Definitions

  • This invention relates to chairs and more especially to chairs capable of being disposed in compact relation to each other to form a stack of chairs.
  • the invention particularly relates to chairs of the type in which the seat is mounted at the upper end of a pedestal or column supported by a base.
  • Such chairs in many cases arenot of such design as to be comfortable or to be artistic. It is usually necessary for comfort that both the back of the chair and the seat thereof shall have a contour of the surface to conform to the body. This may be the case even though the chair is provided with cushions of substantial depth for the seat and the back. Moreover, contours other than rectilinear lines in many cases may provide a more artistic chair in consideration of the proportions of the seat, the back, the height of the pedestal and the diameter of the base necessary to meet the conditions of comfort and of stability of the chair. Chairs having such contours ordinarily cannot be stacked readily in close relation one with respect to the other.
  • the chair of the invention utilizes a substantially rigid seat securely mounted upon the upper end of a vertically disposed column or pedestal.
  • This pedestal is securely supported by a base which may rest upon the floor.
  • the base is of such rigid form and construction that it supports the column and the seat mounted thereon so as to afford the requisite stability of the chair, that is, the prevention of tipping forwardly or rearwardly or sidewise, by virtue of its substantial diametral dimensions.
  • the column or pedestal which may be made of any material suitable to provide a rigid column and preferably is made of metal, is of restricted diameter to serve the purposes of the invention while being of sufficient diameter, having regard to the vertical length of the column, to provide resistance to bending or buckling as well as to secure good design appearance.
  • the seat of the chair is provided with a notch open at the forward edge of the seat and extending rearwardly from this edge to an inner end of the notch adjacent the column of the chair.
  • the base of the chair also is provided with a notch or open space disposed at the rearward side of the column and extending from the rearward edge or part of the base forwardly to a forward end of the space adjacent the column.
  • the column is made of such thickness or dimension transverse to the forward and rearward direction of the chair, that is, transverse to the forward and rearward center line thereof, that the column of a chair which is to be nested with a chair standing on the floor may enter the seat notch of the standing chair, the under side of the seat and the back of the chair, if a back is provided, being disposed above the seat and the back of the standing chair.
  • the column of the chair which is being nested with the standing chair may be moved rearwardly in the notch of the seat of the standing chair until the column reaches the inner or rearward end of this notch.
  • the open space or notch provided in t e base being disposed at the rearward side of the column of the chair being nested with the standing chair, permits the movement of the base of the chair being nested rearwardly with respect to the column of the standing chair, this latter column being received into the space of the chair being nested.
  • the columns of the two chairs may be brought into closely adjacent relation to each other and the seats and backs may be disposed in nested rela-' tion to each other.
  • the forward edge of the seat of the chair being nested in the standing chair becomes disposed only a short distance forwardly of the forward edge of the standing chair.
  • the base of the chair being nested is disposed only a short distance forwardly of the base of the standing chair.
  • the chair may not nest in such close relation that the columns of two adjacent chairs are close together.
  • a greater or less numher of chairs may be stacked together in the relation described without risk of the stack tilting from the stable position in which the center of gravity of the stack falls within the base of the lowermost chair.
  • a chair may be lifted somewhat from the floor and its column inserted in and moved to the inner end of the notch of the seat of a chair standing on the floor. Then a third chair may be lifted and its column inserted in the seat notch of the upper chair, these steps being repeated until a stack is built up.
  • the vertical dimension of the base is made somewhat less than the vertical dimension of the seat of the chair.
  • the bases of each of the chairs will be suspended by their columns since each seat structure will rest upon the seat of the chair next below.
  • some particular maximum dimension as, for example, the hub of the base to which the column is secured with respect to the vertical dimension at some particular point on the seat or back or both, may determine the clearance between the bases of two vertically adjacent chairs in the stack.
  • Fig. l is a front view of the chair in elevation
  • Fig. 2 is a plan view of the chair
  • Pig. 3 is a vertical section taken on line 3-3 of Fig. 2;
  • Fig. 4 is a vertical section taken on line 44 of Figs. 1 and 2.
  • Fig. 5 is a top view of a plate supporting the seat at the top of the pedestal;
  • Fig. 6 is a section on line 6-6 of Fig. 5;
  • Fig. 7 is a section on line 7-7 of Fig. 4.
  • the chair of the invention is provided with a seat and back structure or outer shell 1 which is of molded pla'tic, for example, of a polyester resin reinforced with a fiber such as sisal, glass or other suitable fibrous material.
  • the shell 1 is molded as a whole to dimensions to provide the requisite strength and rigidity to support the weight of a person sitting in the chair and to resist the bending or torsional strains which are brought upon the seat and back of the chair in its ordinary use.
  • this outer shell 1 is secured to a pedestal or column at its upper end.
  • the contours of the shell are such that the requirements of design and of comfort may be met, the seat portion of the shell 1 being of a concave form both in its forward and rearward dimension and in its transverse dimension to provide greater comfort than a flat surface. Similarly, the back of the chair may be made concave so as to conform to the back of a seated person.
  • an inner shell '7 is disposed which may be made of paper pulp impregnated with asphalt.
  • This inner shell may be held by adhesive of suitable type to the upper surface of the seat and the forward face of the back portion of the shell 1 and may extend, as shown in Figs. 3 and 4, over the forward edge portion of the seat and the upper edge portion of the back and over .the side edge portions of the seat.
  • edge portions of the two shells are spaced from each other to provide a peripheral recess or groove 13 into which may be received the edge portions of the upholstery fabric 11 which covers the exposed face of the cushion 9 which is secured to the upper surface of the inner shell 7 by a suitable adhesive.
  • the recess 13 is provided by forming a shoulder or rabbet 15 along all of the edge portions of the inner shell 7.
  • the edge portions of the upholstery fabric may be brought down over edge portions of the cushion 9 and lapped upon the shoulder 15 of the inner shell 7 and tacked to the surface of this shoulder.
  • the cushion 9 is made of foam rubber and the adhesive used is one which is capable of bonding the foam rubber to the asphalt impregnated inner shell 7.
  • the assembly of the inner shell 7, the cushion 9 and the upholstery fabric 11 covering the cushion and tacked to the shoulder of the inner shell is first made and this assembly then is adhesively secured to the outer shell 1 after this outer shell has been mounted on the upper end of the pedestal by means about to be described.
  • the contours of the cushion 9 and the thickness thereof at different portions of the area thereof may be such as will provide comfort as well as artistic design.
  • the fabric 11 may be any conventional fabric suitable as upholstery or covering material for the purpose.
  • the outer shell 1 at the bottom surface thereof in the embodiment being described is provided with a shallow recess 17 having a flat surface 19 for engagement with a corresponding flat upper surface of a plate 21 mounted on the upper end of the pedestal or column 23.
  • the column 23 in this embodiment is provided by a tube 25 extending between the lower face 27 of the plate 21 and the upper end 29 of the hub 31 of the base 33.
  • Means further to be described are provided for drawing the lower face 27 of the plate 21 into engagement with the upper end of the tube 25 and the upper surface of the hub 31 into engagement with the lower end of the tube 25 securely to hold the plate and the hub in spaced relation and rigidly connected to the tube 25 as a strut or column.
  • the plate 21 as shown in Figs. 4, 5 and 6 is provided with a plurality of bosses 35 extending upwardly from the upper surface of the plate. These bosses are disposed about tlte axis of the tubular column 23 and in symmetrical relation to the forward and rearward center line of the chair, that is, the horizontal center line in Fig. 5.
  • the outer shell 1, as shown in Fig' 4, is provided with a plurality of recesses 37 extending upwardly from the fiat surface 19 of the shallow recess 17 of the shell 1 for receiving the respective bosses 35.
  • the plate 21 may be made of such material as to provide a rigid structure.
  • the plate may be cast of aluminum or an aluminum alloy so as to provide, without the necessity of machining, planar surfaces at the upper surface of the plate and also to provide smooth bottom and edge surfaces for this plate merging tangentially with the smooth bottom surface of the shell 1.
  • the bosses may be sharply formed and closely to dimension and, as the shell 1 is preferably molded of a plastic, the recesses also may be sharply formed to dimension, so that the bosses 35 may fit snugly into the recesses 37, thereby to secure a tight connection between the shell 1 and the plate 21 to prevent movement of these two members with respect to each other either under the stress of tilting in any direction or of torsion about the axis of the column of the chair.
  • tap bolts 39 engage threads in the bosses 35, suitable washers being disposed beneath the heads of the tap bolts 39 for engagement with the upper surface of the seat portion of the shell 1.
  • an upper stub shaft 41 is provided the .outer diameter of which is such as to fit snugly in the inner diameter of the tube 25.
  • the upper stub shaft 41 may be made of a metal and may be machined to provide an inner space within which a nut 43 may be disposed.
  • the lower end of the stub shaft 41 is provided with a threaded hole through which a bolt or rod 45 extends, the upper end of which is threaded to engage the threads of the stub shaft and to receive the nut 43.
  • the lower end of the bolt 45 extends through an opening in the hub 31 of the base 33, and is provided with a hexagonal head 47.
  • a washer 49 is disposed under the head 47 in a recess 51 formed in the bottom end of the hub 31 of the base.
  • the upper end of the stub shaft 41 is machined or otherwise formed with a flared portion 53 which may be embedded in the metal of the plate 21 as it is cast.
  • the pull of the rod 45 therefore, is resisted by virtue of the secure hold of the flared portion 53 of the stub shaft 41 in the plate 21.
  • the stub shaft 41 thus is secured rigidly to the plate 21 and is snugly fitted to the tubular column 25, so that a rigid connection is provided at the upper end of the column for the mounting of the plate and support of the seat thereon.
  • a lower stub shaft 55 which also may be of metal, is snugly fitted to the inner surface of the tube 25.
  • the stub shaft 55 in the embodiment shown is provided at its lower portion with a plurality of annular grooves 57 separated by annular ridges 59 extending circumferentially about the stub shaft.
  • the base 33 may be made of a suitable material, such as aluminum or aluminum alloy, and the lower end of the stub shaft 55 may be dispo"ed in the mold so that the metal in the hub 31 is cast about the grooves and ridges so as rigidly to hold the stub shaft 55 in the hub 31 with the upper portion thereof extending upwardly into the tube 25.
  • the stub shaft 51 is provided with a longitudinal hole 61 extending therethrough so that the rod 45 may extend therethrough and through the part of the hub 31 adjacent the washer 49 to provide the function of a draw rod as above described.
  • the base 33 provides four generally radially extending arms. Two of these arms 65 extend forwardly of the transverse center line of the column and are disposed in symmetrical relation to the forward and rearward center line of the chair. The other two arms 67 extend rearwardly of the transverse center line of the column and also are disposed in symmetrical relation to the forward and rearward center line of the chair. The arms 65 and 67 extend at angles to this forward and rearward center line.
  • the arms 65 are of such radial length and extend at such an angle relative to the radial length and angle of the arms 67 that the forwardly disposed ends of the arms 65 are at a somewhat greater distance forwardly of the transverse center line of the column than are the rearward y disposed ends of the arms 67 rearwardly of this transverse center line.
  • the angle between arms 65 is somewhat greater than the angle between arms 67. It will be noted further from Fig. 7 that the center lines of the arms 65 and 67 do not proceed precisely radially from the axis of the column but from points which respectively are offset transversely of the forward and rearward center line of the chair.
  • the arms 1 6 65, 67 of the base 33 may be formed through most of their length with an inverted channel shape, having flanges extending downwardly from web portions 71 disposed at the upper side of the respective arms. web portions as well as the flanges are cast in one piece with the hub 31 to provide a rigid central structure rigidly holding the four arms extending at angles to each other and at angles to the forward and rearward center line of the chair. Reinforcing ribs 69 extend transverseiy of the arms 65, 67. A stable base rigidly supporting the column 23 and the seat and its plate 21 mounted thereon thus is secured. Suitable casters or the equivalent of conventional type, which may be in the form of resilient studs or glides 73 provided with metal covers 75 providing smooth lower surfaces, are disposed in sockets provided in bosses formed at the outer ends of the respective arms 65, 67.
  • a notch is formed in the seat portion of the shell 1 of the chair. This notch extends from the forward edge 87 of the shell reawardly to an inner end 89 which is disposed adjacent the column 23.
  • the plate 21 also is provided with a notch 91 which has a contour registering substantially with the contour of the inner portion of the notch 85 of the shell 1.
  • the notch 91 of the plate 21 extends at its inner end substantially to the periphery of the hub 93 of the plate 21 from which a plurality of ribs 95, 97 enxtend radially. Alternate ribs 95 are disposed on the radial center lines of the bosses 35 of the plate 21.
  • ribs 97 are disposed on radial lines 'between the ribs 95. These ribs 95, 97 as shown in Fig. 6 extend from the upper surface 99 of the plate 21 to a web portion 101 which is of conical shape extending outwardly from the lower end of the hub 93.
  • the hub 93 provides a portion of the plate 21 in which the upper flared end 53 of the upper stub shaft 41 is embedded as above described.
  • the width of the notch is substantial with respect to the diameter of the plate. This is necessary in order that tubes 25 of the columns of the chairs being stacked above a particular plate 21 may enter the notch 91 from the forward edge of the plate. The tube 25 of the next chair above must move to the inner end of this notch 91, i.e., the right hand end as it appears in Fig. 5.
  • the number of chairs which may be placed in a single stack depends upon the relation between the seat thickness and the length of the column between seat and base. It is preferred to construct the chairs so that six may be placed in one stack. This limitation of the number of chairs in one stack provides a further improvement over prior stacking chairs where the number in a stack is not limited. With such prior art chairs, it sometimes happens that so many chairs are stacked together that the lower chairs are overloaded, and are thereby bent or broken.
  • the notches 85, 91 are tapered in the direction from the forward edge 87 of the shell to the rearward end portions of the coincident notches, the radius of the inner end of the notch 85 being the same as that of the inner end of the notch 91.
  • the inner shell 7, when made in one piece for the outer shell 1, also is provided with a notch 105 extending from the forward edge of this shell to an inner end which is adjacent the inner end 89 of the notch 85 of the outer shell.
  • the notch 105 also may have a contour or outline substantially coincident with the tapering outline and circular end of the notch 85 of the shell 1.
  • the width of the notch of the inner shell may be somewhat wider along its extent in order to provide for the thickness of the cover-
  • These ing fabric which, as above described, is brought down over the edge of the cushion and over the edge of the inner shell to be secured to the shoulder 15 formed along the edges of the inner shell.
  • the shoulder may be formed also along the edge of the slot for this purpose.
  • the fabric covered cushion is provided with a notch extending from the forward edge thereof and of such width and length as to correspond to the notches 85 and 105 of the outer and inner shells so as to permit entry therein of the column of a chair to be nested or stacked.
  • the inner shell 7, as well as the cushion and its fabric covering may be made in two pieces of such form as to be disposed at either side of and to substantially meet upon the forward and rearward vertical plane through the axis of the column 23 of the chair.
  • each of the pifces is provided with a shoulder along all of the edges thereof corresponding to the shoulder 15, as described in connection with Fig. 4, which forms the recess within which the edge portions of the fabric cover are disposed, this fabric covering being secured to the shoulder as by tacks or other fasteners.
  • the inner shell 7 and the cushion 9 and its covering 11 When the inner shell 7 and the cushion 9 and its covering 11 are thus formed in two pieces, they must be formed with right and left contours and the portions thereof which are adjacent the notch 85 of the shell 1 must be formed with right and left outlines so as approximately to conform to the outline of the notch 85 of the seat portion of the shell 1.
  • the cushion is formed of a resilient material such as foam rubber, the outline of the notch portion of the cushion need not be precisely determined, since the portions of the cushions at either side of the notch 85 will yield when the column 23 of a superposed chair is inserted in the notch.
  • Figs. 2 and 4 are shown in dotted lines the outlines of a chair disposed in stacked relation to and nested above the chair shown in full lines in these figures.
  • the seat and back portions of the shell 1 of the upper of the two chairs engage the upper surface of the fabric covered cushion 9 of the lower supporting chair shown in full lines.
  • the column 23 of the upper chair shown as a dotdash circle in Fig. 2 and shown also vertically in dot-dash lines in Fig. 4, is disposed at the inner or rearward end 89 of the notch 85 of the shell 1 and at the inner or rearward end of the notch 91 of the plate 21 and forwardly of the column 23 of the lower chair. It will be apparent that the column 23 of the upper chair is closely adjacent the column of the lower supporting chair.
  • the two columns are brought closely together without substantial interference of these hub portions of the bases 33. (See Fig. 7.) Having regard to the proximately of the inner end of the notches 85, 91 to the hub 93 of the plate 21, it will be apparent also that the columns 23 of the two chairs are brought into the closely adjacent relation to each other without substantial interference of the parts of the plate which are connected to the column.
  • the forward edge of the upper chair or of its cushion is disposed only slightly forward of the forward edge of the supporting chair or its cushion.
  • the degree of this overhang and the limit of the proximity of the two columns in some cases may be determined by the thickness and contour of the cushions, particularly of the back cushion and the portion of the seat cushion adjacent to the back, but the form and length of the notches 85, 91 and the form and forwardrearward length of the space between the arms 67 of the base provide for as close disposition as possible.
  • a chair adapted to be stacked compactly with other similar chairs which comprises a vertically disposed column, a seat supported on the upper end of said column, and a base connected to the lower end of said column for supporting said column and said seat, said seat having a notch open at the forward edge of the seat and extending rearwardly from said edge to an inner end of said notch adjacent said column, said base providing a rearwardly open space disposed at the rearward side of said column and extending forwardly to a forward end of said space adjacent said column, said column of said chair having a thickness tranverse to the forward and rearward direction such that said column of a given chair may be received in said space of the base of a chair in superposed stacked relation to said given chair concomitantly With the column of said superposed chair being received in said notch of said given chair.
