  • Patent number: 9867745
    Abstract: A lift system 100 may comprise two sets of two pistons with each set of pistons attached to an upper cross bar 210 and a lower cross bar 275, with the lower cross bar having distal ends comprising distal insertion areas 276 with the distal insertion areas passing through a first void 241 defined within a wheelie bar 240 and the distal insertion areas 276 reaching further to move a wedge bar 270. To lift a patient from a lowered position, a piston moves a lower cross bar 275 which in turn moves a wedge bar 270 into a wedge 280, causing the lower cross bar to break out of plane with a top bar 205. The use of two wheelie gears 220 ensures that the lift remains horizontal even if piston forces are not uniform. The use of four top bars 205 allows for folded storage.
    Type: Grant

  • Patent number: 9861538
    Abstract: A mechanical lift features the low profile of a traditional wood and cloth cot stretcher allowing patients to be easily rolled or moved upon a flat surface. An integrated mechanical lift system then lifts a patient to a raised position without need for manual lifting. The lift allows patients to be moved and transported without back strain to health care workers or first responders. The lift may be raised by the mechanical movement or expansion of a piston.

  • Patent number: 9579240
    Abstract: A mechanical lift features the low profile of a traditional wood and cloth cot stretcher allowing patients to be easily rolled or moved upon a flat surface. An integrated mechanical lift system then lifts a patient to a raised or seated position without need for manual lifting. The lift allows patients to be moved and transported without back strain to health care workers or first responders. The lift may be raised by the mechanical movement or expansion of a piston. A seat plate 420 may rest upon a non-tilting seat strut 310 and become a seat as the lift rises. During the lifting process, a back plate 400, attached to a back strut 205 gently rises to place the patient in a seated position as a leg plate 440 lowers.
