Description

Technical Field

[0001] This invention relates to the field of demonstration equipment technology, and in particular to a visual demonstration device for the anti-slip performance of footwear. Background Technology

[0002] The anti-slip performance of footwear is closely related to wearing safety. Especially when using footwear products such as slippers, sandals, and lounge shoes, the soles of the shoes are prone to slipping to varying degrees when the user is on wet or slippery surfaces, on different ground materials, on the forefoot, on the heel, or when the body's center of gravity changes.

[0003] In existing technologies, most footwear anti-slip equipment is primarily for testing or experimentation. It typically uses a combination of shoe lasts, ground test boards, loading mechanisms, and pulling mechanisms to test the friction or slippage of individual footwear samples. While this type of equipment can obtain data related to anti-slip performance, its structure and usage are more geared towards experimental testing, making it difficult for observers to visually discern differences in the timing and degree of slippage between different types of footwear, on different surfaces, or under different wet / slip conditions.

[0004] Meanwhile, existing footwear anti-slip demonstration or testing structures, when simulating the human foot's landing posture, mostly use fixed angles, fixed shoe lasts, or simple tilted supports. These methods typically only demonstrate the slippage results in a static posture and are insufficient to simulate the changes in the foot's position (e.g., forefoot, heel) during walking. For footwear anti-slip training, users need to observe how the footwear gradually slips during posture changes, a process that current equipment struggles to visually represent. Summary of the Invention

[0005] Therefore, there is a need to provide a visual demonstration device for the anti-slip performance of footwear to solve the problem that existing anti-slip equipment is difficult to intuitively demonstrate the slippage process and slippage differences of different types of footwear under different conditions due to design flaws.

[0006] To achieve the above objectives, the inventors provide a visual demonstration device for the anti-slip performance of footwear, comprising:

[0007] At least two parallel presentation channels;

[0008] A ground simulation board is installed in each of the aforementioned demonstration channels to simulate the ground.

[0009] Simulated feet are provided in each of the demonstration channels to simulate human feet. Each simulated foot contacts each of the ground simulation boards, and each simulated foot has a groove at both ends.

[0010] Simulated loads are applied to each of the simulated feet to simulate different body weights;

[0011] A posture simulation component is provided in each of the demonstration channels. Each posture simulation component includes a raised rod that is spaced apart from each of the ground simulation boards and a posture simulation block on the raised rod for matching the slots at both ends of each of the simulated feet.

[0012] Simulated sliding rails are provided on both sides of each of the demonstration channels and are slidably connected to the corresponding raised rods. Each of the simulated sliding rails has a gradient rail and a straight rail arranged sequentially from top to bottom. The height of each gradient rail gradually decreases along the sliding direction of each raised rod.

[0013] A sliding simulation component is provided at one end of each of the demonstration channels and is used to apply a gradually increasing resistance to each of the raised rods as the sliding stroke progresses. The sliding simulation component includes a drive member that drives each of the raised rods to slide along each of the demonstration channels, a hinge rod connecting the corresponding raised rod to the drive member, and a gradually increasing resistance member located in the sliding direction of each of the raised rods.

[0014] Furthermore, each of the gradually varying resistance components includes a cylinder, a piston slidably disposed within the cylinder, and a piston rod whose two ends are rotatably connected to the piston and the corresponding elevation rod, respectively. Each piston is provided with a throttling channel connecting both sides, and each cylinder is provided with a throttling rod corresponding to the throttling channel. The diameter of each throttling rod gradually increases along the sliding direction of each elevation rod.

[0015] Furthermore, each of the raised rods is provided with at least two mounting slots arranged circumferentially, and the attitude simulation block is disassembled and installed in any of the mounting slots.

[0016] Furthermore, each of the simulated feet is provided with a load-bearing rod at its top, and each of the load-bearing rods is used to place the simulated load.

[0017] Furthermore, the simulated load includes a plurality of load plates, each of which includes at least two specifications.

[0018] Furthermore, the simulated foot includes a rigid support core and an elastic bionic layer covering the outside of the rigid support core. The elastic bionic layer is made of an elastic material, and the surface of the simulated foot is provided with bionic patterns to simulate the friction coefficient of the human foot.

[0019] Furthermore, it also includes a scene simulation component, which includes a liquid storage chamber and a spray pipe connected to the liquid storage chamber, and the side wall of the spray pipe has spray nozzles that spray towards each of the ground simulation panels.

[0020] Furthermore, the liquid storage chamber is provided with at least two liquid storage areas, each of which is connected to a different spray pipe. Each liquid storage area is used to store simulated liquids with different lubrication states. Each simulated liquid has different lubricity, viscosity or surfactant content, and is used to create different wet and slippery simulated states on the ground simulation board.

[0021] Furthermore, the scene simulation component also includes a liquid collection tank, and the ground simulation board has a liquid collection trough along its edge, with the liquid collection tank connected to the liquid collection trough.

[0022] Furthermore, each of the ground simulation panels is detached and installed in each of the demonstration channels, and each of the ground simulation panels is provided with a limiting seat at its corner.

[0023] The above technical solution has the following advantages, unlike existing technologies:

[0024] This invention, by setting up at least two parallel demonstration channels, allows for the side-by-side comparative demonstration of different footwear samples, different ground simulation boards, different postures, or different simulated loads within the same device. This facilitates the observation of differences in footwear slippage under various demonstration conditions, improving the intuitiveness and educational value of the anti-slip performance demonstration. By setting up simulated feet and simulated loads in each demonstration channel, the stress state of the human foot when wearing footwear and bearing different weights can be simulated, making the demonstration process closer to actual wearing scenarios. By setting up elevation rods and posture simulation blocks, and matching the posture simulation blocks with the grooves at both ends of the simulated foot, different landing postures such as forefoot landing, heel landing, or foot tilt can be simulated, allowing observers to intuitively see the impact of different landing postures on the risk of footwear slippage.

[0025] By using a sliding simulation component in conjunction with a gradient track, the height of the raised rods changes along the gradient track during the sliding process, causing a gradual change in the simulated foot posture. This demonstrates the process of a gradual sliding tendency between the sole of the shoe and the ground as the body's center of gravity shifts, the foot posture changes, and the sliding effect intensifies after the forefoot or heel lands. By using a sliding simulation component in conjunction with a straight track, the component applies a gradually increasing resistance to each raised rod, simulating the initial sliding process of different types of footwear under the same or different conditions. This makes it easier to observe and compare the timing and degree of sliding of different types of footwear under the same or different demonstration conditions. Attached Figure Description

[0052] Please see Figures 1 to 8 This embodiment provides a visual demonstration device for the anti-slip performance of footwear. It is primarily used for new employee training, educational demonstrations, or showcasing new products to suppliers to visually compare and demonstrate the slippage of different types of footwear under various conditions, including different surfaces, slippery environments, foot landing postures, and human loads. This device can be used to demonstrate the anti-slip properties of slippers, sandals, lounge shoes, or other everyday footwear.

[0053] The visual demonstration device for the anti-slip performance of footwear in this embodiment includes at least two parallel demonstration channels 1, a ground simulation board 2, a simulated foot 3, a simulated load 4, a posture simulation component 5, a simulated sliding rail 6, a sliding simulation component 7, and a scene simulation component 8. In this embodiment, two demonstration channels 1 are set up and arranged side by side; in other embodiments, three or more demonstration channels 1 can also be set up to simultaneously compare and display more footwear samples or more demonstration conditions.

[0054] Each demonstration channel 1 forms a relatively independent demonstration space. Each demonstration channel 1 is equipped with a ground simulation board 2, a simulated foot 3, a simulated load 4, a posture simulation component 5, and a set of simulated sliding rails 6. By setting at least two demonstration channels 1 side by side, different footwear samples can be placed in the same demonstration device at the same time, or different ground simulation boards 2, different wet and slippery conditions, different posture simulation block 52 installation states, or different simulated loads 4 can be set in different demonstration channels 1, so that the observer can intuitively see the differences in the order and degree of footwear sliding under different conditions.

[0055] Ground simulation boards 2 are installed in each demonstration channel 1 to simulate the ground in a real-world environment. The ground simulation boards 2 can be tile, wood flooring, stone, plastic, or have a surface with anti-slip texture. Each ground simulation board 2 is detachably installed in its corresponding demonstration channel 1, and each ground simulation board 2 has a limiting seat 21 at its corner. The limiting seat 21 is used to limit the ground simulation board 2, preventing it from shifting due to the slippage of the simulated foot 3 or footwear samples during the demonstration. Simultaneously, the ground simulation board 2 can be lifted upwards to detach from the limiting seat 21 for disassembly. Different materials, textures, or friction characteristics of the ground simulation board 2 can be quickly replaced according to the teaching demonstration needs, thereby achieving a comparative demonstration of the anti-slip properties of footwear under different ground conditions.

[0056] Simulated feet 3 are installed in each demonstration channel 1 to simulate human feet; each simulated foot 3 is in contact with the corresponding ground simulation board 2. During testing or demonstration, the shoes to be demonstrated are placed on the outside of the simulated feet 3 so that the simulated feet 3 can simulate the force state of human feet after wearing shoes; each simulated foot 3 has a groove 31 at both ends, and each groove 31 is formed by extending the simulated foot 3 outward, and is not located at the bottom of the simulated foot 3.

[0057] Specifically, each simulated foot 3 is provided with a load-bearing rod 32 at its top. The simulated foot 3 is used to simulate the shape of the human foot. The load-bearing rod 32 is vertically positioned above the simulated foot 3 and is used to place the simulated load 4. The simulated load 4 includes several load plates, each load plate including at least two specifications, such as load plates of different weight levels. In use, the operator can put different numbers or different specifications of load plates on the load-bearing rod 32 as needed, thereby simulating the pressure exerted on the footwear by users of different weights.

[0058] To make the simulated foot 3 more closely resemble the contact state of a human foot, the simulated foot 3 includes a rigid support core 33 and an elastic bionic layer 34 covering the outside of the rigid support core 33. The rigid support core 33 provides structural support to ensure that the simulated foot 3 does not easily deform under simulated load 4; the elastic bionic layer 34 is made of an elastic material, which can be silicone, rubber, thermoplastic elastomer, polyurethane elastomer, or other materials with flexible rebound properties; the surface of the simulated foot 3 is provided with bionic patterns to simulate the friction coefficient of a human foot. The bionic patterns can be set in the sole area, instep area, or the position in contact with the inner surface of the shoe to simulate the contact friction state between the human foot and the inner surface of the shoe.

[0059] The posture simulation component 5 is installed in each demonstration channel 1. Each posture simulation component 5 includes a raised rod 51 spaced apart from the corresponding ground simulation plate 2 and a posture simulation block 52 installed on the raised rod 51. The posture simulation block 52 can cooperate with one of the slots 31 to form different demonstration postures such as forefoot landing, heel landing, or foot tilting. The raised rod 51 extends along the width direction of the demonstration channel 1, and its two ends are slidably connected to the simulation sliding rails 6 on both sides of the corresponding demonstration channel 1.

[0060] Each elevation rod 51 is provided with at least two circumferentially spaced mounting slots 53, and the posture simulation block 52 can be detachably installed in any of the mounting slots 53. In this embodiment, each elevation rod 51 is provided with two circumferentially spaced mounting slots 53, so that the posture simulation block 52 can be installed at different angular positions of the elevation rod 51 according to different demonstration needs; for example, when the posture simulation block 52 is installed above the elevation rod 51, it can be used to embed into the groove 31 of the corresponding end of the simulated foot 3 and raise that end; when the posture simulation block 52 is installed in other angular positions, the support angle of the posture simulation block 52 on the simulated foot 3 can be changed to change the initial sliding angle of the displayed footwear sample.

[0061] In this embodiment, when the posture simulation block 52 is engaged with the groove 31, one side of the posture simulation block 52 is used to support the bottom of the groove 31, and the side wall of the posture simulation block 52 can abut against the groove wall of the groove 31. When the shim rod 51 slides along the demonstration channel 1 under the drive of the sliding simulation component 7, the posture simulation block 52 can not only raise the corresponding end of the simulated foot 3, but also transmit the sliding action to the simulated foot 3 through the abutment relationship with the groove wall of the groove 31, so that the simulated foot 3 and the footwear sample fitted on the outside of the simulated foot 3 will have a sliding tendency.

[0062] Simulated sliding rails 6 are located on both sides of each demonstration channel 1 and are slidably connected to the corresponding elevation rods 51. Each simulated sliding rail 6 has a gradient rail 61 and a straight rail 62 arranged sequentially from top to bottom. The height of the gradient rail 61 gradually decreases along the sliding direction of the elevation rod 51, and the straight rail 62 extends along the sliding direction of the demonstration channel 1. Pulleys, sliders, or guide ends can be provided at both ends of the elevation rod 51, and the pulleys, sliders, or guide ends slide in cooperation with the simulated sliding rails 6.

[0063] When the two ends of the elevation rod 51 are at the higher end of the gradient rail 61 as the starting point of the slide, the posture simulation block 52 can raise the forefoot or heel of the simulated foot 3, forming an initial posture of raised forefoot, raised heel, or tilted foot. When the slide simulation component 7 drives the elevation rod 51 to slide along the demonstration channel 1, the elevation rod 51 moves along the gradient rail 61. As the height of the gradient rail 61 gradually decreases along the sliding direction, the elevation rod 51 gradually descends during the slide, thereby causing the height of the posture simulation block 52 and the corresponding ends of the simulated foot 3 to gradually change. Through this structure, the process of the shoe sole gradually sliding between the sole and the ground after the forefoot or heel touches the ground during human walking, as the center of gravity of the human body shifts and the foot posture changes, can be simulated.

[0064] When the two ends of the raising rod 51 are located at one end of the straight track 62 as the starting point of the sliding, the raising rod 51 can slide along the straight track 62. The straight track 62 is used to keep the raising rod 51 moving continuously at a relatively stable height, so that the observer can observe the sliding process of the footwear sample in a relatively stable posture. The two ends of the raising rod 51 can detach from the higher end of the gradient track 61 and insert into one end of the straight track 62 to achieve track switching.

[0065] The sliding simulation component 7 is located at one end of each demonstration channel 1. It is used to apply a gradually increasing resistance to each raised rod 51 as the sliding stroke progresses, and to drive each raised rod 51 to slide along each demonstration channel 1. The sliding simulation component 7 includes a drive component 71, a hinge rod 72, and a gradually changing resistance component 73. The drive component 71 is used to provide sliding force. The drive component 71 can be a motor, a linear motor, a cylinder, or an electric push rod. The hinge rod 72 is used to connect the corresponding raised rod 51 to the drive component 71. One end of the hinge rod 72 is connected to the output end of the drive component 71, and the other end is connected to the corresponding raised rod 51. Preferably, it is a hinged connection to accommodate the change in the motion angle of the raised rod 51 when the height changes on the gradually changing track 61, and to avoid jamming during the raising and lowering of the raised rod 51. Specifically, when the driving component 71 is a motor or a linear motor, the driving end of the motor or linear motor is equipped with a gear and a rack meshing with the gear, and the hinge rod 72 is hinged to the rack to achieve a driving connection; when the driving component 71 is a cylinder or an electric push rod, the hinge rod 72 is directly hinged to the driving end of the cylinder. Further, the sliding simulation assembly 7 also includes a controller (not shown in the figure) and an overload detection device (not shown in the figure) electrically connected to the controller. The controller is electrically connected to the driving component 71 and is used to control the start, stop, running speed, and reset actions of the driving component 71. The overload detection device can be one or more of a current detection module, a torque detection module, a tension sensor, or a pressure sensor. In this embodiment, the overload detection device uses a current detection module to detect the operating current of the driving component 71; during the demonstration, when the operating current of the driving component 71 exceeds a preset threshold, the overload detection device sends a detection signal to the controller, and the controller controls the driving component 71 to stop running. The mechanical structure of the drive unit 71 connecting each riser rod 51 and the overload protection logic of the controller and overload detection unit are all existing publicly available technologies and will not be described in detail here.

[0066] The gradually increasing resistance element 73 is located in the sliding direction of each shim rod 51 and is used to provide gradually increasing resistance during the movement of the shim rod 51. In this embodiment, each gradually increasing resistance element 73 includes a cylinder 74, a piston 75 slidably disposed in the cylinder 74, and a piston rod 76 whose two ends are respectively rotatably connected to the piston 75 and the corresponding shim rod 51. Each piston 75 is provided with a throttling channel 77 connecting both sides of the piston 75. Each cylinder 74 is provided with a throttling rod 78 corresponding to the throttling channel 77. The diameter of each throttling rod 78 gradually increases along the sliding direction of each shim rod 51.

[0067] Specifically, when the driving member 71 drives the lifting rod 51 to slide via the hinge rod 72, the lifting rod 51 synchronously drives the piston rod 76 to move. The piston rod 76 drives the piston 75 to slide inside the cylinder 74. When the piston 75 slides, the gas or damping medium inside the cylinder 74 needs to flow through the throttling channel 77 on both sides of the piston 75, thereby generating a damping effect. Since the diameter of the throttling rod 78 gradually increases along the sliding direction of the lifting rod 51, as the piston 75 moves along the cylinder 74, the corresponding diameter of the throttling rod 78 extending into the throttling channel 77 gradually increases, causing the effective flow area of ​​the throttling channel 77 to gradually decrease, thereby causing the damping force on the piston 75 to gradually increase when it moves. Thus, the gradual resistance member 73 can provide the lifting rod 51 with a gradually increasing resistance as the sliding stroke progresses.

[0068] In other preferred embodiments, the piston 75 of each gradual resistance member 73 may not be provided with a throttling channel 77, and the cylinder 74 may not be provided with a throttling rod 78, while still achieving the effect of gradual resistance.

[0069] During the demonstration, each sliding simulation component 7 drives each raised rod 51 to move with the same power. Under the action of the gradually increasing resistance component 73, the different footwear samples in different demonstration channels 1 begin to slide at the starting position. As the resistance of the gradually increasing resistance component 73 increases, the footwear samples that are subject to greater friction on the ground simulation board 2 will stop sliding first, thus forming a direct comparison of the degree of sliding. Different footwear samples correspond to different usage scenarios. By changing different ground simulation boards 2 or different wet and slippery conditions, different usage scenarios can be simulated to change the friction force on the footwear samples from the ground simulation board 2.

[0070] The scene simulation component 8 is used to simulate a slippery ground scenario. The scene simulation component 8 includes a liquid storage chamber 81 and a spray pipe 82 connected to the liquid storage chamber 81. The side wall of the spray pipe 82 has spray nozzles 83 that spray towards various ground simulation panels 2. The liquid storage chamber 81 is located above, to the side, or at the bottom of the demonstration channel 1, and the spray pipe 82 is arranged along the length or width of the demonstration channel 1. In this embodiment, the liquid storage chamber 81 is located at the bottom of the demonstration channel 1, and the spray pipe 82 is arranged along the width of the demonstration channel 1. It is understood that a circulation pump (not shown in the figure) is provided on the connecting pipe between the liquid storage chamber 81 and the spray pipe 82 to provide pressure. The spray pipe 82 does not have a tilting function, meaning the spray nozzles 83 can only spray at one angle, requiring manual scraping to even out the simulated liquid. Compared to adding a tilting function to the spray pipe 82, this solution simplifies the structure and ensures the uniformity of the simulated liquid, avoiding unnecessary variables.

[0071] The liquid storage chamber 81 contains at least two liquid storage areas 84, each connected to a different spray pipe 82. Each liquid storage area 84 stores simulated liquids with different lubrication states, each with different lubricity, viscosity, or surfactant content, to create different simulated wet and slippery conditions on the ground simulation board 2. For example, one liquid storage area 84 can store clean water to simulate a normal wet ground; the other liquid storage area 84 can store a simulated lubricating liquid containing surfactants to simulate soapy water, detergent residue, or a wet and slippery bathroom environment. By selecting different liquid storage areas 84 to spray simulated liquids into different demonstration channels 1, different wet and slippery conditions can be created in the parallel demonstration channels 1, allowing observers to visually see the impact of different wet and slippery conditions on the risk of footwear slippage.

[0072] The scene simulation component 8 also includes a liquid collection tank 85 and a liquid collection trough 86 along the edge of the ground simulation board 2. The liquid collection tank 85 is connected to the liquid collection trough 86. During the demonstration, the simulated liquid sprayed onto the ground simulation board 2 can flow along the surface of the ground simulation board 2 to the edge and flow into the liquid collection trough 86, and then into the liquid collection tank 85. By setting up the liquid collection trough 86 and the liquid collection tank 85, the overflow of simulated liquid is prevented, the interior of the demonstration channel 1 is kept clean, and it is convenient to centrally discharge or recycle the simulated liquid.

[0073] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application.
