These and other features of the present application will become more apparent from the following description and the appended claims, or can be learned by practicing the principles set forth herein.

[0101] A device for propelling a rope in the air is provided herein. The device may include a handle, a head connected to the proximal end of the handle, at least one motor housed in the head, two driven wheels drivable by the at least one motor and rotatably mounted to the head, a removable cover covering at least a portion of the two driven wheels, an endless rope insertable into a gap between the two driven wheels, and at least one ultraviolet light source.

[0102] Many rope propulsion devices (e.g., rope launchers) known in the art have disadvantages. For example, many rope propulsion devices cannot be used in the dark, are prone to rope entanglement due to insufficient load configuration, are prone to overheating, and produce undesirable noise during operation. The rope propulsion device provided herein solves these problems. The rope propulsion device utilizes a UV-responsive rope that can be illuminated (e.g., glow in the dark), allowing the rope propulsion device to be used at any time of the day. Due to the use of a novel rope loading mechanism, the rope propulsion device is easy to assemble and avoids entanglement. The rope propulsion device provides a dual function for the driven wheel, which can both propel the rope and cool the device. In addition, the rope propulsion device uses a novel rope loop manufacturing method and utilizes seamless rope connection points to prevent undesirable noise and entanglement during operation.

[0103] like Figure 1 , 4As shown in Figures 5 and 6, the device 100 may include a handle 104 and a head 102. A rope 150 may be connected to the head 102 and propelled by the device 100, as further described herein. The rope 150 may be a looped rope (e.g., a rope without ends). The head 102 may be connected to the proximal end of the handle 104. In some examples, the handle 104 and the head 102 may be manufactured as a single unit. In another example, the head 102 may be configured to be coupled to the handle 104 using screws, snap-on connectors, permanent welds, or other connection methods known in the art. In some examples, the head 102 and the handle 104 may include two parts, a first part 308 and a second part 306, such as Fig.16 As shown. The first portion 308 may include a portion of the head 102 and a portion of the handle 104, and the second portion 306 may include a portion of the head 102 and a portion of the handle 104. The two portions 306, 308 can be coupled or uncoupled to each other. Uncoupling the first portion 308 and the second portion 306 can allow access to the 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 removably coupled using a coupling mechanism, such as a screw and a screw hole, a snap-on connection, a magnet, a latch, or other coupling mechanism that can couple the first portion 308 and the second portion 306.

[0104] The head 102 may include a removable cover 106. The removable cover 106 may have one or more front vents 108. The one or more front vents 108 may allow air to enter the device 100. Air may be sucked into the device 100 by the two driven wheels through the one or more front vents 108, as further described herein. The device 100 may also include a power switch 110. The power switch 110 may be in electrical communication with at least one motor. The at least one motor is capable of driving (e.g., rotating) the two driven wheels. The power switch 110 may 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 may further include a button 112. The button 112 may turn on and off the one or more ultraviolet light sources, as further described herein.

[0105] like Figure 2As shown, the head 102 may include one or more rear vents 109 (e.g., on a side of the head opposite to the removable cover 106). The one or more rear vents 109 may allow air to be exhausted from the device 100. The head 102 may further include a charging port 116 and one or more indicator lights 114. The charging port 116 may be in electrical communication with one or more rechargeable batteries. The one or more rechargeable batteries may be housed in the head 102 or the handle 104. The one or more rechargeable batteries may be used to power the at least one motor and the one or more ultraviolet light sources. The charging port 116 may 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 may be used to receive a charging cable connected to a power source to charge the one or more batteries in the device 100. The one or more indicator lights 114 may include a first indicator light and a second indicator light. In some examples, the first indicator light and the second indicator light may be different colors or the same color. In some examples, the first indicator light may change color depending on the state of the device 100. For example, when the device 100 is turned on and charging, the first indicator light may be green. When the device 100 is in a closed state, the first indicator light may be off. When the device 100 is low on power, the first indicator light may be red. When the charging port 116 is connected to a power source, the second indicator light may be on, indicating that the device 100 is charging. When the device is not connected to a power source, the second indicator light may be off.

[0106] In other examples, the one or more batteries may be disposable batteries. Device 100 may include a battery port into which a user may insert one or more disposable batteries to power device 100.

[0107] like Figure 3As shown, the head 102 may include a first ultraviolet light source 118 located on an upper surface (e.g., a surface on the opposite side of the handle 104). The first ultraviolet light source 118 may emit a first ultraviolet light. In some examples, the wavelength of the first ultraviolet light may be about 315nm to about 330nm, about 330nm to about 345nm, about 345nm to about 360nm, about 360nm to about 375nm, about 375nm to about 390nm, or about 390nm to about 400nm. The first ultraviolet light source 118 may be used to provide excitation light to the rope 150. As further described herein, the rope 150 may react to the ultraviolet light to produce a luminous effect. In some examples, the first ultraviolet light source 118 may further include an ultraviolet filter, which can maximize the emission of 365nm ultraviolet light while blocking the first ultraviolet light source 118 from emitting any visible light. The ultraviolet filter can narrow the bandwidth of the first ultraviolet light source 118. In some examples, first ultraviolet light source 118 may be replaced by another type of light source (e.g., visible light, near infrared light, etc.). In other examples, the one or more additional light sources (e.g., visible light source, near infrared light source, ultraviolet light source) may be located on the upper surface of head 102 together with first ultraviolet light source 118. In some examples, the first ultraviolet light source 118 and / or one or more additional light sources may be located on any surface of head 102. In some examples, the first ultraviolet light source 118 and / or one or more additional light sources may be located on any surface of head 102. Or one or more additional light sources are located on the head 102 so that the first ultraviolet light source 118 and the one or more additional light sources can emit light to the rope 150.

[0108] In at least one example, the head 102 can have an upper protrusion that can cooperate with the removable cover 106 and form a gap so that the cord 150 fits within the gap. Figure 3 As shown, the head 102 may have an upper U-shaped protrusion 127. The upper U-shaped protrusion 127 may be located on the same side of the head 102 as the removable cover 106. The upper U-shaped protrusion 127 can secure the cord 150. The upper U-shaped protrusion 127 and the removable cover 106 may be configured to fit together so that the cord 150 fits within a gap formed by the upper U-shaped protrusion 127 and the edge of the removable cover 106. In this way, the cord 150 can be secured in a position that prevents the cord 150 from being entangled.

[0109] In at least one example, the head can have a lower protrusion that can cooperate with the removable cover 106 and form a gap so that the rope fits into the gap. Similar to the upper protrusion, the lower protrusion can be, for example Figure 6The lower U-shaped protrusion 126 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 fix the rope 150. The lower U-shaped protrusion 126 and the removable cover 106 can be configured to fit together so that the rope 150 fits in the gap formed by the lower U-shaped protrusion 126 and the edge of the removable cover 106. In this way, the rope 150 can be fixed in a position to prevent the rope 150 from being entangled.

[0110] like Figure 6 to Figure 7 As shown, the device 100 may include two wheels, a first wheel 120 (a) and a second wheel 120 (b). In some examples, both the first wheel 120 (a) and the second wheel 120 (b) can be driven wheels. The first wheel 120 (a) and the second wheel 120 (b) may each be coupled to a motor spindle, which is 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 (b). (b). In some examples, the caps 129 (a), 129 (b) may be combined with the corresponding motor spindles. (a), 129 (b) can produce friction fit with the corresponding motor spindle to move the first wheel 120 (a) and the second wheel 120 (b) coupled to the motor spindle. In some examples, the caps 129(a), 129(b) may have threads that are screwed onto corresponding threads on the corresponding motor spindles. The caps 129(a), 129(b) may have a set depth so that the first wheel 120(a) and the second wheel 120(b) are aligned (e.g., the distance separating the farthest ends of the first wheel 120(a) and the second wheel 120(b) from the head 102 is the same). 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 coupled to a battery mounted inside the handle 104 and / or the head 102. There may be a gap 140 between the first wheel 120(a) and the second wheel 120(b) for receiving the rope 150. Along the circumference of the first wheel 120(a) and the second wheel 120(b), the first wheel 120 The first wheel 120 (a) may have a groove 122 (a), and the second wheel 120 (b) may have a groove 122 (b). The grooves 122 (a) and 122 (b) can keep the rope 150 at a set position along the first wheel 120 (a) and the second wheel 120 (b), thereby preventing the rope from being tangled. The grooves 122 (a) and 122 (b) can ensure that the rope maintains a set distance from the head 102.

[0111] The first wheel 120 (a) and the second wheel 120 (b) can be driven by at least one motor at a speed sufficient to propel the rope 150 in the air. In some examples, the first wheel 120 (a) and the second wheel 120 (b) can be driven by at least one motor running at a speed of at least about 40,000 revolutions per minute (rpm). In some examples, the at least one motor can run at a 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 more. 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 more.

[0112] The at least one motor may be equipped with a power cut-off switch. For example, the at least one motor may be in communication with a controller for controlling the operation of the at least one motor. In some examples, it is desirable to automatically (e.g., without user input) control the operation of the at least one motor. For example, if the rope 150 is between the first wheel 120 (a) and the second wheel 120 (b) winding between the at least one motor, the winding may bring strain, excessive force and / or excessive load to the at least one motor, thereby causing damage to the at least one motor. For example, when excessive force, strain and / or load are applied to the at least one motor, the at least one motor may burn out and / or generate excessive heat, thereby causing safety issues. The at least one motor may have at least one sensor, for example, a stress sensor, a current sensor or other sensor that can determine the 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 may automatically shut down the at least one motor, thereby preventing damage to the at least one motor. The threshold may be a threshold based on a percentage of the normal working load, stress and / or strain of the at least one motor. For example, the threshold may 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 working load, stress and / or strain of the at least one motor. In addition, turning off the power supply prevents the at least one motor from continuing to advance the wound rope, thereby preventing the wound rope from being damaged. The wrapped cord may be removed and untangled or replaced with a new cord, and operation of device 100 may be restored to a normal operating mode (eg, as described herein).

[0113] In at least one example, the power cut-off switch can be in communication with a controller and at least one current sensor. The threshold value can be determined by measuring the current (e.g., current) powering the at least one motor. In some examples, the current is measured in amperes. The threshold value for automatically activating the power cut-off switch and thereby turning 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 value is a measurement of the current that prevents damage to the at least one motor.

[0114] The first wheel 120(a) may have a plurality of internal fan blades 124(a), and the second wheel 120(b) may have a plurality of internal fan blades 124(b). The plurality of internal fan blades 124(a), 124(b) may 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) may draw air into the device 100 through one or more front vents 108 of the removable cover 106. Behind the first wheel 120(a) and the second wheel 120(b) may be one or more air inlets. The air inlets may allow air to be drawn into the device 100 through the internal fan blades 124(a), 124(b) and enter the interior of the device 100. When cool air from outside the device 100 is drawn into the device 100, the cool air can flow around the battery, at least one motor, and other internal components within the device 100. The cool air can cool the internal components of the device 100 and then flow out of one or more rear vents 109 of the device. In this way, the internal components of the device 100 can be cooled, thereby regulating the temperature within the device 100, maintaining stable performance, and reducing the risk of overheating. In some examples, a heat sink can be located near at least one motor and battery, and air can flow through the heat sink to remove heat from the at least one motor and battery and discharge the heat out of the one or more rear vents 109. The blade pitch of the internal fan blades 124 (a), 124 (b) can be 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 inner fan blades 124(a), 124(b) may be symmetrically spaced or asymmetrically spaced. The first wheel 120(a) and the second wheel 120(b) may have approximately 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 or more internal fan blades.

[0115] The head 102 may further include one or more connection mechanisms that can be removably coupled to one or more connection mechanisms of the removable cover 106. For example, the one or more connection mechanisms on the head 102 may include a first snap-on port 128(a) and a second snap-on port 128(b) corresponding to a first snap-on protrusion and a second snap-on protrusion on the removable cover 106. In other examples, other connection mechanisms may be used, such as magnets, latches, Velcro hook and loop fasteners, other snap-on devices, rotatable mating mechanisms, clips, and other mating / connecting mechanisms that can connect the removable cover 106 to the head 102.

[0116] The device 100 may include a lower U-shaped protrusion 126. The lower U-shaped protrusion 126 may 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 may be aligned 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 the middle of the gap 140 and in 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 may be accommodated in 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 have some longitudinal movement (e.g., toward either side of the head 102), while also preventing the cord 150 from being tangled. In some examples, the upper U-shaped protrusion 127 and the lower U-shaped protrusion 126 may be other shapes. For example, the upper U-shaped protrusion 127 and the lower U-shaped protrusion 126 may be round protrusions or square protrusions or other shapes with openings to accommodate the rope 150 so that the rope does not get tangled when being pushed by the first wheel 120 (a) and the second wheel 120 (b).

[0117] Figure 8-14 The device 100 in another example is shown. The device 100 may include a head 102 and a handle 104. The device 100 may include a removable cover 106. The removable cover 106 may include a first vent 208 (a) and a second vent 208 (b). The first vent 208 (a) and the second vent 208 (b) may each include one or more vents. The first vent 208 (a) may correspond to the first wheel 120 (a), and the second vent 208 (b) may correspond to the second wheel 120 (b). In some examples, the removable cover 106 may be made of a transparent or translucent material. In some examples, the removable cover 106 may include a transparent ultraviolet reactive material that can emit light. In some examples, the ultraviolet reactive material of the removable cover 106 may be provided with excitation light from a second ultraviolet light source (e.g., an internal ultraviolet light source), as further described herein.

[0118] In some examples, the removable cover 106 can be made of a UV-reactive material in a certain pattern. For example, different UV materials can be used to form a pattern in the removable cover. The removable cover 106 can include fluorescent and / or phosphorescent materials. In some examples, the pattern can include various graphic designs, natural patterns, objects, and any other desired designs. In some examples, the UV material of the removable cover can be provided with excitation light from a second UV light source (e.g., an internal UV light source), as further described herein.

[0119] like Figure 8 As shown, the device 100 may include a powered wheel 210 on the handle 104. The powered wheel 210 may be used to actuate the at least one motor, thereby driving (eg, rotating) the first wheel 120(a) and the second wheel 120(b). The power wheel 210 may allow finer control of the speed of the first wheel 120(a) and the second wheel 120(b) than the power switch 110 described above. The power wheel 210 may be rotated by a user to control the rotation rate of the at least one motor. For example, rotating the power wheel 210 turns on the at least one motor, and the faster the power wheel 210 rotates, the greater the power provided to the at least one motor, thereby providing a faster rotation rate to the motor spindle and the first wheel 120(a) and the second wheel 120(b).

[0120] The device 100 may further include a button 212. The button 212 may control the first ultraviolet light source 118 and the second ultraviolet light source 242, such as Figure 13-14 As shown. Button 212 may have one or more modes. In one example, button 212 may have four modes. Button 212 may repeatedly cycle through four modes by clicking button 212. For example, clicking button 212 for the first time may enter the first mode. In the first mode, the first ultraviolet light source 118 may be turned on (e.g., the first ultraviolet light source 118 begins to emit light). Clicking button 212 for the second time may enter the second mode. In the second mode, the first ultraviolet light source 118 may be turned off and the second ultraviolet light source 242 may be turned on. Clicking button 212 for the third time may enter 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 may enter 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 may be used. For example, button 212 may only have an on mode for the first click and an off mode for the second click. In another example, it is understood that the four modes may cycle through different numbers of clicks.

[0121] The device 100 may further include one or more indicator lights. Figure 8-9 As shown, the device 100 may include three indicator lights 230 (a), 230 (b), and 230 (c). (c) can indicate the battery power of the device. For example, when all three indicator lights 230(a), 230(b), and 230(c) are lit, the battery power of the device 100 is full. When only two of the three indicator lights 230(a), 230(b), and 230(c) are lit, the battery power of the device 100 is slightly reduced. When the three indicator lights 230(a), 230(b), and 230(c) are lit, the battery power of the device 100 is slightly reduced. When only one of 230(c) is illuminated, the battery charge of device 100 is low, indicating to the user that the device should be charged.

[0122] like Figure 8 As shown, the device 100 may also include an on / off indicator light 234. The on / off indicator light 234 may indicate to the user whether the device 100 is on or off. When the on / off indicator light 234 is on, the device 100 is in the on state. When the on / off indicator light 234 is off, the device 100 is in the off state. As described above, the device 100 may be turned on by actuating the power switch 110 or the power wheel 210.

[0123] like Figure 8 and Fig.10 As shown, the device 100 may also include one or more strong light lamps. In one example, The device may include a first strong light 232(a) and a second strong light 232(b) located on the head 102, such as Figure 8 As shown. Fig.10 As shown, the device 100 may further include a third highlight light 232 ( c ) and a fourth highlight light 232 ( d ) on a side of the head 102 opposite to the first highlight light 232 ( a ) and the second highlight light 232 ( b ).

[0124] like Figure 9-11 As shown, the device 100 may have one or more rear vents 209 on the rear surface of the device. In some examples, the one or more rear vents 209 may be meshed and configured to allow air to flow out of the device 100. In some examples, the one or more rear vents 209 may be part of a removable back cover that is configured to be connected to the head 102 on a side opposite the removable cover 106. The removable back cover may allow access to the interior of the device. For example, the removable back cover may use magnets, snap-on connectors, latches, Velcro, etc. Hook and loop fasteners or other attachment mechanisms may connect the removable back cover to the head 102 to be removably coupled to the head.

[0125] like Figure 13-14 As shown, the 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 the 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 luminous effect. The first ultraviolet light source 118 may have a filter, which is configured to filter the light provided by the first ultraviolet light source 118 to a wavelength of about 350nm to about 380nm, about 360nm to about 375nm or about 365nm. The filter is capable of filtering light so that it is invisible to an observer.

[0126] The second ultraviolet light source 242 may be located near the first wheel 120 ( a ) and the second wheel 120 ( b ). For example Fig.14 As shown. The second ultraviolet light source 242 may be configured to provide light to a portion of the rope 150 inside the removable cover 106. The second ultraviolet light source 242 may also provide excitation light to the removable cover 106. The second ultraviolet light source 242 may provide ultraviolet light with a wavelength of about 315nm to about 330nm, about 330nm to about 345nm, about 345nm to about 360nm, about 360nm to about 375nm, about 375nm to about 390nm, or about 390nm to about 400nm. 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 a wavelength of about 350nm to about 380nm, about 360nm to about 370nm, or about 365nm. 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 rope 150 to emit light, thereby producing a luminous effect. When the cord 150 includes phosphor, the second ultraviolet light source 242 can charge the phosphor when a portion of the cord 150 passes through the removable cover 106. After a period of time, the phosphor emits the light received from the second ultraviolet light source 242, thereby producing a luminous effect. In some examples, the first ultraviolet light source 118 and the second ultraviolet light source 242 can be 3W ultraviolet lamps.

[0127] like Fig.19As shown, the position of the first UV light source 118 can be offset from the center point of the head 102. By offsetting the first UV light source 118 from the center of the head, the light is emitted at a wider angle, thereby minimizing the area of ​​the cord 150 that is not illuminated.

[0128] like Fig.14 As shown, the head 102 may include one or more connection mechanisms configured to be removably coupled to one or more connection mechanisms of the removable cover 106. The one or more connection mechanisms on the head 102 may include a first magnet 228 (a), a second magnet 228 (b), a third magnet 228 (c), and a fourth magnet 228 (d) Fig. 20A and Fig. 20B As shown, the removable cover 106 may have corresponding connection mechanisms to removably couple to one or more connection mechanisms of the head 102 . Fig. 20B The first magnet 600 (a) and the second magnet 600 are shown. (b), the first magnet 600(a) and the second magnet 600(b) can be removably coupled to the first magnet 228(a) and the second magnet 228(b) of the head 102. Similarly, the removable cover 106 can have a third magnet and a fourth magnet, which can be removably coupled 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 removable cover 106 to the head 102 can be used to removably couple the removable cover 106 to the head 102. Removably coupling the removable cover 106 to the head 102 provides many benefits. For example, if the cord 150 is wrapped inside the removable cover 106, the user can easily remove the cover and untie the cord 150.

[0129] Fig.16The 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 be coupled 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 so that the cap 129 (a) is screwed onto corresponding threads of the first motor spindle 300 (a), or other connection mechanisms that can couple the cap 129 (a) to the first motor spindle 300 (a) are used. The cap 129 (b) of the second wheel 120 (b) can be configured to be coupled to 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 so that the cap 129(b) is screwed onto corresponding threads of the second motor spindle 300(b), or other connection mechanisms that can couple the cap 129(b) to the second motor spindle 300(b) are used. 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), thereby being rotatably mounted to the head 102.

[0130] The first motor spindle 300(a) and the second motor spindle 300(b) may 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 may be configured to rotate the first motor spindle 300(a) and the second motor spindle 300(b), thereby rotating the first wheel 120(a) and the second wheel 120(b). In another example, the first motor spindle 300(a) and the second motor spindle 300(b) may be coupled to one motor. The one motor may rotate the first motor spindle 300(a) and the second motor spindle 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) may rotate in opposite directions. For example, the first wheel 120(a) may rotate counterclockwise and the second wheel 120(b) may rotate clockwise, or vice versa.

[0131] like Fig.16 and Fig.18 As shown, the device 100 may also include an air inlet that can receive air drawn 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(d) for allowing air to enter the interior of the device 100. (d), 304(a), 304(b).

[0132] like Figure 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 accommodate a first motor that rotates the first wheel 120(a). The second cavity may be used to accommodate a second motor that rotates the second wheel 120(b). In another example, the head 102 may include a single cavity for accommodating 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).

[0133] like Fig.18 As shown, the head 102 may also include an aluminum circuit board 502. The 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 welded 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 welded to the aluminum circuit board 502. The aluminum circuit board 502 may act as a heat sink, absorbing the 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 different materials known in the art that can be used as a heat sink.

[0134] like Figure 15-18 As shown, the 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 or the first vents 208 (a) and the second vents 208 (b) of the removable cover 106, an aluminum circuit board 502, an air inlet 302 102 (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 the motor, the internal fan blades 124 (a), 124 (b) draw air in through one or more front vents 108 or the first vent 208 (a) and the second vent 208 (b). The air flows through the air inlets 302 (a), 302 (b), 302 (c), 302 (d), 304 (a), 304 (b) of the head 102 and flows into the interior of the head 102. As the first wheel 120 (a) and the second wheel 120 (b) are continuously driven, air is continuously drawn into the head 102. The air is then able to flow through the motor and the aluminum circuit board 502 and take away heat from the motor and the aluminum circuit board 502. Air may be exhausted from the head 102 of the device 100 at the one or more rear vents 109 or the one or more rear vents 209 .

[0135] Fig.17 Airflow paths are shown. Air can flow along a first airflow path 402, a second airflow path 404, and a third airflow path 406. Air can enter the device through the air inlets 302 (a), 302 (c), flow around the upper surface of the first motor 400 and the second motor (not shown), and then be discharged from one or more rear vents 109 or one or more rear vents 209 in the first airflow path 402. The first airflow path 402 can also take away heat from the aluminum circuit board 502 from one or more rear vents 209. In the second airflow path 404, air can flow through the air inlets 304 (a), 304 (b) around the first motor 400 and the second motor (not shown), and then be discharged from one or more rear vents 109 or one or more rear vents 209. In the third airflow path 406, air can flow through the air inlets 302 (b), 302 (d) and flow around the lower surface of the first motor 400 and the second motor (not shown), and then be discharged from one or more rear vents 109 or one or more rear vents 209. In this way, the motors, UV light source, and other internal components of device 100 can be maintained at a regulated operating temperature, thereby extending battery life and preventing overheating of device 100. In some examples, the cooling system can further include one or more heat sinks proximate to the one or more motors, and air can be passed through the heat sinks to further cool the one or more motors.

[0136] Figure 21-23 A rope 150 is shown. The rope 150 may be Figure 22-23The looped rope shown. Rope 150 may include a blend of cotton and polyester materials. The polyester may 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 may reduce the weight of the rope and provide sufficient friction and surface texture to be pushed into the air, thereby creating a levitation effect. Fig.21 As shown, the cord 150 may have a first end and a second end that are permanently joined at a connection point 700. Figure 21-23 1 and 12. The connection point 700 is shown in FIG. 1 , but is not visible to the human eye and has approximately the same diameter as the rope 150. The connection point is seamless, thereby preventing the rope 150 from rattling or bouncing when it is pushed by the first wheel 120(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.

[0137] The rope 150 may have two ends, a first end 702 and a second end 704. Both ends of the rope may be placed into a mold. The mold can be configured so that heat is transferred to the inside of the mold, but the mold does not melt or otherwise change shape. Heat can be provided to the mold 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 keep the shape of rope 150 so that the connection point 700 has the same diameter or substantially the same diameter as the rest of the rope. Once the polyester in the first end 702 and the second end 704 melts 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, when the first end 702 and the second end 704 are melted in the mold, force or pressure can be applied to form a connection point 700 having a desired diameter (e.g., approximately equal to the diameter of the other parts of the rope). In this way, the first end 702 and the second end 704 form a seamless connection and form an endless rope.

[0138] 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 at a maximum diameter of about 0.5 mm to about 0.6 mm. 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 mm, thereby preventing any rattling caused by the connection point when the device 100 propels the rope in the air. In addition, maintaining the diameter of the connection point 700 below the diameter of the gap 140 can stabilize the movement of the rope 150 in the air and prevent any rebound or unnecessary movement of the rope 150. Exemplary systems and methods for forming the rope 150 will be further described herein.

[0139] like Figure 22-23 As shown, the rope 150 may include a plurality of ropes. Fig. 22 As shown, the rope 150 may include a first rope 802 and a second rope 806. The first rope 802 may have two ends, namely a first end and a second end. The first end and the second end of the first rope 802 may be permanently joined to the first end and the second end of the second rope 806 at connection points 800 and 804 using the rope connection method described herein. Fig.23 As shown, the rope may 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 may be permanently joined at connection points 800, 804, 808 using the rope connection systems and methods described herein.

[0140] 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, and different colors can be emitted when ultraviolet irradiation. When the first ultraviolet light source 118 and / or the second ultraviolet light source 242 provide light for the rope, the rope can emit light of different colors, thereby producing a flickering visual effect when propelling in the air. To the observer, this flickering visual effect is like the instantaneous color conversion of the rope. Similarly, the first rope 802, the second rope 806 and the third rope 810 can be dyed with fluorescent dyes, and different colors can be emitted when ultraviolet irradiation. In some examples, 4, 5, 6, 7, 8, 9, 10 or more different ropes can be connected using the rope connection system and method described herein, and all ropes or part of the ropes can include ultraviolet reactive materials.

[0141] 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 the portion of the rope 150 in the removable cover 106, and then the rope can emit light. Similar to a fluorescent rope, a phosphorescent rope can be combined with different luminous colors, and multiple ropes can be used. In some examples, the phosphorescent light passes through the second ultraviolet light source 242 in the removable cover 106, and the phosphorescent light in the rope 150 is charged. The phosphorescent light can have a delayed luminescence time, so that once the phosphorescent light in the rope 150 is outside the removable cover 106, the phosphorescent light begins to emit light. In this way, the visual illumination of the phosphorescent light 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 phosphor within the removable cover 106 via the second UV light source 242, an observer may be surprised that the cord 150 does not glow when entering the removable cover 106, but glows when leaving the removable cover 106. In addition, by charging the phosphor via the second UV light source 242, a visual effect can be achieved in low light conditions without requiring the first UV light source 118 to provide excitation light (e.g., the first UV light source 118 is turned off or not included in the device 100).

[0142] In some examples, after the second UV light source 242 is turned off, the phosphor in the rope 150 is still charged by the excitation light and continues to glow. In this way, when the first UV light source 118 or the second UV light source 242 does not provide excitation light, the observer may be surprised by the continued glow of the rope 150.

[0143] In some examples, the looped rope may include multiple ropes, each rope having a different UV reactive material that emits light in a different color. For example, the multiple ropes may 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.

[0144] like Figure 1 and Fig.12 As shown in the figure, rope 150 can be connected to device 100. As described herein, rope 150 is connected to device using gap 140 between first wheel 120 (a) and second wheel 120 (b), upper U-shaped protrusion 127 and lower U-shaped protrusion 126 and removable cover 106. When rope 150 is connected to the device, rope 150 can be pushed in the air and looks suspended. The speed at which rope 150 is pushed by first wheel 120 (a) and second wheel 120 (b) can make rope 150 suspended in the air. The user can move the handle 104 in the hand to make different shapes and patterns with rope 150. In addition, the fluorescent dye used on the rope can provide a flashing color effect, so that rope 150 looks instantly discolored.

[0145] A rope propulsion kit is also provided herein.A rope propulsion kit may include one or more looped ropes as described herein, any device as described herein, and packaging.

[0146] Figures 25A-25F A system 2500 for forming a rope as described herein is shown. The system 2500 can form a single continuous rope from two or more ropes, and / or form a looped rope from a single rope or two or more ropes. For example, the system 2500 can receive the two ends of one or more ropes and connect the ends of one or more ropes. The system 2500 heats the ends, thereby melting the ends and then connecting the ends. Then, the system 2500 can move the melted ends together so that the ends are in contact in a mold or other mechanism. Then, the system 2500 can provide a compressive force to the ends, thereby connecting the melted ends and forming a single rope. In some examples, the melted ends are connected at a connection point. The connection point can have a diameter roughly the same as the rest of the rope, so that the entire rope has a consistent and uniform diameter.

[0147] like Figures 25A-25F As shown, the system 2500 may include a first tether retention mechanism 2506, a second tether retention mechanism 2516, a drive arm 2508, a compression mechanism 2514, a base 2502, and at least one heating device (e.g., a first heating device 2512(a)). Fig.25A A first rope 2504 is shown fixed in a first rope holding mechanism 2506. Each of the first rope holding mechanism 2506 and the second rope holding mechanism 2516 can fix a rope within the system 2500. The first rope holding mechanism 2506 and the second rope holding mechanism 2516 can each fix a rope so that one end of each rope extends outside 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 fixing the rope so 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 fixing the rope so 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 clamps or other mechanisms for fixing ropes.

[0148] Fig.25BA close-up view of system 2500 is shown. As shown, first rope holding mechanism 2506 may include first holding mechanism upper portion 2526 and first holding mechanism lower portion 2524. First holding mechanism upper portion 2526 and / or first holding mechanism lower portion 2524 can move vertically within system 2500. For example, first holding mechanism upper portion 2526 can move vertically upward or downward. Similarly, first holding mechanism lower portion 2524 can move vertically upward or downward. When the rope is placed between first holding mechanism upper portion 2526 and first holding mechanism lower portion 2524, first holding mechanism upper portion 2526 and / or first holding mechanism lower portion 2524 are moved so that first holding mechanism upper portion 2526 contacts first holding mechanism lower portion 2524 and the rope is fixed therein. In some examples, first holding mechanism lower portion 2524 is not vertically movable.

[0149] The second rope holding mechanism 2516 may 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 move vertically within the system. For example, the second holding mechanism upper portion 2528 can move vertically upward or downward. Similarly, the second holding mechanism lower portion 2530 can move vertically upward or downward. When the 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 fixed therein. In some examples, the second holding mechanism lower portion 2530 is not vertically movable.

[0150] System 2500 may include at least one heating device. The at least one heating device may 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, the temperature of which reaches or exceeds the melting point of one or more ropes, so that the ends of the ropes are melted by the at least one heating device. The at least one heating device may be located between the first rope holding mechanism 2506 and the second rope holding mechanism 2516, so that heat can be provided to both ends of a single rope or the ends of the first rope and the ends of the second rope, thereby melting. In some examples, the system may include a first heating device 2512 (a) and a second heating device 2512 (b). The first heating device 2512 (a) may provide heat to the ends of the ropes fixed in the second rope holding mechanism 2516. The second heating device 2512 (b) may provide heat to the ends of the ropes fixed in the first rope holding mechanism 2506.

[0151] The system may include a compression mechanism 2514. The compression mechanism 2514 may provide pressure or force to the melted ends of the rope, thereby combining the ends of the two ropes to form a single continuous rope. In some examples, the compression mechanism 2514 may include a mold within the compression mechanism. For example, the two melted ends to be combined may be placed in a mold portion, and then pressure or force may be provided by the compression mechanism 2514 to form a continuous rope. In some examples, the mold may have substantially the same diameter as the rope, so that when the melted ends are combined, the single continuous rope has a consistent and uniform diameter.

[0152] 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 cord holding mechanism 2506 and the second cord holding mechanism 2516. In some examples, the compression mechanism 2514 can also be a heating device, such that at least one heating device and the compression mechanism 2514 are the same component. When at least one heating device and the compression mechanism 2514 are the same component, the compression mechanism 2514 can be located between the first cord holding mechanism 2506 and the second cord holding mechanism 2516.

[0153] like Figures 25A-25F As shown, the compression mechanism 2514 may include an upper compression component 2520 and a lower compression component 2522. The upper compression component 2520 and the lower compression component 2522 may connect the melted ends of one or more ropes. For example, the upper compression component 2520 and the lower compression component 2522 may provide pressure or force to the melted ends of one or more ropes to form a continuous rope. In some examples, the upper compression component 2520 and / or the lower compression component 2522 may be vertically movable. For example, the upper compression component 2520 may be moved upward or downward within the system 2500. Similarly, the lower compression component 2522 may be moved upward or downward within the system 2500. In some examples, the lower compression component 2522 is vertically fixed within the system 2500 (e.g., the lower compression component 2522 may not be vertically movable within the system 2500).

[0154] like Figures 25A-25FAs shown, in some examples, the upper compression member 2520 and the lower compression member 2522 can be a V-shaped fixture (e.g., a V-shaped mold). In some examples, when the upper compression member 2520 and the lower compression member 2522 contact each other, the upper compression member 2520 and the lower compression member 2522 can form a mold. In some examples, the melted ends of one or more ropes can be loaded into the V-shaped portion of the lower compression member 2522. Once the melted ends are loaded into the V-shaped portion of the lower compression member 2522, the upper compression member 2520 can move downward, thereby providing a force or pressure to connect the melted ends. In some examples, the V-shaped portion of the lower compression member 2522 has a channel at the bottom of the V (e.g., the portion of the V-shaped farthest from the upper compression member 2520). In some examples, the channel has a diameter that is approximately the same as the diameter of the one or more ropes, so that when the force or pressure is provided by the upper compression member 2520, the melted ends are connected, thereby forming a single rope with a substantially uniform and consistent diameter.

[0155] In some examples, upper compression member 2520 and lower compression member 2522 may each be disposed on a contact surface (eg, The upper compression member 2520 has a semicircular mold on its surface that contacts the surface of the lower compression member 2522. The melted ends of one or more ropes can be loaded into the semicircular mold of the lower compression member 2522 so that when the upper compression member 2520 moves into contact with the lower compression member 2522, the melted ends are combined to form a single rope. In some examples, the diameter formed by the semicircular combination is equal to the diameter of one or more strings, so that the melted ends are connected to have approximately the same diameter as one or more ropes.

[0156] Fig.25C The system 2500 is shown in a loading position. In the loading position, the first holding mechanism upper portion 2526 can be in a vertically raised position (e.g., the first holding mechanism upper portion 2526 is not in contact with the first holding mechanism lower portion 2524). The first rope 2504 can be loaded into the first rope holding mechanism 2506 by placing the first rope 2504 on the first holding mechanism lower portion 2524. Fig.25CAs shown, the first cord 2504 may have an end 2538 extending from the first cord holding mechanism 2506 toward the second heating device 2512 (b), thereby allowing the end 2538 to be provided with heat by the second heating device 2512 (b). Once the first cord 2504 is properly positioned (e.g., the end 2538 extends longitudinally outward from the first cord holding mechanism 2506 toward the second heating device 2512 (b)), the first holding mechanism upper portion 2526 may be vertically lowered to contact the first holding mechanism lower portion 2524, as shown by arrow 2536. In some examples, the first holding mechanism upper portion 2526 may be slidably coupled to a guide rail that may allow the first holding mechanism upper portion 2526 to move vertically. In some examples, the first holding mechanism upper portion 2526 may be manually slid or moved along the guide rail by an operator to contact the first holding mechanism lower portion 2524. In some examples, the first holding mechanism upper portion 2526 may be vertically positioned along the guide rail by a motor or actuator that communicates with the controller. In some examples, the first retaining mechanism upper portion 2526 may have a fixing mechanism (e.g., a snap-on mechanism, a magnetic mechanism, etc.) for fixing the first retaining mechanism upper portion 2526 to a corresponding fixing mechanism of the first retaining mechanism lower portion 2524, thereby fixing the first rope 2504 within the first rope retaining mechanism 2506.

[0157] In the loading position, the second holding mechanism upper portion 2528 can be in a vertically raised position (e.g., the second holding mechanism upper portion 2528 is not in contact with the second holding mechanism lower portion 2530). The second rope 2532 can be loaded into the second rope holding mechanism 2516 by placing the second rope 2532 on the second holding mechanism lower portion 2530. Fig.25CAs shown, the second cord 2532 may have an end 2540 extending from the second cord holding mechanism 2516 toward the first heating device 2512 (a), thereby allowing the end 2540 to be provided with heat by the first heating device 2512 (a). Once the second cord 2532 is properly positioned (e.g., having an end 2540 extending longitudinally outward from the second cord holding mechanism 2516 toward the first heating device 2512 (a)), the second holding mechanism upper portion 2528 may be vertically lowered to contact the second holding mechanism lower portion 2530, as shown by arrow 2534. In some examples, the second holding mechanism upper portion 2528 may be slidably coupled to a guide rail that may allow the second holding mechanism upper portion 2528 to move vertically. In some examples, the second holding mechanism upper portion 2528 may be manually slid or moved along the guide rail by an operator to contact the second holding mechanism lower portion 2530. In some examples, the second holding mechanism upper portion 2528 may be vertically positioned along the guide rail by a motor or actuator that communicates with the controller. In some examples, the second retaining mechanism upper portion 2528 may have a fixing mechanism (e.g., a snap-on mechanism, a magnetic mechanism, etc.) for fixing the second retaining mechanism upper portion 2528 to a corresponding fixing mechanism of the second retaining mechanism lower portion 2530, thereby fixing the second rope 2532 within the second rope retaining mechanism 2516.

[0158] Fig.25D The system 2500 is shown in a heating position. In the heating position, the first rope holding mechanism 2506 moves longitudinally toward the second heating device 2512 (b) together with the fixed first rope 2504 so that the end 2538 of the first rope 2504 is aligned with the second heating device 2512 (b). In some examples, the first rope holding mechanism 2506 is slidably coupled to the guide rail so that the first rope holding mechanism 2506 can be moved longitudinally in the system 2500. In some examples, other mechanisms can be used to enable the first rope holding mechanism 2506 to move longitudinally in the system 2500. In some examples, the operator can manually move the first rope holding mechanism 2506 toward the second heating device 2512 (b) to align the end 2538 with the second heating device 2512 (b). In some examples, the first rope holding mechanism 2506 can be moved toward the second heating device 2512 (b) via a motor or actuator that communicates with a controller. Once the end 2538 of the first rope 2504 is aligned with the second heating device 2512 ( b ), the second heating device 2512 ( b ) may provide heat (e.g., heated air or gas) to the end 2538 , thereby melting the material at the end 2538 of the first rope 2504 .

[0159] Similarly, in Fig.25DIn the heating position shown, the second rope holding mechanism 2516 moves longitudinally toward the first heating device 2512 (a) together with the fixed second rope 2532 so that the end 2540 of the second rope 2532 is aligned with the first heating device 2512 (a). In some examples, the second rope holding mechanism 2516 is slidably coupled to the guide rail so that the second rope holding mechanism 2516 can be moved longitudinally in the system 2500. In some examples, other mechanisms can be used to enable the second rope holding mechanism 2516 to move longitudinally in the system 2500. In some examples, the operator can manually move the second rope 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 rope holding mechanism 2516 can be moved toward the first heating device 2512 (a) via a motor or actuator that communicates with the controller. Once the end 2540 of the second rope 2532 is aligned with the first heating device 2512 ( a ), the first heating device 2512 ( a ) may provide heat (e.g., heated air or gas) to the end 2540 , thereby melting the material at the end 2540 of the second rope 2532 .

[0160] The first heating device 2512 (a) and the second heating device 2512 (b) may be controlled by a controller (e.g., The controller may 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) may provide heat at a temperature sufficient to melt the first rope 2504 and / or the second rope 2532. In some examples, the temperature may 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 may depend on the material of the rope to be melted. The temperature may be between the melting point and the ignition point of the rope material to be melted.

[0161] Fig.25E The compression mechanism loading position of the system 2500 is shown. In the compression mechanism loading position, the end 2538 of the first rope 2504 is loaded into the lower compression member 2522 of the compression mechanism 2514. The end 2538 can be loaded into the lower compression member 2522 of the compression mechanism 2514 by moving the first rope retaining mechanism 2506 in the direction of the compression mechanism 2514. As described herein, the first rope retaining mechanism 2506 can be moved longitudinally throughout the system 2500. Arrow 2542 shows the movement of the first rope retaining mechanism 2506 in the compression mechanism loading position.

[0162] In the compression mechanism loading position, the end 2540 of the second rope 2532 is loaded into the lower compression member 2522 of the compression mechanism 2514. The end 2540 can be loaded into the lower compression member 2522 of the compression mechanism 2514 by moving the second rope retaining mechanism 2516 toward the compression mechanism 2514. As described herein, the second rope retaining mechanism 2516 is able to move longitudinally throughout the system 2500. Arrow 2544 shows the movement of the second rope retaining mechanism 2516 in the compression mechanism loading position. In some examples, the end 2538 of the first rope 2504 and the end 2540 of the second rope 2532 are loaded into the lower compression member 2522 so that the end 2538 contacts the end 2540. In some examples, the end 2538 and the end 2540 are loaded in the lower compression member 2522 so that the end 2538 and the end 2540 overlap each other.

[0163] Fig.25F The forming position of the system 2500 is shown. In the forming position, the upper compression member 2520 is driven downward toward the lower compression member 2522. The upper compression member 2520 can be coupled to the drive arm 2508. The drive arm 2508 can drive the upper compression member 2520 downward to contact the lower compression member 2522, thereby providing pressure or force to the ends 2538, 2540 of the first rope 2504 and the second rope 2532. Arrow 2546 shows the movement of the drive arm 2508 in the forming position. In some examples, when the ends 2538, 2540 have melted, the pressure or force provided to the ends 2538, 2540 by the upper compression member 2520 causes the ends 2538, 2540 to connect to each other. As described herein, the ends 2538, 2540 can be connected by force or pressure so that the ends 2538, 2540 form a consistent and uniform diameter with the first rope 2504 and the second rope 2532. In this manner, the first cord 2504 and the second cord 2532 are connected and have uniform and consistent diameters. In some examples, the pressure or force provided by the upper compression member 2520 and the drive arm 2508 is controlled by a controller through user input (eg, the user inputs the pressure or force to be applied).

[0164] In some examples, the system 2500 may further include one or more fans. The one or more fans may cool the ends 2538, 2540 after the ends 2538, 2540 of the first rope 2504 and the second rope 2532 are connected. For example, the one or more fans may provide cool air to the ends 2538, 2540, thereby cooling the ends 2538, 2540.

[0165] The present invention also provides a method for manufacturing a looped rope. Fig.24Method 2400 is shown. Method 2400 can start at block 2402. At block 2402, method 2400 can include providing one or more ropes. In some examples, the ropes 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 ropes include 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or more ropes.The rope may comprise a mixture of cotton material and polyester material.

[0166] At block 2404, method 2400 includes placing the ends of one or more ropes in a mold. The mold can be configured to transfer heat to the interior of the mold without melting or otherwise changing shape. In some examples, only the two ends are placed in a single heat-resistant mold. Multiple molds can be provided to connect multiple ropes. The mold can have a diameter of about 0.1 mm to about 1 mm, or about 0.5 mm to about 0.6 mm.

[0167] At block 2406, method 2400 may include providing heat to the mold to melt the polyester material in the ends of the one or more ropes. In some examples, the heat may 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.

[0168] At block 2408, method 2400 may include cooling the mold. The mold is cooled to allow the polyester ends of one or more ropes to be permanently connected together at a diameter defined by the mold. In some examples, the diameter of the connected end is the same or substantially the same as the diameter of the rest of the one or more ropes. In some examples, method 2400 may be repeated to connect multiple ropes until a looped rope comprising multiple ropes is formed.

[0169] Also provided herein is a method 2600 for making the rope described herein. Fig.26 The method 2600 is shown. In some examples, the method 2600 can form a continuous looped rope including multiple segments having different materials (eg, different fluorophores, phosphors, and / or colors).

[0170] At block 2602, method 2600 may 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 may extend longitudinally out of the first rope holding mechanism, and a second end of the second rope segment may extend longitudinally out of the second rope holding mechanism. In some examples, method 2600 may include securing the first rope segment to the first rope holding mechanism so that the first rope segment does not move relative to the first rope holding mechanism. In some examples, the first rope holding mechanism may be a clamp or other mechanism that may secure the first rope segment. In some examples, method 2600 may include securing the second rope segment to the second rope holding mechanism so that the second rope segment does not move relative to the second rope holding mechanism. In some examples, the second rope loading mechanism may be a clamp or other mechanism that may secure the second rope segment.

[0171] At block 2604, method 2600 may include heating a first end of a first rope segment and a second end of a second rope segment, Thereby melting the first end and the second end. In some examples, in order to heat the first end and the second end, the first rope holding mechanism and the second rope holding mechanism are longitudinally translated so 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 may 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 may depend on the material of the rope to be melted. The temperature may be between the melting point and the burning point of the rope material to be melted. In some examples, the at least one heating device may include a first heating device for heating the first end and a second heating device for heating the second end.

[0172] At block 2606, method 2600 may include contacting the first end of the first rope segment with the second end of the second rope segment. Contacting the first end and the second end may include moving, translating and / or sliding the first rope holding mechanism and the second rope holding mechanism to bring them close. 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 may 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 may include an upper compression part and a lower compression part. The melted end may be received in the lower compression part. In some examples, the lower compression part and the upper compression part may each form half of a mold or a channel that can connect the melted ends and form a diameter consistent with the first rope segment and the second rope segment.

[0173] At block 2608, method 2600 may 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 may be provided by a compression mechanism (e.g., an upper compression member may move downward to contact a lower compression member, 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 may form a diameter defined by a mold or channel. In some examples, the molded diameters of the first end and the second end are substantially equal to the diameters of the first rope segment and the second rope segment, thereby forming a continuous rope with a consistent and uniform diameter.

[0174] In some examples, method 2600 may include cooling the connected first and second ends. Cooling the connected first and second ends may include providing cool air via one or more fans or allowing the connected first and second ends to cool at room temperature.

[0175] In some examples, method 2600 can be repeated multiple times to connect multiple rope segments together. In some examples, method 2600 is completed when one end of the continuous rope (including multiple segments) is connected to the other end of the continuous rope, and a looped rope is formed.
