  • the present invention eliminates this inconvenience in that the seat part consists of two flat portions forming an angle and destined respectively to receive the seat and to secure the 'back of the chair, whereby the free end of the seat part at portion is secured by screwing, riveting, welding or other means to the substantially straight-lined upper portion of the foot part.
  • the slope occasioned by the antagonistically rotating spring members is compensated and the sitter is able to assume a favorable position and to fully enjoy the elasticity of the swinging chair.
  • a most ⁇ favorable slope is obtained by suitably dimensioning the spring steel cross-section or by giving the seat part and the foot part different spring power.
  • the same comfortable position is also eifective by swinging and rocking movement and affords for the sitter a pleasant relaxing sensation.
  • the seat part and the foot part may advantageously be separate spring members.
  • the foot part itself may consist of two parts, one of which is resting on the ground while the other connects said part to the seat part, whereby the connecting member may have a shape comprising angles of curvature like the embodiment shown in FIG. 1, or the same may be S-shaped, the portion adjacent to the foot part and the portion adjacent to the seat part being in this case identically shaped.
  • foot part and the seat part are mechanically independent does not affect the functioning; they are connected to one another by screwing, riveting or welding along the line of Contact existing when the seat is free of load.
  • a foot part frame capable of being forwardly swung out and provided with a leg, may be swingably linked to the seat frame, thus producing a -sort of reclining chair, the ⁇ back of the chair being suitably bent, enabling the user to lie on his back.
  • FIG. 1 is a schematical view of the basic structure of the chair according to the invention.
  • FIG. 2 shows an advantageous embodiment of the invention, the chair being supposed to be free of load
  • FIG. 3 shows the same embodiment, the chair being supposed to be occupied
  • FIG. 4 shows a detail of the embodiment illustrated in FIGS. 2 and 3.
  • a foot part 1, 5 rests on the ground with its points of support 2, 3. Said foot part is bent from the ground between the points of support, the greatest distance 10 from the ground being situated in the middle between the points of support. The upward bend increases the spring action of foot part 1, 5.
  • Said foot part 1, 5 has the shape of a V lying down, whereby according to the invention the curvature is in decrease from the reversing point 4 and goes over into an entirely straight zone 6 on which is fixed the seat part 7, 8 by means of screwing 9.
  • the seat part 7, 8 is made of ilat bar spring steel.
  • the desired form of chair determines the angle formed by the at portion 7 destined to receive the seat and the flat portion 8 destined to secure the back of the chair.
  • the frame 7, 8 consists of two separate flat springs 7 and 8 adjustable at every desired angle by means of a toothed segment 12.
  • a padding 21-not shown in the first embodiment- is disposed on a foot part frame 15.
  • Latter is capable of being forwardly swung about the axle 18 in a shplate 16 rigidly connected to the seat frame 13 beneath. Said foot part frame 15 is swung out and is supported by a leg 19 linked to the foot part frame 15.
  • the seat frame 13 slidably rests with a roller 14 on the flat portion 7 to which its rear portion is linked over a hinge 11.
  • the seat frame 13 ⁇ easily adapts to any position of the spring members and allows within certain limits a to-and-fro sliding movement in horizontal direction.
  • the dotted lines 24 in FIG. 3 indicate the finished piece of furniture comprising side parts; the dash-lines 25 indicate the range of displacement of the back-rest.
  • the swinging chair according lto the invention enables to-and-fro rocking as well as vertical swinging as indicated by the arrows I and 1I in FIG. 3. Latter movement specially when the user is seated on or near the fore edge of the seat.
  • a swinging :chair comprising a seat part, a foot part and a back-rest secured to said seat part, said foot part comprising a spring -metal portion having a shape resembling a laid down V forwardly open, said seat part comprising a flat spring portion superposing the upper surface of said spring metal portion, the forward end of said dat spring portion being xed to the top front section of said spring metal portion in a springy connection with a rearwardly opening acute angle between said portions, said seat part comprising a seat frame whose fore edge rests with a roller on the upper surface of said flat spring portion, the rear end of said seat frame being linked over a hinge carried by said ilat spring portion.
  • Swinging chair as defined in claim 1, comprising a foot frame resting on the seat frame with which it is swingably connected.
  • Swinging chair as dened in claim 2, comprising an upright shplate rigidly connected to the seat frame, the foot frame being swingable about an axle of said lishplate, further comprising a leg swingably mounted at the opposite side of the foot frame, said leg being a resting member on the ground when swung out.
