Folding rear drive elliptical

摘要

Embodiments of an elliptical exercise machine are provided including an elliptical exercise machine having a rear mechanism that is foldable or collapsible from an operating position to a storage position. In one embodiment, the elliptical machine includes a first assembly pivotally coupled with a second assembly. The first assembly includes a first frame member, a rear rotational mechanism and first and second foot supports operably coupled with the rotational mechanism. The second assembly includes a second frame member, a first reciprocating arm and a second reciprocating arm. The second assembly may be displaced relative to the first assembly from an operating position to a storage position without having to alter the operational relationships of the components of the first assembly and without having to alter the operational relationships of the components of the second assembly.

1. An elliptical exercise machine comprising:
a first assembly comprising:
a first frame member;a rear rotational mechanism associated with the first frame member;a first foot support member having a first end and a second end, wherein the second end of the first foot support member is pivotally coupled to a portion of the rotational mechanism;a second foot support member having a first end and a second end, wherein the second end of the second foot support member is pivotally coupled to a second portion of the rotational mechanism; a second assembly comprising:
a second frame member; a pivot structure coupled between the first frame member and the second frame member;a first reciprocating arm having a first end and a second end, wherein the second end of the first reciprocating arm is directly and pivotally coupled with the first end of the first foot support and the first reciprocating arm is directly and pivotally coupled to the second frame member;a second reciprocating arm having a first end and a second end, wherein the second end of the first reciprocating arm is directly and pivotally coupled with the first end of the first foot support and the first reciprocating arm is directly and pivotally coupled to the second frame member;wherein the second assembly is pivotally displaceable between a first position and a second position relative to the first assembly; wherein the first frame member, the rotational mechanism, the first foot support member and the second foot support member maintain their operational relationships with each other while in both the first position and the second position; and wherein the second frame member, the first reciprocating arm and the second reciprocating arm maintain their operational relationships with each other while in both the first position and the second position; and wherein the pivotal coupling between the first foot support and the first reciprocating arm defines a first pivotal axis and the pivotal coupling between the second foot support and the second reciprocating arm defines a second pivotal axis; wherein the pivotal coupling between the first frame member and the second frame member defines a third pivotal axis; and wherein the first pivotal axis, the second pivotal axis and the third pivotal axis remain aligned during displacement of the second assembly between the first and second positions.
