1. Field of the Invention
The invention generally relates to the field of personal load bearing equipment. More specifically, the invention relates to rapidly detachable load carriage connectors and systems.
2. Description of the Related Art
Soldiers, especially members of agile and rapidly deployable units, civilians engaged in activities such as hiking, and public safety personnel such as persons engaged search and rescue missions all require reliable systems for the effective carriage of necessary equipment. The most simplistic backpacks and rucksacks (“packs”) often do not incorporate a frame or other rigid load distribution structure. Such frameless packs are suitable only for relatively light loads, as the bulk of the weight is transferred solely at two points, namely the shoulders of the user. Additionally, without auxiliary mounting points, the frameless backpack is subject to significant bouncing or swaying as the user runs or jumps.
More substantial pack systems may incorporate either an internal or external, rigid or semi-rigid, load distribution frame. These systems increase the load capability of the user by distributing the weight over a larger area. Additionally, auxiliary mounting points are often utilized to apportion some of the weight to the legs and hips of the user. For example, a robust suspender system, terminating in a load belt, may allow for an interface with the pack's frame. Alternatively, a substantial load carrying belt or back brace may serve as an auxiliary mounting point, exclusive of suspenders. The belt or back brace may be configured of a ballistic or fragmentation resistant material, often referred to as a BLAST Belt™. In this way, an appropriately configured belt will allow the user to alleviate some of the load from his shoulders and transfer it onto his legs and hips. Additionally, the auxiliary mounting point reduces the amount of rucksack bounce and sway that result from user motion. While these frame-based systems improve the user's load carrying capability, they are not readily customizable. Additionally, the fasteners used with the auxiliary belt attachment point often makes attachment and removal much more time consuming when compared with simple frameless designs.
To improve upon the lack of customization encountered with standardized rucksacks, the military implemented a MOdular Lightweight Load-carrying Equipment (“MOLLE”) mounting system. The MOLLE system utilizes a generic frame or vest as a foundation to mount user-selected pouches and accessories. A system of nylon straps, stitched at regular intervals to form a ladder-like pattern, is incorporated into the foundation vest or frame. The user's selected equipment interfaces with coordinating straps interlaced between the ladder stitching of the foundation webbing. The perpendicular straps are secured to the accessory with reusable mechanical fasteners. This interlaced system of perpendicularly woven straps allows the user to mount any of his readily accessible equipment (radios, sidearm, weapon magazines, medical kit, etc.) in a position appropriate for his particular needs. While the MOLLE system does allow for increased user customization, the system does not empower the user to rapidly configure the gear as changes in the activity or mission arise. Additionally, the MOLLE system does not improve upon the speed in which the entire load carriage system is donned and doffed.
Rapid attachment and removal is often not simply a matter of user convenience. For example, during a vehicular crash, rollover, or explosion, a user may be trapped by the bulk and weight of his pack. Additionally, a soldier accidentally thrown into a waterway may be unable to remain buoyant when faced with the additional weight on his back. Lastly, by way of example, various medical injuries require rapid removal of the pack for effective diagnosis and treatment. As one of ordinary skill in the art will recognize, time consuming and complicated mounting systems may significantly reduce user survivability in the above mentioned situations.
The present invention provides a system for rapid mounting and demounting of a user-carried load. The system utilizes a mating connector system, wherein the male portion is mounted to a rucksack, and the female portion is mounted to load bearing belt. The connector system is configured to allow mating under various angles of approach. This greatly facilitates connection reliability and speed, even under conditions wherein the user is unable to view the orientation of the connectors. Additionally, the configuration of the connector system allows the user to quickly and efficiently decouple the connector halves, even while under tensile or shear load.
The present invention includes a load carriage connector for use in human load carriage systems comprising; a male connector half comprising: a back plate; and a mounting knob, in which the mounting knob is coupled to a first side of the back plate, with the mounting knob further defining a circumferential annular groove and a retaining bore, in which the retaining bore comprises a substantially cylindrical hole penetrating a partial distance into a distal end of the mounting knob; and a female connector half comprising: a hub mounting plate, that further comprises a depression that is configured to receive the mounting knob; at least one lock plate that is moveably coupled to the hub mounting plate and biased toward a center of the depression, in which a leading edge of each lock plate cooperates with the annular groove when the mounting knob is seated within the depression such that the mounting knob is restrained against movement in a direction outwardly away from the hub mounting plate; and a retaining arm that comprises a pivot end and a hooked end, with the hooked end being biased toward the retaining bore when the mounting knob is seated within the depression, in which the hooked end engages the retaining bore such that the mounting knob is restrained against lateral movement along a surface of the hub mounting plate.
In one embodiment, the lock plates are constrained to reciprocate linearly. In an alternative embodiment, the lock plates are pivotally mounted to the hub mounting plate.
In a further embodiment, the load carriage connector further comprises at least two lock plates, in which a first end of each lock plate further comprises cooperating gear profiles that are disposed such that pivoting one lock plate toward or away from the depression causes all of the lock plates to simultaneously toward or away from the depression, in which each lock plate moves substantially the same distance.
In another embodiment of the load carriage connector, the distal end of the mounting knob is chamfered. In an additional embodiment, the leading edge of each lock plate is chamfered.
In a further embodiment, the back plate further comprises a block that is located anterior to the mounting knob, in which the block engages with the female connector half such that rotational motion of the female connector half about the mounting knob is prevented.
In a further embodiment, the load carriage connector further comprises a plurality of electrical connectors that are in electrical communication when the male connector half and the female connector half are in a mated configuration.
The present invention further includes a load carriage connector system for carrying a load. In one embodiment, the load carriage connector system comprises: a load carriage connector according to the present invention, in which at least a portion of the load carriage connector is coupled to the load; and at least one load distribution component coupled to the load carriage connector, in which the load distribution component is configured to transfer at least a portion of the load to a user's hips and legs.
In one embodiment of the load carriage connector system, the load distribution component comprises at least one of a load-bearing belt and a vest. In one embodiment, the male connector half is coupled to the load and the female connector half is coupled to the load distribution component. In another embodiment, the female connector half is coupled to the load and the male connector half is coupled to the load distribution component. In a further embodiment, the load carriage connector further comprises a plurality of electrical connectors that are in electrical communication when the male connector half and the female connector half are in a mated configuration.
The present invention provides a load carriage connector and connector system for rapidly attaching and detaching loads. The load carriage connector comprises a male and a female connector half that may be mounted to a load distributor such as a load-bearing belt. As part of a connector system, a ruck pin assembly may be attached to a load such as a rucksack, and the ruck pin assembly engages the load carriage connector. The system may further comprise a tactical vest to which the load is further coupled. The load may be quickly detached and reattached without the need to remove the load-bearing belt and/or the load carriage connector. In addition, the load carriage connector may comprise connectors that allow the two halves to electronically interface.
Civilians and military alike who wear heavy rucksacks (deployed soldiers, campers, rangers, firefighters, hikers, etc.) may benefit from the presently disclosed invention. The presently disclosed load carriage connector and system allows the user to efficiently and evenly distribute the weight of the load and transfer it from the shoulders and spine to the legs, which are better able to carry the weight with less fatigue and injury to the user. In addition, the present invention solves the problem of multiple load-bearing belts. Many modern rucksacks and tactical vests both incorporate load-bearing belts and when worn together, the two loadbearing belts compete for the same space. Users are forced to either layer the two belts (rucksack/vest) or choose to not use the rucksack/backpack belt at all. The present invention allows the rucksack and vest to be coupled together and to share the same load-bearing belt.

The mounting knob 180 is the primary feature of the male connector half 120 that interfaces with the female connector half 140. The mounting knob 180 may be generally cylindrical and may include several features to facilitate effective mating with the female connector half 140. In one embodiment, a circumferential annular groove 182 is formed into a perimeter of an outer surface of the mounting knob 180. The circumferential annular groove 182 is configured to accept a plurality of lock plates 146 (contained in the female connector half 140, described below). The channel walls of the circumferential annular groove 182 are generally parallel to one another, and the channel floor is generally perpendicular to the parallel channel walls. The perimeter of the distal end (the end that is not mounted to the back plate 160) of the mounting knob 180 may include a chamfer 184 to assist in displacing the lock plates 146 (described in more detail in
The embodiment of the female connector half 140 shown in
Additional components are added to the hub mounting plate 142 to retain the mounting knob 180 when it is seated within the depression u-shaped depression 144. One or more lock plates 146 cooperate with the circumferential annular groove 182 to retain the mounting knob 180 while under tensile load. The lock plates 146 are mounted to the hub mounting plate 142 by passing pivot pins (not shown) through pivot holes 147 located near one end (the pivot end) of the lock plate 146. The ends of the pivot pins (not shown) rest in pivot seats 148. The opposite ends of the lock plates 146 are biased concentrically inward by first springs 149. The first springs 149 serve to ensure that the lock plates 146 remain engaged with the circumferential annular groove 182 until the first spring 149 bias is positively overcome by the user's deliberate manipulation of a release mechanism (described below). As one of ordinary skill in the art will recognize, the combination of the circumferential annular groove 182 and the lock plates 146 may be replaced with other suitable mating surfaces sufficient to retain the male connector half 120 under axial tensile loads. Additionally, in lieu of a pivoting configuration, the lock plates 146 may be designed to reciprocate or otherwise slide in a linear motion, biased toward the mounting knob 180. The biasing force may be provided by mechanical springs, resilient leaves, resilient or elastic solids, or other biasing mechanism known to the art.
To aid in ease of connection, the leading edges 143 of the lock plates 146 may be chamfered or radiused to facilitate pivotal displacement by the mounting knob 180. However, the rear face of the lock plates 146 forms substantially right angles to ensure that tensile forces applied to the mounting knob 180 are translated into essentially pure shear forces at the interface between the lock plate 146 and the walls of the circumferential annular groove 182. Some embodiments of the load carriage connector 100 may incorporate cooperating gear profiles 110 into the pivot end of the lock plates 146. These cooperating gear profiles 110 are configured to interlock and translate clockwise rotational forces of one lock plate 146 into counterclockwise rotational forces of adjacent lock plates 146. In this way, a user may pull on either of the release cords 170 attached to any lock plate 146, and multiple lock plates 146 will simultaneously overcome the first spring 149 bias and become displaced from the circumferential annular groove 182. The cooperating gear profiles 110 ensure that each lock plate 146 moves substantially the same distance when the release cord 170 is pulled. The release cords 170 may comprise straps, cords, cables, or any other suitable type of connecting material. Alternatively, the cooperating gear profiles 110 may be omitted for additional load retention security (not shown). In this embodiment, the release cords 170 connected to each of the plurality of lock plates 146 must be simultaneously actuated by the user before the mounting knob 180 is released.
While the lock plates 146 retain the mounting knob 180 against axial tensile loads, the mounting knob 180 is still free to escape from the u-shaped depression 144 by sliding laterally up and out of the top of the u-shaped depression 144. This degree of motion may be restricted by the addition of a retention arm 172. The retention arm 172 may be mounted to the hub mounting plate 142 by way of pivot projections 174 that sit within a pivot boss 176. A second spring 145 biases the hooked end of the retention arm 172 away from the hub mounting plate 142 and into the retaining bore (not shown) of the mounting knob 180 when seated within the u-shaped depression 144. Once the mounting knob 180 is fully seated within the u-shaped depression 144, lateral motion is prevented by the interaction between the hooked end of the retention arm 172 and the retaining bore, while axial movement is simultaneously restricted by the interaction between the lock plates 146 and the circumferential annular groove 182. In an alternative embodiment, the feature interfacing with the retaining bore may be a pin or other projection that is axially biased toward the retaining bore. The projection may be configured with a chamfered leading edge and a perpendicular trailing edge and may be configured such that the approaching mounting knob 180 temporarily axially displaces the projection and the perpendicular edge of the projection traps the mounting knob 180 after it is fully seated in the u-shaped depression 144. While these two embodiments provide illustrative variations of a retaining bore and cooperating biased member, one of ordinary skill in the art will recognize that various “barbed” or “one-way” type latch mechanisms may provide acceptable results.
The components of the female connector half 140 may be shrouded by a receptacle cover 141, which serves to retain the moving components of the female connector half 140 and to assist in the gross alignment of the mounting knob 180 as it approaches the u-shaped depression 144. The receptacle cover 141 may be mounted to the hub mounting plate 142 with a plurality of cover screws 173 and ruggedizing washers 175.

To describe one possible concept of operation, the following narrative is provided. Portions of the load carriage connector 100 have been removed and/or simplified in
In the embodiment depicted in
The user places the arm straps of the rucksack 215 over his or her shoulders in preparation for mounting the load to the load-bearing belt 235. Because of the unique design of the load carriage connector 100, the user may easily couple the load to the load carriage connector 100 even though he or she may have no ability to visually align the components. The user may choose to simply snap the mounting knob 180 axially into the u-shaped depression 144, resulting in an audible click that confirms that the load is secured. In that mounting method, the approaching mounting knob 180 overcomes the first spring 149 bias, allowing the lock plates 146 to temporarily pivot away before snapping back into the circumferential annular groove 182. In this exemplary mode of operation, the retaining arm 172 does not necessitate any movement and remains centered within the retaining bore (not shown).

One end of each support member 327 is coupled to the central lumbar support 329 using a plurality of mechanical fasteners 331, which may comprise rivets, nuts and bolts, or any other suitable mechanical fastener known in the art. Some of the mechanical fasteners 331 may substantially immobilize the support members 327 such that the support members 327 are only able to rotate about the axis of the mechanical fasteners 331. Alternatively, the support members 237 may comprise slots (not shown) that allow the support members 237 to move about the mechanical fasteners 331 such that the support members 237 are displaced laterally toward or away from the central lumbar support 329, as well as being able to rotate about the axis of the mechanical fasteners 331. Each support member 237 is able to move independently, which allows unrestricted user movement while wearing the load-bearing belt 235. The back side of the load-bearing belt 235 may optionally comprise a mesh such as Dri-Lex® Aerospacer® fabric, which is breathable and/or antimicrobial. In addition, the back side of the load-bearing belt 235 may optionally comprise a rubberized or rubber-coated mesh material to prevent slippage and belt rotation.
As one of ordinary skill in the art will recognize, the components of the load carriage connector and/or connector system may be appropriately scaled to allow for rapidly mounting smaller or larger masses. By way of example, the connector and/or system may be scaled down to serve as an effective mounting system for mobile electronic devices, radios, computer terminals, or other small equipment. Likewise, extreme sporting equipment may be rapidly reconfigured by the user to adapt to changes in the type of activity or environmental conditions. Additionally, the connector and/or system may be scaled upwards to effectively couple trailers to vehicles, join modular building sub-assemblies, or couple structures in any environment where precise alignment is difficult to achieve.

For example, a plurality of rucksacks 215 each coupled to a male connector half 120 may be docked with the female connector halves 140. The male connector halves 120 each comprise a plurality of electrical connectors 492 that allow the male connector halves 120 to interface with the female connector halves 140 in the docking station. In another embodiment, the docking station may comprise a plurality of male connector halves 120 mounted on a vertical surface. The male connector half 120 may be connected to electrical power and/or a data source, and rucksacks 215 that are each coupled to a female connector half 140 may be docked. The male connector halves 120 in the docking station and the female connector halves 140 each comprise electrical connectors 492 that allow them to interface.
