DETAILED DESCRIPTION
[0086] The present invention is generally directed towards chairs. The principles of the present invention, however, are not limited to chairs. It will be understood that, in light of the present disclosure, the chairs disclosed herein may have a variety of shapes, sizes, configurations, and arrangements. It will also be understood that chairs may include any suitable number and combination of features, components, aspects, and the like. In addition, while the chairs shown in the accompanying figures are illustrated as having particular styles, it will be appreciated the chairs may have other suitable styles and/or configurations. Further, the chair disclosed herein may have other configurations and arrangements such as glider chairs, stacking chairs, and the like.
[0087] Additionally, to assist in the description of various example embodiments of the chairs, words such as top, bottom, front, rear, sides, right, and left are used to describe the accompanying figures which may be, but are not necessarily, drawn to scale. It will further be appreciated the chairs may be disposed in a variety of desired positions or orientations, and used in numerous locations, environments, and arrangements. A detailed description of example embodiments of the chairs now follows.
[0088]
[0089] The chair 10 may include other parts and components, such as one or more brackets 38, and the brackets may be used to connect the seat 12 to the chair 10. For instance, a bracket 38 may be connected to the right front leg 30 and a bracket 38 may be connected to the left front leg 32. The brackets 38 may be part of the frame 24, or the brackets may be attached to the frame. The brackets 38 may be pivotally connected to the legs 30, 32 by fasteners, pins, rivets, and the like. One of ordinary skill in the art, after reviewing this disclosure, will appreciate that the chair 10 may include other parts and components, such as armrests and the like.
[0090] The chair 10 may be sized and configured for use by a single person, but the chair could also be smaller, such as a kid's chair, or larger, such as a two-person chair. The chair 10 may have other suitable designs depending, for example, upon its intended appearance, aesthetics, and the like. It will be understood that the chair 10 could have a variety of suitable shapes, sizes, and configurations, depending, for example, upon the intended use of the chair.
[0091] At least a portion of the chair 10 may be constructed from plastic, such as blow-molded plastic. For example, the seat 12 and/or backrest 18 may be constructed from blow-molded plastic. Advantageously, the blow-molded plastic seat 12 and backrest 18 may allow a strong, durable, and/or lightweight chair 10 to be quickly and efficiently manufactured. The seat 12 and backrest 18 could also be formed by other methods or processes such as injection molding, extrusion molding, vacuum forming, tumble molding, rotary molding, and the like. The seat 12 and backrest 18 may also be manufactured from different processes. For example, the seat 12 could be constructed from blow-molded plastic and the backrest 18 could be formed from vacuum or injection molded plastic. One of ordinary skill in the art, after reviewing this disclosure, will appreciate that any suitable portions of the chair 10 can be constructed from plastic. One of ordinary skill in the art, after reviewing this disclosure, will also appreciate that the chair 10, including the seat 12 and the backrest 18, may be constructed from other suitable materials such as wood, fabric, leather, nylon, acrylic, and the like.
[0092] One or more portions of the chair 10, such as the frame 24, the legs 30, 32, 34, and 36, and/or the brackets 38, may be constructed from strong and durable materials, such as metal. In an example embodiment, the frame 24, the legs 30, 32, 34, and 36, and the brackets 38 may be constructed from steel. If the frame 24, the legs 30, 32, 34, and 36, and the brackets 38 are constructed from steel, the chair 10 may be strong, sturdy, and able to support a significant amount of weight.
[0093] In an example embodiment, the legs 30, 32, 34, and 36 may be constructed from hollow metal tubes, and the metal tubing may be bent or formed into the desired shapes and configurations. For example, the legs 30, 32, 34, and 36 may have a generally oblong configuration with generally flat or planar sections and rounded sections. The legs 30, 32, 34, and 36 could have other suitable sizes, shapes, configurations, and/or arrangements, such as circular, square, rectangular, oval, and the like. The legs 30, 32, 34, and 36 may also be constructed from other materials with appropriate characteristics. After reviewing this disclosure, one of ordinary skill in the art will appreciate that the frame 24, legs 30, 32, 34, and 36, and brackets 38 may be constructed from other materials and have other suitable sizes, shapes configurations, and arrangements depending, for example, upon the intended use of the chair 10.
[0094] As shown in
[0095] The upper crossmember 44 may have a generally tubular configuration, and the upper crossmember may be constructed from metal tubing with a relatively larger diameter, such as between ? inches and ? inch. In an example embodiment, the upper portion of the rear legs 34, 36 may include rounded or curved portions, such as cutouts or recesses, and the upper crossmember 44 may be at least partially disposed in the recesses. The upper crossmember 44 may be securely connected to the legs 34, 36, such as by welding, fusing, bonding, and the like. The upper crossmember 44 may have an arched or curved configuration, and the arched configuration of the crossmember 44 may at least partially correspond to a curved portion of the lower surface 16 of the seat 12. For example, a portion of the lower surface 16 of the seat 12 may curve downwardly, and an arched portion of the upper crossmember 44 may curve downwardly. The downwardly curved portion of the upper crossmember 44 and the downwardly curved lower surface 16 of the seat 12 may generally match or be similar. Thus, a nominal distance between the upper crossmember 44 and the lower surface 16 of the seat 12 may be generally constant. The nominal distance between the upper crossmember 44 and the lower surface 16 of the seat 12 may reduce or eliminate pinch points and, because the nominal distance may be small, such as ? inch or less, the upper crossmember may support a portion of the seat.
[0096] The upper portion of the rear legs 34, 36 and the upper crossmember 44 may be movable relative to the seat 12. For example, the upper portion of the rear legs 34, 36 and the upper crossmember 44 may be slidable relative to the lower portion 16 of the seat 12. In an example embodiment, the upper portion of the rear legs 34, 36 and the upper crossmember 44 may be slidable relative to the lower portion 16 of the seat 12 while the chair 10 is folded and unfolded. The movement of the upper portion of the rear legs 34, 36 and/or the upper crossmember 44 may be controlled, which may allow the chair 10 to be easily folded and unfolded.
[0097] In an example embodiment, such as shown in
[0098] The guide member 46 may be movable or slidable within a guide 52, and the guide may be formed by at least a portion of the bracket 38 and/or a portion of the seat 12, such as a downwardly extending portion of the lower surface 16 of the seat. In an example embodiment, when the chair 10 is folded and unfolded, the guide members 46 and the guide 52 may at least partially control movement of the upper crossmember 44 and/or the rear legs 34, 36.
[0099] In an example embodiment, the bracket 38 may have a generally U-shaped configuration with walls 54, 56, and a connecting portion 58. For example, as shown in
[0100] The bracket 38 may include one or more attachment portions 62 and the attachment portions may be sized and configured to facilitate attachment of the bracket and the seat 12. In an example embodiment, such as shown in
[0101] The bracket 38 may include multiple support portions, such as support surfaces, which may be sized and configured to support the seat 12. In an example embodiment, the inner sidewall 56 of the bracket 38 may include a first portion 64, which may be disposed towards or proximate a front portion of the bracket, and a second portion 66, which may be disposed towards or proximate a rear portion of the bracket. An upper portion 68 of the front portion 64 of the bracket 38 may be sized and configured to support a portion of the seat 12, and an upper portion 70 of the rear portion 66 of the bracket may be sized and configured to support a portion of the seat. For example, the upper portion 68 of the front portion 64 of the bracket 38 may include an inwardly extending portion, which may have a generally planar upper surface, and the inwardly extending portion may be sized and configured to support the seat 12. The upper portion 70 of the rear portion 66 of the bracket 38 may include an inwardly extending portion, which may have a generally planar upper surface, and the inwardly extending portion may be sized and configured to support the seat 12.
[0102] The lower portion 58 of the bracket 38 may include an inner surface 72 and the inner surface may be sized and configured to support a portion of the seat 12, such as a lower portion of the downwardly extending lip or sidewall. The outer sidewall 54 of the bracket 38 may be sized and configured to contact, engage, abut., interlock, and/or be attached to a portion of the seat 12, such as an outer portion of the seat. For instance, the outer sidewall 54 of the bracket 38 may include an upper portion 74 and the upper portion may be sized and configured to contact, abut, connect, engage, interlock, and/or be disposed in a portion of the seat 12, such as a recess portion and/or attachment portion. Thus, in an example embodiment, the upper portion 74 of the outer sidewall 54 of the bracket 38 may be at least partially disposed in recessed portion of the seat 10, which may also be referred to as an attachment portion.
[0103] The upper portion 74 of the outer sidewall 54 of the bracket 38 may be disposed in a recess in an outer wall or sidewall of the seat 12. The upper portion 74 of the outer sidewall 54 of the bracket 38 may include an attachment portion 76, such as inwardly extending portion, which may be curved inwardly and downwardly. The attachment portion 76, such as shown in
[0104] The bracket 38 may include an opening or a cutout 78, which may be disposed in the inner sidewall 56 of the bracket. The opening 78 may extend longitudinally along a length of the bracket 38, and the opening may extend downwardly relative to an upper portion of the bracket. An upper portion of the opening 78 may be open or exposed, and the lower portion of the opening may be spaced apart from the lower surface 16 of the seat 12 by a gap 80. The opening 78 may include a front potion 82 disposed towards a front portion of the bracket 38 and the opening may include a rear portion 84 disposed towards a rear portion of the bracket.
[0105] The opening 78 may form at least a portion of the guide 52. For example, the guide 52 may include a lower portion 86 and the lower portion may have a generally planar or smooth upper surface. The lower portion 86 of the guide 52 may include an inwardly extending portion. A gap or space may be disposed between a front portion of the inwardly extending portion 86 and the front portion 82 of the opening 78. A gap or space may also be disposed between a rear portion of the inwardly extending portion 86 and the rear portion 84 of the opening 78. A downwardly extending notch 88 may be disposed between the rear portion of the inwardly extending portion 86 and the rear portion 84 of the opening 78. The guide 52 may be sized and configured to receive at least a portion of the guide member 46, and the guide may facilitate folding and unfolding of the chair 10.
[0106] In an example embodiment, the seat 12 and the bracket 38 may be attached by a friction, interference, and/or snap fit configuration. The bracket 38 may allow the seat 12 to be inserted downwardly into an upper portion of the bracket, and one or more portions of the bracket and/or seat may be sized and configured to bend or deform when the seat is attached to the bracket. Once the seat 12 is attached to the bracket 38, then the portions of the bracket and/or seat may revert or resiliently return, at least partially, to an initial configuration, which may facilitate connection of the seat and the bracket.
[0107] As shown in the accompanying figures, the inner sidewall 56 of the bracket 38 may include one or more attachment portions, such as the attachment portions 62. In an example embodiment, the inner sidewall 56 of the bracket 38 may include two inwardly extending attachment portions 62. The attachment portions 62 may extend inwardly and may be angled downwardly towards the lower portion 58 of the bracket 38, which may facilitate insertion of the seat 10 downwardly relative to the upper portion of the bracket. Thus, in an example embodiment, the bracket 38 may include multiple attachment portions, such as attachment portions 62, the attachment portions may extend inwardly and downwardly.
[0108] The brackets 38 may include one or more support surfaces and the support surfaces may be sized and configured to support the seat 12. For example, the upper portion 68 of the front portion 64 of the bracket 38, the upper portion 70 of the rear portion 66 of the bracket, the inner surface 72 of the lower portion 58 of the bracket, and/or the upper portion 74 of the outer sidewall 54 of the bracket may include one or more surfaces or portions that are sized and configured to support the seat 12. Advantageously, the multiple support surfaces may allow the seat 12 to be firmly supported.
[0109] As shown in the accompanying figures, the brackets 38 may include one or more angled portions, such as the upper portion 68 of the front portion 64 of the bracket 38, the upper portion 70 of the rear portion 66 of the bracket, the upper portion 74 of the outer sidewall 54 of the bracket, and/or the lower portion 86 of the guide 52. The angled portions 68, 70, 74, and/or 86, which may be referred to as flanges, may increase the stiffness and rigidity of the bracket. The flanges may facilitate attachment of the bracket 38 and seat 12 because, for example, the flanges may be disposed in receiving portions and/or the flanges may be sized and configured to contact, engage, abut., interlock, and/or be attached a particular portion of the seat 12. Because the flanges may be disposed on opposing sides of the bracket 38, the bracket may have considerable strength and rigidity.
[0110] The chair 10 may include one or more stops, and the stops may be used to control movement of the legs 30, 32, 34, 36 and/or the upper crossmember 44 relative to the seat 12. For example, the stops may abut, contact, or engage the crossmember 44 and/or the guide members 46 when the chair 10 is in a particular configuration. For instance, the upper crossmember 44 and/or the guide members 46 may abut, contact, or engage one or more of the stops when the chair 10 is in the unfolded or use position. The upper crossmember 44 and/or the guide members 46 may abut, contact, or engage one or more of the stops when the chair is in the folded or collapsed positions. In an example embodiment, the front portion 82 of the opening 78 may form a stop, such as when the chair 10 is in the use or unfolded position. In an example embodiment, the front lower crossmember 40 may form a stop, such as when the chair 10 is in the folded or collapsed position.
[0111] As shown in
[0112] As shown in the accompanying figures, the sidewalls 100 of the seat 12 may abut, contact, or engage the brackets 38. In an example embodiment, the seat 12 may be inserted into an upper portion of the brackets 38. For example, as shown in
[0113] As shown in
