Definitions

  • the invention relates to such pieces of furniture where U-shaped parts form the elastic supports for the reception of the seat-load.
  • Steel tubes or stout metal bands have been chosen as I material for the supports in furniture of this kind according to prior art. These, however, are expensive in the manufacture and unnecessarily heavy.
  • the object of the invention is a support which 10 is easily manufactured and slight of weight, possessing the requisite resisting power, while being elastic to the desired degree at the same time.
  • a further object of the invention consists in thus arranging reinforcing grooves at certain 10 points that there results a preferred elastic yielding in certain directions as compared with other directions.
  • Fig. 1 a perspective view of a chair with the supports according to the invention
  • Fig. 2 a portion of a support in longitudinal section
  • FIG. 3 a modified embodiment of a support in front view
  • Fig. 14 an arrangement of intersecting supports.
  • u comprises two side portions and b whichconsist of a continuous substantially flat strip of a thin material, especially sheet metal.
  • Each side portion has a front leg merging at its upper and lower ends by turns into rearwardly extending arms, the lower arm forming a ground-engaging base.
  • the edges 0 and d of the strip of sheet material are bent upwardly or beaded and a central groove e is pressed into the sheet metal, so that the latter has a corrugated cross-section.
  • the groove e has been cut deeper, as can be seen from Fig. 2, in order to stiffen the support particularly well at this point.
  • the side portions a and b carry the seat 1 and the back i.
  • the seat and the back are elastic like the known steel chairs; the corners f, g and it, however, are safe-guarded against over-straining and against exceeding the limit of elasticity by means of the deeply pressed in groove e.
  • the elasticity 5 of the back i can be large, independent of that of the seat 1, by the groove e being pressed in less deeply at the point h than at the points I or g.
  • Fig. 3 shows a somewhat modified embodiment of the support. Apart from a groove k, extending over the whole length of the support, there are provided shallower and shorter grooves l at the lower corner f. The depth of the grooves decreases with the distance from the corner I and they disappear entirely at point m.
  • a reinforcement is providedapart from the groove eby bending up the edges at point 1:.
  • the beaded edge d causes a further stiffening of the support in lateral direction.
  • the profile of m Fig. 5 shows two grooves e, while the profile of Fig. 6 shows a deep central groove and two less deep parallel adjacent grooves e.
  • Fig. 7 shows diagonally transversal grooves e, while in Fig. 8 the grooves are arranged in a serpentine line.
  • longitudinal grooves are arranged in conjunction with transversal grooves.
  • the support shown in Fig. 10 isprovided, from about the middle of the seat at p to the middle of the lower support base at q, with an inserted reinforcing strip or band 1 which in its shape conforms to the profile of the support 0 and thus makes the support-double-wall'ed in the vertical portion.
  • Fig. 11 only the inserted strip 1- is reinforced bylongitudinal grooves, whereas the post 0', being smooth otherwise, has bent up edges.
  • the side support 0 of Fig. 12 has single inserted reinforcements s at the corners.
  • the back portion t is split up and the outer half has been bent round towards the front in order to form an arm-rest u.
  • Fig. 13 shows a side support w which has like- 4 wise inserted reinforcements and where the upper portion has been slit open longitudinally in the middle so that by bending up the slit parts the arm-rest v, stiffened by grooves, and the equally stiifened seat bearer z are formed.
  • Fig. 14 shows two side supports a: and 11 whose lower base parts are crossed at point 1:.
  • a lateral stability is attained without needing special cross-bars connecting the supports a: and 1/.
  • the crest of the reinforcing corrugations provided in the strip of sheet material substantially extends in longitudinal direction of the strip.
  • the execution of the thin metal supports can be varied in different manners. It is essential that the metal sheets forming the support or the inserted reinforcing sheets are provided with projections which augment the moment or capability of resistance against bending stresses.
