Description

Technical Field

[0001] This invention relates to the field of fitness equipment, and more particularly to a type of sports equipment that can prevent muscle strain. Background Technology

[0002] Chinese patent application number CN202223017866.2 describes a rowing machine that facilitates self-checking of posture. It uses a monitor to track the athlete's sides and transmits the images to a display screen, allowing the athlete to check their posture for accuracy. This avoids joint injuries caused by incorrect training posture. However, this device relies solely on the monitor, meaning the athlete can only identify and correct significant posture errors, not minor or incorrect force application. Furthermore, with prolonged use, the rowing rope wears down. When it breaks, the athlete is thrown backward and falls, potentially resulting in serious injuries and harming their health. Summary of the Invention

[0003] To overcome the shortcomings of existing rowing machines, which rely solely on monitors to track exercisers and can only correct major postural errors, but cannot provide subtle corrections for minor postural errors or incorrect force application, such as hunching over or knees buckling inward, which can cause varying degrees of injury to exercisers, and the fact that the ropes wear down over time and can break during use, causing the exerciser to fall backward and tilt, resulting in serious muscle strains and harming their health, this invention provides a sports equipment that can prevent muscle strains.

[0004] The technical solution is as follows:

[0005] A type of sports equipment that can prevent muscle strains includes a rowing machine and components connected to the rowing machine:

[0006] A seat that can be moved on the rowing machine and is used for exercisers to sit on;

[0007] The water tank is used at one end of the rowing machine to adjust water resistance.

[0008] Corrective components, which are installed on the seat, are used to correct the exerciser's posture and prevent injury;

[0009] A safety system surrounds the seat to prevent exercisers from falling off the rowing machine.

[0010] Its further features are:

[0011] The seat is equipped with a backrest, a neck pillow, and a backrest cushion.

[0012] The corrective components include: a first corrective block, which is disposed on the open side of the seat and is used to protect the exerciser's meniscus cartilage; a second corrective block, several of which are fixed to the backrest to prevent the exerciser from experiencing neck soreness after exercise; and shoulder straps, at least two of which are fixed to the backrest to prevent the exerciser from leaning forward.

[0013] The first corrective block is set as an inverted isosceles trapezoid, and the second corrective block is set as an inverted right trapezoid, so as to better fit the protected position.

[0014] The protection system includes: a first barrier located at the right end of the rowing machine to prevent the exerciser from falling off the machine; a shock absorber connected to the first barrier to reduce the impact force of the exerciser moving backward; and a return mechanism located between the seat and backrest to correct and return to its original position under the action of a spring.

[0015] The return structure comprises a rotating shaft, gears, friction blocks, and a pressing block. The rotating shaft is rotatably connected to the inside of the backrest, and several springs are movably connected to the rotating shaft. Gears are fixed to the rotating shaft. Friction blocks that move up and down to slow down the tilting speed of the backrest are slidably connected to the inside of the seat. A pressing block that compresses the friction block to move upwards to slow down the tilting speed of the backrest is fixed to the right side of the backrest.

[0016] The friction block is equipped with several friction plates, which are made of a deformable material.

[0017] An elastic rope is fixedly connected to the extrusion block, and the other end of the elastic rope is fixedly connected to the water tank.

[0018] The protection system also includes a second barrier and a protective block; the second barrier and the protective block are located on both sides of the rowing machine and connected to the first barrier, to prevent the exerciser from falling to the left or right and getting injured.

[0019] The protective block is made of a deformable material, and the second enclosure can rotate relative to the first enclosure.

[0020] A type of sports equipment that can prevent muscle strains includes a rowing machine and components connected to the rowing machine:

[0021] A seat that can be moved on the rowing machine and is used for exercisers to sit on;

[0022] The water tank is used at one end of the rowing machine to adjust water resistance.

[0023] Corrective components, which are installed on the seat, are used to correct the exerciser's posture and prevent injury;

[0024] A safety system designed to prevent users from falling off a rowing machine. This invention offers the following advantages: During rowing machine use, the backrest allows users to maintain an upright posture with their chest out and back straight, preventing lower back muscle strain and protecting their health.

[0025] During the use of the rowing machine, the first corrective block keeps the exerciser's legs apart during the exercise, preventing knee valgus and damage to the meniscus cartilage.

[0026] During the use of the rowing machine, the first corrective block prevents the exerciser from shrugging their shoulders and avoids neck soreness after exercise.

[0027] In the process of the rope breaking and causing the exerciser to move backward and fall quickly, the first barrier protects the exerciser and prevents the exerciser from falling directly out of the rowing machine and getting injured.

[0028] In the process of the exerciser moving backward and falling rapidly due to the rope breaking, the shock absorber slows down the speed of the exerciser's backward movement to prevent the exerciser from being injured by rapidly hitting the first barrier.

[0029] The squeezing block presses the friction block to move it upwards, and then the friction generated when the friction block contacts the gear slows down the speed at which the backrest tilts backward, further preventing the exerciser from being injured by a rapid impact on the first barrier.

[0030] The gears drive the friction plates to tilt to the left, causing several friction plates to stack from right to left, increasing the contact area between the friction plates and the gears, further slowing down the speed at which the backrest tilts backward. At the same time, after the friction plates are compressed and deformed, the bottom of the friction plates hardens, increasing the friction force and causing the gears to jam, thereby stopping the backrest from tilting backward and preventing the exerciser's head from directly hitting the rowing machine due to excessive tilting angle.

[0031] When the exerciser moves backward too quickly, the elastic rope pulls the squeezing block to rotate, which in turn squeezes the friction block to move it upward. Then, the friction generated when the friction block contacts the gear slows down the speed at which the backrest tilts backward, further improving the protective effect of the safety system on the exerciser.

[0032] As the exerciser tilts to the left or right, the protective blocks intercept the tilting exerciser, preventing the exerciser from falling directly off the rowing machine and causing injury, thus further ensuring the personal safety of the exerciser during the exercise process.

[0042] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0043] like Figures 1-8 As shown, the sports equipment for preventing muscle strain in this embodiment includes a rowing machine 1 and a seat 2, a water tank 1001, a correction component, and a protection system connected to the rowing machine 1.

[0044] Water tank 1001 is located at one end of rowing machine 1 and is used to adjust water resistance, simulating the resistance of rowing in water and improving the rowing experience.

[0045] like Figures 1-3As shown, the seat 2 can be moved along the direction of movement of the rowing machine 1 via rollers and is used for the exerciser to sit on.

[0046] The seat 2 is equipped with a backrest 3; the backrest 3 is equipped with a neck pillow 4; and the backrest 3 is equipped with a bolster 5. During the use of the rowing machine 1, the backrest 3 helps the exerciser maintain an upright posture, preventing lower back muscle strain. The neck pillow 4 protects the exerciser's neck, preventing neck injury during rapid backward leaning. The bolster 5 protects the exerciser's lower back, preventing lower back injury during rapid backward leaning, thus ensuring the exerciser's safety. The seat 2 is also equipped with a correction component; during the use of the rowing machine 1, the correction component corrects the exerciser's posture, preventing injury due to incorrect posture. The rowing machine 1 is equipped with a safety system; in the event of a rope breakage causing the exerciser to move rapidly backward and tilt, the safety system cushions the fall, preventing the exerciser from being injured by falling off the rowing machine 1, further ensuring the exerciser's safety.

[0047] The correction component, which is installed on the seat 2, is used to correct the exerciser's posture and prevent injury; the correction component includes: a first correction block 101, which is installed on the open side of the seat 2 and is used to protect the exerciser's meniscus cartilage; a second correction block 102, several of which are fixed to the backrest 3 to prevent the exerciser from experiencing neck soreness after exercise; and shoulder straps 103, at least two of which are fixed to the backrest 3 to prevent the exerciser from leaning forward.

[0048] The first correction block 101 is set as an inverted isosceles trapezoid, and the second correction block 102 is set as an inverted right-angled trapezoid, so as to better fit the protected position.

[0049] The return structure consists of a rotating shaft 203, a gear 204, a friction block 205, and a pressing block 206. The rotating shaft 203 is rotatably connected to the inside of the backrest 3. Several springs are movably connected to the rotating shaft 203. The gear 204 is fixedly connected to the rotating shaft 203. The friction block 205, which moves up and down to slow down the tilting speed of the backrest 3, is slidably connected to the inside of the seat 2. The pressing block 206, which presses the friction block 205 to move it upward to slow down the tilting speed of the backrest 3, is fixedly connected to the right side of the backrest 3.

[0050] Several friction plates 207 are installed on the friction block 205. The friction plates 207 are made of deformable material.

[0051] An elastic rope 208 is fixedly connected to the extrusion block 206, and the other end of the elastic rope 208 is fixedly connected to the water tank 1001.

[0052] The correction component includes a first correction block 101; the first correction block 101 is installed on the left side of the seat 2, and the first correction block 101 is set as an inverted isosceles trapezoid; during the use of the rowing machine 1, the first correction block 101 is located on the side where the exerciser's legs are facing each other, and the first correction block 101 holds the exerciser's legs apart during the exercise, so as to avoid knee valgus and damage to the meniscus cartilage.

[0053] The correction component also includes a second correction block 102; two symmetrical second correction blocks 102 are fixed to the left side of the backrest 3, and the second correction blocks 102 are set as inverted right-angled trapezoids; during the use of the rowing machine 1, the second correction blocks 102 are always located above the exerciser's shoulders, and the second correction blocks 102 hold the exerciser's shoulders to prevent the exerciser from shrugging his shoulders during exercise and avoid neck soreness after exercise.

[0054] It also includes shoulder straps 103; two symmetrical shoulder straps 103 are fixed to the left side of the backrest 3; during the rope rebound process, the shoulder straps 103 prevent the exerciser from leaning forward.

[0055] like Figures 4-7 As shown, the protection system in this embodiment surrounds the seat 2 and is used to prevent the exerciser from falling out of the rowing machine 1. The protection system includes: a first barrier 201, which is located at the right end of the rowing machine 1 to prevent the exerciser from falling out of the rowing machine 1; a buffer 202, which is connected to the first barrier 201 to reduce the impact force of the exerciser moving backward; and a return structure, which is disposed between the seat 2 and the backrest 3 and is corrected and returned to its original position under the action of a spring.

[0056] The first barrier 201 can protect the exerciser from falling directly off the rowing machine 1 and getting injured when the rope breaks and the exerciser moves backward and tilts over quickly.

[0057] A buffer 202 is fixedly connected to the rowing machine 1; when the rope breaks, during the process of the exerciser moving backward and falling over quickly, the buffer 202 slows down the speed of the exerciser's backward movement and prevents the exerciser from being injured by rapidly hitting the first barrier 201.

[0058] The protection system also includes a return structure, which comprises a pivot 203, a gear 204, a friction block 205, and a compression block 206. The pivot 203 is rotatably connected to the inner side of the backrest 3, and two symmetrically wound springs are hinged to the pivot 203. A gear 204 is fixedly connected to the pivot 203. The friction block 205 is slidably connected to the inner side of the seat 2. A compression block 206 is fixedly connected to the right side of the backrest 3. In the event of a rope breakage causing the exerciser to move rapidly backward and tilt, the pressure generated by the tilting motion, viewed from front to back, compresses the backrest 3, causing it to rotate around the pivot 203. 03 rotates clockwise around the center of rotation, which in turn drives gear 204 to rotate clockwise synchronously. At the same time, the backrest 3 drives the compression block 206 to rotate clockwise synchronously. The compression block 206 then inserts under the friction block 205, causing it to move upward along the surface of the compression block 206. The friction generated when the friction block 205 contacts the gear 204 slows down the backward tilting speed of the backrest 3, further preventing the exerciser from being injured by a rapid impact on the first barrier 201. After the protection system finishes working, the backrest 3 is returned to its original position by a spring, providing a second cushioning protection.

[0059] It also includes friction plates 207; several friction plates 207 are installed on the friction block 205, and the friction plates 207 are made of deformable material; during the operation of the friction block 205, the friction plates 207 are tilted to the left by the gear 204, so that several friction plates 207 are stacked from right to left, increasing the contact area between the friction plates 207 and the gear 204, further slowing down the speed at which the backrest 3 tilts backward. At the same time, after the friction plates 207 are compressed and deformed, the bottom of the friction plates 207 hardens, the friction increases, and the gear 204 is locked, thereby stopping the backrest 3 from tilting backward, preventing the exerciser's head from directly hitting the rowing machine 1 due to the excessive backward tilt angle of the backrest 3 and causing injury.

[0060] It also includes an elastic rope 208; the elastic rope 208 is fixedly attached to the compression block 206, and the other end of the elastic rope 208 is fixedly attached to the water tank 1001; when the rope breaks, during the process of the exerciser moving backward and tilting, when the exerciser moves backward too fast, the elastic rope 208 pulls the compression block 206 to rotate, thereby squeezing the friction block 205 to move upward, and then the friction generated when the friction block 205 contacts the gear 204 slows down the speed at which the backrest 3 tilts backward, further improving the protective effect of the protection system.

[0061] In such Figure 1 and Figure 8As shown, it also includes a second enclosure 301 and protective blocks 302; two symmetrical second enclosures 301 are fixedly attached to the rowing machine 1; several protective blocks 302 are fixedly attached to each second enclosure 301, and the protective blocks 302 are made of deformable material; adjacent protective blocks 302 are connected by protective ropes; when the exerciser tilts to the left or right, the protective blocks 302 intercept the tilting exerciser, preventing the exerciser from falling directly out of the rowing machine 1 and causing injury, further ensuring the personal safety of the exerciser during the exercise process.

[0062] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
