5 having a rubber-like resiliency.
The mattress made by my invention may be used for manifold purposes and it is particularly the object of the invention to provide means which will give a greater comfort to both well and sick people, by giving relief from the feeling of becoming unduly heated as is now the case with upholstered seats or inflated rubber bags.
It is also an object of the invention to provide a mattress for the greater comfort of the people at places where there is a constant change of the occupants, for instance, as in hotels and hospitals, by supplying mattresses which can be easily disinfected and air ventilated.
With these and other objects in view, which will be more apparent as the description proceeds, I shall describe below my mattress and refer to the accompanying drawing, in which Figure 1 is a fragmentary perspective view of a mattress, parts being broken away to more fully disclose the arrangement;
Figure 2 shows a perspective view of one of the members connected with and supporting the upper and lower blanket of the mattress, parts of said supporting member being broken away to more closely illustrate the arrangement.
In the drawing the numerals 10 and 11 denote two blankets made of porous rubber similar to the universally known rubber sponges. The two blankets are of the same dimensions as to be con gruent to each other; they are disposed parallel to, and, therefore, substantially equidistantly from each other. In the space between the blankets 10 and 11 elongated supports 12 are suitably perpendicularly arranged upon and joined to them in any suitable way. The supports 12 are built up by three plates 13 of the same size, preferably of the same square form and thickness or height, a square member 14, somewhat higher than a plate 13, being interposed between the one set of plates l3 and a cylinder 15 being interposed between the alternately disposed at the bottom and at the top of the support 12.
Moreover, all parts, blankets l0 and 11 as well as supports 12, are made of porous rubber, and it is obvious that when a person rests on the mattress and presses his'weight upon the supports 12, the air gradually escapes through the walls from within the space 16 whereby the resiliency of the mattress and the comfort to the user is greatly increased. With every movement of the user the space 16, owing to the resiliency of the rubber assumes its original form and thus air rushes in and fills space 16, by this alternate escape of the air from and its re-entrance into the space 16, the mattress is continuously ventilated.
Inasmuch as the air may freely circulate through the blankets 10 and 11, and as particularly the open framework of the elastic supports 12 allows the air to have free access to the blanket 10.
Another great advantage of my new mattress is that it can be easily washed, disinfected and sterilized, either by heat, or by simply washing it with water, soap suds or any disinfectant solution, all of which do not affect rubber. 0n account of its porosity such a mattress dries rather quickly; particularly when it is systematically dried by application of heat and air, it can be available again within a few hours to meet the highest sanitary requirements.
I, furthermore, wish to have it understood that it is not absolutely necessary that the upper blanket 10 is consisting exclusively of one piece; it may be subdivided into a plurality of sections, which suitably are all of the same surface dimensions.
What I claim is:
1. As a new article of manufacture, a mattress consisting of upper and lower blankets of porous rubber, a pluralty of supports, each support consisting of a set of three porous rubber sheets arranged one above the other, a square sheet of similar porous rubber arranged between and secured to two sheets of each set, said similar sheet having a centrally located hole, and a sheet corresponding in size and shape to said hole secured to and arranged between the third sheet' and one of the other set of sheets so as to register with said hole.
2. As a new article of manufacture, a mattress consist of upper and lower blankets of porous rubber, the blankets being retained in parallel relation to each other by a plurality of supports, each support being formed by a set of three porous rubber sheets arranged one above the other, a similar sheet of porous rubber arranged between and secured to two sheets of each set, said similar sheet having a substantial part of the inside material cut away to form a hollow space, and a sheet corresponding in shape and size to said hollow space, the last mentioned sheet being secured to and arranged between the third sheet and one of the other sheets of the set so as to register with said hollow space.
3. As a new article of manufacture, a mattress consisting of upper and lower blankets of porous rubber, a plurality of supports, each support consisting of a. set of three spaced solid sheets of porous rubber, a hollow member of porous rubber interposed between two of said sheets, and a solid member of porous rubber interposed between one of said two sheets and the third of said three sheets, said solid and hollow'members being oi. less extent than said sheets.
