.
Each folding mechanism may also include a transverse support bar assembly. The transverse support bar assembly may include a central portion configured to slide along the central support bar. The central portion may be a hollow shape (e.g., square) configured to fit around the central support bar.
The transverse support bar assembly may also include a first side support bar that extends from the central portion to one of the legs, and a second side support bar that extends from the central portion to another one of the legs.
In certain embodiments of the table, the first side support bar may be a straight bar that forms an acute angle at a point of attachment with the central portion. The second side support bar may also be a straight bar that forms an acute angle at a point of attachment with the central portion. The transverse support bar assembly thus may form a V-shape.
In certain embodiments, each of the first and second side support bars may attach to one of the legs. The attachment may, in some embodiments, be an offset attachment. The point of attachment may (offset or otherwise) be, in an exemplary embodiment, within four inches below the underside of the tabletop when the legs are in the unfolded position. In other embodiments, the point of attachment may be within two, three, five, six, or other number of inches or percentage of the leg, below the underside of the tabletop when the legs are in the unfolded position. The folding mechanisms may thereby be associated with a low profile. Low-profile folding mechanisms may increase the space for knees and legs of a person seated at the table. The table may thereby be more comfortable and useful to those using the table. The table may also thereby seat more people than conventional folding tables without low-profile folding mechanisms.
In some embodiments, the first and second side support bars may be tubes (hollow or otherwise). The tubes may, in certain preferred embodiments, be square. In other embodiments, the tubes may be circular. Tubular side support bars may provide increased structural strength over flat side support bars. Increased structural strength may contribute to enabling the low profile of the folding mechanism while maintain sufficient strength to support the table.
The table may, in certain embodiments, include a pin assembly. The pin assembly may be configured to lock the central portion of the transverse support bar assembly in place against the central support bar when the legs are in the unfolded position.
The table may, in some embodiments, include a skirt assembly. A skirt assembly may also be referred to as an apron assembly. The skirt assembly may substantially follow a perimeter of the tabletop. The skirt assembly may extend below the underside of the tabletop such that when the legs are in the folded position the skirt assembly extends beyond the legs. The skirt assembly may, in certain preferred embodiments, include enlarged corner portions. The enlarged corner portions may be made of plastic or another suitable material that may minimize scratching or other damage. The enlarged corner portions may extend further down than the rest of the skirt assembly. The skirt assembly may thereby minimize scratching of a top surface of another tabletop upon which (or under which, if upside down) the folding table is stacked.
Methods for producing a folding table with increased seating space are provided. A method may include affixing a plurality of legs to an underside of a tabletop, and configuring the legs to be movable, bi-directionally, between an unfolded position and a folded position via multiple folding mechanisms. Installing each of the folding mechanisms may include affixing a central support bar to the underside of the tabletop via a hinged bracket, and securing a central portion of a transverse support bar assembly against the central support bar such that the central portion is configured to slide along the central support bar. A method may also include attaching one end of a first side support bar to the central portion, and another end to one of the legs, and attaching one end a second side support bar to the central portion, and another end to another one of the legs.
Apparatus and methods described herein are illustrative. Apparatus and methods in accordance with this disclosure will now be described in connection with the figures, which form a part hereof. The figures show illustrative features of apparatus and method steps in accordance with the principles of this disclosure. It is understood that other embodiments may be utilized, and that structural, functional, and procedural modifications may be made without departing from the scope and spirit of the present disclosure.
Other illustrative dimensions may include (W×L): 18″×60″, 18″×72″, 18″×96″, 24″×48″, 24″×60″, 24″×72″, 24″×96″, 30″×60″, 30″×96″, 36″×60″, 36″×72″, 36″×96″.
Illustrative round table dimensions may include: 48″ Round, 60″ Round, and 72″ Round. Dimensions of a round table may be measured as the diameter across the tabletop.
Table 300 also includes a skirt assembly.
Table 500 includes the underside 501 of the tabletop. Central support bar 503 is shown affixed to underside 501 via hinged bracket 505. Central portion 507 is shown as configured to slide along central support bar 503. First side support bar 509 is shown extending from central portion 507 to leg 521. Second side support bar 511 is shown extending from central portion 507 to leg 519. Components 507-511 may be part of the transverse support bar assembly, which, together with components 503 and 505 may form part of one of the folding mechanisms of table 500.
Table 500 also includes connecting bar 513, which is shown connecting legs 519 and 521. Connecting bar 513 is shown secured by at least one brace 515 (table 500 is shown in a preferred configuration with three braces securing each connecting bar). Connecting bar 513 may be configured to rotate in place. Rotation of connecting bar 513 may result from, and allow, transition of legs 519 and 521 between folded and unfolded positions.
Table 500 shows that the point of connection 517 between the side support bars and the legs may be offset. The offset connection may allow for the folding mechanism to extend and retract when the legs transition between folded and unfolded positions.
Table 500 also shows that point of connection 517 may be close to the top end of the leg, i.e., close to underside 501 when the legs are unfolded. In some embodiments, point of connection 517 may be within two inches of underside 501 when the legs are unfolded. Point of connection 517 may be within one inch of the bottom of skirt assembly 525 when the legs are unfolded. In other embodiments, point of connection 517 may be within three, four, five, six, seven, eight, nine, ten, or any other suitable number of inches of underside 501 when the legs are unfolded. In other embodiments, the closeness may be measured as a percentage of the length of the leg. For example, point of connection 517 may be within 1/15th of leg away from underside 501 when the legs are unfolded. In other embodiments, point of connection 517 may be within 1/14th, 1/13th, 1/10th, 1/9th, ⅛th, 1/7th, ⅙th, ⅕th, ¼th, or other suitable percentage of the leg away from underside 501 when the legs are unfolded.
Table 500 also includes securing clasp 523. Securing clasp 523 may secure the legs in the folding position. Table 500 also shows corner portions 527 of skirt assembly 525.
The view in
Table 800 also includes a folding mechanism 803.
Tabs 1402 and 1404 may be connected to the ends of first side support bar 1406 and second side support bar 1408, and may in turn connect the side support bars to the table legs. The holes in the tabs for connecting to the table legs may be extended away from the ends of the side support bars, thereby facilitating an offset connection with the legs.
Leg assembly 1500 may be installed at one end of a folding table. Another substantially identical leg assembly may be installed at another end of the table.
Leg assembly 1511 may include cross bar 1517. Cross bar 1517 may, in certain embodiments, be secured against the underside of the folding table. Cross bar 1517 may, in some embodiments, be a round bar that is configured to rotate when the leg assembly is folding and unfolding. Leg assembly 1511 may also include base bar 1519. Base bar 1519 may be configured to rest horizontally on the ground. Base bar 1519 may have a flat bottom. Base bar 1519 may be a square bar or tube. One or more leg bars 1515 may connect cross bar 1517 and base bar 1519. Leg bars 1515 may be offset from the center of cross bar 1517 and base bar 1519 to provide the cantilevered nature of leg assembly 1511.
The cantilevered nature of leg assembly 1511 may facilitate increased legroom and utility for a user of the table. Other features, such as a low-profile folding mechanism (i.e., with connection points that are close to the underside of the table) and/or bump brackets (which may provide extra support for the legs and thereby compensate for any reduction in support due to a low-profile folding mechanism) may be provided in conjunction with leg assembly 1511 to further increase seating space and utility of the table.
A height (measured to the underside, or, alternatively, the top, of the tabletop) of some or all of the illustrative models shown in collection 1700 may be approximately 28″, 29″, 30″, 31″, 32″, or any other suitable folding table height. An exact height measurement may, in certain preferred embodiments, be substantially 29.15″.
Table 1800 shows an embodiment of one preferred implementation of portions of folding and support mechanisms for the table. For example, table 1800 includes bump bracket 1801. Bump bracket 1801 (shown in more detail as bracket 1900 in
The increased support provided by bump bracket 1801 may facilitate, at least in part, a low-profile folding mechanism that provides increased seating space. For example, certain aspects of a low-profile folding mechanisms may be associated with reduced support strength for the legs. This may be a result of an attachment point of the mechanism with the leg that is closer to the tabletop, and/or an absence of connections between the legs apart from a connecting bar at the underside of the tabletop. The bump bracket may provide additional support for the legs and thereby contribute to a folding table that is strong and stable while featuring a low-profile folding mechanism that provides increased seating space.
In some embodiments, the bump bracket may be part of a skirt assembly of the table. In other embodiments, the bump bracket may be separate from a skirt assembly of the table. The skirt assembly may, for example, not be as strong as a dedicated bump bracket with respect to supporting the legs. This may be, in part, because the skirt assembly is designed to be modular, interchangeable, and/or low profile. The skirt assembly may also not be in an optimal position for leg support. For example, the skirt assembly may include 45-degree corner assemblies. Because it may be desirable for the legs to be installed as close to the corners of the table as possible, the 45-degree corner assemblies of the skirt assembly may not be in the correct position to support the legs.
Upright portion 1901 may include protrusion 1903. Protrusion 1903 may protrude inward towards a center of the table (i.e., in direction 1909 along longitudinal axis 1907). Protrusion 1903 may engage the leg when the leg is unfolded. The view in
Engagement of leg 1923 by protrusion 1903 may apply pressure against the leg when unfolded. For example, while folding mechanism 1917 may provide force to leg 1923 in direction 1911 along longitudinal axis 1907 (i.e., pushing the leg outward to prevent the leg from folding inward), protrusion 1903 may engage the leg and apply force in the opposite direction, toward direction 1909 along longitudinal axis 1907, stabilizing the leg. Stabilizing the leg may, for example, reduce shaking and wobbling and/or reduce a risk of the leg overextending past an optimal unfolded position. The bump bracket may therefore facilitate, at least in part, a folding leg with low-profile folding mechanisms and/or a single cross bar connection while maintaining stability properties that may be similar to that of a welded leg.
Bump bracket 1900 may be designed to have a degree of elasticity or flexibility. The elasticity may allow the leg to extend slightly past a perpendicular unfolded position. Extending slightly past perpendicular may allow a locking mechanism (e.g., knob/plunger assembly 1927) of folding mechanism 1917 to be engaged and/or disengaged. The elasticity may result, at least in part, from materials used in bump bracket 1900. For example, steel may be used for some or all portions of bump bracket 1900. In particular, forming gusset plates 1913 from steel (in certain embodiments, 1018 steel) may contribute to the bump bracket providing sufficient force between protrusion 1903 and leg 1923 when leg 1923 is locked into the unfolded position, while allowing enough flex for leg 1923 to disengage from the locked state in order to return to the folded position. In some embodiments, a material of protrusion 1903 may also contribute to the elasticity. For example, protrusion 1903 may be a stamped boss formed of 1018 steel. In some embodiments, protrusion 1903 may be fully or partially formed of or coated with an elastomeric material (e.g., plastic, silicone, rubber, etc.).
Table 2000 is shown without aprons. In some embodiments, a bump bracket may be built into, or formed as part of, table aprons. In other embodiments, the aprons may not be capable or optimal for supporting the legs in the way the bump brackets do to provide support. This may be due to the material used for the apron, or the way the apron is constructed or attached to the table. This may also be due to a positioning of the apron. For example, as shown elsewhere in the instant disclosure, the aprons may, in some embodiments, be installed at the edge of the tabletop. This may necessitate a 45 degree corner piece. It may be desirable, in certain embodiments, to also install the legs as close to the corners as possible. When the aprons and legs are so positioned, the 45 degree corner piece may therefore preclude the leg from receiving extra support from the apron.
