Description
- 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.
- Rows of seats formed by a horizontal bolster held up by supporting legs, on to which the seat is bolted, are well-known.
- FR-A-2.139.844 describes embodiments of lift-up chairs resting on support legs.
- One of the problems associated with this type of row of seats is the fixing of the supporting legs to the horizontal bolster. Generally, rather complicated means are used, involving numerous screws or even welding which render unattractive the structure of the row.
- Another problem associated with these designs is the system used to fix the seats to the bolster itself. It is generally the case that the seats are made of a single casing or molding, which has to incorporate reinforcements capable of supporting the weight it will be subjected to during its use.
- In an attempt to solve the above problems, a structure has been invented 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 working position.
- The extensions of the semi-clamps which shape the main clamp, as well as the complementary piece, are fitted with pins which can easily be inserted in corresponding holes of the adjoining part, in order to fix them in an adequate working position and guide its movement along the inward-facing part of the tubular leg end.
- 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.
- In order to allow for a better understanding of the above description, some drawings are attached which, though only an example, represent a practical embodiment of the structure and seat which are the basis of this invention as claimed in claims 1 to 7.
- In the afore-mentioned drawings, 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; finally, figure 4 is a front elevation, partially sectioned, which shows one end of the bolster with the side in place.
- It can be seen from the drawings that 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, whosebottom 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 thesemi-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. Thus the semi-clamps are fixed to the bolster 1. - The
semi-clamps 6 and 7 are fitted with extension tracks ortails part 13, which fits next to theextension 12. In this way the shape of the three juxtaposed pieces is consistent with the inner outline of the upper end ofcolumn 2, within which are fitted the threeparts Tailpiece 11 is fitted with arod 14 which fits into acorresponding hole 15 intailpiece 12. This, in its turn, is fitted with a rod 16 which fits into ahole 17 inpart 13. These rods and holes are intended to fix the parts in the work position, as well as holdingparts -
Part 13 is equipped with twoscrews 18 which are screwed into threaded holes. These go freely throughholes 19 intailpiece 12 and come to rest touchingtailpiece 11. The heads of the screws are situated oppositeopenings 20 incolumn 2 which allow access by conventional tools. - When the
screws 18 are tightened,parts column 2 so that thesemi-clamps 6 and 7 are perfectly joined to the upper end of the column. One only has to undo thescrews 18 to be able to dismount the semi-clamps without any difficulty. - The seats consist of two
similar parts screws 25 andbolts 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 anextension 28, which is intended to fit into the end of the bolster, to which it is attached byscrews 29. - A complementary table can be added to the whole, fixed to one of the two ends of the bolster using conventional joins.
- From all the above description it follows that the join of the
legs 2 to the bolster 1 viasemi-clamps 6 and 7, fitted withtailpieces complementary part 13, is extremely simple and at the same time robust. What is more, there are no visible soldered joints or screws, thereby giving the row a much more attractive and clean aspect than many other well-known makes which leave various screws and bolts visible, or even disfiguring soldering marks. - On the other hand, 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 - 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.
- Outside the objective of this invention are the materials used in the construct ion of the seat's components, the shape and dimensions of the same and any other additional accessorial details, as long as they do not affect the basic nature of the seat.
