Description

Technical Field

[0001] This invention relates to the field of sports training equipment technology, and in particular to an athletics arm swing posture correction trainer that simulates a push-pull resistance environment. Background Technology

[0002] In track and field, the correctness of arm swing posture directly affects running efficiency and the risk of sports injuries. This is especially true for sprints, middle-distance and long-distance running, which require athletes to maintain relaxed shoulder joints, moderate elbow flexion and extension, and arm swings that do not cross the body's midline during high-speed movement. However, in actual training, athletes are prone to incorrect postures such as arm abduction, adduction, excessive or insufficient swing amplitude. Prolonged incorrect arm swing not only reduces athletic performance but can also lead to problems such as rotator cuff injuries and lower back compensation.

[0003] Currently, the most common track and field arm swing training equipment on the market mainly includes handheld dumbbells, resistance bands, or fixed arm swing training racks. Handheld dumbbells can only provide a unidirectional gravitational load and cannot simulate the bidirectional pushing and pulling resistance environment during the arm swing process. Furthermore, athletes cannot receive immediate feedback when their posture deteriorates due to fatigue. While resistance bands can provide some tensile resistance, they are usually only connected to the wrist and a certain part of the body, making it difficult to simultaneously constrain hand posture and lacking detection and alarm functions for postural errors. Fixed arm swing training racks are bulky, inconvenient to carry, and cannot adjust the resistance and trigger sensitivity according to individual athlete differences.

[0004] In summary, existing technologies lack an integrated training device capable of simultaneously simulating both push and pull resistance, actively correcting arm swing posture, and providing immediate audible and visual alarms for incorrect postures. This limits training effectiveness and makes it difficult to correct erroneous movements in a timely manner. Therefore, an athletics arm swing posture correction training device that simulates a push-pull resistance environment is needed to address these issues. Summary of the Invention

[0005] The purpose of this invention is to solve the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An athletics arm swing posture correction trainer simulating a push-pull resistance environment includes: A corrective gripping component includes a corrective gripping rod for gripping, the surface of the corrective gripping rod is provided with a gripping area, a thumb restraint sleeve for restraining the thumb is provided above the right gripping area of ​​the corrective gripping rod, and a power supply battery module is provided on the front of the bottom end of the corrective gripping rod.

The column housing has a cavity for the movable plate to move, and a power contact post that contacts and energizes the electrode plate is located at the top of the cavity. The top of the movable plate is connected to the top of the inner wall of the column housing cavity through a return spring. A buzzer is built into the buzzer column, and a silicone block is located at the bottom of the buzzer column. A warning light strip is installed on the surface of the silicone block through an annular groove. The battery module is electrically connected to the electrode plate, the power contact post, the buzzer, and the warning light.

[0007] Preferably, the left side of the grip area of ​​the corrective grip bar is also provided with an auxiliary fixing part for conforming to the athlete's hand, the auxiliary fixing part including a guard bar that is connected and fixed to the corrective grip bar; The left side of the guard rod is fitted with a threaded shaft through a threaded hole, and a knob is connected to the left side of the threaded shaft. The right side of the threaded shaft is fitted with an inner shaft through a through hole, and a rubber limiting plate is provided on the right side of the inner shaft. The right side of the rubber limiting plate has a limiting groove adapted to a finger. The inner shaft and the inner wall of the through hole of the threaded shaft are connected and fixed by a support spring.

[0008] Preferably, the elastic element includes two parallel resistance-increasing elastic bands, both ends of which are connected and fixed to the locking block, and the locking block has an H-shaped cross-section.

[0009] Preferably, both of the fasteners include an outer plate, and the surfaces of the two outer plates are provided with a plurality of slots for engaging with the fastener block. The slot on the left side of the outer plate faces downward and the slot on the right side faces upward. A fixing ring A is connected to the outer side of both outer plates. One of the fixing rings A is hooked and connected to the right end of the thumb restraint sleeve, and the other fixing ring A is hooked and connected to the fixing ring B.

[0010] Preferably, a pressure plate is fastened to the slot opening of the external plate, and the vertical cross-section of the pressure plate is L-shaped. The vertical end of the pressure plate is fixed to the external plate by locking screws.

[0011] Preferably, the elastic armband has a plurality of rubber ribs built inside to prevent the elastic armband from curling or folding, and the elastic armband is provided with elastic sealing strips at the top and bottom to seal the edges of the elastic armband and the rubber ribs.

[0012] Preferably, the elastic armband surface is sewn with a tightening tension band, and the inner wall of the tightening tension band is provided with a napped fabric, and the elastic armband surface is provided with a hook-and-loop fabric that is hooked to the napped fabric.

The corrective grip bar, together with the thumb restraint sleeve, can fix the thumb orientation, so that the palm always maintains the correct posture of facing the body's midline during the arm swing; the auxiliary fixing part uses an adjustable rubber limit plate to hold against the middle finger, ring finger, etc., and uses a support spring to provide elastic cushioning, further fixing the hand position and avoiding fatigue and slippage caused by prolonged gripping, thereby reducing the probability of incorrect arm swing posture from the source.

[0016] 2. This invention simulates a bidirectional push-pull resistance environment during arm swing by connecting the elastic component and the arm ring component in series. The elastic component generates tensile resistance and retraction resistance respectively when the arm swings back and forth, and the resistance can be linearly adjusted by setting multiple resistance-increasing elastic bands in parallel to meet the strength growth needs of different training stages. The arm ring component, through a multiple fixing structure of elastic armband, rubber bands and tightening tension band, ensures the stability of resistance transmission and wearing comfort, effectively exercising the muscles around the shoulder joint.

[0017] 3. This invention achieves instant audible and visual feedback for incorrect arm swing posture through a mechanical touch-triggered structure at the warning point. When an incorrect arm swing posture causes the silicone block to collide with the body, the buzzer column moves upward to push the electrode plate and the connecting column to conduct electricity, the buzzer emits a single-tone alarm, and the warning light strip flashes, reminding the athlete to actively correct their posture. The reset spring ensures that the alarm automatically stops after the posture is corrected. The purely mechanical triggering structure does not require complex sensors, has high reliability and low cost, and can be adapted to athletes of different body types through the threaded adjustment of the column chamber and the corrective grip rod, avoiding false alarms or missed alarms.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0022] The following is a characteristic connection structure of the overall scheme; Reference Figure 1-8 An athletics arm swing posture correction trainer simulating a push-pull resistance environment, comprising: The corrective grip 1 includes a corrective grip rod 11 for gripping, a gripping area is provided on the surface of the corrective grip rod 11, a thumb restraint sleeve 12 for restraining the thumb is provided above the right gripping area of ​​the corrective grip rod 11, and a power supply battery module 13 is provided on the front of the bottom end of the corrective grip rod 11. Warning section 2 includes a column housing 21 fixedly connected to the bottom end of the corrective grip rod 11. A buzzer column 22 is inserted into the bottom end of the column housing 21, and a movable plate 25 is connected to the top end of the buzzer column 22. An electrode plate 26 is connected to the top end of the movable plate 25. The column housing 21 has a cavity for the movable plate 25 to move, and a power contact post 27 that contacts and energizes the electrode plate 26 is located at the top end of the cavity. The top end of the movable plate 25 is connected to the top end of the cavity wall of the column housing 21 via a return spring 28. A buzzer is built into the buzzer column 22, and a silicone block 23 is located at the bottom end of the buzzer column 22. A warning light strip 24 is installed on the surface of the silicone block 23 through an annular groove. The trainee can grip the corrective grip rod 11 and insert their thumb into the thumb restraint sleeve 12 to ensure the correct posture when swinging the arm. When incorrect arm swing posture during training causes the corrective grip bar 11 to tilt, the warning part 2 at the bottom of the corrective grip bar 11 comes into contact with the trainee's body, causing the silicone block 23 to hit the body. The silicone block 23 pushes the buzzer column 22 to push the movable plate 25, which in turn pushes the electrode plate 26 to make contact with the electrical terminal 27, generating a trigger signal. At this time, the buzzer inside the buzzer column 22 produces a single-tone adjustment alarm, and the warning light strip 24 flashes a warning, realizing an audible and visual alarm to prompt the trainee to correct the posture. In conjunction with the spring-loaded part 4 and the arm ring part 5, it can effectively reduce the probability of incorrect posture and effectively achieve the training correction effect. At the same time, by increasing the number of elastic parts 42, the pushing and pulling resistance can be simulated to achieve a better training effect. The bullet-resistant part 4 includes an elastic member 42 with elastic tension and a buckle member 41 disposed on both sides of the elastic member 42. The left side of the elastic member 42 is hooked and connected to the thumb restraint sleeve 12 through the buckle member 41. The arm ring part 5 includes an elastic armband 52 for attaching and fixing to the arm of a person, and a fixing ring B51 is connected to the left side of the elastic armband 52. The fixing ring B51 is hooked and connected to the elastic element 42 through another buckle 41.

[0023] The left side of the grip area of ​​the corrective grip bar 11 is also provided with an auxiliary fixing part 3 that fits the athlete's hand. The auxiliary fixing part 3 includes a guard bar 31 that is connected and fixed to the corrective grip bar 11.

[0024] A threaded shaft 32 is inserted into the left side of the guard rod 31 through a threaded hole, and a knob 35 is connected to the left side of the threaded shaft 32. An inner shaft 33 is inserted into the right side of the threaded shaft 32 through a through hole, and a rubber limiting plate 34 is provided on the right side of the inner shaft 33. A limiting groove adapted to a finger is opened on the right side of the rubber limiting plate 34. The inner shaft 33 and the inner wall of the through hole of the threaded shaft 32 are connected and fixed by a support spring 36.

[0025] The elastic element 42 includes two parallel resistance-increasing elastic bands 421, both ends of which are connected and fixed to the locking block 422. The locking block 422 has an H-shaped cross-section.

[0026] Both fasteners 41 include an outer plate 411. The surfaces of the two outer plates 411 have several slots that engage with the locking block 422. The slot on the left outer plate 411 faces downward, and the slot on the right outer plate 411 faces upward. Both openings serve to prevent the plate from slipping off. Both outer plates 411 are connected to a fixing ring A412 on their outer sides. One fixing ring A412 is hooked and connected to the right end of the thumb restraint sleeve 12, and the other fixing ring A412 is hooked and connected to the fixing ring B51.

[0027] A pressure plate 413 is fastened to the slot opening of the external board 411, and the vertical section of the pressure plate 413 is L-shaped. The vertical end of the pressure plate 413 is fixed to the external board 411 by a locking screw 414.

[0028] The elastic armband 52 has several rubber ribs 53 built inside to prevent the elastic armband 52 from curling or folding, and elastic sealing strips 54 are provided on the top and bottom of the elastic armband 52 to seal the edges of the elastic armband 52 and the rubber ribs 53.

[0029] The elastic armband 52 has a tightening tension band 56 sewn onto its surface, and the inner wall of the tightening tension band 56 is provided with a fleece fabric 57. The elastic armband 52 has a hook-and-loop fabric 55 that is hooked and fastened to the fleece fabric 57.

[0030] A rubber guard plate 14 for protecting the forearm is fixed to the bottom right side of the thumb restraint sleeve 12 by bolts. The right side of the rubber guard plate 14 is curved upwards, and two silicone plates for positioning are provided at the bottom of the rubber guard plate 14.

[0031] The following detailed descriptions of various scenarios through multiple embodiments are provided to facilitate understanding; Example 1; This embodiment provides a complete track and field arm swing posture correction trainer that simulates the push and pull resistance environment. It is suitable for track and field athletes to correct incorrect postures during daily arm swing training, and at the same time simulate the push and pull resistance environment during arm swing to improve specific muscle strength.

[0032] Use case settings: Taking a track and field athlete performing stationary arm swing training as an example, the athlete needs to wear the training device on the right arm, or it can be used on both hands. In this embodiment, the right hand is used as an example. During the continuous arm swing process of about 5-10 minutes, the training device can detect whether the arm tilt angle exceeds the standard in real time, and issue an audible and visual alarm when it exceeds the standard. At the same time, the adjustable resistance simulates the feeling of pushing or pulling against the wind or under load when swinging the arm.

[0033] Structural connections and fit relationships: First, the athlete secures the arm loop 5 to the upper arm near the shoulder joint. Specifically, the elastic armband 52 wraps around the upper arm, with internal rubber ribs 53 providing anti-rolling support, and elastic sealing strips 54 on the upper and lower sides ensuring a snug fit without digging into the skin; By tightening the tension band 56, the inner wall of the fabric 57 is fastened to the hook and loop fabric 55 on the surface of the elastic armband 52, thereby securely fitting the entire armband 5 onto the arm. A fixing ring B51 is connected to the left side of the elastic armband 52.

[0034] Then, the athlete holds the corrective grip 1, opens the tiger's mouth of the right hand, and naturally holds the grip area of ​​the corrective grip bar 11 with the four fingers. The thumb is inserted into the thumb restraint sleeve 12, which restrains the direction of the thumb, thereby forcing the palm to maintain the correct posture of the palm facing the body center line during the arm swing. At the same time, the athlete connects the ballistic blocking part 4 with the left hand or an assistant. The buckle 41 on the left side of the elastic component 42 is hooked and connected to the right ring end of the thumb restraint sleeve 12, and the other buckle 41 on the right side of the elastic component 42 is hooked and connected to the fixing ring B51. Thus, the corrective grip 1, the elastic resistance part 4, and the arm ring part 5 are connected in series to form an elastic resistance circuit.

[0035] Work process: After the arm swing training begins, the athlete swings his arm in a forward and backward direction. First, when the arm swings forward, the elastic element 42 is stretched, generating backward resistance, simulating the "pull" resistance in a push-pull environment. When the arm swings backward, the elastic element 42 retracts, generating forward resistance, simulating "pushing" resistance. The athlete needs to overcome this resistance to complete the arm swing, thereby effectively exercising the muscles around the shoulder joint.

[0036] Furthermore, during the arm swing, the warning part 2 at the bottom of the corrective grip bar 11 is always close to the side of the athlete's torso.

[0037] If the athlete's arm swing posture is correct, the angle between the arm and the torso is moderate, and the arm is neither adducted nor abducted, then the silicone block 23 of the warning part 2 will maintain a small gap with the body or will not cause significant collision. If an athlete adopts an incorrect posture, such as excessive arm abduction causing the corrective grip bar 11 to tilt outward, or excessive arm adduction causing the corrective grip bar 11 to tilt to the side of the body, the silicone block 23 will collide with the torso or hip. Subsequently, the impact force will push the buzzer column 22 to move upward along the axis of the column chamber 21, and the movable plate 25 will compress the return spring 28 upward until the electrode plate 26 at the top of the movable plate 25 contacts and conducts electricity with the terminal post 27 at the top of the cavity.

[0038] Finally, the electrical energy provided by the battery module 13 is transmitted through the electrode plate 26 and the power terminal 27 to the buzzer built into the buzzer column 22 and the warning light strip 24 on the surface of the silicone block 23. The buzzer emits a single-tone alarm and the warning light strip 24 flashes, realizing a dual warning of sound and light.

[0039] After hearing or seeing the alarm, the athlete immediately corrects their arm swing posture. When the posture returns to normal and the silicone block 23 is no longer under pressure, the reset spring 28 pushes the movable plate 25 and the buzzer column 22 to reset, the electrode plate 26 disconnects from the power terminal 27, and the alarm stops.

[0040] The battery module 13 located on the front of the bottom end of the correction grip 11 is connected to the power terminal 27 in the column compartment 21 and the buzzer and warning light strip 24 in the buzzer column 22 via internal wires, forming a normally open circuit that closes only when the electrode plate 26 contacts the power terminal 27.

[0041] The reset spring 28 is sleeved on the outside of the electrical contact post 27. One end of the spring is fixed to the top of the inner wall of the column chamber 21, and the other end is fixed to the top of the movable plate 25, so as to ensure that the electrode plate 26 and the electrical contact post 27 remain disconnected when not under force.

[0042] The rubber guard plate 14, which is fixed to the right side of the bottom end of the thumb restraint sleeve 12 by bolts, extends downward and bends to the right. The two silicone plates at the bottom end fit against the back of the athlete's forearm to prevent the forearm from being scratched by the hard edge of the thumb restraint sleeve 12 when swinging the bar.

[0043] The auxiliary fixing part 3 is also installed in this embodiment as an optional auxiliary structure. The guard rod 31 is fixedly connected to the corrective grip rod 11. The athlete can rotate the knob 35 to adjust the extension length of the threaded shaft 32 so that the limiting groove of the rubber limiting plate 34 abuts against the middle finger and ring finger. The support spring 36 provides elastic cushioning, thereby further fixing the hand position and avoiding grip fatigue.

[0044] Combined effects: By combining the corrective grip component 1 and the auxiliary fixing part 3, the correct posture of the hand and thumb is ensured; through the connection of the elastic resistance part 4 and the arm ring part 5, elastic resistance is directly transmitted between the arm and the grip component, simulating a push-pull environment; and through the mechanical touch triggering of the warning part 2, an audible and visual alarm is provided, achieving immediate feedback on incorrect posture. The three working together enable athletes to autonomously correct their arm swing trajectory while receiving resistance training, greatly improving training efficiency.

[0045] Example 2; Based on Embodiment 1, this embodiment focuses on describing the expandable structure of the elastic element 42 and its resistance adjustment method, while the rest of the structure is the same as in Embodiment 1.

[0046] Scene setting: After a period of training, the basic resistance is no longer sufficient to meet the needs of strength growth, and it is necessary to increase the pushing and pulling resistance to further enhance explosive power.

[0047] Structural fit and process: In this embodiment, the elastic element 42 is composed of two parallel friction-increasing elastic bands 421. Both ends of each friction-increasing elastic band 421 are fixedly connected to the H-shaped cross-section locking block 422. The locking element 41 includes an outer plate 411. The surface of the outer plate 411 has multiple slots. The slot opening of the left locking element 41 faces downward, and the slot opening of the right locking element 41 faces upward. This opposite orientation design makes the locking block 422 tighter and tighter during the extension of the swing arm, and it will not come out.

[0048] The process of increasing resistance: Athletes can take one or more spare resistance bands 421 and their locking blocks 422. First, insert the left locking block 422 from top to bottom into the slot with the opening facing down on the left outer plate 411, and at the same time insert the right locking block 422 from bottom to top into the slot with the opening facing up on the right outer plate 411. Next, fasten the pressure plate 413 to the slot opening, so that the L-shaped vertical plate of the pressure plate 413 covers the exposed part of the card block 422, and then tighten the locking screw 414 to fix the pressure plate 413 to the outer plate 411. Finally, when the athlete swings their arms, two or more sets of resistance bands 421 participate in the stretching simultaneously, and the total resistance increases exponentially.

[0049] The resistance-increasing elastic band 421 is made of highly elastic rubber or latex material, and its original length is equal to ensure uniform force when connected in parallel. The H-shaped structure of the locking block 422 can ensure that it slides stably in the slot without flipping. The pressure plate 413 and the locking screw 414 play a safety locking role to prevent the locking block 422 from accidentally coming off during violent movements.

[0050] This embodiment allows athletes to easily increase or decrease the number of resistance bands 421 according to their own strength level or training stage, thereby achieving linear adjustment of resistance. Compared with replacing the entire elastic component 42, this parallel plug-in structure has lower cost and more intuitive operation, and the parallel arrangement of the two bands ensures the consistency of the stretching direction and the balance of force.

[0051] Example 3; Based on Example 1, this embodiment optimizes the description of the trigger sensitivity adjustment and anti-accidental touch structure of the warning part 2, while the rest of the structure remains the same.

[0052] Scenario setting: For athletes of different body types, the natural gap between the arm and the torso is different when swinging the arm. Athletes with a thinner body type may need a higher trigger sensitivity, that is, a smaller tilt angle is enough to trigger the trigger, while athletes with a stronger body type may need to reduce the sensitivity to avoid frequent false alarms.

[0053] Structural fit and process: In this embodiment, the connection between the column chamber 21 and the bottom end of the corrective grip rod 11 is designed as a fine-tunable structure, i.e., a threaded connection. For example, the top of the column chamber 21 is provided with an external thread, and the bottom end of the corrective grip rod 11 is provided with an internal thread adjustment seat. First, the athlete performs a self-test before training: stand naturally and maintain the correct arm swing posture, observe the distance between the silicone block 23 and the side of the body. If the distance is too small, it is easy to trigger it accidentally. Then rotate the column chamber 21 so that it moves outward relative to the corrective grip rod 11, i.e. away from the body, to increase the initial gap. If the distance is too large and triggers only when the posture is seriously incorrect, then rotate the column chamber 21 in the opposite direction to reduce the initial gap.

[0054] Secondly, during the training process, when the silicone block 23 is bumped, the buzzer column 22 pushes the movable disk 25 upward, and the electrode plate 26 contacts the power receiving column 27. In this embodiment, the top of the power receiving column 27 is provided with a conical contact, and the electrode plate 26 is an elastic metal sheet. When the two are in contact, there is a slight interference to ensure the reliability at the moment of power-on.

[0055] Finally, after the alarm is cleared, the spring force of the reset spring 28 needs to be sufficient to overcome the weight of the buzzer column 22 and the silicone block 23 as well as the friction of the movable plate 25, to ensure rapid reset and avoid continuous false alarms.

[0056] The silicone block 23 is made of flexible silicone material. The warning light strip 24, which is installed on the surface through a ring groove, is embedded inside the silicone block 23. This does not affect the cushioning of impacts, but also provides 360-degree visible flashing light. The buzzer inside the buzzer column 22 uses a piezoelectric buzzer plate, which has low power consumption.

[0057] In this embodiment, by adjusting the extension length of the column chamber 21, the alarm trigger threshold can be adapted to athletes of different body types, reducing unnecessary alarm interference. At the same time, the cooperation between the elastic electrode sheet 26 and the conical contact improves the reliability of power supply, and the cushioning design of the silicone block 23 avoids bumps and pain, improving wearing comfort.

[0058] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
