FIELD OF THE INVENTION

This invention relates to a launched zipline amusement ride.

BACKGROUND

A zipline amusement ride typically consists of a rolling trolley or bogie suspended on an inclined cableway, designed to enable a user propelled by gravity to travel from the top to the bottom of the cableway by holding on to, or attaching to, the freely moving trolley or bogie. Zipline rides may be short and low, intended for child's play and may be found on some playgrounds. Longer and higher versions are often installed for a more thrilling, high speed ride.

Zipline rides are typically designed so that the rider is transported to, or independently makes his or her way to, the top of the cableway to commence the ride. These rides typically follow a substantially downward path on a selected catenary arc from a high point to a low point, generally building speed through the downward section of the cableway until a braking zone is reached at or near the low point. In the braking zone the cable may follow a substantially horizontal or upward course to facilitate braking. The selection of the catenary arc is important as a cableway with insufficient tension may result in excessive sag, exacerbated by the weight of the descending rider(s) which creates a progressive triangulation effect on the cableway, with the consequence that the last portion of the cableway may become too steep to allow the rider(s) to complete the course through momentum.

Although powered zipline bogies and towed bogies which may transport riders horizontally or uphill are known in the art, these rides typically do not provide the thrill of rapid acceleration at the commencement of the ride. US 2002/0162477 A1 (Palumbo) is an example of a relatively high speed zipline ride where the riders ascend a dual cable cableway in a harness or tram by means of a driven cable extending the length of the cableway. Palumbo also incorporates various known mechanical deceleration and braking configurations. US 9145148 (Tilley) is an example of a relatively high speed zipline ride where the riders may traverse a cableway by means of a motorised trolley. Tilley also describes an additional feature whereby the zipline course includes segments of rail at various points on the course to enable the trolley to transition from cable to rail to cable in order to change direction horizontally or vertically without disembarking from the cableway.

A further problem in zipline rides is the control of the braking of the rider. Whilst an uphill section of the cableway can be utilized in a braking zone to facilitate braking by slowing the momentum of the incoming rider, this will usually be insufficient of itself to bring the rider to a complete stop and so is usually accompanied by a spring bank, tyre bank, bungy cord arrest system or similar braking means known in the art. Alternatively, a braking stop on the cableway can be used to ensure the rider comes to a complete stop in the braking zone. However, all of these systems can result in a large impact experienced by riders when the riders enter the braking zone with significant momentum.

It is therefore an object of at least an embodiment the present invention to provide a launched zipline amusement ride which enables a rider to be propelled along a track line, optionally from a lower point of the track line toward a higher point of the track line. An additional or alternative object of at least an embodiment the present invention is to provide a braking system for zipline amusement rides which reduces the impact within braking zones. An additional or alternative object is to at least provide the public with a useful alternative.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

Figure 1 shows a launched zipline amusement ride. The ride comprises a track line 100, a carrier 200 for carrying a rider 202, and a launch mechanism 300. The track line 100 comprises a suspended tensioned cable 102. The carrier 200 comprises a carrier trolley 204 adapted to move along the track line 100. The launch mechanism 300 is arranged to engage with the carrier 200 between an engagement position 302 and a release position 304 to accelerate the carrier 200 in a first direction 210 along the track line 100, and to disengage from the carrier 200 at the release position 304 to propel the carrier 200 along the track line 100 in the first direction 210.

In the configuration shown, the launch mechanism 100 comprises a launch dolly 328. The launch dolly 304 is arranged to engage with the carrier trolley 204 between the engagement position 302 and the release position 304 to accelerate the carrier 200 in the first direction 210 along the track line 100, and to disengage from the carrier trolley 204 at the release position 304 to propel the carrier 200 along the track line 100 in the first direction 210.

Figures 2 to 4 illustrate operation of the launched zipline amusement ride in greater detail. Figure 2 shows the carrier 200 and launch mechanism 300 in an initial position, before the ride has commenced. A rider may enter the carrier 200 while the carrier 200 is in the initial position. Once the rider is secured in the carrier 200, the launch mechanism 300 engages with the carrier 200 to accelerate the carrier 200 in the first direction 210.

When a launch dolly 328 is used, the launch dolly 328 engages with the carrier trolley 204 to accelerate the carrier 200 in the first direction 210.

Figure 3 shows the carrier 200 being accelerated by the launch mechanism 300. The launch mechanism 300 disengages from the carrier 200 at the release position 304 to propel the carrier 200. Figure 4 shows the carrier 200 and launch mechanism 300 just after disengagement of the launch mechanism 300 from the carrier 200 at the release position 304.

When a launch dolly 328 is used, the launch dolly 328 disengages from the carrier trolley 204 at the release position 304 to propel the carrier 200.

In the embodiment of figures 1 -4, the launch mechanism 300 engages with the carrier 200 at the start of the ride. In alternative embodiments, the launch mechanism 300 may engage with the carrier 200 at any suitable point during the ride. For example, the ride could commence under gravity or with a different launch mechanism and the launch mechanism 300 could engage with the carrier 200 part-way along the ride.

Track line

Referring to figure 1, in the illustrated embodiment the track line 100 is inclined in a generally upwards direction from a lower point 104 proximal to the release position 304 to a higher point 106 distal from the release position 304, such that the carrier 200 is propelled by the launch mechanism 300 toward the higher point 106 against the force of gravity.

The lower point 104 is relatively lower than the higher point 106. The lower point 104 may be the lowest point of the track line 100, or may be a point on the track line 100 that is lower than the higher point 106 but might not be the lowest point of the track line 100.

The higher point 106 is relatively higher than the lower point 104. The higher point 106 may be the highest point of the track line 100, or may be a point on the track line 100 that is higher than the lower point 104 but might not be the highest point of the track line 100.

In alternative embodiments the track line 100 might not be inclined in a generally upwards direction. For example, the track line 100 may extend between two points that are at about the same height. Alternatively, the track line 100 may be inclined in a generally downwards direction from a higher point proximal to the release position 304 to a lower point distal from the release position 304, such that acceleration of the carrier 200 toward the lower point is assisted by the force of gravity. Such an arrangement may provide a rider with a more exhilarating ride than solely relying on acceleration provided by the force of gravity.

In alternative embodiments, the track line 100 may comprise a substantially rigid launch zone 103 wherein the carrier 200 is propelled in the launch zone 103 toward the release position 304 to intersect with the suspended cable 102 following the initial propulsion from the launch mechanism 300. An exemplary configuration is shown in Figure 16.

The launch zone 103 could comprise any suitable material or form such as steel pipe or rail and may be supported from the ground by posts or any suitable support structure.

Additionally, or alternatively, the track line 100 may comprise one or more sections 105 wherein the trolley 200 transitions from the suspended, tensioned cable 102 to a rigid rail 105', and/or vice versa, to facilitate a directional change either horizontally or vertically or both to another section of cableway. Again, an exemplary configuration is shown in Figure 16.

The configuration of Figure 16 may have any of the features described herein, and like reference numerals indicate like parts to Figure 1.

Carrier

The carrier 200 may be any suitable carrier for safely carrying a rider 202 on the ride. The carrier 200 comprises a rider restraint 212 for securing a rider 202 in the carrier 200. In the embodiment of figures 1 -4, the rider restraint 212 is suspended below the carrier trolley 204. In alternative embodiments, the rider restraint 212 may be positioned above the carrier trolley 204, as discussed in more detail in relation to figure 15 below. The rider restraint 212 may take any suitable form. For example, the rider restraint 212 may be a conventional fabric harness commonly used for known zipline rides. Alternatively, the rider restraint 212 may be a rigid structure, for example providing a seat for the rider to sit on.

In the configuration shown, the carrier 200 is configured to support the rider in a forwardfacing upright seated orientation. In alternative configurations, the carrier may be configured to support the rider in other orientations, such as forward- or rearward-facing prone orientations, either upwardly- or downwardly- facing for example.

In some embodiments, the rider restraint 212 is rotatable relative to the carrier trolley 204. In the illustrated embodiment, the rider restraint 212 is rotatable about a substantially horizontal axis such that the rider restraint 212 can rock forwards and backwards relative to the carrier trolley 204. In other embodiments, the rider restraint 212 is rotatable about a substantially vertical axis relative to the carrier trolley 204, such that the rider restraint 212 can turn around relative to the carrier trolley 204 to allow the rider 202 to face in a different direction.

The carrier 200 is made of materials that are suitably weather resistant; for example, a galvanised steel frame and vinyl seats.

In some embodiments, the carrier 200 may be adapted to carry a single rider 202. In other embodiments, the carrier 200 may be adapted to carry any desired number of riders, such as two, three or four riders.

Launch mechanism

Referring to figures 2-4, the launch mechanism 300 comprises a driven, elongate member 306, such as a cable, conveyor, or belt. The elongate member 306 could be any suitable material such as steel or ultra-high-molecular-weight polyethylene. The elongate member 306 extends between first and second pulleys 308, 310 of a pulley system. The pulleys 308, 310 are rotatably supported by suitable bearings (not shown).

The launch mechanism 300 is arranged to propel the carrier 200 in an upward trajectory from the release position 304 with sufficient force to overcome resistant forces (including gravity, drag and rolling resistance) acting on the carrier 200, carrier trolley 204, rider restraint 212 and rider(s) 202 so that they ascend the track line 100 to a position at, near, or toward the higher point 106. The higher point 106 can be any suitable distance from the release position 304 and any suitable height above the release position 304.

The launch mechanism 300 comprises an energy source 312 that is operatively connected to the elongate member 306 to drive the elongate member 306. Any suitable energy source 312 may be used. In an exemplary embodiment, the energy source 312 comprises an electric motor controlled by a controller. Alternatively, the energy source 312 may be an internal combustion motor, linear induction motor, hydraulic motor or any other suitable energy source. The launch mechanism 300 may also comprise a battery bank or other means (not illustrated) to store energy generated by the energy source 312 or sourced from a power grid or other external source. The stored energy may be released on activation of the launch mechanism 300.

In the illustrated embodiment, the energy source 312 is an electric motor which is coupled to a gearbox 314 via a gearbox shaft 316. The gearbox 314 is operatively connected to a known selective energy transfer mechanism 318 which may be a mechanical clutch. The selective energy transfer mechanism 318 is operable to transfer energy from the gearbox 314 to a third pulley 320 of the pulley system via a pulley shaft 322. The third pulley 320 is operatively connected to the first pulley 308, for example via a suitable cable, conveyor, or belt 323, to transfer energy to the elongate member 306 to accelerate the carrier 200 in the first direction 210. The pulley shaft 322 is rotatably supported by suitable bearings 324.

It will be appreciated that in an alternative embodiment the electric motor may be more directly connected to the pulley system without the need for either of the energy transfer mechanism or the gearbox

It will be appreciated that the arrangement described above is an example of one way in which energy may be provided to the elongate member 306, and other possible means for providing energy to the elongate member 306 would be apparent to a skilled person.

The elongate member 306 is releasably coupled to the carrier 200. In the embodiment shown, the launch mechanism 300 comprises a launch dolly 328 operatively connected to the driven elongate member 306 and arranged to push the carrier trolley 204 along the track line 100 in the first direction 210. In the embodiment of figures 1 -4, the launch dolly 328 is arranged to move along the track line 100. The driven elongate member 306 extends adjacent to a portion of the track line 100.

In the illustrated embodiment, the launch dolly 328 is passively releasably engageable with the carrier trolley 204. The launch mechanism 300 comprises a braking system 326 acting on the driven elongate member 306 and/or pulley system operatively connected to the launch dolly 328. The braking system 326 acts on the pulley shaft 322, to slow rotation of the third pulley 320 to decelerate the elongate member 306 and launch dolly 328. The braking system 326 is activated when the carrier trolley 204 reaches the release position 304. This slows the launch dolly 328 and causes the carrier trolley 204 to disengage from the launch dolly 328 as the carrier 200 continues to move in the first direction 210 along the track line 100 under its own momentum. The launch dolly 328 may continue to move past the release position 304 after disengaging from the carrier trolley 204 before the braking system 326 brings it to a complete stop. Deceleration of the launch dolly 328 could alternatively be achieved using a different braking system acting on a different part of the launch mechanism 300.

The braking system 326 may be any type of suitable braking system, such as a friction braking system or an eddy current braking system for example.

In alternative embodiments, the launch dolly 328 and/or carrier 200 may comprise a connecting mechanism (such as a releasable latch for example) that connects the launch dolly 328 to the carrier 200. The connecting mechanism may be released when the carrier 200 reaches the release position 304. Any suitable connecting mechanism could be used.

In some embodiments, the driven elongate member 306 is suspended on a cable 330 that extends adjacent to the track line 100. In some embodiments, the driven elongate member is additionally or alternatively supported by a structure 332. In the embodiment shown, the driven elongate member 306 is supported by a structure 332 at a first end 334 via the first pulley 308, and is suspended on a cable 330 at a second end 336 via the second pulley 310. In some embodiments, the elongate member 306 could be supported at both the first end 334 and the second end 336 by a structure. In other embodiments, the elongate member 306 could be suspended on a cable 330 at either the first end 334 or the second end 336 by means other than a structure, such as a rock anchor for example.

Figure 17 shows an alternative configuration in which the first and second pulleys 308, 310 are supported by one or more structures 332, 333. The configuration of Figure 16 may have any of the features described herein, and like reference numerals indicate like parts to Figure 1.

In an embodiment the launch mechanism is arranged to simultaneously launch two or more carriers 200 on the track line 100. In an embodiment, the launch mechanism 300 is arranged to simultaneously launch two or more carriers 200 on two or more respective track lines.

In some embodiments, the launch dolly 328 is arranged to be driven along the track line 100 to the release position 304. Therefore, there is no elongate member 306 required to drive the launch dolly 328. Instead, the launch dolly 328 is driven by a local drive source along the track line 100 in either the first direction 210 and optionally in the second direction 214. Therefore, the launch dolly 328 is a track line driven launch dolly 328A.

Figure 18 shows the track line driven launch dolly 328A. The launch dolly 328A is arranged to push the carrier trolley 204 along the track line 100 in the first direction 210 in the manner described with references to other embodiments. The launch dolly 328A is optionally arranged to drive itself in the second direction 214, such as for capturing the carrier trolley 204 as described elsewhere.

The local drive source may be positioned in the launch dolly 328A itself. The local drive source to drive the launch dolly 328A may comprise an electric motor, an internal combustion motor, a hydraulic motor, a linear induction motor, or any other suitable energy source. In some arrangements, the local drive source is self-contained with its own energy source, such as a battery or fuel tank. In other arrangements, the local drive source is connected to an alternate or additional energy provider or fuel source, such as a power cable connecting between an electric motor on the launch dolly 328A and to an electricity supply elsewhere. The cable may alternatively be a hydraulic hose for use with a hydraulic motor or a pneumatic hose for use with a pneumatic motor.

In use, the local drive source drives the launch dolly 328A along the track line 100. The launch dolly 328A is arranged to engage with the carrier trolley 204 between the engagement position 302 and the release position 304 to accelerate the carrier 200 in the first direction 210 along the track line 100, and to disengage from the carrier trolley 204 at the release position 304 to propel the carrier 200 along the track line 100 in the first direction 210. The local drive source drives the launch dolly 328A from the engagement position 302 and to the release position 304. The local drive source is then stopped or reduced such that the launch dolly 328A releases the carrier trolley 204 at or near the release position 304.

Following the release, in some arrangements, the track 100 driven launch dolly 328A is held at or near the release position 304 after releasing the carrier trolley 204. In other arrangements, the launch dolly moves 328A along the track line 100 towards the higher point 106, or the launch dolly 328A is moved back to the lower point 104. The positioning of the launch dolly 328A may be dependent on further functions as described elsewhere in this document, such as to recapture the carrier trolley 204.

Braking system

The launched zipline amusement ride is configured to decelerate the carrier 200 and safely stop the rider 202 at the end of the ride.

In the illustrated embodiment, in which the rider 202 is propelled by the launch mechanism 300 toward the higher point 106, the rider 202 may return to the lower point 104 in the second direction 214 under the force of gravity. A braking system may be provided to engage with the carrier 200 as the carrier 200 moving in the second direction 214 approaches the release position 304, or between the release position 304 and the engagement position 302 to rapidly decelerate and safely stop the carrier 200. The braking system may be arranged to bring the carrier 200 to a stop at or near the engagement position 302.

The braking system may comprise a known braking system, such as an eddy current braking system. Additionally or alternatively, the launch mechanism 300 may be configured to decelerate the carrier 200 at or near the lower point 104. In some embodiments, the launch mechanism 300 may bring the carrier 200 to a stop as described below. In other embodiments, the launch mechanism 300 may be used in combination with a conventional braking device to bring the carrier 200 to a stop. The conventional braking system may act on the pulleys 308, 310, 320 or the launch dolly 308 or the carrier trolley 204 or a combination of these.

The launch mechanism 300 of figures 1 -4 is configured to act as a braking mechanism. The carrier trolley 204 is configured to act on the launch dolly 328 in a second direction 214 that is opposite to the first direction 210 such that inertia of the driven elongate member 306 and pulley system operatively connected to the launch dolly 328 decelerates the carrier 200. The braking system 326 for the launch mechanism 300 may also be activated to provide a braking force on rotation of the pulleys 308, 310, 320, to brake the carrier 200 in a controlled manner. In alternative embodiments, the braking system may be distal from the launch mechanism 300. For example, in the alternative embodiment where the track line 100 is inclined in a generally downwards direction from a higher point proximal to the release position 304 to a lower point distal from the release position 304, the braking system may be provided at or near the lower point. The braking system could comprise a second launch mechanism 300 (not illustrated) proximal to the lower point and arranged to brake the carrier 200 as described above. The second launch mechanism 300 may also be arranged to return the carrier 200 to the higher point. Similar arrangements could be utilised in embodiments where the track line 100 extends between two points that are at about the same height.

The track driven launch dolly 328A as described above with reference to Figure 18 may be utilized as a braking system as hereinbefore described. For instance, following the release, the track 100 driven launch dolly 328A is held at or near the release position 304 after releasing the carrier trolley 204 and re-captures the carrier trolley 204 when travelling in the second direction 214 to decelerate the carrier 200 in a controlled manner.

Catching mechanism

Figures 5 and 6 show a catching mechanism 400 arranged to releasably couple to the carrier 200 as the carrier 200 approaches the higher point 106. The catching mechanism 400 comprises a capture trolley 402 +s arranged to pull the carrier 200 towards the higher point 106 when the carrier 200 is unable to reach the desired height under its own momentum.

Figure 5 shows the carrier 200 approaching the higher point 106 in the first direction 210 towards the end of launch momentum. A capture trolley 402 is arranged to move along the track line 100 to interface with the carrier trolley 204.

In the embodiment shown, the capture trolley 402 comprises an electromagnetic latch member 404 that interacts with a corresponding electromagnetic latch member 406 on the carrier trolley 204. Alternatively, a different type of capture mechanism could be used, such as a remotely or automatically actuated mechanical latch.

The capture trolley 402 is operatively connected to a winching mechanism 408, for example via a suitable cable, conveyor, or belt 410.

Once the respective electromagnetic latch members 404, 406 are engaged, the carrier 200 may be winched towards the higher point 106 using the winching mechanism, as shown in figure 6.

In some embodiments, the initial position of the capture trolley electromagnetic latch member 404 may be adjusted prior to commencement of the ride to account for rider weight and/or weather conditions.

In an embodiment, the carrier 200 is released at or near the higher point 106 by releasing the electromagnetic latch to return to the lower point 104 under gravity.

The catching mechanism 400 provides several advantages. In some embodiments, it may be desirable to catch the carrier 200 as it approaches the higher point 106. For example to increase the suspense of the ride by holding the rider at or near the higher point 106 before releasing the rider back to the lower point 104 under the force of gravity. In addition, riders of different weights may be propelled different distances by the launch mechanism 300, and the distance a rider travels may also be affected by weather conditions (a head wind, for example, may result in the rider travelling a shorter distance). Therefore, being able to pull the carrier 200 to the higher point 106 helps ensure that all riders can enjoy a similar ride experience. The catching mechanism 400 also allows for embodiments where a rider 202 can disembark the ride at the higher point 106.

Boost mechanism

Figures 7-10 show a boost mechanism 500 for accelerating the carrier 200 part-way through a ride, for example to prolong the duration of the ride and/or to add excitement to the ride experience. The ride may initially be launched by a configuration such as that described above, or by a different configuration.

The boost mechanism 500 has generally similar features to the launch mechanism 300. Unless described below, the features, functionality, and alternatives are the same as for the launch mechanism 300 of figures 1 -4, and like reference numerals are used to indicate like parts, with the addition of 200.

The boost mechanism 500 is arranged to engage with the carrier 200 between a boost engagement position 502 and a boost release position 504 to accelerate the carrier 200 in the first direction 210 along the track line 100, and to disengage from the carrier 200 at the release position 504 to propel the carrier 200 along the track line 100 in the first direction 210. The boost engagement position 502 is spaced apart from the release position 504 of the boost mechanism 500. The boost mechanism 500 is arranged to engage with the carrier 200 when the carrier 200 is moving in the first direction 210.

The boost mechanism 500 may accelerate the carrier 200 in any suitable direction, including uphill, downhill or substantially horizontally.

Instead of a launch dolly, the boost mechanism 500 has an engagement member 540 operatively connected to the driven elongate member 506. The engagement member 540 is arranged to engage with a complementary member 216 located at the top of the trolley 204. In the illustrated embodiment, the engagement member 540 is a hook and the complementary member 216 is a bar. In other embodiments, any suitable engagement and complementary members may be used.

The engagement member 540 is positioned above the track line 100 to allow the carrier 200 to pass underneath the engagement member 540 prior to engagement of the engagement member 540 with the complementary member 216. The engagement member 540 comprises a sensor (not illustrated) for detecting that the carrier 200 has passed underneath it. The sensor could be any suitable mechanical, electrical or electromechanical device. The sensor may comprise part of the motor control system.

The first and second pulleys 508, 510 are height adjustable to enable the engagement member 540 to be positioned at the correct distance above the track line 100. It may be necessary to change the height of the pulleys 508, 510 to account for differences in the height of the track line 100 due to temperature changes (a metal track line will expand in hotter temperatures, and may cause the track line to sag more than in colder temperatures, for example).

Referring to figure 8, the boost mechanism 500 also comprises a known tensioner. The tensioner 542 is movable to increase and decrease tension on the driven elongate member 506. The tension in the elongate member 506 may be reduced to allow the carrier 200 to pass underneath the engagement member 540.

Any suitable mounting and height adjustment mechanisms may be used for the first and second pulleys 508, 510, and the tensioner 542. The process of adjusting the height of the pulleys 508, 510, and the tensioner 542 may be automated, for example by the use of a known hydraulic actuator system

Referring to figure 9, once the carrier 200 has passed under the engagement member 540 and triggered the sensor, tension on the elongate member 506 is increased. The energy source 512 then provides energy to the elongate member 506 to accelerate the carrier 200 in a similar manner as described above with respect to energy source 312. The engagement member 540 engages with the complementary member 216 to accelerate the carrier 200 in the first direction 210.

Figure 10 shows the boost mechanism 500 releasing the carrier 200 at the release position, in a similar manner to the launch mechanism 300 of figures 1 -4.

Some alternative arrangements for the launch mechanism will now be described.

Alternative launch mechanism for alternative braking

Figures 11 -14 show an alternative embodiment of a launch mechanism 600 in which the launch dolly 628 is arranged to be raised and lowered relative to the driven elongate member 606 such that the carrier trolley 204 and thereby the carrier 200 can pass underneath the launch dolly 628. Unless described below, the features, functionality, and alternatives are the same as for the launch mechanism 300 of figures 1 -4, and like reference numerals are used to indicate like parts, with the addition of 300.

The launch mechanism 600 comprises a tensioning member 642. The tensioning member 642 is moveable to increase and decrease tension on the driven elongate member 606. The tension in the elongate member 606 is increased to lift the launch dolly 628 away from the elongate member 606 such that the carrier trolley 204 of the carrier 200 can pass underneath the launch dolly 628. The tension in the elongate member 606 is decreased to lower the launch dolly 628 towards the track line 100 so that the launch dolly 628 can engage with the carrier trolley 204.

In the embodiment shown, the driven elongate member 606 is suspended on a cable 630 via the first and second pulleys 608, 610. In alternative embodiments, one or both of the first and second pulleys 608, 610 may be supported by a structure. In an embodiment, the height of the first and second pulleys 608, 610 may be adjustable to raise and lower the height of the dolly 628, in addition to or instead of the tensioning member 642.

In this embodiment, the track line 100 includes a braking section 108 that extends from the engagement position 602 in a generally upwards incline in a direction away from the higher point 106. The upwards incline of the braking section 108 acts as a brake on the carrier 200. The carrier 200 may also be braked by a conventional braking system (not shown) located on or near the braking section 108 of the track line 100.

Figure 1 1 shows the carrier 200 returning in the second direction 214. The launch dolly 628 is lifted away from the elongate member 606 to allow the carrier trolley 204 to pass underneath the launch dolly 628. As shown in figure 12, after passing under the launch dolly 628, the carrier 200 continues to travel in the second direction 214 up the braking section 108 of the track line 100. The increasing height of the braking sectionl 08 and/or the conventional braking system causes the carrier 200 to slow to a stop and change direction.

The carrier 200 then travels back in the first direction 210 and the carrier trolley 204 engages with the launch dolly 628 from the opposite direction. Alternatively, the carrier 200 may be braked by conventional means at or near the engagement position 602 without the need to engage with the launch dolly. After the carrier 200 stops moving, the launch dolly 628 is lowered into engagement with the carrier trolley 204 to bring the carrier 200 and launch mechanism 300 into an initial position. As shown in figures 12 and 13, the carrier 200 may be launched from the initial position by accelerating the launch dolly 628 along the track line in a similar manner as described above in relation to figures 1 -4.

The launch mechanism 600 described above advantageously reduces the impact on the launch dolly 628 during braking compared with the dolly-based braking system described above in relation to figures 1 -4. The additional travel experienced by the rider along the braking portion 108 may also add a further dimension to the ride experience.

In the configuration shown, the launch dolly 628 and the carrier trolley 204 have complementary engaging surfaces that are shaped to inhibit uplift on the launch dolly 628 by locking that into the carrier trolley 204.

Alternative launch mechanism below carrier

Figure 15 shows an alternative embodiment of a launch mechanism 700 in which the driven elongate member 706 is located below the carrier 200. Unless described below, the features, functionality, and alternatives are the same as for the launch mechanism 300 of figures 1 -4, and like reference numerals are used to indicate like parts, with the addition of 400.

Instead of a launch dolly, the launch mechanism 700 has an engagement member 740 operatively connected to the driven elongate member 706. The engagement member 740 is arranged to engage with a complementary member 218 located at the bottom of the carrier 200. In the illustrated embodiment, the engagement member 740 is a hook and the complementary member 218 is a bar. In other embodiments, any suitable engagement and complementary members may be used.

The first and second pulleys 708, 710 are height adjustable to enable the engagement member 740 to be positioned at the correct distance below the track line. It may be necessary to change the height of the pulleys 708, 710 to account for differences in the height of the track line 100 due to different rider weights or temperature changes that may cause the track line to sag to a greater or lesser extent. The launch mechanism 700 also comprises a tensioner 742. The tensioner 742 is movable to increase and decrease tension on the driven elongate member 706.

Any suitable mounting and height adjustment mechanisms may be used for the first and second pulleys 708, 710, and the tensioner 742. The process of adjusting the height of the pulleys 708, 710, and the tensioner 742 may be automated.

The launch mechanism 700 may be arranged to brake the carrier 200 on its return in a similar manner as described above in relation to figures 1 -4. The launch mechanism 700 may also be arranged to allow the carrier 200 to pass over the engagement member 740 on its return (by lowering the pulleys 708, 710) to brake the carrier 200 in a similar manner as described above in relation to figures 1 1 -14.

Low impact braking system

Figures 19-21 show an embodiment of a braking mechanism 300 for a zipline amusement ride comprising a low impact braking system. In the embodiment, there is a track line 100 comprising a tensioned, suspended cable 102. There is a carrier 200 for carrying a rider 202, the carrier 200 has a carrier trolley 204 adapted to move along the track line 100 in a first direction 210 and a second direction 214. A braking mechanism 300 is provided that has a braking dolly 328 arranged to engage with the carrier 200 in a braking region along the track line 100 to decelerate the carrier in a second direction 214. Both the carrier 200 and the braking dolly 328 are arranged to be moving in the second direction 214 when the carrier 200 engages with the braking dolly 328 in order to reduce the force of the impact. The features, functionality and alternatives for the braking system may utilize the same or similar features, functionality and alternatives as those for the launch mechanism 300 of figures 1 -4. Therefore, like reference numerals are used to parts which can be utilized for both. However, for the avoidance of doubt, the braking mechanism 300 may be utilised solely for the purpose of low impact or smooth braking. For example, the braking mechanism 300 may be used in a zipline amusement ride that has a different launch mechanism, or that does not have a launch mechanism and instead operates solely under the force of gravity.

In the illustrated embodiment, a rider 202 travels along a track line 100 in a first direction 210 or a second direction 214. The rider is propelled along the track line by a force such as gravity or additionally / alternatively by an additional force such as those described above. To stop the momentum of the rider, a braking system may be provided to engage with the carrier 200 in the braking region 802 as the carrier 200 is moving in the second direction 214 to rapidly decelerate and safely stop the carrier 200.

The braking mechanism 300 utilises a braking dolly 328 to act as a braking system. The carrier trolley 204 is configured to act on the braking dolly 328 in the second direction 214 such that the braking dolly 328 decelerates the carrier 200 through the inertia of the pulley system with additional braking means arranged to act on the pulley system as required. However, to reduce the rate of change in kinetic energy from sudden equalisation of the braking dolly 328 and carrier 200 speeds, the braking dolly 328 is operated to move in the second direction 214 prior to engagement with the carrier trolley 204 of the carrier 200 in the braking region 802. Therefore, the speed differential between the braking dolly 328 and the carrier trolley 204 is reduced compared to a braking dolly 328 or stop that is stationary at the point of engagement with the carrier trolley 204. In an embodiment, following engagement, the braking dolly 328 and thereby the carrier trolley 204 is decelerated with reference to the second direction 214 such that the carrier 200 comes to a stop at a desired stopping point which may be at or near a lower position 104 of the track line 100.

The braking dolly 328 may decelerate at the moment of engagement with the carrier trolley 204, may decelerate prior to engagement with the carrier trolley 204, or may decelerate after engagement with the carrier trolley 204.

Figures 19-21 illustrate the process of recapture of the carrier trolley 204 by the braking dolly 328 moving in the second direction 214. As shown in Figure 19, the braking dolly 328 is positioned on the track line 100 in the braking region 802 and the carrier trolley 204 and carrier 200 moves in the second direction 214 toward the braking dolly 328. In this embodiment, upon the carrier trolley 204 moving in the second direction 214 nearing the braking dolly 328, the braking dolly 328 is also moved in the second direction 214.

Figure 20 shows the continued movement of the braking dolly 328 in the second direction 214 prior to engagement with the carrier trolley 204. The braking dolly 328 moves from the initial position on the track line 100 in the braking region 802 in the second direction 214. The carrier trolley 204 also moves in the second direction along the track line 100. However, the movement of the carrier trolley 204 is greater than that of the braking dolly 328, therefore, the distance between the braking dolly 328 and carrier trolley 204 reduces whilst both the braking dolly 328 and carrier trolley 204 move in the same second direction 214.

Figure 21 shows the engagement between the braking dolly 328 and the carrier trolley 204 which have both been moving in the second direction 214. Upon engagement, the movement speed between the carrier trolley 204 and the braking dolly 328 equalises. Therefore, generally, the carrier trolley 204 will decelerate to the speed of the braking dolly 328. However, in some cases the braking dolly 328 may be accelerated to the speed of the carrier trolley 204, or both changes in speed occur. However, the change in speed at the point of engagement for a moving braking dolly 328 is less than the change of speed with a stationary braking dolly 328 or stop. Following engagement, the braking dolly 328 and engaged carrier trolley 204 are decelerated.

The deceleration may be controlled by the braking dolly 328 in the manner described above with reference to the braking system for a launch dolly 328. For instance, the launch mechanism 300 of figures 1 -4 may be configured to act as a braking mechanism. The braking system 326 for the launch mechanism 300 may also be activated to provide a braking force on rotation of the pulleys 308, 310, 320, to brake the carrier 200 in a controlled manner.

The braking dolly 328 is driven in the second direction 214 by the braking mechanism 300. The braking mechanism 300 may operate in the reverse direction to that of the launch mechanism described with reference to Figures 1 -4 such that the elongate member 306 travels through the pulleys 308, 310 in the opposite direction to the launch process. Alternatively, in some arrangements, the track driven braking dolly 328, which shares similar features with the track driven launch dolly 328A as described above with reference to Figure 18 may be utilized to be driven along the track line 100 in the second direction 214.

The control of the movement of the braking dolly 328 in the second direction 214 prior to engagement with the carrier trolley 204, may be coordinated by manual or automated systems. Automated systems may include mechanical and/or electric switches that are actuated and provide a mechanical and/or electrical output in response to actuation. The output(s) may be used to control further functions. Alternatively, a controller comprising a computer with a processor, memory and storage may be utilized to produce an output in response to an input, such as from a sensor in accordance with set parameters. In some embodiments, the control can be based on time of release of carrier 200 for an expected travel time.

In one embodiment, an operator (or rider) may operate the braking dolly 328 to move in the second direction 214 upon the nearing of the carrier trolley 204 moving in the second direction 214. Braking of the braking dolly 328 to decelerate the carrier 200 following engagement may also be controlled manually upon the operator (or rider) operating the braking dolly 328. In an alternative embodiment a control system controls the braking dolly 328 to begin movement when the carrier trolley 204 is travelling in the second direction 214. In one embodiment, the control system comprises at least one sensor 800 to trigger the movement of launch dolly 328 in the second direction 214. A number of sensor locations or sensor types may be utilised for this. In an illustrated embodiment in Figure 22, the sensor 800 is positioned at a detection point between outside of a braking region 802 in the first direction 210 along the track line 100. The sensor 800 detects the passing of the carrier trolley 204 in the second direction 214 and controls the braking dolly 328 (such as via the braking mechanism 300) to move in the second direction 214. The carrier trolley 204 engages with the moving braking dolly 328 at a location within the braking region 802. The braking dolly 328 decelerates the carrier trolley 204 to bring the carrier 200 to a stop.

Multiple sensors 800 positioned at detection point(s) may be provided to control the movement of the launch dolly 328. For instance, in some embodiments, a first sensor 800 controls the movement of the braking dolly 328 upon detection of the carrier trolley 204 and a second sensor 800 is used to confirm whether the braking dolly 328 needs to change speed given the speed of the carrier trolley 204 based upon the detection time between the two sensors. A weight of the carrier 200 could affect the speed of the carrier trolley 204 along the track line 100. The sensors 800 generally detect or determine a parameter of the carrier 200. The sensors can be proximity sensors, movement sensors, photoelectric sensors (that may count reflectors in the track, for instance) or any other suitable sensor.

Alternatively, or additionally, the sensor monitors the condition of the carrier trolley 204 or carrier 200 itself. For instance, the sensor may be used to measure the speed of the carrier trolley 204 along the track line 100 to determine the moment to operate the launch dolly 328 and the speed of the launch dolly 328. In such a case, the parameter may be detected / determined by an altitude sensor (to determine a height and thus position), speed sensor, weight sensor, ultrasonic sensor, barometer, accelerometer, ultrasonic sensor, pressure sensor or location sensor (e.g., GPS), or any other suitable sensor. Sensors or parameters can be combined, such as a weight sensor combined with a timer for an expected speed calculated based on the weight and known track length. A further detector or sensor may be utilised to detect engagement between the braking dolly 328 and the carrier trolley 204 to control the deceleration of the braking dolly 328.

Additionally, or alternatively, the braking dolly 328 may be operated to always begin deceleration at a point along the track line 100 within the braking region 802 to ensure that sufficient time is provided to successfully brake the launch dolly 328.

To ensure the carrier trolley 204 catches the second direction moving braking dolly 328 to engage, the speed of the carrier trolley 204 along the track line is greater than that of the braking dolly 328 within the braking region 802 during the braking process.

Whilst the braking dolly 328 has been described as operating solely as a braking dolly 328 for the braking system 300, in some embodiments, the braking dolly 328 may be utilised as the launch dolly 328 in the launch mechanism 300. For instance, in an alternative embodiment of a launch mechanism 300 with reference to Figures 19-22, the rider 202 is propelled by the launch mechanism 300 toward the higher point 106, the rider 202 may return to the lower point 104 in the second direction 214 under the force of gravity. Where the launch mechanism 300 is configured to also act as a braking system, the carrier trolley 204 is configured to act on the launch dolly 328 in the second direction 214 such that the launch dolly 328 decelerates the carrier 200 in the manner described with reference to the braking dolly 328 above. Therefore, to reduce the rate of change in kinetic energy from equalisation of the launch dolly 328 and carrier 200 speeds, the launch dolly 328 is operated to move in the second direction 214 prior to re-engagement with the carrier trolley 204 of the carrier 200 in the braking region 802. Therefore, the speed differential between the launch dolly 328 and the carrier trolley 204 is reduced compared to a launch dolly 328 that is stationary at the point of re-engagement with the carrier trolley 204.

In this embodiment, the distal point of the braking region 802 may be the release position 304, and the braking region 802 extends between the release position 304 and the engagement position 302 to rapidly decelerate and safely stop the carrier 200 at or near the engagement position 302 or at a stopping point near the lower point. In alternative embodiments, the braking system 300 may be distal from the launch mechanism 300. For example, in the alternative embodiment where the track line 100 is inclined in a generally downwards direction from a higher point proximal to the release position 304 to a lower point distal from the release position 304, the braking system may be provided at or near the lower point. The braking system could comprise a second launch mechanism 300 (not illustrated) proximal to the lower point and arranged to be moving in the same direction as the carrier 200 prior to engagement with the carrier trolley 204 to brake the carrier 200 as described above. Additionally, or alternatively, the launch mechanism 300 may be configured to decelerate the carrier 200 at or near the lower point 104 and be moving in the same direction as the carrier 200 prior to engagement with the carrier trolley 204 to brake the carrier 200.

The braking system may comprise a known braking system, such as an eddy current braking system.

Preferred embodiments of the invention have been described by way of example only and modifications may be made thereto without departing from the scope of the invention.
