Description

Technical Field

[0001] The utility model belongs to the technical field of fitness equipment, and particularly relates to a lunge trainer. Background Art

[0002] Lunge trainers generally refer to those fitness equipment designed to mimic the lunge movement, mainly used to exercise the lower limb muscles, especially the buttocks, thighs and calves.

[0003] In modern fitness training equipment, the design and function of the trainer directly affect the user's training effect and experience. Taking the sliding training device disclosed in Patent CN220404741U as an example, the prior art aims to help users train lower limb strength and flexibility, especially for lunges and lunging movements. The device mainly uses the cooperation of a sliding pedal and a stepping part to help users perform lunges. Specifically, the user steps on the stepping part with the left foot and on the pedal with the right foot, and the sliding of the pedal is realized through a chute to assist the lunging movement of the right leg.

[0004] However, the prior art is mainly used for lunges or lunging movements, with a relatively single function. As fitness enthusiasts' pursuit of comprehensive exercise grows, it is difficult for this device to meet users' needs for a whole-body or diversified training program in terms of functional diversity; during use, the stability of the sliding pedal may be insufficient, which may cause users to lose balance when attempting complex or large-scale movements, thereby affecting the training effect and even posing a safety risk.

[0005] Therefore, there are problems of single function and poor stability in the prior art. Summary of the Utility Model

Thus, the features defined with "first", "second", "third" may explicitly or implicitly include one or more of such features.

[0053] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", "connection" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a direct connection, or an indirect connection through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0054] As shown in the attach Figure 1 ment, in a schematic embodiment of the lunge trainer of the present invention, the frame of the lunge trainer includes: a chassis 1, the chassis 1 includes two horizontally arranged parallel beam frames 11, and further includes:

[0055] The first support part 2 is arranged at the first end of the chassis 1. Installation grooves are oppositely arranged inside the horizontal beam frame 11 to facilitate the installation of the first support part 2. In the default state, the first support part 2 is fixedly arranged at the first end of the chassis 1, that is, its front end.

[0056] The second support part 3 is slidably arranged on the chassis 1 through a linear sliding mechanism, and slides close to or away from the first support part 2. The first support part 2 is used for placing the front leg when the user is exercising, and the second support part 3 is used for placing the rear support leg when the user is exercising. When performing a lunge, the rear support leg can drive the second support part 3 to slide away from the first support part 2 until the rear support leg is extended to complete the lunge movement of the kneeling position.

[0057] The vertical frame 12 is fixedly arranged at the second end of the chassis 1, that is, on both sides and / or in the middle of the rear end thereof.

[0058] The left support 13 and the right support 14 are respectively hinged on the vertical frame 12 and adjusted up and down around it. Support legs 15 are respectively arranged at the front ends of the left support 13 and the right support 14. The support legs 15 can stand on the chassis 1 or the training plane, such as the ground. Holding parts 4 are respectively arranged at the actuating ends of the left support 13 and the right support 14. Based on the left support 13, the right support 14 and the support legs 15, good support can be provided, the stability of the equipment can be increased, and at the same time, it is ensured that the user will not be injured due to the instability of the equipment or himself during the lunge training.

[0059] Wherein, weight installation rods 16 facing outward are arranged on the left support 13 and the right support 14 for hanging components such as dumbbell plates and counterweight blocks to provide resistance for lifting the left support 13 and the right support 14. Weight installation rods 16 facing outward are also arranged on the vertical frame 12 for storing components such as dumbbell plates and counterweight blocks after the exercise.

[0060] In addition, a counterweight block 5 is fixedly arranged at the hinged ends of the left support 13 and the right support 14 respectively. When the user holds the holding part 4 and lifts the left support 13 and / or the right support 14, the user's hand provides an upward force for the front ends of the left support 13 and the right support 14, and the counterweight block 5 provides a downward force for the tail ends of the left support 13 and the right support 14, playing a role of balance and stability. At the same time, the force that needs to be exerted by the user's hand is reduced through the setting of the counterweight block 5, so that the user can more easily lift and control the support.

[0061] Combined Figure 4 As shown, in the above embodiment, the linear sliding mechanism is fixedly installed between the front end and the rear end of the chassis 1. The linear sliding mechanism adopts an orbital structure 31 provided with at least one chute and / or a sliding rod structure in which at least two sliding rods are used in cooperation.

[0062] At the first end and the second end of the horizontal beam frame 11 of the chassis 1, a first cross beam 111 and a second cross beam 112 are respectively provided. The front end and the rear end of the linear sliding mechanism are respectively installed on the first cross beam 111 and the second cross beam 112, or the front end and the rear end of the linear sliding mechanism are respectively installed on the first cross beam 111 and the vertical frame 12. The height of the front end of the linear sliding mechanism is less than or equal to the height of the rear end of the linear sliding mechanism. When the height of the rear end is greater than the height of the front end, the training effect of the Bulgarian split squat can be achieved, more concentratedly stimulating the quadriceps and gluteal muscles of the front leg, and enhancing the training difficulty of core strength and leg strength.

[0063] In order to achieve the change between the two movements, the front end of the linear sliding mechanism can also be set to be hinged on the first cross beam 111, and the rear end can be set to be height-adjustable on the second cross beam 112 or the vertical frame 12, or the second cross beam 112 can be set to be height-adjustable on the vertical frame 12, all of which can achieve the adjustment of the height of the rear end of the linear sliding mechanism. Existing height adjustment mechanisms can be combined here, such as the mechanical method of using a pin shaft to combine with a height adjustment bracket, or height adjustment mechanisms such as slide rails, air pressure, and hydraulic pressure.

[0064] In another embodiment, with reference to Figure 2 As shown, the left bracket 13 and the right bracket 14 are detachably connected by a connecting structure. When the connecting structure is in the connected state, the left bracket 13 and the right bracket 14 are connected together and can move synchronously; when the connecting structure is in the disassembled state, the left bracket 13 and the right bracket 14 are separated and can move independently, or other asymmetric training movements, increasing the diversity of training.

[0065] It should be noted that the left bracket 13 and the right bracket 14 can be directly connected by the connecting structure, or indirectly connected by the connecting structure. For example, relatively arranged connecting pieces are fixedly connected to the left bracket 13 and the right bracket 14, and the connecting structure is arranged on the connecting pieces. The connecting pieces can be hollow pipes.

[0066] Among them, as Figure 3 As shown, the connecting structure of the above embodiment includes: two pin holes 6 and a linkage pin 7. The two pin holes 6 penetrate through the connecting ends of the left bracket 13 and the right bracket 14 relatively. If connecting pieces are provided on the left bracket 13 and the right bracket 14, the pin holes 6 can be penetrated through the connecting pieces; the linkage pin 7 is slidably arranged in an adjustable manner in any one of the pin holes 6, and through the adjusting member of the linkage pin 7, the pin body slides in and out of the other pin hole 6 during the sliding process, realizing the automatic insertion and extraction of the linkage pin 7, further improving the operation convenience.

[0067] Furthermore, the adjusting member is an operating rod 8 fixedly arranged on the bolt body, and correspondingly, a through groove adapted to the operating path of the operating rod 8 is provided on the left bracket 13, the right bracket 14 or the connecting member, and / or a driving device is provided in the left bracket 13, the right bracket 14, and the driving device is connected to the bolt body through transmission.

[0068] In the above embodiment, the driving device includes a motor, an electric push rod, a linear actuator, a gear or rack mechanism, etc., which is used to convert electrical energy into mechanical motion, thereby driving the movement of the bolt. In another embodiment, the motion generated by the driving device can be converted into the linear motion required by the bolt through a transmission mechanism. The transmission mechanism includes components such as connecting rods, sliders, gears, and synchronous belts.

[0069] In order to realize the electric control of the linkage bolt 7, the driving device also includes a control system for receiving external signals, such as button operation signals and / or sensor signals, and controlling the movement of the driving device and the transmission mechanism according to a preset logic, thereby realizing the automatic insertion and extraction of the bolt. The realization of the control logic is not described in detail here. The control system includes components such as a controller, a sensor, and an actuator.

[0070] When a button operation control is adopted, the button can be arranged near the grip portion 4, and configured so that when the button is pressed, the linkage latch 7 switches between the inserted and removed states;

[0071] Or the button is replaced by an adjusting knob, and the knob is set to correspond to the insertion state and the removal state, and the linkage latch 7 is adjusted to the insertion state or the removal state in a targeted manner by adjusting the knob;

[0072] When sensor signal control is adopted, the sensor can be arranged on the holding part 4 to detect whether the holding part 4 of the left bracket 13 and the right bracket 14 is held by the user. For example but not limited to, if both hands hold the holding part 4, the insertion of the pin is automatically controlled; if one of the holding parts 4 is held by one hand, the removal of the pin is automatically controlled. The specific model of the sensor is not illustrated here, and technical personnel in this field can flexibly select it.

[0073] Based on the above structure, the user can control the state of the latch through buttons or sensor signals, thereby quickly switching between different training modes to meet different training needs.

[0074] In another embodiment, if Figure 5As shown in the figure, the receiving linkage bolt 7 is inserted into or withdrawn from the bolt hole 6 in which two oppositely arranged sliding parts 61 and two limiting parts 62 are provided. A first distance is provided between the two oppositely arranged sliding parts 61. The two limiting parts 62 are oppositely arranged between the two sliding parts 61. A second distance is provided between the two limiting parts 62. The first distance is greater than the second distance. A clamping space is formed by enclosing between the two sliding parts 61 and the two limiting parts 62. The cross-sectional shape of the end face of the linkage bolt 7 is the same as the cross-sectional shape of the clamping space. After the linkage bolt 7 is inserted into the clamping space and rotated by a preset angle, the clamping space restricts the further rotation of the linkage bolt 7, and / or the clamping space is used to hinder the reverse rotation of the linkage bolt 7, that is, the rotated linkage bolt 7 is squeezed by the clamping space so that it cannot rotate in the clamping space, thereby making the connection between the left bracket 13 and the right bracket 14 relatively stable and avoiding shaking to affect the use feeling of the trainer.

[0075] In some embodiments, the holding part 4 is connected to the actuating end through an angle adjusting device, and different included angles and / or distances are provided between the holding part 4 and the left bracket 13 and the right bracket 14 through the angle adjusting device. Specifically, the angle adjusting device includes:

[0076] An installation part 41, on which a plurality of adjustment holes 42 are provided. The installation part 41 is arranged on the left bracket 13 and the right bracket 14. The holding part 4 is hinged to the installation part 41. A jack 43 adapted to the adjustment hole 42 is provided on the holding part body or its extended structure. The angle adjusting bolt 44 is detachably inserted into the jack 43. Among them, the extended structure refers to an extended section fixedly arranged at the hinged end of the holding part 4, and the jack 43 is provided on the extended section. Optionally, the angle adjusting bolt 44 is an elastic bolt.

[0077] During use, after aligning the jack 43 with different adjustment holes 42, insert the angle adjusting bolt 44 into the aligned jack 43 and adjustment hole 42, and different included angles can be provided between the holding part 4 and the left bracket 13 or the right bracket 14. Such an angle adjusting device is simple and practical and easy to adjust. Users can find the most comfortable and effective training posture according to their own physical conditions and training needs.

[0078] In another embodiment, in order to improve the adjustment dimension of the angle adjusting device, the installation part 41 can also be fixedly installed on an adjustment bracket. The adjustment bracket is used to realize multi-directional position movement, such as adjusting the horizontal forward extension and retraction through a horizontal bracket extending from the left bracket 13 and the right bracket 14, and / or adjusting the height in the vertical direction through an upright bracket perpendicular to the horizontal bracket and extending upward, so that the adjustment of the holding part 4 is more flexible and adapts to users with different heights and training needs.

[0079] In another embodiment, the angle adjustment device can also be set to include: a multi-degree-of-freedom adjustment unit fixedly arranged on the left bracket 13 and the right bracket 14. The multi-degree-of-freedom adjustment unit is a multi-axis robotic arm or a spherical joint; the holding part 4 is fixedly installed on the multi-degree-of-freedom adjustment unit, enabling the user to adjust in multiple degrees of freedom, improving the applicability of the device and enhancing the user's training effect.

[0080] In another embodiment, to adapt to the heights of different users, the first support part 2 is movably and fixedly arranged on the chassis 1. When the user expects to shorten the training distance, the first support part 2 can be moved towards the second support part 3 and limited. The limiting method can be to set matching locking holes on the chassis 1 and the first support part 2. When the first support part 2 moves to the required position, the first support part 2 is fixed on the chassis 1 by rotating a locking bolt, pressing a locking buckle, or inserting a locking pin, etc.

[0081] In another embodiment, a support part is provided at the front end and / or the rear end of the first support part 2; among them, when the support part is arranged at the front end of the first support part 2, it can be set as a support pad or a support plate structure, and its supportable range is a certain height above the pedal. The bottom of the support part is arranged above the instep of the user's foot, maintaining the stability of the front foot during the lunge squat, preventing the user's front foot sole or toes from lifting during the lunge squat due to insufficient strength or unskilled movements, thus affecting the standardization and effect of the movement, and also helping to keep the front foot sole flat on the ground, contributing to improving the movement posture, ensuring the accuracy and effect of the training. During exercise, the front foot needs to bear a large body weight and ground reaction force, and the support part can also be used to disperse these pressures, reduce the burden on the foot, and lower the risk of injury;

[0082] The top height of the support part is set to be higher than or equal to the user's knee to prevent the user's knee from moving forward excessively during training, ensuring the safety and effectiveness of the exercise by standardizing the exercise posture.

[0083] When the support part is arranged at the rear end of the first support part 2, it can be set as a support pad, a support plate, or a safety belt connected to the support part at the front end of the first support part 2, to support the back of the calf of the user's front leg, reduce muscle fatigue and discomfort caused by long-term or high-intensity lunge squats, make the front leg more stable during the lunge squat, contribute to maintaining the correct movement posture and center of gravity distribution, and thus improve the stability and safety of the entire movement process.

[0084] In another embodiment, the support part can be set to have an adjustable height structure, such as including a lifting groove, a positioning hole, and a clamping component, to be applicable to users of different heights.

[0085] The support pad in the above embodiments is made of a soft and breathable material to provide user comfort.

[0086] In another embodiment, the left support 13 and the right support 14 are provided with first mounting rods 17 facing outward, and the base frame 1 is correspondingly provided with second mounting rods 18 for the first mounting rods 17. An elastic member can be mounted between the first mounting rod 17 and the second mounting rod 18.

[0087] In the above embodiments, dumbbell plates, counterweights, and elastic members (such as springs, elastic bands, etc.) are used as resistance sources. When the user attempts to lift the left support 13 and the right support 14, they need to overcome the resistance generated by the counterweights or elastic members, thereby promoting the growth of muscle strength and the improvement of endurance. The magnitude of the counterweight resistance depends on the number and weight of the mounted items, and the magnitude of the elastic member resistance depends on the stiffness of the elastic member and the mounting method. The user can select an appropriate resistance magnitude according to their training level and goals.

[0088] In summary of the above, the step - squat trainer of this embodiment allows the second support part to slide on the base frame to meet the requirements of different step lengths, allows the adjustment of the height of the rear end of the sliding mechanism, and can support standard step - squats and Bulgarian step - squats. The left support and the right support are detachably connected, allowing the user to perform synchronous two - hand or independent one - hand movements, increasing the diversity and flexibility of the exercise; through the design of the left and right supports and their supporting legs, a stable support is provided to ensure the stability of the training process and reduce the risk of user injury. The counterweights provide balance and stability, making the user's operation easier and safer; through the linkage pin, the connection and separation adjustment of the left and right supports are simple and fast, improving the training diversity. Allowing electric control of the pin insertion and extraction further enhances the operation convenience. The step - squat training machine of this embodiment provides users with an efficient, safe, and diverse training experience with its advantages of flexibility, stability, versatility, convenience, and adaptability.

[0089] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts among the various embodiments can be referred to each other.
