Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology, and in particular to a seated incline chest press trainer. Background Technology

[0002] The incline bench press is a popular strength training machine in gyms, effectively working the user's arm and chest muscles to sculpt a strong upper body. A standard incline bench press typically consists of the following main parts: a seat for comfortable and safe support; a backrest to ensure good support during training; a frame to provide stability; weights to allow users to choose appropriate weights based on their abilities; and a pair of movable chest-pressing arms for gripping to perform the pressing motion.

[0003] When using the incline bench press machine, first adjust the position of the seat and backrest to ensure the body is comfortably and stably positioned on the machine. Then, grip the handles on the chest press arms firmly with both hands, and using the coordinated effort of your arms and chest muscles, push the chest press arms upwards and forwards to complete one full press movement. At the top of the press, the muscles should be fully contracted. Pause briefly, then slowly return the chest press arms to the starting position to begin the next repetition.

[0004] However, some existing incline press machines have certain limitations in their design. Because each user's size and strength level are different, some users with relatively weaker strength often find it difficult to overcome the initial resistance, resulting in an inability to smoothly push the chest press arms, and potentially even causing sports injuries. While some incline press machines have emerged that can assist in lifting the chest press arms, their structural design is not yet optimal, their transmission mechanisms are complex, and there is significant wear and tear between components.

[0026] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0028] like Figure 1-7As shown, this embodiment provides a seated incline chest press trainer 1, including a vertical frame 10. A swing arm assembly 20 is pivotally connected to the vertical frame 10. In this embodiment, the swing arm assembly 20 is pivotally connected to the vertical frame 10 via a swing arm pivot shaft 23. A seat and backrest assembly 30 is also installed on the vertical frame 10. The seat and backrest assembly 30 includes a seat cushion 31 and a backrest cushion 32, and is used to provide comfortable and safe support for the user. A limiting member 40 is also pivotally connected to the vertical frame 10. In this embodiment, the limiting member 40 is pivotally connected to the vertical frame 10 via a limiting member pivot shaft 41. The movable end 402 of the limiting member 40 is provided with a roller 42, which is located below the swing arm assembly 20. The limiting member 40 can be pushed and pivoted around the limiting member pivot axis 41, so that the roller 42 contacts the swing arm assembly 20 and lifts the swing arm assembly 20, realizing the "lifting bar" function in the seated incline chest press trainer 1. This makes it easier for users with relatively weak strength to overcome the resistance in the initial stage, smoothly push the swing arm assembly, and reduce sports injuries.

[0029] The roller 42 is pivotally connected to the limiting member 40, so that the friction between the components is minimized during the process of the roller 42 contacting and lifting the swing arm assembly 20. The transmission of this structure is also smoother, greatly reducing wear on the equipment, with low overall cost, high cost performance, and convenient after-sales service and maintenance.

[0030] The seated incline chest press trainer 1 also includes a transmission component 50, which is connected to a limiting member 40. The transmission component 50 can drive the limiting member 40 to move, so that the limiting member 40 pivots around the limiting member pivot axis 41.

[0031] The transmission assembly 50 includes a pivot shaft 52 pivotally mounted on the upright frame 10. A foot pedal 53 and a swing rod 54 are fixedly connected to the pivot shaft 52 in the circumferential direction. The swing rod 54 is connected to one end of a connecting rod 51 through a first joint 55. The other end of the connecting rod 51 is connected to a limiting member 40 through a second joint 56. In this embodiment, both the first joint 55 and the second joint 56 are universal joints, making the joint movement more flexible.

[0032] In use, by stepping on the foot pedal 53, the rotating shaft 52 rotates around its axis, causing the swing rod 54 to swing. The swing rod 54 drives the connecting rod 51 to move through the first joint 55. The connecting rod 51 drives the limiting member 40 through the second joint 56, causing the limiting member 40 to pivot around the limiting member pivot shaft 41. The limiting member 40 drives the roller 42 to contact the swing arm assembly 20 and lift the swing arm assembly 20, so that the user can smoothly push the swing arm assembly 20.

[0033] In this embodiment, the outer peripheral surface 421 of the roller 42 is concave, which allows for a larger contact area with the swing arm assembly 20, thereby further reducing wear between components; and it is also more conducive to the positioning of the swing arm assembly 20 on the roller 42, improving the fitting accuracy between components.

[0034] Reference Figure 1-3 Key reference Figure 3 The limiting member 40 has a pivot end 401 and a movable end 402. The pivot end 41 of the limiting member 40 is located at the pivot end 401, and the roller 42 is located at the movable end 402. The limiting member 40 also has a connecting part 45 for connecting with the second joint 56. The connecting part 45 is located between the pivot end 401 and the movable end 402, so that the displacement movement of the connecting rod 51 can drive the roller 42 of the movable end 402 to produce a greater displacement, making the working stroke of the limiting member 40 assisting in lifting the swing arm assembly 20 longer and providing a better assistive effect for the user.

[0035] The swing arm assembly 20 includes a swing arm body 21 and a handle 22 connected to the swing arm body 21. During exercise, the user can hold the handle 22 to push the swing arm assembly 20. A counterweight mechanism is also connected to the swing arm body 21. In this embodiment, the counterweight mechanism is a counterweight plate hanger 23 provided on the swing arm body 21. The counterweight plate hanger 23 can be used to hang counterweight plates, such as barbell plates. Furthermore, the counterweight plate hanger 23 is not limited to one; at least one counterweight plate hanger 23 can be connected to each swing arm body 21, and different numbers of counterweight plates can be hung on the counterweight plate hanger 23 to generate different resistance levels, thus adapting to users with different exercise needs and providing a wider range of adaptability.

[0036] Furthermore, the upright frame 10 is provided with storage hanging rods 11 for storing counterweight pieces. In this embodiment, there are four storage hanging rods 11, all located on the back side of the upright frame 10. Unused counterweight pieces can be stored in the storage hanging rods 11, making the overall structure more compact and aesthetically pleasing.

[0037] The frame 10 is also provided with a limiting block 12, which is used to abut against the end of the swing rod 54, thereby limiting the rotational stroke of the swing rod 54 and making it more convenient to use.

[0038] Reference Figure 1 , 3 A cylinder assembly 56 is connected between the outer peripheral surface of the rotating shaft 52 and the vertical frame 10. The two ends of the cylinder assembly 56 are respectively hinged to the outer peripheral surface of the rotating shaft 52 and the vertical frame 10. The cylinder assembly 56 can extend and retract and generate resistance, thereby making the rotation of the rotating shaft 52 more stable and preventing the swing arm assembly 20 from falling rapidly, thus improving the safety of the device.

[0039] Reference Figures 1-2 In this embodiment, an adjusting cylinder 311 is connected to the lower part of the seat cushion 31. The adjusting cylinder 311 is used to adjust the height of the seat cushion 31 so that the seat cushion 31 can be adapted to users of different body sizes. An adjusting rod 312 is also connected to the lower part of the seat cushion 31, and an adjusting cylinder 13 is installed on the upright frame 10. The adjusting rod 312 and the adjusting cylinder 13 slide together, thereby playing a guiding role when the height of the seat cushion 31 is adjusted, making the seat cushion 31 more stable when adjusting its height.

[0040] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
