Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of mattresses and relates to a bed core with elastic fabric and a mattress. Background Art
[0002] Existing electric mattress cores typically use conventional bagged mattress cores without edge-limiting materials like steel edging and support springs. Instead, they are covered with non-woven fabric. However, this approach results in poor bendability. Without the non-woven fabric covering, the gaps between the springs are used to create bending space, resulting in significant spring elasticity and difficulty in dimensional control. Summary of the Invention
[0003] In view of the problems existing in the prior art, the utility model provides a bed core and a mattress with elastic fabric, aiming to overcome the defect of poor bendability of the prior bed core.
[0004] The utility model is achieved in this way:
[0005] A bed core with elastic fabric comprises a spring layer formed by arranging a plurality of single springs, the upper surface of the spring layer being provided with elastic fabric, the elastic fabric being adhered to the spring layer by a glue-dotting structure, the single spring comprising a spring body and an independent bag sleeved on the spring body, the glue-dotting structure being located on the independent bag, and a deformation gap being provided at the upper ends between adjacent single springs in the length direction of the spring layer.
[0006] Elastic cloth is fixed on the upper surface of the spring layer, which can form constraints between individual springs, facilitate the size control of the bed core, and at the same time make the bed core have better bending properties, so that the bed core without edge-restricting materials can also better adapt to the bending requirements of the electric bed.
[0007] Preferably, the lower surface of the spring layer is provided with elastic fabric, which can better constrain the single spring and improve the controllability of the bed core size.
[0008] Preferably, the elastic force of the stretch fabric in the length direction is greater than its elastic force in the width direction. Since the bed core does not need to bend in the width direction, the elastic force of the stretch fabric in the width direction is smaller, so that the stretch fabric can better constrain the width dimension of the bed core, which is conducive to improving the structural stability of the bed core.
[0009] Preferably, the width of the deformation gap is 0.4-6 cm.
[0010] Preferably, the glue dispensing structure includes a plurality of glue dispensing positions, and the glue dispensing positions are linear. The linear glue dispensing positions can make the elastic fabric and the independent bag more securely fixed.
[0011] Preferably, the glue point extends along the length of the elastic fabric. This glue point structure can be used with a double-Y structure mattress core. Since the extension direction of the glue point greatly limits the deformation ability of the elastic fabric in the length direction when the double-Y structure mattress core deforms in the length direction, it will not have a significant impact on the force applied to the glue point, but can better constrain the length dimension of the mattress core.
[0012] Preferably, the glue point extends along the width direction of the elastic fabric. This glue point structure can be used with ordinary bagged mattress cores. The extension direction of the glue point can prevent the glue point from being subjected to excessive force when the mattress core is bent, thereby preventing the elastic fabric and the independent bag from separating at the glue point.
[0013] Preferably, the glue spot corresponds to the single spring one-to-one, and is located in the middle area of the end of the single spring. This allows the elastic fabric to better constrain the position of the single spring and better control the size of the bed core.
[0014] Preferably, the length of the dispensing position is greater than 10% of the diameter of the single spring and smaller than the diameter of the single spring.
[0015] A mattress comprises the above-mentioned bed core and an outer cover, wherein the outer cover is wrapped around the bed core.
[0016] The utility model has the following beneficial effects: elastic cloth is fixed on the upper surface of the spring layer, which can form constraints between the individual springs, facilitate the size control of the bed core, and at the same time make the bed core have better bending properties, so that the bed core without edge-limiting materials can also better adapt to the bending requirements of the electric bed.

[0029] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings to make the technical solution of the present invention easier to understand and grasp. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0030] This embodiment provides a mattress, such as Figure 1 As shown, it includes a bed core 10 and a cover 20, wherein the cover 20 is wrapped around the bed core. Figure 2 As shown, the bed core includes a spring layer 100 formed by arranging multiple single springs 110. The upper surface of the spring layer 100 is provided with a stretch fabric 200, and the stretch fabric 200 is adhered to the spring layer 100 by a glue point structure. The single spring 110 includes a spring body 111 and an independent bag 112 mounted on the spring body 111. The glue point structure is located on the independent bag 112. The upper ends of the adjacent single springs 110 in the length direction of the spring layer 100 have a deformation gap 120. This embodiment is based on the consideration of production efficiency, as shown in FIG. Figure 3-6 As shown, the plurality of single springs 110 are in the form of a spring string. Figure 2 , the direction in which the human body lies, and the bending direction of the electric mattress are the length direction of the spring layer 100.
[0031] The upper surface of the spring layer 100 is fixed with elastic cloth 200, which can form constraints between the individual springs 110, facilitate the size control of the bed core, and at the same time make the bed core have better bending properties, so that the bed core without edge-limiting materials can also better adapt to the bending requirements of the electric bed.
[0032] In this embodiment, the elastic fabric 200 is only provided on the upper surface of the spring layer 100 .
[0033] Furthermore, the elastic force of the stretch fabric 200 in the length direction is greater than its elastic force in the width direction. The stretch fabric 200 has no or low rebound effect in the width direction. Since the bed core does not require bending in the width direction, the elastic force of the stretch fabric 200 in the width direction is relatively small. This allows the stretch fabric 200 to better constrain the width dimension of the bed core, thereby improving the structural stability of the bed core.
[0034] like Figure 3 、 5 As shown, the deformation gap 120 is the distance between the diameters of the single springs 110, and the width of the deformation gap 120 is 0.4-6 cm, that is, the dimension C in the figure is 0.4-6 cm, for example, 0.5, 1, and 3.2 cm are used.
[0035] like Figure 3-6 As shown, the glue dispensing structure includes a plurality of glue dispensing positions 300, each of which is linear. The linear glue dispensing positions 300 can more reliably secure the elastic fabric 200 to the independent bag 112. In other optional embodiments, the glue dispensing positions 300 can also be in the form of dots.
[0036] like Figure 1 、 3 As shown in Figures 4 and 5, the glue dispensing position 300 extends along the length direction of the elastic fabric 200. This glue dispensing structure can be used with a double-Y structure bed core. The double-Y structure bed core is provided with an opening structure in the corresponding bending area of the electric bed. The opening structure allows the single spring 110 in the area to adapt to the bending of the electric bed, so that the mattress in the area fits the bed frame. For the specific structure of the double-Y structure bed core, please refer to the Chinese patent document with application number 2023234899176. Since the extension direction of the glue dispensing position 300 greatly limits the deformation ability of the elastic fabric 200 in the length direction when the double-Y structure bed core is deformed in the length direction, it will not have much impact on the force applied to the glue dispensing position 300. Instead, it can better constrain the length direction size of the bed core.
[0037] The deformation gap 120 is located between adjacent single springs 110 in the same spring string, and the independent pockets 112 between the single springs 110 have a cutout 113. The middle of the single spring has a raised adhesive portion 114, and adjacent spring strings are adhered by the adhesive portion.
[0038] like Figure 2 、 3 As shown, the glue spot 300 corresponds to the single spring 110 one by one, and the glue spot 300 is located in the middle area of the end of the single spring 110. This allows the elastic fabric 200 to better constrain the position of the single spring 110 and better control the size of the bed core.
[0039] like Figure 3 As shown, the length of the dispensing position 300 is greater than 10% of the diameter of the single spring 110 and smaller than the diameter of the single spring 110. That is, the dimension A relative to the dimension B in the figure must satisfy 10%≤A / B≤100%.
[0040] Example 2
[0041] like Figure 7-10 As shown, the glue dispensing position 300 can also extend along the width direction of the elastic fabric 200. This glue dispensing structure can be used with ordinary bagged mattress cores. The extension direction of the glue dispensing position 300 can prevent the glue dispensing position 300 from being subjected to excessive force when the mattress core is bent, thereby preventing the elastic fabric 200 and the independent bag from separating at the glue dispensing position 300.
[0042] The deformation gap 120 is located between adjacent single springs 110 of different spring strings, which can reduce the constraint of the independent bag on the deformation of the bed core and facilitate the bending of the bed core.
[0043] The other structures of this embodiment are consistent with those of the first embodiment.
[0044] Example 3
[0045] The mattress core in the first embodiment is a single layer of elastic fabric. This embodiment uses a double layer of elastic fabric. Specifically, Figure 11 As shown, a stretch fabric 200 is further provided on the lower surface of the spring layer 100. This can better constrain the single spring 110 and improve the controllability of the bed core size.
[0046] The other structures of this embodiment are consistent with those of the first embodiment.
