[0107] In the accompanying drawings, reference numerals may be used repeatedly to identify similar and / or identical elements. Detailed Implementation

[0108] This disclosure relates to portable and compact lifting systems that can be used to lift loads. In some examples, the lifting system is used to load and unload wheelchairs or other mobility devices from vehicles. In other examples, the lifting system can be used as a stand-alone system to lift other types of loads. For example, when a loading platform is unavailable, the lifting system can be used to load and unload objects from a towing trailer.

[0109] The lifting system includes a top plate, a bottom plate, a hinged plate connecting the top and bottom plates, and a bladder disposed between the top and bottom plates. In some examples used for loading and unloading wheelchairs or other mobility devices from a vehicle, the lifting system also includes brackets and / or track systems to extend and retract the lifting system from the vehicle's floor.

[0110] Now for reference Figure 1-4B This shows the lifting system 20. In Figure 1-4A In this system, the lifting system 20 includes a top plate 22, N pairs of hinged plates 24 and 26, and a bottom plate 28, where N is an integer greater than 2. Hinges 40 are used to connect plate 24 from each of the N pairs of hinged plates 24 and 26 to the top plate 22. In some examples, the hinges 40 connecting the plates 24 to the top plate 22 are arranged outwards adjacent to the outer surface of the top plate 22.

[0111] Hinges 40 are also used to connect the hinged plates 24 and 26 in each of the N pairs of plates 24 and 26 together. In some examples, hinges 40 connecting plates 24 and 26 are arranged inward on the inner edges of the pairs of plates 24 and 26.

[0112] Hinges 40 are used to connect plate 26 of each of the N pairs of hinged plates 24 and 26 to the base plate 28. In some examples, the hinges 40 for connecting plate 26 to the base plate 28 are arranged outwardly on the outer edges of the pairs of plates 24 and 26 adjacent to the outer surface of the base plate 28. When the bladder 50 is selectively inflated (or deflated) with fluid, the N pairs of hinged plates 24 and 26 maintain the parallelism of the top plate 22 and the base plate 28.

[0113] exist Figure 2 In the example shown, the top plate 22 is rectangular. The lifting system 20 includes four pairs of hinged plates 24 and 26 and three hinges for each pair of plates 24 and 26. More specifically, the multiple pairs of plates 24 and 26 include plates 24-1 and 26-1, 24-2 and 26-2, 24-3 and 26-3, and 24-4 and 26-4.

[0114] The longer side surface of one of the pairs of plates 24 and 26 and the shorter side surface of the other of the pairs of plates 24 and 26 are arranged along the respective sides of the lifting system 20. For example, the longer side surfaces of the pairs of plates 24-1 and 26-1 and the shorter side surfaces of the pairs of plates 24-2 and 26-2 are arranged along the side surface 53 of the top plate 22. Similar arrangements are made for the other side surfaces of the top plate 22.

[0115] The sac 50 is arranged in an internal cavity 51 defined between a pair of plates 24 and 26. Fluid (liquid or gas) is supplied to (or removed from) the sac 50 to inflate (or deflate) the sac 50, thereby raising (or lowering) the top plate 22 relative to the bottom plate 28.

[0116] exist Figure 4A In this system, the bladder 50 is partially inflated by fluid to raise the top plate 22 relative to the bottom plate 28. As the bladder 50 inflates, it expands against the top plate 22. As the bladder 50 expands or contracts, the angular positions of the paired plates 24 and 26 change. The paired plates 24 and 26 are hinged at one end, while the other end is connected to the top plate 22 and the bottom plate 28 via a hinge. When the lifting system 20 moves from a lowered position to an elevated position and then back to a lowered position, the paired plates 24 and 26 stabilize the top plate 22 under load and maintain parallelism between the top plate 22 and the bottom plate 28.

[0117] exist Figure 4B In this configuration, housing 52 may be arranged on the top surface of top plate 22 to accommodate one or more components, such as compressors, pumps, actuators, and / or power supplies.

[0118] Now for reference Figure 5 An example of a pneumatic system for a bag 50 is shown. A compressor 90 is connected to the bag 50 via a fluid conduit 91 and a valve 95. An actuator 92 is configured to power the compressor 90 with a power source 94 and / or control the valve 95. When energized, the compressor 90 supplies compressed air to fill the bag 50.

[0119] In some examples, valve 95 is a three-way valve, which includes a first valve state connecting the output of compressor 90 to fluid line 91, a second valve state connecting fluid line 91 to the atmosphere, and a third valve state blocking fluid line 91. When bladder 50 is inflated to raise the height of top plate 22, valve 95 is in the first valve state and compressor 90 is on. When top plate 22 is at a desired height or position, compressor 90 can be turned off and valve 95 enters the third valve state. When the height of top plate 22 needs to be lowered, valve 95 is moved to the second valve state to allow air to be released from bladder 50.

[0120] In some examples, actuator 92 includes a wireless receiver (not shown) actuated by a wireless transmitter (not shown). In some examples, a vehicle controller (not shown) controls actuator 92 wirelessly. In other examples, a wired connection is used to control actuator 92.

[0121] Now for reference Figure 6 The diagram illustrates a hydraulic system for the bladder 50. A pump 96 is connected to the bladder 50 via a fluid conduit 97. An actuator 92 is configured to power the pump 96 with a power supply 94. The actuator 92 causes the pump 96 to supply fluid to or remove fluid from the bladder 50 to adjust the height of the top plate 22.

[0122] Now for reference Figure 7-11 This shows that the lifting system 20 is installed on the surface or floor 114 of the vehicle 100. Figure 7 In this configuration, the lifting system 20 is arranged on the first and second brackets 124 and moves horizontally via the first and second track systems 120 (both arranged on opposite sides of the lifting system 20). The ramp 116 is rotatable about axis 118 and can be selectively deployed during loading and unloading.

[0123] exist Figure 8 In the diagram, the first and second track systems 120 are shown rotating in one direction to move the first and second track systems 120, the first and second brackets 124, and the lifting system 20 horizontally relative to the vehicle 100. In some examples, the first and second brackets 124 and the lifting system 20 move (relative to the vehicle) twice the displacement of the first and second track systems 120.

[0124] exist Figures 9 to 11 In the process, the bag 50 in the lifting system 20 is inflated and the bottom surface of the lifting system 20 moves towards the ground. When the bottom surface of the lifting system 20 is as... Figure 9 As shown, when in contact with the ground, ramp 116 is deployed to allow wheelchairs or other mobile devices to exit the vehicle.

[0125] The ramp 116 is raised and the bladder 50 is inflated to raise the top surface of the lifting system 20 above the first and second brackets 124. Figure 10 As shown, when the top surface of the lifting system 20 passes the first and second brackets 124, the first and second brackets 124 are retracted. Then, as... Figure 11 As shown, the lifting system 20 lowers the top surface to the ground, allowing wheelchairs or other mobility devices to be removed from the top plate 22. In some examples, an additional ramp (not shown) may be used to provide a gradient surface from the top plate 22 to the ground.

[0126] Now for reference Figure 12Examples of lifting system 20, first and second brackets 124, and first and second track systems 120 are shown. The first and second track systems 120 include annular belts 216 mounted on wheels 217 connected by horizontal members 218. In some examples, the first and second brackets 124 have a downward-facing "C"-shaped cross-section and an opening 214 configured to allow the first and second track systems 120 to pass through.

[0127] Now for reference Figure 13A and 13B This shows another example of orbital system 240. Figure 13A In this system, track system 240 includes an annular belt, such as chain 242, mounted on wheels such as sprockets 244. Sprockets 244 are rotatably connected by a horizontal member 246. One or more motors (not shown) drive one or both of the sprockets 244. The top plate 250 of the lifting system includes a bottom surface that includes teeth 252 that mesh with the chain 242. The floor surface 260 of the vehicle includes teeth 262 that mesh with the chain 242. Figure 13B In this process, the track system 240 moves the top plate 250 horizontally as described above.

[0128] Now for reference Figure 14-18 This illustrates another example of the lifting system 20. Figure 14 and Figure 15 In this configuration, the lifting system 20 rests directly on the first and second track systems 320, omitting the bracket. The first and second track systems 320 rotate in one direction to move both the first and second track systems 320 and the lifting system 20 horizontally relative to the vehicle. In some examples, the distance moved by the lifting system 20 (relative to the vehicle) is twice the displacement of the first and second track systems 320. Figure 15 In the vehicle, the first and second track systems 320 and the lifting system 20 are arranged on the floor 114 of the vehicle.

[0129] Ramp 116 was deployed ( Figure 16 Then the first and second track systems 320 rotate in one direction to move the first and second track systems 320 and the lifting system 20 horizontally relative to the vehicle, while the ramp 116 holds the lifting system 20 on the first and second track systems 320. Figure 17 As the lifting system 20 passes the vehicle, the bag 50 inflates and the base plate 28 moves toward the ground. When the lifting system 20 is on the ground, a wheelchair or other mobility device can disembark from the vehicle and onto the lifting system. The ramp is raised and the first and second track systems 320 retract. Figure 18 The lifting system 20 lowers the wheelchair or other mobility device to the ground.

[0130] Now for reference Figure 19-22This illustrates another example of the first and second orbital systems 410 used for lifting system 20. Figure 19 In the first and second track systems 410, wheels 412, a horizontal member 424 extending between the wheels 412, and an annular belt or chain 420 arranged around the wheels 412. The lifting system 20 includes a link 436 pivotally mounted about an axis 438 on its side surface. Although one link is shown on each side, two or more links may be used on each side. The horizontal member 424 of the first and second track systems 410 includes a channel 440 configured to removably receive the link 436. The channel 440 includes an upper opening 442 wider than the width of the link 436. The channel 440 is longer than the length of the link 436.

[0131] Upgrade System 20 Figure 19 The image is shown in an elevated position corresponding to the higher pressure in the bladder 50, and the first and second track systems 410 are extended. As the pressure in the bladder 50 in the lifting system 20 decreases, the top surface of the lifting system 10 moves downward and the connecting rod 436 enters the upper opening 442 of the channel 440 in the vertical direction, as shown. Figure 20 As shown. As the top surface moves further downwards, as... Figure 21 and 22 As shown, the end of link 436 rotates and moves horizontally into channel 440. This operation is reversed when lifting system 20 is removed.

[0132] Once the linkage 436 is as follows Figure 22 As shown in the diagram, link 436 prevents rotational movement of the lifting system 20 when it is not in contact with the ground. Therefore, link 436 prevents the lifting system 20 from tipping over from the first and second track systems 410. Mechanical disturbances to link 436 (when they are vertically loaded) cannot accommodate the arc-shaped travel path created by tipping. When the lifting system moves vertically, as the bladder reaches full inflation, the top surface of the lifting system extends above the first and second track systems 410, and link 436 moves outside the channel 440.
