solaimls. (oit-'351) f This invention relates to a mattress construction.
The invention has in view a mattress con- ,l
struction including a flexible resilient upper body extending continuously throughout the area of the mattress which affords a comfortable and. resilient support vand which is resiliently Asupported by a resilientinnerspring unit. A
Another object of the inventionis to -provide amattress construction which takesthe place of `andaccomplishes the results obtained by the usual combination ofinnerspring mattress and boxspring, bed or open coil springs andthe n like.
Another object `of the invention is to provide a mattress construction composed of an upper body of resilient rubber and a lower -innerspring unit including spaced springs'lconnected with a foundation frame.
v v Still another object of theinventionis to provide amattress constructionof said character in which theupper bodyis formed with a `niarginal recess extending continuously about the periphery thereof in which is arranged a row of border springs-supporting the mattress above the marginal recess. I
Still another object of the invention isfto profvide an inner'spring'` unit. rincludinga foundation frame van upper flexible supporting frame on which the upper rubber .body is arrangedand a plurality of rows of springs arranged between andsecured to' said foundation-and supporting frames. With the foregoing and other objects in view,
reference is now made to .the'following specication and accompanying drawings in which the preferred embodiment ofthe invention is illustrated. In the drawings: Fig. 1- is a topplan viewv of a mattress'construction embodyingthe invention and illustrating the same-with the upper portion thereof partlyY broken away to show. the supporting innerspring unit. y Fig. 2 is an under sideview of theinnerspring 4u nitshowing the upper portion of the mattress lin outline.

VReferring to the Vdrawings by characters .of reference, the mattress construction includes an upper resilient body I0 preferably fashioned of foamrubber and which is of rectangular-forma'- kplan extending throughout th'upper tion in portion `of the mattress having. plane upper and lowenfaces I2 and I3 and formed with amarginalrecess I4 extendingv continuously about the periphery thereof.
c I0 is vsupported .upon an innerspring unitl I5 whichA includes longitudinally Aand transversely extending rows of bowed or semi-circular .springs lII which are prefer'arbly fashioned from"flat spring stock and have voutwardly extending U-shaped bends I1 formed therein. intermediate of the height thereof and .upper and lowerdepending U-shaped bends I8 and I9 formed in the ends thereof. The innerspring unitalso includes a foundation frame lindicated generallyby the reference characterl which is of rectangular formation and is located centrally below the lupper body I0 inwardlyof the marginal.A recess I4 with the opposite sides 2| and opposite ends 22 being located below the vouter longitudinal and transverse rows` of springs I6.' The sides and ends 2| and122 are of Y inverted U-shaped formation in Vcrossfsectionallconiiguration vand the'frame is provided with transversely extending vbars 23 secured at their ends to the opposite sideskZI thereof and which are also of inverted U-shaped formation in cross-sectional configuration.V TheV ends 22 together with the bars 23 of the frame` correspond in number to theV number of transverse rows vof springs I6 and said ends and bars `are formed with longitudinally .extending spaced slots 24 in the top wall thereof through which -protrude the lowerY U-shaped bends I9 .withthe lower endsof the springs disposed upon the top walls and the U-shaped bends I9 forming`loops below the top walls through which extend .wires 5v for securinguthe` springs to the foundation frame Disposed above the ends-22 of` saidframe yand the transversely extending bars l23 Ythereof 4are transversely extending spring strips- 26 which underlie the upper ends of the Vsprings I6 in the transverse rows-thereof'I and have longitudinally extending spaced slots*4 21 -through which protrude the-upperjU -shaped bends I8 with the lower portions .thereofy forming loops through Vwhich protrude longitudinallyextendingawires- 28,1for'securing the rows'of springsto lsprings. to Said strips.
said springs are connected together' by longi-l tudinally extending spring strips l32 arranged centrally beneath the intermediate convolutions 3| of the springs in the two longitudinal rows and by transversely extending spring strips 33 are ranged centrally beneath the intermediate convolutions 3| of the springs in the two transverse rows. Y The' said -strips have spaced tongues 34 struck up from `the body thereof which are bent downwardly over opposite portions of the intermediate convolutions 3| for securing the coil Upper and lower Wire members 36 and 3-'| surround the rows of border or peripheral springs 33 and are secured tothe outermost convolutions thereof by clips 33 to thereby reinforcek the upper and lower peripheral edges ofthe innerspring unit and connect the border or peripheral springs together at the upper and lowerends. The transversely extending strips 26 are-secured at their opposite ends to the longitudinally extending `strips Y32 and the longitudinally extending strips 32 are Vsecured at their ends ,to the ends of the ,transversely extending strips. 33 so that the border springs 3E] together with vthe bowed springs I6 and the foundation ,frame 2.0.and .the strips 26, 32 and 33 are connected together to comprise the innerspring unit I5.
Inorderto reinforce the under side of the resilient body I longitudinally extending spring strips `39 are arranged in ,transversely spaced relation against the lower face I3 of said body with the opposite end portions40 of said spring strips extending langularly through the body and secured in position by wires 4| extending through looped `ends 42 protruding into the recesses I4. Any rpreferred number of spring strips 39 may be utilized and as illustrated the strips are arrang-ed to cross over and engage with the transversely extending `strips 26 centrally above the semi-circularsprings I6.
fwire 48 extending continuously about the inner side faces of the sides and ends 2| and 22 of the foundation frame 20. In order to stretch or tighten vthe outer casing or ticking 4'| metallic members49 extend through openings 50 in the inner legs of the sides and ends of the Vfoundation frame andsaid members have sharpened outer ends which pierce through the casing or ticking and are'bent Vinwardly to tighten and hold 'the same in stretched or taut condition. The opposite ends of said members 48 are held in position between the wooden inserts 46 and the inner legs of said sides and ends of the foundation frame. Y
The spring strips 26, 32 and 33 preferably consist of flat spring metal which will flex and bend ,with the weight imposed upon the mattress Construction whereby any portion of the innerspring construction will flex and bend without distorting the surrounding or other portions thereof.

5. In a mattress construction, an upper body of resilient cellular material extending through- `out the area of the mattress construction having a plane upper face constituting the .Supporting surface thereof, an innerspring structure including a series of springs arranged with their axes disposed horizontal and supporting the central area of the upper body, a row of coil springs surrounding said series of springs and arranged with their axes disposed Vertical and supporting the outer peripheral portion of the upper body, a rigid frame structure secured to the lower ends Y of said series of springs, and resilient strips secured to the upper ends of said series of springs and to intermediate convolutions of said coil springs` respectively.
6.
