2 Claims.

This invention relates to improvements in sectional mattresses and has as its object to provide a mattress having two or more sectional members so constructed as to be adapted to be interchanged and to be secured together to provide a substantially unitary mattress presenting a substantially continuous upper surface.

A further object of my invention is to provide a sectional mattress of the character described with means secured to, superimposed on and co,- extensive with the upper sqlrfaces of the mattress sections, providing, in conjunction therewith, an even distribution of the weight supported by the sections.

These and other advantageous objects, which will later appear, are accomplished by the simple and practical construction, combination, and arrangements of parts hereinafter described and shown in the accompanying drawings, wherein like reference numerals indicate like parts and wherein:

Fig. 1 is a perspective view of sections of a mattress made in accordance with my invention,

Fig. 2 is a fragmentary perspective view takenon line Z--2 of Fig. 1 in the direction of the arrows, revealing details of construction of the means for securing marginal edges of the mattress sections together in accordance with my invention,

Fig. 3 is an enlarged fragmentary vertical transverse sectional view taken on lines 3-45 of Fig. 1, indicating further details of the means for uniting the mattress sections,

Fig. 4-is a fragmentary end elevational view of sectional members embodying my invention, showing the relative juxtaposition of the parts when the mattress is positioned on an irregular surface, Fig. 5 is a top plan view of a member adapted to be superimposed over the upper surfaces of assembled sectional members as in Fig. 8, to provide, in conjunction therewith, an even distribution of the weight supported by the sections,

Figs, 6 and '7 are fragmentary underplan views taken on lines 6-6 and 1-1 respectively of Fig. 5, and Fig. 8 is an end elevational view of a mattress embodying my invention, shown positioned on an angularly disposed surface.

In the drawings, in Fig. 1 there is shown a .mattress embodying my invention, comprising two or more sectional members Ill, each of which is of generally rectangular configuration, having side and end walls ii and I2, respectively. The

, themselves as shown in Figs. 6 and '7 so thatone edge i l, to the mattress section, preferably,

as indicated in Fig. 3, intermediate horizontally disposed ends it and iii of strips secured to or integral with the sides and -top portions of the mattress section, respectively. The free ends I! of fabric strips 53 are provided, as shown in Fig. 3,

. with complementary halves of fastener units of adjacently disposed strips i3 whereby, by aligning the sectional members in parallel spaced relation with the slide fastener halves in abutment, said sections may be secured together at their longitudinal edges. The strips it are freely flexible to enable the sections III to be angularly disposed relatively to each other as in Figs. 4 and 8 to conform to the surface S on which the mattress is placed or to permit airing of the mattress. The sections lil may be thus secured together at their upper and .lower longitudinal edges, as in Fig. 1, to present a substantially unitary and rigid mattress with a continuous upper supporting surface, the mattress being adapted to be separated into individual sections for removal, rearrangement or replacement of sections. As shown in Fig. 5, the mattress of my invention may be provided with an elongated member 26 preferably made in the ,form of a of further providing an even distribution of the weight to be supported by the mattress and providing, in conjunction therewith, a substantially continuous supporting surface as shown in Fig.8. The elongated member 20 is provided on the underside, adjacent the transverse ends thereof, with complementary halves 2|-22 of continuous, separable, slide fastener units secured to fabric trips 23-24 respectively, said fabric strips being secured at their other edges to the underside of member 20; the fabric strips may be curled upon the slide fastener elements carried thereby will be disposed in the same plane as the member 20 but spaced therefrom and directed inwardly away from the ends thereof as clearly shown in Figs.

2 6 and '7. By superimposing member over the mattress sections as in Fig. 8, the fastener elements of the elongated member 20 may be engaged with the complementary elements of the fabric strips 13 at the ends of the mattress.

The unitary characteristics of the mattress are thus enhanced and an even distribution of the weight supported by the mattress is further assured. For the purpose of providing even greater rigidity to the fastening means embodying my invention, the fabric strips I! may be provided with reenforcing longitudinal rods secured thereto in any desired or convenient manner, as for example, by straps it sewed or otherwise secured to the fabric strips [3, said straps being preferably coextensive with the length of the fabric strips l3 and being preferably provided with closed ends 28 as shown in Fig. 2 for the purpose of preventing displacement of said rods 25. As will be noted from Fig. l, the fabric strips I! are so arranged that a like pair of halves of fastener elements will be disposed at each of the sides I i of the mattress, to enable the mattress sections to be reversed, replaced and interchanged at will'and to enable a the member 20 to be secured thereto if desired from time to time.

It will be noted that when the mattress sections are secured together in accordance with my invention, (as indicated in Fig. 1) at adjacent upper and lower marginal edges, a substantially unitary and rigid structure is provided; when, as indicated in Figs. 4 and 8, the mattress sections are secured together at only their upper longitudinal marginal edges in accordance with my invention, a substantially continuous upper surface conforming to the configuration on thesurface on which the mattress is positioned, is provided the structure of the fabric strip members 13 and its arrangement on the mattress providing for the free flexing and pivoting of the sections relatively to each other while maintaining a positive and reenforced interconnection between the mattress sections and presenting a continuous and firm upper surface at all times.

Thus the mattress has proven admirably adapted for use in hospitals, conforming readily to the various arrangements of the Gatch type of bed, the replaceable characteristics of the mattress permitting removal and rearrangement of its sectional members and thus prolonging the value and life of the mattress.

The features described also facilitate the handling of the mattress and airing thereof.

In carrying out my invention, the mattress sections may be secured together at adjacent upper marginal edges only as shown in Fig. 8,

or alternately, at upper and lower marginal edges to enable the sectional members to be arranged at different planes in conformity with the sur= face of a Gatch type bed or other irregular surface on which the mattress is placed.

The mattress of my invention may be provided with only one elongated member 20, superimposed over the upper surface thereof, or a pair of such members 20 may be provided, the second member being superimposed over the lower surface, in the same manner as heretofore described, and which will become apparent if,

2,247,667 I on viewing Fig. 8, one were to assume that the mattress is inverted with the lower surface appearing uppermost.

Having thus described my mventicn, what I Patent is:

i. A mattress comprising two or more elongated sectional members of rectangular configuration, each member being provided with side and end walls and corners, said member having secured to the side walls at the upper edges thereof elongated fabric strips protruding beyond the planes of the sides thereof, said strips being secured, at one edge, to the mattress section, providing for the free flexing and pivoting cf the fabric strips, separable fastener units secured to and coextensive with the free ends of the fabric strips, whereby, by aligning said sectional members in parallel relation with the fastener units in abutment, said sections may be secured together at their upper longitudinal edges with the abutting separable fastener units intermediate and pivotally connecting the mattress sections at their upper longitudinal edges, to enable movement of the sections angularly relatively to each other while presenting a substantially continuous "upper surface and with separable fastener units along the outer transverse edges of the end mattress sections, a pad member, and fabric strips curled upon themselves and secured at one edge along the under side of the pad member adjacent the outer trans-. verse edges thereof, the free edges of the fabric I thereof elongated fabric strips protruding beyond the planes of the sides thereof, said strips being secured, at one edge, to the mattress section,

providing for the free flexing and pivoting of the fabric strips, separable fastener units secured to and coextensive with the free ends of the fabric strips, whereby, by aligning said sectional members in parallel relation with the'fastener units in abutment, said sections may be secured together attheir upper longitudinal edges with the abutting separable fastener units intermediate and pivotally connecting the mattress sections at their upper longitudinal edges to enable movement of the sections angularly rela-' tively to each other while presenting a substantially continuous upper surface and a pad member coextensive with said upper surface, and

separable fastener units secured at the outer transverse edges of the pad adapted to be engaged with the fastener elements of the fastener units along the outer transverse edges of the end mattress sections.
