Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, specifically, to a strength training device. Background Technology

[0002] The deadlift machine is a common piece of fitness equipment primarily used to train the glutes and lower body muscles. Traditional deadlift machines typically use a fixed-height handle design, which to some extent limits the comfort and training effectiveness for users of different heights and body types. Because the handle height is not adjustable, the hips cannot fully open during the deadlift motion, resulting in insufficient stimulation of the gluteal muscles. In this situation, the gluteal muscles can only participate as an auxiliary muscle group, failing to achieve the ideal training effect and thus failing to fully realize the training function of the deadlift machine.

[0003] Therefore, there is an urgent need to develop a strength trainer that provides effective training and is highly adaptable to users. Utility Model Content

[0044] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" 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 between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0045] like Figures 1 to 2 As shown, this utility model provides a strength training device, including: a main frame mechanism, an adjustment mechanism 3, two handle mechanisms 4, and a foot pedal mechanism 5; the main frame mechanism includes a base frame 1 and a stand 2 erected on one end of the base frame 1; the adjustment mechanism 3 is connected to the stand 2 in a manner that allows it to swing up and down relative to the stand 2; the two handle mechanisms 4 are symmetrically arranged on the adjustment mechanism 3 in a manner that allows their height to be adjusted relative to the adjustment mechanism 3; the foot pedal mechanism 5 is connected to the other end of the base frame 1. The two handle mechanisms 4 are positioned on either side of the trainee, standing on the foot pedal mechanism 5.

[0046] In some embodiments, the trainee stands with their feet shoulder-width apart or slightly wider on the foot pedal 5, toes pointing forward, and adjusts the two handle mechanisms 4 to a height suitable for their body condition, such as hip joint position. Specifically, the trainee can adjust the handles using the height adjustment function of the handle mechanisms 4 to a position that allows for full hip opening while maintaining natural arm extension, based on their height, arm length, and range of motion of the hip joint. For example, shorter trainees can lower the handles to make it easier to open the hip joint during deadlifts without excessive arm bending; while taller trainees can raise the handles to avoid excessive shoulder pressure due to overextension of the arms.

[0047] In some embodiments, after adjusting the two handle mechanisms 4 to a height suitable for one's hip joint position, grasp the handle mechanisms 4 on both sides of the body with both hands, arms hanging naturally, back straight, shoulders pulled back, slowly bend the knees and push the hips forward, moving the hips backward and downward, while keeping the arms straight, feeling the stretch in the gluteal muscles. At this time, the hip joint gradually opens, the thighs are parallel to the ground or the squat depth is adjusted according to one's own ability. After squatting to the lowest point, use the strength of the gluteal muscles to slowly straighten the hip joint, and the knees also gradually straighten. At the same time, pull the adjustment mechanism 3 upward from the initial height through the handle mechanisms 4 until the body is fully upright, completing one deadlift exercise. After completing one deadlift exercise, repeat several times according to the training plan to achieve the purpose of exercising the gluteal muscles. The trainee can maintain the correct posture during training, so that the gluteal muscles can be more fully stimulated, thereby improving the training effect and reducing the risk of injury.

[0048] In some embodiments, the foot pedal mechanism 5 includes a pedal surface 51 and a support leg 52.

[0049] Preferably, the strength training device of this utility model further includes a support frame mechanism 6 and a swing frame mechanism 7;

[0050] The support frame mechanism 6 is mounted on the main frame mechanism;

[0051] The swing frame mechanism 7 is mounted on the support frame assembly in a height-adjustable manner. The height can be adjusted according to the trainee's height and training needs during training.

[0052] In some embodiments, by setting up the support frame mechanism 6 and the swing frame mechanism 7, the strength training device is no longer limited to deadlifts, but can also support diverse training movements such as the Bulgarian split squat. The Bulgarian split squat is an efficient exercise for training the glutes and lower limb muscles, which can better activate the gluteal muscles, hamstring muscles, and core muscles, making the training more comprehensive. When performing Bulgarian split squat training, the trainee adjusts the swing frame mechanism 7 to a suitable height according to their physical condition and training needs, uses the swing frame mechanism 7 as a support point for the lower leg, places one leg on the swing frame mechanism 7, and stands on the foot pedal mechanism 5 to perform a single-leg squat, thus completing the Bulgarian split squat training.

[0053] Preferably, the adjustment mechanism 3 includes an adjustment support frame 31 and two first adjustment components 33;

[0054] One end of the adjustable support frame 31 is connected to the upright frame 2 so that it can swing up and down relative to the upright frame 2, and has two symmetrical free ends;

[0055] Two first adjustment components 33 are symmetrically fixed to the two free ends of the adjustment support frame 31.

[0056] In some embodiments, the adjustable support frame 31 is hinged to the upright frame 2 via a first pivot 32. When the trainee is training, the adjustable support frame 31 is pulled up or lowered, and the adjustable support frame 31 swings up and down relative to the upright frame 2 about the first pivot 32.

[0057] In some embodiments, the adjustable support frame 31 is U-shaped, with two symmetrical free ends at the two ends of the U-shaped opening. Two first adjustment components 33 are symmetrically fixed to the two free ends to ensure that when the trainee stands on the foot pedal mechanism 5 to perform deadlift training and other actions, the handles on both sides of the body can be adjusted and moved synchronously to maintain the balance and consistency of the movements, avoid body imbalance or uneven muscle force caused by improper adjustment on one side, and improve the training effect and comfort.

[0058] In some embodiments, a balance iron 34 is provided at the end of the adjustable support frame 31 connected to the upright to ensure stable operation of the adjustable support frame 31. The balance iron 34 can prevent unnecessary lateral or rotational movements, improving the safety and reliability of training.

[0059] Preferably, the first adjustment component 33 includes a first adjustment disc 331 and a first adjustment pin 332;

[0060] The first adjustment plate 331 is symmetrically fixed to the two free ends of the adjustment support frame 31. The first adjustment plate 331 is provided with a fixing hole, and several first adjustment holes A are evenly opened along the adjustment direction of the handle mechanism 4. It provides trainees with a variety of adjustment gears. This multi-gear design makes the height adjustment of the handle more precise. Trainees can choose the handle height that best suits them according to their own needs and training goals to ensure the accuracy and effectiveness of training movements.

[0061] The first adjusting pin 332 passes through the handle mechanism 4 and is fixedly inserted into the corresponding first adjusting hole A. The design of the first adjusting pin 332 makes the locking and unlocking process of the handle simple and quick. Trainees only need to insert or pull out the first adjusting pin 332 into the corresponding first adjusting hole A to fix or adjust the height of the handle, without complicated operating steps, saving preparation time before training and adjustment time during training.

[0062] In some embodiments, the adjustment holes on the first adjustment disc 331 are marked or spaced, allowing trainees to intuitively identify the position of each adjustment hole and quickly find the adjustment level suitable for their height and training needs, thus improving the convenience and accuracy of operation.

[0063] Preferably, the connecting end of the handle mechanism 4 is positioned on the first adjustment plate 331 in a manner that allows it to swing up and down relative to the first adjustment plate 331. A first adjustment pin insertion hole corresponding to the first adjustment hole A is provided on the handle mechanism 4. The first adjustment pin 332 passes through the first adjustment pin insertion hole and is fixedly inserted into the corresponding first adjustment hole A. The cooperation between the first adjustment pin 332, the first adjustment pin insertion hole, and the first adjustment hole A forms a reliable locking mechanism. When the first adjustment pin 332 is inserted into the first adjustment hole A through the first adjustment pin insertion hole, the height of the handle can be firmly fixed, ensuring the handle remains stable during training and preventing accidental movement due to external forces, thus ensuring the accuracy and safety of training movements.

[0064] In some embodiments, the handle mechanism 4 includes a handle connecting rod 41 and a handle 43. One end of the handle connecting rod 41 is hinged to the first adjusting plate 331 through a second rotating shaft 42 passing through a fixing hole, and a first adjusting pin insertion hole corresponding to the first adjusting hole A is provided on it. The other end of the handle connecting rod 41 is fixedly connected to the handle 43.

[0065] In some embodiments, the handle 43 includes a first handle and a second handle. The second handle is located inside the connecting rod 41 and is closer to the trainee than the first handle. By setting handles at different distances from the trainee, the training needs of trainees with different arm lengths can be accommodated.

[0066] In some embodiments, the strength training devices to which the height-adjustable handle mechanism 4 is applicable include, but are not limited to, deadlift trainers and deadlift hip trainers. The deadlift trainer can be used alone for deadlift training, while the deadlift hip trainer, by providing a height-adjustable swing frame mechanism, can be used for both deadlift training and squat training, such as Bulgarian squat training.

[0067] Preferably, the support frame mechanism 6 includes a support frame body and a second adjustment component 63;

[0068] Support frame, mounted on the uprights and / or base frame;

[0069] The second adjustment component 63 is mounted on the support frame.

[0070] In some embodiments, the support frame includes a first support rod 61 and a second support rod 62; one end of the first support rod 61 is fixedly connected to the first support crossbar 21 of the upright frame 2, and the other end is fixedly connected to the second support rod 62; the second support rod 62 is erected on the second support crossbar 11 of the base frame 1; and a second adjustment component 63 is disposed on the second support rod 62.

[0071] In some embodiments, the first support rod 61 and the second support rod 62 form a T-shaped structure, providing highly stable support for the swing frame mechanism 7.

[0072] In some embodiments, the first support rod 61 has a plurality of cable slots for the counterweight cable 85 to pass through.

[0073] Preferably, the second adjustment component 63 includes a second adjustment disc 631 and a second adjustment pin 632;

[0074] The second adjustment plate 631 is set on the second support rod 62, and several second adjustment holes B are evenly opened on it along the adjustment direction of the swing frame mechanism 7; providing trainees with a variety of adjustment gears. This multi-gear design makes the height adjustment of the swing mechanism more precise. When trainees perform Bulgarian squat training, they can choose the most suitable swing frame height according to their own needs and training goals to ensure the accuracy and effectiveness of the Bulgarian squat movement.

[0075] The second adjusting pin 632 is inserted into the swing mechanism and fixed in the corresponding second adjusting hole B.

[0076] Preferably, the swing frame mechanism 7 includes a swing rod 71 and two foam shafts 73;

[0077] The swing rod 71 is mounted on the second support rod 62 in a manner that allows it to swing up and down relative to the second support rod 62. It has a second adjusting pin insertion hole corresponding to the second adjusting hole B. The second adjusting pin 632 passes through the second adjusting pin insertion hole and is fixed in the second adjusting hole B corresponding to the position, so as to realize the height adjustment and locking of the swing rod 71.

[0078] Two foam rollers 73 are symmetrically mounted on the swing bar 71. The foam rollers 73 provide stable support for the trainee's calves. When performing single-leg support exercises such as Bulgarian split squats, the foam rollers 73 can effectively distribute the pressure on the calves, prevent the calves from slipping or wobbling during training, ensure the stability of the training movements, and reduce the risk of injury.

[0079] In some embodiments, the swing arm 71 is hinged to the second support arm 62 via a third pivot 72.

[0080] Preferably, the strength training device also includes a counterweight mechanism 8, which is connected to the adjustment mechanism 3 via a transmission connection.

[0081] Preferably, the counterweight mechanism 8 includes a counterweight frame 81, a set of insert-type counterweight blocks 82, a counterweight pulley system, and a counterweight steel cable 85;

[0082] The counterweight frame 81 is fixedly connected to the upright frame 2 mechanism via the connecting frame assembly 9;

[0083] The set of insert-type counterweights 82 includes multiple insert-type counterweights 82 stacked vertically, with the first insert-type counterweight 821 located at the top. Each insert-type counterweight 82 has a limiting hole C.

[0084] The counterweight pulley system includes a first counterweight pulley system 83 and a second counterweight pulley system 84. The first counterweight pulley system 83 is mounted on the adjusting mechanism 3, and the second counterweight pulley system 84 is mounted on the base frame 1.

[0085] One end of the counterweight cable 85 is fixed to the base frame 1 and passes around the counterweight pulley group to connect with the insert-type counterweight block 82 group.

[0086] In some embodiments, the connecting frame assembly 9 includes two connecting frames that fix the base frame 1 and the counterweight frame 81. Through the structure of the connecting frame assembly 9, the counterweight frame 81 can form a tight connection with the main frame mechanism, so that the entire strength trainer can withstand greater external forces and training loads during use, reduce swaying or collapse caused by unstable support, and improve the safety and reliability of training.

[0087] In some embodiments, such as Figure 2As shown, the first counterweight pulley group 83 includes a first movable pulley 831 and a second movable pulley 832, and the second counterweight pulley group 84 includes a first fixed pulley 841, a second fixed pulley 842 and a third movable pulley 843. One end of the counterweight steel cable 85 is fixed to the base frame 1, and passes through the first movable pulley 831, the first fixed pulley 841, the second movable pulley 832, the second fixed pulley 842 and the third movable pulley 843 in sequence to connect with the insert-type counterweight block 82 group to complete the transmission and reversal of force.

[0088] In some embodiments, the counterweight mechanism 8 further includes two elastic damping bands, not shown in the figure, which are symmetrically arranged in the guide grooves D on both sides of the counterweight frame 81. The elastic damping bands have a fixed end and a moving end. The fixed end is fixedly connected to the counterweight frame 81, and the moving end is detachably fixedly connected to the first insert-type counterweight block 821 through a guide shaft 87.

[0089] In some embodiments, the counterweight source may be at least one of insert-type counterweight block 82 or elastic damping band.

[0090] In some embodiments, if the trainee selects the insert-type counterweight block 82 as the counterweight source during training, the insert 86 must first be inserted into the limiting hole C corresponding to the selected weight of the insert-type counterweight block 82 to complete the counterweight selection. When the trainee performs deadlift training, the adjustment mechanism 3 is pulled up by the trainee, and the first counterweight pulley group 83 set on the adjustment mechanism 3 moves upward accordingly. After the force is transmitted and reversed through the second pulley group set on the base frame 1 via the counterweight steel cable 85, the selected insert-type counterweight blocks 82 are pulled upward, thereby generating corresponding resistance to the movement of the adjustment mechanism 3.

[0091] In some instances, if the trainee selects a single elastic damping band or a combination of an elastic damping band and a plate-type counterweight 82 as the counterweight source during training, the guide shaft 87 needs to be inserted into the fixing bolt at the top of the first plate-type counterweight 821 to fix the elastic damping band to the first plate-type counterweight 821. When the trainee performs a deadlift, the adjusting mechanism 3 is pulled up, causing the first counterweight pulley group 83 mounted on the adjusting mechanism 3 to rise. The force is transmitted and reversed through the counterweight cable 85 via the second pulley group mounted on the base frame 1, pulling the selected first plate-type counterweight 821 upward. Since the moving end of the elastic damping band is fixedly connected to the first plate-type counterweight 821, the moving end of the elastic damping band moves together with the first counterweight, causing the elastic damping band to stretch and generate resistance. Due to the elastic properties of the damping belt, it generates resistance to the movement of the adjustment mechanism 3. This resistance increases as the damping belt stretches, providing a variable resistance that is related to the amplitude of movement.

[0092] In some embodiments, trainees can adjust the weight source as needed, using a single insert-type weight block 82, a single elastic damping band, or both, to meet the different training needs of different trainees. When the weight source is a single insert-type weight block 82, the guide shaft 87 needs to be removed from the fixing bolt at the top of the first insert-type weight block 821 to release the fixed connection between the elastic damping band and the first insert-type weight block 821. For other options, the guide shaft 87 needs to be inserted into the fixing bolt at the top of the first insert-type weight block 821 to fix the elastic damping band to the first insert-type weight block 821. Through the configuration of multiple weight source options, trainees can flexibly adjust the difficulty and intensity of training according to their training goals and abilities, providing not only diverse training options but also increasing the safety and effectiveness of training.

[0093] In some embodiments, the counterweight mechanism 8 further includes a counterweight protection cover 88 disposed on the counterweight frame 81, which is used to prevent trainees from accidentally contacting the counterweight block or the moving parts of the counterweight mechanism 8 during training, thereby reducing the risk of injury and enhancing safety.
