[0004] The utility model aims to provide a tiltable abdominal wheel, which can realize tilting and turning movement to effectively exercise the side abdominal muscles of the user.

[0005] The purpose of the utility model is achieved through the following technologies:

[0006] A tiltable abdominal wheel comprises an elbow support component and a running mechanism arranged at the bottom of the elbow support component, characterized in that the running mechanism comprises an adapter, a wheel frame and a steering wheel, the steering wheel is rotatably arranged on the wheel frame, the adapter can be rotatably arranged on the wheel frame around a first axis extending up and down, the elbow support component can be rotatably connected to the adapter around a second axis extending front and back, a driving component is arranged at the bottom of the elbow support component, when the elbow support component rotates and tilts around the second axis, the driving component can drive the wheel frame to rotate around the first axis, so that when exercising, the user can tilt and press down the abdominal wheel to drive the wheel frame to rotate, and the steering wheel will rotate accordingly, and pushing the abdominal wheel forward will become an arc steering movement, which can well exercise the user's side abdominal muscles.

[0007] The driving part includes two first driving surfaces arranged left and right and inclined up and down or extending in an arc shape up and down. The wheel frame is provided with two second driving surfaces that can be matched with the two first driving surfaces. The arrangement is such that when the elbow support component rotates and tilts around the second axis, the first driving surface moves downward and cooperates with the second driving surface to drive the wheel frame to rotate around the first axis, so that the abdominal wheel turns toward the inclined side of the elbow support component. In this way, the wheel frame will be driven to rotate by the first driving part that is tilted downward, and the abdominal wheel can turn.

[0008] A first elastic reset member is arranged between the adapter and the elbow support member, and the first elastic reset member drives the elbow support member to reset to a horizontal state.

[0009] The first elastic reset member includes two coil springs, which are respectively arranged on the left and right sides of the adapter. One end of the coil spring is pressed against the adapter and the other end is pressed against the elbow support member. In this way, when the abdominal wheel tilts to one side, the coil spring on one side can drive the abdominal wheel to reset to a horizontal state.

[0010] A second elastic reset member is arranged between the adapter and the wheel frame, and the second elastic reset member drives the wheel frame to reset to an initial position.

[0011] The second elastic reset member includes a left torsion spring and a right torsion spring distributed on the left and right sides. The left torsion spring and the right torsion spring both include a spiral body installed at the bottom of the elbow support component and two force-bearing sections extending outward from the spiral body. One force-bearing section of the left torsion spring and the right torsion spring are connected to each other, and the other force-bearing section rests on the wheel frame. When the wheel frame rotates to one side, the left torsion spring and the right torsion spring are driven to be deformed under force. The left torsion spring and the right torsion spring can drive the wheel frame to reset to its initial position.

[0012] Two mounting posts and two anti-dropping washers are arranged at the bottom of the elbow support component.

[0025] Reference Figures 1 to 8 A tiltable abdominal wheel comprises an elbow support component 1, a steering wheel 52, a wheel frame 51, an adapter 13, a balancing wheel 2 and two armrests 3. The elbow support component 1 is formed with two connecting parts 12 extending downward. The wheel axle of the balancing wheel 2 is rotatably connected to the connecting part 12 so that the balancing wheel 2 is rotatably connected and arranged at the bottom of the elbow support component 1. The wheel axle of the balancing wheel 2 extends horizontally in the left and right directions, and the balancing wheel 2 has an arc-shaped outer peripheral surface, which is convenient for the steering of the abdominal wheel. The two armrests 3 are arranged at a distance at the front end of the elbow support component 1 and extend forward and upward for the convenience of the user to grasp.

[0026] The steering wheel 52 is rotatably arranged on the wheel frame 51, the adapter 13 can be rotatably arranged on the wheel frame 51 around a first axis extending up and down, the elbow support component 1 can be rotatably connected to the adapter 13 around a second axis extending front and back, a first driving part 15 is arranged at the bottom of the elbow support component 1, and the first driving part 15 and the elbow support component 1 are integrally formed. When the elbow support component 1 rotates and tilts around the second axis, the first driving part 15 can drive the wheel frame 51 to rotate around the first axis. In this way, when exercising, the user can drive the wheel frame 51 to rotate by tilting the abdominal wheel downward, and the steering wheel 52 will rotate accordingly. Pushing the abdominal wheel forward will become a steering movement in an arc, which can exercise well. To the user's side abdominal muscles, the first driving part 15 includes two first driving surfaces 151 distributed left and right and extending up and down obliquely, a second driving part 511 is formed on the wheel frame 51, and two second driving surfaces 512 that can be matched with the two first driving surfaces 151 are formed on the second driving part 511. It is configured that when the elbow support component 1 rotates and tilts around the second axis, the first driving part 15 moves downward, and the first driving surface 151 cooperates with the second driving surface 512 to drive the wheel frame 51 to rotate around the first axis, so that the abdominal wheel turns toward the inclined side of the elbow support component 1, so that the wheel frame 51 will be driven to rotate by the first driving part 15 that is tilted downward, and the abdominal wheel can turn.

[0027] The side of the adapter 13 is formed with a first bolt through hole 132, and the bottom of the elbow support member 1 is formed with a mounting portion 11, and the mounting portion 11 is formed with a second bolt through hole 111 and a mounting hole 112 that match the first bolt through hole 132. The upper section of the adapter 13 extends into the mounting hole 112 and is locked by the first bolt 133 and the first nut to realize the rotatable connection between the adapter 13 and the mounting portion 11. The first bolt 133 crosses the mounting portion 11 and the adapter 13 to connect the adapter 13 to the mounting portion 11. The first bolt 133 The axis is the second axis. A transfer groove 54 opening upward to accommodate the transfer member 13 is formed on the wheel frame 51, and two bearings 7 are arranged at the bottom of the transfer groove 54, so that the wheel frame 51 can rotate more smoothly. A third bolt through hole 55 is formed at the bottom of the transfer groove 54, and a screw hole 134 is formed at the bottom of the transfer member 13. The second bolt 53 is used to pass through the third bolt through hole 55 from the bottom of the wheel frame 51 and threadedly cooperate with the screw hole 134 to lock the transfer member 13 and the wheel frame 51. The axis of the second bolt 53 is the first axis. During installation, insert the upper section of the adapter 13 into the mounting hole 112, use the first bolt 133 to pass through the second bolt hole 111 and the first bolt hole 132 in sequence, and then tighten it with a nut, and use the second bolt 53 to pass through the third bolt hole 55 and the screw hole 134 to lock the lower section of the adapter 13 with the wheel frame 51. Alternatively, you can first insert the adapter 13 into the adapter groove 54, use the second bolt 53 to pass through the third bolt hole 55 and the screw hole 134 to lock the lower section of the adapter 13 with the wheel frame 51, and then insert the upper section of the adapter 13 into the mounting hole 112, use the first bolt 133 to pass through the second bolt hole 111 and the first bolt hole 132 in sequence and tighten them with a nut.

[0028] The elbow support component 1 is in a horizontal state in a natural state. The user's elbow presses down the side of the elbow support component 1 to make it tilted. A first elastic reset component 14 is arranged between the adapter 13 and the elbow support component 1. The first elastic reset component 14 drives the tilted elbow support component 1 to be reset to a horizontal state. The first elastic reset component 14 includes two coil springs, which are arranged on the left and right sides of the adapter 13. Connecting grooves 131 are formed on the left and right sides of the adapter 13. One end of the coil spring is embedded in the connecting groove 131, and the other end is pressed against the elbow support component 1. In this way, when the abdominal wheel tilts to one side, the coil spring on one side can drive the abdominal wheel to be reset to a horizontal state.

[0029] The wheel frame 51 is in an initial position in a natural state, and the two steering wheels 52 on the wheel frame 51 in the initial position face forward. At this time, the abdominal wheel is used to make a forward and backward movement with a linear motion trajectory. When one side of the abdominal wheel is tilted, the wheel frame 51 can be rotated to the rotation position. At this time, the abdominal wheel is used to make a forward and backward movement with an arc motion trajectory. A second elastic reset member 16 is arranged between the adapter 13 and the wheel frame 51. The second elastic reset member 16 drives the wheel frame 51 to reset to the initial position. The second elastic reset member 16 is a left torsion spring 161 and a right torsion spring 162 distributed on the left and right sides of the bottom of the elbow support component 1. The left torsion spring 161 and the right torsion spring 162 both include a spiral body and two force-bearing sections extending outward from the spiral body. One force-bearing section of the left torsion spring 161 and the right torsion spring 162 is connected to each other, and the other force-bearing section abuts against the rear of the wheel frame 51. At the end, when the wheel frame 51 rotates toward one side, the left torsion spring 161 or the right torsion spring 162 is driven to deform under force. For example, when the wheel frame 51 rotates toward the left side, the left torsion spring 161 can be driven to deform under force. When the force driving the wheel frame 51 to rotate disappears, the left torsion spring 161 or the right torsion spring 162 can drive the wheel frame to return to its initial position. Two mounting columns 17 and two anti-detachment gaskets 171 distributed on the left and right are provided at the bottom of the elbow support component 1. The two anti-detachment gaskets 17 and the two mounting columns 17 are fixed to the two mounting columns 17 by bolts. The spiral bodies of the left torsion spring 161 and the right torsion spring 162 are respectively mounted on the two mounting columns 17 and are restricted from detaching from the mounting columns 17 by the anti-detachment gaskets 171. A supporting column 18 is also formed between the two mounting columns 17. The connection between the left torsion spring 161 and the right torsion spring 162 abuts against the abutment column 18, which can enhance a certain degree of stability.
