Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] The present invention relates to leisure and amusement slide
tracks and particularly to water slides and this application claims
priority under 35 U.S.C. .sctn.119 to Netherlands patent
application NL1039884, filed Nov. 8, 2012, the disclosure of which
is incorporated herein by reference.
BACKGROUND OF THE INVENTION
[0002] The use of slide tracks is known in the prior art. More
specifically, slide tracks heretofore devised and utilized for the
purpose of entertaining users by permitting slidable movement down
the slide way are known to consist basically of familiar, expected
and obvious structural configurations. Slide tracks in general are
fabricated from rigid material configured into twists and turns to
provide variety and entertainment for the user. A rider travels
down the slide track and, because of the rigidity of the slide,
travels in a predetermined slide track which is repeated on
subsequent uses. The slide track usually starts with an entry to
the slide track, a main slide way segment and an exit segment, the
latter often comprising means to slow the rider down and to let the
rider disengage from the slide track.
[0003] Constructions have been attempted to improve the sliding
experience. For this purpose e.g. water slide tracks (hereinafter
waterslides) are currently known, which are provided with a water
supply. Typical waterslides are made of polyester, fiberglass,
Resin Transfer Molding Composites or other materials troughs and/or
tubes that are aligned and coupled together to provide a fixed and
generally downward sloping flow path. Waterslides (e.g., body
slides, inner tube slides, raft slides) may be designed for an
individual (hereinafter a rider) to ride without a transport device
or with a transport device (e.g., on an inner tube, boat or raft
(hereinafter also referred to as rider unless specifically
otherwise stated). In operation, water is typically pumped to the
top of the traditional waterslides and into associated troughs
and/or tubes such that the water passes along the flow path. Riders
may then enter through the entry at the top of the slide and be
propelled along with the water from the top of the slide to the
bottom of the slide. Gravity and/or pumps generally create the
motive force to bring the water (and any rider(s) riding the slide)
to the bottom of the slide. Additional water may be injected along
the path to alter the rider velocity. The water provides
lubrication and a sliding enhancement medium. In some cases, water
may be replaced by polishing the sliding surface of the slide so as
to make a slippery surface on which to slide. Other sliding aids
may also be used. Examples include a waxed bag, a mat or a special
suit.
[0004] Waterslides are often equipped with a water volume at the
exit segment to slow the rider down towards the exit of the slide
or a swimming pool in which the rider plunges right after the exit
of the slide track.
[0005] Current slide track have several disadvantages, one of which
comprise that the capacity--defined as number of riders per time
unit--is limited by the time it takes for one rider to complete the
slide track and to exit the slide track. The slide track is usually
only cleared for a new rider to enter, if it is estimated that the
previous rider is safe, meaning that at least the chance should be
acceptably low that a next rider bumps into the previous rider. For
this purpose currently means are provided to detect if a rider has
left the slide track. Often, whether or not the slide track is
cleared for the next rider to enter is indicated by a light signal
near the entry of the slide track, wherein a red light communicates
that the slide track may not be entered and a green light
communicates that the next rider may enter the slide track. In
other cases a gate may be provided to physically prevent a next
rider entering the slide track if the slide track is not cleared.
These safety procedures usually result in long waiting times and
waiting queues for customers. In order to satisfy the customers and
limit the waiting times, amusement parks (for example water parks)
often put more of the same slides or symmetric slides in their park
to allow more riders to experience a ride at the same time.
[0006] Another solution to increase the overall capacity of the
slide track is to make family slides or raft slides, so more people
may go the same time into the slide in a raft.
[0007] U.S. Pat. No. 3,830,161 by Arrow Development Co. for example
discloses a flume amusement ride wherein passengers ride in boats
that float on water flowing in water channels, the boats being
guided by the walls of the water channel. A steep down chute
portion is provided as part of the ride as a means of providing a
thrill to the passengers. The down chute portion includes two
adjacent water channels into which boats are alternately directed
by a gate that is constructed of two parallel wall members hinged
to the walls of the single water channel upstream of the down
chute. It claims an increase of the capacity and is directed
towards the use of boats and rafts.
[0008] Netherlands patent NL9301619A discloses a water slide
provided with an entry end which lies at a starting level, an exit
end which lies at a lower level and a slide path lying between
these ends; during use, water is added to the slide path. The slide
is provided with means for at least locally substantially varying
the flow of water on the slide path over the course of time during
use. The slide is preferably provided with at least one
water-collection basin, and water which is collected in the
collection basin may be moved from the basin to the following part
of the slide path substantially all at once. In one embodiment a
selection segment is proposed which enables a rider to be
transported to one of a plurality of follow up slide ways. The
rider arriving from an upstream slide way at the selection segment
plunges in the selection segment which comprises a water-collection
basin. The selection segment is movable around one of two
diagonally crossing swivel axes' to connect to one of the
underlying slide ways. The rider is subsequently further
transported together with the load of water from the selection
segment comprising a water collection basin to the underlying slide
way. The water which is collected in the selection segment is
therefore moved from that basin to the following part of the slide
path substantially all at once.
BRIEF SUMMARY OF THE INVENTION
[0009] It is an object of the invention to provide a solution for
improving the throughput of the slide track, in order to increase
capacity of the slide track. The invention realizes the objectives
in the following manner.
[0010] In the slide track a selection segment is constructed which
provides a continuous flow path for a rider on the slide track
entering the selection segment from an upstream slide way, to one
of a plurality of downstream slide ways. In a preferred embodiment
the selection segment rotates alternatively from a first position
to a second position in order to divert a rider to an empty
downstream slide way.
[0011] It is readily understood that the terms downstream and
upstream merely indicate a relative location. Downstream means in
this case following the direction to which the rider heads from a
point of view of the selection segment, whereas upstream means the
direction from which a rider arrives from the point of view of the
selection segment.
[0012] By selectively transporting the rider to an empty downstream
slideway the capacity is increased in positive relation with the
amount of available downstream slide ways.
[0013] The downstream slideway may comprise an exit slide way,
comprising a run-out, slow-down or water basin at the end of the
slide track. It is especially advantageous to provide selectable
exit slide ways, because just a single main slideway needs to be
constructed and multiple (less expensive) exit slide ways, while
achieving the benefits of the invention. It is known that most time
is lost at the exit slide way, because riders need to be slowed
down, recuperate, and leave the slide track in a safe manner.
[0014] In the proposed invented configuration with e.g. two exit
slide ways instead of one, the time between a first rider being
allowed to enter the slide track and a second rider being allowed
to enter the slide track may decrease up to a factor two, which
results in an increase of capacity by up to 200% of its normal
capacity. With three exit slide ways the capacity increase up to
approximately 300% and so forth.
[0015] Furthermore the selection segment is arranged in such a way
that the rider is at the most just marginally slowed down in the
selection segment itself, or even sped up if a slope is provided in
the selection segment. The flow path is therefore not interrupted
in time or space. In this way the speed of transport to the
downstream slide ways may be substantially maintained, which
prevents delay in the selection segment, thus preventing possibly
dangerous situations if, in an unwanted situation, a next rider
enters the slide track too soon. The chance that a collision of
riders occurs in the selection segment is therefore greatly
reduced.
[0016] Ultimately this leads to an optimized throughput and higher
capacity of the slide track, less negative influence on speed of
the descending rider, a safer use of the slide track and in general
more fun for the rider.

DETAILED DESCRIPTION OF THE INVENTION
[0026] The invention is now described by the following aspects and
embodiments, with reference to the figures. There are different
configurations with different shapes of selection segments. In the
figures below a detailed description is given of these
configurations.
[0027] To increase the capacity of the slide, a plurality of exit
sections is provided to decrease the time it takes to exit the
slide track. When the first rider has passed the selection segment,
the selection segment moves to a second position so the next rider
follows a flow path and ends up in the second downstream slide way.
If there are more than two exit sections, the selection segment
goes to its next position, the next rider passes, and the selection
segment moves to the next position, and so onwards. When the last
position is reached, and the user has passed the selection segment,
the selection segment goes back into its first position. With two
exit segments the capacity is approximately 200%, with three exit
segments the capacity is approximately 300%, and so forth.
[0028] In a setup of a so called fast body slide, with one exit,
where the ride takes 7.5 seconds from the entrance till the rider
is in the exit segment and 10 seconds to exit, normally the traffic
lights use a timer of 20 seconds between two riders. This results
in a capacity of 180 people per hour. When there are two separate
exit sections, the next rider may already go when one exit section
is full and the other one is clear. This means that every 10
seconds a next rider may go and the 2.5 seconds may be used to move
the selection segment into the next position. This means a capacity
of 200% of 360 people per hour and the waiting times will be cut in
half. The operation of the slide track is still in accordance with
every safety standard.
[0029] In a setup of a so called short fast speed slide, with one
exit, where the rider takes 5 seconds to complete the slide until
the exit and takes 10 seconds to exit, normally the traffic lights
use a timer of 20 seconds between two riders. In the same slide,
configured with a selection segment and three exit sections, and a
time of 1 second to switch position from the selection segment,
every 6 seconds a rider may go and the rider has 12 seconds to
exit. This results in a capacity of 333%.
[0030] FIG. 1 shows a slide track 100 a first position, which may
be a default position. This figure comprises three different
segments, an upstream segment 101, a selection segment 300a, and a
downstream slide way segment 103. A slide track usually starts with
an entry to the slide track, which often comprises multiple slide
way sections. A middle slide way section may comprise twists and
turns to provide variety and entertainment for the user. This path
may be long, short, steep, smooth, enclosed or opened on top. The
structure may be outdoor or indoor or any combination thereof. A
small piece of this possible middle slide way section is showed in
FIG. 1 as upstream segment 101. This part may be the end of a
straight part, the end of a corner or may be a special object for
the fun of the rider. The upstream segment may have a small
diameter for speed slides, a bigger diameter for raft slides, or a
really big diameter for family raft slides. The selection segment
300a is movably connected 104 to the upstream section 101. This may
be done with a joint or with only coincident sections. This joint
may comprise a seal to make the transition of the user from section
101 to section 300a a smooth transition and prevents leakage of
water. This joint may be a supporting point for the slide track.
There may be a construction to support the structure from its
foundation. The selection segment 300a may be set in multiple
positions to select one of a plurality of downstream slide paths
105a,b.
[0031] For safety reasons a default position 105a is provided. If
the actuator system or safety system fails for example by a power
cut the selection segment moves automatically to its default
position. A safety mechanism may use a counterweight or a spring
load to rotate the system back into the default position.
[0032] FIG. 1 shows a downstream slide way segment 103 to slow the
rider down, to recuperate the rider and to exit the slide. This
segment may comprise a body of water to slow the rider down. This
example segment comprises two different downstream slide ways, with
default first slide way 105a and second slide way 105b. The
downstream slide way segment may, however, consist of more than two
downstream slide ways. The slide ways are shown as parallel slide
ways by means of example, but may be designed with curves, or in a
V-shape. The rider may continue his ride for a longer time in a
separated slide ways or may end immediately in an exit downstream
slide way segment 103.
[0033] The downstream slide way segment 103 (preferably smoothly)
separates the beginning shape into two or more slide paths. Wall
108 creates gradually a separation wall between the downstream
slide ways. This wall guides the rider safely into a slide way free
of occupants. The connection between the selection segment 300a and
downstream slide way segment 103 may include a seal to prevent
water leaking and providing the rider a smooth transition. The
shape of the beginning of the downstream slide way segment is
designed in a way it gives the rider a smooth transition.
[0034] The side walls of the downstream slide way segment 109a and
109b make sure a rider is guided safely into the slide way. The
length of the downstream slide way segment will be at least
dimensioned dependent on the speed the fastest possible rider has
when entering the downstream slide way segment.
[0035] The downstream slide way segment 103 and selection segment
300a may be fixed connected to each other. This means the exit
segment rotates or moves too.
[0036] The downstream slide way segment 103 may be replaced by a
plunge pool 602, comprising a swimming pool to slow down the rider.
The selection segment may be just above the plunge pool or may be
placed on a height of several meters to create a drop-off for the
rider to fall into the plunge pool.
[0037] Sensors may be provided for the actuator and safety system,
and may be placed in the upstream segment 101 to detect arriving
riders and to detect how much time lapses between subsequent
riders. Sensors may be provided to detect the position of the
selection segment. These may be connected to the selection segment.
In the downstream slide way segment there may be sensors to detect
a rider in each slide path. A combination of these sensors and a
processor or computer may control the actuator to rotate the
selection segment.
[0038] A safety system may be provided for detecting when riders
are too close to each other and the system may prevent moving the
selection segment if riders are too close to each other. This makes
sure that there are no riders near the exit of the selection
segment while moving the selection segment.
[0039] The actuator system may work with a mechanical system. The
weight of the rider or the shifted water level may actuate the
selection segment to rotate. This may work with levers, water
pressure, or other means.
[0040] The different slide way sections may be connected to each
other with a tube or connected section to stabilize the water level
and to ensure this is the right height to slow the rider down.
[0041] FIG. 2 shows a Slide track 100 of FIG. 1 but in the second
position.
[0042] FIG. 3 shows a selection segment 300a. The cross-section at
rear 302 preferably fits to the upstream slide way segment 101. It
may for example be shaped like a circle or a part of a circle to
obtain a smooth transition from the upstream segment to the
selection segment. The top of the circle could be cut off to obtain
an open or half open slide.
[0043] The front cross-section 303 of the selection segment may
have different shapes. It may be in the shape of a wide slot and a
part at the top may be cut off. Or it may be in the shape of an
ellipse or it may be a combined shape of a slot, an ellipse, circle
or straight lines.
[0044] The selection segment may obtain a safety shield 304 under
the front cross-section to prevent safety issues that riders may
get stuck under the selection segment and get injured. Between the
safety shield and the downstream slide way segment there may be a
seal provided to smoothen the ride and to prevent leakage of
water.
[0045] The shape of the slide path may be designed by adjusting the
shape of the selection segment. It may be in a V-shape but the ride
may be smoothened by designing a smooth curve. This may be a single
radius or may be a double curve 305.
[0046] The rotation axis is longitudinal rotatable defined
substantially perpendicular to the cross-section at the rear 302.
If it is designed differently a special joint is needed in the ends
302 and 303 of the selection segment 300a. The shape of the front
cross section 303 may be transferred parallel to the rear cross
section 302 so that the bottom line of this shape may be coincident
with the rotation axis. This place of the rotating axis is
important for solving or creating design problems. The rotation
axis may be horizontal or on an angle when viewed from the side.
This means that the whole selection segment 300a may tilt a bit
compared to the downstream slide way segment.
[0047] The selection segment may be made of one piece of fiberglass
or other material or may be made out of different pieces and
mounted together.
[0048] The shape of the front cross section 306 may have an
elevated piece in the middle to initiate the dividing of the two
slide ways with using a wall like 108. This may be at the end of
300a.
[0049] Flexible floors may be used to force riders into the
different downstream slide ways. The selected slide way is then
lowered and/or the non-selected slide way(s) are moved in a higher
position so gravity forces the rider follow the flow path into the
selected downstream slide way. The selection segment may be fixed
connected to the upstream segment and the downstream segments, and
the selection segment may be made of a flexible material. The
flexible material may comprise rubber, elastomer such as Ethylene
Propylene Diene Monomer (EPDM) rubber, or flexible, resilient or
deformable plastic, or combinations thereof, for example by
layering different materials. By adjusting the shape of the
flexible selection segment the rider follows a flow path through
one of the selected downstream slideways. Shaping of the flexible
material may comprise creating a bump in the flow path or a local
lowering of the floor a ridge to force the rider to follow the
lowest path, or the path with least resistance or obstacles.
[0050] FIG. 4 shows a rear view of the system, and comprises
section A as indicated in FIGS. 1 and 2. The base 401 is connected
to the floor and/or foundation, to support the segment section 300a
when it is in the first or second position. The base creates an
even transition between the selection segment 300a and the
downstream slide way section 103.
[0051] The selection segment may be rotatable supported at
different places. The whole circular shaped safety shield 306 may
be part of a ball-bearing or may slide over a part of the base
provided with lubricant. The selection segment 300a may comprise
other circles or parts of circles that function as a bearing or
joint to support the selection segment 300a.
[0052] The rotating mechanism may be connected at different places.
It may use a big sprocket wheel, with an electrical motor having a
small sprocket wheel to drive the selection segment. The selection
segment may be driven by a hydraulic system or pneumatic system. A
belt system may be used or a rack and pinion system or a linear
actuator. The rotating mechanism may be mechanically activated.
[0053] FIG. 5 shows a variation of a selection segment 300b. The
front cross section 303 may triangular and may have filleted edges.
Other variations comprise square or polygon shapes having filleted
edges and a radius of each corner to fit the radius of
corresponding downstream slide way. By using this shape, the
rotation may be in just one direction, either clockwise or counter
clockwise. This may result in two or more slide paths in the
downstream slide way segment.
[0054] This shape may be used to fit a theme of the slide track and
make the product more appealing and fun to use.
[0055] FIG. 6 shows a slide track in a configuration with a
rotating curved selection segment 300c. The selection segment 300c
may comprise multiple curves and/or straight sections. In this
figure the downstream slide way segment 602 is a plunge pool, deep
enough for the rider to plunge safely into and providing means to
exit the pool. The selection segment 300c rotates to select a
different slide way for the rider. In the given example there are
three possible positions for the selection segment. The selection
segment is positioned to the first position (as shown in the
figure) for the rider to end up in the first downstream slide way
604c. The first, second and third downstream slide ways 604a,b,c
may in fact be the same pool, optionally divided into sections by
using one of multiple floating safety rope(s) 607. Water jets may
be used to guide the riders in the right direction and guide them
faster to the exit. When water jets are used, safety driving lines
may not be needed.
[0056] The selection segment 300c may be supported in the joint
with the upstream slide way segment and/or supported in another
point. This may be in the extension of the rotating axis or it may
be supported in a rotation circle perpendicular to the rotation
axis.
[0057] This selection segment may be open from the top or may be a
closed tube.
[0058] The selection segment may be made of a flexible tube. This
tube may be fixed connected to the upstream slide way segment. The
end of this tube may move horizontally from a first position into a
second position and create flow paths to different downstream slide
ways.
[0059] FIG. 7 shows a slide track in a configuration with a
telescoping selection segment 300d. The example figure shows three
different exit sections. This configuration includes the upstream
slide way segment 101 and a telescoping selecting segment 300d. The
upstream slide way segment may be straight, in which case the first
section 702 of the selection segment 300d is straight too. Both of
these sections may also be curved. This sections may be horizontal
placed or may be placed under an angle. Extending from the first
section 702 is the second section which may turn into a 90 degrees
corner 703. In the first, fully extended position, the rider will
end up in downstream slide way 604c. In second position the
telescope shortens and the selected downstream slide way is 604b.
In third position the telescope is in its shortest position and the
downstream slide way is 604a. There may be more positions and exit
sections provided. This configuration may be combined with the
rotating concept explained before.
[0060] In 704 the upper section 101 slides into first section 704
of the selection segment 300d. This connection is as smooth as
possible to give the rider a smooth transition.
[0061] FIG. 8 shows a method in accordance with the invention. With
this invention a new safety problem is introduced. The issue is the
possibility of riders in the selection segment, while the selection
segment is moving. This may result in a dangerous situation. To
solve this problem a safety system is introduced. There are two
possibilities. The first one is that riders do not follow the rules
and follow each other really fast, so the time in between riders is
smaller than the time needed to move the selection segment. If this
situation occurs, the selection segment is supposed not to move.
This will result in that the riders go to the same slide way
instead of being selected by the selection segment. The second
possibility is that the selection segment is already moving and the
safety system calculates that the rider arrives before it can
complete the movement. When the safety system calculates this, the
selection segment moves to its closest position, or the safety
mechanism may be activated as described before. The letter and/or
number combinations are used for the purpose of simplicity of the
representation of the method steps. They are explained as follows:
[0062] S1: selection segment 300a,b,c,d [0063] P1: a first position
of selection segment S1 [0064] P2: a second position of selection
segment S1 [0065] S1 P/S DATA: position and speed data of the
selection segment S1 [0066] RIDER1: a first rider [0067] RIDER2: a
second rider [0068] SW1: a first downstream slideway [0069] SW2: a
second downstream slideway [0070] RIDER2 P/S DATA: position and
speed of a second rider (RIDER2) using the slide track 100 [0071]
TP1: time needed for the selection segment S1 to move to the first
position P1 [0072] TP2: time needed for the selection segment S1 to
move to the second position P2 [0073] TR2: time needed for the
second rider to move from his current position to the position of
the exit of selection segment S1
[0074] The steps are described as follows: [0075] 1001: selection
segment S1 is set in a first position P1 and RIDER1 is in a first
downstream slide way (SW1); [0076] 1002: a second rider (RIDER2) is
detected by one of the sensors in the slide track; [0077] 1003:
using input data 1004 registered by sensors at the selection
segment S1, the data comprising data on position and speed of the
selection segment S1, a time TP1 is calculated of known as a fixed
value, comprising the time needed for the selection segment S1 to
complete the movement to the first position P1; a time TP2 is
calculated or known as a fixed value, comprising the time needed
for the selection segment S1 to complete the movement to the second
position P2; [0078] 1005: Using input data 1006 registered by
sensors in the slide track 100, the data comprising data on
position in the slide track and optionally speed of the second
rider RIDER2 using the slide track, a time TR2 is calculated,
comprising the time needed for the rider to arrive at the exit of
the selection segment S1 in a second position P2; [0079] 1007: the
values of TP2 and TR2 are compared. If TP2 is smaller than TR2,
then, if selection segment S1 is not yet in the second position,
selection segment S1 is moved from the first position P1 to the
second position P2 at 1008; calculating TP1 and TP2 continues until
the selection segment S1 is in the second position P2 as checked at
1009. If the selection segment S1 is in the second position P2, the
cycle ends at 1013 and a path is created to exit the second rider
RIDER2 to a downstream slideway SW2. The process starts again at
1001, wherein RIDER2 is designated as RIDER1 and the second
position P2 is designated as a first position P1 and the downstream
slideway SW2 is designated as a first downstream slideway SW1;
[0080] 1010: If TP1 is not smaller than TP2, step 1009 follows;
[0081] 1011: If TP1 is smaller than TP2, meaning that it takes less
time for selection segment S1 to move to the first position P1 than
to move to the second position P2, the selection segment S1 is
moved back to the first position P1 at 1012. If selection segment
S1 is in position P1, the cycle ends at 1013 and a path is created
to exit the second rider RIDER2 to downstream slideway SW1. The
process starts again at 1001, wherein RIDER2 is designated as
RIDER1.
[0082] If it is calculated that the completion of the moving back
to the first position in step 1008 will take longer than the
arrival of the rider at the exit of selection segment S1, an
emergency procedure may be initiated, comprising measures such as
braking or warning the second rider, or releasing the emergency
mechanism of the selection segment S1 in order to quickly move the
selection segment to its default position.
[0083] In a first aspect of the present invention, a slide track is
provided, comprising:
[0084] an upstream slide way segment 101 arranged to transport a
rider;
[0085] a selection segment 300a,b,c,d comprising an entry arranged
for receiving the rider from the upstream slide way segment
101;
[0086] the selection segment 300a,b,c,d comprising one or more exit
sections;
[0087] a downstream slide way segment 103,602 comprising a
plurality of downstream slide ways 105a,b and 604a,b,c arranged for
further transporting the rider;
[0088] the selection segment 300a,b,c,d arranged to selectively
transport the rider through one of the one or more exit sections to
one of the plurality of downstream slide ways 105a,b and
604a,b,c;
[0089] an actuator arranged to manipulate the selection segment
300a,b,c,d, and
[0090] the selection segment 300a,b,c,d arranged to provide a
substantially continuous flow path from the upstream slide way
segment 101 to the one of the plurality of downstream slide ways
105a,b and 604a,b,c.
[0091] The advantage of this aspect of the invention is that a
smooth and safe flow path is provided for the rider. The speed of
the rider arriving from an upstream slide way and entering the
selection segment 300a,b,c,d is substantially maintained up to the
moment the rider exits the selection segment 300a,b,c,d. The
selection segment 300a,b,c,d is positioned in a first position for
a first rider and positioned in a second position for a
subsequentially arriving second rider. This allows for the use of
multiple downstream slide ways 105a,b and 604a,b,c, which
alternatingly receive a first, second, third etc. riders. This
prevents riders from bumping into each other in the same downstream
slide way. This results in a faster and safer operation of the
slide track, a higher throughput of riders and therefore an
increase of capacity of the slide track.
[0092] In a first embodiment, the selection segment 300a,b,c,d is
movably connected to the upstream slide way segment 101. This
provides a smooth flow path between the upstream slideway segment
101 and the selection segment 300a,b,c,d.
[0093] In a second embodiment, the selection segment 300a,b,c,d
abuts on at least a part of the upstream slide way segment 101
and/or at least a part of the downstream slide way segment
103,602.
[0094] In a third embodiment, the selection segment 300a,b,c,d is
rotatably connected to the upstream slide way segment 101.
[0095] In a fourth embodiment, rotatably connected comprises that
the selection segment 300a,b,c,d is arranged to be rotatable around
a rotation axis running from the entry to the one or more exit
sections. This results in an easy joint between the segments and
makes it easy to abut the segments to each other. It makes
different slide ways possible in a safe system with a substantially
continuous flow path for the rider. By positioning the axis for
example above the center of gravity of the selection segment, the
gravitational force may cause the selection segment to rotate into
the default position in a case of power loss or malfunction. This
provides an additional safety measure.
[0096] In a fifth embodiment, the selection segment 300a,b,c,d is
arranged to be moved from a first position, providing a flow path
to a first downstream slide way of the plurality of downstream
slide ways 105a,b and 604a,b,c, to a second position for providing
a flow path to a second downstream slide way of the plurality of
downstream slide ways 105a,b and 604a,b,c.
[0097] In a sixth embodiment, at least a part of the selection
segment is made of deformable material arranged to be deformed to
selectively create the flow path.
[0098] The advantages of having a deformable selection segment
are:
[0099] by reducing the number of moving parts and by having a fixed
connection between upstream sideway segment, selection segment and
two or more downstream segments, the flow path is uninterrupted by
otherwise possibly present bumps, gaps or seams between the
segments;
[0100] the selection segment is integral part of the slide track,
without a chance that the rider would fall off or out of the slide
track at or around the selection segment. This results in better
safety and less dangerous situations;
[0101] customizing of the selection segment or adjustments of
dimensions and slope in agreement with dimensions and slope of
existing slide tracks is easier.
[0102] In a seventh embodiment, the one or more exit sections are
arranged to be moved from a first position, providing a flow path
to a first downstream slide way of the plurality of downstream
slide ways 105a,b and 604a,b,c, to a second position for providing
a flow path to a second downstream slide way of the plurality of
downstream slide ways 105a,b and 604a,b,c. This results in that
more riders may be in different downstream slide ways 105a,b and
604a,b,c at the same time and makes a higher throughput and
capacity possible.
[0103] In an eighth embodiment the one or more exit section are
arranged to be telescoped.
[0104] In a ninth embodiment, the one or more exit sections are
arranged to be veered.
[0105] In a tenth embodiment, the selection segment 300a,b,c,d
comprises the downstream slide way segment 103,602. This makes it
possible to move the downstream slide way segment 103,602 together
with the selection segment 300a,b,c,d.
[0106] In an eleventh embodiment, the selection segment 300a,b,c,d
is arranged to be moved from the first position to the second
position if the first downstream slide way of the plurality of
downstream slide ways 105a,b and 604a,b,c is occupied by a
rider.
[0107] In a twelfth embodiment, the actuator is operated by
exertion of a gravitational force by the rider entering the
selection segment 300a,b,c,d. In this way no additional detection
means are necessary.
[0108] In a thirteenth embodiment, the actuator is operated by a
motor, such as an electrical motor, a hydraulic system, or a
pneumatic system.
[0109] In a fourteenth embodiment, the slide track is provided with
one or more sensors, arranged for detecting the presence of the
rider in the slide track.
[0110] In a fifteenth embodiment, the one or more sensors are
arranged to detect the speed and/or location of the rider in the
slide track.
[0111] In a sixteenth embodiment, the presence of the rider in the
slide track comprises the presence at a location of the group
comprising an entry point of the slide track; the upstream slide
way segment 101; the selection segment 300a,b,c,d; the junction
between the selection segment 300a,b,c,d and the downstream slide
way segment 103,602; the downstream slide way segment 103,602; or
an exit point of the slide track. The advantage is that by
providing means to detect the position of the rider at various
locations, a more accurate prediction is possible of the time of
arrival of the next rider, in order to safely move the selection
segment 300a,b,c,d from a first position to a second position in
time.
[0112] In a seventeenth embodiment, a resilient seal is provided
between the selection segment 300a,b,c,d and the upstream segment
and/or the downstream slide way segment 103,602. This prevents
leakage of water and making the transition between the segments
smooth.
[0113] In an eighteenth embodiment, the rider comprises a boat or
raft arranged to carry one or more individuals. By carrying
multiple individuals in a boat for example, the capacity is
increased.
[0114] In a second aspect of the present invention, a method is
provided for operating a selection segment 300a,b,c,d in a slide
track, the slide track, comprising:
[0115] an upstream slide way segment 101 arranged to transport a
rider;
[0116] a selection segment 300a,b,c,d comprising an entry arranged
for receiving the rider from the upstream slide way segment
101;
[0117] the selection segment 300a,b,c,d comprising one or more exit
sections;
[0118] a downstream slide way segment 103,602 comprising a
plurality of downstream slide ways 105a,b and 604a,b,c arranged for
further transporting the rider;
[0119] the selection segment 300a,b,c,d arranged to selectively
transport the rider through one of the one or more exit sections to
one of the plurality of downstream slide ways 105a,b and
604a,b,c;
[0120] an actuator arranged to manipulate the selection segment
300a,b,c,d, and
[0121] the selection segment 300a,b,c,d arranged to be moved from a
first position arranged to transport the rider to a first
downstream slide way, to a second position arranged to transport
the rider to a second downstream slide way, wherein
the selection segment 300a,b,c,d is moved to the first position, if
it is calculated that the time needed to complete the movement of
the selection segment 300a,b,c,d to the second position is longer
than the time it takes for the rider to arrive at the exit section
of the selection segment 300a,b,c,d to the second downstream slide
way. This ensures that the selection segment 300a,b,c,d doesn't
move to a position when a rider arrives too soon. If the rider
arrives too soon, this may lead to the rider exiting the selection
segment 300a,b,c,d while the selection segment 300a,b,c,d is still
rotating, causing a dangerous situation.
[0122] In a first embodiment of the second aspect of the invention,
the calculation is based on determining a speed and a location of
the rider at one or more locations in the upstream slide way
segment 101, using one or more sensors, and calculate the time
needed for the rider to arrive at said exit section.

BEST MODE FOR CARRYING OUT THE INVENTION
[0125] The best mode for carrying out the invention is to provide a
slide track with a rotatable selection segment between an upstream
slide way segment and a downstream slideway segment, comprising
multiple slide ways, wherein a continuous flow path is provided to
a selected slide way. To ensure safe operation, multiple sensors
are located in the slide track for detecting the speed and position
of the rider. The selection segment rotates only from a first
position to a second position if the rotation can be completed in
time before the arrival of the rider at the exit of the selection
segment.
