Abstract

Abstract An exercising machine having a frame including a pair of side members and a seat slidably resting upon the side members. A brake shaft attached to the frame. A friction producer slidably engages around the brake shaft. A member for reciprocating the seat on the rails while simultaneously reciprocating the friction producer along the brake shaft when physically operated by the user of the exercising machine.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 391 words
An exercising machine comprising a frame having a pair of side members situated parallelly with respect to each other and whose tops provide a pair of rails; a seat means slidably resting upon said rails of the side members; a brake shaft means attached to said frame; a friction producing means slidably engaging around said brake shaft means; and a means attached to said frame for reciprocating the seat means on the rails of the side members while simultaneously reciprocating the friction producing means along the brake shaft means when physically operated by the user of the exercising machine, said exercising machine additionally comprising a seat moving bar interconnecting the seat means with the means for simultaneously reciprocating the seat means and the friction producing means along the brake shaft means; said exercising machine additionally comprising a pair of bracket members attached to said pair of side members and opposed with respect to each other, said pair of opposed bracket members each including a structure defining a plurality of bracket apertures, said opposed bracket apertures of opposed bracket members being in registry; said means for simultaneously reciprocating the seat means and the friction producing means pivotally lodges within a pair of opposed registered bracket apertures of said pair of bracket members; said means for simultaneously reciprocating includes a structure which partially defines a conduit with at least one conduit aperture; said exercising machine additionally comprising a handlebar including a rod integrally bound thereto and which is telescopically disposed within said conduit, said rod having a plurality of rod apertures which can be telescopically aligned with the conduit aperture in order to adjust the height of said handlebar with respect to the conduit; said exercising machine additionally comprises a cross brace member interconnecting said pair of side members of said frame, said brake shaft means has an end bound to the cross brace member and protrudes aslantly therefrom; said friction producing means comprises a wooden block means including an opening through which said brake shaft means extends in order for the wooden block means to reciprocally traverse the brake shaft means simultaneously to and in the same direction to the seat means being reciprocated; said exercising machine additionally comprising a tension adjusting means engaging the wooden block means for adjusting frictional tension of the wooden block means against the brake shaft means.
Claim 2
Dependent Claim 391 words
An exercising machine comprising a frame having a pair of side members situated parallelly with respect to each other and whose tops provide a pair of rails; a seat means slidably resting upon said rails of the side members; a brake shaft means attached to said frame; a friction producing means slidably engaging around said brake shaft means; and a means attached to said frame for reciprocating the seat means on the rails of the side members while simultaneously reciprocating the friction producing means along the brake shaft means when physically operated by the user of the exercising machine, said exercising machine additionally comprising a seat moving bar interconnecting the seat means with the means for simultaneously reciprocating the seat means and the friction producing means along the brake shaft means; said exercising machine additionally comprising a pair of bracket members attached to said pair of side members and opposed with respect to each other, said pair of opposed bracket members each including a structure defining a plurality of bracket apertures, said opposed bracket apertures of opposed bracket members being in registry; said means for simultaneously reciprocating the seat means and the friction producing means pivotally lodges within a pair of opposed registered bracket apertures of said pair of bracket members; said means for simultaneously reciprocating includes a structure which partially defines a conduit with at least one conduit aperture; said exercising machine additionally comprising a handlebar including a rod integrally bound thereto and which is telescopically disposed within said conduit, said rod having a plurality of rod apertures which can be telescopically aligned with the conduit aperture in order to adjust the height of said handlebar with respect to the conduit; said exercising machine additionally comprises a cross brace member interconnecting said pair of side members of said frame, said brake shaft means has an end bound to the cross brace member and protrudes aslantly therefrom; said friction producing means comprises a wooden block means including an opening through which said brake shaft means extends in order for the wooden block means to reciprocally traverse the brake shaft means simultaneously to and in the same direction to the seat means being reciprocated; said exercising machine additionally comprising a tension adjusting means engaging the wooden block means for adjusting frictional tension of the wooden block means against the brake shaft means.
Claim 3
Dependent Claim 67 words
The exercising machine of claim 1 additionally comprising a metal container encasing said wooden block means; a pair of friction producing rods interconnected between the combined metal container-wooden block means and the conduit; and a pair of footrests which are threadably received by the means for reciprocating and protruding therefrom while pivotally lodging within a pair of opposed registered bracket apertures of said pair of bracket members.
