Claims18
Suspended seating apparatus including, in combination, an upstanding post having an upper end and a lower end, a composite arm having a first member secured to and laterally extending from said upper end and a second member secured to, axially extending from, and telescopingly engaged with respect to said first member, a vertically aligned journal box secured to said second member, at least one chair support arm depending from and journaled for vertical axis rotational displacement with respect to said journal box, structure secured to said chair support arm and constructed for supporting attachment to selected external seating structure, and extensible base support structure secured to said post at said lower end and projecting laterally outwardly vertically underneath said composite arm and also said journal box a distance from said post at least as great as the distance of said journal box from said post, whereby to lend fulcrum-like support to said apparatus against load-imposed outward tipping tendencies.
Suspended seating apparatus including, in combination, an upstanding post having an upper end and a lower end, a composite arm having a first member secured to and laterally extending from said upper end and a second member secured to, axially extending from, and telescopingly engaged with respect to said first member, a first journal box secured to said second member, at least one hollow chair support arm depending from and journaled for axial rotational displacement about a vertical axis with respect to said first journal box, said chair support arm being provided with a seat plate having a depending hollow shaft provided an interior, transversely mounted first cross-pin anchor, a second journal box secured to an extremity of said chair support arm and journalling said depending hollow shaft, a first torsion-operative return-spring means, having an upper looped end hooked over said cross-pin anchor and a lower curved end keyed to and retained by said second journal box, intercoupling said shaft with said second journal box, whereby to return, by the transverse torsional movement of said spring means, said seat plate to a desired position when not in supportive use, a lower hollow portion of said second journal box having downwardly facing keyway slots, an upstanding triangular retainer key seated in said slots and having an aperture retentively receiving said lower curved end of said turn spring means, whereby said lower curved end is in fact keyed to and retained by said second journal box as aforesaid, and base support structure secured to said post at said lower end and extending laterally outwardly underneath said composite arm, whereby to lend support to said apparatus.
Suspended seating apparatus including, in combination, an upstanding post having an upper end and a lower end, a composite arm having a first member secured to and laterally extending from said upper end and a second member secured to, axially extending from, and telescopingly engaged with respect to said first member, a journal box secured to said second member, at least one chair support arm secured to, depending from, and journaled for axial rotational displacement about a vertical axis with respect to said journal box, structure secured to said chair support arm and constructed for supporting attachment to selected external seating structure, and base support structure secured to said post at said lower end and projecting laterally outwardly for positionment vertically underneath said composite arm and said journal box, whereby to lend fulcrum-like support to said apparatus, said base support structure including an outwardly and laterally extending tubular receptacle of transverse square cross-section, a base arm extension telescoping with respect to and within said tubular receptacle and being of complementary square cross-section, means for fixing the disposition of and extension within said tubular receptacle by said base arm extension, and laterally and oppositely extending cross arm structure secured to said base arm extension, said base arm extension and tubular receptacle being constructed and arranged, through ninety-degree mutual rotative displacement, for enabling both horizontal and, alternately, upstanding disposition of said cross arm structure as to be parallel with said post, whereby to condition said structure for stackable shipping condition.
Suspended seating apparatus including, in combination, an upstanding post, elongated cantilever structure secured to an upper portion of said post, base support structure positioned vertically beneath said cantilever structure and secured to a lower portion of said post, and a support-seat arm having an upper essentially vertical portion, vertically positioned above said base support structure and journalled to said cantilever structure for axially vertical rotative movement, and also an outwardly extending lower portion, and person-support means secured to said outwardly extending lower portion, said support-seat arm being positioned between said cantilever structure and said base support structure.
Suspended seating apparatus including, in combination, an upstanding post, an extensible upper arm structure secured to an upper portion of said post, an extensible base support structure secured to a lower portion of said upstanding post, said upper arm structure including an outer extremity journal box means constructed for receiving, for axial rotational displacement about a vertical axis, at least one depending seat support arm, said extensible base support structure including a toe essentially defining a fulcrum positionable, relative to said upstanding post, at least as far from said post as said journal box means.
