The present invention relates to a fixing device and a fixing method of the spring structure and the cushioning material for the mattress, and more particularly, by changing the buffer structure of the bed mattress, it is possible to save various work labor and work time according to the manufacture and assembly of the mattress In addition, the present invention relates to a mattress spring structure and a cushioning device and a fixing method capable of improving the mattress life and spring noise reduction effect due to increased bonding strength.

In general, a bed mattress is a rectangular parallelepiped cushioning material which is mounted on an upper side of a bed frame to provide cushioning force, and a spring structure in which coil springs are installed along the longitudinal and horizontal directions, and upper and lower cushioning materials mounted on upper and lower surfaces of the spring structure. And a side cover for sealing the upper and lower surfaces of the upper / lower cover and the side surface of the spring structure located at the outer side of the upper / lower cushion material.

That is, as shown in FIG. 6, in the process of manufacturing the bed mattress 100, the nonwoven fabric 120, the shoulder surface 130, and the cushioning material 140 are laminated on the upper and lower surfaces of the spring structure 110, respectively. Then, the upper and lower surfaces of the upper and lower cover (150, 160) and the side of the spring structure 110 is located in the outer portion of the sewing cover 170 to provide a cushioning force.

Therefore, when a bedside load is applied in a state in which a bed mattress is mounted on a bed frame (not shown), the bedside load is absorbed through the cushioning material 140 to be buffered, and at the same time, the image structure provided in the spring structure 110 is provided. The coil springs 113 provided in the lower frame members 111 and 112 are cushioned and dispersed in the lifting process.

By the way, in the manufacturing process of the bed mattress 100, the cushioning member, such as the nonwoven fabric 120 and the shoulder surface 130 or cushioning material 140 on the upper / lower side of the spring structure 110 must be laminated by sewing or sewing. Therefore, there is a problem that it is difficult to reduce the manufacturing cost by increasing the number of work and work load according to the manufacture of the bed mattress (100).

In addition, the non-woven fabric 120, the shoulder surface 130, the cushioning material 140 is the spring structure 110 because the phenomenon that the buffer member and the spring structure 110 is formed by interposing the layer layer is not coupled to the combined body is coupled or tilted to the buffer member. Partial damage of the 110 is caused to cause noise of the spring and shorten the life of the mattress.

Therefore, the present invention was invented to solve the above problems, the intermediate layer made of various interior materials such as felt (Felt), non-woven fabric and palm (polm) having a porous structure on the spring structure and then laminated in a single layer or multiple layers By foaming the cushion material, which is a foam, is allowed to bleed through the through-hole of the intermediate layer to be firmly coupled to the spring structure, increasing the coupling strength of the spring structure and the cushion material to extend the life of the mattress, while reducing the noise of the spring itself. In addition, compared to the existing process, the object of the present invention is to provide a fixing device and a fixing method of the spring structure and cushioning material for the mattress that can reduce the labor cost and work time to reduce the manufacturing cost.

Hereinafter, the features of the present invention for achieving the above object are as follows.

The present invention, in the spring structure and the cushioning device for the mattress spring structure is installed in the spring structure and the cushion member mounted on each of the upper and lower surfaces of the spring structure, the coil spring is fixed through the fixing means,

4 and 5 is a process diagram and another process diagram showing a coupling method of the spring structure for the mattress and the cushioning material according to the invention.

The present invention is to apply the foam to the cushioning material 20 of the mattress for the bed, and to foam the foam to be firmly fixed to each other with the spring structure 10, as shown in Figures 1 and 2, the mattress The spring structure 10 is installed along the longitudinal direction and the coil springs 11 are fixed to each other by the helical coil 12 or not fixed to each other by the helical coil 12, and the upper and lower surfaces of the spring structure 10 Cushion material 20 mounted on each, the intermediate layer 30 in the form of a single layer or a plurality of sheets (sheet) between the spring structure 10 and the cushion member 20, the spring structure 10 and the intermediate layer ( 30 is comprised between the mesh 40 and a cover member (not shown) wrapped around the circumferential surface of the cushioning material 20.

The cushioning material 20 is a polyurethane foam, which is to be foamed while being cured. When the polyol and isocyanate are mixed, the cushioning material 20 is cured with a crosslinking reaction that sticks to each other. Materials are possible, and foams made of soft materials are all possible. In particular, memory foam is also possible.

The intermediate layer 30 is formed of a single layer or multiple layers of sheets having a predetermined thickness made of various interior materials such as felt, nonwoven fabric or palm, and includes a plurality of through holes arranged at regular intervals ( 31) is formed.

The through hole 31 has a function of allowing the foam member 21 of the foam to penetrate through the foam member 20 and to stick to the coil spring 11 of the spring structure 10 when the cushion member 20 is foamed. Done.

At this time, the through-hole 31 is formed throughout the mattress, which is to ensure that the coupling between the spring structure 10 and the cushioning material 20 as a whole is made firm.

In particular, the foam 21 of the foam penetrates through the through hole 31, and then sticks to the coil spring 11 of the spring structure 10 or the helical coil 12 at the bottom to solidify. By preventing the occurrence of cracks through the fatigue load accumulated in the helical coil 12 to extend the life of the mattress interior material and the mattress, to reduce the noise of the spring itself.

On the other hand, in the embodiment of the present invention, although the application portion of the foam is located on the upper and lower sides, by applying the foam to the side configuration, it is preferable to be able to act as a buffer against the impact from the outside.

As shown in FIG. 2, in the preferred embodiment of the present invention, the through hole 31 has an array structure in which holes are continuously repeated at equal intervals in the vertical and horizontal directions.

Here, the through hole 31 is a shape in which the foam 21 of the foam to be described later easily exits, and any shape and arrangement as long as it is an arrangement structure for increasing the bonding strength between the spring structure 10 and the cushioning material 20. It may be made of a structure.

On the other hand, the mesh 40 is composed of a string (string) of the net form at regular intervals, which is the foam 21 is attached to the string to increase the fixing, and with the spring structure 10 Not only functions to increase the coupling performance, but also functions to distribute and cushion the sleeper's load.

In the mattress assembly process, the mesh 40 is laminated on the cushioning material 20 in a state of being integrally assembled to the spring structure 10 together with the intermediate layer 30, or to be laminated on the intermediate layer 30 separately stacked. have.

The mattress for a bed configured as described above is configured to extrude and solidify a foam, which is a cushion material 20, through a through hole 31 formed in the intermediate layer 30, so that the spring structure 10 and the cushion material 20 are firmly coupled to each other.

Here, the coupling configuration for the foam 21 between the spring structure 10 and the cushioning material 20 can be applied to both the upper and lower sides, as well as the upper and lower surfaces of the upper and lower surfaces.

Hereinafter, the assembly process of the mattress according to the present invention will be described with reference to the process diagram shown in FIG. 4.

First, the foam, which is the cushion material 20, is introduced into the lower mold of the mattress shape, and the intermediate layer 30 and the mesh 40 having the through-holes 31 disposed thereon are sequentially stacked thereon at regular intervals.

At this time, the foam is gradually foamed, it is preferable to quickly laminate the laminated composition (intermediate layer, mesh, spring structure) before the foam is completely foamed.

In a state in which the spring structure 10 is stacked on the mesh 40, while a predetermined time (about 15 minutes) has elapsed, the foam is continuously in a foaming state, and the foam 21 which proceeds with foaming is It penetrates through the through hole 31 of the intermediate layer 30 and adheres to the spring structure 10.

Here, unlike FIG. 4 which separately stacks the spring structure 10, the intermediate layer 30, and the mesh 40, FIG. 5 shows the intermediate layer 30 and the mesh 40 at the bottom of the spring structure 10. In a state where it is firmly integrally assembled, it is a process of laminating it on the cushioning material 20.

On the other hand, when foaming the foam 21, in a state where the laminated structure is firmly fixed, the foam 21 covers the upper mold so that the foam 21 penetrates through the through hole 31 of the intermediate layer 30, It is preferable to fix it.

This is because when the foam 21 of the foam is not subjected to the resistance of the laminated component, the volume increases as a whole, and the foam 21 does not exit the through hole 31.

On the other hand, when the mesh 40 is provided, the coupling performance is improved to not only maximize the coupling force between the spring structure 10 and the foam material, but also the load of the sleeper is distributed / absorbed to improve the cushioning function.

As such, the present invention, the spring structure 10 and the cushioning material 20 is fixed to each other without a separate fixing device, so that compared to the existing process, the strength of the mattress is extended to increase the mating strength, foam 21 is coiled The solidification of the spring 11 or the helical coil 12 reduces the noise of the coil spring 11 itself, and reduces the possibility of cracking of the helical coil 12, thereby increasing the life of the interior material and simplifying the assembly process. do.

As described above, according to the fixing device and the fixing method of the spring assembly for the mattress and the cushioning material according to the present invention, by increasing the coupling strength of the spring structure and the cushioning material to extend the life of the mattress, compared to the existing process, The effect is to reduce the manufacturing time by reducing the working time.

In particular, the foam of the foam forming the cushion material is combined with the helical coil or coil spring has the effect of reducing the spring itself noise.
