Description

Technical Field

[0001] The utility model relates to the field of fitness equipment, in particular to a treadmill with a protective function. Background Art

[0002] As a popular piece of fitness equipment, treadmills play a vital role in modern life. They not only provide users with an indoor running environment that's unrestricted by weather or time, but also help users achieve personalized workout needs through preset parameters such as speed and incline. With technological advancements, treadmills are becoming increasingly versatile, from basic heart rate monitoring and calorie consumption calculations to advanced virtual scene simulations, significantly enhancing the user's exercise experience.

[0003] To address user discomfort or emergencies that may occur while running, some existing treadmills are equipped with safety protection features. A common protection measure involves the use of a safety rope, one end of which is connected to the treadmill's control system and the other end is equipped with a clip. Before using the treadmill, the user needs to clip this clip to their clothing. If the user experiences discomfort while running due to excessive speed or other reasons, and is unable to immediately stop the treadmill via the control panel, the action of leaning backward or falling will cause the rope to straighten. Once the rope reaches the preset tension, the treadmill automatically powers off or slows down, effectively preventing potential injury to the user due to inability to stop the treadmill in a timely manner.

[0004] For those who like to exercise in tight clothing, or for those whose clothing materials or styles are not suitable for clip fastening, this protection mechanism is not flexible and convenient enough. Tight clothing does not have enough space or suitable parts to firmly clamp the safety rope clip, and some clothing with slippery materials or insufficient thickness may cause the clip to accidentally fall off, thus affecting the protection effect. In addition, for users with different body shapes and clothing preferences, a single clip design may not be able to meet the safety and comfort needs of everyone, limiting the wide applicability and user experience of treadmill protection settings.

DETAILED DESCRIPTION

[0023] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0024] It should be noted that like reference numerals denote like items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0025] This embodiment mainly describes the structure of the treadmill, which is as follows:

[0026] A treadmill with protective function, such as Figures 1-6 As shown, the treadmill 1 includes a treadmill 1, a control console 2, a connecting plate 201, a guide frame 202, a first rotating shaft 3, a pull rope 4, a torsion spring 5, a trigger assembly, a fixing frame 9, a locking block 10, a safety belt 11 and an adjustment assembly 12. The treadmill 1 is placed on a stable ground, and a control console 2 is provided on the treadmill 1. The connecting plate 201 and the guide frame 202 are connected below the control console 2. The first rotating shaft 3 is rotatably connected to the guide frame 202 and the connecting plate 201. The pull rope 4 is wound around the portion of the first rotating shaft 3 located below the guide frame 202. A torsion spring 5 is sleeved through the portion passing through the guide frame 202. One end of the torsion spring 5 is connected to the first rotating shaft 3, and the other end is connected to the connecting plate 201. The other end of the pull rope 4 is connected to the locking block 10. One end of the safety belt 11 is wound around the fixing frame 9, and the other end is connected to the locking block 10. The locking block 10 is slidably connected to the fixing frame 9 with an interference fit to maintain a stable connection of the locking block 10. A trigger assembly for shutting down the treadmill 1 is provided on the guide frame 202, and an adjustment assembly 12 for adjusting the extended length of the safety belt 11 is provided on the fixing frame 9.

[0027] like Figure 2 and Figure 3As shown, the trigger assembly includes a screw rod 6, a contact switch 7, an extrusion block 8 and a guide rod 801. One end of the screw rod 6 is rotatably connected to the guide frame 202, and the other end of the screw rod 6 is connected to the first rotating shaft 3. The contact switch 7 is connected to the guide frame 202. The extrusion block 8 is threadedly connected to the screw rod 6. The guide rod 801 is connected to the extrusion block 8. The guide rod 801 is slidably connected to the guide frame 202. The extrusion block 8 is extruded and matched with the contact switch 7. The contact switch 7 is wired to the console 2 for signal transmission.

[0028] like Figure 4 and Figure 5 As shown, the adjustment assembly 12 includes a second rotating shaft 1201, a ratchet ring 1202, an oblique head clamping rod 1203, a first elastic member 1204, an adjustment rod 1205 and a control rod 1206. The second rotating shaft 1201 is rotatably connected to the middle of the fixing frame 9, and the safety belt 11 is wound on the second rotating shaft 1201. Ratchet rings 1202 are provided at both ends of the second rotating shaft 1201. The ratchet ring 1202 is composed of a plurality of ratchets, and the ratchets are respectively provided with a straight surface and an inclined surface. The plane where the straight surface is located passes through the center of the ratchet ring 1202. The second rotating shaft 120 1 is connected to an adjusting rod 1205 at both ends, and a beveled head clamping rod 1203 is slidably connected in the fixing frame 9. The beveled head clamping rod 1203 is also provided with an inclined surface and a straight surface. The straight surface of the beveled head clamping rod 1203 can fit with the straight surface of the ratchet. The top of the beveled head clamping rod 1203 is limitedly matched with the ratchet ring 1202. The bottom of the beveled head clamping rod 1203 is sleeved with a first elastic member 1204. One end of the first elastic member 1204 is connected to the beveled head clamping rod 1203, and the other end is connected to the fixing frame 9. The bottom of the beveled head clamping rod 1203 is connected to the control rod 1206.

[0029] When the user is ready to use the treadmill 1, he first slides the locking block 10 off the fixing frame 9, pulls out the safety belt 11 of an appropriate length according to his waist circumference, wraps it around his waist, and buckles the locking block 10 back to the fixing frame 9 to ensure that the safety belt 11 is firmly wrapped around the user. At this time, the treadmill 1 can be turned on and enters the normal exercise mode.

[0030] When the safety belt 11 is pulled out, the ratchet ring 1202 rotates in the direction of the ratchet inclined surface, so that the inclined surface of the ratchet teeth on the ratchet ring 1202 presses the inclined head clamping rod 1203, and the inclined head clamping rod 1203 slides in the fixing frame 9, compressing the first elastic member 1204. After the ratchet teeth pass through, the first elastic member 1204 makes the inclined head clamping rod 1203 fit with the ratchet ring 1202, preventing the ratchet ring 1202 from rotating. At this time, the safety belt 11 can be properly pulled out. When rewinding in the reverse direction, the ratchet teeth of the ratchet ring 1202 are in close contact with the straight surface of the inclined head clamping rod 1203, preventing reverse rotation, thereby ensuring stable rewinding of the safety belt 11.

[0031] During running, if the user cannot keep up with the running speed and gradually moves backward, the safety belt 11 will be stretched, and the pull rope 4 will be extended. The extension of the pull rope 4 causes the first rotating shaft 3 to rotate, and the first rotating shaft 3 drives the screw rod 6 to rotate and tighten the torsion spring 5. The rotation of the screw rod 6 causes the extrusion block 8 to move along the screw rod 6. The guide rod 801 guides the extrusion block 8 to move linearly toward the contact switch 7. The extrusion block 8 eventually contacts the contact switch 7 and triggers it, thereby sending a command to the control console 2 to quickly shut down the treadmill 1 or slow down the speed to prevent the user from falling due to being unable to keep up with the pace;

[0032] When the user stops exercising, the torsion spring 5 gradually resets and drives the first rotating shaft 3 to rotate, retracting the pull rope 4. The first rotating shaft 3 drives the screw rod 6 to rotate in the opposite direction, so that the extrusion block 8 moves away from the contact switch 7, and the treadmill 1 returns to the standby state and is ready for the next use. If the user needs to remove the safety belt 11, it is first necessary to remove the locking block 10 from the fixing frame 9 and pull the control rod 1206. The control rod 1206 moves to shift the oblique head clamping rod 1203. The oblique head clamping rod 1203 compresses the first elastic member 1204 and disengages from the limit of the ratchet ring 1202. At this time, the adjusting rod 1205 is rotated, and the safety belt 11 will be wound around the second rotating shaft 1201 and retracted, completing the reeling action of the safety belt 11. The user inserts the locking block 10 into the fixing frame 9 to retract the safety belt 11.

[0033] like Figure 5 and Figure 6 As shown, it also includes a support frame 13, a second elastic member 14 and a roller 15. The support frame 13 is slidably connected to the control rod 1206. The roller 15 is rotatably connected to the support frame 13. The roller 15 is squeezed and fitted with the safety belt 11. The second elastic member 14 is sleeved on the bottom of the support frame 13. One end of the second elastic member 14 is connected to the support frame 13, and the other end is connected to the control rod 1206.

[0034] The safety belt 11 contacts the roller 15 during the process of being pulled out and reeled in. The second elastic member 14 pushes the support frame 13 and the roller 15, thereby squeezing the safety belt 11, ensuring that the safety belt 11 remains stable during use without causing discomfort to the user.

[0035] like Figure 4 and Figure 5 As shown, it also includes a protrusion 16 and a magnet 17. The protrusions 16 are connected to both sides of the adjustment rod 1205, and the magnets 17 are connected to the fixing frame 9 and the locking block 10. The two magnets 17 attract each other.

[0036] The rough surface of the protrusion 16 facilitates adjustment of the reeling and extending length of the safety belt 11, and the magnet 17 keeps the locking block 10 stable to prevent it from loosening.

[0037] like Figure 1 、 Figure 2 and Figure 3 As shown, a foam pad 18 is also included. The fixing frame 9 is connected to the foam pad 18 on the side close to the user. The foam pad 18 increases the comfort when the safety belt 11 is fixed.

[0038] like Figure 1 As shown, a protective shell 19 is also included. The bottom of the console 2 is connected to the protective shell 19. The protective shell 19 wraps the connecting plate 201 and the guide frame 202. The protective shell 19 protects the trigger assembly from external influences and improves its stability during use.

[0039] like Figure 1 As shown, a hook 20 is also included. The console 2 is provided with the hook 20 . The hook 20 is used to hang the safety belt 11 , making it easy to hang and store the safety belt 11 .

[0040] Before starting treadmill 1, the user first slides and removes the locking block 10 from the mounting bracket 9, unwinds the safety belt 11, wraps it around the waist, and snaps the locking block 10 back onto the mounting bracket 9. After adjusting the appropriate length, treadmill 1 can be started. During exercise, if the user gradually moves backward due to a speed mismatch, the pull cord 4 is stretched, causing the first rotating shaft 3 to rotate, which in turn rotates the screw 6, causing the squeeze block 8 to move toward the contact switch 7 and eventually trigger it. Upon receiving the signal, the console 2 quickly shuts down or reduces the speed of treadmill 1 to prevent falls. When the user stops, the torsion spring 5 resets, causing the first rotating shaft 3 and screw 6 to rotate in the opposite direction, retracting the pull cord 4 and releasing the squeeze block 8 from the contact switch 7, returning treadmill 1 to standby mode. When extending the safety belt 11, the ratchet ring 1202 rotates clockwise, pushing the oblique head latch 1203, compressing the second elastic member 14 before resetting, ensuring stable extension of the safety belt 11. When rewinding, the ratchet ring 1202 and the oblique head latch 1203 fit together to prevent reverse rotation and maintain stable rewinding. If the user takes off the safety belt 11 , he first removes the locking block 10 , then pulls the control rod 1206 to release the limit of the oblique head clamping rod 1203 , and rotates the adjusting rod 1205 to retract the safety belt 11 .
