  • Embodiments of the present invention relate generally to office furniture, and more particularly to swiveling, rotating tablet arms for nesting chairs.
  • the term "nesting chair” is used herein in its broadest sense to refer to a chair capable of interfacing with other similar chairs in a way such that each chair occupies less area space on average in a nested position than it does in an operable position.
  • Nesting chairs may be used in rooms such as conference rooms or meeting spaces where the meeting area may be rearranged from a seating configuration to an open space configuration.
  • Such nesting chairs may be horizontally stacked, aligned, and/or lined up in a front-to-back configuration, such as along a wall or corridor, to minimize space occupied by the nested chairs.
  • Nesting chairs may eliminate the need to lift and stack chairs, and may further facilitate setup, takedown, and storage of the chairs.
  • the term “coupled” is used in its broadest sense to refer to elements which are connected, attached, and/or engaged, either directly or integrally or indirectly via other elements, and either permanently, temporarily, or removably.
  • the term “swivelably coupled” is used in its broadest sense to refer to elements which are coupled in a way that permits one element to swivel with respect to another element.
  • the term “rotatably coupled” is used in its broadest sense to refer to elements which are coupled in a way that permits one element to rotate with respect to another element.
  • the term “slidably coupled” is used in its broadest sense to refer to elements which are coupled in a way that permits one element to slide or translate with respect to another element.
  • the terms “horizontal,” “horizontally,” and the like are used in their broadest sense to refer to a direction along or parallel to a plane relative to a nesting chair 102, where such plane is defined by the lines H1 and H2 depicted in FIGS. 2-4. Although lines H1 and H2 are not shown in all views, the plane defined by H1 and H2 in FIGS. 2-4 serves to define such plane in all views as such plane is defined relative to nesting chair 102.
  • the terms “vertical,” “vertically,” and the like are used in their broadest sense to refer to a direction along or parallel to a line relative to a nesting chair 102, where such line is defined by the line V1 of FIGS. 2-4. Although line V1 is not shown in all views, line V1 serves to define such line in all views as such line is defined relative to nesting chair 102.
  • FIGS. 1-4 depict a nesting chair 102 with a tablet arm 100 in an operable position, according to various embodiments of the present invention.
  • Chair 102 includes a support frame 120, as well as a seatback (back) 106 and a seat 108 coupled to support frame 120.
  • Support frame 120 includes front legs 114 and rear legs 116. Wheels 118 or casters or rollers may be coupled with the ends of front legs 114 and/or rear legs 116 to further facilitate movement and/or placement of chair 102 along a floor.
  • Tablet arm 100 includes support members 110 and 112, and a tablet 104 is coupled with support member 112 according to some embodiments.
  • Tablet arm 100 and chair 102 are depicted in an operable position in FIGS. 1-4.
  • operable position is used in its broadest sense to refer to a position in which seat 108 is oriented to permit a user to sit upon it (for example, in a substantially horizontal oricntation), and/or in which tablet 104 is in a substantially horizontal orientation and ready for use to support or permit writing or the resting of a hand or arm thereon.
  • support member 112 is swivelably coupled to support member 110 according to embodiments of the present invention.
  • Support member 110 also herein referred to as a mounting arm, is rigidly coupled with support frame 120; for example, support member 110 may be welded to support frame 120 by welding at weld sites 202, according to some embodiments.
  • Support member 110 may be a fixed support member such as a solid bar, a hollow bar, and/or a tube according to various embodiments of the present invention.
  • Support member 112 is swivelably coupled with support member 110 such that support member 112 swivels along a substantially horizontal plane.
  • Support member 112 may be a solid bar, a hollow bar, and/or a tube according to some embodiments of the present invention.
  • Support members 110 and/or 112 may be made with metal or metal alloy such as steel or aluminum, for example; alternatively, support members 110 and/or 112 may be made with plastic, wood, or other rigid or semi-rigid material according to embodiments of the present invention.
  • tablet 104 is also rotatably coupled to tablet arm 100 at support member 112, according to embodiments of the present invention.
  • tablet 104 is rotatably coupled to support member 112 by collars 302, according to embodiments of the present invention. This permits tablet 104 to rotate about axis 304. Such rotation may be, for example, between a substantially horizontal tablet 104 position and a non- substantially horizontal tablet 104 position.
  • a non-substantially horizontal tablet 104 position may be, for example, a vertical orientation, or an almost vertical orientation, or the orientation shown in FIG. 7, according to some embodiments of the present invention.
  • stop member 222 is a U-shaped bracket rigidly coupled with support member 112. Such coupling may be welding, for example.
  • tablet 104 rests upon stop member 222 in a substantially horizontal orientation. Tablet 104 may be rotated away from stop member 222 along axis 304 until the bottom of tablet 104 contacts tablet stop 1328, which serves to prevent tablet 104 from rotating too far away from stop member 222.
  • tablet stop 1328 stops rotation of tablet 104 away from stop member 222 at a position where tablet 104 is short of being in a vertical orientation.
  • tablet stop 1328 stops rotation of tablet 104 at a position where tablet 104 is in the angular position depicted in FIG. 7. Placement of tablet stop 1328 on support member 112 may be varied to achieve different predetermined rotation angles, as measured between tablet 104 in the operable position and tablet 104 after being rotated about axis 304.
  • a slidable coupling may also be included between tablet 104 and support member 112 according to some embodiments of the present invention.
  • Collars 302 in addition to rotatably coupling tablet 104 with support member 112, may also slidably couple tablet 104 with support member 112.
  • Such a slidable coupling permits tablet 104 to be translated horizontally along axis 304 of support member 112 while tablet arm 100 is in the operable position, for example. This translation or sliding permits a user of tablet arm 100 to position tablet 104 closer or further from the body to position tablet 104 to varying body sizes and types and to varying usage posture preferences.
  • Such sliding permits a wider array of positioning choices than a tablet arm which merely permits tablet rotation about a single vertical axis.
  • the combination of support member's 112 ability to swivel in a substantially horizontal plane and a slidable coupling between tablet 104 and support member 112 permits a much larger number of positional placements of tablet 104 along a horizontal plane, and permits a user to fine tune or customize with precision tablet 104 placement, according to various embodiments of the present invention.
  • FIGS. 5-8 depict the chair 102 and tablet arm 100 of FIGS. 104 in a nested position according to embodiments of the present invention.
  • the nested position of chair 102 includes a rotation of seat 108 toward seatback 106, such as, for example, a rotation of seat 108 to a substantially vertical orientation.
  • the nested position of tablet arm 100 includes a rotation of tablet 104 away from stop member 222, as well as a swiveling of support member 112 along axis 206 toward seatback 106.
  • tablet 104 is rotated away from stop member 222 until tablet 104 contacts tablet stop 1328; according to other embodiments, tablet 104 is rotated away from stop member 222 through a smaller rotation angle.
  • support member 112 may be swiveled toward seatback 106 until stop member 222 contacts seat back as depicted in FIG. 7; according to other embodiments, support member 112 is stopped short of stop member 222 contacting seatback 106.
  • tablet 104 may rest above seatback 106 as depicted in FIG. 7; according other embodiments, tablet 104 may rest above and contact seatback 106.
  • FIGS. 9-11 illustrate how two chairs 102 may be nested and stored according to embodiments of the present invention.
  • Multiple chairs 102 may be nested and/or stored in this fashion, with each chair 102 occupying significantly less area space on average in the nested configuration than in the operable position.
  • a nesting chair 102 with a nesting tablet arm 100 may also be nested with a regular nesting chair 102 lacking a nesting tablet arm 100.
  • various such combinations of nesting chairs with and/or without nesting tablet arms 100 may be nested together to save space.
  • FIGS. 12-14 depict exploded views of tablet arm 100, illustrating how tablet arm 100 may be made according to various embodiments of the present invention.
  • Tablet 104 is slidably and rotatably coupled with support member 112 by collars 302, according to some embodiments of the present invention.
  • Support member 112 may include a horizontal section 1330 and a vertical section 1332, and according to some embodiments in which horizontal section 1330 is tubular, an end cap 1308 may be placed at an end of horizontal section 1330.
  • Collars 302 may include an outer collar section 302b, an inner collar section 302c, and a collar attachment tongue 302a with holes 302d.
  • Inner collar section 302b and outer collar section 302c may be injection-molded plastic components which snap together around horizontal section 1330, for example.
  • collar attachment tongue 302a may be placed over both collar sections 302b, 302c and attached to tablet 104.
  • Collar attachment tongue 302a may be attached to tablet 104 via bolts 1336 applied through holes 302d and into attachment holes 1334.
  • collar attachment tongue 302a may be attached to tablet 104 via screws, nails, staples, adhesive, welding, or other suitable attachment means.
  • Collar attachment tongue 302a is held to tablet 104 with a force sufficient to maintain attachment between collar attachment tongue 302a and tablet 104 and to maintain a relatively fixed position of collar sections 302b, 302c with respect to tablet 104, while permitting collar sections 302b, 302c to rotate and slide with respect to horizontal section 1330.
  • FIG. 13 depicts forward and rear collars 302.
  • the forward collar 302 couples horizontal section 1332 to tablet 104 in a location between a front stop 1302 and a rear stop 1304.
  • Front stop 1302 and rear stop 1304 serve to limit horizontal sliding of tablet 104 along horizontal section 1330.
  • the sliding or translational distance of tablet 104 along horizontal section 1330 achievable by a particular embodiment of the present invention may be calculated by measuring a distance between front stop 1302 and rear stop 1304 along horizontal section 1330, then subtracting the width of the forward collar 302. According to some embodiments of the present invention, such sliding or translational distance of tablet 104 is between two and four inches.
  • forward stop 1302 and rear stop 1304 are depicted as pegs or bars protruding from horizontal section 1330 according to embodiments of the present invention, stops 1302 and 1304 may alternatively be bumps, ridges, collars, bends, lips, or other irregularity coupled with or formed on horizontal section 1330 and configured to halt sliding of forward collar 302.
  • front stop 1302 and rear stop 1304 are connected by a crossbar 1306, such that stop member 222 is a U-shaped bracket that may be coupled with horizontal section 1330 such as, for example, by welding.
  • forward collar 302 may be attached over horizontal section 1330 at any point between front stop 1302 and rear stop 1304.
  • a rearward collar 302 may be included for further stability.
  • Collar section 302c may be flat on top as illustrated in FIG. 13 to permit tablet 104 to rest flatly against collar section 302c.
  • Stop member 222 may be coupled with horizontal section 1330 in a configuration which permits tablet 104 to rest flatly against both collar sections 302c and crossbar 1306 when tablet arm 100 is in the operable position; according to some embodiments, a slight upward angle of stop member 222 with respect to horizontal section 1330 may achieve this purpose, as seen from the front view of FIG. 2.
  • FIGS. 13 and 14 also illustrate a swivel coupling between support member 112 and support member 110, according to some embodiments of the present invention.
  • the vertical section 1332 of swiveling support member 112 includes slots 1326a, 1326b formed within vertical section 1332.
  • a sleeve 1312 is configured to surround at least part of vertical section 1332; sleeve 1312 is further configured for insertion into a sleeve receptacle 1310 coupled with and/or protruding from fixed support member 110.
  • sleeve receptacle 1310 extends substantially vertically from an end of support member 110.
  • Sleeve receptacle 1310 includes threaded holes 1404a, 1404b sized for threadable interface with threaded pins 1316a, 1316b.
  • sleeve 1312 may be made with two identical injection-molded plastic pieces 1312a, 1312b configured to snap together and/or be otherwise coupled around lower end of vertical section 1332.
  • Holes 1314a, 1314b formed in sleeve half 1312a may be similar or identical to holes 1402a, 1402b formed in sleeve half 1312b, according to some embodiments of the present invention, and may be sized to permit threaded pins 1316a, 1316b to pass therethrough.
  • sleeve 1312 may be placed around at least part of vertical section 1332 such that holes 1402a, 1402b approximately align with slots 1326a, 1326b, respectively.
  • bottom end 1318 of vertical section 1332 may contact bottom 1324 of sleeve 1312 for further vertical support.
  • Sleeve 1312 may be placed into sleeve receptacle 1310, such that protruding lip 1320 of sleeve 1312 rests upon top ledge 1322 of sleeve receptacle; such a configuration may permit weight applied to tablet 104 to be further distributed through sleeve 1312, protruding lip 1320, and sleeve receptacle 1310 instead of exclusively through slots 1326a, 1326b to pins 1316a, 1316b.
  • Threaded pin 1316a may be threaded through hole 1404a until threaded pin 1316a also passes through hole 1402a in sleeve 1312 and into slot 1326a in vertical section 1332, while being held in a fixed position with respect to sleeve receptacle 1310 by the threaded connection between sleeve receptacle 1310 and pin 1316a.
  • Threaded pin 1316b may be threaded through hole 1404b until threaded pin 1316b also passes through hole 1402b in sleeve 1312 and into slot 1326b in vertical section 1332, while being held in a fixed position with respect to sleeve receptacle 1310 by the threaded connection between sleeve receptacle 1310 and pin 1316b.
  • threaded pins 1316a, 1316b are fixed relative to sleeve receptacle 1310, which is fixed relative to support member 110 and thus relative to nesting chair 102. Because threaded pins 1316a, 1316b also pass through holes 1402a, 1402b, sleeve 1312 is also prevented from rotating substantially with respect to sleeve receptacle 1310. However, vertical section 1332 may freely rotate within sleeve 1312 limited only by the extent of slots 1326a, 1326b.
  • Support member 112 may be swiveled in one direction until threaded pins 1316a, 1316b contact an end of each slot 1326a, 1326b, thus halting rotation in that one direction. Support member 112 may also be swiveled in the opposite direction until threaded pins 1316a, 1316b contact another end of each slot 1326a, 1326b, thus halting rotation in that opposite direction.
  • the angle through which support member 112 may swivel in a substantially horizontal plane is directly related to the angular extent of slots 1326a, 1326b formed within vertical section 1332, according to embodiments of the present invention.
  • slots 1326a, 1326b are of sufficient extent and placement to permit swiveling of tablet arm 100 toward seatback 106 into the nesting position as shown in FIGS. 5-8, and to permit swiveling of tablet arm 100 away from seatback 106 by an angle as measured between seatback 106 and horizontal section 1330.
  • This angle as measured between seatback 106 and horizontal section 1330 about axis 206, may be a predetermined angle at which swiveling of second support member 112 may be halted.
  • such angle may be approximately 90 degrees, corresponding to the horizontal section 1330 pointing straight forward.
  • such angle may be between 90 and 180 degrees, such as, for example, 120 degrees so that tablet 104 may be pushed slightly toward the side of chair 102 to permit easier access for sitting down on or standing up from chair 102.
