Definitions

  • the invention relates to. a chair having a seat frame and a separate leg-supporting frame, and more particularly to a chair having a seat frame and disengageable leg-supporting frame.
  • Fig. l is a longitudinal section of a chair showing a preferred embodiment of the invention
  • Fig. 2 is a top plan of onehalf of a partly assembled embodiment of the invention
  • Fig. 3 is an enlarged detail of the upper left-hand portion of Fig. 1,
  • Fig. 4 is an enlarged detail of the upper right-hand portion of Fig. 1.
  • Fig. 1 a chair having a seat frame 1 of bent wood, and a separate legsupporting frame comprising a bottom plate 3 and reinforcing ribs 4. Holes are drilled through plate 3 and ribs 4 for mounting the legs 2. These holes are inclined at an angle corresponding to the inclination which it is desired to give to the legs. The location of the reinforcing ribs 4 also is determined by the position of the legs.
  • leg frame unit may be finished by staining or in any other manner. If it is desired to upholster the seat, this may be done separately at the same time.
  • the front end of reinforcing ribs 4- is provided with a tenon or pinlike projecting member which engages a correspondingly shaped groove in seat frame 1.
  • the width of the groove is made to correspond approximately to the width of the projecting member 7.
  • the bottom plate 3 engages a mating groove 9 in seat frame 1.
  • the reinforcing rib 4- carries a leaf spring 5, one end of which is fastened to the upper side of rib 4 as best seen from Fig. 4.
  • the free end of spring 5 is crimped into a semi-circular bulge and is bent downward.
  • the crimped end of spring 5 resiliently engages a groove or recess 6 of a shape mating the crimped end of the spring 5 when the seat frame and the leg-supporting frame are assembled.
  • the semi-circular shape of the. crimped end. of spring 5 facilitates insertion of the leg-supporting frame into the seat frame, the spring yielding under the pressure exerted by seat frame 1 against the inclined portions of the crimped end.
  • An opening 6a which is narrower than the width of spring 5 is provided in seat frame 1 to give access to the spring 5 so that it may be pushed back towards the reinforcing rib 4 to permit removal of the leg-supporting frame from the seat frame 1.
  • access opening 6a is provided on the underside of seat frame 1 and a corresponding opening 8 is formed in the bottom plate 3.
  • a nail, a pencil, a screwdriver or any other suitable elongated object may be inserted through access opening 6a to push spring 5 out of groove 6 and to permit the leg-supporting frame to be disengaged from the seat frame.
  • the tenon or pin-like projecting members 7 may be replaced by rigid members of many other shapes, and that resilient means. other than a leaf spring 5 may be employed either exclusively or in co operation with one rigid. interlocking element or a plurality thereof. It is furthermore understood that while the present invention has been illustrated by an embodiment having male interlocking members fastened to the leg-supporting frame and engaging mating recesses in the seat frame, some or all of the male interlocking members may be fastened to the seat frame and engage corre sponding recesses in the leg-supporting frame.
  • the chair of the invention is adapted to be stored or shipped with the leg-supporting frame disengaged from the seat frame to which a back and arm rests may be attached in the customary manner. It is apparent that the chair thus disassembled will occupy only approximately one half of the shipping or storage space required by a fully assembled chair of equal dimensions.
  • the chair can be simply assembled by even an unskilled person by first engaging the pins or tenons 7 in their mating recesses in the seat frame and then pressing the leg-supporting frame into place whereby the springs 5 abut against the edge of seat frame 1 and are pushed back against ribs 4 to permit the leg-supporting frame to drop into place whereupon the crimped ends of springs 5 interlock their corresponding recesses or grooves 6.
  • the chair can be disassembled with equal ease by inserting suitable elongated objects behind springs 5 to displace them from recesses 6 whereupon the leg-supporting frame can be lifted out of the seat frame 1 on the side opposite rigid tenons 7 until ribs 4 clear the frame 1 and the tenons or pinlike projecting members 7 can be disengaged by a sliding motion from the corresponding recesses in the seat frame 1.
  • the upholstering process is simplified in important respects. It is apparent that the seat and the back and arm rests which may be attached thereto may be completely upholstered while the leg-supporting frame is detached thus reducing the weight and bulk of material that has to be handled by the upholsterer. It is an additional advantage of the arrange ment of the invention, that the bottom row of upholstery nails may be located inside groove 9 on seat frame 1 where it is completely covered and hidden by bottom plate 3 after final assembly of the chair.
  • An upholstered chair comprising a ring-shaped seat frame which is open at the top and at the bottom, the upper opening serving for spring accommodation, a legsupporting frame removable as a unit, said leg-supporting frame being arranged below the seat frame for attachment thereto and comprising a plate capable of covering the opening at the bottom of said seat frame in assembled position, reinforcing ribs on said plate, said ribs and said plate having registering holes at spaced locations from the sides of said seat frame and being inclined with respect to the vertical plane for mounting the chair legs at an inclination, and a plurality of releasable interlocking elements on said ribs for lateral attachment of said legsupporting frame to the sides of said seat frame, said interlocking elements consisting of projecting members capable of engagement with mating receiving recesses at the inner sides of said seat frame, at least a part of said interlocking elements being resilient for easy removal from said recesses;
  • said interlocking elements comprising a plurality of spaced pins fastened to the one end of said leg supporting frame and a plurality of spaced resilient projecting members fastened to the other end of said supporting frame, the seat frame being formed with mating recesses adapted to engage respectively said pins and said resilient members.
