Description

(54) UPHOLSTERY ASSEMBLIES (71) We, DUNLOP LIMITED, a British Company of Dunlop House, Ryder Street St. James's, London S.W.1, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement: This invention relates to upholstery assemblies and especially to reinforced, laminated cushion or mattress assemblies for sitting or lying upon.
In one embodiment, the present invention provides a laminated cushion or mattress assembly comprising two or more layers of a resilient foam material and provided with one or more reinforcing means, each said reinforcing means being attached to and between adjacent layers and comprising a substantially planar cord-and-wire structure.
Preferably, each planar cord-and-wire structure, may comprise four or more parallel cords of plastios material or of twisted paper, the cords being intersected at an angle of about 900 by a plurality of parallel meaal wires. Particularly suitable cord-and-wire structures for use in the assemblies according to the present invention include those available from Pullmaflex International Limited under the Registered Trade Marks PULL MAFLEX and FLEX-OLATOR.
The reinforcing means may conveniently be attached to and between the foam layers by means of an adhesive.
At least one of the foam layers, preferably the layer constituting the surface for sitting or lying upon in the cushion or mattress assembly, may have a plurality of profiles on that surface of the said layer to be adjacent the reinforcing means.
The degree of resilience of the cushion or mattress assembly may be varied by using foams of different hardnesses for the foam layers and/or by using additional reinforcing means. For example, in an assembly co,mpris- ing four layers of foam material, reinforcing means may be attached to and between each adjacent pair of layers, so that three sets of reinforcing means will be incorporated in the finished assembly.
We have found that cushion or mattress assemblies according to the present invention provide improved support in a longitudinal direction whilst allowing a certain amount of movement in a transverse direction.
We have also found that the presence of a third or additional foam layer and/or of additional reinforcing means allows an applied load to be distributed over a relatively large area of the assembly, leading to an improvement in resilience.
The provision of profiles on that surface of a foam layer to be adjacent the reinforcing means ensures adequate ventilation within the assembly. This in turn avoids the build-up of condensation and the consequent deterioration of the foam and/or the reinforcing means.
The present invention will be described, merely by way of example, with reference to the accompanying drawings, in which: Figure 1 is a schematic perspective view (with parts cut away) of one mattress assembly according to the present invention; Figure 2 is a similar view of a mattress assembly according to a second embodiment of the present invention.
In Figure 1, a reinforced laminated mattress assembly comprises two foam blocks 1 and 2. To and between the blocks is attached, by means of an adhesive, a cord-and-wire reinforcing means 3.
In Figure 2, a reinforced laminated mattress assembly comprises three foam blocks 1, 2 and 3. To and between blocks 1 and 2 is attached, by means of an adhesive, a cordand-wire reinforcing means 4.
Layer 1 is provided with profiles 5 on the surface adjacent the reinforcing means.
We have found that mattress or cushion assemblies according to the present invention compare favourably with known up holstcry assemblies, particularly with regard to ease of construction, durability, silence in use, aesthetic appearance and cost.
WHAT WE CLAIM IS: 1. A laminated cushion or mattress assembly comprising two or more layers of a resilient foam material and provided with one or more reinforcing means, each said reinforcing means being attached to and between adjacent layers and comprising a substantially planar cord-and-wire structure.
2. An assembly according to Claim 1, in which the or each reinforcing means comprises four or more parallel cords of plastics material or of twisted paper, said cords being intersected at an angle of about 900 by a plurality of parallel metal wires.
3. An assembly according to either of the preceding claims, in which the or each reinforcing means is attached to and between the foam layers by means of an adhesive.
4. An assembly according to any one of the preceding claims, in which at least one of the foam layers has a plurality of profiles on that surface of the layer to be adjacent the reinforcing means.
5. A laminated cushion or mattress assembly, substantially as hereinbefore described with reference to and as illustrated in Figure 1 of the accompanying drawings.
6. A laminated cushion or mattress assembly, substantially as hereinbefore described, with reference to and as illustrated in Figure 2 of the accompanying drawings.
