Definitions

  • one aspect of the present invention is to provide an integral and composite, resilient cushion which is formed as a Single unit.
  • the cushion provided by the present invention can be produced rapidly and economically with a minimum of operations or labour in general; it is capable of retaining its shape and resiliency through repeated and severe use; it is attractive in appearance and of clean design; and it is comfortable.
  • FIG. 1 is a perspective view of certain parts of a cush ion which are used in the present invention
  • FIG. 1a is an enlarged, fragmentary view of one portion of FIG. 1 device, as indicated by the arrow A in FIG. 1;
  • FIG. 2 is an elevational view of a mold showing the cover in the raised position and the base in cross section and,
  • FIG. 3 is a perspective view showing a cushion made in accordance with the present invention a portion being broken away and shown in section for clarity.
  • a rigid frame which may be of any desired material, shape, or size.
  • Metal tubular or rod stock is particularly satisfactory for such a frame.
  • the frame 10 is preferably of that shape.
  • a resilient and generally fiat support 11 is provided within and attached to the rigid frame.
  • This resilient support may be made of any one of various materials, but natural or synthetic rubber is preferable because of its ability to provide uniform and lasting support across the entire area of the cushion.
  • the support 11 has a series of tongues 14 at spaced locations around its periphery.
  • a metal clip 13 is bonded in each tongue for reinforcing purposes and which forms a particularly strong union with its respective tongue.
  • the support 11 is secured under tension within the rigid frame 10 by attaching means 15 which take the form of double-ended hooks that extend at one end through amass Patented Sept. 28, 1965 the tongue and its associated clip and at the other end extend through an aperture 16 in the frame.
  • a two piece mold having a cover 17 and a base 18 having a cavity 18a of the desired shape.
  • the frame 10 and the attached support 11 as shown in FIG. 1 are firmly secured to the inside surface 17a of lid 17 in any suitable manner.
  • a sheet 19 of suitably pre-formed, pre-fused polyvinyl chloride is placed in the cavity 18:: and conforms to the size and shape thereof.
  • Polyether 29 is then poured into the cavity 18a and the cover 17 then closed over the base.
  • the polyether 20 is then allowed to foam up to completely fill the mold cavity, including flowing through holes 11a of the support and between and around the spaces between the frame support and attaching means.
  • the mold is then placed in a curing oven (not shown) to cure the polyether foam.
  • the curing time may vary depending on the required properties of the finished product, temperatures and other factors, but a time range of five to fifteen minutes at a temperature of about C. has been found to be satisfactory. In any event sufficient heat is applied to raise the temperature of the contents of the mold to cure the polyether, but this heat should be insufiicient to affect the pre-fused polyvinyl chloride sheet 19.
  • the polyether is caused to adhere tightly to the frame 10, support 11 and polyvinyl chloride sheet 19.
  • the completed cushion is removed from the mold as an integral and one-piece unit.
  • the base 18 of the mold is heated, and the polyvinyl chloride may then be sprayed into the mold cavity and gelled and cured by the heat. Then the rest of the above process is carried out as described.
  • the polyether may be poured into the mold after the polyvinyl chloride has gelled, but prior to curing thereof.
  • the polyvinyl chloride is then cured during or after the foaming of the polyether as above described.
  • An uncovered unitary seat may be made by the above process, in which case the polyvinyl chloride would not be present, either in sheet or sprayed form.
  • a seat having no polyvinyl chloride cover would, of course, require a cover and this may be of any known seat covering material.
  • a composite and integral, resilient cushion comprising a rigid frame having an open centre, a resilient support secured under tension in and to said frame, attaching means for attaching said support to said frame, and foamed and cured polyether which has been poured around said support and which when cooled forms a cushion and extends into the space between said frame and support and surrounds said attaching means and said resilient support and is firmly bonded to said support, said attaching means and frame.
  • a composite and integral, resilient cushion comprising a rigid frame having an open centre, a fiat sheet of perforated rubber having a plurality of tongues extending outwardly at spaced locations around its periphe ery, attaching means securing said tongues to said frame whereby said rubber is secured under tension in and to said frame, foamed and cured polyether which has been References Cited by the Examiner UNITED STATES PATENTS 2,532,713 12/50 Gottfried 297452 2,907,074 10/59 Rhodes 26745 2,976,577 3/61 Gould 264-45 3,084,980 4/63 Lawson 297-455 3,117,819 1/64 Kudriavetz 297452 FRANK B.
