Definitions

  • the present invention relates to a slatted-mattress having at least one double-deck slat unit, which comprises a first slat, forming a lower deck and a second and third slat, forming an upper deck of said double-deck slat unit, said second and third slat extending substantially in parallel with respect to each other and being separated by a gap, said first slat extending offset of said gap, and wherein a resilient compensation element is applied in a space between said lower and upper deck.
  • Such a slatted-mattress is well known as support for the mattress of a bed.
  • the double-deck slat units are generally used in the hip- or shoulder-zone of the slatted-mattress where the downward force applied by the body of the person lying on the mattress is the heaviest.
  • the use of a double-deck slat unit enables to exert a larger counterforce in those zones and thus to offer a better sleeping comfort.
  • the use of a resilient compensation element further increases the exerted counterforce.
  • the resilient element prevents that the second and third slat contact the first slat when too much downward force is exerted on the slatted-mattress.
  • a drawback of the known slatted-mattress is that the resilient compensation element supports unsufficient the upper deck. Indeed, in order to provide a good sleeping comfort, the second and third slats must be able to pivot around their attachments. Due to unsufficient support of the compensation element, the slats can pivot away from the compensation element and thus provoke abrupt shocks to the body of the person lying on the mattress. To reduce the probability of that pivoting away, the compensation element is made of a relatively hard material, which on its turn adversely affects the sleeping comfort as it reduces the resiliency of the second and third slat.
  • An object of the present invention is to realise a slatted-mattress offering an improved sleeping comfort.
  • a slatted-mattress according to the present invention is therefore characterised in that said compensation element forms a closed, substantially ellipse shaped loop, having a lower loop segment forming a tangent plane with said first slat, which lower loop segment is provided to rest onto said first slat, and having an upper loop segment crossing said gap and forming a tangent plane with said second and third slat for sustaining the latter. Due to its geometry, the ellipse shaped loop has good resilient properties so that sufficient compensation of an exerted downward force is obtained. Moreover, the tangent plane that the lower loop segment forms with the first slat, enables to adequately distribute the pressure exerted by the compensation element on the first slat.
  • the tangent plane formed by the upper loop segment enables to adequately support the second and third slat over the whole surface of the plane, so that even when the latter slat would pivot, it will still be sustained by the upper loop segment thus avoiding that the second and third slat pivot away from the compensation element.
  • a first preferred embodiment of a slatted-mattress according to the invention is characterised in that said resilient compensation element comprises a fixing member applied on a lower loop segment and is provided to fix said compensation element into said first slat.
  • said resilient compensation element comprises a fixing member applied on a lower loop segment and is provided to fix said compensation element into said first slat.
  • a second preferred embodiment of a slatted-mattress according to the invention is characterised in that said upper and lower loop segment show a decreasing thickness starting from a central position towards an extremity, in a direction substantially perpendicular to a plane described by said loop. This enables to provide a gradient in the resilient properties of the upper loop segment and thus to adapt the resiliency of the compensation element on a changing force applied by the second and third slat when they execute their pivoting movement.
  • a third preferred embodiment of a slatted mattress according to the invention is characterised in that at its longitudinal edges said resilient compensation element shows a larger thickness of the material of which it is made with respect to the remaining part of the element. This enables to have the compensation force increased upon increased downward force.
  • said loop extends in the longitudinal direction of said slats.
  • the compensation element can exert a movement that is in harmony with the one of the second and third slats.
  • figure 5 shows a cross-section through the compensation element in a direction substantially perpendicular to a plane described by the loop.
  • the slatted mattress 10 of which a section provided to be mounted in a hip-zone of a bed, is shown in figure 1.
  • the illustrated section comprises two lateral beams 4 and 5 on which support members 6 are mounted.
  • the support members are connected by means of pins 9 on the beams and have to carry a double-deck slat unit 11.
  • This double-deck slat unit comprises a first slat 1, forming the lower deck and a second 2 slat and third 3 slat forming the upper-deck.
  • the second and third slat are separated by a gap 12 and extend substantially parallel to each other.
  • the first slat also extends in parallel with respect to said second and third slat and is situated offset of the gap 12.
  • the second and third slat are situated at a distance situated between 2,5 and 5 cm from the first slat.
  • the first, second and third slat are made of resilient material, preferably laminated wood.
  • the support members 6 are also made of resilient material, preferably rubber, in order to provide good resilient properties to the slatted-mattress.
  • a resilient compensation element 7 is mounted between the lower- and the upper deck of the double-deck slat unit 11.
  • This resilient compensation element forms a closed, substantially ellipse shaped loop as is shown in figure 2.
  • a lower loop segment 14 forms a tangent plane with the first slat 1 and rests thereon.
  • An upper loop segment 13 forms a tangent plane with the second 2 and third 3 slat and sustains the latter.
  • the element 7 is dimensioned in such a manner as to cross the gap 12 between the second and third slat as is shown in figure 3. From the latter figure it can also be seen that an upper face of the element 7 is substantially oval shaped, which enables to extend over a substantial part of the width of the second and third slat.
  • the contact surface between the second and third slat and the upper loop segment 13 is sufficient large to enable a suitable distribution of a force applied on the slats of the upper deck.
  • the oval shape of the lower face of the element 7 also enables to provide a sufficient contact surface between the first slat and the element 7.
  • the element 7 is preferably provided with a fixing member 15 and the first slat is provided with an aperture 18 for receiving the fixing member 15.
  • the fixing member and the aperture are dimensioned such as to match with each other.
  • the fixing member is preferably formed by a protrusion cast in the same material as the one of which element 7 is made. This enables to easily manufacture the fixing member during a same casting operation.
  • the protrusion is provided with fins 19 and 20 for reinforcing purposes.
  • the fixing member By fixing the protrusion 15 into the aperture 18, the fixing member is anchored into the first slat and can not be displaced due to movements of the person lying on the slatted-mattress.
  • the element 7 remains positioned with respect to the slat unit and its compensation function is not affected by movements of said person.
  • the aperture is applied in the centre of the first slat and the protrusion 15 is also applied in the centre of the lower loop segment, which enables to fix the element 7 in a central position of the double deck slat unit.
  • the compensation force is applied in the centre of the slatted-mattress which is the most probable place where the person lies.
  • the central positioning also enables an equal distribution of the compensation force.
  • the upper and lower loop segment show a decreasing thickness starting from a central position i.e. around handle 8 and protrusion 18, towards extremities 21, 21' and 22, 22' in a direction substantially perpendicular to a plane described by the loop.
  • the element has a larger thickness in a region around handle 8 and protrusion 18 than at its extremities 21, 21' and 22, 22'.
  • the flexibility of the element 7 is thus different at the extremities what enables not only an easier demoulding but also to take into account the difference in force applied by the second and third slat.
  • the latter slats can pivot around their support member 6 what causes the slats to pivot away from the upper loop segment and thus to apply a different pressure on the element 7.
  • a lesser thickness at the extremities 21 and 22 a larger flexibility is obtained at those extremities so that even when the second and third slat have pivoted with respect to their initial position, they still are sustained by the element 7.
  • Figure 4 shows that the lateral flanges of the element 7 describe a hyperbola. This geometry enables on the one hand to form a sufficient contact surface with the slats and on the other hand gives the element good resilient properties.
  • the longitudinal edges 16 and 17 of the loop have a larger thickness than the upper and lower loop segment because more force has to be concentrated in this area.
  • the resilient compensation element extends in the longitudinal direction of the slats. In such a manner the element 7 contacts the slats over a large part thereof and thus provides a good compensation force over that whole part. If a person now lies on the slatted-mattress according to the invention, the pressure applied by his body on the slats will be transmitted to the resilient compensation element 7. The latter will be compressed causing the upper and lower loop segment to travel towards each other. By this compression a compensating force is applied on the second 2 and third 3 slat so that the downward movement of those slats will be limited. The person thus feels a better sustaining what offers him a better sleeping comfort.
  • the element is preferably made of plastic material such as polyamide or polyester reinforced by glass fibres. Of course other materials such as wood or steel could also be used. It is however essential that the used material has resilient properties.
