DETAILED DESCRIPTION

[0027] Example 1

[0028] like Figures 1-10 As shown, a multifunctional biceps trainer proposed in this embodiment includes a support frame 1, a support pad assembly, a seat cushion assembly, a pedal assembly and a gear adjustment mechanism.

[0029] The support pad assembly is arranged on the upper part of the support frame 1, and the support pad assembly is used to support the user's upper arm or elbow, so that the user's arm can exercise the biceps through the gear adjustment mechanism.

[0030] The seat cushion assembly is arranged on the support frame 1 and is lower than the height of the support cushion assembly, and the user can sit on the seat cushion assembly to exercise.

[0031] Two groups of pedal assemblies are symmetrically arranged at the lower part of the support frame 1, and the user can stand on the two groups of pedal assemblies to exercise.

[0032] like Figure 4-Figure 6As shown, the gear adjustment mechanism is symmetrically arranged in two groups about the support frame 1. The gear adjustment mechanism includes a barbell arm 2 rotatably mounted on the support frame 1, a barbell sleeve 3 mounted at the front end of the barbell arm 2, a fixed cylinder 7 mounted on the support frame 1, a rotating shaft 6 rotatably mounted on the fixed cylinder 7, a connecting disk 5 mounted at the outer end of the rotating shaft 6, a connecting belt 4 connected between the barbell arm 2 and the connecting disk 5, a positioning cylinder 8 mounted on the rotating shaft 6, a chuck 10 mounted on the positioning cylinder 8 and having a plurality of fan-shaped sockets 101, a rotating arm 9 rotatably mounted on the rotating shaft 6, a gear adjustment assembly mounted on the rotating arm 9 and capable of adjusting the gear position by adjusting the different sockets 101, and an adjustable handle assembly mounted at the outer end of the rotating arm 9. Barbell plates can be mounted on the barbell sleeve 3, and users can mount barbell plates of different weights according to their desired exercise intensity. When the user is exercising, the upper arm or elbow is supported on the support pad assembly, the hand is facing upward to hold the adjustable grip assembly, and the adjustable grip assembly is lifted upward. The adjustable grip assembly drives the rotating arm 9 to rotate, and the rotating arm 9 drives the chuck 10, the positioning cylinder 8 and the rotating shaft 6 to rotate through the gear adjustment assembly. The rotating shaft 6 drives the barbell arm 2 to rotate through the connecting plate 5 and the connecting belt 4, and the barbell plate mounted on the barbell sleeve 3 is lifted to achieve weight-bearing exercise.

[0033] The gear adjustment assembly is adjustable to adjust the range of motion of the user's arm exercise. The gear adjustment assembly includes a connecting plate 11 mounted on the rotating arm 9, a connecting tube 12 mounted on the connecting plate 11, a sliding post 14 slidably mounted within the connecting tube 12 and having an inclined push slot 141, an end plate 13 mounted at one end of the connecting tube 12, a compression spring 15 connected between the sliding post 14 and the end plate 13, a sleeve 16 mounted on the connecting tube 12, and a pressing rod 17 slidably mounted on the sleeve 16 and configured to remove the end of the sliding post 14 from the insertion hole 101 by pushing the push slot 141. When adjusting the gear, the user holds the sleeve 16 and presses the pressing rod 17. The end of the pressing rod 17 moves in the pushing groove 141, pushing the slide 14 outward. The slide 14 compresses the compression spring 15, and the slide 14 moves out of the socket 101. The user rotates the sleeve 16, keeping the pressing rod 17 in the pressed state, and aligns the end of the slide 14 with the socket 101 in another direction. Then, the pressing rod 17 is released. The compression spring 15 pushes the slide 14 to move. The slide 14 is inserted into the socket 101 to limit the position, and the rotating arm 9 and the positioning cylinder 8 are linked. The lower the socket 101 is inserted by the slide 14, the lower the initial position of the adjustable grip assembly, and the greater the range of arm movement of the user when holding the adjustable grip.

[0034] like Figure 1 As shown, a gear plate 34 is provided on the chuck 10, and the gear plate 34 has multiple gear holes corresponding to the socket 101. There are five sockets 101 and five gear holes, corresponding to five gears. The lowest gear hole corresponds to the first gear, and the gears are divided into five gears in sequence.

[0035] like Figure 4 and Figure 6 As shown, the adjustable grip assembly includes a mounting tube 18 disposed on the rotating arm 9, a mounting plate 19 disposed on the mounting tube 18, a swing plate 20 rotatably disposed on the mounting plate 19, a grip 21 disposed at the outer end of the swing plate 20, a first guide tube 23 disposed on the mounting plate 19, a first connector 24 connected to the first guide tube 23, a first slide bar 25 slidably disposed on the inner wall of the first guide tube 23, a first pull button 22 connected to the outer end of the first slide bar 25, and a first spring 26 connected between the first slide bar 25 and the first connector 24. The first slide bar 25 has a first protruding ring portion for abutment by the first spring 26. The swing plate 20 has a connecting hole 201 for rotationally connecting to the mounting plate 19 and two insertion holes 202 for switching the insertion position of the first slide bar 25. The orientation of the grip 21 is adjustable to adjust the gripping position of the user's hand. Specifically, there are two adjustment states, corresponding to whether the grip 21 is inclined or parallel to the horizontal plane. Adjustment is achieved by inserting the first slide bar 25 into different insertion holes 202. During adjustment, the first pull button 22 is pulled outward, which drives the first slide bar 25 outward. The end of the first slide bar 25 moves out of one insertion hole 202 and compresses the first spring 26. The handle 21 is rotated, which drives the swing plate 20 to rotate, rotating the other insertion hole 202 to a position aligned with the first slide bar 25. At this time, the first pull button 22 is released, and the first spring 26 pushes the first slide bar 25, and the first slide bar 25 is inserted into the insertion hole 202 at this location.

[0036] like Figure 1 and Figure 2 As shown, support frame 1 is provided with brackets 511 on both sides of its lower portion for supporting barbell arms 2. A retaining frame 512 is provided on connecting plate 5, capable of blocking support frame 1. This allows the user to exercise their biceps by reciprocating the lifting and pulling of handle 21. When the user is not exerting force on handle 21, brackets 511 support barbell arms 2, while retaining retaining frame 1 blocks retaining support frame 1. This limits the range of motion of handle 21, ensuring a balanced and intense biceps workout within the defined range.

[0037] This embodiment allows users to adjust the initial height and orientation of their grip for exercise, allowing for exercises with varying ranges of motion and grip orientations, resulting in more diverse exercise methods and functions. To adjust the initial height of the grip 21, the user inserts the slide 14 into different sockets 101 located in different orientations on the chuck 10. To adjust the orientation of the grip 21, the user inserts the first slide bar 25 into different sockets 202. This simple and convenient operation meets the varying exercise needs of users. When exercising the biceps by gripping and lifting the grip 21 back and forth, the user can hold both grips 21 simultaneously or only one.

[0038] Example 2

[0039] like Figures 1-10 As shown, a multifunctional biceps trainer proposed in this embodiment, compared with embodiment 1, in this embodiment, the support pad assembly includes a support seat 36 rotatably connected to the rotating shaft 6, a support pad 35 arranged on the support seat 36, a slide 37 rotatably arranged at the bottom of the support seat 36, a rotating cylinder 38 rotatably arranged on the support frame 1 and having a channel for the slide 37 to slide, a second guide cylinder 39 arranged on the rotating cylinder 38, a second connecting head 40 connected to the second guide cylinder 39, a second slide rod 42 slidably arranged on the inner wall of the second guide cylinder 39, a second pull button 41 connected to the outer end of the second slide rod 42 and a second spring 43 connected between the second slide rod 42 and the second connecting head 40, the slide rod 37 has a plurality of limiting holes distributed side by side along the length direction for the second slide rod 42 to be inserted, and the second slide rod 42 has an outwardly protruding second convex ring portion for the second spring 43 to abut.

[0040] When exercising the biceps, the user supports their upper arm or elbow on the support pad 35, which serves as a fulcrum for applying force, facilitating reciprocating motion while gripping the handle 21. To adjust the tilt angle of the support pad 35, the second pull button 41 is pulled outward, which in turn pulls the second slide bar 42 outward. The end of the second slide bar 42 moves outward from a stop hole on the slide cylinder 37, compressing the second spring 43. At this point, the support pad 35 is rotated, and the slide cylinder 37 slides within the rotating cylinder 38. When the support pad 35 reaches the desired tilt angle, the second pull button 41 is released, and the second spring 43 pushes the second slide bar 42 to move. The second slide bar 42 then inserts into the stop hole on the slide cylinder 37 at this height, thereby achieving a secure stop.

[0041] The support pad 35 is adjustable in its inclination. When the user is exercising while sitting on the seat assembly, the support pad 35 is adjusted to a smaller inclination angle relative to the horizontal plane, thereby supporting the upper arm or elbow. When the user is exercising while standing on the pedal assembly, the support pad 35 is adjusted to a larger inclination angle relative to the horizontal plane. This is because the user's upper torso is taller, and the support pad 35 with a larger inclination angle can provide more comfortable support for the user's upper arm or elbow.

[0042] like Figure 2 As shown, a handle 52 is provided at the front end of the support seat 36. When the user only exercises the left arm or the right arm, the other hand holds the handle 52, which is conducive to ensuring the user's stable force application and body balance.

[0043] like Figure 1 、 Figure 2 、 Figure 8 and Figure 10 As shown, the seat cushion assembly includes a support column 44 disposed on the support frame 1 and having a plurality of equally spaced slots 441, a seat cushion 50 located on one side of the support column 44, a seat frame 45 disposed at the bottom of the seat cushion 50, two rows of rolling assemblies rotatably disposed on the seat frame 45, an adjustment rod 47 rotatably disposed on the seat frame 45, a clamping column 48 disposed at the end of the adjustment rod 47 and adapted to engage with the slots 441, and a pneumatic rod 49 supported and connected between the support column 44 and the seat frame 45. The rolling assembly includes a plurality of rollers 46 rotatably connected to the support column 44. The two rows of rolling assemblies are located on either side of the support column 44, thereby enabling the seat cushion 50 to be adjusted in height parallel to the support column 44. The support column 44 can be tilted so that when the seat cushion 50 is adjusted upward, it can move below the support pad 35.

[0044] When adjusting the support pad 35, the outer end of the adjustment rod 47 is lifted upward, so that the clamping column 48 moves out of the clamping slot 441 to adjust the height of the seat cushion 50. The roller 46 rolls and rotates on the support column 44. When the seat cushion 50 reaches the desired height, the adjustment rod 47 is pressed downward, and the clamping column 48 is clamped into the corresponding clamping slot 441. The adjustment rod 47 has a tendency to rotate downward at the outer end, and the lever arm at the outer end is longer, which can ensure that the clamping column 48 is stably clamped into the clamping slot 441. When the user needs to sit on the seat cushion 50 for exercise, the seat cushion 50 is adjusted to a suitable position and the pedal assembly is retracted.

[0045] like Figure 7As shown, the pedal assembly includes a swing frame 27 rotatably mounted on the support frame 1, a pedal 28 and an adjustment plate 29 mounted on the swing frame 27, a third guide cylinder 30 mounted on the support frame 1, a third slide bar 32 slidably mounted on the third guide cylinder 30, a third pull button 31 connected to the outer end of the third slide bar 32, a third spring 33 connected between the third slide bar 32 and the third guide cylinder 30, and a stopper 292 mounted on the adjustment plate 29 to limit the rotation range of the pedal 28. The adjustment plate 29 has two latching holes 291 for selectively inserting one end of the third slide bar 32. The pedal 28 has anti-slip protrusions to improve the user's stability when standing.

[0046] When the user needs to perform standing exercise, the seat cushion 50 is removed and the two pedal assemblies are unfolded. To unfold, the third button 31 is pulled outward, which drives the third slide bar 32 outward. The end of the third slide bar 32 moves out of a locking hole 291 on the adjustment plate 29, and the third spring 33 is compressed. The user then unfolds the pedals 28 outward, with the stopper 292 limiting the unfolding range. After the pedals 28 are fully unfolded, the third button 31 is released, and the third spring 33 pushes the third slide bar 32 to move. The end of the third slide bar 32 inserts into another locking hole 291, achieving a stable position and a simple and convenient adjustment method.

[0047] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
