Definitions
- the upper belt may be maintained stationary with respect to the rotating lower belt.
- the belts may be actuated either automatically or manually.
- a patient is moved by placing the device adjacent to him.
- the transfer device is moved toward the patient.
- the leading edge of the upper belt is positioned slightly forward of that of the lower belt.
- the transfer device may form an integral part of a wheeled stretcher, or it may be used independently. Upon arrival the patient is off-loaded by rotating the leading edge of the upper belt in a downwardlyoriented direction.
- This invention pertains to a method and apparatus for moving objects to a desired location. While the method and apparatus of the present invention will be discussed with respect to transporting a non-ambulatory patient to various hospital locations, it is to be understood that the invention is equally applicable to the moving of any appropriate object, such as a box or crate, from one place to another.
- the present invention embodies a method and apparatus which effectively solves every aspect of the patient transfer problem.
- this innovation employs a pair of endless belts, one of which is positioned above the other, rather than using only a single belt and/or a single set of rollers.
- the invention does not have to be wedged under the patient in order to lift him, as is the case in the prior attempts to solve the problem.
- the patient is gently and uniformly lifted up and onto the transfer device by the cooperating interaction of the superposed belts.
- the overall height of the superposed belts is only approximately 2 inches.
- the leading edge of the upper belt gently and uniformly lifts the patient up and onto the transfer device.
- the upper belt leading edge is located slightly forward of the leading edge of the lower belt. Since the upper belt leading edge is turning in an upwardly-oriented direction, the resulting lifting action consists of a cooperating contact movement which in no way wedges or pinches the patient. It is uniformly conveying the patient up and onto the upper surface of the transfer device, rather than initially wedging or pushing him down and away from it, as do the earlier devices.
- the basic concept of the invention may be effectively utilized whether the belts are automatically or manually actuated.
- the device may be employed either as an independent unit, or as an integral automaticallyactuated portion of a wheeled stretcher.
- the invention may be used to move heavy objects such as crates or boxes.
- the basic concept is equally applicable; the dimensions of the device could be varied if desired, and the structure could be strengthened if necessary to support extremely heavy objects.
- the apparatus is moved into a position parallel to the patient on the bed.
- the transfer device forms an integral part of a wheeled stretcher unit.
- the overall height of the unit may be adjusted and the transfer device can be moved outwardly from the stretcher along telescoping guides or rails.
- the transfer apparatus or device is actuated by a pair of electric motors through appropriate control switches.
- the transfer device itself includes two superposed sheets of a material having a low co-eflicient of friction (such as aluminum or plastic), each of which has a rounded leading edge. Each sheet is surrounded by an endless belt which readily rotates or slides around the sheet.
- the endless belts are in frictional contact with each other.
- Each of the endless belts is looped around a roller, the rollers being positioned superadjacent to one another at the trailing edge of the sheets.
- Each belt is in frictional contact with a second driving roller, the driving rollers being located adjacent to the respective driven rollers.
- Each of the driving rollers is driven by a separate electric motor. When the driving rollers are actuated, the upper rear roller drives the upper forward roller and the lower rear drives the lower forward roller by means of frictional contact therebetween.
- the stretcher is actuated by the electric motors through a drive pinion which is connected to the lower driving roller by a shaft.
- the pinion moves along a rack, thus extending the transfer device outwardly on telescoping guide rails.
- the motor for the lower roller set is reversed, while the motor for the upper set is deactivated.
- the transfer device is retracted or returns to the wheeled stretcher along the guide rails, the lower belt rotates while the upper belt remains stationary.
- a braking action occurs in the top belt because of the friction of the upper belt plus the resistance required to turn the gear reduction motor backward through the planetary reduction gearing.
- an electric brake could also be used to keep the upper belt stationary during retraction.
- the lower pair of rollers could be coupled together and driven by suitable gearing; the upper roller set could be similarly arranged.
- a slight modification of this embodiment could be effected by replacing each of the sheets with a plurality of spaced longitudinally-oriented rollers which would be journalled in an appropriate frame.
- one of the rollers in each belt could be connected by a shaft to a driving pinion.
- the pinion would be driven by an electric motor located within the housing of the wheeled stretcher. The actuation of operation of this modification would be substantially identical to that which has been previously described.
- the overall height of the superposed belts is only approximately 2 inches so that the transfer device may readily roll beneath and lift the patient on to the stretcher.
- the length of the device is approximately six feet and the width is about 24 inches. Of course, these dimensions can be varied without departing from the basic concept of the invention.
- a frame can be positioned transversely of the device at approximately the longitudinal midpoint thereof.
- the transfer device again forms an integral part of a rolling or wheeled stretcher.
- the transfer device is actuated by means of a hydraulic cylinder which acts in concert with a chainsprocket system to extend and retract the device.
- each of the superposed endless conveyor belts surrounds a plurality of longitudinally oriented rollers.
- the upper roller-belt arrangement may assume either a raised cradle transfer position, or a lowered loading/offloading position.
- each of the outer upper rollers is pivoted downwardly by suitable means such as a single-acting hydraulic cylinder which forces the rollers down, overcoming an opposing spring, thereby tightening the upper belt and forcing it into frictional engagement with the lower belt.
- suitable means such as a single-acting hydraulic cylinder which forces the rollers down, overcoming an opposing spring, thereby tightening the upper belt and forcing it into frictional engagement with the lower belt.
- the device is caused to roll toward and under the patient, and the patient is gently lifted up and onto the upper belt.
- the cylinder is deactivated and the downwardly directed force on the outer upper rollers ceases.
- rollers then reassume their normal position, which forms a protective cradle or pocket of U or V- shaped, cross-section when viewed from either end of the device. Since the upper belt is slack, the rotational movement of the lower driving belt imparts no movement to the upper belt, which remains stationary during retraction of the transfer device. This embodiment alfords an added measure of protection to the patient while he is being transported from one location to another.
- the transfer apparatus was integrated with a wheeled or rolling stretcher.
- the transfer device would normally be placed on a separate rolling stretcher and wheeled to a desired location such as an X-ray technicians room.
- the following embodiments are adapted to be actuated manually rather than mechanically or electrical- 1y.
- the transfer device consists of a pair of superposed endless conveyor belts, each of which surrounds a respective roller set.
- Each roller set comprises a plurality of spaced longitudinally-oriented rollers.
- the belts are capable of being brought into frictional contact with one another. When they are in frictional contact, the rotational movement of the lower belt imparts a reverse rotational movement to the upper belt. Thus when the latter contacts the patient it once again gently and uniformly lifts the patient up and onto the transfer device.
- the frictional contact force between the upper and lower belts should provide sutficient lifting force to gently ease an adult of average weight onto the upper belt.
- both the upper and lower horizontal roller sets are mounted in a common main frame.
- Each of the rollers is journalled in the main frame by means of appropriate bearings.
- the trailing upper roller is connected to a pivot bar which is hinged to the main frame in such a manner that it may be pivoted about the main frame.
- the superposed belts and associated roller sets are normally not in frictional driving contact with one another.
- the pivot bar is rotated through a rearwardly-directioned arc. This pivoting action tightens the endless belts against one another, thereby providing sufficient frictional contact to allow the patient to be gently lifted up and onto the device.
- the pivot bar is allowed to return to its normal (belts not in contact) positon, and the device may be rolled wherever desired without the risk of having the patient fall from the device.
- a pair of superposed endless conveyor belts are again employed.
- Each of the endless belts surrounds a roller set.
- Each of the lower rollers is journalled in a movable frame and is linked to a corresponding upper roller which is mounted in a stationary frame.
- the upper belt is locked against further movement by a suitable brake which prevents each of the upper rollers from rotating.
- the brake is released and the patient is off-loaded in the normal manner.
- the basic concept of the invention resides in the provision of a pair of superposed endless belts in which the leading edge of the upper belt is turning in an upwardly-oriented direction as it approaches and contacts the patient so that it lifts him smoothly and surely up and onto the transfer device in an expeditious effective manner.
- the conditon of the patient is not further aggravated by being lifted by hospital personnel, nor will his body be pinched as the belt comes into contact therewith, as would appear to be the case with prior attempts to solve the problem.
- the present invention keeps him there during transport by ensuring that the upper belt remains motionless during this period.
- the transfer device can be integrated with a wheeled stretcher further enhances the utility and effectiveness of the invention, since there is no'possibility of an attendant accidentally applying too much force as he attempts to roll the patient up and onto the transfer device. Additionally, since each of the previously described embodiments can be operated by an unassisted nurse, the invention assists in the alleviation of the manpower problem which plagues most hospitals today.

- FIGURES 1 and 2 of the drawings a preferred embodiment of the invention is depicted.
- a wheeled stretcher is combined or integrated with a patient transfer device which is generally indicated 22.
- the wheeled stretcher 20 is conventional in design and serves as a mobile platform for the invention.
- the patient transfer device 22 comprises a pair of rectangular endless conveyor belts 24 and 26 positioned one above the other.
- the endless belts themselves may consist of a rubber or canvas material which possesses suflicient gripping or adherence characteristics to convey an adult patient up and onto the transfer device without slipping or sliding occurring.
- the overall dimensions of the belts may be approximately 6 feet in length and 2 feet in width and may be varied if desired.
- Each of the endless belts covers or surrounds a plurality of spaced parallel, longitudinally oriented metal rollers which are generally designated 28 in the drawings. These rollers are of conventional structure and are journalled in a common U-shaped metal frame 30 by means of appropriate bearings.
- rollers could be replaced by a pair of superposed metal or plastic sheets which are shown in FIGURES 3 and 4 of the drawings. This variation will be discussed more fully hereinafter.
- the transfer device 22 may be extended and retracted laterally from the wheeled stretcher 20.
- the transfer device will travel outwardly along a pair of conventional guide rails, one of which is located at each end of the transfer device (not shown in the drawings).
- Lower endless conveyor belt 26 is adapted to rotate by connecting the rear roller in the lower roller set to a pinion gear 34. This is achieved by the provision of a shaft 44.
- Pinion 34 in turn moves along a rack 32 which is mounted at one end of wheeled stretcher 20.
- a chain member 36 is linked to the pinion 34 and is also connected to a driving motor 52 which is positioned within the wheeled stretcher itself. Spacing of the chain is assured by spacer pinions 38 and associated bracing members 40.
- the motor 52 drives lower belt 26 through a shaft on which pinion 42 is mounted. Pinion 42 powers chain 36 thus moving pinion 34 back and forth along rack 32.
- Upper belt 24 is driven by a system which is identical to that which drives lower belt 26, except that the pro vision of a rack is eliminated, and a conventional slip clutch (not shown in the drawings) is included in the drive system.
- a motor 52, pinion 42, chain 36, spacer pinions 38 and braces 40, and pinion gear or sprocket 34 are likewise mounted at the opposite end of the stretcher '20, and pinion 34 drives the rear roller of the upper roller set in order to rotate upper belt 24.
- upper belt 24 is rotated in a direction which is opposite to that of lower belt 26.
- FIGURE 2 of the drawings a detailed view of the upper portion of the driving mechanism is disclosed.
- two independent driving systems are employed.
- Each of the belts are driven through a conventional gear reduction system.
- Shaft 44 ex- 8 tends through longitudinal slot 46, thus enabling lower belt 26 to be extended and retracted on the guide rails.
- stretcher 20 is moved to a position adjacent the bed.
- the stretcher 20 and transfer device 22 may be vertically adjusted by a conventional mechanical crank 54.
- the height of the stretcher could also be adjusted by the provision of double-acting hydraulic cylinders, or if desired, by the employment of any conventional means which is normally used to raise and lower a wheeled stretcher.
- Each side of wheeled stretcher 20 would be provided with a cover or housing member 50 which would shield the drive mechanism from view.
- the transfer device is actuated by energizing an electric switch on control box 18 which starts the motors 52.
- the motors impart a rotational movement through appropriate reduction gearing to the pinion 42.
- Pinion 42 causes chain 36 to rotate around spacer pinions 38, thus causing pinion 34 to move outwardly in the direction of the arrow along rack 32.
- FIGURE 1 shows the transfer device 22 in a fully extended position. Since the other end of the wheeled stretcher contains a virtually identical drive system, a simultaneous driving action occurs, except that upper belt 24 is driven, rather than lower belt 26, and the rack is eliminated as described above.
- the upper leading edge is constructed so that it is directed downwardly toward the surface on which the patient is reclining; that is, it droops slightly.
- the telescoping guide rails move along with it.
- the guide rails provide support for the transfer device, as well as ensuring that it extends in a uniform manner.
- the leading edge 56 of the upper belt contacts the patient along the length of one side of his body as he reclines on bed 48.
- the upwardly oriented rotation of the upper belt gently and uniformly lifts or conveys the patient up and onto the upper belt 24.
- the lower belt 26 has, of course, been rotatably traveling along the bed sheet in frictional contact therewith and is also assisting in imparting reverse rotation to upper belt 24 due to the frictional contact between the belts.
- the transfer device 22 After the transfer device 22 has been fully retracted, the patient is moved to a desired location simply by wheeling the stretcher 20 in the normal manner. When it is desired to off-load the patient, the procedure is exactly the reverse of that which has been described in detail above. Thus, when the transfer device 22 is being extended, the leading edge 56 of the upper belt is rotating in a downwardly-oriented direction, and the patient is gently and uniformly off-loaded at the desired location.
- a transfer device 22 in which the basic concept employed is identical to that of FIGURES 1 and 2.
- the electric motors are housed in an integral housing member 58 which extends and retracts together with the endless belts.
- sheet members 60 and 62 are utilized instead of a plurality of spaced longitudinally-oriented rollers. It is apparent that the sheets and rollers are readily interchangeable with each other since they both perform the same basic function. They act as support means or members for the upper and lower belts respectively, enabling the belts to readily rotate around them.
- the sheet members possess surfaces which have a low co-efiicient of friction and are relatively slippery so that the upper and lower belts may readily slide over them.
- the switches on control box 64 are used to energize a pair of electric motors 66 and 68.
- Motors 66 and 68 drive rollers 70 and 72 respectively, through appropriate gear-reduction mechanisms which are not shown in the drawings.
- Rollers 70 and 71 are in frictional driving contact with upper belt 24 and lower belt 26 respectively.
- Upper belt 24 extends or is looped around a roller 74, and lower belt 26 extends around a similar roller 76.
- a shaft 78 extends outwardly from roller 72 to pinion gear 80, which in turn moves back and forth on rack 82.
- leading edge 56 is positioned slightly forwardly of the corresponding leading edge of lower belt 26, and is directed or inclined downwardly toward the surface on which the patient is reclining. This is accomplished by forming upper sheet 62 with a downwardly inclined, overhanging leading edge which may be termed a droop snout. As before, this construction is provided in order to facilitate the lifting and loading of the patient, as well as ensuring that the downwardly-oriented rotation of the leading edge of lower belt 26 does not contact the patient.
- roller 72 imparts a rotary movement to pinion 80 through shaft 78.
- Pinion 80 moves outwardly along rack 82, thus causing the entire transfer device 22 to extend outwardly along a pair of guide rails in the manner which has been described previously.
- FIGURES 5 and 6 of the drawings another embodiment of the basic concept of the invention is disclosed.
- the transfer device forms an integral part of conventional Wheeled stretcher 20, and is capable of vertical adjustment in the manner which has been previously described.
- the extension and retraction of the transfer device is accomplished by a hydraulic system.
- a double-acting hydraulic cylinder 86 is secured to the wheeled stretcher 20 by a brace of bracket 88. The rod end of the cylinder is secured to frame 100.
- Lower forward roller 108 (see FIGURE 6) is connected to forward sprocket 92 by a suitable stub shaft (not shown).
- rear lower roller is connected to rear sprocket 94 by a second stub shaft. Both of these stub shafts pass through openings in frame 100.
- a chain 96 is looped around the sprockets and is fixed to the Wheeled stretcher 20 by a bolt or the like at 98.
- FIGURE 6 of the drawings is a detailed view of the transfer device employed in this embodiment of the invention.
- the transfer device which is generally indicated at 102 in the drawings, consists of a pair of belts positioned one above the other.
- the lower or drive belt 104 comprises an endless conveyor belt which is wrapped around a plurality of spaced longitudinally-oriented rollers 106, 108 and 110.
- stub shafts connect the forward lower rollers 108 and 110 to sprockets 92 and 94 respectively. Accordingly, as the sprockets 92 and 94 rotate, they impart rotational movement to the lower roller set, which in turn causes lower belt 104 to rotate as it rolls along the surface such as a patients bed.
- the lower or driving belt 104 is tightly fitted around the lower roller set in order to maintain a taut configuration.
- the upper belt or cradle belt 112 is normally in a slack configuration. When it is in this slack configuration it resembles a cradle or pocket since it is U-shaped or crescent-shaped when viewed from either end of the transfer device.
- the lower driving belt 104 cannot impart any rotational movement to the upper belt due to the lack of effective frictional contact between them.
- Upper belt 112 is wrapped around a group of at least 4 spaced, longitudinally-oriented rollers 114, 116, 118 and 120.
- the outer rollers 114 and 120 are pivotally attached to the inner rollers by means of links 122 and 124 respectively, and thus are capable of movement through a limited vertical arc.
- the cradle belt 112 When it is desired to transport a patient who is reclining on the retracted transfer device 102, the cradle belt 112 is in the position shown in FIGURE 6. When it is desired to load or off-load a patient, upper belt 112 as sumes the position which is partially shown by the broken or phantom lines in FIGURE 6. This is accomplished by means of a pair of single-acting hydraulic cylinders 126. When hydraulic fluid is introduced through hose 130, piston 132 overcomes spring 134 and causes the outer rollers to pivot downwardly, thus tightening the belt 112.
- the stretcher 20 is wheeled to a position adjacent the bed and hydraulic actuating fluid is introduced through hose 136. This extends cylinder rod 138, moving frame 100 outwardly and causing sprockets 92 and 94 to rotate, which in turn drives the lower belt 104 through rollers 108 and 110.
- hydraulic cylinders 126 are deactuated and springs 134 cause the upper belt to reassume the cradle position by returning rollers 114 and 120 to their normal position.
- fluid is removed from the piston end of hydraulic cylinder 86 and hydraulic fluid is introduced through hose 142 to the rod end of cylinder 86.
- This causes the cylinder rod 138 to retract, which in turn reverses the rotation of sprockets 92 and 94 causing drive belt 104 to turn in a counterclockwise direction as it returns to wheeled stretcher 20.
- cradle belt 112 remains stationary due to lack of frictional driving contact with the lower belt 104.
- the shape or configuration of the cradle belt assures an added measure of safety to the patient in preventing his falling from the trans-fer device While being moved to a desired location.
- the transfer device was integrated with a wheeled or rolling stretcher.
- the transfer device comprises a separate element, which after loading the patient thereon, would normally be placed on a separate rolling stretcher and Wheeled to a desired location such as an X-ray technicians room.
- the following embodiments are adapted to be actuated manually rather than by powered means.
- FIGURE 7 is a top plan view of a transfer device 150.
- Transfer device 150 includes a common frame 152, in which are journalled a plurality of rollers 154, 156, 158, 160, 162 and 164. Rollers 154 and 164 form the upper rollers of the transfer device, and an upper endless conveyor belt 166 is Wrapped around the upper rollers. Simi larly, a lower endless belt 168 is positioned around the lower roller set.
- the endless belts used in all of the embodiments of the invention may be comprised of the same material, i.e. rubber, canvas or the like.
- a rectangular metal plate 170 is secured to the frame and is substan tially coextensive with the upper and lower belts.
- plate 170 provides additional support for an object which is to be placed on the transfer device 150.
- a pivot bar 172 is secured to the common frame 152, as well as to the rear upper roller 164. As is seen from FIGURE 7 of the drawings, the pivot bar extends from one side of the belts to the other, and is oriented in the same direction as rollers 154-164. The pivot bar can be manually moved in the direction of the arrow in FIGURE 8.
- Upper belt 166 is normally in a slack position which is similar to that of upper belt 112 in FIGURES and 6. Therefore, when the lower belt 168 is actuated by rolling it along a surface such as a patients bed, it cannot impart a reverse rotational movement to upper belt 166 due to a lack of frictional driving contact between the belts.
- pivot bar 172 is rotated in a 12 clockwise direction, i.e., in the direction of the arrow in FIGURE 8. This movement causes the upper belt 166 to tighten, thus achieving an effective frictional contact with lower belt 168.
- the pivot bar 172 is again rotated rearwardly, the belts are once again in taut frictional contact and the patient is smoothly and efiiciently off-loaded from the device.
- FIGURES 9 and 10 of the drawings depict a side view of a plurality of spaced, longitudinally-oriented rollers.
- the rollers are mounted in separate upper and lower frames designated 184 and 186 respectively.
- a pair of endless conveyor belts are wrapped around the upper and lower roller sets.
- upper belt 188 is superposed or positioned above lower belt 190.
- Each of the adjacent upper and lower rollers are linked to one another by a series of links indicated at 192 in the drawings.
- FIGURE 9 shows the position of the upper and lower belts when a patient is being transported on the transfer device 180.
- the belts are not in frictional contact with one another because of the presence of brake 194.
- Brake 194 is mounted on lower frame 186 by means of suitable bolts and comprises an angle member 200 with a rubber nub or ball 196 which is in frictional contact with the upper roller in any given linked roller pair.
- a brake member 194 is provided for each linked roller pair. The brake is locked in this position by a suitable cam (not shown) when a patient is being transported on the transfer device.
- the transfer device 180 When it is desired to load (or off-load) a patient, the transfer device 180 assumes the position shown in FIG- URE 10 of the drawings.
- the brakes 194 are unlocked, and when the transfer device 180 is manually actuated by a suitable push-pull bar (not shown in the drawings) the lower belt begins to rotatably move along a surface such as a patients bed.
- the lower frame 184 on which it is mounted pivots rearwa'rdly with respect to the stationary upper frame 186. Accordingly, the upper and lower belts are brought into frictional driving contact with one another so that the lower belt imparts a reverse rotational movement to the upper belt 188 and vice-versa.
- the present invention keeps him there during transport by ensuring that the upper belt remains motionless during this period.
- the fact that the transfer device can be integrated with a wheeled stretcher further enhances the utility and effectiveness of the invention, since there is no possibility of an attendant accidentally applying too much force as he attempts to roll the patient up and onto the transfer device.
- the invention assists in the alleviation of the manpower problem which plagues most hospitals today.
- a method of moving an object onto a frame means having a horizontal upper surface through a transfer device carried by said frame means comprising the steps of:
- said transfer device having a lower endless belt with a support means enclosed therein and a superposed upper endless belt with a support means enclosed therein whereby due to the superposed belts and support means the weight of the object is transferred through the belts and the support means of said transfer device to the area of said surfaces directly beneath the object during operation of said transfer device, and means for rotating said belts relative to their respective support means, rotating said lower endless belt relative to the support means of said lower endless belt to effect movement of said transfer device along said surface,
- said power means comprise at least two electric motors including a first motor adapted to drive said lower belt and a second motor adapted to drive said upper belt.
