Definitions

  • cu mo FF 6 e n g spring upholstery assembly comprised encapsulated in a shell of flexible foam terconnected by an integral web of b has a thickness less than the axial permitting independent movement d a l d m r m .m w a V.
  • This invention relates to a spring upholstery assembly suitable for use in bedding, chair seats and backs, and like articles of furniture.
  • Prior art spring upholstery assemblies as used, for example, by the bedding industry in the production of mattresses have included interconnected coil spring assemblies wherein adjacent springs have been connected adjacent their ends and/or intermediate thereof by stringers or hog rings and have also included what have become known as pocketed springs.
  • Some pocketed spring assemblies have been characterized in that adjacent springs in the assembly have not usually been connected together at their ends or intermediate thereof by the conventional hog rings but have only been interconnected by interstitching between adjacent fabric pockets within which the individual springs are located.
  • mattresses constructed of a foamed elastomeric material some of which have been provided with metal coil springs totally embedded therein.
  • a pocketed spring assembly generally seeks to provide a structure wherein any one spring, or group of adjacent springs, may be deformed into compression without unduly disturbing adjacent uncompressed springs of the assembly.
  • the inherent spring characteristics may, in fact, be modified by the encapsulating foamed elastomer by selecting a foam of appropriate density.
  • a spring upholstery assembly including a plurality of coil springs located in side-by-side relationship, each of which is encapsulated in a foamed elastomeric material and wherein each spring proper is interconnected to an adjacent spring by the said encapsulating material at positions intermediate the ends of the springs, the said ends, at least, of each spring being free for independent movement relative to the ends of adjacent springs.
  • Each encapsulated spring is preferably of barrel-shaped configuration, the largest diameter parts of which are interconnected to adjacent encapsulated springs and it is also preferred that the interior of each encapsulated spring is cored whereby each spring may be freely compressed without any significant interference from the encapsulating material. Furthermore, it is preferred that the complete encapsulated spring assembly be cast as a unit from a foam plastic material such as flexible urethane.
  • FIG. 1 is a partly sectioned top perspective view of a mattress incorporating the spring upholstery assembly of the invention
  • HO. 2 is a top plan view, partly in section, of a row of encapsulated springs of the instant spring assembly, and
  • FIG. 3 is a side elevation, partly in section, of a part of the instant spring assembly.
  • a spring upholstery assembly in accordance with the invention may take the form of the mattress M illustrated herein in the accompanying drawings wherein the desired resilience and support is primarily imparted to the mattress by a plurality of side-by-side metal coil springs 10, each encapsulated in a resilient elastomeric material 12 forming a pocket P for the spring 10 and the springs being resiliently interconnected together at 14 in such manner as to support one another and whereby each spring 10 may act substantially independently of its immediate neighbors.
  • the elastomeric material 12 which is preferably a flexible foamed urethane, may be of sufficiently low density that, despite the encapsulation of the springs 10, it need not contribute significantly to the actual spring action. That is to say, the inherent characteristics of the springs 10 may be substantially unimpaired by the encapsulating material 12 but, at the same time, since it is expedient that the resilient interconnection 14 is comprised of a web of the encapsulating material integral therewith, it should be realized that the said material must be of sufficient density to maintain the springs 10 in side-by-side relation in their desired upstanding position relative to one another.
  • the springs 10 illustrated herein may be chosen to be heavy-duty springs (as represented at 10a in FIG. 3) whereby the resilience of each pocketed spring is stiffened providing a firmer support as compared with the lighter gauge springs illustrated at 10.
  • each spring acts independently of its neighbors in the general manner of a pocketed spring by virtue of the fact that adjacent springs 10 are only interconnected intermediate their ends as at 14 whereby free independent movement of any one spring relative to another is procured.
  • Such an independent action as aforesaid is obtained, in the embodiment illustrated herein, by encapsulating each spring in a substantially barrel-shaped cored enclosure, the largest diameter part of which is integrally connected to the encapsulating material of the adjacent springs by the aforesaid web connection 14.
  • adjacent pockets P are interconnected only at their central portions by the web 14; there being no further interconnection such as by hog rings or the like between the springs proper 10.
  • the web interconnection 14 has a length which is approximately equal to one-third of the overall axial length of each pocket P. However, should it be desired to vary the overall characteristics of the spring assembly, it may be desired to vary the length of the web 14 between certain limits as illustrated diagrammatically herein in FIG. 3 by full and dotted outline of the web 14. It should also be noted herein that the thickness of the encapsulating material 12 around adjacent springs 10 combined with the barrel-shaped configuration of each pocket P enables the springs proper l0 to be spaced a finite distance apart from one another.
  • Such an arrangement precludes the possibility of adjacent springs from coming into contact with one another under compression whereby the possibility of inadvertent interlocking between adjacent springs 10 is obviated; such an arrangement also contributing in some part to an effective soundproofing of the overall spring assembly.
  • each pocket P is fully cored from one end to the other as will be clearly seen from FIGS. 2 and 3 of the drawings.
  • Such a construction further enables compression of each spring 10 without significant contribution to the spring action from the encapsulating material 12 since said material is able to be compressed outwardly on both sides of the spring convolutions as the spring 10 is compressed and the convolutions brought closer together. Since it is desired that each spring 10 be fully supported by the encapsulating material 12, it is expedient that the said spring 10 in each pocket P be completely invested by the material 12; that is to say, the material should enter between the spring convolutions and fully encapsulate them both radially inwardly and outwardly thereof.
  • the mattress M would normally be completed by the provision of a firm edging and ticking cover and also top and bottom pads between the ends of the pockets P and the cover.
  • the aforesaid firm edging may be cast integrally with the composite spring assembly and formed of a foam material which is of a somewhat higher density than the encapsulating material 12 and consequently more rigid to provide firm edge support to the mattress M.
  • the instant construction being comprised of a plurality of interconnected pockets P, lends itself to the casting of a variable density encapsulating material 12 throughout the spring assembly as a whole since the mould for each pocket P would be of substantially cup-shaped configuration initially retaining the casting material therein without substantial flow to adjacent cup moulds prior to the actual foaming step.
  • a further advantage of the composite spring upholstery assembly according to the instant invention is that, since the only interconnection between adjacent springs 10 is by means of the resilient web connection 14, the assembly as a whole may be flexible greatly facilitating its ready transportation from place to place and also facilitating its storage in a flexed condition such as may be required, for example, in a folding bed assembly.
  • top and/or bottom pads may be provided integral with the spring upholstery assembly; such pads being cast of a similar foamed elastomeric material to the encapsulating material 12.
  • Such integral pads need not detract from the independent spring action contemplated by the invention since the pads may be of an extremely low density foam and readily stretchable so that only localized deformation thereof would occur when any one or a localized group of the pockets P was depressed.
  • a spring upholstery assembly including a plurality of helical upholstery springs assembled in erect side-by-side spaced-apart relation with one another; a resilient web integrally interconnecting said springs and holding them in said assembly, the web thickness being less than the axial heights of the springs whereby portions of said springs project through said web; and resilient investment of the said projecting spring portions merging integrally with said web, said invested projecting spring portions being hollow over at least a part thereof; the resilience of said investment being insufficient to prevent compression of said projecting spring portions independently of one another under normal load but being sufficient nevertheless to restrict deflection thereof out of the erect sideby-side relation aforesaid.
  • each web interconnection 14 may extend continuously through the interior of the encapsulated springs which it joins together. Such an arrangement will provide an opposed pair of hollow interior cavities at the respective ends of each spring without, of course, detracting from the independent characteristics of each spring in the assembly as hereinbefore described.
  • a spring upholstery assembly including:
  • said invested projecting spring ends being hollow over at least a part thereof; the resilience of said investment being insufficient to prevent compression of said projecting spring ends independently of one another under normal load but being sufficient nevertheless to restrict deflection thereof out of the erect side-by-side relation aforesaid under said normal load.
  • each respective spring in the form of a generally cylindrical hollow shell extending axially of at least a part of said spring.
  • said investment extends over the complete axial dimension of each respective spring.
  • said web interconnects the said springs intermediate their ends.
  • each spring has an exterior configuration of generally barrel-shaped form tapering from the ends to a central zone thereof and said web interconnects said central zone, at least, of adjacent springs.
  • said web and investment are formed of a material having a resilience sufficient to modify the inherent characteristics of the springs during compressive movement thereof under load.
  • said material comprising said web and investment is a flexible foam plastic.
  • said web extends continuously through the said assembly of 5 springs providing an opposed pair of hollow interior cavities at the respective ends of each spring.
