Description

Technical Field

[0001] The utility model relates to the technical field of spring mattresses, in particular to a spring mattress with spring-in-spring structures arranged at intervals. Background Art

[0002] Spring mattress is a common type of mattress, which uses springs as a support system. These springs can be connected springs or independent springs wrapped in fabric. Independent springs are packed into bags with non-woven or cotton cloth, and then glued or ultrasonically sealed. The more coils of the spring, the higher the spring body and the softer it is. The number of springs arranged is based on the inner diameter of the spring. The smaller the inner diameter, the more springs are required, and the harder the mattress is. The springs of independent spring mattresses are not connected by wire rings, but each spring is independent. Even if the person next to the pillow turns over and moves sideways, it will not affect the sleep of the other person. At the same time, it can evenly bear the pressure of each landing point of the body, so that the body will not be sore due to being suspended in the air, which is the so-called ergonomic advantage. Compared with connected springs, independent spring mattresses feel softer when sleeping, but the support of excellent independent springs is comparable to that of connected springs. Spring mattresses are designed to provide support and comfort, while also providing appropriate elasticity and rebound. One of the advantages of spring mattresses is that they offer good ventilation, as air can flow freely between the springs, helping to keep the mattress dry and fresh. In addition, due to the elastic properties of the springs, they can also provide a certain degree of support and shock absorption, helping to reduce body pressure and make sleep more comfortable.

[0003] At present, the internal structure of most spring mattresses on the market is usually composed of multiple independent springs. These springs are of the same size, thickness, softness and hardness, so that the supporting force of each area on the mattress is the same, and it is impossible to provide appropriate support and transition for each part of the human body; when turning over or sleeping on your side, the springs inside the mattress may make some noise and produce certain vibrations, which may affect the person sleeping with you, especially when the mattress is soft, you may not feel comfortable when turning over. Summary of the invention

[0004] The utility model aims to provide a spring mattress with a spring-in-spring structure arranged at intervals in view of the defects and shortcomings of the prior art, which has a simple and reasonable structure, reduces noise and vibration, better adapts to the curves of the body, provides more flexible support, and makes turning over during sleep more natural.

[0005] In order to solve the problems existing in the background technology, the utility model adopts the following technical scheme: a spring mattress with a spring-in-spring structure arranged at intervals, the supporting component located at the bottom of the mattress is composed of transversely arranged independent spring packages and spring-in-spring spring groups arranged at intervals, the independent spring package is an independent spring wrapped in non-woven fabric, the spring-in-spring spring group is composed of an independent spring wrapped in non-woven fabric and an additional spring arranged inside the independent spring, the center of the circle of the independent spring coincides with that of the additional spring, and the diameter and elongation of the additional spring are both smaller than the diameter and elongation of the independent spring.

[0006] The "spring" in the "spring-in-spring structure" of the utility model refers to the spring. By embedding an additional spring in the independent spring, the independent spring with a larger caliber provides overall support and elasticity, and an additional spring with a smaller caliber and a shorter elongation is added inside the independent spring. These additional springs are also independent and can provide more detailed support and response according to the pressure distribution of the body; the fabric located above the spring support component is composed of foam, memory foam, latex and other materials to provide a soft and comfortable sleeping surface. Since the mattress of a normal human body will sink by 2-5cm when sleeping, when it sinks to a certain height and the additional spring is under pressure, the additional spring can provide certain support to prevent excessive sinking, so that the mattress can better adapt to the curve of the body, provide better support, comfort and durability, and reduce pressure point; when it is necessary to turn over or sleep on the side, the shoulders and waist sink more, and the additional springs with smaller caliber can respond to the body's movements more sensitively, provide more flexible support, make turning over during sleep more natural, and provide better support for side sleeping; the independent spring package and the spring-in-spring spring group are arranged at intervals to avoid excessive support or insufficient support in specific parts, and provide appropriate support and transition for each part of the human body; the utility model can set independent springs and additional springs of different specifications according to the size of the mattress, the user group (such as the elderly, children), height, weight, etc., to meet the preferences of different people for the softness and hardness of the mattress; at the same time, the additional springs in the spring-in-spring spring group of the utility model can be one or more, and the multiple springs of the "spring-in-spring structure" can disperse the pressure and extend the service life of the mattress.

[0007] Preferably, the independent spring has a diameter of 51 mm, a wire diameter of 1.5 mm, a material of 70# carbon steel, an effective number of turns of 8, and an elongation of 18 cm; the additional spring has a diameter of 51 mm, a wire diameter of 1.3 mm, a material of 70# carbon steel, an effective number of turns of 8, and an elongation of 15 cm.

[0008] The utility model adopts the above-mentioned independent spring and additional spring to form a spring-in-spring spring group and an independent spring package, and is used in human body tests with a weight of 50-90 kg, and a good sleeping experience is achieved. The utility model can also adjust the spring material according to the height and weight of the human body, and use spring combinations with different diameters, wire diameters, materials, effective turns, and elongations to meet the preferences of different people for the softness and hardness of the mattress, so that the mattress can better adapt to the body curve and provide better comfort and support.
