## Abstract

An adjustably tensioned roller massage system provides a pair of roller massage assemblies in opposed adjustable tensioned or spaced relation to allow engagement of each one of a pair of roller massage assemblies on a corresponding massageable portion of a body.

## Claims

### Claim 1

An apparatus, comprising:
a cross member having a first end opposite a second end;
a drive member affixed to a first end portion of a drive shaft rotationally supported in said cross member;
a first driven member affixed to a first end portion of a first threaded shaft rotationally supported in said cross member orthogonal to said drive shaft, said drive member rotationally engaged to first driven member to rotate said first threaded shaft;
a first follower threadingly engaged on said first threaded shaft, said first follower movable along said first threaded shaft by rotation of said first threaded shaft between a first threaded shaft first end and a first threaded shaft second end;
a first handle coupled to said cross member first end; and
a first elastic member or a first inelastic member coupled between said first follower and said first handle; said first elastic member or said first inelastic member responsive to movement of said first follower along said first threaded shaft.

### Claim 2 (depends on 1)

The apparatus of claim 1, further comprising wherein movement of said first follower along said first threaded shaft between a first threaded shaft first end and a first threaded shaft second end increases or decreases elastic force in said first elastic member.

### Claim 3 (depends on 1)

The apparatus of claim 1, further comprising wherein movement of said first follower along said first threaded shaft between a first threaded shaft first end and a first threaded shaft second end generates tension force in said first inelastic member sufficient to move said first handle.

### Claim 4 (depends on 2, 3)

The apparatus of any one of claim 2 or 3, further comprising a first roller assembly rotatably coupled to said first handle.

### Claim 5 (depends on 1)

The apparatus of claim 1, further comprising:
a second driven member affixed to a first end portion of a second threaded shaft rotationally supported in said cross member orthogonal to said drive shaft, said drive member rotationally engaged to said second driven member to rotate said second threaded shaft;
a second follower threadingly engaged on said second threaded shaft, said second follower movable along said second threaded shaft by rotation of said second threaded shaft between a second threaded shaft first end and a second threaded shaft second end;
a second handle coupled to said cross member second end; and
a second elastic member or a second inelastic member coupled between said second follower and said second handle, said second elastic member or said second inelastic member responsive to movement of said second follower along said second threaded shaft.

### Claim 6 (depends on 5)

The apparatus of claim 5, further comprising wherein movement of said second follower along said second threaded shaft between a second threaded shaft first end and a second threaded shaft second end increases or decreases elastic force in said second elastic member.

### Claim 7 (depends on 5)

The apparatus of claim 5, further comprising wherein movement of said second follower along said second threaded shaft between a second threaded shaft first end and a second threaded shaft second end generates tension force in said second inelastic member sufficient to move said second handle.

### Claim 8 (depends on 6, 7)

The apparatus of any one of claim 6 or 7, further comprising a first roller assembly rotatably coupled to said first handle and a second roller assembly rotatably coupled to said second handle.

### Claim 9 (depends on 8)

The apparatus of claim 8, further comprising a first pair of handle supports each having a first handle support first end opposite a first handle support second end, said first handle support first ends correspondingly pivotally mounted proximate said cross member first end and said cross member second end, first handle support second ends correspondingly pivotally mounted to said first handle and said second handle.

### Claim 10 (depends on 9)

The apparatus of claim 9, further comprising a second pair of handle supports each having a second handle support first end opposite a second handle support second end, said second handle support first ends correspondingly pivotally mounted to said cross member a distance inward of said first handle support first ends pivotally mounted proximate said cross member first end and said cross member second end, said second handle support second ends correspondingly pivotally mounted to said first handle and said second handle a distance inward of said first handle support second ends correspondingly pivotally mounted to said first handle and said second handle.

### Claim 11 (depends on 9)

The apparatus of claim 9, wherein said first elastic member or said first inelastic member coupled between said first follower and said first one of said pair of first handle supports, and wherein said second elastic member or said second inelastic member coupled between said second follower and said second one of said pair of first handle supports.

### Claim 12 (depends on 5)

The apparatus of claim 5, wherein said drive member comprise a drive gear, and wherein said first and second driven members each comprise a driven gear, said drive gear rotatingly meshes with said first and second driven gears.

### Claim 13 (depends on 5)

The apparatus of claim 5, wherein said first roller assembly comprises one of a plurality of roller assemblies, each of said plurality of roller assemblies configured to interchangeable rotatably couple to said first handle.

### Claim 14 (depends on 13)

The apparatus of claim 13, wherein said second roller assembly comprises one of a plurality of roller assemblies, each of said plurality of roller assemblies configured to interchangeably rotatably couple to said second handle.

### Claim 15 (depends on 14)

The apparatus of claim 14, wherein a first one of said plurality of roller assemblies has an external surface configuration the same as a second one of said plurality of roller assemblies.

### Claim 16 (depends on 14)

The apparatus of claim 14, wherein a first one of said plurality of roller assemblies has an external surface configuration different than a second one of said plurality of roller assemblies.

### Claim 17 (depends on 5)

The apparatus of claim 5, further comprising an adjustment knob external to said cross member, said adjustment knob affixed to a second end portion of said drive shaft.

### Claim 18 (depends on 17)

The apparatus of claim 17, wherein said adjustment knob rotatable to concurrently move a first roller and a second roller.

### Claim 19

The apparatus of 19, wherein said adjustment knob rotatable to concurrently increase or decrease elastic force in said first elastic member and said second elastic member.

### Claim 20 (depends on 1)

The apparatus of claim 1, further comprising an adjustment knob external to said cross member, said adjustment knob affixed to a second end portion of said drive shaft.

### Claim 21 (depends on 20)

The apparatus of claim 20, wherein said adjustment knob rotatable to move a first roller.

### Claim 22 (depends on 20)

The apparatus of claim 20, wherein said adjustment knob rotatable to increase or decrease elastic force in said first elastic member.
