RELATED APPLICATIONS

This application claims priority to Chinese patent application number 202311728049.4, filed on Dec. 14, 2023. Chinese patent application number 202311728049.4 is incorporated herein by reference.

FIELD OF THE DISCLOSURE

The present disclosure relates to the field of furniture, and in particular relates to soft pads or bed mattresses for furniture.

BACKGROUND OF THE DISCLOSURE

Soft pads are pillow-like supporters, also known as “lining mattresses,” and various household items, such as bed pads and sofas, are included. An elastic mattress is usually placed on a lower side of the soft pad to provide elasticity for supporting the soft pad, and the elastic mattress and the soft pad usually form a composite integrated structure. Typically, a spring bed comprises an elastic mattress core and an outer cover of the soft pad is wrapped an outer peripheral side of the elastic mattress core. Generally, the outer cover of the soft pad is fixed by sewing or adhesive, creating a non-detachable composite spring mattress.

In order to satisfy sanitary requirements for use of the soft pad, an additional cover is usually placed on the soft pad of the composite spring mattress during use so as to satisfy requirements for daily cleaning. However, after long-term use of the soft pad, even if the cover on an outer layer can be cleaned, stains penetrating into the soft pad through the cover remain uncleanable, resulting in sanitary issues after the long-term use.

In the existing technologies, an outer cover of the soft pad is selected to be converted into an open-style structure having a continuous zipper, allowing the elastic mattress core to be separated from the outer cover during cleaning. However, most of elastic mattress cores, especially elastic mattress cores in bed mattresses, are integrated, large, and cumbersome, resulting in removal of the outer cover being very inconvenient. Difficulty in assembly and disassembly directly affects a frequency in cleaning the outer cover during daily life, and there are still cases that are not easily cleaned.

Thus, there is a need for improving a connection design between the soft pads so as to be not affected by a size of the elastic mattress core. Assembly and disassembly of the soft pads as a whole is convenient for easy cleaning due to a reasonable design arrangement even without relocation of the elastic mattress core.

Referring to FIGS. 1-6, this embodiment provides a connecting structure for a soft pad layer 2 of an elastic mattress, and the connecting structure comprises a spring core consisting of one or more spring modules 1 and the soft pad layer 2 laid on the spring core.

Each of the one or more spring modules 1 comprises a plurality of springs 11 arranged staggered or array arrangements, and the plurality of springs 11 are individual springs 11 that are wrapped by cloth bags or other flexible materials to be pre-compressed. Adjacent springs 11 of the plurality of springs 11 are connected by one or more connecting members 3 or connecting portions extending out from the flexible material. In this embodiment, the one or more spring modules 1 are connected by the one or more connecting members 3 to form an independent spring structure, and the adjacent springs 11 independently provide elasticity to have less influence on each other and to be less involved with each other. The staggered or array arrangements are used to achieve a close arrangement of the plurality of springs 11 in the elastic mattress.

Specifically, the adjacent springs 11 are connected by the one or more connecting members 3 disposed on any position, except upper ends, on the plurality of springs 11, and the upper ends of the plurality of springs 11 are not constrained by the one or more connecting members 3. The upper ends of the plurality of springs 11 define an elastic stressing surface, so that individuals of the plurality of springs 11 become an integrated body without a rigid frame. Individual independence of the plurality of springs 11 is not affected or is less affected at the same time, and an overall elasticity of the elastic mattress can be achieved without a thick sponge layer or other soft pad.

After the one or more spring modules 1 formed by the abovementioned structure define the spring core, a thick sponge layer similar to that of a traditional spring mattress and for ensuring integrality is not needed. Merely the soft pad layer 2 that is flexible, such as made of duck down, goose down, or latex, needs to be added to the elastic mattress to be used as a spring bed mattress 5, and a thickness of the soft pad layer 2 is not more than 10 cm, generally 5-6 cm.

The one or more connecting members 3 in this embodiment can be sleeved on the cloth bags or the flexible materials of the plurality of springs 11. The one or more connecting members 3 comprise the connecting portions, and adjacent connecting portions of the connecting portions are connected by a buckled connection with each other, a misaligned engagement, or overlapping using a third member.

When the one or more spring modules 1 in this embodiment are used to form the bed mattress 5, two adjacent springs 11 of the plurality of the springs 11 of the one or more spring modules 1 in this embodiment are engaged to be in a misaligned arrangement by an engaged connecting portion of the connecting portions of the one or more connecting members 3, and the one or more connecting portions are engaged with each other. Corresponding connecting members 3 of the one or more connecting members 3 on corresponding springs 11 of the plurality of springs 11 on an outer periphery of the one or more spring modules 1 comprise through holes 32. When a mattress core of the bed mattress 5 is formed by combining the one or more spring modules 1, a fixing band 4 passes through the through holes 32 to bind the one or more spring modules 1 and the plurality of springs 11 therein in series along the outer periphery of the one or more spring modules 1, forming the mattress core (i.e., the spring core) of the bed mattress 5.

The soft pad layer 2 is laid on the mattress core of the bed mattress 5 to form the integrated bed mattress 5 for use. The soft pad layer 2 is detachably connected to the spring core formed by the one or more spring modules 1, and the soft pad layer 2 is laid on an upper side or the upper side and a periphery of the one or more spring modules 1 to form a wrapped or semi-wrapped form without wrapping one or more bottoms of the one or more spring modules 1. When the soft pad layer 2 is disassembled and cleaned, the operation can be accomplished without lifting up the spring core, so as to facilitate disassembling and cleaning.

Specifically, in this embodiment, all sides of the soft pad layer 2 comprise short peripheral edges 21, and the short peripheral edges 21 on a single side comprise a plurality of fastening positions 22. Corresponding ones of the one or more connecting members 3 on the outer periphery of the one or more spring modules 1 comprise fastening points 31 corresponding to the plurality of fastening positions 22. The plurality of fastening positions 22 cooperate with the fastening points 31 by buckling to enable the soft pad layer 2 to be alternatively wrapped on or detached from the one or more spring modules 1.

The plurality of fastening positions 22 have lug-sheet shaped structures. When a buckled connection of the plurality of fastening positions 22 and the fastening points 31 is performed, the lug-sheet shaped structures enable the plurality of fastening positions 22 to have certain tensile deformations to be perfectly buckled to the fastening points 31. In addition, after being buckled, the certain tensile deformations form a certain pulling force to further tension the soft pad layer 2 in advance to form a wrapping effect, avoiding a deviation phenomenon of the soft pad layer 2 during use.

In this embodiment, the plurality of fastening positions 22 are disposed at intervals of 1-3 springs 11 of the plurality of springs 11, so as to enable the soft pad layer 2 to perfectly wrap the one or more spring modules 1, and a stress of the buckled connection is balanced, so that an edge of the soft pad layer 2 does not raise or curl.

It should be noted that the short peripheral edges 21 disposed on all sides of the soft pad layer 2 can be replaced with short pulling straps. The short peripheral edges 21 or the short pulling straps in this embodiment are not limited to the structures involved in this embodiment and can be replaced with one or more elastic pulling straps, one or more drawstrings, and so on, as an equivalent substitutive structure to tension the soft pad layer 2 in advance to be buckled to the one or more spring modules 1.

The lug-sheet shaped fastening positions 22 each comprise a female fastener 311 or a male fastener 221 of a snap fastener. An end surface of a corresponding connecting member 3 of the one or more connecting members 3 on the outer periphery of the one or more spring modules 1 is disposed with the female fastener 311 or the male fastener 221 of the snap fastener. The snap fastener is commonly known as a snap button, a spring fastener, or a pair-up fastener. The snap fastener is defined by two S-shaped springs 110. The female fastener 311 is a wide edge configured to be engraved with patterns with a middle part being a hole, and two sides of the hole are disposed with the two S-shaped springs 110 that are parallel. A middle part of the male fastener 221 protrudes to form a round point, and the round point is pressed into the hole of the female fastener 311 to be then tightly clamped by the two S-shaped springs 110, resulting in an open-close force to realize a fixation.
