Description

Background Art

[0001] There are currently many devices designed to tighten and introduce tension into straps. Current technology in strap tensioning ratchet devices shows that a large portion of these devices utilize a single design. These ratchet designs, which come in a variety of forms and numerous shapes and sizes, suffer from several drawbacks. These issues include: releasing tension from a strap held by the device can be very difficult, the device's performance can significantly degrade over time, and the device's configurability is limited. Furthermore, the device's size and weight can be a burden, particularly for those devices that incorporate permanently attached hooks.

[0002] like Figure 35 Prior Art and Figure 36 Prior Art As shown, a typical prior art ratchet device 400 comprises a chassis 402 and a rotating lever 404, each with a sliding bracket 412, 414. The sliding brackets simultaneously engage a pair of ratchet wheels 406 positioned on two matching hub beams 410, which have a semicircular cross-section. The ratchets are identical in size and shape, namely, circular discs with teeth 408 positioned around their perimeters. The ratchets are located at opposite ends of the hub beams, separated from each other by complementary openings centered on the ratchets. The ratchets are also positioned between the overlapping chassis and lever sidewalls. The two hub beams are constrained within circular openings in the chassis and lever sidewalls, allowing them to rotate freely about their long axes within the circular openings. A spring 430 (either in compression or torsion) acts on the sliding brackets to induce and maintain contact between a blade portion 416 on each sliding bracket and the complementary edge surfaces of a single tooth on each ratchet wheel. The ratchet and hub crossbar are combined to form a single unit and are held in place by a flexible string inserted into a hole near the end of the hub crossbar. The ends of the string then deform, preventing the hub crossbar from being pulled away from the chassis and the joystick. Typically, a large-diameter washer is included to provide a barrier between the string component and the sidewall of the joystick.

[0003] When the lever of the ratchet mechanism is rotated 185° relative to the chassis, a sliding bracket fastened to the lever engages with teeth on each of the two ratchets, causing the ratchets and the hub beam to rotate as a unit within a circular opening in the chassis' sidewall. The sliding bracket in the chassis follows the toothed profile of the ratchets back and forth. When the direction of the lever's rotation is reversed, the sliding bracket in the chassis now engages with a single tooth on each of the two ratchets, preventing the ratchets and the hub beam from rotating, while the lever's sliding bracket is free to follow the corresponding edge profiles on the two ratchets. This alternating rotational movement of the lever creates a ratcheting action that causes the two ratchets and the two hub beams to rotate in a single direction.

[0004] Inserting the end of the webbing into the gap formed between the two hub crossmembers causes the webbing to be wound onto the crossmembers as the lever is rotated. As the webbing is wound onto the hub crossmember, the newly wound webbing overlaps the underlying webbing layer, preventing the webbing from sliding out of the device. The engagement of the blade portion of the chassis slide bracket with the individual teeth on each ratchet retains the tension introduced in the webbing and prevents the hub crossmember and ratchet combination from rotating in a direction that would release tension from the webbing and release the webbing from the device.

[0005] A typical ratchet device permanently attaches one end of a short length of webbing 431 to the ratchet device via a loop sewn into the webbing, which captures a third crossbar 428 permanently secured to the chassis. A hook 432, available in various shapes and sizes, is permanently attached to the opposite end of the short webbing. A second, separate, typically longer length of webbing, also containing a permanently attached hook 258 at one end, completes the components that enable the ratchet device to be used. A possible configuration of the device involves attaching each hook to a separate anchoring location 253, 254, inserting the free end of the longer length of webbing into the gap between the hub crossbars, pulling the webbing through the crossbars until slack is removed from the webbing, and then tensioning the webbing by rotating the ratchet device's lever in alternating directions 185. This back-and-forth rotation of the lever continues until the desired level of tension is introduced into the length of webbing connecting the two anchor points. The length of the lever provides a mechanical advantage, allowing for a greater amount of tension to be introduced into the webbing as the lever is rotated.

[0006] Releasing the tension takes more time. To release the tension, use your index finger to pull the sliding bracket, which is fastened to the lever, back toward the free end of the lever. This allows the lever to rotate freely without engaging the teeth on the ratchet. After rotating the lever approximately 100 degrees, the sliding bracket, which is fastened to the lever, encounters a radially raised portion on the chassis sidewall 424. Releasing the lever sliding bracket in this position causes the sliding bracket to contact the raised platform on the chassis sidewall, which in turn prevents the sliding bracket on the lever from engaging the teeth on the two ratchets. As the lever is rotated further, the eccentric end of the lever arm 418 begins to engage the blade end 416 of the sliding bracket 412, which is trapped in the chassis 402, causing the sliding bracket to move radially outward relative to the hub crossbar and ratchet. When the lever is rotated approximately 170 degrees, the eccentric portion of the lever has rotated far enough to completely disengage the sliding bracket in the chassis from the teeth located on the periphery of the ratchet. With the sliding bracket in the lever previously disengaged and now the sliding bracket in the chassis also disengaged, there is no remaining means to prevent rotational movement of the hub beam and ratchet. The tension present in the webbing will cause the hub beam and ratchet to rotate in a direction opposite to the direction of the previous ratchet action, thereby releasing the stored tension from the webbing.

[0007] In most ratchet systems, there is a notch 403 in the edge profile of the chassis side wall that engages a sliding bracket on the lever when the lever is rotated to the fully open position to lock the lever in place. This creates a rigid configuration between the lever and the chassis, while the hub beam and ratchet are still free to rotate, allowing the webbing to be pulled out of the system. At lower levels of introduced tension, this tension release mechanism works well enough. However, with repeated use or use near the rated working load limit, the components of most ratchet systems begin to wear and / or deform, making removing the webbing from the system increasingly frustrating. In situations where the system is tightly constrained by surrounding structure (such as the bed area of ​​a truck), a locked lever can hinder rather than enhance the removal of the webbing from the ratchet system.

[0008] Furthermore, when the lever is rotated toward the tension-release position, even though the eccentric pushes the chassis sliding bracket toward the release point, the force required to rotate the eccentric at the end of the lever is compromised due to the poor mechanical advantage provided by the lever. At high webbing tension levels, or in cases of excessive wear on the device, it is common for the release action to begin to mimic the bowstring of a bow and arrow device. This requires significant force in a direction perpendicular to the string (in this case, the webbing), so the mechanical advantage gained from the length of the lever and the shape of the eccentric at the end of the lever is offset by the lack of restraint in the device. This behavior may require the operator to provide additional leverage when releasing webbing tension, either by physically limiting the displacement of the ratchet mechanism or, perhaps, by inserting a long-shaft screwdriver between the hub crossbar and the lever to force the lever to rotate relative to the chassis. Both methods are commonly used and pose safety risks to the device's operator.

[0009] In ratchet devices incorporating a sliding carriage, the area of component distortion that typically occurs during the webbing tension release action is at the interface 433 between the lever eccentric and the blade end of the chassis sliding carriage. This contact area experiences a high level of localised stress within the device. As tension is released from the device, the lever eccentric moves the chassis sliding carriage outwardly to disengage the sliding carriage from the ratchet teeth. This particular component to component engagement typically occurs on the edge face of the sliding carriage and the two eccentric shaped ends on the lever, thus concentrating a large amount of force into a relatively small area. An inspection of well used current technology ratchet devices, particularly those that utilise a die cast lever, will show excessive wear and / or distortion in these device locations. Over time, the cumulative effect of these distortions will permanently alter the ratchet device. The amount of travel introduced into the chassis sliding carriage by the eccentric shape on the lever end can no longer be sufficient to move the sliding carriage far enough to disengage the sliding carriage from the ratchet teeth. At this point, tension release is accomplished by severing the webbing or forcibly releasing the chassis sliding carriage from the ratchet teeth using supplemental tools.

[0010] This failure mode occurs in ratchet devices that utilise a sliding carriage to actuate the ratchet action. Over the years, the efforts made by various manufacturers to mitigate this problem have resulted in a large number of design solutions. However, in most cases, these devices are essentially the same and so are the failure behaviours.

[0011] Typically, both the lever and the chassis side walls contain slots 420, 422 that constrain the sliding carriage. These slots allow the sliding carriage to move back and forth within the slots. Lateral displacement and rotational displacement are also enabled in the sliding carriage (both occur within the planes 426, 427 defined by the opposing side wall slots), but are not relevant to the intended function of the device.

[0012] When the lever is rotated to introduce webbing tension, the end of the blade portion 416 of the sliding carriage that is constrained in the lever engages the teeth on the ratchet, thus rotating the ratchet and hub beam. The blade end of the sliding carriage in the lever and chassis can be designed to be of sufficient size to ensure contact with the ratchet teeth, the chassis side wall slots, the chassis side wall edge profile and the lever side wall slots. In addition, to accommodate the possible lateral and in-plane rotational movements of the sliding carriage, the width of the sliding carriage can be increased accordingly.

[0013] The introduction tension in the webbing forces the edge faces of the ratchet teeth into the blade end portion of the sliding bracket, which is simultaneously pressed into the edge of the slot in the joystick bracket or chassis bracket. This action is like cutting paper with scissors, where the paper is the blade portion of the sliding bracket. This contact force is concentrated in a small area on the blade face, making the integrity of the blade entirely dependent on the material properties and thickness of the blade material at the blade end. The width requirement previously noted, combined with the additional burden of providing sufficient gap around the webbing configured in the device, precludes the introduction of blade stiffening geometries (where they would help prevent deformation of the blade end under higher force loads).

[0014] The possibility of lateral translational movement and in-plane rotational movement of the sliding bracket creates another serious disadvantage for current ratchet devices. This can result in only one tooth on one ratchet wheel engaging the sliding bracket, or one tooth fully engaging while the tooth on the other side is only partially engaged. In both cases, both ratchets are no longer fully engaged. While creating an unsafe condition, the imbalance in load sharing can easily cause the sliding bracket to deform at the blade portion that engages the ratchet teeth. Since the blade on the sliding bracket is now deformed, subsequent use of the device becomes difficult.

[0015] Another cause of this misalignment, especially in lower quality, lower load-rated units, is that the chassis itself will twist about its long axis as tension is ratcheted into the webbing. This behavior is similar to wringing water out of a wet towel and will cause the chassis slide bracket to fall into an unbalanced load-sharing position relative to the ratchet teeth.

[0016] To mitigate misalignment of the sliding bracket, some manufacturers add knurling 429 to the sliding bracket to keep the bracket centered between the sidewalls of the joystick or the sidewalls of the chassis. However, if the knurling is located too close to the chassis and joystick sidewalls, the sliding bracket can bind; if it is not close enough, the sliding bracket can rotate out of parallel as described above. Both of these effects are observed in currently available ratchet devices. This is a design limitation of the sidewall groove / sliding bracket interaction in current technology ratchet devices and is a source of frustration for those who use such devices.

[0017] In order to minimize the weight of the device and create a unique appearance, some manufacturers utilize die-cast levers in aluminum or zinc alloy. These types of levers may incorporate specific geometric shapes (instead of open slots) to serve as channels or guides for the slide bracket. However, the blade ends of the harder slide bracket material tend to wear away and / or scrape away the softer die-cast material on the lever eccentric portion located at the end of the lever. Repeated use at or near the working load limit can affect and eventually damage the die-cast eccentric surface, rendering the device ineffective and preventing the release of the ratchet tension. In this case, the means available to release the tension from the webbing is either to cut the webbing or to use auxiliary tools to forcibly release the chassis slide bracket (an often dangerous proposition).

[0018] Finally, when considering competing configurations - device, strap, hook (Figure 35 prior art) - additional disadvantages emerge that limit the overall effectiveness of the current art ratchet device. As previously mentioned, the ratchet device has one anchor point, which is the attachment portion of the short length of webbing and hook sewn to the device. This arrangement limits the locations where the ratchet device can be positioned. The user is often unable to obtain ideal access when tensioning or releasing tension from the ratchet device. In addition, ratchet devices with permanently attached straps and hooks can be heavy, requiring special care when initially configuring the ratchet device, strap, and hook to prevent damage to surrounding objects. Summary of the Invention

Furthermore, the features incorporated into this embodiment provide a novel means for enabling a variety of strap and hook configurations not available in the prior art.

[0216] Certain terms are used herein for convenience only and should not be construed as limiting embodiments of systems and methods of improved ratchet devices including pivot teeth (enhanced ratchet mechanisms). In many embodiments of the enhanced ratchet mechanism, the device includes a first pivot tooth that interfaces with the ratchet wheel. This is in contrast to many prior art devices that utilize a sliding bracket that interfaces with the ratchet wheel. In many embodiments, the first pivot tooth is mounted on a first pivot bracket. The first pivot bracket allows the first pivot tooth to pivot away from the ratchet wheel, resulting in improved performance and wear of the enhanced ratchet mechanism. In many embodiments, the device additionally includes a second pivot tooth that interfaces with the ratchet wheel. In many embodiments, the second pivot tooth is mounted on a second pivot bracket. The second pivot bracket allows the second pivot tooth to pivot away from the ratchet wheel. The pivot brackets are mounted on corresponding lever arms, allowing the brackets, and therefore the teeth, to rotate away from the ratchet wheel, thereby rotating to provide tensioning of the strap. Furthermore, in many embodiments, the teeth of the ratchet wheel and the first and second pivot teeth have circular and complementary shapes, such that when the lever arm moves in a first rotational direction, a first of the first and second pivot teeth flexes rearward and ratchets, and when the lever arm moves in a second rotational direction, a second of the first and second pivot teeth flexes rearward and ratchets. This ratcheting method follows the arcuate surface of the ratchet wheel, so that when the first or second tooth ratchets, it slides smoothly on the ratchet wheel and generally follows the shape of the ratchet wheel.

[0217] Embodiments of the enhanced ratchet mechanism offer numerous advantages and features. Some embodiments herein provide a ratchet device that effectively doubles the tension-introducing capacity of a similarly sized prior art ratchet device. Some embodiments enable the device to be attached and detached at any location along the strap without requiring access to either end of the strap. Some embodiments allow the strap to be routed before the ratchet device is attached and positioned on the strap. Some embodiments permit, but do not require, the use of anchor hooks at the strap ends. While utilizing materials similar to those found in prior art ratchet devices, some embodiments provide a more durable and less susceptible to damage interface at the device's load-bearing position. Some embodiments provide a reliable tension-releasing action suitable for releasing high tension levels while providing convenient access to the strap to assist in its removal. These and other advantages of one or more aspects will become apparent upon consideration of the following description and accompanying drawings.

[0218] Figure 1 One embodiment of an enhanced ratchet mechanism 100 is shown. Figure 1 An isometric view of the enhanced ratchet mechanism 100 is shown in the closed position. Figure 1In this view, the cross-sectional line A is shown. In addition, pin 119 is also shown. Pin 119 can be used to lock the enhanced ratchet mechanism in an inoperable position for sale or shipping. In essence, pin 119 locks pawl holder 141 into place, which prevents ratchet 131 from turning, thus locking pawl holder 141 to the rest of the body of the device.

[0219] Figure 2a An isometric view of enhanced ratchet mechanism 100 is shown, with the capture frame assembly and lever in the open position. The arrows indicate the direction of relative movement of the lever, capture frame assembly, lever pivot pawl holder, chassis pivot pawl holder, both ratchets, and both hub cross members. In this view, many important features can be seen. First, in this view, it can be seen that the ratchet system has two pivot / rotation holders, one that rotates in direction of travel 186, and one that rotates in direction of travel 187. The rotation of these two holders, chassis pivot pawl holder 141 and lever pivot pawl holder 151, greatly enhances the operation of the device. This is because their rotation provides smooth ratcheting along ratchet 131 and / or release from ratchet 131. This greatly improves the usability and performance of the device. In addition, visible here is capture frame assembly 170. This portion of the enhanced ratchet mechanism is important to the operation of the device, as it provides an attachment area that allows for the end of a flat strap or along a flat strap to be secured and releasably interconnected, thus providing the user with the opportunity to use the device without having to tie the flat strap. Figure 2b Another view of enhanced ratchet mechanism 100 in the open position is shown.

[0220] Figure 3 An exploded view of enhanced ratchet mechanism 100 is shown. In this view, various details of the device can be seen. Much of what is in this view is important, some of which will be explained in detail below. One of the many important aspects is the shape of ratchet teeth 132 relative to the shape of teeth 153 of lever pivot pawl holder 151 and teeth 143 of pivot pawl holder 141. These teeth have a smooth and complementary shape that allows them to smoothly slide over one another. In addition, it is important to note that torsion springs 194, 195 are used to provide rotational tension and force to lever pivot pawl holder 151 and pivot pawl holder 141. Of course, these springs are exemplary only, and other types and locations of springs can be utilized. For example, a coil spring could be located between the pivot holders and rest against the frame to provide rotational force. This is just one example, and many others will come to mind to those skilled in the art. In addition, the form factors shown here, and their relative sizes, are exemplary only, and many different embodiments can utilize different sized pieces and configurations.

[0221] Figure 4aAn open view of the enhanced ratchet mechanism 100 is shown. Figure 4b An open view of the enhanced ratchet mechanism 100 is shown. Figure 4a The ratchet 131, the hub beam 134, the two spacers 196, the two wire locks 197, and the lever and chassis side walls will have similar parts as the prior art ratchet device Figure 36 Prior Art Please note that the front parts 101' and 102' do not really exist in the enhanced ratchet mechanism 100 as these areas form part of the side walls of the chassis. Also, although the enhanced ratchet mechanism 100 can have a ratchet like the prior art device, the shape of the teeth / gears can not be found in the prior art device. Please note that the dashed areas are shown to depict non-owned parts. Figure 4c An open view of the enhanced ratchet mechanism 100 is shown. Figure 4b An exploded view from a different perspective is shown.

[0222] Figure 5 A cross-sectional view of the enhanced ratchet mechanism 100 through the longitudinal plane AA defined in Figure 1 The lever pivot pawl bracket 151 is partially open allowing the lever 121 to freely rotate. This clearly indicates that in the embodiment shown, the lever 121 is resting on the ratchet via the lever pivot pawl bracket 151. When the lever pivot pawl bracket 151 is pivoted open, the lever 121 can freely rotate relative to the ratchet 131. Also, to improve visibility of the ratchet details, a portion of the chassis side wall has been cut away near the ratchet. As shown, the position of the chassis pivot pawl bracket 141 preserves the ratchet tension introduced in the webbing. The chassis pivot pawl bracket 141 prevents the chassis side walls 101, 102 from freely rotating relative to the ratchet 131. Figure 5 The webbing is not shown in

[0223] Figure 6 A cross-sectional view of the enhanced ratchet mechanism 100 through the longitudinal plane AA defined in Figure 1 The lever pivot pawl bracket 151 is positioned to introduce tension in the webbing as the lever is rotated. The teeth 153 on the lever pivot pawl bracket engage with the teeth 132 located on the periphery of the ratchet 131. Also, to improve visibility of the ratchet 131 details, a portion of the chassis side wall has been cut away near the ratchet. As shown, the position of the chassis pivot pawl bracket 141 preserves the ratchet tension introduced in the webbing. Figure 6 The webbing is not shown in

[0224] Figure 7a and Figure 7b An isometric view of the enhanced ratchet mechanism 100 is shown, positioned to initiate tension release from the webbing configured in the present embodiment. The lever travel direction to perform the tension release is also shown in the figure. Figure 7a or Figure 7b The webbing is not shown in these configurations. In these configurations, the joystick pivot pawl bracket 151 rotates and engages with the chassis pivot pawl bracket 141 such that the joystick pivot pawl bracket 151 pushes the chassis pivot pawl bracket 141 into a position rotated away from the ratchet wheel 131, the chassis pivot pawl bracket 141 holds the joystick pivot pawl bracket 151 in the rotated position. In such a configuration, neither bracket is engaged with the ratchet wheel 131, the ratchet wheel 131 can freely rotate.

[0225] Figure 8a and Figure 8b An isometric view of the enhanced ratchet mechanism 100 is shown at the end of the tension release action. Note the relative positions of the joystick, chassis, and joystick pivot pawl bracket. In this position, the joystick pivot pawl bracket 151 has moved the chassis pivot pawl bracket 141 off of the ratchet wheel 131, disengaging the chassis pivot pawl bracket 141 from the ratchet wheel. The hub beam 134 can now freely rotate in either direction, allowing the webbing configured in this embodiment to be easily pulled off of the hub beam 134. Figure 8a or Figure 8b The webbing is not shown in these configurations.

[0226] Figure 9a and Figure 9b An isometric view of the enhanced ratchet mechanism 100 is shown with the webbing positioned as in Figure 7a and Figure 7b An isometric view and cross-sectional view of the longitudinal plane AA defined in Figure 1 is shown. Note the engagement of the chassis pivot pawl bracket teeth 143 with the ratchet wheel teeth 132. Also note the complementary structure of the teeth, where the voids of teeth 132 are completely filled by teeth 143. Figure 9a or Figure 9b The webbing is not shown in these configurations.

[0227] Figure 10a and Figure 10b An isometric view of the enhanced ratchet mechanism 100 is shown with the webbing positioned as in Figure 8a and Figure 8b An isometric view and cross-sectional view of the longitudinal plane AA defined in Figure 1 is shown. Note that both the chassis pivot pawl bracket teeth 143 and the joystick pivot pawl bracket teeth 153 are completely disengaged from the ratchet wheel teeth 132. The joystick pivot pawl bracket 151 has disengaged from the ratchet wheel 131 before the chassis pivot pawl bracket 141 disengages. Using the back end of the joystick pivot pawl bracket 151 (tab 155) as the mechanism to disengage the chassis pivot pawl bracket 141 from the ratchet wheel 131 ensures that the joystick pivot pawl bracket 151 will disengage first. Figure 10a or Figure 10b The webbing is not shown in these configurations.

[0228] Figures 11a to 11d The capture frame components are shown in four unique positions; locked, unlocked, open, and unconstrained. Figure 1 1 and 2. A cross-sectional view of the enhanced ratchet mechanism 100 taken along a longitudinal plane AA defined in FIG. The webbing configured in the capture frame assembly is not shown in the figure.

[0229] Figures 12a to 12d Repeated Figures 11a to 11d An isometric view is shown with the addition of a single layer of webbing 240 configured in a capture frame assembly. This would be representative of a single strap in a fixed end configuration (Figure 19). Note that Figure 12d The capture frame assembly in allows the enhanced ratchet mechanism 100 to move freely in either direction along the webbing.

[0230] Figure 13 Shown by Figure 1 FIG2 is a cross-sectional view of the enhanced ratchet mechanism 100 taken along longitudinal plane AA defined in FIG2 . This embodiment is removably secured to a length of webbing. The capture frame assembly is shown in a locked position. As long as the tension in the upper webbing length, as configured in this embodiment, is greater than the tension in the lower webbing length, the enhanced ratchet mechanism 100 is prevented from moving along the webbing in the direction indicated by the arrow. In this case, the higher tension webbing overlies the lower tension webbing at the center shoulder pin of the capture frame assembly.

[0231] The enhanced ratchet mechanism is not prevented from moving in the reverse direction along the webbing. Movement or lack thereof in the reverse direction is not critical to the proper operation of this embodiment. If this embodiment were used with thick or stiff webbing, movement in the reverse direction could be hindered.

[0232] Figure 14a Shown by Figure 1 25 . A cross-sectional view of the enhanced ratchet mechanism 100 taken along longitudinal plane AA defined in FIG. 26 . The embodiment is removably secured to the webbing. The capture frame assembly is shown in a locked position with the webbing configured in the enhanced ratchet mechanism in a tethered anchor configuration ( FIG. 25 ). The free end of the webbing is captured between the load-bearing portion of the webbing and a forwardly positioned crimped lower shoulder pin. In this configuration, the embodiment is prevented from moving in the direction indicated by the arrow. The overlay of the higher tension webbing over the lower tension webbing occurs at the crimped lower shoulder pin where the tethered anchor webbing enters and exits the enhanced ratchet mechanism through a gap formed between the two crimped lower shoulder pins.

[0233] Figure 14b Shown by Figure 11 is a cross-sectional view of the enhanced ratchet mechanism 100 taken along longitudinal plane AA defined in FIG. This embodiment is removably secured to the webbing. The capture frame assembly is shown in a locked position, wherein the webbing configured in this embodiment is in a tethered anchor configuration, wherein the free end of the webbing is not trapped between the load-bearing portion of the webbing and the forwardly positioned, crimped lower shoulder pin. In this configuration, the embodiment is prevented from moving along the webbing in the direction indicated by the arrow. The overlay of the higher tension webbing over the lower tension webbing occurs at the center shoulder pin of the capture frame assembly.

[0234] Figures 15a to 15h A series of isometric views are shown depicting the progressive advancement of removably securing the enhanced ratchet mechanism 100 to a length of webbing using a capture frame assembly. Only the capture frame portion and the front ends of the chassis sidewalls A and B of this embodiment are shown. When the capture frame assembly is in the locked position, as shown in FIG. Figure 15h and Figure 13 As shown, the enhanced ratchet mechanism is prevented from moving along the webbing in the direction indicated by the arrow. When the capture frame assembly is in the unrestrained position, as shown Figure 15e and Figure 12d As shown, this embodiment allows movement in either direction along the webbing.

[0235] Figures 16a to 16g A series of isometric views are shown depicting the step-by-step process of removably securing the enhanced ratchet mechanism 100 to a length of webbing. Access to the ends of the webbing is not required when securing the enhanced ratchet mechanism to the webbing. The enhanced ratchet mechanism is secured to the webbing with the aid of a capture frame assembly. The enhanced ratchet mechanism is removed from the webbing by reversing the illustrated advancement process. To remove the enhanced ratchet mechanism from the webbing, the tension in the webbing must first be released. Figure 16g The enhanced ratchet mechanism is shown secured to the webbing and the capture frame assembly is in a locked position, preventing movement of the embodiment along the webbing in the direction indicated by the arrow.

[0236] Figures 17a to 17d A series of isometric views are shown depicting the step-by-step process of deploying the webbing in the tensioning portion of the ratchet mechanism of the enhanced ratchet mechanism 100 and then introducing tension into the webbing using the lever of the enhanced ratchet mechanism. The reaction force 2F at the anchoring location is twice the tension F introduced by the ratchet portion of the enhanced ratchet mechanism 100.

[0237] Figures 18a to 18eA series of isometric views are shown depicting the step-by-step progression of the enhanced ratchet mechanism 100 being configured in a fixed end configuration. The tension release action requires a single hand, simultaneously, to flip the lever pivot pawl bracket with the thumb while positioning the lever and lever pivot pawl bracket into a mating position with the chassis pivot pawl bracket. The webbing tension release is then accomplished by pulling the lever and chassis together. The mechanical advantage afforded by the geometry of the lever and two pivot pawl brackets allows for the release of hundreds of pounds of introduced webbing tension with only a modest force input, all of which can be easily accomplished using a single hand.

[0238] Figures 19a to 19i A series of isometric views are shown depicting the step-by-step progression of the enhanced ratchet mechanism 100 being secured to a strap that contains a sewn-in loop on one end. This progression depicts a fixed end configuration followed by tensioning with the enhanced ratchet mechanism 100. The fixed end configuration consists of a strap spanning the distance between two anchor locations, with the strap attached in some manner at each anchor location. Unlike current technology ratchet devices, a single removable strap is used, allowing the enhanced ratchet mechanism 100 to be positioned anywhere along the length of the strap.

[0239] Figures 20a to 20h A series of isometric views are shown depicting the step-by-step progression of the enhanced ratchet mechanism 100 being secured to a length of webbing. Neither end of the webbing contains any type of treatment; a sewn-in hook, a sewn-in end loop, or otherwise. This progression depicts a fixed end configuration, where the enhanced ratchet mechanism 100 is used to pull tension into the webbing spanning the distance between two anchor locations. This configuration (using a single detachable strap with no end treatment) is not possible with current technology ratchet devices. The enhanced ratchet mechanism 100 can be attached anywhere along the length of the webbing.

[0240] Figures 21a to 21h A series of isometric views are shown depicting the step-by-step progression of the enhanced ratchet mechanism 100 being secured to the end of a strap that contains a sewn-in end loop. The embodiment with the attached strap is then configured in a loop configuration spanning three anchor locations. This embodiment and strap are the same as used in Figure 19, demonstrating the versatility of this embodiment in creating multiple configurations. Current technology ratchet devices are typically manufactured to function in only a fixed end or loop configuration.

[0241] Figures 22a to 22fA series of isometric views are shown depicting the step-by-step process of tightening the enhanced ratchet mechanism 100 onto the end of a length of webbing. The ends of the webbing do not include end treatments. This embodiment, with the attached webbing, is then configured in a loop configuration spanning three anchoring locations. This embodiment and webbing are identical to those used in FIG20 , illustrating the versatility of this embodiment in creating a variety of configurations using interchangeable straps of varying lengths. Current art ratchet devices cannot be used independently of the permanently attached straps with which they are manufactured.

[0242] Figures 23a to 23h A series of isometric views are shown depicting the step-by-step progression of securing the enhanced ratchet mechanism 100 to a short strap containing sewn end loops that are secured to an anchoring location, and subsequently using a second length of webbing containing permanently attached hooks to form a fixed end configuration between the two anchoring locations. The short strap can be sized to the appropriate length to best suit the application. The enhanced ratchet mechanism 100 can be attached to the short strap at any location along the strap. Note that the use of a removably attached strap enables the combination of the strap and the first embodiment to be secured to a variety of anchoring locations that might otherwise prove unsuitable for sewn straps containing sewn hooks. This type of connection is known as a tethered anchor.

[0243] Figures 24a to 24h The same sequence as in Figure 23 is shown, with the short strap being removably fastened to the hook. The arrangement shown replicates the arrangement primarily used in prior art ratchet arrangements ( Figure 35 Prior Art ), the primary difference being that the enhanced ratchet mechanism 100 is not permanently attached to the hook or shorter strap, thereby retaining its ability to be used in other configurations.

[0244] Figures 25a to 25f A series of isometric views are shown depicting the step-by-step progression of securing the enhanced ratchet mechanism 100 to a short length of webbing tied to an anchor location, and subsequently using a second length of webbing containing permanently attached hooks to form a fixed-end configuration between the two anchor locations. The tethered anchor attachment provides a high degree of versatility when securing to an anchor location. Such anchoring options are not available in current art ratchet devices that utilize permanently attached anchor straps.

[0245] Figures 26a to 26hA series of isometric views are shown depicting the step-by-step progression of tightening the enhanced ratchet mechanism 100 onto a length of webbing comprising sewn-on end loops and two removably attached S-shaped hooks, followed by anchoring between two fixed locations to form a fixed-end configuration. The sequence shown is similar to that depicted in FIG24 , except that a single strap is used instead of two straps. The induced stresses in the ratchet portion of embodiment 100 are comparable to those of prior art devices, but the magnitude of the reaction forces at the anchoring locations is effectively doubled ( ). Figure 17d , Figure 35d Prior Art). This represents a significant advantage over current technology.

[0246] Figures 27a to 27e A series of isometric views are shown, depicting the step-by-step process of fastening the enhanced ratchet mechanism 100 to a strap comprising sewn-in end loops. Before the strap is fastened to the enhanced ratchet mechanism, the end comprising the sewn-in end loops is passed around an anchor point and then folded back on itself. The sewn end loops and the underlying strap are then secured by the capture frame assembly. The free end of the strap exiting the bottom of the enhanced ratchet mechanism 100 is passed around a second, distant anchor point before being reintroduced into the ratchet portion of the enhanced ratchet mechanism. Compared to FIG19 , this configuration effectively doubles the load-bearing capacity of the strap configured in this device. The enhanced ratchet mechanism 100 can be attached at any position along the length of the strap.

[0247] Figures 28a to 28f A series of isometric views are shown depicting the step-by-step advancement process of fastening the enhanced ratchet mechanism 100 to a strap containing sewn-on end loops and subsequently using a second strap containing permanently attached hooks to form a fixed end configuration between two anchor locations. The initial steps of the advancement process are similar to those of FIG. 27 , except that a short strap forms the tether anchor. This provides the user with the option of using a lighter weight webbing as a tether anchor strap without sacrificing the load-bearing capacity at the tether anchor. However, please note that the doubling effect of the ratchet action described in the other figures ( FIG. 27 ) does not work in this configuration. This configuration is functionally similar to the typical configuration used by current technology devices.

[0248] Figures 29a to 29f The same sequence as in FIG28 is shown, with the short strap removably securing the hook. This configuration is comparable to the ratchet tensioning capability and anchoring configuration of current technology devices ( Figure 35 Prior Art ) closely matches. However, compared to current art devices that are limited to a single location, the tethered anchor provides additional versatility that allows for selective placement of this embodiment along the strap. By configuring a flat strap with a sewn-on loop at one end to pass through and form a loop at one end of the enhanced ratchet mechanism 100, a hook can be used to provide tension via both hooks.

[0249] Figure 30a and Figure 30b An alternative embodiment is shown in an open and webbing-locked position, in which the capture frame assembly of embodiment 100 is replaced with an "S-shaped" string to lock the embodiment to the webbing. The capture frame assembly of embodiment 100 is replaced with a capture assembly 3000 with an "S-shaped" capture beam 3010 (or string) for locking the embodiment to the webbing. In the illustrated embodiment, string 3000 is oriented to receive a flat webbing (webbing—note that the terms webbing, flat webbing, and flat webbing may all be used herein to describe the material used with embodiments of the enhanced ratchet mechanism) and then rotated into position, where the S-shaped capture beam 3010 rests against the first and second capture notches 3020 and 3030 in an interference fit arrangement, thereby providing securement of the S-shaped capture beam 3010. Furthermore, when the flat webbing is applied, the tension on the flat webbing will retain the S-shaped capture beam 3010 in the notches.

[0250] Figure 31a and Figure 31b An alternative embodiment is shown in the open and webbing locked position where the capture frame assembly of embodiment 100 is replaced with a die cast component to utilize a separate capture ring and sidewall knurling 3110 to lock the embodiment to the webbing and hold the floating post 3175 in place. Figure 32a and Figure 32b An alternative embodiment is shown in an open and webbing locked position, where the capture frame assembly of embodiment 100 is replaced with a formed sheet metal component that utilizes a separate capture loop 3220 and crossbar 3210 to lock the embodiment to the webbing.

[0251] Figure 33 An isometric view of an alternative embodiment is shown that incorporates a cam lock 3310 with the capture frame assembly, replacing the ratchet portion of the enhanced ratchet mechanism. Cam lock 3310 is a spring-loaded cam lock in which tension on the flat strap of the alternative embodiment away from the enhanced ratchet mechanism causes cam lock 3310 to rotate and clamp. Cam lock 3310 can be released via a press area 3320. Figure 34 Shows the Figure 33 Isometric view of an alternative embodiment configured with webbing to form a fixed end configuration.

[0252] Figure 39a Chassis components from the previously shown enhanced ratchet mechanism 100 are shown. Figure 39b A single chassis component 109 is shown as a possible replacement of existing chassis components from the enhanced ratchet mechanism 100 . Figure 40Shown are chassis 110, chassis pawl bracket 149, and chassis pawl bracket pivot pin 11, coil spring 201 from an alternative chassis configuration 360. This configuration provides a different way of connecting the sides of the chassis.

[0253] In one embodiment, the enhanced ratchet mechanism 100 includes: chassis side walls A 101 and B 102, which are attached to each other in parallel by means of crimped lower shoulder pins 111 and 112; an operating lever 121; two ratchets 131, each of which includes a plurality of teeth 132 located at a periphery and a central cross member 138; two hub cross members 134 having a semicircular cross section; two spacers 196; two linear locks 197; a chassis pivot pawl bracket 141, which is attached to the chassis side walls by means of a crimped pivot pin 191; an operating lever pivot pawl bracket 151, which is attached to the operating lever by means of a crimped pivot pin 192; and a capture frame assembly 170, which includes two side plates A 171 and B 172. 172 (including the arcuate area 1172 for guiding the shoulder pin 173), the crimped center shoulder pin 173 and the crimped lower shoulder pin 113, which together fasten the side panel A to the chassis side wall A and the side panel B to the chassis side wall B respectively. In some places, the pin 173 is referred to as the second pin. In addition, a self-standing post 175 is crimped on the side panel A. In some descriptions herein, the self-standing post 175 may be referred to as the third pin. These aspects are as follows Figure 1 、 Figure 2a 、 Figure 2b 、 Figure 3 It is important to note that all of these aspects are exemplary and that one of ordinary skill in the art would appreciate that the arrangement could be different, with different components (or omitted components). For example, in alternative embodiments, the ratchet wheels may not be identical; different teeth may be utilized on each wheel or wheels of different sizes may be utilized, and in most cases, the wheels interface with the teeth and the carrier that carries the teeth in a useful manner.

[0254] Side panel A includes a slotted opening 176 that allows the side panel to rotate and translate about a centrally located crimped shoulder pin 173. Side panel B is rigidly fastened to chassis side wall B by means of the centrally located crimped shoulder pin 173 and one of the crimped lower shoulder pins 113. Side panel B includes an open slot 177 and arm supports 169 along the edge of the panel.

[0255] A torsion spring 194 biases the chassis pivot pawl bracket 141 to maintain contact with the peripheral edge surface 139 of the ratchet 131. A torsion spring 195 biases the joystick pivot pawl bracket 151 to maintain contact with the peripheral edge surface 139 of the ratchet 131. A crimped pivot pin 191 provides attachment and pivoting means for the chassis pivot pawl bracket 141. A crimped pivot pin 192 provides attachment and pivoting means for the joystick pivot pawl bracket 151. An additional pin 193 acts as a hard stop for the joystick pivot pawl bracket 151 and as a spring stop for spring 195, which biases the joystick pivot pawl bracket. Furthermore, a pad 161 is positioned below the joystick pivot pawl bracket 151 and is restrained by the joystick pivot pawl bracket and the pin 192 that secures the joystick pivot pawl bracket to the joystick 121. The washer 161 centers the spring 195 laterally along the pivot pin 192 within the lever pivot pawl bracket side wall 152. A handle 129 is permanently attached to the free end of the lever 121. Figure 1 、 Figure 2a 、 Figure 2b 、 Figure 3 Note that throughout this description, chassis pivoting pawl bracket 141 and lever pivoting pawl bracket 151 are described as pivoting brackets. In many cases, pivoting brackets can be an effective technology for enhanced ratchet mechanisms. However, not all pivoting brackets are like this. To achieve the functionality of many operational forms of the enhanced ratchet mechanism, it is necessary to rotate the teeth on each side of the enhanced ratchet mechanism from a position engaging the wheel to a position disengaging the wheel. When ratcheting to provide tension, the teeth on one side of the ratchet mechanism slide over the teeth on the wheel, while the teeth on the other side of the ratchet mechanism remain in position. Then, once the lever arm is extended, the operation is reversed, whereby the teeth on the other side of the ratchet mechanism slide over the teeth on the wheel, while the teeth on the first side of the ratchet mechanism remain in position. Therefore, the mechanism carrying the teeth does not necessarily have to be a rotating bracket, but simply a structure that allows the teeth on each side of the ratchet mechanism to rotate into and out of engagement with the wheel. In many configurations, having two sets of teeth that move in unison is useful; however, various configurations of teeth and wheels can be used, including but not limited to varying the number of teeth, tooth size, number of wheels, and wheel size.

[0256] Additionally, the webbing guide 199 and bottom shield 198 snap fit between selected crimped shoulder pins to help guide the webbing through this embodiment. Figure 1 、 Figure 2a 、 Figure 2b 、 Figure 3 .

[0257] The chassis pivot pawl bracket 141 is secured to the chassis sidewalls A and B 101, 102 by means of a pivot pin 191 end which is crimped or press-fitted into or into a circular opening 144 in each chassis pivot pawl bracket sidewall 142 and extends through a circular opening 103 in each chassis sidewalls A and B 101, 102. The pivoting action of the chassis pivot pawl bracket is actuated by a compressed torsion spring 194 which is positioned on the crimped pivot pin 191 with the spring legs pressing against the crimped lower shoulder pin 111 and the spring center portion pressing against the bottom of the chassis pivot pawl bracket 141. The chassis pivot pawl bracket 141 is free to rotate in either direction 187 within the confines of the ratchet wheel 131 and the chassis sidewalls A and B 101, 102. Figure 1 、 Figure 2a 、 Figure 2b 、 Figure 3 .

[0258] A capture frame assembly 170 is confined within the chassis. The capture frame assembly includes two side panels, A 171 and B 172 ; a crimped center shoulder pin 173 that removably secures side panel A to chassis sidewall A 101 through a slotted opening 176 in side panel A and rigidly secures side panel B to chassis sidewall B 102 through a circular opening 179 in side panel B. A crimped lower shoulder pin 113 also secures side panel B rigidly to chassis sidewall B through a circular opening 174 in side panel B. Circular openings 107, 108 in each chassis sidewall A and B position the crimped shoulder pins. Additionally, a self-standing post 175 is permanently attached to side panel A through a circular opening 178 in the side panels. Figure 1 、 Figure 2a 、 Figure 2b 、 Figure 3 .

[0259] When side panel A 171 is in the forward position relative to chassis side walls A and B, side panel A rests on top of the crimped lower shoulder pin 113. As long as side panel A remains in this position, the crimped lower shoulder pin prevents rotation of side panel A. While the crimped lower shoulder pin prevents rotation of side panel A, the slotted opening 177 in side panel B constrains the free end of the self-standing post 175 crimped to side panel A, thereby providing mechanical support for the self-standing post and preventing forward movement. This particular configuration of the components comprising the capture frame assembly 170 will be considered the closed or locked position 180 ( Figure 11a ).

[0260] When side panel A 171 is in the rearward position relative to chassis side walls A and B, the bottom edge of the side panel disengages from the crimped lower shoulder pin 113, thereby allowing side panel A to rotate. Simultaneously with the disengagement of side panel A from the crimped shoulder pin, the self-standing post 175 crimped to side panel A also disengages from the slotted opening 177 in side panel B. This particular configuration of the components comprising the capture frame assembly will be considered the locked position 181 ( Figure 11b ).

[0261] In this rearward position, the side panel A, which is movably fastened to the chassis side wall A by means of a crimped central shoulder pin 173, is free to rotate about the crimped pin through a displacement of approximately 180 degrees.

[0262] When the side panel A 171 is rotated 168 approximately 140 degrees from the unlocked position 181, the webbing can be inserted through the gap 114 formed between the two forwardly positioned crimped lower shoulder pins 112, 113, and then through the gap 115 formed between one of the two crimped lower shoulder pins 113, and then positioned around the free-standing post 175 crimped to the side panel A. This particular configuration of the components comprising the capture frame assembly will be considered the unlocked position 182 ( Figure 11c 、 Figure 12c ).

[0263] When side panel A 171 is further rotated 168 to approximately 200 degrees, the enhanced ratchet mechanism can now move in either direction 184 along the length of the webbing configured in this embodiment, with the webbing free to move about the free-standing posts 175 crimped to side panel A. This particular configuration of the components comprising the capture frame assembly will be considered the unrestrained position 183 of the capture frame assembly ( Figure 11d 、 Figure 12d ).

[0264] After the webbing is deployed in the capture frame assembly 170, the following description ( Figure 12c 、 Figure 12d ), the enhanced ratchet mechanism 100 can be activated by moving the capture frame assembly to the locked position 180 ( Figure 12a) is positioned and restrained against the webbing configured in the enhanced ratchet mechanism. This involves pulling side panel A 171 in a direction 188 away from the enhanced ratchet mechanism until the slotted opening 176 in side panel A rests against the crimped center shoulder pin 173, and then rotating side panel A 168 about the crimped center shoulder pin in a direction toward the ratchet end of the enhanced ratchet mechanism. The self-standing post 175 crimped onto side panel A stops the rotation of side panel A when it contacts the extending arm 169 on side panel B 172. At this point, side panel A is then slid toward the front of the enhanced ratchet mechanism, away from the ratchet end of the enhanced ratchet mechanism, until the slot 176 in side panel A is again stopped by the crimped center shoulder pin 173. As side panel A 171 slides to the end 1176 of the slotted opening, the flat strap is locked in place. Simultaneously with this action, the self-standing post 175 pressed onto side panel A will rest against the end of the open slot 177 in side panel B 172. The action of moving the capture frame assembly to the locked position 180 is aided by the arm support 169 extending outwardly from the open slot 177 on side panel B. The arm support acts as a physical stop for the self-standing post 175 pressed onto side panel A 171. This stop limits the rotational travel of side panel A.

[0265] Note that in the locked or near locked position, any subsequent tension introduced into the webbing deployed in the enhanced ratchet mechanism will further cause the capture frame assembly 170 to move onto and / or remain on the hard stops. These hard stops are free-standing posts crimped onto side panel A (side panel A rests on the ends of slots in side panel B) which rest on crimped center shoulder pins. ( Figure 12a 、 Figures 15a to 15f ).

[0266] When the webbing is configured in the enhanced ratchet mechanism and the side panel A is in the locked position 180 ( Figure 12a ) in the case of the enhanced ratchet mechanism along the webbing at arrow 284 ( Figure 13 、 Figure 16g ) is prevented from moving in the direction indicated by the ratchet action. The tension introduced into the webbing by the ratchet action will restrain the capture frame assembly 170 in the locked position, thereby preventing accidental or intentional attempts to move the side panel A to the unlocked 181 position ( Figure 11b 、 Figure 12b The capture frame assembly cannot be moved to the unlocked position 181 or the open position 182 ( ) unless tension is released from the webbing configured in the enhanced ratchet mechanism. Figure 11c 、 Figure 12c Note that in many embodiments, some of which are shown herein, the capture frame assembly 170 can be replaced with alternative structures. Furthermore, the capture frame assembly can be deployed outside the context of a ratchet device in any situation where it is desired to maintain flat belt webbing.

[0267] The joystick 121 is rotatably secured to the chassis sidewalls A and B 101, 102 by two hub crossbars 134 extending through opposing openings 123 in the joystick sidewall 122 and opposing openings 105 in the chassis sidewalls A and B 101, 102. The joystick sidewalls overlap the chassis sidewalls A and B, thereby positioning the two chassis sidewalls inward relative to the joystick sidewall 122. The two hub crossbars 134 also restrain two ratchets 131, each positioned at opposite ends of the hub crossbars by means of two central openings 133 in the ratchet 131. The hub crossbars 134 are positioned separately from each other by a central cross member 138 on the ratchet 131. Each ratchet 131 is positioned inside the joystick sidewall and outside the chassis sidewalls A and B, respectively. Figure 1 、 Figure 2a 、 Figure 2b 、 Figure 3 .

[0268] The lever 121, the two hub crossbars 134, and the two ratchets 131 are secured in position relative to each other and to the chassis sidewalls A and B 101, 102 by means of two washers 196 and two linear locks 197. The washers 196 are positioned at opposite ends of the two hub crossbars 134, abutting the outer surface of each lever sidewall 122. The linear locks 197 are then positioned through transverse openings 135 at each end of the hub crossbars 134 and subsequently deformed to prevent displacement from the hub crossbars. Figure 1 、 Figure 2a 、 Figure 2b 、 Figure 3 .

[0269] The set of two hub beams 134, two ratchets 131, and two linear locks 197, while being held within the confines of the sidewall openings 123 of the lever 121 and the sidewall openings 105 of the chassis sidewalls A and B 101, 102, forms a single unit that is free to rotate in either direction 189 about the long axis of the hub beam 136. The lever 121 can also rotate in either direction 185 about the long axis 136 of the hub beam. Figure 1 、 Figure 2a 、 Figure 2b 、 Figure 3 .

[0270] The joystick handle 129 is permanently affixed to the end of the joystick 121 opposite the end that is fastened to the chassis side walls A and B 101, 102. The joystick pivot pawl bracket 151 is rotatably fastened to the joystick 121 by means of a pivot pin 192 end that is crimped or press fit into a circular opening 125 in each of the joystick side walls 122 and extends through a circular opening 154 in each of the joystick pivot pawl bracket side walls 152. Directly below the joystick pivot pawl bracket is the pad 161. The raised areas 165, 166 on the top surface of the pad 161 are positioned by means of the complementary opening 159 and the edge- along opening 158 in the top surface of the joystick pivot pawl bracket 151. The pad 161 is also constrained by the pivot pin 192 by means of a circular opening 163 in each of the two upstanding supports 162 that are stationed on the bottom side of the pad. The raised areas 165, 166 on the pad 161 (extending through the top surface of the joystick pivot pawl bracket 151) also serve as visual indicators when the joystick pivot pawl bracket is positioned to initiate webbing tension release. A torsion spring 195 is mounted over the pivot pin 192, centered on the pin by the upstanding supports 162 of the pad 161. The legs of the torsion spring press against the bottom side surface of the pad. The pin 193 (permanently affixed to the joystick 121 by means of an opening 124 in each of the two joystick side walls 122) serves as a hard stop for the central portion of the torsion spring 195. The torsion spring brings the teeth details 153 located on each of the joystick pivot pawl bracket side walls 152 into contact with the peripheral edge face 139 on both of the ratchets 131. The pin 193 also serves as a hard stop for the joystick pivot pawl bracket 151, limiting the rotational travel available to the pawl bracket and rotating the joystick pivot pawl bracket into position so that subsequent engagement with the chassis pivot pawl bracket 141 is enabled. This engagement between the two pawl brackets is necessary to initiate tension release of the webbing configured in the enhanced ratchet mechanism 100. The joystick pivot pawl bracket 151 is free to rotate in either direction 186 within the limits dictated by the ratchets 131 and the hard stop provided by the pin 193. Figure 1 、 Figure 2a 、 Figure 2b 、 Figure 3 .

[0271] The chassis pivot pawl bracket pivot pin 191 is positioned below the hub crossbeam 134 by means of a circular opening 103 in each of the chassis side walls A and B 101, 102, ensuring that the necessary force to disengage the chassis pivot pawl bracket 141 from the ratchets 131 under high webbing tension is easily achievable. This provides an important advantage during webbing tension release, making the angular separation between the joystick 121 and the chassis side walls A and B 101, 102 easy to manage. Figures 7a to 10b .

[0272] Finally, when the enhanced ratchet mechanism 100 is in the closed position ( Figure 1 ), a wire or rigid pin 119 of sufficient length may be inserted through the aligned openings 118 in the chassis pivot pawl bracket side wall 142 and the openings 117 in the chassis side walls A and B 101, 102 to prevent the chassis pivot pawl bracket 141 from moving relative to the chassis side walls A and B. This serves as a means of locking the ratchet 131 to prevent inadvertent tension release or unwanted tampering with the ratchet tensioning configuration.

[0273] In many embodiments, chassis sidewall A, chassis sidewall B, joystick, ratchet, side plate A, side plate B, chassis pivot pawl bracket, and joystick pivot pawl bracket are components that can be fabricated from sheet metal, stamped with dies, and subsequently formed using conventional machining practices. Various steel alloys and temperatures can be utilized, depending on cost and performance parameters that determine the dimensions appropriate for any given embodiment. The enhanced ratchet mechanism 100 depicted herein is intended to utilize 1 inch wide webbing material. However, the enhanced ratchet mechanism can be scaled up or down to accommodate other webbing sizes and other load requirements.

[0274] The joystick grip 129, pads, and bottom guard will suitably be made of molded thermoplastic material. For the joystick grip, using tooling to produce an insert mold to encapsulate the end of the joystick will be a viable means of producing a highly durable and cost-effective component. The webbing guide can be manufactured using an inexpensive extrusion tool and cut to length.

[0275] In many embodiments, the two torsion springs 194, 195 are conventionally manufactured components and may be made from tempered music wire or stainless steel wire.

[0276] In many embodiments, the crimped shoulder pins, self-standing posts, crimped end pivot pins, and pin stops can be machined or forged from a variety of steel alloys and temperatures. The intent is to crimp the ends onto each shoulder pin after the various components are assembled. A fixture or tooling fixture can be used to position the components to aid in the crimping operation. Not shown, but readily achievable, is to replace the one-piece crimped shoulder pin with a two-piece arrangement, where a shoulderless straight pin is slid into a secondary hollow sleeve. Various options exist in both material selection and manufacturing techniques.

[0277] Furthermore, the pivot pins 191 and 192 depicted in the enhanced ratchet mechanism can be rolled pins whose ends can be flared after assembly to prevent displacement during field use. This would be suitable for embodiments utilizing lower-cost materials for use under higher webbing tensions. Expanding the ends on the rolled pins can accommodate some degree of hole deformation in the mating components, such as the holes in both the sidewalls of the joystick and the chassis pivot pawl bracket, which are likely to deform under higher loads. This would also be desirable if lower-cost metal alloys were utilized in the construction of the joystick and pivot pawl bracket.

[0278] Operation of the Specific Embodiment

[0279] Figure 6 FIG17. When the lever 121 of the enhanced ratchet mechanism 100 is rotated 185° relative to the chassis sidewalls A and B 101, 102 in a direction that increases the angular separation between the lever and the chassis sidewalls A and B, the lever pivot pawl bracket 151 secured to the lever engages the teeth 132 on each of the two ratchet wheels 131, causing the ratchet wheels and hub crossbar 134 to rotate as a unit within the circular opening 105 in each of the chassis sidewalls A and B. The chassis pivot pawl bracket 141 secured to the chassis sidewalls A and B pivots back and forth following the tooth profile of the rotating ratchet wheels 131. When the direction of lever rotation 185 is reversed, the chassis pivot pawl bracket 141 now engages a single tooth 132 on each of the two ratchet wheels 131, preventing rotation of the ratchet wheels 131 and the hub beam 134, while the lever pivot pawl bracket 151, secured to the lever 121, pivots back and forth, freely following the corresponding edge profiles on the two fixed ratchet wheels 131. Rotation of the lever 121 in the alternating direction 185 results in a ratcheting action in which the two ratchet wheels 131 and the two hub beams 134 rotate in a single direction as a single unit.

[0280] The presence and orientation of a torsion spring 194 attached to the chassis pawl pivot pin 191 and a torsion spring 195 attached to the joystick pawl pivot pin 192 secured to the joystick 121 provide power to bias the tooth detail 153 against the chassis pivot pawl bracket and the tooth detail 143 against the joystick pivot pawl bracket 151 to maintain continuous contact with the edge face 139 along the tooth profile of the ratchet 131. Figure 2a 、 Figure 2b 、 Figure 3 、 Figure 6 .

[0281] like Figures 11a to 16gAs shown, the capture frame assembly 170 is used to removably attach the enhanced ratchet mechanism 100 to any location along the length of the webbing 240 in a secure, fixed position. To attach the enhanced ratchet mechanism 100 to the webbing, the lever 121 is first rotated to the open position, and then the capture frame assembly 170 is moved into the open position 182 ( Figure 2a 、 Figure 11c ).

[0282] A short section of webbing 240 is folded onto itself and inserted into the bottom of the enhanced ratchet mechanism 100 through the gap 114 between two forward-facing, crimped lower shoulder pins 112 and 113. In some contexts, pin 113 is referred to as the first pin, and pin 112 is referred to as the fourth pin. A webbing guide 199 guides the end of the folded webbing upward and then through the second gap 115 between the forward-facing, crimped lower shoulder pin 113 and the crimped center shoulder pin 173. In some contexts herein, gap 115 (also referred to as a hole) may be referred to as the first gap. The user then guides the folded webbing section under the self-standing post 175 crimped to side panel A 171 (now in the open position 182). The end loop formed in the folded webbing section is then positioned around the end of the self-standing post 175. The capture frame assembly (now restraining the end loop of the folded webbing section) is returned to the locked position 180, tightening and positioning the enhanced ratchet mechanism 100 to lock onto the section of webbing 240. Figure 2b 、 Figure 12a -c, Figure 15a -h, Figure 16a -g).

[0283] When the webbing is deployed in the capture frame assembly 170 of the enhanced ratchet mechanism 100, and the capture frame assembly is in the locked position 180, and the upper webbing segment 242 is forced to a greater tension than the lower webbing segment 241, movement along the webbing in the direction indicated by arrow 284 is prevented ( Figure 13 、 Figure 14a 、 Figure 14b 、 Figure 15h 、 Figure 16g ).

[0284] After the enhanced ratchet mechanism 100 is attached to a length of webbing 240, slack in the webbing can be removed by pulling the excess webbing back through the two crimped lower shoulder pins 112, 113. The smooth cylindrical shape of each of the crimped lower shoulder pins protects the webbing from damage when tension in the webbing is increased by the ratcheting action ( Figure 2b ).

[0285] To remove the enhanced ratchet mechanism 100 from the webbing 240, Figures 15a to 15f and Figures 16a to 16gThe attachment process shown in is reversed. In many cases, like at least a portion of those regarding, the tension in the webbing must be released before the enhanced ratchet mechanism can be removed from the webbing ( Figures 18a to 18e ).

[0286] One method of introducing ratchet tension into the strap 251 involves attaching the enhanced ratchet mechanism 100 to the strap via the capture frame assembly 170. One end of the strap (spanning the fixed distance between the two anchor locations) is securely attached to one anchor location 253, and the other end is looped around the second anchor location 254 and back onto the enhanced ratchet mechanism 100. That end of the strap is then restrained and tensioned via the ratchet portion of the enhanced ratchet mechanism 100 ( FIG. 19 ).

[0287] Another method of introducing tension into the strap 252 involves attaching the enhanced ratchet mechanism 100 to the strap via the capture frame assembly 170. One end of the strap is secured to the anchor location 253. A second strap 258, one end of which is attached to the second anchor location 254, is then restrained and tensioned via the ratchet portion of the enhanced ratchet mechanism 100 secured to the first strap 252 ( FIG. 23 ).

[0288] In either approach, the ratchet portion of the enhanced ratchet mechanism 100 is utilized to introduce tension into the strap.

[0289] In order to utilize the ratchet means of the enhanced ratchet mechanism 100, in many cases, the strap may initially be introduced into the ratchet portion of this embodiment. The end of the strap 250 or a folded length of the strap 250 is inserted into the gap 137 (between the two hub beams 134) on the enhanced ratchet mechanism 100. Figure 17a The webbing is then pulled through the gap until all slack is removed from the webbing ( Figure 17b ). Subsequent rotation of the joystick 121 in alternating directions 185 will rotate the hub beam 134 in a single direction, wrapping the webbing around the hub beam ( Figure 17c As the webbing is wound onto the hub beam, the newly wound webbing will cover the underlying webbing layer, thereby securing the webbing to the hub beam. Continue rotating the joystick in alternating directions until the desired tension level is reached ( Figures 17a-17d ).

[0290] A single tooth 143 on each side wall 142 of the chassis pivoting pawl bracket 141 engages a single tooth 132 on each ratchet wheel 131, retaining the tension introduced in the strap and preventing the hub beam 134 and ratchet wheels 131 from rotating in a direction that would release tension from the strap and release the strap from the enhanced ratchet mechanism 100 ( Figure 6 ).

[0291] The ratchet action is similar to that of a prior art ratchet device, i.e., the lever 121 on the ratchet device is rotated in alternating directions 185 to introduce strap tension. Additionally, a single tooth element 143, 153 on the pivoting pawl brackets 141, 151 engages a single tooth 132 located on the periphery of the ratchet wheel 131 in a manner similar to the blade ends on the sliding brackets in prior art ratchet devices ( Figure 6 ). When the lever is rotated, this engagement of the teeth 153 on the lever pivot pawl bracket 151 with the teeth on the ratchet wheel 132 introduces rotation 189 into the hub beam 134 and ratchet wheel 131. The hub beam 134 and ratchet wheel 131 are prevented from rotating in the reverse direction by the teeth 153 on the chassis pivot pawl bracket. Figure 6 , Figure 17.

[0292] The length of the lever 121 provides a mechanical advantage that allows a large amount of tension to be introduced into the strap as the lever is rotated. After the tension-introducing ratchet action is complete, the lever 121 is rotated back to the closed position ( Figure 17d ). The knurling 128 on the side panel B 172 engages with a complementary groove 127 molded into the underside of the lever handle 129 to releasably secure the lever in the closed position ( Figure 2a ).

[0293] By using the pivoting pawl brackets 141, 151, several advantages arise. In terms of component durability and integrity of the tooth engagement, the pivoting pawl brackets 141, 151 provide advantages that are not available with the less advanced sliding brackets of prior art devices. Two of these advantages are minimal component deformation and minimal component misalignment. These advantages arise from the combined synergy of the pivot pins 191, 192, the folds in the pivoting pawl bracket side walls 142, 152, and the close physical proximity of the load bearing components involved ( Figure 6 ).

[0294] The pleats along the sidewalls and along the outward-facing surfaces of the pivoting pawl brackets 141, 151 create stiffness at locations where the highest stresses in the pawl bracket are encountered. Although pleats are sometimes considered a tolerance liability from a manufacturing perspective, the pleats in both pivoting pawl brackets 141, 151 are not located in the tolerance path from the bracket pivot pin locations 103, 124 to the contact area between the pivoting pawl bracket teeth and the ratchet teeth. For both the ratchet 131 and the pivoting pawl brackets 141, 151, the tolerance stack-up comes from the geometry of the punched hole to the punched edge; this is the most economical and easily achievable tolerance control available to the manufacturer. The pleats in the pivoting pawl brackets 141, 151 add strength and stiffness without incurring tolerance liabilities. Furthermore, as the pivoting pawl brackets 141, 151 wear, there is less risk of damaging the tension relief means (which is possible with current technology).

[0295] In prior art devices, either wear on the eccentric end of the lever or the actual cutting induced at the blade end by repeated tension release at or near the rated operating load of the ratchet device eventually limits the travel of the sliding chassis bracket, rendering disengagement of the sliding bracket from the ratchet teeth impossible. In the enhanced ratchet mechanism 100 described herein, wear on either the ratchet teeth or on the chassis pivoting pawl bracket simply causes those components to move closer together before tension release is initiated.

[0296] As previously mentioned, the sliding brackets in prior art ratchet devices can pivot somewhat about their spring restraints, which are typically located a relatively large distance from the engagement interface of the load-bearing blade end. This exacerbates the potential for misalignment and potential damage to the load-bearing blade end on the sliding bracket.

[0297] On the other hand, the pivot pawl brackets 141, 151 are significantly restricted from extraneous movement. The pivot pins 191, 192 are located closely to where the load tooth engagement occurs, thereby greatly reducing any possibility of damage due to misalignment between the load teeth 132, 143, 153 ( Figure 6 ).

[0298] Secondly, the pivot pin 191 securing the chassis pivot pawl bracket 141 to the chassis sidewalls A and B 101, 102 ensures that the contact engagement between the ratchet teeth 132 and each tooth 143 on the opposing sidewall 142 of the chassis pivot pawl bracket 141 occurs simultaneously. Thus, load imbalance is virtually eliminated. This contrasts with prior art ratchet devices, which commonly experience a damaging load imbalance between the ratchet teeth and the end of the sliding bracket blade. This also applies to the lever 121, lever pivot pin 192, and lever pivot pawl bracket 151.

[0299] Finally, lateral movement of the pivoting pawl brackets 141, 151 is constrained between the sidewalls of the lever 122 and the chassis sidewalls A and B 101, 102. The ratchet wheel 131 is fabricated from a thicker material than that used for the pivoting pawl brackets 141, 151. This ensures that the tooth details 143, 153 on each pivoting pawl bracket sidewall 142, 152 will reliably contact the ratchet teeth 132. This arrangement allows for easy accommodation of fold tolerance issues arising from the manufacture of the pivoting pawl brackets 141, 151.

[0300] The ratcheting action employed by the enhanced ratchet mechanism 100 is used to introduce tension into the webbing. The webbing 250, 251, while being confined within the embodiment, is also secured in some manner to or about an anchoring location at a distance from the embodiment. As previously discussed, typical prior art ratchet devices have one of the two straps used in the configuration permanently attached to the device in a fixed end configuration 256. Securing the webbing to an anchoring location, by default, means securing the ratchet device to the same anchoring location. The enhanced ratchet mechanism 100 is not permanently attached to the strap used in the configuration, thereby providing a versatile means for positioning the embodiment on the strap and configuring the length of the strap for subsequent tensioning (Figures 19-29).

[0301] FIG18 shows a series of isometric views depicting the progressive advancement of releasing tension from the webbing 250 configured in the enhanced ratchet mechanism 100. Using the thumb on the thumb edge 164, the lever pivots the pawl bracket 151 ( Figure 3 ), while moving the operating lever 121 toward the open position ( Figure 5 ), causing the tabs 155 and semi-perforated knurlings 156 on the rear end of the joystick pivot pawl bracket 151 to rotate into engagement with the cutouts 147 located on the top surface of the chassis pivot pawl bracket 141. Slightly reversing the direction of rotation of the joystick 121 will fully engage the tabs 155 and semi-perforated knurlings 156 on the joystick pivot pawl bracket 151 with the cutouts 147 on the chassis pivot pawl bracket 141. Releasing the thumb from the joystick pivot pawl bracket 151 allows the spring-biased joystick pivot pawl bracket 151 to seat on the embossed edge 148 on the cutout 147 of the chassis pivot pawl bracket 141. At this point, the two pivot pawl brackets 141, 151 are locked to one another by virtue of the tab-in-slot arrangement ( Figure 7a 、 Figure 7b and Figure 9a 、 Figure 9b ).

[0302] Now, the actual tension release occurs by pulling the lever 121 and the chassis side walls A and B 101, 102 together. With the lever pivot pawl bracket 151 engaged with the chassis pivot pawl bracket 141 as described above, movement of the lever toward the chassis side walls A and B will cause the lever pivot pawl bracket 141 to move the chassis pivot pawl bracket 151 away from the ratchet wheels 131, disengaging the teeth on each chassis pivot pawl bracket side wall 143 from the engaging teeth 132 on each ratchet wheel 131 ( Figure 10a 、 Figure 10b ).

[0303] The lever pivots the pawl bracket 151 to be previously disengaged from the ratchet wheel 131 ( Figure 5 、 Figure 9b ), now that the chassis pivot pawl bracket 141 is disengaged from the ratchet 131, there is no remaining means to prevent the hub beam 134 and the ratchet 131 from rotating ( Figure 10b The tension in the webbing causes the hub beam and ratchet to rotate in a direction opposite to the previous ratchet action, releasing the stored tension from the webbing. The mechanical advantage provided by the geometry of the lever and two pivoting pawl brackets allows hundreds of pounds of introduced webbing tension to be released with only a modest input of force. The entire release action, from start to finish, can be easily performed using a single hand.

[0304] Figure 8a 、 Figure 8b and Figure 10a 、 Figure 10b The key differences between prior art ratchet tensioners (which utilize a sliding bracket for ratcheting and tension release) and the enhanced ratchet mechanism 100 (which utilizes pivoting pawl brackets 141, 151) are revealed. As described elsewhere, releasing tension from a sliding bracket prior art ratchet device can be particularly frustrating. A key factor contributing to this frustration is that the lever in the sliding bracket ratchet device must be opened approximately 170° to perform tension release ( Figure 36 Prior Art During tension release, the lever rotates away from the chassis, rather than toward it. At higher tension levels, if the ratchet mechanism is not physically restrained from engaging the lever to release the introduced webbing tension, the mechanical advantage provided by the lever action in the webbing tension release scheme is compromised. Hence, the aforementioned analogy of the bow and arrow.

[0305] When the webbing tension introduced by the ratchet is released from the enhanced ratchet mechanism 100, the operating lever 121 is moved toward the chassis 101 instead of away from the chassis ( Figure 7a This creates an improved ergonomic arrangement for the user, which is a major advantage compared to current technology arrangements. When releasing webbing tension, the mechanical advantage provided by the lever 121 is virtually eliminated because the lever 121 and chassis side walls A and B 101, 102 are pulled together rather than pushed apart. The forces in the lever and chassis side walls A and B are self-contained, moving towards each other through a small angular displacement rather than away from each other in an unbounded manner ( Figure 18c 、 Figure 18d 、 Figure 18e ).

[0306] In the released state, the hub beam 134 is free to rotate in either direction 189, allowing the webbing deployed in the enhanced ratchet mechanism 100 to be easily withdrawn from the hub beam 134. The area surrounding the hub beam 134 is clear, allowing for easy access when removing the webbing from the enhanced ratchet mechanism 100. Figure 10b 、 Figure 18e .

[0307] Releasing stored energy from a ratchet-tensioned webbing arrangement can be a significant event. The recoil force of the released energy is significant. In current-technology ratchet designs based on sliding brackets, the lever that releases the tension moves in a counterintuitive direction, easily putting the user in danger. Having to push a lever to release hundreds of pounds of stored energy is precarious, to say the least. At the moment of release, the user has little control over the position of the ratchet mechanism. The mechanism actually jumps. Numerous examples of injuries have occurred while attempting to release webbing tension from common current-technology devices. This is particularly true when the user's access to the ratchet mechanism is tightly restricted by the surrounding environment. This situation is greatly exacerbated by the positional constraints imposed by the short webbing segment sewn to the anchor hook.

[0308] In contrast, the enhanced ratchet mechanism 100 releases webbing tension through a small angle of displacement, resulting in a safer and more natural means of moving the lever to the chassis ( Figure 7a 、 Figure 8a ).

[0309] The semi-perforated embossing 156 on the tab 155 of the lever pivot pawl bracket 151 provides additional security during tension release. The semi-perforated embossing will catch the edge of the cutout relief 148 in the chassis pivot pawl bracket, absorbing most of the recoil energy while also preventing the lever pivot pawl bracket 141 from disengaging from the chassis pivot pawl bracket 151 ( Figure 10a 、 Figure 10b ). In addition, the release action described above is self-contained, held by one hand, and limited only by hand movement, with no pushing involved. This allows the user to control the tension release event, rather than the tension release event controlling the user.

[0310] Current ratchet devices utilize a soft metal die-cast lever, which is susceptible to excessive wear at the eccentric end of the lever. Current ratchet devices utilize thin, stamped sheet metal levers, which can easily deform or dig into the end of a blade on the chassis slide bracket, particularly when webbing tension approaches the rated load limit. In these situations, the eccentric end of the lever can be easily affected in its ability to actuate tension release, rendering the device inoperable.

[0311] When webbing tension release is activated in the enhanced ratchet mechanism 100, wear on the pivoting pawl bracket teeth 143, 153 and the ratchet teeth 132 will cause a slight decrease in the separation angle between the lever 121 and the chassis sidewalls A and B 101, 102. This does not affect the embodiment's ability to effect tension release, even at higher tension levels. Therefore, the user-friendly release action will remain reliably effective throughout the life of this embodiment as the components wear. Figures 7a to 10b .

[0312] Figure 5 The enhanced ratchet mechanism 100 is depicted in free rotation. Free rotation allows the joystick 121 to be rotated in either direction 185 without engaging the hub beam 134 and ratchet 131, which would otherwise introduce ratchet tension into the webbing. The first portion of the advancement process in Figure 18 depicts the steps of positioning the enhanced ratchet mechanism 100 in free rotation. Free rotation is achieved by rotating 186 the joystick pivot pawl bracket 151 away from the ratchet 131, disengaging the teeth 153 on the joystick pivot pawl bracket 151 from the teeth 132 on the ratchet 131. Free rotation serves two purposes. The first purpose is to enable the joystick 121 and the joystick pivot pawl bracket 151 to be positioned to initiate webbing tension release (such as Figure 7a and Figure 7b A second purpose is to reposition the lever 121 to a more advantageous position (e.g., Figure 5 This is especially important at higher webbing tension levels.

[0313] Configuration of enhanced ratchet mechanism

[0314] Figures 19 through 29 depict various advancements in configuring webbing and straps using the enhanced ratchet mechanism 100. These figures are self-explanatory and demonstrate the versatility of the enhanced ratchet mechanism 100 in terms of usability.

[0326] Many current ratchet devices (with permanently attached hooks) place the hook close to the device. When anchoring in tight places, operating the ratchet lever can become quite challenging. Of particular importance is the ability to add the enhanced ratchet mechanism 100 to the strap setup after the strap is positioned for use. It is generally easier to work with the strap without having to deal with the size and weight of a permanently attached ratchet device.

[0327] The enhanced ratchet mechanism 100 completely changes the face of ratchet devices. Ratchet devices are specifically designed to introduce high levels of tension into a tightened strap. The single strap fixed end configuration 256 (FIG. 19) enabled by the capture frame assembly 170 effectively doubles the tensioning capacity of the device's ratchet action. Figure 17d This capability alone enables the creation of smaller, lighter ratchet devices that match or exceed the performance of larger, heavier current-technology devices.

[0328] Plus the ratchet mechanism can be easily and adjustably positioned anywhere along the length of the strap ( Figure 12d ), the ability to use straps interchangeably and specifically tailor them to the task at hand, the ability to selectively switch between fixed end 256 or loop 257 configurations, and the ability to securely fasten to any anchoring scenario - all demonstrate the advanced capabilities of the embodiments presented herein.

[0329] Figures 30a to 32b Alternative embodiments are depicted that utilize various means to replicate the functional attributes of the capture frame assembly 170 of the enhanced ratchet mechanism 100 .

[0330] Figure 38a and Figure 38b An alternative embodiment is depicted consisting of a hybrid chassis 435 that incorporates a capture frame assembly 170 that is permanently connected to a current-art ratchet device by means of a short length of webbing sewn into the device. While somewhat awkward, this embodiment does demonstrate that many of the webbing configurations made possible by the new technology can be achieved with the capture frame assembly 170 by modifying the current-art ratchet device accordingly.

[0331] like Figure 33 and Figure 34 The embodiment 380 shown incorporates the capture frame assembly 170 into a cam lock style webbing tensioner. Although not specifically a ratchet device, this embodiment is a tensioner and shows how a typical cam lock device can be improved with the help of a capture frame assembly.

[0332] In some embodiments of the capture frame assembly 170, the device can be used in an alternative configuration without a ratchet, or in a configuration with a more traditional ratchet.The capture frame assembly 170 can be used in a variety of situations.

[0333] While embodiments of the enhanced ratchet mechanism are often deployed in the context of webbing flat straps, the principles and design of the ratchet lever arm and rotating bracket can be deployed in a variety of contexts that do not include flat straps. Furthermore, in some cases, to release tension on the flat straps, it is not necessary to enable the bracket's rotational engagement, and the user may need to push the bracket together or individually to release the flat straps. While this may be less convenient, it can provide a usable alternative.

[0334] Although specific embodiments have been described in detail in the above detailed description, those skilled in the art will appreciate that various modifications and alternatives to these details can be developed based on the overall teachings of the present disclosure and its broad inventive concepts. Therefore, it is to be understood that the scope of the present disclosure is not limited to the specific examples and embodiments disclosed herein, but is intended to cover modifications within the spirit and scope thereof as defined by the appended claims, and any and all equivalents thereof.
