Abstract

A segmented mattress or topper or segmented comfort layer consists of a cover having an upper part and a lower part which are connected by a zip fastener or otherwise, and contains sheets of a foam material divided into parts which are packed into cases, the claimed mattress being single-sided or double-sided.

Description

Segmented mattress.

A segmented mattress (hereinafter: mattress, segmented comfort layer) refers to bedding. The mattress is intended for use as a sleeping accessory, as a topper with other mattresses, sofas and as a comfort layer in mattresses, upholstered furniture and vehicle seats. Different mattress designs are known, as for example in the patents: RU2016142703A, US3846857A, US5107558A, US6256821B1, US7059001B2.

The main disadvantage of any mattress is wear due to sagging during its use.

This mainly relates to the degradation of various types of foam materials used in the manufacture of different types of mattresses.

Degradation of the comfort layer is inevitable and you have to put up with it. The owner of the mattress lies down on it every evening, in the same place as the day before. Thus, the mattress is subjected to local loads for 7-10 hours every day. In order for the mattress to last long enough, manufacturers recommend buying mattresses with increased hardness, but such mattresses are not comfortable enough, because they do not provide uniform support over the entire area of the user’s body.

In addition, for foam materials there is a time factor, since the materials that create the comfortable layer of any mattress deteriorate over time and lose elasticity even without load. Almost always, when the mattress ceases to be comfortable, its spring part, consisting of steel wire and steel springs, continues to be fully functional.

Explanation: any material intended for use in mattresses as a comfort layer will be referred to in this description as: foam rubber.

This description will not talk about other design elements of a segmented mattress, for example, such as: the type of springs used, the number of layers, the brand and composition of the internal materials used, since they can be anything suitable for a specific purpose.

In addition, there are currently so-called toppers (thin sofa mattresses) on the market, which are designed for laying on top of sofas or on top of any other mattresses.

Their main problem is the same as that of any other mattresses, because their comfort layer consists of a continuous (over the entire area of the mattress) foam rubber sheet, which, with sufficiently long use, wears out with the formation of depressions and waviness along the edges.

Also, mattresses become unusable and lose their performance properties due to contamination and damage to the outer fabric layer (cover). The problem of degradation of foam rubber or any other foam material that makes up the comfortable layer of a mattress is a big problem for all consumers. For this and other reasons described above, over 18 million mattresses are thrown into landfills every year in the United States alone.

The proposed mattress design is free of these problems. The design of the mattress is shown in the figures:

Figure 1, where 1 is the upper part of the cover, 2 is the lower part of the cover, 3 is a zipper lock (hereinafter the zipper, as well as all shown zippers, will be indicated by the number 3, regardless of their size and installation location), 4 - box ( further will be boxes of any design and shape will be indicated by the number 4), 5 - coconut coir or other material suitable for the manufacture of mattresses (hereinafter: coconut coir). On the leader is a section of a box, where 8 is foam rubber (further foam rubber of any shape and size is indicated by the number 8), 4 is a box, 5 is coconut coir.

Coconut coir (coir) is a layer of fibers covering the fruit of the coconut palm. In addition to coconut coir, the following can be used:

Synthetic felt is a dense and elastic non-woven material made from synthetic fibers. Unlike natural wool felt, it does not rot, is not affected by mold, dries quickly, and is tear-resistant.

Orto Foam is a durable artificial material based on polyester compounds.

Struttofiber consists of two parallel planes, between which there is a supporting layer with vertically arranged fibers.

Thermal felt (thermo-pressed felt) is a non-woven material consisting of natural and synthetic fibers.

Bi coconut (Bi-cocos) is a non-woven material made from natural coconut and polyester fibers.

A zipper, or simply a zipper, is a type of fastener designed to quickly connect clothing parts. Also used in bags, sporting goods, camping equipment and other items.

Textile fastener (Velcro, Velcro, Velcro tape, contact tape, burdock) is a fastener used in light industry.

Figure 2, where, 6 - Velcro fastener (hereinafter: Velcro, in the text no distinction will be made between the parts of the Velcro, since it consists of two parts. It is understood that all Velcro are always located on the correct side. Also, no distinction will be made between shapes and sizes of Velcro, as well as between the places where they are installed.Velcro installed in any place and of any size and configuration will be indicated by the number 6, markings for installing boxes - 7 (hereinafter: markings).

In this mattress design, there is toothed tape, one on the top and bottom sides of the mattress, and 6 Velcro strips. The remaining parts of the mattress, available in the figures, but not indicated by numbers, are parts of the internal structure of the mattress, which can be made of any material suitable for this purpose. In addition to zippers, Velcro, clothing snaps, clothing hooks, buttons and other accessories can be used to attach the base.

Figure 26 shows parts of a double-sided segmented mattress, where 1 is the upper part of the cover, 4 is the box, 20 is the base, 3 is the zipper, 6 is Velcro, 26 is the zipper on the bottom side of the mattress, 28 is the cover on the bottom side of the mattress, 29 is the tape. , 10 - mattress block. The callout shows an enlarged view of part of a double-sided segmented mattress, where a component of the zipper is visible - a braid with 29 teeth.

A segmented mattress (Figure 1) consists of a fabric cover consisting of the upper part of the cover 1 and the lower part of the cover 2. Moreover, the lower part of the cover 2 can consist of several layers of fabric and a denser material laid between them, which can be, for example: synthetic felt or coconut coir 5.

The upper part of the cover 1 and the lower part of the cover 2 are fastened together with a zipper 3, which can connect them along the entire perimeter of the mattress with the possibility of completely separating these parts or partially. The upper part of the cover 1 also consists of a top layer of fabric and a fabric backing (not shown), as well as a layer consisting of quilted fabric with non-woven material, for example: padding polyester (not shown).

On the inner surface of the lower part of the cover there are boxes 4 (Figures 1 and 2) made of fabric based on natural, synthetic or artificial fibers, intended for placing inside them pieces of foam rubber 8 (Figure 1; 4; 5; 12) in the form of rectangular parallelepipeds or square parallelepipeds, as well as other shapes corresponding to the shapes of the boxes. In addition, boxes can be made from non-woven materials based on natural, synthetic or artificial fibers, as well as from natural, synthetic or artificial leather. The corners of the boxes can be straight (equal to 90 degrees), rounded (Figure 7) or beveled (not shown in the figures). To give the desired shape, the component parts of the boxes can be fastened by stitching with threads, glued together with glue, or welded by heating. Also, boxes can be made from knitted fabric, using cutting, semi-regular or regular methods. Cutting method:

When using this method, the knitted fabric is cut into separate parts in accordance with the patterns of the future product, and then the parts are joined using a sewing machine.

Semi-regular way:

In this case, the knitted fabric is made in the form of coupons on a special knitting machine. The width of each coupon is equal to the width of the future product.

Regular way:

A distinctive feature of this method is that the product is knitted entirely on an automatic machine and without seams. Sometimes individual parts are knitted, which are then sewn together with a single stitch.

There are options for boxes of a trapezoidal shape with a thickened base 23 (Figure 23) and boxes with curves upward (Figure 24), also with a thickened base 23. Boxes of such shapes are installed with the base down, without a gap in relation to other boxes.

The boxes are installed according to the markings applied with paint, woven from threads, made from sewn with threads or glued ribbons or braid (7 Figure 2). Marking 7 divides the inner surface of the lower part of the cover or base 20 (Figure 15) into sections and marks the boundaries of the installation of the boxes. The dimensions of a piece of foam rubber 8, taking into account tolerances, correspond to the length, width and height of box 4, and the dimensions of rectangular (in the shape of rectangular parallelepipeds) boxes are multiples of the width and length of the mattress. For example: if the mattress measures 2.2 meters long by 1.8 meters wide (height is not taken into account), then the dimensions of the boxes will be approximately 36 centimeters by 37 centimeters, excluding the spaces between them. That is, 30 boxes should be installed on such a mattress. If the boxes or mattress have different sizes, the number of boxes will be different. In addition, boxes of different sizes can be installed in the mattress. For example: larger boxes can be installed in the middle of the mattress, and smaller ones along the edges (not shown in the figures). In addition to rectangular, the boxes can have other shapes, for example: triangular, as well as diamond-shaped, pentagonal, hexagonal (examples of box shapes are shown in Figure 18). Figure 19 shows a version of a mattress made up of triangular boxes. The mattress can consist of boxes of different shapes, for example: in the middle part of the mattress, quadrangular or pentagonal boxes can be installed, and on the edges, boxes with a different number of angles, for example: triangular. For example: Figures 20, 21, 22 show examples of mattresses made up of quadrangular and triangular boxes.

In addition, there are possible options for mattresses consisting of puzzle-shaped boxes (not shown in the figures), as well as combinations of boxes of different geometric shapes, for example: circle, oval, semicircle. Moreover, in mattresses with a combined composition of boxes, they can be presented in different sizes, for example: there may be more than one option for triangular or other boxes, for example: rectangular and triangular boxes of different sizes can be installed in one mattress. The foam rubber inside boxes of any shape always has the appropriate size and shape.

In addition, foam rubber in boxes can have vertical (not shown in the figures) or horizontal perforation (Figure 14). Moreover, these holes can be filled with more dense or less dense foam rubber or pneumatic inserts (not shown in the figures). In Figure 14, the holes are shown with dotted lines, since it is assumed that the foam rubber is in boxes. A pneumatic insert is a sealed container filled with gas made of polyethylene, rubber and other material capable of holding gas. Carbon dioxide can serve as a gaseous filler.

Also shown in Figure 12 are variants of foam rubber with a vaulted top, where option A is a box with a double arch and horizontal perforation of foam rubber, B is a variant of a box with a single arch and horizontal perforation of foam rubber, where there is a 17th hole. On the leader is a section of a box containing foam rubber with a two-vaulted top, where 4 is a box, 8 is foam rubber.

Figure 13 shows a partial cross-section of the segmented mattress showing a view of the single arch boxes without perforations. Moreover, foam rubber options with a large number of arches are possible. The boxes can be attached to the inner surface of the bottom of the case (or base 20, Figure 15) using snap buttons (not shown).

The boxes, together with the pieces of foam rubber installed in them, can be glued with glue or sewn with thread to the case, without the possibility of their separation (not shown in the figures). Such boxes are installed on a fabric base 20 (Figure 15), attached to the inner sides of the lower part of the cover 2 (Figure 1) using a zipper or Velcro, and in case of wear, parts of the boxes will be replaced with new ones, all at once, together with the base 20 (not shown in the figures).

Boxes fixed on the inner surface of the lower part of the cover 2 (Figure 2) or on the base 20 (Figure 15) using Velcro can have a zipper 3 (Figure 3) along their perimeter to ensure the possibility of opening them to replace or wash what is in them foam rubber. Figure 4 shows a design option for box 4, similar to the design of a cardboard box with flaps. This version of the box is shown in two projections, rotated 180 degrees relative to each other. This box is folded as follows: foam rubber 8 is placed inside the box, then a sash “A” is placed on top of the foam rubber, to which Velcro 6 is sewn on the outside, after which the sashes “B” and “D” are lowered, in which there are windows 9. In this case, windows 9 coincide with the Velcro 6 of sash “A” and do not overlap them. Next, sash “C” is lowered with Velcro 6 sewn to it from the bottom side. At the same time, the Velcro of sash “A” coincides with the Velcro of sash “C” through the windows of 9 sashes "B" and "D". The box is connected to the bottom of the cover 2 (figures 1 and 2) using Velcro installed on the outside of the sash "C", shown in the figure on the left in the form of a diagonal cross. There can be many options for the location of the Velcro on the bottom sides of the boxes for attaching them to the inner surface of the lower part of the cover of 2 segmented mattresses, for example: in the form of crosses, stripes, corners, etc.

Figure 6 shows a version of the box (bottom view), which has a detachable “lid” made of fabric with Velcro 6 sewn onto it on both sides. Velcro for attaching the “lid” to the main part of the body of the box 4 is shown in dotted lines.

Figure 7 shows a version of the box, where the “lid” is made attached (sewn, glued) to it on one side, where there are 6 Velcro.

Figure 16 shows a version of the box, where 3 is a zipper installed around the perimeter of its lower side, 6 is Velcro for installation on the inner surface of the lower part of the case 2 (Figure 1).

Figure 17 shows a version of the box, where 6 are Velcro, 3 are zippers installed along the diagonals of the box, the fastening parts of the bottom side of the box are limited by hole 21.

In addition to the described options for boxes containing foam rubber, a foam rubber version is possible (not shown in the figures) to which fabric is glued or welded on all sides, as well as top and bottom, to the underside of which Velcro or clothing snaps are glued or sewn for attachment to the base. That is, the fabric bonded with foam rubber acts as a box to which Velcro is attached.

The boxes can be installed on the bottom of the cover 2 close to each other or, for example: with a gap of 0.5 - 3 centimeters or more (not shown). Inside the boxes 4 in the form of rectangular parallelepipeds, rectangular parallelepipeds made of foam rubber 8 are placed. Thus (Figure 1) when the cover is unfastened, the inner part of the mattress is a horizontal surface consisting of installed side-by-side and attached to the base 20 or to the inner surface of the bottom parts of the cover 2 boxes 4 with rectangular parallelepipeds made of foam rubber placed inside them. The advantage of this mattress design is that the layer of foam material is not continuous, but is divided into many separate parts.

That is, the user lying on the mattress is not located on one or several continuous layers of foam material subject to deformation due to uneven load and, as a result, subject to uneven wear, but lies immediately on several or even several dozen separate “mattresses” of small size consisting of 8 foam rubber, packed in 4 boxes.

In addition, the fact that the boxes are fixed to the bottom of the cover 2 does not allow them to move under the influence of loads in the horizontal plane relative to other boxes, and also the fact that they are not connected to each other, allows each box to perform its function independently of the other boxes . Thus, such a segmented portion of the mattress provides distributed support for the entire area of the user's body in contact with the mattress. This can be compared to the operation of an independent car suspension, each wheel of which independently adapts to uneven ground surfaces. In this comparison, rough terrain is the surface of the human body, which also has a significant set of irregularities.

This design of the mattress, the upper part of which is connected to the lower part with a zipper 3 or Velcro and the fact that the boxes have zippers or Velcro to connect their parts and are secured with Velcro, are sewn with threads to the lower part covers, fastened with buttons, clothing snaps or Velcro, allows the user to disassemble the mattress into parts for washing, replacing worn boxes or worn foam rubber contained in them.

Also, this design allows the user to rearrange the boxes from one place to another on the inner surface of the lower part of the cover in case of wear or contamination of individual parts of the mattress, because, due to uneven load, the wear of the boxes during use of the mattress will be uneven.

That is, the user of the mattress can easily unfasten the upper part of the cover and swap worn boxes with those boxes that were less worn during the operation of the mattress, for example: move boxes from the middle of the mattress to its edges, and move boxes from the edges to the middle or replace worn boxes with new ones, along with foam rubber.

A segmented mattress can be a “topper”, a so-called sofa mattress consisting of a cover with a zipper around the perimeter and with boxes fixed inside it. This type of mattress can be a top, sewn-on, zippered or simply laid on top, unfastened part of any other spring or springless mattress.

Among other things, a comfort layer (or several layers) can be an integral part of any upholstered furniture, including: sofas, couches, sofas, armchairs, ottomans, and so on. In addition, any chairs, as well as vehicle seats (not shown in the figures), can be equipped with a segmented comfort layer.

In addition, this mattress can be equipped with massaging elements 12 and a programmable control unit 13 (Figure 9) for relaxation, or for caring for bedridden patients. The massaging element (Figure 10) is a device consisting of a housing 14, made, for example, of rubber, in the internal space of which, on its lower part, an electric coil 15 is fixed, which is an electromagnet in which a rod is placed connected to the upper, elastic part of the massaging body element with a permanent magnet 16 installed in it. The electromagnets 15 of the massaging elements are connected in a certain order to a programmable control unit 13 (Figure 9), which supplies electric current to the electromagnets.

That is, when an electric current is supplied to the electromagnets 15 of the massaging elements, a magnetic field arises which repels from them the guide cores with permanent magnets 16, installed to them with the same pole. In this case, the guide cores with permanent magnets 16 are repelled from the electromagnets 15, lifting the upper parts of the housings of the massaging elements 14 (Figure 10).

Next, the programmable control unit 13, in accordance with the program selected by the user, turns on and off the supply of electric current to individual groups of electromagnets 15 installed in the massaging elements. In this case, when some of the electromagnets are turned off, then under the influence of the user’s body weight directed downward, the massaging elements will be pressed down, decreasing in height, and when the current is applied again, they will sharply or gradually increase in height. Thus, the massaging effect will be achieved by applying and turning off electric current to the massaging elements, which, in accordance with the selected program, will increase in height when applied electric current or decrease in height under the influence of the user’s body weight when the electric current is turned off.

It is also possible to operate the massaging elements in which an electric current of variable polarity is supplied from the programmable control unit to the electromagnets. That is, an electric field is generated on the electromagnet, which, when the polarity matches, repels permanent magnets fixed with a certain pole down, and when the polarity does not match, attracts them, thereby creating vibrations in the upper parts of the massaging elements.

In addition, the massaging elements of a segmented mattress installed in boxes can have a different design (Figure 11), where 16 permanent magnets are installed without guide cores, as in the previous version, and without the possibility of entering the internal space of the electromagnet 15. In addition, the upper parts of the massaging elements can be manufactured with a container (not indicated), made of a material that ensures tightness, for example: rubber, filled with liquid or gel 24 (Figure 11). Moreover, the central areas of the shells 26 of the containers are made not connected to the tops of the massaging elements 25 to ensure a better massaging effect. In addition, such a design of the massaging element, where the top of the massaging element 25 in the center is not connected to the container shell 26, makes it possible to obtain not only vertical movements of the top of the massaging element, but also horizontal ones. That is, when the massaging element operates, vertically oriented movements of the top are produced, while the shell 26, filled with liquid or gel 24, connected in the center to the top of the massaging element 25, produces horizontal movements, similar to waves on water when the stone is immersed in water first creates a depression in the form of a funnel, but after a split second, when the funnel closes, a wave is created directed towards the center, i.e., the center of the massaging element. That is, the massaging effect is achieved not only by moving the top of the massaging element up and down, but also by wave-like movements of the liquid or gel 24 from the center to the sides and from the sides to the center. That is, massaging movements are created directed not only vertically, but also horizontally.

In addition, capsules with water or memory gel in the form of boxes (not shown) can be placed in all or part of the mattress boxes, instead of foam rubber. The boxes can also be equipped with electric or liquid heating elements to heat or cool the bed. With such a mattress design, additional equipment will be required to supply coolant or electricity to boxes equipped with heating elements (not shown in the figures).

A mattress option is also possible (Figure 15), in which several layers of boxes containing foam rubber are installed on the mattress block 10. An example with two layers of boxes will be considered: The boxes of the bottom layer 19 are attached using Velcro 6 to the base 20, which is attached along the perimeter to a multi-layer mattress with a zipper 3. Above the bottom layer of boxes there is a base 20 to which the top layer of boxes 18 is secured with Velcro 6. Moreover , the boxes of different layers can be of different sizes and shapes, i.e., the boxes of the top layer 18 can be smaller, equal or larger in size than the boxes the bottom layer 19 or for example: the boxes of the top layer 18 can be triangular, the boxes of the bottom layer 19 can be rectangular.

In addition, the user can stack several mattresses on top of each other to create a higher structure (Figure 8) consisting of several mattresses and to ensure that the mattresses do not move under load, Velcro and special pads 22 can be sewn to their covers (outer shells). The pads are sewn on the sides and ends of the mattress, tucked under it and held there also with the help of Velcro. To create a layered design, the user needs to stack one mattress on top of another and unfasten the pads from the underside of the mattress and attach them with Velcro stitched above the pads of the lower mattress. In this way, it is possible to create multilayer structures consisting of several mattresses that are securely fastened together.

In addition, Velcro 6 or buttons 11 are sewn on the sides of the “mattresses” (Figure 8) to secure the sheet. In the case of buttons, for which the sheets must have slits, and when Velcro is used, Velcro must also be sewn onto the edges of the sheets. Also, in addition to buttons, clothing hooks can be sewn onto the sheet, and clothing “ears” can be sewn onto the mattress (not shown in the figures).

Also, the upper part of the cover 1 can be attached to the lower part of the cover 2 (Figure 1) or to another mattress using Velcro or buttons and loops (not shown in the figures).

Also, among other things, figure 25 shows a variant of a double-sided segmented mattress.

The industry produces so-called double-sided mattresses, which, when used constantly, must be turned over to the other side at certain intervals. The manufacturer advises doing this to extend the life of double-sided mattresses. Thus, the variant of the segmented mattress shown in figure 25 refers to double-sided mattresses. This version of the mattress, in addition to other design features described earlier and shown in figures 1-24, has a cover of the lower part 28 on the bottom side of the mattress, attached with a zipper 3 to the mattress block 10, as well as a sewn on the bottom side of the mattress block 10, placed under the cover of the bottom parts 28, half a zipper - a braid with teeth 29. That is, when turning the mattress over, the zippers of the cover of the lower part 28 and the upper part of the cover 1 are unzipped. After this, the zipper of the fabric base 20 is unzipped, which, together or separately with boxes 4 and foam rubber 8 inside they are again fastened with the remaining half of the zipper on the base 20 to the braid with teeth 29 on the other side of the mattress. Next, the cover of the lower part 29 is fastened with a zipper to the former upper side of the mattress, and the upper part of the cover 1 is fastened to the other side, which was previously the bottom. Thus, when performing a technological flipping of a mattress, the user, every few months of use, swaps parts of the mattress by unfastening them on one side and fastening them on the other side.
