Description

Segmented mattress (hereinafter: mattress) refers to bedding. The mattress is intended for application with sofas, and also together with other mattresses of any type. Different designs of mattresses are known, such as in patents: RU 2016142703 A, US3846857A, US 5107558 A, US 6256821 B1, US 7059001 B2.

The main disadvantage of any mattress is wear in the form of dents during its operation.

This mainly refers 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 we 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 serve for a long time, manufacturers recommend buying mattresses of increased rigidity, but such mattresses are not comfortable enough, because. do not provide uniform support over the entire area of the user's body.

In addition, for foam materials there is a time factor, because. materials that create a 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 in a fully functional state.

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

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

Their main problem is the same as with any other mattresses, because. their comfortable layer, consisting of a continuous (over the entire area of the mattress) foam sheet, which wears out with the formation of cavities and waviness along the edges with a sufficiently long operation.

Mattresses also become unusable and lose their operational 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 each year in the US alone.

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

Synthetic felt is a dense and resilient 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. Coconut coir (coir) is a layer consisting of fibers covering the fruits of the coconut palm.

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

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

Besides coconut coir or synthetic felt, other material with suitable properties can be used.

Fig. 22, which shows an example of a mattress made of rectangular and triangular boxes, where: rectangular boxes are located in the middle of the mattress, and triangular on four sides along the periphery.

Fig. 23, which shows a trapezoidal box with a thickened base 23.

Fig. 24, which shows the box having a rounding upwards from the base 23.

The segmented mattress (Fig. 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 5 or coconut coir 5.

The upper part of the cover 1 and the lower part of the cover 2 are fastened together by a zipper 3, which can connect them around 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 a quilted fabric with a non-woven material, for example: synthetic winterizer (not shown).

On the inner surface of the lower part of the cover there are boxes 4 (Fig. 1 and 2) made of fabric based on natural, synthetic or artificial fibers, designed to place inside them pieces of foam rubber 8 (Fig. 1; 4; 5; 12) in the form 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 (Fig. 7) or beveled (not shown in the figures). To give the desired shape, the components of the boxes can be fastened together by stitching with threads, glued together with glue, welded from heat. Also, the boxes can be made from knitted fabric, cut, semi-regular or regular.

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 connected 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 at the same time without seams. Sometimes separate parts are knitted, which are then sewn together with a single stitch.

There are options for trapezoid-shaped boxes with a thickened base 23 (Fig. 23) and boxes with rounded upwards (Fig. 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, sewn with threads or glued tapes or braids (7 Fig. 2). Marking 7 divides the inner surface of the lower part of the cover or base 20 (Fig. 15) into sections and marks the boundaries of the boxes. The dimensions of the piece of foam rubber 8, taking into account tolerances, correspond to the length, width and height of the box 4, and the dimensions of the rectangular (in the form 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 gaps between them. That is, 30 boxes should be installed on such a mattress. In the event that the boxes or the mattress will have other 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 another shape, for example: triangular, as well as rhombic, pentagonal, hexagonal (examples of box shapes are shown in Fig. 18). On FIG. 19 shows a variant 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, square or pentagonal boxes can be installed, and on the edges, boxes with a different number of corners, for example: triangular. For example: in Fig. 20, 21, 22 show examples of mattresses made up of quadrangular and triangular boxes.

In addition, there are options for mattresses consisting of boxes in the form of puzzles (not shown in the figures), as well as combinations of boxes of different geometric shapes, for example: a circle, an oval, a 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 version of triangular or other boxes, for example: rectangular and triangular boxes of different sizes can be installed in one mattress. Foam rubber located inside the boxes of any shape always has the appropriate size and shape.

In addition, boxed foam may have vertical (not shown in the figures) or horizontal perforations (Figure 14). Moreover, these holes can be filled with denser or less dense foam rubber or pneumatic inserts (not shown in the figures). On FIG. 14 holes are shown in dotted lines, because it is understood that the foam rubber is in boxes. Pneumatic inserts are sealed containers filled with gas made of polyethylene, rubber and other materials capable of holding gas. The gaseous filler can be carbon dioxide.

Also in FIG. 12 shows variants of foam rubber with an arched 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 17 is a hole. On the callout is a section of a box with foam rubber in it with two vaulted tops, where 4 is a box, 8 is foam rubber.

On FIG. 13 shows a segmented mattress in partial section, showing a view of single vault boxes without perforations. Moreover, options for foam rubber with a large number of arches are possible. The boxes can be attached to the inside surface of the bottom of the case (or base 20, Fig. 15) using snap buttons (not shown).

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

Boxes fixed on the inner surface of the lower part of the cover 2 (Fig. 2) or on the base 20 (Fig. 15) with Velcro can have a zipper 3 around their perimeter (Fig. 3), to enable them to be opened for replacement or washing the foam rubber in them. In FIG. 4 shows a variant of the construction of the box 4, which is similar to the construction of a cardboard box with flaps. This version of the box is shown in two projections rotated relative to each other by 180 degrees. This box is folded as follows: foam rubber 8 is placed inside the box, then flap A is placed on top of the foam rubber, to which Velcro 6 is sewn from the outside, after which flaps B and D are lowered, in which there are windows 9. At the same time, windows 9 coincide with Velcro 6 sashes A and do not overlap them. Next, the sash C is lowered with Velcro 6 sewn to it from the bottom side. In this case, the Velcro of the sash A coincides with the Velcro of the sash C through the windows 9 of the sashes B and D. The box is attached to the lower part of the cover 2 (Fig. 1 and 2) using Velcro installed on the outer side of the leaf C, shown in the figure on the left in the form of a diagonal cross. There can be many variations of Velcro arrangement on the undersides of the boxes for attaching them to the inner surface of the lower part of the cover 2 of the segmented mattresses, for example: in the form of crosses, stripes, corners, etc.

In FIG. Figure 6 shows a variant of the box (bottom view) with a detachable lid made of fabric with Velcro 6 sewn on it on both sides.

On FIG. 7 shows a variant of the box, where the lid is attached (sewn, glued) to it on one side, where 6 are Velcro.

On FIG. 16 shows a variant of the box, where 3 - a zipper is installed along the perimeter of its lower side, 6 - Velcro for installation on the inner surface of the lower part of the cover 2 (Fig. 1).

In FIG. 17 shows a variant of the box, where 6 - Velcro, 3 - zippers installed diagonally on the box, fastening parts of the bottom side of the box are limited by hole 21.

In addition to the described variants of boxes containing foam rubber, a foam rubber variant (not shown in the figures) is possible, to which a fabric is glued or welded on all sides, as well as on top and bottom, to the underside of which Velcro or clothing buttons are glued or sewn to attach to the base. Those. fabric fastened 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 cm or more (not shown). Inside boxes 4 in the form of rectangular parallelepipeds, rectangular parallelepipeds of foam rubber 8 are placed. the lower part of the cover 2 of boxes 4 with rectangular parallelepipeds made of foam rubber placed inside them. The advantage of this mattress design is that the foam layer is not continuous, but is divided into many separate parts.

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

In addition, the fact that the boxes are fixed on the bottom of the cover 2 does not allow them to move under the action of loads in a horizontal plane relative to other boxes, and also that they are not interconnected, allows each box to perform its function independently of other boxes. . Such a 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 fastened with Velcro, sewn with threads to the bottom of the cover, fastened with buttons, clothes buttons or Velcro allows the user to disassemble the mattress into parts for washing, replacing worn-out boxes or worn-out foam rubber located 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 the uneven load, the wear of the boxes during the use of the mattress will be uneven.

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

A segmented mattress can be a topper, the so-called sofa mattress, consisting of a cover with a zipper around the perimeter and with boxes fixed inside it. Such a mattress can be top, sewn on, fastened with a zipper, or simply laid on top, not a fastened part of any other spring or springless mattress.

In addition, this mattress can be equipped with massaging elements 12 and a programmable control unit 13 (Fig. 9) for relaxation, or for the care of bedridden patients. The massaging element (Fig. 10) is a device consisting of a housing 14, made of rubber, in the inner 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 housing a massaging element with a permanent magnet 16 installed in it. Electromagnets 15 of the massaging elements are connected in a certain order to a programmable control unit 13 (Fig. 9), which supplies electric current to the electromagnets.

That is, when an electric current is applied to the electromagnets 15 of the massaging elements, a magnetic field arises, which repels from them the guiding 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 bodies of the massaging elements 14 (Fig. 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 part of the electromagnets is turned off, then under the influence of the user's body mass directed downwards, 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 disconnecting electric current to the massaging elements, which, in accordance with the selected program, will increase in height when the electric current is applied or decrease in height under the influence of the user's body weight.

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

In addition, massaging elements of a segmented mattress installed in boxes can have a different design (Fig. 11), where 16 permanent magnets are installed without guiding cores, as in the previous version, and without the possibility of entering the interior of the electromagnet 15. In addition, the upper parts of the massaging elements can be made with a container (not indicated), made of a material that ensures tightness, for example: rubber, filled with liquid or gel 24 (Fig. 11). Moreover, the central regions of the shells 26 of the containers are not connected to the tops of the massaging elements 25 to provide 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 shell 26 of the container, allows you to get not only vertical movements of the top of the massaging element, but also horizontal ones. Those. during the operation of the massaging element, vertically oriented movements of the top are made, while the shell 26, filled with liquid or gel 24, connected in the center with the top of the massaging element 25, produces horizontal movements, like waves on water, when the stone, plunging into the water, first creates a depression in in the form of a funnel, but after a fraction of a second, when the funnel closes, a wave is created directed towards the center, i.e. the center of the massaging element. Those. 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. Those. 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. Also, the boxes can be equipped with electric or liquid heating elements for heating or cooling the bed. With this design of the mattress, additional equipment will be required to supply the coolant or electricity to the boxes equipped with heating elements (not shown in the figures).

A variant of the mattress (FIG. 15) is also possible, in which several layers of boxes containing foam rubber are installed on the multilayer mattress 10. An example with two layers of boxes will be considered: The boxes of the lower layer 19 are attached with Velcro 6 to the base 20, which is attached to the multilayer mattress along the perimeter with a zipper 3. Above the lower layer of the boxes is the base 20, to which the upper layer of the boxes 18 is fastened with Velcro 6. When than, 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 of the bottom layer 19 or for example: the boxes of the top layer 18 can be triangular, the boxes of the bottom layer 19 are rectangular.

In addition, the user can stack several mattresses one on top of the other to create a higher structure (Fig. 8) consisting of several mattresses and in order for the mattresses not to move under loads, Velcro and special linings 22 can be sewn to their covers (outer shells). Pads are sewn on the side and end sides of the mattress, tucked under it and held there also with Velcro. In order to create a layered structure, 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 sewn over the pads of the bottom mattress. Thus, it is possible to create multilayer structures consisting of several mattresses that are securely fastened together.

In addition, Velcro 6 or buttons 11 (Fig. 8) are sewn on the sides of the mattresses 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 on the edges of the sheets. Also, in addition to buttons, clothes hooks can be sewn on the sheet, and clothes ears can be sewn on the mattress (not shown in the figures).

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