Emergency lift and transport system
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.
1. A lift comprising:
a) a top bar ( 205 ) fixedly attached to a wedge ( 280 ) and the top bar pivotally attached to a first wheelie gear ( 220 ), the first wheelie gear attached to two wheelie bars ( 240 ), each wheelie bar comprising a longitudinal body ( 245 ) with the longitudinal body defining a first longitudinal void ( 241 ) the first longitudinal void of the wheelie bar retaining a lower cross bar ( 275 ), with the longitudinal void allowing the lower cross bar to slide within the wheelie bar;
b) a wedge bar ( 270 ) attached to a distal end of the lower cross bar, the wedge bar comprising a first end having a cambered edge ( 271 ).
2. The lift of claim 1 further comprising at least one piston attached to the lower cross bar and an upper cross bar ( 210 ).
3. The lift of claim 2 wherein the wedge comprises an angled edge ( 281 ), the angled edge comporting to the cambered edge of the wedge bar.
4. The lift of claim 2 further comprising a cylinder rod clevis ( 267 ) attached to the lower cross bar and the piston.
5. The lift of claim 2 further comprising a cylinder ( 260 ) attached to the piston.
6. The lift of claim 2 wherein the piston is attached to an upper cross bar ( 210 ).
7. The lift of claim 2 wherein one or more wheels are attached to each of the wheelie bars.
8. The lift of claim 2 wherein a skid plate ( 450 ) is attached to each of the two wheelie bars.
9. The lift of claim 2 with a second wheelie gear in geared connection to the first wheelie gear.
10. The lift of claim 2 with four pistons, with each piston attached to a lower cross bar and a upper cross bar.
