Claims18
An all purpose wheelchair to permit a user to be self sufficient and to permit a user to move from a chair type support to a horizontal bed type support with the horizontal bed type support being vertically positionable comprising:
- a frame;
- a backrest for supporting the back of a person, said backrest pivotably connected to said frame;
- a first set of extendable legs connected to said backrest;
- a seat cushion located on said frame for supporting the posterior region of a person;
- a legrest for supporting the legs of a person;
- a backrest pivoting mechanism connected to said backrest;
- a second set of extendable legs connected to said backrest and said frame;
- a first power mechanism for pivoting said backrest from a horizontal to a vertical position or from a vertical to a horizontal position;
- and
- a source of power for activating said first power mechanism so that when the wheelchair is in the chair type support position the powering of said first mechanism causes said backrest to pivot from the vertical to the horizontal position and to extend said first set of legs and said second set of legs to form engagement with a support surface to permit the vertical raising of a user on said seat cushion and said backrest to thereby permit a user of the wheelchair to be positioned at the same level of a bed so the wheelchair user can be transferred from the wheelchair to the bed withoout anyone having to lift the wheelchair user.
An all purpose wheelchair to permit a user to be self sufficient and to permit a user to move from a seating position to a horizontal position with the wheelchair being vertically positionable comprising:
- a frame;
- a backrest for supporting the back of a person at various postions, said backrest pivotably connected to said frame;
- a first set of extendable legs connected to said backrest;
- a seat cushion located on said frame for supporting the posterior region of a person, said seat cushion having an opening therein to permit placement of a bedpan below the opening in said cushion;
- a backrest pivoting mechanism connected to said backrest;
- a second set of extendable legs connected to said backrest and said frame;
- a power mechanism for pivoting said backrest from a horizontal to a vertical position or from a vertical to a horizontal position and for simultaneously extending or contracting said legs;
- a control module to permit a user located in the wheelchair to control said power mechanism;
- and
- a source of power, said source of power controllable by said control module so that when the wheelchair is in the position to support a user in a sitting position the powering of said backrest pivoting mechanism causes said backrest to pivot from a vertical to a horizontal position and to simultaneous extend said first set of legs and said second set of legs to form engagement with a support surface to thereby elevate a user on said seat cushion so that a user of the wheelchair can be positioned at the same level of a bed to facilitate transfer of the wheelchair user from the wheelchair to a bed.
