Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of U.S. Provisional Patent Application No. 63 / 516,538, filed on July 31, 2023, the entire disclosure of which is incorporated herein by reference.

[0003] This application is related to U.S. Patent No. 8,997,315, the entire contents of which are incorporated herein by reference. Technical Field

[0004] The embodiments of the present application described herein are devices configured to selectively receive and secure a rope. In some alternative configurations, the device can be used as a pulley before the rope is secured. Background Art

[0005] In many situations, being able to quickly and efficiently attach the end of a rope to an object is advantageous. Typically, the user must tie the rope to the object, which can require knowledge of effective knot tying. In these situations, the user may be unable to apply tension after tying the knot or easily untie it. Furthermore, knots rely on the friction and structure of the rope itself to maintain a secure hold. While highly reliable when tied correctly, knots require proper training and practice to ensure safety, something many users lack.

[0006] Therefore, developed the device for bridging the gap between rope and object, thereby eliminated the device that knot, swaging fitting or other may not provide safe interconnection.Some devices in these devices are intended to make rope remain to be permanently constructed in the device or interconnected with the device, and other devices then allow rope to be selectively removed.The device that is used for rope maintenance also varies because of device design.For example, common boat cleat utilizes tortuous path, and wherein rope is wound around the physical constraint in the device or passes the physical constraint in the device to tighten rope, thereby relies on the friction between the overlapping rope parts and rope is kept in place.Obviously, the knot in this sense is also a kind of tortuous path maintenance scheme.Typical boat cleat is a kind of static device that is permanently attached to anchoring position, and purpose is when using this device at every turn, rope to be tightened is introduced into device and removed from device subsequently.

[0007] Another type of rope cleat relies more on a slightly tortuous path, where the holding device physically deforms the rope. These rope holding devices are often called jam cleats. Like marine cleats, these types of devices are designed to be permanently attached to the anchoring location. This type of device comes in many forms, from ridged wedge-shaped channels to ridged rotating cam wheels that grip the rope as it is pulled through the device.

[0008] Figure 1 A common rope retention device, marketed by Carolina North Mfg. as the Rope Ratchet 8, is shown. This device mechanically clamps a rope between two conical wheels. When the rope is pulled toward the central axis of the rotating wheels, the faceted surfaces of the two opposing wheels engage the rope without contacting it through the camming rims. This device utilizes a ratchet feature to lock the wheels, preventing rotation when the rope is constrained between the opposing wheel faces and under tension, effectively securing the rope. While this type of device can be constructed as part of an initial setup, it is intended to retain the rope in the device during subsequent use. Therefore, the device / rope combination is used to adjust the rope length between anchor points (anchor point 1 is where the device is secured, and anchor point 2 is where an auxiliary hook is anchored, which is secured to the end of the rope extending from the device). As described above, the rope can be introduced into and removed from this type of device. However, this process is often cumbersome, and therefore, optimal utilization of the device occurs when the rope is retained in the device during subsequent use. One consequence of this is that the rope used with the device is often tailored to the device, or vice versa. This means that the components that make up the device are sized to accommodate a specific rope diameter. Furthermore, this type of device utilizes a separate hook (or shackle) that is rotatably secured to the device to serve as a connection to the primary anchoring location. Given the load rating and rope diameter the device is intended to support, the overall size (and number of components) of the device / hook combination can become quite large.

[0009] One advantage of the independently rotatable hooks provided by some existing systems is that the load applied to the rope automatically centers the device / rope / hook along a single axis aligned along the length of the rope under tension. Therefore, a rope retainer coupled to a rotatable hook reduces off-axis loading. Those skilled in the art will understand that off-axis loading generally refers to a situation in which the applied load is misaligned with the intended direction of force transmission. In other words, the load is not applied directly along the axis of the device (ideally, this is the case), but rather at an angle to that axis, which increases friction and wear and reduces efficiency. Furthermore, off-axis loading can pose safety risks, particularly in applications where precise control of load and force is crucial. Unpredictable forces and increased wear can lead to unexpected failures or accidents, particularly in critical applications such as rescue operations or industrial lifting. Off-axis loading is a common weakness in rope retaining devices.

[0010] Figure 2 Another device sold by Nite-Ize, Inc. under the brand name XT12, this device incorporates a rotating cam 14 into a hook and loop anchor attachment 15. Compared to the Rope Ratchet, The XT takes up less space per equivalent load rating. Furthermore, because the cam retainer is integrated with the hook, off-axis loads can be a weak link in this design. Another point worth mentioning is that open-channel bayonet-style rope tie-downs can exacerbate this vulnerability to off-axis loads.

[0011] By nature of their design, the CamJam XT and rope ratchet type devices are intended to be located at one end of a rope configuration, often referred to as a fixed end configuration. In contrast, in devices for ascending a rope, the load-supporting device travels along the rope, rather than attaching the rope end to a specific anchor point. The rock climber / rope ascender 16 is an example of such a rope device (see Figure 3 ). Note that for a rope ascender, the load force binding the device to the rope must be removed before the device can be repositioned along the rope, which is the primary intent of the device design, as it allows the device to be moved in one direction along the length of the rope by alternating the directional load forces applied to the rope. In contrast, the rope ratchet, The XT and similar devices can be used as static pulleys, where a rope is pulled through the device and exits the device in a direction approximately opposite to the direction the rope entered the device.

[0012] By design, ascenders require that the load force in the rope (or more precisely, the load force binding the device to the rope) be removed from the rope before the device can be repositioned along or removed from the rope. The user is typically required to introduce a load force greater than and in the opposite direction of the force binding the rope to the device to begin removing the rope. Both XT-type rope retaining devices offer a way to release the rope tension that binds the rope to the device without first reversing the direction of the tension in the rope. However, the amount of rope tension that a user can release can easily differ by a factor of three or more compared to the device's rated working load limit, making it nearly impossible for the user to release the introduced rope tension, especially when the rope tension approaches the device's working load limit. Therefore, at higher working loads, the user must apply a greater and opposite load force to the rope to release it from the device. At least in theory, a marine rope tie allows the user to release the tension from the rope by simply untangling it from a tortuous rope path. However, if improperly operated, the rope can suddenly release from the marine tie device and cause injury. Furthermore, if the user incorrectly configures the rope in the marine tie device, releasing the rope while it is under tension may require cutting the rope.

[0013] When user interaction, device size, available configurations, and cord selection are considered, other shortcomings that limit the overall effectiveness of current cord tensioning and securing devices arise. Utility Model Content

[0014] One aspect of some embodiments of the present application described herein is to provide an improved rope restraint device that is configured to significantly reduce the occurrence of off-axis, the rope restraint device being configured to accommodate ropes of various sizes and being easy to use. More specifically, one embodiment of the present application includes a hook, shackle, eyelet, or other device adapted to be selectively or permanently interconnected to an anchor that is operatively interconnected to a rope bracket. The rope bracket is configured to receive and support a rope in tension and also accommodate a cam rod that is biased toward a lower interior surface of the bracket. The device adapted to be interconnected to the anchor, bracket, and / or cam rod may employ a hard stop that limits rotation, which helps prevent pinching and off-axis loading.

[0015] During operation, the cam lever rotates away from the lower inner surface, allowing the rope to be admitted. Releasing the cam lever effectively secures the rope within the bracket and prevents movement of the rope in a direction opposite to the insertion direction, i.e., preventing the rope from being pulled out of the rope bracket. In effect, reversing the tension further engages the cam lever with the rope, thereby increasing the tightening force. In this way, the proposed device functions as a one-way pulley. Complete rope release is achieved by rotating the cam lever in a direction opposite to the lower inner surface of the bracket, thereby increasing the space between the cam lever and the lower inner surface and disengaging the cam lever from the rope.

[0016] Thus, the embodiments described herein selectively constrain the rope, thereby avoiding the shortcomings of current rope retention devices. Furthermore, features of the embodiments described herein can be used as pulley-type rope retention devices or rope ascender-type devices. Another benefit is that the devices described herein can be configured to require only intuitive movements. Furthermore, some embodiments benefit from having a proportionally small footprint relative to the rated working load limit, while avoiding off-axis loading and incorporating a tension release capability consistent with the working load limit of the device.

D626393, D934662, D934663, D942840, D943400, D935310, 10584736, D850241, D953147, D1035412, 11629749, D943400, D1024741, 11761473, D1024742, D1026625, and 11920627, which are incorporated herein by reference, may be utilized in some embodiments of the present application described herein.

[0138] Figures 4 to 7cA device 100 for restraining and selectively releasing a rope according to one embodiment of the present application is shown. The device 100 generally includes a hook 104, a rope carrier 108, and a cam lever 112 configured to move relative to the rope carrier 108 to selectively secure / release a captured rope. The hook 104 of one embodiment is constructed of an aluminum die-cast hook 104 that is operably interconnected to the aluminum die-cast cam lever 112, the aluminum die-cast rope carrier 108, and a stainless steel torsion spring 116 by means of a forged metal pivot pin 120. The pivot pin 120 extends through openings 124, 128 in the rope carrier 108, through openings 132, 136 in the cam lever 112, through the coiled torsion spring 116 located in a hook spring cavity 140, and finally through a hook opening 144. Once assembled, the pivot pin 120 is end-swaged, thereby permanently securing the pivot pin 120, the torsion spring 116, the cam lever 112, and the rope bracket 108 to the hook 104. One leg 117a of the torsion spring 116 presses against a recessed surface 118a in the hook 104, and the other leg 117b of the torsion spring presses against a corresponding surface 118b located near the base of a thumb-shaped protrusion 119 in the cam lever 112, thereby biasing the cam lever 112 toward the closed position.

[0139] The cam lever 112 is located within the inner side wall of the rope bracket 108, and the base portion 150 of the hook is located within the inner side wall of the cam lever 112. The cam lever 112 and the rope bracket 108 are free to rotate about the pivot pin 120 along the arrow A. The range of rotation of the cam lever is limited by the following components: cam lever rotation stops 154a to 154d in the cam lever (see, for example, Figure 9b ), corresponding rotation stops 164a-164b in the rope bracket (see, for example, Figure 10c ), and rotation stops 174a to 174f incorporated into the hook member 104 (see, for example, Figure 8c ).

[0140] Some embodiments of the present application utilize a spring door 178 in the form of a stainless steel wire frame that is operatively interconnected to the hook member 104 by means of mounting holes 182, 184 that capture the ends 186, 188 of the spring door. A sliding lock 190 may be provided that slides over the formed spring door 178. The sliding lock 190 may be moved along arrow B toward the base portion of the spring door until the sliding lock 190 engages surfaces 194a, 194b that define a seating portion located adjacent the spring door mounting holes 182, 184. In this configuration, the movement of the spring door is restricted, for example, as Figure 7aAs the sliding lock 190 moves from the bottom of the spring door 178 toward the free end of the spring door 180, the spring door is unlocked and is now free to rotate toward the hook 104 along arrow C. That is, when the sliding lock 190 is located near the bottom of the spring door 178 and contacts the seat in the hook, the spring door is prevented from rotating toward the open position.

[0141] Figures 11a to 11e The cord is shown incorporated into the device 100. Again, arrow A indicates that the cam lever 112 is rotated to allow the cord 200 to be inserted into the opening 204 (see FIG. Figure 5b ) in the direction of the cam rod 112 and the cord bracket 108. The opening 204 in one embodiment is defined by the cord bracket sidewalls 210, 214 and a concave profile 218 defined by an array of gripping geometries 222 protruding from the cam rod 112. After initial insertion, the cord 200 is pulled through the opening 204. The tensioning arrows 215, 216 indicate the opposite direction of tension, which acts to pull the cord further into the device or to withdraw the cord 200. Figure 11c The cord 200 is shown constrained, with the cord 200 aligned with the pivot pin 120 and the center portion 354 of the hook. Figure 11d It shows how the rope is released when the cam lever 112 is rotated in the direction of arrow A.

[0142] In such Figure 11a In the closed position shown with the device empty, torsion spring 116 biases cam lever 112 toward spring gate 178, thereby minimizing opening 204. Hook stops 174d, 174a, 174e, and 174f prevent rotation beyond a predetermined point. When the device is configured as a rope ascender, hook rotation stop 174 also prevents excessive rotation of rope carriage 108 when the rope is subjected to excessive tension. Stabilizing surface 176 on the hook limits rocking motion between rope carriage 108 and cam lever 112 by acting as a physical contact guide toward notch 177 in the rope carriage.

[0143] Pressing the thumb-shaped tab 119 on the cam lever 112 toward the hook 104 in the direction of arrow A rotates the cam lever 112 about the pivot pin 120. Rotating the cam lever 112 will eventually engage the cam lever rotation hard stops 154a, 154b against the corresponding hook hard stops 174c, 174b and fully open the cam lever relative to the rope bracket 108 and maximize the size of the opening 204, as shown. Figure 5b and Figure 11bWith the cam lever 112 rotated to the open position, the rope 200 can be inserted into the hook member gap 358 opening 204. An arrow-shaped protrusion can be provided on the bottom outer surface of the rope bracket 108 to indicate the correct direction for rope insertion.

[0144] Removing a finger or thumb from the thumb-shaped projection 119 on the cam lever 112 allows the torsion spring 105 to relax, thereby rotating the cam lever to a closed position relative to the rope bracket 108, as shown. Figure 7c and Figure 11c At this point, the rope 200 is removably secured because the protruding gripping geometry 222 presses the rope 200 against the inner saddle surface 230 at the base of the rope bracket 108 .

[0145] Tension 215 applied to the end of the restrained cord will tend to pull the cord through the device in the direction of the applied tension. However, cord tension 212 in the opposite direction will interact with the gripping geometry, further rotating the cord cam to a deeper locked position and increasing lateral cord compression, which strengthens the device / cord engagement. In other words, the cam profile 234 of the cam lever 112, in combination with the gripping geometry 222 of the cam lever, will produce increasing pressure on the cord 200 as the cam lever continues to be pulled toward the closed position, which in turn increases the retention force holding the cord 200 within the device 100.

[0146] Figure 9c and Figure 10b The device illustrates how the interaction between the rope cam and the rope carrier is enhanced. More specifically, the cam lever 112 features a tapered portion, with the distal end 320 of the gripping geometry being shorter than the proximal end 324 of the gripping geometry. As the cam lever rotates further into the space defined by the rope carrier sidewalls 210, 214, 328, and 332, the cam lever's coordinated taper mates with the narrowing V-shaped structure of the rope carrier. This coordinated taper allows the device to accept a variety of rope sizes and types. Furthermore, regardless of the rope diameter and type being restrained in the device, full circumferential holding pressure is applied to the rope, distributing the rope-retaining contact force over a larger area of ​​the rope, a characteristic not possible with prior art rope retention devices. This contact force is generated by the cam lever's gripping geometry 133 pressing the rope 200 into the inner saddle surface 230 of the rope carrier 108. The larger area over which the rope holding force (contact force) is distributed minimizes local rope stress and tends to increase the maximum load level that the rope can withstand before failure.

[0147] Although some embodiments of the present application employ a rope retention scheme that produces a similar effect to the jumar-type rope retention device 16 (see Figure 3 ) provides similar retention dynamics, but the rope snare is not designed to accommodate a wide range of rope diameters within a single device, nor is it suitable for use as a static pulley. More specifically, the embodiments described herein can accommodate a wide range of rope diameters and are suitable for use as a static pulley. Furthermore, unlike rope snare-type devices, the specific shape of the protruding gripping geometry 222 arranged on the cam lever 112 minimizes damaging contact interactions with the rope, which enables the rope 200 to be selectively released from the device 100 while the rope is constrained and maintained taut within the device.

[0148] Because the rope carriage 108 can rotate about the pivot pin 120 while being restrained in the hook 104, the tension 216 generated in the rope 200 will create a linear alignment 225 between the tension 216, the pivot pin 120, and the center 354 of the gap 358 defined by the hook, as shown in FIG. Figure 11c The alignment action 350 of the rope tension 216 by rotating the rope bracket 108 enables the device 100 to accommodate a wide range of rope diameters without generating off-axis forces in the rope or the device that could cause premature failure of the hook or rope. Figure 7b ) The ability to rotate through a limited rotational range minimizes the off-axis strains induced on the cord 200 and hook 104 when the cord is subjected to tension 216.

[0149] The cam bar 112 and the rope carriage 108 are also free to rotate around the pivot pin through a specific range of rotation. The range of rotation of the cam bar and the range of rotation of the rope carriage are both controlled by the same hook-shaped member hard stop 174a to 174d. However, the complementary rope cam hard stops 154a to 154d and the rope carriage hard stops 164a to 164d in the cam bar 112 result in different ranges of rotation, which are different for the two components. The presence of the rotation hard stop prevents the rope carriage 108 from rotating with the cam bar 112 through the entire range of rotation available to the cam bar. This difference in range of rotation creates an opening 204 into which the rope 200 is initially inserted when the rope is constructed in the device.

[0150] The primary advantage of this cord insertion method is that a simple single thumb or index finger pressing on thumb-shaped tab 119 causes the cam lever to rotate, which is all that is required to prepare the device 100 for insertion of the cord 200. Furthermore, once the cord is inserted into the device, simply removing the thumb or index finger from the cam lever thumb-shaped tab removably retains the cord within the device. Compared to various prior art cord retention devices, this cord insertion and retention method is arguably one of the simplest.

[0151] Conversely, applying sufficient force to the thumb tab 119 on the cam lever 112 in a direction that rotates the cam lever away from the cord 200, which is held under tension in the device 100, will release the cord. Note that the single thumb or index finger action described above and the tension release action described herein are the same action, thus making user operation of the device very simple.

[0152] like Figure 12 and Figure 13 As shown, the spring door 178 can be rotated to an open position to allow the device 100 to be secured to various types of anchors 300, such as pipes, ropes, wire loops, straps, and the like. Once the device 100 is positioned on an anchor 300 of compatible size, the spring door 178 is rotated back to a closed position, in which the shaped end 180 of the spring door 178 contacts the cutout 304 in the end of the hook, thereby securing the hook 104 to the anchor 300. When the optional sliding lock 190 is moved back to the locked position, accidental release of the device from the anchor is prevented. Moving the sliding lock 190 away from the locked position allows the spring door 178 to be rotated to an open position, thereby allowing the device to be removed from the anchor to which it is secured. Excessive rope tension that may result from unintentional load shifting may be released from the device using an auxiliary tool 308 that is positioned into a recess 312 on the underside of the thumb tab 119 of the cam lever 112 to impart a knocking action to the rope cam.

[0153] Figure 14 Shown Figure 4 100 in an adjustable, fixed-length configuration. Note that the elastic cord or string 400 can be permanently confined within the device 100, yet still freely move through the device in an adjustable manner. Slide 404 and end cap 408 are used to arrange and organize the elastic cord or string. End cap 408 also serves to secure the elastic cord or string 400 within the loop that permanently bonds the device 100 to the elastic cord or string 400.

[0154] Figure 15Two devices 100 are shown attached along a portion of a line 500, which is securely held at a fixed anchoring location 504. Each device 100 is held adjustable in position along the line 500. The locking feature of the device 100 prevents movement in one direction along the line while allowing movement in another direction. Various combinations utilizing multiple units of the device 100 can be formed. For example, Figure 15 As shown, two embodiments are placed opposite each other, with the flexible marker portion 508 suspended from a fixed line while being held taut. Another example is to add multiple units of the device 100 along a single line to use as a fish stringer, where the hook-shaped portion of the small device will hook the gills of a fish. When a subsequent fish is caught, additional copies of the device can be removably added to the line that is now securing the previously caught fish.

[0155] Figure 16a and Figure 16b A device 600 is shown that incorporates a hookless eye loop 602 into the device, rather than using a gate hook. Several different uses of this embodiment are envisioned, such as standalone use or paired with other components.

[0156] Figure 17a and Figure 17b The device 600 is shown paired with a common style carabiner 700. Functionally, the combination of the device 600 and the carabiner 700 is equivalent to Figure 4 In addition, the device 600 can be easily removed from the shackle, thereby returning the shackle to its original state. A significant advantage of this embodiment is that a variety of commercially available shackles are compatible with the device and these shackles can be used alternately in their original state or quickly converted into a rope tightening device.

[0157] Figure 18 The device is shown permanently attached to the anchoring location by means of a closed loop 704 fastened to the anchor 300, while Figure 19 The device is shown removably secured to the anchor 300 location by means of an open ring 708 secured to the anchor.

[0158] Figure 20a and Figure 20b The following device is shown: this device combines a permanently attached, sewn webbing fabric loop 712 with the above-described device 600. One advantage of this embodiment is that it can easily accommodate large diameter or irregularly shaped anchoring locations. In addition, this embodiment highlights the advantages of aligning the tension load 216 in the rope 200, the rope bracket, the cam rod, and the hookless eye 602 to a fixed anchoring location to minimize off-axis stress in the system.

[0159] While some of the components described herein are constructed from die-cast aluminum, various other materials and manufacturing methods may be used to produce these components without departing from the scope of the present invention. One example is the use of glass-filled thermoplastics molded to produce the hook, cam lever, and / or cord bracket, where such materials are economically and structurally compatible with the use of elastic cords.
