Description

Technical Field

[0001] This utility model belongs to the field of furniture, and specifically relates to a mattress and sofa bed adapted to sofa beds. Background Technology

[0002] Existing sofa beds come in two structures: one is a flip-up type, where the flipping process requires overcoming the weight of the backrest / mattress, especially in models with thick mattresses (such as spring mattresses). Flipping requires lifting upwards or pressing downwards on the backrest, which can be difficult for women, the elderly, or children to operate alone due to insufficient strength, potentially causing them to get stuck or even tilt forward and lose balance due to uneven force. The other type is a pull-out type, where the mattress must be hidden under the seat or in the pull-out frame at the bottom, limited by the height of the storage space. Therefore, the existing sofa bed structures are inefficient and inconvenient to use. Utility Model Content

[0003] To address the problem of inconvenient mattress use caused by the unreasonable structure of existing sofa beds, this utility model provides a mattress and sofa bed adapted to sofa beds, which provides multiple uses by setting a first split mattress, a second split mattress and a third split mattress.

[0004] The technical solution adopted by this utility model is as follows: A mattress adapted to a sofa bed includes a first split mattress, a second split mattress, and a third split mattress. The first split mattress has a first soft hook on its side, the second split mattress has a second soft hook and a first hard hook on its side, and the third split mattress has a second hard hook. The connection between the first split mattress and the second split mattress is achieved through the cooperation of the first soft hook and the first hard hook. The connection between the second split mattress and the third split mattress is achieved through the cooperation of the second soft hook and the second hard hook. In use, the first split mattress can be placed above the second split mattress and the third split mattress, or the first split mattress can be connected to the second split mattress, or the first split mattress, the second split mattress, and the third split mattress can be connected sequentially.

[0005] This application provides a mattress adapted to a stretchable sofa bed. When placed horizontally, the first and second mattress units can be connected together, or the first, second, and third mattress units can be connected together. To increase the mattress thickness, the second and third mattress units can be placed on the lower layer, and the first mattress unit on top. The combination of hard and soft hooks allows for easy, reliable, and convenient connection between the first, second, and third mattress units. Furthermore, the mattress width can be adjusted as needed; all three mattress units can be unfolded simultaneously, or only two can be used. The first mattress unit can also be stacked on top of the second and third mattress units, offering diverse usage options.

[0006] Furthermore, the first hard hook and the second hard hook are the stiff side of the Velcro, and the first soft hook and the second soft hook are the soft side of the Velcro.

[0007] Furthermore, the width of the first split pad is the sum of the widths of the second and third split pads, so that when the first split pad is placed above the second and third split pads, the entire mattress has the same thickness.

[0008] Furthermore, the bottom of the first split pad is provided with elastic bands, which are used to secure it downwards. When folded up, the first split pad is tightened downwards and fixed to the split pad below using the elastic bands at its four bottom corners.

[0009] Furthermore, the elastic band has four sections, located below the four corners of the first split pad.

[0010] Furthermore, the distance between the first soft hook and the edge of the first split pad is A, where A is 0.5-2cm; the distance between the second soft hook and the edge of the second split pad is B, where B is 0.5-2cm.

[0011] Furthermore, the width of the first hard buckle is 3-7cm, and the width of the second hard buckle is 3-7cm.

[0012] Furthermore, when the first, second, and third split pads are connected in sequence, the overall width is 120-150cm.

[0013] A sofa bed includes a bed frame and a mattress, wherein the mattress is the aforementioned sofa bed-compatible mattress.

[0014] The beneficial effects of this utility model are as follows: This application relates to a mattress and sofa bed adapted for use with sofa beds. When placed in parallel, the first and second split mattresses, or the first, second, and third split mattresses, can be connected using Velcro handles. To increase the mattress's thickness, the second and third split mattresses can be placed on the lower layer, and the first split mattress on the upper layer. The combination of hard and soft hooks and loops allows for easy, reliable, and convenient connection of the first, second, and third split mattresses. Furthermore, the width of the entire mattress can be adjusted as needed; all three split mattresses can be unfolded simultaneously, or only two can be used. The first split mattress can also be stacked on top of the second and third split mattresses, offering diverse usage modes. Attached Figure Description

Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of this utility model.

[0024] Example 1

[0025] A mattress that fits a sofa bed, such as Figures 1 to 4 As shown, the device includes a first split pad 1, a second split pad 2, and a third split pad 3. The first split pad 1 has a first soft hook-and-loop fastener 11 on its side. The second split pad 2 has a second soft hook-and-loop fastener 21 and a first hard hook-and-loop fastener 22 on its side. The third split pad 3 has a second hard hook-and-loop fastener 31. The connection between the first split pad 1 and the second split pad 2 is achieved through the cooperation of the first soft hook-and-loop fastener 11 and the first hard hook-and-loop fastener 22. The connection between the second split pad 2 and the third split pad 3 is achieved through the cooperation of the second soft hook-and-loop fastener 21 and the second hard hook-and-loop fastener 31.
