Description

Technical Field

[0001] This application relates to the field of compressed roll mattress technology, specifically a compressed roll mattress. Background Technology

[0002] Mattresses are a common household item. Existing mattresses are generally made of springs, with a frame connecting the top and bottom edges to distribute the pressure evenly. Although mattresses are not heavy, they are bulky and take up a lot of space during transportation, increasing transportation costs. To solve the above problems, the current method is to compress the mattress, roll it up, and then pack it in a box for transportation.

[0003] Compression roll mattresses are compressed to 1 / 3 of their original volume using professional equipment (thickness compressed from 20cm-26cm to 2cm-5cm), rolled into a cylindrical shape, and then sealed in plastic film. After unpacking, the mattress will automatically spring back to its original size within minutes, making installation convenient.

[0004] For example, the patent with publication number CN221129402 U discloses a vacuum compression mattress that is easy to roll up. This patent connects the longitudinally and transversely arranged fabric covers with positioning cloth, which makes it easy to limit the compression axis of the springs and avoid the springs tilting and deforming, which would cause inconvenience in subsequent rolling up and damage to the overall restoring ability of the mattress. Secondly, by setting a first storage tube, a second storage tube and a third storage tube between the first frame and the second frame, the first frame and the second frame can slide and limit through the first storage tube, the second storage tube and the third storage tube. This not only avoids the force dispersion of many springs and effectively avoids damage or collapse of the edge springs, but also further improves the axial stability and compression performance of the first frame and the second frame and even the edge springs, making it easier to compress and roll up the mattress later. Moreover, through multi-layer limiting compression, it can also adapt to the final axial compression height of the springs.

[0005] Although the aforementioned patent achieves the rolling up of the mattress along its length, it does not compress the mattress along its width. As a result, the rolled-up mattress still has a relatively long size. When entering small apartments or narrow environments such as elevators / hallways, the long size still makes the mattress difficult to move around. Therefore, it is necessary to provide a mattress that can be compressed and rolled up to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0044] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0045] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0046] like Figures 1-2 As shown, this application provides a compressed roll mattress, including a bottom frame 1, which serves as the support of the mattress and mainly functions to protect the internal structure of the mattress and enhance breathability and wear resistance. The bottom frame 1 is generally made of non-woven fabric or breathable mesh fabric. The bottom of the bottom frame 1 is provided with a first ventilation hole 11, which is mainly used to enhance the overall breathability of the mattress.

[0047] A guardrail 2 is provided at the upper end of the bottom frame 1. A first zipper (not shown in the figure) is provided around the connection between the guardrail 2 and the bottom frame 1. The first zipper facilitates the connection and disassembly of the guardrail 2 and the bottom frame 1. At the same time, the guardrail 2 is mainly made of hard sponge, which can enhance the support of the mattress edge, prevent the mattress edge from collapsing, and extend the life of the mattress.

[0048] A top frame 3 is provided at the upper end of the enclosure 2. The top frame 3 is a fabric layer that can directly contact the human body and determines the appearance, feel and initial breathability of the mattress. The top frame 3 is generally made of materials such as cotton, linen, and knitted fabric, focusing on skin-friendliness and breathability. A second zipper (not shown in the figure) is provided around the connection between the top frame 3 and the enclosure 2. The second zipper facilitates the connection and disassembly of the top frame 3 and the enclosure 2 for subsequent cleaning.

[0049] Continue to refer to Figures 1-2 A top plate 4 is provided between the support mechanism 5 and the top frame 3. The top plate 4 is the filling layer of the mattress. The top plate 4 adjusts the firmness, fit and wrapping feel of the mattress by combining different materials. In this application, the top plate 4 is made of latex material, so that the top plate 4 can be breathable and mite-proof, and can provide elastic support. A second ventilation hole 41 is provided on the top plate 4. The second ventilation hole 41 mainly cooperates with the first ventilation hole 11 to increase the overall air circulation of the mattress.

[0050] Thus, the bottom frame 1, the enclosure 2, and the top plate 4 constitute the overall external structure of the mattress, hereinafter referred to as the outer shell. An accommodating space is formed inside the three components. A support mechanism 5 is installed inside this accommodating space. The support mechanism 5 is used to bear the weight of the human body, distribute pressure, and maintain the natural curvature of the spine. In this application, the support mechanism 5 mainly adopts independent pocket springs, which makes the support mechanism 5 quiet and interference-free. Each spring operates independently, which is suitable for people who are easily awakened. The structure of the support mechanism 5 and the independent pocket springs will be described in detail later.

[0051] To facilitate the compression and rolling of the mattress, such as Figures 3-4 As shown, the support mechanism 5 includes a base 51 located at the bottom of the bottom frame 1. The base 51 can be made of latex material to facilitate compression and rolling. Multiple sets of elastic components (not shown in the figure) are provided on the base 51. The multiple sets of elastic components are evenly arranged along the length of the mattress. At the same time, every two adjacent sets of elastic components have the same size folding gap (not shown in the figure). The folding gap is used as the folding position when the mattress is rolled up.

[0052] Understandably, when the mattress is wrapped in a vacuum film and compressed by vacuuming, multiple sets of elastic components can be folded along the folding gaps to facilitate the integration of the elastic components into a roll. Since a special folding gap is provided in this application, the mattress is easier to roll up, and the size can be fixed, which facilitates subsequent packaging.

[0053] In this application, the elastic components can be sized as needed, and the gap between the two sets of elastic components can also be customized to meet the needs of different users.

[0054] like Figure 3 , Figure 6 and Figure 8 As shown, the elastic component includes a first slide 52 fixedly mounted on a base 51. Two sets of first guide rails 521 are arranged on the first slide 52 along the width direction of the mattress. Multiple sets of first spring seats 54 are slidably arranged on both sides of the first guide rails 521. Each first spring seat 54 is provided with a first mating groove 541 that cooperates with the first guide rails 521. Thus, through the cooperation between the first guide rails 521 and the first mating grooves 541, the multiple sets of first spring seats 54 can slide along the first guide rails 521.

[0055] like Figure 4 , Figure 7 and Figure 10 As shown, a second slide 57 corresponding to the first slide 52 is provided on the top plate 4. Two sets of second guide rails 571 are provided on the second slide 57 along the width direction of the mattress. Multiple sets of second spring seats 55 are slidably arranged on both sides of the second guide rails 571. The second spring seats 55 are corresponding to the first spring seats 54. At the same time, a second mating groove 551 that cooperates with the second guide rails 571 is provided on the second spring seats 55. Thus, through the cooperation of the second guide rails 571 and the second mating grooves 551, multiple sets of second spring seats 55 can slide along the second guide rails 571. At least four sets of springs 53 are fixedly installed between the corresponding second spring seats 55 and the first spring seats 54.

[0056] It is understood that the first spring seat 54, the second spring seat 55 and the spring 53 between them constitute a whole. For ease of explanation, the whole is defined as a spring pack. The spring pack can be regarded as an independent pocket spring. Thus, under the action of the first spring seat 54 and the second spring seat 55, the spring pack can move along the width of the mattress.

[0057] It should be noted that both the first slide 52 and the second slide 57 are made of spring steel, thus both have a certain rigidity to maintain the stability of the spring assembly. At the same time, both have the same length and are less than the width of the base 51. Therefore, when storing the mattress, you can choose to store it according to the width of the base 51 or according to the length of the first slide 52 (second slide 57). In this case, the length of the rolled-up mattress will be slightly reduced, which can be adapted to smaller apartments or narrow elevator / hallway environments.

[0058] In practical use, multiple sets of spring packs are arranged symmetrically on both sides. In this embodiment, the multiple sets of spring packs are arranged in an odd number of groups, so that the set of spring packs in the middle (defined as the first spring pack) can be fixed, while the spring packs on both sides (defined as the second spring packs) can be moved away from the first spring pack when the mattress is in use. At this time, the first spring pack located on the outermost side can be partially located on the outside of the first slide 52 (second slide 57), so that the spring packs can support a wider distance. When the mattress needs to be stored, the second spring packs can be moved closer to the first spring packs, and all the spring packs can be stored within the range of the first slide 52 (second slide 57), so that they can be stored according to the size of the first slide 52 (second slide 57), thereby reducing the storage volume of the mattress.

[0059] In order to control the movement of the spring pack, such as Figure 4 and Figures 6-7 As shown, multiple sets of transmission mechanisms 6 are provided at the bottom of the base 51, which provide the power for the movement of the spring pack at the corresponding position.

[0060] The transmission mechanism 6 includes a bracket 69 fixedly installed at the bottom of the base 51, a motor 65 fixedly installed on the bracket 69, and a first pulley 66 fixedly installed at the output end of the motor 65, so that the first pulley 66 is adapted to rotate under the drive of the motor 65.

[0061] Meanwhile, two sets of transmission seats 61 are fixedly installed at the bottom of the base 51. A transmission shaft 62 is rotatably installed between the two sets of transmission seats 61. A second pulley 67 is fixedly installed at the middle position of the transmission shaft 62. A belt 68 is provided between the first pulley 66 and the second pulley 67 for transmission. Thus, the second pulley 67 is adapted to rotate under the drive of the first pulley 66 and synchronously drive the transmission shaft 62 to rotate.

[0062] Meanwhile, a connecting seat 56 is fixedly installed on each set of spring packs, and a long groove 511 is provided on the base 51. The connecting seat 56 is suitable for threaded connection with the drive shaft 62 through the long groove 511.

[0063] It should be noted that the drive shaft 62 is provided with threads of opposite helical direction on both sides (not shown in the figure), and the connecting seat 56 is connected to the corresponding thread. Thus, when the drive shaft 62 rotates, the connecting seats 56 on both sides can move closer or further away from each other synchronously, thereby driving the corresponding spring packs to move closer or further away from each other.

[0064] In summary, when the mattress needs to be compressed into a roll, the transmission mechanism 6 drives the spring packs to move closer together, thereby reducing the width of the mattress. Although the size of the outer shell of the mattress remains unchanged, the outer shell is made of soft material, which makes it easy to compress and thus makes the mattress roll smaller, making it suitable for smaller apartments or narrow environments such as elevators / hallways.

[0065] When the mattress needs to be unfolded for use, the transmission mechanism 6 drives the spring packs to move away from each other, thereby restoring the mattress to its normal size for easy use.

[0066] Furthermore, in order to control the transmission mechanism 6, such as... Figure 2 and Figure 5 As shown, a socket 13 is provided on the bottom frame 1. The socket 13 is suitable for connection to a power source to supply power to the motor 65. At the same time, a switch 12 is provided on the bottom frame 1. The switch 12 is used to control the forward and reverse rotation of the motor 65, so as to facilitate the control of the spring packs to move closer or further apart, thereby allowing the mattress to be in different states.

[0067] In order to adjust the elasticity of the spring pack to suit the needs of different people, such as Figure 3 and Figure 6 As shown, multiple sets of steel wire wheels 63 are fixedly installed on the drive shaft 62. Steel wire 64 is wound on the steel wire wheels 63. The free end of the steel wire 64 is fixedly installed to the bottom of the second slide 57. When the steel wire wheels 63 are wound, the steel wire 64 can be driven to wrap around the steel wire wheels 63, thereby reducing the distance between the second slide 57 and the first slide 52. At this time, the spring 53 is compressed more tightly, thereby increasing the hardness of the spring 53 and thus increasing the hardness of the mattress.

[0068] Conversely, when the wire wheel 63 unwinds, it can cause the wire 64 to disengage from the wire wheel 63. Then, under the action of the spring 53, the distance between the second slide 57 and the first slide 52 increases. At this time, the spring 53 is relaxed, thereby reducing the hardness of the spring 53 and thus reducing the hardness of the mattress.

[0069] Furthermore, the winding action of the wire wheel 63 can be correlated with the movement of the spring packs on both sides moving closer together. Thus, when it is necessary to increase the firmness of the mattress, the spring packs on both sides can be moved closer together, thereby making the spring packs closer together and thus increasing the firmness of the mattress faster.

[0070] It should be noted that the above-mentioned adjustment of mattress firmness is a minor adjustment, so the movement of the spring packs is small and will not affect the overall layout of the spring packs.

[0071] To ensure that spring 53 moves more stably during compression of the coil and adjustment of its stiffness, such as... Figures 8-9As shown, a telescopic mechanism 7 is provided between the first spring seat 54 and the second spring seat 55. The telescopic mechanism 7 includes a top rod 73 fixedly installed at the bottom of the second spring seat 55. The top rod 73 has a second cavity (not shown in the figure) inside. A middle rod 72 is vertically slidably arranged inside the second cavity. At the same time, a second boss 722 is provided on the top of the middle rod 72. The second boss 722 is used to prevent the middle rod 72 from slipping out of the second cavity.

[0072] Meanwhile, the middle rod 72 has a first cavity (not shown in the figure) inside, and a bottom rod 71 is slidably disposed in the first cavity. A first boss 711 is provided on the top of the bottom rod 71 to prevent the bottom rod 71 from slipping out of the first cavity. The bottom of the bottom rod 71 is fixedly installed with the first spring seat 54. Thus, when the spring 53 is compressed or released, the middle rod 72 can slide inside the top rod 73, and the bottom rod 71 can slide inside the middle rod 72. This prevents the first spring seat 54 and the second spring seat 55 from becoming misaligned, thereby making the spring 53 move more stably when compressing the coil and adjusting the hardness.

[0073] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
