FACE REST MATTRESS Filed Oct. 11. 1961 2 Sheets-Sheet 2 INVENTOR. ANTHONY F? ROMAN ATTORNEYS United States Patent 3,135,974 FACE REST MATTRESS Anthony P. Roman, 100 Remsen St., Brooklyn 1, N.Y. Filed Oct. 11, 1961, Ser. No. 144,348 11 Claims. (Cl. -345) This invention relates to therapeutic mattresses for beds and the like, and more particularly to a mattress for people who sleep or rest face downward.
Many persons prefer to sleep in a prone, or face down position, and there are others who find it necessary to sleep in a prone position to relieve certain abnormal strains and tensions of the body, particularly in the neck and back.
Heretofore, it has been difiicult for many persons to sleep in a completely prone position, since the head must be turned to one side in order to provide for normal breathing, or a pillow must be used to raise the head and alleviate pressure on the nose and mouth and provide breathing space. In the former case, a proper prone position is not achieved because of the twist in the neck, While in the latter case, the neck is bent back in an awkward and uncomfortable manner that makes complete relaxation impossible.
In addition, there have been many cases of infants requiring special prone positions for sleeping, but this is a situation fraught with danger, as the infant may spit up food and have difiiculty in breathing. In cases like this, suffocation is an ever-present danger.
The primary object of this invention is to provide a mattress for face down or prone sleeping, wherein means is provided to allow free and normal breathing.
Still a further object of this invention is to provide a mattress adapted to assure a fresh air supply to the sleeper at all times.
The foregoing and other objects and advantages of this invention will become clear to those skilled in the art from the following description, when read in conjunction with the attached drawings, in which:
FIGURE 1 is a plan view of the mattress embodying the principles of the present invention;
FIGURE 2 is a sectional view of the same, taken at C--C of FIGURE 1;
FIGURE 3 is a sectional view of the same taken at B-B of FIGURE 1;
FIGURE 4 is a sectional view of the same taken along the line A-A of FIGURE 1;
FIGURE 5 is a view similar to FIGURE 4, but shows a modified embodiment of the head portion of the mattress;
FIGURE 6 is a View similar to FIGURE 4 showing another embodiment of the head portion of the mattress;
FIGURE 7 is a view similar to FIGURE 4 showing still another embodiment of the head portion of the mattress;
FIGURE 8 is a view similar to FIGURE 4 showing still another embodiment of the head portion of the mattress;
FIGURE 9 is a cross sectional view of still another embodiment of the head portion of the mattress;
FIGURE 10 is a plan view of another embodiment of the therapeutic mattress;
FIGURE 11 is a plan view of still another embodiment of the mattress;
FIGURE 12 is a broken oif plan View showing still another embodiment of the head portion of the mattress; and
FIGURE 13 is a broken off plan view showing yet another embodiment of the head portion of the mattress.
In the drawings, the mattress is generally indicated at 2 and is of conventional overall proportion having a head end 4 and a foot end 6.
The mattress may be of any conventional internal construction, such as inner spring, foam rubber, isocyanate foam, and the like. For purposes of illustration, the mattress shown in the drawings is of foam rubber construction, the cushion material of which is designated 8. The cushion material is covered by a suitable material 10, such as cloth.
The head end 4 of the mattress contains a plurality of indentations or corrugations for air circulation such as slots or grooves 12 spaced across the mattress and extending from the head of the mattress in the direction of the foot to a distance equal to about 0.1 to 0.33 times the length of the mattress. Ordinarily the indentations will vary from about 0.5 to 2 feet in length.
The indentation may take the form of elongated slots or grooves, having a variety of cross sectional shapes, such as circular (FIGURES 4 and 5), sinusoidal (FIGURE 6), angular (FIGURE 7), and rectangular (FIGURE 8). Other shapes will readily suggest themselves to those skilled in the art.
The slots or grooves may have a width at the upper surface of from about 1 /2 to 5 inches, and a depth of from about 1%. to 3 inches or more. The spacing between the slots or grooves can be variable, although generally the space between the indentations will be less than the width of the sleepers face, and generally less than about 4 inches.
The spacing of the indentations may be regular or irregular, although generally it will be regular.
The slots or grooves are preferably arranged parallel to one another and have axi parallel to the sides of the mattress as shown in FIGURE 1. This is, however, not necessary, and other configurations may readily be en visaged. In FIGURE 10, for example, the grooves 12 are arranged in a series ofconcentric circles. In FIGURE 11, the grooves are arranged in a fan-shaped pattern, and at least some of the grooves have longitudinal axi which forms an acute angle with the sides of the mattress.
In FIGURE 12, the grooves extend horizontally from side edge to side edge of the mattress in a direction transverse to the side edges and parallel to the end edges of the mattress.
The grooves need not be continuous, but may be discontinuous, as shown in FIGURE 13. In FIGURE 13, the plurality of discontinuous indentation 13, although shown as rectangular in cross section, may be a variety of other suitable shapes. As also shown in FIGURE 13, these indentations may also form a wafile-like pattern.
In another embodiment of the invention shown only by the cross sectional view of FIGURE 5, a porous elastic web or corrugated elastic webbing 14 may be superimposed over the head end of the mattress across the indentations 12 and affixed to the mattress at its sides. This web will flex under pressure from the sleepers head and will facilitate making of the bed without interfering with circulation of air through the slots or grooves 12.
When the webbing is not used, the mattress cover 10, rather than following the contour of the indentations, as shown in the drawings, can be stretched over the indentations in the same manner as the web of FIGURE 5. In this embodiment, care should be used to insure that porous fibers for the mattress cover are employed.
If desired, the head end of the mattress containing the indentations may form an angle such as from about 1 to 30, with the main body of the mattress, thereby enabling the head of the sleeper to be elevated with respect to his feet.
Although in the embodiments shown, the slots or grooves extend clear to the edge of the mattress, this is not necessary, and, if desired, the slots and grooves can end a short distance from the actual edge of the mattress.
Preferably, however, the indentations are co-terminous with the edge of the mattress.
Also, if desired, the indentations can be provided on both sides of the mattress, to enable the mattress to be regularly turned with use, as is shown in FIGURE 9.
It will be understood that beds using the mattresses shown herein may be made in the conventional way with conventional bed clothing and sheets, and do not require costly special sheets or bed clothing. The sheets may be stretched over the mattress, including the head portion thereof. Because of their porosity, little interference with circulation of air into and out of the grooves is occasioned by the sheeting material. Of course, if thick mattress padding is employed, this should not cover the indentations at the head end of the mattress.
Regardless of the shape of the indentations, these should be gently rounded at their upper surfaces so as to avoid sharp edges, as is shown in the drawings.
The invention in its broader aspects is not limited to the specific article of manufacture shown and described herein, but departures may be made within the scope of the accompanying claims without departing from the principles of the invention and without sacrificing its chief advantages.
