shown, where the keys are separated into two distinct sections-:~
the left-hand and the right-hand sections. This construction`
is well designed but it can not provide changin~ the position, of arms wit~ respect to the keyboard. Basically the typing position of hands and wrists remains the same as in a traditionally set up keyboard. In this case computer's keyboard can not be brought parallel to left and right side of-~ the body, nor it can be brought to the arms supports of the, -~ 35 armchair. Also the keyboard descri~bed at thls article can not~
- be used in lying position by handicapped people who hare - difficulty in sitting up right, a,s a result of suffering from:

a possibility to work from full sitting to full lylng position~
~- with full support of the body and especially wrists and arm~
'~ during the time of typing. The present inventlon allows the~
' ' computer operator to regulate the angles of whole one pie ; keyboard as well as divide the keyboard into two parts and i- 10 bring the'keyb-oard parts closer to his or her body sides, ~here~
-'' the position and angles of the keyboard parts may be regulate This in turn may eliminate body stresses, as well as any computer work relating injuries, specially back and wrist ~-~ ' in)urles. ~,..
This invention proposes different distribution of human'-body weight on the armchair. This is executed by redesigning~
- computer's keyboard and secretary's armchair to obtain~
'' possibility of working with the keyboard placed on top of the `~
desk as well as with the keyboard placed on arms supports of '' 2Q the armchair. The most preferable solution is the armchalr with regulated supports for legs and the rest of th`e body, with .
fully~supported back, arms, and wrists'~ The armchair permits'~
working in classical secretary position, where both hands lie`
. on the desk. Also it permits to work 'from the half lying to "

At this position-whole weight of the body is distributed to a much larg'er area ~' 30 of an armchair than in a classical secretary position ~hat in:
turn can greatly reduce muscle tension and body stresses. To permit changes with redesigned armchair, we propose redesigning of the keyboard. This invention proposes to make a keyboàrd composed of two parts which can be ea5ily mo~ed apart or `
assembled together as a whole one piece traditional keyboard.
-- These two parts can be made as`separate and independent left - and right-hand operated parts which can be positioned on thecorresponding to them arms supports of the armchair.

Two separate and independent left-and rlght-hand operat ~ `
parts of the keyboard, have been connected together to obtalA~
whole keyboard as it is commonly used no~. They have bee~`:
- connected together by using a female and male multi connecto~.-.

of the keyboard. After that a whole one piece,'two hand8~
operated computer's keyboard with all circuits connected inside ~ `
' ` of the keyboard, have been obtained. And this keyboard looks.
- ' l~ike traditional whole one piece desktop computer keyboard. At:
this example keyboard is lying on the top of desk and computer ~' operator has a traditional position with arms and wrists supported by the top of the desk.
Example 2.
- The method and accommodation for transforming desktop keyboard to the arms supports of the armchair.
; - Computer operator can lie in almost horizontal position ~ln ~ ' the armchair, in'a similar manner as a passenger in the - airplane, from slipping position through the intermediate to a;~
' ' classical secretary position, as his/her back, arms, wrists and':
' 35 legs are fully supported. The whole traditional looking -::~ keyboard is taken apart to obtain two separate and independent '' -left and right-hand operated parts. This is done by disconnecting the multi connector between these two parts.
After that the two parts of keyboard are placed on their`
corresponding arms supports of the armchair. To make it ^
possible additional two plugs (male and female~ are used, where one of these plugs i5 located on the bottom of the left-hand , operated part of keyboard, and the'other plu~ ls located on the left arm support of the armchair. The left-hand operated part of keyboard is positioned on the top of it's corresponding`arm support of the armchair, with simultaneous connection of plug .

positlon operator's wrists and arms are lylng at the arm supports of the armchair. As a result, left hand's fingers aré,'~
placed on the left-hand operated part of the keyboard and righ~
hand's fingers are placed on the right-hand operated part of the keyboard. At the same time arms and wrists are fully..-~supported by arms supports of the armchair or armchair-like~

positioned close together on t`he keyboard without any support.,', `;
, at this example operator'.s hands are positioned on the left and~
right arms supports almost parallel to the body sides. This'~
position is very relaxing as the back and the rest of the body"'-.;' is fully supported. This position contributes.to elim;nation..~'~..' ~-. 30 ~of muscle tension , f~

electrical connection between left and right-hand operat pieces is executed by pushing female and male plugs together~
similar way as plugging telephone cord to the plug on the wall, ~
To make it possible, one piece of cable ended with a plug ~''L' - placed inside of the socket and another plece of cabie end~ .
- with a plug is~placed in the ball of separabie ball-soc ~ ,'~, , joint. ' ~ ~`,,t ,~ 15 Example 4 ' Computer work place wherein left and right-hand operated piece~

supports of the armchair and connection between those parts is~
execu-~ed by using a bali-socket joint.-For pla,in~ left and right-hand operated pieces of thé ,~, ;keyboard on the corresponding arms supports, each`piece of, -keyboard has it's own socket on the bottom, where each socket,,, has an electric cable ended with a plug. On the corresponding, 25- places each arm support of armchair has t's own ball with a-~piece of electric cable ended with a plug. By pu-shing together ~, , , socket with a plug from the keyboard piece to~the corresponding~ '' ; - ' arm sùpport (equipped with the ball that contains a cable ended'~
- with a plug), a flexible and adjustable ball-socked joint ,'`~
- i 30 between a piecè of the keyboard and an arm support of the~', armchairt can be obtained. After finding a preferred angle,,~
~, the ball-socket joint can be solidified by tlghtening a screw.
, As a further improvement, computer and computer screen can also be incorporated to the armchair. Especlally it is pteferable~-3S to attach computer screen to a movable mechanical arm or other'','devices which ar'e able to follow changes of operator's , position. , Methods shown in all of the examples are extremely useful for rehabilitation of the handicapped people. ?hese methods - , , can put back to work millions of partly paralyzed people and those suffering from muscular dystrophies, disc disease, spinal , cord disaster and similar sickness. Despite of thi8 fact, this method can create it's own market for healthy people who suffer fatigue from working long hours on the computer. The examples presented above represent a set of preferable embodiments.

which may be exposed after pieces of keyboard are removed ~r ~ ~,I,',,,~é ' arm support and assembled together as a whole one piec-~y`~ ~' desktop. These covers may ,be used when we decide to mov~
keyboard from armchair to secretary desk. As an additiona~
15~ improvement, arms and wrists supports of the armchair can ~ ~
