Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
162 words
An exerciser of the treadmill type, including in combination: a rigid frame having a pair of rigid side members, a forward portion and a rear portion, and means mounted on said frame providing a gripping surface for a hand of a person using the exerciser, a series of rollers rotatably supported by and lying between said side members and supported at each said side member at a series of points forming a line having a relatively flat rear portion merging upwardly into a generally concave forward portion located at a higher elevation than said rear portion, a continuous belt having an upper course lying above all said rollers and a lower course below all said rollers, said belt having its upper course supported directly by said rollers, whereby a person walking, jogging, or running on said belt automatically locates himself fore-and-aft of said upper course by the balance between his weight, his speed, and the variation in inclination along said curved path.
Claim 2
Dependent Claim
162 words
An exerciser of the treadmill type, including in combination: a rigid frame having a pair of rigid side members, a forward portion and a rear portion, and means mounted on said frame providing a gripping surface for a hand of a person using the exerciser, a series of rollers rotatably supported by and lying between said side members and supported at each said side member at a series of points forming a line having a relatively flat rear portion merging upwardly into a generally concave forward portion located at a higher elevation than said rear portion, a continuous belt having an upper course lying above all said rollers and a lower course below all said rollers, said belt having its upper course supported directly by said rollers, whereby a person walking, jogging, or running on said belt automatically locates himself fore-and-aft of said upper course by the balance between his weight, his speed, and the variation in inclination along said curved path.
Claim 3
Dependent Claim
41 words
The exerciser of claim 1 having, below said belt, diagonally extending means adjustable in length joining said side members for enabling adjustment of the degree of rack of the rollers and belt, so as to control the path Of the belt.
Claim 4
Dependent Claim
24 words
The exerciser of claim 2 wherein there are two said diagonal means crossing each other, whereby the friction on the rollers can be adjusted.
Claim 5
Dependent Claim
61 words
The exerciser of claim 1 having, below said belt, a pair of diagonally extending and crossing turnbuckles joining said side members and enabling adjustment of the degree of rack of the rollers and belt, so as to control the path of the belt, and for varying the friction on the rollers so as to restrict or free their freedom of rotation.
Claim 6
Dependent Claim
96 words
The exerciser of claim 1 in which said means providing a gripping surface is a handle comprising two parallel members joined by a cross member at an outer end and attached to said side members at inner ends forward of said forward portion of said series of rollers, said parallel members being pivotally supported by said side members for movement between a lower generally horizontal inactive position wherein said cross member lies to the rear of said belt and an upper generally vertical position, and releasable means for maintaining said handle in said generally vertical position.
Claim 7
Dependent Claim
125 words
The exerciser of claim 1 wherein the lower edges of said side members have a main flat portion for resting on a floor and supporting said exerciser and frictionally resisting sliding of the exerciser along the floor, and a forward upwardly inclined portion, and an additional roller rotatably supported by and between said side members at their said forward portions, said roller extending below the edge of said forward portion but not below the edge of said main portion, whereby said roller does not reduce the normal ability of the exerciser to resist sliding movement but, when the rear end of the exerciser is raised, said roller engages the floor and supports the entire exerciser, enabling it to be moved along readily on said roller.
Claim 8
Dependent Claim
41 words
The exercizer of claim 1 including in combination: a foremost roller forward of and lower than the forward portion of said series of rollers, rotatably supported by and lying between said side members, said belt being trained over said foremost roller.
Claim 9
Dependent Claim
61 words
The exerciser of claim 7 wherein said foremost roller has a pair of identical flywheels, one on each side the same distance from the center of said foremost roller, mounted inboard of said side members, for providing a smooth flywheel action tending to keep the velocity of the belt steadier and balancing the action while guiding the belt along its path.
Claim 10
Dependent Claim
41 words
The exerciser of claim 8 having, below said belt, diagonally extending means adjustable in length joining said side members and enabling adjustment of the degree of rack of the rollers and belt, so as to control the path of the belt.
Claim 11
Dependent Claim
62 words
The exerciser of claim 7 having, below said belt, a pair of diagonally extending turnbuckles crossing each other joining said side members and enabling adjustment of the degree of rack of the rollers and belt, so as to control the path of the belt, and for varying the friction on the rollers so as to restrict or free their freedom of rotation.
