Definitions

  • the invention relates to a lying surface for a bed or the like according to the preamble of patent claim 1.
  • Such a lying surface has become known, for example, from CH 663 339 or PCT WO 88/04905.
  • the support element When the slats are loaded, the support element is therefore pulled inwards against the inner side part of the vertical guide and thus prevented from its vertical displacement in such a way that a spring action which is important in this load area is not, or if at all, only given to a limited extent.
  • the slidable connection between the individual slats with the corresponding support elements prevents these slats from bending in the required manner because a shortening of the axial slat length required for the deflection is not possible.
  • the present invention is therefore based on the object of developing a lying surface of the type mentioned in such a way that excellent suspension properties and an optimal adaptation of the lying surface to different body contours with different body weights, i.e. also with punctiform loading or loading of individual slats, are achieved without this vertical displaceability of the support elements and the deflection of the individual slats are impaired.
  • the invention is characterized in that a recess is now provided in the upper part of each support element, in which the ball head laterally engages, which is mounted there displaceably, the ball head being connected to a shaft which in turn is connected to the end face is connected to a crossbar.
  • An essential feature of the present invention is that a reduction in the axial length when the slat bends is compensated for by the fact that the ball head is arranged displaceably in the recess of the support element. In this way, the slats are not clamped axially, but can spring freely.
  • the slats are also in the each end-side recess pivotally mounted, so that there is a free deflection of the slats here.
  • the slats are of course also rotatably mounted, so that an optimal adaptation to the body contour of the user is guaranteed.
  • a pin is arranged on each support element in the lower part, which serves as a pull-out protection. This pin reaches through a slot in the inner side part, which limits the maximum extension upwards by a stop.
  • the lower side of the support element is designed as a U-profile, in order to achieve lateral guidance of the strips through a U-profile-shaped receptacle.
  • the base leg is designed as a rounded contact surface which, in particular in the event of strong deflection, does not come into contact with the belt without sharp edges and thus avoids large mechanical loads on the belt.
  • each support element initially rests on the upper band part of the upper band. If the load increases, the upper band stretches, whereby the support element is displaced vertically downward in the guide grooves of the side part and the support element then comes not only into contact with the upper band part, but also with other upper band parts of a second band.
  • each support element is assigned a progressive suspension characteristic in the vertical direction.
  • Such a lying surface can thus be used for all body weights and even the heaviest body weights are still adequately cushioned without the support elements hitting the bottom stops of the side parts.
  • two self-contained bands are used, the band parts each taking a mutual, vertical distance from one another.
  • a length-elastic tape material such as B. a knitted or woven rubber band can be used.
  • a length-elastic tape material such as B. a knitted or woven rubber band
  • only little length-elastic tapes can be used, such as. B. woven textile tapes, plastic tapes with appropriate length elasticity and the like.
  • the length of the closed bands does not extend over the entire length of the lying surface, but if the lying surface is divided into itself.
  • Such Unterteilunfg comes z. B. in a known manner for the head area to the shoulder, from the shoulder area to the lumbar region and from the lumbar region to the foot area.
  • the self-contained tapes can be assigned to each of these areas, so that, for example, if the bed surface is divided into three areas, each area is assigned a tape arrangement of the type described.
  • each area can be assigned a different elasticity.
  • a slatted frame 1 (see FIG. 4) is essentially formed from Slats 17, which are articulated and slidably mounted with their end faces in a respective support element 22.
  • the support elements 22 are displaceable in the vertical direction and resiliently mounted against the force of bands 7, 7a in each side part 2, 3.
  • Each side part consists of two half-shells, with an outer side part 2 and an inner side part 3 being defined.
  • the inner side part 3 is directed towards the bed surface, while the outer side part 2 is connected to a bed side, not shown.
  • a recess 4 is defined between the two side parts 2, 3 (see FIG. 7), in which the guide for the support elements 22, as well as the guide for the tapes with the rollers 5, 6 and the tapes 7, 7a are arranged themselves.
  • Each support element 22 is guided displaceably in a groove 11 machined in the vertical parts in the side parts 2, 3.
  • the parting line 40 between the side parts 2, 3 is shown in FIG. 6, for example.
  • each side part consists of a wooden body with an approximately rectangular or square cross-section, with a recess 12 for the engagement of the ball head 15 of the slat 17 being incorporated in the upper part, while the lower part of the support element is designed as a rounded support 8 with which the support element 22 on the different, at a mutual distance 29-32 one above the other arranged bands 7, 7a can be brought to rest.
  • the support 8 With further vertical displacement of the respective support element 22, the support 8 takes the upper band part 37 downwards and the support 8 then strikes the upper band part 37a of a second band 7a arranged below it.
  • the distance 30 is also overcome and the two band parts 37, 37a meet with the lower band part 38a of the middle band 7a.
  • a high restoring force is thus exerted on the support element 22 upwards, so that the support element 22 can also withstand the heaviest body weights in a punctiform manner due to the progressive suspension described and still springs.
  • the further spring travel is defined here by the distance 32 between the lower band part 38 of the band 7 and a lower stop surface 41 in the side part 2.
  • Each band 7, 7a is designed as a closed band.
  • the upper band 7 is guided over the deflection rollers 5, the deflection rollers being arranged evenly distributed over the axial length of the side part 2, 3.
  • the suspension hardness of the belts 7, 7 a can also be adjusted.
  • two support elements 22 each rest on free band parts 37, 38 and 37a, 38a of the bands 7, 7a.
  • rollers 5, 6 with corresponding shaft ends are rotatably mounted in associated bores 26 in the side parts 2, 3.
  • the side parts 2, 3 are otherwise connected to one another by pins 24, which pins 24 are arranged, for example, in the inside of the side part 2 and which engage in associated bores 25 in the inside of the other side part 3.
  • a pin 27 (see FIG. 8) is arranged on each support element in the lower part. This pin 27 engages through a slot 9 in the inner side part 3, and according to FIG. 7 it can be brought into contact with the lower edge of a stop 28 in the extended position of the support element 22. This avoids that the support elements 22 are pulled out of their grooves 11 in the side parts 2, 3.
  • the groove width 39 of the groove 11 is chosen to be larger than the slot width 36 of the slot 9 in order to prevent the support elements 22 from falling out of the groove 11 toward the front.
  • each slat 17 is guided in the direction of arrow 18 (in the direction of its axial length) via a ball head 15 in the recess 12 of the support element 22.
  • the ball head 15 also allows the bar 17 to be articulated in the direction of arrow 19 and in the direction of arrow 20.
  • Each slat 17 can thus individually adapt to the body contour lying thereon, as shown in FIG.
  • a stop limitation is provided for the greatest deflection.
  • the underside of the slat 17 then strikes a bar 23 which is arranged on the inside of the inner side part 3.
  • the bar 23 is with a z. B. made of felt impact damper 16.
  • An impact damper 42 is also incorporated into the top surface of the side parts 2, 3.
  • the ball head 15 is connected to the crossbar 17 via a shaft 14, the shaft 14 being rotatably held in the bore 21 in the crossbar 17.
  • the support 8 is designed on the lower side of the support element 22 as a U-profile and thus forms a U-profile-shaped receptacle 35.
  • the base leg is formed by the rounded support surface 8, while the side legs are formed by the side lugs 33, 34 of the support element 22.
  • the tape Due to the rounding of the support 8, the tape is thus bent gently and the support 8 follows the tape deflection in its contour, which ensures a long service life for the tapes.
