if, age/vir United States atent CHAR CONSTRUCTION Earl D. Smith, Indianapolis, Ind. Application November 22, 1952, Serial No. 321,983 8 Claims. (Cl. 155-191) This invention relates to an article of furniture, particularly to a seat or chair construction.
The invention has particular reference to articles of furniture, such as seats, chairs, settees, etc., formed of comparatively light inexpensive material, such as heavy cardboard, corrugated bre board or the like, the present invention involving improvements upon the construction disclosed in my copending application Serial No. 189,865, tiled October 12, 195() now Patent No. 2,707,514, granted May 3, 1955.
The present invention, while involving general principles disclosed by my copending application, brings about an article of furniture which may be readily assembled by those ordinarily unfamiliar with such procedures which accomplishes a rigidity in its final or set-up form impossible of attainment in the structure disclosed by my copending application and which involves the use of a minimum of separate parts in its completed structure.
A further object of the invention is to provide a seat or chair structure involving prefabricated parts capable of being folded `upon one another in such manner as to compose a comparatively small, light and compact package in knock-down form, the advantages of which are obvious, and which may be readily set-up and the parts easily but securely locked together by simple and efficient means to provide a strong, durable and yet extremely light seat or chair structure.

The structure disclosed by Figs. 1 to 9 inclusive is a chair involving integral seat and back rest portions without arms'. The body or frame is cut from a single blank of relatively thin corrugated or ibre board; the configuration of the blank and the scorings thereon enabling the same to be properly bent or folded part upon part and so interlocked as when in properly set-up position to provide a substantially rigid bottom or seat portion with an integral back equally as rigid and strong. The frame has arranged therein risers, webs or panels, formed preferably of the same material of which the body is constructed, and so interlocked with parts of the frame and other elements involved in the completed structure as to be maintained in sturdy upright position to bear generally the weights and stresses to which the article of furniture will be subjected. Moreover, the body frame and the several parts which go together in the completed article of furniture are so assembled and tied in with one another as to resist and sustain any lateral strains to which the furniture piece may be exposed.
In carrying out this form of the invention,`the blank is so cut as to provide a back section or panel 20, side sections 21, and to one of the latter is attached the end panel or section 22.
As will be observed from Fig. 3, the back section or panel is of substantially rectangular form, the sides of which are dened by the lines of scoring indicated at 23 and separating the said panel from the said side elements. The upper end of this back section is provided with three lines of spaced parallel transverse scorings indicated a't 24, 25 and 26 respectively, the line of scoring 26 deiining the connecting line with the flap 27 having inwardly extending spaced parallel slots 28. The opposite end of the back is provided with transverse spaced scoring lines 29 and 30, the space between the said lines providing a bottom panel member 31. The end element 32 constitutes a spacer member or web having spaced parallel slots 33 extending inwardly from the extreme outer edge thereof a predetermined distance and in parallel alignment with the recesses 28 at the opposite end of this panel member.
The side members 21, as has been heretofore stated, connect with the back member 20 upon the parallel scored lines 23, and each of said side members carries a bottom flap 34 connected with the end members by the scoring lines 35. These iiaps extend throughout the width of the end panels, each being of a breadth substantially equal to one half the width of the chain bottom. Each of these bottom Hap members has projectin'gfrom itsY outer edges locking tabs 36 connected toV their respective flaps by the scoring lines 37.
The opposite or forward portions of the side panels 21 are scored on lines 3S and 39 to provide wings 40 and 41 respectively, foldable upon the said lines. The aps 4@ and 41 are each provided in their outer or forward edges with tabs 42-43 for purposes to be hereafter detailed. Each of the end sections at its upper portion and near its juncture wi-th the back section 20 is also provided with a tab 44 constituting a top side lock 'foldable upon the scoring line 45.
The end panel 22 is connected with the adjacent side member 21 along the scoring line 46, the said scoring line being parallel with scorings 23. This panel is also scored along line 47, the said scoring line being in alignment with scorings 35 of the side panels and 29 of the back member. The flap 4S provided by the line of scoring 47 constitutes a bottom flap and is provided with a substantially centrally arranged opening 49 disposed transversely thereof.
The end panel 22 near its opposite side is provided with spaced parallel lines of scoring 50 and 51, the same being parallel with the line of sco-ring 47, the space between scoring lines 50-51 providing a front seat brace 52. The flap 53 beyond the line of scoring 51 constitutes a web provided with spaced parallel slots 54 extending inwardly from the free end of the said web.
The blank here described, when properly folded or bent along the lines of fold as will be hereinafter set forth, constitutes the main 'frame or housing for the seat structure. lt will be observed that the lines of scoring 38 and 39 of the side wings define the planes of the seat and back supports of the chair when in proper setup position. These lines of scoring will be at such angles relative to one another as Ito provide a proper inclination to the seat as well as the back to aiford an easy and comfortable reclining position for the chain occupant.
The frame here described receives in spaced parallelisrn a plurality of web members S5, as shown more in detail in Figs. 4 and 9 of the drawings. These web members may be single plies of relatively thin corrugated or iibre board, or may be of double thickness to lend additional strength and rigidity to the structure. These web members, in side elevation, are of substantially the same configuration and size as the side panels by the scoring lines 23, 35, 33 and 39. Each of the web members thus provides a back rest edge indicated at 56 and a seat supporting edge 57 both having inclinations corresponding to the lines of 'fold 39 and 3S respectively of the side panels.V Any number of web members S may be employed in the chair construction, four being employed in the present instance. Each of these web members has provided therein slots 553 extending inwardly from the seating edge 57 a predetermined distance and perpendicular -to the bottom edge 59 of the said web members. Each of the web members, near the rear and bottom thereof, also is provided with an inwardly extending slot ed disposed perpendicular to the bottom edge 59, While a similar slot 6i extends inwardly of the back supporting edge Se of each web member near the top ythereof and perpendicular to the said edge 56.
Figs. 5 and 6 of the drawing illustrate ller members to be used in the chair assembly to constitute the seat portion thereof to sustain the chair occupant. The i'lller member of Fig. 5 is formed of `the same material of which the other parts heretofore described are constructed, is of rectangular form of substantially the proportions shown, and is provided near its mid-portion with transverse lines of scoring indicated at 62'. These defined 4 1 f lines of scoring provide a transverse mid-portion or seat brace indicated at 63, and at a point substantially midway the sides of said member is a transverse slot indicated at 64. The wings, arms or webs 65 lying outside the scoring line 62 are each provided with spaced parallel slots 66 entering from the free ends thereof and the slots of these webs are in longitudinal alignment with one another.
The liller member or support of Fig. 6 is also of rectangular shape having transverse lines of scoring 67 to define a mid portion brace or seat element 68 with lateral wings or webs 69 also provided in their outer edges with slots 76; the slots at one end o'f the filler being aligned with those in the opposite end.
Another element utilized in the improved chair iconstruction is the backing element shown in Fig. 7. This element comprises a panel to constitute a backing sheet 71 to rest against the forward edges 56 of the web members 55. The main body of this backing sheet is provided near its upper end with a transverse scoring line 72 providing a ap 73 between the said line and the adjacent end of the sheet. This flap 73 is provided with spaced parallel slots 74 extending inwardly from the free edge thereof a predetermined distance. These slots correspond in number and in spacing with the web members 55, also with the slots 28 of the front flap, 33 of the bottom web 22, 66 of the filler member of Fig. 5, and 79 of the filler of Fig. 6. The backing sheet 7l is also provided near its opposite end with a pair of spaced parallel transverse scoring lines 7S and 76 providing between them a seat element represented at 77. That end of the backing sheet beyond the line of scoring 76 constitutes a web 78 having slots 79 extending inwardly from the free end thereof. These slots 79, it will be observed, are aligned with the slots 74 at the opposite end of the backing sheet or panel, and are equal in number and spacing with the web members 55.
In assembling the chair structure, the blank shown in Fig. 3 is folded or bent along the lines of scoring 23 until the side panels 2l are disposed at substantially right angles to the back 4section 2t). The end panel 22 will then be bent along its line of scoring 46 until it is disposed at right angles to its supporting section 21, the outer end of the said panel being secured in any desired manner to the ilap 81 on the free end of the companion side panel 21. The bottom panel section 48 carried by the end panel 22 will then be bent along its line of scoring 47 at right angles so as to constitute a part of the chair bottom. The bottom panel member 31 is then bent along the scoring line 29 within the frame until the panel 31 is at right angles to the back Ztl. The web 32 attached to the bottom panel 30 is then bent along the scoring line until it is perpendicular with the bottom panel 31. The bottom flaps 34 will then be bent along the scoring line until they are at right angles to their supporting side sections 21 with their free edges in meeting engagement in the median line of the frame, whereupon the tabs 36 are bent upwardly along their lines of scoring 37. Those tabs 36 adjacent to the rear end of the chair will pass through the transverse slot 8@ in the bottom panel member 30 to assist in securing the bottom aps 34 iirrnly in position as well as to hold the bottom panel member 3@ in proper position. r[he tabs 36 near the opposite end of said bottom ilaps will coincide with and extend through the transverse slot 49 constituting a part of the end panel 22 to thus lock these elements securely together. The substantially L`shaped web members are then inserted in spaced parallel relationship longitudinally within the frame. The slots or recesses 64) near the rear end of each web member interengage with the slots or recesses 33 in the upstanding web member 32 near the adjacent end of the frame. The top of the back member 20 is then bent along its lines of fold 24, 25 and 26. The strip delined by fold lines 24 and 25 overlies the upper edges 55 of the web members 5S, While the panel between fold lines 25-26 overlies the portions 552 of the front edges 56 of the web members, while the flap 27 extends inwardly of the edge 56 with its slots 28 in interlocking engagement with the slots 61 in the adjacent edges f the web members S5. It will be understood that the frictional contact between these various elements will hold them securely together and against casual displacement. Y
The panel 52 forming a part of end panel 22 is then bent inwardly along the line of fold 50 until it lies in at contact with and is supported by the upper edges of the spaced web members 55. The web 53 is bent downwardly along fold line 51 with the slots 54 in the outer edge thereof in interlocking engagement with the adjacent slots 58 in the upper edges of the web members 55. It will be understood that the length of the web from its fold line 51 to the extreme end of the web equals the distance between the upper edges of the webs 55 and the bottom of the said webs at the outermost recess or slot 58'. The slots 54 and 58 rare of such depth as to enable these cooperating webs to intertt -or interengage with one another and to equally sustain between them such weights or pressures as are transmitted to the chair seat. The ller member illustrated in Fig. is then bent along its lines of fold 62 into substantially inverted U-shape. The width of the panel portion 63 of this filler member is substantially equal to the distance between slots 58 in the web members 55, and the webs 65 of the said filler member are then passed downwardly so as to receive the spaced slots 58 `of the web member 55. It will be understood that when properly inserted the panel portion 63 of the filler member will rest upon the upper edges of the web members 55 and the lower edges of the webs 65 of the filler member will rest upon the bottom of the frame. The back panel member shown in Fig. 7 is then applied. The upper end of this panel is bent along its line of fold 72 so that the ap portion 73 thereof is disposed in substantially right 'angles to the body of the back brace and the recesses or slots 74 are forced into interlocking engagement within recesses or slots 61 in the upper and forward edges of the web members 55. F[he body portion 71 of this back panel lies flush against and is supported by the inclined forward edges 56 of the web members. The line of fold 75 in the back panel occurs at the juncture of the edges 56-57 of the web members, and the panel portion 77 is bent along line 75 forwardly to constitute a seat portion resting upon the upper edges of the web members 55. The breadth of the panel section 77 is substantially equal to the distance between the intersection of edges 56-57 and the adjacent slot 58, and the web portion 78 of the back panel extends downwardly with its slots 79 interengaging withthe adjacent slots 58 of the web members 55. The wings 4-1 of the side members 21 are bent along their lines of fold 39 until they lie flat upon the body 71 of the back panel, and the tabs 43 are inserted in the slot 32 midway the sides rof the panel 71. The seat wing members 40 are then bent along their lines of fold 38 until they lie at upon the upper faces of the tller members, whereupon the tabs 42 are bent inwardly and are `inserted through the slot 64 of the panel member 63 of the filler member.
When the main blank or frame is folded in the manner described, with the several auxiliary parts properly inserted and interlocked, the furniture element will provide integral seat and back portions rigidly trussed so as to readily withstand weights, stresses and strains. lt will be observedthat the substantially L-shaped web members are securely locked in spaced parallelism within the frame and against any opportunity for movement toward or away from one another. Moreover, these web members are reenforced by the web or leg portions of the filler members which are provided with slots to cooperate in locking engagement with the corresponding slots of the web members. The front end seat brace, when locked in proper seated engagement by the wings or flaps 40, maintain the webs 65 against any tendency to move in an upward direction at the forward end of the chair or seat. The interlocking engagement between the slots 33 of the upstanding body web and the corresponding slots 60 at the lower end of the web members 55 insures rigid connection between these parts at the rear of the chair and at the lower part thereof. The interengagement of the panel element between lines of fold 24-25 and 26 at the upper end of the chair back, together with the in terengagement of the flap 27 with the forward edges of the web members 55 insures rigid connection between the frame itself and the web members 55 at their upper ends. This particular construction and arrangement brings about an interengagement of parts such as to distribute over a number of elements all weights, stresses and strains to which the article of furniture may be subjected.
The front seat brace 52 is of a breadth corresponding to the inner width o-f the chair and the filler members shown in Figs. 5 and 6 are of the same width so that when properly folded and assembled within the frame they will snugly t therein with their several slotted webs interengaged with the spaced upstanding web members 55. Inasmuch as these webs extend throughout the depth of the seat portion, they will all contribute in sustaining the weights to which the seat will be subjected. The interlocking arrangement of the longitudinal and transverse supporting webs brings about a rigid cellular construction capable of offering substantial resistance to pressures from any direction. When the chair is fully assembled with the parts interlocked as here described, it will be understood that cushions of approved construction and design may be applied to the seat and back rest portions, after which lthe entire article of furniture may be enclosed in a suitable slip cover thus producing a pleasing appearance.
Figs. 10 to 19 inclusive of the drawing disclose a blank and various parts to interiit therewith in the production of a chair having arms, the same principle of construction, reenforcement and interlocking engagement of the various parts being present in this further development. The proportions of the back, sides and front, as well as the auxiliary elements to be assembled within the frame have been varied to such extent as to provide arm rests and the necessary reenforcing and supporting elements associated therewith.
In this form of the invention the back panel is indicated at and integrally formed therewith are the side members 91 of identical construction, foldable forwardly and at right angles to the said back panel along the score lines 92. Integrally formed. with one of the side panels 91 is the front section 93 bendable along the score line 94. The free extremity of the front member 93, after being properly folded, may be permanently secured to the opposite side panel by being stapled or otherwise secured to a flap 95 at the corresponding extremity of the opposite` side panel 91. The back panel 90 at its lower end has a bottom section 96 foldable upon the score line 97, and this bottom section carries the upright spacer 98 foldable along the score line 99. This spacer or web corresponds in all respects to the web 32 as shown in Fig. 3 of the drawings except that it is provided wtih three slots 1% disposed in parallelism at the outer edge thereof. The opposite end or top of the back panel is provided with transverse score lines lill, 162 and 1.03 providing panel sections lila, 165 and M6. The free edge of panel 166 is provided with inwardly projecting slots lib? aligned with the slots lili) at the opposite end of the back panel. The panel sections 1M, 10S and 106 correspond in all respects to the blank of Fig. 3 to constitute the top lock and inish for the chair back.
The L-shaped web member shown in Fig. l5 of the drawings correspond in all respects with similar members 55 shown in Fig. 4, except as to size. These webs, three in number, are assembled and interlocked within the chair frame in substantially the same manner heretofore described. A bottom ap 108 as shown in Fig. 10 is integral with one of the side sections 91 and is foldable with respect thereto along the score line 109. The other side panel 91 has a bottom ilap 11G integral therewith and foldable with respect to said side along the score line 111. The front member 93 also carries a bottom panel indicated at 112 foldable upon the front panel along the line 113. When the sides,-bottom flaps and panels are properly folded with respect to one another, the tabs 114 and 115 on bottom flaps 108 and 110 respectively, will be projected through the slot 116 in bottom section 96, while tabs 117 and 118 on the outer edges of bottom flaps 108 and 110 respectively will pass through and interlockingly engage in slot 119 in the bottom panel member carried by the front section 93.
The side panels 91 constitute the sides as well as the arm panels of the chair of this development, and each has an arm rest section 12@ at its upper end foldable along the line of scoring 121. The outer edge of each section carries spaced locking tabs 122. Each side section is also provided with an angularly disposed wing 123, these wings having tabs 124 at their outer ends. The angularity of these wings, determined by the score line 125, corresponds with the angularity of the chair back.
The back supporting section to be assembled with this form of chair is shown in Fig. 14. This section includes the back panel 126, the upper end of which is provided with a ap 127 foldable along the score line 128 in a rearward direction` This flap is provided with spaced parallel slots 129 extending inwardly from its free edge, corresponding in number with and adapted to interlockingly engage with the filler webs 55 within the frame. This back section also has slots 130 near its outer edges spaced inwardly from its rear end and parallel with the recesses or slots 129. Arm ilaps 131 are connected to the back support near the upper portion thereof along the score lines 132. The lower portion of the back support panel is broadened somewhat to provide wings represented generally at 133. These wings are provided with longitudinal lines of scoring 134 and 135 arranged in parallelism so as to provide panels 136-137 to constitute, when properly folded, upstanding Z-shaped webs lying immediately beneath and supporting the arm rest sections 120 of the sides 91. The back supporting section also provides a seat panel 138 defined by score lines 139-140, the said seat panel 138 being disposed at the rear of the seat when in proper assembled position. The lower edge of the back panel is provided with spaced parallel slots 141 to engage and interlock within slots 142 in the L-shaped filler webs 55.
The front panel 93 of the body frame is so cut at its forward end as to provide a forward tlap 146 defined at its sides by slots 142 spaced apart a distance equal to the breadth of the chair seat. This flap projects forwardly from the panel 93 and is to be bent upon score lines 144 and 145 to provide a front seat brace or support 143. The free edge of the flap 146 is provided with inwardly extending spaced parallel slots 147 equal in number with the web members 55 and so positioned as to interengage and interlock with slots 148 of said web members when bent in downward direction. When so folded and interlocked, the free end of Hap 146 will rest upon the chair bottom, the bases of slots 147 will be in engagement with thc bases of said slots 143, and the front seat brace will be disposed in flat supporting engagement with the upper edges of the forward ends of said webs 55. The side portions of the front panel 93 are provided with arm ilaps 149 foldable along score lines 159, equal in breadth with the chair arms.
1n Fig. ll of the drawings a blank iiller section is illustrated, and comprises a substantially rectangular panel 151, the end portions of which comprise supporting webs 152 which are angularly folded on the score lines 153 and 153' in .TZ-shape fashion (see Fig. 19). The webs thus are provided the entire depth of the chair arm and underlie the arm rest sections 120 when the latter are `is shown clearly in Fig. 13.
folded inwardly thereof. The distance between fold lines 153 is equal to the breadth of the chair frame when in set-up position. This filler member is also provided with a central filler section 154 corresponding to the width of the chair seat, bendable upon score lines 155 and 156. The outer end of this filler constitutes a web 157 having slots 158 extending inwardly from its free edge in parallelism and so positioned as to overlie the web members 55 and to interengage with the slots 159 in the upper edges thereof.
1n Fig. l2 there is illustrated another filler section substantially similar in all respects to the filler member of Fig. 1l and with like numerals except for the score lines. It will be observed, however, that panel 151 and web 157 are slightly larger in Fig. l2 in order to compensate for the inclination of the seat portion (see Fig. 18). By folding the filler ends angularly in Z-shaped fashion upon the lines 169-161, supporting webs 160-161 are provided the entire depth of the chair arm and underlie the arm rest sections 12th when the latter are folded inwardly thereof. Each of the filler members shown in Figs. 1l and l2 are provided in their outer edges with spaced inwardly directed slots 162 to interengage with the underlying seat web or brace 55, as will be understood.
Each chair arm is provided with a stabilizing filler niember formed of the same material of which the other components of the chair are constructed, a blank of which This blank is of substantially rectangular form and is provided with pairs of spaced parallel transversely disposed score lines 163 and 164, the spaces between each pair of said lines constituting end members 165 and the portions 164 and 165' constituting side panels. The depth of these filler members corresponds to the height of the chair arm, and when the blank is folded upon the score lines 163-164 a substantially box-like construction is formed. The tab portion 166 formed at one end of the body overlaps the opposite edge 167 of the blank and may be secured thereto by stapling or any other desired means to maintain the filler in substantially box-like form when in properly assembled position. The upper edges of the structure thus formed are provided with arm rest flaps 168 to overlie one another when folded inwardly from their body portions; one of said flaps having outwardly projecting tabs 169 thereon to engage and interlock in recesses or openings 171B in the opposite side member.V The side panel 165' of each arm filler is provided with an angular Walled recess 171 to straddle the underlying web sections of the filler members disclosed in Figs. 10 and 11. The upper end of the arm ller is also provided with slots 172 to receive tabs 122 of the arm rest sections 120. It will be understood that the depth ofthe arm ller corresponds to the depth of the chair arm, and rests at its lower end upon the bottom of the frame within the same. This ller encloses the upstanding wing web members of the ller members heretofore described, and the parts thus intertted and interlocked assure not only a stable chair arm, but also adequate means for maintenance of the supporting webs at all times properly interengaged with one another.
The arm chair is here described as having an arm at each side as is usual in such articles of furniture. However, the invention contemplates an arrangement whereby a pair of separate and distinct chairs may be placed together side to side in such manner as to provide a settee or lounge. In such event, the chair sections would be provided with one arm only upon outer opposite sides of the chair. The two sections thus constructed, placed edge to edge with their armless sides in abutting relationship, provides an adequate settee or sofa equal in breadth to the breadth of two chairs. When the chair frames and their cooperating parts are in proper set-up positions, cushions may be placed upon the seat and back portions thereof, after which the entire body may be covered with a properly fitted cover to present a pleasing appearance and to obscure the chair frame from view. In instances where the settee arrangement is carried out, each chair or unit maybe provided with its individual cover cut and tted properly thereover, or the assembled chair frames may be `provided with a single cover of sufficient size to adequately cover the assembled units so as to present the appearance of a unitary structure. l
