  • the object of the present invention is to prevent back complaints in a user.
  • the object of the present invention is also to improve a comfortable sitting, lying or sleeping position of the user.
  • a simple embodiment of the present device comprises a retaining bracket for securing an object against an underside of a sprung slat in order to adjust/set the stiffness of this sprung slat.
  • the object is connected against an upper side of the sprung slat. Connecting against an underside is advantageous, since an existing arrangement, e.g. a mattress in a sofa bed, is not impeded.
  • the sprung slat is mounted in a slatted base.
  • 'Sprung slat' is to be understood as a term known in the art, also known simply as 'slat', which denotes a carrier having a body as well as mattress supporting function within a slatted base or frame.

  • a slatted base frame is substantially rectangular in shape and the sprung slats are extended transversely in several strips in this slatted base.
  • a slatted base is often gripped by a frame, such as a frame of a bed, chair or sofa bed.
  • a traditional slatted base has the main function of evenly distributing the weight of a user so that they comfortably sit, lie down, sleep, etc.
  • the inventors note that when a user has, for example, back complaints, it can however be very advantageous to adjust the stiffness of different slats within a slatted base. This makes it possible to optimise the local support of a mattress for each user. The inventors note that this results in back complaints being found much less.

  • a simple embodiment of a slatted structure comprises a sprung slat, an object, preferably a sprung slat support, and a device comprising the retaining bracket as described herein for adjusting the stiffness of said sprung slat.
  • said object is connected to an underside of said sprung slat.
  • the stiffness also called the 'rigidity' or 'elastic deformability', of the slatted structure is determined by the stiffness of the sprung slat, the stiffness of the object as well as the force with which both are connected by the retaining bracket.
  • sprung slats have been curved along their longitudinal axis. Such curvature increases the stiffness of a sprung slat.
  • sprung slats are mounted in a slatted base such that the curvature points upwards.
  • the stiffness or rigidity of such sprung slats can be further increased by also providing an upward directed curvature along a width axis of these slats.
  • At least a portion of an inner surface of said upper portion is curved away from said bracket retaining region.
  • Such a configuration provides greater force on a central portion of the object and, consequently, also a central portion of the sprung slat.
  • Such pressure distribution further increases the rigidity of the slat structure by providing a curvature of such slat along a width axis.
  • at least a portion of an inner surface of said bottom portion is curved toward said bracket retaining region. Such a configuration provides greater force on a central portion of the object and, consequently, also a central portion of the sprung slat.
  • Such pressure distribution further increases the stiffness of the slat structure by means of a curvature of such slat along a width axis.
  • the curved bottom portion is a spring element.
  • Such a spring element prevents damage to the sprung slat and/or the object through an even pressure distribution. Moreover, a better clamping can be obtained between the sprung slat and the object, so that they form a solid whole.
  • one or more retaining brackets can be connected to the same sprung slat.
  • other connecting elements can also be used in addition to the retaining bracket. Examples include strips of textile, plastic, etc. that are clamped around the sprung slat and the object.

  • the slatted structure can be connected in a slatted base of, for example, a chair, bed or sofa bed.
  • the retaining bracket is substantially cubic or beam-shaped.
  • such a bracket may be cylindrical in shape.
  • the optimal shape of the retaining bracket is determined by the shape of the sprung slat and the object.
  • a sprung slat and sprung slat support are elongated and beam-shaped.
  • An optimal complementary shape for such sprung slat and sprung slat support is substantially cubic or beam-shaped.
  • the sprung slat and sprung slat support In order to connect the retaining bracket to such sprung slat and sprung slat support, the sprung slat and sprung slat support must be joined together such that the longitudinal axis of both slats are parallel.
  • the retaining bracket is subsequently positioned transverse to a longitudinal direction of the sprung slat and sprung slat support, i.e., the width axis of the retaining bracket is provided perpendicular to the longitudinal axis of the sprung slat and sprung slat support.
  • a simple embodiment of the retaining bracket is adjustable between an open position and a closed position by pivoting at least a portion of said retaining bracket. This makes the present invention easy to install.
  • the bracket retaining region is enclosed by said bottom portion, said first and second side wall portions and said upper portion when said retaining bracket is in the closed position. In the open position of the retaining bracket, the bracket retaining region opens along an outer circumference.
  • the adjustable portion of the retaining bracket pivots substantially in a frontal plane of the retaining bracket.
  • the adjustable portion of the retaining bracket can pivot in any plane.
  • the retaining bracket is adjustable between the open position and the closed position by pivoting the adjustable portion of said retaining bracket outward from the bracket retaining region.
  • the retaining bracket is adjustable between the open position and the closed position by pivoting the upper portion of said retaining bracket outward from the bracket retaining area.
  • Such a configuration opens up the bracket retaining region at an upper side allowing for easy insertion of the slats into the bracket. With an already mounted sprung slat, the upper portion can for instance be hooked onto the upper side of the sprung slat, after which the two side portions and the bottom portion are clamped around the sprung slat and the object.
  • the retaining bracket is pivotally adjustable between the open position and the closed position by opening and closing said retaining bracket at a first and second closing end provided on said retaining bracket.
  • a locking device is provided at said first and second closing ends for securing said retaining bracket in a closed position. Such a configuration prevents the retaining bracket from falling open accidentally.
