The present disclosure relates, generally, to a mattress. More particularly, the present disclosure pertains to a mattress that supports a lumbar region of a person when the person lies on the mattress.
Mattresses used for sleeping have been made in more or less the same shape and are made from the same materials since many years. Mattresses typically use layers of foam having uniform thickness and include material having identical hardness and firmness throughout the entire thickness of the layers. Accordingly, the layers of foam are compressed evenly when a person is lying on the mattress. However, the layers of the mattresses do not adapt in an optimum manner to the varying anatomical forms of the persons.
One aspect of this disclosure relates to a mattress. The mattress includes a support layer and a comfort layer arranged supported on the support layer, a support structure sandwiched between the support layer and the comfort layer. The support structure includes a plurality of first bars extending in a longitudinal direction and arrayed in a lateral direction, at least one second bar coupled to the plurality of first bars and supported on the plurality of first bars. The at least one second bar extends in the lateral direction and is configured to facilitate a flexing of the plurality of first bars in convex shapes when a person lies on the mattress to support a lumbar region of the person.
In some additional, alternative, or selectively cumulative embodiments, the at least one second bar is supported on middle portions of the plurality of the first bars, the middle portions are arranged to flex upwardly relative to ends of the plurality of first bars to support the lumbar region of the person.
In some additional, alternative, or selectively cumulative embodiments, the plurality of first bars is arranged such that first longitudinal ends of the plurality of first bars are adapted to be arranged underneath a shoulder region of the person when the person lies on the mattress, and second longitudinal ends of the plurality of first bars are adapted to be arranged underneath a hip region of the person.
In some additional, alternative, or selectively cumulative embodiments, the support structure further includes a cover to enclose the plurality of first bars and the plurality of second bars.
In some additional, alternative, or selectively cumulative embodiments, the cover includes a plurality of first sleeves configured to receive and enclose the plurality of first bars.
In some additional, alternative, or selectively cumulative embodiments, the cover includes at least one second sleeve extending substantially perpendicular to the plurality of first sleeves and configured to receive and enclose the one or more of the second bars.
In some additional, alternative, or selectively cumulative embodiments, the at least one second sleeve includes a plurality of second sleeves arrayed in the longitudinal direction and adapted to removably receive the at least one second bar.
In some additional, alternative, or selectively cumulative embodiments, one or more of plurality of first bars includes two carbon fiber strips laminated together.
In some additional, alternative, or selectively cumulative embodiments, a cross-sectional area of one or more of the plurality of first bars varies from a central/middle portion of the first bars towards ends of the first bar.
Exemplary embodiments are described below with reference to the accompanying drawings. Unless otherwise expressly stated in the drawings, the sizes, positions, etc., of components, features, elements, etc., as well as any distances therebetween, are not necessarily to scale, and may be disproportionate and/or exaggerated for clarity.
The terminology used herein is for the purpose of describing example embodiments only and is not intended to be limiting. As used herein, the singular forms “a,” “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should be recognized that the terms “comprise,” “comprises,” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. Unless otherwise specified, a range of values, when recited, includes both the upper and lower limits of the range, as well as any sub-ranges therebetween. Unless indicated otherwise, terms such as “first,” “second,” etc., are only used to distinguish one element from another. For example, one element could be termed a “first element” and similarly, another element could be termed a “second element,” or vice versa. The section headings used herein are for organizational purposes only and are not to be construed as limiting the subject matter described.
Unless indicated otherwise, the terms “about,” “thereabout,” “substantially,” etc., mean that amounts, sizes, formulations, parameters, and other quantities and characteristics are not and need not be exact, but may be approximate and/or larger or smaller, as desired, reflecting tolerances, conversion factors, rounding off, measurement error and the like, and other factors known to those of skill in the art.
Spatially relative terms, such as “right,” left,” “below,” “beneath,” “lower,” “above,” and “upper,” and the like, may be used herein for ease of description to describe one element's or feature's relationship to another element or feature, as illustrated in the drawings. It should be recognized that the spatially relative terms are intended to encompass different orientations in addition to the orientation depicted in the figures. For example, if an object in the figures is turned over, elements described as “below” or “beneath” other elements or features would then be oriented “above” the other elements or features. Thus, the term “below” can, for example, encompass both an orientation of above and below. An object may be otherwise oriented (e.g., rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein may be interpreted accordingly.
Unless clearly indicated otherwise, all connections and all operative connections may be direct or indirect. Similarly, unless clearly indicated otherwise, all connections and all operative connections may be rigid or non-rigid.
Like numbers refer to like elements throughout. Thus, the same or similar numbers may be described with reference to other drawings even if they are neither mentioned nor described in the corresponding drawing. Also, even elements that are not denoted by reference numbers may be described with reference to other drawings.
Many different forms and embodiments are possible without deviating from the spirit and teachings of this disclosure and so this disclosure should not be construed as limited to the example embodiments set forth herein. Rather, these example embodiments are provided so that this disclosure will be thorough and complete, and will convey the scope of the disclosure to those skilled in the art.
Reference in this specification to “one embodiment” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present disclosure. The appearance of the phrase “in one embodiment” in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.
Reference will now be made in detail to specific embodiments or features, examples of which are illustrated in the accompanying drawings. Generally, corresponding reference numbers will be used throughout the drawings to refer to the same or corresponding parts. Also, wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or the like parts.
Referring to
As shown, the support layer 122 is arranged/sandwiched between the base layer 120 and the top layer 124. In some embodiments, an upper surface 126 of the support layer 122 is adhesively attached to a bottom surface of the top layer 124, and a lower surface of the support layer 122 is attached to a top surface of the base layer 120. In some embodiments, the top layer 124 is softer relative to the support layer 122 and the base layer 120 is harder relative to the support layer 122. In some embodiments, one or more of the layers 122, 124 may be made of a soft foam material, for example, memory foam, latex foam, and polyurethane form. In some embodiments, the base layer 120 may be made of a foam material, for example, polyurethane form or coconut coir. In an embodiment, the base layer 120 may include a plurality of springs or coils embedded inside the layer. Although, three layers 120, 122, 124 are shown, it may be appreciated that the base layer 120 may be omitted.
The mattress 100 further includes a support structure 130 coupled to the support layer 122 and arranged proximate to the upper surface 126 of the support layer 122. In an embodiment, the support structure 130 is arranged contacting the upper surface 126 and is stitched or adhesively coupled to the upper surface 126 of the support layer 122. Alternatively, the support structure 130 may be embedded inside the foam of the support layer 122. For so doing, the support layer 122 may include suitable cut-outs or slots extending downwardly from the upper surface 126 of the support layer 122. It may be appreciated that the dimensions of the slots/cut-outs correspond to the dimensions of various elements of features of the support structure 130. The support structure 130 is configured to flex in an arch shape, for example, a convex shape, to support a lumbar portion of the person when the person lies on the mattress 100.
As shown, the support structure 130 includes a plurality of bars having a plurality of first bars 142 extending in a longitudinal direction (i.e., substantially parallel to longitudinal sides 102, 104 of the mattress 100) and arrayed in a lateral direction between the first longitudinal side 102 and the second longitudinal side 104. As shown, the first bars 142 are arranged spaced apart from each other and are disposed substantially parallel to each other. Moreover, a first longitudinal end 144 of each of the first bar 142 is arranged proximate to the first lateral side 106 such that the first longitudinal ends 144 of the first bars 142 are disposed underneath or directly below a shoulder region of the person when the person lies on the mattress 100, while a second longitudinal end 146 of each first bar 142 is arranged distally from the first lateral side 106 such that the second longitudinal ends 146 of the first bars 142 are arranged underneath or directly below a hip region of the person when the person lies on the mattress 100.
Moreover, the plurality of bars includes at least one second bar 150 disposed/arranged/extending substantially parallel to the lateral sides 106, 108 of the mattress 100 and coupled to the first bars 142. The at least one second bar 150 is located between the first longitudinal ends 144 and the second longitudinal ends 146 of the first bars 142 such that the at least one second bar 150 is arranged at a desired location underneath a lumbar region of the person when the person lies on the mattress 100. As shown in
In an embodiment, the plurality of bars 142, 150 may be carbon fiber flat bars. In some embodiments, the at least one second bar 150 is a carbon fiber bar, while the plurality of first bars 142 includes spring steel bars. Alternatively, the plurality of bars 142, 150 may be made from other suitable rigid material, such as wood, metal, alloys etc. using any other suitable manufacturing technique, such as, extrusion and casting. In an embodiment, the plurality of first bars 142 may be between 50 centimeters (cm) to 75 centimeters long and has a cross-sectional dimension of 1 cm×2 mm and the at least one second bar 150 may be 60 cm long and has a cross-sectional dimension of 2-3 millimeters (mm)×10-30 mm, preferably of 1.5 mm×15 mm. However, the length and the cross-sectional dimensions of the bars 142,150 may vary based upon the support required to the person.
Referring to
As illustrated, the support structure 130 may include a single second bar 150 and in such a case the second bar 150 is arranged inside one of the second sleeves 164, for example, the second sleeve 164a and other second sleeves 164b, 164c are empty. This facilitates removal of the second bar 150 from the second sleeve 164a and insertion of the second bar 150 in any of the other second sleeves 164b, 164c to configure/provide the lumbar support at a desired location depending upon the person preference and physiology of the person. The cover 160 enables easy coupling/attachment of the bars 142, 150 with each other and with the support layer 122. Also, as the sleeves 162, 164 are made of fabric and relatively soft material, the sleeves 162, 164 prevent abrasion and the damage to the support layer 122 due to repeated flexing and unflexing of the bars 142, 150.
In use, when the person lies on the mattress 100 ends 144, 146 of the plurality of first bars 142 extends downwards due to the compression of the mattress 100 caused by the shoulder region and the hip region of the person and the fulcrums provided by the connections of the at least one second bar 150 with the plurality of first bars 142. This additional compression of the ends 144, 146 of the first bars 142 results into an upward deflection of the middle portions of the first bars 142 and movement the at least one second bar 150 upwardly. It may be appreciated as the second bar 150 is coupled to each of the first bars 142, the first bars 142 moves in an arch shape, resulting the support structure 130 to flex in an arch shape inside similar to a natural shape of the back of the person, providing additional support to the lumbar region of the person. Additionally, due to selective insertion of the second bar 150 in the plurality of the second sleeves 134 a variation in the arch shape of the support structure 130 is achieved to facilitate a desired support to the lumbar area of the person.
In an alternative embodiment, the plurality of first bars 142 may include two strips of material, for example, two carbon fiber strips laminated together to increase the flexibility of the first bars 142 to facilitate improved deflection of the at least one second bar 150. In some embodiments, the first bars 142 may include varying cross sections (either width and/or thickness) to achieve improved flexibility. In some embodiments, the cross-sectional area (i.e., width and/or thickness) may decrease from the central/middle portion of the first bars 142 towards the ends 144, 146.
