The present invention relates to a bed mattress using a permeable reinforcing material and a foam, and more particularly, permeable reinforcing material is laid on the upper and lower parts of the spring assembly, which is one of the frame configurations of the bed mattress, and foamed after the foam is placed on the permeable reinforcing material. The present invention relates to a mattress for a bed using a permeable reinforcement and a foam, in which a foam is expanded through a microhole and / or a foam enlargement hole of a permeable reinforcement, so that the spring assembly and the foam may be integrated.

In general, a bed mattress is a means mounted on the bed frame to provide cushioning and cushioning force, which is basically a spring assembly, an intermediate member laminated on the upper and lower surfaces of the spring assembly, and an edge former attached to the circumferential surface of the spring assembly. And, it comprises a cover member and the like surrounding the surface of the intermediate member and the edge former.

Looking briefly with reference to Figure 13 attached to a conventional mattress manufacturing method as follows.

First, a spring assembly 10 composed of a spring 12 arranged at equal intervals over an area of a mattress and a helical coil 14 for binding the spring 12 is provided.

Subsequently, an edge former 30 is inserted into and attached to the circumferential surface of the spring assembly 10.

Next, as the intermediate member 32 on the upper and lower surfaces of the spring assembly 10, a plurality of cushioning means including felt and nonwoven fabric are successively stacked.

Finally, the upper and lower surfaces and the circumferential surface of the intermediate member 32 and the outer surface of the edge former 30 and the like are covered with the cover 28, and then the seam of the cover 28 is sealed by suture means.

Therefore, the load applied to the mattress when the user is sleeping is absorbed and buffered by the cushioning force of the intermediate member and the buffering force of the spring, so that the user feels convenience and comfort.

However, such a conventional mattress structure has a disadvantage in that the manufacturing process is complicated and various processes are required, which leads to high manufacturing cost and poor workability.

In other words, the conventional mattress manufactured by the above process is laminated with a plurality of intermediate members such as felt and non-woven fabric on the upper and lower surfaces of the spring assembly, and inserts an edge former at the periphery of the spring assembly. Since it is manufactured after the production cost and labor costs increase, the production speed is slow, there is a problem that unit productivity falls.

In particular, due to the load applied during the use of the mattress or due to the aging and wear of the spring due to the long time use of the mattress, noise during use (for example, contact noise between the springs or a squeaking sound when the spring is compressed) is generated. There is a problem.

The present invention was developed in view of the above problems, the permeable reinforcing material is laid over the upper and lower parts of the spring assembly for the mattress, and the foam is permeable through a simple process of placing the foam on the surface of the permeable reinforcing material and then foaming The purpose of the present invention is to provide a mattress for a bed using a permeable reinforcement and a foam that allows the spring assembly and the foam to be integrated and manufactured while at the same time extending through the fine holes of the reinforcement.

In addition, another object of the present invention is to penetrate through the expansion hole in the permeable reinforcing material in the horizontal and vertical direction at equal intervals, so that the foaming degree of the foam is further expanded through this expansion hole, so through the expansion hole By enclosing the engagement portion of the spring assembly and the engagement ring and / or the joint or portion between the spring and the spring in the expanded foam, it is possible to further increase the coupling force between the spring assembly comprising the spring and the foam.

Further, another object of the present invention, in addition to the structure to form a foam on the top and bottom of the spring assembly, the side foaming to the side circumference of the spring assembly further progress, so that the side foam to the side circumference of the spring assembly integrally It is to provide a mattress structure of a further formed structure.

In order to achieve the object of the present invention, the existing process of stacking and attaching a plurality of intermediate members such as felt and nonwoven fabric on the upper and lower surfaces of the spring assembly, and the process of inserting an edge former around the spring assembly, may be excluded. It is possible to reduce the manufacturing cost and labor costs, and improve the unit productivity. In particular, through the process of foaming the foam using a permeable reinforcement material, it provides excellent bonding force between the spring assembly and the foam, and also makes contact noise between the springs. This can be easily prevented from occurring.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 6 and 7 to 12 show the same foam structure, but show examples of applying different spring assemblies, and the spring assemblies shown in each of the drawings show the foam structure of the present invention. Only one example for explaining the process, it is a matter of course that the foaming process can be made by applying various types of spring assembly.

1 and 7 are a mattress for bed using a permeable reinforcement and foam according to the present invention, the lower surface is a perspective view showing the state of foaming completed, the upper surface is a state before foaming, Figures 2a and 2b, 8a and 8b 3 is a cross-sectional view illustrating a method of manufacturing a mattress for a bed using a permeable reinforcement and a foam according to the present invention, and FIGS. 3 and 9 are cross-sectional views illustrating an example in which two layers of a permeable reinforcement are applied.

The present invention is to provide a bed mattress with excellent durability even by a simple process of integrally forming the foam by the permeable reinforcing material on the upper and lower surfaces of the spring assembly, in particular the fine hole and / or expanded expansion hole formed in the permeable reinforcing material The expansion of the foam through the spring assembly through the expansion, thereby providing an excellent coupling force between the spring assembly and the foam, while the main point is to prevent the occurrence of noise.

As described above, the spring assembly 10 for the mattress is a plurality of springs 12 arranged at equal intervals along the horizontal and longitudinal direction over an area substantially equal to the area of the mattress, and each adjacent spring 12 It consists of a binding ring 14 in the form of a long helical coil which is a means for binding.

More specifically, the upper end and the lower end of the spring 12 are connected to each other adjacent to the spring 12, and the portion extending to the spring 12 will be referred to as a joint 18.

Laminate one or more layers (two or more) of permeable reinforcement 20 over the upper and lower surfaces of the spring assembly 10 having such a structure, and then transmit the permeable reinforcement 20 to the spring assembly 10. ) Is fixed using the Hog Ringer method (a method of shooting a circular ring-shaped piece with an air gun), and in addition to the Hog Ringer method, the permeable reinforcing material may be attached by various methods such as an adhesive.

The permeable reinforcing material 20 is a mesh-like structure in which a plurality of fine holes 21 penetrate in the horizontal and vertical directions, as described later, is embedded in the foam 24 to serve as a framework.

The permeable reinforcement 20 embedded in the foam 24 to serve as a skeleton may be applied in one or two layers in consideration of the thickness of the foam 24, and of course, may be applied in more layers. to be.

In particular, the permeable reinforcing material 20 is formed through the expansion hole 22 in the form of a circular hole at equal intervals, for example, the predetermined of the permeable reinforcing material 20 having the micro-holes 21 in the horizontal and vertical directions The area is cut in a circular shape at once and penetrates into the foam expansion hole 22.

Therefore, when the foam 24 is disposed on the outer surface of the permeable reinforcing material 20 and foaming proceeds, the permeable reinforcing material 20 is embedded in the foamed foam 24 to serve as a frame, and the spring 10 A binding ring 14 for binding the upper end and / or the lower end and the spring 10 is also embedded in the foam 24.

At the same time, the foaming of the foam 24 is further convexly expanded toward the spring assembly 10 through the foaming expansion hole 22 of the permeable reinforcing material 20.

On the other hand, as shown in Figure 5 and 10, when the permeable reinforcing material 20 is used that the foam expansion hole 22 is not formed, that is, the permeable reinforcing material 20 with only the fine hole 21 is used Even when used, the upper and lower foams 24 can be formed. In this case, since the foaming proceeds through the microholes 21, the height of the foams 24 passing through the microholes 21 is maintained evenly, but finely. The foam thickness passing through the hole 21 is not large.

At this time, the permeable reinforcing material 20 is preferably applied to any one selected from fine mesh or nonwoven fabric, and when the permeable reinforcing material 20 is a fine mesh, the size of the fine holes 21 is 1 to 30 x 1 to 30 mm. The reason for this is that the foam 24 does not pass properly during foaming if it is 1 mm × 1 mm or smaller, and the foam 24 passes too large when foaming if it is 30 mm × 30 mm or larger.

In addition, the size of the foam expansion hole 22 of the permeable reinforcing material 20 is preferably from 3 to 80mm in diameter, the reason is that the area of the foam 24 passing through the foam expansion hole 22 is less than 3mm, but the foam is small If the height of the 24 is too high and the foam area through the foam expansion hole 22 is increased if it is 80 mm or more, the phenomenon of spreading laterally occurs as the height of the foam 24 decreases.

In particular, the size of the foam expansion hole 22 of the permeable reinforcing material is more preferably in the range of 25 to 35mm diameter.

Of course, the expansion enlargement hole 22 is formed larger than the size of the micro holes 21 and used. For example, when the size of the micro holes 21 is 1 mm × 1 mm, the application thickness of the foam 24 is increased. In consideration of the expansion hole 22 is selected in the range of 2mm ~ 80mm diameter, if the size of the fine hole is 10mm × 10mm size also considering the application thickness of the foam 24, the expansion hole 22 is 11mm ~ 80mm If the size of the fine hole 21 is 30mm x 30mm, it may be selected and applied in the range of 31mm to 80mm diameter expansion expansion hole 22 in consideration of the application thickness of the foam 24.

This is just described as an example, when applying the size of the expansion magnifying hole 22 is applied larger than the size of the fine hole 21, in consideration of the application thickness of the foam 24 and the fine hole 21 and foaming The size of the enlargement hole 22 is selected and applied.

In particular, the foam expansion hole 22 of the permeable reinforcing material 20 is preferably formed to penetrate at a position coinciding with the engagement portion between each spring 12 and the engagement ring 14 of the spring assembly 10, more Preferably, the expansion-expansion hole 22 is further formed at a position coinciding with the joint 18 between the springs 12 of the spring assembly 10 or a position between the spring 12 and the spring 12. .

The reason is that through the expansion hole 22, the binding portion between the spring 12 and the engagement ring 14 and the joint 18 between the adjacent spring 12, between the spring 12 and the spring 12 By causing the foaming of the foam 24 to proceed further convexly to the position, the binding part between the spring 12 and the engagement ring 14 and the joint 18 between the spring 12, the spring 12 and the spring ( 12) To increase the binding force between the parts.

Thus, as shown in FIG. 2A attached, expansion foam may be formed at the portion of the binding ring 14 of the spring assembly 10, or as shown in FIG. 2B, the binding ring of the spring assembly 10 may be 14) In addition to the part, expansion foaming can also be made at the position of the joint 18, the part between the spring 12 and the spring 12.

Here, it will be described in more detail with reference to Figures 2a, 2b and 8a, 8b attached to the manufacturing method of the bed mattress using the foam according to the present invention.

First, it has a spring assembly 10 composed of a plurality of springs 12 arranged in the horizontal and longitudinal directions, and a binding ring 14 which binds these springs 12.

Subsequently, one or more layers (two or more) of permeable reinforcements 20 are arranged over the top surface of the spring assembly 10 to fix the hog ringer method (a circular ring-shaped piece by shooting with an air gun). Method).

Of course, as described above, in addition to the Hogringer method, it can be attached by various methods such as a method of attaching the permeable reinforcing material with an adhesive.

Next, as the foaming process of the foam 24 proceeds with respect to the outer surface of the permeable reinforcing material 20, the foam 24 passes through the fine holes 21 of the permeable reinforcing material 20 to be foamed inwardly, The permeable reinforcement 20 is embedded for framing within the foam 24 while the top of the spring 12 is embedded in the foam 24, resulting in a spring 12 of the foam 24 and the spring assembly 10. This unites with each other.

At the same time, a portion of the foam 24 is further expanded and convexly foamed toward the spring assembly 10 through the foam expansion hole 22 of the permeable reinforcement 20.

Accordingly, the spring 12 of the spring assembly 10 and the portion of the binding ring 14 which binds the spring 12 are embedded in the foam 24 convexly extended toward the spring assembly 10, and The joints 18 between the springs 12 are also inherent, so that the foam 24 causes the springs 12 and the engagement ring 14 to be part of the joints 18 or springs 12 of the springs 12. The binding force on the portion between the and the spring 12 is further increased.

Similarly, by arranging and fixing the one or more layers (two or more) of the permeable reinforcing material 20 over the lower surface of the spring assembly 10, and then subjected to the same foaming process, the spring Foam 24 is also integrally formed in the lower part of the assembly 10, the bed 24 is formed integrally with the foam 24 on the upper and lower surfaces of the spring assembly 10 as shown in the last view of Figures 2a, 2b and 8a, 8b It will be made into a mattress product.

In another embodiment, the foam 24 may optionally be foamed on only one side of the top and bottom surfaces of the spring assembly 10.

Meanwhile, referring to FIG. 8B, expansion foam of the foam 24 is also formed between the spring 12 and the spring 12 in addition to the binding ring 14 portion of the spring assembly 10. The bonding force of the foam 24 can be further increased.

Here, the foaming process for the side circumference in addition to the foaming process for the top and bottom of the spring assembly will be described.

4 and 10 are cross-sectional views illustrating a state in which a side foam is formed besides upper and lower foams as a mattress structure for a bed using a permeable reinforcement and a foam according to the present invention.

To describe the side foaming process, first, the nonwoven fabric 26 is padded along the side circumference of the spring assembly 10 before the foaming process for the upper and lower portions of the spring assembly 10 is performed. Is fixed by the Hogringer method.

Subsequently, the foaming process is performed on the upper and lower portions of the spring assembly 10 as described above, and then the side foaming process is performed.

That is, the non-woven fabric is fixed to the spring assembly 10 of the foaming device (not shown), the foam 24 is injected along the side circumference of the spring assembly 10, and after the foaming is completed to demould Then, the side foaming process in which the foam 24 is further integrally formed with respect to the side circumference of the spring assembly 10 is completed.

Meanwhile, as shown in FIGS. 6 and 12, the edge former 30 is inserted and attached along the side circumference of the spring assembly 10 without side foaming of the spring assembly 10. The upper and lower foaming process of the spring assembly 10 as described above may be made.

As seen above, according to the mattress for bed and the manufacturing method using the permeable reinforcement and foam according to the present invention, the permeable reinforcement having a fine hole and / or a plurality of foam expansion hole in the upper and lower parts of the mattress spring assembly Through the simple process of placing and foaming the foam on the surface of the permeable reinforcement, the permeable reinforcement is embedded in the foam and at the same time, the foaming degree of the foam is further expanded through the microholes and / or the foam expansion hole of the permeable reinforcement. By enclosing the binding part of the binding ring and / or the joint or the part between the spring and the spring, it is possible to provide a good coupling force between the spring assembly and the foam.

In addition, it is possible to eliminate a number of work processes, such as the step of laminating and attaching a plurality of intermediate members such as felt and nonwoven fabric on the upper and lower surfaces of the spring assembly for mattresses, and the process of combining these intermediate members, thereby reducing the manufacturing cost and labor costs The unit productivity can be improved at the same time.

In particular, the present invention has a structure that the foam wraps around the spring and the binding ring connecting the spring, the noise generated by the friction ring that connects the spring and the spring by the load applied when using the mattress in the foam Absorption can suppress the generation of noise.
