ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a readily movable, storageable and use convertible device adapted for selective human upper torso conditioning and development.
BACKGROUND OF THE INVENTION
The need for practical and affordable devices suitable for muscle toning and body conditioning is a long established one. There are a large variety of exercise devices, many of which focus on conditioning just one set of muscles, but only a few which are adapted to toning of two related sets of muscles; for example, biceps and triceps, or lats and pectorals. Among the needs are an exercise machine which, in overall concept, can make use of plural positions on a grippable mast component for effecting several corresponding articulations. There remains a need for a machine that is relatively compact, very versatile, and easily storable.
Fitzpatrick 5,037,090 (1991) is to a free-standing exercise device having two support components, serving either as a posture sitting stool
8
or a kneeling stool
7
. It uses a vertical mast
2
and a handle-bar type of pivoted lever
10
, with the latter working against an obverse mast-side resistance means
13
. Each of the two positions for seat
7
provide for certain exercises, all of which require a user to either stand or kneel on the seats
7
/
8
. The range of exercises available with the device are very limited, affording only three basic exercises: shoulder press, lat pull down, and tricep extension. The present invention has two features: variable lever settings and sliding sleeve, which makes this device at least twice as versatile as Fitzpatrick's . The largest difference between the present invention and Fitzpatrick's is that the present invention use of cam affords both vertical and horizontal exercise motions. Fitzpatrick's invention, is only capable of vertical motions. Earlier mechanism does not provide the broad array of exercises that are doable with the present invention, specifically: the lat pull down, the chest press, the biceps curl, the shoulder press and upright row, a shoulder shrug, and the triceps extension (all depicted in composite FIG.
5
). Nor is it possible with the previous device to do the biceps curl of present
FIG. 4
, which is afforded by the present device. Thus, the range of available exercises with the present device substantially exceed those of the exercise device of Fitzpatrick '090.
SUMMARY OF THE INVENTION
The present invention works completed muscles of upper body, which is very rare for such a versatile, compact, easily transportable, and storageable, exercise machine. Thus, it is a principal object of the invention to provide a single portable device which has alternate modes of operation, each mode being for muscle loading use of the upper limbs, including various arm extension exercises.
Another object of the invention is to provide a hand grippable, lever subassembly and support bracket, and a variable position means, which is mounted on a mast component, which can be slidably translated into an alternate modes of operation for effecting different exercises.
Another object of this invention is to provide a unique cam lever, which allows the hand grippable bar to move in two distinct motion planar paths; vertical and horizontal, respectively, affording greater versatility and a complete upper body workout.
It is still another object of the invention to provide a machine, which is both portable and readily storable, and which focuses on the muscle sets of the upper body.
It is still another object of this invention to provide a dual effect, resisting hydraulic cylinder, providing resistance in both upward and downward directions during shoulder press exercises to exercise the latissimus-dorsi muscles.
A still further object is to provide a leg squat exercise when the variable position means is at the lowermost position on the mast.
It is still another object of the invention to provide a portable machine, which includes an adjustable-position, channel-containing subassembly that permits at least eight exercises from a single supporting mast which is anchored to its supporting floor chassis.
It is still another object of the invention to provide an uncluttered configuration of components having great versatility.
