Definitions

  • the present invention relates to an amusement ride passenger unit.
  • the present invention as specified in the preamble of claim 1, relates to an amusement ride passenger unit which has a passenger receptacle and a passenger restraint device, the passenger restraint device comprising a restraint element which can be changed in position and a lockable hydraulic adjuster acting on this, which in turn comprises a Includes cylinder-piston unit and a hydraulic accumulator.
  • the DE3237684 A1 discloses an amusement ride passenger unit according to the preamble of claim 1.
  • passenger restraint devices are available for safety reasons, by means of which the passengers are fixed to the passenger seat they are occupying in such a way that they cannot leave this passenger seat (seat, lying area, standing room, etc.).
  • the passenger restraint device also restricts the freedom of movement (immobilization) of the passenger concerned.
  • EP 3081273 A1 WO 2007/136245 A1 , WO 2006/053591 A1 , EP 1912715 B1 , US 9744930 B2 , US 4531459 A , US 5129478 A , WO 01/74626 A1 , WO 99/21737 A1 , US 2010/0307288 A1 and US 2008/0149017 A1 .
  • Common restraint elements are, for example, restraint bars, by means of which the passenger is fixed on the shoulders, chest, back, stomach, hips and / or legs, for example.
  • Such restraint bars or other restraint elements can in particular be pivotably attached to the structure of the passenger unit that also includes the passenger receptacle in such a way that they can be locked in several different positions to adapt to the individual body size of the passenger in question.
  • the locking function is typically based on the fact that hydraulic fluid is tightly locked in a hydraulic cylinder working space, the volume of which changes with the position of the retaining element. This allows the retaining element to be locked continuously in different positions.
  • the hydraulic cylinder can optionally be part of a hydraulic adjuster, which has a further function in addition to the blocking or locking function for the retaining element, namely that it is suitable and designed to actively open the retaining element - after it has been unlocked. In all of the passenger units of the Ride the restraint bar or other restraint elements are opened simultaneously and without the assistance of the passengers by the associated adjuster, which enables a quick and smooth passenger change.
  • the adjuster comprises, in addition to the - then typically double-acting - hydraulic cylinder, a hydraulic accumulator that stores hydraulic fluid under pressure, is charged by hydraulic fluid displaced from the hydraulic cylinder when the retaining element is closed and - with the corresponding valve position - the hydraulic cylinder with the opposite flow direction in the sense of opening the Retaining element acted upon.
  • the present invention has set itself the task of further improving the prior art set out above in terms of safety.
  • amusement ride passenger unit of the generic type that the hydraulic accumulator and the cylinder-piston unit of the hydraulic adjuster form a structural unit by the cylinder of the cylinder-piston unit and a cylinder of the hydraulic accumulator arranged next to and parallel to this are part of an integrated cylinder assembly which comprises a common closure cover on each of the two end faces.
  • amusement ride passenger units can be realized in which the hydraulic adjuster is extremely compact despite the provision of high locking forces.
  • the hydraulic accumulator has a cylinder that extends parallel to the cylinder of the cylinder-piston unit and at least essentially over its entire length.
  • the hydraulic accumulator can be made comparatively slim.
  • the hydraulic adjuster can be ideally accommodated within the passenger unit in terms of safety, i.e. in a place where it is optimally protected from damage that affects function and reliability, while at the same time both the small size and the possibility of optimal accommodation Minimize the risk of injury to the passenger.
  • the possibility of a comparatively closed construction also contributes to this, i. H. the absence of protruding parts and / or gaps in which objects can get caught.
  • the hydraulic adjuster of the passenger unit according to the invention is particularly suitable for a modular design. Adjusters that are mirror-inverted, for example, can be provided with particularly little effort. The same applies to adjusters that differ only with regard to the piston blocking direction (ie blocking against retraction or against extension of the piston rod with free movement in the opposite direction), but otherwise identical are. With a suitable design, the adjuster can even be retrospectively converted from one version to another through a simple and problem-free intervention.
  • the hydraulic accumulator used in the hydraulic adjuster of the passenger unit according to the invention - as part of an integrated cylinder assembly including the cylinder of the cylinder-piston unit - can in a preferred embodiment be designed as a spring accumulator so that the hydraulic fluid stored in its cylinder is by means of a spring is kept under pressure, the hydraulic space storing the hydraulic fluid and the spring space housing the spring being separated from one another by a separating element.
  • a spring accumulator used in the hydraulic adjuster of the passenger unit according to the invention - as part of an integrated cylinder assembly including the cylinder of the cylinder-piston unit - can in a preferred embodiment be designed as a spring accumulator so that the hydraulic fluid stored in its cylinder is by means of a spring is kept under pressure, the hydraulic space storing the hydraulic fluid and the spring space housing the spring being separated from one another by a separating element.
  • Various devices that are suitable for absorbing, storing and releasing energy come into consideration as springs.
  • the spring is implemented by a mechanical
  • the comparatively elongated construction of the hydraulic accumulator can be used in an optimally functional manner due to its particularly slim cylinder (see above).
  • the cylinder assembly of the hydraulic adjuster comprises a section of an extruded double tube profile.
  • the cylinder assembly by the cylinder of the cylinder-piston unit and the cylinder of the hydraulic accumulator mutually reinforce each other, also withstand particularly strong or violent mechanical stresses without damage, and that with a particularly low weight, which is in view of the z. T. quite considerable acceleration forces to which the elements of the passenger restraint device are exposed, in turn, proves to be very advantageous.
  • the Hydraulic accumulator comprises a gas spring, ie the spring space, which is preferably delimited by a piston or a bubble arrangement, accommodates a compressed gas filling in a gas-tight manner, the gas spring having the further advantage that its operating characteristics are due to the changing position or orientation in space and / or the rapidly and rapidly changing kinetic Relationship is only minimally affected.
  • a switching plate is provided on the front side of the cylinder assembly - with a line and valve arrangement that hydraulically interconnects the hydraulic accumulator with the cylinder-piston unit, as well as an electrical switching interface.
  • the hydraulic accumulator is designed as a spring accumulator, in particular as a gas spring piston or gas spring bladder accumulator, the hydraulic chamber of the hydraulic accumulator is particularly preferably adjacent and the spring chamber of the hydraulic accumulator is arranged at a distance from the circuit board.
  • the cylinder-piston unit can be designed as a differential cylinder and, in an unlocked floating position, both the piston working chamber and the piston rod working chamber of the differential cylinder can be pressurized from the hydraulic accumulator via the line and valve arrangement.
  • both the piston working chamber and the piston rod working chamber of the differential cylinder can be pressurized from the hydraulic accumulator via the line and valve arrangement.
  • the above-mentioned line and valve arrangement accommodated in the circuit board preferably comprises one, i. H. at least one non-return valve, which in a safety position allows a flow from the piston working chamber of the differential cylinder to its piston rod working chamber, but prevents it in the opposite direction.
  • the restraint element can be operated intuitively by manually moving it to rest against the passenger's body until it is securely fixed, the restraint element then remaining in this position without further ado, due to the non-return valve that is effective in the safety position .
  • Such intuitive operation is also an important aspect that promotes safety.
  • Those line and valve arrangements are particularly advantageous in which the safety function described by exactly one, i. H. a single check valve is guaranteed, not only in terms of costs and installation space, but also in terms of safety.
  • the line and valve arrangement can comprise a blocking valve arrangement which, in a blocking position, locks hydraulic fluid in the differential cylinder when the piston of the differential cylinder is extended.
  • the restraint element in its completely open - and there blocked - position is suitable as an entry and / or exit aid, on which the passenger can find support. Accidents that were caused in the past by a passenger believing this give hold, when getting in or out, grabbing the restraint bar or other restraint element, but this has given way, can be avoided in this way.
  • the adjuster comprises a piston position sensor.
  • a piston position signal generated by the piston position sensor can be evaluated in various ways in an electronic circuit that communicates with the piston position sensor via a control interface such as an SPI bus.
  • the direct monitoring of the piston of the cylinder-piston unit of the adjuster which is possible by means of the piston position sensor and the evaluation circuit, to determine whether its position within the cylinder remains the same or changes, is a further substantial increase in safety.
  • conscious manipulation in particular by holding onto the retaining element
  • the piston position sensor has a spindle which extends parallel to the cylinder axis and is mounted axially fixed and rotatable relative to the cylinder, with a threaded section which plunges into a cavity of the piston and has a coarse thread, which cooperates with a corresponding spindle nut arranged on the piston.
  • Axial movement of the piston causes the spindle to rotate.
  • Such a rotation of the spindle is detected by means of a pick-up, which is preferably designed as a contactless rotary encoder. A change in the piston position can thus be reliably detected by means of a particularly compact device.
  • the evaluation circuit - this is preferably a structural component of the adjuster, but can optionally also be provided remotely for this purpose - can, but does not necessarily have to be continuously determine the absolute position of the piston in relation to the cylinder of the cylinder-piston unit. Rather, it is primarily sufficient to limit oneself to monitoring, independent of the respective absolute position, solely of a possible movement of the piston relative to the cylinder of the cylinder-piston unit; and such movement monitoring can also be limited to specific points in time or time ranges within the respective operating cycle of the amusement ride, in which case an evaluation can be omitted during the passenger change.
  • the monitoring aimed at the detection of piston movements takes into account the fact that the individual position in which the restraint element must remain fixed during the relevant driving cycle by means of the adjuster can change from driving cycle to driving cycle, because they are e.g. B. depends on the body dimensions of the respective passenger.
  • the information as to whether and, if applicable, how (during the evaluation cycle or the evaluation phases) the piston of the cylinder-piston unit moves relative to its cylinder or not, can be derived from the piston position signal in various ways, such as detected clocked by comparison Piston position signals by determining the piston speed by means of differentiation (derivation) of the continuously recorded piston position signal according to time, by determining the piston acceleration by means of double differentiation (derivation) of the continuously recorded piston position signal according to time, or the like.
  • the evaluation of the piston position signal can possibly also relate to the direction of movement of the piston relative to the cylinder of the cylinder-piston unit, in particular via the direction of rotation of the above-mentioned spindle; because a further pulling of the restraint element by the passenger on his body in order to ensure an even better fixation in or on the passenger receptacle is fundamentally to be assessed differently than a movement of the restraint element in the opposite direction, i.e. H. a (creeping) opening of the retaining element.
  • the evaluation circuit not only determines possible movements of the piston of the cylinder-piston unit while the ride is in motion, but also processes information on the absolute position of the piston, then - as an additional safety aspect - it is possible to check whether all Passenger units of the amusement ride, the respective restraint element are in a closed position at the beginning of the relevant driving cycle (within a range that takes into account the typical body dimensions of passengers).
  • the piston position sensor communicates with an operating data memory in such a way that piston position signals are stored there so that they can be called up.
  • the operating data memory is a structural part of the respective adjuster.
  • a central operating data memory in which the operating data of several adjusters of the amusement ride in question are stored may also be considered.
  • the individual number of uses of the respective passenger unit can be recorded from the data stored in the operating data memory. This allows service, maintenance and care work to be carried out on the individual passenger unit depending on the intensity of use, which is advantageous from both a cost and a safety point of view.
  • the amusement ride passenger unit which is partially only schematically illustrated in the drawing, comprises a passenger seat 1 and a passenger restraint device 2.
  • the passenger seat 1 is designed as a seat 5 mounted on a base structure 3 of the ride, namely on a seat support 4.
