Description
Technical Field
[0001] This utility model belongs to the field of home mattress technology, specifically relating to a mattress that is easy to roll up and store. Background Technology
[0002] In current home settings, the demand for foldable mattresses is increasing. While traditional foam or latex mattresses offer the advantage of being lightweight, their limited material resilience means they are prone to expansion after folding due to uneven internal stress, making stable storage difficult. To facilitate mattress storage, existing technology uses straight cuts on the mattress surface to guide folding. However, this structure presents significant folding resistance, causing the folded areas to bulge after rolling and storage. Furthermore, stress concentration at the folds can lead to cracking, affecting the mattress's lifespan. Summary of the Invention
[0003] To address the shortcomings of existing technologies, this utility model provides a mattress that is easy to roll up and store. A cutting position consisting of multiple cutting grooves is set at the bending point of the core layer, and the rolled-up mattress is fixed by straps and Velcro on the straps, making the mattress folding and storage simpler and more convenient. At the same time, the cross-sectional design of the cutting grooves effectively reduces stress concentration at the bending point of the mattress, preventing the mattress from cracking and increasing the service life of the mattress.
[0004] This utility model provides the following technical solution:
[0005] A mattress that is easy to roll up and store includes a core layer and an outer cover covering the core layer. The core layer is made of soft material. Multiple cuts are provided along the length of the core layer. Each cut includes multiple cutting grooves symmetrically arranged on the upper and lower surfaces of the core layer. The cross-section of each cutting groove is a V-shape with its bottom connected to an O-shape. The V-shaped opening is located on the surface of the core layer, allowing the mattress to be bent at the cuts to achieve mattress storage.
[0006] A pair of straps are provided on both sides of the long side of the bottom surface of the cover. The straps are non-elastic webbing and have Velcro fasteners to secure the mattress when it is stored.
[0007] The mattress features multiple slots at the core layer's bends, allowing it to be folded and rolled up for easy storage. Straps and Velcro fasteners secure the rolled-up mattress, making folding and storage simple and convenient. The slots combine a V-shaped opening with a tear-resistant O-ring at the bottom, facilitating storage while effectively reducing stress concentration at the bends, preventing cracking and extending the mattress's lifespan.
[0008] Using non-elastic webbing to secure the folded mattress effectively increases the lifespan of the webbing. The length of the non-elastic webbing is set according to the actual width, length, and thickness of each mattress, which effectively prevents the mattress from deforming during storage.
[0009] As a preferred embodiment, two cutting positions are provided along the length of the core layer to achieve three-part roll-up storage of the mattress.
[0010] In a preferred embodiment, the spacing between the cutting grooves at each cutting position is equal, and the size of one or more cutting grooves located in the middle of each cutting position is larger than the size of the other cutting grooves.
[0011] When bending, the stress varies at different locations along the cut. The bending degree and stress are greatest at the center of the cut, therefore the size of the cut groove in the center is larger than that of other cut grooves. This facilitates bending of the mattress and effectively prevents tearing in the center of the cut. Furthermore, the larger size of the cut groove in the center effectively prevents localized bulging caused by insufficient bending deformation space in the central area of the cut.
[0012] In a preferred embodiment, the core layer is divided into three support regions by the cutting position, and each support region is provided with multiple ventilation grooves.
[0013] The ventilation grooves run horizontally through the core layer, increasing its breathability and accelerating the removal of heat and moisture.
[0014] In a preferred embodiment, the support area includes a first support area, a second support area, and a third support area, wherein the second support area has more ventilation grooves than the first and third support areas.
[0015] The first and third support areas correspond to the head and feet, while the second support area corresponds to the waist and hips. The number of ventilation slots affects the support strength of the core layer. In order to match the curves of the human body and ensure that different parts of the body receive appropriate support when lying down, and to prevent certain parts of the body from being suspended or too sunken into the mattress, the number of ventilation slots varies in different support areas.
[0016] In a preferred embodiment, the cross-sectional shape of the ventilation groove is rectangular, or a rectangle with its bottom connected to a circle.
[0017] The ventilation channels are located in the support area and do not participate in the bending of the mattress. For ease of manufacturing, the cross-section of the ventilation channels is designed as a rectangle. To further eliminate stress concentration at the right angle at the bottom of the rectangular ventilation channel, the cross-section of the ventilation channel can be a rectangle with the bottom connected to a circle, thereby increasing the lifespan of the mattress.
[0018] In a preferred embodiment, four cutting positions are provided along the length of the core layer, wherein the second and third cutting positions are located in the middle of the core layer, and the first and fourth cutting positions are located near the two ends of the core layer, so as to realize the four-part roll-up storage of the mattress.
[0019] In a preferred embodiment, the spacing between the cutting grooves at each cutting position is equal;
[0020] Among them, the cutting grooves of the second and third cutting positions are fewer than those of the first and fourth cutting positions;
[0021] Alternatively, one or more cutting grooves located between the first and fourth cutting positions may have a larger size than the other cutting grooves, while the cutting grooves at the second and third cutting positions may have the same size.
[0022] The first and fourth cuts are 180-degree bends, while the second and third cuts are 90-degree bends. The degree of bending at the second and third cuts is less than that at the first and fourth cuts, and the deformation of the material at the bends is positively correlated with the bending angle. Based on the actual dimensions of the mattress, the cutting grooves at different cuts are arranged differently to facilitate mattress roll-up storage while ensuring the flatness of the roll-up storage.
[0023] In a preferred embodiment, the core layer is made of materials including latex and sponge.
[0024] Latex and foam materials are easy to cut, making it convenient to create grooves and ventilation channels. Both materials are also easy to bend, making roll-up storage more convenient and effortless. Furthermore, their good elasticity means that repeated rolling and storage have minimal impact on the mattress's support performance, extending its lifespan.
[0025] In a preferred embodiment, a reinforcing strap is provided between the two straps on the bottom of the outer jacket. The two ends of the reinforcing strap are respectively connected to the straps, and the reinforcing strap is a non-elastic webbing.
[0026] When using straps to secure a rolled-up mattress, the straps on the cover may deform due to tension. Therefore, non-elastic webbing is placed horizontally on the surface between the straps as a reinforcement to prevent the cover from deforming due to excessive local stress.
[0027] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0028] The mattress features multiple slots at the core layer's bends, allowing it to be folded and rolled up for easy storage. Straps and Velcro fasteners secure the rolled-up mattress, making folding and storage simple and convenient. The slots combine a V-shaped opening with a tear-resistant O-ring at the bottom, facilitating storage while effectively reducing stress concentration at the bends, preventing cracking and extending the mattress's lifespan.
[0029] Using non-elastic webbing to secure the folded mattress effectively increases the lifespan of the webbing. The length of the non-elastic webbing is set according to the actual width, length, and thickness of each mattress, which effectively prevents the mattress from deforming during storage.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0041] The present invention will now be described in further detail with reference to the accompanying drawings:
[0042] Example 1:
[0043] This embodiment provides a mattress that is easy to roll up and store. The mattress includes a core layer 1 and an outer cover 2 that covers the core layer 1.
[0044] In this embodiment, the core layer 1 is a soft material, including sponge and latex. Latex and sponge are easy to cut, making it convenient to process cutting grooves and ventilation channels on them. At the same time, these two materials are easy to bend, making roll-up storage more convenient and labor-saving. Furthermore, these two materials have good elasticity, so repeated roll-up storage has little impact on the mattress's support performance, resulting in a longer mattress lifespan.
[0045] like Figure 1 As shown, in this embodiment, cutting positions 101 are provided at 1 / 3 and 2 / 3 of the length of the core layer 1 to achieve three-part roll-up storage of the mattress. The rolled-up mattress is as follows: Figure 4 As shown.
[0046] like Figure 9 As shown, to secure the rolled-up mattress, a pair of straps 201 are installed at 1 / 6 of the long side of the bottom surface of the cover 2. Both straps 201 have Velcro closures 202. Figure 9 The Velcro 202 on the left-hand strap 201 is located on the other surface of the visible surface of the strap 201 in the picture. Whether the mattress is in the folded or unfolded state, the Velcro 202 on the two straps 201 can be attached accordingly.
[0047] After the mattress is folded along the cut lines for storage, the straps 201 are wrapped around the side of the mattress and secured with Velcro 202. Storage and securing require no complicated skills, making it simple and convenient. When the mattress is unfolded for use, the Velcro 2012 of the two straps 2011 are fastened together, allowing the two straps 2011 to overlap on top of the surface layer 201, without affecting the normal use of the mattress.
[0048] Specifically, the Velcro 202 on the strap 201 can be set in either of the following two ways.
[0049] Method 1: Two short Velcro straps 202 are provided on each of the two straps 201, with one of the Velcro straps 202 located near the edge of the strap 201 away from the outer layer 201. When the mattress is unfolded for use, the two Velcro straps 202 on the two straps 201 can be fastened together; when the mattress is folded up, the Velcro straps 202 located on the outer side of the two straps 201 (i.e., the edge of the strap 201 away from the outer layer) can be fastened together.
[0050] Method 2 involves attaching a longer Velcro strap 202 to each of the two straps 201. When the mattress is unfolded for use, the Velcro straps 202 on the two straps 201 can be roughly aligned; when the mattress is folded up, a portion of the Velcro straps 202 on the two straps 201 can be aligned.
[0051] When using straps 201 to secure a rolled-up mattress, the area on the cover 2 where the straps 201 are located will deform due to the tension of the straps 201. Therefore, inelastic webbing 203 is horizontally installed on the surface layer between the straps 201 as a reinforcing strap to prevent the cover from deforming due to excessive local stress. The design of the reinforcing strap 203 and the straps 201 is as follows: Figure 9 As shown.
[0052] Traditional elastic straps suffer from a short lifespan due to material degradation after prolonged use. Furthermore, traditional elastic straps rely on their elasticity to stretch and secure a folded mattress. However, the straps themselves are relatively short, which can cause mattress deformation during folding, negatively impacting comfort over time. Therefore, in this embodiment, both the strap 201 and the reinforcing strap 2013 are made of non-elastic webbing to reduce the impact of folding on mattress comfort and effectively increase their lifespan.
[0053] like Figure 2As shown, the cutting position 101 includes multiple cutting grooves 103 symmetrically arranged on the upper and lower surfaces of the core layer 1, with equal spacing between each cutting groove 103. The cross-section of the cutting groove 103 is a V-shape with an O-shaped connection at the bottom, wherein the V-shaped opening is located on the surface of the core layer 1, allowing the mattress to be bent at the cutting position 101 for storage. The cross-section of the cutting groove adopts a combination of a V-shaped opening and a tear-resistant O-shaped bottom, which not only facilitates storage but also effectively reduces stress concentration at the bending point of the mattress, preventing cracking and increasing the mattress's lifespan.
[0054] During bending, the stress varies at different locations along the cut, with the greatest stress occurring at the center of the cut where the bending is most pronounced. For example... Figure 3 As shown, in this embodiment, the cutting groove 103 in the middle of the cutting position 101 adopts a large-size cutting groove 1032, while the other cutting grooves 103 adopt small-size cutting grooves 1031. This facilitates the bending of the mattress while effectively preventing tearing at the middle of the cutting position during bending, and preventing local bulging in the middle area of the cutting position due to insufficient bending deformation space. The large-size cutting groove 1032 has a wider and deeper groove than the small-size cutting groove.
[0055] like Figure 3 As shown, in this embodiment, the core layer 1 is divided into three support regions 102 by two cutting points 101, including a first support region 1021, a second support region 1022, and a third support region 1023. The first support region 1021 and the third support region 1023 correspond to the head and feet of the human body, while the second support region 1022 corresponds to the waist and hip area. To increase the breathability of the core layer and accelerate the removal of heat and moisture, multiple ventilation grooves 104 are provided in each support region 102.
[0056] The number of ventilation channels 104 not only affects the breathability of the core layer 1, but also its support strength. When a person lies flat, the lumbar region has the largest unsupported curvature and requires softer support to fill the gaps; while the buttocks are a concentrated area of mass, requiring materials with greater deformation space to distribute pressure; at the same time, the lumbar and hip areas are precisely the core areas of heat production and sweating in the human body, requiring better breathability. In order to match the curves of the human body and provide appropriate support for different parts of the body when lying down, preventing certain parts of the body from being unsupported or sinking too much into the mattress, and to increase the breathability of the second support area 1022, the second support area 1022 has more ventilation channels 104 than the first support area 1021 and the third support area 1023.
[0057] The ventilation groove 104 is located in the support area 102 and does not participate in the bending of the mattress. For ease of manufacturing, the cross-section of the ventilation groove is designed as a rectangle. To further eliminate stress concentration at the right angle at the bottom of the rectangular ventilation groove 104, the cross-section of the ventilation groove 104 can be a rectangle with the bottom connected to a circle, thereby increasing the lifespan of the mattress.
[0058] Example 2:
[0059] The difference between this embodiment and Embodiment 1 is that:
[0060] like Figure 5 and Figure 6 As shown, in this embodiment, four cutting positions 101 are provided along the length of the core layer 1, including a first cutting position 1011, a second cutting position 1012, a third cutting position 1013, and a fourth cutting position 1014. The spacing between the cutting grooves 103 of each cutting position 101 is equal. The second cutting position 1012 and the third cutting position 1013 are located in the middle of the core layer 1, while the first cutting position 1011 and the fourth cutting position 1014 are located near the two end edges of the core layer 1, respectively, to achieve four-part roll-up storage of the mattress. The rolled-up mattress is as follows: Figure 8 As shown.
[0061] The first cutting position 1011 and the fourth cutting position 1014 are bent at 180 degrees, while the second cutting position 1012 and the third cutting position 1013 are bent at 90 degrees. The degree of bending of the second cutting position 1012 and the third cutting position 1013 is less than that of the first cutting position 1011 and the fourth cutting position 1014. Since the deformation of the material at the bending point is positively correlated with the bending angle, a differentiated layout is adopted for the cutting grooves 103 of different cutting positions 101 to facilitate the rolling and storage of the mattress while ensuring the flatness of the rolling and storage.
[0062] like Figure 7 As shown, in this embodiment, the cutting groove 103 between the first cutting position 1011 and the fourth cutting position 1014 adopts a large-size cutting groove 1032, while the remaining cutting grooves 103 adopt a small-size cutting groove 1031. This facilitates the bending of the mattress while effectively preventing tearing in the middle of the cutting position during bending, and preventing local bulging in the middle area of the cutting position due to insufficient bending deformation space.
[0063] The cutting grooves 103 of the second cutting position 1012 and the third cutting position 1013 can adopt any one of the following two design methods according to the actual length of the mattress.
[0064] In method one, the cutting grooves 103 of the second cutting position 1012 and the third cutting position 1013 are fewer than those of the first cutting position 1011 and the fourth cutting position 1014;
[0065] In the second method, the cutting grooves 103 of the second cutting position 1012 and the third cutting position 1013 are the same size, and both adopt small-sized cutting grooves 1031.
[0066] In this embodiment, the material of the core layer 1, the cross-sectional shape of the cutting groove 103, and the design of the straps 201 and reinforcing straps 203 on the outer jacket 2 are all the same as in Embodiment 1, and will not be described again.
[0067] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
