The disclosure will become more fully understood from the following detailed description, taken in conjunction with the accompanying figures, wherein like reference numerals refer to like elements, in which:
Before turning to the figures, which illustrate the exemplary embodiments in detail, it should be understood that the present application is not limited to the details or methodology set forth in the description or illustrated in the figures. It should also be understood that the terminology is for the purpose of description only and should not be regarded as limiting.
Referring to the FIGURES generally, the various exemplary embodiments disclosed herein relate to a litter lift system adapted for use within a vehicle, such as an ambulance or light tactical military vehicle, which can accommodate and transport several wounded or injured personnel away from an incident simultaneously. In other embodiments, the vehicle is an airplane, a tank, or still another system. In still other embodiments, the litter lift system is provided as part of a building or other non-vehicle system. The litter lift system generally includes a lifting strap that is coupled to a motor-driven winch system that can rotate to adjust a vertical position of two separate lifting segments of the lifting strap at an approximately even rate to suspend and balance a litter above the floor of a vehicle or surface (in the case of a non-vehicle use). Rotation of the winch system raises or lowers the lifting straps and litters suspended by the lifting straps to maintain the litter in an approximately parallel relationship with the floor of the vehicle below.
The winch system is coupled to or positioned near the roof or ceiling of the vehicle body. A portion of the lifting strap is routed above the ceiling and along (e.g., below) the roof of the vehicle body, outside the passenger compartment. Each lifting segment of the lifting strap is suspended downward, through passageways formed in the ceiling of the vehicle body, and into the passenger compartment where the lifting straps can be coupled to a NATO-style litter or other stretcher-type structure. When coupled to the lifting segments of the lifting strap, rotation of the winch system (in a first direction) raises and suspends the litter from the floor of the vehicle. By suspending the litter off of the floor of the vehicle body, the area of the vehicle below the suspended litter can be used to accommodate additional patients (e.g., on a second litter) or personnel. Otherwise unused vertical space within the vehicle body can be used by the patient suspended by the litter lift system. The vehicle can be outfitted with two identical litter lifting systems positioned on each side of the vehicle body to accommodate four or more litters within the same vehicle simultaneously, with two litters being suspended and two litters being positioned at or near the floor of the vehicle body.
The vehicle may be a military vehicle that includes a reconfigurable compartment. The reconfigurable compartment can include a floor, a front, a rear, a roof, and sides. The floor, the front, the rear, the roof, and the sides are removably coupled with each other to define the reconfigurable compartment. At least one of the floor, the front, the rear, the roof, or the sides are function-specific and replaceable with a different function-specific at least one of the floor, the front, the rear, the roof, or the sides to change an overall function of the military vehicle between a plurality of overall functions. The overall function of the military vehicle can be transitioned between a tactical military vehicle, an ambulance, a troop carrier, a communications vehicle, etc.
Referring now to
A vehicle body 18 is supported by the chassis 12. The vehicle body 18 includes both a cab 20 and a passenger compartment 22. The cab 20 can generally include vehicle control components, including a steering wheel (or joystick), gas and brake pedals, and a clutch system, for example. The cab 20 can also include seating to accommodate a vehicle driver and one or more passengers. In some autonomous versions of the vehicle 10, the steering wheel and control pedals are omitted from the cab 20. A hood 21 of the vehicle 10 extends forward from the cab 20 to house the prime mover (e.g., the motor 14) and various other vehicle subsystems (e.g., oil systems, HVAC systems, etc.)
The passenger compartment 22 is positioned behind the cab 20 on the vehicle chassis 12. The passenger compartment 22 is defined by a larger volume than the cab 20, and can be used to house various types of medical equipment, for example, to administer care to injured or wounded personnel at or while driving away from an incident location. Each of the cab 20 and passenger compartment 22 can be defined by an outer, armored steel plate construction. The cab 20 and the passenger compartment 22 can be joined together so that an internal passageway is formed between the cab 20 and the passenger compartment 22. Accordingly, personnel within the vehicle 10 can travel between the cab 20 and the passenger compartment 22 without exiting the vehicle 10.
With additional reference to
The passenger compartment 22 is designed to transport personnel and/or equipment. For example, seating can be provided within the interior of the passenger compartment 22 to help transport personnel within the passenger compartment 22. As shown in
Litter support systems 40 can be positioned along each sidewall 28, extending away from the rear wall 32 of the vehicle body 18. The litter support systems 40 can each rotate between a stowed position (shown in
With additional reference to
Litters 80 can be loaded onto the litter support system 40 through a rear loading mechanism 52, shown in
To load a litter 80 into the litter support system 40 within the passenger compartment 22, the litter 80 is lifted from the ground. The front legs 84 of a litter 80 can first be loaded into the channels 58, 60 of the rear loading mechanism 52 and then slid upward, at an acute angle to the floor 24 and channels 48, 50, until the rear legs 84 are also received within the channels 58, 60. The spacing between the channels 58, 60 of the rear loading mechanism 52 and the channels 48, 50 of the litter support system 40 is limited so that once the front legs 84 of a litter 80 pass upwardly and outwardly beyond the channels 58, 60, the litter 80 rotates toward a position parallel to the floor 24 of the passenger compartment 22. The rotation of the litter 80 toward the floor 24 rotates the front legs 84 of the litter 80 into the channels 48, 50 of the litter support system 40. The litter 80 can then be urged further forward until the rear legs 84 of the litter 80 are also received within the channels 48, 50 of the litter support system 40. With front and rear legs 84 within the channels 48, 50 of the litter support system 40, the litter 80 can be slid forward within the passenger compartment 22 until the litter 80 is received entirely within the passenger compartment 22. After a successful litter loading process is performed, the rear doors 54, 56 can be rotated upward and secured to the rear wall 32 of the passenger compartment 22.
Litters 80 received upon the frame 44 of the litter support system 40 can be elevated off the frame 44 so that additional litters and/or personnel can be secured within the passenger compartment 22 of the vehicle 10. As shown in
As depicted in
The lifting strap 104 is designed to receive, support, and lift a litter 80 away from the floor 24 (or channels 48, 50 of the base 46) of the vehicle body 18. With specific reference to
The front lifting segment 110 and the rear lifting segment 112 each include a forked structure that is designed to interface with the frame 82 of a litter 80. As depicted in
The lifting strap 104 extends forward from the first roller 122, above the ceiling panel 62 and approximately parallel to the floor 24 of the passenger compartment 22, to a second roller 124. The second roller 124, like the first roller 122, is mounted to the roof 26 of the passenger compartment 22. The second end and front lifting segment 110 of the lifting strap 104 wraps around the second roller 124 and is suspended downwardly, away from the front side of the second roller 124 and into the passenger compartment 22 of the vehicle 10. As depicted in
The lifting strap 104 and winch system 102 are arranged so that only a portion of the lifting strap 104 is exposed within the passenger compartment 22 of the vehicle 10. As depicted in
Using the litter lift system 100, a litter 80 and associated patient can be elevated (e.g., off of the litter support system 40, etc.), such that an additional litter 80 and patient can be accommodated upon the litter support system 40. The operation of the litter lifting system 100 is demonstrated by
With the front and rear lifting segments 110, 112 positioned in place around and coupled to the frame 82 of the litter 80, the litter 80 can be raised away from the litter support system 40. A user can then activate the winch system 102 and the electric motor 105 using a controller 132, shown in
The litter 80 and lifting strap 104 can be raised by the winch system 102 until a suitable height for the litter 80 is reached within the passenger compartment. Once a desired height is reached, support arms 134 can be positioned in place beneath the litter frame 82, as shown in
With the litter 80 positioned on the support arms 134 and raised away from the litter support structure 40 below, a second litter can then be received on the litter support structure 40, allowing the vehicle 10 to accommodate multiple litter patients simultaneously. With litter lifting systems 100 positioned on each side of the passenger compartment, up to four (or in some cases, more) litter patients can be received simultaneously within the vehicle 10 and transported away from an incident location. Upon arrival at a hospital or other facility, the litter 80 can once again be suspended and lowered down toward the litter support structure 40 using the lifting strap 104 and winch system 102, which unspools the lifting strap 104 and lowers the litter 80 in response to receiving a command from the controller 132.
When the litter lift system 100 is not in use and not needed, compact storage features can be used to further limit requirements of the litter lift system 100. In some examples, a coupling is positioned on each of the front and rear lifting segments 110, 112 to stow the suspended portions of the lifting strap 104 when not in use. For example, the coupling can be a metallic component 142 (e.g., iron) that is incorporated (e.g., sewn) into each of the first and second segments 114, 116 of the front and rear lifting segments 110, 112. The metallic component 142 can be adapted to releasably couple with opposing magnets 144 positioned on the ceiling panel 62 of the passenger compartment 22. By coupling the metallic components 142 with the opposing magnets 144, the lifting strap 104 can be confined to an area immediately adjacent to the ceiling panel 62, out of the way of passengers moving around within the passenger compartment 22. Alternatively, the couplings can be hooks or fastener panels (e.g., hook and loop fastener panels) that are attached to the front and rear lifting segments 110, 112 to releasably secure the front and rear lifting segments 110, 112 to the ceiling panel 62 when the litter lifting system 100 is not in use.

The reconfigurable compartment 1000 as shown in
The reconfigurable compartment 1000 can be transitionable into an ambulance compartment (e.g., the passenger compartment 22 including the litter lift system 100 as described in greater detail above with reference to
The reconfigurable compartment 1000 can be transitioned into a troop carrier compartment by removing one or more of the walls 1002 and replacing with troop carrier specific walls. For example, first side wall 1002c and the second side wall 1002e may be replaceable with troop-carrier specific first and second side walls that include or are configured to receive seating arrangement (e.g., benches, bucket seats, etc.) for troops (e.g., 6 or more troops).
The reconfigurable compartment 1000 can be transitioned into a communications vehicle compartment by removing and replacing one or more of the walls 1002 with communications specific walls that include or are configured to receive various communications equipment. In some embodiments, the front wall 1002b and the back wall 1002d, or the first side wall 1002c and the second side wall 1002e are removable and replaceable with walls that are function-specific for communications (e.g., that include or are configured to receive communications equipment).
Advantageously, the reconfigurable compartment 1000 can be transitioned into different functions by replacing one or more of the walls 1002 with function-specific walls that include or are configured to support various equipment, devices, etc., to transition an overall function of the reconfigurable compartment 1000 and thereby transition the vehicle 10 between different types of vehicles having different functions, overall purposes, different functional abilities, etc. A reconfigurable compartment 1000 facilitates transitioning an existing vehicle 10 into a different type of vehicle 10. For example, the vehicle 10 may be configured as an ambulance and, if a troop carrier is required, may be returned to a base or a hanger and transitioned into a troop carrier for transportation of troops. Advantageously, the reconfigurable compartment 1000 provides a versatile compartment that can be used to change the vehicle 10 between different types of vehicles for different mission purposes.
The reconfigurable compartment 1000 can be configured to fasten with the chassis 12 the same as or similar to the passenger compartment 22 as described in greater detail above with reference to
