Description

Technical Field

[0001] The invention relates to the technical field of carpets, in particular to the technical field of anti-collapse carpets. Background Art

[0002] Carpet is a floor covering made of natural fibers such as cotton, linen, wool, silk and grass yarn, or chemical synthetic fibers that are knitted, planted or woven by hand or mechanical processes. People can lay carpets on the floor to adjust the floor texture, soundproof and reduce noise, keep warm and insulate, reduce the risk of accidental falls, reduce floor wear and divide space.

[0003] During production, factories usually install sponge pads in the core of carpets to improve the elasticity of carpets, thereby improving the foot feel of the carpet on the one hand and alleviating the vibration of the foot on the ground on the other hand (effectively reducing noise such as footsteps and furniture movement, and improving the indoor acoustic environment), such as the car carpet sound insulation pad with publication number CN106541873A, the carpet with announcement number CN206197698U and a digital carpet with publication number CN101766431A; in addition, some factories choose to use multiple layers of non-woven fabrics in the core of the carpet instead of sponge pads.

[0004] However, as the carpet ages, it may begin to sag, especially in areas that are subject to heavy pressure, which can reduce its comfort and overall aesthetics. Summary of the invention

[0005] The purpose of the present invention is to solve the problems in the prior art and to provide an anti-collapse carpet with better anti-collapse ability.

[0006] To achieve the above-mentioned purpose, the present invention proposes an anti-collapse carpet, comprising a carpet surface layer, a carpet core and a carpet base, wherein the carpet surface layer and the carpet base are detachably connected to the carpet core at the upper and lower sides respectively, and the carpet core has an arc bar group composed of a plurality of elastic arc bars with C-shaped cross-sections, wherein the elastic arc bars of the arc bar group are arranged in parallel in sequence along a horizontal plane and open toward the top surface and / or the bottom surface.

[0007] Preferably, isolation sealing sheets are installed on the upper and lower sides of the arc bar group respectively.

[0008] Preferably, the arc strip group further installs elastic auxiliary support tubes in the mouths of the elastic arc strips, and each of the elastic auxiliary support tubes has an outer tube fixed to one side of the sealing sheet and the elastic arc strip.

[0009] Preferably, the cross section of each outer tube is elliptical and the long axis is perpendicular to the upper and lower sealing sheets, and each outer tube has a plurality of inner tubes arranged in sequence along the long axis.

[0010] Preferably, elastic auxiliary limiting members are provided between the upper and lower sealing sheets and along each elastic arc strip at intervals, and each elastic auxiliary limiting member can limit the shortest distance between the upper and lower sealing sheets at its respective position.

[0011] Preferably, each of the elastic auxiliary limiting members is composed of an inner shell and an outer shell connected inner and outer at one end, and an elastic plug fixed in the inner shell, and each of the elastic auxiliary limiting members fixes the other end of the inner shell and the outer shell to the upper and lower side sealing plates.

[0012] Preferably, each of the elastic auxiliary limiting members is provided with an external sliding groove and an inner flange which can be slidably connected to each other on the inner shell and the outer shell respectively.

[0013] Preferably, each of the elastic auxiliary limiting members is respectively provided with an outer convex edge located on the upper end of the external slide groove on the inner shell.

[0014] Preferably, the carpet surface layer and the carpet base are detachably connected to the carpet core by means of Velcro, snaps, sutures or straps.

[0015] Preferably, the bottom surface of the carpet base is also provided with an anti-slip layer.

[0016] Beneficial effects of the present invention: 1) By using a group of curved strips composed of several elastic curved strips with a C-shaped cross section as a supporting structure between the carpet surface layer and the carpet base, it is not only easier to restore the original shape (i.e., the carpet is not prone to collapse or creases) compared to the traditional carpet core made of sponge pads or multi-layered non-woven fabrics, but also can keep the carpet relatively light (easy to transport and store) and breathable; 2) By making the carpet surface layer and the carpet base detachably connected to the carpet core at the upper and lower sides, the user can rotate and turn the carpet core regularly for use. This can evenly distribute the pressure on the carpet to a certain extent and extend the service life of the carpet core (preventing the carpet core from being locally stressed and collapsing for a long time). On the other hand, the carpet core can also be replaced separately. 3) By installing elastic auxiliary support tubes composed of an outer tube with an elliptical cross section and inner tubes arranged in sequence along the long axis in the outer tube at the mouth of each elastic arc strip, each elastic auxiliary support tube can be used to provide directional internal support to the elastic arc strip, so that each elastic arc strip can maintain its original shape for a longer period of time; 4) By installing a plurality of elastic auxiliary limiting members between the upper and lower sealing sheets, which are respectively formed by an inner shell and an outer shell which are connected inner and outer at one end, and an elastic plug fixed in the inner shell, the relative slip between the inner shell and the outer shell and the elastic contraction of the elastic plug itself can be utilized to ensure that the elastic auxiliary limiting member has a certain elasticity to deform with stepping, and the supporting effect between the inner shell and the outer shell can be utilized to limit the closest distance between the upper and lower sealing sheets at the stepping position, thereby avoiding excessive flattening of the elastic arc strip and the elastic auxiliary supporting tube.
