Definitions

  • This invention relates to support systems for mattresses or cushions in beds, chairs, sofas, settees, stretchers and other body support appliances. Such support systems will be referred to as systems "of the kind defined”.
  • the invention is particularly applicable to support systems of the kind defined in which a mattress or cushion rests on slats extending between supporting air springs.
  • My European Patent Application publication No. 0.0 38155 disclose mattress support systems of this kind in which the air springs are in the form of long inflatable tubes on which the ends of mattress supporting slats are rested.
  • Such beds have been successful but one problem has been the tendency for the slats to move on the tubes and the consequent need to provide some holding means which will not interfere with the flexure of the springs or the slats and which is not unduly complex and expensive.
  • the present invention enables economical manufacture of air springs fitted with appropriate slat restraining means.
  • DE-B-2621803 discloses a bed having spaced, longitudinally extending rigid members each accommodating a closed elongate resilient tube which is filled with a medium capable of flowing and pressurised to meet the requirements of the person using the bed.
  • the upper surface of each tube has a plurality of spaced pockets vulcanised thereto with the pockets of one tube all facing towards the pockets of the other tube.
  • the body support surface of the bed is formed by a plurality of transversely . extending, laminated slats arranged parallel to each other with their ends fixedly mounted in the tube pockets.
  • a support system for mattresses in beds or the like comprising spaced elongate air springs formed by inflatable tubular bladders each provided with a series of longitudinal spaced pockets having open mouths, a purality of transversely extending slats having their respective ends accommodated in the pockets of said air springs characterised in that stabiliser means are provided interconnecting said air springs to provide lateral stability of the support system, the stabiliser means comprising a transversely-extending member accommodating, without clearance, the air springs.
  • the pockets are formed in a tangential flap connected to the tubular bladder along a longitudinal connection line at the surface of the tubular bladder such that the open mouths of the pockets are spaced along a longitudinal edge of the flap.
  • the invention also provides a method of making an air spring, comprising forming two tubes of heat weldable sheet plastics material with a longitudinal heat welded seam and so as to leave a longitudinal strip of said sheet material projecting beyond the seam exteriorly of the tube, and folding and welding said strip of material to form a tangential flap with longitudinally spaced pockets having open mouths spaced along a longitudinal edge of the flap, so as to form two air springs, interconnecting the two air springs by means of a plurality of transversely-extending slats having their respective ends accommodated in the pockets, and providing stabiliser means interconnecting said air springs to provide lateral stability of the support system, the stabiliser means comprising a transversely-extending member accommodating, without clearance, the air springs.
  • FIG. 1 illustrates a mattress support system for a bed comprising a series of parallel wooden slates 11 extending between a pair of elongate inflatable air springs 12.
  • the air springs 12 can be mounted in any convenient frame (not shown).
  • Each air spring 12 comprises an elongate tube 13 formed with closed ends 14 and with a tangential flap 15 which is connected to the tube along a longitudinal connection line 16 at the surface of the tube and has a series of longitudinally spaced pockets 17 with open mouths 18 located along one longitudinal edge of the flap to receive the respective ends of the slats 11.
  • Each tubular bladder is formed of heat welded sheet plastics material, the tube being closed by a longitudinal welded seam defining the connection line 16, and the flap is formed by a continuation of the sheet material of the bladder which is folded and welded to form the pockets so that the flap is integrally connected with the bladder at the seam.
  • the ends of the tubes are closed by heat welds 19 and one end of each tube is fitted with an inflation valve 21.
  • the air springs 12 can be mounted in any convenient frame (not shown) which is usually of 'U'-shaped cross-section for at least a portion of its length.
  • the support system shown in Figure 1 incorporates a stabiliser arrangement as shown in Figures 14to 16 and now to be described.
  • the stabiliser comprises an open-ended, flattened tubular member 55 of sheet plastics material similar to the tubular bladders 13.
  • the member 55 is of a length slightly greater than the overall width of the bed and is provided with spaced apertures 56 whose axes correspond, respectively, with the axes of the tubular bladders 13.
  • the diameter of the apertures 56 is slightly less than the diameter of the tubes 13 to provide a gripping action when the stabiliser is mounted on the tubes.
  • One edge 58 of the tubular member 55 has a seam 57 formed by heat welding extending parallel to, but spaced slightly from the edge 58 to provide an elongate chamber 59 extending the length of the member.
  • a predetermined slat 11a is removed from the bed and a rod 60 is accommodated in the chamber 59.
  • the stabiliser is then positioned on the bed after removing slats 11 as necessary, by passing the tubular bladders 13, respectively, through the apertures 56 in the tubular member 55 until it reaches the location at which the predetermined slat 11a has been removed.
  • the slat 11a is then passed into the upper portion of the tubular member 55 (see Figure 14) and its ends, respectively re-inserted into the pockets 17 formed in the tubular bladders 13 so that the cross-section of the stabiliser adopts a triangular configuration (see Figure 16).
  • the stabilisers may take other forms.
  • the lower rod 60 may be replaced by a slat 11 similar to the slat forming the support surface, In this arrangement, when positioned on the tubular bladders 13, the stabiliser cross-section is of rectangular configuration.
  • the upper slat 11 may be replaced by a rod similar to the lower rod 60.
  • the stabiliser is positioned between adjacent slat 11.
  • the stabiliser comprises a single membrane of plastics material having rod-accommodating chambers formed along its upper and lower edges.
  • Figure 5 shows a heat welding apparatus comprising a sliding table 22 slidable along a bench 23 beneath a vertically movable welding head 24 fitted with an elongate heat welding bar 25.
  • a sheet 26 of heat weldable plastics material is wrapped around a backing bar 27 on table 22 to form a tube and this tube is closed by heat welding a longitudinal seam by bringing the welding head downwardly so that the overlapping layers of material between the welding bar 25 and the backing bar 27 are welded together.
  • This stop in the process is shown in cross-section by Figure 7.
  • a wide strip of the plastics material is allowed to project beyond the heat welded longitudinal seam exteriorly of the tube.
  • This strip is subsequently folded and welded to form the pocketed flap. More specifically, the strip is double folded in the manner which will be apparent from Figure 3.
  • the sheet material extends from the seam to a first longitudinal side edge 31 of the flap where it is folded back at 32 to extend to the second longitudinal side edge 33 of the flap and it is there folded at 34 to extend to a free edge 35 at the first-side edge 31.
  • the thus folded strip is then laid flat on the table 22 as illustrated in Figure 8 for welding of the pockets, In order to weld the pockets, the welding bar 25 is replaced by the specially shaped welding bar 36 illustrated in Figure 6.
  • This bar is formed with U-shaped projections 37 at intervals along its length and when the welding head is brought downwards, these projection weld the three layers of the sheet material between the longitudinal seam and the side edge 31 of the flap together to define the pockets. More particularly, the sliding bar produces U-shaped heat welds having limbs 38 sealing the edge of the flap between the pocket mouths and legs 39 extending from one another.
  • the pockets are not completely sealed form one another since the welds do not extend across the full width of the flap but they do serve effectively as individual pockets to hold the slats apart.
  • the flap can move aboutthe longitudinal seam and can flex so as to permit free flexure of the slats while the pockets provide the necessary restraints against shifting of slats.
  • the ends of the tube can be closed by simple heat welding and inflation valves also heat welded in place to complete the air spring.
  • Figures 9 and 12 illustrate an alterative construction in which a pocketed flap is formed by a single fold and welding operation rather than by double folding as described above.
  • the tube is again formed by producing a longitudinal seam with a strip of the plastics material projecting beyond the seam.
  • the strip is folded with a single fold at 41 so as to form a flap having only two layers of material and extending only to one side of the longitudinal seam.
  • the U-shaped welds 42 defining pockets may be produced by gripping the material to be welded between the welding bar 36 and the backing bar 27.
  • FIGs 10 and 13 illustrate the manner in which a flap may be formed so as to have pockets along both of its longitudinal edges.
  • An air spring with such a double pocketed flap may be used to support the ends of two adjacent sets of mattress support slats, either as a central support spring in a double bed or, in some cases, as an additional central support in a single bed.
  • the flap 43 is initially formed in the same manner as the flap 15 of the construction illustrated in Figures 1 to 4 and the flap thus has a series of pockets 44 along one edge corresponding to the pockets 17 of the previous construction.
  • an additional series of pockets 45 is formed along the other side of the flap by trimming off the folded edge of the flap at the line 46 and applying additional 'U'-shaped welds 47.
  • Figure 11 shows an alternative manner of producing a flap with pockets along both sides.
  • a separate sheet strip 51 of weldable material is laid over the folded strip 52 and the two welded together at the seam line and around the pockets.
  • the pockets could be formed by welding a strip of material to the surface of the tubular bladder so that the pockets are formed directly at the exterior surface of the tube.
  • the pocket forming strip could be connected integrally with the tube and be folded back against the tube after the longitudinal seam has been welded or it could be a separate strip welded to the tube.
  • the pockets are formed in a tangential flap to avoid direct contact between the slats and the wall of the inflatable tube and the welding of the pockets directly to the tube wall entails the risk of pinholes and localized thinning of the tube wall which could give rise to blowouts.
  • the alternatives are feasible.
