Description

Technical Field

[0001] The present application relates to the technical field of compressed roll-pack mattresses, and specifically to a compressed roll-pack mattress. Background Art

[0002] Mattresses are a common household item. Existing mattresses are generally made of springs, and then have frames connected to the upper and lower edges of the mattresses to evenly distribute the force on the mattress. Although the mattress is light, it is bulky, which takes up a lot of space during transportation and increases transportation costs. To solve the above problem, the existing method is to compress the mattress first, then roll it up, and then pack it in boxes for transportation.

[0003] The compressed roll-pack mattress is compressed to 1 / 3 of its original volume (thickness is compressed from 20cm-26cm to 2cm-5cm) using professional equipment, rolled into a cylindrical shape and sealed with plastic film. After unpacking, the mattress will automatically rebound to its original size within a few minutes, making it easy to install.

[0004] For example, the patent with publication number CN221129402 U specifically discloses a vacuum compression mattress that is easy to roll up. This patent connects the cloth covers arranged vertically and horizontally through positioning cloth, so that the axial direction of the spring compression can be easily limited, avoiding the problem of spring tilting and compression deformation, which causes inconvenience in subsequent rolling up and damages the overall reset ability of the mattress. Secondly, by arranging a first storage cylinder, a second storage cylinder and a third storage cylinder between the first frame and the second frame, the first frame and the second frame can be slidably limited by the first storage cylinder, the second storage cylinder and the third storage cylinder. In this way, the first frame and the second frame can further improve the axial stability and compression performance of the first frame and the second frame and even the edge springs on the basis of avoiding the force dispersion of many springs and effectively avoiding the damage or collapse of the edge springs, further facilitating the subsequent compression and rolling up of the mattress, and through multi-layer limited compression, it can also adapt to the final axial compression height of the springs;

[0005] Although the above patent achieves the rolling of the mattress in the length direction, it does not achieve a certain degree of compression in the width direction of the mattress, so that the rolled mattress still has a long size. When entering some small apartments or narrow elevator / corridor environments, the long size still makes the mattress difficult to turn around, so it is necessary to provide a compressed rolled mattress to solve the above problem.

[0044] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0045] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0046] like Figure 1-Figure 2 As shown, the present application provides a compressed rolled mattress, including a bottom frame 1, which serves as a support portion of the mattress and is primarily used to protect the internal structure of the mattress and enhance air permeability and wear resistance. The bottom frame 1 is generally made of non-woven fabric or breathable mesh fabric, and a first air hole 11 is provided at the bottom of the bottom frame 1. The first air hole 11 is primarily used to enhance the overall air permeability of the mattress.

[0047] A fence 2 is provided at the upper end of the bottom frame 1. A first zipper (not shown) is provided at the connection between the fence 2 and the bottom frame 1. The first zipper facilitates the connection and removal of the fence 2 from the bottom frame 1. The fence 2 is mainly composed 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, touch and initial breathability of the mattress. The top frame 3 is generally made of cotton, linen, knitted fabric and other materials, focusing on skin-friendliness and breathability. A second zipper (not shown in the figure) is provided at the circle where the top frame 3 is connected to the enclosure 2. The second zipper facilitates the connection and removal of the top frame 3 and the enclosure 2 for subsequent cleaning.

[0049] Continue to refer Figure 1-Figure 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 hardness, fit, and wrapping feeling 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 is breathable and anti-mite, and can provide elastic support. In addition, a second air hole 41 is opened on the top plate 4. The second air hole 41 mainly cooperates with the first air hole 11 to increase the overall air flow of the mattress.

[0050] Thus, the above-mentioned bottom frame 1, the surrounding barrier 2, and the top plate 4 constitute the external overall structure of the mattress, hereinafter referred to as the outer shell, and a accommodating space is formed inside the above-mentioned three. A support mechanism 5 is provided inside the accommodating space. The support mechanism 5 is used to bear the weight of the human body, disperse the pressure, and maintain the natural curvature of the spine. In this application, the support mechanism 5 mainly adopts independent pocket springs, so that the support mechanism 5 is silent and anti-interference. Each spring operates independently, which is suitable for people who wake up easily. As for the structure of the support mechanism 5 and the independent pocket springs, the details will be described later.

[0051] In order to facilitate the compression and rolling of the mattress, Figure 3-Figure 4 As shown, the support mechanism 5 includes a base 51 provided at the bottom of the bottom frame 1. The base 51 can be made of latex material to facilitate compression and rolling. A plurality of elastic components (not shown) are provided on the base 51. The plurality of elastic components are evenly arranged along the length direction of the mattress. At the same time, each two adjacent elastic components have a folding gap of the same size (not shown). The folding gap serves as the folding position when the mattress is rolled.

[0052] It is understood that when the mattress is wrapped with a vacuum film and compressed by vacuuming, the multiple sets of elastic components can be folded along the folding gaps to facilitate integration of the elastic components into a roll. Since a dedicated folding gap is provided in the present application, the mattress is easier to store into a roll, and the size can be fixed, thereby facilitating subsequent packaging.

[0053] In the present application, the size of the elastic components can be set 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 assembly includes a first slide 52 fixedly mounted on a base 51. Two sets of first guide rails 521 are provided on the first slide 52 along the width direction of the mattress. Multiple sets of first spring seats 54 are slidably provided on both sides of the first guide rails 521. The first spring seats 54 are provided with first matching grooves 541 that match the first guide rails 521. Therefore, through the matching of the first guide rails 521 and the first matching 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, and 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 provided on both sides of the second guide rails 571. The second spring seats 55 are arranged corresponding to the first spring seats 54. At the same time, a second matching groove 551 that matches the second guide rails 571 is provided on the second spring seat 55, so that through the matching of the second guide rails 571 and the second matching groove 551, the multiple sets of second spring seats 55 can slide along the second guide rails 571, and 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 therebetween form a whole. For ease of explanation, the whole is defined as a spring pack, which can be regarded as an independent pocket spring. Thus, driven by the first spring seat 54 and the second spring seat 55, the spring pack can move along the width direction of the mattress.

[0057] It should be noted that the first slide 52 and the second slide 57 are both made of spring steel, so that they have a certain degree of rigidity to maintain the stability of the spring assembly. At the same time, the lengths of the first slide 52 and the second slide 57 are the same and smaller 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 mattress will be slightly reduced, so that it can be adapted to smaller apartments or environments with narrow elevators or corridors.

[0058] In actual use, multiple groups of spring packs are symmetrically arranged on both sides. In this embodiment, multiple groups of spring packs are arranged in odd groups, so that the group of spring packs located in the middle (defined as the first spring pack) can be fixed, and the spring packs located on both sides (defined as the second spring packs) can be 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 outside the first slide 52 (second slide 57), so that the spring pack can support a wider distance. When the mattress needs to be stored, the second spring pack can be moved closer to the first spring pack, 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 Figure 6-Figure 7 As shown, multiple transmission mechanisms 6 are provided at the bottom of the base 51, and the transmission mechanisms 6 provide power for the spring packs at corresponding positions to move;

[0060] The transmission mechanism 6 includes a bracket 69 fixedly mounted on the bottom of the base 51, a motor 65 fixedly mounted on the bracket 69, and a first pulley 66 fixedly mounted on the output end of the motor 65, so that the first pulley 66 is suitable for rotating under the drive of the motor 65;

[0061] At the same time, two sets of transmission seats 61 are fixedly installed at the bottom of the base 51, and a transmission shaft 62 is rotatably installed between the two sets of transmission seats 61. A second pulley 67 is fixedly installed in the middle position of the transmission shaft 62. A belt 68 is provided between the first pulley 66 and the second pulley 67, so that the second pulley 67 is suitable for rotating under the drive of the first pulley 66 and synchronously driving the transmission shaft 62 to rotate;

[0062] At the same time, a connecting seat 56 is fixedly installed on each set of spring packs, and a long slot 511 is provided on the base 51. The connecting seat 56 is suitable for passing through the long slot 511 and being threadedly connected to the transmission shaft 62;

[0063] It should be noted that threads with opposite spiral directions (not shown in the figure) are provided on both sides of the transmission shaft 62, and the connecting seats 56 are connected to the corresponding threads. Therefore, when the transmission shaft 62 rotates, the connecting seats 56 on both sides can synchronously move closer to or farther from each other, thereby driving the corresponding spring packs to move closer to or farther from each other.

[0064] In summary, when the mattress needs to be compressed and rolled, the transmission mechanism 6 drives the spring packs 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 a soft structure that facilitates compression, thereby making the size of the mattress roll smaller, making it suitable for smaller apartments or narrow elevators or corridors.

[0065] When the mattress needs to be unfolded for use, the spring packs are driven away from each other by the transmission mechanism 6, so that the mattress returns to its normal size for easy use.

[0066] Furthermore, in order to control the transmission mechanism 6, as shown in FIG. Figure 2 and Figure 5 As shown, a socket 13 is provided on the bottom frame 1, and the socket 13 is suitable for connecting to a power source to power the motor 65. At the same time, a switch 12 is provided on the bottom frame 1, and the switch 12 is used to control the forward and reverse rotation of the motor 65, thereby facilitating the control of the spring packs to move closer to or farther away from each other, thereby allowing the mattress to be in different states.

[0067] In order to adjust the elasticity of the spring bag to meet the needs of different groups of people, such as Figure 3 and Figure 6 As shown, multiple sets of wire wheels 63 are fixedly mounted on the transmission shaft 62. The wire wheels 63 are wound with wires 64. The free ends of the wires 64 are fixedly mounted to the bottom of the second slide 57. When the wire wheels 63 are wound, the wires 64 are driven to be wound around the wire wheels 63, thereby reducing the distance between the second slide 57 and the first slide 52. At this time, the springs 53 are compressed more tightly, thereby increasing the hardness of the springs 53 and thus increasing the hardness of the mattress.

[0068] On the contrary, when the wire wheel 63 is unwound, the wire 64 can be driven to disengage from the wire wheel 63, and then under the action of the spring 53, the distance between the second slide 57 and the first slide 52 becomes larger. At this time, the spring 53 is relaxed, thereby reducing the hardness of the spring 53 and reducing the hardness of the mattress.

[0069] Furthermore, the winding action of the wire wheel 63 can be matched with the action of the spring packs on both sides moving closer to each other, so that when the hardness of the mattress needs to be increased, the spring packs on both sides can be moved closer to each other, thereby making the hardness of the mattress increase faster.

[0070] It should be noted that the above-mentioned adjustment of the mattress hardness is a fine-tuning, so the movement of the spring pack is small, which will not affect the overall layout of the spring pack.

[0071] In order to make the spring 53 move more stably when it is compressed and rolled and the hardness is adjusted, Figure 8-Figure 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 mounted on the bottom of the second spring seat 55. A second cavity (not shown) is provided inside the top rod 73. A middle rod 72 is vertically slidably provided inside the second cavity. 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] At the same time, a first cavity (not shown in the figure) is provided inside the middle rod 72, and a bottom rod 71 is slidably provided in the first cavity. At the same time, a first boss 711 is provided on the top of the bottom rod 71. The first boss 711 is used 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, so that when the spring 53 is compressed or relaxed, the middle rod 72 can slide inside the top rod 73, and the bottom rod 71 can slide inside the middle rod 72, so that the first spring seat 54 and the second spring seat 55 will not be misaligned, thereby making the spring 53 move more stably when compressed, rolled and the hardness adjusted.

[0073] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
