Abstract
Abstract A weight machine for use by persons confined to a wheelchair designed so that the person so confined may independently, or with minimal assistance, use the exercise machine. The frame of the exercise machine extends outwardly beyond the backrest and a plurality of ramp members are pivotally connected to said frame so that the person confined to a wheelchair can back onto the ramp members and each will pivot toward the machine thereby allowing the person confined to the wheelchair to back up to the machine until their back is against the backrest of the exercise machine. The backrest is positioned to provide support for the person's spine throughout the various exercises which may be performed. When the exercises are completed, the wheelchair can be rolled forward causing the ramp members to pivot away from the weight machine and allowing the person confined to the wheelchair to exit.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
207 words
An exercise machine for persons confined to a wheelchair, comprising: a frame having a back rest and a plurality of base members extending outwardly beyond said back rest, said base members each having an upwardly extending arm having a pivot bar attached thereto; a plurality of ramp members for accepting the wheels of a wheelchair, said ramp members pivotly secured to said pivot bar; a multiplicity of resistance members secured to said frame; whereby the ramp members can be pivoted away from the back rest so that a person confined to a wheelchair can back the wheels of the wheelchair onto the ramp members until the weight of the wheelchair and the person confined to the wheelchair causes the ramp members to pivot toward the back rest allowing the wheelchair to roll in the direction of the weight machine until the back of the person confined to the wheelchair comes in contact with the back rest so that the person confined to the wheelchair can use the multiplicity of resistance members for exercising and after exercising, the wheelchair can be rolled away from the back rest causing the ramp members to pivot away from the exercise machine so that the person confined to the wheelchair may exit.
Claim 2
Dependent Claim
207 words
An exercise machine for persons confined to a wheelchair, comprising: a frame having a back rest and a plurality of base members extending outwardly beyond said back rest, said base members each having an upwardly extending arm having a pivot bar attached thereto; a plurality of ramp members for accepting the wheels of a wheelchair, said ramp members pivotly secured to said pivot bar; a multiplicity of resistance members secured to said frame; whereby the ramp members can be pivoted away from the back rest so that a person confined to a wheelchair can back the wheels of the wheelchair onto the ramp members until the weight of the wheelchair and the person confined to the wheelchair causes the ramp members to pivot toward the back rest allowing the wheelchair to roll in the direction of the weight machine until the back of the person confined to the wheelchair comes in contact with the back rest so that the person confined to the wheelchair can use the multiplicity of resistance members for exercising and after exercising, the wheelchair can be rolled away from the back rest causing the ramp members to pivot away from the exercise machine so that the person confined to the wheelchair may exit.
Claim 3
Dependent Claim
14 words
The exercise machine recited in claim 1 wherein said ramp members are channel shaped.
Claim 4
Dependent Claim
15 words
The exercise machine recited in claim 2 wherein an interconnecting bar connects said ramp members.
Claim 5
Dependent Claim
65 words
The exercise machine recited in claim 3 wherein each base member has a shock absorber whereby when said ramp members are pivoted toward the back rest, said ramp members will rest on the shock absorber thereby cushioning the impact of the ramp members when said ramp members are pivoted as the result of the weight of the wheelchair and the person confined to the wheelchair.
