• the straps 118 and clips 91 are length adjustable, such that the intermediate elevated position does not need to be located at a precise elevation since any slack in straps 118 can be taken up by shortening the straps 118.
• FIG. 3 shows the support arms 68 and 69 raised upwardly from the intermediate position and toward the high position, which lifts the stretcher 100 from the bed surface 111. In this position, the transporter 10 can then be moved from this first bed location, and moved to another location such as another bed or a treatment area.
• the stretcher 100 can also be oriented in an in line position wherein the centerline or length of the stretcher 100 is in line with or generally parallel with the front to back direction of the transporter 10 although the flexible straps 118 do not require absolute alignment.
• the head end 103 of the stretcher 100 is positioned near the transporter's front end 19. This might be desirable for loading or unloading a patient 18 from the head end of the bed 110.
• Fig. 4 shows the transporter 10 in a lowered position closer to the floor, which may be desirable to pick up or drop off a patient from a floor surface or other support located below the height of the bed surface 111.
• Fig. 7 shows the stretcher 100 and patient 18 in the high position with the support arms 68 and 69 raised.
• FIG. 8 shows the stretcher 100 in the low position at floor level.
• Fig. 9 shows the transporter 10 moved away from the patient 18 who is rested on a support surface.
• the straps 118 are disconnected by disengaging the clips 91 from the support arms 68 and 69 and slots 90.
• Figs. 10-13 in turn show the stretcher 100 suspended from the support arms 68 and 69 in the transverse orientation.
• the transporter 10 is in a partially elevated position between the low position and high position.
• Figures 14 and 15 show the stretcher 100 suspended from the support arms 68 and 69 in the in-line orientation.
• the flexible suspension straps 118 may also have enough length to allow the stretcher to be rotated about a vertical axis as generally indicated by reference arrow 120 in Fig. 12.
• the stretcher 118 is shown in the transverse orientation, but the flexible straps 118 allow the foot end of the stretcher to be swung in direction 120, i.e. counterclockwise in Fig. 12, so that the stretcher 100 is repositioned to the inline position. This results in twisting and spiraling of the straps 118 but allows the stretcher to be rotated to accommodate different physical conditions in a room.
• the stretcher 100 is in the inline orientation but can be swung either clockwise or counterclockwise as indicated by arrow 121.
• Figs. 23 and 24 further illustrate the transporter 10 with the manual unpowered wheels 43-1 (see also Figures 2 and 3) . It will be understood that this transporter variation functions the same as the powered transporter variation described above. Generally, the transporter 10 can be positioned over a patient 18 in an inline position and then lifted as seen in Fig. 24.
• Figs. 25 and 26 show a rotatable pedestal 125 having a base 126 and a rotatable support tray or turntable 127 that is configured to support the stretcher 100 thereon.
• the base 126 has
• upstanding legs 128 that typically sit on a floor or other support surface and a top panel 129 that supports a swivel bracket 130 that supports the turntable 127 thereon.
• the turntable 127 has side walls 131 and a central pocket 132 that receives the stretcher 100 therein.
• transporter 10 can be moved away from the patient 18 and stretcher 100 as seen in Fig. 29.
• stretcher 100 can be rotated to the transverse orientation as indicated by reference arrow 133. Thereafter, the transporter 10 can be moved over the patient 18 (Fig. 32) for subsequent lifting (Fig. 33) of the patient 18.
• the pedestal 125 is manually removable and movable within the building space and eases in the reorientation of the patient between the
• Figures 34-43 illustrate the transporter 10 provided in combination with a vehicle trolley 150, wherein Figure 34 is a perspective view of the vehicle trolley 150 mounted in a cargo space 151 of a vehicle 152.
• the vehicle trolley 150 can be installed in the vehicle 152 for ready loading of the lift-transfer device 10 therein.
• the system uses the extension and retraction of the lifting columns 30 and 31 to raise and lower the lift-transfer device 10 on the vehicle trolley 150 and then the vehicle trolley 150 is operated to slide the lift-transfer device 10 into the cargo space 151.
• Figures 34-37 generally illustrate the vehicle trolley 150 with a base frame 154 and pivotable support gate 155 that may be swung between and open an open position
• the base frame 154 includes extendible side rails 156 joined together by cross rails 157, which further include mounting plates 158 for fastening the base frame 154 to the vehicle bed 152A.
• the side rails 156 are formed of telescoping first and second rail sections 156-1 and 156-2 which are slidably joined together to allow the length of the side rails 156 to be extended out of the cargo space 152.
• the support gate 155 is formed of a U-shaped frame member 158 having a cross rail 159 and side legs 160 which are joined by a brace member 161.
• One side leg 160 is pivotally connected to one first rail section 156-1 by a hinge assembly 162 ( Figure 38) to allow swinging or pivoting of the support gate 155 about a pivot pin 163 between the open and closed positions .
• a releasable latch 164 is also provided to help hold the support gate 155 in the closed position within the vehicle 152 during vehicle movement.
• the other side leg 160 on the side opposite to the hinge assembly 162 includes a releasable latch 165 for releasably engaging the other side rail 156 to further help to hold the support gate 155 in the closed position within the vehicle 152.
• the latch 165 is also releasable to permit the support gate 155 to swing open as described below.
• the top cross rail 159 includes two support brackets 167 as seen in Figure 37.
• the support brackets 167 are generally U-shaped to define an upward opening pocket sized to engage below the upper cross beam structure 32
• Figures 39 and 40 show the lift-transfer device 10 with its cross beam structure 32 aligned with and lowered downwardly into engagement with the support brackets 167.
• the lifting columns 30 and 31 are raised and lowered to first raise the cross beam structure 32 above the support brackets 167 and then lower the cross beam structure 32 into the engaged position of Figures 39 and 40. This engagement is performed when the trolley side rails 156 are extended out of the vehicle 152 as seen in Figures 35 and 39. Once engaged, the lifting columns 30 and 31 continue to be retracted, which then causes the wheeled base assembly 13 to lift from the ground as seen in Figure 41.
• the wheeled base assembly 13 is able to clear the vehicle bed 152A, which in turn allows the support gate 155 to be pushed into the cargo space 151 along with the lift transfer device 10 that is suspended therefrom as seen in Figure 42.
• This allows the lift transfer device 10 to be stowed within and later unloaded from the cargo space 151 by merely pulling or pushing to extend or retract the trolley side rails 156 and then raising or lowering the transporter base 13 using the powered lifting columns 30 and 31.
• the support gate 155 is in front of the lift transfer device 10 to block forward movement thereof within the cargo space 151.
• the lift transfer device 10 when the support gate 155 is opened as seen in Figure 43, the lift transfer device 10 also can be moved or rolled forwardly with the wheeled base 13 below the vehicle bed 152A and the patient support arms 68 and 69 above the bed 152A. As such, the lift transfer device 10 may be used to raise and lower articles into the vehicle bed 152A such as a wheelchair or the like. The articles may be suspended from the existing straps 118 and then disconnected therefrom once loaded in the cargo space 151. Thereafter, the support gate 155 may be closed and the lift transfer device 10 loaded in the vehicle 152 as described above.
