Definitions

  • the present invention aims to obviate the above mentioned disadvantages whereby a novel combinationof an innerspring mattress together with a sheet of resilient foam material is utilized.
  • IIt is another object to provide for a mattress combining the advantages of the innerspring mattress with those of the foam mattress type.
  • FIG. l is a perspective view of a mattress embodying the invention
  • FIG. 2 is an enlarged part-sectional view showing the fixing of the intermediate layer, as is shown in FIG. 1,
  • FIG. 3n is a lperspective view yof a mattress iilling machine
  • FIG. 4 is a cross-sectional view tot the mattress showing the overlapping edges of the plastic foam sheet prior to bending by side-'walls of the iilling machine
  • FIG. 5 is a cross-sectional view of the mattress in its compressed iorm prior to tiilling into its ticking
  • yFiG. 6 is .an enlarged cross-sectional view of ⁇ a mattress after having been iilled into its ticking
  • FIG. 7 is an enlarged part-sectional yView of It-he mattress with modification embodying the invention.
  • the mattress :there illustrated comprises spring frame 3 and springs 1, together form- ICC ing the innerspring mattress structure of known construction, on iboth sides of which a thin intermediate layer 2 of rubberized iiibrous material, such as animal hair, coi-r iiber, palm iiber, sisal iiber is positioned which is turther covered with a llayer ⁇ 5, 5 of resilient foam material, such as plastic lfoam.
  • 'Iihe width of the overlapping edges of plastic iOam sheet 5a' is substantially equal on all sides.
  • the :angular :slot provided at each corner of the ⁇ foam sheet will form after bending the respective overlapping edges an even corner of the mattress.
  • the mattress filling :machine 6 in IFIG. 3 is used to complete the fiilling operation of the mattress -by compressing :and filling said mattress into ⁇ its ticking 15.
  • FIG. 3 of known type having parallel folding side walls together with locking devices being actuated by lever 3, a rotatable press cover 1i) comprising counter weight 16 for balancing said cover, driving mechanism (not shown) for the actuation of filling spoon 11, the shape of which is suited to the size of the mattress and a locking device 1S and 17 for keeping press cover 10 in position during the lling operation.
  • the opened side walls 7 of the lling machine 5 form a trough-like space into which the mattress can be easily inserted.
  • the overlapping edges of lower plastic foam sheet 5 will be bent into position and simultaneously the overlapping edges of upper plastic foam sheet 5 are bent manually in direction of arrow A to hold in position said edges by closed side walls 7, as shown in FIG. 3.
  • the rear end of the overlapping edges facing the filling spoon 11 is eiected in the same manner as the sides by manually bending said edges in contact with the iilling spoon 11.
  • gate 14 Before closing press cover iii, gate 14 is raised to the height ot the mattress to which gate the mattress is advanced and thereby the front overlapping edges of the plastic foam sheet are bent in position in similar manner as the side edges shown in FIG. 5. After pulling down press cover 10, which is easily shut by means of a handwheel 21, in FIG. 3, gate 14 is lowered to give free way for the advancing mattress which is moved forward by filling spoon 11. Before commencing the actual filling a ready sewn ticking is pulled over the front end of closed press cover l and bottom guide walls 9, as shown in FIG. 5.
  • a work-bench 19 is provided for accepting the advancing and completely filled mattress. After the filling operation the rear end of the mattress is sewn together thereby maintaining the bent-in edges in their intended position,
  • FIG. 6 is a cross-sectional view of an innerspring mattress with plastic foam covering according to the invention showing the respective layers in position as described above.
  • the height chosen for the innerspring structure will be in accordance with the required depth of the bed, which in most cases is 16 cm.
  • the rubberized intermediate layer 2 covering innerspring structure may have a thickness of 3 4 providing a sufiicient overall strength for evenly distributing the adjacently acting individual spring forces of the innerspring structure.
  • the metal frame and the continuously wound coil springs may have an anti-rust coating to maintain a clean interior and elasticity of the mattress. Since the individual spring forces have been evenly distributed by intermediate layer 2, the covering plastic foam sheets, 5, 5 may have a reduced thickness in the range of -30 mm.
  • the intermediate layer 2 preferably may have a weight of 450-500 g./m.2. If this weight is increased, the result will be a mattress with higher stiffness and if it is reduced, a mattress with less stiffness will result.
  • the layer 12 provided for the easy conveying of mattress into its ticking may have a thickness of 1 mm. or less. It may be omitted, if the outer surface of resilient foam material 5 is provided i.e. with an impregnated layer of antifriction nature for the smooth sliding of said mattress.
  • the width of the overlapping part of the plastic foam sheet 5 is chosen in such a manner that after bending the top and bottom foam layer, there is a gap d provided all around the sides of the mattress, which gap further means a space in which the up and down movement of the plastic foam cover edge can take place without any jamming or clamping by springs 1 of the innerspring structure.
  • FIG. 7 there is shown in part-section an innerspirng mattress with plastic foam cover being identical with that of FIG. 6 and in addition showing ticking 15a into which the mattress is compressed and filled in the manner as described and by retaining the original ticking 15 which in this arrangement is made to be easily changeable for replacement or for cleaning.
  • This embodiment as shown in FlG. 7 is particularly advantageous for medical purposes whereby the mattress can be used on both sides which is hygenic in use.
  • the outer ticking 15 may be pulled off, and the inner ticking 15a together with ⁇ the innerspring structure may be put into a disinfectant bath provided the metal parts are made of rust-proof material or have an anti-rust coating.
  • the material for the inner cover ticking 15a may be of nettle fiber and the material for the outer ticking 15 may be of any durable textile, preferably being of reinforced cotton nature.
  • a reversible, long-life innerspring mattress having goed form retention and a selected degree of softness, said mattress comprising,
  • an interconnected coil spring assembly having an outer surface, a lower surface and a continuous outer side edge
  • an upper and lower fibrous material layer covering said upper and lower surfaces respectively and each having marginal portions bent over and attached to said coil spring assembly
  • an upper and lower resilient, substantially planar foam material layer covering said upper and lower fibrous material layers respectively and each having a free peripheral portion thereof extending beyond said outer side edge of the mattress, said peripheral portion of said upper foam layer being overturned toward said lower foam layer at said side edge and said peripheral portion of said lower foam layer being overturned toward said upper foam layer at said side edge with said overturned portions of said upper and lower foam layers defining ends spaced from and substantially facing each other
  • said foam layers having corners defining angular slots therein positioned adjacent corners provided by said assembly
