• a handle end portion, formed of a beam, extends generally perpendicularly between the two spaced apart and parallel lateral side portions at proximate ends thereof and is structurally interconnected thereto at adjacent end portions, and the handle end portion carries an upwardly extending handle, and
• a foot end portion formed of a beam, extends between and is structurally interconnected to proximate end portions of the two spaced apart and parallel lateral side portions, opposite the handle end portion, and the foot end portion is not parallel to the handle end portion, and
• strengthening braces are spacedly arrayed between, and structurally interconnect the spaced apart parallel lateral side portions, and
• aplurality of wheel brackets carried on an underside of each parallel lateral side portion, and each of the plurality of wheel brackets support at least one roller wheel on an axle, so that at least one roller wheel rolls along an upper surface of the parallel lateral side portions of the fixed height frame upper frame member, and
• a generally planar and elongate roller shield is carried by, and depends downwardly from, an underside of the slidably movable bed deck frame adjacent laterally outwardly of the wheel brackets, on each lateral side portion of the slidably movable bed deck frame, each roller shield having a height dimension that is greater than a diameter of the ate least one roller wheel, and having a length dimension that is greater than the distance between the plural wheel brackets carried on one lateral side portion of the slidably movable bed deck frame, so as to simultaneously shield the roller wheels of the spaced apart wheel brackets from entanglement, and
• a latch assembly, with an operator handle, on an underside of the slidably movable bed deck frame to releasably engage with the spaced apart and upwardly oriented teeth of the adjustment rack carried by the fixed height frame, and
• a generally planar load supporting deck, having a top load supporting surface and an opposing bottom surface, is carried by the slidably movable bed deck frame between the opposing end portions and between the parallel and spaced apart lateral side portions, and
• a puck receiver is defined in the generally planar load supporting deck generally medially between the opposing parallel and spaced apart lateral side portions and spacedly adjacent the second handle end portion to releasably engage with an outwardly extending puck of the stretcher, the puck receiver having a first angled engagement guide, a second angled engagement guide, a puck anchor head and a puck lock;
• the first and second angled engagement guides defining receiver opening opposite the anchor head to guide the “puck” carried on the underside of the stretcher into engagement with the puck lock proximate the puck anchor head;
• and
• an elongate side rail carried by the slidably movable bed deck frame on plural spacedly arrayed side rail mounting posts adjacent each opposing lateral side portion of the slidably movable bed deck frame and extending parallel to, and spacedly above, the top load supporting surface of the generally planar load supporting deck, each elongate side rail having a first end portion, a spaced apart second end portion, and a side rail rotation frame between the first end portion and the second end portion, the side rail rotation frame structurally carrying a generally planar, and pivotally movable slide rail panel that has a top surface, an opposing bottom surface, a hinge edge and a distal edge, and the slide rail panel is movable between a first locking position wherein the slide rail panel is oriented generally vertically, and generally perpendicular relative to the top load supporting surface of the generally planar load supporting deck providing a physical barrier to retain a patient on the top load supporting surface, and a second position wherein the slide rail panel is oriented generally coplanar with, and spaced Laterally adjacent to, the top load supporting surface of the load supporting deck to facilitate movement of the stretcher and patient thereon onto and off of the top load supporting surface.

A transfer assist device for transferring a stretcher carrying a patient from a wheeled gurney to a first location, and from the first location to a wheeled gurney, or to a second location, the transfer assist device comprising:

• a fixed height frame having a first end portion, a second end portion, a first lateral side, a second lateral side and a predetermined height dimension between an upper edge portion and a lower edge portion;
• an adjustment rack, adjacent the upper edge portion of the fixed height frame, that provides controllable movement, and positional securement, of a slidably movable bed deck frame relative to the fixed height frame between a first position wherein the slidably movable bed deck frame is positioned adjacent above, and substantially centered over, the fixed height frame, and a second extended position wherein the slidably movable bed deck frame is translated along the fixed height frame to extend endwardly outwardly from a first end portion of the fixed height frame;
• the slidably movable bed deck frame is rectangular in peripheral configuration and has a handle end, a foot end, a first lateral side and a second lateral side and the first and second lateral sides are parallel to one another, and are both longer in length dimension than the handle end and the foot end, and the foot end is parallel to the handle end;
• a plurality of slide brackets structurally carried on an underside of the slidably movable bed deck frame, and each of the plurality of slide brackets support at least one slide member that translates along the upper edge portion of the fixed height frame so that the slidably movable bed deck frame translates along the fixed height frame;

• a generally planar load supporting deck carried by the slidably movable bed deck frame between the handle end and the foot end and between the parallel lateral side portions;
• and
• a puck receiver is defined in the generally planar load supporting deck between the lateral side portions and spacedly adjacent the handle end portion to releasably engage with an outwardly extending puck carried by the stretcher.
