Description

Technical Field

[0001] This utility model belongs to the field of mattress technology, specifically relating to an independent spring mattress. Background Technology

[0002] Pocket spring mattresses feature springs that operate independently to provide support and conform to the body's curves, allowing muscles to relax fully, relieving pressure, creating a superior sleep environment, and improving sleep quality. However, because pocket springs often use non-woven fabric to encase the spring units, their shock absorption and energy dissipation effects are limited. This results in the spring's reaction force not being effectively dissipated, causing noticeable vibration transmission when compressed. This vibration affects comfort and also generates noise, disrupting deep sleep. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an independent spring mattress.

[0004] To achieve the above objectives, this utility model discloses an independent spring mattress, including a bottom connecting pad, a top connecting pad, and a cushioning support pad. The cushioning support pad includes multiple independent spring assemblies, and the bottom and top of each spring assembly are respectively connected to the bottom connecting pad and the top connecting pad.

[0005] The spring assembly includes an elastic sleeve, an elastic connecting post, a spring, and an upper elastic connecting piece; the bottom surface of the elastic sleeve is connected to the bottom connecting pad, and an installation chamber is provided inside the elastic sleeve; the elastic connecting post stands upright in the installation chamber, and the bottom surface of the elastic connecting post is connected to the bottom surface of the installation chamber; the spring is disposed in the installation chamber and sleeved on the outside of the elastic connecting post; the upper elastic connecting piece covers the installation chamber, and the bottom surface of the upper elastic connecting piece is connected to the top surface of the elastic connecting post, and the top surface of the upper elastic connecting piece is connected to the top connecting pad.

[0006] Preferably, the elastic sleeve includes a lower elastic connecting piece and an elastic connecting sleeve, the bottom surface of the lower elastic connecting piece is connected to the bottom connecting pad, the elastic connecting sleeve is connected to the lower elastic connecting piece, and the upper elastic connecting piece covers the top surface of the elastic connecting sleeve.

[0007] Preferably, the elastic connecting sleeve is formed by connecting the two ends of the elastic sheet that are in opposite positions.

[0008] Preferably, the outer wall of the elastic connecting sleeve is provided with multiple corrugated grooves, which are spaced apart from top to bottom.

[0009] Preferably, the upper elastic connecting piece has a clearance hole at the middle position, and the top end of the elastic connecting post is inserted into the clearance hole.

[0010] Preferably, the elastic connecting column has a cavity that extends through both ends of it.

[0011] Preferably, the upper elastic connecting piece is bonded and fixed to the elastic sleeve.

[0012] Preferably, the elastic sleeve is a sponge sleeve, and / or the elastic connecting post is a sponge post, and / or the upper elastic connecting piece is a sponge piece.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] When the user applies pressure to the spring, the side walls of the elastic sleeve and the elastic connecting post are compressed and deformed, thereby absorbing energy. When the spring is no longer compressed and returns to its original position, because the spring's return response is faster than that of the elastic sleeve and the elastic connecting post, the two elastic elements can prevent the elastic elements from rebounding quickly, which also has an energy-absorbing effect. This improves the energy absorption effect of the entire spring assembly, making the mattress more stable during use, which is conducive to improving sleep quality, and at the same time significantly alleviating the noise problem caused by high elasticity and vibration.

[0015] The elastic sleeve and upper elastic connecting plate wrap the column spring, which has better sound insulation performance compared to the existing technology of wrapping the spring with non-woven fabric. This can further reduce spring noise and improve sleep quality. At the same time, it can also reduce the pressure of the spring on the skin and capillaries, and improve sleep comfort.

[0016] The spring is encased within an elastic sleeve and an upper elastic connecting piece, which protects the spring and extends its service life. The spring is fitted over the elastic connecting post and is restrained by it, thus ensuring stable compression or expansion along the axial direction, resulting in more stable operation.

Detailed Implementation

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] An independent spring 430 mattress, see Figures 1-2 It includes a bottom connecting pad 100, a top connecting pad 200 and a cushioning support pad 300. The cushioning support pad 300 includes multiple independent spring assemblies 400. The bottom and top of each spring assembly 400 are connected to the bottom connecting pad 100 and the top connecting pad 200 respectively, so that the multiple spring assemblies 400 form a whole.

[0027] See Figure 3 The spring assembly 400 includes an elastic sleeve 410, an elastic connecting post 420, a spring 430, and an upper elastic connecting piece 440. The bottom surface of the elastic sleeve 410 is connected to the bottom connecting pad 100, and an installation chamber 411 is provided inside the elastic sleeve 410. The elastic connecting post 420 stands upright in the installation chamber 411, and the bottom surface of the elastic connecting post 420 is connected to the bottom surface of the installation chamber 411. The spring 430 is disposed in the installation chamber 411 and sleeved on the elastic connecting post 420. The upper elastic connecting piece 440 covers the installation chamber 411, and the bottom surface of the upper elastic connecting piece 440 is connected to the top surface of the elastic connecting post 420. The top surface of the upper elastic connecting piece 440 is connected to the top connecting pad 200.

[0028] When the user applies pressure to the spring 430, the sidewalls of the elastic sleeve 410 and the elastic connecting post 420 are compressed and deformed, thus achieving energy absorption. When the spring 430 is no longer compressed and returns to its original position, because the return response of the spring 430 is faster than that of the elastic sleeve 410 and the elastic connecting post 420, the two elastic elements can prevent the elastic elements from rebounding too quickly, also achieving energy absorption. This improves the energy absorption effect of the entire spring assembly 400, making the mattress more stable during use, which is beneficial to improving sleep quality, and significantly alleviating the noise problem caused by high elasticity and vibration. The elastic sleeve 410 and the upper elastic connecting piece 440 wrap the column spring 430, which has better sound insulation performance than the existing technology that uses non-woven fabric to wrap the spring 430. This can further reduce the noise of the spring 430, further improve sleep quality, and at the same time, reduce the pressure of the spring 430 on the skin and capillaries, improving sleep comfort. The spring 430 is enclosed within the elastic sleeve 410 and the upper elastic connecting piece 440, which protects the spring 430 and extends its service life. The spring 430 is fitted outside the elastic connecting post 420 and is limited by the elastic connecting post 420, thus enabling it to compress or open stably in the axial direction, resulting in more stable use.

[0029] The number of spring assemblies 400 is determined according to the size of the mattress. Their specific distribution is as follows: the spring assemblies 400 are arranged close together along the front-to-back and left-to-right directions. In this way, in addition to forming a stable overall structure through the bottom connecting pad 100 and the top connecting pad 200, the four adjacent spring assemblies 400 also limit each other, making the overall structure even more stable.

[0030] In this embodiment, the elastic sleeve 410 is a sponge sleeve, the elastic connecting post 420 is a sponge post, and the upper elastic connecting piece 440 is a sponge piece. In other optional embodiments, the elastic sleeve 410, the elastic connecting post 420, and the upper elastic connecting piece 440 are made of PU material.

[0031] See Figure 3 The elastic sleeve 410 includes a lower elastic connecting piece 412 and an elastic connecting sleeve 413. The bottom surface of the lower elastic connecting piece 412 is connected to the bottom connecting pad 100, and the elastic connecting sleeve 413 is connected to the lower elastic connecting piece 412. The upper elastic connecting piece 440 covers the top surface of the elastic connecting sleeve 413. The elastic sleeve 410 is configured as a separate lower elastic connecting piece 412 and elastic connecting sleeve 413, which facilitates manufacturing.

[0032] Among them, the lower elastic connecting piece 412 is also a sponge piece, and the elastic connecting sleeve 413 is an elastic piece (such as a sponge piece, see [link]). Figure 4The two opposite ends are joined together. Thus, the lower elastic connecting piece 412, the elastic connecting sleeve 413, and the upper elastic connecting piece 440 are all sheet-like structures, which can be directly cut during processing, making processing convenient; as for the elastic connecting sleeve 413, it can be joined together after cutting, making production convenient.

[0033] In this embodiment, the outer wall of the elastic connecting sleeve 413 is provided with multiple corrugated grooves 414, which are spaced apart from top to bottom. In this way, when the spring assembly 400 is compressed, the elastic connecting sleeve 413 can be compressed in the vertical direction under the guidance of the corrugated grooves 414, reducing the occurrence of skewing and improving the stability and user experience.

[0034] In this embodiment, a clearance hole 441 is provided at the middle position of the upper elastic connecting piece 440 and the lower elastic connecting piece 412, and the top end of the elastic connecting post 420 is inserted into the clearance hole 441, so that the elastic connecting post 420 can be stably connected inside the elastic sleeve 410.

[0035] In this embodiment, the elastic connecting post 420 is provided with a cavity 421 that passes through both ends of it. In this way, when the spring assembly 400 is compressed, the elastic connecting post 420 can deform along the inside, reducing the problem that the middle position of the post will bulge outward and interfere with the spring 430 when it is compressed, or even be cut by the spring 430, because it is a solid post. This improves the service life of the elastic connecting post 420.

[0036] In this embodiment, the elastic connecting sleeve 413 is bonded and fixed to the upper elastic connecting piece 440 and the lower elastic connecting piece 412, the upper elastic connecting piece 440 is bonded to the top connecting pad 200, and the lower elastic connecting piece 412 is bonded to the bottom connecting pad 100.

[0037] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
