Definitions

  • the present invention relates to foam pieces, for example, for filling a comfort item, and to comfort items having such filling.
  • Foam is typically either supplied as a single piece having the size and shape thought to be desirable or alternatively, it is shredded and supplied in a shape that allows a larger degree of compression thus making it a softer choice.
  • the predefined shape of a single piece of foam may become uncomfortable during the sleep period, while shredded foam will collapse over a longer period.
  • a foam piece for filling a comfort item comprising a body part and a plurality of foam arms having a first end and a second end, where the first end is attached to the body part, and the second end protrudes away from the body part, and a plurality of contour recesses between the foam arms.
  • foam pieces are supplied which are better at retaining elastic deformation characteristics than the foam solutions of the art by retaining at least some air between pieces in the uncompressed state.
  • a filling is obtained having good filling properties and adding air to the comfort item.
  • the distance between the body part and at least a part of the contour recess is smaller than the distance between the body part and the second end of the foam arms. Thereby the foam arms are present along the body parts.
  • the foam piece is planar.
  • the foam piece extends in three dimensions from the body part.
  • the foam piece may comprise at least one through-going hole or blind cavity.
  • the holes and/or cavities may be arranged according to any angle relative to the foam pieces, such as perpendicular to the plane of the planar piece or parallel to the plane, or even angular relative to the plane.
  • the contour recesses between the foam arms have a depth being longer than the length of the foam arms. Therefore, even if a foam arm enters a recess, the entire recess will not be filled, and air will still be present.
  • the contour recesses between the foam arms have a width being smaller than the width of the foam arms. Thereby, the foam arms cannot fit into the recesses ensuring that the air in the recesses is maintained.
  • the contour recesses between the foam arms have a width being wider than the width of the foam arms. Therefore, even if the arms enter the recesses, air is still present and further, the arm does not lock in the recess.
  • the various embodiments of the present invention further relates to a plurality of foam pieces to be used as filling for a comfort item, wherein the plurality of foam pieces comprises a plurality of foam pieces according to the above.
  • Such plurality of foam pieces would be suitable as filling for a comfort item and would ensure a filling material introducing air into the comfort item.
  • a comfort item comprising a first volume delimited by an outer boundary, where the first volume comprises a plurality of foam pieces.
  • the outer boundary further delimits at least one second volume, the second volume comprising a comfort filling.
  • comfort filling is meant down, feather, buckwheat, latex, foam including memory foam, micro beads, polyester fibre or other biological or synthetic material generally being elastically compressible.
  • the comfort filling may be water, whereby the water allows at least the second volume to change shape reversibly.
  • the outer boundary delimits at least two second volumes comprising a comfort filling, where the first volume is placed between the second volumes.
  • the user may turn over the comfort item and retain the softness of the comfort filling between the foam and the skin.
  • the comfort filling is chosen from a list of down, feathers and synthetic fibres.
  • comfort item is meant pillows, mattresses and duvets.
  • the outer boundary and divider sheet are most often made of cotton, wool or synthetic fibres.
  • it has at least two arms, at least three arms, at least four arms, at least five arms, at least six arms, at least seven arms or at least eight arms.
  • it has at most three arms, at most four arms, at most five arms, at most six arms, at most seven arms, or at most eight arms.
  • the foam pieces are made of any type of foam such as open-celled or closed-celled foam. In a preferable embodiment of the invention, the foam pieces are made of open-celled foam.
  • FIG. 1 illustrates different foam piece embodiments according to the invention.
  • FIG. 2 illustrates foam pieces used in different comfort items.
  • FIG. 1 illustrates a number of foam pieces 100 according to the invention.
  • the foam pieces 100 may take a variety of different shapes as illustrated by the embodiments shown in FIG. 1 .
  • Foam piece 100 A is a rectangular plus-shaped foam piece.
  • Foam piece 100 B is a substantially rectangular plus-shaped foam piece having rounded corners closest to the centre of the piece.
  • Foam piece 100 C is flower-shaped.
  • Foam piece 100 D comprises eight arms protruding from a centre. These arms are placed with equal radial distance between each other in the plane.
  • Foam piece 100 E is like 100 D having thinner arms.
  • Foam piece 100 F is star-shaped.
  • Each foam piece according to the invention has a body part 101 and a number of foam arms 102 extending away from the body part 101 . Between two neighbouring foam arms 102 , the foam piece forms a recess contour 103 , where the distance between the contour and the body part 101 is lower than between the outer edge of a foam arm 102 and the body part 101 .
  • the recess may be shaped by straight edges as in the embodiment 100 A, as a concave recess as in the embodiment 100 B, and as an angle between two diverging lines as in 100 C.
  • shredded foam is blown into for example pillows and duvets. These arbitrarily formed pieces of foam will eventually settle against each other in a way, where there is substantially no free air between the foam pieces. This corresponds to the pillow becoming compressed. Shaking, beating and washing the pillows may then be performed to disband the shredded foam. However, this only achieves moderate success of separation and expansion of the pillow.
  • the foam piece is star-shaped, has an uneven number of arms, is a sphere and/or is elongated.
  • Embodiments 100 G and 100 H are two variations of embodiment 100 A.
  • Embodiment 100 G is a planar foam piece, whereby the foam arms 102 all extend from the body part 101 in a single plane. Then, only the thickness of the piece protrudes in the third dimension. Thereby, foam pieces may easily be produced from foam sheets or rolls or other convenient planar foam shapes.
  • the arms of the foam piece extend from the centre in all three dimensions. Thereby, pockets of air are secured even better between foam pieces.
  • Three-dimensional foam pieces may also take the basic shape of 100 D but instead having arms distributed in three dimensions according to the same distribution of 45 degrees between neighbouring arms.
  • star-shaped foam piece 100 F may have any number of arms extending symmetrically in three dimensions, such as conveniently 4, 6, 8, 12 or 20.
  • the foam piece further comprises holes or cavities.
  • FIG. 2 illustrates various embodiments of comfort items according to the invention.
  • FIG. 2A illustrates a pillow 200 A according to the invention, with a first volume 202 and a multitude of foam pieces 100 filling up this first volume 202 .
  • FIG. 2B illustrates a pillow 200 B according to the invention, being a combination pillow, where a first volume is filled with foam pieces according to the invention, and where a second volume 203 is filled with another type of comfort fill, such as feathers, down or fibres.
  • the volumes are separated by divider sheets 204 . Thereby, the shape stability of foam is achieved in combination with other product features, such as the softness of down, feathers or fibre.
  • FIG. 2C illustrates a pillow 200 C according to the invention, much like embodiment 200 B in that it is a combination pillow.
  • 200 C comprises two second volumes filled with another type of filling such as down or feathers.
  • the pillow retains its comfort in both orientations, and the user may turn it over during use.
  • FIG. 2D illustrates a mattress according to the invention, the mattress being a combination mattress, where a first volume is filled with foam pieces according to the invention, and where a second volume 203 is filled with another type of filling, preferably feathers or down.
  • a first volume is filled with foam pieces according to the invention
  • a second volume 203 is filled with another type of filling, preferably feathers or down.
  • the recesses When a multitude of foam pieces according to the invention is placed together, the recesses then geometrically hinder the foam pieces from taking up the full space of the comfort item. Instead, air pockets among the foam pieces remain. These are then compressible by a user on use. Thereby, the total compression range remains greater for a longer period of time.
  • the foam pieces are not shredded, their edges are significantly smoother, whereby even if they settle into a somewhat clumped position, a shake of the comfort item will release the foam pieces much better than will be possible with shredded foam pieces which may easily fasten strongly together. In an embodiment of the invention, this allows the pillow not to experience fatigue like normal shredded foam-filled comfort items.
