Definitions

  • This invention relates to spring location means, and is particularly but not exclusively, concerned with coil springs as used in chairs and other seating or bed arrangements.
  • cushions that are supported on flexible means provide a more comfortable seating arrangement, as the flexible means provides a support and positional adaptability to a range of human body mass and sizes.
  • the ability to 'give' allows the cushion supporting the human form to mould itself better to different people than a cushion that is not supported on flexible means.
  • Cushions that are not supported by flexible means have the tendency to settle more than those that are supported on flexible means and have a shorter comfortable life span.
  • coil sprung units have been widely used that are an improvement on the foregoing support arrangements, but they too have their limitations.
  • Coil sprung units have been made in many configurations.
  • coil sprung units can provide a support unit which has independent support features.
  • a number of coil springs are attached to a chair or settee frame to provide the cushion support.
  • the top or end coils of the springs are limited in their independence by the mesh.
  • the mesh provides a layer or platform onto which the cushion is placed. This layer or platform is, in itself, usually covered in a cloth layer which may also be padded to provide an even surface on which the cushion can rest.
  • a 'frame' of strip steel or wire provides a boundary for the spring unit, so that the whole assembly can move vertically up and down, limited only by the metal latts to which the lower spring coil is attached.
  • latts being inflexible in nature, are attached for example, to a chair support frame by mechanical means such as a nail.
  • a latt usually at an intersection, is attached the lower coil of the spring by other means such as a rivet and, in turn, the upper coil is attached to a metal mesh by either winding the spring end coil into the woven metal mesh, or by clipping it into place with metal clips or rings.
  • the whole assembly being attached at its lower spring extent to the latt and support frame, is now provided with some independent movement of the individual spring within the limitations of the mesh flexibility.
  • This type of sprung unit has certain drawbacks. It is heavy, is made of metal, the mesh and support latts can corrode. It is time-consuming to manufacture and, therefore, costly to assemble and subsequently fit to such as a chair. Relative movement of the mesh, spring, securing rings and wire frame can be noisy; the woven metal mesh, being largely open on its surface, will allow fillings and padding to pass through the gaps which can bind the spring and afford less comfort to the user over time. There is the prospect that the latts will break with fatigue, and the spacing of the springs within the assembly is dictated by the intersection of the latts or position of the latts.
  • the object of the invention is to provide a spring support that avoids those disadvantages mentioned above in the employment of coil springs as the flexible support in chairs or other seating or bed arrangements.
  • an upholstery spring structure comprises a support sheet of a flexible substantially inelastic material, a number of spring location means secured in a required array over one surface of the support sheet, the spring location means each having an attachment for the securing of a respective spring, and whereby the springs extend from the support sheet at required spacings.
  • the spring location means may be a plate-like support member, with at least two attachment means strategically positioned in spaced arrangement on the plate-like member to hold an end turn of a coil spring to the plate-like support member.
  • the support member may be ring-like or other geometric shape with a free central area, suited to the shape of the end turn of the spring, and each attachment means may be at least two clip members attached respectively to the outer end and inner faces of the ring-like member.
  • the spring location means comprises a body of regular or irregular geometric shape, a support rib on the body inwardly spaced from the edge of the body, and at least two attachment means on the body in close proximity to the support rib, and whereby an end turn on a coil spring can be located against the support rib and held by the attached means.
  • the support rib preferably has a peripheral shape to correspond to the shape of the spring to be attached to it, i.e. circular for a circular spring, square for a square spring etc.
  • the body is preferably circular and may be a circular annulus, with the support rib located approximately centrally of the annulus and, for added strength, strengthening members may bridge opposite sides of the annulus.
  • a Y-shaped arrangement of strengthening members can be provided that can assist in the attachment of the location means to a sheet, but preferably a thin flange of sheet material is provided extending inwardly of the annulus, or a membrane is provided closing the annulus, by means of either of which the annulus can be secured, e.g. by welding to a support sheet.
  • each attachment means may be formed by three clip members, two to one side of the rib and one to the other, the one rib being positioned centrally of the other two, and the facing faces of the members may each be formed with a concave recess, such that with a spring wire inserted between three members, it snaps into the concave recesses and is firmly held by three-point contact.
  • two diametrical attachment means can be employed, it is preferred to have three or more attachment means at required locations around the body.
  • the support sheet may be formed from any suitable elastomeric material exhibiting high tensile strength, reasonable flexibility and low to non-existent elasticity.
  • the material may be a non-woven polymer such as polypropylene.
  • the circular or annular body of the location means is preferably formed from a compatible plastics material, able to be secured to the support sheet by welding, by a compatible adhesive, by rivets or other mechanical means.
  • the support sheet may have a length and width to suit a particular item of furniture, and the spring location means distributed over its area in a required array, or the support sheet may be a latt, with location means attached to it in spaced relationship, a number of such latts being combined, in, e.g. woven fashion, to extend over the area of an item of furniture where springs are required.
  • the latts may be of the same non-woven polymer but could be of any other suitable material, even metal.
  • a spring can be attached to each location means, and the sheet with its suspended springs loaded into a chair or other seating arrangement in relatively conventional manner.
  • a second support sheet or member or latts may be provided to which are attached the lower ends of the springs, with co-operating location means attached to the upper surface of the second support sheet.
  • the second support or latts can be of the same non-woven polymer as the first support or latts but, preferably, is of a stronger, less flexible grade of plastics material, or is a rigid support.
  • the invention facilitates the use of a variety of known forms of coil springs, to provide the level of comfort/firmness as may be required.
  • relatively conventional parallel, barrel, hourglass and cone springs can be employed.
  • parallel and barrel springs the diameters of the top and bottom coils may be the same, when one size of location means can be used attached to the upper and lower sheets.
  • cone springs two sizes of location means are required to accept the larger (upper) and smaller (lower) coil diameters.
  • Other embodiments are possible such as to have an array of parallel springs with springs of a larger diameter alternating with springs of a smaller diameter. Equally, the array can be of cone springs where adjacent springs are alternately disposed i.e., one with its larger diameter lowermost and the adjacent spring with its larger diameter uppermost.
  • one location means may be provided, with an outer member to accept the larger upper coil, and an inner member to accept the smaller lower coil.
  • Each upper and lower support sheet can be provided with a wire or strip frame.
  • Traditional mounting methods employing metal rings or clips can be used but, the location means may be provided with means of locating and securing the frame independent of spring position on the top sheet, to allow for inaccurate location of or intentional offset location of the locations means relative to the border frame, i.e. equi-spaced offset, near or far location and staggered.
  • the edges of the sheets can be folded over the frame and welded, to trap the frame within the material of the sheet.
  • an upper and a lower sheet, support plate or base each with spring location means can be provided, along with a centrally disposed sheet, on which location means are provided to both sides.
  • a first coil spring can be attached to the location means on one (upper) sheet, and to the location means on the central sheet to that side, and a second spring attached to the location mean to the opposite side of the central sheet, and to the co-operating location means on the lower sheet, support plate or base.
  • the location means can be all of one diameter to accept parallel or barrel springs, or the location means on the central sheet can be of a smaller diameter to allow the use of conical coil springs.
  • the location means provision can be made for it to be used with a range of spring wire diameters.
  • the snap fit clips located on the inner and outer annulus of the support member are provided with a channel large enough for the largest in the range of spring wires. When the largest wire is used, there is a positive location and no clearance left between the spring wire and the channel. In this configuration, there is no relative movement which could cause noise in the assembly.
  • On the location means there may be provided a section of moulding between the clip members of the attachment means which provides an upward force to the spring wire so that when a spring wire of the lowest diameter in the range is used, there is again interference provided to eliminate relative movement and, again, suppress the opportunity to produce noise.
  • the invention provides a number of advantages over conventional constructions. Thus, a clean unit is provided, where the top support does not allow the passage of debris. The unit is quiet during use, and a considerable range of spring configurations is easily accommodated, with the possible employment of a variety of different coil springs. The invention also permits the employment of less costly components and provides for lower assembly costs. Whilst primarily intended as a support for use in chairs or other seating arrangements, the invention also has potential in its application to mattresses for beds, or other forms of body supports.
  • a major disadvantage of modern mattress manufacture is in its highly automatic machinery where regular patterns of springs are held together in close proximity to each other.
  • the present invention would allow for totally independent spring positioning so that a more cushionable body support arrangement can be provided.
  • the present invention allows completely free placement of springs in such arrangements but goes further, to allow different spring diameters, barrel, parallel, hourglass and cone spring combinations, within the same mattress unit. It goes ever further in allowing the free location of the above spring and spring combinations within a foam lattice structure.
  • the major advantage of this arrangement would be to employ the spring-supported mattress in hospital and acute health medication, to alleviate the effects of bed sores and pressure points.
  • Existing methods of counteracting such conditions are to use very special and expensive polymer foam products which can support a body, but even out the reactive forces.
  • the present method provides the same support but, unlike the special foam, can be made with totally independent zones so that the reactive forces from the springs and/or foam lattice, are optional for each patient and each patients body structure.

  • the rib 3 In close proximity to each attachment means the rib 3 has a moulded section 7 extending away from the remainder of the rib, to serve as a means of providing a force on a last turn of a coil spring fitted to the clip members.
  • the circular annulus forming the body 2, and the support rib 3 can be of any larger or smaller diameter to suite a coil spring diameter to be attached to the location means, and the moulded section 7 allows different coil spring wire diameters to be accommodated, and ensure that the last turn of a coil spring is in tight engagement with the shaped inner faces 6, to stop the movement of the coil spring in situ and assist in suppressing noise as can be emitted by spring movement.
  • an internally disposed flange 8 can be provided on a larger annulus, or a membrane 9 can close the central area of a smaller annulus.
  • a single location means can be produced able to accept either a large of a smaller end coil of, e.g. a conical spring.
  • a construction as in Figure 2 can be located co-axially with a structure as in Figure 1 , and triangulated integral arms 10 provided to secure the two circular annular members together.
  • attachment arms 11 can be provided on, e.g. a location means intended for a corner of an upholstered spring structure, to allow positive attachment of it to side frame members of, e.g. a chair.
  • a number of spring location means 1 may be provided in spaced array over the surface of a flexible and relatively inelastic sheet 12.

Whilst annuli of the same diameter are illustrated, it will be understood that larger and smaller location means can be attached to the sheet in alternation.
  • an inelastic sheet 12 can be provided with location means 1 for coil springs attached in co-axial manner to opposite faces of that sheet, after the manner of connection of the location means discussed above.
  • an upper sheet with dependant springs can be provided the free ends of which attach to the location means to one side of the sheet 12, the free ends of co-operating springs extending upwardly from a lower sheet or base support being attached to the location means at the opposite side of the sheet.
  • conical springs can be provided with their coil of smallest diameter being attached to the location means centrally of the composite construction, but equally barrel or parallel coil springs can be employed.
