Hector - Web page: https://patentgrep.com/patent/US20140191546A1 ## CPC - A47C 3/045: {with tipping-up seats} - A47C 7/006: {with castors} - A47C: CHAIRS; SOFAS; BEDS ## Abstract A stackable and nestable chair includes a seat assembly, a pair of rear legs spaced apart by a first distance, and a pair of front legs spaced apart by a second distance different than the first distance. The front legs and the rear legs mutually connected by a crossbar, and the seat assembly is supported by the crossbar when the seat is in an operable position. A plurality of casters are each attached to a bottom of each of the front and rear legs, wherein each caster includes a notch that is configured to couple with a leg of an adjacently stacked chair. ## Claims ### Claim at position 1 1-29. (canceled) ### Claim 30 A vertically stackable and horizontally nestable chair comprising: a set of legs that include a pair of rear legs spaced apart by a first distance and a pair of front legs spaced apart by a second distance different than the first distance; a seat rotatably secured to two of the legs of the set of legs, the seat having a primary surface adapted to support a sitting user; the vertically stackable and horizontally nestable chair having a first upright configuration in which the seat is in a first position, the first upright configuration being an operable configuration in which the primary surface of the seat is oriented to permit a user to sit upon it; and the vertically stackable and horizontally nestable chair having a second upright configuration in which the seat has rotated to a second position, the second upright configuration being a stackable and nestable configuration in which the vertically stackable and horizontally nestable chair is simultaneously vertically stackable and horizontally nestable with another vertically stackable and horizontally nestable chair in the second upright configuration. ### Claim 31 (depends on 30) The vertically stackable and horizontally nestable chair of claim 30, further comprising: a pair of arms, each arm being continuous with one of the rear legs, wherein each arm is downwardly sloped from a back portion to a front portion, and wherein the pair of rear legs are more closely spaced apart than the pair of arms. ### Claim 32 (depends on 31) The vertically stackable and horizontally nestable chair of claim 31, wherein the pair of arms are configured to be substantially parallel with a pair of arms of an adjacently nested vertically stackable and horizontally nestable chair. ### Claim 33 (depends on 31) The vertically stackable and horizontally nestable chair of claim 31, wherein each arm and continuous rear leg is substantially L-shaped. ### Claim 34 (depends on 30) The vertically stackable and horizontally nestable chair of claim 30, further comprising: a pair of spacers, each spacer of the pair of spacers being attached to a rear leg of the pair of rear legs, the spacers being positioned to engage a rear leg of an adjacently stacked vertically stackable and nestable chair. ### Claim 35 (depends on 34) The vertically stackable and horizontally nestable chair of claim 34, wherein each rear leg includes a rear leg cap, and wherein each spacer of the pair of spacers is positioned to engage a rear leg cap of an adjacently stacked vertically stackable and nestable chair. ### Claim 36 (depends on 30) The vertically stackable and horizontally nestable chair of claim 30, wherein the vertically stackable and horizontally nestable chair has a first footprint, wherein a stack of a plurality of vertically stackable and horizontally nestable chairs has a second footprint, and wherein the first and second footprints are substantially the same. ### Claim 37 A first stackable and nestable chair comprising: a leg assembly including two front legs and two rear legs, the front legs being connected to the rear legs by a crossbar, wherein the two rear legs are spaced apart by a first distance and the two front legs are spaced apart by a second distance less than the first distance; a seat having a primary sitting surface and being pivotally mounted to the crossbar, the seat being configured to rotate between an operable position and a collapsed position, wherein the seat is supported by the crossbar and is oriented to permit a user to sit upon the primary sitting surface in the operable position; wherein the leg assembly and seat are configured such that, when the seat is in the collapsed position, the stackable and nestable chair is capable of being simultaneously arranged in a stacked assembly with a second stackable and nestable chair and a nested assembly with a third stackable and nestable chair. ### Claim 38 (depends on 37) The first stackable and nestable chair of claim 37, wherein the stackable and nestable chair is capable of being simultaneously arranged in a vertically stacked assembly with the second stackable and nestable chair and a horizontally nested assembly with the third stackable and nestable chair when the seat is in the collapsed position. ### Claim 39 (depends on 37) The first stackable and nestable chair of claim 37, further comprising: a pair of arms that are continuous with the rear legs, wherein each arm is downwardly sloped from a back portion to a forward portion. ### Claim 40 (depends on 39) The first stackable and nestable chair of claim 39, wherein the back portion of each arm is configured to contact a forward portion of a corresponding arm of the third stackable and nestable chair. ### Claim 41 (depends on 39) The first stackable and nestable chair of claim 39, wherein the forward portion of each arm is configured to contact a back portion of a corresponding arm of the third stackable and nestable chair ### Claim 42 (depends on 39) The first stackable and nestable chair of claim 39, wherein the pair of arms are configured to be substantially parallel with a pair of arms of the third stackable and nestable chair. ### Claim 43 (depends on 37) The first stackable and nestable chair of claim 37, wherein a stack of stackable and nestable chairs is nestable with another stack of stackable and nestable chairs. ### Claim 44 A stackable and nestable chair comprising: a pair of rear legs spaced apart by a first distance and configured to contact a ground surface in an operable configuration; a pair of front legs spaced apart by a second distance; a seat configured to rotate between an operable position and a collapsed position; and a pair of fixed arms that are coupled to the rear legs, wherein the pair of fixed arms are spaced apart by a third distance greater than the first distance, wherein, when the seat is in the collapsed position, the seat, rear legs, front legs, and arms enable the stackable and nestable chair to simultaneously nest with a first similarly configured stackable and nestable chair in the operable configuration and stack with a second similarly configured stackable and nestable chair. ### Claim 45 (depends on 44) The stackable and nestable chair of claim 44, wherein, when the seat is in the collapsed position, the front legs are configured to pass between rear legs of the first similarly configured stackable and nestable chair. ### Claim 46 (depends on 44) The stackable and nestable chair of claim 44, wherein, when the seat is in the collapsed position and when the pair of rear contact the ground surface, the seat, rear legs, front legs, and arms enable the stackable and nestable chair to simultaneously nest with the first similarly configured stackable and nestable chair in the operable configuration and stack with the second similarly configured stackable and nestable chair. ### Claim 47 (depends on 44) The stackable and nestable chair of claim 44, wherein the pair of fixed arms are configured to be substantially parallel with a pair of fixed arms of the first similarly configured stackable and nestable chair. ### Claim 48 (depends on 47) The stackable and nestable chair of claim 47, wherein the arms are downwardly sloped from a back to a front of the chair. ### Claim 49 (depends on 47) The stackable and nestable chair of claim 47, wherein the arms include curved portions that transition from the second distance apart proximate the rear legs to a third distance apart at an armrest portion of the arms, wherein the third distance is greater than the second distance.
