Abstract

PURPOSE: To prevent the heads and necks of passengers from being exposed to excessively high acceleration by placing headrests for the passenger seat of a passenger conveyor in positions not so distant from the rocking shaft of a gondola. CONSTITUTION: Two vertical support members 2, 3 are mounted on a frame 1, and the hub 4 of an outrigger-shaped member 5 is supported on the upper end of each vertical support member 2, 3. The hub 4 is rotated in the normal or reverse direction by an electric motor 6 at a predetermined rotating speed. A passenger gondola 10 is supported on the free end of the outrigger-shaped member 5 while in a state in which it can freely rock about 11 extending parallel to a shaft 7. Lines 12 of seats 13 for passengers are arranged in steps at different heights inside the passenger conveyor 10, with each line 12 extended parallel to the shaft 7. Headrests 14 are placed at the passenger seats 13 at a short distance from the racking shaft 11 of the passenger gondola 10. The head of the passenger is located slightly below the rocking shaft so that a centrifugal force resulting from overturning does not impart a dangerous compressive force to the spine.

Description

[Detailed description of the invention] [Industrial application field]

In this invention, the outrigger-like member is arranged between two parallel outrigger-like members that are rotatably supported around an axis extending between two vertical support members arranged on a frame and can be driven by a motor. The present invention relates to a somersault swing in which a passenger gondola for selecting passenger seats arranged in rows extending parallel to the axis of the member is suspended in a pendulum shape at both ends, and a method for driving the same.

[Prior Art and Problems to be Solved by the Invention] This type of vehicle has already achieved the goal of possibility, gives a strong impression when moving, and can be assembled and disassembled quickly and easily. proposed (DE-A-33
21599). Assembly and disassembly work is quick and easy because
This is achieved by providing a support member that can be extended and retracted and pivoted on the cradle. On the other hand, the sensation of movement occurs when a normal somersault swing has outriggers.
This corresponds to being suspended from a shaped member in a freely swinging state. Known somersault swing (the above DE, -A-332159
9), p. 10, middle row. ) depending on
We already know that somersaulting vehicles are not practical. In order for a passenger gondola to somersault, the passengers must be exposed to such high accelerations within the rows of seats located so far below the axis of rotation that the somersault motion cannot be tolerated from a medical point of view. There isn't. In contrast, the somersault swing of the present invention provides a relatively simple method using a normal somersault swing that does not expose the passengers to excessive acceleration (albeit high acceleration) and provides entertainment for the passengers. You can experience being on board. At this time, each passenger
In substantially the same way as in the vehicle described in item 0, each person is seated independently in a passenger condola (in addition,
This EPB 1-140-230 vehicle is only capable of somersaults in a gondola. )

[Means for Solving the Problems, Operations and Effects] In the present invention, the head rest of the passenger seat of the passenger gondola is arranged at a position not far away from the swing axis of the gondola. In this way, the passenger's head and neck are not exposed to excessively high accelerations using simple means. Here, as the passenger gondola somersaults, the outrigger
The centrifugal force of the gondola itself is added to the centrifugal force of the shaped member. In the descending state, the Earth's gravitational pull is further applied. As a result, the entire acceleration is calculated to be dangerous to the entire neck (whiplash effect) when it is aligned perpendicular to the column. Therefore, it is recommended that the receiver be arranged so that the horizontal component of the distance from the swing axis to the head is relatively short, while taking into account the appropriate distance from the swing axis to the center of gravity of the entire gondola in which passengers or passengers are riding. It will be done. 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 somersault will not exert any dangerous compressive force on the column. The arrangement of the head rests of the passenger seats in the vicinity of the above-mentioned swing axis can be realized in various ways. If the rows of seats are oriented in the same direction and one is arranged in a stepped manner behind the other, the distance of the seats in the rear row from the above-mentioned pivot axis can be greater than that of the seats in the front row in the viewing direction. , should also be larger. This is because the head rests in the rear row face toward the pivot axis, and the heads of the passengers sitting in the seats are pressed against the head rests during somersaults. On the other hand, the seats in the front row are placed far forward due to space constraints, as the head restraints in the front row and the above-mentioned rocking shaft behind the passenger receive a force that causes a slight pitching motion (forward) during a somersault. It needs 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 restraints. It is also preferred that the pendulum bearing of the passenger gondola (on the pendulum arm) is provided with a locking device by which the passenger gondola can be fixed in a particular angular position relative to the outrigger-like member. This kind of arrangement allows the boarding cycle to pass downwards at some point. In particular, the locking device preferably comprises a brake located within the outrigger-like member concentrically with respect to a brake drum mounted on the gondola side bearing section. This not only allows the gondola to be locked in any angular position relative to the outrigger-like member, but also allows the gondola to be locked in any angular position relative to the outrigger-like member, depending on the force of the brake when desired or required. It is possible to influence the rocking (pendulum movement) of the passenger gondola. A further improvement in this new somersault swing is that each pendulum arm of the passenger gondola is connected to a cardan shaft attached to the outrigger by an axis extending transversely to the axis of rotation of the outrigger. The outrigger-like member is held in place and can be thrown out at a small angle relative to the outrigger-like member. This avoids stress on the passenger gondola having the support member, the outrigger-like member and the pendulum arm. This stress is caused by the irregularities that occur when setting up the somersault swing as a vehicle, and cannot be avoided. Here, the angle at which each of the pendulum arms is thrown is limited by a tapered annular rubber member attached to the coaxial projection of the shaft and circumferentially surrounded by the pendulum arm. At the same time, this annular rubber member damps the load fluctuations that occur on the passenger gondola during somersaults. Similarly, the above stress can also be averaged by the means described below. That is, one of the outrigger-like members is split horizontally with respect to the radial direction in which the outrigger-like member extends vertically, and both of the split parts are split horizontally to the rotation axis of the outrigger-like member. It is a mutually restricted rotation around an extending axis. Finally, there is a measure of advantage for somersault trapeze vehicles that are mounted on a trestle. In other words, in order to load cargo onto the rack, they fit into each other like a telescope,
or an aquarium consisting of a plurality of annular members capable of collapsing vertically and coaxially, one attached to the inside of this aquarium and a ring at the top lining the aquarium when the aquarium is in an extended state; and a retractable container that can be folded together with the water tank when the water tank is in a compressed and empty state. In this case, the total height of the tank when it is empty does not exceed the height allowed under operating conditions, and the auxiliary equipment for supplying the required amount of water can be provided over a relatively small area. be carried on. Furthermore, this invention develops into a special driving method for this type of somersault swing. This driving method includes, at the beginning of a movement cycle, throwing out the outrigger-like member in a state that makes an acute angle to the vertically downward direction against the direction of forward rotation;
Note that after locking the vertically suspended passenger gondola to the outrigger-like member, the outrigger-like member is rotated in the forward direction together with the passenger gondola tilted in the forward direction, so that the outrigger-like member The gondola is characterized in that the lock of the gondola is released when the center of gravity of the gondola passes directly above the swing axis immediately before reaching the top dead center. This last-mentioned method leads to the passenger gondola being tilted forward and lowered before reaching the overhead position (upside down position). The gondola swings around the swing axis, and at the same time is overtaken by a certain amount by the rotating outrigger-like member. As a result, the passenger gondola is not affected by any other effects.
Moreover, he will perform somersaults without leaving the platform. The flow of the somersault process can be influenced temporally and spatially by the driving speed (rotational speed) of the outrigger-like member. As a result, a further somersault may not occur, or only a second somersault may occur. The passenger gondola can also be locked with the aid of the brakes relative to the outrigger-like member. Such a brake is used to immediately influence 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 Figure 1, there are two
Two vertical support members 2 and 3 are attached. A knob 4 of an outrigger-like member 5 is pivotally supported at the upper end of each of the vertical support members 2, 3. The hub 4 is driven by an electric motor 6 to rotate forward or backward at a predetermined rotational speed. The rotary drives on both sides are connected to each other by a cardan shaft 7. On the opposite side of the hub 4, the outrigger-like member 5 has a counterbalance part 5a to which a counterweight 9 is attached. The dimensions of these counterweights 9 are preferentially designed so that the total weight matches the total weight of the passenger gondola 10 when weighed flat. A passenger gondola 10 is pivotally supported at the free end of the rigger-like member 5 so as to be able to swing freely around a shaft 11 extending parallel to the shaft 7. In reality, the pendulum arm 10a, which is shorter in size than the outrigger-like member 5, is used to swing the pendulum arm 10a. As shown in FIG. 6, a brake 33 is attached to each bearing 11a,
This brake 33 influences the swinging of the passenger gondola 10, or locks the pendulum arm 10a at a predetermined angular position with respect to the outrigger-like member 5. The four rows 12 of seats 13 for passengers are arranged in a stepped manner at different heights in the passenger gondola 10, and in practice are arranged such that each row 12 extends parallel to the shaft 7. . The seat 13 is arranged with respect to the swing axis 11 as shown in FIG.
It is set aside. Seats 13 in the back row 12 are at the same height as the axis 11 and have a head restraint 1 horizontally 1 m behind the axis 11.
4 (attached to a stationary gondola 10). The seats 13 of the front row 12 are arranged somewhat lower than the seats of the rear row, and the head rests 14 of the front row 12 are arranged correspondingly below the pivot axis 11. However, at the same time, the head restraints 14 (axis 1
The horizontal distance between the shaft 11 (in front of the gondola 1) and the shaft 11 is shorter than the horizontal distance between the head rest 14 of the rear row 13 and the shaft 11.The center of gravity (line of gravity) of the entire gondola 10 SGes is the front and rear seats 1 below the swing arm 11.
Exists between 3. As shown in FIG. 1, the left outrigger-like member 5 is split laterally, and the two split parts are hinged to each other around an axis 15 so that they can pivot. ing. As a result, even if the two outrigger-like members 5 become out of parallel, no stress is applied to the gondola 1o. Bearing 1 described below
The structure of 1a is considered complementary. FIG. 5 shows the bearing 1t11a on an enlarged scale. This bearing 11a is attached to the outrigger-like member 5 by a flange 16. As a result, the housing 17 of the bearing it11a constitutes a part of the outrigger-like member 5. Also, as can be seen from Figure 6,
Attached to this outrigger-like member 5 is a housing 18 of a braking device 33, which will be described in detail below. A ball bearing rotating gear 19 having an outer ring 2o is held within the housing 18. The inner ring 21 of the rotating gear 19 constitutes a part of the hub 22 of the bearing it11a. A bearing bracket 24 holding a shaft 25 on the hub 22 is attached to the pool 23. A sleeve 27 to which a pendulum arm 10a of the gondola 1o is attached is pivotally supported on the shaft 25 via a ball ring portion 26. This allows each pendulum arm 10a to be thrown out a little relative to the bearing 11a. This type of movement is limited and damped at each movement by an axially tapered rubber ring 28 (shown in FIG. 6). This rubber ring 28 is attached to a coaxial projection 29 of the shaft 25 and is surrounded on its outer periphery by the sleeve 3o on the pendulum arm 10a. On the opposite side of the plate 23 is a brake lining 32.
A brake drum 31 is attached which is interlocked with the brake drum 31 (33 represents the entire brake). This brake lining 32 concentrically surrounds the brake drum 3I. The brake 33 is laid out to resist the torque exerted by the bent passenger bond 10 on the out IJ girder 5. It is possible to resist even if the gondola 1o is full during the above-mentioned operating cycle. The movement of the rake 33 (which is at the same time represented by the layout already described as a locking device) is accomplished with the aid of a concentric hose 34. hose 3
4 is located on the outside of the brake 33 and can exert a force axially inwardly on the axially movable brake shoe 32 with the aid of compressed air. FIG. 7 shows a water tank 35 provided outside the auxiliary member 3. Note that 35 represents the entire water tank and is omitted in FIG. 1. The water tank 35 shown in FIG. 7 is in operation and in position to load the vehicle cradle 1 shown here (not represented in FIG. 7) with the aid of the weight of the water. . As shown in FIG. 8, the water tank 35 consists of four concentric annular members 36, 37, .
It consists of 38 and 39. Each annular member 36°37
, 38 and 39 are pushed downward along the vertical axis after the tank 35 is empty and the connector 40 is released.
They are pushed into each other. A container (not shown) made of a suitable plastic film or the like is attached to the inside of the annular member 39. This container is attached to the upper edge of the top ring 39 and is adapted to fold into the bottom of the tank 35 when the tank 35 is empty and pushed downwards for a boarding operation. As can be seen from the eye 4 of the bearing shown in FIG. diagonally hinged opposite each other around an axis extending vertically (and horizontally). Here, the shafts of the hinges are arranged above the pedestal 1 at various heights. That is, both as a space-saving design and as a safe transport version, the hinge axes can be folded together with the hub 4 of the outrigger-like member 5 one on top of the other for transport. FIGS. 9(a) to 9(e) show the progression of the boarding cycle as the gondola 10 somersaults and the outrigger-like member 5 rotates once. The position shown in FIG. 4(a) is treated as the initial or resting position for passengers to get on and off. The outrigger-like member 5 faces downward,
The condoler 10 hangs radially outward. At the start of the movement operation, the outrigger
The shaped member 5 is first pushed out clockwise by an angle α. At this time, the gondola 10 hangs vertically downward such that its vertical main surface forms an angle 180-α with the main surface of the outrigger-like member 5. When this predetermined angular position is reached, the outrigger-like member 5 and the gondola 1
0 at the aforementioned angular position. Next, as shown in the same figure (c), the outrigger-like member 5
is rotated counterclockwise together with the gondola 10 which is locked and does not change its relative position. As a result, this gondola 10 comes to a position over head. The same figure (c) also shows the state just before the outrigger-like member 5 reaches the top dead center (point position). At this time, the center of gravity of the gondola 10 has reached the opposite side since the gondola 10 is in a tilted position with respect to the outrigger-like member 5. Therefore, it is already in an unbalanced state to rotate counterclockwise together with the outrigger-like member 5 as before. Brake 3 at this moment
3 is released and the lock ends. As a result, the gondola 10 descends diagonally and performs a counterclockwise rotation, as shown in FIG. 2(d). During this operation, the outrigger-like member 5 rotates further, thereby assisting the gondola 10 in somersaulting. As shown in FIG. 4(e), the gondola 10 performs a somersault when the outrigger-like member 5 comes to a substantially horizontal position.
