Definitions
- This invention relates generally to vehicles, and more particularly, to a dislodging system for a vehicle.
- On-road and. in particular, off-road conditions can vary dramatically, particularly during inclement weather, such as rain.
- on-road and/or off-road conditions deteriorate, such as during rainy weather, vehicles may lose traction, sink into the ground surface, and become stuck. When this happens, the vehicles often can not dislodge themselves and need the assistance of another vehicle, such as a tow truck, to be pulled out. This process of getting a vehicle dislodged is time consuming and expensive.
- this device is not designed to dislodge a vehicle which is stuck in the ground. If the vehicle were operated on an unpaved surface and became stuck, the vehicle would likely sink far enough down that the hydraulic cylinders would also become stuck into the ground rendering them inoperable. Additionally, this device is quite complicated requiring multiple hydraulic cylinders to operate.
- the vehicle dislodging system in accordance with one embodiment of the present invention for a vehicle with a longitudinally extending vehicle frame includes a first arm and a drive system.
- the first arm has a first elongated section with opposing ends and a second elongated section with opposing ends.
- One of the ends of the first elongated section is pivotally connected to one of the ends of the second elongated section.
- the other end of the first elongated section is pivotally connected to the vehicle frame for rotational and longitudinal movement with respect to the vehicle frame.
- the drive system is connected to the vehicle frame and to the first arm and moves the first arm from a resting position adjacent the vehicle frame to an engaging position with the ground surface to move the vehicle longitudinally, either forward or to the rear.
- the vehicle dislodging system in accordance with another embodiment of the present invention for a vehicle with a longitudinally extending vehicle frame includes a support arm. a drive arm, and a drive system.
- the support arm comprises a first elongated section with opposing ends and a second elongated section with opposing ends.
- One of the ends of the first elongated section is pivotally connected to one of the ends of the second elongated section.
- the other end of the first elongated section is pivotally connected to the vehicle frame for rotational and longitudinal movement with respect to the vehicle frame.
- the drive arm has a pair of opposing ends with one of the ends of the drive arm being pivotally connected to the vehicle frame.
- the opposing end of the drive arm is pivotally connected adjacent to the other end of the second elongated section of the support arm.
- the drive system is connected to the vehicle frame and to the drive arm and rotates the drive arm and support arm from a resting position adjacent the vehicle frame to an engaging position with the ground surface to move the vehicle longitudinally, either forward or to the rear.
- the vehicle dislodging system in accordance with another embodiment of the present invention for a vehicle with a longitudinally extending vehicle frame includes a first power arm. a second power arm. a locking assembly, and a drive system.
- the first power arm has a pair of opposing ends with one of the ends being pivotally connected to the vehicle frame for rotational and longitudinal movement with respect to the vehicle frame.
- the second power arm has a pair of opposing ends with one of the ends of the second power arm pivotally connected to the other end of the first power arm.
- the locking assembly is connected adjacent the pivotally connected ends of the first and second elongated sections.
- the locking assembly has a first locked position holding the first and second power arms in an substantially straight position.
- the drive system is connected to the frame and to the first arm and moves the first arm from a resting position adjacent the vehicle frame to an engaging position with a ground surface to move the vehicle longitudinally, either forward or to the rear.
- One of the advantages of the vehicle dislodging system is that it provides an effective, convenient and safe way to dislodge a vehicle which has become stuck in the ground surface. With one or more reward or forward thrusts in a longitudinal direction, the vehicle can be lifted to a section of the ground, partially paved, or paved surface where the vehicle can resume normal driving operations. The time and expense of getting a separate vehicle to tow the stuck vehicle out is no longer needed. Additionally, the operator of the stuck vehicle can dislodge the vehicle without ever getting out of the safety and comfort of his or her own vehicle.
- vehicle dislodging system Another advantage of the vehicle dislodging system is with the convenience, reliability, and simplicity of its design.
- the assembly can be safely tucked away adjacent to the vehicle frame so that it does not interfere with normal operations or clearance for the vehicle.
- the driving system When the vehicle dislodging system is in use. the driving system is safely spaced above the ground and adjacent to the vehicle frame, so that when the ground engaging components sink into the wet ground surface the driving system is still spaced above the ground surface and is not damaged.
- the vehicle dislodging system has a much simpler design than prior vehicle shifting systems making it less expensive to manufacture and easier to install.

- the motor 38. drive shaft 34. sprockets 42 and 44, and roller chain 46 are safely spaced away from the surface S so that they will not be damaged or rendered inoperable.
- This movement of the drive arm 48 and support arm 16 in a counter-clockwise direction driving the extension 50 and shoe 58 into the ground results in the vehicle 12 being lifted up and off of the surface S and begins to longitudinally shift the vehicle 12 towards the rear R as shown in FIG. 3C and indicate by arrow Al .
- the vehicle 12 is lowered back down to the surface S as shown in FIG. 3D.
- the vehicle 12 has now been longitudinally shifted to the rear R and now may be able to resume normal driving operations.
- the vehicle 12 is shifted rearward about two-feet, although this distance can vary.
- the drive arm 48 and support arm 16 continue in a counter clockwise direction until the position shown in FIG. 3 A is reached again.
- the vehicle dislodging system 10(1) may continue to rotate the drive arm 48 and support arm 16 in a counter-clockwise direction through the process described above to longitudinally shift the vehicle 12 rearward until the vehicle 12 can resume normal driving operations.
- this longitudinally shifting operation to dislodge the stuck vehicle 12 is accomplished with relatively few parts. Additionally, the operator of the vehicle 12 never needs to get out of the vehicle 12 to dislodge the vehicle 12 if it gets stuck.
- the vehicle dislodging system 10(1) may also move the vehicle 12 forward F.
- the steps discussed above with reference to FIGS. 3A-3D are simply reversed and the drive shaft 34, drive arm 48, and support arm 16 are rotated in a clockwise direction, instead of a counter-clockwise direction, via the drive shaft 34, sprockets 42 and 44. roller chain 46, motor shaft 40, and motor 38.
- a vehicle dislodging system 10(2) in accordance with another embodiment of the present invention is illustrated.

- One end of each hydraulic cylinder 68 is pivotally connected to one of the longitudinally-extending sides 24(1) and 24(2) of the vehicle frame 14.
- control system 29 is located in the vehicle 12 and is used to control the operation of the pump 72 and motor 74. including controlling when the pump 72 is engaged or turned on to pump fluid into the hydraulic cylinders 68 to drive the hydraulic pistons 78 out, to pump fluid out of the hydraulic cylinders 68 to pull the hydraulic pistons 78 back in. or to be turned off.
- the parts and operation of hydraulic drive systems and control systems are well known to those of ordinary skill of the art. such as the ones disclosed in U.S. Patent No. 2,878,882 to Bemotas and in U.S. Patent No. 3.145.796 to Padula, which are herein incorporated by reference, and thus will not be described in detail here.
- the vehicle dislodging system 10(2) also includes the power arm 70 with a first elongated section 80 with a pair of opposing ends and a second elongated section 82 with a pair of opposing ends.
- one power arm 70 is located on each longitudinally-extending side 24(1) and 24(2) of the vehicle frame 14.
- the vehicle dislodging system 10(2) could have only one power arm 70 and associated component parts on each side 24(1) and 24(2) or more than two power arms 70 and associated component parts on each side 24(1) and 24(2) as needed or desired.
- first elongated section 80 is pivotally connected to the vehicle frame by a pin 84 or other pivoting device, such as a hinge or ball-and-socket joint, and the opposing end of the first elongated section 80 is pivotally connected by a pin 86 or other pivoting device, such as a hinge or ball-and-socket joint, to one end of the second elongated section 82.
- a spring 83 is connected to one end of elongated section 80 and extends down around both sides of a pin 85 adjacent one end of elongated section 82.
- the spring 83 which in this particular embodiment has a U-shape biases the elongated section 82 to a straight position with respect to the elongated section 80.
- the spring 83 may be located ⁇ n only one side of elongated sections 80 and 82 or may be located on both sides.
- the opposing end of the second elongated section 82 is connected to a replaceable shoe 58. such as that described earlier and illustrated in FIG. 2C.
- a replaceable shoe 58 such as that described earlier and illustrated in FIG. 2C.
- any type of spring or biasing means can be used which will bias the elongated section 82 to a straight position with respect to elongated section 80.
- the vehicle dislodging system 10(2) also includes a locking assembly 88 for each power arm 70 as illustrated in FIGS 4B and 4C.
- the locking assembly 88 includes a pair of locking mechanisms 88(1) and 88(2) which can be pivoted about pins 87(1) and 87(2) to lock the elongated section 82 with the respect to the elongated section 80 so that the elongated section 82 cannot pivot in a forward direction, a rearward direction, or in either direction.
- the locks 88(1) and 88(2) can be locked and unlocked either manually or automatically by a system (not shown). Although one particular type of locking assembly 88 is shown, other types of locking assemblies 88 can be used as needed or desired.
- the vehicle dislodging system 10(2) in accordance with another embodiment in a rearward thrust operation, i.e. to move the vehicle 12 in a rearward direction when stuck, is illustrated.
- the vehicle dislodging system 10(2) is in a parked or retracted position with the first and second elongated sections 80 and 82 of the power arm 70 biased to a straight position by spring 83.
- the locking assembly 88 locks sections 80 and 82 so that section 82 can pivot forward, but not rearward.
- the locking assembly 88 would lock section 82 with respect with to section 80 so that section 82 can pivot rearward, but not forward.
- the power arm 70 in the initial parked position the power arm 70 is tucked away adjacent the vehicle frame 14 so that it does not interfere with normal operation of the vehicle 12. does not cause it to lose clearance above the surface S and does not permit it to get damaged.
- the pump 72 When the vehicle 12 becomes stuck in or loses traction with the surface S, the pump 72 is engaged via the control system 29. To move the vehicle 12 towards the rear R. the pump 72 draws fluid out of the hydraulic cylinder 68 on each side 24(1) and 24(2) into the reservoir 66. As fluid is pulled out of the hydraulic cylinders 68. the hydraulic pistons 78 are pulled in to the hydraulic cylinders 66. This pulls the power arms 70 which are connected to the hydraulic pistons 78 forward longitudinally : %vith respect to the longitudinally-extending sides 24(1) and 24(2) of the vehicle frame 14.
- the hydraulic pistons 78 are connected to the first elongated section 80 of the power arm 70 so that the hydraulic cylinders 68 with pistons 78 remain close to the vehicle frame 14 and spaced from the surface S by at least the length of the extension of the second elongated section 82.
- the hydraulic cylinders 68 with pistons 78 will likely still be located above the surface S and be able to continue to operate.
- the hydraulic pistons 78 continue to pull the straightened power arms 70 which are engaging the surface S forward longitudinally. This causes the vehicle 12 to be lifted and shifted towards the rear R longitudinally in the direction indicated by arrow Al as shown in FIG. 5C.
- the control system 29 then signals the pump 72 to pump fluid in the reservoir 66 back into the hydraulic cylinders 68 which drives the hydraulic pistons 78 out and the power arms 70 rearward longitudinally.
- the first and second elongated sections 80 and 82 are pivoted back to the rear. If section 82 engages with the surface S during this retraction, the section 82 simply pivots forward about pin 86 as shown in FIG. 5E. When section 82 clears surface S, the spring 83 biases sections 80 and 82 back to a straight position.
- the above-described process is repeated until the vehicle 12 regains traction and can resume normal driving operations. Otherwise, the first and second elongated sections 80 and 82 on each side 24(1) and 24(2) may remain in the straight and parked position as shown in FIG. 5A until needed again. As illustrated and described, this longitudinally shifting operation to dislodge the stuck vehicle 12 is accomplished with relatively few parts. Additionally, the operator of the vehicle 12 never needs to get out of his vehicle 12 to dislodge the vehicle 12 if it gets stuck. As would be readily apparent to one of ordinary skill in the art. a forward thrust operation for the present invention would simply reverse the steps described above with respect to FIGS. 5A-5E and the direction in which locking assembly 88 locks the elongated sections 80 and 82.
