Description

1. Field of the Invention

The present invention relates to an abdominal exercising machine, and more particularly to an abdominal exercising machine that can train the abdomen and the arms of a user simultaneously, can reduce the cost of manufacture and is easy to carry and store.

2. Description of Related Art

Conventional exercising machines have been marketed, such as an exercising bike, a treadmill and an abdominal exercising machine. The conventional exercising machines are used to simulate exercising circumstances and users can exercise and train their muscle by the conventional abdominal exercising machines.
However, the conventional exercising machines are heavy in weight and difficult to carry, and costs of the conventional exercising machines are high. Therefore, a user needs to go to a gymnasium to operate the conventional exercising machines in the gymnasium to train his muscle and cannot exercise at any time as desired and this is inconvenient in use. In addition, each conventional exercising machine only has a single operation function, and only part of the muscle of users can be trained, and this is not versatile in use.

With reference to Figs. 1 and 3, showing the first embodiment of an abdominal exercising machine in accordance with the present invention in use, the user's knees are knelt on the soft sleeves 60 of the hassock 60, 60', the user's elbows are pressed on the soft sheathes 51 of the elbow device 50 and the user's hands hold on to the hand caps 43 of the handle frame 40. Then, the user can hold the hand caps 43 by hands and bend his abdomen to make the pulley fame 30 move relative to the connecting pipes 12 of the main frame 10 and this can train the muscle of the user's arms, abdomen and legs simultaneously.
When the pulley frame 30 is moved upward or downward relative to the main frame 10, the magnet block 314 mounted on one of the linking tabs 312 will move relative to the induction bar 45, and the induction bar 45 can produce a signal to the gauge 44 via the induction wire 452 and the electric cord 441 to record the moving times of the pulley frame 30 relative to the main frame 10 in the electric counter 42. In addition, when the pulley frame 30 is moved relative to the main frame 10 between the bottom pipe 11 and the top pipe 13, the buffer rods 121 mounted on and protruding from the connecting pipes 12 can provide a buffering effect for the pulley frame 30 to prevent the pulley frame 30 from knocking against the main frame 10.
With reference to Figs. 2 and 4 to 6, when the user exercises by the first embodiment of an abdominal exercising machine in accordance with the present invention, the angle between the main frame 10 and the supporting frame 20 can be adjusted by inserting the inserting pin 214 extending through the through hole 213 of the connecting tube 21 and extending into one of the mounting holes 142 of the connecting panel 14. When the angle between the main frame 10 and the supporting frame 20 is changed, the resistance force of the pulley frame 30 relative to the main frame 10 will change according to the angle between the main frame 10 and the supporting frame 20 and this can provide different weight training to the user.
Furthermore, when the user moves the pulley frame 30 relative to the main frame 10 to train his muscle, the elastic beams 316 connected to the ring-pulls 131,315, 111 between the top pipe 13, the base 31 and the bottom pipe 11 also can provide a resistance force to the pulley frame 30. Additionally, when the user wants to store the abdominal exercising machine in accordance with the present invention, the user rotate the supporting main 20 close to the main frame 10 by loosening the inserting pins 214 from the through hole 213 and the corresponding mounting holes 142 and this can reduce the volume of the abdominal exercising machine for easy storage and carriage.
With reference to Figs. 7 and 9, showing another embodiment of the abdominal exercising machine in accordance with the present invention, the operation mode of the other embodiment is mostly the same as the abdominal exercising machine above-mentioned except the following. The user can sit on the cushion 60' of the hassock 60, 60' and the user's hands can respectively hold the grips 731' of the pulling wires 73' to make the pulley fame 30' move relative to the connecting pipes 12' of the main frame 10' and this also can train the muscle of the user's arms, waist and chest simultaneously.

1. The abdominal exercising machine in accordance with the present invention is simple in structure and light in weight to reduce the cost of manufacture and is easy to carry and store.
2. The abdominal exercising machine has a pulley frame 30, 30', a hassock 60, 60', an elbow device 50, 50', a handle frame 40, 40' and two optional auxiliary devices 70', so users can exercise and train the whole bodies at the same time and this is versatile in use.
3. The angle between the main frame 10, 10' and the supporting frame 20, 20' can be adjusted by the inserting pins 214, 214 of the connecting tube 21,21, the resistance force of the pulley frame 30, 30' relative to the main frame 10, 10' will change according to the angle between the main frame 10, 10' and the supporting frame 20, 20' and this can provide different weight trainings to the users.
4. The elastic beams 316, 316' connected to the ring- pulls 131, 131',315, 315', 111, 111 ' between the top pipe 13, 13', the base 31, 31' and the bottom pipe 11, 11' also can provide a resistance force to the pulley frame 30, 30'.
