Abstract
Description
Technical Field
[0001] This utility model relates to a fitness equipment, and more particularly to a fitness torque device. Background Technology
[0002] There are many types of fitness equipment, but very few are specifically designed for wrist training. Grip strengtheners are mainly used for training the fingers and wrists, and their intensity is relatively high, so they may not be suitable for all trainees.
[0003] The Chinese patent document publication number is CN2385751Y, and the patent title is "A Simple Torque Device." It consists of two handles, each connected to an elastic rubber rod, and an outer positioning sleeve. Each end of the sleeve has a stop cup screwed on, allowing the rubber rod to rotate only radially within the sleeve, while its axial rotation is limited. The user grips the two handles and rotates the rubber rod to achieve the training purpose. The problem is that rotation in one direction requires effort, while rotation in the opposite direction requires no effort, resulting in a less than ideal training effect. Furthermore, the rapid rebound could potentially injure the user.
[0004] The torque of the elastic rubber rod in the aforementioned torque converter is non-linear and cannot fully express a specific value. Furthermore, the elastic rubber rod tends to harden after a period of use, making it prone to breakage, thus affecting its usability. Summary of the Invention
[0005] This invention addresses the numerous shortcomings of existing torque devices, particularly those using elastic rubber rods, such as: providing resistance only in one direction with no training effect in the reverse direction; the elastomer being prone to aging and hardening, posing a risk of sudden breakage; non-linear torque that cannot be intuitively and accurately displayed; and the safety hazard of rapid rebound leading to injury. The present invention aims to provide a fitness torque device that overcomes these drawbacks.
[0006] The technical solution adopted by this utility model to solve its technical problem is: a fitness torque device, including a first connecting body, an indicator part, a display part, a middle part, a second connecting body, a protrusion, a spindle, and an elastic body. The key features are: the first connecting body and the second connecting body are rotatably fixed to both ends of the spindle; an indicator part is provided between the first connecting body and the second connecting body, and the indicator part is fixedly connected to the first connecting body; a display part with scales is provided between the indicator part and the second connecting body; a pointer is provided on the indicator part for indicating the scales on the display part; and an elastic body is also provided between the first connecting body and the second connecting body, with a middle part on its outer surface.
[0007] Preferably, the first connector, the middle part, the second connector, the spindle, and the elastic body are aligned with the same center line, ensuring uniform force distribution and smooth movement.
[0008] Furthermore, the first connector and the second connector are respectively provided with anti-slip protrusions, and soft rubber is provided on the protrusions to enhance grip comfort and safety.
[0009] Furthermore, the elastomer is preferably a torsion spring. Torsion springs provide linear, predictable torque, stable performance, and a long lifespan.
[0010] In addition, the outer diameter of the elastic body is smaller than the inner diameter of the middle part, which provides sufficient space for the deformation of the elastic body, avoids interference, and ensures smooth operation and accurate force value.
[0011] The beneficial effects of this utility model are: Compared with the prior art, the fitness torque device provided by this utility model has the following significant advantages: First, bidirectional resistance training: Due to the use of elastic elements such as torsion springs, continuous and linear resistance can be provided in both the forward and reverse directions, making wrist training more comprehensive and efficient.
[0012] Secondly, the training is quantified and intuitive: Through the combination of pointer and dial, the user's twisting angle and force value can be clearly and intuitively displayed, realizing the quantitative management of training and making it easy for users to grasp the training intensity and progress.
[0013] Third, it is safe, reliable, and has a long service life: As an elastic body, torsion springs have stable mechanical properties and strong fatigue resistance. Unlike rubber, they are not prone to brittle fracture due to aging, which fundamentally eliminates the risk of sudden breakage. At the same time, the linear restoring force also avoids the situation of rapid rebound causing injury, making it highly safe.
[0014] Fourth, the structure is reasonable and the user is comfortable: The coaxial design ensures smooth operation; the raised part with soft rubber provides excellent anti-slip and grip feel, improving the user experience. Attached Figure Description

[0019] The following is combined Figure 1-3The following description, in conjunction with the accompanying drawings of the embodiments of this utility model, will clearly and completely describe the technical solutions of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0020] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0021] This invention provides a fitness torque device, mainly used for safe, effective and quantifiable torsional strength training of the wrist.
[0022] The fitness torque generator includes a first connector 1, an indicator 2, a display 3, a middle part 4, a second connector 5, a protrusion 6, a spindle 7, and an elastic body 8.
[0023] The mandrel 7 serves as the central support shaft of the entire device. The first connecting body 1 and the second connecting body 5 are rotatably fixed to both ends of the mandrel 7 via conventional rotary connections such as bearings or bushings. The user can grasp the first connecting body 1 and the second connecting body 5 with both hands and apply relative torsional forces.
[0024] An indicator 2 is provided between the first connector 1 and the second connector 5. The indicator 2 is fixedly connected to the first connector 1 by means of key connection, screw fixation or integral molding, so that the indicator 2 can rotate synchronously with the first connector 1.
[0025] A display section 3 is provided between the indicator section 2 and the second connecting body 5. The display section 3 is preferably a fixed annular component, which can be fixed to the middle section 4 or the spindle 7 by means of a connector (such as a bracket). The side of the display section 3 facing the indicator section 2 is printed with scales to indicate the angle of torsion and / or the force value.
[0026] The indicator 2 is equipped with a pointer (not shown separately in the figure). This pointer can be a protrusion on the edge of the indicator 2 or a separately installed indicator rod. When the first connecting body 1 rotates relative to the second connecting body 5, the indicator 2 and its pointer fixed to the first connecting body 1 will rotate accordingly, thereby indicating the corresponding value on the dial of the stationary display 3.
[0027] An elastic body 8 is also provided between the first connecting body 1 and the second connecting body 5. In this embodiment, the elastic body 8 is preferably a torsion spring. The torsion spring is sleeved outside the spindle 7, with one end fixed to the first connecting body 1 or a component fixedly connected to the first connecting body 1 (such as the indicator part 2), and the other end fixed to the second connecting body 5 or a component fixedly connected to the second connecting body 5. When the first connecting body 1 and the second connecting body 5 rotate relative to each other, the torsion spring is forced to undergo torsional deformation, thereby generating a linear restoring force that resists torsion and provides resistance for training.
[0028] The elastic body 8 is provided with the intermediate portion 4 on its exterior. The intermediate portion 4 can be a cylindrical shell, the main function of which is to protect the internal elastic body 8 and indicating mechanism, preventing dust intrusion and accidental contact by the user. The outer diameter of the elastic body 8 is smaller than the inner diameter of the intermediate portion 4, ensuring that the elastic body 8 has sufficient space during torsional deformation, preventing friction or interference with the intermediate portion 4, and ensuring smooth operation and accurate force values.
[0029] Furthermore, the first connecting body 1, the intermediate part 4, the second connecting body 5, the spindle 7, and the elastic body 8 are all aligned with the same center line. This coaxial design ensures uniform force distribution and smooth movement, avoiding additional wear and vibration caused by eccentricity.
[0030] In a preferred embodiment, the first connector 1 and the second connector 5 are each provided with protrusions 6. These protrusions 6 can be granular, striped, or wavy, which increase the friction between the user's hand and the connector, effectively preventing slippage and ensuring the hand stays in place when twisted forcefully. More preferably, a layer of soft rubber (such as silicone or TPU) is coated or injection-molded onto the protrusions 6, which further enhances grip comfort and improves the anti-slip effect.
[0031] Working principle: The user holds the protrusions 6 on the first connector 1 and the second connector 5 with both hands. During wrist training, one hand (corresponding to the second connector 5) remains relatively still while the other hand (corresponding to the first connector 1) applies a torsional force. The first connector 1 rotates along with the indicator 2, thereby compressing or stretching the elastic body 8 (torsion spring) between it and the second connector 5. The linear restoring force generated by the elastic body 8 counteracts the user's torsional force, achieving the training objective. Simultaneously, as the indicator 2 rotates, its pointer moves on the scale of the display 3, allowing the user to visually read the angle of torsion and determine the applied force value through a preset correspondence between the scale and the force value, thus achieving quantitative training.
[0032] Compared to existing products mentioned in the background section, this invention utilizes a torsion spring as the elastic body 8, resulting in a linear force change, a better training experience, and increased safety due to the reduced risk of sudden breakage caused by material aging. Furthermore, the combination of a pointer and a dial clearly displays the training intensity, solving the problem of existing technologies being unable to fully express specific numerical values. In addition, because the torsion spring provides resistance in both directions of rotation, the training process involves bidirectional force application, avoiding the shortcomings of unidirectional force application and lack of resistance in the reverse direction, resulting in a more comprehensive training effect and preventing the risk of injury from rapid rebound.
[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
