A waist support pillow

Abstract

A lumbar support pillow has a core composed of several interconnected core units. Each core unit consists of a horizontal ring and four vertical rings, with the four vertical rings spaced apart along the circumference of the horizontal ring. The core units are interconnected horizontally and longitudinally via the vertical rings, forming a three-dimensional structure. The advantages of this invention are: 1. The core unit utilizes multiple horizontal rings connected by vertical rings for support and stability, resulting in a strong supporting force. Furthermore, its simple structure, consisting only of horizontal and vertical rings, is advantageous. 2. When subjected to pressure from the human body, the horizontal and vertical rings can press against each other, bringing them closer together or allowing them to rotate. This reduces gaps between the rings and increases overall strength. The core also changes shape according to the pressure on the lower back, better adapting to the curvature and shape of the lumbar spine, exhibiting an adaptive adjustment mechanism.

Description

Technical Field

[0001] This utility model relates to a lumbar support pillow. Background Technology

[0002] Existing lumbar support pillows generally fall into two categories: inflatable lumbar support pillows and filled lumbar support pillows.

[0003] 1. Inflatable pillows generally consist of a pillowcase and an inflation device. Therefore, their structure is complex, manual inflation is cumbersome, and it's difficult to ensure consistent inflation, leading to unstable support. Furthermore, air leakage is a problem; the pillowcase is prone to leakage over time, resulting in poor stability.

[0004] 2. Lumbar support pillows with fillings include pillowcases and pillow cores. The pillow cores are made of solid materials, such as memory foam and polyurethane. Because the internal structure of the pillow core is not taken into account, the support is insufficient and it is easy to deform. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to overcome the above-mentioned defects of the prior art and provide a lumbar support pillow with stable structure and strong support.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A lumbar support pillow includes a pillowcase and a pillow core, characterized in that: the pillow core is composed of several pillow core units connected to each other; each pillow core unit consists of a horizontal ring and four vertical rings, the four vertical rings are spaced apart along the circumference of the horizontal ring, and the several pillow core units are interconnected in the horizontal and front-back directions through the interconnection of the horizontal rings, and in the vertical direction through the interconnection of the vertical rings, forming a three-dimensional structure to constitute the pillow core.

[0007] Better still, the four vertical rings are a left vertical ring, a right vertical ring, a rear vertical ring, and a front vertical ring, which are evenly arranged along the circumference. Between pillow core units in the same layer, two adjacent horizontal rings are connected to each other by the left or right vertical rings that are fitted on them, either to the left or right. They are also connected to each other by the rear or front vertical rings, either to the front or back. Multiple pillow core units are interconnected to form a unit set. Between two unit sets, the left or right vertical ring of the horizontal ring of the upper pillow core unit is fitted to the rear or front vertical ring of the lower horizontal ring. By repeating the above connection method, two unit sets form a planar unit. Multiple planar units are superimposed in the thickness direction. Through the nested connection of the corresponding vertical rings of the upper and lower unit sets, the pillow core is finally formed. This structure is more compact.

[0008] Even better, the horizontal ring and the four vertical rings are connected at an angle of 90 degrees.

[0009] Even better, the outermost vertical rings connected to the outermost horizontal rings can be omitted, as these vertical rings are not interconnected with other rings, making them difficult to fix and saving materials.

[0010] Ideally, the horizontal ring is exactly the same as the vertical ring, which facilitates manufacturing.

[0011] Compared with the prior art, the advantages of this utility model are: 1. Because the pillow core unit uses multiple horizontal rings connected by vertical rings to form a connection and support, its structure is stable and has strong support; moreover, it consists of only horizontal and vertical rings, making its structure simple.

[0012] 2. When the pillow core is subjected to pressure from the human body, the horizontal and vertical rings can press against each other and rotate, thereby reducing the gaps between the rings and increasing the overall strength, thus providing greater support for the human waist. At the same time, the pillow core also changes shape with the pressure of the human waist, thus better adapting to the curvature of the lumbar spine and the shape of the waist, and has an adaptive adjustment function.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] In this embodiment, the directional terms such as horizontal, vertical, up, down, front, back, left, and right are specific directions used for the convenience of description in relation to the drawing orientation in this embodiment, and are not intended to limit its scope of protection. This is true for those skilled in the art.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, a lumbar support pillow includes a pillow core and a pillowcase (not shown in the figure).

[0022] The pillow core includes a pillow core unit, which comprises a horizontal circular ring 1 and four vertical circular rings 2, 3, 4, and 5 spaced apart and nested around the circumference of the horizontal circular ring 1. The four vertical circular rings are evenly arranged along the circumference. Figure 1 .

[0023] The angles between the left vertical ring 2, the rear vertical ring 3, the right vertical ring 4, and the front vertical ring 5 and the horizontal ring 1 are A, which is 90 degrees in this embodiment.

[0024] It should be noted that when the vertical ring is used as a connector for the horizontal ring 1, its number changes depending on the horizontal ring 1 being connected: the left horizontal ring 1 is labeled as right vertical ring 4, and the right horizontal ring 1 is labeled as left vertical ring 2, although they are actually the same vertical ring. Conversely, the right horizontal ring 1 is labeled as right vertical ring 4, and the left horizontal ring 1 is labeled as left vertical ring 2. Figure 2 , Figure 3 The markings 4(2) and 2(4) in the text have this meaning. Similarly, the front horizontal ring 1 is marked as the rear vertical ring 3, and the rear horizontal ring 1 is marked as the front vertical ring 5, which are actually the same vertical ring. Conversely, the rear horizontal ring 1 is marked as the rear vertical ring 3, and the front horizontal ring 1 is marked as the front vertical ring 5. Figure 2 , Figure 3 , Figure 4 The markings 5 ​​(3) and 3 (5) in the text have this meaning.

[0025] Multiple pillow core units are connected together in the horizontal direction by left vertical ring 2 or right vertical ring 4, and in the front-back direction by adjacent rear vertical ring 3 or front vertical ring 5. In the vertical direction, they are connected together by left vertical ring 2 or right vertical ring 4 and rear vertical ring 3 or front vertical ring 5.

[0026] In this embodiment, adjacent horizontal rings 1 of the same layer of pillow core units can be connected to each other by looping the left vertical ring 2 or the right vertical ring 4 around them to the left or right, and can be connected to each other by looping the rear vertical ring 3 or the front vertical ring 5 forward or backward. Multiple pillow core units are interconnected to form a unit set, see Figure 2 , Figure 3 .

[0027] Between the two-layer unit sets, the left vertical ring 2 or right vertical ring 4 of the horizontal ring 1 of the upper pillow core unit is nested with the rear vertical ring 3 or front vertical ring 5 of the lower horizontal ring 1. By repeating the above connection method, the two-layer unit sets constitute a planar unit, as shown in the figure. Figure 2 , 3 .

[0028] Multiple planar units are stacked in the thickness direction. In this embodiment, four planar units are used. The left vertical ring 2 (4) of the upper unit set and the corresponding left vertical ring 2 (4) of the lower unit set are nested and connected by a rear vertical ring 3 (5) perpendicular to them, thus forming the pillow core. See Figure 4 .

[0029] like Figure 5 , 6 As shown, the pillow core can be trimmed or directly connected to form a shape that meets the needs of the lumbar support pillow. Figure 4 The curve shape shown can fit the waist, and other shapes can also be formed to fit the waist.

[0030] Figure 2 The outermost left vertical ring 2 and rear vertical ring 3, which are connected to the outermost horizontal ring, are not connected to other horizontal or vertical rings. Therefore, these left vertical rings 2 and rear vertical rings 3 are prone to wobbling and the connection is unstable. Therefore, they can be omitted.

[0031] In this embodiment, the diameters of the horizontal ring 1, the vertical ring 2, the rear vertical ring 3, the right vertical ring 4, and the front vertical ring 5 are all the same; obviously, they can also be different.

[0032] The pillowcase can be made of elastic fabric, which is matched with the pillow core and can adapt to changes in external pressure.

[0033] The pillow core can be made of an elastic material such as polyurethane, making the horizontal and vertical rings of the pillow core more flexible.
