Abstract

An adjustable weight-loaded dip-chin machine. Dip bars and chin bars with means for vertical adjustment are mounted on columns, which in turn are mounted on a base. An arm is pivotally attached to the base, and weights can be added to an arm spindle attached to the arm. A belt is attached to the arm, and weights added to the arm spindle resist upward motion of an exerciser performing dips or chins. Elastic bands may be added connecting the arm to the base, and/or the belt to the base, which serve to render the exercise more strenuous. Dip bars incorporate a plurality of dip bar legs, each a differing distance from the other dip bar. Chin bars incorporate a downwardly-sloping dogleg. An alternate embodiment adjustable dip-chin machine incorporates a weight stack which can be attached to the belt. Stack weights selected from the weight stack render exercise more strenuous.

Claims

1. An adjustable dip-chin machine comprising an arm pivotally attached to a base;

an arm spindle attached to said arm, said arm spindle being sized to accept weights;

a pair of columns;

a dip bar removably and directly attached to each said column; and

means of adjusting a height of each said dip bar on its respective column;

the means of adjusting dip bar height comprising a bracket attached to said dip bar, and a plurality of column apertures in each said column, said bracket comprising a bracket first leg attached along one edge of a bracket spine, and a bracket second leg attached along an opposite edge of said bracket spine, said bracket first leg, bracket second leg, and bracket spine defining a bracket aperture, said bracket aperture being sized to admit one said column, and a bracket pin attached to said bracket second leg, each said column aperture being sized to admit said bracket pin, whereby said bracket pin may be inserted into one said column aperture, and then said bracket rotated about said bracket pin until said column is disposed within said bracket aperture.

2. The adjustable dip-chin machine of claim 1 wherein said column comprises a pair of opposed column faces and a pair of opposed column sides, said plurality of column apertures being disposed in one said column side, and said bracket further comprises a bracket second leg extension and said bracket pin is mounted to said bracket second leg extension, a bracket pin offset from said bracket spine equaling or exceeding a column aperture offset from an adjacent said column face.

3. An adjustable dip-chin machine comprising an arm pivotally attached to a base;

an arm spindle attached to said arm, said arm spindle being sized to accept weights;

a pair of columns;

a dip bar removably and directly attached to each said column;

means of adjusting a height of each said dip bar on its respective column;

a chin bar removably and directly attached to each said column; and

means of adjusting a height of each said chin bar on its respective column;

the means of adjusting chin bar height comprising a bracket attached to said chin bar, and a plurality of column apertures in each said column, said bracket comprising a bracket first leg attached along one edge of a bracket spine, and a bracket second leg attached along an opposite edge of said bracket spine, said bracket first leg, bracket second leg, and bracket spine defining a bracket aperture, said bracket aperture being sized to admit one said column, and a bracket pin attached to said bracket second leg, each said column aperture being sized to admit said bracket pin, whereby said bracket pin may be inserted into one said column aperture, and then said bracket rotated about said bracket pin until said column is disposed within said bracket aperture.

4. The adjustable dip-chin machine of claim 3 wherein said column comprises a pair of opposed column faces and a pair of opposed column sides, said plurality of column apertures being disposed in one said column side, and said bracket further comprises a bracket second leg extension and said bracket pin is mounted to said bracket second leg extension, a bracket pin offset from said bracket spine equaling or exceeding a column aperture offset from an adjacent said column face.

5. An adjustable dip-chin machine comprising a pair of columns attached to a base;

a dip bar removably and directly attached to each said column;

means of adjusting a height of each said dip bar on its respective column;

a weight stack attached to a belt, whereby upwards motion of said belt is resisted by stack weights selected from said weight stack;

the means of adjusting dip bar height comprising a bracket attached to said dip bar, and a plurality of column apertures in each said column, said bracket comprising a bracket first leg attached along one edge of a bracket spine, and a bracket second leg attached along an opposite edge of said bracket spine, said bracket first leg, bracket second leg, and bracket spine defining a bracket aperture, said bracket aperture being sized to admit one said column, and a bracket pin attached to said bracket second leg, each said column aperture being sized to admit said bracket pin, whereby said bracket pin may be inserted into one said column aperture, and then said bracket rotated about said bracket pin until said column is disposed within said bracket aperture.

6. The adjustable dip-chin machine of claim 5 wherein said each column comprises a pair of opposed column faces and a pair of opposed column sides, said plurality of column apertures being disposed in one said column side, and said bracket further comprises a bracket second leg extension and said bracket pin is mounted to said bracket second leg extension, a bracket pin offset from said bracket spine equaling or exceeding a column aperture offset from an adjacent said column face.

7. The adjustable dip-chin machine of claim 6 wherein each said dip bar comprises a plurality of dip bar legs, said dip bar legs being separated by mutually differing distances from the other said dip bar.

8. The adjustable dip-chin machine of claim 6 further comprising a chin bar removably attached to each said column, and means of adjusting a height of each said chin bar on its respective column.

9. The adjustable dip-chin machine of claim 8 wherein the means of adjusting chin bar height comprises a bracket attached to said chin bar, and a plurality of column apertures in each said column, said bracket comprising a bracket first leg attached along one edge of a bracket spine, and a bracket second leg attached along an opposite edge of said bracket spine, said bracket first leg, bracket second leg, and bracket spine defining a bracket aperture, said bracket aperture being sized to admit one said column, and a bracket pin attached to said bracket second leg, each said column aperture being sized to admit said bracket pin, whereby said bracket pin may be inserted into one said column aperture, and then said bracket rotated about said bracket pin until said column is disposed within said bracket aperture.

10. The adjustable dip-chin machine of claim 9 wherein each said column comprises a pair of opposed column faces and a pair of opposed column sides, said plurality of column apertures being disposed in one said column side, and said bracket further comprises a bracket second leg extension and said bracket pin is mounted to said bracket second leg extension, a bracket pin offset from said bracket spine equaling or exceeding a column aperture offset from an adjacent said column face.

11. An adjustable dip-chin machine comprising a pair of columns attached to a base;

a chin bar removably and directly attached to each said column;

means of adjusting a height of each said chin bar on its respective column; and

a weight stack attached to a belt, whereby upwards motion of said belt is resisted by stack weights selected from said weight stack;
