Definitions

  • the present invention relates to a composable seat structure suitable to be connected to other adjacent seats of equal type, to form a series of supported ranks, for example for meeting halls, or for entertainment premises etc.
  • Numerous seat structures are known formed of a carrying frame, and of a bearing body, generally in plastic material made in one piece, which connects to such a frame. Normally, the union of these forming elements (frame and bearing body implies the carrying out of more or less laborious operations, and in any case, requiring the application of auxiliary fixing means, such as screws, bolts, and the like.
  • One object of the present invention is that of substantially obviating these inconveniences, by making available a seat structure, which, different from what was known up to now, should be such as to permit an assemblege which takes place with extreme rapidity without the employment of connecting means, between frame and bearing body, extraneous to these two elements.
  • Another object of the invention is that said seat structure be devised in a manner as to permit the formation of rigid ranks of seats, without the need to resort in this case either, to mutually connecting means extraneous to the seats themselves.
  • said seat structure be devised in a manner as to permit the formation of rigid ranks of seats, without the need to resort in this case either, to mutually connecting means extraneous to the seats themselves.
  • a composable seat structure of the type formed by a carrying frame and by a bearing body, characterized by the fact that said bearing body is connected to said frame by rapid snap-spring joining means.
  • FIG. 1 shows the seat in which the bearing body is shown partly folded-up and separated from the relative frame
  • FIG. 2 is a section of the structure executed according to the outline IIII of FIG. 3;
  • FIG. 3 is a transverse section of said structure executed according to the outline IIIIII of FIG. 2;
  • FIG. 4 shows, by way of example, how the union of more seats, for the formation of a series of supported ranks of seats, takes place.
  • the seat or chair structure consists of a supporting frame 1 and of a bearing body or seating shell 2.
  • the frame I is for example produced in tubular metal bars and consists substantially of a pair of shoulders 3 and 4 formed from a bar bent in the shape of a U so as to represent a pair of legs, and of a U-shaped holding member or frame portion 5 which is appointed to support the bearing body 2.
  • the member 5 is arranged in a horizontal plane and is connected to the shoulders 3 and 4 through a pair of channel-like connecting members indicated at 6 and 7.
  • Moreover between the shoulders 3 and 4 and the holding member 5 is materialized a pair of supports 8 and 9, provided with parallel vertical lateral walls and with a bottom.
  • the dept of the members 6 and 7 is greater than the width thereof.
  • a slot-like or loop piece 10 characterized for example by a rod 11, bent like a C.
  • the slot or passage 10 is dimensioned in a way to receive the upper cross portion 12 of the shoulder 3 of an adjacent seat, fixing in such a way the stable connection (but easily removable by simple disengagement of a seat with respect to the other) of two adjacent seats.
  • the bearing body 2 is made, for example, by pressing of a suitable plastic material, and is structuralized in one piece forming frontally or a pocket downwardly and rearwardly bent front portion 13, and at its two sides a pair of cavities l4 and 15. In the same bearing body are furthermore made two longitudinal prominences or projections 16 and 17, in the proximity of the bottom of the cavities l4 and 15.
  • the assemblage of the seat occurs in an extremely simple way; the rear part 20 of part 5 of the frame is inserted into the pocket 13, whereupon the bearing body is pressed towards the bottom in a way that its wings or sidewalls 18 and 19 projecting vertically are placed inside the channel-like members 6 and defining an interspace between the ends 21 and 22 of the U-shaped frame portion 5 and the cross portion 12 of the legs 3 and 4.
  • the tubular ends 21 and 22 of the member 5 are inserted inside the cavities l4 and 15, springing over the prominences l6 and 17, fixing in this way the frame to the bearing body.
  • the lateral walls 'of the channel-like connecting members 6 and 7 have for this purpose a thickness smaller than that of the ends 21 and 22, as visible from FIGS.
  • the sidewalls l8 and 19 are slightly spreaded apart when engaged into the channellike connecting members 6 and 7, that is the distance between the projections 16 and 17 is slightly smaller than the distance between the walls of the members 6 and 7 fixed to the ends 21 and 22.
  • every seat canbe jointed to the adjacent seat in the way as stated above forming rigid ranks of seats, of a desired length.
  • a composable chair structure comprising:
  • a supporting frame of metal bars having two parallel U-shaped leg structures spaced apart and transverse connection members for rigidly connecting said leg structures, including a substantially U- shaped frame portion arranged substantially in a horizontal plane and having two end portions for connection to said leg structures,
  • said seating shell having a downwardly and rearwardly bent front portion for engaging the transverse portion of said U-shaped frame portion
  • said U-shaped frame portion is secured to said leg structures by interposition of a respective channellike connecting member defining an interspace between the respective end of said U-shaped frame portion and the cross portion of the corresponding U-shaped leg structure.
  • said channel-like members having lateral vertical walls with a thickness smaller than that of said ends of said U-shaped frame portion and said cross portion of said leg structures, whereby said ends and said cross portion laterally project withing said interspace.
  • said seating shell defines downwardly and rearwardly bent parallel sidewalls, the downwardly bent portions of said sidewalls being provided at least on one side with projections and being insertable within said interspaces, said projections cooperating with said ends of said U-shaped frame portion through resilient deformation so said sidewalls with with respect to one another thereby to clamp said sidewalls within said interspaces, respectively, and locking said seating shell on said supporting frame.
