Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fitness equipment, in particular to a sitting tibialis anterior muscle calf comprehensive trainer. BACKGROUND

[0002] At present, in the field of fitness equipment, although training equipment for calf muscle groups is widespread, there are significant limitations in design concept and function implementation. The existing devices, such as traditional sitting or standing calf machines, are highly specialized in function and are almost completely designed around the concentric contraction of the posterior calf muscle group (gastrocnemius and soleus) (calf raising action). The direct consequence of this design is that it completely ignores the training of the tibialis anterior muscle, which is located on the anterior side of the calf and serves as an antagonistic muscle group. Therefore, there is no solution in the existing technology that can effectively integrate tibialis anterior muscle training (hooking foot action) with traditional posterior calf muscle training (calf raising action) on the same device, resulting in the need for users to use multiple devices or adopt low-efficiency auxiliary training if they want to develop the calf muscle group comprehensively. Not only does this increase the cost and space occupation, but it also makes the training process cumbersome.

[0003] Secondly, the existing devices are not well considered in terms of ergonomic adaptability. These single-function devices often lack sufficient adjustment capabilities and are difficult to flexibly adapt to the physiological characteristics of users of different heights and leg lengths. More importantly, they generally lack adjustment functions for the initial angle of the training action, which means that users cannot perform fine-tuned training within different ranges of motion (ROM). This "one-size-fits-all" design not only reduces the comfort and standardization of training, but also limits the user's ability to precisely stimulate different parts of the target muscle group by adjusting the range of motion, thereby affecting the scientific nature and final results of the training.

[0004] Finally, in terms of the application of training resistance, the existing technology also appears to be relatively monotonous. Most devices only support the provision of constant resistance by mounting weight plates. Although this traditional resistance mode is effective, it cannot perfectly match the natural force curve of the muscle throughout the movement trajectory, especially during the peak contraction phase at the end of the action, where the stimulation provided is often insufficient. The existing devices generally do not innovatively integrate multiple weight-bearing methods, such as providing elastic band hooks to take advantage of their progressive resistance characteristics. This makes it difficult for users to strengthen their concentric and eccentric control through diverse resistance stimulation, and limits their training options for breaking through the strength plateau, which is not conducive to the overall improvement of muscle strength, endurance, and stability. SUMMARY

[0005] In view of the deficiencies of the prior art, the sitting tibialis anterior muscle calf comprehensive trainer is provided to solve the problems of single function, neglect of tibialis anterior muscle training, imbalance of calf muscle strength, and the need for multiple devices to complete comprehensive training.

[0009] The leg bag mechanism is installed on the main frame mechanism and is used for fixing the thighs of users and applying loads.

[0010] The foot pedal mechanism is hinged to the front part of the main frame mechanism and is used for the feet of users to step on to perform training actions.

[0012] Preferably, the foot pedal mechanism comprises two foot pedals, both of which are located on the two sides of the foot pedal group connecting seat and are connected with the foot pedal group connecting seat through a bearing group, the top of the foot pedal is provided with a foot cover, the inside of the foot pedal is rotatably connected with an angle adjusting gear, the opposite side between the two foot pedals is provided with an elastic band hook, and the side away from each other between the two foot pedals is provided with a counterweight piece hanging rod.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the specification of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0027] Please refer to the drawings of the present application Figure 1 - the drawings of the present application Figure 6 The embodiment of the present application provides a sitting tibialis anterior muscle calf comprehensive trainer, which comprises a main frame mechanism as a basic support structure of the whole trainer, a leg pack mechanism installed on the main frame mechanism for fixing thighs of a user and applying load, and a foot pedal mechanism hinged to the front of the main frame mechanism for the user to step with feet to perform training actions.

[0028] Embodiment one: stable and bearing main frame mechanism

[0029] The main frame mechanism in this embodiment is the cornerstone of the entire trainer's multi-functional training capabilities. Its robust structure provides absolute stability for all training modes, especially for heavy-load lower limb training.

[0030] The bottom frame of the main structure consists of a U-shaped tube 1 and a main crossbeam 2. A rear connecting tube 5 is installed inside the U-shaped tube 1. The main crossbeam 2 is connected to the rear connecting tube 5 via a connecting plate 25 and is supported forward by a front support frame 4, forming a wide T-shaped base. This base is firmly grounded by ground support feet 24, ensuring that the equipment body will not wobble during explosive concentric contractions of the tibialis anterior muscle or heavy eccentric control during calf training. For easy movement, casters 23 are provided at the rear end of the U-shaped tube 1, which, together with handle 22, allow for easy transport.

[0031] The main frame mechanism is designed to provide a crucial interactive interface for multi-mode training. An angled brace 27 is welded to the top of the main crossbeam 2, and a foot pedal assembly connecting seat 26 is fixed to its top, serving as the rotation center for all foot movements. Crucially, the counterweight hook 17 located at the front end of the main crossbeam 2 plays multiple roles in this embodiment: it is not only a support for storing counterweight plates but also a core anchor point for achieving the forefoot up-and-down training function. During this training, one end of the elastic band is connected to the foot pedal, and the other end is fixed to this hook, establishing an effective elastic connection between the main frame and the foot pedal, thereby achieving specific downward resistance training.

[0032] Example 2: Dual-role leg pack mechanism

[0033] The leg pack mechanism in this embodiment is the core of the invention for achieving function switching. It cleverly switches between the roles of "fixed fulcrum" and "active load" depending on the training objective.

[0034] The mechanism is rotatably connected to the main frame connector 28 installed at the rear of the main frame via the main connecting frame 3 and its internal seat cushion connector 29, and carries the seat cushion 7 for the user to sit on. Its height adjustability is the key to the universality of the equipment. The user can quickly adjust the height adjustment tube 30 through the height adjustment locking device 19, and further adjust the leg pack plane tube 6 by pulling up the handle 21, so that the two rotatable locking leg packs 20 at the bottom can be firmly pressed against the user's quadriceps muscles under the action of the rotating bearing 31, so as to accommodate users of different body types.

[0035] The agency's dual role is reflected in:

[0036] When performing calf training, as the main load source: At this time, the whole leg bag mechanism is in a non-locked state. The user performs the action of lifting the heel down, and the goal is to overcome and lift the weight of the whole leg bag mechanism. In order to achieve progressive overload, the user can hang the weight plate on the weight plate hanging rod 10 behind the main connecting frame 3, or connect the elastic band on the weight hook three 18, so as to greatly increase the training weight and efficiently stimulate the calf muscle group.

[0037] When performing tibialis anterior muscle training, as a stable reaction force point: At this time, the mechanism is locked, and its only function is to firmly fix the user's thigh to prevent the thigh from lifting off the seat cushion 7 due to compensation when performing the action of lifting the forefoot. This stable locking ensures that all forces are isolated from the tibialis anterior muscle, achieving precise target muscle stimulation.

[0038] Example three: foot pedal mechanism of multi-mode action execution core

[0039] The foot pedal mechanism in this embodiment is the direct execution end of all training actions, and its exquisite structure design is the key to realizing the coexistence of three functions.

[0040] Among them, two independent foot pedals 9 are installed through bearing groups 13, and this independent design accurately corresponds to the training needs, allowing users to perform synchronous training of both legs, or isolated training of single leg to improve the imbalance of muscle strength on both sides.

[0041] The mechanism realizes three functions through the following design:

[0042] Tibialis anterior muscle training is achieved: when the user performs the action of lifting the forefoot upward, the foot pedal 9 provides stable support for the heel. The load can be applied in two ways: one is to directly hang the weight plate on the weight plate hanging rod 10 outside the foot pedal 9 for constant resistance training; the second is to connect the elastic band on the elastic band hook 16 inside it, and use the rubber band to provide progressive resistance to strengthen the peak contraction.

[0043] Calf training is achieved: the user can adjust the initial plane angle of the foot pedal 9 to 0 degrees, 10 degrees, or 15 degrees, etc. through the angle adjustment gear 11 in combination with the limit handle 14. A larger inclination angle means that the calf muscle group is in a deeper stretching state at the starting point of the action, thereby increasing the effective stroke and stimulation depth of the training, achieving better muscle growth effect.

[0044] Realize the forefoot up and down muscle group and foot dorsiflexion ankle training: this function is realized through unique resistance setting. The user connects one end of the elastic band to the elastic band hook 16 of the foot pedal 9, and the other end to the weight hook two 17 of the main frame mechanism. After setting, the elastic band will generate a continuous, centrifugal upward pulling force on the foot pedal. The user needs to actively exert force to do the down pressure action with the forefoot to resist this upward pulling force, thereby effectively strengthening the training of the intrinsic muscle group of the forefoot and the surrounding synergistic muscle group, increasing the foot core resistance, and also effectively enhancing the muscle strength of the user's foot dorsum and ankle.

[0045] Embodiment four: function switching locking mechanism and linkage

[0046] The locking mechanism in this embodiment is a "switch" that realizes the quick switching of the tibialis anterior muscle training and the lower leg / forefoot training two modes.

[0047] The mechanism is composed of a rotating seat 32 on the main cross beam 2, a rotating shaft 33, a limiting handle 14, and a clamping rod 15 on the main connecting frame 3. Its working mode is clear and explicit:

[0048] Locking mode for tibialis anterior muscle training: the user operates the limiting handle 14 to make it firmly clamped with the clamping rod 15. At this time, the leg bag mechanism and the main frame mechanism form a rigid whole, and the leg bag mechanism is completely fixed, providing a solid reaction point for tibialis anterior muscle training.

[0049] Unlocking mode for lower leg and forefoot training: the user reverses the operation of the limiting handle 14 to make it disengage with the clamping rod 15. At this time, the entire leg bag mechanism restores the freedom of rotation up and down around its own connecting shaft, and becomes a movable load with adjustable weight that can be lifted by the user through the foot pedal action.

[0050] In summary, the present application integrates three different lower limb training functions in one through the precise cooperation of the four parts. The user only needs to perform simple locking and unlocking and angle weight adjustment to complete comprehensive and efficient lower limb muscle group comprehensive training on the same device.

[0051] Working principle: the working principle of the trainer is that after the user sits on the cushion 7 fixed on the main connecting frame 3, the height adjusting pipe 30 is slid in the leg bag group fixing pipe 8 through the height adjusting locking device 19, the rotatable locking leg bag 20 is adjusted to the position of pressing the thigh, and the angle between the rotatable locking leg bag 20 and the thigh of the user can be freely adjusted to ensure that the rotatable locking leg bag 20 can always adhere to the thigh of the trainer to ensure stability during the training; then the initial angle of the foot pedal 9 is set by operating the limiting handle 14 matched with the angle adjusting gear 11; when the tibialis anterior muscle and the front of the foot and the ankle of the back of the foot are trained, the main connecting frame 3 is locked on the main cross beam 2 by rotating the rotating shaft 33 in the rotating seat 32 to drive the limiting handle 14 to be clamped with the clamping rod 15, the user hooks upward the foot pedal 9 supported by the foot sleeve 12 to make it rotate upward around the bearing group 13, and the weight of the counterweight piece hanging rod 10 on the foot pedal 9 or the resistance of the elastic band connected between the elastic band hook 16 and the counterweight hook two 17 and the counterweight hook three 18 are overcome; when the calf muscle group is trained, the limiting handle 14 and the clamping rod 15 are unlocked, the user steps down the foot pedal 9, at this time the thigh exerts force upward to overcome and lift the whole weight of the unlocked leg bag mechanism, and the weight can be increased through the counterweight piece hanging rod 10 or the counterweight hook three 18 on the main connecting frame 3.

[0052] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
