Description

Technical Field

[0001] This invention belongs to the field of running aid technology, and more specifically, relates to a running aid device for track and field training in sports. Background Technology

[0002] Among the many track and field events, running is undoubtedly one of the most direct displays of an athlete's physical talent and athletic level. Its tense and exciting pace and ever-changing situation consistently attract the attention of countless spectators. At the racecourse, each track is carefully equipped with starting blocks. As professional track and field equipment, these starting blocks are scientifically designed to provide athletes with a powerful and stable force at the moment of takeoff. Athletes utilize this force to more efficiently initiate their movements, achieving a rapid acceleration and gaining an advantage from the start, laying a solid foundation for the rest of the race.

[0003] A common and impactful problem exists in the running runners used in current track and field training: after prolonged training, athletes inevitably accumulate dust on their shoe soles. During frequent use of the running runners, this dust is transferred to the footplates. If not cleaned regularly, a large amount of dust will gradually adhere to the footplate surface. This dust accumulation alters the original coefficient of friction of the footplates, making the surface relatively smooth. Consequently, the anti-slip efficiency of the running runners is significantly reduced, undoubtedly posing a safety hazard to athletes and affecting the quality and effectiveness of training. Summary of the Invention

[0004] In view of the problems in the related technologies, the present invention proposes a track and field training approach device for sports, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a running start device for track and field training, comprising two running start fixing plates. Sliding blocks are slidably connected within the two running start fixing plates. Connectors are fixedly mounted on the sliding blocks, and each connector has a first sliding groove. An electromagnetic induction groove is disposed within the first sliding groove, and the electromagnetic induction groove is electrically connected to an electromagnetic sensor. The electromagnetic sensor is fixedly mounted on a sliding rod and is used to control the activation of an air pump. The air pump is fixedly mounted on a foot pedal base, which is fixedly connected to the sliding rod. A return spring is disposed between the sliding rod and the first sliding groove. The sliding rod is slidably connected within the first sliding groove. Both ends of the air pump are connected to an exhaust port via air supply pipes, and the other end of the air pump is fixedly connected to an air inlet pipe. The exhaust port is located on the foot pedal base, which has a rotatable foot pedal. When the athlete presses the foot pedal, the electromagnetic sensor is triggered, and the air pump starts to draw in air. After the athlete runs, the air pump exhausts air, cleaning dust from the surface of the foot pedal.

[0006] Furthermore, the running start fixing plate has a second sliding groove, the sliding block is slidably connected inside the second sliding groove, a first threaded rod is rotatably installed inside the second sliding groove, the sliding block is threadedly connected to the first threaded rod, and a handle is fixedly installed at one end of the first threaded rod. The position of the sliding block in the second sliding groove can be adjusted by rotating the handle.

[0007] Furthermore, one end of the return spring is fixedly mounted on the sliding rod, and the other end is fixedly mounted on the first sliding groove. The vent holes are evenly distributed on both sides of the foot pedal base. The foot pedal is controlled by a rotating assembly, which has self-locking properties. The surface of the foot pedal is provided with anti-slip threads to enhance the friction when the athlete steps on it.

[0008] Furthermore, one of the running start mounting plates is rotatably mounted with a threaded cylinder, and one end of a second threaded rod is threadedly connected to the inside of the threaded cylinder. The other end of the second threaded rod is rotatably mounted on the other running start mounting plate. One of the running start mounting plates is fixedly mounted with one end of a telescopic rod, and the other end of the telescopic rod is fixedly mounted on the other running start mounting plate. The distance between the two running start mounting plates can be adjusted by rotating the threaded cylinder.

[0009] Furthermore, a worm gear is fixedly installed on the threaded cylinder, the worm gear meshes with a worm, and the worm is rotatably installed on one of the running start fixing plates. By rotating the worm, the worm gear and the threaded cylinder can be driven to rotate.

[0010] Furthermore, the foot pedal is adhered to the rotating plate with high-viscosity pressure-sensitive adhesive, and the rotating plate is rotatably mounted on the running start fixing plate, which facilitates the installation and replacement of the foot pedal.

[0011] Furthermore, both of the running start plates are fixedly installed with anti-slip plates and rivets at their bottoms. There are several rivets, and the anti-slip plates are made of rubber with anti-slip textures on their bottom surfaces. The rivets are evenly distributed in a matrix at the four corners of the bottom of the running start plates to enhance the fixation effect between the running start plates and the ground.

[0012] Furthermore, a suction cup is fixedly installed at the bottom of the running approach plate. Several suction cups are provided. The suction cups have good sealing properties and are made of rubber. When the athlete steps on the foot pedal, the suction cups are forcefully attached to the ground, further enhancing the stability of the running approach equipment.

[0013] Compared with the prior art, the present invention has the following advantages: 1. This equipment features an automatic cleaning function, facilitating daily maintenance. When the athlete steps on the foot pedal, it causes the sliding rod to slide, allowing the electromagnetic sensor to enter the electromagnetic induction slot, triggering the air pump to draw in air. After the athlete runs out, the pressure disappears, the return spring pushes the sliding rod in the opposite direction, the electromagnetic sensor leaves the electromagnetic induction slot, the air pump stops drawing in air and begins to expel air. The air is ejected through the air supply pipe from the exhaust holes evenly distributed on both sides of the foot pedal base, cleaning dust from the foot pedal surface. Furthermore, the foot pedals are adhered to the rotating plate with high-viscosity pressure-sensitive adhesive, allowing for easy removal and replacement when wear occurs after long-term use or when different sizes need to be changed, reducing maintenance costs.

[0014] 2. The equipment exhibits excellent stability, providing reliable support for athletes' training. The anti-slip plate at the bottom of the running start plate is made of rubber with anti-slip texture, increasing friction with the ground; rivets are evenly distributed in a matrix at the four corners of the bottom of the running start plate, further enhancing the fixation effect between the equipment and the ground; the suction cups have good sealing properties and can firmly adhere to the ground under force. Multiple anti-slip fixing measures effectively prevent the equipment from moving during use, ensuring the safety of athletes during training.

[0015] 3. This running start device is highly adjustable, meeting the diverse needs of different athletes. On one hand, by rotating the handle on the first threaded rod, the position of the sliding block within the second groove can be adjusted, thereby changing the layout of related components. On the other hand, rotating the worm gear drives the worm wheel and threaded cylinder to adjust the distance between the two running start fixing plates. Simultaneously, the telescopic rod provides auxiliary support and guidance, ensuring a smooth adjustment process. Furthermore, the foot pedals can be flexibly adjusted and fixed via a rotating assembly or rotating plate, allowing athletes to find the most comfortable pedaling angle according to their own habits, improving the training experience and effectiveness.

[0016] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the invention.

[0021] In the description of this invention, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the invention.

[0022] Please see Figures 1-7As shown, this invention is a track and field training approach device for sports, including a running approach plate 1. Two running approach plates 1 are provided, and sliding blocks 2 are slidably connected inside the two running approach plates 1. Connecting parts 3 are fixedly installed on the sliding blocks 2. The connecting parts 3 have a first sliding groove 4. An electromagnetic induction groove 5 is provided inside the first sliding groove 4. The electromagnetic induction groove 5 is electrically connected to an electromagnetic sensor 6. The electromagnetic sensor 6 is fixedly installed on a sliding rod 7 and is used to control the opening of an air pump 8. The air pump 8 is fixedly installed on a foot pedal base 9. The foot pedal base 9 is fixedly connected to the sliding rod 7. A return spring 10 is provided between the sliding rod 7 and the first sliding groove 4. The sliding rod 7 is slidably connected inside the first sliding groove 4. Both ends of the air pump 8 are connected to an exhaust port 12 through an air supply pipe 11. The other end of the air pump 8 is fixedly connected to an air inlet pipe 13. The exhaust port 12 is opened on the foot pedal base 9. A foot pedal 16 is rotatably provided on the foot pedal base 9. When the athlete steps on the foot pedal 16, the electromagnetic sensor 6 senses the pressure change and controls the air pump 8 to start inhaling; after the athlete runs, the air pump 8 exhausts the air and cleans the dust on the surface of the foot pedal 16 through the exhaust port 12.

[0023] The working principle of the track and field training run-up device proposed in this invention is as follows: when the track and field training run-up device is working, in the initial state, the sliding rod 7 is located in the first sliding groove 4, the return spring 10 is in the natural state, the electromagnetic sensor 6 is not in the electromagnetic induction groove 5, and the air pump 8 is in the off state.

[0024] When the athlete presses down on the foot pedal 16, the foot pedal 16, under pressure, moves the foot pedal base 9. The foot pedal base 9 then moves the sliding rod 7, which is fixedly connected to it, within the first sliding groove 4. As the sliding rod 7 slides, the electromagnetic sensor 6, fixedly mounted on the sliding rod 7, enters the electromagnetic induction groove 5 inside the first sliding groove 4. The two are electrically connected. After sensing this change, the electromagnetic sensor 6 sends a signal to control the air pump 8 to start. After the air pump 8 starts, it draws in air through the air intake pipe 13, which is fixedly connected to one end.

[0025] After the athlete runs, the pressure on the foot pedal 16 disappears. Under the elastic action of the return spring 10 set between the sliding rod 7 and the first sliding groove 4, the return spring 10 restores its deformation, pushing the sliding rod 7 to slide back to its initial position within the first sliding groove 4. At this time, the electromagnetic sensor 6 leaves the electromagnetic induction groove 5, the air pump 8 stops sucking in air and begins to exhaust air. The two ends of the air pump 8 are connected to the exhaust holes 12 opened on the foot pedal base 9 through the air supply pipe 11. The air discharged by the air pump 8 is sprayed out from the exhaust holes 12 through the air supply pipe 11 to clean the dust on the surface of the foot pedal 16. Afterwards, the equipment returns to its initial state, ready for the next use.

[0026] In one embodiment, the running start fixing plate 1 is provided with a second slide groove 14, and a sliding block 2 is slidably connected inside the second slide groove 14. A first threaded rod 15 is rotatably installed inside the second slide groove 14. The sliding block 2 is threadedly connected to the first threaded rod 15. A handle 27 is fixedly installed at one end of the first threaded rod 15. By rotating the handle 27, the first threaded rod 15 can be rotated, thereby adjusting the position of the sliding block 2 in the second slide groove 14.

[0027] In one embodiment, for the aforementioned return spring 10, one end of the return spring 10 is fixedly installed on the sliding rod 7, and the other end is fixedly installed on the first sliding groove 4. The exhaust holes 12 are evenly distributed on both sides of the foot pedal base 9. The foot pedal 16 is controlled by the rotating assembly 17, which has self-locking properties. The surface of the foot pedal 16 is provided with anti-slip threads to improve the friction when the athlete steps on it and prevent slipping.

[0028] The working principle of the track and field training approach device proposed in this invention is as follows: In the initial state, the sliding block 2 is located at a specific position in the second slide groove 14 opened in the approach fixing plate 1, the sliding rod 7 is in the first slide groove 4, the return spring 10 is in a naturally extended state, the electromagnetic sensor 6 is not in the electromagnetic induction groove 5, the air pump 8 is in a closed state, and the foot pedal 16 is fixed at a suitable angle by the self-locking rotating component 17.

[0029] When the position of the sliding block 2 within the second slide groove 14 needs to be adjusted according to the different needs of the athlete, the handle 27 fixedly installed at one end of the first threaded rod 15 is rotated. The handle 27 drives the first threaded rod 15 to rotate within the second slide groove 14. Since the sliding block 2 is threadedly connected to the first threaded rod 15, the sliding block 2 will move linearly along the second slide groove 14 during the rotation of the first threaded rod 15, thereby adjusting to the required position.

[0030] When the athlete presses down on the foot pedal 16, the foot pedal 16, under pressure, moves the foot pedal base 9. The foot pedal base 9 then moves the sliding rod 7, which is fixedly connected to it, within the first sliding groove 4. As the sliding rod 7 slides, the electromagnetic sensor 6, fixedly mounted on the sliding rod 7, enters the electromagnetic induction groove 5 inside the first sliding groove 4. The two are electrically connected. After sensing this change, the electromagnetic sensor 6 sends a signal to control the air pump 8 to start. After the air pump 8 starts, it draws in air through the air intake pipe 13, which is fixedly connected to one end.

[0031] After the athlete runs, the pressure on the foot pedal 16 disappears. At this time, one end of the return spring 10 is fixed to the sliding rod 7, and the other end is fixed to the first slide groove 4. Under the elastic action of the return spring 10, the return spring 10 restores its deformation and pushes the sliding rod 7 to slide back to its initial position in the first slide groove 4. At this time, the electromagnetic sensor 6 leaves the electromagnetic induction groove 5, the air pump 8 stops sucking in air and starts venting air. The two ends of the air pump 8 are connected to the exhaust holes 12 evenly distributed on both sides of the foot pedal base 9 through the air supply pipe 11. The air discharged by the air pump 8 is sprayed out from the exhaust holes 12 through the air supply pipe 11 to clean the dust on the surface of the foot pedal 16.

[0032] Throughout use, the anti-slip threads on the surface of the foot pedal 16 increase friction when the athlete steps on it, preventing slippage. The angle of the foot pedal 16 can be adjusted and fixed as needed via the self-locking rotating assembly 17. Afterward, the device returns to its initial state, ready for the next use.

[0033] In one embodiment, for the aforementioned running start fixing plate 1, one of the running start fixing plates 1 is rotatably mounted with a threaded cylinder 18, and the internal thread of the threaded cylinder 18 is connected to one end of a second threaded rod 19. The other end of the second threaded rod 19 is rotatably mounted on another running start fixing plate 1. One of the running start fixing plates 1 is fixedly mounted with one end of a telescopic rod 20, and the other end of the telescopic rod 20 is fixedly mounted on another running start fixing plate 1. The distance between the two running start fixing plates 1 can be adjusted by rotating the threaded cylinder 18. The telescopic rod 20 plays an auxiliary support and guiding role.

[0034] In one embodiment, the threaded cylinder 18 is fixedly mounted with a worm gear 21, which meshes with a worm 22. The worm 22 is rotatably mounted on one of the running start fixing plates 1. By rotating the worm 22, the worm gear 21 and the threaded cylinder 18 can be driven to rotate, thereby adjusting the distance between the two running start fixing plates 1.

[0035] In one embodiment, the foot pedal 16 is adhered to the rotating plate 23 by a high-viscosity pressure-sensitive adhesive. The rotating plate 23 is rotatably mounted on the running start fixing plate 1, which facilitates the installation, replacement and angle adjustment of the foot pedal 16.

[0036] In one embodiment, for the aforementioned running start fixing plate 1, both running start fixing plates 1 are fixedly installed with anti-slip plates 24 and rivets 25 at their bottoms. Several rivets 25 are provided. The anti-slip plates 24 are made of rubber and have anti-slip textures on their bottom surfaces. The rivets 25 are evenly distributed in a matrix at the four corners of the bottom of the running start fixing plate 1 to enhance the fixing effect between the running start fixing plate 1 and the ground and prevent the equipment from moving during use.

[0037] In one embodiment, for the aforementioned running start fixing plate 1, a suction cup 26 is fixedly installed at the bottom of the running start fixing plate 1. Several suction cups 26 are provided. The suction cups 26 have good sealing performance and are made of rubber material. When the athlete steps on the foot pedal 16, the suction cups 26 are forcefully suctioned to the ground, further enhancing the stability of the running start device.

[0038] The working principle of the track and field training approach device proposed in this invention is as follows: In the initial state, the two approach fixing plates 1 are in relatively fixed positions, the sliding block 2 is located in a specific position in the second slide groove 14 opened in the approach fixing plate 1, the sliding rod 7 is in the first slide groove 4, the return spring 10 is naturally extended, the electromagnetic sensor 6 is not in the electromagnetic induction groove 5, the air pump 8 is turned off, the foot pedal 16 is adhered to the rotating plate 23 by high viscosity pressure-sensitive adhesive, the rotating plate 23 is rotatably installed on the approach fixing plate 1, and the anti-slip plate 24, rivets 25 and suction cups 26 at the bottom of the two approach fixing plates 1 are in a relatively stable contact state with the ground. The rivets 25 are evenly distributed in a matrix at the four corners of the bottom of the approach fixing plate 1, and the suction cups 26 have good sealing performance.

[0039] If the distance between the two running start plates 1 needs to be adjusted according to the different runners' running needs or the field conditions, the worm 22 installed on one of the running start plates 1 is rotated. Since the worm 22 meshes with the worm wheel 21 fixedly installed on the threaded cylinder 18, the rotation of the worm 22 will drive the worm wheel 21 to rotate, which in turn will drive the threaded cylinder 18 to rotate. One end of the second threaded rod 19 is threadedly connected to the inside of the threaded cylinder 18, and the other end of the second threaded rod 19 is rotatably installed on the other running start plate 1. During the rotation of the threaded cylinder 18, the second threaded rod 19 will move linearly along the threaded cylinder 18. At the same time, the telescopic rod 20 fixedly installed between the two running start plates 1 plays an auxiliary support and guiding role, ensuring that the two running start plates 1 move closer or further apart smoothly, thereby realizing the adjustment of the distance between the two running start plates 1.

[0040] When athletes are ready to use the equipment, they can adjust the angle of the foot pedal 16 by rotating the rotating plate 23 according to their own habits. After adjustment, the rotating plate 23 is mounted on the running start fixing plate 1, which can keep the angle of the foot pedal 16 stable.

[0041] When the athlete steps on the foot pedal 16, the foot pedal 16 is forced to move the foot pedal base 9, which in turn causes the sliding rod 7, which is fixedly connected to it, to slide within the first sliding groove 4. Simultaneously, the rubber anti-slip plates 24 with anti-slip textures on the bottom of the two running approach plates 1 increase friction with the ground, while the matrix-distributed rivets 25 further enhance the fixation to the ground. The rubber suction cups 26, with their excellent sealing properties, are forcefully adhered to the ground, further enhancing the stability of the running approach equipment and preventing it from moving during use.

[0042] As the sliding rod 7 slides, the electromagnetic sensor 6, which is fixedly installed on the sliding rod 7, enters the electromagnetic induction groove 5 set inside the first sliding groove 4. The two are electrically connected. After sensing this change, the electromagnetic sensor 6 sends a signal to control the air pump 8 to start. After the air pump 8 starts, it draws in air through the air inlet pipe 13, which is fixedly connected to one end.

[0043] After the athlete runs, the pressure on the foot pedal 16 disappears. At this time, one end of the return spring 10 is fixed to the sliding rod 7, and the other end is fixed to the first slide groove 4. Under the elastic action of the return spring 10, the return spring 10 restores its deformation and pushes the sliding rod 7 to slide back to its initial position in the first slide groove 4. At this time, the electromagnetic sensor 6 leaves the electromagnetic induction groove 5, the air pump 8 stops sucking in air and starts venting air. The two ends of the air pump 8 are connected to the exhaust holes 12 evenly distributed on both sides of the foot pedal base 9 through the air supply pipe 11. The air discharged by the air pump 8 is sprayed out from the exhaust holes 12 through the air supply pipe 11 to clean the dust on the surface of the foot pedal 16.

[0044] If the foot pedal 16 wears out due to long-term use or needs to be replaced with a different specification, it can be easily removed from the rotating plate 23 using high-viscosity pressure-sensitive adhesive for replacement. Afterwards, the equipment is restored to its initial state and ready for the next use.
