Abstract

The gondola (10) of a swingboat turning full circle and accommodating a plurality of passengers is suspended so that it oscillates between two parallel booms (5). The booms (5) are pivotally mounted about an axis (7) running horizontally between two vertical columns (2, 3) and can be motor-driven. The passenger gondola (10) is cardan-suspended on the ends of the booms (5). The booms (5) are synchronously driven and for this purpose are coupled together by a shaft (7). The cardan suspension of the passenger gondola (10) is achieved by means of pendulum arms (10a) on shafts (25) running transversely to the pendulum axis (11). The deflection of the shafts (25) in relation to the booms (5) is limited to a small angle. <IMAGE>

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial applications]

The present invention relates to two parallel members rotatably supported about an axis extending between two vertical support members arranged on a gantry and driven by a motor. "Outrigger" throughout.
The present invention also relates to a flipping swing in which a passenger gondola having a passenger seat in a row extending in parallel with the axis of the outrigger is suspended at both ends in a pendulum and a driving method thereof.

2. Description of the Related Art

As a vehicle of this type, a vehicle that gives a strong impression to passengers during operation and that can be quickly and easily assembled and disassembled has already been proposed (DE-A-33 21 599).
Fast and easy assembly and disassembly is achieved by providing a support member that can be extended and retracted on a gantry and pivoted in a hinged manner. On the other hand, impressiveness caused by the operation corresponds to the fact that a normal flipping swing is lifted while swinging freely on the outrigger. Known somersault swing (DE-A-33 21 599 above)
In p.10 middle line. Some have already found that somersault vehicles are not really feasible. In order for a passenger gondola to flip over, the passenger must be exposed to too high an acceleration in a row of seats located far below the axis of rotation, so that a flipping motion can be tolerated from a medical point of view. There is no. In contrast, the flipping swings of the present invention provide an interesting embarkation for the passengers by exposing the passengers to excessive acceleration (albeit at high acceleration) by relatively simple means using ordinary flipping swings. You can have experience. At this time, the individual passengers are each independently seated in the passenger gondola similarly to the vehicle described in EP-B1-140-230 (note that this EP-B1-14 )
Vehicles 0-230 are those in which the gondola cannot be turned around. )

[Means for Solving the Problems, Functions and Effects]

According to the present invention, the headrest of the passenger seat of the passenger gondola is arranged at a position not far from the swing axis of the gondola. This prevents the passenger's head and neck from being exposed to excessively high accelerations by simple means. Here, the centrifugal force of the gondola itself is added to the centrifugal force of the outrigger as the passenger gondola flips over. In the descent state, the gravitational force of the earth is further applied. As a result, total acceleration is calculated to be dangerous for the entire neck, which is perpendicular to the spine (whiplash effect). Therefore, an arrangement is acceptable in which the horizontal component of the distance from the rocking axis to the head is relatively short while considering that the center of gravity of the entire gondola on which the passenger is riding is appropriately separated from the rocking axis. In comparison, the vertical component of the distance plays little role. If the passenger's head is positioned somewhat below the pivot axis, the centrifugal force associated with the flip will not exert any dangerous compression on the spine. The arrangement of the head rest in the seat near the pivot axis can be realized in various ways. If the rows of seats are oriented in the same direction and one is arranged stepwise behind the other, the distance of the back row seats from the rocking axis can be greater than the front row seats in the viewing direction. , Should also be larger. This is because the headrests in the rear row face toward the pivot axis, and the head of the passenger sitting in the seat is pressed against the headrests during somersaults. On the other hand, the front row seats receive a force such that the swinging shafts behind the front row headrests and the passengers slightly pitch (turn forward) in the case of somersaults. Need to be placed in However, it is also possible to arrange the two rows of seats symmetrically, so-called back-to-back, so that the pivot axis passes between (or above) the head rest. It is also desirable to provide a locking device on the bearing of the pendulum of the passenger gondola (on the pendulum arm), which can fix the passenger gondola at a specific angular position with respect to the outrigger. This type of arrangement enables the boarding cycle described below. In particular, it is desirable that the locking device comprises a brake disposed in the outrigger concentrically with respect to a brake drum mounted on a bearing part on the gondola side. This not only allows the gondola to be locked in any angular position relative to the outrigger, but also, depending on the braking force when desired or required, the passenger gondola To affect the rocking (pendulum movement) of the body. The point improved further in this new flipping swing is that each pendulum arm of the passenger gondola is held in a cardan joint type on a shaft attached to the outrigger by an axis extending transversely to the rotation axis of the outrigger, It can be tilted by a certain acute angle with respect to the outrigger. This avoids stress on the passenger gondola having the support members, outriggers and pendulum arms. This stress is caused by an assembling error generated when assembling the flipping swing as a vehicle, and cannot be avoided. Here, the angle at which each pendulum arm is inclined is fitted to the coaxial projection of the shaft, and
It is limited by an axially biased annular rubber member which is surrounded by a pendulum arm. The annular rubber member is radially expanded by being urged in the axial direction, causing friction with respect to the coaxial protrusion of the shaft and the pendulum arm, and as a result, damping the swing of the passenger gondola. Work. At the same time, this annular rubber member is formed on the passenger gondola as a result of somersaults,
Attenuate load fluctuations due to relative movement of passengers. Similarly, the stress can be averaged by the following means. That is, one of the outriggers is
The outrigger is divided laterally with respect to a radial direction extending vertically, and the divided distal end portion of the outrigger is rotated around an axis extending in a direction transverse to the rotation axis of the outrigger. It is possible to pivot by a certain acute angle with respect to the axial part. Finally, the following features are advantageous for somersault swing vehicles mounted on a gantry. That is, a water tank comprising a plurality of annular members that can be fitted into each other like a telescope or vertically contracted coaxially for loading the components of the flip swing on the gantry, On the inside, while the water tank is in the extended state, the annular member at the top is lined with each annular member in the extended state, while the annular member is in the compressed and empty state. , A telescopic container that folds with the aquarium. In this case, when the water tank is empty, the total height of the water tank does not exceed the allowable height in the operating state, and a device for storing a required amount of water (that is, a water tank)
Can be mounted on the gantry with a relatively small area. Furthermore, the invention extends to a special driving method for this type of flipping swing. In this driving method, at the beginning of an operation cycle, the outrigger is tilted so as to form an acute angle with respect to the vertical downward direction against the direction of forward rotation, and the passenger gondola still suspended vertically with respect to the outrigger. After locking the outrigger, the outrigger is rotated forward with the passenger gondola tilted forward with respect to the outrigger, and the center of gravity of the gondola is directly above the swing axis just before the outrigger reaches the top dead center. The gondola is unlocked when passing through. This last-mentioned method leads to the passenger gondola being tilted forward and down before reaching the head-over position (upside down). The gondola swings about the swing axis, and at the same time is overtaken by a certain amount by the rotating outrigger. As a result, the passenger gondola will perform somersaults without any other influence and without leaving the platform. Depending on the driving speed (rotation speed) of the outrigger, the flow of the flipping process can be temporally and spatially influenced. As a result, the next somersault did not occur,
Or only the second somersault occurs. Also,
With the help of the brake, the passenger gondola can be locked to the outrigger. Such a brake
Used to have an immediate effect on the rocking process.

【Example】

FIGS. 1, 2, and 3 show a vehicle according to an embodiment of the present invention as viewed from the front, side, and top, respectively. As shown in FIG. 1, a gantry (platform) 1 is provided with two vertical support members 2 and 3.
A hub 4 of an outrigger 5 is provided at each upper end of the vertical support members 2 and 3.
Is pivotally supported. The hub 4 is an electric motor 6
, The motor is driven to rotate forward or backward at a predetermined rotation speed. The two rotational drives are connected to each other by a cardan shaft 7. On the opposite side of the hub 4, the outrigger 5 has a balancing portion 5a to which a balancing weight 9 is attached. These counterweights 9 are for passenger gondola 10 when their total weight is half full (when half of all seats are occupied by passengers).
Is preferably designed to match the total weight of The free end of the outrigger 5 has a shaft extending parallel to the shaft 7.
A passenger gondola 10 is pivotally supported so as to be able to swing freely around 11. Actually, the pendulum can be swung by a pendulum arm 10a whose dimension is shorter than that of the outrigger 5. As shown in FIG. 6, a brake 33 is attached to each bearing 11a, and the swing of the riding gondola 10 is affected by the brake 33, or the pendulum arm 10a is predetermined with respect to the outrigger 5. Or locked at an angled position. 13 rows of seats for passengers
The 12 are arranged stepwise at different heights in the passenger gondola 10, and in practice each row 12 is arranged to extend parallel to the shaft 7. The seat 13 is arranged with respect to the swing shaft 11 as shown in FIG. The seat 13 in the rear row 12 has a headrest 14 (attached to the stationary gondola 10) at the same height as the shaft 11 and horizontally 1 m behind the shaft 11. The seats 13 in the front row 12 are arranged somewhat lower than the seats in the rear row, and the headrests 14 in the front row 12 are correspondingly arranged below the pivot shaft 11. At the same time, however, the horizontal distance a between the head rest 14 of the front row 12 (in front of the axis 11) and the axis 11 is greater than the horizontal distance b between the head rest 14 of the rear row 12 and the axis 11 It is getting shorter. The horizontal distances a and b between the head rest 14 and the shaft 11 in each row 12 are both shorter than the horizontal dimension c of the seat 13 (including a portion on which the passenger places his / her feet). . The center of gravity (gravity line) SGes of the entire gondola 10 is positioned below the swing arm 11 by the front and rear seats 13.
Exists between As shown in FIG. 1, the left outrigger 5 is divided in the lateral direction. The divided distal end portion of the outrigger 5 extends around the axis 15 extending in a direction crossing the rotation axis 7 of the outrigger 5 around the rotation axis 7 of the outrigger 5.
It can be pivoted at some angle to the side parts in a hinged manner. As a result, even if the two outriggers 5 are out of parallel, no stress is applied to the gondola 10. The structure of the bearing 11a described below is considered to be supplementary. FIG. 5 shows the bearing 11a on an enlarged scale. The bearing 11a is attached to the outrigger 5 by a flange 16. As a result, the housing 17 of the bearing 11a forms a part of the outrigger 5. As can be seen from FIG. 6, the outrigger 5 has a housing for a braking device 33 which will be described in detail below.
Comes with 18. A ball bearing type rotary gear 19 having an outer ring 20 is held in the housing 18. The inner ring 21 of the rotating gear 19 forms a part of the hub 22 of the bearing 11a. A bearing bracket 24 holding a shaft 25 on the hub 22 is attached to the plate 23. A sleeve 27 to which the pendulum arm 10a of the gondola 10 is attached is supported on the shaft 25 via a ball ring 26. As a result, each pendulum arm 10a
Can be tilted a little against 1a. This type of movement is limited and attenuated with each movement by an axially biased rubber ring 28 (shown in FIG. 5). This rubber ring 28 is the coaxial projection of the shaft 25
Sleeve 30 on pendulum arm 10a
Surrounds the outer periphery. On the opposite side of the plate 23, a brake drum 31 interlocking with the brake lining 32 is mounted (33).
Represents the entire brake. ). The brake lining 32 concentrically surrounds the brake drum 31. Brake 33 is a bent passenger gondola
10 is laid out so that it can resist the torque exerted on the outrigger 5. Even if the gondola 10 is full during the above-described operation cycle, it is possible to resist. Brakes (already described as a locking device by the layout already described)
The movement of 33 is accomplished with the help of a concentric hose 34. The hose 34 is located outside the brake 33 and can apply a force inward in the axial direction to the brake shoe 32 movable in the axial direction with the help of the compressed air. FIG. 7 shows a water tank provided outside the support member 3 (the whole is denoted by reference numeral 35). Although not shown in FIG. 1, such water tanks are provided on the gantry 1 in FIG. 1 at positions on the right side of the support member 3 and on the left side of the support member 2, respectively. The water tank 35 shown in FIG.
It is in an operating state, that is, in a state where water is filled and vertically extended, and at a position where a load is to be loaded on the gantry 1 (not shown in FIG. 7) with the help of the weight of water. The water tank 35 comprises four concentric annular members 36, 37, 38 and 39, as shown in FIG. A container (not shown) made of a suitable plastic film or the like is attached to the inner upper edge of the annular member 39. When assembling the vehicle, for example, the support member 3 is connected to the upper edge of the annular member 38 via a connector 40 (shown in FIG. 7), and water is supplied from outside the water tank to the inside of the container. The outer shape of the container expands to form the outer annular member 36.
Push up the annular members 37, 38 and 39 against. As a result, the water tank 35 is in an extended state as shown in FIG.
The support member 3 can be raised. When necessary operations such as fixing the raised support member 3 are performed and the assembly of the vehicle is completed, the connector 40 is released and the water inside the container is discharged out of the water tank, and the annular members 37, 3
8 and 39 are lowered, and the water tank 35 is contracted in the vertical direction. As a result, the total height of the water tank 35 does not exceed the height allowed in the operating state. When the water tank 35 contracts, the container is folded at the lower part of the water tank 35. As can be seen from the shaft 41 shown in FIG.
When this flipping swing is configured as a movable vehicle, an axis extending laterally (and horizontally) to the axes 7 and 11 on the gantry 1 (the axis of the support member 3 indicates the axis 41, Around the member 2) (not shown), they are hinged to each other in a tiltable manner. Here, the hinge shaft is arranged at various heights above the gantry 1. That is, in both the space saving type and the safe transport type, the hinge shafts can be put on each other together with the hub 4 of the outrigger 5 for transport. FIGS. 9 (a) to 9 (e) show the progress of an operation cycle with one rotation of the outrigger 5 in conjunction with the gondola 10 flipping. The position shown in FIG. 2A is treated as the first or rest position where passengers can get on and off. The outrigger 5 faces downward, and the gondola 10 hangs radially outward. At the start of the operation,
As shown in FIG. 3B, the outrigger 5 is first pushed out clockwise by an angle α. At that time, gondola 10
Means that the vertical main surface is at an angle of 180-α with the main surface of the outrigger 5.
As if hanging vertically.
When the predetermined angular position is reached, the brake 33 locks the outrigger 5 and the gondola 10 at the aforementioned angular position. Next, as shown in FIG.
It is rotated counterclockwise integrally with the gondola 10 that is locked and does not change its relative position. As a result, this gondola 10 comes to a position over the head. FIG. 3C simultaneously shows a state immediately before the outrigger 5 reaches the top dead center (apex position).
At this time, the center of gravity of the gondola 10 has reached the opposite side because the gondola 10 is at a position inclined with respect to the outrigger 5. Therefore, it is already unbalanced to rotate counterclockwise with the outrigger 5 as before. At this moment, the brake 33 is released and the lock ends. This allows the gondola 10 to descend diagonally, as shown in FIG. During this operation, the outrigger 5 further rotates.
Helps 10 to somersault. As shown in FIG. 3E, the gondola 10 performs a somersault when the outrigger 5 comes to a substantially horizontal position.
