Definitions

  • This invention relates generally to economical, easily transported and rapidly set up chairs suitable for large gatherings such as sporting events, lawn parties or parades; and i&ore particularly to a collapsible, disposable chair of corrugated fiberboard or like generally planar recyclable material.
  • our invention is a disposable chair, though it may be reused many times if desired. In only a few seconds — as few as two or three seconds — our invention, if already set up for use as a chair, can be folded flat for storage and shipment; or if in that latter condition can be unfolded and configured for use.
  • the chair includes four contiguous and rectangular panels.
  • the panels should be of material that is of generally planar character. By that we mean that the material is extended in only two dimensions and very thin in a third dimension. Thus it may alternatively be called "sheet material.”
  • the material should, however, be sufficiently stiff and strong in the aggregate, when configured for use, to support a person.
  • the four rectangular panels define generally vertical edges of equal length. That length is the overall height of the chair.
  • One pair of the four rectangular panels is mutually of equal width. That is the width of the chair when in use.
  • One panel of this particular pair forms the back of the chair.
  • the other panel of this pair has portions that respectively form the front and seat of the chair.
  • Another pair of the four rectangular panels is mutually of equal width, which width is the front-to-back depth of the chair when it is in use.
  • Each panel of this other pair forms one of the sides of the chair.
  • These four rectangular panels are joined along the entire lengths of their equal-length edges.
  • the side panels alternate with the front and back panels, to form a continuous four-panel row.
  • the opposite ends of this four-panel row in turn, can be joined to form a continuous upstanding tube of rectangular plan.
  • a fifth rectangular panel is disposed erect within the tube, and defines two vertical edges and a horizontal upper edge. This fifth panel is joined along its two vertical edges to either of the two pairs of rectangular panels mentioned above; it is parallel, and nearly equal in width, to the remaining pair of rectangular panels.
  • the fifth panel is of generally planar material — but sufficiently stiff and strong to significantly aid in supporting, and in distributing to the other four panels for support thereby, a person's weight.
  • the seat-forming p-rtion of the panel that forms the front and seat of the chair is folded downwardly and inwardly, with respect to the tube, against the back of the chair. In that position it is supported by the horizontal upper edge of the fifth panel.
  • Each side panel is doubled over and inward, with respect to the tube. This folding-over of each side panel is along a line extending generally from the top rear corner of the chair downward and forward to intersect the transverse fold in the panel that forms the front and seat.
  • the seat panel is scored — or otherwise adapted for folding — along additional intermediate angled lines.
  • One such preferred feature is a beverage or implement holder, formed in the corrugated material of the chair by die-cutting at the same time all other parts of the chair are formed.
  • the holder is simply pulled out into position, and greatly alleviates the previously mentioned difficul- ties of some users in handling beverages or other articles while seated in a corrugated-product chair, as well as avoiding the necessity of placing beverages or the like on dirty, uneven or hot surfaces.
  • Another preferred feature is that the fifth panel satisfy certain conditions.
  • the height of the fifth panel generally defines the height of the chair seat, and that that height generally equals the difference between the overall height of the chair and the front-to-back depth of the chair.
  • This condition upon the height of the fifth panel will be explained in the detailed description that follows.
  • Yet another preferred feature is an intermediate, generally planar vertical strip interconnecting one of the two vertical edges of the fifth panel with a vertical edge of one of the other four panels.
  • This strip stands parallel to and in generally planar contact with some one of the other four panels, and is of a width that is very generally half the width or depth of the chair.
  • the main function of this intermediate strip is to interconnect the fifth panel with a corner edge of the continuous row of panels that forms the tube.
  • T * e inter- connection makes it possible for the fifth panel to be part of the same unitary blank that forms the rectangular tube.
  • Another preferred feature is a generally vertical tab, unitary with the other of the two vertical edges of the fifth panel. This vertical tab secures that "other" vertical edge to a rectangular panel which is opposite the intermediate strip. In this way the fifth panel can be positioned parallel to either the front and back panels, or the side panels, of the rectangular-plan tube.
  • the fold itself functions to very greatly stiffen the fifth panel; hence the extension panel may instead be called a "stiffening-angle tab.”
  • the fold line may be regarded as the previously mentioned “horizontal upper edge” of the fifth panel, since the seat is supported on this fold line.
  • All of the five panels, and the intermediate strip and the vertical tab as well, can thus be formed of a single unitary blank.
  • One of the four first-mentioned rectangular panel ' s is at one end of the blank, and the tab is at the other end ⁇ i ' he blank.
  • the panel that is at one end of the blank is secured to the intermediate strip, as a convenient arrangement for completing the continuity of the tube.
  • the refinements which provide these advantages include (1) a lengthening of the stiffening-angle tab itself so that when folded down it contacts the rear panel of the chair, (2) addition of a notch at the extreme edge of the panel, and (3) adding to the panel a through-cut, parallel to but offset slightly below the folding score.
  • the lengthening of the stiffening tab increases a user's leverage in folding down the tab. A user can insert fingers into the notch, to grasp and raise both the seat panel and the tab at once for disassembly.
  • the through-cut converts a shallow part of the fifth panel from being part of the vertical-support column to being part of the horizontal tab.
  • Another method within the scope of our invention is the converse method for placing the chair in use. It includes these steps:
  • our invention provides a very light but strong, reinforced disposable (or reusable) chair that may be made of corrugated fiberboard very inexpensively, with negligible waste. It requires extremely little preliminary assembly — and even that can all be performed by very simple machine operations.
  • the chair takes a very minimum of space for shipment and storage, and only a very few seconds of unskilled labor for setup or knockdown. It has not even one assembly tab to slow either task — or to wear or be damaged. It is improved over our earlier chair in that it is more comfortable, more readily set up and refolded by people working without personal demonstration of the tehnique, and more accommodating of elderly or other people who lack coordination needed for managing drinks or other articles while seated in the chair.

  • Fig. 12 is an enlarged perspective view of the beverage holder deployed for use with a beverage container or the like.
  • Fig. 12a is a like view of holder in use.
  • a preferred form of our invention when set up for use is a chair with a generally horizontal rectangular seat panel 24 (including three subpanels or portions 24', 26 and 29), and generally vertical rectangular front and rear panels 3 and 7-25-31-32 respectively.
  • the chair also has generally vertical trapezoidal left and right side panels 1 and 5 respectively. (All references to lateral direction in this despription are as viewed from in front of the chair. ) These are the four rectangular panels first-mentioned in the brief description above.
  • the upper portions of the sides of the chair (the portions above the seat 24) are double walled, with inner side panels 30 on the left side and 27 on the right.
  • inner side panels 30 and 27 ar continuous with the outer side panels 5 and 1 respectively, being folded over at double folds 19, and they suspend the seat 24.
  • the seat also rests upon an internal cross-panel 11 (the "fifth panel” mentioned earlier), which is stabilized by a right-angle fold 15 at the base of part of its extension panel or stiffening-angle tab 14.
  • the seat is triply supported — in compression by the front panel 3 and internal panel 11, and in tension by the inner side panels 27, 30.
  • the front panel 3 typically bears the next largest fraction of the weight.
  • the tension effect of the inner side panels 27, 30 in suspending the seat 24 normally comes into play only if the occupant enters the seat in such a way as to slightly damage the internal cross-panel 11 or to slightly disrupt the stiffening effect provided by the right-angle fold 15 — or if the occupant sits in the seat in a skewed fashion that tends to slightly lift the seat away from the internal cross-panel 11.
  • the chair has a handhole 17 for convenience in carrying. It also has a hand-access slot 21 for use in preparing the chair for shipment, storage, or disposal as will be explained shortly.
  • the upper portions 25-31-32 of the erected chair are generally coplanar with the lower portion 7, and the same is true of these portions even when the chair is folded flat for shipment, storage or disposal. Nevertheless, the upper portions 25-31-32 are separated from the lower portion 7 by a horizontal fold line 16; and the upper central portion 25 is separated from the upper side portions 31 and 32 by diagonal fold lines 18. Similarly the seat panel 24 central portion 24' is separated from its corresponding generally coplanar side portions 26 and 29 by intermediate diagonal fold lines 20. - 12 -
  • the preferred form of our invention can also assume the flattened or "closed” configuration of Fig. 4. In this condition it is extremely compact. More specifically, the overall thickness is only at maximum three layers of the fiberboard or other material, while the overall "height" (that is, the lengths of the glued edges 8, 33) is only equal to the height of the back panel of the erect chair. Furthermore, the width of the flattened chair is the sum of the widths of only two panels — e. g.. front panel 3 and side panel 1, as shown. In Fig.
  • Figs. 5 and 6 represent two configurations of the chair. These configurations are intermediate between the flattened or "closed” condition of Fig. 4 and the opened condition of Figs. 1 through 3. In the first intermediate configuration, the flattened or "closed” chair of Fig. 4 is still erect, but now partially unfolded, or "folded open,” into a parallelogram- shaped tube. To obtain this condition from that of Fig.
  • Fig. 5 also illustrates attachment of this panel 11 to the left side panel 5 by a glue tab 13 and to the right side panel by intermediate panel 9.
  • the top edge of the center portion 24' of the seat panel 24 is pulled outward, while its top left and right corners are pushed inward — thus passing through the "lost motion" phase.
  • the side portions 26, 29 of the seat panel are folded back along the diagonal scores 20.
  • the entire seat panel 24 is pushed backward, inward and downward to approach the position rep sented in Fig. 1.
  • the seat panel 24 is reflattened at its diagonal scores 20; and the original outer-corner scores 2 and 4 (above the seat-forming score 22) are reversed, becoming inner corners, and are tucked into position against the inner side walls of the chair.
  • the height of the seat panel 24 above any supporting surface of course equals the difference between the overall height of the chair and the length of the seat panel 24 — i. e.. its vertical length before it is pushed back. Since the seat panel 24 spans the front-to-back depth of the chair, its length substantially equals the common widths of the side panels 1 and 5. (The angle of the double-fold lines 19 to the horizontal is thus forty-five degrees).
  • the height of the seat panel above any support surface is therefore, as previously mentioned, generally equal to the difference between the overall height of the chair and the front-to-back- depth of the chair. It will be appreciated that if the seat panel 24 were rigidly planar, it would not be physically possible to move the seat panel 24 from its Fig. 7 position to its Fig. 1 position.
  • the seat panel 24 is divided into central portion 24' and side portions 26 and 29. These are separated by respective auxiliary or intermediate fold lines 20, which allow the upper side-panel portions 27 and 30 and the seat-panel side portions 26 and 29 to buckle inward as indicated in Fig. 7.
  • the rear panel is also provided with diagonal fold lines 18 and a horizontal fold line 16.
  • Fig. 4 starting point of the final-assembly process shown in Figs. 4 through 7 is a structure that has already been preliminarily assembled.
  • the preliminary steps include partial folding, securing of the tab 13 to the inside of the lower left-hand side panel 5, and securing of the inside of the right-hand side panel 1 to the intermediate panel 9.
  • Figs. 10 and 11 show how our entire chair can be folded up from a single blank of sheet material. They thus implicitly show also how the flattened form of Fig. 4 of our invention can be prepared from such a blank.
  • the relationship between Figs. 10 and 11 may be con- ceptualized as follows. Starting with Fig. 11, in essence the rear panel 7-25-31-32 remains in position while the other panels fold "forward" or "upward” out of the plane of Fig.
  • the intermediate strip 9, the "fifth panel” 11 with its extension 14, and the glue tab (or more generally “securing tab") 13 all fold forward in two right angles at the right-rear-corner vertical fold line 8 and the right-internal-corner vertical fold line 10.
  • the "fifth panel” 11 and extension 14 are parallel to and directly forward of the back panel 7-25-31-32.
  • the glue tab 13 folds either in the same or (as illustrated) the opposite sense in another right angle at the left-internal-corner vertical fold line 12.
  • the glue tab 13 and intermediate strip 9 are mutually parallel, but at right angles to the rear panel 7 and "fifth panel" 11.
  • the side panels 1 and 5 and the front-and-seat panel 3-24 all fold forward in three right angles along the left-rear-corner vertical fold line 6 and the two front-corner vertical fold lines 2 and 4. Consequently, (1) the inside of the left side panel 5 meets the glue tab 13 to form a parallel joint, (2) the front panel is directly in front of and parallel with both the back panel 7-25-31-32 and the "fifth panel" 11, and (3) the inside of the right side panel 1 meets the intermediate strip 9 to form another parallel joint. Specifically, the far left-hand edge 33 of the blank as shown in Fig. 8 meets the right-rear corner fold 8, as shown in Figs. 4 through 6.
  • Fig. 11 shows the blank from the "inside”.
  • glue is applied to the tab 13 on the inside of the sheet, and then the blank is folded over along the right edge 8 of the rear panel 7-16-17- 25-31-32 to glue the tab 13 to the left side panel 5.
  • glue is applied to the right side panel 1 in a stripe along its rear edge 33.
  • the blank is folded along the corner 4 between the left-side panel 5 and the front-and-seat panel 3-24, to secure the right side panel 1 to the outside of the intermediate strip 9.
  • the blank shown in Fig. 11 made from double-wall corrugated fiberboard with a Mullen test of 19.3 to 24.6 kg/cm 2 (275 to 350 pounds per square inch) bursting strength or liner-weight combination of 538 to 616 g/m 2 (110 to 126 pounds per thousand square feet).
  • B-type medium fluting toward the outside of the glued tube, and C-type fluting inside. Dimensions will vary with the sizes of people to be accommodated. In mass production for use by the general population, we prefer the following:
  • the width of the intermediate strip 9 and of the front-to-back length (when horizontal) of the extension 14 can be adjusted between rather liberal limits.
  • the "fifth panel" 11 should be midway between the front and rear panels 3 and 7. We strongly prefer to select these two dimensions so that the "fifth panel” 11 is somewhat closer to the rear panel 7. In typical or normal use the user's torso and hence the greater fraction of applied weight are placed behind the front-to-back central plane of the chair. We thus prefer to make the intermediate strip 9 approximately 13.3 centimeters. We have recently refined the stiffening-angle tab to optimize a tradeoff between structural stabilization and user comfort.
  • Part of our invention lies in our recognizing that in this type of chair too much stability degrades the comfort of users — especially in protracted use.
  • the through-cut 15c advantageously can be formed with two short end segments 15e, relatively sharply angled to the fold line 15, that substantially connect the through-cut 15c to the fold line 15.
  • the through-cut 15c if preferred can be instead tapered back to the fold line 15.
  • the configuration of the cut which we prefer is a hybrid of these two possibilities — a five-segment path.
  • a central segment 15o parallels the fold line 15, two very short end segments 15e are perpendicular to the fold line 15, and two intermediate very shallowly tapered segments 15t connect the short e segments 15e with the central segment 15o.
  • connection of the through-cut 15c to the fold 15 be completed by die-cutting; reliance can instead be placed on a very slight amount of tearing or buckling to complete this connection.
  • the offset through-cut creates a short forward horizontal extension 15f of the horizontal panel 14, and a shallow declivity or cavity 15d in the top of the associated vertical panel 11.
  • the user's weight is supported in part on the combined horizontal surface 15f-14 of the fifth panel. This combined horizontal surface spans the declivity or cavity 15d.
  • the user's weight deforms the seat panel 24 and the combined horizontal surface 15f-14.
  • the user's weight presses the combined horizontal surface 15f-14 partly or completely (depending upon the user's weight and dimensions) downward into the declivity 15d.
  • the chair by this deformation tends to conform to the user's shape.
  • the combined horizontal surface tends not to "bottom out” in the declivity 15d and thus, instead retains some springiness. This configuration thus promotes comfort for both users.
  • the previously mentioned five-segment cut configuration causes the declivity in the vertical portion 11 of the fifth panel to be gently tapered for comfortable conformance to the body of a middle-size, middle-weight user, but still provides a small vertical drop at each end of the declivity to create a springy "span" effect for smaller, lighter users.
  • the front-to-back length (when horizontal) of the extension 14 should be approximately 13 to 13.3 centimeters to match the intermediate strip 9.
  • the finger notch 21 in the back panel can be approximately 4.4 centimeters wide, and the corresponding notch 14n in the stiffening-angle tab 14 can be approximately 5.7 centimeters wide. Both notches can be approximately 1.9 centimeters deep. It is possible to adjust the chair design for users' size and weight. Both the length of the offset cut 15c and the maximum offset distance (the distance from the offset segment 15o of the cut and the extension of the fold line 15) may be progressively decreased for relatively larger, heavier people. Such users seem to slightly deform the structure for themselves, without the need for a built-in stiffening- moderation (or "weakening") feature. For such people it is accordingly preferable to trade away some comfort and gain greater stability. Fig.
  • die-cuts 43, 44 form inner and outer cut edges of a separated loop 41, which folds upward and outward along score lines 42, as indicated by the broad arrow 48 — so that the loop 41 stands out at generally a right angle, i. e.. in a generally horizontal orientation, from the surface of the vertical side (or other) panel 5.
  • the inner and outer cuts 43, 44 also form respective inner and outer cut edges 47, 49 of a "U"-shaped aperture 46. At the bottom of his aperture 46, the outer cut edge 49 forms a platform for supporting a beverage container or the like.
  • a stiff flap or tab 45 is left behind when the loop 41 is folded upward and outward, defined by the inner edges 47 of the aperture 46.
  • a score 42' across the top of this flap 45 facilitates bending of the flap 45 inward by h.. pressure, or by pressure from a beverage container or the like. This inward bending makes it easier for a person to grasp the loop 41 to pull it out into position, and also makes a more definite space available for resting of a container on the "platform" 49. Yet the flap 45 continues to resiliently exert some counterpressure outward on the container to help hold it against the inner cut edge 43 of the loop 41.
  • Fig. 12a shows how a beverage container 50 or the like fits into the holder 40. The loop 41 encircles the container 50, and the container 50 presses the flap 45 inward.
  • the inward displacement of the flap 45 caused by manual pressure when the holder 40 is first put into use, or by pressure from a container 50, or by both — allows the bottom portion of the container 50 to rest upon the platform formed by the outer edge 49 of the aperture 46.
  • the flap 45 meanwhile presses outward against the beverage container 50 or the like — increasing the frictional force between the container 50 and the loop 41, to keep the container from slipping out of the loop.
  • the friction between the can and the loop is high enough to hold the can in place even without reliance on the platform 47.
