Definitions

  • the invention relates to a bed base of the kind comprising a set of slats or staves, the ends of which are engaged in two opposite sides of the frame, of a shape which follows the perimeter, to determine the bearing surface of the mattress.
  • These frames have seats inside which engage the ends of the staves and these seats are generally created using supports received in a continuous slot which extends along each of these sides.
  • the chassis comprises at least one tie rod engaged in said opposite sides of the chassis to work in traction; it is thus possible to obtain by means of the pulling the effect of reducing the span, so as to prevent the separation of the two opposite sides in question; said tie rod is disposed below and along a moat.
  • the ends of the tie rod can be engaged in the chassis - made in tubular form - by means of notches in the chassis crossed by said ends.
  • the tie can be made with a strip blade and have at its ends notches forming retaining tabs raised in a limited manner with respect to the blade to engage in the edges of a notch crossed by the tie to blade.
  • the ends of the tie may be constituted by flat heads fixed to the same tie and creating lateral elastic teeth for engagement at the ends of the notches made in the chassis.
  • the ends of the tie rod can be formed heads with magnifications and provided with at least one longitudinal slot, in order to allow the assembly approach and the extension of the portions of the heads determined by the slots and which can be resiliently close together.
  • the bed frame and by 3 the staves which are engaged by their ends at opposite sides 1A of the same frame, these sides 1A being the long sides of the rectangle formed by the frame , both in the case of a single bed and generally in the case of the large bed.
  • End staves 3A can also be engaged along the end sides of the chassis contiguous to sides 1A.
  • the frame 1 can be made with a continuous tubular profile with uniform section, or it can be made with welded portions or the like.
  • the sides 1A thereof which engage the ends of the staves 3 have slots 1X which receive the supports 5 constituting the seats 7 for the ends of the staves 3.
  • the staves are inserted by sliding and with a bending thereof.
  • the mounting can also take place as a result of a slight expansion of the central area of the sides 1A of the chassis and by a sliding of the staves progressively towards the end of the above sides, so as to facilitate mounting.
  • the part of the ends of the moat which penetrate into the seats 7 is relatively limited, so as not to increase the curvatures and deformations for mounting too much.
  • the staves tend to bend and cause by reaction on the sides 1A thrusts which do not only present vertical components, but also horizontal components which tend to urge the sides 1A to bend with concavity inwards and convexity outwards; this fact can even dangerously reduce the importance of the grip of the ends of the staves (in particular of the central ones) in the seats created by the supports 5 or in any case in the seats for the ends in question.
  • the tie rod is constituted by a rod or round iron 9 and has at each end a head with magnification 10 and with at least one longitudinal slot 12, capable of dividing the head 10 at least in two portions likely to flex elastically and to approach each other.
  • Each of the heads 10 has a magnification 10A, shared in the portions in which the head is divided by the slot (s) 12.
  • the profile constituting the side 1A of the chassis has - at the position where the tie is to be applied - a notch 14 which, in the case of figs.
  • the head 10, 10A can be asymmetrical in order to adapt to the internal curvature of the chassis.
  • the tie is produced by means of a strip blade 19, on each end of which is engaged a flat head 20 with tooth projections 20A and a slot 22 which allows a certain elasticity of the teeth 20A in the direction of plan of the drawing of fig. 5.
  • the heads 20 can be engaged at the ends of the tie-strip 19 by means of a rivet 21 to allow even, if necessary, a possibility of angular play between the head 20 and the tie 19.
  • a notch 24 is created in which the corresponding flat head 20 can be inserted with a relative elastic approximation of the two teeth 20A, which can be made even directly by profiling the back of these teeth which competes with the ends of the notch 24.
  • the tie rod 29 is once again in the form of a strip-blade and at each end it is notched with slots 31 which form tongues 33 raised from the two opposite parts with respect to the positioning plane of the material in tie rod blade 29; these tabs 33 are profiled to facilitate insertion because of which they can easily penetrate into a notch 35 formed in line with the anchoring zone of the tie rod 29; once crossed the notch 35, the tabs 33 will extend and contrast from the in tieur along the longitudinal edges of the notch 35, thereby engaging the tie which can work in traction.
  • tie rod T (produced in rod or round iron 9 or as an element in the form of a strip-blade 19 or 29) can be placed below a moat 3, so that in any case it is not not visible from above the box spring and also difficult to see from the side and from below.
  • the assembly of the bed thus produced is carried out in successive phases by first bending each moat and its introduction into the two supports 5 relating thereto, then proceeding to slide them as and when the central area (where the assembly is facilitated as a result of a possible deformation even limited of the sides 1A of the chassis) until gradually abutting towards the ends of the chassis, thus completing the assembly of the moats; after completion of the assembly of the staves, the tie is applied which secures the sides 1A of the chassis with respect to a reciprocal distance, the tie or each of the tie rods fulfilling the function of reducing the span of the sides 1A in question of the chassis.
