[0033] Hereinafter, the technical solutions of the present invention will be further described in conjunction with embodiments and drawings.

[0034] Please refer to Figures 1 to 3 , an anti-slip carpet 1 is disclosed in an embodiment of the present invention, which can be applied to a staircase 2. The staircase 2 includes an adjacent tread 201 and riser 202. The anti-slip carpet 1 includes a carpet body 10 and a buckle assembly 20. The carpet body 10 is used to cover the tread 201 and riser 202, and the carpet body 10 is provided with a clamping portion 11. The buckle assembly 20 includes a fixing body 21 and a fastening portion 22. The fixing body 21 is used to connect to the tread 201 and / or riser 202 of the staircase, and the fastening portion 22 is arranged on the fixing body 21. The fastening portion 22 is used to be snap-connected to the clamping portion 11 so that the carpet body 10 is detachably connected to the buckle assembly 20.

[0035] Through the snap connection between the clamping portion 11 of the carpet body 10 and the fastening portion 22 of the buckle assembly 20, the detachable connection between the anti-slip carpet 1 and the staircase 2 is realized. The carpet body 10 can be well fixed on the staircase 2, effectively preventing the carpet 1 from shifting due to pedestrian trampling, and also avoiding the risk of the carpet 1 arching due to its displacement and not fitting the surface of the staircase 2, thus causing pedestrians to trip. It plays a good anti-slip role and is beneficial to improving the use safety of the carpet 1.

[0036] It can be understood that the foregoing fixed body for connecting to the pedal and / or the riser means that when the fixed body is connected to the staircase, the fixed body 21 can be connected to the pedal 201 of the staircase, or can also be connected to the riser 202 of the staircase, or can further be connected to both the pedal 201 and the riser 202 simultaneously. Regardless of the connection method adopted, the fixed body 21 can be connected to the step 200 of the staircase 2, so that the carpet body 10 can be fixed on the staircase 2.

[0037] Optionally, considering that the engaging portion 11 and the carpet body 10 are often made of different materials. For example, the material of the carpet body 10 includes but is not limited to fiber fabrics, PVC materials, etc., while the engaging portion 11 can be made of metal or non-metal materials. Based on this, when the engaging portion 11 is provided on the carpet body 10, teeth can be provided at one end of the engaging portion 11 connected to the carpet body 10, and the teeth are inserted into the fiber structure of the carpet body 10 to achieve the connection between the engaging portion 11 and the carpet body 10.

[0038] Optionally, the material of the fixed body 21 can be selected as alloys or metal materials such as stainless steel, steel, etc. to have good structural stability. Optionally, the fixed body 21 can be a steel frame. The steel frame structure is beneficial for installation into the step 200, and the inside of the fixed body 21 is also beneficial for forming a corresponding space for the engaging portion 11 to engage.

[0039] In some embodiments, the fixed body 21 includes a first connecting portion 211, a second connecting portion 212, and an end plate 213. The first connecting portion 211 and the second connecting portion 212 are arranged at an angle and are perpendicularly connected to the end plate 213. The first connecting portion 211, the second connecting portion 212, and the end plate 213 enclose an installation space 214. The fastening portion 22 includes a first fastening portion 221. The first fastening portion 221 is connected to the end plate 213 and is located in the installation space 214. Along the extending direction of the riser 202 of the staircase 2, the first fastening portion 221 faces the second connecting portion 212 and is spaced from the second connecting portion 212. The first fastening portion 221 divides the installation space 214 into a first space 2141 and a second space 2142. The space adjacent to the first connecting portion 211 is the first space 2141. The engaging portion 11 at least partially extends into the second space 2142 to engage and connect with the first fastening portion 221.

[0040] An installation space 214 is formed by enclosing with the first connecting portion 211, the second connecting portion 212 and the end plate 213, so that the buckle assembly 20 has a space to accommodate the engaging portion 11. The first buckle portion 221 divides the installation space 214 into a first space 2141 and a second space 2142. In this way, when installing the carpet body 10, the engaging portion 11 can extend into the second space 2142 through the first space 2141 and engage with the first buckle portion 221. The first buckle portion 221 is also spaced from the second connecting portion 212, so that when disassembling the carpet body 10, during the process of separating the engaging portion 11 from the first buckle portion 221, the engaging portion 11 has a certain movement space.

[0041] Specifically, when performing the engaging operation on the engaging portion 11, the side of the engaging portion 11 located in the first space 2141 can be pushed, and the engaging portion 11 can be snapped into the first buckle portion. The engaging portion 11 is set to buckle towards the second space 2142, which can avoid the engaging portion 11 being accidentally touched again in the first space 2141 after the engaging portion 11 is snapped, and improve the efficiency and reliability of the engagement of the engaging portion 11. In addition, through the engagement between the engaging portion 11 and the first buckle portion 221, the engagement connection between the carpet body 10 and the buckle assembly 20 is realized, so as to realize the fixation of the anti-slip carpet 1 on the stairs 2.

[0042] Optionally, the first connecting portion 211 and the second connecting portion 212 can be perpendicularly arranged, and both the first connecting portion 211 and the second connecting portion 212 are plate-like structures. The fixing body 21 can include two end plates 213, and the two end plates 213 are respectively located on both sides of the first connecting portion 211 and the second connecting portion 212. Thus, one end plate 213, the first connecting portion 211, the second connecting portion 212 and the other end plate 213 jointly enclose the above-mentioned installation space 214, and the two end plates 213 can be arranged in parallel. In this way, both ends of the first buckle portion 221 can be respectively connected to the two end plates 213, which is beneficial to improving the connection strength between the first buckle portion 221 and the end plate 213.

[0043] In some embodiments, one end of the first fastening portion 221 facing the engaging portion 11 has a first inclined surface 2210. The engaging portion 11 has a second inclined surface 111 corresponding to the first inclined surface 2210. The second inclined surface 111 is parallel to the first inclined surface 2210. When the engaging portion 11 is engaged with the first fastening portion 221, the second inclined surface 111 is cooperatively connected with the first inclined surface 2210. By the cooperative connection of the engaging portion 11 and the first fastening portion 221 through the inclined surfaces, on the one hand, the angle of the first fastening portion 221 at the engaging position of the engaging portion 11 can be made smaller, increasing the fastening force between the engaging portion 11 and the first fastening portion 221, thereby improving the connection strength between the carpet body 10 and the buckle assembly 20; on the other hand, by providing the inclined surfaces, it can play a guiding role in the process of the engaging portion 11 engaging with or separating from the first fastening portion 221, enabling the engaging portion 11 to be more smoothly engaged with the first fastening portion 221 or removed from the first fastening portion 221.

[0044] In some embodiments, the first fastening portion 221 is arranged along a direction parallel to the vertical plate 202. The first fastening portion 221 further has a first side surface 2211 along a direction parallel to the vertical plate 202 and located in the second space 2142. The included angle between the first side surface 2211 and the first inclined surface 2210 is α, and 30° ≤ α ≤ 50°.

[0045] Optionally, α can be 30°, 35°, 40°, 45°, 50°, etc. By limiting the angle range of the included angle of the first inclined surface 2210, on the one hand, the included angle is not too large, for example, not exceeding 50°, so that the engaging portion 11 and the first fastening portion 221 have a good fastening force and can effectively prevent the engaging portion 11 from loosening from the first fastening portion 221; on the other hand, the included angle is greater than 30°, so that the included angle α is not too small, enabling the first fastening portion 221 to have sufficient thickness, thereby ensuring the strength of the first fastening portion 221 and avoiding the fracture of the first fastening portion 221 during the engaging process.

[0046] In some embodiments, the fastening portion 22 further includes a second fastening portion 222. The second fastening portion 222 is arranged on the second connecting portion 212 and located in the installation space 214. The second fastening portion 222 corresponds to the first fastening portion 221 and is spaced from the first fastening portion 221. When the engaging portion 11 is engaged with the first fastening portion 221, the engaging portion 11 is located in the space between the first fastening portion 221 and the second fastening portion 222. By providing the second fastening portion 222, the second fastening portion 222 can limit the movement of the engaging portion 11 during the process of the engaging portion 11 being engaged with the first fastening portion 221 or removed from the first fastening portion 221.

[0047] Accordingly, one end of the second engaging portion 222 facing the engaging portion 11 has a third inclined surface 2220. The engaging portion 11 has a fourth inclined surface 112 corresponding to the third inclined surface 2220. The fourth inclined surface 112 is parallel to the third inclined surface 2220, and the fourth inclined surface 112 is cooperatively connected to the third inclined surface 2220. In this way, by providing the third inclined surface 2220, it is possible to provide a guiding effect on the action of the engaging portion 11 being inserted or removed, thereby making the operation of installing or disassembling the carpet body 10 smoother. In some examples, the angle formed by the third inclined surface 2220 and the second side surface 2221 of the second engaging portion 222 located in the second space 2142 is β, and 30° ≤ β ≤ 50°. Optionally, β can be 30°, 35°, 40°, 45°, 50°, etc. A smaller β angle (for example, not exceeding 50°) can provide a good guiding effect on the engaging portion 11. However, in order to ensure that the second engaging portion 222 has sufficient strength to avoid breakage, β is set to be not less than 30°. Therefore, limiting β within this angle range can ensure the strength of the second engaging portion 222 and enable the second engaging portion 222 to have a good guiding effect on the engaging portion 11.

[0048] In some embodiments, the buckle assembly 20 further includes a button 23 and a reset member 24. The button 23 and the reset member 24 are located in the second space 2142. One end of the reset member 24 is connected to the second connecting portion 212, and the other end of the reset member 24 is connected to the button 23, and the button 23 is disposed toward the end of the carpet body 10 where the engaging portion 11 is provided. One end of the button 23 facing the reset member 24 abuts against the engaging portion 11, and the button 23 is used to push the engaging portion 11 away from the first engaging portion 221 when a pressing force is applied.

[0049] By providing the button 23, it is possible to release the engagement between the engaging portion 11 and the first engaging portion 221 by pushing the button 23, improving the convenience and efficiency of disassembling the engaging portion 11. The reset member 24 can be a structure such as a spring or a spring piece. The reset member 24 can return to its original shape after being deformed by extrusion, thereby driving the button 23 to return to the position before the pressing force is applied, so as to be used for releasing the engagement of the engaging portion 11 next time.

[0050] Optionally, when the buckle assembly 20 includes the first engaging portion 221 and the second engaging portion 222, the sides of the two located in the second space 2142 are substantially flush. In this way, these two sides form a relatively flat plane, providing a suitable space for the pressing movement of the button 23 and the deformation of the reset member 24, and improving the smoothness of the pressing process of the button 23.

[0051] In addition, the above-mentioned first engaging portion 221 and second engaging portion 222 can both be plate-like structures with an inclined surface on one side, and the engaging portion 11 can be a hook, and the hook is engaged with the inclined surface of the plate-like structure.

[0052] Optionally, the fixed body 21 may further include a third connecting portion 215, and the third connecting portion 215 may specifically be a plate-like structure. The third connecting portion 215 is connected to the second connecting portion 212 and is arranged at an interval from the first connecting portion 211. The third connecting portion 215 and the first fastening portion 221 enclose a second space 2142. In this way, the third connecting portion 215 can separate the second space 2142 from the external space, so that the button 23 performs the pressing and resetting processes within the second space 2142, without being interfered by the outside world and without scratching the carpet body 10, improving the reliability of the working process of the buckle assembly 20.

[0053] In some embodiments, when the fixed body 21 is connected to the staircase 2, the fixed body 21 and the fastening portion 22 extend from one side to the other side of the staircase 2 in the width direction of the staircase 2 (such as the x direction shown). Figure 3 The button 23 and the reset member 24 include a plurality of them, and the plurality of buttons 23 and the plurality of reset members 24 are arranged at intervals along the width direction of the staircase 2. The carpet body 10 is provided with a plurality of engaging portions 11 corresponding to the plurality of buttons.

[0054] By setting the fixed body 21 and the fastening portion 22 to extend along the width direction of the staircase 2, the buckle assembly 20 appears as a long strip-shaped structure in appearance, and the installation space 214 formed by enclosing the fixed body 21 is also a long strip-shaped space extending along the width direction of the staircase. In the long strip-shaped installation space 214, the button 23 and the reset member 24 are arranged at intervals along the width direction of the staircase in the installation space 214. Correspondingly, a plurality of engaging portions 11 on the carpet body 10 are also arranged at intervals along the first direction, and the plurality of engaging portions 11 are respectively snapped into the fastening portion 22 corresponding to the positions where the plurality of buttons 23 are located. In this way, along the width direction of the staircase, the plurality of engaging portions 11 can improve the connection strength between the anti-slip carpet 1 and the staircase 2, make the clamping force distribution between the anti-slip carpet 1 and the staircase 2 more uniform, reduce the clamping force borne by each clamping position on the fastening portion 22, and improve the reliability of the use of the anti-slip carpet 1.

[0055] At the same time, since there are a plurality of engaging portions 11 corresponding to the button 23, each engaging portion 11 can be independently controlled to be engaged or separated from the fastening portion 22, so that the connections between the respective engaging portions 11 and the fastening portion 22 are independent of each other.

[0056] Optionally, along the first direction, the button 23 and the reset member 24 can be arranged at equal intervals, and the distance between two adjacent buttons 23 is greater than or equal to 200 mm, such as 230 mm, 250 mm, 280 mm, etc. In this way, on the premise of ensuring sufficient connection strength between the carpet body 10 and the buckle assembly 20, the number of buttons 23 and reset members 24 can be minimized as much as possible, the structure of the anti-slip carpet 1 can be simplified, and the installation and disassembly efficiency of the anti-slip carpet 1 can be improved.

[0057] Optionally, along the first direction, the two sides of the staircase 2 are wall surfaces 300. The buckle assembly 20 extends along the first direction and the two ends of the buckle assembly 20 are respectively connected to the two wall surfaces 300, so that the end plates 213 at the opposite ends of the fixing body 21 are respectively connected to the wall surfaces 300. When installing the anti-slip carpet 1, the buckle assembly 20 can be pre-embedded at the junction of two adjacent steps 200 first, and the end plate 213 is pre-embedded in the wall surface 300. After the buckle assembly 20 is installed, then cover the carpet body on the surface of the step 200, and at the same time snap the engaging portion 11 into the engaging portion 22 of the buckle assembly 20. In this way, only one buckle assembly 20 needs to be provided at the junction of each step 200, improving the installation efficiency.

[0058] In some embodiments, the fixing body 21 and the engaging portion 22 are integrally formed. The fixing body 21 and the engaging portion 22 can be made of the same material, such as stainless steel, iron or plastic. In this way, on the one hand, the connection strength between the fixing body 21 and the engaging portion 22 can be improved, enhancing the reliability of the use of the anti-slip carpet 1, and on the other hand, the manufacturing efficiency of the buckle assembly 20 is also improved.

[0059] In some embodiments, the fixing body 21 is connected to the tread 201 or the riser 202 of the step 200 by bolts. Since bolt connection has good connection strength, by connecting the fixing body 21 and the step 200 with bolts, not only can a good connection between the buckle assembly 20 and the step 200 be ensured, but also the installation process of the buckle assembly 20 can be simplified, improving the construction efficiency.

[0060] In a second aspect, the present embodiment also provides a staircase 2 with a carpet, including a plurality of continuously arranged steps 200. Each step 200 includes a tread 201 and a riser 202 connected to the tread 201. The staircase 2 further includes the aforementioned anti-slip carpet 1. The buckle assembly 20 is arranged at the junction of the riser 202 and the tread 201. The fixing body 21 is connected to the riser 202 and / or the tread 201. The carpet body 10 covers the tread 201 and the riser 202.

[0061] By arranging the buckle assembly 20 at the connection of the riser 202 and the tread 201, the carpet body 10 can be fixedly connected to the junction of adjacent steps 200, preventing the anti-slip carpet 1 from being deformed, arched or displaced after being stepped on multiple times and being difficult to fit the surface of the steps 200 of the staircase. In this way, after the staircase 2 with the above anti-slip carpet is used for a long time, the anti-slip carpet 1 can still remain in its original position, and the edges at the junction of the riser 202 and the tread 201 of adjacent steps 200 can remain flat and clear, reducing the risk of pedestrians stepping on air and improving the safety of the use of the staircase 2 with a carpet.

[0062] Exemplarily, the fixed body 21 can be connected to the tread 201 of the staircase. For example, when the fixed body 21 includes a first connecting portion 211 and a second connecting portion 212, it can be connected to the tread 201 through the second connecting portion 212 of the fixed body; it can also be connected to the riser 202 of the staircase through the first connecting portion 211; or it can be connected to the tread 201 through the second connecting portion 212 and at the same time be connected to the riser 202 through the first connecting portion 211.

[0063] Optionally, decorative plates 2010 can be laid on the surfaces of the risers 202 and treads 201 of the staircase 2. The decorative plates 2010 are provided with notches at the joints of the risers 202 and treads 201, and the buckle assembly 20 is installed in the notches. In this way, it is possible to minimize the protrusion of the buckle assembly 20 from the plane of the riser 202 or tread 201, maximize the hiding of the buckle assembly 20, reduce the obstruction of the buckle assembly 20 to pedestrians during walking, and at the same time improve the surface flatness of the anti-slip carpet 1, enhancing the practicality and appearance effect.

[0064] In some embodiments, there are multiple buckle assemblies 20, and the multiple buckle assemblies 20 are respectively arranged on multiple steps 200. Taking two adjacent steps 200 as an example, it includes one step 200a and another step 200b adjacent to the one step 200a. The fixed body 21 is connected to the tread 201 of one step 200a and the riser 202 of another step 200b adjacent to the one step 200a. The buckle assembly 20 includes two fastening portions, namely 22a and 22b, and the two fastening portions 22a and 22b are spaced apart and arranged oppositely. Optionally, the two fastening portions 22a and 22b can be symmetrically arranged. One fastening portion 22a corresponds to the tread of one step 200a, and the other fastening portion 22b corresponds to the other step 200b. The staircase 2 includes multiple carpet bodies 10, and each carpet body 10 covers at least part of the tread 201 and / or at least part of the riser 202 of the same step 200. Taking two adjacent carpet bodies 10a and 10b as an example, the engaging portion 11 of one carpet body 10a is engaged with one fastening portion 22a, and the engaging portion 11 of the other carpet body 10b is engaged with the other fastening portion 22b.

[0065] With this solution, for a staircase 2 with multiple steps 200 continuously arranged, it is possible to achieve continuous laying of the anti-slip carpet 1, so that the entire staircase 2 is covered with the anti-slip carpet 1, improving the safety during the use of the staircase 2.

[0066] It can be understood that each of the foregoing carpet bodies 10 covering at least a part of the tread 201 and / or at least a part of the riser 202 of the same step 200 means that: the carpet body 10 can cover only the tread 201 of the step 200, or the carpet body 10 can cover only the riser 202 of the step 200, or the carpet body 10 can cover both the tread 201 and the riser 202 of the step 200. Regardless of which of the above connection methods is adopted between the carpet body 10 and the step 200, the carpet body 10 can be fixed on the surface of the step 200 of the staircase 2 to prevent the carpet 1 from sliding during use.

[0067] The following takes a staircase 2 as an example to illustrate the setting of the anti-slip carpet 1:

[0068] Lay the carpet body 10 of the first anti-slip carpet 1 on the first step 200 at the bottom of the staircase 2. Set the first buckle assembly 20 at the junction of the tread 201 of the first step and the riser 202 of the second step. The engaging portion 11 of the first carpet body 1 is engaged with one of the engaging portions 22 of the first buckle assembly 20. Then, lay the second carpet body 10 on the second step 200. The engaging portion 11 of the carpet body 10 on the side facing the first step is engaged with the other engaging portion 22 of the first buckle assembly 20. Set the second buckle assembly 20 at the junction of the tread 201 of the second step and the riser 202 of the third step. The engaging portion 11 of the second carpet body 10 on the side facing the third step is engaged with one of the engaging portions 22 of the second buckle assembly 20.

[0069] And so on. By setting a plurality of buckle assemblies 20 at the junctions of adjacent steps 200 and laying the carpet bodies 10 on a plurality of steps 200, a plurality of anti-slip carpets 1 can cover a plurality of steps 200 of the staircase 2, thereby achieving the purpose of covering the entire staircase with a carpet. At the same time, the original single-piece staircase carpet is decomposed into a plurality of anti-slip carpets 1, which is convenient for each anti-slip carpet 1 to be disassembled, repaired or cleaned separately, improving the convenience of use and maintenance of the anti-slip carpet 1.

[0070] The above has introduced in detail the anti-slip carpet and the staircase with a carpet disclosed in the embodiments of the present invention.
