Definitions
- Chairs embodying the invention may be stacked individually or in assembled multiple sets.
- the legs interlock with each other to position stacked chairs against fore-and-aft displacement and, desirably, the frames interlock with the backs of chairs on which they are respectively superimposed, both forms of interlock being achieved regardless of whether the individual units are being stacked or whether chairs assembled in sets are being stacked with like sets of chairs.

ATTOZNEY! United States Patent a 203 731 MULTIPLE SEATING, rNcLtmiNG STACKABLE CHAIRS WITH FOLDING BACKS Allison F. Krueger, Green Bay, Wis., assignor to Krueger This invention relates to multiple seating including stackable chairs with folding backs.
Chairs embodying the invention may be stacked individually or in assembled multiple sets. In any case, the legs interlock with each other to position stacked chairs against fore-and-aft displacement and, desirably, the frames interlock with the backs of chairs on which they are respectively superimposed, both forms of interlock being achieved regardless of whether the individual units are being stacked or whether chairs assembled in sets are being stacked with like sets of chairs.
Seats and backs have stop hinges pivotally connecting them with each other. In perferred embodiments, the stop hinges not only limit the pivotal movement of the back beyond a desired position of use but also limit the pressure resulting from stacking after the back has been pivoted toward the seat. This avoids undue pressure of .the back upholstery upon the seat upholstery when the chairs are stacked.
The subassembly of a pivotally connected seat and back is desirably of less width than a rigid frame to which the legs are attached. The frame includes generally parallel side members with which the legs are in rigid connection, and cross members preferably disposed between the ends of the side members. The sides of the seat and back are preferably not parallel but are forwardly convergent, the stop hinges being correspondingly angled so that the pivotally connected portions thereof have relative movements in planes parallel to the side members. When the chairs are assembled in sets or gangs of chairs, they may conveniently be connected with each other by means of bars which extend beneath the assembled chairs for the width of the set, and are anchored to the frames of inindividual chairs by means of clips engaging the exposed side members of the respective chair frames.

Patented Aug. 31, 1965 "ice FIG. 10 is a plan view on a reduced scale showing chairs embodying the invention as they appear when assembled in a set or gang of chairs.
FIG. 11 is a fragmentary detail view taken on an enlarged scale on the line l.1-11 of FIG. 10.
FIG. 12 is a fragmentary detail view on an enlarged scale taken on the line 1212 of FIG. 10.
Each chair embodying the invention preferably comprises a frame generically designated by reference character 14 and comprising side members 16 and 18 which are generally parallel to each other and supported on forward legs 20 and rear legs 22. The forward and rear legs are preferably divergent, the divergence being partially attributable to the rearward inclination of the frame members 16 and 18 as best shown in FIG. 2, and partially due to the obtuse angle 24 between the respective rear legs and the respective frame member.
The frames 14 of the respective chairs further include transverse members 26 and 28 which are welded or otherwise secured to the side members 16 and 18, preferably intermediate the ends thereof, as clearly appears in FIGS. 3 and 4.
Fixed to the transverse frame members 26, 28 is a subcombination comprising seat and back elements of like contour and in hinged connection with each other. Each such seat element 30 is desirably prefabricated to constitute a metal pan 32 with rolled or beaded sides at 34 that retain padded upholstery 36. The structure may include a wooden base 76 upon which there is a sponge rubber pad 78 about which the upholstery or other covering is wrapped as shown in FIG. 7. The seat is of lesser width than the frame 14, the side margins thereof prefferably being forwardly convergent to lie between the side members 16 and 18 of the frame. The pan 32, which constitutes the bottom of the seat, may be anchored by bolts 74 to the transverse members 26, 28 of the frame.
The back 40 may comprise a pan 42 like that which provides the seat and having similar lateral beads at 44 from which the padded upholstery 46 projects as above described. Seat and back elements may be identical.
The back 40 is hingedly connected with the rear of the seat 36) and is preferably dependent thereon for position. The hinged connection is preferably effected by means of hinges best illustrated separately in FIG. 8 at 50. Each such hinge includes a strap 52 connected by spot welds 54 to the side of the seat. The hinge flange 56 is connected to the bottom of the seat as by welds 57 shown in FIG. 4. Each such hinge further includes a strap 58 welded to the seat back 40 by a spot weld or welds 60. A pintle bolt or rivet 62 pivotally connects strap 58 with strap 52 of each such hinge.
The portion of strap 52 in which the pintle 62 is located may be somewhat broadened at 64 and provided with a channel shaped stop flange 66 which overhangs the move-.
downwardly upon the pintle 62 to the folded position shown in FIG. 5 wherein the back is superimposed on the seat. The position of strap 58 will then be as indicated in dotted lines in FIG. 8. It will rest on the end 70 of the stop flange 66 to hold the seat back in a position in which it will be substantially parallel with the seat, undue compression of the padding and undue friction of the back upholstery 46 upon the seat upholstery 36 being revented by this stop flange contact. In this position of the parts, the pan portion 42 of the folded back is exposed to receive and support bumpers 72 which are disposed on the undersides of the transverse frame elements 26 and 28 as best shown in FIGS. 2, 4, 5 and 7. These bumpers may be mounted on the bolts 74 threadedly engaged with nuts 76 welded to the pan portions 34 of the respective seats and thereby serving to connect the seats detachably to the respective transverse frame members 26 and 28.
FIG. 9 shows a different stop hinge arrangement employing straps 520 and 580 connected together by pintle 620, the sto member 660 being carried, in this instance, by the strap member 580 to engage the rear margin 7 09 of the strap member 520. This stop hinge is effective to hold the back in the desired position of use, but it offers no stop to limit the folding movement of the back onto the seat. This imposes the weight of superimposed chairs directly upon the seat and back cushions of underlying chairs.
Reference has been made to the bumpers 72 which support the weight of a superimposed chair upon the folded back of a chair therebeneath. In addition to these bumpers, we preferably provide bumpers at 80 on the inner sides of respective legs. In the nested positions of the chairs, these bumpers engage the outside surfaces of the legs of underlying chairs as best shown in FIG. 1. Also, as a means of aligning the superimposed chairs against lateral displacement, the respective transverse frame members, or at least the forward frame members 26, are desirably provided with padded or plastic covered fingers at 84 which register with, and engage the sides of, the flanges or beads 34 of underlying chairs in the manner clearly shown in FIGS. 6 and 7.
A row of chairs can be connected as a unitary set or gang in the manner shown in FIGS. 10 to 12. This may conveniently be done by extending a bar or bars 86 transversely beneath any given number of chairs in a row. FIG. 10 shows four chairs thus connected unitarily. Intermediate the ends of the row the proximate side frame members 16 of one chair and 18 of an adjacent chair are engaged by a clip 88 which is clamped thereon by means of a bolt 90 extending between the respective chairs into threaded connection with a nut 92 fixed to the bar 86. At the ends of the row a modified Clip 94 is similarly connected to the frame member 18 of the terminal bar by means of a similar bolt 90 as shown in FIG. 12. A set i of chairs thus connected in a row of any length for which the connecting bar is provided may be handled unitarily and stacked unitarily. The backs may be raised and lowered individually when the chairs are unstacked.
