1. Field of the Invention
The present invention generally relates to furniture and, in particular, to tables.
2. Description of Related Art
Some conventional tables include table tops constructed from relatively heavy materials, such as metal or wood. These relatively heavy table tops may undesirably increase the overall weight of the tables making them more difficult to move and more expensive to ship. In addition, metal and wood table tops may be susceptible to rust and/or other damage.
Some conventional tables include a plastic table top and a metal frame connected to the table top to help strengthen and reinforce the table top. Unfortunately, the table top can be damaged as the frame is connected.
A need therefore exists for a table that eliminates or diminishes the disadvantages and problems described above.
One aspect is a table that may include a table top and one or more legs. The legs may be movable between an extended or use position and a collapsed or storage position. The table top may be constructed from plastic and is preferably constructed using a compression molding process. The table top, however, may be constructed from other materials and/or other molding or manufacturing processes, if desired. The table top may include a pair of table top sections and the table may be folded in half for more efficient storage and/or shipping.
Another aspect is a table that may include a table top formed using a compression molding process, and the compression molded table top may be constructed from plastic and/or other suitable materials. The compression molded table top preferably includes a first table top section and a second table top section, which may be interchangeable. For example, the first and second table top sections may be molded using the same mold or substantially similar molds, which may allow the first and second table top sections to be identical or substantially identical in size, shape and/or configuration.
Still another aspect is a table that may include a molded table top with one or more ribs. The molded table top preferably includes a pattern of ribs and the pattern of ribs may include portions that are different than other portions. For example, the table may include a frame connected to the table top and the pattern of ribs may be denser or spaced closer together proximate a central portion of the table top. The ribs may also be spaced closer together the farther the ribs are spaced from the frame. Advantageously, this may allow the ribs and/or frame to be sized and configured to provide a table top with generally consistent strength and/or rigidity. In addition, the ribs may have different shapes, sizes, configurations and arrangements depending, for example, upon the positioning or the ribs, whether the table includes a frame and the intended use of the table. For instance, the ribs may be thicker or more closely spaced to provide additional strength and/or rigidity, or the ribs may be thinner or spaced a larger distance apart to provide decreased strength and/or rigidity. Because the ribs may have different shapes, sizes, configurations and arrangements, the amount of plastic required to make the table top may be reduced. In particular, if a portion of the ribs are spaced apart a greater distance, then that may reduce the amount of plastic required to mold the table top.
A further aspect is a table that may include a molded plastic table top and a layer may be attached to the table top. The layer, which may also be an insert or cover, may be attached to an upper surface and/or sides of the table top. The layer may hide cosmetic defects, provide a visually attractive appearance, be used for decorative purposes, and the like.
A still further aspect is a table that may include a molded plastic table top and a frame that is preferably sized and configured to help strengthen and/or reinforce the table top. For example, the frame may include support members, such as rails, which may be sized and configured to help increase torsional rigidity of the table top. The support members are preferably constructed from metal and preferably have a generally tubular configuration. In addition, the table top and frame preferably allow the table to be foldable. For instance, the table top and frame may fold in half to facilitate shipping and/or storage of the table. The table top and the frame, however, need not be foldable. Moreover, the frame need not be constructed from tubular support members or metal, and the frame may have other configurations and components that are constructed from other materials depending, for example, upon the intended use of the table.
Still another further aspect is a table that may include a table top and a frame with a plurality of support and cross members. For example, the frame may include two support members that extend along the length of the table top and two cross members that are connected to the support members. The table may include legs that are connected to the cross members and the legs may be moveable between an extended or use position and a collapsed or storage position relative to the table top. In particular, the support members may include openings and the cross members may be inserted into the openings to allow the legs to pivot relative to the table top. The openings preferably have a non-circular configuration and the portions of the cross members inserted into the openings preferably also have non-circular cross-sectional configurations. For instance, the openings and the cross member may have oval, elliptical, oblong or egg-shaped configurations. With these non-circular configurations, the cross members may be relatively loosely held within the openings when the legs are in the collapsed or storage position, but held tightly within the openings when the legs are in the extended or use position.
Another aspect is a table that may include a table top with one or more bosses that are sized and configured to receive at least a portion of one or more fasteners, such as screws, bolts, rivets and the like. The bosses may allow various components to be connected to the table. For example, all or a portion of a frame may be connected to the table top by fasteners and the bosses. In greater detail, the bosses preferably extend outwardly from a portion of the table top, such as a lower portion of the table top. Advantageously, the bosses may be integrally formed as part of a one-piece construction during the manufacturing process. For example, the bosses may be integrally formed with the table top as part of a unitary, one-piece construction during a molding process, such as a compression molding process.
Still another aspect is a table that may include a table top, a frame and bosses that may be used to position and/or attach the frame to the table top. For example, the bosses may contact, abut and/or engage a portion of the frame to position the frame in the desired location and/or the bosses may attach the frame to the table top. The table top may also include one or more ribs and the ribs may be sized and configured to strengthen, reinforce and/or increase the rigidity of the table top. The ribs may also be used to help position and/or attach the frame to the table top. For instance, a portion of the frame may contact, abut and/or engage the ribs to help position the frame in the desired location and/or to help attach the frame to the table top. By contacting, abutting and/or engaging the bosses, ribs or other portions of the table top, such as a downwardly extending lip, the frame may be quickly and easily positioned a desired location and/or attached to the table top.
Yet another aspect is a table that may include a table top, frame, fastener bosses and ribs. The bosses may be spaced apart from the ribs, if desired. This may allow, for example, the frame to be spaced apart from the ribs, which may help reduce stresses applied to the ribs.
A further aspect is a structure that may include a fastener boss with a body and reinforcing members, such as ribs, that are sized and configured to reinforce and/or strengthen the body. For example, the reinforcing members may extend away from the body. In particular, the reinforcing members may extend away from the body in a generally tangential direction. By disposing the reinforcing members in a generally tangential configuration, stresses applied to the reinforcing members (such as those associated with a fastener and/or connecting an item to the boss) may be primarily tensile and compressive forces, in contrast to torsional. This may advantageously allow the reinforcing members to better bear such stresses. In addition, the bodies and reinforcing members of the bosses may have a variety of different shapes and configurations depending, for example, upon the size and/or intended use of the structure. For instance, the body may have a generally cylindrical configuration, but the body may also have a configuration that is generally square, hexagon, polygonal and the like.
A still further aspect a structure that may include at a fastener boss with a body and reinforcing members that extend away from the body. For instance, the reinforcing members may extend in a direction that is offset from the center of the fastener boss. For example, the reinforcing members may be offset from the center of the boss by about 90 degrees, about 60 degrees, about 45 degrees, about 30 degrees or less. In addition, the reinforcing members may be disposed within a range relative to the center of the boss. For example, the reinforcing members may be disposed an angle between about 80 degrees and about 100 degrees, between about 85 degrees and about 95 degrees, between about 50 degrees and about 70 degrees, between about 55 degrees and about 65 degrees, between about 35 degrees and about 55 degrees, between about 40 degrees and about 50 degrees, between about 20 degrees and about 40 degrees and/or between about 25 degrees and about 35 degrees. The reinforcing members may also be disposed at larger and/or smaller angles, and the reinforcing members may extend in other suitable directions. In will be appreciated, however, that the reinforcing members do not have to be offset from the center of the boss and the reinforcing members may be disposed in other angles and configurations relative to the boss.
Yet another further aspect a structure that may include a fastener boss with reinforcing members that extend away from the body at an oblique angle. The reinforcing members may also be slanted, sloped or disposed in other suitable angles and configurations depending, for example, upon the intended use of the structure. In addition, the same structure may include multiple types and configurations of bosses. For instance, if the structure is a table, then the table may include bosses with reinforcing members disposed at different angles and/or configurations.
Another aspect is a structure that may be constructed from molded plastic and include a boss with a body and reinforcing members that are integrally formed as part of a unitary, one-piece structure. For example, the structure and bosses may be integrally formed during a molding process, such as compression molding, injection molding, blow molding, rotational molding and the like. All or a portion of the structure may also be constructed from other materials, such as plastic, metal or wood, using other suitable processes.
Advantageously, these structures may be used to form various items such as table tops, barriers, walls, panels, enclosures, floors, roofs, chairs, basketball systems and the like. It will be appreciated that these structures may form all or just a portion of an item, such as a component or piece of the structure.
Still another aspect is a fastener boss with a receiving portion that is sized and configured to allow items to be connected to the boss. The boss may be integrally formed with a molded plastic structure and the boss may include reinforcing members. The reinforcing members may extend outwardly in a radial or non-radial direction. The reinforcing members may also have other suitable shapes, sizes, configurations and arrangements depending, for example, upon the intended use of the molded plastic structure.
These and other aspects, features and advantages of the present invention will become more fully apparent from the following detailed description of preferred embodiments and appended claims.
The appended drawings contain figures of preferred embodiments to further illustrate and clarify the above and other aspects, advantages and features of the present invention. It will be appreciated that these drawings depict only preferred embodiments of the invention and are not intended to limit its scope. The invention will be described and explained with additional specificity and detail through the use of the accompanying drawings in which:
The present invention is generally directed towards a table. The principles of the present invention, however, are not limited to tables. It will be understood that, in light of the present disclosure, the table disclosed herein can be successfully used in connection with other types of furniture and/or structures.
Additionally, to assist in the description of the table, words such as top, bottom, front, rear, right and left may be used to describe the accompanying figures, which are not necessarily drawn to scale. It will be appreciated, however, that the table can be located in a variety of desired positions and/or orientations. A detailed description of the table now follows.
As shown in
As shown in
In some embodiments, the openings in the rails 24, 26 and the cross members 28, 30 may have non-circular cross-sectional configurations. With these non-circular configurations, the cross members 28, 30 may be relatively loosely held within the openings when the legs 14, 16, 18, 20 are positioned in the collapsed or storage position, but held tightly within the openings when the legs are in the extended or use position, for example, as disclosed in U.S. Pat. No. 7,100,518, which is incorporated by reference in its entirety. It will be appreciated, however, that the openings and the cross members 28, 30 do not require non-circular cross-sectional configurations and that the openings and the cross members may have any suitable configurations, including circular cross-sectional configurations if desired. It will also be appreciated that the table 10 does not require the frame 22 and that the legs 14, 16, 18, 20 may be connected to the table top 12 using any other suitable structures and components.
The table top 12 may be formed from plastic using, for example, a compression molding process. As shown in
The table top sections 36, 38 may allow the table 10 to be folded in half, which may provide a compact configuration that facilitates efficient shipping and/or storage of the table. In particular, as shown in
As shown in
As shown in
In further detail, as shown in
The body 58 of the boss 52 may include a receiving portion 60 that is sized and configured to receive and/or retain at least a portion of a fastener 56. For example, the fastener 56 may include a threaded portion that is sized and configured to bite into or otherwise engage at least a part of the receiving portion 60 to receive and retain at least a portion of the fastener within the receiving portion. For instance, the fastener 56 may be a screw that may be screwed into the receiving portion 60 and the threaded portion of the screw may bite into and engage a surface 62 to help connect the fastener to the boss. It will be appreciated, however, that the fasteners 56 may be connected to the bosses 52 in any desired configurations or arrangements depending, for example, upon the intended use of the table 10.
As shown in
The reinforcing members 64, 66 are preferably connected to the body 58 to help the boss 52 withstand such stresses. For example, the reinforcing members 64, 66 may be integrally formed with the body 58 as part of a unitary, one-piece structure. In particular, the fastener bosses 52 may be formed from molded plastic and the body 58 and the reinforcing members 64, 66 may be integrally formed as part of a unitary, one-piece structure during the molding process. Advantageously, this may allow the bosses 52 to be integrally formed as part of a unitary, one-piece table top 12 or table top section 36, 38 during a molding process, such as compression molding, injection molding, blow-molding process and the like. The bosses 52, however, do not have to be integrally formed and the bosses do not have to be integrally formed with the table top 12 or the table top sections 36, 38. In addition, the bosses 52 need not be formed from plastic and may be constructed from other suitable materials and with various manufacturing processes.
Advantageously, the bosses 52 may have a variety of suitable shapes, sizes, configurations and arrangements depending, for example, upon the intended use of the table 10. For example, the reinforcing members 64, 66 may extend away from the body 58 of the boss 52, which increase the strength of the boss. In particular, the outwardly extending reinforcing members 64, 66 may extend in a non-radial direction away from the body 58. For example, as shown in
The reinforcing members 64, 66 may also extend away from the body 58 of the bosses 52 in a direction that is offset from the center of the boss. For example, the reinforcing members 64, 66 may be generally aligned with an outer edge or perimeter of the boss. The reinforcing members 64, 66 may also be offset from the body 58 of the boss 52 by an angle, such as about 90 degrees, about 60 degrees, about 45 degrees, about 30 degrees or less. The reinforcing members 64, 66 may also be disposed within a range, such as between about 80 degrees and about 100 degrees, between about 85 degrees and about 95 degrees, between about 50 degrees and about 70 degrees, between about 55-degrees and about 65 degrees, between about 35 degrees and about 55 degrees, between about 40 degrees and about 50 degrees, between about 20 degrees and about 40 degrees and/or between about 25 degrees and about 35 degrees. If desired, the reinforcing members 64, 66 may be disposed in at other angles and/or offset from the center of the fastener boss 52 at greater or lesser angles. In addition, the reinforcing members 64, 66 may extend outwardly at an oblique or other suitable angle.
As shown in
As mentioned above, the fastener bosses 52, the body 58 and the reinforcing members 64, 66 may be integrally formed as part of a unitary, one-piece structure during a molding process. Advantageously, the bosses 52 can be used in connection with a wide variety of structures and components, such as tables 10, table sections, sheds (including roof panels, wall panels, floor panels, door panels, gables, shelves or skylights), basketball systems (including backboards or bases), fences, barriers, panels, chairs (including chair seats, backrests or armrests), toys and the like. The fastener bosses 52, bodies 58 and/or reinforcing members 64, 66, however, need not be integrally formed as part of a unitary, one-piece structure and may be constructed from other suitable materials using various manufacturing processes. Significantly, this may allow the fastener bosses 52, the body 58 and/or the reinforcing members 64, 66 to be used in even more structures and/or contexts.
The table top 12 may include one or more ribs, which may be sized and configured to strengthen and/or reinforce the table top 12. In particular, as shown in
As shown in
The pattern of ribs 68 may be sized and configured to help provide different strength and/or reinforcement for different portions of the table top section 36, 38. In particular, the pattern of ribs 68 may be sized and configured to provide more strength and/or reinforcement in places spaced apart from the frame 22 than in places proximate the frame. For example, as shown in
The table top section 36, 38 preferably includes pattern of ribs including a first set of one or more ribs 68 that may extend along all or at least a substantial portion of the table top section's length and a second set of one or more ribs that may extend along all or at least a substantial portion of the table top section's width. For instance, as shown in
As shown in
As shown in
As shown in
The raised portions 76 may also facilitate storage of a plurality of table top sections 36, 38 for later assembly as part of a table 10. For instance, the table top sections may be stacked on top of each other with the raised portions 76 generally aligned. Desirably, this may help reinforce and/or strengthen the stack, which may include two, three, four or more table top sections, if desired. Any number or combination of adjacent table top sections may face the same direction or opposing directions in the stack, if desired.
As shown in
In some instances, by contacting, abutting and/or engaging the fastener bosses 52, the frame 22 may be secured to the table top 12 in a position that is spaced apart from the ribs 68, which may help reduce stresses applied to the ribs. It will be appreciated, however, that the frame 22 need not be spaced apart from the ribs and that the frame may be positioned in other suitable locations. It will also be appreciated that the table top does not require any ribs 68 or fastener bosses 52.
As shown in
Advantageously, the retainer 78 may retain the table 10 in the folded position so that the table does not unintentionally unfold when the folded table is being carried, transported and/or stored. In addition, the retainer 78 may be sized and configured to automatically engage the other portion of the table to simplify the engagement process. The retainer 78 may also be quickly and easily connected to the cross members 28, 30, which may simplify the manufacturing process and allow the retainer to be used in a wide variety of situations and environments. Additionally, the retainer 78 may be connected to suitable portions of the table top 12 to secure the retainer in a fixed position. Significantly, because the retainer 78 may be connected to the table top 12 and/or the cross members 28, 30 by a snap, friction or interference fit, the retainer may be easy to use and mechanical fasteners may not be required. It will be appreciated, however, that the retainer 78 may be connected to the table 10 by mechanical fasteners, adhesives, and the like and that the retainer can be attached to any suitable portions of the table.
Desirably, one portion of the retainer 78 is securely connected to a first portion of the table 10, such as the cross member 28, so that the retainer is permanently connected or not easily removed from the first portion. Another portion of the retainer 78 is preferably selectively connected to the second portion of the table top 12, such as the cross member 30, so that the retainer may be quickly and easily attached and detached. This may allow the retainer 78 to quickly and easily secure the table 10 and table top 12 in the folded position, and allow the table and table top to be quickly and easily moved into the unfolded position. It will be appreciated that either or both portions of the retainer 78 may be selectively or permanently connected to suitable portions of the table 10 and/or the table top 12 depending, for example, upon the design and/or intended use of the table.
As shown in
In further detail, the clip 82 may include one or more resiliently deformable arms that project from the body 80. The arms preferably include free ends that are separated by an opening or gap. As the cross member 28 is inserted into the gap, the free ends of the arms may deflect outwardly to allow the cross member to be inserted into the clip 82. The arms may then resiliently return to their original configuration to receive and retain the cross member 28 within the clip 82. It will be appreciated that the cross member 28 may be connected to the clip 82 using other suitable types of connections.
When the table top 12 is moved into the folded position, the cross member 30 is preferably received and retained in the clip 84 by a snap fit, a friction fit, an interference fit or the like. For example, the clip 84 may include resiliently deformable arms that project from the body 80. The arms preferably include free ends that are separated by an opening or gap. As the cross member 30 is inserted into the gap, the free ends of the arms may deflect outwardly to allow the cross member to be inserted into the clip 84. The arms may then resiliently return to their original configuration to receive and retain the cross member 30 within the clip 84. It will be appreciated that the cross member 30 may be connected to the clip 84 using other suitable types of connections.
As mentioned above, the arms of the clip 82 preferably include free ends that are separated by a gap or opening that are sized and configured to receive and retain the cross member 28. The arms of the clip 84 also preferably include free ends that are separated by a gap or opening that are sized and configured to receive and retain the connection rod 30. Preferably, the cross member 28 is more securely attached to the retainer 78 than the cross member 30 so that when the table top 12 is moved to the unfolded position, the cross member 30 is released from the clip 84. It will be appreciated, however, that the cross members 30, 28 may be selectively and/or securely attached to the clips 82, 84, as desired.
As best seen in
As shown in
As shown in
As mentioned above, the table top 12 and/or a table top section 36, 38 may be formed from molded plastic. In some embodiments, an insert or cover may be placed into a mold, a charge of moldable plastic may be placed onto the insert or cover, and then the insert and the moldable plastic may be molded into the table top and/or table top section using, for example, a compression molding process or other molding process. Significantly, the insert may help hide cosmetic defects and/or may provide a visually attractive appearance. The insert is preferably positioned in the mold such that it may form part of an upper working surface of the molded table top and/or table top section and may be sized and configured to form all or at least a substantial portion of the upper working surface. The insert preferably comprises a graphical insert that may include a sheet with one or more graphics printed thereon. The sheet may have a porous configuration which may help prevent the sheet from forming air bubbles. One such exemplary sheet may be a TeslinĀ® sheet (commercially available from PPG Industries, One PPG Place, Pittsburgh, Pa. 15272, United States of America), but other sheets and/or other inserts may be used. It will be appreciated that the insert may have other sizes and may be positioned in other locations to form other portions of the molded table top and/or table top section. It will also be appreciated that the table top 12 and the table top sections 36, 38 do not require any graphical inserts or any other inserts.
If desired, one or more graphics may be screen printed onto the upper working surface and/or other surfaces of the table top 12 and the table top sections 36, 38. This may also help hide cosmetic defects and/or may provide a visually attractive appearance. It will be appreciated, however, that this printing is not required.
Significantly, one or more of components of the table 10 may be constructed from a relative strong material, such as metal. For example, the legs 14, 16, 18, 20; the frame 22; the rails 24, 26; the cross members 28, 30, 32, 34; and/or the rail sections 40, 42, 44, 46 may be constructed from metal tubes, which may advantageously be strong, yet relatively lightweight. It will be appreciated, however, that these components do not require tubular configurations and may have other shapes and/or configurations. It will also be appreciated that these components need not be constructed from metal and may be constructed from other suitable materials, if desired.
As discussed above, components of the table 10 may be constructed from plastic. Exemplary molding systems and methods that may be used to constructed these plastic components are disclosed in U.S. patent application Ser. No. 11/771,378, which was filed Jun. 29, 2007, entitled MOLDING SYSTEMS AND METHODS; U.S. provisional patent application Ser.
