Description

Technical Field

[0001] The proposed technology generally relates to spring compression arrangements for mattresses, and mattresses and beds incorporating such compression arrangements. Background Technology

[0002] Many different mechanisms exist in bed technology to achieve mattresses with adjustable firmness or compression levels. A relatively common mechanism utilizes a motor to apply force to one or more compression planes of the bed, thereby creating variable tension in springs arranged on or above these compression planes. If the motor presses the compression plane upwards, the springs are compressed, giving the mattress one firmness, while adjusting the compression plane downwards creates less compression in the springs, giving the mattress another firmness. Even though these known structures can adjust the firmness of the bed, they contain many mechanical parts. This makes the bed difficult to build and assemble. Some of the components used are also very fragile and therefore easily damaged, requiring repair or replacement. However, this can be very troublesome because these components are difficult to access. Therefore, there has been a need in the art to design mattresses with adjustable firmness that also overcome some of the problems in the field. The proposed technology aims to provide a mattress arrangement that at least alleviates some of the problems in this field. Summary of the Invention

[0003] The aim is to provide a spring compression arrangement for mattresses that is easy to assemble and provides a robust spring structure.

[0004] Another objective is to provide a mattress that includes this spring compression arrangement.

[0005] Another objective is to provide a bed that includes a mattress with this spring compression arrangement.

[0006] These and other objectives are achieved through embodiments of the proposed technology.

[0007] According to a first aspect, a spring compression arrangement for a mattress is provided. The spring compression arrangement includes a block made of an elastic material, the block including a first outer surface and a second outer surface positioned opposite to it. The block includes through-holes extending between the first and second outer surfaces. The arrangement also includes a plurality of springs disposed in the through-holes of the block, the springs extending in a direction from the second outer surface to the first outer surface.

[0008] According to the second aspect, a mattress is also provided, the mattress including a frame and a spring compression arrangement according to the first aspect attached to the frame.

[0009] According to the third aspect, a bed is provided that includes the mattress according to the second aspect.

The method further includes arranging a plurality of springs in the through holes of the block such that the springs extend in a direction from the second outer surface to the first outer surface.

[0011] The proposed technology enables mattresses and beds to have adjustable firmness, while also being sturdy and easy to assemble. The ease of mattress assembly, in turn, makes bed assembly and installation time-efficient.

[0022] In all the accompanying drawings, the same reference numerals are used for similar or corresponding elements.

[0023] Generally, all terms used herein are to be interpreted according to their common meaning in the relevant art, unless a different meaning is explicitly given and / or implied from the context of their use. Unless otherwise expressly stated, all references to "a / an / element, appliance, component, device, step, etc." are openly interpreted as referring to at least one instance of that element, appliance, component, device, step, etc. The steps of any method disclosed herein need not be performed in the exact order disclosed, unless a step is explicitly described as following or preceding another step and / or implied that a step must follow or precede another step. Where appropriate, any feature of any embodiment disclosed herein may be applied to any other embodiment. Similarly, any advantage of any embodiment may be applied to any other embodiment, and vice versa. Further objects, features, and advantages of the appended embodiments will become apparent from the following description.

[0024] Any directional reference, such as "upper," "top," "lower," or "above," refers to the arrangement when placed in the intended direction of use. In other words, these terms are defined when the mattress is positioned to support the body. These directions are also shown in the diagram.

[0025] To better understand the proposed technology, it may be helpful to first briefly discuss the issues associated with mattresses having adjustable firmness. Consider a mattress comprising springs embedded in fabric pockets. In their natural, unstretched state, these springs provide a natural level of compression, called the ground state level. To change the ground state level, the springs must be compressed. One particular way to achieve this compression is to provide the mattress with a spring compression device that acts on the springs to compress the cords. This can be achieved, for example, by attaching a cord or rope to one end of the spring embedded in the fabric pocket (i.e., the upper end in the vertical direction) and the other end to a movable plane arranged below the spring. By raising or lowering the movable plane, the length of the spring can be changed, thus altering the mattress's level of compression. A significant drawback of this structure is that all the springs are embedded in a fabric cover called a fabric pocket. This makes attaching individual cords or ropes to the springs very complex. Individual fabric pockets are also quite fragile; if they become entangled with the springs when they are in a low-compression state, they may tear. Tears in the fabric pockets can lead to fabric edges losing or coming loose, which can then become entangled with the springs and negatively impact their ability to compress. Uneven compression of the springs results in unbalanced compression of the mattress, reducing its comfort. The proposed technology aims to at least partially overcome the problems associated with this type of bed arrangement.

[0026] For this purpose, the spring compression arrangement 100 for the mattress 11 includes a block 1 made of an elastic material, the block including a first outer surface 12a and a second outer surface 12b positioned opposite to it. The spring compression arrangement 1 also includes a plurality of springs 2 disposed in the block 1, the springs extending in a direction from the second outer surface 12b to the first outer surface 12a.

[0027] The aforementioned arrangement provides a very robust and easy-to-install mattress compression mechanism. This arrangement is... Figure 1a and Figure 1b The spring compression arrangement is illustrated schematically. It comprises a block made of an elastic material, such as foam, i.e., a material matrix containing at least partially open air bubbles / cells, thus providing a matrix that allows for air redistribution. The block is preferably shaped as a rectangular box of elastic material. The block material is preferably selected from the group consisting of different foams, particularly polyurethane foam, latex, memory foam, gel foam, or foams having the same elastic properties as one or more of the above. The elastic material can also be a combination of the above foams. The elastic properties of the material allow for variations in the block's stiffness or density, and this feature can be used to change the level of compression of the block, thereby altering the mattress containing the spring compression arrangement. The spring compression arrangement also includes multiple springs disposed within the elastic material block. The arrangement of springs within the elastic material block is shown in the diagram. Figure 1a In mattresses, springs are positioned in a primary direction, such as vertical. The placement of springs within a block of elastic material provides an additional degree of freedom for altering the mattress's compression level; that is, the spring compression level can be based on both the compression level provided by the material in the block and the compression level achieved by the tension in the springs. The latter can be used to adjust the overall compression level achieved by the material in the block. Examples of how this adjustment of compression level can be achieved are described below. The proposed spring compression arrangement for mattresses, as disclosed herein, offers several advantages in addition to those already mentioned. The first advantage gained by using an elastic material block in conjunction with springs is that the elastic material block stabilizes the springs. The more stable placement of springs within the block compared to fabric pockets allows for greater freedom in positioning the springs within the block. It also allows for more options in the use of springs. The combination of the elastic material block and springs also creates a more pronounced difference between the hard and soft points on the mattress.

[0028] Some embodiments considered herein will now be described more fully with reference to the accompanying drawings. However, other embodiments are included within the scope of the subject matter disclosed herein, and the subject matter should not be construed as being limited to the embodiments set forth herein; rather, these embodiments are provided by way of example to convey the scope of the subject matter to those skilled in the art.

[0029] According to an embodiment of the proposed technology, a spring compression arrangement 100 is provided, wherein block 1 includes through holes 3, each through hole extending between a first outer surface 12a and a second outer surface 12b, and wherein each spring is disposed in a corresponding through hole 3.

[0030] This allows the springs to move along the direction of their corresponding through holes 3 set in the block. Figure 2a A cross-sectional view of this embodiment is provided, showing that each spring 2 is disposed in a through hole 3 arranged in an elastic material block.

[0031] According to another embodiment of the proposed technology, a spring compression arrangement 100 is provided, wherein one end 2a of at least a subset of the springs 2 protrudes a distance D above the first outer surface 12a of the block 1. This embodiment also... Figure 2a As shown in the image.

[0032] According to a specific version of the above embodiment, a spring compression arrangement 100 is provided, wherein the distance D is selected from the interval [H / 100; H / 2], where H is the height in the direction from the second outer surface 12b of the elastic material block 1 to the first outer surface 12a. Figure 5 This demonstrates how a spring extends a distance D above the surface 12a of an elastic material block 1.

[0033] exist Figure 3a In the illustrated embodiment, the spring is compressed in arrangement 100, wherein the outermost end of spring 2 is attached to wire 4. The outermost end of the spring is located at the upper end closest to the first outer surface 12a.

[0034] In a particular embodiment, the outermost end of the spring 2 is provided with a cap 18, the cap having a hook or hole for securing the wire 4 to the cap 18. This embodiment is shown in Figure 3a middle.

[0035] Specific embodiments of the proposed technology provide a spring compression arrangement 100, wherein the arrangement further includes a first plane 7 attached to block 1, the first plane 7 extending substantially parallel to the second outer surface 12b. The arrangement also includes a line 4 extending between a corresponding cap 18 and the first plane 7, one end of the line or cord attached to the corresponding cap 18 and the other end attached to the first plane 7. The arrangement further includes a second plane 6 movably arranged between the second outer surface 12b of block 1 and the first plane 7, the second plane including a plurality of holes allowing the line 4 to extend through the second plane 6. The arrangement further includes a lifting device 8 connected to the second plane 6 and configured to raise or lower the position of the second plane 6 relative to the first plane 7, thereby changing the compression level of the elastic material block 1 and the spring 2. The second plane 6 is arranged to be movable relative to the fixed first plane 7. The second plane 6 should preferably be arranged flush with the second outer surface 12b, that is, the second outer surface 12b can preferably be mounted on the second plane 6. When the second plane 6 is lifted, this will automatically ensure that the second outer surface 12b and the spring end closest to it are pressed upward, thereby ensuring that the compression levels of both the elastic material block 1 and the spring 2 change.

[0036] This embodiment provides a specific spring compression arrangement, which in Figure 4 The image shows an image embedded in a mattress. This compressed arrangement includes a block 1, which is formed as a matrix of elastic material, preferably as a box-shaped matrix of elastic material. This matrix then includes a plurality of through-holes extending from a first (e.g., upper) surface 12a to a second (e.g., lower) surface 12b. Each through-hole accommodates a spring 2, the upper end of which preferably, but not necessarily, extends above surface 12a. The upper end 2a of the spring includes a cap 18 with a hook or hole. One end of a line 4 is attached to the cap 18 using the hook or hole. The other end of the line is attached to a first plane 7. A second plane 6 is arranged between the second outer surface 12b of the block 1 and the first plane 7, in such a way that the second plane can move along a direction extending between the first plane and the outer surface 12b of the block 1, i.e., along... Figure 4 The vertical direction in the first plane 7. The second plane 7 is provided with a plurality of holes, which allow the line 4 to extend through the second plane 6 to attach to the first plane 7.

[0037] refer to Figure 4 A particular version of the described embodiment provides a spring compression arrangement 100, wherein the lifting device 8 includes an electrically or hydraulically driven lift capable of continuously raising or lowering the position of a second plane 6 relative to a first plane 7.

[0038] It has been described in detail Figure 4 The components included in the spring compression arrangement will no longer be described in detail, nor will they be used to change the compression level in the mattress. For this purpose, consider... Figure 4The spring compression arrangement is disclosed herein. In the configuration with the lowest compression level, the second plane 6 is substantially flush with the first plane 7, and preferably it is also flush with the lower surface 12b of the block 1. To change this compression level, i.e., increase the compression, the lifting device 8 is activated. The lifting device 8 is used to raise the movable second plane 6 above the surface of the first plane 7. Since the tip 2a of the spring is attached to the first plane 7, the tip 2a maintains its vertical position relative to the first plane 7. The movement of the movable plane 6 presses the lower end of the spring and the surface 12b of the block vertically upward. The spring 2 and the block 1 are pointed toward the first plane 7 by the line or rope 4, and the lifting action will press the spring and the block together, thereby changing (i.e. raising) the compression level of the mattress including the spring compression arrangement. This action can also be reversed, lowering the position of the second plane 6 by allowing the lifting device to move toward the position of the first plane 7, thereby reducing the compression level of the spring and block arrangement.

[0039] Another embodiment of the proposed technology provides a spring compression arrangement 100, wherein the spring 2 includes a helical spring or a spiral spring.

[0040] The proposed technology also provides a mattress equipped with the spring compression arrangement as described above. For this purpose, a mattress 11 is provided, which includes a frame 50 and a spring compression arrangement 100 connected to the frame 50 according to the previously described method.

[0041] The proposed technology also provides a bed 1000, which includes a mattress equipped with a spring compression arrangement as described previously.

[0042] In addition to the apparatus described above, the proposed technology also provides a method for producing a spring compression arrangement for a mattress. To this end, a method for manufacturing a spring compression arrangement 1 for a mattress 5 is disclosed. This method includes a step S1 of providing an elastic material block 1, the block including a first outer surface 12a and a second outer surface 12b arranged oppositely. The method also includes a step S2 of arranging a plurality of springs 2 in the block 1 such that the springs extend in a direction from the second outer surface 12b to the first outer surface 12a. Figure 6 This is a schematic flowchart illustrating the proposed method.

[0043] The proposed technology provides a method for producing a block of elastic material, wherein springs are arranged in through holes disposed in the block. To this end, a method is disclosed, wherein the step of providing block 1 further includes forming a plurality of through holes extending through the elastic material block 1 (i.e., from a first outer surface 12a to a second outer surface 12b arranged oppositely), and wherein the step S2 of arranging a plurality of springs 2 in block 1 includes arranging springs 2 in at least some of the formed through holes. Preferably, the through holes are formed by performing water cutting (sometimes referred to as waterjet cutting, i.e., using a water jet as a cutting tool to form through holes in block 1) on the elastic material block 1.

[0044] A specific embodiment of the proposed technology provides a method that further includes the step of attaching a wire 4 to the upper end of each spring. The length of the wire is longer than the distance between the first outer surface 12a and the oppositely arranged second outer surface 12b.

[0045] In a further preferred embodiment, the method further includes providing a cap 18 at the end of each spring 2, the cap comprising a hook or a hole. Thus, attaching a wire to the upper end of the spring is performed by utilizing the hook or hole on the cap.

[0046] This embodiment provides a version of the elastic material block 1, which can be used as follows: Figure 4 The spring compression arrangement shown is used in this method. To achieve this spring compression arrangement, the method can be supplemented by having the following steps.

[0047] - A second plane 6 is provided below the second outer surface 12b of block 1.

[0048] - A plurality of holes are formed in the second plane so that the line 4 can extend through the second plane 6;

[0049] - Attach the first plane 7 to the block 1 below the second plane 6, such that the first plane 7 extends substantially parallel to the second outer surface 12b of the block;

[0050] - By first threading the open end of wire 4 through a hole formed in the second plane, the open end is attached to the first plane 7; and

[0051] - Connect the lifting device 8 to the second plane 6 so that the lifting device can raise or lower the position of the second plane 6 relative to the first plane 7.
