Hospital bed power-assist
View Patent ↗The present invention, in one embodiment, is a device for moving a hospital bed. The device comprises a body, a motor driven wheel coupled to the body, and a hitch coupled to the body and adapted for engaging the hospital bed. Finally, the present invention, in yet another embodiment, is a method for moving a hospital bed with a motorized device. The method comprises maneuvering the device into position next to the hospital bed, hitching the device to the hospital bed, and moving the hospital bed with the device.
1. An apparatus for moving a hospital bed equipped with wheels, the apparatus comprising:
a body including a plurality of wheels coupled to the body, wherein at least one of the wheels is a motor driven wheel and at least one of the wheels is a free turning wheel adapted to stabilize the apparatus; and
a hitch mechanism including a pair of engagement elements adapted to engage the wheels of the hospital bed, wherein each engagement element is a wheel lock comprising a block including a sloped wheel approach leading to a wheel groove for receiving one of the wheels of the hospital bed, wherein the hitching mechanism is adapted so the engagement elements are horizontally displaceable relative to the body.
2. An apparatus for moving a hospital bed equipped with wheels, the apparatus comprising:
a body including a plurality of wheels coupled to the body, wherein at least one of the wheels is a motor driven wheel and at least one of the wheels is a free turning wheel adapted to stabilize the apparatus; and
a hitch mechanism including a pair of engagement elements adapted to engage the wheels of the hospital bed, wherein each engagement element is a wheel lock comprising a block including a sloped wheel approach leading to a wheel groove for receiving one of the wheels of the hospital bed, wherein the hitching mechanism is adapted so the engagement elements are vertically displaceable relative to the body.
3. An apparatus for moving a hospital bed equipped with wheels, the apparatus comprising:
a body including a plurality of wheels coupled to the body, wherein at least one of the wheels is a motor driven wheel and at least one of the wheels is a free turning wheel adapted to stabilize the apparatus; and
a hitch mechanism including a pair of engagement elements adapted to engage the wheels of the hospital bed, wherein each engagement element is a wheel lock comprising a block including a sloped wheel approach leading to a wheel groove for receiving one of the wheels of the hospital bed, wherein the hitching mechanism is adapted so the engagement elements are displaceable forwardly and rearwardly relative to the body.
4. An apparatus for moving a hospital bed equipped with wheels, the apparatus comprising:
a body including a plurality of wheels coupled to the body, wherein at least one of the wheels is a motor driven wheel and at least one of the wheels is a free turning wheel adapted to stabilize the apparatus; and
a hitch mechanism including a pair of engagement elements adapted to engage the wheels of the hospital bed, wherein each engagement element is a wheel lock comprising a block including a sloped wheel approach leading to a wheel groove for receiving one of the wheels of the hospital bed, wherein the hitching mechanism is adapted so the engagement elements are tiltable relative to the body.
5. An apparatus for moving a hospital bed equipped with wheels, the apparatus comprising:
a body including a plurality of wheels coupled to the body, wherein at least one of the wheels is a motor driven wheel and at least one of the wheels is a free turning wheel adapted to stabilize the apparatus; and
a hitch mechanism including a pair of engagement elements adapted to engage the wheels of the hospital bed, wherein each engagement element is a wheel lock comprising a block including a wheel groove for receiving one of the wheels of the hospital bed and a gate for preventing the hospital bed wheel from exiting the groove, wherein the hitching mechanism is adapted so the engagement elements are horizontally displaceable relative to the body.
6. An apparatus for moving a hospital bed equipped with wheels, the apparatus comprising:
a body including a plurality of wheels coupled to the body, wherein at least one of the wheels is a motor driven wheel and at least one of the wheels is a free turning wheel adapted to stabilize the apparatus; and
a hitch mechanism including a pair of engagement elements adapted to engage the wheels of the hospital bed, wherein each engagement element is a wheel lock comprising a block including a wheel groove for receiving one of the wheels of the hospital bed and a gate for preventing the hospital bed wheel from exiting the groove, wherein the hitching mechanism is adapted so the engagement elements are vertically displaceable relative to the body.
