Abstract
Description
Technical Field
[0001] This utility model relates to the field of fitness equipment technology, specifically, to a handle adjustment mechanism for a fly trainer and a fly trainer. Background Technology
[0002] As a common chest and shoulder training device, the fly trainer's core function is to help users strengthen muscle groups such as the pectoralis major and deltoids by simulating the wing-spreading motion of a bird. Currently, fly trainer handles on the market usually only support adjustment in one direction, such as only moving forward and backward or rotating around the handle axis. They cannot adjust the tilt angle of the handle relative to the sagittal plane of the human body. This forces users to frequently change equipment or forcibly adapt to a fixed angle when performing different training movements (such as standing flyes and bent-over flyes), increasing the complexity of operation and making it easy to cause sports injuries due to improper training posture.
[0003] Therefore, there is an urgent need to develop a handle adjustment mechanism for a bird trainer that can be adjusted at multiple angles to meet different training needs. Utility Model Content
[0004] This utility model provides a handle adjustment mechanism for a bird trainer and a bird trainer, so as to at least solve the problems of the existing handle adjustment mechanism of the bird trainer having a single adjustment direction and limited training effect.
[0005] To achieve the above objectives, this utility model provides a handle adjustment mechanism for a flight trainer. The flight trainer includes two swing arms symmetrically connected to the main frame in a swingable manner relative to the main frame. The operating ends of both swing arms are provided with the handle adjustment mechanism, which includes:
[0006] The handle is rotatably connected to the operating end of the swing arm, and the handle is at a constant tilt angle relative to the coronal plane of the human body.
[0007] A limiting plate is fixedly connected to the handle, and the limiting plate is provided with a plurality of limiting holes spaced apart along the circumference;
[0008] Telescopic plugs are fixedly connected to the swing arm. The telescopic end of each telescopic plug is inserted into one of the limiting holes on the corresponding limiting plate to lock the rotation angle of the handle. Pulling out the telescopic plug can disengage the telescopic end from the limiting hole, realizing multi-angle adjustment of the handle relative to the human sagittal plane to adapt to different training movement needs.
[0009] Furthermore, the limiting plate has at least a first limiting hole and a second limiting hole;
[0010] When the telescopic plug is inserted into the first limiting hole, the handle is tilted inward relative to the sagittal plane of the human body to form a first training angle to adapt to bent-over bird training.
[0011] When the telescopic plug is inserted into the second limiting hole, the handle is tilted outward relative to the sagittal plane of the human body to form a second training angle to adapt to standing bird flight training.
[0012] Furthermore, the telescopic plug includes:
[0013] A pin sleeve is fixedly connected to the swing arm;
[0014] A pin slides through the pin sleeve along the axial direction, and its insertion end is inserted into one of the limiting holes on the limiting plate.
[0015] Furthermore, the telescopic plug-in also includes:
[0016] An elastic element is disposed in the inner cavity of the pin sleeve. The insertion end of the pin is provided with a first locking platform, and the inner wall of the pin sleeve is provided with a second locking platform. One end of the elastic element abuts against the first locking platform, and the other end abuts against the second locking platform, for applying an elastic restoring force toward the limiting hole to the pin.
[0017] Furthermore, the operating end of the pin has an operating end cover.
[0018] Furthermore, the pin sleeve is fixedly connected to the swing arm via a fixing sleeve.
[0019] Furthermore, the inner cavity of the fixed sleeve is provided with a bearing, and the handle is inserted into the inner cavity of the fixed sleeve through a rotating shaft and connected to the swing arm through the bearing.
[0020] Furthermore, the watch face is covered with a non-slip silicone layer.
[0021] Furthermore, the handle adjustment mechanism is detachably mounted on the operating end of the swing arm.
[0022] This utility model provides a bird training device that uses the handle adjustment mechanism described above.
[0023] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0024] This invention allows users to quickly adjust the tilt angle of the handle relative to the sagittal plane of the human body through the cooperation of multiple circumferential limiting holes on the limiting plate and telescopic plugs. This allows for precise adaptation to different training movements such as standing fly and bent-over fly, without the need to change equipment or force adaptation to a fixed angle, thus significantly improving training efficiency and movement diversity.
[0025] This invention's handle angle adjustment mechanism makes training movements more ergonomic. For example, during bent-over fly exercises, the handle is tilted inward at a small angle relative to the sagittal plane of the body, matching the forward-leaning posture of the torso and reducing the risk of shoulder impingement. During standing fly exercises, the handle is tilted outward relative to the sagittal plane of the body to avoid excessive shoulder abduction. By adjusting the handle angle to optimize the force line direction, the load on the shoulder joint and surrounding soft tissues is effectively reduced, ensuring training safety.

[0036] 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 of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0037] Currently available fly trainer handles typically only support single-directional adjustment, such as movement only in the forward / backward direction or rotation around the handle axis. This forces users to frequently change equipment or force themselves to adapt to a fixed angle when performing different training movements, increasing operational complexity and increasing the risk of sports injuries due to improper training posture. To address these issues, this invention provides a handle adjustment mechanism for fly trainers that allows for multi-angle adjustment relative to the sagittal plane of the human body.
[0038] In human anatomy, the sagittal plane is a longitudinal plane perpendicular to the ground, dividing the human body into left and right parts. The plane perpendicular to the sagittal plane is called the coronal plane, while the plane parallel to the ground is called the transverse plane. The sagittal plane is an important reference plane for describing the direction of human movement and posture. In the handle adjustment mechanism of this invention, the human sagittal plane serves as the core reference plane, used to illustrate the state of the adjustable handle mechanism when adapting to different training needs.
[0039] like Figures 1-4As shown, this utility model provides a handle adjustment mechanism for a bird trainer. The bird trainer includes two swing arms 2, which are symmetrically connected to the main frame 1 in a swingable manner relative to the main frame 1. The operating ends of the two swing arms 2 are provided with handle adjustment mechanisms. The handle adjustment mechanism includes: handle 3, limit plate 4, and telescopic plug 5.
[0040] The handle 3 is rotatably connected to the operating end of the swing arm 2 and the handle 3 is at a constant tilt angle relative to the coronal plane of the human body.
[0041] The limiting disc 4 is sleeved and fixed to the rotating shaft, and the limiting disc 4 is provided with a plurality of limiting holes 41 distributed circumferentially;
[0042] The telescopic plug 5 is fixedly connected to the swing arm 2. The telescopic end of the telescopic plug 5 is inserted into one of the limiting holes 41 on the corresponding limiting plate 4 to lock the rotation angle of the handle 3. Pulling out the telescopic plug 5 can make the telescopic end disengage from the limiting hole 41, so as to realize the multi-angle adjustment of the handle 3 relative to the sagittal plane of the human body to adapt to different training movement needs.
[0043] In some embodiments, the handle 3 maintains a relatively constant tilt angle relative to the coronal plane of the human body during adjustment. This tilt angle can be an obtuse angle of 125°. This tilt angle allows the wrist, located on the front side of the body, to be in a natural gripping state when the trainee abducts the arm, avoiding excessive pressure on the wrist and reducing the risk of sports injury to the trainee.
[0044] Preferably, such as Figure 2 and Figure 4 As shown, the limiting plate 4 has at least a first limiting hole and a second limiting hole.
[0045] Figure 2 This is a schematic diagram of the first state structure of the handle 3 training mechanism of this utility model, as shown below. Figure 2 As shown, when the telescopic plug 5 is inserted into the first limiting hole, the handle 3 tilts inward relative to the sagittal plane of the human body to form the first training angle, so as to adapt to the bent-over bird training.
[0046] In some embodiments, when the telescopic plug 5 is inserted into the first limiting hole, the handle 3 is in a first state. At this time, the handle 3 is tilted inward relative to the sagittal plane of the human body, forming a first training angle. The first training angle can be 8°-12°, suitable for bent-over fly training. Specifically, when the user performs bent-over fly training, the body leans forward, and the arms extend downward and outward. At this time, the inward tilt angle of the handle 3 is designed to conform to the natural movement trajectory of the human body, enabling the trainee to maintain a relatively comfortable and stable posture during training, reducing body twisting or overextension caused by an unsuitable angle of the handle 3, thereby effectively reducing pressure on the shoulder joint and other parts, and reducing the risk of injury. At the same time, this angle design also helps to better activate and exercise target muscle groups, such as back muscles, and improve training effects.
[0047] Figure 4 This is a schematic diagram of the second state structure of the handle 3 training mechanism of this utility model, as shown below. Figure 4 As shown, when the telescopic plug 5 is inserted into the second limiting hole, the handle 3 tilts outward relative to the sagittal plane of the human body, forming a second training angle to adapt to standing bird flight training.
[0048] In some embodiments, when the telescopic plug 5 is inserted into the second limiting hole, the handle 3 is in a second state. At this time, the handle 3 is tilted outward relative to the sagittal plane of the human body, forming a second training angle. The second training angle can be 25°-30°, suitable for standing fly training. Specifically, during standing fly training, the trainee stands upright with arms extended to the sides. The outward tilt angle of the handle 3 fully considers the range of motion and bearing capacity of the shoulder joint, avoiding excessive stretching or rotation of the shoulder due to an excessively extreme angle of the handle 3 during training, thereby reducing the possibility of shoulder injury. Furthermore, this angle of the handle 3 allows the user to use the strength of the arms and shoulders more naturally during training, maintaining body balance and stability. It also helps to better stimulate and exercise target muscle groups such as the chest and shoulders, enhancing muscle strength and endurance, and improving the overall safety and effectiveness of training.
[0049] Preferably, such as Figures 5-6 As shown, the telescopic plug 5 includes a pin sleeve 51, a pin 52, and an elastic element 53.
[0050] The pin sleeve 51 is fixedly connected to the swing arm 2;
[0051] The pin 52 slides through the pin sleeve 51 along the axial direction and is inserted into one of the limiting holes 41 on the limiting plate 4.
[0052] The elastic element 53 is disposed in the inner cavity of the pin sleeve 51, with one end abutting against the pin 52 and the other end abutting against the inner wall of the pin sleeve 51, for applying an elastic restoring force toward the limiting hole 41 to the pin 52.
[0053] In some embodiments, when the trainee needs to adjust the angle of the handle 3, an external force is applied to pull the pin 52 out of the limiting hole 41. At this time, the elastic element 53 is compressed, generating elastic potential energy. Once the pin 52 is pulled out, the trainee can rotate the handle 3 and the limiting plate 4 according to the training needs, so that the pin 52 is aligned with the required limiting hole 41. When the external force is released, the elastic restoring force of the elastic element 53 pushes the pin 52 back into the corresponding limiting hole 41, thereby fixing the handle 3 in a new angular position. The telescopic plug 5 is easy to operate and can ensure that the handle 3 remains stable during training, avoiding a decrease in training effect or user injury due to the loosening of the handle 3.
[0054] Preferably, the insertion end of the pin 52 is provided with a first locking platform, the inner wall of the pin sleeve 51 is provided with a second locking platform, and the elastic element 53 is a compression spring. The compression spring is sleeved on the pin 52, with one end abutting against the first locking platform and the other end abutting against the second locking platform.
[0055] Preferably, the operating end of the pin 52 has an operating end cap. The trainee can grip the pin 52 more firmly through the operating end cap, preventing fingers from slipping and ensuring that the pin 52 can be pulled out smoothly.
[0056] Preferably, the pin sleeve 51 is fixedly connected to the swing arm 2 by the fixing sleeve 6.
[0057] In some embodiments, the fixing sleeve 6 is fixedly connected to the swing arm 2 by welding, and the fixing sleeve 6 has a protruding fixing plate, through which the pin sleeve 51 is fixedly connected to the swing arm 2. This ensures the stability of the pin sleeve 51 during use.
[0058] Preferably, the inner cavity of the fixed sleeve 6 is provided with a bearing 7, and the handle 3 is inserted into the inner cavity of the fixed sleeve 6 through a rotating shaft and connected to the swing arm 2 through the bearing 7.
[0059] In some embodiments, the connection via bearing 7 allows the rotating shaft to rotate smoothly relative to the swing arm 2, reducing friction and wear and improving the service life and reliability of the bird trainer. Bearing 7 can also withstand certain radial and axial loads, ensuring the stability and safety of the handle 3 during training.
[0060] Preferably, the surface of the handle 3 is covered with an anti-slip silicone layer. The anti-slip silicone layer can increase the friction between the handle 3 and the trainee's hand, effectively preventing the hand from slipping during training, ensuring that the trainee can firmly grip the handle, and improving the safety of training.
[0061] Preferably, the handle adjustment mechanism is detachably disposed at the operating end of the swing arm.
[0062] In some embodiments, during equipment maintenance, when the handle adjustment mechanism is worn or malfunctions, it is not necessary to inspect the entire bird trainer; only the malfunctioning handle adjustment mechanism needs to be disassembled for individual repair or replacement, which greatly shortens maintenance time and reduces maintenance costs.
[0063] In some embodiments, the outer edge of the limiting disc 4 is marked with various limiting holes 41. When adjusting the handle angle, the trainee can intuitively and quickly determine the required angle based on the markings, thus improving training efficiency.
[0064] In some embodiments, the handle 3 adjustment mechanism provided by this utility model is used in the following ways:
[0065] The trainee stands on the training pedal or training area of the fly trainer and selects the training mode.
[0066] If a bent-over bird training is required, the trainee can pull out the pin 52 by operating the end cover, rotate the handle 3 and the limit plate 4 to align the pin 52 with the first limit hole, release the pin 52, and the compressed spring will give the pin 52 an elastic restoring force, so that it will automatically insert into the first limit hole, complete the angle locking of the handle 3, and enter the bent-over bird training mode.
[0067] If standing bird-flying training is required, the trainee can pull out the pin 52 by operating the end cover, rotate the handle 3 and the limit plate 4 to align the pin 52 with the second limit hole, release the pin 52, and the compressed spring will give the pin 52 an elastic restoring force, so that it will automatically insert into the second limit hole, complete the angle locking of the handle 3, and enter the standing bird-flying training mode.
[0068] If there are other training needs, select the corresponding limit hole 41 to adjust the angle of handle 3 according to the needs.
[0069] This utility model provides a bird training device that uses the handle adjustment mechanism described above.
[0070] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
