Description

Recovery device for retrieving a rope, receiving device and method for using 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 the person (the jumper) jumps, the rope extends downwards towards 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 rope 110 with the receiving device 120 attached to one end portion of the rope 110. The retrieval device 100 includes a connector assembly 102 having an opening 104 configured to receive a portion of the cord 110 for moving the connector assembly 102 (or, effectively, the retrieval device 100) along the cord 110, as indicated by dashed line 112. At least a portion of the connection assembly 102 is adapted to magnetically couple 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.

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.

In the context of various embodiments, the phrase "magnetically connected" may refer to a magnetic connection or magnetic coupling or magnetically attracting or magnetically securing. For example, "magnetically connected" may mean that the magnetic force may be between a permanent magnet and a ferromagnetic (ferromagnetic) element, or between a permanent magnet and another permanent magnet.

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 connector assembly 102. In this manner, the linkage assembly 102 may move along the cable 110 with zero or minimal resistance to each other, thereby preserving the integrity of the cable 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 in close proximity to an end of the cord 110.

The phrase "opposite end portions of a cord" may refer to end portions of a cord 110 that extend away from the distal end portion of a cord 110, or may be the distal end portion of the cord 110 that is distal with respect to the distal end portion 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 in close proximity 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.

In the context of various embodiments, the term "toward an opposite end portion of a cord" may mean substantially near an end point of a cord 110 extending away from a 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 towards the opposite end portion of the rope" may refer to the connection assembly 102 moving upwards away from the ground to a position substantially at or near the height of the opposite end portion of said 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. A receiving device 120 may be attached to one end portion of the cord 110. For example, the recovery device 100 may be placed around the portion of the rope 110 at the opposite end portion of the rope 110 after the rope 110 has been extended from the opposite end portion of the rope 110. The recovery device 100 may be movable or may be lowered to the receiving device 120 and may be magnetically connected to the receiving device 120. When the recovery device 100 and the receiving device 120 are connected to each other, a retrieval member 106 may be used to move or raise 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 a recovery position. By doing so, the process of rope retraction can be performed automatically, without intervention by the jumper.

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 member and the second member are configured to move relative to each other between a closed configuration and an open configuration, wherein in the closed configuration, the first member and the second member are configured to move toward each other to form an 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.

In other words, in a closed configuration, the opening 104 may form a closed loop, and in an open configuration, the 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 inlet/outlet to receive or release a portion of the cord 110.

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

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

In another example, both the first member and the second member may be movable relative to each other.

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

In other words, the first member may be movable relative to the second member through a pivot point. For example, the pivot point may be a hinge. In this example, the connection assembly 102 may function similar to a clamp, while the first member and the second member may function similar to an arm of a clamp.

In various examples, the connection assembly 102 may function similar to an open-ended enclosure having an overlapping pendulum (overlapping pendulum) or snap-back pendulum (snap-back), 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 example, the connection assembly 102 may function like 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 examples, 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 member and the second member in the closed configuration.

For example, the locking mechanism may comprise 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, each of the first member and the second member may comprise a non-metallic body.

For example, the first member may comprise a body of plastic and similarly the second member may also comprise a body of plastic. The body of the first member may be made of the same material as the body of the second member. In some embodiments, the body of the first member may be made of a different material than the body of the second member. Other suitable materials may be used, the primary purpose being that the material allows the integrity of the rope 110 (e.g., the rubber of a bungee rope) to be protected and preserved from friction from ferromagnetic elements (e.g., steel plates) or permanent magnets (e.g., neodymium magnets), and/or any part or anything that may damage the connection assembly 102 of the rope 110.

The first member and the second member in the closed configuration may form a circle. It is to be understood and appreciated that although circular may be advantageously most effective in size and weight, other shapes may be formed in different embodiments.

In various embodiments, each of the first member and the second member may comprise a ferromagnetic element, wherein the respective ferromagnetic elements are disposed on a surface of the first member and on a surface of the second member, wherein the respective surfaces are configured to contact the receiving device 120. The ferromagnetic element may be a lightweight 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.

In other embodiments, each of the first member and the second member may comprise a permanent magnet, wherein the respective permanent magnet is disposed on a surface of the first member and on a surface of the second member, wherein the respective surfaces are configured to contact the receiving device 120.

In various embodiments, ferromagnetic elements or permanent magnets may be placed on other (additional) surfaces of the first member and/or the second member. It should be understood and appreciated, however, that the ferromagnetic elements or permanent magnets may not be placed on one or more surfaces of the first and/or second members that may cause possible damage to the cord 110.

In some embodiments, the ferromagnetic element or the permanent magnet may be embedded within the first member and/or the second member. In such a case, the embedment may be dimensioned in such a way that the force of the magnetic connection between the connection assembly 102 and the receiving means 120 may be strong enough to perform rope retrieval.

In various embodiments, a portion of the linkage assembly 102 may include a permanent magnet. In some examples, the permanent magnet of the connection assembly 102 may be used to magnetically connect to another permanent magnet of the receiving device 120. In one example, the permanent magnet of the connection assembly 102 may be made of the same material as the other permanent magnets of the receiving device 120. In different examples, the permanent magnet of the connection assembly 102 may be made of a different material than the other permanent magnets of the receiving device 120. In other examples, the permanent magnet of the connection assembly 102 may be used to magnetically connect to the ferromagnetic element of the receiving device 120.

For example, a portion of the connection assembly 102 may include a neodymium magnet.

In various embodiments, a portion of the connection assembly 102 may include a ferromagnetic element adapted to magnetically couple to a portion of the receiving device 120. In other words, the ferromagnetic element may be adapted to be magnetically coupled to a portion of the receiving device 120. For example, a ferromagnetic element of the connection assembly 102 may be used to magnetically connect to a permanent magnet of the receiving device 120.

For example, a portion of the connection assembly 102 may comprise a steel plate.

The recovery device 100 according to various embodiments may further include a guide member connected to the connection assembly 102, wherein the guide member is configured to guide the connection assembly 102 to move along the rope 110.

In various embodiments, the guide component may comprise a guide member, such as a roller ball.

For example, the rolling ball may have a diameter of about 2 cm, or about 3 cm, or about 4 cm, or about 5 cm. For example, the rolling ball may have a diameter ranging from about 2.5 cm to about 5 cm. The rolling ball may be a standard size rolling ball or a custom size rolling ball. The roller ball may be of sufficient size to provide guidance of the attachment assembly 102 along the cable 110. The roller ball may be spherical, or cylindrical, or any other shape suitable for providing guidance of the connection assembly 102 along the cable 110. The roller ball may be made of plastic, or rubber, or any other material suitable for providing guidance of the connection assembly 102 along the cable 110.

The guide member may be in contact with the received portion of the cord 110.

The recovery device 100 according to various embodiments may comprise at least two guide members, or at least three guide members, or at least four guide members, or at least five guide members, or at least six guide members, at least seven guide members, or at least eight guide members. Each guide member may be positioned at a substantially equal distance from an adjacent or neighboring guide member.

The guide member may be placed on at least one surface of the first member and/or at least one surface of the second member, wherein the respective surfaces are arranged to avoid contact with the receiving means 120.

The guide member may be disposed on a surface of the first member and/or a surface of the second member, wherein the respective surfaces are opposite to the surfaces on which the ferromagnetic elements or permanent magnets may be disposed.

In various embodiments, the retrieval member 106 may include a loop configured to receive a retrieval string.

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

In the context of various embodiments, the term "ring" may be interchangeably referred to as an eyebolt (eyebolt) or an eyelet (eyelet).

In various embodiments, the ring may be connected to the connection assembly 102. For example, the ring may be welded to the connection assembly 102.

In other embodiments, the ring may be an integral part of the ferromagnetic element. For example, the ring may be formed from a ferromagnetic element (e.g., a steel plate).

The ring may be of any shape. For example, the ring may be a conventional polygon, such as a circular ring, an oval, a triangle, a square, or a rectangle. The ring may also be of unconventional shape.

In various embodiments, the connection assembly 102 may include at least two loops, or at least three loops, or at least four loops. Each ring may be positioned at a substantially equal distance from an adjacent or neighboring ring.

The ring may be placed on at least one surface of the first member and/or at least one surface of the second member, wherein the respective surfaces are arranged to avoid contact with the receiving means 120.

Fig. 1B shows a cross-sectional schematic view of a receiving device 120 for retrieving a rope 110 for receiving a retrieval device 100, according to various embodiments. The receiving device 120 includes a central core 122; and a cushion member 124 surrounding at least a portion of the central core 122, as indicated by line 126. At least a portion of the central core 122 is adapted to be magnetically coupled to at least a portion of the recycling apparatus 100, as indicated by dashed line 114 through dashed line 112. The receiving means 120 can be attached towards one end portion of the cord 110, as indicated by the dashed line 114.

In the context of various embodiments, the term "surrounding" may refer to covering, enclosing, encapsulating, or encompassing.

The term "retracted" and the phrases "magnetically connected", "an end portion of a cord", "towards an end portion of a cord" may be described in a similar context to the above.

In various embodiments, the central core 122 may comprise an aluminum plate. For example, the aluminum plate may be a magnesium-impregnated aluminum plate.

In other embodiments, the central core 122 may include a plate made of an alloy that provides a high strength to weight ratio.

The receiving device 120 may be used to receive the retrieval device 100 moving from the opposite end portion of the line 110 toward the receiving device 120 at one end portion of the line 110.

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

In various embodiments, the central core 122 may include permanent magnets. In some examples, the permanent magnet of the central core 122 may be used to magnetically connect to another permanent magnet of the retrieval device 100. In one example, the permanent magnets of the central core 122 may be made of the same material as the other permanent magnets of the retrieval device 100. In various examples, the permanent magnets of the central core 122 may be made of a different material than the other permanent magnets of the retrieval device 100. In other examples, the permanent magnet of the central core 122 may be used to magnetically couple to a ferromagnetic element of the retrieval device 100.

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

In various embodiments, the central core 122 may include at least two permanent magnets, or at least three permanent magnets, or at least four permanent magnets. Each permanent magnet may be placed at a substantially equal distance from an adjacent or neighboring permanent magnet.

In various embodiments, the central core 122 may further include at least two spacers disposed across the permanent magnets for compensating for movement of the retrieval device 100 to provide a constant magnetic attraction between the retrieval device 100 and the receiving device 120. The term "constant" may mean consistent or continuous. The term "magnetic attraction" may also be referred to as a magnetic attraction force.

In other embodiments, the central core 122 may include a ferromagnetic element adapted to magnetically couple to a portion of the recycling apparatus 100. For example, the ferromagnetic element of the central core 122 may be used to magnetically connect to the permanent magnet of the retrieval device 100.

For example, the ferromagnetic element may comprise a steel plate.

In various embodiments, the central core 122 may include at least two ferromagnetic elements, or at least three ferromagnetic elements, or at least four ferromagnetic elements. Each ferromagnetic element may be positioned at a substantially equal distance from an adjacent or neighboring ferromagnetic element.

In various embodiments, the central core 122 may further include at least two spacers disposed across the ferromagnetic element for compensating for movement of the recovery device 100 to provide a constant magnetic attraction between the recovery device 100 and the receiving device 120.

One or more permanent magnets or one or more ferromagnetic elements may be attached to the aluminum plate (e.g., the central core 122).

As mentioned above, two spacers may be provided across the permanent magnet or the ferromagnetic element. For example, the central core 122 may include a plurality of spacers up to four spacers. In the case of a plurality of spacers, each spacer may be disposed between a plurality of permanent magnets or between a plurality of ferromagnetic elements.

In various embodiments, the spacers disposed across the permanent magnets or ferromagnetic elements may be used to compensate for movement and bending (flexing) of the retrieval device 100, such that a constant magnetic attraction may be obtained between the retrieval device 100 and the receiving device 120.

The spacer may be made of a resilient material, such as rubber.

The central core 122 having at least one of one or more permanent magnets or one or more ferromagnetic elements may form a planar structure.

In various embodiments, the central core 122 may further include an alignment element configured to facilitate orientation of the receiving device 120 relative to the orientation of the retrieval device 100 for providing a constant magnetic connection therebetween.

In the context of various embodiments, the term "constant" may mean uniformly or substantially uniformly distributed.

In various embodiments, the alignment element may be disposed along a central axis of the receiving device 120. For example, the alignment element may be a vertebral body structure.

In cross-section, the vertebral body structure may have a parabolic curve connecting the maximum outer diameter at the base of the vertebral body to the maximum outer diameter at the "tip" or tip of the vertebral body. The outer diameter of the vertebral body may be a few millimeters less than the inner diameter of the retrieval device 100 (or the opening 104). This may allow for proper alignment of the magnetic connection between the recovery device 100 and the receiving device 120. The outer diameter of the "tip" may need to be slightly larger (e.g. about 5 mm) than the thickest possible bungee cord (about 50 mm).

At 166, 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 the opposite end portion of the string 110.

The recovery device and the receiving device 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 "retrieving" and the phrases "magnetically connected," "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 coupling a recovery device to a receiving device" may also mean that the receiving device 100 and the receiving device 120 may be magnetically coupled or secured to each other.

The phrase "a pulling force is exerted on the retrieval string" or "exerting a pulling force on the retrieval string" may also mean applying a pulling force on the retrieval string, or raising the retrieval string.

The method 160 may further include releasably securing the first member and the second member.

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) (e.g., 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 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 described in the context of the recovery device 100 and the receiving device 120 of fig. 1A and 1B, respectively, and therefore the corresponding description may be omitted here.

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. The skipper 202 may be positioned at a platform 206 at a starting location (or may also be referred to as an original (jumping) location). The opposite end 208 (opposite end portion) of the cord 110 may be secured to the underlying surface of the platform 206 relative to the overlying surface of the platform 206, where the jumper 202 may be placed in the starting position, or secured to other suitable portions of the platform 206.

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

At instance (i), the jumper 202 may jump or move away from 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 substantially 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 rope) 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 schematic 220 illustrating an example snapshot of the bringing or lowering of retraction cord 212 to jumper 202. As shown in example (iv), when a 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 a 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 clamped around the bungee cord 110.

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

Upon reaching an end 204 (or an end portion) of the cord 110, the retrieval device 100 and the receiving device 120 may be secured to one another by a magnetic connection. 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 the retraction cord 212 retracted with the skipper 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), the winch 216 may pull the skipper 202 back up to the original (skip) location/position by winch rope 212. At the retrieval position (instance (ix)), retrieval apparatus 100 may be removed from the rope 110, and the jumper 202 may be released from the receiving apparatus 120 and the rope 110, for example 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 magnetically connected to the receiving device 120 with the cord 110 extending towards the ground, the magnetic attraction between the recovery device 100 and the receiving device 120 may be effective in a direction along the pull-up direction in which the cord 110 extends. This magnetic attraction may be strong enough to maintain the magnetic connection between the recovery device 100 and the receiving device 120 throughout the rope retraction process.

In a retrieval position, such as instance (ix), the retrieval device 100 may be removed from the receiving device 120 by sliding the retrieval device 100 laterally relative to the receiving device 120. In other words, the sliding movement may be in a direction perpendicular to the pull-up direction as mentioned above. This magnetic attraction may not be strong enough to maintain a magnetic connection between the retrieval device 100 and the receiving device 120 during removal (lateral sliding movement) of the retrieval device 100 from the receiving device 120. This may allow the recycling device 100 to be easily removed from the receiving device 120.

In general, the "jumper end" or receiving device 120 can be attached to the same end 204 (or the same end portion) of the bungee cord 110 as the bungee jumper 202 prior to starting a bungee jump. After the bungee jump is completed, the "retrieval end" may be attached to the bungee cord 110. Using the winch 216, the "recovery end" can be lowered the full length of the rope 110 to secure 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 the 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 320 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 thus, the 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 plastic body 304, a steel plate 306, rolling balls 322, and eyebolts 324.

The plastic body 304 may comprise or consist of two half-rings that are partially overlapped (overlapped) and fit together to form a complete ring. The two pieces (or two halves) may be hinged (via hinge 308) on one side to allow opening and closing of the two pieces. The opposite side may be provided with a locking pin 310 to prevent accidental opening. After the bungee jump is complete, the plastic body 304 can be opened, slid over the bungee cord (e.g., 110) and lowered along the cord 110 to the jumper (e.g., 202).

Once recovery of the bungee jumper is complete, the locking pins 310 can be unlocked and the "recovery end" 302 can be removed from the bungee cord. The plastic body 304 can provide a framework to anchor other components and can protect the bungee cord 110 from damage.

Two similarly shaped half-ring approximately 16 mm steel plates 306 may be provided into the underside of the plastic body 304. When recovering a jumper, these steel plates 306 may provide a sufficient amount of attraction to the magnet at the "jumper end" to safely maintain the bungee jumper. The steel plate 306 may also provide the primary structure from which the winch rope (e.g., 212) may be anchored.

The upper portion of the "retrieval end" 302 can be provided with eight rolling balls 322 that can also help protect the bungee cord 110 from damage and minimize friction when lowering the retrieval device 302 to the bungee cord 110.

Eyebolts 324 may provide attachment points for winch ropes (e.g., 212) that may be used to raise the bungee jumper back to the original (jumping) position.

In a different example (not shown in fig. 3A and 3B), for the "retrieval end" 302, the rolling balls (e.g., 322) may be integrated with the steel plate 306. For example, custom designed rolling balls (e.g., 322) and attachment points (e.g., 324) for the winch rope (e.g., 212) may be directly connected to the steel plate 306 by welding. In an alternative example, the attachment points (e.g., 324) may be integrally formed from the steel plate 306, rather than being welded. The custom designed rolling ball (e.g., 322) may include a housing within which the rolling ball (e.g., 322) rotates, and the housing may be integrally formed from the steel plate 306. In other words, the attachment points (e.g., 324) and the housings of the custom designed rolling balls (e.g., 322) may be formed from a single piece of steel plate.

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 an exploded view 420 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 thus, the similar elements may be described in the context of the receiving apparatus 120 of fig. 1B, and thus, the corresponding description may be omitted herein.

As shown in fig. 4A and 4B, the receiving device (or "jumper end") 402 may be considered or arranged in three different groups or portions, namely a central core (portion) 422, an outer pad portion 424, and an alignment cone (portion) 426.

The outer pad section 424 may include an upper section including an upper sleeve 428, a foam or cushioning body 430, and a spacer 436, and a lower section including a receiving spacer 434 and a bottom sleeve 436. The foam or cushioning body 430 may comprise standard polyethylene foam, which may be used to protect a jumper (e.g., 202) from side impact with the central core (portion) 422. Each of spacers 432 and receiving spacers 434 may comprise a high density polyethylene foam, which may be used to protect the skipper (e.g., 202) from impact with central core (portion) 422. Each of the top sleeve 428 and the bottom sleeve 436 may be made of vinyl-coated polyester fabric, which may serve to protect the foam from abrasion and tearing and may further serve to secure or lock all of the layers (the cushion body 430, the spacers 432, the central core (portion) 422, and the receiving spacers 434) therein. More specifically, the top sleeve 428 may fit closely around the damping body 430, which surrounds the central core (portion) 422. The top sleeve 428 may also be connected or attached to the bottom sleeve by four velcro patches (velcro tab) 438. The buffer body 430 may fit tightly around the spacer 432 surrounding the central core (portion) 422. The central core (portion) 422 may fit closely into or between the spacer 432 and the receiving spacer 434, but may not be secured to the spacer 432 and receiving spacer 434. The receiving spacer 434 may be secured to the bottom sleeve 436 by two velcro patches 440 inside or through the center hole of the bottom sleeve 436 and by four velcro patches extending from the sides of the bottom sleeve 436 toward the top. The outer liner portion 424 can protect the bungee jumper (e.g., 202) from damage during a bungee jump. The upper and lower sections may be described in a similar context to the first and second liner sections, respectively, described above.

The vertebral body (portion) 426 may be an important part of the device for retrieving the rope 110 (wherein the device may be referred to as a bungee recovery unit). The primary purpose of the vertebral body 426 may facilitate orienting the steel plate 306 of the "retrieval end" 302 directly over the magnet 504 (fig. 5A) of the "jumper end" 402. Without such a taper (portion), it may be difficult to obtain a constant or constant magnetic attraction between the retrieval device 302 and the receiving device 402.

Examples of the central core (portion) 422 may be further described with reference to fig. 5A to 5E. Fig. 5A shows an enlarged view 500 of the central core 422. Fig. 5B shows a top view 520 of the central core 422. Fig. 5C shows a side view 540 of the central core 422. Fig. 5D shows a cross-sectional view 560 from line B of fig. 5C. Fig. 5E shows a cross-sectional view 580 from line a of fig. 5B.

As shown in fig. 5A, the central core (portion) 422 of the "jumper end" 402 may include or consist of an aluminum plate 502, four magnets (or more specifically neodymium magnets) 504, and a rubber spacer 508.

The aluminum plate 502 may be the primary structural element of the "jumper end" 402. The aluminum plate 502 may need to have a strong enough structure to withstand weights of up to 200 kg, but may also be light enough not to affect the safety of the bungee jumper. For example, the aluminum plate 502 may be made of magnesium-infused aluminum (fusion plate 5052).

The four neodymium magnets 504 may be bolted to the aluminum plate 502 and may provide an attractive force (magnetic connection) between the "jumper end" 402 and the "recovery end" 302. The magnet 504 of the "jumper end" 402 may be attracted to the steel plate 306 of the "recovery end" 302. The temporary connection by magnetic force may be strong enough to safely maintain the bungee jumper when the winch rope (e.g., 212) lifts him back to the original (jumping) position, but nonetheless such temporary connection may be easily removable once the recovery operation is complete. This is possible because the magnet 504 can be strong when a force is applied perpendicularly, but only have a fraction of that strength when resisting parallel forces (sliding). When the recovery has been completed, the locking pin 302 may be removed from the "recovery end" 302 and the recovery device 302 may be opened by a hinge bolt 308. Once opened, there may be sufficient mechanical advantage to easily separate the two components (the half-rings of the recovery device 302) and reset for the next bungee jumper.

Each magnet 504 may be circular with a diameter of about 60 mm. The configuration of the magnets 504 may be based on the workload limit for the heaviest possible bungee jumper permitted for commercial jumps. In other examples, the magnets may be different shapes and/or different sizes. Custom shaped and sized magnets may also be used.

As shown in fig. 5B and 5D, the central core 422 of the "jumper end" 402 may include four rubber spacers 508 for the magnets 504. Each rubber spacer 508 for magnet 504 may be about 15 mm thick (fig. 5E). The magnet spacers 508 may compensate for the movement and flexure of the "retrieval end" 302 so that a constant magnetic attraction may be achieved.

Fig. 6A shows a schematic side view 600 illustrating the recovery device 302 moving along the line (e.g., 110) toward the receiving device 402. Fig. 6B shows a side cross-sectional view 620 of fig. 6A.

As shown in fig. 6A and 6B, the cord 110 can extend from an original (jump) site/position 602 toward a bungee jumper at 604.

All components, such as eyebolts 324, rolling balls 322, and steel plates 306 for connection to a winch rope (not shown in fig. 6A and 6B) may be mounted on the plastic body 304 of the recovery device 302.

The rolling balls 322 can guide the descent of the retrieval device 302 and protect the soft rubber of the bungee cord 110.

The steel plate 306 for magnetic attraction (magnetically connected) may be about 16 mm thick.

At 606, the "recovery end" 302 may be lowered along the bungee cord 110 until the "recovery end" 302 is connected with the "jumper end" 402.

The vertebral body 426 can be bolted around the bungee cord 110 and attached to the "jumper end" 402. High strength magnets 504 may be used for the steel plates 306 attached to the "retrieval end" 302.

Fig. 6C shows a schematic side view 640 illustrating the recovery device 302 moving along the rope 110 toward the receiving device 402 with a misalignment therebetween.

As shown in fig. 6C, when the "retrieval end" 302 is lowered along the bungee cord 110 until the "retrieval end" 302 contacts the "jumper end" 402 at 642, the "retrieval end" 302 may be misaligned relative to the "jumper end". When misaligned, the steel plate 306 may not contact the magnet 504. In the case of a misaligned 644, the vertebral body 426 may redirect the "retrieval end" 302 into the correct orientation relative to the "jumper end" 402 through an opening 646 (e.g., in a similar context to the opening 104 of the retrieval device 100 of fig. 1A).

Fig. 6D shows a schematic of a side view 660 illustrating the recovery device 302 and the receiving device 402 magnetically connected to each other for a rope retrieval process.

As shown in fig. 6D, by using the vertebral body 426 to obtain the correct or sufficient alignment 662 between the "retrieval end" and the "jumper end", the vertebral body 426 passes through the opening 646 of the "retrieval end" 302 and the steel plate 306 may be in contact with the magnet 504. With sufficient alignment between the "reclaim end" 302 and the "jumper end" 402 as shown in FIG. 6D, maximum strength of the magnetic connection can be achieved.

Figures 2A to 2C and 6A to 6D can illustrate the most suitable way of using the recovery apparatus 100, 302 and the receiving apparatus 120, 402 for recovery of a bungee jumper after completion of a bungee jump.

It should be appreciated that in any situation where the bungee jumping person's weight (or two or more jumping persons) exceeds 100 kg, the conditions and design requirements presented in the example recovery device 302 and the example receiving device 402 may exceed a maximum safe workload.

Materials that may be used in the above examples may be most suitable in view of the strength of the magnetic connection, the weight of the device 302, 402 and the jumper 202, and the durability of the rope and various components of the device 302, 402.

While the invention has been shown and described with reference to a particular embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. The scope of the invention is thus indicated by the appended claims, and all changes that come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
