Description

Has the Fairground attraction that is suspended from two people on the rotatable arm that is parallel to each other

Technical field

The present invention relates to a kind of Fairground attraction, comprise at least two that be parallel to each other and separately around the rotatable arm of an axis, and suspention has at least one people between this two arm.This Fairground attraction is known, and its name set is " windscreen wiper ", refers to the motion of passing through the windscreen wiper that connecting rod interconnects of old-fashioned commercial car and bus.

Background technology

This known attraction is found in the amusement park and exists with fixed form, and also be used in the recreation ground in the mode that can be disassembled and transport, it comprises two vertical masts, each root mast side thereon has a rotating shaft transverse to it, and around each root rotating shaft one rotatable arm is arranged.The end of these two arms connects by crossbeam or gondola, and this crossbeam or gondola are suspended from the arm end pivotally, and are formed with a plurality of seats thereon.The seat is parallel to the rotating shaft location of these arms, so that the passenger stands laterally to rotatablely move and from overlooking the public of suction device front here.In the back of turning arm and gondola, be placed with background usually, thereby the mechanical part of this suction device can be hidden and can't see with decoration and illumination.What be positioned at the gondola front is platform, and the passenger can climb up this platform and go down from this platform.

Summary of the invention

Although such Fairground attraction was once once very popular, the reason of part is the contact between the passenger and the public,, particularly owing to the one-sided property result of this motion, this no longer is considered to stimulate especially, even under high-speed motion.Therefore, the purpose of this invention is to provide a kind of Fairground attraction of the above-mentioned type, with respect to traditional suction device, it more stimulates and can produce speed and stronger freely sensation.According to the present invention, this realizes that by a kind of like this Fairground attraction wherein the rotation of arm and horizontal plane are angled.By arm is rotated around non-level axis, in fact the people or the gondola that are loaded with the passenger are within it standing three-dimensional motion, rather than the two dimensional motion of known " windscreen wiper " suction device.Therefore can realize better sensation, even under than the lower speed of conventional " windscreen wiper " suction device, move to motion.

When people can also be introduced the extra free degree, thereby can make the motion of people more exciting when the axis that arm is coupled together pivot.Here, for the load on the limiting structure as much as possible, this suction device preferably has the device that is used to decay and/or fetters the people pivoting action.

In order to set up enough free spaces, to allow the uncrossed motion of people, each arm preferably has horizontal with this arm substantially in the lump strut that is positioned near its end, and people is outstanding thereon.For the needed space of motion, people preferably also is suspended from the place, outer end near it.

In order to protect the passenger, when particularly the leg that does not have pedal and a passenger in people freely dangled, people can have baffle plate in each outer end.

Just as known " windscreen wiper " suction device, the rotating shaft of each arm can support by mast, and its middle mast also can be connected by framework.

For Fairground attraction can easily be transported, framework is advantageously embodied as the chassis of rolling and has the device that it is connected with tractor.In this case, arm is preferably taked the form of separating, and each several part is collapsible or telescopic, so that the size that limits suction device as much as possible is to be used to by highway transportation.As mentioned above, when people was suspended from strut, these struts were therefore preferably folding.

The result that people is arranged between the arm is, in the part of an arm relative to each other is being different from the plane of part of another arm when removable, and the most probable compact-folded position that can realize suction device.

For simplify the passenger about, Fairground attraction preferably has platform, it can move along short transverse when arm occupies vertical basically resting position.This is a relative simple proposal that can low-cost realize.

This purpose also can realize by another technical more complicated mode, for example can move on short transverse when arm occupies vertical basically resting position when people.When rotating shaft was supported by mast, this top that can work as each root mast of supporting rotating shaft was connected to the bottom of mast so that realize in simple mode when the axis of accumbency pivots.Have optimum stability when making people climb up and leave, this suction device can be provided for making people stationary device during the pivoting action of mast top and rotating shaft.When mast top had been pivoted back to their operating position, the swing of people only need realize immediately by discharging these fixtures.

In order to make the minimum in its use that loads on the Fairground attraction, preferably be provided with the device of actuating arm with the intersync mode rotation.When the drive unit that is used for each arm comprises motor, and motor is when connecting by principal and subordinate's annexation, and this driven in synchronism can realize in reliable mode.In addition or alternative, the synchronism of arm motion can strengthen or realizes by at least one stabiliser bar that is used for linking arm.This bar can be used for limiting the load on the people, particularly when motor breaks down.

The specific embodiment

Fairground attraction 1 comprises framework 2, is placed with two masts 3 thereon.Each mast 3 has the gear ring 5 that defines rotation R at its top 4 upper supports.According to the present invention, when Fairground attraction 1 running, the angle between each root axis R and the horizontal H is α ₁

Can be suspended from each mast 3 by gear ring 5 around the arm 6 of axis R rotation.Each arm 6 almost is connected to mast 3 to be used for rotation at its half place of length, and have a free end 7 and opposite end 9, and wherein counterweight 8 is fixed to free end.People 10 is suspended between the end 9 of two arms 6.

People 10 is by forming as the crossbeam 11 of backrest, and a plurality ofly is connected to this crossbeam 11 by handrail 13 mutual separated seats 12.A plurality of head support 14 also are installed on the crossbeam 11.Seat 12, handrail 13 and head support 14 define the seat that is used for the passenger together.Here people 10 does not have pedal, so passenger's leg is freely to hang down.This has increased sensation.Baffle plate 15 is fixed to the two ends of people 10, is used for preventing that the passenger's of outer seats leg from contacting with arm 6.Here baffle plate 15 is made by transparent material, and plastics for example are so that can not hinder passenger's the visual field.Owing to will illustrate hereinafter, baffle plate 15 is longer relatively.

People 10 is not the end 9 that directly is suspended from arm 6, but is suspended from substantially two struts 16 perpendicular to arm 6.Thereby created certain space between arm 6 and people 10, this possible motion for people 10 is necessary.For the same reason, people 10 is from its outer end suspention, and this gondola with traditional " windscreen wiper " suction device is different.

People 10 is suspended between the strut 16 pivotally.People 10 under any circumstance must pivot around the axis that is parallel to strut 16, so that can follow rotatablely moving of arm 6.In addition, in an illustrated embodiment, people 10 can pivot around the strut 16 interconnective axis A that make two arms 6.For these two kinds of pivoting actions, can utilize single ball-and-socket joint, but in an illustrated embodiment, in each example of people 10 two

independent joints

17,36 are set.First joint 17 between people 10 and the strut 16 provides the motion around axis A, and the motion that the gantry post 36 between strut 16 and the arm 6 is responsible for around the axis of strut 16.

In order to prevent the uncontrolled movements of people 10, can be provided for decaying and/or fettering the device that moves pivotally.Therefore, this structural load can be limited, so that suction device 1 can have lighter structure as a whole.Therefore motion more at a high speed can be allowed, thereby sensation can be further strengthened.These decay and/or restraint device are described in detail hereinafter and are shown.

Two arms 6 all are driven, so that they rotate synchronously around axis R.In an illustrated embodiment, for this purpose, each arm 6 is provided with its motor, and this motor is embedded in the housing 18 at top 4 of mast 3.These two motors for example connect into main motor by electronic installation and from motor, so that they are worked in identical mode.Therefore, can prevent on this structure, inappropriate load particularly on people 10, occur.Arm 6 also selectively couples together by the stabiliser bar (not shown), so that strut 16, a kind of replacement scheme in the long path of the power of joint 17 and people 10 are provided via gantry post 36.

Platform 28 is formed on the front portion of Fairground attraction 1, and this platform is separated by fence 29 and is used for about the passenger.Between platform 28 and framework 2, also can be formed with step-like lid 34, on the one hand can hide framework 2 it be cannot see, can make the mechanical part of employee in addition near Fairground attraction 1.Decorated and illuminated wall 35 also can be formed on the back of framework 2, is used for visually isolating Fairground attraction 1.

To climb up and leave in order to simplify, people 10 can by from when running its extreme lower position that can arrive move more downwards.In an illustrated embodiment, this can realize by inclined arm 6 fully, thus the angle α between arm 6 and the horizontal H ₂Become littler during than running.For this reason, the top 4 of each root mast 3 is connected to its bottom 31, is used for pivoting around the axle 30 of accumbency.In mast foot 31, also be provided with the hydraulic cylinder (not shown), its upper end is bonded on the top 4 by axle 32.As making that the motor of arm 6 rotation, the hydraulic cylinder in two masts 3 interconnects again, so that two arms 6 tilt synchronously.Also be provided with such device, only can when arm 6 is still in their upright position and stops rotation, be started to guarantee this banking motion.

As described, baffle plate 15 is taked relatively long form in the both sides of people 10.Under the people in the people position, the bottom margin 33 of baffle plate 15 relies on the platform 28, so that people 10 can not move in the reduction of people 10.In the people position, as the result that arm 6 tilts, people 10 slightly tilts to the rear portion around axis A with respect to strut 16 under last people.People 10 is fixed on this position by brake or lock (not shown).

In the alternative embodiment of Fairground attraction 101 (Fig. 7), to climb up and leave in order to simplify, not that people 110 can move down, on the contrary, be that the part 137 of platform 128 can move up.Platform 128 here forms by standing part 138 and part 137, and this standing part 138 has been placed on the ground G certain distance and can be approaching via step 139 from both sides, and part 137 can move and also be embodied as step on short transverse.In an illustrated embodiment, this step-like terrace part 137 relies on two support arms 140, and wherein this two support arm is pivotally connected to framework 102 to suction device 101 by hinge 141.

In the operation process of suction device 101, support arm 140 and therefore step part 137 is folding downwards is not so that the motion of turning arm 105 and people 110 can be hindered.When arm 106 and people 110 are brought to lower position shown in stopping at, the last people servant position shown in the step part 137 of support arm 140 and platform 128 upwards is folded to once more by the driving element (not shown).For stabilize people carrier 10, the bottom margin 133 of baffle plate 115 relies on the terrace part 137 that is in this position once more.

In this way, the mast top of technical sophistication and therefore relatively costly tiltable embodiment can be omitted.

The Fairground attraction 101 of this embodiment also shows the device 142 that is used to decay and/or fetters the pivoting action of people 110.These decay and/or restraint device 142 also are to be specifically designed to prevent that people 110 whole circles from changeing, take the form of hydraulic cylinder here, its end 143 all is being bonded on the strut 116 under each situation, and its another end 144 is bonded on the lever 145 that is connected to joint 117.

Yet for suction device 101 being folded into compact form, mast 103 is taked the form of separating and is had hinge 130 in this embodiment.

As described, mast 3 is positioned on the framework 2, and in an illustrated embodiment, framework 2 is embodied as the chassis of rolling.The form of trailer is taked on this chassis here, and has the part 19 that supports mast, and the curved neck joint 20 with king bolt 21, and the chassis that is used for rolling is connected to tractor (not shown) (Fig. 8).This chassis has three axles 22.

In the use of Fairground attraction, for framework 2 is placed on the ground G with stable manner, provide two pairs of crane arms 23,24, their end is installed on the framework 2, and the free end of each crane arm all relies on the ground jack 25.Here, two crane arms 23 all are connected to frame part 19, frame part 19 is used for mast 3 is supported on the front side of Fairground attraction 1, people 10 is positioned at this front side, and in two crane arms 24 at rear portion each forms by underarm 24L that is connected to framework 2 and the upper arm 24U that is connected directly to one of mast 3.Consider and will come transport of fairground attraction 1 by highway, crane arm 23,24 is taked folding form.In an illustrated embodiment, anterior crane arm 23 upwards pivots on the hinge of level, and rear

portion crane arm

24L, 24U can be switched to the position that is parallel to framework 2 on vertical hinge.For this motion, crane arm 23,24 also can be provided for example hydraulic pressure or thermo-mechanical drive (not shown).

Arm 6 and strut 16 also are folding in an illustrated embodiment.For this reason, two forms that arm 6 is taked to separate, and standing part 6F and moveable part 6M interconnect by hinge.Strut 16 also is connected to the gantry post 36 at 9 places, end of arm 6 by hinge 27.Set up enough spaces that is used for people 10 in order to make when strut 16 folds, arm portion 6M can move in different planes.In an illustrated embodiment, the hinge 26L of left arm 6 is positioned at the front surface of this arm, and the hinge 26R of right arm 6 is positioned at its side surface.In the folding position, the part 6F of left arm, 6M are positioned at front each other, and those parts of right arm 6 are adjacent one another are.Owing to be projected into hydraulic cylinder in the mast foot 31, so mast top 4 turns forward in transportation, to such an extent as to make rotation R substantial horizontal, and the gear ring 5 that therefore has arm 6 thereon is arranged in vertical plane.

The operation of Fairground attraction 1 will be described now.When the passenger has climbed up simultaneously people 10 and is under the people people position (Fig. 3,6), the mast top 4 that has arm 6 thereon is pivoted back to operating position and rotation and hinders and be released (Fig. 2,5).Motor is started subsequently, thereby arm 6 is set to the parallel and synchronously rotation around rotation R.Under first situation, the direction of rotation of motor can be periodically reverse, so that arm 6 is carried out oscillating motion, and its displacement becomes big gradually.In case people 10 has arrived uppermost position (Fig. 1,4), motor can continue rotation along same direction, moves thereby can obtain continuous rotation.Peak place in people 10 can be reverse once more.If the moment of torsion of motor is enough high, directly rotate to uppermost position so that have the arm 6 of people 10 thereon, above-mentioned oscillating motion is certainly saved.

Because rotation R is arranged to and the angled α of horizontal H, thus arm 6 in plane inclined, move so that the motion of people 10 comprises three components, i.e. transverse movement, motion from front to back and moving up and down.Therefore in relatively low rotary speed, promptly about per minute ten to 30 changes, and preferred per minute 15 to 25 changes, and more particularly per minute 22 changes, and can obtain the very big sensation to speed.Because these low rotating speeds that require, the motor with relatively low power can be satisfied the demand, and is limited thereby the cost of Fairground attraction 1 can keep, and its structure also can be taked lighter form relatively simultaneously.

Except the motion that the rotation people 10 owing to arm 6 spontaneously stands, also might produce extra oscillating motion around axis A.For this reason, can use brake or lock, so that people 10 is fixed in people's process under last people.When this brake or be locked in that arm 6 tilts to get back to operating position once more and when not discharging immediately, the obliquity that people 10 remains fixed in its backward.By discharge this brake or lock at last when rotatablely moving of arm 6 begins, people 10 will be returned at the lower edge direction pivot forward that influences of gravity, thereby oscillating motion can begin immediately.

As described, this oscillating motion can be attenuated on the other hand, thus the higher rotating speed of arm and therefore speed bigger felt to have become may.

By using relatively simply device, according to Fairground attraction 1 of the present invention; Therefore 101 can provide motion, speed and special sense freely.

Although the present invention has provided description in the above according to exemplary embodiment, obviously the present invention will be not limited thereto.The inclination angle of rotation R for example also can change in operation process, thereby arm 6 can move in different inclined planes at every turn.People 10 also can be provided with driver, thereby can be reinforced around the oscillating motion of axis A, and selectively, around the complete rotation of this axis even also be possible.Under the sort of situation, its structure must be reinforced and strengthen.In addition, the motor of two synchronous workings can be replaced by single motor, and this single-motor drives two arms 6 by suitable transmission device.

The shape and size of axle 3, arm 6 and people 10 also can further change, and can use more or less mast 3 and arm 6.Fairground attraction 1 can have the people 10 more than, for example is suspended from two people of arm 6 with so-called theatre arrangement.In addition, the end 7 of arm 6 also can have the suspension arrangement that is used for people, to substitute counterweight 8.People moves to the people and the servant position also can be carried out in a different manner, for example by moving down strut 16 or the telescopic ground mast foot 31 of withdrawing.Also can make different selections for the driving of different elements and the folding mode that is used to transport.

In addition, when suction device 1 was used to the amusement park, framework 2 can certainly have fixing form.Therefore can omit for example device of crane arm and so on, arm 6 and strut 16 just need not to take folded form simultaneously.At last, do not have independent framework also to be fine in this case, and mast can directly be placed on the ground.

Therefore scope of the present invention is only limited by following claim.
