Abstract

The present invention provides a multifunctional exercise apparatus for allowing a user to perform rowing exercise or other exercises. The exercise apparatus includes a frame, a sliding seat, a cord winder, a spiral spring connected to the cord winder, a cord connected to the cord winder, a flywheel for generating an exercise resistance, and one-way transmission mechanism connected between the cord winder and the flywheel. The user is able to seat on the sliding seat and slide backward and forward in accord with repeating movement of pulling the cord to perform the rowing exercise, or having lower limbs partially press upon the sliding seat and two hands grasp gripping portions at a front end of the frame to perform other exercises such as stretching exercises. When performing other exercises, a distal end of the cord is connected to the sliding seat and backward movement of the sliding seat would drive the flywheel.

First claim

What is claimed is:

1. An exercise apparatus for allowing a user to perform rowing exercise, comprising:
a frame;
a sliding seat having at least one connecting portion, the sliding seat adapted to be moved along a movement path, the movement path defining a front end and a rear end;
a pedal set mounted on the frame for supporting the user's feet during the rowing exercise;
a cord receiving device having at least one cord winder, at least one elastic member and at least one cord, the at least one cord winder including a first cord winder, each of the at least one cord winder being rotatable in both directions with respect to the frame, the at least one elastic member including a first elastic member, each of the at least one elastic member mounted between the frame and the respective cord winder and being deformed by rotational movement of the respective cord winder in a first rotational direction to accumulate an elastic restoring force, the elastic restoring force causing the respective cord winder to rotate in a second rotational direction, the at least one cord including a first cord, each of the at least one cord having a first end and a second end, the first end connected to the respective cord winder, each cord being wrapped onto the respective cord winder as the respective cord winder is rotated in the second rotational direction, wherein the first elastic member is mounted between the frame and the first cord winder, the first end of the first cord is connected to the first cord winder;
a resistance device having a rotating member pivotally mounted to the frame for generating an exercise resistance;
a one-way transmission mechanism mounted between the cord receiving device and the rotating member of the resistance device, when the first cord winder is rotated in the first rotational direction, the one-way transmission mechanism is operable to engage with the rotating member for driving the rotating member to rotate in a predetermined rotational direction; when the first cord winder is rotated in the second rotational direction, the one-way transmission mechanism is operable to disengage from the rotating member; and
a handle connected to the second end of the first cord for allowing the user to grasp during the rowing exercise;
wherein the second end of one of the at least one cord of the cord receiving device is operable to connect with the connecting portion of the sliding seat for allowing the user to perform stretching or crunch exercises; the frame has at least one gripping portion; the when the user performs stretching or crunch exercises, the user has lower limbs partially press upon the sliding seat and move with the sliding seat; when the sliding seat is slid to one end of the movement path, the sliding seat pulls the respective cord to drive the respective cord winder to rotate in the first rotational direction, and the one-way transmission mechanism is effective to transmit power to the rotating member so as to drive the rotating member to rotate in the predetermined rotational direction; the gripping portion is provided for allowing the user to grasp during stretching or crunch exercises.

2. The exercise apparatus as claimed in claim 1 , wherein when the user performs stretching or crunch exercises, the second end of the first cord is detachably connected to the connecting portion of the sliding seat, and the first cord is extended forward from the sliding seat to the first cord winder, such that when the sliding seat is slid backward, the first cord is pulled to drive the first cord winder to rotate in the first rotational direction.

3. The exercise apparatus as claimed in claim 1 , wherein the at least one cord winder of the cord receiving device includes a second cord winder, the at least one elastic member including a second elastic member, the at least one cord including a second cord, the second cord winder and the first cord winder being rotatable independently, the second elastic member mounted between the frame and the second cord winder, the first end of the second cord connected to the second cord winder; when the second cord winder is rotated in the first rotational direction, the one-way transmission mechanism is operable to engage with the rotating member for driving the rotating member to rotate in the predetermined rotational direction; when the second cord winder is rotated in the second rotational direction, the one-way transmission mechanism is operable to disengage from the rotating member; when the user performs stretching or crunch exercises, the user is able to choose to detachably connect the second end of the first cord or the second end of the second cord to the connecting portion of the sliding seat; when choosing the first cord connected to sliding seat, the first cord is extended forward from the sliding seat and then extended to the first cord winder, so that when the sliding seat is slid backward, the first cord is pulled to drive the first cord winder to rotate in the first rotational direction; when choosing the second cord connected to sliding seat, the second cord is extended backward from the sliding seat and then extended to the second cord winder, so that when the sliding seat is slid forward, the second cord is pulled to drive the second cord winder to rotate in the first rotational direction.

4. The exercise apparatus as claimed in claim 2 , wherein the handle is detachably connected to the second end of the first cord; when the second end of the first cord is connected to the connecting portion of the sliding seat, the handle is temporarily detached from the second end of the first cord.

5. The exercise apparatus as claimed in claim 3 , wherein the handle is detachably connected to the second end of the first cord; when the second end of the first cord is connected to the connecting portion of the sliding seat, the handle is temporarily detached from the second and of the first cord.

6. The exercise apparatus as claimed in claim 1 , wherein the at least one cord winder of the cord receiving device includes a second cord winder, the at least one elastic member including a second elastic member, the at least one cord including a second cord, the second cord winder and the first cord winder being rotatable independently, the second elastic member mounted between the frame and the second cord winder, the first end of the second cord connected to the second cord winder; when the second cord winder is rotated in the first rotational direction, the one-way transmission mechanism is operable to engage with the rotating member for driving the rotating member to rotate in the predetermined rotational direction; when the second cord winder is rotated in the second rotational direction, the one-way transmission mechanism is operable to disengage from the rotating member; when the user performs stretching or crunch exercises, the second end of the second cord is connected to the connecting portion of the sliding seat, so that when the sliding seat is slid to one end of the movement path, the second cord is pulled to drive the second cord winder to rotate in the first rotational direction.

7. The exercise apparatus as claimed in claim 6 , wherein when the user performs stretching or crunch exercises, the second cord is extended forward from the sliding seat and then extended to the second cord winder, so that when the sliding seat is slid backward, the second cord is pulled to drive the second cord winder to rotate in the first rotational direction.

8. The exercise apparatus as claimed in claim 7 , the second end of the second cord is detachably connected to the connecting portion of the sliding seat.

9. The exercise apparatus as claimed in claim 6 , wherein when the user performs stretching or crunch exerc
