Definitions

  • the invention relates to a support device for a mattress, a blanket or similar support for the body, in particular a slatted frame, with a frame and flexible slats attached in the longitudinal direction.
  • Slatted frames are generally known as a support device for a mattress, in which slats of the same flexibility are arranged across the length of the frame supporting the slats transversely to the longitudinal direction of the body.
  • This support which is uniformly flexible over the length of the body, does not result in good preservation of the natural spinal curvatures of the lying body due to the differently heavy areas of the body.
  • the pelvic region With a very flexible support device, the pelvic region sags like a hammock, while with a less flexible support device the pelvic region can hardly sag, but for example the lighter upper body region can sink insufficiently to one side, with the result that the shoulder girdle is compressed.
  • the invention has for its object to provide a support device of the type specified in such a way that the natural spinal curvatures in the back and side position are retained on the lying body and there is a body-appropriate support.
  • the support device By dividing the support device in the longitudinal direction into three sections of different lengths, the support device is tailored to specific body regions. By supporting the longitudinal battens exclusively at their ends in the longer upper section corresponding to the shoulder and upper body area and in the shorter central section corresponding to the pelvic area, the ability of the support device to react on the side and back position is achieved in that fewer battens are acted upon by the body weight in the lateral position , so that the loaded slats bend more, while in the supine position the body weight rests on several longitudinal slats, which do not bend as much as a result.
  • Fig. 1 shows a side view of a slatted frame 1 with an overlying body, with a mattress, blanket, foam layer or the like underlay for the body omitted for clarity of illustration because of the arrangement between the body and the slatted frame 1.
  • the slatted frame 1 is divided into three longitudinal sections in the illustrated embodiment. The individual sections of the Slatted frames are designed with different degrees of flexibility depending on the weight of the body region lying on them. Section 2 of the slatted frame corresponds to the upper body region, the adjoining shorter section 3 of the pelvic region and section 4 of the leg region, this section 4 being designed longer than section 2.
  • section 2 Since the chest as a hollow organ is about three times lighter than the pelvis, section 2 is provided with particularly elastic slats, while less flexible slats are provided for the heavier pelvic region.
  • the leg region is particularly light, but it does not require very flexible slats to support it, so that, depending on the softness of the mattress, section 4 can also be made relatively rigid.
  • the head is not taken into account for the design of the section 2 assigned to the upper body region, because the head is supported separately by a pillow and therefore no longer influences the support of the mattress .
  • slats 5 extending in the longitudinal direction of the body are provided at least on sections 2 and 3, as shown in FIG. 2.
  • the arrangement of longitudinal slats 5 compensates for the different contact pressures in the back and side positions of the body reached.
  • the body lies on a large area on several longitudinal slats 5, so that a single longitudinal slat 5 absorbs only a relatively small proportion of weight or a small compressive force.
  • the contact surface is smaller or distributed over fewer longitudinal slats 5, so that there is a greater load on the loaded longitudinal slats and thus a greater deflection than in the supine position.
  • the longitudinal slats 5 can follow the natural curvatures of the spine, they have to be very flexible on the section 2 for supporting the upper body region, while in the area of the heavier pelvic region on the section 3 less flexible longitudinal slats are provided. Since there are no curvatures in the leg region, the design of section 4 is of minor importance. For example, in contrast to 2 according to FIG. 2, slats or a wooden plate extending transversely to the longitudinal axis of the body can also be provided if a sufficiently soft mattress is used as a body support.
  • the flexibility or upper body and pelvic region 2, 3 can be influenced by the width of the longitudinal slats 5 and / or the thickness of these slats.
  • the longitudinal slats can have a width of 3 cm.
  • a correspondingly large number of longitudinal battens can be provided, for example 20 battens per meter, the spaces between them being 1.5 cm between the battens.
  • the slatted frame is surrounded by a frame 6, on which cross struts 7 and 8 are attached to limit the central section 3, which support the longitudinal slats 5 of section 3 and one end of the longitudinal slats 5 of sections 2 and 4, respectively .
  • the opposite ends of the longitudinal slats 5 of the sections 2 and 4 are supported on the associated end faces of the frame 6. So that the longitudinal slats 5 can bend sufficiently downwards, the bearing surfaces of the slats on the frame or on the cross struts 7, 8 are chamfered downwards. If the ends of the slats 5 are inserted into receiving slots on the end faces of the frame 6, the lower surface of these slots is expediently beveled downwards in accordance with the bending line of the slats.
  • the ends of the slats 5 rest on the upper side of the cross strut 7, the on the Sections 2 and 3 staggered slats with their ends interlock.
  • 3 shows an embodiment in which the ends of the slats have a stepped or narrower end section 9, by means of which they rest on the cross strut 7.
  • a flexible band 10 is placed on the end sections 9, which is indicated in FIG. 3 by dashed lines. In this way you get a smooth, continuous contact surface in the back area without step or heel.
  • the cross strut 7 between section 2 for the upper body region and section 3 for the pelvic region is designed to be adjustable perpendicularly to the support surface, so that the cross strut 7 is shown in the plane shown in FIG of the slatted frame 1 can be lowered, as shown in FIG. 4, and is height-adjustable in this lowered position.
  • Upper body and pelvic regions are relatively rigid regions of the body. They are only relatively movable in between in the lumbar region. Depending on the load on this area, it is often pleasant and useful if this lumbar area does not follow the natural curvatures, but is flattened when lying down. For this purpose, an obtuse, flat angle between sections 2 and 3 is provided, which is of the order of 150 ° to 180 °. In a practical embodiment, the cross strut 7 is lowered by up to 4 cm with respect to the level of the slatted frame.
  • an eccentric 11 can be arranged under the cross strut 7, for example 5, which is rotatably mounted in the side cheeks of the frame 6 and bears with its eccentric surface on the underside of the cross strut 7.
  • a section for the engagement of a tool for turning for example a square section or the like, can be provided.
  • a pin or the like engaging in a bore can be provided.
  • slots or shoulders can be formed on the inside of the side cheeks of the frame 6 on an adjusting element which can be moved relative to the side cheeks of the frame 6 so that the cross strut 7 can be released and brought into engagement with this element again in another position.
  • Fig. 6 shows a continuous bar 12 made of latex, rubber or the like, which rests on the cross strut 7 and serves as a support for the ends of the longitudinal slats of sections 2 and 3.
  • This bar 12 is interchangeably attached to the cross strut 7.
  • it can have a cross section of 7 x 7 cm, and preferably three compression hardnesses of this elastic strip 12 are provided.
  • the overlying slat ends sink about 4 cm below the level of the sections 2 and 3 shown in FIGS. 1 and 6 when the body is loaded, with an average compression hardness about 2 cm and at one fixed embodiment, the slats remain in the plane shown in Fig. 1 with static load on the body.
  • the bar 12 acts as an elastic buffer.
  • this can be provided as an adjusting device for the angle shown in FIG. 4 between the sections 2 and 3 when the body is loaded.
  • the strip 12 can also rest on a wider support instead of the cross strut 7.
  • All slat ends are preferably mounted elastically in order to emphasize the difference between the broad back position and more punctiform side position and to cushion body movements even more elastically.
  • the lumbar region can be flattened in its curvature by a flat angle between sections 2 and 3, so that in this embodiment not only a compensation of the different pressure regions between the upper body and pelvis and a compensation of the contact pressure in the back and lateral position by the slats 5 arranged in the longitudinal direction of the body, but also the lumbar region is relieved.
  • the slatted frame described advantageously consists only of natural materials, such as wood, without metal components.
  • Section 4 for the foot region and section 2 for the upper body region can each be made adjustable and lockable at the outer ends, so that the upper body or the legs can be correspondingly higher.
  • the longitudinal slats 5 are expediently interchangeably attached to the frame 6 or the cross struts 7, 8.
  • slots are provided on the end faces of the frame 6 and on both sides of the cross strut 8 for receiving the slats 5, while the slat ends rest on the cross strut 7 in order to achieve a smooth transition.
  • the longitudinal arrangement of the slats 5, in particular on sections 2 and 3, also gives the further advantage that the width of the slatted frame 1 has no influence on the supporting effect or, in the case of a slatted frame with a width corresponding to that of a double bed, the same supporting effect is achieved at every point .
  • continuous longitudinal slats 5 can be provided which extend at least over the sections 2 and 3, these longitudinal slats being supported on the underside at the transition point between the upper body and pelvic region. Due to the different distances between the supports of these slats, there is a different degree of flexibility on sections 2 and 3.
  • the length of section 2 is 70 to 80 cm, preferably 75 cm, while the length of section 3 for the pelvic region is 55 to 65 cm, preferably 60 cm.
  • the elastically resilient, preferably arched, prestressed long slats 5 have a flexibility in the upper body area on section 2, which is a deflection of 3 to 5 cm, preferably 3.5 cm, under a load of 4.5 kg with a support length of 10 cm at one Latte corresponds.
  • the deflection is 1.5 to 3 cm, preferably 2 cm.
  • the slats are not rigidly clamped at the ends, but can move freely in the direction of bending.
  • the band 10 provided for fixing the slat ends (FIG. 3) is expediently designed such that pockets are formed by darts across a double-layer band, into which the stepped ends 9 of the longitudinal slats 5 are inserted.
  • Such a band 10 with pockets can rest on the cross strut 7 or the strip 12 without the need for further attachment by gluing or the like.
  • the longitudinal slats themselves can be made of wood, plastic, fiberglass or the like. Preferably wooden slats are used, which consist of three to five layers glued together.
  • the longitudinal slats of sections 2 and 3 and, if appropriate, section 4 can also be covered over the entire surface, for example with a fabric, but this does not impair the flexibility of the individual slats.
