Description

Retrieval device for retrieving a rope using a mechanical engagement, receiving device and method of using the same

Technical Field

Various embodiments relate to: a retrieval device for retrieving a line having one end portion connected to the receiving device; a receiving device for receiving the recovery device for recovering the rope; and a method of retracting the rope.

Background

In many sports-related activities, particularly in the adventure sports industry, ropes or cords may be used. It is an important aspect to implement the retraction of the rope in a safe and efficient manner.

One particular adventure sport of interest is the bungee jump, which may also be referred to as high-altitude bounce.

In a bungee jump, a person jumps off a tall structure (e.g., a bridge, building, etc.), and the person (the jumper) is connected to the structure by a large, resilient cord. The rope may be referred to as a bungee cord or bungee cord. When a person (a jumper) jumps, the rope extends downward toward the ground. Due to the elasticity of the rope, the rope stretches to its maximum, after which the skipper can fly upwards when the rope bounces back, and continues to oscillate (bounce up and down) until the kinetic energy in the rope is substantially dissipated. Commercial operation of the bungee jumping sport has existed for nearly 30 years.

A bungee jump can be considered complete when the jumper (still connected to the bungee cord) stops oscillating (bouncing up and down) for more than a few meters.

Once the bungee jump is complete, the bungee jump retrieval system may be activated to retrieve the cord. This process may be referred to as "bungee bounce recovery" or "high altitude bounce recovery".

Bungee jump recovery may also mean that the jumper is recovered by it after completion of the bungee jump. There may be two ways to recover a skipper, either by raising to the original skip position, or by lowering to an area below the original skip position.

The elevated bungee jump retrieval system may involve the use of a rope attached to a winch (winch) to raise the jumper back to the original jump position. The simplest way may be to lower the rope to the skipper who attaches the rope to itself and then pull the rope up by a winch, raising the rope back to the original skipping position.

Typically, an indication of the recovery of a bungee jump may be communicated to the jumper prior to the start of the bungee jump. Hand signals and verbal communication may also be used during and/or after jumping. However, in stressful situations (e.g. after a bungee jump), the jumper sometimes forgets the indication given earlier. In some extreme cases, the skipper may be immobilized due to the fear generated during the skipping. There may also be situations where the jumper may be injured, or may lose consciousness and be unable to perform the indication.

Therefore, there is a need for an apparatus for retrieving or recovering a line to eliminate or at least minimize reliance on a jumper to properly and safely connect a retrieval or recovery device or retrieval line to the jumper when the bungee jump is complete. Further, the amount of time required to retrieve the rope and the skipper may be reduced, thereby increasing profitability, particularly on busy days when the number of skipper increases.

Fig. 1A shows a cross-sectional schematic view of a retrieval device 100 for retrieving a cord 110, the cord 110 having one end portion connected to a receiving device 120, according to various embodiments. For example, the retrieval device 100 may be used to retrieve the cord 110 with the receiving device 120 attached to one end portion of the cord 110. The retrieval device 100 includes a connection assembly 102 having an opening 104 configured to receive a portion of the cord 110 for moving the connection assembly 102 (or, effectively, the retrieval device 100) along the cord 110, as indicated by the dashed line 112. At least a portion of the connection assembly 102 is adapted to mechanically connect to at least a portion of the receiving device 120, as indicated by dashed line 112 through dashed line 114. The linkage assembly 102 includes a retraction member 106 configured to facilitate movement of the linkage assembly 102 in a direction toward an opposite end portion of the cable 110. The opening 104 may be disposed adjacent the retraction member as shown by line 108. The connection assembly 102 also includes at least one hook member or body 105 configured to mechanically connect with the receiving device 120. The connection assembly 102 includes at least one non-ferromagnetic hook. Each hook body includes a shank and a curved member extending therefrom. The shank includes a ferromagnetic shank portion. A gap is provided between the shank portion and the flexure member. The handle portion is configured to magnetically connect with the guide of the receiving device 120. Because the guide is connected to the loop of the receiving device 120, the magnetic connection is configured to move the loop to the engageable configuration. The flexure is configured to mechanically engage with the loop to bring the loop from an engageable configuration to an engaged configuration. The aforementioned mechanical engagement is configured to magnetically disengage the guide from the handle portion.

In the context of various embodiments, the term "retract" may also refer to retrieve, pull, winch, pull, or raise.

The term "connected" also means coupled, in contact with, attached to, or secured to … ….

The term "opening" may refer to a cavity, hole, or gap.

The phrase "receiving a portion of a cord" may refer to surrounding or enclosing a portion of the cord 110 within the opening 104. For example, the opening 104 may include a through-hole along the axial center of the connection assembly 102, and the received portion of the cord 110 may be free from contact with at least a portion of the wall of the through-hole. The cable 110 may extend in a direction substantially parallel to the axial center of the connection assembly 102. In this manner, the linkage assembly 102 may move along the rope 110 with zero or minimal resistance to each other, thereby preserving the integrity of the rope 110.

For example, movement of the linkage assembly 102 along the cable 110 may mean the linkage assembly 102 sliding along the cable 110.

In the context of various embodiments, the phrase "one end portion of a cord" may refer to the distal end portion of the cord 110. An end portion of the cord 110 may mean an end (or tip) of the cord 110 or any portion immediately adjacent to an end of the cord 110.

In the context of various embodiments, the term "non-ferromagnetic" may refer to the absence of magnetic permeability or the presence of low magnetic permeability, while the term "ferromagnetic" may refer to high magnetic permeability. The phrase "hook" may refer to a frame structure constructed and arranged to mechanically engage another structure or element. The term "flexure" may refer to a distal portion and/or a proximal portion of the hook shaped to mechanically engage another structure or element. The term "handle" may refer to a portion of the hook body other than the flexure. The phrase "handle portion" may refer to a portion of the handle. The phrase "extending therefrom" may mean that the handle is integrally formed with the flexure, or that the handle is directly or indirectly connected to the flexure. The term "gap" may refer to an opening, a spacing, or a separation.

In the context of various embodiments, the phrase "magnetically connected" may refer to a magnetic coupling or connection or magnetically attached or magnetically secured. For example, "magnetically connected" may mean that the magnetic force may be between a permanent magnet and a ferromagnetic element, or between a permanent magnet and another permanent magnet. The phrase "magnetically decoupled" may refer to magnetic decoupling or magnetic disconnection or magnetic separation. For example, "magnetically separated" may mean that there may be a lack or insufficient magnetic force between a permanent magnet and a ferromagnetic element, or between a permanent magnet and another permanent magnet, such that there is no attachment or maintained contact between the two.

In the context of various embodiments, the phrase "loop" may refer to a generally circular, oval, or teardrop shape that is part of or formed by all of the support band. The phrase "guide" may refer to any element configured to drive or move a ring into an engageable configuration.

In the context of various embodiments, the phrase "mechanically engaged" may refer to attachment or securement by physical connection or mating of two or more structures or elements. The phrase "engageable configuration" may refer to an arrangement of loops wherein the loops have not yet received a flexure therein but are sufficiently extended to receive a flexure therein. The phrase "engaged configuration" may refer to an arrangement of loops in which the loops have received a flexure therein and in contact therewith, and may also refer to an arrangement of loops in which the loops physically interlock with the received flexure such that the interlock is sufficiently secured to allow the receiving device to be raised.

In the context of various embodiments, the phrase "opposite end portions of the cord" may refer to end portions of the cord 110 that extend away from the distal end portions of the cord 110, or may be the distal end portions of the distal most cord 110 relative to the distal end portions of the cord 110. The opposite end portions of the cord 110 may mean the opposite ends (or tips) of the cord 110 or any portion immediately adjacent to the opposite ends of the cord 110. For example, if the opposite end portions of the cord 110 are maintained at a height away from the ground and the cord 110 is allowed to freely extend in a downward or vertical direction toward the ground, the distal end portions of the cord 110 may refer to the bottom end portions of the cord 110 and the opposite end portions of the cord 110 may refer to the top end portions of the cord 110.

In the context of various embodiments, the term "toward an end portion of a cord" may mean "substantially near an end point of the cord. The term "toward the opposite end portion of the cord" may mean substantially near an end point of the cord 110 extending away from the distal end portion of the cord 110, or substantially near an end point of the cord 110 that may be the farthest with respect to the distal end portion of the cord 110.

In the context of various embodiments, the phrase "facilitating movement of the connection assembly in a direction toward the opposite end portion of the rope" may refer to causing or allowing the connection assembly 102 to move to a position that is in substantially the same plane as the opposite end portion of the rope 110. For example, if the opposite end portions of the cord 110 are maintained at a height away from the ground and the cord 110 is allowed to extend freely in a downward or vertical direction toward the ground, the plane of the opposite end portions of the cord 110 may be substantially parallel to the ground. In this case, the phrase "facilitating movement of the connection assembly in a direction toward the opposite end portion of the rope" may refer to the connection assembly 102 moving upwardly away from the ground to a position substantially at or near the height of the opposite end portion of the rope 110, which position is also referred to as the home (jump) position or start position. The home (jump) position or starting position may also be a retrieval position, which may be a home (jump) position or starting position in close proximity to a height generally at or near the opposite end portion of the cord 110.

In other words, various embodiments may relate to a recovery device 100 for retrieving a rope 110, such as a bungee cord or bungee cord. The receiving device 120 may be attached to one end portion of the rope 110. For example, the retrieval device 100 may be positioned around the portion of the cord 110 at the opposite end portion of the cord 110 after the cord 110 has been extended from the opposite end portion of the cord 110. The retrieval device 100 may be moved or may be lowered to the receiving device 120 and may be guided through the magnetic connection to mechanically connect to the receiving device 120, thereby releasing the magnetic connection. When the recovery device 100 and the receiving device 120 are mechanically connected to each other, the retrieval member 106 may be used to move or lift the recovery device 100 and the receiving device 120 together back to a position at or substantially near the opposite end portions of the rope 110, which is the recovery position. The raising of the retrieval device 100 includes mechanical coupling of the receiving device and does not include magnetic coupling therebetween. By doing so, the rope retraction process can be carried out automatically, without intervention by the jumper. In addition, since the magnetic coupling is only used for alignment of the rings and is not used during the ascent of the jumper, the materials (in particular ferromagnetic elements) used for the recovery device 100 and the receiving device 120 can be much smaller and lighter than the devices used for the magnetic coupling employed during the ascent of the jumper. This reduces the weight of the jumper's end, thus improving the overall safety of the bungee jump and cord retrieval.

In various embodiments, the connection assembly 102 may further include a first member and a second member connectable to the first member, wherein the first and second members are configured to move relative to each other between a closed configuration and an open configuration, wherein in the closed configuration, the first and second members are configured to move toward each other to form the opening 104 to receive a portion of the cord 110; wherein in the open configuration, the first and second members are disposed to move away from each other to receive or release a portion of the cord 110. The first member and/or the second member may be connected to at least one hook.

In other words, in a closed configuration, opening 104 may form a closed loop, and in an open configuration, opening 104 may form an open loop, wherein the first and second members may be arranged to move away from each other to provide an entrance/exit to receive or release a portion of tether 110.

In one embodiment, the first member may be fixed and the second member may be movable relative to the first member.

In another embodiment, the second member may be fixed and the first member may move relative to the second member.

In another embodiment, both the first member and the second member are movable relative to each other.

In the context of various embodiments, the term "contain" may mean surround or enclose.

In various embodiments, the first member and/or the second member may be passed through at least one hook, for example, through an opening of the hook.

In one embodiment, the first member and/or the second member is welded to the at least one hook.

In various embodiments, the first member and/or the second member are integrally formed with the at least one hook body.

In various embodiments, the first member may be arranged to pivot relative to the second member.

In other words, the first member may be moved relative to the second member by the pivot point. For example, the pivot point may be a hinge. In this embodiment, the connection assembly 102 may function similar to a clamp, while the first and second members may function similar to arms of a clamp.

In various embodiments, the connection assembly 102 may function similar to an open-ended enclosure having an overlapping pendulum (overlapping flap) or snap-back flap, wherein the first member may be a pendulum and the second member may be an open-ended enclosure. For example, the first member and the second member may be different sizes, and the connection assembly 102 may function similar to a hook and loop (carabiner).

In another embodiment, the connection assembly 102 may function similar to an open-ended enclosure with a removable cover or door, where the first member may be a removable cover or door and the second member may be an open-ended enclosure.

It may be useful to have the first member and the second member arranged to move relative to each other, for example during a bungee jump. This may be due to the manner in which the bungee cord (e.g., 110) is manipulated and the manner in which the layout of the bungee platform is set. In these cases, there may simply not be enough space around where the bungee cord 110 may be attached to the platform (in the original jump position) to allow attachment prior to the bungee. In other words, there may be no way to have the recovery device 100 surround the bungee cord 110 after a jumper has jumped off the platform, other than to make the first and second members of the recovery device 100 openable.

In other embodiments, the retrieval device 100 may include a third member or more members to form a closed loop in the closed configuration. While it is possible to divide a circle into more than two portions (a first member and a second member), such a design may require more complex portions.

In various embodiments, the first member and the second member may be further configured to be releasably secured to one another.

In various embodiments, the connection assembly 102 may further include a locking mechanism to releasably secure the first and second members in the closed configuration. For example, the locking mechanism may include a locking pin.

In the context of various embodiments, the term "locking" may be interchangeably referred to as securing, bolting, or latching.

In various embodiments, the combination of the shank portion and the shank may be configured to provide a taper toward the flexure member.

In the context of various embodiments, the term "taper" may refer to a narrowing, thinning, or reduction in cross-sectional area. The phrase "taper toward the tip" may refer to a narrower, thinner, or reduced cross-sectional area near the tip as compared to portions away from the tip.

For example, the cross-section of the shank portion proximal to the flexure is smaller than the cross-section of the shank portion distal to the flexure.

In various embodiments, the combination of the shank portion and the shank may be substantially uniform or non-tapered.

In various embodiments, the shank portion and/or the guide comprise a permanent magnet.

For example, the shank portion contains a permanent magnet and the guide contains a ferromagnetic element, or vice versa.

For example, the shank portion and the guide each contain a permanent magnet.

For example, the permanent magnet may comprise a neodymium magnet.

In various embodiments, the first member and/or the second member may comprise a metal body.

Other suitable materials may be used with the purpose of allowing the integrity of the cord 110 (e.g., the rubber of the bungee cord) to be protected and retained from rubbing against any portion of the connection assembly 102 that may damage the cord 110. Each metal body may include a light and structurally strong material so that the weight of the receiving end 120 may be minimized. This in turn may minimize the negative impact on the impact of a jumper at the receiving end 120.

The first and second members in the closed configuration may form a circular or annular shape, or other shape, in various embodiments.

In various embodiments, a retraction member 106 may be connected to each hook.

For example, the retraction member 106 may be indirectly connected to each hook, such as by a connector, strap, or cord.

In various embodiments, the retraction member 106 may be integrally formed with or directly connected to each hook.

In various embodiments, retraction member 106 may include an eyelet (eyelet) configured to receive a retraction cord.

For example, the retrieval string may be attached or connected or tied to the eyelet. The retrieval line may be referred to as a retrieval line or a winch line.

In the context of various embodiments, the term "eyelet" may be interchangeably referred to as an eyebolt (eyebolt) or ring, which may be circular, oval, or generally polygonal (e.g., triangular, square, rectangular), or other unconventional shape.

In various embodiments, at least one hook comprises a plurality of hooks, each hook being disposed at a substantially equal distance from an adjacent or neighboring one of the hooks.

In the context of various embodiments, the term "distance" may refer to the circumferential distance formed by the first member and the second member.

In various embodiments, central component 122 includes a cushion component that surrounds at least a portion of the central component and at least a portion of cord 110. The pad component is optional, but may be advantageous in that it provides a covering or covering for protecting the skipper from injury due to impact with the receiving device 120 and for protecting the central component from wear.

For example, the pad component 124 may include first, second, and third pad sections. The first liner portion may be provided as a top sleeve. The diameter of the opening 104 of the first liner section may be suitably sized to allow the cord 110 to pass therethrough. The diameter of the first liner section may be suitably sized to be received within the opening of the recovery device 100. The diameter of the second pad section may suitably be sized to allow the hooks to fall thereon and/or prevent the hooks from moving further toward the jumper when the first pad section is received in the opening 104 of the recovery device 102. The height of the second pad section may be configured to bring the stem section into proximity with the guide when the hook body falls on or contacts the second pad section. The third pad may receive a portion of the central member and provide at least one opening for receiving at least one support band therethrough, the support band configured to be coupled to a jumper.

In an embodiment, the first, second and third pad sections may be integrally formed.

In various embodiments, the guide may be a non-rotatable element.

In various embodiments, the guide comprises a permanent magnet, such as a neodymium magnet.

In some embodiments, the guide and the shank portion may comprise the same material, such as a permanent magnet. In other embodiments, the guide and the shank portion may comprise different materials, such as permanent and non-permanent magnets, respectively, or vice versa.

In various embodiments, the receiving device 120 can be used to receive the retrieval device 100 moving from the opposite end portion of the cord 110 toward the receiving device 120 at one end portion of the cord 110.

The phrase "opposite end portions of the cord" may be described in a similar context to the above.

Fig. 1C shows a cross-sectional schematic view of a device 140 for retracting a rope (e.g., 110) according to various embodiments. The device 140 may comprise a recovery device 100 according to various embodiments and a receiving device 120 according to various embodiments. As shown by line 142, the recovery device 100 and the receiving device 120 may be mechanically connectable to each other so as to cooperate with each other.

In other words, a method for retrieving a cord having one end portion and an opposite end portion may be provided. In fig. 1D, at 162, a retrieval device (e.g., 100) is movably connected to an opposite end portion of the cord 110. At 164, the recovery device 100 is moved to a receiving device (e.g., 120) at one end portion of the rope 110, and the recovery device 100 is magnetically connected with the receiving device 120. At 166, the recovery device is mechanically engaged with the receiving device. The mechanical engagement results in a magnetic separation of the recovery device from the receiving device. At 168, a pulling force is applied to a retrieval string connected to the retrieval device 100 to retrieve the retrieval device 100 and the retrieval device 120 together toward opposite end portions of the string 110.

The recovery device 100 and the receiving device 120 may comprise or may relate to the same or similar elements or components as the recovery device 100 and the receiving device 120 of fig. 1A and 1B, respectively, and therefore, the same numerals are assigned, and similar elements may be as described in the context of the recovery device 100 and the receiving device 120 of fig. 1A and 1B, respectively, and thus, corresponding descriptions may be omitted herein.

In the context of various embodiments, the term "retrieval" and the phrases "magnetically coupled," "magnetically decoupled," "mechanically engaged," "one end portion of a cord," "an opposite end portion of a cord," "toward an opposite end portion of a cord" may be described in a similar context to the above.

The term "movably connected" may mean attached (or attachable) and may move along. In other words, for example, the recovery device 100 with a recovery cord may be placed on opposite end portions of the cord 110 and be (able to be) movable along the cord 110.

The term "moving" with respect to the recovery device 100 may also mean being lowered.

The phrase "magnetically connecting the retrieval device with the receiving device" may also mean that the retrieval device 100 and the receiving device 120 may be magnetically connected, fixed, or attached to each other. The phrase "mechanically engaging the recovery device with the receiving device" may also mean that the corresponding elements of the recovery device 100 and the receiving device 120 may be connected or fixed to each other. The phrase "mechanically engaging magnetically separates the retrieval device from the receiving device" may also mean that the retrieval device 100 and the receiving device 120 may be magnetically separated, unsecured, disengaged from each other during the causing and/or mechanically engaging process.

The phrase "applying tension on the retrieval string" may also mean applying tension on the retrieval string, or raising the retrieval string.

In various embodiments, the step of magnetically coupling 164 the recovery device 100 to the receiving device 120 includes: the handle portion is magnetically coupled to the guide, the magnetic coupling moving the loop to the engageable configuration.

In various embodiments, the step of mechanically engaging the recovery device 100 with the receiving device 120 (the mechanical engagement causing the magnetic separation of the recovery device 100 from the receiving device 120) at 166 comprises: the flexure is mechanically engaged with the loop, the mechanical engagement causing the loop to change from an engageable configuration to an engaged configuration, the engaged configuration pulling the guide away from the shank portion to magnetically separate the guide and the shank portion.

In various embodiments, the retrieval string may be coupled to the retrieval member 106 of the retrieval device 100 prior to removably coupling the retrieval device 100 to the opposite end portion of the cord 110.

In various embodiments, removably attaching the retrieval device 100 to the opposite end portion of the cord 110 may include receiving a portion of the cord 110 within the opening 104 of the attachment assembly 102 of the retrieval device 100.

In various embodiments, the method 160 may further include guiding the connection assembly 102 along the rope 110.

While the above-described method is illustrated and described as a series of steps or events, it should be appreciated that any sequence of such steps or events is not to be interpreted in a limiting sense. For example, some steps may occur in different orders and/or concurrently with other steps or events apart from those illustrated and/or described herein. Moreover, not all illustrated steps may be required to implement a described aspect or embodiment of the invention. As such, one or more steps described herein may be implemented in one or more separate acts and/or phases.

An example of the method of retracting the cord (e.g., 110), such as a bungee cord, according to various embodiments will be described below.

Fig. 2A shows a diagram 200 illustrating an example of a snapshot of a process of a bungee jump, while fig. 2B and 2C show diagrams 220, 240 illustrating examples of subsequent rope retrieval process snapshots according to various embodiments.

The recovery device and the receiving device may include or may refer to the same or similar elements or components as the recovery device 100 and the receiving device 120 of fig. 1A and 1B, respectively, and therefore, the same numerals are assigned, and similar elements may be described in the context of the recovery device 100 and the receiving device 120 of fig. 1A and 1B, respectively, and thus, corresponding descriptions may be omitted herein.

During a bungee jump, the receiving device 120 may first be connected or attached to the jumper 202 at one end 204 (or one end portion) of the cord 110. Receiving device 120 may be placed on the foot of jumper 202. Skipper 202 may be positioned at platform 206 at a starting location (or may also be referred to as a home (jump) location). Opposite end 208 (opposite end portion) of cord 110 may be secured to a lower surface of platform 206 relative to an upper surface of platform 206, on which jumper 202 may be placed in a starting position, or secured to other suitable portions of platform 206.

As shown in the diagram 200 of fig. 2A, the receiving device 120 may be referred to as a "jumper. The "jumper end" may be secured to an end (e.g., 204) of the bungee cord 110.

At instance (i), a jumper 202 may jump or move off of the platform 206 to perform a bungee jump. In example (ii), the rope 110 may extend away from the platform 206 and towards the ground. The ground may be land or water. In example (iii), a bungee jump may be considered complete when the cord 110 is fully extended and generally in equilibrium (where the jumper 202 has stopped bouncing and is ready to be recovered, or where the cord 110 has only swung a few meters (e.g., about 1 m or less in up and down motion)).

One end 210 of a retrieval string 212 (e.g., a winch string) may be connected to the retrieval component 106 of the retrieval device 100. The other (opposite) end 214 of the retraction cord 212 may be attached to a winch 216 or pulley system to facilitate cord retraction.

Fig. 2B shows a diagram 220 illustrating an example snapshot of the bringing or lowering of retraction cord 212 to jumper 202. As shown in example (iv), when the bungee jump is complete, the recovery device 100 can be placed on the opposite end 208 (or opposite end portion) of the cord 110 such that a portion of the cord 110 is received within the opening 104 of the connection assembly 102 of the recovery device 100, such as by the bungee operator 222. The recycling apparatus 100 may also be referred to as a "recycling end". In example (iv), the "retrieval end" may be opened and then secured around the bungee cord 110.

Recovery device 100 may be lowered toward receiving device 120, which is attached to one end 204 (or one end portion) of cord 110 at the foot of jumper 202. In other words, in example (v), the "retrieval end" may be lowered by the winch rope 212 the entire length of the bungee cord 110.

Upon reaching one end 204 (or one end portion) of the cord 110, the retrieval device 100 and the receiving device 120 may be guided through a magnetic connection so as to be secured to each other by a mechanical connection upon which the magnetic connection is released. That is, the "recovery side" may be connected with the "jumper side" as in the example (vi).

Fig. 2C shows a diagram 240 illustrating an example snapshot of retraction cord 212 retracted with jumper 202. The retrieval string 212 may then be pulled or raised upwardly toward a retrieval position, which may be near or at the starting position of the platform 206. In examples (vii) and (viii), capstan 216 may pull skipper 202 back up to the original (skip) location/position via capstan rope 212. At the retrieval position (instance (ix)), the retrieval device 100 may be removed from the rope 110, and the jumper 202 may be released from the receiving device 120 and the rope 110, e.g., with the assistance of a bungee operator 222; allowing the rope 110 to be retracted and attached to the next skipper at the starting position.

It will be appreciated that when the recovery device 100 is mechanically connected to the receiving device 120 having a line 110 extending towards the ground, the lifting force between the recovery device 100 and the receiving device 120 may be effective in a direction along the pull-up direction in which the line 110 extends.

In the retrieval position (e.g., example (ix)), the retrieval device 100 may be removed from the receiving device 120 by mechanically disengaging (i.e., thereby releasing) the at least one hook from the at least one loop; releasing or separating the first member from the second member, both forming an opening of the connection assembly; and separates the recovery device 100 from the rope 110. This may allow the recycling device 100 to be easily removed from the receiving device 120.

In general, before a bungee jump is initiated, a "jumper end" or receiving device 120 may be attached to the same end 204 (or the same end portion) of the bungee cord 110 as the bungee jumper 202. After the bungee jump is completed, a "retrieval end" may be attached to the bungee cord 110. Using the winch 216, the "recovery end" may be lowered the full length of the rope 110 to be secured to the "jumper end". Once secured or connected, the bungee jumper 202 can be raised back to the original jump position or other post-recovery position adjacent to the original jump position by the winch 216.

An example of a retrieval device (e.g., 100) for retrieving a rope (e.g., 110) (e.g., a bungee rope) at a "retrieval end" in accordance with various embodiments will be described below.

According to one embodiment, fig. 3A illustrates a top view 300 of an exemplary recycling apparatus (e.g., 100), while fig. 3B illustrates a bottom view 301 of the exemplary recycling apparatus.

The recovery device 302 may include or may refer to the same or similar elements or components as the recovery device 100 of fig. 1A, and therefore, similar elements may be described in the context of the recovery device 100 of fig. 1A, and thus, corresponding descriptions may be omitted herein.

As shown in fig. 3A and 3B, the retrieval device (or "retrieval end") 302 may be comprised of a loop 340 for providing the opening 104, a plurality of hooks 360 (e.g., 4), a plurality of connectors 322 (e.g., 4), and an eyelet 324.

The ring body 340 may include or consist of two pairs of half rings 342 (see fig. 3C) that overlap and fit together to form a complete ring. The half ring 342 may be hinged (via hinge 308) on one side, allowing the ring body 340 to be opened and closed. The opposite side may provide a locking pin 310 to prevent accidental opening. After completing the bungee jump, the ring 340 can be opened, slid over the bungee cord (e.g., 110) and lowered along the cord 110 to the jumper (e.g., 202). Each pair of half rings 342 may comprise two overlapping and/or interleaved portions. The half rings 342 may comprise a non-ferromagnetic metallic material, such as an aluminum alloy, or an aluminum alloy impregnated with magnesium.

Once recovery of the bungee jumper is complete, the locking pins 310 may be unlocked and the "recovery end" 302 may be removed from the bungee cord. The ring 340 can provide a framework to anchor other components and can protect the bungee cord 110 from damage.

Each hook 360 (see fig. 3D) may include a curved piece 362, a stem 364, and a plurality of openings 366, 368. The curved piece 362 forms an end portion of the hook body 360 and is configured to mechanically engage with a loop of a receiving device. A shank 364 extends from the flexure 362 and is disposed or oriented relative to the flexure 362 such that a gap 363 is provided between a portion of the shank (alternatively referred to as shank portion 365) and the flexure 362. The gap 363 is configured to receive the ring during engagement of the machine. The shank portion 365 includes a ferromagnetic element, such as a high performance magnet, while the remainder of the hook body 360 and the flexure 362 include a non-ferromagnetic metallic material, such as an aluminum alloy, a magnesium-infused aluminum alloy. The ferromagnetic element may be disposed partially along the length and/or width of the shank portion. The ferromagnetic element may be disposed parallel to a portion of the end portion. The stem 364 (including the stem portion 365) may be configured to taper toward the flexure. In other words, the cross-section of the shank 364 closer to the flexure 362 may be smaller than the cross-section of the shank 364 further from the flexure 362. In other words, at least a portion of the shank portion 365 may be disposed within the tapered portion. The opening may include a first opening 366 configured to receive a portion of the ring body 340 (e.g., half ring 342) therethrough. Hook body 360 may be rigidly attached (e.g., welded) to loop body 340. The plurality of hooks 360 may be disposed at substantially equal distances from adjacent hooks.

The openings may include a second opening 368 configured to receive the connector 322 that connects the hook 360 to the eyelet 324 from which a winch rope for lifting the bungee jumper back to the original (jumping) position may be secured.

In various embodiments, ring body 340 can include or consist of a pair of half rings 342.

In different embodiments, other numbers of hooks may be provided by the retrieval device 302, such as two, three, or more. Similarly, in other embodiments, the number of connectors may vary.

An example of a receiving device (e.g., 120) at the "jumper end" for retrieving a rope (e.g., 110), such as a bungee rope, according to various embodiments will be described below.

Fig. 4A shows a perspective view 400 of an exemplary receiving device (e.g., 120), and fig. 4B shows another perspective view 401 of the exemplary receiving device, according to one embodiment.

The receiving apparatus 402 may include or may refer to the same or similar elements or components as the receiving apparatus 120 of fig. 1B, and therefore, similar elements may be described in the context of the receiving apparatus 120 of fig. 1B, and thus, corresponding descriptions may be omitted herein.

As shown in fig. 4A and 4B, the receiving device (or "jumper end") 402 includes a central component 420 and a pad component 440.

The central member 420 may include a ring 422 disposed about or around the cord 110. The ring 422 may be connected to the cord 110.

The central member 420 may include a plurality of rings 424, e.g., 4, connected to a ring 422. The rings 424 may be disposed at substantially equal distances from adjacent rings. Each loop 424 may be formed from a portion of a support band 423 (e.g., a band) and at least another portion of the support band is coupled to a spool 428, as will be described later.

The central member 420 may include a plurality of guides 426, e.g., 4, each movably connected to a ring 424. Each guide 426 may be connected to the ring 424, for example, by sewing on. Each guide 424 may include a rotatable element configured to engage in rotatable contact with the handle 364 and/or handle portion 365 of the retrieval device 302 when magnetically coupling the retrieval device 302 with the receiving device 402. With the rotatable element, friction between guide 426 and stem 364 and/or stem portion 365 may be reduced. This reduces wear and prolongs the service life of the assembly.

The central component 420 may include a spool 428 or spool. A portion of each support band 423 that provides a loop 424 for engagement of the hook 360 may be connected to (e.g., at least partially encircle) the spool 428 and provide another loop to which a skipper may be attached. Another support band 425 (e.g., a strap) that does not provide loops for engagement of the hooks 360 may be received through an opening of the spool 428 and may provide at least one loop to which a skipper may be attached. The terminal end (or ends) of the cord 110 may be connected to (e.g., at least partially looped around) the spool 428.

The cushion component 440 may include an integrally formed first cushion portion as a top sleeve 442, a second cushion portion as a foam or cushion body 444, and a third cushion portion as a bottom or bobbin cover 446. The top sleeve 442, foam or cushion body 444, and bottom or spool cover 446 may comprise standard or high density polyethylene foam.

More specifically, top sleeve 442 may be disposed below annulus 424. The top sleeve 442 and the ring 422 are configured to insert the annulus 424 therebetween. The insert at least partially supports the ring 424 and protrudes the ring 424 from the central member 420.

The second pad section 444 can have a larger diameter than the first pad section and can be configured to allow the hooks to fall thereon and/or to prevent the retrieval device 302 from descending further and possibly hitting a jumper. The second pad section may have a height configured to approximate the stem section to the guide when the hook body falls on or contacts the second pad section.

The third cushion portion 446 may have at least one opening for allowing at least one strap 423, 425 to pass through, the strap being configured to be attached to a jumper.

Fig. 5A to 5D show schematic views illustrating a process of retracting the bellows 110.

As shown in fig. 5A, the retrieval device 302 is released to receive the cord 110 therein. In particular, first member 342 and second member 342 are released or moved away from each other to an open configuration in which an access is provided to receive a portion of cord 110. The retrieval device 302 is supported by a retrieval string (not shown) that is connected to the eyelet 324 of the retrieval device 302.

As shown in fig. 5B, the recovery device 302 is connected to the rope 110. In particular, first member 342 and second member 342 are moved toward one another to a closed configuration in which a portion of cord 110 is contained within recovery device 302. The first and second members 342, 342 are secured in the closed configuration by the locking pin 310. The recovery device 302 moves or descends along the rope 110 toward the receiving device 402. The rope 110 extends from an original (jump) location/position towards the jumper.

As shown in fig. 5C, the recovery device 302 is lowered until the recovery device 302 lands on the receiving device 402. In particular, the first padded portion or top sleeve 442 of the receiving device 402 is received into or through the opening (formed by the first and second members 342) of the retrieval device 302. The hook 360 contacts, e.g., is supported by, a second pad portion or pad 444 of the receiving device 402. The second pad section prevents the retrieval device 302 and its hook from further lowering and possibly hitting a skipper.

As shown in fig. 5D, the recovery device 302 is magnetically connected to the receiving device. In particular, the retrieval device 302 may be raised slightly toward the loop 424 during which the guide 426 may be in rotatable contact with the stem 364 of the hook 360. Since the shank 364, except for the shank portion 365, is non-ferromagnetic, there is no magnetic connection until the guide 426 is in contact with the shank portion 365. As the retrieval device 302 is further raised, the combination of the tapered shank portion 365 and the magnetic connection between the guide 426 and the shank portion 365 pulls the loop 424 to enlarge its opening and/or move into an engageable configuration in which the loop 424 extends sufficiently to receive the flexure 362. As the recuperator 302 is further raised, the ring 424 enters the gap 363 of the hook 360. As the retrieval device 302 is further raised, the flexure 362 is received in the loop 424 and mechanically engaged therewith. In the mechanical engagement, the recovery device 302 is magnetically separated from the receiving device. In particular, the combination of the absence of shank portion 365 (i.e., the ferromagnetic element) at flexure 362 and the interlocking of flexure portion 362 with loop 424 pulls guide 426 away from shank portion 365, thereby separating guide 426 from shank portion 365. When flexure 362 interlocks with ring 424, there is no magnetic interaction or coupling between them due to gap spacing 363. The loop 424 is thus disposed in an engaged configuration in which the recovery device 302 is ready to be raised back to the original (jumping) position with the receiving device 402 and the jumper. In this manner, the raising of the receiving device 402 and the skipper does not involve a magnetic connection, and the recovery device 302 can be mechanically separated from the receiving device 402 after raising the skipper back to the original (skipper) position. Such mechanical separation may be easier and faster than separating magnetically connected recovery and receiving devices.

Fig. 2A to 2C and 5A to 5D may illustrate the most suitable way of using the recovery device 100, 302 and the receiving device 120, 402 for recovery of a bungee jumper after completion of the bungee jump.
