DETAILED DESCRIPTION
[0035] An illustrative embodiment of a chair 10 in accordance with the present disclosure is shown in FIGS. 1 and 2. The chair 10 includes a seat 12, a base 14, and a connector 16 configured to secure the seat 12 to the base 14. The connector 16 includes a channel 20 defined by the seat 12 and configured to receive a cross-member 34 of the base 14, a retention cover 22 configured to extend into the channel 20 to engage with the cross-member 34, and a plurality of fasteners 24 configured to couple the retention cover 22 with the seat 12 to hold the cross-member 34 in the channel 20 as shown in FIGS. 2-11A.
[0036] The seat 12 includes a seat pan 11, extending from a front of the chair 10 toward a rear of the chair 10, and a backrest 13, extending upward from a rear end of the seat pan 11, to support a user sitting on the chair 10 as shown in FIG. 1. In the illustrative embodiment, the seat 12 includes a user-support portion 18 and a seat-support portion 19 coupled to the user-support portion 18 that together form the seat pan 11 and backrest 13. In some embodiments, the seat 12 is formed from plastic material and shaped through a blow molding process. In some embodiments, the fasteners 24 engage with the seat-support portion 19 to hold the retention cover 22 relative to the seat 12. In some embodiments, threaded inserts 26 engage with pockets 28 in the seat 12, and the fasteners 24 engage with the threaded inserts 26 to hold the retention cover 22 relative to the seat 12. The threaded inserts 26 may provide a significantly increased length of contact with the fasteners 24 compared to engaging the fasteners 24 with the seat 12 directly (which is generally limited to the thickness of the seat-support portion 19). In some embodiments, the length of contact between the fasteners 24 and the threaded inserts 26 is at least 200% of the thickness of the seat-support portion 19. In some embodiments, the seat-support portion 19 has a thickness of 0.1 inches, and the threaded inserts 26 provide a length of contact with the fasteners 24 of 0.5 inches. In some embodiments, the threaded inserts 26 are formed from metal or another material that is stronger than the material used to form the seat-support portion 19. In some embodiments, the threaded inserts 26 have external threads for securing the threaded inserts 26 into the pockets 28 and internal threads for engaging with threads of the fasteners 24. In some embodiments, the external threads of the threaded inserts 26 are larger than the threads of the fastener 24.
[0037] The user-support portion 18 and seat-support portion 19 are connected along a perimeter of the seat 12 and spaced apart across a remainder of the seat 12 to define an internal cavity 62 therebetween as shown in FIGS. 9-11A. In some embodiments, a tack-off 60 (sometimes called a pillar) extends from the channel 20 defined by the seat-support portion 19 toward the user-support portion 18 to engage with the user-support portion 18 and provide a reinforcement between the user-support portion 18 and seat-support portion 19 as shown in FIGS. 8, 8A, 10, and 10A. In some embodiments, ventilation holes 64 extend through the seat pan 11 and/or backrest 13 into the cavity 62 to provide air flow into and out of the cavity 62.
[0038] The base 14 is configured to support the seat 12 relative to a surface S beneath the chair 10 as shown in FIG. 1. In the illustrative embodiment, the base 14 includes a pair of spaced apart legs 32 and a cross-member 34 extending between the legs 32 as shown in FIGS. 2 and 3. The legs 32 define feet 36 that extend frontward from lower ends of the legs 32 (see FIG. 2). The cross-member 34 extends rearward from upper ends of the legs 32 (see FIG. 3). The legs 32 are arranged at an angle and cantilevered to the feet 36 to position the seat 12 relative to the surface S that the feet 36 are resting on.
[0039] In the illustrative embodiment, the channel 20, retention cover 22, and cross-member 34 are arranged in complementary V-shapes as shown in FIG. 3. The cross-member 34 of the base 14 includes a first beam 37 and a second beam 38 arranged at an angle relative to the first beam 37 to define a V-shape of the cross-member 34. The retention cover includes a body 40 and a plurality of holes 42 extending through the body 40 to receive the plurality of fasteners 24 of the connector 16. The body 40 defines a first arm 44 and a second arm 46 arranged at an angle relative to the first arm 44 to define a V-shape of the retention cover 22. The channel 20 includes a first section 52 and a second section 54 arranged at an angle relative to the first section 52 to define a V-shape of the channel 20. The apexes of the V-shaped channel 20, retention cover 22, and cross-member 34 points toward the rear of the chair 10. The first beam 37 of the cross-member 34 and the first arm 44 of the retention cover 22 are arranged to extend along the first section 52 of the channel 20, and the second beam 38 of the cross-member 34 and the second arm 46 of the retention cover 22 are arranged to extend along the second section 54 of the channel 20.
[0040] The body 40 of the retention cover 22 defines a face 41 extending along a first side of the body 40 and a groove 47 extending along an opposite second side of the body 40 as shown in FIGS. 4 and 5. The groove 47 is configured to engage with the cross-member 34 of the base 14 (see FIGS. 9A, 10A, and 11A). The retention cover 22 also defines a front wall 43 and an opposite rear wall 45. The front and rear walls 43, 45 extend between the face 41 and the groove 47. The front and rear walls 43, 45 are angled with respect to one another such that a distance between the front and rear walls 43, 45 decreases as the front and rear walls 43, 45 extend toward the groove 47. In some embodiments, the retention cover 22 is formed from a rigid material, such as metal or plastic. In some embodiments, the retention cover 22 is solid in cross-section. In some embodiments, the retention cover 22 is hollow in cross-section. In some embodiments, the retention cover 22 is formed using an injection molding or blow molding process. In some embodiments, the retention cover 22 is a single, unitary, and integral structure sized to extend along substantially an entire length of the channel 20.
[0041] The channel 20 is defined by a front surface 61 and a spaced apart rear surface 63 connected by a curved intermediate surface 65 as shown in FIGS. 8-11A. The front and rear surfaces 61, 63 are arranged at a draft angle with respect to one another such that the channel 20 is tapered with a distance between the front and rear surfaces 61, 63 decreasing as the front and rear surfaces 61, 63 extend toward the intermediate surface 65. The draft angle of the channel 20 allows for efficient manufacturing and assembly of the chair 10, and maximizes engagement between the channel 20 and cross-member 34. In the illustrative embodiment, the front wall 43 of the retention cover 22 is arranged substantially parallel to the front surface 61 of the channel 20, and the rear wall 45 of the retention cover 22 is arranged substantially parallel to the rear surface 63 of the channel 20. In some embodiments, the front and rear surfaces 61, 63 are contiguous along channel 20 as shown in FIG. 8. In some embodiments, the face 41, front and rear walls 43, 45, and groove 47 are contiguous along the body 40 of the retention cover 22 as shown in FIGS. 4 and 5. In some embodiments, the front surface 61 is arranged at an angle relative to the surface S beneath the chair 10 in a range from about 50 degrees to about 70 degrees as shown in FIG. 10. In some embodiments, the rear surface 63 is arranged at an angle relative to the surface S beneath the chair 10 in a range from about 35 degrees to about 55 degrees. At least a portion of the front surface 61 of the channel 20 is arranged between the cross-member 34 of the base 14 and the surface S beneath the chair 10 along a line perpendicular to the surface S as shown in FIGS. 9-11A. At least a portion of the groove 47 and front wall 43 of the retention cover 22 is also arranged between the front surface 61 and the cross-member 34 along a line perpendicular to the surface S. The front and rear walls 43, 45 of the retention cover 22 cooperate with the front and rear surfaces 61, 63 of the channel 20, respectively, to minimize forces on the fasteners 24. For example, as forces are applied to the user-support portion 18, the front wall 43 of the retention cover 22 can engage with the front surface 61 of the channel 20 to distribute at least a portion of the forces away from the fasteners 24.
[0042] In the illustrative embodiment, the seat-support portion 19 of the seat 12 defines a front brace 15 and a pair of rear braces 17 extending away from the user-support portion 18 as shown in FIGS. 3 and 6-11A. The rear braces 17 are arranged along respective ones of the first and second sections 52, 54 of the channel 20 opposite of the channel 20 from the front brace 15. In some embodiments, the front brace 15 defines at least a portion of the front surface 61 of the channel 20, and the rear braces 17 define at least a portion of the rear surface 63 of the channel 20. In some embodiments, the front and rear braces 15, 17 are arranged substantially parallel to the surface S beneath the chair 10 and substantially co-planar to one another. In some embodiments, the face 41 of the retention cover 22 is substantially co-planar with the front and rear braces 15, 17 when arranged in the channel 20.
[0043] In an exemplary process for assembling the chair 10, the threaded inserts 26 are secured in the pockets 28 defined in the seat-support portion 19 as shown in FIGS. 3, 9, and 9A. The cross-member 34 of the of the base 14 extends into the channel 20 (compare FIG. 8 with FIG. 7) and is arranged in contact with the intermediate surface 65 as shown in FIGS. 9-11A. The retention cover 22 extends into the channel 20 (compare FIG. 7 with FIG. 6) and is arranged with the groove 47 in contact with cross-member 34 of the base 14. The fasteners 24 extend through the holes 42 in the retention cover 22 to engage with the threaded inserts 26 to couple the retention cover 22 with the seat 12 and hold the cross-member 34 in the channel 20 as shown in FIGS. 3, 9, and 9A. In the illustrative embodiment, the fasteners 24 are rearward of the cross-member 34. While four fasteners 24 and four inserts 26 are shown, more or less fasteners 24 and/or inserts 26 may be used.
[0044] In the illustrative embodiment, the channel 20 and the cross-member 34 of the base 14 are arranged at an angle relative to the surface S beneath the chair 10 such that the channel 20 and the cross-member 34 are positioned closer to the surface S as the channel 20 and the cross-member 34 extend in a direction from the front of the chair 10 toward the rear of the chair 10 as shown in FIG. 10. The angle biases the seat 12 rearward relative to the base 14 when a user sits on the chair 10 to bias the cross-member 34 into the channel 20 toward the front of the chair 10 in order to minimize forces tending to bias the cross-member 34 away from the channel 20. In some embodiments, the angle is in a range from about 5 degrees to about 15 degrees. In some embodiments, a distance between the face 41 of the retention cover 22 and the groove 47 increases as the retention cover 22 extends in a direction from the rear of the chair 10 toward the front of the chair 10 as shown in FIGS. 3-5.
[0045] As shown in FIGS. 8, 8A, 10, and 10A, the exemplary tack-off 60 extends from the channel 20 into the seat 12 toward the user-support portion 18 to engage with the user-support portion 18 and provide a reinforcement between the user-support portion 18 and seat-support portion 19. In the illustrative embodiment, the tack-off 60 is positioned between the first and second sections 52, 54 of the channel 20 at the apex of the V-shape and arranged to transmit forces on the user-support portion 18 from a user sitting on the chair 10 to the cross-member 34 of the base 14. Arranging the tack-off 60 along a centerline of the chair 10 assists in distributing forces more evenly across the chair 10 and minimize bending forces on the user-support portion 18. In some embodiments, the tack-off 60 is arranged in another location, such as forward or rearward of the channel 20. In some embodiments, multiple tack-offs 60 may be distributed along the channel 20. In some embodiments, the tack-off 60 is arranged in a substantially frustopyrimidal shape that includes front and rear portions substantially parallel to the front and rear surfaces 61, 63 of the channel 20 (see FIG. 10). The tack-off 60 may assume different shapes in some embodiments, such as frustoconical, cylindrical, square, or triangular, among other geometric and non-geometric shapes. In some embodiments, the tack-off 60 can be larger or smaller (e.g., extending a greater or lesser distance along the first and second sections 52, 54 of the channel 20). The tack-off 60 is arranged at an angle relative to the surface S beneath the chair 10 based at least in part on the angles , of the front and rear surfaces 61, 63, respectively, such that the tack-off 60 extends further away from the surface S as the tack-off 60 extends in a direction from the rear of the chair 10 toward the front of the chair 10 in order to provide resistive forces from the cross-member 34 to the user-support portion 18 in a direction based at least in part on the angle of the channel 20 and cross-member 34 in order to balance relative forces between the base 14 and the seat 12 when a user sits in the chair 10. In some embodiments, an upper end of the tack-off 60 is secured to the user-support portion 18 (sometimes called an I-beam construction), such as by fusing a portion of the tack-off 60 with a portion of the user-support portion 18 during a blow molding process. In some embodiments, an upper end of the tack-off 60 is spaced apart from the user-support portion 18, but engages with the user-support portion 18 when a user sits in the chair 10.
[0046] As shown in FIGS. 11 and 11A (sectional views cutting across the chair 10 perpendicular to one of the beams 37, 38 of the cross-member 34), the groove 47 of the retention cover 22 contacts the cross-member 34 along a portion of a circumference of the cross-member 34 and one or more of the surfaces 61, 63, 65 of the channel 20 contact the cross-member 34 along other portions of the circumference of the cross-member 34 to collectively define a percentage of wrap W around the cross-member 34. The groove 47 of the retention cover 22 and surfaces 61, 63, 65 of the channel 20 contact the cross-member 34 along at least a portion of a length of the cross-member 34 between the legs 32 and, together with the percentage of wrap W, defines a contact area between the cross-member 34 and the connector 16. In the illustrative embodiment, the percentage of wrap W is not consistent across the length of the cross-member 34 due to gaps in the surfaces 61, 63, 65 of the channel 20, such as for the pockets 28 and tack-off 60. In some embodiments, the percentage of wrap W is consistent across a majority of the length of the cross-member 34. In some embodiments, the contact area includes a percentage of wrap W of 50% to 95% of the circumference of the cross-member 34 for 30% to 50% of the length of the cross-member 34. In some embodiments, the contact area includes a percentage of wrap W of 75% to 95% of the circumference of the cross-member 34 for 40% to 50% of the length of the cross-member 34.
