These and other features of the present application will become more fully apparent from the following description and appended claims, or can be learned by practice of the principles set forth in this document.

[0112] Provided herein is a device for propelling a rope in the air. The device can include a handle, a head connected to a proximal end of the handle, at least one motor housed within the head, two driven wheels that are drivable by the at least one motor and rotatably mounted to the head, a detachable cover that can cover at least a portion of the two driven wheels, a looped rope that can be inserted into a gap between the two driven wheels, and at least one ultraviolet light source.

[0113] Many rope propelling devices (e.g., rope launchers) known in the art have drawbacks. For example, many rope propelling devices cannot be used in the dark, are prone to tangling the rope due to inadequate load configuration, are prone to overheating, and produce undesirable noise when operated. The rope propelling devices provided herein address these issues. The rope propelling devices utilize ultraviolet reactive ropes that can illuminate (e.g., glow in the dark), allowing the rope propelling devices to be used at any time of the day. Due to the novel rope loading mechanism employed, the rope propelling devices are easy to assemble and avoid tangling. The rope propelling devices provide dual functionality to the driven wheels, both propelling the rope and cooling the device. In addition, the rope propelling devices use a novel rope loop manufacturing method that utilizes a seamless rope connection point, thereby preventing undesirable noise and tangling during operation.

[0114] As Figure 1 , 4As shown in FIGS. 5, the device 100 can include a handle 104 and a head 102. A string 150 can be connected to the head 102 and propelled by the device 100, as further described herein. The string 150 can be a looped string (e.g., a string without an end). The head 102 can be connected to a proximal end of the handle 104. In some examples, the handle 104 and the head 102 can be manufactured as one unit. In another example, the head 102 can be configured to be coupled to the handle 104 using screws, snap-on connectors, permanent welds, or other coupling means known in the art. In some examples, the head 102 and the handle 104 can include two parts, a first portion 308 and a second portion 306, for example, as shown in FIGS. 6A and 6B. The first portion 308 can include a portion of the head 102 and a portion of the handle 104, and the second portion 306 can include a portion of the head 102 and a portion of the handle 104. The two portions 306, 308 can be coupled or decoupled from each other. Decoupling the first portion 308 and the second portion 306 can allow access to internal components of the device 100. In some aspects, the first portion 308 and the second portion 306 can be permanently coupled. In other examples, the first portion 308 and the second portion 306 can be detachably coupled using coupling mechanisms, such as screws and screw holes, snap-on connectors, magnets, latches, or other coupling mechanisms that can couple the first portion 308 and the second portion 306. Figure 16

[0115] The head 102 can include a detachable cover 106. The detachable cover 106 can have one or more front vents 108. The one or more front vents 108 can allow air to enter the device 100. The air can be drawn into the device 100 by the two driven wheels through the one or more front vents 108, as further described herein. The device 100 can also include a power switch 110. The power switch 110 can be in electrical communication with the at least one motor. The at least one motor can be capable of driving (e.g., rotating) the two driven wheels. The power switch 110 can have an on position and an off position. The on position of the power switch 110 turns on the at least one motor, and the off position of the power switch 110 turns off the at least one motor. The handle 104 can further include a button 112. The button 112 can turn on and off one or more ultraviolet light sources, as further described herein.

[0116] As Figure 2 ​As shown, the head 102 can include one or more rear vents 109 (e.g., on a side of the head opposite the detachable cap 106). The one or more rear vents 109 can allow air to exit the device 100. The head 102 can further include a charging port 116 and one or more indicator lights 114. The charging port 116 can be in electrical communication with one or more rechargeable batteries. The one or more rechargeable batteries can be housed within the head 102 or the handle 104. The one or more rechargeable batteries can be used to power the at least one motor and the one or more ultraviolet light sources. The charging port 116 can be a USB-A charging port, a USB-B charging port, a USB-C charging port, or any other type of charging port. The charging port 116 can be used to receive a charging cord connected to a power source to charge the one or more batteries in the device 100. The one or more indicator lights 114 can include a first indicator light and a second indicator light. In some examples, the first indicator light and the second indicator light can be different colors or the same color. In some examples, the first indicator light can change color depending on the status of the device 100. For example, the first indicator light can be green when the device 100 is in an on and charging state. The first indicator light can be off when the device 100 is in an off state. The first indicator light can be red when the device 100 is low on power. The second indicator light can turn on when the charging port 116 is connected to a power source, indicating that the device 100 is charging. The second indicator light can be off when the device is not connected to a power source.

[0117] In other examples, the one or more batteries can be disposable batteries. The device 100 can include a battery port in which a user can insert one or more disposable batteries to power the device 100.

[0118] As Figure 3As shown, the head 102 can include a first ultraviolet light source 118 on an upper surface (e.g., a surface opposite the sides of the handle 104). The first ultraviolet light source 118 can emit a first ultraviolet light. In some examples, the first ultraviolet light can have a wavelength of about 315 nm to about 330 nm, about 330 nm to about 345 nm, about 345 nm to about 360 nm, about 360 nm to about 375 nm, about 375 nm to about 390 nm, or about 390 nm to about 400 nm. The first ultraviolet light source 118 can be used to provide excitation light to the cord 150. As described further herein, the cord 150 can react to the ultraviolet light to produce a luminescent effect. In some examples, the first ultraviolet light source 118 can further include an ultraviolet light filter that can maximize the emission of 365 nm ultraviolet light while blocking any visible light emitted by the first ultraviolet light source 118. The ultraviolet light filter can narrow the bandwidth of the first ultraviolet light source 118. In some examples, the first ultraviolet light source 118 can be replaced by another type of light source (e.g., visible light, near infrared light, etc.). In other examples, one or more additional light sources (e.g., visible light sources, near infrared light sources, ultraviolet light sources) can be located on the upper surface of the head 102 with the first ultraviolet light source 118. In some examples, the first ultraviolet light source 118 and / or one or more additional light sources can be located on any surface of the head 102. In some examples, the first ultraviolet light source 118 and / or one or more additional light sources are located on the head 102 such that the first ultraviolet light source 118 and the one or more additional light sources can emit light to the cord 150.

[0119] In at least one example, the head 102 can have an upper protrusion that can mate with the removable cap 106 and form a gap such that the cord 150 fits within the gap. As shown, the head 102 can have an upper protrusion 126. The upper protrusion 126 can be located on the same side of the head 102 as the removable cap 106. The upper protrusion 126 can secure the cord 150. The upper protrusion 126 and the removable cap 106 can be configured to fit together such that the cord 150 fits within a gap formed by the edges of the upper protrusion 126 and the removable cap 106. In this manner, the cord 150 can be secured in a position that prevents the cord 150 from tangling. Figure 3 As shown, the head 102 can have an upper U-shaped protrusion 127. The upper U-shaped protrusion 127 can be located on the same side of the head 102 as the removable cap 106. The upper U-shaped protrusion 127 can secure the cord 150. The upper U-shaped protrusion 127 and the removable cap 106 can be configured to fit together such that the cord 150 fits within a gap formed by the edges of the upper U-shaped protrusion 127 and the removable cap 106. In this manner, the cord 150 can be secured in a position that prevents the cord 150 from tangling.

[0120] In at least one example, the head 102 can have a lower protrusion that can mate with the removable cap 106 and form a gap such that the cord 150 fits within the gap. Similar to the upper protrusion, the lower protrusion can be, for example, a U-shaped protrusion. In some examples, the lower protrusion can be located on the same side of the head 102 as the removable cap 106. In other examples, the lower protrusion can be located on a different side of the head 102 than the removable cap 106. In some examples, the lower protrusion can be located on the same side of the head 102 as the upper protrusion. In other examples, the lower protrusion can be located on a different side of the head 102 than the upper protrusion. Figure 6The lower U-shaped protrusion 126 is shown. The lower U-shaped protrusion 126 can be located on the same side of the head 102 as the removable cover 106. The lower U-shaped protrusion 126 can secure the rope 150. The lower U-shaped protrusion 126 and the removable cover 106 can be configured to fit together such that the rope 150 is fitted within the gap formed by the edges of the lower U-shaped protrusion 126 and the removable cover 106. In this way, the rope 150 can be secured in a position to prevent the rope 150 from tangling.

[0121] like Figures 6-7 As shown, the device 100 may include two wheels, a first wheel 120(a) and a second wheel 120.

[0122] (b). In some examples, both the first wheel 120(a) and the second wheel 120(b) can be driven wheels. First wheel 120

[0123] (a) and the second wheel 120(b) may each be coupled to a motor spindle connected to at least one motor. In some examples, the first wheel 120(a) may have a cap 129(a) and the second wheel 120(b) may have a cap 129.

[0124] (b). In some examples, caps 129(a) and 129(b) can be coupled to the corresponding motor spindle. Cap 129

[0125] (a) and 129(b) can generate frictional engagement with the corresponding motor spindle to engage the first wheel 120(a) and the second wheel 120.

[0126] (b) Attached to the motor spindle. In some examples, caps 129(a), 129(b) may be threaded onto corresponding threads on the corresponding motor spindle. Caps 129(a), 129(b) may have a set depth such that the first wheel 120(a) and the second wheel 120(b) are aligned (e.g., the farthest ends of the first wheel 120(a) and the second wheel 120(b) are equidistant from the head 102). In some examples, the first wheel 120(a) and the second wheel 120(b) may have separate motors (e.g., a first motor and a second motor). The at least one motor may be attached to a battery mounted inside the handle 104 and / or the head 102. A gap 140 for receiving the rope 150 may be present between the first wheel 120(a) and the second wheel 120(b). Along the outer periphery of the first wheel 120(a) and the second wheel 120(b), the first wheel 120...

[0127] (a) may have a groove 122(a), and the second wheel 120(b) may have a groove 122(b). The groove 122(a),

[0128] The grooves 122(a), 122(b) can ensure that the rope is held at a set distance from the head 102.

[0129] The first wheel 120(a) and the second wheel 120(b) can be driven by at least one motor at a rotational speed sufficient to propel the rope 150 through the air. In some examples, the first wheel 120(a) and the second wheel 120(b) can be driven by at least one motor operating at a rotational speed of at least about 40,000 revolutions per minute (rpm). In some examples, the at least one motor can operate at a rotational speed of about 40,000 rpm to about 45,000 rpm, about 45,000 rpm to about 50,000 rpm, about 50,000 rpm to about 55,000 rpm, about 55,000 rpm to about 60,000 rpm, or higher. The rope 150 can be propelled at a speed of about 20 miles per hour (mph) to about 25 mph, about 25 mph to about 30 mph, about 30 mph to about 35 mph, about 35 mph to about 40 mph, or greater.

[0130] about 55,000 rpm to about 60,000 rpm, or higher. The rope 150 can be propelled at a speed of about 20 miles per hour (mph) to about 25 mph, about 25 mph to about 30 mph, about 30 mph to about 35 mph, about 35 mph to about 40 mph, or greater.

[0131] The at least one motor can be equipped with a power cut-off switch. For example, the at least one motor can be in communication with a controller for controlling operation of the at least one motor. In some examples, it is desirable to control operation of the at least one motor automatically (e.g., without user input). For example, if the rope 150 is in the first wheel 120(a) and the second wheel 120(b) and the user is not holding the head 102, it can be desirable to automatically stop the at least one motor.

[0132] (b) between the at least one motor and the at least one rope. The at least one motor can have at least one sensor, such as a stress sensor, a current sensor, or other sensor that can determine a load, stress, and / or strain on the motor. If the load, stress, or strain on the at least one motor exceeds a threshold, the controller can automatically shut off the at least one motor, thereby preventing damage to the at least one motor. The threshold can be a threshold based on a percentage of a normal operating load, stress, and / or strain of the at least one motor. For example, the threshold can be about 110% to about 120%, about 120% to about 130%, about 130% to about 140%, about 140% to about 150%, or more of the normal operating load, stress, and / or strain of the at least one motor. In addition, shutting off the power can prevent the at least one motor from continuing to advance the entangled rope, thereby preventing damage to the entangled rope. The entangled rope can be removed and untangled or replaced with a new rope, and operation of the device 100 can resume to normal operating mode (e.g., functionality as described herein).

[0133] In at least one example, the power cut-off switch can be in communication with the controller and the at least one current sensor. The threshold can be determined by measuring the current (e.g., amperage) that is supplied to the at least one motor. In certain examples, the current is measured in amperes. The threshold for automatically activating the power cut-off switch and thereby shutting off the at least one motor can be determined by the type of motor used and the selected maximum current for the at least one motor. In some examples, the threshold is a measurement of current that prevents damage to the at least one motor.

[0134] The first wheel 120(a) can have a plurality of internal fan blades 124(a) and the second wheel 120(b) can have a plurality of internal fan blades 124(b). The plurality of internal fan blades 124(a), 124(b) can extend radially from the caps 129(a), 129(b) toward the outer periphery of the first wheel 120(a) and the second wheel 120(b), respectively. The internal fan blades 124(a), 124(b) can draw air into the device 100 through the one or more front vents 108 of the detachable cap 106. Behind the first wheel 120(a) and the second wheel 120(b) can be one or more air inlets. The air inlets can allow air to be drawn into the device 100 by the internal fan blades 124(a), 124(b) to enter the interior of the device 100. As cold air from outside of the device 100 is drawn into the device 100, the cold air can flow around the battery, the at least one motor, and other internal components within the device 100. The cold air can cool the internal components of the device 100, which can then flow out of the one or more rear vents 109 of the device. In this way, the internal components of the device 100 can be cooled, the temperature within the device 100 can be regulated, consistent performance can be maintained, and the risk of overheating can be reduced. In some examples, a heat sink can be located near the at least one motor and the battery, air can flow through the heat sink to carry away heat from the at least one motor and the battery, and the heat can be expelled out of the one or more rear vents 109. The internal fan blades 124(a), 124(b) can have a blade pitch of about 10 degrees to about 20 degrees, about 10 degrees to about 11 degrees, about 11 degrees to about 12 degrees, about 12 degrees to about 13 degrees, about 13 degrees to about 14 degrees, about 14 degrees to about 15 degrees, about 15 degrees to about 16 degrees, about 16 degrees to about 17 degrees, about 17 degrees to about 18 degrees, about 18 degrees to about 19 degrees, about 19 degrees to about 20 degrees, or more. The internal fan blades 124(a), 124(b) can be spaced symmetrically or asymmetrically. The first wheel 120(a) and the second wheel 120(b) can have about 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, or more internal fan blades.

[0135] The head 102 can further include one or more connection mechanisms that can detachably couple to one or more connection mechanisms of the detachable cap 106. For example, the one or more connection mechanisms on the head 102 can include first and second snap-in ports 128(a), 128(b) that correspond to first and second snap-in protrusions on the detachable cap 106. In other examples, other connection mechanisms can be used, such as magnets, latches,

[0136] Velcro hook and loop fastener strips, other snap-on devices, rotatable mating mechanisms, clips, and other mating / connection mechanisms that can connect the removable cover 106 to the head 102.

[0137] The device 100 can include a lower U-shaped protrusion 126. The lower U-shaped protrusion 126 can be located on the same side of the head 102 as the removable cover 106. The lower U-shaped protrusion 126 and the upper U-shaped protrusion 127 are able to align with the gap 140 between the two wheels 120(a), 120(b). When the removable cover 106 is coupled to the head 102, and the cord 150 is inserted in between the gap 140 and within the opening defined by the upper U-shaped protrusion 127 and the removable cover 106 and the lower U-shaped protrusion 126 and the removable cover 106, the cord 150 can be contained within the propulsion line defined by the gap 140, the gap formed by the upper U-shaped protrusion 127 and the removable cover 106, and the gap formed by the lower U-shaped protrusion 126 and the removable cover 106. In this way, the cord 150 is allowed to make some longitudinal movement (e.g., toward either side of the head 102), while also being prevented from tangling. In some examples, the upper U-shaped protrusion 127 and the lower U-shaped protrusion 126 can be other shapes. For example, the upper U-shaped protrusion 127 and the lower U-shaped protrusion 126 can be circular protrusions or square protrusions or other shapes with openings to contain the cord 150 such that the cord does not tangle when being propelled by the first wheel 120(a) and the second wheel 120(b).

[0138] Figures 8-14 A device 100 in another example is shown. The device 100 can include a head 102 and a handle 104. The device 100 can include a removable cover 106. The removable cover 106 can include a first vent 208(a) and a second vent 208(b). The first vent 208(a) and the second vent 208(b) can each include one or more air holes. The first vent 208(a) can correspond to the first wheel 120(a) and the second vent 208(b) can correspond to the second wheel 120(b). In some examples, the removable cover 106 can be made of a transparent or translucent material. In some examples, the removable cover 106 can include a transparent ultraviolet reactive material that can emit light. In some examples, the ultraviolet reactive material of the removable cover 106 can be provided with excitation light from a second ultraviolet light source (e.g., an internal ultraviolet light source), as further described herein.

[0139] In some examples, the removable cover 106 may be made of a UV-reactive material in a pattern. For example, different UV materials can be used to form a pattern in the removable cover. The removable cover 106 may include fluorescent and / or phosphorescent materials. In some examples, the pattern may include various graphic designs, natural patterns, objects, and any other desired designs. In some examples, excitation light from a second UV light source (e.g., an internal UV light source) may be provided to the UV material of the removable cover, as further described herein.

[0140] like Figure 8 As shown, the device 100 may include a drive wheel 210 on a handle 104. The drive wheel 210 can be used to actuate the at least one motor, thereby driving (e.g., rotating) the first wheel 120(a) and the second wheel 120(b). The drive wheel 210 allows for more precise control of the speed of the first wheel 120(a) and the second wheel 120(b) than the power switch 110 described above. The drive wheel 210 can be rotated by the user to control the rotational rate of the at least one motor. For example, rotating the drive wheel 210 turns on the at least one motor, and the faster the drive wheel 210 rotates, the greater the power supplied to the at least one motor, thereby providing a faster rotational rate to the motor spindle and the first wheel 120(a) and the second wheel 120(b).

[0141] The device 100 may also include a button 212. The button 212 can control the first ultraviolet light source 118 and the second ultraviolet light source 242, such as... Figures 13-14 As shown. Button 212 can have one or more modes. In one example, button 212 can have four modes. Button 212 can cycle through the four modes by clicking button 212. For example, clicking button 212 for the first time enters the first mode. In the first mode, the first ultraviolet light source 118 can be turned on (e.g., the first ultraviolet light source 118 starts emitting light). Clicking button 212 for the second time enters the second mode. In the second mode, the first ultraviolet light source 118 can be turned off, and the second ultraviolet light source 242 can be turned on. Clicking button 212 for the third time enters the third mode. In the third mode, both the first ultraviolet light source 118 and the second ultraviolet light source 242 are turned on. Clicking button 212 for the fourth time enters the fourth mode. In the fourth mode, both the first ultraviolet light source 118 and the second ultraviolet light source 242 are turned off. In other examples, other configurations and modes can be used. For example, button 212 can have only an on mode for the first click and an off mode for the second click. In another example, it can be understood that the four modes can cycle through different numbers of clicks.

[0142] The device 100 may further include one or more indicator lights. For example... Figures 8-9As shown, device 100 may include three indicator lights 230(a), 230(b), and 230(c). These three indicator lights 230(a), 230(b), and 230(c) can indicate the battery level of the device. For example, when all three indicator lights 230(a), 230(b), and 230(c) are illuminated, the battery level of device 100 is fully charged. When only two of the three indicator lights 230(a), 230(b), and 230(c) are illuminated, the battery level of device 100 has slightly decreased. When all three indicator lights 230(a), 230(b), and 230(c) are illuminated...

[0143] When only one of the lights is on, the battery power of device 100 is low, indicating to the user that the device should be charged.

[0144] like Figure 8 As shown, the device 100 may further include an on / off indicator light 234. The on / off indicator light 234 can indicate to the user whether the device 100 is in an on or off state. When the on / off indicator light 234 is lit, the device 100 is in an on state. When the on / off indicator light 234 is off, the device 100 is in a off state. As described above, the device 100 can be turned on by actuating the power switch 110 or the drive wheel 210.

[0145] like Figure 8 and Figure 10 As shown, the device 100 may also include one or more high-intensity lamps. In one example, the device may include a first high-intensity lamp 232(a) and a second high-intensity lamp 232(b) located on the head 102, as shown. Figure 8 As shown. Figure 10 As shown, the device 100 may also include a third high-intensity lamp 232(c) and a fourth high-intensity lamp 232(d) on the side of the head 102 opposite to the first high-intensity lamp 232(a) and the second high-intensity lamp 232(b).

[0146] like Figures 9-11 As shown, device 100 may have one or more rear vents 209 on its rear surface. In some examples, the one or more rear vents 209 may be mesh-like and configured to allow airflow out of device 100. In some examples, the one or more rear vents 209 may be part of a removable rear cover configured to connect to head 102 on a side opposite to removable cover 106. The removable rear cover allows access to the interior of the device. For example, the removable rear cover may be detachably attached to head 102 using magnets, snap-fit ​​connectors, latches, Velcro hooks and loops, or other connecting mechanisms that allow the removable rear cover to be attached to head 102.

[0147] like Figures 13-14As shown, device 100 may include a first ultraviolet light source 118 and a second ultraviolet light source 242. The first ultraviolet light source 118 may be used to provide ultraviolet light to the rope 150. The first ultraviolet light source 118 may be located on the upper outer surface of the head 102 and may provide ultraviolet light to a portion of the rope 150 outside the removable cover 106. In some examples, the rope 150 may be made of an ultraviolet-reactive material (e.g., phosphor or fluorescent dye). The ultraviolet light provided by the first ultraviolet light source 118 may cause the phosphor or fluorescent dye of the rope 150 to emit light, thereby producing a luminescent effect. The first ultraviolet light source 118 may have a filter configured to filter the light provided by the first ultraviolet light source 118 to wavelengths of approximately 350 nm to approximately 380 nm, approximately 360 nm to approximately 375 nm, or approximately 365 nm. The filter is capable of filtering the light so that it is invisible to an observer.

[0148] The second ultraviolet light source 242 can be located near the first round 120(a) and the second round 120(b), for example, Figure 14 As shown. The second ultraviolet light source 242 can be configured to provide light to a portion of the cord 150 inside the removable cover 106. The second ultraviolet light source 242 can also provide excitation light to the removable cover 106. The second ultraviolet light source 242 can provide ultraviolet light with wavelengths of about 315 nm to about 330 nm, about 330 nm to about 345 nm, about 345 nm to about 360 nm, about 360 nm to about 375 nm, about 375 nm to about 390 nm, or about 390 nm to about 400 nm. In some examples, the second ultraviolet light source 242 may have a filter configured to filter the light provided by the second ultraviolet light source 242 to wavelengths of about 350 nm to about 380 nm, about 360 nm to about 370 nm, or about 365 nm. The filter can filter the light so that it is invisible to the observer. The ultraviolet light provided by the second ultraviolet light source 242 can cause the phosphor or fluorescent dye of the cord 150 to emit light, thereby producing a luminescent effect. When the cord 150 contains phosphorescent powder, the second ultraviolet light source 242 can charge the phosphorescent powder as a portion of the cord 150 passes through the removable cover 106. After a period of time, the phosphorescent powder emits light received from the second ultraviolet light source 242, thereby producing a luminescent effect. In some examples, the first ultraviolet light source 118 and the second ultraviolet light source 242 can be 3W ultraviolet lamps.

[0149] like Figure 19 As shown, the position of the first ultraviolet light source 118 can be offset from the center point of the head 102. By offsetting the first ultraviolet light source 118 from the center of the head, the light is emitted at a wider angle, thereby minimizing the unilluminated area of ​​the rope 150.

[0150] like Figure 14As shown, the head 102 can include one or more connection mechanisms configured to detachably couple to one or more connection mechanisms of the detachable cover 106. The one or more connection mechanisms on the head 102 can include a first magnet 228(a), a second magnet 228(b), a third magnet 228(c), and a fourth magnet 228(d). As shown, the first magnet 228(a) and the second magnet 228(b) can be configured to magnetically couple to the first magnet 600(a) and the second magnet 600(b) of the detachable cover 106. Similarly, the third magnet 228(c) and the fourth magnet 228(d) can be configured to magnetically couple to the third magnet and the fourth magnet of the detachable cover 106. Figure 20A and Figure 20B As shown, the detachable cover 106 can have corresponding connection mechanisms to detachably couple to the one or more connection mechanisms of the head 102. Figure 20B As shown, the first magnet 600(a) and the second magnet 600(b) can detachably couple to the first magnet 228(a) and the second magnet 228(b) of the head 102. Similarly, the detachable cover 106 can have a third magnet and a fourth magnet that can detachably couple to the third magnet 228(c) and the fourth magnet 228(d) of the head 102. It should be understood that other connection mechanisms described herein and / or that can be used to connect the detachable cover 106 to the head 102 can be used to detachably couple the detachable cover 106 to the head 102. Detachably coupling the detachable cover 106 to the head 102 provides a number of benefits. For example, if the cord 150 is wrapped within the detachable cover 106, the user is able to easily remove the cover and untangle the cord 150.

[0151] Figure 16 Internal components of the device 100 are shown. The device 100 can include a first motor spindle 300(a) and a second motor spindle 300(b). The cap 129(a) of the first wheel 120(a) can be configured to couple to the first motor spindle 300(a). For example, the cap 129(a) can form a friction fit with the first motor spindle 300(a), or have threads such that the cap 129(a) is screwed onto corresponding threads of the first motor spindle 300(a), or be coupled using other connection mechanisms that can couple the cap 129(a) to the first motor spindle 300(a). The cap 129(b) of the second wheel 120(b) can be configured to couple with the second motor spindle 300(b). For example, the cap 129(b) can form a friction fit with the second motor spindle 300(b), or have threads such that the cap 129(b) is screwed onto corresponding threads of the second motor spindle 300(b), or be coupled using other connection mechanisms that can couple the cap 129(b) to the second motor spindle 300(b). In this way, the first wheel 120(a) and the second wheel 120(b) can be mounted to the first motor spindle 300(a) and the second motor spindle 300(b), and thus be rotatably mounted to the head 102.

[0152] The first motor spindle 300(a) and the second motor spindle 300(b) can be coupled to at least one motor. In some examples, the at least one motor may include a first motor and a second motor. The first motor and the second motor can be configured to rotate the first motor spindle 300(a) and the second motor spindle 300(b), thereby rotating the first wheel 120.

[0153] (a) and the second wheel 120 (b). In another example, the first motor spindle 300 (a) and the second motor spindle 300

[0154] (b) It can be integrated with a motor. The motor can rotate the first motor shaft 300(a) and the second motor shaft 300(b), thereby rotating the first wheel 120(a) and the second wheel 120(b). In some examples, the first wheel 120(a) and the second wheel 120(b) can rotate in opposite directions. For example, the first wheel 120(a) can rotate counterclockwise and the second wheel 120(b) can rotate clockwise, or vice versa.

[0155] like Figure 16 and Figure 18 As shown, the device 100 may further include an air inlet that can receive air drawn in from the external environment by the internal fan blades 124(a), 124(b) of the wheel. In one example, the head 102 may include air inlets 302(a), 302(b), 302(c), 302 for allowing air to enter the interior of the device 100.

[0156] (d), 304(a), 304(b).

[0157] like Figures 18-19 As shown, the head 102 may include two cavities. The head 102 may include a first cavity 500(a) and a second cavity 500(b). The first cavity 500(a) may be used to house a first motor that rotates the first wheel 120(a). The second cavity may be used to house a second motor that rotates the second wheel 120(b). In another example, the head 102 may include a single cavity for housing a single motor. The single motor is capable of driving (e.g., rotating) the first motor spindle 300(a) and the second motor spindle 300(b), thereby driving (e.g., rotating) the first wheel 120(a) and the second wheel 120(b).

[0158] like Figure 18As shown, the head 102 may also include an aluminum circuit board 502. A first ultraviolet light source 118 may be connected to the aluminum circuit board 502. In one example, the first ultraviolet light source 118 may be soldered to the aluminum circuit board 502. In another example, both the first ultraviolet light source 118 and the second ultraviolet light source 242 may be soldered to the aluminum circuit board 502. The aluminum circuit board 502 may act as a heat sink, drawing heat generated by the first ultraviolet light source 118 and / or the second ultraviolet light source 242 into the airflow provided by the internal fan blades 124(a), 124(b). It is understood that the aluminum circuit board 502 may be made of various materials known in the art that can be used as heat sinks.

[0159] like Figures 15-18 As shown, device 100 may include a cooling system. The cooling system may include internal fan blades 124(a), 124(b) of the first wheel 120(a) and the second wheel 120(b), one or more front vents 108 of a removable cover 106 or a first vent 208(a) and a second vent 208(b), an aluminum circuit board 502, and an air inlet 302.

[0160] (a), 302(b), 302(c), 302(d), 304(a), 304(b), and one or more rear vents 109 or one or more rear vents 209. When the first wheel 120(a) and the second wheel 120(b) are driven by a motor, the internal fan blades 124(a), 124(b) draw in air through one or more front vents 108 or the first vent 208(a) and the second vent 208(b). Air flows through the air inlets 302(a), 302(b) of the head 102.

[0161] 302(c), 302(d), 304(a), 304(b) flow into the interior of head 102. As the first wheel 120(a) and the second wheel 120(b) are continuously driven, air is continuously drawn into head 102. The air can then flow over the motor and aluminum circuit board 502, carrying away heat from the motor and aluminum circuit board 502. Air can be exhausted from head 102 of device 100 at one or more rear vents 109 or one or more rear vents 209.

[0162] Figure 17Airflow paths are shown. Air can flow along first airflow path 402, second airflow path 404, and third airflow path 406. Air can enter the device through air inlets 302(a), 302(c) and flow around the upper surfaces of the first motor 400 and the second motor (not shown) and then exit from one or more back vents 109 or one or more back vents 209 in the first airflow path 402. The first airflow path 402 can also carry heat away from the aluminum circuit board 502 from the one or more back vents 209. In the second airflow path 404, air can flow through air inlets 304(a), 304(b) around the first motor 400 and the second motor (not shown) and then exit from one or more back vents 109 or one or more back vents 209. In the third airflow path 406, air can flow through air inlets 302(b), 302(d) and around the lower surfaces of the first motor 400 and the second motor (not shown) and then exit from one or more back vents 109 or one or more back vents 209. In this way, the motors, the ultraviolet light source, and other internal components of the device 100 can be kept at a regulated operating temperature, thereby extending battery life and preventing the device 100 from overheating. In some examples, the cooling system can further include one or more heat sinks proximate to the one or more electric motors, and air can pass through these heat sinks to further cool the one or more electric motors.

[0163]

[0164] Figures 21-23 Rope 150 is shown. Rope 150 can be a looped rope as shown in Figures 22-23 Rope 150 can include a mixture of cotton and polyester material. The polyester can melt under high-temperature heat treatment, thereby providing a connection point between the two ends of the rope to form a looped rope. The cotton material can reduce the weight of the rope and provide enough friction and surface texture to be pushed into the air, thereby creating a levitation effect. As shown in Figure 21 Rope 150 can have a first end and a second end that are permanently joined at a connection point 700. Although connection point 700 is shown in Figures 21-23 Connection point 700 is invisible to the human eye and has approximately the same diameter as rope 150. The connection point is seamless, thereby preventing a clicking sound or bounce when rope 150 is pushed by the first wheel 120

[0165] (a) and the second wheel 120(b). In some examples, the total length of the looped rope can be about 1 foot to about 10 feet or any length therebetween.

[0166] Rope 150 can have two ends, a first end 702 and a second end 704. The two ends of the rope can be put into a mold.

[0167] ​The mold can be configured such that heat is transferred to the interior of the mold, but the mold does not melt or otherwise change shape.

[0168] The mold can be provided with heat to melt the polyester in the first end 702 and the second end 704. In some examples, the temperature can be about 245 degrees Celsius to about 265 degrees Celsius, about 265 degrees Celsius to about 285 degrees Celsius, about 285 degrees Celsius to about 305 degrees Celsius, about 305 degrees Celsius to about 325 degrees Celsius, about 345 degrees Celsius to about 365 degrees Celsius, about 365 degrees Celsius to about 385 degrees Celsius, or about 385 degrees Celsius to about 400 degrees Celsius. The mold can be able to maintain the shape of the cord 150 such that the connection point 700 has the same diameter or substantially the same diameter as the rest of the cord. Once the polyester in the first end 702 and the second end 704 is melted in the mold, the mold can be cooled, thereby cooling the polyester on the connection point 700 and permanently connecting the first end 702 and the second end 704. In some examples, a force or pressure can be applied to form the connection point 700 with a desired diameter (e.g., approximately equal to the diameter of the other portions of the cord) as the first end 702 and the second end 704 are melted in the mold. In this way, the first end 702 and the second end 704 form a seamless connection, and a looped cord is formed.

[0169] In one example, the mold can maintain the diameter of the connection point 700 below the diameter of the gap 140 between the first wheel 120(a) and the second wheel 120(b). In some examples, the mold can maintain the diameter of the connection point 700 to a maximum diameter of about 0.5 millimeters to about 0.6 millimeters. The gap 140 between the first wheel 120(a) and the second wheel 120(b) can be configured to have a maximum diameter of 0.7 millimeters, thereby preventing any rattling caused by the connection point as the device 100 propels the cord through the air. Additionally, maintaining the diameter of the connection point 700 below the diameter of the gap 140 can stabilize the movement of the cord 150 through the air, preventing any bounce or unnecessary movement of the cord 150. Exemplary systems and methods for forming the cord 150 will be further described herein.

[0170] As shown in FIG. 8A, the cord 150 can include a plurality of cords. As shown in FIG. 8B, the cord 150 can include a first cord 802 and a second cord 806. The first cord 802 can have two ends, a first end and a second end. The first end and the second end of the first cord 802 can be permanently joined to the first end and the second end of the second cord 806 at connection points 800, 804 using the cord joining methods described herein. Figures 22-23 Figure 22 As shown in FIG. 8A, the cord 150 can include a plurality of cords. As shown in FIG. 8B, the cord 150 can include a first cord 802 and a second cord 806. The first cord 802 can have two ends, a first end and a second end. The first end and the second end of the first cord 802 can be permanently joined to the first end and the second end of the second cord 806 at connection points 800, 804 using the cord joining methods described herein. Figure 23 ​As shown, the ropes can include a first rope 802, a second rope 806, and a third rope 810. The ends of the first rope 802, the second rope 806, and the third rope 810 can be permanently joined at the connection points 800, 804, 808 using the rope connection systems and methods described herein.

[0171] The first rope 802 and the second rope 806 can further include ultraviolet reactive materials. The first rope 802 and the second rope 806 can be dyed with fluorescent dyes that emit different colors when ultraviolet light is shined on them. When the first ultraviolet light source 118 and / or the second ultraviolet light source 242 provides light to the ropes, the ropes can emit different colors of light, creating a sparkling visual effect when propelled through the air. To an observer, this sparkling visual effect can appear as a momentary color change of the ropes. Similarly, the first rope 802, the second rope 806, and the third rope 810 can be dyed with fluorescent dyes that emit different colors when ultraviolet light is shined on them. In some examples, 4, 5, 6, 7, 8, 9, 10, or more different ropes can be connected using the rope connection systems and methods described herein, and all or some of the ropes can include ultraviolet reactive materials.

[0172] The first rope 802 and the second rope 806 can further include ultraviolet reactive materials. The first rope 802 and the second rope 806 can be dyed with fluorescent dyes that emit different colors when ultraviolet light is shined on them. When the first ultraviolet light source 118 and / or the second ultraviolet light source 242 provides light to the ropes, the ropes can emit different colors of light, creating a sparkling visual effect when propelled through the air. To an observer, this sparkling visual effect can appear as a momentary color change of the ropes. Similarly, the first rope 802, the second rope 806, and the third rope 810 can be dyed with fluorescent dyes that emit different colors when ultraviolet light is shined on them. In some examples, 4, 5, 6, 7, 8, 9, 10, or more different ropes can be connected using the rope connection systems and methods described herein, and all or some of the ropes can include ultraviolet reactive materials.

[0173] In another example, the ultraviolet reactive material can be a phosphorescent material (e.g., phosphorescence). The phosphorescent material can be provided with ultraviolet light by the first ultraviolet light source 118 and / or the second ultraviolet light source 242. The second ultraviolet light source 242 can provide excitation light to portions of the ropes 150 in the detachable cover 106, after which the ropes can emit light. Similar to fluorescent ropes, phosphorescent ropes can be combined in different light-emitting color combinations, and multiple ropes can be used. In some examples, the phosphorescence is charged by the second ultraviolet light source 242 within the detachable cover 106. The phosphorescence can have a delayed light-emitting time, such that once the phosphorescence in the ropes 150 is outside of the detachable cover 106, the phosphorescence begins to emit light. In this way, the visual illumination of the phosphorescence can occur without the need for ultraviolet light from the first ultraviolet light source 118 (e.g., an external ultraviolet light source). By charging the phosphorescence within the detachable cover 106 by the second ultraviolet light source 242, an observer can be surprised that the ropes 150 do not emit light when entering the detachable cover 106, but do emit light when exiting the detachable cover 106. Furthermore, by charging the phosphorescence by the second ultraviolet light source 242, the visual effect can be achieved in low light conditions without the need for the first ultraviolet light source 118 to provide excitation light (e.g., the first ultraviolet light source 118 is turned off or not included in the device 100).

[0174] In some examples, the phosphor in the string 150 is still charged by the excitation light after the second ultraviolet light source 242 is turned off, causing the string 150 to continue to glow. In this way, an observer can be surprised by the continued glow of the string 150 when the first ultraviolet light source 118 or the second ultraviolet light source 242 is not providing excitation light.

[0175] In some examples, the looped string can include multiple strings, each string having a different ultraviolet reactive material to glow in a different color. For example, the multiple strings can be arranged in a rainbow pattern, a two-color alternating pattern, a three-color alternating pattern, a four-color alternating pattern, or a combination thereof.

[0176] As shown in FIGS. 1A and IB, the string 150 can be connected to the device 100. As described herein, the string 150 is connected to the device with the gap 140 between the first wheel 120(a) and the second wheel 120(b), the upper U-shaped protrusion 127 and the lower U-shaped protrusion 126, and the detachable cover 106. When the string 150 is connected to the device, the string 150 can be pushed in the air and appear to be floating. The speed at which the string 150 is pushed by the first wheel 120(a) and the second wheel 120(b) can enable the string 150 to float in the air. A user can move the handle 104 in their hand to make different shapes and patterns with the string 150. Additionally, the fluorescent dye used on the string can provide a flashing color effect, causing the string 150 to appear to change color instantaneously. Figure 1 Figure 12 As shown in FIGS. 1A and IB, the string 150 can be connected to the device 100. As described herein, the string 150 is connected to the device with the gap 140 between the first wheel 120(a) and the second wheel 120(b), the upper U-shaped protrusion 127 and the lower U-shaped protrusion 126, and the detachable cover 106. When the string 150 is connected to the device, the string 150 can be pushed in the air and appear to be floating. The speed at which the string 150 is pushed by the first wheel 120(a) and the second wheel 120(b) can enable the string 150 to float in the air. A user can move the handle 104 in their hand to make different shapes and patterns with the string 150. Additionally, the fluorescent dye used on the string can provide a flashing color effect, causing the string 150 to appear to change color instantaneously.

[0177] A string propulsion kit is also provided herein. The string propulsion kit can include one or more looped strings described herein, any device described herein, and packaging.

[0178] Figures 25A-25F A system 2500 for forming a string described herein is shown. The system 2500 can form a single continuous string from two or more strings, and / or form a looped string from a single string or two or more strings. For example, the system 2500 can receive two ends of one or more strings and connect the ends of the one or more strings. The system 2500 can connect the ends by heating the ends, thereby melting the ends, which can then be connected. The system 2500 can then move the melted ends together such that the ends contact within a mold or other mechanism. The system 2500 can then provide a compressive force to the ends, thereby connecting the melted ends and forming a single string. In some examples, the melted ends are connected at a connection point. The connection point can have substantially the same diameter as the rest of the string, such that the entire string has a consistent and uniform diameter.

[0179] As shown in FIGS. 1A and IB, the string 150 can be connected to the device 100. As described herein, the string 150 is connected to the device with the gap 140 between the first wheel 120(a) and the second wheel 120(b), the upper U-shaped protrusion 127 and the lower U-shaped protrusion 126, and the detachable cover 106. When the string 150 is connected to the device, the string 150 can be pushed in the air and appear to be floating. The speed at which the string 150 is pushed by the first wheel 120(a) and the second wheel 120(b) can enable the string 150 to float in the air. A user can move the handle 104 in their hand to make different shapes and patterns with the string 150. Additionally, the fluorescent dye used on the string can provide a flashing color effect, causing the string 150 to appear to change color instantaneously. Figures 25A-25F ​As shown, system 2500 can include a first rope holding mechanism 2506, a second rope holding mechanism 2516, a drive arm 2508, a compression mechanism 2514, a base 2502, and at least one heating device (e.g., first heating device 2512(a)). Figure 25A A first rope 2504 is shown secured in the first rope holding mechanism 2506. Each of the first rope holding mechanism 2506 and the second rope holding mechanism 2516 can secure a rope within the system 2500. The first rope holding mechanism 2506 and the second rope holding mechanism 2516 can each secure one rope such that one end of each rope extends outside of the first rope holding mechanism 2506 and the second rope holding mechanism 2516. In some examples, the first rope holding mechanism 2506 can be any type of mechanism for securing a rope such that the rope does not move, translate, or slide relative to the first rope holding mechanism 2506. The second rope holding mechanism 2516 can be any type of mechanism for securing a rope such that the rope does not move, translate, or slide relative to the second rope holding mechanism 2516. In some examples, the first rope holding mechanism 2506 and the second rope holding mechanism 2516 can be a clamp or other mechanism for securing a rope.

[0180] Figure 25B A close-up view of the system 2500 is shown. As shown, the first rope holding mechanism 2506 can include a first holding mechanism upper portion 2526 and a first holding mechanism lower portion 2524. The first holding mechanism upper portion 2526 and / or the first holding mechanism lower portion 2524 can be vertically movable within the system 2500. For example, the first holding mechanism upper portion 2526 can be vertically movable upward or downward. Similarly, the first holding mechanism lower portion 2524 can be vertically movable upward or downward. When a rope is placed between the first holding mechanism upper portion 2526 and the first holding mechanism lower portion 2524, the first holding mechanism upper portion 2526 and / or the first holding mechanism lower portion 2524 can be moved such that the first holding mechanism upper portion 2526 contacts the first holding mechanism lower portion 2524 and the rope is secured therein. In some examples, the first holding mechanism lower portion 2524 can not be vertically movable.

[0181] or the first holding mechanism lower portion 2524 is moved such that the first holding mechanism upper portion 2526 contacts the first holding mechanism lower portion 2524 and the rope is secured therein. In some examples, the first holding mechanism lower portion 2524 can not be vertically movable.

[0182] The second rope holding mechanism 2516 can include a second holding mechanism upper portion 2528 and a second holding mechanism lower portion 2530. The second holding mechanism upper portion 2528 and / or the second holding mechanism lower portion 2530 can be vertically movable within the system. For example, the second holding mechanism upper portion 2528 can be vertically movable upward or downward. Similarly, the second holding mechanism lower portion 2530 can be vertically movable upward or downward. When a rope is placed between the second holding mechanism upper portion 2528 and the second holding mechanism lower portion 2530, the second holding mechanism upper portion 2528 and / or the second holding mechanism lower portion 2530 are moved so that the second holding mechanism upper portion 2528 contacts the second holding mechanism lower portion 2530 and the rope is secured therein. In some examples, the second holding mechanism lower portion 2530 is not vertically movable.

[0183] The system 2500 can include at least one heating device. The at least one heating device can provide heat to the ends of the one or more ropes, thereby melting the one or more ropes. In some examples, the heat provided is heated air or gas that reaches or exceeds the melting point of the one or more ropes, such that the ends of the ropes are melted by the at least one heating device. The at least one heating device can be positioned between the first rope holding mechanism 2506 and the second rope holding mechanism 2516, such that heat can be provided to both ends of a single rope or to the ends of a first rope and a second rope, thereby melting. In some examples, the system can include a first heating device 2512(a) and a second heating device 2512(b). The first heating device 2512(a) can provide heat to the ends of the ropes secured in the second rope holding mechanism 2516. The second heating device 2512(b) can provide heat to the ends of the ropes secured in the first rope holding mechanism 2506.

[0184] The system can include a compression mechanism 2514. The compression mechanism 2514 can provide pressure or force to the melted ends of the ropes, thereby joining the ends of the two ropes to form a single continuous rope. In some examples, the compression mechanism 2514 can include a mold within the compression mechanism. For example, the two melted ends to be joined can be placed in the mold portion, and then pressure or force can be provided by the compression mechanism 2514, thereby forming a continuous rope. In some examples, the mold can have substantially the same diameter as the ropes, such that when the melted ends are joined, the single continuous rope has a consistent and uniform diameter.

[0185] In at least one example, the compression mechanism 2514 can be located between the first heating device 2512(a) and the second heating device 2512(b). In some examples, the compression mechanism 2514 can be located between the first string holding mechanism 2506 and the second string holding mechanism 2516. In some examples, the compression mechanism 2514 can also be a heating device, such that the at least one heating device and the compression mechanism 2514 are the same component. When the at least one heating device and the compression mechanism 2514 are the same component, the compression mechanism 2514 can be located between the first string holding mechanism 2506 and the second string holding mechanism 2516.

[0186] As shown in FIG. 25, the compression mechanism 2514 can include an upper compression component 2520 and a lower compression component 2522. The upper compression component 2520 and the lower compression component 2522 can connect the melted ends of the one or more strings. For example, the upper compression component 2520 and the lower compression component 2522 can provide pressure or force to the melted ends of the one or more strings, thereby forming a continuous string. In some examples, the upper compression component 2520 and / or the lower compression component 2522 can move vertically. For example, the upper compression component 2520 can move up or down within the system 2500. Similarly, the lower compression component 2522 can move up or down within the system 2500. In some examples, the lower compression component 2522 is fixed vertically within the system 2500 (e.g., the lower compression component 2522 can not move vertically within the system 2500). Figures 25A-25F As shown in FIG. 25, the compression mechanism 2514 can include an upper compression component 2520 and a lower compression component 2522. The upper compression component 2520 and the lower compression component 2522 can connect the melted ends of the one or more strings. For example, the upper compression component 2520 and the lower compression component 2522 can provide pressure or force to the melted ends of the one or more strings, thereby forming a continuous string. In some examples, the upper compression component 2520 and / or the lower compression component 2522 can move vertically. For example, the upper compression component 2520 can move up or down within the system 2500. Similarly, the lower compression component 2522 can move up or down within the system 2500. In some examples, the lower compression component 2522 is fixed vertically within the system 2500 (e.g., the lower compression component 2522 can not move vertically within the system 2500).

[0187] Figures 25A-25F As shown in FIG. 25, the compression mechanism 2514 can include an upper compression component 2520 and a lower compression component 2522. The upper compression component 2520 and the lower compression component 2522 can connect the melted ends of the one or more strings. For example, the upper compression component 2520 and the lower compression component 2522 can provide pressure or force to the melted ends of the one or more strings, thereby forming a continuous string. In some examples, the upper compression component 2520 and / or the lower compression component 2522 can move vertically. For example, the upper compression component 2520 can move up or down within the system 2500. Similarly, the lower compression component 2522 can move up or down within the system 2500. In some examples, the lower compression component 2522 is fixed vertically within the system 2500 (e.g., the lower compression component 2522 can not move vertically within the system 2500).

[0188] ​In some examples, the upper compression member 2520 and the lower compression member 2522 may each have a semi-circular mold on their contact surfaces (e.g., the surfaces of the upper compression member 2520 and the lower compression member 2522 that contact each other). The molten ends of one or more ropes may be loaded into the semi-circular mold of the lower compression member 2522 such that when the upper compression member 2520 moves to contact the lower compression member 2522, the molten ends combine to form a single rope. In some examples, the diameter of the semi-circular combination is equal to the diameter of one or more strings, such that the molten ends joined together have approximately the same diameter as the one or more ropes.

[0189] Figure 25C The system 2500 in the loading position is shown. In the loading position, the upper portion 2526 of the first retaining mechanism can be in a vertically raised position (e.g., the upper portion 2526 of the first retaining mechanism is not in contact with the lower portion 2524 of the first retaining mechanism). The first rope 2504 can be loaded into the first rope retaining mechanism 2506 by placing the first rope 2504 on the lower portion 2524 of the first retaining mechanism. Figure 25C As shown, the first rope 2504 may have an end 2538 extending from the first rope holding mechanism 2506 toward the second heating device 2512(b), thereby allowing the end 2538 to be heated by the second heating device 2512(b). Once the first rope 2504 is properly positioned (e.g., the end 2538 extends longitudinally outward from the first rope holding mechanism 2506 toward the second heating device 2512(b)), the upper portion 2526 of the first holding mechanism may be lowered vertically to contact the lower portion 2524 of the first holding mechanism, as indicated by arrow 2536. In some examples, the upper portion 2526 of the first holding mechanism may be slidably coupled to a guide rail that allows vertical movement of the upper portion 2526 of the first holding mechanism. In some examples, the upper portion 2526 of the first holding mechanism may be manually slid or moved by an operator along the guide rail to contact the lower portion 2524 of the first holding mechanism. In some examples, the upper portion 2526 of the first holding mechanism may be vertically positioned along the guide rail by a motor or actuator communicating with a controller. In some examples, the upper part 2526 of the first retaining mechanism may have a fixing mechanism (e.g., a snap-fit ​​mechanism, a magnetic mechanism, etc.) for fixing the upper part 2526 of the first retaining mechanism to the corresponding fixing mechanism of the lower part 2524 of the first retaining mechanism, thereby fixing the first rope 2504 inside the first rope retaining mechanism 2506.

[0190] In the loading position, the upper part 2528 of the second retaining mechanism can be in a vertically raised position (e.g., the upper part 2528 of the second retaining mechanism is not in contact with the lower part 2530 of the second retaining mechanism). The second rope 2532 can be loaded into the second rope retaining mechanism 2516 by placing the second rope 2532 on the lower part 2530 of the second retaining mechanism. Figure 25CAs shown, the second cord 2532 can have an end portion 2540 that extends out from the second cord retention mechanism 2516 toward the first heating device 2512(a), allowing the end portion 2540 to be provided with heat by the first heating device 2512(a). Once the second cord 2532 is properly positioned (e.g., has an end portion 2540 that extends longitudinally outward from the second cord retention mechanism 2516 toward the first heating device 2512(a)), the second retention mechanism upper portion 2528 can be lowered vertically to contact the second retention mechanism lower portion 2530, as indicated by arrow 2534. In some examples, the second retention mechanism upper portion 2528 can be slidably coupled to a rail that can allow the second retention mechanism upper portion 2528 to move vertically. In some examples, the second retention mechanism upper portion 2528 can be manually slid or moved by an operator along the rail to contact the second retention mechanism lower portion 2530. In some examples, the second retention mechanism upper portion 2528 can be vertically positioned along the rail by a motor or actuator in communication with a controller. In some examples, the second retention mechanism upper portion 2528 can have a securing mechanism (e.g., a snap-on mechanism, a magnetic mechanism, etc.) for securing the second retention mechanism upper portion 2528 to a corresponding securing mechanism of the second retention mechanism lower portion 2530, thereby securing the second cord 2532 within the second cord retention mechanism 2516.

[0191] Figure 25D The system 2500 is shown in a heating position. In the heating position, the first cord retention mechanism 2506 is moved longitudinally with the stationary first cord 2504 toward the second heating device 2512(b) such that the end portion 2538 of the first cord 2504 is aligned with the second heating device 2512(b). In some examples, the first cord retention mechanism 2506 can be slidably coupled to a rail such that the first cord retention mechanism 2506 is longitudinally movable in the system 2500. In some examples, other mechanisms can be used to enable the first cord retention mechanism 2506 to move longitudinally in the system 2500. In some examples, an operator can manually move the first cord retention mechanism 2506 toward the second heating device 2512(b) to align the end portion 2538 with the second heating device 2512(b). In some examples, the first cord retention mechanism 2506 can be moved toward the second heating device 2512(b) via a motor or actuator in communication with a controller. Once the end portion 2538 of the first cord 2504 is aligned with the second heating device 2512(b), the second heating device 2512(b) can provide heat (e.g., heated air or gas) to the end portion 2538, thereby melting the material at the end portion 2538 of the first cord 2504.

[0192] Likewise, in the heating position, the second cord retention mechanism 2516 is moved longitudinally with the second cord 2532 toward the first heating device 2512(a) such that the end portion 2540 of the second cord 2532 is aligned with the first heating device 2512(a). In some examples, the second cord retention mechanism 2516 can be slidably coupled to a rail such that the second cord retention mechanism 2516 is longitudinally movable in the system 2500. In some examples, other mechanisms can be used to enable the second cord retention mechanism 2516 to move longitudinally in the system 2500. In some examples, an operator can manually move the second cord retention mechanism 2516 toward the first heating device 2512(a) to align the end portion 2540 with the first heating device 2512(a). In some examples, the second cord retention mechanism 2516 can be moved toward the first heating device 2512(a) via a motor or actuator in communication with a controller. Once the end portion 2540 of the second cord 2532 is aligned with the first heating device 2512(a), the first heating device 2512(a) can provide heat (e.g., heated air or gas) to the end portion 2540, thereby melting the material at the end portion 2540 of the second cord 2532. Figure 25DAt the illustrated heating position, the second cord holding mechanism 2516 is moved longitudinally with the stationary second cord 2532 toward the first heating device 2512(a) such that the end 2540 of the second cord 2532 is aligned with the first heating device 2512(a). In some examples, the second cord holding mechanism 2516 can be slidably coupled to a rail such that the second cord holding mechanism 2516 can be moved longitudinally in the system 2500. In some examples, other mechanisms can be used to enable the second cord holding mechanism 2516 to be moved longitudinally in the system 2500. In some examples, an operator can manually move the second cord holding mechanism 2516 toward the first heating device 2512(a) to align the end 2540 with the first heating device 2512(a). In some examples, the second cord holding mechanism 2516 can be moved toward the first heating device 2512(a) via a motor or actuator in communication with a controller. Once the end 2540 of the second cord 2532 is aligned with the first heating device 2512(a), the first heating device 2512(a) can provide heat (e.g., heated air or gas) to the end 2540, thereby melting the material at the end 2540 of the second cord 2532.

[0193] The first heating device 2512(a) and the second heating device 2512(b) can be controlled by a controller (e.g., the controller can receive user input regarding temperature, duration, and heating time). In some examples, the first heating device 2512(a) and / or the second heating device 2512(b) can provide heat at a temperature sufficient to melt the first cord 2504 and / or the second cord 2532. In some examples, the temperature can be about 245 degrees Celsius to about 265 degrees Celsius, about 265 degrees Celsius to about 285 degrees Celsius, about 285 degrees Celsius to about 305 degrees Celsius, about 305 degrees Celsius to about 325 degrees Celsius, about 345 degrees Celsius to about 365 degrees Celsius, about 365 degrees Celsius to about 385 degrees Celsius, or about 385 degrees Celsius to about 400 degrees Celsius. In some examples, the temperature can depend on the material of the cord to be melted. The temperature can be between the melting point and the ignition point of the material of the cord to be melted.

[0194] Figure 25E A compression mechanism loading position of the system 2500 is illustrated. In the compression mechanism loading position, the end 2538 of the first cord 2504 is loaded into the lower compression component 2522 of the compression mechanism 2514. The end 2538 can be loaded into the lower compression component 2522 of the compression mechanism 2514 by moving the first cord holding mechanism 2506 in the direction of the compression mechanism 2514. As described herein, the first cord holding mechanism 2506 is capable of being moved longitudinally throughout the system 2500. The arrow 2542 illustrates the movement of the first cord holding mechanism 2506 in the compression mechanism loading position.

[0195] In the compression mechanism loading position, the end 2540 of the second cord 2532 is loaded into the lower compression component 2522 of the compression mechanism 2514. The end 2540 can be loaded into the lower compression component 2522 of the compression mechanism 2514 by moving the second cord holding mechanism 2516 toward the compression mechanism 2514. As described herein, the second cord holding mechanism 2516 is capable of longitudinal movement throughout the system 2500. Arrow 2544 illustrates the movement of the second cord holding mechanism 2516 in the compression mechanism loading position. In some examples, the end 2538 of the first cord 2504 and the end 2540 of the second cord 2532 are loaded into the lower compression component 2522 such that the end 2538 contacts the end 2540. In some examples, the end 2538 and the end 2540 are loaded in the lower compression component 2522 such that the end 2538 and the end 2540 overlap one another.

[0196] Figure 25F A forming position of the system 2500 is illustrated. In the forming position, the upper compression component 2520 is driven downward toward the lower compression component 2522. The upper compression component 2520 can be coupled to the drive arm 2508. The drive arm 2508 can drive the upper compression component 2520 downward to contact the lower compression component 2522 to provide pressure or force to the ends 2538, 2540 of the first cord 2504 and the second cord 2532. Arrow 2546 illustrates the movement of the drive arm 2508 in the forming position. In some examples, the pressure or force provided by the upper compression component 2520 to the ends 2538, 2540 when the ends 2538, 2540 have been melted causes the ends 2538, 2540 to connect to one another. As described herein, the ends 2538, 2540 can be connected by force or pressure such that the ends 2538, 2540 form a uniform and consistent diameter with the first cord 2504 and the second cord 2532. In this manner, the first cord 2504 and the second cord 2532 are connected and have a uniform and consistent diameter. In some examples, the pressure or force provided by the upper compression component 2520 and the drive arm 2508 is controlled by a controller through user input (e.g., user input of pressure or force to apply).

[0197] In some examples, the system 2500 can further include one or more fans. The one or more fans can cool the ends 2538, 2540 of the first cord 2504 and the second cord 2532 after the ends 2538, 2540 are connected. For example, the one or more fans can provide cool air to the ends 2538, 2540 to cool the ends 2538, 2540.

[0198] Also provided herein is a method for manufacturing a looped cord, Figure 24The method 2400 is shown. The method 2400 can begin at block 2402. At block 2402, the method 2400 can include providing one or more cords. In some examples, the cords include a UV-reactive material, such as a fluorescent dye, a phosphorescent material, or other UV-reactive material known in the art. In some examples, the one or more cords include 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or more cords. The cords can include a mixture of cotton material and polyester material.

[0199] At block 2404, the method 2400 includes placing the ends of the one or more cords in a mold. The mold can be configured to transfer heat to the interior of the mold, but the mold does not melt or otherwise change shape. In some examples, only the two ends are placed in a single heat-resistant mold. Multiple molds can be provided to connect multiple cords. The mold can have a diameter of about 0.1 millimeters to about 1 millimeter, or about 0.5 millimeters to about 0.6 millimeters.

[0200] At block 2406, the method 2400 can include providing heat to the mold to melt the polyester material in the ends of the one or more cords. In some examples, the heat can be provided at a temperature of about 245 °C to about 265 °C, about 265 °C to about 285 °C, about 285 °C to about 305 °C, about 305 °C to about 325 °C, about 345 °C to about 365 °C, about 365 °C to about 385 °C, or about 385 °C to about 400 °C.

[0201] At block 2408, the method 2400 can include cooling the mold. The mold is cooled to allow the polyester ends of the one or more cords to be permanently connected together with a diameter defined by the mold. In some examples, the diameter of the connected ends is the same or substantially the same as the diameter of the remainder of the one or more cords. In some examples, the method 2400 can be repeated to connect multiple cords until a looped cord including the multiple cords is formed.

[0202] Also provided herein is a method 2600 for manufacturing a cord described herein. Figure 26 The method 2600 is shown. In some examples, the method 2600 can form a continuous looped cord including multiple segments having different materials, such as different fluorophores, phosphors, and / or colors.

[0203] At block 2602, the method 2600 can begin by loading a first rope segment into a first rope holding mechanism and loading a second rope segment into a second rope holding mechanism. In some examples, a first end of the first rope segment can extend longitudinally out of the first rope holding mechanism and a second end of the second rope segment can extend longitudinally out of the second rope holding mechanism. In some examples, the method 2600 can include securing the first rope segment to the first rope holding mechanism such that the first rope segment does not move relative to the first rope holding mechanism. In some examples, the first rope holding mechanism can be a clamp or other mechanism that can secure the first rope segment. In some examples, the method 2600 can include securing the second rope segment to the second rope holding mechanism such that the second rope segment does not move relative to the second rope holding mechanism. In some examples, the second rope holding mechanism can be a clamp or other mechanism that can secure the second rope segment.

[0204] At block 2604, the method 2600 can include heating the first end of the first rope segment and the second end of the second rope segment, thereby melting the first end and the second end. In some examples, to heat the first end and the second end, the first rope holding mechanism and the second rope holding mechanism are translated longitudinally such that the first end and the second end are aligned with at least one heating device. In some examples, the at least one heating device can provide heated air or gas to the first end and the second end. In some examples, the at least one heating device provides heat at a temperature sufficient to melt the first end and the second end. In some examples, the temperature can be about 245 degrees Celsius to about 265 degrees Celsius, about 265 degrees Celsius to about 285 degrees Celsius, about 285 degrees Celsius to about 305 degrees Celsius, about 305 degrees Celsius to about 325 degrees Celsius, about 345 degrees Celsius to about 365 degrees Celsius, about 365 degrees Celsius to about 385 degrees Celsius, or about 385 degrees Celsius to about 400 degrees Celsius. In some examples, the temperature can depend on the material of the rope to be melted. The temperature can be between the melting point and the ignition point of the material of the rope to be melted. In some examples, the at least one heating device can include a first heating device to heat the first end and a second heating device to heat the second end.

[0205] At block 2606, the method 2600 can include bringing the first end of the first rope segment into contact with the second end of the second rope segment. Bringing the first end and the second end into contact can include moving, translating, and / or sliding the first rope holding mechanism and the second rope holding mechanism in close proximity. In some examples, the first end and the second end are in contact when loaded into the compression mechanism. In some examples, the compression mechanism can include a mold, a channel, or other geometry that can receive the first end and the second end. In some examples, the compression mechanism receives the first end and the second end in a mold, a channel, or other geometry that is configured to form the first end and the second end into a connecting rope having the same or substantially the same diameter as the first rope segment and the second rope segment. In some examples, the compression mechanism can include an upper compression portion and a lower compression portion. The melted ends can be received in the lower compression portion. In some examples, the lower compression portion and the upper compression portion can each form half of a mold or channel that can join the melted ends and form a diameter consistent with the first rope segment and the second rope segment.

[0206] At block 2608, the method 2600 can include providing a force or pressure to the first end of the first rope segment and the second end of the second rope segment, thereby connecting the first end to the second end. The force or pressure can be provided by the compression mechanism (e.g., the upper compression component can be moved downward to contact the lower compression component, thereby providing a force or pressure on the ends of the rope segments). In some examples, the force or pressure connects the melted first end and the melted second end, and forms the melted first end and the melted second end to a desired diameter. For example, the melted first end and the melted second end can be formed to a diameter defined by the mold or channel. In some examples, the formed diameter of the first end and the second end is approximately equal to the diameter of the first rope segment and the second rope segment, thereby forming a continuous rope having a consistent and uniform diameter.

[0207] In some examples, the method 2600 can include cooling the connected first end and second end. Cooling the connected first end and second end can include providing cool air via one or more fans or allowing the connected first end and second end to cool at room temperature.

[0208] In some examples, the method 2600 can be repeated multiple times to connect multiple rope segments together. In some examples, the method 2600 is complete when an end of a continuous rope (including multiple segments) is connected to another end of the continuous rope, and a looped rope is formed.
