Abstract
Description
Technical Field
[0001] This utility model relates to the field of fitness equipment technology, specifically to a pendulum squat trainer. Background Technology
[0002] Weighted squats provide intense stimulation to the entire lower limbs and torso, effectively training the quadriceps, gluteus maximus, biceps femoris, semitendinosus, and semimembranosus, as well as the erector spinae, piriformis, adductor magnus, gluteus medius, gluteus minimus, and calf muscles. Chinese patent document (CN213555183U) discloses a squat training machine with an adjustable pedal angle, including a base, a lifting frame hinged to the base, and pedals mounted on the base. The lifting frame is equipped with weights and shoulder pads located above the pedals. By adjusting the pedal angle, the angles at the ankle and knee joints can be adjusted according to the needs of the targeted muscle groups and the user's height. However, when squatting to a low position, it becomes difficult to generate power, and the squatting process relies solely on the shoulders and back for support, lacking cushioning, resulting in significant impact on the knees. Utility Model Content
[0003] The purpose of this invention is to provide a pendulum squat trainer that can provide a counter-force to distribute the downward force of the swing assembly and play a buffering role, thereby reducing the negative impact on the knees.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] The pendulum squat trainer includes a fixed frame, a swing assembly, and a tension variable resistance mechanism. The swing assembly is rotatably mounted on the fixed frame. One end of the tension variable resistance mechanism is connected to the fixed frame, and the other end is connected to the rear of the swing assembly. When the rear of the swing assembly swings upward around the pivot point between itself and the fixed frame, it provides a downward pulling force to the rear of the swing assembly, and the force value increases.
[0006] Preferably, the tensioning variable resistance mechanism is a tension spring.
[0007] Preferably, the number of tension springs is one or two, and the two ends of each tension spring are respectively connected to the swing assembly and the fixed frame.
[0008] Preferably, the swing assembly has an upper hanger at the rear and the fixed frame has a lower hanger at the rear. Both the upper and lower hangers have hanging holes, and the tension spring has hooks at both ends, which are hooked into the hanging holes.
[0009] Preferably, the swing assembly has an upper hanging shaft at the rear and a lower hanging shaft at the rear of the fixing frame. Limiting components are detachably provided on the upper hanging shaft and the lower hanging shaft respectively. The two ends of the tension spring are respectively wrapped around the upper hanging shaft and the lower hanging shaft and held on the upper hanging shaft and the lower hanging shaft by the limiting components.
[0010] Preferably, the pendulum squat trainer further includes a fall protection mechanism, which includes a fall protection bar fixedly mounted on a fixed frame and a fall protection plate rotatably mounted on the swing assembly. The fall protection plate is engaged with the fall protection bar to keep the swing assembly from falling, and the fall protection plate deviates from the fall protection bar during the up-and-down swing of the swing assembly.
[0011] Preferably, the upper end of the fall arrestor plate is a hook end and the lower end is a counterweight end, and the middle part of the fall arrestor plate is rotatably mounted on the swing assembly via a rotating shaft.

Detailed Implementation
[0023] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.
[0024] like Figures 1-5 As shown, this embodiment provides a pendulum squat trainer, including a fixed frame 100, a swing assembly 200 and a tension variable resistance mechanism 300. The swing assembly 200 is rotatably mounted on the fixed frame 100, and one end of the tension variable resistance mechanism 300 is connected to the fixed frame 100 and the other end is connected to the rear of the swing assembly 200.
[0025] In this embodiment, the fixing frame 100 includes a base frame, a vertical frame fixedly installed on the rear side of the base frame, and a column fixedly installed on the side of the base frame. The side of the vertical frame is provided with a first bell hanger, on which the bells are hung when not training. A fall arrestor 103 is fixedly installed on the top of the column. The base frame is provided with a pedal 101, the bottom end of which is rotatably connected to the base frame, and the upper end of the pedal 101 is connected to the base frame through an angle-adjustable component to achieve angle adjustment of the pedal 101. The angle-adjustable component is a conventional structure and will not be described in detail here.
[0026] In addition, a head-limiting component 102 is fixedly connected to the front of the base frame. The height of the head-limiting component 102 is adjustable to meet the needs of people with different flexibility and ensure safe movement. The height adjustment can be achieved using a conventional structure of pins and holes. The head-limiting component 102 is located in the downward swing path of the swing assembly 200 to prevent the swing assembly 200 from directly impacting the base frame when it accidentally falls. Preferably, a buffer pad is fixedly provided on the top of the head-limiting component 102 to provide a cushioning effect.
[0027] In this embodiment, the swing assembly 200 includes a swing frame 20 and a hanging bar 24, a back pad 21, a shoulder pad 22, and a fixed handle 23 respectively installed at the head of the swing frame 20. The rear of the swing frame 20 is mounted on the upper part of the upright frame via a horizontal shaft and bearing seat, so that the swing frame 20 can swing up and down relative to the fixed frame 100 to perform squat training. The installation method of the back pad 21, shoulder pad 22, and fixed handle 23 with the swing frame 20 is a conventional structure and will not be described in detail here. Figure 3 As shown.
[0028] A fall prevention mechanism is provided between the side of the swing frame 20 and the column of the fixed frame 100 to keep the swing frame 20 in a stable position. The fall prevention mechanism includes a fall prevention rod 103 fixedly mounted on the column of the fixed frame 100 and a fall prevention hanging plate 24 rotatably mounted on the side of the swing frame 20. The upper end of the fall prevention hanging plate 24 is a hook end, and the lower end is a counterweight end. The middle part of the fall prevention hanging plate 24 is rotatably mounted on the swing frame 20 via a pivot. The fall prevention hanging plate 24 engages with the fall prevention rod 103 to prevent the swing assembly 200 from falling. During the up-and-down swing of the swing assembly 200, the fall prevention hanging plate 24 deviates from the fall prevention rod 103 without affecting the up-and-down swing of the swing frame 20. Because the counterweight end is at the bottom, the hook end of the fall prevention hanging plate 24 will deflect away from the fall prevention rod 103 around the pivot when no external force is applied. In addition, to facilitate keeping the swing assembly 200 from swinging before the end of training, the lower end of the fall arrestor plate 24 is also connected to an operating handle 25. The trainee can manually swing the operating handle 25 to make the hook end able to be attached to the fall arrestor bar 103. Preferably, there are multiple fall arrestor bars 103 arranged vertically and staggered at different horizontal heights.
[0029] In this embodiment, the tension variable resistance mechanism 300 is a tension spring, and the number is one or two (two tension springs are shown in the figure). The two ends of each tension spring are respectively connected to the upright of the swing assembly 200 and the fixed frame 100.
[0030] The connection method between the tension spring and the swing assembly 200 and the upright can be, but is not limited to, the following:
[0031] In some examples, the swing assembly 200 has an upper hanger at the rear and the fixed frame 100 has a lower hanger at the rear. Both the upper and lower hangers have hanging holes, and the two ends of the tension spring have hooks that are hooked into the hanging holes.
[0032] In some examples, such as Figure 5 As shown, the swing assembly 200 has an upper hanging shaft at the rear, and the fixed frame 100 has a lower hanging shaft at the rear. Limiting components are detachably provided on the upper hanging shaft and the lower hanging shaft respectively. The two ends of the tension spring are respectively wrapped around the upper hanging shaft and the lower hanging shaft and held on the upper hanging shaft and the lower hanging shaft by the limiting components.
[0033] The training process of the pendulum squat trainer in this embodiment is as follows: Adjust the pedal 101 to a suitable angle. During training, the body rests on the shoulder pad 22 and back pad 21 respectively, with the feet on the pedal 101. Hold the fixed handle 23 and perform squatting and lifting reciprocating training movements. The equipment completely wraps the shoulders and back of the body, better protecting the body and focusing only on leg strength training. During training, the swing assembly 200 swings up and down. The tension variable resistance mechanism 300 provides a downward pulling force on the rear of the swing assembly 200 during the upward swing process around the rotation fulcrum between it and the fixed frame 100, and the force value increases. When squatting, the tension variable resistance mechanism 300 is stretched to counteract the downward pressure on the body. The lower the body is, the greater the force that is counteracted.
[0034] When you start exercising, the fall arrestor plate 24 will automatically pop open when you push your body upwards. When you want to stop exercising, simply hang the fall arrestor plate 24 on the fall arrestor bar 103 in a suitable position. The head limit component 102 can be adjusted to limit the height by means of a pin to meet the needs of people with different flexibility and ensure safe exercise.
[0035] The foregoing has shown and described the basic principles, main features and advantages of this invention. Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are only illustrative of the principles of this invention. Various changes and modifications can be made to this invention without departing from the spirit and scope of this invention. All such changes and modifications fall within the scope of this invention as defined by the appended claims and their equivalents.
