[0029] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0030] like Figures 1-3 As shown, the abdominal exercise device provided in this embodiment includes a main frame assembly 1, which provides overall support for the abdominal exercise device. Specifically, it includes a slide rail bracket 11 and a handrail 4 located at the end of the slide rail bracket 11. A first crossbar 17 is provided at the end of the slide rail bracket 11 away from the handrail 4, and a second crossbar 16 and an adjusting column 15 connected to the second crossbar 16 are provided at the end closer to the handrail 4. The first crossbar 17 and the second crossbar 16 provide overall support for the abdominal exercise device, allowing it to be placed stably on the ground. The connection between the slide rail bracket 11 and the adjusting column 15 allows the height of the slide rail bracket 11 near the handrail 4 to be higher than the other end, enabling the user to perform an abdominal crunch when kneeling on the kneeling mat 32.

[0031] In this embodiment of the utility model, the adjustable column 15 is telescopic, so the height of the slide rail bracket 11 near the handrail 4 can be adjusted by adjusting the length of the adjustable column 15, which can meet the height requirements of different users.

[0032] Furthermore, in this embodiment of the present invention, a slide rail 2 is also provided on the slide rail bracket 11, and a kneeling pad assembly 3 is slidably provided on the slide rail 2. The kneeling pad assembly 3 can slide back and forth along the slide rail 2, and the user can kneel on the kneeling pad 32 and hold the handrail 4 to perform abdominal crunch training.

[0033] In a preferred embodiment of this invention, both the slide rail bracket 11 and the slide rail 2 are metal rod-shaped structures as shown in the attached drawings. These metal rod-shaped structures provide sliding trajectory support for the kneeling pad assembly 3 while minimizing the consumables required for the entire abdominal exercise device, making it lighter and easier for users to drag. It can be understood that, in addition to the rod-shaped structures shown in the attached drawings, the slide rail bracket 11 and the slide rail 2 can also be upwardly protruding or downwardly recessed rod-shaped structures, so that the trajectory of the abdominal crunch movement is not limited to a linear motion.

[0034] Optionally, in some alternative embodiments, one or both of the slide rail support 11 and the slide rail 2 can be configured as flat plate structures to improve the overall stability of the abdominal exerciser. For example, the slide rail support 11 can be configured as a flat plate structure, and the slide rail 2 as a rod-shaped structure. In this case, the adjusting bracket 12 can be an arc-shaped structure embedded in the flat plate structure, or the adjusting bracket 12 and the slide rail support 11 can be configured as a whole, with multiple first connecting seats 13 arranged in an arc shape only at the end of the slide rail support 11. In this case, even if the slide rail 2 has a certain angle with the center position, the slide rail support 11 can balance the gravitational offset caused by the offset of the slide rail 2, making the abdominal exerciser more stable.

[0035] Furthermore, in this embodiment of the present invention, the slide rail 2 is rotatably connected to the slide rail bracket 11, so that the slide rail 2 can rotate in the axial direction on the slide rail bracket 11. An arc-shaped adjustment bracket 12 is provided at the end of the slide rail bracket 11 away from the handrail 4 and / or close to the handrail 4. A plurality of first connecting seats 13 are provided at intervals along the arc-shaped structure of the adjustment bracket 12. The end of the slide rail 2 can be connected to different first connecting seats 13 respectively to adjust the angle between the slide rail 2 and the handrail 4.

[0036] It should be noted that in the first embodiment of the present invention regarding the adjusting bracket 12, the adjusting bracket 12 may be provided only on one side of the slide rail 2, or it may be provided on both sides of the slide rail 2. An example of an embodiment of the present invention is attached. Figure 1-3 As shown, a second connecting seat 14 is provided at the end of the slide rail bracket 11 away from the armrest 4. The slide rail 2 is rotatably connected to the second connecting seat 14. The adjusting bracket 12 is provided at the end of the slide rail bracket 11 near the armrest 4. The arc-shaped structure of the adjusting bracket 12 is set with the second connecting seat 14 as the center. At this time, by connecting the slide rail 2 with different first connecting seats 13 on the adjusting bracket 12, the slide rail 2 can be rotated around the second connecting seat 14, thereby adjusting the angle between the slide rail 2 and the armrest 4. This setting method can adjust the angle of the slide rail 2 to the maximum extent under the same horizontal dimension, making the user's abdominal exercise experience richer.

[0037] like Figure 3 As shown in the specific embodiment of this utility model, five first connecting seats 13 are evenly distributed on the arc-shaped adjusting bracket 12, wherein... Figure 3 (a) shows the angular relationship between slide rail 2 and handrail 4 when slide rail 2 is connected to the leftmost first connecting seat 13. Figure 3 (b) shows the angular relationship between slide rail 2 and handrail 4 when slide rail 2 is connected to the first connecting seat 13 on the left side; Figure 3 (c) shows the angular relationship between slide rail 2 and handrail 4 when slide rail 2 is connected to the first connecting seat 13 on the right side; Figure 3 (d) shows the angular relationship between the slide rail 2 and the handrail 4 when the slide rail 2 is connected to the rightmost first connecting seat 13. Figure 1When the middle slide rail 2 is connected to the first connecting seat 13 in the middle position, the angle relationship between the slide rail 2 and the armrest 4 is such that when the adjustment bracket 12 is evenly distributed with 5 first connecting seats 13, the slide rail 2 has 5 different angle settings, which can then be used to exercise specific muscles in different parts of the abdomen according to the user's needs, thereby improving the user experience.

[0038] In this invention, the end of the slide rail 2 furthest from the handrail 4 is centered with the handrail 4, while the end closer to the handrail 4 can be adjusted according to the user's needs to create an angle between the slide rail 2 and the handrail 4. In other words, this embodiment not only makes the angle between the sliding direction of the slide rail 2 and the extension direction of the handrail 4 different, but also keeps the end of the slide rail 2 closer to the handrail 4 spaced apart from the handrail 4, so that the direction of the user's body movement and the direction of the shoulders form an angle difference, thereby achieving the purpose of exercising different muscle groups in the waist and abdomen.

[0039] Furthermore, in the second embodiment of the present invention regarding the adjusting bracket 12 (not shown in the accompanying drawings), a second connecting seat 14 can be provided in the middle region of the slide rail bracket 11. The slide rail 2 is rotatably connected to the second connecting seat 14. The adjusting bracket 12 is provided at both ends of the slide rail bracket 11. The arc-shaped structures of the adjusting brackets 12 at both ends of the slide rail bracket 11 are symmetrically arranged with the second connecting seat 14 as the center. At this time, by rotating the slide rail 2 on the second connecting seat 14, the two ends of the slide rail 2 correspond to the adjusting brackets 12 on both sides, thereby adjusting the angle between the slide rail 2 and the handrail 4. This arrangement allows the slide rail 2 to be symmetrically distributed along the straight line direction where the handrail 4 and the slide rail bracket 11 are located, which can effectively avoid the problem of gravity instability caused by gravity tilting to one side during movement.

[0040] Understandably, in this embodiment of the present invention, the middle area of ​​the slide rail bracket 11 is not absolutely the exact center of the slide rail bracket. It is only necessary to ensure that the second connecting seat 14 avoids both ends of the slide rail 2. This embodiment can also make the sliding direction of the slide rail 2 different from the extension direction of the armrest 4, and also keep the end of the slide rail 2 near the armrest 4 spaced apart from the armrest 4, so that the direction of the user's body movement and the direction of the shoulder form an angle difference, thereby achieving the purpose of exercising different muscle groups of the waist and abdomen.

[0041] Furthermore, in the third embodiment of the present invention regarding the adjustable bracket 12 (not shown in the accompanying drawings), a second connecting seat 14 can be provided at the end of the slide rail bracket 11 near the armrest 4. The slide rail 2 is rotatably connected to the second connecting seat 14. The adjustable bracket 12 is located at the end of the slide rail bracket 11 away from the armrest 4. The arc-shaped structure of the adjustable bracket 12 is centered on the second connecting seat 14. In this case, by rotating the slide rail 2 on the second connecting seat 14, the end of the slide rail 2 away from the armrest is connected to different positions of the adjustable bracket 12, thereby adjusting the angle between the slide rail 2 and the armrest 4. This embodiment differs from the above two embodiments in that the sliding end of the slide rail 2 converges with the armrest 4 at the same focal point. Although it cannot structurally achieve an angle difference between the user's body movement direction and the shoulder orientation, it can still achieve the purpose of exercising different muscle groups in the waist and abdomen through subsequent optimized embodiments of the present invention.

[0042] This invention allows users to train not only the rectus abdominis muscle in the center of the abdomen, but also the external oblique and internal oblique muscles, by adjusting the angle of the slide rail 2. This ensures that all muscle groups in the core abdominal area are trained, thereby improving the user experience.

[0043] Furthermore, such as Figure 2 As shown in the embodiment of this utility model, the first connecting seat 13 is an adjustment connection hole provided on the adjustment bracket 12. A guide sleeve 22 is provided at one end of the slide rail 2 near the adjustment bracket 12. When the slide rail 2 is connected to the adjustment bracket 12, the guide sleeve 22 is correspondingly arranged with the adjustment connection hole so that the guide sleeve 22 sets a gap between the slide rail 2 and the adjustment bracket 12. Specifically, when the guide sleeve 22 corresponds to the position of an adjustment connection hole, the slide rail 2 is fixed on the adjustment bracket 12 by the detachable knob assembly 23, and the slide rail 2 as a whole maintains a preset distance from the adjustment bracket 12 and the slide rail bracket 11 to provide space for the kneeling pad assembly 3 to slide.

[0044] Furthermore, in this embodiment of the invention, the knob assembly 23 is detachably connected to the slide rail 2. The knob assembly 23 includes a knob at one end and a connecting rod connecting the knob. The connecting rod connects to the guide sleeve 22 and the adjustment connection hole, respectively, so that the slide rail 2 is connected to the adjustment bracket 12. In a preferred embodiment of the invention, the first connecting seat 13 is provided with a threaded hole, and the guide sleeve 22 is also provided with threads. The threads on the connecting rod can connect with the guide sleeve 22 and the first connecting seat 13, thereby strengthening the connection strength of the slide rail 2. The knob of the knob assembly 23 has a certain thickness, and striped grooves are provided around the knob, making it easy for the user to manually rotate the knob to disassemble and connect the knob assembly 23. The diameter of rotation can be the same as or slightly smaller than the width of the slide rail 2, so as to make the operation of the knob easier without affecting the overall width of the slide rail.

[0045] Furthermore, a connecting shaft 21 protruding from the slide rail 2 is provided at the corresponding position of the slide rail 2 and the second connecting seat 14. The second connecting seat 14 is a rotating sleeve 14 protruding from the slide rail bracket 11. The connecting shaft 21 is rotatably connected in the rotating sleeve 14, and the rotating sleeve 14 supports the spaced arrangement between the slide rail 2 and the slide rail bracket 11. The rotating sleeve 14 abuts against the side of the slide rail 2, and together with the guide sleeve 22 at the other end of the slide rail 2, it supports the spaced arrangement between the slide rail 2 and the slide rail, which facilitates the provision of sliding space for the kneeling pad assembly 3.

[0046] In a preferred embodiment of this utility model, the slide rail bracket 11, the adjusting bracket 12, and the rotating sleeve 14 can be a welded metal structure, giving the entire main frame assembly 1 strong support and stability. Alternatively, they can be constructed from other novel materials, as long as the overall structural stability of the abdominal exerciser provided in this embodiment is ensured.

[0047] Furthermore, such as Figures 4-6 As shown, the kneeling pad assembly 3 of this utility model embodiment includes a sliding seat 31 and a kneeling pad 32. The sliding seat 31 is slidably connected to the slide rail 2, and the kneeling pad 32 is connected to the sliding seat 31. When the user kneels on the kneeling pad 32, he / she can slide on the slide rail 2 with the sliding seat 31 to complete the abdominal crunch.

[0048] Furthermore, in a preferred embodiment of this utility model, the kneeling pad 32 and the sliding seat 31 are also rotatably connected, further improving the user's fitness effect.

[0049] In the first embodiment of the kneeling pad assembly 3 of this utility model, a third connecting seat 34 is provided on the sliding seat 31, and a kneeling pad shaft 37 is provided at the position corresponding to the third connecting seat 34 on the kneeling pad 32. The kneeling pad shaft 37 is rotatably connected to the third connecting seat 34 so that the kneeling pad 32 can rotate on the sliding seat 31. A first pin connecting hole 35 is also provided on the sliding seat 31 next to the third connecting seat 34. A plurality of pin holes 38 matching the first pin connecting hole 35 are provided on the kneeling pad 32. The plurality of pin holes 38 are distributed at intervals along the arc-shaped contour. A detachable first pin 33 can connect different pin holes 38 on the kneeling pad 32 to the first pin connecting hole 35 to adjust the angle of the kneeling pad 32.

[0050] In a specific embodiment of this utility model, the kneeling pad 32 is provided with three pin holes 38, and the kneeling pad is in the following state: Figure 6 As shown, where Figure 6 (a) is a schematic diagram of the kneeling pad when it is at the left angle; Figure 6 (b) is a schematic diagram of the kneeling pad at the middle angle; Figure 6(c) is a schematic diagram showing the kneeling pad at the right angle. This invention allows users to adopt different crunch positions simply by adjusting the angle of the kneeling pad 32, thus improving the user experience.

[0051] Furthermore, in the second embodiment of the kneeling pad assembly 3 of this utility model, in addition to the above-mentioned structure, the kneeling pad assembly 3 also has the following features: a third connecting seat 34 is disposed in the middle of the sliding seat 31; a first pin connecting hole 35 is disposed on the side of the kneeling pad 32 away from the armrest 4; to make the connection of the kneeling pad 32 more stable, a second pin connecting hole 36 is also provided on the side of the third connecting seat 34 away from the first pin connecting hole 35 on the sliding seat 31; and an arc-shaped strip groove 39 matching the second pin connecting hole 36 is provided on the kneeling pad 32, through which a detachable second pin can be connected to the second pin connecting hole via the strip groove 39 to limit and fix the kneeling pad 32. This utility model can use the first pin 33 and the second pin (with the same structure as the first pin) to jointly limit the kneeling pad, making the connection of the kneeling pad more stable.

[0052] Furthermore, in the third embodiment of the kneeling pad assembly 3 of this utility model, a third connecting seat 34 is provided on the sliding seat 31, and a kneeling pad shaft 37 is provided at the position corresponding to the third connecting seat 34 on the kneeling pad 32. The kneeling pad shaft 37 is rotatably connected to the third connecting seat 34, so that the kneeling pad 32 can rotate on the sliding seat 31. A second pin connecting hole 36 is also provided on the sliding seat 31 next to the third connecting seat 34. An arc-shaped strip groove 39 matching the second pin connecting hole 36 is provided on the kneeling pad 32. The second pin can be connected to the second pin connecting hole through the strip groove 39, so that the kneeling pad 32 can rotate within the space defined by the strip groove 39. In this embodiment, the kneeling pad 32 can rotate within the space defined by the strip groove 39. When using the abdominal exerciser, the user can rotate the kneeling pad 32 while curling up, increasing the fun of the exercise.

[0053] In this embodiment of the invention, the three embodiments of the kneeling pad assembly 3 can be combined with the adjustable support 12 to achieve more complex and diverse fitness purposes. For example, when the user adjusts the slide rail 2 and further adjusts the angle of the kneeling pad 32, the sliding direction of the human body and the orientation of the shoulders have more varied angular relationships. In addition, in the third embodiment of the adjustable support 12, by setting the adjustable support 12 at the end away from the armrest 4, by adjusting the angle of the seat pad 32, the sliding orientation and sliding direction of the human body can be different, so as to achieve the purpose of exercising different abdominal muscle groups.

[0054] Furthermore, in this embodiment of the invention, the device is connected to the sliding seat 31 via a pin as shown in the accompanying drawings. This invention supports kneeling pads 32 with different structures, such as... Figure 4 The kneeling pad 32 shown is an integral structure, and can also be as follows: Figure 7The kneeling pad 5 shown has four foam sticks. The structural features of the sliding seat 31 of this utility model allow users to replace the kneeling pad as needed, further increasing the flexibility of movement and improving the user experience.

[0055] This utility model embodiment provides an abdominal exercise device including a slide rail support 11 and a handrail 4 disposed at the end of the slide rail support 11.
