' MATTRESS STRUCTURE Filed sept. so, 1955 o j ,t .35 56,0111 J Jv), i :E: 2 i175/ INVENTOR.

United States Patent C MATTRESS STRUCTURE Max Koenigsberg, Highland Park, Ill., assignur to The Englander Company, Inc., Chicago, lill., a corporation ofiDelaware Application September. 30, 1 9,55,.Serial'No. 537,730 3'Clams. (Cl. 5-345) The present invention relates toa novel mattress, and more particularly to a novel foam rubber mattress structure.

Foam rubber mattresses heretofore; commercially avail able have usually consisted ofa single pad of foam rubber covered by a suitable fabric or ticking,k In order to provide such a mattress with the desired softness and luxurious feel, the rubber pad isgmade-relatively thick. However, as the thickness of the foam rubber` pad is increased, thegpad becomes'laterally unstable so that it may q uiver in a jelly-like'manner.

It is -an important object of'the present invention to provide a novel foam rubber mattress construction which is sufliciently thick so that the desired softness and luxurious feel is obtained and which is constructed so as to substantially reduce the undesirable lateral instability or jelly-like characteristics of relatively thick foam rubber mattresses heretofore proposed.

A more specific object of the present invention is to provide a novel foam rubber mattress structure -of the above described type which is formed so as to restrain peripheral and internal portions thereof against spreadinglaterally or outwardly under the weight of a person lying on the mattress so that the mattress is firmer and more stable while still having the desired softness.

Other objects and advantages of the present invention will become apparent from the following description and the accompanying drawings wherein:

Fig. l is a perspective view of a mattress structure embodying the principles of the present invention;

Fig..2 is an exploded perspective view on a reduced scale of the internal elements of the novel mattress structure;

Fig. 3 is an enlarged fragmentary sectional View taken along line 3 3 in Fig. l; and

Fig. 4 is an enlarged fragmentary elevational View of a corner portion of the novel mattress structure.

Referring now more specifically to the drawings wherein like parts are designated by the same numerals throughout the various figures, a mattress structure l@ embodying the principles of the present invention includes a pair of

pads

12 and 14 formed from foam rubber or the like. The foam rubber pads may be formed in any known manner and may be provided with

air pockets

16 and 18, if desired. The combined thickness of the pads l2 and 14 may be varied but should be sufficient to provide the mattress with the desired softness and luxurious feel.

In accordance with the present invention the lateral stability or firmness of the interior portions of the mattress is substantially improved by providing a sheet 2t) between the

pads

12 and 14. The sheet 20 is formed from any suitable flexible material or fabric which is relatively unstretchable as compared with the foam rub ber pads, and the sheet is adhesively secured as indicated at 22 and 24 to the inner surfaces of the pads l2 and 14 so that the pads and the sheet are combined as a unit. The relatively unstretchable sheet serves to restrain the ice interior surfaces of the lpads and the portionsiof. the;pads adjacent the .interior surfaces againstlateral expansion while at the same time, the-exiblelsheetdoes; noti' unduly impair the softness of the pads.

The foam rubber padsare covered with fabricjpanels or ticking which provide the mattress-withk the;desired pleasing appearance and also serves to connetheperipheral surfaces of the p ad. More particularly,the;mattr,ess cover comprisestopand `bottom fabric panels 26andl28, and a pair of fabricstrips ,30.and 32 wh,ichextendentirely around the edge of the mattress. As-showninFig-.; 3, the peripheral ledge of. thepanel 2.6;substantially abuis the upper edge of theepanel'30, and, abindingtstrip 3,4-.is placed over these edges and the-.strip and edgesfarefsewn together by stitches. 36. Breferably, 'the edges,n of,r the panels are folded.reversely asl shown, andrthezstitches are directed through the double,thicknesses:,providedeby-the folds so asito reduce anypossibility ofthe panels becoming torn. It should be noted that,thefstitches,36exten'd throughthe upper,peripheral-,corner oftthegpad 12i-sosthat the fabric panels areheld illlxedrelationshipwith respectjto the foamrubber-pad. The;bo ttom;pane1.28tis connected withv the edgpanel or! 'strip 32 along al seam which includes .a binding stripV B and; stitches 40 which are formed vand positioned inA the; same mannen as.- the binding Ystrip Sland ,stitches .Sndcscribedi above..

The fabricpanel` 2li., which,` is. disposedl betweenr-.aud adhesively secured to the

foam rubber pads

12 and 14 has its peripheral edge secured to adjacent edges of the strips or panels Sti and 32. As shown in Figs. 3 and 4, a binding strip 42 is placed over the adjacent edges of the

strips

30 and 32, which edges are reversely folded to reduce any possibility of tearing. The peripheral edge of the panel 20 extends between the folded edges of the

panels

30 and 32, which edges and the binding strip 42 are secured together by stitches 44. With this structure, the panel 20 serves to prevent'the

panels

30 and 32 from stretching outwardly when a load is on the mattress, and the

panels

30 and 32, in turn, retain the foam rubber pads against undue lateral expansion.

From the above description, it is seen that the present invention has provided a foam rubber mattress structure which may be easily and economically fabricated so as to have suihcient depth to provide the desired softness and luxurious feel without having undesirable lateral instability. More specifically, it is seen that the present invention has provided a novel mattress structure cornprising a plurality of foam rubber pads confined by and secured to flexible but relatively unstretchable fabric panels in the manner which substantially improves the lateral stability of the foam rubber pads without unduly impairing the desired softness or feel of the mattress.

While the preferred embodiment of the present invention has been shown and described herein, it is obvious that many structural details may be changed without departing from the spirit and scope of the appended claims.

The invention is claimed as follows:

l. A mattress structure comprising a cushion unit including a plurality -of superposed pads of foam rubber and the like each having a plurality of air pockets having open ends at a surface thereof facing an adjacent surface of another pad, and a flexible relatively unstretchable fabric sheet disposed between and adhesively secured substantially to entire adjacent surfaces of adjacent pads around the open ends of the air pockets to increase lateral stability of the pads, and cover means including side portions overlying opposite sides of said unit and an edge portion surrounding a peripheral edge of said unit, said fabric sheet having its peripheral edge stitched to said cover means edge portion between said side portions for restraining said edge portion and peripheral edges of said pads against lateral expansion when a load is placed on Patented Nov. 111958 3` the mattress, and stitch means connecting adjacent margins of said side portions and said edge portion and also extending through adjacent outer peripheral corner pertions of opposite outermost pads for retaining the cover means and the pad in substantially Xed relationship and for further restraining lateral expansion of the pads.
