Description
1. Field of the Invention
This invention relates generally to a resilient cushion assembly for the support of the body and, more particularly, to a mattress cushion assembly which provides first and second support surfaces having varying degrees of firmness and further including a hinged stiffener member disposed between the first and second support members to allow for folding or rolling-up of the cushion assembly.
2. Description of the Prior Art
The conventional mattress typically provides a single degree of support to the body due to the substantially homogeneous nature of the cushioning material disposed therein. Such a single degree of support, while adequate for most purposes, may prove inadequate depending upon the support preferences of the user. A need has thus arisen to provide variable cushion support within a single cushion or mattress. An attempt to realize such objectives has been tried using a plurality of selectable surfaces having varying hardnesses.
A mattress directed generally to the provision of a plurality of selectable surfaces of varying hardnesses is shown by Johnson in U.S. Pat. No. 2,721,339, which discloses a mattress having two superposed halves joined together in a manner enabling one half to be swung over and upon the other half. A first half of the mattress is provided with a plurality of hardboard panels, while the second half consists of a uniform construction of cotton batting. The second half does not have any panels disposed therein. The panels are placed in the first mattress half relatively close to the sleeping surface. Such assembly allows for bidirectional flexing of the panels both toward and away from the sleeping surface. However, should the two mattress halves be encased within a mattress cover, removal of the cover would be required in order for the full range of hardnesses to be available to the user.
Thus, there exists a need for a simple mattress or cushion assembly which provides for uni-directional flexing of support panels disposed therein as well as for a mattress or cushion assembly which obviates the removal of a mattress cover in order to allow for a full choice of mattress hardnesses.
Accordingly, this invention has been made to meet the needs discussed above and, therefore, has an object to provide a cushion support assembly which offers a user a choice of support stiffnesses and which facilitates the conversion of the assembly from a first mode of stiffness to a second mode of stiffness.
A further object is to provide a compact support unit having a standard thickness so as to eliminate the necessity of a box spring unit.
A still further object of the invention is to facilitate the application and retention of covers or sheets about the mattress assembly.
Another object is to provide a mattress allowing substantially uni-directional flexing such that flexing is permitted in only a single operative mode of the assembly.
Another object is to provide a mattress assembly having a support baseboard so as to eliminate the necessity of a box spring unit.
Yet another object is to provide a mattress capable of being folded or rolled into a compact unit for storage.
Another object is to provide a cushion in accordance with the invention and adaptable for use with furniture such as couches, chairs, or with pillows or seat cushions.
The foregoing and other objects are achieved according to the present invention by the provision of an assembly for the support of the body, which includes a base support board overlying a bed frame for providing a substrate or support base for the mattress. Firm and soft mattress sections are joined to a center piece stiffening board composed of a plurality of transverse abutting hinged sections. The stiffener board is dimensioned so as to provide a peripheral recess at the junction of the top and bottom mattress sections. Such hinged pivotable sections allow for the rolling up of the mattress assembly to form a compact unit thereby facilitating storage.
Various other objects, features, and attendant advantages of the present invention will be more fully appreciated as the same becomes better understood from the following detailed description when considered in connection with the accompanying drawings, in which like reference characters designate like or corresponding parts throughout the several views and wherein:
FIG. 1 is an isometric view of the center piece stiffener board;
FIG. 2 is an isometric view of the mattress assembly;
FIG. 3 is a sectional side elevation view of a preferred embodiment of the mattress assembly presenting the firm support surface in an operative mode;
FIG. 4 is a partial sectional view of FIG. 3 taken along lines 4--4;
FIG. 5 is a sectional side elevation of a preferred embodiment of the mattress assembly showing the soft side disposed in an operative mode in a loaded condition;
FIG. 6 is a sectional side elevation view of the mattress assembly in a rolled-up or storage condition;
FIG. 7 is a plan view of a support baseboard for the mattress assembly; and
FIG. 8 is an elevation view of the support baseboard.
The assembly developed in accordance with the present invention will now be described in conjunction with the accompanying FIG. 1, FIG. 2, and FIG. 3, within which, for example, a mattress assembly 1 is disclosed. A firm mattress section 2 is formed of a resilient material, such as foam rubber, having a predetermined stiffness. A soft mattress section 3, also formed of a resilient material, is also provided. The stiffness of the soft bottom mattress section 3 is chosen so as to have a stiffness different from that of the firm top mattress section 2. As shown in FIG. 3, the top mattress section 2 is composed of a firm material, while the bottom mattress section 3 is composed of a soft material, thereby affording the user a choice of mattress stiffnesses, offering varying degrees of support. The firm material may have a density greater than that of the soft material.
The center piece or stiffener board 4 as individually depicted in FIG. 1 is shown disposed between the firm mattress section 2 and the soft mattress section 3 in FIGS. 2 and 3. As further depicted in FIG. 1, the rigid stiffener board 4 may be formed from plastic and may include a plurality of cutouts or perforations 5 formed therein so as to reduce the weight thereof. The center piece stiffener board 4 is permanently bonded or laminated to a hinge material 6 on a single side of the stiffener board 4. The stiffener board 4 is formed from a plurality of abutting transverse sections 8, 9 flexibly joined via hinge material 6. A transverse strengthening ridge 7 is provided along each abutting transverse section on the side opposing the hinge material 6. Such construction ensures unidirectional flexing and increases the structural integrity and stability of the stiffener board 4.
As further depicted in FIGS. 3 and 5, the stiffener board 4 is disposed between and secured to or laminated to the firm mattress section 2 and the soft mattress section 3 so that the hinge material 6 contacts the soft or bottom mattress section 3 while the transverse strengthening ridges protrude into the top or firm mattress section 2. Such an assembly enhances the effect of the user's choice of a firm or soft mattress surface by allowing flexure towards the soft mattress section 3 when the soft mattress section is on top of the mattress assembly 1 adjacent the user, while preventing such flexure towards the firm mattress section 2 when the firm mattress section is on top of the mattress assembly adjacent the user.
Referring to FIGS. 2 and 3, the centerpiece or stiffener board 4 is dimensioned so as to provide a recess 10 of substantially uniform depth along the entire periphery of the junction of the firm and soft mattress sections 2, 3 with the stiffener board 4. The recess may typically have a depth of 2 inches so as to facilitate the fitting of a cover or sheet on both the firm and soft mattress sections 2, 3. Moreover, the mattress assembly 1 may be dimensioned in standard sizes adaptable for use with standard size bedding sheets. Furthermore, the thicknesses of the firm and soft mattress sections 2, 3 as well as the thickness stiffener board 4 are dimensioned so as to form a mattress assembly having an overall thickness approximating the thickness of a standard mattress and box spring assembly, for example, 16 inches.
As depicted in FIG. 4, a plurality of longitudinal separations or joints 11, 12 may be formed in the stiffener board 4 along with a plurality of diagonal separations or joints 13, 14, at each corner portion of the stiffener board so as to increase the flexure of the soft mattress section 3 when placed in an upper or operative mode.
FIG. 5 shows the effect of the stiffener board 4 when the soft section 3 is placed in an upper or operative mode in a loaded condition. Flexure of the abutting transverse sections 8 and 9 about hinge point 15 when under load effects a separation 16 of the transverse strengthening ridges 7 so as to cause the mattress assembly 1 to take a generally arcuate shape as shown. Such arcuate shape is to be contrasted with that shown in FIG. 3 wherein the firm mattress section 2 is disposed on top in an operative mode so as to form a substantially planar support surface wherein the separation 16 shown in FIG. 5 is closed.
In FIG. 6 is shown the mattress assembly 1 in a rolled up or storage condition wherein the soft mattress section 3 is disposed inwardly of the firm mattress section 2 so as to form a roll having a substantially polygonal cross section. Such a shape facilitates transportation and storage.
A rigid baseboard 17 shown in FIG. 7 may be provided having a plurality of hinged sections 18, 19 so as to enable folding thereof or baseboard 17 may alternatively be formed in one piece. Baseboard 17 is dimensioned so as to overlie a bedframe and provide a support base for the mattress assembly 1. The baseboard 17 may also include a plurality of cutouts or perforations 20 to reduce the weight thereof. FIG. 8 shows the hinged sections 18, 19 of baseboard 17 connected by hinge material 21.
While the principle of the present invention has been directed to a mattress assembly per se, the design will also apply to any cushion, couch, pillow, or cushioning support surface applicable for use with various types of furniture such as chairs, couches, or auto or boat seat cushions, pillows or outdoor furniture or camping equipment such as sleeping bags.
Obviously, numerous modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims, the invention may be practiced otherwise than as specifically described herein.
