Inside the rectangle, multiple rows of bagged main spring groups are arranged side by side in the width direction of the rectangle. Any two adjacent rows among the rows of bagged main spring groups are connected to each other. There are multiple vertically placed rectangular frames. These rectangular frames are arranged side by side in the length direction of the rectangle and are sleeved on the rectangle at intervals. Multiple parts of each row of bagged main springs are fixedly installed on these rectangular frames respectively; each row of bagged main spring groups has multiple bagged main springs. Any two of these bagged main springs that are adjacent in the length direction of the rectangle have their lower ends of the bags not connected to each other while their upper ends of the bags are fixedly connected to each other so that one of the two bagged main springs can flip upward relative to the other.

Similarly, it can be known that other bagged main springs can also flip around the corresponding connection points. Therefore, this mattress can be rolled up.

Description

Technical Field

[0001] The present invention relates to the field of mattresses, in particular to a rollable spring mattress. Background Art

[0002] In the prior art, a spring mattress is in an overall cuboid shape. Inside the cuboid, there are multiple rows of springs arranged side by side. A mattress frame is provided on the sides of the cuboid, and the springs are fixed to the mattress frame. When a person sits on the edge of the mattress, the mattress frame provides a supporting force to the person, preventing the entire weight of the person from being borne by the local springs at the edge of the mattress, which may cause these local springs to be crushed and unable to recover elastically, resulting in the phenomenon of "edge collapse". The defect of the prior art is that since the mattress frames are provided on all sides of the cuboid, the mattress body cannot be rolled up, making transportation and storage inconvenient, that is, "rolling up" and "preventing edge collapse" cannot be achieved simultaneously. Summary of the Invention

[0003] The present invention aims to provide a rollable spring mattress that can prevent edge collapse, which can be normally rolled up and does not collapse at the edge.

[0004] A rollable spring mattress that can prevent edge collapse, the mattress body is in a cuboid shape. Inside the cuboid, multiple rows of bag-type main spring groups are arranged side by side in the width direction of the cuboid. Any two adjacent rows among the rows of bag-type main spring groups are connected to each other. A plurality of vertical rectangular frames are provided, and these rectangular frames are arranged side by side in the length direction of the cuboid and are sleeved on the cuboid at intervals. Multiple parts on each row of bag-type main springs are respectively fixed to these rectangular frames; each row of bag-type main spring groups has a plurality of bag-type main springs. Any two of these bag-type main springs that are adjacent in the length direction of the cuboid have their lower ends of the bags not connected to each other while their upper ends of the bags are fixedly connected to each other so that one of the two bag-type main springs can flip upward relative to the other.

[0005] Further, specifically, the number of rectangular frames is the same as the number of bag-type springs on each row of bag-type springs, and all the bag-type springs on each row of bag-type springs are respectively fixed to these rectangular frames.

[0006] Further, inside the cuboid, multiple rows of bag-type auxiliary spring groups are also arranged side by side in the width direction of the cuboid. The multiple rows of bag-type auxiliary spring groups and the multiple rows of bag-type main spring groups are arranged alternately at intervals; all the bag-type auxiliary springs in each row of bag-type auxiliary spring groups are respectively aligned with all the connection parts of the adjacent bag-type main spring groups, and the upper supporting surfaces of the bag-type auxiliary springs and the bag-type main springs are at the same height.

[0007] Further, between two adjacent bag-type auxiliary spring groups, a plastic cross beam is provided across the above-mentioned connection part between two bag-type auxiliary springs that are adjacent in the width direction of the cuboid, and the upper ends of the bags of the two bag-type main springs corresponding to this connection part are respectively fixedly connected to this plastic cross beam.

[0008] Furthermore, in each row of bagged auxiliary spring groups, a rope is provided between any two adjacent bagged auxiliary springs in the length direction of the cuboid, and the rope passes between the two rows of bagged main spring groups. Both ends of the rope are respectively connected to the upper ends of the two bagged auxiliary springs while the lower ends of the two bagged auxiliary springs are not connected to each other, so that one of the two bagged auxiliary springs can be flipped upward relative to the other.

[0009] Furthermore, an anti-collapse elastic member is provided on the outer side of each pocket auxiliary spring in the two rows of pocket auxiliary spring groups located at the long sides of the mattress body. One side of the anti-collapse elastic member is mounted on the pocket auxiliary spring and the other side is mounted on the rectangular frame.

[0010] Furthermore, the anti-collapse elastic part is L-shaped as a whole, the horizontal part is the connecting part, and the vertical part is the deformation part; the anti-collapse elastic part is placed horizontally, the top of the deformation part is connected to the outer part of the bag-type auxiliary spring, and the connecting part is connected to the rectangular frame; the deformation part deforms itself when subjected to vertical downward pressure to provide upward support force.

[0011] Furthermore, specifically, the anti-collapse elastic member is formed by bending the same steel wire, the head of the steel wire goes up in a vertical plane and then turns around and goes down to form a U-shaped deformation portion, then turns from going down to going horizontally, goes horizontally in a horizontal plane and then turns around and goes horizontally to form a U-shaped connecting portion, and this cycle is repeated until at least two deformation portions are formed.

[0012] Furthermore, a torsion spring is provided between two adjacent deformation parts, and two ends of the torsion spring are respectively connected to the two deformation parts to provide a supporting force to the two deformation parts to prevent the two deformation parts from being offset from each other.

[0013] Furthermore, the two heads of the steel wire and the connecting portion are located in the same horizontal plane.

[0014] The beneficial effect is that: since any two adjacent pocket auxiliary springs in the length direction of the rectangular parallelepiped have their lower ends not connected to each other but their upper ends fixed to each other, the two pocket main springs can be turned around the connection; the rectangular frame is connected to the pocket main springs rather than the pocket bodies of the pocket main springs, so it will not hinder the above-mentioned turning, and similarly, it can be known that other pocket main springs can also turn around the corresponding connection, so the mattress can be rolled up. Because a plurality of rectangular frames are arranged side by side in the length direction of the rectangular parallelepiped, these rectangular frames support the pocket main springs, so the mattress is not prone to "collapse".

Detailed implementation mode

[0022] The present invention will be further described in detail below in conjunction with the specific implementation modes.

[0023] As Figure 2 shown, the mattress body 13 is in the shape of a cuboid. Inside the cuboid, multiple rows of bag-type main spring groups are arranged side by side in the width direction of the cuboid. Each row of bag-type main spring groups has multiple bag-type main springs 2. For any two adjacent ones of these bag-type main springs 2 in the length direction of the cuboid, the lower ends of their bag bodies 3 are not connected to each other while the upper ends of their bag bodies 3 are fixedly connected to each other so that one of the two bag-type main springs 2 can flip upward relative to the other. Inside the cuboid, multiple rows of bag-type auxiliary spring groups are arranged side by side in the width direction of the cuboid. The multiple rows of bag-type auxiliary spring groups and the multiple rows of bag-type main spring groups are arranged alternately at intervals; all the bag-type auxiliary springs 4 in each row of bag-type auxiliary spring groups are respectively aligned with all the connection points 15 of the adjacent bag-type main spring groups. The upper support surfaces of the bag-type auxiliary spring 4 and the bag-type main spring 2 are at the same height so that the bag-type auxiliary spring 4 can help the bag-type main spring 2 share part of the weight pressing on the mattress. Among each row of bag-type auxiliary spring groups, a rope 5 is provided between any two adjacent bag-type auxiliary springs 4 in the length direction of the cuboid. The rope 5 passes between two rows of bag-type main spring groups. The two ends of the rope 5 are respectively connected to the upper ends of the two bag-type auxiliary springs 4 while the lower ends of the two bag-type auxiliary springs 4 are not connected to each other, so that one of the two bag-type auxiliary springs 4 can flip upward relative to the other. The specific rolling mark 14 is as Figure 6As shown, the purpose of using the rope 5 is that the rope 5 is flexible and does not hinder the above-mentioned flipping; however, in the non-flipping state, the rope 5 can limit the two bag-type auxiliary springs 4 to prevent them from separating. Among adjacent rows of bag-type auxiliary spring groups, a plastic cross beam 6 is provided across the connection 15 between two adjacent bag-type auxiliary springs 4 in the width direction of the cuboid. The upper ends of the bags 3 of the two bag-type main springs 2 corresponding to the connection 15 are respectively fixed to this plastic cross beam 6. The plastic cross beam 6 can undergo a small amount of deformation when a person sits on it, and it will not make people feel uncomfortable.

[0024] Combined Figure 1 、 Figure 2 and Figure 6 , a plurality of vertically arranged plastic rectangular frames 1 are provided as the mattress frame 12. These rectangular frames 1 are arranged side by side in the length direction of the cuboid and are sleeved on the cuboid at intervals. The number of bag-type springs on each row of bag-type springs is the same as that of the rectangular frames 1. All the bag-type springs on each row of bag-type springs are respectively fixedly installed on these rectangular frames 1. The rectangular frames 1 are arranged at intervals in order to avoid the above-mentioned creases 14, so that the rectangular frames 1 do not hinder the rolling up of the mattress body 13. As Figure 4 and Figure 5 shown, a collapse-preventing spring 7 serving as a collapse-preventing elastic member is provided on the outside of each bag-type auxiliary spring 4 in the two rows of bag-type auxiliary spring groups at the long side of the mattress body 13. The collapse-preventing spring 7 is generally L-shaped. The horizontal part is the connecting part 11, and the vertical part is the deforming part 9; the collapse-preventing elastic member is placed horizontally so that the deforming part 9 is located at the front side and the connecting part 11 is located at the rear side. The top of the deforming part 9 is connected to the outer part of the bag-type auxiliary spring 4, and the connecting part 11 is connected to the rectangular frame 1 (except for the last collapse-preventing spring 7, whose connecting part 11 is located at the front side and is connected to the front rectangular frame 1, and the deforming part 9 is located at the rear side and is connected to the last bag-type auxiliary spring 4); when a person sits on the bag-type auxiliary spring 4 and the collapse-preventing spring 7 between the two rectangular frames 1 at the long side of the mattress body 13, the deforming part 9 of the collapse-preventing spring 7 is subjected to a vertically downward pressure and provides an upward supporting force through its own deformation, sharing a part of the pressure for the bag-type auxiliary spring 4 to avoid "edge collapse". If a person sits at the short side of the mattress body 13, since the person's buttocks are much larger than the bag-type auxiliary spring 4, when the person sits at the short side of the mattress body 13, the person will sit on the rectangular frame 1, and the rectangular frame 1 shares a part of the pressure for the bag-type auxiliary spring 4 to avoid "edge collapse".

[0025] Preferably, as Figure 3As shown, the anti-collapse spring 7 is formed by bending the same steel wire. The head 10 of the steel wire goes up in a vertical plane and then turns down to form a U-shaped deformation part 9, then turns from going down to going horizontally, goes horizontally in a horizontal plane and then turns horizontally to form a U-shaped connecting part 11, and repeats this cycle until at least two deformation parts 9 are formed. A torsion spring 8 is provided between two adjacent deformation parts 9. The two ends of the torsion spring 8 are respectively connected to the two deformation parts 9 to provide support force to the two deformation parts 9 so as to prevent the two deformation parts 9 from being offset from each other when the two deformation parts 9 are subjected to lateral force. The two heads 10 of the steel wire and the connecting part 11 are located in the same horizontal plane, and the three are connected to the rectangular frame 1 together to prevent the heads 10 and the connecting part 11 from being offset from each other after long-term use.

[0026] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
