Abstract
When a computer keyboard is used for extended periods, fatigue and damage to the arm muscles may result from the lack of support for the forearms. The partial support that may be obtained from chair arms or desk edges may cause skin chafing as well as being somewhat restrictive. The subject invention provides bands suspending from the shoulders to the wrists or forearms. These adjustable bands provide support for the weight of the forearms, wrists and hands and also allow for completely free movement. Said adjustable bands would be attached to a light body harness either permanently or by means of hooks or other fastener devices.

SUPPORTS FOR ARMS W~EN TYPING AT KEYBOARD
This invention relate~ to elasticized bands susPendin~ from the shoulders to support the forearms and wrists.
It is common for the user of a desktop computer keybo~rd to work at said keyboard for extended periods. ~at.igue and mu~cular pain often result from the fact ~hat the weight of the arm is n~t supported between the shoulder and hand. In addition it may be only intermittently, or partially, supported at the hand extremity.
Alternately a chair with arms m~Y be used ~nd the user'~ forearm rested thereon, and ~ecau~e of the continuous wrist ~nd ~inger motion chafing results on the inside of the forearm. Again altern~tely, the wrist may be rested on the desk edge for support, and skin dama~ing chafing may result on the inside of the wrist. The aforementioned problems are experienced by both the amateur and professional keyboard user. In the case of the amateur the chair, desk and keyboard arrangement might be quite variable and improper. In the case of the professional the furniture arrangement may be improved but not perfectly for the individual user, and in addition the period of use will be longer. The resulting wear and tear on muscles, nerves and tendons can impair the functioning sf the h~nds, wrists, ~rms and shoulders. The risk of repetitive strain injury is generally greater with a common keyboard than a typewriter, partlY because computer users tend to type for longer uni~terrupted period~ and at greater speed. With the continuous adverse action of the aforementioned part~
216i~
of the body, often repetitive str~in in~ury occurs to the extent that this phenomenon is acknowled~ed as an occupational hazard.
The subject invention eliminates the aforementioned problems by providin~ support for the forearms and wri.st.s by m~an~ which transfer their weight directly to the shoulders. Said means of support would be adiustable bands made in whole or in part of ela.sticized material that would allow freedom of movement while carryin~ the wei~ht of the forearm~ thus eliminatin~ muscular ~train. Said bands would suspend from the front of the shoulders and would act as a slin~
around the forearms. Said bands would be attached by being permanently or detachably fastened to a cushioned, rigid or flexible body harness that would extend over the shoulders. The elasticized bands would extend from the front of the shoulder on each ~ide and would go down around the outside of the forearm and back up on the inside of the forearm. The extreme end of the elasticized band would be attached to a buGkle which would slide and lock on the band below the point of attachment to the body harness thus formin~ a type of adiusta~le sling for each arm. Said slin~ would ~e stiffened and cushioned at the lo~er curved end where it comes in cont~ct with the forearm by an unelasticized material which would be wider than the ela~ticized band to give a firm but not rieid support to the forearm~ This firm support would form a type of stirrup for the forearm to rest in ~ith no discomfort. Alternately, said stirrup could be of unelasticized semi-rigid material, suspended from the end of the elasticized band instead of having the elasticized band continued under the forearm~
2t 68~72 .~
The body harness to which the elasticize~ bands ~re connected at the front of the shoulders could be a one piece rigid yoke with a front horizontal element extending across the upper chest and having the ends turning upward to pass oYer each shoulder and S extend do~n the back. Said yoke would be of material pliable enough to bend to ad~ust to the shape of the shoulder~ of the user. Said yoke would be padded on the ma~or inferior surface so a.s to cu.shion all parts that come in contact with the body. Said yoke includin~ the paddinOE on the major inferior surface would be covered with fabric or plastic type material. The curved ends that pass over the shoulders ~ould extend down the back a .qufficient distance to ~pply to the shoulderblades the pressure resulting from the forward and downward pull on the body harne~s. Alternately, said yoke could be made in two piece-Y with the two ends of the divided horizontal element o~erlappin~
on the upper chest. This overlap would proYide for a width ad~ustment by the use of a bolt in a slot or other graduating ad~ustment fastener. Again alternately, the ela.sticized bands ~hich support the forearms could be attached at the front of the shoulders to a non-rigid body harness that would pass over the shoulders and extend down the back. Such a body harness would be of unela~ticized material which would rest on the shoulders ~nd be padded on the m~jor inferior surface to cushion the portion of the harness bearing on the shoulders. The left and right parts of .said harness ~ould cross or come close to~ether near the centre of the back and then form a loop at their lower end to accomodate a belt~ Said loop would be widened above the waistline where the belt passes through to accept the strain 2 ~ 6827~
of the upward pull of the rear parts of the flexible harness. The belt, integral with the harness, could be of elasticized or unelasticlzed material. Again alternately, the elasticized bands which support the forearms could be attached to discrete le~t and ri~ht shoulder Pieces at the front of the shoulders by means of a hook or other fastener to permit the elasticized bands to be detached from the body harness, and to permit their length adjustment~ In an alternate arran~ement of the non-rigid or ~lexible harness, the lower ends of the rear elements could be fastened, either together or separately, to a J shaped clip for attachment under an ordinary waist belt. Again alternately, the non-rigid harness could simply pass over the shoulders and around the neck.

In Figure 1 the elastiGized bands 1 suspend and thread through .slots 2 in the stirrups 3 and form loops bein~ returned attaGh to themselves by means of slidin~ and locking buckle~ 4. The elasticized bands 1 suspend from the bottom of the right an~le corners of a one piece rigid body harness yoke 5 which fit~ over the shoulders. The stirrups 3 would be of firm ~ut non-rigid material ~uch as Gushioned leather or felt and being wider than the elasticized bands 1 would elastically ~upport the forearms in a comfortable po.sition without restricting arm movement,~.
Fiyure 2 is a view of the rigid body harness ~ as it would be worn showing the elasticized bands 1 extending down from the front of the shoulders and passing through the slots 2 in the stirrups 3 to form loops around the forearms which are made adjustable for the comfort of the u~er by means of the ~liding and locking buckle.s 4 which are ~ewn or fastened by other mean.s to the extreme end of the bands 1. Said bands would be threaded through the buckle.s below the position where they are attached to the rigid body harness yoke 5.
Figure 3 shows the details of the rigid body harness yoke 5 in ~ cro~s sec~ion view. The ~tiffening eleme~t 6 is an aluminum fl~t which would be folded at right angles 7 to form a crossbar for a one piece rigid frame which Gould be adjusted by bending to fit the shoulders of ~he user. The elasticized band 1 is glued to the major inferior surface of the stiffening element where it folds over at ri~ht angle 7, ~o as to suspend from under the body harness. The ma~or 2 1 6 ~
inferior .sur~ace o~ the ~tif~enin~ element 6 is covered with a padding material 8. The stiffening element 6 and the padding material 8 would have a covering 9 of a fabric or pla.stic type material.
Figure 4 shows a ri~id two piece body harness with slotted adjustment. The crossover bar 10 would o~erlap the opposin~ bar 11.
The two bars 10 and 11 would be clamped together with a bolt 12 and nut 13. The bolt 12 would pass through a slot 14 in bar 10 thus allowing a separation-width ad~ustment of the shoulder bearing parts 5.
In Figure 5 the elasticized bands 1 suspend from the ~ront of the shoulders and thread through slots 2 in the stirrups 3 to form loops bein~ returned attach to themselves by means of sliding and lo~king buckles 4. The elasticized bands 1 would be attached at the ~ront of the shoulders to the extreme ends of shoulder straps 15 of a non-ri~id body harness that would pass over the shoulders and down the back. Said straps would extend down the back at an angle so as to ~oin in the centre of the back piece 16 then widen to form a loop 17 by ~oldin~ the extreme end of the widened material under itself and sewing or gluing it to form a loop through which a belt 18 would pa~s to fasten in the front of the body~ Said belt could be of elasticized or unelasticized material, and would be fastened by means of fa~tening 1~ which would allow length ad~ustment.
In Figure 6 the non-rigid body harness 15 is ~hown a~ it would be worn. It shows the elasticized bands 1 a~ they pass through 2 1 6~272 the slots 2 ln the stirrups 3 forming loops for the forearms and which are adjustable for the Gomfort of the user by means of the sliding and lc,cking buckles 4 which are sewn or fas~ened by other means to the extreme ends of the bands 1. Said bands would be threaded throu~h buckles 4 below the position where they are attached to the shoulder straps 15 of the non-rigid body harness. The belt 18 which ~ould pass through the loop 17 would come around the hody to fasten in a comfortable Position in front by means of fastening 1~
Fi~ure 7 shows the component.s of the non-rigid body harness in a cross section view. The elastlcized band 1 would be glued or fa~tened by some other means to extend from the end of the shoulder strap 15. Said shoulder strap would be of leather, fabric or other non-rigid material and would be covered on the major inferior surface over the ~houlder with a padding material 20. The shoulder strap 15 and the padding material 20 would be encased in a fabric or plasticized covering 21 over the shoulder area~ The shoulder straps 15 extend down the back and come together at the back piece 16~ then widen to form a loop 17 to accommodate a belt.
- Fi~ure ~ ~how~ an alternate type of stirrup 22 which would attach to the elasticized band 1 by means of an open rectangular ring 23 where the loop of the band 1 would be made throu~h the rectangular rin~ 23 to fasten to itself by means of a sliding and locking buckle 4.
Figure 9 shows a rigid body harness 24 which would have ~orward open J hooks 25 at its extreme ends at the ~ront of the 2 t 68272 shoulders ~rom which the elasticized band~ 1 would su.spend. Said body harness could be made of tubular or flat metal, plastic or other sultable material which could be ~ent to ad~ust to fit the user~ The ri~id frame of the body harness would extend down the back and would narrow and be bent at two approximate right angles to a narrow width.
This extreme lower, and rear, end of the ri~id frame would be encased in a leather or fabric material that would form a loop 2~ to accommodate a belt tas in Figure 5} to go around the body.
Figure 10 shows the rigid body harnes~ 24 with belt a~ it would be worn. The elasticized bands 1 would be anchored to the J
hooks 25 at the front of the shoulders by means of a triangular or rotated D shaped rin~ 27 whlch would be affixed to the extreme end of the elasticized bands 1. The belt 18 would pas~ through the loop Z6 to fasten in front ~as in Fi~re 6).
Fi~ure 11 shows the component~ of the ri~id body harne.ss 24 in a cross section view. The rigid frame 24 of tubular or fl~t material would have a forward open J hook 25 at the front of the shoulder. The major inferior surface of the ri~id body harness where it comes in contact with the body over the shoulder would be covered with a paddin~ material 28. The body h~rness 24 and the padded material Z8 would be ~o~ered with a fabric or plasticized material 29.
The ri~id body harness would extend down the back and the rear elements would terminate in a loop 26 (as in Figure 7~.
Figure 12 shows an alternate type of ela~ticized band construction where said band 30 ~ould have one end sewn or fastened by other means to a slidin~ and locking buckle 4 and threading through the slots 2 in the stirrup 3 to form the loop to support the forearm and then extend up around the triangular or rotated D ~haped ring 27 to thread through the buckle 4, In this construction the surplus end of the elasticized band 30 would extend beyond the sliding and locking buckle 4.
Fi~ure 1.3 shows a non-riEid bodY harness ~as in Fi~ure 5~
where the shoulder straps of unelasticized material 31 would extend down the back havin~ the lower end~ of the rear elements fa~tened, either to~ether or ~eparately, to a J shaped clip 32 for attachment under an ordinary waist belt.
Figure 14 sho~s the non-riOEid body harness 31 being worn (as in Fi~ure 6).
Figure 15 shows the components of the non-rigid body harness in a cross section view (as in Fi~ure 7~ but showing the unelasticized shoulder straps 31 without paddin~ and the J shaped clip 32 to attach to a belt.
Figure 16 is an altern~te non-rigid body harness ~as in Figure 13) where the shoulder straps of unelasticized material .31 would be attached to~ or be part of, a shoulder piece 33 which would horizontally join ~aid ~traps to~ether ~t the ba~k of the neck.
As depicted the proposed invention will effecti~ely and comfortably support the arm wei~ht by elastically suspendin~ the forearm.s while not re~tricting freedom of movement. Full versatillty of the arm supports for use in a variety of configuration~ ~nd by u~er~ of varyin~ build i~ provided.
The invention ha~ now been de.~cribed and any person havlng read lt will rapidly know how to modify it to obtain variations that are included in the ~cope of thi~ inven~ion.

Fi~ure 1.3 shows a non-riEid bodY harness ~as in Fi~ure 5~
where the shoulder straps of unelasticized material 31 would extend down the back havin~ the lower end~ of the rear elements fa~tened, either to~ether or ~eparately, to a J shaped clip 32 for attachment under an ordinary waist belt.
Figure 14 sho~s the non-riOEid body harness 31 being worn (as in Fi~ure 6).
Figure 15 shows the components of the non-rigid body harness in a cross section view (as in Fi~ure 7~ but showing the unelasticized shoulder straps 31 without paddin~ and the J shaped clip 32 to attach to a belt.
Figure 16 is an altern~te non-rigid body harness ~as in Figure 13) where the shoulder straps of unelasticized material .31 would be attached to~ or be part of, a shoulder piece 33 which would horizontally join ~aid ~traps to~ether ~t the ba~k of the neck.
As depicted the proposed invention will effecti~ely and comfortably support the arm wei~ht by elastically suspendin~ the forearm.s while not re~tricting freedom of movement. Full versatillty of the arm supports for use in a variety of configuration~ ~nd by u~er~ of varyin~ build i~ provided.
The invention ha~ now been de.~cribed and any person havlng read lt will rapidly know how to modify it to obtain variations that are included in the ~cope of thi~ inven~ion.
