Abstract
A swiveling folding chair is provided. The chair swivels independently of the legs of the chair. The chair includes audio speakers exterior of the back support of the chair.
Claims2
A folding chair comprising
- (a) a primary control tree including
- (i) a first control member including an elongate shaft, said shaft including
- an elongate centerline,
- an upper end,
- a lower end, and
- a central section intermediate said upper end and said lower end,
- (ii) a first control collar including
- an upwardly extending body, and
- a first aperture formed therethrough, said collar mounted on said control member with said shaft slidably extending through said first aperture,
- (iii) a second control collar with a second aperture formed therethrough and mounted on said first control member and said first control collar with said body slidably extending through said second aperture to
- move along said shaft simultaneously with said first control collar, and
- rotate about said body and centerline independently of said first control collar,
- (iii) a third control collar mounted on said upper end of said shaft to rotate about said centerline, and
- (iv) a fourth control collar mounted on said lower end of said shaft;
- (b) at least three legs each including a proximate end pivotally attached to said first control collar;
- (c) at least two upwardly extending support arms each including a proximate end pivotally attached to said second control collar;:
- (d) a pliable foldable fabric seat structure attached to said support arms and including a horizontally oriented seat and a vertically oriented backing extending upwardly from said seat, said backing including a back support area and at least one outlying portion extending outwardly from said back support area;
- (e) an audio speaker mounted in said outlying portion;
- (f) an amplifier operatively associated with said audio speaker and adapted to
- (i) be connected to and to receive and amplify audio signals from a portable media device, and
- (ii) transmit amplified audio signals to said audio speaker;
- (g) at least three elongate support members each operatively associated with a different one of said legs and including a first distal end pivotally attached to said one of said legs and a second proximate end pivotally attached to said fourth control collar;
- (h) at least three elongate brace members each operatively associated with a different one of said arms and including a primary distal end pivotally attached to said different one of said arms and a secondary proximate end pivotally attached to said third control collar;
- said shaft slidable through said first aperture between at least two operative positions,
- (i) a first operative position with
- (i) said chair stowed and folded,
- (ii) said fourth control collar upwardly displaced toward said first control collar such that said second proximate ends are positioned above said first distal ends,
- (iii) said third control collar upwardly displaced away from said first control collar such that said secondary proximate ends are positioned above said primary distal ends, and
- (j) a second operative position with
- (i) said chair deployed and unfolded,
- (ii) said fourth control collar downwardly displaced away from said first control collar such that said second proximate ends are generally positioned level with or below said first distal ends, and
- (iii) said third control collar downwardly displaced toward said first control collar such that said secondary proximate ends are generally positioned level with or below said primary distal ends.
