Abstract
Description
Technical Field
[0001] The utility model relates to the field of bedding, in particular to a pillow. Background Art
[0002] With the fast-paced pace of modern work and life, people are increasingly stressed and spend more time looking down at work, making cervical spine problems increasingly common. The cervical pillow is a new generation of functional products designed to relieve shoulder and neck discomfort, developed based on ergonomics, bionics, physics, Traditional Chinese Medicine, and years of clinical practice. Existing cervical pillows on the market are either too hard or too soft, failing to provide the precise, ergonomic support that provides soft, supportive support in the head pit and a contoured fit around the cervical spine. Utility Model Content
[0003] The purpose of this utility model is to provide a three-layer composite pillow to solve the above technical problems.
[0004] The technical problem solved by the present invention can be achieved by adopting the following technical solutions:
[0005] The three-layer composite pillow is characterized in that it comprises an upper support layer located above and a lower support layer located below. When the upper support layer and the lower support layer are buckled together, an accommodating cavity is formed between the upper support layer and the lower support layer, and the accommodating cavity is filled with a filling layer.
[0006] The hardness of the upper support layer is less than that of the filling layer. The height of the upper surface of the filling layer gradually increases and then decreases from the front end to the rear end to form a first convex surface, and then gradually increases and then decreases to form a second convex surface.
[0007] Beneficial Effects: 1. The present invention adopts a three-layer composite structure, allowing each layer to be made of different materials, thereby achieving different softness and hardness experiences. 2. The present invention optimizes the structure of the upper surface of the filling layer, making the filling layer taller at both ends (at the cervical vertebrae) and shorter in the middle (at the head pit). On the one hand, the thickness of the upper support layer at the head pit can be increased, thereby providing soft wrapping support in the head pit area and fitting support in the cervical vertebrae. On the other hand, the position of the filling layer can be effectively limited to prevent displacement of the filling layer.
[0008] Preferably, the upper surface of the upper support layer is planar, and the lower surface of the upper support layer is provided with a first recess with an opening facing downward, wherein the height of the first recess first remains constant from the front end to the rear end, then gradually increases, then gradually decreases, then gradually increases, and then remains constant, so that the first recess is better fitted with the upper surface of the filling layer.
[0009] Preferably, the lower surface of the filling layer is provided with a second depression with an opening facing downward, and the height of the second depression gradually increases, then decreases, then increases, and then decreases from the front end to the rear end, thereby forming a wave-like structure, thereby providing a larger support area with the lower support layer, thereby preventing the filling layer and the lower support layer from moving relative to each other.
[0010] Preferably, the lower surface of the lower supporting layer is planar, and the upper surface of the lower supporting layer is provided with a protrusion matching the second recess, so as to better support the filling layer.
[0011] Preferably, the lower surface of the upper supporting layer is provided with a first inclined surface and a second inclined surface, the first inclined surface is connected to the front end of the first recess, the second inclined surface is connected to the rear end of the first recess, and the heights of the first inclined surface and the second inclined surface are lower as they are closer to the first recess. The upper surface of the lower supporting layer is provided with a third inclined surface and a fourth inclined surface, the third inclined surface is connected to the front end of the protrusion, and the fourth inclined surface is connected to the rear end of the protrusion, and the heights of the third inclined surface and the fourth inclined surface are lower as they are closer to the protrusion. Thus, the change in the height of the inclined surface is utilized to limit the relative position of the upper supporting layer and the lower supporting layer, and to avoid mutual displacement between the upper supporting layer and the lower supporting layer. More importantly, after the head socket position is compressed, the outward movement of the two ends of the upper supporting layer is limited.
[0012] Preferably, the width of the third inclined surface is greater than the width of the first inclined surface, and the width of the fourth inclined surface is greater than the height of the second inclined surface. This creates an inclined support structure at both ends of the filling layer, with the support structure resting against the third and fourth inclined surfaces. This structure not only provides better support for the filling layer but also effectively limits the relative positions of the three layers.
[0013] Preferably, the maximum heights of the first convex surface and the second convex surface are different, so as to adapt to different cervical vertebrae heights by utilizing the difference in heights.
[0014] Preferably, the lower support layer is symmetrical front to back, so that during assembly, there is no need to distinguish between the front end and the rear end, thereby improving assembly efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
[0015] Figure 1 It is a side view of the utility model;
[0016] Figure 2 This is an exploded view of the present invention. DETAILED DESCRIPTION
[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.
[0018] Reference Figure 1 and Figure 2 The three-layer composite pillow comprises an upper supporting layer 1, a lower supporting layer 2 and a filling layer. The hardness of the upper supporting layer 1 is less than that of the filling layer.
[0019] About upper support layer 1
[0020] The upper support layer 1 is located above. The upper surface of the upper support layer 1 is planar, and the lower surface of the upper support layer 1 is provided with a first depression with a downward opening. The height of the first depression remains constant from the front end to the rear end, then gradually increases, then gradually decreases, then gradually increases, and then remains constant. This allows the first depression to better fit the upper surface of the filling layer. The lower surface of the upper support layer 1 is provided with a first inclined surface and a second inclined surface. The first inclined surface is connected to the front end of the first depression, and the second inclined surface is connected to the rear end of the first depression. The heights of the first and second inclined surfaces decrease as they are closer to the first depression.
[0021] About fill layers
[0022] After the upper and lower support layers 1 and 2 are fastened together, a receiving cavity is formed between them. The receiving cavity is filled with a filling layer. The height of the upper surface of the filling layer gradually increases and then gradually decreases from the front end to the rear end, forming a first convex surface 3. It then gradually increases and then gradually decreases to form a second convex surface 4.
[0023] The lower surface of the filling layer is provided with a second depression with an opening facing downward. The height of the second depression gradually increases from the front end to the rear end, then gradually decreases, then gradually increases, and then gradually decreases. This forms a wave-like structure, providing a larger support area for the lower support layer 2, thereby preventing the filling layer and the lower support layer 2 from moving relative to each other.
[0024] About the lower support layer 2
[0025] The lower surface of the lower support layer 2 is planar, and the upper surface of the lower support layer 2 is provided with a protrusion that matches the second recess. This allows for better support of the filling layer. The upper surface of the lower support layer 2 is provided with a third inclined plane and a fourth inclined plane. The third inclined plane is connected to the front end of the protrusion, and the fourth inclined plane is connected to the rear end of the protrusion. The closer the third inclined plane and the fourth inclined plane are to the protrusion, the lower the height. The change in the height of the inclined plane is used to limit the relative position of the upper support layer 1 and the lower support layer 2, thereby avoiding mutual displacement between the upper support layer 1 and the lower support layer 2. More importantly, after the head socket position is compressed, the outward movement of the two ends of the upper support layer 1 is limited.
[0026] The width of the third slope is greater than that of the first slope, and the width of the fourth slope is greater than the height of the second slope. This creates a sloped support structure at both ends of the filling layer, resting against the third and fourth slopes. This structure not only provides better support for the filling layer but also effectively limits the relative position of the three layers.
[0027] Preferably, the maximum heights of the first convex surface 3 and the second convex surface 4 are different. Figure 1 The maximum height of the first convex surface 3 is greater than the maximum height of the second convex surface 4. This difference in height allows for adaptation to varying cervical vertebrae heights. Preferably, the lower support layer 2 is symmetrical front to back. This eliminates the need to distinguish between the front and back ends during assembly, improving assembly efficiency. Preferably, the upper support layer 1 utilizes 40D40N memory foam, the lower support layer 2 utilizes 40D50N memory foam, and the filling layer utilizes highly resilient support foam.
