Description

Technical Field

[0001] This application belongs to the field of fitness equipment, specifically relating to a treadmill. Background Technology

[0002] Existing treadmills include a running track for users to run on. Users exercise and recover their physical functions by running on the track. As users run on the track, their physical strength decreases, especially when they are physically weak. It is easy for users to not be able to keep up with the speed of the treadmill, and they will fall behind the track. When users are close to the end of the track and still cannot adjust their speed, they are at risk of falling off the track. To avoid accidents on the track, it is necessary to improve the safety features of treadmills.

[0003] A current type of treadmill uses a support frame fixed at a location on the running track, with the frame attached to the base. A safety belt is secured to the support frame, limiting the user's movement to the vicinity of the frame. While the safety belt helps stabilize the user, its fixed position restricts movement within the running track. The user cannot reach the control panel at the front of the track, and the limited space can cause visual discomfort and fatigue. Even when moving away from the support frame towards the front of the track, the safety belt remains taut, preventing the user from using the entire running track and negatively impacting the user experience. Utility Model Content

[0004] This application provides a treadmill to solve the technical problems of existing treadmills where the safety belt restricts the user's range of movement, easily causing user discomfort and preventing the user from using the entire treadmill track.

[0005] The technical solution adopted in this application is as follows: a treadmill, including a base and a running track disposed on the base, characterized in that the treadmill further includes a column disposed on the base, the column being located in front of the running track, a receiving compartment being provided on the side of the column away from the running track, a safety belt being disposed in the receiving compartment and a winding structure rotatably disposed on the column, one end of the safety belt being connected to the winding structure and the other end being connected to the user, the winding structure being able to wind up the safety belt, a safety belt outlet being provided on the side of the column facing the running track, the safety belt outlet being connected to the receiving compartment, and the safety belt extending at least partially out of the safety belt outlet.

[0006] The treadmill in this application also includes the following additional technical features:

[0007] The winding structure is positioned opposite the seat belt outlet. The winding structure includes a rotating shaft and a winding member disposed on the rotating shaft. The axis of the winding member is collinear with the axis of the rotating shaft, and the axis of the winding member is horizontally oriented toward the center position of the seat belt outlet.

[0008] The winding structure also includes an orienting member. The winding member is connected to the orienting member. Along the axial direction of the shaft, the orienting member is located in front of and behind the winding member. Along the axial direction of the shaft, the projection of the winding member is within the projection range of the orienting member.

[0009] The safety belt includes a body-fitting section for connection with the user, a starting section for connection with the winding structure, and an extension section connecting the body-fitting section and the starting section. The safety belt also includes a limiting member provided at the end of the extension section near the body-fitting section, the limiting member being used to abut against the upright.

[0010] The length of the safety belt is less than the horizontal distance from the end of the runway to the connection point between the starting section and the winding structure.

[0011] A sensor is located below the winding structure to detect the length of the seat belt that has detached from the winding structure.

[0012] The sensor includes a lead wire and a reset component. The treadmill has an additional structure that connects to the winding structure. The additional structure is connected to the lead wire, and the reset component drives the winding structure to wind up the safety belt.

[0013] The winding structure also includes a return element, which is connected to the winding structure and can drive the winding structure to wind up the safety belt.

[0014] The treadmill also includes handrail structures on the left and right sides of the track. One end of the handrail structure is connected to the upright, and the other end extends towards the rear of the upright and is connected to the tail end of the base.

[0015] The treadmill has two emergency stop switches spaced apart on the handrail structure, and the surface of the handrail structure between the two emergency stop switches is made of frosted material.

[0016] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0017] 1. This application utilizes a safety belt and a winding structure. One end of the belt connects to the winding structure, and the other end connects to the user. The safety belt provides protection for the user, and the winding structure can retract the safety belt. The safety belt follows the user, providing assistance throughout movement on the track. The combined action of the winding structure and the user keeps the safety belt under tension, preventing slack between the winding structure and the user. In emergencies, the safety belt responds quickly to protect the user. Furthermore, by placing the winding structure on a pillar in front of the track, the safety belt applies force evenly through the connection point with the user in emergencies, improving comfort. The safety belt can be dynamically adjusted during running, such as by being retracted by the winding structure or by the user stretching the belt, effectively preventing knots or bends and improving smoothness during use. By ensuring at least part of the safety belt extends beyond the outlet, the connection between the user and the safety belt is facilitated, enhancing the user experience.

[0018] 2. As a preferred embodiment of this application, by setting the winding structure opposite to the seat belt outlet, the angle at which the seat belt extends from the seat belt outlet is optimized, improving the smoothness of dynamic adjustment of the seat belt during use. By setting the axis of the retractor to be horizontally oriented towards the center of the seat belt outlet, it is ensured that the seat belt accurately enters and exits during winding and release, avoiding seat belt twisting and jamming caused by positional deviation, and improving the smoothness and reliability of seat belt use.

[0019] Furthermore, by setting a guide member, the projection of the winding member falls within the projection range of the guide member. When the seat belt is wound around the winding member, the guide member restricts the displacement of the seat belt along the axis of rotation, allowing the seat belt to be wound around the winding member in an orderly manner. This prevents the seat belt from tangling or knotting, improving the winding efficiency of the seat belt. At the same time, it also improves the efficiency of the seat belt detaching from the winding structure.

[0020] 3. In a preferred embodiment of this application, a limiting member is provided to abut against the upright. The limiting member keeps the body-hugging section outside the seat belt exit, facilitating the user's operation of the body-hugging section. Due to the abutment between the limiting member and the upright, the body-hugging section can be in a relaxed state, allowing the user to wear the body-hugging section more easily and optimizing the user experience.

[0021] Furthermore, by setting the length of the safety belt to be less than the horizontal distance from the end of the track to the connection point between the starting section and the winding structure, the safety belt can serve as a limiting reminder. Before the user reaches the end of the track, the safety belt applies force to the user through the body-hugging section to remind the user that the current position is close to the end of the track and that the user needs to adjust their position or stop running. On the other hand, during normal running, the safety belt will not cause excessive swaying and interfere with the user's movement due to its excessive length, and it can accurately restrict the user's position when the user approaches the end of the track. This ensures that the safety belt is precisely adapted to the user's range of motion, providing effective restraint at critical moments and ensuring the user's safety.

[0022] 4. In a preferred embodiment of this application, a sensor is disposed below the winding structure. The sensor is used to detect the length of the seat belt detached from the winding structure, obtain the status of the seat belt in real time, and collect dynamic information about the seat belt. The sensor is disposed below the winding structure and can closely cooperate with the winding structure to monitor the retraction and extension of the seat belt in real time.

[0023] Furthermore, by configuring the sensor, including a lead wire and a reset component, and connecting the additional structure to the lead wire, the reset component drives the winding structure to rewind the safety belt. The additional structure is connected to the winding structure, and the connection position of the lead wire is relatively fixed, reducing the possibility of loosening due to shaking or friction during movement, thus ensuring the accuracy of the sensor's detection of the length of the safety belt detached from the winding structure. On the one hand, the sensor can provide real-time feedback on the length of the safety belt detached from the winding structure via the lead wire; on the other hand, the reset component drives the winding structure to rewind the safety belt via the lead wire, achieving functional integration, making reasonable use of the column space, and improving the overall compactness of the treadmill structure.

[0024] 5. As a preferred embodiment of this application, by setting a return component, the return component drives the winding structure to rewind the seat belt, thereby realizing the dynamic adjustment of the seat belt, avoiding excessive looseness and shaking of the seat belt during the user's movement, reducing the swing amplitude of the seat belt, and improving the protective effect of the seat belt.

[0025] Furthermore, by incorporating a handrail structure, with one end connected to the upright and the other extending towards the rear of the upright and connecting to the tail end of the base, the handrail structure expands the lateral protection range for users. The connection to the tail end of the base also provides some protection for the user's rear, forming a relatively large and complete protection area. The handrail structure works in conjunction with the safety belt to achieve multi-directional protection. The safety belt primarily restrains the user's displacement range, preventing them from rushing across the treadmill's safe zone; while the handrail structure provides support and restraint from the front, sides, and rear, comprehensively improving the treadmill's safety protection effect.

[0026] Furthermore, by installing two emergency stop switches at intervals on the handrail structure, users can easily operate these switches. The handrail structure provides support for the user's grip, and the user's hand can move slightly along the handrail to trigger the emergency stop switch in an emergency, ensuring timely activation. The handrail surface between the two emergency stop switches is made of a frosted material. This increases friction between the user and the handrail, making it easier to grip and improving the user experience. Additionally, the emergency stop switches can delineate areas, allowing users to clearly identify their location through tactile feedback, further optimizing the user experience.

[0049] like Figure 1 , Figure 3 , Figure 4 As shown, a treadmill includes a base 1 and a running track 11 disposed on the base 1. The treadmill also includes a column 2 disposed on the base 1, the column 2 being located in front of the running track 11. A receiving compartment 21 is provided on the side of the column 2 away from the running track 11. A safety belt 3 and a winding structure 4 rotatably disposed on the column 2 are provided in the receiving compartment 21. One end of the safety belt 3 is connected to the winding structure 4, and the other end is connected to the user. The winding structure 4 can wind up the safety belt 3. A safety belt outlet 22 is provided on the side of the column 2 facing the running track 11. The safety belt outlet 22 is connected to the receiving compartment 21, and the safety belt 3 extends at least partially out of the safety belt outlet 22.

[0050] This application incorporates a safety belt 3 and a winding structure 4. One end of the belt connects to the winding structure 4, and the other end connects to the user. The safety belt 3 provides safety protection for the user, and the winding structure 4 can retract the safety belt 3. The safety belt 3 follows the user, providing assistance throughout the user's movement on the track 11. The combined action of the winding structure 4 and the user keeps the safety belt 3 under tension, preventing slack between the winding structure 4 and the user. In case of emergency, the safety belt 3 can respond quickly and protect the user. Furthermore, by placing the winding structure 4 on the upright 2, located in front of the track 11, the safety belt 3 can apply force evenly through the connection point with the user in case of an emergency, improving the comfort of using the safety belt 3. During the user's running process, the safety belt 3 can be dynamically adjusted, such as being retracted by the winding structure 4 or stretched by the user, effectively preventing knots or bends and improving the smoothness of use. By setting the seat belt 3 to extend at least partially out of the seat belt outlet 22, it is easier for the user to connect with the seat belt 3, thus improving the user experience.

[0051] In this application, the winding structure 4 can be configured in any of the following embodiments:

[0052] Implementation method one: such as Figure 3 , Figure 4 , Figure 5 As shown, the winding structure 4 is disposed opposite to the seat belt outlet 22. The winding structure 4 includes a rotating shaft 41 and a take-up member 42 disposed on the rotating shaft 41. The axis of the take-up member 42 is collinear with the axis of the rotating shaft 41, and the axis of the take-up member 42 is horizontally oriented towards the center of the seat belt outlet 22. Preferably, the outer contour of the seat belt outlet 22 is provided with rounded corners to avoid the seat belt outlet 22 damaging the seat belt 3.

[0053] By setting the winding structure 4 opposite to the seat belt outlet 22, the angle at which the seat belt 3 extends from the seat belt outlet 22 is optimized, improving the smoothness of dynamic adjustment of the seat belt 3 during use. By setting the axis of the retractor 42 to be horizontally oriented towards the center of the seat belt outlet 22, the seat belt 3 can be ensured to move in and out accurately during winding and release, avoiding twisting or jamming of the seat belt 3 due to positional deviation, thus improving the smoothness and reliability of the seat belt 3 in use.

[0054] Implementation Method 2: This implementation method is not illustrated. The winding structure is arranged opposite to the seat belt outlet. The winding structure includes a rotating shaft and a winding member disposed on the rotating shaft. The axis of the winding member is collinear with the axis of the rotating shaft. The top end of the winding member points horizontally towards the center position of the seat belt outlet. The axis of the winding member is horizontally above the lower edge of the seat belt outlet.

[0055] Implementation Method 3: This implementation method 3 is not illustrated. The difference from implementation method 2 is that the bottom end of the retractor points horizontally towards the center of the seat belt outlet, and the axis of the retractor is horizontally located below the upper edge of the seat belt outlet.

[0056] In Embodiment 1, Embodiment 2 and Embodiment 3, this application does not limit the rotational arrangement of the winding structure 4. The rotating shaft 41 can be fixed to the column 2, the winding structure 4 includes a bearing connected to the rotating shaft 41, and the winding structure 4 is rotatably arranged on the rotating shaft 41, or the winding structure 4 is fixedly arranged on the rotating shaft 41, and the column 2 is provided with a bearing that cooperates with the rotating shaft 41, so that the rotating shaft 41 can be rotatably arranged on the column 2.

[0057] In Embodiment 1, Embodiment 2, and Embodiment 3, the limiting setting of the seat belt 3 in the winding structure 4 can be any one of the following embodiments:

[0058] Example 1: As Figure 5As shown, the winding structure 4 also includes an orienting member 43. The winding member 42 is connected to the orienting member 43. Along the axial direction of the rotating shaft 41, the orienting member 43 is disposed in front of and behind the winding member 42. Along the axial direction of the rotating shaft 41, the projection of the winding member 42 is within the projection range of the orienting member 43. In embodiment 1, the winding member 42 can be a cylinder, or the winding member 42 can include multiple rods arranged in a single-layer circular array around the axis of the rotating shaft 41. This application does not impose any limitations. In embodiment 1, the orienting member 43 can be connected to the winding member 42, or the orienting member 43 can be connected to both the winding member 42 and the rotating shaft 41.

[0059] By setting the orienting member 43, the projection of the winding member is within the projection range of the orienting member 43. When the seat belt 3 is wound around the winding member, the orienting member 43 restricts the displacement of the seat belt 3 along the axis of the rotating shaft 41, so that the seat belt 3 can be wound around the winding member in an orderly manner, which can prevent the seat belt 3 from tangling or knotting and improve the winding efficiency of the seat belt 3. At the same time, it can also improve the efficiency of the seat belt 3 detaching from the winding structure 4.

[0060] Example 2: This example 2 is not shown in the figure. The winding component is provided with a positioning groove. The positioning groove has a limiting wall that is arranged opposite to the axis of rotation. The safety belt is wound around the positioning groove.

[0061] In this application, the seat belt 3 can be installed in any of the following embodiments:

[0062] Implementation Method Four: (e.g.) Figure 5 , Figure 6 , Figure 7 As shown, the seat belt 3 includes a body-hugging section 31 for connection with the user, a starting section 32 connected to the winding structure 4, and an extension section 33 connecting the body-hugging section 31 and the starting section 32. The seat belt 3 also includes a limiting member 34 disposed at one end of the extension section 33 near the body-hugging section 31, the limiting member 34 being used to abut against the upright 2. The limiting member 34 extends vertically, and the thickness of the limiting member 34 and the extension section 33 is greater than the height of the seat belt outlet 22; or the limiting member 34 extends laterally, and the width of the limiting member 34 and the extension section 33 is greater than the width of the seat belt outlet 22.

[0063] By setting a limiting member 34, which abuts against the upright 2, the body-hugging section 31 is positioned outside the seat belt exit 22, facilitating user operation of the body-hugging section 31. Because the limiting member 34 abuts against the upright 2, the body-hugging section 31 can be in a relaxed state, allowing the user to better wear it and optimizing the user experience.

[0064] Implementation Method 5: This implementation method is not illustrated. A sensor is provided below the winding structure. The sensor is used to detect the length of the safety belt detached from the winding structure and the length of the safety belt wound by the winding structure. The sensor includes a lead wire and a reset component. The treadmill is provided with an additional structure that connects to the winding structure. The additional structure is connected to the lead wire. The reset component drives the winding structure to wind up the safety belt. After the winding structure winds up a certain length of the safety belt, the sensor stops winding the safety belt, so that at least part of the safety belt extends out of the safety belt outlet.

[0065] As a preferred embodiment 3 under implementation method four: In embodiment 3 (not illustrated), the length of the safety belt is less than the horizontal distance from the end of the track to the connection point between the starting section and the winding structure. By setting the length of the safety belt to be less than the horizontal distance from the end of the track to the connection point between the starting section and the winding structure, on the one hand, the safety belt can serve as a limiting reminder. Before the user reaches the end of the track, the safety belt applies force to the user through the body-hugging section to remind the user that the current position is close to the end of the track and that position adjustment or stopping running training is required. On the other hand, during normal running, the safety belt will not cause excessive swaying and interference with movement due to its excessive length, and it can accurately restrict the user's position when the user approaches the end of the track, so that the safety belt is precisely adapted to the user's range of motion, providing effective restraint at critical moments and ensuring the safety of the user.

[0066] As a preferred embodiment of this application, the sixth method is as follows: Figure 5 As shown, a sensor 5 is located below the winding structure 4. The sensor 5 is used to detect the length of the seat belt 3 that has detached from the winding structure 4. By placing the sensor 5 below the winding structure 4, the sensor 5 can detect the length of the seat belt 3 that has detached from the winding structure 4, thereby obtaining real-time information on the status of the seat belt 3 and collecting dynamic information about the seat belt 3. The sensor 5 is located below the winding structure 4 and can work closely with the winding structure 4 to monitor the retraction and extension of the seat belt 3 in real time.

[0067] In implementation method six, the sensor 5 can be set up in any of the following embodiments:

[0068] Example 4: Figure 5As shown, sensor 5 includes lead wire 51 and reset component (not shown in the attached diagram). The treadmill is equipped with an additional structure 6 that connects to the winding structure 4. The additional structure 6 is connected to lead wire 51, and the reset component drives the winding structure 4 to wind up the safety belt 3. Furthermore, the additional structure 6 includes a limiting plate connected to the rotating shaft 41 and multiple connecting rods connected to the winding structure 4. The multiple connecting rods are distributed in a single circle around the axis of the rotating shaft 41. By setting sensor 5 to include lead wire 51 and reset component, and the additional structure 6 connected to lead wire 51, the reset component drives the winding structure 4 to wind up the safety belt 3. The connection position of lead wire 51 is relatively fixed, reducing the possibility of loosening due to shaking or friction during movement, and ensuring the accuracy of sensor 5 in detecting the length of safety belt 3 detached from the winding structure 4. On the one hand, the sensor 5 can provide real-time feedback on the length of the safety belt 3 detached from the winding structure 4 through the lead wire 51. On the other hand, the reset component drives the winding structure 4 to wind the safety belt 3 through the lead wire 51, thereby achieving functional integration, making reasonable use of the space of the column 2, and improving the overall compactness of the treadmill structure.

[0069] Example 5: This example 5 is not illustrated. The sensor is an infrared sensor. The length of the seat belt detached from the winding structure is counted by counting the number of rotations of the winding structure. Those skilled in the art will understand that when using an infrared sensor, the sensor can be placed below the winding structure, or it can be placed on one side of the winding structure, as shown on the left or right side in the figure.

[0070] In this application, the winding configuration of the winding structure 4 can be any of the following embodiments:

[0071] Embodiment Seven: This embodiment seven is not illustrated. The winding structure further includes a return element, which is connected to the winding structure and can drive the winding structure to wind up the seat belt. Further, the return element is a coil spring, one end of which is fixed to the column, and the other end is connected to the winding structure. Those skilled in the art will understand that the return element may include a drive motor, and the output shaft of the drive motor is connected to the winding structure.

[0072] By incorporating a return mechanism, which drives the winding structure to retract the seat belt, dynamic adjustment of the seat belt is achieved. This prevents the seat belt from becoming too loose and wobbly during the user's movement, reduces the swing amplitude of the seat belt, and improves the protective effect of the seat belt.

[0073] Implementation Method 8: This implementation method 8 is not illustrated. The difference from implementation method 7 is that the return component is connected to the rotating shaft.

[0074] Implementation Method Nine: A sensor 5 is located below the winding structure 4. The sensor 5 is used to detect the length of the safety belt 3 detached from the winding structure 4. The sensor 5 includes a lead wire 51 and a reset component. The treadmill has an additional structure 6 connected to the winding structure 4. The additional structure 6 is connected to the lead wire 51. The reset component drives the winding structure 4 to wind up the safety belt 3. By using the reset component of the sensor 5 to drive the winding structure to wind up the safety belt 3, a compact design of the treadmill is achieved. The sensor 5 can also monitor the length data of the safety belt 3 in real time, providing more direct and accurate feedback on the relevant information of the safety belt 3.

[0075] In this application, the handrail structure 7 of the treadmill can be configured in any of the following embodiments:

[0076] Implementation Method 10: As Figure 1 , Figure 3 , Figure 4 As shown, the treadmill also includes handrail structures 7 located on the left and right sides of the running track 11. One end of the handrail structure 7 is connected to the upright column 2, and the other end extends toward the rear of the upright column 2 and is connected to the tail end of the base 1.

[0077] By incorporating a handrail structure 7, one end of which connects to the upright 2, and the other end extending towards the rear of the upright 2 and connecting to the tail end of the base 1, the handrail structure 7 expands the lateral protection range for users. The connection between the handrail structure 7 and the tail end of the base 1 also provides some protection to the rear of the user, forming a relatively large and complete protection range. The handrail structure 7 works in conjunction with the safety belt 3 to achieve multi-directional protection. The safety belt 3 primarily restrains the user's displacement range, preventing the user from rushing across the treadmill's safety zone; while the handrail structure 7 provides support and restraint from the front, sides, and rear, comprehensively improving the treadmill's safety protection effect.

[0078] Implementation Method Eleven: This Implementation Method Eleven is not illustrated. The treadmill also includes handrail structures located on the left and right sides of the running track. One end of the handrail is connected to the base, and the other end extends toward the rear of the column and is connected to the tail end of the base.

[0079] As a preferred embodiment of implementation method ten: 6, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the treadmill has two emergency stop switches 8 spaced apart on the handrail structure 7, and the surface of the handrail structure 7 between the two emergency stop switches 8 is made of frosted material. Those skilled in the art will understand that the number of emergency stop switches 8 in this application is not limited; it can be the two emergency stop switches 8 shown in Embodiment 6, or multiple emergency stop switches 8 can be provided.

[0080] Two emergency stop switches 8 are spaced apart on the handrail structure 7, facilitating user operation. The handrail structure 7 provides support for the user's grip, and the user's hand can move slightly on the handrail structure 7 to trigger the emergency stop switch 8 in an emergency, ensuring timely activation. The surface of the handrail structure 7 between the two emergency stop switches 8 is made of a frosted material. This increases friction between the user and the handrail structure 7, improving grip and user experience. Furthermore, the emergency stop switches 8 can delineate areas, allowing users to clearly identify their location through tactile feedback, further optimizing the user experience.
