Abstract

An foldable electric traction machine comprises a front beam, a rear beam and a joint connecting the front beam and the rear beam. A motor is mounted beneath the rear beam. A sliding bracket is mounted on an extension beam and can be moved by the motor. The body of a patient lying on the traction machine will be stretched by the motor driving the sliding bracket along the extension beam. A rope is provide under the front and the rear beam and will be gradually tensioned with the movement of the sliding bracket. Therefore, when the motor is operated, the traction machine not only can improve the user'"'"'s body condition, but also raise the user'"'"'s waist.

Claims

1. A foldable electric traction machine comprising:

a front frame having

a front beam;

a front pad mounted on the front beam; and

a front leg formed on an end of the front beam;

a rear frame having

a rear beam;

a rear pad mounted on the rear beam;

an extension beam slidably engaged with the rear beam;

a rear telescoping support formed on the extension beam; and

a first inner leg adjustably provided in the rear telescoping support and adjusted by a pin;

a joint, which pivotally connects the front frame and the rear frame, forming a middle telescoping leg;

a second inner leg slidably received in the middle telescoping leg;

a motor mounted beneath the rear beam;

a sliding bracket, which is movably mounted on the extension beam and connected to the motor, having a foot holder formed on the sliding bracket; and

a rope having a proximal end and a distal end, said proximal end being connected to said sliding bracket and said distal end being connected to said front leg.

2. The foldable electric traction machine as claimed in claim 1, wherein the front leg is T-shaped has a first end and a second end and said front leg has roller sleeves respectively disposed on both said first end and said second end of said front leg.

3. The foldable electric traction machine as claimed in claim 1, wherein the front frame has a connector mounted beneath the front beam, said connector having a first end and a second end and a first handle being mounted on said first end of the connector and a second handle being mounted on said second end of the connector.

4. The foldable electric traction machine as claimed in claim 1, wherein the rear telescoping leg has a wheel transversally provided on an exterior surface of the rear telescoping leg.

5. The foldable electric traction machine as claimed in claim 1, wherein the rear beam has a strongback formed thereon, said machine further including a locking bolt having a knob, said locking bolt being inserted into the rear beam to fix a position of the extension beam relative to the rear beam.

6. The foldable electric traction machine as claimed in claim 1, wherein the joint further has a bracket where the joint is pivotally connected with the front and rear beams.

7. The foldable electric traction machine as claimed in claim 1, wherein the middle telescoping leg has a pin mounted on the second inner leg to adjust the length of the middle leg.

8. The foldable electric traction machine as claimed in claim 1, wherein the second inner leg defines a slot.

9. The foldable electric traction machine as claimed in claim 8, wherein the second inner leg has two rollers oppositely formed below the slot, the rope being passed through the slot and disposed on the rollers.

10. The foldable electric traction machine as claimed in claim 1, wherein the sliding bracket forms a foot holder thereon, wherein the foot holder defines a channel and a top said foot holder having lower bars integrally formed with the sliding bracket, upper bars provided within the channel and rear bars integrally formed with the upper bars.

11. The foldable electric traction machine as claimed in claim 10, wherein an adjusting handle is provided on the top of the foot holder.

12. The foldable electric traction machine as claimed in claim 10, wherein the front leg forms a front fastener, and the sliding bracket forms a rear fastener, both ends of the rope are fixed to the two fasteners respectively.
