Definitions

  • This invention refers to an elastic structure for slat-type bed rests.
  • slat-type bed rests are available which are laid out across a frame and tied up to it by rabbets or elastic joints.
  • the slats may be of a rigid or elastic type, weakly curved upward so as to allow a favorable sagging action.
  • DE 296 11 876 U discloses the features of the preamble of claim 1.
  • the purpose of this invention is to eliminate the mentioned drawbacks, i.e. to produce an elastic structure for slat-type bed rests, capable of improving, with respect to the known technology, the adapting capacity of a bed rest to the stresses of a stretched-out body.
  • Another purpose of this invention is to produce an elastic structure for slat-type bed rests, capable of optimizing their reactivity, adjustability and adaptability and of combining them with the requisites of a bed-rest based on elastic slats.
  • a further purpose of this invention is to indicate an elastic structure for slat-type bed rests, capable of perfectly adapting the bed rest to the configuration of the spinal column.
  • An additional purpose of this invention is to indicate an elastic structure for slat-type bed rests, in which the slats' sensitivity to the body's stresses is substantially enhanced, while leaving the slats' inherent elasticity unchanged, and therefore achieving a permanently high standard of comfort for the user under any circumstances.
  • Another purpose of this invention is to indicate an elastic structure for slat-type bed rests suitable for preserving, in a static reclining position, the S-shaped configuration typical of the spinal column's static upright position, regardless cf the body's weight and the resting positions assumed by the user.
  • the elastic structure which is the object of this invention advantageously offers to enhance the bed rest's capability of adapting to the stresses of a stretched-out body by a solution allowing it to optimize its reactivity, adjustability and adaptability while combining them with the traditional advantages of a slat-type bed rest.
  • the longitudinal girders of the bed frame are provided with structures made of elastic material, composed of two opposed arches connected to each other in at least one point.
  • a first arch By rotating a pin connecting the two arches, a first arch can be set in tension while making the other rigid, so as to vary the first arch's elasticity at will, depending on the weight of the person and of the body's anatomical portion the bed rest's section has to be sustained.
  • the bed rest referred to in this invention is preferably produced by using flexible multiple-layered slats made of curved and steam-pressed beech wood, capable of perfectly adhering, due to their permanent elasticity in time, section-by-section to the curvature of the spinal column, while sagging only where needed and allowing the latter to maintain an orthopedically correct configuration in every position assumed by the sleeping body; alternatively, the slats are built in solid wood or other appropriate elastic material, not excluding reinforced plastic materials, for example fiberglass; in any case, the greater the number of slats, the more effective their action.
  • the slats are connected, by pivoting joints made of shockproof and undeformable material, to a robust all-wooden frame, so as to prevent the diffusion of electromagnetic impulses throughout the structure and guaranteeing a comfortable rest.
  • the robust insulating frame totally eliminates squeaking, it cannot produce rust and safeguards the integrity of the mattress.
  • each elastic structure is connected to only one extremity of each slat, alternatively to the right or left-hand side of the mentioned vertical axis, along the entire frame of the bed rest.
  • 10 generally indicates an elastic structure for a slat-type bed rest according to this invention
  • 20 indicates a curved slat, slate or rib inserted in a frame produced to support a mattress and to hold an elastic structure, composed of longitudinal girders 40 set in place by fastening screws 70 and sealing dowels 80, capable of being inserted in seats obtained by milling the longitudinal girders 40.
  • the slats 20 are preferably made of steam-heated and pressed beech wood.
  • this invention provides for the use of a frame profiled in such a manner that the extremities of the slats 20, inserted in appropriate and as such known slat holding elements 30, 31, outline the perimeter of the bed rest; and that the mentioned frame moreover exhibits a width inferior to the longitudinal size of the slats 20 and is set in a position underlying the same.
  • 30 indicates a swiveling type slat holding joint, preferably made of a rubbery material and comprising two first seats 33, 34, into which the extremities of the slats 20 and a portion of the elastic structure 10, respectively, insert themselves according to the present invention.
  • the slat holding joint 30 is fitted with an intermediate passing hollow, indicated by 35, whose function is to allow the mentioned joint 30 to flex in a vertical sense.
  • the slat holding element 31 also preferably made of a rubbery material, comprises of an insert 36, in which an appendix of the elastic structure 10 and a C-shaped sleeve 37 acting as a hinge for one of the extremities of the slat 20 can be inserted.
  • a spherical element 33 capable of rotating upon itself is inserted between the sleeve 37 and the insert 36, so that it guarantees a flexing motion of the slat 20.
  • the structure 10 for a slat-type bed rest 2C which is the object of this invention, is made of elastic material, preferably of a plastic material, harmonized metal or multiple-layered wood and built in a single piece in a curved form, comprising two elements or curved branches 50, 60 opposed to each other.
  • An upper curved element 50 is profiled so as to allow a flexing of the same with respect to the girder 40 of the bed rest's frame, amounting to at least 50 mm.
  • a lower curved element 60 acts as a stabilizing element and rigidity adjuster; the turning of the nut 95 of a bolt 90 connecting the two curved elements 50, 60 to each other while passing through a hole 91 carved out of the upper element 50 and a threaded hole carved out of the lower element 60 makes it in fact possible to stretch the lower element 60, thus stiffening the upper element 50.
  • the distance marked X between the upper face of the girder 40 and the median longitudinal axis of the slat 20 inserted into the seat 33 amounts to 80 mm
  • the distance Y between a vertical axis A passing through the center of gravity of the girder 40 and a point of the structure 10 indicated by 69 and substantially set by an area of contact between the two branches 50, 60 or between an upper branch 50 and the imaginary extension of the lower branch 60 set on the side of the slat holding joint 30, 31 substantially amounts to at least 10 centimeters.
  • the minimum distance Z between the lower face of the slat 20 and the structure 10 by the girder 40 preferably amounts to 50 mm, while the distance K between the axis A and the extremity of the sleeve 37, in which the slat 20 is inserted, preferably amounts to 15 cm.
  • the branch or curved upper element 50 of the elastic structure 10 is fitted with grooves 45, each of which may optionally hold an extremity of the lower branch 60, by using a U-shaped insert set opposite the area indicated by 69.
  • the curved elements 50, 60 do not touch each other opposite the area 69, and the turning of the pin 90 makes it possible to act on the branch 60, which functions as a support to stiffen the element 50.
  • figure 4 represents an embodiment of the structure 10 similar to that illustrated in Figure 1, where however the two curved elements 50, 60 are connected to each other in a reverse manner with respect to that shown in Figure 1.
  • the elastic structure 10 for a slat-type bed rest 20 is suitable for combining the advantages of a bed rest fitted with elastic slats 20 with an optimum reactivity, adjustability and adaptability, while enhancing the bed rest's capability to adapt itself to the stresses of a stretched-out body and allowing it to achieve an absolute adaptability to the configuration of the spinal column, which thereby maintains its most natural setting even in a stretched-out position, independently of the body's weight or sleeping position.
  • the use of the elastic structure 10 makes it in fact possible to regulate the elasticity of the curved upper element 50 at will, depending on the weight of the person and of the body's anatomical part the bed rest is destined to support.
  • the wide vertical excursion of the slats 20 allows the spinal column in a static reclining position to maintain the same S-shaped configuration which characterizes its static upright position, regardless of the body's weight or resting position.
