Definitions

  • Triflex three-point bridge suspension repository for crossbars in bed subframes with uses Triflex three-point bridge suspension repository for crossbars in bed subframes with uses.
  • the invention relates to a three-point bridge suspension repository for flexible and rigid crossbars in bed subframes and has the special design features:
  • 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.
  • 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.
  • the end cap with two-point holder described in French patent application FR 26 70 101 has a certain resemblance to the Triflex end bearing, but consists of two spring elements lying one above the other, arranged in a center Hole eyelet for holding a round reinforcement crossbar, e.g. made of fiberglass, converge.
  • the upper spring element consists of two symmetrically arranged, elbow-shaped arms, on each of which a structurally separate pocket for receiving the crossbars is seated.
  • the lower spring element is designed as a circular arch, above the zenith of which the round, central eyelet and at the outer ends of which the mounting eyelets are arranged for attachment to the side rail, which are additionally connected by a horizontal cross connection as a reinforcement base. Due to this structure, the principle of action of the double crossbar end cap described in FR 26 70 101 is necessarily completely different from the repositories described here; comparable properties are not claimed in the text of this application.
  • variable long stroke adjustment results from the flexible bridge elements and the interaction with the spatially separated central spring element, as well as from the possibility of using or omitting a fixed support for the latter.
  • the bridge elements or the central spring element are connected to mounting lugs which are rotatably arranged around the mounting bolts.
  • the large angle adjustment is achieved by folding the flexible bridge elements and advantageously 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.
  • these holding and support points can be lowered at or below the lower edge of the bed frame.
  • the individual adjustment can be done with the help of a pressure measurement system.
  • 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, in a particularly advantageous manner and using the large stroke.
  • the Triflex repository is above all highly comfortable with slatted frame subframes with flexible spring wooden slats or rigid transverse afford usable. It enables a significantly improved lying quality compared to normal end cap bearings, in particular 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.
  • FIGS. 1 to 4 illustrate the most important parts and functions of the Triflex repository. They show the basic structure in a schematic manner and each represent only one of several possible designs and uses.

  • the bracket eyes 9, 9 'in hinge-like division into two parts can advantageously be rotatably mounted on the bolts 3, 3'.
  • Successive bridge elements 12, 12 'etc. can be shared by the mounting bolts 3, 3'.
  • 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 O> 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 kinking the bridge 2, 2 'and connecting 6, 6 ' elements and ensure good lateral stability.
  • Fig. Lb shows two possible reinforcement elements 10 and 10 ', which can be clipped or inserted into the central spring element 1 or between the bridge 2' and the cross-connection element 6 'for (individual) adjustment to the body weight and weight distribution of the bed user.
  • 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 enable an inward-directed continuous deformation of the elements 31, 31 'and 32.32'.
  • a stroke h> H / 2 results.
  • the traveling support 35 also takes on the function of a stop in that it lies against the arch segments 31, 31 'on the side and thus limits the angular deflection.
  • This repository has a large, very balanced stroke and angle adjustment with very good lateral stability.
  • Fig. 2b is a three-point bridge suspension end bearing with integrated cross bar caps 27,27 'with outwardly directed continuous deformation of the bridge elements 32,32' and the arch 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.
  • the eyelet 46 can advantageously be omitted.
  • the angular adjustment is also greater when the support moves than in the version in FIG. 2a, but at the expense of lateral stability.
  • FIG. 3 shows the cross section through a three-point bridge 12, 12 'suspension end bearing with separate double transverse bar caps 17, 17 ' which are rotatably fitted on a connecting axis 20 which is arranged centrally above the central spring element 11.
  • a flat support element 28 lies on the tubular container 15 as a moving support of a pneumatic, resilient surface bearing.
  • the Bettu terrahmen side spar 14 is designed here for receiving the hose 15 filled with an incompressible medium as a U-profile, on the upper leg edges of which the brackets 13, 13 'are fastened. These brackets can be riveted or screwed into the two legs of the U-profile spar 14 and thus contribute to a torsional stability of the bed frame spar.
  • transverse connections 16, 16' allow for easy, guided lowering of the connecting axis 20 and the separate transverse strip caps 17, 17 'under pressure under the brackets 13, 13', the axis 20 immersed in the recess 34 of the inner U-profile leg and the hose receptacle 15 and the central spring element 11 are deformed to about half their overall height 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 elastic deformation of the central spring element 11 and the bridge elements 12, 12 ', the good lateral guidance (in the longitudinal direction) by the largely constant length 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.
  • Permanently deformation-elastic materials can be used for the bridge suspension repositories, such as rubber, vulcanized EPDM rubbers, as well as plastics such as polyurethane foams or SEBS (styrene-ethylene-butadiene-styrene).
  • SEBS polyurethane foams
  • SEBS polyurethane foams
  • SEBS polyurethane foams
  • a low deformation hysteresis and retentivity of the material should be aimed for.
  • the cross-bar caps integrated in the bridge elements 2, 2 ' these can possibly be made of somewhat harder (plastic) material and pass seamlessly into the elastic bridge 2, 2' and central spring elements 1, 21.
  • Such composite techniques are widely used today.
  • the separate end caps 17, 17 advantageously consist of harder, barely or slightly twistable (plastic) materials; if necessary, a sliding bush can be used to ensure the rotatability around the connecting axis 20.
  • the axis can be made of metal, aluminum, brass or steel or of torsion-resistant plastics with fiber inserts if necessary.
  • FIG. 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.

  • An undercut 24, 24 ' , 24' 'of the overlapping shoulder of the bridge elements makes turning easier.
  • FIG. 4b shows a top view of the arrangement of a flexible band 25 over approximately 90% of the length of the bed subframe member 4, lying on the roller bearings 29 and connected to a spiral spring 26 and 26 'as longitudinal expansion elements in the head and foot part of the frame.

Abstract

L'invention concerne un embout triflex de suspension en pont à trois points pour traverses de cadre inférieur de lit, caractérisé en ce qu'un élément central de suspension (1) pouvant être supporté par un appui (5) fixe ou mobile, est placé de façon centrale entre deux éléments élastiques en pont (2, 2'), qui peuvent être raccordés au cadre inférieur de lit (4) par des ÷illets de fixation (3, 3'). Des capuchons de traverses (7, 7') peuvent être intégrés dans la partie supérieure des éléments en pont (2, 2') et former un angle obtus (α) l'un par rapport à l'autre. Des raccordements transversaux (6, 6') entre les éléments en pont (2, 2') et l'élément central de suspension (1) ou l'élément central de suspension formé par des segments cintrés, assurent une course vers le haut guidée et une bonne stabilité latérale. Les ÷illets de fixation (9, 9') peuvent de façon avantageuse tourner autour des tourillons de fixation (3, 3'). Les éléments (1, 2, 2', 6, 6') sont constitués de matériaux élastiques déformables. L'utilisation d'éléments de renfort et de l'appui fixe (5) permet d'adapter l'embout de façon individuelle au poids et à la répartition du poids du corps reposant sur le lit. Selon l'invention, la course d'adaptation s'élève à au moins H/2 de la hauteur H de l'embout, si l'appui (5) est fixe, et peut même atteindre h ≈ H, si l'appui est mobile et si les ÷illets de fixation (9, 9') tournent autour des tourillons de fixation (3, 3'). Les raccordements transversaux (6, 6') coopérant avec les éléments en pont (2, 2'), ou la chambre à air d'un appui plan pneumatique élastique ou une bande flexible/élastique peuvent servir d'appui mobile, les deux derniers accouplant de façon interactive les embouts. La course d'adaptation importante et le cas échéant l'accouplement au moyen d'un appui mobile commun permettent d'obtenir un confort optimal en position allongée dorsale ou latérale.
