Description

Technical Field

[0001] This utility model relates to the field of floor mat structure technology, and in particular to a splicing mat assembly and a fall-proof mat. Background Technology

[0002] As people become more affluent, they are paying more and more attention to body management and safety. In home settings, elastic mats such as yoga mats and protective floor mats provide great convenience and safety for users in scenarios such as yoga, childcare, and aging-friendly renovations.

[0003] For young children who haven't learned to walk or are learning to walk, most families purchase anti-fall mats for them to play and learn to walk. These mats have a certain degree of elasticity to prevent injuries from hard surfaces. However, because these mats need to cover a large area for children, and considering transportation, installation, and storage, existing mats using Velcro or snap fasteners are prone to mechanical fatigue, decreased adhesion, or plastic deformation at the joints after prolonged pressure, bending, or temperature and humidity changes. This can lead to widening gaps at the joints and eventual separation, rendering them ineffective. On the other hand, elderly people are prone to falls and slips during daily activities at home, resulting in injuries such as bone fractures, fractures, and concussions that can cause loss of independence and seriously threaten their health and lives. Flat and stable anti-fall mats can effectively prevent gait instability or loss of balance caused by uneven or slippery surfaces when walking, thus significantly reducing the probability of falls and the risk of injury. Utility Model Content

[0004] The main purpose of this utility model is to provide a splicing pad assembly, which aims to prevent the splicing joints from coming apart and enhance the safety performance of the product.

[0005] To achieve the above objectives, the splicing pad assembly proposed in this utility model includes: Floor mat unit, the floor mat unit having a first connecting portion; and A first connecting block has four second connecting portions. In the thickness direction of the floor mat unit, one second connecting portion is detachably connected to one first connecting portion. The first connecting block can connect four adjacent floor mat units.

[0006] In one embodiment, the splicing pad assembly further includes a second connecting block; The second connecting block has two second connecting portions and is used to connect two adjacent floor mat units.

[0007] In one embodiment, the floor mat unit has an mounting surface and a movable surface that are disposed opposite to each other; The mounting surface has the first connecting portion, and the movable surface is for user contact and use.

[0008] In one embodiment, the first connecting part is a connecting hole, and the second connecting part is a connecting pin; The connecting pin is inserted into the connecting hole and abuts against the wall of the connecting hole for positioning.

[0009] In one embodiment, the floor mat unit has a receiving groove, and the bottom of the receiving groove has the connecting hole; The receiving groove is located at the corner of the floor mat unit, and the groove wall of the receiving groove near the side of the floor mat unit is through-hole; The first connecting block is located within the receiving groove.

[0010] In one embodiment, the splicing pad assembly further includes a pad layer; The pad is disposed in the receiving groove and abuts against the groove wall of the receiving groove, and the pad has a clearance hole facing the connection hole; The first connecting block abuts against the padding layer, and the connecting pin passes through the clearance hole and abuts against the hole wall of the connecting hole.

[0011] In one embodiment, the connecting pin has an expansion portion; The expansion portion is located at the end of the connecting pin and protrudes outwards, and the expansion portion is used to abut against the wall of the connecting hole.

[0012] In one embodiment, the expansion portion has a guide surface; In the direction from one end of the connecting pin to the other end of the connecting pin, the thickness of the expansion gradually increases to form the guide surface on the outer wall surface of the expansion.

[0013] In one embodiment, the connecting pin includes two spaced-apart pins, the sidewalls of which are arranged opposite to each other for abutting against the wall of the connecting hole.

[0014] This utility model also proposes a fall-proof mat, the fall-proof mat comprising: The interlocking mat assembly includes at least four mat units, and the first connecting block connects four adjacent mat units.

[0015] In the technical solution of this utility model, the first connecting block can connect four adjacent floor mat units simultaneously, realizing the connection of multiple floor mat units. When a floor mat unit is subjected to lateral tension, the first connecting block connected to it will transmit and disperse the tension to the other three adjacent floor mat units through the second connecting part, so that the tension is shared by the adjacent floor mat units, thereby suppressing the tendency of a single edge to detach. The multi-directional force balance is used to offset the deformation tension brought by the elasticity of the floor mat unit itself, significantly improving the stability of the splicing node. Furthermore, the connection of the first connecting part and the second connecting part in the thickness direction can convert the lateral shear force on the floor mat unit into friction and mechanical stress between the first connecting part and the second connecting part, thereby providing a lateral limiting capability that traditional lateral splicing does not have. Compared with the structure of traditional anti-fall mats that are directly laterally spliced, the first connecting part can form a lateral limiting with the second connecting part, preventing adjacent floor mat units from detaching and enhancing the safety performance of the product.

[0023] This utility model proposes a splicing pad assembly 100. Figures 1 to 3 This is one embodiment of the present utility model.

[0024] In this embodiment of the utility model, the splicing mat assembly 100 includes a floor mat unit 1 and a first connecting block 2. The floor mat unit 1 has a first connecting part 11, and the first connecting block 2 has four second connecting parts 21. In the thickness direction of the floor mat unit 1, one second connecting part 21 is detachably connected to one first connecting part 11. The first connecting block 2 can connect four adjacent floor mat units 1.

[0025] In the technical solution of this utility model, the first connecting block 2 can connect four adjacent floor mat units 1 at the same time, realizing the connection of multiple floor mat units 1. When a floor mat unit 1 is subjected to lateral tension, the first connecting block 2 connected to it will transmit and disperse the tension to the other three adjacent floor mat units 1 through the second connecting part 21, so that the tension is shared by the adjacent floor mat units 1, thereby suppressing the tendency of a single edge to detach. The multi-directional force balance is used to offset the deformation tension brought by the elasticity of the floor mat unit 1 itself, significantly improving the stability of the splicing node. Furthermore, the connection of the first connecting part 11 and the second connecting part 21 in the thickness direction can convert the lateral shear force on the floor mat unit 1 into the friction force and mechanical stress between the first connecting part 11 and the second connecting part 21, thereby providing a lateral limiting capability that traditional lateral splicing does not have. Compared with the structure of traditional anti-fall mats directly spliced ​​laterally, the first connecting part 11 can form a lateral limiting with the second connecting part 21 to prevent adjacent floor mat units 1 from detaching, enhancing the safety performance of the product.

[0026] During the use of the interlocking mat assembly 100, the items placed on the interlocking mat assembly 100 or the young children and adults playing on the interlocking mat assembly 100 will increase the overall weight of the mat unit 1, making the connection between the first connecting part 11 of the mat unit 1 and the second connecting part 21 of the first connecting block 2 more secure, and making it more difficult to separate the mat units 1.

[0027] In one embodiment, the splicing mat assembly 100 further includes a second connecting block, which has two second connecting portions 21 and is used to connect two adjacent floor mat units 1. The second connecting block is mainly used to connect two floor mat units 1 located at the edge, strengthening the connection between the sides of the two floor mat units 1 located at the edge, avoiding local separation due to lack of effective constraints in the boundary area, and further improving the integrity and reliability of the overall splicing structure.

[0028] In one embodiment, the floor mat unit 1 has an mounting surface 12 and a movable surface 13 arranged opposite to each other. The mounting surface 12 has the first connecting portion 11, and the movable surface 13 is used for user contact. By distinguishing the oppositely arranged mounting surface 12 and movable surface 13, the first connecting portion 11 is concentrated on the mounting surface 12 that contacts the bottom surface, while the movable surface 13, as the side directly contacted by the user, remains flat. The mounting surface 12 is in contact with the ground, and the first connecting portion 11 is not easily disturbed by external collisions. This ensures both the installation space and the reasonable force distribution of the connection structure, and avoids the impact of protruding or exposed connecting parts on the user experience of the movable surface 13. When children or adults crawl, play, or walk on the movable surface 13, they will not bump or trip due to the connection structure. At the same time, the hidden connection design of the mounting surface 12 can reduce dust accumulation and reduce the risk of failure of the connection area due to foreign objects entering, thus taking into account safety, comfort, and structural stability.

[0029] In one embodiment, the first connecting part 11 is a connecting hole 11a, and the second connecting part 21 is a connecting pin 21a. The connecting pin 21a is inserted into the connecting hole 11a and abuts against the wall of the connecting hole 11a for limitation. By using the engagement method of inserting the connecting pin 21a into the connecting hole 11a and abutting against the hole wall for limitation, the detachable connection is transformed into a rigid constraint with a certain friction force. The fitting design of the connecting hole 11a and the connecting pin 21a utilizes the principle of surface contact force in mechanical connections. The static friction force generated by the tight abutment between the connecting pin 21a and the hole wall counteracts the separation tendency caused by the elastic deformation of the floor mat unit 1. Compared with traditional fasteners, Velcro, and other connection methods, this plug-in abutment structure has a more stable connection strength and is less prone to wear and failure due to repeated disassembly. Meanwhile, the abutment between the connecting pin 21a and the hole wall can accommodate the slight elastic deformation of the floor mat unit 1, preserving the cushioning performance of the floor mat unit 1 without affecting the connection stability, thus achieving a functional balance between a stable connection and elastic protection. When the connecting pin 21a abuts against the hole wall, there is a distinct tactile "click" sensation, allowing the user to confirm the secure connection by touch.

[0030] In one embodiment, the floor mat unit 1 has a receiving groove 14, and the bottom of the receiving groove 14 has the connecting hole 11a. The receiving groove 14 is located at the corner of the floor mat unit 1, and the groove wall of the receiving groove 14 near the side of the floor mat unit 1 is through-hole. The first connecting block 2 is located inside the receiving groove 14. This allows the receiving grooves 14 between adjacent floor mat units 1 to communicate with each other and be used together to install the first connecting block 2. The first connecting block 2 is concealed inside the receiving groove 14, avoiding the risk of impact caused by the first connecting block 2 being exposed. Furthermore, the receiving groove 14 can provide a wrapping protection for the first connecting block 2, reducing the impact of external collisions or dust and liquid intrusion on the connection structure.

[0031] In one embodiment, the splicing pad assembly 100 further includes a pad layer 3, which is disposed in the receiving groove 14 and abuts against the groove wall of the receiving groove 14. The pad layer 3 has a clearance hole that is directly opposite the connecting hole 11a. The first connecting block 2 abuts against the pad layer 3, and the connecting pin 21a passes through the clearance hole and abuts against the hole wall of the connecting hole 11a. The padding layer 3 is disposed within the receiving groove 14 and abuts against the groove wall. It also provides a channel for the connecting pin 21a through the clearance hole, thus filling the gap between the receiving groove 14 and the first connecting block 2. Furthermore, since the floor mat unit 1 is mostly made of elastic material, the dimensions of the receiving groove 14 may have slight errors, potentially leading to minor deformation during use. The padding layer 3, through its own elasticity or filling, can eliminate the gap, preventing the first connecting block 2 from shaking within the receiving groove 14, thereby ensuring precise alignment and stable contact between the connecting pin 21a and the connecting hole 11a. Simultaneously, the padding layer 3 can distribute the pressure on the first connecting block 2, reducing deformation or damage to the receiving groove of the floor mat unit 1 caused by localized force concentration, thus balancing connection stability and structural integrity.

[0032] In one embodiment, the connecting pin 21a has an expansion portion 211, which is located at the end of the connecting pin 21a and protrudes outwards. The expansion portion 211 is used to abut against the wall of the connecting hole 11a. The expansion portion 211 enhances the contact and limiting effect between the connecting pin 21a and the connecting hole 11a. As a protruding structure at the end of the pin, the expansion portion 211 forms an interference fit with the hole wall after being inserted into the connecting hole 11a. Utilizing the slight elastic deformation of the floor mat material, the expansion portion 211 can be tightly locked into the connecting hole 11a. Compared to a flat pin, it has greater contact pressure and stronger friction with the hole wall, effectively resisting the separation tension caused by the elasticity of the floor mat unit 1, fundamentally solving the problem of the pin easily coming out of the hole. At the same time, the protruding design of the expansion portion 211 forms an axial limit after the connecting pin 21a is inserted, preventing the connecting pin 21a from shifting due to lateral external forces, further improving the anti-disengagement ability of the connection structure, and does not affect the ease of disassembly of the pin. It can be removed by overcoming the interference fit force with appropriate force.

[0033] In one embodiment, the expansion portion 211 has a guide surface 212. The thickness of the expansion portion 211 gradually increases in the direction from one end of the connecting pin 21a to the other end of the connecting pin 21a, forming the guide surface 212 on the outer wall surface of the expansion portion 211. When the connecting pin 21a is inserted into the connecting hole 11a, the guide surface 212 acts as a guide, converting part of the axial force during insertion into a radial expansion force. This allows the expansion portion 211 to more smoothly open the hole wall of the connecting hole 11a, avoiding insertion difficulties or damage to the hole wall due to the expansion portion 211 directly contacting the hole opening. This reduces the operational difficulty for users during installation and improves the practicality of the product.

[0034] In one embodiment, the connecting pin 21a includes two spaced-apart pins 22, with their oppositely positioned sidewalls abutting against the wall of the connecting hole 11a. The two pins 22 have a certain elastic deformation capability. When inserted into the connecting hole 11a, the pins 22 will slightly converge due to the pressure from the hole wall. After insertion, they will rebound elastically, causing their oppositely positioned sidewalls to tightly abut against the hole wall, forming a bidirectional elastic pressing effect. Compared to a single-piece pin, this generates greater contact pressure and a more uniform contact area, effectively offsetting the radial tension caused by the elastic deformation of the floor mat. Simultaneously, the pins 22 have stronger elastic adaptability, accommodating minor changes in the hole diameter of the connecting hole 11a due to manufacturing errors or deformation during use, avoiding loose connections or insertion difficulties caused by mismatched hole diameters. Furthermore, the spaced-apart structure reduces the overall weight of the connecting pin 21a without affecting the connection strength, balancing practicality and economy.

[0035] It should be noted that the splicing pad assembly 100 may further include a third connecting block, which has three second connecting portions 21 arranged in an "L" shape. In practical applications, when encountering corners, pillars, or other structures, the third connecting block can be used to connect three adjacent floor mat units 1, thereby achieving an effective connection between each floor mat unit 1 at corners, pillars, or other structures. Similar to the irregularly shaped bottom surfaces described above, the shape of the connecting structure used to connect each floor mat unit 1 can be flexibly adjusted; further examples will not be provided here.

[0036] This utility model also proposes an anti-fall mat, which includes the splicing mat assembly 100. The splicing mat assembly 100 includes at least four mat units 1. A first connecting block 2 connects four adjacent mat units 1. Multiple mat units 1 form a complete anti-fall mat under the connection of the first connecting block 2. The anti-fall mat has high lateral tensile strength. When the first connecting block 2 is not separated from each mat unit 1, each mat unit 1 is difficult to separate under lateral tension. The specific structure of the splicing mat assembly 100 is as described in the above embodiments. Since this anti-fall mat adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described in detail here.

[0037] In a preferred embodiment, the floor mat unit 1 is made of medium-to-high density slow-rebound polyurethane foam to provide good cushioning and support; the first connecting block 2, the second connecting block, etc., can be made of materials with good rigidity, such as 3D-printed photosensitive resin, to ensure the strength and durability of the connection structure.

[0038] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
