Description

The invention relates to a three-point bridge suspension repository for flexible and rigid crossbars in bed subframes and has the special design features:

  • I. Large, slightly progressive adjustment stroke h ≈ H / 2 with H = overall height with a fixed support and h ≥ H with a moving support of the central spring element.
  • II. Great angular adaptability of the integrated cross bar caps around the vertical central position as well as good lateral stability.
  • III. Division of the brackets from adjacent bridge elements by hinge-like teeth of the rotatable eyelets and integration of the cross bar caps in the bridge elements or axis connection to separate rotatable caps.
  • IV. Very variable adaptation to the weight and weight distribution of an overlying body.
  • V. Use as a large-stroke support element on moving supports such as the pneumatic, resilient surface bearing (PCT / EP application 94/02772) or a flexible / elastic band for the interactive coupling of several / all cross bars.
  • Normal rubber / plastic repository caps for crossbars of slatted bed base frames are based on the two-point bracket on bolts in standardized grid holes of 60 mm, 64 mm etc. spacing. Various constructions with single and double arches and / or round and oval eyelets are known as flexible / elastic elements with a total adjustment stroke of 5 to a maximum of 20 mm.
    Other two-point single or double strips - repositories have flexible necks for ± 25 ° angle adjustment with very little vertical stroke. In the critical shoulder area, special adjustment elements with strongly progressive (spiral) spring travel of 15 to 25 mm stroke are used, which are additionally inserted between the lower frame spar and cross bar cap and lead to a shortening of the cross bar span. Double cap bridges without retaining bolts between each of the two held cap repositories are also used to lower the shoulders.

    European patent application EP-A-0 575 721 discloses one Two-point repository, in which an upper support part over a middle web is pivotally connected to a foot part. It differs completely in structure from those described here Repositories since it has no bridge elements.

    German patent application DE-A-39 32 340 is a two-point repository for three spring wooden slats, in which the three receiving caps are connected via cylindrical, elastic intermediate pieces to the two fastening elements and an arched upward web. The three mounting caps are connected to each other by webs. The fastening elements are not rotatably mounted around the brackets and a stationary or the formation of a moving support is not provided.

    European patent application EP-A-0 366 065 describes a slatted bearing body with a diamond-shaped connecting framework, which is inserted between a frame-fixed two-point fastening section and a slatted bearing section.
    A tensile additional spring section connects free corner points of the connecting framework or a separate sleeve-shaped additional spring section is arranged in between.
    At first glance, two exemplary embodiments Fig. 5 (11) and 7 show a certain similarity to the Triflex repository at first glance; this also applies to the end cap described in French patent application FR 26 70 101.
    In all three end caps, the two-point mounting section consists of two cross connections not rotatable about the mounting axes or of a cross connection and an arch segment. Between the cross connections there is a hole for a third crossbar, or in the French application there is a hole for a reinforcing crossbar above the arch segment. In the French application, the upper spring element consists of two elbow-shaped arms on which two structurally separate arms or a bridge connected slatted pockets sit.
    In the version of Fig. 5 of EP-A-0 366 065, a thick material arm is formed in the middle between the additional spring section and on the fastening section and can represent an elastic stop for the bearing section in the event of very strong deflection.

    In none of the examples can a central spring element form a separate, rotating support under load or be supported by a stationary or moving support, a flexible belt or the pneumatic, resilient surface support, since no (third) support is provided, and that possible vertical movement of the lower part of the central spring element is far too low for a meaningful, moving support function.
    All of the examples given therefore lack the inventive character of the three-point bridge suspension repository.

    None of the exemplary embodiments described in the cited documents has the further degree of freedom of rotation about the support axis claimed here, which enables a new quality of the deformation and thus quantity in the stroke h H H of the Triflex repository.
    None of the repositories or crossbeam caps known in the prior art have more than two of the five properties of the Triflex repository listed at a time, and none of them achieves the stroke adaptability of point I or the use of point V.

    The aim of the present invention is therefore to provide a crossbar repository that fulfills all of the features specified under items I to V. This task is solved with a three-point bridge suspension repository for flexible and rigid crossbars in bed subframes according to the main claim. Advantageous refinements can be found in the subclaims.

    The properties I to V according to the invention are based on the following design features:

  • I. The variable long-stroke adjustment results from the flexible bridge elements and the interaction with the spatially separated central spring element, as well as the possibility for the latter to use or omit a fixed support. The bridge elements and possibly the central spring element are connected with eyelets that can be rotated around the Axis of the mounting bolts are arranged.
    The rotatability of the bridge elements enables less deformation of the elastic material as a function of the stroke movement and thus a larger stroke with a lower overall height than with conventional repositories. This also results in higher wear resistance. The spring effect due to the rotatability is less than linearly progressive and thus results in a faster and easier rough contour adjustment to the body lying on it.
    The central spring element, consisting of arch segments, or in cooperation with the cross connections to the two symmetrical bridge elements, can take over the function of a moving support, which enables a stroke h ≥ H, with H = overall height. In the case of cross-connections, lowering is easier, the higher these are set.
  • II. The large angle adjustment is achieved by folding the flexible bridge elements and by rotating the connected eyelets around the retaining bolts ; the good lateral stability is achieved by the cross connections to the central spring element or by designing the central spring element as an arch segment.
  • III. The integration of double bar caps in the upper part of the bridge elements is possible due to the span of the Triflex repository without reducing the long-stroke adaptability. The normal grid holes can be used for the brackets of the bridge elements and, if necessary, for the fixed support of the central spring element.
    In the latter case and in the case of the special migratory supports, two successive bridge elements from adjacent repositories advantageously share the retaining bolts attached to the bed frame, with a hinge-like toothing of the eyelets providing good support even during the intended rotation.
    By means of eccentric connectors, these holding and support points can be lowered at or below the lower edge of the bed frame.
    In the case of the pneumatic, resilient surface bearing, in which a tubular container as a moving support for the central spring element is located in a U-profile spar, it can be advantageous to connect separate double cross bar caps rotatably via an axis to the bridge suspension repository. In this way, the axle can be lowered into a suitable recess in the inner leg of the U-profile spar and thus the full stroke h> H of the moving hose support can be used without increasing the installation height.
  • IV. The very variable, individual adjustment to weight and weight distribution, especially in the shoulder and pelvic area, can be done by
    • Placing or removing the fixed support for the central spring element,
    • Inserting or clipping suitable reinforcement elements into the recesses of the central spring element, the bridge or cross-connection elements of a Triflex repository.
    The individual adjustment can be done with the help of a pressure measurement system.
  • V. Triflex repositories can be used for the interactive coupling of the repositories on the two special moving supports, the pneumatic, resilient surface support and the flexible, elastic belt support, which is particularly advantageous and utilizing the large stroke.
    In both cases, a stroke adjustment h ≈ H is achieved.
  • The Triflex repository can be used primarily in the high-comfort slatted frame subframe with flexible spring wooden slats or rigid crossbars. It enables a significantly improved lying quality compared to normal end cap bearings, especially in the shoulder and buttocks area in the lateral position and in the back, neck and head area in the supine position of the human body. The use of additional shoulder lowering elements is completely unnecessary. In all cases, the thickness of the mattress topper can be reduced to approx. 80 to 100 mm, which ensures adaptability and improves cross-ventilation. The Triflex repository can also be used in sick beds and comfort beds with and without a support. In the latter case, direct molding to the cross bars or a material composite between the (plastic) repository and cross bar (s) is possible.
    In combination with the two special supports, see above, for the interactive coupling of all repositories plus crossbars, this results in previously unattainable lying comfort with optimal adjustment and positive support in all lying positions.

  • Figure description

    Fig. 1a shows a three-point bridge 2.2 'suspension end bearing with the mounting bolts 3, 3', which are attached to a bed frame 4. The central spring element 1 with a groove 30 for clipping in reinforcing elements 10 (FIG. 1b) can also be fastened to the spar 4 as a fixed support via a retaining eyelet 5.
    The mounting eyes 9, 9 'in a hinge-like division are rotatably mounted on the bolts 3,3'. Successive bridge elements 12, 12'etc. the mounting bolts 3.3 'can share. The cross bar caps 7, 7 'are advantageously integrated in the upper part of the bridge elements 2, 2' and can be close and <180 ° to each other in the unloaded state at an obtuse angle. Deformation under load to an angular position α ≥ 180 ° is possible and is facilitated by an undercut 8. Cross connections 6, 6 'between the central spring element 1 and the bridge elements 2, 2' ensure a guided adjustment stroke by buckling the bridge 2, 2 'and connection 6, 6' elements and ensure good lateral stability.

    1b shows two possible reinforcing elements 10 and 10 ', those for (individual) adjustment to body weight and -Weight distribution of the bed user in the central spring element 1 or between the bridge 2 'and the cross-connecting element 6 'can be clipped or inserted. The web 30 'snaps thereby in the groove 30.

    Fig. 2a shows a three-point bridge 12.12 'suspension repository with integrated double cross bar caps 27,27' and the central spring element consisting of two symmetrically arranged large arch segments 31,31 ', between which a moving support 35 in the form of two converging ones smaller arc segments 33,33 'is arranged. The mounting eyelets 9,9 ', on which the lower part of the bridge elements 22,22' and the arches 31,31 'end, are rotatably arranged on the mounting bolts 3,3' and allow an inward directed deformation of the elements 31,31 'and 32.32'. In cooperation with the arches 33, 33 ', which form the moving support 35, a stroke h H H / 2 results. When the angle is adjusted, the moving support 35 takes over
    also the function of a stop, in that it lies laterally against the arch segments 31, 31 'and thus limits the angular deflection.
    This repository has a large, very balanced stroke and angle adjustment with good restoring effect and lateral stability.

    In Fig. 2b is a three-point bridge suspension repository with integrated cross bar caps 27,27 'with outwardly directed continuous deformation of the bridge elements 32,32' and the arc segments 41,41 'and 43,43' of the central spring element, which in turn is made possible by rotating the eyelets 9,9 'on the mounting bolts 3,3'.
    The moving or stationary support 45 has a stabilizing function during the angle adjustment. If the support 45 is used only as a moving support, the eyelet 46 can advantageously be omitted.
    With this version, a Hüb of h ≈ H / 2 with a fixed support and of h = 2H / 3 can be reached with moving support 45. The angular adjustment is also greater when the support moves than in the version in FIG. 2a, but at the expense of lateral stability.

    3 shows the cross section through a three-point bridge 12, 12 'suspension end bearing with separate double cross bar caps 17, 17 ', which are rotatable on a connecting axis 20 are inserted, which are centered over the central spring element 11 is arranged. A flat support element 28 lies on the hose-like container 15 as a moving support one pneumatic, resilient surface bearing. The bed frame side rail 14 is here to accommodate the one with an incompressible Medium-filled hose 15 designed as a U-profile, at its upper leg edges, the brackets 13, 13 'attached are. These brackets can be in the two legs of the U-profile bars 14 can be riveted or screwed in and carried so to a torsional stability of the bed frame spar.

    In the upper half of the bridge elements 12, 12 'attached cross connections 16, 16' allow easy, guided lowering of the connecting axis 20 and the separate cross bar caps 17, 17 'under pressure under the brackets 13, 13', the axis 20 in the recess 34 immerses the inner U-profile leg and the hose container 15 and the central spring element 11 are deformed to about half of their overall heights in the unloaded state. In this way, a total stroke h of the bridge suspension repository is achieved from h> H.
    The lifting movement is mainly made possible by the rotation about the axis of the brackets 13, 13 'and by elastic deformation of the central spring element 11 and the bridge elements 12, 12', the good lateral guidance (in the longitudinal direction) by the extensive length constancy with elastic deformation of the cross-connection elements 16 , 16 '.
    The return to the unloaded normal position shown in FIG. 3 takes place via the elasticity of deformation of the end bearing, in particular the central spring element 11, and via the pressure and height adjustment in the hose container 15.

    For the bridge suspension repositories permanently elastic deformation Materials are used, such as rubber, vulcanized EPDM rubbers, as well as plastics like Polyurethane foams or SEBS (styrene-ethylene-butadiene-styrene). A low deformation hysteresis and retentivity of the material should be aimed at. In the case of the bridge elements 2, 2 ' Integrated cross bar caps can do this from something harder (plastic) material and seamless in the elastic bridge 2, 2 'and central spring elements 1.21 pass over. Such composite techniques are common today used.

    The separate end caps 17, 17 'advantageously consist of harder, hardly or slightly twistable (plastic) Materials; if necessary, a sliding bush can be used to to ensure the rotatability about the connecting axis 20. The Axle can be made of metal, aluminum, brass or steel or else made of torsion-resistant plastics with fiber inserts if necessary.

    4a shows the cross section through two bridge suspension end bearings with integrated double transverse bar caps 27, 27 'and 27'',27''' with a common flexible moving belt support 25, one in the unloaded and the other time in the high pressure p - loaded Status. Adjacent bridge elements 2, 2 '' share the mounting bolts 3 (3 'etc.). The support elements 18, 18 'are here advantageously designed as carriages with double rollers 19, 19' and 19 '', 19 ''', under which the flexible (elastic) band 25 can be moved.
    The belt 25 rolls over roller bearings 29, which in this embodiment version are connected to the lower frame spar 4 below the mounting bolts 3, 3 ', 3''. The double-axle carriage 18, 18 'is advantageous compared to a single-axis, since it enables a more uniform and deeper lowering with less selective loading of the belt 25.

    The car has over the rollers 19, 19'etc. advantageously a roof, which prevents the cross connections 6, 6 'etc. or the central spring element 21, 21' from sitting on the rollers during lowering and thus preventing further rolling on the belt 25.
    The bridge elements 2, 2 ', 2''share, for example in hinge-like division into two, the mounting bolts 3, 3', 3 '', around which the mounting eyelets 9, 9 ', 9''are rotatably arranged. An undercut 24, 24 ', 24''of the overlapping shoulder of the bridge elements makes turning easier.

    4b shows a top view of the arrangement of a flexible band 25 over approximately 90% of the length of the bed frame 4, lying on the roller bearings 29 and connected to a coil spring 26 and 26 'as longitudinal expansion elements in the head and foot part of the frame.
    The hardness of the coil springs can be individually adjusted to the weight of the body lying on it. Hardened coil springs show - practically only in the elastic range - no signs of fatigue.
    The bridge suspension end bearings arranged between the roller bearings 29 are not shown.
    For the approx. 20 to 30 mm wide and 1 to 2 mm thick, flexible band 25, natural fiber or plastic fabrics or flexible, stretch-resistant plastics are suitable. For example, rubber, vulcanized rubber types or comparable elastic and flexible plastics can be used for the flexible, stretch-elastic tape.

    The interaction of the end bearings with the flexible (elastic) band arrangement results in a less than linearly progressive dependency between the change in tensile force ΔF and the length change Δl of the band per end bearing section 1, see FIG. 4a.
    Hooke's law for the elastic expansion of the longitudinal expansion elements 26, 26 '(possibly the elastic band itself) is ΔF = - D · n · Δl with n = number of belt bearing sections and D = elastic (spring) constant.
    A simple geometric consideration shows that the vertical change in stroke Δh of the strip is, to a good approximation, proportional to the root of the extension Δl of the stretched strip length l between two roller bearings 29; for the case Δh <l / 3 applies Δh ≈ (Δl · l / 2) 1/2 . Δl from equation (2) used in (1) results ΔF = - Dn (Δh / l / 2) 2nd · L / 2. Assuming Δh <l / 3 the factor (Δh / l / 2) <1; this also results in a decisive reduction in the linear tensile force to stroke change relationship (3) compared to linear progressivity, in particular in the rough stroke adjustment phase.
    Examples of the lowering Δh below the equilibrium height of the band 25 with l = 128 mm show the less than linear increase of Δl = (Δh / l / 2) 2nd · L / 2: Δh / mm 10th 20th 30th 40 (Δh / l / 2) 2 0.02 0.1 0.22 0.39 Δl / mm 1.6 6.2 14 25th

    This results in an initially slightly progressive coarse contour adjustment of several repositories and the connecting crossbars to the overlying body as well as their interactive coupling via the common support band 25. The drawn, negative stroke h at pressure p load can certainly reach the height H of the repository.
    The frame-fixed rollers 29 and the rollers 19, 19 'of the double-axle carriage ensure that the belt is largely (uniformly) loaded over its entire length and is not exposed to excessive loads in the area of individual repositories.
    The interactive coupling of all or more than 90% of the repositories and their large total stroke of h ≈ H enables

    • a pressure-free, resilient support of the body lying on the back and side,
    • very good support in the back, neck and thigh area on the back or in the hip and head area on the side,
    • the use of an approximately 80 to 100 mm thick mattress topper with good adaptability and cross ventilation.

    In addition to the mentioned stroke of the repository according to the innovation the adjustment stroke of the mattress topper and, if applicable, that of resilient cross bars. In particular, the interactive coupling of the Repository and crossbars over the whole or more than 90% of the The bearing surface of the bed frame provides a support for the spine and weight-relieving lying comfort. This is quite comparable to that of the pneumatic, 3 resilient area bearing and the PCT / EP application 94/02772 is reached.
