Abstract

A training apparatus for performing a training of a rectus abdominis muscle. The training apparatus including an operation arm supported to be swingable by receiving a contact pressure from an arm of a user. A rotary section is provided carrying a load of a weight stack and supported to be rotatable by a swing of the operation arm. A seat section is provided to be swingably supported. A push section is provided to be swingably supported, and arranged to swing the seat section while supporting the seat section at a lower end portion of the seat section. In the training apparatus, the push section swings in one of a first state uncooperative with a rotation of the rotary section and a second state cooperative with the rotation of the rotary section.

Claims

1. A training apparatus for performing a training of a rectus abdominis muscle, comprising:

an operation arm supported to be swingable by receiving a contact pressure from an arm of a user;

a rotary section carrying a load of a weight stack and supported to be rotatable by a swing of the operation arm;

a seat section swingably supported; and

a push section swingably supported, and arranged to swing the seat section while supporting the seat section at a lower end portion of the seat section,

wherein the push section swings in one of a first state uncooperative with a rotation of the rotary section and a second state cooperative with the rotation of the rotary section.

2. A training apparatus as claimed in claim 1, further comprising a switching device for switching the push section between the first and second states, the switching device comprising:

a sleeve pivotally attached to the rotary section and formed with a side bore;

a main shaft pivotally attached to the push section and inserted in the sleeve; and

an obstruction member arranged to be insertable into the sleeve through the side bore of the sleeve thereby switching between ensuring and obstructing an insertion path defined in the sleeve for the main shaft,

wherein the push section is brought into the first state uncooperative with the rotation of the rotary section so to be swingable, when the obstruction member ensures the insertion path for the main shaft, and

wherein the push section is brought into the second state cooperative with the rotation of the rotary section so as to be swingable, when the obstruction member is inserted into the sleeve through the side bore to obstruct the insertion path.

3. A training apparatus as claimed in claim 2, wherein the switching device further comprises:

a device for taking the obstruction member to one of a first position ensuring the insertion path for the main shaft and a second position obstructing the insertion path; and

a device for fastening the obstruction member taken to one of the first and second positions.

4. A training apparatus as claimed in claim 1, wherein the operation arm is adjustable for a starting position at which the swing of the operation arm starts.
