8 Claims.

The invention relates to mattresses oi the class comprising an inner resilientV construction and more particularly it relates to mattresses having top and bottom covers and filling material connected with the resilient construction in a Inanner to provide a multi-cushion eifect and to prevent the filling material and covers from shiftingrelative to the resilient construction.

The invention has among its objects the provision of an improved method and means for securing the top and bottom covers and lling material to the edges of the resilient construction and to the border boxing or covering material whereby temporary distortions of the edges of the resilient construction under concentrated loads are minimized and permanent distortions thereof are prevented, and whereby loads on the mattress inside of the border tend to maintain verticality of the border boxing by exerting a pull thereon.

Another object of the invention is the provision of improved means for fastening the top and the bottom covers and filling material to the spring construction to provide intermediate zones of depression giving a tuftless multi-cushion effect to the body of the mattress and preventing shifting of the filling material and covers relative to the spring construction.

Still another object of the invention is the 3 provision of a unitary multi-cushion mattress so constructed that all bending of the mattress in handling occurs at the connecting lines of the cushions where the filling material is compressed and is prevented from pulling apart or buckling by the folding of the mattress.

A further object of the invention is the provision of an improved mattress comprising a main body portion `and a border boxing wherein both the body portion and boxing are adapted to be separately constructed as complete units before attaching the boxing, the body portion comprising top and bottom covers and filling material, an inner spring construction having border and intermediate reinforcing members, and novel means connecting the reinforcing members with the covers and lling material to provide zones of depression producing a multi-cushion eifect.

Still another object of the invention is the provision of a novel method of construction and assembly of a mattress comprising an inner spring construction having border and intermediate reinforcing members, top and bottom covers Aand lling material, and an edge boxing.

A still further object of the invention is the 55 provision of an easily assembled, durable multicushion mattress of the kind described providing border reinforcing elements adapted to distribute loads and to maintain the edge boxing taut.

Many other advantages of. the construction herein shown and described will be obvious to those skilled in the art from the disclosure herein given.

To this end the invention consists in the novel construction, arrangement, and combination of parts herein shown and the novel method of assembly as described and more particularly pointed out in the claims.

Referring now to the drawings forming part of the specication and representing preferred embodiments of the invention:

Fig. 6 is a view along the and Fig. 4;

Fig. 7 is a view along the line 1-1 of Fig. 2; and

Fig. 8 is a fragmentary sectional view of an alternativerconstruction embodying the principles of the invention. 35

Referring now more particularly to the drawings, the numeral l0 generally designates a triple- `cushion mattress shown in perspective and embodying either the preferred or alternative forms of the invention.

The mattress comprises an inner unitary spring construction consisting of a plurality of vertical coils Il preferably arranged .in longitudinal and transverse rows, the border coils being connected at top and bottom by helicals I2 extending around the spring construction and the intermediate longitudinal rows of coils being connected by helicals I3 at their tops and bottoms with the contiguous coils arranged in adjoining longitudinal rows.

A partial longitudinal section of the completed mattress is shown in Fig. 3 as comprising a border boxing I4 fastened to the main body of the mattress in a manner hereinafter more particularly described. The main body of the mattress is lines 6-6 of Fig. 1

adapted to be assembled and completed as a unit before attaching the boxing I4, the various components of the mattress being shown in assembled and partially disconnected relation in Fig. 5. The top and the bottom of the mattress each comprises a lining I5 contiguous to the spring construction, a layer I6 of sisal or similar material fastened to the lining by stitches I'I, a layer of lling material I8, and a fabric cover I9. In some cases the sisal I6 may be omitted and if so, the thickness of the filling material is correspondingly increased. 'I'he lining I5, sisal I6, filling material I8, and cover I9 are pre-built and assembled to provide top and bottom pads respectively for the spring construction, the elements comprising each pad being connected by lines of stitches 20. The stitches 20 extend across the pads and also fasten strips 2| of cloth or other suitable material to the linings I5, the stitches being so formed as to more or less compress the filling material I8 and the sisal I6 as shown in Figs. 4, 5, and 6. The lines of stitches 20 are preferably connected With the middle of the strips 2I and the strips are then folded along the lines of stitches as shown.

The strips 2| of the top and bottom assemblies or pads are then successively fastened to the adjacent helicals I3 of the spring construction preferably by curved metal rods or Wires having pointed ends forced together to form links or rings 22 more or less similar in construction to hog rings. The strips 2l are pulled down to a position wherein their inner edges are contiguous to the helicals I3, as shown in Figs. 4 and 6, and are fastened by piercing the strips with and inserting the open rings' 22 through adjacent helicals, the rings being then` closed by pressing their ends together by pliers or other suitable instruments. The ends of the strips 2l extend over and are respectively fastened to the border helicals I2 by the rings 22 as shown in Fig. 6 to maintain the strips taut longitudinally as well as vertically. The strips 2I compress the pads equally against adjacent coils and prevent tilting of the adjacent coils. The metal rings 22 arerinilexible, simple, and easily manipulated and are preferably used as fastening means although cords or stitches may be substituted if desired.

The top and bottom pads, fastened as described to the spring construction, form three tuftless cushions separated by transverse zones of depression coinciding with the lines of stitches 20, as shown in Fig. 1. By providing unitary pads consisting of three cushions, it will be observed that the positions of the cushions respectively correspond to the positions of the shoulders, hips and feet of an occupant whereby the maximum cushioning effect is obtained and the body does not contact with the compressed portions of the pads. The middle cushion carries the maximum body weight and is preferably provided with filling material of greater thickness than the end cushions to increase the resiliency.

I'he construction and assembly of the main body of the mattress is completed by fastening the covers I9 to the contiguous edges of the spring construction by means of flaps 23 extending around and previously connected with the covers by a line of stitches 24 spaced at a suitable distance from the margins of the covers. The flaps 23 consist of fabric sheets folded upon themselves with the line of fold contiguous to the border of the spring construction and enclosing a reinforcing wire or rod 25. 'Ihe flaps 23 are drawn taut and are fastened to the ends of the adjacent border coils II and to the lining I5 preferably by means of metal rings or links 26 respectively engaging the coils and piercing the flaps to encircle the reinforcing Wires or rod 25, although it is understood that loops or cords may be used instead of the rings if desired. The rings 2B are similar in construction and are manipulated for fastening the aps 23 to the coils II in the same manner as described for the rings 22 in fastening the strips 2| to the helicals I2 and I3. The flaps 23, fastened as described to the spring construction, maintain the covers I9 taut and thereby contribute to provide smooth billowing expansive surfaces for the cushions comprising the top and bottom pads. The wires or rods 25 carried by the flaps 23 reinforce the borders of the mattress and prevent excessive yielding of the spring construction and the adjacent boxing under concentrated loads applied to the border since the Wires tend to distribute such loads over larger areas and as a result temporary distortions of the boxing and marginal coils by such loads are minimized and permanent distortions of the edge of the mattress are prevented by reason of the pull exerted on the coils by the flaps. The use of metal rings 26 for connecting the flaps 23 with the spring construction instead of looped cords, or stitches increases the utility of the Wires or rods 25 as reinforcement for the border of the mattress since the rings are unyielding under tension transmitted from the flaps and wires 25 to the spring construction and are more durable than lacings of fibrous material. Obviously loads applied to the mattress inside of the border tension the cover sheet I9 and flaps 23 and thereby maintain verticality of the edge coils connected as described with the flaps and reinforcing rods 25. The edge reinforcement also tends to prevent unequal sagging of the mattress when occupied by two personsA of unequal Weight.

The reinforced pads and spring construction comprising the main body of the mattress having been completed as described, its edges are then enclosed by any suitable boxing material to provide a finishing mattress. The edge material used is illustrated as comprising a pre-built continuous strip of boxing 2l consisting of an outer ply 28 of a Width substantially equal to the depth of the completed mattress, a ply of filling ma terial 29 of substantially greater width than the depth of the mattress and a fabric sheet 30 enclosing the filling material, all fastened together preferably by eyelets 3| as shown to form a quilted boxing.

The top and bottom edges of the lling material 29 enclosed by the ber sheet 30 are connected with the reinforcing rods 25 in the flaps 23 bymeans of cords 32 looped at intervals through the boxing and through the flaps 23 to engage stitches would detract from the ornateness of the 5f finished mattress. The projecting edges of the boxing lling material 29 encased by the sheet 30 are next successively folded as shown to engage the flaps 23 and to permit the adjacent marginal edges of the covers I9 and ofthe outer boxing ply 28 to be brought together and covered by a tape 33. The marginal edges ofthe covers I9 and of the boxing ply 28 areturned inwardly and the tape 33 folded over the' borders and connected therewith by any suitable stitching 34.2

The folding of the projecting edges of the boxing material produces a rolled edge effect, and the tension of the cover sheets I9 produced by loads on the mattress inside of the border will maintain the verticality of the boxing under all ordinary loads.

The alternative embodiment of the invention illustrated in Fig. 8 comprises a pre-built main body portion consisting of an inner spring construction and top and bottom pads or assemblies of material, enclosed by a border boxing 2'I, sub stantially similar in all respects to that described for the preferred embodiment except that the covers I9 have no border flaps or interior metal reinforcement corresponding to the wires 25. The pads comprising the top and bottom portions ofthe alternative embodiment are connected to the spring construction to provide Zones of depression inthe same manner as described for the preferred embodiment. Each assembly has a cord 35 stitched through the lining I5, sisal I6, filling material I8 and cover I9 adjacent its border. The marginal edges of the linings I5 extend around the adjacent border helicals l2 and are fastened to the spring construction by a plurality of spaced apart spring clips 36 each piercing the lining. A cord 31 similar to the cord 32, looped at intervals through the boxing lling material 29 and strip 30, and through the adjacent coils I I, fastens the boxing to the lining I5 and the spring construction. The projecting edges of the boxing are then successively folded over against the filling material I8 covering the top and the bottom of the spring construction. The marginal edges of the covers I9 and the outer boxing ply 28 are then brought together rand connected by stitching 34 extending through the tape 33.

The division points of the cushions correspond to the spaces between the coils and in the first or preferred form each side flap is provided with three rods 25 stopping short of the division points of the cushions. All of the rods 25 have looped ends to prevent puncturing of the flaps. Longitudinal movement of the rods 25 is prevented by engaging a ring similar to the rings 26 with the looped ends. The side rods 25 conne the bending of the mattress to the compressed areas connecting the cushions.

By way of summary. the construction and assembly of a finished mattress lembodying the principles of the invention are as follows:

A unitary spring construction comprising vertical coils II connected by border and intermediate helicals I2 and I3 respectively having been prepared, and a top and a bottom assembly each consisting of a lining strip I5 and a fabric cover I9 having layers of sisal I6 and of filling material I8 positioned therebetween and all connected of stitches 20 engaging fabric together by lines strips 2l arranged as described and shown in perspective in Fig. 5, one of the assemblies is positioned on the spring construction and its ends folded over to permit access to the strips 2l. The strips 2I are in turn connected with the spring construction by successively pulling the strips into contiguity with the spring construction and fastening the strips to the helicals I2 and I3 by means of the rings 22 thereby depressing the assembly along the lines of stitches 20. The border of the assembly is then fastened to the spring construction by pulling taut the flaps 23 containing the reinforcing wires or rods 25 and successively inserting rings 26 through the flaps, the lining I5 and the adjacent coils II.

shown in Fig. 8 except One side of the pre-built pad comprising the main body of the mattress having been completed as described, the spring construction is then turned over and the other assembly is positioned on and fastened thereto in the same manner, thereby completing the assembly and construction of the main body of the mattress.

'Ihe next and nal steps in providing a finished mattress consist in positioning the boxing 2l around the edge of the completed body portion, connecting the adjacent edges of the boxing and flaps 23 by the cords 32, then folding the edge of the boxing over onto the flaps and fastening the margins of the cover I9 and of the boxing ply 29 together and to the tape 33 by means of stitches 34. The mattress is then turned over and the other edge of the boxing is similarly fastened to the adjacent flaps 23 and to the cover I9.

The foregoing summary of the assembly and lconstruction of the preferred embodiment also summarizes the various steps of assembling and construction of the alternative embodiment that the layers or plies of the pad are fastened together adjacent their edges by means of cords 35 and the linings I5 are connected to the spring construction by clips 36. The final steps of connecting the boxing 21 with the pre-built body are substantially identical with those described in connection with the completion of the preferred embodiment.

Thus, it will be seen that the invention provides improvements in mattresses of the kind described whereby the spring construction and facing materials or bodies are suitably connected to provide a plurality of cushions and to provide reinforcement for the border of the mattress before attaching the boxing and that the invention provides a novel sequence of steps in the assembly and construction of the mattress and novel fastening means adapted to minimize temporary distortions of the mattress under concentrated loads and to prevent permanent distortions both of ther body of the mattress and of the borders thereof.
