For example, a tab in the plurality of tabs 22 from FIG. 1 may contact the first roller when traveling in the longitudinal direction (e.g., −X-direction) and be guided laterally (e.g., in the +Y-direction) to the guide face 212 of the guide/restraint head 210, and then contact the second roller 216 and slide off the guide/restraint head 210. Then, in accordance with various embodiments, an adjacent tab in the plurality of tabs 22 from FIG. 1 may contact the first roller 214 and the process may continue. Thus, in accordance with various embodiments, the first roller 214 and the second roller 216 may be configured to reduce wear of the guide/restraint head 210 during loading of a cargo compartment, in accordance with various embodiments.


In various embodiments, the anti-rollout assembly 200, as disclosed herein, provides for a wider guide/restraint head 210. In this regard, the retracting and extending of the guide/restraint head 210 being along the lateral direction (e.g., +/−Y-direction), a width of the guide/restraint head 210 is no longer limited by a depth of the housing 240. In various embodiments, with brief reference to FIG. 2, by retracting and extending of the guide/restraint head 210 along the lateral direction, a single guide/restraint head may extend across an entire length or substantially an entire length of an entranceway 60, in accordance with various embodiments.


Referring now to FIG. 5A, a cross-sectional view of the anti-rollout assembly 200 in a raised state is illustrated, in accordance with various embodiments. In various embodiments, the anti-rollout assembly 200 is biased into a raised state. In this regard, the guide/restraint head 210 is pivotably coupled to the housing 240 via a torsion spring 250, or the like. In this regard, the torsion spring 250 is configured to bias the guide/restraint head 210 in an upward position, as illustrated in FIG. 5A.


In various embodiments, when the anti-rollout assembly 200 is in the raised position, the locking system 230 is configured to lock the guide/restraint head 210 in a vertical position. In this regard, the locking link 232 interfaces with a mating surface 218 of the guide/restraint head 210 in response to the anti-rollout assembly being in a raised state. In various embodiments, the locking link 232 would prevent a lateral force exerted on guide face 212 of the guide/restraint head 210 from a pallet (e.g., pallet 20 from FIG. 1) from causing the anti-rollout assembly 200 to retract. Thus, the locking system 230 is configured to ensure the guide/restraint head 210 remains raised to guide a pallet (e.g., pallet 20 from FIG. 1) after the pallet is on and within the entranceway 60 from FIG. 2, in accordance with various embodiments.


In various embodiments, the locking link 232 may comprise a tab 238 configured to interface with the pin 236 of the locking system 230, when the anti-rollout assembly is in the raised state. In various embodiments, the tab 238 and pin 236 interface may act as a redundant locking mechanism for the anti-rollout assembly 200, in accordance with various embodiments.


In various embodiments, the housing 240 defines a cavity 244 disposed therein. In various embodiments, the cavity 244 is configured to receive the guide/restraint head 210, the overridable trigger 220, and the locking system 230 therein. In this regard, in response to a pallet (e.g., pallet 20 from FIG. 1) rolling laterally into the overridable trigger 220, the overridable trigger 220, the locking system 230, and the guide/restraint head 210 are stowed in the cavity 244, as described further herein.


Referring now to FIGS. 5B-5D, a cross-sectional view of the anti-rollout assembly 200 along section A-A from FIG. 4 during retraction from a pallet (e.g., pallet 20 from FIG. 1) rolling over the anti-rollout assembly in a lateral direction (e.g., the +Y-direction) is illustrated in accordance with various embodiments. In various embodiments, in response to an initial force on the overridable trigger 220 in a lateral direction (e.g., Y-direction), the drive link 234 moves laterally toward the guide/restraint head 210, the pin 236 travels over the tab 238 of the locking link 232 driving the locking link downward away from the mating surface 218 of the guide/restraint head 210. In this regard, the pin 236 and the tab 238 interface may ensure that the locking link 232 does not maintain contact with the mating surface 218 of the guide/restraint head 210 when the guide/restraint head 210 is supposed to be retracting, as illustrated in FIG. 5B. In various embodiments, the pin 236 is configured to rotate about a longitudinal axis defined by the pin 236. In this regard, the pin 236 may rotate when traveling over the tab 238, which may prevent wear of the pin 236 and/or the tab 238 during use of the anti-rollout assembly, in accordance with various embodiments. Although the pin 236 is described as being configured to rotate, the pin 236 is not limited in this regard. For example, the pin 236 may be stationary and/or configured to slide, in accordance with various embodiments.


In various embodiments, as the force of the cargo (e.g., cargo 16 from FIG. 1) continues to drive the overridable trigger 220 in a clockwise direction, the drive link 234 drives the guide/restraint head 210 at coupling 235 about the torsion spring 250 in a direction opposite to the bias of the torsion spring 250, causing the guide/restraint head 210 to rotate counterclockwise into the cavity 244 of the housing 240 as illustrated in FIG. 5C. In various embodiments, the coupling 235 creates a moment arm measured from the torsion spring 250.


In various embodiments, the guide/restraint head 210 further comprises an aperture 211 disposed between the mating surface 218 and the coupling 235. In various embodiments, the aperture 211 may allow the locking link 232 an area to travel through during the retracting to prevent the locking link 232 from contacting the guide/restraint head 210.


In various embodiments, in response to a cargo being entirely or nearly entirely over the anti-rollout assembly, as illustrated in FIG. 5D, the guide/restraint head 210, the overridable trigger 220, and the locking system 230 are all stored in the housing 240, in accordance with various embodiments. In this regard, a downward force from the cargo (e.g., cargo 16 from FIG. 1), may maintain the anti-rollout assembly in the retracted state (e.g., FIG. 5D), until the cargo passes the overridable trigger 220, at which point the torsion spring 250 will begin to bias the anti-rollout assembly towards the raised state, causing the anti-rollout assembly to move from a FIG. 5D position to a FIG. 5C position to a FIG. 5B position, and back to a FIG. 5A position, in accordance with various embodiments.


Referring now to FIG. 6, a cross-sectional view of the anti-rollout assembly 200 from FIG. 4 is illustrated, in accordance with various embodiments. In various embodiments, drive link 234 is slidingly coupled to the guide/restraint head 210 at the coupling 235 of the locking system 230. In this regard, a pin 237 may be disposed through the guide/restraint head 210 and through a slot 239 in the drive link 234, causing the driving link to move a certain distance before driving the guide/restraint head 210 to rotate inward. Thus, in various embodiments, the slot 239 may ensure the locking link 232 is rotated out of the way of the mating surface 218 before driving the guide/restraint head 210 inward.


In various embodiments, the anti-rollout assembly 200 may further comprising a locking mechanism configured to lock the anti-rollout assembly 200 in a retracted state. For example, the anti-rollout assembly 200 may include a latch configured to extend over the overridable trigger to keep the anti-rollout assembly 200 in a retracted state for unloading the cargo handling system 50 from FIG. 2. In various embodiments, the locking mechanism may be any locking mechanism known in the art, such as a latch, a lock for the torsion spring, or the like.
