Spring structure for mattress {SPRING STRUCTURE FOR MATTRESS}

The present invention relates to a spring structure for a mattress, and more particularly, to provide an appropriate cushioning force according to the magnitude of the external force applied to the mattress, to improve comfort and comfort, and to prevent contact noise from occurring during contraction and expansion of the spring. And, it relates to a spring structure for the mattress to improve the cushioning against the external force applied to the mattress and to prevent the sudden contraction of the spring to improve the durability.

In general, a mattress installed in a bed or the like is composed of a spring assembly, a cushioning member provided on the upper and lower surfaces of the spring assembly, an edge former installed on a circumferential surface of the spring assembly, and a cover member covering the spring assembly as a whole.

The spring assembly consists of a spring that is evenly distributed over the entire area of the mattress and a helical coil that binds the springs in a key configuration for providing a cushioning force of the mattress.

Figure 1a and Figure 1b is a perspective view of a spring for a conventional mattress, as shown in the spring is a spring body portion formed by winding a steel wire to be located in the central portion, extending in the form of winding around the top of the spring body portion, The upper spring part formed, and the lower spring part extended and formed in the form wound flat on the lower end of the spring body part, are comprised.

The spring body portion is formed in such a way that the outer diameter of the center portion is small and the outer diameter thereof increases in the vertical direction, and the upper spring portion and the lower spring portion are fixed in such a manner that they are twisted with each other at the ends of the spring body portion.

The above-described conventional spring provides cushioning force while repeatedly contracting and expanding by the load applied to the mattress. When a large load is applied in the process of applying the load, the upper spring portion and the spring body portion contact each other and the lower spring portion Since the main body and the spring body contact each other, as well as the steel wire forming the spring is in contact with the disadvantage that severe noise is generated.

Accordingly, various techniques for solving the problems of the conventional spring are disclosed. For example, Korean Patent Registration No. 10-0717548 discloses a spring structure for the bed mattress to prevent noise by improving the connection structure connecting the spring.

Patent No. 10-0717548 is shown in Figure 2, the coil spring body spring 10, and the upper and lower springs 16, which are wound around the top and bottom of the body spring 10, 18), an exposed circuit spring 20 integrally formed above the upper spring 16, and a connecting end 24 which connects the upper spring 16 and the exposed circuit spring 20 integrally with each other. The first contact preventing end 30 is formed at the end 24.

The spring structure for the bed mattress is the body spring 10 of the first contact preventing end 30 is located when the exposure line spring 20 is compressed by the load applied as the load is applied to the bed mattress There was an effect to prevent contact noise by moving downward without contacting the uppermost winding (12).

However, the above-described spring mattress structure for the bed mattress is a structure in which the first contact preventing end 30 is disposed vertically, and thus the height of the spring is naturally increased, causing a problem that the thickness of the mattress is unnecessarily increased.

In addition, the spring structure for the bed mattress described above does not come into contact with the winding 12 of the body spring by the lowering of the first contact preventing end 30 when the load is applied. When the windings 12 of the spring are in contact with each other, there is still a limit that noise is generated.

In addition, the above-described conventional spring has a small outer diameter of the center portion and a large outer diameter of the upper portion and the lower portion as shown in FIGS. 1A to 2, so that the central portion is severely shrunk regardless of the magnitude of the load applied from the mattress. There is a drawback that you can not get a good night's sleep.

In addition, in the conventional spring, deformation occurs in the central portion of the structurally weak spring due to repeated contraction and expansion, and deformation or cracking occurs due to concentration of load due to rapid contraction of the winding when instantaneously applying a large load. Therefore, there is a disadvantage that the durability is lowered.

The present invention has been proposed in view of the above, by providing an appropriate cushioning force according to the magnitude of the external force applied to the mattress, the comfort and comfort is improved, the spring for the mattress so that contact noise is not generated during the contraction and expansion of the spring The purpose is to provide a structure.

Another object of the present invention is to provide a spring structure for a mattress which is improved in cushioning against external force applied to the mattress and prevents rapid contraction of the spring to improve durability.

In order to achieve the above object, the spring structure for the mattress according to the present invention, the spring structure for the mattress, the spring is a spring body portion formed by winding a steel wire to be located in the central portion; An upper spring part wound around the spring body part; It is provided with a lower spring portion wound to extend to the lower portion of the spring body portion, the spring is further provided with a plurality of buffer ports formed of a material having a buffer and threaded to the steel wire to prevent the generation of noise in the contraction and expansion process It features.

In addition, the buffer hole may be formed to gradually increase in diameter as the vertical gap of the wound steel wire increases.

In addition, the buffer hole may be formed in an elliptical shape in the bent portion having a small radius of curvature of the steel wire, and may be formed in a circular shape in the bent portion having a large radius of curvature.

In addition, the upper spring portion is wound to gradually decrease in diameter from the upper end of the spring body portion is formed in a structure in which the uppermost portion is wound around the flat, the lower spring portion is gradually downward from the lower end of the spring body portion After winding to reduce the diameter, the lowermost part may be formed in a flat wound structure.

According to the spring structure for the mattress according to the present invention, it is supported to have a buffer by the lower spring portion and can support a large load by the spring body portion firmly formed to prevent deformation or damage of the mattress, conical As the wound upper spring part cushions the body with light elastic force to provide comfort, the upper spring part and the lower spring part are wound in a conical shape, so that adjacent steel wires do not contact each other in the contracted state, thereby generating noise. There is no effect.

And, according to the spring structure for the mattress according to the present invention, the upper structure is soft, the middle structure provides the rigidity and coziness, the lower part performs the three functions at the same time straight up the coil, without deformation without using the mattress upside down Can be used for a long time.

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

Figure 3 is a perspective view showing a spring structure for a mattress according to an embodiment of the present invention.

Referring to Figure 3, the spring structure for the mattress according to an embodiment of the present invention so that the steel wire is wound (formed hereinafter referred to as a winding) and the spring body portion 11, and extends on top of the spring body portion 11 It is composed of a wound upper spring portion 12 and a lower spring portion 13 wound to extend under the spring body portion 11.

The spring body portion 11 is formed in the shape of a substantially cylindrical shape with the same diameter in the state of being wound by the steel wire a so as to be located at the center portion of the spring 1.

The upper spring portion 12 is wound in a conical structure in which the steel wire is gradually reduced upward from the upper end of the spring body portion 11 so as to be located at the upper portion of the spring 1, and then the uppermost portion is wound flat. It is formed in a structure.

The lower spring portion 13 is wound in a conical structure in which the steel wire is gradually reduced downward from the lower end of the spring body portion 11 so as to be located at the lower portion of the spring 1, and then the lowermost portion is wound flat. It is formed in a structure.

And, the spring body portion 11 is a large load applied from the mattress (not shown) (a sudden acting load, such as when the user moves the bed by sitting or walking momentarily, in this embodiment the load of the user is a male It is formed in the length range of 63 to 71% of the total length of the spring (total height of the spring) to support the average weight. The reason for limiting the length of the spring body part 11 is that when the drop test is repeated using a weight of 100 kg, when the spring exceeds 71%, the contraction force of the mattress is too small compared to the total thickness of the mattress. This is because it falls and is hard to provide comfort at bedtime, and when set to 63% or less, it cannot provide a solid support force against a large load applied from the mattress.

The upper spring portion 12 is formed in the upper portion of the spring to provide a direct cushion force to the sleeper, and compared with the lower spring portion 13, the upper and lower intervals of the wound wire (a) is dense and the spring 1 It is formed in the length of 18 to 22% of the total length (total). The reason for limiting the length of the upper spring portion 12 as described above is 22% as a result of repeating the rolling test (a test for measuring shaking while rolling a roller having a predetermined weight in the front and rear or left and right directions of the mattress) using a roller. If it exceeds, the bed load (rolling test using the roller of the average load of men) is severe fluctuations can not take a good night's sleep, and if less than 18%, the cushioning action can not provide comfort.

The lower spring portion 13 has a higher vertical gap between the wound wire (a) than the spring body portion 11 and a wider upper / lower interval of the steel wire (a) than the upper spring portion 12. It is formed in the length of 11 to 15% of the total length. The reason for limiting the length of the lower spring portion 13 is that when the drop test is repeatedly performed using a weight of 100 kg, if it exceeds 15%, the contraction and expansion range is too large, causing shaking in the spring body part. This is because it is not possible to provide an appropriate buffering force to the spring body portion 11 when set to less than%.

On the other hand, the spring structure for the mattress according to an embodiment of the present invention is covered with a spring cover 11, the upper spring portion 12, and the lower spring portion 13, pocket cover (not shown) formed of a fabric, etc. ) May be provided.

In addition, the upper spring portion 12 is wound in a conical shape has a structural stability, so even if a movement such as flipping during bedtime, while supporting a stable without twisting while performing a cushioning effect on the body with a light elastic force, the function of a comfortable support To perform.

And, the spring body portion 11 performs a function of a rigid support to prevent the phenomenon that the mattress is deformed or damaged while supporting the load with a firm elastic support force when the bedtime moves the bed by sitting or walking momentarily. At this time, the lower spring portion 13 contracts and expands according to the downward pressing force applied from the spring body portion 11 to perform a stable supporting action without shaking and at the same time to straighten the coil.

As described above, the spring structure for the mattress according to the embodiment of the present invention is the upper portion (upper spring portion 12) is soft, and the middle portion (spring body portion 11) provides rigidity and coziness, and the lower portion (lower bottom) Spring portion 13) can be used for a long time without deformation without performing the mattress upside down by simultaneously performing three functions to straight up the coil.

In addition, the spring structure for the mattress according to an embodiment of the present invention is adjacent to the constricted state because the upper spring portion 12 and the lower spring portion 13 having a large contraction range are wound in a conical shape when an external force is applied. The steel wires are not in contact with each other so that no metallic friction sounds are generated.
