Definitions

  • the present invention relates to a bed of the type known as slats, that is to say in which the bed base consists of slats arranged parallel to each other.
  • slatted bed bases generally composed of flexible slats resting at each of their ends on a rigid frame thanks to a nozzle.
  • the patent FR 94.05584 describes a bed base with rigid slats connected at each of their ends to a rigid frame by means of a bent end piece comprising at its lower part two half-portions of toothed wheels which mesh with one another, said said toothed wheels each comprising an orifice in which a rigid rod is engaged.
  • Said rigid rods comprise at each of their ends an elastic return spring making it possible to return the rods to their initial position.
  • the advantage of such a device is to allow flexibility of the bed base over its entire width without deformation regardless of where the load is located, the rigid rods connecting the two end pieces cause their simultaneous deformation of the same importance.
  • the present invention aims to overcome these various drawbacks while retaining a flexibility distributed over the entire width of the bed regardless of where the load is applied.
  • the present invention relates to a bed base consisting of parallel transverse slats connected at each of their ends to a rigid frame, characterized in that it comprises two sets of slats: a first set of rigid upper slats and a second set of slats flexible lower, and in that said rigid upper and lower flexible slats are connected by at least one return spacer which ensures the transmission of forces due to the load of the rigid upper slats to the flexible lower slats.
  • FIG. 1 represents a bed base 1 made up of at least two rigid upper slats 2 and at least one flexible lower slat 3, the upper and lower slats being connected by a return spacer 4 which transmits the force.
  • the upper slats are arranged two by two and spaced regularly and perpendicularly to the longitudinal central axis 5; they comprise at each of their ends a deformable support 6 provided with means ensuring its deformation and ending at its lower part by two toothed half-wheels 7 which mesh with one another.
  • Each toothed half-wheel 7 comprises in its center a rod 8 preferably of square section which fits into the end of a rigid bar 9 preferably also of square section and which is integral in rotation with the half-wheel tooth 7, the so-called rigid rod connecting the deformable supports 6 to each other.
  • the deformable supports 6 are connected to the flexible lower slats 3 by means of an end piece 10.
  • the bed base is thus made up of groups comprising two upper slats and a lower slat.
  • the deformable support 6 comprises at least two hollow parts 11 intended to receive two rigid upper slats 2. It is preferably made of semi-rigid plastic material with a strong elastic memory. Said deformable support 6 is composed of two upper branches 12, symmetrical with respect to the central axis of the endpiece, which are fitted into two lower branches 13 by means of a hinge 14 allowing the support 6 to be bent to an extreme position without causing wear on the fold.
  • the upper 12 and lower 13 branches form an angle of 90 ° between them when the deformable support 6 is at rest.
  • the lower branches 13 end in two toothed half-wheels 7 each comprising on their internal face a rod 8 preferably of square section which fits into a rigid bar 9 preferably also of square section.
  • Said rigid bars 9 interconnect the deformable supports 6 and therefore the rigid upper slats 2; they are integral in rotation with said deformable supports 6 which implies that when a deformation is applied to one side of the bed base, the deformation drives the gear of the two toothed half-wheels 7 which transmit the movement from the side opposite the bed base via rigid bars 9.
  • Said toothed half-wheels 7 also each comprise at their center on their external face in the extension of the rods 8 a stud 15 preferably of round section intended to fit into an end piece 10 making the connection between the flexible lower batten 3 and the deformable support 6.
  • said end piece 10 of flat rectangular shape comprises on its internal face two hollow cylinders 17 intended to receive the two studs 15 of the deformable support 6 and a flared U-shaped projection 18 on which install the end of the lower batten 3.
  • the rigid upper 2 and flexible lower slats 3 are connected by at least one return spacer 4 which has a general T shape.
  • This return spacer 4 is preferably made of semi-rigid plastic.
  • the horizontal upper bar of the return spacer 4 bears against the upper slats of the group so as to transmit to the lower slat any force undergone by these upper slats.
  • this support is produced by forming the upper part of the T so that it includes, for each upper slat of the group, an orifice in which this slat can be positioned in a sliding manner.
  • the return spacers 4 comprise in the example shown two holes 21 intended to enclose the upper slats 2 while letting them slide. Said return spacer is extended by a flat section arranged symmetrically and perpendicularly to the two orifices 21 and comprising on its underside a pin 19 (see fig. 5) intended to be embedded in a hole 20 arranged for this purpose on the lower batten 3.
  • the upper 2 and lower 3 slats of each group are connected by at least two return struts 4 arranged symmetrically with respect to the longitudinal central axis 5 of the bed base 1.
  • the spacing of said spacers is symmetrically variable; for this purpose, a plurality of holes 20 have been placed on the lower batten 3. Said holes are evenly spaced with respect to the longitudinal central axis 5, so that it is possible to move the spacers 4 by sliding them on the upper slats 2 between the rigid bars 9, then to fix them to the 'desired location on the lower batten 3 through the pin 19 placed on the underside of said spacer.
  • This combination not only allows the deformable support 6 to return to its initial position when the load is removed but also provides general elasticity and flexibility of the box spring not only longitudinally but also transversely, regardless of where the weight applied to the bed base is obtained by transmitting the force which the return spacer between the rigid upper slats and the flexible lower slat.
  • the variable spacing of said return spacers makes it possible to obtain the desired flexibility depending on the location chosen. Indeed, it is possible to bring the spacers symmetrically, for example on the part corresponding to the kidneys and on the other hand to move them apart on the part corresponding to the nape of the neck. There is thus a very wide possibility of combination.
  • groups have been described comprising two rigid upper slats for a flexible lower slat; this example is not limiting, the number of slats of each group can vary as well as their width, it is the same for the rigid bars which are described in square section but which can be cylindrical or of rectangular section or crenellated round.
