Definitions

  • the present invention concerns a structure for the formation of rows of seats and the seat itself, a design which is both simple and robust.
  • FR-A-2.139.844 describes embodiments of lift-up chairs resting on support legs.
  • a structure which has a rigid horizontal bolster, held up by supporting legs, along which the seats and an optional complementary table are fixed, the legs are attached to the bolster by track clamps made up of two pieces or semi-clamps which are self complementing, said track clamps in their complimentary position define an inner surface to which the outer surface of the bolster is attached to these clamps having means to alter their grip on the bolster, being fitted with extension tracks in the form of juxtaposed tailpieces, characterised in that these clamps are complemented by a third piece juxtaposed with the extension of one at least of the semi-clamps described above, said whole structure forming a group whose outer surface corresponds to the inner surface of the upper end of the leg, which is of a tubular shape, into which the above described group is inserted, said described group being equipped with means to guide and centre it into a working position and also with drive-screws to adjust its extension against the inward-facing part of the tubular leg end, thereby fixing it in its
  • the complementary piece of the semi-clamp extensions is fitted with screws mounted in threaded holes, these screws moving freely over holes in the adjoining extension of one of the semi-clamps and resting against the other extension, in such a way that the heads of the screws are situated opposite an opening in the end of the leg so that to allow access with a conventional screwdriver.
  • One of the semi-clamps is equipped with a threaded lug which runs along the length of its inward-facing side and crosses a hole made in the bolster, the other semi-clamp having a hole through which a screw is inserted which crosses the bolster and threads into the afore-mentioned lug, thus securing the semi-clamps to the bolster.
  • the bolster is of a tubular shape, and in at least one of its ends there is an end-piece attached, which is then situated at the side of the adjoining seat, and also fitted with a flexed extension, which fits into the end of the bolster, and is attached by sets of screws and bolts.
  • Every seat comprises two similar parts that constitute the actual seat, and the back, both parts being equipped with back sides shaped to fit the front and upper sides, respectively, of the bolster, onto which they are placed and fixed by screws and bolts.
  • the bolster has a rectangular cross section and is fixed in a transversely inclined position.
  • the inclined back rests of the seats are positioned and fixed onto the bigger sides of the bolster.
  • figure 1 is a longitudinal section of the mounted structure, on a plane which passes through one of the legs supporting the bolster;
  • figure 2 is a cross section of the structure on a plane parallel to the previous figure, showing the join of a seat to its corresponding back in the bolster;
  • figure 3 is a cross section of the upper end of one of the legs, showing the arrangement of the semi-clamp extensions;
  • figure 4 is a front elevation, partially sectioned, which shows one end of the bolster with the side in place.
  • the structure for the construction of rows of seats is made up of a tubular bolster 1, rectangular in cross section, supported by tubular legs 2, whose bottom end 3 is joined by screws 4 to a base 5.
  • the join of the legs 2 to the bolster 1 is achieved through two complementary semi-clamps, 6 and 7. They form a "C" shape which complements the outer outline of tile bolster.
  • Semi-clamp 6 has a protruding lug 8 on its inner side, with a threaded hole, while the semi-clamp 7 is fitted with a hole 9 .
  • a screw 10 runs through this hole and then the bolster 1 and screws into the threaded lug 8.
  • the semi-clamps are fixed to the bolster 1.
  • the semi-clamps 6 and 7 are fitted with extension tracks or tails 11 and 12, which complement each other. When they are placed in the work position they are completed by part 13, which fits next to the extension 12. In this way the shape of the three juxtaposed pieces is consistent with the inner outline of the upper end of column 2, within which are fitted the three parts 11, 12 and 13.
  • Tailpiece 11 is fitted with a rod 14 which fits into a corresponding hole 15 in tailpiece 12.
  • This, in its turn, is fitted with a rod 16 which fits into a hole 17 in part 13.
  • Part 13 is equipped with two screws 18 which are screwed into threaded holes. These go freely through holes 19 in tailpiece 12 and come to rest touching tailpiece 11. The heads of the screws are situated opposite openings 20 in column 2 which allow access by conventional tools.
  • the seats consist of two similar parts 21 and 22, like small perforated plate buckets, which constitute the actual seat and its back. These parts have an inclining rear side so that they complement the main surfaces, both front and back, of the bolster 1, against which they are positioned and attached by means of screws 25 and bolts 26 or another similar anchoring device.
  • the sides or end-pieces 27 are housed in one of the two ends of the bolster 1. These are equipped with an extension 28, which is intended to fit into the end of the bolster, to which it is attached by screws 29.
  • a complementary table can be added to the whole, fixed to one of the two ends of the bolster using conventional joins.
  • the configuration of the seats is a very simple one, as is their join to the bolster. It is, nevertheless, very strong and offers a wide contact surface area to the user with its back sides 23 and 24.
  • the seat and the back are made out of a single piece; a perforated sheet and in the shape of a shallow bucket. They are self-supporting; they need no additional reinforcement, nor do they need any special mechanisms to join them to the bolster, as the sides of the parts give them sufficient rigidity.
