Description

Technical Field

[0001] This utility model relates to the field of carpets, and in particular to a modular carpet. Background Technology

[0002] With the diversification of social culture, carpets are used more widely in human production and daily life. In order to have good shock absorption, sound insulation and comfortable feel underfoot, carpets are usually made of thick fabrics. However, the thickness of the fabric makes it difficult to put in a washing machine, making cleaning difficult; and when the carpet area is large, the cleaning difficulty is even greater, bringing a poor cleaning experience to the user.

[0003] Currently, in order to solve the problem of carpets being too thick and difficult to clean, many carpets on the market are made thinner. However, thinner carpets have poor shock absorption and sound insulation, resulting in poor texture and comfort. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a modular carpet that can be used alone or in combination and is easy to clean.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] The first aspect of this utility model provides a modular carpet, including...

[0007] The upper blanket body includes the first bonding layer;

[0008] A lower blanket body is used to be laid between the upper blanket body and the object surface, and the lower blanket body includes a second bonding layer;

[0009] The edge region of the first bonding layer extends beyond the second bonding layer to contact the surface of the object and does not overlap with the second bonding layer. The main region of the first bonding layer is detachably connected to the second bonding layer by static friction to prevent relative movement when the upper blanket and the lower blanket are connected.

[0010] The second aspect of this utility model also provides a modular carpet, including...

[0011] The upper blanket body includes a first layer and a first bonding layer located below the first layer;

[0012] The lower blanket body is used to be laid between the upper blanket body and the surface of the object. The lower blanket body includes a second bonding layer and a second layer located below the first bonding layer.

[0013] The edge region of the first bonding layer extends beyond the second bonding layer to contact the surface of the object and does not overlap with the second bonding layer. The main region of the first bonding layer and the second bonding layer are detachably connected by a mechanical interlocking structure to prevent relative movement when the upper blanket and the lower blanket are connected.

[0014] Compared to existing technologies, the modular carpet provided by this invention uses the first bonding layer and the second bonding layer in contact. The static friction or mechanical interlocking structure between them allows them to remain relatively stationary. When a person or animal walks on the carpet, the horizontal force is less than the static friction or mechanical interlocking force, allowing them to continue to remain relatively stationary and preventing separation. Furthermore, the detachable assembly of the two layers allows the upper and lower carpet bodies to be used together or separately as needed. When used together, the carpet thickness is effectively increased, resulting in a carpet with good shock absorption and sound insulation, and higher comfort. When used separately in certain scenarios, either the upper or lower carpet body can be used individually, thus diversifying the application scenarios of the modular carpet and improving its versatility. Furthermore, since the lower carpet is smaller than the upper carpet and can be completely covered by it, the lower carpet remains between the upper carpet and a surface such as the floor, thus keeping it clean and tidy. Therefore, the lower carpet does not require frequent cleaning. When the carpet needs cleaning, only the upper carpet, which is in frequent contact with the carpet, needs to be cleaned. In this case, the upper carpet can be directly separated from the lower carpet and cleaned to keep the carpet clean and tidy. Attached Figure Description

[0039] Reference Figures 1 to 5 This utility model provides a modular carpet, including an upper carpet body 1 and a lower carpet body 2. The upper carpet body 1 includes a first anti-slip layer 11, and the top of the lower carpet body 2 is provided with a first flexible fabric layer 21. The size of the lower carpet body 2 is smaller than the size of the upper carpet body 1, so that the lower carpet body 2 can be completely covered by the upper carpet body 1. The upper carpet body 1 covers the first flexible fabric layer 21 of the lower carpet body 2 with its first anti-slip layer 11, so that the upper carpet body 1 and the lower carpet body 2 can be relatively stationary through static friction, forming a detachable combination. It is understood that the first anti-slip layer 11 can also be called the first bonding layer, and the first flexible fabric layer 21 can also be called the second bonding layer. In this embodiment, the edge region 11a of the first bonding layer (i.e., the first anti-slip layer 11) extends beyond the second bonding layer (i.e., the first flexible fabric layer 21) to contact the surface 80 of an external object (such as the floor 8) and does not overlap with the second bonding layer (i.e., the first flexible fabric layer 21). The main region 11b of the first bonding layer (i.e., the first anti-slip layer 11) and the second bonding layer (i.e., the first flexible fabric layer 21) are detachably connected by static friction to prevent relative movement when the upper blanket 1 and the lower blanket 2 are connected.

[0040] Specifically, in this utility model, the upper carpet body 1 can completely cover the lower carpet body 2, meaning that when the combined carpet is laid on an object surface 80, such as a floor 8, that is, when the lower carpet body 2 is laid on a horizontal floor 8 and the upper carpet body 1 is laid on the lower carpet body 2, the horizontal projection of the lower carpet body 2 on the floor 8 is completely covered by the horizontal projection of the upper carpet body 1 on the floor 8.

[0041] With the above structural configuration, the combined carpet provided by this utility model uses the first anti-slip layer 11 and the first flexible fabric layer 21 to abut against each other, and the friction between the two allows them to remain relatively stationary; when a person or animal walks on the upper carpet body 1, the force in the horizontal direction is less than the static friction between the two, so that the two can continue to remain relatively stationary and avoid separation. Meanwhile, the detachable combination of the upper and lower carpet bodies allows the upper carpet body 1 and the lower carpet body 2 to be used together or separately as needed. When used together, the thickness of the carpet is effectively increased, resulting in good shock absorption and sound insulation, and a high level of comfort. When used separately in certain scenarios, either the upper carpet body 1 or the lower carpet body 2 can be used individually, thus diversifying the usage scenarios of the modular carpet and enhancing its versatility. In addition, since the lower carpet body 2 is smaller than the upper carpet body 1, it can be completely covered by the upper carpet body 1, keeping the lower carpet body 2 between the upper carpet body 1 and the surface of the object, such as the floor. This allows the lower carpet body 2 to remain clean and tidy, so it does not require frequent cleaning. When the carpet needs cleaning, only the upper carpet body 1, which is in frequent contact, needs to be cleaned. At this time, the upper carpet body 1 can be directly separated from the lower carpet body 2 for cleaning, thus keeping the modular carpet clean and tidy. Since the size of the lower carpet body 2 is smaller than the size of the upper carpet body 1, the portion of the first anti-slip layer 11 of the upper carpet body 1 that does not abut against the first flexible fabric layer 21 can also contact the surface of the object, such as the floor. This can also increase the friction between the upper carpet body 1 and the ground, prevent the upper carpet body 1 from slipping on the floor, and thus improve the carpet's performance.

[0042] Furthermore, since the upper carpet body 1 can be detached from the lower carpet body 2, both can be used independently as carpets, effectively improving the versatility of this carpet. Users can choose according to different usage scenarios. For example, when the space is small, the lower carpet body 2 can be used. Because the top of the lower carpet body 2 has a first flexible fabric layer 21, it has a good appearance, a good feel, a decorative effect, and reduces noise, ensuring a good user experience when used alone. When the floor is slippery, the upper carpet body 1 can be used. Because the bottom of the upper carpet body 1 has a first anti-slip layer 11, it has a good anti-slip effect, ensuring a good user experience when used alone.

[0043] In this embodiment, both the upper blanket body 1 and the lower blanket body 2 are products with a three-dimensional structure and a certain thickness. Specifically, the thickness of the upper blanket body 1 is less than or equal to the thickness of the lower blanket body 2. In this embodiment, to make cleaning the upper blanket body 1 easier, its thickness is less than that of the lower blanket body 2. In this invention, the thickness of the upper blanket body 1 and the lower blanket body 2 refers to the sum of the thicknesses of all layers of the blanket. When the blanket surface has pile, the thickness does not include the pile height. In other embodiments, the pile on the blanket surface can be set higher for a better user experience. The design of the upper blanket body 1 being thinner than the lower blanket body 2 makes it easier to clean, while the thicker lower blanket body 2 increases the overall thickness of the modular carpet, making the modular carpet more comfortable.

[0044] Please refer to it again. Figures 2 to 5 In this embodiment, the upper blanket body 1 further includes a connecting layer 41 and a first layer 12. The connecting layer 41 is disposed on the side of the first anti-slip layer 11 away from the lower blanket body 2, and the first layer 12 is disposed on the side of the connecting layer 41 away from the first anti-slip layer 11.

[0045] In some embodiments, the first anti-slip layer 11 includes a rubber layer or a plastic layer. The rubber layer or plastic layer can be directly attached to the connecting layer 41 by hot pressing, dotting, hot melt adhesive spraying, or hot melt adhesive roller rolling. Alternatively, when the connecting layer 41 is omitted, the rubber layer or plastic layer can be directly attached to the first layer 12 by hot pressing, dotting, hot melt adhesive spraying, or hot melt adhesive roller rolling.

[0046] like Figure 6 As shown, further, in a modified embodiment, the rubber layer or plastic layer may include anti-slip textures or anti-slip bumps 11d, which can be directly attached to the connecting layer 41 by hot pressing, dotting, hot melt adhesive spraying, or hot melt adhesive roller rolling. Alternatively, when the connecting layer 41 is omitted, the anti-slip textures or anti-slip bumps 11d can be directly attached to the first layer 12 by hot pressing, dotting, hot melt adhesive spraying, or hot melt adhesive roller rolling.

[0047] Regarding the formation of multiple anti-slip protrusions 11d, the hot melt adhesive spraying process can be achieved by using a patterned mesh cover in conjunction with spraying equipment, while the hot melt adhesive roller rolling process can be achieved by transferring or printing using a patterned roller.

[0048] like Figure 7As shown, in another modified embodiment, the first anti-slip layer 11 includes a bottom layer 11f and a rubber layer or a plastic layer 11c. The bottom layer 11f can be cotton cloth, but is not limited to cotton cloth. In some embodiments, a layer of cotton cloth (the bottom layer 11f) can be added under or on top of the rubber layer or plastic layer 11c and then hot-pressed to form the first anti-slip layer 11. In other embodiments, the rubber layer or plastic layer can also be directly attached to the bottom layer 11f by hot melt adhesive spraying or hot melt adhesive roller rolling. The bottom layer 11f can be a first fabric layer.

[0049] Specifically, the rubber or plastic layer can be made of thermoplastic vulcanized rubber, also known as thermoplastic rubber, TPR, or TPV. The connecting layer 41 and the first layer 12 are provided on the upper carpet body 1, allowing the upper carpet body 1 to be laid independently on object surfaces for use, and providing a certain degree of shock absorption and sound insulation. Furthermore, using a rubber layer with anti-slip texture improves the anti-slip performance of the upper carpet body 1, and provides a certain degree of elasticity and water resistance, effectively enhancing the anti-slip performance of the first anti-slip layer 11 and expanding its usability. The connecting layer 41 further enhances the comfort of the modular carpet. Adding a layer of cotton cloth under the rubber layer with heat pressing, compared to using the rubber layer directly, directly… If the user doesn't want to use the lower carpet layer, they can directly use the upper carpet layer, which can be laid directly on the ground without moving relative to it. Adding a layer of cotton cloth under the rubber layer with heat pressing further enhances the overall comfort of the carpet compared to using only the rubber layer. The cotton cloth provides better breathability and a softer feel, but its friction is lower than when laid directly on the ground, making it easier to move. However, compared to the lower carpet layer, which also has some friction, the upper carpet layer is less likely to move relative to the lower carpet layer, further improving comfort. In addition to the aforementioned anti-slip structure, the first anti-slip layer can also be hot melt adhesive, applied to the upper structure by spraying or rolling. The upper carpet layer 1 in this invention can be used in areas with high traffic or low requirements for sound insulation and vibration reduction, such as kitchens, living rooms, dining rooms, storage rooms, under furniture, and lobbies of commercial office buildings. Furthermore, the upper carpet layer 1 is thin and soft, can be folded and carried, and can be used temporarily for picnics and camping.

[0050] In this embodiment, the first anti-slip layer 11 further includes a first fabric layer, which is disposed on the side of the rubber layer away from the first layer 12. The first fabric layer is attached to the rubber layer using a hot-pressing process. Specifically, the first fabric layer is cotton cloth, which is directly attached to the rubber layer by hot pressing. Hot-pressing the first fabric layer onto the rubber layer can slow down the aging rate of the rubber layer, thereby increasing its service life. It can also increase the friction of the first anti-slip layer 11, thereby improving its anti-slip capability. This ensures stable anti-slip performance whether used alone or in combination, and enhances the anti-slip performance of the modular carpet. With the addition of the first layer 12, the upper carpet body 1 is softer, offering a better feel and decorative effect, as well as reducing noise. This allows the upper carpet body 1 to provide some shock absorption and sound insulation when used alone, resulting in higher comfort. The effect is even better when used in combination.

[0051] The lower blanket body 2 also includes a second anti-slip layer 22, which is disposed on the side of the first flexible fabric layer 21 away from the upper blanket body 1. The second anti-slip layer 22 is used to abut against the surface of the object. The provision of the second anti-slip layer 22 ensures that the lower blanket body 2 has good anti-slip performance whether used alone or in combination, thereby improving the user experience of the product.

[0052] Specifically, the lower carpet body 2 further includes a second layer 42, which is disposed between the first flexible fabric layer 21 and the second anti-slip layer 22. Specifically, the thickness of the second layer 42 is greater than the thickness of the connecting layer 41. The inclusion of the second layer 42 increases the thickness of the lower carpet body 2, improving product comfort and user experience. Furthermore, the greater thickness of the second layer 42 results in a thicker overall composite carpet, enhancing shock absorption and sound insulation, thereby improving product comfort. The lower carpet body 2 of this invention can be used in areas with low foot traffic or high requirements for shock absorption and sound insulation, such as attics, bedroom floors, and staircases, to maintain a quiet and comfortable environment.

[0053] Specifically, in some embodiments, the connecting layer 41 can be omitted, meaning the upper blanket body 1 can be a double-layer structure consisting of a first bonding layer 11 and a first layer 12. The first layer 12 is located on the outermost part of the upper part of the upper blanket body 1 and is used for contact with the user. The material of the first layer 12 includes cotton, polyester, nylon, and / or modal, and the material of the second layer 42 includes wool, polyester, acrylic, chemical fiber, and / or polypropylene.

[0054] Please see Figure 8In one embodiment of this invention, the second anti-slip layer 22 comprises silicone, which is attached to the surface of the second layer 42 away from the first flexible fabric layer 21 using a dot-molding process. Dot-molding the silicone onto the second layer 42 not only increases the product's friction and improves its anti-slip ability, but also makes the product more aesthetically pleasing. Furthermore, silicone is non-toxic, odorless, and more environmentally friendly, and has a soft touch, providing a better user experience. In other embodiments, plastic can be used instead of silicone to reduce costs.

[0055] Please see Figure 9 In another embodiment of this utility model, the second anti-slip layer 22 includes a second fabric layer 222 and a hot melt adhesive layer 221. The second fabric layer 222 is laminated to the side of the second layer 42 away from the first flexible fabric layer 21, and the hot melt adhesive layer 221 is coated on the surface of the second fabric layer 222 away from the second layer 42. The coating method can be spraying the hot melt adhesive onto the second fabric layer 222, scraping the hot melt adhesive onto the second fabric layer 222 with a scraper, brushing the hot melt adhesive onto a roller, or dipping, brushing, etc., as long as the hot melt adhesive can be coated onto the second fabric layer 222. Coating the second fabric layer 222 with hot melt adhesive is not only non-toxic and environmentally friendly, but also has a good feel and a certain degree of adhesion, giving the carpet body 2 a certain viscosity with the object surface such as a floor, thus allowing the carpet body 2 to adhere to the object surface in an adhesive manner, improving the carpet's anti-slip ability.

[0056] Specifically, please refer to Figure 10 The second fabric layer 222 includes a plurality of first threads 7 and a plurality of second threads 8, which are arranged in a crisscross pattern to form the second fabric layer 222. Hot melt adhesive is attached to the first threads 7 and the second threads 8, and some of the hot melt adhesive also enters the first threads 7 and the second threads 8. Since the first threads 7 and the second threads 8 are woven to form the second fabric layer 222, weaving holes 9 are formed between them. When hot melt adhesive is applied to the second fabric layer 222, the weaving holes 9 are not blocked, thereby improving the anti-slip performance while also making the carpet body 2 breathable, effectively enhancing the carpet's usability.

[0057] Both the first weave thread 7 and the second weave thread 8 are cotton threads, which have good air permeability, moisture absorption, and more stable adhesion to thermoplastic rubber. Of course, the first and second weave threads can also be hemp fiber threads, silk threads, synthetic fiber threads, etc. In other embodiments, the first fabric layer can be obtained using the same method as the second fabric layer 222.

[0058] In this embodiment, both the connecting layer 41 and the second layer 42 are needle-punched nonwoven fabrics; both the first flexible fabric layer 21 and the first layer 12 are made of polyester. Specifically, the first flexible fabric layer 21 and the first layer 12 are cord pile layers woven from polyester. Cord pile has a full and soft pile surface, good drape, good water absorption, antistatic properties, and antibacterial properties, which effectively improve the carpet's performance.

[0059] In other embodiments, the first flexible fabric layer 21 and the first layer 12 can be made of different materials, such as corduroy, wool, nylon, polyester, or cotton. To provide waterproofing, they can also be hydrophobic layers, or a mixture of flexible and hydrophobic materials woven in a certain proportion; this application does not impose any limitations. In other embodiments, the connecting layer 41 and the second layer 42 can also be made of flexible materials such as chemical fibers, coconut fiber, or pure cotton, as long as they can achieve cushioning, shock absorption, noise reduction, and improved comfort.

[0060] Please see Figure 3 In this embodiment, the upper carpet body 1 further includes a first knitted edge binding 51, which is disposed along the side of the upper carpet body 1 and covers the edges of the first layer 12, the connecting layer 41, and the first anti-slip layer 11. In other embodiments, the first knitted edge binding 51 may only cover the edges of the first layer 12 and the connecting layer 41. Through the above structural design, the abrasion resistance of the side of the upper carpet body 1 is improved while retaining the original texture of the upper carpet body 1, making the upper carpet body 1 less prone to edge detachment and further extending the service life of the carpet 1.

[0061] Please see Figure 4 The lower blanket body 2 also includes a second knitted edge 52, which is arranged along the side of the lower blanket body 2 and covers the edges of the first flexible fabric layer 21, the second layer 42, and the second anti-slip layer 22. This structural design improves the abrasion resistance of the lower blanket body 2's sides while preserving its original texture, making it less prone to edge fraying and further extending the carpet's lifespan.

[0062] In embodiments of this utility model, the upper blanket body 1 and the lower blanket body 2 can be circles, rectangles, or other polygons, as well as combinations of different polygons, such as... Figure 11The diagram illustrates a circular modular carpet. To improve the comfort of the modular carpet and facilitate the calculation and cutting of carpet dimensions during production, this invention limits the area dimensions of the upper carpet body 1 and the lower carpet body 2. Specifically, the percentage of the area of ​​the lower carpet body 2 to the area of ​​the upper carpet body 1 ranges from 50% to 95%. More specifically, the percentage of the area of ​​the lower carpet body 2 to the area of ​​the upper carpet body 1 can be 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, or 95%, and other values ​​are also acceptable as long as they fall within the aforementioned range.

[0063] To further enhance the comfort of using the modular carpet, it is essential to maximize the overlap area between the upper and lower carpet bodies (1) during use and to avoid issues such as edge curling, displacement, and installation difficulties at the edges of the upper carpet body 1. Therefore, in this invention, the percentage of the area of ​​the lower carpet body 2 relative to the area of ​​the upper carpet body 1 is limited to 55%-90%, preferably 55%-80%. In this embodiment, the specific shapes of the upper and lower carpet bodies 1 and 2 are not limited; their projections on the floor can be rectangular, circular, or other shapes, as long as the percentage of the area of ​​the lower carpet body 2 relative to the area of ​​the upper carpet body 1 is within the aforementioned range.

[0064] In this embodiment, both the upper blanket body 1 and the lower blanket body 2 are rectangular in shape, having a long side, a short side, and a certain height. Therefore, the upper blanket body 1 and the lower blanket body 2 have length, width, and thickness. To facilitate production calculations and cutting, this embodiment of the invention limits the ratio of the length and width of the upper blanket body 1 and the lower blanket body 2. The ratio of the length of the lower blanket body 2 to the length of the upper blanket body 1 is limited to 60%-100%. Specifically, the ratio of the length of the lower blanket body 2 to the length of the upper blanket body 1 can be 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, or 100%, and can also be other values, as long as they are within the aforementioned range. To further enhance the comfort and broaden the application scenarios of modular carpets, and to ensure that at least a portion of the long or wide side of the upper carpet 1 can be laid on a surface such as a substrate after assembly, thus avoiding problems such as edge curling, displacement, and laying difficulties at the edges of the upper carpet 1, the length ratio of the lower carpet 2 to the upper carpet 1 is limited to 75%-95%, preferably 80%-95%. Simultaneously, the width ratio of the lower carpet 2 to the upper carpet 1 is limited to 100%-55%. This width ratio can be 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, or 100%, or any other value within the aforementioned range. Preferably, the width ratio of the lower carpet 2 to the upper carpet 1 is limited to 95%-60%. Specifically, in this embodiment of the invention, the width ratio of the lower carpet body 2 to the upper carpet body 1 is limited to between 60% and 90%, which can make the combination carpet more comfortable and less problematic during use.

[0065] Please see Figure 12 In this embodiment, the surface of the first anti-slip layer 11 facing the first flexible fabric layer 21 is further provided with alignment marks 13. The alignment marks 13 are used to align the long side, short side, or corner of the lower carpet body 2, so that when the upper carpet body 1 is laid on top of the lower carpet body 2, the lower carpet body 2 is located below a predetermined position of the upper carpet body 1. In this embodiment, the alignment marks 13 adopt a circular pattern. When laying the modular carpet, the corner of the lower carpet body 2 is aligned with the alignment marks 13, and then the modular carpet is laid on the floor, thus placing the lower carpet body 2 at the predetermined position of the upper carpet body 1. It can be understood that the predetermined position is the area defined by the alignment marks 13. Setting the alignment marks 13 makes it easier to align the lower carpet body 2 and the upper carpet body 1 during laying, thereby making modular laying more convenient.

[0066] Please see Figure 13In other embodiments, the modular carpet further includes adhesive tape 14, which is applied to the four corners of the first anti-slip layer 11 in four directions (taking a cuboid shape as an example) to adhere the upper carpet body 1 to the surface of the object. The adhesive tape 14 can be used separately or directly attached to the first anti-slip layer 11; it can be removed during use. This application does not impose any limitations. The adhesive tape 14 allows the upper carpet body 1 to adhere more firmly to the surface of the object, preventing relative sliding between the upper carpet body 1 and the lower carpet body 2, and further ensuring the stability of the modular carpet laid on the surface of the object, thus improving its anti-slip capability.

[0067] Reference Figures 14-16 As shown, Embodiment Seven of this application provides a modular carpet, which includes an upper carpet body 1 and a lower carpet body 2. The upper carpet body 1 includes a first bonding layer 11. The lower carpet body 2 is laid between the upper carpet body 1 and an object surface, and includes a second bonding layer 21. The edge region 11a of the first bonding layer 11 extends beyond the second bonding layer 21 to contact the object surface 80 (such as the surface of a floor 8) and does not overlap with the second bonding layer 21. That is, the upper carpet body 1 covers the lower carpet body 2 and has a larger area than the lower carpet body 2. The main region 11b of the first bonding layer 11 and the second bonding layer 21 are detachably connected by a mechanical interlocking structure to prevent relative movement when the upper carpet body 1 and the lower carpet body 2 are connected. It can be understood that the mechanical interlocking structure between the first bonding layer 11 and the second bonding layer 21 can generate static friction between the first bonding layer 11 and the second bonding layer 21 to prevent relative movement when external force is applied to the upper carpet body 1 or the lower carpet body 2.

[0068] Static friction refers to the force that resists the relative motion tendency of an object when it has a tendency to move relative to another object's surface but does not actually move relative to it. In other words, there is a tendency for relative motion between the main area of ​​the first bonding layer 11 and the second bonding layer 21, but relative motion will not actually occur. Thus, the upper blanket 1 is placed on the lower blanket 2, and its weight is applied to the lower blanket 2. Combined with the binding force of the mechanical interlocking structure, static friction is generated between the upper blanket 1 and the lower blanket 2, which can create a detachable connection. That is to say, compared with the prior art, by using the first bonding layer 11 and the second bonding layer 21, the mechanical interlocking structure between them can be used to keep them relatively stationary. When a person or animal walks on the carpet, the force in the horizontal direction is less than the static friction between them (including the weight of the upper blanket 1 and the binding force of the mechanical interlocking structure), so that they can continue to remain relatively stationary and avoid separation.

[0069] Meanwhile, the detachable combination of the upper and lower carpets allows them to be used individually or in combination as needed. When used in combination, the carpet thickness is effectively increased, resulting in excellent shock absorption and sound insulation, and a higher level of comfort. When used individually in certain scenarios, either the upper or lower carpet can be used separately, thus diversifying the use cases of the modular carpet and enhancing its versatility. Furthermore, because the lower carpet is smaller than the upper carpet, it can be completely covered by it, remaining between the upper carpet and surfaces such as the floor. This keeps the lower carpet clean and tidy, reducing the need for frequent cleaning. When cleaning is required, only the frequently touched upper carpet needs to be cleaned. The upper carpet can then be directly separated from the lower carpet for cleaning, maintaining the carpet's cleanliness.

[0070] Further, please refer to Figure 17 and Figure 18 The upper carpet body 1 also includes a first layer 12 located on the side of the first bonding layer 11 away from the second bonding layer 21, so that the upper carpet body 1 can also be laid on the surface of an object for use, and has a certain shock absorption and sound insulation effect; the lower carpet body 2 also includes a second layer 42 located on the side of the second bonding layer 21 away from the first bonding layer 11. The setting of the second layer 42 can increase the thickness of the lower carpet body 2, improve the comfort and user experience of the product, and the thickness of the second layer 42 is set to be thicker, making the overall thickness of the combined carpet thicker, improving the shock absorption and sound insulation effect, thereby improving the comfort of the product. The lower carpet body 2 can be used alone in places with low traffic or high requirements for shock absorption and sound insulation, such as attics, bedroom floors, stairs, etc., to keep the environment quiet and comfortable.

[0071] Furthermore, the first layer 12 is located on the outermost part of the upper blanket body 1 and is used to contact the user. The material of the first layer 12 includes cotton, polyester, polypropylene, wool, nylon and / or modal, which are more comfortable and provide a better user experience.

[0072] Furthermore, the upper carpet body 1 also includes a connecting layer 41 located between the first layer 12 and the first bonding layer 11, which can further enhance the comfort of the modular carpet after the connecting layer 41 is provided.

[0073] Furthermore, the material of the second layer 42 includes wool, polyester, acrylic, non-woven fabric, sponge, chemical fiber and / or polypropylene. The thickness of the second layer 42 is thicker than that of the connecting layer 41. Therefore, the thickness of the second layer 42 is set to be thicker, making the overall thickness of the modular carpet thicker, improving the shock absorption and sound insulation effect, thereby enhancing the comfort of the product.

[0074] Furthermore, such as Figures 16 to 18 As shown, the lower blanket body 2 also includes an anti-slip bottom layer 22 disposed on the second layer 42 away from the second bonding layer 21. The anti-slip bottom layer 22 can be attached to the second layer 42 by hot melt adhesive spraying or hot melt adhesive roller rolling.

[0075] In this embodiment, the anti-slip bottom layer 22 includes a bottom layer 2031 connected to the second layer 42 and a plurality of anti-slip protrusions 2032 disposed on the side of the bottom layer 2031 away from the second layer 42. The anti-slip protrusions 2032 are preferably arranged to cover the bottom layer 2031 of the second layer 42. When laid on the surface 80 of an object, they prevent the movement of the combined carpet, increase the stability of the carpet laying, and also increase the safety of the user. Of course, in addition to setting anti-slip protrusions 2032, suction cups can also be used, but it is preferred to use multiple anti-slip protrusions 2032.

[0076] Furthermore, the anti-slip protrusions 2032 are made of plastic or rubber, or materials with a certain degree of friction.

[0077] The plurality of anti-slip protrusions 2032 can be attached to the bottom layer 2031 by hot pressing, dotting, hot melt adhesive spraying, or hot melt adhesive roller rolling. In some embodiments, the bottom layer 2031 can be omitted, and the plurality of anti-slip protrusions 2032 can be directly attached to the second layer 42 by hot pressing, dotting, hot melt adhesive spraying, or hot melt adhesive roller rolling.

[0078] Regarding the formation of multiple anti-slip protrusions 2032, the hot melt adhesive spraying process can be achieved by using a patterned mesh cover in conjunction with spraying equipment, while the hot melt adhesive roller rolling process can be achieved by transferring or printing on a patterned roller.

[0079] Furthermore, the upper blanket body 1 also includes a first knitted edging 104 located on the side and top edges of the first layer 12 and the side and bottom edges of the first bonding layer 11. The first knitted edging 104 includes a first sewing thread layer 105 sewn to the top edge of the first layer 12 and the bottom edge of the first bonding layer 11 and surrounding the side edges of the first layer 12 and the first bonding layer 11. By binding the edges of the first layer 12 and the first bonding layer 11, the upper blanket body appears neater and more beautiful. The first sewing thread layer 105 is used to fix it firmly, and it is not easy to break or separate during machine washing. Even if it is damaged, it is easy to repair. If the two are directly connected with adhesive, the two layers can be clearly seen at the edges, which is not beautiful. Moreover, the two are easy to separate after machine washing, resulting in a poor user experience.

[0080] Furthermore, the lower blanket body 2 also includes a second knitted edging 52 located on the side and top edges of the second bonding layer 21 and the side and bottom edges of the bottom layer 2031. The second knitted edging 52 includes a second sewing thread layer 521 sewn to the top edge of the second bonding layer 21 and the bottom edge of the bottom layer 2031 and surrounding the side edges of the second bonding layer 21, the second layer 42, and the bottom layer 2031. By binding the edges of the second layer 42 and the second bonding layer, the overall appearance of the lower blanket body becomes neater and more beautiful. The second sewing thread layer 521 is used to fix it firmly, and it is not easy to break or separate during machine washing. Even if it is damaged, it is easy to repair. If the two are directly connected with adhesive, the two layers can be clearly seen at the edges, which is not beautiful. Moreover, the two are easy to separate after machine washing, resulting in a poor user experience.

[0081] Furthermore, the surface area of ​​the upper rug 1 is larger than that of the lower rug 2. The percentage of the surface area of ​​the lower rug 2 to the surface area of ​​the upper rug 1 is between 50% and 99.7%, preferably between 55% and 90%. This creates a buffer zone from the edge of the upper rug 1 towards the combined area of ​​the upper rug 1 and the lower rug 2. The thinner upper rug 1 provides better connection to the floor, reducing the risk of tripping over excessively high rugs in homes with children. The combined area of ​​the upper and lower rugs offers greater comfort, thus improving the overall user experience. In this embodiment, the specific shapes of the upper rug 1 and the lower rug 2 are not limited; their projections on the floor can be rectangular, circular, or other shapes, as long as the percentage of the area of ​​the lower rug 2 to the area of ​​the upper rug 1 is within the aforementioned range.

[0082] Furthermore, such as Figure 16 As shown, the edge region 11a of the upper blanket 1 corresponds to the edge region 11a of the first bonding layer 11 and is annular. The annular edge region 11a of the upper blanket 1 is located outside the annular edge region of the lower blanket 2 and is used to contact the object surface 80. The width A of the portion of the annular edge region 11a of the upper blanket 1 that contacts the object surface 80 is in the range of 0.5cm to 50cm. The annular edge region 11a of the upper blanket 1 refers to the area of ​​the upper blanket 1 that extends beyond the lower blanket 2 and can directly contact the object surface 80. The width A of the annular edge region 11a should be in the range of 0.5cm-50cm, such as 2cm-20cm, or 2cm, 5cm, 8cm, 10cm, 12cm, 15cm, etc., and its value can also be other values, as long as it is within the aforementioned range. In this way, the buffering from the edge of the upper blanket 1 to the combined area of ​​the upper blanket 1 and the lower blanket 2 is better, improving the user's comfort. In one embodiment, the width A is in the range of 2.5cm to 3.5cm.

[0083] Furthermore, one of the first bonding layer 11 and the second bonding layer 21 is a hook-and-loop layer 61, and the other of the first bonding layer 11 and the second bonding layer 21 is a terry loop layer 62, as shown below. Figure 18 , Figures 19 to 22 As shown, the hook-shaped first fabric fibers 63 of the hook-face layer 61 can extend into and hook the multiple second fabric fibers 64 of the loop layer 62, so that the first bonding layer 11 and the second bonding layer 21 are bonded together, thus forming static friction. However, the first bonding layer 11 and the second bonding layer 21 are different from the hook-face layer 61 or loop layer 62 which are directly set by hook and loop fasteners. The loop layer 62 is a soft layer, and the side that is bonded to the hook-face layer 61 is a velvety surface. The hook-face layer 61 is a hard layer, and the side that is opposite to the loop layer 62 has burrs, that is, hooks. In this way, the first bonding layer 11 and the second bonding layer 21 are very easy to bond together and form static friction. This setting uses the inherent characteristics of the materials themselves, resulting in a longer service life.

[0084] Furthermore, such as Figures 19-20 As shown, at least one of the hook-face layer 61 and the terry layer 62 is a weft-knitted fabric layer. When both the hook-face layer 61 and the terry layer 62 are plain knitted weft-knitted fabric layers, the first width of each weft-knitted unit 61a of the hook-face layer 61 is greater than the second width of each weft-knitted unit 62a of the terry layer 62, resulting in more stable static friction. It can be understood that in this embodiment, both the hook-face layer 61 and the terry layer 62 are plain knitted weft-knitted fabric layers. Figure 19 The left side is an actual photograph of the loop layer 62 of one embodiment, and the right side is a schematic diagram of the fabric structure of a part of the actual photograph, wherein each weft knitting unit 62a is the smallest repeating unit of the loop layer 62 fabric. Figure 20 The left side is an actual photograph of the hook-face layer 61 of one embodiment, and the right side is a schematic diagram of the fabric structure of a part of the actual photograph, wherein each weft knitting unit 61a is the smallest repeating unit of the hook-face layer 61 fabric.

[0085] Furthermore, for each weft knitting unit 61a of the hook-and-face layer 61, the first width W1 can be in the range of 700um to 1500um, preferably 800um, 850um, 900um, 910um, 950um, or 1000um, and its value can also be other values, as long as it is within the aforementioned range; the second width W2 is in the range of 500um to 1300um, preferably 600um, 700um, 750um, 800um, 830um, 850um, or 900um, and its value can also be other values, as long as it is within the aforementioned range; hook-and-face layer The first height H1 of each weft knitting unit 61a of layer 61 is greater than the second height H2 of each weft knitting unit 62a of layer 62; the first height H1 is in the range of 400um to 1000um, preferably 600um, 700um, 710um, 750um, or 800um, and its value can also be other values ​​as long as it is within the aforementioned range; the second height H2 can be in the range of 300um to 900um, preferably 500um, 550um, 590um, 600um, 650um, or 700um, and its value can also be other values ​​as long as it is within the aforementioned range.

[0086] The warp density (i.e., longitudinal direction) of the hook layer 61 is in the range of 6 coils / cm to 22 coils / cm, preferably 10 coils / cm, 12 coils / cm, 14 coils / cm, 16 coils / cm, or 18 coils / cm. Other values ​​are also acceptable as long as they fall within the aforementioned range. The weft density (i.e., transverse direction) of the hook layer 61 is in the range of 5 coils / cm to 18 coils / cm, preferably 7 coils / cm, 9 coils / cm, 11 coils / cm, or 13 coils / cm. Other values ​​are also acceptable as long as they fall within the aforementioned range. The warp density of the terry loop layer 62 is in the range of 6 coils / cm to 22 coils / cm, preferably 92 coils / cm, 12 coils / cm, 15 coils / cm, 17 coils / cm, or 19 coils / cm. Other values ​​are also acceptable as long as they are within the aforementioned range. The weft density of the terry loop layer 62 is in the range of 5 coils / cm to 18 coils / cm, preferably 8 coils / cm, 10 coils / cm, 12 coils / cm, 14 coils / cm, or 16 coils / cm. Other values ​​are also acceptable as long as they are within the aforementioned range.

[0087] Furthermore, in this embodiment, as Figure 21 and 22As shown, the curvature of most of the first fabric fibers 63 is greater than that of most of the second fabric fibers 64, such that the average curvature of the first fabric fibers 63 can be greater than the average curvature of the second fabric fibers 64. In other words, the curvature of the first fabric fibers 63 is greater than that of the second fabric fibers 64. The diameter of the first fabric fibers 63 is greater than or equal to the diameter of the second fabric fibers 64. The diameters of the first fabric fibers 63 and the second fabric fibers 64 are in the range of 10 μm to 50 μm, preferably 15 μm, 16 μm, 17 μm, 18 μm, 20 μm, 22 μm, 25 μm, and 30 μm. The hardness of the first fabric fibers 63 is greater than that of the second fabric fibers 64.

[0088] Furthermore, both the first fabric fiber 63 and the second fabric fiber 64 comprise polyester fibers.

[0089] Furthermore, the material of the terry layer 62 may include terry yarn and be brushed.

[0090] It is understood that in the composite carpet of the above embodiment, one of the first bonding layer 11 and the second bonding layer 21 is a hook-face layer 61, and the other of the first bonding layer 11 and the second bonding layer 21 is a loop layer 62. Multiple hook-shaped first fabric fibers 63 of the hook-face layer 61 extend into and hook onto multiple second fabric fibers 64 of the loop layer 62, thus bonding the first bonding layer 11 and the second bonding layer 21 together. Through the setting of the materials and fabric fiber parameters of the first bonding layer 11 and the second bonding layer 21, the first bonding layer 11 and the second bonding layer 21 are bonded together. Layer 21 is made of material with a hook-and-loop layer 61 or a loop layer 62. This is different from some existing hook and loop fasteners with poor tactile feel. The loop layer 62 is a soft layer with a velvety side that is attached to the hook-and-loop layer 61. The hook-and-loop layer 61 is a hard layer with burrs (hook-like) on the side opposite to the loop layer 62. Because the fiber size is small and the range is appropriate, it is less likely to cause the discomfort of ordinary hook and loop fasteners. Moreover, the first bonding layer 11 and the second bonding layer 21 can be tightly bonded, mainly by using the physical properties between the materials themselves, resulting in a longer service life.

[0091] In summary, compared to existing technologies, the modular carpet provided in Embodiment 7 of this utility model, by employing the first bonding layer 11 and the second bonding layer 21 in contact, utilizes the mechanical interlocking structure between them to maintain relative stillness. When a person or animal walks on the carpet, the horizontal force is less than the mechanical interlocking force between them, allowing them to continue to remain relatively still and preventing separation. Furthermore, the detachable combination of the two layers allows the upper and lower carpet bodies to be used in combination or individually as needed. When used in combination, the carpet thickness is effectively increased, resulting in a carpet with good shock absorption and sound insulation, and higher comfort. When individual use is required in certain scenarios, either the upper or lower carpet body can be used separately, thus diversifying the application scenarios of the modular carpet and enhancing its versatility. Furthermore, since the lower carpet is smaller than the upper carpet and can be completely covered by it, the lower carpet remains between the upper carpet and a surface such as the floor, thus keeping it clean and tidy. Therefore, the lower carpet does not require frequent cleaning. When the carpet needs cleaning, only the upper carpet, which is in frequent contact with the carpet, needs to be cleaned. In this case, the upper carpet can be directly separated from the lower carpet and cleaned to keep the carpet clean and tidy.

[0092] It is understood that in Embodiment Seven, the upper blanket body 1 is disposed on the lower blanket body 2, and most of its weight is applied to the lower blanket body 2. However, the connection between the two is mainly through the binding force of the mechanical interlocking structure. In this embodiment, the binding force of the mechanical interlocking structure can be greater than the weight of the lower blanket body 2. Therefore, when the upper blanket body 1 and the lower blanket body 2 are connected as one unit, the lower blanket body 2 will not detach from the upper blanket body 1 when only the upper blanket body 1 is removed. Furthermore, the binding force of the mechanical interlocking structure can also be greater than the weight of the upper blanket body 1. Therefore, when the upper blanket body 1 and the lower blanket body 2 are connected as one unit, the upper blanket body 1 will not detach from the lower blanket body 2 when only the lower blanket body 2 is removed. However, in Embodiment One, when only the upper blanket body 1 is picked up, the lower blanket body 2 will separate from the lower blanket body 2 due to gravity.

[0093] The above description provides one or more embodiments in conjunction with specific content, but it is not intended that the specific implementation of this utility model is limited to these descriptions. Any methods or structures that are similar to or identical to those of this utility model, or any technical deductions or substitutions made based on the concept of this utility model, should be considered within the scope of protection of this utility model.
