Definitions
- the invention relates to an elongate body of plastic foam having a covering layer on at least the flat sides, for example a mattress or a seat cushion for an article of seating furniture, wherein compression springs are arranged in the body oriented to the flat sides and pressure distributing means for distributing the forces exerted by the compression springs.
- a foam body is known from the German utility model 89.03.761.
- the foam body known from this utility model is provided with compression springs arranged in recesses in the body and pressure distributing means placed on either side thereof.
- These pressure distributing means take the form of quite stiff plates, the dimensions of which in peripheral direction correspond approximately with those of the foam body, and which distribute over the whole surface of the body the pressure forces exerted by the springs during use of the body.
- the pressure distributing plates are provided on their sides remote from the springs with a layer manufactured from a plastic foam or other soft material.
- a drawback to the foam body constructed in this manner is that, because of the stiffness of the pressure distributing plate, the form of the body does not adapt optimally to the form of the user sitting or lying on the body.
- the present invention therefore has for it object to provide a body of plastic foam as described in the preamble of claim 1 wherein this drawback is obviated.
- the pressure distributing means consist of separate plates placed on at least one of the end portions of at least one of the springs, the dimensions of each of which plates are greater transversely of the spring direction than those of the end portion of the associated spring.
- the springs are coil springs and each plate has a protruding, cylindrical portion enclosed by the spring.
- the coil springs are preferably of conical form.
- the invention further relates to a method for arranging springs and pressure distributing plates in a foam body wherewith a resilient foam body according to the invention can be manufactured in simple and economic manner.
- Each channel is preferably open at one end.
- each channel can also be open at two ends and, after arranging the channels and placing the springs with the plates, these ends can be closed off by a layer of plastic foam.
- An elongate body 1 manufactured from plastic foam, profiled on one side and forming a seat cushion for an item of seating furniture 2 (fig. 1) is provided with channels 3 arranged from the flat side at regular mutual intervals wherein compression springs 4 are placed which exert pressure forces when the body 1 is loaded.
- pressure distributing means are fitted on either side of springs 4.
- These pressure distributing means comprise at the bottom 6 a classical pressure distributing plate 7 made in one piece and at the top 5 separate pressure distributing dishes 8 placed on each spring 4, the dimensions of which are greater transversely of the spring direction than those of the top 5 of the associated spring 4.
- the pressure distributing dishes 8 comprise a flat portion 9 and a protruding, cylindrical portion 10 (fig. 2), which latter portion is close-fittingly enclosed by spring 4.
- the spring 4 can be provided with a pressure distributing dish 8 on one or both ends. (In the latter case the pressure distributing plate 7 shown in fig. 1 is of course dispensed with).
- the spring 4 with pressure distributing dishes 8 can likewise be applied in a combination body 11 assembled from two flat foam bodies 1, 1 (fig. 3). Both the bodies 1, 1 provided with channels 3 arranged in one flat side are in that case placed onto one another such that the channels 3, 3 lie mutually connecting.
- the channel 3 connects both flat sides of foam body 1 and the dishes 8, 8 distribute the force exerted by springs 4 into the resilient layers 12, 12 manufactured from a plastic foam or other soft mate rial and arranged on either side of body 1.
- the form of the pressure distributing means according to the invention makes it possible to produce the foam body in simpler manner than has been possible up to the present. Because two pressure distributing plates and soft layers covering the pressure distributing plates do not have to be arranged on either side of the compression springs and extending over the entire periphery of the foam body it is possible in the production of a foam body according to the invention to manufacture the foam body from one piece, to then provide it on one side with channels wherein springs with pressure distributing dishes are placed and to finally close off the channels.
