Abstract

MULTI-PURPOSE EXERCISE MACHINE

ABSTRACT

This incention describes a multi-purpose machine designed to strengthen and exercise the machine of the back, torso, stomach and neck.

The machine consists of a seat mounted on a frame, with a moving arm pivoted on a vertical frame member and containing a padded bar against which a seated person can press with various portions of the anatomy in succession, in order to exercise different muscles.

Calisthenic exercises ~re ~ood for cas diovascular activity but do not provid0 a means o~ "loadin~ up" or stimulatin~ in a 6~fe ~a~ler the back or stomach muscles to grow and strengthen. Sit-ups on an illclined board or with the addition of weights will strel~then the stomacll ~uscles but pu~ great strai~ o~ ligaments al~d san causeiJlju.ry.
~eights ca~ be used to strefigthen certRin musc~es or the body te~. biceps~ but it is impossible t4 use wei~hts s~f~ly ~without the use of machines) to stre~g~hen bsck and stomach muscles.
Gym e~uipment, ineluding multi-purpo~ machines, such as rowing m~chin~s, ca~ be con~ected in ~uch fashion ~s to be oî li~ted use to the bac~ ahd stom~ch muscles, usually by mealls of stimul~ g other muscle groups (as in rowing~.

~ESCRIPTION OF THE lN~7~TION - PRE~D ~O~lME~T
See Fl~S. 1 and 2.
The machine consist3 of a metal frame ~1~ which re~ts on ~e floor A sea~ (2~ is centrally mounted on this frame for a person to sit on.A Yertical post (3) contains a bearine S4) for an arm t~) (moving in a ver~ical pl~ne) ~vhich is in~egral ~i~ the padded bar or bars (6). The r~nge of movemen~ of the moving arm is almost 90 degrees. The movi~g arm is connected via a cable ~7) running over three idler pulleys ~, 9 and 10) to a hinged notched spring ~rm (11). A large, horizontally mounted spring ~12) is attached at one end to ~he base îrame ( 1~ while the other end can bo ~anually moved fro~ one ~otch of the spring as~ (11) to a~o~er in order to vary ~he ~orce felt by the person pressing a~ainst the padded bar (6).
An impor~t feature consists Or using ~he speciflc ~eometf y o~ a l~near sprlng ~12~

ALTERNAIEEl~BODIMENT A
See Fig. 3 as well as Figs. I ~d 2.
The Alternate E~bodi~nent A describes the con~e~io3l Or ~he ~achin& f~om a to~soe30rsiser to a ne~ ~nd upper back ~ersiser.
In the basic torso machine padded bar ~ is rigidly at~ched ~o moYi~g ar~ (5~
the Alter~ate l~bodie~ne ~ A, pa~ded bsr (63 is attsched ~ sliding bar ( 13~ ~hich slldes inside moYement a~m ~5) a~d is rigid~ clamped there~ by clamp S1~). This allows ~ hig~er ~ositio~ for padded bar (6~, ellabl~g a person to press again~t it with his or her head i~ order ~ eYercise tho ~eck ~d upper be~ck muscles.
To operate this feature, a per~n would set a lower ~alue o~ sprin,~ Çorce aQd ~rhile se~ted in t~e bac~ position, preæ ~ith the bac~ of ~is hesd agai~st the padded bar (6) so ss ~ e~ercise the ~leck a~d upper ~ac~ muscles. ~r several rep~ o~s he would then rotate 90 degrees on his seat and press item (6~, with t~e 3ide of his 3hea~ e~
rotate ag~in o~ the se~t ta the stomach position and press O]~ he padded b~r with his f~rehead. ~ ally, after several repetitions, he wQul~ rotste ~0 degrees o~l the seat by sgraddLi~g t,he vertissl post (33 s~d ~vould press ~vith ~e right sid~ o~ his he~d aga,~nst the padded bar (~.

ALIE~ATE E~IBODIMENT B
See FIG.4 as well as FIGS. I and 2.
The Alterna~e Embodimen~ B ~1 o describes the conversion of ~he machihe from a ~orso to a neck snd upper ~a~k exer iser ~u~ accomplishes ~hal by means of a separa e a.t~chment.
In lhe basic ~orso machine, padded bar (6) is rigidly a~tached to moving arm (5). In ~hc A1~crna~e Embodimenl B, an addi~ional L-shaped attachment (15) is adjustablyat~ached ~o moving arm (5) and clamped there~o by means Or clamp (14). This a~tachmenl (15) conlains a padd~d cushion (16 ) The operation of ~is feature is iden~ical to that described under Alterna~e Embodiment A.

Claims

CLAIMS.

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1. A multi-purpose machine capable of exercising and strengthening the muscles of the lower back, by having a person. while seated, press with his or her back against a padded bar or bars connected to a spring via a notched lever, with each notch permitting a different spring force setting, said notched lever being connected via a cable to the bottom of the pivoting padded bar, the geometry being so chosen as to compensate for the increasing force of the spring as the padded bar is depressed, by decreasing the effective moment arm of the two said levers, the net effect being an essentially constant force at the padded bar over the full range of travel.

2. A machine as defined in Claim 1 but used for exercising and strengthening the abdominal and pelvic muscles, accomplished by having the person sit at 180 degrees to the position described in Claim 1 and pressing the padded bar with his or her chest or forward part of the shoulders.

3. A machine as defined in Claim 1 but used for exercising and strengthening the other muscles of the torso, achieved by having the person sit at 90 degrees to the position descried in Claim 1 above and pressing the padded bar with his or her underarm or upper arm, first the right side then the left side in succession.

4. A multi-purpose machine capable of exercising and strengthening the extension muscles of the upper back and neck by having a person, while seated, press with his or her back of the head against a padded bar connected to a spring via a notched lever, with each notch permitting a different spring force setting, said notched lever being connected via a cable to the bottom of the pivoting padded bar, the geometry being so chosen as to compensate for the increasing force of the spring as the padded bar is depressed, by decreasing the effective moment arm of the two said levers, the net effect being an essentially constant force at the padded bar over the full range of travel.

5. A machine as defined in Claim 4 but used for exercising and strengthening the flexion or forward muscles of the neck, accomplished by having the person sit at 180 degrees to the position described in Claim 4 and pressing the padded bar with his or her forehead.

6. A machine as define in Claim 4 but used for exercising and strengthening the side muscles of the neck, achieved by having the person sit at 90 degrees to the position described in Claim 4 above and pressing the padded bar with his or her side of the head, first the right side then the left side in succession.
