Abstract
The subject invention provides a triceps exercise machine which minimizes the torque on a user's shoulders throughout the range of motion. The exercise machine applies a pulling force to the user's arms, the magnitude and direct of which remains substantially constant, such that as the users' hands rotate about the user's elbow the effective toque on the user's elbows and shoulders remains substantially constant.
Claims20
An exercise machine for exercising a user's upper arm muscles comprising:
- a frame;
- and
- an input assembly pivotally connected to the frame and engagable by the user, the input assembly imparting an effective torque on the user's shoulders, the effective torque on the user's shoulders remaining substantially constant through the range of motion.
An exercise machine for exercising a user's upper arm muscles comprising:
- a frame;
- an input assembly including a linkage assembly pivotally connected to the frame, a pair of trailing arms pivotally connected to the linkage assembly, and a pair of handles connected to the pair of trailing arms opposite that the linkage assembly, such that the handles are positioned above the user's shoulders;
- and
- a resistance mechanism operably connected to the input assembly.

An arm extension machine for exercising the upper arm muscles, comprising:
- a frame disposed to be placed on a surface,
- a load mechanism providing a load,
- a seat and a backrest coupled to the frame, each defining a common plane of symmetry, the plane of symmetry being perpendicular to the surface,
- first and second arms coupled to the frame and oriented substantially parallel to the plane of symmetry and the surface, each having
- a proximal and a distal end portion, and
- a handle disposed at the proximal end portion,
- first and second linkages, each linkage having a first pivot and a second pivot,
- the distal end portion of the first arm being rotatably coupled to the first linkage to
- rotate the first arm about the first pivot of the first linkage to define a first plane of motion, and to
- rotate the first arm about the second pivot of the first linkage to define a second plane of motion,
- the first plane of motion being substantially perpendicular to the surface and parallel to the plane of symmetry, the second plane of motion being substantially parallel to the surface and perpendicular to the plane of symmetry, and
- the distal end portion of the second arm being rotatably coupled to the second linkage to
- rotate the second arm about the first pivot of the second linkage to define a third plane of motion, and to
- rotate the second arm about the second pivot of the second linkage to define a fourth plane of motion,
- the third plane of motion being substantially perpendicular to the surface and parallel to the plane of symmetry, the fourth plane of motion being substantially parallel to the surface and perpendicular to the plane of symmetry.
