Power wheel chair

1. A power wheel chair having an improved motion control, comprising:

a frame having a right frame section and a left frame section extending between a front frame end and a back frame end;

said frame including a right and left upstanding portion extending in a generally vertical direction; a seat mounted to said frame for transporting an occupant;

a right and a left caster wheel located in proximity to said front frame end adjacent to said right and left frame sections, respectively;

a right and a left drive wheel located in proximity to said rear frame end adjacent to said right and left frame sections, respectively;

a motor for driving said right and left drive wheels through a differential gearbox;

a right and a left handle connected to said right and left upstanding portions, respectively,

said right and left handles and a left hand gripping portion;

said right and left handles extending generally horizontally and backwardly from said back frame end;

a journal for rotating one of said right and left handles about a generally vertical axis;

a journal lock for locking one of said right and left handles about said generally vertical axis;

said journal lock locking said one of said right and left handles in a first rotation position whereat said one of said right and left handles is in generally perpendicular alignment with an axle driving said right and left drive wheels through said differential gearbox;

said journal lock locking said one of said right and left handles in a second rotation position whereat said one of said right and left handles is in generally parallel alignment with an axle driving said right and left drive wheels through said differential gearbox; and

an electronic control having a control lever located in proximity to one of said right and left handles for enabling the attendant to controlling the speed and braking of the power wheel chair.

2. A power wheel chair as set forth in claim 1 , wherein one of said right and left handles includes a vertical adjustment device for adjusting a vertical position of said one of right and left handles; and

Said one of said right and left vertical adjustment devices having an adjustment lock for securing said one of right and left handles in a vertical position.

3. A power wheel chair as set forth in claim 1 , including a battery cassette receiver secured to said frame;

battery cassette receiver having cassette receiver contacts connected to said frame;

a battery cassette having a battery connected to battery cassette contacts; and

said battery cassette being insertable into said battery cassette receiver for interconnecting said battery cassette contacts with said cassette receiver contacts for powering the power wheel chair.

4. A power wheel chair as set forth in claim 1 , including a battery cassette receiver secured to said frame;

battery cassette receiver having cassette receiver contacts connected to said frame;

a battery cassette having a battery connected to battery cassette contacts;

said battery cassette being insertable into said battery cassette receiver for interconnecting said battery cassette contacts with said cassette receiver contacts for powering the power wheel chair;

a remote battery cassette receiver located remote from the power wheel chair;

said remote battery cassette receiver having remote receiver cassette contacts connected to a battery charger; and

said battery cassette being insertable into said remote battery cassette receiver for interconnecting said battery cassette contacts with said remote cassette receiver contacts for charging said battery.

5. A power wheel chair as set forth in claim 1 , wherein said first rotational position aligns said one of said right and left handles extends generally backwardly and perpendicular to said axle driving said right and left drive wheels through said differential gearbox.

6. A power wheel chair as set forth in claim 1 , wherein said second rotational position aligns said one of said right and left handles extends generally outwardly and parallel to said axle driving said right and left drive wheels through said differential gearbox.

7. A power wheel chair as set forth in claim 1 , wherein said journal rotates said one of said right and left handles about a generally vertical axis into a third rotational position whereat said one of said right and left handles extends generally forwardly and perpendicular to said axle driving said right and left drive wheels through said differential gearbox.

8. A power wheel chair as set forth in claim 1 , wherein said journal rotates said one of said right and left handles about a generally vertical axis into a fourth rotational position whereat said one of said right and left handles extends generally inwardly and parallel to said axle driving said right and left drive wheels through said differential gearbox.
